https://www.selleckchem.com/products/stemRegenin-1.html The aim of this study was to examine whether three theories of adolescent substance use-social learning, social bonding, and self-control-were useful for predicting adolescent nicotine vaping. The analysis utilized data on U.S. 8th and 10th grade students from the 2017 and 2018 Monitoring the Future (MTF) studies, repeated cross-sectional surveys that included 11,624 youth who responded to questions about past 12-month nicotine vaping. Measures from each of the three theories were used to predict the outcome using a zero-inflated negative binomial model. The results demonstrated that variables from social learning and self-control theories were key predictors of nicotine vaping. Friends' substance use appeared as the most consequential predictor, followed by low self-control or higher risk-taking propensities. An interaction effect also suggested that friends' substance use had a stronger association with nicotine vaping among youth who reported higher self-control. The findings suggested that adol also suggested that friends' substance use had a stronger association with nicotine vaping among youth who reported higher self-control. Conclusions/Importance The findings suggested that adolescent nicotine vaping is a consequence of social learning influences and low self-control. Future research should explore these and similar factors in more detail.Objectives. The purpose of this study was to determine the factors that university music students and professional musicians believe caused their musculoskeletal symptoms (MSSs). Methods. Data were collected using a questionnaire distributed to university music students and professional musicians. Using a musician-driven data collection approach, musicians with MSSs were asked to nominate their top three perceived causes of their symptoms. Responses were categorized, and percentages reported for the main categories. Results. Of the 213 musicians, 37.6% reported biolog
