Conformity and Reaction to Error: An ERPs Study

This article is devoted to the analysis of cognitive indicators of conformal behavior. It presents the results of the study of EEG-correlates of conformity. The hypothesis of the study is that people who tend to the conformal behavior have a similar way of response on the errors and disagreement with the majority opinion. Theexperiment involved 20 participants: 11 – nonconformists, 9 – conformists according to tests (‘Interpersonal Behavior Circle’ by T. Leary and ‘Portrait Values Questionnaire’ by S. Schwartz). Participants took part in two types of tasks: arithmetic tasks and attractiveness evaluation. After solving the tasks, participants were given feedback about right/wrong decisions in arithmetic tasks, and agreement/disagreement with the majority opinion in the evaluation of people’s attractiveness. This study analyzed event-related potentials (ERPs) in the case of error or disagreement with the majority opinion. The results of the study showed the differences in the indicators of bioelectric brain activity between conformal and nonconformal participants after the disagreement with the majority opinion. Conformal participants demonstrate higher amplitude of P300 wave upon presentation of the feedback of the disagreement with the majority opinion. Thus, the conformal behavior in a situation of disagreement with others’ opinion accompanied by specific ERP patterns of the brain associated with the correction of behavior. Keywords: conformity, error processing, event-related potentials, P300, error-related negativit

U-Pb LA-ICP-MS DATING OF DETRITAL ZIRCON FROM UPPER PERMIAN SANDSTONE OF THE BOYEVAYA GORA SECTION (ORENBURG REGION, SOUTHERN CIS-URALS)

The first results of U-Pb LA-ICP-MS dating of 150 detrital zircon grains from the Upper Permian sandstone of the Boyevaya Gora section (Orenburg region, the Southern Cis-Urals) are presented. 95 conditional zircon U-Pb isotopic dates form two age peaks – 381 and 529 Ma. It is assumed that clastic material entered the sedimentation basin mainly due to erosion of the Early Hercynian Ural complexes and relics of the Protouralian-Timanian orogen

Algorithm of Hepatitis B Vaccinal Prevention at Children with Acute Lymphoblastic Leukemia in Dynamics of Program Therapy

Purpose: To create the algorithm of hepatitis B vaccinal prevention at children with acute lymphoblastic leukemia. Materials and Methods: The data of 181 children with acute lymphoblastic leukemia, from which 99 patients received specific hepatitis B prevention with vaccine «Engerix B», have been investigated. The authors have assessed correlations between efficiency of offered vaccinal prevention and leuco/neutropenia degrees at patients in days of vaccinations. The analysis of hepatitis B infect level at stages of vaccination was carried out. Results: The algorithm of hepatitis B vaccinal prevention at children with acute lymphoblastic leukemia is offered

ПЕРВЫЕ РЕЗУЛЬТАТЫ U-Pb LA-ICP-MS ДАТИРОВАНИЯ ОБЛОМОЧНОГО ЦИРКОНА ИЗ ВЕРХНЕПЕРМСКИХ ПЕСЧАНИКОВ РАЗРЕЗА БОЕВАЯ ГОРА (ОРЕНБУРГСКАЯ ОБЛАСТЬ, ЮЖНОЕ ПРЕДУРАЛЬЕ)

The first results of U-Pb LA-ICP-MS dating of 150 detrital zircon grains from the Upper Permian sandstone of the Boyevaya Gora section (Orenburg region, the Southern Cis-Urals) are presented. 95 conditional zircon U-Pb isotopic dates form two age peaks – 381 and 529 Ma. It is assumed that clastic material entered the sedimentation basin mainly due to erosion of the Early Hercynian Ural complexes and relics of the Protouralian-Timanian orogen. Представлены первые результаты U-Pb LA-ICP-MS датирования 150 зерен обломочного циркона из песчаников терминальной перми разреза Боевая Гора (Оренбургская область, Южное Предуралье). В полученном по 95 кондиционным оценкам изотопного возраста распределении отчетливо доминирует палеозойская популяция с двумя максимумами – 381 и 529 млн лет. Предполагается, что обломочный материал поступал в бассейн осадконакопления главным образом за счет эрозии как раннегерцинских комплексов Уральского орогена, так и реликтов Протоуральско-Тиманского складчатого сооружения.
