Social exclusion is a risk factor for mental health problems. This study aims to identify the factors that contribute to social exclusion for children from several cultural backgrounds, living in low-socioeconomic status (SES) areas. Children from English, Chinese and Arabic speaking backgrounds participated in semi-structured interviews. They were asked questions around three prominent themes of social exclusion: exclusion from school, social activities and social networks. Children from English and Chinese speaking backgrounds experienced exclusion at school, from social activities or in social networks. The major barriers to social inclusion, which differed across cultural groups, included bullying, time constraints, economic resources and parental permission. Although money is a barrier to social inclusion, there are several other barriers that need to be considered, such as bullying, time and parental permission, and they may differ by culture. Mental health promotion programmes in schools and communities need to address these barriers in a culturally appropriate manner.

This paper reports findings from an ethnographic study of e-learning adopters in Turkey and examines ways in which cultural factors shape the adoption and use of information technology for online teaching. This research focuses on influential early adopters in the tertiary education sector in Turkey who have become change-agents by inspiring small networks of their peers. The study examines the operation of trust and inspiration in networking and teamwork in the Asian academic environment. The key findings of this research are that the early adopters become change agents in small groups and networks and that the process of adoption relies heavily on social networks and connections. Findings from this research can assist individuals and institutions to better understand ways in which to optimize the online teaching and learning experience for staff.

In her recent contribution to the British Educational Research Journal, Pauline McClenaghan identified the link between social capital and community development, particularly community development education, as a core area where scholarly and policy interests overlap. She concluded that the concept of social capital is unable to grapple with the complex social divisions that characterise contemporary Europe. The authors of this article question her account on three main grounds: the definition of social capital, which they hold is overly narrow, and does not deal with what Woolcock calls the ‘linking’ role of social networks; the presentation of the theoretical foundations of community development, which they believe is flawed in certain key respects; and a lack of clarity in the relationship between the research and the findings reported. The authors then present their own theoretically informed account of social capital as a means of understanding the role of community development, the challenges that it can face and the role of adult education for community development.

Purpose – The purpose of this paper is to suggest how enabling policy should be focused in a knowledge economy by developing the concept of a knowledge economy social network (KESN).

Design/methodology/approach – The paper employs an interdisciplinary approach in developing the KESN by drawing on concepts and methodology from economics, political science and social network theory.

Findings – The KESN's social capital is defined. As such, maintaining accountability, increasing cohesion and connections among knowledge actors are suggested as relevant guidelines for policy in the KESN.

Research limitations/implications – The knowledge economy should ideally be seen as having unique needs compared to the traditional economy in devising policy.

Practical implications – The paper suggests using the KESN as a basis for devising policy for a knowledge economy.

Originality/value – The paper uses an interdisciplinary approach to studying the knowledge economy and introduces the KESN.

By investigating differences in social networks among entrepreneurs in 20 cultures, this paper contributes to the debate on whether there is universality in the process of entrepreneurial networking. Representative samples of entrepreneurs were identified in the same manner in 20 countries from 2000 to 2004 (N=€‰304,560). The sampling methodologies and the questions asked were similar across all countries. Logistic regression was used to test for significant regional interaction effects involving personally knowing an entrepreneur. Results are contrary to the existence of any mono-dimensional form of networking practice but do strongly support the existence of both variform universality (culture moderates the importance of networking) and functional universality (cultural similarities in networking practice exist).

Background: Childhood mental health problems are prevalent in Australian children (14–20%). Social exclusion is a risk factor for mental health problems, whereas being socially included can have protective effects. This study aims to identify the barriers to social inclusion for children aged 9–12 years living in low socio-economic status (SES) areas, using both child-report and parent-report interviews.

Methods: Australian-born English-speaking parents and children aged 9–12 years were sampled from a low SES area to participate in semi-structured interviews. Parents and children were asked questions around three prominent themes of social exclusion; exclusion from school, social activities and social networks.

Results: Many children experienced social exclusion at school, from social activities or within social networks. Overall, nine key barriers to social inclusion were identified through parent and child interviews, such as inability to attend school camps and participate in school activities, bullying and being left out, time and transport constraints, financial constraints and safety and traffic concerns. Parents and children often identified different barriers.

Discussion: There are several barriers to social inclusion for children living in low SES communities, many of which can be used to facilitate mental health promotion programmes. Given that parents and children may report different barriers, it is important to seek both perspectives.

Conclusion: This study strengthens the evidence base for the investments and action required to bring about the conditions for social inclusion for children living in low SES communities.

Despite the applied importance of cohesion within organisational settings, researchers have yet to reach consensus about the dimensionality of group cohesion, and therefore appropriate tools for its measurement. The way that cohesion has generally been conceptualised has changed over time, but the measures appear not to reflect the underlying theory. This deficiency has impeded attempts to explore the relationship between co-worker cohesion and group performance (Beal et al., 2003; Mullen & Copper, 1994). Given inconsistent findings from previous factor analyses of cohesion, the present study employed exploratory means to help clarify the factor structure of cohesion within the workplace. Potential participants were recruited via the researchers' social networks. This snowballing technique led to 236 participants completing the online questionnaire. Exploratory factor analysis revealed four first-order factors of team commitment, friendliness, interpersonal conflict and communication that collectively accounted for 55.17% of the variance shared among the 75 cohesion items. Subsequently, a single higher-order factor was extracted which accounted for over half of the co-variation among the first order factors. This higher-order factor seems to reflect a general cohesion factor, as it was loaded by a diffuse collection of items, including those from the four lower-order factors as well as items that failed to load onto these lower-order factors. While there were similarities between these results and those of previous studies, the present factor structure did not map perfectly onto any of the existing conceptual models of cohesion. This finding highlights the need to incorporate some alternate factors that have previously been given little consideration.

In 2009, Deakin University and the Chinese University of Hong Kong trailed the use of Web 2.0 technologies to enhance learning outcomes in a third year architectural design studio that was modelled on the Virtual Design Studios (VDS) of past decades. The studio developed the VDS further by integrating a social learning environment into the blended learning experience. The Web 2.0 VDS utilised the social networking sites Ning.com, YouTube and Skype; various 3D modelling and video- and/or image-processing software; plus chat-software. These were used in combination to deliver lectures, communicate learning goals, disseminate learning resources, submit work, and provide feedback and comments on various design works in assessing students’ outcomes. This paper centres on issues of learning and teaching associated with the development of a Social Network VDS (SNVDS).

This paper presents results from a qualitative study of income support recipients with regard to how they feel about advertising which overtly appeals to their sense of fear, guilt and shame. The motivation of the study was to provide formative research for a social marketing campaign designed to increase compliance with income reporting requirements. This study shows that negative appeals with this group of people are more likely to invoke self-protection and inaction rather than an active response such as volunteering to comply. Social marketers need to consider the use fear, guilt and shame to gain voluntary compliance as the study suggests that there has been an overuse of these negative appeals. While more formative research is required, the future research direction aim would be to develop an instrument to measure the impact of shame on prosocial decision-making; particularly in the context of social networks rather than the wider society.

This paper addresses the problem of privacy-preserving data publishing for social network. Research on protecting the privacy of individuals and the confidentiality of data in social network has recently been receiving increasing attention. Privacy is an important issue when one wants to make use of data that involves individuals' sensitive information, especially in a time when data collection is becoming easier and sophisticated data mining techniques are becoming more efficient. In this paper, we discuss various privacy attack vectors on social networks. We present algorithms that sanitize data to make it safe for release while preserving useful information, and discuss ways of analyzing the sanitized data. This study provides a summary of the current state-of-the-art, based on which we expect to see advances in social networks data publishing for years to come.

Social network data has been increasingly made publicly available and analyzed in a wide spectrum of application domains. The practice of publishing social network data has brought privacy concerns to the front. Serious concerns on privacy protection in social networks have been raised in recent years. Realization of the promise of social networks data requires addressing these concerns. This paper considers the privacy disclosure in social network data publishing. In this paper, we present a systematic analysis of the various risks to privacy in publishing of social network data. We identify various attacks that can be used to reveal private information from social network data. This information is useful for developing practical countermeasures against the privacy attacks.

This study aimed to examine cross-sectional associations between neighbourhood social environmental factors and physical activity (PA) among Australian primary school children. Baseline data from a large-scale trial among 957 children (48% boys) aged 9–12 years were utilised. Children self-reported their perceptions of the neighbourhood social environment including social networks (e.g. there are lots of other children around to play with), and social capital (e.g. there are lots of people in my area I could go to if I need help). Children also self-reported their weekly walking frequency and PA from which average daily moderate to vigorous PA (MVPA) was calculated. Linear regression analyses examined these associations. Boys performed 17 min/day more MVPA than girls (p < 0.01), and girls performed one extra trip/week than boys (p < 0.001). Children’s perceptions of social capital (p < 0.0001) and social networks (p < 0.01) were both positively associated with MVPA and social capital was positively associated with walking frequency (p < 0.05). These associations were not moderated by the child’s sex. These findings suggest that children who had positive perceptions of neighbourhood social capital and social networks in the neighbourhood, tended to be more physically active. Longitudinal and experimental studies are required to further test the influence of these factors among children.
