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.     

Development and Validation of the Post-Dissolution Relational Communication Index

Relational dissolution is a distressing life event. Dissolution is further complicated when communication between ex-partners is inefficient, unpredictable, and strained. This examination uncovers the aspects of postdissolutional communication in a 2-part study. In Study 1, 271 participants experiencing a breakup completed surveys regarding their communication with an ex-romantic partner. The study empirically operationalizes these behaviors in the Post-Dissolution Relational Communication Index and reports on the factor structure, reliability, and convergent validity of the 2-factor solution produced. Both factors were significantly correlated with participants’ reports of communication satisfaction with a former relationship partner and the perceived seriousness of the relationship. In Study 2, self-reports from 151 participants who had experienced a divorce provided support for its use with divorced couples. A third factor was identified illustrating differences between nonmarital and marital ex-partners. Implications for postdissolution relationships and satisfaction with former partners are addressed. Furthermore, suggestions for practice are discussed.     

Folate: a possible role in erectile dysfunction?

A growing body of evidence suggests a role for homocysteine (Hcys) and folate (FA) in erectile function (EF): Hcys appears to impair EF affecting endothelium via several mechanism whereas the role of FA remains to be elucidated, besides decreasing Hcys. To assess correlation between erectile dysfunction (ED) and serum levels of FA, Hcys, and B12, we enrolled 31 patients affected by ED (Group A; age 52.83?±?11.89 years) and 31 healthy adults (Group B; age 49.14?±?13.63 years). Fasting blood samples were taken for each subject. ED was assessed by the International Index of Erectile Function-5 (IIEF-5). IIEF-5 mean score was significantly lower in Group A than in Group B (10.71?±?4.24 versus 23.32?±?1.33, p?p?p?相似文献   

Implications of parents’ work travel on youth adjustment

Guided by ecological, work–family spillover and crossover frameworks, this study examined mechanisms linking parental work travel (i.e. nights per year) to youth adjustment (i.e. externalizing and internalizing behaviours) through youth’s perceptions of parenting (i.e. knowledge, solicitation) with traveller and youth gender as moderators in a sample of 78 children in 44 two-parent families residing in the United States. The findings from multilevel analyses suggested that mothers’ travel nights predicted lower levels of maternal knowledge, with variation by traveller and youth gender. Mothers’ and fathers’ work travel and perceived parenting were predictors of youth’s externalizing behaviours, whereas only fathers’ work travel and perceived parenting were predictors of youth’s internalizing behaviours. Tests of indirect effects indicated that maternal work travel linked to youth’s externalizing behaviours through youth’s perceptions of maternal knowledge. These findings add to our limited understanding of work–family issues for parents who have the unique work demand of frequently travelling.     

The perfect lawn: exploring neighborhood socio-cultural drivers for insect pollinator habitat

In the United States, residential yards are typically overlooked for biodiversity conservation, yet they account for a significant portion of urban green space. Yard vegetation can serve as valuable habitat patches for insect pollinator populations in cities, providing important foraging and nesting resources. Based on long-term native bee sampling data, we investigate the social and cultural drivers shaping front yard vegetation composition and configuration at two study sites with consistently low native bee species diversity and abundance. We employ quantitative remote sensing approaches with analysis of qualitative interview data to examine residential vegetation patterns and analyze the socio-cultural relationships between people and vegetation. Data analyses reveal both study sites have lower levels of vegetation composition and complexity, resulting in reduced habitat resources. We find neighborhood public-facing landscaping is shaped by various socio-cultural influences: aesthetics, norms, reference-group behavior, institutions, socioeconomics, and identity. Front yard land-use and decision-making practices are particularly meaning laden, as these spaces are often perceived as visible representations of longstanding neighborhood identity and contiguous common areas to be managed to a “perfect lawn” ideal. The quantitative and qualitative data are used to characterize the two study sites and inform future urban conservation and development efforts salient to citizen stakeholders.
