This study aimed to analyze the role of insider trading and institutional investors in the informational efficiency of the Brazilian stock market. The study was carried out in two parts, each dealing with the role of one of the agents. The first part analyzes the insider trading determinants and effects on the Brazilian stock market, using the trading information available in Comissão de Valores Imobiliários 358/2002 reports. The sample was limited to 56 companies in the IBrX-100 with available data from December 2016 to June 2018. The results indicate that the insiders negotiate when there is high liquidity, that their negotiations do not affect the stock prices informativeness and do not imply in long-term abnormal returns. The results expose the demand for greater transparency of information about insider trading since only the trading did not indicate evidence in prices movements. The second part analyzes the feasibility of stock trading or the threat of liquidation as a governance mechanism. Proprietary data from the Formulários de Referência (FR) of publicly traded companies in Brazil was used, with a sample of 254 shares from December 2009 to December 2017. The results indicate that the number of institutional investors is not related to stock returns, but that they increase the incorporation of information to the stock prices and that this relation is greater in the "preferential" class of stocks. However, it was not observed that these mechanisms increase the performance of Brazilian firms.

The emergence of Information and Communication Technology (TIC) has given rise to a new paradigm in post-industrial society: that of technological evolution over information. This has led to the dynamization of the media used by computers and the Internet, especially in the diffusion of what is known as cyberspace. These changes also had an impact in the scientific fields that have as praxis the relation between the analysis and object: the information, adapting to the transformations caused by the technological progress, producing instruments to rationalize and control the increase of its registers. Thus, the transition from analog to digital documents proves unquestionably that TICs have enabled different forms of interaction between individuals, has altered the way of thinking information management in the virtual environment, mainly through the intermediation of hardware and software. In this way, free software plays an essential role in the storage and preservation of information, emphasizing Archivematica. In order to penetrate the aspects of functionalities and characteristics of said system that have eight guides responsible for the information packet process (SIP, AIP, DIP), it was taken as a point of analysis to Resolution nº 43 of CONARQ, which establishes guidelines for implementation of the so-called Trusted Archival Digital Repository (RDC-Arq). Thus, this research had the objective of evaluating Archivematica from the elements of Resolution nº 43. As a method, it presented a descriptive, documentary and qualitative character in comparative bias, confronting the tasks of the software in evaluation to the reliability requirements posted of the mentioned regulation. The results demonstrate the full compliance with the requirements of Resolution 43, which supports Archivematica as a Trusted Archival Digital Repository. It is concluded, then, that all the elements inserted in the mentioned directive were encompassed to such software, characterizing it as an RDC-Arq.

Information Science studies the informational paradigms and it is concerned with the subject of information, that is, the one who creates, shares and uses information. As a scientific field that assists the mediation of information for society, this science also targets to intermediate the inclusive information and to attend to the diversity and the profiles of users, especially when talking about information as object of meaning and interpretation for the Informational subject. The collection, dissemination and use of information have become a essential processes in the professional, social and personal life of individuals for both informational / social inclusion and for the accomplishment of activities. In this context, the general objective of this research is to analyze the information management processes in the Accessibility Laboratory of the Zila Mamede Central Library of the Federal University of Rio Grande do Norte, from the perspective of the Choo model (2011), aiming at the informational accessibility of students with visual impairment. This field research has a qualitative approach, whose data were collected through a semi-structured interview applied to 14 subjects, among managers, employees, scholars and laboratory users, and analyzed based on the content analysis method. The results revealed that the respondents presented common informational needs for the accomplishment of the activities, however, also, there are specific demands. The higher the hierarchical position, the more information sources are used to carry out the activities in the laboratory. In the organization, storage, retrieval and distribution of information by the respondents the digital form prevails. There is a certain lack of knowledge regarding the products and services offered by the unit, since some of the subjects only know those who use them more frequently, and also a communication problem which affects the delivery of material to the users of the laboratory, that doesn´t share the information received, only stores it for its own use.

We investigate the management of the scientific and technological information assets, in particular the patents, of the Postgraduate Programs of the Federal University of Paraíba in partnership with the UFPB Agency of Technological Innovation (INOVA-UFPB). Under the cognitive perspective of the fundamental equation of Information Science, it searches to demonstrate how the value-information, which holds intellectual property, is related to the principle of innovation (it evokes the strategic congregation of necessary actors represented by a Four-Leaf Clover: university, company, government and investors, in order to provide an adequate environment for the proliferation of Homo Inovatus) and, in some moments, in addition to the principle of transparency, are capable of generating profitability, absolutely essential to social, cultural, political and economic life. It has as a research question, from the information science, the investigation of the intellectual property of the postgraduate programs of the Federal University of Paraíba (UFPB), questioning how the UFPB postgraduate programs treat and manage the information assets that originate from them through dissertations, theses and other assets that are produced. It is constituted as objective to analyze the practices and perceptions adopted by the Coordinators of the UFPB Postgraduate Programs with regard to the management and protection of information assets. The methodology uses a qualitative approach, based on the documentary research analysis, UFPB database, as well as semi-structured interviews with postgraduate programs coordinators, researchers / inventors of technological information assets and INOVA-UFPB leaders. We verified that it has been applied the management of the scientific and technological information assets produced in the PPG - UFPB, even though they have not been complied with the dictates of Resolution 18 / 2017. It is expected, on the other hand, a more effective integration among the actors involved in the invention, management and protection of information asset as a four-leaf clover: UFPB, government, companies and investors (individuals or corporations), favoring an open innovation environment.

Human rights violations of lesbian, gay, bisexual, transvestite, transsexual, queer and intersex (LGBTQI +) express themselves daily in different forms and types of prejudices, discrimination and violence, ranging from psychological, physical, sexual violence, threats, until death. The challenge is not coping with the violence and homicide of LGBTQI +. Another hypothesis is located in the construction of a socio-historical of heteronormative character, which censures as transgressions of the heterosexual norm. What has led us to question ourselves as a society marked by heterogeneity between informational people and the process of empowerment of transgender individuals? What is the use as you are in analysis as being informational of the users center LGBT Rights Reference Center and the Confrontation in Homophobia in Paraíba and as its influences in the process of empowerment. It uses the theoretical contributions: gender relations, informational practices, empowerment and habitus. A research is characterized as descriptive and correlational. It has documental and field characteristics. It has quantitative and qualitative nature. It made the use of records of attendance of people 544 users as attended in LGBT in the period between 2015 and 2017. Descriptive statistics was used as an instrument of analysis of numerical data. In the second moment, to understand how the information is informative and search the meanings that the transsexual subjects have to their experiences and their expressions of expression applying the semi - released interviews. The sample comprised a transvestite, a transsexual woman and four trans men. Thus, we use a qualitative approach and through content analysis as the subcategories and their subcategories: meanings of the transsexual experience (subcategories: Perception of self, appointment, family, school, work); informational techniques of transsexuals in the interaction with the Espaço LGBT (subcategories: sources of information, knowledge of the Espaço LGBT, services used); The information and empowerment (subcategories: resignification, emancipatory actions, information in the process of empowerment, importance of the informative information of the Espaço LGBT). An analysis of the results obtained in this study could have been carried out through an access information system and / or disseminated by the Espaço LGBT with the process of empowerment of transsexual individuals. This method, the process public in the practice information has not supported, there are, the, which is not, which is not, the identities of genitive distanced the legitimized by the heterosexual norm are conceived as abject and marginalized. Thus, access to the database enabled entrepreneurial companies to carry out individual and collective emancipatory actions that consolidate the continuity of the empowerment process. Finally, it is reiterated that Information Science is configured as a field of fundamental knowledge in the subversion of inequalities and a generation of knowledge about the hegemonic ones oriented towards the sexual and gender differences.

The study considers the archives as institutions and spaces of consignment and hermeneutics that allow control and access to information, but which, moreover, are located in areas of political interrelationship. In approaching governmentality, it seeks to situate it as a heuristic instrument of practices and techniques of government execution within political rationalities. Concepts are articulated in order to perceive the strategic, technical relations that promote the constitutive rationalities of the archive as an instrument of political power. Thus, the research describes the dynamics of the archival institution from the concept of "governmentality", as developed in the work of Michel Foucault. In order to do so, it undertakes reflections on the contexts that would lead to the over determination of the information phenomenon and the frames of social memory from the constitutive rationalities of the archives. It adopts as a methodological principle the notion of "genealogy" present in Foucault and Nietzsche, which led to the characterization of a bibliographic delineation research, in the restricted use of secondary sources to articulate theoretical, conceptual and analytical elements of the conceptions of "governmentality", rationality and which, in turn, were substantial for the procedural undertaking of research at the descriptive level. It also considers that the archive is a device of political power, through which actions of governmentality are operated in the instances of information control and knowledge, as well as surveillance, capture, registration and use of information in panoptic practices. It is, therefore, a research that presents the archive as a strategic political-administrative tool of the State, through the disciplinary and vigilant use of the behavior of the subjects and the population.

The studies that are based on the principles of Knowledge Management (KM) have their bases linked to the creation of environments favorable to the controlled sharing of the knowledge of each individual. This dissertation had the objective to analyze the practice of Management by Competences (MbC) applied to Graduation Degree in Archivology at the national level. The four specific objectives are to recognize the compulsory subjects that form the common axis between universities; to point out the competences required for the course through common compulsory subjects; to map the technical-professional competences of the teachers who teach the common compulsory subjects to the courses; and to compare the essential competences of the courses with the essential individual skills of the teachers. As far as the methodology is considered of direct documentary nature because uses primary sources, the method is inductive, whereas the objectives are exploratory and descriptive, applying the qualitative and quantitative-decritive approach. As for the procedures were used the statistical and typological, since the dependent and independent variables are the categories and Lattes résumé of the teachers respectively. The research universe used is the common compulsory subjects of the 16 universities that have Graduation Degrees in Archivology authorized by the Brazilian Ministry of Education and the teachers who work in their respective disciplines. Lattes résumé were analyzed according to the Content Analysis method, with the Management by Competences guidelines and descriptive statistics techniques. The results indicate that there are indications of the application of Management by Competences in the common compulsory subjects of Graduation Degrees in Archivology in Brazil. The analyzes and discussions developed allow us to conclude that the hypothesis raised, that the teachers of Graduation Degrees in Archivology are allocated in the disciplines according to their technical-professional competences, is partially true and corresponds to half of the categories of common compulsory subjects. While the other half do not have equally positive rates. If MbC is employed in an adequate, efficient and effective way, it can heal or minimize the problems pointed out and increase the indexes found during this research, besides adding numerous benefits to the public service. It is hoped that with this work, the MbC can be considered as an emergent solution to the questions that are presented in said courses.

Nowadays, information is one of the most important tools for coping with historically oppressed social segments, such as black women. Based on this premise, this work aimed to understand if/how the Informational Practices developed by black feminists, they're part of Bamidelê - Organization of Black Women in Paraíba, have contributed to the construction of Critical Information Literacy, which enable them to orient their actions to confront relations of domination/submission of gender and ethnic/racial. For that, it was carried out throughout the work: 1. The survey of the socioeconomic profile of the black feminists who work in Bamidelê; 2. The mapping of Information Practices performed by them; 3. The identification of the Informational Practices that have contributed to the construction of a Critical Information Literacy by these women; 4. The analysis of how the Critical Information Literacy contributes to the confrontation of the relations of domination/submission of gender and ethnic/racial, by the black feminists of Bamidelê. It is a study conducted through field research, with a qualitative approach, where data were collected through semi-structured interviews. It is a correlational research, which aims to relate the concepts of Informational Practices and Critical Information Literacy. The data were analyzed through the thematic content analysis, through the categorization technique, based on the analytical categories discussed in the paper. The research showed that the Information Practices developed by black women happen in two scopes: that of the subject, which refers to the experiences of oppression experienced by these women and their action in the search of strengthening; and that of the institution, which has to do with practices aimed at empowering other women. The Critical Information Literacy, on the other hand, is developed throughout the life, from the Information Practices of these women, and relates with the reflection on its informational needs, the construction of the information in alternative spaces and the development of a critical sense information, these points together contribute, through the mutual strengthening and use of constructed information, to the confrontation of the relations of oppression/submission experienced by them.

The objective of this study is to investigate the relation of contingency factors in the adoption of management accounting practices in the agroindustrial sector of the state of Paraíba-PB. As a methodology was used a survey through a structured questionnaire, with open and closed questions made by the researcher in an interview with the representatives of the enterprise investigated, obtaining as a sample thirty-two agroindustries. The questionnaire was composed of 84 questions, divided into 4 blocks, in which the respondent was asked to select among the assertions that best meets their perception about the topic. Data analysis was done through descriptive statistics from frequency observation, inferential correlation analysis and Cluster analysis using statistical software and the Cramer V test, with a significance level of 5%. As results, it was possible to perceive that the management of the companies surveyed is more related to the use of traditional practices. The practices of cash flow, break-even, analysis of product profitability and profitability of the segment, classified as information for decision making, stand out among the practices with the highest perception of adoption. The Balanced Scorecard and the Economic Value Added (EVA) were among all the managerial accounting practices, the ones which presented the lowest rate of adoption. It was noticed the increase in the adoption of management accounting practices in agroindustries that are inserted in stable environments, possessing high technology of medium and large size, with functional structure and strategy focused on differentiation. The adoption of traditional practices prevails in the different clusters, however, the levels of adoption of modern practices in groups of agroindustries inserted in more stable, high technology or larger environments are raised.

The objective of this study was to analyze the relationship between the use of managerial procedures and the process of strategy development in the smaller companies that are part of the Cariri Western Paraíba region. With support on the principles of Resource Based on Vision Theory (VBR), we adopted a perspective of the internal environment, where are produced and made available the informations to the managers. This is a descriptive survey, developed by means of a survey of information about the data that were released in five parts, the first and second part treated of the description by respondents and companies, a third and a fourth , the use and importance of management artifacts, and the fifth approached strategic procedures. It was applied to a sample of 55 companies from the supermarket sector in the region of Cariri Western Paraíba, chosen by accessibility. The analyzes were carried out using descriptive statistics as a Spearman correlation, in order to verify the difference between: profile of the participants, profile of the companies, application of managerial procedures and process of elaboration of strategies. As a result, the manageable accounting procedures more used are operational control (52.1%), followed by costs (33.4%) and the less used are accounting statements (38.9%) and other artifacts (46 9%). The importance of these procedures we found that - Control rules ensure that data are controlled, costs, accounting controls, and other artifacts – are considered important or very important to the respondents, indicating a divergence between a use and a perception of importance. The elaboration of process aspects of strategy got 65,4% of agreement with the 32 analyzed variables, beeing that the creativity and intuition were considered by the sample how basilars elements on the strategey formation, obtaining a higher average on the presented evaluation (47,3%). In what concerns to the correlations, the participants and companies profile showed up practically indifferent to the use of acountting management tools and to the process of strategic elaboration, in this presenting some correlations with the schooling and time of action of the participants. Finally, in relations between the use of accounting procedures and the process of strategic elaboration was mainly that the control of cash, balance sheet and the break-even point,were presented greater recurrence and on the other artifacts there was a more egalitarian distribution between analyzed procedures. Thus, the results have evidenced the reaserched understood the importance of managerial processes in the strategic process, but they still do not use them fully, which may compromise a search for a competitive differential.

The aim of this research is the analyze the Social and Emotional Competencies (SEC) of managers of Social Security Agencies (SSA). The theoretical framework was divided in three parts: a managerial action in the public sector, as managerial competences in the public service and the social and emotional competences. This last part is divided in the subsections: measurement of the CSE construct and the need for a scale to measure the CSE construct of managers. The methodology of this work has a qualitative, exploratory and descriptive approach, and it is divided in two stages: the group interview by a focus group and the application of a survey. The research was developed together with APS managers. In the first stage 16 managers participated and in the second stage 424 servers in management positions answered the questionnaire. The data obtained in the first stage were analyzed comprehensively and interpretatively, while the data of the stage were quantitative using SPSS and R software, which allowed the accomplishment of correlation analysis, reliability and confirmatory and exploratory factorial . The performance difference between the working and managerial groups may be more experienced and less experienced through the non-parametric Mann-Whitney test. The main result of this work was the validation of a scale to measure as CSE of APS managers. Some differences between groups for the socioemotional competences defined in the scale (emotional awareness, emotional regulation, teamwork, self-control and emotional creativity) are verified. The final scale has 25 items and can be validated in other professional contexts.

Native to Brazil, Schinus terebinthifolius Raddi is a species known for the reddish-pink color of its fruits, which have great industrial economy importance, are sold as a condiment and also used for the recovery of degraded areas. This species can be sexually propagated, where studies regarding the seed quality to know its agronomic behavior are necessary. The present work was developed in the Laboratórios de Análise de Sementes and Fitopatologia of the Centro de Ciencias Agrárias of the Universidade Federal da Paraíba (CCA / UFPB), in Areia - PB, and aimed to evaluate the physical, physiological and sanitary quality of seeds of S. terebinthifolius, from 15 different mother plants located in Pocinhos - PB. Water content, color, one thousand seed weight, germination, vigor (first count, germination speed index (IVG), emergence, emergence speed index (IVE), length, root and shoot dry weight, in addition to a sanity test were evaluated. A completely randomized experimental design was used. The seeds of the mother plants used had low physiological potential and ranged from 2 to 36% among the plants in the same area considered as unsuitable for replanting due to the low vigor of the ir seeds. Potentially pathogenic fungi, characterized as field pathogens (Alternaria sp., Botrytis sp., Chaetomium sp., Cladosporium sp., Colletotrichum sp., Curvularia sp., Nigrospora sp., Pestalotia sp., Phitomices sp. and Phoma sp.) and storage (Aspergillus sp., A.niger, A. flavus, Fusarium sp., Penicillium sp. and Rhizopus sp.) were detected in the seed samples.

The forage palm of the genus Nopalea and Opuntiae is an important crop in the feeding of ruminant animals, it presents resistance to the lack of water, at high temperatures, to poor soils, but it is evident the reduction in crop productivity, due to the increase of damages caused by pests, as is the case of the scale cochineal Diaspis echinocacti. Thus, an efficient way of minimizing these damages is the adoption of integrated pest management (IPM), in which the use of resistant varieties is included. In this sense, the objective of this research was to evaluate the biological aspects of D. echinocacti and to identify species in vitro and ex vitro resistant to this pest. The research was carried out in the Laboratory of Entomology and in the Laboratory of Cell Biology, both of the UFPB / CCA, the execution of this research was divided into three articles. In Article I the biological aspects of D. echinocacti were evaluated in different species of Forage Palm and found that the species Opuntia tune presents higher averages in the viability of eggs, in the fixation of nymphs of 2nd / 3rd instars and in the adult phase of the species D. echinocacti. In addition, the species Nopalea sp. provides smaller numbers of eggs, 3-inner nymphs and adult insects. Regarding the duration of the period of each stage evaluated, the embryonic period of D. echinocacti lasted 4 days, the nymphs of 1st instar 9 days, nymphs of 2nd instar 7 days and nymphs of 3rd instar for 10 days until adult emergence. II. The objective of this experiment was to select species of forage palm resistant to D. echinocacti. In this experiment it was possible to conclude that the species Nopalea sp. showed to be highly resistant to D. echinocacti and O. palm is indicative of scale cochineal, in addition, O. stricta palm scored higher peaks in the viability of eggs and nymphs, respectively. Article III: objective was to evaluate the resistance to scale cochineal in different species of forage palm cultivated in vitro. The results listed the species of palm Nopalea sp. micropropagated as resistant to D. echinocacti and O. stricta micropropagada susceptible to scale cochineal, in addition the subcultures favored the biological development of D. echinocati.

The objective of this study was to verify if methionine supplementation in high temperature heat stress situations can minimize the deleterious effects on egg production in Japanese quails. For this purpose, 504 Japanese quails in production phase (second cycle) were used, distributed in a completely randomized design in a 3x4 factorial scheme, with three levels of methionine (100%, 110% and 120%) and four temperature ranges (20, 24, 28 and 32°C). It was first evaluated by immunohistochemical positivity and gene expression by real time PCR whether the calcium transporters, calbindin-D28k and TRPV6 acting on calcium uterus absorption, resorption and deposition, respectively. in duodenum and jejunum, kidney and uterus would be changed under such conditions (heat stress and methionine supplementation). It has been seen that methionine supplementation generally does not increase the positivity or gene expression of both genes in the aforementioned tissues, thus not reversing the deleterious effects in cases of heat stress. Exception to the uterine glands, which presented in immunohistochemistry, a higher positivity in animals supplemented at temperatures of 20 and 32ºC, evidencing the positive effect of supplementation for production of such birds, especially at temperature already considered heat thermal stress, such as that of 32ºC previously mentioned. Morphometric studies of the digestive system (height and width of the villus, crypt depth, villus: crypt ratio, villus area, number of goblet cells, stock) were also performed for the first time in heat stress quail and methionine supplemented. hepatic glycogen and steatosis) and breeding (height of uterine primary folds and number of secondary folds), which did not present significant results upon methionine supplementation, since the significant results were obtained at thermoneutral temperatures for the birds. It is concluded that the use of methionine supplementation is justifiable, with the objective of reversing the deleterious effects on the production of laying quails subjected to thermal stress, as there were alterations of calbindin and TRPV6 in the magnesium and kidney, production sites. eggshell and calcium resorption respectively, reversing part of the deleterious effects caused by heat and thus proposing improvements in the quality and production of these birds.

This study aimed to evaluate the proliferation of enterobacteria, especially E. coli, in spineless cactus and to verify its association with cases of diarrhea in sheep, as well as to analyze the response of these animals when fed with rich diets spineless cactus chopped hours before supply. In the in vitro test, it used two spineless cactus cultivar forage (Nopalea cochenillifera Salm Dyck e Opuntia fícus-indica Mill), each cultivar being chopped into particles of approximately 4 cm2 and 2 cm2 and allocated in a controlled environment for up to 24 hours. The completely randomized design was used in a 2 x 2 x 4 factorial arrangement, with 2 varieties de spineless cactus, 2 particle sizes and 4 evaluation times (0, 6, 12 and 24 hours after chopped the spineless cactus). The variables analyzed were: internal and external temperature, short-chain fatty acids (SCFAs) and microbial proliferation data by counting lactic acid bacteria (LAB), enterobacteria and Escherichia coli, most likely number (MLN) total coliforms and biochemical profile tests of E. coli colonies. In the in vivo trial, 15 lambs were used, distributed in a completely randomized design (CRD) composed of three treatments, chopped spineless cactus and immediately supplied to the animals; spineless cactus chopped eight hours before provided to animals and spineless cactus silage with five replications per treatment, consisting of five replicates. The total experimental period lasted 31 days, 10 of which to adapt the animals to diets and installations. The variables analyzed were dry matter intake, total weight gain, fecal scores, physiological variables, enterobacteria in Petri dishes. The data were submitted to analysis of variance (ANOVA), when significant (P < 0.05), the differences between means were analyzed by t-Student and Tukey tests, considering 5% of probability. In the in vitro trial, it was possible to observe a higher internal temperature of the evaluated material, when the varieties were submitted to smaller particle size (2 cm2), while the SCFAs increased until 12 hours after chopped, reducing at 24 hours. Higher enterobacterial and LAB counts were possible at both 12 and 24 hours after spineless cactus chopped with 2 cm2 particle in both varieties. However, the highest number of LAB detected was at 6 hours (4.65 CFU/g) and 12 hours (5.05 CFU / g). The hemoglobin of the animals varied from the first day (86.73 g/ dL) to the 21st day (77.26 g/ dL), however, the most important variable, the globular volume, had no significant effect. Sheep fed with chopped spineless cactus eight hours before supply had the higher fecal enterobacterial count on the 21st day of collection (8.48 CFU/g), while animals fed with xvi silage had lower values (4.95 CFU/g). Among the enterobacteria isolated in the feces, the presence of E. coli was confirmed by the biochemical profile test, an expected result, as these are common organisms of the gastrointestinal tract. Thus, it can be concluded that spineless cactus management influences the development of total and fecal coliforms, especially when chopped at 2 cm2 and exposed to the environment for periods longer than seven hours, and the bacterial population can be controlled with the use of spineless cactus in the form of silage.

The education focused on the critical and autonomous thinking of the individual is the main instrument for the emancipation of subjects and for the transformation of society. Based at this theory, and in view of the educational possibilities emerged from the use of technological resources, this research was outlined. In this research, this theory is associated to the educational possibilities arising from the use of technological resources, especially the production and consumption of the digital genre fanfictions, in a multiliteracies perspective materialized through literary and digital literacy, in the construction of a pedagogical practice based on in the students' autonomy of thought and criticality through critical reading and creative writing. We had as general objective to analyze and prove the potential of the use of fanfics as a pedagogical resource for a practice of reading and writing critical and emancipatory. It is a qualitative bibliographic research, scientific support for the study of emancipation, multiliteracy and fanfictions, and participant. As epistemological approach, we define historical and dialectical materialism based on Triviños (2015) and Gamboa (2012), to apprehend education as an emancipatory phenomenon amidst the economic-political determinants that today shape school education as an uncritical transmission space of accumulated knowledge. Through open questionnaires and participant research — development of a pedagogical proposal with the use of fanfictions in a public school in João Pessoa / PB —, we obtained the necessary information for object analysis. Data analysis, based on dialectical hermeneutics with theoretical foundation in Minayo (2002; 2009; 2010), revealed three empirical categories: appropriation, authorship and autonomy of thought. The research makes it possible to state that the pedagogical use of fanfictions provides a space for interaction, creativity and autonomy of thought to the students, enabling them to develop, through the synergistic relationship between school and technology, real experiences of productive and collective use of the language that corroborate for their emancipation.

The present research aims to analyze if the Ombudsman from Federal University of Paraiba has acted as an instrument that allows the participation and social control of the academic community in the university management. Thus, the researcher conducted a survey on the evolution of the Brazilian State and the administrative reform, which it went through, including the transition from the bureaucratic State to the managerial one. Reaching the models of democratic and participatory management, in which transparency is a rule of administrative behavior and there is the possibility of exercising social control over the acts of the State by the community, supported by the Access to Information Law. In this context, the public ombudsman, as well as the university ombudsman act as interlocutors between the citizen and the administration. Regarding the adopted methodology, the research was classified as qualitative, based on the phenomenological method, used to investigate the lived experience. Data gathering involved documentary analysis of instructional manuals from the Federal Comptroller General's Office (CGU) and the National System for the Evaluation of Higher Education (SINAES); management reports issued by the Permanent Evaluation Committee (CPA) and the Ombudsman's Office from UFPB; related legislation; as well as the application of semi-structured interviews with teachers, technical-administrative servers, students and the UFPB's ombudsman. To interpret the results, we used the technique of content analysis. The results showed that the UFPB Ombudsman presents problems related to the infrastructure, lack of evaluation of its activities, as well as scarcity of disclosure of its existence and its performance. As a suggestion for improvements, in order to make the UFPB's Ombudsman's Office an instrument of participation and social control available to the academic community, the research proposes the implementation of an effective user evaluation system, stronger advocacy actions that also involve the Administration of the University, change of the room where the Ombudsman works and improvements in its website.

This work presents the design of a robust controller with the main objective of damping electromechanical oscillation modes (MOE) in power systems of three areas, seeking to achieve the robust stability of the system. Techniques for analysis and design of multivariate frequency domain controllers are used to verify the possibility of obtaining robust control with decentralized reduced-order controllers. In order for the controllers to achieve robustness, it is necessary to select the most significant input-output pairs for the system. For this purpose, analysis techniques were applied to a load-frequency system of three areas. The controller is of type H_∞ and the optimization method applied, to obtain the robust control of the system with uncertainties, was the tabu search.

The Safety Culture (SC) of a company has a direct influence on its Work Safety and Health Management System (WSHMS), since it is consistent with the involvement, practice and values of all the members of the organization and with the performance of the system. There are few studies on the influence of SC on Brazil organizations, however, these studies are necessary for the brazilian reality, since the indexes of diseases and accidents resulting from work are significant, as can be seen between the years of 2013 and 2015 there were 2,050,598 work accidents, of which 6.81% correspond to the food and beverage processing sector. In this perspective, this study aimed to investigate the SC maturity stage of a beverage industry. In order to reach this objective, qualitative-quantitative research was used, whose data collection instruments were based on the model of Gonçalves Filho. To characterize the work environment, an observational plan with a structured road map was used to identify the place where the health and safety issues of the organization are dealt with and the occupational hazards of each work environment. In order to know the SC maturity stage of the managers of the company's WSHMS, an interview was conducted using the Collective Subject Discourse method to analyze the results. The managers were framed in the bureaucratic and proactive stages, being the bureaucratic the predominant stage. To know the maturity stage of SC of the employees, questionnaires composed of 20 variables were applied to a sample of 130 respondents, using descriptive techniques and Factor Analysis (FA) to quantify the data. In the descriptive and individual analysis of the 20 variables of SC, it was verified that 6 variables obtained positive perception and 14 variables negative perception. Among the dimensions of the Gonçalves Filho model, the dimension 1 (Information) and 2 (Employee Involvement) were those that presented the highest levels of satisfaction, in which their variables are in the proactive maturity stage, except for the variable E4 of the dimension 1. Dimension 2 (Organizational Learning) was the one that stood out about the dissatisfaction, being its variables between the pathological and reactive stage. Through FA, 4 factors with total explained variance of 71.87% were found, these factors being representative according to the value of the variance explained by each, the factors were named in Information and Employee Involvement, Commitment, Organizational Learning and Engagement with the Safety of Work, with the possibility of improving the model used in this research with substitutions of the dimensions by the factors found. Through the factorial analysis it was also possible to verify that the variables presented strong and significant correlations to measure the degree of SC maturity. It can be concluded that the company is not in an exact and well defined stage of SC maturity for all, demonstrating which aspects need improvements for the efficient development of WSHMS for the prevention of accidents and occupational diseases.

Water scarcity grows by the day, especially in the semiarid regions. As a result, the amount of groundwater used in agriculture is strictly limited, and it has become necessary to explore alternative sources of water. The objective of the present study was to evaluate the potential of treated wastewater in the recovery of fertility of an anthroposol and in the vegetative growth of forage and forest palm, as well as to determine the basal respiration, carbon of the microbial biomass and metabolic quotient of an anthroposol year with wastewater irrigation. The experiment was conducted in a 780m2 area in Paraíba Semiarid in a randomized block design with ten replications, three plant species and three treatments, corresponding to the type and volume of water used (T1 = 500 ml of water supply -AA , T2 = 500 ml of wastewater -AR , T3 = 1000 ml of wastewater -AR). The experiment was carried out in an agroforestry system with 1560 forage palm rackets: Mexican elephant ear ( Opuntia tuna ) and 195 seedlings of 2 forest species : Sabiá (Mimosa ceasalpinifolea Benth ) and Aroeira Branca ( Myracrodruon urundeuva Allmanha) planted in double row. Biometric variables were investigated in the forage palm and in the sabiá forest species. Soil was collected before and after irrigation and analyzed for chemical and biological attributes. In the chemical parameters of the soil, significant contrasts were observed only for pH, Organic Matter, CTC, and Sum of Bases. The pH Initial was classified as neutral, changing to a weak acidity after treatment application, being more relevant between the initial soil pH (pH 6.9) and the addition 500 ml AA weekly (pH 5.9 ). MOS contents increased significantly after AR use. Regarding CTC, it was found that the plots that received the RA doses presented the highest values, when compared to the plots that received AA. Regarding the vegetative growth, the treatment with 1000 ml of wastewater weekly, responded better in all variables of forage palm , where it obtained a final average of 36.2 cm. The basal respiration of the soil did not respond significantly to the treatments, the biomass carbon was higher in the area with forest species, however the metabolic quotient had no significant differences between treatments. Regarding the chemical properties of the soil, the wastewater had greater influences on soil pH and organic matter, showing to be a promising alternative for the recovery of the productive capacity of the soil, mainly by the increase of the MOS. The effect on forage palm growth was greater on the 1000 ml treated wastewater slide, the 500 ml and 1000 ml week treated wastewater slides did not promote differences in the height and diameter growth of the thrush. The area under forest vegetation stood out in relation to the palm, possibly due to the larger contribution of organic residues from the plant itself, serving as a source of nutrients to the soil microbiota. Soil biological properties: basal respiration, biomass carbon and metabolic quotient were not directly influenced by the treatments.
