AbstractThis paper brings two major research lines in current sociology together. Research on social networks has long focused primarily on network effects but meanwhile also addresses the emergence and dynamics of networks. Research on trust in social and economic relations shows that networks have effects on trust. Using game theory, we provide a simple model that allows for an integrated and simultaneous analysis of network effects on trust and for the endogenous emergence of the network. The model also allows for characterizing the value of the network. We use standard assumptions on full strategic rationality. Testable implications of the model as well as model extensions are sketched.

Social Network Effects

Purpose Emergency managers face coordinative challenges that require a high degree of mobility, flexibility and the ability to interpret heterogeneous, location-dependent information of various sources and quality. Recent information and communication technology-driven developments like crowdsourcing or social networks have opened up new organizational possibilities for emergency managers. To make quick but solid decisions, and improve the coordination of activities performed by crowdsourcees during disaster response, the authors suggest the use of collaborative features from crowdsourcing and inherent availability of resources from social network effects. In this paper, the idea of considering collaboration and crowdsourcing as drivers for flexibility in the design of business processes in the context of emergency management is prepared, the meaning of location-dependent tasks for volunteers is investigated, and the added value of social network effects is substantiated. Design/methodology/approach This paper is part of an ongoing research project in the field of crowdsourcing. It represents conceptual work that builds on relevant literature. Findings In terms of emergency management, the paper sheds light on what emergency managers may consider when coordinating activities performed by volunteers and how they may benefit from social network effects. Furthermore, it is shown how they can exploit information using collaboration-based and tournament-like crowdsourcing, how they can benefit from invoking additional resources using weak ties from social networks, and how visualization of information may support decision-making. Practical implications Exemplary applications to exploit crowdsourcing and social network effects to support improvisation and to respond flexibly in disaster response are given. Originality/value This paper suggests novel collaborative approaches to support emergency managers in their decision-making. Based on social network analysis, the value of weak ties is elaborated, and based on a taxonomy from crowdsourcing, distinct collaborative alternatives are developed and proposed for application in emergency management.

Abstract Social isolation is an emerging phenomenon known to significantly influence health outcomes and carries specific risk in older age. As part of a larger study exploring the social network effects on health among persons age 65 and above, it was found that four cases from a larger sample (n=89) could not name any one from their social relationships supportive to them in managing their health while living with complex chronic health needs. In addressing these findings, these cases, bounded spatially by individual social networks and temporally by the time of the study interview, served the basis for intensive analysis using multiple data points from in-depth interviews and survey measures. Measures included descriptive data (social networks, demographics) and measures of health (SF-12), and social support (MOS-SSS). Each participant case identified as female gender and single, three lived alone, had a high burden of chronic conditions and poor health. All had recent hospitalizations (1 or more within the past year). The structures of their social networks varied in type of relationship roles and size. Social support was perceived overall as low. This study offers a specific contribution to research on social connection/isolation. This phenomenon is relative to specific contexts. Findings emphasize that social isolation can be specific to certain aspects of identity and poorer health in older age. Additional research on the functions and qualities of social networks, in addition to the structure, are important to specify in future research and knowledge development for practice assessment to determine social connection and isolation.

Using Data

This study examines the recent phenomenon of “cross-border marriage” in South Korea: foreign brides migrating into Korea to get married to Korean bachelors. Using data from the National Survey of Multicultural Families 2009, one of the biggest data sets on marriage migrants, we analyze how the difference in migrants’ initial methods of entry affects the level of their life satisfaction. The findings show greater life satisfaction for those who used personal social networks, when compared with those who used commercial brokers as a method of entry. The analyses also reveal the importance of current social networks and their role in moderating the effect of the initial methods of entry after a prolonged period of residence.

Although interest in internationalization of firms from the emerging economies is growing, research employing network theories has been limited. The article provides a systematic literature review on the internationalization of firms originating from the emerging economies, from a network perspective. The major finding is that, contrary to expectations, social networks do not play such an important role as in the case of developed market firms. To fill this gap and to advance a more nuanced view of the network effects, the paper generates hypothesis highlighting the positive impact of networks on the initiation of internationalization process, and negative impact of social networks on speed, foreign market diversity and internationalization performance.

Online professional social networks have become a noteworthy tool to help professionals create, strengthen, and maintain valuable business connections. However, the question remains as to who is actually using online professional social networks and how the diffusion of the social network has occurred. Looking at diffusion and usage through innovation diffusion theory, critical mass and a network effects lens, this paper seeks to examine the diffusion of an online professional social network (LinkedIn) for a specific population of university business schools. Using longitudinal analysis (2008 compared to 2011) our findings advocate network dynamics of homogeneous populations display consistent patterns of participation and non-participation. The authors’ findings suggest LinkedIn diffusion is not consistent across all business schools examined. A greater critical mass and network effect appears to have been achieved across larger research universities when compared to smaller university populations. An analysis of the results and future research directions are presented.

The Social

In this paper we interrelate different theories of identity and describe how various social contexts and cognitive motives influence the process of identity change. We consider two competing theories about the linkage of contexts with motives for identity change: the effect of category traits, based on social identity theory, and the effect of social networks, based on identity theory. To explore these relations, we use data collected on more than 6,000 adolescents at six high schools in two consecutive school years. Multilevel logit models reveal a strong relationship between contexts and perceived identity imbalances, and a strong effect of identity imbalance on identity change. More important than category traits are the social network characteristics of prominence, homogeneity, and bridging; these form social contexts that affect perceptions of identity imbalance, and the perceptions in turn lead to a heightened incidence of identity change.

Social Network Effects

The quality of romantic relationships and their associations with both partners' personality traits and social networks were studied in 100 younger couples. The similarity of partners was modest with respect to personality traits, and moderate to large with respect to the perceived quality of the partner relationship and their social networks. While similarity in personality was unrelated to relationship quality, dyadic analyses showed that one's perceived quality of relationship was better predicted by one's own personality (i.e. actor effects) than by the personality of one's partner (i.e. partner effects). Moreover, relationship quality could to some extent be predicted by the quality of the social network once the personality traits of each partner were controlled. Results are discussed from a transactional view of personality and relationships. Copyright © 2004 John Wiley & Sons, Ltd.
