Perceptions of Neighbourhood Disorder and Reputation: Qualitative Findings from Two Contrasting Areas of an Australian City

Within Australian cities, social and economic inequalities manifest themselves spatially. Perceived neighbourhood disorder and neighbourhood reputation are relevant to considering the ways in which social and economic inequalities translate into place-based inequalities. This article explores the ways in which residents of two socio-economically contrasting urban areas describe and explain neighbourhood disorder and neighbourhood reputation. It draws upon qualitative data from 40 in-depth interviews, in addition to quantitative data from a postal survey. The qualitative findings highlighted how issues of neighbourhood disorder and reputation were intertwined. In both areas, participants sought to portray themselves and their neighbourhoods in positive ways, by attributing responsibility for neighbourhood disorder to people who were unlike themselves, and by highlighting places that were perceived to have worse reputations and higher levels of disorder. The findings are considered in light of Bourdieu's theory of capitals. This article indicates that both neighbourhood disorder and reputation are pathways through which social, economic and health inequities are maintained in urban areas.     

A Privacy-Preserving Attribute-Based Reputation System in Online Social Networks

Online social networks (OSNs) have revolutionarily changed the way people connect with each other. One of the main factors that help achieve this success is reputation systems that enable OSN users to ...     

A simulation testbed for analyzing trust and reputation mechanisms in unreliable online markets

Modern online markets are becoming extremely dynamic, indirectly dictating the need for (semi-) autonomous approaches for constant monitoring and immediate action in order to satisfy one’s needs/preferences. In such open and versatile environments, software agents may be considered as a suitable metaphor for dealing with the increasing complexity of the problem. Additionally, trust and reputation have been recognized as key issues in online markets and many researchers have, in different perspectives, surveyed the related notions, mechanisms and models. Within the context of this work we present an adaptable, multivariate agent testbed for the simulation of open online markets and the study of various factors affecting the quality of the service consumed. This testbed, which we call Euphemus, is highly parameterized and can be easily customized to suit a particular application domain. It allows for building various market scenarios and analyzing interesting properties of e-commerce environments from a trust perspective. The architecture of Euphemus is presented and a number of well-known trust and reputation models are built with Euphemus, in order to show how the testbed can be used to apply and adapt models. Extensive experimentation has been performed in order to show how models behave in unreliable online markets, results are discussed and interesting conclusions are drawn.     

面向企业信息系统集成的Web服务推荐模型

为解决企业信息系统集成过程中Web服务选择方面的问题,提出了一种基于服务质量与用户推荐的服务推荐模型。根据服务质量量化模型计算服务质量综合值,利用皮尔逊相关系数找出一组评价相似用户,根据该组用户的评价相似度与评价值计算用户推荐度,利用服务质量综合值和用户推荐度计算Web服务信誉度,依据Web服务信誉度选出最优的Web服务。针对恶意推荐问题,提出一种用户评价可信度的计算方法。最后,根据该模型实现了一个推荐平台。实验结果表明该模型能够准确地为企业级用户推荐满足需求的Web服务。     

随机服务质量感知的Web服务信誉度量模型

为了根据公告服务质量随机性和实际服务质量随机性之间的一致性来计算服务质量的信誉,首先利用分布函数表示服务质量随机性,并给出一种服务质量经验分布函数的增量式更新方法。通过将服务质量公告值和实际观察值视为随机变量,并以随机优势理论为基础,设计结合随机服务质量公告及实际观察值的信誉度量模型。模型考虑了公告服务质量随机性和实际服务质量随机性之间不同的优势关系,以及服务质量观察值波动对信誉的影响。理论分析与实验验证了模型的合理性及其在服务选择中应用的有效性。     

基于索洛模型的品牌声誉形成机制研究

Examining corporate reputation judgments with generalizability theory.

The researchers used generalizability theory to examine whether reputation judgments about corporations function in a manner consistent with contemporary theory in the corporate-reputation literature. University professors (n = 86) of finance, marketing, and human resources management made repeated judgments about the general reputations of highly visible American companies. Minimal variability in the judgments is explained by items, time, persons, and field of specialization. Moreover, experts from the different specializations reveal considerable agreement in how they weigh different aspects of corporate performance in arriving at their global reputation judgments. The results generally support the theory of the reputation construct and suggest that stable estimates of global reputation can be achieved with a small number of items and experts.

基于统计推断的P2P信誉评估机制

利用简单的数理统计学知识建立计算模型,为P2P网络中每一个节点提供一个信誉值依概率出现的区间,对节点未来的行为预测,从而使得节点可以规避风险,减少恶意行为的发生.并且针对网络中的恶意攻击,提出了相应的解决方法.通过模拟实验证明了该模型具有良好的性能.     

社会声誉与高校筹资工作：关系、作用与机制

高校社会声誉与筹资规模密切相关,社会声誉越高,高校筹资规模也就越大。教育准公共物品的性质需要社会资金的投入,社会资金投入以高校社会声誉为信号,高校社会声誉引导着社会捐赠资金的投入。高校应当以社会声誉为基础,充分树立、维护和运用其社会声誉,开展各类捐赠活动,创新高校筹资工作机制,积极争取社会捐赠。     

基于公司股权变更后“三年效应”的几点思考

公司股权变更对公司业绩提高存在显著的“三年效应”，但是从第4年开始这种正丽效应开始消失。通过建立以年薪制为基础的股票期股薪酬制度和完善高级管理人员的声誉激励机制，构建高级管理人员的“双重激励机制”，解决尚缴管理人员的长期激劢和约束问题．从而达到提高公司长远业绩的目的。
