Purpose. To present clinical cases of macular edema associated with central retinal vein thrombosis (CRVT) of various etiologies. Material and methods. A prospective study of patients with macular edema associated with thrombosis of the central retinal vein or its branches in real clinical practice was conducted. All patients underwent a standard ophthalmological examination, as well as optical coherence tomography (OCT), and a biochemical blood test was performed on a patient with suspected macroglobulinemia. Results. In the first clinical case, macular edema was associated with retinovasculitis. The patient was consulted by a rheumatologist, diagnosed with idiopathic dermatomyositis, polymyositis, confirmed seropositive form. A long-term regimen of glucocorticosteroid drugs (Prednisone), courses of lymphosorption was prescribed. Treatment was carried out for macular edema, occlusion of the central nervous system on the background of retinovasculitis: anti-VEGF therapy, retinal laser coagulation. In the second clinical case, macular edema on the background of CRV thrombosis associated with Waldenstrom's disease. It is recommended to monitor and treat the underlying disease with a hematologist. Conclusion. Thus, macular edema occurring against the background of thrombosis of the central nervous system and its branches, having atypical symptoms in the form of exudative retinal detachment, the presence of a bilateral process, young age and the absence of risk factors for the development of retinal vein occlusion, as well as resistance to anti-VEGF therapy requires careful collection of anamnesis taking into account the patient's somatic condition and the presence of other ophthalmological vascular pathology.

Published: April 2023

Purpose. To study the effectiveness and anatomical results of gravitational dislocation of submacular hemorrhages in patients with age-related macular degeneration. Material and methods. We examined 4 patients (4 eyes) with the diagnosis of submacular hemorrhages. The average age of the subjects was 71.45 ± 5.15 years. The duration of the disease was 7determined from the onset of characteristic symptoms to surgical treatment and averaged 7.5 ± 4 days. The maximum corrected acuity averaged 0.02 ± 0.05. According to the data of optical coherence tomography, a high central detachment of the neuro- and pigment epithelium with hemorrhagic contents was determined in patients. In the presence of lens opacity, surgical treatment was started with phacoemulsification of cataracts. All patients underwent pars plana vitrectomy combined with subretinal tissue plasminogen activator (t-PA) and intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection without any tamponade. The patients were advised to take supine position postoperatively in order t-PA to liquefy the haemorrhage, for 1 h; after which they were positioned upright or lying down on the temporal side of the affected eye, for 3 days. Results. In the early surgical period, there was a tendency to increase the maximum corrected visual acuity (MCI): on the 7th day after the first stage of treatment, it was 0.23 ± 0.06 (p < 0.05 compared with the indicators before treatment). The displacement of the blood clot from the central area of the retina, with the correct positioning of the patient, occurred within 5.87 ± 1.9 days. Lysis of the submacular clot was observed for 14 ± 1.53 days. After 3 loading injections carried out within 1.2 and 3 months after the operation, the MCI increased to 0.4 ± 0.2. Conclusion. Microinvasive subtotal vitrectomy with subretinal injection of Prourokinase, with proper positioning of the patient, help gravitational dislocation of submacular hemorrhages and is an effective treatment method in patients with age-related macular degeneration.

Н. Михалева известна среди читателей, прежде всего, как поэтесса. В поле зрения критиков тоже находится главным образом ее поэзия. Между тем в творчестве Сайа представлен целый ряд прозаических произведений. В настоящей статье рассматривается жанровая специфика малой прозы писательницы, которая включает психологические и нравоописательные рассказы, а также очень своеобразные новеллы-рефлексии. Что касается повестей, то интерес представляют не только их жанрово-композиционные особенности, но и специфические приемы и принципы персонификации в «Голубом подснежнике» и «Уйгуре». Таким образом, исходя из ценностных критериев при анализе прозаических произведений Н. Михалевой, авторы приходят к выводу, что художественная проза Сайа по своему уровню по крайней мере не уступает ее поэзии и относится к лирическому направлению в современной якутской литературе.

Published: April 2023

The study aims to suggest fundamental alternatives for future research on the eco-friendly performance of employees in food service companies by investigating the relationship between ethical leadership, environmental, organizational culture, and eco-friendly performance in food service companies. Ethical leadership in this study is operationalized as temperance, courage, fairness, and prudence, while environmental, organizational culture, and eco-friendly performance are conceptualized as single factors. The study was limited to employees of food service companies in the Seoul area, and a convenience sampling method was used to conduct an online (Google) survey. The hypothesis was tested through a sequence of statistical analyses, including frequency analysis, confirmatory factor analysis, discriminant validity, and structural equation model analysis. This study contributes to the existing literature by examining the influence of ethical leadership, environmental, organizational culture, and eco-friendly performance in food service companies. The study's results support existing theoretical research and provide practical implications for food service companies' operation plans and employees' eco-friendly performance.
Robust Chemoenzymatic Synthesis of the Keratinimicin Aglycone Facilitated by the Structure and Selectivity of OxyB

Published: April 2023

The emergence of multidrug-resistant pathogens poses a threat to public health and requires new antimicrobial agents. As the archetypal glycopeptide antibiotic (GPA) used against drug-resistant Gram-positive pathogens, vancomycin provides a promising starting point. Peripheral alterations to the vancomycin scaffold have enabled the development of new GPAs. However, modifying the core remains challenging due to the size and complexity of this compound family. The recent successful chemoenzymatic synthesis of vancomycin suggests that such an approach can be broadly applied. Herein, we describe the expansion of chemoenzymatic strategies to encompass type II GPAs bearing all aromatic amino acids through the production of the aglycone analogue of keratinimicin A, a GPA that is five-fold more potent than vancomycin against Clostridioides difficile. In the course of these studies, we found that the cytochrome P450 enzyme OxyBker boasts both broad substrate tolerance and remarkable selectivity in the formation of the first aryl ether crosslink on the linear peptide precursors. The X-ray crystal structure of OxyBker, determined to 2.8 Å, points to structural features that may contribute to these properties. Our results set the stage for using OxyBker broadly as a biocatalyst toward the chemoenzymatic synthesis of diverse GPA analogues.
Controlling intramolecular and intermolecular electronic coupling of radical ligands in a series of cobaltoviologen complexes

Published: April 2023

Controlling electronic coupling between two or more redox sites is of interest for tuning the electronic properties of molecules and materials. While classic mixed-valence (MV) systems are highly tunable, e.g., via the modular organic bridges connecting the redox sites, metal-bridged MV systems are difficult to control because the electronics of the metal cannot usually be altered independently of redox-active moieties embedded in its ligands. Herein, we overcome this limitation by varying the donor strengths of ancillary ligands in a series of cobalt complexes without directly perturbing the electronics of viologen-like redox sites bridged by the cobalt ions. The cobaltoviologens [1X-Co]n+ feature four 4-X-pyridyl donor groups (X = CO2Me, Cl, H, Me, OMe, NMe2) that provide gradual tuning of the electronics of the bridging CoII centers, while a related complex [2-Co]n+ with NHC donors supports exclusively CoIII states even upon reduction of the viologen ligands. Electrochemistry and IVCT band analysis reveal that the MV states of these complexes have electronic structures ranging from fully localized ([2-Co]4+; Robin-Day Class I) to fully delocalized ([1CO2Me-Co]3+; Class III) descriptions, demonstrating unprecedented control over electronic coupling without changing the identity of the redox sites or bridging metal. Additionally, single-crystal XRD characterization of the homovalent complexes [1H-Co]2+ and [1H-Zn]2+ revealed radical-pairing interactions between the viologen ligands of adjacent complexes, representing a type of through-space electronic coupling commonly observed for organic viologen radicals but never before seen in metalloviologens. The extended solid-state packing of these complexes produces 3D networks of radical π-stacking interactions that impart unexpected mechanical flexibility to these crystals.
DARK MATTER OF IMAGES IN THE SITUATION OF CONTAGIOUS RESONANCE
Authors: Perepelytsia Oleh , Khrabrova Olha
Published: April 2023

The article conceptualizes the ontological separation in the situation of "contagious resonance", which is set in particular by the pandemic. There is a shift in the mass consciousness of the terrifying images that form a kind of "dark matter" of the materialist view of the modern capitalist world and embody in a certain cultural and historical perspective of the paradigm of life, power. Reveals four macro-images characteristic of the coordinate system of the modern world: demon, zombie, vampire and werewolf. They reveal as a kind of substance of this world the separation-partition that allows the following processes: alienation, appropriation, consumption, absorption, exploitation, rotation, assimilation, satisfaction, exchange, information, knowledge, transformation, desolation, infection, vaccination. This is a paradoxical state of mass consciousness caused by a pandemic, when the penetration of "infinitesimally" leads to extraordinary social processes of separation, distancing, alienation, which is represented by horrible macro images, diagrams of which are presented in the article. The main principle of the study is the principle of complementarity, which allows you to build such diagrams, exposing the complementarity, intertwining and compatibility of images of zombies, demons, vampires and werewolves in nonlinear perspective. The diagrammatic approach, therefore, allows you to highlight the eerie, incredible as everyday.

Zombies and vampires are presented as paradigmatic for (post)modern culture, characterized by a special boundary state between death and immortality. The demon and the werewolf return the fears inherent in the pre-capitalist, archaic image of the world, when man was placed between the divine and animal dimensions. It is noted that the zombie figure embodies the grassroots phenomena of today: dead labor, industrial exploitation, consumerism, mass infection, advertising, information. A vampire marks a class gap and is the epitome of choice and the privilege it confers. The demon and the werewolf represent the fears present in the conservative and ecological consciousness. The article identifies four transversals that dissect the multiplicity of processes characteristic of modern society: zombies / infection, which characterizes the processes of transmission of everything from information to virus, vampire / vaccination as access to a set of privileges, demon / desolation, as separation of mental and physical , werewolves / transformations as interpenetration of different types of life.
“It’s not sexy” and “I can’t control it”: Young women's constructions of heterosex with Inflammatory Bowel Disease
Authors:   , Boyle Brianagh
Published: April 2023

An inflammatory bowel disease (IBD) can negatively impact sex due to abdominal pain, faecal incontinence, symptom uncertainty and poor body image. The way women make meaning of heterosex is grounded in available cultural discourses associated with sexuality and femininity (Moran & Lee, 2014). Previous research on sexual intimacy experiences for women with IBD fails to consider the wider social and cultural environment these women are situated within. There is a need to understand how women negotiate and make meaning of heterosex in dating relationships with IBD. This study explored how young women with IBD constructed their experiences of heterosex in dating relationships. In-depth semi-structured interviews were conducted with ten self-identified women who were single or dating men and between the ages of 18-35 who were diagnosed with IBD. I adopted a material-discursive theoretical framework underpinned by a critical realist epistemology. A reflexive thematic analysis was used to explore how these women constructed and navigated their IBD in relation to heterosex in dating relationships with men. From my analysis, I identified two overall themes in which women constructed heterosex regarding their IBD: disruption to the sexual youth, and the feminine sexual body. In the theme ‘disruption to the sexual youth’, women talked of how their IBD prevented them from being able to be young and sexually free. These women also positioned their IBD journey as a process of self-discovery, in which they discovered what they needed most at that point in their life. In the theme ‘the feminine sexual body’, women talked of having a failed feminine sexual body, positioning it as ‘dirty’ and ‘unpredictable’. These women talked about managing and preparing their bodies before and during sex. Finally, most women talked of reaching a point of self-acceptance with their IBD bodies. The findings of this study suggest that IBD can be seen to disrupt dominant discourses of sexuality and femininity in youth, in which young women were unable to achieve ideals around femininity, a sexual youth and heterosexual. These findings highlight the relevance and need for open conversations within research and health settings for women with IBD, to shift social taboos and ensure women have their sexual health needs met.
Features of creating a system of simultaneous built-in testing of deformation and temperature of composite structures by fiber-optic sensors
Authors: Fedotov M. Yu.
Published: April 2023

This article describes the relevance of improving existing and creating new effective methods of non-destructive testing and technical diagnostics of highly loaded aircraft structures made of polymer composite materials to ensure safe operation. Approaches to the creation of efficient systems for the simultaneous embedded testing of deformations and temperature of structures made of polymer composite materials by an optical method using embedded fiber-optic sensors based on fiber Bragg gratings are considered. The world experience in creating such systems, the methodology of non-destructive testing are analyzed, taking into account the creation of a spatial topology of fiber-optic sensors in a real product. It is shown that to solve this problem, it is most expedient to use the method of two optical fibers with different sensitivity to deformation and temperature, or to one of these parameters. The results of experimental studies on the simultaneous control by the proposed method of deformation and temperature of a structurally similar sample from a carbon composite processed by a vacuum method from a prepreg are presented. It has been established that the use of a quadratic model for optical control of structurally similar samples of carbon composite makes it possible to increase the accuracy of deformation and temperature measurements in comparison with the linear control model. It is confirmed that the proposed experimental technique allows for simultaneous control of deformation and temperature of structurally similar samples from carbon composites, while it can be adjusted and adapted to the actual operating conditions of a particular structure.

Published: April 2023

In recent years, the number of space objects located in near-Earth outer space, especially in the near operational zone, has increased significantly due to the build-up of space groupings, including dual-use (for example, Starlink) and the remnants of their vital activity (space debris). This factor increases the importance of the task of recognizing and classifying space objects by type in the shortest possible time and entering them into the main catalog of space objects. The developed methodology allows automated analysis of optical images of space objects using software to solve the problem of their recognition and classification by type using a convolutional neural network. The purpose of the study is to increase the efficiency of processing and analysis of optical images of spacecraft. The experimental results of the study confirm the achievement of the research goal. The developed methodology contributes to the development of software and hardware for image processing and can be used in calculations and data preparation for information support of interested officials. For the first time, a training set for a convolutional neural network has been prepared using real optical images of spacecraft obtained in the visible range.

Published: April 2023

To effectively receive a useful broadband signal, it is necessary to compensate for distortions caused by the complex frequency-dependent coefficient of the receiving and transmitting antenna, multiplicative interference and noise from the heterogeneity of the propagation medium, additive interference and noise. Using only correlation processing under certain conditions will not allow receiving a useful broadband signal with the required quality. The article develops a mathematical model of spatio-temporal processing of broadband signals in satellite broadband access systems, showing that spatio-temporal processing should be carried out in two stages. At the first stage, space-time processing is carried out in the channel adaptively to the antenna array based on the formation of a complex frequency-dependent vector of weighting coefficients, which should change with a change in the signal-interference situation in real time, taking into account the change in the direction of radiation sources. At the second stage, correlation processing of the broadband signal is performed based on the use of long-length code sequences. This model is the basis for the development of methods for the formation and correlation (temporal) processing of broadband signals and methods of spatio-temporal processing of broadband signals under conditions of intentional and unintentional exposure. Based on the presented mathematical model of spatio-temporal processing of broadband signals, the main directions of increasing the noise immunity of radio-electronic systems are determined.

Análisis tecnológico de la obsidiana de Tajamar
Authors: Falcón Revelo Wilmer Isaac
Published: April 2023

Este trabajo examina dos ocupaciones no consecutivas del sitio Tajamar, ubicado en Pomasqui, en la actual ciudad de Quito. Tajamar registra una ocupación Formativa datada entre los años 1191 – 850 cal a.C., y una ocupación de Integración (600 – 1423 cal d.C.). Ambas ocupaciones presentan obsidiana, material lítico que ha sido analizado para inferir la tecnología con el que fue trabajado, las fuentes desde donde la obsidiana fue extraída y su posible uso. Las dos ocupaciones de Tajamar fueron examinadas bajo la perspectiva arqueológica de cadenas operativas y con una metodología morfo-tecnológica. Esta metodología, además de abarcar más posibilidades con respecto al material, puede ser comparada entre sitios y sienta un precedente a los futuros estudios líticos en el Ecuador. Esta investigación es un ejemplo pertinente de la relación que tiene el ser humano dentro de un entorno que es transformado culturalmente y que también exige dinámicas adaptativas.

Después de la catástrofe: investigando un programa funerario del Periodo Desarrollo Regional en Salango, provincia de Manabí, Ecuador.
Authors: Lunnis Richard
Published: April 2023

Se realizaron nuevos descubrimientos significativos durante las excavaciones de rescate conducidas en 2015–2016 en Calle 22, Salango, en la costa sur de la provincia de Manabí, Ecuador. Entre estos estaba la presencia de dos montículos funerarios que pueden atribuirse a una fase Guangala muy temprana previamente no documentada del Período Desarrollo Regional. Los entierros, en su mayoría de bebés, mostraban marcadas patologías indicativas de una variedad de problemas de salud. Y en lo que parece ser un ritual de entierro único a nivel mundial, dos bebés portaron como cascos los cráneos modificados de otros niños. La investigación en curso sugiere que los montículos funerarios y los entierros en Calle 22 eran parte de un programa de entierro más grande centrado en una plataforma ceremonial Engoroy Tardío situada 150 m. al sur, y que este programa siguió y fue una respuesta a una caída catastrófica de ceniza volcánica. Este artículo describe la evidencia arqueológica descubierta, el proceso de investigación y análisis realizado hasta el momento, y las razones para suponer que el programa de entierro se llevó a cabo en respuesta a la caída de ceniza.

La presente investigación se realizó en la provincia de Loja, sitio arqueológico Tambo Blanco (San Lucas, Ecuador). La evidencia arqueológica se representa en material lítico y cerámico diseminado en la superficie; además de, estructuras como terrazas escalonadas, palacio central, kallanka, kollkas, Kapac-Ñan, entre otras, que denotan una ocupación prehistórica de importancia por su materialidad. Actualmente, las actividades humanas y los factores climáticos provocan una constante alteración y destrucción del sitio, a causa de una supuesta falta de interés y conciencia sobre el patrimonio arqueológico en la región, siendo esta una problemática de tipo social e investigativa. Por ello, el objetivo de este estudio fue reconocer el estado actual de los vestigios arqueológicos y, a su vez, indagar sobre las percepciones y los significados que los pobladores asignan a los elementos patrimoniales de la zona, mediante la aplicación de cartografía social y entrevistas a profundidad. Con esta investigación se generó un registro de la materialidad presente en Tambo Blanco y los usos actuales que se hace del sitio arqueológico.

ETHNOMATHEMATICS EXPLORATION OF THE MALAKA CULTURE OF THE TETUN TRIBE COMMUNITY IN MALAKA REGENCY
Authors: Nahak Roswita Lioba , Feka Viktorius Paskalis
Published: April 2023

The culture of giving children called ‘matamusan’ from the Tetun tribe is a local culture that should be for its authenticity and sacredness. The procession of determining the children of ‘matamusan’ contains ethnomathematical values not realized by the cultural legatees. This research aims to explore the ethnomathematical elements in ‘matamusan’ culture. In addition, this research can be beneficial at developing context-based mathematical learning materials and a reference in developing the operational curriculum of the education units in the autonomous learning curriculum, particularly in elementary schools. This research employs a qualitative-exploratory method using an ethnographic approach, while observation and interviews are used as techniques to collect data. Data analysis uses data reduction, data presentation, and conclusion. The results of this research show that there are six mathematical concepts  in the cultural procession of determining ‘matamusan’ children: (1) the concepts of one-dimensional geometry, namely a line consisting of horizontal lines, parallel lines, and acute angles, and two-dimensional geometry, namely rectangles and rhombus. (2) the concept of counting; 3) the concept of the median; 4) the concept of the unit of time; 5) the concept of the unit of weight and; 6) the concept of currency, which can be used to develop teaching materials on mathematical content, especially in elementary schools whose implementation is in the form of context-based mathematical problems..
RUSSIA - KAZAKHSTAN RELATIONSHIPS IN THE POST-CRIMEA PERIOD. STAGE OF TURBULENCE
Authors:   St. Petersburg State University, Meshcheryakov Konstantin E.
Published: April 2023

The article studies the evolution of the Russian-Kazakhstani relations at the first stage of the post-Crimea period (March 2014 – August 2016). Based on a wide range of official sources and periodicals, it identifies the main trends and issues of bilateral cooperation in the political, military and economic spheres, and at the interregional level. It determines the factors that influenced interaction between Moscow and Astana. Particular attention is paid to the role of the presidents of Russia and Kazakhstan in promoting and strengthening their strategic partnership. The author concludes that the period under consideration was a time of serious challenges for bilateral relations, which for the first time in history, entered a phase of prolonged turbulence. After the “Crimean Spring”, the Kazakhstani leadership faced a dilemma: to maintain the existing level of cooperation with Russia in losing the trust of its Western partners or lower the degree of interaction with Moscow to strengthen its ties with Western states. The situation worsened in November 2015, when a sudden conflict between Russia and Turkey plunged the relations between Moscow and Astana into a deep crisis. For several months, the political dialogue between Russia and Kazakhstan was reduced to a minimum, and the military-political alliance of the two states was in danger of collapse. Nevertheless, in May 2016, Astana made the only correct choice in favor of maintaining the special status of its relationships with Moscow. The two sides immediately re-established their ties across the full spectrum of their cooperation. Their strategic partnership entered a new stage of development, characterized by a relative stabilization on the background of an unfavorable international environment

Destaca nas considerações a importância dos estudos voltados ao RIs e seu papel de coletar, gerir, manter documentação da instituição, ofertando serviços.
O Progresso na Implantação da Transparência Informacional Ativa no Estado de Roraima: o caso do IFRR e da UFRR
Authors: Rosa Tatiana Costa , Baptaglin Leila Adriana
Published: April 2023

No Brasil a Lei nº 12.527/2011, conhecida como acesso à informação (LAI) vem evoluindo no cumprindo de suas obrigações, onde o acesso passa a ser visto como regra e o sigilo exceção. Contudo, no extremo norte do país, especificamente no Estado de Roraima é possível observar que um percurso ainda tem de ser trilhado para a implantação total da Lei. Com o intuito de darmos os primeiros passos na busca por respostas sobre o andamento da implantação da LAI em Roraima, selecionamos duas instituições públicas federais voltadas à educação: o Instituto Federal de Roraima (IFRR) e a Universidade Federal de Roraima (UFRR), onde objetivamos averiguar a atual situação da transparência ativa, contemplada nos Artigos 7º e 8º do Decreto nº 7.724/2012 que regulamenta a LAI. Buscamos assim, apresentar os progressos e dificuldades destas duas instituições na implantação da LAI.

Apresenta uma estrutura sistemática como sugestão para a construção de um tesauro na área de Física, contendo os principais termos descritores utilizados na categorização, classificação e indexação das publicações.
Revolução Informacional e os Avanços Tecnológicos da Informática e das Telecomunicações
Authors: Roza Rodrigo Hipólito
Published: April 2023

O presente artigo tem o objetivo de discutir a relação entre a revolução informacional e os avanços da informática e das telecomunicações, que convergiram para uma mesma base tecnológica. Para compreensão da revolução informacional, parte-se dos fenômenos de explosão da quantidade de informação e implosão do tempo, que resultaram em elevados fluxos de informação. Na sequencia, o artigo aborda a nova forma de organização da atual sociedade, denomina sociedade da informação ou do conhecimento por alguns autores, o conceito de informação sob a perspectiva da ciência da informação, bem como o papel da evolução tecnológica neste processo de transformação social. Conclui-se que a revolução informacional e os avanços tecnológicos estão intimamente interligados e que seus efeitos continuam a exercer forte influência sobre a sociedade e a economia.

Authors: Goularti Filho Alcides
Published: April 2023

O objetivo deste artigo é descrever e analisar a trajetória da estatizaçãoda telefonia em Santa Catarina e as ações e investimentos da Companhia Catarinensede Telecomunicações (COTESC) entre 1965, quando foi criado o ConselhoEstadual de Telecomunicações, e 1973, quando a COTESC foi federalizada. O artigoinicia com uma breve reflexão sobre estatização e privatização, em uma tentativade desvinculá-las de ideologias pré-concebidas. Em seguida, traz um panoramageral do processo de estatização da telefonia no Brasil e as iniciativas da CompanhiaCatarinense de Telefonia (CTC) para implantar uma rede estadual de telefonia.

A Economia Institucional Original no Brasil
Authors: Brites Maríndia , Almeida Felipe
Published: April 2023

A Economia Institucional Original é um segmento do pensamento econômico genuinamente estadunidense. No entanto, hoje, o institucionalismo original “migrou” para outros países. O objetivo desse estudo é analisar se há uma vertente da Economia Institucional Original no Brasil. Para tal identificamos quem são os institucionalistas originais que atuam no Brasil e analisamos o tipo de institucionalismo que eles produzem – seus artigos científicos – e o tipo de institucionalismo que eles reproduzem – o programa de suas disciplinas. Os nossos resultados apontam que não é possível afirmar que existe uma vertente da Economia Institucional Original no Brasil, mas há institucionalistas originais brasileiros – que pode ser um primeiro passo para uma vertente institucionalista original brasileira – e há brasileiros que lidam com Economia Institucional de forma mais abrangente que Institucionalismo Original.
A questão agrária brasileira na obra dos grandes pensadores do século XX e a fronteira agrícola do Centro-Oeste: as possibilidades de debate e interlocução
Authors: Soares Herick Vazquez
Published: April 2023

O trabalho analisa parte do debate acerca da questão agrária brasileira nas obras de importantes pensadores brasileiros do século XX acerca do tema: Alberto Passos Guimarães, Caio Prado Júnior, Celso Furtado, Ignácio Rangel e Milton Santos, buscando estabelecer um diálogo entre as análises e categorias desses autores com o processo de constituição do Complexo Agroindustrial brasileiro e da consolidação da região Centro-Oeste do Brasil como região produtora do agronegócio entre as décadas de 1960 e 1980. Nesse período, fatores decisivos - urbanização, industrialização, pesquisas tecnológicas, políticas econômica e territorial - estiveram combinados de modo a possibilitar o estabelecimento de uma “vocação” agropecuária que articulou a região Centro-Oeste à divisão regional do trabalho e sua efetiva incorporação ao capitalismo brasileiro, colocando a questão agrária brasileira em novo patamar.
Connections between achievement emotions and covariational reasoning: The case of Valeria
Authors: Nava Guzmán Cristian , García González María Del Socorro , Aguilar Mario Sánchez
Published: April 2023

This research explores the link between achievement emotions and covariational reasoning, a type of mathematical reasoning involving two variables. The study employs a case study approach, focusing on a high school calculus student named Valeria, and develops a theoretical framework based on the control-value theory and levels of covariational reasoning. The results reveal that Valeria’s ability to coordinate variables and her perceived importance of solving mathematical problems influence her experience of achievement emotions, including enjoyment and frustration. The case study enables the creation of a hypothetical model that explains how students feel achievement emotions when tackling mathematical tasks that require covariational reasoning. The study highlights the significance of comprehending the interplay between emotions and mathematical reasoning to cultivate advanced cognitive and emotional abilities. This research is essential in bridging the gap between emotions and mathematical reasoning, a topic that has been previously overlooked in research on the affective domain.
