Drug dependence, mental impairment and education

This study aimed to evaluate the mental conditions of cocaine-dependent individuals and school commitment/attachment. We evaluated 50 patients referred to the psychiatry emergency room due to mental disorders from chemical dependence. After clinical diagnosis, clinical interview, Hospital Anxiety and Depression Scale, Hamilton Scale for Depression and Brief Psychiatric Rating Scale were applied. The Spearman and Mann-Whitney nonparametric tests, as well as the t-Student test were utilized for statistical analysis.. The accepted significance value was 0.05. All subjects had used cocaine or crack and other substances. Only 13 (26%) did not drop out of school (group 1). Regarding the other 37 (74%), irregular class attendance , successive failures and definitive school drop out rates (group 2) were verified. These subjects presented an early substance use when compared with those which did not drop out of school (p=0.0001). Patients with an early substance use presented higher school dropout rates than those with a later initiation to substance use. Psychopathological phenomena were frequent in both groups.

Interactive DC-DC converters tools for instant design and education

This paper deals with the usage of interactive simulations tools to serve as an oriented design tool for the lectures and laboratory experiments in the power electronics courses. A dynamic and interactive visualization of simulations for idealized converters in steady state are provided by the proposed educational tools, allowing students to acquire qualification in non-isolated DC-DC converters, without previous circuitry knowledge, either without the usage of sophisticated simulation packages. The interaction with proposed simulation tools can be accomplished by student using direct or graphic mode. In direct mode the parameters related with the design of converter can be inserted simply editing default values presented in textboxes, while in the graphic mode students interact indirectly with design information by manipulating visual widgets. In order to corroborate the proposed interactive simulation tools, comparisons of results from buck-boost and boost converters on proposed tools and a well-known simulator package with those on experimental evaluation from laboratory classes were presented. © 2009 IEEE.

Ética, preconceito e educação: características das publicações em periódicos nacionais de educação, filosofia e psicologia entre 1970 e 2003

Apresenta um estudo bibliográfico referente ao tema ética e preconceito no âmbito da educação escolar em periódicos nacionais das áreas de educação, psicologia e filosofia a partir da década de 1970 até o ano de 2003. No total, foram categorizados e analisados 570 textos. Constatamos que, especialmente, nas três últimas décadas, houve uma preocupação, por parte dos pesquisadores, com questões éticas e a problemática da diversidade e suas relações com a educação escolar. Percebemos, também, que algumas revistas científicas se destacaram por apresentar um maior número de produções científicas publicadas com o tema e no período que compreende este estudo. Além disso, a maioria dos trabalhos realizou estudos teóricos e pesquisas bibliográficas em detrimento às pesquisas empíricas. Foi elaborado um índice dos textos pesquisados que, juntamente com o material coletado, funcionará como banco de dados para pesquisadores, ligados a diversas áreas do conhecimento, que possuam interesse em estudar o tema ética e preconceito e seus diversos subtemas.

O preconceito como obstáculo à educação sexual: reflexões a partir de uma perspectiva ética

This paper developed a reflection about problems related to the establishment of ethical principles that guide the sexual education aiming at emancipation. Our theoretical framework is the Critical Theory of Society, in particular texts by T. W. Adorno on training, prejudice and education. It is understood that numerous difficulties are related to the achievement of an emancipatory education, and such difficulties are even greater when it comes to sex education since it is an issue that still raises irrational fears on educators, and is absent from the training they received. Following Adorno, it is understood that the current formation favors the development of subjects inclined to prejudice, and that an emancipatory sexual education involves a critique to the conditions under which such formation occurs and, at the same time, a continuous reflection about the relations between the desires and the social possibilities of their realization.

Mathematics education and democracy

In this paper, we investigate the relationship between mathematics education and the notions of education for all/democracy. In order to proceed with our analysis, we present Marx's concept of commodity and Jean Baudrillard's concept of sign value as a theoretical reference in the discussion of how knowledge has become a universal need in today's society and ideology. After, we engage in showing mathematics education's historical and epistemological grip to this ideology. We claim that mathematics education appears in the time period that English becomes an international language and the notion of international seems to be a key constructor in the constitution of that ideology. Here, we draw from Derrida's famous saying that there is nothing beyond the text. We conclude that a critique to modern society and education has been developed from an idealistic concept of democracy. © FIZ Karlsruhe 2009.

Paradigmas, valores e educação

O texto levanta os perfis epistemológico e socianalítico da questão paradigmática. Mauss evidenciara o moule affectif das noções científicas de força e causa. Posteriormente Baudouin falaria na indução arquetípica das noções e a antropologia do imaginário de Durand concluiria pela indução arquetipal do conceito pela imagem. Chegava-se, assim, ao desvendamento do substrato inconsciente das ideações, de um substrato regido pela catexis vetorializada, traduzindo-se nos valores como cerne das ideações. É o famoso a priori emotivo. Portanto, no texto, questionam-se dois mitos, esteios da ciência clássica: o mito da objetividade científica e o da neutralidade axiológica. Destaca, assim, a falácia da existência de uma ruptura epistemológica entre ciência e ideologia. A partir daí, as ideações tornam-se ideologias, sobretudo nas ciências do homem e nas ciências da educação que, ademais, tornam-se suporte de uma disfarçada luta ideológica, na qual, num colonialismo cognitivo, as estratégias de conhecimento dissimulam as de preconceito. Entretanto, assumir a realidade desse suporte fantasmanalítico e ideológico propicia uma tarefa educativa salutar: os paradigmas tornam-se fantasias e, nessa relativização crítica, podem ser usados como um campo de objetos transicionais coletivos num ludismo cultural e educativo. No policulturalismo da sociedade contemporânea, o politeísmo de valores de Weber transforma-se num politeísmo epistemológico, regido pelo relativismo ontológico de Feyerabend e por uma ética do pragmatismo. Articulando cultura, organização e educação, a antropologia das organizações educativas e a culturanálise de grupos de Paula Carvalho traduzem as heurísticas dessa dialética transicional.

Limites do ensino de dança na formação do professor de Educação Física

The dance is one of the cultural content of body movement. But it is known, by means of literature and researches, that the training of teachers of Physical Education has submitted this content limits, damaging their future education in schools. This article discusses these limits and their possible solutions, ruled itself for both in literature and analysis on data collected in search of the Masters PEREIRA (2007). In this analysis it was felt that the dance is little in this Fitness because of graduate students have little experience inside and outside the school environment, because many parents, teachers and students have to dance with prejudice, and because do not feel prepared to deal with this content in schools. It appears that this may be due to the hegemony of sports in physical education, and some misunderstandings when you think the goals and content of dance in physical education.

Levels of DNA damage in blood leukocyte samples from non-diabetic and diabetic female rats and their fetuses exposed to air or cigarette smoke

dThe objective of the present study was to evaluate DNA damage level in blood leukocytes from diabetic and non-diabetic female Wistar rats exposed to air or to cigarette smoke, and to correlate the findings with levels of DNA damage detected in blood leukocyte samples from their fetuses. A total of 20 rats were distributed into four experimental groups: non-diabetic (control; G1) and diabetic exposed to filtered air (G2): non-diabetic (G3) and diabetic (G4) exposed to cigarette smoke. Rats placed into whole-body exposure chambers were exposed for 30 min to filtered air (control) or to tobacco smoke generated from 10 cigarettes, twice a day, for 2 months. Diabetes was induced by a pancreatic beta-cytotoxic agent, streptozotocin (40 mg/kg b.w.). At day 21 of pregnancy, each rat was anesthetized and humanely killed to obtain maternal and fetal blood samples for genotoxicity analysis using the alkaline comet assay. G2, G3 and G4 dams presented higher DNA damage values in tail moment and tail length as compared to G1 group. There was a significant positive correlation between DNA damage levels in blood leukocyte samples from G2 and G3 groups (tail moment); G3 and G4 groups (tail length) and G3 group (tail intensity) and their fetuses. Thus, this study showed the association of severe diabetes and tobacco cigarette smoke exposure did not exacerbate levels of maternal and fetal DNA damages related with only diabetes or cigarette smoke exposure. Based on the results obtained and taking into account other published data, maternal diabetes requires rigid clinical control and public health and education campaigns should be increased to encourage individuals, especially pregnant women, to stop smoking.

Psychophysical power functions for apparent area in perceptive, memory, and inference conditions for observers of different age groups

The purpose of this research was to verify the effect of age on the exponent of the power function in Perceptive, Memory, and Inference experimental conditions. In the Memory condition the intervals of 2 min., 8, 24, and 48 hr. and 1 wk. were used between acquisition of information and remembering. For each experimental condition the ages of observers ranged between 17 and 35 years (Group I), 40-55 years (Group II), and 60-77 years (Group III), and education ranged from high school to graduate school. The observers estimated the areas of the Brazilian states using the psychophysical method of magnitude estimation. No significant differences were obtained for Groups I, II, and III for each experimental condition, except in the Memory Condition with the 24-hr. interval. Analysis for experimental conditions and ages showed a significant difference between the Perceptive Condition and each of the others, but no difference between the Inference and Memory Conditions. These results indicated that in the remembering processes there is no loss of information as a function of age. From the small variability in the power function exponents for the three ages, we may assume that age could be related to amount of education of the observers, which suggests study is important.

Social and environmental indexes to determine the impacts of closed neighbourhoods in Brazil

São Paulo State, in Brazil, is getting increasingly crowded, like in other third world countries around the world, so should give great importance to city development. This work considered the phenomenon of closed neighbourhoods (CN) as an important factor to city planning, papers report many impacts of this model of neighbourhoods in other countries, but in Brazil its impacts are not yet well listed in the literature. The aim of this work was to determine indicators to achieve the social and environmental performances and verify their applicability on three different closed neighbourhoods in São Paulo state, Brazil. The indicators were condensed on indexes: water management, waste management, energy and emissions, legal compliance, environment and buildings, risk management, health and education and governance. The preliminary results indicated several social and environmental problems in all indexes. © 2013 WIT Press.
