Shannon Vallor 《Ethics and Information Technology》2010,12(2):157-170
This paper argues in favor of more widespread and systematic applications of a virtue-based normative framework to questions
about the ethical impact of information technologies, and social networking technologies in particular. The first stage of
the argument identifies several distinctive features of virtue ethics that make it uniquely suited to the domain of IT ethics,
while remaining complementary to other normative approaches. I also note its potential to reconcile a number of significant
methodological conflicts and debates in the existing literature, including tensions between phenomenological and constructivist
perspectives. Finally, I claim that a virtue-based perspective is needed to correct for a strong utilitarian bias in the research
methodologies of existing empirical studies on the social and ethical impact of IT. The second part of the paper offers an
abbreviated demonstration of the merits of virtue ethics by showing how it might usefully illuminate the moral dimension of
emerging social networking technologies. I focus here on the potential impact of such technologies on three virtues typically
honed in communicative practices: patience, honesty and empathy. 相似文献

The Snowbird Charrette: Integrative Interdisciplinary Collaboration in Environmental Research Design
The integration of ideas, methods, and data from diverse disciplines has been a transformative force in science and higher
education, attracting policy interventions, program innovations, financial resources, and talented people. Much energy has
been invested in producing a new generation of scientists trained to work fluidly across disciplines, sectors, and research
problems, yet the success of such investments has been difficult to measure. Using the Integrative Graduate Education and
Research Training (IGERT) program of the U.S. National Science Foundation as a strategic research site, we conducted an experiment
to determine whether and how the process and products of research of IGERT-trained scientists differ from those of scientists
trained in disciplinary graduate programs. Among scientists in the early years of graduate study we found substantial and
consistent differences suggesting that interdisciplinary training improved the quality and process of research, but this pattern
was equally strongly reversed among students in the latter years of graduate study. Using systematic observation and other
data we suggest why this might be so, then discuss the implications of these results for the design and conduct of graduate
education and research. 相似文献

Construct validity evidence for single-response items to estimate physical activity levels in large sample studies 总被引:1,自引:0,他引:1

Valid measurement of physical activity is important for studying the risks for morbidity and mortality. The purpose of this study was to examine evidence of construct validity of two similar single-response items assessing physical activity via self-report. Both items are based on the stages of change model. The sample was 687 participants (men = 504, women = 183) who completed an 8-response (PA8) or 5-response (PA5) single-response item about current level of physical activity. Responses were categorized as meeting or not meeting guidelines for sufficient physical activity to achieve a health benefit. Maximal cardiorespiratory fitness (CRF) and health markers were obtained during a clinical examination. Partial correlation, multivariate analysis of covariance, and logistic regression were used to identify the relations between self-reported physical activity, CRF, and health markers when controlling for gender and age. Single-response items were compared to a detailed measure of physical activity. Single-response items correlated significantly with CRF determined with a maximal exercise test on a treadmill (PA8 = .53; PA5 = .57). Differences in percentage of body fat and cholesterol were in the desired direction, with those self-reporting sufficient physical activity for a health benefit having the lower values. The single-response items demonstrated evidence of construct validity and may provide feasible, cost-effective, and efficient methods to assess physical activity in large-scale studies. 相似文献

This teaching brief presents a capstone project designed to provide students with a contextual understanding of introductory management accounting theories through hands-on, experiential learning. It also exposes them to cross-disciplinary roles from operations management. Using this capstone approach, students quickly learn to prepare financial projections, either manually or in Microsoft Excel, to secure financing for their start-up business (Sand Art Brownie Company or SABCO) to produce and sell brownie mix during the holiday season. Students then assemble ingredients and create jars of brownie mix to gather the necessary data to evaluate initial projections and problem-solve for future production. This role play contextualizes the elements of direct and indirect labor, fixed and variable costs, and their impact on profit and borrowing. Postproduction reflection on the manufacturing activities and discussion of actual results of operations emphasizes the improvement and decision-making responsibilities in the management process. Feedback demonstrates that students find the exercise challenging and valuable and that it deepens their understanding of managerial accounting and its purpose in a company's management process. 相似文献
