Peer-to-Peer (P2P) networks are becoming more and more popular in video content delivery services, such as Video on Demand (VoD). Scalability feature of P2P allows a higher number of simultaneous users at a given server load and bandwidth to use stream service. However, the quality of service (QoS) in these networks is difficult to be guaranteed because of the free-riding problem that nodes download the recourses while never uploading recourses, which degrades the performance of P2P VoD networks. In this paper, a distributed trust model is designed to reduce node's free-riding phenomenon in P2P VoD networks. In this model, the P2P network is abstracted to be a super node hierarchical structure to monitor the reputation of nodes. In order to calculate the reputation of nodes, the Hidden Markov Model (HMM) is introduced in this paper. Besides, a distinction algorithm is proposed to distinguish the free-riders and malicious nodes. The free-riders are the nodes which have a low frequency to free-ride. And the malicious nodes have a high frequency to free-ride. The distinction algorithm takes different measures to response to the request of these two kinds of free-riders. The simulation results demonstrate that this proposed trust model can improve QoS effectively in P2P VoD networks.

본 연구의 목적은 국내 공예작가들을 대상으로 예술가 명성(artistic fame) 형성의 주요 요인에 대해 탐색하는 것이다. 명성이란 행위자의 이름이 널리 알려지는 것을 의미하며, 평판은 사회적 평가 (social evaluation)의 일종으로, 행위자에 대한 평판은 평가의 주체에 따라 달라질 수 있다. 저자들은 먼저 이러한 선행연구를 통해 평판과 명성의 관계를 정립하고, 11명의 전문가 인터뷰를 실시하여 국내 공예작가의 명성 형성에 대해 탐색하였다. 질적 연구를 통해 국내 공예작가의 명성 형성에 영향을 미치는 주요 요인으로는 전문가 평판(expert reputation), 시장 평판(market reputation), 동료 평판(peer reputation)이 있음을 알 수 있었다. 뿐만 아니라, 작가 개인의 평판을 위한 노력(reputational work)도 명성 형성에 영향을 미친다는 선행연구와 인터뷰 내용을 바탕으로 명성과 평판, 평판, 노력간의 관계에 대한 가설을 수립하였다. 특히, 본 연구에서는 위에 제시된 세 종류의 외부 평판과 작가자신의 평판 노력이 명성에 미치는 영향을 평가하는데 있어, 작가의 출신 학교에 따른 차이점에 주목한다. 국내 340명의 공예협회등록 작가를 대상으로 개개인의 프로필 데이터를 수집하고 관련 변수를 측정하여, 연구가설에 대한 검증을 회귀분석을 통해 실시한 결과, 엘리트 대학(서울대, 홍익대) 출신 그룹에서는 기관 경력에 기반한 동료 평판과 '김달진 미술연구소' 사이트 프로필 게재와 같은 작가의 노력이 중요한 명성 형성 요인임이 밝혀졌다. 반면, 비 엘리트 그룹에서는 공신력, 영향력, 인지도가 바탕이 된 전문가 평판 (i.e., 수상경력), 시장 평판 (i.e., 초대전 경력), 그리고 자비로 개최한 개인전의 횟수가 명성 형성의 주요 요인으로 나타났다.

This study is an attempt to explore the nature and characteristics of strategic impact of green strategy by environmental capital, corporate reputation, and technology strengths on the firm's performance across countries. The main question addressed in this paper relates to how corporate sustainability, corporate reputation, technology strength, and capabilities influence the firm's economic performance with respect to diverse dimensions of performance measures including sustained growth through the leading firms across countries in the United States, Canada, Europe, and Asia-Pacific countries. Particularly, this study attempts to empirically explore the directions and magnitudes of the operational links between new emerging strategic core competencies (e.g., sustainability green strategy by environmental focus for more sustainable path, corporate reputation by corporate social responsibility and image enhancement, and technology strengths to develop a new product and market) and the firm's economic performance with respect to diverse dimensions of performance such as accounting (ROE and EOA) - and market-based performance (Market value and Tobin's q). Considering all possible limitations that might exist with regard to selected samples and methods, this study demonstrates that environmental sustainability, corporate reputation, technological capabilities and competencies through R&D intensity and patent are most likely to be significantly associated with most market-based performance measures, but the strategic significance of other variables such as capital intensity, leverage, and administrative cost efficiency on performance tends to be different depending on which performance measure is used across different countries with diverse economic and business contexts.

This research focuses on the importance of corporate social responsibility in building the company's reputation. Experts have studied CSR as an antecedent of a company's reputation, but the mechanisms underlying this process are rarely explored. Therefore, to fill this research gap, we demonstrate CSR's implementation combined with organizational justice based on discrepancy and equity theory. This study involved 210 employees in a family company. The study's analysis method uses Structural Equation Model (SEM), SmartPLS, with a five-step measurement and analysis procedure. The variables in this study are CSR implementation, organizational justice, employee trust, firm reputation, organizational objectiveness, organizational commitment, job satisfaction, and job performance. The results found that some of the direct relationships stated were not significant, but all demonstrations of indirect links were substantial. Besides, optimal CSR and organizational justice provide a reliable and positive domino effect in increasing the role and consequences of employee trust and firm reputation. The findings in this study confirm that upstream-downstream job performance causality can be successfully achieved if job satisfaction has been realized, job satisfaction can be achieved if organizational commitment can also be recognized, and organizational commitment can be developed. Reflection and influence, rather than organizational attractiveness becomes essential.

Social commerce (s-commerce) is a subset of e-commerce and uses social media for social interactions. Although s-commerce has been rapidly growing, disputes between some s-commerce firms and their consumers often occur over issues such as poor customer services, incorrect product information, and late refunds. In order for s-commerce to continuously grow, s-commerce firms need to build consumer-trust in their transaction process to minimize their consumers' uncertainty. The purpose of this study is to examine the relationships between the multidimensional trust (ability, integrity, benevolence) and the intention of continuous use of s-commerce. Moreover, this study presents antecedent factors needed for trust-building by applying the characteristics of s-commerce, and verifies the relations between the variables. We test and validate the research model and related hypotheses using structural equation modeling based on a survey done on 428 people who have previous experience with s-commerce. The result shows that trust has positive effect on the intention of continuous use, and verifies the necessity of the antecedent factors (social presence, assurance, informativeness, economic feasibility, and seller reputation) for trust-building. This study provides strategy for the continuous growth of s-commerce, and suggests theoretical implication that explains the relationship between the characteristics of s-commerce and consumers.

Purpose Virtual communities change the way people communicate and share information. The purpose of this paper is to find how internet social capital and individual motivations influence the information sharing in virtual communities. This study considers the social capital theory, individual motivations, information sharing, and community promotion to construct a theoretical model. Design/methodology/approach Social capital focuses on three dimensions that include 6 factors: social interaction ties, centrality, shared language, shared vision, trust and reciprocity. Individual motivations include 2 factors: reputation and enjoy helping. To confirm the research model and the hypotheses, 426 effective questionnaires were used for the final analysis. Findings The result of data analysis demonstrates that social interaction ties, centrality, shared language, trust, and reciprocity were significant in affecting information sharing behaviors. However, reputation, enjoy helping, and shared vision does not appear to have a significant influence on information sharing behaviors. The information sharing was positively related to community promotion.
