MODERN PROBLEMS OF АLPORT SYNDROME DIAGNOSIS
Authors: Bratnova Olena
Published: November 2020

Introduction. In the practice of adult nephrologists there are cases of rare genetically caused kidney damage, in particular, Alport syndrome. This is due to the availability and improvement of instrumental diagnostic methods, timely approaches to treatment in pediatric practice, and prolongation of the pre-dialysis period.

Goal. Analysis and synthesis of new data from domestic and foreign sources on the etiology, pathogenesis, clinical manifestations, types of inheritance, differential diagnosis of Alport syndrome in order to improve the success of students, interns and teachers in the study of nephrological subjects.

Material and methods. Review of contemporary and foreign literary sources; techniques – description, analysis, abstracting.

Results. Alport syndrome (AS, synonym: hereditary nephritis) is non-immune genetically determined glomerulopathy caused by a mutation of genes that encode collagen type IV of basement membranes, manifested by hematuria and / or proteinuria, a progressive decreased renal function, combined with pathology of hearing and abnormalities affecting the eyes. Alport syndrome inherited type: X-linked dominant (XLAS): 85%, autosomal recessive (ARAS): 15%, autosomal dominant (ADAS): 1%.

Conclusions. Family history, electron microscopy, immunochemical analysis of type IV collagen expression are informative for verifying the diagnosis of Alport syndrome. Due to the rarity of this disease, in addition, the fact that patients often refuse kidney biopsy, it is necessary to cooperate more closely with genetic laboratories, to take measures to improve the availability of molecular analysis of mutations of collagen IV genes. In addition, it is a fact that sometimes the family history of the disease is ambiguous, unavailable for genetic analysis, and patients refuse to have a kidney biopsy. It is a motive to encourage doctors to improve their educational work with patients about safety of this analysis and its value.

Мета. Вивчити особливості біохімічних показників функції нирок в перебігу плазмоклітинної мієломи у пацієнтів, постраждалих внаслідок аварії на ЧАЕС.Матеріали і методи. Проаналізовано особливості перебігу захворювання у 64пацієнтів з плазмоклітинною мієломою (ПКМ), які знаходились на обстеженні та лікуванні у відділенні радіаційної онкогематології ННЦРМ протягом 2010-2017 рр. Оцінено основні клініко-лабораторні характеристики ПКМ (рівень ЛДГ, β2-мікроглобуліну, альбуміну, кальцію сироватки крові, сечовини, креатиніну та рівня гемоглобіну) з урахуванням радіаційного анамнезу (учасники ліквідації наслідків аварії на ЧАЕС, евакуйовані із зон безумовного відселення, жителі контамінованих територій та група порівняння) і стадії ПКМ за класифікацією Durie-Salmon et al. (1975) та ISS (1985).Результати. Встановлено, що у хворих на ПКМ з обтяженим радіаційним анамнезом порівняно з неопроміненими пацієнтами вірогідно зростав рівень β2-мікро-глобуліну (р=0,02) та кальцію (р=0,04). Підтверджено, що найбільш інформативними характеристиками пацієнтів з ПКМ є рівень сечовини (F = 3,58; р =0,05) та альбуміну сироватки крові (F = 4,00; р = 0,05). Підтверджено суттєвий взаємозв’язок основних показників функції нирок у обстежених, з розвитком анемії та рівнем кальцію, що залежить від ступеню остеолітичного ураження кісткової тканини.Висновки. Виявлені відмінності щодо біохімічних та клініко-гематологічних показників пацієнтів з ПКМ, постраждалих внаслідок аварії на ЧАЕС, і осіб без ускладненого радіаційного анамнезу можуть скласти підґрунтя для прогнозування ефективності перебігу захворювання і потребують подальших досліджень в даному напрямку.

Published: November 2020

Introduction: The transition period in the first year of nursing career is a difficult time for new nurses to adapt. The transition process for a new nurse is known as the Duchscher's transition shock model. Almost all hospitals worldwide have experienced difficulties with regards to the ability of new nurses to adapt to profession. The Preceptorship is a program designed to help new nurses adapt during the transition. This study aims primarily at exploring the impacts of the program to the turnover intention of fresh graduate nurses working in hospital.

Methods: For this major purpose, a qualitative research with particular reference to phenomenology design was applied. Accordingly, this research applied in-depth interviews with active participation of 13 key informants. The informants are fresh graduate nurses employed in two private hospitals in Jakarta.

Results: The results of thematic and cross-case analysis with N Vivo v.12 indicate four themes: preceptorship process, experiences in transition, problem arising during transition period and preceptorship program in helping nurse.

Conclusion: It is found that nurses aged 22 years old and 7 months of working experience are the most likely to resign. The experience of new nurses undergoing to transition period affects 48% of their desire to leave work. This study recommends conducting further research on what kind of work environment is ideal for facilitating adaptation for new nurses.
The Influencing Factors of Dropout and Persistence of Central European Hungarian Minorities in Higher Educational Institutions
Authors: Sütő Zsuzsanna
Published: November 2020

The statistics show that minority Hungarians’ education and participation in higher education, lags far behind the majority of society in Central Europe. Furthermore, we also know that the smaller the community, the more educated they are.  The explanation for this could be, those who are less educated are more prone to assimilate. As a result, the existential question from these minority groups comes down to the growth of their level of education, a condition of which is university students’ acquisition of diplomas. Those factors deserve more scrutiny, in their identification, that increase the chances of getting a diploma. The goal of our study is (1) to identify the students who are persistent and at risk of dropping out, (2) to define the risk factors, and (3) at the same time to uncover the protective/ supporting factors as well. The theoretical background for our research was constituted by the institutional integrational model. The database used for this study contains data collected during a survey of Hungarian students from four different countries in Central Europe (IESA 2015, N= 2017). We found from our research that though the effect of intergenerational connections among students at Central European minority schools proved significant, the effect of place of residence, of settlement type, and of relationships within the family was even stronger.
The Development of the Number of Pupils in Secondary Institutions in Light of Political and School Structure Changes
Authors: Józsa Gabriella
Published: November 2020

There are a number of factors around the world that influence the evolution of school structure such as historical, cultural tradition, nature of the economy, demographics, etc. After-primary school further education is a highlight of the Hungarian school system, as it also defines the entire school career and future of the pupils. The choice between the three types of training, the secondary school, vocational academic school and standard vocational school, is backed by different strategies spanning the entire school career of the students, the educational qualifications being the goal. While choosing high school leads to a degree, the choice of vocational school is one of the fastest and easiest ways of the acquisition of qualifications. However, vocational secondary school also offers a chance to study in higher education (Hermann, 2005) In our study, we look at the evolution of secondary school types in light of policy changes from the 1940s to the present day.
PARENTAL AGE AT CONCEPTION AND RISK OF MALIGNANCIES IN CHILDREN
Authors: Vorobtsova I. , Kanaeva M. , Semenov A. , Dobrogorskaya M.
Published: November 2020

There are considered results of studies on the association between parental age at conception and risk of various childhood and adult-onset cancers in progeny. In spite of inconsistency of data available it is possible to affirm that advanced parental age is a risk factor of cancer in progeny as well as of other adverse health effects. Paternal age seems to be more significant then maternal age due to particularity of gametogenesis in men lasted during whole life (as opposed to women). In a result sperm accumulates much more potential carcenogenic injuries (mutations, epigenetic alterations, particularity of telomeres) transmitted to progeny. The standard designs of studies are described (case-control, population cohort) as well as sources of personal information (Cancer Registers, Registers of Births, interview), parameters of assessment of parental age effect (mean age of parents in case and control groups, odds ratio - OR, relative risk - RR). The causes of discrepancy of results are discussed. Some unusual results are described (association between parental age and hematological cancer, in adult offspring limited to participants without siblings in childhood, protective effect of older ages of parents for some kinds of malignancies in children) which need further investigations.

Published: November 2020

The review considered the issues of epithelial-mesenchymal transition (EMT) and its role in inflammation, fibrosis, tumor growth. There were analyzed mechanisms and classification of EMT. A comparison of different forms of EMTs was performed. The important role of EMT in the formation of metastasis-initiating cells was noted. There were presented data on the role of fibroblasts in fibrosis of the lung, carcinogenesis. Stimulators and inhibitors of EMTs were summarized. There were considered intracellular paths that were associated with the development of the EMT under the influence of transforming growth factor ß1 (TGF - ß1). It also induced the development of local hypothyroidism, for easy expression of oncofetal genes, which was especially important in tumor growth. Therapy EMT was associated with blocking the actions of TGF - ß1 and was an important area in anticancer therapy.
A new Cenozoic record of spinilomatine aporrhaids (Stromboidea, Caenogastropoda) in the early Paleocene of Faxe, Denmark
Authors: Schnetler Kai Ingemann , Milàn Jesper
Published: November 2020

A new find is identified as a representative of the subfamily Spinilomatinae, viz. Spiniloma? faxensis sp. nov. The specimen was found as an impression in coral limestone of the early Paleocene (middle Danian) Faxe Formation in the Faxe quarry in Denmark. The genus Spiniloma was until now known exclusively from the Mesozoic of Europe. The new find extends the stratigraphic range of the genus into the early Paleocene. Furthermore, the gastropod fauna of the Faxe Formation is dominated by gastropods with a preference for hard substrates, while soft- substrate genera like Spiniloma are extremely rare.
A new myriacanthid holocephalian from the Early Jurassic of Denmark.
Authors: Duffin Christopher J. , Milàn Jesper
Published: November 2020

A new myriacanthid holocephalian is described from the Hasle Formation (probably the Uptonia jamesoni subzone to the Acanthopleuroceras valdani subzone, Early Pliensbachian, Early Jurassic) of Bornholm, Denmark, on the basis of isolated upper posterior (palatine) and lower posterior (mandibular) tooth plates. Oblidens bornholmensis gen. et sp. nov. differs from all other myriacanthids for which the same dental elements are known, in the distribution of the hypermineralised tissue covering the occlusal surfaces of the tooth plates, and the arrangement of the ridges transecting the tooth plate surface and so varying their surface relief. Oblidens is the first myriacanthid holocephalian to be recorded both from the Pliensbachian and from Denmark. The presence of a further, undetermined myriacanthid tooth plate is noted from the same locality.
A crocodilian coprolite from the lower Oligocene Viborg Formation of Sofienlund Lergrav, Denmark
Authors: Milàn Jesper , Rasmussen Erik Skovbjerg , Dybkjær Karen
Published: November 2020

A large, well-preserved vertebrate coprolite found in the clay pit Sofienlund Lergrav, Jylland, is identified as crocodilian due to its size and morphology. The coprolite consists of several concentric layers wrapped around a more homogeneous core. Weak constriction marks are present on the surface. Dinoflagellate cyst contents of the coprolite indicate a mid-Lutetian to earliest Rupelian (middle Eocene to earliest Oligocene) age, which at Sofienlund Lergrav places it within the lower Oligocene Viborg Formation. The coprolite can thus be dated as approximately 33–34 Ma old. The Viborg Formation in Denmark represents a period with deposition of hemipelagic marine clay and formation of glaucony.
The nearest shoreline was located c. 200 km north of the location of the present day Sofienlund Lergrav, and the climate was humid, warm-temperate to sub-tropical. The presence of a crocodilian coprolite is an important addition to the sparse Oligocene vertebrate fauna of Denmark, which previously only consisted of sharks and cetaceans.
El análisis de redes sociales, un puente teórico-metodológico entre la etnografía y la arqueología
Authors: Teves Laura , Cueto Jorge Julián
Published: November 2020

El objetivo de este trabajo es presentar los aportes del análisis de redes sociales a la investigación en los dominios de la etnografía y la arqueología. Para esto, exponemos los supuestos básicos de la investigación relacional enfatizando en la generación de modelos de validez interdisciplinar, así como los resultados de un estudio etnográfico sobre la actividad textil en los Valles Calchaquíes salteños. En la descripción de la actividad textil utilizamos la noción de secuencia operativa, en la que intervienen actores, materias primas, tecnologías, procesos y comunidades de práctica. El estudio se fundamentó en tres hipótesis: 1) la actividad textil coexiste con otras actividades de subsistencia, que se desarrollan entre diversos actores y unidades domésticas locales; 2) las relaciones personales en la actividad cotidiana se imbrican a diferentes niveles – micro, meso y macro- de la estructura y la organización social; y 3) la obtención de recursos y las actividades de las unidades domésticas se corresponden espacialmente con ambientes ecológicos –“del alto” y “del bajo”- que son complementarios regionalmente. Finalmente, sostenemos que la teoría y la metodología del análisis de redes sociales constituyen herramientas para la investigación etnográfica, en tanto estimulan la generación de hipótesis y propician acomodamientos en los diseños de investigación tendientes a la modelización estructural de problemas sociales actuales y del pasado. De esta manera, se abre un campo heurísticamente fructífero que tiende puentes entre la investigación etnográfica y arqueológica.
Aportes de la teledetección y SIG al estudio arqueológico de la cría de animales en el valle Calchaquí Norte (dpto. de Cachi, Salta, Argentina)
Authors: Jakel Andrés , Minichelli Bianca
Published: November 2020

Este trabajo apunta a analizar diversos aspectos materiales que contribuyen a dar forma al paisaje arqueológico en el Valle Calchaquí Norte (Dto. de Cachi, Salta, Argentina). Este objetivo se enmarca en una investigación etnográfica y arqueológica en curso, en la cual se aborda el pastoreo en los valles, sus estrategias de movilidad asociadas, como así también otros aspectos espaciales y sus vínculos con la actividad agrícola. A través de la teledetección y la aplicación de los Sistemas de Información Geográfica (SIG), el presente artículo busca explorar y analizar la presencia, la distribución y las relaciones espaciales de estructuras que estarían presumiblemente asociadas a las actividades de cría/manejo de animales, así como aquellas asociadas a la actividad agrícola en el área. Se asume una perspectiva basada en la propuesta teórica de Ingold, para abordar la cuestión espacial a través de la noción de taskscape, y se discute la adecuación del concepto de agro-pastoralismo para el abordaje de los fenómenos observados en la región junto a sus correlatos espaciales y materiales. Por último, se plantean vías de indagación futuras acerca de su temporalidad.

Published: November 2020

We survey some recent developments in the study of collapsing Riemannian manifolds with Ricci curvature bounded below, especially the locally bounded Ricci covering geometry and the Ricci flow smoothing techniques. We then prove that if a Calabi-Yau manifold is sufficiently volume collapsed with bounded diameter and sectional curvature, then it admits a Ricci-flat Kähler metrictogether with a compatible pure nilpotent Killing structure: this is related to an open question of Cheeger, Fukaya and Gromov.
Compressible Turbulence in the Interstellar Medium: New Insights from a High-resolution Supersonic Turbulence Simulation
Authors: Ferrand R. , Galtier S. , Sahraoui F. , Federrath C.
Published: November 2020

The role of supersonic turbulence in structuring the interstellar medium (ISM) remains an unsettled question. Here, this problem is investigated using a new exact law of compressible isothermal hydrodynamic turbulence, which involves two-point correlations in physical space. The new law is shown to have a compact expression that contains a single flux term reminiscent of the incompressible case and a source term with a simple expression whose sign is given by the divergence of the velocity. The law is then used to investigate the properties of such a turbulence at integral Mach number 4 produced by a massive numerical simulation with a grid resolution of

points. The flux (resp. source) term was found to have positive (resp. negative) contribution to the total energy cascade rate, which is interpreted as a direct cascade amplified by compression, while their sum is constant in the inertial range. Using a local (in space) analysis it is shown that the source is mainly driven by filamentary structures in which the flux is negligible. Taking positive defined correlations reveals the existence of different turbulent regimes separated by the sonic scale, which determines the scale over which the nonnegligible source modifies the scaling of the flux. Our study provides new insight into the dynamics and structures of supersonic interstellar turbulence.
Chains of Planets in Mean Motion Resonances Arising from Oligarchic Growth
Authors: Morrison Sarah J. , Dawson Rebekah I. , MacDonald Mariah
Published: November 2020

Exoplanet systems with multiple planets in mean motion resonances have often been hailed as a signpost of disk-driven migration. Resonant chains like Kepler-223 and Kepler-80 consist of a trio of planets with the three-body resonant angle librating and/or with a two-body resonant angle librating for each pair. Here we investigate whether close-in super-Earths and mini-Neptunes forming in situ can lock into resonant chains due to dissipation from a depleted gas disk. We simulate the giant impact phase of planet formation, including eccentricity damping from a gaseous disk, followed by subsequent dynamical evolution over tens of millions of years. In a fraction of simulated systems, we find that planets naturally lock into resonant chains. These planets achieve a chain of near-integer period ratios during the gas-disk stage, experience eccentricity damping that captures them into resonance, stay in resonance as the gas disk dissipates, and avoid subsequent giant impacts, eccentricity excitation, and chaotic diffusion that would dislodge the planets from resonance. Disk conditions that enable planets to complete their formation during the gas-disk stage enable those planets to achieve tight period ratios ≤2 and, if they happen to be near-integer period ratios, lock into resonance. Using the weighting of different disk conditions deduced by MacDonald et al. and forward modeling Kepler selection effects, we find that our simulations of in situ formation via oligarchic growth lead to a rate of observable trios with integer period ratios and librating resonant angles comparable to observed Kepler systems.
On the Temperature Profiles and Emission Spectra of Mini-Neptune Atmospheres
Authors: Piette Anjali A. A. , Madhusudhan Nikku
Published: November 2020

Atmospheric observations of mini-Neptunes orbiting M dwarfs are beginning to provide constraints on their chemical and thermal properties, while also providing clues about their interiors and potential surfaces. With their relatively large scale heights and large planet–star contrasts, mini-Neptunes are currently ideal targets toward the goal of characterizing temperate low-mass exoplanets. Understanding the thermal structures and spectral appearances of mini-Neptunes is important to understand various aspects of their atmospheres, including radiative/convective energy transport, boundary conditions for the interior, and their potential habitability. In the present study, we explore these aspects of mini-Neptunes using self-consistent models of their atmospheres. We begin by exploring the effects of irradiation, internal flux, metallicity, clouds, and hazes on the atmospheric temperature profiles and thermal emission spectra of temperate mini-Neptunes. In particular, we investigate the impact of these properties on the radiative–convective boundary and the thermodynamic conditions in the lower atmosphere, which serves as the interface with the interior and/or a potential surface. Building on recent suggestions of habitability of the mini-Neptune K2-18 b, we find a range of physically motivated atmospheric conditions that allow for liquid water under the H2-rich atmospheres of such planets. We find that observations of thermal emission with JWST/MIRI spectrophotometry can place useful constraints on the habitability of temperate mini-Neptunes such as K2-18 b and provide more detailed constraints on the chemical and thermal properties of warmer planets such as GJ 3470 b. Our results underpin the potential of temperate mini-Neptunes such as K2-18 b as promising candidates in the search for habitable exoplanets.

We utilize deep Chandra X-ray Observatory imaging and spectra of M82, the prototype of a starbursting galaxy with a multiphase wind, to map the hot plasma properties along the minor axis of the galaxy. We extract spectra from 11 regions up to ±2.5 kpc from the starbursting midplane and model the data as a multitemperature, optically thin thermal plasma with contributions from a nonthermal (power-law) component and from charge exchange (CX). We examine the gradients in best-fit parameters, including the intrinsic column density, plasma temperature, metal abundances, and number density of the hot gas as a function of distance from the M82 nucleus. We find that the temperatures and number densities of the warm–hot and hot plasma peak at the starbursting ridge and decrease along the minor axis. The temperature and density profiles are inconsistent with spherical adiabatic expansion of a super-heated wind and suggest mass loading and mixing of the hot phase with colder material. Nonthermal emission is detected in all of the regions considered, and CX comprises 8%–25% of the total absorption-corrected, broadband (0.5–7 keV) X-ray flux. We show that the abundances of O, Ne, Mg, and Fe are roughly constant across the regions considered, while Si and S peak within 500 pc of the central starburst. These findings support a direct connection between the M82 superwind and the warm–hot, metal-rich circumgalactic medium (CGM).

The four-spined pygmy devil (Arulenus validispinus Stål, 1877) is an endemic species to the Philippines. It was described more than 140 years ago from a single female specimen. Since its description, only a single new record was known, reported by Skejo from the Lanao region in 2017 and based on a specimen from eBay. Here, we record the species from the Bukidnon Mountains. We present measurements of a male and a female we collected, with the description of the species morphology and habitat. This species differs from its congeneric Mia’s pygmy devil (A. miae Skejo & Caballero, 2016) by the sharp dorsal and lateral spines.
Application of Sensor Networks for Measuring Insulin Levels
Authors: Pandurski Martin Nikolov , Tsvetanov Filip Atanasov
Published: November 2020

All WBANs are low-speed networks consisting of intelligent sensors and low-power actuators that can be placed on the body or implanted in humans. With the help of these networks, timely on-line data on unusual conditions of the human body can be provided, which leads to significant improvements in the quality of life. The implementation of these networks will save lives, reduce healthcare costs, and eliminate the need for costly monitoring of patients in the hospital. The paper analyzes the possibilities of the Internet of Things technology, communication standards, cloud technologies, and hardware components for developing a system for monitoring insulin levels in diabetic patients. A model and algorithm for design, construction, and management of a sensor network for monitoring insulin levels with simulation software based on the Internet of Things technology proposed. A system for monitoring insulin levels through a cloud structure has designed, which sends a message to a specialized health centre or the attending physician about the condition of diabetic patients. Simulation studies performed, and the operability of the system examined. The results give reason to believe that the considered model and the simulation project of a system for monitoring insulin levels in patients with diabetes is successful, gives realistic and reliable results for early diagnosis and prevention of various complications and can be implemented in practice.

Published: November 2020

O ensino de Inglês para Fins Acadêmicos (IFA) foi intensificado devido à internacionalização das universidades brasileiras, ao papel do inglês como língua de divulgação científica e à oferta de cursos de inglês para a comunidade universitária pelo Programa Idiomas sem Fronteiras (IsF). Com isso, tornou-se relevante investigar a formação de professores de inglês para esse fim. O objetivo deste artigo é descrever e analisar os desafios enfrentados pelos professores-bolsistas do IsF ao preparar e conduzir aulas com foco em inglês acadêmico. Este trabalho utiliza como metodologia a pesquisa qualitativa interpretativa (Mason, 2002; Erickson, 1990) para a análise de 11 entrevistas semiestruturadas com professores-bolsistas do IsF de uma universidade pública brasileira. Os resultados sugerem que os principais desafios enfrentados são tornar as aulas de IFA mais dinâmicas, criar e adaptar materiais didáticos e atender às necessidades de alunos de diversas áreas do conhecimento.Palavras-chave: Inglês para Fins Acadêmicos; Formação docente; Idiomas sem Fronteiras.
O papel da reflexividade no desenvolvimento profissional docente de professores de Língua Inglesa em formação inicial
Authors: Francescon Paula Kracker , Cristovão Vera Lúcia Lopes
Published: November 2020

O presente artigo tem como objetivo investigar se e como atividades reflexivas promovem indícios de desenvolvimento profissional docente. Para alcançá-lo, embasamos nosso estudo nos conceitos de desenvolvimento e reflexividade do Interacionismo Sociodiscursivo (ISD) e na concepção de Sequência de Formação (SF) como dispositivo didático-formativo implementado para condução da investigação. Assim, os dados analisados provêm de uma parte da SF que engloba as atividades reflexivas, conduzidas por meio de sessões de autoconfrontação (AC) com os alunos-professores (AP) participantes. Na análise, identificamos as dimensões de reflexividade mobilizadas pelos participantes e como a reflexividade sobre os tópicos abordados pelos AP promovem indícios de desenvolvimento profissional. Com base nos resultados, defendemos a inclusão de atividades de reflexividade em SF, como momento oportuno para conscientização e debate de práticas, e (re)construção de entendimentos, etapas necessárias para o processo de desenvolvimento.Palavras-chave: desenvolvimento docente; reflexividade; Sequência de Formação.

Perspectiva meta: integração e colocação em foco das unidades linguísticas
Authors: Barbeiro Luís
Published: November 2020

A Leitura Detalhada (LD) constitui uma atividade do programa Ler para Aprender, que coloca em foco unidades linguísticas selecionadas, solicitando a sua identificação e aprofundando o conhecimento sobre elas e as relações que estabelecem. O objetivo do presente estudo é caracterizar a atividade em relação à ativação e ao aprofundamento do conhecimento metalinguístico. O enquadramento teórico é constituído pela perspectiva que atribui à consciência metalinguística um papel relevante para o desenvolvimento linguístico. A consciência das escolhas e do seu alcance semiótico pode emergir na interação discursiva que ocorre durante a LD. Nessa interação, as unidades linguísticas podem ser referidas e caracterizadas quanto às suas propriedades sistémicas e funcionais, mobilizando o conhecimento metalinguístico. Metodologicamente, registrou-se a interação entre professor e alunos (5.º ano de escolaridade) e efetuou-se a sua análise quanto à referência metalinguística, aos termos utilizados e às propriedades explicitadas pelos professores e alunos. Os resultados mostram que a LD apresenta um grau elevado de atividade metalinguística, a qual pode ser orientada para a aprendizagem do conhecimento metalinguístico, para além das potencialidades em relação à consciencialização dos reflexos da escolha de recursos linguísticos específicos para a construção dosignificado, habitualmente associadas à LD.Palavras-chave: Conhecimento metalinguístico; Leitura Detalhada; Ler para Aprender.
Educação e a pesquisa etnográfica crítica: a qualidade das relações entre os sujeitos
Authors: Damasceno de Moraes Júlia Pereira , Locks Geraldo Augusto
Published: November 2020

Este artigo resulta de uma pesquisa qualitativa-etnográfica-crítica realizada em um Programa de Mestrado em Educação de uma universidade do interior de Santa Catarina, em 2018. Os sujeitos de pesquisa são associados a uma Cooperativa de Catadores de Materiais Reciclados. No concernente à metodologia adotada para a escrita desse artigo, evidenciou-se que a abordagem qualitativa, em que a releitura do texto dissertativo, de referências bibliográficas amplamente usadas no processo da pesquisa de campo e a revisão do diário de campo seriam um caminho profícuo.  Como objetivo geral, compreender, nas relações de quem pesquisa e de quem é pesquisado, questões relacionadas à sociedade de consumo e do descartável, à organização de sujeitos em processo de empoderamento e à relevância da etnografia crítica fora do ambiente escolar. Como resultados, destacam-se a importância do processo de formação do sujeito pesquisador e a necessidade de aprofundar os estudos sobre a subjetividade das relações sociais enquanto força motriz de práticas que contribuam para a compreensão de que a pesquisa com pessoas implica em pesquisa com sujeitos, e não com objetos de estudo.

Authors: Farias Isabel Maria Sabino de , Saraiva Alexsandro Macêdo
Published: November 2020

Na história do Brasil, o Ensino Religioso protagonizou as disputas político-ideológicas entre Estado e Igreja acerca do princípio da laicidade que permearam a maioria das Cartas Magnas do país. Nesse sentido, este estudo, que tem como viés o exame bibliográfico, objetivou apresentar o Estado da Questão dos trabalhos acadêmicos produzidos no Brasil (artigos científicos, dissertações e teses) sobre o Ensino Religioso na escola pública brasileira. Tendo em vista a compreensão das temáticas abordadas, buscamos identificar onde, como e quando estes trabalhos foram produzidos. Os resultados indicam um crescente interesse sobre o tema pelos pesquisadores, todavia em posicionamentos divergentes no que diz respeito à permanência ou não desta disciplina no currículo escolar, ensejando no espaço acadêmico um campo ainda bastante tenso de visões que demarcam as disputas de território desta disciplina no currículo da educação brasileira.
