According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

Why do some individuals willingly make extreme sacrifices for their group? Whitehouse argues that such willingness stems from a visceral feeling of oneness with the group – identity fusion – that emerges from intense, shared dysphoric experiences or from perceived close kinship with others. Although Whitehouse's argument makes a valuable contribution to understanding extreme sacrifice, factors independent of identity fusion, such as devotion to sacred values, can predict self-sacrifice.

Los valores cristianos son ahora más relevantes debido a que las empresas no se preocupan solo del beneficio. mediante una muestra de 176 empresas de la zona 4 de Ecuador, se ha estudiado la aplicación de los valores de solidaridad, honestidad, humildad y responsabilidad en los procesos productivos y de contratación de personal. El objetivo es averiguar si estos valores son relevantes en la gestión. Como resultado se encontró que existen pocas empresas que tengan en cuenta estos valores declarados como (...) tal. La ausencia de estos valores indica que las empresas deben incorporarlos para tener mayor sostenibilidad y responsabilidad social. (shrink)

In the paper we analyze the educational rationality closely associated with a neoliberal cultural logic that causes various lifestyles which seek only the satisfaction of unreal or symbolic needs where the ideal of education appears as one more among others. Furthermore, we consider educational policies subordinated to an expansive cultural logic of post-industrial capitalism, having as a historical reference the neoliberal turn of the Peruvian educational policy and a symbolic structure deeply established in the psyche of the society transformed by (...) the social pathologies of mercantilism and consumerism. This insight will allow us to propose a socio-philosophical critique of postmodernity. (shrink)

Este artículo realiza un análisis crítico de las respuestas que se han estructurado a nivel jurídico y político para hacer frente a las migraciones climáticas. Resalta la necesidad de incorporar el enfoque étnico-racial en el abordaje de este fenómeno debido a su impacto diferencial sobre los derechos de las personas afrodescendientes e indígenas, en especial en lo relativo al territorio y la propiedad colectiva. Examina, además, las causas estructurales que le subyacen y utiliza ese estudio como base para fijar parámetros (...) que puedan ser tenidos en cuenta en la construcción de futuras políticas internacionales.

Concordancia del entendimiento consigo mismo o identidad del entendimiento con sus objetos son expresiones que definen dos modelos pensamiento de tanta relevancia como los de Kant y Aristóteles. En el seguimiento de ambos modelos podemos contemplar la concepción de la razón, de la ciencia, del ser del hombre y de la relación del hombre con la naturaleza. Marcan, además, dichos modelos largas y significativas épocas de vigencia. Tanto en uno como en el otro, aunque con distinto tono, domina la conciencia (...) de finitud trabada a la aspiración a la trascendencia. Finitud y trascendencia son los términos en los que se define la tarea y el destino de la filosofía. La imposibilidad de que el entendimiento concuerde consigo mismo deriva, en el caso de Aristóteles, hacia la concordancia con los objetos; en el de Kant, a construir la concordancia del entendimiento consigo mismo y a tomarla como una ley subjetiva. La opción kantiana se vuelve para nosotros hoy exigencia de reconciliación con la naturaleza. Es una tarea tanto más urgente cuanto más profunda es la sima que separa al hombre de su lugar natural en medio de las cosas y de los demás. (shrink)

We distinguish two pathways people may follow when they join violent groups: compliance and internalization. Compliance occurs when individuals are coerced to join by powerful influence agents. Internalization occurs when individuals join due to a perceived convergence between the self and the group. We searched for evidence of each of these pathways in field investigations of former members of two renowned terrorist organizations: the Liberation Tigers of Tamil Eelam and Islamist radical groups. Results indicated that ex-fighters joined LTTE for reasons (...) associated with both compliance and internalization but that ex-fighters joined Islamist radical groups primarily for reasons associated with internalization. When compliance occurred, it often took the form of coercion within LTTE but involved charismatic persuasion agents within Islamist groups. This evidence of systematic differences in the reasons why fighters enter violent groups suggests that strategies for preventing radicalization and fostering de-radicalization should be tailored to particular groups.
