t is one of important topics in social network research how to form member clustering according to potential social relations by automatic context-aware the user's behavior feature. This paper presents a context-aware mobile P2P social network framework, member clustering model and algorithm. The user's location information, environmental characteristics etc. are introduced to the clustering algorithm, which intelligently cluster to potential P2P social network. The experimental results show that the proposed approach and the algorithm have a higher response speed, load balance and adaptive ability.

Mobile P2p

As social networking services, social network covers all the networking service form which regards human social as the core, obtains user behavior feature by situational awareness and finds potential social relations. By analyzing the application and system structure of context-aware technology, this paper proposed a mobile P2P social network system based on LTE network and its Algorithm and realized the structure of the mobile P2P social network system based on context-aware.

In this article, I examine from a comparative perspective how the experience of pregnancy is affected by pregnant women's social network, in an urban context. In particular, I analyse the role played by husbands or male partners, family, friends and medical specialists during gestation and how these relationships impinge on women's subjectivity. I contrast the earlier studies of Maria Isabel Almeida and Tania Salem, carried out in the 1980s, with my own research material, gathered in 2008, all of which dealt with middle class women living in Rio de Janeiro, Brazil, who were going through their first gestation. I argue, with this comparison, that different ways of thinking and living these relationships as well as the changes undergone in gender roles in the family affects women´s subjectivity, in particular the value given to the expression of individuality - its motivations, desires and emotions.

This study was conducted in a probabilistic sam- ple of 2,055 elderly in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, to examine components of social network (conjugal status and visits by the children, other relatives, and friends) and social support (satisfaction with personal relations and having persons on whom to rely) associated with limitations in performing basic activities of daily living (ADL). Multivariate analysis used the Hurdle model. Performance of ADL showed independent and statistically significant associations with social network (fewer meetings with friends and not having children) and personal support (dissatisfaction/indifference towards personal relations). These associations remained after adjusting for social and demographic characteristics, health status, and other indicators of social relations. Our results emphasize the need for greater attention to social network and social support for elderly with functional limitations and those with weak social networks and social support.

Analysis Of The Images

Background: Social networks have changed the dynamics of society in communication, commercial and social relations, advertising, among others. In sports, this would not be different. Along with this, the new media open up new possibilities for exploration of the image of the athlete, since traditional media conduct different treatments for male and female athletes. Objective: To verify the posts made on Instagram by Brazilian athletes and to verify if there are differences related to the gender of the athletes in the contents posted. Methods: The subjects selected for this research were Brazilian athletes and medalists of the 2012 Summer Olympics. The data were obtained through the collection of the images that the athletes posted on the Instagram and after that, the analysis of the images were made with the use of a checklist created for that study. Results: The results indicated that male and female did not present differences between categories of posted images. The most common type of images posted are the images in which the athlete is present, in places related to their work and in moments of relaxation. It also highlights the fact that most of the images posted do not make any reference to the sponsorships of the athletes. Conclusion: Therefore, it can be concluded that male and female have the same behavior of photo posting on social networks. It is also observed that the potential of social networks for advertising is still little explored by Brazilian athletes. Due to the originality of this work and because it seems to be a very pertinent theme in the present day, it is suggested the extension of this study.

Objective: Only 16% of people aged >65 years engage in recommended levels of physical activity, putting a vast major­ity at risk for multiple chronic conditions including heart disease. Physical activity is even lower among older adults with fewer economic resources. Research is needed to develop context-specific approaches to pair with physical activity interventions to increase effectiveness. In this pilot study, we examine social ties and physical activity levels of older adults living in a US Depart­ment of Housing and Urban Development subsidized senior housing community to test feasibility of a social network-based approach to physical activity interventions. This study is grounded in Social Contagion Theory and the Convoy Model of Social Relations, which argue health and health-related behaviors are facilitated through network ties.Methods: Data were collected through face-to-face interviews conducted over the course of three months (September- November 2018) with 46 residents living in a low-income senior housing community in southeast Michigan. Residents were asked about physical activity, people they know in the community, and their close social network composition.Results: Residents reported knowing, on average, six other residents and approxi­mately 28% of those in their close networks were also residents. Sociocentric network analysis identified two socially engaged (known by seven or more other residents) physically active residents, whereas ego-centric analysis identified four (60% or more of their network comprised residents).Conclusions: This study demonstrates potential feasibility of a strategic partnership that involves pairing social resources with physical activity interventions in afford­able senior housing. Multiple approaches, which need to be evaluated, exist to identify socially engaged residents.Ethn Dis. 2019;29(Suppl 1): 201-208; doi:10.18865/ ed.29.S1.201.

This study integrates the concept of context-awareness with association algorithms and social media to establish the Context-aware and Social Recommendation System (CASRS). The Simple RSSI Indoor Localization Module (SRILM) locates the user position; integrating SRILM with Apriori Recommendation Module (ARM) provides effective recommended product information. The Social Media Recommendation Module (SMRM) connects to users social relations, so that the effectiveness for users to gain product information is greatly enhanced. This study develops the system based on actual context.
