Patient reactions to a web-based cardiovascular risk calculator in type 2 diabetes: a qualitative study in primary care.

Use of risk calculators for specific diseases is increasing, with an underlying assumption that they promote risk reduction as users become better informed and motivated to take preventive action. Empirical data to support this are, however, sparse and contradictory

MEASURING THE ANTECEDENT EFFECTS OF SERVICE COGNITION AND INTERNET SHOPPING ANXIETY ON CONSUMER SATISFACTION WITH E-TAILING SERVICE

Internet shopping anxiety (ISA), or the negative emotion that results from an individual’s experiences with online shopping in particular, is an important factor to explain the consumer’s emotion in ecommerce usage experience, such as e-tailing service usage experience. In this study, we introduce Internet shopping anxiety (ISA) as a new factor that reflect the consumer’s emotion in e-tailing service usage. We explore and empirically validate the relationships among Internet shopping anxiety, perceived risk and consumer satisfaction under the online retailing context. This study surveyed and collected the responses of 239 survey participants with online shopping experience. The results indicated that E-tailing service quality and trust in website have significant negative effects on Internet shopping anxiety. Further, the results showed that Internet shopping anxiety have a significant positive effect on perceived risk. Finally, perceived risk is found to have a significant negative effect on consumers’ satisfaction.consumer satisfaction, e-tailing service, internet shopping anxiety.

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users

Policy Lessons from the Fifth EWCS: The Pursuit of More and Better Jobs

[Excerpt] This report examines the evidence and policy lessons that can be drawn from the findings of the fifth European Working Conditions Survey (EWCS) carried out in 2010. The focus is on the links between working conditions and labour market participation in the light of the EU’s longstanding policy pursuit of more and better jobs. The report also assesses how the EWCS is valued by policy users and researchers, and where its further development or usage could enhance EU policy on employment and social developments. The contribution of the fifth EWCS was assessed on the basis of the mix of evidence available to policymakers, including: the extent to which EWCS data or findings are cited or used by representatives of European and national authorities, research centres and researchers; secondary analyses of EWCS data and other research which addresses current policy concerns; interviews with key users of EWCS data, especially those working in EU-level policymaking and research centres. The current economic and social policy concerns and objectives of the Europe 2020 strategy are not dramatically different from those in earlier times. However, there has been a steady increase in the level of cooperation between Member States around a mutual learning and target-based approach, supported by greater use of monitoring indicators. While the EWCS initially focused on evidence on working conditions, it has progressively developed its coverage. Today it embraces a range of issues including workplace organisation and innovation, patterns of working time and job quality. The EWCS has been particularly successful in highlighting trends, convergences and divergences through the development of indicators of policy concerns such as the quality of jobs or workplace risks (physical or psychological). It has provided new insights and understanding – often through innovative multidisciplinary research – on matters such as the relationship between different aspects of life at the workplace, and between the workplace and the household

Understanding user experience of mobile video: Framework, measurement, and optimization

Since users have become the focus of product/service design in last decade, the term User eXperience (UX) has been frequently used in the field of Human-Computer-Interaction (HCI). Research on UX facilitates a better understanding of the various aspects of the user’s interaction with the product or service. Mobile video, as a new and promising service and research field, has attracted great attention. Due to the significance of UX in the success of mobile video (Jordan, 2002), many researchers have centered on this area, examining users’ expectations, motivations, requirements, and usage context. As a result, many influencing factors have been explored (Buchinger, Kriglstein, Brandt & Hlavacs, 2011; Buchinger, Kriglstein & Hlavacs, 2009). However, a general framework for specific mobile video service is lacking for structuring such a great number of factors. To measure user experience of multimedia services such as mobile video, quality of experience (QoE) has recently become a prominent concept. In contrast to the traditionally used concept quality of service (QoS), QoE not only involves objectively measuring the delivered service but also takes into account user’s needs and desires when using the service, emphasizing the user’s overall acceptability on the service. Many QoE metrics are able to estimate the user perceived quality or acceptability of mobile video, but may be not enough accurate for the overall UX prediction due to the complexity of UX. Only a few frameworks of QoE have addressed more aspects of UX for mobile multimedia applications but need be transformed into practical measures. The challenge of optimizing UX remains adaptations to the resource constrains (e.g., network conditions, mobile device capabilities, and heterogeneous usage contexts) as well as meeting complicated user requirements (e.g., usage purposes and personal preferences). In this chapter, we investigate the existing important UX frameworks, compare their similarities and discuss some important features that fit in the mobile video service. Based on the previous research, we propose a simple UX framework for mobile video application by mapping a variety of influencing factors of UX upon a typical mobile video delivery system. Each component and its factors are explored with comprehensive literature reviews. The proposed framework may benefit in user-centred design of mobile video through taking a complete consideration of UX influences and in improvement of mobile videoservice quality by adjusting the values of certain factors to produce a positive user experience. It may also facilitate relative research in the way of locating important issues to study, clarifying research scopes, and setting up proper study procedures. We then review a great deal of research on UX measurement, including QoE metrics and QoE frameworks of mobile multimedia. Finally, we discuss how to achieve an optimal quality of user experience by focusing on the issues of various aspects of UX of mobile video. In the conclusion, we suggest some open issues for future study

Detect the unexpected: a science for surveillance

Purpose – The purpose of this paper is to outline a strategy for research development focused on addressing the neglected role of visual perception in real life tasks such as policing surveillance and command and control settings. Approach – The scale of surveillance task in modern control room is expanding as technology increases input capacity at an accelerating rate. The authors review recent literature highlighting the difficulties that apply to modern surveillance and give examples of how poor detection of the unexpected can be, and how surprising this deficit can be. Perceptual phenomena such as change blindness are linked to the perceptual processes undertaken by law-enforcement personnel. Findings – A scientific programme is outlined for how detection deficits can best be addressed in the context of a multidisciplinary collaborative agenda between researchers and practitioners. The development of a cognitive research field specifically examining the occurrence of perceptual “failures” provides an opportunity for policing agencies to relate laboratory findings in psychology to their own fields of day-to-day enquiry. Originality/value – The paper shows, with examples, where interdisciplinary research may best be focussed on evaluating practical solutions and on generating useable guidelines on procedure and practice. It also argues that these processes should be investigated in real and simulated context-specific studies to confirm the validity of the findings in these new applied scenarios

The onus on us? Stage one in developing an i-Trust model for our users.

This article describes a Joint Information Systems Committee (JISC)-funded project, conducted by a cross-disciplinary team, examining trust in information resources in the web environment employing a literature review and online Delphi study with follow-up community consultation. The project aimed to try to explain how users assess or assert trust in their use of resources in the web environment; to examine how perceptions of trust influence the behavior of information users; and to consider whether ways of asserting trust in information resources could assist the development of information literacy. A trust model was developed from the analysis of the literature and discussed in the consultation. Elements comprising the i-Trust model include external factors, internal factors and user's cognitive state. This article gives a brief overview of the JISC funded project which has now produced the i-Trust model (Pickard et. al. 2010) and focuses on issues of particular relevance for information providers and practitioners

The Influence of Website Design on Online Trust in Electronic Commerce Retailing Environments

E-commerce retail sales continue to experience significant growth in the United States (U.S.) annually. However, the contribution of e-commerce retail sales towards total retail sales in the U.S. remains low. Furthermore, the growth of e-commerce retail sales from year to year as a percentage of total retail sales in the U.S. is also fractional. The lack of online trust by consumers has been cited as a significant barrier to transacting online and a possible cause of this slow-moving trend. E-commerce retail sales are paramount to the success and profitability of online merchants. It remains critical to understand the underlying determinants of online trust as a precursor to online purchase intention. This study sought to explore the effect of one such determinant namely, website design, on online trust. Using constructs and scales synthesized from the salient literature, the effects of visual design, social-cue design, and content design on online trust were measured and reported. Additionally, the mediating influence of online trust on online purchase intention was investigated. Demographic factors of age and gender were also examined for possible moderating effects of website design on online trust. A conceptual model of the influence of website design on online trust and the influence of online trust on purchase intention in e-commerce retailing environments was also tested. The study involved scenario-based survey research methodology. Participants were presented with two websites along with a fictitious purchase scenario and post-scenario survey. The survey captured their responses with respect to the design elements of each website, their inclination to trust each website, and their intention to make a purchase from each website. Participants’ age range and gender were also captured in the survey. A total of 502 participants took part in the study. The results found that each of the components of website design namely, visual design, social-cue design, and content design had a statistically significant effect on online trust. Online trust was also found to mediate the effect of these design factors on purchase intention. Finally, no significant effects of age or gender on website design’s relationship with online trust were found. Subsequently, implications and suggestions for future research are presented

An instinct for detection: psychological perspectives on CCTV surveillance

The aim of this article is to inform and stimulate a proactive, multidisciplinary approach to research and development in surveillance-based detective work. In this article we review some of the key psychological issues and phenomena that practitioners should be aware of. We look at how human performance can be explained with reference to our biological and evolutionary legacy. We show how critical viewing conditions can be in determining whether observers detect or overlook criminal activity in video material. We examine situations where performance can be surprisingly poor, and cover situations where, even once confronted with evidence of these detection deficits, observers still underestimate their susceptibility to them. Finally we explain why the emergence of these relatively recent research themes presents an opportunity for police and law enforcement agencies to set a new, multidisciplinary research agenda focused on relevant and pressing issues of national and international importance
