Authors: Coelho Weldma Karlla , Araujo Laryssa Gomes de , Caminha Maria de Fátima Costa , Falbo Ana Rodrigues
Published: September 2024

ABSTRACT Introduction: Problem-Based Learning occurs through work in small groups, facilitated by tutors, and everyone is expected to contribute to the achievement of the learning objectives. The presence of a dominant profile student could lead to some imbalance in the group dynamics. Objective: to understand, from the perspective of collaborative learning, the meanings attributed by tutors and students to the presence of the dominant profile student in the tutorial group. Methods: two qualitative studies with tutors and students were conducted at a university in northeastern Brazil. The first aimed to understand the tutor’s perception of the presence of the dominant student in the tutorial group. Semi-structured interviews were used to collect information. The population consisted of tutors from the physiotherapy undergraduate course with more than two years facilitating tutorial groups. The second study aimed to understand the meanings attributed by students about the presence of the dominance profile in tutoring. Information was collected by focus group. The study population consisted of medical students from the first four years of the course. The process of analysis and interpretation was anchored in the theoretical assumptions of collaborative learning, which also served as a reference for the development of the interviews and focus group scripts. Bardin’s content analysis technique was adopted. The studies were approved by the Research Ethics Committee, CAAE: 26191119.5.0000.5569 and CAAE: 38005320.5.0000.5569. Results: tutors and students highlighted the diversity within the dominance profile. They characterized the student with this profile as collaborative, participatory and prepared. They also pointed out characteristics of impatience, difficulty in listening and accepting arguments contrary to their own. In addition, they reported intrusive behavior, silencing and limiting the participation of others. The tutors reinforced the difficulty in dealing with the dominant student, especially when giving feedback. The students reported that tutors, when facing the dominant student, did not perceive the lack of collaboration in the group and were insecure to intervene. Conclusion: the students expressed embarrassment and insecurity when faced with presence of the dominant student, leading to losses in the construction of group knowledge and individual performance, as well as disappointment in relation to the tutor’s performance. The tutors showed they recognize subtleties within the dominance profile, despite difficulties in adequately intervening.

Published: September 2024

RESUMO O presente artigo apresenta um panorama discursivo que busca apresentar à pessoa leitora um cenário possível e emergente na busca pela construção de um contexto epistêmico-político interseccional na Biblioteconomia brasileira. Tem como objetivo apresentar a representatividade política social e informacional de Audre Lorde nos movimentos sociais, destacando a forma como se constroem as narrativas alinhados aos marcadores sociais apontados, na Biblioteconomia brasileira. Como aspectos metodológicos deste estudo, desenvolvemos uma pesquisa bibliográfica, de caráter documental e exploratório, acessando produções de Audre Lorde e outras intelectuais negras interseccionais, além de estudos produzidos na Biblioteconomia sobre classe, raça e gênero. Por fim, apontamos que na Biblioteconomia, a busca pelo fortalecimento de novas discussões teóricas é um exemplo da necessidade do uso da interseccionalidade enquanto ferramenta analítica, visto que a hegemonia de certas teorias na formação da pessoa bibliotecária contribui/contribuiu para o crescente das desigualdades sociais, perpetuando a ausência de discussões interseccionais na prática da pessoa bibliotecária.

Published: September 2024

ABSTRACT Guava decline is a complex disease caused by the interaction between Meloidogyne enterolobii and Neocosmospora falciformis (Syn.: Fusarium solani). Thus, selecting M. enterolobii-resistant genotypes within the genus Psidium is essential for controlling this disease, and developing a resistant cultivar of Psidium guajava could significantly impact this issue. Thus, the objective of this study was to assess the response of the guava plants of the cultivar Paluma to different densities of M. enterolobii inoculum. Guava seedlings were inoculated with 500, 1,000, 5,000, 10,000, and 20,000 eggs + second-stage juveniles (J2) of M. enterolobii per plant. Root and shoot fresh weights, shoot dry weight, root length, plant height, and stem base diameter were evaluated at 70 and 135 days after inoculation (DAI). Total number of M. enterolobii eggs + J2 in the root system and nematode reproduction factor nematode were assessed. Nematode multiplication in roots was not proportional to increases in initial inoculum density; thus, the best plant responses to nematode multiplication in the evaluated cultivar were found for the lowest tested densities. The reproduction factor decreased as the inoculum density was increased, at both evaluations (70 and 135 DAI).

Published: September 2024

ABSTRACT Guava is a highly important fruit crop worldwide; however, a severe phytosanitary problem caused by the parasitism of Meloidogyne enterolobii has been limiting guava yields in Brazil and in several countries. The incidence of the nematode M. enterolobii results in significant decreases in yield, often resulting in plant death in the medium term. Considering a contribution to control tools, the objective of this study was to assess the resistance of 37 accessions of Psidium guajava grown in a greenhouse to M. enterolobii. Seedlings from seeds of each accession were inoculated with 4,000 eggs of M. enterolobii when they were at the three- to six-leaf stage, in two experiments. The root system of each plant was collected at 135 days after inoculation for extracting nematode eggs. The eggs were counted in three aliquots of 1 mL plant-1, and the obtained data were subjected to analysis of variance, which showed significant differences among accessions and among plants of the same accession. Accessions were classified regarding resistance based on the reproduction factor (RF = Pf / Pi = 4,000). The P. guajava germplasm studied showed a significant variability in responses to M. enterolobii; resistant plants were identified for accessions A08, A15, A26, A13, and A30A in Experiment I and for accessions A31, A11, A16, A30A, GF3, and A08 in Experiment II; the accessions A08 and A30A stood out by presenting resistant plants in both experiments.

Published: September 2024

ABSTRACT The land use changes and different management forms promote modifications in soil organic matter (SOM), which imply the yield and sustainability of agricultural systems. SOM provides essential elements for plants, such as Nitrogen (N), one of its main constituents, and is also an indicator of soil quality. This study aimed to evaluate the dynamics of N levels and stocks in the soil of Plinthosol in the state of Tocantins, Brazil, under different uses (eucalyptus, corn, and pasture) compared to a natural ecosystem of Cerrado sensu stricto. Therefore, six trenches were opened in each study area to collect soil samples at 0-10, 10-20, 20-30, 30-40, and 40-50 cm soil layers, determining the contents and stocks (0-50 cm) of total N in the soil by dry combustion. The means were compared by the Tukey test at a 5% error probability level. N-S contents and stocks of the evaluated systems did not differ statistically from the reference area, except the eucalyptus area, which presented a higher average content, specifically in the 0-10 cm layer, and a higher average stock, considering the entire layer evaluated (0- 50cm). N-S stocks decreased in the following order across different land uses: eucalyptus > corn = pasture = Cerrado, probably indicating the effectiveness of the arboreal component in incorporating N-S as well as the importance of adopting conservation management practices that prioritize greater input and stabilization of organic matter in the soil.

Published: September 2024

ABSTRACT The present study evaluated the potential use of fish farming effluent incorporated into the standard nutrient solution and recirculation time on gas exchange and macro and micronutrient contents of watercress in a hydroponic system. The study was conducted in randomized blocks, in a split-plot scheme with 4 replicates, in two experiments carried out in spring and summer seasons. Plots were composed of different proportions of nutrient solution (NS) and fish farming effluent (FFE): S1 (0% NS and 100% FFE), S2 (25% NS and 75% FFE), S3 (50% NS and 50% FFE), S4 (75% NS and 25% FFE), and S5 (100% NS and 0% FFE). Subplots consisted of two solution recirculation times (Time 1 – T1: 15 for 15 min and Time 2 – T2: 15 for 30 min), totaling 40 experimental plots. Net photosynthesis, stomatal conductance, transpiration, substomatal CO2 concentration, SPAD index, and macro and micronutrient contents were evaluated. Net photosynthesis showed a quadratic fit in both cultivation cycles, with maximum values observed with use of 86.0% NS (spring) and 64.9% NS (summer). Leaf N and P contents indicate that the use of approximately 70% NS can be considered satisfactory, as it promoted the highest values of these macronutrients. Using fish farming effluent can enable the production of watercress in hydroponic systems, influencing the nutritional status of the crop.

ABSTRACT Pak choi is a leafy vegetable rich in important bioactives for human health. As this vegetable is cultivated predominantly in Europe and Asia, there is little information about it in the Brazilian literature. The aim of this study was to evaluate the production and quality of pak choi cultivated in hydroponic systems using nutrient solutions of different electrical conductivities. An experiment was set up following a randomized block design, in a 2 × 5 factorial scheme, with two hydroponic systems (NFT and Semi-hydroponic) and five levels of electrical conductivity (1.0, 2.0, 3.0, 4.0 and 5.0 dS m-1). The plants were harvested 35 days after transplanting and evaluated for the following variables: plant height, number of leaves, stem diameter, leaf area, shoot fresh and dry mass, leaf succulence, specific leaf area, petiole firmness, juice pH and soluble solids. Growth and quality variables were affected by the interaction between EC levels and hydroponic systems. The semi-hydroponic system promoted the greatest development of pak choi plants and greater tolerance to salinity. Plants cultivated in the NFT system had a lower nutritional requirement to reach maximum growth. Increase in nutrient solution EC did not affect the visual quality of pak choi, but reduced the physicochemical quality of its leaves.

ABSTRACT Diversifying cultivars and intercropping with lemongrass can innovative strategies for banana growers to enhance the variety, profitability and sustainability of their orchards and to adapt to climate change. This study took place in the state of São Paulo, a subtropical region of southeastern Brazil and assessed the duration of the cropping cycles, growth and yield performance, and leaf nutritional content of banana cultivars BRS FHIA Maravilha, SCS 451 Prata Catarina, BRS Pacoua and Prata Anã when intercropped with lemongrass. The field experiment spanned two consecutive growing seasons. The growth, yield and nutrient content in the leaves of banana cultivars exhibited similar performance in both monoculture and intercropping with lemongrass. A shorter cycle was observed only in the first harvest with the lemongrass intercrop. The Prata Anã cultivar stood out for its earlier cycle, lower plant height and higher average yield per year. These findings are valuable for planning cultivar diversification in new orchards, exploring the potential for intercropping with lemongrass, and identifying the genotypes and cropping systems that are better suited to adverse climatic conditions.

ABSTRACT The classification based on morphological descriptors in lettuce is considered a complex activity and proves to be efficient for studying phenotypic characteristics. Therefore, the objective of this study was to analyze the biofortified lettuce germplasm bank at the Universidade Federal de Uberlândia using both conventional morphological descriptors and artificial neural networks. The experiment was conducted in the field. The experimental design employed was a randomized complete block design, consisting of 14 treatments (11 genotypes of mini lettuce, and the cultivars Purpurita, UDI 10.000, and Pira 72) with four replications. Nine morphological descriptors were evaluated. Following the data acquisition, dissimilarity matrix analyses, principal component analysis, dendrogram construction, and artificial neural network (ANN) analyses were performed. The genotypes exhibited phenotypic variability when compared to the parental strains UDI 10.000 and Pira 72. The purple color of the leaves and anthocyanin presence across the entire leaf surface were predominant among the genotypes. Descriptors such as leaf intensity and color, as well as anthocyanin intensity, coloration, and distribution, were the most influential in assessing genetic variability. The Self-Organizing Map (SOM) demonstrated greater sensitivity in discriminating between genotypes compared to the Unweighted Pair Group Method with Arithmetic Mean (UPGMA). While the UPGMA clustering method grouped genotypes into three clusters, the SOM method grouped into five clusters. The use of genetic distance analyses and SOM dendrogram proved to be effective in selecting individuals UFU 215#1, UFU 215#2, UFU 215#6, UFU 215#10, and UFU 215#13, which are clustered with the cultivar UFU Mini Biofort.

ABSTRACT Salt stress is one of the main abiotic factors responsible for limiting agricultural production worldwide, especially in regions with a semi-arid climate, where climatic conditions intensify the effect of salts on plants. The objective of this study was to evaluate the mineral composition of sour passion fruit plants grown under irrigation with saline water and potassium fertilization in a semi-arid region of Brazil. The experiment was carried out under field conditions in São Domingos, PB, Brazil. A randomized block design was adopted, in a 5 × 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and four potassium doses - KD (60, 80, 100 and 120% of the K2O recommendation) with 3 replicates. There was an increase in sodium and chloride contents in the stem and leaves of sour passion fruit plants with the increase in ECw levels. Fertilization with 120% of the K2O recommendation associated with irrigation using water with EC of up to 1.1 and 1.6 dS m-1 increased potassium content in the stem and leaves and leaf nitrogen content, respectively, in ‘BRS Sol do Cerrado’ sour passion fruit plants. Fertilization with 60% of the K2O recommendation increased phosphorus content in the leaves of sour passion fruit plants under water salinity of up to 2.2 dS m-1. In the leaves, nutrient contents varied according to the order of concentration N>Cl>P>Na>K, while in the stem the order was N>Cl>P>Na>K, at 160 days after transplanting.
Intercropping systems of corn and forage grasses with application of low mesotrione herbicide rates
Authors: Correia Núbia M. , Lenza Ramon A. do B.
Published: September 2024

ABSTRACT Sowing forage grass species of the genera Urochloa and Panicum simultaneously with corn can hinder crop grain yield, requiring the application of low herbicide rates for suppressing their growth and preventing potential competition with corn plants. Therefore, the objective of this study was to evaluate the use of low rates of the herbicide mesotrione for inhibiting the growth of forage grass species (Urochloa ruziziensis and Panicum maximum, cultivars BRS Tamani and BRS Zuri) sown simultaneously with corn crop, as well as the recovery capacity of these grasses. Two experiments were installed, as first and second crop seasons, in a randomized experimental block design with four replications, using a 3×4 factorial arrangement and three control treatments with corn alone. Each of the three forage grasses was sown simultaneously with corn and subjected to post-emergence application of four mesotrione rates (0, 48, 96, and 144 g ha-1) with atrazine (1.25 kg ha-1). Weeds, forage grasses, and corn plants were evaluated. BRS Tamani was the most tolerant forage to mesotrione, while BRS Zuri was the most sensitive. The application of mesotrione + atrazine in the corn-forage grass intercropping system contributed to weed control. The tested forage grasses did not affect corn grain yield in the first or second crop season, even with no herbicide application.
Universal equations for rainfall distributions from SCS and Huff methods
Authors: Silveira André Luiz Lopes da
Published: September 2024

ABSTRACT The temporal distribution of design rainfall hyetographs can be obtained through various procedures. One such method involves using temporal distribution curves to disaggregate a rainfall value of longer duration into chronological values within shorter time intervals. This is demonstrated by SCS distribution curves for durations of 6 and 24 hours and the well-known Huff curves. Another approach involves deriving temporal distribution using design hyetograph calculation methods, such as the Chicago and alternating block methods, based on Intensity-Duration-Frequency (IDF) equations. This paper aims to combine these approaches and develop universal equations capable of accurately fitting smooth rainfall time distribution curves. The advantage is the replacement of tables, like SCS and Huff, with analytical equations, enhancing usability in spreadsheets. Furthermore, these universal equations can determine the temporal rainfall distribution using an IDF equation or fitting a specified design hyetograph like Euler type II. Four numerical examples are provided.
Therapeutic gardens: historical context, foundations, and landscaping

Published: September 2024

Abstract The Therapeutic Garden can be conceptualized as a designated space engineered to engender benefits on physical, psychological, cognitive, and social well-being of its users, facilitated through either passive or active engagement with nature. This review explores the therapeutic function of gardens, encompassing their historical evolution, theoretical underpinnings, concepts, benefits, uses and design guidelines. The therapeutic attributes of plants have been acknowledged since antiquity, underpinning the belief that nature constitutes a primary agent in fostering well-being. This conviction gained traction during the Middle Ages, by the cloister gardens, which sought healing through a communion with nature. Nonetheless, this relationship waned during the Renaissance, only to resurface in the 18th century within the realm of hospital architecture, underscoring the necessity of reinstating therapeutic gardens as an indispensable adjunct for healing patients. In recent times, there has been a resurgence in the quest to reconnect with nature, driven by scientific research highlighting the myriad health benefits of nature exposure, that fundamental various theories such as the Supportive Gardens Theory, Restorative Gardens, and Healing Gardens. These pioneering studies have paved the way for further research exploring the psychological, physical, and social advantages of gardens. Designs for therapeutic gardens should prioritize user needs, drawing from a multidisciplinary approach rooted in evidence-based design principles. However, specific definitions regarding their form and function remain elusive, allowing for a diversity of activities and adaptability to cater to different users.

Published: September 2024

Resumen Este artículo presenta una interpretación sobre las políticas públicas en materia de Educación para la paz. Con este propósito, a través del análisis de fuentes documentales y del contexto, inicialmente se recuerda el fundamento filosófico que da cuenta de la condición humana, en cuanto seres políticos en relación. Luego se trae a colación la teoría de las políticas públicas en general y, seguidamente, se muestra en detalle las vicisitudes de su aplicación al caso específico colombiano en materia de Educación para la paz. El texto culmina con algunas reflexiones que dan cuenta de puntos críticos, encuentros y desencuentros. De esta manera se llama la atención para que, desde una perspectiva republicana democrática, las transformaciones no dependan solamente de los movimientos de la política regular, sino que la Educación para la paz, en cuanto política pública, sea un compromiso social extenso, participativo, en el que todos confluyan como propósito común.
Training of Education professionals: political and social impacts of the relationship between mentors and mentees in postgraduate studies
Authors: Oliveira Terezinha
Published: September 2024

Abstract This article is a reflection on the close relationship between research and the training of Education professionals. Its aim is to highlight that research in postgraduate studies affects society in all aspects, especially in Basic Education. Therefore, the training of new researchers by mentors is a key component for the development of science in the country. Given this perception, the topic needs to be explored and investigated because the relationship between mentor and mentee constitutes the heart of postgraduate studies, and its outcomes impact everyone, as evidenced by the data from Inep presented in the article. It’s important to consider that postgraduate studies, by generating science and training professors in Higher Education who train new teachers, should not be overlooked. I emphasize that the presented formulations here demonstrate my position in teaching, my political action, in which historical knowledge is the vector of communal life. Therefore, it is crucial to debate the relationship between mentor and mentee in postgraduate studies because that’s where I believe essential discussions should take place.

Published: September 2024

Abstract The objective of this work was to evaluate the hygroscopic behavior and physical properties of powders from bacuri pulp freeze-dried with different drying adjuvants. Three samples were prepared by adding the maltodextrin, gum Arabic, and albumin adjuvants, at a concentration of 20% (w/w), to the pulp. The powders were analyzed for moisture content, hygroscopicity, and particle morphology. The adsorption isotherms were obtained using the models of Brunauer-Emmett-Teller (BET), Guggehneim-Anderson-de Bôer (GAB), Henderson, and Oswin at the temperatures of 25 and 40ºC. Moisture contents ranged from 2.12 to 2.90%, and the lowest value was observed for the powder containing albumin. Hygroscopicity varied from 3.64 to 6.02%, with the lowest value for the powder containing maltodextrin. The powder particles showed non-spherical and irregular shapes, being more agglomerated in the powder with maltodextrin. For the isotherm, the best fit was obtained with the BET model and a type-III behavior was observed, which is typical of foods rich in soluble sugars. Therefore, the adjuvants contribute to the physicochemical properties of the powders, making them less hygroscopic and with irregular-shaped particles.

Shaping Sustainable Bioplastics: Illuminating Chlorella sp. Growth with Light Variations and NPK Levels
Authors: Wong Y. C. , Marisaa C.
Published: September 2024

this study delved into the exploration of a biodegradable alternative to synthetic plastics through the production of biodegradable bioplastics derived from microalgae. The investigation suggests that utilizing Chlorella sp. as a viable source for sustainable biomass in bioplastic creation holds promise due to the convenience of microalgae cultivation and its rapid growth rate. However, the large-scale cultivation of microalgae requires a considerable amount of nutrients, posing challenges to its economic viability. To address this hurdle, it becomes imperative to prioritize the enhancement of growth parameters for microalgae development. This study endeavors to identify the optimal NPK (nitrogen, phosphorus, and potassium) concentration and light spectrum for Chlorella sp. using a cost-effective NPK fertilizer medium. Various combinations of light spectra and NPK levels were examined to optimize growth conditions. Cultures of Chlorella sp. were subjected to red (660 nm), blue (460 nm), and white light (380 ~ 760 nm) which acted as experimental control over a span of 10 days. Among these, blue light yielded the highest optical density at 0.687, while red light exhibited the lowest optical density at 0.349. The findings underscore that the quantity of NPK fertilizer employed as a growth medium correlate directly with the observed cellular growth in Chlorella sp. cultures. The study also encompassed tensile strength and biodegradability assessments to characterize the resulting bioplastics. Tensile tests disclosed that bioplastics synthesized with sorbitol displayed a lower tensile strength of 0.106 MPa, in contrast to bioplastics containing both sorbitol and chitosan, which demonstrated a tensile strength of 0.167 MPa. In conclusion, both the appropriate light wavelengths and NPK nutrients emerge as pivotal factors influencing photosynthesis and the growth of photoautotrophic microalgae. The overarching objective of this research was achieved by successfully producing bioplastics using microalgae biomass residue cultivated under optimized parameters.

Published: September 2024

The aim of this study was to analyse how body measurements, live weight and age in young Limousin bulls are interrelated, and what ratio of the phenotype variance can be explained by a group of them, so what traits should be considered in early selection.
Body measures of 8-9 months old Limousin young bulls (n=610) in two consecutive years from 32 Hungarian farms were registered, and their covariance structure was studied by principal component analysis. Two components were defined, explaining 71.58% of the total variance. The first component was composed of live weight and body measures; the second component contained age. Live weight, withers’ height and hip height measures had highly definitive effect in the first component. Length of back, width at shoulders, and width at hip bone measurements had lower, but still significant effects. Eigenvalue of the first component had been very high, with 58.36% eigenvalue variance. Only effect of age proved to be highly significant in the second component, with an eigenvalue variance 13.22%. As age contributes less, if correction is needed for transforming results of individuals comparable, then it is advised to be based on live weight. Registered body measurements could be considered together in selection decisions, not needless to take all separately.

Published: September 2024

This article is devoted to the study of the influence of the technological parameters of spraying, in particular the gaseous medium, on the physical and mechanical properties and corrosion resistance of gas-thermal metallization coatings. To protect the housings of submersible electric motors (PAD) in oil and gas wells, the method of electric arc metallization (EDM) has become widespread, due to the high level of physical and mechanical properties of the resulting gas-thermal metallization coating, high productivity and cost-effectiveness of the process, as well as the mobility of equipment. Despite the effectiveness of this method of protection, it does not exclude the occurrence of corrosion processes in the metal of the PAD body. In this regard, research aimed at increasing the operational life of the metallization coating is relevant and promising.The article considers the theoretical aspects of the influence of the technological parameters of the spraying process on the properties of the metallization coating. The effect of the sputtering gas medium on the physical and mechanical properties and corrosion resistance of metallization coatings has been experimentally investigated. Comparative tests and studies of gas-thermal metallization chromium-nickel coatings applied by the EDM method in an air environment and in an argon environment have been carried out. The main trends and features of the formation of metallization chromium-nickel coatings applied by the EDM method and the effect of the application mode, in particular the technological gas spraying medium on the microstructure studied on metallographic grinds using a scanning electron microscope with an attachment for energy dispersion analysis; microhardness determined by the Vickers method are determined; The wear resistance is determined by abrasive wear during friction against non-rigidly fixed abrasive particles and the corrosion resistance of the resulting coatings, determined by autoclave tests during exposure in a simulated environment containing corrosive components.The study of the influence of certain technological parameters of spraying of gas-thermal metallization coatings, including the gas medium, on the properties of the coatings obtained is a fairly promising task aimed at increasing the operational life of the metallization coating, which in the future will reduce the cases of premature failure of oilfield equipment.

The study examined the possibility of monitoring and identifying anomalies in the combustion process based on the patterns of flame visualization in the combustion space. Experimental studies were carried out on a semi-industrial stand to study the combustion of pulverized coal. Combustion images were classified using a deep learning algorithm for a finite number of corresponding excess air coefficients (α). Based on the excess air coefficient, we divided combustion modes into three main classes: efficient, ineffective and anomalous. This type of classification provides a simple approach to optimize the combustion process and alert the system in the event of critical events. The resulting model classified combustion modes with an accuracy in the range of 87–91 %.
The Topic of Snakes in Teacher Training

Published: September 2024

Perceptions about snakes range from fascination to phobia, making them a relevant topic for discussion in environmental issues of basic education. This topic requires a safe and empathetic approach by teachers. Considering that environmental education is a curriculum guideline to be developed by teachers from different areas of knowledge, we investigated some factors that may influence the attitude of undergraduate students in teaching degrees when addressing this topic in an extracurricular activity.. We evaluated 120 future teachers through an online survey regarding their area of expertise, training stage, values, and emotions or feelings towards professional behavior when encountering a snake during an environmental education activity in a non-formal setting. The results indicate that only “fear” and “scientist” values interfered with the performance of future teachers. We propose that environmental education involving stigmatized animals be emphasized in teaching degrees to expand positive didactic experiences, minimize prejudicesand fears, and facilitate the reconstruction and dissemination of knowledge through the conscious action of future educators.

In the lead up to the issue of Logos dedicated to the debates on the Gabriel Tupinamba’s Desire of Psychoanalysis the guest editor addresses the question of the problematic existence of psychoanalytic institutions. It is assumed that psychoanalysts take advantage of the opportunities of being in professional communities in order to expand their experience and acquire various beneficial influences on their practice. In reality, at the same time, institutional spaces (psychoanalytic associations, schools, independent associations of specialists) act as a small political stage, supported on which an unprecedented level of conflict is supported by the institutional management regime itself. In fact, this leads to the fact that institutional spaces are used by analysts for mental reactions, which are forbidden for them both in the clinic and in scientific interaction with representatives of other disciplines. Psychoanalysts themselves refrain from any problematization of these effects, and the functioning of the analyst in the institutions that constitute the official façade of the analytic discipline, paradoxically continues to be the most obscure side of what is happening in psychoanalysis. This internal silence is supported from the outside also by intellectuals who resort to the use of psychoanalytic knowledge to produce their own theoretical constructions. Neither the operation of political concepts, nor the general socio-critical background in which such an intellectual usually operates, leads to the questioning of the circumstances of the institutional functioning of psychoanalysis. Instead, non-clinical researchers do the opposite, borrowing the theory and apparatus of psychoanalysis in order to justify the project of a certain political future for “society as a whole.” It is in this vein that a theory is produced that juxtaposes psychoanalysis with philosophical thought, beginning with the main representatives of Freudo-Marxism and ending with the modern “Lacanian left.” Tupinamba’s work, which focuses exclusively on the organization of psychoanalytic communities, is a rare exception to the prevailing pattern. By raising the issue of the institutional functioning of psychoanalysts as urgent, Tupinamba makes an appropriate social and logical turn, correcting the one-sided exploitation of psychoanalytic theory by philosophy and at the same time allowing to break the regime of silence about what is happening on the psychoanalytic stage itself.
Lacanian Revolutions (book excerpt)
Authors:   Alameda Institute, Rio de Janeiro, Brazil, Tupinambá Gabriel
Published: September 2024

Gabriel Tupinambá’s Desire for Psychoanalysis proposes thinking about psychoanalysis in a way that has never been done before — as a scene whose clinical and conceptual significance must for the first time yield to the institutional clashes that take place on it. The development of a critical theory of psychoanalytic institutions is made possible by events that have made the institutional register, after the death of Jacques Lacan, generate events that go beyond questions of internal governance in the communities that Lacan inherited. Tupinamba emphasizes that it is in post- Lacanian analysis that elements of crisis institutional intervention come to the fore, implying control over the “political sanity” of psychoanalysts, as well as the persecution that the more radical and autonomous wing of Lacanian researchers is constantly subjected to from the institutional center coordinated by Jacques-Allain Miller, holder of the monopoly on “clinical thought.” The illumination of these processes also allows us to ask other questions that relate to the circumstances usually presented in psychoanalysis as its natural historical coordinates. We are referring first of all to the inequality of those undergoing analysis in terms of their ability to pay for it, to the pathological insularity of the analytic communities themselves, leading to the maintenance in them of an illusory regime of depoliticization against the background of external socio-political crises. At the same time, the effects of the latter are artificially normalized by the clinic and institutions of analysis in the name of maintaining the stability of psychoanalytic practice. The Desire for Psychoanalysis calls for an end to the internal justification of these circumstances, calling into question the very possibility of “continuing with Lacan” claimed by his institutional heirs. Instead, Tupinamba proposes to reassess the Lacanian legacy itself, both in its institutional domain and in the part of the theory Lacan created, suggesting a problematic relationship between the conceptual foundations of Lacanian thought and the shape of the clinical community he created shortly before his death.
Pure and Applied Mathematics Though the David Bloor’s “Strong Programme”
Authors:   Lomonosov Moscow State University (MSU), Russia, Sokuler Zinaida
Published: September 2024

David Bloor’s work shows the insightfulness of applied mathematics for the philosophy of mathematics and at the same time provides convincing historical material for his “strong programme” in the sociology of science. Bloor insists that “scientific rationality” is a social institution connected to other social institutions of a given society and therefore there is no “Manichean antithesis” between the rational and the social. The very purity and rigor of mathematics, which has fascinated philosophers since Plato, is a social institution. The disciplinary division of mathematics into pure and applied one is also such an institution. According to Bloor’s sociological understanding, mathematical rigor results from critical discussion within an interacting community of acknowledged experts. For Bloor, equations are tools for solving a given set of problems; their usefulness is assessed in the social interaction of experts within specific social institutions. Institutions can both facilitate and inhibit the success of scientists. Here “success” means the achievement or non-achievement of objectives. In an extensive historical and scientific study, The Enigma of the Aerofoil, Bloor reconstructs the development of aerodynamics in Great Britain and Germany in the first third of the twentieth century. Aerodynamics is an experimental science in which the role of applied mathematics is very important. Scientists in Great Britain took a losing and unpromising route, whereas in Germany classical aerodynamics was developed during those years, which greatly contributed to the development of aircraft engineering. Bloor shows a difference in the methodological orientations of the British and German scientists: the former were looking for a true theory, while the latter were determined to create engineer-friendly computational tools. Bloor attributes this difference to the difference in the educational systems from which the British and the German scientists came.
Neoliberalism’s Demons: On the Political Theology of Late Capital
Authors:   North Central College (NCC), Naperville, IL, USA, Kotsko Adam
Published: September 2024

This is an abridged translation of the chapter from Adam Kotsko’s Demons of Neoliberalism: On the Political Theology of Late Capital. The author examines the politicaltheological characteristics of neoliberalism, in which the free market appears at first glance to be devoid of any external interference, but in fact turns out to be the result of a political strategy of governance, enriching elites, humiliating racial and gender minorities, and creating poor marginalized populations. Neoliberalism, according to Kotsko, is both a social order (the structure of family and sexuality, as well as the racial hierarchy) and a political order involving law and punishment, wars and international relations. Above all, however, neoliberalism is a coherent moral system that rests on a logic of constrained subjectivity (demonization), competition (in which there must be both winners and losers), and conformity at all levels, from the individual to the global. Kotsko identifies the core principles of neoliberal politics, such as demonization, criminalization, competition, and conformism, and locates their origins in the concepts of Western theology, describing neoliberalism as a holistic self-reinforcing system of political theology. All these principles are directly related to the notions of providence and free will: while granting people political freedom, the neoliberal state restricts it in every possible way, so that poverty, illness, and other failures become not just the personal, but the ideologically declared responsibility of an individual or an entire group. Neoliberalism, according to Kotsko, becomes a trap from which it is difficult to escape, because its active forces are disguised behind a selfgoverning system of universal justice, equality, and freedom of choice.
The Interpretation of Oedipus: The History of Truth and the Truth of Desire
Authors:   Saint Philaret’s Institute (SFI), Moscow, Russia, Faybyshenko Victoriya
Published: September 2024

The article examines the “interpretations of Oedipus” in the philosophical and humanitarian tradition as a paradoxical place of coincidence and non-coincidence, distinction and non-distinction between freedom and necessity, subject and structure, symbol and history, a place in which the question of the whereabouts of the questioner is raised. This place is defined by the poles of desire, knowledge, truth and power. Modern man first of all remembers Oedipus as a subject and a kind of name of desire. Through the analysis of several selected texts, we tried to see how the position of Oedipus is structured as the subject of truth, the parent and at the same time the offspring of which he is. Oedipus is interpreted as a bearer of lack (knowledge, self-awareness, etc.) and he also turns into a bearer of excess. Oedipus, who solved the riddle of man, appears as the paradigmatic bearer of human destiny and at the same time an exceptional and excluded creator of excess. He is cursed by the gods and chosen by them. Ambivalence, deployment to opposite possibilities and even the simultaneous realization of opposite possibilities create the place of Oedipus. This is the point at which a person finds his own history. The beginning of Oedipus is his end, his death is a new birth. The interpretation of Oedipus in modern times is based on the connection between subjectivity, sovereignty and transgression.
