Liquidity and Profitability Management in an Emerging Market: Evidence from Vietnamese Fertilizer Companies
Authors: Nguyen Hien Thi Thu , Thi Vu Phuong , Nguyen Van Cong
Published: June 2022

This study aims to investigate and measure the impact of liquidity on profitability management in an emerging market. The panel data used for the study is collected from the audited financial statements of companies trading in the fertilizer industry traded on the Vietnamese stock market for the period from 2010 to 2019. The study compares the regression results between Pooled OLS, Fix Effect Model and Random Effect Model estimates with the Hausman test and Lagrange multiplier test to select a suitable regression model. Research results reveal that Quick Ratio and Days Inventory Outstanding factors positively affect Return On Equity but not Return On Assets; factors Days Sales Outstanding and Days Payable Outstanding have a negative impact on Return On Assets but not on Return On Equity. Particularly, the Current Ratio factor has a positive effect on Return On Assets but has a negative effect on Return On Equity. The research results can be applied to many different economic sectors as well as help policymakers and regulators in examining and regulating the relationship between liquidity and business profitability

Published: June 2022

Background:

Minimally invasive approaches to intra/extraforaminal lumbar disc herniations offer the benefit of less bone removal and reduced nerve root manipulation at the L5-S1 level. Moreover, the potential to better preserve stability.

Methods:

Here, we summarized the efficacy of the contralateral approach to intraforaminal/extraforaminal lumbar disc herniations particularly focusing on the L5-S1 level. Variables studied included the level of these disc herniations, their locations within the foramina, and the anatomy of the facet joints.

Results:

A major “pro” for the contralateral interlaminar procedure at the L5-S1 level is that it does not require facet joint removal, or with a spondylotic facet, <30% joint excision, to directly visualize the intraforaminal/ extraforaminal nerve root. It, therefore, reduces the risk of creating iatrogenic instability, while offering a higher certitude of adequate nerve root visualization, decompression, and safer disc removal.

Conclusion:

The contralateral interlaminar approach is more suitable for all types of intra/extraforaminal disc herniations at the L5/S1 level. The most specific benefit of this approach is its avoidance of disruption/significant removal (i.e., <30%) of the facet joint to adequately expose the foraminal L5 nerve root, and more safely remove the intra/extraforaminal disc herniation.

Published: June 2022

Purpose. To study the epidemiological features of cataracts and the organization of medical care for people with this pathology. Material and methods. In the population cross-sectional study Ural Eye and Medical Study on the basis of the Ufa Research Institute of Eye Diseases, 5899 people aged 40 years and older took part, among them men – 43.7% (2580 people), women – 56.3% (3319 people). Statistical data analysis was performed using the IBM SPSS Statistic software package. Results. According to the results of the study, the prevalence of cataract in people older than 40 years was 42.8% (95% CI: 41.4–44.2%), the prevalence of cataract surgery was 6.1% (95% CI: 4.0–9.3%). The coverage of surgical treatment of patients with cataracts among the study population was 39.8%, the rate of its effectiveness was 32.1%. The main reason that reduces patients’ adherence to timely treatment is the lack of interest of the patient himself and insufficient awareness of the complications and methods of modern cataract treatment. Conclusion. The introduction of medical and organizational measures contributed to an increase in the overall coverage of surgical treatment of people with cataracts by 25.6% (from 39.8 to 65.4%), the rate of effective coverage of surgical treatment of patients with cataracts – from 32.1 to 57, 7% and the target for maximum visual acuity fr om 80.6 to 88.2%.

Published: June 2022

Purpose.To highlight the data of scientific papers on the development of herpes eye diseases in patients with COVID-19 and after vaccination against this infection. Material and methods. To complete the review, we searched for literature sources in the PubMed and Scopus reference databases for the period from 2019 to 2022 using the keywords «herpesvirus eye infection covid-19», «herpes virus eye infection, vaccination for COVID-19». In total, 30 articles were selected that relate to the topic of the review. Discussion. According to some researchers, SARS-CoV-2 infection may be a risk factor for the development and reactivation of herpes viruses, which is much more common in invasively ventilated patients with COVID-19. Indirectly, this is evidenced by the growth in the number of patients with ophthalmic herpes during the COVID-19 pandemic around the world. The literature also discusses cases of development or recurrence of ophthalmic herpes after the use of various types of vaccines. While there are various assumptions of their occurrence, one of them seems to be related to the stimulation of the immune system after vaccination and the activation of a strong T-cell response, which allows viruses to emerge from the latent phase, which requires scientific research. Conclusion. The literature review suggests that, according to the studies published to date, COVID-19 can be a potential activator of HSV-1 infection, and, accordingly, become a risk factor for the development of ophthalmic herpes. Therefore, patients with COVID-19 are advised to prescribe antiherpetic drugs as additional therapy. Key words: covid-19, herpes eye infection, COVID-19, vaccination

This review presents the results of a study of patients with diabetic retinopathy (DR) suffering from myopia. It is shown that in patients with different variants of the length of the anterior-posterior part of the eye, the contraction, development and progression of DR occurs in different ways. Thus a number of authors note that DR generally does not develop in patients with high myopia. Some attribute this to impairment of circulation in the retinal stretching of the myopic eye, others to the concentration of vascular endothelial growth factor (VEGF), which is significantly lower in eyes with a longer axis or greater myopic refraction, and others to a focal continuity disorder in the pigment epithelium layer, in which metabolic products are removed through the choroid and sclera, as a result of which local acidosis, venous statis don’t develop, and the barrier function of the vascular endothelium is not disturbed. Key words: diabetic retinopathy, myopia, anterior and posterior segment, vascular endothelial growth factor, emmetropia, hypermetropia, diabetes mellitus

Purpose. To share the first experience of using new generation injectors to introduce pre-prepared DMEK and DSAEK grafts through minimal incisions by injection. Methods. The results of operations in 2 groups of patients were analyzed. In the first group (2 patients), for the DMEK procedure, the Descemet's membrane with endothelium was isolated by the new non-contact method “BLISTER”. Prepared DMEK grafts were preloaded into a new injector – a modified Jones Tube 2.0 mm (LEITR, USA), placed into Optisol-GS medium and sent from the USA to Tashkent for transplantation. To carry out the DSAEK procedure in the second group of 6 patients, grafts (n = 6) with a thickness of 54 to 68 microns were preliminarily prepared using the new HPAC method, preloaded into a new injector – a modified Jones Tube 3.0 mm (LEITR, USA), placed into Optisol-GS medium and sent from the US Eye Bank to Tashkent for operations. The postoperative follow-up period ranged from 8 to 12 months. Results. There were no intraoperative and postoperative complications in the DMEK group. In the DSAEK group, transient hypertension was observed in the postoperative period in 2 patients and one patient required additional air injection into the anterior chamber. Complete epithelialization in both groups was observed within 6–7 days. Pachymetry analysis of the regression of edema of the stroma of the recipient and donor tissue indicated a faster positive trend in the first group and ranged from 4 weeks to 2 months, in contrast to the 2nd group, where this indicator ranged from 2 to 4 months. Uncorrected visual acuity reached maximum in the 1st group within 3 months and averaged 0.8. Uncorrected visual acuity in the 2nd group was restored to maximum values within 5 months and amounted 0.32. Conclusions. A new generation of injectors designed for the introduction of DSAEK and DMEK grafts prepared in advance in the eye bank allows minimizing surgical incision, greatly simplifying the work of the surgeon and obtaining high functional results. Key words: сorneal transplantation; deep posterior lamellar keratoplasty; bullous keratopathy; DSAEK; DMEK; injector.

Baсkground. Recently, additional microtraumatization of neuroretinal tissue has been proven during removal of the internal limiting membrane (ILM) due to its close connection with the inner layers of the retina and with Muller cells. These factors may influence functional results after surgery for closure of macular hole. Purpose. To propose a new technique of surgery for macular hole, which is based on the preservation of ILM and to assess the dynamics of the functional parameters of the retina. Methods. The results of OCT of 60 patients (60 eyes) with the diagnosis of macular hole were analyzed. Group 1 (30 eyes) – patients who underwent surgical treatment with inverted flap. Group 2 (30 eyes) – patients who were operated using the original method with preservation of ILM in the central zone. All patients underwent standard ophthalmological examination before and after surgery, including visometry, biomicroscopy, ophthalmoscopy, and OCT. Results. Preoperative functional parameters of the retina were comparable in both groups of patients. The study identified 3 types of macular hole closure. When studying morphological changes in macular hole repair by the “pseudocyst” type in patients of both groups, it showed a more pronounced resistance of neuroretinal tissue in patients of group 1. In the 2nd group, more pronounced dynamics of reducing the morphological parameters of the hyporeflective defect was revealed throughout the entire observation period. When the macular hole is completely closed, there is a higher rate of regression of neuroepithelial tissue edema in group 2 patients. Non-closure of the macular hole was observed only in group 1 patients, and in this type of repair, there was a deterioration in morphological parameters. Conclusion. Based on this study, we can conclude that using this technique the ILM is preserved, which reduces the risk of intraoperative damage to the retinal layers. Key words: macular hole; peeling; microperimetry.

Purpose. To carry out a comparative analysis of the results of strabismological examination of patients with primary inferior oblique muscle overaction using the generally accepted and proposed methods. Methods. The research included 123 patients with bilateral symmetric primary inferior oblique muscle overaction. The proposed method consisted in measuring hypertropia magnitude of the adducted eye with the maximum fixing movement of the abducted eye gaze and in measuring heterotropia magnitude with the maximum gaze movement upwards and downwards. Results. As a result of diagnostics according to the generally accepted and proposed method, a statistically significant increase in hypertropia and V-syndrome (р < 0.05) was revealed. A more pronounced degree of hypertropia was detected in 110 patients (89.43 %), more pronounced manifestations of the V-syndrome in 117 patients (95.12 %). In 83 patients (67.48 %), the tactics of surgical treatment was optimized. Conclusions. The average underdiagnosis of hypertropia and V-pattern during the examination according to the generally accepted method is 3.98±2.39° and 3.72±2°, respectively.

Aim. To determinete the dependence of value of the postoperative vault height of the phakic intraocular lens on the calculated parameters. Evaluation of the effect of postoperative vault height on autorefractometry parameters. Methods. Preoperative diagnostic data were analyzed: anterior chamber depth, white-to-white distance (WtW), implanted phakic intraocular lens size, and postoperative PIOL vault height (VAULT) data in the late postoperative period on the ANTERION multimodal imaging platform (Heidelberg Engineering, Germany) after 1.5–2 years, and the value of refraction. The total number of observations was 20 eyes (10 patients). Results. The mean value of VAULT among the observed patients was 438±111.7 mkm. The average value of the PIOL size was 12.9±5.3 units. The average depth of the anterior chamber was 3.12±0.2 mm. The performed correlation analysis showed that the VAULT index does not depend on the size of the PIOL, the value of the depth of the anterior chamber of the eye, and the value of WtW. A reliable, strong and direct correlation was established between the PIOL size and the WtW value. Conclusion. The presented analysis showed that the value of VAULT in patients in the late postoperative period does not depend on the values of the variables WtW, the depth of the anterior chamber, and the size of the PIOL. Key words: phakic intraocular lens; phakic IOL vault height; anterior chamber depth; optical coherence tomography.

The state of functioning and development of the state environmental monitoring system and its compliance with current requirements have been analyzed. The troublesome issues of insufficient efficiency of this system due to the interaction of environmental monitoring entities, their tasks and fundamental principles of organization have been studied. The priority directions of the state ecological policy concerning creation of effective information and analytical system of monitoring of natural resources have been offered. The functioning of an effective information and analytical system of environmental monitoring is an integral part of state policy in the field of environmental protection. The key purpose of environmental monitoring is collecting, storing and processing reliable and up-to-date information necessary to develop measures to prevent and reduce the negative consequences of changes in the environment. The importance of introducing an effective environmental monitoring system is of vital importance in the context of reforms of environmental management and protection. All indicators of environmental monitoring should become part of a single national network. It will include information on the state of air, surface, groundwater and marine waters, lands, soils, forests and biodiversity, as well as monitoring waste management, geological processes and the effects of temperature, noise, vibration, and radiation on people and the environment. The environmental monitoring system is an integrated information system that should collect, store and process environmental information for departmental and comprehensive assessment and forecast of the environment, biota and living conditions, making sound recommendations for effective social, economic and environmental decisions at all levels of state executive power, improvement of relevant legislative acts as well as fulfillment of obligations of Ukraine on international agreements, programs, projects and activities.

Purpose: The Covid 19 pandemic has had enormous impacts on healthcare and orthopaedic services globally. The aim of our study was to assess the impact that the covid 19 pandemic has had on the epidemiological pattern of outpatient fractures clinic attendances. Methods: An observational retrospective study was performed looking at epidemiology of fractures seen at our fracture clinics during a three-month period of level 5 restrictions of the covid 19 pandemic and the equivalent period pre pandemic. Data pertaining to demographics, aetiology and fracture types are presented. Results: Patient attendances decreased from 117 in the ‘non-covid era’ to 77 in the ‘covid era’ with a total of 109 and 77 fractures identified respectively. Patients were mostly female with a median age of 55. National lockdown measures impacted the mechanism of injury with expected decreases in sporting injuries. The most common fracture types involved the carpus and hand, foot and ankle and malleoli with the proportion of distal forearm fractures increasing in the covid era. Conclusion: Fracture clinic presentations decreased during the covid era with a higher proportion of fragility fractures. This data may raise awareness regarding the effect of lockdown on an orthopaedic outpatient service for resource allocation for potential future waves.

An unprecedented sandwich complex of the actinides is synthesized from the treatment of [UI2(HMPA)4]I (HMPA = OP(NMe2)3) (2) with 3 equiv. of K[C14H10] to give the neutral, bis(arenide) species U(η6-C14H10)(η4-C14H10)(HMPA)2 (1). Solid-state X-ray, SQUID magnetometry, and XANES analyses are consistent with tetravalent uranium supported by [C14H10]2- ligands. In one case, treatment of 1 with an equiv. of AgOTf led to the isolation of U(η6-C14H10)2(HMPA)(THF) (3), formed from ring migration and haptotropic rearrangement. Complete active space (CASSCF) calculations indicate the U-C bonding to solely consist of π-interactions, presenting a unique electronic structure distinct from classic actinide sandwich compounds.
Chiral perovskite nanoplatelets exhibiting circularly polarized luminescence through ligand optimization

Published: June 2022

Chiral halide perovskite nanocrystals have many applications in next-generation optoelectronic devices due to their interaction with circularly polarized light. Through the careful selection of chiral organic surface ligands, control over the circular dichroism (CD) and circularly polarized luminescence (CPL) of these materials can be achieved. However, while recent developments of CD-active perovskites have seen significant advances, effective CPL remains a challenge. Here, we synthesize colloidal perovskite nanoplatelets exhibiting room temperature CPL with dissymmetry factors up to glum=4.3×10^(-3) and gabs=8.4×10^(-3). Methylammonium lead bromide nanoplatelets are synthesized with a mixture of chiral dimethyl benzyl ammonium ligands and achiral octylammonium ligands, the precise ratio of which is shown to be critical to achieving high g-factors. We investigate the competitive binding of these surface ligands using 1H NMR, and use an equilibrium model to demonstrate the ligand affinity. The magnitude of CPL and CD is quantitatively shown to exhibit a linear correlation, such that glum=0.4×gabs. Lastly, by screening several amines with close structures, we show that subtle differences in ligand structure have significant impact on the resulting CD signal of the nanoplatelets. Our findings provide new insights for the effective design of perovskites exhibiting CPL and can facilitate the development of high-performance devices based on circularly polarized luminescence.
Accurate theoretical evaluation of strain energy of all-carboatomic ring (cyclo[2n]carbon), boron nitride ring, and cyclic polyacetylene
Authors: Lu Tian , Liu Zeyu , Chen Qinxue
Published: June 2022

Cyclocarbon fully consists of sp-hybridized carbon atoms, which shows quite unusual electronic and geometric structures compared to common molecules. In this work, we systematically studied strain energy (SE) of cyclocarbons of different sizes using regression analysis method based on electronic energies evaluated at the very accurate DLPNO-CCSD(T)/cc-pVTZ theoretical level. In addition, ring strain of two systems closely related to cyclocarbon, boron nitride (BN) ring and cyclic polyacetylene (c-PA), is also explored. Very ideal relationships between SE and number of repeat units (n) are built for cyclo[2n]carbon, BnNn, and [2n]c-PA as SE = 555.0•n^-1, 145.1•n^-1 and 629.8•n^-1 kcal•mol^-1, respectively, and the underlying reasons of the difference and similarity in their SEs are discussed from electronic structure perspective. In addition, force constant of harmonic potential of C-C-C angles in cyclocarbon is derived based on SE values, the result is found to be 56.23 kcal•mol^-1•rad^-2. The possibility of constructing homodesmotic reactions to calculate SEs of cyclocarbons is also explored in this work, although this method is far less rigorous than the regression analysis method, its result is qualitatively correct has the advantage of much lower computational cost. In addition, comparison shows that ωB97XD/def2-TZVP is a good inexpensive alternative to the DLPNO-CCSD(T)/cc-pVTZ for evaluating energies used in deriving SE, while the popular and very cheap B3LYP/6-31G(d) level should be used with caution for systems with global electron conjugation such as c-PA.

As a result, a digital economy is being formed as a subsystem of the traditional economy, characterized by the active use of digital technologies and the circulation of specific electronic goods. The monograph is intended for researchers, teachers, graduate students, undergraduates, as well as a wide range of readers interested in topical issues of digitalization of the economy.
Fifty years of journal Kinesiology
Authors: Čolakovac Ivan , Barković Iva
Published: June 2022

The aim of this paper was to present the development of the journal Kinesiology – International Journal of Fundamental and Applied Kinesiology over the five decades of its publication through the analysis of the articles using bibliometric indicators. The sample consisted of 1083 articles published over the period of 50 years, from the 1st volume in 1971 until the 52nd volume in 2020. The analysis of the articles revealed that the most common articles were original scientific papers, while the least represented articles were categorized as conference papers. From 1971 to 1996, most articles were written in the Croatian language, but since 1997, the articles have been written only in the English language. An analysis of the cited references in the last decade of the journal’s publication was made in order to point out the patterns of scientific communication in kinesiology and to determine the recognizability of the published papers at the international level. Since 2006, greater visibility of Kinesiology – International Journal of Fundamental and Applied Kinesiology has been enabled by providing access to full texts of publications through the Portal of Scientific Journals of Croatia – Hrčak, whereas the articles published until the end of 2005 were retrogradely digitized.

Fabulações curriculares
Authors: Coelho Olivia Pires , Canavieira Fabiana Oliveira
Published: June 2022

O potencial inventivo, no pensamento de Gilles Deleuze, reside no entrelaçamento das artes, da ciência e da filosofia para criação de conceitos. Os conceitos são, por sua vez, as ferramentas do filósofo para resolver problemas. Neste artigo, nosso objetivo é operar em singularidades conceituais para discutir concepções de infância a partir do paradigma descolonizador, refutando a gramática pedagógica colonizadora. Para tanto, articulamos elementos das artes, através de experimentações literárias - rizomaticamente - com as ferramentas conceituais da ciência e da filosofia, para pautar a construção de uma tessitura de infância que possa habitar o plano de imanência do infinito. Nesse contexto, questionamos a fabulação de um currículo da infância que abarque seu infinito.
Educación inicial
Authors: Brailovsky Daniel , Labarta Liliana , Descalzo Mónica
Published: June 2022

El curriculum suele ser definido como la expresión de un proyecto pedagógico y didáctico que orienta a docentes e instituciones para dar forma a las prácticas de enseñanza, convirtiendo ciertos intereses públicos en intereses singulares y situados. Se espera, en ese sentido, que el diseño curricular sea desarrollado en las aulas para decidir qué, cómo y para qué enseñar. Pero a la vez, el curriculum es una suerte de declaración de principios, la expresión de una filosofía y una ideología educativas. Y lo que se espera del curriculum (entendido como manifiesto de ideas, enfoques y miradas sobre la enseñanza de la primera infancia, sobre el conocimiento y sobre la sociedad misma) es que sirva a docentes e instituciones como espacio de inspiración, de reflexión sobre los sentidos de la enseñanza, como fuente de vocabulario, como política de discurso y como ámbito de construcción de pertenencia colectiva a la educación,  como proyecto social. En este ensayo nos adentramos en la cuestión del curriculum desde esta segunda perspectiva, y señalamos (apoyándonos en algunos ejemplos específicos de diseños curriculares argentinos) ciertas tensiones en relación a tres ejes: 1. el curriculum como la voz del Estado y de “lo público” en el marco de un fuerte avance de idearios mercantilizantes y gerencialistas para la educación inicial; 2. las formas que adquiere el saber en las formulaciones curriculares, y sus implicancias políticas y pedagógicas y 3. la idea del curriculum como expresión de un sujeto y una sociedad, con las paradojas y contradicciones que habitan esta idea.
Sentidos atribuídos pela coordenação pedagógica ao currículo da educação infantil
Authors: Barroso Fabiana Pinheiro , Santos Sandro Vinicius Sales dos
Published: June 2022

Este texto discute a visão das coordenadoras pedagógicas sobre a organização do currículo da Educação Infantil. Partindo das Pedagogias da Infância, bem como das teorias sobre currículo, analisam-se entrevistas semiestruturadas com seis coordenadoras pedagógicas de Turmalina, Minas Gerais. Os diálogos com as coordenadoras evidenciam que, se, por um lado, elas compreendem a criança como centro das práticas pedagógicas e a brincadeira como momento favorável ao desenvolvimento; por outro, apontam que o currículo sugere prescrições quanto às práticas educativas, embora seja uma construção cotidiana de crianças e de professores. Como apontamentos finais, evidencia-se a coordenação pedagógica como elemento essencial na articulação entre o currículo prescrito e o vivido pelas crianças.
Educação das relações étnico-raciais na formação docente
Authors: Silva Bárbara Rainara Maia , Cruz Silvia Helena Vieira
Published: June 2022

Neste artigo, partilhamos alguns resultados de uma pesquisa que analisou as contribuições do curso de Pedagogia quanto ao tema das relações étnico-raciais na formação inicial de pedagogos/as para a docência na Educação Infantil, a partir da perspectiva de docentes, discentes e egressos/as da Faculdade de Educação da Universidade Federal do Ceará (FACED – UFC). A pesquisa qualitativa utilizou questionários e entrevistas semiestruturadas. Os depoimentos indicam que o atual currículo acentua a dimensão cognitiva e racional da formação e deixa lacunas em relação às especificidades da Educação Infantil, inclusive ao tema enfocado. É urgente, portanto, que a formação contemple os/as estudantes em sua integralidade e promova maior articulação entre Educação Infantil e relações étnico-raciais.
Histórias de aprendizagem e cotidiano
Authors: Da Silva Pecoits Sariane , Kremer Claines , Vasconcelos Queila Almeida
Published: June 2022

Este ensaio teórico tem como objetivo tecer considerações e reflexões sobre Educação Infantil e currículo. O trabalho situa-se teoricamente no campo da Pedagogia da Infância em interlocução com autores que contribuem para problematizar as prescrições curriculares para esta etapa da educação básica. São abordados os conceitos de Cotidiano e Narratividade como fios condutores da discussão, aqui considerados como elementos constitutivos de um Currículo Narrativo para a Educação Infantil. Finaliza-se com uma breve discussão sobre as Histórias de Aprendizagem como uma prática avaliativa que sustenta a articulação de ambos os conceitos na composição de um Currículo Narrativo como anuncio uma educação que valoriza os saberes, os interesses e as experiências de aprendizagem das crianças na escola.
concepções de formação continuada do plano municipal de educação de Criciúma
Authors: Sala Gislene dos Santos , Caldas Morgana Bada , Bittencourt Ricardo Luiz de
Published: June 2022

Este trabalho teve como objetivo identificar e analisar as concepções de formação continuada expressas no Plano Municipal de Educação (PME) de Criciúma, aprovado pela Lei n° 6.514, em 1º de dezembro de 2014. O trabalho está estruturado em três partes: a primeira destina-se à contextualização histórica e legal dos planos de educação; a segunda aborda as concepções teóricas de formação continuada a partir de autores como Tardif e Lessard (2014), Gatti (2008), Magalhães (2019), Nóvoa (2009; 2017), Wagner e Cunha (2019) e Shiroma (2003a; 2003b); e a terceira parte, utilizando-se da análise documental, dedica-se ao estudo das metas e estratégias do PME de Criciúma, que versam sobre a formação continuada de docentes. A análise permitiu identificar a presença de alguns aspectos críticos e humanísticos no PME, mas prevalecem as concepções teóricas de formação continuada com caráter objetivo e tecnicista, que visam a instrumentalizar os professores para atender a demandas específicas e atreladas à superação de índices quantitativos.
Educação escolar indígena em Pernambuco
Authors: Galindo Natally Araujo da Silva , Salles Sandro Guimarães de
Published: June 2022

Desde o início do contato entre indígenas e europeus, sobretudo a partir da segunda metade do século XVI, a educação foi usada pelos colonizadores como ferramenta de controle e dominação dos povos nativos. Esse interesse na “instrução” dos indígenas, portanto, não era desinteressado, mas buscava atender a demandas religiosas, agrário-mercantis, bélicas etc., dos próprios colonizadores. A partir, sobretudo, dos anos 1980, esse modo de o Estado se relacionar com os povos indígenas é colocado em questão, deslocando os paradigmas de controle, assimilação e integração para paradigmas interculturais. O presente artigo versa sobre essas mudanças no contexto de Pernambuco, a partir das mobilizações dos povos indígenas para a efetivação de uma educação escolar indígena específica, diferenciada e intercultural.
Saia da sala de aula!
Authors: Queissada Daniel Delgado
Published: June 2022

Tradicionalmente, a sala de aula tem seu uso inquestionável. Entretanto, seu uso, muitas vezes apenas para uma transmissão passiva de conhecimento pode ter um efeito devastador. O adoecimento profissional de docentes vem aumentando e o desinteresse de alunos se eleva a cada ano, o ensino que poderia ser prazeroso acaba sendo sofrível e solitário. Os conhecimentos devem ser construídos pelos alunos, e não apenas absorvidos. Tais construções são realizadas de várias formas e, em vários lugares. Por isso, a saída da sala de aula é uma estratégia alternativa de ensino. Contudo, é perceptível que novas estratégias, às vezes, sofrem resistências, mas devemos ter em mente que não há apenas uma forma de ensinar, e que métodos onde o aluno construa conhecimentos de forma ativa são extremamente produtivos. Esse trabalho trata-se de uma revisão bibliográfica crítica (passiva) com um referencial teórico baseado, principalmente, em estudos de relevância na área dos últimos 5 anos. Desta forma, espera-se uma ampliação da visão docente em relação as estratégias de ensino/aprendizado que transcendam a sala de aula. Assim, o objetivo desse texto é estimular os docentes a seguirem outros caminhos para a aprendizagem.
