AVALIAÇÃO INSTITUCIONAL NA EDUCAÇÃO BÁSICA: UMA ANÁLISE DA PRÁTICA DA EDUCAÇÃO ADVENTISTA

O tema desta dissertação é a Avaliação Institucional da Educação Básica. Para tal, faz-se a análise do processo de avaliação, com ênfase no instrumento utilizado pelas Escolas Adventistas de nível básico do estado de São Paulo, considerando que a educação adventista se tornou uma parte consistente dentro da estrutura da Igreja Adventista do Sétimo Dia. Procurou-se, neste trabalho, como objetivo geral, compreender como se configura a prática da avaliação institucional das escolas da Rede Adventista de Educação. O método da investigação incluiu análise bibliográfica dos principais teóricos da área de políticas públicas e do sistema privado bem como da avaliação institucional, seguido de exame documental do instrumento utilizado no processo de avaliação institucional. O estudo resgata a contextualização histórica do desenvolvimento da escola privada, destacando aspectos relevantes de sua relação com o Estado. Também apresenta brevemente a história da Igreja Adventista do Sétimo Dia (IASD) nos Estados Unidos (EUA) e no Brasil, de modo a situar o surgimento do sistema educacional adventista, bem como a sua filosofia de ensino, buscando conhecer as origens desse grupo religioso que há mais de um século atua no cenário educacional brasileiro. Em seguida, aborda aspectos da Avaliação Institucional. Finalmente, apresenta-se uma síntese do processo e uma descrição analítica do instrumento de avaliação institucional das escolas de nível básico da Educação Adventista. Na conclusão do trabalho, não se encontraram indícios de que o conceito adventista de avaliação educacional seja diferente do das abordagens tradicionais. Entretanto, na concepção adventista de avaliação, existe mais fortemente a preocupação de se manter um processo de avaliação contínuo e sistemático.

Bola na rede: uma análise das estratégias comunicacionais de empresas esportivas no ambiente digital conectado

O uso das mídias sociais digitais como meio de divulgação de produtos, serviços e conteúdos organizacionais tem crescido nas últimas décadas e ganhou especial atenção nos planejamentos de comunicação organizacional e nos estudos acadêmicos sobre o tema. Nesse sentido, o segmento de empresas esportivas atua com destaque, despertando o interesse e a empatia do consumidor. Por meio de análise bibliográfica e estudo empírico, esta pesquisa teve como objetivo investigar as ações de comunicação mercadológica do segmento esportivo no ambiente digital conectado, através de um estudo de caso múltiplo das empresas Nike e Adidas. Para a obtenção dos dados, foram realizadas entrevistas em profundidade com profissionais do mercado e aplicado um protocolo de investigação de redes sociais digitais nos perfis das duas empresas. Após a coleta dos dados, estes foram analisados à luz das teorias estudadas nos capítulos iniciais (que abordaram temas como comunicação organizacional, comunicação digital, esporte e comunicação esportiva), e foi possível concluir, entre outros pontos, que, no universo do segmento esportivo, a comunicação digital conectada não prioriza o diálogo com seus públicos de interesse, sendo essencialmente baseada na divulgação unilateral de conteúdos, nem tampouco explora a potencialidade de cada uma das plataformas digitais disponíveis, replicando conteúdos em diferentes ambientes. Ficou evidente, também, o uso dos elementos constituintes do universo esportivo como argumentos estratégicos de comunicação das empresas, decorrente de sua capacidade de estreitar os laços relacionais com os públicos de interesse, por meio de seus apelos simbólicos de fácil identificação social

A IMPORTÂNCIA DAS TICS E DA EDUCAÇÃO COMO PROCESSO COMUNICACIONAL DIALÓGICO NO ENSINO SUPERIOR: Um Estudo da Universidade Estadual de Mato Grosso do Sul

Esta tese teve por objetivo saber como o corpo docente da Universidade Estadual de Mato Grosso do Sul (UEMS) percebe, entende e reage ante a incorporação e utilização das Tecnologias de Informação e Comunicação (TICs) nos cursos de graduação dessa Instituição, considerando os novos processos comunicacionais dialógicos que elas podem proporcionar na sociedade atual. Metodologicamente, a tese é composta por pesquisa bibliográfica, buscando fundamentar as áreas da Educação e Comunicação, assim como a Educomunicação; pesquisa documental para contextualização do lócus da pesquisa e de uma pesquisa exploratória a partir da aplicação de um questionário online a 165 docentes da UEMS, que responderam voluntariamente. Verificou-se que os professores utilizam as TICs cotidianamente nas atividades pessoais e, em menor escala, nos ambientes profissionais. Os desafios estão em se formar melhor esse docente e oferecer capacitação continuada para que utilizem de forma mais eficaz as TICs nas salas de aula. Destaca-se ainda que os avanços em tecnologia e os novos ecossistemas comunicacionais construíram novas e outras realidades, tornando a aprendizagem um fator não linear, exigindo-se revisão nos projetos pedagógicos na educação superior para que estes viabilizem diálogos propositivos entre a comunicação e a educação. A infraestrutura institucional para as TICs é outro entrave apontado, tanto na aquisição como na manutenção desses aparatos tecnológicos pela Universidade. Ao final, propõe-se realizar estudos e pesquisas que possam discutir alterações nos regimes contratuais de trabalho dos docentes, uma vez que, para atuar com as TICs de maneira apropriada, exige-se mais tempo e dedicação do docente.

An Integrated Framework To Improve The Concept Of Resource Specialisation.

Resource specialisation, although a fundamental component of ecological theory, is employed in disparate ways. Most definitions derive from simple counts of resource species. We build on recent advances in ecophylogenetics and null model analysis to propose a concept of specialisation that comprises affinities among resources as well as their co-occurrence with consumers. In the distance-based specialisation index (DSI), specialisation is measured as relatedness (phylogenetic or otherwise) of resources, scaled by the null expectation of random use of locally available resources. Thus, specialists use significantly clustered sets of resources, whereas generalists use over-dispersed resources. Intermediate species are classed as indiscriminate consumers. The effectiveness of this approach was assessed with differentially restricted null models, applied to a data set of 168 herbivorous insect species and their hosts. Incorporation of plant relatedness and relative abundance greatly improved specialisation measures compared to taxon counts or simpler null models, which overestimate the fraction of specialists, a problem compounded by insufficient sampling effort. This framework disambiguates the concept of specialisation with an explicit measure applicable to any mode of affinity among resource classes, and is also linked to ecological and evolutionary processes. This will enable a more rigorous deployment of ecological specialisation in empirical and theoretical studies.

Composição florística da floresta semidecídua de altitude do Parque Municipal da Grota Funda (Atibaia - Estado de São Paulo)

A floristic survey was carried out in the Grota Funda Municipal Park, Atibaia Municipality, Sao Paulo State (45º45 - 46º 45'W and 23º10 - 23º15'S), a mountainous region from 900 to 1400 meters above sea level. The climate is characterized by two seasons a hot, moist period from October to March and a dry, cold period from April to August, with frequent frosts. The sandy soil is low in fertility and highly acid at the surface. The study was done from April 1987 to November 1988. A total of 415 species were collected and identified: 362 dicotyledons belonging to 84 families and 224 genera, and 53 monocotyledons beloging to 15 families and 43 genera. Species richness in Atibaia can be attributed to environmental diversity, edaphic variation, and slight disturbance of the vegetation. A comparison with other floristic surveys in mountain forests was made and a list of the most common species of this kind of forest is presented.

Exposure of free-ranging wild carnivores, horses and domestic dogs to Leptospira spp in the northern Pantanal, Brazil

Leptospirosis is a zoonotic disease affecting most mammals and is distributed throughout the world. Several species of domestic and wild animals may act as reservoirs for this disease. The purpose of this study was to assess the exposure of free-ranging wild carnivores, horses and domestic dogs on a private reserve located in the northern Pantanal (Brazil) and the surrounding areas to Leptospira spp from 2002-2006, 75 free-ranging wild carnivores were captured in the Pantanal and serum samples were collected. In addition, samples from 103 domestic dogs and 23 horses in the region were collected. Serum samples were tested for the presence of Leptospira antibodies using the microscopic agglutination test. Thirty-two wild carnivores (42.7%) were considered positive with titres > 100, and 18 domestic dogs (17.5%) and 20 horses (74.1%) were also found to be positive. Our study showed that horses, dogs and several species of free-ranging wild carnivores have been exposed to Leptospira spp in the Pantanal, suggesting that the peculiar characteristics of this biome, such as high temperatures and an extended period of flooding, may favour bacterial persistence and transmission. In this region, wild carnivores and horses seem to be important hosts for the epidemiology of Leptospira species.

Traumas de coluna ocasionados por acidentes de transporte

Acidentes e violências são responsáveis por elevadas taxas de mortalidade e morbidade causadas pelas lesões deles decorrentes. Entre essas lesões, os traumas da coluna vertebral e, especificamente, aqueles com comprometimento da medula espinal apresentam-se como relevantes. Os acidentes de transporte em geral e os de trânsito, em especial, constituem-se, também, hoje, em um grave problema de Saúde Pública. Dados epidemiológicos sobre tais acidentes são fundamentais para que sejam feitos programas de prevenção, com a atuação de profissionais da saúde e da educação, em relação ao cumprimento de leis e normas. No caso de traumas de coluna ocasionados por acidentes de transporte, percebe-se um número elevado e preocupante. Do total de internações por traumas de coluna, 22,7 por cento no ano de 2005, foram decorrentes de acidentes de transporte. Destes, cerca de 29 por cento eram pedestres, 23 por cento ocupantes, 20 por cento não-especificados e 19,9 por cento motociclistas, quando classificados de acordo com a qualidade da vítima. É importante ressaltar que os pacientes internados por essas causas têm mortalidade hospitalar elevada e o número estimado de seqüelas é considerável

Selective Decrease of Components of the Creatine Kinase System and ATP Synthase Complex in Chronic Chagas Disease Cardiomyopathy

Background: Chronic Chagas disease cardiomyopathy (CCC) is an inflammatory dilated cardiomyopathy with a worse prognosis than other cardiomyopathies. CCC occurs in 30 % of individuals infected with Trypanosoma cruzi, endemic in Latin America. Heart failure is associated with impaired energy metabolism, which may be correlated to contractile dysfunction. We thus analyzed the myocardial gene and protein expression, as well as activity, of key mitochondrial enzymes related to ATP production, in myocardial samples of end-stage CCC, idiopathic dilated (IDC) and ischemic (IC) cardiomyopathies. Methodology/Principal Findings: Myocardium homogenates from CCC (N = 5), IC (N = 5) and IDC (N = 5) patients, as well as from heart donors (N = 5) were analyzed for protein and mRNA expression of mitochondrial creatine kinase (CKMit) and muscular creatine kinase (CKM) and ATP synthase subunits aplha and beta by immunoblotting and by real-time RT-PCR. Total myocardial CK activity was also assessed. Protein levels of CKM and CK activity were reduced in all three cardiomyopathy groups. However, total CK activity, as well as ATP synthase alpha chain protein levels, were significantly lower in CCC samples than IC and IDC samples. CCC myocardium displayed selective reduction of protein levels and activity of enzymes crucial for maintaining cytoplasmic ATP levels. Conclusions/Significance: The selective impairment of the CK system may be associated to the loss of inotropic reserve observed in CCC. Reduction of ATP synthase alpha levels is consistent with a decrease in myocardial ATP generation through oxidative phosphorylation. Together, these results suggest that the energetic deficit is more intense in the myocardium of CCC patients than in the other tested dilated cardiomyopathies.

A DNA Vaccine Encoding Multiple HIV CD4 Epitopes Elicits Vigorous Polyfunctional, Long-Lived CD4(+) and CD8(+) T Cell Responses

T-cell based vaccines against HIV have the goal of limiting both transmission and disease progression by inducing broad and functionally relevant T cell responses. Moreover, polyfunctional and long-lived specific memory T cells have been associated to vaccine-induced protection. CD4(+) T cells are important for the generation and maintenance of functional CD8(+) cytotoxic T cells. We have recently developed a DNA vaccine encoding 18 conserved multiple HLA-DR-binding HIV-1 CD4 epitopes (HIVBr18), capable of eliciting broad CD4(+) T cell responses in multiple HLA class II transgenic mice. Here, we evaluated the breadth and functional profile of HIVBr18-induced immune responses in BALB/c mice. Immunized mice displayed high-magnitude, broad CD4(+)/CD8(+) T cell responses, and 8/18 vaccine-encoded peptides were recognized. In addition, HIVBr18 immunization was able to induce polyfunctional CD4(+) and CD8(+) T cells that proliferate and produce any two cytokines (IFN gamma/TNF alpha, IFN gamma/IL-2 or TNF alpha/IL-2) simultaneously in response to HIV-1 peptides. For CD4(+) T cells exclusively, we also detected cells that proliferate and produce all three tested cytokines simultaneously (IFN gamma/TNF alpha/IL-2). The vaccine also generated long-lived central and effector memory CD4(+) T cells, a desirable feature for T-cell based vaccines. By virtue of inducing broad, polyfunctional and long-lived T cell responses against conserved CD4(+) T cell epitopes, combined administration of this vaccine concept may provide sustained help for CD8(+) T cells and antibody responses-elicited by other HIV immunogens.

Invasion of Ureaplasma diversum in Hep-2 cells

Background: Understanding mollicutes is challenging due to their variety and relationship with host cells. Invasion has explained issues related to their opportunistic role. Few studies have been done on the Ureaplasma diversum mollicute, which is detected in healthy or diseased bovine. The invasion in Hep-2 cells of four clinical isolates and two reference strains of their ureaplasma was studied by Confocal Laser Scanning Microscopy and gentamicin invasion assay. Results: The isolates and strains used were detected inside the cells after infection of one minute without difference in the arrangement for adhesion and invasion. The adhesion was scattered throughout the cells, and after three hours, the invasion of the ureaplasmas surrounded the nuclear region but were not observed inside the nuclei. The gentamicin invasion assay detected that 1% of the ATCC strains were inside the infected Hep-2 cells in contrast to 10% to the clinical isolates. A high level of phospholipase C activity was also detected in all studied ureaplasma. Conclusions: The results presented herein will help better understand U. diversum infections, aswell as cellular attachment and virulence.

Severe Plasmodium vivax malaria exhibits marked inflammatory imbalance

Background: Despite clinical descriptions of severe vivax malaria cases having been reported, data regarding immunological and inflammatory patterns are scarce. In this report, the inflammatory and immunological status of both mild and severe vivax malaria cases are compared in order to explore immunopathological events in this disease. Methods and Results: Active and passive malaria case detections were performed during 2007 in Buritis, Rondonia, in the Brazilian Amazon. A total of 219 participants enrolled the study. Study individuals were classified according to the presence of Plasmodium vivax infection within four groups: non-infected (n = 90), asymptomatic (n = 60), mild (n = 50) and severe vivax infection (n = 19). A diagnosis of malaria was made by microscopy and molecular assays. Since at present no clear criteria define severe vivax malaria, this study adapted the consensual criteria from falciparum malaria. Patients with severe P. vivax infection were younger, had lived for shorter time in the endemic area, and recalled having experienced less previous malaria episodes than individuals with no malaria infection and with mild or asymptomatic infection. Strong linear trends were identified regarding increasing plasma levels of C reactive protein (CRP), serum creatinine, bilirubins and the graduation of disease severity. Plasma levels of tumour necrosis factor (TNF), interferon-gamma(IFN-gamma) and also IFN-gamma/interleukin-10 ratios were increased and exhibited a linear trend with gradual augmentation of disease severity. Both laboratory parameters of organ dysfunction and inflammatory cytokines were reduced during anti-parasite therapy in those patients with severe disease. Conclusion: Different clinical presentations of vivax malaria infection present strong association with activation of pro-inflammatory responses and cytokine imbalance. These findings are of utmost importance to improve current knowledge about physiopathological concepts of this serious widespread disease.

Hepatitis B Infection Is Associated with Asymptomatic Malaria in the Brazilian Amazon

Background: Areas that are endemic for malaria are also highly endemic for hepatitis B virus (HBV) infection. Nevertheless, it is unknown whether HBV infection modifies the clinical presentation of malaria. This study aimed to address this question. Methodology and Findings: An observational study of 636 individuals was performed in Rondonia, western Amazon, Brazil between 2006 and 2007. Active and passive case detections identified Plasmodium infection by field microscopy and nested Polymerase Chain Reaction (PCR). HBV infections were identified by serology and confirmed by real-time PCR. Epidemiological information and plasma cytokine profiles were studied. The data were analyzed using adjusted multinomial logistic regression. Plasmodium-infected individuals with active HBV infection were more likely to be asymptomatic (OR: 120.13, P < 0.0001), present with lower levels of parasitemia and demonstrate a decreased inflammatory cytokine profile. Nevertheless, co-infected individuals presented higher HBV viremia. Plasmodium parasitemia inversely correlated with plasma HBV DNA levels (r=-0.6; P=0.0003). Conclusion: HBV infection diminishes the intensity of malaria infection in individuals from this endemic area. This effect seems related to cytokine balance and control of inflammatory responses. These findings add important insights to the understanding of the factors affecting the clinical outcomes of malaria in endemic regions.

Molecular characterization of a miraculin-like gene differentially expressed during coffee development and coffee leaf miner infestation

The characterization of a coffee gene encoding a protein similar to miraculin-like proteins, which are members of the plant Kunitz serine trypsin inhibitor (STI) family of proteinase inhibitors (PIs), is described. PIs are important proteins in plant defence against insects and in the regulation of proteolysis during plant development. This gene has high identity with the Richadella dulcifica taste-modifying protein miraculin and with the tomato protein LeMir; and was named as CoMir (Coffea miraculin). Structural protein modelling indicated that CoMir had structural similarities with the Kunitz STI proteins, but suggested specific folding structures. CoMir was up-regulated after coffee leaf miner (Leucoptera coffella) oviposition in resistant plants of a progeny derived from crosses between C. racemosa (resistant) and C. arabica (susceptible). Interestingly, this gene was down-regulated during coffee leaf miner herbivory in susceptible plants. CoMir expression was up-regulated after abscisic acid application and wounding stress and was prominent during the early stages of flower and fruit development. In situ hybridization revealed that CoMir transcripts accumulated in the anther tissues that display programmed cell death (tapetum, endothecium and stomium) and in the metaxylem vessels of the petals, stigma and leaves. In addition, the recombinant protein CoMir shows inhibitory activity against trypsin. According to the present results CoMir may act in proteolytic regulation during coffee development and in the defence against L. coffeella. The similarity of CoMir with other Kunitz STI proteins and the role of CoMir in plant development and plant stress are discussed.
