In a large cross-sectional sample, commercial airline pilots in the United States were asked for their perceptions of job safety hazards. Regression techniques are employed to investigate the relationship between these perceptions and both the length of tenure of pilots and their specific employer within the industry. The latter is found to have a far more significant impact on risk perception. No evidence is found for a learning curve of job risk with respect to experience. Pilots' assessments of inadequacies in training and aircraft maintenance are found to be significantly related to the financial health of their employer.The authors would like to thank the Aviation Research and Education Foundation and the Air Line Pilots Association for financial support. We are glad to acknowledge Steven Albert, Julie Libera, Janelle Muntz, and Adam Rauch for their research assistance. 相似文献

When returning home is not a viable option, adoption is the primary means by which youth in substitute care achieve permanency. Therefore, understanding the factors that impact adoption is critical to both evaluating and improving the child welfare system. Prior research has mostly studied “main effects” in regard to adoption rates and has not explored the ways in which youth and foster family variables might interact in complex ways to predict adoption. This study uses a classification tree analysis approach known as Optimal Data Analysis (ODA) to predict probability of adoption in 2003 using Adoption and Foster Care Analysis and Reporting System (AFCARS) data. 30,000 adopted youth and 30,000 non-adopted youth were randomly selected for participation in the study. Similar to previous studies, univariate analyses revealed that age, foster parent race/ethnicity, foster parent marital status, and number of previous placements all predicted probability of adoption. However, going further, several combinations of individual variables (multivariate ODA) improved prediction accuracy (e.g., age × structure of foster family × number of previous placements). Results also suggested that the impact of the state on adoption rates varied when essentially controlling for youth and family variables, supporting concerns regarding the crude use of AFCARS data when comparing states. 相似文献

This study employs the panel threshold model to reexamine the non-monotonic relationship between CEO stock-based compensation and firm earnings across various firm-size conditions. The feasibility of the model is tested using data for US non-financial firms from 1993 to 2005. Our empirical results indicate that while a positive relationship between the CEO stock-based pay and earnings is presented for small-size firms, a negative impact of CEO stock-based compensation on earnings is shown when large-size firms are concerned. Further, the longstanding puzzle of whether the CEO stock-based pay could enhance earnings among earlier studies could be satisfactorily explained by our empirical results. 相似文献

When a child is born with a disability, the caregiver's life is altered. With the numerous challenges caring for a child with disability brings, caregivers may feel devastated. These challenges often result in increased stress on the caregiver, which, in many cases, places the child at risk for maltreatment. The purpose of this study is to explore issues a caregiver faces when caring for his or her child. In this contextual analysis, seven caregivers of children with moderate-to-severe disabilities completed a questionnaire, were interviewed individually, and assisted the researcher in constructing an ecomap of their current living environment. Content from the interviews was analyzed and several themes developed from the data. Implications for clinical practice and future research ideas are discussed. 相似文献

Abstract This research evaluates the effects of the first 1976 televised presidential debate upon voters' political attitudes. Citizens' issue awareness, campaign interest, and candidate evaluation were monitored by interviews before and after the first presidential debate in September 1976. Analysis of the survey data revealed that the debate did not significantly affect the competitive advantage of either candidate, but the debate did have the effect of increasing voters' interest and knowledge of the political campaign and decreasing the voters' confidence in both political candidates. 相似文献

This multimethod study examines selected characteristics and the motivational dynamics of remunerated blood plasma donation by U . S . university students . Ten percent of students surveyed reported selling plasma . In comparison to nondonors and nonremunerated student Red Cross donors , paid student plasma donors tended to be predominantly male and from higher income families and to have higher rates of employment while in school . They also exhibited greater rates of alcohol consumption and cigarette smoking . Drawing on focus - group and individual interviews , the authors describe the student plasma donation experience , with particular emphasis on motivational dynamics . Unlike nonremunerated Red Cross donors , plasma donors do not feel a strong identification with the altruistic aspects of the blood donor role . Rather , they are motivated to continue donating in order to secure an easy source of pocket money , which they tend to spend freely , especially on social drinking in student bars . Among students willing to sell plasma more than a few times , self - deferral from long - term donation tended to result from growing concerns about the physical effects of continuing donation , increases in disposable income from other sources , or both . The article concludes with a discussion of the implications of the findings for social policy and for future research . 相似文献

The current study tested the effectiveness of using National Alcohol Screening Day (NASD) to deliver personalized feedback via mail. At-risk NASD participants were assigned to either personalized or generic feedback conditions and attended a 4-week follow-up. Results failed to find any group differences on alcohol-related variables. However, participants in the personalized group reported a reduction in the maximum number of drinks consumed on one occasion. The personalized group also had a more accurate view of the amount of alcohol their peers consumed. NASD is a vehicle to efficiently deliver feedback to individuals about their alcohol use; however, more research is needed to determine the types of feedback that would be most effective. 相似文献
