In this article we study the concept of invariance of ratio through an investigation of children's understanding of constancy of taste—that is, the notion that random samples of a given mixture taste the same—using a device that does not resort to conventional symbolism. The paper begins with a definition of constancy of taste and other quantitative analogues. Then it presents a theoretical analysis of how constancy of taste may emerge from the child's additive world and grow into a conception where taste becomes an intensive quantity. The analysis suggests that one's conception of taste constancy is linked in a fundamental way to one's conception of invariance of ratio. Following this analysis, the paper reports a study that demonstrates the absence of taste constancy among sixth-grade children. More specifically, the study shows that sixth-grade children base their judgment of the relative strength of the taste of two samples from the same mixture on at least one of three (extraneous) variables: the relative volumes of the samples to be tasted, whether the mixture is thought of as consisting of a single ingredient or more than one ingredient, and the relative amount of the ingredients stated in the problem.

SummaryThrombelastography, although proven as a useful research tool has not been evaluated for its clinical utility against common coagulation laboratory tests. In this study we compare the thrombelastographic measurements with six common tests (the hematocrit, platelet count, fibrinogen, prothrombin time, activated thromboplastin time and fibrin split products). For such comparisons, two samples of subjects were selected, 141 normal volunteers and 121 patients with cancer. The data was subjected to various statistical techniques such as correlation, ANOVA, canonical and discriminant analysis to measure the extent of the correlations between the two sets of variables and their relative strength to detect blood clotting abnormalities. The results indicate that, although there is a strong relationship between the thrombelastographic variables and these common laboratory tests, the thrombelastographic variables contain additional information on the hemostatic process.

В статье освещен вопрос, связанный с эволюцией понятия терроризма по законодательству России. Актуальность темы определяется, прежде всего, тем, что проявление терроризма представляет собой серьезную угрозу международной и внутренней безопасности каждого отдельного государства, всего международного сообщества в целом. В результате проведенного теоретического анализа отечественного законодательства об ответственности за совершение преступлений террористического характера автором выделено пять исторических этапов (периодов) его становления, представлена их характеристика. В заключение делается вывод о существовании на современном этапе проблемы выработки определения сложного и многогранного понятия «терроризм». Законодательная дефиниция «терроризм» должна быть принципиально полной, содержать характеризующие специфические признаки, соответствующие современным способам его проявлений. Полагаем, что современная дефиниция, изложенная в п. 1 ст. 3 Федерального закона «О противодействии терроризму», пока не идеальна и продолжает требовать к себе внимания со стороны исследователей и законодателя с целью корректировки терминологии. The issue related to the evolution of the concept of terrorism under Russian legislation is examined in the article The relevance of the topic is determined, first of all, by the fact that the manifestation of terrorism is a serious threat to the international and internal security of each individual state, the entire international community as a whole. As a result of the theoretical analysis of domestic legislation on responsibility for crimes of a terrorist nature, the author has identified five historical stages (periods) of its formation, and presented their characteristics. In conclusion, a conclusion is made about the existence at the present stage of the problem of developing a definition of the complex and multifaceted concept of «terrorism». The definition of terrorism should be fundamentally complete, include characterizing specific features characteristic of modern ways of its manifestations. We believe that the modern definition set forth in paragraph 1 of Art. 3 of the Federal Law «On Countering Terrorism» is not ideal yet and continues to require attention from researchers and legislators in order to correct the terminology.

The article gives an analysis of problems of formation of skills in children of the senior preschool age to build stories of different types. On the basis of the theoretical analysis of psycho-pedagogical and special literature, based on the main definition of «building a story», a subordinate term is formulated in relation to the topic of the study: «building stories of different types» The psychological and pedagogical conditions of formation of sustainable skills of creation and expedient use of stories of different types in children of the senior preschool age are revealed and substantiated. The components, criteria, indicators and levels of formation of abilities to build a different type of narration in children of the sixth year of life are determined. The stages of formation of persistent skills for building different types of stories by senior preschoolers are singled out. The lack of effective pedagogical technologies in relation to the formation of skills in the children of the senior preschool age to build and expedient use of narration of comprehensive typing significantly reduces the effective preparation of children to school. The proposed pedagogical and motivational technology for the formation of children of the sixth year of a sustainable ability to create stories of various types provides the small person an effective communicative tool, which will definitely promote its self-realization both in school environment and in career, society, own life. The prospects for further research are outlined, such independent types of stories are presented as a story - an instruction and a story - a presentation.

Definition Of

The article provides a theoretical analysis of Part 1 of Article 82 of the Criminal Code of the Russian Federation, which defines the regime in correctional institutions of the Russian penal system. It is noted that this definition does not correspond to the achievements of modern penitentiary scientific thought about the regime. In particular, it is emphasized that the regime cannot provide conditions for serving a sentence, since it includes these conditions. Also, the regime cannot ensure the protection of convicts, supervision over them and separate maintenance of different categories of convicts, since, on the contrary, the latter are the means of ensuring the regime. According to the authors of the article, the legislator incorrectly uses the phrase regime of detention of convicts, meaning regime of serving a sentence, since they are different legal phenomena. It is noted that the most optimal definition of the regime is presented in the theoretical model of the general part of the new Criminal Code of the Russian Federation, prepared by a group of authors, but the authors also subjected this definition to some adjustments.

Key Aspects

Recent advances in artificial intelligence have brought attention to computational thinking (CT) in school education worldwide. However, little is known about the development of the literacy of CT in children, mainly because of the lack of proper psychometric assessments. We developed the first psychometrically validated assessment on the literacy of CT of children in Chinese elementary schools, coined as the Computational Thinking Assessment for Chinese Elementary Students (CTA-CES). Items were constructed to reflect key aspects of CT such as abstraction, algorithm thinking, decomposition, evaluation, and pattern recognition. To examine the test reliability and validity, we recruited two samples of 280 third- to sixth-grade students in total. Cronbach’s alpha provided evidence for the reliability of the test scores, item response theory analyses demonstrated psychometric appropriateness, whereas construct validity was verified by convergent validity, and criterion-related validity was confirmed by correlations between the CTA-CES and measures related to CT, namely reasoning, spatial ability, and verbal ability. In addition, an fMRI study further demonstrated similar neural activation patterns when students conducted the CTA-CES and programming tasks. Taken together, the CTA-CES is the first reliable and valid instrument for measuring the literacy of CT for Chinese children, and may be applicable to children worldwide.
