This participatory action research was based on a experience of educational intervention on La Cruz and Bello Oriente (Manrique-Medellin), a marginal zone in the northeastern part of the Commune 3 in Medellin,. Colombia. In this marginal sector, psychosocial problems seem to be associated to limited educational and employment opportunities, domestic violence, illegal armed forces, sexual abuse, social discrimination, and lack of adequate public services, among others. All these are also considered as risk factors for drug dependency. We used a structured interview designed to identify leisure tendencies, use of free time, and tendencies in recreational activities. Data from the interview were triangulated with information collected by observation and in field work and used to build a psycho-pedagogic method based on play and leisure activities. The effects of the use of this educational intervention on the satisfaction of human needs were analyzed in light of the theory of Manfred Max-Neef. Results point out the need for new educational strategies aimed to promote creativity, solidarity, mental, physical and social health, more enthusiasm and motivation and in general, positive attitudes that help prevent drug dependence.

The discussion about the freewill and determinism con- troversy in human behavior is an old one in philosophy and psychology. Despite the fact that discussions on the topic are abundant, some of its implications seem to go unnoticed by psychologists, and especially by students of psychology. We argue that to the same extent that a psychologist is far from the determinism he imposes -a priori and unnecessary-constraints on the development of psychology as a science and profession. As a result, we suggest that the adoption of determinism as a wor- king hypothesis, is an important attitude for the transformation of psychology into a more effective science and profession.

Introduction: A growing biological research field is the cellular senescence, a mechanism that has been associated, under certain circumstances, with malignant transformation. Given the high incidence of ovarian cancer and its main origin from the ovarian surface epithelium, as well as the possibility that an epithelial-mesenchymal transition occurs, we evaluated both the in vitro growth of stromal fibroblasts from the ovarian cortex and their β-galactosidase activity at pH 6, enzyme whose expression is considered as a marker of replicative senescence. Methods: 48 samples of ovarian cortical fibroblasts from donors without a history of cancer were serially cultured until the end of their replicative life. β-galactosidase activity at pH 6 was quantified in each passage by the chemiluminiscent method. As control, we used ovarian epithelial cell cultures from the same donors. The enzyme activity was also evaluated in fibroblasts previously induced to senescence by exposure to hydrogen peroxide. Results: The analysis of the enzyme activity and the replicative capacity taken together showed that the fibroblast cultures reached the senescent state at passages 4-5, as what happened with the control epithelial cells. Fibroblasts induced to senescence showed high variability in the values of enzymatic activity. Conclusions: The similarity between both types of cells in reaching the senescent state deserves to be taken into account in relation to the epithelialmesenchymal transition that has been proposed to explain their behavior in the genesis of cancer arising from ovarian surface epithelium. Low β-galactosidase activity values at pH 6 would suggest possible inactivation of the response pathways to oxidative stress.

The aim of this work is to recover Henri Lefèbvre's methodological contributions for (re)thinking the right to the city, based on the need to know the appropriation of space´s dialectical triad. Empirically, it refers to the urban genesis of Mar del Plata (Argentina), an intermediate Latin American city, and its heterogeneous socio-territorial forms of appropriating inhabitance, or different forms of appropriating goods of use, that lead to think about opening to the transformation of the capitalist social order, and of its urban order, naturalized after the fetischism of private property.
