Longitudinal Bi-directional Relationships Between Sleep and Youth Substance Use

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.     

Reliability of Craniofacial Superimposition Using Three‐Dimension Skull Model

Craniofacial superimposition is a technique potentially useful for the identification of unidentified human remains if a photo of the missing person is available. We have tested the reliability of the 2D‐3D computer‐aided nonautomatic superimposition techniques. Three‐dimension laser scans of five skulls and ten photographs were overlaid with an imaging software. The resulting superimpositions were evaluated using three methods: craniofacial landmarks, morphological features, and a combination of the two. A 3D model of each skull without its mandible was tested for superimposition; we also evaluated whether separating skulls by sex would increase correct identifications. Results show that the landmark method employing the entire skull is the more reliable one (5/5 correct identifications, 40% false positives [FP]), regardless of sex. However, the persistence of a high percentage of FP in all the methods evaluated indicates that these methods are unreliable for positive identification although the landmark‐only method could be useful for exclusion.     

The future of online social work education and Title IV-E child welfare stipends

ABSTRACT

In this concept paper, the authors explore online learning in social work and how IV-E education has been and will continue to be impacted. An empirical estimate of the national prevalence of online IV-E social work degree options is presented. Using Colorado as a case example, the authors share some of the opportunities and challenges presented by online education. Universities in Colorado have realized that online education connects rural and indigenous communities, reduces the need for students to relocate, and promotes a well-prepared, qualified child welfare workforce, but online options also challenge programs with localization issues. With connectivity increased and the physical location of students becoming less and less relevant, IV-E child welfare education providers need a proactive national dialogue to further assess the benefits and barriers to IV-E partnerships across state lines and the development of promising approaches in this area. The recruitment and retention of a well-educated and prepared child welfare workforce is critical for positive outcomes for children and families. Online social work education continues to grow nationwide. Now is the time for a national workgroup, including a broad group of stakeholders, to explore how the IV-E community will respond to online delivery of social work education.
