Effects of obesity on talar micro- and macro-morphology

The addition of information regarding obesity status to the forensic anthropological biological profile could significantly contribute to the identification of human skeletal remains since over 40% of the U.S. adult population is currently obese. This study examines the differences in talar shape and trabecular bone structure between obese and non-obese individuals. A sample of 20 obese and 20 non-obese divided evenly by sex was selected from the Texas State University Donated Skeletal Collection. Tali were imaged using x-ray computed tomography (voxel size: 28–38.7 μm). Image stacks were processed to produce binary images as well as trabecular thickness and spacing maps. Landmark-based geometric morphometric analyses were conducted to quantify shape variation. Shape coordinates were used to locate 100 geometrically homologous volumes of interest within each talus. Bone volume fraction, trabecular thickness, and trabecular spacing were extracted at each volume of interest. Within each sex, a one-way ANCOVA was used to determine if significant differences exist between obese and non-obese individuals in trabecular bone after controlling for age. The size of the talus as well as subtle aspects of shape were found to distinguish the sexes. The results further indicate that bone volume fraction significantly differs between obese and non-obese males. In females, bone volume fraction is correlated with age but does not differ between obese and non-obese. The study demonstrates that bone microstructure is a promising approach to estimating body mass or body mass index category but age effects diminish the potential for the talus to be used alone.     

Components of the Solution-Based Casework Child Welfare Practice Model That Predict Positive Child Outcomes

While a number of studies have shown the efficacy of the solution-based casework (SBC) practice model for child welfare (e.g., Antle, Christensen, van Zyl, & Barbee, 2012 Antle, B. F., Christensen, D. N., van Zyl, M. A. & Barbee, A. P. (2012). The impact of the Solution Based Casework (SBC) practice model on federal outcomes in public child welfare. Child Abuse & Neglect, 36, 342–353.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), the current analysis examines the top ranked behaviors in cases reaching outcomes of safety, permanency, and well-being in both high adherence and low adherence cases. Sixteen top behaviors seem to have the greatest impact on outcomes, all of which are key to the three major theoretical orientations utilized in SBC. Thus, these results not only narrow in on the key behaviors that drive success in the practice model, but also shows the utility of the theoretical underpinnings of the practice model.     

Entrepreneurial universities in two European regions: a case study comparison

An entrepreneurial university is a natural incubator that tries to provide a supportive environment in which the university community can explore, evaluate and exploit ideas that could be transformed into social and economic entrepreneurial initiatives. Entrepreneurial universities are involved in partnerships, networks and other relationships to generate an umbrella for interaction, collaboration and co-operation. Rapid developments in science, the multidisciplinary nature of frontier research, legislative changes such as the Bayh–Dole Act and demands from business and society have shaped knowledge-based entrepreneurship within universities. Despite sharing similar historical backgrounds, economic conditions and cultural and social structures, entrepreneurial universities in most countries remain distinct from one another by their institutional arrangements, traditions and characteristics unique to each organization. Interestingly, no comparative research has been conducted to understand the similarities and differences of the conditioning factors and the outcomes/outputs of entrepreneurial universities in different regions that share similar social, economic and political conditions. This paper addresses this research deficit, adopting institutional economics and resource-based view. We compare entrepreneurial universities in two European regions (Spain and Ireland) using an in-depth qualitative approach based on multiple case studies (two Spanish universities and two Irish universities) between 2006 and 2010. The findings provide organizational practices and approaches relevant to the transformation process of other regional universities seeking to become entrepreneurial.     

Own-age bias in video lineups: a comparison between children and adults

Abstract

The present study investigated whether child (six–eight years of age) and adult witnesses (18–29 years of age) would exhibit an own-age bias when trying to identify targets from video lineups. One hundred and eighty-six participants viewed two filmed events that were identical, except one starred a child target and one a young adult. After a delay of two–three days each witness saw a lineup for the child and adult target. Children exhibited an own-age bias and were better at correctly identifying the own-age target from a target-present (TP) lineup and made more correct rejections for the own-age target-absent (TA) lineup. Adults however, showed a reversed own-age bias for the TP lineups as they made more correct identifications for the child target, but exhibited no bias for the TA lineups. The results suggest that differences in identification accuracy may be due to whether witness age and suspect age overlap.     

Capital Offenders in Texas Prisons: Rates, Correlates, and an Actuarial Analysis of Violent Misconduct

This study analyzed the records of 136 recently incarcerated capital murder offenders in the initial phase (M = 2.37 years, range = 6-40 months) of their life sentences in the Texas Department of Criminal Justice. Prevalence rates of institutional violence were inversely related to severity: potentially violent misconduct (36.8%), assaultive violations (14%), serious assaults (5.1%), and homicides (0%). Consistent with prior studies, factors correlated with assaultive misconduct included age (inversely), prior prison confinement, and concurrent robbery or burglary in the capital offense. A simplified Burgess scale entitled the Risk Assessment Scale for Prison-Capital (RASP-Cap) was moderately successful in identifying varying levels of improbability of committing violence-related misconduct however defined (AUC = .715-.766).     

Taking Nonprofit Intermediaries Seriously: A Middle‐Range Theory for Implementation Research

The federal government often works through nonprofit intermediaries to reach and empower communities in the United States. One increasingly popular policy strategy is to offer grant funding to intermediary organizations in an effort to strengthen communities. Funded intermediaries are tasked with building the capacity of faith‐based and community organizations at the local level, but the policy theory that informs these programs does not specify how these capacity‐building efforts will lead to stronger communities. Missing is a middle‐range implementation theory that links inputs to community‐level changes through the actions of an intermediary. Derived from empirical case study evidence using process‐tracing analysis, the theory of the community‐integrated intermediary posited in this article helps fill that gap.
