The coordinated responding of pairs of rats that occur in close temporal proximity can be conceived as a unit of cooperation which has been shown to be modulated by reinforcement schedules, similar to individual responding. The central question of this study was whether coordinated responding can be maintained when the reinforcers that are dependent on coordination are alternately presented to one of two cooperating rats across cooperative episodes. For this, tandem schedules with two components of Fixed Interval (tandem FI FI) or Variable Interval (tandem VI VI) schedules were used, as the consequences of coordination were alternately provided across the two rats. Individual and mutual reinforcement contingencies were used as experimental controls. Coordinated responses were defined as a unit involving two responses, one of each cooperating member, occurring within an interval of 0.2 s of one another. Each coordinated response was followed by a LED light for an interval of 0.2 s in all experimental conditions. Individual response rates increased systematically throughout experimental sessions and conditions. Although the same schedules were used in all three conditions, the individual reinforcement contingency (in which one’s reinforcer did not depend on its patterning rat) resulted in a higher reinforcement rate. The alternating reinforcement condition maintained coordinated responding, but the rates and proportions of coordinated responses were lower than those observed under conditions in which reinforcement was delivered to the pair members at the same time. This study showed that simultaneity in the delivery of reinforcers to members of the cooperative episode can be a critical variable in the operant selection of coordinated responding in pair of rats.

Research data repositories emerge as digital informational environments committed to the storage, management, access, and preservation of records from scientific research, increasingly stimulated by the development of Open Science. Despite the broad discussion involving research data, one wonders how the available guidelines support the author-indexer in filling in the subject metadata during the self-archiving process in research data repositories? Given this, the general objective of the research is to analyze the recommendations for the attribution of keywords by the author-indexer in guidelines of research data repositories of countries belonging to Ibero America that adopt self-archiving to contribute to the development of theoretical and operational studies dedicated to the subject metadata. Therefore, an exploratory and descriptive study with a qualitative approach is developed that combines bibliographic and documentary research. The latter is based on identifying and selecting repositories of Iberoamerican research data that adopt self-archiving, obtained from the Re3data tool. Twenty-six research data repositories were identified, whose guidelines and respective digital environments were analyzed using six indicators to construct analytical and comparative considerations. The results point to the lack of instructions for the attribution of keywords, even when the research data repositories have formalized guidelines, in addition to the lack of mention of the subject metadata and keywords, as well as clear instructions for the representation of the contents of the research data by the author-researcher. Most research data repositories recommend the use of documentary languages and validate the terms used by the authors-researchers. In conclusion, there is a worrying scenario regarding the attribution of keywords in self-archiving in Iberoamerican research data repositories, and complementary studies are opportune to propose guidelines regarding the subject metadata in these information systems.

Abstract: Contextual factors act directly on health and functionality conditions, especially in the current pandemic scenario caused by coronavirus 2 (COVID-19), since it has affected quality of life and personal interactions. Despite this, no studies were found that have verified barriers and facilitators for the quality of mother-child interaction during the current scenario. Objectives: 1) to identify contextual factors that may contribute to the quality of mother-child interaction in infants with and without biological risk, during social distancing in the COVID-19 pandemic; 2) to compare mother-child interaction between sexes and between age groups (3-6 months and 7-12 months). Methods: Infants aged three to 12 months, 42 with biological risk and 33 without biological risk, and their mothers were included. The assessments were performed from home videos recorded asynchronously, and mother-child interaction behaviors were based on the Parent-Child Early Relational Assessment (PCERA) instrument. Forms were sent to characterize the participants; about social distancing due to COVID-19; maternal depression and anxiety (DASS-21 scale); quality and quantity of resources in the home environment (Affordances in the Home Environment for Motor Development – infant scale AHEMD-IS); Socioeconomic level, through the Brazilian Association of Research Companies (ABEP). The Stepwise multiple regression model was used to verify the association of contextual factors in the outcome variables. Shapiro-wilk test was used to verify data distribution and the Mann-Whitney test to compare the interaction between groups, sexes and age groups. The significance level adopted was 5%. Results: There was a significant difference in maternal interaction between the age groups of the risk group, mothers interact better with infants younger than six months (p=0.04) and in the interaction between the risk and non-biological risk groups, in which the group without biological risk had higher interaction scores for all dimensions, mother, child and dyad (p=0.001). In addition, there was no difference in mother-child interaction and dyad between the sexes for both groups. For the mother interaction in the group at risk, only the variable age of the infant younger than 6 months was significant (β= −8,426; p=0.0461), while in the group without biological risk it was maternal schooling (β=5,861; p =0.0352) and the greater variety of AHEMD-IS stimulation (β=0.997; p=0.0112). For the interaction of the child in the risk group, only the breastfeeding variable was significant (β=10,996; p=0.0282), while for the group without biological risk, it was breastfeeding (β=9.168; p=0.0115), age over 6 months (β=7.961; p=0.0161) and maternal education level (β=6.259; p=0.0462). For the dyad interaction in the risk group, the significant variables were age younger than 6 months (β=−53,225; p=0.0019), older age in days of infants (β=23,196; p=0.0233) , male infants (β=23,196; p=0.0110) and older maternal age (β=2,077; p=0.0225), while breastfeeding (β=13,416; p=0) .0062), maternal education level (β=10,408; p=0.0167), amount of fine motor toys (β=1,942; p=0,0392) and amount of people interacting with the infant during the pandemic (β =3,589; p=0.0004). Conclusion: Contextual factors are only relevant to mother-child interaction when analyzed together. Despite the changes that the COVID-19 pandemic can cause, most families in both groups showed no environmental damage. Furthermore, it is seen that the quality of interaction is lower in the risk group, in which mothers interact better with younger infants.

Alligned with global trends in scientific and academic book publishing, Brazilian university presses are working to make a part of their e-books catalogue available in open access. The purpose of this research is to describe the operation of Brazilian University Presses regarding e-book publishing in open access. In total, 92 academic publishers related to Brazilian higher education and public research institutions were elected as participants in this research. In order to achieve the aforementioned objective, the methodology used was descriptive in nature, with data collection based on document search and analysis of the editorial policies available on the Brazilian university press websites. In addition, a survey was conducted to capture the opinions and experiences of these institutions regarding open access publishing. The results indicate that 94.6% of the participating presses publish in open access, exclusively or associated with the commercialization of books. The business models adopted to finance the publishing activities and the open publications were analyzed: subsidy model, cross-subsidies, grants, shared infrastructure, endowments, book processing charge, liberation, hybrid print model, delayed open access and library based publishing. The most recurring experience related to open access among the presses researched is the high number of downloads. Brazilian university presses realize that it would be good to expand the open access publishing currently available, however, this practice depends on the receipts of funds directed to these books and the expansion of the editorial teams involved, which are currently quite modest in size. Based on the literature reviewed on university presses, the universe of scientific books in open access, and also from the analysis of the results, some recommendations have been elaborated aiming to contribute to the increase in open access e-book publishing by Brazilian university presses, such as: experimentation of other business models, adoption of an adequate technological infrastructure to support open access and to obtain indicators of use and impact, and specially, to systematize the open access practices in its publishing policies. Brazilian university presses are important vehicles for scientific communication and they aggregate good reputation to themselves since they indicate trends and changes in the areas of knowledge, in addition to offering valuable publishing experiences for new authors, and also, they can be pedagogical and innovation spaces for publishing.

The low processability of chitosan and the obtaining of materials with low structural stability constitute substantial limitations to the commercial use of chitosan, especially in biomedical applications. Furthermore, the need to neutralize chitosan as a biomaterial increases the inherent fragility of these materials. Thus, this thesis was developed to obtain chitosan-based materials with structural integrity in the swollen state and advantageous mechanical and physicochemical properties using a thermomechanical processing route. For this, the chemical crosslinking strategy with citric acid was adopted. The citric acid (CA), in three different concentrations, was evaluated as a destructuring agente and crosslinking agent and compared to material traditionally processed with acetic acid. The chemical structure, the destructuring capacity of chitosan powder, morphology, and physicochemical and mechanical properties indicated the occurrence of chemical crosslinking, decreased crystallinity, and increased physicochemical and mechanical properties with increasing CA content. Morphological analysis revealed never-before-seen structures related to the crosslinked material's mechanical properties. In addition, a neutralization route in a buffered medium was proposed, minimizing possible hydrolysis reactions in strongly alkaline media. The glycerol was reincorporated into the materials by immersion, and it was found that the absorbed content is proportional to the immersion time. The flexibility of the materials was recovered without damage to the mechanical strength, and the exudate retention capacity was defined for application as dressings in moderately exuding wounds. The drug release profile showed a controlled release capacity for eight days during the in vitro assay for tetracycline hydrochloride. The results suggest that a chitosan-based biomaterial can be obtained by thermomechanical processing with structural stability in the swollen state and that the neutralization and plasticization strategies effectively provide properties similar to the original materials.

Introduction: The web search engines provide access to the multitude of available information, with dynamic, accurate and visually enriched results. Due to these characteristics, contemporary users are used to the practicality and dynamism offered by open and intuitive environments such as the Web. It is necessary to rethink the descriptive treatment in the catalogs since the architecture of the current software available for libraries and the communication protocols used do not allow interoperability with search engines or with other sources of information external to the bibliographic domain. In contrast, the Web offers a set of technologies focused on discovery and communication between different domains, one of these technologies is the Schema.org vocabulary. Objective: The objective of the research is to analyze Schema.org as an alternative for representing informational resources in catalogs, identifying the main characteristics and possible benefits and challenges of vocabulary adherence in the context of libraries. Methodological procedures: This study is theoretical in nature, carried out from a qualitative approach. From the point of view of the objectives, it is characterized as descriptive and in relation to the technical procedures, as bibliographic and documentary, aiming to explore the intersection between the themes, digital catalogs and Schema.org. Results: It was identified that the vocabulary has limitations for representation in specific domains, as in the case of libraries. However, the guidelines and structure of Schema.org are flexible, allowing the development of extensions, the classes, properties, and relationships can be adapted for representation in different contexts. Schema.org vocabulary can be used with encodings recommended by the World Wide Web Consortium (W3C) for structured data. In this way, it is possible to discover information in Rich Snippets and integrate the data into the Knowledge Graph. With these technologies, search results are enriched with additional elements. It was identified that in the bibliographic universe, Schema.org was included in the Online Computer Library Center projects and aligned with Linked Data principles for structuring and discovering WorldCat records. Conclusion: It is considered that the adherence of Schema.org together with the representation instruments developed within the scope of libraries can favor the exposure of catalog data on the Web. Thus, in addition to benefiting from technologies aligned with the scope of the Semantic Web, libraries can contribute to its development by sharing structured, relevant, and reliable information.

Homogeneous catalysis is the most used process in the production of biodiesel, although this process has several disadvantages such as: the catalyst cannot be easily reused and requires parallel processes for separation and neutralization. Thus, mesoporous molecular sieves stand out as heterogeneous catalysts, due to their physicochemical properties and have been preferentially studied as catalysts. Among the mesoporous molecular sieves, the family called M41S can be highlighted, with emphasis on MCM-41. MCM-41 hybrid silicas, containing cationic surfactants in their mesopores, have very strong basic sites, capable of promoting transesterification reactions. However, these materials have low catalytic stability, which hinders their reuse. Thus, this work aimed to evaluate the stability of MCM-41 hybrid silicas synthesized with a polymerizable surfactant, 1 cetyl 3 vinylimidazolium bromide (CVIMBr). The CVIMBr surfactant was synthesized by the quaternization reaction between 1-vinylimidazole and 1 bromohexadecane. The CVIM-MCM-41 hybrid silicas were synthesized, polymerized using ultraviolet irradiation, and evaluated in catalysis of the model transesterification reaction of ethyl acetate with methanol. The characterization results confirmed the formation of the CVIMBr surfactant. XRD analysis of hybrid silicas, containing CVIM+ cations, showed that the materials presented a typical structure of MCM 41. The CVIM MCM-41 and CTA-MCM-41 hybrid silicas were evaluated in catalysis of the model transesterification reaction of ethyl acetate with methanol. CVIM-MCM-41 showed lower catalytic activity but showed greater catalytic stability up to five successive uses. As the silica containing CTA+ cations showed good catalytic activity, and the silicas containing CVIM+ cations showed an improvement in stability, silicas were synthesized with different proportions of the CTABr and CVIMBr surfactants, in order to achieve a high catalytic activity and maintain stability. Thus, the catalytic activity of these silicas decreases with the content of CVIM+ cations and catalytic stability was reached when the hybrid silica was synthesized with 30% of the CVIM+ cations and 70% of the CTA+ cations.

The demand for Specialized Educational Assistance (SEA) has been growing considerably in Brazil, as well as Integral Education, possibly because of Public Policies such as Fundeb and the National Education Plan (NEP). The NEP establishes the offer of Education full-time, with a minimum stay of seven hours a day at school, in at least half of the schools by the year 2024. However, educational policies are not always convergent, when they recommend, for example, that SEA for students with Special Educational Needs (SEN) is an extra-class offer, in contrast to school shifts, and at the same time foresee an increase in the offer of full-time schools. In these cases, it is worth questioning how schools with full-time education are equating the SEA, which cannot be offered in the counter shift? The city of São Paulo instituted in its policy three modalities of SEA: Collaborative, Itinerant and Counter-shift. Thus, based on the theoretical-methodological framework of the Policy Cycle Approach to analyze educational policies, the present study aimed to describe and analyze how SEA is equated in full-time schools of one of the regional division of education in that municipality. The investigation involved three schools, with the participation of 22 regular teachers, two specialized teachers and six principals. Data collection involved document analysis, questionnaires with open and closed questions and systematic observation. The teachers of regular education pointed out the importance of working collaboratively, in partnership with a specialized teacher. In schools where there was no specialized teacher, teachers pointed out the need for this professional to serve SEN students. Teachers highlighted the importance of school projects considering the integrality of subjects and school inclusion as a way of promoting the participation of all indiscriminately. The study suggests that full-time Integral Education tends to expand the possibilities of SEA, in addition to exclusively extracurricular AEE, in shifts, and in resource rooms, a model prioritized in Brazilian Special Education policies.

Decoloniality is a movement dedicated to continuous reflection on the Latin American cultural, political and social reality. The decolonial nature arises from the practices of opposition and intervention from the moment the first colonial subject reacted against the imperial purposes that began in the 15th century. In the academic project, decoloniality is expressed through the constitution of lines of thought, practices and authentic research in Latin America. Within the scope of decoloniality, the importance of decolonial feminism as a Latin American movement dedicated to gender and race issues in a perspective of resistance is highlighted. In view of this, the theories and methodologies of Knowledge Organization were used as emancipatory technologies as a basis for a better understanding of the conceptual arrangements on these phenomena. Thus, the general objective of this research is to establish a diagnosis and delimit a set of minimum and initial procedures for the construction of a conceptual semantic network that encompasses the narrative context of decoloniality, in order to enable its identification in the context of Information Science. Specifically, the objective is to analyze how much the so-called Fundamental Categories of Ranganathan (1967), namely: Personality, Matter, Energy, Space and Time, would allow to list a set of statements that make up the structure of decolonial narratives from notions that move of the usual denotative meanings, synthesized at the level of a conceptual map. To this end, an exploratory theoretical study was conducted based on bibliographic analysis on decoloniality and decolonial feminism. In order to structure the semantic network of terms and concepts that make up these narratives, the reasoning method of the categories Personality, Matter, Energy, Space and Time (PMEST) by Ranganathan (1967) was used, and they were expanded in the light of the suggested Literary Categories by Costa (2008). Among the results, it was found that the chosen procedures allowed a theoretical-conceptual approximation between these Categories and the elements that structure decolonial discourses, in addition to exposing how the relationship between their concepts is broad and permeated with essential connotative aspects that allow us to better understand the dimension of these themes. We conclude that studies like this are necessary so that decoloniality and decolonial feminism can achieve greater visibility and representation, becoming increasingly disciplinary content, lines of research and intervention projects, in addition to contributing to the strengthening of decolonial thinking as constitutive in Latin American Information Science.

Distance Education (DE) has been growing dramatically, being also driven by the experiences lived during the pandemic period, namely in what is conventionally called emergency remote teaching - or similar nomenclatures. In Brazilian public universities, the modality has grown predominantly through the Universidade Aberta do Brasil (UAB) System. That said, the general objective of this thesis was to analyze how public universities (state and federal), operating within the UAB System, have organized themselves in order to organically incorporate DE into their institutional practices. As for the methodology, methodological triangulation was used in the light of qualitative and quantitative approaches. In addition, the investigation had, as an epistemological matrix, the Weberian comprehensive sociology. Regarding the methodological procedures, the research was divided into two main moments, the first being carried out in Brazil and the second in Portugal. The first moment had the following steps: survey and bibliographic study; document analysis; Delphi technique; virtual questionnaire; focus groups and; semi-structured interview. The second moment, carried out in the delegation of the city of Porto of the Universidade Aberta de Portugal, included: bibliographic study and document analyses; on-site visits; semi-structured interview and; monitoring of training activities in the Azores. As a result, the thesis shows that the UAB System generated a standardization in distance courses, despite some specificities that concern the proposals of each institution. As a rule, constituting DE management centers to centralize practices in the modality. Teaching, on the other hand, relies on the division of labor and receiving scholarships to work. In learning, it is clear that the UAB System has a central-pole model, in addition to the use of the Moodle virtual environment. Thinking about the institutionalization process, some important advances were made, such as the inclusion of the modality in normative documents, constitution of a management center with autonomy in its functions, students with some opportunities and rights equivalent to those of face-to-face education, etc. But these steps were not climbed without challenges. The word “struggle” frequently appears in the speeches of the subjects participating in the study. Starting from this, we arrive at the interpretation that understands the phenomenon of institutionalization as essentially dialectical, that is, involved in institutional conflicts that move the process. In order to advance in the incorporation of DE, we argue that it is necessary to overcome what we call, in the thesis, the institutionalization of precariousness. Therefore, through the speeches and experiences of the research participants, we proposed reflections on strategies aimed at organic incorporation. It becomes important, therefore, to act in the light of the dimensions: bureaucracy, confluence between modalities, experience and organizational culture. At the end of the thesis, we present the data collected at the Open University of Portugal, defining the public DE model in that country and comparing it, as much as possible, with the Brazilian reality. We identified some approximations, but also distances. When it comes to institutionalization, the main difference concerns the eminently endogenous character, in Brazil, and exogenous, in Portugal. To end the analysis, we present hybrid education as a historical trend that will be – and is being – built at a junction between subjective and material aspects in both countries.

The forest acts directly in the interception and redistribution of rainwater, influencing the conduction of rain to the surface of the soil, helping to maintain moisture within the forest, regulating water flows and contributing to the maintenance of water quality and availability. Even though water is an essential resource for maintaining life on our planet, care for water maintenance in many regions does’t reflect its importance and essentiality. In the Amazon Rainforest region, the exuberant forest suffers from predatory exploration, which causes changes in its functionality, influencing the maintenance of environmental services and ecohydrological processes. Understanding and quantifying the influence of the forest on the water dynamics in Amazonian forest environments are fundamental for proposing alternatives that contribute to the maintenance and functionality of this biome. This thesis aimed to develop an integrated study to interpret the water dynamics and understand the effects of the exploratory activity of a Sustainable Forest Management Plan on the hydrological processes in Amazonian forest environments in an area of public native forest under forest concession in the Jamari National Forest (Flona do Jamari), state of Rondonia, Brazil. The study was carried out in the Jamari National Forest (Flona do Jamari), Rondônia, Western Brazilian Amazon where the predominant vegetation is of the Open Ombrophilous Forest type, and the climate is of the Aw-Tropical Wet type, hot and humid with two distinct periods: wet (October to April) and dry (May to September). Two areas were selected: one with preserved forest (AN) and the other logged (AE). In the selected areas, 3 plots (P1, P2 and P3) measuring 20 m x 20 m were installed and monitored monthly between October/2019 and October/2020 to obtain the necessary information to characterize the structure of the vegetation, the distribution of rainwater, the accumulated burlap stock, and interpret the behavior of the main soil physical attributes. The results of this study point out that the dynamics of rainwater distribution behavior over the monitoring period was similar among the areas, reflecting the high temporal and spatial variability, as well as the seasonality of the region. The internal precipitation (Pi) was the variable that most influenced the effective precipitation (Pe) presenting higher average than the open precipitation (Pa) in most months of monitoring for the natural area (AN). The hydrological variable Et was the only one that showed statistically significant difference between the areas, which may be related to the difference in the density of individuals observed. The dynamics of accumulation of burlap and its fractions was similar between the areas, and the accumulation was strongly related to the seasonality of the region. The water retention capacity (CRH) of the burlap fractions contributed effectively to the CRH of the total burlap stock, which showed higher rates than the effective water retention capacity of the burlap (ERH). The hydrological behavior of the soils of the evaluated areas was influenced by the characteristics of the vegetation structure, hydrological variables, and variations in soil physical properties over the monitoring period. The research helped to understand the hydrological process of the understory in the forest areas, and according to the data from this study, it’s possible to conclude that the forest exploration activities made by the Sustainable Forest Management Plan affected the hydrological behavior in the explored area.

The development of new concrete technologies has accelerated in recent years, combining performance and demand for sustainability. Therefore, the development of a steel fiber reinforced concrete and produced with replacement of the natural coarse aggregate by recycled aggregate is perfectly suited to this context. Due to the more porous nature and crushing process that originates the recycled aggregate, the use of steel fibers in the mixture mitigates the negative effects due to the presence of recycled aggregate in concrete, creating the steel fiber reinforced recycled concrete. Considering that discussions about this type of concrete are a relatively new field, the fundamental objective of this study was to describe the current knowledge on the subject, providing an overview of its mechanical behavior, contemplating the effects of recycled aggregate and fibers on workability and concrete strength. A systematic review on recycled concrete reinforced with steel fibers was carried out; studies about the use of recycled aggregate, steel fibers and evaluated the resistant behavior of concrete were selected. Once the references that fit the scope of this study were selected, the main findings on the influence of recycled aggregate combined with steel fiber on the compressive and tensile strength of concrete, modulus of elasticity and workability of recycled concrete reinforced with steel fibers were presented and discussed. The presence of recycled aggregate causes a reduction in the compressive strength and elasticity modulus of concrete; for substitutions above 50% the effects are more pronounced. Also, the incorporation of steel fibers promotes a reduction in the workability of the mixture, a significant increase in the tensile strength and, indirectly, an increase in the compressive strength of the concrete. Mineral additions and self-compacting concretes were also beneficial for increasing compressive strength and improving concrete workability, respectively. The systematic review also revealed that analytical models for predicting the mechanical properties of this concrete are based on the strength of the reference concrete, volume of recycled aggregate and volume of steel fibers incorporated into the mixture. The models found allowed estimating the compressive and tensile strength as well as the elastic modulus of steel fiber reinforced recycled concrete. The predicted values were compared to values available in the literature. The predicted compressive strength was in agreement correlation with the experimental values, while the tensile strength was overestimated by analytical model.

A recurring problem in the construction market is the impact caused by civil construction waste (RCC) since they present themselves in different ways, which can be environmental, social, sanitary, visual, and economic. Among many factors that corroborate this situation, the most critical is the need for planning and more efficient management, with correct and more accessible information. In this way, this work proposes to develop a new tool that helps the management of civil construction waste, through the development of a new technology that promotes the proper and more efficient destination of these materials. Therefore, the Management Plans required by the National Solid Waste Policy (PNRS) and the definitions established in CONAMA Resolution n°307/2002 were used as a basis for instrumentation, proposing interventions that promote reduction, reuse and recycling of these solid wastes. These measures were defined from the literature review, document analysis and quantitative and qualitative research of current projects. With this, the main deficiencies in construction waste management projects were identified, which showed the need to have greater access and greater control of management information, as well as the possibilities of using this waste that avoiding its disposal. Therefore, the objective of this work was to develop an application that works as a mobile tool capable of diagnosing the generation of civil construction waste at construction sites and analyzing the recycling potential, in addition to the adequate destination of this material, promoting the instruction of the professional responsible for the disposal of RCC for the most correct way to dispose of them. Thus, the Application ReciclaObra proved to be efficient for its purpose of assisting in the management of construction waste in construction sites. Moreover, the tool showed to be able to expand the accessibility of professionals to the inserted content, being this information about civil construction waste, how to perform proper segregation, the best form of storage and sorting, the possible disposals, how to perform the disposal correctly, in addition to following and elaborating the Waste Management Plan, all of this in an easy and practical way.

Previous studies have reported associations between low levels of social skills and the prevalence of depressive symptoms in adolescents. Although substantial quantitative research has been carried out on this association, there have been few qualitative investigations into this topic. This study explores the association of depression symptoms and social skills repertoires in adolescence qualitatively, using photo-elicitation. Eight Brazilian adolescents were divided into two groups considering the presence or absence of depression symptoms, gender and socio-economic conditions. Participants were asked to take six pictures regarding a specific question. Individual interviews about their images were conducted. Visual and textual data were analysed using Thematic Analysis and four guidance questions. Socially skilled behaviours were associated with adolescents' perceived support and considered a protective factor for depression during stressful life events. Relationships with parents and new school colleagues were the primary sources of social skills challenges. Parents’ lack of social skills seemed to be associated with adolescents’ low social skills repertories. Hobbies were found to facilitate adolescents’ engagement in social interactions. The study extends our knowledge of how adolescents experience the association of depression and social skills in their daily lives, contributing to inform adolescents' and parents' social skills training focused on decreasing adolescents’ depression symptoms. Limitations and implications for practice and suggestions for future research are discussed.

Cette recherche porte sur une investigation des concepts de volonté de savoir et de volonté de vérité chez Foucault, dans ses études du début des années 70. La volonté de savoir prend différentes formes, si l'on observe différents moments historiques. En philosophie, Foucault l'identifie à partir de modèles; il développe ainsi un modèle aristotélicien, et, d'autre part, nous présente le modèle nietzschéen de la volonté de savoir. Dans le premier, nous avons une implication entre le désir de savoir, la connaissance et la vérité qui reposent sur un sujet de connaissance ; dans le second, on a une dé-simplification de ces instances, une « tentative de libérer le désir de savoir de la forme et de la loi de la connaissance » (FOUCAULT, 2014, p. 23). De tels modèles constituent une première approximation de cette volonté. Pour faire une « morphologie de la volonté de savoir », Foucault (2014, p. 178), parcourt d'autres champs du savoir à la recherche d'exemples dans les pratiques judiciaires, dans celles-ci, il repère une volonté de savoir « anonyme, polymorphe » qui s'éleve à une volonté de vérité; volonté qui cherche la vérité. On voit apparaître ce type de volonté lorsqu'il analyse les rapports entre savoir et pouvoir dans la société grecque. Nous comprenons que Foucault exploite un cadre conceptuel qui implique les thèmes: de la vérité, de la connaissance, du savoir, du pouvoir et du discours, dans cette période. Dans le développement de cette thèse, nous avons exploré ce cadre. L'élément de vérité acquiert une importance particulière le long de cette voie, car il permet la formation de systèmes d'exclusion; Dans l'analyse de la vérité, le recours à Nietzsche permet à Foucault d'effectuer un double déplacement : démembrer la vérité du savoir, et la volonté de vérité, pour construire une histoire de la volonté de savoir et de la vérité à partir d'un autre fondement, qui n'a plus le sujet par référence ou volonté par faculté.

As consequence of the recent occurrence of the disease known as Olive Quick Decline Syndrome (OQDS), caused by Xylella fastidiosa subsp. pauca (Xf-p), in olive trees (Olea europaea) there is a lack of scientific information about the biology of this pathogen in olive trees that can help to understand this pathogen and support discussions about management strategies. From these numerous gaps in the practical knowledge of this pathogen, this work has as objectives: 1. to evaluate the occurrence of vertical transmission of the bacterium; 2. to determine the distribution of Xf-p in plants with different degrees of severity; and 3. to establish a low-cost diagnostic method with the possibility of execution "in farm". Olive branches taken from an asymptomatic plant, but infected with Xf-p, were propagated in a greenhouse and the resulting seedlings were analyzed for the presence of the pathogen by real-time quantitative PCR (q-PCR). The estimated vertical transmission rate at 32 months was 57.74% (41 of 71 nursery plants) and only one plant of the 28 Xf-p-infected (0.014%) showed symptoms of OQDS. To achieve the second objective, samples from 3 plants of the cultivar 'Grapollo' showing low OQDS severity (only one branch with symptoms) and one with symptoms generalized throughout the canopy (high severity) were collected at different positions in the canopy and root system and analyzed for the presence of Xf-p by qPCR. Even under conditions of low ORDS severity positive diagnoses for Xf-p were obtained between 30% and 57% of the samples collected on asymptomatic branches, while on symptomatic branches 77% of the samples were positive. On the other hand, in plants with high incidence of OQDS 82 to 100% of samples were positive. Finally, the diagnostic method based on printing of branch extracts on nitrocellulose membranes and identification of Xf-p by serology (Tissue-Print: TP - objective 3) showed promise, but with needs for improvement since the agreement of the results between TP and qPCR techniques was only slightly partial (K = 0.01 to 0.20) according to the Cohen-Kappa index.

This research refers to the analysis of the way in which a legislative framework can guarantee or distort the application of the constitutional principle of equality between individuals during the legislative decision-making process. The 1988 constitutional text contemplates the rights and guarantees that promote the well-being of all, without distinction of origin, race, sex, color, age. In turn, the political participation of minority groups still does not represent the structural reality of Brazilian society, thus, in this research, a verification of this scenario in an approach to the formulation of Brazilian land policy, resulting from the legal process and, historically permeated by the predilections of a rural elite, which in 2008 was consolidated in the Agricultural Parliamentary Front (FPA), to the detriment of the interests of others involved. Thus, the objective of this research was to verify how the legislative institutional framework can guarantee or distort the application of the constitutional principle of equality between individuals in the course of their decision-making process, taking into account the performance of interest groups. In this sense, the methodology was based on the investigation of the following categories of analysis: i) the structure of the land policy legislative process, based on the proceedings in the National Congress; ii) legislative proposals that dealt with rural land policy between 2008 and 2018, under the interests of the Agricultural Parliamentary Front (FPA); iii) the role of FPA members in the land policy decision-making process. From these analyses, it was possible to understand to what extent the FPA manages to foster conditions that enable the success of its demands through the legislative institutional arrangement, acting in the defense of sectoral interests and in strategic positions in the decision-making process of land policy aiming to promote the defense of rural interests to the detriment of the other beneficiaries of such a policy.

This work aims investigate how emphasis and positioning regarding the topic of gender modify by comparing two different gender presidents: Luiz Inácio Lula da Silva and Dilma Rousseff. Both are part of the same party – the Workers' Party – which would indicate a continuity of emphasis on agendas and priorities between governments that followed each other and had as a legacy significant advances around policies for minorities. The question that guided the research was: would women place more emphasis on women's (gender) issues when they occupy spaces of power? Thus, analyzing the existence of a rupture in thinking and political positioning between the two presidents was essential in investigating whether the difference in gender roles becomes an element that influences the elaboration of a compatible presidential communicative agenda. To carry out this work, a content analysis (BARDIN, 2009) (KRIPPENDORFF, 1997) of the presidents' messages between the years 2003 and 2016 was carried out, based on lexicometry, using the IRAMUTEQ software. The results showed a greater presence of terms related to gender and policies for women in President Dilma's speeches, pointing to the importance of presence in decision-making and power spaces for modulating the thematic emphases of governments in their communications.

By studying fossil bite traces, we can reconstruct the behaviour of extinct organisms and better understand past communities, ecology, and ecosystems. Herein we analyse bite traces on a fragmented sauropod rib from the Upper Cretaceous of the Bauru Basin, southeastern Brazil. The fossil was collected in the Ibirá municipality region, São Paulo State, in the strata of the São José do Rio Preto Formation (Santonian-? Maastrichtian). The analysed specimen displays nine tooth drag traces on its external surface, produced between six and seven biting events. The traces consist of shallow linear grooves, with tapered ends and a serrated or smooth edge morphology. They can be classified as Linichnus serratus, Linichnus bromleyi, and Knethichnus parallelum and were produced by an organism with ziphodont dentition, most probably an Abelisauridae. These are the first feeding traces evidences the interaction between theropods and Titanosauriformes in this geological context. This work adds to the knowledge of the Bauru Basin palaeoecology and palaeobiology and expands the record of Mordichnia of Gondwana
