SOBREVIVÊNCIA ORGANIZACIONAL DAS ADMINISTRADORAS DE CONSÓRCIO NO BRASIL: UMA ABORDAGEM EVOLUCIONÁRIA
Authors: Meirelles e Silva Dimaria , Thomaz José Carlos
Published: July 2016

RESUMO A sobrevivência das empresas é tema teórico recorrente no campo da administração e da economia e tem sido explorado, sobretudo, no campo das teorias evolucionárias. O objetivo deste artigo é analisar a sobrevivência organizacional das administradoras de consórcio no Brasil a partir dessa perspectiva evolucionária. A abordagem é qualitativa, baseada em dados secundários do Banco Central e dados primários coletados por meio de entrevistas com diretores de administradoras de consórcios. Os dados foram analisados segundo a técnica da análise de conteúdo. A análise com base na ecologia populacional e na economia evolucionária permitiu identificar: movimento de fusões e aquisições e seus motivos; mudanças ambientais; alinhamento estratégico; relação entre os agentes; efeitos de idade e tamanho e aspectos da gestão, como financiamento interno, perfil da carteira de clientes e recursos humanos, além da inovação. Conclui-se que as dissoluções são predominantes nessa indústria (dinamismo); a sobrevivência se deve ao atendimento diferenciado e, principalmente, à inovação (alinhamento estratégico); provavelmente as mais fortes barreiras de entrada de novos competidores são a idade e o tamanho das instituições e, quanto à gestão interna, a liberdade para a fixação das taxas de administração tem sido benéfica ao diferenciar as administradoras. Palavras-chave: Teoria evolucionária. Sobrevivência organizacional. Administradoras de Consórcios. ABSTRACT Organizational survival is a recurring theme in the literature on management and economics, and has been explored, in particular, in the field of evolutionary theories. The purpose of this article is to analyze the organizational survival of Brazilian consortium managers, based on this evolutionary perspective. The approach is qualitative, using secondary data from the Central Bank and primary data collected through interviews with the directors of consortium managers. Data were analyzed using the technique of content analysis. The analysis is based on population ecology and evolutionary economics, and resulted in the identification of: a movement of mergers and acquisitions, and the reasons behind them, environmental changes, strategic alignment, relationship between the agents, effects of age and size, and aspects of management such as internal financing, profile of the customer portfolio and human resources, and innovation. It is concluded that breakups are prevalent in the industry (dynamism); survival is due to the differentiated service and especially, to innovation (strategic alignment); the strongest entry barriers faced by new competitors are probably the age and size of the institutions, and in relation to internal management, the freedom to fix management fees has been beneficial in differentiating consortium managers. Key-words: Evolutionary theory. Organizational survival. Consortium Managers.

Published: July 2016

RESUMO A estrutura de um setor é um dos fatores que atua como determinante da lucratividade de uma empresa. A empresa Alpha, objeto de estudo desta pesquisa, atua como fornecedora de insumos de tecidos para o cluster calçadista. O objetivo deste trabalho consiste em avaliar o poder de barganha dos principais compradores da empresa Alpha, seguindo a taxonomia de Porter (2004), e os efeitos que trazem sobre a lucratividade e o posicionamento desta empresa. Para tanto, realizou-se estudo de caso, utilizando-se de pesquisa documental em estudos setoriais e nos registros contábeis da empresa, e de entrevistas com os gestores da Alpha e com seus principais compradores. A contribuição do estudo consiste em detalhar os complicadores, no que tange ao poder do comprador para este negócio, e que precisam ser gerenciados. Conclui-se que o setor comprador tem propensão a exercer baixo poder de barganha sobre a empresa, com base em pesquisa de elementos do setor e entrevistas com os gestores e compradores da Alpha. Verificou-se também que o posicionamento da Alpha é alinhado em relação às condições do setor, tendo assertividade em diferenciação, o que oportuniza margens mais altas, corroborando as evidências empíricas de outros estudos sobre o cluster calçadista do RS. Palavras-chave: Poder do comprador. Competitividade. Lucratividade. ABSTRACT The structure of a sector is one of the factors that currently determines the profitability of a company. The company Alpha, studied in this research, is a supplier of fabrics for the footwear manufacturing cluster. The objective of this study is to evaluate the bargaining power of the main buyers this company, based on Porter's taxonomy (2004), and the effects on the profitability and the positioning of this company. A case study was carried out, using document research on sector studies, the accounting records of the company, and interviews with the managers of Alpha and with their main buyers. The contribution of the study is that it details the complicating factors in relation to the buying power for this business, and that need to be managed. It concludes that the buying sector tends to exert low bargaining power over the company, based on the study of elements of the sector, and interviews with managers and buyers of Alpha. It was also found that the positioning of Alpha is coherent with the conditions of the sector, with differentiation is the best strategic option, as it enables higher profit martins, corroborating empirical evidence from other studies on the footwear cluster in the state of Rio Grande do Sul. Keywords: Buyer power. Competitiveness. Profitability.
Cocaine effects on generation of reactive oxygen species and DNA damage: formation of 8-hydroxydeoxyguanosine in active abusers
Authors: Bacchi Simona , Palumbo Paola , Di Carlo Massimo , Coppolino Maria Francesca
Published: July 2016

Cocaine abuse continues to be a major public health problem in the world. An upper numbers of individuals are initiating cocaine use with a stable rate of growth each year with an increasing number of people with cocaine related problems. Following cocaine oxidative pathways a ROS formation are generated. Oxidative stress has been demonstrated to play an important role in cocaine addiction and toxicity due to its oxidized metabolites produced by cytochrome P450 during cocaine biotransformation. The ROS induced genotoxicities include DNA damage, gene mutation, chromosome aberrations and micronuclei formation. 8-Hydroxy-2’-deoxyguanosine (8-OHdG) an oxidative modified DNA product, is the most representative product that may reflect oxidative damage induced by ROS. The present study was designed to investigate whether a systemic cocaine administration and its metabolism increase 8-OHdG production. Our findings clearly showed that cocaine promoted the ROS formation with significant increased of urinary 8-OHdG and MDA with a decreased of total scavenging capacity (TSC).

Faculty Teaching Performance: Perceptions of a Multi-Source Method for Evaluation
Authors: Lyde Adrian Renea , Grieshaber David C , Byrns George
Published: July 2016

Evaluating college and university faculty teaching performance is necessary for multiple reasons, including assurance of student learning and informing administrative decision making. A holistic system of evaluating university teaching is needed due to several factors, including limitations of student evaluations and the complexity of assessing teaching performance. University faculty members were interviewed to determine their perceptions of the multi-source method of evaluating (MME) teaching performance after a revision of policies and procedures was approved. The MME is comprised of three primary data sources: student evaluations, instructor reflections describing attributes of their own teaching such as the teaching philosophy, and a formative external review. While the faculty perceived the MME as a useful tool, they believe it operates primarily to produce a summative product than work as a formative process, which counters the goal of the MME policy. A formative process would be supported by addressing several factors, including timing, accountability, and mentoring.
The Influence of Cross-Cultural Experiences & Location on Teachers’ Perceptions of Cultural Competence
Authors: Lopes-Murphy Solange , Murphy Christopher
Published: July 2016

The increasing cultural and linguistic diversity in academic settings necessitates greater cultural competence on the part of teachers, which in turn necessitates a greater understanding of both the level of cultural competence among teachers and the experiences that enhance cultural competence. Teacher educators and pre- and in-service teachers from two geographic regions in the U.S. completed a cultural competence survey, and their responses were used to construct a cultural competence score. Cultural competence scores were higher in the East location than in the Midwest location, and scores of participants were positively related to the extent of three cross-cultural experiences (speaking a foreign language, having been abroad, and having friends from other cultures). ANCOVA revealed an independent effect for teacher group and cross-cultural experiences, but not for location. The results of this study highlight the the need to improve teacher training in cultural competence and the importance to institutions of higher learning of understanding the cross-cultural experiences typical of the regions from where they draw their students.

Authors: Amato Danila Tavares , Reis Augusto Da Cunha
Published: July 2016

O Ensino Superior não se restringe à produção do conhecimento científico para a formação do profissional que atuará na sociedade, ele também se compromete com a formação humana. Desse modo, uma nova concepção de educação significativa propõe uma formação integral pautada no cidadão em suas diversas dimensões. Neste sentido, o Programa de Monitoria torna-se uma estratégia fundamental à aprendizagem significativa na medida em que possibilita a construção de saberes e a troca entre pares. Esta pesquisa é um estudo de caso sobre o Programa de Monitoria do CEFET/RJ e tem o objetivo de apresentar a percepção dos monitores do curso de Engenharia de Produção sobre o programa. Para o alcance de tal objetivo foi aplicado um questionário semiestruturado aos monitores participantes do programa em 2014. Os principais resultados indicam que, apesar de o programa proporcionar inúmeros benefícios à formação acadêmica e pessoal dos estudantes, a monitoria ainda não foi internalizada como uma cultura pelo corpo discente, o que exige da instituição uma política de divulgação mais ampla sobre o programa.

Authors: Carmo Laiane Oliveira , Nobre Fernanda Silva de Melo , Ruiz-Esparza Daniela Pinheiro Bitencurti
Published: July 2016

A destinação adequada de resíduos sólidos tem sido uma preocupação frequente no Brasil, principalmente, depois de sancionada a Política Nacional de Resíduos Sólidos, que determina a substituição de lixões por aterros sanitários. Diante dessa preocupação, a implantação dos aterros sanitários tem como aliado importante, o geoprocessamento, que atua na prévia de escolha de região adequada ou na confirmação da mesma na construção de aterros. Nesse sentido, o presente trabalho tem como objetivo avaliar a adequabilidade das áreas que foram escolhidas para a construção dos aterros sanitários no Estado de Sergipe, utilizando principalmente, os dados de hidrografia, tipo e uso do solo das áreas de estudo sendo processados através do software AcGIS, versão 10.1. A partir dos resultados obtidos, observou-se uma irregularidade relacionada ao fato das sedes municipais em estudo estarem parcialmente inseridas no raio de 2000 m no entorno dos respectivos aterros sanitários, podendo ser um risco a saúde pública. Desse modo, conclui-se que o geoprocessamento é uma importante ferramenta no processo de avaliação da localização adequada para a construção de aterros sanitários e, consequentemente, contribui para a melhoria na qualidade ambiental e para a proteção da saúde pública.
Characterization of non-dispersive infrared gas detection system for multi gas applications
Authors: Mikuta Reinhard , Silinskas Mindaugas , Bourouis Riad , Kloos Sven , Burte Edmund P.
Published: July 2016

In this work, we present a low cost multi gas detection system for
simultaneous measurement of up to three gases. The main conclusions
are based on the investigation of the concentrations of CO2
gas as well as of CH4 gas and of H2O vapor. It was
found that the continuous heating of the IR source and the absolute
values of thermopile voltages are not suitable parameters for the gas
detection because of their high sensitivity to the influence of
temperature and/or gas flow parameters. A sine like signal is
preferential for our measurement system. The amplitude of the sine is
very stable and is proportional only to the concentration of
particular gas (according to the optical filter) and is not dependent
on the concentration of other gases or on temperature. In this way,
the CO2 gas concentration can be measured from
50 ppm to 400000 ppm with the same measurement
setup. The lowest detectable concentration of CH4 was about
500 ppm.

Tolerance to Ethanol or Nicotine Results in Increased Ethanol Self-Administration and Long-Term Depression in the Dorsolateral Striatum
Authors: Abburi Chandrika , Wolfman Shannon L. , Metz Ryan A. E. , Kamber Rinya , McGehee Daniel S. , McDaid John
Published: July 2016

Ethanol (EtOH) and nicotine are the most widely coabused drugs. Tolerance to EtOH intoxication, including motor impairment, results in greater EtOH consumption and may result in a greater likelihood of addiction. Previous studies suggest that cross-tolerance between EtOH and nicotine may contribute to the abuse potential of these drugs. Here we demonstrate that repeated intermittent administration of either EtOH or nicotine in adult male Sprague Dawley rats results in tolerance to EtOH-induced motor impairment and increased EtOH self-administration. These findings suggest that nicotine and EtOH cross-tolerance results in decreased aversive and enhanced rewarding effects of EtOH. Endocannabinoid signaling in the dorsolateral striatum (DLS) has been implicated in both EtOH tolerance and reward, so we investigated whether nicotine or EtOH pretreatment might modulate endocannabinoid signaling in this region. Using similar EtOH and nicotine pretreatment methods resulted in increased paired-pulse ratios of evoked EPSCs in enkephalin-positive medium spiny neurons in DLS slices. Thus, EtOH and nicotine pretreatment may modulate glutamatergic synapses in the DLS presynaptically. Bath application of the CB1 receptor agonist Win 55,2-212 increased the paired-pulse ratio of evoked EPSCs in control slices, while Win 55,2-212 had no effect on paired-pulse ratio in slices from either EtOH- or nicotine-pretreated rats. Consistent with these effects, nicotine pretreatment occluded LTD induction by high-frequency stimulation of the corticostriatal inputs to the dorsolateral striatum. These results suggest that nicotine and EtOH pretreatment modulates striatal synapses to induce tolerance to the motor-impairing effects of EtOH, which may contribute to nicotine and EtOH coabuse.

Published: July 2016

Type 2 diabetes (T2D) is associated with increased cancer risk and cancer-related mortality. Data herein show that we generated an immunodeficient hyperinsulinemic mouse by crossing theRag1−/−mice, which have no mature B or T lymphocytes, with the MKR mouse model of T2D to generate theRag1−/−(Rag/WT) andRag1−/−/MKR+/+(Rag/MKR) mice. The female Rag/MKR mice are insulin resistant and have significantly higher nonfasting plasma insulin levels compared with the Rag/WT controls. Therefore, we used these Rag/MKR mice to investigate the role of endogenous hyperinsulinemia on human cancer progression. In this study, we show that hyperinsulinemia in the Rag/MKR mice increases the expression of mesenchymal transcription factors,TWIST1andZEB1, and increases the expression of the angiogenesis marker, vascular endothelial growth factor A (VEGFA). We also show that silencing the insulin receptor (IR) in the human LCC6 cancer cells leads to decreased tumor growth and metastases, suppression of mesenchymal markers vimentin, SLUG, TWIST1 and ZEB1, suppression of angiogenesis markers,VEGFAandVEGFD, and re-expression of the epithelial marker, E-cadherin. The data in this paper demonstrate that IR knockdown in primary tumors partially reverses the growth-promoting effects of hyperinsulinemia as well as highlighting the importance of the insulin receptor signaling pathway in cancer progression, and more specifically in epithelial–mesenchymal transition.

It is assumed that the inner cylinder is fixed while the outer one is subjected to axial motion. The governing nonlinear equation models are obtained and solved numerically using shooting quadrature. The results for velocity and temperature profiles are utilized to compute entropy generation number and the Bejan number. Relevant results are displayed graphically and discussed quantitatively.
Translation of the Voynich Manuscript using the Differential Abstraction Method
Authors: Kim Milton
Published: July 2016

A partial translation of the Voynich manuscript using the differential abstraction method is presented. This method is used to infer the meaning of Voynich characters or words, identify the probable number system found in the Voynich script, and introduce artificial breaks into a lengthy text to handle each piece separately. The advantage of differential abstraction is that the process of abstraction requires no other verification process to check the validity of the translation results. This is a very useful feature especially for the translation of unidentifiable scripts like the Voynich manuscript of unknown origin with plentiful drawings accompanied by captions. Nonetheless differential abstraction does not guarantee the final translation of the given Voynich characters or words. Instead, it is more likely to provide approximate meaning as stepping stones towards it. With the exemplary paragraph of Folio 2r, differential abstraction can result in the translation of the Voynich manuscript.

Published: July 2016

Resumo: No Brasil, a convivência público-privado no financiamento e na prestação do cuidado ganha nítidos contornos na assistência hospitalar. Os arranjos de financiamento adotados pelos hospitais (Sistema Único de Saúde - SUS e/ou planos de saúde e/ou pagamento particular) podem afetar a qualidade do cuidado. Alguns estudos buscam associar a razão de mortalidade hospitalar padronizada (RMHP) a melhorias na qualidade. O objetivo foi analisar a RMHP segundo fonte de pagamento da internação e arranjo de financiamento do hospital. Analisaram-se dados secundários e causas responsáveis por 80% dos óbitos hospitalares. A RMHP foi calculada para cada hospital e fonte de pagamento. Hospitais com desempenho pior que o esperado (RMHP > 1) foram majoritariamente públicos de maior porte. A RMHP nas internações SUS foi superior, inclusive entre internações no mesmo hospital. Apesar dos limites, os achados indicam iniquidades no resultado do cuidado. Esforços voltados para a melhoria da qualidade de serviços hospitalares, independentemente das fontes de pagamento, são prementes.

Authors: Silva Wanderson Roberto , Costa David , Pimenta Filipa , Maroco João , Campos Juliana Alvares Duarte Bonini
Published: July 2016

Abstract: The objectives of this study were to develop a unified Portuguese-language version, for use in Brazil and Portugal, of the Body Shape Questionnaire (BSQ) and to estimate its validity, reliability, and internal consistency in Brazilian and Portuguese female university students. Confirmatory factor analysis was performed using both original (34-item) and shortened (8-item) versions. The model's fit was assessed with χ²/df, CFI, NFI, and RMSEA. Concurrent and convergent validity were assessed. Reliability was estimated through internal consistency and composite reliability (α). Transnational invariance of the BSQ was tested using multi-group analysis. The original 32-item model was refined to present a better fit and adequate validity and reliability. The shortened model was stable in both independent samples and in transnational samples (Brazil and Portugal). The use of this unified version is recommended for the assessment of body shape concerns in both Brazilian and Portuguese college students.

Published: July 2016

Resumo: O estudo estimou a prevalência de estresse no trabalho no Chile e suas associações com a exposição ocupacional ao risco psicossocial e qualidade do emprego, considerando as diferenças de gênero. Estudo transversal considerando uma amostra representativa nacional de 3.010 trabalhadores/as (1.486 mulheres e 1.524 homens). Dezoito por cento da amostra relataram estresse (23,8% mulheres vs. 14,8% de homens). Aqueles expostos a riscos psicossociais têm mais chances de sofrer estresse do que os não expostos, e as mulheres têm uma maior chance de sofrer estresse do que os homens. Homens e mulheres em empregos precários têm uma chance maior de estresse em comparação com aqueles com menos precariedade do emprego. No entanto, as mulheres em empregos precários têm uma maior chance de sofrer de estresse do que os homens em cargos semelhantes. Conclui-se que as mulheres têm uma maior proporção de empregos precários, estão mais expostas a riscos psicossociais e têm maior estresse, demonstrando a existência de uma dupla discriminação, social e de gênero, no mercado de trabalho no Chile.
Expression of genes SBP and leginsulin in contrasting soybean seed coats
Authors: Bahry Carlos André , Zimmer Paulo Dejalma
Published: July 2016

ABSTRACT: Evaluation of differential candidate gene expression in contrasting soybean seeds is an auxiliary tool in the partial elucidation of processes involved in seeds formation, as well as it contributes to the generation of new information that can be used in future research or in the development of r genetic superior constitutions. The aim of this study was to evaluate the expression of two candidate genes, SBP and leginsulin genes, possibly involved in seed quality, in contrasting coats of four soybean genotypes. Two cultivars of yellow soybeans were used, BMX Potência RR and CD 202, and two lines of black soybean, TP and IAC. Gene expression was evaluated using qPCR in seven stages of development from seed coats for four genotypes, at 25, 30, 35, 40, 45, 50, and 55 days after anthesis. The design was completely randomized, with three replications. Data were subjected to analysis of variance and means compared by Tukey's test at 5% probability. SBP and leginsulin gene have higher expression in the early phases of development from seed coats of BMX Potência RR cultivar, followed by the IAC line. These genotypes are therefore of interest for further research involving these genes.

ABSTRACT: This article provides empirical evidence for the relationship between the market orientation, entrepreneurial orientation, and collaboration of external actors in the processes of incremental and radical innovations in rural enterprises. The research tested two sets of assumptions: first, the relation between contributions of strategic orientation and innovation processes; and second, collaborations of external stakeholders in the implementation of innovation processes. Data were collected from 208 rural enterprises and analyzed with the use of techniques of partial least squares structural equation modeling. Results showed that the market orientation contributes to the development of incremental innovation, and that the entrepreneurial orientation contributes to the implementation of the incremental and radical innovations. Specific agents (buyers, suppliers of goods and services, consultants, and others producers), collaborate positively in implementing incremental innovation; however, generic agents do not. The generic agents (universities and specialized public organizations) are the ones that most intervene in radical innovations. The use of consistent theory in the areas of strategy, marketing and management in identifying that some of their causal relationships are confirmed for rural businesses unlike others, due to the structure of the market and the products produced by them.

Abstract The drainages of the Iguaçu River basin, as well as the main channel of the river, have peculiar characteristics resulting from geomorphological processes in this area, including the formation of the Iguaçu River Falls. This slope in the lower portion of the basin is a biogeographical barrier to many organisms. In this study was inventoried the fish fauna of streams of the lower Iguaçu River basin, evaluating possible differences in the species composition upstream and downstream of this biogeographical barrier. Sampling were conducted between 2004 and 2013, in five streams, three upstream and two downstream of the Iguaçu River Falls, using electrofishing. The nMDS analysis was run to investigate possible groupings of similar fauna between the streams sampled. The scores of this test were tested as to the significance of groupings with the Hotelling T2 test. The indicator value method (IndVal) was used to detect the distribution of species among the groups of the streams upstream and downstream of the Iguaçu River Falls. We collected 18,908 individuals of six orders, 11 families, and 40 species. Siluriformes and Characiformes had the highest species richness; Cyprinodontiformes presented the highest abundance. Considering the species recorded, 21 are considered natives to the Iguaçu River basin, including 15 endemic, wich were found only in streams upstream of the falls. Additional 18 species were verified only in the streams downstream of such barrier. Four species were common to both stretches. The axis 1 of the nMDS separated two groups: streams upstream (S1, S2 and S3) and streams downstream of the Iguaçu River Falls (S4 and S5). The indicator species analysis also indicated a distinction between the groups of streams, that were significantly different (Hotelling's T2 = 234.36, p ˂ 0.0001). The number of endemic species in the streams upstream of the Falls (15 spp.) evidences a significant effect of isolation promoted by the Iguaçu River Falls, and confirms the role of this barrier in the vicariant processes and endemism typical of this basin. These results emphasize the importance of conserving these ecosystems, once the extinction of species in this region means the irreversible loss of them.

ABSTRACT Purpose: The aim of this research is to describe the main reasons and difficulties for women to establish businesses and to identify possible differences between those that go into industry and those that establish commerce or service businesses. Originality/gap/relevance/implications: The establishment of business is highly important for Entrepreneurship and its understanding is relevant to pinpoint the reasons and identify the difficulties that entrepreneurs have to establish their companies. Key methodological aspects: A quantitative study of 102 industry women entrepreneurs and 96 commerce/services entrepreneurs was carried out. Data were collected by a structured questionnaire and by two Likert scales, which measured reasons and difficulties in the establishment of companies. A cluster analysis was undertaken to identify possible groups of attributes related to reasons and difficulties in the establishment of enterprises to group variables. The Mann-Whitney test was employed to compare reasons and difficulties in the establishment of enterprises between the two groups (industry and commerce/service) to identify statistically significant differences. Summary of key results: Results by the Mann-Whitney test revealed that the two groups assigned the same level of importance to the reasons for business establishment: improvement difficulty in the previous job; desire to financially help offspring; re-entry into the labor market; earning lot of money. The same test showed no significant difference in importance level assigned to eight difficulties for the establishment of business: I did not believe in my own capacity; I had never had any link with other companies; I did not have any access to industry information; People did not believe in my potential; I was afraid to quit my job; I was never acquainted with a business plan; I had no money for advertising my business; I found it difficult to choose the location of the company. Key considerations/conclusions: Results show that women entrepreneurs are not a homogenous group and that there is a need for public policies that would minimize difficulties in the setting up of companies to increase women´s participation as entrepreneurs.

ABSTRACT Purpose: To highlight and analyze lifestyles of expatriate workers. Originality/gap/relevance/implications: Since the expatriation involves processes of deconstructing and reconstructing the self, it is important to recognize lifestyles invented or adapted during an international experience. Key methodological aspects: Exploratory research with qualitative approach. Data collection was carried out through focus group with managers of the same company who shared similar expatriation experiences. The transcribed material was submitted to content analysis. Summary of key results: The ways of moving around the city, the routine and the leisure activities, the sightseeing trips, the expatriation valuation and the abnegation as a way of life were observed according to control-stimulation perception. Such elements highlighted lifestyles based on the former life, in the control, in the abnegation and in the established period of validity. Proved to be consistent with immaterial labor logic that reaches the unprecedented life, requiring intellectual and affective mobilization of individuals to new situations and indicating both intensification of control and submission forms, with so far expected freedom. Key considerations/conclusions: The lifestyles, common to all research participants, were molded, intertwined and intensified in each other. They resulted from the daily shock between the non-normalizing prescriptions and the plurality of possible options lived in expatriation.

RESUMO: As bactérias do gênero Vibrio habitam ambiente tipicamente marinho e estuarino, sendo comumente isoladas de pescados. As principais espécies de Vibrio reportadas como agentes de infecções em humanos são V. vulnificus , V. parahaemolyticus , V. cholerae e V. mimicus . V. vulnificus é considerado o mais perigoso, podendo causar septicemia e levar à morte. V. parahaemolyticus é um patógeno importante nas regiões costeiras de clima temperado e tropical em todo o mundo e tem sido responsável por casos de gastroenterites associadas ao consumo de peixes, moluscos e crustáceos marinhos. V. cholerae causa surtos, epidemias e pandemias relacionados com ambientes estuarinos. V. mimicus pode causar episódios esporádicos de gastroenterite aguda e infecções de ouvido. A patogenicidade das bactérias está ligada à habilidade do micro-organismo em iniciar uma doença (incluindo entrada, colonização e multiplicação no corpo humano). Para que isso ocorra, os micro-organismos fazem uso de diversos fatores. O objetivo desta revisão foi sintetizar o conhecimento disponível na literatura sobre os fatores de patogenicidade de V. vulnificus , V. parahaemolyticus , V. cholerae e V. mimicus .

Resumo Objetivo Identificar os fatores de risco para infecção de corrente sanguínea associada ao cateter central de inserção periférica em neonatos. Métodos Estudo de coorte prospectivo conduzido em unidade de terapia intensiva com recém-nascidos submetidos à instalação de 401 cateteres centrais de inserção periférica. Características clínicas do neonato, técnica de inserção do cateter, terapia intravenosa e tempo de permanência do cateter foram testados como fatores de risco para remoção por infecção de corrente sanguínea associada ao cateter, por meio de análise bivariada e análise multivariada com regressão de Poisson. Resultados Os dados sugerem que as menores médias de peso e idade gestacional corrigida, bem como o maior tempo de permanência do cateter estiveram associados à ocorrência de infecção de corrente sanguínea associada ao cateter. A menor idade gestacional corrigida, os diagnósticos clínicos de transtorno transitório do metabolismo e apneia, e o uso do cateter de duas vias foram identificados como fatores de risco. Conclusão A menor idade gestacional corrigida do neonato, os diagnósticos clínicos de transtorno transitório do metabolismo e apneia, e o uso do cateter de duas vias foram identificados como fatores de risco para infecção de corrente sanguínea associada ao cateter central de inserção periférica em neonatos.
