SUPPLY CHAIN RESILIENCE ANALYSIS: A BRAZILIAN AUTOMOTIVE CASE

Supply chain (SC) resilience and flexibility are important research topics receiving growing attention. However, the academic literature needs empirical studies on SC resilience capable of investigating the inter-organizational components of flexibility along different tiers. Therefore, this paper analyzes the main lack of flexibilities in three Brazilian automotive SCs that limit their resilience and therefore their capacity to better support and meet the demand changes in the marketplace. A multi-tier case study approach is adopted. Research findings identify lack of flexibilities in different tiers that inhibit the SC resilience as well as manufacturing and SC flexibilities that build SC resilience. The findings also highlight that the same SC may have the flexibility to be resilient for one of its products but not for another product, what sheds new lights on the academic literature. Finally, flexible SCs should be designed to increase SC resilience to cope with mishaps as significant demand changes.

A blockmodel study of managerial hierarchies, verbal networks, and organizational culture in four hospitals

This study demonstrates and applies a social network methodology for studying the dynamics of hierarchies in organizations. Social network (blockmodel) analysis of verbal networks in four hospitals contrasted hierarchical and structurally equivalent partitions of the sociomatrices of frequent ties and perceptions of organizational culture. It was found that the verbal networks in these organizations follow a center periphery pattern rather than a hierarchical logic and that perceptions of culture vary more by verbal network than by formal hierarchy. The perceptions of culture of central groups in one organization are much like those of peripheral groups in another. In all four hospitals, structurally equivalent social networks are more important in predicting subcultures than are hierarchical groupings and hierarchy has a limited impact on the development of verbal networks. These findings suggest the value of an amoeba rather than a pyramid metaphor in interpreting the cultures and relational structures of organizations.

Evaluation of collaborative strategies for ecotourism and recreational activities in natural parks of Rio de Janeiro

In the city of Rio de Janeiro, the management agencies of environmental conservation units of the park type have been attempting to meet five primary objectives set by the National System for Conservation Units (NSCU), using participatory management guidelines for these units. Two of these objectives relate to the development of recreation activities that involve contact with nature and ecological tourism. This article presents the analyses and conclusions regarding the implementation of collaborative strategies with businesses to achieve such objectives; it is part of a series of research studies having a broader scope. Case studies were conducted in eight parks by means of dozens of interviews with managers and other interested social actors, as well as by documentary research and direct observation. The results suggest that the ecotourism objective is still far from being reached, and that the collaborative strategies used are not sufficient to compensate for the organizational, material and human limitations that encumber these agencies. It was also concluded for the sample that there lacks a strategic vision on the part of the three branches of government involved in the management of these parks in the sense of viewing ecotourism in the city's conservation units as a powerful means to foster local sustainable development.

HUMAN T-LYMPHOTROPIC VIRUS 1 (HTLV-1) AND HUMAN T-LYMPHOTROPIC VIRUS 2 (HTLV-2): GEOGRAPHICAL RESEARCH TRENDS AND COLLABORATION NETWORKS (1989-2012)

Publications are often used as a measure of research work success. Human T-lymphotropic virus (HTLV) type 1 and 2 are human retroviruses, which were discovered in the early 1980s, and it is estimated that 15-20 million people are infected worldwide. This article describes a bibliometric review and a coauthorship network analysis of literature on HTLV indexed in PubMed in a 24-year period. A total of 7,564 documents were retrieved, showing a decrease in the number of documents from 1996 to 2007. HTLV manuscripts were published in 1,074 journals. Japan and USA were the countries with the highest contribution in this field (61%) followed by France (8%). Production ranking changed when the number of publications was normalized by population (Dominican Republic and Japan), by gross domestic product (Guinea-Bissau and Gambia), and by gross national income per capita (Brazil and Japan). The present study has shed light on some of the defining features of scientific collaboration performed by HTLV research community, such as the existence of core researchers responsible for articulating the development of research in the area, facilitating wider collaborative relationships and the integration of new authors in the research groups.

Networks in Argentine agriculture: a multiple-case study approach

Argentina is among the four largest producers of soybeans, sunflower, corn, and wheat, among other agricultural products. Institutional and policy changes during the 1990s fostered the development of Argentine agriculture and the introduction of innovative process and product technologies (no-till, agrochemicals, GMO, GPS) and new investments in modern, large-scale sunflower and soybean processing plants. In addition to technological changes, a "quiet revolution" occurred in the way agricultural production was carried out and organized: from self-production or ownership agriculture to a contract-based agriculture. The objective of this paper is to explore and describe the emergence of networks in the Argentine crop production sector. The paper presents and describes four cases that currently represent about 50% of total grain and oilseed production in Argentina: "informal hybrid form", "agricultural trust fund", "investor-oriented corporate structure", and "network of networks". In all cases, hybrid forms involve a group of actors linked by common objectives, mainly to gain scale, share resources, and improve the profitability of the business. Informal contracts seem to be the most common way of organizing the agriculture process, but using short-term contracts and sequential interfirm collaboration. Networks of networks involve long-term relationships and social development, and reciprocal interfirm collaboration. Agricultural trust fund and investor-oriented corporate structures have combined interfirm collaboration and medium-term relationships. These organizational forms are highly flexible and show a great capacity to adapt to challenges; they are competitive because they enjoy aligned incentives, flexibility, and adaptability.

Inter-relações de nitrogênio e fósforo na capacidade de combinação e na seleção em milho

Tem sido observada, em milho, a redução da absorção de nitrogênio (N), por causa da deficiência de fósforo (P), mas o efeito dessa combinação na seleção de genitores ainda precisa de estudos. Os objetivos deste trabalho foram avaliar os efeitos das inter-relações de P e N na capacidade de combinação e seleção de genitores de milho. As 28 combinações híbridas (CH), obtidas de um dialelo completo entre oito genótipos de milho e três testemunhas, foram avaliadas em quatro ambientes, obtidos pelas combinações de alta e baixa disponibilidade de P e N. Avaliaram-se o rendimento de grãos (RG) e as características secundárias: altura de plantas (AP) e espigas (AE), índice de colheita (IC), peso volumétrico (PV), prolificidade (PRL) e massa seca da parte aérea (MSPA). O efeito do estresse de N no RG foi similar em baixo e alto P. O genótipo P3041 apresentou alto RG em todos os ambientes. As correlações genéticas das características secundárias com o RG foram afetadas pelos ambientes. Em alto P, a capacidade geral de combinação (CGC) foi significativa para RG apenas em alto N. Em baixo P, a CGC apresentou significância em ambos os níveis de N. Os genótipos AG1051 e P3041 tiveram estimativas positivas de CGC em todos os ambientes. Conclui-se que, para o rendimento de grãos, a CGC somente não é importante em alto P e baixo N e a CEC não é importante em estresse de P ou N.

Inter-relações da produtividade de cana soca com a resistência à penetração, umidade e matéria orgânica do solo

A cultura da cana-de-açúcar desempenha, sobretudo no aspecto relacionado às fontes energéticas alternativas, importantíssimo papel. No ano de 2009, no município de Suzanápolis (SP), cujas coordenadas são 20º 28' 10'' S e 50º 49' 20'' W, no cerrado brasileiro foi analisada a produtividade da cana soca (2º ciclo) em razão da resistência à penetração, umidade gravimétrica e matéria orgânica de um Argissolo Vermelho eutrófico. O objetivo foi selecionar, entre os atributos pesquisados, aquele com a melhor correlação, a linear e a espacial, para explicar a variabilidade da produtividade da cana-de-açúcar. Foi instalada a malha geoestatística para a coleta de dados do solo e da planta, com 120 pontos amostrais, numa área de 14,53 ha. A matéria orgânica correlaciona-se linear e negativamente com a resistência à penetração, indicando que manejos do solo que visem seu aumento no perfil melhoram suas condições físicas e, por conseguinte, o desenvolvimento e a produtividade da cana-de-açúcar. A umidade gravimétrica (UG) e o teor de matéria orgânica do solo (MO) correlacionam-se direta, linear (UG2 e MO1) e espacialmente (UG1 e MO1) com a produtividade da cana-de-açúcar, demonstrando serem os melhores atributos, dentre os pesquisados, para estimar e aumentar a produtividade agrícola da cana-de-açúcar.

COGNITIVE LEGITIMACY, RESOURCE ACCESS, AND ORGANIZATIONAL OUTCOMES

Previous research has demonstrated the importance of developing legitimacy initiatives in order to create new business opportunities, satisfy shareholders, and obtain access to resources. Within this framework, cognitive legitimacy plays a key role. Through a case study of six Spanish public universities, the authors measure the relationship between cognitive legitimacy, access to resources, and organizational results. The results support the assertion that organizations with more cognitive legitimacy have greater access to resources and improved their results. This study contributes with muchneeded empirical research on cognitive legitimacy and demonstrates its usefulness as an explanative factor of organizational success.
