Postmortem Computed Tomography in Firearm Homicides: A Retrospective Case Series,

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.     

Perceptions of Problem Behavior in Adolescents’ Families: Perceiver,Target, and Family Effects

Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’ behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect on informant reports of problem behavior has not been previously reported.     

Parents and Peers as Social Influences to Deter Antisocial Behavior

Growth curve analyses were used to investigate parents’ and peers’ influence on adolescents’ choice to abstain from antisocial behavior in a community-based sample of 416 early adolescents living in the Southeastern United States. Participants were primarily European American (91%) and 51% were girls. Both parents and peers were important influences on the choice to abstain from antisocial behavior. Over the four-year period adolescents relied increasingly on parents as influences and relied less on peers as influences to deter antisocial behavior. Significant gender differences emerged and suggested that female adolescents relied more on social influences than did male adolescents but that as time progressed male adolescents increased the rate at which they relied on peers. Higher family income was associated with choosing peers as a social influence at wave 1, but no other significant income associations were found. Understanding influences on adolescents’ abstinence choices is important for preventing antisocial behavior.

Kazin’s Trilling: A Cold War Portrait

This essay describes the eminent Americanist, critic, and New York intellectual, Alfred Kazin’s creation of a Lionel Trilling “character” in his 1978 autobiography, New York Jew, and his use of that character to critique significant features of the country’s Cold War literary culture. Among these are: the narrowing and hardening of intellectual discourse in a cultural-political climate dominated by the “liberal consensus,” the discrediting of the progressive impulse in American writing, the subordination of “class” to “culture” in evaluations of American writers, and the changing status of Jews and Jewish writers in post-war America. Tapping into strong personal feelings, Kazin creates in Trilling a harsh, thoughtful and compelling portrait of an era.     

Is Antifa a Terrorist Group?

Starting in 2016, a number of protests and physical confrontations aimed at individuals and groups associated with right wing politics in the United States have been attributed to an ill-defined entity called “antifa”: short for anti-fascist. A high profile example took place in Charlottseville, Virginia on August 11-12, 2017. During two days of conflict and violence, anti right wing protesters clashed with right wing supporters. During the second day of the confrontation, a right-wing supporter drove a car into a crowd of protesters, killing one person and injuring 35 others. While many antifa supporters see it as a defense against right wing extremism, some on the right view supporters instead as terrorists. I tackle these issues in this essay by applying the guidelines of the Global Terrorism Database (GTD) to determine whether the actions by antifa supporters during the Charlottesville incident consitute terrrorism. I conclude that while the events share many characteristics of terrorist attacks, they do not include all of the elements of terrorism required by the GTD. I also question whether antifa can be considered to constitute a “group” at this point in time. My essay highlights how complicated it is to distinghish terrorism from other forms of illegal violence.     

Individual Differences in Adolescents’ Emotional Reactivity across Relationship Contexts

Understanding individual differences in adolescents’ ability to regulate emotions within interpersonal relationships is paramount for healthy development. Thus, the effect of individual vulnerabilities (depressive affect, social anxiety, self-blame, and coping efficacy problems) on the transmission of emotional reactivity in response to conflict from family to peers (friends and romantic partners) was prospectively examined across six waves of data in a community-based sample of 416 adolescents (M_age Wave 1?=?11.90, 51% girls). Multiple-group models estimated in structural equation modeling suggested that youth who were higher in social anxiety or coping efficacy problems were more likely to transmit emotional reactivity developed in the family-of-origin to emotional reactivity in response to conflict in close friendships. Additionally, those youth higher in self-blame and depressive affect were more likely to transmit emotional reactivity from friendships to romantic relationships.
