Exploratory analyses were used to identify a unique constellation of variables that are associated with marijuana use outcomes among college students. We used recursive partitioning to examine more than 100 putative antecedents of lifetime marijuana user status, past-month marijuana user status, and negative marijuana-related consequences. Participants ( N = 8,141) completed measures online across 11 sites in the United States. Norms (descriptive, injunctive, and internalized norms) and marijuana identity best distinguished marijuana users from nonusers (i.e., lifetime/past month), whereas marijuana use frequency, use of protective behavioral strategies, and positive/negative urgency best distinguished the degree to which users reported negative consequences. Our results demonstrate that tree-based modeling is a useful methodological tool in the selection of targets for future clinical research. Additional research is needed to determine if these factors are causal antecedents, rather than consequences or epiphenomena. We hope this large sample study provides the impetus to develop intervention strategies targeting these factors.

There is increasing evidence that mental health problems may attenuate the relationship between protective behavioral strategies (PBS) and alcohol outcomes. However, psychological distress may also affect these relationships. Further, it appears that different types of PBS have differential relationships with alcohol outcomes. The current study examined the degree to which psychological distress moderated the associations PBS subtypes had with hazardous drinking and alcohol-related negative consequences. Participants were 632 traditional-age undergraduate students ( M = 20.04, standard deviation = 1.48) who had consumed alcohol within the past 30 days and completed online self-report measures designed to assess PBS use, level of psychological distress, hazardous drinking patterns, and alcohol-related negative consequences. Serious harm reduction PBS were associated with less hazardous drinking and less alcohol-related negative consequences, and these associations were strengthened for those experiencing greater psychological distress. Controlled consumption PBS were associated with less hazardous drinking, but this association was not moderated by psychological distress. These findings highlight the potential benefit of teaching serious harm reduction PBS to college students experiencing elevated levels of psychological distress.

Academic dishonesty (AD) continues to be of great concern in higher education (HE). In this chapter, the authors review literature in this area, with a particular emphasis on preventive interventions. In recent years, with the dramatic increase of international students in HE, the authors also address how cultural diversity may further complicate this issue. A current study of cheating behaviors is discussed comparing a sample of undergraduate college students from the United States (US) with a sample of undergraduate college students from China. With reference to those results, the authors then propose intervention strategies for reducing AD based on the literature and results of this comparative study.

The article is devoted to the analysis of the formation of the legal framework that made possible the existence and functioning of the US foreign service. The purpose of the article is to clarify the preface and the course of formation of the professional foreign service of the United States, which was reflected in the adoption of the Rogers Act. The methodological basis of the study. The study was based on the principle of historicism, which contributed to the consideration of the phenomenon under study in its development and made it possible to identify periods in the formation of a professional diplomatic service. The use of the problem-chronological method contributed to the preservation of the historical heredity and integrity of the picture; the application of the comparative method made it possible to identify significant changes that occurred after the adoption of Rogers’ Law, which was considered through the use of the method of analysis. A historiographical description of the main scientific works devoted to the research topic is given. Analyzed works A. Evans, T. Lay, I. Stewart etc., which became the basis for the study. The scientific novelty lies in the systematization of ideas about qualitative and quantitative changes in the diplomatic service after the adoption of the relevant law. The author concludes that before the adoption of the Rogers Act there was no control over the selection of diplomatic and consular staff and the negative consequences of such a decision were especially evident during the First World War. Therefore, the historical conditions in which America found itself at that time became a challenge for the continued existence of the consular and diplomatic services, and therefore the issue of restructuring and modernization of these services in the United States and its transfer to another, qualitatively new level. In general, the author emphasizes the change in the status of foreign service, which was introduced by relevant legislation, namely the Rogers Act, the need for which was caused by certain historical conditions of the American state and its place on the world stage. Prior to the enactment of the Diplomatic Service Act, there was virtually no control over the selection of diplomatic and consular personnel representing the United States on the world stage. After the First World War, it became clear that the diplomatic service needed to be restructured. That is why Rogers’ law was passed, which, in fact, was the first legislative attempt to resolve this issue.

This research is the result of a qualitative study that explored the ways in which marijuana using mothers come to identify as such and how they structure their relationships and parenting as a result. The experiences of 57 self-identified marijuana using mothers (aged 20-48 years-old) from across the United States participated in semi-structured interviews and shared their everyday experiences with both marijuana use and motherhood. Participants were all mothers with children between 3 months and 19 years at the time of the interviews. A thematic narrative analysis uncovered common experiences among these women in constructing both individual and group identity: Participants varied in how each of these themes identified were reflected in their lives, depending upon each participant's interpretation of her local social context. Both motherhood and self-identifying as a marijuana user were valuable and meaningful parts of their identity

Aims: Marijuana is a popular drug among U.S. college students. In Sweden, the prevalence of marijuana use has been relatively low but is increasing. Brief, personalized interventions have been efficacious in reducing substance use, including marijuana, among college students in the U.S. However, prior to implementation of U.S. interventions in Sweden, it is important to compare factors associated with marijuana use among college students in the two countries. Design, Setting, and Participants: Data are from baseline assessments of two large college student intervention studies in the U.S. (N = 3,753, 39% male) and Sweden (N = 2,280, 35% male). Measures: Past 30-day prevalence and frequency of marijuana use was analyzed in regard to relevant demographic factors. The moderating role of nationality was also examined. Findings: Results support previous findings indicating marijuana use is more common in the U.S. than in Sweden. Most demographic factors were similar across the countries, except for relationship status and work status, in which associations with number of marijuana use days (but not odds of any marijuana use) were stronger for Swedish college students compared to U.S. college students. Conclusions: Based on overall similarities between the U.S. and Sweden, comparable interventions might be recommended in both countries.
