Authors: Baghianimoghadam Behnam , Arabzadeh Aidin , Fallah Yousef 
Published: August 2021

Introduction: Chondroectodermal dysplasia (Ellis–van Creveld syndrome (EVC)) (OMIM: #225500) is a rare skeletal dysplasia with unknown exact prevalence. EVC patients may have abnormal skeletal and extra skeletal symptoms. We report a case of EVC patient and review previous cases reported in Iran.Materials and methods: The patient was a 30 years old woman referred to our hand clinic for an extra finger in both hands. She was born to a consanguineous marriage. The patient had a history of bilateral valgus deformity of the knees, for which she underwent proximal tibial and distal femoral osteotomy. Upon examination, the patient had bilateral polydactyly and brachymetacarpia with hypotrophic fingernails. She was about 120 cm tall and had acromesomelic type dwarfism. Oral examination revealed serrated incisal margins, dental transposition, a diastema, conical teeth and, enamel hypoplasia. In the radiographic examination of upper extremity, postaxial polydactyly and polymetacarpia, enlarged distal radius, and fusion of capitate and hamate were seen. We searched online databases (Pubmed, Scopus, Google Scholar) and found 14 Iranian papers with 21 reported patients (there was no time limit). We reviewed available clinical and genetic data and the geographic origins of patients.Results: 14 articles reporting 22 EVC patients (including our patient) from Iran have been published in Persian and English (7 in Persian and 7 in English). All patients presented with characteristic EVC symptoms but were diagnosed at a relatively late age, 18 patients were born to consanguineous marriages.Conclusions: It seems that based on these studies, it is possible to identify some families with this genetic mutation. We can warn such families of the dangers of consanguineous marriage through genetic counseling before marriage. In addition, by identifying families with such problems, we can detect such anomalies in the baby earlier with more careful prenatal care.

Introducción: El tratamiento del valgo severo es complejo. El abordaje externo descrito por Keblish es ventajoso para tratar estas deformidades. Evaluamos nuestros resultados utilizando un abordaje externo en artroplastias de rodilla con genu valgo severo.
Materiales y Métodos: De 795 artroplastias primarias realizadas entre enero de 2012 y marzo de 2020, analizamos 40 que tenían un abordaje externo. Todos los pacientes tenían una deformidad en valgo >20° y un ligamento colateral medial suficiente. Se incluyó a 33 mujeres (3 bilaterales) y 4 hombres, el promedio de edad era de 71 años. La causa fue fundamentalmente osteoartrosis (82%). La deformidad prequirúrgica era de 27°. Las mediciones preoperatorias eran: KSS 15 (rango 5-42) y KFS 17 (rango 0-40). El tiempo promedio de cirugía fue de 91 minutos y el seguimiento, de 37 meses.
Resultados: El ángulo femorotibial posoperatorio fue de 6,2° (rango 4-40), el KSS posoperatorio fue de 79 (rango 46-95) y el KFS, de 82 (rango 60-100). Hubo tres complicaciones (7%): una infección, un mal posicionamiento de componentes y uno de neuropraxia peronea.
Conclusiones: En la artroplastia de rodilla por genu valgo, este abordaje permite restituir el eje femorotibial, lograr una adecuada estabilidad de la prótesis, aun con implantes sin mayor grado de constreñimiento, con una tasa de complicaciones equiparable a la de otras técnicas.
Representações e identidades juvenis na sociedade atual: padronizações e estereótipos
Authors: Lima Crislaine Pereira de , Pátaro Cristina Satiê de Oliveira , Polato Adriana Delmira Mendes 
Published: August 2021

presente texto aborda o conceito plural das juventudes, seus papéis e vozes sociais na modernidade, bem como as imbricações entre os elementos que participam da constituição desses sujeitos,tais como relações sociais, cultura, lazer, educação, considerando os princípios de instrução e formação cidadã, condições econômicas, trajetória, identidades e protagonismos. A partir de uma abordagem interdisciplinar, que coaduna interpretações da sociologia, da antropologia, da filosofia e do dialogismo do círculo russo de Bakhtin, nosso objetivo consiste em analisar um artigo intitulado “Os jovens nem-nem” publicado na revista “Isto é” online, que mobiliza um discurso sobre os jovens que não estudam e também não trabalham. Na análise do enunciado, buscamos compreender como ele reflete e refrata valorações próprias de partidas ideológicas que buscam analisar o papel social do jovem a partir de uma interpretação de base socioeconômica. Os conceitos de signo ideológico, ideologia, vozes sociais e consciência socioideológica são mobilizados na análise, na medida em que entendemos que o enunciado é constituído por valorações que sustentam relações sociais, interpretações de mundo e das vivências sempre a partir de posicionamentos ideológicos. Como resultado, apresentamos a importância do dialogismo na análise dos discursos que ecoam perspectivas sócio-históricas, culturais e ideológicas sobre a temática das juventudes, a destacar como fundamental a presença de vozes sociais e valores que servem a representações refratárias, ou à multiplicidade de identidades e trajetórias dos jovens, de modo a clarificar como os discursos constituem e ao mesmo tempo são constituídos pelas relações sociais, sendo sua interpretação subsidiária de prospecções e rupturas de ordens instaladas.
A Educação Popular na Venezuela (A Missão Ribas sob a Presidência de Hugo Chávez)
Authors: Campos Alzira Lobo de Arruda , Baseio Maria Auxiliadora Fontana , Oliveira Deise da Rosa 
Published: August 2021

O significado de “educação popular”, tornado central nas políticas dos estados ocidentais no século XIX, é analisado no exemplo venezuelano, como um dos elementos principais do regime bolivarianista de Hugo Chávez, que propunha democratizar o acesso de toda a população ao sistema de ensino, por meio das chamadas “Missões Bolivarianas”, das quais selecionamos a “Missão Ribas”. O objetivo principal é o de contribuir para o conhecimento das relações da “educação popular” com a práxis de uma campanha de forte impacto, tanto na realidade objetiva da sociedade, quanto no subjetivismo ideológico da fidelidade aos princípios tidos como fundamentos da educação bolivariana. O espaço geográfico é o da Venezuela, em geral, e o de Caicara del Orinoco, em particular, uma cidade do interior venezuelano, na qual observamos a ação direta da política educativa bolivariana, efetivada em salas de aula, junto a professores e alunos.
A Educação na Encruzilhada: O Pensamento Conservador da Escola Sem Partido versus o Pensamento Libertador de Paulo Freire
Authors: Lopes de Sousa Rafael , Dias Luiz Antonio 
Published: August 2021

: A primeira proposta do Movimento Escola Sem Partido (MESP) foi elaborada em 2004. Uma década depois, com a eclosão de mobilizações de movimentos conservadores Brasil afora, suas pautas ganham visibilidade midiática e angariam o apoio de parlamentares e de partidos de direita. No ano de 2016, em meio aos acontecimentos que reduziram a discussão política brasileira ao maniqueísmo direita versus esquerda, bem versus mal, patriotas versus impatriotas, as propostas do MESP serviram de baluarte nas discussões do impeachment da presidente Dilma Rousseff. O objetivo deste artigo é discutir os desdobramentos desses acontecimentos para a vida educacional dos brasileiros, seja em relação à ação docente, seja em relação à formação das próximas gerações, particularmente no que diz respeito às propostas de controle das atividades docentes conforme propugnado no projeto de lei nº 193/2016, de autoria do senador Magno Malta do Partido Liberal (PL) do Espírito Santo.
ESTIMATION OF THE DISTANCE BETWEEN STATIONS OF OVERTAKING TRAINS WHEN ORGANIZING A MIXED HIGH-SPEED, PASSENGER AND FREIGHT TRAFFIC ON A RAILWAY LINE
Authors: WANG Y. B. 
Published: August 2021

Purpose. This paper presents the calculation method and result of reasonable station spacing in the organization of mixed high-speed passenger and freight transportation, at different speed combinations and different types of train schedules.
Methodology. By using the principle of the shortest distance between stations, this paper analyzes the possible layout of passenger and freight trains running at different speeds between Brest and Moscow, and work out the optimal distance between overtaking stations. According to the shortest distance between stations, the blocking method with four-digit automatic should be used when the maximum speed of the passenger train is 250 km/h. The crossing scheme for different types of trains is determined, and the train schedule period (TDS) of each scheme is determined. Calculate the appropriate distance between stations that had been passed through with different trip intervals according to the characteristics of the passing passenger and freight trains. By adopting simulation analysis, the influence of different number of trains and their composition on the station spacing is simulated to work out the reasonable railway station spacing for passenger and freight train with a speed of 250 km / h.
Findings. In the case of passenger and freight traffic with the speed of 250 km / h, the optimal distance for stations between Brest and Moscow should be around 35 km. In order to make effective use of the existing infrastructure and achieve maximum transit capacity of the railway, it is recommended to increase the speed of the low priority trains.
Originality. The distance between stations on a line will affect the number of stations on the entire line, as well as the maximum train speed and the number of train pairs. Excessive or insufficient station spacing will affect the transportation capacity and efficiency. Therefore, reasonable station spacing will determine the number of trains and the maximum speed of each train for both passenger and freight.
Practical value. This paper proposes a method to estimate the reasonable spacing between crossing stations, which can ensure the effective utilization of the capacity of railway sections when high speed passenger trains on existing lines are running at speeds of up to 250 km/h.

Evidence-Based Development of Doctoral Education: The Landscape of Doctoral Students' Experience Research
Authors: Zhuchkova S. V. 
Published: August 2021

Regular surveys of doctoral students on their career trajectories, satisfaction with the program and the learning process, with the organization of supervision, etc. are widespread in leading foreign universities. The results of such surveys are used to improve programs and assess the effect of the introduced measures. In Russia, however, there is a lack of empirical data on the doctoral students’ experience, which makes it impossible to identify and address the reasons for the low performance of the Russian doctoral education observed over the past few years. To support the discussion about the need for such monitoring surveys in Russia, this article presents the results of an analysis of open information from the websites of about 150 foreign institutions that organize doctoral student surveys at the national, cross-university, and institutional levels. The presented review shows how actively doctoral education data collection takes place in the USA, Canada, Australia, and the UK, where there are one or more large-scale projects stimulating the collection of data from several universities, and how the results of such research are used by universities, employers, and applicants. On the example of topics related to the motivation for entering doctoral programs, to the career trajectories of doctoral students, and to the organization of supervision, it is discussed how the described research practices can be used for the evidence-based development of Russian doctoral education.
Individual Academic Productivity vs New Managerialism in Academic Research
Authors: Niyazova M. V. 
Published: August 2021

The paper considers individual academic productivity and the new managerialism in academic research as a set of social relations, common and opposite interests of a scholar and a university. The balance of interests is a necessary condition for regulating the contradictions among participants in public relations, including academic research. Reforming higher education results in new managerialism spreading wider and in scientific results paid attention to. The increasing accountability with a lack of mutual trust and information asymmetry creates the illusion of an imbalance of academic researchers’ interests in favor of management. The power potential of the new managerialism can become an instrument of both pressure and encouragement of individual academic productivity. As is shown in our review, this productivity, mainly published papers, is influenced by the principles of its assessment. The evolution of approaches to the academic results promotion provides a large variety of criteria for the selection of indicators to assess scientific activity. The game theory allows to reduce this variety to one common ground, where winning is considered to be the basis of relationships in academic research. As a result, there is a matrix model of four strategies – the extreme forms of scholar-and-management relationship manifestation within the system of academic research. Only one of these strategies means a balance of interests and long-term cooperation, the other three imply the contradiction of individual academic productivity vs the new managerialism and are short-term. The use of winning in a game as a basis and criterion of assessment for the individual academic productivity normalization contributes to opportunistic behavior neutralization. The author makes the conclusion that the type of strategy affects the combination of simple and qualitative indicators and professional expertise when assessing scientific results. It is reasonable to choose the indicators of assessment according to the most balanced strategy of regulating the contradictions among participants in academic research.

Deployment the Spoke of a Large-Sized Transformable Refl ector Using a Sequential Optimization Algorithm
Authors: Kabanov S. A. , Kabanov D. S. 
Published: August 2021

The use of large-sized opening reflectors close-packed in spacecraft is associated with spreading the spokes at a given angle, extending the fragments of the spokes and adjusting the shape of the radio-reflecting mesh. The problem of optimizing these processes with automatic output of the reflector to the deployed working state is urgent. The optimal control problem of spreading spokes of a large-sized space-based reflector with respect to bending vibrations is investigated in the article. The optimization process is complicated by ensuring convergence of iterative procedure for control finding. The bending vibrations of the spokes complicate the task of spreading. That makes it difficult to fix spokes when reaching the stops. In this paper the mathematical model of spoke dynamics is improved with respect to spoke’s bend change in length and in time, the model takes into account the presence of stop and retainer devices and an actuator. It is proposed to consider a hierarchy of two target composed functions and develop an algorithm for sequential optimization for a smooth exit to the stops. It is suggested to include the terminal condition for the angular spreading rate in the first criterion. A study was carried out using mathematical simulation for the process of turning the spoke by a given angle at small values of the angular velocity at the final moment of time taking into account bending vibrations. The exact values of the weight coefficients included in the target composed functions are found. Weight coefficients influence on transient processes is investigated. The performance of the algorithm was checked when the value of the optimization interval was changed. The comparison of the results of simulation modeling with control options using the PID controller, application of an algorithm with a predictive model and an algorithm with optimal correction of the control structure, revealed by means of the maximum principle, was carried out. The results of simulation modeling foe spokes spreading process using the sequential optimization algorithm demonstrate the achievement of the required accuracy with permissible tolerance residual vibrations. The developed algorithm of sequential optimization forms control in a real time and it is recommended to use it in more complex solutions under random disturbances using measurement process and optimization of observation intervals.

En los años recientes las empresas sustentables han sido un gran auge en cuanto a inversión y medidas sostenibles por las mismas, es por ello por lo que varios inversionistas han buscado conformar sus portafolios de inversión con empresas sustentables. Por sustentable se entiende como el proceso que busca lograr una prosperidad económica y el equilibrio entre el medio ambiente y el uso de los recursos naturales. El S&P/BMV Total México ESG Índex de la Bolsa Mexicana de Valores agrupa a varias empresas que poseen las mejores prácticas en desempeño ambiental, social y de gobierno corporativo, esto con el objetivo de formar una economía sólida, que sea adecuada al contexto actual y las necesidades del futuro. El estudio de la presente investigación se enfoca al análisis de empresas que pertenecen al S&P/BMV Total México ESG Índex de la Bolsa Mexicana de Valores, con el objetivo de aplicar el cálculo de Q de Tobin que fue propuesta por Tobin (1969), la cual consiste en determinar si la acción de la empresas están subvaluadas, sobrevaluadas o son valoradas correctamente y por otro lado el cálculo de Z score de Altman que fue propuesta por Altman (1968), el cual consiste en pronosticar la quiebra en las empresas, estos cálculos se utilizan para observar si las empresas que pertenecen a este índice tienen: salud financiera, si el valor de la acción de estas entidades está sobrevalorado o infravalorado y las probabilidades de quebrar que tengan estas mismas firmas. Se concluye que a raíz del COVID-19 los Resultados Financieros del primer trimestre de 2020 se vieron afectados y por tanto las empresas están en riesgo de quiebra y otras por su posicionamiento y expansión no se vieron afectadas de acuerdo con los parámetros de los modelos mencionados.
