Task-technology fit for mobile locatable information systems

To bring about intended use of a technology amongst a target user group, the technology must be a proper match with the task at hand. We learn from the fit literature that users are motivated to use a technology because they perceive it to be a better fit over and above alternative methods. This article reflects upon technological developments in information systems, particularly those that use location information as their central component for providing services. By drawing on locatability, we are able to recast the traditional fit models by differentiating between under-, over-, and ideal fit conditions. A wireless laboratory experiment with 112 subjects tests how differing fit levels impact individual performance across various tasks performed with locatable technology. For the experiment, a wireless environment is created that provides faster transmission rates and better localization accuracy than any currently existing cellular phone infrastructure. Findings conclude that subjects perceive differences between under- and ideal fit conditions when exposed to tasks that include localization components.

Transforming healthcare with information technology in Japan: A review of policy, people, and progress

PURPOSE Healthcare reform as part of the economic recovery plan in Japan is placing emphasis on the use of healthcare information technology (HIT). This research mainly focuses on the HIT efforts in Japan with reference to the US for context. The purpose is to: (a) provide detail on governmental policy impacting promotion of HIT adoption to provide services to the people of Japan, (b) describe the outcomes of past and present policy impacting progress based on a case study of HIT use in the Kyoto Yamashina area, and (c) discuss issues for refinement of current policy. METHODS The method is case study, and data collection techniques include: (a) interviews of people involved in policy making for HIT in Japan (Japanese healthcare professionals, government officials, and academics involved in HIT research in Japan) and use in the medical community of HIT in the Kyoto Yamashina area, (b) archived document analysis of reports regarding government policy for HIT policy and user assessment for HIT mainly in the case study site, and (c) the literature review about HIT progression and effectiveness assessments to explore and describe issues concerning the transformation with HIT in Japan. RESULTS This study reveals the aspects of governmental policy that have been effective in promoting successful HIT initiatives as well as some that have been detriments in Japan to help solve pressing social issues regarding healthcare delivery. For example, Japan has stipulated some standardized protocols and formats for HIT but does not mandate exactly how to engage in inter-organizational or intra-organizational health information exchange. This provides some desired autonomy for healthcare organizations and or governments in medical communities and allows for more advanced organizations to leverage current resources while providing a basis for lesser equipped organizations to use in planning the initiative. The insights gained from the Kyoto Yamashina area initiative reflect the success of past governmental policy efforts and the current intent to promote HIT adoption. Insights from the case study as well as other social issues facing Japan warrant some refinement of policy. The refinement concerns: (a) the necessity for leadership and IT knowledge in the medical communities, (b) provider incentives, (c) legislation regarding accountability, security, privacy and confidentiality, (d) inclusion of stakeholders in solution development, and (e) creating sustainable business models. CONCLUSION The research highlights the efforts of Japan for using HIT in healthcare reform. We present outcomes from a case study of the Kyoto Yamashina area medical community as proof of concept for past and present policy in Japan that are insightful for proliferation of successful projects in Japan and adoption of HIT in general.

From cacophony to harmony

HighlightsÂ? The IS implementation process contributes to organizational transformation. Â? Business process change management in essential in the IS implementation process. Â? Linking IS implementation and business strategies promotes coordination. Â? Planning strategies that stress stakeholder involvement can change culture. Â? Process-re-generation can raise the collective medical acumen to promote learning. The cacophony of criticisms emanating from an organization facing an information technology-enabled transformation can be deafening and deleterious. This is especially true in healthcare in the US, where information systems investments are typically huge and often perceived by change resistant stakeholders as disruptive or even potentially life threatening. We describe how the IS implementation process itself contributed to organizational transformation in terms of changes in coordination, culture, and learning at a successful organization, Sentara Healthcare, which transformed the discordant cacophony of the change process into a harmonious implementation.

Enriching our theoretical repertoire: the role of evolutionary psychology in technology acceptance

Information systems (IS) research has drawn heavily on social and cognitive psychology to explain technology adoption. Indeed, the many variations of the technology acceptance model all share these same theoretical foundations. Focusing exclusively on the socio-cognitive lens can lead to overlooking enhanced explanations of technology acceptance, such that new theoretical perspectives may be warranted. In this qualitative grounded theory study, we discovered how the lens of evolutionary psychology, as embodied in the Four-Drive model, was helpful in understanding technology acceptance across three organizational sites. We contend that evolutionary psychology is an important addition to the theoretical repertoire of IS researchers, and propose including ‘evolved psychological mechanisms’ within traditional models of technology acceptance.

Sustaining life during the early stages of disaster relief with a frugal information system: learning from the great east Japan earthquake

Important lessons for responding to a largescale disaster can be gleaned from the March 11, 2011 Great East Japan Earthquake and tsunami. The failure of the electrical power system and the resultant loss of information communication and processing capability severely constrained the recovery work of many municipalities. It was difficult for supporting organizations to collect and share information. A frugal information system designed around the four u-constructs is suggested as a solution for handling the very early stages of disaster relief, typically within the first 72 hours and even upon the realization of an impending disaster. This article focuses on basing communications on the most frequently available device, the cellular phone, as the foundation for a frugal IS for disaster relief. Familiar and available tools place minimal stress on an already strained communication system, and enable effective connection between those impacted by a disaster and those involved in disaster relief.

Career Choices in Information and Communication Technology among South Western Nigerian Women

This study is designed to discover the key factors for the under-representation and lack of career progression or otherwise of women in the ICT field, specifically in South Western Nigeria. Questionnaires were administered to women (i.e., students, lecturers and other staff) studying or working in selected higher institutions. The results show that 90% of the women studied are self-motivated in their choice of the ICT career with very little external incentivizing or encouragement supporting their choice, besides the lure of high compensation and prestige associated with skilled ICT work. The slight influence on the career choice of women to pursue ICT derives from everyday use of computers and career information provided by role models and mentors, which are atypical, while, those women who did not choose a career in ICT did so because of their perception of the overabundance of required programming skills. Other barriers include environmental working conditions, infrastructure and electricity in the work area needed to support ICT related work. Although, many of the career women believe that they are competitive with their male counterparts in ICT; the fact remains in South Western Nigeria that only a few women are senior associates at organizations in the ICT field. Recommendations are offered to decrease this disparity and address enabling conditions for change.

Comparative cost-benefit analysis of tele-homecare for community-dwelling elderly in Japan: Non-Government versus Government Supported Funding Models

OBJECTIVE Tele-homecare is gaining prominence as a viable care alternative, as evidenced by the increase in financial support from international governments to fund initiatives in their respective countries. The primary reason for the funding is to support efforts to reduce lags and increase capacity in access to care as well as to promote preventive measures that can avert costly emergent issues from arising. These efforts are especially important to super-aged and aging societies such as in Japan, many European countries, and the United States (US). However, to date and to our knowledge, a direct comparison of non-government vs. government-supported funding models for tele-homecare is particularly lacking in Japan. The aim of this study is to compare these operational models (i.e., non-government vs. government-supported funding) from a cost-benefit perspective. This simulation study applies to a Japanese hypothetical cohort with implications for other super-aged and aging societies abroad. METHODS We performed a cost-benefit analysis (CBA) on two operational models for enabling tele-homecare for elderly community-dwelling cohorts based on a decision tree model, which we created with parameters from published literature. The two models examined are (a) Model 1-non-government-supported funding that includes monthly fixed charges paid by users for a portion of the operating costs, and (b) Model 2-government-supported funding that includes startup and installation costs only (i.e., no operating costs) and no monthly user charges. We performed base case cost-benefit analysis and probabilistic cost-benefit analysis with a Monte Carlo simulation. We calculated net benefit and benefit-to-cost ratios (BCRs) from the societal perspective with a five-year time horizon applying a 3% discount rate for both cost and benefit values. The cost of tele-homecare included (a) the startup system expense, averaged over a five-year depreciation period, and (b) operation expenses (i.e., labor and non-labor) per user per year. The benefit of tele-homecare was measured by annual willingness to pay (WTP) for tele-homecare by a user and medical expenditures avoided. Both costs and benefits were inflated using the relevant Japanese consumer price index (CPI) and converted into 2015 US dollars with purchasing power parity (PPP) adjusted. RESULTS Base case net benefits of Model 1 and Model 2 were

97.30, respectively. Base case BCR of Model 1 tele-homecare was 1.63, while Model 2 was 1.03. The probabilistic analysis estimated mean (95%CI) for BCRs of Model 1 and Model 2 was 1.84 (1.89, 1.88) and 1.46 (1.43, 1.49), respectively. Sensitivity analysis showed robustness of Model 1 in 7 parameters but Model 2 was sensitive in all key parameters such as initial system cost, device cost, number of users, and medical expenditure saved. Break-even analysis showed that the system cost of Model 2 had to be under
