Response inhibition in the Negative Compatibility Effect in the absence of inhibitory stimulus features
Authors: Schmidt Thomas , Panis Sven , Wolkersdorfer Maximilian P. , Vorberg Dirk
Published: August 2022

The Negative Compatibility Effect (NCE) is a reversal in priming effects that can occur when a masked arrow prime is followed by an arrow target at a long stimulus-onset asynchrony (SOA). To test the explanation that the NCE is actually a positive priming effect elicited by mask features associated with the prime-opposed response, we devise masks that always point in the same direction as the prime, eliminating all antiprime features. We find large positive priming effects for arrow primes without masks and for arrow masks without primes. When a neutral mask is introduced, priming effects turn negative at long SOAs. In the critical case where the mask is an arrow in the same direction as the prime, the prime does not add to the positive priming effect from the mask shape, but instead strongly diminishes it and induces response errors even though all stimuli point in the same direction. No such feature-free inhibition is seen when arrows are replaced by color stimuli. We conclude that even though response activation by stimulus features plays a role in the NCE, there is a strong inhibitory component (though perhaps not in all feature domains) that is not based on visual features.

Bipolar disorder (BD) is a chronic mood disorder characterized by manic and depressive episodes. Dysregulation of neuroplasticity and calcium homeostasis are frequently observed in BD patients, but the underlying molecular mechanisms are largely unknown. Here, we show that miR‐499‐5p regulates dendritogenesis and cognitive function by downregulating the BD risk gene CACNB2. miR‐499‐5p expression is increased in peripheral blood of BD patients, as well as in the hippocampus of rats which underwent juvenile social isolation. In rat hippocampal neurons, miR‐499‐5p impairs dendritogenesis and reduces surface expression and activity of the L‐type calcium channel Cav1.2. We further identified CACNB2, which encodes a regulatory β‐subunit of Cav1.2, as a direct functional target of miR‐499‐5p in neurons. miR‐499‐5p overexpression in the hippocampus in vivo induces short‐term memory impairments selectively in rats haploinsufficient for the Cav1.2 pore forming subunit Cacna1c. In humans, miR‐499‐5p expression is negatively associated with gray matter volumes of the left superior temporal gyrus, a region implicated in auditory and emotional processing. We propose that stress‐induced miR‐499‐5p overexpression contributes to dendritic impairments, deregulated calcium homeostasis, and neurocognitive dysfunction in BD.
Secular as political theology in russian religious philosophy of the first half of the 20th century
Authors: Solovev Artem
Published: August 2022

The article is devoted to the problem of understanding the secular as political theology in Russian religious philosophy of the first half of the 20th century. The connection between the concept of «political theology» and the concept of «secular» is carried out in accordance with the approach of K. Schmitt. Schmitt’s approach is proposed to be expanded to understand political theology as borrowing the structure of theistic theology by other means for secular purposes. In the article, this approach is used to identify what can be defined as the analysis of «political theologies» in the works of Russian religious philosophers of the first half of the 20th century. The study determines that the secular as political theology appears as the «religion of anthropolatry» of the Russian intelligentsia for Merezhkovsky and Bulgakov, and appears as the mythology of communism for Losev and Florensky. The article concludes that the political theologies of socialism and communism are the result of the secularization of the Jewish apocalyptic and Christian chiliasm for Bulgakov, Berdyaev, Losev. Whereas, socialism and communism are secular variants of Gnosticism, which he defines as «the heresy of utopianism» from Frank’s point of view. The article concludes that understanding of the secular as political theology allows us to interpret the phenomenon of religious conversion, which is considered as the beginning of Russian religious philosophy, as a transition from political theology to theistic theology, and not just as a transition from atheism and skepticism to faith. It also states the possibility of applying the concept of confessionalization to understand cultural criticism of modern political theologies by Russian religious philosophers of the first half of the 20th century.
Psychological Foundations of Legal Nihilism

Published: August 2022

Introduction: the paper discusses the psychological foundations of legal nihilism through the prism of law as a socio-cultural and psychological integrity. The purpose of the study is to analyze legal nihilism from the point of view of legal psychology and to determine the ways to overcome the psychological deformation of legal consciousness. Objectives of the work: to identify the factors that generate psychological deformation of legal consciousness, to determine the role of legal mentality and psychological dominant in the formation of legal nihilism, to characterize the role of intuitive law in the perception and implementation of positive law, to identify the main directions of the educational process to overcome this negative phenomenon. Methods: dialectical-materialistic, synergetic, interdisciplinary, analysis, synthesis, induction, deduction, interpretation of law, legal modeling. Results: legal nihilism has deep conscious-unconscious psychological foundations of deformed legal consciousness associated with the implementation of dominant attitudes, emotional experiences and forms of psychological protection. Due in law becomes an actual legal regulator only if the individual’s psyche passes and accepts his internalization. Otherwise, the law, as a rational-imperative rule, will cause psychological opposition to implementation. Conclusions: ignoring the psychological component of the state policy in the field of legal education and legal realization against the background of the aggravation of military danger, external isolation, sanctions policy, pandemic, falling living standards of the population will lead to an increase in legal nihilism. The way out is the legalization and legitimization of power, the improvement of the democratic and social orientation of the state through the investment support of the state, the innovative restructuring of the economic mechanism, the consolidation of society around the state power, increasing the level of psychological culture of educational and disciplinary processes.
Formations, Chiefdom and Early State: Why “Vulgar Marxism” Does Not Explain Process of State Formation in the World Perspective
Authors:   Vladivostok State University of Economics and Service, Pertsev Dmitry
Published: August 2022

Introduction: at the present stage of the development of Russian humanities, one-linear theories, among them “vulgar Marxism”, do not fully analyze the course of politogenesis in the world perspective. Thanks to the accumulated data of non-evolutionary anthropology, it has been revealed that the process of the emergence of the state did not always, or rather, even rarely, occur “in a straight line”, in other words, it developed from simple to complex. Purpose: to show that according to the studies of recent decades, social evolution does not have a strictly defined direction, it is often variable. Methods: the methodological basis of the article is the general scientific dialectical method, as well as the method of analysis and synthesis. Results: the article revealed that among the examples of inconsistencies between “vulgar Marxism” regarding politogenesis and historical reality, there are a number of structures that do not fit into the framework of Marxism. In other words, we turn to the experience of Europe during the period of barbarian kingdoms (V-IX centuries), the Greek policy and the nomadic empires of Eurasia (XII-XIII centuries). These examples, and many others, break the unilinear scheme, demonstrating alternative paths to civilization.

Published: August 2022

Introduction: the paper discusses the analysis of measures and directions of the state support for the investment industry in the context of the global COVID-19 virus pandemic, which are being implemented in the Russian Federation and the Republic of Kazakhstan. Purpose: to study measures of the state support for the investment industry in the Russian Federation and the Republic of Kazakhstan in the context of the COVID-19 pandemic. Methods: the empirical methods of comparison, description, interpretation; the theoretical methods of formal and dialectical logic. Results: the conducted research shows that the experience of the state support of the investment industry in the Russian Federation and the Republic of Kazakhstan has many common trends, uses similar tools and methods, but additional state support is required to get the industry out of the crisis. Conclusions: the state support of the investment industry in the face of new challenges caused by the global economic crisis provoked by the COVID-19 is the most important task of any state if it seeks to develop its own economy and not be in the rearguard of economic development.

Published: August 2022

Introduction: the prosecutor in criminal proceedings is one of the main participants of the prosecution, who has state powers related to the supervision over the procedural activities of the preliminary investigation bodies. The active position of the prosecutor determines the state of legality in the law enforcement activities of the investigation and inquiry bodies necessary to respect the rights and legitimate interests of parties to a criminal proceeding. For the exercise of procedural powers by the prosecutor, the scope of tasks stipulated by human rights activities and ensuring the safety of parties to a proceeding is provided. However, the scope of these powers has been significantly reduced, and therefore is insufficient for the effective supervision in the pre-trial stages of the criminal process. In this regard, the purpose of the study is to identify the main activities of the prosecutor in the implementation of criminal prosecution and supervision over the procedural activities of the investigator and the interrogating officer, based on the principles of legality, unity and centralization. The objectives of the study include: the assessment of the prosecutor’s activities and his functions in pre-trial proceedings; the development on this basis of proposals to improve the legal status of the prosecutor. Methods: the methodological framework for the study is the general scientific systematic method of cognition, through which the approaches are formulated, caused by the increasing importance of the procedural activities of the prosecutor’s office at the stages of initiation of a criminal case and preliminary investigation as the main law enforcement agency that supervise the implementation of the rule of law regime as the systemic integrity of certain norms of law governing legal relations in pre-trial proceedings. Results: the authors’ position on the content of the prosecutor’s supervision over the procedural activities of the preliminary investigation bodies is reasoned, which corresponds to the human rights role and the constitutional guarantees of the recognition of human and civil rights and freedoms as the highest human value whose protection is a direct responsibility of the state. Conclusions: the implementation of the results obtained by the paper’s authors will optimize the idea of the need to improve the legal status of the prosecutor, caused by the requirement of establishing the uniform supervisory powers of the prosecutor to investigate and inquire, giving him the right to initiate criminal proceedings, as well as to balance the procedural powers of the prosecutor and the head of the investigative body, for more effective implementation of the prosecutor’s supervisory function.

The article is devoted to the study of a unique phenomenon of Chinese socio-economic reality – the phenomenon of "left behind children". It proposes a specific approach to the study of such children, which consists in considering them in adulthood as subjects of parental labor already implemented by them. The purpose of our study is to develop the theoretical and methodological foundations of the sociological study of "left behind children" as subjects of parental labor in China. The study is planned to identify the specifics of the organization of work of Chinese subjects of parental labor, who are "left behind children", to conduct a comparative analysis of the motivation of parental work in various subjects of this type of labor in China, to assess the satisfaction with parental work of its subjects, who themselves were "left behind children". The following methodological principles of their study are proposed: application of an interdisciplinary approach; the use of a differentiated study of the characteristics of various subjects of parental labor, who are "left behind children"; consideration of regional differences; a combination of various methods of collecting information and a set of statistical methods for analysis; labor approach to the study of this phenomenon and based on the results obtained in the study of parental labor. The article presents a set of empirical indicators for the sociological study of the phenomenon of parental labor, the subjects of which are the Chinese "left behind children". We divide the system of empirical indicators into three levels: 1) research objectives are the three contents of the research plan; 2) blocks of empirical indicators include: conditions for the implementation of parental labor, the time it takes to implement parental labor; internal needs, external incentives; the expectations of the subjects of parental labor, the perceived quality of parental labor, satisfaction with the relationship between parents and children, confrontation between parents and children; 3) multiple empirical indicators under the block of empirical indicators.

The study of the phenomenon of agglomeration analyzes settlement system, agglomeration effects, industry location. Foreign experience of public policy shows the evolution of the urban structure towards growth of additional employment centers as an effective tool for population decentralization and improvement of living standards and environmental quality. In Russia, large cities have high population growth rates, and the standard of living of the suburbs is still lower than in the agglomeration “cores”. Social and economic situation of Krasnodar, Novorossiysk and Sochi agglomerations is characterized by the following indicators: population, average wage, investment, shipped production, area of dwelling unit per capita. Half of the population of the region lives within the agglomerations, which account for 60% of shipped production, 70% of own investments. Wages and housing provision in large cities are significantly higher than in average in the region. High dynamics of population growth is due to migration (intraregional and from other regions of Russia) to the central areas of the agglomeration, which have higher level of social and economic development and accessibility to infrastructure. At the same time, centripetal processes worsen problems of urban environment. Development of agglomeration planning connected with Development strategy of Krasnodar Krai and industrial programs taking into account the economic relationships between “core” and periphery will form the legal basis for the design and management of the agglomeration as a single territorial object.

The need for digital transformation of agro-industrial complex of the Russian Federation and the land improvement industry is directly connected with the processes that ensure the creation of digital products and the use of digitized technologies in the industry. Thus, according to the analytical center of the Ministry of Agriculture of the Russian Federation, the influence of information technologies on the cost of grain production was revealed. It showed that investments in IT products for the industry connected with the operation of irrigation systems give a reduction in costs by approximately 16%. Such a result will undoubtedly contribute to an increase in labor productivity in the industry, and, consequently, increase the competitiveness and financial stability of the firms. As the subject of the study, the authors identified the conditions of digital transformation in the land improvement industry of the agro-industrial complex of the Russian Federation. The aim of the paper was to identify favorable opportunities and counteracting factors in the development of the digitalization process of land improvement industry, as well as to identify the strong and weak characteristics of the firms as participants in this process. In the article, such research methods as statistical, situational, logical and SWOT analyses were used. As the results of the study, the authors made the conclusion that allows us to emphasize the features of the digital space of land improvement industry. The conclusions made it possible to obtain an objective assessment of current conditions of digitalization of land improvement, plan and predict both positive and negative trends of digital transformation for firms in land improvement, and mobilize more reasonably a variety of resources necessary for adaptation and digital breakthrough in the land improvement industry.

Due to the increasing influence of new media, the usual communication environment of interaction between traditional media and the audience is undergoing a period of transformation. The authors identified the factors and conditions for the development of work with the target audience of new media, primarily social networks and the blogs, when the information consumer becomes the axis of interaction in the communication process; the criteria of new media are indicated, their conceptual apparatus is defined. The analysis made it possible to conclude that the functions of the mass media are undergoing changes at the macro and micro levels within a particular group, organization, and community. The structural, functional and communicative approaches of research allowed the authors of the article to develop a structural model of the functions of modern communication environment at the regional level, what ensures the information needs of the population, realization of the needs for socialization, civic solidarity and mobilization of the population at the mesolevel. Such a scenario gives the regional media the opportunity to update the toolkit, transforming it to the new professional tasks of media science and new multimedia narratives. The authors believe that all platforms in modern society are focused around the audience, and not only the platforms benefit from this interaction, but also users who save time by performing certain actions including the activities in a specific region. The obtained results allow us to confirm that the problem of intercultural interaction and promotion of a positive image of regions in the virtual space present significant scientific and practical interest in the use of information and communication technologies at the mesolevel of economy.

Published: August 2022

The complex analysis of different territorial units, regions or micro-regions is a very topical issue today, both globally and in Hungary. As we know, it is the continuity of changes at the spatial level that causes spatial inequalities, so it can be said that no two spatial units on Earth have the same characteristics. These changes have an impact on the economic growth, competitiveness and spatial development of a given territory, as well as on the living conditions and living standards of its inhabitants. As a result of the continuous changes in social, economic and infrastructural factors, we will examine a very complex issue, the main focus of which will be on the developmental differences and trends in the Hungarian districts (LAU1). In Hungary, the district system, which is the territorial level between settlements and counties, has a long history, since the earliest districts were established in the 13th century as administrative formations. Nowadays, districts (LAU1) are also located between the administrative level of counties and municipalities, as the lowest territorial and organisational level of state administration. The establishment of districts and the amendment of the related legislation is provided for in Act XCIII of 2012. In total, there are 197 districts, 23 of which are in the capital city.

EFFECTS OF HIGH-INTENSITY GYMNASTICS ON SKELETAL MUSCLE PROTEINS
Authors: Xu Chengbo
Published: August 2022

ABSTRACT Introduction: Although the current method of muscle stretching in gymnastics teaching in colleges and universities can reduce sports fatigue, it has been shown to have little effect on the well-being of athletes because it requires a long recovery time from psychological fatigue. Progressive muscle relaxation training is a method that uses the basic principle of sympathetic nerve activity to reduce the impact of negative emotions psychologically and relieve fatigue physiologically, requiring a further study of its impact on muscle protein. Objective: Explore the effect of high-intensity gymnastics on skeletal muscle protein and study the progressive muscle relaxation training method post-workout adjustment. Methods: After three weeks of training, excluding the standard deviations in the experimental data caused by the athletes’ irregular movements, the athletes’ blood lactate content and heart rate were counted and recorded. The collected data were analyzed using Excel software to integrate and compare the data using the T-test method. Results: After exercise training, the skeletal muscle function indices of the subjects increased to different degrees. From the point of view of heart rate recovery efficiency, the rate of heart rate decline of progressive relaxation training was higher than that of the two groups, and the degree of fluctuation was lower than that of the two groups, indicating that the level of recovery in heart rate of progressive relaxation training was better. Conclusion: The action of the high-intensity gymnastics team has a good effect on improving the athletes’ skeletal muscle and skeletal muscle proteins. Post-exercise conditioning training plays an important role in athletes’ physical recovery. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Published: August 2022

ABSTRACT Performance indicators are tools capable of exposing measurable characteristics and generating relevant information on forest operations, thus being considered pillars for managers to make agile and assertive decisions. Forest extraction with a forwarder must be improved, understanding the factors that affect the costs of this machine, such as productivity (PR), fuel consumption (FC), operational efficiency (OE), and quality of operation. Thus, the objective of this study was to evaluate the implementation of the Overall Efficiency of Forest Machines (OEFM) indicator in the management of forest extraction data using forwarders. Data were collected during forest harvesting from five operating fleets, in commercial eucalypt plantations, in full-tree and coppice regimes, in the states of Bahia and Espírito Santo. The indicator was expressed as a percentage calculated by OEFM = ( ( 4 ∗ PR ) + ( 3 ∗ FC ) + ( 3 ∗ OE ) ) / 10. The performance of the machines was evaluated by a stochastic model of dynamic simulation of systems in eight scenarios, proposing improvement for the average individual volume harvested, fuel consumption, and mechanical or operational stops. Analyzes were performed using PowerSim Studio 9 software. The OEFM of two fleets was higher than the established target of 95.17%, with 95.72% and 97.44%. The OEFM indicator proved to be useful in the management of forest extraction with adequate and easy-to-understand information from a large amount and variety of data. The stochastic simulation model was efficient to study the impact on the global efficiency and the flow of wood extraction by the forwarder.

Resumo Características reprodutivas refletem diretamente no desempenho produtivo visto que são capazes de determinar o número de bezerros nascidos anualmente, além de afetar o intervalo entre gerações e, consequentemente, a intensidade de seleção, fazendo com o que tais atributos sejam apontados como variáveis econômicas das mais importantes que afetam diretamente o sistema de produção. O presente estudo propõe realizar uma revisão de literatura de polimorfismos de genes do eixo somatotrópico associados a funções reprodutivas em novilhas e vacas (Bos taurus taurus e Bos taurus indicus), indicadas pelos índices: número de serviços por gestação (Nº serviços/gestação), idade ao primeiro parto (IPP), intervalo de partos (IP) e período de serviço, como também denominado de intervalo parto-concepção (IPC). As pesquisas encontradas durante o período de 2011 a 2021 demonstraram associações entre todos os indicadores de eficiência reprodutiva analisados de novilhas e vacas com 27 polimorfismos de nucleotídeo único (SNPs), sendo 18 em GHR, 5 em IGF-I e 4 em STAT5A. Dessa forma, este estudo mostrou relação entre os SNPs e os indicadores de eficiência reprodutiva, demonstrando que técnicas de genética molecular potencializam o processo de seleção dos animais, resultando em sistemas mais lucrativos e que se sustentam a longo prazo.
Vaccine refusal/ hesitancy- the ethical standpoint regarding the COVID-19 pandemic
Authors: Gentil João Daniel da Cruz
Published: August 2022

ABSTRACT Objective: To reflect about vaccine hesitancy from ethical and bioethical perspectives. Methodology: Reflective study through the analysis of bibliographic research carried out from December 2020 to May 2021 in the data banks SciELO, PubMed, Direção Geral da Saúde, and Ordem dos Enfermeiros. Results: Vaccination aims at collective protection. The effects desirable in the individual do not have the same ethical value in the collective, leading to cost-benefit imbalances. The insufficiency of principlist Bioethics leads us to use other moral values, such as responsibility, solidarity, and social justice, to reflect on problems related to vaccination. Conclusion: In ethics there are no perfect solutions, and they depend on the context. Group immunity is one of the most discussed issues in a pandemic. Equitable distribution and the principle of justice are reflected daily in the nursing profession.

RESUMO Objetivo: Analisar o padrão espaço-temporal e os fatores relacionados à mortalidade infantil no Nordeste brasileiro de 2008 a 2018. Método: Estudo ecológico desenvolvido com óbitos infantis ocorridos no Nordeste e notificados no Sistema de Informação sobre Mortalidade. Utilizou-se os modelos de regressão não espacial e espacial para identificar indicadores relacionados à mortalidade infantil. Resultados: A taxa de mortalidade apresentou tendência decrescente de 2,1% ao ano (IC95%:-2,7 - -1,6; p<0,001), com maiores coeficientes bayesianos concentrados em municípios do interior do Piauí. As variáveis relacionadas a mortalidade infantil foram: Índice de Gini (β=6,56; p=0,01), Índice de Desenvolvimento Humano Municipal (β=-22,21; p<0,001), razão de dependência (β=0,16; p<0,001), percentual de pessoas em domicílios sem energia elétrica (β=-0.12; p<0,001) e percentual de mulheres de dez a dezessete anos que tiveram filhos (β=0,19; p=0,01). Conclusão: Observou-se diminuição da mortalidade infantil no período estudado e altas taxas bayesianas no interior piauiense.

ABSTRACT Objective: To analyze the effect of an educational intervention on the attitudes of university professors towards suicidal behavior. Methods: Experimental study, which carried out an educational intervention with 100 university professors, divided into two groups, control and intervention, developed in three moments, pre-assessment, intervention, and post-assessment, using the Eskin’s Attitudes Towards Suicide Scale (E-ATSS). Comparisons before and after intervention in the same group were performed using the paired t-test for dependent samples and the Wilcoxon Signed Rank Test, and for comparisons between groups the paired t-test for independent samples and the Mann-Whitney U test were used, the significance level adopted was p < 0.05. Results: There was a change in the attitude of professors in the two domains of the suicide scale such as mental illness (p<0.001) and punishment after death (p<0.001) whose attitudes were negative in the pre-assessment phase. For the control group, no changes were observed. Conclusion: The educational intervention promoted positive changes in attitudes, with a significant change evaluated at the end of the intervention in the domains: suicide as mental illness and punishment after death.

ABSTRACT Objective: To assess the level of agreement between the Subjective Frailty Assessment (SFA) and Clinical Functional Vulnerability Index (CFVI-20) for the diagnosis of frailty in older adults. Methods: A descriptive, comparative, cross-sectional study was conducted in 2018/2019 with 492 older adults at nine Family Health Strategy units in the city of Três Lagoas, state of Mato Grosso do Sul, Brazil. Frailty was assessed using the SFA and CFVI-20 in addition to a structured interview. The Wilcoxon test and Pearson's chi-squared test were used for the comparisons. Results: Agreement was 35.4%, with a Kappa coefficient of 0.11. After dichotomizing the sample into frail and non-frail individuals, agreement was 70.1%, with a Kappa coefficient of 0.41 and Cronbach's alpha coefficients of 0.61 and 0.74 for IVCF-20 and SFA, respectively. The prevalence of frailty was lower using the IVCF-20 (17.1%) compared to 59.8% using the SFA. Conclusion: Agreement regarding the classification of frailty between the two instruments ranged from low to moderate. This finding underscores the need for a standardized instrument for measuring frailty in community-dwelling older adults.

ABSTRACT The development of more drought-tolerant cultivars is essential for the maintenance of global agricultural production. This study aimed to perform an early selection of drought-tolerant Coffea arabica genotypes by evaluating their functional divergence using morphological, anatomical and physiological analyses. Seedlings of 14 genotypes were subjected to the drought stress imposed by irrigation for 18 days. Growth and anatomical parameters, leaf water potential and gas exchanges were measured. Under irrigated conditions and prolonged drought (18 days), the divergence among the genotypes was determined mainly by morphological traits, such as leaf area, stem diameter and, consequently, shoot dry mass. Under moderate drought (14 days), parameters such as water potential, cuticle thickness, stomatal density, number of xylem vessels and water-use efficiency were important for the divergence of the group with the highest ability to maintain its water status. The genotypes 1, 2, 4, 11 and 12 have characteristics that contributed to the maintenance of water status, such as greater cuticle thickness, stomatal density, smaller number of xylem vessels and phloem thickness, bigger root length and greater water-use efficiency. The functional divergence combining morphological, anatomical and physiological analyses in response to the moderate drought indicated the early selection of the genotypes 1, 2,4, 11 and 12 as more drought tolerant during the seedling stage.
