Medan City as the capital city of North Sumatra Province has experienced a fairly rapid developmentÂ in recent years. Various development sectors grow and develop along with increasing economicÂ growth. The housing, services and trade sector is a significant sector of progress. This has resulted inÂ increased intensity and expansion of land use in urban areas. The cause of the flood problem in MedanÂ City is not only absolutely in the downstream of the river, but also in the upstream and middle of theÂ river. The more critical the water catchment area in the Deli river, which is the main watershed thatÂ flows in Medan City, where it is estimated that the good condition of the land currently only rangesÂ from 3-4%, causing the flow of the flow to be greater in the downstream. Thus the management andÂ control of the flood in Medan needs to be taken into account with regard to the topographicÂ conditions.

Published: October 2021

Penetapan daerah tangkapan air merupakan salah satu bagian dari upaya konservasi pada suatu DAS yang penting untuk menjaga keseimbangan air tanah dan air permukaan. Salah satu metode penetapan daerah tangkapan air adalah dengan menggunakan data spasial karakteristik DAS (tata guna lahan, curah hujan dan kemiringan lahan). Faktor karakteristik DAS tersebut diberikan bobot prioritas dengan berbagai pendekatan, salah satunya dengan metode AHP. Metode AHP telah banyak dikembangkan dan memberikan hasil yang cukup baik dalam pemodelan sumber daya air. Penelitian ini menggunakan Sub DAS Cisadane hulu sebagai lokasi penelitian karena memiliki karakteristik DAS yang bervariasi. Dari analisis dengan metode AHP, diperoleh faktor kemiringan memiliki bobot prioritas lebih besar dari faktor tata guna lahan dan curah hujan. Daerah tangkapan air yang dihasilkan pada Cisadane hulu didominasi oleh daerah tangkapan air rendah-sedang.

Pengaruh Penambahan Ekstrak Andaliman terhadap Masa Simpan Nugget Tempe
Authors: Daniela Connie
Published: October 2021

AndalimanÂ  isÂ  typical spice plant in North Sumatra, has benefits as antimicrobial and antioxidant. Tempeh is a protein source food, has short shelf life, so the tempeh processing technology is needed to create another product withÂ  longer shelf life and increase its added value. One of them is by processing tempeh into nugget. The purpose of this study was to determine the shelf life of tempeh nugget added with andaliman fruit extract asÂ  natural preservative and to determine which concentration was the most optimal in extending the shelf life of tempeh nugget. This study usedÂ  completely randomized design with two factors. Factor I was the concentration of andaliman extract (0%, 0.1%, 0.25%, 0.5%) and factor II was the storage time (0 day, 7 days, 14 days, 21 days). The parameters analyzed were total microbial, water content, and aroma organoleptic test. The results showed that the addition of 0.5% andaliman extract and 21 days storage time obtained the lowest amount of microbes, the lowest water content was obtained at 0% andaliman extract and 21 days storage time treatment, while the highest aroma organoleptic test was obtained at adding 0.5% andaliman extracts. This is due to the presence of antimicrobial in andaliman

Published: October 2021

Crop-weather based relation and other aspects of aerial blight incited by Rhizoctoniasolani Kuhn were investigated on two mega varieties (JS 335 and JS 97-52, now susceptible) under central Indian conditions during 2017, 2018 and 2019. It was found that aerial severity and sclerotial formation on affected leaves were varied significantly in all three season, and progress of disease was rapid between 63–84 days old crop {full pod (R4) to maturity initiation (R7) stage}.Increasing crop age was also significantly positively correlated with increasing severity (0.732*) and sclerotial formation (0.981**). Mean relative humidity and maximum temperature of current as well as previous week were found to be positively and negatively correlated with increasing severity of aerial blight, respectively. A regression based model with three explanatory variables (Mean RH, Rainfall and Minimum temperature) of current week was found to be most significant in prediction of disease severity (R2=0.946) of aerial blight. Whereas previous week weather variables i.e. rainy days and rainfall were also accounted 71.7 per cent variability (R2 = 0.717) in disease severity. Overall, weekly average maximum temp (27 to 30o C) and mean RH (80 to 90 per cent) in current week coupled with more rainfall and rainy days in previous week were found to be most conducive field condition for rapid progress of aerial blight disease in soybean.

Published: October 2021

District level rice yield forecast models were developed for 13 districts of the Brahmaputra valley of Assam using yield data and weekly weather data during 1990-2012 at vegetative (F1) and mid-season (F2) stages of rice crop through modified Hendrick and Scholl technique. The models were validated using independent data set of three years (2013-15). Stepwise regression technique was used for fitting the model and decided best by highest R2 and lowest percent error. The coefficient of determination (R2) ranged from 0.32 (Jorhat) to 0.88 (Kamrup) in F1 stage and 0.29 (Sonitpur) to 0.92 (Kamrup) in F2 forecast. In general, F2 forecast models were found comparatively better in forecasting rice yields than F1 models. Inclusion of BSSH along with temperature (maximum and minimum), rainfall and relative humidity (morning and afternoon) increased the accuracy of the yield forecast models, compared to the model developed without BSSH. Maximum temperature and relative humidity were the major weather parameters in determining rice yields in most of the districts located in central and upper part of the valley. On the other hand, rainfall in combination with maximum temperature and relative humidity were found relatively more important in the districts located in the lower part of the Brahmaputra valley.

Published: October 2021

In Latvia to perform COVID-19 tests as well as for temporary shelters in case of a local disease outbreak the persons were located in special tents. Such practice was not only performed locally but also in other countries like the USA, UK, Russia, etc. The wide usage of tents was possible as the outbreak happened during the warm period of the year. At the same time, the indoor climate of tents can be quite unbearable during the warm summer days. Also, the situation was not getting better as fast as the prognosis, and the crisis was still ongoing during the winter period. Therefore, to test the thermal comfort of such temporary shelter’s measurements were performed. The thermal comfort was measured in a tent from 27th May to 28th September 2020. The data was logged with three different measuring devices inside of the shelter as well as outside air parameters like temperature and solar radiation was logged. The results show the rapidly changing indoor temperature which reaches 40°C during the daytime and falls to 10°C at night. The data of the globe thermometer to analyze the influence of radiation from tent canvas was also studied and showed that there is no noticeable heat radiation from external walls. The PMV measurements showed that the thermal comfort is very low as the PMV values were outside the range of -1 to 1 for 57% of the time. The influence of the precipitation was also noted, and the results showed that the adiabatic cooling effect is very variable but in general does not noticeably change the indoor temperature, the average temperature decrease was only 1 °C, but for a specific case it reached 10°C.
Influence of Image Enhancement Techniques on Effectiveness of Unconstrained Face Detection and Identification
Authors: Vukovic Igor , Cisar Petar , Kuk Kristijan , Bandjur Milos , Popovic Brankica
Published: October 2021

In a criminal investigation, along with processing forensic evidence, different investigative techniques are used to identify the perpetrator of the crime. It includes collecting and analyzing unconstrained face images, mostly with low resolution and various qualities, making identification difficult. Since police organizations have limited resources, in this paper, we propose a novel method that utilizes off-the-shelf solutions (Dlib library Histogram of Oriented Gradients-HOG face detectors and the ResNet faces feature vector extractor) to provide practical assistance in unconstrained face identification. Our experiment aimed to establish which one (if any) of the basic image enhancement techniques should be applied to increase the effectiveness. Results obtained from three publicly available databases and one created for this research (simulating police investigators’ database) showed that resizing the image (especially with a resolution lower than 150 pixels) should always precede enhancement to improve face detection accuracy. The best results in determining whether they are the same or different persons in images were obtained by applying sharpening with a high-pass filter, whereas normalization gives the highest classification scores when a single weight value is applied to data from all four databases.
Viele Stimmen – ein Urteil
Authors: Bletsas Marina
Published: October 2021

Modern jurisprudence is intrinsically pervaded by a plurality of intertwined voices, only part of which can be traced back to the Court of Justice deciding the case. This book sheds light on the rhetorical-argumentative function of this linguistic polyphony by using the example of the Italian Constitutional Court judgement. To this end, an integrated polyphonic-argumentative approach is proposed on the basis of the Scandinavian polyphony and pragmadialectical theory of argumentation. With the help of the theoretical and methodological apparatus thus developed, the study shows how the reasons for the Italian constitutional court's decision can be understood and reconstructed as a literally staged argumentative discussion.
Hass
Authors: Fischer Jeannette
Published: October 2021

Jeannette Fischer examines what it is that leads to hate and to hateful actions. Hatred against others begins as self-hatred. This in turn has its cause in feelings of guilt that were already triggered in us in childhood. To illustrate this, the author uses examples like the horrific rampage of Anders Breivik in 2011 and the decision of a young Canadian to join the IS. The victim/perpetrator and guilt/innocence narrative is a dominant pattern in our actions and discourses; we are held prisoners by it. And it shows up not only at the personal level, but also in social and political interactions. We cannot eliminate hate by condemning it, abhorring it, even hating it. Change is brought about only by leaving the vicious circle and making clear what leads to its creation.
Experimental Setup for Swellable Elastomers in Cased and Open Holes
Authors: Zahid Qamar Sayyad , Akhtar Maaz , Pervez Tasneem
Published: October 2021

A full scale experimental setup was designed and commissioned for testing of swelling elastomer seals against a casing (cased hole) and formation (open hole). Actual replicate of wellbore was designed with varying inside diameters and roughness to reproduce the effect of actual formation. The Dynaset packer mounted on a 7-inch tubular was allowed to swell against a 9–5/8-inch casing, while the fast swell packer mounted on a 9–5/8-inch tubular was allowed to swell against the 12–1/4-inch replicated well bore. This one-of-its-kind test setup can demonstrate the way the elastomers swell out and fill the asperities against smooth outer casing (cased hole) or against rough wellbore surface (open hole). Dismantling of the test setup midway through the testing scheme revealed a severely dimpled surface of the swelled elastomer.
Mechanical and Structural Behavior of Swelling Elastomers under Compressive Loading
Authors: Zahid Qamar Sayyad , Akhtar Maaz , Pervez Tasneem
Published: October 2021

Swelling elastomers are a new breed of advanced polymers, and found increasing use in drilling of difficult oil and gas wells. It is important to know how an elastomer will behave under a given set of well conditions, especially after the initial quick-swell period. Good design depends on appropriate material selection. Results are presented in this chapter from experimental and numerical studies conducted to analyze how compressive and bulk behavior of actual oilfield elastomers changes due to swelling. Six key attributes of swelling elastomers needed for design improvement and performance analysis of elastomer seals are discussed: four mechanical properties (elastic modulus E, bulk modulus K, shear modulus G, and Poisson’s ratio ν), and two polymer structure characteristics (cross-link chain density NC, and average molecular weight MC). These parameters were experimentally determined before and after various stages of swelling for two different swelling elastomers being currently used by the regional petroleum industry, in low and high salinity brines. To strengthen the experimental results, and to be able to forecast for other elastomer materials and well conditions, tests were also simulated using the commercial FEM package ABAQUS, using the best available hyperelastic material models.
Numerical Investigation of Elastomer Seal Performance
Authors: Zahid Qamar Sayyad , Akhtar Maaz , Pervez Tasneem
Published: October 2021

Analytical models for swelling of rubberlike materials are difficult to formulate, and restricted in actual application due to their need for simplifying assumptions. Tests conducted on laboratory size samples of swelling elastomers cannot reproduce actual oil well conditions, and cannot cover all possible variations of testing parameters. However, these laboratory tests do provide useful information about material response of swellable elastomers in various conditions, serving as a basis for analytical and numerical modeling. Properly developed and robust numerical models can be used to predict near-actual performance of elastomeric seals. The current chapter describes the use of numerical (finite element) simulation to investigate swelling elastomer seal behavior in downhole petroleum applications. Variations in sealing (contact) pressure are studied for seal length, seal thickness, compression ratio, water salinity, swelling time, and type of well completion (open-hole or cased-hole). Month-long swelling experiments on samples of two actual elastomers (Chapters 3 and 7) provide input to the numerical model in terms of real material and deformation data. On the basis of these results, petroleum engineers can make informed decisions about the selection of elastomer material and seal geometry appropriate for the well type and conditions encountered. Application developers and researchers can also find this investigation useful in performance analysis and design of swelling elastomer seals.
Rich Ornaments and Delightful Engines: The Poetics of Failed Festivity and Figural Automation in William Shakespeare’s Titus Andronicus
Authors: Żukowska Agnieszka
Published: October 2021

The present study focuses on the poetics of failed festivity in William Shakespeare’s Titus Andronicus, tracing analogies between early modern festival culture, in particular the Joyous Entry of the Renaissance prince into the city, and the machinery of the play, which is set in motion by Titus. The principal element of this machinery is the figure of Lavinia, who can be seen as the inverted version of such wonders of occa- sional architecture and civic pageantry as the automaton, the breathing sculpture and the automatic waterwork. One of the major problems explored is the confrontation of reality and fiction, or human flesh and art, in the manifestly echoic universe of the play, where the objectified automaton-like figure responds to the actions of its animators with its own stirring.
Living through Precarity: A Butlerian Study of Jhumpa Lahiri’s The Lowland
Authors: Farahbakhsh Alireza , Hoseini Peyman
Published: October 2021

This article aims to explore Judith Butler’s concept of precarity in Jhumpa Lahiri’s The Lowland. The questions this study seeks to find answers to are: What are the various manifestations of Butler’s notion of precarity in The Lowland? And to what extent does the Butlerian sense of agency allow the main characters of The Lowland the possi- bility of overcoming precarity? This research shows how enforced dispossession, which is a product of globally-imposed precarity, incites violence and leads to the involuntary migration of the subjects. In addition, it is revealed that precarity plays a segregative role in escalating religious and tribal conflicts in the post-Partition India. More importantly, in the final analysis, this study suggests that Butler’s reiterative sense of agency fails to account for the normative dynamics of precarity which is at work in the diasporic context of The Lowland.
Sex, Dr(a)gs and Rock’n’Roll: Diverse Masculinities of Glam Metal, Sleaze Metal and Hair Metal
Authors: Jeray Celina
Published: October 2021

The following essay retraces the genre development and correlations of three 1980s hard rock subgenres: glam metal, sleaze metal and hair metal. This issue is consid- ered, primarily, with reference to the theory of hegemonic and non-hegemonic masculini- ties developed by Raewyn Connell and reviewed against the theory of genre development by Jennifer C. Lena and Richard A. Peterson. Both theories are employed in order to un- derline the subtle differences between the subgenres, arguably linked to the masculinities performed by the artists’ assumed stage personas. Aside from the scholarly references, the research includes various interviews with the artists and music journalists, an analysis of over a hundred song lyrics and the vast repertoire of visual arts accompanying the music.
Lexical Bundles Ending in that in Academic Writing by Czech Learners and Native Speakers of English
Authors: Brůhová Gabriela , Vašků Kateřina
Published: October 2021

The aim of this paper is to explore how Czech learners of English use lexical bundles ending in that in their academic texts in comparison with novice and professional L1 authors. The analysis is based on three corpora (VESPA-CZ, BAWE and our own cor- pus of papers published in academic journals). The results suggest that Czech learners of English do not use a more limited repertoire of lexical bundles ending in that than pro- fessional writers. However, there are differences between the groups studied, especially in the range of various shell nouns used in nominal bundles. Novice writers, both L1 and L2, use bundles ending in that to express stance more frequently than professional writers.
Application of intuitionistic fuzzy sets to environmental management
Authors:   Department of Mathematics, Federal University Dutse, Adamu I. M.
Published: October 2021

Environmental management is a decision making problem with a great deal of uncertainties. Intuitionistic fuzzy sets provide a model to elaborate these uncertainties and vagueness involve in decision making. This paper, proposes an application of intuitionistic fuzzy set to environmental management in order to determine the type of erosion(s) affecting some towns for an effective control measure that has to be taken using a distance function. In order to achieve this, a set of erosions and their causes are assumed, and also we assume a survey for the set of towns to determine the type of erosion approaching them for an effective control measure to be taken.

How does the human brain encode semantic information about objects? This paper reconciles two seemingly contradictory views. The first proposes that local neural populations independently encode semantic features; the second, that semantic representations arise as a dynamic distributed code that changes radically with stimulus processing. Combining simulations with a well-known neural network model of semantic memory, multivariate pattern classification, and human electrocorticography, we find that both views are partially correct: information about the animacy of a depicted stimulus is distributed across ventral temporal cortex in a dynamic code possessing feature-like elements posteriorly but with elements that change rapidly and nonlinearly in anterior regions. This pattern is consistent with the view that anterior temporal lobes serve as a deep cross-modal ‘hub’ in an interactive semantic network, and more generally suggests that tertiary association cortices may adopt dynamic distributed codes difficult to detect with common brain imaging methods.
New Theoretical Model of Electric Arc in Circuit Breaker and the Role of Parallel Resistance – The Shunt
Authors: Bjelić S. , Marković N. , Jakšić U. , Marković F.
Published: October 2021

Aims: The paper presents a new theoretical model of an electric arc in a circuit breaker with reference to the role of shunt resistance parallel to the electric arc in a circuit breaker switch. One of the goals of the paper is to show the efficiency of using the software package MATLAB Simulink in which the previously derived system of equations is easily implemented in the blocks of the mentioned software package.

Methodology: The discharges in the electric arc determine the potential between the metal contacts of the switch and the structure and shape of the electric arc make it difficult to solve the transient process. The main step in solving the problem is the formation of a theoretical model of the electric circuit from which the current and voltage can be determined, which depend on the parameters of the electric field in the arc. The use of shunts in oil and air switches, due to a number of shortcomings, was not possible, but the disadvantages are overcome if thyristors are used to interrupt the current. The equations and the algorithm for solving the problem are obtained from the parameters of the electric field potential that shape the electric arc and its path. The accuracy of the theoretical model is confirmed by voltage and current diagrams in the adapted MATLAB Simulink software package.

Conclusion: The presented theoretical model and algorithm are universal and can be used for different states in which an electric line can be found. Problems that occur in the analysis of transient processes in an electric circuit where an electric arc occurs can be minimized using different types of simulations. Changing any parameter in the electrical circuit requires a new calculation of the state of the circuit from the very beginning due to the new initial conditions. Analytical methods combined with the simulation method were used in the research of overvoltages, asymmetries and harmonics during the appearance of an electric arc. The MATLAB simulation program had a threefold purpose: to serve the calculation and simulation of quantities that can be obtained by testing or measurement, to establish the original algorithm and to verify the proposed method. Also, this type of simulation can replace the type tests of the electric arc on the switch.

Zenherb labs Pvt. Ltd., Mumbai, developed a proprietary Arctostaphylous uva-ursi standardized extract (AUSE), (branded as UvaZen-VArb™). The current study is an attempt to get insights of the interaction of bioactives against target proteins involved in skin health pathways like melanogenesis.  A molecular docking approach was adopted to understand the protein-ligand interactions and predict the most probable mechanism(s) of beneficial skin health effects imparted by this cosmeceutical ingredient. Four phytoconstituents were docked against 15 shortlisted target proteins using Autodock Vina tool. Drug likeliness was assessed on the basis of ADMET properties and Lipinski’s Rule of 5. Arbutin, gallic acid, quercetin and rutin in AUSE demonstrated good docking scores and bioactivities for melanin regulation, cell growth, proliferation and differentiation-hair, skin and nail.
A sexualidade velada da mulher vitoriana: análise da obra literária Carmilla, de Le Fanu
Authors: Souza Sweder , Souza Tatiana
Published: October 2021

O presente trabalho pretende analisar o discurso acerca da sexualidade velada da mulher vitoriana no final do século XIX, utilizando a obra literária Carmilla: a vampira de Karnstein escrita pelo pai da Literatura Fantástica, Sheridan Le Fanu, em 1872. A era vitoriana é uma sociedade patriarcal que tem como base a família, da qual a mulher é a representante e responsável por essa base familiar. Sua imagem é representada de forma angelical e meiga, o anjo do lar, uma mulher sem desejos, totalmente reprimida sexualmente pela sociedade patriarcal e objeto do homem. Carmilla representa a libertação dessa mulher, rompendo com os padrões sociais do período, ela é a representação da mulher Femme Fatale, mulher que sente desejo sexual, dominadora, sedutora e dona de si. Mulher temida pelo sexo masculino, pois age através do instinto, motivo de perigo para a sociedade vitoriana. A vampira é tudo aquilo que a mulher vitoriana desejava ser e sentir, Carmilla é a libertação desta mulher.
(Des)patologizar é (des)diagnosticar? Inquietações sobre as disputas por autonomia no campo político
Authors: Favero Sofia Ricardo , Souza Fernanda Hermínia
Published: October 2021

O objetivo deste trabalho é analisar as estratégias pela despatologização das identidades trans e travestis, por meio de documentos, portarias, resoluções, notas técnicas e manuais responsáveis por regular o exercício de profissionais de saúde mental envolvidos com essa população. Para tanto, destaca o papel do diagnóstico frente a essas mobilizações que pretendem, por um lado, suspender os efeitos estigmatizantes da patologização, mas que, por outro lado, aparentam defender a possibilidade de avaliar clinicamente o gênero de um paciente. Em conclusão, propõe que as lutas pela despatologização precisam estar alinhadas a um combate à produção diagnóstica.
Alianças monstruosas e desejantes contra o sequestro da política pela esfera estatal
Authors: Troi Marcelo de
Published: October 2021

A partir de resultados da pesquisa de mestrado intitulada Corpo dissidente e desaprendizagem: do Teat(r)o Oficina aos a(r)tivismos queer, o artigo avança nas questões que envolvem representação, arte e ativismo para pensar outras formas de política e regimes de alianças ante a radicalização do campo da extrema direita no Brasil. Com base nas teorias pós-humanas, o texto localiza o corpo dissidente como abertura para alianças monstruosas e desejantes, mais próximas ao paradigma multinaturalista e de uma política que busque novos parentescos, com forte adesão ao campo imanente e ao desenvolvimento de práticas territoriais.

O presente trabalho pretende apresentar minimamente o conceito-prática de representação política tentando demonstra a relação intrínseca com as categorias de sujeito, política, ontologia, cultura e sexualidade partindo do pensamento de Judith Butler em três textos: Sujeito do sexo/gênero/desejo, Tortura e a ética da fotografia: pensando com Sontag e a Introdução do livro A vida psíquica do poder.
Alianzas y agencias políticas de la disidencia sexual y de género: ¿Una forma para sobrevivir en El Salvador?
Authors: Arévalo Amaral , Solorzano Andre
Published: October 2021

El Salvador convive con una epidemia crónica de violencia, en ese contexto el Estado Salvadoreño no ha sido capaz de brindarle a su población de Lesbianas, Gay, Bisexuales, población Trans, Intersexuales y otras identidades sexuales y de género (LGBTI+), las garantías legales y civiles para que puedan ejercer sus plenas facultades, tener una vida plena, digna y en un ámbito de seguridad. Las organizaciones LGBTI+ en la década de 2010 realizaron una incidencia política a diversos niveles del Estado. Este artículo busca analizar los procesos de y Agencias políticas como estrategias de sobrevivencia, resistencia y humanización de la población de LGBTI+ ante el contexto de violencia epidémica y crónica que padece El Salvador. Como resultado obtenemos que los procesos de alianzas y agencias política se han enfocado en la promoción de reconocimiento institucional y social de las personas LGBTI+. Los procesos de reconocimiento han sido limitados y precarios, debido a que éstos se han asumido como una política personalizada y no institucional mostrando la fragilidad del Estado y el trato de desigualdad en una población históricamente excluida de las políticas públicas.
O cinema como criador de próteses: uma análise díldica de Os rapazes das calçadas
Authors: Stumm Eugênio Helyantus , Weinmann Amadeu De Oliveira
Published: October 2021

Os anos da ditadura militar brasileira de 1964-1985 foram marcados, nas produções audiovisuais, por uma forte representação abjeta e cisheteronormativa das multidões sexopolíticas. Nossa premissa é a existência de linhas de fuga, em tais lógicas. Nos aproximamos de gêneros fílmicos produzidos na época – mais especificamente, a pornochanchada e a pornografia explícita –, para investigar tais questões. Elencamos, para a construção desta análise, a película Os rapazes das calçadas, lançada em 1981. Operamos a análise fílmica em diálogo com a interpretação do sonho, na psicanálise; mais precisamente, com a articulação entre trabalho do sonho e trabalho do filme, proposta por Thierry Kuntzel. Além disso, entendemos, em sintonia com Preciado, que o cinema consiste em uma prótese de sonhos. Tais próteses permitem deslocar a coincidência entre carne e corpo, assim como contrassexualizar o prazer narrativo-visual. Tecendo diálogos com as análises fílmicas, a psicanálise e a teoria queer, propomos pensar o cinema, além de prótese de sonho, sobretudo como criador de próteses. Nesse sentido, também propomos o deslocamento da análise fílmica, aqui, para o que chamamos de análise díldica, isto é, a prótese-dildo entendida a partir do cinema.
Performances trans incomodam? Quando a vida em público é passível de violência
Authors: Souza Daniela
Published: October 2021

Neste texto nos dedicamos às performatividades discursivas midiáticas que narram as lutas de corpos marginalizados, excluídos e desumanizados. Nos atemos à novela “A Força do Querer”, da Rede Globo de Televisão, enquanto produção midiática que impulsiona a circulação de discursos sobre a transexualidade. O ângulo de observação pretendido contempla semioses direcionadas a situações de violência e performatividades de afeto decorrentes de tais situações. Através de índices que entremeiam significações de violência pretendemos observar como a precariedade está entextualizada. Os afetos, neste caso, são significativos do reconhecimento da humanidade presente nestas vidas, de modo que através deles é possível observar se essas vidas são consideradas vivíveis ou visíveis. São perguntas a serem respondidas aqui: De que forma a transfobia é entextualizada? Quais discursos são utilizados para justificar, motivar ou endossar atos de violência?  Quais afetos são levados em conta?  As noções de vergonha, medo, melancolia, solidão e trauma estão envolvidas?  São conceitos operacionalizantes da análise de texto aplicados a este trabalho: entextualização e indexicalidade. Precariedade, violência, reconhecimento, afeto, soberania e estado de exceção são temas transdisciplinares que nortearam também este texto. A visibilidade midiática da violência contra o corpo trans confere a este subgrupo de vidas, marginalizado pelo biopoder, o reconhecimento da precariedade. A vida em si é representativa de um coletivo numérico que morre todos dias, que é assediada, violentada, ferida, desumanizada. O afeto, neste caso, torna o corpo trans reconhecível, dá vida a este corpo, humaniza-o, torna-o enlutado. Os afetos tornam dicotomicamente reconhecíveis tanto a precariedade, violência e morte quanto a vida vivível.
Ressonâncias nietzscheanas e o manifesto por uma grande saúde: educações sexuais para além da doença
Authors: Polizel Alexandre Luiz , Oliveira Moises Alves de
Published: October 2021

Este manuscrito tem por objetivo pensar os armamentos às educações para as sexualidades para além da doença, voltada a grande saúde. Para isto este ensaio teórico inclina-se aos estudos de Friedrich Nietzsche, que tece ataques a educações do seu tempo, voltada a produções de valores que endurecem os pensamentos, bem como os modos de ser, estar e existir. A este endurecimento de saberes, característicos da episteme ocidental, que adoece a existência, Nietzsche trata como uma doença. A educação da modernidade assim contribui para a disseminação desta doença, guiando a vontade dos aprendizes aos arrebanhamentos, submetendo sua existência a domestificação, o que reverbera nas educações para as sexualidades e formatações dos corpos. Todavia, é possível uma educação outra, uma educação voltada a grande saúde. Assim, o presente trabalho traça considerações acerca: a) do endurecimento do pensamento: as doenças; b) as relações entre o dispositivo pedagógico, a moralidade e o arrebanhamento; e c) as educações para as sexualidades em uma grande saúde.
