Evaluación ergonómica en trabajos de construcción en el sureste de México
Authors: Solís Carcaño Rómel , Zavala Barrera Daniel , Audeves Pérez Selene Aimée
Published: July 2023

Los problemas asociados a las condiciones ergonómicas inadecuadas en el trabajo están adquiriendo una importancia creciente en la actualidad, por lo que se considera de vital importancia estudiar si los procedimientos habituales utilizados en las actividades de la construcción cumplen con los principios básicos de la ergonomía [1]; especialmente si se considera que, por lo general, se realizan bajo un entorno tecnológico poco tecnificado. Se han identificado que, en las actividades de la construcción, los principales riesgos ergonómicos se relacionan con las posturas forzadas, el manejo manual de cargas y los movimientos repetitivos [1]. El objetivo del presente estudio fue analizar los movimientos realizados y posturas empleadas por los trabajadores de la construcción [1] para determinar los niveles de riesgos ergonómicos con las que son realizadas. Se evaluaron siete actividades y para esto se emplearon tres diferentes métodos de evaluación ergonómica. Como resultado, se obtuvo que los trabajadores de la industria de la construcción están realizando sus tareas bajo niveles de riesgo ergonómico que no deberían ser aceptados. Los riesgos ergonómicos más críticos observados fueron en actividades relacionadas con transporte manual de carga y las posturas forzadas [1].
Die Illusionen der Berlin-brandenburgischen Landesplanung
Authors: V. Einem Eberhard
Published: July 2023

Die vergangenen 3 1/2 Jahre waren (zwar nicht nur, aber auch) in Berlin und Brandenburg „heiße Zeiten“ für Zukunftswerkstätten, Denkfabriken und Kongresse. Wenn man den – mit breiten Filzstiften oder beschwörenden Worten – zu Papier gebrachten Visionen und suggestiven Plänen glauben darf, ist die Berlin-brandenburgische Landesplanung auf dem Reißbrett längst Wirklichkeit: Autofreie Stadt, Polyzentralität, Entlastungsstädte, Regierungsviertel, Bodenfonds, Grünschneisen und Sicherung der Naturpotentiale. Freilich kümmert sich die tatsächlicheEntwicklung wenig um wohlmeinende Ideenkonzepte oder Debatten im Feuilleton. Sie gehorcht ganz anderen Entwicklungsgesetzen: Demographie und Migration, Eigentumsverhältnisse und Mieten, öffentliche Finanzknappheit und Weltmarktkonkurrenz lauten ihre Parameter. Sprich: die Ideen auf dem Papier nehmen sich demgegenüber – ohne Umsetzung in Baurecht und Finanzentscheidungen – oft hilflos aus. Für einen jungfräulich-naiven Glauben an die Gestaltungsspielräume der Landesentwicklung ist kein Raum, wo enge regionalwirtschaftliche, rechtliche und politische Restriktionen den staatlichen Handlungsrahmen einengen.Die Frage lautet deshalb schlicht: Wie realistisch sind die Konzepte? Welche Chancen bestehen – ernsthaft geprüft – sie umzusetzen – selbst bei unterstellter „best practice“? Wie stark engen die nicht steuerbaren Restriktionen gutgemeinte Planungen ein? Auf den folgenden Seiten soll versucht werden, drei in der Planung beliebte Vorstellungen zu hinterfragen und anhand dieser drei Punkte die Illusionen der Landesplanung offenzulegen.
Umweltverträglichkeitsprüfung in Brasilien
Authors: Dilger Robert , Juchem Peno A. , Pereira de Queiroz Sandra M.
Published: July 2023

Brasilien stand schon immer im internationalen Rampenlicht ökologischer Besorgnisse, vor allem, wenn man an die Gefährdung der amazonischen Regenwald-Ökosysteme, an gigantische Staudammbauten oder Großprojekte des Straßenbaus und der Erzgewinnung denkt. Die UNCED-Umweltkonferenz im Juni 1992 lenkte ein weiteres Mal den Blick auf die Umweltverhältnisse in diesem Land, in erfreulicher Differenzierung: Wurde doch wahrgenommen, daß auch und gerade in den Industrie- und Ballungsregionen des Landes die Umweltqualität bereits derart schlecht geworden ist, daß die Lebens- und Produktionsverhältnisse ernsthaft bedroht sind. Die Situation in São Paulo und in der benachbarten Industrieregion im Vale de Cubatão sind nur ein Beispiel dafür.Weniger bekannt dürfte jedoch sein, daß die Umweltgesetzgebung in Brasilien durchaus dem Standard moderner Industrieländer vergleichbar ist und Brasilien dies auch auf der UNCED-Konferenz durch die Unterschriften unter die verschiedenen Dokumente zu Klima, Biodiversität usw. dokumentiert hat.Dieser Beitrag will am Beispiel der Umweltverträglichkeitsprüfung zeigen, wie sich politisches Wollen gesetzgeberische Absicht und verwaltungsmäßige Umsetzung der Vorschriften den Umweltproblemen Brasiliens in der täglichen Praxis stellen. Am Beispiel der paranaensischen Landesumweltbehörde IAP (Instituto Ambiental de Paraná, vormals SUREHMA – Superintendencia dos Recursos Hidricos e Meio Ambiente) werden Grundlagen, Ablaufschema und Probleme bei der Anwendung und Umsetzung der UVP im Planfeststellungsverfahren dargestellt und diskutiert.Dieser Beitrag ist innerhalb eines Projektes der Technischen Zusammenarbeit im Umweltbereich zwischen Brasilien und der Bundesrepublik Deutschland entstanden, die unter dem Titel „Umweltauswirkungen von Staudammvorhaben“ seit 1987 vom bereits erwähnten IAP und der GTZ (Deutsche Gesellschaft für Technische Zusammenarbeit GmbH) im Auftrag des Bundesministeriums für wirtschaftliche Zusammenarbeit durchgeführt wird.

Published: July 2023

In the present study, oxytetracycline (OTC) was selected as a medical contaminant with an organic structure to increase the efficiency and feasibility of comparison with other research studies. Therefore, the removal of OTC from medicinal effluents using different methods; namely, activated carbon, bentonite adsorption, iron(III) chloride coagulation, membrane filtration and reverse osmosis (RO), was investigated. Results indicated that the removal of soluble antibiotics in the factory wastewater by adsorption method was between 35% and 77%, at a pH of 6.5 and the total dissolved solids (TDS) and OTC concentration were reduced by 55% and 77%, respectively. In the coagulation method, where the suitable pH ranges from 5.5 to and 7.5, the optimal dosage of iron (III) chloride coagulation was between 40 and 100 mg/l, which resulted in 98.7% of OTC removal. It was concluded that the highest OTC adsorption of 98.7% in the RO membrane and TDS removal were obtained at a pressure of 9 bars. All the experiments on these membranes were performed within 4 months and the membranes still performed well. Therefore, it is concluded that long-term operation has little effect on the performance of the membrane and this membrane is a suitable membrane for the concentration of OTC. Finally, the RO is defined as the suitable method for OTC removal, after passing once through the membrane, while the other methods are proper to be used in the pre-treatment of medicinal wastewater. KEYWORDS: Antibiotics, Absorption, Coagulation, Membrane filtration, Reverse osmosis.
Effects of Chute Block Geometry on the Performance of the USBR II Stilling Basin
Authors:   Basrah University, Ali Mohammed Saleh Layla , Issa Khassaf Saleh
Published: July 2023

Stilling basins are designed to reduce the high kinetic energy of supercritical flow in a downstream spillway. The USBR II stilling basin is distinguished by chute blocks fixed at the upstream end and a dented sill at the downstream end, allowing for the effective dissipation of excess energy. This research investigates the effect of chute-block geometry on the hydraulic performance of the USBR II stilling basin. Six modified chute-blocks with identical dimensions and spacings as standard blocks were constructed and evaluated for six incoming Froude-number values. The results indicate that chute blocks containing stepped side walls are more effective than standard blocks, increasing energy dissipation by 1.47% and decreasing the sequent depth ratio by 3.91%. Blocks with gradually increased spacings lose 0.7% more energy than standard blocks and reduce the sequential depth ratio by 1.91%. However, blocks with prismatic spacings and top surface angles of 152 degrees, relative to the downstream slope of the spillway, are less effective than standard blocks with energy dissipation reduced by 2.73% and the depth ratio increased by 7.24%.

Authors: Lenart Agnieszka
Published: July 2023

The article deals with the therapeutic aspects of literature. The research material is the prose of Victoria Reicher, a writer who represents the younger generation of Russian-Israeli olim. The author analyses selected works from Yoshka’s house and Telling tales to the left collections. In the texts analyzed, the author sees specific patterns of behavior, typical not only of Russian-speaking repatriates in Israel but also describing the contemporary human, immersed in the chaos of this world. One of the characteristics of Reicher’s prose is carnivalization. The humor and chaos reveal a frank and true picture of everyday life. According to the author, Reicher’s literature has a purifying purpose and contains psychodrama elements. It provokes reflection, stimulates mental and emotional activity, and soothes negative emotions. The author proves that Reicher, a writer, and trained psychologist, can help readers solve their problems – through her texts, blog, and constant presence on the Internet. Reicher’s literature has the characteristics of therapeutic literature. Moreover, it is an affective bibliotherapy, and guided reading.

Authors: Parashar Apoorva , Rishi Rahul , Parashar Anubha , Rida Imad
Published: July 2023

Arthritis is a musculoskeletal disorder. Millions of people have arthritis, making it one of the most common joint disorders. Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most common types of arthritis among the many different types available. Pain, stiffness, and inflammation are among the early signs of arthritis, which can progress to severe immobility at a later stage if left untreated. Although arthritis cannot be cured at any point in time, it can be managed if diagnosed and treated correctly. Clinical diagnostic and medical imaging methods are currently used to evaluate OA and RA, both debilitating conditions. This review is focused on deep learning approaches used by taking medical imaging (X-rays and magnetic resonance imaging) as input for the detection of RA.
“Chemistry, climate and the skills in between”: mapping cognitive skills in an innovative program designed to empower future citizens to address global challenges
Authors: Rap Shelley , Geller Sharon , Katchevich Dvora , Gbarin Hanan , Blonder Ron
Published: July 2023

One of the primary objectives of an education system is to prepare students for their adult lives by imparting them with the requisite knowledge, qualifications, and skills that will enable them to confront future challenges effectively. A whitepaper published by the Israeli Ministry of Education titled “The Graduate’s Image” stresses the importance of incorporating specific skills into the school curriculum. However, there is a lack of educational programs that can transform teaching skills into actual practice. In light of this conclusion, we developed the program “Chemistry, Climate & the Numbers in Between” to foster these skills and produce graduates with the ability to adopt a critical approach and a well-informed perspective toward the world. In this paper, we delineated the cognitive skills developed in the program. The results indicate that innovative program can be utilized to integrate several important skills into a chemistry lesson. The program has the potential to equip and empower future citizens to address and tackle global challenges while utilizing cognitive skills using chemistry knowledge. However, it is important to note that learning in this way requires much more time than a regular lesson does and requires a significant commitment and investment from the teacher.

Published: July 2023

This research focuses on recycling rubber tire waste through pyrolysis to produce recovered carbon black (rCB). The rCB is combined with recycled low-density polyethylene (rLDPE), calcium carbonate (CaCO3), fatty acid, metallic stearate, and polyethylene (PE) wax to create an rCB masterbatch for household packaging. Surface modification of CaCO3 particles using stearic acid improves the compatibility with LDPE. The study investigates mechanical properties, morphology, melt flow index (MFI), X-ray diffraction, and thermogravimetric analysis in three systems: uncoated, coated, and a hybrid combination of coated and uncoated CaCO3 in LDPE/rCB masterbatch composites. The coated system demonstrates higher mechanical properties and improved compatibility between CaCO3 and LDPE. All three systems exhibit enhanced thermal stability and MFI compared to virgin LDPE, with the coated system showing the most significant improvement. The study showcases the potential of LDPE/rCB masterbatch composites for household packaging, with the coated system displaying the optimum performance across various characteristics.
An Ethnographic Study Exploring the Effect of Family on the Development of Entrepreneurial Intentions of Its Younger Members in the Delhi-NCR Region of India
Authors: Gaur Ankit , Robson Paul , Vazquez-Brust Diego
Published: July 2023

The study uses data from an ethnographic study of 32 family members from six families from New Delhi and the National Capital Region (NCR), India, to develop our understanding of entrepreneurial intentions in the younger members of middle-class families of India. The study identifies two critical familial influences, generational congruence and the need to maintain harmony, along with the presence of feministic values, as factors that impact the development of entrepreneurial intentions. The study further confirms that the need to conform to a social image impacts the decisions taken by family members. By highlighting the significant influence that family can have on the development of entrepreneurial intentions, this research points out gaps in how current policies and programs target entrepreneurship development in transforming economies like India. While the limited geographic scope of this study makes the findings applicable only to families in New Delhi and NCR and less generalizable overall, it further highlights the need to conduct similar studies across other parts of India, as well as other countries with similar cultural dimensions as India. The researchers suggest focussing policies towards promoting trust and confidence in entrepreneurship as a potential career option and highlighting the benefits of pursuing entrepreneurship amongst the masses by keeping in mind the cultural and geographic differences across the country. The novelty of this study lies firstly in its methodological approach, where entrepreneurial intentions are evaluated via short ethnographies. Secondly, with a strong focus on Indian family dynamics, the authors have identified novel influences that could apply to other transforming economies with similar social-cultural factors to India.

Published: July 2023

Succinic acid is a valuable organic acid with a high commercial value that may be employed in a variety of sectors including food, cosmetics, and chemistry. Through bacterial fermentation, succinic acid can be easily produced. This paper includes a broad body of literature assessment spanning the previous two decades on the evaluation of succinic acid (SA) production procedures in to further drive research toward membrane-based sustainable and affordable production. The best natural method of SA producer is through Actinobacillus succinogenes. The process of microbial fermentation is used to produce bio-succinic acid utilizing agro-industrial waste. There are different methods under metabolic engineering which are being frequently used for bio-based succinic acid production using representative microorganisms, such as Mannheimia succiniciproducens, Pichia kudriavzevii, Saccharomyces cerevisiae, Actinobacillus succinogenes, Corynebacterium glutamicum, Basfia succiniciproducens, and Escherichia coli. This review summarizes the evolution of microbial production, fermentative methods, various organic substrates and the effects of efforts to recover and refine components for a wide range of applications in the perspective of biologically produced succinic acid for commercialization state.

Published: July 2023

The Gordineşti II-Stînca goală is an archaeological site located in the northern part of the Moldavian Plateau in Edineț Region. Chronologically this settlement is linked to the later phase of the Tripolye Culture. Currently, in archaeological literature, the problems of human occupation, land management, and spatial arrangement of settlements in Moldova during the Eneolithic are highly understudied. In this paper, we present the results of recent archaeological works focusing on the spatial patterning of housing structures, Ground Penetrating Radar (GPR) survey, and desk-based Kernel Density Estimation (KDE) analysis, that has been undertaken to further the understanding of the spatial organisation of the Gordineşti II-Stînca goală settlement. The results indicate the high archaeological potential of this site, with the likely presence of multiple housing structures arranged in a planned and functional manner.

The transsulfuration pathway (TSP) is a metabolic pathway involving sulfur transfer from homocysteine to cysteine. Transsulfuration pathway leads to many sulfur metabolites, principally glutathione, H2S, taurine, and cysteine. Key enzymes of the TSP, such as cystathionine β-synthase and cystathionine γ-lyase, are essential regulators at multiple levels in this pathway. TSP metabolites are implicated in many physiological processes in the central nervous system and other tissues. TSP is important in controlling sulfur balance and optimal cellular functions such as glutathione synthesis. Alterations in the TSP and related pathways (transmethylation and remethylation) are altered in several neurodegenerative diseases, including Parkinson’s disease, suggesting their participation in the pathophysiology and progression of these diseases. In Parkinson’s disease many cellular processes are comprised mainly those that regulate redox homeostasis, inflammation, reticulum endoplasmic stress, mitochondrial function, oxidative stress, and sulfur content metabolites of TSP are involved in these damage processes. Current research on the transsulfuration pathway in Parkinson’s disease has primarily focused on the synthesis and function of certain metabolites, particularly glutathione. However, our understanding of the regulation of other metabolites of the transsulfuration pathway, as well as their relationships with other metabolites, and their synthesis regulation in Parkinson´s disease remain limited. Thus, this paper highlights the importance of studying the molecular dynamics in different metabolites and enzymes that affect the transsulfuration in Parkinson’s disease.
A New Insight into Concrete Impermeability: Effect of Polymer Modification of Interfacial Transition Zone
Authors: Yang Shuang , Wang Jiantao , Li Wen , Wang Yingxiang , Liu Yunpeng
Published: July 2023

Coarse aggregates were pretreated with asphalt emulsion to concentrate asphalt film in the interfacial transition zone (ITZ) so as to improve concrete impermeability at a relatively low polymer content. Several test methods, including artificial crack samples, model aggregate concrete, and surface element scanning, were employed to characterize the contribution of modified ITZ to concrete impermeability. The results showed that incorporating hydrophobic asphalt film in ITZ could simultaneously slow down water absorption while weakening the ITZ microstructure. The water absorption of concretes decreased with an increase in the asphalt content and asphalt-coated aggregates ratio. However, the rapid chloride migration tests showed different results, which could be attributed to the different water saturation states of concretes before the tests. The hydrophobic asphalt film could retard water absorption and, consequently, chloride ion diffusion, even in the presence of cracks.
Quantum Mechanical-Based Fracture Behavior of L-PBF/SLM Ti-6Al-4V in the Very High Cycle Fatigue Regime
Authors: Awd Mustafa , Saeed Lobna , Walther Frank
Published: July 2023

This work predicts bulk elastic properties and solves the wave function probabilistically using the density functional theory and by fixing outcomes with instrumented indentation. Revised bulk properties may predict crack start and propagation. Author-scripted pre- and post-processing in Abaqus simulated crack spread. Ultrasonic fatigue simulations increased fatigue life because the fracture onset phase was longer. We demonstrate that fatigue strength relies on elastic modulus because they are correlated. The verified results do not depend on any experimental evidence. Machine systems and scanning technologies have boosted the usage of selective laser-melted materials, leading to virtually full-density products. Microstructure and porosity from powder melting generate inconsistent mechanical performance under cyclic load. The extended finite element method was used to simulate crack propagation over an arbitrary fracture path to analyze fatigue crack development in additively generated fatigue specimens. Using fracture energy rate curves, loading level and testing frequency were evaluated on fatigue life. Micro computerized tomography (µ-CT) scans provide two-dimensional angular pictures. Several methods minimize faces and vertices. Open-source software was utilized to construct finite element models using µ-CT projections and to separate the cylindrical shell from internal pores. Crack propagation rate curves were used to investigate the impacts of loading level and testing frequency.
AIDS or HIV Education and Sexual Behaviors Among Adolescent Sexual Minority Males: National HIV Behavioral Surveillance, 3 U.S. Cities, 2015
Authors: Robbins Taylor , Szucs Leigh E. , Trujillo Lindsay , Young Emily ,   for the NHBS-YMSM Study Group
Published: July 2023

In the U.S., HIV transmission rates have increased among male-male sexual contacts. Sex education reduces HIV-related risks; yet impacts for adolescent sexual minority males (ASMM) are less known. Data from a sample (n = 556) of ASMM (aged 13-18) in three U.S cities were used to examined associations between HIV education in school and sexual behaviors. Outcomes of interest included: sexually transmitted infection (STI), multiple sex partners, and condomless anal intercourse (CAI) with a male (all past 12 months). Adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were calculated. Of 556 ASMM, 84% reported received HIV education. Among sexually active ASMM (n = 440) who received HIV education, fewer reported an STI (10% vs. 21%, aPR: 0.45, CI [0.26, 0.76]) and CAI (48% vs. 64%, aPR: 0.71, CI [0.58, 0.87]) than ASMM who did not receive HIV education. Protective effects of school HIV education on sexual behaviors are promising and suggest prevention education is vital to reducing HIV- and STI-related risks among ASMM.

Published: July 2023

HIV pre-exposure prophylaxis (PrEP) is highly effective, but PrEP use has been suboptimal. We describe a telementoring program for clinics in high-HIV burden areas, focusing on systems-level practice transformation and care for populations disproportionately affected by HIV. We developed and delivered a telementoring program for U.S. health centers. We analyzed participants' baseline and post-session surveys to ascertain experiences providing PrEP and caring for people disproportionately affected by HIV, comparing responses between medical and behavioral health clinicians. Forty-eight people from 16 health centers participated. Medical clinicians were more likely than behavioral health clinicians to care for people taking PrEP, but the groups did not differ in self-rated capacity to counsel about PrEP or care for populations disproportionately affected by HIV. Virtual training on practice transformation for PrEP, involving medical and behavioral health clinicians, is feasible and acceptable. PrEP training and delivery efforts should include behavioral health clinicians.

Authors: Petry Michele Bete , Vaz Alexandre Fernandez
Published: July 2023

Propondo uma reflexão sobre os lugares e modos de expor a arte, apontamos para a tese de que as revistas teriam funcionado como lugares de exposição da arte gráfica no Rio de Janeiro, no final do século XIX e início do século XX. Em razão disso, investigamos a presença da arte nessas revistas por meio de uma análise expográfica sobre os seus programas de apresentação (“programas de curadoria”) e seus projetos gráficos (“projetos de expografia”), apontando para as propostas de crítica e propaganda, na revista A Cigarra e O Mercurio, e de crítica e humor, na Revista da Semana e O Malho. Ou seja, respectivamente, para a presença do que denominamos de Arte do Espetáculo e Arte Nova.
A CONSTRUÇÃO DO NARRADOR EM NARRATIVAS ESCRITAS POR INDÍGENAS BRASILEIROS
Authors: Zanelatto Santos Rosana Cristina , Oliveira Ana Luiza Postingher
Published: July 2023

Este trabalho objetiva apresentar uma reflexão sobre as narrativas dos povos ameríndios, compreendendo-as como parte significativa das culturas de seus povos e dos indivíduos que as narram, sendo essenciais para o entendimento de visões de mundo e de sujeitos diferentes daqueles plasmados no cânone da Literatura Ocidental. Por meio das proposições teóricas de Aristóteles, de Librandi-Rocha e de Thiél, que apresentam a possibilidade de se repensar as noções de história, de ficção e de mímesis por meio da Literatura Ameríndia, a pergunta que guiou este trabalho foi sobre a existência ou não de uma alteridade do narrador indígena e, se existe, como essa alteridade se constitui. Além disso, foram utilizadas as proposições de Walter Benjamin sobre o narrador para se pensar o lugar ocupado pelo narrador na Literatura Ameríndia. Foram pensadas, também, as aproximações e as diferenças no que tange às tradições oral e escrita de contar histórias, buscando altercar nas discussões o lugar de referência e de alteridade, como proposto por Pedro Cesarino, Librandi-Rocha e como manifesto por Ailton Krenak. Para tanto, foram selecionados como corpora textos escritos por indígenas da comunidade Terena, situada no Pantanal de Mato Grosso do Sul, quando de um projeto em parceria com o Instituto de Pesquisa da Diversidade Intelectual (IPEDI). Pondera-se, ainda, de forma breve, sobre a possibilidade ou não de se pensar a Literatura Ameríndia como constituinte também de seu próprio entrelugar, tomando aqui o conceito cunhado por Silviano Santiago.
O GÓTICO FEMININO EM JULIA LOPES DE ALMEIDA: UMA ANÁLISE DE “OS PORCOS”
Authors: Araújo Naiara Sales , Oliveira da Silva Lucélia Magda
Published: July 2023

O presente estudo visa a fazer uma reflexão acerca da estética do gótico feminino no conto “Os Porcos” (1903), de Júlia Lopes de Almeida. O ingresso das mulheres no mercado literário possibilitou o surgimento de vozes femininas favorecendo a eclosão de narrativas que expusessem a vivência da mulher em sociedade, bem como seus anseios, problemas e ansiedades. Como aporte teórico, utilizamos os contributos de Ana Paula dos Santos (2017), Ellen Moers (1976) e Edmund Burke (2016), dentre outros importantes críticos do universo fantástico e do horror. Como resultado, é possível verificar que Almeida utilizou muitas das características da estética gótica europeia para fazer um panorama dos principais anseios e tensões sociais que envolvem a relação mulher e sociedade, no Brasil.
LO REAL MARAVILLOSO: ENTRE LA CRÍTICA FORMAL Y LA INDEPENDENCIA POLÍTICA
Authors: Nicotera Pablo Francisco
Published: July 2023

El uso de la categoría de influencia en América Latina supone una condición colonial otorgada a la literatura del continente, como sistema literario subsidiario de países centrales (tanto de Europa como EE.UU.). Pensada por la crítica que estos practican, la influencia descansa sobre el presupuesto de que la literatura latinoamericana es incapaz de generar un producto original y debe ser reducida a modificar los modelos que llegan desde las metrópolis. En ese sentido, este artículo se centra en la crítica efectuada a lo Real Maravilloso, que puede asociarse a dos grupos más o menos definidos: un primer grupo que, desde un punto de vista formal, se ocupa de rastrear influencias (Anderson Imbert, Fuentes y Rodríguez Monegal), fundamentalmente de literaturas hegemónicas, trazar genealogías, que terminan por socavar lo que ese modo de hacer literatura tiene de original americano. Otro grupo (Uslar Pietri, Carpentier, Vargas Llosa y Rama), que desbarata la noción de influencia para plantear, desde una posición política de defensa, una originalidad de lo Real Maravilloso que tiene que ver con una forma de percibir la realidad desde una cultura cuya identidad se relaciona con el mestizaje y propone una literatura que trasciende el juego del lenguaje.

Para isso, dialogamos com os estudos de Coutinho (2006), Rebello (2007) e Pedroso Júnior (2016), acrescentando a eles perspectivas contemporâneas, depoimentos recentes ao projeto Memória da ABRALIC (2020) e informações compiladas por meio de consultas a periódicos acessíveis digitalmente. Ao fim, sugerimos encaminhamentos futuros para os temas propostos.
DE GAUCHOS, CHINAS Y FOGONES: UN ACERCAMIENTO A LOS TOPOI CRIOLLOS ASOCIADOS A LA MILONGA CAMPERA EN LOS AIRES DE LA PAMPA DE ALBERTO WILLIAMS
Authors: Cerletti Adriana Valeria
Published: July 2023

Este artículo se propone trabajar con los tópicos asociados a la milonga campera dentro de la producción pianística de milongas del compositor argentino Alberto Williams (1862-1952). Ubicadas en las series Aires de la Pampa dichas milongas - junto a las huellas y vidalitas - apelan a los géneros folclóricos como “fuentes de inspiración”, vinculándose a la producción nacionalista de la música académica argentina. Para desandar el derrotero del topos de la milonga campera se partirá de la bibliografía tradicional (VEGA, 1944 y ARETZ, 1952) tomando como marco teórico a la Teoría Tópica, especialmente los aportes de Monelle (2006) y Plesch (1996, 2008).  El caso paradigmático de la Op. 64 No 6 Adiós a la tapera permitirá poner en relación al topos del acompañamiento con otras variables musicales para observar cómo interactúan en red. La dirección de la escucha, interpelada por los omnipresentes títulos de temáticas criollistas, se monta sobre el imaginario ya legitimado y ampliamente difundido por la literatura gauchesca y el circo criollista silenciando la tipología de la milonga bailada.
La crítica como ejercicio contraideológico
Authors: Croce Marcela
Published: July 2023

Entre los múltiples errores que atormentan a la crítica literaria latinoamericana, uno de los más contumaces es el de fascinarse con las teorías que se esparcen por la academia norteamericana y que ingresan subrepticiamente –a través de voceros desfachatados que las presentan como “novedad” y las insertan bajo la etiqueta feraz de “actualización”– a las universidades que al sur del río Bravo se avergüenzan de no producir algo tan amplio y expansivo. La razón de ese oprobio injustificado ante la presunta esterilidad local es que los latinoamericanos saben de sobra que no todos los subalternos son homologables ni todos los colonizados forman un continuum al que se pueden aplicar tales “iluminaciones” sin recaudos, sean estos ajustes radicales o rechazos enfáticos. Solamente una mentalidad colonizadora puede imaginar que existen modelos destinados a comprender grandes conjuntos sin otro esfuerzo que el de simplemente enunciarlos y encontrar, parafraseando al Rousseau del Discurso sobre el origen de la desigualdad entre los hombres, suficientes desprevenidos dispuestos a creerlo y a asentir.

Este estudo tem por objetivo analisar o tempo-espaço do bosque na narrativa do musical Into the Woods, de James Lapine e Stephen Sondheim (2014), com base no conceito de cronotopo, conforme desenvolvido pelo teórico russo Mikhail Bakhtin (2018 [1975]). Em seu enredo próximo ao conto de fadas do tipo artístico, a peça estabelece relações dialógicas  também com contos de fadas populares e atualiza os sentidos da jornada de cada personagem por meio de motivos e elementos essencialmente cronotópicos. Por fim, o cronotopo do bosque atua como o fio-condutor do musical, servindo de base para os acontecimentos do enredo e reunindo as jornadas de diferentes personagens em um quadro espaçotemporal comum.
Asymmetric Voltage Attenuation in Dendrites Can Enable Hierarchical Heterosynaptic Plasticity

Long-term synaptic plasticity is mediated via cytosolic calcium concentrations ([Ca2+]). Using a synaptic model that implements calcium-based long-term plasticity via two sources of Ca2+— NMDA receptors and voltage-gated calcium channels (VGCCs) — we show in dendritic cable simulations that the interplay between these two calcium sources can result in a diverse array of heterosynaptic effects. When spatially clustered synaptic input produces a local NMDA spike, the resulting dendritic depolarization can activate VGCCs at nonactivated spines, resulting in heterosynaptic plasticity. NMDA spike activation at a given dendritic location will tend to depolarize dendritic regions that are located distally to the input site more than dendritic sites that are proximal to it. This asymmetry can produce a hierarchical effect in branching dendrites, where an NMDA spike at a proximal branch can induce heterosynaptic plasticity primarily at branches that are distal to it. We also explored how simultaneously activated synaptic clusters located at different dendritic locations synergistically affect the plasticity at the active synapses, as well as the heterosynaptic plasticity of an inactive synapse “sandwiched” between them. We conclude that the inherent electrical asymmetry of dendritic trees enables sophisticated schemes for spatially targeted supervision of heterosynaptic plasticity.

In 2021, 131 million adult Americans reported drinking alcohol in the last month, despite the well-known consequences of alcohol consumption. While alcohol use disorders (AUDs) are associated with both mood and chronic pain disorders, the relationship between alcohol drinking and affective and nociceptive behaviors remains unclear. Corticotropin releasing factor receptor-1 (CRF1) has been implicated in alcohol drinking, affective states, and pain sensitivity, often in a sex-dependent manner. In order to probe the effects of alcohol drinking on activity of CRF1+ cells and to also test the hypothesis that alcohol drinking is associated with both basal and subsequent affective and nociceptive readouts, we put male and female CRF1:cre:tdTomato rats through a battery of behavioral tests before and after intermittent access to alcohol. Following baseline testing, rats began alcohol (or water) drinking. Females consumed more alcohol in the first week, but there was no effect of sex on overall alcohol intake. Following three to four weeks of drinking, behavioral tests were repeated. Alcohol drinking decreased mechanical sensitivity, but no other effects of alcohol drinking were observed between experimental groups. Individual alcohol intake correlated with affective behavior in both sexes but only correlated with thermal sensitivity in males. There were no main effects of alcohol drinking or sex on CRF1+ neuronal activity in the medial prefrontal cortex (PFC) but final session alcohol intake correlated with activity in CRF1+ neurons in the infralimbic (IL) subregion. Together, our results suggest complex interplay between affective state, alcohol drinking, and the role of prefrontal CRF1+ neurons in mediating these behaviors.
Reorienting Mexicanidad and the Catholic Narrative
Authors: Eckmann Teresa
Published: July 2023

From his provincial origins in the small northern Mexico town of Múzquiz, Coahuila, to achieving international standing at the time of his early death at the age of forty-seven, Julio Galán (1958–2006) crossed borders between Monterrey, New York City, and Paris to emerge among Neo-Expressionist and neomexicanista artists of the 1980s as radically transgressive in his self-representation. Galán combined gender-fluid imagery, a performative persona, queer self-representation, and cross-cultural visual and textual references to create large-scale, layered, dialogical visual puzzles. Establishing the centrality of Catholic ritual and doctrine in his artwork, this paper closely examines a selection of unpublished family photographs, preparatory sketches, paintings, still performances, and installations generated over the course of his career that emerged from Galán’s personal, conflicted relationship with Catholicism. Through self-portraiture, he embodied Jesus Christ and the Virgin Mary, weighing relationships between divine and human. He transformed and recontextualized religious symbols in his art, combining them with the popular and the everyday, the carnal and erotic, to bridge the divide between the sacred and the profane. Drawing from queer theory, cultural criticism, film criticism, and visual analysis, this study shows that Galán engaged with religious symbols in his art to insist on the inclusionary, a position that maintains social relevance today, particularly with the LGBTQ+ struggle for visibility and civil rights.

Invasive bacteria enter the cytosol of host cells through initial uptake into bacteria‐containing vacuoles (BCVs) and subsequent rupture of the BCV membrane, thereby exposing to the cytosol intraluminal, otherwise shielded danger signals such as glycans and sphingomyelin. The detection of glycans by galectin‐8 triggers anti‐bacterial autophagy, but how cells sense and respond to cytosolically exposed sphingomyelin remains unknown. Here, we identify TECPR1 (tectonin beta‐propeller repeat containing 1) as a receptor for cytosolically exposed sphingomyelin, which recruits ATG5 into an E3 ligase complex that mediates lipid conjugation of LC3 independently of ATG16L1. TECPR1 binds sphingomyelin through its N‐terminal DysF domain (N'DysF), a feature not shared by other mammalian DysF domains. Solving the crystal structure of N'DysF, we identified key residues required for the interaction, including a solvent‐exposed tryptophan (W154) essential for binding to sphingomyelin‐positive membranes and the conjugation of LC3 to lipids. Specificity of the ATG5/ATG12‐E3 ligase responsible for the conjugation of LC3 is therefore conferred by interchangeable receptor subunits, that is, the canonical ATG16L1 and the sphingomyelin‐specific TECPR1, in an arrangement reminiscent of certain multi‐subunit ubiquitin E3 ligases.

UBR5 is a nuclear E3 ligase that ubiquitinates a vast range of substrates for proteasomal degradation. This HECT domain‐containing ubiquitin ligase has recently been identified as an important regulator of oncogenes, e.g., MYC, but little is known about its structure or mechanisms of substrate engagement and ubiquitination. Here, we present the cryo‐EM structure of human UBR5, revealing an α‐solenoid scaffold with numerous protein–protein interacting motifs, assembled into an antiparallel dimer that adopts further oligomeric states. Using cryo‐EM processing tools, we observe the dynamic nature of the UBR5 catalytic domain, which we postulate is important for its enzymatic activity. We characterise the proteasomal nuclear import factor AKIRIN2 as an interacting protein and propose UBR5 as an efficient ubiquitin chain elongator. This preference for ubiquitinated substrates and several distinct domains for protein–protein interactions may explain how UBR5 is linked to several different signalling pathways and cancers. Together, our data expand on the limited knowledge of the structure and function of HECT E3 ligases.

Generally, public service interpreters and social workers experience symptoms of an anxious depressive nature, due to their works. For this reason, we aimed to design three ad hoc emotional management intervention programs to evaluate their impact, combining quantitative and qualitative information. The study developed a quasi-experimental pre-test-post-test design, performing T-tests on related samples for each group. Three ad hoc intervention programs were developed for a group of public service interpreters, a group of telephone interpreters and a group of social workers. The study also included a control group that did not receive any intervention. The Bar-On ICE, the Interpersonal Reactivity Index (IRI) and the BCSQ-36 were used to evaluate the Emotional Intelligence factors, the Burnout syndrome and the Empathy processes. Most of the emotional intelligence and empathy factors showed statistically significant differences between the pre-test and the post-test, in favor of the latter for each of the groups. The control group’s T2 results worsened, as they had not received any form of intervention. This paper will discuss how these participants have incorporated the key takeaways of the intervention programs in their emotional management at work.
