A Single Mechanism for Global and Selective Response Inhibition under the Influence of Motor Preparation
Authors: Raud Liisa , Huster René J. , Ivry Richard B. , Labruna Ludovica , Messel Mari S. , Greenhouse Ian
Published: September 2020

In our everyday behavior, we frequently cancel one movement while continuing others. Two competing models have been suggested for the cancellation of such specific actions: (1) the abrupt engagement of a unitary global inhibitory mechanism followed by reinitiation of the continuing actions; or (2) a balance between distinct global and selective inhibitory mechanisms. To evaluate these models, we examined behavioral and physiological markers of proactive control, motor preparation, and response inhibition using a combination of behavioral task performance measures, electromyography, electroencephalography, and motor evoked potentials elicited with transcranial magnetic stimulation. Healthy human participants of either sex performed two versions of a stop signal task with cues incorporating proactive control: a unimanual task involving the initiation and inhibition of a single response, and a bimanual task involving the selective stopping of one of two prepared responses. Stopping latencies, motor evoked potentials, and frontal β power (13–20 Hz) did not differ between the unimanual and bimanual tasks. However, evidence for selective proactive control before stopping was manifest in the bimanual condition as changes in corticomotor excitability, μ (9–14 Hz), and β (15–25 Hz) oscillations over sensorimotor cortex. Together, our results favor the recruitment of a single inhibitory stopping mechanism with the net behavioral output depending on the levels of action-specific motor preparation.

SIGNIFICANCE STATEMENTResponse inhibition is a core function of cognitive flexibility and movement control. Previous research has suggested separate mechanisms for selective and global inhibition, yet the evidence is inconclusive. Another line of research has examined the influence of preparation for action stopping, or what is called proactive control, on stopping performance, yet the neural mechanisms underlying this interaction are unknown. We combined transcranial magnetic stimulation, electroencephalography, electromyography, and behavioral measures to compare selective and global inhibition models and to investigate markers of proactive control. The results favor a single inhibitory mechanism over separate selective and global mechanisms but indicate a vital role for preceding motor activity in determining whether and which actions will be stopped.
The Rab5–Rab11 Endosomal Pathway is Required for BDNF-Induced CREB Transcriptional Regulation in Hippocampal Neurons
Authors: González-Gutiérrez Andrés , Lazo Oscar M. , Bronfman Francisca C.
Published: September 2020

Brain-derived neurotrophic factor (BDNF) is a key regulator of the morphology and connectivity of central neurons. We have previously shown that BDNF/TrkB signaling regulates the activity and mobility of the GTPases Rab5 and Rab11, which in turn determine the postendocytic sorting of signaling TrkB receptors. Moreover, decreased Rab5 or Rab11 activity inhibits BDNF-induced dendritic branching. Whether Rab5 or Rab11 activity is important for local events only or for regulating nuclear signaling and gene expression is unknown. Here, we investigated, in rat hippocampal neuronal cultures derived from embryos of unknown sex, whether BDNF-induced signaling cascades are altered when early and recycling endosomes are disrupted by the expression of dominant-negative mutants of Rab5 and Rab11. The activity of both Rab5 and Rab11 was required for sustained activity of Erk1/2 and nuclear CREB phosphorylation, and increased transcription of a BDNF-dependent program of gene expression containing CRE binding sites, which includes activity-regulated genes such asArc,Dusp1,c-fos,Egr1, andEgr2, and growth and survival genes such asAtf3andGem. Based on our results, we propose that early and recycling endosomes provide a platform for the integration of neurotrophic signaling from the plasma membrane to the nucleus in neurons, and that this mechanism is likely to regulate neuronal plasticity and survival.

SIGNIFICANCE STATEMENTBDNF is a neurotrophic factor that regulates plastic changes in the brain, including dendritic growth. The cellular and molecular mechanisms underlying this process are not completely understood. Our results uncover the cellular requirements that central neurons possess to integrate the plasma membrane into nuclear signaling in neurons. Our results indicate that the endosomal pathway is required for the signaling cascade initiated by BDNF and its receptors at the plasma membrane to modulate BDNF-dependent gene expression and neuronal dendritic growth mediated by the CREB transcription factor. CREB is a key transcription factor regulating circuit development and learning and memory.

LOBIZMAS UŽSIENIO ŠALYSE IR LIETUVOJE: TEISINIO REGULIAVIMO IR INSTITUCIONALIZACIJOS PROBLEMOS
Authors: Lukošaitis Alvidas
Published: September 2020

Straipsnyje nagrinėjamas lobizmo teisinis reguliavimas ir institucionalizacija užsienio šalyse ir Lietuvoje. Teisėtas lobizmas vertinamas kaip skaidraus politinio proceso sąlyga ir reikšminga korupcijos prevencijos priemonė1. Remiantis užsienio šalių lobizmo teisinio reguliavimo patirtimi, bandoma atsakyti į klausimą, kodėl teisėto lobizmo institutas yra neefektyvus arba neveikia Lietuvoje. Pagrindinės tiriamos problemos – teisinio reguliavimo netobulumas, politinės sistemos ir sprendimų priėmimo proceso specifika, sociokultūrinio konteksto bruožai, – kaip veiksniai, apsunkinantys teisėto lobizmo institucionalizaciją. Apibendrinti tyrimo rezultatai leidžia teigti, kad lobizmo institucionalizacija chaotiško pliuralizmo, sektorinio korporatyvizmo ir mutuojančio klientelizmo sąlygomis yra sudėtingas uždavinys, o sociokultūrinių veiksnių visuma teisės normas paprasčiausiai „atmeta“.

Trends in Human Papillomavirus Vaccination in Commercially Insured Children in the United States
Authors: Chen Szu-Ta , Huybrechts Krista F. , Bateman Brian T. , Hernández-Díaz Sonia
Published: September 2020

OBJECTIVES:

The human papillomavirus (HPV) vaccine was recommended in 2006 for girls and in 2011 for boys. The Healthy People 2020 goal for 2-dose HPV vaccination coverage is 80% by age 15 for girls and boys. We used nationwide population-based data to describe trends in HPV vaccination in children.

METHODS:

We conducted a cohort study nested within the MarketScan health care database between January 2003 and December 2017. Children were followed from the year they turned 9 until HPV vaccination, insurance disenrollment, or the end of the year when they turned 17, whichever came first. We estimated the cumulative incidence of at least 1- and 2-dose HPV vaccination, stratified by birth year, sex, and state. In secondary analyses, we evaluated the association between state-level vaccination policies and HPV vaccination coverage.

RESULTS:

This study included 7 837 480 children and 19.8 million person-years. The proportion of 15-year-old girls and boys with at least a 1-dose HPV vaccination increased from 38% and 5% in 2011 to 57% and 51% in 2017, respectively; the proportion with at least a 2-dose vaccination went from 30% and 2% in 2011 to 46% and 39% in 2017, respectively. By 2017, 2-dose HPV vaccination coverage varied from 80% in Washington, District of Columbia, among girls to 15% in Mississippi among boys and was positively correlated with legislation for HPV vaccine education and pediatrician availability.

CONCLUSIONS:

Despite the increasing trends in uptake, HPV vaccine coverage among commercially insured children in the United States remains behind target levels, with substantial disparities by state.

Authors: Sandeep Dubey  , Rukhsana Najeeb  , Arshid Ahmad Sofi
Published: September 2020

Background: Supraclavicular block is a safe, reliable and cost effective technique of providing anesthesia for the upper limb surgeries.

Objectives:  To evaluate the effect of Clonidine and Dexmedetomidine as an adjuvant to Ropivacaine in ultrasound guided supraclavicular block in upper limb surgeries with respect to: Onset of sensory and motor block, Duration of sensory and motor block, Quality of block and Duration of post-operative analgesia.

Materials and methods: The purpose of present study was to compare the effect of addition of clonidine 1mcg/kg vs dexmedetomidine 1mcg/kg to 20ml of 0.5% ropivacaine in ultrasound guided supraclavicular brachial plexus block. A total of 90 patients of ASA I and II, aged 18-60 years, of either gender, undergoing upper limb surgery were allocated to three groups. Each group consisted of 30 patients. They received drugs as under: Group-A (dexmedetomidine group) received 20ml of 0.5% ropivacaine plus 1μg/kg of dexmedetomidine. Group-B (clonidine group) received 20ml of 0.5% ropivacaine plus 1mcg/kg clonidine. Group-C (placebo group) received 20 ml of 0.5% ropivacaine plus 2 ml normal saline.

Results: Onset of sensory block was faster in Group-A as compared to Group-B and Group-C. The difference was statistically significant (p-value<0.05). Onset of motor block was faster in Group-A as compared to Group-B and Group C. The difference was statistically significant (p-value<0.05). Patients of Group-A had significantly longer duration of sensory and motor block when compared with Group-B and Group-C (p-value<0.05). Duration of post-operative analgesia was significantly longer in Group-A as compared to Group-B and Group-C (p-value<0.05). Quality of block was significantly better in Group-A as compared to Group-B and Group-C (p-value<0.05).

Conclusion: Dexmedetomidine prolongs the duration of sensory and motor block, duration of postoperative analgesia and improves the quality of block much more as compared to clonidine when used as an adjuvant to ropivacaine in supraclavicular brachial plexus block.
Monarquía ibérica o Iberia republicana: identidad política e iberismo en la España de la revolución (1868-1873)
Authors: Chato-Gonzalo Ignacio
Published: September 2020

La revolución de 1868, desde su génesis hasta su fin, generó una serie de escenarios en los que las distintas fuerzas políticas se vieron obligadas a adaptar y reconstruir sus identidades partidarias. En esa rápida sucesión de planos y situaciones, el iberismo constituyó un poderoso instrumento que progresistas y demócratas en el inicio, y los republicanos después, vinieron a utilizar en distintos momentos del proceso revolucionario. Un principio que llegó a formar parte sustancial de sus respectivas culturas políticas y que ayudó a definir sus particulares imaginarios colectivos. El proyecto de unión ibérica fue un útil y eficaz compañero de viaje en las complejas trayectorias que estas fracciones políticas tuvieron que recorrer, especialmente en las fases previas de su acceso al gobierno, resultando uno de los ingredientes principales de la idea de revolución que defendieron. Pero también se convirtió en un elemento difícil de articular y de digerir, una vez alcanzado el poder, en la construcción de las nuevas estructuras políticas que tuvieron que acometer. Un incómodo testigo que fue pasando de manos, de los partidos monárquicos a los republicanos, sin que pudieran afrontarse ―y mucho menos cumplirse― los anhelos y sueños que el iberismo prometía: ni una monarquía ibérica ni una Iberia republicana.
O cotidiano de professores e alunos nas aulas de Educação Física: revisão teórica
Authors: Souza Adalberto Dos Santos , Silva Cinthia Lopes da
Published: September 2020

Este trabalho tem como objetivo realizar reflexões sobre o cotidiano escolar de professores e alunos nas aulas de Educação Física (EF), considerando a perspectiva do conceito de “cotidiano” de Michel de Certeau. Nas aulas de EF o conhecimento escolarizado é muitas vezes tratado de um modo impositivo, e ao que tudo indica isto ocorre pelo fato da EF ser uma disciplina que lida com questões relacionadas ao corpo e às práticas corporais, de modo que é frequente os professores de EF desconsiderarem os aspectos simbólicos que os alunos atribuem às aulas e aos seus conteúdos vivenciados. Como procedimentos metodológicos foi realizada revisão de literatura, centrada nas aulas de EF escolar e nos estudos do cotidiano na escola, caracterizando esse trabalho como qualitativo. Foi feito um levantamento bibliográfico para a seleção de textos que apresentassem dados de pesquisa de campo sobre os significados das aulas de EF e o trabalho docente. Para a busca utilizou-se o site google acadêmico e os termos chave: “significados das aulas de Educação Física” e “trabalho docente”, sem a combinação entre si. Chegou-se à conclusão que o cotidiano de professores e alunos na escola é construído e reconstruído de forma dialética. É justamente o contínuo processo de ressignificação das aulas de EF que pode gerar a resistência à tradição de tais aulas, assim como minimizar problemas que afastam os alunos das aulas de EF e da escola.
Música, brincadeira e afeto: possíveis facilitadores da linguagem de crianças com autismo
Authors: Gomes Monteiro Emilene
Published: September 2020

Este artigo versa sobre um estudo bibliográfico, com base no referencial da Psicologia Histórico-Cultural, a respeito da relação entre música, brincadeira e afeto. Considera-se a música e a brincadeira, permeadas por afetos, como possíveis meios potencializadores do desenvolvimento de crianças com autismo, facilitando desse modo sua linguagem. A mediação pedagógica e o possível estímulo psicológico, afetivo e social, propiciado por esse contato, se apresentam como potentes meios para esse propósito. Tal movimento se propõe como caminho alternativo às apropriações dessa criança na aquisição e ampliação da linguagem e também aos processos inclusivos no contexto educacional.
A Pós-Graduação Stricto Sensu no Brasil: um estudo a partir dos documentos legais
Authors: Delgado Bueno da Silva Nathália , Da Fonseca Brandão Carlos
Published: September 2020

O presente estudo tem por objetivo identificar os direcionamentos destinados à pós-graduação, scricto sensu, no Brasil no decorrer dos anos. Este nível de ensino emerge no país de maneira regulamentada na década de 1960, garantindo-se atualmente como um Sistema de ensino, possuindo representatividade e status acadêmico frente a pós-graduação lato sensu. O estudo é de caráter bibliográfico e documental, tomando por base o Parecer n. 977 de 3 de dezembro de 1965 e os Planos Nacionais de pós-graduação (PNPG), que de maneira diretiva interferiram para que este nível de ensino se consolidasse. Os documentos refletem as pretensões e necessidades da época em que englobam, estando articulados ao contexto social, político e econômico. Essa reflexão pode ser constatada pois há linearidade na pós-graduação em determinados ciclos, como sua iniciação legal e a necessidade de estabelecer diretrizes formais para unificar os programas; posteriormente, as intenções em aferir a qualidade da expansão, e assim, a manutenção de um Sistema, que hoje é tema de diversas discussões, seja sobre sua avaliação, seja sobre sua organização e conjuntura.
Desorption and re-adsorption of PAHS on aircraft soot surface
Authors: Lan Nguyen Mai
Published: September 2020

Polycyclic Aromatic Hydrocarbons (PAHs) in aircraft soot are capable to distribute in the gas phase and particulate phase in chemical transformations in the atmosphere. The desorption of PAHs from the soot surface is a preliminary step in the study of the reactivity of particulate PAHs. The desorption kinetics of PAHs are measured from soot samples to determine desorption rate constants for different PAHs as a function of temperature and the binding energies between PAHs and soot. The kinetics of degradation of particulate PAHs were studied in the flow reactor. The soot samples previously deposited on a Pyrex tube are introduced into the reactor along its axis and the concentrations of PAHs adsorbed on soot are determined by the High-Performance Liquid Chromatography (HPLC) as a function of the desorption time. The results show a correlation between the size of PAHs and the thermodynamics of desorption: with the PAHs have the same number of carbon atoms, their energies of desorption are very similar and increase with this number. The activation energies EA and the number of carbon atoms in PAHs have a linear correlation. It is consistent with the additivity of the laws Van der Waals. The similarity between the activation energies of desorption of PAHs and the corresponding sublimation enthalpies is consistent with the similarity between the graphitic structure of soot and the structure of PAHs.

Published: September 2020

The relevance of the study is determined by the implementation of housing reforms in Volgograd region and the need to assess their effectiveness. The object of the study is the public opinion about the current state of housing and communal services in Volgograd region. The purpose of the work is to identify the degree of satisfaction of citizens with tariffs and quality of services provided by property management companies. The methodology includes structural and statistical analysis as well as the synthesis of the results obtained from the formation of an objective and unambiguous assessment of the quality and tariffs of housing services in the region. The results obtained indicate a low level of satisfaction with the services of property management companies, herewith citizens are more dissatisfied with the level of price tariffs, while the level of satisfaction with the quality of housing and communal services is at a slightly higher level. According to the results of the study, possible directions for the improvement of the quality of services provided have been identified. The ways to reduce price tariffs by means of the optimization of funding sources by means of an effective mechanism development for public and private partnership have been suggested. In addition, the authors have determined that the control of the efficiency of residential and utilities services organizations should be transferred to the company presented by members of housing owners’ associations and other socially oriented non-profit organizations. The results of the study can be used to identify the priority areas for the improvement of housing and communal services in Volgograd region.
Project and Program Management Under Conditions of Strategic Planning Modernization
Authors: Pazdnikova Natalya , Pazdnikov Ilya
Published: September 2020

The modernization of strategic planning in the Russian economy is caused by the existing situation and problems of public administration in the conditions of the formation and implementation of projects initiated by the government. The main purpose of this article is to demonstrate the need to deal with the issues connected with the emergence of a huge diversity of projects that will provide a clear understanding of the role of strategic mechanisms applied in the territories of the Russian Federation. For the solution of this goal, originally, the genesis of the formation of the national project and program management has been carried out. The contribution of the Soviet school to the development of the state project development as well as studies of the modern stage of strategic planning has been analyzed. The authors suggest a hypothesis that project and program management is a key component of the government policy. The effectiveness of project management can be studied by means of the methods of strategic management. The authors conduct the research on the basis of comparative analysis, normative and expert methods which allow estimating the characteristics of projects and programs on the basis of the portfolio ideology. In addition, the approach to the formation of the economic mechanism of the portfolio to the partnership of project participants and program management on the basis of the interaction of system elements have been proposed. The obtained results of the study of foreign and domestic experience allow us to suggest a classification of social projects and programs within the portfolio partnership of participants and to analyze the current statistics. The results of the study show an increase of quantitative and qualitative components of project and program management practice of strategic changes. The main results prove that over time the strategic change in project activity, contradictions are observed and inconsistencies in state requirements and practices are found that need effective decisions.
AS FACULDADES DA MIMESE, IMAGINAÇÃO E MEMÓRIA NA INFÂNCIA: O ENTRELAÇAR DO AMOR E DO PENSAMENTO
Authors: SALGADO MARA , VAZ ALEXANDRE FERNANDEZ
Published: September 2020

RESUMO: O objetivo deste artigo é apresentar os resultados da pesquisa acerca do entrelaçamento do amor e do pensamento na infância em Theodor W. Adorno, cujas faculdades da mimese, imaginação e memória marcam a infância como uma experiência de outra ordem da razão, mais mimética, imaginativa, que alimenta a memória da natureza no humano, contudo, sem isentar-se das forças históricas coercivas que constituem as condições objetivas da vida. Privilegiou-se como método da investigação teórica a análise dos conceitos de mimese, imaginação e memória em suas relações com a infância e com a base pulsional que possibilita o movimento do amor, fundamentando-se em Adorno e seus interlocutores da Teoria Crítica da Sociedade, em especial Walter Benjamin, e na Psicanálise freudiana. Tais faculdades operam no pensamento por meio de mecanismos psíquicos de defesa da consciência que entrelaçam os processos mais primitivos da natureza humana ao desenvolvimento dos processos superiores que a cultura possibilita.

A FOTOGRAFIA AGENCIANDO LINHAS DE VIDA NOS COTIDIANOS ESCOLARES
Authors: CARVALHO JANETE MAGALHÃES , ROSEIRO STEFERSON ZANONI , LOURENÇO SUZANY GOULART
Published: September 2020

RESUMO: O artigo objetiva pensar com crianças, junto a fotografias, a vida que insiste em transbordar em meio às vivências em uma escola pública de ensino fundamental. Diante do ataque capitalístico que sofrem os corpos em um cenário em que a vida é radicalmente empobrecida, discute a possibilidade de uma leitura fotográfica ao inverso dessa força de contenção, acreditando que a vida e a resistência antecedem as tentativas de controle. Utiliza como abordagem metodológica as redes de conversações com crianças, disparadas por fotografias, entendendo que a fotografia produz e força o deslocamento de pensamentos e encontros, pois cria superfícies vibráteis, produz reencontros de tempos e espaços, reinventa o passado e ilumina o presente, podendo suscitar uma potência e uma multiplicidade de criação de sentidos que vivem e morrem entre a intenção do fotógrafo e a imprevisibilidade-impossibilidade de uma única visão da fotografia. Conclui que as crianças buscam expressar linhas de vida que pulsam na relação de seus corpos com outros corpos e incorpóreos em seus cotidianos como um impulso para o movimento de criação.
Precarious spaciality of refugees in Brazil

Published: September 2020

This article aims to explore the importance of the different types of displacement in constituting the differences of two collective of refugees. Influenced by Ingold (2007) and the importance he gives to the paths, trajectories and lines in phenomenological terms, now intending to investigate how the different migratory paths, established in conjunction by groups of people, imply the production of differences. This spatial dimension is especially evident in the case of refugees we have begun to study: varied paths of space routes caused by reasons unrelated to the will of the refugees. We have analyzed two cases of refugees/immigrants: Haitians and women refugees in São Paulo (mainly Congolese). These cases are linked to distinct spatial trajectories in the present.

Produtos plásticos são ideais para um modelo de consumo rápido e barato, por outro lado, o seu uso momentâneo gera demasiado descarte de resíduosepode ocasionarproblemas ambientais. Neste contexto, esse trabalho objetivouproduzir um compósito polimérico baseado em materiais pós-consumo, envolvendo polipropileno e farinha de madeira, bem como avaliar as propriedades das formulações desenvolvidas. Através da reciclagem mecânica de polipropileno (PP) pós-consumo (resíduo urbano) e da farinha de madeira (resíduo do processamento de Medium Density Fiberboard- MDF) proveniente da indústria moveleira, desenvolveu-se um compósito polimérico, com diferentes teores dos constituintes em suas formulações, através dos processos de injeção e moldagem por compressão a quente. As propriedades dos compósitos obtidos foram avaliadas através da realização de ensaios físicos e mecânicos de granulometria, espessura, resistência à tração e flexão, absorção de água e índice de fluidez e morfológico - microscopia eletrônica de varredura (MEV). Através dos resultados obtidos, foi possível destacar que a incorporação da farinha de madeira ao compósito, proporcionou ao material o aumento da resistência à flexão e o aumento da rigidez, entretanto, a resistência à tração diminuiu. O índice de absorção de água foi maior no compósito que continha maior proporção de farinha de madeira em sua formulação. Já as micrografias evidenciaram a adesão das fibras à matriz e a formação de bolhas nas imagens de seção transversal.

BHI + v2 salts media v1
Authors: Haines Matthew
Published: September 2020

Vibrio natriegens grows exceptionally well in BHI + v2 salts media (link). Furthermore, this media has been used multiple times in the literature for culturing this organism. However, care must be taken when preparing this media not to autoclave v2 salts and BHI together. This protocol utilises a 10x v2 salts buffer to achieve this.
Access to healthcare services for the Roma and undocumented migrants in the EU in light of the Covid-19 pandemic
Authors: Varga Bernadett Mária
Published: September 2020

Background. The rising number of the EU Roma citizens from the CEE countries, non-EU Roma citizens from the Western-Balkans, and of undocumented migrants in the European Union makes it interesting to see that most of them face barriers when accessing health services [with a European Health Insurance Card (EHIC)] or have no health coverage at all [no legal entitlement]. European migrant health policies are seemingly well structured and responsive to the needs of migrants, however, results of recent studies raise the question whether the legislations are responsive enough to the needs of the Roma and undocumented migrants when accessing health services. Given the circumstances of the Covid-19 pandemic these groups are now at an increased risk and they might not be able to understand how the virus transmits and how they can protect themselves from it.  Methods. Literature review focusing on the access to health services and migrant health policies in the EU and the UK was carried out. The target groups of this research were Roma citizens and third-country national undocumented migrants residing in the European Union. Results. In theory the legal entitlement for accessing healthcare for migrants in general is satisfactory, while in practice these groups face difficulties, such as prejudice, discrimination and other barriers (language, logistical) when approaching health services. Migrants lack trust in the health system and the healthcare professionals, and are not aware of their fundamental rights to healthcare either.  Conclusions. Legal entitlements for EU migrant citizens do not differ within EU countries but they significantly vary for undocumented migrants Europe-wide and there seems to be a mismatch between the legal entitlements for undocumented migrants in theory and their implementation in practice. Given the circumstances of the pandemic these groups are at an increased risk and therefore their health inclusion through health literacy programs should take place, as well as health workers should be trained on diversity in order to establish diversity adapted EU health systems. Seeking adaptive practices to establish cultural diversity within the healthcare settings, and introducing the universal health coverage scheme Europe-wide in order for undocumented migrants and EU citizens without employment to benefit from proper healthcare services is encouraged and necessary.
Teaching Russian students to analyze the syntactic structure of sentences in modern Chinese (Mandarin)
Authors: Skvortsov Arseniy V. , Malykh Oksana A.
Published: September 2020

The paper deals with methodological issues of teaching senior students of language universities to analyze the syntactic structure of sentences in modern Chinese at the phrase level. The technology of teaching Russian students to analyze the syntactic structure of sentences in modern Chinese is presented in the following stages: 1) theoretical explanation of the classification of phrases in modern Chinese and methods of mastering this phenomenon by students; 2) introduction to five different ways of syntactic analysis of sentences at the phrase level; 3) presentation of features of the analysis "from small to large"; 4) improvement of skills of independent analysis of offers by students using the specified method. Much attention is paid to the order of establishment of relations between lexical items in phrases, combined with each other semantically. At the same time, in the developed technology, it is recommended to analyze the group of subject and predicate separately, performing an analysis from right to left. When faced with more difficult cases - long complicated sentences, the authors recommend analyzing the sentence in both directions, both from left to right and from right to left. Russian translation is recommended when determining the type of a phrase in Chinese. It is recommended that you translate the phrase into Russian, set its type in Russian, and then make a conclusion about the type of this phrase based on the typology used in Chinese. The existing limitations of using this method are discussed. As the main method of analyzing the syntactic structure of Chinese sentences, the analysis "from small to large" is chosen as the most convenient in implementation and allows parsing long complicated sentences.
Constructions with parataxis and homogeneous parts in poetical text
Authors:   Taras Shevchenko national University of Kyiv, Darchuk Natalia
Published: September 2020

The work considers peculiarities in conducting of automated syntactic analysis (ASA) on basis of poetical texts and as result studying the features of linear structure of Ukrainian texts, in particular, texts with constructions with parataxis and homogeneous parts. The process of text analysis includes two stages: the first stage starts with automated syntactic analysis of hierarchical structure of text, which finally builds a dependency tree. On the second stage the graph received as result of automated analysis specifies information on type or model of a sentence, in particular, with available constructions with parataxis homogeneous parts. The purpose of the work from linguistic standpoint is the analysis of parataxis/homogeneous parts in poetical texts and their relations to the content. The study of texts (1600 sentences) showed that constructions with parataxis can build three groups of relations with: homogenous parts, non-homogenous and a combination of both parts. Analysis of constructions with parataxis with available dominating syntactical level demonstrated specific features of poetical structure of texts of four analyzed authors Vinhranovskyi, Drach, Moisiienko and Stus. Project follow-up is viewed in the study of correlation between syntactical and semantic analysis of text structures, since the form of poetical text specifies of how the poetical language is shaped in sense of qualitative features. Study of construction with parataxis within both a single author’s style and an array of other authors’ styles presents interest and future prospects from the standpoint of carrying qualitative semantic analysis of parataxis with available homogenous items. It is possible since all variants of lexical meaning in the Corpora (their number reaches over 120 K) are automatically marked with special codes of taxonomic classification and with code showing relation to some or other taxon. This technology makes possible to conduct a comprehensive analysis of constructions with parataxis, to create lists and sort out relations of such type of constructions within the range of a dependency tree to detect and identify common and miscellaneous features in the structure of parataxis as a parameter of an individual writing style of a single author.

Placental respiration in a normal state and following bleeding in the mother
Authors: Sheinis L.
Published: September 2020

As for normal placental respiration, the author's research only confirmed the results already obtained earlier by Cohnstein and Luntz: it is known that the fetus borrows the oxygen it needs from the mother's blood and, in fact, the blood of the umbilical vein contains more oxygen, than the blood of the umbilical artery, while carbon dioxide, on the contrary, predominates in this latter.
Pre ve Post Embriyonik Dönemdeki Civcivlerin Kalp Ventrikülleri ve Purkinje Hücrelerine Histokimyasal Bir Yaklaşım
Authors: TURGAY İZZETOĞLU Gamze , TURAN ÖZGAN İnci , YALÇIN Servet
Published: September 2020

Bu çalışmada embriyo ve civcivlerde kalp ventrikül duvarı, iletim sistemi ve Purkinje hücreleri üzerine yumurta ağırlığı ve damızlıkların gelişim hızının etkisinin araştırılması amaçlanmıştır. Bu amaçla hızlı gelişen Ross 308 ve yavaş gelişen Hubbard JA genotipindeki damızlık sürülerinden elde edilen tavuk yumurtaları hafif (64±1g) ve ağır (72±1g) olarak iki gruba ayrılmıştır. Kuluçkanın 18. ve 21. günlerinde alınan kalp ventriküllerinin boyuna kesitlerine farklı histokimyasal boyalar uygulanarak, ventrikül duvarı, iletim sistemi ve Purkinje hücreleri incelenmiştir. Genotipin gelişim hızı ve yumurta ağırlığı, kalp ventriküllerinde histoloji açısından herhangi bir farklılığa yol açmamıştır. Ventrikül duvarlarında miyofibriller arası boşluk oluşumu ve kollajen-miyofibril yoğunluk farklılığı görülmüş, bu durumun embriyonik gelişimden kaynaklandığı düşünülmüştür. Histolojik bir çalışmada farklı histokimyasal boyaların kullanılması, organizmaların embriyonik gelişimlerinin takibinde farklı yapıların incelenmesine olanak sağlamaktadır.
Research Methodology in Gastronomy in the Scientific Field of Tourism
Authors:   Universidade do Vale do Paraíba. São José dos Campos, SP, Brasil., Ferro Rafael Cunha
Published: September 2020

This exploratory and descriptive paper characterized the methodological procedures adopted in the master's theses produced in the scientific field of tourism with themes focused on gastronomy between 2001 and 2016. For this purpose, 61 theses at the CAPES Thesis Bank were treated employing content analysis from categories based on referential authors. Exploratory and descriptive researches, with a qualitative approach, were the most recurrent. The main research strategies adopted are case studies and ethnography, while the most recurrent techniques for data collection were interviews and document analysis. Many authors did not inform about data analysis techniques. The results agreed with the scientific field of tourism in Brazil, but not with the international scenario. There are no trends of change regarding the methodological procedures, which may indicate that Gastronomy as a tourism research theme does not move towards a maturation stage.
La taxatividad de las causales de anulación de un laudo arbitral
Authors: Gaibor Arteaga Paola , Del Salto Ubidia Gabriela
Published: September 2020

La acción de nulidad en contra de los laudos arbitrales surge en el Ecuador como mecanismo de control judicial al arbitraje al ser este un método alternativo de resolución de controversias con potestades jurisdiccionales. Ante interpretaciones amplias de las causales existentes de la acción de nulidad previstas en la Ley de Arbitraje y Mediación, la Corte Constitucional emitió en el 2019 dos sentencias que limitan la aplicación de las causales, ratificando la taxatividad de las mismas. Por esta razón, el presente artículo busca realizar un análisis del régimen jurídico de la acción de nulidad en el Ecuador y establecer si las causales deberían ser taxativas o no. En este sentido, en primer lugar, se expondrá la acción de nulidad y su rol en el arbitraje. A continuación, se analizarán diversas decisiones que reflejan la interpretación, el alcance y la aplicación de las causales de anulación. Una vez establecidas las diversas posiciones que ha tomado la jurisprudencia ecuatoriana, se ratificará la taxatividad de las causales de anulación de laudos al ser una característica intrínseca de la excepcionalidad de dicha acción. Finalmente, se pondrán en consideración causales no previstas en el ordenamiento jurídico ecuatoriano, pero que deben ser tomadas en cuenta por el rol del Estado a nivel internacional.
Direito Penal do inimigo e política brasileira de encarceramento em massa
Authors: Arbage Lucas
Published: September 2020

Este artigo tem como objetivo discorrer acerca do Direito Penal e a teoria do Direito Penal do Inimigo, proposta por Günther Jakobs, num aspecto histórico-crítica, à luz do contemporâneo Direito Penal crítico. Para tanto, analisa-se a atual conjuntura da política criminal brasileira, bem como da teoria do direito penal do inimigo. Expõe-se os malefícios de uma política criminal de caráter exclusivamente repressiva, sua relação com a mídia e os riscos decorrentes das leis que são criadas em caráter emergencial no intuito de solidificar o simbolismo do direito penal e a subcidadania, ferindo direitos fundamentais. Debatem-se os principais aspectos da teoria do direito penal do inimigo, sendo explicitadas algumas das suas críticas. Por fim, conclui-se que a Justiça Penal deve-se basear num posicionamento político-criminal minimalista e garantista, condizente com o Estado Democrático de Direito, com intuito de prevenção geral dos crimes e vedando as penas cruéis, utilizando-se das penas e medidas alternativas. A metodologia empregada foi a pesquisa bibliográfica e documental, composta pela análise de documentos oficiais, do ordenamento jurídico e doutrina.
