Information exchanges, debates, and negotiations through community social networks are essential to ensure the sustainability of the development process initiated in participatory research. The authors analyze the structural properties and robustness of a discussion network about mercury issues in a community in the Brazilian Amazon involved in a participatory research aimed at reducing exposure to the pollutant. Most of the villagers are connected in a large network and are separated from other individuals by few intermediaries. The structure of the discussion network displays resilience to the random elimination of villagers but shows vulnerability to the removal of one villager who has been a long-term collaborator of the project. Although the network exhibits a structure likely to favor an efficient flow of information, results show that specific actions should be taken to stimulate the emergence of a pool of opinion leaders and increase the redundancy of discussion channels.

NAFINSA was essential to Mexico’s development process. It served as the financial agent of the Federal Government and provided preferential access to long-term finance favouring selected business interests and groups. With the Washington Consensus, its tasks were reduced to correcting for market failures, becoming a complement to commercial banks, and focusing on attending the market segments falling outside the scope of commercial bank activity (notably SMEs). Although it appears as a successful story of institutional transformation, on closer inspection, NAFINSA has not been able to overcome key obstacles and its success in alleviating credit restrictions is very limited. NAFINSA must recover some of its functions, prerogatives, and responsibilities as a policy bank to become relevant in strengthening financial intermediation for capital formation.

Background: Relationships are vital to recovery however, there is uncertainty whether users have different types of social networks in different mental health settings and how these networks may impact on users’ wellbeing. Aims: To compare the social networks of people with long-term mental illness in the community with those of people in a general adult in-patient unit. Method: A sample of general adult in-patients with enduring mental health problems, aged between 18 and 65, was compared with a similar sample attending a general adult psychiatric clinic. A cross-sectional survey collected demographic data and information about participants’ social networks. Participants also completed the Short Warwick Edinburgh Mental Well-Being Scale to examine well-being and the Significant Others Scale to explore their social network support. Results: The study recruited 53 participants (25 living in the community and 28 current in-patients) with 339 named as important members of their social networks. Both groups recorded low numbers in their social networks though the community sample had a significantly greater number of social contacts (7.4 vs. 5.4), more monthly contacts with members of their network and significantly higher levels of social media use. The in-patient group reported greater levels of emotional and practical support from their network. Conclusions: People with serious and enduring mental health problems living in the community had a significantly greater number of people in their social network than those who were in-patients while the in-patient group reported greater levels of emotional and practical support from their network. Recommendations for future work have been made.

ABSTRACT We have carried out a set of Monte Carlo simulations to study a number of fundamental aspects of the dynamical evolution of multiple stellar populations in globular clusters with different initial masses, fractions of second generation (2G) stars, and structural properties. Our simulations explore and elucidate: (1) the role of early and long-term dynamical processes and stellar escape in the evolution of the fraction of 2G stars and the link between the evolution of the fraction of 2G stars and various dynamical parameters; (2) the link between the fraction of 2G stars inside the cluster and in the population of escaping stars during a cluster’s dynamical evolution; (3) the dynamics of the spatial mixing of the first-generation (1G) and 2G stars and the details of the structural properties of the two populations as they evolve toward mixing; (4) the implications of the initial differences between the spatial distribution of 1G and 2G stars for the evolution of the anisotropy in the velocity distribution and the expected radial profile of the 1G and 2G anisotropy for clusters at different stages of their dynamical history; and (5) the variation of the degree of energy equipartition of the 1G and the 2G populations as a function of the distance from the cluster’s centre and the cluster’s evolutionary phase.

In the context of an increasing clinical need to better support self-managemt for people living with long-term health conditions an interest in the role of social networks has emerged. Given that sport participation often provides opportunities for social engagement, a space to explore Self-managemt at the intersection of medical sociology and the sociology of sport has opened up. This article presents findings from an exploratory qualitative study with organ transplant recipients who have participated in Transplant Games events – national and international multi-sport competitions for organ transplant recipients. Our findings illustrate how sport-based Social networks serve as resources for health-related knowledge, provide participants with additional affective support and help shape health expectations for the future. Although sport-based Social networks were seen as an overwhelmingly positive resource for our participants, it is plausible that harmful unintended consequences could arise for patients with existing Self-managemt issues. As such, it is recommended that people seeking to use sport as a tool to enhance illness Self-managemt should consider the various and powerful ways that Social networks can be impactful and anticipate the potential consequences accordingly.

Analyzing the spread of information technologies on social consolidation the author pays special attention to the study of the Russian situation when the wide spreading of the new media does not result into intensive political consolidation. The author notes that Internet and social networks have an undeniable potential for social influence because of intensive social interaction of numerous stakeholders. At the same time, the nominal potential of social networks as a mechanism of political communication and consolidation is low today. Wide online access does not lead to an increase of the interest to politics or social activity, awareness or subjectivity. The themes of Internet communication is extremely diverse and, most importantly, is rarely focused on a practical result or a long-term plan of socio-political reform of public policy.

Abstract Sports development involves important aspects that collaborate towards the achievement of a high level sports performance. Parental support is one such fact to be considered in Long Term Athlete Development (LTAD), capable of benefiting or harming athletes if not adequately administered. This study registers and discusses the importance of parental support in female Artistic Gymnastics, from the perspective of Brazilian gymnasts who have participated in the Olympic Games. The method used was Oral History with the technique known as oral testimony. The participants of the study were the ten Brazilian gymnasts who represented Brazil in the Olympic Games from when the country first participated in this championship, in 1980, up to the best Brazilian classification in Athens (2004), totaling ten gymnasts (a sample comprising 100% or the research universe). Testimony analysis was conducted through crossanalysis. The study shows unanimity among the gymnasts in regards to the importance of parental support in the sports development process. In addition to reinforcing the results found in the literature, the testimonies provide details of the relationships between the gymnasts and their families for deeper reflections around the subject, a distinguishing feature of studies with oral testimonies.

This article introduces a new method to discover the role of influential people in online social networks and presents an algorithm that recognizes influential users to reach a target in the network, in order to provide a strategic advantage for organizations to direct the scope of their digital marketing strategies. Social links among friends play an important role in dictating their behavior in online social networks, these social links determine the flow of information in form of wall posts via shares, likes, re-tweets, mentions, etc., which determines the influence of a node. This article initially identities the correlated nodes in large data sets using customized divide-and-conquer algorithm and then measures the influence of each of these nodes using a linear function. Furthermore, the empirical results show that users who have the highest influence are those whose total number of friends are closer to the total number of friends of each node divided by the total number of nodes in the network.
