Robinson Crusoé e Macunaíma: racionalidade e ética - parte II

Este trabalho tem como objeto o estudo do conceito de eficiência econômica e procura mostrar que tal conceito pressupõe algumas hipóteses de natureza normativa. Recuperando uma metáfora literária construída na primeira parte desta pesquisa, procura-se estabelecer uma relação entre instituições, valores, ação racional e eficiência alocativa, partindo-se de uma análise do papel dos incentivos e dos sentimentos morais sobre a ação humana.

Relações interorganizacionais e eficiência coletiva: um estudo de caso no arranjo produtivo local de confecções do agreste pernambucano

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

Sobre (vivência) e mortalidade de pequenos negócios: o caso de mercados varejistas potiguares

This paper‟s starting point was the objective of understanding the relation between the reasons pointed out by small businesses owners for the continuity or shutdown of their businesses, and the reasons presented by the Environmental Theories. The paper discusses the Environmental Theories understand that it is supported by a systemic metaphor speech, discussing the theme in terms of organizational survival and mortality . The text reviews the literature showing the changes in the administrative thinking regarding the organization versus environment relation, and presenting general ideas about the micro and small businesses. In methodological terms, the qualitative approach was used in the research. Regarding the data collection technique, an in-depth thematic interview was used. It was carried out considering the elements of the techniques of life history and oral history, always giving priority to real world related narratives told by the interviewed subjects. The empirical corpus of the research was made up of seven owners of small retail businesses in two Potiguar cities: Natal and Mossoró. The interpretative and analytical process focused, at first, on the reflexive dialogue with each one of the owners‟ professional life history and business management experience, constituting the first level of analysis: reflections on individual narratives; and, afterwards, the interpretative process was developed through the analysis of all the subjects‟ statements, identifying the recurring themes and constituting the second level of analysis: reflection on the totalizing narrative. The themes identified in the totalizing narrative, that refer to the continuity of the businesses are: evolution, control, fidelity, liking what one does for a living. The themes that came up as reasons for shutdown are: lack of empathy with the business, lack of evolution, competition problems, suppliers and the government. The text synthesizes its comprehensions affirming that the reasons associated with continuity and shutdown of small markets, for this group of owners specifically, come up as a permanent tension between the volunteerism (quite human) and the determinism (systemic). The tension is shown in testimonies that at the same time evoke the organicist systemic logic through the themes evolution/no evolution, and also counterpoints with themes related to the interested human action, based on desires, feelings and personal convictions such as: liking what one does/ lack of empathy. As for the reflexive dialogue between the postulates of the Environmental Theories and the narratives, the results make it possible to affirm that, differently from the tension expressed by the subjects while talking about their reasons, the reasons associated with survival and mortality of businesses according to the Environmental Theories are theoretically polarized, seeming to preach options that are stagnated and shaping towards the subjects involved in the organization-environment relation

Educação ambiental: um estudo de experiências nas escolas municipais de Natal

This a research on pedagogical experiences about Environmental Education carried out in selected schools of the municipal education net of the city of Natal, Rio Grande do Norte State. This study occurs in a where social and environmental problems reach great dimensions and provoke discussions all over the planet. Inside this social context where education is taken as a form intervention in the world, several methodological and theoretical approaches emerge indicating Environmental Education tendencies as different ways to face challenges due to environmental crisis. The maim question pursued by the research is to inquiry how schools have developed their Environmental Education experiences. Pedagogical experiences on Environmental Education are analyzed in selected schools having as theoretical framework ideas for social change, by human action accordingly to Hanna Arendt‟s thought, and Marx‟s idea of praxis, (1989). The objective is to identify, to know and to map the pedagogical experiences on Environmental Education carried out in selected schools of the municipality teaching net having sociological cartography as a methodological strategy for analyzing empirical data. The results of the research pointed out existing reductionist and behaviorist-pedagogical perspectives as for as Environmental Education is concerned as well as environmental understanding, showing a predominance of the conservative Environmental Education tendency inside schools

Qualidade da água de nascentes com diferentes usos do solo na bacia hidrográfica do córrego rico, São Paulo, Brasil

Com o objetivo de verificar a influência de remanescentes de vegetação ciliar e da ação antrópica na qualidade da água, estudaram-se quatro nascentes, sendo duas com a presença de vegetação natural remanescente e duas com predominância de atividades agrícolas. Essas nascentes fazem parte da bacia hidrográfica do Córrego Rico, estando localizadas nos municípios de Taquaritinga e de Guariba - SP, em duas classes de solo: Argissolo e Latossolo, respectivamente. Definiram-se pontos de coleta da água nas nascentes e ao longo dos cursos d'água (entre 0 a 50 m da nascente), em dois períodos (chuvoso e seco). Foram analisadas as seguintes variáveis: cor, pH, temperatura, turbidez, alcalinidade, dureza total, dureza em magnésio, dureza em cálcio, fósforo, nitrogênio e demanda bioquímica de oxigênio. de maneira geral, ocorreu agrupamento por nascentes e também por períodos, confirmando que os períodos de amostragem, assim como as características e diferentes usos do solo influenciam na qualidade da água das microbacias. As variáveis cor, turbidez, alcalinidade e nitrogênio total foram as que apresentaram maior importância relativa nas variáveis canônicas.

Formatividade e interpretação: a filosofia estética de Luigi Pareyson

The concept of formativity, coined by Luigi Pareyson, is a key to the development of countless contemporary aesthetic studies. The aim of this dissertation is to present a deep understanding of the notion of Formativity and Interpretation, as evidenciated by the title Formativity and Interpretation: the aesthetical philosophy of Luigi Pareyson. The work Aesthetics - Theory of Formativity, first published in 1954, is considered a mark in the rebirth of aesthetics. In this dissertation, the concept of Formativity is examined as a component applicable to every human action, and not limited to pre-determined practices, nor referred to the application of preexisting. I ve performed an investigation of the triple concept of doing-inventing-interpreting, which simultaneously grounds Formativity. In the first section, Pareyson s Aesthetical Propaedeutic is presented; in the second, the Theory of Formativity: the aesthetical character of the whole human experience is analysed; and in the third chapter, The Aesthetical of Form and the Metaphysics of Figuration is related to the formativity character of the knowledge. Through this analysis, I ve intended to evidence how human operability can be understood as search and trial, figuration and invention, in the search for success. In this sense, this thesis seeks to present an interpretation of the idea of work-form, speculating the inexorability of invention and interpretation in an attempt to establish a new bottom line for the studies Pareyson s Aesthetics in Brazil

Estratégia de vida do peixe anual Hypsolebias antenori (Cyprinodontiformes: Rivulidae) do semiárido brasileiro

This work deals with the life strategy of an endangered annual fish, Hypsolebias antenori (Cyprinodontiformes: Rivulidae), of the Brazilian semiarid region. The eggs of these fish hatch at the onset of the rainy season, grows rapidly and they reproduce during the rainy season. When the water puddles dry out, the entire population dies. The resistant eggs which are buried in the bottom of the dried pools go through diapause stages, during which time the embryonic development becomes temporarily arrested. With the onset of the next rainy season, the eggs hatch and a new generation is formed. Specimens of H. antenori were captured during 2011 and 2013, in temporary water pools located in the hydrographic basin of river Jaguaribe in Ceará, Brazil. Sex ratio, the length-weight relationship, the growth type, first sexual maturity, anatomy and histology of the digestive tract, development of gonads, reproductive strategy, karyotypic pattern of the species, and the conservation status of H. antenori were investigated. The results of this study are presented in the form of eight articles. The first article is about the fish faunal composition of the hydrographic basins of Rio Grande do Norte, Brazil, wherein the record of H. antenori is included. The second article deals with the sex ratio, secondary sexual characteristics of males, the length-weight relationship and the type of growth. Males show a pattern of intense coloration with well developed fins. The sex ratio showed a significant predominance of females (1M:1.7 F). Males were larger in length and weight. The equation of weight and total length relationship was Wt=0.0271Lt3,8937, showing a positively allometric growth, indicating greater increase in weight than in length. The third article discusses the anatomy and histology of the digestive tract of H. antenori. It is considered as a generalist feeder with characteristics of omnivore, which utilizes different food sources. The fourth article discusses the stages and phases of gonad development and type of spawning of H. antenori. The fifth article is about the r reproductive strategy adopted by H. antenori which helps in successful reproduction over a short period of life. The sixth article deals karyotypic pattern of the species, constituting the first cytogenetic contribution to the genus. The seventh article discusses about the risk of extinction of this species which suffers a series of threats, such as, habitat loss through land use, deforestation, construction of reservoirs, pollution due to domestic and industrial sewage, besides pesticides and agrochemicals. Furthermore, decreasing rainfall and intensification of aridity due to global climate changes, interferes with the reproductive cycle. The eighth article deals with aggressive behavior adopted between males and among females during reproduction. All temporary water pools sampled during this study were in high degree of degradation, mainly due to human action. There is a great need for conservation measures to protect the populations of annual fish, including the creation of protected areas in the semiarid ephemeral aquatic environments of Brazil

Síntese, caracterização e aplicação de MCM-41 funcionalizado com diisopropilamina no processo de adsorção do dióxido de carbono

Emissions of CO2 in the atmosphere have increased successively by various mechanisms caused by human action, especially as fossil fuel combustion and industrial chemical processes. This leads to the increase in average temperature in the atmosphere, which we call global warming. The search for new technologies to minimize environmental impacts arising from this phenomenon has been investigated. The capture of CO2 is one of the alternatives that can help reduce emis ions of greenhouse gases. The CO2 can be captured through the process of selective adsorption using adsorbents for this purpose. Were synthesized by hydrothermal method, materials of the type MCM-41 and Al-MCM-41 in the molar ratio Si / Al equal to 50. The synthesis of gels were prepared from a source of silicon, sodium, water and aluminum in the case of Al-MCM-41. The period of synthesis of the materials was 5 days in autoclave at 100°C. After that time materials were filtered, washed and dried in greenhouse at 100 º C for 4 hours and then calcined at 450 º C. Then the calcined material was functionalized with the Di-isopropylamine (DIPA) by the method of wet impregnation. We used 0.5 g of material mesopores to 3.5 mL of DIPA. The materials were functionalized in a closed container for 24 hours, and after this period were dried at brackground temperature for 2 hours. Were subsequently subjected to heat treatment at 250°C for 1 hour. These materials were used for the adsorption of CO2 and were characterized by XRD, FT-IR, BET / BJH, SEM, EDX and TG / DTG. Tests of adsorption of CO2 was carried out under the following conditions: 100 mg of adsorbent, temperature of 75°C under flow of 100 mL/min of CO2 for 2 hours. The desorption of CO2 was carried out by thermogravimetry from ambient temperature to 900ºC under flow of 25 mL min of He and a ratio of 10ºC/min. The difratogramas X-ray for the synthesized samples showed the characteristic peaks of MCM-41, showing that the structure of it was obtained. For samples functionalized there was a decrease of the intensities of these peaks, with a consequent reduction in the structural ordering of the material. However, the structure was preserved mesopores. The adsorption tests showed that the functionalized MCM-41 is presented as a material promising adsorbent, for CO2 capture, with a loss of mass on the desorption CO2 of 7,52%, while that in Al-MCM- 41 functionalized showed no such loss

Os sentidos de compreensão nas teorias de Weber e Habermas

Partindo do pressuposto de que a teoria social elaborada por Habermas em muito se assemelha àquela construída por M. Weber, procedeu-se a um estudo comparativo com a intenção de identificar as formas pelas quais Weber e Habermas elaboraram o conceito de compreensão, ao mesmo tempo em que e o elegeram, cada um a seu modo, como instrumento metodológico adequado às dificuldades da produção de conhecimento científico nas Ciências Sociais. Tanto para Weber, como para Habermas, o conhecimento nas Ciências Sociais não consegue escapar das influências diretas da subjetividade do cientista, como também não é capaz de se proteger das contingências histórico-culturais aos quais inevitavelmente toda ação humana está vinculada. Por isso, fundamentados em suas próprias razões, tanto Weber quanto Habermas apontam a compreensão como a forma possível de conhecimento, o que implica a renúncia às pretensões explicativas e à produção de teorias gerais de fundamentação última, que são típicas das ciências convencionais.

Participação social e designação de espécie-bandeira: ações complementares à conservação de um parque estadual em área urbana

Facing environmental problems the planet appears several alternative preventive and control on behalf of the equation between development and environmental protection. One of the alternatives implemented in Brazil to conservation of biodiversity was the creation of protected natural areas regulated by the National System of Conservation Units (SNUC). This is an integrated study of the Comunication / Environmental Conservation, which prioritizes social participation as a complementary in the conservation process, the particular case of the Dunas do Natal State Park, the first conservation area in Rio Grande do Norte, for full protection. It takes into account the roles environmental, scientific and Park, which harbors a unique biodiversity, including endemic species and the fact being located in an urban area. It proposes the use of two complementary instruments, such as strategies for conservation. Considering the various individual experiences, it was analyzed the perception that the community is directly related to the Park. From this promoted the democratization of information about the park, its biodiversity and conservation. As another conservation tool, it was suggested the use of a flagship species for the park, or a body chosen symbol for environmental or social reasons, in order to protect and conserve certain natural environments, from the understanding and co -community participation. In this case, as proposed flag Coleodactylus natalensis species, the lizard-the-litter, to be endemic remnants of Atlantic Forest Park as having the type locality, be one of the smallest species of the world, South America's lowest-dependent shadow of the forest, sensitive to human action and therefore very vulnerable. This suggestion finds support in the degree of public acceptance that interacts directly with the Park, as a result of the evaluation of their perceptions. It was further observed in this study that this symbology to be used in order to promote the democratization of the Park and its biodiversity has an identification result, curiosity and probable involvement of the population with the issues of the Park

Educação ambiental e educação em valores em livros didáticos de ciências naturais

Os valores têm sido considerados importante conteúdo de ensino, sobretudo ao tratarmos de certas temáticas, como a ambiental. Procurando analisar o tratamento dado à dimensão valorativa da temática ambiental em três coleções de Ciências Naturais voltadas às séries finais do Ensino Fundamental verificamos a predominância da visão antropocêntrica, sendo a natureza valorizada em função de sua utilidade para o ser humano. O predomínio da valorização do conhecimento científico em detrimento de outras formas de conhecimento, da ação humana individual em detrimento da coletiva e a simples apresentação de leis ambientais foram outros aspectos problemáticos encontrados. Uma das coleções, entretanto, além de valorizar o trabalho coletivo dos alunos, também se destacou pela maior ênfase dada à dimensão estética, implicando uma visão de mundo menos utilitarista e um tratamento mais adequado do conteúdo valorativo da temática ambiental.

Riqueza de espécies de morcegos (Mammalia, Chiroptera) em dois diferentes habitats, na região centro-sul do Paraná, sul do Brasil

Estudo preliminar sobre a riqueza de espécies e a freqüência de capturas de morcegos em dois habitats, mata primária e reflorestamento de Araucária, na Região Centro Leste do Paraná. Foi empregado o mesmo esforço para as duas áreas, resultando na captura de 11 espécies na área de mata primária, contra oito no reflorestamento de Araucária. A uniformidade na distribuição da abundância -equitabilidade - foi maior na mata primária. No reflorestamento de Araucária, noventa por cento dos indivíduos coletados pertenciam somente a duas espécies. Pelos resultados, conclui-se que a floresta primária com numerosos nichos, apresenta uma riqueza de espécies elevada, mas a ação do homem reduz a riqueza de espécies geral, o que se reflete principalmente na dominância de poucas espécies. Destaca-se aqui, nos dois tipos de ambientes, a presença de Myotis ruber, listada como ameaçada de extinção no Brasil.

Processo grupal e a questão do poder em Martín-Baró

O presente artigo trata da concepção de processo grupal e poder social enfocada por Martín-Baró.¹ O autor retoma a concepção de grupo presente no trabalho de Sílvia Lane, quando considera os aspectos pessoais, as características grupais, a vivência subjetiva e realidade objetiva e o caráter histórico do grupo. Na perspectiva da psicologia social, segundo o autor, é muito mais relevante a análise do papel do poder na vida cotidiana, no dia-a-dia das pessoas, do que se centrar nos acontecimentos excepcionais e não rotineiros. Considerando que grande parte da prática profissional do psicólogo, principalmente numa perspectiva psicossocial, envolve o trabalho com grupos, a abordagem da questão do poder passa a ter papel fundamental. Neste sentido, o contato com a produção de Martín-Baró é essencial e pode contribuir incisivamente no nosso trabalho cotidiano.
