Educação, qualificação, trabalho e políticas públicas : campos em disputas

Este artigo trata das relações entre educação, qualificação profissional, trabalho e políticas públicas, entendidas como um assunto contemporâneo e polêmico. A sua primeira parte revisa o assunto através de um levantamento da literatura internacional, contemplada em diferentes abordagens e autores. A que segue, sistematiza o tema no cenário da realidade brasileira, nas pesquisas e publicações constantes nas áreas da educação e das ciências sociais. A última, comenta as políticas públicas de educação e qualificação implementadas no Brasil a partir dos anos 50/1950, detendo-se no momento atual. Entende-se o assunto, na contemporaneidade, como parte de um debate público tensionado pelas novas exigências internacionais e do mercado local e globalizado e pelas crises, mudanças e conquistas sociais e políticas nacionais visibilizadas a partir da década de 1980.

O contributo da Gestão de Recursos Humanos para a Sustentabilidade Ambiental das Empresas Portuguesas : uma reflexão

Este estudo pretende investigar o contributo da gestão de recursos humanos para a sustentabilidade ambiental das empresas portuguesas. Pretendeu-se analisar a correlação entre os constructos consciên-cia, incentivos, motivação, confiança dos stakeholders e comportamentos ambientalmente responsá-veis dos colaboradores. Adotou-se uma metodologia exploratória no processo de recolha de dados provenientes da revisão da literatura e dados recolhidos pela aplicação de um questionário. Partiu-se de uma amostragem aleatória constituída por indivíduos acima dos 18 anos, trabalhadores por conta de outrem. Nos 326 questionários validados utilizou-se o coeficiente de Alpha de Cronbach e da técnica de análise factorial exploratória em componentes principais. Os resultados evidenciaram que os cons-tructos foram considerados estatisticamente significativos para explicar as variações nos comporta-mentos ambientalmente responsáveis. Considera-se este trabalho um contributo para o avanço no esta-do da arte das investigações nesta temática, pois foram estudados aspetos não incluídos em estudos anteriores.

O modelo organizacional, as condições de trabalho e as relações interpessoais como fatores de satisfação dos trabalhadores em regime de Outsourcing

Num mundo cada vez mais globalizado, exige-se às organizações respostas rápidas, que lhes permitam responder com eficiência e eficácia aos desafios do mercado. Para tal é fundamental que o seu capital humano apresente níveis de satisfação elevados, pois nos dias de hoje, qualquer organização tem acesso às melhores tecnologias de ponta, tornando-se assim, os recursos humanos no grande fator de diferenciação das organizações modernas. No sentido de percebermos quais os fatores que contribuem para o nível de satisfação global dos colaboradores em regime de Outsourcing desenvolveu-se o presente estudo de investigação, cujo principal objetivo foi perceber o contributo do modelo organizacional, das condições de trabalho e das relações interpessoais como fatores associados à satisfação no trabalho. Os resultados obtidos permitem-nos inferir que o modelo organizacional, as condições de trabalho e as relações interpessoais são fatores que contribuem positivamente para a satisfação no trabalho dos trabalhadores em regime de Outsourcing.

Jesuítas e Franciscanos perante a sociedade e religião nipónicas : o caso da Apologia do Japão de Valentim Carvalho

«Perguntei a Anjirô, no caso de eu ir com ele para o seu país, se as gentes do Japão se fariam cristãs. Ele respondeu que as gentes do seu país não se fariam cristãs assim de repente. Disse-me que me fariam primeiro muitas perguntas, que veriam o que responderia, e sobretudo se viveria de acordo com o que dizia.»

Sociodemographic characteristics and clinical features of patients with adult polycystic kidney disease undergoing hemodialysis

Aims:To analyze the socio-demographic and clinical characteristics of patients with adult polycystic kidney disease admitted to hemodialysis services in Northwestern Paraná state,Brazil. Methods: This was an observational, descriptive and retrospective longitudinal study. Medical records of patients with polycystic kidneys who initiated hemodialysis between 1995 and 2012, in four centers that treat patients of the coverage area of the 15th Regional Health Region of Paraná state where analyzed. Results:We found that 10.3% of hemodialysis patients had polycystic kidney disease as a leading cause of stage 5 of chronic kidney disease. The mean age of patients was 54.9±9.4 years (ranging between 27 and 74 years), with equal gender distribution and Caucasian predominance (72.9%). The average age of dialysis initiation was 50±10.2 years. The most common comorbidity was systemic hypertension (66.7%). Liver cyst was the main extra-renal manifestation (10.4%). Twenty-five percent of the patients required renal transplantation, and (22.9%) undergone nephrectomy. The most widely used classes of antihypertensive drugs were β-blockers (41.7%) and drugs that act on the renin-angiotensin system (31.3%), while 56.3% of patients were treated with recombinant human erythropoietin. Conclusions:This is a pioneering epidemiological study in Northwestern Paraná state. We found in this population a sociodemographic and clinical profile of adult polycystic kidney disease similar to that of North America and Europe, probably because the ethnic constitution of the sample was predominantly of Euro-descendants.

El impuesto al valor agregado en los contratos de campos marginales

Esta investigación dirigida por los métodos de investigación sistemático, exegético, y teleológico, pretende analizar los contratos petroleros de Campos Marginales utilizados por la legislación ecuatoriana y específicamente, el papel de Impuesto al Valor Agregado en la producción de la Curva Base; ésta, se convierte en una figura contractual innovadora que ha producido una interesante discusión a nivel nacional; sin embargo, la propuesta de este trabajo va encaminado a encontrar un mejor proceso de inversión para el Ecuador en los Campos Marginales, que le permita a nuestro país generar mayores ingresos a su favor, no solo vinculado con la generación de ingresos tributarios, sino primordialmente con las ganancias que los recursos explotados localizados en territorio nacional creen. Para cumplir con este fin, en la primera parte, hacemos una retrospectiva alrededor de los inicios de los modelos contractuales utilizados a principios del siglo veinte; a continuación, se analiza el Contrato de Campos Marginales, y sus principales componentes. En el segundo capitulo, detenemos nuestro análisis en la aplicación del Impuesto al Valor Agregado en los servicios, desde la perspectiva nacional y comunitaria (CAN), así como, exponemos el fundamento jurídico de que la “Curva Base” no es un servicio. Finalmente, en la tercera parte del estudio, analizamos al Contrato de Campos Marginales desde el punto de vista del Derecho Administrativo y observamos la posición de los actores del contrato respecto del IVA en la Curva Base de Producción. En nuestra conclusión presentamos nuestra postura sobre el IVA en el Contrato de Campos Marginales y recomendamos una nueva opción de inversión.

Actinocephalus verae (Eriocaulaceae), a new species from the Brazilian Campos Rupestres

We describe and illustrate the new species Actinocephalus verae (Eriocaulaceae: Paepalanthoideae). This species is endemic to the rocky outcrops of the Espinhacao range in Minas Gerais, Brazil. We make comparisons with Actinocephalus ithyphyllus and Actinocephalus ochrocephalus, the morphologically most similar species. The new species` morphological variation, habitat, geographic distribution, and conservation status are discussed.

Their diagnostic features are pointed out, and a discussion of their relationships to other species of Ocotea is provided.

Population biology and regeneration of forbs and shrubs after fire in Brazilian Campos grasslands

Fire is an important factor in several ecosystems, affecting plant population biology. Campos grasslands are under constant influence of disturbance, mostly grazing and fire. However, few studies evaluated the effect of fire on plant population biology of grassland species. Therefore, we aim to analyze the effect of fire on the population biology of four species, from different functional groups and regeneration strategies: Chaptalia runcinata (forb, resprouter, absence of belowground organ), Vernonia flexuosa (forb, resprouter, presence of rhizophore), Eupatorium ligulaefolium (shrub, resprouter, presence of xylopodium) and Heterothalamus psiadioides (shrub, obligate seeder). Seven plots were established in different sites in southern Brazil: frequently burned (FB) and excluded from fire since 6 years (E). All plots were subjected to controlled burns during summer. Before experiments, populations were sampled. Further observations were carried out after 90 and after 360 days of fire experiments. In addition, we counted the number of seedlings and resprouters recruited after fire. Heat shock experiments were conducted with two species (H. psiadioides and V. flexuosa), as well as the study of the bud bank of the following species: E. ligulaefolium and V. flexuosa. The obligate seeder species had all individuals killed by fire and established only after 1 year. Resprouters, however, showed new stems immediately after fire. E. ligulaefolium and V. flexuosa showed only vegetative regeneration from belowground organs and more individuals in excluded sites 1 year after the fire. The bud bank of E. ligulaefolium tended to be larger in excluded sites, whilst V. flexuosa showed an opposite result. High temperatures did not enhance nor kill seeds from both studied species. Vegetative regeneration was the most important strategy for all studied species, except for H. psiadioides, the obligate seeder species. Fire thus, plays an important role on population structure and demography, being also important for plant recruitment.

FIRE INTENSITY AND SEVERITY IN BRAZILIAN CAMPOS GRASSLANDS

Brazilian Campos grasslands are rich in species and the maintenance of its diversity and physiognomy is dependent on disturbance (e.g. fire and grazing) Nevertheless, studies about fire intensity and severity are inexistent. The present paper describes fire parameters, using 14 experimental burn plots in southern Brazil (30 degrees 02` to 30 degrees 04`S, and 51 degrees 06` to 51 degrees 09`W. 311masl). Two sites under different fire histories were chosen: frequently burned and excluded since six years. Experimental burning was performed during summer (2006-2007), when most burning takes place in these grasslands. The following parameters were measured: air temperature and moisture, vegetation height, wind speed, fuel (fine, coarse), fuel moisture, fire temperatures (soil level and at 50cm), ash, residuals, flame freight, fire duration: burning efficiency and fire intensity were later calculated. Fuel load varied from 0.39 to 1.44kg.m(-2). and correlated positively with both fire temperature and fire intensity. Fire temperatures ranged 47 to 537.5 degrees C. being higher in the excluded site Fire intensity was low compared to grassland elsewhere (36 5-319.5kW.m(-1)), differing significantly between sties Fine fuel was the variable that best explained fire intensity. The results on fire intensity and severity in Campos grasslands can be considered a pilot study, since plots were very small. However the data provided can help other researchers to get permission for experimentation using larger plots The results provide support for further studies about the effects of fire on grassland vegetation and for studies involving fire models and fire risk prediction

Association of Human T Lymphotropic Virus 1 Amplification of Periodontitis Severity with Altered Cytokine Expression in Response to a Standard Periodontopathogen Infection

Background. Periodontal diseases (PDs) are infectious diseases in which periodontopathogens trigger chronic inflammatory and immune responses that lead to tissue destruction. Recently, viruses have been implicated in the pathogenesis of PDs. Individuals infected with human T lymphotropic virus 1 (HTLV-1) present with abnormal oral health and a marked increased prevalence of periodontal disease. Methods. In this study, we investigated the patterns of periodontopathogen infection and local inflammatory immune markers in HTLV-1-seropositive individuals with chronic periodontitis (CP/HTLV-1 group) compared with HTLV-1 -seronegative individuals with chronic periodontitis (CP group) and periodontally healthy, HTLV-1 -seronegative individuals (control group). Results. Patients in the CP/HTLV-1 group had significantly higher values of bleeding on probing, mean probing depth, and attachment loss than patients in the CP group. The expression of tumor necrosis factor a and interleukin (IL) 4 was found to be similar in the CP and CP/HTLV-1 groups, whereas IL-12 and IL-17 levels trended toward a higher expression in the CP/HTLV-1 group. A significant increase was seen in the levels of IL-1 beta and interferon gamma in the CP/HTLV-1 group compared with the CP group, whereas expression of the regulatory T cell marker FOXp3 and IL-10 was significantly decreased in the lesions from the CP/HTLV-1 group. Interestingly, similar frequency and/or load of periodontopathogens (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Aggregatibacter actinomycetemcomitans) and frequency of viruses (herpes simplex virus 1, human cytomegalovirus, and Epstein-Barr virus) characteristically associated with PDs were found in the CP/HTLV and CP groups. Conclusions. HTLV-1 may play a critical role in the pathogenesis of periodontal disease through the deregulation of the local cytokine network, resulting in an exacerbated response against a standard periodontopathogen infection.
