This article describes low-cost and tested procedures which may be used by the social work pracritioner-researcher for collection of data about what takes place in groups in natural setting. Some technical issues in uses of tapes of group sessions obtained by portable cassette recorders are explored. Content analysis as a research technique is explained and illustrations provided. Process analysis through measurement of such dimensions as frequency and initiator of speech is described. 相似文献

Economic analysis of life-saving investments in both the public and private sectors has the potential to dramatically improve longevity and the quality of life, but only if the analyses on which decisions are based are done well. In this article, we analyze a data set that provides information on the content and quality of journal articles that measure the cost-effectiveness of life-saving investments. Our study is the first to provide a detailed multivariate analysis of factors affecting objective measures of quality. We also explore whether a series of recommendations by an expert panel convened by the U.S. Public Health Service affect the way analyses of specific life-saving investments are done. Our results suggest that four factors are positively correlated with an index we construct to measure analytical quality: (1) having at least one author affiliated with a university, (2) publication in a journal that has experience in publishing these analyses, (3) if the life-saving investment is located in the United States, and (4) if the analysis considers a measure of social costs or benefits. Somewhat surprisingly, a study's funding source and whether it is affiliated with industry are not significantly correlated with the quality index. Finally, neither time nor the panel guidelines had an impact on the index. 相似文献

In this paper we present a two-period model in which we examine how concern about fairness might affect voter behavior. We
show that in the first period politicians choose the median voter’s position even if this does not correspond to their bliss
points and neither they nor the voters can commit to a particular action. Moreover, concern about fairness creates substantial
incumbency advantages. Our results hold even if voters care very little about fairness. 相似文献

Tax schemes are more restricted by constitutional rules than subsidies. We introduce a model of public good provision with incentive problems in agenda-setting and identify several advantages of restrictions on tax schemes. In particular, tax rules may prevent the proposal and adoption of inefficient projects that benefit only a small minority. We also propose “redistribution efficiency” as a socially desirable property of proposals and find that tax rules guarantee this kind of efficiency. Moreover, a constitution that requires certain restrictions on both taxes and subsidies satisfies a criterion we label “robustness against counter-proposals.” We provide an axiomatic characterization of this constitution. Finally, we perform utilitarian welfare comparisons. 相似文献

ABSTRACTObjectives: (1) Compare social norms and perceived peer use between college student cigarette, e-cigarette, and/or hookah users and nonusers; and (2) determine variables associated with social influences. Participants: Undergraduate students attending a large university in the Southeast United States (N = 511). Methods: An April 2013 online survey assessed use of 3 types of tobacco, social norms, perception of peer use, number of smokers in life, exposure to secondhand smoke, and demographic characteristics. Results: Participants indicated greater acceptance of emerging tobacco products than for cigarettes and consistently overestimated the percent of peers who use various tobacco products. Males and current users had higher social norm scores for all 3 forms of tobacco. Conclusion: To counter marketing of alternative tobacco products, education about the dangers of their use needs to be implemented across college campuses as part of a comprehensive tobacco control strategy that also includes tobacco-free campus policies. 相似文献

AbstractObjective: This study examined negative control (ie, perceived lack of control over life outcomes) and need for control as predictors of alcohol-problem recognition, evaluations (good/bad), and expectancies (likely/unlikely) among college students. The study also explored the interaction between the need for control and alcohol consumption in alcohol-related outcomes. Participants: Participants were a convenience sample of 500 college students from a rural Midwest university. Data were collected during the 2009–2010 academic year. Methods: Participants completed a survey assessing control and alcohol-problem recognit-ion, evaluations, and expectancies. Results: Negative control demonstrated a significant positive association with alcohol-problem recognition, evaluations, and expectancies after controlling for gender and alcohol consumption. Need for control did not have a main effect. However, the interaction was significant in that the association between need for control and negative evaluation of alcohol problems was strongest among participants with the highest levels of alcohol consumption. Conclusions: These results demonstrate that individuals' differences in sense of control are associated with alcohol-problem recognition, evaluations, and expectancies in young adults. 相似文献

The sustainability challenges society faces call for firms to manage their use of natural resources wisely. Prior work on firm responses to sustainability challenges has largely focused on explaining and enhancing economic rather than environmental performance. We build on recent developments to extend resource dependence theory to include natural resources and seek to explain how business- and environment-related firm activities influence the use of natural resources. Using a configurational approach, we develop a conceptual model that explains the return on natural resources of firms based on four distinct sets of business- and environment-related comparative advantages. An illustrative application to the car-manufacturing sector demonstrates the practical applicability of our model and provides first insights into configurations we are likely to observe in practice. Our model and its application show that economic success is neither necessary nor sufficient to enhance a firm's return on natural resources. 相似文献

The effects of a school and home-based drug prevention program on risk factors for subsequent alcohol, tobacco, and other drug (ATOD) use among children were studied. Data on parent and child risk factors for ATOD use were collected from fifty-six low-income parents and their children, ages four to six years, using a pretest-posttest design. The parent-child intervention was conducted over a two-month period. The intervention had no effect on parent or child risk factors. However, the program was favorably received by parents and children. Almost two-thirds of the parents at the experimental school were involved in the program. Almost half of the parents had high depressive symptoms. The high rates of ATOD use and depressive symptoms among these parents are cause for concern. 相似文献
