Justice Holmes and the Question of Race
Authors: Halper Thomas 
Published: January 2021

Abstract
Notwithstanding his youthful dalliance with abolitionism, Holmes’ votes and opinions in Supreme Court cases involving race reveal a stubborn indifference to discrimination on a range of issues. Whether this reflects a cold personal aloofness, a preoccupation with life as struggle, a commitment to judicial restraint or merely an insensitivity pervading the enlightened opinion of the day, his performance will continue to stain his reputation.
The effect of the pre-wetting of expanded clay aggregate on the freeze-thaw resistance of the expanded clay aggregate concrete

Abstract
This paper presents experimental research on expanded clay aggregate concrete. The aim of the investigations was to determine if the pre-wetting of expanded clay aggregate has an effect on the freeze-thaw durability of the expanded clay aggregate concrete. Five concrete series based on the same concrete mix design were made and tested. The degree of pre-wetting of the aggregate was varied: dry aggregate was used in the first series, aggregate with a moisture content of 10% was used in series IA and IB and aggregate with a moisture content of 25% was used in series IIA and IIB. Also the approach to the production process was varied: in series A the water contained in the aggregate was taken into account in the global water-cement ratio (consequently a reduced amount of water was added to the mix), whereas in series B the nominal amount of water was added to the mix (as in the case of dry aggregate). The freeze-thaw resistance criterion was based on the assessment of the decrease of compressive strength and increase in weight loss after exposure to freeze-thaw cycles. The expanded clay aggregate concrete's strength and mass decrements caused by freeze-thaw cycling were used as the measure of its freeze-thaw resistance. The investigations have shown that the pre-wetting of expanded clay aggregate has an effect on the freeze-thaw durability of the expanded clay aggregate concrete. The differences of concrete compressive strength decrease related to freeze-thaw durability may be 2 to 5 times greater when inadequate method of calculating mixing water for concrete is used.

INTEGRATION OF FARMERS AND PROCESSING INDUSTRY IN THE AQUACULTURE VALUE CHAIN IN TOCANTINS, BRAZIL
Authors: Xavier Pedroza Filho Manoel , Castilho Maurício Araujo 
Published: January 2021

Most of the fish farmed by small scale Brazilian fish farmers in Brazil is sold directly to local markets without passing through a processing industry. The integration between small-scale fish farmers and the processing industry is restricted to few cooperatives, mainly in the southern region. Although many fish processing plants are operating in different regions, most producers do not have access to them. The lack of integration creates several problems, including low quality of fish due to the absence of sanitary control, informality, impossibility to access supermarkets, and low added value. This paper is based on a case study of aquaculture in the Brazilian state of Tocantins, by using the Global Value Chain approach. The methodology consists of a qualitative process based on face-to-face interviews with value chain agents. The main results indicate that the processing industries are increasing their own production and implementing supply contracts with large producers. More vertical governance is emerging with a high level of control by the industries. Thus, many small-scale fish farmers are being excluded from the value chain.

Authors: Shekharappa Kanavi Roopa , Tejaswi C. N. , Patil Savita S. , Lakshmikanth B. M. 
Published: January 2021

Objectives:
A deluge of techniques are made available for students to encourage for self-directed learning. Microteaching is one of the old techniques which is traditionally used as a method to improve pedagogical skills. Incorporating microteaching techniques in student seminars enhance the effectiveness of the learning process. The objectives of the study were to assess the effectiveness and perceptions regarding microteaching methodology in improving the undergraduate student seminars.

Materials and Methods:
The study was conducted among ten randomly selected 1st year MBBS students. They were assigned a seminar topic from pre-discussed lecture in Physiology. They were divided into two equal groups and one group underwent training in microteaching through a workshop. Each student from both the groups presented seminar which was evaluated on Likert’s scale by standardised blinded observers consisting of 13 faculty and 12 students. Perceptions of students were assessed by self-evaluation. The data were analysed by Chi-square and Mann–Whitney U-test.

Results:
Each student was evaluated by 25 members and got 125 responses from each group. The median score for all the components in the assessment was significantly higher in the intervention group as compared to the control group. The presentation skills, providing non-verbal clues and stating the objectives were significantly better among the microteaching trained group (P ≤ 0.05). Common perception among the intervention group was that they found it interesting, innovative, improved presentation skills, interactive and needed preparation for application and analysis, whereas some students felt lack of time and motivation were the obstacles for implementation of microteaching methodology for student seminars.

Conclusion:
The students found microteaching methodology to be very interesting and useful learning tool. Microteaching technique assists students to develop competence and confidence in seminar presentations.
EVOLUTIONAL AND CREATION PARADIGMS OF THE ORIGIN OF THE WORLD: HISTORY AND MODERNITY
Authors: Алёхина Евгения Викторовна 
Published: January 2021

В статье рассмотрены возникновение и развитие противоборствующих в философской мысли креационного и эволюционного объяснений происхождения Вселенной, жизни и разума. Обращаясь к анализу двух парадигм, автор показала, что они имеют длительную историю противостояния. В наше время, как и в прошлом, эта проблема сводится к альтернативе - либо эволюция как продукт слепой случайности, либо целенаправленное творчество Высшего Разума. В последнем случае есть два варианта: ортодоксальный и модернистский - «телеологический эволюционизм». Обосновывается, что современная постнеклассическая наука все больше определяется социальными, культурными и мировоззренческими основаниями. Одной из точек пересечения трех уровней научного знания является проблема происхождения мира. Противоположные варианты её решения имеют различное соотношение собственно научного (экспериментального) и мировоззренческого аспектов. Эволюционная гипотеза с позиции диалектического материализма не смогла преодолеть редукционизм и наивный реализм механистического подхода. Наличие в указанных парадигмах аксиологического компонента в той или иной степени утверждает или отрицает смысл жизни и достоинство личности.
The article examines the emergence and development of the opposing creation and evolutionary explanations of the origin of the universe, life and mind in philosophical thought. Turning to the analysis of the two paradigms, the author showed that they have a long history of opposition. In our time, as in the past, this problem boils down to an alternative - either evolution as a product of blind chance, or purposeful creativity of the Higher Reason. In the latter case, there are two options: orthodox and modernist - «teleological evolutionism». It is substantiated that modern post-non-classical science is increasingly determined by social, cultural and ideological foundations. One of the intersection points of the three levels of scientific knowledge is the problem of the Origin of the World. Opposite solutions to its solution have a different ratio of the scientific (experimental) and worldview aspects. The evolutionary hypothesis could not overcome the reductionism and naive realism of the mechanistic approach from the standpoint of dialectical materialism. The presence of an axiological component in these paradigms, to one degree or another, affirms or denies the meaning of life and the dignity of the individual.

FATHERS AND SONS: DISCURSIVE STRATEGIES OF NETWORK COMMUNITIES IN CONTEMPORARY RUSSIA
Authors: Козлова Наталия Николаевна , Рассадин Сергей Валентинович 
Published: January 2021

Актуальность исследования определяется противоречивостью современного прочтения ряда когерентных феноменов - семьи, родительства, материнства, отцовства, детства. Объектом исследования являются дискурсы российских сетевых сообществ отцов, которые выстраиваются вокруг проблем современной семейной и демографической политики. Новизна исследования состоит в дискурсивном анализе нарратива отцовских сообществ, рассмотрении представлений участников сообществ об отцовстве как социальном феномене. Анализируя интерактивный сайт Фонда поддержки семьи и семейных ценностей «Отцовство» и его сетевые ресурсы авторы приходят к выводу, что дискурсивно отцовство рассматривается в двух планах - как условие для развития ребенка и как часть личностной сферы мужчины. По результатам исследования выявляется новая дискурсивная стратегия отцовства - модель «отца-менеджера», в рамках которой актуализируются компетенции социально активного ответственного отцовства.
The relevance of the study is determined by the inconsistency of the modern interpretation of a number of coherent phenomena - family, parenting, motherhood, paternity, childhood. The object of the research is the discourses of the Russian network communities of fathers, which are built around the problems of modern family and demographic policy. The novelty of the research lies in the discursive analysis of the narrative of paternal communities, consideration of the ideas of community members about paternity as a social phenomenon. Analyzing the interactive website of the Fund for Support of Family and Family Values «Fatherhood» and its network resources, the authors come to the conclusion that discursively, paternity is viewed in two ways - as a condition for the development of a child and as a part of a man's personal sphere. According to the results of the study, a new discursive strategy of fatherhood is revealed - the «father-manager» model, within the framework of which the competences of socially active responsible fatherhood are actualized.
