Social entrepreneurship practices and social change In Brazil: a qualitative study in three non-governmental organizations

Social Entrepreneurship (SE) has attracted growing interest from a wide variety of actors over the last 30 years, especially due to a general agreement that it could be an important tool for tackling many of the world’s social ills. In the academic sphere, this growing interest did not translate into a matured field of study. Quite the opposite, a quick look at this literature makes it evident that: SE has been consistently subjected to numerous theoretical discussions and disagreements, especially over the definition of the concept of SE which is often based on a taken-for-granted notion of social change; it has been more systematically investigated in restricted contexts, often leaving aside so called developing/emerging countries like Brazil and especially lacking in-depth qualitative studies; SE literature lags behind SE practices and few studies focus on how SE actually occurs in a daily and bottom-up manner. In order to address such gaps, this thesis examines how social entrepreneurship practices accomplish social change in the context of Brazil. In this investigation I conducted an inductive practice-based, qualitative/ethnographic study in three Non-Governmental Organizations (NGOs) located in different cities in the Brazilian state of São Paulo. Data collection lasted from February 2014 until March 2015 and was mainly done through participant observations and through in-depth unstructured conversations with research participants. Secondary data and documents were also collected whenever available. The participants of this study included a variety of the studied organizations’ stakeholders: two founders, volunteers, employees, donors and beneficiaries. Observation data was kept in fieldnotes, conversations were recorded whenever possible and were later transcribed. Data was analyzed through an iterative thematic analysis. Through this I identified eight recurrent themes in the data: (1) structure; (2) relationship with other organizational actors (sub-themes: relationship with state, relationship with businesses and relationship with other NGOs); (3) beliefs, spirituality and moral authority; (4) social position of participants, (5) stakeholders’ mobilization and participation; (6) feelings; (7) social purpose; and (8) social change. These findings were later discussed under the lens of practice theory, and in this discussion I argue and show that, in the context studied: (a) even though SE embraces a wide variety of different social purposes, they are intertwined with a common notion of social change based on a general understanding and aspiration for social equality; (b) this social change is accomplished in a processual and ongoing manner as stakeholders from antagonistic social groups felt compelled to and participated in SE practices. In answering the proposed research question the contributions of this thesis are: (i) the elaboration a working definition for SE based on its relationship with social change; (ii) providing in-depth empirical evidence which accounts for and explains this relationship; (iii) characterizing SE in the Brazilian context and reflecting upon its transferability to other contexts. This thesis also makes a methodological contribution, for it demonstrates how thematic analysis can be used in practice-based studies.

Paradigma constitucional brasileiro da livre concorrência e da defesa do consumidor face às estruturas de poder no mercado

The Federal Constitution of 1988, when taking care of the economical order, denotes special concern in the abuses of the economical power and the disloyal competition. The mark to mediate of all this is, in fact, the defense and the consumer's protection, once this is final addressee of whatever if it puts at the consumption market. The coming of the Law 8.078/90, Code of Protection and Defense of the Consumer, inaugurates a time of effective concern with the homogeneous individual interests originating from of the consumption relationships. In this point, the focus of main to face of the present work lives, in other words, the protection of the right to the individual property, especially manifests in the exercise of the trade freedom that keeps direct relationship with the respective social function the one that is destined. The code of the consumer's defense doesn't just take care of this, but also of the other star of the relationships of the consumption. When affirming in the interruption VI of the art. 4th that the national politics of those relationships, finds ballast in the prohibition and repression efficient of all of the abuses committed in the consumption relationships, keeping inherent relationship-causality in the economical order, sculpted for the article 170 in the Constitution of 1988. In the generic plan, the mark of the present work is to question concerning the limits of the trade freedom and previsible collisions with protection norms and the consumer's defense, as well as factual convergences of those small systems, especially in what he/she refers to the innate interests to the suppliers. In the specific plan, we aspirated to identify the protection device-commands to the actors of the trade relationship, capable to guarantee the free competition in a global economy of market, seeking especially the Well-being, for soon afterwards, in an analytical perspective, to discover the possible applications that it holds the Federal Constitution, in headquarters of economical freedoms. It was observed that the consumer today doesn't need only of laws that their needs, fruit of the vulnerability that it is him/her meditate innate. He/she lacks, yes, of effective mechanisms that prevent lesions that can be them impinged by the suppliers at the time in that you/they are useful to repair the damages when happened, punishing the author of the damage

A tutela constitucional da exploração de petróleo em águas internacionais em face do princípio do desenvolvimento sustentável: a possibilidade de responsabilização civil do dano futuro

The demands brought by a society doomed to the constant production of global risks, which whose effects are not immediately noticed effects are not perceived immediately, claim from the Law a new Theory about the Risk, that would offer a broad environmental protection, at the same time it would still be compatible with the idea of economic efficiency, required by the Modern Industry. The expansion of the methods and technologies regarding the exploitation and production of oil causes the constant expansion of the exploitable boundaries, especially in ultra-deep waters with the Pre-salt layer, in Brazil, or the still incipient research about the polymetallic nodules and other mineral sources in international waters, like the Atlântico Sudoeste, by the Programme on Ocean Science in Relation do Non Living Resources (OSNLR), a global study performed in partnership with the Intergovernmental Oceanographic Commission, from UNESCO (IOC UNESCO) and also with the Division of Ocean Affairs and Law of the Sea (UNDOALOS). Thus, we aim to analyze the correlation, and possible collisions between the right to a balanced environment and the free exercise of economic activity and the occurrence of environmental damages from the perspective of the exploitation activities of oil and other natural resources in international waters, specifically in the Area, from the constitutional principle of sustainable development and its legitimacy by the environmental international protection. Therefore, this study also aims to evaluate the legal framework for exploration and production of oil in international waters, particularly in the Area, and appraise how the constitutional instruments and mechanisms for environmental protection can impact on the international environmental protection system in order to ensure the present and future generations an ecologically balanced environment, laid down in Article 225 of the Brazilian Constitution, even with so many risks posed by the activities of exploitation and production of oil in international waters. In the meantime, we intend to also intend to investigate the possibility of future liability for environmental damage in order to ensure that constitutional principle and, consequently, and try to define the concept of environmental damage and its implications on the constitutional principle of environmental protection. Given all that was in summary, this work aims to contribute to the evolution of the new Theory of Environmental Risk, turning the law into something more than a punitive or corrective element in this society, but into a legal risk management, that may be triggered even before the consolidation of the damage

Eficácia da imunoterapia no tratamento de pitiose facial em equino

Background: Pythiosis in horses is a proliferative and ulcerative disease that primarily affects the skin and subcutaneous tissue of limbs, thoracic-abdominal region and head. This disease sometimes can also affect limb bones or cause tumoral masses in abdomen. Usually, the cutaneous cases are confused with habronemiasis. The disease is more common in marshy areas, places with formation of slow drainage ponds and aquatic vegetation under high temperatures. The aim of this study was to describe the development of facial lesions in a horse caused by pythiosis in Cuiaba, Mato Grosso, and, additionally to discuss relevant issues regarding the diagnosis, clinical course and response to immunotherapy treatment.Case: One five years old mare of unknown breed, created in property located in the Cerrado region, had a wound on its face difficult to be healed and non-responsive to several treatments based on ivermectin and organophosphate administrated by either topical or systemic via. The animal was assisted on the farm of origin by the veterinary team of the Clinical Medicine sector, of the Veterinary Hospital, Universidade Federal de Mato Grosso (HOVET-UFMT). on the occasion of the visit, which occurred 60 days after onset of signs, the animal showed a circular single large lesion, ulcerative with serous discharge on the right part of its face, between the eyes and nostrils. There were some necrotic foci with sinus, from which kunkers were extracted; a condition compatible with pythiosis. The diagnosis was confirmed by histology, ELISA and PCR.Discussion: Assuming pythiosis from data obtained from the survey and profile of the lesion (secretory aspect, emaciation and presence of sinus and kunkers), immunotherapy treatment was immediately applied. The advanced clinical aspects and the fact that early diagnosis and treatment are essentials to satisfactory therapeutic response were also taken into consideration for starting the treatment. The remission of signs was achieved after five subcutaneous applications with 14 days between each application. From the second application, it was observed clinical improvement and after 60 days of treatment there was almost complete remission of signs. The signs for a satisfactory response in the injury site followed the order of decreasing secretory aspect, decreasing borders, decrease the itching and bringing the edges together with the formation of a thin layer of crust on the surface. Pythiosis cases with lesions on the face and lower abdomen are commonly confused with habronemiasis by macroscopic and widespread similarity between technicians and attendants, and essential support to the diagnosis through laboratory tests, which in turn are still underutilized. In this case, the authors demonstrated the therapeutic efficacy of immunotherapy as an advantage, considering the possibility of applying it in cases of lesions in areas of difficult surgical access, treatment conditions in the field, with low cost and ease of application. Further studies approaching this alternative therapy are necessary, since side effects have been observed in some cases.

Effects of a non-rinse conditioner on the enamel of primary teeth

O objetivo deste estudo in vitro foi de avaliar ao microscópio eletrônico de varredura os aspectos morfológicos do esmalte de dentes decíduos após condicionamento com ácido fosfórico a 36% ou com um agente condicionador não lavável. Foram selecionados 10 dentes decíduos anteriores esfoliados naturalmente. As amostras sofreram limpeza coronária com pasta de pedra-pomes e água, em baixa-velocidade. O condicionamento foi realizado no esmalte da face vestibular. Os espécimes foram divididos em dois grupos: G1 (n=10): condicionamento com ácido fosfórico a 36% na forma de gel - Conditioner 36 (Dentsply) durante 20 segundos, seguidos de lavagem com água durante 15 segundos; G2 (n=10): condicionamento com NRC - Non Rinse Conditioner (Dentsply) durante 20 segundos, seguidos de secagem com ar durante 15 segundos. As amostras foram desidratadas, montadas em bases metálicas e cobertas com ouro para análise ao microscópio eletrônico de varredura (Jeol JSM 6.100). A análise da eletromicrografias revelou que ambos os agentes condicionadores foram efetivos para condicionar o esmalte de dentes decíduos, causando microporosidades mas com melhor resultado quando utilizou-se o ácido fosfórico a 36% na forma de gel.

The Yang-Lee zeros of the 1D Blume-Capel model on connected and non-connected rings

We carry out a numerical and analytic analysis of the Yang-Lee zeros of the ID Blume-Capel model with periodic boundary conditions and its generalization on Feynman diagrams for which we include sums over all connected and nonconnected rings for a given number of spins. In both cases, for a specific range of the parameters, the zeros originally on the unit circle are shown to depart from it as we increase the temperature beyond some limit. The curve of zeros can bifurcate- and become two disjoint arcs as in the 2D case. We also show that in the thermodynamic limit the zeros of both Blume-Capel models on the static (connected ring) and on the dynamical (Feynman diagrams) lattice tend to overlap. In the special case of the 1D Ising model on Feynman diagrams we can prove for arbitrary number of spins that the Yang-Lee zeros must be on the unit circle. The proof is based on a property of the zeros of Legendre polynomials.

Non-Ohmic and dielectric properties of a Ca2Cu2Ti4O12 polycrystalline system

An investigation was made into the non-Ohmic and dielectric properties of a Ca2Cu2Ti4O12 perovskite-type system. Compared to the traditional CaCu3Ti4O12-based composition, the imbalance between the Ca and Cu atoms caused the formation of a polycrystalline system presenting similar to 33.3 mol % of CaCu3Ti4O12 (traditional composition) and similar to 66.7 mol % of CaTiO3. As for non-Ohmic properties, the effect of this Ca and Cu atom imbalance was that a nonlinear electric behavior of similar to 1500 was obtained. This high nonlinear electrical behavior emerged in detriment to the ultrahigh dielectric property frequently reported. The high non-Ohmic property was explained by the existence of Schottky-type barriers, whose formation mechanism may be similar to that proposed for traditional metal oxide non-Ohmic devices, according to similarities discussed herein.

SEM analysis of the in situ early bacterial colonization on two novel feldspathic ceramics submitted to different types of glazing

Aim: The aim of this study was to evaluate in situ, the early bacterial colonization on feldspar-ceramics submitted to different glazing. Methods and Materials: Fourteen standardized disc specimens (diameter: 5 mm, thickness: 1.5 mm) of each of two micro-particulate feldspathic ceramics (VM7 and VM13, Vita) were produced according to manufacturers' specifications for a total of 28 specimens (24 for the analysis of biofilm and 4 for topographic analysis analyzing the ceramic surfaces). Specimens from each type of ceramic were submitted to two different glazing methods composing four groups: VM7 glazed using glazing liquid Vita Akzent® 25 (G1) and glaze firing (G2), VM13 glazed using glazing liquid (G3) and glaze firing (G4). Six individuals (n=6) wore oral appliances with four ceramic specimens, fixed on the buccal face of the appliances. After 8 hours, each sample was evaluated for the presence (1) or absence (0) of bacterial colonization under a scanning electron microscope (SEM) on five randomly selected fields. The value for each sample was cumulative of the results observed in the fields. One sample from each group was evaluated under a SEM to verify the topographic pattern. Results: There was no difference with regard to bacterial colonization between the feldspar-ceramics and between the glazing types (Kruskal-Wallis non-parametric test). Conclusion: Feldspar-ceramics submitted to firing or glaze firing with Vita Akzent® 25 present a similar condition for in situ bacterial colonization. The similar topographic pattern of the ceramic surfaces seems to have influenced the bacterial colonization.

Nilpotency of the b ghost in the non-minimal pure spinor formalism

The b ghost in the non-minimal pure spinor formalism is not a fundamental field. It is based on a complicated chain of operators and proving its nilpotency is nontrivial. Chandia proved this property in arXiv:1008.1778, but with an assumption on the nonminimal variables that is not valid in general. In this work, the b ghost is demonstrated to be nilpotent without this assumption. © 2013 SISSA, Trieste, Italy.

Influence of two different vinification procedures on the physicochemical and sensory properties of Brazilian non-Vitis vinifera red wines

The objective of this study was to evaluate the association between the physicochemical properties and sensory acceptance of Brazilian red wines by applying chemometric techniques. Therefore, three winemaking processes were carried out: a traditional winemaking process and two novel winemaking processes, pre-drying and static pomace. Significant differences could be identified amongst the physicochemical properties of the wines (P<0.001). The sensory results showed greater acceptance of the wines made after pre-drying of the grapes or from the static pomace, as compared to commercial brands. Cluster analysis and Multidimensional Scaling were successfully applied and their results demonstrated the influence of the total phenolic content and color indexes on acceptance of the appearance of the wines. The odor was associated with the alcohol content, acidity, dry extract, total and reducing sugars and the body of the wines. The flavor was associated with several physicochemical properties which influenced the overall acceptance of the samples. © 2013 Elsevier Ltd.

Um estudo sobre os ensaios jornalísticos de Franklin de Oliveira: a face das críticas rosianas

Este trabalho visa a discutir alguns aspectos da crítica literária produzida em larga escala nos jornais de meados do século XX, conhecida como crítica jornalística ou de rodapé, mais precisamente a contribuição crítica de Franklin de Oliveira (1916-2001) para as três primeiras publicações literárias do autor Guimarães Rosa (1908-1967), Sagarana (1946), Corpo de baile (1956) e Grande sertão: veredas (1956), verificando quais teorias e métodos eram usados por esse crítico para analisar um conjunto de obras que se mostrava, à primeira vista, como desafio aos atentos críticos da época. Franklin de Oliveira, mencionado por Benedito Nunes, em Rumos da crítica (2000), como injustamente esquecido nas referências das publicações acadêmicas, deixou um vastíssimo conjunto de ensaios humanísticos sobre música, literatura, política, entre outros, do Ocidente, esclarecendo a importância da arte e da literatura para a formação de um homem total, não alienado e consciente de sua humanidade. Os seus ensaios, de alta erudição, refletem a complexidade da obra rosiana sob o prisma filosófico, político e, principalmente, estético, pois tem o entendimento de que as situações externas à obra literária devem emergir no gênero literário considerando artisticamente o fato exposto. Por isso, para Franklin de Oliveira, Guimarães Rosa foi um escritor revolucionário, por ter realizado uma mímesis que não ficou presa ao seu tempo presente, e, por meio do elemento linguístico, literário e metafísico, conseguiu promover a “transcendentalização” da prosa literária brasileira. Assim, esta dissertação está estruturada em um panorama geral dos assuntos aqui apresentados e em três capítulos, quais sejam: “Por uma definição de crítica literária”, “Do intelectual ao crítico jornalista: Franklin de Oliveira, um humanista por excelência” e “Legado de Franklin de Oliveira à crítica rosiana: sob o foco da revolução rosiana”, a fim de alcançar o entendimento sobre a importância de se estudar as análises escritas em outra época a respeito das obras de um autor de literatura, como Guimarães Rosa, que ainda hoje são muito lidas e discutidas. Para tanto, um dos pressupostos teóricos para este estudo tem em vista o “experienciar dinâmico da obra literária por parte do leitor”, algo salientado pela Estética da recepção no livro A história da literatura como provocação a teoria literária (1994), de Hans Robert Jauss, este trabalho possibilita questionar ou legitimar a tradição de uma crítica por meio da tríade hermenêutica do compreender, interpretar e aplicar.

Caracterização microestrutural e de propriedades mecânicas de soldas do aço ASTM A 131 pelos processos FCAW convencional e com adição de arame frio

O trabalho aqui representado retrata de modo comparativo as características mecânicas e microestruturais de metais de solda empregando duas técnicas de soldagem uma já disseminada, FCAW (Soldagem a Arco Voltaico com Arame Tubular) e a outra é inovadora, FCAW-AF (Soldagem a Arco Voltaico com Arame Tubular com Adição de um Arame Frio não energizado) em três níveis de velocidades 6, 8 e 10 m/min. Sendo que este processo variou os diâmetros dos arames frio adicionados, entre 0.8 e 1.0 mm. O metal de base utilizado foi o aço naval ASTM 131 grau A (baixo carbono) em geometria de chapas de 150 mm x 300 mm x 9,5 mm, aplicadas em chanfro em V (Bisel de 22,5º) com ângulo somado de 45º, com leve abertura de raiz de 2,4 mm. A solda usada foi do tipo topo com a aplicação de dois passes, um passe de raiz e o passe de acabamento (ou enchimento). A fim averiguar as condições desses cordões de solda foram realizados 05 tipos de ensaios destrutivos, são eles: dobramento transversal de face, tração, tenacidade ao impacto (tipo Charpy com entalhe em V), microdureza e o ensaio metalográficos. Além das análises não destrutivas como o ensaio visual e o líquido penetrante. De maneira geral, os resultados para o processo FCAW-AF, mostraram-se compatíveis, em relação ao processo FCAW convencional, porém alguns resultados apresentaram valores de propriedades mecânicas menores. Este fato pode, muito provavelmente ter ocorrido pela presença de descontinuidade na junta pelo FCAW-AF. Quanto às caracterizações microestruturais, os resultados da junta FCAW-AF foram semelhantes os da FCAW convencional para todos os níveis estudados.

The dynamic implementation of non-overt arguments in nominalizations

Valency is an inherent property of nominalizations representing higher-order entities, and as such it should be included in their underlying representation. On the basis of this assumption, I postulate that cases of non-overt arguments, which are very common in Brazilian Portuguese and in many other languages of the world, should be considered a special type of valency realization. This paper aims to give empirical support to this postulate by showing that non-overt arguments are both semantically and pragmatically motivated. The semantic and pragmatic motivations for non-overt arguments may be accounted for by the dynamic implementation of the FDG model. I argue that the way valency is realized by means of non-overt arguments suggests a strong parallelism between nominalizations and other types of non-finite embedded constructions – like infinitival and participial ones. By providing empirical evidence for this parallelism I arrive at the conclusion that there are at least three kinds of non-finite embedded constructions, rather than only two, as suggested by Dik (1997).

Strategic planning for dairy cattle: SWOT analysis applied to a property of a farmers' association in Dracena, São Paulo state, Brazil

The sector of milk production in Brazil is very heterogeneous (high-tech in large scale X family properties). This study aimed to develop a diagnostic as a basis for a strategic plan to face the challenges inherent in operating a dairy farm in property of a farmers' association in Dracena, São Paulo, Brazil. It was observed that the association needs a more efficient guidance in the marketing, production and finance areas, not to compromise the search for new markets and continued growth in activity.
