Academic literature on the topic 'Wireless communication systems – Technological innovations – South Africa'

The wireless communication industry using radio spectrum is recently going through major innovations and advancements. With this transformation, the demand for and usage of radio spectrum has increased exponentially making radio spectrum indeed a scarce natural resource. In order to solve this problem, the possibility of opening up the unused portions of licensed spectrum by sharing using cognitive radio technology has been in the spotlight for maximizing radio spectrum utilization as well to as ensure sufficient radio spectrum availability for future wireless services and applications. With this objective in mind, this paper looks at the principles and technologies of cooperative spectrum sensing in cognitive radio environment in improving radio spectrum utilization. The paper provides a comprehensive review on spectrum sensing as a key functional requirement for cognitive radio technology by focusing on its application on dynamic spectrum access that enables unused portions of licensed spectrum to be used in an opportunistic manner as long as the operation of the unlicensed user will not affect that of the licensed user. In satisfying this dynamic spectrum access requirement, a friendly interactive graphical user interface (GUI) spectrum sensing application program was developed. The detail activities involve in the development of the application program, also known as spectrum sensing and detection algorithm (SSADA), was fully documented and presented in the paper. The developed graphical user interface application program after successfully developed was evaluated. The performance evaluations of developed graphical user interface sensing algorithm show that the algorithm performs favourably well. The program overall evaluation results provide bedrock information on how to improve cooperative spectrum sensing gain without incurring a cooperative overhead.

When George Orwell encountered ideas of a technological utopia sixty-five years ago, he acted the grumpy middle-aged man Reading recently a batch of rather shallowly optimistic “progressive” books, I was struck by the automatic way in which people go on repeating certain phrases which were fashionable before 1914. Two great favourites are “the abolition of distance” and “the disappearance of frontiers”. I do not know how often I have met with the statements that “the aeroplane and the radio have abolished distance” and “all parts of the world are now interdependent” (1944). It is worth revisiting the old boy’s grumpiness, because the rhetoric he so niftily skewers continues in our own time. Facebook features “Peace on Facebook” and even claims that it can “decrease world conflict” through inter-cultural communication. Twitter has announced itself as “a triumph of humanity” (“A Cyber-House” 61). Queue George. In between Orwell and latter-day hoody cybertarians, a whole host of excitable public intellectuals announced the impending end of materiality through emergent media forms. Marshall McLuhan, Neil Postman, Daniel Bell, Ithiel de Sola Pool, George Gilder, Alvin Toffler—the list of 1960s futurists goes on and on. And this wasn’t just a matter of punditry: the OECD decreed the coming of the “information society” in 1975 and the European Union (EU) followed suit in 1979, while IBM merrily declared an “information age” in 1977. Bell theorized this technological utopia as post-ideological, because class would cease to matter (Mattelart). Polluting industries seemingly no longer represented the dynamic core of industrial capitalism; instead, market dynamism radiated from a networked, intellectual core of creative and informational activities. The new information and knowledge-based economies would rescue First World hegemony from an “insurgent world” that lurked within as well as beyond itself (Schiller). Orwell’s others and the Cold-War futurists propagated one of the most destructive myths shaping both public debate and scholarly studies of the media, culture, and communication. They convinced generations of analysts, activists, and arrivistes that the promises and problems of the media could be understood via metaphors of the environment, and that the media were weightless and virtual. The famous medium they wished us to see as the message —a substance as vital to our wellbeing as air, water, and soil—turned out to be no such thing. Today’s cybertarians inherit their anti-Marxist, anti-materialist positions, as a casual glance at any new media journal, culture-industry magazine, or bourgeois press outlet discloses. The media are undoubtedly important instruments of social cohesion and fragmentation, political power and dissent, democracy and demagoguery, and other fraught extensions of human consciousness. But talk of media systems as equivalent to physical ecosystems—fashionable among marketers and media scholars alike—is predicated on the notion that they are environmentally benign technologies. This has never been true, from the beginnings of print to today’s cloud-covered computing. Our new book Greening the Media focuses on the environmental impact of the media—the myriad ways that media technology consumes, despoils, and wastes natural resources. We introduce ideas, stories, and facts that have been marginal or absent from popular, academic, and professional histories of media technology. Throughout, ecological issues have been at the core of our work and we immodestly think the same should apply to media communications, and cultural studies more generally. We recognize that those fields have contributed valuable research and teaching that address environmental questions. For instance, there is an abundant literature on representations of the environment in cinema, how to communicate environmental messages successfully, and press coverage of climate change. That’s not enough. You may already know that media technologies contain toxic substances. You may have signed an on-line petition protesting the hazardous and oppressive conditions under which workers assemble cell phones and computers. But you may be startled, as we were, by the scale and pervasiveness of these environmental risks. They are present in and around every site where electronic and electric devices are manufactured, used, and thrown away, poisoning humans, animals, vegetation, soil, air and water. We are using the term “media” as a portmanteau word to cover a multitude of cultural and communications machines and processes—print, film, radio, television, information and communications technologies (ICT), and consumer electronics (CE). This is not only for analytical convenience, but because there is increasing overlap between the sectors. CE connect to ICT and vice versa; televisions resemble computers; books are read on telephones; newspapers are written through clouds; and so on. Cultural forms and gadgets that were once separate are now linked. The currently fashionable notion of convergence doesn’t quite capture the vastness of this integration, which includes any object with a circuit board, scores of accessories that plug into it, and a global nexus of labor and environmental inputs and effects that produce and flow from it. In 2007, a combination of ICT/CE and media production accounted for between 2 and 3 percent of all greenhouse gases emitted around the world (“Gartner Estimates,”; International Telecommunication Union; Malmodin et al.). Between twenty and fifty million tonnes of electronic waste (e-waste) are generated annually, much of it via discarded cell phones and computers, which affluent populations throw out regularly in order to buy replacements. (Presumably this fits the narcissism of small differences that distinguishes them from their own past.) E-waste is historically produced in the Global North—Australasia, Western Europe, Japan, and the US—and dumped in the Global South—Latin America, Africa, Eastern Europe, Southern and Southeast Asia, and China. It takes the form of a thousand different, often deadly, materials for each electrical and electronic gadget. This trend is changing as India and China generate their own media detritus (Robinson; Herat). Enclosed hard drives, backlit screens, cathode ray tubes, wiring, capacitors, and heavy metals pose few risks while these materials remain encased. But once discarded and dismantled, ICT/CE have the potential to expose workers and ecosystems to a morass of toxic components. Theoretically, “outmoded” parts could be reused or swapped for newer parts to refurbish devices. But items that are defined as waste undergo further destruction in order to collect remaining parts and valuable metals, such as gold, silver, copper, and rare-earth elements. This process causes serious health risks to bones, brains, stomachs, lungs, and other vital organs, in addition to birth defects and disrupted biological development in children. Medical catastrophes can result from lead, cadmium, mercury, other heavy metals, poisonous fumes emitted in search of precious metals, and such carcinogenic compounds as polychlorinated biphenyls, dioxin, polyvinyl chloride, and flame retardants (Maxwell and Miller 13). The United States’ Environmental Protection Agency estimates that by 2007 US residents owned approximately three billion electronic devices, with an annual turnover rate of 400 million units, and well over half such purchases made by women. Overall CE ownership varied with age—adults under 45 typically boasted four gadgets; those over 65 made do with one. The Consumer Electronics Association (CEA) says US$145 billion was expended in the sector in 2006 in the US alone, up 13% on the previous year. The CEA refers joyously to a “consumer love affair with technology continuing at a healthy clip.” In the midst of a recession, 2009 saw $165 billion in sales, and households owned between fifteen and twenty-four gadgets on average. By 2010, US$233 billion was spent on electronic products, three-quarters of the population owned a computer, nearly half of all US adults owned an MP3 player, and 85% had a cell phone. By all measures, the amount of ICT/CE on the planet is staggering. As investigative science journalist, Elizabeth Grossman put it: “no industry pushes products into the global market on the scale that high-tech electronics does” (Maxwell and Miller 2). In 2007, “of the 2.25 million tons of TVs, cell phones and computer products ready for end-of-life management, 18% (414,000 tons) was collected for recycling and 82% (1.84 million tons) was disposed of, primarily in landfill” (Environmental Protection Agency 1). Twenty million computers fell obsolete across the US in 1998, and the rate was 130,000 a day by 2005. It has been estimated that the five hundred million personal computers discarded in the US between 1997 and 2007 contained 6.32 billion pounds of plastics, 1.58 billion pounds of lead, three million pounds of cadmium, 1.9 million pounds of chromium, and 632000 pounds of mercury (Environmental Protection Agency; Basel Action Network and Silicon Valley Toxics Coalition 6). The European Union is expected to generate upwards of twelve million tons annually by 2020 (Commission of the European Communities 17). While refrigerators and dangerous refrigerants account for the bulk of EU e-waste, about 44% of the most toxic e-waste measured in 2005 came from medium-to-small ICT/CE: computer monitors, TVs, printers, ink cartridges, telecommunications equipment, toys, tools, and anything with a circuit board (Commission of the European Communities 31-34). Understanding the enormity of the environmental problems caused by making, using, and disposing of media technologies should arrest our enthusiasm for them. But intellectual correctives to the “love affair” with technology, or technophilia, have come and gone without establishing much of a foothold against the breathtaking flood of gadgets and the propaganda that proclaims their awe-inspiring capabilities.[i] There is a peculiar enchantment with the seeming magic of wireless communication, touch-screen phones and tablets, flat-screen high-definition televisions, 3-D IMAX cinema, mobile computing, and so on—a totemic, quasi-sacred power that the historian of technology David Nye has named the technological sublime (Nye Technological Sublime 297).[ii] We demonstrate in our book why there is no place for the technological sublime in projects to green the media. But first we should explain why such symbolic power does not accrue to more mundane technologies; after all, for the time-strapped cook, a pressure cooker does truly magical things. Three important qualities endow ICT/CE with unique symbolic potency—virtuality, volume, and novelty. The technological sublime of media technology is reinforced by the “virtual nature of much of the industry’s content,” which “tends to obscure their responsibility for a vast proliferation of hardware, all with high levels of built-in obsolescence and decreasing levels of efficiency” (Boyce and Lewis 5). Planned obsolescence entered the lexicon as a new “ethics” for electrical engineering in the 1920s and ’30s, when marketers, eager to “habituate people to buying new products,” called for designs to become quickly obsolete “in efficiency, economy, style, or taste” (Grossman 7-8).[iii] This defines the short lifespan deliberately constructed for computer systems (drives, interfaces, operating systems, batteries, etc.) by making tiny improvements incompatible with existing hardware (Science and Technology Council of the American Academy of Motion Picture Arts and Sciences 33-50; Boyce and Lewis). With planned obsolescence leading to “dizzying new heights” of product replacement (Rogers 202), there is an overstated sense of the novelty and preeminence of “new” media—a “cult of the present” is particularly dazzled by the spread of electronic gadgets through globalization (Mattelart and Constantinou 22). References to the symbolic power of media technology can be found in hymnals across the internet and the halls of academe: technologies change us, the media will solve social problems or create new ones, ICTs transform work, monopoly ownership no longer matters, journalism is dead, social networking enables social revolution, and the media deliver a cleaner, post-industrial, capitalism. Here is a typical example from the twilight zone of the technological sublime (actually, the OECD): A major feature of the knowledge-based economy is the impact that ICTs have had on industrial structure, with a rapid growth of services and a relative decline of manufacturing. Services are typically less energy intensive and less polluting, so among those countries with a high and increasing share of services, we often see a declining energy intensity of production … with the emergence of the Knowledge Economy ending the old linear relationship between output and energy use (i.e. partially de-coupling growth and energy use) (Houghton 1) This statement mixes half-truths and nonsense. In reality, old-time, toxic manufacturing has moved to the Global South, where it is ascendant; pollution levels are rising worldwide; and energy consumption is accelerating in residential and institutional sectors, due almost entirely to ICT/CE usage, despite advances in energy conservation technology (a neat instance of the age-old Jevons Paradox). In our book we show how these are all outcomes of growth in ICT/CE, the foundation of the so-called knowledge-based economy. ICT/CE are misleadingly presented as having little or no material ecological impact. In the realm of everyday life, the sublime experience of electronic machinery conceals the physical work and material resources that go into them, while the technological sublime makes the idea that more-is-better palatable, axiomatic; even sexy. In this sense, the technological sublime relates to what Marx called “the Fetishism which attaches itself to the products of labour” once they are in the hands of the consumer, who lusts after them as if they were “independent beings” (77). There is a direct but unseen relationship between technology’s symbolic power and the scale of its environmental impact, which the economist Juliet Schor refers to as a “materiality paradox” —the greater the frenzy to buy goods for their transcendent or nonmaterial cultural meaning, the greater the use of material resources (40-41). We wrote Greening the Media knowing that a study of the media’s effect on the environment must work especially hard to break the enchantment that inflames popular and elite passions for media technologies. We understand that the mere mention of the political-economic arrangements that make shiny gadgets possible, or the environmental consequences of their appearance and disappearance, is bad medicine. It’s an unwelcome buzz kill—not a cool way to converse about cool stuff. But we didn’t write the book expecting to win many allies among high-tech enthusiasts and ICT/CE industry leaders. We do not dispute the importance of information and communication media in our lives and modern social systems. We are media people by profession and personal choice, and deeply immersed in the study and use of emerging media technologies. But we think it’s time for a balanced assessment with less hype and more practical understanding of the relationship of media technologies to the biosphere they inhabit. Media consumers, designers, producers, activists, researchers, and policy makers must find new and effective ways to move ICT/CE production and consumption toward ecologically sound practices. In the course of this project, we found in casual conversation, lecture halls, classroom discussions, and correspondence, consistent and increasing concern with the environmental impact of media technology, especially the deleterious effects of e-waste toxins on workers, air, water, and soil. We have learned that the grip of the technological sublime is not ironclad. Its instability provides a point of departure for investigating and criticizing the relationship between the media and the environment. The media are, and have been for a long time, intimate environmental participants. Media technologies are yesterday’s, today’s, and tomorrow’s news, but rarely in the way they should be. The prevailing myth is that the printing press, telegraph, phonograph, photograph, cinema, telephone, wireless radio, television, and internet changed the world without changing the Earth. In reality, each technology has emerged by despoiling ecosystems and exposing workers to harmful environments, a truth obscured by symbolic power and the power of moguls to set the terms by which such technologies are designed and deployed. Those who benefit from ideas of growth, progress, and convergence, who profit from high-tech innovation, monopoly, and state collusion—the military-industrial-entertainment-academic complex and multinational commandants of labor—have for too long ripped off the Earth and workers. As the current celebration of media technology inevitably winds down, perhaps it will become easier to comprehend that digital wonders come at the expense of employees and ecosystems. This will return us to Max Weber’s insistence that we understand technology in a mundane way as a “mode of processing material goods” (27). Further to understanding that ordinariness, we can turn to the pioneering conversation analyst Harvey Sacks, who noted three decades ago “the failures of technocratic dreams [:] that if only we introduced some fantastic new communication machine the world will be transformed.” Such fantasies derived from the very banality of these introductions—that every time they took place, one more “technical apparatus” was simply “being made at home with the rest of our world’ (548). Media studies can join in this repetitive banality. Or it can withdraw the welcome mat for media technologies that despoil the Earth and wreck the lives of those who make them. In our view, it’s time to green the media by greening media studies.

Theory, Culture [i] The global recession that began in 2007 has been the main reason for some declines in Global North energy consumption, slower turnover in gadget upgrades, and longer periods of consumer maintenance of electronic goods (Richtel). [ii] The emergence of the technological sublime has been attributed to the Western triumphs in the post-Second World War period, when technological power supposedly supplanted the power of nature to inspire fear and astonishment (Nye Technology Matters 28). Historian Mario Biagioli explains how the sublime permeates everyday life through technoscience: "If around 1950 the popular imaginary placed science close to the military and away from the home, today’s technoscience frames our everyday life at all levels, down to our notion of the self" (818). [iii] This compulsory repetition is seemingly undertaken each time as a novelty, governed by what German cultural critic Walter Benjamin called, in his awkward but occasionally illuminating prose, "the ever-always-the-same" of "mass-production" cloaked in "a hitherto unheard-of significance" (48).

Diaspora This article looks at diaspora through the transformations of an established public service broadcaster, the BBC World Service, by considering some of the findings of the AHRC-funded Tuning In: Contact Zones at the BBC World Service, which is part of the Diasporas, Migration and Identities program. Tuning In has six themes, each of which focuses upon the role of the BBC WS: The Politics of Translation, Diasporic Nationhood, Religious Transnationalism, Sport across Diasporas, Migrating Music and Drama for Development. The World Service, which was until 2011 funded by the Foreign Office, was set up to cater for the British diaspora and had the specific remit of transmitting ideas about Britishness to its audiences overseas. Tuning In demonstrates interrelationships between the global and the local in the diasporic contact zone of the BBC World Service, which has provided a mediated home for the worldwide British diaspora since its inception in 1932. The local and the global have merged, elided, and separated at different times and in different spaces in the changing story of the BBC (Briggs). The BBC WS is both local and global with activities that present Britishness both at home and abroad. The service has, however, come a long way since its early days as the Empire Service. Audiences for the World Service’s 31 foreign language services, radio, television, and Internet facilities include substantive non-British/English-speaking constituencies, rendering it a contact zone for the exploration of ideas and political opportunities on a truly transnational scale. This heterogeneous body of exilic, refugee intellectuals, writers, and artists now operates alongside an ongoing expression of Britishness in all its diverse reconfiguration. This includes the residual voice of empire and its patriarchal paternalism, the embrace of more recent expressions of neoliberalism as well as traditional values of impartiality and objectivism and, in the case of the arts, elements of bohemianism and creative innovation. The World Service might have begun as a communication system for the British ex-pat diaspora, but its role has changed along with the changing relationship between Britain and its colonial past. In the terrain of sport, for example, cricket, the “game of empire,” has shifted from Britain to the Indian subcontinent (Guha) with the rise of “Twenty 20” and the Indian Premier League (IPL); summed up in Ashis Nandy’s claim that “cricket is an Indian game accidentally discovered by the English” (Nandy viii). English county cricket dominated the airways of the World Service well into the latter half of the twentieth century, but the audiences of the service have demanded a response to social and cultural change and the service has responded. Sport can thus be seen to have offered a democratic space in which new diasporic relations can be forged as well as one in which colonial and patriarchal values are maintained. The BBC WS today is part of a network through which non-British diasporic peoples can reconnect with their home countries via the service, as well as an online forum for debate across the globe. In many regions of the world, it continues to be the single most trusted source of information at times of crisis and disaster because of its traditions of impartiality and objectivity, even though (as noted in the article on Al-Jazeera in this special issue) this view is hotly contested. The principles of objectivity and impartiality are central to the BBC WS, which may seem paradoxical since it is funded by the Commonwealth and Foreign office, and its origins lie in empire and colonial discourse. Archive material researched by our project demonstrates the specifically ideological role of what was first called the Empire Service. The language of empire was deployed in this early programming, and there is an explicit expression of an ideological purpose (Hill). For example, at the Imperial Conference in 1930, the service was supported in terms of its political powers of “strengthening ties” between parts of the empire. This view comes from a speech by John Reith, the BBC’s first Director General, which was broadcast when the service opened. In this speech, broadcasting is identified as having come to involve a “connecting and co-ordinating link between the scattered parts of the British Empire” (Reith). Local British values are transmitted across the globe. Through the service, empire and nation are reinstated through the routine broadcasting of cyclical events, the importance of which Scannell and Cardiff describe as follows: Nothing so well illustrates the noiseless manner in which the BBC became perhaps the central agent of national culture as its cyclical role; the cyclical production year in year out, of an orderly, regular progression of festivities, rituals and celebrations—major and minor, civic and sacred—that mark the unfolding of the broadcast year. (278; italics in the original) State occasions and big moments, including those directly concerned with governance and affairs of state, and those which focused upon sport and religion, were a big part in these “noiseless” cycles, and became key elements in the making of Britishness across the globe. The BBC is “noiseless” because the timetable is assumed and taken for granted as not only what is but what should be. However, the BBC WS has been and has had to be responsive to major shifts in global and local—and, indeed, glocal—power geometries that have led to spatial transformations, notably in the reconfiguration of the service in the era of postcolonialism. Some of these massive changes have involved the large-scale movement of people and a concomitant rethinking of diaspora as a concept. Empire, like nation, operates as an “imagined community,” too big to be grasped by individuals (Anderson), as well as a material actuality. The dynamics of identification are rarely linear and there are inconsistencies and disruptions: even when the voice is officially that of empire, the practice of the World Service is much more diverse, nuanced, and dialogical. The BBC WS challenges boundaries through the connectivities of communication and through different ways of belonging and, similarly, through a problematisation of concepts like attachment and detachment; this is most notable in the way in which programming has adapted to new diasporic audiences and in the reworkings of spatiality in the shift from empire to diversity via multiculturalism. There are tensions between diaspora and multiculturalism that are apparent in a discussion of broadcasting and communication networks. Diaspora has been distinguished by mobility and hybridity (Clifford, Hall, Bhaba, Gilroy) and it has been argued that the adjectival use of diasporic offers more opportunity for fluidity and transformation (Clifford). The concept of diaspora, as it has been used to explain the fluidity and mobility of diasporic identifications, can challenge more stabilised, “classic” understandings of diaspora (Chivallon). A hybrid version of diaspora might sit uneasily with a strong sense of belonging and with the idea that the broadcast media offer a multicultural space in which each voice can be heard and a wide range of cultures are present. Tuning In engaged with ways of rethinking the BBC’s relationship to diaspora in the twenty-first century in a number of ways: for example, in the intersection of discursive regimes of representation; in the status of public service broadcasting; vis-à-vis the consequences of diverse diasporic audiences; through the role of cultural intermediaries such as journalists and writers; and via global economic and political materialities (Gillespie, Webb and Baumann). Tuning In thus provided a multi-themed and methodologically diverse exploration of how the BBC WS is itself a series of spaces which are constitutive of the transformation of diasporic identifications. Exploring the part played by the BBC WS in changing and continuing social flows and networks involves, first, reconfiguring what is understood by transnationalism, diaspora, and postcolonial relationalities: in particular, attending to how these transform as well as sometimes reinstate colonial and patriarchal discourses and practices, thus bringing together different dimensions of the local and the global. Tuning In ranges across different fields, embracing cultural, social, and political areas of experience as represented in broadcasting coverage. These fields illustrate the educative role of the BBC and the World Service that is also linked to its particular version of impartiality; just as The Archers was set up to provide information and guidance through a narrative of everyday life to rural communities and farmers after the Second World War, so the Afghan version plays an “edutainment” role (Skuse) where entertainment also serves an educational, public service information role. Indeed, the use of soap opera genre such as The Archers as a vehicle for humanitarian and health information has been very successful over the past decade, with the “edutainment” genre becoming a feature of the World Service’s broadcasting in places such as Rwanda, Somalia, Nigeria, India, Nepal, Burma, Afghanistan, and Cambodia. In a genre that has been promoted by the World Service Trust, the charitable arm of the BBC WS uses drama formats to build transnational production relationships with media professionals and to strengthen creative capacities to undertake behaviour change through communication work. Such programming, which is in the tradition of the BBC WS, draws upon the service’s expertise and exhibits both an ideological commitment to progressive social intervention and a paternalist approach drawing upon colonialist legacies. Nowadays, however, the BBC WS can be considered a diasporic contact zone, providing sites of transnational intra-diasporic contact as well as cross-cultural encounters, spaces for cross-diasporic creativity and representation, and a forum for cross-cultural dialogue and potentially cosmopolitan translations (Pratt, Clifford). These activities are, however, still marked by historically forged asymmetric power relations, notably of colonialism, imperialism, and globalisation, as well as still being dominated by hegemonic masculinity in many parts of the service, which thus represent sites of contestation, conflict, and transgression. Conversely, diasporic identities are themselves co-shaped by media representations (Sreberny). The diasporic contact zone is a relational space in which diasporic identities are made and remade and contested. Tuning In employed a diverse range of methods to analyse the part played by the BBC WS in changing and continuing social and cultural flows, networks, and reconfigurations of transnationalisms and diaspora, as well as reinstating colonial, patriarchal practices. The research deconstructed some assumptions and conditions of class-based elitism, colonialism, and patriarchy through a range of strategies. Texts are, of course, central to this work, with the BBC Archives at Caversham (near Reading) representing the starting point for many researchers. The archive is a rich source of material for researchers which carries a vast range of data including fragile memos written on scraps of paper: a very local source of global communications. Other textual material occupies the less locatable cyberspace, for example in the case of Have Your Say exchanges on the Web. People also featured in the project, through the media, in cyberspace, and physical encounters, all of which demonstrate the diverse modes of connection that have been established. Researchers worked with the BBC WS in a variety of ways, not only through interviews and ethnographic approaches, such as participant observation and witness seminars, but also through exchanges between the service, its practitioners, and the researchers (for example, through broadcasts where the project provided the content and the ideas and researchers have been part of programs that have gone out on the BBC WS (Goldblatt, Webb), bringing together people who work for the BBC and Tuning In researchers). On this point, it should be remembered that Bush House is, itself, a diasporic space which, from its geographical location in the Strand in London, has brought together diasporic people from around the globe to establish international communication networks, and has thus become the focus and locus of some of our research. What we have understood by the term “diasporic space” in this context includes both the materialities of architecture and cyberspace which is the site of digital diasporas (Anderssen) and, indeed, the virtual exchanges featured on “Have Your Say,” the online feedback site (Tuning In). Living the Glocal The BBC WS offers a mode of communication and a series of networks that are spatially located both in the UK, through the material presence of Bush House, and abroad, through the diasporic communities constituting contemporary audiences. The service may have been set up to provide news and entertainment for the British diaspora abroad, but the transformation of the UK into a multi-ethnic society “at home,” alongside its commitment to, and the servicing of, no less than 32 countries abroad, demonstrates a new mission and a new balance of power. Different diasporic communities, such as multi-ethnic Londoners, and local and British Muslims in the north of England, demonstrate the dynamics and ambivalences of what is meant by “diaspora” today. For example, the BBC and the WS play an ambiguous role in the lives of UK Muslim communities with Pakistani connections, where consumers of the international news can feel that the BBC is complicit in the conflation of Muslims with terrorists. Engaging Diaspora Audiences demonstrated the diversity of audience reception in a climate of marginalisation, often bordering on moral panic, and showed how diasporic audiences often use Al-Jazeera or Pakistani and Urdu channels, which are seen to take up more sympathetic political positions. It seems, however, that more egalitarian conversations are becoming possible through the channels of the WS. The participation of local people in the BBC WS global project is seen, for example, as in the popular “Witness Seminars” that have both a current focus and one that is projected into the future, as in the case of the “2012 Generation” (that is, the young people who come of age in 2012, the year of the London Olympics). The Witness Seminars demonstrate the recuperation of past political and social events such as “Bangladesh in 1971” (Tuning In), “The Cold War seminar” (Tuning In) and “Diasporic Nationhood” (the cultural movements reiterated and recovered in the “Literary Lives” project (Gillespie, Baumann and Zinik). Indeed, the WS’s current focus on the “2012 Generation,” including an event in which 27 young people (each of whom speaks one of the WS languages) were invited to an open day at Bush House in 2009, vividly illustrates how things have changed. Whereas in 1948 (the last occasion when the Olympic Games were held in London), the world came to London, it is arguable that, in 2012, in contemporary multi-ethnic Britain, the world is already here (Webb). This enterprise has the advantage of giving voice to the present rather than filtering the present through the legacies of colonialism that remain a problem for the Witness Seminars more generally. The democratising possibilities of sport, as well as the restrictions of its globalising elements, are well represented by Tuning In (Woodward). Sport has, of course become more globalised, especially through the development of Internet and satellite technologies (Giulianotti) but it retains powerful local affiliations and identifications. At all levels and in diverse places, there are strong attachments to local and national teams that are constitutive of communities, including diasporic and multi-ethnic communities. Sport is both typical and distinctive of the BBC World Service; something that is part of a wider picture but also an area of experience with a life of its own. Our “Sport across Diasporas” project has thus explored some of the routes the World Service has travelled in its engagement with sport in order to provide some understanding of the legacy of empire and patriarchy, as well as engaging with the multiplicities of change in the reconstruction of Britishness. Here, it is important to recognise that what began as “BBC Sport” evolved into “World Service Sport.” Coverage of the world’s biggest sporting events was established through the 1930s to the 1960s in the development of the BBC WS. However, it is not only the global dimensions of sporting events that have been assumed; so too are national identifications. There is no question that the superiority of British/English sport is naturalised through its dominance of the BBC WS airways, but the possibilities of reinterpretation and re-accommodation have also been made possible. There has, indeed, been a changing place of sport in the BBC WS, which can only be understood with reference to wider changes in the relationship between broadcasting and sport, and demonstrates the powerful synchronies between social, political, technological, economic, and cultural factors, notably those that make up the media–sport–commerce nexus that drives so much of the trajectory of contemporary sport. Diasporic audiences shape the schedule as much as what is broadcast. There is no single voice of the BBC in sport. The BBC archive demonstrates a variety of narratives through the development and transformation of the World Service’s sports broadcasting. There are, however, silences: notably those involving women. Sport is still a patriarchal field. However, the imperial genealogies of sport are inextricably entwined with the social, political, and cultural changes taking place in the wider world. There is no detectable linear narrative but rather a series of tensions and contradictions that are reflected and reconfigured in the texts in which deliberations are made. In sport broadcasting, the relationship of the BBC WS with its listeners is, in many instances, genuinely dialogic: for example, through “Have Your Say” websites and internet forums, and some of the actors in these dialogic exchanges are the broadcasters themselves. The history of the BBC and the World Service is one which manifests a degree of autonomy and some spontaneity on the part of journalists and broadcasters. For example, in the case of the BBC WS African sports program, Fast Track (2009), many of the broadcasters interviewed report being able to cover material not technically within their brief; news journalists are able to engage with sporting events and sports journalists have covered social and political news (Woodward). Sometimes this is a matter of taking the initiative or simply of being in the right place at the right time, although this affords an agency to journalists which is increasingly unlikely in the twenty-first century. The Politics of Translation: Words and Music The World Service has played a key role as a cultural broker in the political arena through what could be construed as “educational broadcasting” via the wider terrain of the arts: for example, literature, drama, poetry, and music. Over the years, Bush House has been a home-from-home for poets: internationalists, translators from classical and modern languages, and bohemians; a constituency that, for all its cosmopolitanism, was predominantly white and male in the early days. For example, in the 1930s and 1940s, Louis MacNeice was commissioning editor and surrounded by a friendship network of salaried poets, such as W. H. Auden, Dylan Thomas, C. Day Lewis, and Stephen Spender, who wrote and performed their work for the WS. The foreign language departments of the BBC WS, meanwhile, hired émigrés and exiles from their countries’ educated elites to do similar work. The biannual, book-format journal Modern Poetry in Translation (MPT), which was founded in 1965 by Daniel Weissbort and Ted Hughes, included a dedication in Weissbort’s final issue (MPT 22, 2003) to “Poets at Bush House.” This volume amounts to a celebration of the BBC WS and its creative culture, which extended beyond the confines of broadcasting spaces. The reminiscences in “Poets at Bush House” suggest an institutional culture of informal connections and a fluidity of local exchanges that is resonant of the fluidity of the flows and networks of diaspora (Cheesman). Music, too, has distinctive characteristics that mark out this terrain on the broadcast schedule and in the culture of the BBC WS. Music is differentiated from language-centred genres, making it a particularly powerful medium of cross-cultural exchange. Music is portable and yet is marked by a cultural rootedness that may impede translation and interpretation. Music also carries ambiguities as a marker of status across borders, and it combines aesthetic intensity and diffuseness. The Migrating Music project demonstrated BBC WS mediation of music and identity flows (Toynbee). In the production and scheduling notes, issues of migration and diaspora are often addressed directly in the programming of music, while the movement of peoples is a leitmotif in all programs in which music is played and discussed. Music genres are mobile, diasporic, and can be constitutive of Paul Gilroy’s “Black Atlantic” (Gilroy), which foregrounds the itinerary of West African music to the Caribbean via the Middle Passage, cross-fertilising with European traditions in the Americas to produce blues and other hybrid forms, and the journey of these forms to Europe. The Migrating Music project focused upon the role of the BBC WS as narrator of the Black Atlantic story and of South Asian cross-over music, from bhangra to filmi, which can be situated among the South Asian diaspora in east and south Africa as well as the Caribbean where they now interact with reggae, calypso, Rapso, and Popso. The transversal flows of music and lyrics encompasses the lived experience of the different diasporas that are accommodated in the BBC WS schedules: for example, they keep alive the connection between the Irish “at home” and in the diaspora through programs featuring traditional music, further demonstrating the interconnections between local and global attachments as well as points of disconnection and contradiction. Textual analysis—including discourse analysis of presenters’ speech, program trailers and dialogue and the BBC’s own construction of “world music”—has revealed that the BBC WS itself performs a constitutive role in keeping alive these traditions. Music, too, has a range of emotional affects which are manifest in the semiotic analyses that have been conducted of recordings and performances. Further, the creative personnel who are involved in music programming, including musicians, play their own role in this ongoing process of musical migration. Once again, the networks of people involved as practitioners become central to the processes and systems through which diasporic audiences are re-produced and engaged. Conclusion The BBC WS can claim to be a global and local cultural intermediary not only because the service was set up to engage with the British diaspora in an international context but because the service, today, is demonstrably a voice that is continually negotiating multi-ethnic audiences both in the UK and across the world. At best, the World Service is a dynamic facilitator of conversations within and across diasporas: ideas are relocated, translated, and travel in different directions. The “local” of a British broadcasting service, established to promote British values across the globe, has been transformed, both through its engagements with an increasingly diverse set of diasporic audiences and through the transformations in how diasporas themselves self-define and operate. On the BBC WS, demographic, social, and cultural changes mean that the global is now to be found in the local of the UK and any simplistic separation of local and global is no longer tenable. The educative role once adopted by the BBC, and then the World Service, nevertheless still persists in other contexts (“from Ambridge to Afghanistan”), and clearly the WS still treads a dangerous path between the paternalism and patriarchy of its colonial past and its responsiveness to change. In spite of competition from television, satellite, and Internet technologies which challenge the BBC’s former hegemony, the BBC World Service continues to be a dynamic space for (re)creating and (re)instating diasporic audiences: audiences, texts, and broadcasters intersect with social, economic, political, and cultural forces. The monologic “voice of empire” has been countered and translated into the language of diversity and while, at times, the relationship between continuity and change may be seen to exist in awkward tension, it is clear that the Corporation is adapting to the needs of its twenty-first century audience.

A common criticism of the rhythm video games genre — including series like Guitar Hero and Rock Band, is that playing musical simulation games is a waste of time when you could be playing an actual guitar and learning a real skill. A more serious criticism of games cultures draws attention to the degree of e-waste they produce. E-waste or electronic waste includes mobiles phones, computers, televisions and other electronic devices, containing toxic chemicals and metals whose landfill, recycling and salvaging all produce distinct environmental and social problems. The e-waste produced by games like Guitar Hero is obvious in the regular flow of merchandise transforming computer and video games stores into simulation music stores, filled with replica guitars, drum kits, microphones and other products whose half-lives are short and whose obsolescence is anticipated in the annual cycles of consumption and disposal. This paper explores the connection between e-waste and obsolescence in the games industry, and argues for the further consideration of consumers as part of the solution to the problem of e-waste. It uses a case study of the PC digital distribution software platform, Steam, to suggest that the digital distribution of games may offer an alternative model to market driven software and hardware obsolescence, and more generally, that such software platforms might be a place to support cultures of consumption that delay rather than promote hardware obsolescence and its inevitability as e-waste. The question is whether there exists a potential for digital distribution to be a means of not only eliminating the need to physically transport commodities (its current 'green' benefit), but also for supporting consumer practices that further reduce e-waste. The games industry relies on a rapid production and innovation cycle, one that actively enforces hardware obsolescence. Current video game consoles, including the PlayStation 3, the Xbox 360 and Nintendo Wii, are the seventh generation of home gaming consoles to appear within forty years, and each generation is accompanied by an immense international transportation of games hardware, software (in various storage formats) and peripherals. Obsolescence also occurs at the software or content level and is significant because the games industry as a creative industry is dependent on the extensive management of multiple intellectual properties. The computing and video games software industry operates a close partnership with the hardware industry, and as such, software obsolescence directly contributes to hardware obsolescence. The obsolescence of content and the redundancy of the methods of policing its scarcity in the marketplace has been accelerated and altered by the processes of disintermediation with a range of outcomes (Flew). The music industry is perhaps the most advanced in terms of disintermediation with digital distribution at the center of the conflict between the legitimate and unauthorised access to intellectual property. This points to one issue with the hypothesis that digital distribution can lead to a reduction in hardware obsolescence, as the marketplace leader and key online distributor of music, Apple, is also the major producer of new media technologies and devices that are the paragon of stylistic obsolescence. Stylistic obsolescence, in which fashion changes products across seasons of consumption, has long been observed as the dominant form of scaled industrial innovation (Slade). Stylistic obsolescence is differentiated from mechanical or technological obsolescence as the deliberate supersedence of products by more advanced designs, better production techniques and other minor innovations. The line between the stylistic and technological obsolescence is not always clear, especially as reduced durability has become a powerful market strategy (Fitzpatrick). This occurs where the design of technologies is subsumed within the discourses of manufacturing, consumption and the logic of planned obsolescence in which the product or parts are intended to fail, degrade or under perform over time. It is especially the case with signature new media technologies such as laptop computers, mobile phones and portable games devices. Gamers are as guilty as other consumer groups in contributing to e-waste as participants in the industry's cycles of planned obsolescence, but some of them complicate discussions over the future of obsolescence and e-waste. Many gamers actively work to forestall the obsolescence of their games: they invest time in the play of older games (“retrogaming”) they donate labor and creative energy to the production of user-generated content as a means of sustaining involvement in gaming communities; and they produce entirely new game experiences for other users, based on existing software and hardware modifications known as 'mods'. With Guitar Hero and other 'rhythm' games it would be easy to argue that the hardware components of this genre have only one future: as waste. Alternatively, we could consider the actual lifespan of these objects (including their impact as e-waste) and the roles they play in the performances and practices of communities of gamers. For example, the Elmo Guitar Hero controller mod, the Tesla coil Guitar Hero controller interface, the Rock Band Speak n' Spellbinder mashup, the multiple and almost sacrilegious Fender guitar hero mods, the Guitar Hero Portable Turntable Mod and MAKE magazine's Trumpet Hero all indicate a significant diversity of user innovation, community formation and individual investment in the post-retail life of computer and video game hardware. Obsolescence is not just a problem for the games industry but for the computing and electronics industries more broadly as direct contributors to the social and environmental cost of electrical waste and obsolete electrical equipment. Planned obsolescence has long been the experience of gamers and computer users, as the basis of a utopian mythology of upgrades (Dovey and Kennedy). For PC users the upgrade pathway is traversed by the consumption of further hardware and software post initial purchase in a cycle of endless consumption, acquisition and waste (as older parts are replaced and eventually discarded). The accumulation and disposal of these cultural artefacts does not devalue or accrue in space or time at the same rate (Straw) and many users will persist for years, gradually upgrading and delaying obsolescence and even perpetuate the circulation of older cultural commodities. Flea markets and secondhand fairs are popular sites for the purchase of new, recent, old, and recycled computer hardware, and peripherals. Such practices and parallel markets support the strategies of 'making do' described by De Certeau, but they also continue the cycle of upgrade and obsolescence, and they are still consumed as part of the promise of the 'new', and the desire of a purchase that will finally 'fix' the users' computer in a state of completion (29). The planned obsolescence of new media technologies is common, but its success is mixed; for example, support for Microsoft's operating system Windows XP was officially withdrawn in April 2009 (Robinson), but due to the popularity in low cost PC 'netbooks' outfitted with an optimised XP operating system and a less than enthusiastic response to the 'next generation' Windows Vista, XP continues to be popular. Digital Distribution: A Solution? Gamers may be able to reduce the accumulation of e-waste by supporting the disintermediation of the games retail sector by means of online distribution. Disintermediation is the establishment of a direct relationship between the creators of content and their consumers through products and services offered by content producers (Flew 201). The move to digital distribution has already begun to reduce the need to physically handle commodities, but this currently signals only further support of planned, stylistic and technological obsolescence, increasing the rate at which the commodities for recording, storing, distributing and exhibiting digital content become e-waste. Digital distribution is sometimes overlooked as a potential means for promoting communities of user practice dedicated to e-waste reduction, at the same time it is actively employed to reduce the potential for the unregulated appropriation of content and restrict post-purchase sales through Digital Rights Management (DRM) technologies. Distributors like Amazon.com continue to pursue commercial opportunities in linking the user to digital distribution of content via exclusive hardware and software technologies. The Amazon e-book reader, the Kindle, operates via a proprietary mobile network using a commercially run version of the wireless 3G protocols. The e-book reader is heavily encrypted with Digital Rights Management (DRM) technologies and exclusive digital book formats designed to enforce current copyright restrictions and eliminate second-hand sales, lending, and further post-purchase distribution. The success of this mode of distribution is connected to Amazon's ability to tap both the mainstream market and the consumer demand for the less-than-popular; those books, movies, music and television series that may not have been 'hits' at the time of release. The desire to revisit forgotten niches, such as B-sides, comics, books, and older video games, suggests Chris Anderson, linked with so-called “long tail” economics. Recently Webb has queried the economic impact of the Long Tail as a business strategy, but does not deny the underlying dynamics, which suggest that content does not obsolesce in any straightforward way. Niche markets for older content are nourished by participatory cultures and Web 2.0 style online services. A good example of the Long Tail phenomenon is the recent case of the 1971 book A Lion Called Christian, by Anthony Burke and John Rendall, republished after the author's film of a visit to a resettled Christian in Africa was popularised on YouTube in 2008. Anderson's Long Tail theory suggests that over time a large number of items, each with unique rather than mass histories, will be subsumed as part of a larger community of consumers, including fans, collectors and everyday users with a long term interest in their use and preservation. If digital distribution platforms can reduce e-waste, they can perhaps be fostered by to ensuring digital consumers have access to morally and ethically aware consumer decisions, but also that they enjoy traditional consumer freedoms, such as the right to sell on and change or modify their property. For it is not only the fixation on the 'next generation' that contributes to obsolescence, but also technologies like DRM systems that discourage second hand sales and restrict modification. The legislative upgrades, patches and amendments to copyright law that have attempted to maintain the law's effectiveness in competing with peer-to-peer networks have supported DRM and other intellectual property enforcement technologies, despite the difficulties that owners of intellectual property have encountered with the effectiveness of DRM systems (Moore, Creative). The games industry continues to experiment with DRM, however, this industry also stands out as one of the few to have significantly incorporated the user within the official modes of production (Moore, Commonising). Is the games industry capable (or willing) of supporting a digital delivery system that attempts to minimise or even reverse software and hardware obsolescence? We can try to answer this question by looking in detail at the biggest digital distributor of PC games, Steam. Steam Figure 1: The Steam Application user interface retail section Steam is a digital distribution system designed for the Microsoft Windows operating system and operated by American video game development company and publisher, Valve Corporation. Steam combines online games retail, DRM technologies and internet-based distribution services with social networking and multiplayer features (in-game voice and text chat, user profiles, etc) and direct support for major games publishers, independent producers, and communities of user-contributors (modders). Steam, like the iTunes games store, Xbox Live and other digital distributors, provides consumers with direct digital downloads of new, recent and classic titles that can be accessed remotely by the user from any (internet equipped) location. Steam was first packaged with the physical distribution of Half Life 2 in 2004, and the platform's eventual popularity is tied to the success of that game franchise. Steam was not an optional component of the game's installation and many gamers protested in various online forums, while the platform was treated with suspicion by the global PC games press. It did not help that Steam was at launch everything that gamers take objection to: a persistent and initially 'buggy' piece of software that sits in the PC's operating system and occupies limited memory resources at the cost of hardware performance. Regular updates to the Steam software platform introduced social network features just as mainstream sites like MySpace and Facebook were emerging, and its popularity has undergone rapid subsequent growth. Steam now eclipses competitors with more than 20 million user accounts (Leahy) and Valve Corporation makes it publicly known that Steam collects large amounts of data about its users. This information is available via the public player profile in the community section of the Steam application. It includes the average number of hours the user plays per week, and can even indicate the difficulty the user has in navigating game obstacles. Valve reports on the number of users on Steam every two hours via its web site, with a population on average between one and two million simultaneous users (Valve, Steam). We know these users’ hardware profiles because Valve Corporation makes the results of its surveillance public knowledge via the Steam Hardware Survey. Valve’s hardware survey itself conceptualises obsolescence in two ways. First, it uses the results to define the 'cutting edge' of PC technologies and publishing the standards of its own high end production hardware on the companies blog. Second, the effect of the Survey is to subsequently define obsolescent hardware: for example, in the Survey results for April 2009, we can see that the slight majority of users maintain computers with two central processing units while a significant proportion (almost one third) of users still maintained much older PCs with a single CPU. Both effects of the Survey appear to be well understood by Valve: the Steam Hardware Survey automatically collects information about the community's computer hardware configurations and presents an aggregate picture of the stats on our web site. The survey helps us make better engineering and gameplay decisions, because it makes sure we're targeting machines our customers actually use, rather than measuring only against the hardware we've got in the office. We often get asked about the configuration of the machines we build around the office to do both game and Steam development. We also tend to turn over machines in the office pretty rapidly, at roughly every 18 months. (Valve, Team Fortress) Valve’s support of older hardware might counter perceptions that older PCs have no use and begins to reverse decades of opinion regarding planned and stylistic obsolescence in the PC hardware and software industries. Equally significant to the extension of the lives of older PCs is Steam's support for mods and its promotion of user generated content. By providing software for mod creation and distribution, Steam maximises what Postigo calls the development potential of fan-programmers. One of the 'payoffs' in the information/access exchange for the user with Steam is the degree to which Valve's End-User Licence Agreement (EULA) permits individuals and communities of 'modders' to appropriate its proprietary game content for use in the creation of new games and games materials for redistribution via Steam. These mods extend the play of the older games, by requiring their purchase via Steam in order for the individual user to participate in the modded experience. If Steam is able to encourage this kind of appropriation and community support for older content, then the potential exists for it to support cultures of consumption and practice of use that collaboratively maintain, extend, and prolong the life and use of games. Further, Steam incorporates the insights of “long tail” economics in a purely digital distribution model, in which the obsolescence of 'non-hit' game titles can be dramatically overturned. Published in November 2007, Unreal Tournament 3 (UT3) by Epic Games, was unappreciated in a market saturated with games in the first-person shooter genre. Epic republished UT3 on Steam 18 months later, making the game available to play for free for one weekend, followed by discounted access to new content. The 2000 per cent increase in players over the game's 'free' trial weekend, has translated into enough sales of the game for Epic to no longer consider the release a commercial failure: It’s an incredible precedent to set: making a game a success almost 18 months after a poor launch. It’s something that could only have happened now, and with a system like Steam...Something that silently updates a purchase with patches and extra content automatically, so you don’t have to make the decision to seek out some exciting new feature: it’s just there anyway. Something that, if you don’t already own it, advertises that game to you at an agreeably reduced price whenever it loads. Something that enjoys a vast community who are in turn plugged into a sea of smaller relevant communities. It’s incredibly sinister. It’s also incredibly exciting... (Meer) Clearly concerns exist about Steam's user privacy policy, but this also invites us to the think about the economic relationship between gamers and games companies as it is reconfigured through the private contractual relationship established by the EULA which accompanies the digital distribution model. The games industry has established contractual and licensing arrangements with its consumer base in order to support and reincorporate emerging trends in user generated cultures and other cultural formations within its official modes of production (Moore, "Commonising"). When we consider that Valve gets to tax sales of its virtual goods and can further sell the information farmed from its users to hardware manufacturers, it is reasonable to consider the relationship between the corporation and its gamers as exploitative. Gabe Newell, the Valve co-founder and managing director, conversely believes that people are willing to give up personal information if they feel it is being used to get better services (Leahy). If that sentiment is correct then consumers may be willing to further trade for services that can reduce obsolescence and begin to address the problems of e-waste from the ground up. Conclusion Clearly, there is a potential for digital distribution to be a means of not only eliminating the need to physically transport commodities but also supporting consumer practices that further reduce e-waste. For an industry where only a small proportion of the games made break even, the successful relaunch of older games content indicates Steam's capacity to ameliorate software obsolescence. Digital distribution extends the use of commercially released games by providing disintermediated access to older and user-generated content. For Valve, this occurs within a network of exchange as access to user-generated content, social networking services, and support for the organisation and coordination of communities of gamers is traded for user-information and repeat business. Evidence for whether this will actively translate to an equivalent decrease in the obsolescence of game hardware might be observed with indicators like the Steam Hardware Survey in the future. The degree of potential offered by digital distribution is disrupted by a range of technical, commercial and legal hurdles, primary of which is the deployment of DRM, as part of a range of techniques designed to limit consumer behaviour post purchase. While intervention in the form of legislation and radical change to the insidious nature of electronics production is crucial in order to achieve long term reduction in e-waste, the user is currently considered only in terms of 'ethical' consumption and ultimately divested of responsibility through participation in corporate, state and civil recycling and e-waste management operations. The message is either 'careful what you purchase' or 'careful how you throw it away' and, like DRM, ignores the connections between product, producer and user and the consumer support for environmentally, ethically and socially positive production, distribrution, disposal and recycling. This article, has adopted a different strategy, one that sees digital distribution platforms like Steam, as capable, if not currently active, in supporting community practices that should be seriously considered in conjunction with a range of approaches to the challenge of obsolescence and e-waste.

On 17 January 2013, Wired chose the smart contact lens as one of “7 Massive Ideas That Could Change the World” describing a Google-led research project. Wired explains that the inventor, Dr. Babak Parviz, wants to build a microsystem on a contact lens: “Using radios no wider than a few human hairs, he thinks these lenses can augment reality and incidentally eliminate the need for displays on phones, PCs, and widescreen TVs”. Explained further in other sources, the technology entails an antenna, circuits embedded into a contact lens, GPS, and an LED to project images on the eye, creating a virtual display (Solve for X). Wi-Fi would stream content through a transparent screen over the eye. One patent describes a camera embedded in the lens (Etherington). Another mentions medical sensing, such as glucose monitoring of tears (Goldman). In other words, Google proposes an imagined future when we use contact lenses to search the Internet (and be searched by it), shop online, communicate with friends, work, navigate maps, swipe through Tinder, monitor our health, watch television, and, by that time, probably engage in a host of activities not yet invented. Often referred to as a bionic contact, the smart contact lens would signal a weighty shift in the way we work, socialize, and frame our online identities. However, speculative discussion over this radical shift in personal computing, rarely if ever, includes consideration of how the body, acting as a host to digital information, will manage to assimilate not only significant affordances, but also significant constraints and vulnerabilities. At this point, for most people, the smart contact lens is just an idea. Is a new medium of communication started when it is launched in an advertising campaign? When we Like it on Facebook? If we chat about it during a party amongst friends? Or, do a critical mass of people actually have to be using it to say it has started? One might say that Apple’s Macintosh computer started as a media platform when the world heard about the famous 1984 television advertisement aired during the American NFL Super Bowl of that year. Directed by Ridley Scott, the ad entails an athlete running down a passageway and hurling a hammer at a massive screen depicting cold war style rulers expounding state propaganda. The screen explodes freeing those imprisoned from their concentration camp existence. The direct reference to Orwell’s 1984 serves as a metaphor for IBM in 1984. PC users were made analogous to political prisoners and IBM served to represent the totalitarian government. The Mac became a something that, at the time, challenged IBM, and suggested an alternative use for the desktop computer that had previously been relegated for work rather than life. Not everyone bought a Mac, but the polemical ad fostered the idea that Mac was certainly the start of new expectations, civic identities, value-systems, and personal uses for computers. The smart contact lens is another startling start. News of it shocks us, initiates social media clicks and forwards, and instigates dialogue. But, it also indicates the start of a new media paradigm that is already undergoing popular adoption as it is announced in mainstream news and circulated algorithmically across media channels. Since 2008, news outlets like CNN, The New York Times, The Globe and Mail, Asian International News, United News of India, The Times of London and The Washington Post have carried it, feeding the buzz in circulation that Google intends. Attached to the wave of current popular interest generated around any technology claiming to be “wearable,” a smart contact lens also seems surreptitious. We would no longer hold smartphones, but hide all of that digital functionality beneath our eyelids. Its emergence reveals the way commercial models have dramatically changed. The smart contact lens is a futuristic invention imagined for us and about us, but also a sensationalized idea socializing us to a future that includes it. It is also a real device that Parviz (with Google) has been inventing, promoting, and patenting for commercial applications. All of these workings speak to a broader digital culture phenomenon. We argue that the smart contact lens discloses a process of nascent posthuman adaptation, launched in an era that celebrates wearable media as simultaneously astonishing and banal. More specifically, we adopt technology based on our adaptation to it within our personal, political, medial, social, and biological contexts, which also function in a state of flux. N. Katherine Hayles writes that “Contemporary technogenesis, like evolution in general, is not about progress ... rather, contemporary technogenesis is about adaptation, the fit between organisms and their environments, recognizing that both sides of the engagement (human and technologies) are undergoing coordinated transformations” (81). This article attends to the idea that in these early stages, symbolic acts of adaptation signal an emergent medium through rhetorical processes that society both draws from and contributes to. In terms of project scope, this article contributes a focused analysis to a much larger ongoing digital rhetoric project. For the larger project, we conducted a discourse analysis on a collection of international publications concerning Babak Parviz and the invention. We searched for and collected newspaper stories, news broadcasts, YouTube videos from various sources, academic journal publications, inventors’ conference presentations, and advertising, all published between January 2008 and May 2014, generating a corpus of more than 600 relevant artifacts. Shortly after this time, Dr. Parviz, a Professor at the University of Washington, left the secretive GoogleX lab and joined Amazon.com (Mac). For this article we focus specifically on the idea of beginnings or genesis and how digital spaces increasingly serve as the grounds for emergent digital cultural phenomena that are rarely recognized as starting points. We searched through the corpus to identify a few exemplary international mainstream news stories to foreground predominant tropes in support of the claim we make that smart contacts lenses are a startling idea. Content producers deliberately use astonishment as a persuasive device. We characterize the idea of a smart contact lens cast in rhetorical terms in order to reveal how its allure works as a process of adaptation. Rhetorician and philosopher, Kenneth Burke writes that “rhetorical language is inducement to action (or to attitude)” (42). A rhetorical approach is instrumental because it offers a model to explain how we deploy, often times, manipulative meaning as senders and receivers while negotiating highly complex constellations of resources and contexts. Burke’s rhetorical theory can show how messages influence and become influenced by powerful hierarchies in discourse that seem transparent or neutral, ones that seem to fade into the background of our consciousness. For this article, we also concentrate on rhetorical devices such as ethos and the inventor’s own appeals through different modes of communication. Ethos was originally proposed by Aristotle to identify speaker credibility as a persuasive tactic. Addressed by scholars of rhetoric for centuries, ethos has been reconfigured by many critical theorists (Burke; Baumlin Ethos; Hyde). Baumlin and Baumlin suggest that “ethos describes an audience’s projection of authority and trustworthiness onto the speaker ... ethos suggests that the ethical appeal to be a radically psychological event situated in the mental processes of the audience – as belonging as much to the audience as to the actual character of a speaker” (Psychology 99). Discussed in the next section, our impression of Parviz and his position as inventor plays a dramatic role in the surfacing of the smart contact lens. Digital Rhetoric is an “emerging scholarly discipline concerned with the interpretation of computer-generated media as objects of study” (Losh 48). In an era when machine-learning algorithms become the messengers for our messages, which have become commodity items operating across globalized, capitalist networks, digital rhetoric provides a stable model for our approach. It leads us to demonstrate how this emergent medium and invention, the smart contact lens, is born amid new digital genres of speculative communication circulated in the everyday forums we engage on a daily basis. Smart Contact Lenses, Sensationalism, and Identity One relevant site for exploration into how an invention gains ethos is through writing or video penned or produced by the inventor. An article authored by Parviz in 2009 discusses his invention and the technical advancements that need to be made before the smart contact lens could work. He opens the article using a fictional and sensationalized analogy to encourage the adoption of his invention: The human eye is a perceptual powerhouse. It can see millions of colors, adjust easily to shifting light conditions, and transmit information to the brain at a rate exceeding that of a high-speed Internet connection.But why stop there?In the Terminator movies, Arnold Schwarzenegger’s character sees the world with data superimposed on his visual field—virtual captions that enhance the cyborg’s scan of a scene. In stories by the science fiction author Vernor Vinge, characters rely on electronic contact lenses, rather than smartphones or brain implants, for seamless access to information that appears right before their eyes. Identity building is made to correlate with smart contact lenses in a manner that frames them as exciting. Coming to terms with them often involves casting us as superhumans, wielding abilities that we do not currently possess. One reason for embellishment is because we do not need digital displays on the eyes, so the motive to use them must always be geared to transcending our assumed present condition as humans and society members. Consequently, imagination is used to justify a shift in human identity along a future trajectory.This passage above also instantiates a transformation from humanist to posthumanist posturing (i.e. “the cyborg”) in order to incent the adoption of smart contact lenses. It begins with the bold declarative statement, “The human eye is a perceptual powerhouse,” which is a comforting claim about our seemingly human superiority. Indexing abstract humanist values, Parviz emphasizes skills we already possess, including seeing a plethora of colours, adjusting to light on the fly, and thinking fast, indeed faster than “a high-speed Internet connection”. However, the text goes on to summon the Terminator character and his optic feats from the franchise of films. Filmic cyborg characters fulfill the excitement that posthuman rhetoric often seems to demand, but there is more here than sensationalism. Parviz raises the issue of augmenting human vision using science fiction as his contextualizing vehicle because he lacks another way to imbricate the idea. Most interesting in this passage is the inventor’s query “But why stop there?” to yoke the two claims, one biological (i.e., “The human eye is a perceptual powerhouse”) and one fictional (i.e. Terminator, Vernor Vinge characters). The query suggests, Why stop with human superiority, we may as well progress to the next level and embrace a smart contact lens just as fictional cyborgs do. The non-threatening use of fiction makes the concept seem simultaneously exciting and banal, especially because the inventor follows with a clear description of the necessary scientific engineering in the rest of the article. This rhetorical act signifies the voice of a technoelite, a heavily-funded cohort responding to global capitalist imperatives armed with a team of technologists who can access technological advancements and imbue comments with an authority that may extend beyond their fields of expertise, such as communication studies, sociology, psychology, or medicine. The result is a powerful ethos. The idea behind the smart contact lens maintains a degree of respectability long before a public is invited to use it.Parviz exhumes much cultural baggage when he brings to life the Terminator character to pitch smart contact lenses. The Terminator series of films has established the “Arnold Schwarzenegger” character a cultural mainstay. Each new film reinvented him, but ultimately promoted him within a convincing dystopian future across the whole series: The Terminator (Cameron), Terminator 2: Judgment Day (Cameron), Terminator 3: Rise of the Machines (Mostow), Terminator Salvation (McG) and Terminator Genisys (Taylor) (which appeared in 2015 after Parviz’s article). Recently, several writers have addressed how cyborg characters figure significantly in our cultural psyche (Haraway, Bukatman; Leaver). Tama Leaver’s Artificial Culture explores the way popular, contemporary, cinematic, science fiction depictions of embodied Artificial Intelligence, such as the Terminator cyborgs, “can act as a matrix which, rather than separating or demarcating minds and bodies or humanity and the digital, reinforce the symbiotic connection between people, bodies, and technologies” (31). Pointing out the violent and ultimately technophobic motive of The Terminator films, Leaver reads across them to conclude nevertheless that science fiction “proves an extremely fertile context in which to address the significance of representations of Artificial Intelligence” (63).Posthumanism and TechnogenesisOne reason this invention enters the public’s consciousness is its announcement alongside a host of other technologies, which seem like parts of a whole. We argue that this constant grouping of technologies in the news is one process indicative of technogenesis. For example, City A.M., London’s largest free commuter daily newspaper, reports on the future of business technology as a hodgepodge of what ifs: As Facebook turns ten, and with Bill Gates stepping down as Microsoft chairman, it feels like something is drawing to an end. But if so, it is only the end of the technological revolution’s beginning ... Try to look ahead ten years from now and the future is dark. Not because it is bleak, but because the sheer profusion of potential is blinding. Smartphones are set to outnumber PCs within months. After just a few more years, there are likely to be 3bn in use across the planet. In ten years, who knows – wearables? smart contact lenses? implants? And that’s just the start. The Internet of Things is projected to be a $300bn (£183bn) industry by 2020. (Sidwell) This reporting is a common means to frame the commodification of technology in globalized business news that seeks circulation as much as it does readership. But as a text, it also posits how individuals frame the future and their participation with it (Pedersen). Smart contacts appear to move along this exciting, unstoppable trajectory where the “potential is blinding”. The motive is to excite and scare. However, simultaneously, the effect is predictable. We are quite accustomed to this march of innovations that appears everyday in the morning paper. We are asked to adapt rather than question, consequently, we never separate the parts from the whole (e.g., “wearables? smart contact lenses? Implants”) in order to look at them critically.In coming to terms with Cary Wolf’s definition of posthumanism, Greg Pollock writes that posthumanism is the questioning that goes on “when we can no longer rely on ‘the human’ as an autonomous, rational being who provides an Archimedean point for knowing about the world (in contrast to “humanism,” which uses such a figure to ground further claims)” (208). With similar intent, N. Katherine Hayles formulating the term technogenesis suggests that we are not really progressing to another level of autonomous human existence when we adopt media, we are in effect, adapting to media and media are also in a process of adapting to us. She writes: As digital media, including networked and programmable desktop stations, mobile devices, and other computational media embedded in the environment, become more pervasive, they push us in the direction of faster communication, more intense and varied information streams, more integration of humans and intelligent machines, and more interactions of language with code. These environmental changes have significant neurological consequences, many of which are now becoming evident in young people and to a lesser degree in almost everyone who interacts with digital media on a regular basis. (11) Following Hayles, three actions or traits characterize adaptation in a manner germane to the technogenesis of media like smart contact lenses. The first is “media embedded in the environment”. The trait of embedding technology in the form of sensors and chips into external spaces evokes the onset of The Internet of Things (IoT) foundations. Extensive data-gathering sensors, wireless technologies, mobile and wearable components integrated with the Internet, all contribute to the IoT. Emerging from cloud computing infrastructures and data models, The IoT, in its most extreme, involves a scenario whereby people, places, animals, and objects are given unique “embedded” identifiers so that they can embark on constant data transfer over a network. In a sense, the lenses are adapted artifacts responding to a world that expects ubiquitous networked access for both humans and machines. Smart contact lenses will essentially be attached to the user who must adapt to these dynamic and heavily mediated contexts.Following closely on the first, the second point Hayles makes is “integration of humans and intelligent machines”. The camera embedded in the smart contact lens, really an adapted smartphone camera, turns the eye itself into an image capture device. By incorporating them under the eyelids, smart contact lenses signify integration in complex ways. Human-machine amalgamation follows biological, cognitive, and social contexts. Third, Hayles points to “more interactions of language with code.” We assert that with smart contact lenses, code will eventually govern interaction between countless agents in accordance with other smart devices, such as: (1) exchanges of code between people and external nonhuman networks of actors through machine algorithms and massive amalgamations of big data distributed on the Internet;(2) exchanges of code amongst people, human social actors in direct communication with each other over social media; and (3) exchanges of coding and decoding between people and their own biological processes (e.g. monitoring breathing, consuming nutrients, translating brainwaves) and phenomenological (but no less material) practices (e.g., remembering, grieving, or celebrating). The allure of the smart contact lens is the quietly pressing proposition that communication models such as these will be radically transformed because they will have to be adapted to use with the human eye, as the method of input and output of information. Focusing on genetic engineering, Eugene Thacker fittingly defines biomedia as “entail[ing] the informatic recontextualization of biological components and processes, for ends that may be medical or nonmedical (economic, technical) and with effects that are as much cultural, social, and political as they are scientific” (123). He specifies, “biomedia are not computers that simply work on or manipulate biological compounds. Rather, the aim is to provide the right conditions, such that biological life is able to demonstrate or express itself in a particular way” (123). Smart contact lenses sit on the cusp of emergence as a biomedia device that will enable us to decode bodily processes in significant new ways. The bold, technical discourse that announces it however, has not yet begun to attend to the seemingly dramatic “cultural, social, and political” effects percolating under the surface. Through technogenesis, media acclimatizes rapidly to change without establishing a logic of the consequences, nor a design plan for emergence. Following from this, we should mention issues such as the intrusion of surveillance algorithms deployed by corporations, governments, and other hegemonic entities that this invention risks. If smart contact lenses are biomedia devices inspiring us to decode bodily processes and communicate that data for analysis, for ourselves, and others in our trust (e.g., doctors, family, friends), we also need to be wary of them. David Lyon warns: Surveillance has spilled out of its old nation-state containers to become a feature of everyday life, at work, at home, at play, on the move. So far from the single all-seeing eye of Big Brother, myriad agencies now trace and track mundane activities for a plethora of purposes. Abstract data, now including video, biometric, and genetic as well as computerized administrative files, are manipulated to produce profiles and risk categories in a liquid, networked system. The point is to plan, predict, and prevent by classifying and assessing those profiles and risks. (13) In simple terms, the smart contact lens might disclose the most intimate information we possess and leave us vulnerable to profiling, tracking, and theft. Irma van der Ploeg presupposed this predicament when she wrote: “The capacity of certain technologies to change the boundary, not just between what is public and private information but, on top of that, between what is inside and outside the human body, appears to leave our normative concepts wanting” (71). The smart contact lens, with its implied motive to encode and disclose internal bodily information, needs considerations on many levels. Conclusion The smart contact lens has made a digital beginning. We accept it through the mass consumption of the idea, which acts as a rhetorical motivator for media adoption, taking place long before the device materializes in the marketplace. This occurrence may also be a sign of our “posthuman predicament” (Braidotti). We have argued that the smart contact lens concept reveals our posthuman adaptation to media rather than our reasoned acceptance or agreement with it as a logical proposition. By the time we actually squabble over the price, express fears for our privacy, and buy them, smart contact lenses will long be part of our everyday culture. References Baumlin, James S., and Tita F.

The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

This treatise investigates how information technology (I.T.) enables growth in a family business (the firm) in Port Elizabeth. The firm operates in the mobile telecommunications sector. The objective of the study is to gain a deeper understanding on why family businesses adopt information technology in their firm by means of a case study. The firm found its technology (or lack thereof) completely out-dated compared to the competition and customer demands. The future of the firm was in jeopardy. The study starts with a literature review of the following three topics which form part of the scope of the research: 1. Family businesses; 2. Influence of I.T. as a driver of growth in business; and 3. An introduction into the mobile telecommunications industry. Data are collected through structured interviews with family members involved in the business. The data are consequently linked to the theory and provides insight as to what the drivers are for I.T. adoption and the required core competencies or critical success factors of the firm. Although it might seem trivial for a small family business to adopt information technology, the research concludes that I.T. is critical for continuous growth and survival of this family business. Conversely due to a lack of internal skills the firm is heavily reliant upon outside consultants for advice, implementation and support. Recommendations which are of particular interest to family businesses in a similar environment are: • Embrace technology early, utilise I.T. solutions to grow and enhance current competitive advantage, do not see I.T. as a competitive advantage alone (Pavlou & Sawy, 2006); • If information expertise is not present within the company it is advisable to invest in that expertise through recruitment, training, partnership, or outsourcing; • Ensure software meets specification / is effective enough – this can be achieved by frequent releases cycles with small changes instead of infrequent release cycles with many big changes; • Engage the consultants in a partnership by i.e. providing a profit share – this will ensure that the consultants are committed to the cause and will also ensure that their involvement is also in their own best interest; • Choose local consultants who are easily accessible – build relationships and focus on trust; • Create lock-in (Amit & Zott, 2001), provide tools free-ofcharge for customers, this will make switching to competitor more difficult; • Automate as much as possible, enable standard work practices, routinize; • Be ready to adjust the organisational structure or relinquish control (Bruquea & Moyanob, 2007)

Thesis (Master of Engineering in Electrical Engineering)--Cape Peninsula University of Technology, 2018.<br>This research investigates and presents selected issues and aspects related to the railway mobile network (GSM-R) analysis and its shortcomings. Research studies show that millions of South Africans commuters are dependent on trains for daily movement activities, which significate contribute towards economic growth. Over the two decades, the exponential growth in wireless broadband service indicates the need for GSM-R improvement so that it can support the modern IP based protocol. The principle of implementing the digital network in railway already demonstrated significate improvement in the railway environment, especially in communication and signalling. Train traffic and train communications are the most critical aspects of railway scenarios due to safety and reliability. Both features form fundamental content to this research thesis. The exponential increase in Internet protocol (IP) based services and higher bandwidth requirements in modern technology applications have pushed the current Global system mobile for railway (GSM-R) technology to its maximum capacity as such the (GSM-R) platform is going to obsolete soon. There is a great need for the development of improved IP based networks for the future of the next generation network for fast smart trains to meet desired higher data low latency while improving quality of service (QoS). The focus of the research study is on modelling of an effective sharing method between public LTE and LTE-R without addition mobile infrastructure by utilizing train access unit (TAU), the main purpose is for public network (LTE) to handle railway emergency service including drop calls to improve quality of service (QoS). The second focus is an improvement of signal reception by spreading signals over wide spectrum range by utilizing Orthogonal variable spreading factor (OVSF) technique where LTE-R is not deployed as noted that this technique is deployed in the 3G network. The proposed scheme has adopted features in modern evolution communication and both scenarios were investigated modelled and simulated with comparison results showing better improvement in proposed conditions, there are many challenges in high-speed railway such as handover procedure and Doppler shift due to the velocity of the moving train.LTE-R has provided many solutions such as seamless handover, capacity availability as well as enhanced performance in both uplink and downlink. Digital evolution for railway GSM-R has been deployed in most developed countries in Europe and also expanded into Africa, there is a greater need for the seamless network to be developed due to an increased number of packet based services. Urban rail is the backbone of public transport in South Africa which is the Passenger Rail Agency of South Africa (PRASA). PRASA, and is the parent operator. Currently, PRASA has implemented digital railway network (GSM-R) to meet a high standard in railway. Modem demand and challenges require a cost-effective system to support IP orientated systems due to an increased number of packet-based services in the railway sectors.

The use of cellphones has increased all over the world. That invites many academics to conduct research on the usage of these devices, especially by young people, since young people join Social Network Sites (Facebook, Mxit, 2go, Whatsapp) and use a shorthand language. Most studies are related to the use of English and other languages that are recognised by computer software. There are few studies, if any, that have been done in relation to the use of African Languages on these sites. This research therefore aims to seek to explore the use of African Languages, especially isiXhosa, in assessing how technology might help in language development through the usage of SNSs that learners already use to equip them with educational material in their mother tongue. This study was conducted in two high schools, Nogemane Senior Secondary School in a disadvantaged and remote rural community with limited access to additional educational material such as magazines, newspapers, and television. The school also lacks basic study materials such as textbooks from the Education Department and they have no access to a library and laboratory. They also only have very few subjects to choose from. Nombulelo Senior Secondary School is in Grahamstown. This school has good infrastructure and learners have access to different technological devices and they can access libraries. What is common between learners in both schools is that they are all doing isiXhosa as a first language and are using SNSs to interact with each other. This study has found that learners enjoy using SNSs rather than reading the printed books. Furthermore, they enjoy and prefer interacting in isiXhosa in their conversations. Learners also use the web to post and show their creative writing, regardless of the shorthand form writing they use on the SNSs. This study has found that learners are not well equipped with basic isiXhosa skills when reaching the FET phase. They lack the understanding of standard isiXhosa idioms and proverbs. That clearly means that they are equipped in the more modern forms of literature rather than the traditional oral forms. IsiXhosa teachers also see SNSs as the better platform to engage with learners and they suggest that there must be a section in the subjects at school that teaches about cyber bullying and being safe online. This thesis also presents examples of new and contemporary forms of SNS-speak that are used by learners in both the rural and urban schools. This study is more concerned with SNSs for literacy development and to assess whether the shorthand writing has negative or positive effects in writing isiXhosa. This is done against the backdrop of a literature review which explores new literacies, computer mediated communication, social identity models as well as language policy and planning.

This dissertation examines the meanings that young adults give to their mobile phones in the township of Hooggenoeg in Grahamstown in the Eastern Cape. The research was predominantly conducted through individual interviews with nine young adults as well as two small gender-based focus groups. Participant observation as well as a close reading of the popular mobile website Outoilet also contributed to the study. Drawing on Silverstone, Hirsch and Morley’s (1992) work into the meanings attributed to the mobile phone through the domestication processes of appropriation, objectification, incorporation and conversion, the study argues for the heterogeneous roles defined for mobile phones as they are integrated into different cultural contexts. The term ‘raw phones’ in the thesis title refers to a particular cultural understanding of respectability in mainly working-class ‘coloured’¹ communities in South Africa, as described by Salo (2007) and Ross (2010), in which race, class and gender converge in the construction of the respectable person’s opposite – a lascivious, almost certainly female, dependent, black and primitive ‘raw’ Other. The study argues that in Hooggenoeg, the mobile phone becomes part of semantic processes that define both respectability and ‘rawness’ , thus helping to reproduce social relations in this community along lines of race, class and gender. A major focus of the study is the instant messaging application MXit, and how it assists in the social production of space, by helping to constitute both private and dispersed network spaces of virtual communication, in a setting where social life is otherwise very public, and social networks outside of cyberspace are densely contiguous and localised. In contrast, gossip mobile website Outoilet seems to intensify this contiguous experience of space. My findings contest generalised claims, predominantly from the developed world, which assert that the mobile phone promotes mobility and an individualised society, and show that in particular contexts it may in fact promote immobility and create a collective sociability.

The LTE is seen as the technology that will bring about Fourth Generation (4G) mobile broadband experience. The necessity to maintain quality of service for delay sensitive data services and applications used by mobile users makes mobility and handover between base stations in the downlink LTE very critical. Unfortunately, several handover schemes in LTE are based on Reference Symbols Received Power (RSRP) which include measurement error due to limited symbols in downlink packets. However, prompt and precise handover decision cannot be based on inaccurate measurement. Therefore, the downlink LTE intra-system handover is studied with focus on user measurement report. The study centers on preparation stage of the LTE handover procedure. Two different types of physical layer filtering technique namely linear averaging and local averaging are focused upon among others investigated. The performance of LTE conventional physical layer filtering technique, linear filtering, is compared with an alternative technique called local averaging. The output of each physical layer filtering is then used for LTE standardized radio resource layer filtering (otherwise called L3 filtering). The analysis of results from handover decision is based on simulations performed in an LTE system-level simulator. The performance metrics for the results are evaluated in terms of overall system and mobility-related performance. The system performance is based on spectral efficiency and throughput while mobility-related performance is based on handover failure. The performance comparison of the results shows that local averaging technique provides improved system performance of about 51.2 % for spectral efficiency and 42.8% cell-edge throughput for high speed users. Local averaging also produces a reduction of about 26.95% in average number of handover failure when L 3 filtering is applied for low speed mobile terminal. This result confirms that both averaging techniques are suitable for LTE network. Moreover, in the case of high mobility local averaging tends to be better than linear averaging.

Communication amongst field devices, control unit and programming unit in industrial automation networks is essential for bulk production, but largely consists of wired networks that can sometimes be bulky and substantially lack mobility as at times there can arise a need for a field device to be moved either for maintenance purposes or for rearrangement. There was therefore a need for wireless communication and PROFIBUS networks that can provide the minimum movement to field devices or the programing computer. Although wireless communication technology has penetrated the commercial network, it is still inadequately utilised in industrial settings due to electromagnetic induction and other forms of interferences due to industrial machinery. This dissertation introduced wireless communication in a PROFIBUS network where the MPI section was replaced with the wireless link. The PROFIBUS network technology is a hybrid of protocols where the PROFIBUS DP employs RS485 technology with a transmission rate of 45 kbps and above while the PROFIBUS PA employs Manchester Encoded Bus Powered (MBP) technology at a fixed rate of 31.25 kbps. In RS485 technology, data is transmitted as a voltage difference between the two wires while in MBP data is transmitted as transitions in current signal and data and power are transmitted on the same conductors. The PROFIBUS data is also transmitted in the form of telegrams which further puts a strain on any form of intermediate processing and hence the need for high speed processing. In this research task the PROFIBUS PA level transmitter measures the pressure of the fluid in the Blend Chest and sends it to the PLC. The level transmitter was installed and wired to the PROFIBUS DP/PA coupler. The PROFIBUS network, consisting of the PLC, variable speed drives, variable speed pumps, delivery pump and level transmitter, was configured and commissioned for controlling and monitoring from the programing computer. The program for the PLC was written using Siemens Step-7, compiled and downloaded to the PLC. The control and monitoring was done using the variable table. The wireless communication channel was then simulated using Matlab and Simulink. The wireless devices were then integrated into the PROFIBUS network and the MPI cable linking the programing computer and the PLC was then replaced by the wireless channel and the network was controlled and monitored from the programing computer over the wireless channel. On successful completion of this research task the research plant at MUT was controlled and monitored from the programing computer over the wireless channel and the researchers and demonstrators can now access the PLC and the PROFIBUS network using the wireless communication.<br>Electrical Engineering<br>M.

Submitted in fulfillment of the requirements for the degree of Master of Technology: Information Technology, Durban University of Technology, Durban, South Africa, 2015.<br>The use of mobile devices such as cell phones, smartphones, personal digital assistants and tablet computers is becoming prevalent in today’s world; and it is facilitating access to a vast amount of data, services and applications for the improvement of people’s lives. Advances in electronics and manufacturing technologies usually lead to the rapid release of newer and sleeker models with new features and capabilities. These newer models therefore render older models obsolete, and this pushes people to frequently replace their devices. The drawback of such frequent replacements is that a large number of devices are disposed and they end up as e-waste. The fact that e-waste constitutes a major hazard to human health and to the environment is the motivation behind this study whose aim is to examine the factors affecting the perceptions of teachers on the durability of cell phones in the e-learning context. This research aims was achieved through the content analysis of existing literature and through a survey of 67 secondary school teachers from the iLembe and UMgungundlovu district municipalities in the KwaZulu-Natal province of South Africa. The attribution theory was selected as the theoretical framework for this study, and it led to the identification of four independent variables (Demographics, Intention, Knowledge, and Actual use) and of one dependent variable (Perceived Durability). The results of this study indicate that teaching experience and school location are the only two demographics that affect other variables from this research: School location affects cell phone durability, and teaching experience affects cell phone usage intentions. These results also indicate that all the variables of this research are linked except for the relationship between knowledge and perceived durability. One of the recommendations of this study is the proposal of a three year cycle for cell phone renewals in schools mobile learning projects in order to manage e-waste through e-recycling, and this recommendation is based on the finding of this research that teachers believe that cell phones generally lasts between two to three years. The main contribution of this study is to have examined the durability of mobile phones in the e-learning context and this is something new compared to all the studies reviewed by this research.

This dissertation explores Mobile Media Technologies (MMT’s) namely, cellphones, laptops and MP3 players, and their prevalence in public space as well as how they are being used within the space. Much of my research analyses the impact of MMT’s on social behaviour and the extent to which they can be seen as the harbingers of a new “postmodern” form of social organisation. My research is predominantly an observational study which is conducted within the postmodern space of the shopping mall. Through my research I discuss the multiple spaces within the shopping mall environment and I explore how humans behave, interact and construct their identities within this space; these ideas are evaluated in terms of the “modern” and the “postmodern” paradigms. “Postmodernity” and “modernity” are not mutually exclusive and as a result there are ambivalences in terms of how individuals relate to how MMT’s are being used in public space.<br>Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Dissertation submitted in fulfillment of the requirements for the Degree of Master Of Technology: Marketing, Durban University Of Technology, Durban, South Africa, 2016.<br>The classical view that an industry is a customer-satisfying process and not a goods-producing process is vital for all businesses to understand. Today the mobile industry have produced a smartphone which represents a dramatic departure from traditional computing platforms as they no longer represent a static notion of context, where changes are absent, small or predictable. Therefore, today’s industries need to begin the production process with customer’s needs and not with patents, raw materials, products or selling skills. With this view rather, an organisation can only create the environment and the circumstances in which the consumer could have an experience. Furthermore, an organisation cannot grant an experience to the consumer in isolation. In seeking to expand an understating of the above classical view, this study inquired into customer experience derived from owing and using the most decorated product of the era, that is, the smartphone. The essence of this study aimed at investigating customer experience by studying smartphone usage from the students’ perspective. It studied the gap between students’ expectation and the subsequent experiences in order to determine satisfaction levels. Furthermore, cognitive dissonance was investigated to determine if there were any remorse feelings towards the smartphone. A descriptive study was employed with a quantitative inquiry and the survey used the convenience sampling method. A questionnaire was administered to students within the Durban University of Technology (DUT) fraternity. The Statistical Package for Social Science Software (SPSS) version 21 was used to analyse and to interpret the data. The key findings of the study indicate that South African university students (DUT) have positive experiences with the smartphones. Albeit, the findings indicate positive experiences, minimal presence of cognitive dissonance is also depicted. The presence of dissonance highlights that an idea cannot have a single measure which is universally meaningful. Therefore, the study expose that every product will always be exposed to suggestions of change, no matter how it can be deemed smart.<br>M
