As várias teorias acerca da estrutura de capital despertam interesse motivando diversos estudos sobre o assunto sem, no entanto, ter um consenso. Outro tema aparentemente pouco explorado refere-se ao ciclo de vida das empresas e como ele pode influenciar a estrutura de capital. Este estudo teve como objetivo verificar quais determinantes possuem maior relevância no endividamento das empresas e se estes determinantes alteram-se dependendo do ciclo de vida da empresa apoiada pelas teorias Trade Off, Pecking Order e Teoria da Agência. Para alcançar o objetivo deste trabalho foi utilizado análise em painel de efeito fixo sendo a amostra composta por empresas brasileiras de capital aberto, com dados secundários disponíveis na Economática® no período de 2005 a 2013, utilizando-se os setores da BM&FBOVESPA. Como resultado principal destaca-se o mesmo comportamento entre a amostra geral, alto e baixo crescimento pelo endividamento contábil para o determinante Lucratividade apresentando uma relação negativa, e para os determinantes Oportunidade de Crescimento e Tamanho, estes com uma relação positiva. Para os grupos de alto e baixo crescimento alguns determinantes apresentaram resultados diferentes, como a singularidade que resultou significância nestes dois grupos, sendo positiva no baixo crescimento e negativa no alto crescimento, para o valor colateral dos ativos e benefício fiscal não dívida apresentaram significância apenas no grupo de baixo crescimento. Para o endividamento a valor de mercado foi observado significância para o Benefício fiscal não dívida e Singularidade. Este resultado reforça o argumento de que o ciclo de vida influência a estrutura de capital

La historia de la expansión colonial en los sertónes del Seridó del siglo XVIII y el asentamiento de los primeros pobladores alrededor de las haciendas de ganado y más tarde de la cultura de algodón, oculto la presencia afrodescendiente que ya regia esa vasta región. Por otro lado, la esclavitud se observaba como un fenómeno de segunda prioridad y leve, por el hecho de tener un número de esclavos muy reducido en relación al litoral azucarero; sin embargo no se puede minimizar las marcas que dejaron más de tres siglos de dominación colonial, pues la violencia simbólica en su descripción aun existe. Este trabajo tiene como objetivo reflexionar sobre las causas y consecuencias de la extinción precoz de la presencia afro-brasileña y de la invisibilidad de los núcleos familiares en el municipio de Acari. A través de las memorias de las familias Nunes, Inácio y Pereira, antiguos moradores del Saco de los Pereira y de las familias Pedros, Paula, Higinos y Félix outroras moradores de las haciendas de la región, pretendemos reflexionar sobre las actividades de sobrevivencia, las relaciones de trabajo, la propiedad de la tierra y los robos ocurridos en los siglos XIX – XX, así como mostrar la importancia de las tradiciones familiares en la elaboración de los discursos sobre el pasado y de las variadas identidades. La metodología utilizada durante la investigación, mantuvo como foco las entrevistas que contemplan historias de la vida y las memorias de nuestros interlocutores, en particular los afrodescendientes. Los relatos colocan una luz sobre las vivencias en el período algodonero, los oficios realizados en las haciendas (vaquero, bordado, culinaria, losa) donde se muestra la importancia de las familias negras para entender el escenario Acarienses. También fotos y documentos cartoriáles que ayudaron a componer las historias de vida. El estudio revela la presencia de muchas familias negras vinculadas a las haciendas, demostrando que existe otra versión de la historia local, teniendo como protagonistas aquellos cuya memoria fue silenciada y quedando así marcados por el estigma de la esclavitud.

The internalization process of the Portuguese possession in Northern Captaincies - after the Dutch eviction and the development of activities related to livestock in the backlands (Sertão) – expanded the Portuguese territory in America. This process resulted in the advancement of Portuguese conquest over the region and conflicts involving agents of colonization and indigenous groups who inhabited that space, as well as conflicts of interest of captaincy’s major social groups and the defense policies of the Portuguese territory possession. Among the rivers which run through Rio Grande captaincy’s territory, the Açu was the one that aroused conquerors and colonizers of the back lands interest, making that spatiality an area where interest and power exercises converged and generated discord. This research aims to analyze the territorial process of Assu backlands, from the pioneers, conquerors and colonizers action over the space studied, during the event known as the War of the Barbarians in Assu, conflict that ensured the integration of the area the territory and the wishes of the Portuguese crown. Thus, it will be taken as objects of study social phenomena that characterized Assu’s riverside - at the turn of the 17th to the 18th century, in a cutout that extends from 1680 to 1720 - as an area of conflicts of interest, noticeable for analysis from period documents such as records of land grants concessions, correspondence between colonial and kingdom authorities, documents from the exercise of administration of Portuguese America and legislation.

The farm’s rural dwellings of creation from the Seridó Potiguar microregion, built in the nineteenth century, became a reference by its vernacular character, i.e. these buildings, besides having recognized relevance to the identity of the region, they are adapted to the conditions of the place in many aspects (economic, cultural, construction, physical, et.) and consist in protective spaces in relation to hostile characteristics of Seridó’s climate. Considering the above premise, the following question arises: What characteristics of the nineteenth century Seridó Potiguar’s cattle farms are crucial for them to be a protective space in relation to the semiarid climate? In order to answer the question, this research aim to identify which particularities of the Seridó’s farmhouses that contribute to adaptability in these buildings to semiarid climate, as protection environments; and contribute to the stock valuation of the architectural heritage concerned. Therefore, procedures were adopted divided into two stages. Were first identified the recurring characteristics in the studied buildings, through typological study performed from existing inventories (DINIZ, 2008; FEIJÓ, 2002; IPHAN, 2012). To define the type it worked up with the concept that merges Durand’s analytical typology that identifies the similarities and differences to classify buildings, having the character of historical survey and architectural documentation, with the definition proposed by Argan (1963) that the type is not defined a priory, but the deduction from a number of illustrative cases which have formal and functional similarity with each other. Then worked up in a sample of five different types with each other, defined by the possibility of access to the interior of the houses, proximity to other copies, good state of conservation and preservation. The contemplated farms were: Pitombeiras, Agenus e Garrotes in Acari’s town, and the municipality of Caicó, Palma and Penedo. The second stage consists of the architectural survey, photographic record, digital three-dimensional modeling (aiming to expand the existing documentation and registration) and thermal monitoring over approximately a representative day in five farmhouses, relating the thermal performance of the houses with their individual characteristics. The selected variables for analysis monitoring are based on the thermal comfort adaptive model (SPAGNOLO and DE DEAR, 2003 apud NEGREIROS, 2010). The characteristics of the houses were analyzed as meeting the passive thermal conditioning strategies recommended by NBR 15220 (ABNT, 2005), for the bioclimatic zone 7 where the municipalities of Caicó and Acari are located. The house’s analysis of the operating temperatures revealed that 90% of the times of day the environments are within the comfort range. The farmhouses, which had a higher degree of compliance with recommended bioclimatic strategies, had the best thermal performance. In environments (usually the kitchen and rooms with low ceiling heights, exposed to west radiation) which still had discomfort hours, the thermal comfort can be reached with air movement approximately 1,0 m/s.

Os ambientes aquáticos continentais da metade sul do RS são caracterizados por uma ampla planície costeira, onde destaca-se a Lagoa Mirim, com uma área total binacional (Brasil e Uruguai) de 3.750 Km². Nesta região, a pesca é uma importante atividade sócio-econômica, porém, a economia da região baseia-se no cultivo do arroz e na criação de gado. A proposta deste trabalho foi realizar um diagnóstico preliminar desta atividade na L. Mirim. A metodologia foi baseada na aplicação de formulários aos pescadores artesanais (perfil sócio-econômico e características da pesca) e na identificação das espécies que compunham a captura proveniente do desembarque pesqueiro no entorno da L. Mirim (Jaguarão, Santa Isabel e Santa Vitória do PalmarPorto e Curral Alto). Os dados de captura total de pescado foram provenientes de fontes independentes e complementares. O estudo sugere um perfil do pescador artesanal composto por 71% de indivíduos de sexo masculino, entre 20 e 65 anos de idade que costumam ficar de uma semana a quinze dias embarcados. A maioria (71%) dos pescadores artesanais entrevistados possui somente ensino fundamental e seus familiares geralmente estão envolvidos na atividade pesqueira. Foram identificados 28 locais de pesca e as principais espécies capturadas pela pesca artesanal foram: traíra Hoplias malabaricus, jundiá Rhandia aff. quelen, pintado Pimelodus maculatus, peixerei Odontesthes spp, viola-cascuda Loricariichthys anus e tambico Oligosarcus spp. A traíra foi a espécie mais representativa em peso (> 40%). Estas espécies apresentaram flutuações na composição das capturas ao longo do ano; os menores valores foram registrados entre julho e setembro (meses frios), exceto para o peixe-rei. A análise dos dados também aponta uma variação interanual dos valores totais de pescado e alguns fatores que podem estar associados à diminuição da captura são os prolongados períodos de seca na região, o uso da água na orizicultura e a falta de fiscalização da atividade pesqueira. Estudos baseados em estimativas de pescarias e conhecimento sobre a biologia das espécies capturadas podem fornecer subsídios para o correto manejo dos recursos pesqueiros, para tanto, são necessárias pesquisas que investiguem aspectos do uso sustentado das espécies de importância econômica na região e os possíveis efeitos da atividade pesqueira sobre a estrutura e a biodiversidade do ecossistema. Assim, para garantir a sustentabilidade da Lagoa Mirim, faz-se necessário envolver os pescadores artesanais e suas estratégias de pesca, em função de seus conhecimentos ecológicos, nas pesquisas que integram a elaboração das políticas públicas.

This work was general-purpose, develop a proposal of a theoretical model of decisionmaking with a focus on management of small family farms costs, which enables support for decision making. And the following objectives: i) develop a structured methodology, which allows to form a literary basis to provide scientific support for the implementation of research; ii) develop based on the literature the dimensions and variables of the necessary models to propose an application and iii tooling) to implement the proposed model within the dimensions and variables, and validate every stage background and perform the necessary conclusions to verify the effectiveness of applied model. In terms of methodology, we used a structured methodology, which allowed forming a bibliographic portfolio of 29 articles, and through the research constructs developed, based on an existing model, an activity segmentation model for aid farmer of small family farms in the decision-making process with emphasis on cost management. The model was applied in six family farms in the South West region of Parana and Santa Catarina West. With regard to the search results, it was identified that the model can be applied to the specific context for which it was created. It was also possible to identify that the proposed model was valid and relevant to aid in the management of family farms by identifying, through the targeting of productive activities, investment priorities guided by the balance between managing costs and return activities. Moreover, possible to target the activities of six surveyed properties, demonstrating that the property 02, has the shape of more complex segmentation should be divided into three groups of activities, which can be conducted in parallel without any restrictions between activities. Other properties have the segmentation of the simplest activities, allowing viewing in this way that there are activities of groups that require prioritizing investments. Specifically the property 01 and 04 have the highest priority investment target groups, the most prominent activities of groups representing respectively 49.32% and 47.40%, which are represented by grain production activities on the property 01 and grain production, beef cattle and eggs on the property 04.

As passagens em grelha são infra-estruturas largamente utilizadas para impedir a deslocação do gado, mas que permitem a circulação de viaturas. Porém, também resultam numa armadilha de fosso onde pequenos animais terrestres podem cair inadvertidamente. O principal objectivo deste estudo foi verificar o efeito que as passagens em grelha têm sobre as populações de anfíbios, aquando das suas deslocações sazonais. Estudaram-se 18 passagens em grelha localizadas em duas zonas de amostragem - Elvas e Alandroal - no Alto Alentejo (Portugal). Esta investigação revelou que a principal espécie encarcerada nestas infra-estruturas é o sapo-de-unha-negra (Pelobates cultripes). Em termos gerais, os anfíbios mais terrestres são significativamente (teste do x2) mais afectados do que os anfíbios marcadamente aquáticos. O teste de Mantel mostrou que não existe correlação entre o tipo de passagem em grelha e os anfíbios encontrados nessas infra-estruturas. Para mitigar o aprisionamento de anfíbios nas passagens em grelha, são propostas cinco medidas. ABSTRACT; Cattle grids are infrastructures widely used to avoid the movement of cattle along a road, though allowing the circulation of vehicles. However, they also result in a pit trap where small terrestrial animals may inadvertently fall. The main objective of this study was to check the effect that cattle grids have on amphibian populations, during their seasonal migrations. 18 cattle grids, located in two sampling zones - Elvas and Alandroal- in Alto Alentejo (Portugal), were studied. This investigation showed that the main species imprisoned in these devices is the iberian spadefoot toad (Pelobates cultripes). Generally, the more terrestrial amphibians are significantly (x2 test) more affected than markedly aquatic amphibians. Mantel test showed that there is no correlation between different kinds of cattle grids and the amphibians found in these infrastructures. To mitigate the imprisonment of amphibians in cattle grids, five measures are proposed.
