This is a report on the third of our series of seminars, funded by the Economic and Social Research Council, to examine ‘The educational and social impact of new technologies on young people in Britain’. Its purpose is to bring together academics, policy makers and practitioners from many different backgrounds in order to consider the contexts and consequences of use of new information and communication technologies for children and young people, with a particular focus on the implications of technological change of formal and informal education. The first seminar scoped key theoretical frameworks, focusing on questions of age and development, on social approaches to technological change, and to diverse notions of learning. The report, titled ‘Theorising the benefits of new technology for youth: Controversies of learning and development’, can be freely downloaded from http://www.education.ox.ac.uk/ esrcseries/home/index.php. Seminar 2 concerned questions of space: we were interested in learning environments, seeking to understand how changing spatio-technical arrangements are affecting the learning environment in the classroom, school, home and community. The report, titled ‘Changing spaces: Young people...

"Digital Interactions in Developing Countries: An Economic Perspective." Jeffrey James. Routledge. January 2013. --- Challenging the existing literature by international and governmental institutions, this book looks not only at the digital divide but also at issues such as digital preparedness, leapfrogging and low-cost computers. Pietro Manzella thinks that although this book is targeted towards practitioners and experts in the field, the general reader and those grappling with this topic for the first time will also gain some valuable insights from this work.

"To Save Everything Click Here: The Folly of Technological Solutionism." Evgeny Morozov. Allen Lane. March 2013. --- Technology, Evgeny Morozov proposes, can be a force for improvement – but only if we abandon the idea that it is necessarily revolutionary and instead genuinely interrogate why and how we are using it. Alison Powell finds that although the final chapter of this book provides some examples of thoughtful ways that technology could be used as a way of thinking through problems rather than as a panacea, Morozov does not develop his critique much beyond the superficial “it’s not all about the internet.”

"Cyber War Will Not Take Place." Thomas Rid. Hurst. April 2013. --- In 2005, the U.S. Air Force boasted it would now fly, fight, and win in cyberspace, the ‘fifth domain’ of warfare. This book takes stock to consider whether or not cyber war is a real threat. Thomas Rid argues that the focus on war and winning distracts from the real challenge of cyberspace: non-violent confrontation that may rival or even replace violence in surprising ways. Tracing the most significant hacks and attacks, and exploring case studies from the world of computer espionage and weaponised code, this is an undoubtedly impressive work, writes Julia Muravska.

"Dissent and Revolution in a Digital Age: Social Media, Blogging and Activism in Egypt." David Faris. IB Tauris. March 2013. --- Dissent and Revolution in a Digital Age is essential reading for those interested in online activism, inasmuch as it provides a case study for Egypt as well as potentially for the rest of the world, writes Samaya Borom. This book tracks the rocky path taken by Egyptian bloggers operating in Mubarak s authoritarian regime to illustrate how the state monopoly on information was eroded, making space for dissent and digital activism.

"European and American Extreme Right Groups and the Internet." Manuela Caiani and Linda Parenti. Ashgate. March 2013. --- Conducting a comparative content analysis of more than 500 extreme right organizational web sites from France, Germany, Italy, Spain, the United Kingdom and the United States, this book aims to offer an overview of the Internet communication activities of these groups and systematically maps and analyses the links and structure of the virtual communities of the extreme right. The authors should be commended for producing a very coherent book on such a fluid subject, as well as for conducting a thorough examination of a large number of actors in a significant number of countries, writes Alexandros Nafpliotis.

Cloud Computing is rising fast, with its data centres growing at an unprecedented rate. However, this has come with concerns over privacy, efficiency at the expense of resilience, and environmental sus- tainability, because of the dependence on Cloud vendors such as Google, Amazon and Microsoft. Our response is an alternative model for the Cloud conceptualisation, providing a paradigm for Clouds in the com- munity, utilising networked personal computers for liberation from the centralised vendor model. Community Cloud Computing (C3) offers an alternative architecture, created by combing the Cloud with paradigms from Grid Computing, principles from Digital Ecosystems, and sustainability from Green Computing, while remaining true to the original vision of the Internet. It is more technically challenging than Cloud Computing, having to deal with distributed computing issues, including heterogeneous nodes, varying quality of service, and additional security constraints. However, these are not insurmountable challenges, and with the need to retain control over our digital lives and the potential environmental consequences, it is a challenge we must pursue.

National governments have a legitimate role to play in the development of national strategies to support electronic commerce. It is not always clear, however, what any electronic commerce legislation should incorporate or how regulation of electronic commerce should be implemented. This paper explores the strategic issues that underlie national electronic commerce strategies by following the passage of a particular piece of legislation (the UK’s Regulation of Investigatory Powers Act, 2000) through Parliament. In identifying some of the arising strains with the interests of industry and civil society, this paper will discuss some of the legal, technological, economic, and political issues that may arise in other countries as they consider the policy habitat of electronic commerce.

In Recoding Gender, Janet Abbate explores the untold history of women in computer science and programming from the Second World War to the late twentieth century. Demonstrating how gender has shaped the culture of computing, she aims to offer a valuable historical perspective on today’s concerns over women’s underrepresentation in the field. Jennifer Miller recommends this book for both readers interested in an account of women’s participation and contributions in the field of computer science and to those seeking answers to the challenges in setting policy for the scientific and technical workforce.

At a critical time of democratic reform across many parts of Southeast Asia, the suburb of Subang Jaya is regarded as Malaysia’s electronic governance laboratory. The focus of Localizing the Internet is Subang Jaya’s field of residential affairs, a digitally mediated social field in which residents, civil servants, politicians, online journalists, and other social agents struggle over how the locality is to be governed at the dawn of the Information Era. Richard Hanstock finds much of interest for sociologists, media theorists, and anthropologists.

While mainstream scientific knowledge production has been extensively examined in the academic literature, comparatively little is known about alternative networks of scientific knowledge production. Online sources such as blogs are an especially under-investigated site of knowledge contestation. Using degree centrality and node betweenness tests from social network analysis, and thematic content analysis of individual posts, this research identifies and critically examines the climate sceptical blogosphere and investigates whether a focus on particular themes contributes to the positioning of the most central blogs. A network of 171 individual blogs is identified, with three blogs in particular found to be the most central: Climate Audit, JoNova and Watts Up With That. These blogs predominantly focus on the scientific element of the climate debate, providing either a direct scientifically-based challenge to mainstream climate science, or a critique of the conduct of the climate science system. This overt scientific framing, as opposed to explicitly highlighting differences in values, politics, or ideological worldview, appears to be an important contributory factor in the positioning of the most central blogs. It is suggested that these central blogs are key protagonists in a process of attempted expert knowledge de-legitimisation and contestation...

While people have been concerned at technology’s ability to supplant human workers for hundreds of years, modern advances in computing technology mean that whole occupations may soon be made obsolete. In a study of 700 US occupations, Carl Frey and Michael Osborne find that nearly 50 percent are threatened by computerisation. They argue that the next generation of big data-driven computers will substitute low-income, low-skill workers in coming decades, and that low-skill workers will need to train in tasks that are less susceptible to computerisation if they are to remain employed.

The main contribution of this paper to current philosophical and sociological studies on modelling is to analyse modelling as an object-oriented interdisciplinary activity and thus to bring new insights into the wide, heterogeneous discourse on tools, forms and organisation of interdisciplinary research. A detailed analysis of interdisciplinarity in the making of models is presented, focusing on long-standing interdisciplinary collaboration between specialists in infectious diseases, mathematicians and computer scientists. The analysis introduces a novel way of studying the elements of the models as carriers of interdisciplinarity. These elements, being functionally interdependent building blocks, evolve during the modelling work and carry the disciplinary tensions in the process. This shows how the long and challenging process of defining and reformulating the object of research is crucial for understanding the dynamics of interdisciplinarity in the making.

Grid technologies are widely regarded as important innovations for drawing together distributed knowledge workers into virtual communities. After reviewing the developments in e-science, we examine the emergence of e-social science and its implications for information systems research practice. We consider what is new about this phenomenon and discuss the issues raised by this particular approach to the virtualization of research practices. Our analysis is organized into three sub-sections that focus on: developments in e-social science research methods; the theoretical issues involved in pursuing an e-social science agenda; as well as the status and nature of the research materials that it gives ruse to in information systems.

This panel aims to discuss concepts, assumptions and visions of user- centered information technology for healthcare. It presents two opposite views on the subject. The discussion is informed by findings of three research projects evaluating the implementation of e-prescribing systems, electronic transmission of prescriptions, and electronic health records in the UK. The timeliness and perhaps urgency of such a debate are due to the incessantly increasing worldwide computerization of healthcare, concurrent to an ambiguity of the effect of IT on care processes, outcomes and user satisfaction.

So far, digital divide research and policy was primarily engaged with access to computers and the Internet. The results of having access to these digital media were neglected. This article focuses on the tangible outcomes of online access and activity. There have been few attempts to measure such outcomes. With respect to digital inclusion, the most interesting question is who actually benefits from being online. This article answers this question by the results of a representative survey of the Dutch population in 2013. Internet outcomes and benefits are framed in concepts of participation in several domains of society: economic, social, educational, political and institutional. The results show that the same social categories having more access to the Internet also have more outcomes or benefits from Internet use: people with high education and income and young people. Outcomes in fact are the essence or stake of the digital divide. This study shows that some categories of the Dutch population benefit substantially more than others by using the Internet in finding a job, lower prices of products and services, better opportunities of education, a political party to vote for, new friends, a partner in dating and other outcomes.

This paper explores how national Electronic Patient Record (EPR) systems are customized in local settings and, in particular, how the context of their origin plays out with the context of their use. It shows how representations of healthcare organizations and of local clinical practice are built into EPR systems within a complex context whereby different stakeholder groups negotiate to produce an EPR package that aims to meet both local and generic needs. The paper draws from research into the implementation of the National Care Record Service, a part of the National Programme for Information Technology (NPfIT), in the English National Health Service (NHS). The paper makes two arguments. First, customization of national EPR is a distributed process that involves cycles of ‘translation’, which span across geographical, cultural and professional boundaries. Second, ‘translation’ is an inherently political process during which hybrid technology gets consolidated. The paper concludes, that hybrid technology opens up possibilities for standardization of healthcare.

Schelling's model of segregation looks to explain the way in which particles or agents of two types may come to arrange themselves spatially into configurations consisting of large homogeneous clusters, i.e. connected regions consisting of only one type. As one of the earliest agent based models studied by economists and perhaps the most famous model of self-organising behaviour, it also has direct links to areas at the interface between computer science and statistical mechanics, such as the Ising model and the study of contagion and cascading phenomena in networks. While the model has been extensively studied it has largely resisted rigorous analysis, prior results from the literature generally pertaining to variants of the model which are tweaked so as to be amenable to standard techniques from statistical mechanics or stochastic evolutionary game theory. In \cite{BK}, Brandt, Immorlica, Kamath and Kleinberg provided the first rigorous analysis of the unperturbed model, for a specific set of input parameters. Here we provide a rigorous analysis of the model's behaviour much more generally and establish some surprising forms of threshold behaviour, notably the existence of situations where an \emph{increased} level of intolerance for neighbouring agents of opposite type leads almost certainly to \emph{decreased} segregation.

The symbol processing or "classical cognitivist" approach to mental computation suggests that the cognitive architecture operates rather like a digital computer. The components of the architecture are input, output and central systems. The input and output systems communicate with both the internal and external environments of the cognizer and transmit codes to and from the rule governed, central processing system which operates on structured representational expressions in the internal environment. The connectionist approach, by contrast, suggests that the cognitive architecture should be thought of as a network of interconnected neuron-like processing elements (nodes) which operates rather like a brain. Connectionism distinguishes input, output and central or "hidden" layers of nodes. Connectionists claim that internal processing consists not of the rule governed manipulation of structured symbolic expressions, but of the excitation and inhibition of activity and the alteration of connection strengths via message passing within and between layers of nodes in the network. A central claim of the thesis is that neither symbol processing nor connectionism provides an adequate characterization of the role of the external environment in cognitive computation. An alternative approach...

The study of e-governance in developing nations is informed by the idea that new technologies, reshaping the very nature of public services, can generate better outcomes in their provision. Beyond objective changes in governance infrastructures, the subjective perception of the state, as it is constructed by service recipients, is exposed to a parallel process of change, whose study has generated a novel research domain in the field of egovernance for development. With a view of contributing to this domain, this thesis studies the role of ICTs in processes of image formation on the state, as experienced by citizens in a developing country context. The theory on which the thesis is developed views technology as embedded in its sociopolitical context, and conceives e-governance as implicated in the reconstruction of images of the state. This vision is applied to the computerization of the main food security programme in India, the Public Distribution System (PDS), as it has been devised and implemented in the state of Kerala. Through an interpretive case study of the object at the core of computerization, known as the Electronic Public Distribution System or e-PDS, the thesis investigates the ICT-led processes of image construction by the state...
