Mundos pequenos, produção acadêmica e grafos de colaboração: um estudo de caso dos Enanpads

Utilizando a base de dados dos trabalhos publicados nos Enanpads realizados em 2002-04, este artigo focaliza a área de administração da informação para realizar um estudo exploratório sobre a formação de padrões nas estruturas de disseminação do conhecimento acadêmico no Brasil, apoiado nos conceitos oriundos da análise das redes sociais e conjugados com a base proveniente da teoria dos grafos e em recursos computacionais. Procurou-se mapear os fluxos de informações que possibilitam as trocas de conhecimento através das ligações existentes no meio acadêmico. Os resultados indicam a necessidade de ampliar e estreitar os laços entre os autores, notadamente os que possuem algum grau de centralidade local, no intuito de obter o fortalecimento das instituições de ensino, de forma a quebrar as resistências à produção conjunta entre elas, em detrimento do padrão de reprodução endógena detectado.

Effectuation e causation: um estudo sobre o processo decisório empreendedor em redes de micros e pequenos supermercados

Este estudo analisa a contribuição da centralidade em redes de negócios, na elevação da complexidade da estrutura organizacional de supermercados e os possíveis efeitos dessa mudança no processo decisório empreendedor. Causation e Effectuation são processos decisórios distintos que possuem sua hora adequada de utilização. Porém, faltam estudos sobre quando os empreendedores utilizam tais processos em ambientes de redes interorganizacionais. Para preencher esse gap, a pesquisa centra-se na tipologia de rede de cooperação associativa (BALESTRIN; VARGAS, 2004; BALESTRIN; VERSCHOORE, 2008). O referencial teórico foi construído a partir dos conceitos de centralidade (FREEMAN, 1979; WASSERMAN; FAUST, 1994), laços relacionais (BURT, 1992; GRANOVETTER, 1973), complexidade da estrutura organizacional (HALL, 2004), e dos processos decisórios de Causation e Effectuation (SARASVATHY, 2001a). Inicialmente, os dados foram coletados de forma indutiva em seis casos de micros e pequenos supermercados em redes de negócios no estado do Ceará. Após analisar o conteúdo de cada caso, o pesquisador procedeu uma Análise Qualitativa Comparativa (Qualitative Comparative Analysis – QCA). As condições necessárias à adoção dos processos decisórios foram: a) a centralidade contribui para elevar a complexidade da estrutura organizacional e/ou adoção de mecanismos de controle gerencial, quando as relações são conduzidas mais por laços sociais do que por laços estratégicos; b) empreendedores adotam Effectuation e Causation independentemente da complexidade da estrutura organizacional dos supermercados. Um novo achado foi que, além dos empreendedores novatos, os experientes também variam o uso de Effectuation e Causation no início dos novos empreendimentos. Mas ao longo do tempo, ao implementarem mecanismos de controle gerencial, eles tendem a reduzir a utilização de algumas práticas efetuais, como as capacidades de experimentar e aceitar riscos e perdas. Dados complementares foram coletados e testes foram realizados por meio de Modelagem de Equações Estruturais (MEE) baseada em partial least squares (PLS). Os resultados confirmaram que: c) os laços sociais exercem mais influência que os estratégicos, na transformação da estrutura organizacional dos supermercados; d) essa transformação influencia positivamente na implantação de mecanismos de controle gerencial; e) supermercados com mecanismos de controle gerencial terão empreendedores mais propensos a adotarem o processo de Causation, e menos propensos a experimentar e aceitar riscos e perdas. Os resultados contribuem para entender quando as relações geradas em redes de cooperação, afetam a fundação e o crescimento de pequenas empresas, e onde ocorre a evolução do comportamento decisório empreendedor no tempo. De forma prática, a pesquisa demonstra aos micros e pequenos empreendedores que eles não precisam gerar muitas relações para desenvolverem seus negócios, ou seja, a posição relativa do supermercado na rede não é importante, desde que os laços sociais estejam ativos e haja engajamento nas atividades das associações. Também ensina que os empreendedores tendem a desenvolver o raciocínio causal em redes de negócios.

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

Encalhes de Cetáceos ocorridos no período de 1984 a 2005 no litoral do Rio Grande do Norte, Brasil

Strandings of live or dead aquatic mammals constitute an important instrument to provide information regarding the occurrence, biology and ecology of these species. The aim of this study was to register the stranded species of cetaceans, the frequency and the spatial-temporal distribution of theses strandings during the period of 1984 to 2005, in the coast of Rio Grande do Norte. Data was acquired through the monitoring of strandings in the north, north-west and south coast of RN, and through information obtained from institutions and newspaper archives of the State. A total of 122 strandings of cetaceans were registered along the coast of Rio Grande do Norte. Of the 14 species of cetaceans registered, four species had higher frequencies: Sotalia guianensis (n= 65), Steno bredanensis (n = 6), Globicephala macrorhynchus (n = 6) and Physeter macrocephalus (n = 7). Out of 118 strandings, 93 occurred in the south coast (78.8 %), 23 in the north coast (19.5%) and 2 (1.7%) in the north-west coast of the State. The highest frequency of strandings occurred during the months of August to March and the maximum number of strandings occurred from 2000 onwards, as a consequence of the intense monitoring of the Pequenos Cetáceos Project in Rio Grande do Norte

Icnofósseis (paleotocas e crotovinas) atribuídos a mamíferos extintos no sudeste e sul do Brasil

ICHNOFOSSILS (PALEO-BURROWS and CROTOVINES) ATTRIBUTED TO EXTINCT MAMMALS IN SOUTHEASTERN and SOUTH BRAZIL. This work presents information regarding tunnels which are attributed to large extinct mammals. These structures can be found in several places in southeastern and southern Brazil, in different types of substrate, occurring as hollow structures (paleo-burrows) or those filled with sediments (crotovines). The dimensions and osteoderm and claw imprints found along the internal walls of the paleo-burrow found on aluvial fan deposits near the town of Cristal (Rio Grande do Sul State) suggest that a dasypodid xenarthran might have dug this structure. Comparison with similar structures found in Argentina can provide more detailed information regarding the paleoecology and biostratigraphy of the organisms that made these burrows.

A Fruticultura Irrigada de pequenos produtores no Baixo-Açu: Uma análise da eficiência de custo

This work has as an objective analyze the efficiency of producers costs of the irrigation Project Baixo-Açu , and identify the determining factors of this efficiency. To achieve these targets it was estimated, in a first stage, a frontier of costs by the method, non parametric of Data Envelopment Analysis-DEA, and measured the stakes of efficiency producers. On the second stage, it was utilized the Tobit regression pattern, estimating an inefficiency function of costs, and were indentified the associated factors of resources waste. Among the results found it was noticed the existence of a high waste of resources, that represent more than 54% of effective cost. Among the factors with the highest wastes are: energy, herbicides, defensives and chemical fertilizers. In a general way, the producers presented low efficiency level and, only, two, of seventy-five researched, achieved the frontier of costs minimization. These results reveal, in a certain way, that the producers in irrigated fruit growing in the project Baixo-Açu don t seek to minimize the production costs. It was still noticed, that the reduction of resources waste, and this way the inefficiency of costs, is associated with the agriculturalist education, his experience in agriculture, his access to the technical assistance and credit
