Literatura académica sobre el tema "Films DLC et BDD"

We investigated the atomic structure, electrical, and infrared range optical properties of diamondlike carbon (DLC) films containing alloy atoms (Cu, Ti, or Si) prepared by pulsed laser deposition. Radial distribution function (RDF) analysis of these films showed that they are largely sp3 bonded. Both pure DLC and DLC + Cu films form a Schottky barrier with the measuring probe, whereas DLC + Ti films behave like a linear resistor. Pure DLC films and those containing Cu exhibit p-type conduction, and those containing Ti and Si have n-type conduction. Photon-induced conduction is observed for pure DLC, and the mechanism is discussed in terms of low-density gap states of highly tetrahedral DLC. Our results are consistent with relative absence of gap states in pure DLC, in accordance with theoretical prediction by Drabold et al.37 Temperature dependence of conductivity of DLC + Cu shows a behavior σ ∞ exp(−B/T1/2), instead of the T−1/4 law (Mott–Davis law). Contributions from band-to-band transitions, free carriers, and phonons to the emissivity spectrum are clearly identified in pure DLC films. The amorphous state introduces a large contribution from localized states. Incorporation of a small amount of Si in the DLC does not change the general feature of emissivity spectrum but enhances the contribution from the localized states. Cu and Ti both enhance the free carrier and the localized state contributions and make the films a black body.

This work attempts to understand the behaviour of Ge-induced cytotoxicity of germanium-doped hydrogen-free diamond-like carbon (DLC) films recently thoroughly studied and published by Jelinek et al. At a low doping level, the films showed no cytotoxicity, while at a higher doping level, the films were found to exhibit medium to high cytotoxicity. We demonstrate, using surface-sensitive methods—two-angle X-ray-induced core-level photoelectron spectroscopy (ARXPS) and Low Energy Ion Scattering (LEIS) spectroscopy, that at a low doping level, the layers are capped by a carbon film which impedes the contact of Ge species with tissue. For higher Ge content in the DLC films, oxidized Ge species are located at the top surface of the layers, provoking cytotoxicity. The present results indicate no threshold for Ge concentration in cell culture substrate to avoid a severe toxic reaction.

The study is devoted to the development and testing of technological principles for the manufacture of solid end mills from ceramics based on a powder composition of α-SiAlON, β-SiAlON, and TiN additives, including spark plasma sintering powder composition, diamond sharpening of sintered ceramic blanks for shaping the cutting part of mills and deposition of anti-friction Si-containing diamond-like carbon (DLC) coatings in the final stage. A rational relationship between the components of the powder composition at spark plasma sintering was established. The influence of optimum temperature, which is the most critical sintering parameter, on ceramic samples’ basic physical and mechanical properties was investigated. DLC coatings’ role in changing the surface properties of ceramics based on SiAlON, such as microrelief, friction coefficient, et cetera, was studied. A comparative analysis of the efficiency of two tool options, such as developed samples of experimental mills made of SiAlON/TiN and commercial samples ceramic mills based on SiAlON, doped with stabilizing additives containing Yb when processing nickel alloys (NiCr20TiAl alloy was used as an example). DLC coatings’ contribution to the quantitative indicators of the durability of ceramic mills and the surface quality of machined products made of nickel alloy is shown.

Diamond always has been considered an exciting material. In addition to its other outstanding properties, diamond's capacity for cold electron emission has become a “hot” topic of research in recent years. The electron emission from diamond films is important for both fundamental and applied purposes, which may be expressed by two questions as follows: “Why does diamond emit electrons?” and “How can an efficient cold cathode be made?”The “diamond-emission era” started in 1991. That year three papers were published, reporting unexpectedly high electron emissivity from diamond. The first paper by Djubua and Chubun was very practical, having been written by device engineers. They tried different materials for the fabrication of pointed field emission cathodes and found that emitters made from diamondlike carbon (DLC) demonstrated a lower emission threshold compared to other materials. A second paper by Wang et al. reported a low emission threshold for chemical-vapor-deposition (CVD) diamond films, whereas a third paper by Geis et al. described the fabrication and operation of diamond cold cathodes.Since 1991 hundreds of papers about electron emission from diamond and diamondlike materials have been published. The motivations for this increasing activity are prospective applications in vacuum microelectronics—that is, vacuum emission devices fabricated by modern microelectronic technologies. Experts expect that combining the physical advantages of emission devices and the technological progress in solid-state microelectronics will result in the development of an entirely new generation of high-performance electronic devices—among them, flat-panel displays and miniature microwave tubes.

Self-determination theory offers valuable insight into supporting these women within their unique situations. INTRODUCTION In August of 2017, military and paramilitary forces in Myanmar began purging the Rohingya Muslim population from the country, motivated by anti-Muslim prejudice of the Buddhist political and social majority. Mass murder, property destruction, kidnapping, torture, and sexual violence still affect Rohingya communities. As a result, more than a million individuals have fled Myanmar.[1] As of February 2021, approximately 880,000 Rohingya Muslims have taken refuge in Cox’s Bazar, Bangladesh, the site of the largest refugee camps in the world.[2] The public health focus in these camps is on treatment of physical ailments and infectious diseases.[3] While women of reproductive age and adolescent girls experience the highest level of violence among Rohingya communities in both Myanmar and Bangladesh, they have consistently lacked access to sufficient sexual and reproductive care. In 1994, the Women’s Commission for Refugee Women and Children exposed issues surrounding the sexual and reproductive health of displaced populations and propelled the recognition of SRH as a human right.[4] Human rights interventionists and public health officials have made progress in the integration of sexual and reproductive health education, facilities, and resources into refugee camps in Cox’s Bazar. This includes the introduction of menstrual cleanliness facilities and educational conversations. However, Rohingya women and male cultural leaders, or gatekeepers, remain reluctant to accept these resources and education.[5] The prevalence of gender-based violence against women and restrictive policies enforced by the Bangladesh government heighten the barriers to the effective introduction of sexual and reproductive health resources and services.[6] A wealth of literature has pushed for the extension of clinical duties of beneficence and non-maleficence in the diagnosis and treatment of refugee and asylum-seeking communities.[7] Additionally, extensive research on Rohingya refugee communities has searched for ways to work around the complex social history and to accommodate power structures by integrating gatekeepers into SRH discussions.[8] However, as interventions have sought to overcome cultural and religious barriers, they have largely overlooked the protection of autonomy of sexual and reproductive health patients in Cox’s Bazar. This paper argues two points. First, attempts at improving outcomes in Cox’s Bazar ought to lead to Rohingya women’s autonomy and self-determination, both in mitigating control of male leaders over sexual and reproductive decisions and in ensuring the understanding and informed consent between patients and providers. Second, policy decisions ought to ensure post-treatment comprehensive care to shield Rohingya women from retribution by male community members. Self-determination theory offers guidance for state leaders and healthcare providers in pursuing these goals. l. Barriers to Sexual and Reproductive Health Services for Rohingya Women As part of its anti-Muslim narrative, the Buddhist majority has painted Rohingya women as hyper-reproductive. False narratives “of a Rohingya plan to spread Islam by driving demographic shifts” and accusations against Rohingya women for having “unusually large families” have motivated violent behavior and discriminatory regulations against Rohingya communities.[9] In reality, demographic data shows that “the Rohingya population has remained stable at 4% since 1980.”[10] In 2013, the government of Myanmar imposed regulations on Rohingya families in the Rakhine state, the region with the highest population of Rohingya Muslims, enforcing a two-child limit and requiring that Rohingya women obtain government authorization to marry and take a pregnancy test before receiving such permission. The majority has also subjected Rohingya females to acts of sexual violence to ostracize them and “dilute” Rohingya identity.[11] As a result, Rohingya women in Cox’s Bazar experience unique illnesses and vulnerabilities requiring imminent treatment. Due to national policies in Bangladesh, “Rohingya [women] cannot receive HIV/AIDS testing and treatment in camps; birth control implants delivered by midwives; and comprehensive abortion care.”[12] Additionally, in accordance with patriarchal Rohingya community structure, male gatekeepers hold high authority over sexual and reproductive decisions of women, evidenced by the persistence of gender-based violence within refugee camps and traditional practices such as the marriage of minor girls to older Rohingya men.[13] Surveys of community members reveal that cultural and religious stigma against sexual and reproductive health care exists among these male gatekeepers as well as Rohingya women.[14] Due to their cultural and political position, Rohingya women are subject to unique power relations. This paper analyzes the ethical dilemmas that arise from two of those power relations: Rohingya women’s relationships with male gatekeepers and their relationships with interventionist healthcare providers. ll. Ethics of Including Male Community Members in Decisions Affecting Women’s Healthcare Autonomy A November 2019 survey of Rohingya women in Cox’s Bazar that had married or given birth within the past two years found that “around one half of the female Rohingya refugees do not use contraceptives, mainly because of their husbands’ disapproval and their religious beliefs.”[15] There are widespread misconceptions such as the belief that Islam does not permit the use of contraceptives.[16] The existence of such misconceptions and the power husbands and male leaders hold over the delivery of treatment creates dilemmas for healthcare practitioners in conforming to ethical principles of care. lll. Beneficence in Providing Care to Refugees While public health scholars and government officials hold divided opinions on the level of treatment required to fulfill refugees’ right to sexual and reproductive health care, most support enough care to ensure physical and psychological well-being.[17] Beneficence requires that healthcare providers and states “protect the rights of others[,] prevent harm from occurring to others[, and] remove conditions that will cause harm to others.”[18] Under the principle of beneficence, there is a duty to provide sexual and reproductive treatment to Rohingya women in Cox’s Bazar that is comparable to that received by citizens of the host state. In addition, the ethical principle of nonmaleficence may call for the creation of specialized care facilities for refugee communities, because a lack of response to refugees’ vulnerability and psychological trauma has the potential to generate additional harm.[19] In response to gendered power relations among the Rohingya community, husbands and male leaders are included in decisions surrounding maternal health and sexual and reproductive care for women. For example, healthcare professionals “have been found to impose conditions on SRH [sexual reproductive health] care that are not stated in the national… [menstrual regulation] guidelines, such as having a husband’s permission.”[20] The refugee healthcare community could do more to mitigate the potential of retribution taken by male community members against women that accept care by dispelling common misconceptions and precluding male community members from influencing female reproductive choices.[21] However, some current practices allow the infiltration of male community leaders and husbands into the diagnosis, decision-making, and treatment spaces. Deferring decisions to male leaders for the sake of expediency risks conditioning women’s access to care on male buy-in and diminishes Rohingya women’s autonomy over their sexual and reproductive health. lV. Male Influence and Female Autonomy Ensuring patients control their own treatment decisions is an essential component of the ethical obligation of healthcare professionals to respect patients’ autonomy. While patients can exercise their autonomy to accept the direction of the community, their autonomy is undermined when “external sources or internal states… rob [such persons]… of self-directedness.”[22] Sexual and reproductive health research on Rohingya women revealed that the presence of male family members during conversations “made female respondents uncomfortable to speak openly about their SRH [sexual and reproductive health]related experiences.”[23] The same study found that when male family members were absent, Rohingya women were more transparent and willing to discuss such topics.[24] These findings indicate that the mere presence of male family members exerts control over Rohingya women in conversations with practitioners. Male involvement also stalls conversations between providers and Rohingya women which may harm the achievement of understanding and informed consent in diagnosis and treatment spaces.[25] Women do have the option of bringing their male community leaders and family members into sexual health discussions. Yet healthcare providers ought to monitor patients individually and avoid programmatic decision making regarding male involvement in the treatment space. While it is the ethical imperative of health interventionists and the state of Bangladesh to fulfill the duties of care required by the principles of beneficence and non-maleficence, the sole prioritization of expanding sexual and reproductive health care in Cox’s Bazar risks ignoring autonomy. V. Ethics of Paternalism in Provide-Patient Relations Rohingya women’s negative beliefs about contraceptives, such as the belief that they cause irreversible sterilization, are the second largest factor inhibiting their use.[26] To an extent, the Rohingya are justified in their skepticism. Prior to the 1990’s, Bangladesh used nonconsensual sterilization as a mechanism of population control to attain access to international aid. Though the international conversation surrounding reproduction shifted its focus towards reproductive rights following the 1994 UN International Conference on Population and Development, delivery of reproductive care in the global South is frequently characterized by lack of transparency and insufficient patient understanding of the risks and consequences of treatment. Additionally, women’s lack of control impacts follow-up care and long-term contraception. For example, when women seek the removal of implantable contraceptives, healthcare professionals often refuse to perform the requisite operation.[27] Patients must understand the risks of treatment in their own culture and circumstances where societal views, misconceptions, or fears may influence healthcare practices. Healthcare providers need to recognize the coercive potential they hold in their relations with patients and guard against breaches of patient autonomy in the delivery of treatment. In accordance with the principle of beneficence, healthcare providers treating refugees or individuals seeking asylum ought to abide by the same fiduciary responsibilities they hold toward citizens of the host state.[28] When patients show hesitancy or refusal toward treatment, healthcare providers ought to avoid achieving treatment by paternalistic practice such as “deception, lying, manipulation of information, nondisclosure of information, or coercion.”[29] Although well-intentioned, this practice undermines the providers’ obligation to respect patients’ autonomy.[30] The hesitancy of Rohingya women to accept some sexual or reproductive health care does not justify intentional lack of transparency, even when that treatment furthers their best health interests. However, paternalistic actions may be permissible and justified during medical emergencies.[31] Vl. Informed Consent Respecting Rohingya women’s autonomy also places affirmative duties on healthcare providers to satisfy understanding and informed consent. However, language barriers and healthcare providers’ misconceptions about Rohingya religion and culture impede the achievement of these core conditions of autonomy for Rohingya women.[32] In an interview, a paramedic in Cox’s Bazar described the types of conversations healthcare providers have with Rohingya women in convincing them to accept menstrual regulation treatment, a method to ensure that someone is not pregnant after a missed period: “We tell them [menstrual regulation] is not a sin… If you have another baby now, you will get bad impact on your health. You cannot give your children enough care. So, take MR [menstrual regulation] and care for your family.”[33] This message, like others conveyed to Rohingya women in counseling settings, carries unvalidated assumptions regarding the beliefs, needs, and desires of clients without making a proper attempt to confirm the truth of those assumptions. Healthcare providers’ lack of cultural competence and limited understanding of Bangladesh’s national reproductive health policy complicates communication with Rohingya women. Additionally, the use of simple language, though recommended by the WHO’s guideline on Bangladesh’s policy, is inadequate to sufficiently convey the risks and benefits of menstrual regulation and other treatments to Rohingya women.[34] For informed consent to be achieved, “the patient must have the capacity to be able to understand and assess the information given, communicate their choices and understand the consequences of their decision.”[35] Healthcare providers must convey sufficient information regarding the risks, benefits, and alternatives of treatment as well as the risks and benefits of forgoing treatment.[36] Sexual and reproductive health policies and practices must aim to simultaneously mitigate paternalism, promote voluntary and informed choice among Rohingya women, and foster cultural and political competency among healthcare providers. Vll. Self-Determination Theory Self-determination theory is a psychological model that focuses on types of natural motivation and argues for the fulfillment of three conditions shown to enhance self-motivation and well-being: autonomy, competence, and relatedness.[37] According to the theory, autonomy is “the perception of being the origin of one’s own behavior and experiencing volition in action;” competence is “the feeling of being effective in producing desired outcomes and exercising one’s capacities;” and, relatedness is “the feeling of being respected, understood, and cared for by others.”[38] Bioethicists have applied self-determination theory to health care to align the promotion of patient autonomy with traditional goals of enhancing patient well-being. Studies on the satisfaction of these conditions in healthcare contexts indicate that their fulfillment promotes better health outcomes in patients.[39] Like principlism, self-determination theory in Cox’s Bazar could allow for increased autonomy while maximizing the well-being of Rohingya women and behaving with beneficence Fostering self-determination requires that healthcare professionals provide patients with the opportunity and means of voicing their goals and concerns, convey all relevant information regarding treatment, and mitigate external sources of control where possible.[40] In Cox’s Bazar, health care organizations in the region and the international community can act to ensure women seeking health care are respected and able to act independently. A patient-centered care model would provide guidelines for the refugee setting.[41] Providers can maximize autonomy by utilizing language services to give SRH patients the opportunity and means to voice their goals and concerns, disclose sufficient information about risks, benefits, and alternatives to each procedure, and give rationales for each potential decision rather than prescribe a decision. They can promote the feeling of competence among patients by expressly notifying them of the level of reversibility of each treatment, introducing measures for health improvement, and outlining patients’ progress in their SRH health. Finally, they can promote relatedness by providing active listening cues and adopting an empathetic, rather than condescending, stance.[42] Healthcare organizations ought to provide training to promote cultural competency and ensure that practitioners are well-versed on national regulations regarding sexual reproductive health care in Bangladesh to avoid the presumption of patients’ desires and the addition of unnecessary barriers to care. Increased treatment options would make autonomy more valuable as women would have more care choices. Given the historical deference to international organizations like the UN and World Bank, multilateral and organizational intervention would likely bolster the expansion of treatment options. International organizations and donors ought to work with the government of Bangladesh to offer post-treatment comprehensive care and protection of women who choose treatment against the wishes of male community members to avoid continued backlash and foster relatedness.[43] CONCLUSION Rohingya women in Cox’s Bazar, Bangladesh face unique power relations that ought to be acknowledged and addressed to ensure that when they seek health care, they are able to act autonomously and decide freely among available options. While providers have duties under the principles of beneficence and non-maleficence, patient well-being is hindered when these duties are used to trump the obligation to respect patient autonomy. Current approaches to achieving sexual and reproductive health risk the imposition of provider and communal control. Self-determination theory offers avenues for global organizations, Bangladesh, donors, and healthcare providers to protect Rohingya women’s autonomous choices, while maximizing their well-being and minimizing harm. DISCLAIMER: As a male educated and brought up in a Western setting, I acknowledge my limitations in judgement about Rohingya women’s reproductive care. Their vulnerability and health risks can never be completely understood. To some extent, those limitations informed my theoretical approach and evaluation of Rohingya women's SRH care. Self-determination theory places the patients’ experiences and judgement at the center of decision-making. My most important contributions to the academic conversation surrounding Rohingya women are the identification of dilemmas where autonomy is at risk and advocating for self-determination. - [1] Hossain Mahbub, Abida Sultana, and Arindam Das, “Gender-based violence among Rohingya refugees in Bangladesh: a public health challenge,” Indian Journal of Medical Ethics (June 2018):1-2, https://doi.org/10.20529/IJME.2018.045.

One cannot use the Internet for long without encountering its many dead ends. Despite the adage that everything posted online stays there forever, users quickly discover how fleeting Web content can be. Whether it be the result of missing files, platform moderation, or simply bad code, the Internet constantly displaces its archival contents. Eventual decay is the fate of all digital media, as Wendy Hui Kyong Chun observed in a 2008 article. “Digital media is not always there”, she writes. “We suffer daily frustrations with digital sources that just disappear” (160). When the media content we seek is something trivial like a digitised vacation photo, our inability to retrieve it may merely disappoint us. But what happens when we lose access to Web content about significant cultural events, like viral misinformation about a school shooting? This question takes on great urgency as conspiracy content spreads online at baffling scale and unprecedented speed. Although conspiracy theories have long been a fixture of American culture, the contemporary Internet enables all manner of “information disorder” (Wardle and Derakhshan) to warp media coverage, sway public opinion, and even disrupt the function of government—as seen in the harrowing “Stop the Steal” attack on the U.S. Capitol on 6 January 2021, when rioters attempted to prevent Congress from verifying the results of the 2020 Presidential Election. Scholars across disciplines have sought to understand how conspiracy theories function within our current information ecosystem (Marwick and Lewis; Muirhead and Rosenblum; Phillips and Milner). Much contemporary research focusses on circulation, tracking how conspiracy theories and other types of misinformation travel from fringe Websites to mainstream news outlets such as the New York Times. While undoubtedly valuable, this emphasis on circulation provides an incomplete picture of online conspiracy theories’ lifecycle. How should scholars account for the afterlife of conspiracy content, such as links to conspiracy videos that get taken down for violating YouTube’s Community Guidelines? This and related questions about the dead ends of online conspiracy theorising are underexplored in the existing scholarly literature. This essay contends that the Internet’s tendency to decay ought to factor into our models of digital conspiracy theories. I focus on the phenomenon of malfunctional hyperlinks, one of the most common types of disrepair to which the Internet is prone. The product of so-called “link rot”, broken links would appear to signal an archival failure for online conspiracy theories. Yet recent work from rhetorical theorist Jenny Rice suggests that these broken hyperlinks instead function as a rhetorically potent archive in their own right. To understand this uncanny persuasive work, I draw from rhetorical theory to analyse broken links to conspiracy content on Reddit, the popular social news platform, surrounding the 2018 school shooting in Parkland, Florida, the worst high school shooting in American history. I show that broken links on the subreddit r/conspiracy, by virtue of their dysfunction, persuade conspiracy theorists that they possess “stigmatized knowledge” (Barkun 26) about the shooting that is being suppressed. Ultimately, I argue that link rot functions as a powerful source of evidence within digital conspiracy theories, imbuing broken links with enduring rhetorical force to validate marginalised belief systems. Link Rot—Archival Failure or Archival Possibility? As is suggested by the prefix ‘inter-’, connectivity has always been one of the Internet’s core functionalities. Indeed, the ability to hyperlink two different texts—and now images, videos, and other media—is so fundamental to navigating the Web that we often take these links for granted until they malfunction. In popular parlance, we then say we have clicked on a “broken” or “dead” link, and without proper care to prevent its occurrence, all URLs are susceptible to dying eventually (much like us mortals). This slow process of decay is known as “link rot”. The precise extent of link rot on the Internet is unknown—and likely unknowable, in practice if not principle—but multiple studies have been conducted to assess the degree of link rot in specific archives. One study from 2015 found that nearly 50% of the URLs cited in 406 library and information science journal articles published between 2008-2012 were no longer accessible (Kumar et al. 59). In the context of governmental Webpages, a 2010 study determined that while only 8% of the URLs sampled in 2008 had link rot, that number more than tripled to 28% of URLs with link rot when sampled only two years later (Rhodes 589-90). More recently, scholars from Harvard’s Berkman Klein Center for Internet and Society uncovered an alarming amount of link rot in the online archive of the New York Times, perhaps the most prominent newspaper in the United States: “25% of all links were completely inaccessible, with linkrot becoming more common over time – 6% of links from 2018 had rotted, as compared to 43% of links from 2008 and 72% of links from 1998” (Zittrain et al. 4). Taken together, these data indicate that link rot worsens over time, creating a serious obstacle for the study of Web-based phenomena. Link rot is particularly worrisome for researchers who study online misinformation (including digital conspiracy theories), because the associated links are often more vulnerable to removal due to content moderation or threats of legal action. How should scholars understand the function of link rot within digital conspiracy theories? If our academic focus is on how conspiracy theories circulate, these broken links might seem at best a roadblock to scholarly inquiry or at worst as totally insignificant or irrelevant. After all, users cannot access the material in question; they reach a dead end. Yet recent work by rhetoric scholar Jenny Rice suggests these dead ends might have enduring persuasive power. In her book Awful Archives: Conspiracy Rhetoric and Acts of Evidence, Rice argues that evidence is an “act rather than a thing” and that as a result, we ought to recalibrate what we consider an archive (12, original emphasis). For Rice, archives are more than simple aggregates of documents; instead, they are “ordinary and extraordinary experiences in public life that leave lasting, palpable residues, which then become our sources—our resources—for public discourse” (16-17). These “lasting, palpable residues” are deeply embodied, Rice maintains, for the evidence we gather is “always real in its reference, which is to a felt experience of proximities” (118). For conspiracy theorists in particular, an archive might evoke a profound sense of what Rice memorably describes as “Something intense, something real. Something off. Something fucked up. Something anomalous” (12, original emphasis). This is no less true when an archive fails to function as designed. Hence, for the remainder of this essay, I pivot to analysing how link rot functions within digital conspiracy theories about the 2018 school shooting in Parkland, Florida. As we will see, the shooting galvanised meaningful gun control activism via the March for Our Lives movement, but the event also quickly became fodder for proliferating conspiracy content. From Crisis to Crisis Actors: The Parkland Shooting and Its Aftermath On the afternoon of 14 February 2018, Nikolas Cruz entered his former high school, Marjory Stoneman Douglas, and murdered 17 people, including 14 students (Albright). While a horrific event, the Parkland shooting unfortunately marked merely the latest in a long line of similar tragedies in the United States, which has been punctuated by school shootings for decades. But the Parkland shooting stands out among the gruesome lineage of similar tragedies due to the profound resolve of its student-survivors, who agitated for gun policy reform through the March for Our Lives movement. In the weeks following the shooting, a group of Parkland students partnered with Everytown for Gun Safety, a non-profit organisation advocating for gun control, to coordinate a youth-led demonstration against gun violence. Held in the U.S. capitol of Washington, D.C. on 24 March 2018, the March for Our Lives protest was the largest demonstration against gun violence in American history (March for Our Lives). The protest drew around 200,000 participants to Washington; hundreds of thousands of protestors attended an estimated 800 smaller rallies held across the United States (CBS News). Furthermore, likeminded protestors across Europe, Asia, Africa, and Australia held allied events to show support for these American students’ cause (Russo). The broader March for Our Lives organisation developed out of the political demonstrations on 24 March 2018; four years later, March for Our Lives continues to be a major force in debates about gun violence in the United States. Although the Parkland shooting inspired meaningful gun control activism, it also quickly provoked a deluge of online conspiracy theories about the tragedy and the people involved, including the student-activists who survived the shooting and spearheaded March for Our Lives. This conspiracy content arrived at breakneck pace: according to an analysis by the Washington Post, the first conspiracy posts appeared on the platform 8chan a mere 47 minutes after the first news reports aired about the shooting (Timberg and Harwell). Later that day, Parkland conspiracy theories migrated from fringe haunts like 8chan to InfoWars, a mainstay of the conspiracy media circuit, where host/founder Alex Jones insinuated that the shooting could be a “false flag” event orchestrated by the Democratic Party (Media Matters Staff). Over the ensuing hours, days, weeks, and months, Parkland conspiracies continued to circulate, receiving mainstream news coverage when conversative activists and politicians publicly espoused conspiracy claims about the shooting (Arkin and Popken). Ultimately, the conspiracist backlash was so persistent and virulent throughout 2018 that PolitiFact, a fact-checking site run by the Poynter Institute, declared the Parkland conspiracy theories their 2018 “Lie of the Year” (Drobnic Holan and Sherman). As with many conspiracy theories, the Parkland conspiracies remixed novel information with longstanding conspiracist tropes. Predominantly, these theories alleged that the Parkland student-activists who founded March for Our Lives were being controlled by outside forces to do their bidding. Although conspiracy theorists diverged in who they named as the shadowy puppet master pulling the strings—was it the Democratic Party? George Soros? Someone else?—all agreed that a secretive agenda was afoot. The most extreme version of this theory held that David Hogg, X González, and other prominent March for Our Lives activists were “crisis actors”. This account envisions Hogg et al. as paid performers playing the part of angry and traumatised students for media coverage about a school shooting that either did not occur as reported or did not occur at all (Yglesias). While unnerving and callous, these crisis actor allegations are not new ideas; rather, they draw from a long history of loosely antisemitic “New World Order” conspiracy theories that see an ulterior motive behind significant historical events (Barkun 39-65). Parkland conspiracy theorists circulated a wide variety of media artifacts—anti-March for Our Lives memes, obscure blog posts, and manipulated video footage of the Parkland students, among other content—to propagate their crisis actor claims. But whether due to platform moderation, threat of legal action, or simply public pressure, much of this conspiracy material is now inaccessible, leaving behind only broken links to conspiracy content that once was. By closely examining these broken links through a rhetorical lens, we can trace the “lasting, palpable residues” (Rice 16) link rot leaves in its wake. “All part of the purge”: Parkland Link Rot on r/conspiracy In this final section, I use the tools of rhetorical analysis to demonstrate how link rot can function as a form of evidence for conspiracy theorists. Rhetorical analysis, when applied to digital infrastructure, requires that we expand our notion of rhetoric beyond intentional human persuasion. As James J. Brown, Jr. argues, digital infrastructure is rhetorical because it determines “what’s possible in a given space”, which may or may not involve human beings (99). Human intentionality still matters in many contexts, of course, but seeing digital infrastructure as a “possibility space” opens up productive new avenues for rhetorical inquiry (Brown, Jr. 72-99). This rhetorical perspective aligns with the method of “affordance analysis” derived from Science and Technology Studies and related fields, which investigates how technologies facilitate certain outcomes for users (Curinga). Much like an affordance analysis, my goal is to illustrate how broken links produce certain rhetorical effects, not to make broader empirical claims about the extent of link rot within Parkland conspiracy theories. The r/conspiracy page on Reddit, the popular social news platform, serves as an ideal site for conducting a rhetorical analysis of broken links. The r/conspiracy subreddit is a preeminent hub for digital conspiracy content, with nearly 1.7 million members as of March 2022 and thousands of active users viewing the site at any given time (r/conspiracy). Beyond its popularity, Reddit’s platform design makes link rot a common feature on r/conspiracy. As a forum-based social media platform, Reddit consists entirely of subreddits dedicated to various topics. In each subreddit, users generate and contribute to threads with relevant content, which often entails posting links to materials hosted elsewhere on the Internet. Importantly, Reddit allows each subreddit to set its own specific community rules for content moderation (so long as these rules themselves abide by Reddit’s general Content Policy), and unlike other profile-based social media platforms, Reddit allows anonymity through the use of pseudonyms. For all of these reasons, one finds a high frequency of link rot on r/conspiracy, as posts linking to external conspiracy media stay up even when the linked content itself disappears from the Web. Consider the following screenshot of an r/conspiracy Parkland post from 23 February 2018, a mere nine days after the Parkland shooting, which demonstrates what conspiracist link rot looks like on Reddit (fig. 1). Titling their thread “A compilation of anomalies from the Parkland shooting that the media won't address. The media wants to control the narrative. Feel free to use this if you find it helpful”, this unknown Redditor frames their post as an intervention against media suppression of suspicious details (“A compilation of anomalies”). Yet the archive this poster hoped to share with likeminded users has all but disintegrated—the poster’s account has been deleted (whether by will or force), and the promised “compilation of anomalies” no longer exists. Instead, the link under the headline sends users to a blank screen with the generic message “If you are looking for an image, it was probably deleted” (fig. 2). Fittingly, the links that the sole commenter assembled to support the original poster are also rife with link rot. Of the five links in the comment, only the first one works as intended; the other four videos have been removed from Google and YouTube, with corresponding error messages informing users that the linked content is inaccessible. Fig. 1: Parkland Link Rot on r/conspiracy. (As a precaution, I have blacked out the commenter’s username.) Fig. 2: Error message received when clicking on the primary link in Figure 1. Returning to Jenny Rice’s theory of “evidentiary acts” (173), how might the broken links in Figure 1 be persuasive despite their inability to transport users to the archive in question? For conspiracy theorists who believe they possess “stigmatized knowledge” (Barkun 26) about the Parkland shooting, link rot paradoxically serves as powerful validation of their beliefs. The unknown user who posted this thread alleges a media blackout of sorts, one in which “the media wants to control the narrative”. This claim, if true, would be difficult to verify. Interested users would have to scour media coverage of Parkland to assess whether the media have ignored the “compilation of anomalies” the poster insists they have uncovered and then evaluate the significance of those oddities. But link rot here produces a powerful evidentiary shortcut: the alleged “compilation of anomalies” cannot be accessed, seemingly confirming the poster’s claims to have secretive information about the Parkland shooting that the media wish to suppress. Indeed, what better proof of media censorship than seeing links to professed evidence deteriorate before your very eyes? In a strange way, then, it is through objective archival failure that broken links function as potent subjective evidence for Parkland conspiracy theories. Comments about Parkland link rot elsewhere on r/conspiracy further showcase how broken links can validate conspiracy theorists’ marginalised belief systems. For example, in a thread titled “Searching for video of Parkland shooting on bitchute”, a Redditor observes, “Once someone gives the link watch it go poof”, implying that links to conspiracy content disappear due to censorship by an unnamed force (“Searching for video”). That nearly everything else on this particular thread suffers from link rot—the original poster, the content of their post, and most of the other comments have since been deleted—seems only to confirm the commentor’s ominous prediction. In another thread about a since-deleted YouTube video supposedly “exposing” Parkland students as crisis actors, a user notes, “You can tell there’s an agenda with how quickly this video was removed by YouTube” (“Video Exposing”). Finally, in a thread dedicated to an alleged “Social Media Purge”, Redditors share strategies for combating link rot, such as downloading conspiracy materials and backing them up on external hard drives. The original poster warns their fellow users that even r/conspiracy is not safe from censorship, for removal of content about Parkland and other conspiracies is “all part of the purge” (“the coming Social Media Purge”). In sum, these comments suggest that link rot on r/conspiracy persuades users that their ideas and their communities are under threat, further entrenching their conspiratorial worldviews. I have argued in this article that link rot has a counterintuitive rhetorical effect: in generating untold numbers of broken links, link rot supplies conspiracy theorists with persuasive evidence for the validity of their beliefs. These and other dead ends on the Internet are significant yet understudied components of digital conspiracy theories that merit greater scholarly attention. Needless to say, I can only gesture here to the sheer scale of dead ends within online conspiracy communities on Reddit and elsewhere. Future research ought to trace other permutations of these dead ends, unearthing how they persuade users from beyond the Internet’s grave.

India has one of the world’s highest proportions of plant-based consumers relative to its total population (Sawe). However, the view that India is a predominantly vegetarian nation is likely inaccurate, as recent findings from the 2014 Indian Census indicate that only three in ten Indians self-identity as vegetarian (Census of India). Other studies similarly estimate the prevalence of vegetarianism to range from about 25% (Mintel Global) to about 40% (Euromonitor International; Statista, “Share”), and many Indians are shifting from strict plant-based diets to more flexible versions of plant-based eating (Food and Agriculture Organization of the United Nations). When it comes to meat eating, poultry is the most widely consumed (USDA Foreign Agricultural Service; Organisation for Economic Co-operation and Development). Some claim that the changing consumer landscape is also eroding traditional taboos associated with beef and buffalo meat consumption (Kala; Bansal), with many tending to underreport their meat consumption due to religious and cultural stigmas (Bansal).This change in food choices is driven by several factors, such as increasing urbanisation (Devi et al.), rising disposable incomes (Devi et al.; Rukhmini), globalisation, and cross-cultural influences (Majumdar; Sinha). Today, the urban middle-class is one of India’s fastest growing consumer segments (Wharton School of the University of Pennsylvania), and the rise in the consumption of animal products is primarily occurring in urban India (National Sample Survey Office), making this an important market to investigate.From a global perspective, while many Western nations are increasingly adopting plant-based diets (Eswaran), the growth in meat consumption is predicted to mainly come from emerging markets (OECD/FAO) like India. With these points in mind, the purpose of this study was to explore contemporary eating practices in urban India and to understand how social structures, cultures, and traditions influence these practices. The findings indicate that the key reasons why many are transitioning away from plant-based diets are the rise of new and diverse meat-based foods in urban India, emerging tastes for meat-based cuisines, and meat becoming to be viewed as a status symbol. These factors are further elaborated upon in this article.MethodA key question of this research was “What are eating practices like in urban India today?” The question itself is a challenge, given India’s varied cultures and traditions, along with its myriad eating practices. Given this diversity, the study used an exploratory qualitative approach, where the main mode of data gathering was twenty-five unstructured individual face-to-face interviews, each approximately sixty minutes in duration. The discussions were left largely open to allow participants to share their unique eating practices and reflect on how their practices are shaped by other socio-cultural practices. The research used an iterative study design, which entailed cycles of simultaneous data collection, analysis, and subsequent adaptations made to some questions to refine the emerging theory. Within the defined parameters of the research objectives, saturation was adequately reached upon completion of twenty-five interviews.The sample comprised Mumbai residents aged 23 to 45 years, which is fairly representative given about a third of India’s population is aged under 40 (Central Intelligence Agency). Mumbai was selected as it is one of India’s largest cities (Central Intelligence Agency) and is considered the country’s commercial capital (Raghavan) and multicultural hub (Gulliver). The interviews were conducted at a popular restaurant in downtown Mumbai. The interviews were conducted predominantly in English, as it is India’s subsidiary official language (Central Intelligence Agency) and the participants were comfortable conversing in English. The sample included participants from two of India’s largest religions—Hindus (80%) and Muslims (13%) (Registrar General and Census Commissioner of India), and comprised an even split of males and females.The Market Research Society of India has developed a socio-economic classification (SEC) grid that segments urban households into twelve groups (Market Research Society of India). This segmentation is based on two questions: level of education—from illiteracy to a postgraduate degree—and the ownership of eleven items that range from fairly basic (e.g., electricity connection, gas stove) to relatively sophisticated (e.g., refrigerator, personal computer). As previous qualitative work has found that education levels and disposable incomes can significantly impact one’s ability to make informed and deliberate food choices (Khara), and given meat is a relatively expensive commodity in India (Puskar-Pasewicz), the study focused on the most affluent segments—i.e., SEC A1 and some of SEC A2.It is said that researcher values and predispositions are to some extent inseparable from the research process, and therefore that potential researcher bias must be managed by being self-aware, looking for contradictory data, and being open to different interpretations of the data (Ogden). As the interviewer is a vegan of Indian ethnicity, she attempted to manage researcher bias in several ways. Triangulation of data sources (e.g., interviews, observations, product analysis) helped provide a multi-faceted understanding of the topic (Patton). The discussion guide and findings were also discussed with researchers from different cultural and dietary backgrounds. It is also argued that when a researcher shares the same background as the participants—as was the case in this study—participants may remain silent on certain issues, as they may assume the researcher knows the context and nuances in relation to these issues (McGinn). This arose in some instances as some participants said, “it’s standard stuff you know?” The interviewer hence took an “outsider” role, stating “I’ll need to know what standard stuff is”, so as to reduce any expectation that she ought to understand the social norms, conventions, and cultural practices related to the issue (Leckie). This helped yield more elaborate discussions and greater insight into the topic from the participant’s own unique perspective.The Rise of New and Diverse Meat-based Foods in Urban India Since the early 1990s, which marked the beginning of globalisation in India, urban Indian food culture has undergone a significant change as food imports have been liberalised and international food brands have made their way into the domestic market (Vepa). As a result, India’s major urban centres appear to be witnessing a food revolution:Bombay has become so metropolitan, I mean it always was but it’s so much more in terms of food now … and it’s so tempting. (Female, age 32)The changing food culture has also seen an increase in new dishes, such as a lamb burger stuffed with blue cheese, and the desire to try out exotic meats such as octopus, camel, rabbit, and emu. Many participants described themselves as “food obsessed” and living in a “present and continuous state of food”, where “we finish a meal and we’ve already started discussing our next meal”.In comparison, traditional plant-based foods were seen to have not undergone the same transformation and were described as “boring” and “standard” in comparison to the more interesting and diverse meat-based dishes:a standard restaurant menu, you don’t have all the different leafy vegetables…It’s mostly a few paneer and this or that—and upon that they don’t do much justice to the vegetable itself. It’s the same masala which they mix in it so everything tastes the same to me. So that’s a big difference when you consider meats. If I eat chicken in different preparations it has a different taste, if I have fish each has a different taste. (Male, age 29)If I’m going out and I’m spending, then I’m not going to eat the same thing which I eat at home every day which is veg food ... I will always pick the non-vegetarian option. (Male, age 32)Liberalisation and the transformation of the local media landscape also appears to have encouraged a new form of consumerism (Sinha). One participant described how an array of new TV channels and programmes have opened up new horizons for food:The whole visual attraction of food, getting it into your living room or into your bedroom and showing you all this great stuff … [There are now] kiddie birthdays which are MasterChef birthdays. There are MasterChef team building activities … So food is very big and I think media has had a very, very large role to play in that. (Female, age 40+)In a similar vein, digital media has also helped shape the food revolution. India has the world’s second largest number of Internet users (Statista, Internet) and new technology seems to have changed the way urban Indians interact with food:We are using social sites. We see all the cooking tips and all the recipes. I have a wife and she’s like, “Oh, let’s cook it!” (Male, age 25)I see everything on YouTube and food channels and all that. I really like the presentation, how they just a little they cook the chicken breast. (Female, age 42)Smartphones and apps have also made access to new cuisines easier, and some participants have become accustomed to instant gratification, givendelivery boys who can satisfy your craving by delivering it to you … You order food from “Zomato” at twelve o’clock, one o’clock also. And order from “Sigree” in the morning also nowadays … more delivery options are there in India. (Male, age 30)This may also partially explain the growing popularity of fusion foods, which include meat-based variations of traditional plant-based dishes, such as meat-filled dosas and parathas.Emerging Tastes for Meat-based Cuisines Many highlighted the sensory pleasure derived from meat eating itself, focusing on a broad range of sensory qualities:There’s the texture, there’s the smell, there’s aroma, there’s the taste itself … Now imagine if chicken or beef was as soft as paneer, we probably wouldn’t enjoy it as much. There’s a bit of that pull. (Female, age 32)Some discussed adopting a plant-based diet for health-related reasons but also highlighted that the experience, overall, was short of satisfactory:I was doing one week of GM Diet … one day it was full of fruits, then one day it was full of vegetables. And then in the third day, when it was actually the chicken part, frankly speaking even I enjoyed … you just cannot have veggies everyday. (Female, age 35)Only eating veg, I think my whole mouth was, I think gone bad. Because I really wanted to have something … keema [minced meat]. (Female, age 38)Plant-based foods, in comparison to meat-based dishes, were described as “bland”, “boring”, and lacking in the “umami zing”. Even if cooked in the same spices, plant-based foods were still seen to be wanting:you have chicken curry and soya bean curry made from the same masala … but if you replace meat with some other substitutes, you’re gonna be able to tell the difference ... the taste of meat, I feel, is better than the taste of a vegetable. (Male, age 32)The thing is, vegetarian dishes are bland … They don’t get the feeling of the spices in the vegetarian dish ... So when you are eating something juicy, having a bite, it’s a mouthful thing. Vegetarian dishes are not mouthful. (Male, age 25)At the end of a vegetarian meal … I think that maybe [it is] a lack of fullness … I’m eating less because you get bored after a while. (Female, age 32)Tasting the Forbidden FruitIn India, chicken is considered to be widely acceptable, as pork is forbidden to Muslims and beef is prohibited for Hindus (Devi et al.; Jishnu). However, the desire for new flavours seems to be pushing the boundaries of what is deemed acceptable, as highlighted in the discussion below with a 25-year-old male Muslim participant:Participant: When I go out with my friends then I try new things like bacon.Moderator: Bacon?Participant: Yeah... when I went with my colleagues to this restaurant in Bandra—it’s called Saltwater Cafe. And they had this chicken burger with bacon wrapped on it.Moderator: Okay.Participant: And I didn’t know at the time that it’s bacon … They didn’t tell me what we are having … When I had it, I told them that it’s tasting like different, totally different, like I haven’t had this in my life.Moderator: Yeah.Participant: And when they told me that it’s bacon then, I thought, okay fine. Something new I can have. Now I’m old enough to make my own choices.Similarly, several Hindu participants expressed similar sentiments about beef consumption:One of our friends, he used to have beef. He said this tastes better than chicken so I tried it. (Male, age 30)I ended up ordering beef which I actually would never eat ... But then everyone was like, it’s a must try ... So I start off with eating the gravy and then it entices me. That’s when I go and try the meat. (Female, aged 23)Although studies on meat eating in India are limited, it seems that many prefer to consume meats outside the home (Suresh; Devi et al.), away from the watchful eyes of parents, partners and, in some instances, the neighbours:My dad would say if you want to eat beef or anything have it outside but don’t bring it home. (Male, age 29)One of my friends … he keeps secret from his girlfriend … he come with us and eat [meat] and tell us not to tell her. (Male, age 26)People around have a little bit of a different view towards people eating non-veg in that area—so we wouldn’t openly talk about eating non-veg when somebody from the locality is around. (Female, age 32)Further to this point, some discussed a certain thrill that arose from pushing social boundaries by eating these forbidden meats:feel excited ... it gave me confidence also. I didn’t know ... my own decision. Something that is riskier in my life, which I hadn’t done before. (Male, age 25)Meat as a Status SymbolIn urban India, meat is increasingly considered a status symbol (Roy; Esselborn; Goswami). Similarly, several participants highlighted that meat-based dishes tend to be cooked for special occasions:non-vegetarian meals [at home] were perceived as being more elaborate and more lavish probably as compared to vegetarian meals. (Male, age 34)Dal [a lentil dish] is one of the basic things which we don’t make in the house when you have guests, or when you have an occasion … We usually make biryani…gravies of chicken or mutton. (Female, age 38)Success in urban India tends to be measured through one’s engagement with commodities that hold status-enhancing appeal (Mathur), and this also appears to apply to eating practices. Among meat-eating communities, it was found that serving only plant-based foods on special occasions was potentially seen as “low grade” and not quite socially acceptable:It’s just considered not something special. In fact, you would be judged…they would be like, “Oh my God, they only served us vegetables.” (Female, age 32)If you are basically from a Gujarati family, you are helpless. You have to serve that thing [vegetarian food] ... But if you are a non-vegetarian … if you serve them veg, it looks too low grade. (Female, age 38)In fact, among some families, serving “simple vegetarian food” tended to be associated with sombre occasions such as funerals, where one tends to avoid eating certain foods that give rise to desires, such as meat. This is elaborated upon in the below discussion with a Hindu participant (female, aged 40+):Participant: So an aunt of mine passed away a little over a year ago … traditionally we have this 13 day thing where you eat—We call it “Oshoge”… the khaana [food] is supposed to be neutral.Moderator: The khaana is supposed to be vegetarian?Participant: Yeah, it’s not just vegetarian … You’re supposed to have very simple vegetarian food like boiled food or you know dahi [plain yoghurt] and puffed rice … after a day of that, we were all looking at each other and then my cousin said, “Let me teach you how to fillet fish.” Similarly, a Muslim participant mentioned how serving certain dishes—such as dal, a common vegetarian dish—tends to be reserved for funeral occasions and is therefore considered socially unacceptable for other occasions:I’m calling a guest and I make dal chawal [lentils and rice] okay? They will think, arrey yeh kya yeh mayat ka khaana hai kya? [oh what is this, is the food for a corpse or what]? ... I can make it on that particular day when somebody has died in the family ... but then whenever guest is at home, or there is an occasion, we cannot make dal. (Female, age 38)ConclusionUrban India is experiencing a shift in norms around food choices, as meat-based dishes appear to have become symbolic of the broader changing landscape. Meat is not only eaten for its sensory properties but also because of its sociocultural associations. In comparison, many plant-based foods are perceived as relatively bland and uninteresting. This raises the question of how to make plant-based eating more appealing, both in terms of social significance and sensory enjoyment. In view of the attachment to familiar customs against the backdrop of a rapidly changing urban culture (Sinha; Venkatesh), perhaps plant-based foods could be re-introduced to the urban Indian as a blend of Western novelty and traditional familiarity (Majumdar), thereby representing the “the new along with the old” (Sinha 18), and hence enhancing their status. Given the growing body of research calling for a global shift to a heavily plant-based diet for reasons of health and sustainability (Hertwich et al.; Willett et al.), it is clearly important for future research to examine how to best encourage sustainable consumption via an emphasis on plant-based eating in both the developed world, where meat consumption is currently high, and in the developing world, where meat consumption is rising slowly in some countries—such as India—and more rapidly in others, such as China, Brazil and parts of Sub-Saharan Africa (FAOSTAT).ReferencesBansal, Samarth. “More Indians Eating Beef, Buffalo Meat.” The Hindu 29 Oct. 2016. 29 Mar. 2019 <http://www.thehindu.com/news/national/’More-Indians-eating-beef-buffalo-meat’/article16085248.ece>.Census of India.

IntroductionTasmania hangs from the map of Australia like a drop in freefall from the substance of the mainland. Often the whole state is mislaid from Australian maps and logos (Reddit). Tasmania has, at least since federation, been considered peripheral—a region seen as isolated, a ‘problem’ economically, politically, and culturally. However, Tasmania not only cleaves to the ‘north island’ of Australia but is also subject to the gravitational pull of an even greater land mass—Antarctica. In this article, we upturn the political conventions of map-making that place both Antarctica and Tasmania in obscure positions at the base of the globe. We show how a changing global climate re-frames Antarctica and the Southern Ocean as key drivers of worldwide environmental shifts. The liquid and solid water between Tasmania and Antarctica is revealed not as a homogenous barrier, but as a dynamic and relational medium linking the Tasmanian archipelago with Antarctica. When Antarctica becomes the focus, the script is flipped: Tasmania is no longer on the edge, but core to a network of gateways into the southern land. The state’s capital of Hobart can from this perspective be understood as an “Antarctic city”, central to the geopolitics, economy, and culture of the frozen continent (Salazar et al.). Viewed from the south, we argue, Tasmania is not a problem, but an opportunity for a form of ecological, cultural, economic, and political sustainability that opens up the southern continent to science, discovery, and imagination.A Centre at the End of the Earth? Tasmania as ParadoxThe islands of Tasmania owe their existence to climate change: a period of warming at the end of the last ice age melted the vast sheets of ice covering the polar regions, causing sea levels to rise by more than one hundred metres (Tasmanian Climate Change Office 8). Eleven thousand years ago, Aboriginal people would have witnessed the rise of what is now called Bass Strait, turning what had been a peninsula into an archipelago, with the large island of Tasmania at its heart. The heterogeneous practices and narratives of Tasmanian regional identity have been shaped by the geography of these islands, and their connection to the Southern Ocean and Antarctica. Regions, understood as “centres of collective consciousness and sociospatial identities” (Paasi 241) are constantly reproduced and reimagined through place-based social practices and communications over time. As we will show, diverse and contradictory narratives of Tasmanian regionality often co-exist, interacting in complex and sometimes complementary ways. Ecocritical literary scholar C.A. Cranston considers duality to be embedded in the textual construction of Tasmania, writing “it was hell, it was heaven, it was penal, it was paradise” (29). Tasmania is multiply polarised: it is both isolated and connected; close and far away; rich in resources and poor in capital; the socially conservative birthplace of radical green politics (Hay 60). The weather, as if sensing the fine balance of these paradoxes, blows hot and cold at a moment’s notice.Tasmania has wielded extraordinary political influence at times in its history—notably during the settlement of Melbourne in 1835 (Boyce), and during protests against damming the Franklin River in the early 1980s (Mercer). However, twentieth-century historical and political narratives of Tasmania portray the Bass Strait as a barrier, isolating Tasmanians from the mainland (Harwood 61). Sir Bede Callaghan, who headed one of a long line of federal government inquiries into “the Tasmanian problem” (Harwood 106), was clear that Tasmania was a victim of its own geography:the major disability facing the people of Tasmania (although some residents may consider it an advantage) is that Tasmania is an island. Separation from the mainland adversely affects the economy of the State and the general welfare of the people in many ways. (Callaghan 3)This perspective may stem from the fact that Tasmania has maintained the lowest Gross Domestic Product per capita of all states since federation (Bureau of Infrastructure Transport and Regional Economics 9). Socially, economically, and culturally, Tasmania consistently ranks among the worst regions of Australia. Statistical comparisons with other parts of Australia reveal the population’s high unemployment, low wages, poor educational outcomes, and bad health (West 31). The state’s remoteness and isolation from the mainland states and its reliance on federal income have contributed to the whole of Tasmania, including Hobart, being classified as ‘regional’ by the Australian government, in an attempt to promote immigration and economic growth (Department of Infrastructure and Regional Development 1). Tasmania is indeed both regional and remote. However, in this article we argue that, while regionality may be cast as a disadvantage, the island’s remote location is also an asset, particularly when viewed from a far southern perspective (Image 1).Image 1: Antarctica (Orthographic Projection). Image Credit: Wikimedia Commons, Modified Shading of Tasmania and Addition of Captions by H. Nielsen.Connecting Oceans/Collapsing DistanceTasmania and Antarctica have been closely linked in the past—the future archipelago formed a land bridge between Antarctica and northern land masses until the opening of the Tasman Seaway some 32 million years ago (Barker et al.). The far south was tangible to the Indigenous people of the island in the weather blowing in from the Southern Ocean, while the southern lights, or “nuyina”, formed a visible connection (Australia’s new icebreaker vessel is named RSV Nuyina in recognition of these links). In the contemporary Australian imagination, Tasmania tends to be defined by its marine boundaries, the sea around the islands represented as flat, empty space against which to highlight the topography of its landscape and the isolation of its position (Davies et al.). A more relational geographic perspective illuminates the “power of cross-currents and connections” (Stratford et al. 273) across these seascapes. The sea country of Tasmania is multiple and heterogeneous: the rough, shallow waters of the island-scattered Bass Strait flow into the Tasman Sea, where the continental shelf descends toward an abyssal plain studded with volcanic seamounts. To the south, the Southern Ocean provides nutrient-rich upwellings that attract fish and cetacean populations. Tasmania’s coast is a dynamic, liminal space, moving and changing in response to the global currents that are driven by the shifting, calving and melting ice shelves and sheets in Antarctica.Oceans have long been a medium of connection between Tasmania and Antarctica. In the early colonial period, when the seas were the major thoroughfares of the world and inland travel was treacherous and slow, Tasmania’s connection with the Southern Ocean made it a valuable hub for exploration and exploitation of the south. Between 1642 and 1900, early European explorers were followed by British penal colonists, convicts, sealers, and whalers (Kriwoken and Williamson 93). Tasmania was well known to polar explorers, with expeditions led by Jules Dumont d’Urville, James Clark Ross, Roald Amundsen, and Douglas Mawson all transiting through the port of Hobart. Now that the city is no longer a whaling hub, growing populations of cetaceans continue to migrate past the islands on their annual journeys from the tropics, across the Sub-Antarctic Front and Antarctic circumpolar current, and into the south polar region, while southern species such as leopard seals are occasionally seen around Tasmania (Tasmania Parks and Wildlife). Although the water surrounding Tasmania and Antarctica is at times homogenised as a ‘barrier’, rendering these places isolated, the bodies of water that surround both are in fact permeable, and regularly crossed by both humans and marine species. The waters are diverse in their physical characteristics, underlying topography, sea life, and relationships, and serve to connect many different ocean regions, ecosystems, and weather patterns.Views from the Far SouthWhen considered in terms of its relative proximity to Antarctic, rather than its distance from Australia’s political and economic centres, Tasmania’s identity undergoes a significant shift. A sign at Cockle Creek, in the state’s far south, reminds visitors that they are closer to Antarctica than to Cairns, invoking a discourse of connectedness that collapses the standard ten-day ship voyage to Australia’s closest Antarctic station into a unit comparable with the routinely scheduled 5.5 hour flight to North Queensland. Hobart is the logistical hub for the Australian Antarctic Division and the French Institut Polaire Francais (IPEV), and has hosted Antarctic vessels belonging to the USA, South Korea, and Japan in recent years. From a far southern perspective, Hobart is not a regional Australian capital but a global polar hub. This alters the city’s geographic imaginary not only in a latitudinal sense—from “top down” to “bottom up”—but also a longitudinal one. Via its southward connection to Antarctica, Hobart is also connected east and west to four other recognized gateways: Cape Town in South Africa, Christchurch in New Zealand; Punta Arenas in Chile; and Ushuaia in Argentina (Image 2). The latter cities are considered small by international standards, but play an outsized role in relation to Antarctica.Image 2: H. Nielsen with a Sign Announcing Distances between Antarctic ‘Gateway’ Cities and Antarctica, Ushuaia, Argentina, 2018. Image Credit: Nicki D'Souza.These five cities form what might be called—to adapt geographer Klaus Dodds’ term—a ‘Southern Rim’ around the South Polar region (Dodds Geopolitics). They exist in ambiguous relationship to each other. Although the five cities signed a Statement of Intent in 2009 committing them to collaboration, they continue to compete vigorously for northern hemisphere traffic and the brand identity of the most prominent global gateway. A state government brochure spruiks Hobart, for example, as the “perfect Antarctic Gateway” emphasising its uniqueness and “natural advantages” in this regard (Tasmanian Government, 2016). In practice, the cities are automatically differentiated by their geographic position with respect to Antarctica. Although the ‘ice continent’ is often conceived as one entity, it too has regions, in both scientific and geographical senses (Terauds and Lee; Antonello). Hobart provides access to parts of East Antarctica, where the Australian, French, Japanese, and Chinese programs (among others) have bases; Cape Town is a useful access point for Europeans going to Dronning Maud Land; Christchurch is closest to the Ross Sea region, site of the largest US base; and Punta Arenas and Ushuaia neighbour the Antarctic Peninsula, home to numerous bases as well as a thriving tourist industry.The Antarctic sector is important to the Tasmanian economy, contributing $186 million (AUD) in 2017/18 (Wells; Gutwein; Tasmanian Polar Network). Unsurprisingly, Tasmania’s gateway brand has been actively promoted, with the 2016 Australian Antarctic Strategy and 20 Year Action Plan foregrounding the need to “Build Tasmania’s status as the premier East Antarctic Gateway for science and operations” and the state government releasing a “Tasmanian Antarctic Gateway Strategy” in 2017. The Chinese Antarctic program has been a particular focus: a Memorandum of Understanding focussed on Australia and China’s Antarctic relations includes a “commitment to utilise Australia, including Tasmania, as an Antarctic ‘gateway’.” (Australian Antarctic Division). These efforts towards a closer relationship with China have more recently come under attack as part of a questioning of China’s interests in the region (without, it should be noted, a concomitant questioning of Australia’s own considerable interests) (Baker 9). In these exchanges, a global power and a state of Australia generally classed as regional and peripheral are brought into direct contact via the even more remote Antarctic region. This connection was particularly visible when Chinese President Xi Jinping travelled to Hobart in 2014, in a visit described as both “strategic” and “incongruous” (Burden). There can be differences in how this relationship is narrated to domestic and international audiences, with issues of sovereignty and international cooperation variously foregrounded, laying the ground for what Dodds terms “awkward Antarctic nationalism” (1).Territory and ConnectionsThe awkwardness comes to a head in Tasmania, where domestic and international views of connections with the far south collide. Australia claims sovereignty over almost 6 million km2 of the Antarctic continent—a claim that in area is “roughly the size of mainland Australia minus Queensland” (Bergin). This geopolitical context elevates the importance of a regional part of Australia: the claims to Antarctic territory (which are recognised only by four other claimant nations) are performed not only in Antarctic localities, where they are made visible “with paraphernalia such as maps, flags, and plaques” (Salazar 55), but also in Tasmania, particularly in Hobart and surrounds. A replica of Mawson’s Huts in central Hobart makes Australia’s historic territorial interests in Antarctica visible an urban setting, foregrounding the figure of Douglas Mawson, the well-known Australian scientist and explorer who led the expeditions that proclaimed Australia’s sovereignty in the region of the continent roughly to its south (Leane et al.). Tasmania is caught in a balancing act, as it fosters international Antarctic connections (such hosting vessels from other national programs), while also playing a key role in administering what is domestically referred to as the Australian Antarctic Territory. The rhetoric of protection can offer common ground: island studies scholar Godfrey Baldacchino notes that as island narratives have moved “away from the perspective of the ‘explorer-discoverer-colonist’” they have been replaced by “the perspective of the ‘custodian-steward-environmentalist’” (49), but reminds readers that a colonising disposition still lurks beneath the surface. It must be remembered that terms such as “stewardship” and “leadership” can undertake sovereignty labour (Dodds “Awkward”), and that Tasmania’s Antarctic connections can be mobilised for a range of purposes. When Environment Minister Greg Hunt proclaimed at a press conference that: “Hobart is the gateway to the Antarctic for the future” (26 Apr. 2016), the remark had meaning within discourses of both sovereignty and economics. Tasmania’s capital was leveraged as a way to position Australia as a leader in the Antarctic arena.From ‘Gateway’ to ‘Antarctic City’While discussion of Antarctic ‘Gateway’ Cities often focuses on the economic and logistical benefit of their Antarctic connections, Hobart’s “gateway” identity, like those of its counterparts, stretches well beyond this, encompassing geological, climatic, historical, political, cultural and scientific links. Even the southerly wind, according to cartoonist Jon Kudelka, “has penguins in it” (Image 3). Hobart residents feel a high level of connection to Antarctica. In 2018, a survey of 300 randomly selected residents of Greater Hobart was conducted under the umbrella of the “Antarctic Cities” Australian Research Council Linkage Project led by Assoc. Prof. Juan Francisco Salazar (and involving all three present authors). Fourteen percent of respondents reported having been involved in an economic activity related to Antarctica, and 36% had attended a cultural event about Antarctica. Connections between the southern continent and Hobart were recognised as important: 71.9% agreed that “people in my city can influence the cultural meanings that shape our relationship to Antarctica”, while 90% agreed or strongly agreed that Hobart should play a significant role as a custodian of Antarctica’s future, and 88.4% agreed or strongly agreed that: “How we treat Antarctica is a test of our approach to ecological sustainability.” Image 3: “The Southerly” Demonstrates How Weather Connects Hobart and Antarctica. Image Credit: Jon Kudelka, Reproduced with Permission.Hobart, like the other gateways, activates these connections in its conscious place-branding. The city is particularly strong as a centre of Antarctic research: signs at the cruise-ship terminal on the waterfront claim that “There are more Antarctic scientists based in Hobart […] than at any other one place on earth, making Hobart a globally significant contributor to our understanding of Antarctica and the Southern Ocean.” Researchers are based at the Institute for Marine and Antarctic Studies (IMAS), the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the Australian Antarctic Division (AAD), with several working between institutions. Many Antarctic researchers located elsewhere in the world also have a connection with the place through affiliations and collaborations, leading journalist Jo Chandler to assert that “the breadth and depth of Hobart’s knowledge of ice, water, and the life forms they nurture […] is arguably unrivalled anywhere in the world” (86).Hobart also plays a significant role in Antarctica’s governance, as the site of the secretariats for the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and the Agreement on the Conservation of Albatrosses and Petrels (ACAP), and as host of the Antarctic Consultative Treaty Meetings on more than one occasion (1986, 2012). The cultural domain is active, with Tasmanian Museum and Art Gallery (TMAG) featuring a permanent exhibit, “Islands to Ice”, emphasising the ocean as connecting the two places; the Mawson’s Huts Replica Museum aiming (among other things) to “highlight Hobart as the gateway to the Antarctic continent for the Asia Pacific region”; and a biennial Australian Antarctic Festival drawing over twenty thousand visitors, about a sixth of them from interstate or overseas (Hingley). Antarctic links are evident in the city’s natural and built environment: the dolerite columns of Mt Wellington, the statue of the Tasmanian Antarctic explorer Louis Bernacchi on the waterfront, and the wharfs that regularly accommodate icebreakers such as the Aurora Australis and the Astrolabe. Antarctica is figured as a southern neighbour; as historian Tom Griffiths puts it, Tasmanians “grow up with Antarctica breathing down their necks” (5). As an Antarctic City, Hobart mediates access to Antarctica both physically and in the cultural imaginary.Perhaps in recognition of the diverse ways in which a region or a city might be connected to Antarctica, researchers have recently been suggesting critical approaches to the ‘gateway’ label. C. Michael Hall points to a fuzziness in the way the term is applied, noting that it has drifted from its initial definition (drawn from economic geography) as denoting an access and supply point to a hinterland that produces a certain level of economic benefits. While Hall looks to keep the term robustly defined to avoid empty “local boosterism” (272–73), Gabriela Roldan aims to move the concept “beyond its function as an entry and exit door”, arguing that, among other things, the local community should be actively engaged in the Antarctic region (57). Leane, examining the representation of Hobart as a gateway in historical travel texts, concurs that “ingress and egress” are insufficient descriptors of Tasmania’s relationship with Antarctica, suggesting that at least discursively the island is positioned as “part of an Antarctic rim, itself sharing qualities of the polar region” (45). The ARC Linkage Project described above, supported by the Hobart City Council, the State Government and the University of Tasmania, as well as other national and international partners, aims to foster the idea of the Hobart and its counterparts as ‘Antarctic cities’ whose citizens act as custodians for the South Polar region, with a genuine concern for and investment in its future.Near and Far: Local Perspectives A changing climate may once again herald a shift in the identity of the Tasmanian islands. Recognition of the central role of Antarctica in regulating the global climate has generated scientific and political re-evaluation of the region. Antarctica is not only the planet’s largest heat sink but is the engine of global water currents and wind patterns that drive weather patterns and biodiversity across the world (Convey et al. 543). For example, Tas van Ommen’s research into Antarctic glaciology shows the tangible connection between increased snowfall in coastal East Antarctica and patterns of drought southwest Western Australia (van Ommen and Morgan). Hobart has become a global centre of marine and Antarctic science, bringing investment and development to the city. As the global climate heats up, Tasmania—thanks to its low latitude and southerly weather patterns—is one of the few regions in Australia likely to remain temperate. This is already leading to migration from the mainland that is impacting house prices and rental availability (Johnston; Landers 1). The region’s future is therefore closely entangled with its proximity to the far south. Salazar writes that “we cannot continue to think of Antarctica as the end of the Earth” (67). Shifting Antarctica into focus also brings Tasmania in from the margins. As an Antarctic city, Hobart assumes a privileged positioned on the global stage. This allows the city to present itself as central to international research efforts—in contrast to domestic views of the place as a small regional capital. The city inhabits dual identities; it is both on the periphery of Australian concerns and at the centre of Antarctic activity. Tasmania, then, is not in freefall, but rather at the forefront of a push to recognise Antarctica as entangled with its neighbours to the north.AcknowledgementsThis work was supported by the Australian Research Council under LP160100210.ReferencesAntonello, Alessandro. “Finding Place in Antarctica.” Antarctica and the Humanities.

Introduction Ever-enduring advancements in science and technology promise to offer solutions to problems or simply to make life a bit easier. However, not every advancement has only positive effects, but can also have undesired, negative ramifications. This article will take a closer look at Deus Ex: Human Revolution (DXHR), a dystopian video game which promises to put players in the position of deciding whether the science of human enhancement is a way to try to play God, or whether it enables us “to become the Gods we’ve always been striving to be” (Eidos Montreal, “Deus Ex: Human Revolution”). In this article I will argue that DXHR creates a space in which players can virtually witness future technologies for human performance enhancement without the need to alter their own bodies. DXHR is special particularly in two respects: first, the developers have achieved a high credibility and scientific realism of the enhancement technologies depicted in the game which can be described as being “diegetic prototypes” (Kirby, “The Future Is Now ” 43); second, the game directly invites players to reflect upon the impact and morality of human enhancement. It does so through a story in line with the cyberpunk genre, which envisions not only the potential benefits of an emergent technology, but has an even stronger focus on the negative contingencies. The game and its developers foresee a near-future society that is split into two fractions due to human enhancement technologies which come in the form of neuro-implants and mechanical prosthetics; and they foresee a near-future setting in which people are socially and economically forced to undergo enhancement surgery in order to keep up with the augmented competition. DXHR is set in the year 2027 and the player takes control of Adam Jensen, an ex-SWAT police officer who is now the chief of security of Sarif Industries, one of the world's leading biotechnology companies that produce enhancement technologies. Augmented terrorists attack Sarif Industries, abduct the head scientists, and nearly kill Jensen. Jensen merely survives because his boss puts him through enhancement surgery, which replaces many parts of his body with mechanical augmentations. In the course of the game it becomes clear that Jensen has been augmented beyond any life-saving necessity that grants him superhuman abilities and allows him to find and defeat the terrorists, but the augmentations also challenge his humanity. Is Jensen a human, a cyborg, or has he become more machine than man? DXHR grants players the illusion of immersion into a virtual world in which augmentations exist as a matter of fact and in which a certain level of control can be practiced. Players take up the role of a character distinctly more powerful and capable than the person in control, exceeding the limits of human abilities. The superior abilities are a result of scientific and technological advancements implying that every man or woman is able to attain the same abilities by simply acquiring augmentations. Thus, with the help of the playable character, Adam Jensen, the game lets players experience augmentations without any irreparable damages done to their bodies, but the experience will leave a lasting impression on players regarding the science of human enhancement. The experience with augmentations happens through and benefits from the effect of “virtual witnessing”: The technology of virtual witnessing involves the production in a reader’s mind of such an image of an experimental scene as obviates the necessity for either direct witness or replication. Through virtual witnessing the multiplication of witnesses could be, in principle, unlimited. (Shapin and Schaffer 60) In other words, simply by reading about and/or seeing scientific advancements, audiences can witness them without having to be present at the site of creation. The video game, hereby, is itself the medium of virtual witnessing whereby audiences can experience scientific advancements. Nevertheless, the video game is not just about reading or seeing potential future enhancement technologies, but permits players to virtually test-drive augmentations—to actually try out three-dimensionally rendered prototypes on a virtual body. In order to justify this thesis, a couple of things need to be clarified that explain in which ways the virtual witnessing of fictional enhancements in DXHR is a valid claim. Getting into the Game First I want to briefly describe how I investigated the stated issue. I have undertaken an auto-ethnography (Ellis, Adams, and Bochner) of DXHR, which concretely means that I have analytically played DXHR in an explorative fashion (Aarseth) trying to discover as many elements on human enhancement that the game has to offer. This method requires not only close observation of the virtual environment and documentation through field notes and screenshots, but also self-reflection of the actions that I chose to take and that were offered to me in the course of the game. An essential part of analytically playing a game is to be aware that the material requires “the activity of an actual player in order to be accessible for scrutiny” (Iversen), and that the player’s input fundamentally shapes the gaming experience (Juul 42). The meaning of the game is contingent upon the contribution of the player, especially in times in which digital games grant players more and more freedom in terms of narrative construction. In contrast to traditional narrative, the game poses an active challenge to the player which entails the need to become better in relation to the game’s mechanics and hence “studying games … implies interacting with the game rules and exploring the possibilities created by these rules, in addition to studying the graphical codes or the narration that unfolds” (Malliet). It is important to highlight that, although the visual representation of human enhancement technologies has an enormous potential impact on the player’s experience, it is not the only crucial element. Next to the representational shell, the core of the game, i.e. “how game rules and interactions with game objects and other players are structured” (Mäyrä 165), shapes the virtual witnessing of the augmentations in just an important way. Finally, the empirical material that was collected was analyzed and interpreted with the help of close-reading (Bizzocchi and Tanenbaum 395). In addition to the game itself, I have enriched my empirical material with interviews of developers of the game that are partly freely available on the Internet, and with the promotional material such as the trailers and a website (Eidos Montreal, “Sarif Industries”) that was released prior to the game. Sociotechnical Imaginaries In this case study of DXHR I have not only investigated how augmented bodies and enhancement technologies are represented in this specific video game, but also attempted to uncover which “sociotechnical imaginaries” (Jasanoff and Kim) underlie the game and support the virtual witnessing experience. Sociotechnical imaginaries are defined as “collectively imagined forms of social life and social order reflected in the design and fulfillment of nation-specific scientific and/or technological projects” (Jasanoff and Kim 120). The concept appeared to be suitable for this study as it covers and includes “promises, visions and expectations of future possibilities” (Jasanoff and Kim 122) of a technology as well as “implicit understandings of what is good or desirable in the social world writ large” (Jasanoff and Kim 122–23). The game draws upon several imaginaries of human enhancement. For example, the most basic imaginary in the game is that advanced engineered prosthetics and implants will be able to not only remedy dysfunctional parts of the human body, but will be able to upgrade these. Apart from this idea, the two prevailing sociotechnical imaginaries that forward the narrative can be subsumed as the transhumanist and the purist imaginary. The latter views human enhancement, with the help of science and technology, as unnatural and as a threat to humanity particularly through the power that it grants to individuals, while the former transports the opposing view. Transhumanism is: the intellectual and cultural movement that affirms the possibility and desirability of fundamentally improving the human condition through applied reason, especially by developing and making widely available technologies to eliminate aging and to greatly enhance human intellectual, physical, and psychological capacities. (Chrislenko et al.) The transhumanist imaginary in the game views technological development of the body as another step in the human evolution, not as something abhorrent to nature, but a fundamental human quality. Similar ideas can be found in the writings of Sigmund Freud and Arnold Gehlen, who both view the human being’s need to improve as part of its culture. Gehlen described the human as a “Mängelwesen”—a ‘deficient’ creature—who is, in contrast to other species, not specialized to a specific environment, but has the ability to adapt to nearly every situation because of this deficiency (Menne, Trutwin, and Türk). Freud even denoted the human as a “Prothesengott”—a god of prostheses: By means of all his tools, man makes his own organs more perfect—both the motor and the sensory—or else removes the obstacles in the way of their activity. Machinery places gigantic power at his disposal which, like his muscles, he can employ in any direction; ships and aircraft have the effect that neither air nor water can prevent his traversing them. With spectacles he corrects the defects of the lens in his own eyes; with telescopes he looks at far distances; with the microscope he overcomes the limitations in visibility due to the structure of his retina. (Freud 15) Returning to DXHR, how do the sociotechnical imaginaries matter for the player? Primarily, the imaginaries cannot be avoided as they pervade nearly every element in the game, from the main story that hinges upon human enhancement over the many optional side missions, to contextual elements such as a conference on “the next steps in human evolution” (Eidos Montreal, “Deus Ex: Human Revolution”). Most importantly, it impacts the player’s view in a crucial way. Human enhancement technologies are presented as controversial, neither exclusively good nor bad, which require reflection and perhaps even legal regulation. In this way, DXHR can be seen as offering the player a restricted building set of sociotechnical imaginaries of human enhancement, whereby the protagonist, Adam Jensen, becomes the player’s vessel to construct one’s own individual imaginary. In the end the player is forced to choose one of four outcomes to complete the game, and this choice can be quite difficult to make. Anticipation of the Future It is not unusual for video games to feature futuristic technologies that do not exist in the real world, but what makes DXHR distinct from others is that the developers have included an extent of information that goes beyond any game playing necessity (see Figures 1 & 2). Moreover, the information is not fictional but the developers have taken strategic steps to make it credible. Mary DeMarle, the narrative designer, explained at the San Diego Comic-Con in 2011, that a timeline of augmentation was created during the production phase in which the present state of technology was extrapolated into the future. In small incremental steps the developers have anticipated which enhancement technologies might be potentially feasible by the year 2027. Their efforts were supported by the science consultant, Will Rosellini, who voluntarily approached the development team to help. Being a neuroscientist, he could not have been a more fitting candidate for the job as he is actively working and researching in the biotechnology sector. He has co-founded two companies, MicroTransponder Inc., which produces tiny implantable wireless devices to interface with the nervous system to remedy diseases (see Rosellini’s presentation at the 2011 Comic-Con) and Rosellini Scientific, which funds, researches and develops advanced technological healthcare solutions (Rosellini; Rosellini Scientific). Due to the timeline which has been embedded explicitly and implicitly, no augmentation appears as a disembodied technology without history in the game. For example, although the protagonist wears top-notch military arm prostheses that appear very human-like, this prosthesis is depicted as one of the latest iterations and many non-playable characters possess arm prostheses that appear a lot older, cruder and more industrial than those of Jensen. Furthermore, an extensive description employing scientific jargon for each of the augmentations can be read on the augmentation overview screen, which includes details about the material composition and bodily locations of the augmentations. Figure 1: More Info Section of the Cybernetic Arm Prosthesis as it appears in-game (all screenshots taken with permission from Deus Ex: Human Revolution (2011), courtesy of Eidos Montreal) More details are provided through eBooks, which are presented in the form of scientific articles or conference proceedings, for which the explorative gamer is also rewarded with valuable experience points upon finding which are used to activate and upgrade augmentations. The eBooks also reflect the timeline as each eBook is equipped with a year of publication between 2001 and 2022. Despite the fact that these articles have been supposedly written by a fictional character, the information is authentic and taken from actual scientific research papers, whereby some of these articles even include a proper scientific citation. Figure 2: Example of a Darrow eBook The fact that a scientist was involved in the production of the game allows classifying the augmentations as “diegetic prototypes” which are “cinematic depictions of future technologies … that demonstrate to large public audiences a technology’s need, benevolence and viability” (“The Future Is Now” 43). Diegetic prototypes are fictional, on-screen depictions of technologies that do not exist in that form in real life and have been created with the help of a science consultant. They have been placed in movies to allay anxieties and doubts and perhaps to even provoke a longing in audiences to see depicted technologies become reality (Kirby, “The Future Is Now” 43). Of course the aesthetic appearance of the prototypes has an impact on audiences’s desire, and particularly the artificial arms of Jensen that have been designed in an alluring fashion as can be seen in the following figure: Figure 3: Adam Jensen and arm prosthesis An important fact about diegetic prototypes—and about prototypes (see Suchman, Trigg, and Blomberg) in general—is that they are put to specific use and are embedded and presented in an identifiable social context. Technological objects in cinema are at once both completely artificial—all aspects of their depiction are controlled—and normalized as practical objects. Characters treat these technologies as a ‘natural’ part of their landscape and interact with these prototypes as if they are everyday parts of their world. … fictional characters are ‘socializing’ technological artifacts by creating meanings for the audience, ‘which is tantamount to making the artifacts socially relevant’. (Kirby, “Lab Coats” 196) The power of DXHR is that the diegetic prototypes—the augmentations—are not only based on real world scientific developments and contextualized in a virtual social space, but that the player has the opportunity to handle the augmentations. Virtual Testing Virtual witnessing of the not-yet-existent augmentations is supported by scientific descriptions, articles, and the appearance of the technologies in DXHR, but the moral and ethical engagement is established by the player’s ability to actively use the augmentations and by the provision of choice how to use them. As mentioned, most of the augmentations are inactive and must first be activated by accumulating and spending experience points on them. This requires the player to make reflections on the potential usage and how a particular augmentation will lead to the successful completion of a mission. This means that the player has to constantly decide how s/he wants to play the game. Do I want to be able to hack terminals and computers or do I rather prefer getting mission-critical information by confronting people in conversation? Do I want to search for routes where I can avoid enemy detection or do I rather prefer taking the direct route through the enemy lines with heavy guns in hands? This recurring reflection of which augmentation to choose and their continuous usage throughout the game causes the selected augmentations to become valuable and precious to the player because they transform from augmentations into frequently used tools that facilitate challenge and reduce difficulty of certain situations. In addition, the developers have ensured that no matter which approach is taken, it will always lead to success. This way the role-playing elements of the game are accentuated and each player will construct their own version of Jensen. However, it may be argued that DXHR goes beyond mere character building. There is a breadth of information and opinions on human enhancement offered, but also choices that are made invite players to reflect upon the topic of human enhancement. Among the most conspicuous instances in the game, that involve the player’s choice, are the conversations with other non-playable characters. These are events in the game which require the player to choose one out of three responses for Jensen, and hence, these determine to some extent Jensen’s attitude towards human enhancement. Thus, in the course of the game players might discover their own conviction and might compose their own imaginary of human enhancement. Conclusion This article has explored that DXHR enables players to experience augmentations without being modified themselves. The game is filled with various sociotechnical imaginaries of prosthetic and neurological human enhancement technologies. The relevance of these imaginaries is increased by a high degree of credibility as a science consultant has ensured that the fictional augmentations are founded upon real world scientific advancements. The main story, and much of the virtual world, hinge upon the existence and controversy of these sorts of technologies. Finally, the medium ‘videogame’ allows taking control of an individual, who is heavily augmented with diegetic prototypes of future enhancement technologies, and it also allows using and testing the increased abilities in various situations and challenges. All these elements combined enable players to virtually witness not-yet-existent, future augmentations safely in the present without the need to undertake any alterations of their own bodies. This, in addition to the fact that the technologies are depicted in an appealing fashion, may create a desire in players to see these augmentations become reality. Nevertheless, DXHR sparks an important incentive to critically think about the future of human enhancement technologies.References Aarseth, Espen. “Playing Research: Methodological Approaches to Game Analysis.” DAC Conference, Melbourne, 2003. 14 Apr. 2013 ‹http://hypertext.rmit.edu.au/dac/papers/Aarseth.pdf›.

Introduction Negative stereotyping of alternative diets such as veganism and other plant-based diets has been common in Australia, conventionally a meat-eating culture (OECD qtd. in Ting). Indeed, meat consumption in Australia is sanctioned by the ubiquity of advertising linking meat-eating to health, vitality and nation-building, and public challenges to such plant-based diets as veganism. In addition, state, commercial enterprises, and various community groups overtly resist challenges to Australian meat-eating norms and to the intensive animal husbandry practices that underpin it. Hence activists, who may contest not simply this norm but many of the customary industry practices that comprise Australia’s meat production, have been accused of promoting a vegan agenda and even of undermining the “Australian way of life”.If veganism meansa philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals. (Vegan Society)then our interest in this article lies in how a stereotyped label of veganism (and other associated attributes) is being used across Australian public spheres to challenge the work of animal activists as they call out factory farming for entrenched animal cruelty. This is carried out in three main parts. First, following an outline of our research approach, we examine the processes of stereotyping and the key dimensions of vegan stereotyping. Second, in the main part of the article, we reveal how opponents to such animal activist organisations as Animals Australia attempt to undermine activist calls for change by framing them as promoting an un-Australian vegan agenda. Finally, we consider how, despite such framing, that organisation is generating productive public debate around animal welfare, and, further, facilitating the creation of new activist identifications and identities.Research ApproachData collection involved searching for articles where Animals Australia and animal activism were yoked with veg*n (vegan and vegetarian), across the period May 2011 to 2016 (discussion peaked between May and June 2013). This period was of interest because it exposed a flare point with public discord being expressed between communities—namely between rural and urban consumers, farmers and animal activists, Coles Supermarkets (identified by The Australian Government the Treasury as one of two major supermarkets holding over 65% share of Australian food retail market) and their producers—and a consequent voicing of disquiet around Australian identity. We used purposive sampling (Waller, Farquharson, and Dempsey 67) to identify relevant materials as we knew in advance the case was “information-rich” (Patton 181) and would provide insightful information about a “troublesome” phenomenon (Emmel 6). Materials were collected from online news articles (30) and readers’ comments (167), online magazines (2) and websites (2) and readers’ comments (3), news items (Factiva 13), Australian Broadcasting Commission television (1) and radio (1), public blogs (2), and Facebook pages from involved organisations, specifically Australia’s National Farmers’ Federation (NFF, 155 posts) and Coles Supermarkets (29 posts). Many of these materials were explicitly responsive to a) Animals Australia’s Make It Possible campaign against Australian factory farming (launched and highly debated during this period), and b) Coles Supermarket’s short-lived partnership with Animals Australia in 2013. We utilised content analysis so as to make visible the most prominent and consistent stereotypes utilised in these various materials during the identified period. The approach allowed us to code and categorise materials so as to determine trends and patterns of words used, their relationships, and key structures and ways of speaking (Weerakkody). In addition, discourse analysis (Gee) was used in order to identify and track “language-in-use” so as to make visible the stereotyping deployed during the public reception of both the campaign and Animals Australia’s associated partnership with Coles. These methods enabled a “nuanced approach” (Coleman and Moss 12) with which to spot putdowns, innuendos, and stereotypical attitudes.Vegan StereotypingStereotypes creep into everyday language and are circulated and amplified through mainstream media, speeches by public figures, and social media. Stereotypes maintain their force through being reused and repurposed, making them difficult to eradicate due to their “cumulative effects” and influence (Harris and Sanborn 38; Inzlicht, Tullett, Legault, and Kang; Pickering). Over time stereotypes can become the lens through which we view “the world and social reality” (Harris and Sanborn 38; Inzlicht et al.). In summation, stereotyping:reduces identity categories to particular sets of deeds, attributes and attitudes (Whitley and Kite);informs individuals’ “cognitive investments” (Blum 267) by associating certain characteristics with particular groups;comprises symbolic and connotative codes that carry sets of traits, deeds, or beliefs (Cover; Rosello), and;becomes increasingly persuasive through regulating language and image use as well as identity categories (Cover; Pickering; Rosello).Not only is the “iterative force” (Rosello 35) of such associative stereotyping compounded due to its dissemination across digital media sites such as Facebook, YouTube, websites, and online news, but attempts to denounce it tend to increase its “persuasive power” (29). Indeed, stereotypes seem to refuse “to die” (23), remaining rooted in social and cultural memory (Whitley and Kite 10).As such, despite the fact that there is increasing interest in Australia and elsewhere in new food norms and plant-based diets (see, e.g., KPMG), as well as in vegan lifestyle options (Wright), studies still show that vegans remain a negatively stereotyped group. Previous studies have suggested that vegans mark a “symbolic threat” to Western, conventionally meat-eating cultures (MacInnis and Hodson 722; Stephens Griffin; Cole and Morgan). One key UK study of national newspapers, for instance, showed vegans continuing to be discredited in multiple ways as: 1) “self-evidently ridiculous”; 2) “ascetics”; 3) having a lifestyle difficult and impossible to maintain; 4) “faddist”; 5) “oversensitive”; and 6) “hostile extremists” (Cole and Morgan 140–47).For many Australians, veganism also appears anathema to their preferred culture and lifestyle of meat-eating. For instance, the NFF, Meat & Livestock Australia (MLA), and other farming bodies continue to frame veganism as marking an extreme form of lifestyle, as anti-farming and un-Australian. Such perspectives are also circulated through online rural news and readers’ comments, as will be discussed later in the article. Such representations are further exemplified by the MLA’s (Lamb, Australia Day, Celebrate Australia) Australia Day lamb advertising campaigns (Bembridge; Canning). For multiple consecutive years, the campaign presented vegans (and vegetarians) as being self-evidently ridiculous and faddish, representing them as mentally unhinged and fringe dwellers. Such stereotyping not only invokes “affective reactions” (Whitley and Kite 8)—including feelings of disgust towards individuals living such lifestyles or holding such values—but operates as “political baits” (Rosello 18) to shore-up or challenge certain social or political positions.Although such advertisements are arguably satirical, their repeated screening towards and on Australia Day highlights deeply held views about the normalcy of animal agriculture and meat-eating, “homogenizing” (Blum 276; Pickering) both meat-eaters and non-meat-eaters alike. Cultural stereotyping of this kind amplifies “social” as well as political schisms (Blum 276), and arguably discourages consumers—whether meat-eaters or non-meat-eaters—from advocating together around shared goals such as animal welfare and food safety. Additionally, given the rise of new food practices in Australia—including flexitarian, reducetarian, pescatarian, kangatarian (a niche form of ethical eating), vegivores, semi-vegetarian, vegetarian, veganism—alongside broader commitments to ethical consumption, such stereotyping suggests that consumers’ actual values and preferences are being disregarded in order to shore-up the normalcy of meat-eating.Animals Australia and the (So-Called) Vegan Agenda of Animal ActivismGiven these points, it is no surprise that there is a tacit belief in Australia that anyone labelled an animal activist must also be vegan. Within this context, we have chosen to primarily focus on the attitudes towards the campaigning work of Animals Australia—a not-for-profit organisation representing some 30 member groups and over 2 million individual supporters (Animals Australia, “Who Is”)—as this organisation has been charged as promoting a vegan agenda. Along with the RSPCA and Voiceless, Animals Australia represents one of the largest animal protection organisations within Australia (Chen). Its mission is to:Investigate, expose and raise community awareness of animal cruelty;Provide animals with the strongest representation possible to Government and other decision-makers;Educate, inspire, empower and enlist the support of the community to prevent and prohibit animal cruelty;Strengthen the animal protection movement. (Animals Australia, “Who Is”)In delivery of this mission, the organisation curates public rallies and protests, makes government and industry submissions, and utilises corporate outreach. Campaigning engages the Web, multiple forms of print and broadcast media, and social media.With regards to Animals Australia’s campaigns regarding factory farming—including the Make It Possible campaign (see fig. 1), launched in 2013 and key to the period we are investigating—the main message is that: the animals kept in these barren and constrictive conditions are “no different to our pets at home”; they are “highly intelligent creatures who feel pain, and who will respond to kindness and affection – if given the chance”; they are “someone, not something” (see the Make It Possible transcript). Campaigns deliberately strive to engender feelings of empathy and produce affect in viewers (see, e.g., van Gurp). Specifically they strive to produce mainstream recognition of the cruelties entrenched in factory farming practices and build community outrage against these practices so as to initiate industry change. Campaigns thus expressly challenge Australians to no longer support factory farmed animal products, and to identify with what we have elsewhere called everyday activist positions (Rodan and Mummery, “Animal Welfare”; “Make It Possible”). They do not, however, explicitly endorse a vegan position. Figure 1: Make It Possible (Animals Australia, campaign poster)Nonetheless, as has been noted, a common counter-tactic used within Australia by the industries targeted by such campaigns, has been to use well-known negative stereotypes to discredit not only the charges of systemic animal cruelty but the associated organisations. In our analysis, we found four prominent interconnected stereotypes utilised in both digital and print media to discredit the animal welfare objectives of Animals Australia. Together these cast the organisation as: 1) anti-meat-eating; 2) anti-farming; 3) promoting a vegan agenda; and 4) hostile extremists. These stereotypes are examined below.Anti-Meat-EatingThe most common stereotype attributed to Animals Australia from its campaigning is of being anti-meat-eating. This charge, with its associations with veganism, is clearly problematic for industries that facilitate meat-eating and within a culture that normalises meat-eating, as the following example expresses:They’re [Animals Australia] all about stopping things. They want to stop factory farming – whatever factory farming is – or they want to stop live exports. And in fact they’re not necessarily about: how do I improve animal welfare in the pig industry? Or how do I improve animal welfare in the live export industry? Because ultimately they are about a meat-free future world and we’re about a meat producing industry, so there’s not a lot of overlap, really between what we’re doing. (Andrew Spencer, Australian Pork Ltd., qtd. in Clark)Respondents engaging this stereotype also express their “outrage at Coles” (McCarthy) and Animals Australia for “pedalling [sic]” a pro-vegan agenda (Nash), their sense that Animals Australia is operating with ulterior motives (Flint) and criminal intent (Brown). They see cultural refocus as unnecessary and “an exercise in futility” (Harris).Anti-FarmingTo be anti-farming in Australia is generally considered to be un-Australian, with Glasgow suggesting that any criticism of “farming practices” in Australian society can be “interpreted as an attack on the moral integrity of farmers, amounting to cultural blasphemy” (200). Given its objectives, it is unsurprising that Animals Australia has been stereotyped as being “anti-farming”, a phrase additionally often used in conjunction with the charge of veganism. Although this comprises a misreading of veganism—given its focus on challenging animal exploitation in farming rather than entailing opposition to all farming—the NFF accused Animals Australia of being “blatantly anti-farming and proveganism” (Linegar qtd. in Nason) and as wanting “to see animal agriculture phased out” (National Farmers’ Federation). As expressed in more detail:One of the main factors for VFF and other farmers being offended is because of AA’s opinion and stand on ALL farming. AA wants all farming banned and us all become vegans. Is it any wonder a lot of people were upset? Add to that the proceeds going to AA which may have been used for their next criminal activity washed against the grain. If people want to stand against factory farming they have the opportunity not to purchase them. Surely not buying a product will have a far greater impact on factory farmed produce. Maybe the money could have been given to farmers? (Hunter)Such stereotyping reveals how strongly normalised animal agriculture is in Australia, as well as a tendency on the part of respondents to reframe the challenge of animal cruelty in some farming practices into a position supposedly challenging all farming practices.Promoting a Vegan AgendaAs is already clear, Animals Australia is often reproached for promoting a vegan agenda, which, it is further suggested, it keeps hidden from the Australian public. This viewpoint was evident in two key examples: a) the Australian public and organisations such as the NFF are presented as being “defenceless” against the “myopic vitriol of the vegan abolitionists” (Jonas); and b) Animals Australia is accused of accepting “loans from liberation groups” and being “supported by an army of animal rights lawyers” to promote a “hard core” veganism message (Bourke).Nobody likes to see any animals hurt, but pushing a vegan agenda and pushing bad attitudes by group members is not helping any animals and just serves to slow any progress both sides are trying to resolve. (V.c. Deb Ford)Along with undermining farmers’ “legitimate business” (Jooste), veganism was also considered to undermine Australia’s rural communities (Park qtd. in Malone).Hostile ExtremistsThe final stereotype linking veganism with Animals Australia was of hostile extremism (cf. Cole and Morgan). This means, for users, being inimical to Australian national values but, also, being akin to terrorists who engage in criminal activities antagonistic to Australia’s democratic society and economic livelihood (see, e.g., Greer; ABC News). It is the broad symbolic threat that “extremism” invokes that makes this stereotype particularly “infectious” (Rosello 19).The latest tag team attacks on our pork industry saw AL giving crash courses in how to become a career criminal for the severely impressionable, after attacks on the RSPCA against the teachings of Peter Singer and trying to bully the RSPCA into vegan functions menu. (Cattle Advocate)The “extremists” want that extended to dairy products, as well. The fact that this will cause the total annihilation of practically all animals, wild and domestic, doesn’t bother them in the least. (Brown)What is interesting about these last two dimensions of stereotyping is their displacement of violence. That is, rather than responding to the charge of animal cruelty, violence and extremism is attributed to those making the charge.Stereotypes and Symbolic Boundary ShiftingWhat is evident throughout these instances is how stereotyping as a “cognitive mechanism” is being used to build boundaries (Cherry 460): in the first instance, between “us” (the meat-eating majority) and “them” (the vegan minority aka animal activists); and secondly between human interest and livestock. This point is that animals may hold instrumental value and receive some protection through such, but any more stringent arguments for their protection at the expense of perceived human interests tend to be seen as wrong-headed (Sorenson; Munro).These boundaries are deeply entrenched in Western culture (Wimmer). They are also deeply problematic in the context of animal activism because they fragment publics, promote restrictive identities, and close down public debate (Lamont and Molnár). Boundary entrenching is clearly evident in the stereotyping work carried out by industry stakeholders where meat-eating and practices of industrialised animal agriculture are valorised and normalised. Challenging Australia’s meat production practices—irrespective of the reason given—is framed and belittled as entailing a vegan agenda, and further as contributing to the demise of farming and rural communities in Australia.More broadly, industry stakeholders are explicitly targeting the activist work by such organisations as Animals Australia as undermining the ‘Australian way of life’. In their reading, there is an irreconcilable boundary between human and animal interests and between an activist minority which is vegan, unreasonable, extremist and hostile to farming and the meat-eating majority which is representative of the Australian community and sustains the Australian economy. As discussed so far, such stereotyping and boundary making—even in their inaccuracies—can be pernicious in the way they entrench identities and divisions, and close the possibility for public debate.Rather than directly contesting the presuppositions and inaccuracies of such stereotyping, however, Animals Australia can be read as cultivating a process of symbolic boundary shifting. That is, rather than responding by simply underlining its own moderate position of challenging only intensive animal agriculture for systemic animal cruelty, Animals Australia uses its campaigns to develop “boundary blurring and crossing” tactics (Cherry 451, 459), specifically to dismantle and shift the symbolic boundaries conventionally in place between humans and non-human animals in the first instance, and between those non-human animals used for companionship and those used for food in the second (see fig. 2). Figure 2: That Ain’t No Way to Treat a Lady (Animals Australia, campaign image on back of taxi)Indeed, the symbolic boundaries between humans and animals left unquestioned in the preceding stereotyping are being profoundly shaken by Animals Australia with campaigns such as Make It Possible making morally relevant likenesses between humans and animals highly visible to mainstream Australians. Namely, the organisation works to interpellate viewers to exercise their own capacities for emotional identification and moral imagination, to identify with animals’ experiences and lives, and to act upon that identification to demand change.So, rather than reactively striving to refute the aforementioned stereotypes, organisations such as Animals Australia are modelling and facilitating symbolic boundary shifting by building broad, emotionally motivated, pathways through which Australians are being encouraged to refocus their own assumptions, practices and identities regarding animal experience, welfare and animal-human relations. Indeed the organisation has explicitly framed itself as speaking on behalf of not only animals but all caring Australians, suggesting thereby the possibility of a reframing of Australian national identity. Although such a tactic does not directly contest this negative stereotyping—direct contestation being, as noted, ineffective given the perniciousness of stereotyping—such work nonetheless dismantles the oppositional charge of such stereotyping in calling for all Australians to proudly be a little bit anti-meat-eating (when that meat is from factory farmed animals), a little bit anti-factory farming, a little bit pro-veg*n, and a little bit proud to consider themselves as caring about animal welfare.For Animals Australia, in other words, appealing to Australians to care about animal welfare and to act in support of that care, not only defuses the stereotypes targeting them but encourages the work of symbolic boundary shifting that is really at the heart of this dispute. Further research into the reception of the debate would give a sense of the extent to which such an approach is making a difference.ReferencesABC News. “Animal Rights Activists ‘Akin to Terrorists’, Says NSW Minister Katrina Hodgkinson.” ABC News 18 Jul. 2013. 21 Feb. 2019 <http://www.abc.net.au/news/2013-07-18/animal-rights-activists-27terrorists272c-says-nsw-minister/4828556>.Animals Australia. “Who Is Animals Australia?” 20 Feb. 2019 <http://www.animalsaustralia.org/about>.———.

La production de fluor à l’état gazeux s’effectue par électrolyse de KF-2HF à 95°C. Dans le but d’améliorer ce procédé, de nouveaux composés carbonés tels que des nouveaux carbones et des électrodes sous forme de films minces réalisés en phase vapeur ont été testés comme matériau anodique et / ou comme séparateur de gaz. Des traitements chimiques ou mécaniques ont été réalisés pour orienter les propriétés de ces différents matériaux pour mieux répondre aux exigences lors de l’électrolyse. Une étude détaillée des différents modes de fluoration des matériaux au contact de KF-2HF et sous polarisation a été réalisée. Le comportement électrochimique a été corrélé avec les modifications structurales en surface (XPS et MEB) mais également au cœur de l’échantillon (DRX, RMN et porosimétrie mercure). Enfin, dans le but d’étudier le contact tri-phasique KF-2HF / matériau carboné / gaz (F2 ou H2), une méthode d’analyse de mouillabilité a été mise en place. Elle a permis d’identifier les paramètres importants telles que la nature des liaisons de surface, la rugosité ou encore la porosité pour orienter le caractère mouillant ou non mouillant de la surface des différents matériaux en fonction de l’application visée.

Cette étude porte sur les films DLC (diamond-like carbon). La charge critique lors d'un test de rayure augmente avec l'épaisseur inter-couche. Pour une épaisseur inter-couche donnée, la charge critique varie linéairement avec la dureté du film et son épaisseur. Le bas coefficient de frottement viendrait de la combinaison de la dureté élevée, de la faible rugosité et de la faible proportion de sp3. Dans le cas du fretting, le coefficient de frottement et l'humidité relative varient inversement. La proportion de sp3 augmente avec l'introduction de Si, ce qui fait monter la dureté, diminuer les frotements et augmenter la stabilité thermique de films a-SIC:H. L'augmentation de la fraction de sp3 dans les films a-C déposés par arc pulsé sous vide correspond bien à celles de la dureté et de la charge critique de rayure. Le fim a-C déposé par laser pulsé possède d'importantes contraintes internes. Un mécanisme de formation faisant appel à la théorie du flambement des coques est proposé. Le test de rayure des films DLC est divisé en 3 étapes : recouvrement élastique total, déformation plastique du film, délamination et écaillage du film. Cette résistance a d'abord été mesurée pour des films DLC sur substrat de Si. Il s'avère, à l'analyse élasto-plastique de la déformation au cours de la nanorayure, que la charge critique d'un film DLC sur Ti-6AI-4V est atteinte lorsque les déformations élastique et plastique sont comparables. L'analyse des expériences et de la morphologie de rayure nous permetttent de déduire que les mécanismes de rupture des films DLC sur Si et Ti-6AI-4V sont différents. Le relief des contraintes induits après rayure par le flambement a été modélisé afin de déterminer la charge de flambement critique. La rupture des films DLC sur Si, lors d'un test de rayure, a été modélisée en utilisant une analyse de flambement circulaire et ceci a été utilisé pour calculer énergie de rupture interfaciale et la résistance à la rupture.

Ce travail consiste en l'optimisation des conditions de dépôt par ablation laser à température ambiante du carbone et de l'alumine. Il se divise en huit parties principales. Le premier chapitre est une présentation du contexte de l'émergence des couches de carbone et d'alumine par ablation laser. le deuxième chapitre décrit les dispositifs expérimentaux et modes opératoires mis en œuvre, qu'ils concernent l'élaboration des films aussi bien que la détermination de leurs propriétés. Les deux chapitres suivants s'intéressent à résoudre les principaux défauts de l'ablation laser à savoir : La projection de particules solides lors du dépôt (chapitre 3) L'inhomogénéité en épaisseur des couches réalisées sur sustrat fixe (chapitre 4) le cinquième chapitre est consacré à l'étude des propriétés structurelles, électriques et mécaniques des couches de ta-C en fonction des conditiond de dépôt. Ce travail s'appuie sur une étude de l'énergie des ions dans le panache plasma (spectroscopie, imagerie résolue temporellement et spectralement) et leur rôle dans la croissance des films de ta-C (analyses Raman, XPS, MET...). le sixième chapitre reprend une étude similaire à ce qui a été présenté dans le chapitre précédent en l'applicant aux couches minces d'alumine par ablation laser. Enfin le dernier chapitre est consacré à l'intégration, dans les composants MEMS RF, des films d'alumine et de ta-C déposés par ablation laser. Ce chapitre rapporte les résultats de la collaboration menée avec l'IRCOM pour réaliser des composants fonctionnels (microcommutateurs RF, filtres accordables ...) à base de couches minces déposées par ablation laser.

Les revêtements Diamond-Like Carbon (DLC) sont des matériaux à base de carbone amorphe connus pour leur faible coefficient de frottement et leur bonne résistance à l’usure. L’utilisation de ceux-ci dans les moteurs automobiles permet de limiter les pertes en frottement, améliore les performances et confèrent une durée de vie rallongée au véhicules. L’incorporation des hétéroatomes dans la matrice du DLC permet de modifier leurs propriétés. Le choix des dopants permet d’adapter les propriétés des revêtements en fonction de l’application visée. L’étude présentée ici a mis en évidence l’influence de trois dopants métalliques (Al, Ti ou Nb) sur les propriétés physico-chimiques, mécaniques et tribologiques des revêtements Me-DLC (Me = Al, Ti ou Nb). Ces derniers ont été synthétisés par un procédé hybride combinant la pulvérisation cathodique magnétron et la PECVD. La structure ainsi que l’état de surface des revêtements varient en fonction du métal dopant et de sa concentration. Les caractérisations mécaniques montrent que le dopage des DLC par les trois métaux Al, Ti ou Nb entraine une réduction des contraintes résiduelles de compression, de la dureté et du module de Young. Une amélioration des coefficients de frottement est obtenue avec le dopage par l’aluminium et avec de petites quantités de titane et de niobium
Diamond-Like Carbon (DLC) coatings are amorphous carbon based materials known for their low coefficient of friction and good wear resistance. The use of DLC on mechanical parts in automotive engines can reduce friction losses, improve performance and give an extended life to vehicles. The incorporation of a heteroatom into the DLC matrix allows to modify their properties. The choice of the addition element makes it possible to adapt the properties of the coatings according to the intended application. The present study highlighted the influence of three metal doping elements (Al, Ti or Nb) on the physico-chemical, mechanical and tribological properties of Me-DLC coatings (Me = Al, Ti or Nb). These were synthesized by a hybrid process combining magnetron sputtering and PECVD. The structure as well as the morphology of the coatings change depending on the doping metal and its concentration. The mechanical characterizations show that the doping of the DLC by Al, Ti or Nb leads to a reduction of the residual compression stress, the hardness and the Young's modulus. An improvement of the friction coefficients is obtained with doping with aluminum and with small amounts of titanium or niobium
