Enlisting Peer Cooperation in the Service of Alcohol Use Prevention in Middle School

This article reports on a cluster randomized trial of cooperative learning (CL) as a way to prevent escalation in alcohol use during middle school (N = 1,460 seventh‐grade students, age 12–13, seven intervention and eight control schools). We hypothesized that CL, by bringing students together in group‐based learning activities using positive interdependence, would interrupt the process of deviant peer clustering, provide at‐risk youth with prosocial influences, and in turn, reduce escalations in alcohol use. Results indicated that CL significantly reduced growth in deviant peer affiliation and actual alcohol use, and effects for willingness to use alcohol were at the threshold of significance (p = .05). CL also attenuated the link between willingness to use alcohol and later alcohol use.

MPs are demanding a 5p levy on bottles of wine to pay for treating problem drinkers and alcoholics. Increasing alcohol duty by 1% could raise £100million a year and save the NHS money, it is claimed.

We reported the organic template-free synthesis of gold (Au) nanoparticles (NPs) supported on TiO2, SiO2, and Al2O3 displaying uniform Au sizes and high dispersions over the supports. The Au-based catalysts were prepared by a deposition –precipitation method using urea as the precipitating agent. In the next step, the solvent-free oxidation of benzyl alcohol was investigated as model reaction using only 0.08–0.05 mol% of Au loadings and oxygen (O2) as the oxidant. Very high catalytic performances (TOF up to 443,624  h−1) could be achieved. Specifically, we investigated their catalytic activities...

ConclusionsThe disease burden of MHE is quite substantial in patients with cirrhosis with no apparent cognitive defect. Smoking, whether past or current, has significant association with the presence of MHE. Though MHE has been shown to adversely affect quality of life, prophylaxis for MHE is not routinely practiced in the Indian setting.The study has been registered under clinical trials registry of India (CTRI/2014/01/004306).

AbstractA procedure for preparation of99Mo/99mTc radioisotope generator based on low specific activity neutron activated99Mo was developed. Aluminum molybdate(VI)-99Mo of high Mo(VI) content (~  364 mg/g Al99Mo) was prepared by mixing low specific activity molybdate(VI)-99Mo and aluminum mixture solution with isoamyl alcohol. Al99Mo gel matrix was precipitated when the pH of the mixture solution was raised to ~  5 by addition of NaOH to the mixture. Radiometric measurements indicate the strong fixation of Molybdate(VI)-99Mo species in the form of the sparingly insoluble Al99Mo gel matrix. The prepared Al...

Beer is the prom king of alcoholic beverages, winning the popularity contest in terms of total volumes drunk. And because its main ingredient, barley, is sensitive to extreme drought and heat, climate change will cause undue pain for all who love their lager, new research suggests.

Publication date: Available online 15 October 2018Source: Chinese Journal of Chemical EngineeringAuthor(s): Chunli Li, Cong Duan, Jing Fang, Hongshi LiAbstractReactive distillation (RD) process is an innovative hybrid process combining reaction with distillation, which has recently come into sharp focus as a successful case of process intensification. Considered as the most representative case of process intensification, it has been applied for many productions, especially for production of ester compounds. However, such problems existing in the RD system for ester productions are still hard to solve, as the removal of the...

In this study, we present a water-based grafting approach to produce polyvinyl alcohol (PVA) incorporated CNT buckypaper and CNT-graphene hybrid buckypaper composites with enhanced mechanical performance (tensile and fracture) and electrical conductivity. Our approach provides a wide range of composition for CNT (5–77 wt.%) and polymer matrix (23–95 wt.%) without compromising the uniformity of CNT dispersion and polymer matrix homogeneity. The composite buckypapers have lightweight with a density of 168 mg/cc (lighter than daily use copy papers having a density of 740 mg/cc). They show an electrical conduct...
