Understanding adolescent mental health symptom progression in school-based settings: The Substance Use and Risk Factors (SURF) longitudinal survey.

The adolescent mental health crisis has prompted a need for an improved understanding of developmental trajectories of psychopathology to promote understanding of risk and protective factors and bolster prevention and intervention efforts. The present study describes the Substance Use and Risk Factors Survey, a universal screener of mental health, substance use, and school and contextual factors administered in public middle and high schools in Massachusetts (₂₀₂₀ = 3,522, ₂₀₂₁ = 6,484, ₂₀₂₂ = 23,915). Using a seven-question linking code approach, a subset of students were longitudinally linked across administrations ( = 563, 58% female sex, 30.

Intention to quit or reduce e-cigarettes, cannabis, and their co-use among a school-based sample of adolescents.

Introduction: Little is known about the prevalence and predictors of adolescents' intention to quit or reduce use of e-cigarettes and/or cannabis.

Methods: Frequencies of intention to change (quit, reduce) e-cigarettes and/or cannabis use were examined among 23,915 surveyed middle and high school students with sole and co-use. Predictors of intention to change were identified via LASSO/multilevel logistic regression.

Foraging Activity of Honey Bees (Apis mellifera L., 1758) and Exposure to Cadmium: a Review.

Honey bees are commonly exposed to a broad spectrum of xenobiotics, including heavy metals. Heavy metal toxicity is of concern in the context of global pollinator declines, especially since honey bees seem to be particularly susceptible to xenobiotics in general. Here we summarize current knowledge on the interplay between cadmium, one of the most toxic and mobile elements in the environment, and honey bees, the primary managed pollinator species worldwide.

Light-Induced Charge Separation in Covalently Linked BODIPY-Quinone-Alkyne Dyads.

Visible light-induced charge separation and directional charge transfer are cornerstones for artificial photosynthesis and the generation of solar fuels. Here, we report synthetic access to a series of noble metal-free donor-acceptor dyads based on bodipy light-absorbers and redox-active quinone/anthraquinone charge storage sites. Peripheral functionalization of the quinone/anthraquinone units with alkynes primes the dyads for integration into a range of light-harvesting systems, e.

Contingency management is associated with positive changes in attitudes and reductions in cannabis use even after discontinuation of incentives among non-treatment seeking youth.

Background: It is important to identify interventions that reduce harm in youth not motivated to change their cannabis use. This study evaluated how short-duration contingency management (CM) impacts cannabis use attitudes and behavior after abstinence incentives are discontinued among non-treatment seeking youth.

Methods: Participants (N=220) were randomized to 4 weeks of abstinence-based CM (CB-Abst; n=126) or monitoring (CB-Mon; n=94).
