Eleição nas escolas: uma análise do impacto do diretor eleito sobre o desempenho educacional no Estado da Bahia

In Brazil, the selection of school principals is set in a decentralized manner by each state and city, such that processes may vary with time for a specific locality. In the state of Bahia, school principals were appointed by a higher political hierarchy until 2008, when schools under state administration started selecting principals by elections. The main goal of this work is to evaluate whether changing this specific rule affected students proficiency levels. This is achieved by using a panel data and difference-in-differences approachs that compares state schools (treatment group) to city schools (control group) that did not face a selection rule change and thus kept having their principals politically appointed. The databases used are Prova Brasil 2007, 2009 and 2011, the first one prior and the other two former to the policy change. Our results suggest that students attending schools with principals that are selected and elected have slightly lower mean proficiency levels both in mathematics and in portuguese exams than those attending schools with appointed principals. This result, according to the literature, could be related to perverse effects of selecting school administrators by vote, such as corporatism, clientelism and politicization of the school environment

Care cost for pregnant and parturient women with diabetes and mild hyperglycemia

OBJETIVO: Comparar custos de hospitalização e de atenção ambulatorial em gestantes/parturientes diabéticas e com hiperglicemia leve. MÉTODOS: Estudo observacional, prospectivo, quantitativo descritivo realizado em centro de diabete perinatal em Botucatu, SP, entre 2007 e 2008. Foram estimados os custos por absorção diretos e indiretos disponíveis na instituição e os custos específicos para a doença (medicamentos e exames). As 30 gestantes diabéticas tratadas com dieta foram acompanhadas em ambulatório e 20 tratadas com dieta mais insulina foram hospitalizadas. RESULTADOS: O custo da doença diabete (para a assistência pré-natal e parto) foi de US$ 3,311.84 para as gestantes hospitalizadas e de US$ 1,366.04 para as acompanhadas em ambulatório. CONCLUSÕES: Os custos diretos e indiretos e o custo total da assistência pré-natal foram mais elevados nas gestantes diabéticas hospitalizadas enquanto os custos da assistência ao parto e hospitalização para parto e puerpério foram semelhantes. Os custos da assistência pré-natal como no parto/puerpério foram superiores aos valores pagos pelo Sistema Único de Saúde.

An assessment of the economic impact of climate change on the health sector In Jamaica

Climate change is a naturally occurring phenomenon in which the earth‘s climate goes through cycles of warming and cooling; these changes usually take place incrementally over millennia. Over the past century, there has been an anomalous increase in global temperature, giving rise to accelerated climate change. It is widely accepted that greenhouse gas emissions from human activities such as industries have contributed significantly to the increase in global temperatures. The existence and survival of all living organisms is predicated on the ability of the environment in which they live not only to provide conditions for their basic needs but also conditions suitable for growth and reproduction. Unabated climate change threatens the existence of biophysical and ecological systems on a planetary scale. The present study aims to examine the economic impact of climate change on health in Jamaica over the period 2011-2050. To this end, three disease conditions with known climate sensitivity and importance to Jamaican public health were modelled. These were: dengue fever, leptospirosis and gastroenteritis in children under age 5. Historical prevalence data on these diseases were obtained from the Ministry of Health Jamaica, the Caribbean Epidemiology Centre, the Climate Studies Group Mona, University of the West Indies Mona campus, and the Meteorological Service of Jamaica. Data obtained spanned a twelve-year period of 1995-2007. Monthly data were obtained for dengue and gastroenteritis, while for leptospirosis, the annual number of cases for 1995-2005 was utilized. The two SRES emission scenarios chosen were A2 and B2 using the European Centre Hamburg Model (ECHAM) global climate model to predict climate variables for these scenarios. A business as usual (BAU) scenario was developed using historical disease data for the period 2000-2009 (dengue fever and gastroenteritis) and 1995-2005 (leptospirosis) as the reference decades for the respective diseases. The BAU scenario examined the occurrence of the diseases in the absence of climate change. It assumed that the disease trend would remain unchanged over the projected period and the number of cases of disease for each decade would be the same as the reference decade. The model used in the present study utilized predictive empirical statistical modelling to extrapolate the climate/disease relationship in time, to estimate the number of climate change-related cases under future climate change scenarios. The study used a Poisson regression model that considered seasonality and lag effects to determine the best-fit model in relation to the diseases under consideration. Zhang and others (2008), in their review of climate change and the transmission of vector-borne diseases, found that: ―Besides climatic variables, few of them have included other factors that can affect the transmission of vector-borne disease….‖ (Zhang 2008) Water, sanitation and health expenditure are key determinants of health. In the draft of the second communication to IPCC, Jamaica noted the vulnerability of public health to climate change, including sanitation and access to water (MSJ/UNDP, 2009). Sanitation, which in its broadest context includes the removal of waste (excreta, solid, or other hazardous waste), is a predictor of vector-borne diseases (e.g. dengue fever), diarrhoeal diseases (such as gastroenteritis) and zoonoses (such as leptospirosis). In conceptualizing the model, an attempt was made to include non-climate predictors of these climate-sensitive diseases. The importance of sanitation and water access to the control of dengue, gastroenteritis and leptospirosis were included in the Poisson regression model. The Poisson regression model obtained was then used to predict the number of disease cases into the future (2011-2050) for each emission scenario. After projecting the number of cases, the cost associated with each scenario was calculated using four cost components. 1. Treatment cost morbidity estimate. The treatment cost for the number of cases was calculated using reference values found in the literature for each condition. The figures were derived from studies of the cost of treatment and represent ambulatory and non-fatal hospitalized care for dengue fever and gastroenteritis. Due to the paucity of published literature on the health care cost associated with leptospirosis, only the cost of diagnosis and antibiotic therapy were included in the calculation. 2. Mortality estimates. Mortality estimates are recorded as case fatality rates. Where local data were available, these were utilized. Where these were unavailable, appropriate reference values from the literature were used. 3. Productivity loss. Productivity loss was calculated using a human capital approach, by multiplying the expected number of productive days lost by the caregiver and/or the infected person, by GDP per capita per day (US$ 14) at 2008 GDP using 2008 US$ exchange rates. 4. No-option cost. The no-option cost refers to adaptation strategies for the control of dengue fever which are ongoing and already a part of the core functions of the Vector Control Division of the Ministry of Health, Jamaica. An estimated US$ 2.1 million is utilized each year in conducting activities to prevent the post-hurricane spread of vector borne diseases and diarrhoea. The cost includes public education, fogging, laboratory support, larvicidal activities and surveillance. This no-option cost was converted to per capita estimates, using population estimates for Jamaica up to 2050 obtained from the Statistical Institute of Jamaica (STATIN, 2006) and the assumption of one expected major hurricane per decade. During the decade 2000-2009, Jamaica had an average inflation of 10.4% (CIA Fact book, last updated May 2011). This average decadal inflation rate was applied to the no-option cost, which was inflated by 10% for each successive decade to adjust for changes in inflation over time.

Influência do ambiente de nidificação sobre a taxa de eclosão, a duração da incubação e a determinação sexual em Podocnemis (Reptilia, Podocnemididae) no Tabuleiro do Embaubal rio Xingu, Pará

Nos quelônios, as características do ambiente de nidificação têm forte influência sobre a temperatura de incubação dos ovos e, consequentemente, sobre o sucesso reprodutivo. Foram investigados o efeito do ambiente de nidificação sobre a taxa de eclosão, a duração de incubação e a determinação sexual dos filhotes de Podocnemis expansa, Podocnemis unifilis e Podocnemis sextuberculata no Tabuleiro do Embaubal, rio Xingu, estado do Pará, Brasil, em 2007, 2008 e 2010. As praias foram monitoradas entre setembro e janeiro, com o acompanhamento dos ninhos marcados desde o dia de postura, em cada ciclo reprodutivo. As seguintes variáveis foram mensuradas: dia da desova, a profundidade final, a altura do ninho em relação ao nível da água no dia da desova a granulometria e a temperatura de incubação. A taxa de eclosão diferiu entre os anos para as três espécies. A duração de incubação variou entre anos apenas para P. sextuberculata. A razão sexual de P. expansa em 2007 foi 0.08 e em 2008 e 2010 todos os filhotes produzidos foram fêmeas. Para P. sextuberculata a razão sexual em 2007 foi 0.34, e em 2008 e 2010 foi 0.06. A razão sexual de P. unifilis em 2007 foi de 0.41, 0.65 em 2008 e 0.02 em 2010. Todas estas diferenças foram estatisticamente significativas. A altura do ninho com relação ao nível do rio apresentou correlação positiva com a taxa de eclosão das três espécies em 2008 e uma relação negativa com a taxa de eclosão de P. sextuberculata em 2010. O número de dias após o início das desovas influenciou a duração de incubação de P. sextuberculata e P. unifilis em 2008. A temperatura média, o número de horas/grau acima de 32°C e o tamanho do sedimento influenciou a razão sexual de P. expansa. Os resultados atestam para a variação no sucesso de eclosão, no desenvolvimento embrionário e na proporção sexual produzida entre os anos. Ainda, observou-se que a influência de variáveis microclimáticas dos sítios selecionados para desova, embora influenciem nas características térmicas e nas variáveis de interesse, podem variar de ano para outro. Recomenda-se o monitoramento continuado dos referidos parâmetros nas principais áreas onde se investe na proteção de sítios reprodutivos de quelônios.

Programa Minha Casa Minha Vida: estratégia no enfrentamento da crise de 2008

This work aims to present an analysis of the Minha Casa Minha Vida, proposed by Lula's government in 2009, highlighting their main impacts for the country in the period following the international financial crisis of 2008, in addition to demonstrating the perception of different inserted agents in context. We argue that the Program implementation was a strategy for the country to overcome the crisis, moving the economy to stimulate consumption, investment and job creation. This work also analyzes the Lula government, responsible for program implementation, and seeks to show its characteristic points that led to the success of the Minha Casa Minha Vida. Finally, we demonstrate that the 2008 crisis has a side still little explored, that goes beyond the economic data that generated and can be regarded as the mainstream economic thinking crisis

Immunohistochemical expression of Rho GTPases in ameloblastomas

Rho GTPases are proteins that regulate cell cycle, shape, polarization, invasion, migration, and apoptosis, which are important characteristics of normal and neoplastic cells. Rho GTPases expression has been reported in normal tooth germ and several pathologies; however, it has not been evaluated in ameloblastomas. The aim of this study was to analyze the expression and distribution of RhoA, RhoB, Rac1, and Cdc42 Rho GTPases in solid and unicystic ameloblastomas. Three-micrometer sections from paraffin- embedded specimens were evaluated by using an avidin- biotin immunohistochemical method with antibodies against the proteins mentioned above. RhoA and RhoB staining was observed in a high number of cells (P < 0.05) and greater intensity in non-polarized ones. Rac1 was not observed, andCdc42 didnot showany statistical differences between the number of non-polarized and basal positive cells (P > 0.05). Upon comparing the studied ameloblastomas, a higher number of positive cells in the unicystic variant was observed than that in the solid one (P < 0,05). The results obtained suggest that theseGTPases could play a role in the ameloblastoma neoplastic epithelial cell phenotype determination (polarized or non-polarized), as well as in variant (solid or unicystic) and subtype (follicular or plexiform) determination. Furthermore, they could participate in solid ameloblastoma invasion mechanisms. J Oral Pathol Med (2012) 41: 400-407
