Gene expression during blow fly development: improving the precision of age estimates in forensic entomology

Forensic entomologists use size and developmental stage to estimate blow fly age, and from those, a postmortem interval. Since such estimates are generally accurate but often lack precision, particularly in the older developmental stages, alternative aging methods would be advantageous. Presented here is a means of incorporating developmentally regulated gene expression levels into traditional stage and size data, with a goal of more precisely estimating developmental age of immature Lucilia sericata. Generalized additive models of development showed improved statistical support compared to models that did not include gene expression data, resulting in an increase in estimate precision, especially for postfeeding third instars and pupae. The models were then used to make blind estimates of development for 86 immature L. sericata raised on rat carcasses. Overall, inclusion of gene expression data resulted in increased precision in aging blow flies.     

Predicting overt and cyber stalking perpetration by male and female college students

In this study, self-report student surveys on early childhood maltreatment, attachment styles, alcohol expectancies, and narcissistic personality traits are examined to determine their influence on stalking behavior. Two subtypes of stalking were measured using Spitzberg and Cupach's (2008) Obsessive Relational Intrusion: cyber stalking (one scale) and overt stalking (comprised of all remaining scales). As t tests indicated that men and women differed significantly on several variables, OLS regression models were run separately for men (N = 807) and women (N = 934). Results indicated that childhood sexual maltreatment predicted both forms of stalking for men and women. For men, narcissistic vulnerability and its interaction with sexual abuse predicted stalking behavior (overt stalking R2 = 16% and cyber stalking R2 = 11%). For women, insecure attachment (for both types of stalking) and alcohol expectancies (for cyber stalking) predicted stalking behavior (overt stalking R2 = 4% and cyber stalking R2 = 9%). We discuss the methodological and policy implications of these findings.     

Youth alcohol use and dating abuse victimization and perpetration: a test of the relationships at the daily level in a sample of pediatric emergency department patients who use alcohol

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for women, ≥5 drinks per day for men), as compared with nonuse. Results: Approximately 52% of men and 61% of women participants reported experiencing DA victimization ≥1 times during the past 6 months, and 45% of men and 55% of women reported perpetrating DA ≥1 times. For both men and women, DA perpetration was more likely on a drinking day as opposed to a nondrinking day (ORs = 1.70 and ORs = 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a nondrinking day for both men and women (ORs = 1.23 and ORs = 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to nondrinking days (2.04 and 2.03 for men's and women's perpetration, respectively, and 1.41 and 1.43 for men's and women's victimization, respectively). Conclusions: This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration.     

A tax by any other name: The donor directed automatic percentage contribution bonus,a budget alternative for financing governmental support of charity

Our paper analyzes the merits of four alternatives for providing governmental support to charity—the existing tax write-off, a tax credit, a sliding matching grant, and a percentage contribution bonus. After searching for an appropriate budget mechanism (a five-year fixed-sum authorization and appropriation), we apply a wide-ranging set of criteria—equity, legitimacy, efficiency, reciprocity, controllability, etc.—to each of the four alternatives. In brief, the existing tax write-off is grossly inequitable among donors, poorly controlled by government, and is part of a tax system increasingly viewed as illegitimate by citizens. The advantages of the write-off are that it produces predictable amounts of income at low administrative cost without overtly raising questions of constitutionality. Its disadvantages would be mitigated by a tax credit in proportion to the amounts contributed by taxpayers. But the credit does not reach people who do not file returns and may significantly decrease income to charitable agencies. The sliding matching grant (under which the government pays to charity in proportion as the individual gives of his income) provides a particular form of equity for taxpayers but is deficient in other respects. The contribution bonus—a percentage of each dollar contributed paid to charity by government—is wholly equitable, includes all givers, sustains reciprocity with recipients, is controllable by government, and is legitimate in treating expenditures as expenditures and not as tax dodges. It also raises the possibility of increasing the government's contribution. The defects of the bonus are higher administrative costs and potential doubt about constitutionality. We conclude in favor of a percentage contribution bonus set high enough to provide marginally more income for charity and reduce financial uncertainties during the transition. Appraisal of political feasibility suggests that supporters of charity are likely to be worse off unless they come up with a more defensible approach, such as the contribution bonus. To help resolve doubts, we suggest adding on a small percentage contribution bonus to the present tax write-off for three years so as to test constitutionality and assess more precisely administrative costs. While there is no one proposal that will make everyone better off, the contribution bonus is far superior on most criteria to the alternatives.The paper was written for The Commission on Private Philanthropy and Public Needs.
