Relações inter-firmas em Barcarena/PA: um estudo das práticas de inovação e cooperação na rede de fornecedores e subcontratados da IRCC

Este trabalho tem como objetivo apresentar um estudo das relações inter-firmas estabelecidas entre empresas mínero-metalúrgicas localizadas no distrito industrial do município de Barcarena, no estado do Pará, a partir da análise das interações entre uma empresa central e sua rede de fornecedores e subcontratados, que operacionalizam o beneficiamento e a exportação do mineral conhecido como caulim. Segundo as abordagens teóricas que defendem a ocorrência e a disseminação de inovações tecnológicas como base para o desenvolvimento econômico, realizou-se um estudo sobre a forma como os arranjos produtivos são capazes de gerar e manter vantagens competitivas a partir de sistemas de inovação baseados em redes cooperativas integradas por um grupo específico de agentes públicos e privados. Os resultados da pesquisa mostram que, em que pese a existência de inovações nos processos produtivos, em função das exigências técnicas apresentadas por seus contratantes, as empresas subcontratadas, via de regra, não conseguem estabelecer relações de cooperação capazes de promover a disseminação destas inovações, assim como também geralmente não dispõem de recursos gerenciais e tecnológicos capazes de gerar inovações de produtos ou de transformar as inovações de processos em significativos ganhos de produtividade. A ausência de cooperação entre as empresas estende-se aos relacionamentos com os outros agentes, tais como instituições de ensino e pesquisa, de treinamento e capacitação técnica, órgãos de fomento e crédito, associações, cooperativas e sindicatos. Conseqüentemente, a rede de subcontratação desperdiça o potencial de ganhos sinérgicos capazes de elevar os patamares de competitividade local. Abordam-se também as implicações do estudo para a pesquisa, para o desenvolvimento local e para o planejamento e as políticas públicas.

Interações nas danças circulares do Mana-Maní em Belém do Pará

Esta pesquisa prioriza abordagens que estudam a comunicação enquanto interação entre pessoas. O objetivo geral foi identificar, compreender e interpretar as interações que ocorrem nas danças circulares do Mana-Maní em Belém do Pará. Especificamente buscou-se identificar a dimensão comunicativa das ações individuais e coletivas que ocorrem na dança circular e verificar de que maneira a dimensão comunicativa das interações favorecem as interações simbólicas na dança circular, além de descrever as interações comunicativas que ocorrem nas danças circulares do Mana- Maní. O aporte teórico fundamentalmente discutiu dispositivos interacionais em José Luiz Braga; Espírito Comum e Sociedade Midiatizada em Raquel Paiva e Muniz Sodré e Comunidade Emotiva e Percepção do Mundo Sensível em Michel Mafessoli. Desse modo fez-se um tencionamento entre teorias e pesquisa empírica, sobre as observações em um contexto compreendido a partir de interpretações do pesquisador. Ao nível da abordagem metodológica, utilizou-se um enfoque prevalentemente qualitativo (interpretativo), que se pautou na abordagem fenomenológicopragmática, buscando revelar características intrínsecas, ações e reações que ora promovem, ora decorrem das interações observadas no contexto do grupo. Trabalhou-se com pesquisa bibliográfica e de campo, com a observação participante, diário de campo, entrevistas em profundidade e não estruturadas, aplicação de formulário semi-estruturado e coleta de depoimentos de participantes e ex participantes. Quanto às implicações práticas, buscou-se compreender formas de comunicação ocorridas partir de uma vivência sociocultural, dentro de um contexto especificamente observado, reconhecendo influências externas e internas que propiciam interações comunicativas. Quanto aos resultados, compreendeu-se que as interações ocorrem nas danças circulares do Mana-Maní a partir da inter-relação entre cinco elementos: 1) o eu, parte fundamental e insubstituível, que agrega motivações pessoais para vivenciar as danças circulares; 2) o outro – matéria-prima para as diversas interações, sempre de forma assimétrica, conforme o cabedal de conhecimento de cada um. Sem o outro, não há interação; 3) a ritualística das danças circulares no Mana-Maní, inspirada nas matrizes culturais da Amazônia, que com sua filosofia estimula e permite um espírito mais meditativo e interativo entre os participantes; 4) o cotidiano, por conta do reencantamento, a partir do prazer de participar e de ter inspirações para enfrentar dificuldades, desafios, limites físicos, psíquicos e comunicativos do comportamento pessoal; 5) a intersubjetividade, que ocorre de forma relevante e intensa, partir das dimensões simbólica e intersubjetiva, onde cada participante projeta seu mundo, sua subjetividade e entra em contato com a subjetividade dos demais, criando e ressignificando interações.

Variação inter-sexual na frequência de cromossomos Bs em Corydoras aeneus (Siluriformes: Callichthyidae)

The genus Corydoras, the highest among the Siluriformes, Callichthyidae is owned by the family, consisting of 177 valid species and widely distributed in cis-Andean portion of South America How striking feature has two longitudinal series of dermal plates covering almost the entire body. Cytogenetic studies in Callichthyidae show many chromosomal rearrangements, including events of polyploidy in their evolutionary history, particularly the genus Corydoras, in which the variation is the diploid number of 2n = 40 to 2n = 134 chromosomes. The absence of information on the frequency of chromosomes in the group Bs motivated this work with the species Corydoras aeneus. A population from the Tietê River basin in Ribeirão Claro (subbasin Corumbataí - Rio Claro, SP) was sampled a total of 20 subjects (10 males and 10 females) and 30 metaphases per individual were analyzed cytogenetically. Were carried out by impregnation techniques silver (Ag-NOR). The observed modal diploid number was 2n = 60 (26m +26 sm +8 st), with the variable occurrence of 1 or 2 Bs chromosomes in males and a B chromosome in females, both acrocentric. Regarding the variation in the frequency of chromosome Bs, the occurrence of two B chromosomes is directly linked to males, because there were no female sampled with the occurrence of two chromosomes Bs The low frequency of Bs in females suggests that this event can be sporadic this sex, different from males in which this appears to be set supernumerary chromosome showing a higher frequency of 2 Bs than the actual modal number of 2n = 60. Further studies will be performed to understand the dynamics of the B chromosome in the population

Metabolism of L929 cells after contact with acrylic resins. Part 1: Acrylic denture base resins

The purpose of this study was to evaluate the effectiveness of complementary heat treatment and water storage in reducing cytotoxicity of acrylic resins denture bases used in Brazil by the MTT assay. Material and Methods: First, nine specimens were fabricated from metal matrix in the form of discs with 14 mm in diameter and 1.2 mm of thick. Immediately after making, 24 or 48 hours after storage in distilled water, the samples of heat-polymerized resins were divided into 3 groups (n = 3) according to the type of thermal treatment: Group 1: samples were individually exposed to microwave energy (500 W for 3 minutes); Group 2: samples were immersed in water at 550 C for 60 minutes; Group 3: samples did not receive heat treatment. To prepare the extracts, 3 samples of each group were placed into vials containing 3 mL of culture medium and stored at 37°C for 24 hours. L929 cells were used and the MTT assay was performed to analyze the cellular metabolism. Two-factor analysis of variance was used to detect significant among groups at 5% significance. Results: After statistical analysis, the materials were classified according to the cytotoxic effect: non-cytotoxic, slightly cytotoxic; moderately cytotoxic; and strongly cytotoxic. The results showed that the resins ranged from moderately cytotoxic to non-cytotoxic, but no statistically significant difference among experimental groups. Furthermore, the water storage and thermal treatments reduced the cytotoxicity of the resins. Conclusions: It was concluded that the resins studied are potentially toxic and that treatments can decrease their cytotoxicity.

O Núcleo UHUU de pesquisa da performance: inter-ação e inter-locus-ação

The 'Performance Research UHUU Centre: interarts and multimedia' of Unesp Bauru is a possibility, among countless attempts, to break off the distance between the show and the audience, imposed by the classic dramaturgy. Seeking for re-establishing the vital energy dialogue between the artist and his public, the performance art is focused, which, opposed to the theatre orthodox conceptions (which presuppose a highlighted place to the transmitter regarding the receiver), places the public as the interlocutor and even as the message co-author. The aim of this work is to show that the UHUU Centre focus on works such as researches and productions in partnership with the Marcio Pizarro and the processes-researches-actions in partnership with the Interarts CNPq Research Group: interartistic processes and systems and performance studies.

Knowledge of nursing undergraduate students about the use of contact precautions measures

To assess knowledge of nursing undergraduate students about the use of contact precautions. Methodology. There were 106 nursing undergraduate students from three universities within the state of Sao Paulo. The data collection was done between April and May 2012. A questionnaire was elaborated with questions assessing knowledge regarding contact precautions. The data were submitted to statistical procedures in the package MINITAB version 16. The knowledge were rated as adequate, partially adequate and inadequate. Results. There was a predominance of females (86%) and age group between 20 and 29 years (70%). Regarding the definition of contact precaution of diseases in which these measures are used, undergraduate’s knowledge was partially adequate (92% and 44%, respectively). The knowledge was considered adequate for the preventive measures used during assistance (86%). As difficulties mentioned in the use of these measures were discomfort, lack of material, personnel and time. Conclusion. Although undergraduate students know what measures to be used in contact precaution, they do not have adequate knowledge about which diseases they should use them. The three participating universities should reflect on the quality of training for nursing students regarding biosecurity and contact precautions.

Computational methods for the analysis of protein structure and function

The vast majority of known proteins have not yet been experimentally characterized and little is known about their function. The design and implementation of computational tools can provide insight into the function of proteins based on their sequence, their structure, their evolutionary history and their association with other proteins. Knowledge of the three-dimensional (3D) structure of a protein can lead to a deep understanding of its mode of action and interaction, but currently the structures of <1% of sequences have been experimentally solved. For this reason, it became urgent to develop new methods that are able to computationally extract relevant information from protein sequence and structure. The starting point of my work has been the study of the properties of contacts between protein residues, since they constrain protein folding and characterize different protein structures. Prediction of residue contacts in proteins is an interesting problem whose solution may be useful in protein folding recognition and de novo design. The prediction of these contacts requires the study of the protein inter-residue distances related to the specific type of amino acid pair that are encoded in the so-called contact map. An interesting new way of analyzing those structures came out when network studies were introduced, with pivotal papers demonstrating that protein contact networks also exhibit small-world behavior. In order to highlight constraints for the prediction of protein contact maps and for applications in the field of protein structure prediction and/or reconstruction from experimentally determined contact maps, I studied to which extent the characteristic path length and clustering coefficient of the protein contacts network are values that reveal characteristic features of protein contact maps. Provided that residue contacts are known for a protein sequence, the major features of its 3D structure could be deduced by combining this knowledge with correctly predicted motifs of secondary structure. In the second part of my work I focused on a particular protein structural motif, the coiled-coil, known to mediate a variety of fundamental biological interactions. Coiled-coils are found in a variety of structural forms and in a wide range of proteins including, for example, small units such as leucine zippers that drive the dimerization of many transcription factors or more complex structures such as the family of viral proteins responsible for virus-host membrane fusion. The coiled-coil structural motif is estimated to account for 5-10% of the protein sequences in the various genomes. Given their biological importance, in my work I introduced a Hidden Markov Model (HMM) that exploits the evolutionary information derived from multiple sequence alignments, to predict coiled-coil regions and to discriminate coiled-coil sequences. The results indicate that the new HMM outperforms all the existing programs and can be adopted for the coiled-coil prediction and for large-scale genome annotation. Genome annotation is a key issue in modern computational biology, being the starting point towards the understanding of the complex processes involved in biological networks. The rapid growth in the number of protein sequences and structures available poses new fundamental problems that still deserve an interpretation. Nevertheless, these data are at the basis of the design of new strategies for tackling problems such as the prediction of protein structure and function. Experimental determination of the functions of all these proteins would be a hugely time-consuming and costly task and, in most instances, has not been carried out. As an example, currently, approximately only 20% of annotated proteins in the Homo sapiens genome have been experimentally characterized. A commonly adopted procedure for annotating protein sequences relies on the "inheritance through homology" based on the notion that similar sequences share similar functions and structures. This procedure consists in the assignment of sequences to a specific group of functionally related sequences which had been grouped through clustering techniques. The clustering procedure is based on suitable similarity rules, since predicting protein structure and function from sequence largely depends on the value of sequence identity. However, additional levels of complexity are due to multi-domain proteins, to proteins that share common domains but that do not necessarily share the same function, to the finding that different combinations of shared domains can lead to different biological roles. In the last part of this study I developed and validate a system that contributes to sequence annotation by taking advantage of a validated transfer through inheritance procedure of the molecular functions and of the structural templates. After a cross-genome comparison with the BLAST program, clusters were built on the basis of two stringent constraints on sequence identity and coverage of the alignment. The adopted measure explicity answers to the problem of multi-domain proteins annotation and allows a fine grain division of the whole set of proteomes used, that ensures cluster homogeneity in terms of sequence length. A high level of coverage of structure templates on the length of protein sequences within clusters ensures that multi-domain proteins when present can be templates for sequences of similar length. This annotation procedure includes the possibility of reliably transferring statistically validated functions and structures to sequences considering information available in the present data bases of molecular functions and structures.
