Abstract

In a questionnaire survey of New England college students, a large number of undergraduate men and women reported problems related to their personal, social, or academic adjustment. Given a list of 22 items described as “common concerns or feelings experienced by college students,” respondents were asked to rate the extent to which each item had been a problem for them in the past year. Most students (86%) reported having very much or somewhat of a problem with one or more items on the list. Pressure to do well in school, problems with weight control, anxiety, poor concentration and depression were among the most commonly reported concerns. The prevalence of these self-reported concerns and problems was found to be significantly associated with the respondents' sex, their perceptions of their health status, and academic standing.  相似文献

An alternative approach to traditionalad hoc methods of determining social worker positions is presented. It is based upon the collection of objective data and their inclusion in a mathematical formula. This apprach assures the employment of identical criteria and administrative procedures for the assignment of social workers' positions. It guarantees that for a given number of social work bureaux the assignment is equitable. The particular example presented is that of regional councils in Israel. The formula includes the variables: number of residents within each council's jurisdiction, and of community distress and distance travelled by social workers between the settlements of a council.  相似文献

The external environment of a corporation is one of the major determinants of its strategy. While this view is readily accepted, the tools to monitor this important determinant are still relatively underdeveloped. The authors have developed a managerial process which fills this gap by enabling an organization to assess its external environment effectively and economically. The approach helps executives identify major forces for strategic change in the market and non-market dimensions of the environment. The relevance of these changes is determined by measuring their impact on the mission and the strategies of the company. The process, furthermore, provides a starting point for assessing an organization's capabilities to respond to these forces for change.  相似文献

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation.  相似文献

Summary.  Many pesticide sprays that are used for crop protection are harmful to honey-bees. It can therefore be beneficial to add to the spray chemical compounds that are repellent to bees, to discourage them from feeding on recently sprayed crops. Experiments were conducted using an artificial feeding station to assess the repellent effects of various compounds. In this system, bees arrive at the feeding station, choose between feeding dishes to which different chemicals have been added, feed for a variable period and then depart. The number of bees at each feeding dish is recorded at intervals of 1 min. We discuss the analysis of data from this type of experiment, based on a queuing theory model.  相似文献

Energy policy analysis and energy modelling as applied in the case of Greece are reviewed. A complex of energy policy models in synergy is presented. These models have been developed by the Energy Policy Unit of the National Technical University of Athens and constitute the framework for analysing specific medium- and long-term policy options. A case study involving the use of new energy technologies is described. Scenarios relating to the penetration rate of new energy technologies are analysed and respective policy implications are discussed. A general conclusion to the research conducted is that with parallel work on both the content of specific policy issues and the policymaking process in general, substantial progress could be made in improving the decision-making potential of public policy organizations.  相似文献

In analyzing the impact of unions on employment stability, we introduce two innovations to correct for previous overestimates of the union effect: (1) a different approach to measure employment stability (although we use traditional measures for comparisons) and (2) panel data to obtain estimates uncontaminated by unmeasurable person differences between union and nonunion workers. Using common cross-sectional techniques, the new measures of employment stability indicate that unions account for 15 to 20 percent of employment stability variance rather than the 40 to 60 percent indicated in previous findings. Using panel techniques further reduces these measured union effects to no more than 11 percent. This research emanates from an undergraduate honors thesis written by McCutcheon, under the direction of Polachek. The authors wish to thank Thomas Kniesner, H. Gregg Lewis, and W. Stanley Siebert for valuable comments; Paul Jellinek and Lynn Igoe for superb editorial assistance; and the editor and a referee of this journal for valuable comments. The research was supported by the Carolina Population Center and the NICHD. All errors are the responsibility of the authors.  相似文献

In this paper we extend the work reported in prior studies. The conclusion drawn from the aggregate of those studies was that the limitation on liability imposed by the Price–Anderson Act for a catastrophic accident at a nuclear power plant ($560 million) is comparable to de facto limitations on recovery following catastrophic events in many other industries. The analysis in those reports was at a high level of abstraction, comparing almost exclusively the potential loss from high consequence accidents with the current assets of major firms in relevant industries. We found that potential loss exceeded assets.  相似文献

Social Accounting Matrices have been used as a means of analysing national economic structure but it is argued in this paper that their usefulness could be enhanced if they were designed to include compatible sets of socio-economic indicators which might reflect physical stocks and flows rather than strictly monetary flows. This paper considers ways in which this might be accomplished, giving particular consideration to optional approaches based on economic, social and quality of life indicators. Three approaches to providing supplementary information to the conventional Social Accounting Matrix model are considered. These include the incorporation of indicators of characteristics of households, the disaggregation of data to a geographical base and use of indicators of social attitudes and expectations. Although work continues on the first two of these suggestions, certain results concerning the third are presented. A consideration is given to the use of available secondary data to meet the needs identified. It is shown, however, that such information fails to meet the objectives of the study for various reasons. It is concluded that the necessary data can only be collected by surveys. Preliminary results of a survey carried out in Hungary beginning in May 1991 by Gallup/Hungary are presented. This information reflects attitudes of the population toward changes which are taking place and would seem to provide a means of estimating perceptions of changes in expected quality of life that result from the current efforts toward economic readjustment in Hungary.  相似文献

This study examined how child protective services (CPS) systems respond to initial and subsequent reports in the context of child maltreatment rereporting and to what extent CPS system factors are associated with the risk of rereporting after controlling for abuse type and child and family factors. This study followed 67,243 families who were reported to the CPS agencies in seven counties in Florida for child abuse and neglect over a period of 5.4 years and found that 14,218 families had one or more child maltreatment rereports. Key findings include that CPS system factors were significantly different from initial report to subsequent reports. Five CPS system factors, reporting source, contact by CPS workers, investigative level at intake, postinvestigation services, and duration ofCPS involvement were significantly associated with the risk of child maltreatment rereporting. Multivariate analyses found that CPS system factors were substantially different for three categories ofrereporting, unsubstantiated rereports, substantiated rereports, and recurrence reports. Interpretations and implications for practice are discussed.  相似文献
