Current records and record range with some applications

In a sequence of independent and identically distributed (iid) random variables, the upper (lower) current records and record range are studied. We derive general recurrence relations between the single and product moments for the upper and lower current records based on Weibull and positive Weibull distributions, as well as Pareto and negative Pareto distributions, respectively. Moreover, some asymptotic results for general current records are established. In addition, a recurrence relation and an explicit formula for the moments of record range based on the exponential distribution are given. Finally, numerical examples are presented to illustrate and corroborate theoretical results.

Transformational leadership climate: Performance linkages, mechanisms, and boundary conditions at the organizational level

Transformational leadership (TFL) climate describes the degree to which leaders throughout an organization engage in TFL behaviors. In this study, we investigate performance linkages, mechanisms, and boundary conditions of TFL climate at the organizational level of analysis. In a sample of 158 independent organizations, 18,094 employees provided data on TFL climate, positive affective climate, trust climate, and employees' task performance behavior and organizational citizenship behavior. In addition, human resource managers rated overall employee productivity. Study results yielded a pattern of moderated mediation for overall employee productivity and employees' aggregate task performance behavior, in that an organization's TFL climate was indirectly (through positive affective climate) related with these outcome variables under conditions of high trust climate, but not under conditions of low trust climate. Further, we found an organization's TFL climate to indirectly relate with employees' aggregate organizational citizenship behavior through positive affective climate, largely independent of the level of trust climate.

强化市场自主性增长因素的财政支出政策

市场自主性增长因素增强,但市场自主性增长机制还不完善,目前应继续实施积极财政政策。目前积极财政政策应优化财政支出结构,以承担提供农村公共产品、社会保障显性或隐性债务等任务为主,提高财政政策质量,稳定社会公众的预期,强化市场自主性增长因素,激活消费需求,实现扩大社会总需求目标。     

“Giving Voice” to Youths in Out-of-Home Placements

This article describes the impact of participating in a unique approach to positive youth development on a group of youths in out-of-home placements. The program provided young people with the opportunity to inform service providers and other adults about their experiences within the youth services system. Analyses of qualitative data identified seven arenas in which participating youths appeared to be influenced—initiation and growth, safety, connection, expression, personal impact, conflict and misbehavior, and opportunity to make a difference. Findings indicate that participants gained resiliency in the face of the adversities they had and continue to experience. Their life skills and competencies were enhanced. They developed a more positive outlook on life and a greater sense of self-efficacy and self-determination. Participation lessened their feelings of isolation, powerlessness, and apathy.
