The Federal Institution for Education, Science and Technology, in its historical path, has been living different changes. The transformations occurred along the way have been determined by coercive forces from the institutional environment, which has became more and more broad and complex throughout the time, obtaining diverse characteristics and new elements such as non institutional factors1 which started to contribute with the other changes. In this context, this work aims to study the isomorphic practices of the managers in the institutional changes process of the IFRN in 1998 and 2008, as of a theoretical coevolutionary perspective (CHILD; RODRIGUES; LEWIN; CARROL; VOLBERDA, 2003). This theory brings a new point of view for the organization analysis to the organizational studies, since it offers a non deterministic and non linear lection of the evolution process, which means, a coevolution. Thus, the organizations and their institutional and non institutional environment auto evolve, auto organize and auto reproduce. Therefore, the institutional and non institutional factors of the macro environment keep a continuous interdependence relationship with the organizations. For the means of this study, it is important to understand that is impossible to comprehend the object, the isomorphic practices, without considering that the previous institutional changes and its evolutions, its continuations and discontinuations, important in the coevolution process. As such, to call upon the institutional historical track is a fundamental aspect to materialize this study, for the recursive movement is indeed present in the coevolution. Another important point to make this research effective is that it is not possible to abdicate from the hologramatic view2 of this study, which considers the object, the isomorphic practices, part of the whole and this whole is also in the parts, therefore it is impossible to comprehend the object of study outside the context where it belongs. With this, as of the objective previously proposed, it is necessary to describe the characteristics of coevolution of the institutional changes related in 1998 and 2008; analyze the dynamic of the isomorphic mechanisms in its respective institutional change process; and describe the lessons learned which the isomorphic practices left to the IFRN, regarding its benefits and difficulties. All these transformations happened through coercive forces3 of the institutional environment. As of the Nineties, these forces became stronger, the environment became broader and more complex, with the emergency of new environmental factors. This study proposed to study the managing process and its practices, related to the micro environment, although it is required to articulate these actions, the demands and requirements from the macro environment. To make this research effective, semi structured interviews have been conducted with the managers who participated in both institutional change processes. In the results analysis, it has been possible to verify the particularity of each change, the one from 1998 with a strong normative action of the managers against coercive forces from the government for the search of recognition and the institutional legitimation and the one in 2008, which has been characterized by the normative action by managers in agreement with the coercive forces from the government, in favor of the government policy for the technological professional education. However, the results analysis it is possible to notice the evidence of a belonging feeling from the interviewed managers

The aim of this study was to analyze the social representation of the sensible among teachers of the Federal Institute of Education, Science and Technology of Rio Grande do Norte, attempting to identify its constituents and understand the dynamics that gives functionality to your organization. The study is significant considering that the professional conduct can not be delineated in its complexity without unraveling the social representations that teachers themselves have of their being and doing professional. The theoretical and methodological framework of the research is the theory of social representation. 107 teachers from various backgrounds participated. To collect the data were used as instruments : a questionnaire listing, which subsidizes the characterization of the subjects , the TALP - technique of free association of words ( ABRIC , 1994) , the PCM - Procedure for Multiple Ratings ( ROAZZI , 1995) ; questionnaire redemption of sensitive memories of the subjects in their school experiences of childhood , adolescence, youth and teaching practice . The PCM data, in which the slogan was directed at rating Give class, were submitted to multidimensional statistical analysis. Already TALP was analyzed by EVOC 2000 software, the profile questionnaire received descriptive statistical analysis and the memories received the questionnaire analysis of thematic content, Bardin (2004). Taken together, the results point to a social representation of sensitive teaching (the game, the fun, the touch, the smile, the relaxation) are not in the classroom. The sensitive pure still fits in school, but only in the courtyard, on the playground, in the intervals, therefore, outside of space-time class, playful perch that lives in each of us is totally strange to this world of the classroom . After doing the Approximation of ideas , we realized three discourses evident in the reports of teachers : the discourse of Numbness in which we perceive the distance of the teacher in relation to sensitive component as a facilitator in the learning process , the discourse of Feeling , in which we can discern small approximation to the sensitive dialogues and proposed in this study , the speech of reflection in which teachers analyze, evaluate and establish a discourse on the importance of education in sensitive , but not actualize in their teaching practice

This dissertation proposes studying the issue of withdrawal undergraduate in physics at the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) and collaborate with suggestions for dealing with this problem. The first chapter begins with an overview of two significant problems in the Brazilian educational system: the high dropout rates in degrees in physics and the lack of teachers with specific training in this science. Then, we discuss the relevance of this research to the area of physics teaching, as well as justify its completion as part of a professional master's degree. After, we present a proper definition for the term withdrawal, which is based on the existing problem in the IFRN. And, in the same chapter, we explicitly the focus, the objectives and the methodological aspects of this work. The results obtained in our investigation are presented in next four chapters. In the second chapter of this dissertation, we present: a brief history of the creation of IFRN degree in physics, the functioning of this course and the foundation of classrooms 2004.2 and 2006.1. We also show a kind of map of the withdrawal of the groups investigated (the dropout rate was 84.4% in both groups) and an analysis of the relationship between the curricula of each of them and the number of dropouts. In the third chapter, we display a descriptive statistics of the students which dropout and found that the largest dropout occurred with students who are women, married, parents of one kid; workers, joined with a minimum age of 23 years and completed high school at least 6 years. Then in the fourth chapter, we reveal and discuss the students' reports on the causes of their dropout. From the data presented, we can say that the answer to the question "What was the main reason for your dropout?" Is mainly in personal injury claims: another option for upper-level course and lack of time to devote to the course. In the fifth chapter, we show the results related to teacher s opinions about the phenomenon in question. We detected three main causes for the abandonment, according to teachers: the lack of dedication, the lack of interest and lack of integration in the course. In the sixth and final chapter, we discuss the results and present our conclusion and the proposed report - the product of this dissertation, presented as Annex. This report contains mainly suggestions for curricular and institutional actions that can contribute to reducing the dropout degree in Physics in the IFRN. The main actions suggested are: implementation of the curriculum in disciplines, implementation of programs or actions to combat this poor content of basic training, implementation of specific programs or actions for the student worker, and dissemination of IFRN degree in physics in schools through seminars or workshops

The scope of this Dissertation is propose the teaching of the evaporation based on the approach Science, Technology and Society (STS) because we believe that this type of approach is able to provide students with a more critical and conscious learning about science. Moreover, with this search, it´s possible to show for students the importance of role to play for them as citizens in decision making aimed to benefit all who are part of the community to which they belong. From this perspective, broached the theme evaporation in a region characterized by constant lack of water for consumption, the municipality of Santa Cruz/RN because, despite the creation of dams to regulate the flow of rivers and increase the availability of water during periods of scarcity, we know that these reservoirs have a large free liquid surface allowing high water loss by evaporation. Thus, evaporation affects the performance of reservoirs for water supply and irrigation, being a phenomenon of particular interest to study. To this end, a questionnaire in order to identify students' preconceptions on the subject was applied. Was then prepared and conducted a workshop geared toward students majoring in Physics Campus Santa Cruz, Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN). The completion of the workshop served as a space for discussion of the topic within the context of the municipality of Santa Cruz/RN. As a product, we suggest to physics teachers a guide with recommendations to be taken into account when they teach this subject

Analisa as práticas de mediação desenvolvidas nas bibliotecas universitárias pelos bibliotecários diante das tecnologias digitais. Para tanto estabelece como objetivo geral analisar de forma comparativa, o impacto e mediação das tecnologias digitais no funcionamento de bibliotecas Universitárias de Portugal e da região Nordeste do Brasil. Integraram esta pesquisa 10 universidades federais brasileiras e 12 universidades públicas portuguesas, com um total geral de 115 bibliotecários, que são os sujeitos participantes. É uma pesquisa qualitativa que adota o método quadripolar – recomendado para os trabalhos desenvolvidos no âmbito das Ciências Sociais Aplicadas, e em especial na área de Ciência da Informação. Através da interação entre os polos: epistemológico, teórico, técnico e morfológico, que fundamentam este método, houve o fortalecimento e a fluidez das questões estudadas. Os resultados dos questionários aplicados aos bibliotecários, bem como da análise dos sítios das bibliotecas pesquisadas, foram interpretados através de um alicerce teórico baseado em três pontos principais: as questões paradigmáticas que envolvem a área de Ciência da Informação, a análise da mediação pós-custodial informacional e científica e as Tecnologias de Informação e Comunicação presentes nas bibliotecas. Como principais resultados vemos que o impacto das tecnologias digitais nas bibliotecas universitárias é considerado pelos bibliotecários brasileiros e portugueses como positivo, com ênfase em dois pontos: a inovação dos suportes de informação e a autossuficiência dos utilizadores. A maior diferença se percebe em relação ao aspecto social, através de uma maior preocupação entre os bibliotecários brasileiros com as barreiras informacionais causadas por questões econômica, social e educacional e sentido com menos intensidade pelos bibliotecários portugueses, que ascendem as tecnologias digitais com mais facilidade. De forma conclusiva, a análise do impacto e a mediação das tecnologias digitais nas bibliotecas pesquisadas, apontam para uma evolução nas práticas mediadoras das bibliotecas universitárias de Portugal e do Nordeste do Brasil e uma convergência laboral entre os bibliotecários portugueses e brasileiros.

This paper comprises an investigation on the influence of the variable family backgrounds (father school level, mother school level and family income) over the pupil s performance in admissions examination (entrance test or PROITEC) at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN). From that point of view, the main goal of this research is to analyze the influence of the family background as a determiner of the pupil´s performance in the access to Technical and Professional education at IFRN. Secondary data were used from two databases (entrance test and PROITEC) adding up to 19.226 observations to the vacancies offered in the year of 2013. Aiming at achieving the proposed goal, a conceptual model composed of three hypothesis was developed. The results were presented in four stages: stage I presentation of the descriptive statistical results of the two databases; stage II separation of the campi in clusters; stage III analysis of multiple regressions; stage IV analysis of the logistics regressions. Two statistical tests were used to validate the hypothesis: T-test and Wald test. Hypothesis 1 and 2 were confirmed and H3 was refused. The results presented favorable causal connections to the family income and the father school level variables (with bigger effect for fathers with a higher education degree). The mother school level variable did not provide statistical significance for this research. Based on this result, after this work, this institution is to develop a strategic plan to assist in the success rate of students preparing diagnoses in order to diminish the effects of the variables that impacted negatively

Recent research has revealed that the majority of Biology teachers believe the practice of experimental activities as a didactical means would be the solution for the improvement of the Biology teaching-learning process. There are, however, studies which signal the lack of efficiency in such practice lessons as far as building scientific knowledge is concerned. It is also said that despite the enthusiasm on the teachers‟ part, such classes are rarely taught in high school. Several studies point pedagogical difficulties as well as nonexistence of a minimal infrastructure needed in laboratories as cause of low frequency in experimental activities. The poor teacher performance in terms of planning and development of classes; the large number of students per class; lack of financial stimulus for teachers are other reasons to be taken into account among others, in which can also be included difficulties of epistemological nature. That means an unfavorable eye of the teacher towards experimental activities. Our study aimed to clarify if such scenario is generalized in high schools throughout the state of Rio Grande do Norte Brazil. During our investigation a sample of twenty teaching institutions were used. They were divided in two groups: in the first group, five IFRN- Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte schools. Two of those in Natal, and the other three from the country side. The second group is represented by fifteen state schools belonging to the Natal metropolitan area. The objectives of the research were to label schools concerning laboratory facilities; to identify difficulties pointed by teachers when performing experiment classes, and to become familiar with the conceptions of the teachers in regarding biology experiment classes. To perform such task, a questionnaire was used as instrument of data collecting. It contained multiple choice, essay questions and a semi-structured interview with the assistance of a voice recorder. The data analysis and the in loco observation allowed the conclusion that the federal schools do present better facilities for the practice of experimental activities when compared to state schools. Another aspect pointed is the fact that teachers of federal schools have more time available for planning the experiments; they are also better paid and are given access a career development, which leads to better salaries. All those advantages however, do not show a significantly higher frequency regarding the development of experiments when compared to state school teachers. Both teachers of federal and state schools pointed infra-structure problems such as the availability of reactants, equipments and consumption supplies as main obstacle to the practice of experiments in biology classes. Such fact leads us to conclude that maybe there are other problems not covered by the questionnaire such as poor ability to plan and execute experimental activities. As far as conceptions about experimental activities, it was verified in the majority of the interviewees a inductive-empiric point of view of science possibly inherited during their academic formation and such point of view reflected on the way they plan and execute experiments with students

This work addresses the relationship between University-Firm aims to understand the model of shared management of R&D in petroleum of Petrobras with UFRN. This is a case study which sought to investigate whether the model of cooperation established by the two institutions brings innovation to generate technical-scientific knowledge and contribute to the coordination with other actors in the promotion of technological innovation. In addition to desk research the necessary data for analysis were obtained by sending questionnaires to the coordinators of projects in R&D at the company and university. Also, interviews were conducted with subjects who participated in the study since its inception to the present day. This case study were analysed through the Resource-Based View and Interorganizational Networks theory. The sample data also stands that: searches were aligned to the strategic planning and that 29% of R&D projects have been successful on the scope of the proposed objectives (of which 11% were incorporated into business processes); which was produced technical and scientific knowledge caracterized by hundreds of national and international publications; thesis, dissertations, eleven patents, and radical and incremental innovations; the partnership has also brought benefits to the academic processes induced by the improved infrastructure UFRN and changing the "attitude" of the university (currently with national prominence in research and staff training for the oil sector). As for the model, the technical point of view, although it has some problems, it follows that it is appropriate. From the viewpoint of the management model is criticized for containing an excess of bureaucracy. From the standpoint of strategic allocation of resources from the legal framework needs to be reassessed, because it is focused only on the college level and it is understood that should also reach the high school given the new reality of the oil sector in Brazil. For this it is desirable to add the local government to this partnership. The set of information leads to the conclusion that the model is identified and named as a innovation of organizational arrangement here known as Shared Management of R&D in petroleum of Petrobras with UFRN. It is said that the shared management model it is possible to exist, which is a simple and effective way to manage partnerships between firms and Science and Technology Institutions. It was created by contingencies arising from regulatory stand points and resource dependence. The partnership is the result of a process of Convergence, Construction and Evaluation supported by the tripod Simplicity, Systematization and Continuity, important factors for its consolidation. In practice an organizational arrangement was built to manage innovative university-industry partnership that is defined by a dyadic relationship on two levels (institutional and technical, therefore governance is hybrid), by measuring the quarterly meetings of systematic and standardized financial contribution proportional to the advancement of research. These details have led to the establishment of a point of interaction between the scientific and technological-business dimension, demystifying they are two worlds apart

With the increasing offer of education services in Brazil, it is necessary to evaluate the quality of service in education, especially in those institutions for vocational education which have a greater interaction with the labor market, in order to form qualified professionals and meet the growing demand that the country has today[A1] . In Brazil, the evaluation of the quality of library services has influenced the assessment of educational institutions and in this context, there needs to be a process to monitor the quality of services provided by libraries. However, the service is not done in a single moment and thus to a more detailed assessment it needs to be measured and evaluated each different time the customer uses it. Therefore, the aim of this work consists in measuring the quality in every moment of truth of a cycle of library services to assess which are the most relevant moments in the client's perspective at the library of the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) Campus João Câmara in building the overall quality of service. In the literature review, internal secondary sources were used, from the database of the institution studied, and also external sources, through literature in books, articles, dissertations, theses and journals on compost quality, service quality, cycle services, measuring quality, satisfaction, teaching activities, and on library services specifically. We applied a questionnaire to students in the library based on models of quality measurement SERVPERF and SERVQUAL and its variations such as SERVQUAL pondered and SERVPERF pondered . Through analysis based on concepts of reliability and validity of measuring instruments, it was found that the SERVPERF model is the instrument that most closely matches the dimensions of quality assessed in the library with customer satisfaction measured by the questionnaire. From there, the search results as measured by statistical techniques of analysis, indicated that the initial and final moments of truth of the cycle of service quality had the greatest influence on overall customer satisfaction with the library service

Brazil, one of the largest agricultural producers in the world, has managed in recent years to significantly improve its production. However, in response to this advance in the agro-industrial sector, the generation of agro-industrial residues has also increased. New technological alternatives have to be implemented in order to bring economic and rational use of this material and drying is one of the possible choices. Considering the great importance that bioactive compounds present for food science and technology, this research aims to evaluate the air-drying process of acerola residue in a tray convective drier under controlled temperature (60, 70 e 80ºC), air velocity (4.0, 5.0 e 6.0 m/s) and material width (0.5, 0.62 e 0.75 cm) by applying an experimental planning 23 + 3. Based on that, the impact on physical-chemical characteristics, color, bioactive compounds concentration and antioxidant activity of dried acerola waste was evaluated, having the in natura and freeze dried waste as control groups. Dried acerola residue presented natural pigments, mainly carotenoids (143.68 - 68.29 mg/g) and anthocyanins (290.92 - 90.11 mg/100 g), which explain the red and yellow instrumental color parameters observed. The acerola residue powder is also rich in phenolic compounds (3261.11 -2692.60 mgGAEeq/100g), proanthocyanidins (61.33-58.46 eq/100g), ascorbic acid (389.44 739.29 mg/100 g) and DPPH antioxidant activity (20.91 24.72 μg Trolox eq/g). Results show decreased concentration of phenolic compounds, anthocyanins, carotenoids, proanthocyanidins and ascorbic acid caused by the air-drying process. However, even after the observed drying losses, the acerola residue powder can be considered a high value food ingredient, considering the high bioactive compounds concentration found in the final product, as well as the colorimetric characterization and microbiological stability of the dried powder
