Responsabilidade social empresarial: percepções e práticas do empresariado salineiro do Rio Grande do Norte.

The debate around the thematic of Corporate Social Responsibility - CSR involves economic, social, cultural and symbolic aspects in the relations established between company and society. In Brazilian reality, the CSR, understood as enterprise actions, external and/or internal, that contributes to social and ambient improvement, gains greater visibility in 1990 decade. Although the significant increase of theoretical productions about CSR pertinent elements, it is still scarce the studies that treats about the relation company/society in the northeastern reality, and singularly, in Rio Grande do Norte. It was in this perspective, that, in being the salt industry one of most important in the potiguar economic history formation , the present work investigated practicies and perceptions of salt entrepreneurship about CSR. Considering all the Rio Grande do Norte salt industry history phases, since the period of the Brazil s settling, as well as the characteristics of the study object, was opted to the qualitative research, objectified in interviews half-structuralized realized with the salt segment entrepreneurs, as well as professionals of ambient management and human resources working in potiguar salt segment. The research main results indicated a coexistence between the mechanisms of management seated on personal and paternalists relations, typical of traditional salt industry, and the emergency of innovative elements typical of the modern management, like the CSR. In this context, a tension between continuity and rupture with the traditional mechanisms of management in salt entrepreneurship actions

Ciência como montagem, montagem como ciência

The thesis describes parallel possibilities between the knowledge built in theatre and in Science. The narrative is constructed through a reflexive observation of the process of making a threatical play, specifically O Tempo da Chuva by Grupo Beira de Teatro , in analogy to the process of making a scientific theory, specifically the one described by Werner Heisenberg in his book Physics and Beyond: encounters and conversations . It sets a dialog with authors/actors from various areas of knowledge, such as Edgar Morin, Werner Heisenberg, René Descartes, Paul Feyerabend, Paul Caro, Juremir Machado da Silva, Maria da Conceição de Almeida, Renato Ferracini, among others. It discusses the hypothesis that Science is the process of building and the theatrical process of building a play can also be systematized, likewise science. The thesis defends, as the complexities science may suggest, a method as a strategy. Developed throughout the process, such method could only be verified at the end, when the elements of the setting of atomic physics theories and theatre were correlated. Questions such as: the place of theatre and science in our contemporary society and the political and ethical role of artists and scientists are at the episthemological basis of this narrative which we have started, but it is not even close to a conclusion

Anaerobic biodigestion of pigs feces in the initial, growing and finishing stages fed with diets formulated with corn or sorghum

Objetivou-se avaliar a produção e a qualidade do biogás e do biofertilizante obtidos em biodigestores abastecidos com dejetos de suínos, nas fases inicial, crescimento e terminação, alimentados com dietas formuladas à base de milho ou sorgo. Foram utilizados 20 biodigestores de bancada, com tempo de retenção hidráulica de 30 dias, e cargas diárias que continham 4,0 a 6,0% de sólidos totais (ST) e 3,6 a 5,2% de sólidos voláteis (SV). Nos efluentes dos biodigestores, foram verificados teores médios de ST variando de 1,6 a 2,0% e de SV entre 1,2 e 1,6%. As reduções médias de ST foram de 57,7 a 64,7% e de SV de 61,7 a 69,0%, sendo que houve diferença somente na fase de terminação, na qual as maiores reduções médias foram para biodigestores abastecidos com dejetos de animais alimentados com dietas à base de milho. Nos biodigestores abastecidos com dejetos de animais em fase inicial e de crescimento, alimentados com dietas formuladas à base de milho, foram verificadas maiores produções médias de biogás e os maiores potenciais médios de produção de biogás. Os potenciais médios obtidos foram 0,033; 0,181; 0,685; 0,788 e 1,132 m³ por kg de afluente, estrume, ST adicionados, SV adicionados e SV reduzidos, respectivamente. Não foram verificadas diferenças quanto ao teor médio de metano no biogás entre dietas e fases. As concentrações médias dos nutrientes N, P, K, Ca, Mg, Na, Fe, Mn, Zn e Cu no afluente e efluente dos biodigestores variaram entre as dietas e fases.

Brincadeira do reisado na comunidade Cipó, Pedro II PI: mediação cultural, tradição e modernidade

This research studies the tradition of epiphany in the community of Cipó de Baixo, which belongs to the city of Pedro II, in the state of Piauí. Readings were made seeeking to emphasize the processivity of the play that navigates between permanence and change. The study starts with a social context of the community, in dialogue with the life history of the owner of the epiphany, Raimundo Milú: strong figure who, along with his family networks, as well as networks of patronage and friendship, struggles for the resistence of the play. The description of the ceremony of Kings, with its constituent parts, punctuates the remarkable character of Cipó community epiphany. This detailed understanding of the play favors the understanding of some of the social vines that serve as the basis for the warp of this cultural practice: modernization vine, where we explore the general motivation of Cipó community epiphany transformations - modernity; family and community exchange vine, which describes the scheme that holds the permanence of the play; masculinity vine, explains the strong gender system that crosses Cipó community epiphany; reinvented tradition vine, where we locate the uniqueness of Cipó community epiphany tradition and its dialogues with modern dynamism; conflict between generation vine, depicts the differences between generations and how they contribute to the dialogue between the traditional and the new; theatrical spectacle vine, describes the play as a performative activity. Thus, we build a social scheme that analyzes the play of Kings of Cipó community as a whole, where change and continuity plan a cultural plot on their own

Análise jurídico-constitucional do fomento aos campos maduros de produção de petróleo no Brasil

The oil activities in Brazil had been started in an intensive way in the end of the 30 s and in the beginning of the 40 s. Many of the brazilians fields discovered in the past are nowadays in decline. They are called ―mature fields‖. These fields, because of the decline situation that characterizes them, are not interesting for the majors. The majors want the big fields and big productions. On the other hand, they could be interesting for the small and medium enterprises. The mature oil fields are instruments of development, they have oil and the oil production is an activity connected with many social and economics benefits: jobs, taxes, royalties, etc. The Brazilian State, in this context, needs to realize actions to promote the activities in the mature oil fields, especially with the work of the small and mediums enterprises. Many of the onshore brazilian mature fields are located at the Northeast, a region matched by many social and economic problems. The activities in the mature fields of the Northeast Region could solve some of its problems. The present research analyses the mature oil fields and its situations in Brazil, making criticisms and suggestions. The methodology adopted is theoretical and descriptive, with literature review, case law and legislation (Constituição Federal de 1988, ―Law of the Oil‖). This research examines the following points: mature fields rounds and its documents, name and definition of the mature fields, definition of small and medium enterprises, environmental aspects, concentration of certain activities of the sector and the royalties

Biodigestão anaeróbia dos dejetos de cabritos Saanen alimentados com dietas com diferentes proporções volumoso e concentrado

Avaliaram-se os efeitos da idade do animal e da proporção de volumoso nas dietas sobre a biodigestão anaeróbia dos dejetos de cabritos Saanen. Foram utilizadas as fezes produzidas por cabritos Saanen aos 90, 120 e 150 dias de idade e alimentados com dietas de três relações volumoso:concentrado (80:20, 60:40 e 40:60), representando as dietas 1, 2 e 3, respectivamente. Utilizaram-se biodigestores tipo batelada de bancada com capacidade para 12 litros de substrato em fermentação e 8% de sólidos totais iniciais para determinação das produções e dos potenciais de produção de biogás e metano, da redução de sólidos voláteis e quantificação dos teores de minerais no afluente e efluente. As maiores reduções de sólidos voláteis foram observadas nos substratos preparados com as fezes de cabritos aos 150 dias alimentados com a dieta com relação volumoso:concentrado de 40:60. Os melhores rendimentos de substrato ou fezes foram obtidos com os dejetos dos cabritos de 120 e 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. As maiores concentrações de minerais nos biodigestores foram observadas para as fezes de cabritos de 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. A biodigestão anaeróbia é eficiente na remoção de coliformes nos dejetos de caprinos, proporcionando efluentes com no máximo 4,3 × 10² coliformes totais termotolerantes por grama de material.

Produtividade de tomate tipo cereja cultivado em ambiente protegido e em diferentes substratos

O experimento foi realizado em Jaboticabal-SP, sob ambiente protegido, objetivando avaliar quatro substratos (Rendimax-Estufa®, areia, solo coberto com filme de polietileno preto e solo descoberto) e quatro híbridos de tomateiro tipo cereja ('Mascot', 'Gisela', 'Cheri' e 'Sweet Million'), sendo os substratos comercial e areia acondicionados em sacos plásticos. O delineamento experimental foi em blocos casualizados, em esquema fatorial 4 x 4, com quatro repetições. Utilizou-se irrigação por gotejamento, sendo a dotação hídrica realizada em função dos dados obtidos em um tanque Classe A. A solução nutritiva utilizada foi a recomendada por Castellane & Araújo (1995) para a cultura do tomateiro. Os frutos foram colhidos semanalmente, durante o período de 24/11/2000 a 24/01/2001, sendo avaliados o número e produtividade diária de frutos. Os cultivos em solo proporcionaram maior produção diária que no substrato comercial e em areia, para os híbridos Gisele e 'Mascot'. O híbrido 'Gisela' mostrou-se mais produtivo nos cultivos em solo, enquanto o híbrido 'Cheri', embora tenha proporcionado menores produções em peso, produziu maior número de frutos por planta. A produtividade dos tratamentos mais produtivos foi satisfatória, estando de acordo com os padrões de produção para a cultura no Brasil.

Ideal Mariano e docência: a identidade feminina da Proposta Educativa Marista

In the teaching history course it s found the female teacher entering, reflecting significantly in the continuous process of her identity redefinitions and reconstruction. This entering brings, even in a silent and not explicit way, the confluence of gender identity to professional identity, in which are present the relations of the proper to female. In the mastership case, these relations are found imbricated in the teaching identity construction and in the translation of this profession as female, based in Virgin Mary, through Mariano ideal diffused by the catholic church. Therefore there is a lanck in educational historiography towards the register of female teachers presence, mainly in male religious institute, the reason of this study, in which we seek to investigate: how to explain that a female identity can give support to a highly male educational project? What relations can we establish between this female identity and the entering of female teachers in Maristas Province Schools of North Brazil? We performed a bibliographic research in Maristas Schools Libraries, of Marista historial, in Recife, of Pontificia Universidade Católica do Paraná (Catholic University), in Curitiba-PR. We searched for support in studies about pedagogy history, of Marista Institute, Catholic Church, Brasilian Education and of Women; Mariologic studies, the referring to Marista Educational Proposal, to feminization and to teaching identity; and feminist theology productions. The empirical research included 10 schools from referred province and Marista Schools from Lisbon Portugal. Through semi-estructured interviews, we interviewed pioneer female teachers, Marista former Brothers and Brothers from those schools, due to their presence and action within the study period and for the concern to save their memories about the theme. The study reveals the particularities of Mariano ideal as female model and teaching, and her presence in Marista Educational Proposal. This study, in a historical approach, aims to contribute to give visibility to the woman in history and teaching construction in Brazil, mainly in religious institutions from male origin

Produção e qualidade de folhas de amoreira em função da época do ano e de colheita

A quantidade e qualidade das folhas de amoreira (Morus alba L.) exercem influência marcante sobre o desenvolvimento do bicho-da-seda e são, por sua vez, influenciadas por fatores como a idade das folhas, época do ano e características genéticas dos cultivares. Avaliou-se a produção e a qualidade nutricional de folhas de cinco cultivares de amoreira em diferentes épocas do ano e de colheita, objetivando verificar sua adaptação na região de Jaboticabal (SP). As folhas dos cultivares 'Miura', 'Korin', 'Calabresa', 'FM86' e 'FM Shima-Miura' foram colhidas na primavera, verão e outono após 45, 60, 75 e 90 dias da poda (DAP) e avaliadas quanto à produção de folhas níveis de proteína bruta (PB) e fibra em detergente neutro (FDN). As melhores produções foram verificadas em 'FM Shima-Miura', principalmente aos 75 DAP na primavera e no verão e aos 90 DAP no outono. No verão, as colheitas efetuadas aos 60, 75 e 90 DAP resultaram em produções mais elevadas. As épocas de colheita que resultaram em maiores níveis de PB foram aos 45 e 60 DAP e em menores níveis de FDN aos 60 DAP, respectivamente. Foi possível conciliar altos níveis de PB, baixos níveis de FDN e relativamente alta produção de massa foliar somente na colheita efetuada aos 75 DAP.

A educação da mulher em Lima Barreto

Lima Barreto has built an educational conception of women in his fictional productions despite nuances inciting scholars to debate his writings and label him as misogynist and philogynist. Thus, the objective of this study is to comprehend, through signs present in his literary works, how women used to be educated in early twentieth century to accomplish the historical differences in gender relations. The main reason for this extract is the periodicity of his publications that started in 1900 by means of chronicles in newspapers and ended in 1922 after his death. For this, we identified codes and rules forged in the social processes to be assimilated by children through diverse institutions, aiming to incite the production of behaviors and social practices represented by the existence men and women in an ever changing society. Gender relations are analyzed within a society for their configuration concept by Nobert Elias (1970) as interdependence bonds among individuals. An investigative method proposed by Ginzburg (1989) was the most adequate to conduct the research on the work of Lima Barreto because it enables us to reconstruct the education concept for women. The dramas and novels analyzed point out the construction of categories such as women education, family, love and seduction revealing the engagement of Lima Barreto with the social problems of the period investigated. It was concluded that gender differentiation has come from family education which kept men and women in opposing sides giving them a marriage perspective that, after consummated, would bring frustration to women causing them to adopt confronting practices against domination strategies through celibacy or adultery. This research constitutes a reflection based on determined representations like justice, respect and duties that were the ideas defended by Lima Barreto in his writings, concerning both broader situations in social life and particular gender relations

A Construção social do conhecimento :a reorientação curricular via tema gerador na Escola Cabana em Belém/PA

Cette étude analyse l'expérience de réorientation curriculaire atravers le sujet générateur, vécue dans les écoles qui composent le système municipal d'éducation de Belém du Pará - École Cabana, en ayant comme locus de recherche l'École Municipale João Carlos Batista. Ce mouvement de réorientation curriculaire, qui rompt avec le modèle traditionnel d'un curriculum linéaire, hiérarchique et fragmenté a comme préssuposées théoriquesméthodologiques les principes et les catégories freireanas la pédagogie critique qui estime un curriculum interdisciplinaire, dialogique, démocratique et contextuel, à partir de la systématisation d'une proposition theorico-méthodologique de réorientation curriculaire par le thème générateur, c'est-à-dire, en partant de situations-problème de la communauté scolaire, en faisant des relations négociées par les connaissances scolaires pour la compréhension et possible intervention dans la réalité. Cette proposition est mise en oeuvre non seulement à Belém, mais aussi par d autres municipalités du Brésil. Étant donné que l'École Cabana est une expérience inovatrice dans la tentative de viabiliser une Éducation vraiment démocratique, elle dialogue encore avec autres expériences d'écoles de même nature au Brésil, (comme l'École Plural-MG, l'École Citoyen - RS et l'École Candanga DF). Á partir des idées de Paulo Freire, J. Sacristán, M. Apple, C. Linhares, A. Coulon et autres j apporte des réflexions epistemologiques concernant le problème de la recherche qui consiste sur le registre et l'analyse de la tentative de construction sociale de la connaissance par le thème générateur qui a eu lieu à l'École Cabana dans la période de 2001 à 2004. Comme procédure méthodologique, j'ai développé une Recherche qualitative, de caractère collaboratif, en utilisant comme techniques de rassemble de données l observation participative dans le quotidien écolier, des interviews semi-structurées, et l'analyse des documents et des productions de l'École. Les résultats indiquent l'importance du registre de ce type d expérience, en soulignant leurs avances et reculs qui pourront servir de référentiel pour de futures politiques de réorientation curriculaire dans la direction de la construction sociale de la connaissance et, par conséquent, d'une Éducation plus démocratique et tournée vers une citoyenneté active

Adrien-Marie Legendre (1752-1833) e suas obras em Teoria dos Números

The present thesis is an analysis of Adrien-Marie Legendre s works on Number Theory, with a certain emphasis on his 1830 edition of Theory of Numbers. The role played by these works in their historical context and their influence on the development of Number Theory was investigated. A biographic study of Legendre (1752-1833) was undertaken, in which both his personal relations and his scientific productions were related to certain historical elements of the development of both his homeland, France, and the sciences in general, during the 18th and 19th centuries This study revealed notable characteristics of his personality, as well as his attitudes toward his mathematical contemporaries, especially with regard to his seemingly incessant quarrels with Gauss about the priority of various of their scientific discoveries. This is followed by a systematic study of Lagrange s work on Number Theory, including a comparative reading of certain topics, especially that of his renowned law of quadratic reciprocity, with texts of some of his contemporaries. In this way, the dynamics of the evolution of his thought in relation to his semantics, the organization of his demonstrations and his number theoretical discoveries was delimited. Finally, the impact of Legendre s work on Number Theory on the French mathematical community of the time was investigated. This investigation revealed that he not only made substantial contributions to this branch of Mathematics, but also inspired other mathematicians to advance this science even further. This indeed is a fitting legacy for his Theory of Numbers, the first modern text on Higher Arithmetic, on which he labored half his life, producing various editions. Nevertheless, Legendre also received many posthumous honors, including having his name perpetuated on the Trocadéro face of the Eiffel Tower, which contains a list of 72 eminent scientists, and having a street and an alley in Paris named after him

O professor e sua formação linguística: uma interlocução teoria-prática

The work in screen constitutes a study of entitled doutoramento THE teacher and your linguistic formation: a dialogue teoria-prática. In him, the researcher, discoursing on subjects that involve the teaching-learning of the verbal language, it focalizes the importance of the linguistic formation for professionals that act in the years you begin of the Fundamental Education. In that perspective, lens to analyze the interrelações among them you know about the teachers, referring to the language (verbal), mobilized in the process teaching-learning of the production of texts written by the students, enrolled in the years you begin of the fundamental teaching. For so much, it developed a research Colaborativa, of qualitative nature, with four partícipes, being three of them teachers of the empiric field, EETB (pointed school for the " Prova Brasil " (2005) as among the ten Brazilian schools with the worst index of revenue discente in the abilities to read, to write and to interpret) and the other (researcher) educational of UERN. The research made use of several methodological procedures, among which stand out: questionnaire, glimpses, reflexive sessions and cycles of reflexive studies, among others. These specific of the Methodology of the Elaboration Conceptual Ferreiriana, adopted in the process of (re)elaboration, for the partícipes of the language concepts, text, textual gender, spoken language and written language. With relationship to the analytic procedures, those were based in contributions of the theory of the formation of concepts, of the Applied Linguistics and of the archaeology of the elect concepts. The results appear that the process of linguistic formation, established through the research colaborativa and of the methodology of the elaboration conceptual ferreiriana, uniting knowledge of the areas of the Education and of the Language, it was productive and he/she reveals a narrow relationship among the acquired knowledge for the partícipes, the (re)organization of the process teachinglearning of the language and the improvement of the productions written by the students of those educational ones

Reconceitualização das categorias de skemp de compreensão relacional e compreensão instrumental como critérios globais

The thesis presents a systematic description about the meaning, as Skemp, relational understanding and understanding instrumental, in the context of mathematics learning, being that we had as a guide his understanding of the schema. Especially, we analyze some academic productions, in the area of Mathematics Education, who used the categories of understanding relational and instrumental understanding how evaluative instrument and we see that in most cases the analysis is punctual. Being so, whereas the inherent understanding relational schema has a network of connected ideas and non-insulated, we investigated if the global analysis, where it is the understanding of the diversity of contributory concepts for formation of the concept to be learned, is more appropriate than the punctual, where does the understanding of concepts so isolated. For this, we apply a teaching module, having as main content the Quaternos Pythagoreans using History of Mathematics and the work of Bahier (1916). With the data we obtained the teaching module to use the global analysis and the punctual analysis, using research methodology the Case Study, and consequently we conduct our inferences about the levels of understanding of the subject which has made it possible for us to investigate the ownership of global analysis at the expense of punctual analysis. On the opportunity, we prove the thesis that we espouse in the course of the study and, in addition, we highlight as a contribution of our research evidence of need for a teaching of mathematics that entices the relational understanding and that evaluation should be global, being necessary to consider the notion of schema and therefore know the schematic diagram of the concept that will be evaluated
