AbstractObjective: To investigate the relationships between adverse childhood experiences (ACEs), post-traumatic stress disorder symptoms (PTSD-S), and self-reported stress among college students. Participants: A total of 236 undergraduate students enrolled in nursing courses participated. Method: Using a correlational design, participants completed questionnaires online. To examine PTSD moderation between ACE and self-reported stress, multiple regression was employed. Stress outcomes were examined using a 4-group variable. Mean differences in stress response between these four groups were examined. Differences in ACE, PTSD-S, and stress response between traditional and nontraditional students were also examined. Results: PTSD-S moderated the relationship between ACEs, and self-reported stress. This indicates that students who report PTSD-S following childhood adversity perceive higher levels of stress. Nontraditional and traditional students differed in their responses to the ICLRE scale. Conclusion: Individuals who report PTSD-S following childhood adversity perceive higher levels of stress later in life. Stress reduction programs may be beneficial for students. 相似文献

AbstractObjective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N?=?854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups. 相似文献

Autocratic leaders and authoritarian followers revisited: A review and agenda for the future 总被引:1,自引:1,他引:0
P.D. Harms Dustin Wood Karen Landay Paul B. Lester Gretchen Vogelgesang Lester 《The Leadership Quarterly》2018,29(1):105-122
Despite a long history within the field of leadership, the subject of authoritarianism and how it influences leadership and leadership processes has been neglected in recent decades. However, recent global events make it clear that a better understanding of authoritarianism is needed and that leadership researchers would benefit from a renewed interest in studying why followers embrace autocratic leaders. The nature of authoritarian character, how authoritarian values develop, and how it is measured will be discussed. We will also review autocratic leadership, the factors that make it more likely, its consequences for followers, and the moderators of its effects. A future research agenda for the study of authoritarian character and autocratic leadership will be provided. 相似文献

A Comparison of Methods for Estimating the Benchmark Dose Based on Overdispersed Data from Developmental Toxicity Studies 总被引:2,自引:0,他引:2
Developmental anomalies resulting from prenatal toxicity can be manifested in terms of both malformations among surviving offspring and prenatal death. Although these two endpoints have traditionally been analyzed separately in the assessment of risk, multivariate methods of risk characterization have recently been proposed. We examined this and other issues in developmental toxicity risk assessment by evaluating the accuracy and precision of estimates of the effective dose ( ED 05 ) and the benchmark dose ( BMD 05 ) using computer simulation. Our results indicated that different variance structures (Dirichlet-trinomial and generalized linear model) used to characterize overdispersion yielded comparable results when fitting joint dose response models based on generalized estimating equations. (The choice of variance structure in separate modeling was also not critical.) However, using the Rao-Scott transformation to eliminate overdispersion tended to produce estimates of the ED 05 with reduced bias and mean squared error. Because joint modeling ensures that the ED 05 for overall toxicity (based on both malformations and prenatal death) is always less than the ED 05 for either malformations or prenatal death, joint modeling is preferred to separate modeling for risk assessment purposes. 相似文献

This study compares attitudes toward business legitimacy in three countries. Positive attitudes toward business legitimacy
exist when there is a congruence between organizational activities and societal expectations. Businesses are concerned about
the extent to which negative attitudes toward business legitimacy will lead to increased government regulation. The results
suggest that business students in all three countries are similar in their attitudes toward business legitimacy; however,
blacks have more negative attitudes toward business legitimacy than do whites. This study resulted in the validation of a
scale that can be used to measure attitudes toward business legitimacy on a cross-cultural basis. Business legitimacy is a
major concern in South Africa as the predominately white business community seeks to give the emerging black majority a stake
in the existing economic system.

Compliance Strategies and Regulatory Effectiveness of Performance-Based Regulation of Chemical Accident Risks 总被引:2,自引:0,他引:2
This paper investigates the role that performance-based regulations can play in linking a firm's environmental, health, and safety concerns with their corporate strategy. The specific focus is on the performance standards required by the Clean Air Act Amendments (CAAA) which require firms that store or use certain chemicals to develop a Risk Management Plan (RMP) for reducing the likelihood and impact of accidents at their plants. Data from a series of case studies and interviews of executives in chemical firms reveal that proactive companies integrated many of the requirements of the CAAA into their management systems prior to the regulatory requirements. Most of these firms tend to be large ones. Small firms often lack the resources to implement these regulations and hence have tended to have a more difficult time with compliance. 相似文献
