Women's motives for violent and nonviolent behaviors in conflicts

Drawing from past research on women's motives for intimate partner violence (IPV) perpetration, correlates of women's perpetration, and correlates of nonviolent conflict, we created a scale containing 125 possible motives, representing 14 broad domains (e.g., self-defense, retaliation). Participants were an ethnically diverse sample of women who had perpetrated no physical IPV against their current partner (n = 243), threats but not physical IPV (n = 70), nonsevere physical IPV (n = 193), and at least one act of severe (e.g., choke) physical IPV (n = 93). An exploratory factor analysis yielded a seven-factor solution, representing Partners' Negative Behaviors, Increase Intimacy, Personal Problems, Retaliation, Childhood Experiences, Situation/Mood, and Partners' Personal Problems. Differences by women's IPV perpetration and race and/or ethnicity were tested with means representing these seven factors and a computed variable representing self-defense. Although motives differed by perpetration type, main effects for Partners' Negative Behavior, Personal Problems, Retaliation, and Childhood Experiences were modified by interactions, suggesting ethnicity should be considered when developing interventions.     

A blind trial evaluation of a crime scene methodology for deducing impact velocity and droplet size from circular bloodstains

In a previous study, mechanical engineering models were utilized to deduce impact velocity and droplet volume of circular bloodstains by measuring stain diameter and counting spines radiating from their outer edge. A blind trial study was subsequently undertaken to evaluate the accuracy of this technique, using an applied, crime scene methodology. Calculations from bloodstains produced on paper, drywall, and wood were used to derive surface-specific equations to predict 39 unknown mock crime scene bloodstains created over a range of impact velocities (2.2-5.7 m/sec) and droplet volumes (12-45 microL). Strong correlations were found between expected and observed results, with correlation coefficients ranging between 0.83 and 0.99. The 95% confidence limit associated with predictions of impact velocity and droplet volume was calculated for paper (0.28 m/sec, 1.7 microL), drywall (0.37 m/sec, 1.7 microL), and wood (0.65 m/sec, 5.2 microL).     

Assessment of histomorphological features of the sternal end of the fourth rib for age estimation in Koreans

The aim of this study was to assess the histomorphological features of the fourth rib and to develop age-predicting equations for Koreans. Sixty-four rib samples (36 males and 28 females) obtained from forensic cases were used for developing equations. Two thin sections (<100-microm thick) per sample were prepared by manual grinding. Multivariate analysis of covariance revealed statistically significant differences in age-adjusted histomorphological variables between sexes. Using stepwise regression analysis, osteon population density and average osteon area were correlated with unknown sex (r2 = 0.826), and sex plus two histomorphological variables provided the best results for an age-predicting equation given the assumption of knowing the sex of a specimen (r2 = 0.839). Average Haversian canal area had little influence on age estimation for male or female samples, and relative cortical area was not significantly related to age for any specimen.     

Post-mortem cases involving amphetamine-based drugs in The Netherlands. Comparison with driving under the influence cases

In this study we reviewed the post-mortem cases in the years 1999-2004 that were presented at the Netherlands Forensic Institute. The concentrations of amphetamine-based drugs in femoral blood from cases of suspected unnatural death were compared with concentrations in whole blood from non-fatal cases of driving under the influence (DUI cases) and with literature. Furthermore, the combinations with other drugs and/or alcohol were investigated. Amphetamine-based drugs were present in 70 post-mortem cases and 467 DUI cases. The most detected amphetamine-based drug was MDMA, followed by amphetamine. The presence of MDA could usually be explained by metabolism of MDMA. Methamphetamine and MDEA were rarely present. Frequently, the amphetamine-based drugs were taken in combination with alcohol and/or other non-amphetamine-based drugs such as cocaine or cannabinoids. The 70 post-mortem cases were divided into 38 amphetamine-based drug caused (i.e. the amphetamine-based drug directly caused or contributed to the death) and 32 amphetamine-based drug related deaths (i.e. death was not directly caused by the amphetamine-based drug). In the latter category, other (poly)drug intoxications and death by violence or drowning were the most frequent causes of death. In 30 cases, MDMA caused death directly. The range in blood concentrations of MDMA in these cases was substantial, i.e. 0.41-84 mg/L with a median concentration of 3.7 mg/L (n=30). MDMA blood concentrations in the MDMA related deaths (n=20) and in the DUI cases (n=360) varied up to 3.7 and 4.0 mg/L, respectively. Seven victims died from the direct effects of amphetamine; the blood concentration of amphetamine ranged from 0.24 to 11.3 mg/L, with a median concentration of 1.7 mg/L (n=7). The median concentrations of amphetamine in the amphetamine related deaths (n=13) and the DUI cases (n=208) were much lower, i.e. 0.28 and 0.22 mg/L, respectively. Amphetamine blood concentrations up to 6.0 and 2.3 mg/L were seen in the drug related deaths and DUI cases, respectively. The most frequently encountered amphetamine-based drugs in the investigated deaths were MDMA and amphetamine. The majority of MDMA- and amphetamine-caused deaths, i.e. 90% of these deaths, occurred with blood concentrations above 1.5 and 0.80 mg/L, respectively. MDMA and amphetamine blood concentrations in drug related deaths and DUI cases, however, overlap the range of fatal concentrations. Therefore, MDMA or amphetamine concentrations should never be used alone to establish the cause of death.     

Use of sibling pairs to determine the familial searching efficiency of forensic databases

Pairs of individuals tested at the 13 CODIS core STR loci to determine sibship were used as a source of familial data that was seeded into a larger data set of 12,000 plus DNA profiles simulating a CODIS-like offender database. To determine whether known sibs could be found in the larger database two methods were used: degree of allele sharing and a kinship matching approach. The allele sharing method detected 62 of 109 of the known sib pairs (57%) while kinship matching detected 90 of the sib pairs (83%). Although kinship matching was the more efficient method of the two, the number of false positives generated prior to finding a true match was inversely related to the likelihood of sibship suggesting that many true siblings would not be easily found in a large forensic database via familial searching techniques.     

Performance Measurement in State Budgeting: Advancement and Backsliding from 1990 to 1995

Performance measurement has been one of the dominant themes of budget reform in the 1990s and has been prevalent in the mainstream of budgeting since the 1950s. Given the attention that performance measurement has had nationally, states might be expected to have made major strides in this arena in recent years. The article considers the current status of performance measurement practices, and identifies both advancement and backsliding made by states between 1990 and 1995. The discussion is based on data obtained from surveys of state budget offices in those two years. Indexes of performance measurement were constructed, and these became the bases of regression analyses using independent variables pertaining to state characteristics. Generally, these analyses were unsuccessful in explaining the variations among the states. The findings underscore the diversity among the states in their budgetary practices and the fact that budget reform, in the sense of increased use of performance measurement, is not necessarily achieved in a straight line of progression. The article considers possible explanations for the changes.     

Direct and Indirect Services for Children in Domestic Violence Shelters

The majority of women entering battered women’s shelters bring children with them and those children often require specialized programs that address the ways in which witnessing domestic violence has affected them. Several programs have been developed and implemented; however, few have been empirically evaluated. The current article critically examines several intervention strategies and their effectiveness. Barriers to service are also identified. Although there is a paucity of research in this area, the present review suggests that intervening with children may show promise for breaking the cycle of violence.     

Perceptions and Satisfaction with Father Involvement and Adolescent Mothers’ Postpartum Depressive Symptoms

This study examined the associations between adolescent mothers’ postpartum depressive symptoms and their perceptions of amount of father care giving and satisfaction with father involvement with the baby. The sample included 100 adolescent mothers (ages 13–19; mainly African-American and Latina) whose partners were recruited for a randomized study for fathers only. Controlling for prenatal depressive symptoms and other prenatal and postpartum variables, we found that higher levels of mothers’ satisfaction with father involvement rather than perception of amount of fathers’ care giving was significantly associated with fewer postpartum depressive symptoms. The relationship between satisfaction with father involvement and depressive symptoms was partially mediated by mothers’ sense of parenting competence and not by mothers’ parenting stress. Policy and programs should place greater emphasis on early support for adolescent mothers and their partners, particularly when mothers desire the involvement of the father with his child.
