In light of the escalating global population and the mounting environmental concerns, the quest for sustainable and renewable solutions has emerged as a paramount focus in scientific exploration across diverse fields. Plant-derived fibers stand out as a compelling sustainable option for fabricating materials due to their intriguing physical and mechanical attributes. Within this context, this study aimed to optimize the production of cellulose nanomaterials featuring varying lignin concentrations sourced from rubber tree wood fibers, and to explore their application in nanocomposite films. In the initial phase, fibers with distinct lignin compositions (15.3%, 6.7%, and 3.1%) underwent acid hydrolysis at differing reaction durations (45 minutes, 75 minutes, and 120 minutes) to yield cellulose nanomaterials with residual lignin (LCNCs). Subsequently, the study assessed the impact of integrating LCNCs, possessing both higher and lower lignin contents, along with commercially available cellulose nanocrystals (CNCs), into a casein (CA) matrix. The chemical treatments demonstrated remarkable efficacy, resulting in LCNCs with an average diameter below 4.1 nm, showcasing a high Crystallinity Index (I.C. > 70%), and achieving a reaction yield surpassing 50% across all evaluated reaction durations. Additionally, LCNCs exhibiting higher lignin content displayed notable colloidal stability (> -40.0 mV). The resultant nanocomposite films exhibited a superior I.C. compared to the pure CA matrix (34%), presenting as transparent, uniform, and easily manipulable films. The incorporation of LCNCs amplified the contact angle (θ >82.5°), enhancing the films' hydrophobic characteristics. Furthermore, films integrated with commercial CNCs and LCNCs with elevated lignin content exhibited a significant increase (p<0.05) of approximately 45% and 40%, respectively, in tensile strength (TS). Additionally, there was a 20% and 23% enhancement in the modulus of elasticity (EM) compared to the pure CA matrix. This research delineated a precise methodology for producing lignin-infused cellulose nanomaterials, promisingly valorizing rubber tree biomass residues. Moreover, it underscored the potential of integrating these materials into the casein matrix, yielding films endowed with exceptional properties, thus fostering diverse applications.

Community Development Banks (BCD) have become an important instrument for the expansion of Solidarity Finance through microcredit, largely due to the public policies that have been offered since the creation of the National Secretariat for Solidarity Economy. With the rise of ultra-liberal governments and detached from a progressive perspective after the 2016 coup, support ceased, causing the failure of these instruments characterized as Sociotechnical Adequacy (AST), originating from the production of science from social movements. of solidarity finance, which is a way of producing knowledge, therefore aims at the social appropriation of knowledge through sociotechnical inclusion, defended by the CTS field of studies. Therefore, the research analyzed the potential for financial self-sustainability of the BCD under the hypotheses of possible fundraising directly from potential investors, in order to provide and redeem the productive function of money. For this purpose, there are legal instruments such as D11646 and the PLP 93 /2007 which may enable direct fundraising by BCD. To verify this hypothesis, the study was carried out through field research with the application of questionnaires to two distinct groups: (i) BCD management team and (ii) potential joint financial investors in BCD. After data collection was carried out, they were initially treated by descriptive statistics and later by cross-analysis, through which partnerships consistently revealed the potential for capturing the target audience of the BCDs researched. However, the absence of management instruments undermines the reliability of investment returns, with Economic Science researchers playing an important role in the construction of these resources. Such conditionality results indicate, in addition to the possibility of social impact savings, the need for a repositioning regarding the management of the BCD, using internal management indicators, to maintain selfsustainability without losing the basic principle of the economy solidarity, which is a specific way of humanizing the economy. From the perspective of the CTS field, it was noted that Community Banks, as an AST, are instruments that provide a way to do science in an engaged way, with a view to social movements of solidarity finance, as well as promoting the appropriation social knowledge.

The quantum nature and dissipation-free flow of electric currents in superconducting materials have taken a central role as technological developments push forward the necessity of new methods for processing and dealing with the amount of information generated by modern consumption patterns. To enable such superconducting technologies, it is necessary to understand the underlying Physics dictating the behavior of superconductors, unveiling or allowing to control phenomena useful for applications. Due to its intrinsic relationship with the superconducting state, applied magnetic fields emerge as natural candidates for manipulating the properties of superconducting materials. These ideas motivated the research conducted in the context of this thesis, which is structured as a collection of studies in which different superconducting systems are subjected to magnetic fields, aiming to investigate and control their behavior. In the first set of results presented, the temperature of a plain Nb thin film is reduced under different magnetic field cooling conditions. Then, flux penetration patterns are studied by magneto-optical imaging (MOI). The results demonstrate how the applied field spatial distribution and direction influence the ability of a superconducting device to transport electrical currents without dissipation, without the need for any complex nanofabrication steps. Such influence is due to the emergence of different trapped flux configurations in the superconductor, either facilitating or hampering further magnetic flux penetration, effectively reducing or increasing the effective maximum current the film can carry in the superconducting state. It is true, however, that for most applications in superconducting technology, nanofabrication is required, in some cases demanding the creation of regions of suppressed superconductivity called weak-links. A different study investigates normal and superconducting state properties of Nb films patterned with a single weak-link fabricated by focused ion beam (FIB) milling. The investigation quantifies the suppression of superconducting properties and the modification of the normal flow of electrons, finding that these are linked by the degree of impurities introduced by the nanofabrication. One interesting effect is the emergence of a local peak in the magnetic field-dependent magnetization of the patterned samples. In a separate work, we employ MOI to investigate these specimens under applied fields near such local peak. This study reveals that the patterned films undergo a behavior transformation from a weak-link to a strong-link, enabling more current to flow between the unpatterned Nb regions. Quantifying the MOI data allows us to understand the flux dynamics responsible for the peak effect. In a different study, the properties of a dc superconducting quantum interference device (SQUID) presenting two parallel weak-links comprised of asymmetric constrictions of a superconducting amorphous MoGe film were investigated. It is possible to influence the behavior of such devices by modifying their geometry. The study demonstrates how understanding the relationship between the device and applied magnetic fields and currents allows preparing the SQUID in multiple energy states, readable at the same field value, thus allowing its use as a multilevel memory element. Finally, we aim to consolidate MOI as a reliable tool to quantitatively study the behavior of superconducting films under ac magnetic fields. For that, we investigate the independence of the thermomagnetic history on the ac magnetic susceptibility response of an amorphous MoSi film. This study relies on the possibility of emulating ac effects by cycling an applied dc field. The results are successfully compared with standard SQUID-based magnetometry while taking advantage of the local spatial resolution of MOI to reveal the quantitative behavior of individual flux avalanche events and the presence of zones of flux annihilation at interfaces between positive and negative flux regions.

Innovation has been the subject of study across various domains of knowledge. Within the field of Information Science, there exists a diversity of approaches to the theme. Consequently, the question arises: how has innovation been conceptualized and addressed in the research published by Postgraduate Programs in Information Science in Brazil? To address this query, the study aimed to investigate scientific publications expressed through dissertations and theses defended in the field of Information Science within the Brazilian context. The objective was to map the scientific production on the topic of innovation within dissertations and theses defended in Brazilian Postgraduate Programs in Information Science, with the aim of identifying: a) the conceptualization of innovation in the conducted research; b) the approaches employed in addressing innovation; c) the bibliography utilized in constructing the conceptual framework; and d) networks of cited works. Characterized by a descriptive and exploratory methodology, the research adopted the Systematic Literature Mapping (SLM) method to support the discussion and develop a theoretical framework for the innovation theme within the Brazilian Information Science community. Seventy-two works were identified, comprising 47 master's dissertations and 25 doctoral theses that explicitly addressed the concept of innovation. The results presented encompassed the mapping of concepts and approaches used in the innovation domain, the authors who produced the academic-scientific works, the bibliography utilized to support the epistemological conception of the concept, and the network of cited works. In the realm of scientific research, innovation concepts manifest along 03 (three) central domains: epistemological, historical, and economic-industrial. It was concluded that Innovation is a topic of research agenda within Information Science, considering information and knowledge as foundational elements in the inventive process, which precedes the emergence of innovation. Notably, innovation is characterized as an applied invention, whose utility and scope present as a viable solution to a specific need within a given context.

Hospital accreditation helps healthcare institutions gain competitive advantages, enabling them to continuously develop and adapt to successive changes in the workplace while pursuing quality in the services offered to their patients. Quality is determined by seven pillars: effectiveness, efficiency, optimization, acceptability, equity, and legitimacy, which demand professional receptivity to their activities. Professionals who possess knowledge and dedication towards their roles can accomplish the objectives of the quality policy, which strives for continuous improvement to benefit all parties within the organization. This study aimed to analyze the perception of healthcare workers regarding hospital accreditation to identify the benefits, challenges, and opportunities for improving work processes and healthcare quality. It was a descriptive-exploratory field study with a qualitative-quantitative approach. The Hospital Accreditation Process Perception Assessment (HAPPA) tool was designed with Likert scale items encompassing topics corresponding to ONA's (National Accreditation Organization) levels I and II along with open-ended questions that was formed and applied in person to 200 healthcare workers at an oncology referral hospital in the central-west region of São Paulo State. The institution has around 2,000 employees working various shifts and hours. Inclusion criteria were: being a hospital worker at all levels of education, functional literacy, and at least six months of work experience. The results showed that workers perceived accreditation as important, but expressed a need for improvement and greater professional recognition. Benefits of accreditation include improving customer satisfaction, standardizing procedures, nurturing a culture of safety, and providing opportunities for training enhancement. The challenges and difficulties indicate the necessity of collaborating among team members, having appropriate staffing for safe care delivery, and sustaining the changes made. These elements highlight the importance of complementary strategies to certification, such as continuing education - a possibility for updating professionals; aligning work processes; developing interpersonal and interprofessional relationships and collaborative practices and strengthening the organizational culture; and shared management, "giving a voice" to workers and making them aware of the importance of accreditation in the search for improvements in the quality of care, with a view to greater adherence and participation. In conclusion, the results of this study offer support for planning, since the difficulties pointed out and the need to promote the engagement of all the actors working in the institution are extremely important for improving hospital accreditation processes, through the development and involvement of the team. Additionally, the APPAH has undergone restructuring and improvement to integrate ONA III-related aspects. It can be distributed and utilized in all hospital institutions, regardless of their current certification level, to gather data and enhance staff awareness.

This thesis analyzed youth assemblages as of on research carried out in public high schools. Its conception resulted from the quadripolarity of the assemblage's conceptual scheme (strata, collective assemblages of enunciation, machinic assemblages and abstract machines) based on Deleuze-Guattarian works, and operationalized for the field with the notion of youth imbricated with the interventional research. It aimed to investigate whether young people’s capabilities on affect and be affected by at Scientific Initiation Program for High School (IC-EM) were intensified in local research, and to analyze the subthemes that presented themselves in deterritorialization or decoded. The methodology added pre-established mixed methods to the limits of its representations, thus dealing with the weekly monitoring of IC-EM, in three local schools, from September 2019 to December 2023. This period coincided with the deployment/implementation/suspension of Law 13,415, of February 16, 2017 (New Secondary Education Law), known for obstructing the critical training of young people in public secondary education. For the field results, the subtopics with intensification, deterritorialization or decoding in the trajectory of the research accompanied with youth were as follows. (1) Youth assemblages by means of the school institution: the school has shown itself to be permeated by two institutional regimes, democracy or tyranny, with episodes of oppression, but also encounters and friendship, with collective assemblage of enunciation from other places that reverberate in everyday school life and summon young people to their own modes of expression (youthful secrecy, combat against racism, respect for gender self-identification and future perspectives). (2) Young people and their families: the family bullying emerged, with criticism disguised as praise, downgrader comparisons, contradictory messages that are impossibility to comply — for young people with different inclinations and values in the family — above all the not-heterossexuals, they are shown not only as a protective institution, but as a source of repeated suffering. (3) SARS-CoV2: a viral stratum, internal to a machine assemblage where droplets or aerosols of saliva predominate, deterritorialized the routine, imposed coexistence with family members and forcerd the micromanagement of small fears. (4) Acid humor as a youth psychosocial support strategy among LGBTs+people?: emerged in one of the subgroups of students in decoding internalized meanings of mental suffering; allowing to touch difficult content in the elaboration of painful psychosocial experiences. (5) (Dis)sexuality: decoded cultural codes that confuse intensity with compulsion, harassment and violence in sexual practices; rescuing practices of freedom in machinic assemblages. (6) Indianness: young people sought ways to affirm not only indigenous descent, but a becoming-indigenous, indicative of the limit of ethnic-racial categorization, which erases assimilationist racism. School as an institution was not limited to constraining the inventive abilities of young people; before that it was a place of meetings, participation, friendship and support, where these young people could turn to those they trust. There was an intensification of the IC-EM' ability to affect and be affected in this interventional research. After all, any ability to affect and be affected depends directly on the encounters provided by the world.

Dissolved organic matter (DOM) encompasses a wide range of biologically derived molecules and is the most abundant and bioavailable form of carbon in aquatic environments. DOM plays a key role in the carbon cycle, as it influences pH and light penetration in the water column, affecting primary productivity, and serves as the primary energy source for heterotrophic microorganisms. Phytoplankton, through its metabolism or cellular death, represents a major source of DOM for aquatic systems. However, little is still known about the composition of these organic substrates and the factors that regulate their production and quality, especially from the perspective of global climate change. Small changes in phytoplankton-derived DOM (DOMp), triggered by changes in environmental factors, can cause shifts in microbiome structure and, therefore, carbon fluxes in aquatic food webs – thus, in the carbon cycle. To examine the consequences of temperature increase on DOMp, axenic cultures of Microcystis aeruginosa and Cyclotella sp. were subjected to +4°C warming experiments, with and without prior acclimation, and analyzed using flow cytometry, fluorescence spectroscopy, and quantification of dissolved organic carbon at different growth stages. Two proteinaceous fluorescent components and two humic/fulvic-like components were identified. While the composition of DOMp varies more pronouncedly with growth stages, temperature appears to induce changes in the bioavailability and carbon exudation rate of exudates. Values of some optical indices and spectral ratios differed from those reported for phytoplankton, which has important implications for understanding DOM in natural waters. Additionally, some fluorophores typically associated with humic compounds appear to include other substances of different nature and origin, potentially related to oxidative stress. It is expected that the results obtained in this investigation will advance the understanding of DOMp production processes, help refine the interpretation of DOM optical property data in natural environments, and contribute to a better understanding of the impact of climate change on key portions of the carbon cycle.

Sexuality is an integral part of the individual, and is influenced by physical and psychological factors. Fibromyalgia is a central sensitization syndrome that mainly affects women and the clinical condition involves the presence of pain, anxiety, depression, low self-esteem, and these factors can negatively influence the sexual function of this population. It is essential to deepen knowledge in this area in view of the impact of sexual dysfunction on the quality of life and well-being of women with fibromyalgia. Study 1: The aim of the study was to investigate the relationship between sexual function and central sensitization in women with Fibromyalgia. This is a cross-sectional observational study. An online questionnaire was used for data collection. The questionnaire consisted of 85 questions, including questions to assess female sexual response (Female Sexual Function Index), assessment of central sensitization (Central Sensitization Inventory) and assessment of the impact of Fibromyalgia (Fibromyalgia Impact Questionnaire). 337 participants were included, 75.7% of women had sexual dysfunction. Furthermore, the results showed an association between sexual dysfunction and central sensitization. In conclusion, the results showed that there is a high prevalence of sexual dysfunction among women with Fibromyalgia, with a positive association between sexual dysfunction and central sensitization, with desire being the most affected domain. Study 2: the objective of the study was to evaluate the influence of anxiety and depression on the sexuality of Brazilian women with Fibromyalgia, for this, a cross-sectional observational study was carried out through an online questionnaire that evaluated female sexual response (Female Sexual Function Index), anxiety and depression (Hospital Anxiety and Depression Scale). A total of 255 women with sexual dysfunction were included in the study, most of them had moderate alteration related to depression (39.6%) and severe alteration related to anxiety (43.5%). Furthermore, the results showed that anxiety and depression are associated with sexual dysfunction. It is concluded that sexual dysfunction among Brazilian women with Fibromyalgia is associated with anxiety and depression, and it is essential that a screening of sexual dysfunction be carried out among patients with depressive symptoms and who have Fibromyalgia, so that an integral approach is carried out, in order to improve their quality of life.

Graphene Quantum Dots (GQDs) are small fragments of one or a few layers of graphene with lateral dimensions inferior to 100 nm. GQDs present some characteristics similar to those of graphene, such as a high surface area/volume ratio and chemical stability. In addition, GQDs present a bandgap between their valence and electronic conduction bands. This bandgap gives rise to one of the most investigated properties of GQDs: their photoluminescence, which enables their application as luminescent sensors. In this sense, in the first work, hydrothermal syntheses of GQDs from graphene oxide (GO) were studied aiming at obtaining a material with greater photoluminescence intensity for application in luminescent sensors. The synthesis temperature, pH of the GO solution, and GO concentration were evaluated to optimize the quantum yield of GQDs. An optimized value of 8.9% was obtained. The influence of each parameter on the composition and properties of the GQDs was carried out from the physical-chemical characterization of the materials. The synthesized materials were used in the detection of Fe3+ ions in aqueous solutions by luminescence quenching, obtaining a detection limit of 0.136 M. Like GQDs, the discovery of a new class of materials known as MXenes was inspired by the discovery of graphene. MXenes are 2D materials, in which transition metal layers are interleaved with carbon and/or nitrogen layers. Such materials have demonstrated high energy storage capacity, being widely exploited in devices such as supercapacitors and batteries. However, the restacking of the MXene layers and the narrow potential window usually obtained limit the performance of these materials in such applications. In another work, nanodiamonds (NDs) were used to prevent the restacking of the MXene layers during its use as a supercapacitor electrode. The pillaring effect obtained with the NDs allowed a greater diffusion of protons between the layers of the MXene Ti3C2Tx, resulting in a capacitance of 235 F/g (561 F/cm3) when used in 3 M AlCl3 electrolyte. Furthermore, a wide potential window of 1.2 V could be used due to the reduced water activity in the electrolyte.

This thesis presents dialogues between the fields of culture and occupational therapy. Initially, we conceptualize some ideas around understandings of culture. Next, we relate the theme of culture as present in the construction of Brazilian occupational therapy, its relations with the arts, the expansion of fields and actions based on engagement, commitment and political constructions. The thesis aimed to: Identify and analyze the possibilities of occupational therapy in the interface and with the culture; to map and analyze the knowledge and practices of occupational therapists that contribute to the reflections and possibilities of the field of occupational therapy and culture. Therefore, it sought to meet research groups and other groups of occupational therapists that establish relationships with culture. How do they dialogue? What are the prospects? What relationships do they establish? Afterwards, we invited people, researchers and representatives of groups and collectives. Thus, 13 interviews were carried out, based on a script produced for this purpose and, above all, dialogues based on trajectories, practices, reflections and other constructions. All interviews were transcribed and analyzed, as well as all ethical precepts of research with respected human beings. In this way, in the results we present the profile of each interviewee, and the thematic curation of the narratives was carried out, in which five major themes of debate in the field are highlighted: Cultural, Political and Law Accessibility, Aesthetic Experience, Corporeality and intersectional relationships Finally, the narratives represented the possibilities of practices and dialogues in the cultural field whose practices revealed relationships of multiple meanings and directions. New perspectives, new horizons, new directions and other perspectives are brought as a strengthening exercise for the future of practices and debates for the field and the possibilities of interface between culture and occupational therapy. It is more about thematic curatorship than classifications, thematic or comparative analyzes that express the potential and challenges of this construction.

The COVID-19 pandemic has heightened concerns about the conditions of socially vulnerable adolescents in Brazil and around the world. Containment measures and the health, economic and social consequences increased the risks already experienced by this population. Therefore, the main objective of this research was to understand the impacts that the pandemic had with regard to social and relational ruptures caused by the COVID-19 pandemic in the lives of adolescents in situations of social exclusion, more specifically, adolescents fulfilling socio-educational measures of hospitalization. Furthermore, the aim was also to verify the influences and changes of the pandemic context on their life projects and future expectations. Based on the assumptions of the Bioecological Theory of Human Development, we sought to develop analyzes that made it possible to articulate the impact of the pandemic in the contexts of adolescents who were already experiencing situations of social exclusion and its consequences in the face of possible ruptures with significant people and spaces, as well as in your life projects. This was a qualitative, exploratory, descriptive study with a cross-sectional design. Twenty-two adolescents living in the five macro-regions of Brazil participated in the investigation, aged between 16 and 19 years old, male and undergoing a socio-educational hospitalization measure. For data collection, the following instruments were used: i) Questionnaire on the sociodemographic characterization of participants; ii) Life Project Questionnaire; and iii) Semi-structured Interview. The Thematic Analysis (TA) technique was used to analyze the data. The results indicate that the Covid-19 pandemic considerably impacted the social and relational bonds of adolescents who were hospitalized. There was an increase, specifically, of ruptures with school spaces, as difficulties already existed before the pandemic and these were aggravated by the way educational spaces were organized. But, at the same time, there was also a strengthening of these adolescents' family relationships, mainly due to the increased interaction made possible by the period of social isolation. Regarding life projects, the research revealed a positive perception among adolescents in identifying the presence of goals and expectations for the future. However, the context of the pandemic added even more difficulties to the reality of adolescents who were already experiencing situations of social exclusion, such as the absence of work and worsening socioeconomic difficulties. The thesis questions, in such a way, the uncritical and hegemonic look directed at the population investigated with regard to the topics covered. An individualizing conception of the factors involved in development can lead to biased analyzes and practices regarding important aspects for the present and future of these adolescents.

Chicken feather is a by-product widely generated by the poultry agroindustry. However, its large-scale production and the challenges associated with waste management raise substantial concerns about its environmental impacts. Chicken feathers are predominantly composed of keratin, a protein that can be potentially valued towards new biodegradable materials with desirable physical properties for various applications. Focusing on this major objective, in this doctoral thesis, keratin was extracted from industrial chicken feather waste through sulfitolysis, followed by recovery using various precipitating agents: HCl, citric acid, NaCl, and acetone. This approach enabled the extraction of keratin in a dialysis-free, fast, and scalable way, using low-cost and non-toxic reagents, with emphasis on the acetone precipitation for which a recovery yield of 80% was obtained. Life cycle assessment outlined the main environmental hotspots in the keratin production, and a circular economy concept was studied to mitigate its environmental impacts. Chemical analysis revealed that the disulfide bonds present in keratin were converted into S-sulfocysteine, facilitating the keratin processing by thermo-molding. Transparent and water-insoluble thermoplastic films were produced with desirable properties for packaging applications, for example. The precipitating agents had direct implications on the distribution of molar mass, morphology, and hydrophobicity of the keratin films. These characteristics allowed obtaining films with a range of mechanical properties, from rigid films, with an elastic modulus above 400 MPa, to films with elongation at break as larger as 70%, for a tensile strength around 10 MPa. This thesis shows the potential for valuing chicken feather waste in the development of biodegradable keratin-based materials with reduced environmental footprints.

The purpose of this research was to employ geoprocessing to analyze the physical aspects and land use to diagnose the environment in areas of permanent preservation (APPs) located in the municipality of Campina do Monte Alegre (SP). The study comprises the following stages: initially, the collection of data relating to the area under study, including planialtimetric maps (scale 1:10,000) and remote sensing products. Then the data was processed, using QGIS 3.32 software, detailing the physical aspects, the land use, in addition to demarcating and qualifying APPs in accordance with Law 12,651/2012. The final environmental diagnosis, overlapping the areas covered with native vegetation current with permanent preservation areas, it was found that the southern region of The municipality presents greater vulnerability with 39% deforested. Confirming thus, the need to recover native vegetation on site.

Corn plays a fundamental role in Brazil and globally, being an essential crop for both human and animal nutrition. Furthermore, it serves as an essential raw material for the production of a variety of products, including beverages, fuels, polymers and others. However, several factors can influence corn productivity, such as soil, climate, cultivar, cultural practices and management of pests, diseases and weeds. This scenario becomes even more challenging with the second harvest or 'safrinha' which can contribute to the permanence of hosts in favorable conditions in the field, this can provide a greater incidence of pests and/or diseases caused by insect vectors, such as Dalbulus maidis (corn leafhopper). Studies regarding the survival capacity of the corn leafhopper on alternative host plant species, that is, species that can serve as shelter and/or food during the off-season, are still scarce. In this context, it is essential to identify possible host plants and determine insect vector management to minimize losses attributed to the corn leafhopper. The objective of this work was to evaluate the survival and development of corn leafhoppers on plants. Weed species were selected because they have a similar botanical classification to corn or due to their common occurrence in corn fields. For survival tests, two tests were carried out: on groups of plants and on individual plants, where the survival, oviposition and “bridge” of insects were evaluated. Survival assessments were carried out daily after the leafhoppers were confined in cages until all insects died. Oviposition assessments were carried out seven days after infestation. To do this, the leaves were detached from the plants and cut into smaller sizes to count the eggs using a stereoscopic microscope. The existence of several species of weeds can provide refuge and food, prolonging longevity, at least for a part of the leafhopper population. It is likely that, in agricultural environments, these weeds play a role in harboring populations of migrating leafhoppers from recently harvested corn fields, thus ensuring the survival of some of these insects until the emergence of new seedlings in the area. However, it is a fact that corn plants play a very important role in the survival of Dalbulus maidis in crops, and the presence of volunteer corn plants, staggered, late and continuous plantings can play a fundamental role in the population increase observed in recent harvests. Considering the data obtained, weeds are of marginal importance in maintaining Dalbulus maidis populations.

En esta disertación, a través de un meticuloso análisis de los enunciados obtenidos de la campaña #juntospelolivro, ampliamente difundida en Instagram, llevamos a cabo un estudio de su conexión con ciertos discursos acerca del libro y la lectura. La singularidad de los enunciados de esta campaña, que tiene como objetivo promover la lectura y el libro, se enmarca en el contexto de los desafíos políticos y de salud que enfrentó Brasil entre 2018 y 2022. Para esta investigación, nos apoyamos en los principios teóricos de los estudios del discurso según Michel Foucault (1970; 1987) y Possenti (1999; 2001); además, consideramos las perspectivas de los estudios históricos y culturales sobre el libro y la lectura según Roger Chartier (1998, 1999, 2002; 2003), Abreu (2001a; 2001b; 2006), Barzotto & Britto (1998), Curcino (2010; 2016; 2018; 2019; 2020), entre otros notorios autores. Nuestro análisis se centró en la identificación de patrones temáticos recurrentes en estos enunciados de la campaña, junto con la descripción de aspectos de su expresión lingüística, en combinación con elementos visuales. Lo que distingue esta campaña de las muchas otras contemporáneas de promoción de la lectura y el libro en las redes sociales es la preeminencia de dos temas: las funciones terapéuticas (contra el aburrimiento y la ansiedad) de la lectura y el libro, y su dimensión política, ya sea como forma de resistencia a las políticas gubernamentales en curso que afectan al sector librero, ya sea como un medio para combatir la desinformación que circulaba en ese momento. Entre los resultados de nuestro análisis, cabe destacar la frecuencia y especificidad de las referencias a los beneficios terapéuticos de la lectura y el libro, como una práctica para contrarrestar las consecuencias psicológicas y emocionales del distanciamiento social y el miedo generado por la pandemia de COVID-19. Para ello, también nos apoyamos en los estudios de Biblioterapia, buscando su integración con la Historia de la lectura. En relación con el segundo grupo temático más relevante de enunciados en nuestra investigación, el relacionado con la política, observamos especialmente cuánto se atribuyó a esta práctica el poder de proteger a los lectores contra las noticias falsas, los discursos de odio y las falsedades. Tanto en las publicaciones como en los comentarios a las mismas, observamos formas de autorrepresentación como lectores, que se expresaban con un gran orgullo. Así, tanto los autores de los textos de esta campaña como aquellos que los leyeron y comentaron pudieron compartir su orgullo de ser lectores, lo cual se manifestó de manera notable en la formulación de estos enunciados.

This master's dissertation examines the role of the Relais & Châteaux association in the current Brazilian luxury tourism market. The analysis focuses on the interplay between the location and operation of hotels affiliated with this association and the Brazilian regional context. The objective is to comprehend the influence of luxury hotels in Brazil and evaluate the concept of luxury within these ventures, considering geographical factors in their locations. The study adopts a qualitative approach, grounded in a literature review to establish the theoretical foundation and guide the research, as well as an analysis of secondary sources from entities related to Luxury Tourism, both in Brazil and internationally. The data analysis follows the perspective of historical-dialectical materialism, critically interpreting the data and reflecting on the empirical reality, allowing a comprehensive and in-depth understanding of luxury hospitality in the Brazilian context. It becomes evident that Brazil holds a peripheral position in the global luxury hotel landscape, even with the current influx of international capital through the establishment of new hotel ventures. Furthermore, luxury hotels in Brazil are predominantly concentrated in coastal areas, reinforcing the national identity oriented towards Beach and Sun Tourism and in prominent financial districts, reflecting the influence of capital in shaping regions of higher centrality in spatial production. Additionally, the significant role of independent hotel associations is highlighted in positioning their members in the global landscape of luxury establishments, expanding the visibility of these ventures beyond the regional scope.
