The research evaluated the
efficacy of an intervention to reduce the onset and extent of binge drinking during the 1st
year of college. The approach was on influencing the students before they start ...college,
through their parents, during the critical time between high school graduation and the
beginning of college. Specifically, parents were educated about binge drinking and how to
convey information to their teens, and then encouraged to talk with their teens just before
their teens embarked on their college education. Teens whose parents implemented the
intervention materials were compared with a control sample during their 1st semester on
drinking outcomes, perceptions about drinking activities, perceived parental and peer approval
of drinking, and drinking-related consequences. As anticipated, teens in the treatment
condition were significantly different (
p
< .05) on nearly all outcomes
in the predicted directions (e.g., lower drinking tendencies, drinking consequences). The
benefits of a parent-based intervention to prevent college drinking are discussed.
The present research contrasted theoretical models depicting the nature of the relation among drinking beliefs, drinking tendencies, and behavioral consequences in 266 incoming freshman college ...students. It also examined the theoretical relations between mother-teen communications and drinking beliefs relevant to behavioral consequences. The findings revealed direct relations between binge-drinking consequences and the drinking beliefs: Alcohol can make positive transformations, can enhance social behavior, and can increase negative affect and normative approval. Direct relations were not observed between consequences and the drinking beliefs regarding physical risk and health orientation. Finally, the present research found consistent support for the relation between mother-teen communications and drinking beliefs relevant to binge-drinking consequences.
The current study is a multisite randomized alcohol prevention trial to evaluate the efficacy of both a parenting handbook intervention and the Brief Alcohol Screening and Intervention for College ...Students (BASICS) intervention, alone and in combination, in reducing alcohol use and consequences among a high-risk population of matriculating college students (i.e., former high school athletes).
Students (n = 1,275) completed a series of Web-administered measures at baseline (in the summer before starting college) and follow-up (after 10 months). Students were randomized to one of four conditions: parent intervention only, BASICS only, combined (parent and BASICS), and assessment-only control. Intervention efficacy was tested on a number of outcome measures, including peak blood alcohol concentration, weekly and weekend drinking, and negative consequences. Hypothesized mediators and moderators of intervention effect were tested.
The overall results revealed that the combined-intervention group had significantly lower alcohol consumption, high-risk drinking, and consequences at 10-month follow-up, compared with the control group, with changes in descriptive and injunctive peer norms mediating intervention effects.
The findings of the present study suggest that the parent intervention delivered to students before they begin college serves to enhance the efficacy of the BASICS intervention, potentially priming students to respond to the subsequent BASICS session.
AbstractBackgroundStudies indicate older adults have increased risk for alcohol-related harms (e.g., risk for falls) that can manifest at lower levels of consumption than younger adults. ...Specifically, age-related changes in alcohol metabolism, physiology, increased morbidity, and potential interactions with medications to manage chronic conditions increases risk for related harms among older adults.PurposeThe present study used cross-sectional data to examine the associations between drinking to cope motives and positive alcohol expectancies, and injunctive drinking norms in older adults. We also explored the interaction between drinking to cope, positive expectancies and injunctive drinking norms on alcohol use.MethodsAdults aged 65 and older ( N = 98) completed a series of measures assessing drinking to cope motives, positive alcohol expectancies, injunctive drinking norms, and past-month alcohol use. ResultsPositive alcohol expectancies were positively associated with drinking to cope motives. Drinking norms were not associated with coping motives. Moderating effects of expectancies varied on the link between coping motives and alcohol use. Greater endorsement of coping motives was associated with more alcohol consumption but only for those with low expectancies.ConclusionsBetter understanding of the complex interplay between drinking to cope motives, positive expectancies, and injunctive drinking norms of proximal as well as distal referents could foster improvement of clinical assessments to screen for risk factors of alcohol abuse and promote development of more age-salient measures of alcohol expectancies, norms, and motives.

The new generation of silicon detectors for particle physics requires very reduced mass and high resistance to radiations with very limited access to the detector for maintenance. The Silicon Pixel ...Detector (SPD) is one of the 18 detectors of the ALICE (A Large Io Collider Experiment) experiment at the Large Hadron Collider (LHC) at CERN. It constitute the two innermost layers of the Inner Tracking System (ITS) and it is the closest detector to th interaction point. An evaporative cooling system, based on C4F10 evaporation at 1.9 bar, was chosen to extrac the 1.35 kW power dissipated by the on-detector electronics. The whole system wa extensively tested and commissioned before its installation inside the ALICE experimenta area. Since then we had to deal with a decrease of the flow in some lines of the system tha imposed severe restrictions on the detector operation. Recently, a test bench has been built in order to carry out a series of tests to reproduce the misbehaviour of the system and investigat proper actions to cure the problem. The performance of the systems and the most interesting results of the above mentioned test will be presented.
Among emerging adults, those who do not attain postsecondary education are at highest risk for experiencing longterm problems related to alcohol use, including alcohol dependence. The purpose of the ...current study was to identify latent classes of alcohol users among non-college-attending youth and examine correlates of class membership.
Screening criteria were used to select emerging adults between ages 18 and 22 years with no postsecondary education (N = 264) from a prerecruited probability-based Web panel. Latent class analysis (LCA) was used to identify common patterns of alcohol use. Grouping variables and demographic variables were added to the LCA model, and rates of alcohol-related consequences across the LCA classes were compared.
Four classes of drinking patterns were identified: (a) current nondrinkers (34%), (b) weekend light drinkers (38%), (c) weekend risky drinkers (23%), and (d) daily drinkers (5%). Class membership was associated with early onset of alcohol use (age 14 or younger), marital status, employment status, and urban residency (area populated by 50,000 or more people). The number of latent classes did not differ across sex and legal drinking age status, although proportions of subjects within classes varied by age. Weekend risky drinkers were most likely to report sickness and feelings of guilt because of drinking, whereas daily drinkers were most likely to report getting into fights, driving a car after drinking, and missing work.
Similar to college samples of emerging adults, most of this noncollege sample belonged to latent classes defined by rare or moderate alcohol use. Nevertheless, nearly a quarter of the sample reported high-risk drinking behaviors, and a small number reported drinking alcohol on a daily basis. Both of these classes were at elevated risk for experiencing a number of alcohol-related consequences.
Particle identification techniques are fundamental tools in nuclear physics experiments. Discriminating particles or nuclei produced in nuclear interactions allows to better understand the underlying ...physics mechanisms. The energy interval of these reactions is very broad, from sub-eV up to TeV. For this reason, many different identification approaches have been developed, often combining two or more observables. This paper reviews several of these techniques with emphasis on the expertise gained within the current nuclear physics scientific program of the Italian Istituto Nazionale di Fisica Nucleare (INFN).
