Towards successful e-Payment systems: An empirical identification and analysis of critical factors
This research aims to explore the factors relating to e-payment system to be implemented where electronic processes enable the facilitation of online transactions. A secondary analysis revealed six factors which are argued to be ‘critical’ for customer adoption of these systems. The findings were further augmented by an online survey of 155 respondents where the perceived importance of the critical factors were correlated through: security, trust, perceived advantage, assurance seals, perceived risk and usability. The results demonstrate that three of the critical factors were necessary (security, advantage, web assurance seals) and three were relatively sufficient (perceived risk, trust and usability) through customer intentions to adopt an e-payment system. The study provides a valid overall awareness that these critical factors are important in designing a successful e-payment system
Understanding digital eco-innovation in municipalities: An institutional perspective
Municipalities consume over 67% of global energy and are responsible for over 70% of greenhouse gas emissions (GHG). The Intergovernmental Panel on Climate Change warns that rapid adjustments need to happen at a global level, or the effects of climate change will be irreversible. The contribution of municipalities is therefore vital if GHG emissions are to be reduced. Our research is timely in its exploration of the ways in which municipalities institutionalise environmental sustainability practices in and through Green digital artefacts. Using mechanism-based institutional theory as a lens, the paper presents the findings of three contrasting case studies of large municipalities in the United Kingdom in their respective programmes to leverage the direct, enabling and systemic effects of Green ICT in order to reduce GHG emission and achieve their eco-sustainability goals. The case sites are also regarded as exemplars for further research and practice on digital eco-innovation. The mechanism-based explanations illustrate how a social web of conditions and factors influence eco-sustainability outcomes. We conclude that the digital technology-enabled grassroots-based initiatives offer the best hope to begin the transition to sustainable climate change within municipalities. The contributions of our study are therefore both theoretical and practical
Socio-technical transitions towards environmental sustainability through green ICT
We adopt the broad conceptualisation of Green Information Communication Technology (ICT) used by the Organisation for Economic Cooperation and Development (OECD), incorporating perspectives on Information Technology (IT) and Information Systems (IS) which has currency with both business practitioners and policy makers. The objective of our research is to develop a theory of the institutional mechanisms that underpin socio-technical transitions to environmental sustainability through the direct, indirect and systematic effects of Green ICT in and across organisational fields. We construct our theory by drawing on published research in several disciplines focusing on the organisational field of the ICT industry. We present a mechanism-based theoretical model that explains how institutional change in organisational fields can evoke appropriate socio-technical transitions and organisational responses to Green ICT. Systems researchers agree that Green ICT can help lower GHG emissions directly, through energy efficiencies and indirectly by enabling environmentally sustainable business processes. If this research is to be of theoretical or practical relevance it must recognize that government organizations and business enterprises may not adopt policies and strategies on Green ICT because it is rational or moral to do so rather, a web of social, and institutional mechanisms interact to produce the outcomes observed in practice
Challenges for ‘Green IT’ in the Scottish ADM industry
Our research reports specifically on the challenges and behaviours towards ‘Green IT’ experienced within one complex industry. We adopt a theoretical stance based upon Unified Theory of Acceptance and Use of Technology (UTAUT) to formulate an outline ‘Green IT’ agenda. We draw on historical thinking which underpins UTAUT, which can be traced back to the theory of reasoned action (TRA) and the frequently adopted technology acceptance model (TAM). Recent research on the business case for a green IT strategy identifies benefits to an enterprise’s revenue and/or cost rather than just its image making. In this respect, empirical evidence was collected and analysed from the Aerospace, Defence and Marine (ADM) industry in Scotland which includes over 800 companies employing nearly 40,000 staff which creates Gross Value Adding to the Scottish economy of around £2 billion. Data collection involved an on-line based semi structured questionnaire to all 180 Aerospace and Defence organisations using the Scottish Enterprise Database. Our findings suggest a need to develop unified measurements to evaluate green IT progress. Specifically, these should include a metric capable of measuring IT companies’ net environmental activism, assessing not only the impact of changes but also on the operations and products of their clients

An investigation of knowledge brokering during service encounters
Service encounters present excellent opportunities for obtaining and exchanging so called tacit and explicit knowledge between customers and organisations. Recently, the role of frontline employees as knowledge brokers between organisations and their customers has received attention from scholars and practitioners. Despite the significant role played by frontline employees in obtaining knowledge from customers and sharing it during service encounters, there is a lack of research that provides a comprehensive framework intended to explain their role during such engagements. Following an extensive literature review we developed a research model that identifies (1) the role of frontline employees as knowledge brokers for customers and organisations and (2) the factors that influence their roles as knowledge brokers during service encounters. In total, thirty (30) semi-structured interviews with different informants (i.e. managers and employees) from three top commercial banks in Jordan(X, Y, Z) were administered through three case studies. We adopted a qualitative ‘interpretative’ methodological approach to the analysis of the empirical data. Our findings from an evidence-based analysis suggest that the knowledge brokering engaged in by frontline employees during service encounters is affected by four sets of factors (organisational–level, individual-level, technology-level, and knowledge–level)
Evaluating Digital Public Services: a contingency value approach within three exemplar developing countries
This paper considers recent field evidence to analyse what online public services citizens need, explores potential citizen subsidy of these specific services and investigates where resources should be invested in terms of media accessibility. We explore these from a citizen-centric affordability perspective within three ‘exemplar’ developing countries in sub-Saharan Africa. The World Bank and United Nations in particular promote initiatives under the ‘Information and Communication Technologies for Development’ (ICT4D) to stress the relevance of e-Government as a way to ensure development and reduce poverty. We adopt a ‘Contingency Value’ method to conceptually outline reported citizens willingness to pay for digital public services. Hence, our focus is mainly upon an empirical investigation through extensive fieldwork in the context of sub-Sahara Africa. A substantive survey was conducted in the respective cities of Addis Ababa (Ethiopia), Lagos (Nigeria) and Johannesburg (South Africa). The sample of citizens was drawn from each respective Chamber of Commerce database for Ethiopia and South Africa, and for Nigeria a purchased database of businesses, based on stratified random sampling. These were randomly identified from both sectors ensuring all locations were covered with a total sample size of 1,297 respondents. It was found, in particular, that citizens were willing to pay to be able to access digital public services and that amounts of fees they were willing to pay varied depending on what services they wish to access and what devices they use (PCs or mobile phones)
Effective Organizational Improvision in Information Systems Development: insights from Tencent messaging system development
Organizational improvisation has been increasingly observed in information systems
development (ISD), which leads to both positive and negative results. Extant studies have examined how to conduct effective improvisation, but findings are mainly based on variancebased
models; a process model is missing. Our study fills this gap by conducting an in-depth
case study of the Tencent messaging system development. Our study identifies a four-phase
process model featuring a continuous iteration between improvisational search and build. Our
findings make important contributions to organizational improvisation literature in ISD and
general management and provide a step-by-step guide for ISD managers to conduct effective
improvisation.National Natural Science Foundation of China & Fundamental Research Funds for Central Universitie
Is there adaptation in the ozone mortality relationship: A multi-city case-crossover analysis
<p>Abstract</p> <p>Background</p> <p>Ozone has been associated with daily mortality, mainly in the summer period. Despite the ample literature on adaptation of inflammatory and pulmonary responses to ozone, and the link, in cohort studies, between lung function and mortality risk there has been little done to date to examine the question of adaptation in the acute mortality risk associated with ambient ozone.</p> <p>Methods</p> <p>We applied a case-crossover design in 48 US cities to examine the ozone effect by season, by month and by age groups, particularly focusing on whether there was an adaptation effect.</p> <p>Results</p> <p>We found that the same day ozone effect was highest in summer with a 0.5% (95% CI: 0.38, 0.62) increase in total mortality for 10 ppb increase in 8-hr ozone, whilst the effect decrease to null in autumn and winter. We found higher effects in the months May- July with a 0.46% (95% CI: 0.24, 0.68) increase in total mortality for 10 ppb increase in ozone in June, and a 0.65% (95% CI: 0.47, 0.82) increase in mortality during July. The effect decreased in August and became null in September. We found similar effects from the age group 51–60 up to age 80 and a lower effect in 80 years and older.</p> <p>Conclusion</p> <p>The mortality effects of ozone appear diminished later in the ozone season, reaching the null effect previously reported in winter by September. More work should address this issue and examine the biological mechanism of adaptation.</p
