We search for agent behavior rules which lead to the emergence of social networks that exhibit empirically observed phenomena: small-world property, scale-free degree distribution and stability in time. We assume that agents form and sever links using a cost-benefit analysis. Agents receive benefit from own links and from links that their friends form. On the other hand, link formation, deletion and keeping is costly. We find that a simple model structure which relies only on convex cost of link upkeep leads to stable networks which exhibit the small-world property.  相似文献

This study examined the contribution of family social network variables to recovery among Clubhouse members. A random sample of 118 members from one Clubhouse was recruited for this cross-sectional study. Among all respondents, greater overall family support and better relationship quality with the most supportive network member were correlated with greater levels of recovery. Clubhouse members perceived higher quantity and quality of support and more criticalness from their most supportive network members, principally family members, compared to the rest of their family members. Longitudinal studies are needed to further investigate the relationship between family support and recovery.  相似文献

Social network sites (SNSs) are organized around users who join an internet network to engage in daily discussions and postings. Though research informs us about SNSs usage, no published research addresses the use of social network sites among health science professionals. This study examined the relationship between social network usage, social support, and general well-being among undergraduate and graduate students. This study provides results that identify significant relationships (p < .001) associated with SNS usage and the variables of social support and general well-being among this study population. These results can inform the use of SNSs in university health sciences educational programs.  相似文献

Parents and adolescents (mean age, 15.7 years) from 177 adoptive families participating in the second wave of the Minnesota/Texas Adoption Research Project were interviewed about their post-adoption contact arrangements. The sample included families with no contact, stopped contact, contact without meetings, and contact with face-to-face meetings between the adolescent and birth mother. Openness arrangements were dynamic, and different openness arrangements were associated with different experiences and feelings. Adoptive families with contact reported having higher levels of satisfaction about their openness arrangements, experiencing more positive feelings about the birth mother, and possessing more factual and personal knowledge about the birth mother than did families without contact. Adolescents and adoptive mothers in the contact with meetings group reported the greatest satisfaction with their openness arrangements; those with no contact or stopped contact reported the least satisfaction with their arrangements. Participants having no contact were more likely to want the intensity of contact to increase in the future rather than stay the same. Many participants already having contact wanted it to increase in the future. Fewer than 1 percent of all participants wanted to see the intensity of contact decrease.  相似文献

This article explores the development and implementation of a Toronto-based incubator supporting local women in developing their own games. The incubator was created to help change the current (male-dominated) status quo of game production, promising participants skills sharing, support for the development of a new game, and entry into the local community of indie games developers. It was at the same time part of a large network of commercial and non-commercial interests with a shared agenda of promoting the local digital innovation scene. These different motivations and actors are considered to understand the nature of this complex social network market and the circulation of particularly feminized affective labour therein, detailing how value, reward, and benefit are conceptualized throughout this network. The article focuses on how and where these understandings are in alignment and where they fall apart, revealing problematic structures of power and control linked in particular to gender and entrepreneurialism in the area of digital innovation.  相似文献

This paper investigates the complex nature of access to the state for environmental movement organisations (EMOs) and adopts an interactionist approach to explore inter-organisational networking between EMOs and state actors. The paper supports existing evidence that proximate political opportunities are in part contingent on the interests, claims and frames of policy actors. The main theoretical contribution of this paper is to illustrate that EMOs strategically adapt to existing opportunity environments and actively seek to engage state actors that are most receptive to their demands, as opposed to those that have most influence in the domain, and that new modes of governance facilitate such access. Using evidence from forest activism in Indonesia shows that lobbying less powerful but more receptive actors is a strategy that EMOs use to overcome limited political opportunities and that semi-independent multi-actor forums expand access of EMOs to potential state actor allies. The paper also shows that within the Indonesian context, these multi-stakeholders forums are actively supported by international organisations which therefore directly contribute to expanding opportunities for EMOs.  相似文献

网络舆情的发展打破了传统话语权模式,创新了话语表达方式,促进了大学生话语权的实现。但在网络话语权实现过程中,大学生常表现出话语权利意识扭曲、话语自主性迷失、话语权行使非理性等问题。应该从鼓励与培育、对话与认同、定向与规制几个方面进行引导。  相似文献
