Published: November 2024

This paper reports a study aimed at assessing fire resistance of reinforced concrete ribbed slabs at the onset of integrity loss limit state. EN 1992-1-2 lacks calculation methodology for determining the limit of fire resistance of reinforced concrete slabs when the limit state of integrity loss occurs. Scientific works are focused on two limit states of fire resistance: load-bearing capacity and heat-insulating capacity. Experimental tests are criticized because of difficulties in registering signs of the onset of the limit state of loss of integrity, in particular due to the need to control the unheated surface of the ribbed plate during a fire under the action of mechanical load. Therefore, there is no calculation methodology for assessing the fire resistance of reinforced concrete ribbed slabs upon the onset of the limit state of loss of integrity. At the same time, to ensure the safe evacuation of people in the event of a fire, to prevent the spread of fire, as well as to carry out the effective work of rescuers, it is necessary to use building structures with guaranteed fire resistance classes.
The paper reports the results of solving thermal engineering and static problems, which relate to the temperature distribution and stress-strain state of the investigated ribbed plate. Conducting research into the fire resistance of reinforced concrete ribbed slabs, taking into account the onset of the limit state of loss of integrity, made it possible to establish the dependence of the fire resistance limit of these structures on the loss of integrity on the level of applied mechanical load. The resulting dependence plot makes it possible to evaluate reinforced concrete ribbed slabs according to the criterion of the onset of the limit state of loss of integrity, which provides an opportunity to determine fire resistance more objectively

Authors: Rolik O. I. , Zhevakin S. D.
Published: November 2024

Context. In recent years, the topic of deploying informational infrastructure in a multi-cloud environment has gained popularity. This is because a multi-cloud environment provides the ability to leverage the unique services of cloud providers without the need to deploy all infrastructure components inside them. Therefore, all available services across different cloud providers could be used to build up information infrastructure. Also, multi-cloud offers versatility in selecting different pricing policies for services across different cloud providers. However, as the number of available cloud service providers increases, the complexity of building a costoptimized deployment plan for informational infrastructure also increases.
Objective. The purpose of this paper is to optimize the operating costs of information infrastructure while leveraging the service prices of multiple cloud service providers.
Method. This article presents a novel cost optimization method for informational infrastructure deployment in a static multicloud environment whose goal is to minimize the hourly cost of infrastructure utilization. A genetic algorithm was used to solve this problem. Different penalty functions for the genetic algorithm were considered. Also, a novel parameter optimization method is proposed for selecting the parameters of the penalty function.
Results. A series of experiments were conducted to compare the results of different penalty functions. The results demonstrated that the penalty function with the proposed parameter selection method, in comparison to other penalty functions, on average found the best solution that was 8.933% better and took 18.6% less time to find such a solution. These results showed that the proposed parameter selection method allows for efficient exploration of both feasible and infeasible regions.
Conclusion. A novel cost optimization method for informational infrastructure deployment in a static multi-cloud environment is proposed. However, despite the effectiveness of the proposed method, it can be further improved. In particular, it is necessary to consider the possibility of involving scalable instances for informational infrastructure deployment.

Updating Approaches to Studies of Economic Space Heterogeneity
Authors:   North Caucasian Institute – Branch of the Russian Presidential Academy of National Economy and Public Administration, Kiseleva Natalia , Khuchiev Muslim ,   Academy of Sciences of the Chechen Republic
Published: November 2024

The article distinguishes the categories of “heterogeneity of economic space” and “interregional social differentiation”, as well as the ways of their assessment. On the basis of the theories of new economic geography and center-periphery theory, the nature of spatial heterogeneity is revealed. The heterogeneity of Russia’s economic space is analyzed through the prism of two key properties of space, i.e., density and connectivity. It is shown that the spatial heterogeneity in terms of population density is growing against the background of decreasing differentiation of space in terms of economic density, measured as GRP per 1 km 2 and volume of investment in fixed capital per 1 km 2 , which can be explained by the fact that the economy is in a phase of recession. A positive correlation between population density and highway density is revealed, which can be explained by the discreteness of space. Based on empirical data, the authors conclude that communicative compression of economic space is characteristic of regions with high population density and economic density and regions with extremely low population density and transport connectivity. In the first case, it is evidence of high business activity in the territory, while in the second case it is a way to increase the availability of services. Based on the comparison of population density and economic density of space, four types of territories were identified: territories of spatial compression; territories with growing population density against the background of high economic density of space; and territories characterized by high population density with relatively low density of economic space; territories with relatively low population density and a trend for its further reduction against the background of high economic density of space. The priorities of spatial development are defined for each type of territory.
Molecular approach in elite parents of papaya with a focus on seed physiological quality
Authors: Gregolin Fernanda Schmitt , Vieira Henrique Duarte , Santa-Catarina Renato , Viana Alexandre Pio
Published: November 2024

Abstract: Papaya seeds have natural barriers (phenolic compounds, seed structure and genetic factors) that make their germination difficult. And the use of seeds is the main means of propagating the species, whether for commercial cultivation, maintenance of germplasm or selection of genetic materials. Thus, the use of seeds with physiological quality (germination, normal seedlings and germination speed) is fundamental to the production of vigorous plants. However, few studies have been developed with the aim of evaluating and improving seed quality. From this perspective, the study aims to evaluate the quality of seeds in genetic materials widely used to obtain new genotypes, in order to identify superior materials and possible crosses between those that have high physiological seed quality. For this purpose, 44 genotypes were analyzed by molecular characterization, via microsatellite markers (observed and expected heterozygosity, number of alleles, information index, fixation index, inbreeding coefficient, genetic structure and genetic dissimilarity via UPGMA grouping), as well as determining physiological quality of the seed (germination speed index, percentage of germination and abnormal seedlings). Among the genotypes, 10 have germination above 60%, a high rate of germination speed and a low percentage of abnormal seedlings, and can be used in crosses to improve seed quality. The dissimilarity analysis was able to highlight the dissimilarity between the accessions of the Solo and Formosa groups. The use of the dissimilarity coefficient and the number of shared alleles made it possible to identify 18 possible crosses promising to improve the quality of papaya seeds.

Published: November 2024

Abstract: The fruit fly is one of the major citrus pests. The study aimed to evaluate the repellency of citronella oil against Bactrocera spp. in citrus. The two experiments were carried out in a farmer’s citrus orchard in Junrejo, East Java, Indonesia from August to December 2022. In the first experiment, a randomized block design with five treatments and four replications was employed in the field to evaluate the potential repellency of citronella against Bactrocera spp. The treatments consisted of various mixtures of citronella and methyl eugenol. In the second experiment, the effect of one and two applications of 2 mL /L of citronella per week and synthetic pesticide on the population of Bactrocera spp. were compared. The results showed that citronella had a repellent capacity against Bactrocera spp. The number of pests trapped in citronella traps was lower than those captured in Methyl Eugenol traps only. The effectiveness of citronella as repellent for ten days. The one spraying per week of citronella was more efficient and effective in controlling Bactrocera spp. than other treatments. The use of citronella as a repellent could be integrated with the existing technologies to form an environmentally friendly package of fruit fly control approach.
Phenological and productive aspects of grape varieties subjected to two pruning seasons in Vale do Rio do Peixe, SC
Authors: Souza André Luiz Kulkamp de , Bender Angelica , Costella Maria Rosa dos Santos
Published: November 2024

Abstract: Pruning of grape varieties for processing typically occurs in winter. However, due to challenges in availability and labor costs, there is interest in shifting this practice to autumn—a period with lower demand for vineyard activities. This study aimed to assess the direct influence of autumn pruning on the phenological and productive performance of Niágara Rosada, Isabel Precoce, and Bordô varieties in the Vale do Rio do Peixe region, SC. Experiments were conducted during the 2015, 2016, 2017, and 2018 harvests in fully productive commercial vineyards located in Videira-SC. Pruning occurred in May (autumn) and August (winter). Autumn pruning took place when approximately 5% of the leaves had fallen, and the rest had turned yellow. Winter pruning occurred during the bud swelling stage. Weekly phenological monitoring, as well as measurement of the plants’ productive characteristics and the physical-chemical composition of the grapes, were conducted. Autumn pruning enhanced the productivity, average bunch weight, and uniformity of maturation for Niagara Rosada but accelerated the bud break for this variety in Vale do Rio do Peixe, SC, Brazil. In Bordô, autumn pruning did not affect productivity, but it advanced bud break. Conducting autumn pruning for four consecutive years decreased the productivity of Isabel Precoce.

Published: November 2024

Abstract: Suicidal behavior and non-suicidal self-harm in vulnerable groups and population minorities pose a challenge for suicidology, complicating the universality of suicide. The goal of this paper is to analyze the lives of young women from marginalized communities, considering their experiences with suicidality and their relational and violent horizons. Nine women who took part in the fifth wave of a cohort on mental health and violence (2005-2022) in São Gonçalo, Rio de Janeiro State, Brazil, were interviewed (2022) about the contexts that kept them from committing suicide despite significant emotional distress from childhood through youth. From theme-based content analysis, three categories stood out and may contribute to an intersectional, decolonial and socially relevant approach to preventing self-destructive behavior. In the first, views on self-inflicted violence, better explained by the cores concepts of “sin” and “illness” than by the general violence they experienced. In the second, indirect references to self-harm behavior, where it was recognized that the use of euphemisms reflects not only the taboo but also the silencing of and discrimination against minorities. In the third, layers of protection and turning points, where “spirituality”, “occupation” and “motherhood” were interpreted as the main associations between factors of protection and resilience in the trajectories and daily lives of these young women. A closer look that acknowledges the humanity, rights and psychological distress of groups subjected to violence and discrimination not only enhances care and prevention of suicidal behavior but also deepens understanding of this human and universal phenomenon.

Published: November 2024

Resumo Estudos indicam a intensificação das mudanças climáticas, com aumento da temperatura do ar, alterações no padrão das chuvas e maior variabilidade para outros elementos climáticos. O setor energético renovável pode contribuir com a redução dos impactos na atmosfera. Todavia, as fontes renováveis dependem do clima e o aumento da demanda por energia exige um planejamento coerente com as novas condições. Este estudo teve como objetivo apresentar os resultados relacionados à radiação solar incidente na superfície e à nebulosidade para o Nordeste brasileiro. Utilizou-se um conjunto de modelos climáticos globais (BESM, HadGEM2-ES e CanESM2) associados ao regional Eta, para projetar dados futuros para os períodos de 2041-2069 e 2070-2099, comparando-os ao período histórico de 1961-1990, considerando os cenários RCP4.5 e RCP8.5 aplicados pelo Painel Intergovernamental sobre Mudanças Climáticas. Os resultados evidenciaram o aumento predominante da radiação solar incidente (média de 1,7% pelo HadGEM2-ES e 2,5% pelo CanESM2), exceto para o BESM (-3,5%) e redução para a nebulosidade, com valores médios entre -1,1% (BESM) e -53,4% (CanESM2). Esses resultados podem favorecer a produção de energia solar fotovoltaica nesta região, sendo assim, tem-se elevada expectativa quanto à diversificação da matriz energética brasileira, redução da dependência de combustíveis fósseis e aumento da segurança energética.

Published: November 2024

ABSTRACT: The environmental regulation of continental fish farming in Brazil is closely linked to land occupation and use. Areas used for this activity are mostly located in permanent preservation areas (PPA), close to rivers and springs, demonstrating the necessity of regulating this activity for its compliance with public policy. Santa Catarina is a leading state in fish farming and one of the first to regulate the use of PPAs. The feasibility of a proposal for environmental compensation to regularize the use of PPAs in Santa Catarina for fish farming; was therefore, assessed. The results showed that 74% of the fish farms analyzed need to regularize the occupation of production structures in PPAs. Regarding the proposed index of compensation for use in PPAs, the environmental compensation factor (ECF), through evaluation of the individual maps and subsequent integrated evaluation, all the fish farms identified with environmental liabilities in occupation had ratios of 1:2 and 1:3, and this index is a viable alternative for environmental regularization of the activity. It was further proposed that ECF be applied to small fish farms of up to four fiscal modules and that they have a standard minimum occupancy profile in relation to the total area of the property, as assessed in the present study.

ABSTRACT: The structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and survival of the species. Scientific research plays an important role in generating technologies and the security of applications. However, there is a need to refine the content generated to analyze discoveries and trends on the subject. Therefore, the present study conduct a bibliometric review and analysis on the main contributions of relevant studies, researchers, organizations, and countries in academic research on the rooting of Coffea canephora in the Web of Science (WOS) database. Data from the WOS database published between 1982 and 2021 and systematized in the VOSviewer software showed a set of 92 articles, the majority of which originated in Brazil and France, with the main groups being the Brazilian Agricultural Research Corporation, the Federal University of Viçosa, and CIRAD. The study was divided into five areas: genetic diversity, asexual propagation, nematology, tolerance to water stress, and micropropagation. However, in the context of climate changes and its impact on the production and longevity of Brazilian coffee farming, research focused on the root system has increased significantly, integrating it into lines that explore and integrate topics such as climate risk, water management, drought tolerance, and drip irrigation, including reflections on the performance of coffee agronomy.

Abstract Culicoides is a small dipteran genus of Ceratopogonidae Family with worldwide distribution. Due to their hematophagous habits, species within this genus are a biting nuisance to humans and domestic animals. They also transmit protozoa, filarial worms, and several arboviruses. The Northeastern region of Brazil is characterized by a semi-arid climate and few bodies of water, which does not favor breeding sites for ceratopogonids. In addition to the climatic factor, studies on Biting Midges Culicoides are scarce in this geographic region. The municipality of Pacoti, located in Serra de Baturité, in Ceará, is an important area for agricultural production and ecotourism; also, Pacoti is located in an environmental protection area. Due to the medical and veterinary importance of these biting midges, a survey was conducted in Pacoti. For capture, CDC-type light traps were used near forested areas, where collections were carried out during two periods: March 2015, and August 2022. Of the 17 species found, 12 are new records for the municipality of Pacoti, nine are new records for the state of Ceará, and four are recorded for the first time for the Northeast region. Of the registered incriminated vectors, we found C. paraensis, C. insignis, and C. pusillus. The knowledge of biodiversity and geographic distribution update of Culicoides may contribute to prevention and control measures for vector-borne diseases in Ceará.
Global research output on antimicrobial resistance in dairy farming
Authors: Kaplan Selçuk
Published: November 2024

ABSTRACT Antimicrobials are pivotal in treating bacterial infections. More often than any other class of antimicrobial, antibiotics are a class of antimicrobials used primarily to treat bacterial infections. Thus, both human health and life longevity, as well as the welfare of animals, have greatly improved with the development of antibiotics as a means of treating infectious diseases. Dairy farming is essential to satisfying the world's demand for dairy products. Nevertheless, improper use of antibiotics in dairy farming contributes greatly to the formation of antimicrobial resistance. Moreover, the resulting antimicrobial resistance can be transferred to humans by consuming contaminated dairy products. Therefore, the scientific community has been intensively studying the relationship between dairy farming and antimicrobial resistance since 1983. And, due to the increasing awareness of antimicrobial resistance worldwide, studies on antimicrobial resistance in dairy farming have rapidly increased 89 times in the last twenty years. Today, the development of antimicrobial resistance in dairy farming is among the trending research topics. For this purpose, this study is the first bibliometric approach that aims to guide future studies by revealing all aspects of the studies on this subject between 1983 and 2023.

ABSTRACT: Analyzing the causes of death in dogs is fundamental for controlling and preventing diseases, thereby promoting greater longevity and quality of life. However, the current literature lacks standardization and uniformity in the diagnostic description, forms, and instruments for collecting data and maintaining dog obituary records. Using data from the Data Platform of the Animal Mortality Information System (DATASIMA), which uses the Declaration of Animal Death and the International Classification of Diseases (ICD-10), the classification of the causes of death of dogs attended by veterinary doctors was conducted at the “Universidade Federal da Paraíba”, from January to December 2022. The causes of death were stratified, promoting their geo-referencing and the characterization of the epidemiological profile of the dogs. A total of 264 cadavers were analyzed, and the most prevalent groups of diseases causing death were pathophysiological disorders (37.87%, n=100), infectious and parasitic diseases (28.4%, n=75), neoplasms (21.59%, n=57), and external causes (12.12%, n=32). The causes of death were categorized according to sex and age range, showing a higher prevalence of pathophysiological disorders and infectious diseases in adults, neoplasms in elderly dogs, and infections and parasitic diseases and pathophysiological disorders in offspring. The findings of this study demonstrate the feasibility of using DATASIMA for the mapping and standardization of data on the causes of animal death, allowing for strategies for intervention in public health, the prevention of zoonoses, the reduction of garbage codes, better and more efficient communication between veterinary doctors, and the possibility of using ICD-10 to classify the causes of animal death.

Published: November 2024

ABSTRACT: Poultry and poultry products are considered the predominant sources of Salmonella enterica contamination and are important reservoirs of bacteria with antimicrobial resistance. The objective of this study was to identify Salmonella with multidrug resistance (MDR) phenotype, with the ability to form biofilms and elucidate the presence of genes that encode antimicrobial resistance in isolates from the broiler production chain in the state of Maranhão, Brazil. A total of 121 strains of S. enterica of different serovars were evaluated for antimicrobial susceptibility, and of these, 26 strains were used to detect the ability to form biofilms and identify resistance genes using PCR. Antimicrobial resistance was observed in 95 (78.5%) Salmonella isolates, and 57 (47.1%) showed MDR phenotype. The isolates showed greater resistance to the sulfonamide principles (58.7%), trimethoprim (48.8%), tetracycline (45.4%), nalidixic acid (44.6%), amoxicillin and ampicillin (26.4%), and cefazolin (22.3%). Salmonella Schwarzengrund (n=21/61.7%), Albany (n=15/62.5%), and Enteritidis (n=4/44.5%) showed the highest indices of MDR phenotype. The ability to form biofilms at 37°C was found in 13 of the 26 strains evaluated, which were considered poor producers. The resistance genes blaCTX-M, blaCTX-M2, blaSHV, sul1, sul2, tetA, tetB, tetC, tetE, dfrA12, and dfrA1 were observed in the serovars Schwarzengrund, Albany, Enteritidis, Heidelberg, and Typhimurium. The results showed a high occurrence of S. enterica, with multiple resistance to conventional antimicrobials and the ability to form biofilms in the poultry production chain.

Published: November 2024

ABSTRACT Coelogyne pandurata L., an orchid native to Indonesia, has medicinal properties and potential for lowland cultivation. This study assessed the phenolic and flavonoid contents and antioxidant activity of the leaves, bulbs, and flowers in the vegetative and generative phases of C. pandurata. The total phenolic content (TPC) and total flavonoid content (TFC) were measured using colorimetric methods. The antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and ferric-reducing antioxidant power (FRAP) assays. Plant parts (leaves, bulbs, and flowers) were analyzed across two phenological phases (vegetative and generative) with three replicates for each combination. Each experimental unit comprised five biological replicates. The extracts were prepared via ultrasonic extraction using methanol, ethanol, and n-hexane. The range of TPC was 2.51-11.44 mg gallic acid equivalent per g dry weight (DW), that of TFC was 6.05-38.16 mg quercetin equivalents per g DW, that of the DPPH antioxidant activity was 0.21-1.41 µmol Trolox equivalent (TE) per g DW, and that of the FRAP capacity was 15.63-80.70 µmol TE g−1 DW. Ethanol extracts, particularly from preflowering bulbs, exhibited the highest TPC, TFC, and antioxidant activity, underscoring its superior extraction efficiency for C. pandurata.

Published: November 2024

ABSTRACT Adequate seed placement is essential for consistent crop emergence and initial growth. Pneumatic seed metering systems offer superior longitudinal seed distribution accuracy compared to traditional methods, yet certain factors can influence this precision. For instance, seed physical properties may be altered by phytosanitary treatments applied either on-farm or industrially. This study examined the effects of phytosanitary treatment type and graphite addition on soybean seed deposition using an electric-driven pneumatic feeder under simulated sowing conditions. Seed distribution was monitored with an optical sensor. Four treatment groups were established: untreated without graphite, untreated with graphite added, on-farm treated with graphite, and industrially treated with graphite. Parameters assessed included average spacing between seeds, coefficient of variation, precision index, multiple and failed spacings, and percentage of acceptable spacing. Results indicate that prior seed treatment does not significantly affect overall planting accuracy. However, seed spacing varied between the untreated and on-farm treated groups, with the latter demonstrating closer proximity to optimal values. Both on-farm and industrial treatments yielded more uniform seed deposition, as indicated by a lower coefficient of variation. Regardless of seed treatment, the pneumatic feeder consistently performed effectively.

Published: November 2024

Abstract: This study aimed to investigate coordinated actions built between Mbya-Guarani and non-indigenous children during free play activities. 21 Mbya-Guarani and 61 non-indigenous children participated in two “Encounters for Play,” a project constructed by the Indigenous Network and Mbya-Guarani communities. We recorded children’s social interactions during the free playtimes, selected the first and last 10 minutes of each encounter: (1) Performed scans every 30s registering children who were playing together; (2) Applied Social Network Analysis to explore children’s association pattern on each encounter; (3) Performed a focal continuous transcription of each child present in the interethnic clusters using an ethogram. Our results show free play was effective in promoting coordinated actions between children up to eight years old, in mixed age clusters. The “Encounters for Play” activities demonstrated the ability to mitigate the avoidance of ethnic groups in children, displaying potential as an educational intervention.

Published: November 2024

Abstract: Attention-deficit/hyperactivity disorder (ADHD) impacts individuals’ adaptive functioning from childhood through adulthood. The first-line treatment for adults with ADHD is pharmacological intervention, with cognitive-behavioral therapy (CBT) also being recommended. However, CBT efficacy remains under-researched in this population. We conducted a systematic review of randomized clinical trials to investigate the effectiveness of CBT in improving the core ADHD symptoms in adults. Data were extracted following PRISMA guidelines, including studies published from January 2012 to August 2022. We performed scientometric and descriptive analyses, finding that CBT improved aspects related to the disorder’s core symptoms and individuals’ daily functioning. Future research is recommended to delve deeper into the efficacy of CBT, aiding in understanding the cognitive and behavioral processes influencing the expression of core symptoms of the disorder.

Resumo Em diálogo com os estudos sociais da ciência, discutimos as implicações morais e políticas da regulação e normatização de corpos infantis. A partir da audiência pública “Infância plena”, realizada em 2023 no Brasil, que reuniu diferentes atores sociais para discutir as consequências dos procedimentos de “redesignação sexual” em crianças transexuais, nos debruçamos sobre o discurso da especialista convidada para analisar como as “evidências científicas” foram mobilizadas para reafirmar a cisgeneridade, em nome da “proteção à infância”. É perceptível que, aquém de uma agenda de direitos tão necessária às infâncias negligenciadas pelo Estado, esta audiência reafirmou o poder tutelar vigente no país e a (des)proteção às infâncias trans. O discurso “científico” evocado reforçou a patologização da transexualidade e uma agenda antitrans no Brasil.

A filosofia do direito como filosofia projetual: a crítica jusfilosófica diante da crise do pensamento utópico
Authors: Santos Igor Moraes
Published: November 2024

Resumo A crítica jusfilosófica contemporânea tem exercitado sobretudo uma dimensão negativa, deixando de apresentar uma dimensão positiva, propositiva, que oferte o novo, tão necessário em tempos de crise do pensamento utópico e de suposta ausência de alternativas. Propõe-se, então, reavaliar como a filosofia do direito, na condição de filosofia prática, ao tematizar o agir, prescreve e oferece possibilidades de futuro. Para tanto, examinar-se-á a conjetura, em Reale, e a imaginação institucional, em Unger, extraindo-lhes elementos para repropor a jusfilosofia como pensamento projetual. Concluir-se-á que a filosofia do direito possui potencialidades imaginativas que podem ser aproveitadas a fim de conceber projetos de novas normas, instituições e sociedades, reaproximando pensamento e ação.
“La principal barrera para alcanzar el bienestar en salud de la comunidad trans-travesti es la patologización de nuestras corporalidades”. Entrevista a Anastasia María Benavente sobre el derecho a la salud de las personas trans
Authors: Benavente Anastasia María , Grandón Valenzuela Débora
Published: November 2024

Resumen La experiencia de la salud y bienestar de las personas trans ha sido escasamente investigada en terapia ocupacional. Para ahondar en esta problemática desde la perspectiva situada y protagónica de la comunidad, presentamos una entrevista a Anastasia María Benavente, investigadora, profesora, actriz, performer y activista de la comunidad travesti-trans. A lo largo de este texto, se recorren los avances y tensiones legislativas que las leyes de identidad de género han tenido en Chile, en comparación con la experiencia argentina. Se describe la violencia estructural que vivencian las personas trans, y cómo esta produce desigualdades en el acceso al trabajo, la salud y el bienestar, disminuyendo inclusive su expectativa de vida respecto de las personas cisgénero. También, se abordan las barreras que la comunidad trans-travesti experimenta en la atención de salud, relevando cómo la escasa formación en materia de género por parte de las y los profesionales de la salud reproduce la patologización de las corporalidades trans. Finalmente, la entrevistada comparte algunos de los avances de su tesis doctoral evidenciando cómo la comunidad trans-travesti ha tramado históricamente estrategias y saberes colectivos de supervivencia, lo que insta a la terapia ocupacional a sostener una mirada crítica tanto sobre las relaciones estructurales de desigualdad, así como sobre la agencia de las comunidades.
My word is my curse: Cavell’s reading of Austin after Derrida
Authors: Senatore Mauro
Published: November 2024

Abstract In his influential essay “Signature, Event, Context” (1972), Derrida puts forward a shocking appraisal of Austin’s ground-breaking doctrine of the performative. He interprets Austin’s treatment of the failures that may affect performative utterances as the repetition of the traditional philosophical treatment of the negative. In this article, I will focus on an overlooked development of Derrida’s encounter with Austin’s text, namely, the response to the aforementioned appraisal that Stanley Cavell offers in his A Pitch of Philosophy (1994). I will show that, after and pace Derrida, Cavell reads Austin’s doctrine of the performative as the exploration of the tragic dimension that is peculiar to performative utterances and consists in the terrifying risk of unintelligibility. To this end, I will examine Cavell’s alternative interpretation of Austin’s treatment of the failures that concern actions and utterances in general, and his unpacking of Austin’s anti-moralist motto “my word is my bond” into the tragic “my word is my curse.” In particular, I will cast light on Cavell’s understanding of the relation between meaning and intention, as alternative to Derrida’s, that underpins his overall interpretation of Austin’s doctrine.
Humanismo nuevo y “NosOtros” planetario: nota sobre los desafíos antropológicos del siglo XXI
Authors: Ponzio Paolo
Published: November 2024

Resumen El presente articulo quiere desarrollar la problemática del “nuevo humanismo” desde una perspectiva de transición de época, de ruptura dramática de paradigmas, poniendo el enfoque en un horizonte político-cultural y educativo. Esclareciendo que hablando de conceptos como, humanismo, post-humanismo y deshumanización, siempre es necesario tener en cuenta sea la matiz tecno-antropológica, sea aquella ético-política, si introduce la idea de un ser humano planetario - a través el recurso al pensamiento de Ernesto Balducci - que en cuanto “homo absconditus” pueda conseguir una nueva identidad, una nueva conciencia cósmica a través de la toma de conciencia de una interdependencia entre los seres humanos y la biosfera en su relación recíproca.
QCA e Process Tracing: conectando Ciência Política e História
Authors: Perissinotto Renato
Published: November 2024

Resumo Houve um tempo na Ciência Política brasileira em que análises históricas eram usuais. Os temas então estudados eram diversos e fundamentais para a compreensão do país e de sua política. Pesquisas com perfil similar desapareceram deste campo disciplinar. Diríamos hoje, como havíamos dito há alguns anos, que a Ciência Política brasileira é essencialmente “presentista” e pouco espaço concede, se é que algum, ao contexto histórico como fator explicativo. Não pretendemos identificar as causas dessa mudança, muito provavelmente vinculadas ao predomínio de um tipo de pesquisa “centrada em variáveis”. Nosso objetivo é discutir qual poderia ser o lugar do conhecimento histórico na Ciência Política e defender um retorno à história que seja condizente com as pretensões teorizantes da disciplina. Acreditamos que isso é possível por meio de duas ferramentas cada vez mais utilizadas na Ciência Política: a Qualitative Comparative Analysis (QCA) e o Process Tracing (PT).
