TrueAllele® Genotype Identification on DNA Mixtures Containing up to Five Unknown Contributors

Computer methods have been developed for mathematically interpreting mixed and low‐template DNA. The genotype modeling approach computationally separates out the contributors to a mixture, with uncertainty represented through probability. Comparison of inferred genotypes calculates a likelihood ratio (LR), which measures identification information. This study statistically examined the genotype modeling performance of Cybergenetics TrueAllele^® computer system. High‐ and low‐template DNA mixtures of known randomized composition containing 2, 3, 4, and 5 contributors were tested. Sensitivity, specificity, and reproducibility were established through LR quantification in each of these eight groups. Covariance analysis found LR behavior to be relatively invariant to DNA amount or contributor number. Analysis of variance found that consistent solutions were produced, once a sufficient number of contributors were considered. This study demonstrates the reliability of TrueAllele interpretation on complex DNA mixtures of representative casework composition. The results can help predict an information outcome for a DNA mixture analysis.     

Investigating the Potential of Fluorescent Fingerprint Powders as a Marker for Blow Fly Larvae (Diptera: Calliphoridae)

Four fluorescent fingerprint powders (RedWop^?, GreenWop^?, Basic Yellow^?, and Yellow Powder^?) were evaluated as a marker for blow fly larvae. Administration methods included ingestion (high vs. low concentration) or topical. Ingestion of high concentrations of Basic Yellow^? and RedWop^? caused higher larval mortality. Basic Yellow^? delayed development and adult emergence while RedWop^? and Yellow Powder^? had a significant effect on particular stages of development, however, emergence time was not altered. Optimal administration is through ingestion at low concentration levels (<10%) or topically, with GreenWop^? demonstrating minimal adverse effects. Optimum wavelength for discrimination between powders was 450 nm. This research can aid in investigative training to increase visibility of larval and pupal blow flies. It can also be used in entomological studies to differentiate between larval blow flies (or other dipteran) species or individuals to further understand complex interactions and behavior during larval development.     

The Democratic Contribution of Political Market Researchers

Although we know that candidates, parties and governments conduct political market research and engage in heated debate about it, market research in politics remains a largely hidden activity. This article presents the perspectives of practitioners involved in collecting and using market research including advisors to 11 presidents and prime ministers and demonstrates that market analysis in politics is a multi‐varied activity, carried out within a complex context. The over‐simplistic criticism that political marketing means politicians simply follow focus groups needs to be revised, and although poor practice will always occur, practitioners are developing more fluid and mature ways to utilize research in politics. Political market research can play a valuable role in informing the decisions politicians make and enhance the relationship between the government and the public.

Qualitative Differences Among Rural and Urban Intimate Violence Victimization Experiences and Consequences: A Pilot Study

Relatively little is known about rural women's intimate violence experiences in comparison to urban women's experiences, partly because of the difficulty in accessing rural women. This pilot study used a protective order sample of 23 women (15 urban and 8 rural), which provides an access point that is relatively similar for comparisons across rural and urban areas. The number of participants is low and, therefore, results are preliminary. However, several significant findings emerged. Rural women reported significantly less social support, less education, less income, more physical abuse in the preceding year, more childhood physical and sexual abuse, and worse overall health and mental health, as well as encountering abuse earlier in the relationship. Both groups reported higher rates of illegal drug and cigarette use than those among the general population. The findings highlight some overall important themes in examining rural and urban intimate violence victims by suggesting that rural and urban intimate violence victims have different victimization experiences and service needs. Implications for further research and intervention are discussed.     

The Tobin Tax: Another lost opportunity?

The United Nations Development Programme (UNDP) has promoted the so-called `Tobin Tax' as a major mechanism for generating a substantial increase in global resources for tackling human-development priorities. Such a levy, on largely speculative and unproductive international transactions, may be capable of generating over US$300 billion per year: several times higher than existing levels of bilateral aid. However, given the muted dialogue at the 1995 World Summit for Social Development, and in order to secure the necessary support of leading developed countries and global financial institutions, it may be inevitable that the Tobin Tax, if adopted, would ultimately serve the interests of the wealthier economies. There is, therefore, an urgent need for the development sector to engage in debate about how, and how much of, such funds would be directed to priority human-development purposes.     

Female murderers in a southern city, 1975–1992

A study of a population of 36 females arrested for homicide in a southern, nonurban city from 1975 to 1992 was conducted using both qualitative and quantitative data. The study explored the demographic, social, legal, and offense characteristics of female homicide offenders as well as events leading to the murder. The profile of female homicide offenders in a southern, non-urban setting that emerged from this study is supportive of earlier studies focusing on female homicide offenders in large urban areas.     

Strain,Negative Emotions,and Deviant Coping Among African Americans: A Test of General Strain Theory

Although previous research on Agnew's (1992) general strain theory (GST) tends to yield significant effects of strain on negative emotions as well as deviance and crime, results tend to be mixed with regard to (1) the effects of negative emotions on deviance and crime and (2) conditioning factors that Agnew suggests affect the selection of coping strategies. To address these issues, we test hypotheses, derived from GST, about the relationships among strain, negative emotions, and deviant coping by analyzing data from a nationally representative sample of African American adults. Ordinary least squares regression results generally support our hypotheses. First, fully mediating the effects of strain on deviant coping, negative emotions have consistently significant effects on deviance, regardless of whether we use composite or separate measures of inner- and outer-directed emotions and deviance. Interestingly, as hypothesized, the same-directed effects of negative emotions on deviant coping are larger than the opposite-directed ones. Second, while self-esteem and self-efficacy as conditioning factors generally fail to receive empirical support, religiosity is found to significantly buffer the effects of negative emotions on deviance. Implications of our findings for further development of GST are discussed.
