(Universidade Federal de São Carlos, 2013-12-11) Almeida, João Flávio de; Romão, Lucília Maria Sousa; https://lattes.cnpq.br/8828821460772801; https://lattes.cnpq.br/4157503916940767
This work aims to analyze the media statements about the "new": analyzing the discourse that older objects and knowledge that are not yet unusable. To do so, we will try to tread a path through the theoretical issue of consumption (before becoming consumerism), trying to analyze historically the conversion process of enduring relationships (with objects, people, knowledge etc.) in ephemeral relationships, from discourse of obsolescence. Once defined and analyzed the theoretical framework, we will analyze three discursive materiality (in order: the movie "The Last Laugh", the advertising campaign "Intel Ultrabook Convertible", and the movie "The Devil Wears Prada") with the intention of analyzing the discourse about the "new" and obsolescence.

In the activity of supplying sugar cane to the mills in Brazil, there are governance structures differentiated between plants and also for the same plant. These structures range from the highest level of hierarchy vertical integration, in which the plant produces its own fields in the raw material for its supply to the less of hierarchy spot market, in which the plant gets the sugar cane from outside farmers without contracts or commitments with the following crops. Between these two extreme governance structures have been identified other supply arrangements called hybrids. The main objective of this thesis is to identify the factors that influence the choice of governance structures present in the supply of sugar cane in a given group of mills in the West region of São Paulo/BR State. The specific objectives are to: a) show what determines the representativeness of each governance structure in the mills selected in the West region of the state of São Paulo; b) identify the existence of plural forms; c) analyze the factors that justify the option in the mills for plural or singular forms of governance in the same type of transaction in the region West of the state of São Paulo; and d) compare the supply strategies of the plants of western São Paulo. This analysis was performed under the focus of the New Institutional Economics literature, especially dealing with the characteristics of transactions Transaction Cost Economics. The research is characterized, as the social group as explanatory research. To this end, it was applied an interview to the decision makers for supplying of raw material in the mills that represent a group of ten unities located in the west of São Paulo by competing for suppliers and land . It was observed that the characteristics of the transactions locational and temporal specificity, uncertainty and frequency are not determinative for the choice of governance structures, as recommended by the literature of transaction costs. These same characteristics make plants adopt formal mechanisms, provided for in contracts, and informal control transactions. The characteristics of transactions in supply of sugarcane exclude one of the governance structures observed in the literature the spot market but do not determine the uniqueness of others. The results also indicate that the plurality of transactions that serve the same purpose is common in the units studied and is related to the history of these plants, the need to eliminate some uncertainty in the supply and the balance between risks and disadvantages of singular forms. The singular forms, observed in only one case, appeared only as a function of need for financial restructuring of the company. Finally, it was noted that there is a significant diversity of arrangements for the supply of sugarcane in western São Paulo, hampering the framework of the structures observed in this research that was presented in the literature so far.
Contribuição das práticas educativas para o ensino da matemática nos anos iniciais: análise de uma experiência disciplinar colaborativa
(Universidade Federal de São Carlos, 2013-12-11) Graupner, Marli de Carvalho; Nakayama, Bárbara Cristina Moreira Sicardi; https://lattes.cnpq.br/9746628149674449; https://lattes.cnpq.br/0106429535599187; Gama, Renata Prenstteter; http://lattes.cnpq.br/4153572041829838; Lorenzato, Sergio Apparecido; http://lattes.cnpq.br/0433106167291528; Passos, Laurizete Ferragut; http://lattes.cnpq.br/1852839499967790
The present research aims to identify the contributions of the discipline Methodology and Practice of Mathematics Teaching on the Training of teachers who teaches mathematics in the early years of Elementary School. The research was developed in the Post Graduation in Education at Universidade Federal de São Carlos (UFSCar), Campus Sorocaba, connected to the search line "Teacher Training and Educational Practices" and integrates discussions from Project Education Observatory OBEDUC 2012. In terms of theoretical reference for addressing the models of teacher training were used the studies of CURI (2004), GATTI (2010), CURI & PIRES (2008), FOERSTE (2005), FIORENTINI (1995) e COCHRAN & LYTLE (1999). It is structured from an analysis qualitative and interpretative from the catalog and the teaching plan, as part of the material produced by the protagonists students of the discipline Methodology and Practice of Teaching Mathematics, offered on the period 8th Pedagogy course at UFSCar Campus Sorocaba, besides the script of classes held. To substantiate the analysis were used theoretical references that deal with the conceptual and didactic aspects to the teaching of mathematics. In that perspective were considered the contributions of the studies of NUNES (2005); SMOLE (2001); TOLEDO & TOLEDO (1997); FREITAS (2001), TANCREDI (2012), LORENZATO (1995) e FIORENTINI & LORENZATO (2006). The results given point that the conduction of the discipline in the colaborative perspective, presented some alternatives for concrete changes of the practice and opened possibilities for new meaning in vocational training, regarding the teaching of mathematics. The articulation between dialog, negotiation, mutuality and trust ran through all the classes and thereby it was possible to reach the goals initially proposed by the discipline in a positive and enriching way.

(Universidade Federal de São Carlos, 2013-12-11) Coelho, Marcio; Hayashi, Maria Cristina Piumbato Innocentini; https://lattes.cnpq.br/7428325329672198
The central theme of this research consists on the theoretical foundation research in Education. The overall objective was to realize a bibliometric and epistemological analysis of the doctoral theses of the Post-Graduate Program in Education UFSCar, to determine the epistemological paradigm that predominated in such research and thus explain the relationship between the production of scientific PPGE-UFSCar and the changes that occurred in the socio-historical context and also in research on education in Brazil from the 1990s. The empirical research that has limited the scientific production of the PPGE Doctoral Course in Area of Concentration in Foundations of Education, the theses defended in the period between 1993 and 2007, totaling 55 theses. As the theoretical framework, although this work presents the different epistemological paradigms that underlie research in Education, was designed specifically for Dialectical Historical Materialism. Regarding methodology, this research is exploratory and descriptive, it was dedicated to identify and analyze the scientific production selected. For this end, we employed the following techniques: a) bibliometric analysis to treat and analyze quantitatively the scientific consist of the 55 theses; b) content analysis to determine the theoretical and methodological framework that guided the research techniques as well as epistemological, ontological and ethical present in the process of knowledge production; c) analysis of questionnaires completed by faculty advisors, and its main publications, expanding the discussion on the theoretical present in the production of scientific PPGE. Sources of research data were: a) the theses obtained in Community Library UFSCar and file PPGE-UFSCar as well as the Digital Library of Theses and Dissertations of BCo/UFSCar; b) the Bank of Theses and Terms Indicators of the CAPES, which provided information about thesis bibliometric; c) the curricula of Plataforma Lattes of doctoral students and faculty mentors; d) questionnaires answered by faculty advisors and their major publications. The search result is provided in three parts, the first being a historical overview of educational research in Brazil, located in the educational context and broader social, then notes on the philosophical foundations of the major paradigms used in educational research, and finally the third part presents the elements of analysis of scientific production, the object of the research context, and the procedures and results of analysis of doctoral theses. Results reveal the dominance of the paradigm of Historical Materialism Dialectic, used in over 63 % of the theses, followed by post-modern trends, used in 30 % of searches, and Phenomenology, used in three theses. No thesis used Positivism as epistemological paradigm. These ratings were corroborated by the epistemological, ontological and ethical assumptions, as well as by references to authors and works connected to these paradigms.
O referencial teórico de Paulo Freire no ensino de ciências e na educação CTS: um estudo bibliométrico e epistemológico

The Science Teaching, spurred by the development of science and technology as well as the field of education, seeks paradigms that go beyond positivist approaches and linear knowledge production. Perceptions of the social dimensions of science and technology have led to this PhD study to realize a proposal within the dialogic Science Teaching and STS Education (Science, Technology and Society). Perceptions of the social dimensions of science and technology have led to this PhD study to realize a proposal within the dialogic Science Teaching and STS Education. The aim of this study is to verify the ownership of the theoretical framework of Paulo Freire in Science Teaching and Education CTS, represented by the scientific production of theses and dissertations and courses offered by the graduate. Represented by the research questions: How do I set the presence of referential Freire in STS Education and Teaching STS represented by the scientific production of theses and dissertations and the disciplines offered in graduate? What are the epistemological bases underpinning the theses in the field of Education and Higher Education STS adopted the theoretical Freire? The methodological procedures used include bibliometric research and epistemological analysis, with the construction of four matrices analysis, which reach the theoretical, epistemological, ontological and gnosiological of the studies analyzed. In bibliometric survey data collection was made on Bank CAPES thesis and Notebook Indicators Capes. To search for theses and dissertations search terms used were combinations of "STS Education" "Teaching STS" and "Science Education Paulo Freire. The data were processed in VantagePoint software and Excel ®. We analyzed 43 studies that used the theoretical perspective of Paulo Freire, 34 masters and nine doctoral. In Notebooks Indicators Capes data were collected from 57 subjects of 22 educational institutions in search of references related to Paulo Freire. Bibliometric analysis results indicate that the theses and dissertations are concentrated in the area of Education and Science and Mathematics at the Federal University of Santa Catarina, Universidade de Brasília and São Paulo University. To relate data from the Bank of Theses and Notebooks Indicators analyzed data from UFSC, UNB and USP with the literature of the subjects of their graduate programs, identifying literature Paulo Freire used: Pedagogy of the Oppressed and Pedagogy Autonomy. The epistemological analysis was performed by analysis of three matrices: 1) matrix ownership Freire's theoretical framework, 2) matrix paradigmatic STS , and 3) analysis matrix epistemological framework Freire. Results of the research show that the epistemological bases underpinning the theses in the field of STS Education and Science Education adopted the theoretical Freire point to changes that include critical-dialectical approaches. Work on Science Education seeks to revise the linear and positivist paradigm to which they are subjected. And work in STS Education /Science Teaching clarifies their limitations and seeks complementarity with the pedagogical thinking of Paulo Freire. Built in a humanistic and critical, the subject of knowledge is central, built and socio-historically mediated world. This study aims to add knowledge to the studies Freirean of Science Teaching and STS Education, in the sense that their results contribute to the expansion of critical mass on the need for theoretical research in Science Teaching in STS perspective.
Desenvolvimento de sistema para obtenção de filmes finos supercondutores de alta temperatura crítica (HTS) por deposição por laser pulsado (PLD)
(Universidade Federal de São Carlos, 2013-12-11) Cichetto Júnior, Leonélio; Moreira, Fernando Manuel Araújo; https://lattes.cnpq.br/1809254923092721; https://lattes.cnpq.br/7434408308350513
In this PhD work, the building of a PLD (Pulse Laser Deposition) system was accomplished with resources provided by FAPESP / CEPID / CMDMC, for the purpose of depositing thin films using an 248 nm pulsed excimer laser as external power source. The project presented here demonstrates that this work has the distinction of being a pioneer in Brazil in which says respect to superconducting thin film deposition trough PLD technique. Deposition of YBCO (YBa2Cu3O7-δ) thin films was the process chosen by us to calibrate and test the assembled system, as well as to learn the details of superconducting thin films deposition. The context of this work consists in a historical introduction to the laser deposition technique, comparison of techniques for thin film deposition trough physical methods and a brief review of the superconductivity theory and the theory of thin film growth. In the experimental part, we describe the assembly of the PLD system in detail, as well as we describe the analysis of the principal parameters that say respect to the technique and the fabrication of the targets utilized in the deposition. Finally, we describe the results of the characterization techniques applied to the study of thin films deposited by PLD. X ray diffraction(XRD), scanning electron microscopy (SEM) and DC magnetic susceptibility measurements were used to analyze the superconducting thin films. Due to it pioneer condition, this work enables the Group of Materials and Devices (GMD - DF / UFSCar) as well as the CMDMC to engage in new research, not only in superconducting materials, but also in the fabrication of devices based on thin films, such as sensors, multi-components heterostructures, RAM memories, electrodes, polymers, biocompatible thin films, the GMR effect, graphene, among others, that can be fabricated precisely and controllably by the PLD technique.
