The role of beta-amyloid precursor protein (beta-APP) staining in the neuropathologic evaluation of sudden infant death and in the initiation of clinical investigations of subsequent siblings

This report highlights the importance of undertaking immunohistochemical staining of the brains of infants who die unexpectedly, as it may not only assist with the evaluation of the cause of death in an individual infant but may also help with the clinical management of subsequent siblings. A 5-month-old male infant who died suddenly was found to have diffuse beta-amyloid precursor protein (beta-APP) staining in the brain, with no unusual features in his history, death scene examination, routine autopsy dissection, and ancillary tests to suggest any definite cause of death. Due to the beta-APP staining, the possibility of previous episodes of occult trauma, apparent life threatening events (ALTEs), and accidental or inflicted suffocation was raised in the autopsy report. As detailed analyses and investigations provided no supportive evidence for trauma or inflicted injury, hypoxia was clinically considered the most likely cause. Because of these concerns, sleeping oxygen saturation levels were monitored following the birth of a subsequent sibling who had normal APGAR scores and no evidence of any health problems. Oxygen desaturation to 70% occurred in association with a color change while on the postnatal ward, and a subsequent polysomnogram showed multiple episodic significant desaturations to around 80% in association with central apnea. Other testing was unremarkable. These cases demonstrate that beta-APP staining of the brain may not only provide clues as to possible mechanisms of death in pediatric forensic cases but may indicate a need for careful clinical evaluation of subsequent siblings for possible central apnea requiring oxygen therapy.     

COURT-CONNECTED PROGRAMS FOR DIVORCING PARENTS IN MICHIGAN

This article highlights the findings of a survey of court-connected programs for divorcing parents in the state of Michigan. Program and attendance information is given, and a typical program in Michigan is described. Program development and implementation issues, such as goals and program material, program management, court-mandated attendance, and program evaluation are discussed.     

Sexual abuse of vulnerable young and old men

During a 4-year period, aggregated data from Adult Protective Services case files in Virginia revealed 17 cases of sexually abused young, middle-age, and old men. The most common types of sexual abuse across age groups involved instances of sexualized kissing and fondling and unwelcome sexual interest in the individual men's bodies. The majority of alleged perpetrators were male; they typically were similar in age to the men and resided in the same residential facility. In none of the cases was the alleged perpetrator prosecuted. Only two of the men continued to be at risk of further sexual abuse by the alleged perpetrator. Implications of these data for future research and practice include a need for studies that focus on differences between male and female victims, especially concerning investigations and interventions, and for training on reporting and intervention for facilities and agencies and organizations working with victims and alleged perpetrators.     

Nanoscale analysis of the interaction between cyanoacrylate and vacuum metal deposition in the development of latent fingermarks on low-density polyethylene

Vacuum metal deposition (VMD) has been previously demonstrated as an effective development technique for latent fingermarks and in some cases has been shown to enhance prints developed with cyanoacrylate (CA) (superglue) fuming. This work utilizes scanning electron microscopy (SEM) to investigate the interactions of the two development techniques when applied to latent fingermarks on low-density polyethylene. CA is shown to act principally on the eccrine deposits around sweat pores, where polymerization results in long polymer fibrils a few 100 nm in width. Subsequent VMD processing results in additional areas of development, for example, between pores. However, the primary mode of deposition of zinc is by interaction with the polymerized CA, the fibrils of which become decorated with zinc nanoparticles. Areas with limited CA deposition and no significant polymerization are also enhanced with the VMD process, resulting in increased print development.     

Transitions in the negotiations on climate change: from prisoner’s dilemma to chicken and beyond

Frequently, international environmental negotiations have been analyzed in two-agent (2 × 2) games. Yet, in order to involve additional strategies, (3 × 3) games gained attention recently. We employ such a (3 × 3) game setting in order to depict international negotiations on climate change and integrate both the prisoner’s dilemma and the chicken games in this setting. We analyze transitions of negotiation states and describe how ancillary benefits and first-mover advantages influence agents’ behavior in the negotiations, when three different strategies or levels of climate protection efforts are available. Finally, we also integrate strategies to mitigate and to adapt to climate change into the analysis in the (3 × 3) game setting.     

Revisiting the role of communication in adolescent intimate partner violence

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.
