This study aims to explore the concepts and nature of records in digital environments based on analyzing recent theoretical studies of records. This is not intended to defining records for management in a specific environment. This study is divided into two parts. Firstly, it classifies the definitions of records in three perspectives; evidence, information, and representation of activities, and explores the concepts and theoretical backgrounds underlying each definition. Secondly, it articulates some implications for understanding the concept and nature of records in digital environments by four categories such as i) fixity, ii) materiality, iii) activity and context, and iv) trustworthiness, which were derived from the definition of "persistent representation of activities" by Geoffrey Yeo.

This study investigates the safety of Hanwoo beef and consumer satisfaction through the questionnaire for 280 consumers of Hanwoo beef in Gyeongsangbuk-do. Among 280 copies, only 245 copies were adopted to analyze. The subjects consisted of 82(33.2%) males and 163(66.5%) females and their age 55(22.4%) of twenties, 52(21.2) of thirties, 86(35.1%) of forties and 52(21.2%) of over fifties. The frequency of purchasing Hanwoo beef was that as consumers were getting older, they tended to purchase more beef. The most popular place for purchasing Hanwoo beef was Hanwoo specialty stores(55.1%), but there was no statistical difference. The most favorite retail cuts for Hanwoo beef was Loin(44.5%), followed by ribs(26.1%). The consumers thought that selling imported beef turned into Hanwoo beef occurred 70.2%(sometimes), and 20.8%(yes), 6.1%(don't know) and 2.9%(never). For a method to prevent it, the traceability system(60.4%) was the highest, followed by country of origin labelling(16.3%). Taking the perfect score 5 points about the country of origin marks and traceability, trustworthiness which was presented the highest points was 3.31, recognition 3.29, experience 3.26 and practical effect 3.07. The average of two systems was 3.23. The average points of the safety and consumer trustworthiness of Hanwoo beef were 2.96 points and 3.13 respectively. The safety and the consumer trustworthiness showed statistically significant difference according to educational background, income, and jobs. From the results obtained in the current study, it is concluded that if the traceability system and country of origin labelling are managed well by the government, safety and consumer trustworthiness will be improved.

Purpose - This study aimed to investigate the effect of entrepreneurial temperament (ET) such as innovativeness, risk-taking, and proactiveness in entrepreneur's lifetime before start-up and the effect of social capital (SC) such as network ties and trustworthiness on entrepreneurial intention. Research design, data, and methodology - We examined the components of ET (innovativeness, risk-taking, and proactiveness) and components of SC (network ties and trustworthiness) through existing prior research and investigated the factors that affected entrepreneurial intention. The first hypothesis of this study was that entrepreneurial temperament will have a significant impact on network ties of social capital, and the second hypothesis assumed that entrepreneurial temperament will have a significant effect on the trustworthiness of social capital. Finally, the second hypothesis assumed that social capital will have a significant impact on entrepreneurial intentions. We collected 175 data using questionnaires for people who have not yet started a start-up. And we used the Structure Equation Modeling (SEM) to evaluate the collected data and to test the research model by the two step research procedure. Results - As a result, the innovativeness and proactiveness of ET have a significant effect on network ties and trustworthiness of SC, but the effect of risk-taking on risk-taking of SC is not significant. On the other hand, network ties and network ties of SC was revealed a significant effect on the EI. Conclusions - The implications of this article could be observed as mentioned in this paper. First, we found that entrepreneurial innovativeness and proactiveness are helpful in constructing SCs, but not risk-taking. These results demonstrated that ET of entrepreneurs is important factor in the formation of social capital. Second, the SC that an entrepreneur built before the start-up has a meaning for EI. In conclusion, ET was affected partially to EI mediated SC. It is academic in that ET and SC are independent from each other and have a mediating role between ET and EI, unlike those directly affecting EI. Although some important implications were found in this study, this study had some limitations and we hope that future research will be complemented.

Inauthentic resources can be easily spread by P2P (Peer-to-Peer) participants due to the openness and anonymity of P2P networks. A possible way to restrict the distribution of inauthentic resources and prevent malicious peers from joining P2P networks is to exploit peers' reputation which reflect their past behaviors and are also helpful to predict peers' future behaviors. There is a possibility that some peers intentionally plays along with other peers in order to increase/decrease its reputation through false feedback exchanges. Therefore, we propose a new reputation management scheme, called TrustRRep (Trustable Resource sharing service using Reputation) scheme, which improves the trustworthiness and efficiency of P2P networks by identifying peers who give false feedback. The TrustRRep scheme is also capable of providing peers with the trustworthiness of shared resources by discriminating resources distributed by malicious peers. We implement the proposed TrustRRep scheme on the NS-2 simulator for evaluating its performance compared to the recent reputation management work available in literature. A case study on simulations shows that the proposed reputation management scheme yields efficient performance in terms of the minimal download ratio and dissemination of inauthentic resources, the efficient identification of peers who give false feedback, and the provisioning of the trustworthiness of peers' reputation. It also shows that the proposed TrustRRep scheme imposes the restrictions of participating P2P networks on a malicious peers by diminishing its trust value.

LOD(Linked Open Data) is composed of RDF triples which are based on ontologies. They are identified, linked, and accessed under the principles of linked data. Publications of LOD data sets lead to the extension of LOD cloud and ultimately progress to the web of data. However, if ontologically the same things in different LOD data sets are identified by different URIs, it is difficult to figure out their sameness and to provide trustworthy links among them. To solve this problem, we suggest a Trustworthiness Improving Link Evaluation, TILE for short, technique. TILE evaluates links in 4 steps. Step 1 is to consider the inference property of syntactic elements in LOD data set and then generate RDF triples which have existed implicitly. In Step 2, TILE appoints predicates, compares their objects in triples, and then evaluates links between the subjects in the triples. In Step 3, TILE evaluates the predicates' syntactic property at the standpoints of subject description and vocabulary definition and compensates the evaluation results of Step 2. The syntactic elements considered by TILE contain RDFS, OWL, OWL2 which are recommended by W3C. Finally, TILE makes the publisher of LOD data set review the evaluation results and then decide whether to re-evaluate or finalize the links. This leads the publishers' responsibility to be reflected in the trustworthiness of links among the data published.

There is a tradeoff between user's privacy and utility of context-aware services in ubiquitous computing environments. Many privacy models have been proposed to support the disclosure of personal information at different levels of detail, in ubiquitous computing environments. However, most of these models do not allow for explicit criteria to assess the benefit users are likely to reap by disclosing their personal information. In this paper, we propose an automated decision making mechanism that evaluates the "benefit of disclosure" for the users based on trust relationships between users and information requesters and manages the disclosure of user's personal information accordingly. Unlike other trust models, we do not regard the reputation of an information requester as sufficient to determine his/her trustworthiness. Instead, we represent trustworthiness as a function of information requester's reputation in the eyes of the user and his/her competence in a given context. To validate our mechanism, we apply it to context-aware healthcare application that monitors physiological condition of a user.

Network marketing in Indonesia, especially in a time of crisis, is massively rising and has become a popular opportunity among other industries. Network marketing organizations, consists of partnership and trust, a community of connections and contact between individuals. This article has tried to examine the potential strategy to mitigate low trust in network marketing organizations specifically in the Indonesia market, where no studies on the subject has been done before. In doing this research assignment employed a secondary research methodology by reviewing previous academic literatures, by exploration and evaluation. For the purpose, 6 main articles and 25 relevant supporting articles were selected, there is an interesting and prominent research in an effort to repair trust in the perspective of the organization's efforts to build trust and control trust framework in strategy trust repair. The result of this analysis showed that the application of trust-building activities studies reveals how trust-building behavior is related to controls and how the efforts towards fostering subordinate cooperation are motivated by different types of controls and display of trustworthiness. It can be concluded that by implementing this trust repair model consistently and with a full commitment, it can gradually restore people's trust in the network marketing industry, sustain industry existence and exalted purpose of this industry can be achieved.

As the number of services available on the Web increases, it is vital to be able to identify which services can be trusted. Since there can be an extremely large number of potential services that offer similar functionality, it is challenging to select the right ones. Service requestors have to decide which services closelysatisfy their needs, and theymust worry about the reliability of the service provider. Although an individual service can be trusted, a composed service is not guaranteed to be trustworthy. In this paper, we present a trust model that supports service discovery and composition based on trustworthiness. We define a method to evaluate trust in order to discover trustworthy services. We also provide a method to perform trust estimation for dynamic service composition, and we present results of two experiments. The proposed model allows for service requestors to obtain the most trustworthy services possible. Our mechanism uses direct and indirect user experience to discover the trustworthiness of the services and service providers. Moreover, composing services based on quantitative trust measurements will allow for consumers to acquire a highly reliable service that meet their quality and functional requirements.

An international survey of over 3600 academic researchers examined how trustworthiness is determined when making decisions on scholarly reading, citing, and publishing in the digital age and whether social media and open access publications are having an impact on judgements. In general, the study found that traditional scholarly methods and criteria remain important across the board. However, there are significant differences between younger (age 30 & under) and older researchers (over 30). Thus younger researchers: a) expend less effort to obtain information and more likely to compromise on quality in their selections; b) view open access publishing much more positively as it offers them more choices and helps to establish their reputation more quickly; c) compensate for their lack of experience by relying more heavily on trust markers and proxies, such as impact factors; d) use all the outlets available in order to improve the chances of getting their work published and, in this respect, make the most use of the social media with which they are more familiar.

A book review is one of the most important sources of information which provide the descriptive and evaluative contents about books. Reviews have great influence on consumer behavior because they are believed to be more reliable than information provided by sellers. Readers who read a book review includes information about book decide whether they will buy or not. This study examines customer attitude change by book reviews with regarding to different type of information sources(experts and prior customers) and different directions of messages. We address the following research questions: (1) Can positive book reviews with credibility have a positive impact on acceptance of books? (2) Can negative book reviews with credibility have a negative impact on acceptance of books? The results shows that a credibility is an essential factor for affecting customers' mind. When positive book reviews were written, both expert and customer opinions have a positive impact on acceptance of customers. Given negative book reviews of experts, trustworthiness is more important than expertise. However, a objectivity of customer's reviews is more important.
