照度变化对视觉辨认的影响

前 言 近年来,关于工业企业和民用照明视觉功能的探讨逐渐多起来,这方面的研究对于制定照度标准和保护视力有着现实意义。我国过去的研究虽获得不少有益结果,但大多是在一般照明环境中、照度一般在几百勒克斯以下,以阅读视力表作为视觉功能指标。本研究是在比较严格控制的近似等效球照度的实验条件下,在1.7-2160Lux照度范围内,控制观察时间,探讨照度变化对视觉辨认的影响。此外,我们还研究了两种背景(亮和暗)对视觉辨认的影响。

Culturally grounded strategies for suicide and alcohol risk prevention delivered by rural Alaska Native communities: A dynamic wait-listed design evaluation of the Qungasvik intervention

We examined the effectiveness of the Qungasvik (Tools for Life) intervention in enhancing protective factors as a universal suicide and alcohol prevention strategy for young people ages 12−18 living in highly affected rural Alaska Native communities. Four communities were assigned to immediate intervention or to a dynamic wait list. Outcomes were analyzed for 239 young people at four time points over two years of community intervention. Outcomes assessed two ultimate variable protective factors buffering suicide and alcohol risk, and three intermediate variable protective factors at the individual, family, and community level. Dose dependent intervention effects were associated with growth in ultimate but not intermediate variables. This evaluation of the Qungasvik intervention provides support for the effectiveness of its Indigenous strategies for suicide and alcohol misuse prevention in this rural Alaska Native setting. Though findings did not provide support for a theory of change where growth in ultimate variables is occasioned through effects on intermediate variables, research designs focused on young people who enter intervention at lower levels of preexisting protection hold promise for better understanding of intervention change processes. The Qungasvik intervention is responsive to an acute public health need for effective rural Alaska Native suicide and alcohol risk prevention strategies.     

Exploring goal taxonomies using the goal-based outcome tool in children and young people's mental health settings

Formulating goals in therapy may facilitate young people and parents/carers' engagement in mental health support settings. A number of goal taxonomies have been developed, which involve organising goals set at the outset of therapy into themes. Goal taxonomies are considered useful for service planning and outcome purposes. In order to build on the knowledge about what young people choose as goals, and to best support good practice, it is important to explore the links and differences between the existing goal taxonomies. A systematic review was conducted to identify goal taxonomies based on goals set using the goal-based outcome (GBO) tool. Framework analysis was conducted to investigate the extracted goal taxonomies. Overall, four core concepts were identified: “Goals targeting specific issues, symptoms, emotions, and behaviours,” “Return and engage in activities,” “Personal growth goals” and “Interpersonal goals.” Goals regarding specific issues, personal growth and interpersonal relationships were present in most studies. Using these overarching core concepts could be useful for practitioner-level, or service-level organisation of goal data, for activities such as service planning and delivery.

概念及概念结构研究新进展

近来有关归类和概念结构的研究与理论出现了两个方面的转变。第一个方面是从概念定义属性的假设 (经典观 )到概念表征属性的观点 (概率观 ) ;第二个方面是从概念以相似性组织的观点到概念围绕理论而组织的观点。本文综合概述了基于相似性和理论驱动的归类理论。     

表面概貌对原理运用的影响的实验研究

探讨样例与作业问题的表面概貌相似性对原理运用的影响作用。实验１扩大了Ｒｏｓｓ的研究材料中样例与测题表面概貌方面的差异程度,探讨两者的表面概貌相似性对原理运用的影响。实验２探讨样例与测题在表面概貌的事件类型方面发生改变的条件下,两者的表面概貌相似性对原理运用的影响。实验３探讨在样例与测题表面概貌有两个级别差异的条件下,两者的表面概貌相似性对原理运用的影响。３个实验均采用被试内设计,要求被试学习原理及样例后完成与样例的表面概貌有不同相似关系的测题。结果表明：（１）样例与问题的表面概貌对原理运用有影响,当两者表面概貌发生较大的变化尤其是在表面概貌的事件类型方面发生变化时,其表面概貌相似性对原理运用的影响就会明显地表现出来;（２）样例与问题的表面概貌对原理运用的影响作用,受到两者对象对应性质的制约,当对象对应相似时,其表面概貌相似就会促进解答测题时运用原理,而当两者的对象对应相反时,其表面概貌相似就会对原理运用产生干扰作用。据此可以认为,样例与作业问题表面概貌的相似性,不仅会影响原理的通达,而且也会影响原理的运用。Ｒｏｓｓ关于表面概貌相似与否不影响原理运用的结论应该予以修正。

A multiplex view of leadership structure in management teams

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed.
