节点对,指网络中一条联系及其两端节点的组合。作为信息网络中底层的联系组件,节点对表征最基础的信道,但却难以被直接测度。本文尝试引入删除法,构建节点对的间接测度,并给出分别测量网络整体节点数量(信息存量)和联系权重(信息流量)损失的LN和LS指数,用于挖掘无向网络中的关键节点对。h指数研究科研合作网络的实例显示,删除法挖掘出了该网络中具有组织作用、具有桥梁作用或具有相似结构对等性的各类关键节点对。基于删除法的信息网络间接测度方法,有望促成信息网络联系组件测度研究的新视域。图7。表2。参考文献26。  相似文献

阐述科研合作网络弹性的概念、研究意义与应用,并以全球100所高校在图书情报学领域所组成的科研合作网络为例,选取网络最大簇规模和网络效率作为网络弹性测度指标,讨论节点点度失效、介数失效以及随机失效策略下该科研合作网络的弹性。结果显示,科研合作网络对随机节点失效具有较强的鲁棒性,其网络容错能力较强;对选择性节点失效的网络抗攻击能力较弱;网络效率相对于网络最大簇规模更适合作为科研合作网络弹性的测度指标。  相似文献

科技领域交叉融合创新的趋势下,团队合作成为重要的知识生产形式。准确测度团队知识、刻画团队知识结构,是理解团队创新行为机制的基础,对创新团队的管理与发展具有重要意义。本文创新性地结合网络分析方法和知识嵌入视角,对传统的知识测度方法进行改进,使之更适用于科技团队知识测度。首先,使用最大连通子图从全领域合作网络中识别科技创新团队,基于直接关联与间接引用拓展团队成员的个体知识网络,继而集成得到团队加权知识网络。其次,基于网络分析的两大研究视角——位置取向与关系取向,分别构建知识重合度、知识多样性与知识凝聚性三个指标,用于测度团队知识;在指标测度中对以往方法加以改进,将团队知识嵌入全领域知识网络中计算。最后,选择生物医药领域进行实证,对团队知识测度指标及其内涵进行讨论分析。位置取向的知识重合度与知识多样性分别测度共有知识和异质知识,能够反映团队知识的组成成分;关系取向的知识凝聚性则反映团队知识之间的结构一致性和内容连贯性。多数科技创新团队中知识节点的位置分布均衡,但知识之间关系的结构差异较大。知识多样性与创新绩效呈现倒U形关系,是团队创造力尤其是突破性创新能力的重要来源;令人意外的是,知识凝聚性...  相似文献

People communicate differently based on their willingness to communicate, along with their feelings of solidarity with the receivers (McCroskey & Richmond, 1987). People who are high in their willingness to communicate and feel close to their receivers would seemingly communicate more frequently and intimately. This study investigated this proposition by considering the late adolescent sibling relationship. College students were asked to complete a questionnaire focusing on the frequency, breadth, and depth of their communication with their siblings. Participants also completed measures of their trait willingness to communicate, their willingness to communicate with their siblings, and their solidarity with their siblings. People's willingness to communicate and willingness to communicate with their siblings was positively related to their frequency, breadth, and depth of communication with their siblings. Solidarity was also found to be positively related to frequency, breadth, and depth of communication.  相似文献

Course: Small Group Communication

The purpose of this assessment was to examine whether differences exist between students who self-select their classroom work group members and students who are randomly assigned to their classroom work groups in terms of their use of organizational citizenship behaviors with their work group members; their commitment to, trust in, and relational satisfaction with their work groups; and their self-reports of affective learning and cognitive learning. Participants were 126 students enrolled in a small group communication course. While students who self-select their group members and students who are randomly assigned to their groups do not differ in their use of organizational citizenship behaviors with their classroom work group members, students who self-select their classroom work group members do report higher levels of commitment, trust, and relational satisfaction, as well as more affective learning and more cognitive learning, than students who are randomly assigned to classroom work groups.  相似文献

Students reflecting on their time as students in a school of information provide advice and commentary for their faculty. By revealing their challenges as well as their successes, educators can themselves reflect on the impact of their teaching and the potential it has to assist students on their career paths.  相似文献

A national survey of radio station general managers and news directors explored their demographic characteristics and stands on social issues. News directors’ support for a national health care program, their lack of support for unregulated business, their lack of trust in private enterprise to look out for the workers’ welfare, and their less negative view of labor unions may be explained through their own experience, as well as those of their newsroom employees.  相似文献

Family members create a social environment that varies in terms of the degree to which it evokes hurt. Two studies were conducted to examine the nature of hurtful family environments and to assess whether the association between people's experience of their family environment as hurtful and their perceptions of hurtful family interactions could be described by a sensitization or a habituation model. The results indicated that hurtful family environments are characterized by aggression, a lack of affection, neglect, and violence. Individuals’ views of their family environment as aggressive were negatively associated with their own verbal hostility and their self-esteem, but positively linked to their anxiety and to their tendency to see a family member's hurtful behavior as intentional. People's tendency to note their family displayed a lack of affection was positively linked to their own verbal hostility and negatively associated with their self-esteem. The findings also offered partial support for a habituation model: Those who said their family environment was characterized by a lack of affection rated hurtful family interactions as less emotionally painful than did others. Together, the results provide a rationale for examining the emotional contexts created by family members as well as the implications of those contexts for individuals and their family relationships.  相似文献

The attribution theory of emotion (Weiner, 1986) is presented as a common example of a naïve theory finding that people expect attributions of personal control and other control to underlie feelings of guilt and anger respectively. The study predicts that supporters use this implicit knowledge to focus their supportive messages on the attributions corresponding to their recipients’ reported emotions. It is also possible that supporters are influenced by their own attributions about support recipients’ problems. The data from 84 college students indicate that the supporters’ intended and actual messages tended to follow their own attributions about their recipients’ situation rather than the attributions implied by the emotions reported by their recipients. It is suggested that some supporters fail to be comforting to their recipients because they do not perceive the situation in the same way as their recipients, and may therefore try to change their recipients ‘ perceptions of their problems.  相似文献

An e-mail survey of online journalists reveals that online journalists' emotional responses to their competitors' coverage are significantly correlated with their job satisfaction, workload, and the perceived quality of their news website. The more negatively online journalists feel when they get scooped by their competitors, the more unsatisfied they are with their jobs. The more negatively the journalists feel about getting scooped, the more the workload the journalists feel that they have. The more positively online journalists feel when they scoop their competitors, the more positively they perceive the quality of their news website. In addition, the greater the workload the journalists consider that they have, the more unsatisfied they are with their jobs. The more positively the journalists perceive the quality of their news organization, the more satisfied they are with their jobs.  相似文献
