Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

American Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

Open Latarjet Procedure Using Double Suture‐Button Fixation

Arthroscopy Techniques, EarlyView.
Abstract The Latarjet procedure is the most commonly used technique for recurrent anterior instability with significant bone loss. However, the screws used to fix the coracoid are the major risk for postoperative complications including screw penetration and glenoid articular cartilage damage, prominence and impingement of the screw head onto the ...

DeCoTa: a lightweight decentralized cross-chain transfer scheme based on hash-locking

Scientific Reports
With the wide application of blockchain comes the challenge of cross-chain interaction. For example, the isolation between the information stored in different blockchains can result in the ”isolated islands of value” effect in blockchains.
