This longitudinal investigation examined main and interactive effects of coparent support and conflict on mother and child adjustment in 248 low-income, African American, single mother-headed families. The findings indicated that coparent conflict was a more robust predictor of mother and child maladjustment both cross-sectionally and longitudinally than was coparent support. Moreover, findings revealed that coparent conflict and support interacted to predict one parenting behavior, monitoring, both cross-sectionally and longitudinally. Coparent relationships characterized by high levels of support and low levels of conflict were associated with the highest levels of parental monitoring behavior, whereas coparent relationships characterized by low levels of support and high levels of conflict were associated with the lowest levels of monitoring. The findings highlight the importance of examining both positive and negative aspects of coparent relationships in this at-risk, but understudied, group. 相似文献

Studies have demonstrated that women with a history of childhood sexual abuse (CSA) are at increased risk of revictimization,
but research has not yet examined whether a history of CSA may affect patterns of remaining in or returning to abusive relationships
in adulthood. This study examines the impact of a CSA history on decisions to return to abusive relationships in a sample
of 104 adult domestic violence survivors. Participants were interviewed about the number of times that they had previously
separated from and returned to their abusive partner, the factors that influenced their decision to return (both psychological/internal
and environmental/external factors), and their perceived likelihood of returning in the future. As predicted, CSA survivors
(n = 34) reported a significantly greater number of past separations than non-CSA survivors (n = 70). CSA survivors were also significantly more likely to report that their decisions to return were influenced by emotional
attachment to the batterer. CSA survivors did not perceive themselves to be at greater risk of returning in the future, suggesting
that they may be more likely to underestimate their vulnerability to returning to the battering relationship. Clinical implications
of the findings are discussed. 相似文献

In 1968, a child's cranium was recovered from the banks of a northern Canadian river and held in a trust until the "cold case" was reopened in 2005. The cranium underwent reanalysis at the Centre for Forensic Research, Simon Fraser University, using recently developed anthropological analysis, "bomb-pulse" radiocarbon analysis, and forensic DNA techniques. Craniometrics, skeletal ossification, and dental formation indicated an age-at-death of 4.4 ± 1 year. Radiocarbon analysis of enamel from two teeth indicated a year of birth between 1958 and 1962. Forensic DNA analysis indicated the child was a male, and the obtained mitochondrial profile matched a living maternal relative to the presumed missing child. These multidisciplinary analyses resulted in a legal identification 41 years after the discovery of the remains, highlighting the enormous potential of combining radiocarbon analysis with anthropological and mtDNA analyses in producing confident personal identifications for forensic cold cases dating to within the last 60 years. 相似文献

A growing literature suggests that communication strategies can promote or inhibit intimate partner violence (IPV). Research on communication is still needed on a group ripe for early IPV intervention: high school-aged adolescents. This article revisits our previous analyses of young female reproductive clinic patients (Messinger, Davidson, & Rickert, 2011) by examining how the adolescent and young adult respondents differ. To explore replicability of the adolescent results across populations, they are compared to 487 adolescent female students sampled from four urban high schools. Across samples, all communication strategies were used more frequently within violent relationships. Multivariate analysis identified escalating strategies used and received as being positively associated with physical violence used and received in all three samples. Regarding verbal reasoning and temporary conflict avoidance, substantial differences appeared between the young adult and adolescent clinic samples, and results from the adolescent clinic sample were largely replicated with the adolescent school sample, suggesting that young adult samples in this literature are not adequate proxies for adolescents. 相似文献

We examined whether training in both the verbal and nonverbal indicators of truth telling and lying would have positive effects on Law Enforcement Officers’ (LEOs) ability to evaluate truths from lies. College course-level training on empirically validated verbal and nonverbal indicators of truth telling and lying was provided to mid- to advanced-career level LEOs, whose accuracy in detecting lies from truths was assessed pre- and post-training using truthful and deceptive videos of mock crimes and opinions. A marginally significant truth bias existed at pre-test; training, however, resulted in a significant improvement in accuracy rates for both truth and lie videos, and the truth bias that existed at pre-test was eliminated. Additional analyses indicated that accuracy rates improved for videos of mock crimes but not for opinions. These findings add to a small but growing literature that indicates that training on validated verbal and nonverbal indicators of truth telling and lying has positive benefits. 相似文献

Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures. 相似文献

This study used a modified version of the Conflict Tactic Scale (Straus, 1990) to measure the expression of verbal and physical aggression among 572 college students (395 females and 177 males) involved in dating relationships over the previous year. Results indicated that 82% (n = 465) of the total sample reported having engaged in verbally aggressive behavior with a dating partner over the past year, whereas 21% (n = 116) admitted to acting in a physically aggressive manner over the same interval. No significant gender-based difference was found for verbal aggression scores; however, females were significantly more likely to report using physical force than were male students. Male and female students who used verbal aggression were characteristically similar to each. Both had experienced aggression from a parent as children and had drunk alcohol within 3 hours (before or after) an argument with a dating partner. Male and female students who admitted using physical force were dissimilar except that both had experienced parent-child aggression. For male students, having witnessed conjugal violence and their general drinking patterns were also significantly related to their using physical force, whereas for females, the use of physical force was associated with drinking alcohol within 3 hours of an argument with a dating partner. 相似文献

How diversified are small town revenues? Revenue diversification is analyzed among towns governed by town meetings. Using previously developed diversification measures, the findings confirm that these localities draw from less diverse revenue streams than other state and local governments. The reasons for these variations include differences in home rule status as well as tax and expenditure limitations imposed by states. The authors suggest that revenue allocation in these jurisdictions is substantively different from other forms of local government because these communities rely much less on sales taxation than states and municipalities. Their essay proposes possible options for improvement, along with other criteria by which small towns can assess their revenue diversification. 相似文献

This research is motivated by a change in Florida that affected assisted living facilities (ALFs) by removing the property tax exemptions for those operated by nonprofit organizations. As such, this paper addresses two research questions: (1) Are there systematic differences between Florida's for-profit- and nonprofit-designated ALFs in terms of operations and service provision? (2) What was the impact, if any, of losing and regaining their property tax exemptions on the operations of Florida's nonprofit ALFs? We use data from the Florida Agency for Health Care Administration to conduct difference of means testing for-profit versus nonprofit ALFs, as well as annual financial data of each ALF property owners' IRS Form 990 from the National Center for Charitable Statistics Core Files and parcel-level property data from the state of Florida to conduct regression analysis using three different dependent variables measuring various components of nonprofit ALF operations. We find that nonprofit ALFs have greater legitimacy in service delivery than for-profits, as nonprofit ALFs have higher service capacity, quality, and variety than for-profit ALFs in Florida. In addition, property tax exemptions for nonprofit ALFs in Florida decrease total expenses and increase officer compensation. 相似文献
