Bullies, Gangs, Drugs, and School: Understanding the Overlap and the Role of Ethnicity and Urbanicity

Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying—as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement—and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.     

Examining Associations Between Race, Urbanicity, and Patterns of Bullying Involvement

Research on the role of race and urbanicity in bullying involvement has been limited. The present study examined bullying involvement subgroups that relate to race, urbanicity, and the perceived reason for the bullying. Self-report data were collected from 10,254 middle school youth (49.8 % female; 62.4 % Caucasian, 19.0 % African American, and 5.6 % Hispanic) and latent class analyses were used to identify three subtypes of bullying involvement: low involvement (50 %), victim (31.3 %), and bully-victim (18.7 %). Irrespective of urbanicity (urban vs. non-urban), African American youth were more likely to be members of either the victim or bully-victim classes than the low involvement class. Further exploration of the community context suggested that urbanicity was associated with the increased likelihood of having been racially bullied. Urban bully-victims were also more likely to have been bullied about money than non-urban bully-victims. Findings underscore the importance of addressing both race and urbanicity for culturally sensitive prevention programming.     

Separation of overlapping fingermarks by Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging

Latent fingermarks are impressions of the skin ridge pattern that are transferred by the accidental contact of fingertips with a deposition surface. The ability to enhance, lift and produce an image of a latent fingermark, for comparison and suspect match against a central fingerprint database, provides forensic investigators with what is still considered one of the most powerful means of biometric identification to date. Identification relies on the recovery, visualisation, extraction and comparison of local characteristics of the ridge pattern (minutiae) that are unique to individuals. Therefore, both for manual inspection of the minutiae and using automated ridge extraction algorithms, the clearer the ridge details, the more reliable and successful the match. Overlapping fingermarks pose a remarkable challenge in this context and are often encountered when developing marks from crime scenes. Here we propose the use of Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI MSI) to separate overlapping fingermarks using ion signals that are characteristic of each fingermark and that may be endogenous or exogenous in nature. In this work we show that the methodology works in a number of different scenarios both using manual inspection of the spectrum profile or a much quicker multivariate statistical analysis.     

Dental hygiene students' matching accuracy when comparing antemortem dental radiographs and oral photographs to simulated postmortem WinID3® odontograms

Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students' match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3^® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students (n = 31) was presented information on WinID3^® interpretation, then presented with 5 mismatched cases and asked to visually interpret each to make 10 total matches; five based on AM FMS with simulated PM WinID3^® odontograms and five based on AM photographs with PM WinID3^® odontograms. Match accuracy scores ranged from 41.9% to 58.1% for cases with 1–10 identifiers, and 77.4% to 93.5% for cases with 11–40 identifiers. Accuracy when matching AM radiographs to PM odontograms versus AM photographs to PM odontograms was compared and revealed no statistical differences in match accuracy depending on image type (p = 0.388 to 1.000). Results of this pilot study suggests transferable match accuracy skills resulted from the participants' dental hygiene formal education. These baseline skills with additional specialized training support the rationale for dental hygienists serving on DVI teams. More research is needed in education and practice when preparing dental hygienists for forensic-based service.     

Examination of the Relationship Between Parental Satisfaction and Child Maltreatment Potential While Considering Social Desirability

Parental dissatisfaction with children appears to be associated with child maltreatment. However, little is known regarding the specific domains of parental dissatisfaction that may increase child maltreatment potential, particularly in perpetrators of child maltreatment where substance abuse is present. In this study, responses to the Child Abuse Potential Inventory (CAPI) and a scale measuring parental satisfaction in 11 domains were examined in a sample of 82 mothers who were referred for treatment of substance abuse and child neglect by the local child protective service agency. Results indicated that mothers were relatively most satisfied with their children overall, and least satisfied in domains that were relevant to discipline (i.e., following house rules, compliance, reaction to redirection and punishment, completion of chores). Five of the 11 areas of parental satisfaction that were assessed evidenced negative correlations with child abuse potential, indicating that as satisfaction increased, abuse potential decreased. However, when correlation analyses excluded participants with elevated CAPI Lie scale scores (a measure of social desirability), only overall happiness demonstrated a significant negative correlation with child abuse potential. These results suggest that while associations are present among measures of parental satisfaction and child abuse potential, these associations are moderated to some extent by social desirability, which may help explain some of the inconsistencies reported in prior studies of parental satisfaction and child maltreatment potential.     

Comparing social,emotional, and behavioral health risks among youth attending public versus parochial schools

Parochial schools are assumed to provide better social and academic experiences; however, few studies account for selection bias when comparing with public schools. This study contrasted public versus parochial schools using propensity score matching across a range of outcomes (e.g., perceptions of school, emotional symptoms, substance use, bullying). Using a sample of 58 public and 5 parochial high schools, the nonmatched analyses suggested a significant advantage for parochial schools students (e.g., better on 23 of 32 indicators). However, the propensity score matched analyses revealed nine differences (e.g., weapon carrying, smoking), two of which (i.e., stress and cyberbullying) favored public schools. While at first glance parochial schools generally appear to be healthier and safer learning environments, accounting for selection bias, the gap was narrowed. Students in parochial schools may struggle with issues related to social, emotional, and behavioral health risk, and thus prevention programs should also be implemented in these settings.     

Youth and parental attitudes toward fighting

Certain parenting behaviors have been linked with youth aggression and violence, but less is known about whether parents' attitudes toward fighting are a risk factor for children's aggressive behavior problems and future injury risk. Social cognitive theory suggests that parents' beliefs about fighting and retaliation may influence their children's attitudes toward fighting and aggression. The authors examined the associations among parental and youth attitudes toward fighting, parent-child relationships, and youth aggressive behavior in adolescents at great risk for future interpersonal violence. Data came from 72 parents and their adolescents (aged 12 to 17 years, 89% African American), who presented to an emergency department for youth's assault-related injuries. Analyses revealed an association between parents' and youth's attitudes toward fighting. Youth's and parents' attitudes were positively correlated with aggressive behavior, fighting, and school suspension. Parents' attitudes predicted youth's aggressive behavior, even after controlling for youth's attitudes. The findings suggest that interventions for high-risk youth should target the fighting-related attitudes of both parents and youth.
