This study investigates the predictive ability of Leadership Developmental Levels (Constructive/Developmental Theory) in a model of leader performance. Using 67 executive leaders from a Leadership Development Consulting firm, Leadership Developmental Level was found to predict leader performance for males, but not for females. This study investigates potential sources of this discrepancy, including rater bias, Performance Differences, Developmental Differences, Interpersonal Connection Style, and Gender Moderation. It is found that the source of the gender distinction is in Interpersonal Connection Style.  相似文献

The study aimed to assess the prevalence of cannabis and amphetamine use and socio-ecological proximal and distal factors among adolescents in six Pacific Island countries. We analyzed cross-sectional survey data from 9,849 adolescents (mean age 14.2 years, SD?=?1.2) from Cook Islands, Kiribati, Samoa, Solomon Islands, Tonga and Tuvalu that participated in the “Global School-Based Student Health Survey (GSHS)” in 2011–2013. The prevalence of past-month cannabis use was 15.5%, and lifetime amphetamine use was 14.5%, with the highest prevalence in Samoa, 37.1% and 34.6%, respectively. In adjusted mixed-effects logistic regression analysis male gender, personal attributes (anxiety, loneliness, current tobacco use, current alcohol use and school truancy) and environmental stressors (having been in a physical fight, been physically attacked, sustained an injury, hunger and being bullied) were associated with past-month cannabis and/or lifetime amphetamine use. Parental substance use was positively and parental involvement negatively associated with past-month cannabis and/or lifetime amphetamine use. Measures to prevent and control cannabis and amphetamine use in this adolescent population should include personal attributes, environmental stressors and parental support.  相似文献

The emotional victim effect (EVE, i.e., that the emotionality of a victim's demeanor affects perceived credibility) is a robust research finding for female victims of rape but much less explored for other types of victims and crimes. In this article, we investigate the EVE with a male assault complainant. In addition, we vary the presentation mode via which the complainant is shown to the assessors. A sample of law students (N = 81) participated in an experiment where they viewed and assessed credibility of a male complainant who appeared either live or on video. The complainant behaved either in an emotional or a neutral manner. Result showed that the presentation mode but not the EVE affected the assessors' credibility assessments: The complainant was perceived as more truthful when communicating live, as opposed to via video. Practical implications, as well as the generality of the EVE, are discussed.  相似文献
