The field of applied behavior analysis has been directly involved in both research and applications of behavioral principles to improve the lives of captive zoo animals. Thirty years ago, Forthman and Ogden (1992) wrote one of the first papers documenting some of these efforts. Since that time, considerable work has been done using behavioral principles and procedures to guide zoo welfare efforts. The current paper reexamines and updates Forthman and Ogden's original points, with attention to the 5 categories they detailed: (a) promotion of species-typical behavior, (b) reintroduction and repatriation of endangered species, (c) animal handling, (d) pest control, and (e) animal performances. In addition, we outline 3 current and future directions for behavior analytic endeavors: (a) experimental analyses of behavior and the zoo, (b) applied behavior analysis and the zoo, and (c) single-case designs and the zoo. The goal is to provide a framework that can guide future behavioral research in zoos, as well as create applications based on these empirical evaluations.  相似文献

The associations of physical activity and sedentary behavior with barriers, enjoyment, and preferences were examined in a population-based mail survey of 1,332 adults. Respondents reporting high enjoyment and preference for physical activity were more likely to report high levels of activity. Those reporting cost, the weather, and personal barriers to physical activity were less likely to be physically active. Preference for sedentary behavior was associated with the decreased likelihood of being physically active, and the weather a barrier to physical activity was associated with the increased likelihood of sedentary behavior. These constructs can be used to examine individual and environmental influences on physical activity and sedentary behavior in specific populations and could inform the development of targeted interventions.  相似文献

Cet article examine la relation entre les styles de leadership, l’implication et la perception des cultures et subcultures organisationnelles. L’impact de la culture et du style de leadership sur l’implication a déjàété envisagé, mais on manque d’informations sur les relations que les différents types de culture et de styles de leadership entretiennent avec l’implication. L’article est centré sur la notion de subculture organisationnelle et la façon dont la perception de ces cultures rejaillit sur l’implication, la subculture étant une variable négligée dans la littérature sur l’implication. Cette question fut abordée dans une enquête portant sur 258 infirmières relevant de divers secteurs hospitaliers de l’agglomération de Sydney. Les résultats indiquent que la subculture organisationnelle perçue est forcement reliée à l’implication. On précise en outre la force du lien existant entre l’implication et les différents types de leadership et de subculture. Les subcultures innovantes et centrées sur les personnes bénéficient d’une relation nettement positive tandis que les subcultures bureaucratiques souffrent d’une relation négative. Pour ce qui est des styles de leadership, un style centré sur les relations présente un lien plus fort avec l’implication qu’un style centré sur la tâche. Une analyse de régression a permis d’étudier l’éventuel rôle médiateur de la subculture dans l’influence du leadership sur l’implication. Le leadership a des effets à la fois directs et indirects sur l’implication. On traite finalement des retombées sur la pratique et les recherches à venir. This paper investigates the relationship between perceptions of organisational culture, organisational subculture, leadership style, and commitment. The impact of culture and leadership style on commitment has been previously noted, but there is a lack of detail regarding how different types of culture and leadership styles relate to commitment. The paper particularly addresses the notion of organisational subcultures and how the perception of those cultures relates to commitment, subculture being a neglected variable in the commitment literature. These issues were addressed in a survey of 258 nurses drawn from a range of hospital settings and wards within the Sydney metropolitan region. Results indicate that perceived organisational subculture has a strong relationship with commitment. Furthermore, the results identify the relative strength of specific types of leadership style and specific types of subculture with commitment. Both innovative and supportive subcultures have a clear positive relationship, while bureaucratic subcultures have a negative relationship. In terms of leadership style, a consideration style had a stronger relationship with commitment than a structuring style. Regression analysis was used to investigate the possible role of subculture as a mediator for the influence of leadership on commitment. Both direct and indirect effects of leadership on commitment were found. Implications for practice and for further research are discussed.  相似文献

Depression in adolescent girls may result in negative consequences in young adulthood. The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to 1,727 Black and White girls ages 16 to 18 years who participated in the National Heart, Lung, and Blood Institute's Growth and Health Study. Three years later, women in the depressed groups were more likely to be current smokers, had attained a lower level of education, and reported lower self-worth relative to the nondepressed group. Body dissatisfaction, eating concerns, and loneliness were greater in the depressed groups. Relative to Black women, White women who were moderately depressed during adolescence reported more health care services utilization in young adulthood. Prevention efforts for depressed adolescents should be broadly focused to improve young adult outcomes.  相似文献

Due to logistical and financial barriers that keep many distressed couples from seeking psychotherapy, online relationship education is a more accessible alternative. In the decade since a web-based program showed equivalent effectiveness to traditional marriage education (Duncan et al., 2009), several fully online programs have been developed and evaluated. We reviewed nine studies of four different programs that sampled 2,000?+?couples. Specifically, we rated each study’s experimental rigor and compared research designs, theoretical and empirical grounding, average post-intervention and follow-up effect sizes, and differential effectiveness. Across studies, measured outcomes included relational (improved satisfaction, quality, confidence, commitment, communication; reduced conflict and aggression) and individual functioning on various indices of mental and physical health, emotional expression, and quality of life. Finally, we discuss the strengths and limitations of the research evidence, describe the two most evidence-based programs (ePREP and OurRelationship) in some detail and make recommendations for future study of these promising kinds of interventions.
