College students have poor nutrition habits and often exhibit at-risk weight control behaviors; yet, health promotion efforts on campuses often target other risk behaviors such as alcohol and tobacco use. The goal of this study was to determine program content and examine the feasibility of a web-based nutrition education program for college students using innovative applications of tailoring, targeting and personalization of information. Comprehensive program planning entailed three phases: focus groups and use of concept mapping methodology, prototype web program development, and feasibility testing of the prototype. Results of concept mapping suggested that students and experts agreed on the relative importance of the major content areas unique to the college audience. A prototype web program, informed by health promotion theories, was developed and evaluated. Students and college health professionals participated in the feasibility evaluation, which included acceptance and usability testing of the prototype. Mean scores were computed for the acceptance ratings that indicated that the prototype web program was not only feasible, but also compelling and relevant for the college audience. In conclusion, a tailored, web-based interactive nutrition program could potentially be used to provide individualized nutrition information to encourage college students to adopt healthy eating behaviors.  相似文献

Individuals, families, and health care providers consider medical treatment decisions in light of their respective values about life iin varying states of health. The clarification of health care values is important not only in the context of everyday clinical decision making, but also for advance care planning and the resolution of ethical dilemmas. This article argues that objective assessment tools may facilitate the process of clarifying and communicating health care values in these contexts. The article reviews arguments for the importance of values assessment in health care planning, methods used to date for health care values assessment, conceptual and methodological challenges for the measurement of health care values, and lessons learned through the process of developing and piloting a Health Care Values Survey. Objective values assessment tools appear useful for eliciting health care values, although multiple challenges for reliable, valid, and clinically useful measurement of values are identified.  相似文献

Lower-Status Participation and Influence:Task Structure Matters   总被引:1,自引:0,他引:1  
Status hierarchies readily form in groups and , once established , limit lower-status group members' opportunities for contributing to and influencing group decisions . Recent findings , however , suggest that the type of task on which a group works may allow lower-status individuals to break through power and prestige orders in a cooperative way while conflicting with ideas of their higher-status group members . In this article , we review a research program that investigates how task structure relates to status and influence in small groups . In one experiment, using groups of three female students as participants , we found that open-structured tasks allow lower-status group members to participate , receive positive evaluations , and improve their status more than closed-structured tasks . In a second experiment, using groups of two female students and a female experimenter as participants , we found that open-structured tasks and lower-status confederates foster more divergent thinking and indirect influence than closed-structured tasks and higher-status sources . Our findings contribute to the understanding of how immediate problem-solving environments contribute to status change and influence in small groups.  相似文献

Abstract

At a time when public debates about radicalization of Muslim youth in the West are taking center stage and when questions about “home-grown” security threats are increasing in the wake of a number of terrorist attacks in many émigré societies, this article provides fresh empirical insights from the perspective of religious leadership. It outlines a picture of a highly diverse Muslim religious landscape where competing religious discourses are struggling to attract and support Muslim youth facing social dislocation and identity crises within increasingly contested social milieus. The article argues that a typology of religious leadership is clearly emerging where a spectrum of faith-based orientations and religious practice emphasize, to different degrees, notions of attachment to universal ethics and individual agency. The fact that conservative, sometimes radical, interpretations of such contestations represent a minority of voices is heartening even though the actual damage by such minority is often disproportionate to its actual size within the so-called silent majority. The empirical insights provided by the religious leaders interviewed for this study offer hope that the future of Western Muslims is more positive than we are led to think, if the possibility of combining devout faith with local political engagement becomes a real and sustainable conduit towards social inclusion and intercultural understanding and if necessary support and understanding are extended by the host communities.  相似文献

Some interventions by social workers, teachers and parents take time to develop but can produce, in the longer term, powerful and unexpectedly positive results. We were reminded of this in 2013, when we undertook a small qualitative study where we used feminist memory work to explore the experiences of 11 women from low socio-economic backgrounds studying social sciences at an Australian university. Of the eleven participants, seven were from social work. When asked to remember their journey into tertiary education, the women revealed memorable encounters with social workers, teachers and parents, the impact of which had lasted well into the future. We use the gardening metaphor of ‘planting a seed’ to refer to interventions that may not blossom in the short term but can bear fruit months or years later. Yet, we also note that ‘seeds of doubt’ can be planted too. We conclude by suggesting that planting seeds of possibility is a worthy but potentially overlooked professional activity. Yet, since ours is a small study, further research is warranted to explore the influence of social workers who plant seeds of possibility and whose actions help to recruit and retain socially disadvantaged students in higher education.  相似文献

ABSTRACT

Home visitation programs to prevent child maltreatment are offered in many communities. Agencies in these communities want to help families in need while under increased pressure to provide effective services. Funding is limited and competitive; some agencies might choose to limit funds spent on supervision, training, and evaluation as a way to provide more direct service. In this article, we use an implementation science framework and the results of an evaluation of a small home visitation program to underscore the importance of ongoing training and supervision, attention to fidelity, and program evaluation. The evaluation included 17 families entering the program during 21 months. Evaluators visited families in their homes at the beginning of the program and again 10 months later. Like many other well-intended, small-scale programs, this one “borrowed” from evidence-based models and expanded enrollment criteria in an attempt to better serve families. Findings from the evaluation suggest that the program, as it was carried out, was not effective at reducing parenting behaviors known to be associated with child maltreatment. We offer advice to funding and community agencies based on these findings and implementation science. Future evaluation research must pay greater attention to fidelity and implementation.  相似文献

The domain of risk analysis is expanded to consider strategic interactions among multiple participants in the management of extreme risk in a system of systems. These risks are fraught with complexity, ambiguity, and uncertainty, which pose challenges in how participants perceive, understand, and manage risk of extreme events. In the case of extreme events affecting a system of systems, cause‐and‐effect relationships among initiating events and losses may be difficult to ascertain due to interactions of multiple systems and participants (complexity). Moreover, selection of threats, hazards, and consequences on which to focus may be unclear or contentious to participants within multiple interacting systems (ambiguity). Finally, all types of risk, by definition, involve potential losses due to uncertain events (uncertainty). Therefore, risk analysis of extreme events affecting a system of systems should address complex, ambiguous, and uncertain aspects of extreme risk. To accomplish this, a system of systems engineering methodology for risk analysis is proposed as a general approach to address extreme risk in a system of systems. Our contribution is an integrative and adaptive systems methodology to analyze risk such that strategic interactions among multiple participants are considered. A practical application of the system of systems engineering methodology is demonstrated in part by a case study of a maritime infrastructure system of systems interface, namely, the Straits of Malacca and Singapore.  相似文献

Abstract

The libraries in the Western North Carolina Library Network (WNCLN) seek effective ways to provide patrons with a complete list of electronic journals provided through their various aggregator services, so patrons can determine e-journal access to article citations. The WNCLN libraries (Appalachian State University, the University of North Carolina at Asheville, and Western Carolina University) accomplished this through their shared catalog (Innovative Interfaces, Inc. [INNOPAC]), data provided by Serials Solutions, and local computer programming. Brief MARC records, with locally created key titles, provide an interim solution to the complexities of aggregator services. Serials Review 2002; 28:108–112.  相似文献
