Network closure's impact on firms’ competitive advantage: The mediating roles of knowledge processes

This study draws on the knowledge management and social network disciplines to examine the effect of network closure on organizations’ competitive advantage. We hypothesize that the level of network closure affects an organization's capability of knowledge identification, knowledge transfer, knowledge protection and knowledge institutionalization; these capabilities in turn affect an organization's competitive advantage. Thus, we model network closure as indirectly affecting an organization's competitive advantage. A Partial Least Square (PLS) analysis of the survey data of 78 Chinese petrochemical firms shows that network closure can both enhance and decrease an organization's competitive advantage. Network closure enhances an organization's competitive advantage by facilitating knowledge protection and transfer (via institutionalization), but decreases competitive advantage by hindering knowledge identification. Environmental dynamics that the organizations encounter are observed to moderate the effect of network closure. Combining our results with the findings from the literature, we propose that organizations operating in a dynamic environment, where the domain knowledge is in a state of flux, need to place great importance on knowledge identification; such organizations should choose a sparse network that allows them to receive diverse knowledge. In contrast, organizations operating in a stable environment should opt for a dense network to protect their knowledge and facilitate transfer of required knowledge.     

Experiences of Younger Siblings of Young Men in Prison

Whilst the detrimental effects of forced separation through incarceration have been explored in the context of parent–child relationships, little is known about the social and psychological impact of having a sibling in custody. The present research was carried out in order to develop a better understanding of the needs and experiences of children who have a sibling in prison and is based on an interpretative phenomenological analysis of the accounts of eight young people (age 9–17, mean = 13 years) with an older brother in custody. The interviews revealed a series of themes, including the emotional response to a sibling being taken into custody, a reluctance to disclose information to teachers and peers, and perceptions of own behaviour in the light of the sibling's experiences of the criminal justice system. Findings are discussed in relation to policy implications and recommendations for those working with young people, and suggestions are made for future research directions.     

Information systems and occupational stress: a theoretical framework

The information systems (IS) profession is a stressful profession. However, there is little theoretical or empirical research on the effects of occupational stress on IS professionals. A major reason is because IS professionals and researchers are unaware of the consequences of occupational stress and unfamiliar with the occupational stress literature. The purpose of this paper is to propose a theoretical framework of occupational stress for IS professionals. Based on a review of the IS, psychology, and general management literature, 12 occupational stress models are identified. These stress models are analyzed along the two dimensions of focus and theoretical foundation. The analysis shows that most of the occupational stress models consider stress to be the consequence of the interaction between an environmental stimulus and the idiosyncratic response of the individual. Further analysis of these models suggests that nine key points are critical in developing a theoretical framework of occupational stress for IS professionals. A mapping of how the existing stress models incorporate the nine key points is also presented. The findings of this paper can provide a theoretical basis for further research on the occupational stress of IS professionals. Finally, an agenda for further research into this issue is presented.     

Creating pathways to participation: a community-based developmental prevention project in Australia

Pathways to Prevention is a developmental prevention project focused on the transition to school in a disadvantaged multicultural urban area in Queensland. The project incorporates two elements: The Preschool Intervention Program (PIP) promotes communication and social skills related to school success; and the Family Independence Program (FIP) (parent training, facilitated playgroups, support groups, etc) promotes family capacity to foster child development. Using a quasi-experimental design (N= 597), improvements in boys' but not girls' behaviours over the preschool year were found. FIP reached more than a quarter of the target population, including many difficult-to-reach families experiencing high stress. Case studies and other qualitative data suggest positive outcomes.     

‘The Anarchists' World Cup’: Respectable Protest and Media Panics

In 2005 225,000 people marched through Edinburgh enjoining the G8 to ‘Make Poverty History’. The coalition's own assessment of their campaign highlighted the importance of media by focusing on the extent of media coverage. Media outlets, however, have their own agendas. Detailed analysis of newspaper coverage preceding the G8 Summit suggests a disjuncture between campaign objectives and media frames. This paper explores how far newspaper accounts of G8-related protests were ‘framed’ in terms of social movement aims, and how far in terms of anticipated violence. Our findings lead us to caution against an uncritical equation of ‘coverage’ and ‘success’, offering a more nuanced account of the interplay between social movements and media.     

Cultivating Interest and Competency in Gerontological Social Work: Opportunities for Undergraduate Education

Undergraduate social work programs are well-positioned to recruit students to gerontology, but little is known about how well curricular activities help foster students' commitment to the field. This study considers whether a small group of undergraduate students' interactions with older adults positively impacts students' plans to work with older adults; perceptions of skills; and feelings of comfort and competency in working with older adults. Experiences from this study suggest that experiential learning can positively impact students' perceptions of work with older adults, but may not be enough to draw students to the field. Implications for undergraduate education are discussed.     

Testing Set-Point Theory in a Swiss National Sample: Reaction and Adaptation to Major Life Events

Set-point theory posits that individuals react to the experience of major life events, but quickly adapt back to pre-event baseline levels of subjective well-being in the years following the event. A large, nationally representative panel study of Swiss households was used to examine set-point theory by investigating the extent of adaptation following the experience of marriage, childbirth, widowhood, unemployment, and disability. Our results demonstrate that major life events are associated with marked changes in life satisfaction and, for some events (e.g., marriage, disability), these changes are relatively long lasting even when accounting for normative, age related changes.
