Based on Jessor's problem behavior theory (PBT; R. Jessor, 1987, Problem-behavior theory, psychosocial development, and adolescent problem drinking, British Journal of Addiction, Vol. 82, pp. 331-342), the comparability of a second-order problem behavior model (SPBM) was investigated employing structural equation modeling (SEM) and latent mean differences in problem behavior engagement were examined among racial/ethnic adolescents. Within a span of nearly 25 years, this study represents the first nationally representative sample of Latino and African American adolescents utilized in testing Jessor's PBT and problem behavior syndrome (PBS). Using a sample of 5,831 Latino, African American, and European American adolescents drawn from the National Longitudinal Study of Adolescent Health, a series of invariance tests evidenced support for Jessor's PBT and PBS. Latent mean difference test results evidenced significant differences in problem behaviors (e.g., academic failure [AF], aggression [AG], substance use [SU], and risky sexual activity[RSA]) across racial/ethnic adolescent groups, which could be explained partially by PBS. A discussion of findings, limitations, and recommendations for future research is presented.

Statement Of Problem: Staining at the gingival margin could impact denture longevity, but the behavior of gingival colored composite resins (GCCs) in this area remains unclear.
Purpose: This in vitro study evaluated surface staining, microleakage, and push-out bond strength at the gingival margin of artificial teeth, comparing two consistencies of GCCs with two resin base materials.
Material And Methods: Specimens included artificial teeth (Ivostar; Ivoclar AG) and two acrylic resin base materials: conventional (Ondacryl; Clássico) and high-impact (Diamond D; Keystone Industries) (n=300).

In adaptive beamforming, the array signal processing adjusts its sensor delays and weights based on the incoming data. In conventional beamforming, these parameters are instead given from a predefined model. Adaptive beamformers can improve measurement precision by dynamically rejecting spatial interference.

Lung cancer remains a predominant cause of cancer-related deaths, with notable disparities in incidence and outcomes across racial and gender groups. This study addresses these disparities by developing a computational framework leveraging explainable artificial intelligence (XAI) to identify both patient- and cohort-specific biomarker genes in lung cancer. Specifically, we focus on two lung cancer subtypes, Lung Adenocarcinoma (LUAD) and Lung Squamous Cell Carcinoma (LUSC), examining distinct racial and sex-specific cohorts: African American males (AAMs) and European American males (EAMs).

Domestic violence is a commonplace and serious societal problem with vast public health and economic consequences. Childhood exposure to domestic violence can blight children's biological and social development. Often, local police departments are first responders to domestic violence.

Statement Of Problem: Translucent zirconias are promising materials for monolithic prostheses. However, information on their optical behavior after sintering and aging protocols is scarce.
Purpose: The purpose of this in vitro study was to evaluate the color and translucency of zirconia subjected to different sintering temperatures and aging.
