Two problems are always present in any research: reliability and validity, and this paper will attempt to assess reliability and validity in relation to dietary data. Reliability means stability of results over a period of time or in similar situations. (It is very difficult to find two identical situations, especially outside a laboratory, as some variation is always introduced.) Validity refers to the accuracy of techniques and results. It includes the idea of measuring methods and results against a standard or criterion.  相似文献

Serials Review visits the United States Book Exchange in Cleveland, Ohio. The staff of this nonprofit organization supplies back issues to over 2,000 member libraries in addition to nonmember libraries in the United States and the world. The tour will examine how this exchange is organized and how electronic access to journal literature has changed its emphasis. Serials Review 29:318–320.  相似文献

Prosocial behaviors are a diverse group of actions that are integral to human social life. In this study, we examined the ability of 18‐ and 24‐month‐old infants to engage in three types of other‐oriented behaviors, specifically helping, sharing, and comforting. Infants in both age groups engaged in more prosocial behavior on trials in which an unfamiliar adult experimenter required aid (experimental conditions) than on those in which she did not (control conditions) across two of the three prosocial tasks (i.e., helping and sharing). The infants engaged in these behaviors with similar frequency; however, there was no correlation between the tasks. The implications for the construct of prosocial behavior and the presence of a prosocial disposition are discussed.  相似文献

Abstract

College students' cigarette smoking rose dramatically during the 1990s. Little is known about what colleges do to address the problem. Health center directors at 393 4-year US colleges provided information (response rate: 65.1%) about college policies addressing smoking and the availability of smoking cessation programs. Of the health center directors surveyed, 85% considered students' smoking a problem; yet only 81% of colleges prohibit smoking in all public areas and only 27% ban smoking in all indoor areas, including students' rooms in dormitories and in private offices. More than 40% of the respondents reported that their schools did not offer smoking cessation programs and that the demand for existing program was low. Colleges need to do more to discourage student tobacco use. Recommended actions include campus-wide no-smoking policies that apply to student residences and identification of new ways of providing smoking prevention and cessation services.  相似文献

Abstract

In 1999, the Harvard School of Public Health College Alcohol Study surveyed 734 US college administrators to learn what colleges were doing to prevent binge drinking. Respondents rated the severity of student alcohol-abuse problems and described prevention efforts and institutional investments in prevention infrastructure. Prevention practices were widespread in the areas of general education about alcohol, use of policy controls to limit access to alcohol, restricting advertising at home-game sporting events, and allocation of living space to alcohol-free dormitories. Programming was less prevalent for more targeted alcohol education, outreach, and restrictions on alcohol advertising in campus media. Nationally, most of the surveyed colleges reported having a campus alcohol specialist, many had task forces, and about half were performing in-house data collection. Less common were program evaluations, community agreements, or neighborhood exchanges. Prevention practices varied with institutional characteristics and the surveyed administrators' perceptions of the severity of alcohol problems.  相似文献

The stated aim of this discussion is to examine the extent of male use of family planning and the nature of men's role in family planning in developing countries. Case studies are presented which are successful examples of strategies for involving men in family planning. Policies that aim to increase male involvement must be sensitive to cultural values, apply to a decentralized government approach toward information and supplies, include adequate political will, and consider the costs and benefits of changing values. A male family planning policy would not always be compatible with all fertility values in developing countries or traditional values of the older population. A policy should stress the value of male individuals contributing as much as possible for their own and others' welfare. Community participation is considered important in order to create a feeling of mutual support. A sizeable investment will be required for mass distribution of contraceptive information. Schools are viewed as an ideal place for educating youth about the problems of high fertility and about use of family planning methods, such as the condom. Religious organizations should be used to educate people about responsible parenthood and to minimize barriers to use of modern contraception. Comic books on how to use condoms are suggested as a good source. Local authorities who are trusted are useful in influencing acceptance among local populations. Local personnel may be trained as information disseminators. Adequate contraceptive information needs to be supplied to a wide audience. Lack of supply and inadequate information are given as two key reasons for insufficient use of male contraception. Condoms should be priced to be affordable to the average person and free to those with no income. Program strategies that proved successful are cited for Thailand's Mechai Viravaidya program and Bali's grass-roots program. The vasectomy program in Bangladesh is also noted for its success. Low levels of condom use are attributed to factors such as price, education, availability, accessibility, culture, religion, and economic conditions. Male sterilization levels can be enhanced with wider availability of clinics and provision of correct information for challenging beliefs that vasectomy is a form of castration.  相似文献

This qualitative study reports on thirteen assisted living (AL) administrators' perspectives of the role and the importance of the AL social worker in addressing the unmet needs of older adults as they move and transition into AL. Participant interviews were analyzed using the constant comparative method. Administrators described 5 AL social work roles: (a) decision-making and adjustment coordinator; (b) resident advocate; (c) mental health assessor and counselor; (d) family social worker; and (e) care planner. Implications include directly examining AL social workers' views, analyzing costs and benefits of employing AL social workers, and developing social work practicum sites within AL.  相似文献
