Although industry self-regulation has developed into a preferred regulatory strategy for the digital economy, self-regulatory solutions adopted in the U.S. and the European Union differ considerably. We argue that variation in the shadow of public power—the public sector tools employed to induce industry collective action—sets the two on distinct self-regulatory trajectories. Legalistic self-regulation dominates in the U.S. and coordinated self-regulation in Europe. Expectations derived from the model are evaluated in case studies of online content regulation and personal data privacy protection. 相似文献

Purpose
The purpose of this study is to propose a mediational model for the mechanisms through which a diagnosis of Attention-Deficit/Hyperactivity Disorder between the ages of 10 and 12 predicts positive and negative early adult outcomes for African Americans.Methods
The study sample (n = 211) was drawn from the Des Moines, Iowa subsample of the Family and Community Health Study. Participants were first assessed between the ages of 10 and 12, again between the ages of 12 and 18, and finally at 18 to 23.Results
Findings indicate that a diagnosis of ADHD before age 13 indirectly predicted subsequent exclusionary school discipline and juvenile arrest in adolescence, and both arrests and educational attainment in young adulthood.Conclusions
These findings offer support for the School to Prison Pipeline model, showing that for some African American children, a childhood diagnosis of ADHD can lead to negative school experiences that result in harsh school-based discipline, which in turn open the door to justice system involvement spanning several developmental stages. 相似文献67.

Timewise temperature variations in objects that are undergoing unsteady heating or cooling is a commonly encountered problem in the thermal sciences. One particular area of application is the cooling of a body post-death and the use of body temperatures to estimate the time of death. Here, a new approach based on the theory of transient heat transfer is formulated to allow efficient calculation of unsteady conduction problems. The theoretically derived unsteady temperature models are compared with experimentally based correlations (the Marshall-Hoare-Henssge model). The two approaches are found to agree very well. With this new theoretically based approach, timewise temperature variation can be calculated for both large and small Biot number transient problems. 相似文献

Anthea B. Mahesan Paul M.D. M.Sc. Lary Simms D.O. M.Sc. Saeideh Amini B.Sc. M.Sc. Abraham Ebenezer Paul M.D. 《Journal of forensic sciences》2018,63(4):1321-1324
Synthetic cannabinoids (SCs) are commonly abused by adolescents with reported past year (2013) use in high school students between 3 and 10%. Standard adolescent postmortem toxicology does not include routine SC analysis, and thus, the true burden of fatalities related to SCs is unknown. A retrospective case review of two cases included scene investigation, interviews, autopsy, and toxicology. SCs were confirmed by liquid chromatography–tandem mass spectrometry (LC?MS/MS). Review of the eight adolescent SC‐associated fatalities in the literature revealed five of eight cases had no other discernible cause of death on autopsy. Compounds detected included PB‐22 (1.1 ng/mL), JWH‐210 (12 ng/mL), XLR‐11 (1.3 ng/mL), JWH‐122, AB‐CHMINACA (8.2 ng/mL), UR‐144 (12.3 ng/mL), and JWH‐022 (3 ng/mL). With synthetic drug use on the rise, forensic experts should have a high index of suspicion for the possibility of SC intoxication in adolescent fatalities with no other discernible cause of death. 相似文献
