Since the 17th century, women have been marginalized in science, with their research and discoveries often appropriated, silenced, or ignored. Despite social and legal changes in recent decades, gender inequality persists, imposing distinct professional obstacles on men and women in their scientific careers. This study analyzes gender variation in publications from the Brazilian Ecology Congress available on the website of the Brazilian Society of Ecology, covering the years 2000, 2009, and 2019. Data were collected on the type of work, the number of authors, the gender of the main author and the total authors, as well as the percentage of women in each publication, with gender identification based on the first name, according to the common sense of the Portuguese language. Out of 130 works analyzed, 97 could not have the authors' gender identified due to the absence of the first name, and among the identified authors, 60% are women. This study highlights the importance of advancing the pursuit of gender equity in academia, promoting greater visibility and equal opportunities for women in science.

3D-PRINTED AEROGELS AND SOLUTION-BLOW SPUN FIBERS MODIFIED WITH METAL-ORGANIC FRAMEWORK/MOLYBDENUM DISULFIDE FOR ADSORPTION AND PHOTODEGRADATION OF ENVIRONMENTAL CONTAMINANTS. The removal of organic contaminants from aqueous systems, such as synthetic dyes, poses a significant challenge due to the limited efficiency of conventional methods typically employed. The presence of dyes in the environment can lead to various negative impacts, as these compounds often exhibit toxicity and persistence. In this context, the development of novel and efficient methods and materials capable of not only removing but also degrading such contaminants is imperative. In this work, a material based on MOF (metal-organic framework) MIL-88A and MoS₂ was synthesized to develop an efficient photocatalyst for environmental contaminant removal. Photodegradation tests using methylene blue (MB) as a model dye, with the material in powder form, demonstrated an efficiency exceeding 90 % within 120 min. To facilitate reuse and minimize photocatalyst aggregation in solution, the MOF/MoS₂ was immobilized onto two distinct platforms: I) aerogels fabricated via 3D printing and ii) polyvinylpyrrolidone (PVP)/SiO₂ fibers produced by solution blow spinning (SBS). The 3D-printed aerogels were fabricated using gelatin, carboxymethylcellulose, and alginate, incorporating 5 % and 7.5 % by weight of MOF/MoS₂, and were designated as HD (without MOF/MoS₂), HD/MOF/MoS₂ 5 %, and HD/MOF/MoS₂ 7.5 %. Adsorption tests showed efficiencies of 16.77 %, 28.66 %, and 95.86 %, respectively. In photodegradation experiments, all aerogels achieved efficiencies exceeding 80 %. The PVP/SiO₂ fibers produced by SBS underwent thermal treatment to for partial removal of the polymeric portion before incorporating MOF/MoS₂. In MB removal tests using PVP/SiO₂/MOF/MoS₂ fibers, efficiencies greater than 90 % were observed within 48 h. Additionally, the PVP/SiO₂ fibers contributed to both adsorption and photodegradation processes, suggesting a synergistic effect. Finally, the PVP/SiO₂/MOF/MoS₂ platform demonstrated versatility in removal other dyes and the antibiotic tetracycline. Thus, the results obtained for both platforms indicate their potential for mitigating environmental contaminants.

The soil is an integral part of the earth's biosphere. On top of the soil is litter, made up of all the plant material produced by plants, whose main function is to supply the soil with nutrients. However, there are other parameters that influence the soil and should be assessed, such as pH and humidity. In this context, the following work sought to assess the influence of the litter produced in different areas of vegetation cover on different physical and chemical parameters of the soil. To this end, the Lagoa do Sino campus of the Federal University of São Carlos was chosen as the study area, where three sample areas were delimited within its boundaries: one in an agroforestry system (SAF), one in a remnant of native forest (FLO) and one of soil without defined use (SE). In order to assess the influence of leaf litter, we first sought to characterise it in terms of its productivity and moisture retention over a 10-month period, between January 2023 and October 2023, using rectangular collectors spaced in the sampling areas. At the same time, soil moisture was assessed at different depths during the same period. Subsequently, in single laboratory activities, different chemical parameters were evaluated, including organic matter (OM), hydrogen potential (pH), cation exchange capacity (CEC), specific surface area (SE) and electrical conductivity (EC). From the results generated, it was possible to see a positive relationship between litter and soil moisture, where the sample area with the highest litter productivity had a greater capacity to retain moisture over the period assessed. The native forest remnant fragment showed great potential for litter productivity, especially in months with high rainfall (February and October), while the agroforestry system fragment showed low plant material production power due to its heterogeneous forest composition. As for the chemical parameters, due to the presence of Eucalyptus trees in the remnant native forest fragment, it was possible to see a decrease in the pH of the litter when compared to the SAF sample area and an increase in the specific surface area and cation exchange capacity, demonstrating greater capacity in the native area fragment to reduce erosion processes.

The Integral Education Program (PEI) has been introducing significant changes in schools, such as the implementation of new subjects and mandatory content, such as the “Life Project”, which aims to encourage young people to reflect on their choices for the future, preparing them for challenges and the “Youth Clubs”, whose main point is to provide organization autonomy for them. Within this scenario, many students start to worry about their life projects, with some considering having professional football as such. Given this, the proposed work seeks to analyze the reasons that lead students to have professional football as a Life Project. Could it be the media appeal, the love of playing football or economic and fame issues? The qualitative research involved contact with a PEI school where students who have professional football as a Life Project were enrolled and carrying out semi-structured interviews with the students to identify the motivations for this choice. For this work, six students were interviewed, four girls and two boys, bringing to light three distinct categories, namely: a) Personal motivations and challenges, highlighting the complexity in building a Life Project in football, influencing both sporting development and the formation of a resilient and determined identity; b) Sport and education in life, revealing an interaction between school demands and sporting involvement, where personal organization and Physical Education classes are fundamental for students; c) Professional future in football and beyond, indicating that the journey in professional football is marked by challenges, expectations and choices that impact both careers and life perspectives. In conclusion, the work identifies that the choices for professional football as a Life Project among young people are influenced by personal, family and social factors.

Interest in Lepidoptera in forensic entomology has grown in recent years, reflecting the need to establish a solid knowledge base to explore their potential in this area. Forensic entomology uses the biology of insects and arthropods in criminal investigations, especially assisting in the estimation of the post-mortem interval (PMI), since insects are the first to colonize the crime scene and bodies. With scientific advances, the inclusion of Lepidoptera can improve the accuracy of criminal investigations and contribute to a more comprehensive understanding of the circumstances surrounding crimes. Therefore, the present study aimed to address the importance and relevance of moths and butterflies in forensic entomology based on published scientific works. The research was conducted based on reviews of studies published in peer-reviewed academic journals, using sources such as Google Scholar, PubMed and SciELO. The literature review revealed that these provide a comprehensive understanding of the topic, but highlights the need for further research and the development of specific methods for this group of insects. The ability of Lepidoptera to complement evidence obtained by other insects enriches forensic investigations, offering a more detailed analysis of the circumstances surrounding a crime. With scientific and technological advances, these insects have the potential to become a valuable tool in forensic entomology.

Corticosterone is a glucocorticoid hormone involved in fear and anxiety responses in threatening situations. The inhibition of its synthesis using metyrapone has been shown to reduce unconditioned defensive responses in male rats. Recent studies suggest that females may exhibit different responses from males depending on their estrous cycle phase. This study aimed to expand the understanding of corticosterone's role in unconditioned fear expression in males and females at different estrous cycle phases. A total of 111 adult Wistar rats (73 females and 38 males) were used. Fourteen days before testing, animals were habituated to the laboratory, and female estrous cycle phases were determined daily. On the test day, females were grouped into proestrus/estrus or metestrus/diestrus according to their current cycle phase. Control animals received an intraperitoneal vehicle injection, while experimental groups received metyrapone at doses of 30 or 60 mg/kg. Twenty minutes post-administration, animals underwent 5-minute behavioral assessment in the elevated plus maze (EPM), followed by 5 minutes in the open field test (OFT) after a 10-minute interval. In the EPM, metyrapone decreased rearing and increased open-arm entries in males compared to controls. In females, regardless of cycle phase, metyrapone reduced closed-arm entries and rearing. In the OFT, metyrapone increased center time and crossings in males. In proestrus/estrus females, it increased center time and peripheral crossings while reducing immobility. In metestrus/diestrus females, it increased center time but decreased rearing and immobility. These findings indicate a reduction in defensive responses in both tests, suggesting a clear anti-aversive effect. However, metyrapone also influenced overall exploratory behavior, highlighting its broader impact on locomotion and anxiety-like responses.

Conventional agricultural production is mostly environmentally degrading, which leads to negative impacts on ecosystems. Conventional production systems are one of the main threats to biodiversity, and today alternatives to more sustainable agricultural systems are needed. One alternative is agroforestry systems (AFS), since they aim to ensure a more sustainable mode of production, reconciling economic activity with the conservation and maintenance of biodiversity, while aiming at food security for the growing world population. However, the lack of studies that prove the beneficial relationship between biodiversity maintenance and agroforestry means that this system is not fully accepted by farmers. Studies on the feeding guilds of avifauna are able to generate information about a particular site, such as the occurrence of disturbances or its recovery. Considering birds as good indicators of environmental quality, this project aims to analyze the feeding guilds of avifauna that use the resources of a biodiverse agroforestry system (SAF) in southwestern São Paulo. For the elaboration of this project, a survey of the avifauna in the SAF was carried out. A total of 74 bird species were recorded, distributed among 25 families. Equitability analyses between families and between feeding guilds indicated that there were no statistically significant differences, and given the plant diversity found in the study area, both bird species with specialized diets (frugivores and insectivores) and generalist species (omnivores) were recorded, as well as species considered to be potential seed dispersers. These results suggest that the SAF can favor the enrichment of the area over time, however, it is important to consider the entire landscape, and the combination of forest fragments with the SAF can therefore enhance environmental services and increase local resilience.

The Tribe Tetrataeniini (Orthoptera, Acrididae, Leptysminae) comprises a diversity of semiaquatic grasshoppers with a wide distribution in the Neotropical region. Individuals of this group play important roles in natural and agricultural ecosystems. In Brazil, there is insufficient data to cover the vast territorial extension for delineating occurrence areas of species belonging to the Tribe Tetrataeniini. This study aims to catalog and analyze georeferenced data on Tetrataeniini species within the national territory, based on records available in scientific literature and entomological collection databases. Using QGIS software, maps were generated to highlight the spatial distribution of species, identifying potential occurrence areas for Tetrataeniini species, regions with the highest concentration of records, and knowledge gaps. This research observes that the distribution of species in this tribe is strongly associated with biomes such as the Amazon (46%) and the Atlantic Forest (33.1%), reflecting their ecological preferences and potential relationships with environmental factors. It also notes that six species (Xenismacris aetoma Roberts & Carbonell, 1980, Tetrataenia virgata (Gerstaecker, 1889), Stenopola tigris Roberts & Carbonell, 1979, Stenopola viridis Roberts, 1980, Stenopola caatingae Roberts & Carbonell, 1979, and Cornops dorsatum (Bruner, 1911)) and two subspecies (Stenopola rubrifrons mima Roberts & Carbonell, 1979, and Eumastusia koebelei koebelei (Rehn, 1909)) are endemic to Brazil. This study aims to support future research on species of the Tetrataeniini Tribe to determine the factors influencing their distribution, identify potential organisms for use as bioindicators and biological control agents in Brazil, and provide a basis for further taxonomic and ecological investigations.

The agribusiness sector, as the hegemonic agri-food system, has not been effective in combating hunger due to its dynamics, which strengthen the development of large transnational groups that control the production and commercialization of agricultural products, prioritizing the production of commodities over food. In this context, agroecology emerges as an alternative agri-food system where farmers and consumers take center stage, representing a necessary condition for transforming the current structure of the agri-food system. This transformation aims to reshape the way food is produced, distributed, and commercialized. Given this, this study aims to investigate the potentialities and challenges in ensuring food security and sovereignty in two rural settlements classified as Sustainable Development Projects (PDS): PDS Santa Helena and PDS Mário Lago, located in the municipalities of São Carlos (SP) and Ribeirão Preto (SP), respectively. These settlements implement a strategic agroecological project to improve the food and nutritional security of settled families while developing a production model distinct from the dominant sugar-alcohol agribusiness in the region. Methodologically, the investigation was structured through field research with semi-structured interviews and the application of the Brazilian Food Insecurity Scale questionnaire in both PDS Santa Helena and PDS Mário Lago settlements in São Paulo. The study concludes that, unlike the national reality, the PDS model settlements, through collective and cooperative work and agroecological production, contribute to reducing food and nutritional insecurity among settled peasant families.

O presente estudo analisa as possibilidades resumidas, e provavelmente interpretativas da ferramenta de inteligência artificial (IA) — com uso de uma plataforma de Large Language Models (LLM) — modelos de aprendizado de máquina — para explicar a reputação do Brasil no exterior, como proxy do estudo. Os dados secundários coletados foram ponderados conceitualmente, com a literatura vigente sobre gestão de marca de lugar e inteligência artificial em marketing, a partir de dois prompts (perguntas) e nove índices internacionais. Para análise dos dados, utilizou-se análise do conteúdo com consideração temática ao comparar com o estado da arte da literatura nacional e internacional. Os resultados demonstram que a análise comparativa entre os retornos da plataforma e dos índices com a literatura existente evidenciam a dicotômica reputação e a complexa imagem do Brasil em contextos globais, como aspectos políticos, econômicos, sociais e culturais. Também, nota-se a variação das posições do Brasil nos índices selecionados e pertinentes com a percepção da reputação de um país, em que as respostas geradas, apesar de estarem relacionadas com temáticas específicas presentes nos índices, não evidência que as fontes se originam da literatura científica ou de métodos sistemáticos. Este trabalho contribui para o cuidado teórico e metodológico dos pesquisadores sobre estudos sobre a marca de cidade, região ou país com uso das ferramentas de LLM e IA. Descobre-se que o aprendizado de máquina relacionado com o conhecimento científico carece, consideravelmente, das realidades ou nuances sobre o lado humano do lugar, quanto ao pensamento criativo da percepção sensorial e imaginária ao vivenciar uma cidade, região ou país, literalmente, morar, visitar, trabalhar, estudar, empreender, investir, imigrar, etc. Nesse âmbito multidimensional, reforça-se a existente e necessária proximidade teórica e prática de estudos de gestão de marca de lugar com fundamentos de Relações Internacionais.

Inflation is a phenomenon of great economic relevance, as it directly affects the population's purchasing power and macroeconomic stability. However, its impact is not homogeneous across different income brackets. Based on this premise, this study aims to analyze, in a descriptive and exploratory manner, the behavior of consumer inflation for very low-income, middle-income, and high-income families in Brazil, according to the segmentation proposed by the Institute of Applied Economic Research (IPEA). To achieve this objective, descriptive and exploratory statistics techniques were used, allowing the identification of patterns and trends in inflation behavior over the period from 2017 to 2024. The study considered the main components of the consumer basket of the different social classes, seeking to understand which groups of goods and services exert the greatest influence on the inflation perceived by each segment of the population. The results indicate that very low-income families face more volatile inflation when compared to middle- and high-income families. This greater variability is largely associated with the significant burden that items such as food and housing have on the budgets of poorer families. The increase in the prices of these essential goods has a more severe impact on this segment of the population, which allocates a greater proportion of its income to such expenses. In contrast, higher-income families tend to be less affected by variations in these segments and are more impacted by fluctuations in the prices of non-essential consumer goods and services. Thus, the study reinforces the importance of targeted public policies that take into account the heterogeneity of the inflationary impact among different social groups. Understanding the particularities of inflation for each income bracket is essential for improving inflation control strategies and for formulating measures that minimize the adverse effects on the most vulnerable segments of the population.

Intervening in the reduction of inappropriate behavior is of fundamental importance, as it allows an improvement in the quality of life of individuals and also of the people they live with in different contexts. The objective of the present research was to evaluate the effectiveness of a set of teaching procedures consisting of written instruction, video modeling and roleplay to teach teachers how to manage inappropriate behavior of their students with ASD. The study is a systematic replication of the research from the study by Guimarães et al. (2018), about managing inappropriate behavior with mothers. The research was conducted in a public school in the city located in the interior of the state of São Paulo. Three teachers who had students diagnosed with Autism Spectrum Disorder (ASD) and two students with ASD who showed inappropriate behavior participated in the research. To evaluate the effectiveness of the set of teaching procedures, the multiple baseline design between inappropriate behaviors was used. The procedure had the following phases: Baseline, Intervention, follow-up, observation of teacher-student interaction and social validity of the research. At baseline, the teachers carried out behavior management with the confederate only with written instructions and in the intervention, they carried out the same procedure together with video modeling. The target inappropriate behaviors were: CI-a) command to obtain item; CI-b) order to refuse items present in the environment; CI-c) refusal to deliver reinforcer; CI-d) demand leakage. The results obtained showed that the intervention was effective, the participating teachers achieved 100% correct answers, performing on average between two and three intervention sessions for all inappropriate behaviors, and in classroom observations, the teachers handled more than 60% of the inappropriate behaviors. . Regarding social validity, the teachers enjoyed participating in the research and considered it useful for their performance in the classroom. It is suggested for future research to expand the stage of monitoring the implementation of strategies with students with ASD and also work with each student's inappropriate behaviors.

Currently, population growth and global food production have been associated with global climate change and the scarcity of fresh water, for example. In this scenario, there is a global concern regarding the sustainable supply of protein for the coming decades. Brazil is a country with rich flora, including various edible plants with high protein content, such as Pereskia aculeata Miller, also known as ora-pro-nobis (OPN). Thus, this study aimed to extract proteins from OPN leaves and analyze them for their technological characteristics. The process began with the production of flour from OPN leaves through forced circulation. Subsequently, the centesimal composition of this material was performed using official methods, obtaining the following results: the moisture content of OPN leaves (88.2% w/w), and in the flour, lipids (5.6% w/w), proteins (9.4% w/w), ash (17.1% w/w), and total carbohydrates (20.3% w/w), all expressed on a dry basis. To optimize the protein extraction from the leaves, acid-induced precipitation experiments were conducted, varying the pH of the solution (2.0, 3.0, 3.5, and 4.0) to approach the isoelectric point of the leaf proteins, aiming to improve the extraction efficiency. After conducting the tests, the pH chosen for this process was 3.5. Finally, after obtaining the protein concentrate, protein suspensions with concentrations of 1.0% w/w (T1), 2% w/w (T2), and 4% w/w (T3) were prepared, and steady rheological tests were carried out to measure viscosity, as well as oscillatory frequency and temperature scans in the linear viscoelasticity region for all treatments. The results indicated that the fluid exhibited a Newtonian behavior, regardless of the protein concentration in suspension. A maximum viscosity of 1.378 mPa·s-1 was observed for T3. The viscous (G'') and elastic (G') moduli showed slight dependence on frequency for all treatments, with G'' > G'. In none of the protein concentrations tested was the formation of thermal or acid gels observed. Therefore, it is concluded that this study contributes to a deeper understanding of the physicochemical characteristics of the leaf and the behavior of ora-pro-nobis proteins in suspension, evaluating its potential for future applications in the food industry, highlighting a native plant protein source that can be cultivated throughout Brazil.

The construction industry in Brazil plays a significant role in economic growth and job creation in the country, contributing substantially to GDP while also promoting urban development and essential infrastructure. Additionally, the sector helps reduce the housing deficit. Given its importance, the aim of this study was to analyze the concentration of the national construction industry between 2012 and 2022. To assess market concentration in the sector, four indicators were used: market share, concentration ratio, concentration curve, and the Hirschman-Herfindahl index. In addition to these indicators, the Structure-Conduct-Performance model was also employed to provide theoretical support. Within the sector, the 50 largest companies. At the end of the analysis, the indicators showed that the sector is not highly concentrated, suggesting a lower likelihood of practices that could harm competition. However, the analysis indicated a certain stability in market shares, with few changes from year to year.

The practice of producing images of tourist destinations, in the context of mega sporting events, with the aim of increasing the international prestige of nation-states, has been recurrent since 1934, the year in which Italy, under the management of Benito Mussolini, hosted the FIFA World Cup. The political instrumentalization of major sporting events has been, since 2010, investigated under the name “sportswashing”, with the purpose of identifying and analyzing the tools used in attempts to “wash” a country’s reputation, through the mobilization of sporting appeal - via the holding of mega sporting events - and sponsorship or investment in major football clubs. Actions characterized as “sportswashing” are intended to create a façade image that, for example, in the case of Eastern countries, allows them to be promoted as a modern, liberal and Western friendly country (Martínez, 2018 apud Soyland, 2020, p. 57). The FIFA World Cup Qatar 2022 constitutes a recent experience of this practice and, with the prospect of contributing to the set of studies aimed at evaluating the perception of tourists in relation to the image of tourist destinations (Kaplanidou et al., 2016; Evers; Pineda, 2023), this research will seek to analyze the way in which Brazilian tourists perceive Qatar's tourist image, verifying the impacts and effectiveness of the country's image cleaning strategy, through the holding of a mega sporting event - FIFA World Cup Qatar 2022 - in the image perceived by these tourists. For this purpose, the image of Qatar was analyzed based on the General Model of Images in Tourism (Santana Talavera; Pinto, J. 2008 apud Pinto, R., 2012, p.567), in order to understand how the country's images were formed, following each of the seven stages of the model, and the interference they have on each other. This is an interdisciplinary research with a qualitative approach, of an exploratory and descriptive nature, with collection and analysis of primary and secondary data using bibliographical, documentary and interview research techniques, which will be carried out with a sample of approximately 0.5 % of Brazilians who participated in the mega sporting event in Qatar, in 2022. The question guide for conducting the interviews will consider, above all, the contributions of the Semiological Model, developed by MacCannel (1976 apud Pinto, 2012, p.554) and the Model Three-dimensional, presented by Echtner and Ritchie (1993 apud Pinto, 2012, p.562). The analyzes of the data collected in the interviews were carried out using the content analysis technique (Bardin, 1977). The results obtained from the research show that hosting mega-sporting events in countries with a negative or resistant image for tourism, as is the case with the country analyzed, allows tourists to visit a place they never imagined they would be, due to factors such as fear. This experience can lead, depending on their personal experiences, to more positive perceptions of the location, due to the meaning attached to the competition and the tangible and intangible changes it brings to the country.

Ceará cinema is musically rich and often it's stories are touched by what the characters listen to and sing. In Inferninho (2018), by Guto Parente and Pedro Diógenes, musical performances are crucial to demarcate affections, positions and move the events of the plot. The story almost entirely happens in a bar with live music and explores a special and dreamlike universe. This research will analyze the ways in which the musical soundtrack adheres to the narrative of Inferninho, mainly through the songs performed by Luizianne (Samya De Lavor), which are mostly from forró, but sung in different versions and in several languages. The selection of the songs was made by the Ceará native Rita de Cássia, popularly known as "the greatest forró composer" in the country. Her songs and those of other exponents of the state populate the soundtrack, marking the strength of a specific cultural scene in recent film productions in the region. Sequences considered central will be meticulously analyzed in view of the central hypothesis of the research: that musical moments articulate in a very peculiar and creative way certain narrative axes through the relationship between popular musical genres and the bodies on stage.

Since Bitcoin's emergence in 2008, its trajectory has been marked by a rapid rise, capturing the attention of investors, technology enthusiasts and even skeptics. While some see Bitcoin as a modern store of value, capable of protecting against inflation and economic uncertainties, others see it as a revolutionary asset, full of potential to generate significant returns in the short and medium term. But after all, does Bitcoin behave like a "digital gold" or like a high-risk asset, highly sensitive to fluctuations in the technology market? This study seeks to analyze this duality, investigating whether Bitcoin, despite its initial proposal of being a scarce and decentralized currency, is more similar to a safe asset, such as gold, or a volatile asset, such as the technology stocks on the Nasdaq index. For this, the period from January 2015 to January 2024 was considered, which includes moments of stability as well as turbulent scenarios, such as the Covid-19 pandemic and its global developments. Through a combination of literature review, descriptive statistics, time series decomposition and stationarity tests, the study revealed that Bitcoin, although it was conceived as a currency with store of value characteristics, presents a behavior more aligned with that of a high-risk asset. Its volatility exceeds even that of the Nasdaq index, consolidating its image as a disruptive but also unpredictable asset.
