Educação e ambiguidades da autonomização: para uma pedagogia crítica da promoção do indivíduo autónomo

O presente artigo, confrontando a educação com o desiderato da autonomização, pretende analisar as ambiguidades a que esse confronto dá hoje origem e estabelecer, mediante a explicitação de uma conceção contra-hegemónica de autonomização, as bases e as coordenadas de uma pedagogia crítica da promoção do indivíduo autónomo, que seja simultaneamente humanista, emancipadora e transformadora tanto da realidade do sujeito quanto da realidade do contexto. A estrutura narrativa, em consonância com esse amplo propósito, articula as seguintes dimensões: a educação e a normatividade da autonomização; as ambiguidades da autonomização: sentidos divergentes de fazer educação para a autonomia; e, por fim, o empowerment emancipatório e transformador: vetor da educação enquanto autonomização contra-hegemónica. A conclusão aponta as linhas diretoras da construção de uma pedagogia crítica do indivíduo autónomo, assumida nas vertentes de emancipação individual e transformação social.

Localization of MCT2 at peroxisomes is associated with malignant transformation in prostate cancer

Previous studies on monocarboxylate transporters expression in prostate cancer (PCa) have shown that monocarboxylate transporter 2 (MCT2) was clearly overexpressed in prostate malignant glands, pointing it out as a putative biomarker for PCa. However, its localization and possible role in PCa cells remained unclear. In this study, we demonstrate that MCT2 localizes mainly at peroxisomes in PCa cells and is able to take advantage of the peroxisomal transport machinery by interacting with Pex19. We have also shown an increase in MCT2 expression from non-malignant to malignant cells that was directly correlated with its peroxisomal localization. Upon analysis of the expression of several peroxisomal ß-oxidation proteins in PIN lesions and PCa cells from a large variety of human prostate samples, we suggest that MCT2 presence at peroxisomes is related to an increase in ß -oxidation levels which may be crucial for malignant transformation. Our results present novel evidence that may not only contribute to the study of PCa development mechanisms but also pinpoint novel targets for cancer therapy.

A study of risk-aware program transformation

In the trend towards tolerating hardware unreliability, accuracy is exchanged for cost savings. Running on less reliable machines, functionally correct code becomes risky and one needs to know how risk propagates so as to mitigate it. Risk estimation, however, seems to live outside the average programmer’s technical competence and core practice. In this paper we propose that program design by source-to-source transformation be risk-aware in the sense of making probabilistic faults visible and supporting equational reasoning on the probabilistic behaviour of programs caused by faults. This reasoning is carried out in a linear algebra extension to the standard, `a la Bird-Moor algebra of programming. This paper studies, in particular, the propagation of faults across standard program transformation techniques known as tupling and fusion, enabling the fault of the whole to be expressed in terms of the faults of its parts.

Virtual reality in assessment and treatment of schizophrenia: a systematic review

Objective To conduct a systematic review about the use of virtual reality (VR) for evaluation, treatment and/or rehabilitation of patients with schizophrenia, focused on: areas, fields and objectives; methodological issues; features of the VR used; viability and efficiency of this resource. Methods Searches were performed about schizophrenia and virtual reality in PsycINFO, Academic Search Complete, MEDLINE Complete, CINAHL with Full Text, Web of Science and Business Source Premier databases, using the following keywords: [“schizophrenia”] AND [“virtual reality” OR “serious game”] AND [“treatment” OR “therapy” OR “rehabilitation”]. The search was carried out between November 2013 and June 2014 without using any search limiters. Results A total of 101 papers were identified, and after the application of exclusion criteria, 33 papers remained. The studies analysed focused on the use of VR for the evaluation of cognitive, social, perceptual and sensory skills, and the vast majority were experimental studies, with virtual reality specifically created for them. All the reviewed papers point towards a reliable and safe use of VR for evaluating and treating cognitive and social deficits in patients with schizophrenia, with different results in terms of generalisation, motivation, assertiveness and task participation rate. Some problems were highlighted, such as its high cost and a constant need for software maintenance. Conclusion The studies show that using the virtual reality may streamline traditional evaluation/rehabilitation programmes, allowing to enhance the results achieved, both in the cognitive and in the social field, helping for the legitimisation of this population’s psycho-social inclusion.

Transformacion de Productos Regionales mediante procesos catalíticos. Transformation of Regional products by catalytic processes.

En este proyecto se plantea la posibilidad de aumentar el valor agregado de compuestos abundantes en nuestro país (terpenos y glicerol) mediante reacciones de oxidación y transesterificación, reemplazando los procesos homogéneos existentes por procesos heterogéneos eco-compatibles. Para ello se desarrollarán catalizadores heterogéneos del tipo MCM-41 e hidroxidos de doble capa (HDC) que posean la función activa específica para estas reacciones bajo estudio.El limoneno, principal componente del aceite esencial de limón y los alfa- y beta- pinenos, presentes en el aceite de trementina, son materiales base ampliamente disponibles. Su oxifuncionalización catalítica, mediante reacciones de epoxidación u oxidación alilica, permite producir una gran variedad de productos como fragancias, agroquímicos, medicinas, etc. En tanto, se espera un marcado incremento en la disponibilidad de glicerol, subproducto de la producción de biodiesel. Mediante su transesterificación catalítica heterogénea es posible obtener selectivamente monoésteres, los cuales tienen importantes aplicaciones como emulsionantes o agentes de estabilización en la producción de fármacos, cosméticos y alimentos. El diseño y síntesis de los materiales catalíticos mencionados permitirá la obtención de productos químicos finos por métodos limpios con bajo impacto ambiental, atendiendo a los altos niveles de contaminación ambiental generados por los procesos homogéneos tradicionales.
