Opis:: The study describes the preparation of the phylogenetic differentiation of Bacillus cereus strains. The Bacillus cereus group of bacteria is very important for human and animal health. The multilocus sequence typing scheme has been used to present this group of bacteria’s phylogenetic relationship and structure. The MLST system was established using 60 isolates of B. anthracis, B. cereus sensu stricto, B. thuringiensis, and transitional environment strains of Bacillus spp. As a negative control, five strains of B. subtilis and B. megaterium were used. Primers for amplification and sequencing were designed to target highly conserved internal fragment of seven housekeeping genes: glpF, gmk, ilvD, pta, pur, pycA, and tpi. A total of 22 different sequence types (STs) were distinguished. Analysis of the sequence data showed that all of the Bacillus cereus strains are very closely related. The MLST scheme exhibited a high level of resolution that can be used as an excellent tool for studying the phylogenetic relationship, epidemiology, and population structure of the Bacillus cereus group strains. The MLST method additionally allows us to define the phylogenetic relationship between very closely related strains based on a combination of the sequences of all seven alleles fragments and each of them separately. Thus, this genetic investigation tool is very useful in epidemiological investigation of potential military/ bioterrorist use of B. anthracis.

Opis:: Artykuł przedstawia część rezultatów badawczych uzyskanych w ramach projektu dotyczącego treści i znaczenia charakterystyk osób z niepełnosprawnością intelektualną w stopniu lekkim. Biorąc pod uwagę mnogość tekstów tego rodzaju ograniczono się do wyboru kilku najbardziej reprezentatywnych spośród nich. Zamierzeniem autorów było zwrócenie uwagi na potencjał tkwiący w tych opracowaniach i niebezpieczeństwa związane z nieprawidłowym ich odczytywaniem. Zaproszenie do przemyśleń na ten temat rozpoczęto od przedstawienia zasadności podjętych działań badawczych i ich założeń koncepcyjnych. W niniejszym artykule poddano analizie zagadnienia odnoszące się do właściwości rozwoju osób z niepełnosprawnością intelektualną w stopniu lekkim, zróżnicowania wewnątrzgrupowego omawianej populacji, uwzględniania w charakterystykach grupy odniesienia, sposobu wartościowania opisywanych cech oraz ukazywania powiązań pomiędzy poszczególnymi właściwościami funkcjonowania opisywanej zbiorowości. Informacje dotyczące formy analizowanych charakterystyk zostaną przedstawione w kolejnej publikacji.
The article presents some of the research results obtained under the project on the content and importance of the characteristics of people with mild intellectual disability. Taking into account the multitude of texts of this type, the selection of the most representative among them was limited. The authors' intention is to draw attention to the potential of these texts and the dangers of misreading them. The call for reflection began by presenting the legitimacy of the research activities undertaken and their conceptual assumptions. The issues relating to the developmental characteristics of persons with mild intellectual disabilities were examined, intra-group differentiation of the population concerned, taking into account in the characteristics of the reference group, the way in which the characteristics described are valued and the relationship between the different characteristics of the functioning of the described collective is shown. Information on the form of the analyzed characteristics will be presented in the next publication.

Tytuł:: Зміни стереотипів міжетнічного сприйняття українців північно-західного регіону в період з 2002 по 2015 рік

Opis:: The geopolitical changes in Ukraine that took place in 2014-2016 influenced the psychology of interethnic perception of Ukrainians. This concerns the policy of intergovernmental cooperation and the attitude of Ukrainians towards national minorities living on the territory of Ukraine. Ukrainian society chose a pro-European model of organization of social relations, support for democratic values, which in turn influenced the change in the stereotypes of interethnic perception of Ukrainians. Research on interethnic perception issues was completed by 2016, and therefore reflects a false picture of interethnic interaction between Ukrainians and other ethno-ethnic groups. The relevance of the study is related to the need to update the empirical material, which concerns the psychology of interethnic perception. In our study, we compared the results of the study, which were obtained in 2003 by V.Gorbunova. The survey was conducted among youths living in the northwestern region of Ukraine. As the results of our study showed, there is a group polarization at the level of consciousness of Ukrainians that differentiates ethnonational groups that are in the system of interethnic perceptions of Ukrainians into group associations such as "we" and "them". According to the results of the factorization of the estimation matrix of the peculiarity of certain personality traits at the level stereotypes of interethnic perception of Ukrainians, we distinguished two groups of ethno-national communities: the first group consists of Germans, Americans, Poles, Turks; the second group includes Russians, Chinese, Kazakhs. Belarusians, Ukrainians, Moldovans, Romanians are not included in any ethno-national association, because they do not attribute to themselves the features that are characteristic of the two previous groups. The change in the vector of the geopolitical direction of our society has influenced the semantic structure of the stereotypes of interethnic perception of Ukrainians by other ethno-national groups. There was a differentiation between ethnic groups at the level "we" and "they" and there is a tendency for Ukrainians to consolidate with ethnic groups that are part of the European Union. In comparison with the results of the research in 2002, we found that the main attitudes of Ukrainians in the consciousness of the Ukrainian people were and remain stereotypes of interethnic perception, which denote the personality traits related to the sphere of production and intergroup cooperation (hard work, perseverance, business qualities). Compared to the results of the 2002 study, the features that indicate the ability of the ethno-national group to aggression, hostility, insidiousness become dominant. Stereotypes that denote socially-approved features that are not mediated by joint activity lose sentimentality: sincerity, openness, friendliness, etc. The results of the above study illustrate the peculiarities of the stereotypes of ethnic perceptions of Ukrainians, which were obtained on the basis of a sample of juvenile persons (17-20 years old) living in Zhytomyr, Volyn and Vinnytsia regions. To obtain a holistic view of the specificity of interethnic perception by Ukrainians of other ethno-national groups, it is necessary to continue the study taking into account respondents from other regions of the country and other age groups, which outlines the subject and tasks of our further research.
