Planejamento estratégico e o controle da gestão pública: Desenvolvimento da ação de controle da gestão dos recursos públicos

Esta dissertação procura analisar o planejamento estratégico e a evolução do pensamento estratégico, objetivando identificar a possibilidade de adequação da utilização de suas técnicas, para contribuir no desenvolvimento da metodologia empregada no controle da gestão dos recursos públicos. Com esse propósito, a pesquisa bibliográfica é centrada no estudo do referencial teórico, e enfatiza a investigação das práticas e dos fenômenos organizadonais à luz da teoria da gestão estratégica. Nesse sentido, também é apresentada a análise dos resultados da pesquisa de campo, onde fica caracterizado a carência de estudo, pesquisa e desenvolvimento das práticas de controle; retratando a ausência de um pensamento estratégico voltado para o desenvolvimento dessa poUtica pública. As reflexões sobre as observaçôes colhidas no estudo, levaram à conclusão da necessidade fundamental da utilização do pensamento estratégico e da gestão estratégica, como um exercfcio contínuo de aperfeiçoamento da metodologia de ação de controle da gestão dos recursos públicos, voltada ao melhor cumprimento da missão institucional.

Affirmative action and interracial friendships

In two recent cases involving the University of Michigan, the Supreme Court examined whether race should be allowed to play an explicit role in the admission decisions of schools. The primary argument in these court cases and others has been that racial diversity strengthens the quality of education ofered to all students. Underlying this argument is the notion that educational benefits arise if interactions between students of different races improve preparation for life after college by, among other things, fostering mutual understanding and correcting misperceptions. A comprehensive study of this issue would ideally examine two conditions: first, whether students actually have incorrect perceptions about their friendship compatibility with students of other races at the time of college entrance; second, if misperceptions exist, whether diversity on campus is effective in changing students' beliefs about individuals of different races. In this paper we provide, to the best of our knowledge, the first direct evidence about both conditions by taking advantage of unique new data that was collected specifically for this purpose.

Hemodiálise convencional e de alta eficiência e alto fluxo: estudo comparativo

Controvérsias existem sobre os benefícios da hemodiálise de alto fluxo e alta eficiência em relação a hemodiálise convencional. Este estudo compara, através de parâmetros clínicos, laboratoriais, avaliação do sistema nervoso periférico e autônomo, os pacientes em hemodiálise convencional(HDC) e, após, em hemodiálise de alto fluxo e alta eficiência(HDAF), usando os mesmos parâmetros da cinética da uréia, por um período de tempo de 4-8 meses em cada modalidade de tratamento hemodialitico. O sistema nervoso periférico foi avaliado através da miografia e da neurografia de membros superiores e inferiores. O estudo da variabilidade da freqüência cardíaca, através de seis índices no domínio do tempo, foi usado para avaliar o sistema nervoso autônomo nestes pacientes. Não houve diferença quanto às manifestações intradialíticas nos dois tipos de hemodiálise e nem alteração dos níveis tensionais no período de acompanhamento. Na avaliação laboratorial, verificou-se diferença estatisticamente significativa entre a HDC e HDAF nos seguintes parâmetros: creatinina(9,6mg/dl±2,3x10,9mg/dl±2,0;p<0,01),reserva alcalina (16,5mEq/l±2,5x18,2mEq/l±2,7; p<0,05), ácido úrico(6,3mg/dl±1,3x7,1mg/dl±1,64;p<0,01), fósforo(6,4mg/dl±1,3x7,2mg/dl ±1,4;p<0,01) e albumina(4,1mg/ml±0,5x3,8mg/ml±0,27;p<0,01). Observou-se melhora significativa da velocidade de condução sensitiva do nervo ulnar na HDAF(40,72m/s±5,11x48,01m/s±7,7;p<0,05). Houve redução significativa da variabilidade da freqüência cardíaca nos pacientes urêmicos em hemodiálise, comparativamente ao grupo de indivíduos normais. Concluiu-se que não houve diferença significativa nos parâmetros clínicos entre os dois tipos de hemodiálise. Observou-se redução significativa da albumina na HDAF, bem como aumento significativo da creatinina, reserva alcalina, fósforo e ácido úrico. Houve melhora significativa da velocidade de condução sensitiva do nervo ulnar nos pacientes em HDAF. Os pacientes em hemodiálise apresentam deterioração significativa do Sistema Nervoso Autônomo comparativamente ao grupo controle.

Alocação de recursos: nível ótimo de diversificação intraclasse entre fundos de investimentos abertos no Brasil

Apesar da diversidade de suas estratégias, os retornos dos fundos de investimentos multimercado geralmente exibem correlação positiva com índices de bolsa. Por outro lado, fundos de categorias distintas tendem a ser menos correlacionados entre si se comparados a fundos de mesma categoria. A ideia de diversificação entre fundos de baixa correlação é discutida recorrentemente pela literatura. Na prática, porém, poucos alocadores de portfólios otimizam suas carteiras através das linhas de Markowitz (1953) por exemplo. O objetivo deste estudo é buscar identificar o ponto ótimo de diversificação de ativos (fundos de investimentos) dentro de uma mesma categoria. Como metodologia, buscaremos a minimização do risco idiossincrático dos fundos de investimentos através de simulações com outros fundos de mesma categoria. O estudo contém análises para a escolha do número ideal de ativos em um dado portfólio. Esses resultados beneficiariam, principalmente, o processo decisório das empresas de Wealth Managements, das Consultorias de Investimentos e dos Private Bankers.

Preferência alimentar e identificação das principais fontes de repasto sanguíneo de fêmeas Lutzomyia (Diptera: Psychodidae) em áreas endêmicas para leishmaniose visceral na grande Natal

Leishmaniasis are endemic diseases wild spread in the New and Old World, caused by the flagelated protozoan Leishmania. In the New World, the distribution of different forms of leishmaniasis is mostly in tropical regions. In the State of Rio Grande do Norte, Northeast Brazil, 85% of the captured sand flies fauna is Lutzomyia longipalpis. The distribution of the sand fly vector in the state overlaps with the disease distribution, where the presence of sand flies is associated with presence of animals shelters. The aim of this study was to analyse the blood meal preference of sand flies vector from the genus Lutzomyia spp. in laboratory conditions, to verify the vector life cicle at different temperatures sets and to identify the main blood meal source in endemic areas for visceral leishmaniasis (VL) at peri-urban regions of Natal. Sand flies samples were collected from the municipalities of São Gonçalo do Amarante and Nísia Floresta where female sand flies were grouped for the colony maintenance in the laboratory and for the analysis of the preferred source of sand fly blood meal in natural environment. The prevalence of blood meal preference and oviposition for the females sand flies was 97% for Cavia porcellus with oviposition of 19 eggs/female; 97% for Eqqus caballus with 19 eggs/female; 98% for human blood with 14 eggs/female; 71.3% for Didelphis albiventris with 8.4 eggs/female; 73% for Gallus gallus with 14 eggs/female; 86% for Canis familiaris with 10.3 eggs/female; 81.4% for Galea spixii with 26 eggs/female; 36% for Callithrix jachus with 15 eggs/female; 42.8% for Monodelphis domestica with 0% of oviposition. Female sand flies did not take a blood meal from Felis catus. Sand flies life cycle ranged from 32-40 days, with 21-50 oviposition rates approximately. This study also showed that at 32°C the life cycle had 31 days, at 28° C it had 50 days and at 22°C it increased to 79 days. Adjusting the temperature to 35°C the eggs did not hatch, thus blocking the life cycle. A total of 1540 sand flies were captured, among them, 1.310 were male and 230 were female. Whereas 86% of the sand flies captured were Lu. longipalpis as compared to 10.5% for Lu. evandroi and, 3.2% for L. lenti and 0.3% for Lu whitmani. The ratio between female and male sandfly was approximately 6 males to 1 female. In Nísia Floresta, 50.7% of the collected females took their blood meal from armadillo, 12.8% from human. Among the female sand flies captured in São Gonçalo do Amarante, 80 of them were tested for the Leishmania KDNA infectivity where 5% of them were infected with Leishmania chagasi. Female Lutzomyia spp. showed to have an opportunistic blood meal characteristic. The behavioral parameters seem to have a higher influence in the oviposition when compared to the level of total proteins detected in the host s bloodstream. A higher Lu. longipalpis life cycle viability was observed at 28°C. The increase of temperature dropped the life cycle time, which means that the life cycle is modified by temperature range, source of blood meal and humidity. Lu longipalpis was the most specie found in the inner and peridomiciliar environment. In Nísia Floresta, armadillos were the main source of blood meal for Lutzomyia spp. At São Gonçalo do Amarante, humans were the main source of blood meal due to CDC nets placed inside their houses

Purificação e caracterização parcial de duas n-acetil-B-hexosaminidases do equinoderma marinho echinometra lucunter

Two b-N-acetylhexosaminidases (F11 e F15) were purified from Echinometra lucunter gonads extracts. The purified enzymes were obtained using ammonium sulfate fractionation, followed by gel filtration chromatographies (Sephacryl S-200, Sephadex G-75 and Sephacryl S-200). The F11 fraction was purified 192.47 -fold with a 28.5% yield, and F15 fraction 85.41 -fold with a 32.3% yield. The molecular weights of the fractions were 116 kDa for F11 and 42 kDa for F15 using SDS-PAGE. In Sephacryl S-200, F15 was 84 kDa, indicating that it is a dimeric protein. When p-nitrophenyl-β-D-glycosaminide was used as substrate, we determined an apparent Km of 0.257 mM and Vmax of 0.704 for F11 and for F15 the Km was 0.235 mM and Vmax of 0.9 mM of product liberated by hour. Both enzymes have optimum pH and temperature respectively at 5.0 and 45 °C. The enzymes showed inhibition by silver nitrate, while the glucuronic acid was a potent activator. The high inhibition of F15 by N-etylmaleimide indicates that sulphydril groups are involved in the catalysis of synthetic substrate

Fatores de risco individuais e familiares no desenvolvimento da pré-eclâmpia

Preeclampsia is a spectral disease, with different clinical forms which can evolve with severe multisystemic complications. This present study aimed to determine the risk factors associated with preeclampsia (PE); to validate the existence of aggregation of hypertensive disease in families of women with preeclampsia and verify the existence of association between polymorphisms in the VEGF gene and level of VEGF and its soluble receptor (sFlt1). A case-control study was performed (n = 851). Genotyping of VEGF was performed and serum levels of VEGF and sFlt1 were measured by ELISA. It was observed that 38% of mothers (173, 455) of a case of preeclampsia and 30.8% (78 of 361) of controls had history of hypertension (p <0.0001). Similarly, when examining the history of maternal preeclampsia, we observed that 14.6% (48 of 328) of mothers of women with preeclampsia and 9.6% (12 of 294) of mothers of controls had a history of preeclampsia (p = 0.0001). As for maternal history of preeclampsia, we found that 5.1% (15 of 295) of cases and 3.6% (7 of 314) of controls had a history of preeclampsia (p = 0.0568). Sisters of women with preeclampsia also had a history of hypertensive disease in 9% (41 of 455) versus 6.6% (13 of 361), p = 0.002. Similarly when examining the history of preeclampsia in sisters, it was observed that 22.7% (57 of 251) of a sister of case versus 11.4% (26 of 228) of controls had a history of preeclampsia (P = 0.0011). We observed a decrease in free VEGF in the serum of patients (P <0.05) and increased soluble VEGF receptor. There was no association between polymorphisms in the VEGF gene and preeclampsia. The data obtained in this work validate that hypertensive disease in mothers and sisters with preeclampsia are risk factors for preeclampsia. The risk of illness in the family is higher according to disease severity. High incidence of preeclampsia can be assumed by the high incidence of this disease among the controls. Significant differences between the frequency of preeclampsia in mothers of cases and controls indicate familial factors. Work is being conducted with the to eventually perform genome wide association studies to identify susceptibility loci

Influence of the season of year, stage of lactation and milking time on the chloride content in bovine milk

From January to October 1995, chloride content determinations were accomplished in 2,218 samples of milk collected from 67 quarters of 17 lactating cows, in initial, middle and final stages of lactation, in the morning and afternoon milking. The highest means of chloride contents were observed among the milk samples collected in the final stage of lactation (0,203 gC1/100ml), in the summer (0,212 gC1/100ml) and in the morning milking (0,189 g C1/100ml). The differences observed between the chloride contents in the samples obtained in the different stages of lactation and the seasons of the year were statistically significant (P<0.0001). The gratest occornce of chloride at rates superior to 0.22 gC1100ml was observed in the final stge of lactation (31.4%), summer (44.2%) and after the morning milking (27.8%). These results evidentiate the influence of physiological and external factors (stage of lactation and season of the year) on the concentration of chloride of milk.
