In the search for information and ways to innovate, a good strategy is needed when navigating through tons of information to find solutions. This research explores the connection between an Inventive Problem Solving Theory technique, Wikipedia and the controlled vocabulary Medical Subject Headings. Terms from the Inventive Problem Solving Theory effects database were mapped using the Entrez system, which was developed by the National Centere for Biotechnology Information, to retrieve terms from the Medical Subject Headings. For demonstration purpose, a search was conducted on PudMed for articles related to a specific term in order to carry out the case study. The similarity between the effects database and the controlled vocabulary was calculated using the Levenshtein, Jaro-Winkler and cosine metrics. The results show that even though there is little similarity between the database and the Medical Subject Headings, the mapping can be used to analyze the PubMed results.

The number of children with Autism Spectrum Disorder (ASD) enrolled in regular Brazilian schools has significantly increased. ASD is characterized by difficulties in communication and social interaction, along with the presence of restricted and repetitive behaviors and interests. Several serious games have been developed to stimulate cognitive and social skills in people with ASD, many of which are therapeutically focused and applied in clinics. However, game design guidelines for this audience often do not consider inclusive approaches that promote collaborative learning experiences, including students with ASD. This study aims to develop a set of guidelines for designing collaborative educational games that include students with ASD. The research began with a systematic literature review to map the state of the art on the design of collaborative games specifically focused on or inclusive of people with ASD. Based on the literature review and results from Ziviani’s (2024) work on guidelines for the design of multiplayer collaborative educational games, an initial set of guidelines was developed and refined throughout the study. For the first refinements of these guidelines, a qualitative case study was conducted with a game originally designed to be collaborative, but without considering the inclusion of students with ASD. This game was applied in a municipal school with students from elementary school and high school, including students with ASD, evaluating aspects of collaboration and inclusion in the school context through direct observation, focus groups with students, and interviews with the special education expert who supervised the study. Based on the observations and suggestions collected, the first adaptation of the game was made, which was then applied in a second case study with the same students. In a focus group with special education experts, several points of uncertainty about the set of guidelines and the initial redesign of the game were discussed and refined. The study was then expanded to a third case study, in which the final version of the game, enhanced from the previous analyses, was applied to two new classes of students, including both students with and without ASD from the 6th grade of elementary school. The results demonstrated that it was possible to build a set of guidelines for designing collaborative educational games that include students with ASD. These guidelines were applied in the redesign of an inclusive collaborative game, which was used in the school context, effectively promoting interaction and collaboration among students, including those with ASD.

Bees are the main pollinators of both natural and agricultural environments, visiting approximately 90% of crop species, of which 48% are directly related to human food production. During foraging, they may collect pollen and nectar contaminated with pesticides, such as chlorantraniliprole, and transport them back to the hive. As a result, larvae are exposed to these residues, which can compromise their development and affect the formation of essential tissues, such as flight musculature. This study evaluated the effects of sublethal concentrations of chlorantraniliprole on larval development, morphometry, and flight muscle formation in Scaptotrigona postica bees. For this, larvae were exposed to five treatments: negative control (CN – food only); positive control (CP – dimethoate at 6.9 ng a.i./larva); solvent control (CA – acetone at 0.2%); chlorantraniliprole 1 (CL1 – 2.04 ng a.i./larva); and chlorantraniliprole 2 (CL2 – 0.204 ng a.i./larva). During development, key milestones were recorded: entry into the fifth instar (5°I), defecation (DF), pupae with different eye colors (PB – white; PR – pink; PM – brown; PP – black), and emergence (EM), in addition to daily monitoring of mortality. Mortality, pupation, and emergence rates were determined. Emerged bees were subjected to morphometric analyses of head width (MC) and intertegular distance (MI). Simultaneously, the flight muscles were dissected and histologically analyzed using Hematoxylin and Eosin (HE), Periodic Acid-Schiff (PAS), Methylene Blue (AM), Mallory’s Trichrome (MY), and Masson’s Trichrome (MN). Additionally, nuclear measurements of muscle cells were performed. Data normality was assessed, and ANOVA/Tukey or Kruskal-Wallis/Dunn tests were applied accordingly. The Kaplan-Meier method was used to construct the survival probability curve. Results indicated that only CP caused toxicity, presented by impacts in rates of larval mortality, pupation, and emergence, as well as in mortality during each developmental stage. Regarding developmental progression, only CL2 showed significant differences in mortality from DF to PB and from PR to PM. Although no lethal effects were observed within the same stage, mortality rate variation was noted during the 5°I period between CA and CL2. The Kaplan-Meier curve and Mantel-Cox Log-Rank test revealed a significant decrease in survival probability for larvae exposed to CL2. Morphometric analyses showed a significant increase in head width in CL1 and in intertegular distance in CL2. Histological analyses of the flight muscles revealed that both CL1 and CL2 presented focal points of tissue disorganization, presence of cytoplasmic vacuoles, and alterations in muscle fibers. Additionally, hemocytes were observed within the extracellular matrix and among muscle fibers. It is concluded that, although chlorantraniliprole did not induce larval mortality or inhibit pupation and emergence rates, it negatively influenced development and morphometric parameters. Furthermore, it caused significant damage to the formation of the flight musculature, which is essential for foraging activity.

Transport is a human right that is sometimes not respected or is simply neglected. However, guaranteeing the right to transport is one of the ways to improve the quality of life of the local population. The aim of this study is to create a methodology for identifying the accessibility of a given municipality's neighbourhoods, via bus, to the high-capacity transport hub, using easily accessible tools and quantitative data. To do this, the IBGE census sectors are used as a reference via the Geographic Information System (GIS) to identify which neighbourhoods have the best transport indicators, such as the quality of the route between the home and the bus stop - known as the first mile - and the supply of each bus stop, consisting of a simpler quantitative way of obtaining results without the need for opinion polls. The TOD (Transit Oriented Development) principle and the AHP (Analytic Hierarchy Process) methodology were used as aids. In this way, extensive qualitative surveys of users' opinions were not necessary, transforming this method into an economical, fast and effective way of measuring accessibility to public transport. A case study based on the proposed methodology was conducted in the city of Barueri-SP and the results proved useful in demonstrating the reality of accessibility in the municipality. Using an index with scores from 0 to 10, it was possible to see which sectors and neighbourhoods have the worst and best accessibility indices. Sectors close to main avenues scored well. However, gated communities were more likely to have low scores, as were peripheral neighbourhoods and other fast-growing areas where urban planning has not kept pace with expansion.

Particulate matter (PM) is an atmospheric pollutant that cause adverse health effects and Life Cycle Assessment (LCA) can support the management of PM emissions from production systems. However, there are currently no highly spatialized characterization factors (CFs) available to Brazil. Then, this study aimed to calculate CFs for PM and precursor gas emissions (NH3, SOx, NOx, VOC) for Brazil. For this, the first step was a critical review of existing models, which showed that the models with global coverage and availability of CFs for Brazil, are the most appropriate: Van Zelm et al. (2016), Fantke et al. (2017, 2019), and Oberschelp et al. (2020). However, limitations have been observed. Then, CFs for PM2.5 and precursor gases were calculated per state, mesoregion and nationally, using death results calculated using the InMAP (Intervention model for air pollution) and national emission inventories. At the state level, the highest CFs were observed for SOx (ranging from 1.18×10⁻¹ to 4.09×10⁻⁴ deaths/ton), followed by PM2.5 (9.49×10⁻² to 2.09×10⁻⁴), NH3 (6.38×10⁻² to 1.41×10⁻⁴), NOx (1.35×10⁻² to 5.42×10⁻⁴), and VOCs (2.61×10⁻³ to 1.32×10⁻⁵). The highest CFs were observed in the Southeast region, particularly in São Paulo and Rio de Janeiro. Finally, a sensitivity analysis verified the variation in results of an LCA case study concerning the choice of the characterization model, including the recommended models for Brazil and the CFs calculated in this research. The analysis used four milk production systems as a case study. Spearman’s correlation was calculated to verify the consistency of the milk systems’ ranking. Correlation analysis showed that regionalized CFs presented higher variation in the milk systems’ ranking. The CFs calculated by this research presents high correlation (> 0.9) with global CFs from other models. However, the CFs at state level resulted in low correlation (< 0.5) with all models, except with the state CFs from Oberschelp et al. (2020), the only model with CFs for Brazilian states, which presented correlation indicator equal to 0.9. The consistency between the CFs obtained in this study and those found in the literature reinforces the validity of the results and highlights the importance of using regionalized factors in LCA studies. The main limitations of the CFs are the effects equation based on data from the United States, incorporated into the global InMAP model, and the unavailability of these factors in LCA software. However, the results obtained contribute to advancing knowledge and refining the calculation of health impacts resulting from atmospheric pollutant emissions in Brazil. These contributions can benefit both academia and the business sector by providing data more aligned with national realities for impact management.

This study addresses the adaptation of the novel "Dois Irmãos" (Two Brothers) by Milton Hatoum into the miniseries directed by Luiz Fernando Carvalho and written by Maria Camargo. The analysis focuses on the differences between the novel and the series, particularly in terms of narrative, stylistic, and structural changes. Considering works and concepts from authors related to the referred field—among others, Walter Benjamin, André Bazin, and Irina Rajewsky—as premises and theoretical references, the analysis conducted in this dissertation aims to contribute to this debate, structured around an intermedia method. As a hypothesis, the research seeks to understand the adaptation, looking for common elements and the necessary narrative, visual, and structural differences that different media require. To that end, reflections on "Dois Irmãos" are presented from three perspectives (corresponding to the three chapters of this work), namely: the book by Milton Hatoum; the screenplay by Maria Camargo; and the series by Luiz Fernando Carvalho.

Software startups face challenges such as a lack of knowledge and limited resources when implementing UX practices. In relation to these practices are UX Research activities, which focus on investigating and evaluating user experience. UX Research practices can be integrated into Long-Term UX to facilitate data collection and evaluation at different stages of product or service usage over time. However, there is a scarcity of solutions that enable the integration of UX Research practices with Long-Term UX in the context of software startups. This doctoral thesis addresses the following research problem: How can professionals in software startups conduct UX Research practices integrated with Long-Term UX, given that they operate in an agile software development environment with limited resources? To answer this question, this doctoral thesis reports on the development and evaluation of the UX Research and Long-term UX in Action: Guidelines for Practice in Software Startups (UXAction-GP Framework), a theory formulated using the Socio-Technical Grounded Theory (STGT). The STGT methodology guided the execution of a systematic literature review and three distinct case studies, whose data were subjected to qualitative analysis. The emerging findings, identified codes, and categories provided the foundation for the UXAction-GP Framework. The framework’s architecture also incorporates technologies such as Generative AI and Machine Learning to train a model based on the results derived from the STGT approach. Two applications, AthenaUX and PALUX Research, were developed to explore the potential applications of the UXAction-GP Framework. Both applications underwent controlled experiments to assess user effort, frustration, and perceived achievement. The UXAction-GP Framework constitutes a solution to the identified research problem and offers substantial recommendations to support software startup professionals in conducting UX Research and Long-Term UX.

Cette thèse analyse la liberté d'expression et des coercitions qui leur sont inhérentes et que l'on observe aujourd'hui dans ce que l'on appelle les mouvements de coercition de la parole, tels que le politiquement correct, la place de la parole, la culture de l'annulation et le anticapacitisme. On analyse un corpus dont la source est diversifiée sur la base de l'hypothèse selon laquelle la liberté d'expression est le “parapluie conceptuel” des mouvements d'ajustement de la parole qui ont émergé dans les premières années du 21e siècle. Le cadre théorique méthodologique utilisé dans la recherche se fonde avant tout sur les postulats de Michel Foucault, dans ses travaux des périodes archéologique et généalogique. En outre, des publications récentes issues de domaines extérieurs à l'analyse du discours, tels que la communication et la sociologie, viennent enrichir le regard analytique, en particulier celles de S. Noble et de M. Moore, qui traitent respectivement des algorithmes racialisés et de la démocratie piratée. L'objectif de ce travail était d'analyser certains mouvements de coercition de la parole dans le contexte des réseaux sociaux tels que Facebook, Instagram et X, au regard de leurs directives de communication, ainsi que de leur opposer des énoncés régulateurs, communément identifiés comme de la censure en fonction de certaines formations discursives. Comme résultat, nous avons trouvé - dans les publications des réseaux, les projets de loi, les décrets, les directives de communication et les textes médiatiques - des aspects qui nous ont permis de comprendre l'existence d'un “dispositif” de contrôle de la parole spécifique en plein fonctionnement. Pour l'instant, ce dispositif présente les caractéristiques d'une gouvernementalité néolibérale, qui est actuellement fortement soutenue par les algorithmes qui contrôlent l'internet et, par conséquent, la parole des sujets. Au milieu du discours, on assiste à un “gouvernement du langage", à commencer par le politiquement correct, puis à un “gouvernement des corps”.

Due to the high thermomechanical loads in machining processes, proper edge preparation is essential for achieving longer tool life and good surface finishes on the produced parts. The correct choice of microgeometry can improve stress distribution, reduce heat generation, and increase edge strength. In light of this, the present work investigates the effect of edge preparation on cubic boron nitride (CBN) tools in the machining of alloy steels. Inserts with different nominal edge radii (sharp, 20 μm, 40 μm) were produced and had their microgeometry characterized. Turning tests were conducted using annealed 4340 and hardened 4140 steels, and tool wear was evaluated. The results indicate minimal chipping on sharp tools and asymmetry in the edge rounding produced by brushing. Regarding tool life tests, the sharp-edge and 20 μm radius tools showed no performance difference when machining the annealed steel. For the hardened steel, the insert with a 40 μm preparation showed the best performance, with 22% less wear compared to the other cases. It is concluded that the appropriate choice of edge microgeometry can optimize the performance of CBN tools, especially in the turning of hardened steels, providing greater efficiency and process predictability.

The adoption of practices that promote the conservation of pollinator populations, creating more friendly landscapes, has become increasingly essential in the face of the accelerated loss of biodiversity and the services associated with it. Agroforests are productive systems that can be managed with high species richness and based on practices that favor essential ecological interactions, imitating the functioning of forest ecosystems. With the objective of evaluating the adoption of pollinator-friendly practices by farmers in agroforestry management in the Ribeira Valley region, São Paulo, this study used qualitative research methodologies. In order to obtain data on livelihood assets (human, social, financial, physical and natural) and pollinator-friendly practices, semi-structured interviews were conducted with questionnaires applied to the participating farmers. Guided tours were also carried out in the agroforests to survey the species composition, with subsequent preparation of floral resource calendars, as well as direct observation of the agroecosystems and surroundings. The research was conducted with 20 family farmers who manage agroforestry in nine municipalities in the Vale do Ribeira region, São Paulo. Through the guided tour, a great wealth of ethnospecies and ethnovarieties was identified, around 350 in total, of which approximately 71% were honey-bearing. Among the agroforests, the number of managed species varied from 32 to 93, with the best coverage of flowering species being from farmers who are beekeepers. Regarding the adoption of pollinator-friendly practices, it was possible to identify that the number of practices adopted is associated with differences in assets related to livelihoods. Among the farmers with a low number of environmentally friendly practices are those with the most vulnerable livelihoods, mostly women. While the highest number of friendly practices was found among those with the best livelihood conditions, including beekeepers and farmers with more experience in agroforestry management. These results demonstrate the need to propose strategies that are thought out locally and promoted through integrated actions that combine education, infrastructure and economic incentives, seeking a common path for the conservation of biodiversity and the improvement of human well-being in agroforestry. Furthermore, based on their perceptions, farmers have identified a series of changes related to the climate, such as temperature, rainfall patterns, drought and extreme weather events, as well as changes in flowering periods and species management, which have caused reductions and losses in production. In view of the climate emergency and its impacts, especially on the most vulnerable populations, the knowledge and expertise of farmers must be considered when proposing the necessary adaptations. On this path, the possible solution involves the agroecological transition of production systems and the social construction of another relationship with Nature, based on socio-environmental justice and supported by public policies aimed at territorial development.

Memes are defined as replicating units of culture that spread through imitation, transmitting ideas, behaviors, and styles while also evolving and adapting over time. They constitute a communicational object infused with humor and criticism, frequently used as a tool for disseminating ideas, promoting debates, and reflecting on social and political issues. In light of this, the research sought to answer the following question: "What is the contribution of context to the documentary representation of memes?" To address this question, the general objective was established as discussing the role of context in the documentary representation of memes. The following specific objectives were also defined: addressing the documentary aspect of memes; analyzing the informational content in meme messages; examining processes of documentary representation of images; and validating the documentary representation of memes based on the composition of messages and their contexts. To achieve these goals, an exploratory, qualitative, and applied methodological perspective was adopted, involving a bibliographic review and the collection of memes related to the 2022 Brazilian presidential elections, analyzed using the documentary analysis method. For the validation of the proposed protocol, methods based on facet analysis and combinations with theoretical proposals from other authors were used to carry out the documentary representation of memes collected on Instagram. The results demonstrated that memes, as documents, contain multiple contextual layers that should be enriched in their documentary representation, allowing for new perspectives on the cataloging and organization of digital informational documents.

The accelerating global population growth and the burgeoning demand for products forecasted by 2030 necessitate a sustainable transformation in production and consumption patterns to avert ecological catastrophe. Recognizing this urgency, the United Nations (UN) Agenda 2030 emphasizes the need for a Bioeconomy paradigm shift, aiming to reconcile economic growth with environmental stewardship. Within this framework, Bioenergy emerges as a pivotal component, encompassing renewable energy derived from biological sources, notably solid biofuels like biomass pellets and briquettes. Latin America, endowed with abundant biomass resources, has experienced notable growth in solid biofuel production. However, the region continues to face a significant gap in methodological harmonization and policy recognition of these biofuels within carbon credit mechanisms. To address this gap, a life cycle-based methodological framework was developed to estimate the carbon intensity and decarbonization potential of solid biofuels. Inspired by Brazil’s RenovaBio program and its RenovaCalc calculator, a novel tool, namely BioCalc, was designed to quantify greenhouse gas emissions and simulate carbon credit generation for pellets and briquettes. This doctoral thesis is structured into six chapters, four of which are presented in the form of scientific articles. These chapters address global bioenergy policy analysis, comparative assessment of carbon allocation methodologies, evaluation of transportation-related emissions in export contexts, and the design and application of the BioCalc tool to estimate carbon intensity and decarbonization credit potential for solid biofuels. Modeling results demonstrate substantial variability in greenhouse gas emissions and credit generation depending on the methodological approach adopted. Estimated decarbonization potentials ranged from 3.1 to 6.2 million tCO₂e per year, with associated revenue potential between USD 35.8 million and USD 103.9 million annually, highlighting the financial significance of methodological transparency and harmonization. By combining policy analysis, life cycle modeling, and computational innovation, the work contributes a replicable and policy-relevant framework to support the quantification and market integration of solid biofuels. The outcomes provide strategic insights for incorporating pellets and briquettes into national decarbonization programs, such as RenovaBio and the Brazilian Emissions Trading System (SBCE), as well as into emerging mechanisms established under Article 6 of the Paris Agreement. More broadly, the findings underscore the crucial role of circular economy principles and methodological clarity in promoting sustainable energy transitions in Latin America and globally.

The main objective of this work is to analyze how linguistic variation was taught in classes transmitted by the Media Center (CMSP) to public schools in the state of São Paulo, during the period of emergency remote teaching (ERE), in order to verify whether the teachers adopted the theoretical-methodological perspective of Variationist and Educational Sociolinguistics regarding the teaching of linguistic variation and what was done with the students to awaken a sociolinguistic awareness. This research, with a qualitative approach and bibliographical-documentary type, is based on ideas originating in Educational Sociolinguistics (Bortoni-Ricardo, 2004, 2005; Bagno, 2007; Faraco, 2007, 2008; among other studies) and analyzes a corpus made up of class recordings from the São Paulo Education Media Center (CMSP). The research was carried out according to the following stages: 1. Bibliographic survey and literature review about teaching linguistic variation; 2. Corpus constitution (access to CMSP recordings and selection of a set of lessons broadcast during the ERE); 3. Transcription of some selected lessons; and 4. Analysis and discussion of the results. This study presents the analysis of the set of online lessons relating to the final years of elementary school II and secondary school. The analysis reveals that the ERE period could have been a good opportunity to work on developing students' sociolinguistic awareness, using various technological tools, such as videos, images, music, etc., considering that many schools do not have the structural conditions to do this in classroom teaching. However, despite these new possibilities, we found that the teaching of linguistic variation is still superficial, without much in-depth study of the factors that cause variation in the language; teaching is restricted to presenting the types of variation in a theoretical way, without showing students in a practical way how these variations occur. In addition, we found that the teachers had little knowledge of the use of technologies applied to teaching, which made those classes a reflection of what was already happening in public school classrooms, that is, a traditional methodology, focused on rules and the transmission of content. Clearly, the pandemic has passed and those recorded lessons will continue to be available on the internet. However, we hope that this study can contribute to improve the content made available on CMSP, and the training offered there for state school teachers, not just in São Paulo, but throughout Brazil. We also hope that the training offered will be of high quality, with the necessary topics and up-to-date materials, as well as encouraging teachers to read books, articles etc. on the subject of variation and teaching, the use of technologies and more dynamic methodologies than the traditional ones, allowing these topics to be explored in all their complexity and in full.

This study investigates the induction of polyploidy in Mandevilla in vitro, utilizing colchicine as a mitotic inhibitor. The main objective is to establish an effective protocol for polyploidization and evaluate its impacts on three genotypes of Mandevilla. Specific objectives include assessing the effects of exposure time to colchicine on the induction of polyploids, as well as the influence of genotype on the success of polyploid plant development. The results demonstrate that colchicine treatment led to significant changes in the morphological and physiological characteristics of Mandevilla, including alterations in leaf size, stomatal density, chlorophyll content, flower color and size, and photosynthetic efficiency. The findings suggest that induced polyploidization may enhance desirable ornamental characteristics. This research highlights the potential of polyploidization as a strategy to increase the ornamental value of Mandevilla and offers insights for future applications in plant breeding.

The main objectives of this study were: (1) to develop a didactic sequence that addresses specific topics in Quantum Physics (QP), focusing on debunking pseudoscientific concepts related to the subject; (2) to apply this didactic sequence in high school classes; and (3) to evaluate whether there was progress in students' understanding of quantum concepts. The justification for the study is based on the difficulties highlighted by several authors in teaching Quantum Physics at the high school level, such as the complexity of mathematical formalism, conceptual innovations, limitations in experimental approaches, the lack of didactic materials and outreach, and the insufficient time available to cover these topics adequately. Furthermore, quantum mysticism and the spread of pseudosciences, which often distort scientific principles, reinforce the need for a structured educational intervention. The didactic sequence was developed based on the studies of Antoni Zabala, aiming at a progressive and diversified structure that would facilitate students’ understanding and engagement. The methodology combined a variety of pedagogical approaches, including experimental activities and interactive discussions. The results showed that the sequence was effective: most students reported a better understanding of physical phenomena, and many felt more prepared to distinguish science from pseudoscience. Data analysis indicated an improvement in concept comprehension, highlighting the contribution of this work to the teaching of Quantum Physics in high school and to the reinforcement of critical scientific education.

With the aging of the Brazilian population, significant challenges arise for health management, while opportunities for innovation in psychogerontological services open up. The demand for specialized care for older adults requires a personalized and adapted approach. In this context, the SERVQUAL model stands out as a tool to assess user satisfaction in health services, while the Pikes Peak Training Model presents the attitudes, knowledge and skills necessary for the practice of Psychogerontology. This research was developed through the preparation of two articles, with different methodological approaches, to investigate the quality of psychogerontological services: an analysis based on a systematic review of the literature and another focused on empirical research, of a qualitative and exploratory nature, based on the perceptions of 22 Brazilian psychologists. The data collection process for the second article was guided by triangulation between the formulation of the semi-structured questionnaire composed of 11 questions, the conduct of the interviews and the observations made by the researcher. The selection of the main excerpts and observations made it possible to code and categorize the data, through the evaluation dimensions and their constituent parts. The results indicate that issues related to the training and qualification of psychology professionals represent a challenge both in the literature review and in the interviews conducted with the psychologists. These factors impact not only the quality of the psychogerontological services offered, but also influence the number of psychologists interested in specializing in the care of elderly people, their caregivers and family members. Another aspect observed, both in the literature review and in the interviews, was the association made by the psychologists between empathy, acceptance, expression of affection and interest. It is important to emphasize the importance of the psychology professional understanding the real needs of this population and, based on this understanding, applying their specialized knowledge to define the most appropriate intervention strategy for each case. In addition, it was found that psychology professionals need to pay attention to structural improvements, ranging from access to mental health services to communication channels and the resources used. As an innovation of this research, the adaptation of the SERVQUAL model to assess the quality of psychogerontological services in Brazil stands out. As an opportunity for improvement, the adaptation of the Pikes Peak Training Model to the context of psychogerontological services in the country is discussed, given its relevance. This adaptation would provide a solid basis for the training of psychologists, enabling them to deal more effectively with issues related to aging. The integration of the Pikes Peak Model into the Brazilian context, combined with the dimensions of the SERVQUAL model, can generate a significant positive impact on the quality of psychological services aimed at the elderly. It is concluded that the training and practice of psychology professionals should promote approaches that broaden and deepen the understanding of the multiple dimensions of aging, preparing them for a more qualified and sensitive performance to the demands of this population.

Diante da crescente pressão social por uma postura ambientalmente sustentável, o setor hoteleiro vem incorporando em suas estratégias de mercado a adoção de ações e práticas voltadas para a conservação ambiental. Neste sentido, o objetivo do artigo consiste em propor discussões sobre a relação entre ecoturismo e hotelaria sob a perspectiva da sustentabilidade, destacando a importância de implementar práticas e tecnologias sustentáveis nos meios de hospedagem. Este estudo foi conduzido por meio de uma revisão bibliográfica em bases de dados acadêmicas, analisando artigos, dissertações, teses e documentos técnicos sobre a implementação de SGAs em meios de hospedagem. A metodologia permitiu a identificação de desafios e oportunidades na adoção de práticas sustentáveis, bem como a análise da efetividade dessas iniciativas na redução dos impactos ambientais. Chegou-se a resultados que demonstram a necessidade de adaptação dos meios de hospedagem para o cumprimento de requisitos mínimos de sustentabilidade; e que as organizações devem investir na implementação de um Sistema de Gestão Ambiental, porque proporciona benefícios, como melhoria da imagem; conquista e ampliação de mercados; acesso à benefícios econômicos por meio de taxas mais baixas, redução de custos operacionais; manutenção das relações comerciais; cumprimento da legislação ambiental em geral; e principalmente, execução das práticas sustentáveis em prol do ambiente. O compromisso com a gestão ambiental fortalece a competitividade dos meios de hospedagem, aprimora a experiência dos hóspedes e contribui para um turismo mais responsável e sustentável, alinhado aos ODS da Agenda 2030.

Consumers are increasingly concerned about eating healthier foods. As a result, health authorities have encouraged the development of strategies aimed at creating healthier alternatives, including the elimination of trans fats and the reduction of saturated fatty acids. In this context, organogel technology has emerged as an alternative, offering benefits beyond nutritional aspects, such as being a simpler and more cost-effective process. The objective of this project was to develop organogels using different vegetable oils, based on their degree of saturation, and to evaluate the combination of two vegetable waxes (candelilla and beeswax) in different proportions. A total of twenty-one organogels were formulated with varying ratios of beeswax to candelilla wax (0:6, 1:5, 2:4, 3:3, 4:2, 5:1, and 6:0 % (w/w)) using soybean, canola, and sunflower oils. The organogels were evaluated for texture, adhesiveness, rheological properties, thermal stability, and oil-binding capacity. The results showed that the addition of candelilla wax increased the firmness and stability of the organogels, especially when combined with beeswax. The organogels exhibited high oil-binding capacity and variable stability depending on the combination of vegetable oil and wax used, with the best stability observed in gels made with sunflower oil and a mixture of beeswax and candelilla wax. Oils with a high content of unsaturated fatty acids, such as sunflower oil, showed better performance in terms of mechanical resistance, firmness, and stability. Rheological analyses showed that the Herschel-Bulkley model fit the data well, indicating that the organogels exhibited pseudoplastic behavior with yield stress. Among the formulations tested, those with a 4:2 ratio of beeswax to candelilla wax showed the highest stability and, therefore, greater potential for food applications. Thus, the results confirm that organogels are viable alternatives to conventional fats and have potential for industrial application.

Bats provide important ecosystem services, such as seed dispersal, pollination, and pest control. However, the composition and diversity of bat communities can be influenced by landscape changes. In this study, we evaluated how different landscape metrics relate to bat data collected in 18 distinct Atlantic Forest landscapes within the Cantareira–Mantiqueira Corridor in southeastern Brazil. A 2-km buffer was applied around each sampling site to calculate metrics including percentage of native vegetation cover, total edge length, patch area, and landscape heterogeneity. For bats, we computed Shannon-Wiener diversity index, Chao-1, observed richness, and abundance. Statistical analyses were performed using Generalized Linear Models (GLMs), and spatial autocorrelation was assessed using Moran’s I index. Functional groups were established based on dietary preferences and body size to facilitate the identification of potential patterns of response among ecologically similar species. In addition to analyses at the community and functional group levels, we also explored relationships between the most abundant species (N > 20) and landscape metrics. Sampling effort totaled 17.280 m²h (mist-net hours), collecting 501 individuals from 26 species, of which 80.6% were frugivorous, 10.3% insectivorous, 5.2% hematophagous, 3.2% nectarivorous, and 0.6% omnivorous. Abundance per site ranged from 2 to 65 individuals, and species richness from 2 to 11 species. GLMs did not reveal statistically significant relationships between landscape metrics and either community or functional group attributes. However, Sturnira lilium showed a significant positive relationship with native vegetation cover (p = 0.0141), with higher abundances observed in landscapes containing 10–35% native vegetation. This pattern may reflect greater food availability, as pioneer species from the Solanaceae family, preferred dietary items for S. lilium, are often more abundant in disturbed landscapes. These findings highlight the species' potential role in seed dispersal and ecological restoration in anthropogenically altered areas.
