PENSAMENTO CONSERVADOR COMO OBSTÁCULO PARA O PLENO DESENVOLVIMENTO NA EDUCAÇÃO

Objetivo: Promover uma reflexão sobre a relação negativa entre o pensamento conservador e o pleno desenvolvimento, objetivo maior da educação. Método: Revisão de literatura e análise crítica. Resultados: a educação, em todos os níveis, no Brasil passou por períodos iniciais onde era elitizada, reservada à nobreza, à realeza e às famílias abastadas, além de servir como instrumento de dominação e controle. Em seguida foi utilizada para interesses políticos e passou por uma ditadura militar de mais de 20 anos. Somente nas últimas décadas conseguiu evoluir o suficiente para chegar à formalização de seu objetivo maior: o pleno desenvolvimento. No entanto para atingir esse objetivo as condições propícias devem estar presentes, assim como alguns requisitos devem ser cumpridos, ao mesmo tempo fatores negativos e impeditivos devem estar eliminados ou controlados. Um desses fatores é o pensamento conservador. A Universidade tem muito a contribuir neste processo, de dentro para fora e em si mesma

Quality issues impacting production planning

Among the various problems affecting production processes, the unpredictability of quality factors is one of the main issues which concern manufacturing enterprises. In make-to-order or in perishable good production systems, the gap between expected and real output quality increases product cost mainly in two different ways: through the costs of extra production or reworks due to the presence of non-compliant items and through the costs originating from inefficient planning and the need of unscheduled machine changeovers. While the first are relatively easy to compute, even ex-ante, the latter are much more difficult to estimate because they depend on several planning variables such as lot size, sequencing, deliveries due dates, etc. This paper specifically addresses this problem in a make-to-order multi-product customized production system; here, the enterprise diversifies each production lot due to the fact that each order is based on the customer specific requirements and it is unique (in example, packaging or textiles and apparel industry). In these contexts, using a rule-of-thumb in overestimating the input size may cause high costs because all the excess production will generate little or no revenues on top of contributing to increasing wastes in general. On the other hand, the underestimation of the lots size is associated to the eventual need of launching a new, typically very small production order, thus a single product will bear twice the changeover costs. With little markups, it may happen that these extra costs can reduce profit to zero. Aim of this paper is to provide a critical analysis of the literature state-of-art while introducing some elements that can help the definition of lot-sizing policies considering poor quality costs

Simplifying the Virtual Safety Stock formula

The paper deepen the analysis into the Virtual Safety Stock theory, which is an approach intended to drastically reduce safety inventory levels exploiting the eventual time lag between the moment when a product is ordered and the time the product needs to be available, while preserving the same performance as a production system that operates with physical safety stock. The original virtual safety stock definition embeds two major problems: a double Gaussian integral in the formulation together with the heritage of the unrealistic assumptions already included in the earliest Hadley and Whitin’s safety stock conception. This paper describes an alternative approach in which the virtual safety stock is defined with a closed-form expression much easier to compute and use in operations management practice

Tikhonov-type iterative regularization methods for ill-posed inverse problems: theoretical aspects and applications

Ill-posed inverse problems arise in many fields of science and engineering. The ill-conditioning and the big dimension make the task of numerically solving this kind of problems very challenging. In this thesis we construct several algorithms for solving ill-posed inverse problems. Starting from the classical Tikhonov regularization method we develop iterative methods that enhance the performances of the originating method. In order to ensure the accuracy of the constructed algorithms we insert a priori knowledge on the exact solution and empower the regularization term. By exploiting the structure of the problem we are also able to achieve fast computation even when the size of the problem becomes very big. We construct algorithms that enforce constraint on the reconstruction, like nonnegativity or flux conservation and exploit enhanced version of the Euclidian norm using a regularization operator and different semi-norms, like the Total Variaton, for the regularization term. For most of the proposed algorithms we provide efficient strategies for the choice of the regularization parameters, which, most of the times, rely on the knowledge of the norm of the noise that corrupts the data. For each method we analyze the theoretical properties in the finite dimensional case or in the more general case of Hilbert spaces. Numerical examples prove the good performances of the algorithms proposed in term of both accuracy and efficiency

Factors associated with interruption of exclusive breastfeeding in low birth weight infants receiving primary care

This study aimed to identify factors associated with interruption of exclusive breastfeeding (EBF) in low birth weight infants receiving primary care. This was a cross-sectional study of 170 infants treated at primary care units on the urban periphery of São Paulo, Brazil. The sample included infants with birth weight ≤ 2,500g (including twins) and 5-minute Apgar ≥ 7, followed until the third month of life, and excluded infants/mothers with complications that would impede EBF, besides infant/maternal deaths. Data were collected from forms completed during consultations and patient records. Prevalence ratios were obtained by Poisson regression. The following factors were associated with interruption of EBF in the first three months of life: maternal age ≤ 18 years; informal employment (protective factor); alcohol intake during pregnancy; < 6 prenatal visits; multiple gestations; birth weight ≤ 2,000g; difficulty breastfeeding in the first month; complaints in breastfeeding during the first month; and use of pacifiers in the first two months. Prior knowledge of these factors can help plan measures and policies to increase EBF rates among low birth weight infants.Visou-se a identificar os fatores associados à interrupção do aleitamento materno exclusivo (AME) de lactentes nascidos com baixo peso assistidos na Atenção Básica. Estudo transversal com 170 lactentes assistidos em unidades básicas de saúde (UBS) da periferia do Município de São Paulo, Brasil. Incluíram-se nascidos com peso ≤ 2.500g (inclusive gemelares), Apgar (5') ≥ 7 e acompanhados até o terceiro mês. Excluíram-se bebê/mãe com alterações que impedissem o AME e óbitos. Coletaram-se os dados utilizando-se formulários preenchidos nas consultas e prontuários. As razões de prevalência foram obtidas por regressão de Poisson. Identificou-se associado à interrupção do AME no terceiro mês: idade materna < 18 anos; vínculo empregatício informal (como fator de proteção); ingestão de álcool na gestação; < 6 consultas no pré-natal; gestação múltipla; peso ao nascer ≤ 2.000g; dificuldade na primeira mamada; queixa sobre a amamentação no primeiro mês; uso de chupeta no primeiro e segundo meses. O conhecimento desses fatores beneficia o planejamento de ações e políticas locais visando ao aumento da amamentação exclusiva dos lactentes nascidos com baixo peso.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Secretaria Estadual de Saúde de São Paulo Instituto de SaúdeUniversidade Federal de São Paulo (UNIFESP) Departamento de Medicina PreventivaSecretaria Municipal de Saúde de São PauloUNIFESP, Depto. de Medicina PreventivaSciEL

From Kongri to Diri ak Djondjon: Slavery, Creolisation and Culinary Genesis in Saint-Domingue and Independent Haiti

This paper discusses the genesis of the cuisine of Haiti which is one of a relatively limited number of cuisines in the world that is genuinely a creole cuisine. This was further cemented by the Haitian Revolution\u27s abrupt ending of slavery and the far-reaching reduction of European influence which allowed its creolised way of life to develop in a setting that was freer of external influence than other Atlantic and Indian Ocean creole societies
