Full textAbstract:
Purpose The purpose of this paper is to examine the role of access to skilled labor in explaining firms’ sales growth subject to the controlling influence of a wide range of firm-specific characteristics and country-level economic and non-economic factors. Design/methodology/approach The analysis uses a consistent and large firm-level data set from the World Bank’s Enterprise Surveys that includes 138 developing countries. An instrumental variables model with a GMM estimator is used for estimating the impact of access to skilled labor on firm performance. In order to obtain more robust estimators, the analysis introduces country-level controls reflecting the influence of economic and institutional factors, such as economic and financial development, institutional governance, education and technological progress. Findings The results document a significant and positive association between access to skilled labor and firm performance in the developing world. The explanatory power of access to skilled labor remains broadly robust after controlling for a wide range of firm-specific characteristics: sectoral and geographical influences matter. The results also show that the association between labor skill constraints and firm performance is mitigated by country-level factors but in diverse ways. Development, institutions, education and technological progress exert various mitigating effects on firm-level behavior regarding access to skilled labor. Originality/value The paper’s novel contribution is threefold: first, it uses joint firm, sector and country-level information to analyze the role of access to skilled labor on firm performance; second, it uses consistently produced information at the firm level from 138 developing countries; and, third, it considers the controlling impact of a wide range of country-level factors that reflect a country’s overall development, institutions and evolution.

Purpose – The purpose of this paper is to examine the innovative capabilities of biotech start-ups in relation to geographic proximity and knowledge sharing interaction in the R & D network of a major high-tech cluster. Design/methodology/approach – This study compares longitudinal informal communication networks of researchers at biotech start-ups with company patent applications in subsequent years. For a year, senior R & D staff members from over 70 biotech firms located in the Boston biotech cluster were polled and communication information about interaction with peers, universities and big pharmaceutical companies was collected, as well as their geolocation tags. Findings – Location influences the amount of communication between firms, but not their innovation success. Rather, what matters is communication intensity and recollection by others. In particular, there is evidence that rotating leadership – changing between a more active and passive communication style – is a predictor of innovative performance. Practical implications – Expensive real-estate investments can be replaced by maintaining social ties. A more dynamic communication style and more diverse social ties are beneficial to innovation. Originality/value – Compared to earlier work that has shown a connection between location, network and firm performance, this paper offers a more differentiated view; including a novel measure of communication style, using a unique data set and providing new insights for firms who want to shape their communication patterns to improve innovation, independently of their location.

Full textAbstract:
As the National Energy Market (NEM) changes to a more diverse grid with emissions reduction targets, the way we value technologies must also change (Boston et al. 2017). This change in value is fundamental as the future low emissions grid will require careful planning and implementation to guarantee the lowest total system cost is maintained, particularly as a net zero grid will be drastically larger than the current system. This planning must include system strength. The Australian Energy Market Operator Integrated System Plan states that the current market mechanisms cannot facilitate achieving a low emissions grid (Australian Energy Market Operator (AEMO) 2020a). Policy and market mechanisms will need to be designed for this changing system. If net zero is to be met, Modelling of Energy and Grid Services by Red Vector and Gamma Energy technology has shown that this future grid needs to contain: approximately 100GW of variable renewable energy; almost 20GW of firm, low emissions generation, such as gas or coal with carbon capture and storage (CCS), bioenergy with CCS and hydroelectric power. If CCS is not available, nuclear power will be required; more than 10GW of storage, including pumped hydro energy storage and other energy storage technologies and over 30GW of firm, dispatchable peaking plant, including coal- and gas-fired power generation. This study sets out the role for gas in a policy road map to net zero for the NEM, harnessing and reforming existing policies, as well as introducing new mechanisms to achieve net zero emissions while retaining a reliable grid at the lowest total system cost.

Full textAbstract:
Our nested case study shows how a China-based focal subsidiary of a Japanese MNC used various power bases to orchestrate a co-opetitive and diverse supplier ecosystem, and to drive cumulative cycles of collaborative capability development involving successive phases of capability gap articulation, evolution and institutionalization. All phases of capability development required the crossing of cognitive boundaries, which was facilitated by mutual engagement with boundary objects, and by common possession of generic background knowledge disseminated by the focal firm. The capability evolution phase also required the crossing of social and governance boundaries, which was supported and legitimized by shared framing assumptions about mutual benefit and continuous development, while the capability institutionalization phase also required the crossing of governance boundaries. Although the focal firm was open to suggestions for mutual benefit, it exercised unilateral control over design decisions, thereby pressurizing its suppliers to engage in capability development to meet specifications that they found arduous. Supplier diversity was a resource, and co-opetition a driving force for the discovery of solutions to manufacturability problems during the capability evolution phase, such that failure to develop requisite capabilities was uncommon.

Full textAbstract:
Our study examines a nontraditional engagement process employed by the City of Seattle during neighborhood plan updates. Adapting the trusted advocates model from the public health field, the city hired planning outreach liaisons (POLs) from 13 diverse community groups to solicit input from traditionally underrepresented residents. To explore the efficacy of this approach, we collected data through interviews with residents, neighborhood leaders, community development firm employees, university researchers, and municipal staff; a review of planning documents; observation at planning meetings. We found that the POLs effectively engaged underrepresented groups—including more than 1,200 stakeholders—particularly those characterized as self-organized, centralized or having strong social networks and were important in the advancement of democratic principles. Greater transparency by the city about process goals and constraints, along with strategies to address power issues, may have facilitated better communication and relationship building among the city, newly enfranchised residents, and the “usual suspects.”

Full textAbstract:
Purpose – The purpose of this paper is to provide empirical evidence on the influence of co-opetition on food exporting in different distribution channels, taking as reference the vegetable farming-marketing sector in southeast Spain. Design/methodology/approach – The study analyses the data collected from vegetable exporters’ associations and the firms’ individual financial reports. A multivariate empirical model is developed to measure the impact of cooperation and competition relationships (both horizontal and vertical ones) on exporting. This model includes the influence of main buyers distinguishing basically between retailers and wholesalers. Findings – The results obtained show that diverse forms of collaboration with competitors, in both horizontal (such as logistics and research projects) and vertical dimensions (such as promotion and quality certifications) have positive effects on vegetable export propensity. These influences become more apparent when large retailers are the main buyers. Research limitations/implications – The analysed farming-marketing sector features certain singular characteristics, for example the type of products and firms, which should be taken into account when extrapolating the results to other agrifood industries. Practical implications – For farming-marketing firms with little bargaining power in the supply chain of fresh produce, horizontal and vertical collaboration is a key factor in improving their exporting activity. A greater balance in co-opetition relationships is required to reduce the traditionally negative effect of competition among Spanish firms in the vegetable marketing sector. Originality/value – These findings should be of value to researchers into co-opetition policies and to managers responsible for strategy formation in international agrifood firm environment.

Journal of Accounting in Emerging Economies 10, no. 3 (June 6, 2020): 425–46. http://dx.doi.org/10.1108/jaee-03-2018-0027.
Full textAbstract:
PurposeThe purpose of the paper is to investigate the extent to which a model based on financial and non-financial variables predicts auditors' decisions to issue qualified audit reports in the case of companies listed on the Tehran Stock Exchange (TSE).Design/methodology/approachThe authors utilized data from the financial statements of 96 Iranian firms as the sample over a period of five years (2012–2016). A total of 480 observations were analysed using a probit model through 11 primary financial ratios accompanying non-financial variables, including the type of audit firm, auditor turnover and corporate performance, which affect the issuance of audit reports.FindingsThe results demonstrated high explanatory power of financial ratios and type of audit firm (the national audit organization vs other local audit firms) in explaining qualifications through audit reports. The predictive accuracy of the estimated model is evaluated using a regression model for the probabilities of qualified and clean opinions. The model is reliable, with 72.9% accuracy in classifying the total sample correctly to explain changes in the auditor's opinion.Research limitations/implicationsThis study contains some limitations. First, it is likely that similar researches in developed countries set a large sample (e.g. over 1,000 firms) including more years, but the authors cannot follow such a trend due to data access restrictions. Second, banks and financial institutions, investment and holding firms are removed from the sample, because their financial structure is diverse. The third limitation of the study represents the different economic and cultural conditions of Iran compared to other countries. Future studies could focus on internal control material weaknesses or earnings management to predict audit opinion in emerging economies including Iran.Practical implicationsThe paper has practical implications and can assist auditors in identifying factors motivating audit report qualifications, mainly in emerging economies.Originality/valueThe paper contributes to auditing research, since very little is known about the determinants of audit opinion in emerging markets including Iran; it also constitutes an addition to previous knowledge about audit opinion in the context of TSE. The paper is one of the rare studies predicting auditor opinions using both financial variables and non-financial metrics.

Full textAbstract:
Laughter is one of the most difficult and intriguing historical subjects, one that defies firm conclusion or systematization. Beginning with Dion Cassius’s first-person account of laughter in the Colosseum in 192 CE, this article explores some of the heuristic challenges of writing about the laughter of the past—particularly that of classical antiquity. It attempts to undermine some of the false certainties that surround the idea of a “ classical theory of laughter” (which originated during the Renaissance) and argues that ideas about laughter in ancient Greece and Rome were much more diverse than one usually imagines. Important patterns in the discursive use of laughter in ancient Rome can nonetheless be observed. This article also examines the way laughter was used to mediate political power and autocracy in addition to how laughter operated on the boundary between animals and humans. It concludes with a reflection on the extent to which we can still share in the laughter of the Romans and under what conditions.

Full textAbstract:
Abstract:In this paper we explore challenges facing leadership in a culture of “all consuming images” from a perspective which claims that images have a moral or normative dimension. The cumulative effect of contemporary image saturation is increased resistance to the normative power of an image. We also suggest that in a culturally diverse global economy, it is necessary to expand the moral aspects of good business leadership beyond providing a basis for productive, coherent group identity within a firm at the expense of seeing outsiders as “others.” We also explore what imagining leadership in business might be like in a world in which visual images shape our understandings of individual and group identity. While our focus is on leadership in business, we also use examples from the political arena. We also suggest that imagining business leadership in the ways we propose may be helpful to women, providing them with an image of business leadership more closely reflective of their experience of corporate culture, its limits, and possibilities.

Full textAbstract:
This chapter presents three very different partnership cases. The first focuses on partnerships among Rabobank, the second largest Dutch bank known for investments in food and agriculture worldwide, and two NGOs who worked with it to develop a climate-neutral credit card and to improve its investment portfolio’s carbon footprint. The second case addresses the collaborative design of a relicensing process for hydroelectric plants regulated by the U.S. Federal Energy Regulatory Commission (FERC). To improve the efficiency and equity of the relicensing process, FERC engaged in a collaborative governance process with stakeholders that produced new, widely legitimate relicensing procedures. The third reviews the IMF’s extended effort to build a partnership to address conflict over water contamination by a Peruvian gold mine. With many diverse local stakeholders and a resistant mining firm, this partnership struggled to achieve its goals. The case emphasizes the role of conveners, raising questions about partnering across power differences.

Full textAbstract:
Some countries develop the (general) skills of industrial workers largely through regular secondary education systems whereas other nations rely on a network of industrial schools and apprenticeship programs to offer their workers credentialed industry or firm-specific occupational skills. Skills Builders delves into the origins of diverse forms. First, patterns of industrial development and economic cleavages shaped the development of skills-training institutions; thus countries with stark regional heterogeneity have been less likely to develop national training systems. Second, the legacies from pre-industrial patterns of cooperation in some nations – most prominently, from the guild system – have encouraged both employers and workers to negotiate collective vocational training institutions. Third, the political features of the state (most importantly, the structure of party competition and degree of federal power sharing) reinforce or work against collectivist solutions to skills needs, cooperative industrial relations systems, and entrenched regional cleavages. Finally, both employers and workers become more committed to skills training when these groups are institutionally well-organized and are given a significant role in the creation and oversight of training programs.

Full textAbstract:
Genre, Authorship and Contemporary Women Filmmakers examines the significance of women’s contribution to genre cinema by highlighting the work of US filmmakers within and outside Hollywood – Kathryn Bigelow, Sofia Coppola, Nancy Meyers, Karyn Kusama and Kelly Reichardt, among others. Exploring genres as diverse as horror, the war movie, the Western, the costume biopic and the romantic comedy, Katarzyna Paszkiewicz interrogates questions of ‘genre’ authorship; the blurring of the borders between commercial and independent cinema and gendered discourses of (de)authorisation that operate within each sphere; ‘male’–‘female’ genre divisions; and the issue of authorial subversion in film and popular culture in a wider sense. With its focus on close analysis of the films themselves and the cultural and ideological meanings involved in the reception of genre texts authored by women, this book expands critical debates around women’s cinema and offers new perspectives on how contemporary filmmakers explore the aesthetic and imaginative power of genre.

Full textAbstract:
The Oxford Handbook of Feminist Theory provides an overview of the analytical frameworks and theoretical concepts feminist theorists have developed to challenge established knowledge. Leading feminist theorists, from around the globe, provide in-depth explorations of a diverse array of subject areas, capturing a plurality of approaches. The Handbook raises new questions, brings new evidence, and poses significant challenges across the spectrum of academic disciplines, demonstrating the interdisciplinary nature of feminist theory. The chapters offer innovative analyses of the central topics in social and political science (e.g. civilization, development, divisions of labor, economies, institutions, markets, migration, militarization, prisons, policy, politics, representation, the state/nation, the transnational, violence); cultural studies and the humanities (e.g. affect, agency, experience, identity, intersectionality, jurisprudence, narrative, performativity, popular culture, posthumanism, religion, representation, standpoint, temporality, visual culture); and discourses in medicine and science (e.g. cyborgs, health, intersexuality, nature, pregnancy, reproduction, science studies, sex/gender, sexuality, transsexuality) and contemporary critical theory that have been transformed through feminist theorization (e.g. biopolitics, coloniality, diaspora, the microphysics of power, norms/normalization, postcoloniality, race/racialization, subjectivity/subjectivation). The Handbook identifies the limitations of key epistemic assumptions that inform traditional scholarship and shows how theorizing from women’s and men’s lives has profound effects on the conceptualization of central categories, whether the field of analysis is aesthetics, biology, cultural studies, development, economics, film studies, health, history, literature, politics, religion, science studies, sexualities, violence, or war.

Full textAbstract:
This volume brings together multiple emerging strands of interest in language and linguistics. First is increasing attention on pedagogical scholarship in linguistics, signaled by the 2013 addition to the flagship journal Language of a series on Teaching Linguistics (see for example Sanders 2016) and by many recent panels and workshops on pedagogy at linguistics conferences around the world. Additionally, public outreach has gained greater prominence in the field, with linguists becoming more active and engaged with the public on social media and in podcasts. There has also been an increase in broader public interest in constructed languages (conlangs) and how to build them, indicated by the popularity of conlangs in film and television (e.g. Star Trek, Avatar, and Game of Thrones) and by the success of relevant books (e.g. Okrent 2010; Rosenfelder 2010; Peterson 2014, 2015). This volume showcases a variety of methods which instructors can use to tap into this public interest in conlangs and conlanging to reach a broader student population, increase their engagement with course material, deepen their understanding of linguistics and its interdisciplinary relationships, and provide opportunities for public outreach. Using language invention as a pedagogical tool is an innovative way to capitalize on the effectiveness of many modern educational approaches, such as problem-based learning, collaborative learning, and active learning, especially for a diverse cohort of learners. The methods and materials presented in this volume help cultivate students’ understanding of language, linguistic diversity, linguistic analysis, and the power of creativity.

Full textAbstract:
Transnational films representing intimacy and inequality disrupt and disgust Western spectators. When wounded bodies within poverty entangle with healthy wealthy bodies in sex, romance and care, fear and hatred combine with desire and fetishism. Works from the Philippines, South Korea, and independents from the United States and France may not be made for the West and may not make use of Hollywood traditions. Rather, they demand recognition for the knowledge they produce beyond our existing frames. They challenge us to go beyond passive consumption, or introspection of ourselves as spectators, for they represent new ways of world-making we cannot unsee, unhear, or unfeel. The spectator is redirected to go beyond the rapture of consuming the other to the rupture that arises from witnessing pain and suffering. Self-displacement is what proximity to intimate inequality in cinema ultimately compels and demands so as to establish an ethical way of relating to others. In undoing the spectator, the voice of the transnational filmmaker emerges. Not only do we need to listen to filmmakers from outside Hollywood who unflinchingly engage the inexpressibility of difference, we need to make room for critics and theorists who prioritize the subjectivities of others. When the demographics of filmmakers and film scholars are not as diverse as its spectators, films narrow our worldviews. To recognize our culpability in the denigration of others unleashes the power of cinema. The unbearability of stories we don’t want to watch and don’t want to feel must be borne.

November, Nancy. Beethoven's String Quartet in C-sharp Minor, Op. 131. Oxford University Press, 2021. http://dx.doi.org/10.1093/oso/9780190059200.001.0001.
Full textAbstract:
Beethoven’s String Quartet in C-sharp Minor, Op. 131 (1826) is firmly a part of the modern-day canon, and also makes its presence felt in popular culture, notably in film. Yet in recent times, the terms in which the work is discussed and presented tend to undermine the work’s power. Although it is held up as a masterpiece, Op. 131 has often been understood in monochrome terms, as a work portraying tragedy, struggle, loss, and lack. This book takes the modern-day listener well beyond these categories of adversity or deficit. It goes back to early reception documents, including Beethoven’s own writings about the work, to help the listener reinterpret the work and re-hear it. Analyses are geared toward allowing the reader to access earlier modes of listening and interpretation, those of listeners who celebrated the work precisely for its plenitude, its richness of invention or fantasy (in Beethoven’s own words). As connoisseur listeners of Beethoven’s day implied, Op. 131 is filled with diverse musical ideas (just like a fantasia), and with a new kind of string quartet writing that is calculated to promote sustained, engaged listening. Placing this work in the context of an emerging ideology of silent or “serious” listening in Beethoven’s Europe, the book considers how this particular “late” quartet could speak with special eloquence to a highly select but passionately enthusiastic audience. It also examines how and why the reception of Op. 131 has changed so profoundly from Beethoven’s time to our own.

A partir da segunda metade do século XX vemos na historiografia uma transformação estrutural. A entrada das mulheres nas universidades denunciou não só a exclusão das mulheres na História, mas a própria imparcialidade da narrativa histórica escrita até então. Neste primeiro momento vemos nascer a História das mulheres, que procurava localizar no passado aquelas que haviam sido apagadas da memória. Já num segundo momento, viu-se que apenas incluir as mulheres na narrativa oficial não era suficiente para solucionar um problema que de fato era profundo. O termo gênero surge então na busca de compreender as relações de poder criadas a partir da diferenciação sexual; a partir desse momento estuda-se não só a opressão vivida pelas mulheres, mas também outras formas de estruturação do poder, além da ampliação para estudos sobre sexualidade e masculinidade. Por fim, já na década de 80, surge a Teoria Queer que coloca em questão as pesquisas baseadas em identidades, e questiona a própria viabilidade de lidar com as categorias de gênero e sexo. Todas essas três abordagens estão incluídas num só movimento que busca trazer à tona as hierarquias, as relações de poder, a subjetividade e a construção de todas as categorias de gênero; com a finalidade de no presente transformar as relações de opressão e pensar mais a fundo a produção de sujeitos em nossa sociedade. Deste modo, esta chamada de capítulo tem como objetivo reunir os mais diversos trabalhos que tratam do tema, para que possamos ter uma visão mais ampla e complexa das relações de gênero da historiografia atual, e deste modo, contribuir para a superação das opressões e desigualdades em nosso próprio tempo.

Full textAbstract:
Neste volume da coleção Estudos Cindínicos, o leitor encontrará discussões com base em estudos e investigações desenvolvidas por profissionais de Portugal e Brasil. São discussões apresentadas e referenciadas no III Simpósio Ibero-Afro-Americano de Riscos, realizado na Universidade Federal de Uberlândia, Minas Gerais, Brasil, no período de 17 a 20 de junho de 2019 em parceria com a Riscos – Associação Portuguesa de Riscos, Prevenção e Segurança, com base na Universidade de Coimbra, Portugal. Os textos possuem como tema de diálogo a resiliência em situações de riscos, um dos três eixos estruturais do referido evento científico. Neste sentido, este volume sobre Resiliência e Riscos tem por objetivo trazer à tona o conhecimento e o debate acerca de realidades territoriais em que as comunidades ameaçadas, poder público e empreendedores, submetidos às inúmeras situações de risco e mesmo de administração de um acidente e/ou desastre, conseguem e/ou conseguiram experiências de êxito com relação à gestão de tais fenômenos. Vivemos num tempo em que o mercado gera necessidades de consumo cada vez mais em grande escala. Em tal ritmo ocorre a submissão de pessoas e ambientes a uma diversidade cada vez maior dos tipos de riscos. Esta situação exige das comunidades ameaçadas, poder público e empresas implicadas, a previsão dos riscos para melhor gestá-los e garantir um mínimo de segurança, ou no caso de crises ter estabelecida a capacidade de resposta à altura dos problemas. Assim, a leitura deste livro pode inspirar investigadores, gestores públicos e pessoas em geral um vez que, em diferentes situações de riscos, sujeitos sociais foram e são capazes de, em meio a desafios enormes provenientes de riscos, atuarem sobre os territórios a fim de torná-los seguros ou até mesmo de superação em casos de tragédias. Clara demonstração que a mesma criação humana de situações das mais diversas modalidades de riscos, é de onde surge a capacidade e a força social de enfrentamento, determinação e gestão eficiente do território a fim de torná-lo seguro e saudável à vida humana e às outras formas vitais do ambiente.

This second genre chapter explores Power’s work within comedies, most of which were made in the mid-1930s. In his comedic roles, Power was able to establish himself as an extremely handsome cocky young American that helped him appeal to audiences at the time, particularly female film fans. His comedies allowed Power to express a diverse range of facial expressions, distinct vocal intonation and wide grins which soon became established features of his star image. Perhaps most importantly for his developing star image, the analysis of his comedies in this chapter reveal how Power was being established as a star with erotic appeal whom audiences are invited to gaze at and desire, an element of his star image that endured throughout his career.

Full textAbstract:
Though The Spanish Earth (1937) is likely the only film most readers will associate with the novelist Dos Passos, the other three film projects he undertook, both produced and unproduced, provide new insight into the cinematic aesthetics that inform the methods of his ground-breaking modernist novels. Although his later fiction incorporated fewer innovative adaptations of film devices into their styles, in novels such as Most Likely to Succeed (1954) he continued to address what he saw as the failure of the film industry to fulfil its artistic and cultural potential. But innovative filmmakers in the twenty-first century have frequently cited Dos Passos’s narrative devices and preoccupations as central influences, and current films exploring the power of monopolistic corporations and consumerism and blurring distinctions among genres echo the writer’s modernist themes and methods. The diverse range of Dos Passos’s own cinematic viewing throughout his life reflects his lifelong interest in new ways of telling a story.

Full textAbstract:
Festivals have tremendous power to engage diverse audiences with new forms of cultural consumption, but also provide opportunities for enlightening debate and encouraging action for social change. The Bristol Radical Film Festival (BRFF) takes place annually in venues throughout the city of Bristol, in the South West of England, presenting a curated programme of ‘radical’ films and documentaries which are screened in non-traditional venues. Drawing on ideas of Latin American radical film making, the organisers explicitly sought to use the festival to connect community activists within the city. This chapter examines how festival organisers used the cultural capital of their association with the University of the West of England to help legitimise their activities, under the radar of university managers to create a novel form of societal impact.

Full textAbstract:
This chapter explores the impact of a specific type of economic elite in the technocracy on contemporary urban planning. These are the financial and advanced business services (FABS) such as legal, tax, property, and other advisory firms — the ‘technicians’ who keep the financial capitalist system afloat. The chapter argues that this diverse landscape of private experts is becoming increasingly influential in shaping public planning policies and private corporate strategies in real estate development, yet they operate as unaccountable actors, far from any transparent democratic process. The role of the FABS industry is characterised by this sector's ability to generate power and strategic knowledge that determines urban and regional development. The chapter develops and exemplifies its argument in the context of Luxembourg and its vastly dynamic financial economy.

This chapter explores the status, meaning, use, and conflation of gendered orifices and bodily fluids in pornographic adaptations of Bram Stoker’s Dracula. In speaking the supposed silences of Dracula, porn adaptations of the novel must carefully navigate gender and sexuality. These adaptations reveal how hardcore film as a whole operates on anxious ground similar to that of Stoker’s novel, simultaneously invoking and resisting sexual anxieties concerning gendered penetration, gendered fluids, and consumption. Dracula, as a culture text, mobilizes queered, gendered, and raced reformulations of consumer and consumed, queering ostensibly straight pornographies, destabilizing supposedly rigid gender dynamics, and resituating the colonial Other. Dracula adaptations invoke and redeploy the racialized implications of nineteenth-century vampirism, channeling racial and sexual subjectivity through vampirism. Dracula penetrates a supposedly sanctified pornotopia, enabling diverse and perverse sexual representations that are instructive in understanding pornography as erotically engaged with sexual fluidity, genre instability, and oscillating power dynamics.

Full textAbstract:
This chapter on “Socioeconomic Development in India: Lessons from the Third Sector” is a broad overview of India’s economic growth and human development since independence in 1947. It traces the evolving role of government, market, and civil society in navigating the global political economy and the creative tension in which they have coexisted. The chapter dives deeply into the civil society sector which once inspired the founding of Ashoka and is now referred to as a hotbed of social enterprises. The sector which once had firm foundations in pluralist social movements and a focus on social innovation now struggles to distinguish social business from social entrepreneurship. The current ecosystem, while extensive, lacks focus, disregards questions of power, and lacks accountability mechanisms. The goals of improving lives and affecting social change would be better served by focusing on social innovation, treating people as stakeholders rather than clients, and protecting and promoting citizen participation in a democratic economy, society, and polity.

Full textAbstract:
Most major competition authorities are authorized to prohibit mergers and acquisitions affecting their territory and to condition approval of a proposed merger on changes to the merger agreement (e.g., requiring a participant to divest certain assets). Many laws also require the participating parties to notify the competition authority before the transaction is completed (premerger notification). Combining independent firms into one unit (known generally as a merger) can greatly increase the power of the resulting entity and affect markets in many parts of the world. For example, if the two largest and most successful manufacturers of computer chips in the world combine, the consequences will be felt almost everywhere. Some competition law regimes have greater capacity (e.g., economic and political leverage) to influence mergers than others, and the chapter identifies the factors that determine how much influence a particular merger law is likely to have. It examines the procedures common to these regimes and the standards that competition law institutions use in evaluating them. The chapter also looks at how these rules and procedures create a complex global web of firms, competition authorities, and economic experts.

This chapter interrogates the geopolitical implications of a contemporary development in the region’s media industries — the institutionalization of location shooting into modes of nation branding that commoditize cultural signs in line with the states’ soft power objectives. Drawing from examples of recent location-shot film and media, including En Chen’s Island Etude, Chi Po-lin’s Beyond Beauty, and Zhejiang TV's Keep Running, I demonstrate how location shooting since Taiwan’s membership in the WTO has been institutionalized within the discursive contours of the “Love Taiwan” movement, a process which can be compared with the PRC’s marketing of the “Chinese Dream” to domestic tourists via convergent and place-based film and televisual media. While the resulting national brands could not appear more different, these discourses operate on the shared assumption that for place identities to be readily consumable and exportable, they must be coherent within a global “experience economy” that circulates images of distinctive yet fixed cultural identities. This reduction of place into readily consumable cultural signs can be contrasted with the enigmatic representation of Shanghai found in Jia Zhangke's I Wish I Knew, which fashions on-screen Doreen Massey’s notion of the “progressive place,” a poststructuralist reinterpretation of place that focuses on conflicting sociocultural processes that imbue spaces with richly layered meanings. Building on Massey's concept of the progressive place, this chapter argues that location-shot film and media in China and Taiwan, more than offering diversely themed experiences, have untapped potential in cultivating alternative public cultures through reflexive, minor, and performative modes of place making.

Este capítulo aborda as contribuições da Terapia Ocupacional, enquanto uma profissão e área do conhecimento que se preocupa em promover e facilitar o envolvimento de pessoas, coletivos e populações em ocupações no espaço social, a fim de promover o direito à cidade. O Direito à Cidade é um conceito que compreende a real participação dos sujeitos na produção e reprodução do espaço urbano. Trata-se de um direito social e humano pautado desde os anos 1970 por diversos movimentos sociais no Brasil. No entanto, há assimetrias no poder de uso do território da cidade, marcado e controlado pelo mercado capitalista neoliberalista. Assim, o espaço social das cidades se materializa em desigualdades socioterritoriais, que se tornam barreiras para a maioria dos sujeitos participarem plenamente da cidade, como nas ocupações de lazer, festas, se alimentar, utilizar transportes, morar, trabalhar, conviver, entre outras. Neste contexto, as políticas urbanas surgem com força no período de redemocratização do Brasil, tentando diminuir os abismos sociais e orientar soluções, a partir da convergência do trabalho interdisciplinar de diversas áreas do conhecimento e da participação popular. Considerando que a cidade é o local privilegiado das ocupações humanas, o não direito de participar dela deveria ser tomado como pauta emergente para a profissão, uma vez que a Terapia Ocupacional contemporânea cumpre com esforços de criar meios e condições de garantia de direitos sociais e cidadania à diversas populações. Neste sentido, as questões que implicam na legitimação e experiência do Direito à Cidade têm relações diretas com a produção e envolvimento em ocupações. Pois, é no espaço social das cidades que as ocupações são produzidas e produzem as cidades. Desta forma, o direito à cidade tem impacto no acesso e mobilidade dos sujeitos na construção e realização da vida, assim como no acesso e cuidado qualificado nos serviços de saúde, educação, assistência social, cultura, entre outros.

The final chapter dives deeper into the territory of spin-off blockchains offered as technological modes of organisation for decentralising a host of socioeconomic practices. Recent discussions of platform capitalism are used to critique claims that blockchains are an incorruptible mode of democratic governance. Instead, blockchain capitalism is offered as a more accurate transaction model where profit necessitates certain points of centralisation through dominant distributed ledger technologies. A close examination of blockchain typologies reveals the co-option of these architectures by the very centralised banking firms and governments they were initially designed to bypass. As financial giants and central banks design their own distributed ledgers to increase the efficiency of business practices and monetary policy, innovation from the disruptive edges is once again absorbed into “the centre” by the corporate/state powers that be.

Electricity from diverse renewable energy (RE) resources may be converted to gaseous hydrogen (GH2) and anhydrous ammonia (NH3) carbon-free fuels and stored at < $1.00 / KWh capital cost in large, solution-mined salt caverns for GH2 and in large, refrigerated, “atmospheric” liquid surface tanks as NH3. This stored chemical energy is gathered and transmitted and distributed via continental-scale underground pipeline systems and converted to useful work, at residential to industrial scales, via combined-heat-and-power (CHP) plants, via direct space heating and cooling, and as transportation fuels. We thus solve RE’s severe transmission, storage, and integration problems via complete, optimized, systems design — from photons and moving air and water molecules to delivered energy services. We need to supply all energy, not just electricity, from diverse renewable energy (RE) resources, both distributed and centralized, where the world’s richest RE resources — of large geographic extent and high intensity — are stranded: far from end-users with inadequate or nonexistent gathering and transmission systems to deliver the energy. Electricity systems may be suboptimal, technically and economically, at such large scale. Electricity energy storage cannot affordably firm large, intermittent renewables at annual scale, while carbon-free GH2 and liquid NH3 fuels can: GH2 in large solution-mined salt caverns, NH3 in steel surface tanks, both pressurized and refrigerated.

Full textAbstract:
The world’s richest renewable energy resources — of large geographic extent and high intensity — are stranded: far from end-users with inadequate or nonexistent gathering and transmission systems to deliver the energy. The energy output of most renewables varies greatly, at time scales of seconds to seasons: the energy capture assets thus operate at inherently low capacity factor (CF); energy delivery to end-users is not “firm”. New electric transmission systems, or fractions thereof, dedicated to renewables, will suffer the same low CF, and represent substantial stranded capital assets, which increases the cost of delivered renewable-source energy. Electric energy storage cannot affordably firm large renewables at annual scale. At gigawatt (GW = 1,000 MW) scale, renewable-source electricity from diverse sources, worldwide, can be converted to hydrogen and oxygen, via high-pressure-output electrolyzers, with the hydrogen pipelined to load centers (cities, refineries, chemical plants) for use as vehicle fuel, combined-heat-and-power generation on the retail side of the customers’ meters, ammonia production, and petroleum refinery feedstock. The oxygen byproduct may be sold to adjacent dry biomass and / or coal gasification plants. Figures 1–3. New, large, solution-mined salt caverns in the southern Great Plains, and probably elsewhere in the world, may economically store enough energy as compressed gaseous hydrogen (GH2) to “firm” renewables at annual scale, adding great market and strategic value to diverse, stranded, rich, renewable resources. Figures 2 and 3. For example, Great Plains, USA, wind energy, if fully harvested and “firmed” and transmitted to markets, could supply the entire energy consumption of USA. If gathered, transmitted, and delivered as hydrogen, about 15,000 new solution-mined salt caverns, of ∼8 million cubic feet (225,000 cubic meters) each, would be required, at an incremental capital cost to the generation-transmission system of ∼5%. We report the results of several studies of the technical and economic feasibility of large-scale renewables — hydrogen systems. Windplants are the lowest-cost new renewable energy sources; we focus on wind, although concentrating solar power (CSP) is probably synergistic and will become attractive in cost. The largest and richest renewable resources in North America, with high average annual windspeed and sunlight, are stranded in the Great Plains: extant electric transmission capacity is insignificant relative to the resource potential. Large, new, electric transmission systems will be costly, difficult to site and permit, and may be difficult to finance, because of public opposition, uncertainties about transmission cost recovery, and inherently low CF in renewables service. The industrial gas companies’ decades of success and safety in operating thousands of km of GH2 pipelines worldwide is encouraging, but these are relatively short, small-diameter pipelines, and operating at low and constant pressure: not subject to the technical demands of renewables-hydrogen service (RHS), nor to the economic challenge of delivering low-volumetric-energy-density GH2 over hundreds or thousands of km to compete with other hydrogen sources at the destination. The salt cavern storage industry is also mature; several GH2 storage caverns have been in service for over twenty years; construction and operating and maintenance (O&M) costs are well understood; O&M costs are low.

COP15, Copenhagen, December 09, failed partly for lack of a credible, comprehensive vision for how we may, and must soon, “run the world on renewables”. We cannot, and should not try to, accomplish this entirely with electricity transmission. The world’s richest renewable energy (RE) resources — of large geographic extent and high intensity — are stranded: far from end-users with inadequate or nonexistent gathering and transmission systems to deliver the energy. Electricity energy storage cannot affordably firm large, intermittent renewables at annual scale, while gaseous hydrogen (GH2) and anhydrous ammonia (NH3) fuels can: GH2 in large solution-mined salt caverns, NH3 in surface tanks, interconnected via underground pipelines in RE systems for gathering, transmission, distribution, and end use. Thus, we need to think beyond electricity as we plan new “transmission” systems for bringing large, stranded RE resources to distant markets as annually-firm C-free energy, to empower subsequent efforts to COP15. Recent press has extolled the global RE vision, but without adequate attention to the diverse transmission and storage systems required for achievement. [21] At GW scale, renewable-source electricity from diverse sources can be converted to hydrogen and byproduct oxygen, and/or to NH3, pipelined underground to load centers for use as vehicle fuel and combined-heat-and-power generation on the wholesale or retail side of the customers’ meters. The ICE, CT, and fuel cell operate very efficiently on GH2 and NH3 fuels. USA has extensive extant NH3 pipeline and tank storage infrastructure.

Making the electricity grid “smarter” does not: 1. Increase physical transmission capacity; 2. Provide affordable annual-scale firming storage for RE; 3. Solve grid integration problem for large, time-varying RE; 4. Alleviate NIMBY objections to new transmission siting; 5. Reduce the high O&M costs of overhead electric lines. The “smarter” grid may be more vulnerable to cyberattack. Adding storage, control, and quality adjunct devices to the electricity grid, to accommodate very high renewables content, may be technically and economically inferior to GH2 and NH3 RE systems. Thus, we need to look beyond “smart grid”, expanding our concept of “transmission”, to synergistically and simultaneously solve the transmission, firming storage, and RE integration “balancing” problems now severely constraining our progress toward “running the world on renewables”.

Abstract Fire protection and appropriate management are important to ensure security of nuclear facilities alike other industries. While relevant hazard analyses have been successfully carried out for commercial reactors, based on recently strengthened IAEA guideline and national standards, examination of research reactors is also required. The objective of this study is to represent integrity assessment of safety related cables connected to operating console in the control room of a zero-power research reactor. Two postulated electrical fire scenarios were identified among diverse accident causes and systematically analyzed by two numerical softwares with different turbulence models. Both polyvinyl chloride and cross-linked polyethylene were selected, respectively, as the representatives of various thermoplastic and thermoset cable materials. As results, temperature and heat flux profiles of the cables were calculated. Their maximum values were compared with the corresponding damage criteria, of which details and key findings will be discussed.

Full textAbstract:
Adiabatic film-cooling effectiveness is examined on a high pressure turbine blade by varying three critical engine parameters, viz., coolant blowing ratio, coolant-to-mainstream density ratio and freestream turbulence intensity. Three average coolant blowing ratios (BR = 1.2, 1.7, and 2.2 on the pressure side and BR = 1.1, 1.4, and 1.8 on the suction side), three average coolant density ratios (DR = 1.0, 1.5, and 2.5), and two average freestream turbulence intensities (Tu = 4.2% and 10.5%) are considered. Conduction-free Pressure Sensitive Paint (PSP) technique is adopted to measure film-cooling effectiveness. Three foreign gases— N2 for low density, CO2 for medium density, and a mixture of SF6 and Argon for high density are selected to study the effect of coolant density. The test blade features 2 rows of cylindrical film-cooling holes on the suction side (45° compound), 4 rows on the pressure side (45° compound) and 3 around the leading edge (30° radial). The inlet and the exit Mach numbers are 0.24 and 0.44, respectively. Reynolds number of the mainstream flow is 7.5E105 based on the exit velocity and blade chord length. Results suggest that the PSP is a powerful technique capable of producing clear and detailed film effectiveness contours with diverse foreign gases. Large improvement on the pressure side and moderate improvement on the suction side effectiveness is witnessed when blowing ratio is raised from 1.2 to 1.7 and 1.1 to 1.4, respectively. No major improvement is seen thereafter with the downstream half of the suction side showing drop in effectiveness. The effect of increasing coolant density is to increase effectiveness everywhere on the pressure surface and suction surface except for the small region on the suction side, xss/Cx<0.2. Higher freestream turbulence causes effectiveness to drop everywhere except in the region downstream of the suction side where significant improvement in effectiveness is seen.

Cooling is required to enable the turbine components to survive and have acceptable life in the very high gas temperatures occurring in modern engines. The cooling air is bled from the compression system, with typically about 15% of the core flow being diverted in military engines and about 20% in civil turbofans. Cooling benefits engine specific thrust and efficiency by allowing higher cycle temperatures to be employed, but the bleed air imposes cycle penalties and also reduces the aerodynamic efficiency of the turbine blading, typically by 2–4%. Cooling research aims to develop and validate improved design methodologies that give maximum cooling effectiveness for minimum cooling flow. This paper documents external cooling research undertaken in the Isentropic Light Piston Facility at QinetiQ as part of a European collaborative programme on turbine aerodynamics and heat transfer. In Phase I, neither the ngv nor the rotor was cooled; cooling was added to the ngv only for Phase II, and to the rotor and ngv in Phase III. Coolant blowing rates and density ratios were also varied in the experiments. This paper describes the ILPF and summarises the results of this systematic programme, paying particular attention to the variation in aerofoil heat transfer with changing coolant conditions, and the effects coolant ejection has on the aerofoil’s aerodynamic performance.

Abstract The rapid regulation of gas turbine power plants is becoming increasingly important. In the field of stationary gas turbine power augmentation droplet-laden flows receive special attention as they cool the compressor’s inlet temperature. High fogging is an effective and economic method that secures power supply by reacting rapidly to fluctuating power generation. However, water droplets effect the aerodynamic performance of the compressor negatively. Therefore, the Laboratory of Turbomachinery investigated the interaction between droplets and blades at midspan by using diverse experimental methods to comprehend aerodynamic performance and water film induced losses. Additionally, the knowledge of the separation’s extent for three-dimensional flows with corner separation is of great importance as it leads to a blockage of the flow cross-section and therefore contributes to the losses. This paper enlarges this knowledge base by studying the interactions of the dispersed phase with the gas flow in three-dimensional flow structures as they are found in the near wall regions of every turbo compressor. By utilizing a three-dimensional Phase-Doppler Anemometer spatially resolved information on velocity mean vector, its higher moments as well as droplet diameters were extracted from the separated region for a compressor blade, in middle cross section design, with spray-injection. Streamlines that derive from the mean velocities visualize key features such as saddle and focal points. Then an integral approach is presented to evaluate the effect of the dispersed phase on the flow structure compared to dry flow and the impact back on different diameter classes. Finally, the velocity in streamwise direction shows the influence of the disperse phase on the aerodynamic blockage.

Full textAbstract:
A flow modification technique is introduced in an attempt to allow increased turbine inlet temperatures. A large-scale two half-blade cascade simulator is used to model the secondary flow between two adjacent turbine blades. Various flow visualization techniques and measurements are used to verify that the test section replicates the flow of an actual turbine engine. Two techniques are employed to modify the endwall secondary flow, specifically the path of the passage vortex. Six endwall jets are installed at a location downstream of the saddle point near the leading edge of the pressure side blade. These wall jets are found to be ineffective in diverting the path of the passage vortex. The second technique utilizes a row of 12 endwall jets whose positions along the centerline of the passage are based on results from an optimized boundary layer fence. The row of jets successfully diverts the path of the passage vortex and decreases its effect on the suction side blade. This can be expected to increase the effectiveness of film cooling in that area. The row of jets increases the aerodynamic losses in the passage, however. Secondary flow measurements are presented showing the development of the endwall flow, both with and without modification.
