Family member response to violent infant kidnapping

All family members interviewed suffered from chronic posttraumatic stress disorder 5 or more years after an infant kidnapping. Psychiatric nurses should routinely assess for secondary victimization related to any type of traumatic stressor. Nurses should refer parents and families to materials available from the National Center for Missing and Exploited Children (NCMEC) (http://www.missingkids.com/).     

Factors influencing middle and high schools' active parental consent return rates

The authors examined factors influencing the return rates for attempting to collect active parental consent forms from 21,123 students in the 7th through 10th grades in 41 middle and high schools. Overall return rates from middle schools were higher than from high schools. Schools that offered high levels of staff support for collecting consent forms had higher return rates. Procedures where the consent form was attached to a school form that parents had to complete and return to the school yielded the highest return rate. Implications for how researchers can obtain a high parent consent form return rate are discussed.     

Staff & client perceptions of unit quality: a pilot study

This pilot study compared psychiatric health care team members' perceptions of unit quality with discharged clients' perceptions of quality of care received on the unit. The staff members were from four different service units in one acute care psychiatric facility. The study used the Perceptions of Unit Quality (PUQ) scale, a valid and reliable outcome measurement instrument, developed by Cronenwett. Most quality assurance instruments that exist have focused on individual caregivers' or service-specific views of quality, but the PUQ scale allows quality assurance data that represent team performance to be described through team perceptions of quality. Results of this pilot study suggest that use of the PUQ scale, in conjunction with clients' perceptions of unit quality, may be a legitimate approach in continuous quality improvement efforts in psychiatric-mental health care centers.     

Child maltreatment in families experiencing domestic violence

This study examined the association between physical domestic violence (PDV) and reported child maltreatment in a cohort of children at risk for maltreatment. Participants were 219 6- to 7-year-old children and their caregivers. PDV was measured by combining caregivers' self-reports and children's reports, while child maltreatment was based on state Division of Social Services Central Registry records. Among 219 child-caregiver pairs studied, 42 (19.2%) had at least one maltreatment report in the 2 years following the interviews. PDV consistently predicted child maltreatment, with adjusted odds ratios ranging from 2.96 to 3.46. In addition, we investigated interactions between PDV and other predictors of child maltreatment. Among Aid to Families with Dependent Children (AFDC) participants, PDV was highly associated with child maltreatment. However, this pattern was not observed among subjects who did not have AFDC. There is an increased incidence of child maltreatment reports in families experiencing PDV. AFDC participation intensified the probability of child maltreatment in the presence of PDV. Findings also suggest that in households experiencing PDV, social supports may protect children from maltreatment.     

A study of the relationship between protective behaviors and drinking consequences among undergraduate college students

The authors identified the number, type, and frequency of protective behaviors that undergraduate college students who consume alcohol use to prevent alcohol-related consequences. Their hypothesis was that students who engage in more types of protective behaviors with greater frequency would be less likely to experience alcohol-related consequences. Participants consisted of a randomly selected sample of 1,355 undergraduates aged 18 years and older at a large public university. Students completed a mailed questionnaire on alcohol and health behaviors in spring 2002. The findings (after adjustment for covariates) indicated that self-protective behaviors are inversely associated with alcohol-related problems for women but not for men. The influences of gender and racial and ethnic differences are considered in relation to prevention and intervention programs aimed at reducing alcohol-related consequences on college campuses.     

Evolutionary and Cross-Cultural Perspectives on Gambling

Few attempts have been made to incorporate evolutionary and cross-cultural perspectives on gambling. This paper begins with the assumption that gambling represents a risky endeavor undertaken for the purpose of winning stakes. This assumption leads to the derivation from evolutionary theory of two hypotheses concerning the socio-demographic characteristics of gamblers: (1) gambling should be over-represented among males, and (2) among young adults. To test these hypotheses, data are drawn from three sources. A cross-cultural sample of 60 societies reveals that males are more often identified as gamblers than females, and these results do not appear to reflect reporting biases. The data are insufficient to enable conclusions about age patterns associated with gambling within this cross-cultural sample. Nationally representative studies of problem and pathological gamblers drawn from seven nation states show that such gamblers tend to be over-represented by young males, as predicted. Lastly, available demographic data on casino gambling hint at sex differences in the games played and the stakes wagered, but require further research for robust conclusions to be drawn.     

Breaking in a new function for casein kinase 2

DNA damage response mechanisms help ensure the fidelity of chromosomal transmission, and the failure of such mechanisms might lead to premature aging and cancer. A new report has established that casein kinase 2 (CK2), a protein that functions in diverse cellular processes, controls the activity of the DNA repair protein XRCC1. These results indicate that CK2 is a key participant in the cellular response to DNA damage.     

Bear ye one another’s genetic burdens: the price of diversity and complexity

Genetic variability and diversity are the result of a mutation-selection balance that acts permanently within and between species. The presence of deleterious mutations is a necessary consequence of this process and thus “the price paid by a species for its capacity for further evolution” (Haldane 1937, Am Nat 71:337–349). Recent estimations of mutation rate in the human lineage has revived the debate as to whether the high number of deleterious mutations poses a severe problem for the future of mankind. Theoretical considerations allow a scenario in which the survival of the human race is maintained by truncation selection of deleterious mutations that removes as many mutations as appear anew in every generation. In this case our genetic burden is carried by those individuals that suffer a genetic death resulting from random distribution of deleterious alleles. Nevertheless, one has to ask whether the mutation rate may set absolute limits on the complexity of a species.     

Bayesian Estimation of Survival Functions under Stochastic Precedence

When estimating the distributions of two random variables, X and Y, investigators often have prior information that Y tends to be bigger than X. To formalize this prior belief, one could potentially assume stochastic ordering between X and Y, which implies Pr(X < or = z) > or = Pr(Y < or = z) for all z in the domain of X and Y. Stochastic ordering is quite restrictive, though, and this article focuses instead on Bayesian estimation of the distribution functions of X and Y under the weaker stochastic precedence constraint, Pr(X < or = Y) > or = 0.5. We consider the case where both X and Y are categorical variables with common support and develop a Gibbs sampling algorithm for posterior computation. The method is then generalized to the case where X and Y are survival times. The proposed approach is illustrated using data on survival after tumor removal for patients with malignant melanoma.     

Dying in jail: The phenomenon of adolescent suicide in correctional facilities

Adolescent suicide is increasing in the United States and the incidence of suicide gestures and attempts in juvenile correctional facilities is high. The attitudes of correctional staff toward adolescents and toward suicidal behavior may contribute to the increase. Suicide is often the outcome of a progression of problems that have isolated the adolescent from meaningful social relationships. Correctional staff must be aware of the phenomenon of adolescent suicide and be given training to deal with it effectively within the institution. Institutional staff have commonly seen suicide gestures or attempts as acting out behavior rather than a symptom of low self-esteem or inability to cope with institutional placement. This discussion examines the phenomenon of adolescent suicide and the impact the juvenile justice system has on its occurrence. It will also include an examination of interdisciplinary interventive strategies which can be used in an institutional setting.
