Knowledge Sharing Among Tourists via Social Media: A Comparison Between Facebook and TripAdvisor
2016
This paper examines tourists' knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision) and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. An online survey is conducted with 1200 Spanish consumers. Based on the full sample, our structural equation modeling supports most of the hypothesized paths, while trust does not affect either social in…
Forecasting Changes in Religiosity and Existential Security with an Agent-Based Model
2018
We employ existing data sets and agent-based modeling to forecast changes in religiosity and existential security among a collective of individuals over time. Existential security reflects the extent of economic, socioeconomic and human development provided by society. Our model includes agents in social networks interacting with one another based on the education level of the agents, the religious practices of the agents, and each agent's existential security within their natural and social environments. The data used to inform the values and relationships among these variables is based on rigorous statistical analysis of the International Social Survey Programme Religion Module (ISSP) and…
A magically nice guy: Parasocial relationships with Harry Potter across different cultures
2011
This study explored parasocial relationships (PSRs) with Harry Potter that readers from different cultures have developed. An overall sample of 2551 Potter fans from Germany (individualistic culture) and Mexico (collectivistic culture) completed an online questionnaire assessing their parasocial relationship with the character. Fans from the collectivistic culture rated Potter’s sociability higher than fans from the individualistic culture. For fans from both cultures, social attraction turned out as most important determinant of PSRs with Potter, while homophily ranked lowest. Overall, PSRs and fandom turned out to be quite similar across cultures, with some differences in character perce…
Fuzzy Concepts in Small Worlds and the Identification of Leaders in Social Networks
2014
In the study of the Social Networks, the Small World phenomenon appears frequently. We apply some techniques of graph theory and fuzzy sets to characterize the Small World features as well as the existence of the figure of leader in Social Networks. These techniques help to the conceptual formalization in relational networks analysis, by transforming linguistic and human-focused manner concepts related to social networks in some formal representation. These techniques are also applied when the similarity among nodes wants to be measured in order to study the current homophily present in a Network.
No road is long with good company. What factors affect Ph.D. student’s satisfaction with their supervisor?
2021
PurposeHow frequently may be advisable for a supervisor to meet a PhD student? Are PhD students more satisfied if supervised by someone of the same gender, nationality or with common research interests? Thus far, we lack quantitative evidence regarding similar crucial aspects of managing PhD supervision. The goal of this study is hence to investigate what factors affect Ph.D. students' satisfaction about the professional and personal relationships with their supervisors.Design/methodology/approachWe focus on the characteristics of the interactions between the student and the supervisor, controlling for other important factors, namely, the supervisor's and student's traits, and the character…
Inspired by Friends: Adolescents' Network Homophily Moderates the Relationship between Social Comparison, Envy, and Inspiration on Instagram
2019
© Copyright 2019, Mary Ann Liebert, Inc. Research on the negative psycho-emotional implications of social comparisons on social network sites such as Instagram has rapidly accumulated in recent years. However, little research has considered the extent to which such comparisons can elicit positive motivational outcomes for adolescent users, specifically inspiration. Furthermore, little is known about whether it matters whom young people compare themselves to on Instagram (i.e., network composition) and how this may modulate the emotional outcomes of Instagram social comparisons. The present study thus sought to determine how adolescents' Instagram comparisons of ability associate with inspir…
Bifurcations in business profitability: An agent-based simulation of homophily in self-financing groups
2021
Abstract Formal financial institutions inadequately distribute startup capital to business ventures of ethnic minorities, women, low-educated, and young people. Self-financing groups fill this gap because in these associations agents accumulate their savings into a fund that is later used to provide loans to the members. This study builds and simulates an agent-based model that compares the profitability of businesses started by members of self-financing groups against businesses financed by commercial loans. The results indicate that—besides the self-generation of debt capital—businesses of members of self-financing groups can have higher returns due to the consolidation of social capital …
How individual characteristics shape the structure of social networks
2015
Abstract We study how students’ social networks emerge by documenting systematic patterns in the process of friendship formation of incoming students; these students all start out in a new environment and thus jointly create a new social network. As a specific novelty, we consider cooperativeness, time and risk preferences – elicited experimentally – together with factors like socioeconomic and personality characteristics. We find a number of robust predictors of link formation and of the position within the social network (local and global network centrality). In particular, cooperativeness has a complex association with link formation. We also find evidence for homophily along several dim…
Determinants and consequences of auditor dyad formation at the top level of audit teams
2021
Abstract This study investigates the determinants and consequences of forming dyads at the top level of audit teams, i.e., dyads between concurring and lead auditor. We apply the sociological theory of homophily, i.e., the implicit preference for similar others, to hierarchically structured auditor dyads. Our regression analyses reveal that sharing the same gender and the same ethnicity, measured by dialect, increases the likelihood of dyad formation beyond what one would expect based on the characteristics of the pool of available auditors. Further, we observe that forming auditor dyads sharing the same age is avoided, suggesting that the need to establish a legitimate hierarchical relatio…
Analysis of Users Behaviour from a Movie Preferences Perspective
2018
Despite their tremendous popularity, Online Social Networks (OSNs) have several issues related to the privacy of social users. These issues have motivated researchers to develop OSN services that take advantage of the decentralized platforms (such as P2P systems or opportunistic networks). Decentralized Online Social Networks (DOSNs) need specific approaches to manage the decentralization of social data. In particular, data availability is one of the main issues and current proposals exploit properties of the social relationships to manage it. At the best of our knowledge, there are no proposals which exploit similarity between users, expressed with the term homophily. Homophily has been we…
