História do ensino primário rural em São Paulo e Santa Catarina (1921-1952): uma abordagem comparada

O livro trata da história do ensino primário rural no Brasil no período de 1921 a 1952, caracterizado por uma significativa expansão do setor. Analisa especialmente o processo de construção das políticas educacionais para o segmento em âmbito nacional e suas repercussões nas reformas de ensino na esfera estadual, exemplificadas pelas de São Paulo e Santa Catarina. Mais do que distinguir o que era próprio e específico de cada uma das regiões estudadas, o trabalho visou também revelar a pluralidade de métodos e os efeitos diversos que as reformas provocaram na educação rural paulista e catarinense. A pesquisa apoiou-se principalmente em documentação. A análise de mensagens de governadores, relatórios, decretos, regulamentações de ensino, revistas de estatísticas, revista brasileira de estudos pedagógicos e obras de época permitiu comparar e relacionar os dados referentes às formas de organização e funcionamento do ensino primário rural, como duração dos cursos, período escolar, programas, métodos, modelos educativos e expansão do ensino. De acordo com a autora, a educação rural, que contrasta em muitos aspectos com a educação urbana, foi um elemento fundamental na expansão da escola pública no Brasil. Mas, segundo ela, estranhamente, é muito pouco estudada no país. De fato, das 5.948 pesquisas de doutorado em Educação abrigadas no banco de teses da Capes no período de 2000 a 2009, somente 165 apresentaram como tema a educação rural, o que equivale a 2,7% da produção. E apenas 1,1% abordava a questão do ponto de vista histórico

Waist circumference in predicting gestational diabetes mellitus

Background: To evaluate waist circumference (WC) measured at 20-24 weeks of gestation as a predictor of gestational diabetes mellitus (GDM).Methods: This cross-sectional study included 240 women at 20-24 weeks of gestation. At enrollment, WC was measured, and both prepregnancy and gestational body mass index (BMI) were estimated. According to the results of 75-g oral glucose tolerance test (OGTT) performed at 24-28 weeks, subjects were allocated into two groups, non-GDM and GDM. WC sensitivity and specificity, and odds ratios (OR) and 95% confidence intervals for BMI and WC were estimated, and a receiver operating characteristics curve was generated.Results: Of the 240 pregnant women enrolled, 31 (13%) had GDM. Prepregnancy BMI (OR = 4.21), gestational BMI (OR = 3.17) and WC at 20-24 weeks (OR = 4.02) correlated with GDM risk. At 20-24 weeks, a WC of 85.5-88.5 cm was the optimal cutoff point for predicting GDM (Sens/Spec balance between 87.1/41.1% and 77.4/56.9%).Conclusion: At 20-24 weeks of gestation, WC values in the range of 86-88 cm showed to be a good performance in predicting GDM.

Experimental Platform for Controlled Faults on Synchronous Generator Armature Windings

An experimental platform that allows application of internal faults on the armature windings of a specially modified synchronous generator in a controlled environment is described. It allows recording and studying current and voltage waveforms of internal fault conditions that may occur in a synchronous generator. Thus, traditional and new protection functions can be tested by using real data, and the transient response of the machine due to internal faults can be analyzed more closely. The hardware-software platform is described in detail, as well as all its control functions. The results can contribute significantly in new protection developments, as well as for educational purposes.

Thalidomide plus dexamethasone as a maintenance therapy after autologous hematopoietic stem cell transplantation improves progression-free survival in multiple myeloma

Despite the good response of stem cell transplant (SCT) in the treatment of multiple myeloma (MM), most patients relapse or do not achieve complete remission, suggesting that additional treatment is needed. We assessed the impact of thalidomide in maintenance after SCT in untreated patients with MM. A hundred and eight patients (<70 years old) were randomized to receive maintenance with dexamethasone (arm A; n = 52) or dexamethasone with thalidomide (arm B; n = 56; 200 mg daily) for 12 months or until disease progression. After a median follow-up of 27 months, an intention to treat analysis showed a 2-year progression-free survival (PFS) of 30% in arm A (95% CI 2238) and 64% in arm B (95% CI 5771; P = 0.002), with median PFS of 19 months and 36 months, respectively. In patients who did not achieve at least a very good partial response, the PFS at 2 years was significantly higher when in use of thalidomide (19 vs. 59%; P = 0.002). Overall survival at 2 years was not significantly improved (70 vs. 85% in arm A and arm B, respectively; P = 0.27). The addition of thalidomide to dexamethasone as maintenance improved the PFS mainly in patients who did not respond to treatment after SCT. Am. J. Hematol. (c) 2012 Wiley Periodicals, Inc.

Towards the stabilization of the low density elements in topology optimization with large deformation

This work addresses the treatment of lower density regions of structures undergoing large deformations during the design process by the topology optimization method (TOM) based on the finite element method. During the design process the nonlinear elastic behavior of the structure is based on exact kinematics. The material model applied in the TOM is based on the solid isotropic microstructure with penalization approach. No void elements are deleted and all internal forces of the nodes surrounding the void elements are considered during the nonlinear equilibrium solution. The distribution of design variables is solved through the method of moving asymptotes, in which the sensitivity of the objective function is obtained directly. In addition, a continuation function and a nonlinear projection function are invoked to obtain a checkerboard free and mesh independent design. 2D examples with both plane strain and plane stress conditions hypothesis are presented and compared. The problem of instability is overcome by adopting a polyconvex constitutive model in conjunction with a suggested relaxation function to stabilize the excessive distorted elements. The exact tangent stiffness matrix is used. The optimal topology results are compared to the results obtained by using the classical Saint Venant–Kirchhoff constitutive law, and strong differences are found.

Democracy Reconsidered : Britain, France, Sweden, and the EU

The purpose of this thesis is to investigate whether some positions in democratic theory should be adjusted or abandoned in view of internationalisation; and if adjusted, how. More specifically it pursues three different aims: to evaluate various attempts to explain levels of democracy as consequences of internationalisation; to investigate whether the taking into account of internationalisation reveals any reason to reconsider what democracy is or means; and to suggest normative interpretations that cohere with the adjustments of conceptual and explanatory democratic theory made in the course of meeting the other two aims. When empirical methods are used, the scope of the study is restricted to West European parliamentary democracies and their international affairs. More particularly, the focus is on the making of budget policy in Britain, France, and Sweden after the Second World War, and recent budget policy in the European Union. The aspects of democracy empirically analysed are political autonomy, participation, and deliberation. The material considered includes parliamentary debates, official statistics, economic forecasts, elections manifestos, shadow budgets, general election turnouts, regulations of budget decision-making, and staff numbers in government and parliament budgetary divisions. The study reaches the following conclusions among others. (i) The fact that internationalisation increases the divergence between those who make and those who are affected by decisions is not by itself a democratic problem that calls for political reform. (ii) That international organisations may have authorities delegated to them from democratic states is not sufficient to justify them democratically. Democratisation still needs to be undertaken. (iii) The fear that internationalisation dissolves a social trust necessary for political deliberation within nations seems to be unwarranted. If anything, views argued by others in domestic budgetary debate are taken increasingly serious during internationalisation. (iv) The major difficulty with deliberation seems to be its inability to transcend national boundaries. International deliberation at state level has not evolved in response to internationalisation and it is undeveloped in international institutions. (v) Democratic political autonomy diminishes during internationalisation with regard to income redistribution and policy areas taken over by international organisations, but it seems to increase in public spending. (vi) In the area of budget policy-making there are no signs that governments gain power at the expense of parliaments during internationalisation. (vii) To identify crucial democratic issues in a time of internationalisation and to make room for theoretical virtues like general applicability and normative fruitfulness, democracy may be defined as a kind of politics where as many as possible decide as much as possible.
