With the development of big data and social computing, large-scale group decision making (LGDM) problems attract much attention and become merging with social networks or behavioral factors. In this ...paper, by considering the trust of social behavioral factor, a two-stage trust network partition algorithm is proposed to reduce the complex of LGDM problems. The large-scale decision makers (DMs) are classified into some leader–follower sub-networks through a network partition algorithm. And a solution method based on trust relationship is proposed to keep the independency of the sub-networks when one follower belongs to more than one leader. Next, weights of independent sub-networks and their individual members are computed, and are further used to aggregate the comprehensive decision information. Finally, alternatives of LGDM problems are sorted with the comprehensive decision information. An experiment with MovieLens data is given to illustrate the proposed LGDM algorithm. And a comparison analysis with general clustering method is provided to verify the effectiveness and feasibility of the proposed method.
The increasing importance of entrepreneurial behaviour has led scholars to embrace the idea that an entrepreneurial orientation (EO) is an important predictor of firm performance. While EO occupies a ...central position in strategic entrepreneurship research, scholars have yet to explore its origins in new ventures. Drawing on the knowledge‐based and cognitive views, we theorize that a new venture team's transactive memory system is a cognitive mechanism that spurs the development of an EO. In a field study of high‐tech new ventures in China, we examined the relationship between venture teams’ transactive memory systems (representing the distribution, integration, and utilization of the teams’ knowledge) and EO and the moderating influence of team‐, firm‐, and environment‐level factors. We found that the transactive memory system of a new venture team enhanced their EO and that this relationship was positively influenced by intra‐team trust, the structural organicity of a venture, and environmental dynamism. Our findings provide novel insights into the micro‐foundations of TMS in developing an EO in new ventures.
Citizens’ levels of mistrust toward the media, as well as their perception of media bias, have increased in past years in most Western democracies. This study explores how these negative observations ...on journalism may influence their use of traditional, citizen, and social media for news. Drawing on two-wave U.S. panel data, results suggest that media trust and perceived bias relate to media consumption differently. Trust in social and citizen media positively predicts use of news via social media, but has no effect on traditional or citizen news use. By contrast, perceived media bias is associated with decreased news use overall.
This paper investigates the relationship between institutional trust in the health-care system, i.e. an institutional aspect of social capital, and self-rated health, and whether the strength of this ...association is affected by access to health-care services. The 2004 public health survey in the Scania region of Sweden is a cross-sectional study; a total of 27,963 respondents aged 18–80 years answered a postal questionnaire, which represents 59% of the random sample. Logistic regression model was used to investigate the association between institutional trust and self-rated health. Multivariate analyses of self-rated health were performed in order to investigate the importance of possible confounders (age, country of origin, education, economic stress, generalized trust in other people, and care-seeking behaviour) on this association. A 28.7% proportion of the men and 33.2% of the women reported poor self-rated health. A total of 15.0% and 58.3% of the respondents reported “very high” and “rather high” trust in the health-care system, respectively. Almost one-third of all respondents reported low institutional trust. Respondents born outside Sweden, with low/medium education, low generalized trust and low institutional trust had significantly higher odds ratios of poor self-rated health. Multiple adjustments for age, country of origin, education, economic stress, and horizontal trust had some effect on the significant relationship between institutional trust and poor self-rated health, for both men and women, but the additional introduction of care-seeking behaviour in the model substantially reduced the odds ratios. In conclusion, low trust in the health-care system is associated with poor self-rated health. This association may be partly mediated by “not seeking health care when needed”. However, this is a cross-sectional exploratory study and the causality may go in both directions.
The relationship between a buyer and its suppliers often relies on factors beyond the terms of a contractual agreement. Buyers can therefore benefit from identifying trustworthy suppliers. We argue ...that precontractual actions by a supplier, for example making costly buyer-specific investments without a long-term contract, can signal a supplier’s trustworthiness. We develop a theoretical model to reflect supplier trustworthiness, and determine when a buyer can benefit from identifying trustworthy suppliers. We show that costly relationship-specific investments can serve as a signal of trustworthiness, and that supply chain profits increase when trustworthy suppliers are able to identify themselves in this fashion. We demonstrate the importance of the signaling mechanism using laboratory experiments. The experimental results show that relationship-specific investments lead to more collaborative transactions, with buyers offering higher prices and suppliers returning higher-quality products. This results in increased profits for both buyers and suppliers. Additionally, we design a treatment which shuts down the signaling mechanism and show that the benefits of the buyer-specific investment are no longer present in this case. Finally, we show that the benefits of buyer-specific investments for both suppliers and buyers are strengthened when firms interact repeatedly.

The sudden shift from physical office location to a fully remote or hybrid work model accelerated by the COVID19 pandemic, is a phenomenon that changed how organizations traditionally operated and ...thereby introduced new vulnerabilities and consequently changed the cyber threat landscape. This has led organizations around the globe to seek new approaches to protect their enterprise network. One such approach is the adoption of the Zero Trust security approach due to its many advantages over the traditional/perimeter security approach. Although zero trust presents a stronger defense approach over the perimeter security model, organizations are hesitant to fully embrace it. This is partly due to the lack of a unified zero-trust implementation framework that can be used to guide its adoption. As such, we conducted a multivocal review that included literature from both academic and non-academic sources to consolidate knowledge on the state-of-the-art of zero-trust implementation and identify gaps in literature. Our result shows that existing papers tend to have a narrow viewpoint on the approach of implementing zero trust, rather than an encompassing viewpoint that can provide a more holistic view on the topic. We developed a conceptual framework that articulates the five core components involved in the implementation of zero trust security, guided by key questions designed to guide the implementation process.
Believers of karma believe in ethical causation where good and bad outcomes can be traced to past moral and immoral acts. Karmic belief may have important interpersonal consequences. We investigated ...whether American Christians expect more trustworthiness from (and are more likely to trust) interaction partners who believe in karma. We conducted an incentivized study of the trust game where interaction partners had different beliefs in karma and God. Participants expected more trustworthiness from (and were more likely to trust) karma believers. Expectations did not match actual behavior: karmic belief was not associated with actual trustworthiness. These findings suggest that people may use others’ karmic belief as a cue to predict their trustworthiness but would err when doing so.

Customer engagement has become a topical issue in the marketing literature in recent times. Many researchers have called for more research to be done on the antecedents of customer engagement. In ...response to this call, we examine the impact of trust on customer engagement. We used the survey research design to address the research question. We used the intercept approach to select the participants of the study. We collected the data from retail banking customers in Ghana. The hypotheses were tested using Structural Equation Modelling (SEM). The findings of this study show that trust in service providers and economy-based trust have a significant and positive effect on emotional engagement, cognitive engagement, and behavioural engagement. The implications of the findings have been discussed at the end of the paper.
The current debate about declining media trust is related not only to the disruptive changes in the media but also to the general decline of trust in institutions and politicians. This article ...combines the perspectives of media trust and political trust, by examining to what degree voters perceive politicians as “honest” in the contexts of various media and communication forms. Comparing the voters’ evaluation of politicians’ trustworthiness in talk shows, news interviews, speeches, flyers, social media, and opinion pieces makes it possible to measure the impact of media contexts on the level of trust. A key finding is that voters deem politicians as more honest in social media and opinion pieces, compared to talk shows and news interviews. Second, voters tend to evaluate politicians as more honest in the media formats they most often consume; a finding that confirms the virtuous circle theory; young people typically found politicians to be more dishonest in mainstream media compared to social media A third finding is that the voters tend to evaluate populist politicians as more authentic than traditional politicians and that female politicians were regarded as more authentic compared to male politicians. These findings have implications both for journalistic ideals for coverage of politics in and for political strategic communication.
Natural personal care products are gaining popularity due to their benefits in terms of health and well-being. However, consumers are wary of these products and are guided by the fake news ...circulating about them. Since natural product consumption offers several personal and environmental benefits, it would be worthwhile to understand consumers’ tendency to let fake news influence their consumption decisions. Accordingly, the current study examined the association of fake news and purchasing behaviour towards natural personal care products, utilising Stimulus-Organism-Behaviour-Consequence (SOBC) as the theoretical framework. The study proposed openness to change as the stimulus, perceived benefits and perceived risks as organismic internal states, purchase intentions as the behaviour, and the propensity of believing and acting on fake news as the consequence, which is further associated with system trust. The model was tested by analysing data collected from 390 existing consumers, considering the moderation effect of brand trust and controlling the effect of age and gender. The findings confirmed that openness to change is associated with perceived benefits and risks. Furthermore, perceived benefits and system trust are associated with purchase intentions, which are, in turn, associated with the propensity of believing and acting on fake news. The study presents several novel contributions to theory and practice.
