Social games in a social network.

We study an evolutionary version of the Prisoner's Dilemma game, played by agents placed in a small-world network. Agents are able to change their strategy, imitating that of the most successful neighbor. We observe that different topologies, ranging from regular lattices to random graphs, produce a variety of emergent behaviors. This is a contribution towards the study of social phenomena and transitions governed by the topology of the community.

From social integration to health: Durkheim in the new millennium.

It is widely recognized that social relationships and affiliation have powerful effects on physical and mental health. When investigators write about the impact of social relationships on health, many terms are used loosely and interchangeably including social networks, social ties and social integration. The aim of this paper is to clarify these terms using a single framework. We discuss: (1) theoretical orientations from diverse disciplines which we believe are fundamental to advancing research in this area; (2) a set of definitions accompanied by major assessment tools; and (3) an overarching model which integrates multilevel phenomena. Theoretical orientations that we draw upon were developed by Durkheim whose work on social integration and suicide are seminal and John Bowlby, a psychiatrist who developed attachment theory in relation to child development and contemporary social network theorists. We present a conceptual model of how social networks impact health. We envision a cascading causal process beginning with the macro-social to psychobiological processes that are dynamically linked together to form the processes by which social integration effects health. We start by embedding social networks in a larger social and cultural context in which upstream forces are seen to condition network structure. Serious consideration of the larger macro-social context in which networks form and are sustained has been lacking in all but a small number of studies and is almost completely absent in studies of social network influences on health. We then move downstream to understand the influences network structure and function have on social and interpersonal behavior. We argue that networks operate at the behavioral level through four primary pathways: (1) provision of social support; (2) social influence; (3) on social engagement and attachment; and (4) access to resources and material goods.

[Biosocial relations as contact points in the social network. A contribution to the theoretical discussion in psychosomatic medicine].

Psychosomatic medicine needs a theoretical model for clinical tasks and for research. To start from Freud's psychoanalytic theory (conversion and anxiety neurosis) and Alexander's model of the "vegative neurosis" a system theory concept of the bio-psychosocial model (Lipowski) is presented and discussed critically. Instead of further investigation on the problem of "unity", or on monistic or dualistic views of the mind-body problem, we propose a new theoretical approach. If we focus our interest on nodal points of the bio-psychosocial network we can learn more about somatic-psychosocial interaction and can develop practical consequences for research and clinical issues.

Decomposing the relationships between pretreatment social network characteristics and alcohol treatment outcome.

OBJECTIVE: In Project MATCH a summary measure of network support for drinking identified matching and prognostic effects. The goals of the present analyses were (1) to determine which of the 11 component indexes are most predictive of treatment outcome regardless of treatment type and (2) to determine which of the indexes are most influential in the already demonstrated network support by treatment interaction effect. METHOD: This is a secondary data analysis of the outpatient arm of Project MATCH (N = 952), focusing primarily on the Important People and Activities instrument administered pretreatment. RESULTS: Patients with larger daily networks and patients with more abstainers/recovering alcoholics in their networks had a better prognosis. Patients with a higher network drinking frequency did better in Twelve Step Facilitation than in Motivational Enhancement Therapy. CONCLUSIONS: Three of the 11 indexes can be used to replicate the prognostic and matching effects found for an overall index of network support. These may be measured by a short form of the Important People and Activities instrument.

Social networks, structural interdependence, and marital quality over the transition to marriage: a prospective analysis.

This study examined the relationship between couples' network interdependence and marital quality in a sample of 347 couples that were recruited at the time of their first marriage. Husbands and wives completed separate, self-administered questionnaires at home. Analyses are based on data collected at the time of marriage, at the first anniversary, and at the second anniversary. Results indicated that after marriage, husbands' and wives' friend and family networks became increasingly interdependent. Moreover, the interdependence of the friend and family networks at marriage predicted wives' marital quality at the first anniversary, whereas wives' marital quality at the first anniversary predicted the interdependence of the friend network at the second anniversary. No significant longitudinal relations were observed for husbands.

Competent jerks, lovable fools, and the formation of social networks.

When looking for help with a task at work, people turn to those best able to do the job. Right? Wrong. New research shows that work partners tend to be chosen not for ability but for likability. Drawing from their study encompassing 10,000 work relationships in five organizations, the authors have classified work partners into four archetypes: the competent jerk, who knows a lot but is unpleasant; the lovable fool, who doesn't know much but is a delight; the lovable star, who's both smart and likable; and the incompetent jerk, who.. .well, that's self-explanatory. Of course, everybody wants to work with the lovable star, and nobody wants to work with the incompetent jerk. More interesting is that people prefer the lovable fool over the competent jerk. That has big implications for every organization, as both of these types often represent missed opportunities. Because they are liked by a disproportionate number of people, lovable fools can bridge gaps between diverse groups that might not otherwise interact. But their networking skills are often developed at the expense of job performance, which can make these employees underappreciated and vulnerable to downsizing. To get the most out of them, managers need to protect them and put them in positions that don't waste their bridge-building talents. As for the competent jerks, too often their expertise goes untapped by people who just can't put up with them. But many can be socialized through coaching or by being made accountable for bad behavior. Others may need to display their competence in more isolated settings. Intriguingly, managers aren't limited to leveraging people that others like and changing those that others loathe. They also can create situations in which people are more apt to like one another, whatever their individual qualities.

Promoting organ donation and transplantation among South Asians in the United Kingdom: the role of social networks in the South Asian community.

The percentage of South Asians on the kidney transplant waiting list in the United Kingdom is 3 times their percentage in the general population. Obviously, organ donation and transplantation among South Asians in the United Kingdom needs improvement. In recent years, ethnically targeted campaigns in the mass media have specifically attempted to attract donors from the South Asian communities. A number of pilot studies have been done to evaluate the effectiveness of these initiatives in providing information about organ donation to South Asians. Results indicate that detailed information related to transplantation was learned mainly by people within the community receiving transplants and was transmitted through various informal community networks rather than through the resources provided by the Department of Health. This article provides an overview of who South Asians are and how these community networks were established. Transplant professionals must devise effective strategies to access these community networks, thereby raising the consciousness of transplantation among South Asians in the United Kingdom.

Sexual health promotion in Chennai, India: key role of communication among social networks.

Communication about sex and sexual health is an important facilitator in gaining accurate knowledge about prevention of sexually transmitted diseases (STDs) and promotion of sexual health. Understanding how and with whom communication about sex occurs and the nature of the information exchanged is valuable in designing sexual risk prevention interventions. In this study of low-income communities residents in Chennai, India, our aim was to understand the composition of personal communication networks, the nature of information related to sex and sexual health that is exchanged in these networks and the value of communication among members of these networks. We conducted in-depth open-ended interviews using a structured interview guide with 43 individuals. We also conducted 12 focus group discussions. Individuals were selected using snowball sampling. Our results indicate that information about sex and sexual health is exchanged within and between four groups: married women, married men, unmarried men and unmarried women. Communication leads to an expansion of sexual networks among unmarried men and treatment seeking behaviour for STDs in all groups. Unmarried men offer immense potential for intervention given the range of topics related to sex and sexual health that are discussed and the risky sexual behaviours practiced. Spousal communication about sexual behaviour or sexual health is minimal and shifting norms for prevention would be difficult. Interventions identifying communication networks and influencing the natural communication patterns in these networks may be a viable HIV prevention strategy in the study area.
