postulamos, a partir de Spinoza, que un poema es -entre otras cosas- el registro verbal de un proceso afectivo, cabe extraer interesantes conclusiones sobre el valor gnoseológico de la poesía. El análisis desde estas premisas de la obra de Walt Whitman muestra cómo la apertura a los afectos es una condición del conocimiento: la maximización de los afectos favorables y la comprensión de sus causas adecuadas permite al poeta no sólo expresar pasivamente un balance sino generar activamente afectos y por (...) tanto ideas; el poema aparece así como instrumento de conocimiento y de transformación.

Reseña de _En defensa de la razón. Contribución a la crítica del posmodernismo_ de Francisco Erice Sebares.

BackgroundIn their professional practice, teachers can exert a strong influence on students, promoting healthy habits for life through the example of their own lifestyle. The aim of this study was to compare sports habits and attitudes in Physical Activity and Sports Education students at the universities of León and Mostaganem.MethodsWe administered the “Motivations and Attitudes Toward Physical Activity and Sports” questionnaire to 125 Algerian university students from the Institute for Physical Education and Sport and 122 Spanish university students from the (...) Faculty of Physical Activity and Sport Science.ResultsChi-square tests showed significant differences with a large effect size in perceptions of sport and satisfaction with participation.ConclusionThe students from Mostaganem and Leon show many similarities, such as the number of female students in physical education and sport is quite small compared to male students. Both consider that universities should improve sports facilities to promote good practice. The practice of sports by our university students is far superior to that of students with other degrees, suggesting that they will set a good example of healthy habits once they enter their profession. Nevertheless, the participation of female Algerian students in sport was lower than that of Spanish students, and students at León showed more intrinsic motivation for participating in sport than their counterparts at Mostaganem.

Human pluripotent stem cells (hPSCs) have the potential to fundamentally change the way that we go about treating and understanding human disease. Despite this extraordinary potential, these cells also have an innate capability to form tumors in immunocompromised individuals when they are introduced in their pluripotent state. Although current therapeutic strategies involve transplantation of only differentiated hPSC derivatives, there is still a concern that transplanted cell populations could contain a small percentage of cells that are not fully differentiated. In addition, (...) these cells have been frequently reported to acquire genetic alterations that, in some cases, are associated with certain types of human cancers. Here, we try to separate the panic from reality and rationally evaluate the true tumorigenic potential of these cells. We also discuss a recent study examining the effect of culture conditions on the genetic integrity of hPSCs. Finally, we present a set of sensible guidelines for minimizing the tumorigenic potential of hPSC‐derived cells. © 2016 The Authors. Inside the Cell published by Wiley Periodicals, Inc. (shrink)
