This paper presents the results of a research about the higher education public policy, developed by Bahia State Government since 1961 until 2000, as part of a economic development project, on the first sight, but also essentially politic, which aim was: inserting Bahia State in the same process of economic development, in progress, in the states of southeast region and at the same time to enlarge the political power of the dominant elite, in the countryside of Bahia. It was chosen this specific period of time because of the guidelines and background for the national education under the Law 4.024/61 and the higher education reform under the law 5.540/68 whose promulgation date from 1960's decade. Those laws are contemporaries to the beginning of current complex of public state universities from the State of Bahia. The 1990 s represented for the political history of the State a landmark for the reorganization of the State and for the educational policy. It was a decade rich in debates about the new law, 9.394/96, its guidelines and background for the national education. The research was oriented by a main question that was formulated on the following terms: how the Brazilian historical conditions were reflected in Bahia and how it made the government of Bahia start the incorporation and spreading process for the higher education, compliant to the legislation but with contradictions, and at the same time, organizing the set of Universities from the state without losing the political control over those institutions? The general aim of the research was to analyze the public policies for the higher education, elaborated from the political reorganization of the Brazilian state mediated in politics of the State of Bahia, capturing from this process, the contradiction that involves the discussion about expansion / organization of the state universities and political centralization. The adopted methodology was supported by documental analysis revealing about the conception the liberal state, inside the political reform, and how the State conceives the matter related with the autonomy university. It was also carried out a bibliographic research in order to trace the trajectory of the conception of the autonomy existent in the national debate, inter-relating them with main aspects like economical, political and social that justifies that trajectory. That historical analysis also observed the relationship of those movements with the development process of higher education in national level, mediated by the specificities of ―Enigma Baiano‖. It is attested at the end of the considerations that the politics from the State of Bahia have strategies that favor the centralization process of administrative management and they also block any action of decentralization, which should be avoided even in its inception. In this context is also presented the contradictory relationship between the local power and the State Government highlighting the historical specificities of each period and region in question.

In Anti-Oedipus (1972), Deleuze and Guattari make original critical analyses of psychoanalysis, and offer theoretical and practical proposals for the problems they identify in the Freudian legacy. However, the aggressive written and the peculiar style of this venture do not attract the readers interested in psychoanalysis, and this polemical book is commonly confused with a project of destruction and overcoming of psychoanalysis. The result is that, so far, it is still not clear whether - or how - the conceptual formulation developed by these authors can offer contributions to the psychoanalytic field, and few is discussed about the importance and relevance of this critical proposal. The dialogue between this work and psychoanalysis is usually exempted, unless when you intend to reaffirm their opposition. It occurs that Anti-Oedipus maintains an ambiguous relationship with psychoanalysis, in that it does not cease to rely on central aspects of Freudian thought in its proposal to overcome the limitations and anachronisms of psychoanalysis. Indeed, the authors seek to devise an immanent and productive unconscious which is inconsistent with too expensive notions of psychoanalysis. On the other hand, the economic register of the Freudian unconscious is highly valued in this project, and the concepts of desiring-machine and body without organs, for example, are curiously articulated with the drives theory. Therefore, in this dissertation, we sought to present Anti-Oedipus considering that the authors also worked with the psychoanalysis, from a positive and specific resumption of the Freudian drives theory. Initially, we present this work through the concepts of desiring-machine and body without organs, advancing in their specific theses and identifying the assumptions involved in its construction. Then, we made some joints between these concepts and the Freud s drives theory, not suggesting that they are similar, but identifying the imposed questions to psychoanalysis from indications of Deleuze and Guattari. After this, it was found that these authors held a reading of the drives theory to compose the concepts of Anti-Oedipus, which is inseparable from a singular theoretical construction, where other problems and issues are being placed. We saw that his concept about the unconscious really goes beyond psychoanalysis, not because the beats, but because it is not limited to addressing psychoanalytical issues, much less is based only on freudian written to be forged. Thus, less than an iconoclast work, Anti-Oedipus emerges as a legitimate and vigorous enterprise in its investigation of the unconscious and the desire, where it is used to recommence alternatives lines witch born of psychoanalysis itself, through a complex preparation. The joints that we indicate and begin to explore here, are recognized as new possibilities of the reading of psychoanalysis, without, however, being reduced to this, but considered from its specific position.

On the first chapter, photosyntehsis network global connectance analysis (Cg) and principal components analysis (PCA) indicate, respectively, that decrease on net photosynthesis (PN) was accompanied by reduced autonomy in relation to environment and reduced variation of answers of all physiological network variables in clear day. High synchronization among physiological and meteorological parameters (reduced autonomy of cultivars in relation to environment) on clear day was considered the main cause of PN drop. This causal relationship was highlighted by results from PCA pointing out simultaneously: 1 - a clear contrast among physiological and meteorological vectors, 2 - reduced physiological variation of grafted and non-grafted individuals on clear day, and 3 - distribution of symbols representing clear and cloudy days close to meteorological and physiological vectors, respectively. Therefore, autonomy was strong parameter of stress condition of Coffea arabica on clear and cloudy days under field conditions in growing season. On the second chapter, young plants of C. arabica cultivars presented higher net carbon assimilation and quantum efficiency when treated for 14 hours at 17-23ºC (reduced temperatures) than when treated for 14 hours at 26-32ºC (elevated temperatures). At 17-23ºC, electron transport rate was not excessive, negative components of photosynthetic process are reduced, and biochemical and photochemical processes of photosynthesis are in equilibrium. The principal component analyses (PCA) showed that at reduced temperatures (17-23ºC) there was similar physiological behavior among cultivars. On the other hand, at elevated temperatures (26-32ºC), the cultivars displayed broader physiological variation and strong inhibition of photosynthesis at leaf temperature of 32ºC. On this extreme temperature it was brought about a decrease of carboxylation efficiency and an increase of mesophyll limitation of photosynthesis. Photosynthesis network of C. arabica was tightly adjusted at elevated temperatures (Cg values higher than at reduced temperatures). Network analysis and PCA in C. arabica were appropriate tools to discriminate the impact of stressing temperatures and the kind of responses of each cultivar under changing environment.

Studies have been identified both changes in the body and in the environment induce adjustments on the reaching, however few studies verified the influence of the size and rigidity of objects longitudinally in the period of 6 to 36 months, mainly employing the kinematic analysis and qualitative analysis of movements. Thus, two studies were conducted major (Studies 2 and 3) and a complementary study (Study 1). The aim of the Study 1 was to testing whether Dvideow system is a sensitive, objective and reliable instrument in the kinematic analysis of infant s reaching movement in the period of 4 to 6 months. Based on the positive results of this study has been the use of the system for analysis Dvideow kinematics of the reaching movement into Study 2. The aim of Study 2 was to verify the influence of the size and rigidity of the objects in the reach of children at 6, 7, 8 and 36 months. According to the results of this study are realized the importance of also qualitatively analyze the reaching movements, being carried out the Study 3. The aim of Study 3 was to analyze the influence of the size and rigidity of objects in proximal and distal adjustments of reach in the period of 6 to 36 months. Thus, nine healthy infants were positioned in a infant chair with 50° horizontal. Four objects were presented, a large rigid, a small rigid, a large and a small soft for a period of 1 minute each. The movements were filmed by three digital cameras. It was found that reaching from 6 to 36 months is characterized by changes both in cinematic and qualitative variables, which modify when necessary according to the most discrepance properties of the objects presented. It is suggested that this is a period of refinement of reach manual, in which the motor system continuous adjustments are made according to age (physical growth, improvement in postural control, differences in the perception of the objects in each age), the experience and environment, which in turn, can only promote changes in the parameters of the control needed to carry out the task

The current study is intended to investigate the conceptions of a group of Science (elementary) and Biology (high school) teachers who work in public schools (municipal and state) in the city of São Carlos about the Science, Technology and Society (STS) interactions. The relevance of this study lies on the fact that in the present world Science and Technology, with their developments and influences in the human, social, cultural and economical dimensions, have turned to be objects of debates regarding their potentialities, natures and limits, due to many factors, including their impacts on the well-being of society. So, it s considered that the understanding of the nature of science and STS interactions by both the teachers and the students is one of the essential aspects of the scientific literacy, indispensable to a critical and responsible evaluation of the scientific and technological policies. In this study, a qualitative approach has been used to interpret the data collected. The data was obtained by means of the application of, the VOSTS (Views on Science-Technology-Society) questionnaire to a group of elementary and high school Natural Science teachers. They were also submitted to a semi-structured interview with questions based on the VOSTS. The VOSTS questionnaire was applied in an abridged and adapted version. The answers of this version were categorized as realist, plausible and simplistic by Human, Natural and Exact Sciences researchers/professors. The results also show that the participating teachers of this study have some misconceptions about the STS interactions, including these ones: Technology is Science application; Science is a group of information; experiments and observations; Science is a technique for practical problem solving; Science is indefinable; every technological knowledge constitutes itself a single scientific discovery.

The prospect of submitting the concepts of ego and object to an investigation capable of detecting its conditions of possibility, its guiding principles and its methods, becomes an important tool for elucidating the Freudian analysis of subjectivity. Therefore, this dissertation aims at providing the necessary conceptual fundaments for a more critical and cohesive view of these concepts and analyzing the way we can find some ambiguities throughout its metapsychological construction. Regarding the concept of ego, we addressed its theoretical importance in initial construction of Freud s theory of defense, passing on to its partial ostracism and return , respectively in The interpretation of dreams and in the first papers on the theory of narcissism, and eventually to the topical reformulation which took place in The ego and the id, published in 1923, and the final Freud´s papers. In turn, the concept of object is central in the Freudian theory of sexuality, since Three essays on the theory of sexuality (1905), paper in which the concept of drive [Trieb] is introduced, and from whose fundaments all ulterior metapsychological developments set out. Considering the relations established with key-notions of metapsychology, and the critical presentation of the guiding elements from which one can apprehend the constitution of the concepts of ego and object in Freudian theory, we can conclude that both are important pillars that support the psychoanalytical knowledge and it is possible to examine relevant theoretical impasses in his metapsychology.

In this research, it was intended to show that Memories of Past and the Memories of Future, as created by Bakhtin, shared collectively by individuals in a social organization that produces self-images of those individuals in interaction. To defend that point of view, firstly it was necessary to define the original images of the individuals through their speech, and then to analyze how those memories have participated in that construction. First of all the corpus to analyze has been chosen: three books written by Italian immigrants that moved to Brazil when they were young and lived all their lives here. The construction of the images was considered like construction of identities. That process was studied as an otherness, i.e., identities are built from others. In the analysis, it was observed that the relationship between Memories of the Past and Memories of the Future, the latter project a future of peace, tranquility etc, and the former bring to present a past of pain, sorrow, poverty etc, created images of lawful individuals, workers, happy, persistent etc; and there was a direct relationship between those memories and those identities, i.e., one producing the other

The main aim of this paper is to describe and analyze the marriage alliance system of the Kalapalo, a karib-speaking group from Alto Xingu (MT), by means of a critical review of the available hypothesis on the xinguan kinship and the presentation of newer ethnographical data on alliance in relation to the presently available ones in the anthropological literature about the region. Such data allow to identify the types of existing unions and its respective statistical trends, subsidizing the test of the current hypotheses on the forms of transmission and production of affinity in upper-xinguan systems in the ethnographical context of the kalapalo system. Still, one becomes able to question about the real reach and also the limits of the hypothesis on the alliance structure of the peoples of the region to be of the (patri)multibilateral type, therefore the data disclose the existence of an ideal and a strong trend among the Kalapalo for the matrilateral marriage. Considering that the matrilateral exchange is not a common fact in indigenous Amazonia, where variations of the patrilateral marriage prevail, this characteristic of the kalapalo system leads us to question the multibilateral model considered for the upper-xinguan systems, and becomes a basic problem to investigate how these different structures combine in one same system. For that, a diachronical analysis of some alliance nets will be made, considering the conditions of production and redoubling of unions as well as the coexistence of two exchange structures (one patri and another matrilateral), what will lead to a definition of the kalapalo system as "complex" and to the association of the matrilateral marriages with the institution of chieftaincy.

This dissertation has the general objective of contributing to the theoretical and empirical comprehension of the implications of the internet for democracy and electoral processes. We analyze the cyberparadigms and the normative assumptions that influenced thematic production. The adopted analytical standpoint aims to apply the premises deriving from the theoretical apparatus of reference to a concrete empirical context, trying to balance the strong normative assumptions and overcome the notion of technological determinism present in much of the literature. This way, we delimit the way the internet is being used in electoral processes, its possibilities and limits, promoting an adaptation of expectations. We use a critical approach to be able to scrutinize the potential of the internet in reinvigorating democracy and its processes and exploring its actual conditions of production in specific political-electoral contexts, bringing elements of political culture to the center of the debate. For this analysis we used a systematic empirical base and a temporal specification: the Brazilian political-electoral context during the presidential race of 2006. The objects of investigation in a comparative perspective were the websites of the two main candidates for the Presidency of the Republic in the 2006 contest: Luiz Inácio Lula da Silva (PT) and Geraldo Alckmin (PSDB). Specifically, the empirical investigation was guided by the following research queries: 1) What are the functions and possibilities of interaction and participation in electoral websites? 2) Are there differences between the websites of the Alckmin and Lula campaigns in terms of sophistication and design that indicate different levels of professionalism? 3) What are the strategies of the cybercampaigns? 4) According to the options on offer, what is the main targeted public of the websites? This investigation began from four hypotheses: 1) the electoral websites will reflect more the function of top-down and one-way, neglecting the interactive possibilities of the new media in promoting dialogue with the electorate; 2) there will be convergence and standardization, instead of differentiation between parties, in the way of usage of the Brazilian political websites; 3) the online strategy will be centered more in attracting predisposed and politically active constituents, as well as grabbing the attention of media professionals, then apathetic and demobilized citizens, and finally 4) the Internet will be an important space for negative campaigning on part of Alckmin, due to his position of challenger in the contest and due to the political context that preceded the electoral race, highly scarred by accusations of corruption, as well as legal loopholes in relation to the internet. The reelection candidacy of President Lula will be centered in the publication of endorsements and in the retrospective strategy of incorporating symbols of the post of president and exploring actions of his first term in office. The methodological strategy adopted is based on the research design of Content Analysis of websites, applied on three levels of analysis: functional, formal, and content of the clippings and persuasive strategies of the candidates. These analytical dimensions are composed by indicators, typologies, and many categories that comprise diverse dichotomous variables.

This work aims to unveil the contradictions between the PSDB democratic discourse and the practice of its rulers before the educational reform promoted by this political party, especially in the state of São Paulo. In order to achieve that we read, analyzed and interpreted several documents by PSDB, which guide the political practices of its rulers both in the democratic and in the educational areas. We confronted all this information with the action of party rulers through the laws, decrees and resolutions issued during the terms of President Fernando Henrique Cardoso (FHC) and PSDB governors of the state of Sao Paulo, emphasizing Mário Covas s. Our field research was conducted in the city of Penápolis, which was directly affected by one of the measures adopted when the state educational system was reformed, that is, the closing down of he local board of education in April 1999. The city board of education is the link between local schools and the State Board of Education (SEE) and it was closed down due to restructuring done at the SEE. Due to the services offered by the local board, there was a strong reaction from the community, which put in motion a struggle for the reopening of the local board of education. It was actually reopened on June 29, 2006, now under a different name. Because of this struggle a unique fact happened in Penápolis: the election of the local board chairman instead of his indication by the state government. This was achieved after the formation of a Council composed of local and regional representatives from the town s administration as well as public school teachers. Nevertheless, we conclude that even though the facts that happened in Penápolis point to the possibility of a widening of democratic practices concerning powers of decision, this has not changed the governmental actions as a whole. The SEE still centralizes all decisions what shows the contradiction between PSDB s democratic discourse and governmental practices.

Human movement recording is a fundamental tool for studies that perform movement analysis which is very useful for Physiotherapy and Biomechanics. However, to obtain high quality movement analysis, reliable and accurate equipments are necessary. In this way, flexible electrogoniometers have shown high reproducibility besides other advantages as low financial cost, readiness of working and bilateral data recording. Nevertheless, these equipments are exposed to errors like: the equipment itself, data acquisition procedures and the crosstalk effect. Thus, two studies (Studies I and II) were carried through. The aim of study (I) was to assess knee movement symmetry on sagittal and frontal planes based on Maupas criterion, absolute symmetry index and on statistical analysis. Nine healthy subjects have taken part in the study. Knee movements were recorded by flexible electrogoniometers attached on both knees. The subjects passed by a familiarization period in the treadmill and, after this, the movements were recorded during 90 seconds at 5,0 Km/h. The recording was partitioned as strides and normalized in time using a routine developed in MatLab. Movement curves were derived from 50 strides. Maximum angle and range of movement were also calculated. Based on Maupas criterion, subjects knees were considered symmetrical for the flexion-extension and valgus-varus movements. However the frontal plane movements showed more variability than sagittal plane movements, what can be due to some crosstalk effect. The aim of study (II) was to evaluate the effect from eletrogoniometer sensors, procedures (consecutive trials) and the knees during gait recordings. Knee flexion-extension and valgus-varus movements were recorded during treadmill walking. The recording was partitioned as strides and normalized in time using a routine developed in MatLab. Curves were derived from 50 strides, and seven conditions were evaluated: one for comparing two sensors; two for comparing two different trials (including variation due to sensor); and four for comparing right and left knee (including variation due to sensors and trials). Mean standard deviations of the differences were calculated. To estimate the variations due to trial and knee, the compound SDs were transformed into variances and split into its components. Differences between normal knees had more influence in determining variation on the results than sensors and trials for most of the subjects. Variation was much higher between knees for valgus-varus than for flexion-extension movements. Individual sensors showed the smaller source of variation. Thus, it is preferable to use different sensors in the same data recording (simultaneous) than use the same sensor in two different recordings (consecutive).

This research is part of a study on long term educational processes aimed at the training in environmental education. The investigation focused on the specialization course Education of Local Socio-environmental Sustainability Agents , offered by the University of São Paulo in 2003, with the objective of preparing university employees for environmental educational actions in their workplaces. The study analyzed the impact of the course on the employee s workplaces, according to the participants themselves, as well as the difficulties and conflicts experienced by the participants in their educational activities. The study also examined the conceptions of the environmental educator s role and tried to identify the elements, as perceived by the participants, that favored their preparation as environmental educators. Five participants were interviewed and another 18 answered a questionnaire. As complementary sources of information, class plans, written reports and evaluations and meeting records were used. The results of the study include the identification of the actions promoted by the employees in their workplaces, involving both educational and environmental management activities. The praxis, the creation of a learning community and the use of autobiographical reports were positive elements in the development of the employees as environmental educators. The main challenge faced by the local agents is to understand and to deal with political aspects of the institution and with the lack of a global environmental policy for the university.

In this work, nickel electrodeposition has been studied in the presence of the additives BTAH and/or EDTA onto platinum substrate from Watts plating bath, at different pH. The deposition and dissolution processes with or without additives were investigated through voltammetric techniques. The deposits obtained from these electrolytic solutions were analyzed by scanning electronic microscopy (SEM), X-ray dispersion (EDX) and X-ray diffraction (DRX). Voltammetric studies showed the presence of additives in the plating bath the deposition current densities decreased. The anodic scan suggested the formation of different nickel crystallographic faces, besides that it also suggested other processes that can occur in parallel with dissolution of deposits. The highest efficiencies of the deposition process were obtained at low jdep for all systems studied. The hydrogen evolution reaction occurs simultaneously to the nickel deposition process since the initial moments. The nickel deposition studies from alkaline solutions that contain high concentration of EDTA showed that the complex NiY2- did not discharge to metallic nickel. The deposits were formed only when EDTA was used in low concentrations (additive proportions). Analysis of the deposits by SEM showed that the best conditions to obtain these deposits were carried out at Ed = -1,0 V or jdep = 2,5 mA cm-2 from nickel solutions at pH 6,0 in the presence of 1,0 x 10-3 mol L-1 BTAH. By EDX analysis we could verify that there was O and Cl incorporation in the deposits. The deposits of nickel morphology depends on the deposition potential and consequently on chemical composition of the deposits.

The gill structure of the Amazon fish Arapaima gigas, an obligatory air breather, was analyzed during its transition to obligatory air breathing behavior and the obtained data was related to its breathing mode. Gills of fish weighing between 2 to 5000g were collected, fixed and processed for morphometric analysis, histochemistry, imunohistochemistry, transmission (TEM) and scanning (SEM) electron microscopy (chloride cell fractional area, CCFA and density). In the first stages of development the gill filaments is as those of water-breathers, but there s intense changes while the animal grow, with influence on respiratory function and ionic exchanges. The lamellae keeps its organizational structure, including red cells passing through it, but them become to vestigial in fish since 1000g, being the interlamellar regions filled with filament cells. The most important cell types of the gill epithelia are the chloride cells (CCs), mucous cells (MCs) and the pavement cells (PCs). The PCs shows irregular shape and random microridges on the cell surface. Two cell processes are involved to gill changes, cells proliferation and programmed death cells (apoptosis); there is an intense proliferating cells until animals reach 500-600g. Apoptotics cells were low in all the animals observed. The number of CCs are low in animals under 100-200g and increased in the filament and lamellar epithelia in animals up to 1000g as well as the CCFA. Two kinds of MCs were observed, PAS positive and Alcian Blue positive. There was a significant raise in both cells until animals with 100-200g and PAS positives until 500-600g. These cells seem to play an important role relation with ion regulation. The transition to air breathing and the restriction for aquatic respiration result in gill changes in A. gigas, and the gills may play other important functions like ion and acid-base regulation, optimized by its epithelia cell kinds and its design.

Children with hearing impairments which study into the regular school can be isolated andrejected by their peer group and can exhibit more learning disability, emotional andbehavior problems than children that don't have deficiencies. Theoretical field of socialskills has been dedicated to the study of these questions. However the literature don tindicate which performances from the children could contribute or hinder the inclusion ofchildren with hearing impairments on their interpersonal relations, just as there a few dataon the relations between these performances and the social isolation and rejection by thepeer group, academic competence and behavior problems. This work was divided into tworesearches. The purpose of the research I consists in identify the inclusive social skills,by categorizing the pro-included performances and from the anti-included performances.Participated in this research I eight children with hearing impairments and 128 childrenwithout deficiency of eight classes of 1ª the 4ª grades of regular schools. By means offilming from the classes in the classroom and classes of the physical education, have beenidentified and categorized 30 pro-included performances and 20 anti-includedperformances from the children. The objective of the research II was observe the relationamong the pro-included performances and the anti-included performances and: a) the socialskills; b) the behavior problems; c) the academic competence; d) the sociometric statusfrom the children. Participated in this research II eight children with hearing impairmentsand eight children without deficiency of eight classes of 1ª the 4ª grades of regular schools.The statistically descriptive analysis suggested the relation among these performances andthe repertory of social skills and the academic competence from the children. The datarelative to the behavior problems and the sociometric status from the children don t suggestthe relation among these variables and the pro-inclusive performances and anti-inclusiveperformances.

The curricular reformulation process which is established for every graduation course at National institutions of Higher Education, has the instructions for these curricular modifications in the National Curriculum Guideline CP01 and CP02 of 2002. Considering the course of Physical Education at UEL as a reference, we can realize that the curricular project of this course was installed in 2005 and it treats specifically the Physical Education teacher s education Licentiate degree. Recognizing the importance of the initial formation's task at teachers' professionalization and knowing that the possible changes in school institutions depend on this initial formation, this inquiry intend to analyze how teachers of the Physical Education course have translated the principles and guidelines which direct this curricular project into pedagogic practice. The main issue in this inquiry is teachers educators, because when they propose and resolve changes in the teachers' formation, they are also involved in a learning process and professional development. The specific elaborated goals were the following: a) Identify and analyze boundaries, challenges and difficulties found by teachers during the curricular project establishment; b) Describe and analyze teachers' initial learning derived from the curricular project establishment based on the perspective of the participant teachers; c) Identify, based on the narrative of the interviewee, that knowledge is recognized as important for the Physical Education teachers' education. We voted for a narrative inquisition in the current study, because it is understood that it characterizes the human experience phenomenon which is built during personal and professional life. A Semi-structured Interview was taken as a source for the data collection. This Interview was made with a teacher group that took part in the first year-Licensure establishment UEL (2005). Also, a Thematic Analysis was taken to treat and analyze the collected data. The results have showed the necessity for an association between school institution and university as one of the possibilities of teachers' professional development. The initial formation must approach the educative practice into school and must become an investigation field in a process of collaboration among different professionals.

The development of a performance measurement system raises challenges related to both its role of application, involving the decision makers, and its range over the organization processes. Some processes are not yet properly incorporated in the literature on performance measurement systems, at least not in a structured and well articulate way, being usually represented only by a group of performance indicators. One of these processes is the Product Development Process (PDP)whose relevance given both by the academy and by the corporations justifies an investigation on how a performance measurement system should be developed to facilitate the appropriate use in search of speed and efficiency in new product development. Within this context, this thesis deals with two major subjects within Production Engineering simultaneously approached: a model for developing performance measurement systems to support product development process management. Such model has also the intent of highlighting the constraints and restrictions involved in performance systems structure and implementation. For this purpose a literature review was carried out. It has pointed out a gap in dealing with these two subjects simultaneously in Production Engineering field. A model was built considering the literature review on the subjects and also empiric evidences collected from four companies in several business segments. A multiple case study took into account the prospective of using performance measurement in different hierarchical levels. Furthermore, during the visits to the mentioned companies, important aspects were revealed regarding to the development of the performance measures and the articulation among these measures. Aspects as organizational structure, business model and competitive scenery, PDP management framework and information technology, all influence and impact the performance measurement systems development. However, in the studied companies, very few performance indicators were found, different from the traditional "cost, time and quality .

In this work, the use of ethylene-vinyl acetate copolymer (EVA) in substitution to compatibility agents normally employed in the production of high density polyethylene (HDPE) nanocomposites (such as polyethylene grafted with maleic anhydride - PEMA) was evaluated due to its intrinsic polarity and relative low cost. Two EVAs with different melt flow indexes and vinyl acetate contents and two organophilic clays treated with different organic surfactants were used. It was verified that EVA with lower viscosity and higher polarity showed better interactions with the clay treated organically with polar surfactant. However, these characteristics reduced the HDPE/EVA compatibility. HDPE/EVA/MMT nanocomposites were obtained through melt mixing and subsequently blown as films. An Intercalated nanocomposite (HDPE/EVA 8/C15A) and a nanocomposite characterized by the presence of tactoids of the organoclay (HDPE/EVA 25/C30B) were produced. From rheological, morphological and permeation analysis it was found that the addition of clay modified the interfacial interactions between HDPE and EVA, increasing the system compatibility when compared to the HDPE/EVA blends behavior. Comparing with the HDPE/EVA blends, the better compatibility in nanocomposites were followed by an increase in elastic modulus, yielding and rupture behaviors and permeability properties. But these properties did not increase when compared with the pure HDPE film. The best results were obtained with the HDPE/EVA 8/C15A nanocomposite.
