Scheduling and traffic policing for variably demanding video traffic integrated with voice and data traffic in 4th Generation wireless networks

In this paper, we present an effective mechanism for scheduling and traffic policing in 4th generation wireless networks. More specifically, we: a) extend our previous work on a Multiple Access Control (MAC) scheme for the multiplexing of voice, video and bursty data traffic over a very high-speed wireless TDMA channel, and we study our scheme's performance when MPEG-4 videoconference users of various traffic characteristics are present in the system, and b) we combine the MAC mechanism with an improved version of an efficient traffic policing mechanism. Our results are derived for cases with and without handoff traffic in the uplink channel, and it is shown that although the burstiness of MPEG-4 traffic and channel errors impedes the maximization of channel throughput, our scheme still achieves high channel throughput for all the combined voice/video/data loads examined

Street Furniture and the Nation State: A Global Process

In the popular imagination, street furniture has traditionally been understood as evoking a sense of national or local identity. From Paris’ metro entrances, DDR lampposts in Berlin, and London’s york stone pavements, the designed environment has been able to contribute to the unique qualities of a place. In some instances this was deliberate. In postwar Britain for instance, the Council of Industrial Design – a state-funded design organization - often appeared to measure the quality of street furniture on the basis of its national characteristics. On other occasions, the relationship between such objects and identity emerged accidentally. In Britain during the 1980s, for example, the replacement of Gilbert Scott's red telephone box with an alternative BT model provoked considerable debate. For many people, this act was not just a Conservative attack on nationalization and state-ownership, but also on the very fabric of British identity. This understanding of street furniture has retained its currency for many years, and cities across the world have used street furniture to provide a sense of visual coherency for neighbourhoods in need of new identities, strengthening their character and improving the public's relationship to them. In this way, street furniture has been employed as a cipher for the narrative of regeneration, in which - as a means of altering the identity of a space - street furniture can project a new face upon the street. Increasingly however, advertising companies are able to lever themselves into the street furniture market by offering to provide the service to the local authorities for free in return for advertising space. In offering this service, global companies like JC Decaux, Wall and Clear Channel command a huge amount of commercial power within the city. The excessive homogenization of street furniture coupled with the overwhelming presence of advertising which is increasingly sanctioned by local authorities keen to reduce costs, has resulted in the perception of poorer quality streets. Thus, the irony of regeneration is that by seeking to promote the unique identity of a city, many places often end up looking more and more alike. This paper will examine recent developments in the process by which the street is furnished and the agents responsible. It will specifically look at how these changes have affected the relationship between street furniture and identity, and equally the effect this process has had on understandings of national design histories. Clearly, evaluating contemporary street furniture through the lens of the nation-state is of very little value, since the international differences between street furniture are considerably less marked than they used to be. This extraordinary aesthetic convergence is partly linked to economies of scale - after all, just how many different kinds of bus stop can Europe afford to have? Yet it also reflects some of the challenges posed by globalization and privatization of public space. This paper will reflect upon that process, and how these bigger narratives increasingly affect the landscape of the street

Music and Digital Media

Anthropology has neglected the study of music. Music and Digital Media shows how and why this should be redressed. It does so by enabling music to expand the horizons of digital anthropology, demonstrating how the field can build interdisciplinary links to music and sound studies, digital/media studies, and science and technology studies. Music and Digital Media is the first comparative ethnographic study of the impact of digital media on music worldwide. It offers a radical and lucid new theoretical framework for understanding digital media through music, showing that music is today where the promises and problems of the digital assume clamouring audibility. The book contains ten chapters, eight of which present comprehensive original ethnographies; they are bookended by an authoritative introduction and a comparative postlude. Five chapters address popular, folk, art and crossover musics in the global South and North, including Kenya, Argentina, India, Canada and the UK. Three chapters bring the digital experimentally to the fore, presenting pioneering ethnographies of anextra-legal peer-to-peer site and the streaming platform Spotify, a series of prominent internet-mediated music genres, and the first ethnography of a global software package, the interactive music platform Max. The book is unique in bringing ethnographic research on popular, folk, art and crossover musics from the global North and South into a comparative framework on a large scale, and creates an innovative new paradigm for comparative anthropology. It shows how music enlarges anthropology while demanding to be understood with reference to classic themes of anthropological theory. Praise for Music and Digital Media ‘Music and Digital Media is a groundbreaking update to our understandings of sound, media, digitization, and music. Truly transdisciplinary and transnational in scope, it innovates methodologically through new models for collaboration, multi-sited ethnography, and comparative work. It also offers an important defense of—and advancement of—theories of mediation.’ Jonathan Sterne, Communication Studies and Art History, McGill University 'Music and Digital Media is a nuanced exploration of the burgeoning digital music scene across both the global North and the global South. Ethnographically rich and theoretically sophisticated, this collection will become the new standard for this field.' Anna Tsing, Anthropology, University of California at Santa Cruz 'The global drama of music's digitisation elicits extreme responses – from catastrophe to piratical opportunism – but between them lie more nuanced perspectives. This timely, absolutely necessary collection applies anthropological understanding to a deliriously immersive field, bringing welcome clarity to complex processes whose impact is felt far beyond what we call music.' David Toop, London College of Communication, musician and writer ‘Spanning continents and academic disciplines, the rich ethnographies contained in Music and Digital Media makes it obligatory reading for anyone wishing to understand the complex, contradictory, and momentous effects that digitization is having on musical cultures.’ Eric Drott, Music, University of Texas, Austin ‘This superb collection, with an authoritative overview as its introduction, represents the state of the art in studies of the digitalisation of music. It is also a testament to what anthropology at its reflexive best can offer the rest of the social sciences and humanities.’ David Hesmondhalgh, Media and Communication, University of Leeds ‘This exciting volume forges new ground in the study of local conditions, institutions, and sounds of digital music in the Global South and North. The book’s planetary scope and its commitment to the “messiness” of ethnographic sites and concepts amplifies emergent configurations and meanings of music, the digital, and the aesthetic.’ Marina Peterson, Anthropology, University of Texas, Austi

Factors Influencing Customer Satisfaction towards E-shopping in Malaysia

Online shopping or e-shopping has changed the world of business and quite a few people have decided to work with these features. What their primary concerns precisely and the responses from the globalisation are the competency of incorporation while doing their businesses. E-shopping has also increased substantially in Malaysia in recent years. The rapid increase in the e-commerce industry in Malaysia has created the demand to emphasize on how to increase customer satisfaction while operating in the e-retailing environment. It is very important that customers are satisfied with the website, or else, they would not return. Therefore, a crucial fact to look into is that companies must ensure that their customers are satisfied with their purchases that are really essential from the ecommerce’s point of view. With is in mind, this study aimed at investigating customer satisfaction towards e-shopping in Malaysia. A total of 400 questionnaires were distributed among students randomly selected from various public and private universities located within Klang valley area. Total 369 questionnaires were returned, out of which 341 questionnaires were found usable for further analysis. Finally, SEM was employed to test the hypotheses. This study found that customer satisfaction towards e-shopping in Malaysia is to a great extent influenced by ease of use, trust, design of the website, online security and e-service quality. Finally, recommendations and future study direction is provided. Keywords: E-shopping, Customer satisfaction, Trust, Online security, E-service quality, Malaysia
