Ação pública na formação e transformação do destino turístico de Porto de Galinhas: um estudo dos referenciais no período de 1970 a 2010

The central interest of this thesis is to comprehend how the public action impels the formation and transformation of the tourist destinies. The research was based on the premise that the public actions are the result of the mediation process of state and non-state actors considered important in a section, which interact aiming for prevailing their interests and world visions above the others. The case of Porto de Galinhas beach, in Pernambuco, locus of the investigation of this thesis, allowed the analysis of a multiplicity of actors on the formation and implementation of local actions toward the development of the tourism between the years 1970 and 2010, as well as permitted the comprehension of the construction of the referential on the interventions made. This thesis, of a qualitative nature, has as theoretical support the cognitive approach of analysis of the public policies developed in France, and it has as main exponents the authors Bruno Jobert and Pierre Muller. This choice was made by the emphasis on the cognitive and normative factors of the politics, which aspects are not very explored in the studies of public policies in Brazil. As the source of the data collection, documental, bibliographic and field researches were utilized to the (re)constitution of the formation and transformation in the site concerned. The analysis techniques applied were the content and the documental analysis. To trace the public action referential, it started by the characterization of the touristic section frontiers and the creation of images by the main international body: the World Tourism Organization, of which analysis of the minutes of the meetings underscored guidelines to the member countries, including Brazil, which compounds the global-sectorial reference of the section. As from the analysis of the evolution of the tourism in the country, was identified that public policies in Brazil passed by transformations in their organization over the years, indicating changes in the referential that guided the interventions. These guidelines and transformations were identified in the construction of the tourist destination of Porto de Galinhas, of which data was systematized and presented in four historical periods, in which were discussed the values, the standard, the algorithms, the images and the important mediators. It has been revealed that the State worked in different roles in the decades analyzed in local tourism. From the 1990s, however, new actors were inserted in the formulation and implementation of policies developed, especially for local hotelkeepers. These, through their association, establishes a leadership relation in the local touristic section, thereby, they could set their hegemony and spread their own interest. The leadership acquired by a group of actors, in the case of Porto de Galinhas, does not mean that trade within the industry were neutralized, but that there is a cognitive framework that confronts the actors involved. In spite of the advances achieved by the work of the mediators in the last decades, that resulted in an amplification and diversification of the activity in the area, as well as the consolidation at the beach, as a tourist destiny of national standout, the position of the place is instable, concerned to the competitiveness, once that there is an situation of social and environmental unsustainability

Educação - Corporeidade - Lazer: saber da experiência cultural em prelúdio

In the passage of life, the labyrinth of songs and corners are propitious ways for a better comprehension, perception and incorporation of learnings that emerge from our subjectiveness in a magic caught by senses. Eyesight, taste, hearing, touch and smell in communication with the world, put us in front of cultural diversities. The ludicity accumulated by experiences promote the flow of hilarious and concrete discoveries that express themselves in work and leisure demonstrations. Such reflections emerge indicators to the problematic construction centralized in the incorporation of cultural experience knowledge to the formation process and professional interventions in this rule and area. From this significant problematic, aiming to deepen studies, we favored leisure as field of investigative production in full expansion. This, for sure, was an exercise of qualification that guided us through meander of education and made us dip into studies about the corporeity. A research in which the scenery was painted and constructed with the complicity of the culture lived with shine, colors, rhythm and drummings of one of the most present cultural cycles: carnival. Recognized as a stimulant for beauty, participation, socialization, and helped us to enter in the essence of gestures and expressions of corporeity, to think, elaborate and socialize a critic-scientific knowledge which, appropriating from the rhythm of colors, of sounds, of tonalities, of senses and of meanings impregnated in the web of life. All these things seduced the researcher, making imagination flow amid ludic-creative dialogues with the imaginary of researchers creation and production in the rule and area of leisure, education and corporeity. Option that made us outline as objective to investigate and interpret how leisure teachers-researchers, from their studies, researches and interventions, locate and incorporate the knowledge from cultural experience to the formation process and intervention of professionals in this rule and in this area, emphasizing the contributions from this knowledge to fence and qualify this praxis. So, as living each cultural scenery, each epistemological contribution was feeding the production with images of the different versions of the Brazilian breedings, creating and raising expectations and new discoveries and newcomers. With the seriousness of a scientific study, we lived an xxiii academic experience with complex intensity, rigor and coherence, eliminating, step by step, the risks and limitations always present in a work of this magnitude. However, we weren t, even for one moment, alone. Our epistemic regard always maintained mediated by the principles of a methodological approach - the Etnomethodology, that while central guide provided us clues to unveil the lived world by our people-playful , in a universe of 15 members, that allowed themselves to comprehend, comment, analyze. This way, grasping the object in interactions arised and provoked by narrative interview, it was systematically dialected by (re) interpretation of images and formulations of people-playful, enriched by their beliefs, myths, conceptions and rituals inherent to knowledge from cultural experience, which each one attuned with Brazilian and international history, in a mixture of senses echoed from songs and tales. Inspired in drummings and percussions, clothing and choreographies of gestures and expressions, in mixtures produced in unit interactions in the multiplicity shown as necessary requests to the totality of life, with ludicity the rescue of the past, the conquest of present and the construction of future was the axle guide. This rich process of scientific creation made us realize that is possible qualify and empower the praxis in the rule and area of leisure incorporating the knowledge from cultural experience. What also becomes possible is the recuperation of objective revolutionaries and changing conditions of praxis itself with the view of strengthening and triggerment of vital elements in the rule and area of leisure. We also reaffirm that from this praxis emerge elements necessary to human formation in plenitude, by the appropriation of knowledge that guide the facing of challenges of a complex and plural world that valorize education, corporeity and leisure

Corpo e beleza: uma análise das produções da educação física, em nível de mestrado

Talking about body and beauty seems fairly familiar to physical education. We understand that the body language in the area provides many meanings over the appearance, beauty and aesthetics, thus requiring the need of criticism and the need to interrogate her to realize how physical education has been re-signified. For this purpose, considering the multiplicity of meanings that surround the body and beauty, we discussed the implications that this brings to the area of Physical Education, analyzing the conception of body and beauty in the studies in this area, at the masters level, from some questions: What conceptions of body and beauty have been discussed in the studies of physical education at the masters level? What is the relationship between the meanings of body and beauty products analyzed and identified in the models of beauty outlined in Physical Education? We understand the importance of this research and its contribution to the epistemological analysis of existing studies. And, mainly because there is a lack of studies that discuss these productions. For construction of this text and for our reflections, we rely on thoughts like David Le Breton, Claude Levi- Strauss, Michel Foucault, Maurice Merleau-Ponty, Ana Marcia Silva, Carmen Smith, Isabel Mendes, Karenin Porpino Nobrega and flounder. The present study is characterized as a qualitative research, and content analysis proposed by Laurence Bardin (1977) for data processing. The corpus was composed of eight essays in the area of Physical Education, published in the CAPES Theses Database for the period 2004 to 2008, selected from the subject and body beauty. The initial reading allowed us to select meaningful units and guide our discussions on two main themes, which make up the two chapters of the work. In the first chapter, entitled Body, beauty and culture, as evidenced understandings of body, nature and culture that are present in the work is considered. In the second chapter, Standard Body Transformations and beauty, we present the concepts of body and beauty found in the dissertation, focusing on the mutability of representations of the models of beauty in body singularities in the relations of power-knowledge and the importance given the body in society, especially with regard to physical education professionals. We have thus found that, considering the dissertations analyzed, the understanding of body and beauty has been resignified, when dealing with other aesthetic conceptions that consider the uniqueness expressed in the human body and the culture of which the individual belongs

Uma viagem aos saberes das formadoras de professores da Educação Infantil

This study aims to contribute with the professional development of the Trainers of childhood education teachers of the City Department of Education of Natal/RN, through a formation in context, trying to understand the teaching knowledge required in the practice of these professionals. The focus of the research is in teaching knowledge understood as the ideas, beliefs, conceptions, reasons, arguments, speeches that the trainers builds during his life (ALTET, 2001; PIMENTA, 2002; TARDIF, 2001; 2002). The study inserts itself in the qualitative approach of the educational research and the chosen methodology has characteristics of an inquiryaction. In the process, the following instruments had been used: questionnaires, press conferences, personal documents. The relevance of the present research is in achieving reflections concerning the role of the trainers of teachers, who needs to be seen as a mediator in the formation of teachers, in view of the fact that he interferes and is determinative in such a way in the formative process as in its results. The findings demonstrate that: a) the identity of the trainer is in a development process, what it is resembled to the effective situation of that, symbolically, the trainer exists, however, his attributions still are not enough clear; b) the teaching knowledge of the formation in the childhood education are related, among others points, primordially, to the function / role of the childhood education, child and teacher s point of view of this stage of the basic education; c) the Trainers teaching knowledge, concerning the teaching performance, ratifies the multiplicity of knowledge that the trainer must has, beyond the necessary complementarities and conciliation between the administrative and pedagogical aspects in the exercise of the function; d) the Trainers have knowledge that are according to the speech, consisting as declarative knowledge; e) there is a conflict between the teaching knowledge of the Trainers and the actions that are part of real life, generating contradictions between the formative saying and making

Um olhar estético sobre o telespetáculo esportivo :contribuições para o ensino do esporte na escola

The sportive television spectacle shows up like a media phenomenon which evidence performances and techniques that further on the community realized in the quotidian sportive practices into a show and play mixer, that more and more, sensibility the viewers. In this scenery , this research is about the relation between sportive television spectacle and viewer by the aesthetics perspective, and discussed the sport in the Physical Education context with the focus in the contributions to teaching in the school. The research, to the methodological view, uses the discuss analysis and realizes a qualitative study in two interdependent moments. In the first, analysis the dada collated in the Education, sport and television workshop. In the second, turns about TV images of sportive television spectacle to appreciated, to support a discuss of these phenomenon s aesthetics elements, looking for the relation established between the sportive television spectacle and viewer. The analysis s emphasis is in the sensations by sportive television spectacle, as well in the aesthetic elements problems promoted by this experience, from the two basics concepts, to know: the aesthetic and the synaesthetic perception. The analysis s corpus is composed by Esporte Espetacular TV program. Identify, in the sportive television spectacle appreciation, four big discuss axis of great importance between sportive television spectacle and viewer understanding: the relation space and time, the belonging feeling, the language interlacing, and beauty models. Understand in the analysis that, in the sportive TV scenery, occurs a construction image that seduces and involves the viewer through the aesthetics elements. From that discuss axis reflect about teaching sport in the school, main concern to the materialization a sport model only. Aims unfolding about space and time construction yet, and about the multiplicity language for to work in the school. Positions that no absolute rules, but that check the TV sport by the seduction promoted in the viewers through the aesthetics elements transmit

Entre saberes e práticas :a alfabetização de jovens e adultos no MOVA Belém

This research analyses the experience of the Alphabetization of Young and Adults Movement named Prof. Paulo Freire (MOVA Belém) in the time period 2001-2004. the study intends to reveal which knowledge/activities are constituent of pedagogical practices of popular alfhabetzers. It also intends to contribute with the registry in the history of alphabetization of young and adults in Belém, without any intention of making general the analyzed aspects. The research is characterized by the use of a qualitative approach of the type ethnographic, because it involves an analysis that considers at the same time the local and global aspects. It analysis documents produced in the period and uses semi-structured interviews for data construction. It tries to show living cues and experiences of the pedagogical activities found in the theoretical references of Brandão (2003), Freire (1979; 1987; 1992), Gadotti (1998; 2000), Ribeiro (1999; 2003), Santos (1995; 2000), Soares (1985; 1998; 2003) and other authors of alphabetization and popular education fields. This multiplicity of bibliographical and empirical references has produced a heterogeneous framework, that is much more complex and multifaceted than the one which would be constituted as the knowledge of the pedagogical, alphabetizer practice. It can not happen, however, an absolute concept that is clear and total that resumes significance and matter of the pedagogical, alphabetization practice of young and adults. So, the study establishes a relativism between them assuming as valid the ones that are of popular and democratic types. At last but not least, it intended to contribute to the history of the alphabetization of youngsters and adults in Belém with a popular education perspective without any pretension to turn the analyzed aspects into generalized ones

Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

Relações interpessoais no ambiente de trabalho da equipe de enfermagem: uma ação comunicativa

The current study strives to address the interpersonal relationships of the nursing team from the perspective of the communicative action, by contributing to the health work process. It aims to analyze the interpersonal relationships of the nursing team in its work environment. This is a descriptive study with a qualitative approach. Data collection wal held from interviews, guided by a script with open questions. The study was conducted at a state hospital in the city of Natal/RN/Brazil. The research subjects were the workers of the nursing team, including nurses, nursing technicians and nursing assistants, totaling 16 subjects. The capture of information was performed in April 2012. The project was approved by the Ethics Research Committee, under CEP/UFRN protocol n. º 262/11 and Certificate of Presentation for Ethical Consideration n. º 0289.0.051.000-11. The analysis was performed from the categories that emerged from the research through a dialogue with the authors studied in the theoretical framework of the Theory of communicative action , by Jürgen Habermas, as well as The changing in the world of work, by Ricardo Antunes, and Characterization of the team , by Marina Peduzzi. The outocomes point out that the interpersonal relationship of the nursing team is very troubled, with no interaction among the individuals involved in this process, among themselves and with other health professionals. We have developed a particular concept about team, which is comprised of three essential elements: multiplicity of individuals, common objective and heterogeneity. In the studied environment, it was realized the existence of grouping teams. The interpersonal relationship of the nursing can be a facilitator or an obstacle in the workplace in such a way that causes positive or negative consequences, both to the health workers, and to the sicks. In this context, the interviewees have intensified their viewpoints with regard to the weaknesses that permeate the nursing relationship, by pointing them more frequently than the strengths. The work conditions have signaled a failing situation, which is evidenced by the constant improvisation process before the lack of human and material resources, low wages, deficit in recognizing the nursing worker, and physical and emotional wear, by creating a professional exhaustion. The devaluation of the worker also became a strong factor for this study, because it was characterized a reason of job dissatisfaction, due to the lack of valuation policies, which should be prepared by the institution or, even, they are unknown by the worker itself. The worker participation in the design of these policies has emerged as a relevant factor. The poor work conditions lead the worker to a process of professional demotivation and dissatisfaction, by causing the feeling of devaluation within its work environment. Hence, it was found in this research that the lack of communication leads to situations of inadequate interpersonal relationships, which are creators of an unsuitable environment for the performance of the nursing team

Simulação da transferência de calor em amostras aquecidas por plasma

The processing of materials through plasma has been growing enough in the last times in several technological applications, more specifically in surfaces treatment. That growth is due, mainly, to the great applicability of plasmas as energy source, where it assumes behavior thermal, chemical and/or physical. On the other hand, the multiplicity of simultaneous physical effects (thermal, chemical and physical interactions) present in plasmas increases the complexity for understanding their interaction with solids. In that sense, as an initial step for the development of that subject, the present work treats of the computational simulation of the heating and cooling processes of steel and copper samples immersed in a plasma atmosphere, by considering two experimental geometric configurations: hollow and plane cathode. In order to reach such goal, three computational models were developed in Fortran 90 language: an one-dimensional transient model (1D, t), a two-dimensional transient model (2D, t) and a two-dimensional transient model (2D, t) which take into account the presence of a sample holder in the experimental assembly. The models were developed based on the finite volume method and, for the two-dimensional configurations, the effect of hollow cathode on the sample was considered as a lateral external heat source. The main results obtained with the three computational models, as temperature distribution and thermal gradients in the samples and in the holder, were compared with those developed by the Laboratory of Plasma, LabPlasma/UFRN, and with experiments available in the literature. The behavior showed indicates the validity of the developed codes and illustrate the need of the use of such computational tool in that process type, due to the great easiness of obtaining thermal information of interest

A vária máscara de Joana : melancolia em perto do coração selvagem

Entitled Joana s several mask: the melancholy in Perto do coração selvagem, the work is divided in six parts: the first one consists of the elaboration of a theoretical sketch about the melancholy that it offers the presuppositions that orientate the work, it is a short introduction about the study of the melancholy, a report until our time, the against-depressive ones and the arrival of the melancholy in Brazil and their particularities; the second part raises the theme of the melancholy, deepening its conception until what is called creative melancholy spread by Walter Benjamin, it serves as anchor for Clarice s writing and as a potential force for the processes lived by the characters of this writer; the third part examines Clarice Lispector s method emphasizing important points of production related to the theme of the melancholy, her style is the psychological analysis; the last one parts (fourth, fifth and sixth parts) are divided in topics that illustrate the conflicts, in most of the time contradictory, of the protagonist Joana, as well as, her difficult interaction with the things and the people that surround her. The fragmentary writing, the being's essential searches, the proximity with the death, the multiplicity of voices of feminine, De profundis, surrealist images, the incessant search for the thing , trips, epiphany, the flaw in the language, the taste of the badly, everything starting from melancholy - transformation and creation tool. The work about melancholy (Freud, Benjamin, Kristeva), it s place of ambiguous and contradictory movements. It is a trip that leads to several corporal and psychological sensations of Joana, enigma-scenes to be deciphered and conflicting images that make you wake up for a critical vision of the modern society. Since the beginning, something pulses without stopping, an incessant memory and the search for something that is lost. We are before recyclings of the interior/exterior, pain/pleasure, visions, abyss, ecstasy in the future and an exit through the melancholic light

Práticas discursivas e relações afetivas na contemporaneidade: o caso dos verbos ficar e namorar no contexto do vestibular da UFRN

This work is inserted to Applied Linguistic studies, concerned to the understanding that language is a social practice, bringing a qualitative research, discussing essential aspects that involve the subject and his/her discursive practice: signification and valuation. Due to this, we have elected as subject study, the sense and values attributed to the verbs make out and date searched on the articles written in the Vestibular 2005 process promoted by the Universidade Federal do Rio Grande do Norte (UFRN), that had the following instruction: In a relationship, is it better make out , just date , or, both, make out and date ? This research is based on the Circle of Bakhtin s dialogic theory, as well as in the notions of instability in the affective relationships nowadays and in the individualization and multiplicity of contemporaneous subjectivity. Those papers are important to analyze the meaning and values that the verbs make out and date present, nowadays, as expressions of an affective relationship and how this situation can interfere in the positions of subjectivity in a formal instance as a vestibular. Those textual productions reflect those relationships, confronting temporary ones, whose discuss is marked, in general, by social voices that evaluate to make out negatively and to date positively

O leitor universitário e a construção das práticas de ler e escrever textos impressos e digitais

The construction of a mapping of the practices of reading and writing printed and digital texts, declared by graduating students from the Bachelor s degree in Science and Technology (BCT), has provided us the analysis of the course they are making in such a socio-historical moment characterized by the revolution of the post-paper. In this sense, the general objective of this research is to understand how that construction works under the point of view of those graduating students. For this, our reflection has been guided by the search of answers for some questions which have presented to us: what reading and writing conceptions BCT graduating students have; what reading and writing practices those collaborators develop; what collections they declare to have access to; what differences they declare to have between printed and digital reading and writing along the different social roles they develop; what the reader/writer identity relations of those collaborators are. To achieving the plausible answers, we have gathered a corpus composed by texts of three genres of the argument order: academic profiles (or self-portrait), opinion articles and argumentative letters. Besides, we have made semi-structured interviews and questionnaires in the online tool of the Google Docs. The methodology which supports this academic work is the qualitative research (SIGNORINI; CAVALCANTI, 1998)of ethnographic direction (THOMAS, 1993; ANDRÉ, 1995) in Applied Linguistics (CELANI, 2000; MOITA-LOPES, 2006) and the theoretical contribution comes from the bakhtinian perspective of language conception (BAKHTIN [1929] 1981); the socio-historical writing construction (LÉVY, 1996; CHARTIER, R., 1998, 2002, 2007; COSCARELLI, 2006; CHARTIER, A., 2007; ARAÚJO, 2007; COSCARELLI; RIBEIRO, 2007; XAVIER, 2009; MARCUSCHI; XAVIER, 2010); from the studies of the pedagogy of the writing (GIROUX, 1997); from the literacy studies understood as sociocultural practice, plural and situated (TFOUNI, 1988; KLEIMAN, 1995; TINOCO, 2003, 2008; OLIVEIRA; KLEIMAN, 2008), from the studies about identity in postmodernity (HALL, 2003; BAUMAN, 2005). The results of the analysis have pointed at a multiplicity of reading/writing practices of printed and digital texts developed by the BCT graduating students due to the coexistence of the modality printed and that one derived from the new mobile devices. In that multiplicity, the prevalent idea of the collaborators is that there is a continuum between printed texts and digital texts (not a dichotomy), since the option of reading/writing printed texts or digital ones is always linked to specific communication situations, which involve participants, objectives, strategies, values, (dis)advantages, besides (re)creation of discursive genres in function of the mobile devices to which those collaborators have access in the different spheres of activities that they participate. All of that has caused a deep intersection in the identity traces of college students readers/writers in the 21st century which cannot be ignored by academic formation

O ensaio jornalístico na revista Veja: uma análise multidimensional

This work has as objective generality to make a multidimensional analysis in the genre journalistic assay, communicative genre that, beyond complex and multimodal, presents hybrid characteristics. Specifically, with the intention to propose defining criteria of the cited genre, this research looks for to establish differences and similarities between the assay and other genres of the same sphere, from the description and interpretation of used multimodal resources. The analysis of the formal, schematical and rhetorical resources identified in the formatting of the journalistic assay sample that the analyses are supported in the socio-semiotic and socio-rhetorical approaches. In the formal dimension, we contemplate elements that constitute design of the text, including the forms of representation from the typography, the colors, images, as well as the aspects communicative-linguistics: the modalization indices, the communicative operators and the category time; in the schematical dimension, we present the organizational structure, considering the rhetorical movements postulates for Swales (1990) and in the rhetorical dimension we observe the categories: who writes, for who it writes, on what it writes and where writes. The adopted methodologicals postulates are of qualitative nature and the procedure is documentary, data that in we are valid them written texts of this genre as analysis object. Corpus it is constituted by a composed sample for 14 extracted texts of a set of 173 propagated journalistic assays weekly for the magazine Veja, in the period between August of 2004 and January of 2008. The analysis of the data showed that the journalistic assay, object of this study, materializes through multiple symbolic representations and multiple subjects that turn since a small episode of the daily facts of great social relevance in the present time, of historical and cultural nature, nationwide or international. Used for the first time by Montaigne in 1580, to assign, in saying of the proper author, written fast on its life and historical events, which could nor be remembered later , the term `assay' was enriched with other specifications, of form to enclose the one that if they call scientific assay today, academic assay, journalistic assay and other types of specific assays. These denominations have to see with the enrollment of the members of diverse of practices communities, in virtue of the multiplicity of activities carried through in these spheres. The conclusions the one that we arrive had been the following ones: 1. the discursive genre is not a pure entity, in virtue of the multiplicity of situations where the sorts if insert in the social actions; 2. the institutions define the configuration of one definitive genre, also its proper assignment, since for backwards of all discursive genre a voice exists to discipline - institutional voice, and in the case of the assays for analyzed us, the institutional voice if it presents, really, as a defining trace; 3. the journalistic assay, for its multiple symbolic representations, multiple subjects and for passing explicit or implicit opinions of its author, resembles it other genres, being able, therefore, to be inserted in a colony of opinionatives genres

A Metafísica da luz em Marcílio Ficino.

The aim of the present dissertation constitutes to analyse the way in how light assumes the meaning of universal bond in the cosmovision of Marsilio Ficino, especially from his works Quid sit lumen, De Sole, De Amore and De Vita. The influence of Marsilio Ficino (1433-1499) in the history of occidental thought is impressive. Besides having translated to Latin the important texts of the neoplatonic tradition, Ficino presided over the Academy of Careggi, congregating important humanists in the top of the Renaissance. His treatises on love, beauty, light, magic and immortality of the soul have influenced strongly the production of other thinkers. The subject of light is of fundamental importance among his works since it is deeply related with all the other aspects of his philosophy. For him, light is spiritual emanation that perpasses everything without staining itself. Originated how the divine goodness, the light blows up in beauty in multiplicity, setting fire on the soul that truily contemplates it and that identifies whith it. The starting point of this loving relation between man and deity is, therefore, the physical world, that occults in itself the metaphysical light.
