The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p < 0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p < 0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

Background, aim and scope Although many recent studies have focused on sediment potential toxicity, few of them were performed in tropical shallow aquatic environments. Those places can suffer short-time variations, especially due to water column circulations generated by changes in temperature and wind. Rio Grande reservoir is such an example; aside from that, it suffers various anthropogenic impacts, despite its multiple uses. Materials and methods This work presents the first screening step for understanding sediment quality from Rio Grande reservoir by comparing metal content using three different sediment quality guidelines. We also aimed at verifying any possible spatial heterogeneity. Results and discussion We found spatial heterogeneity varying according to the specific metal. Results showed a tendency for metals to remain as insoluble as metal sulfide (potentially not bioavailable), since sulfide was in excess and sediment physical-chemical characteristics contribute to sulfide maintenance (low redox potential, neutral pH, low dissolved oxygen, and high organic matter content). On the other hand, metal concentrations were much higher than suggested by Canadian guidelines and regional background values, especially Cu, which raises the risk of metal remobilization in cases of water circulation. Further study steps include the temporal evaluation of AVS/SEM, a battery of bioassays and the characterization of organic compounds.

1. Prochilodus lineatus (Prochilodontidae, Characiformes) is a migratory species of great economic importance both in fisheries and aquaculture that is found throughout the Jacui, Paraiba do Sul, Parana, Paraguay and Uruguay river basins in South America. Earlier population studies of P. lineatus in the rio Grande basin (Parana basin) indicated the existence of a single population; however, the range of this species has been fragmented by the construction of several dams. Such dams modified the environmental conditions and could have constrained the reproductive migration of P. lineatus, possibly leading to changes in the population genetic structure. 2. In order to evaluate how genetic diversity is allocated in the rio Grande basin, 141 specimens of P. lineatus from eight collection sites were analysed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) with 15 restriction enzymes. 3. Forty-six haplotypes were detected, and 70% of them are restricted. The mean genetic variability indexes (h = 0.7721 and pi = 1.6%) were similar to those found in natural populations with a large effective size. Fst and Exact Test values indicated a lack of structuring among the samples, and the model of isolation by distance was tested and rejected. 4. The haplotype network indicated that this population of P. lineatus has been maintained as a single variable stock with some differences in the genetic composition (haplotypes) between samples. Indications of population expansion were detected, and this finding was supported by neutrality tests and mismatch distribution analyses. 5. The present study focused on regions between dams to serve as a parameter for further evaluations of genetic variability and the putative impact of dams and repopulation programmes in natural populations of P. lineatus.

The reconstruction of Extensive Air Showers (EAS) observed by particle detectors at the ground is based on the characteristics of observables like the lateral particle density and the arrival times. The lateral densities, inferred for different EAS components from detector data, are usually parameterised by applying various lateral distribution functions (LDFs). The LDFs are used in turn for evaluating quantities like the total number of particles or the density at particular radial distances. Typical expressions for LDFs anticipate azimuthal symmetry of the density around the shower axis. The deviations of the lateral particle density from this assumption arising from various reasons are smoothed out in the case of compact arrays like KASCADE, but not in the case of arrays like Grande, which only sample a smaller part of the azimuthal variation. KASCADE-Grande, an extension of the former KASCADE experiment, is a multi-component Extensive Air Shower (EAS) experiment located at the Karlsruhe Institute of Technology (Campus North), Germany. The lateral distributions of charged particles are deduced from the basic information provided by the Grande scintillators - the energy deposits - first in the observation plane, then in the intrinsic shower plane. In all steps azimuthal dependences should be taken into account. As the energy deposit in the scintillators is dependent on the angles of incidence of the particles, azimuthal dependences are already involved in the first step: the conversion from the energy deposits to the charged particle density. This is done by using the Lateral Energy Correction Function (LECF) that evaluates the mean energy deposited by a charged particle taking into account the contribution of other particles (e.g. photons) to the energy deposit. By using a very fast procedure for the evaluation of the energy deposited by various particles we prepared realistic LECFs depending on the angle of incidence of the shower and on the radial and azimuthal coordinates of the location of the detector. Mapping the lateral density from the observation plane onto the intrinsic shower plane does not remove the azimuthal dependences arising from geometric and attenuation effects, in particular for inclined showers. Realistic procedures for applying correction factors are developed. Specific examples of the bias due to neglecting the azimuthal asymmetries in the conversion from the energy deposit in the Grande detectors to the lateral density of charged particles in the intrinsic shower plane are given.

O presente trabalho tem por objetivo caracterizar a indústria gráfica do ponto de vista da gestão, tecnologia, inovação e competição. A economia ao longo de sua história foi marcante por alguma situação peculiar que a caracterizasse. Em particular a partir da década de 1960 acompanhamos o crescimento em larga escala na região do Grande ABC onde, a indústria automobilística e seus fornecedores necessitaram de maior estrutura e apoio para as suas operações, provocando alterações nos modos de atuação das empresas industriais no país. Nessa mesma direção pelas necessidades criadas à época, a indústria gráfica na região do ABC também teve seu crescimento para atender a demanda e, criando o caráter da regionalidade e se fortalecendo economicamente. Entretanto a partir da década de 1980 com as crises econômicas e a abertura de mercado, houve uma redução nos postos de trabalho, mas as empresas também alteraram as formas de produzir. O trabalho de campo foi apoiado num referencial teórico baseado na revisão bibliográfica e um roteiro de entrevistas que orientou a coleta de dados. Na presente pesquisa foram realizadas entrevistas com os sujeitos relacionados e verificação de documentos. A análise realizada buscou confrontar os dados coletados e sistematizados com o quadro conceitual utilizado para a elaboração da pesquisa, possibilitando apurar as principais transformações verificadas no segmento estudado, bem como oferecendo embasamento para a tomada de decisão dos atores econômicos envolvidos com o desenvolvimento da indústria gráfica no Grande ABC.

As demandas do cenário competitivo do século XXI obrigam empresas a criar estratégias de marketing que lhes proporcionem vantagens competitivas para atender ao mercado. A educação não tem se mantido alheia a estas mudanças. Em alguns estudos realizados, autores entendem que a mensuração da qualidade do serviço depende das percepções dos consumidores e são relativas às suas expectativas. Recentemente foi realizado estudo exploratório em universidades privadas de São Paulo, através de testes estatísticos multivariados dividido em etapas: análise fatorial exploratória, análise fatorial confirmatória e modelagem estrutural. O estudo validou a escala para mensuração dos construtos e verificou a existência de relação causal entre eles. Assim sendo, o interesse na reaplicação do modelo levou a pesquisar as Instituições de Ensino Superior, IES, Municipais do Grande ABC. O estudo visou verificar a existência de relação causal entre os construtos endógenos e exógenos e identificar a percepção do papel do professor na qualidade dos serviços recebidos. Através do Modelo de Equações Estruturais identificou-se algumas diferenças entre IES privadas e públicas, que revelam a qualidade do serviço recebido.

O trabalho faz um estudo exploratório sobre as matérias publicadas no jornal Diário do Grande ABC no período de 01/07/2006 a 30/06/2007 que abordem a saúde do idoso. Procurou-se identificar qual a temática mais presente, o foco da matéria e em que circunstâncias o idoso ganha as manchetes do maior jornal da região do ABC paulista. A proposta foi verificar quais os critérios de noticiabilidade utilizados pelo jornal para que a publicação de fatos sobre a terceira idade ganhe status de matéria jornalística, de acordo com o teórico Mário Erbolato. O resultado mostrou que, embora a quantidade de notícias sobre o idoso seja grande, escreve-se sobre o idoso e não para o idoso no referido jornal. Com o uso criativo de critérios de noticiabilidade há possibilidade de manter com maior freqüência notícias que abordem saúde para o idoso de modo interessante e útil a esse público.
