Due to the complexity of emergencies, interdependencies between decisions are often neglected despite their importance. This paper aims at supporting decision makers in considering the interdependencies and addresses the problem of time: decisions depend on the time and information available, and the timing of decisions can influence on their consequences. To account for the requirements in different...
In this paper we analyze the competitive effects between mobile and fixed broadband. We use the Lotka Volterra competition model, known from ecology, to analyze these competitive effects in the OECD area. The results suggest that mobile broadband demand is stimulated by a high demand for fixed broadband services. Hence, the majority of consumers does not view fixed broadband as a substitute for mobile...
Regional and global strategies to bring the benefits of e-government to Pacific Island Countries (PICs) have been less successful than anticipated despite large amounts of aid expenditure. National policies and projects likewise struggle to overcome the barriers of geography, isolation, climate, education, language and economic resources that face all Small Island Developing States (SIDs) when implementing...
In this paper, we present a methodology to incorporate the service offered by an aggregator of longer duration deferrable loads in the Unit Commitment (UC) optimization. The description of the deferrable demand we propose is accurate, yet not computationally intensive, and can be added to any type of UC optimization so that the ISO can use time-shift able loads as an additional dispatch able resource...
Thousands of U.S. physicians have reached the first stage of "meaningful use" and received incentive payments through the HITECH Act. Yet doubts have surfaced about the sustainability of EHR diffusion, as well as about which providers will benefit from program incentives. In this paper we report the findings of a survey conducted among Hawaii physicians, in which we assessed the views of...
Suicide is an important emerging problem among active duty personnel and veterans of recent conflicts in Iraq and Afghanistan. Suicide rates among veterans treated in the VA System are about 50% higher than in the general population, and the rate of suicide among active duty service personnel has recently exceeded the rate in the general population. Preventing suicides and providing services is a...
The innovative application of information technologies (IT) in the consumer, clinical, and public health spheres offers the potential for transformational improvements to the healthcare system. Addressing the significant challenge of developing, evaluating, and integrating such innovations requires a systems approach that encompasses the technical and social dimensions, as well as interrelationships...
In the U.S., according to the American Cancer Society, there were an estimated 12,710 new cases of cervical cancer in 2011 and 4,290 women died from it [1]. It has been established that human papillomavirus (HPV) infection is a necessary cause of cervical cancer [2]. In 2006, the first HPV vaccine was approved for use with young women, however, the adoption rate remains low. To promote vaccine adoption...
Increasingly, experts and interested laypeople are turning to the explosion of online data to form and explore hypotheses about relationships between public health intervention strategies and their possible impacts. We have engaged in a multi-year collaboration to use and design semantic techniques and tools to support the current and next generation of these explorations. We introduce a tool, qb...
This paper aims to identify, explain and understand the adoption, use and diffusion of OSNs within UK's older population. This was achieved using a quantitative online survey questionnaire. Results from a sample population of 252 participants' revealed that age, gender, education, Internet usage history and usage frequencies are all associated with adoption rates. However, it was also learnt that...
This research illustrates the importance of investigating the impact of cultural influences on Internet adoption. Two constructs related to cultural identification (national and ethnic) are elaborated based on orthogonal cultural identification theory. Another construct related to acculturation to the global culture is developed to provide a dynamic view of culture. Members of two different ethnic...
Concerns have been raised about the decreased ability of Wikipedia to recruit editors and in to harness the effort of contributors to create new articles and improve existing articles. But, as Mar well and Oliver explained explained, in collective projects, in the initial stage of the project, people are few and efforts costly, in the diffusion phase, the number of participants grows as their efforts...
Reconnecting with past relationships is documented as one of the main motivations for using Social Network Sites (SNSs) such as Facebook. Numerous studies underline the ways SNSs may support social interactions in the broad context of the offline-and-online seamless web. However, in the author's knowledge, no studies have been conducted to link these two aspects, and very little research addresses...
We are seeing more and more organizations undertaking activities to engage dispersed populations through IS. Using the knowledge-based view of the organization, this work conceptualizes a theory of Crowd Capital to explain this phenomenon. Crowd Capital is a heterogeneous knowledge resource generated by an organization, through its use of Crowd Capability, which is defined by the structure, content,...
Little research data exist about agile teams and wellbeing. After changing our software engineering mode to agile, we wanted to find out if people experienced more or less stress than before. This study is based on a company-wide survey of 466 software engineering practitioners. We asked about their subjective feelings about stress, empowerment, and performance in their respective engineering teams...
