A review of blunt force injury homicides of children aged 0 to 5 years in bexar county, Texas, from 1988 to 2009

ABSTRACT: It is essential that clinical physicians, medical personnel, medical examiners, and law enforcement agencies understand the types of injuries seen and demographics of children affected by intentional blunt force as this understanding can be crucial to the death and/or criminal investigations. An understanding of the injuries can also assist in drawing conclusions regarding how those injuries could have been sustained. This study discusses the types and patterns of injuries seen in blunt force homicides in children younger than 6 years. The study found that male infants are more often intentionally injured than are female infants and that fatal head injuries most frequently occur in the first year of life, whereas most fatal thoracoabdominal injuries occur in the first 3 years of life. In children with head injuries, subdural hemorrhage was the most common finding, followed by subarachnoid hemorrhage. In 2.5% of deaths due to head injury, concurrent neck injury was seen, a percentage far lower than previous literature would suggest if shaking was the primary mechanism of injury. Twelve legal confessions were also reviewed, none of which disclosed a pure mechanism of shaking the infant.     

Does Attentional Control Mediate the Association Between Adverse Early Experiences and Child Physical Abuse Risk?

The present study examined the extent to which attentional control mediates the relationship between adverse early life experiences (e.g., harsh discipline, low perceived support) and child physical abuse (CPA) risk in adulthood. Participants included 138 general population parents (30.4% fathers and 69.6% mothers) who completed self-report measures of early life experiences, attentional control, and CPA risk. Results revealed that attentional control partially mediated the association between adverse early environment and CPA risk scores, Sobel test = 2.65, SE = 0.86, p = .007. More specifically, individuals exposed to adverse early environments (characterized by harsh discipline and/or low perceived support) reported lower levels of attentional control, which in turn was associated with increased risk of hostile, aggressive, and abusive parenting.     

STR melting curve analysis as a genetic screening tool for crime scene samples

In this proof-of-concept study, high-resolution melt curve (HRMC) analysis was investigated as a postquantification screening tool to discriminate human CSF1PO and THO1 genotypes amplified with mini-STR primers in the presence of SYBR Green or LCGreen Plus dyes. A total of 12 CSF1PO and 11 HUMTHO1 genotypes were analyzed on the LightScanner HR96 and LS-32 systems and were correctly differentiated based upon their respective melt profiles. Short STR amplicon melt curves were affected by repeat number, and single-source and mixed DNA samples were additionally differentiated by the formation of heteroduplexes. Melting curves were shown to be unique and reproducible from DNA quantities ranging from 20 to 0.4 ng and distinguished identical from nonidentical genotypes from DNA derived from different biological fluids and compromised samples. Thus, a method is described which can assess both the quantity and the possible probative value of samples without full genotyping.     

The Institutional Ombudsman: A University Case Study

The experience of a university ombudsman is utilized to examinetraditional elements within the organizational ombudsman role. History andcontext of role and person in it are discussed in relation to organizationexperience, independence, impartiality and neutrality, investigative power,responsibility for recommendations, and confidentiality. Implications ofthese elements in practice are described, and then explored through threecase examples.     

Incidental findings in pediatric research

The approach to incidental research findings in children emerges by considering the child-parent relationship and balancing divergent interests and preferences. Incidental findings with clear and proximate clinical importance should be disclosed to both. We recommend that particularly sensitive or private information (e.g., pregnancy or drug use) should be disclosed to the adolescent first, while particularly serious information (e.g., cancer) should first be disclosed to the parent. These approaches allow the researcher to form an alliance with one party prior to engaging the other. However, unlike clinical settings, where there may be presumptive expectations of confidentiality about sharing information within the family, in most research settings it is reasonable to plan to disclose such information to both parties. It is important to communicate this plan during the informed consent process separately to adolescents to avoid enrolling adolescents when sensitive incidental findings such as pregnancy and drug use may be detected. The approach to incidental findings without clear and proximate benefit is challenging. Researchers should plan more limited disclosure of such incidental findings for pediatric participants than for adult participants.     

Action research in mental health: acute care teams

Action research applies knowledge and research findings to practical problems in order to strengthen the capability of the work unit, to contribute to the personal growth and satisfaction of organization members, and to improve theory. An action research project studying acute care teams at a state residential psychiatric facility found that foreign-born physicians chair high-performing teams. This unexpected result strengthens theories of diversity, status inconsistency, and project team effectiveness.     

Routine Activity Theory and Sexual Deviance Among Male College Students

Much research on sexual deviance on university and college campuses is limited by its narrow focus on group affiliation. In this study, it is argued that prior deviance and opportunity serve as more robust predictor variables of sexual deviance. Using a sample of 304 male college students from four universities within the Ohio Valley Conference, this paper utilizes Analytic moment structures (AMOS) analyses to examine the relationship between prior deviance and sexual deviance. Results support the assumption that sexual aggression is significantly (β=.17) mediated or accounted for by opportunity. Overall, the relationships among variables lend support to the argument that alternative explanations of sexual deviance may provide a better understanding of such a complex societal problem.
