Models of prototyped and non-prototyped competitions for prime contracts from the U.S. defense department suggest that the latter are much more vulnerable to bid-rigging than are the former. Subcontracting data reveal that pairs of firms who have been rivals in major non-prototyped competitions have a larger number of subcontracts with one another than do other pairs of firms. The analysis concludes that subcontracts may serve as vehicles for division of the spoils of collusive bidding on prime contracts.  相似文献

This article examines the selection and use of a budget approval technique. Specifically, two research questions are addressed: (1) Does the use of a particular budget approval method by a governmental body impact the execution of the budget? (2) What characteristics of a local government are associated with its decision to use a particular budget approval method? Both research questions are addressed by analyzing data from public school systems in the Commonwealth of Virginia, specifically, whether using categorical budget approval differs in the accuracy of budgeting versus using a lump-sum approval method. Characteristics of Virginia school districts are also analyzed according to whether any of them are likely to be associated with school districts using a particular approval method. The remainder of this article is organized as follows: the next section describes the role of budgeting control in schools; subsequent sections review Virginia school district budgeting practices, develop the empirical model used to test the hypotheses, describe the sample, analyze the results of empirical tests and discuss implications of the findings.  相似文献

Based on findings from the 1970s, research literature on senior government executives emphasized a growing integration of politics and administration. This integration was reflected in what we called the "Image IV" bureaucrat wherein political role traits combined with those of traditional bureaucratic ones. Although this was by no means a dominant trend, we were led to speculate that traditional divisions between political and bureaucratic roles were eroding. Data gathered from the 1980s and 1990s, however, lead us to infer that divisions between political and bureaucratic roles have reasserted themselves and that integration between them is being diminished rather than strengthened. We conclude that this may be because in an era of governmental austerity the demand for executive policy entrepreneurs has slackened while the political needs have shifted to those of managerial control over an inertial or even contracting state.  相似文献

First- and second-year findings from a study of the development of disordered eating in pre- and early adolescents are presented. Fifth- and sixth-grade girls (n = 80) and boys (n = 85) were assessed on depression, body image, self-esteem, and eating behaviors and attitudes in Year 1 and again one year later. Weight, height, and pubertal development were also evaluated in Year 1 and Year 2. Gender differences existed on all measures in Year 2 and indicated consistently poorer scores for girls compared to boys. For girls, Year 1 Body Mass Index and pubertal development predicted Year 2 disordered eating. For boys, poor body image in Year 1 predicted Year 2 disordered eating. The importance of identifying early risk factors for eating disorders is discussed.  相似文献

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are discussed.  相似文献

The study assessed whether the impact of social support on self-esteem is moderated by the adolescent's orientation toward the source of aid. Questionnaires were administered to 84 Israeli adolescents regarding self-esteem, perceived level of support from parents and peers, and preference, or orientation, for support from these sources. Regression analyses indicated that the positive effect of social figures' support on self-esteem increased as a function of interest in receiving aid from the specific source. Correlational analyses also revealed that heightened orientation toward parents was associated with higher levels of perceived parental support, whereas heightened orientation toward peers was associated with higher levels of peer support and lower levels of parental aid. These findings were consistent with self-evaluation maintenance and social provision theories, which suggest that the individual has an active role in selectively seeking out and filtering external social influences.His doctorate in educational psychology is from UCLA. Current research interests include stress and coping across the life span, social sources of adolescent self-esteem, and intergroup relations in the junior high school.Her doctorate in clinical psychology is from the Hebrew University in Jerusalem. Her research interests include family relations, social and emotional development in children and adolescents, and developmental psychopathology.Her research interests focus on social support in the family.  相似文献

This study examines characteristics that distinguish succeeding and failing Hispanic students at an inner-city high school. While research on this topic has historically focused on dropouts, this study seeks to better understand successful high school students. Participants in the study were 48 Hispanic tenth-grade students at a large, predominantly minority and low-income high school. High-and low-risk groups were identified on the basis of ninth-grade attendance rates and course failures. When compared to their high-risk counterparts, low-risk students were found to be more satisfied with their school and to maintain a social group predominantly free of gang members. The findings are discussed in terms of how the distinguishing variables contribute to students' success.Obtained degree in clinical-community psychology from DePaul University. Research focuses on adolescent risk factors, particularly as they relate to academic success and high school completion.Earned degree in clinical-community psychology from the University of Rochester. Has published extensively on issues related to prevention and community psychology. Most recently work has focused on strategies to help high-risk school transfer children adjust to the academic demands of their new schools.  相似文献
