Reduction Of Uncertainty

With data collected from a directed social trading network, this paper investigates how social interaction affects the disposition effect. We constantly observe a negative association between them: After being exposed to social interaction, a trader’s odds ratio to sell a paper gain stock decreases by 9% to 10%, depending on different model settings. We then test the mechanisms of social interaction by decomposing it into three channels: learning intensity (willingness to learn), learning quality (information advantage through learning), and public scrutinization (exposure of trading outcome to others). We find that all three channels contribute to a smaller disposition effect. Specifically, our findings support the claim that public scrutinization promotes self-consciousness and reduces disposition effect. Also, our results extend previous studies on investors’ information advantage by suggesting that it could also help to mitigate the disposition effect through the reduction of uncertainty. Overall, this paper suggests a positive role of social trading platforms in helping investors make better decisions.

Описывается эмпирическое исследование педагогических механизмов формирования компетенции социального взаимодействия у студентов управленческого вуза на занятиях по физической культуре. Рассматриваются результаты изучения отношений «преподаватель-студент», была осуществлена оценка эффективности деятельности преподавателя физической культуры, а также произведено распределение студентов по уровню формирования компетенции социального взаимодействия. Выявлено наличие факторов у студентов, имеющих низкий и высокий уровень формирования компетенции социального взаимодействия в зависимости от пола и курса обучения. Представлены результаты диагностики межличностных отношений студентов управленческого вуза в зависимости от пола и теста-опросника социальной адаптивности в зависимости от курса (I– II). Методы исследования. В исследовании применяются такие методы, как педагогическое наблюдение; анкетирование; психолого-педагогические методики: личностный опросник Р. Кеттелла, методика диагностики межличностных отношений (Т. Лири), тест-опросник социальной адаптивности (А. Санникова, А. Кузнецова). Результаты. В процессе проведения исследований было выявлено, что большинство студентов управленческого вуза рассматривают положительную роль преподавателя при формировании у них компетенции социального взаимодействия. Также исследованы студенты с высоким и низким уровнем формирования компетенции к социальному взаимодействию, что раскрывается через особенности адаптивности, межличностных отношений и свойств личности. Заключение. На основании результатов проведенного эмпирического исследования возникает вопрос о повышении уровня формирования компетенции социального взаимодействия у студентов управленческого вуза, что является объектом изучения нашей дальнейшей работы. The article describes an empirical study of pedagogical mechanisms of formation of competence of social interaction among students of management University in the classroom for physical culture. The results of the study of inter-relations "teacher-student", an assessment of the effectiveness of the teacher of physical culture was carried out, as well as the distribution of students according to the level of formation of competence of social interaction. The presence of factors at students with low and high level of formation of competence of social interaction depending on gender and course of the study is revealed. The results of diagnostics of students’ interpersonal relations at management University depending on sex and the test questionnaire of social adaptability depending on a course (I-II) are presented. Research methods. In the article the following methods are used: pedagogical observation; questioning; psychological and pedagogical methods: personal questionnaire R. Cattell 16-РF, methods of diagnosing interpersonal relations (T. Liri), test questionnaire of social adaptability (A. Sannikova, A. Kuznetsova). Results. In the process of conducting the research, it was revealed that the majority of students at a management university consider the positive role of a teacher in the formation of their competence of social interaction. The study of students with high and low levels of competence formation for social interaction is also presented, which is revealed through the features of adaptability, interpersonal relations and personality traits. Conclusion. On the basis of the results of the conducted empirical research, the question arises about increasing the level of formation of the competence of social interaction among students of a management university, which is the object of study of our further work.

Measure Sense

Abstract. The present study aimed at evaluating if the three-item sense of coherence (SOC) scale developed by Lundberg and Nystrom Peck (1995) can be effectively used for research purpose in both nonclinical and clinical samples. To provide evidence that it represents adequately the measured construct we tested its validity in a nonclinical (N = 658) and clinical sample (N = 764 patients with cancer). Results obtained in the nonclinical sample attested a positive relation of SOC – as measured by the three-item SOC scale – with Antonovsky’s 13-item and 29-item SOC scales (convergent validity), and with dispositional optimism, sense of mastery, anxiety, and depression symptoms (concurrent validity). Results obtained in the clinical sample confirmed the criterion validity of the scale attesting the positive role of SOC – as measured by the three-item SOC scale – on the person’s capacity to respond to illness and treatment. The current study provides evidence that the three-item SOC scale is a valid, low-loading, and time-saving instrument for research purposes on large sample.

Synthesis Procedure

: In the present study, SAPO-34 particles were synthesized using hydrothermal (HT) and dry gel (DG) conversion methods in the presence of diethyl amine (DEA) as an organic structure directing agent (SDA). Carbon nanotubes (CNT) were used as hard template in the synthesis procedure to introduce transport pores into the structures of the synthesized samples. The synthesized samples were characterized with different methods to reveal effects of synthesis method and using hard template on their structure and catalytic performance in methanol to olefin reaction (MTO). DG conversion method results in smaller particle size in comparison with hydrothermal method, resulting in enhancing catalytic performance. On the other side, using CNT in the synthesis procedure with DG method results in more reduction in particle size and formation of hierarchical structure which drastically improves catalytic performance.

Background: Cadmium (Cd) impairs gametogenesis and damages the blood-testis barrier. Objective: As the primary mechanism of Cd-induced damage is oxidative stress, the effects of two natural antioxidants, myo-inositol (MI) and seleno-L-methionine (Se), were evaluated in mice testes. Methods: Eighty-four male C57 BL/6J mice were divided into twelve groups: 0.9% NaCl (vehicle; 1 ml/kg/day i.p.); Se (0.2 mg/kg/day per os); Se (0.4 mg/kg/day per os); MI (360 mg/kg/day per os); MI plus Se (0.2 mg/kg/day); MI plus Se (0.4 mg/kg/day); CdCl2 (2 mg/kg/day i.p.) plus vehicle; CdCl2 plus MI; CdCl2 plus Se (0.2 mg/kg/day); CdCl2 plus Se (0.4 mg/kg/day); CdCl2 plus MI plus Se (0.2 mg/kg/day); and CdCl2 plus MI plus Se (0.4 mg/kg/day). After 14 days, testes were processed for biochemical, structural and immunohistochemical analyses. Results: CdCl2 increased iNOS and TNF-α expression and Malondialdehyde (MDA) levels, lowered glutathione (GSH) and testosterone, induced testicular lesions, and almost eliminated claudin-11 immunoreactivity. Se administration at 0.2 or 0.4 mg/kg significantly reduced iNOS and TNF-α expression, maintained GSH, MDA and testosterone levels, structural changes and low claudin-11 immunoreactivity. MI alone or associated with Se at 0.2 or 0.4 mg/kg significantly reduced iNOS and TNF-α expression and MDA levels, increased GSH and testosterone levels, ameliorated structural organization and increased claudin-11 patches number. Conclusion: We demonstrated a protective effect of MI, a minor role of Se and an evident positive role of the association between MI and Se on Cd-induced damages of the testis. MI alone or associated with Se might protect testes in subjects exposed to toxicants, at least to those with behavior similar to Cd.
