社交物联网是社交网络概念在物联网中整合后兴起的一个蓬勃发展的研究领域。提出了一种适用于社交物联网网络的改进型节点级信任模型,并通过与其他信任模型的对比仿真实验证明在恶意节点的攻击下,提出的模型拥有更好的稳定性和适用性,总体波动较小。同时,针对实际社交物联网网络中新加入网络的陌生节点可能遇到的网络延迟影响信任值评估的问题,在改进型节点级信任模型的基础上进一步使用了深度学习模型对其进行信任值预测。仿真证明,使用深度学习预测后模型的系统性能明显优于不使用深度学习的模型,成功交互率提升约1.8%。 相似文献

The proposition that entrepreneurs’ innovation is embedded in networking is refined. We distinguish between networking in the public sphere and networking in the private sphere, and hypothesize that innovation benefits from public sphere networking but suffers from private sphere networking. These hypotheses are tested with a representative sample of 56,611 entrepreneurs in 61 countries surveyed in the Global Entrepreneurship Monitor. Hierarchical linear modeling shows that, while overall networking benefits innovation, innovation is decreased by private sphere networking and increased by networking in the public sphere, especially in the professions and internationally. A further refinement is to consider entrepreneurs’ endeavors as embedded in society with its system of education for entrepreneurship. We hypothesize that the quality of a national system moderates the impacts of networks on innovation by adding value to networks. Analyses show that quality of national educational system adds innovation benefits to both public sphere networking and private sphere networking. 相似文献

Recent studies have called for a better understanding of the link between networking and entrepreneurial performance. We provide such understanding in three ways: by focusing on a specific entrepreneurial context (franchise systems), by developing a multi-faceted theoretical framework and by highlighting a contingency that may affect the networking-performance link. We combine knowledge and learning perspectives with a networking perspective to develop and test a multi-faceted framework on the effects of franchisee networking with peers within a franchise system (‘peer networking’) on franchisee unit performance. In particular, we argue that the performance benefits that franchisees draw from networking with their peers vary between low, medium and high performing franchisees. We use ordinary least squares (OLS) and Quantile Regression analyses to test our hypotheses with empirical data from a Dutch franchise system. Our results confirm that structural, resource and relational facets of franchisee peer networking affect unit performance, and that they benefit and harm low, medium, and high performing franchisees differently. 相似文献

This paper reports on a study that seeks to assess an extended typology of consumer social networking engagement behaviors. Drawing on uses and gratifications theory, this study assesses consumer engagement with social media, where consumer engagement incorporates consumer responses to marketing communications. The paper argues that certain motivations for social media use serve as antecedents to general attitudes toward social networking sites, which subsequently affects attitudes toward marketers' social networking sites. These attitudes then influence subsequent consumer engagement behaviors. The results show that social facilitation motivation, participating and socializing motivation, and information motivation positively influence consumers' general attitudes toward social networking sites, which had a strong effect on their attitude toward marketers' social networking sites. The relationship between attitudes toward social networking sites and engagement with social networking sites was mediated by attitudes toward marketers’ social networking sites also mediated. The current study brings together the online advertising perspective and the consumer motivation/gratifications perspective of using social media in branding and marketing into a conceptual model that holds up to empirical testing. The paper ends with a discussion of some limitations of the study and proposes avenues for future research. 相似文献

Sales professionals are embedded in an array of social interactions through their networking behaviors, yet the literature's understanding of these effects on job-based attitudes is relatively limited. Further, research suggests that men and women, not only network differently, but also often benefit in different ways from networking. This study examines the extent to which gender moderates the relationships between three forms of salesperson networking behaviors, job satisfaction, and organizational commitment. The data from a survey of 179 salespeople indicates that networking behaviors are related to job satisfaction and commitment in sales. However, the relationships vary for male and female salespeople. When analyzed separately, job satisfaction relates positively to professional networking for women, while job satisfaction relates positively to peer networking for men. In addition, peer networking directly relates to organizational commitment for women, rather than mediated by job satisfaction. 相似文献
