CHARACTERIZATION OF AGROINDUSTRIAL SYSTEMS: A COMPARATIVE STUDY OF THE SUCRO-ENERGETIC SECTORS OF BRASIL AND COLOMBIA

Concern about the growing demand of food and fuel has focused the attention on countries with conditions to provide for global requirements. Also, the build-up of an environmental awareness has compelled several governments to implement programs for the addition of biofuels to oil derivatives. Considering their relevance as world and South American producers, this study makes a characterization of the sucro-energetic sectors of Brazil and Colombia, based on a view of agro-industrial systems, industrial organization and transaction cost economy. The approach followed considered of a secondary information survey and in-depth interviews. The main differences found are centered on institutional development level and production volumes. However, the use of the same raw material, sugarcane, trade opening policies, cultural approaches and regional integration, are factors that could generate links of commercial exchange and technological cooperation between the two countries.

Increased elastic microfibrils and thickening of fibroblastic nuclear lamina in canine cutaneous asthenia

Cutaneous asthenia is a hereditary connective tissue disease, primarily of dogs and cats, resembling Ehlers-Danlos syndrome in man. Collagen dysplasia results in skin hyperextensibility, skin and vessel fragility, and poor wound healing. The purpose of this study was to describe the histological findings in a dog with a collagenopathy consistent with cutaneous asthenia. An 8-month-old crossbreed female dog presented with lacerations and numerous atrophic and irregular scars. The skin was hyperextensible and easily torn by the slightest trauma. Ultrastructurally, the dermis was comprised of elaunin and oxytalan microfibrils. These are immature fibres in which the fibrillar component is increased but elastin is reduced. Collagen fibres were profoundly disorganized. The fibrils had a highly irregular outline and a corroded appearance when viewed in cross-section, and were spiralled and fragmented in a longitudinal view. Dermal fibroblasts displayed a conspicuous thickening of the nuclear lamina. Nuclear lamins form a fibrous nucleoskeletal network of intermediate-sized filaments underlying the inner nuclear membrane. Mutations in lamins or lamin-associated proteins cause a myriad of genetic diseases collectively called laminopathies. Disruption of the nuclear lamina seems to affect chromatin organization and transcriptional regulation of gene expression. A common link among all laminopathies may be a failure of stem cells to regenerate mesenchymal tissue. This could contribute to the connective tissue dysplasia seen in cutaneous asthenia.

Can eccentric arterial plaques alone cause flow stagnation points and favour thrombus incorporation?

We have used an experimental model of aorta stenosis, with a Plexiglas plug, simulating a stable atheromatous plaque that promotes local turbulence and thrombosis. With animal survival of more than 24 h, we followed the partial fibrinolysis of the thrombus as well as its posterior organization and incorporation to the arterial wall as a neointima for up to 30 days. The mushroom plug form permitted the development of recirculation and stasis areas around it, favouring this evolution. Despite noted limitations, this study demonstrates that thrombus incorporation can contribute to plaque extension, as it can promote recirculation and stasis areas.

Understanding and enhancing research-policy linkages in Australian housing: A discussion paper

This project aimed to develop a systematic framework for understanding the relationship between social science research and public policy, and to build more effective linkages between social researchers and policy practitioners in the Australian housing system, particularly through AHURI. The project is explicitly applied and solution-focused. It was undertaken in close collaboration with AHURI and has contributed to AHURI's overall mission and strategy to enhancing research-based housing policy. It provided an opportunity for the AHURI policy community to engage in a process of action-oriented, self-reflection around its core business of applied housing policy research.

Role of PGF(2 alpha) and oxytocin in parturition in the brushtail possum (Trichosurus vulpecula)

Maturation of the fetal pituitary and adrenal glands allows the secretion of cortisol, which in turn leads to an increase in prostaglandin and mesotocin production. The production of prostaglandin and mesotocin results in an increase in uterine contractions and initiates birth in marsupials. The major metabolite of PGF(2alpha), 13,14-dihydro-15-keto-prostaglandin F-2alpha (PGFM), has been found in the plasma of the possum at the time of birth and administration of PGF(2alpha) to female possums induced the adoption of the birth position. Evidence that mesotocin is an integral hormone of birth in the tammar wallaby indicates that both PGF(2alpha) and mesotocin or oxytocin are required for marsupial birth. The presence of PGF(2alpha) receptors in the uterus and corpus luteum of the possum, and the in vitro uterine responsiveness to PGF(2alpha) or oxytocin, were examined. PGF(2alpha) receptors were not observed in possum uteri and the inability of PGF(2alpha) to cause contractions indicates that PGF(2alpha) is not involved directly in contraction of the uterus at parturition. The presence of oxytocin and mesotocin receptors in the uterus of possoms and the ability of oxytocin to induce uterine contraction in vitro supports the view that mesotocin is required for expulsion of the young from the uterus. Low numbers of PGF(2alpha) receptors were found in the possum corpus luteum at birth, indicating an involvement of PGF(2alpha) in regression of the corpus luteum.

O estado da reforma: balan??o da literatura em gest??o p??blica (1994/2002)

O objetivo deste paper ?? demonstrar a todos aqueles que trabalham com a disciplina Administra????o P??blica quais s??o os principais autores e obras da literatura nacional/internacional recente, articulando-os sob os aspectos anal??tico, metodol??gico e te??rico-conceitual, no sentido de contribuir para a cumulatividade da gera????o do conhecimento e forma????o de panorama nessa ??rea, no per??odo selecionado (1994/2002). Para tanto, foi adotada metodologia espec??fica para esse objetivo, apresentada por KEINERT (2000) em fun????o das caracter??sticas estruturais da disciplina. A literatura foi agrupada em cinco loci contemplando a vertente p??s-burocr??tica da gest??o p??blica, os impactos da globaliza????o no aparelho do Estado, as condicionantes do ordenamento pol??tico e econ??mico nacional e internacional, as novas tend??ncias no ciclo de pol??ticas p??blicas e a gest??o de pol??ticas sociais.As principais conclus??es da pesquisa apontam para a adequa????o do instrumental anal??tico adotado para compreens??o da literatura em Administra????o P??blica e tamb??m para a baixa verticalidade e cumulatividade da pesquisa nesse campo, com pouca sistematiza????o e densidade anal??tica no que se refere a determinados temas.

Perfil dos pacientes revascularizados do miocárdio no período de 2004 a 2008 em um Hospital Universitário do Espírito Santo

Objetivo: Caracterizar os pacientes submetidos à Revascularização do miocárdio (RM); descrever o perfil clínico dos pacientes submetidos a RM e descrever o fluxo intra e extra hospitalar no perioperatório desses pacientes. Métodos: Foi realizado um estudo descritivo analítico de dados secundários de 147 prontuários de pacientes submetidos a RM em Hospital de ensino, Vitória, Espírito Santo, Brasil, no período entre 2004 a 2008. Para a análise dos dados foi realizado o método descritivo. Resultados: A pesquisa apontou como perfil de maior incidência para RM a predominância do sexo masculino, com faixa etária entre 50 e 69, a maioria dos pacientes tinha de uma a duas doenças associadas. Ocorrência de óbito em 11,6%. O fluxo intra-hospitalar apresentou um tempo total de espera entre o CATE (cateterismo cardíaco) e a RM com mediana de 55 dias; Houve suspensão da RM por problemas relacionados à estrutura e administração e ao paciente. O motivo mais freqüente relacionada à estrutura foi a falta de leitos no Centro de Tratamento Intensivo (CTI). Conclusão: Percebeu-se que a análise das variáveis clínicas propostas apontou para resultados compatíveis com o panorama nacional nesta área. Contudo no aspecto da trajetória foi identificada a influência de questões relacionadas à gestão de recursos humanos e de estrutura para o desenvolvimento das atividades hospitalares, tendo como resultado, a dificuldade de atendimento da demanda pela capacidade instalada, assim como a fragmentação de atividades relacionadas ao planejamento assistencial, de registros e da organização dos prontuários. Com o estudo dessas variáveis foi possível a construção de uma ficha para a coleta de dados em RM, de forma que estes oferecem subsídios para a implantação de banco de dados construído pela autora e para a implementação de ações interdisciplinares no serviço de cirurgia cardíaca do local de estudo.

A política do ensino médio integrado no Espírito Santo e a experiência de sua implantação na Escola Estadual de Ensino Médio Arnulpho Mattos

Esta dissertação teve como objeto o Ensino Médio Integrado no Espírito Santo, sua trajetória e implantação a partir do Decreto 5.154/2004. O objetivo principal foi analisar a política do ensino médio integrado à educação profissional técnica de nível médio implementada no Espírito Santo. Investigar a educação pública pressupõe contextualizar a sociedade e as construções sociais que se projetam. O ensino médio no Brasil, enquanto etapa intermediária entre o ensino fundamental e a educação superior constitui-se de grande complexidade na estruturação de políticas públicas, no que tange à sua expansão qualitativa e quantitativa. Foram estabelecidos os seguintes objetivos específicos: identificar os pressupostos teóricos e pedagógicos contidos na Proposta Pedagógica da unidade escolar EEEFM Arnulpho Mattos; analisar a matriz curricular e a proposta pedagógica; relacionar o projeto pedagógico do curso com a prática educacional relatada nos encontros com os alunos; analisar a organização escolar e sua gestão política e pedagógica em face da proposta do EMI; relacionar a proposta do EMI, o princípio da politecnia e os relatos dos alunos; mapear a oferta do EMI no estado e o seu investimento financeiro. Nesse cenário, identificamos a relação entre trabalho e educação que contextualiza a relação da escola com a sociedade no sistema capitalista, em especial no ensino médio. Assim, nossa hipótese foi que esta política tem dificuldades de alcançar seus objetivos porque sua estrutura material segue a lógica da escola capitalista, assentada na perspectiva da Teoria do Capital Humano. A formação profissional no ensino médio é uma demanda social e histórica da classe trabalhadora, que necessita ingressar mais rápido no mercado de trabalho do que os filhos das elites brasileiras. A metodologia empregada foi uma pesquisa do tipo qualitativa, sendo um estudo de caso da EEEF Arnulpho Mattos. Os procedimentos metodológicos adotados para a investigação foram: observação, entrevistas semi-estruturadas, a análise documental, a revisão bibliográfica e os princípios metodológicos inscritos na sociologia da experiência (DUBET, 1994). Na articulação desses procedimentos, verificamos que a política do ensino médio integrado no ES teve, em seu início, um planejamento de implantação bem estruturado mas interrompido e, posteriormente, caracterizou-se pela descontinuidade das ações. Ademais, constatamos que os alunos ingressam e permanecem no curso sem compreenderem de fato o que significa a formação integrada entre a área geral e a técnica/profissional. Nos grupos de discussão percebemos que bastaram alguns encontros para que se pudesse estabelecer uma visão e relação diferenciadas com a experiência social do ensino médio integrado, principalmente por serem alunos trabalhadores. Acrescentamos às nossas conclusões que há iniciativas da escola acerca da integração entre as disciplinas de formação geral e técnicas, mas sem apoio ou orientação da unidade gestora, ou seja, a Sedu. A ampliação da oferta do EMI ocorreu no estado sem investimento na formação e valorização dos professores, sem concurso público e sem uma infra-estrutura necessária para a formação de jovens e adultos com capacidade de entender e de interferir no mundo do trabalho.

Certification and integration of management systems: the experience of Portuguese small and medium enterprises

The purpose of this study was to characterize the situation of Portuguese Small and Medium Enterprises (SMEs) concerning the certification of their Quality Management Systems (QMS), Environmental Management Systems (EMS) and Occupational Health and Safety Management Systems (OHSMS), in their individually form, to identify benefits, drawbacks and difficulties associated with the certification process and to characterize the level of integration that has been achieved. This research was based on a survey carried out by the research team; it was administered to 46 Portuguese SMEs. Our sample comprised 20 firms (43%) from the Trade/Services activity sector, 17 (37%) from the Industrial sector, 5 (11%) from the Electricity/Telecommunications sector and 4 (9%) from the Construction area. All SMEs surveyed were certified according to the ISO 9001 (100%), a quarter of firms were certified according to the ISO 14001 (26.1%) and a few certified by OHSAS 18001 (15.2%). We undertook a multivariate cluster analysis, which enabled grouping variables into homogeneous groups or one or more common characteristics of the SMEs participating in the study. Results show that the main benefits that Portuguese SMEs have gained from the referred certifications have been, among others, an improvement of both their internal organization and external image. We also present the main difficulties in achieving certification. Overall, 7 of the Portuguese SMEs examined indicated that the main benefits of the IMS implementation management included costs reduction, increased employee training and easier compliance of legislation. The respective drawbacks and difficulties are also presented. Finally, we presented the main integrated items in the certified Portuguese SMEs we examined.

Glucosamine and chondroitin sulfate in the repair of osteochondral defects in dogs - clinical-radiographic analysis

Among the proposed treatments to repair lesions of degenerative joint disease (DJD), chondroprotective nutraceuticals composed by glucosamine and chondroitin sulfate are a non-invasive theraphy with properties that favors the health of the cartilage. Although used in human, it is also available for veterinary use with administration in the form of nutritional supplement independent of prescription, since they have registry only in the Inspection Service, which does not require safety and efficacy testing. The lack of such tests to prove efficacy and safety of veterinary medicines required by the Ministry of Agriculture and the lack of scientific studies proving its benefits raises doubts about the efficiency of the concentrations of such active substances. In this context, the objective of this study was to evaluate the efficacy of a veterinary chondroprotective nutraceutical based on chondroitin sulfate and glucosamine in the repair of osteochondral defects in lateral femoral condyle of 48 dogs, through clinical and radiographic analysis. The animals were divided into treatment group (TG) and control group (CG), so that only the TG received the nutraceutical every 24 hours at the rate recommended by the manufacturer. The results of the four treatment times (15, 30, 60 and 90 days) showed that the chondroprotective nutraceutical, in the rate, formulation and administration at the times used, did not improve clinical signs and radiologically did not influence in the repair process of the defects, since the treated and control groups showed similar radiographic findings at the end of the treatments.

A generic model for integration of Quality, Environment and Safety Management Systems

Purpose – The purpose of this paper is to propose a generic model of Integrated Management System of Quality, Environment and Safety (IMS-QES) that can be adapted and progressively to assimilate various Management Systems, of which highlights: ISO 9001 for Quality; ISO 14001 for Environment; OHSAS 18001 for Occupational Health and Safety. Design/methodology/approach – The model was designed in the real environment of a Portuguese Organization and 160 employees were surveyed. The rate response was equal to 86 percent. The conceived model was implemented in a first phase for the integration of Quality, Environment and Safety Management Systems. Findings – Among the main findings of the survey the paper highlights: the elimination of conflicts between individual systems with resources optimization; creation of added value to the business by eliminating several types of wastes; the integrated management of sustainability components in a global market; the improvement of partnerships with suppliers of goods and services; reducing the number of internal and external audits. Originality/value – This case study is one of the first Portuguese empirical researches about IMS-QES and the paper believes that it can be useful in the creation of a Portuguese guideline for integration, namely the Quality Management Systems; Environmental Management Systems and Occupational Health and Safety Management Systems among others.
