Is diversity good or bad? Evidence from eSports teams analysis
We use eSports data to construct an empirical model to measure the effect of diversity on team performance. Different kinds of diversities are considered, diversity of culture, diversity of language and diversity of skill. Our main results are that cultural diversity is beneficial for team performance: the absence of diversity reduces performance by 30%. However, language and experience diversity negatively affect results. Taking the difference in the results into account, we conclude that firms should not thoughtlessly maximize team diversity: different kinds of diversity have different integration and communication costs.
"How can psychology professors in the USA and other nations make their courses more international?" This question is addressed in this indispensable new sourcebook, co-authored by 73 contributors and editors from 21 countries. In recent decades psychology has evolved from an American-dominated discipline to a much more global discipline. Preliminary estimates by Zoma and Gielen (2015) suggest that approximately 76%-78% of the world’s one million or so psychologists reside outside the U.S. However, most textbooks in the field continue to rely predominantly on research conducted in North America and Europe. Our book is intended to introduce psychology instructors to a variety of broad perspectives as well as specific suggestions that can support their efforts to internationalize their course offerings at both the undergraduate and graduate levels. In this way they can prepare their students to become more culturally sensitive and function more effectively as citizens and psychologists in the evolving globalized world. To achieve these ambitious goals the editors have assembled an international group of 73 distinguished contributors who, taken together, have taught and conducted research in all regions of the world. The chapters in the book include both core areas of psychology and subdisciplines that represent rapidly expanding and internationally important areas such as cross-cultural psychology and the psychology of gender. The chapters cover key topics and areas included in the course offerings of psychology departments both in the United States and in other countries. In addition to a discussion of international perspectives relevant to a given area, all chapters include an annotated bibliography of pertinent books, articles, web-related materials, films, videos, and so on. Based on this information, both highly experienced and less experienced psychology instructors can add globally and culturally oriented dimensions to their respective courses. This is important because universities, departments, and accrediting agencies increasingly put pressure on instructors to broaden and internationalize their courses.
In this paper we suggest the first systematic review and com- pare performance of most frequently used machine learning algorithms for prediction of the match winner from the teams’ drafts in DotA 2 computer game. Although previous research attempted this task with simple models, weve made several improvements in our approach aiming to take into account interactions among heroes in the draft. For that pur- pose we’ve tested the following machine learning algorithms: Naive Bayes classifier, Logistic Regression and Gradient Boosted Decision Trees. We also introduced Factorization Machines for that task and got our best re- sults from them. Besides that, we found that model’s prediction accuracy depends on skill level of the players. We’ve prepared publicly available dataset which takes into account shortcomings of data used in previous research and can be used further for algorithms development, testing and benchmarking.
Students studying a foreign language find themselves involved into the dialogue between their own culture and that one of the target language. To perform successfully cross-cultural communication they need to develop cross-cultural competence. The task of a foreign language teacher is to help them acquire necessary skills. The article addresses the issue of using fictional discourse as a valuable source to teach cultural diversity as cultural patterns, concepts, symbols and stereotypes are acquired through texts of a particular culture, literary works playing a significant role among them. The focus is on certain comprehensive analysis techniques (linguo-stylistic, conceptual and culturological) of figures of speech, metonymy in particular, which can be applied to decode implicit cultural codes.
Big History has been developing very fast indeed. We are currently observing a ‘Cambrian explosion’ in terms of its popularity and diffusion. Big History courses are taught in the schools and universities of several dozen countries, including China, Korea, the Netherlands, the USA, India, Russia, Japan, Australia, Great Britain, Germany, and many more. The International Big History Association (IBHA) is gaining momentum in its projects and membership. Conferences are beginning to be held regularly (this edited volume has been prepared on the basis of the proceedings of the International Big History Association Inaugural Conference [see below for details]). Hundreds of researchers are involved in studying and teaching Big History.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
