Location-Aware Mobile Media and Advertising
Authors: Wu Mei , Yao Qi
Published: August 2014

Location-Based Services (LBS) that are combined with ubiquitous smartphones usher in a new form of information propagation: Location-Based Advertising (LBA). Modern technologies enable mobile devices to generate and update location information automatically, which facilitates marketers to launch various types of location-aware advertising and promotional services to users who are in the vicinity. This chapter conceptualizes location-aware mobile communication as the locative and mobile media with a McLuhan's notion of retrieve of “locality” in the “networked” space of information flows, and examines the current dilemma faced by LBA in China through a case study. It first defines location-aware mobile technologies and influences such media afford for location-aware advertising and information propagation. It then provides an overview of the development of LBS and LBA in China. A case study of the LBA app “SBK” further offers a detailed examination how new models of advertising are developed with the technical affordances of location awareness, sociability, and spatiality. The chapter concludes with a discussion on the constraints and potential of LBA in China.

Authors: Niemelä Marketta , Kivinen Tuomo , Kulju Minna , Tammela Antti , Ikonen Veikko , Korhonen Heidi
Published: August 2014

In the context of human-driven design and environmental sustainability, the authors have developed a computer-based platform concept for studying and co-designing places (i.e. socially meaningful locations). The Visual IHME platform provides a photo-based, interactive spherical panorama environment with a set of co-creative interaction tools such as discussion boards, questionnaires, and polls on-screen. All creative content can be pinned to specific spatial spots on the image. In a preliminary end-user evaluation of the concept demonstration, the authors found that the participants valued the co-design platform, though many doubted the role of this kind of social technology in terms of real impact on issues that are important to people. They discuss how co-design platforms like Visual IHME can have an impact on environmental sustainability and the evolving role of human-computer interaction research and design in addressing sustainability problems.

Intermedia and Transmedia User Experience with Multi-Touch Apps
Authors: Kritzenberger Huberta
Published: August 2014

In the Web of devices, information and services are designed for multi-device use. As each device has its specific characteristics, inter-device adjustments and adaptations result in inconsistent inter-device (system) models. They are perceived by users on visual and functional experience layers as well as on information architecture and prevent users from building transparent mental models. Evidence from case studies reveals the nature of cognitive information processing in this situation of rich user experience. Consistency design rules seem to be insufficient to overcome the rich user experience problems, as users' exploration of inconsistencies lead to interaction problems. In consequence, a systemic intermedia perspective is needed. This is explored in this chapter.
Critical Theory, Critical Pedagogy and the Permanent Crisis in Community Colleges
Authors: Doughty Howard A.
Published: August 2014

The historical failures of Marxism in the twentieth-century came in three forms: the inability to account for the rise of fascism and Nazism; the establishment of authoritarian regimes where “communist” revolutions had occurred, largely in pre-industrial societies from barely post-feudal Russia to peasant-based China and “developing” nations such as Vietnam; and the incapacity of the proletariat to develop class consciousness and foment class conflict in advanced industrial societies, where Marx and his followers knew capitalism to have arisen and where they assumed it would first be transcended. Seeking to understand these failures, yet to preserve and apply foundational elements of Marx's thought, the “critical theorists” of the Frankfurt Institute—at home and in exile—drew on additional sources including Hegel and Freud to diagnose the pathologies of modernity, though rarely to offer restorative treatments for Enlightenment values or Marxian transformation. Jürgen Habermas, the acknowledged leader of the “second generation” of critical theorists refused to succumb to the pessimism of his elders and reached out to increasingly diverse scholars in an effort to redeem the goals of reason, democracy and equity in modern life. His theoretical work—often abstract and dense—remains almost as marginal to mainstream thought as that of Adorno and Horkheimer before him; yet, it has influenced a minority of philosophers and social scientists still interested in education as an emancipatory human project. Using the specific context of contemporary community colleges, this contribution seeks to build bridges between Habermas' combination of basically Marxian, often Kantian, and always eclectic thought to show how educators could profitably reflect upon their professional lifeworlds, better comprehend the neoliberal ideology and power relations that entrap them, and find new inspiration and advice should they wish to interrogate and confront the corporate world in which they ply their trade.
Evolving Mobile Prototypes towards the Best-Suited Design and Interaction Schema Using the Genetic Algorithm
Authors: AlTarawneh Ragaad , Humayoun Shah Rukh
Published: August 2014

The recent advances in the mobile environment, such as multi-touch gestures paradigm, introduce new challenges for the interaction designers in producing the best-suited final prototype. Moreover, the short delivery-time pressure of the current mobile market makes it harder to perform the detailed evaluations for selecting the best prototype amongst the created ones. In this vision paper, we propose an approach for evolving the created prototypes towards the final prototype with the best-suited design and interaction schema. Our approach is based on using the Genetic Algorithm for searching the best solution (prototype with the best-suited design and interaction schema) from the set of created prototypes during the design phase. The proposed approach suits the mobile application development and would enhance the interaction designers' ability of producing the final prototype of the target mobile application in an efficient and effective way.
Public Administration and Information and Communication Technologies
Authors: Virkar Shefali
Published: August 2014

This article critically examines the role of Information and Communication Technologies (ICTs) in governmental reform processes in development through a case study of the Greater Bangalore Municipal Corporation. The study explores the increasing use of ICTs for property taxation and its impact on municipal government reform processes within a developing world context. Attracted by the ‘hype and hope' of such technologies and related platforms, development actors across the world have adopted computer-based systems and related ICTs for use in government as a means reforming the inefficiencies in public service provision. Much has been written about e-governance within a growing stream of literature on ICT for development, generating countervailing perspectives where optimistic, technocratic approaches are countered by far more sceptical standpoints on technological innovation. This paper will examine not only the interplay of local contingencies and external influences acting upon the project's implementation but also aim to offer an insight into disjunctions in these relationships which inhibit the effective exploitation of ICTs in the given context. The research on which this paper is based focus on an empirical case study surrounding the implementation and use of an electronic property tax collection system in Bangalore, India between 1998 and 2008. Drawing on the theoretical perspectives of the ‘Ecology of Games' and ‘Design-Actuality Gaps' which recognise the importance of a multitude of diverse motives and individualistic behaviour as key factors influencing organisational reform and institutional change, the article contributes not just to an understanding of the role of ICTs in administrative reform in development, but towards that emerging body of research which is critical of managerial rationalism for an organization as a whole, and sensitive to an ecology of actors and their various motivations within the organisation.
Information, Innovation and the Boogeyman
Authors: Fowler Trevor , Quigley Kevin
Published: August 2014

Governments around the Western world are becoming increasingly concerned about cyber security. This paper uses the Hood et al. Risk Regulation Regime (2001) framework to describe Public Safety Canada's Cyber Security Strategy and analyze the social and economic pressures that will influence the manner in which the strategy will be operationalized. This paper recommends that government: takes a balanced approach to securing its own systems, recognizing the costs of an overly precautionary stance; continues to work and exchange information on cyber security with owners and operators of critical infrastructure while at the same time recognizing the market context in which they operate, which constrains this exchange; and helps Canadians to be secure online with enhanced public education programs that have a longer-term view and recognize people's desire for flexibility and convenience in the technology they use. The research in this paper is drawn from academic literature, media analysis and semi-structured interviews.
Patient Experiences of Diabetes eHealth
Authors: Gregory Peggy , Byrne Paula , Gabbay Mark
Published: August 2014

The authors report results from a qualitative study designed to investigate patients' use and perceptions of a diabetes eHealth system. 38 patients at a primary care practice in Northern England used a system for six months and were interviewed three times. Facilities provided were access to information; blood glucose upload and sharing; target setting; and communication with health practitioners and other patients. Results showed a variety of ‘frequency of use' and ‘features used' patterns, including non-use. Barriers included difficulty accepting diabetes, technical problems, and health or personal problems; facilitators included a positive approach to diabetes, being an established home computer user and having no additional health or personal problems. A model is presented showing how the system crosses the boundary between self-management and support seeking. The authors theorise that the system created boundary objects that take on different meanings for the actors that use them; these need to be meaningful, acceptable and engaging if the system is to be used. The authors conclude that eHealth systems would be improved by using iterative co-design and evaluation techniques to enable the capture of heterogeneous and unanticipated system use.
The Use of Information Systems in Professional Healthcare Work Practices
Authors: Svensson Ann
Published: August 2014

Over the last decades, organisations have increasingly been more knowledge intensive and professional. Professional work generally has certain specific properties related to its working context. In this paper, a case study conducted within emergency healthcare, in which professional groups like for example physicians and nurses were the objects of study, will be presented. This paper explores different characteristics of these professions in the time and life critical work practice performed within emergency healthcare. The aim of this paper is partly to analyse specific characteristics of the healthcare professions and their use of information systems, partly to identify the implications and challenges that the professions face while using information systems. Characteristics related to a certain healthcare profession can be seen as having an impact on its professionals' attitudes and use of information systems, both on an individual and on a collective level. Some challenges in the use of information systems can also be due to how the development of the system and implementation processes are organised.
IT Offshoring
Authors: Kefi Hajer , Mlaiki Alya , Peterson Richard L.
Published: August 2014

This article is about the role played by trust in structuring and shaping offshoring projects and how cultural differences interfere in the related inter-firms relationships. The study, conducted with three IT service provider companies established in Tunisia, has provided a dataset that confirms the structuring role of trust in terms of transferability effect between the client and the offshoring unit. Findings indicate that trust is perceived as an influencing factor when it is situated at the inter-organizational level and not at the interpersonal level for all the actors concerned. This finding is independent of the cultural affiliation (individualistic versus collectivist). While cultural differences are not “negotiated” the same way by all of the respondents, trust seems noticeably more difficult to settle between the Tunisian partners than between the Tunisian offshoring unit and its European clients.
