Práticas Organizacionais e Estrutura de Relações no Campo do Desenvolvimento Metropolitano

The aim of this study is to examine the relationships between the organizations responsible for urban planning in the towns of the Metropolitan Region of Curitiba, Brazil, and how these relationships influence urban development practices. In the article we establish a definition of organizational practices in accordance with social practices and, empirically, we enquire how the urbanism model of the capital city of Paraná State impacts on the towns in the region. The theoretical frame of reference is characterized by the institutional theory in its structurationist approach. When describing the research strategy, we outline the relationships between the organizations of the towns of the Metropolitan Region of Curitiba through a social network analysis. Meanwhile, the urban development practices were identified based on secondary data and statements by 62 public managers. The results show a low density in direct relationships between town halls, with the network becoming more dense when State Government departments are involved. Despite the low level of direct influence of Curitiba’s urbanism on the other towns of the metropolitan region, characteristics of domination, signification and legitimization reveal some isomorphic practices and the presence of Brazilian cultural factors influencing the way public organizations act

Organizational Fields and the Structuration Perspective: Analytical Possibilities

The concept of the organizational field has been greatly dealt with in the literature on institutional theory in recent years. As the concept of field involves a relational and symbolic dimension, we propose that the theory of structuration, based on the logic of recursiveness between agency and structure should be adapted to theunderstanding of the field dynamically. In this way, the objective of this theoretical essay is to deal with the dynamic of the organizational field using structurationist logic, allowing that from this logic we recall both the importance of the practice in the structuration process of the organizational field and the historical and recursive character which may constrain or enable the actions of social actors. To this end, we revise the concept of field in different perspectives of analysis, reflecting on the implication of the theoretical presuppositions of each approach and then discuss in a critical manner the theoretical foundation of the structuration process of organizational fields based on the structurationist approach. We conclude the paper with propositions pertaining to the revision of the concept of field from a multiparadigmatic viewpoint in which structure and agency are recursively implied

A Questão da Agência em Redes Acadêmicas de Pesquisa : Centralidade, Produtividade e Escolha

No presente artigo, investigamos o papel da agência na construção do conhecimento científico com base em pressupostos do estruturacionismo. Para tanto, a noção de agência foi empiricamente tratada a partir da análise de redes sociais, tendo como indicadores a centralidade, produtividade e escolha preferencial de pesquisadores do campo da pesquisa na área dos estudos organizacionais e da estratégia em organizações no Brasil. Foram considerados 2.332 artigos entre os anos de 1997 e 2005, por meio dos quais analisamos 2.072 pesquisadores. Destacamos o papel de alguns deles, classificados como continuantes, para avaliar mais detalhadamente indicadores estruturais, além da trajetória de sua produção acadêmica. Nossos achados permitem afirmar que não somente a estrutura social apresenta dualidade, condicionando e habilitando a ação, mas também a própria capacidade de agência. Vista correntemente na literatura como potencialmente transformadora, ela também condiciona a ação dos agentes, pois suas capacidades projetivas tendem a ser guiadas por condutas do passado, no sentido de vincular suas ações à trajetória social e intelectual vivida no campo, podendo acarretar maior conformidade e habitualidade na pesquisa. Denominamos esse fenômeno como paradoxo da capacidade de agência, pois a mesma via que habilita a ação também a limita cognitivamente.In this article, we examine the role of the agency in the construction of scientific knowledge under the assumptions of structurationism. For this purpose, the notion of agency has been empirically treated from the social network analysis, with the indicators being the centrality, productivity and preferential attachment of researchers in the field of organizational studies and strategy in Brazil. We analyzed 2,072 researchers, in that we highlight the role of some of them, classified as continuants, in order to evaluate structural indicators in more detail, in addition to the trajectory of their academic production. Our findings allow us to affirm that it is not only the social structure that shows duality, conditioning and enabling the action, but also the capacity of agency itself. Currently viewed in the literature as a transforming capacity, it also conditions the action of agents because their projective capacities tend to be guided by past conduct in that they link their actions to the social and intellectual trajectory they have experienced in the field, bringing greater conformity and habitualness to research. We have addressed this phenomenon into a cognitive realm and have called it as paradox of agency capability

Voisin Rational Grazing as a Sustainable Alternative for Livestock Production

Current livestock practices do not meet current real-world social and environmental requirements, pushing farmers away from rural areas and only sustaining high productivity through the overuse of fossil fuels, causing numerous environmental side effects. In this narrative review, we explore how the Voisin Rational Grazing (VRG) system responds to this problem. VRG is an agroecological system based on four principles that maximise pasture growth and ruminant intake, while, at the same time, maintaining system sustainability. It applies a wide range of regenerative agricultural practices, such as the use of multispecies swards combined with agroforestry. Planning allows grazing to take place when pastures reach their optimal resting period, thus promoting vigorous pasture regrowth. Moreover, paddocks are designed in a way that allow animals to have free access to water and shade, improving overall animal welfare. In combination, these practices result in increased soil C uptake and soil health, boost water retention, and protect water quality. VRG may be used to provide ecosystem services that mitigate some of the current global challenges and create opportunities for farmers to apply greener practices and become more resilient. It can be said that VRG practitioners are part of the initiatives that are rethinking modern livestock agriculture. Its main challenges, however, arise from social constraints. More specifically, local incentives and initiatives that encourage farmers to take an interest in the ecological processes involved in livestock farming are still lacking. Little research has been conducted to validate the empirical evidence of VRG benefits on animal performance or to overcome VRG limitation

Caracterização de genótipos de feijão-caupi [Vigna unguiculata (L.) WALP.] quanto à precocidade e à arquitetura.

Com o objetivo de verificar a existência de variabilidade genética e identificar genótipos de feijão-caupi de ciclo precoce, porte ereto, com hábito de crescimento determinado e produtivos, realizou-se um experimento no delineamento experimental de blocos casualizados, com 22 tratamentos e quatro repetições. Foram avaliados os caracteres floração inicial, maturidade, comprimento do hipocótilo, comprimento do epicótilo, comprimento do ramo principal, número de nós no ramo principal, número de ramos laterais, número de nós dos ramos laterais, ângulo de inserção do primeiro ramo lateral, ponto de colheita, acamamento e produtividade de grãos (Kg.ha-1). Os efeitos de tratamentos foram significativos para a maioria dos caracteres avaliados, com exceção do comprimento do hipocótilo e ângulo de inserção do primeiro ramo lateral. Os genótipos mais precoces foram, respectivamente: IT82D-889, AU94-MOB-816, IT82D-60, IT82E-49, IT82G-9 e MNCOO-544-14-1-2. Os genótipos com melhor arquitetura da planta foram, respectivamente: IT82G-9, IT82D-889 e AU-94-MOB-816. A maior produtividade de grãos foi expressa pelo genótipo TVX5058-09C-02, com 2.029,84 kg.ha-1, seguido pelos genótipos TE97-418-07-1 (1.587,9 kg.ha-1), UCR-95-701 (1.576,5 kg.ha-1), MNCOO544D-10-1-2-2 (1.548,6 kg.ha-1) e IT93K-93-10 (1.509,3 kg.ha-1), embora, não tenha diferença significativa entre esses genótipos pelo teste de Scott Knott
