Reflexões sobre o agronegócio e a exposição à pandemia da covid-19 nas terras indígenas Guarani Kaiowá em Mato Grosso do Sul
Authors: Rios Cecilia Almeida , Urquiza Antonio Hilário Aguilera , Prado José Henrique
Published: June 2022

O etnocídio é uma realidade cada vez mais próxima à medida que a covid-19 se espalha por Mato Grosso do Sul, MS, região onde predomina a etnia Guarani Kaiowá, a segunda maior etnia indígena do Brasil. Segundo o relatório anual apresentado pelo Conselho Indigenista Missionário (CIMI), Mato Grosso do Sul é o estado onde mais se registra violência contra os povos indígenas. Um dos principais elementos para se entender esta escalada de violências é justamente a falta de demarcação de seus territórios tradicionais, afinal, com aldeias populosas e sem o rápido afastamento dos indígenas que estão inseridos como força de produção do agronegócio em Mato Grosso do Sul, o coronavírus encontrou o cenário perfeito para se disseminar de forma rápida. Neste texto de caráter ensaístico, pretendemos demonstrar uma visão sobre a vulnerabilidade desses povos à covid-19, que se agrava com o desmonte das políticas de saúde indígena, o sucateamento do órgão indigenista oficial e a desastrosa condução das ações pelo governo federal durante a pandemia. O presente estudo tem caráter crítico e reflexivo, e procura contribuir para a compreensão do contexto sociocultural e político em que os povos indígenas estão inseridos, usando como aporte metodológico a pesquisa bibliográfica e documental, assim como a experiência de vida e campo dos autores.

Authors: Pedro Leide da Silva
Published: June 2022

Este texto apresenta a formação do conhecimento do alimento tradicional kaiowa, que é fruto da herança deixada por nossos anciões. Para algumas famílias este conhecimento é ainda muito usado, de forma que muitas famílias continuam mantendo essa cultura do conhecimento tradicional, do costume e do modo de alimentar seus filhos com seu alimento cultural. Por outro lado, esses conhecimentos muitas vezes já foram afetados em alguma família, onde não querem mais usar esse conhecimento. Assim, esse trabalho buscou valorizar essa herança e riqueza de conhecimento e do costume que ainda está muito ativo em algumas famílias do guarani e kaiowa.

BAROK RESİM SANATINDA İSKENDERİYELİ AZİZE CATHERINE
Authors: IŞIK Vildan
Published: June 2022

Erken Hristiyanlık martirlerinden biri olarak kabul edilen İskenderiyeli Azize Catherine, Bakire

Meryem’den sonra Hristiyanlıkta en fazla resmedilen ‘kutsal bakire’ figürüdür. On üçüncü yüzyılda

derlenen Altın Efsane kitabı, azizeye ilişkin efsanelerin yaygınlaşmasında önemli rol oynar. Orta Çağ’dan

beri efsanesi genişleyen ve değişen hikâyelerle donatılarak kültleştirilen Catherine; soyluluğu, felsefi bilgisi,

belagatı, cesareti, zekâsı, çarpıcı güzelliği ve kararlı inancına dair hikâyeleri ile yüzyıllarca sanata konu olur.

Catherine’in Orta Çağ’ın sonlarına doğru başlayan popülerliği, Rönesans ve Maniyerist dönemlerin ardından

Barok dönem boyunca da Katolik Kilisesi’nin desteğini alarak devam eder. Catherine’in; portreleri, İsa ile

yaptığı mistik evliliği, filozoflarla ihtilafı, pagan idollere tapmayı reddetmesi ve martirliğinin yanı sıra kutsal

kabul edilen diğer figürlerle birlikte gösterildiği sayısız tasviri yapılır. Bu çalışmada müze ve galerilerde yer

alan İskenderiyeli Azize Catherine’in Barok dönemde yapılmış tuval üzeri yağlıboya tablolarının araştırılması

ve ikonografik olarak incelenmesi amaçlanmıştır. Genişletilen ve/veya değiştirilen hikâyelere dayanan bu

resimler, kültleştirilen azizenin şüpheli tarihsel kişiliğine rağmen uzun yıllar hem kilise sunaklarını hem de

aristokratların duvarlarını süslemiştir.

ÇAĞDAŞ TÜRK OYUN YAZARLIĞINDA BİR DIŞLAMA PRATİĞİ OLARAK HOMOFOBİ
Authors: UZUNDEMİR Ezgi , BELKIS Özlem
Published: June 2022

1960’larda Weinberg tarafından tanımlanan homofobi terimi psikoloji, sosyoloji ve hukuk alanlarında

irdelenen bir meseledir. Günümüzde cinsiyete dayalı ayrımcılığın bir dışlama pratiği olarak tanımlanan

homofobi, etkileri ve sonuçlarıyla farklı alanlarda incelendiği gibi tiyatro alanında da işlenmiş, bu bağlamdaki

deneyimler, sonuçlar, ezilme ve dışlama pratikleri sahneye getirilmiştir. Avrupa ve Amerika tiyatrosunda

homofobiyi ele alan oyunların izleri 1930’larda görülmeye başlar, ancak homofobiyi çarpıcı şekilde işleyen

metinler için 1960’ları beklemek gerekir. Türk oyun yazarlığında ise homofobiyi işleyen oyunlara rastlamak

ancak 2000 sonrasında mümkündür. Peki 2000 sonrası Türk tiyatrosunda homofobik tutum ve davranışlar

hangi bağlamlarda nasıl işlenmiştir? Bu metinlerde homofobiye ilişkin tahakküm ve direnme pratikleri

nelerdir? Çalışmamızın amacı bu soruları yanıtlayarak 2000 sonrası Türk oyun yazarlığında cinsiyete

dayalı ayrımcılık ve homofobi temasının nasıl işlendiğini örneklerle sunmaktır. 2000 sonrasında yazılmış

oyunlardan homofobiyi ele alma, sahnelenme ve yayınlanma kriterleri gözetilerek 12 oyun seçilmiştir.

Oyunlar homofobinin teorik zemini bağlamında incelenmiş, konunun ele alınışı açısından Bireyin Kendisini

Dışlaması, Heteronormativiteden Doğan Sosyal Dışlama ve Kamusal Alanlardan Dışlama şeklinde üç

başlıkta kategorize edilebileceği görülmüştür. Sonuçta oyun yazarlarının homofobiyi aşılması gereken bir

dışlama biçimi olarak gördükleri; bazı oyunlarda direnme stratejisi üretilirken, bazılarında kabullenici bir

tutum sergilendiği görülmüştür. Direnme üreten yazarlardan bazılarının, homofobiyi komedi aracılığıyla,

bazılarının ise trajik öğelerle aşmaya çalıştığı görülmüştür.

Published: June 2022

The 21st-century national education paradigm requires students to have new abilities, such as critical thinking ability. However, students' critical thinking skills are still low. Likewise, interest in studying physics is still low. Physics is often considered a difficult subject, discouraging interest in studying physics. This study aims to examine the effect of a problem-based approach and experimental media on the interest in learning physics and the critical thinking skills of class XI high school students using SEM analysis. This research was conducted at senior high school on 4 Jember. The research data were collected using a questionnaire tested for validity and reliability. Furthermore, the data were analyzed using SEM analysis, developing a theoretical model, developing a flow chart, and evaluating the goodness of fit criteria. The results obtained, the problem-based approach has a significant effect on the interest in learning physics, the media for the experimental tool has a significant effect on the interest in learning physics, the problem-based approach has a significant effect on students' critical thinking skills, and the media for the experimental tool has a significant effect on the critical thinking skills of grade XI high school students. In addition, it was found that the interest in learning physics was able to mediate the effect of a problem-based approach on critical thinking skills and the influence of experimental media on critical thinking skills. So we can conclude that each dependent variable and the independent variable influence each other significantly.

Published: June 2022

Students' analytical thinking skills are still lacking, causing students' understanding of physics lessons to be less than optimal. The research was conducted to examine the effectiveness of direct current electric video with an inquiry approach to students' analytical thinking skills and student responses to the video. The research method applied in this research is quasi-experimental with the research design of Nonequivalent Control Group Design. The sampling technique is purposive sampling data collection techniques using analytical thinking skills tests and questionnaires to video tutorials responses. The data analysis technique uses parametric quantitative analysis. The results of the analysis of hypothesis testing on the data of analytical thinking skills that had been carried out showed that the video tutorial learning media has not been effective in improving students' analytical thinking skills, while the results of student responses to direct current electric video tutorial learning media obtained a percentage of 70.67% and classified as good category. Students' analytical skills require more intensive practice and challenging routine assignments. Students' interest in the tutorials provided can only increase motivation to be involved in learning. The implications of this research can focus on innovative video tutorials on contextual physics experiments in life and more challenging experiments.
Adaptive hybrid activation function for deep neural networks
Authors: Bodyanskiy Yevgeniy , Kostiuk Serhii
Published: June 2022

The adaptive hybrid activation function (AHAF) is proposed that combines the properties of the rectifier units and the squashing functions. The proposed function can be used as a drop-in replacement for ReLU, SiL and Swish activations for deep neural networks and can evolve to one of such functions during the training. The effectiveness of the function was evaluated on the image classification task using the Fashion-MNIST and CIFAR-10 datasets. The evaluation shows that the neural networks with AHAF activations achieve better classification accuracy comparing to their base implementations that use ReLU and SiL. A double-stage parameter tuning process for training the neural networks with AHAF is proposed. The proposed approach is sufficiently simple from the implementation standpoint and provides high performance for the neural network training process.

Authors: Nedashkovskaya Nadezhda , Androsov Dmytro
Published: June 2022

Encoder-decoder neural network models have found widespread use in recent years for solving various machine learning problems. In this paper, we investigate the variety of such models, including the sparse, denoising and variational autoencoders. To predict non-stationary time series, a generative model is presented and tested, which is based on a variational autoencoder, GRU recurrent networks, and uses elements of neural ordinary differential equations. Based on the constructed model, the system is implemented in the Python3 environment, the TensorFlow2 framework and the Keras library. The developed system can be used for modeling continuous time-dependent processes. The system minimizes a human factor in the process of time series analysis, and presents a high-level modern interface for fast and convenient construction and training of deep models.
Mathematical modeling of the contact interaction of two elastic transversely isotropic half-spaces, one of which contains a near-surface groove of an elliptical section
Authors: Kirilyuk Vitaly , Levchuk Olga , Gavrilenko Valeriy
Published: June 2022

On the basis of a mathematical model, the problem of compression of two elastic transversely isotropic half-spaces, one of which contains a shallow near-surface groove of an elliptical section, is considered. The solution to the problem is obtained using the Elliott representation for a transversely isotropic body in terms of harmonic functions, classical harmonic potentials and reducing the boundary value problem to considering an integro-differential equation with an unknown domain of integration. As a special case, the obtained analytical expressions yield the basic parameters of the contact of transversely isotropic half-spaces in the presence of an axisymmetric groove in one of them, as well as the parameters of the contact interaction of two elastic isotropic half-spaces, one of which contains an elliptical cross-section groove. Numerical results are obtained, the influence of elastic properties of half-spaces, geometrical parameters of groove and loading on contact interaction and closing of the gap between bodies is studied.
Pneumatic Shape and Drag Scaling Laws of the Dandelion
Authors: Sun Bohua , Guo Xiao-Lin
Published: June 2022

The common dandelion uses a bundle of drag-enhancing bristles (the pappus) that enables seed dispersal over formidable distances; however, the scaling laws of pneumatic/aerodynamic drag underpinning pappus-mediated flight remains unresolved. In this paper, we will study the pneumatic/aerodynamic shape of dandelion and the scaling law of resistance, and find that the drag resistance coefficient is proportional to the -2/3 power of the dandelion pappus Reynolds number. As a by-product, the terminal velocity analytical expression of the dandelion seed is also obtained.
Catch Composition, Seasonality and Biological Aspects of Sharks Caught in the Ecuadorian Pacific
Authors: Briones-Mendoza Jesús , Mejía Diego , Carrasco-Puig Pol
Published: June 2022

Although sharks have a fundamental role in maintaining the balance of aquatic ecosystems, exerting a great influence at lower levels, their populations are declining worldwide due, to a large extent, to overfishing. Of the 64 species registered in Ecuador, from January to December 2019, 19 species were recorded in Manta from 15455 captured individuals, with the family Carcharhinidae being the family most present in the catches (69.4%), and the most abundant species was Prionace glauca (57.9%). In the case of threatened species, such as Carcharhinus longimanus, Sphyrna lewini and Sphyrna zygaena, a greater presence of immature specimens was observed in landings, suggesting a possible existence of nursery areas. However, information on the composition and biological aspects of shark species in the Ecuadorian Pacific is very scarce. Therefore, research on the characteristics of life history (age, growth and maturity) are of utmost importance for the analysis evolution of the populations that are being exploited, especially in developing countries, where this information is very scarce, causing inadequate management of fishery resources.

Authors: Heidari Parviz , Puresmaeli Fatemeh , Mora-Poblete Freddy
Published: June 2022

Magnesium transporters (MGTs) play a prominent role in the absorption, transport and storage of magnesium in plant cells. In the present study, MGT gene family members were identified and characterized in two species of cucurbitaceae, including C. sativus and C. lanatus. 20, 19, and 20 MGT genes were recognized in C. lanatus, C. sativus, and C. melo, respectively. According to physicochemical properties, the members of each sub-class of MGTs in the species of cucurbitaceae showed the close relationship. Proteins from NIPA were identified as hydrophilic proteins with high stability. Based on phylogenetic analysis, MGT family members were classified into three groups, and NIPAs showed more diversity. Besides, duplication events were not identified between the MGT members in C. lanatus, and C. sativus. According to pocket analysis, residues such as L, V, S, I, and A were frequently observed in the binding sites of MGT proteins in both species. The prediction of post-translation modifications revealed that MSR2 proteins have high phosphorylation potential than other sub-classes in both studied plants. The expression profile of MGTs showed that MGTs are more expressed in root tissues. In addition, MGTs showed differential expression in response to abiotic/biotic stresses as well as hormone application and NIPAs were more induced in response to stimuli in watermelon. The results of this study, as the primary work of MGT gene family, can be used in programs related to cucurbitaceae breeding.

Within microeukaryotes, genetic and functional variation sometimes accumulate more quickly than morphological differences. To understand the evolutionary history and ecology of such lineages, it is key to examine diversity at multiple levels of organization. In the dinoflagellate family Symbiodiniaceae, which can form endosymbioses with cnidarians (e.g., corals, octocorals, sea anemones, jellies), other marine invertebrates (e.g., sponges, molluscs, flatworms), and protists (e.g., foraminifera), molecular data have been used extensively over the past three decades to describe phenotypes and to make evolutionary and ecological inferences. Despite advances in Symbiodiniaceae genomics, a lack of consensus among researchers with respect to interpreting genetic data has slowed progress in the field and acted as a barrier to reconciling observations. Here, we identify key challenges regarding the assessment and interpretation of Symbiodiniaceae genetic diversity across three levels: species, populations, and communities. We summarize areas of agreement and highlight techniques and approaches that are broadly accepted. In areas where debate remains, we identify unresolved issues and discuss technologies and approaches that can help to fill knowledge gaps related to genetic and phenotypic diversity. We also discuss ways to stimulate progress, in particular by fostering a more inclusive and collaborative research community. We hope that this perspective will inspire and accelerate coral reef science by serving as a resource to those designing experiments, publishing research, and applying for funding related to Symbiodiniaceae and their symbiotic partnerships.
Photo-thermal Tuning of Graphene Oxide Coated Integrated Optical Waveguides
Authors: Moss David
Published: June 2022

We experimentally investigate power-sensitive photo-thermal tuning (PTT) of two-dimensional (2D) graphene oxide (GO) films coated on integrated optical waveguides. We measure the light power thresholds for reversible and permanent GO reduction in silicon nitride (SiN) waveguides integrated with 1 and 2 layers of GO. Raman spectra at different positions of a hybrid waveguide with permanently reduced GO are characterized, verifying the inhomogeneous GO reduction along the direction of light propagation through the waveguide. The differences between the PTT induced by a continuous-wave laser and a pulsed laser are also compared, confirming that the PTT mainly depend on the average input power. These results reveal interesting features for 2D GO films coated on integrated optical waveguides, which are of fundamental importance for the control and engineering of GO’s properties in hybrid integrated photonic devices.

➢ The economics of transitioning total joint arthroplasty (TJA) to standalone ambulatory surgery centers (ASCs) should not be capitalized on at the expense of patient safety in the absence of established superior patient outcomes.

➢ Proper patient selection is essential to maximizing safety and avoiding complications resulting in readmission.

➢ Ambulatory TJA programs should focus on reducing complications frequently associated with delays in discharge.

➢ The transition from hospital-based TJA to ASC-based TJA has substantial financial implications for the hospital, payer, patient, and surgeon.
Mechanism and Prevention of Rockburst in Deep Multipillar Gob-Side Entry
Authors: Pan Junfeng , Du Taotao , Gao Jiaming , Xie Fei
Published: June 2022

Rockburst frequently occurs in deep multipillar gob-side entry in Inner Mongolia and Shaanxi, China. A case study of the Hongqinghe coal mine was analyzed to reveal the occurrence mechanism of rockburst in deep multipillar gob-side entry through theoretical and applied research. And new control methods were put forward. The results show that there is an essential difference between the surrounding rock load characteristics of multipillar gob-side entry and single-pillar gob-side entry. Within the influence area of the lateral goaf, more coal pillars will promote stress concentration, and the high stress concentration area will migrate to the coal pillar of mining roadway. The hanging roof of the working face can cause the stress concentration in the area of leading coal pillar to reach 5 times. The multipillar gob-side entry is less affected by the dynamic load of the roof of the lateral goaf. The ‘F-shaped and L-shaped’ stress source structure model of the deep gob-side multipillar entry was established, and the occurrence mechanism of rockburst is revealed. On the one hand, the static load of rockburst start foundation is formed under the superposition of lateral goaf, rear goaf, and multicoal pillar. On the other hand, the superposition of the foundation static load and the opportune static load induces the start of rockburst. Aiming at the two types of load sources, the fracturing method of kilometer bedding drilling in the roof of coal pillar area is proposed to reduce the foundation static load. The treatment method of periodic tendency blasting fracture of leading roadway roof in a working face reduces opportune static load. The field test has been carried out, and the effect was good.

Análisis de la gestión de redes sociales del gobierno peruano y sus 19 ministerios durante la pandemia del Covid 19
Authors:   , Gonzalez Hernandez Graciela Alicia Fernanda
Published: June 2022

La gestión de los gobiernos de todo el mundo ante la pandemia por la COVID-19 ha colocado en la agenda la importancia de la información y gestión gubernamental, con el fin de brindar a los ciudadanos mensajes que otorguen certezas y calma en contextos de crisis. La gestión comunicativa se ha centrado principalmente en los entornos virtuales, sobre todo en las redes sociales digitales. Esta investigación analiza la gestión de las páginas de Facebook del gobierno del Perú (19 ministerios y la página del propio gobierno) durante la primera ola de la pandemia (marzo—setiembre) a través de un estudio observatorio—descriptiva, con enfoque mixto, centrado en revisar 5837 publicaciones de las cuentas mencionadas. Los hallazgos principales muestran que las páginas estudiadas tienen tendencias disimiles entre ellas, de manera que al ser estudiadas por subgrupos se notan asociaciones respecto de la cantidad de publicaciones, los contextos políticos y sociales de ese periodo, así como las reacciones del público (comentarios o críticas al gobierno). Se concluye que la gestión de comunicación del gobierno peruano mediante Facebook se centró en entender a los públicos como clientes y aliados, y muy poco como ciudadanos que podían invitarlos a ser parte de las acciones sociales.
Reutilización de residuos de construcción y demolición para la fabricación de concreto reciclado a utilizar en columnas
Authors:   , Mateo Rojas Luis Gustavo
Published: June 2022

Uno de los materiales más comunes en los residuos de construcción y demolición, son los residuos de concreto que pueden ser utilizados como agregados gruesos reciclados (AGR) en la elaboración de nuevos materiales de construcción. Debido a esto, el objetivo de este artículo es la incorporación de estos residuos para la fabricación de concreto estrucutral en sustitución del agregado grueso natural (AGN) en porcentajes de 40%, 60% y 80% del volumen de agregados gruesos. Para ello, se evaluó la resistencia a la compresión de las probetas de acuerdo a la norma E.060 “Concreto Armado” del reglamento nacional de edificaciones del Perú y el curado a los 28 días utilizando como guía la norma internacional ASTM C192 “Preparación y curado de mezclas de concreto en laboratorio”, de 3 tipos de mezcla de concreto. Los valores alcanzados muestran una relación indirectamente proporcional entre la resistencia a la compresión y el volumen de RCD en la mezcla, imposibilitando su uso para fines estructurales. Sin embargo, la resistencia obtenida demuestra la viabilidad del uso de RCD para la fabricación de concreto simple y uso en muros, pedestales, y zapatas. Adicionalmente se debe resaltar los beneficios ambientales de la reutilización de estos residuos.

Youth-Led Participatory Action Research Guides
Authors: Million Flore
Published: June 2022

Participatory research challenges the academic tradition in which the scientist is at the center of decisions in the research process. Inspired by popular education, this approach allows members of the community to question their living conditions and develop solutions to improve them from a social justice perspective. These guides were developed and tested as part of two participatory action research projects carried out by Oxfam-Québec with young people (18–30 years old). The two guides provide the key steps to carry out research, build a questionnaire, develop a collective action plan and measure the impacts of the actions implemented.
An Investigation into the Mathematical and Physical Origins of the Fine-Structure Constant
Authors: Williams Lamont
Published: June 2022

The fine-structure constant, α, unites fundamental aspects of electromagnetism, relativity, and quantum physics. As such, it is one of the most important constants in nature. However, why it has the value of approximately 1/137 has been a mystery since it was first identified more than 100 years ago. This study explores the possibility that the value of α is linked to the spacetime geometry of the electromagnetic field between two elementary charges, connecting the smooth manifold responsible for gravity with the discreteness of the electromagnetic field. In a step-by-step manner, the study presents a logical basis for the establishment of a particular equation for α, connecting concepts from general relativity and the Standard Model, and data from experiments to measure the value of elementary electric charge. It is shown how the equation and the model upon which it is built can help explain the Landau pole in such a way that avoids the substantial problem the pole creates in quantum electrodynamics.
Investigating a Self-Management Strategy for Symptoms of Attention-Deficit Hyperactive Disorder and Drug Use.
Authors: Connolly Ross D. , Hesson Jacqueline
Published: June 2022

Introduction: The purpose of the present research was to examine the mediating effect that self-management has on the relationships between ADHD symptoms and nicotine dependence,alcohol use, and drug use among an undergraduate student population.Method: Data were drawn from undergraduate psychology students (N=141). We tested self-management as a mediator between (1) ADHD symptoms and nicotine use, (2) ADHD symptoms and alcohol use, and (3) ADHD symptoms and drug use.Results: Self-management was a significant mediator between ADHD symptoms and drug use, but not nicotine dependence or alcohol use.Conclusion: Self-management was a significant mediator between ADHD symptoms and drug use, which suggests that self-management may play a role in the relationship between ADHD symptoms and drug use. Individuals who have symptoms associated withADHD and who also have high levels of self-management are less likely to use drugs.
