Individuals in high-risk occupations (e.g., military service) often report physical, psychological, and organizational problems. Although leaders can partially buffer their subordinates against these problems, the impact of established leadership skills appears limited, especially in high-risk occupations. Thus, building on recent theories of domain-specific leadership, we examined whether leadership focused on the specific domain of sleep might be negatively associated with some specific problems facing individuals in high-risk occupations, beyond their relationship with general leadership. Studying military personnel on peacekeeping and combat deployments, we predicted that “sleep leadership” would be negatively associated with sleep problems (physical), depressive symptoms (psychological), and negative climate (organizational), and that sleep would mediate the relationship between sleep leadership and the psychological and organizational problems. Results were generally supportive, contributing to theories of domain-specific leadership by showing that sleep-focused leader behaviors may go beyond general leadership behaviors, relating directly to the problems facing individuals in high-risk occupations.  相似文献

Female circumcision is still practiced in different parts of Egypt, impacting women's health and well‐being. Existing studies often portray parents' representations of the practice as positive and homogeneous, with little attention paid to the true diversity of views within a community. This study draws on social representations theory to highlight such nuances, while identifying the psychosocial factors that shape parents' decisions to circumcise or not circumcise their daughters. In‐depth interviews with 11 mothers and five fathers were conducted in rural communities in the Al Qalyoubeya and Benisweif governorates. Thematic analysis revealed the co‐existence of positive, negative and ambivalent representations of female circumcision amongst parents and within the individuals themselves. Although some parents positively represent female circumcision as ensuring the daughter's chastity, safeguarding her femininity and preserving community identity, they feel distress about its potential harms, such as pain, bleeding and terrifying experience on the daughter. Fathers further acknowledge its negative impact on marital sexual relationships. In some cases, parents challenge the ritual and refuse to circumcise their daughters. In light of a theory of change that emphasises the role of community dialogue in renegotiating health‐damaging social practices, along with evidence of diverse views amongst parents, this study argues that sensitively facilitated ‘community conversations’ might provide parents with opportunities to debate their opposing views and allow for the construction of health‐enabling social representations.

In sports where an explosion of power or strength is necessary (e.g., weight lifting, tennis), athletes often yell or grunt to increase force production. Martial artists have used a similar technique for centuries called a kiap, but scientific evidence of its effectiveness is scarce. This study examined the effect of kiaping on strength and whether expertise influenced its effectiveness. Fifty (25 novices, 25 experts) martial artists completed a handgrip strength test under no kiap and kiap conditions. Performance for all participants was significantly better with the kiap (437.1 Newtons ± 94.9) than without (408.0 Newtons ± 90.6; p < .001).  相似文献

Using a goal-setting model (Burton, Naylor, & Holliday, 2001 Burton, D., Naylor, S. and Holliday, B. 2001. “Goal-setting in sport: Investigating the goal effectiveness paradox”. In Handbook of research on sport psychology , 2nd ed., Edited by: Singer, R., Hausenblas, H. A. and Janelle, C. M. 497528. New York: Wiley.  [Google Scholar]), the purpose of this study was to examine the effects of a goal-setting intervention upon performance as a function of skill level. A multiple-baseline across-individuals single subject design was employed with 3 elite and 3 nonelite male boxers aged between 15–17 years (M = 16; SD = 1). Self-generated performance behaviors, competition outcome, competitive anxiety intensity and direction, and self-confidence were measured across a competitive season (10-fight period). Retention was also examined following treatment withdrawal (2-fight period). During and after the goal program was completed, the elite participants displayed consistent improvements in targeted behaviors, more facilitative interpretations of anxiety symptoms, and greater self-confidence, whereas the nonelite revealed inconsistent patterns. Postintervention, five out of the six boxers showed improvement in the percentage of fights won. The results highlight the diverse effects of goal-setting for different populations, with social validation data suggesting potential mechanism via the goal-setting model employed and changes to attentional focus.  相似文献

ABSTRACT

One way to ensure that an evaluation has “utility” is to use a participatory evaluation approach where the evaluator partners with primary users to carry out various phases of an evaluation. This article provides a case study of how participatory evaluation was used in an out-of-school youth development and employment program at the Science Museum of Minnesota's Kitty Andersen Youth Science Center. Youth staff participated in a series of evaluation workshops where they learned about evaluation, made their own meaning of evaluation data, generated recommendations to improve their museum work, and ultimately took more ownership and control of their program. As a result of the workshops, youth also carried out their own formative evaluation of four museum programs. The program manager and the youth staff reaped a number of benefits from this process. The factors leading to its success are discussed.  相似文献

For decades, applied research in the field of behavioral criminology has been successfully utilized to develop theories and training modalities for the purpose of informing practice. One method for conducting this type of research is in-depth interviews of perpetrators. The Perpetrator-Motive Research Design (PMRD) is a 12-step methodological design, which focuses on gaining a thorough understanding of the motivations, values, needs, and tactics of those who commit offenses against others. PMRD has been employed in a pilot study conducted with captive-takers in the FBI's Global Hostage-Taking Research and Analysis Project (GHosT-RAP). Even though global captive-taking is a major domestic and international security problem that affects the interests of the United States, and poses serious challenges abroad, only a modicum of investigative attention has been directed to this problem. This void is addressed through the tripartite mission of GHosT-RAP: (1) to elicit and describe captive-taker values and paradigms, (2) to determine motivations and methods for captive-taking, and (3) to utilize resultant data to improve strategies for mitigation and prevention, preparedness, response, and recovery activities. In addition, GHosT-RAP will serve to formalize and operationalize the PMRD approach into a well-defined, systematic, and replicable process that can be used to better understand a myriad of offenders and their nominal enterprises.  相似文献

Perceptions of family acceptance concerning interracial friendships and romantic relationships were investigated in a group of 142 undergraduates. The Assessment Scale of Interracial Relationships (ASIR) was constructed by the authors and administered to 68 men and 74 women recruited from introductory psychology courses. Results showed that both men and women held negative attitudes toward interracial relationships, although Black students held more favorable attitudes than did White students. These findings also showed that the women were less accepting of interracial friendships and romantic relationships than the men were. Both Black and White students indicated that family perception of these interracial relationships would be negative.  相似文献

Presentation of maternal stimuli to an isolated rat pup results in what has been called “comfort” responses, as indicated by both behavioral and physiological quieting. This experiment investigated the role of passive maternal stimuli on tonic immobility and dorsal immobility in 9- and 15-day-old rat pups. Although these stimuli appeared ineffective in inducing tonic immobility, presentation of the mother did produce an increase in duration of dorsal immobility in 15-day-old pups. This increase in the dorsal immobility response may reduce struggling in the presence of the mother and thereby aid the mother in transporting the infant back to the nest.  相似文献
