The present study has proposed a structural model to identify the reasons why individuals become voluntary, keep and exit this type of work. The empirical space was the Pastoral da Criança - social action agency of the National Conference of Bishops of Brazil (CNBB) - community-based institution that has its work based on solidarity and the sharing of knowledge. The theoretical framework has the context in which are volunteering studies in Brazilian and world level. Then discuss the various concepts of volunteering and presented the theoretical models of volunteer motivation. Studies of Mostyn (1983) and studies conducted by the BEPEGE-Base for Studies and Research in Management Policies and Strategies - in their line of research GERQUAL - Human Resource Management and Organizational Quality - of the Federal University of Rio Grande do Norte as Carvalho e Souza(2006), Souza, Medeiros e Fernandes (2006), Souza et al (2009, 2010), Cavalcante et al (2011a, 2011b, 2011c, 2011d) were the main theoretical references for the construction of the model that was tested. Data collection was done through a survey with 71 indicators, in 2 visits to cities from the Diocese of Pesqueira, Pernambuco. The first data collection occurred in the period between May 30 and June 3, 2011, in Buique/PE and the second collection happened in Pesqueira/PE, in St. Joseph Seminary, in the period between July 6-8, 2011. 720 questionnaires were collected. The sample was divided into two parts. Exploratory Factor Analysis was applied in first part and Confirmatory Factor Analysis - structural equation modeling - in the second half. The examination of the results achieved by the expectations, reasons for entry, reasons for staying and exit reasons showed that all hypotheses were accepted. So the motivation of voluntary Pastoral da Criança can be explained by a set of interactions between these five constructs: Altruistic, Affectionate, Amiable, Adjusted and Astute

The discussions concerning the absence of a management model appropriate to the peculiarities of third sector organizations have not been impeditive to their emphasized expansion in the last decades. In the attempt of understanding this phenomenon from the perspective of those who manage social organizations, this work based on the theory of social representations to understand the notion that organization managers of the third sector - based in Fortaleza CE - have of the part that they play and how this notion influences the direction of their activities. Social representations of managers of four different categories of non-governmental organizations have been investigated, each category composed of two unities. The categories researched were: social integration through art and education, prevention and treatment of alcohol and drug abuse, children s health assistance and community action. By using Doise s Societal Approach, the role of social managers translated in intraindividual, interindividual and situational processes of their actions, has been analysed within the social representations, focusing on beliefs, values, symbols and stories that give meaning to the existence of non-governmental organizations. Analysis and discussion of data displayed the existence of diversity in the understanding of managers within their practice, in other words, the management profile is also its own manager s. The branch where an organization acts is also preponderant in the shaping of a management style. It could be deduced, from to the organizations researched, that professional formation and the manager s social insertion mainly, are determinative factors in the outlining of a management model of its own. It was concluded that, due to heterogeneity of interests and action segments, there is no systematic process for social management among organizations. Management styles are supported by their director s own perception of achievement, who model organizations according to their contingencies

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

The cobalt-chromium alloy is extensively used in the Odontology for the confection of metallic scaffolding in partial removable denture. During the last few years, it has been reported an increasing number of premature imperfections, with a few months of prosthesis use. The manufacture of these components is made in prosthetic laboratories and normally involves recasting, using parts of casting alloy and parts of virgin alloy. Therefore, the objective of the present study was to analyze the mechanical properties of a commercial cobalt-chromium alloy of odontological use after successive recasting, searching information to guide the dental prosthesis laboratories in the correct manipulation of the cobalt-chromium alloy in the process of casting and the possible limits of recasting in the mechanical properties of this material. Seven sample groups were confectioned, each one containing five test bodies, divided in the following way: G1: casting only with virgin alloy; G2: casting with 50% of the alloy of the G1 + 50% of virgin alloy; G3: casting with 50% of the alloy of the G2 + 50% of virgin alloy; G4: casting with 50% of the alloy of the G3 + 50% of virgin alloy; G5: 50% of alloy of the G4 + 50% of virgin alloy; G6: 50% of alloy of the G5 + 50% of virgin alloy and finally the G7, only with recasting alloy. The modifications in the mechanical behavior of the alloy were evaluated. Moreover, it was carried the micro structural characterization of the material by optic and electronic scanning microscopy, and X ray diffraction.and fluorescence looking into the correlatation of the mechanical alterations with structural modifications of the material caused by successive recasting process. Generally the results showed alterations in the fracture energy of the alloy after successive recasting, resulting mainly of the increasing presence of pores and large voids, characteristic of the casting material. Thus, the interpretation of the results showed that the material did not reveal significant differences with respect to the tensile strength or elastic limit, as a function of successive recasting. The elastic modulus increased from the third recasting cycle on, indicating that the material can be recast only twice. The fracture energy of the material decreased, as the number of recasting cycles increased. With respect to the microhardness, the statistical analyses showedno significant differences. Electronic scanning microscopy revealed the presence of imperfections and defects, resulting of the recasting process. X ray diffraction and fluorescence did not show alterations in the composition of the alloy or the formation of crystalline phases between the analyzed groups. The optical micrographs showed an increasing number of voids and porosity as the material was recast. Therefore, the general conclusion of this study is that the successive recasting of of Co-Cr alloys affects the mechanical properties of the material, consequently leading to the failure of the prosthetic work. Based on the results, the best recommendadition is that the use of the material should be limited to two recasting cycles

The paper investigates the legal mechanisms used by the Legislature and the Executive to implement the constitutional principle of the teacher s minimum wage, which is proclaimed in the Constitution as a strategy of professional appreciation for this category. The text demonstrates that the legal mechanisms used to value the teacher were: the 1988 Constitution, the constitutional amendments to this Charter updated and modified the original text in relation to the matter, and finally, the Minimum Wage Law . Article nº 206 of 1988 s Federal Constitution established that basic education teachers, who work in public schools, would be entitled to a national minimum wage. Law nº 11.738/2008 ( Minimum Wage Law ) regulated the matter and made other determinations on the relationship between the State and the teachers such as the establishment of parameters for the distribution of the workload of teachers. Based on this law, since 2009 the minimum wage has been set annually by the Federal Government. However, state governments and municipalities throughout Brazil protested prescriptions contained in the Minimum Wage Law . In this context, some governors and mayors led the Supreme Court regarding the constitutionality of this law. The complainants considered that there was unconstitutional by the following: definition of the teacher s workday, which in the complainants point of view was competence of local governments; ensuring that teachers receive salaries tied to the minimum wage with retroactive effect; transformation of the minimum wage in basic salary, lack of sufficient budget in the states and municipalities to honor with the new values to be paid to teachers and, finally, determining workload for the teacher to perform other activities besides classroom activities. At the trial held at the STF the majority of Ministers rejected the claim and considered that the Minimum Wage Law , taken together, was constitutional. However, this decision did not alter the position of the managers or the interpretation of the ministers who agreed with the unconstitutionality of some aspects of the law. This means that one law can present differences in interpretation between ordinary people and among members of the Judiciary. The search showed the following conclusions: the law is not a definitive parameter of justice, because it is deeply linked to various interests; the development, implementation, and judgment of laws dealing with minimum wage of teaching are linked to historical and cultural aspects of society; the demand for enhancement of teacher and setting a minimum wage has only emerged in the late twentieth century, a fact explained in this work based on data that indicate the recent concern of Brazilian State with schooling a phenomenon typically Republican and with the professionalization of teaching emerging concern from the knowledge society; the Legislative and Executive search mechanism to implement the minimum wage of the teachers because of the contemporary need for professionalization of teaching

The Thesis weaved in the (auto) biographical boarding studies the existence of existential teaching, in the scope of Superior Teaching, guided in the experience and the (auto) formative scope as a theoreticianmethodological support present in the classrooms, being three the essential questions: Which the way of (auto) formation traveled by professors of Superior Teaching, what is, for these citizens, the teaching in Superior Teaching and what they understand from existential teaching according to their narratives. The epistemology of this work, based on Program of After-Graduation in Education of Universidade Federal do Rio Grande do Norte, Support of Research: Professionalization and Formation Lecturing emerges, especially, of the studies and research realized by Ramalho and Nuñez (2005, 2006), Morosini (2001), Pimenta and Anastasiou (2002), Nóvoa (2000), Josso (2004), Dominicé (1988), Catani (2002), and Souza (2004), among other authors, yonder the educational practice exercised by researcher and involved citizens in inquiryformation, what it is confirmed from the three methodological tools that given support to the covered way: Eight topic narratives, a participantcomment and seven laboratories or parallel meeting of formation (EPF's) experimented with licensed teachers that actuate in superior teaching institutions (IES), public and private, localized in the city of Natal/RN. The Thesis points out, in this way, existential education in the guideline of viable and concrete methodological alternatives amongst the problematic of the (auto) formation faced for the professors in Superior Teaching

The present work, based on the methodological principles of the Comprehensive Discourse Analysis, aimed, through the speech of twelve newly arrived students at the Pedagogy course of the Federal University of Rio Grande do Norte, to understand the moment students start university. It also aimed to analyze the relationship between the schools they were coming from and university entrance as well as the relationship between university and their new students. In the first part of the work, which focused on school knowledge, a comprehensive listening of the speeches of the students led primarily to a distinction, established by the students, between public and private schools, a distinction especially based on the view of superiority of private schools against public ones. The abovementioned interpretation is found in the discussion of the structural duality of Brazilian education which, historically, offers different pedagogical appliances among students of more priviledged social classes and those who come from lower levels of society. The overcome of this duality, aspired by the Brazilian Constitution of 1988, was stopped by the advent of a new economic model neoliberalism, which reinforced the differences between public and private when it prioritized the market on the economic, political and social relations, including educational projects. Impoverishment of public institutions and pauperization of the work of professors affected also the relationship between teachers and studens at the current institution. This is how the teacher becomes the greatest villain at the public management system. All of these references concerning differences in the quality of teaching at public and private schools, expressed by the students interviewed, however, were centered in the preparation for the entrance exam, called vestibular, thus showing a view that the relationship between the student and the school he came from is of a propedeutic kind and even so, reduced to a preparation for an entrance exam. In the second part of the work, which analyzed the relationship between newly arrived students and their university, it was noticed that the latter represents a whole new world. This world is seen as the change at the student´s social statute for now he is grown, takes more responsibilities and is socially respected. This change of attitude established by society and the discovery of a new world which requires more independence from the students, creates in them feelings of pride and fear and they feel insecure when it comes to making decision in the campus because now their decisions deliver a greater load of responsibility. This is when students understand they need to develop autonomy, which is seen, in this work, as the capacity to make conscious decisions. Nevertheless students expressed an understanding of autonomy as something that comes as a gift for those who enter university and not as a process that is constructed from social experiences. For these students, the need to be autonomous refers to the relationships with their teachers and the search for information. This search, however, is also related, according to interviews, to public school financial cuts, which penalize university, and to the lack of employers

The knowledge management has received major attention from product designers because many of the activities within this process have to be creative and, therefore, they depend basically on the knowledge of the people who are involved in the process. Moreover, Product Development Process (PDP) is one of the activities in which knowledge management manifests in the most critical form once it had the intense application of the knowledge. As a consequence, this thesis analyzes the knowledge management aiming to improve the PDP and it also proposes a theoretical model of knowledge management. This model uses five steps (creation, maintenance, dissemination, utilization and discard) through the verification of the occurrence of four types of knowledge conversion (socialization, externalization, combination and internalization) that it will improve the knowledge management in this process. The intellectual capital in Small and Medium Enterprises (SMEs) managed efficiently and with the participation of all employees has become the mechanism of the creation and transference processes of knowledge, supporting and, consequently, improving the PDP. The expected results are an effective and efficient application of the proposed model for the creation of the knowledge base within an organization (organizational memory) aiming a better performance of the PDP. In this way, it was carried out an extensive analysis of the knowledge management (instrument of qualitative and subjective evaluation) within the Design department of a Brazilian company (SEBRAE/RN). This analysis aimed to know the state-of-the-art of the Design department regarding the use of knowledge management. This step was important in order to evaluate in the level of the evolution of the department related to the practical use of knowledge management before implementing the proposed theoretical model and its methodology. At the end of this work, based on the results of the diagnosis, a knowledge management system is suggested to facilitate the knowledge sharing within the organization, in order words, the Design department

Oil spill on the sea, accidental or not, generates enormous negative consequences for the affected area. The damages are ambient and economic, mainly with the proximity of these spots of preservation areas and/or coastal zones. The development of automatic techniques for identification of oil spots on the sea surface, captured through Radar images, assist in a complete monitoring of the oceans and seas. However spots of different origins can be visualized in this type of imaging, which is a very difficult task. The system proposed in this work, based on techniques of digital image processing and artificial neural network, has the objective to identify the analyzed spot and to discern between oil and other generating phenomena of spot. Tests in functional blocks that compose the proposed system allow the implementation of different algorithms, as well as its detailed and prompt analysis. The algorithms of digital image processing (speckle filtering and gradient), as well as classifier algorithms (Multilayer Perceptron, Radial Basis Function, Support Vector Machine and Committe Machine) are presented and commented.The final performance of the system, with different kind of classifiers, is presented by ROC curve. The true positive rates are considered agreed with the literature about oil slick detection through SAR images presents

The Brazilian legal documents are directing the reformulation of the courses that prepare students to be teachers. Through out the country many institutions look for to fit themselves in such documents. On the other hand, other IES (Superior Education Institutions), when they are setting up such courses they looked for to be adequate to the new public politics. Based on the National Curricular Norms to form teachers for Basic Education, in tertiary level, in 2004 it was created at the CEFET-PB,the Chemistry Course (Licenciatura) to prepare people to be teachers, whose organization. This work presents the results of a research of phenomenological nature that aimed to comprehend the teachers opinions, in the range of discussions about the current politics of formation, particularly related to the CNE/CP 1 and CNE/CP 2/2002 resolutions. This work based on the curricular proposal for the Chemistry Course (Licenciatura), presents the relationship between the probationary period and the teaching practice at the CEFET-PB, in order to contribute for a reflection about these categories to clarify the teachers of the course. It started from the consideration of all changes operated in contemporary society implies changes on teacher's pedagogical practices. It was used tow instruments for the data collection: a questionnaire with open and closed questions and recordable interviews. Nine teachers form the CEFET-PB took apart and four licensed teachers. It was based in a theoretic frame as a support for discussions about the different models of teachers formation. We concluded that the representations of teachers about probationary period the practice on the activity for the teachers formation was strongly anchored in characteristic elements of the formative tendency of a institution that historically acted on a technician formation, and the results pointed to strong signs of attitudes based on a model of the technical rationality

This research, part of Applied Linguistics field, aims to analyze the language of a school blog, developed with the participation of students, as a work based on the conception of multiliteracies, focusing on the construction of different meanings. The research is carried on from the building and maintenance of a school blog, the Ieceblog, with students of Ensino Fundamental II, since 2008, in a private school in Natal-RN. The investigation of the language produced on a school blog is justified due to the interactive conceptions of writing and reading on the virtual environment. Given the fact that new technologies are a reality in the schools opened to the practices of multiliteracies, it is assumed that text, image, video, audio, non-graphic signs and hypertext intensifies the produced interaction, in which the students become real authors. In this perspective, some voices belonging to the statements that are formed through the posts and comments chosen to the analyses and reflection on the blog space as locus of productions of senses inserted in the school and the world environment, as well as for the identification of the language resources used to intensify the senses that emerge from it. From the view of dialogism conceptualized by Bakhtin Circle, the qualitative interpretive-research deepens the experience of a school blog focusing on digital language in line with the vision of digital literacy. From the blog posts, a corpus that promote the exposure of different manifestations of language in the design of digital multiliteracies is elected. Thereby, the method used was the dialogical analysis of speech based on Bakhtin s studies and the Circle. The corpus was taken from the blog s posts in order to point up the different language manifestations in the following categories: (i) mood reinforced by the mockery, (ii) search for compliance with school sphere, (iii) conflicting social values and consistent complicity between sense and verbal imagery, and finally (iv) social practices that take place from and through the discursive genre. The study points to the tension between the active voices in several directions, revealing the distorted unit of posts which, under the analytical observation raises multiple meanings in a responsive manner. The analysis of the dialogue interaction in which intersperses the digital one becomes more apparent that the multiliteracies events that are mediated by language in addition to structure of the language and makes us rethink the students

Some authors have suggested that learning tasks conducted in L2 classes can motivate learners in different ways. Similarly, Interactive Whiteboards (IWB) have already been linked as drivers to engagement and enthusiasm in L2 classes, which may cause some impact on affective variables that influence learning (e.g. motivation). This crosssectional mixed-methods study aims to understand how situational motivation caused by learning tasks mediated by the IWB impact participants. We seek to answer the following research questions: (1) How does motivation as a personality trait of the learner relate to his/her additional language learning performance?, (2) How does the type of learning task mediated by the IWB impact the learner s motivation?, (3) How does motivation vary along the learning task mediated by the IWB? and (4) What is the relation between the learning task motivation and the learners perception about the task mediated by the IWB? Data collection lasted four months with 29 learners from a private language school. The instruments used were the following: (a) an initial questionnaire (adapted from the Attitudes/Motivation Test Battery by GARDNER, 2004), (b) situation-specific on-line scales to assess learners motivation in three moments: before, during and after the task, and analyze how motivation varies along the task; (c) class observations and field notes resulting from these observations, (d) participants end-of-course grades to understand the connection between academic success and their motivational profiles and (e) a final questionnaire with the qualitative purpose to know learners perceptions about the tasks mediated by the IWB. Our theoretical framework is based on Task-Based Learning and cognitive aspects present in tasks (WILLIS, 1996; SKEHAN, 1996), theories on motivation and second language learning (GARDNER, 2001; DÖRNYEI e OTTÓ, 1998; DÖRNYEI, 2000; 2002) and conceptions about L2 learning mediated by technology (GIBSON, 2001; OLIVEIRA, 2001; MILLER et al, 2005). Our results do not point out to a significative correlation between learners end-of-course grades and their motivational profiles. However, they indicate that there is some variability in situational motivation along the tasks, even among learning tasks from the same type. Furthermore, they show that learners report different perceptions for each learning task and that the impact of the IWB on participants did not have a large proportion
