政府与公共图书馆——关于图书馆制度的一种规范分析

公共图书馆是一种典型的公共产品。它的高度正外部性特征,决定了市场提供的非效率性。公共图书馆只能由政府提供,政府必须履行公共图书馆投资主体的责任。为解决公共图书馆的拥挤性和地域性问题,政府必须承担普及公共图书馆的责任,并提供投资保障。图4。参考文献9。     

Strength in Numbers: Encouraging Every Staff Member to Work to Capacity

Libraries play a critical role in enhancing the learning landscape of the schools they support. In order for any library to become a powerhouse and a community meeting place, all library team members need to align with the library's vision, own it and begin to add their own strengths and talents purposefully. This article explores practical strategies for developing a visionary team, including supportive leadership, daily stand-up meetings, weekly staff meetings, special-focus teams, rostering and the “five conversations” approach. These effective strategies can be implemented across a broad range of library workforce contexts in order to ensure the most effective workforce teams are built.     

Cross-Cultural Adaptation and Psychometric Properties of the Portuguese Version of the Life Skills Scale for Sport

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.     

“But it doesn’t come naturally”: how effort expenditure shapes the benefit of growth mindset on women’s sense of intellectual belonging in computing

Research suggests growth mindset, or the belief that knowledge is acquired through effort, may enhance women’s sense of belonging in male-dominated disciplines, like computing. However, other research indicates women who spend a great deal of time and energy in technical fields experience a low sense of belonging. The current study assessed the benefits of a growth mindset on women’s (and men’s) sense of intellectual belonging in computing, accounting for the amount of time and effort dedicated to academics. We define “intellectual belonging” as the sense that one is believed to be a competent member of the community. Whereas a stronger growth mindset was associated with stronger intellectual belonging for men, a growth mindset only boosted women’s intellectual belonging when they did not work hard on academics. Our findings suggest, paradoxically, women may not benefit from a growth mindset in computing when they exert a lot of effort.     

积极心理学:理念、视野及动向

积极心理学是二十世纪末在美国兴起的新的心理学研究思潮,它关注人性中的积极层面,包括积极情绪体验、积极人格特征、积极社会环境,力图完成从消极心理学模式向积极的心理学模式转换,使被现代主流心理学所遗忘的人类的积极品质从边缘转向中心,从幕后走向前台,从而开辟了现代心理学研究新趋向、新视野和新领域,成为心理学研究中新的极具生命活力的生长点。

Examining the effect of positive behaviour support on academic achievement of students with disabilities

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.
