Motivated by the practice that e-sellers cooperate with insurance companies to offer consumers the return-freight insurance(RI),this paper aims to investigate the competing e-sellers’RI strategies.Regarding the information asymmetry in the online context,reputation system is widely applied by e-platforms.In an online market with two competing e-sellers that sell the same product but are differentiated in their reputation,this paper builds an analytical model to explore the e-sellers optimal pricing and RI strategies.Combined with sellers’reputation and their RI strategies,the equilibrium outcomes under four cases are discussed.This paper reveals the conditions that e-sellers are willing to offer RI.Specifically,the findings demonstrate that low reputation e-seller is more likely to offer RI.Moreover,when the sellers are more divergent,they are more likely to co-exist in the market.Insurance premium and RI compensation play critical roles in their decisions.RI introduction tends to increase the price,thus offsets the benefits of RI,but does not affect the total consumer surplus.

Countries implement corporate communication initiatives to improve their international relations,achieve different business objectives,and reinforce their brands.Nation branding activities are mainly based on international events:sport,culture,social issues.This paper evaluates the Expo 2020 Dubai’s impact on the United Arab Emirates’brand.We conducted a literature review about nation branding,and then we resorted to 15 indicators to analyze how the most important newspapers from some of the most influential countries(United States,Russia,France,and Germany)covered this event from a journalistic and corporate communication perspective.Our results proved that 82 articles were published about this topic,and the most common criteria respected were quoting organizers(n=61),using the Expo’s logo(n=45)and the image of a falcon(n=43).We concluded that most media companies focused on facts related to the Expo and did references to the country’s identity(values,flag,falcon),but most of them did not include links to the Dubai Expo’s and UAE public authorities’websites.

Volunteered geographic information(VGI)has entered a phase where there are both a substantial amount of crowdsourced information available and a big interest in using it by organizations.But the issue of deciding the quality of VGI without resorting to a comparison with authoritative data remains an open challenge.This article first formulates the problem of quality assessment of VGI data.Then presents a model to measure trustworthiness of information and reputation of contributors by analyzing geometric,qualitative,and semantic aspects of edits over time.An implementation of the model is running on a small data-set for a preliminary empirical validation.The results indicate that the computed trustworthiness provides a valid approximation of VGI quality.

A reputation evaluation method based on multi-dimensional information representation and correlative algorithm is proposed for open multi-agent systems. First, a vector model is estab- lished to represent the reputation related information. Second, a vector based reputation model ＂TRUST＂ is put forward to evaluate the reputation of agents. Finally, a correlative algorithm for se- lecting the most appropriate service provider is proposed. Simulation results indicate that the method can quickly and accurately to achieve the aim of adaptive immunity to reputation fraud and improving the average gain that service consumer agents obtained.

reputation mechanisms are a key technique to trust assessment in large-scale decentralized systems. The effectiveness of reputation-based trust management fundamentally relies on the assumption that an entity＇s future behavior may be predicted based on its past behavior. Though many reputation-based trust schemes have been proposed, they can often be easily manipulated and exploited, since an attacker may adapt its behavior, and make the above assumption invalid. In other words, existing trust schemes are in general only effective when applied to honest players who usually act with certain consistency instead of adversaries who can behave arbitrarily. In this paper, we investigate the modeling of honest entities in decentralized systems. We build a statistical model for the transaction histories of honest players. This statistical model serves as a profiling tool to identify suspicious entities. It is combined with existing trust schemes to ensure that they are applied to entities whose transaction records are consistent with the statistical model. This approach limits the manipulation capability of adversaries, and thus can significantly improve the quality of reputation-based trust assessment.

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 mutually establish trust relationships based on their past experience. Current approaches for the reputation management cannot achieve the fine granularity and verifiability for each individual user, in the sense that the reputation values on such OSNs are coarse and lack of credibility. In this paper, we propose a fine granularity attribute-based reputation system which enables users to rate each other＇s attributes instead of identities. Our scheme first verifies each OSN user＇s attributes, and further allows OSN users to vote on the posted attribute-associated messages to derive the reputation value. The attribute verification process provides the authenticity of the reputation value without revealing the actual value to entities who do not have the vote privilege. To predict a stranger＇s behavior, we propose a reputation retrieval protocol for querying the reputation value on a specific attribute. To the best of our knowledge, we are the first to define a fine-grained reputation value based on users＇ verified attributes in OSNs with privacy preservation. We provide the security analysis along with the simulation results to verify the privacy preservation and feasibility. The implementation of the proposed scheme on current OSNs is also discussed.

With the known evidence that potential connected vehicle(CV)users are worried about sharing data because of the associated data privacy and security issues,this study investigates the importance of the reputation of the data manager(who collects,stores,and owns the data)of CV technology(CVT).Based on a questionnaire survey of 2400 US adults,this study asserts that the data manager's reputation has a significant impact on the public perception of data privacy and security issues in CVT along with overall CV acceptance.The results show that data privacy issues have a more negative impact on CV acceptance than data security issues.In addition,the reputation of a data manager has a bigger role in the eyes of the public in shaping their perception of data privacy in comparison to data security.Based on the results,the public considers data privacy as the responsibility of the data manager to protect their data from unauthorized/illegal third-party access,whereas data security is the technological strength of CVT to protect the data from hacking.Finally,it is recommended that CV stakeholders take actions to improve potential CV users'confidence in the privacy of data shared by disclosing the data management process,data privacy protection efforts,building public trust in the data manager,and introducing/enforcing laws regarding data privacy protection.

According to the risk management and reputation insurance theory of corporate social responsibility, corporate donations can help a company to repair its reputation after a crisis.This study uses a propensity score matching–difference in difference(PSM + DID) methodology to investigate the charitable donation activities of companies that have been subject to regulatory penalties.The analysis of a sample of A-share listed companies in the 2004–2016 period shows that companies significantly increase their charitable donations after regulatory penalties, but this effect weakens over time.Further analysis reveals that non-state-owned companies, companies with higher ownership concentrations, and companies receiving severer penalties are more motivated to make donations after regulatory penalties.By studying the reputation repair behavior of companies that have been subject to regulatory penalties, this study offers further support for the risk management and reputation insurance theory of corporate social responsibility.It also enriches our understanding of companies’ active responses to regulatory penalties and provides insights into companies’ motives for making charitable donations.

Security has been the focus of grid systems recently. As a kind of tool, grid security infrastructure （GSI） provides the authentication and authorization services and so on. These mechanisms mostly belong to the objective factors, which have not met the needs of security. As the subjective factor, trust model plays an important role in security field. A new two-level reputation trust architecture for grid is given to reduce the costs of system management largely, in which trust relationships amongst virtual organizations （VOs） are built on domain trust managers （DTMs） rather than resource nodes （RNs）. Taking inter-domain trust propagation for example, trust model is improved by integrating global reputation and the subjective trust concept of each recommender into synthesizing final trust value. Moreover, before the grid starts to interact with the trustworthy entities, the pre-measure scheme is presented to filter distrustful entities further, which is based on accuracy and honesty. Experimental results indicate that the model can prevent from the malicious attacks better.

Food hygiene incidents in hot pot restaurants were studied,and a relationship model between corporate reputation and consumers behavioral intention was established.Hot pot consumers of hot pot restaurants were surveyed through questionnaires.The results show that corporate reputation positively affects service recovery and repurchase intention,and service recovery positively influences repurchase intention,while corporate reputation affects repurchase intention through service recovery.In other words,under the situation of enterprise crises,the service recovery of an enterprise can restore its image and reputation.Therefore,when an enterprise has a crisis,it should positively respond to the crisis incident,and take timely crisis recovery to maintain its positive image.
