As empresas de pequeno e médio portes (PME´s) têm procurado estabelecer várias formas de cooperação atualmente, objetivando se manterem competitivas num mercado cada vez mais globalizado. As redes de empresas representam um tipo de cooperação bastante funcional para PME´s. As redes assumem várias formas, dentre elas: os consórcios de exportação, os arranjos produtivos locais ou clusters industriais, as cooperativas, os aglomerados, as organizações virtuais. O consórcio de exportação, que é a união de empresas de pequeno e médio porte do mesmo segmento produtivo e/ou complementares para juntas exportarem seus produtos, pode ser apontado como uma importante estratégia para a inserção daquelas empresas no mercado internacional. A sinergia obtida proporciona as seguintes vantagens para as empresas participantes: redução de custos gerais de exportação (em especial a promoção), minimização do risco de exportar individualmente, aumento de competitividade das empresas, efeito motivador sobre os participantes, maior segurança na penetração e diversificação de mercados, alavancagem das vendas externas, possibilidade de exportar com marca própria, maior poder político em negociações com entidades de apoio ao comércio exterior...

O objetivo principal desta Tese é analisar e compreender as particularidades dos processos de criação de Consórcios Intermunicipais em três Estados brasileiros. Os Consórcios analisados são o Consórcio Intermunicipal de Produção e Abastecimento de São Luís (MA); o Consórcio Intermunicipal das Bacias do Alto Tamanduateí e Billings (Grande ABC-SP); os Consórcios Intermunicipais de Saúde de Minas Gerais. A questão central que orientou esta pesquisa foi a seguinte: como surgem os Consórcios Intermunicipais no Brasil, ao longo dos anos 90? Para responder esta questão, o trabalho foi estruturado a partir de três recortes: teórico, temático e empírico. Por meio do recorte teórico foi possível apresentar um arcabouço respaldado principalmente no que se convencionou chamar de formação de agendas de governo. Por meio do recorte temático foi possível localizar este estudo na órbita das questões relativas aos municípios brasileiros, bem como situar o debate sobre a cooperação intermunicipal ao longo do tempo. Por meio do recorte empírico realizou-se a pesquisa de campo orientada pela teoria previamente analisada. A hipótese central desta Tese é a de que a criação dos Consórcios Intermunicipais depende de dinâmicas locais nas quais dois fatores são fundamentais: a presença de um empreendedor de políticas públicas e a identificação de uma janela de oportunidades. Em outras palavras: os Consórcios Intermunicipais resultam de formas peculiares de como se articulam os interesses locais em torno de determinado "setor" de políticas públicas.; The main goal of this thesis is to analyse and comprehend the circumstances of the Intermunicipalities Consortia creation processes in three different Brazilian States. The Consortia chosen for analysis are: São Luis Intermunicipal Consortium of Production and Supply (MA)...

Este trabalho visa propor um sistema consorciado para a manutenção da sinalização urbana em municípios de pequeno porte. A viabilidade do uso do consórcio foi verificada através da análise comparativa de custos e da carga operacional de uma central de atendimento para todas as cidades e da instalação de um centro de serviços em cada cidade. Um sistema de informações geográficas (TransCAD) foi usado para simular dois cenários: o serviço de manutenção a partir de uma central que atende todas as cidades versus um centro de atendimento em cada cidade. A viabilidade do uso do consórcio intermunicipal proposto é demonstrada através de um estudo de caso compreendendo 18 cidades na região central do estado de São Paulo. Os resultados finais mostram que os objetivos iniciais propostos foram alcançados.; The objective of this research was to propose the use, by small towns, of intercity consortia for the maintenance of traffic signs and road markings at urban intersections. The comparison was made in terms of total costs and operational load for a central service center, as opposed to the costs and operational loads of service centers located in each town. A geographical information system (TransCAD) was used to simulate two scenarios: maintenance services from a central location...

A biomassa lignocelulósica é a fonte de energia renovável mais abundante no planeta, sendo fonte de açúcares que podem ser fermentados para a obtenção de etanol. No entanto, devido a sua alta recalcitrância, poucos microrganismos conseguem hidrolisar a celulose com alta eficiência. Na natureza, esta degradação é realizada por diferentes espécies de microrganismos atuando de modo sinérgico. O objetivo principal deste trabalho é verificar a degradação de celulose por consórcios microbianos. Vinte e sete microrganismos isolados do manguezal da Estação Ecológica de Carijós (Florianópolis, Brasil), foram agrupados em comunidades e cultivados utilizando como substratos bagaço de cana-de-açúcar, celobiose e carboximetilcelulose. Após o período de incubação, a geração de açúcares fermentáveis foi avaliada utilizando-se o método do ácido 3,5-dinitrosalicílico, assim como a formação de biofilme na biomassa lignocelulósica através de microscopia eletrônica de varredura. Para as comunidades crescidas em carboximetilcelulose, também foi determinada a atividade das enzimas celulolíticas, pelo método do papel filtro. As comunidades não demonstraram muita eficiência na degradação do bagaço de cana-de-açúcar e carboximetilcelulose...

A biodegradação de poluentes de petróleo em um solo contaminado foi acompanhada neste estudo, avaliando o comportamento da microbiota do solo durante a utilização de hidrocarbonetos policíclicos aromáticos (HPAs) como fontes de carbono. Através da biomassa microbiana, da taxa de respiração no solo, bem como do quociente metabólico (eficiência em degradar os compostos recalcitrantes em questão), foi possível uma avaliação do impacto na microbiota nativa do solo contaminado e nos diferentes microcosmos bioaumentados com os consórcios de bactérias, fungos, e uma mistura destes consórcios por 12 semanas. Tanto a microbiota nativa quanto os solos bioaumentados demonstraram uma rápida resposta à adaptação neste ambiente contaminado pelo aumento da biomassa e das taxas metabólicas. Durante o período de biodegradação dos HPAs, valores de evolução de CO2 foram diminuindo e a biomassa se manteve em crescimento estável, indicando menos gasto de energia para os microrganismos sobreviverem neste solo impactado, como resposta à boa competitividade e eficiência da microbiota nativa e bioaumentada. A biodegradação dos HPAs e a presença de metabólitos intermediários foram também avaliados, apresentando uma rápida redução das concentrações dos HPAs de baixo peso molecular (menores que 4 anéis aromáticos) em comparação com os de alto peso molecular...

Cystic Fibrosis (CF) is characterized by high rates of morbidity and mortality caused by pulmonary microbial infections. Pseudomonas aeruginosa is typically the prevailing pathogen in the airways of CF patients. However, an emergent and diverse microbial community inhabiting CF lungs has been disclosed, but how it interacts and contributes to the polymicrobial consortia with CF-common pathogens is still to be revealed. The mail goal of this study was to address the behavior of two CF-atypical bacteria, Inquilinus limosus (IL) and Dolosigranulum pigrum (DP), when associated to P. aeruginosa (PA) under oxygen-atmospheres resembling CF airways. For this, those bacteria were grown in dual- and three-species populations with P. aeruginosa in variable oxygen conditions and biofilms were thoroughly characterized for biomass, activity, CFU numbers, antibiotic resistance profiles and relative distributions of bacterial populations. Dual-species consortia were of difficult eradication, with most antibiotics being ineffective in reducing biofilm-bacteria, particularly under low-oxygen atmospheres. Regarding microbial composition, these biofilms presented similar bacterial proportions, whereas P. aeruginosa and D. pigrum dominated the three-species consortia...

Internationalization has been widely studied throughout the years. Broadly, it has been predicted as irrevocable and having increasing impact on firm-related strategy. Within entry modes, consortium, has not received as much attention as others. Hence, it seems important to understand how this specific entry mode allows the entrance of firms in the international markets. This study intends to answer the question of “how” to internationalize, anticipating the consortium as the most feasible way for construction firms to enter certain markets. The reasons that determine its choice concern the specificness of the projects, markets and of the firm. In the first part of the study, we review the existent literature on consortia as an entry mode and as a tool of internationalization used by construction firms. Through this review we build a framework that reveals the motivations that lead to this choice. In the second part, we present the case study of Mota-Engil, as a potential source of valuable information which may contribute to the understanding of the phenomenon under study. This case study corroborates the motivations found to create consortia. The paper closes with its contributions, limitations and suggestions for future researches.

Paper also presented at: 2nd Annual Copenhagen Conference on Partnerships: crating innovative solutions through collaboration, Copenhagen, 17-18 November.; The phenomenon of internationalization has been actively studied, throughout the years. In its wide approach, it has been predicted as irrevocable and of increasing impact in the firm-related strategy. The way by which the internationalization occurs is connected with the modes used to enter in foreign markets, which have been also industriously scrutinized. One of those modes, the consortium, has not received as much attention as others. Thus, it seems important to understand how consortia allow the settlement of firms in the international markets. This study intends to answer the question of “how” to internationalize, anticipating the consortium as the most feasible way for construction firms to enter in certain markets. The reasons which determine its choice are related with aspects concerning the specificness of the projects, markets and of the firm in question. In the first part of the study, is introduced the revision of literature already existing about consortia as a entry mode and a tool of internationalization used by construction firms, resulting a analysis matrix which reveals the motivations conducive to their choice.

Four methanogenic consortia which degraded 2-chlorophenol, 3-chlorophenol, 2-chlorobenzoate, and 3-chlorobenzoate, respectively, and one nitrate-reducing consortium which degraded 3-chlorobenzoate were characterized. Degradative activity in these consortia was maintained by laboratory transfer for over 2 years. In the methanogenic consortia, the aromatic ring was dechlorinated before mineralization to methane and carbon dioxide. After dechlorination, the chlorophenol consortia converted phenol to benzoate before mineralization. All methanogenic consortia degraded both phenol and benzoate. The 3-chlorophenol and 3-chlorobenzoate consortia also degraded 2-chlorophenol. No other cross-acclimation to monochlorophenols or monochlorobenzoates was detected in the methanogenic consortia. The consortium which required nitrate for the degradation of 3-chlorobenzoate degraded benzoate and 4-chlorobenzoate anaerobically in the presence of KNO3, but not in its absence. This consortium also degraded benzoate, but not 3-chlorobenzoate, aerobically.

Motile phototrophic consortia are highly regular associations in which numerous cells of green sulfur bacteria surround a flagellated colorless β-proteobacterium in the center. To date, seven different morphological types of such consortia have been described. In addition, two immotile associations involving green sulfur bacteria are known. By employing a culture-independent approach, different types of phototrophic consortia were mechanically isolated by micromanipulation from 14 freshwater environments, and partial 16S rRNA gene sequences of the green sulfur bacterial epibionts were determined. In the majority of the lakes investigated, different types of phototrophic consortia were found to co-occur. In all cases, phototrophic consortia with the same morphology from the same habitat contained only a single epibiont phylotype. However, morphologically indistinguishable phototrophic consortia collected from different lakes contained different epibionts. Overall, 19 different types of epibionts were detected in the present study. Whereas the epibionts within one geographic region were very similar (Dice coefficient, 0.582), only two types of epibionts were found to occur on both the European and North American continents (Dice coefficient...

Industrial-scale biofuel production requires robust enzymatic cocktails to produce fermentable sugars from lignocellulosic biomass. Thermophilic bacterial consortia are a potential source of cellulases and hemicellulases adapted to harsher reaction conditions than commercial fungal enzymes. Compost-derived microbial consortia were adapted to switchgrass at 60°C to develop thermophilic biomass-degrading consortia for detailed studies. Microbial community analysis using small-subunit rRNA gene amplicon pyrosequencing and short-read metagenomic sequencing demonstrated that thermophilic adaptation to switchgrass resulted in low-diversity bacterial consortia with a high abundance of bacteria related to thermophilic paenibacilli, Rhodothermus marinus, and Thermus thermophilus. At lower abundance, thermophilic Chloroflexi and an uncultivated lineage of the Gemmatimonadetes phylum were observed. Supernatants isolated from these consortia had high levels of xylanase and endoglucanase activities. Compared to commercial enzyme preparations, the endoglucanase enzymes had a higher thermotolerance and were more stable in the presence of 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]), an ionic liquid used for biomass pretreatment. The supernatants were used to saccharify [C2mim][OAc]-pretreated switchgrass at elevated temperatures (up to 80°C)...

Scientific research has shifted from studies conducted by single investigators to the creation of large consortia. Genetic epidemiologists, for example, now collaborate extensively for genome-wide association studies (GWAS). The effect has been a stream of confirmed disease-gene associations. However, effects on human subjects oversight, data-sharing, publication and authorship practices, research organization and productivity, and intellectual property remain to be examined. The aim of this analysis was to identify all research consortia that had published the results of a GWAS analysis since 2005, characterize them, determine which have publicly accessible guidelines for research practices, and summarize the policies in these guidelines. A review of the National Human Genome Research Institute’s Catalog of Published Genome-Wide Association Studies identified 55 GWAS consortia as of April 1, 2011. These consortia were comprised of individual investigators, research centers, studies, or other consortia and studied 48 different diseases or traits. Only 14 (25%) were found to have publicly accessible research guidelines on consortia websites. The available guidelines provide information on organization, governance, and research protocols; half address institutional review board approval. Details of publication...

Microbially enhanced coalbed methane technology must be used to increase the methane content in mining and generate secondary biogenic gas. In this technology, the metabolic processes of methanogenic consortia are the basis for the production of biomethane from some of the organic compounds in coal. Thus, culture nutrition plays an important role in remediating the nutritional deficiency of a coal seam. To enhance the methane production rates for microorganism consortia, different types of nutrition solutions were examined in this study. Emulsion nutrition solutions containing a novel nutritional supplement, called dystrophy optional modification latex, increased the methane yield for methanogenic consortia. This new nutritional supplement can help methanogenic consortia form an enhanced anaerobic environment, optimize the microbial balance in the consortia, and improve the methane biosynthesis rate.

The global bioeconomy is generating new paradigm-shifting practices of knowledge co-production, such as collective innovation; large-scale, data-driven global consortia science (Big Science); and consortia ethics (Big Ethics). These bioeconomic and sociotechnical practices can be forces for progressive social change, but they can also raise predicaments at the interface of law, human rights, and bioethics. In this article, we examine one such double-edged practice: the growing, multivariate exploitation of Big Data in the health sector, particularly by the private sector. Commercial exploitation of health data for knowledge-based products is a key aspect of the bioeconomy and is also a topic of concern among publics around the world. It is exacerbated in the current age of globally interconnected consortia science and consortia ethics, which is characterized by accumulating epistemic proximity, diminished academic independence, “extreme centrism”, and conflicted/competing interests among innovation actors. Extreme centrism is of particular importance as a new ideology emerging from consortia science and consortia ethics; this relates to invariably taking a middle-of-the-road populist stance, even in the event of human rights breaches...

STUDY QUESTIONS: To determine factors that distinguish effective rural hospital consortia from ineffective ones in terms of their ability to improve members' financial performance. Two questions in particular were addressed: (1) Do large consortia have a greater collective impact on their members? (2) Does a consortium's economic environment determine the degree of collective impact on members? DATA SOURCES AND STUDY SETTING: Based on the hospital survey conducted during February 1992 by the Robert Wood Johnson Hospital-Based Rural Health Care project of rural hospital consortia. The survey data were augmented with data from Medicare Cost Reports (1985-1991), AHA Annual Surveys (1985-1991), and other secondary data. STUDY DESIGN: Dependent variables were total operating profit, cost per adjusted admission, and revenue per adjusted admission. Control variables included degree of group formalization, degree of inequality of resources among members (group asymmetry), affiliation with other consortium group(s), individual economic environment, common hospital characteristics (bed size, ownership type, system affiliation, case mix, etc.), year (1985-1991), and census region dummies. PRINCIPAL FINDINGS: All dependent variables have a curvilinear association with group size. The optimum group size is somewhere in the neighborhood of 45. This reveals the benefits of collective action (i.e....

Anaerobic methanotrophic archaea (ANME) play a significant role in global carbon cycles. These organisms consume more than 90% of ocean-derived methane and influence the landscape of the seafloor by stimulating the formation of carbonates. ANME frequently form cell consortia with sulfate-reducing bacteria (SRB) of the family Deltaproteobacteria. We investigated the mechanistic link between ANME and the natural consortium by examining anaerobic oxidation of methane (AOM) metabolism and the deposition of biogenetic minerals through high-resolution imaging analysis. All of the cell consortia found in a sample of marine sediment were encrusted by a thick siliceous envelope consisting of laminated and cementing substances, whereas carbonate minerals were not found attached to cells. Beside SRB cells, other bacteria (such as Betaproteobacteria) were found to link with the consortia by adhering to the siliceous crusts. Given the properties of siliceous minerals, we hypothesize that ANME cell consortia can interact with other microorganisms and their substrates via their siliceous envelope, and this mechanism of silicon accumulation may serve in clay mineral formation in marine sedimentary environments. A mechanism for biomineralization mediated by AOM consortia was suggested based on the above observations.

In Antarctica, the environmental conditions and the restrictions imposed by the Antarctic Treaty prevent inoculation with foreign bacteria. Therefore, our aim was to investigate native bacterial consortia which might serve to design bacterial formulas suitable for soil bioremediation processes at cold temperatures. Two bacterial consortia, M10 and J13, were isolated from diesel contaminated Antarctic soils. Their ability to use hydrocarbons was evaluated in vitro and by the detection of three catabolic genes (alkB, nahAc, xylE). Both consortia showed similar 16S rRNA gene profiles, suggesting the presence of the same phylotypes. Total 16S rDNA was cloned from M10 grown on diesel. Sixty clones were screened, grouped by restriction profiles of PCR-amplified inserts and sequenced. T-RFLP (Terminal-Restriction-Fragment-Length-Polymorphism) of clones showed that all phylotypes from the entire consortia were recovered. A culture-dependent approach was used to isolate M10 components able to utilise aliphatic and aromatic hydrocarbons. Pseudomonas, Stenotrophomonas, Pedobacter and Brevundimonas genera were detected. The combination of dependent and independent culture methods allowed elucidating the taxonomic composition of these native bacterial consortia. Further work will assess whether combining the isolates obtained as a defined mixed culture can enhance bioremediation of contaminated soils.; Fil: Vazquez...

7 pages, 6 figures, 1 table.-- PMID: 15300420 [PubMed].-- Printed version published Dec 2004.; Cultures of Microcoleus consortia polluted with two different types of crude oil, one with high content in aliphatic hydrocarbons (Casablanca) and the other rich in sulphur and aromatic compounds (Maya), were grown for 50 days and studied for changes in oil composition. No toxic effects from these oils were observed on Microcoleus consortia growth. In fact, the interface layer between the oils and the water culture medium proved to be the ideal site for consortia development, leading to a wrapping effect of the oil layers by these organisms. Despite this affinity of cyanobacteria for the oil substrate, the changes in oil composition were small. Microcoleus consortia did not induce transformation in the aliphatic-rich oil, and the modifications in the sulphur and aromatic-rich oil were small. The latter essentially involved degradation of aliphatic heterocyclic organo-sulphur compounds such as alkylthiolanes and alkylthianes. Other groups of compounds, such as the alkylated monocyclic and polycyclic aromatic hydrocarbons, carbazoles, benzothiophenes and dibenzothiophenes, also underwent some degree of transformation, involving only the more volatile and less alkylated homologues.; Financial contribution from the European Union MATBIOPOL project EVK3-CT-1999-00010.; Peer reviewed

Methane release from the oceans is controlled in large part by syntrophic interactions between anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria (DSS), frequently found as organized consortia. An understanding of the specifics of this symbiotic relationship and the metabolic heterogeneity existing between and within individual methane-oxidizing aggregates is currently lacking. Here, we use the microanalytical method FISH-SIMS (fluorescence in situ hybridization-secondary ion mass spectrometry) to describe the physiological traits and anabolic activity of individual methanotrophic consortia, specifically tracking ^(15)N-labelled protein synthesis to examine the effects of organization and size on the metabolic activity of the syntrophic partners. Patterns of 15N distribution within individual aggregates showed enhanced ^(15)N assimilation in ANME-2 cells relative to the co-associated DSS revealing a decoupling in anabolic activity between the partners. Protein synthesis in ANME-2 cells was sustained throughout the core of individual ANME-2/DSS consortia ranging in size range from 4 to 20 μm. This indicates that metabolic activity of the methane-oxidizing archaea is not limited to, or noticeably enhanced at the ANME−2/DSS boundary. Overall...
