Humanitarian Interorganizational Information Exchange Network: How Do Clique Structures Impact Network Effectiveness?

Humanitarian information coordination and sharing continue to challenge the international community. Interorganizational networks are believed to be a way to improve coordination and collaboration among humanitarian organizations. Although researchers have devoted a considerable amount of time exploring the influence of network structure on network performance and effectiveness, little work has been done in the humanitarian relief field. We use the theoretical lens of social network to investigate the relationship between network cliques and network effectiveness. Data were collected through multiple sources among members of GlobalSympoNet, a community of humanitarian organizations engaged in humanitarian information management and exchange. Our findings suggest that, similar to the public health service delivery sector, network effectiveness can be explained by network integration and network cliques in the humanitarian relief field. We discuss these findings and provide some implications of our research in designing interorganizational networks within the humanitarian relief field.     

Symbolic Interactions and the Development of Women Leaders in Higher Education

The under‐representation of women in higher education (HE) leadership is a persistent global phenomenon. The purpose of this research is to re‐examine this issue through symbolic interactionism (SI). Eight women aspiring to leadership were invited to participate in semi‐structured interviews after attending a leadership programme specifically designed to enhance their leadership prospects. Analysis indicated ambiguities and contradictions that surround notions of leadership, in particular how the participants position themselves and are positioned in their workplace. This was evidenced by the meaning they attributed to: recognizing a leader; interactions with existing leadership; and speculation regarding their leadership capacity. Gendered notions were apparent in their constructed meanings. Similarity attraction was also evident, with men being observed as ‘paying it forward’, therefore facilitating promotion. Formal leadership training was advocated rather than experiential processes.     

Working With Parents of Gender-Variant Children: Using Social Action as an Emancipatory Research Framework

This article examines and reflects on the methodology used in a research project that involved group work activities with parents of gender-variant children. Gender variance in children remains a topic people talk little about. Discussions about people who express themselves differently from the social norms attached to their birth sex, to a large extent, remain rarely discussed. They challenge a society organized largely on the basis of a binary understanding of identity, one that belongs to either male or female. This article discusses the concept of oppression as being central to the experiences of gender-variant children and young people and their parents, and it proposes social action research as a compatible and appropriate research framework for exploring their experiences. We describe the research process, identify its achievements, and explore issues that had to be confronted. We suggest that traditional research structures may benefit from being revisited in order to allow emancipatory research to more fully achieve its potential for both research and social action.     

Pathophysiology of premenstrual syndrome and premenstrual dysphoric disorder

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder are triggered by hormonal events ensuing after ovulation. The symptoms can begin in the early, mid or late luteal phase and are not associated with defined concentrations of any specific gonadal or non-gonadal hormone. Although evidence for a hormonal abnormality has not been established, the symptoms of the premenstrual disorders are related to the production of progesterone by the ovary. The two best-studied and relevant neurotransmitter systems implicated in the genesis of the symptoms are the GABArgic and the serotonergic systems. Metabolites of progesterone formed by the corpus luteum of the ovary and in the brain bind to a neurosteroid-binding site on the membrane of the gamma-aminobutyric acid (GABA) receptor, changing its configuration, rendering it resistant to further activation and finally decreasing central GABA-mediated inhibition. By a similar mechanism, the progestogens in some hormonal contraceptives are also thought to adversely affect the GABAergic system. The lowering of serotonin can give rise to PMS-like symptoms and serotonergic functioning seems to be deficient by some methods of estimating serotonergic activity in the brain; agents that augment serotonin are efficacious and are as effective even if administered only in the luteal phase. However, similar to the affective disorders, PMS is ultimately not likely to be related to the dysregulation of individual neurotransmitters. Brain imaging studies have begun to shed light on the complex brain circuitry underlying affect and behaviour and may help to explicate the intricate neurophysiological foundation of the syndrome.     

Assessing social vulnerability and identifying spatial hotspots of flood risk to inform socially just flood management policy

This study presents the first nationwide spatial assessment of flood risk to identify social vulnerability and flood exposure hotspots that support policies aimed at protecting high-risk populations and geographical regions of Canada. The study used a national-scale flood hazard dataset (pluvial, fluvial, and coastal) to estimate a 1-in-100-year flood exposure of all residential properties across 5721 census tracts. Residential flood exposure data were spatially integrated with a census-based multidimensional social vulnerability index (SoVI) that included demographic, racial/ethnic, and socioeconomic indicators influencing vulnerability. Using Bivariate Local Indicators of Spatial Association (BiLISA) cluster maps, the study identified geographic concentration of flood risk hotspots where high vulnerability coincided with high flood exposure. The results revealed considerable spatial variations in tract-level social vulnerability and flood exposure. Flood risk hotspots belonged to 410 census tracts, 21 census metropolitan areas, and eight provinces comprising about 1.7 million of the total population and 51% of half-a-million residential properties in Canada. Results identify populations and the geographic regions near the core and dense urban areas predominantly occupying those hotspots. Recognizing priority locations is critically important for government interventions and risk mitigation initiatives considering socio-physical aspects of vulnerability to flooding. Findings reinforce a better understanding of geographic flood-disadvantaged neighborhoods across Canada, where interventions are required to target preparedness, response, and recovery resources that foster socially just flood management strategies.     

2011 MOBIUS Conference

The twelfth annual MOBIUS Conference was held June 7–9, 2011, at the Holiday Inn Executive Center in Columbia, Missouri. The MOBIUS consortium of Missouri is currently composed of fifty-nine academic libraries, two public libraries, and the Missouri State Library. The conference offered various opportunities, including a keynote address by Meredith Farkas and a networking dessert session on the first night. The second day featured six concurrent sessions, each having six different presentations, along with delicious food, generous door prizes, and the chance to meet with vendors. The third day consisted of four different four-hour post-conference training sessions. Presentations are available for download from the conference Web site.¹     

Mixture modelling as an exploratory framework for genotype-trait associations

We propose a mixture modelling framework for both identifying and exploring the nature of genotype-trait associations. This framework extends the classical mixed effects modelling approach for this setting by incorporating a Gaussian mixture distribution for random genotype effects. The primary advantages of this paradigm over existing approaches include that the mixture modelling framework addresses the degrees-of-freedom challenge that is inherent in application of the usual fixed effects analysis of covariance, relaxes the restrictive single normal distribution assumption of the classical mixed effects models and offers an exploratory framework for discovery of underlying structure across multiple genetic loci. An application to data arising from a study of antiretroviral-associated dyslipidaemia in human immunodeficiency virus infection is presented. Extensive simulations studies are also implemented to investigate the performance of this approach.     

Developing a Model of Community Wellbeing and Resilience in Response to Change

This study examines the relationship between base of the pyramid (BoP) entrepreneurship success and wellbeing. The major contention is that the success of the BoP entrepreneurs is influenced by information and training support provided by large private organizations. A total of 134 BoP entrepreneurs, who run community information centres in remote areas of Bangladesh with the support of a leading private telecommunications company, participated in this research. The result revealed that support from a large private organization is important to ensure business success, and that this subsequently enhances the wellbeing of BoP entrepreneurs. Not only has this study empirically confirmed that assistance provided by large private organizations to BoP entrepreneurs influences business success, assistance also enhances the wellbeing of this vulnerable group and thus facilitate to reduce poverty within the local community. This study therefore can be a guideline for large private organizations that are willing to carry out pragmatic corporate social initiatives.     

Accounting for the permanent vs temporary wage gaps among young adults: Three European countries in perspective

This article analyses wage differentials between permanent and temporary workers in the 25–40 age bracket using the 2010 European Union Statistics on Income and Living Conditions (EU‐SILC) wave data for France, Germany and Italy. Applying a Recentered Influence Function (RIF) regression and a reweighting estimation technique, we investigate the contribution of personal and job characteristics to wage differentials across the wage distribution. Results point to a large unexplained component of the wage gap across the whole distribution in Italy, while this component is weaker in France among highly paid employees and insignificant in Germany. These findings highlight potential policy considerations and areas for future research.     

The Role of the Environment in Sedentary Behavior in Community-Dwelling Older Adults

To compare amounts of sedentary behavior and physical activity in adults residing in planned group residential settings to those residing in private homes, this study recruited 31 older adults who resided in planned group residential settings (n = 13) and in private homes (n = 18). Daily activities were measured using the SenseWear Armband for 7 days. Estimates of the duration of daily activities performed across sedentary, light, and moderate-to-vigorous intensities were captured. It was found that participants in planned group residential settings were older (age 85.9 ± 3.5 vs. 78.3 ± 7.2; p = 0.001) and spent more time in sedentary behaviors (12.7 ± 1.5 vs. 11.3 ± 1.6; p = 0.02) than participants in private homes. The difference was attenuated slightly after controlling for age and wear time (adjusted difference 1.2 ± 0.6 hours, p = 0.06). Thus, adults residing in planned group residential settings, which provide supportive services, were more sedentary than adults residing in private homes. The environment in which older adults live may contribute to sedentary behavior.
