Laboratory research in adults indicates that alcohol-related subjective effects are enhanced under some social conditions. However, it is unknown whether this "social facilitation" of alcohol effects occurs in adolescents and is associated with alcohol use in the natural ecology.We examined associations of social facilitation of alcohol-related subjective effects with subsequent alcohol use among a relatively high-risk group of adolescents who reported drinking alcohol both with friends and alone.Los Angeles high school students from a prospective study (N = 142; 51% female; 10th graders) completed a baseline survey that assessed alcohol-related "positive" and "negative" subjective effects in two contexts: social (alcohol with friends) and solitary (alcohol alone); social facilitation was calculated as the difference between social and solitary. Students then completed five semi-annual surveys spanning 30 months (2014-2017) assessing 30-day alcohol use (days used, number of drinks, binge drinking).Greater social facilitation of positive effects was significantly associated with greater number of alcohol use days (RR [95% CI] = 1.48 [1.19, 1.82]; p < .001), greater number of drinks (RR [95% CI] = 1.38 [1.14, 1.66]; p = .001), and greater odds of binge drinking (OR [95% CI] = 1.75 [1.20, 2.57]; p = .004). Similar associations were found with social positive effects. There were no significant associations between solitary positive effects-or any negative effects-and alcohol use outcomes.Social facilitation can be measured outside of the laboratory. Relatively high-risk drinking adolescents who are more susceptible to the social facilitation of subjective alcohol effects are more likely to use more alcohol and binge drink.

To support the development of a society that is attuned to the challenges presented by sustainable development, it is vital that higher education business students understand the value of sustainability, and act in a way that is consistent with these values. This paper explores a sustainability-focused experiential learning activity through investigating the utility of an emerging form of service learning in the digital space for developing global citizens. The paper presents an international case study of educators who employed digital service learning in various business education contexts. The research reports on the perceptions of higher education students in relation to their awareness, critical thinking and action for sustainability. The paper has practical contributions in identifying an opportunity for implementing sustainability curriculum into higher education for business.

It would be very beneficial to determine in advance whether a student is likely to succeed or fail within a particular learning area, and it is hypothesized that this can be accomplished by examining student patterns based on the data generated before the learning process begins. Therefore, this article examines the sustainability of data-mining techniques used to predict learning outcomes. Data regarding students’ educational backgrounds and learning processes are analyzed by examining their learning patterns. When such achievement-level patterns are identified, teachers can provide the students with proactive feedback and guidance to help prevent failure. As a practical application, this study investigates students’ perceptions of computer and internet use and predicts their levels of information and communication technology literacy in advance via sustainability-in-data-mining techniques. The technique employed herein applies OneR, J48, bagging, random forest, multilayer perceptron, and sequential minimal optimization (SMO) algorithms. The highest early prediction result of approximately 69% accuracy was yielded for the SMO algorithm when using 47 attributes. Overall, via data-mining techniques, these results will aid the identification of students facing risks early on during the learning process, as well as the creation of customized learning and educational strategies for each of these students.

Positive and strong relationships among various stakeholders are essential for the sustainable management of an organization. Despite growing interest in how various sport organizations manage stakeholders to promote social sustainability, there remains a gap in stakeholder and sustainability research in high school athletics. The purpose of this study was to examine how the social sustainability of sport organizations (i.e., high school athletics) were maintained during decision-making processes. Specifically, this study used a qualitative case study framed by stakeholder theory to investigate how the relevant decision-makers in high school athletics (i.e., principals and athletic directors) manage other stakeholders in their departmental decision-making processes to promote the sustainability of their athletic department. Two high schools from the US and South Korea, one from each country, were selected as the cases for the current study. Semi-structured interviews regarding stakeholder management in departmental decision-making processes were conducted with four individual interviewees, including the principals and athletic directors of each high school. The results of this study illustrated that both the US and the South Korean high school athletic departments utilized stakeholder engagement strategy in their departmental decision-making processes. The principals and athletic directors recognized the importance of communicating with other stakeholders and engaging them in athletic department decisions. Specifically, the organizational decisions of both high school athletic departments were made in consultation with the main internal stakeholders of the athletic department (i.e., the principal and athletic director) as well as other various stakeholders (e.g., parents, coaches, alumni association).

South Korean universities have been facing student shortages to sustain their growth due to its severe population decline. The Korean government has since introduced policies to attract more international students to the country. The present study examined the prestige-seeking tendencies of international students in Korea and their influence on students’ satisfaction levels. The five dimensions of prestige-seeking behavior were adopted to help explain students’ satisfaction levels. Research samples were current and former international students in Korea. The findings reveal the quality of the education did not contribute directly to the students’ overall satisfaction level. Instead, it was hedonic elements that affected satisfaction. Moreover, status, snob, and bandwagon effects contributed significantly to the quality and hedonic motives.

The job shop scheduling problem is one of the well-known hardest combinatorial optimization problems, and solving the problem can be complex and time-consuming task. Hence, many undergraduates can not fully experience the scheduling procedures. This paper aims to introduce a computer game designed to enable the players to create and solve the job shop scheduling problems, and the players can learn the topics such as scheduling and optimization via a sense-making experiences provided by the game playing. The game program provides a simple graphic user interface similar with traditional board games played by manipulating blocks, and the players can conveniently search the good schedules in a trial-and-er ror manner. Moreover, the completed schedules are evaluated by taking the schedules generated by the genetic algorithm into account. For reasonable evaluation, the game program adopts two search strategies called forward and backward search to generate schedules with a wide range of makespans. The integrated job shop scheduling game introduced is well-organized to support overall procedures for job shop scheduling, and the genetic algorithm based evaluation can make the players to compete for better schedules. As a result, both purposes, entertainment and education, can be simultaneously served by the game playing.

Before COVID-19, online learning in higher education was more of a choice than a requirement. The majority of universities in South Korea are currently not utilizing an evaluation index tailored specifically to online courses and are instead using the traditional in-person class evaluation standards. The study, hence, examines the factors that could be used to evaluate the quality of online learning in higher education taking place due to the COVID-19 pandemic from the point of views of the main subjects of online education: e-learning system administrators, instructors, and students. The analytical hierarchy process (AHP) method was used to determine the relative importance of factors in evaluating online learning. The conclusions derived from this research can be used as foundational material for evaluation factors of online learning in higher education.

Abstract A search in energetic, high-multiplicity final states for evidence of physics beyond the standard model, such as black holes, string balls, and electroweak sphalerons, is presented. The data sample corresponds to an integrated luminosity of 35.9 fb−1 collected with the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV in 2016. Standard model backgrounds, dominated by multijet production, are determined from control regions in data without any reliance on simulation. No evidence for excesses above the predicted background is observed. Model-independent 95% confidence level upper limits on the cross section of beyond the standard model signals in these final states are set and further interpreted in terms of limits on semiclassical black hole, string ball, and sphaleron production. In the context of models with large extra dimensions, semiclassical black holes with minimum masses as high as 10.1 TeV and string balls with masses as high as 9.5 TeV are excluded by this search. Results of the first dedicated search for electroweak sphalerons are presented. An upper limit of 0.021 is set at 95% confidence level on the fraction of all quark-quark interactions above the nominal threshold energy of 9 TeV resulting in the sphaleron transition.
