As with all media, the Internet structures and frames information, rewarding some information search and decision behaviors while punishing others and, thereby, strongly influences evaluation research results and possibilities. Now that the Internet is for many evaluators the information medium of choice, the impacts of the medium on evaluation deserve careful attention. The objective of this article is to lay groundwork for a theory of the impact of the Internet on evaluation and policy analysis. Questions addressed include the following: (a) What is the impact of the Internet on the evaluator's professional role, work norms, and work habits? (b) Does the use of the Internet affect who is an evaluator or the meaning of professional evaluation? and (c) How does evaluation via Internet affect the technical quality and credibility of evaluation? A key thesis is that the Internet compresses information in the sense that it is not always easy to distinguish among information resources and, especially, the authority of the information provider and the nature of the knowledge warrant. On one hand, the Internet's information compression seems to hold potential for the democratization of evaluation. On the other hand, the diminished ability to make quality distinctions about evaluation-relevant information may undercut the legitimacy of evaluation.  相似文献

This study aimed at empirically identifying groups of adolescents with distinct longitudinal trajectories of gambling involvement and validating these groups by comparing them with respect to correlates. 903 low SES boys were followed annually from age 11 to 16 years. Three groups were found: an early-onset high-level chronic group, a late-onset high-level group, and a low gambler group. The Chronic group and the Low group consistently differed on teacher-rated inhibition (i.e., anxiety) during childhood and early adolescence. They also differed on concurrent teacher and self ratings of disinhibition (i.e., impulsivity), while the Late Onset group appeared to lie in between these groups. Compared to the Low group, both high groups subsequently had elevated scores on later gambling related problems.  相似文献

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility.  相似文献

In January 2004, the National Collaboration for Youth approved a list of core competencies needed by entry-level youth development workers for effective youth development practice. This chapter provides an overview of these competencies, explaining why and how the list was created, outcomes, and recommendations for next steps.  相似文献

Recent studies point to an emerging role for the TOR (target of rapamycin) pathway in the regulation of life span. In this Perspective, we discuss the possibility that this pathway is an important modulator of nutrient-dependent changes in life span. Additionally, we discuss the interactions between the TOR and insulin-like signaling pathways as well as the key downstream processes that TOR regulates.  相似文献

扩大个人付业并利用这一生产来增加农业的产量是当前农村的一个特点。更重要的是:因为我国目前农产品生产的水平还不能完全满足居民(其中也包括农村居民)对农产品、特别是畜产品的需要。在苏共中央提交给党的二十六大的《苏联一九八一~一九八五和一九九○年以前这一时期经济和社会发展的基本方针》草案中,规定了“要在各企业、单位和机关的付业中、居民的私入付业中以及工人和职员的果园和菜园的协作社中,增加肉、奶、土豆、蔬菜和水果的生产,帮助它们买到幼畜、饲料、种籽和肥料”。  相似文献

This study assessed child behavior problems and parent-child communication behaviors during problem solving in three groups of families with adolescent children: foster families, birthfamilies with a child at risk for behavior problems, and birthfamilies with a child not at risk. Levels of positive and negative communication behaviors in the foster families were similar to those in the lower-risk families and were significantly related to foster child behavior problems.  相似文献

School-based substance use surveys are an important data source for prevention and evaluation researchers, but access to students has become progressively restricted by schools. Because almost all states and many districts conduct their own regular surveys, archived data are a potential resource for informed policy and practice decisions. In this study, substance use survey data were successfully collected from 69 of 105 targeted school districts located in 12 states. Results indicate the availability and quality of extant data currently limit their usefulness. Recommendations are made regarding how schools could be assisted to improve the value of their substance use surveys.  相似文献

1. Providing sexual health education for adolescents with mental health problems presents a difficult but important clinical task. 2. Using a group format for this task is an effective way to provide information about sexual health and promote positive coping strategies related to relationships and sexual issues. 3. Group leaders need to be aware of their own values related to sexual issues and have the ability to be frank and nonjudgmental.  相似文献

In the absence of a "gold standard," research on domestic violence relies primarily on self-report, the quality of which is known to decline as the length of the recall period increases. Eliciting valid and reliable self-report data is crucial to the development of prevention and intervention policies and services. Nevertheless, existing measures typically do not incorporate devices to facilitate respondents' recall of the lifetime experience of domestic violence. This article describes the application of the Life History Calendar (LHC) method (Freedman, Thornton, Camburn, Alwin, & Young-DeMarco, 1988) to increase a respondent's recall of domestic violence victimization over the lifecourse. The LHC method elicits memorable information of a personal nature (e.g., children's birth dates) and uses this information to facilitate the recall of less memorable events. A recent field test of this LHC measure indicates its utility in assessing domestic violence victimization, which takes place in a complex sequence of episodes and often involves multiple perpetrators over the lifecourse.  相似文献
