Desenho de mecanismos para estratégia de inovação corporativa

As empresas que optam pela inovação como estratégia de crescimento desenvolvem projetos para a exploração de oportunidades em novos produtos, serviços e mercados. Tais projetos lidam com situações de alta assimetria de informação e, consequentemente, riscos de conflitos de interesses entre agente e principal. Para viabilizar a alocação de recursos em tal situação, a gestão de projetos dentro das organizações busca minimizar os custos de agência atuando diretamente na causa raiz. Ao financiar o empreendedorismo, o venture capital (VC) e sua versão corporativa, o corporate venturing (CV), lida com a assimetria de informação de uma forma diferente. Ao invés de diminuí-la diretamente, os VCs e os CVs implementam mecanismos que os permitem explorar situações de alta assimetria de informação, e ao mesmo tempo, controlar os custos de agência decorrentes desta. Quando comparado às práticas de gestão de projetos nas organizações, as práticas de seleção, financiamento, contratos, organização e incentivos empregadas na gestão de projetos de VCs e CVs constituem um desenho de mecanismo mais eficiente para o desenvolvimento do empreendedorismo. Ainda que cada um desses cinco componentes do mecanismo empregado pelos VCs e CVs possa ser identificado na gestão de projetos corporativos, nas organizações pesquisadas, não foi possível identificar a integração desses componentes promovendo um mecanismo coeso. A prática de financiamento de projetos é a que apresentou a maior diferença. O entendimento de como as práticas de gestão de projetos podem ser configuradas num desenho de mecanismo que viabiliza o trato da assimetria de informação, ao mesmo tempo em que minimiza seus efeitos indesejáveis em termos de custos de agência, oferece às organizações uma forma gerenciável de promover um ambiente corporativo onde o empreendedorismo possa florescer. Condição necessária para inovações de maior impacto.

Diretrizes para a integração dos requisitos de construtibilidade ao processo de desenvolvimento de produto de obras repetitivas

O processo de desenvolvimento de produto (PDP) convencional tende a enfatizar a definição do produto sem levar em conta as necessidades da produção. Dentre as várias iniciativas que têm sido desenvolvidas para integrar estas duas interfaces, este trabalho destaca a construtibilidade, a qual visa, por meio de intervenções no projeto do produto e do processo, garantir a facilidade de execução da obra durante as etapas de construção e manutenção. No entanto, poucos estudos têm se dedicado à consideração dos requisitos de produção no PDP de obras de menor complexidade. Assim, o objetivo principal deste trabalho consiste em propor diretrizes para a integração dos requisitos de construtibilidade ao PDP de obras repetitivas, que abrangem conjuntos residenciais e prédios altos com mais de dez pavimentos. A partir de dois estudos de caso realizados em uma empresa construtora e incorporadora de condomínios horizontais de Porto Alegre, foram propostas as seguintes diretrizes: (a) adequação do projeto do produto às limitações impostas pela tecnologia construtiva disponível; (b) análise crítica do projeto com apoio de indicadores; (c) construção e avaliação de uma unidade modelo; e (d) desenvolvimento de mecanismos de aprendizagem em relação à construtibilidade. A diretriz (b) inclui a proposição de um check-list de boas práticas com vistas a avaliação dos níveis de construtibilidade do projeto do produto e do processo. Além disso, este trabalho indicou que, a ocorrência de determinadas não conformidades durante a execução, tais como má qualidade dos materiais e erros de execução, resultam em perda do valor agregado para o cliente interno. Sendo assim, constatou-se que o esforço pela melhoria da construtibilidade deve incluir a consideração de meios para assegurar que a facilidade de execução prevista no projeto do produto e do processo, seja concretizada na etapa de construção.

Coordenação na cadeia produtiva de ovinocultura : o caso do Conselho Regulador Herval Premium

O presente estudo foi desenvolvido a fim de identificar iniciativas de coordenação na cadeia de ovinocultura. Após um período de desvalorização da ovinocultura, a cadeia produtiva encontra-se em um novo cenário frente as oportunidades de mercado para carne ovina e ao potencial produtivo da ovinocultura no estado do Rio Grande do Sul. Diante deste novo cenário, produtores rurais da região da Serra do Sudeste buscaram uma forma de atuação diferenciada na cadeia vislumbrando obter resultados econômicos mais satisfatórios a partir da produção, através da agregação de valor aos produtos e integração dos agentes, aumentando a competitividade da cadeia de ovinocultura. Esta proposta de atuação originou o Conselho Regulador do Cordeiro Herval Premium. Objetivo geral do estudo é analisar a forma de atuação da iniciativa de coordenação do Conselho Regulador do Cordeiro Herval Premium na cadeia de ovinocultura do Rio Grande do Sul. Para atingir este objetivo no referencial teórico foram utilizadas as teorias de cadeia produtiva, cadeia de suprimentos, canais de distribuição, coordenação e alianças estratégicas. Como método de pesquisa foi utilizado o estudo de caso do Conselho Regulador do Cordeiro Herval Premium. A análise dos dados primários coletados a partir das entrevistas com os agentes participantes e dos dados secundários referentes a atuação da iniciativa de coordenação, permitiu a descrição do caso e obtenção dos resultados da pesquisa. Quais sejam: o Conselho Regulador do Cordeiro Herval Premium atua na cadeia da carne ovina como uma organização associativa de produtores com objetivo de coordenar a oferta de cordeiros oriundos de distintos estabelecimentos na região da Serra do Sudeste, através de um programa de seleção que garante padrão de qualidade e origem dos produtos, agregando valor a carne ovina. A coordenação na cadeia produtiva é exercida via aliança estratégica formada entre o Conselho e dois distribuidores. O Conselho coordena a cadeia de suprimentos de carne ovina, na medida que organiza o abate de cordeiros e fornece o produto de acordo com as exigências dos consumidores para atender a demanda do mercado. Por sua vez a aliança do Conselho com os distribuidores garante a estabilidade de um canal de distribuição constante para o escoamento da produção dos participantes do programa, o que lhes permite segurança de remuneração e fluxo de renda ao longo do ano.

Competitividade no agronegócio: proposta de modelo para elaboração de estratégia de integração de cadeias para os defensivos agrícolas – o caso do café

A produção sustentável de alimentos é fundamental para suportar o crescimento populacional. Segundo estimativa da FAO, se a população atingir 9,1 bilhões de habitantes em 2050, a produção de alimentos deverá crescer 70%, e a produção nos países em desenvolvimento deverá dobrar. Ou seja, a maior parte do crescimento vem de países emergentes, onde se concentra o maior potencial de crescimento agrícola. Com o aumento populacional e o aumento da renda da população destes países emergentes, há aumento na demanda por produtos de melhor qualidade, fazendo com que o crescimento na produção de alimentos seja não somente de quantidade, mas também, de qualidade e valor. Portanto, a maior a exigência em termos de segurança do alimento, faz com que rastreabilidade e transparência com relação ao uso de tecnologias de produção se transformem em fatores que influenciam a aceitação de alimentos por parte dos consumidores do mercado doméstico e também de mercados internacionais. Neste contexto, o varejo ganha importância estratégica pela proximidade do seu negócio com o consumidor final. Ele é o primeiro elo da cadeia a receber informações sobre o cliente em termos de comportamento de compra e demandas, podendo assim, repassá-las aos outros elos da cadeia chegando até os produtores, que tem que ajustar suas práticas em geral, e principalmente, as práticas agronômicas, no que diz respeito à qualidade e a segurança do alimento. As empresas de insumos e as agroindústrias, que contribuem para uma produção agrícola sustentável terão a preferência dos produtores rurais e varejistas, que tem a missão de entregar produtos de qualidade, seguros, de forma conveniente para o consumidor final que é o elo capaz de movimentar a cadeia em uma única direção - a da agricultura sustentável. É neste contexto que as empresas de defensivos agrícolas devem desenvolver suas estratégias de negócio. Torna-se necessário ter maior “controle” sobre a cadeia, visando o uso correto de seus produtos, visando contribuir para a agricultura sustentável, ganhando participação de mercado e/ou aumentando sua rentabilidade. Para isso, algumas empresas têm desenvolvido estratégias de coordenação de cadeias, ou “food value chain”, com alguns casos exitosos. Neste trabalho, é proposta metodologia para o desenvolvimento e implementação de estratégias de “food value chain” para os defensivos agrícolas. Ao final do trabalho, conclui-se que existem ganhos importantes para a empresa que adota este tipo de estratégia; entretanto, há um aumento na complexidade da operação. Por isso, é uma escolha importante, que deve ser parte da missão da empresa.

As relações da tríplice hélice no setor da carcinicultura do Rio Grande do Norte: uma análise a partir das abordagens da imersão social e da dependência de recursos

This work consists in a study of the Shrimp Industry in the state of Rio Grande do Norte, whose central issue relates to the understanding of how the Triple Helix (University, Government and the productive sector) interrelationship limits or expands the industry s innovation process. The study aims to understand how the Triple Helix relationship interferes in the innovation process of shrimp in Rio Grande do Norte. As the knowledge becomes the resource key for production methods, the generation of new technologies, new products and processes which demands joint and integrated action of the institutions comprising the Triple Helix: University, Government and productive sector, which possess the essential resources to innovate the process and can be maximized from cooperative relationships between the referred Institutions. Thus, in this work, it was sharply used the pioneering studies of Sabato and Botana (1968) regarding the cooperation relationship between the scientific-technological sphere, the governmental and the productive base, and studies on the Triple Helix approach, proposed by Etzkowitz and Leydesdorff (2000), in which the university has a key role in the process of technological and innovative development of countries and regions, and under which it is assigned to the very University - the character of the entrepreneurial institution, through the concept of entrepreneurial University. Aiming to overcome the criticism of Cooke (2005), regarding the limitations of the Triple Helix approach, in this study it was used - as analytical perspectives - the perspective of social immersion (Granovetter, 1985, 2005) and the theory of resources dependence (PFEFFER; SALANCIK, 1978). The analytical perspectives presented in here, despite of the different assumptions, are essential to eliminate the bias that one only approach can lead (ASTLEY; VAN DE VEM; 2007). The authors arguments focus on the fact that the integration is possible if the researcher acknowledged that different perspectives may have different descriptions of the same phenomenon. As a research strategy, this study is characterized as a study case, along with the proposed objectives - the qualitative method was used as an approach and, depending on the gathering of the sector s historical, a sectional longitudinal view approach was applied (VIEIRA, 2004). The primary and secondary data were used in order to understand the sector s evolutionary process and its inter-institutional relations - regarding the shrimp culture in Rio Grande do Norte - to promote the development, as the content was used for the technical analysis (BARDIN, 1977). The approach of social immersion and resources addiction dependence made it possible to understand that relationships are established within and between each sphere (university, government and productive sector) characterizing a network of low density relationships and strongly internal and external dependence. Based on the speech of Etzkowitz and Mello (2006), a successful Triple Helix strategy of innovation requires not only the involvement and commitment of the parts, within the institutional sphere and among them, but also the development of mechanisms to coordinate the multiple and complex interactions and interfaces, focusing on promoting both environment and context for innovation and learning; it can be acknowledge from study results that the shrimp in the State of the RN, although there are several institutional mechanisms to promote greater integration and technological development, has been presented disjointed - both internally and between the spheres - and under no legitimate practice when facing the innovational promotion and integration institutions. Due to those factors, the central institutions of the network are crucial to the promotion of innovations, spreading through their direct contacts the importance factor of the sustainable competitive activity in the world market and on the national level. However, it may be concluded, from the data, that the Triple Helix relations are interfering in a negative way on what concerns the promotion of innovations in the shrimp industry in RN

Potencialidades de cultivo de macroalgas no litoral do Rio Grande do Norte (NE, Brasil): uma perspectiva de integração de dados ambientais em sistemas de informação geográfica (SIG)

Since centuries ago, the Asians use seaweed as an important source of feeding and are their greatest world-wide consumers. The migration of these peoples for other countries, made the demand for seaweed to increase. This increasing demand prompted an industry with annual values of around US$ 6 billion. The algal biomass used for the industry is collected in natural reservoirs or cultivated. The market necessity for products of the seaweed base promotes an unsustainable exploration of the natural banks, compromising its associated biological balance. In this context, seaweed culture appears as a viable alternative to prevent the depletion of these natural supplies. Geographic Information Systems (GIS) provide space and produce information that can facilitate the evaluation of important physical and socio-economic characteristics for the planning of seaweed culture. This objective of this study is to identify potential coastal areas for seaweed culture in the state of Rio Grande do Norte, from the integration of social-environmental data in the SIG. In order to achieve this objective, a geo-referred database composed of geographical maps, nautical maps and orbital digital images was assembled; and a bank of attributes including physical and oceanographical variables (winds, chains, bathymetry, operational distance from the culture) and social and environmental factors (main income, experience with seaweed harvesting, demographic density, proximity of the sheltered coast and distance of the banks) was produced. In the modeling of the data, the integration of the space database with the bank of attributes for the attainment of the map of potentiality of seaweed culture was carried out. Of a total of 2,011 ha analyzed by the GIS for the culture of seaweed, around 34% or 682 ha were indicated as high potential, 55% or 1,101 ha as medium potential, and 11% or 228 ha as low potential. The good indices of potentiality obtained in the localities studied demonstrate that there are adequate conditions for the installation of seaweed culture in the state of Rio Grande do Norte

Coordenação entre as respostas da catalase e da ascorbato peroxidade em folhas de feijão caupi submetidas a diferentes fontes de peróxido de hidrogênio

The plants are often exposed to variations in environmental conditions that may trigger metabolic disturbances leading to a consequent loss in productivity of crops. These stressful conditions usually induce an accumulation of reactive oxygen species (ROS) in the cell, a condition known how oxidative stress. Among these species, hydrogen peroxide (H2O2) is an important molecule involved in numerous signaling mechanisms. The present study aimed to understand the relationship between the different enzymatic mechanisms of elimination of H2O2 by catalase (CAT) and ascorbate peroxidase (APX) in leaf tissues of seedlings of the species Vigna unguiculata L. Walp, under conditions of oxidative stress induced by application of CAT inhibitor, 3-amino-1,2,4-triazole (3-AT), and H2O2 itself on the roots. Three experiments were conducted. The first experiment was performed applying the compound 3-AT (5 mM) during the time (hours). In the second experiment, seedlings were exposed to different concentrations of H2O2 (2.5, 5.0, 7.5, 10 mM) for 48 h. The third strategy included the pre-treatment with H2O2 (2.5 mM) for 24 h, followed by subsequent treatment with the inhibitor 3-AT and recovery control condition. Treatment with 3-AT causes a strong inhibition of CAT activity in leaf tissues accompanied by an increase of activity of APX. However a decrease in oxidative damage to lipids is not observed as indicated by TBARS. It was observed that activity of APX is directly linked to the content of peroxide. Inductions in the activities of CAT and APX were observed mainly in the seedlings treated with 2.5 mM H2O2. This can be associated with a decrease in oxidative damage to lipids. In contrast, one same tendency was not observed in treatments with higher concentrations of this ROS. These results suggest that the concentration of 2.5 mM H2O2 can induce responses antioxidants later in seedling cowpea. This concentration when applied as pre-treatment for 24 h promoted an induction systems removers CAT and APX, both in activity and in terms of gene expression. However this increment was not observed in the recovered plants and the plants subsequently subjected to 3-AT. Additionally, the pretreatment was not sufficient to attenuate the inhibition of CAT activity and oxidative damage to lipids caused by the subsequent application of this inhibitor. The results showed that the application of 3-AT and H2O2 in the root systems of seedlings of cowpea promote changes in the parameters analyzed in leaf tissues that indicate a direct response to the presence of these factors or systemic signaling mecanisms. H2O2 appears to activate the responses of two antioxidant systems in this study thar does not promote greater protection in case of additional treatment with 3-AT. This demonstrates the importance of the CAT system. In this work, complete results indicate that there is a difference between the signaling and the effects caused by exposure to H2O2 and by treatment with 3-AT

Medo e violência na cidade: imagens, discursos e sociabilidade nas praças de João Pessoa - PB

The present work analyses and discusses the sociability in the culture of contemporary cities focusing on the theme of fear and violence in the daily life of squares in the city of João Pessoa-PB. We analyse the relations between places in town and make correlations of history and setting of neighborhoods with the process of urban growth, including recent interventions of public authorities in their public spaces. We observed in this dynamics social attitudes and actions that range from a desired peaceful coexistence to social exclusion. Thus, we discuss, based upon the imaginary vision, that the squares exist as a locus of equality, citizenship and political, and, also, as a space for everyone, despite the existence of symbolic forces working towards segregation and privatization, ruled in fear and violence. We aimed to investigate the different symbolic logics from the issue of fear and violence that allows the exclusion and the inclusion of groups and individuals in the quotidian use of public spaces of contemporary cities. We believe that the social action is demarcated by violence ant its corollary, the social fear, and operates based on the logic of a relational game always confrontational but experienced in different forms according to the social segment or group under study. We used a qualitative and quantitative methodology relating data and statistical analysis with categories created for the understanding of subjective factors. Our analyses combined ethnographic elements, periodics research and images of the city and its spaces, with the contribution of a survey that allowed comparisions of five squares of neighborhood based on the daily life under investigation. Our proposal was to deepen the investigations related to the public space of contemporary cities, expanding the look on João Pessoa and its cultural dynamics with an analysis of discourses, images, the collective imaginary and the social appropriation of the spaces based on fear and violence. The research accomplished in different areas and the analysis of images and speeches published in newspapers reports, books, advertising etc. allowed the approach of differentiated patterns of sociability in the same urban process. The neighborhoods in study are indeed spatially and economically distanced and the process of creation and construction of squares occurred in very different ways in the respective location. We defend the thesis that neighborhood community squares provide reinvigorated spaces and public spheres in the urban process and in the dynamics of sociability in the cities. These squares are also social spaces par excellence for the perception of the logic of individualism and segregation so marked by fear and violence in contemporary cities

Mecanismos sócio-genéticos da representação social de trabalho docente por grupos de licenciandos de física e de química da Universidade Federal do Rio Grande do Norte

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

Gestão ambiental em cadeias produtivas agroindustriais: um estudo em um aglomerado produtivo da caprinovinocultura no Estado do Rio Grande do Norte

This thesis aims to investigate the perception and behavior of goat and sheep rural producers from Central Cabugi Region of Rio Grande do Norte state, in terms of the sector competitiveness, the cooperation mechanisms, information and environmental practices integration in the supply chain, including their customers, and also among the local producers and other institutions that support this agribusiness cluster. The research problem is related to the environmental impacts from goat and sheep breeding. This problem can also be intensified by the organization of producers in a cluster. Then, it is important to examine how the environmental issues are considered by the rural producers and their perception of their suppliers, customers and the institutions that support this activity. The methodology used in this work involved literature review of the topics of supply chain management, green supply chain, clusters development and sustainable livestock. An exploratory survey research was also conducted by personal interviews using questionnaires. Three statistic techniques were used to compile the gathered data: descriptive statistics, cluster analysis, and Chi-square tests. Two clusters were found in this study, however, the entire sample believes the sector of goat and sheep breeding is a medium competitive activity. On the other hand, for the variables of the importance of environmental practices for competitiveness , perception of environmental impacts and environmental benefits from farm vegetation management , the research found 2 distinct groups of individuals when those variables were analyzed together the green supply chain management group of variables in the cluster analysis. Beyond competitiveness perception, no degree of difference was found for the use of insecticides too. The chi-square tests present that producers having at least elementary education, lands bigger 100 hectares and located in the cities of Angicos or Lajes tend to have a higher perception to supply chain management and environmental awareness issues than those with no or incomplete first-level education, producing in lands smaller than 100 hectares and located in the cities of Afonso Bezerra or Pedro Avelino. The chi-square tests also show the amount of milk produced, family s income and associational condition are not related with the variables used in the clusters composition. In this context, this work contributes to planning clusters development strategies and enhancing the production chain sustainability. This Master of Science Thesis can also help to introduce the environmental variable in the project, assessment and monitoring of development policies as well

Mecanismos de desgaste de poliuretano em ensaios de microabrasão

Wear mechanisms and thermal history of two non-conforming sliding surfaces was investigated in laboratory. A micro-abrasion testing setup was used but the traditional rotative sphere method was substituted by a cylindrical surface of revolution which included seven sharp angles varying between 15o to 180o. The micro-abrasion tests lead to the investigation on the polyurethane response at different contact pressures. For these turned counterfaces with and without heat treatment. Normal load and sliding speeds were changed. The sliding distance was fixed at 5 km in each test. The room and contact temperatures were measured during the tests. The polyurethane was characterized using tensile testing, hardness Shore A measurement, Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Thermomechanical Analyze (TMA). The Vickers micro-hardness of the steel was measured before and after the heat treatment and the metallographic characterization was also carried out. Worn surface of polyurethane was analysed using Scanning Electron Microscope (SEM) and EDS (Electron Diffraction Scanning) microanalyses. Single pass scratch testing in polyurethane using indenters with different contact angles was also carried out. The scar morphology of the wear, the wear mechanism and the thermal response were analyzed in order to correlate the conditions imposed by the pressure-velocity pair to the materials in contact. Eight different wear mechanisms were identified on the polyurethane surface. It was found correlation between the temperature variation and the wear scar morphology.

Ave! Mossoró! : os mecanismos discursivos sobre o episódio da resistência ao bando de Lampião

This thesis has as objective the interdiscursive relations in the process of language construction in use in the poetic and in the journalistic spheres, with the purpose of perceiving how the genre news is constituted in different fields of social activity, as well as to analyze the argumentative processes that structure the written discourses about the resistance episode to the group of Lampião in Mossoró in the year of 1927. The corpus of the research is constituted by the news of the period informed in the printed newspapers: Correio do povo and O Nordeste, both from Mossoró/RN, and the narratives presented in the cordéis de acontecido : Mossoró in the resistance to the group of Lampião; Lampião in Mossoró in 1927, and Mossoró attacking to the group of Lampião, all potiguar poets. The analysis of the texts had as theoretical background the studies of: The texts analysis had as theoretical background The Discourse Analysis; The Argumentation Theory and the studies about Discourse Genres. We focused our discussion in the emphasis given to the news in the discursive perspective of the social-historic memory constructed in the cordéis, from ideological values (political, economical, religious etc.) that pass to be a fundamental element in the constitution of the image of the resistance. Methodologically, this is a documental research, since it makes use essentially of the written document. Regarding to the nature of the data, the research is characterized as a qualitative one. In the analysis, we considered the argumentative techniques adopted in the defense of the thesis, the meaning effects suggested, and the genres mentioned, that revealed to us the manner in which the episode was informed by the newspapers and the cordéis. That way, we affirm, based on the positions assumed by the announcers of the genres analyzed who defended clearly positions in favor of the defense of Mossoró, that the relation between both is captured interdiscursively, since they are asked by the same ideology, and converge to the same discursive formation, defending identical positions, and structuring their discussions with resembling argumentative techniques, reason by which take us to believe that the discourse presented in that social activity demonstrates and develops traces of a manipulation of the subject. In this case, the discursive construction of the text points towards determining standard of repetition, since the linguistic context is characterized in the journalistic field, and in the poetic field assuming, in the first instance, a local expression

Mecanismos de controle do trabalho escolar em propostas de escrita narrativa em livros didáticos de português (1974-2009)

This essay aims at investigating the writing proposals of Portuguese textbooks (LDP Livros Didáticos de Português) for Middle School (EF Ensino Fundamental), from 6th to 9th grade, from the 70s to 2009. It aims to check, though the discourse reported in the Portuguese Textbook, the control directed to the practice of the teacher and the student to do in the teaching situations. Theoretically, we search for contributions that come from the Discourse Analysis of French filiation, so we can analyze the ideological constructions present in the discourse of the ―LDP‖ more specific lly the control directed to the te cher nd student the users of the book, in writing activities. It started from a corpus of 63 textbooks whereof the following steps were performed: a) mapping of the writing proposals contemplated in the ―LDP‖ of high school; b cutting in the selection of propos l ccording to the rese rch go ls intended (writing proposals of narrative texts). After mapping the writing proposals presented in the ―LDP‖ bout the criteri mentioned bove we re d the writing propos ls to ch rt the quantity of proposals of textual writing productions in each textbook (which usually follows a pattern : 12 chapters and, at the end, the writing proposal. Nevertheless, some books present 2 (two) or more writing proposals at the end of each chapter). We did a cutting in the corpus initi lly constituted 63 ―LDP‖ nd we selected 12 writing proposals of narrative texts presented in the ―LDPs‖ to present wh t we intend to n lyze. Then, we separated these proposals into two groups: 1) activities which present ―instruction guide‖ to be followed by the student; 2) writing activities that allow the student write with no need to follow a text pattern, i.e., which encourage authorship. By means of analyses, it was possible to demonstrate that, in the Basic School, generally, the writing practices concentrate, primarily, on copying activities, reproduction, rewriting and, in more advanced levels, in activities that which start from preset models, asking the students to produce text with similar themes, following the suggested structure. It is about ideals that are supposed to be followed and imitated by the students, depriving them to assume their authorship. In order to insert the student in the world of writing it s necess ry to go beyond the model of c nonic l texts pr ctice th t puts the students f r from the possibility to be ― uthors‖. In contr st to this tendency, we face, nowadays, proposals that prioritize the authorship, the creation of a style
