Rental Housing Assistance and Health: Evidence From the Survey of Income and Program Participation

Interest in the health impacts of renter housing assistance has grown in the wake of heated national discussions on health care and social welfare spending. Assistance may improve renters’ health by offering (a) low, fixed housing costs; (b) protection against eviction; and (c) access to better homes and neighborhoods. Using data from the Survey of Income and Program Participation and econometric analysis, I estimate the effect of receiving assistance from the public housing or Section 8 voucher programs on low-income renters’ reported health status and spending. Assisted renters spent less on health care over the year than unassisted low-income renters did, after controlling for other characteristics. This finding suggests that assisted housing leads to health benefits that may reduce low-income renters’ need to purchase health services. Voucher holders’ lower expenditures are influenced by their low, fixed housing costs, but public housing residents’ lower expenditures are not explained by existing theory.     

Measuring the Ambivalence of Religion: Introducing the Religion and Conflict in Developing Countries (RCDC) Dataset

Despite ample anecdotal evidence, previous research on violent conflict has found little evidence that religion is an important factor in organized violence. Quantitative work in this area has been largely confined to the interreligious character of conflict and measures of religious diversity, and has strongly neglected the peace aspect of religion. The Religion and Conflict in Developing Countries (RCDC) dataset helps to fill this gap with innovative and fine-grained data for 130 developing countries between 1990 and 2010. RCDC includes four types of religious violence (assaults on religious targets, attacks by religious actors, clashes between religious communities, and clashes with the state). In addition, RCDC contains data on interreligious networks and peace initiatives. This article demonstrates the usefulness of RCDC by applying our data to a preliminary analysis. The results indicate that interreligious networks are a reaction to identity overlaps and previous interreligious conflict.     

Application of mtDNA SNP analysis in forensic casework

In this study six forensic cases are presented where the routine analysis of samples for short tandem repeats (STRs) failed. The sequencing of the mitochondrial hypervariable region I (HVR I) also failed. Nevertheless, it was possible to analyse the samples with mitochondrial DNA (mtDNA) single nucleotide polymorphisms (SNPs) via SNaPshot technique. The age of the analysed samples ranged from 2 months to 1400 years. Saliva-, blood-, sperm-, hair-, tooth- and bone-samples were investigated. Furthermore the mtDNA SNP analysis of a forensic case sample showing a mixed stain profile is presented. It was possible to discriminate two different haplogroups in this mixed-person stain. If compared to another mtDNA SNP profile that was found in a hair, the discriminating SNPs of the hair were as well found in the mixed-person stain.To disburden the SNP analysis in forensic casework, haplogroup assignment criteria and quality criteria for mtDNA SNaPshot analysis are announced.     

The legal feasibility of an auto free zone in a metropolitan area

One of the suggested remedies for the extreme traffic congestion in the U.S. is the establishment of an auto free zone in downtown metropolitan areas. In order to determine the legal feasibility of such a plan, the authority of the states and municipalities to regulate public streets is reviewed. Special attention is given to eminent domain and the police power. The property rights of the affected persons are discussed. It is concluded that an auto free zone is legally feasible, but certain accompanying provisions would be prudent in order for the courts to uphold it. An annotated bibliography on auto free zones is included as an appendix.     

Bloodstain pattern analysis--casework experience

The morphology of bloodstain distribution patterns at the crime scene carries vital information for a reconstruction of the events. Contrary to experimental work, case reports where the reconstruction has been verified have rarely been published. This is the reason why a series of four illustrative cases is presented where bloodstain pattern analysis at the crime scene made a reconstruction of the events possible and where this reconstruction was later verified by a confession of the offender. The cases include various types of bloodstains such as contact and smear stains, drop stains, arterial blood spatter and splash stains from both impact and cast-off pattern. Problems frequently encountered in practical casework are addressed, such as unfavourable environmental conditions or combinations of different bloodstain patterns. It is also demonstrated that the analysis of bloodstain morphology can support individualisation of stains by directing the selection of a limited number of stains from a complex pattern for DNA analysis. The complexity of real situations suggests a step-by-step approach starting with a comprehensive view of the overall picture. This is followed by a differentiation and analysis of single bloodstain patterns and a search for informative details. It is ideal when the expert inspecting the crime scene has also performed the autopsy, but he definitely must have detailed knowledge of the injuries of the deceased/injured and of the possible mechanisms of production.     

Retrograde venous cerebral air embolism from disconnected central venous catheter: an experimental model

There are few reported cases of death attributed to retrograde cerebral air embolism from central venous catheter. The pathophysiological mechanism and the necessary conditions are not fully understood, also because of missing experimental data. We performed experimental simulation while working on a possible case of retrograde cerebral air embolism. A hermetic system consisting of two containers connected to each other and to an electric pump by means of rubber hoses was built. In this system, a fluid (water and blood) could continuously flow under conditions similar to those of the common jugular vein. The part of the system representing the jugular vein could be freely positioned at angles between 0 and 90°. A central venous catheter was inserted into this part. After disconnection, the behavior of the air bubbles entering the hose through the tip of the catheter was evaluated at different positions. At angles between 0 and 45°, the air bubbles followed the fluid flow. At angles >45°, the air bubbles showed the tendency to flow upstream; this phenomenon was more evident the more vertically the hose was located. We were able to demonstrate that a retrograde air embolism can be caused by a disconnected catheter and is even more likely if the neck is in a vertical position.     

Predictors of Physical Competence in Adolescent Girls

Physical competence, comprising athletic competence and physical appearance competence, is positively related to feelings of self-worth in adolescent girls. This study compared the relationships of psychological, physiological, and maturational constructs with perceived physical competence in adolescent girls. Perceived physical appearance and perceived athletic competence, peer acceptance, body weight, body mass index (BMI), aerobic fitness (VO₂max), physical activity level, and menarcheal status were assessed. Global self-worth was highly correlated with peer acceptance, perceived physical appearance, and perceived athletic competence in this sample. Regression analyses indicated that peer acceptance was the best predictor of perceived physical competence. Additional predictors of perceived physical appearance and athletic competence are discussed. Results suggest that postmenarcheal and larger girls may be at risk for low perceptions of physical competence. Enhancing competence feelings among adolescent girls may be accomplished by emphasizing friendship and social interaction within physical activity.     

Breaking the Double Impasse: Securing and Supporting Diverse Housing Tenures in the United States

What might be described as a double impasse characterizes debate on U.S. housing tenure with advocates fighting for rental or ownership housing on one side and Third Way or mixed-tenure solutions on the other. Breaking this impasse requires disengaging from conceptions of an idealized form of tenure and instead advocating making virtually all tenures as secure and supported as possible, so that diverse households are able to live in homes that best fit their changing needs over their life cycles. This essay (a) presents data on the variety of tenures in the United States; (b) conveys a new two-dimensional map of tenure according to their degrees of control and potential for wealth-building; and (c) shows how U.S. institutions shape their risks and subsidies. Most U.S. tenures are at least somewhat risky, including those that receive the greatest federal subsidies. A new housing system is needed to secure and support as many tenures as possible.
