Academic literature on the topic 'Tod alphabet'

Abstract Motivation A large variety of pairwise measures of similarity or dissimilarity have been developed for comparing phylogenetic trees, e.g. species trees or gene trees. Due to its intuitive definition in terms of tree clades and bipartitions and its computational efficiency, the Robinson-Foulds (RF) distance is the most widely used for trees with unweighted edges and labels restricted to leaves (representing the genetic elements being compared). However, in the case of gene trees, an important information revealing the nature of the homologous relation between gene pairs (orthologs, paralogs, xenologs) is the type of event associated to each internal node of the tree, typically speciations or duplications, but other types of events may also be considered, such as horizontal gene transfers. This labeling of internal nodes is usually inferred from a gene tree/species tree reconciliation method. Here, we address the problem of comparing such event-labeled trees. The problem differs from the classical problem of comparing uniformly labeled trees (all labels belonging to the same alphabet) that may be done using the Tree Edit Distance (TED) mainly due to the fact that, in our case, two different alphabets are considered for the leaves and internal nodes of the tree, and leaves are not affected by edit operations. Results We propose an extension of the RF distance to event-labeled trees, based on edit operations comparable to those considered for TED: node insertion, node deletion and label substitution. We show that this new Labeled Robinson Foulds (LRF) distance can be computed in linear time, in addition of maintaining other desirable properties: being a metric, reducing to RF for trees with no labels on internal nodes and maintaining an intuitive interpretation. The algorithm for computing the LRF distance enables novel analyses on event-label trees such as reconciled gene trees. Here, we use it to study the impact of taxon sampling on labeled gene tree inference, and conclude that denser taxon sampling yields trees with better topology but worse labeling.

While the term “visual literacy” has grown in popularity in the last 50 years, its meaning remains nebulous. It is described variously as: a vehicle for aesthetic appreciation, a means of defence against visual manipulation, a sorting mechanism for an increasingly data-saturated age, and a prerequisite to civic inclusion (Fransecky 23; Messaris 181; McTigue and Flowers 580). Scholars have written extensively about the first three subjects but there has been less research on how visual literacy frames civic life and how it might help the public as a tool to address disadvantage and assist in removing social and cultural barriers. This article examines a forerunner to visual literacy in the push to create an international symbol language born out of popular education movements, a project that fell short of its goals but still left a considerable impression on graphic media. This article, then, presents an analysis of visual literacy campaigns in the early postwar era. These campaigns did not attempt to invent a symbolic language but posited that images themselves served as a universal language in which students could receive training. Of particular interest is how the concept of visual literacy has been mobilised as a pedagogical tool in design, digital humanities and in broader civic education initiatives promoted by Third Space institutions. Behind the creation of new visual literacy curricula is the idea that images can help anchor a world community, supplementing textual communication. Figure 1: Visual Literacy Yearbook. Montebello Unified School District, USA, 1973. Shedding Light: Origins of the Visual Literacy Frame The term “visual literacy” came to the fore in the early 1970s on the heels of mass literacy campaigns. The educators, creatives and media theorists who first advocated for visual learning linked this aim to literacy, an unassailable goal, to promote a more radical curricular overhaul. They challenged a system that had hitherto only acknowledged a very limited pathway towards academic success; pushing “language and mathematics”, courses “referred to as solids (something substantial) as contrasted with liquids or gases (courses with little or no substance)” (Eisner 92). This was deemed “a parochial view of both human ability and the possibilities of education” that did not acknowledge multiple forms of intelligence (Gardner). This change not only integrated elements of mass culture that had been rejected in education, notably film and graphic arts, but also encouraged the critique of images as a form of good citizenship, assuming that visually literate arbiters could call out media misrepresentations and manipulative political advertising (Messaris, “Visual Test”). This movement was, in many ways, reactive to new forms of mass media that began to replace newspapers as key forms of civic participation. Unlike simple literacy (being able to decipher letters as a mnemonic system), visual literacy involves imputing meanings to images where meanings are less fixed, yet still with embedded cultural signifiers. Visual literacy promised to extend enlightenment metaphors of sight (as in the German Aufklärung) and illumination (as in the French Lumières) to help citizens understand an increasingly complex marketplace of images. The move towards visual literacy was not so much a shift towards images (and away from books and oration) but an affirmation of the need to critically investigate the visual sphere. It introduced doubt to previously upheld hierarchies of perception. Sight, to Kant the “noblest of the senses” (158), was no longer the sense “least affected” by the surrounding world but an input centre that was equally manipulable. In Kant’s view of societal development, the “cosmopolitan” held the key to pacifying bellicose states and ensuring global prosperity and tranquillity. The process of developing a cosmopolitan ideology rests, according to Kant, on the gradual elimination of war and “the education of young people in intellectual and moral culture” (188-89). Transforming disparate societies into “a universal cosmopolitan existence” that would “at last be realised as the matrix within which all the original capacities of the human race may develop” and would take well-funded educational institutions and, potentially, a new framework for imparting knowledge (Kant 51). To some, the world of the visual presented a baseline for shared experience. Figure 2: Exhibition by the Gesellschafts- und Wirtschaftsmuseum in Vienna, photograph c. 1927. An International Picture Language The quest to find a mutually intelligible language that could “bridge worlds” and solder together all of humankind goes back to the late nineteenth century and the Esperanto movement of Ludwig Zamenhof (Schor 59). The expression of this ideal in the world of the visual picked up steam in the interwar years with designers and editors like Fritz Kahn, Gerd Arntz, and Otto and Marie Neurath. Their work transposing complex ideas into graphic form has been rediscovered as an antecedent to modern infographics, but the symbols they deployed were not to merely explain, but also help education and build international fellowship unbounded by spoken language. The Neuraths in particular are celebrated for their international picture language or Isotypes. These pictograms (sometimes viewed as proto-emojis) can be used to represent data without text. Taken together they are an “intemporal, hieroglyphic language” that Neutrath hoped would unite working-class people the world over (Lee 159). The Neuraths’ work was done in the explicit service of visual education with a popular socialist agenda and incubated in the social sphere of Red Vienna at the Gesellschafts- und Wirtschaftsmuseum (Social and Economic Museum) where Otto served as Director. The Wirtschaftsmuseum was an experiment in popular education, with multiple branches and late opening hours to accommodate the “the working man [who] has time to see a museum only at night” (Neurath 72-73). The Isotype contained universalist aspirations for the “making of a world language, or a helping picture language—[that] will give support to international developments generally” and “educate by the eye” (Neurath 13). Figure 3: Gerd Arntz Isotype Images. (Source: University of Reading.) The Isotype was widely adopted in the postwar era in pre-packaged sets of symbols used in graphic design and wayfinding systems for buildings and transportation networks, but with the socialism of the Neuraths’ peeled away, leaving only the system of logos that we are familiar with from airport washrooms, charts, and public transport maps. Much of the uptake in this symbol language could be traced to increased mobility and tourism, particularly in countries that did not make use of a Roman alphabet. The 1964 Olympics in Tokyo helped pave the way when organisers, fearful of jumbling too many scripts together, opted instead for black and white icons to represent the program of sports that summer. The new focus on the visual was both technologically mediated—cheaper printing and broadcast technologies made the diffusion of image increasingly possible—but also ideologically supported by a growing emphasis on projects that transcended linguistic, ethnic, and national borders. The Olympic symbols gradually morphed into Letraset icons, and, later, symbols in the Unicode Standard, which are the basis for today’s emojis. Wordless signs helped facilitate interconnectedness, but only in the most literal sense; their application was limited primarily to sports mega-events, highway maps, and “brand building”, and they never fulfilled their role as an educational language “to give the different nations a common outlook” (Neurath 18). Universally understood icons, particularly in the form of emojis, point to a rise in visual communication but they have fallen short as a cosmopolitan project, supporting neither the globalisation of Kantian ethics nor the transnational socialism of the Neuraths. Figure 4: Symbols in use. Women's bathroom. 1964 Tokyo Olympics. (Source: The official report of the Organizing Committee.) Counter Education By mid-century, the optimism of a universal symbol language seemed dated, and focus shifted from distillation to discernment. New educational programs presented ways to study images, increasingly reproducible with new technologies, as a language in and of themselves. These methods had their roots in the fin-de-siècle educational reforms of John Dewey, Helen Parkhurst, and Maria Montessori. As early as the 1920s, progressive educators were using highly visual magazines, like National Geographic, as the basis for lesson planning, with the hopes that they would “expose students to edifying and culturally enriching reading” and “develop a more catholic taste or sensibility, representing an important cosmopolitan value” (Hawkins 45). The rise in imagery from previously inaccessible regions helped pupils to see themselves in relation to the larger world (although this connection always came with the presumed superiority of the reader). “Pictorial education in public schools” taught readers—through images—to accept a broader world but, too often, they saw photographs as a “straightforward transcription of the real world” (Hawkins 57). The images of cultures and events presented in Life and National Geographic for the purposes of education and enrichment were now the subject of greater analysis in the classroom, not just as “windows into new worlds” but as cultural products in and of themselves. The emerging visual curriculum aimed to do more than just teach with previously excluded modes (photography, film and comics); it would investigate how images presented and mediated the world. This gained wider appeal with new analytical writing on film, like Raymond Spottiswoode's Grammar of the Film (1950) which sought to formulate the grammatical rules of visual communication (Messaris 181), influenced by semiotics and structural linguistics; the emphasis on grammar can also be seen in far earlier writings on design systems such as Owen Jones’s 1856 The Grammar of Ornament, which also advocated for new, universalising methods in design education (Sloboda 228). The inventorying impulse is on display in books like Donis A. Dondis’s A Primer of Visual Literacy (1973), a text that meditates on visual perception but also functions as an introduction to line and form in the applied arts, picking up where the Bauhaus left off. Dondis enumerates the “syntactical guidelines” of the applied arts with illustrations that are in keeping with 1920s books by Kandinsky and Klee and analyse pictorial elements. However, at the end of the book she shifts focus with two chapters that examine “messaging” and visual literacy explicitly. Dondis predicts that “an intellectual, trained ability to make and understand visual messages is becoming a vital necessity to involvement with communication. It is quite likely that visual literacy will be one of the fundamental measures of education in the last third of our century” (33) and she presses for more programs that incorporate the exploration and analysis of images in tertiary education. Figure 5: Ideal spatial environment for the Blueprint charts, 1970. (Image: Inventory Press.) Visual literacy in education arrived in earnest with a wave of publications in the mid-1970s. They offered ways for students to understand media processes and for teachers to use visual culture as an entry point into complex social and scientific subject matter, tapping into the “visual consciousness of the ‘television generation’” (Fransecky 5). Visual culture was often seen as inherently democratising, a break from stuffiness, the “artificialities of civilisation”, and the “archaic structures” that set sensorial perception apart from scholarship (Dworkin 131-132). Many radical university projects and community education initiatives of the 1960s made use of new media in novel ways: from Maurice Stein and Larry Miller’s fold-out posters accompanying Blueprint for Counter Education (1970) to Emory Douglas’s graphics for The Black Panther newspaper. Blueprint’s text- and image-dense wall charts were made via assemblage and they were imagined less as charts and more as a “matrix of resources” that could be used—and added to—by youth to undertake their own counter education (Cronin 53). These experiments in visual learning helped to break down old hierarchies in education, but their aim was influenced more by countercultural notions of disruption than the universal ideals of cosmopolitanism. From Image as Text to City as Text For a brief period in the 1970s, thinkers like Marshall McLuhan (McLuhan et al., Massage) and artists like Bruno Munari (Tanchis and Munari) collaborated fruitfully with graphic designers to create books that mixed text and image in novel ways. Using new compositional methods, they broke apart traditional printing lock-ups to superimpose photographs, twist text, and bend narrative frames. The most famous work from this era is, undoubtedly, The Medium Is the Massage (1967), McLuhan’s team-up with graphic designer Quentin Fiore, but it was followed by dozens of other books intended to communicate theory and scientific ideas with popularising graphics. Following in the footsteps of McLuhan, many of these texts sought not just to explain an issue but to self-consciously reference their own method of information delivery. These works set the precedent for visual aids (and, to a lesser extent, audio) that launched a diverse, non-hierarchical discourse that was nonetheless bound to tactile artefacts. In 1977, McLuhan helped develop a media textbook for secondary school students called City as Classroom: Understanding Language and Media. It is notable for its direct address style and its focus on investigating spaces outside of the classroom (provocatively, a section on the third page begins with “Should all schools be closed?”). The book follows with a fine-grained analysis of advertising forms in which students are asked to first bring advertisements into class for analysis and later to go out into the city to explore “a man-made environment, a huge warehouse of information, a vast resource to be mined free of charge” (McLuhan et al., City 149). As a document City as Classroom is critical of existing teaching methods, in line with the radical “in the streets” pedagogy of its day. McLuhan’s theories proved particularly salient for the counter education movement, in part because they tapped into a healthy scepticism of advertisers and other image-makers. They also dovetailed with growing discontent with the ad-strew visual environment of cities in the 1970s. Budgets for advertising had mushroomed in the1960s and outdoor advertising “cluttered” cities with billboards and neon, generating “fierce intensities and new hybrid energies” that threatened to throw off the visual equilibrium (McLuhan 74). Visual literacy curricula brought in experiential learning focussed on the legibility of the cities, mapping, and the visualisation of urban issues with social justice implications. The Detroit Geographical Expedition and Institute (DGEI), a “collective endeavour of community research and education” that arose in the aftermath of the 1967 uprisings, is the most storied of the groups that suffused the collection of spatial data with community engagement and organising (Warren et al. 61). The following decades would see a tamed approach to visual literacy that, while still pressing for critical reading, did not upend traditional methods of educational delivery. Figure 6: Beginning a College Program-Assisting Teachers to Develop Visual Literacy Approaches in Public School Classrooms. 1977. ERIC. Searching for Civic Education The visual literacy initiatives formed in the early 1970s both affirmed existing civil society institutions while also asserting the need to better inform the public. Most of the campaigns were sponsored by universities, major libraries, and international groups such as UNESCO, which published its “Declaration on Media Education” in 1982. They noted that “participation” was “essential to the working of a pluralistic and representative democracy” and the “public—users, citizens, individuals, groups ... were too systematically overlooked”. Here, the public is conceived as both “targets of the information and communication process” and users who “should have the last word”. To that end their “continuing education” should be ensured (Study 18). Programs consisted primarily of cognitive “see-scan-analyse” techniques (Little et al.) for younger students but some also sought to bring visual analysis to adult learners via continuing education (often through museums eager to engage more diverse audiences) and more radical popular education programs sponsored by community groups. By the mid-80s, scores of modules had been built around the comprehension of visual media and had become standard educational fare across North America, Australasia, and to a lesser extent, Europe. There was an increasing awareness of the role of data and image presentation in decision-making, as evidenced by the surprising commercial success of Edward Tufte’s 1982 book, The Visual Display of Quantitative Information. Visual literacy—or at least image analysis—was now enmeshed in teaching practice and needed little active advocacy. Scholarly interest in the subject went into a brief period of hibernation in the 1980s and early 1990s, only to be reborn with the arrival of new media distribution technologies (CD-ROMs and then the internet) in classrooms and the widespread availability of digital imaging technology starting in the late 1990s; companies like Adobe distributed free and reduced-fee licences to schools and launched extensive teacher training programs. Visual literacy was reanimated but primarily within a circumscribed academic field of education and data visualisation. Figure 7: Visual Literacy; What Research Says to the Teacher, 1975. National Education Association. USA. Part of the shifting frame of visual literacy has to do with institutional imperatives, particularly in places where austerity measures forced strange alliances between disciplines. What had been a project in alternative education morphed into an uncontested part of the curriculum and a dependable budget line. This shift was already forecasted in 1972 by Harun Farocki who, writing in Filmkritik, noted that funding for new film schools would be difficult to obtain but money might be found for “training in media education … a discipline that could persuade ministers of education, that would at the same time turn the budget restrictions into an advantage, and that would match the functions of art schools” (98). Nearly 50 years later educators are still using media education (rebranded as visual or media literacy) to make the case for fine arts and humanities education. While earlier iterations of visual literacy education were often too reliant on the idea of cracking the “code” of images, they did promote ways of learning that were a deep departure from the rote methods of previous generations. Next-gen curricula frame visual literacy as largely supplemental—a resource, but not a program. By the end of the 20th century, visual literacy had changed from a scholarly interest to a standard resource in the “teacher’s toolkit”, entering into school programs and influencing museum education, corporate training, and the development of public-oriented media (Literacy). An appreciation of image culture was seen as key to creating empathetic global citizens, but its scope was increasingly limited. With rising austerity in the education sector (a shift that preceded the 2008 recession by decades in some countries), art educators, museum enrichment staff, and design researchers need to make a case for why their disciplines were relevant in pedagogical models that are increasingly aimed at “skills-based” and “job ready” teaching. Arts educators worked hard to insert their fields into learning goals for secondary students as visual literacy, with the hope that “literacy” would carry the weight of an educational imperative and not a supplementary field of study. Conclusion For nearly a century, educational initiatives have sought to inculcate a cosmopolitan perspective with a variety of teaching materials and pedagogical reference points. Symbolic languages, like the Isotype, looked to unite disparate people with shared visual forms; while educational initiatives aimed to train the eyes of students to make them more discerning citizens. The term ‘visual literacy’ emerged in the 1960s and has since been deployed in programs with a wide variety of goals. Countercultural initiatives saw it as a prerequisite for popular education from the ground up, but, in the years since, it has been formalised and brought into more staid curricula, often as a sort of shorthand for learning from media and pictures. The grand cosmopolitan vision of a complete ‘visual language’ has been scaled back considerably, but still exists in trace amounts. Processes of globalisation require images to universalise experiences, commodities, and more for people without shared languages. Emoji alphabets and globalese (brands and consumer messaging that are “visual-linguistic” amalgams “increasingly detached from any specific ethnolinguistic group or locality”) are a testament to a mediatised banal cosmopolitanism (Jaworski 231). In this sense, becoming “fluent” in global design vernacular means familiarity with firms and products, an understanding that is aesthetic, not critical. It is very much the beneficiaries of globalisation—both state and commercial actors—who have been able to harness increasingly image-based technologies for their benefit. To take a humorous but nonetheless consequential example, Spanish culinary boosters were able to successfully lobby for a paella emoji (Miller) rather than having a food symbol from a less wealthy country such as a Senegalese jollof or a Morrocan tagine. This trend has gone even further as new forms of visual communication are increasingly streamlined and managed by for-profit media platforms. The ubiquity of these forms of communication and their global reach has made visual literacy more important than ever but it has also fundamentally shifted the endeavour from a graphic sorting practice to a critical piece of social infrastructure that has tremendous political ramifications. Visual literacy campaigns hold out the promise of educating students in an image-based system with the potential to transcend linguistic and cultural boundaries. This cosmopolitan political project has not yet been realised, as the visual literacy frame has drifted into specialised silos of art, design, and digital humanities education. It can help bridge the “incomplete connections” of an increasingly globalised world (Calhoun 112), but it does not have a program in and of itself. Rather, an evolving visual literacy curriculum might be seen as a litmus test for how we imagine the role of images in the world.

IntroductionIf human beings have become a geophysical force, capable of impacting the very crust and atmosphere of the planet, and if geophysical forces become objects of study, presences able to be charted over millions of years—one of our many problems is a 'naming' problem. - Bethany NowviskieThe anthropocene "denotes the present time interval, in which many geologically significant conditions and processes are profoundly altered by human activities" (S.Q.S.). Although the narrative and terminology of the anthropocene has not been officially legitimized by the scientific community as a whole, it has been adopted worldwide by a plethora of social and cultural studies. The challenges of the anthropocene demand interdisciplinary efforts and actions. New contexts, situations and environments call for original naming propositions: new terminologies are always illegitimate at the moment of their first appearance in the world.Against the background of the naming challenges of the anthropocene, we will map the emergence and tell the story of a tiny world within the world of media studies: the world of the term 'nanomedia' and its hyphenated sister 'nano-media'. While we tell the story of the uses of this term, its various meanings and applications, we will provide yet another possible interpretation and application to the term, one that we believe might be helpful to interdisciplinary media studies in the context of the anthropocene. Contemporary media terminologies are usually born out of fortuitous exchanges between communication technologies and their various social appropriations: hypodermic media, interactive media, social media, and so on and so forth. These terminologies are either recognised as the offspring of legitimate scientific endeavours by the media theory community, or are widely discredited and therefore rendered illegitimate. Scientific legitimacy comes from the broad recognition and embrace of a certain term and its inclusion in the canon of an epistemology. Illegitimate processes of theoretical enquiry and the study of the kinds of deviations that might deem a theory unacceptable have been scarcely addressed (Delborne). Rejected terminologies and theories are marginalised and gain the status of bastard epistemologies of media, considered irrelevant and unworthy of mention and recognition. Within these margins, however, different streams of media theories which involve conceptual hybridizations can be found: creole encounters between high culture and low culture (James), McLuhan's hybrid that comes from the 'meeting of two media' (McLuhan 55), or even 'bastard spaces' of cultural production (Bourdieu). Once in a while a new media epistemology arises that is categorised as a bastard not because of plain rejection or criticism, but because of its alien origins, formations and shape. New theories are currently emerging out of interdisciplinary and transdisciplinary thinking which are, in many ways, bearers of strange features and characteristics that might render its meaning elusive and obscure to a monodisciplinary perspective. Radical transdisciplinary thinking is often alien and alienated. It results from unconventional excursions into uncharted territories of enquiry: bastard epistemologies arise from such exchanges. Being itself a product of a mestizo process of thinking, this article takes a look into the term nanomedia (or nano-media): a marginal terminology within media theory. This term is not to be confounded with the term biomedia, coined by Eugene Thacker (2004). (The theory of biomedia has acquired a great level of scientific legitimacy, however it refers to the moist realities of the human body, and is more concerned with cyborg and post-human epistemologies. The term nanomedia, on the contrary, is currently being used according to multiple interpretations which are mostly marginal, and we argue, in this paper, that such uses might be considered illegitimate). ’Nanomedia’ was coined outside the communications area. It was first used by scientific researchers in the field of optics and physics (Rand et al), in relation to flows of media via nanoparticles and optical properties of nanomaterials. This term would only be used in media studies a couple of years later, with a completely different meaning, without any acknowledgment of its scientific origins and context. The structure of this narrative is thus illegitimate, and as such does not fit into traditional modalities of written expression: there are bits and pieces of information and epistemologies glued together as a collage of nano fragments which combine philology, scientific literature, digital ethnography and technology reviews. Transgressions Illegitimate theories might be understood in terms of hybrid epistemologies that intertwine disciplines and perspectives, rendering its outcomes inter or transdisciplinary, and therefore prone to being considered marginal by disciplinary communities. Such theories might also be considered illegitimate due to social and political power struggles which aim to maintain territory by reproducing specific epistemologies within a certain field. Scientific legitimacy is a social and political process, which has been widely addressed. Pierre Bourdieu, in particular, has dedicated most of his work to deciphering the intricacies of academic wars around the legitimacy or illegitimacy of theories and terminologies. Legitimacy also plays a role in determining the degree to which a certain theory will be regarded as relevant or irrelevant:Researchers’ tendency to concentrate on those problems regarded as the most important ones (e.g. because they have been constituted as such by producers endowed with a high degree of legitimacy) is explained by the fact that a contribution or discovery relating to those questions will tend to yield greater symbolic profit (Bourdieu 22).Exploring areas of enquiry which are outside the boundaries of mainstream scientific discourses is a dangerous affair. Mixing different epistemologies in the search for transversal grounds of knowledge might result in unrecognisable theories, which are born out of a combination of various processes of hybridisation: social, technological, cultural and material.Material mutations are happening that call for new epistemologies, due to the implications of current technological possibilities which might redefine our understanding of mediation, and expand it to include molecular forms of communication. A new terminology that takes into account the scientific and epistemological implications of nanotechnology applied to communication [and that also go beyond cyborg metaphors of a marriage between biology and cibernetics] is necessary. Nanomedia and nanomediations are the terminologies proposed in this article as conceptual tools to allow these further explorations. Nanomedia is here understood as the combination of different nanotechnological mediums of communication that are able to create and disseminate meaning via molecular exchange and/ or assembly. Nanomediation is here defined as the process of active transmission and reception of signs and meaning using nanotechnologies. These terminologies might help us in conducting interdisciplinary research and observations that go deeper into matter itself and take into account its molecular spaces of mediation - moving from metaphor into pragmatics. Nanomedia(s)Within the humanities, the term 'nano-media' was first proposed by Mojca Pajnik and John Downing, referring to small media interventions that communicate social meaning in independent ways. Their use of term 'nano-media' proposes to be a revised alternative to the plethora of terms that categorise such media actions, such as alternative media, community media, tactical media, participatory media, etc. The metaphor of smallness implied in the term nano-media is used to categorise the many fragments and complexities of political appropriations of independent media. Historical examples of the kind of 'nano' social interferences listed by Downing (2),include the flyers (Flugblätter) of the Protestant Reformation in Germany; the jokes, songs and ribaldry of François Rabelais’ marketplace ... the internet links of the global social justice (otromundialista) movement; the worldwide community radio movement; the political documentary movement in country after country.John Downing applies the meaning of the prefix nano (coming from the Greek word nanos - dwarf), to independent media interventions. His concept is rooted in an analysis of the social actions performed by local movements scattered around the world, politically engaged and tactically positioned. A similar, but still unique, proposition to the use of the term 'nano-media' appeared 2 years later in the work of Graham St John (442):If ‘mass media’ consists of regional and national print and television news, ‘niche media’ includes scene specific publications, and ‘micro media’ includes event flyers and album cover art (that which Eshun [1998] called ‘conceptechnics’), and ‘social media’ refers to virtual social networks, then the sampling of popular culture (e.g. cinema and documentary sources) using the medium of the programmed music itself might be considered nano-media.Nano-media, according to Graham St John, "involves the remediation of samples from popular sources (principally film) as part of the repertoire of electronic musicians in their efforts to create a distinct liminalized socio-aesthetic" (St John 445). While Downing proposes to use the term nano-media as a way to "shake people free of their obsession with the power of macro-media, once they consider the enormous impact of nano-technologies on our contemporary world" (Downing 1), Graham St John uses the term to categorise media practices specific to a subculture (psytrance). Since the use of the term 'nano-media' in relation to culture seems to be characterised by the study of marginalised social movements, portraying a hybrid remix of conceptual references that, if not completely illegitimate, would be located in the border of legitimacy within media theories, I am hereby proposing yet another bastard version of the concept of nanomedia (without a hyphen). Given that neither of the previous uses of the term 'nano-media' within the discipline of media studies take into account the technological use of the prefix nano, it is time to redefine the term in direct relation to nanotechnologies and communication devices. Let us start by taking a look at nanoradios. Nanoradios are carbon nanotubes connected in such a way that when electrodes flow through the nanotubes, various electrical signals recover the audio signals encoded by the radio wave being received (Service). Nanoradios are examples of the many ways in which nanotechnologies are converging with and transforming our present information and communication technologies. From molecular manufacturing (Drexler) to quantum computing (Deutsch), we now have a wide spectrum of emerging and converging technologies that can act as nanomedia - molecular structures built specifically to act as communication devices.NanomediationsBeyond literal attempts to replicate traditional media artifacts using nanotechnologies, we find deep processes of mediation which are being called nanocommunication (Hara et al.) - mediation that takes place through the exchange of signals between molecules: Nanocommunication networks (nanonetworks) can be used to coordinate tasks and realize them in a distributed manner, covering a greater area and reaching unprecedented locations. Molecular communication is a novel and promising way to achieve communication between nanodevices by encoding messages inside molecules. (Abadal & Akyildiz) Nature is nanotechnological. Living systems are precise mechanisms of physical engineering: our molecules obey our DNA and fall into place according to biological codes that are mysteriously written in our every cell. Bodies are perfectly mediated - biological systems of molecular communication and exchange. Humans have always tried to emulate or to replace natural processes by artificial ones. Nanotechnology is not an exception. Many nanotechnological applications try to replicate natural systems, for example: replicas of nanostructures found in lotus flowers are now being used in waterproof fabrics, nanocrystals, responsible for resistance of cobwebs, are being artificially replicated for use in resistant materials, and various proteins are being artificially replicated as well (NNI 05). In recent decades, the methods of manipulation and engineering of nano particles have been perfected by scientists, and hundreds of nanotechnological products are now being marketed. Such nano material levels are now accessible because our digital technologies were advanced enough to allow scientific visualization and manipulation at the atomic level. The Scanning Tunneling Microscopes (STMs), by Gerd Binnig and Heinrich Rohrer (1986), might be considered as the first kind of nanomedia devices ever built. STMs use quantum-mechanical principles to capture information about the surface of atoms and molecules, allowed digital imaging and visualization of atomic surfaces. Digital visualization of atomic surfaces led to the discovery of buckyballs and nanotubes (buckytubes), structures that are celebrated today and received their names in honor of Buckminster Fuller. Nanotechnologies were developed as a direct consequence of the advancement of digital technologies in the fields of scientific visualisation and imaging. Nonetheless, a direct causal relationship between nano and digital technologies is not the only correlation between these two fields. Much in the same manner in which digital technologies allow infinite manipulation and replication of data, nanotechnologies would allow infinite manipulation and replication of molecules. Nanocommunication could be as revolutionary as digital communication in regards to its possible outcomes concerning new media. Full implementation of the new possibilities of nanomedia would be equivalent or even more revolutionary than digital networks are today. Nanotechnology operates at an intermediate scale at which the laws of classical physics are mixed to the laws of quantum physics (Holister). The relationship between digital technologies and nanotechnologies is not just instrumental, it is also conceptual. We might compare the possibilities of nanotechnology to hypertext: in the same way that a word processor allows the expression of any type of textual structure, so nanotechnology could allow, in principle, for a sort of "3-D printing" of any material structure.Nanotechnologies are essentially media technologies. Nanomedia is now a reality because digital technologies made possible the visualization and computational simulation of the behavior of atomic particles at the nano level. Nanomachines that can build any type of molecular structure by atomic manufacturing could also build perfect replicas of themselves. Obviously, such a powerful technology offers medical and ecological dangers inherent to atomic manipulation. Although this type of concern has been present in the global debate about the social implications of nanotechnology, its full implications are yet not entirely understood. A general scientific consensus seems to exist, however, around the idea that molecules could become a new type of material alphabet, which, theoretically, would make possible the reconfiguration of the physical structures of any type of matter using molecular manufacturing. Matter becomes digital through molecular communication.Although the uses given to the term nano-media in the context of cultural and social studies are merely metaphorical - the prefix nano is used by humanists as an allegorical reference of a combination between 'small' and 'contemporary' - once the technological and scientifical realities of nanomedia present themselves as a new realm of mediation, populated with its own kind of molecular devices, it will not be possible to ignore its full range of implications anymore. A complexifying media ecosystem calls for a more nuanced and interdisciplinary approach to media studies.ConclusionThis article narrates the different uses of the term nanomedia as an illustration of the way in which disciplinarity determines the level of legitimacy or illegitimacy of an emerging term. We then presented another possible use of the term in the field of media studies, one that is more closely aligned with its scientific origins. The importance and relevance of this narrative is connected to the present challenges we face in the anthropocene. The reality of the anthropocene makes painfully evident the full extent of the impact our technologies have had in the present condition of our planet's ecosystems. For as long as we refuse to engage directly with the technologies themselves, trying to speak the language of science and technology in order to fully understand its wider consequences and implications, our theories will be reduced to fancy metaphors and aesthetic explorations which circulate around the critical issues of our times without penetrating them. The level of interdisciplinarity required by the challenges of the anthropocene has to go beyond anthropocentrism. Traditional theories of media are anthropocentric: we seem to be willing to engage only with that which we are able to recognise and relate to. Going beyond anthropocentrism requires that we become familiar with interdisciplinary discussions and perspectives around common terminologies so we might reach a consensus about the use of a shared term. For scientists, nanomedia is an information and communication technology which is simultaneously a tool for material engineering. For media artists and theorists, nano-media is a cultural practice of active social interference and artistic exploration. However, none of the two approaches is able to fully grasp the magnitude of such an inter and transdisciplinary encounter: when communication becomes molecular engineering, what are the legitimate boundaries of media theory? If matter becomes not only a medium, but also a language, what would be the conceptual tools needed to rethink our very understanding of mediation? Would this new media epistemology be considered legitimate or illegitimate? Be it legitimate or illegitimate, a new media theory must arise that challenges and overcomes the walls which separate science and culture, physics and semiotics, on the grounds that it is a transdisciplinary change on the inner workings of media itself which now becomes our vector of epistemological and empirical transformation. A new media theory which not only speaks the language of molecular technologies but that might be translated into material programming, is the only media theory equipped to handle the challenges of the anthropocene.
