Graph Analasys

Early psychiatry investigated dreams to understand psychopathologies. Contemporary psychiatry, which neglects dreams, has been criticized for lack of objectivity. In search of quantitative insight into the structure of psychotic speech, we investigated speech graph attributes (SGA) in patients with schizophrenia, bipolar disorder type I, and non-psychotic controls as they reported waking and dream contents. Schizophrenic subjects spoke with reduced connectivity, in tight correlation with negative and cognitive symptoms measured by standard psychometric scales. Bipolar and control subjects were undistinguishable by waking reports, but in dream reports bipolar subjects showed significantly less connectivity. Dream-related SGA outperformed psychometric scores or waking-related data for group sorting. Altogether, the results indicate that online and offline processing, the two most fundamental modes of brain operation, produce nearly opposite effects on recollections: While dreaming exposes differences in the mnemonic records across individuals, waking dampens distinctions. The results also demonstrate the feasibility of the differential diagnosis of psychosis based on the analysis of dream graphs, pointing to a fast, low-cost and language-invariant tool for psychiatric diagnosis and the objective search for biomarkers. The Freudian notion that ‘‘dreams are the royal road to the unconscious’’ is clinically useful, after all.

Sustentabilidade das empresas associadas à REDEPETRO-RN

The present study investigated the management of social, environmental and economic sustainability practices employed by 72 oil companies in Rio Grande do Norte state in Brazil associated to Joint Business Network for Enhancing the Competitive Ability of Suppliers of Goods and Services to the Gas and Oil Industry in Rio Grande do Norte (REDEPETRO-RN). Thus, our investigation aimed to determine the extent to which sustainability practices of companies associated to REDEPETRO-RN are developed through their own efforts or influenced by the Triple Helix interorganizational arrangement (governamental organizations, education and research institutions, and industries). The research instrument used was a questionnaire in order to map and characterize the sustainability practices. The research subjects were business owners and managers. The data collected supported the descriptive, correspondence and correlation analyzes. Were identified a greater emphasis of the companies surveyed in developing sustainability practices and greater economic influence of business organizations in the construction of sustainability status. It was concluded with confirmation of thesis of the REDEPETRO-RN arrangement exhibits the characteristics and functioning of a common Interorganizational Cooperative Arrangement, not those of a triple helix interorganizational arrangement, given that the influences exerted for the development of social, environmental and economical sustainability on the part of teaching and research institutions, and government and business organizations do not interact with one another sufficiently to create a virtuous circle of cooperation among the associated companies. By contrast, the Interorganizational Cooperative Arrangement plays an important role in strengthening the competitiveness of companies affiliated to REDEPETRO-RN, by combining different competencies in an attempt at supporting the adoption of sustainability practices, a role reinforced by the scope of PETROBRAS, which, due to its economic importance, has considerable weight in the managerial decisions of associated companies

Aceitação e uso de ambiente virtual de aprendizagem no contexto de um curso de capacitação para servidores públicos

This study aimed to examine how students perceives the factors that may influence them to attend a training course offered in the distance virtual learning environment (VLE) of the National School of Public Administration (ENAP). Thus, as theoretical basis it was used the Unified Theory of Acceptance and Use of Technology (UTAUT), the result of an integration of eight previous models which aimed to explain the same phenomenon (acceptance/use of information technology). The research approach was a quantitative and qualitative. To achieve the study objectives were made five semi-structured interviews and an online questionnaire (websurvey) in a valid sample of 101 public employees scattered throughout the country. The technique used to the analysis of quantitative data was the structural equation modeling (SEM), by the method of Partial Least Square Path Modeling (PLS-PM). To qualitative data was the thematic content analysis. Among the results, it was found that, in the context of public service, the degree whose the individual believes that the use of an AVA will help its performance at work (performance expectancy) is a factor to its intended use and also influence its use. Among the results, it was found that the belief which the public employee has in the use of a VLE as a way to improve the performance of his work (performance expectation) was determinant for its intended use that, in turn, influenced their use. It was confirmed that, under the voluntary use of technology, the general opinion of the student s social circle (social influence) has no effect on their intention to use the VLE. The effort expectancy and facilitating conditions were not directly related to the intended use and use, respectively. However, emerged from the students speeches that the opinions of their coworkers, the ease of manipulate the VLE, the flexibility of time and place of the distance learning program and the presence of a tutor are important to their intentions to do a distance learning program. With the results, it is expected that the managers of the distance learning program of ENAP turn their efforts to reduce the impact of the causes of non-use by those unwilling to adopt voluntarily the e-learning, and enhance the potentialities of distance learning for those who are already users

"Bordados do Seridó" : uma experiência etnográfica com as bordadeiras do município de Caicó-RN

The narratives that circulate Caicó tell us that the activity of embroidery would have come to town by the eighteenth century, by the Portuguese colonizers. Initially, the embroidery worked as a constitutive element in the formation of women, especially in the construction of the role of "talented ladies", was later characterized in a income generating activity moving strongly the informal sector of the local economy. In addition to source of income, the practice of embroiderers is redefining the craft tradition, transforming the embroidery on one of the symbols of identity of the city as it reaches other markets, carrying the name "Caicó embroidery". The research aims to investigate the dynamics of artisanal embroidery production, within the family circle and its consequences after its entry in the commercial sphere. It also seeks to investigate how the activity operates within a context in which the subjects (embroiderers and intermediaries) and their distinct negotiations trigger certain discourses, particularly those related to identity and authenticity on behalf of economic, political and cultural purposes

O desenvolvimento sustentável na ordem constitucional e sua promoção através do planejamento urbano

The man, being subject and object of their changes, has passed by many process to find a better life way. Since your existence, he finds to live in groups for make easy your life and make concrete yours desires. All by history, when the individual´s rights was establishment, collectives and lonely way, contribute for evaluate the relationship between individuals and they own, and them and state, which has a duty to those, positive or negative, depending on the case. The circle of fundamentals rights has been sustainable development and the concept of growth economy associated to the environment protection. This association reflect a apparent conflict between values very distinct, but the constitutional interpretation can be reunite both of them and make it live in harmony; values of environmental order and economical order can be exist together, as long as the state contribute to this. On the city, where the most of relationships happening, the urban plan appear how a effective way of sustainable development, finding the harmony between the growth economy and environment protection. To effective the socials functions of the city (inhabit, circulate, work and entertainment) and the citizen´s life quality, the city is the scenery that show how the urban plan, across established previously legal instruments, like the governmental public politics, to effective the right to development, right of third generation. The director plan how effective tool for local needs - obligation defined by Citizen Statute that contribute for the program linked defined by the urban plan. The state´s intervention on the private sector of citizen, and the restriction on their rights are be justified by the collective´s rights and their quality of life. So, in front the urban scenery has been the plan to make social functions of city, the healthy way of life, which is the sustainable development

Reflexões sobre a construção e evolução de conceitos geométricos nas séries intermediárias do ensino fundamental

This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of Volume of the Rectangular Parallelepiped, Area and Perimeter of the Rectangle adding a study of the Area of the Circle. The research was developed along with students from the 6th level of the Elementary School, in a public school in Natal/RN. The pedagogical intervention was made up of three moments: application of a diagnostic evaluation, instrument that enabled the creation of the teaching module by showing the level of the geometry knowledge of the students; introduction of a Teaching Module by Activities aiming to propose a reflexive didactic routing directed to the conceptual construction because we believed that such an approach would favor the consolidation of the learning process by becoming significant to the apprentice, and the accomplishment of a Final Evaluation through which we established a comparison of the results obtained before and after the teaching intervention. The data gathered were analyzed qualitatively by means of a study of understanding categories of mathematical concepts, in addition to using descriptive statistics under the quantitative aspect. Based on the theory of Richard Skemp, about categorization of mathematical knowledge, in the levels of Relational and Instrumental Understanding were achieved in contextual situations and varied proportions, thus enabling a contribution in the learning of the geometrical concepts studied along with the students who took part in the research. We believe that this work may contribute with reflections about the learning processes, a concern which remained during all the stages of the research, and also that the technical competence along with the knowledge about the constructivist theory will condition the implementation of a new dynamics to the teaching and learning processes. We hope that the present research work may add some contribution to the teaching practice in the context of the teaching of Mathematics for the intermediate levels of the Elementary School

Possibilidades de exploração da história da ciência na formação do professor de matemática: mobilizando saberes a partir da obra de Nicolau Copérnico de revolutionibus orbium coelestium

This study aims to analyze the implications that the knowledge of an important work for the History of Science, De revolutionibus orbium coelestium , by Nicholas Copernicus, can bring for the formation of Mathematics professors. The study focuses on Book I of Copernicus s work, where, in the final part, is found the Table of the Subtense Straight Lines in a Circle, a true sine table constructed by the author. The study considers two theoretical references, the History of Science and of Mathematics, in the professor s formation searched amongst others in Miguel and Miorm, Brito, Neves and Martins, and Radford, and the necessary teaching knowledge professors mst have, on the basis of Gauthier, Schulman and Imbernón amongst others, through which it is established a net of knowledge grouped in dimensions such as mathematical, psycho pedagogical, cultural and practical diversity, that guide the study analysis. In the search for more necessary elements to enrich the analysis, beyond the theoretical research in Book I, it is carried through, with under graduation pupils, future Math professors, the construction of a sine table following the project used in De revolutionibus . The study still makes a description of the life and work of Nicholas Copernicus, detaching the historical context where the author lived and the conceptions about the Universe existing at that time. The research reveals that the studied work is an important source of culture, able to provide to the Mathematics professor in formation, beyond the conceptual and procedural mathematical knowledge, a cultural knowledge that allows him to be opened to the knowledge of other areas that not his specific area, and so to acquire knowledge about the world history, the development of sciences and of the society

Círculo de ação-reflexão-ação: uma possibilidade praxiológica para a prática pedagógica da formação problematizadora de professores

Considering the dialogue as a gnosiological act and teachers as a researchers of their own practice, this thesis deals with the contribution of Paulo Freire thoughts to teacher s formation process. The study was made over an intervention carried out at a regular Pedagogy Course, however directed to teachers on duty inside a program called PROFOMAÇÃO (Special program for professional formation on Basic Education) promoted by Universidade do Estado do Rio Grande do Norte (UERN). From Freire s ideas of problematizing education, action and reflection dialectics, conscientization and from the analysis of the course itself, I support the idea that the dynamics of collective construction of knowledge- three pedagogical moments (ANGOTTI, DELIZOICOV e PERNAMBUCO) when intermediated by individual reflection, provided by written register, permits the development of three important dimensions of knowledge about pedagogical practice; observation and selfobservation; understanding the theories witch grounds the action; and theorization. By these means, initial and permanent teacher s formation could materialize its political commitment in a concrete action of collective and participative act of conscientization and transformation of the reality of pedagogical practice at school ground, developing itself as a truly circle of action and reflection

Como se fora brincadeira de roda: a ciranda da ludopoiese para uma educação musical humanescente

The present work concerns an auto-ethnographic study based on life experiences and reflections of an educator at Escola Viva Preschool and Elementary-Middle School, located in the city center of Natal, Rio Grande do Norte. As a cognitive model of operation, we use the metaphor of the Circle Dance. The objective of this study is to identify, interpret and describe the ludopoetics that are achieved through a Musical Education program, which we denominate, Humanescent. The data of this investigation was derived from the music making by Preschool and Elementary-Middle School students at Escola Viva during 2007, 2008 and 2009, from which 20 learners were selected to form the corpus, along with the description and interpretation of photos of their experiences and sand tray scenes. We justify the methodological systemization of the research based on our own pedagogical practice, which supports Musical Education in the schools based on the principals of Embodiment, Autopoesis and Flow. The methodological systemization was developed through an Action Research model and on the concepts of Systemic Development, with the goal of re-reading the context investigated through the structuring of categories of Ludopoesis: Self-esteem, Self-territory, Self-connectivity, Self-realization and Selfworth. We used an observant-participant research approach with regard to the perception of emergent knowledge, the surroundings, the experience lived and the contextual and vibration of the circumstances. Besides this, we used projection to interpret the experiences lived, in the form of drawings, short poems, letters or sand tray scenes as symbolic interpretations of experience. In the unfolding of the Ludopoetic Process (Selfesteem, Self-territory, Self-connectivity, Self-realization and Selfworth) we draw conclusions about the relevance of the ludic musical experience, which foments the formation of the self based on music learning, and which is demonstrated in the Embodiment of the learners. In the auto-formative process (of learners and educators) we observe the importance of pedagogical work based on Musical Humanescent Education that gives value to the music making path to the construction of music and performance in play, creativity, and sensibility. The experience of making music in a playful way allows for organization of the self and its autonomous production in the joy of living within a ludopoetic process. These findings highlight the educator as in a permanent state of selfformation, which generates moments of flow. However, in Musical Humanescent Education, music is learned collectively, doing a circle dance, experiencing love, fostering an expansion of the creative spirit, and giving recognition to playfulness as a necessary condition for education and to the value of music made with the true nature and sensibilities of the educators

Um estudo sobre a aprendizagem de alguns conceitos algébricos e geométricos

The objective of the present work was develop a study about the writing and the algebraic manipulation of symbolical expressions for perimeter and area of some convex polygons, approaching the properties of the operations and equality, extending to the obtaining of the formulas of length and area of the circle, this one starting on the formula of the perimeter and area of the regular hexagon. To do so, a module with teaching activities was elaborated based on constructive teaching. The study consisted of a methodological intervention, done by the researcher, and had as subjects students of the 8th grade of the State School Desembargador Floriano Cavalcanti, located on the city of Natal, Rio Grande do Norte. The methodological intervention was done in three stages: applying of a initial diagnostic evaluation, developing of the teaching module, and applying of the final evaluation based on the Mathematics teaching using Constructivist references. The data collected in the evaluations was presented as descriptive statistics. The results of the final diagnostic evaluation were analyzed in the qualitative point of view, using the criteria established by Richard Skemp s second theory about the comprehension of mathematical concepts. The general results about the data from the evaluations and the applying of the teaching module showed a qualitative difference in the learning of the students who participated of the intervention

As geometrias urbana e isoperimétrica: uma alternativa de uso em sala de aula

The main goal of the present study is to propose a methodological approach to the teaching of Geometry and, in particular, to the construction of the concepts of circle (circumference) and ellipse by 7th and 8th grade students. In order to aid the students in the construction of these concepts, we developed a module based on mathematical modeling, and both Urban Geometry (Taxicab Geometry) and Isoperimetric Geometry. Our analysis was based on Jean Piaget's Equilibrium Theory. Emphasizing the use of intuition based on accumulated past experiences, the students were encouraged to come up with a hypothesis, try it out, discuss it with their peers, and derive conclusions. Although the graphs of circles and ellipses assume different shapes in Urban and Isoperimetric Geometry than they do in the standard Euclidian Geometry, their definitions are identical regardless of the metric used. Thus, by comparing the graphs produced in the different metrics, the students were able to consolidate their understanding of these concepts. The intervention took place in a series of small group activities. At the end of the study, the 53 seventh grade and the 55 eighth grade students had a better understanding of the concepts of circle and ellipse

Slogans políticos em campanhas eleitorais no Rio Grande do Norte: a mídia na disputa ideológica.

To the observe the periods of electoral campaigns, we can realize sharply the abundance of political propaganda that announces the candidates, their campaign record, their proposed and everything that can carry them to the victory in the urns. The propaganda is today an essential tool in the votes dispute, in consequence of this, there is, in Brazil, the increasing participation of the Politics Parties in seminars of electoral marketing. They are varied strategies of the media used in the divulging of the candidacies, among them the slogan. Instigated by the explicit relation media/political, this work intends to investigate the ideologies (values) announced by the slogans of political propaganda that circulated in electoral periods. Thus, we base on the theory of the Circle of Bakhtin, who considers the statement as unit of the verbal communication, and that conceives the language as phenomenon dialogical, and, too, in the conceptions of alien words, social voices and dialogical relations formulated by the referred theory. We use, for better to comprehend, the slogan as strategy mediatic, of the classical study done by Olivier Reboul concerning the slogan; and, like starting point of a conception about ideology, studied John Thompson to comprehends the ideological phenomenon. Our corpus it constitutes of 14 political slogans announced in the campaigns for mayor of the cities in Natal and Mossoró, both located in Rio Grande do Norte s state, Brazil, in 1996, 2000 and 2004. For the analysis of these slogans, we consider the social-historical context in which were announced, being contemplated the linguistic and discursive aspect, according to the following methodological order: the identification of alien words (interdiscours); the social voices and the kinds dialogical relations established; and, finally, the ideology announced by the statement. This way, we can arrive to the conclusion that in the electoral context occurs a true ideologies war , in other words, in the political game of an electoral campaign, the slogans announces different values, which vary in several factors function, for example, the historicity, the subject that enunciates, the discursive positionings.

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

Um olhar dialógico sobre a atividade de revisão de textos escritos: entrelaçamento dizeres e fazeres

This research deals with the activity of text revision. It aims at understanding the work of the text reviewer, taking into consideration the professional experiences of the subjects who work in the area. It s theoretical basis comes from Bakhtin Circle, mainly the concept of verbal interaction formulated from reflections on language used in different spheres of human activities, which implies the notions of discourse genres, alterity, as well as exotopy. The methodology follows the tradition of the qualitative and interpretative research. The data is composed of the statements of text reviewers both in handbooks and interviews, as well as of the description of the researcher s own experience as text reviewer. The results indicate that the revision activity needs to be orientated by a dialogical conception of language, which takes into consideration the interaction between the reviewer and the author, aiming the text finalization
