A great deal of effort has been made to introduce trust models to assess trustworthiness within virtual societies. The great majority of them makes extensive use of direct experience as the main source of information, considering recommendation/reputation and inferential processes just later, as a secondary mechanism to refine trust assessment. In this kind of networks, unfortunately, direct experience might not always represent the best solution to assess trustworthiness. In fact, their highly dynamic structure promotes an increase of the average number of interconnections among agents. This in turn negatively affects the degree of knowledge the agents possess about each specific individual, i.e. direct experience. To date, however, it has not been said much about how to face these situations.It is fundamental to find an effective approach for trust assessment even in lack of direct experience, which is the central focus of this research. By the means of a multi-agent social simulation, we consider the situation in which an agent can just access indirect knowledge for trust assessment, namely recommendations of specific individuals or whole categories of individuals. Then, we compare the efficiency of these two approaches in order to identify when it is more convenient to rely on the first or on the second one. As expected, our results confirm that the dynamic nature of these networks strongly affects the role of categories. We modeled this feature introducing the “turnover” in the simulations, whereby the higher is the turnover the more convenient it is relying on categories. Besides this confirmatory result, our simulations highlight the higher degree of robustness of categories in the presence of unreliable recommenders. Such a result is even more significant if there is no available information about how reliable the recommenders are.The results we obtained are in accordance with the current literature and can be of important interest for the development of this sector.  相似文献

Regarding evaluation, numerous researches highlighted the social valuation of the internality. From the end of 1990s, the diversification of the studied situations came to put in perspective the impact of this norm, while revealing the existence of others social norms. The present research was designed to investigate the phenomenon of social valuation of the deference in situation of annual performance review. The social valuation of the power of others was examined by two studies: one led from paradigm of autopresentation with employees and other one, conducted under legislator paradigm with Human Resources specialists (students in their final year of Institutes Business Administration). If the results indicate, in a classic way, important normative effects of the internality, the valuation of the deferential explanations is globally so obvious. These results question about the contextual expression of a norm of deference: employees and RH experts give weight to the power of others. The results show a convergent use of the internality and the power of others.  相似文献

ObjectivesGrounded in personal and social identity theory, the purpose of this study was to examine whether parents’ personal and social identity perceptions influence their moral intentions towards antisocial parent behaviour in a youth sport setting.DesignParents of competitive youth ice hockey players (N = 437) read a vignette that either described a parent from the participant’s own team (i.e., ingroup), or a parent from an opposing team (i.e., outgroup) acting antisocially towards an athlete from the participant’s own team, an opposing athlete, or their own child. Parents were asked whether they would respond to the antisocial behaviour in the form of direct or indirect criticism or report the behaviour to the coach or to the league.ResultsParents were more likely to directly criticize ingroup parents than outgroup parents and they were more likely to indirectly criticize outgroup parents than ingroup parents. Further, parents with stronger social identities reported higher intentions to indirectly criticize an outgroup parent. There were no main effects for reporting behaviour (to coach or league), and personal identity did not moderate relationships with moral intentions towards antisocial behaviour.ConclusionBy providing parents with a situation that includes antisocial parent behaviour in the immediate youth sport environment, novel insight was gathered with regard to what contextual elements might drive parents’ intention to criticize, but not report antisocial behaviour.  相似文献

PurposePrevious studies have indicated a relationship between the use of commercial physical activity apps (e.g., Fitbit, Strava) and physical activity engagement. The use of social components of such apps, in particular app-specific communities (connecting with other app users) and existing social networking platforms (e.g., Facebook) have the potential to enhance physical activity. This study aimed to explore the psychological mechanisms underlying the relationship between the use of commercial physical activity apps (and their social components) and physical activity engagement.MethodAn online cross-sectional survey assessed physical activity, use of commercial physical activity apps (and their associated social components), and psychological constructs (social support, self-efficacy, motivation, trait competitiveness, trait social comparison).Results1274 adults aged 18–83 years (Mage = 34.1 ± 13.5 years, 87.6% female) participated. App use was positively associated with physical activity engagement. The relationship between app use and physical activity was fully mediated by social support, self-efficacy, intrinsic motivation and identified regulation. Trait competitiveness, but not trait social comparison, moderated the relationship between app use and physical activity. Most features (e.g., sharing posts, providing or receiving encouragement) of the social components of apps were positively associated with psychological constructs linked to engagement in physical activity. Mediation pathways linking features of existing social networking platforms with physical activity were found. Specifically, sharing posts was linked to higher engagement in physical activity via positive associations with self-efficacy, and receiving encouragement with linked to higher engagement in physical activity via positive associations with both self-efficacy and identified regulation. In addition, engagement in comparisons was associated with lower self-efficacy and higher external regulation, and in turn, lower physical activity.ConclusionsThe relationship between the use of commercial physical activity apps and physical activity is underpinned by social support, self-efficacy and autonomous motivations. The findings highlight the importance of trait competitiveness, which should be taken into consideration when leveraging physical activity apps. Overall, the present study demonstrated that commercial physical activity apps (and their social components) hold great potential to increase physical activity engagement given their associations with psychological constructs strongly linked with physical activity.  相似文献

Servant leadership is characterized by a leader’s emphasis on serving their followers first. Within the sport context, servant leadership has been studied primarily in coaches and has been associated with positive athlete outcomes, such as increased athlete satisfaction, motivation, and performance. However, the impact of servant leadership from an athlete perspective (e.g., formal team captains) has been underexplored. As such, the purpose of the present study was to examine the relationships between peer servant leadership, cohesion, and social identity within intercollegiate athletes. Two hundred and eighty-eight Division I and Division III NCAA intercollegiate athletes participated in the present study (female n = 165; male n = 123; Mage = 19.41, SDage = 1.09) and completed the Revised Servant Leadership Profile for Sport (RSLP-S; Hammermeister et al., 2008), Group Environment Questionnaire (GEQ; Carron et al., 1985; Eys et al., 2007), and Social Identity Questionnaire for Sport (SIQS; Bruner & Benson, 2018). Structural equation modeling was used to assess the relationships between peer servant leadership, cohesion, and social identity. Results revealed that peer servant leadership positively predicted cohesion, and this relationship was fully mediated by social identity. The current study supports the effectiveness of peer servant leadership in sport contexts and provides theoretical support for the social identity approach to leadership.  相似文献

Studies have shown that repressors tend to respond to self-report tools in a positive fashion which distorts the findings of studies based on questionnaires. The present study aimed to examine the way repressors respond to “Self-relevant” scales (which assess variables related to adaptive self-function) in comparison to “Health-relevant” scales (which assess physical and psychological health). Iranian university students (N = 271) responded to the Weinberger Adjustment Inventory (to differentiate between repressors and self-assured individuals), Mindful Attention and Awareness Scale, Self-control Scale, Integrative Self-knowledge Scale and Self-compassion Scale (to measure self-relevant variables), Bartone Symptoms checklist and the Depression and Anxiety Subscales of Depression, Anxiety and Stress Subscale (DASS-21) (to measure health-relevant variables). Based on responses to the Weinberger Adjustment Inventory, 101 participants fell into two groups, including repressors and self-assured individuals, and their data were further analysed. Multivariate analysis of variance showed no difference in repressors' scores in health-relevant scales compared to the self-assured group (healthy individuals), but they reported higher scores in adaptive self-relevant scales compared to the self-assured individuals. This study provides new evidence that compared to self-assured individuals, repressors differ in the way they respond to self-relevant versus health-relevant scales.  相似文献

This paper examines refugee students' experiences in the Austrian mainstream school system. It highlights four areas: school connectedness, social exclusion, support systems and friendships. In the study, 55 refugee students between 8 and 21 years old enrolled in primary and secondary education participated in a semi-structured interview. Data were analysed with directed qualitative content analysis, whereby codes were created deductively and inductively. Students stressed the importance of schooling in order to prosper in the future, particularly through language acquisition. Peers and bilingual teachers played an important role in their efforts to learn German and develop feelings of belonging in the school system. While language acquisition was important for the students, they indicated that other support measures (i.e., remedial education) were largely absent. Further, half of the students reported bullying experiences (verbal, social and physical) associated with their refugee status, language proficiency and religious affiliation. This study has implications for school professionals. The scope of support refugee students receive at school must be broadened, forced migration should be addressed in school in order to counteract negative effects of bullying students receive due to their refugee status and school connectedness can be promoted by hiring staff from diverse cultural backgrounds.  相似文献
