Workplaces are ideal contexts for mentoring relationships between adults and older youth. To teach the competencies required in contemporary workplaces (many of which are equally useful in other settings), mentors need to use sophisticated teaching behaviors, which the authors characterize as reflective questioning and problem solving. 相似文献

A number of governments and public policy institutes have developed Quality of Life Indexes – statistics that attempt to measure the quality of life for entire states or regions. We develop 14 criteria for determining the validity and usefulness of such QOL indexes to public policy. We then review 22 of the most-used QOL indexes from around the world. We conclude that many of the indexes are successful in that they are reliable, have established time series measures, and can be disaggregated to study subpopulations. However, many fall short in four areas: (1) indexes vary greatly in their coverage and definitions of domains of QOL, (2) none of the indexes distinguish among the concepts of input, throughput, and output that are used by public policy analysts, (3) they fail to show how QOL outputs are sensitive to public policy inputs, and (4) none have examined convergent validity against each other. We conclude that many of these indexes are potentially very useful for public policy and recommend research to further improve them. 相似文献

Three topics are addressed: (1) measurement issues (e.g., the reliability and validity of neurobehavioral test scores), (2) general principles of assessment, including test selection, and (3) interpretation of scores. Psychological tests generally perform as well as medical tests in terms of reliability and validity. Test manuals, assessment textbooks, and psychologists are useful resources to the risk assessor. The variety of different tests employed in neurobehavioral studies complicates interstudy comparisons. In addition, tests that ostensibly assess the same general domain of function might assess somewhat different abilities within that domain. Although a uniform battery for use in all studies seems desirable, the battery appropriate for a specific study depends on study goals, knowledge about the mechanism(s) of neurotoxicity, nature of the study population, and pattern of exposure. Exposure-related neurobehavioral deficits are generally indicators of "altered function" rather than of "clinical disease." Limiting concern to end points corresponding to clinical disease might not be appropriate. Many neurobehavioral diagnoses are phenomenological and a neurotoxicant might cause a unique pattern of deficits for which no label has been created. The concern that a small shift in the central tendency of a distribution of test scores has no significance for the individual should be reexamined in light of the prevention paradox, formulated on the basis of epidemiologic studies of chronic disease. Poor performance on a neurobehavioral test does not necessarily map clearly onto underlying behavioral or neural substrate. The absence of such linkages, given current knowledge about brain-behavior relationships, should not reduce confidence in neurobehavioral end points. Use of neurobehavioral test scores involves considerations that differ little from those that the risk assessor routinely addresses in using end points commonly used in research on other topics in environmental epidemiology. 相似文献

A central sociological problem is the extent to which genetics and the environment influence human behavior. Studies of twins are a core method in attempts to disentangle and to determine the comparative strength of genetic and environmental influences on psychosocial outcomes. A critical assumption of twin studies is that both monozygotic "identical" twins and dizygotic "fraternal" twins share common social environments. Therefore, any greater similarity of monozygotic than dizygotic twins is attributed to genetic influences. This paper tests the equal environment assumption by examining the extent to which greater concordance of adolescent monozygotic compared to dizygotic twins results from social, as well as genetic, influences. Bivariate comparisons indicate that monozygotic twins show greater similarity than dizygotic twins in socially-based characteristics including physical attractiveness, time spent in each other's company, the overlap in friendship networks, and friends' use of alcohol. Multivariate analyses indicate that measures of the social environment sometimes reduce or eliminate apparent genetic effects. In comparison with genetic indicators, social variables are usually stronger predictors of depression and alcohol use and abuse. These findings suggest that past twin studies could overstate the strength of genetic influences because some similarities in behavior among monozygotic compared to dizygotic twins stem from social influences. 相似文献

This paper examines the links between individual adolescent smoking behavior and actual and perceived smoking behavior in the individual's school cohort. We hypothesized that students enrolled in schools with higher smoking prevalence among students in their grade are more likely to smoke subsequently. We also expected perceived school-level prevalence of smoking to have a greater impact than actual prevalence because the former is a more direct measure of perceived norms. Adjusting for demographics, actual school-level prevalence at baseline (grade 7) was strongly associated with smoking frequency one year later. However, the association disappeared after adjusting for individual smoking frequency at baseline. School-level prevalence did not moderate the association between individual's baseline and subsequent smoking frequency. Perceived prevalence of smoking among grade 8 students and two measures tapping the behavior of smaller peer groups--cigarette offers and exposure to friends and other peers who smoke--were associated with increased risk of smoking. 相似文献

This article presents a consensus-building initiative to develop a statewide research agenda that responds to the needs of Illinois's child welfare community. Researchers conducted this process through a university-community partnership to engage those interested in child welfare services. The process and findings resulted in a living document that will guide child welfare research throughout the state. Findings of the inquiry suggest that the development of best practice models may be one of the most important contributions research can make to practice. 相似文献

Interest in change interventions that are common to different models of relationship therapy has spurred investigation of enactments as one such candidate. In change-focused enactments, therapists structure and coach couple/family interaction, as opposed to channeling interaction through the therapist. Still, varying levels of couple/family distress, volatility, and reactivity mean that readiness for enactment intervention varies along a broad continuum and changes over the course of therapy. This suggests the need for differentiated enactments. Currently, however, no model exists for adapting enactments to changing relationship conditions. We propose a five-stage developmental model of clinical operations in couple therapy that adapts the process and structure of enactments to changing levels of relationship distress, interactional volatility, and emotional reactivity. The model increases the possibility for therapists to use enactments successfully over the entire course of couple therapy. Issues to be considered in using the couple enactments model as a template for the development of enactment models for other relationship systems are noted. 相似文献

Childhood behavioral and emotional disorders 总被引:3,自引:0,他引:3

We reviewed the literature on family treatment for childhood behavioral and emotional disorders and found an increase in the number of studies since 1995; however there was significant variation by disorder and therapy model. There is substantially more research on externalizing disorders (i.e., conduct disorder, attention deficit hyperactivity disorder, oppositional defiant disorder) then internalizing disorders, depression and anxiety disorders. The data support the conclusion that family-based interventions produce results comparable to individually oriented interventions, and in some cases family-based interventions are superior to individual treatments. To date, cognitive behavioral family therapy and parent management have been the two models studied, almost exclusively. Implications for family therapy and future research are considered. 相似文献

To address the rise in tobacco use among college students, several national health organizations, including the American College Health Association, recommend that colleges enact smoking bans in and around all campus buildings, including student housing, and prohibit the sale, advertisement, and promotion of tobacco products on campus. Key informants at 50 US public universities, one from each state, were interviewed during the 2001/2002 academic year to assess the prevalence of these recommended policies. More than half (54%) of the colleges banned smoking in all campus buildings and student residences, 68% had no tobacco sales on campus, and 32% of the schools' newspapers did not accept tobacco advertising. Regional differences in adoption of these campus tobacco-control policies were present. Although this national sample of public universities had implemented some of the recommended policies, they must take further actions to comply fully with campus tobacco-control guidelines. 相似文献
