Substance use among African American adolescents in the Midwest

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed.     

A Validation Study of the Langley et al. (2017) Decision Tree Model for Sex Estimation

Langley et al. (2017) developed a sex estimation decision tree utilizing two traditional cranial traits (glabella and mastoid) and a new trait: zygomatic extension. This study aimed to test the reliability of their zygomatic extension scoring method and validate their sex estimation method. Ordinal score data were collected from 281 male and female U.S. White and Black individuals. The five traditional cranial traits were collected from physical specimens, while zygomatic extension was scored from 3D cranial models. Intra‐ and interobserver analyses carried out on a subsample of 30 individuals indicate good agreement between zygomatic scores. The decision tree correctly sexed 71.5% of the sample, but a strong sex bias (94.2% correct for females, 49.3% correct for males) severely limits the utility of this method. The Walker (2008) and Stevenson et al. (2009) methods produced higher accuracy rates (80.8% and 82.6%, respectively), although these methods also produced sex and ancestry biases.     

Sperm elution: An improved two phase recovery method for sexual assault samples

This report describes the validation of a two phase cell recovery technique for the elution of two common cell types, epithelia and spermatozoa, from frequently examined items submitted as part of sexual assault casework. Furthermore, separation of cell types prior to microscopic examination of cell pellets improves the scientist's confidence in observing and scoring spermatozoa that may be present. During the validation, Orchid Cellmark's Sperm Elution© method consistently recovered a greater number of spermatozoa from simulated sexual assault items and swabs taken following consensual sexual intercourse compared to a water extraction technique. On average the Sperm Elution method recovered over twice the number of spermatozoa compared to the water method. The ability to separate the cell types present allows a rapid microscope slide search for spermatozoa and faster DNA extraction protocol in comparison to Cellmark's previous preferential method.     

Comparison of methods for visualizing blood on dark surfaces

Difficulties can arise when screening dark casework items for blood, a poor contrast between blood and the background can mean stains are not always evident. Typical indirect searching methods can be time consuming and may result in potentially important bloodstains being missed. Luminol, fluorescein, hydrogen peroxide, ultraviolet light and infrared photography were tested in an effort to find a rapid and efficient blood search tool for direct application to dark surfaces. Methods were compared in their sensitivity, specificity, ability to work on various surface types and their effect on DNA extraction and typing. Along with experimental results, the ease of use, costs and the health and safety considerations were also compared. Hydrogen peroxide was determined to be the most effective method. However, where blood was likely to be dilute, luminol was proposed due its greater sensitivity.     

Sentencing in child sexual assault cases: factors influencing judicial decision-making

Abstract

To date, there has been limited examination of variables that influence sentencing in child sexual abuse cases. This study examines the extent to which offence characteristics (such as the number of offences, number and age of victims), the behaviour and perceived credibility of the victim impact upon both sentence length and the setting of earliest parole dates. Analyses conducted using data from 66 adjudicated cases of child sexual assault from the County Court of Victoria, Australia revealed that longer sentences were handed down to offenders who had perpetrated multiple offences, or who had committed offences against younger children. Lower levels of victim credibility were associated with shorter sentences and earlier parole dates for offenders, which were also associated with the presence of more harmful behavioural indicators of abuse. The findings are discussed regarding the importance of presenting evidence about the behaviour of victims following sexual abuse in criminal trials.     

The Projection of Development: Cinematic Representation as A(nother) Source of Authoritative Knowledge?

Popular representations of development need to be taken seriously (though not uncritically) as sources of authoritative knowledge, not least because this is how most people in the global North (and elsewhere) ‘encounter’ development issues. To this end, and building on the broader agenda presented in a previous article exploring the usefulness of literary representations of development, we consider three different types of cinematic representations of development: films providing uniquely instructive insights, those unhelpfully eliding and simplifying complex processes, and those that, with the benefit of historical hindsight, usefully convey a sense of the prevailing assumptions that guided and interpreted the efficacy of development-related interventions at a particular time and place. We argue that the commercial and technical imperatives governing the production of contemporary films, and ‘popular’ films in particular, generate a highly variable capacity to ‘accurately’ render key issues in development, and thereby heighten their potential to both illuminate and obscure those issues.     

Fair Trade-Organic Coffee Cooperatives,Migration, and Secondary Schooling in Southern Mexico

We explore three trends in rural southern Mexico (Fair Trade coffee, migration, and conditional cash transfers) that could explain the rapid rise in education from 1995–2005 using survey data from 845 coffee farming households in Oaxaca and Chiapas, Mexico. Results from a household fixed-effects model show that household participation in a Fair Trade-organic cooperative contributed to about a 0.7 year increase in schooling for girls. US migration opportunities appear to have even stronger positive impacts on schooling for females. Although participation in Fair Trade-organic cooperatives appears also to have increased male schooling, increased migration opportunities have had an indeterminate effect for males.     

The Institutional Foundations of Inequality and Growth

After a decade of research, the effect of inequality on long-run economic growth remains unresolved, in part because researchers have treated omitted variable bias as an estimation problem rather than a deeper question of causality. In this article we argue that the key omitted variable is the quality of economic institutions. Using both cross-country and panel data specifications, we find no direct effect of inequality on growth in the long-run. Rather, the protection of property rights simultaneously raises growth rates and reduces income inequality. We interpret these findings as evidence that insecure property rights disproportionately disadvantage the poor.
