A proposta do estado empregador de ultima instância e o experimentalismo democrático: uma reflexão teórica sobre a compatibilidade desses dois programas

This paper aims to make a theoretical reflection on the theoretical compatibility between the program State Employer of Last Resort (ELR) and the Democratic experimentalism (ED). The ED arises in political thought as an alternative to neo-liberal and social democratic programs in order to rescue the discussion about the institutional organization of society and the market economy. About the involuntary unemployment, it proposes tax changes incidents on payroll and proposes work fronts to the most vulnerable or poorly trained. The hypothesis of this paper is that this approach is compatible with the ELR program, the post- Keynesian line. The ELR is presented as transgression of the mainstream of economic thought by proposing that the State acts as guarantor of employment, working as a stabilizing anchor for the economy. On the edge, the ELR proposes eliminate completely involuntary unemployment. The implementation of the ELR, however, requires the construction of institutions that aim to remake the market economy, as well as deepen and energize politics and democracy, goals that are part of the ED program. Thus, the ED would, in theory, an environment conducive to innovative policies guarantors of training and occupation of the individual, essential for their emancipation institutional environment. In Brazil, which has serious infrastructure problems and qualification of manpower, such a program has enormous potential benefit. However when transposed to the Northeast of Brazil through the Plan for the region based on the principles of the ED and the hypothetical coupling to the ELR could not confirm or reject the hypothesis sub-compatibility of these two theoretical frameworks. The findings point to a partial convergence between these two programs

A literatura na sala de aula: uma alternativa de ensino transdisciplinar

The present thesis studies the appropriate education of the literary gender based in an approach of trans-disciplinary teaching. The main objectives will be to survey the degree of trans-disciplinarity of the literary reading in classrooms and to propose the literary reading as an alternative of trans-disciplinary teaching. The theoretical contributions, which sustain the lines of central argument of this thesis, are related to the critical theories on the epistemological and methodological crisis in the speech of the modernity; the emergency of an emerging paradigm under the optics of the speech of the post-modernity; the theories concerned to curriculums and their interrelations with the school teaching; the theories of the complexity and of the inter and trans-disciplinarity; theories of the reading and of the literature, more precisely the literary semiology and the aesthetics of the acceptance; theories about the pedagogic mediation starting from presupposed and trans-disciplinary principles. The methodological foundations, of the type inter and trans-disciplinary, which anchor the approach of the study is related to a line of qualitative analyses applied the teaching-learning situation accomplished during the data collection during the empiric stage of the research. The analyzed corpus is composed of episodes originated from the classes with literary texts accomplished in the months of June and December of 2005, under the orientation of a complex and trans-disciplinary didacticism. The involved subjects are students in the age group of 9 and 13 years of age from a public school in the county of Cabo de Santo Agostinho, in the State of Pernambuco. Starting from the discoveries found during the research, so much bibliographical, as that of the field, it is possible to conclude, among other things, that the literary reading, when mediated accordingly in the classroom, is a trans-disciplinary object of high degree, because the literary reading can allow and make it possible to the real reader, through a necessary process of speculation on life and its unfolding, solid reflection around the individual and collective occurrences so much in simpler instances as in more complex ones

Representações sociais de discentes sobre universidade: um estudo psicossocial entre ingressantes do vestibular e da seleção ProUni

Demand for access to higher education to put in test the education Brazilian system in view of the surplus of selective processes of public universities, people without option to pay their studies at this education level. In this context, it has arisen the University for All(Universidade para Todos)Program, the ProUni, from Ministry of Education - MEC, created by the Federal Government in 2004, and that it aims the granting of full and partial scholarships in private higher education institutions, graduate courses in sequential specific training, low-income Brazilians students who do not have higher-level degree. Created by the Provisional Measure No 213/2004 and institutionalized by Law No. 11096 of January 13, 2005, the ProUni offers, however, the exemption of some taxes to those institutions that join the program. This is one of the privileged time for the study of Social Representations by offering the researcher, a living laboratory, natural environment, the confrontation between the established and new. In time like this people are challenged to incorporate the new system to the pre-existing one, aiming it through a strangeness of what was so familiar. It is through this game of social forces that we developed the present study with 196 entering higher education, of these are 116 of selective vestibular system and 80 of the ProUni selective system. We opt by the procedures for data collection in order to have access to the circulating senses, in addition to the streamlined responses. With foundation in Abric, we perform the test the Free Association of Words, then analysed by the software and by EVOC Content of the type theme as Bardin. Besides, we require of the subjects, a writing on the study object university later analysed by the software ALCESTE. The results point out to a representation strongly rooted in social factors such as more traditional socio-cultural elements: the beliefs, values, the symbols. It is unique in both groups of subjects: among those entering by the selective ProUni system, there was a stronger anchor in that it does not make inquiries about the program. At the same time, there is a stronger presence of objectivation, entering the selective vestibular system in order that they explained with a value judgement on the programme. It is suggested further studies considering the embryonic state of social representation, as recent as the social purpose that triggered. It would be relevant even the replication of the same research with other people in order to strengthen the power of the theorising of empiria available

Modelagem numérica de estruturas de contenção atirantadas em areia

A numerical study on the behavior of tied-back retaining walls in sand, using the finite element method (FEM) is presented. The analyses were performed using the software Plaxis 2D, and were focused on the development of horizontal displacements, horizontal stresses, shear forces and bending moments in the structure during the construction process. Emphasis was placed on the evaluation of wall embedment, tie-back horizontal spacing, wall thickness, and free anchor length on wall behavior. A representative soil profile of a specific region at the City of Natal, Brazil, was used in the numerical analyses. New facilities built on this region often include retaining structures of the same type studied herein. Soil behavior was modeled using the Mohr-Coulomb constitutive model, whereas the structural elements were modeled using the linear elastic model. Shear strength parameters of the soil layers were obtained from direct shear test results conducted with samples collected at the studied site. Deformation parameters were obtained from empirical correlations from SPT test results carried out on the studied site. The results of the numerical analyses revealed that the effect of wall embedment on the investigated parameters is virtually negligible. Conversely, the tie-back horizontal spacing plays an important role on the investigated parameters. The results also demonstrated that the wall thickness significantly affects the wall horizontal displacements, and the shear forces and bending moments within the retaining structure. However, wall thickness was not found to influence horizontal stresses in the structure

Avaliação do desempenho de uma cortina de estacas espaçadas, atirantada, em areia

It is presented the analysis of a retaining wall designed for the basement of a residential building, located in Natal/RN, which consists in a spaced pile wall, anchored by tiebacks, in sand. This structure was instrumented in order to measure the wall s horizontal movements and the load distribution throughout the anchor fixed length. The horizontal movements were measured with an inclinometer, and the loads in the anchors were measured with strain gages, installed in three places throughout the anchor fixed length. Measurements for displacement were done right after the implementation of each stage of the building and right after the conclusion of the building, and the measurements for loads in the anchors were done during the performance test, at the moment of the locking off and, also, right after the conclusion of the building. From the data of displacement were obtained velocity and acceleration data of wall. It was found that the time elapsed on braced installation was decisive in the magnitude of the displacements. The maximum horizontal displacement of wall ranged between 0,18 and 0,66% of the final depth of excavation. The loads in the anchors strongly reduced to approximately half the anchor fixed length, followed an exponential distribution. Furthermore, it was found that there was a loss of load in the anchors over time, reaching 50% loss in one of them

Contribuições de uma unidade de ensino potencialmente significativa UEPS para o ensino de ecologia em escola pública da educação básica

The research aims to evaluate the contributions of a teaching unit to enhance the learning contents ecological green areas in elementary school. The work was conducted with elementary students in a public school in Natal-RN. We sought to identify the students´ previous knowledge about the contents of ecology, develop and implement a Potentially Meaningful Teaching Units PMTU; assess learning of ecological concepts in Teaching Unit Potentially Significant; assess the contribution of interpretative trail as strategy teaching to learning content ecology. The survey of students´ previous knowledge through the pre-test was essential to identify the appropriate subsumers and partially correct, since they served as "anchor" for further expansion of scientific concepts contained in this research. The green areas of the school as an educational, contributed the motivational aspect, as students were protagonists throughout the entire process of teaching and learning. The method of stimulated memory was effective to evidence learning ecological concepts in interpretive trails. The use of diverse activities organized on a PMTU promoted intellectual autonomy of the students and facilitated the acquisition of new meanings through progressive differentiation, and integrative reconciliation consolidation of ecological content and concepts related to biotic and abiotic factors on the basis of the central ideas thematic Life and Environment. The development of procedural skills to capture and share meanings, observe, collect and record data, hypotheses, ability to explain, to apply knowledge to solve problem situations, argue, identify, compare, differentiate and relate concepts, negotiate meanings, reflecting Critically, systematize data was evidenced. Collaborative activities promoted the incorporation of attitudinal contents as developing respect for differences, learn to work in teams to plan, develop and implement actions together for citizenship and environmental responsibility. The application of the Potentially Meaningful Teaching Units PMTU showed evidence of Critical meaningful learning ecological concepts covered in elementary school.

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

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

Modelagem numérica de uma estrutura de contenção de estacas espaçadas atirantadas em areia

Retaining walls design involves factors such as plastification, loading and unloading, pre-stressing, excessive displacements and earth and water thrust. Furthermore, the interaction between the retained soil and the structure is rather complex and hard to predict. Despite the advances in numerical simulation techniques and monitoring of forces and displacements with field instrumentation, design projects are still based on classical methods, whose simplifying assumptions may overestimate structural elements of the retaining wall. This dissertation involves a three-dimensional numerical study on the behavior of a retaining wall using the finite element method (FEM). The retaining wall structure is a contiguous bored pile wall with tie-back anchors. The numerical results were compared to data obtained from field instrumentation. The influence of the position of one or two layers of anchors and the effects of the construction of a slab bounded at the top of the retaining wall was evaluated. Furthermore, this study aimed at investigating the phenomenon of arching in the soil behind the wall. Arching was evaluated by analyzing the effects of pile spacing on horizontal stresses and displacements. Parametric analysis with one layers of anchors showed that the smallest horizontal displacements of the structure were achieved for between 0.3 and 0.5 times the excavation depth. Parametric analyses with two anchor layers showed that the smallest horizontal displacements were achieve for anchors positioned in depths of 0.4H and 0.7H. The construction of a slab at the top of the retaining wall decreased the horizontal displacements by 0.14% times the excavation depth as compared to analyses without the slab. With regard to the arching , analyzes showed an optimal range of spacing between the faces of the piles between 0.4 and 0.6 times the diameter of the pile

Querido diário: a construção identitária de alunos da EJA em diários pessoais

This study aims to present analyses of our research, documentary type, which investigates the construction of cultural identities of the Youth and Adults Education (Educação de Jovens e Adultos – EJA), level III, in a public school in the city of Natal/RN, through personal diaries produced in the school environment. In a qualitative-interpretive approach, we anchor our identity studies (BAUMAN, 2001, 2005, 2006; HALL, 1987, 1997, 2011, 2012) that bring us the idea that identities are built and rebuilt by social relations that we do. To this end, we start from a conception of language that does not require pre-conceptions because they are based on the utterance itself. Therefore, we have analyzed the utterances produced by these students from the perspective of Bakhtin Circle (BAKHTIN, 1988, 1993, 1998, 2002, 2010, 2012), which deals with the discursive construction emerging from intersubjective processes of verbal interaction, in a dialogical relationship of the self to the other, by the otherness and the heteroglossia. Moreover, our study is also guided by the guidance on speech genres (BAKHTIN, 2010) and personal journal (LEJEUNE, 2008; MACHADO, 1998, 2009). We join to Applied Linguistics (MOITA LOPES, 2006, 2009) because we believe that this research focuses on a social practice in which language plays a central role and seeks to demonstrate how the speeches of the subject students of EJA, in personal journals, are building tools not only of their identities, but also knowledge and social life of the position that this subject student takes. We conclude this work in a perception of cultural identities that are built by the subject students of EJA, because the results suggest that the identities of these students are fluidly constructed by the representation that the student makes of his or her school, of being student of EJA and how he or she is a student of this educational modality. Thus, through our work, we plan to present another look about the identity or identities of a student of EJA, pointing an insight of this subject.
