Predictors of the Onset of Sexual Violence Perpetration in Adolescence and Emerging Adulthood.

To identify factors in adolescence that predict the onset of sexual violence in adolescence and young adulthood. Data were analyzed from six survey waves of the longitudinal Growing up with Media Study (2008-2018) conducted in the USA. Participants were 778 youth 13-18 years old at baseline, who completed online surveys assessing sexual violence behaviors and predictors.

Childhood Gender Diversity and Mental Health: Protocol for the Longitudinal, Observational Gender Journey Project.

Background: Prepubertal transgender, nonbinary, and gender-diverse (TGD) children (ie, those asserting gender identity, expressing gender-role behavior outside of culturally defined norms for their sex registered at birth, or both) are presenting in greater numbers to pediatric gender clinics across the United States and abroad. A large subset of TGD children experiences gender dysphoria, that is, distress that arises from the incongruence between gender identity and sex registered at birth. A lack of consensus exists regarding care for prepubertal TGD children due, in part, to a dearth of empirical research on longitudinal developmental trajectories of gender identity, role behavior, and gender dysphoria (when present).

Modulation of Fe-Fe distance and spin in diiron complexes using tetradentate ligands with different flanking donors.

Here we report the synthesis and characterization of diiron complexes containing triaryl N and NS ligands derived from -phenylenediamine. The complexes display significant differences in Fe-Fe distances and magnetic properties that depend on the identity of the flanking NMe and SMe donor groups.

Electronic Free Energy Surface of the Nitrogen Dimer Using First-Principles Finite Temperature Electronic Structure Methods.

We use full configuration interaction and density matrix quantum Monte Carlo methods to calculate the electronic free energy surface of the nitrogen dimer within the free-energy Born-Oppenheimer approximation. As the temperature is raised from = 0, we find a temperature regime in which the internal energy causes bond strengthening. At these temperatures, adding in the entropy contributions is required to cause the bond to gradually weaken with increasing temperature.

Testing the Impact of the Whole-Day Good Behavior Game on Aggressive Behavior: Results of a Classroom-Based Randomized Effectiveness Trial.

Three generations of developmental epidemiologically based randomized field trials of the Good Behavior Game (GBG) have been delivered to Baltimore elementary schools. With the collaboration of family and community partners, all three trials were directed at decreasing proximal targets of aggressive behavior and improving learning in first-grade classrooms with distal mental health and substance abuse outcomes. GBG is a group-contingent classroom behavior management strategy that promotes classmate/peer concern for each child's positive behavior by rewarding teams with below-criterion levels of aggressive, disruptive behavior.

The Sign Problem in Density Matrix Quantum Monte Carlo.

Density matrix quantum Monte Carlo (DMQMC) is a recently developed method for stochastically sampling the -particle thermal density matrix to obtain exact-on-average energies for model and ab initio systems. We report a systematic numerical study of the sign problem in DMQMC based on simulations of atomic and molecular systems. In DMQMC, the density matrix is written in an outer product basis of Slater determinants.

Iron-Catalyzed Halogen Exchange of Trifluoromethyl Arenes*.

The facile production of ArCF X and ArCX from ArCF using catalytic iron(III)halides is reported, which constitutes the first iron-catalyzed halogen exchange for non-aromatic C-F bonds. Theoretical calculations suggest direct activation of C-F bonds by iron coordination. ArCX and ArCF X products of the reaction are synthetically valuable due to their diversification potential.

Introduction to the Special Issue on "Promoting a Culture of Prevention: an International Perspective".

The primary goal of this special issue is to showcase novel, theory-driven, creative, and rigorous contributions to our understanding of the existence and development of a culture of prevention and readiness to prevent. The term "culture of prevention" is neither a set of practical guidelines nor a leading theory. Instead, it is a multidimensional term representing the general orientation and readiness of a group of people (be it a family, community, school, organization, nation, etc.

Groups of Sexual Violence Perpetration in a National Sample of Youth 13-25 Years of Age.

Little is known about how specific forms of sexual violence (SV) perpetration group together and how youth transition between these groups over time. Between 2011 and 2016, four waves of data were collected online nationally from 1129 13-25-year-olds. Six forms of SV perpetration were assessed: sexual harassment, online sexual harassment, sexual assault, coercive sex, attempted rape, and rape.

Using Density Matrix Quantum Monte Carlo for Calculating Exact-on-Average Energies for Hamiltonians in a Finite Basis Set.

We here apply the recently developed initiator density matrix quantum Monte Carlo (i-DMQMC) to a variety of atoms and molecules in vacuum. i-DMQMC samples the exact density matrix of a Hamiltonian at finite temperature and combines the accuracy of full configuration interaction quantum Monte Carlo (FCIQMC)-full configuration interaction (FCI) or exact energies in a finite basis set-with finite temperature. In order to explore the applicability of i-DMQMC for molecular systems, we choose to study a recently developed test set by Rubenstein and co-workers: Be, HO, and H at near-equilibrium and stretched geometries.

Can Machine Learning Improve Screening for Targeted Delinquency Prevention Programs?

The cost-effectiveness of targeted delinquency prevention programs for children depends on the accuracy of the screening process. Screening accuracy is often poor, resulting in wasted resources and missed opportunities to avert negative outcomes. This study examined whether screening approaches based on logistic regression or machine learning algorithms could improve accuracy relative to traditional sum-score approaches when identifying boys in the 5th grade (N = 1012) who would be repeatedly arrested for violent and serious crimes from ages 13 to 30.

The Influence of Redox-Innocent Donor Groups in Tetradentate Ligands Derived from -Phenylenediamine: Electronic Structure Investigations with Nickel.

The continued development of redox-active ligands requires an understanding as to how ligand modifications and related factors affect the locus of redox activity and spin density in metal complexes. Here we describe the synthesis, characterization, and electronic structure of nickel complexes containing triaryl NNNN () and SNNS () ligands derived from -phenylenediamine. The tetradentate ligands in and were investigated and compared to those in metal complexes with compositionally similar ligands to determine how ligand-centered redox properties change when redox-active flanking groups are replaced with redox-innocent NMe or SMe.

Fully Quantum Embedding with Density Functional Theory for Full Configuration Interaction Quantum Monte Carlo.

We here develop a fully quantum embedded version of initiator full configuration interaction quantum Monte Carlo (-FCIQMC) and apply it to study an ionic bond (lithium hydride, LiH) and a covalent bond (hydrogen flouride, HF) physisorbed to a benzene molecule. The embedding is performed using a recently developed Huzinaga projection operator approach, which affords good synergy with -FCIQMC by minimizing the number of orbitals in the calculation. When considering the dissociation energy of these bonds into closed-shell ionic fragments, we find that -FCIQMC embedded in density functional theory (-FCIQMC-in-DFT) delivers comparable accuracy with coupled cluster singles and doubles with perturbative triples embedded in density functional theory (CCSD(T)-in-DFT).

The Gender Minority Stress and Resilience Measure: Psychometric Validity of an Adolescent Extension.

Objective: Minority stress contributes to several physical and psychological problems in sexual and gender minorities but is largely understudied in transgender/gender-nonconforming (TGNC) individuals, particularly TGNC adolescents. The availability of psychometrically sound measures of adolescent minority stress can help improve assessment and treatment planning in this area. This original research study examined whether an existing measure of TGNC-related minority stress and resilience among adults could retain construct and psychometric validity when administered to TGNC adolescents.

Longitudinal Assessment Design and Statistical Power for Detecting an Intervention Impact.

In evaluating randomized control trials (RCTs), statistical power analyses are necessary to choose a sample size which strikes the balance between an insufficient and an excessive design, with the latter leading to misspent resources. With the growing popularity of using longitudinal data to evaluate RCTs, statistical power calculations have become more complex. Specifically, with repeated measures, the number and frequency of measurements per person additionally influence statistical power by determining the precision with which intra-individual change can be measured as well as the reliability with which inter-individual differences in change can be assessed.

Maternal Alcohol Consumption During the Perinatal and Early Parenting Period: A Longitudinal Analysis.

Objectives: Despite potential health risks for women and children, one in five women report alcohol use during pregnancy and a significant proportion of those who quit during pregnancy return to drinking post-delivery. This study seeks to understand the longitudinal patterns of alcohol consumption before, during pregnancy and post-delivery, and the role of maternal characteristics for purposes of informing prevention design.

Methods: General growth mixture models were used to describe the average developmental patterns of maternal weekly drinking quantity at six time points, from preconception through child entering kindergarten, as well as heterogeneity in these patterns among 9100 mothers from the Early Childhood Longitudinal Study representing the 2001 US national birth cohort.

The use of assistive technology for cognition to support the performance of daily activities for individuals with cognitive disabilities due to traumatic brain injury: The current state of the research.

Background: Many individuals with traumatic brain injury (TBI) are young and could have many years of productivity ahead of them. However, cognitive impairments may hinder individuals' ability to perform daily tasks. Assistive technology for cognition (ATC) can be effective in helping compensate for cognitive impairments.

Gender-specific profiles of adverse childhood experiences, past year mental and substance use disorders, and their associations among a national sample of adults in the United States.

Purpose: This study examined profiles of adverse childhood experiences (ACEs) and mental and substance use disorders (MSUDs), and associations between distinct profiles of ACEs and MSUDs.

Methods: Participants were adults (N = 34, 652) involved in the National Epidemiologic Survey on Alcohol and Related Conditions. Latent class analysis was used to examine both profiles of ten ACEs and ten past year MSUDs.

Maternal patterns of postpartum alcohol consumption by age: a longitudinal analysis of adult urban mothers.

The purpose of this study is to investigate a) longitudinal patterns of maternal postpartum alcohol use as well as its variation by maternal age at child birth and b) within maternal age groups, the association between other maternal characteristics and alcohol use patterns for the purposes of informed prevention design. Study sample consists of 3397 mothers from the Fragile Families and Child Wellbeing Study representing medium and large US urban areas. Maternal drinking and binge drinking were measured at child age 1, 3, and 5 years.

Mental disorders associated with subpopulations of women affected by violence and abuse.

Violence against women is a major public health problem associated with mental disorders. Few studies have examined the heterogeneity of interpersonal violence and abuse (IVA) among women and associated mental health problems. Latent class analysis was used to identify subpopulations of women with similar lifetime histories of IVA victimization and to examine 10 associated past-year mental disorders.

The evaluation of two first-grade preventive interventions on childhood aggression and adolescent marijuana use: a latent transition longitudinal mixture model.

Aggressive, disruptive behavior during early childhood has been linked to a number of later negative outcomes, one of them being adolescent marijuana use. This study evaluates the impact of two first-grade universal interventions (classroom-centered and family-school partnership) on the development of aggression in early childhood (grades 1-3) and marijuana use in adolescence (grades 8-12) via a latent transition longitudinal mixture model. For males, despite the significant proximal impact of the classroom-centered intervention on trajectory class membership of early childhood aggression, as well as the significant association between aggression trajectory class membership and marijuana use longitudinal latent class membership, the predicted probabilities of being in the high frequency marijuana use class did not differ significantly by intervention status, though in the expected direction.

Youth aggressive/disruptive behavior trajectories and subsequent gambling among urban male youth.

This study examines the association between aggressive/disruptive behavior development in two distinct developmental periods-childhood (i.e., Grades 1-3) and early adolescence (i.

The use of multiple versus single assessment time points to improve screening accuracy in identifying children at risk for later serious antisocial behavior.

Guided by Kraemer et al.'s (Psychological Methods, 3:257-271, 1999) framework for measuring the potency of risk factors, we sought to improve on the classification accuracy reported in Petras et al. (Journal of the American Academy of Child and Adolescent Psychiatry 43:88-96, 2004a) and Petras et al.

Impulsivity trajectories and gambling in adolescence among urban male youth.

Aim: Building on the recent emerging literature on the impulsivity trajectory-gambling association, this study investigated the association between developmental trajectories of teacher-rated impulsivity in early adolescence (ages 11-15 years) and subsequent gambling and gambling problems (i.e. at-risk and problem gambling) by age 19.
