Protective Factors Against the Impact of School Bullying Perpetration and Victimization on Young Adult Externalizing and Internalizing Problems

School-based bullying perpetration and victimization is common worldwide and has profound impacts on student behavior and mental health. However, few studies have examined young adult outcomes of bullying perpetration or victimization. Research on factors that protect students who have bullied or been bullied is also lacking. This study examined young adult externalizing and internalizing problems (age 18–19 years) and adolescent protective factors related to self-reported bullying perpetration and victimization among over 650 Victorians ages 16–17 years. Opportunities for prosocial involvement in the family lessened subsequent involvement in nonviolent antisocial behavior, as an outcome of prior bullying. High academic performance and having strategies to cope with stress reduced young adult depressive symptoms for participants who had been victims of bullying. The implications for bullying prevention and early intervention programs are discussed.     

The ForAPP: Forensic Ancestry Prediction Pipeline for the interpretation of ancestry informative markers

Interpretation of ancestry informative markers (AIMs) in a forensic case can be time-consuming as different tools are used that need to be initiated separately. We develop the ForAPP; an open-source pipeline (running offline) that initiates multiple ancestry prediction analyses and summarizes results in an interactive interface for interpretation of autosomal ancestry-informative markers.     

Make it "SNPPY" - Updates to SRM 2391d: PCR-Based DNA Profiling Standard

Standard Reference Material (SRM) 2391d: PCR-Based DNA Profiling Standard was released to the forensic community in 2019. Next Generation Sequencing (NGS) was used as the primary method of certification, where certified values were assigned when a high coverage sequence string was available for a marker. Using NGS to assign values has allowed for additional marker sets beyond short tandem repeat (STR) loci, including single nucleotide polymorphisms (SNPs) and mitochondrial DNA (mtDNA) whole genome sequences, to be included in the Certificate of Analysis (COA). Since the 2019 release, several commercial NGS panels have become available including the Verogen ForenSeq mtDNA Control Region, mtDNA Whole Genome, MainstAY, and Kintelligence Kits. In addition, three community Ion AmpliSeq panels from Thermo Fisher (MH-74 Plex, VISAGE, and Y-SNP) are now available. While the mtDNA whole genome sequence for the components are already included and no new STR markers are introduced by MainstAY, the other recently released panels allow for the inclusion of > 11,000 additional SNPs (e.g., identity, ancestry, phenotype, kinship, and X- and Y-SNPs) and 74 microhaplotypes to the COA for SRM 2391d in an update completed by fall of 2022.     

A LONGITUDINAL TEST OF SOCIAL DISORGANIZATION THEORY: FEEDBACK EFFECTS AMONG COHESION,SOCIAL CONTROL,AND DISORDER*

Social disorganization theory holds that neighborhoods with greater residential stability, higher socioeconomic status, and more ethnic homogeneity experience less disorder because these neighborhoods have higher social cohesion and exercise more social control. Recent extensions of the theory argue that disorder in turn affects these structural characteristics and mechanisms. Using a data set on 74 neighborhoods in the city of Utrecht in the Netherlands spanning 10 years, we tested the extended theory, which to date only a few studies have been able to do because of the unavailability of neighborhood‐level longitudinal data. We also improve on previous studies by distinguishing between the potential for social control (feelings of responsibility) and the actual social control behavior. Cross‐sectional analyses replicate earlier findings, but the results of longitudinal cross‐lagged models suggest that disorder has large consequences for subsequent levels of social control and residential instability, thus leading to more disorder. This is in contrast to most previous studies, which assume disorder to be more a consequence than a cause. This study underlines the importance of longitudinal data, allowing for simultaneously testing the causes and consequences of disorder, as well as the importance of breaking down social control into the two dimensions of the potential for social control and the actual social control behavior.     

Trichophyton Mentagrophytes Perforates Hair of Adult Corpses in the Gaseous Period*

Abstract: Despite the substantial literature on mycology, there are still limited reports of the interaction between fungi and human hosts in the postmortem period. Thus, the main goal of this study was to investigate the in vitro perforation test using Trichophyton mentagrophytes on hair from adult corpses in the postmortem period (gaseous period). The protocol was carried out with positive (prepubescent children’s hair) and negative controls (healthy adult hair) as well. One strain of Trichophyton rubrum was also used as a negative perforation control. Perforations were found in all the hair samples from corpses and prepubescent children after 12–14 days exposure to T. mentagrophytes and were absent in the hair samples of healthy adults. Furthermore, hair perforation was not observed with T. rubrum. Our preliminary findings suggest the use of T. mentagrophytes as a potential marker of the death interval in forensic science.     

EXPLAINING THE GENDER GAP IN CRIME: THE ROLE OF HEART RATE

Although it is well established that males engage in more crime compared with females, little is known about what accounts for the gender gap. Few studies have been aimed at empirically examining mediators of the gender–crime relationship in a longitudinal context. In this study, we test the hypothesis that a low resting heart rate partly mediates the relationship between gender and crime. In a sample of 894 participants, the resting heart rate at 11 years of age was examined alongside self‐reported and official conviction records for overall criminal offending, violence, serious violence, and drug‐related crime at 23 years of age. A low resting heart rate partially mediated the relationship between gender and all types of adult criminal offending, including violent and nonviolent crime. The mediation effects were significant after controlling for body mass index, race, social adversity, and activity level. Resting heart rate accounted for 5.4 percent to 17.1 percent of the gender difference in crime. This study is the first to produce results documenting that lower heart rates in males partly explain their higher levels of offending. Our findings complement traditional theoretical accounts of the gender gap and have implications for the advancement of integrative criminological theory.     

The Programme de recherche en démographie historique: past,present and future developments in family reconstitution

The Programme de recherche en démographie historique (Historical Demography Research Programme) (PRDH), founded in 1966 and based at the Département de Démographie of the Université de Montréal, has since its inception featured a central project, a family reconstitution database of Quebec’s Catholic population from 1621 to 1799 named the Registre de la population du Québec ancien (Population Register of Historic Quebec) (RPQA). This article, which marks the fiftieth anniversary of the project, explores the development of the RPQA over the five decades in the context of similar international databases, explains the current state of the database as well as our record linkage methodology, describes an important collaboration now underway to build a larger Quebec historical data infrastructure, outlines new and renewed international collaborations, and summarizes research conducted using these data as well as future research possibilities. The particular geographic context, historical development and manageable colonial population size of Quebec favoured family reconstitution of the whole colony from the beginning of the project. Today, the RPQA comprises 438,193 individual biographies and 74,000 family files encompassing up to nine generations. To reconstitute families, we must identify and incorporate into the database all demographic events, including those whose existence can only be inferred through other sources. Future efforts to link nineteenth-century parish acts will need to deal with large case counts, mixed Catholic–Protestant marriages, and increased geographic and social mobility. The integration of complementary data will provide information on household co-residence, occupations, help track the destinies of mixed-religion persons and persons outside nuclear families and provide additional points of observation.

A Longitudinal Investigation of the Development of Weight and Muscle Concerns Among Preadolescent Boys

The study examined the impact of body mass index (BMI), negative affect, self-esteem, and sociocultural influences in the development of weight and muscle concerns among preadolescent boys. Body dissatisfaction, importance placed on weight and muscles, weight loss strategies, and strategies to increase muscles were evaluated. Participants were 237 boys aged between 8 and 11 years who were tested at three assessment periods 8 months apart. The main predictor of boys’ body change strategies was their perceived pressures to modify weight and muscles from parents, peers, and the media. The other main predictor of boys’ body change strategies and the sole predictor of body dissatisfaction was BMI. Self-esteem and negative affect were found to be weak and generally nonsignificant predictors of boys’ body image concerns and body change strategies. Additional studies that examine the risk and protective factors associated with boys’ weight and muscle concerns are needed to assist in the development of prevention programs for preadolescent boys.Lina Ricciardelli is an Associate Professor at Deakin University.
