专利权人引用网络中的媒介角色研究

对专利权人引用网络中的3种类型的媒介角色的概念、算法等进行梳理,根据媒介角色理论和知识交流理论对媒介角色是否影响专利权人技术创新能力做理论推导,并提出3个假设。通过实证分析发现,不同的角色影响程度各不相同:中介中心性对专利权人技术创新能力的影响力最大;5种桥系数小于中介中心性,影响最小的是结构洞约束。     

在中国大学生样本中的修订成人依恋量表 AAS

Decomposing trait and state variability in general and specific subjective task value beliefs

Expectancy-value researchers have theorized about the extent to which subjective task value components are more trait-like or more state-like. Using a bifactor representation of subjective task value data, the current study aimed to examine the degree of trait-state variation in general subjective task value, specific attainment value, specific intrinsic value, and specific utility value. The relations of both between and within components of the subjective task value constructs with academic self-efficacy beliefs were also examined. Results indicate that, in an undergraduate life science learning context (n = 169), the general subjective task value factor was the most trait-like of the subjective task value constructs. With respect to specific value beliefs, attainment value was composed of nearly equal amounts of trait and state variation, intrinsic value was composed of the largest amount of trait variation, and utility value exhibited the most state-like variation. Additionally, findings suggest that trait-like and state-like general subjective task value, trait-like specific intrinsic value, and state-like attainment value were positively associated with self-efficacy. Finally, we propose a model of trait- state dynamics in subjective task value.     

Validation of the elementary social behaviour assessment: teacher ratings of students’ social skills adapted to Norwegian,grades 1–6

This study investigated the psychometric properties of the Elementary Social Behaviour Assessment (ESBA), a teacher-report measure of students’ social skills and academic engagement adapted for use in Norwegian schools. At two times, 8 weeks apart, 151 teachers rated 793 students in Grades 1–6 on the ESBA and the Social Skills Rating System Teacher’s form (SSRS-T). Exploratory factor analysis with the first assessment suggested one or possibly two factors. Confirmatory factor analysis with the second assessment confirmed the one- or two-factor models but did not offer strong evidence for one over the other. The ESBA demonstrated good to excellent reliability. Strong concurrent and predictive correlations with the SSRS-T established criterion validity. The school and teacher levels explained only a limited amount of the total variance in ESBA scores, suggesting that teachers rate students quite similarly. The Norwegian-adapted ESBA paralleled the reliability and validity evidence from US samples.     

中国碳排放强度影响因素的动态效应分析

近年来国内外对碳排放与碳排放强度的因素分解研究,大部分集中在影响因素个体的贡献程度上,而对于影响因素的稳定性及其对碳排放或碳排放强度变化的动态冲击效应方面,缺乏相应的深入研究。本文采用Kaya恒等式的改进模型,对碳排放强度进行因素分解,得到碳排放因子、能源强度、能源结构与产业结构四个影响因素。以1980年-2009年国内的各项相关数据为基础数据,对能源强度、能源结构与产业结构与碳排放强度的相关性进行平稳性检验,并对碳排放强度与能源强度、能源结构、产业结构进行整体协整检验,检验通过后运用脉冲响应函数分析三种影像因素的变化对碳排放强度的冲击效应;利用SVAR模型中的方差分解功能,计算三种影响因素对碳排放强度的贡献度,结果显示能源结构对碳排放强度的冲击效应最弱,能源强度稍强,第三产业比重效果最为显著。     

基于科研人员需求的文献检索质量量表构建

文献检索质量是科研工作者和图书馆员共同关注的重要问题,但至今未见其简便易行的理想评价方法。在全面性、系统性、准确性、一致性、简明性、可操作性、可控性和目标性原则基础上构建文献检索质量评价量表并进行信度和效度分析检验,结果显示:量表信度指数Cronbach’sα系数为0.925;文献检索知识评价、文献检索过程评价、文献检索结果评价、信息利用程度等准则层Cronbach’sα分别为0.751、0.814、0.840和0.830,综合评分与准则层相关系数为0.5~0.9;通过因子分析确定因子载荷大于0.5的28个指标,累计方差贡献率达到了71.06%,通过信度、效度检验。该指标体系通过相关检验并得到优化,为科研中评价文献信息检索分析提供依据。

The development of a perceived masculinity scale

This essay posits that masculinity can be usefully understood from a communication perspective, and it specifically defines masculinity as a social and symbolic construct. In this view, the meanings and associations attributed to masculinity are a product of the enduring images and characteristics people have ascribed and assigned to men in groups over time. Based upon a survey of contemporary published research regarding masculinity, it is concluded that masculinity is now a multidimensional construct which attributes ten traits to people viewed as masculine which are examined in terms of: (1) physiological energy; (2) physical characteristics; (3) gender‐related sociocultural roles; (4) idealized gender; (5) gender preferences; (6) subjective gender‐identity; (7) gender‐related age identity; (8) gender‐related racial and national identities; (9) lust; and, (10) male eroticism. Specific questionnaires used to measure these dimensions are reviewed, and based on the responses of 562 subjects, the reliability and validity of one of these questionnaires is examined in detail. The essay concludes by recommending the use of the Perceived Masculinity Questionnaire 47, and it outlines some of the uses that can be made of a Perceived Masculinity Scale, especially some potential classroom uses.
