There is an increased awareness that the performance of boards (good governance) is not only determined by structural determinants but by behavioral determinants as well. These behavioral determinants might be particularly important for public and nonprofit governance, where the role of the board is more diffuse and heterogeneous than in corporate governance. Here we investigate how social dynamics within boards in secondary education influence their performance. We follow a concise model that includes cognitive conflict, the use of expertise, effort norms, and social cohesion as determinants of board task performance. A survey among all secondary schools in the Netherlands serves as the empirical underpinning for this process‐oriented model of good governance. We show that the behavioral determinants have different effects on the control task and advice task of boards. Also, we find that cognitive conflicts in supervisory boards do not lead to less but rather to more social cohesion within boards. Building on these findings, we suggest a revised model of the behavioral determinants of nonprofit board performance.  相似文献

Drawing from the theory of policy voting, this study examines the impact of opinions about gay rights on voting for presidential candidates. Qualitative analysis of the major party platforms and candidate campaign rhetoric from the six presidential elections held between 1988 and 2008 indicates that Democratic and Republican presidential candidates began openly expressing opposing positions on gay rights issues in 1992. Quantitative analysis of public opinion shows that, starting in 1992 and continuing through 2008, gay rights issues became more salient to the public, and opinions about gay rights began to exert a significant effect on vote choice. The study concludes with a discussion of the partisan forces that shaped the electoral significance of gay rights issues during the period from 1988 to 2008 and speculation about the role of gay rights issues in shaping future partisan electoral strategy.  相似文献

Objectives: We examined the social, relational and network determinants of condom use and HIV testing among men who have sex with men (MSM) in Beirut. Methods: Two-hundred thirteen men were recruited via respondent driven sampling and administered a survey. Results: Sixty-four percent reported unprotected anal intercourse (UAI), including 23% who had UAI with unknown HIV status partners (UAIU); 62% of participants had tested for HIV. In multivariate analysis, being in a relationship was associated with UAI and HIV testing; lower condom self-efficacy was associated with UAIU and HIV testing; gay discrimination was associated with UAIU; MSM disclosure was associated with UAI, UAIU and HIV testing; and network centralization was associated with HIV testing. Conclusions: Multi-level social factors influence sexual health in MSM.  相似文献

微博网络中的信息传播模型是分析用户行为,找出传播路径,确定领袖人物,发现舆情热点等研究的基础。虽然多种不同角度的信息传播模型已经得到广泛研究,但缺乏对信息动态传播过程的直观描述。本文基于Petri网的结构和特征,针对微博网络信息传播过程,提出了一种简单直观的描述模型,该模型首先对微博网络的信息动态传播过程中的对象进行结构化描述。本文根据微博网络的用户结构关系,并利用Petri网的相关理论,形式化解释和定义信息传播基本对象,从而更加直接描述了微博网络中的转发、评论、回复等多种用户行为。在此基础上,本文利用Petri网能够描述信息流动问题的特征,结合颜色Petri网和时延Petri网,从Petri网系统的角度表示信息动态传播路径,并研究网络的动态性质和传播条件,使得信息传播模型更加真实地模拟信息传播情况。最后本文分析信息传播算例和新浪微博真实数据实验,验证了模型的有效性和可行性,为舆情态势分析以及用户行为的研究提供帮助和支持,同时也为其它社交网络信息传播的用户行为描述提供了新的思路。  相似文献

文化软实力是一个国家除军事经济之外让别人主动接近的吸引力,城市公共艺术也是一种与大众有亲缘关系的艺术形态。某种程度上说,城市公共艺术是文化软实力在艺术领域的一种显象。广州城市公共艺术在器物层、行为层、制度层诠释了文化软实力的静态和动态的维度。  相似文献

We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments – information, 20% price reduction, and a moral appeal – are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption.  相似文献

电子商务市场蓬勃发展的同时,也存在严重的信息不对称现象,给消费者带来极大的购物风险。文章基于信息不对称理论,利用淘宝网交易数据对 C2C 市场上消费者的从众决策行为进行研究。研究发现 C2C 市场上店铺的日销量在店铺间存在二八分布的特征,说明网络消费者在购买商品时有从众行为。基于面板模型对店铺市场份额的研究表明,店铺历史销量信息对消费者选择店铺的决策有显著正向影响,而店铺信用对消费者决策的影响并不显著。因此,建议 C2C 交易平台增加退货量指标、动态销量图以及销量和价格的相互对应信息等,以促进消费者理性购物。  相似文献

Individuals differ in their sensitivity toward injustice. Justice‐sensitive persons perceive injustice more frequently and show stronger responses to it. Justice sensitivity has been studied predominantly in adults; little is known about its development in childhood and adolescence and its connection to prosocial behavior and emotional and behavioral problems. This study evaluates a version of the justice sensitivity inventory for children and adolescents (JSI‐CA5) in 1472 9‐ to 17‐year olds. Items and scales showed good psychometric properties and correlations with prosocial behavior and conduct problems similar to findings in adults, supporting the reliability and validity of the scale. We found individual differences in justice sensitivity as a function of age and gender. Furthermore, justice sensitivity predicted emotional and behavioral problems in children and adolescents over a 1‐ to 2‐year period. Justice sensitivity perspectives can therefore be considered as risk and/or protective factors for mental health in childhood and adolescence.  相似文献

This study investigated developmental trajectories for prosocial behavior for a sample followed from the age of 10–18 and examined possible adjustment outcomes associated with membership in different trajectory groups. Participants were 136 boys and 148 girls, their teachers, and their parents (19.4 percent African‐American, 2.4 percent Asian, 51.9 percent Caucasian, 19.5 percent Hispanic, and 5.8 percent other). Teachers rated children's prosocial behavior yearly in grades 4–12. At the end of the 12th grade year, teachers, parents, and participants reported externalizing behaviors and participants reported internalizing symptoms, narcissism, and features of borderline personality disorder. Results suggested that prosocial behavior remained stable from middle childhood through late adolescence. Group‐based mixture modeling revealed three prosocial trajectory groups: low (18.7 percent), medium (52.8 percent), and high (29.6 percent). Membership in the high prosocial trajectory group predicted lower levels of externalizing behavior as compared with the low prosocial trajectory group, and for girls, lower levels of internalizing symptoms. Membership in the medium prosocial trajectory group also predicted being lower on externalizing behaviors. Membership in the high prosocial trajectory group predicted lower levels of borderline personality features for girls only.  相似文献
