Economics of boar taint prevention without surgical castration in the pork chain

An economic analyses of boar taint prevention without surgical castration is lacking. This paper explores currently feasible alternatives to surgical castration along the pork chain. The considered alternatives include genetic selection (pig breeding stage); altering management strategies (pig growing stage); slaughter at younger age and lower weight (slaughtering stage). Control measures relevant to these alternatives were designed and examined, using costeffectiveness and cost-benefit analysis. Results show that the option of single-sex raising of entire males is more cost-effective compared to the mixed-sex option. The breeding programs combining selection on boar taint and economics are more cost-effective than programs focusing on boar taint only, and also much more cost-effective than slaughtering at a younger age and lower weigh

Interference Errors in the Speech of Hispanic Students Learning Russian Language as Foreign

В современном мире знание иностранных языков становится все более востребованным, поэтому перед методистами и преподавателями стоит задача найти способы эффективного обучения иностранному языку, в том числе русскому языку. По мнению автора, сделать этот процесс более продуктивным позволит анализ и классификация ошибок студентов-иностранцев. Цель статьи – описать и охарактеризовать типичные лексико-семантические и грамматические ошибки испаноязычных учащихся в русской речи, возникающие вследствие межъязыковой интерференции, а также представить способы их предупреждения и преодоления. Автор пришел к выводу о том, что наиболее распространенными интерференционными ошибками являются: 1) прямой лексический перенос; 2) неправильный выбор эквивалента, когда испанской лексеме соответствует два коррелята в русском языке; 3) ошибки в управлении; 4) нарушение согласования и сочетаемости слов; 5) искажение грамматической модели вследствие дословного перевода с родного языка на изучаемый язык. По мнению автора, результаты исследования можно использовать при создании национально-ориентированных тестов и учебников по русскому языку как иностранному.In the modern world the knowledge of foreign languages is becoming necessary, therefore, methodologists and teachers face a serious task of finding the effective ways of teaching foreign languages including Russian language. In the author's opinion, the process of teaching Russian language will be more productive when analyzing and classifying errors of foreign students. The purpose of the article is to describe and analyze the typical lexico-semantic and grammatical errors of Hispanic students in Russian speech, caused by cross-language interference and also to present ways of their preventing and overcoming. The author came to the conclusion that the most common interference errors are: 1) direct lexical transfer; 2) incorrect selection of the equivalent, when Spanish lexeme has two correlates in Russian language; 3) errors of words coordination; 4) errors of matching and compatibility of words; 5) distortion of the grammatical model due to a literal translation from the native language to the studied language. In our opinion the results of the research can be used in creation nationally-oriented tests and textbooks on Russian as a foreign language

Development of attention in graders

© Medwell Journals, 2015. Objective of this study is a theoretical substantiation and experimental approbation of forms and methods of attention development in graders. The experiment involved 100 pupils from Kazan Secondary General Education School. We have collected information using two variants of tests for determining the scope and level of attention as well as mathematical statistics methods, t-Student test to verify hypotheses about the significance of difference in the averages. The ascertaining experiment results have shown that most test subjects have a low level of attention. After the formative experiment using psychological and educational attention development program "Most Attentive" the graders have shown a significant increase in their attention level. The performed pedagogical experiment has proved the correctness of the hypothesis and theoretical provisions for the implementation of the defined pedagogical conditions for developing the attention in graders

How Relations are Built within a SNS World: Social Network Analysis on Mixi

Our purpose here is to (1) investigate the structure of the personal networks developed on mixi, a Japanese social networking service (SNS), and (2) to consider the governing mechanism which guides participants of a SNS to form an aggregate network. Our findings are as follows:the clustering coefficient of the network is as high as 0.33 while the characteristic path lenght is as low as 5.5. A network among central users (over 300 edges) consist of two cliques, which seems to be very fragile. Community-affiliation network suggests there are several easy-entry communities which later lead users to more high-entry, unique-theme communities. The analysis on connectedness within a community reveals the importance of real-world interaction. Lastly, we depict a probable image of the entire ecology on mixi among users and communities, which contributes broadly to social systems on the Web

Periods of academic mobility development in Russia

© 2016 Shakirova & Valeeva.Every year the number of students participating in the mobility programs grows rapidly. This is the main reason of the scientific interest to the problem of academic mobility. In spite of the fact that academic mobility has recently become the subject of study of many researchers, the phenomenon of academic mobility is not a new one. By present time some Russian and foreign researchers have devoted their studies to the problem of the academic mobility periodization. However, most of them cover mostly the XX and XXI centuries. Nevertheless, it does not mean that academic mobility had not existed before that period. Some researchers support the opinion that the beginnings of academic mobility can be found in the Medieval Times. There is a small amount of scientific works devoted to the problem of academic mobility periodization. The analysis of these works is of great importance, as there is no universal variant of academic mobility periodization
