Human development in an evolutionary perspective

This article presents an evolutionary perspective to the study of human development. Some general assumptions for the study of development are discussed and the principal building blocks of evolutionary psychology are presented. One of them is that there is a universal human nature (which is modulate also by particular conditions of each context) and the cognitive architecture of human beings is the resulted of interactions between genes and environment. Based on those, and other assumptions, directions for the study of child development in an evolutionary stance are discussed, along with the considerations of context and development. Thus, it is assumed there is a relationship between phylogenies and ontogenetic development (the ontogenesis needs to be understood also as a product of evolution), considering the inseparability of biological, socio-cultural, cognitive emotional aspects that constitute this development. It has been concluded that the evolutionary developmental psychology has scientific relevance because it broadens our vision on human development.

Parametric pension reform and the intensive margin of labor supply, evidence from Colombia

We analyze the effect of a parametric reform of the fully-funded pension regime in Colombia on the intensive margin of the labor supply. We take advantage of a threshold defined by law in order to identify the causal effect using a regression discontinuity design. We find that a pension system that increases retirement age and the minimum weeks during which workers must contribute to claim pension benefits causes an increase of around 2 hours on the number of weekly worked hours; this corresponds to 4% of the average number of weekly worked hours or around 14% of a standard deviation of weekly worked hours. The effect is robust to different specifications, polynomial orders and sample sizes.

Num novo paradigma para o Desenvolvimento Humano : «Comunicação e Cultura Inclusivas»

A «comunicação e a cultura inclusivas» constituem o móbil de um amplo desenvolvimento biopsicossocial e humano, numa dimensão de igualdade de circunstâncias e de oportunidades para todos, com lugar e qualidade de vida para todos, independentemente de dificuldades como, por exemplo, sensoriocognitivas, sociocognitivas, sociocomunicacionais, intelectuais, psíquicas, patologias neurogénicas da comunicação. Trata-se de uma «viagem» concisa, «passeando» num paradigma novo para o desenvolvimento humano, o da «educomunicção inclusiva», uma aglutinação conceptual consubstanciada no polinómio «educação+comunicação/TIC+cultura+pedagogia», que é o caminhar livre e seguro, digno e socializante, numa perspetiva ecoevolutiva humana profícua e eticizante da vida.

Global Acceleration and Dispossesion: Regression in the Right to Life and Public Health during Ecuador’s Neoliberal Decades

The present essay’s central argument or hypothesis is, consequently, that the mechanisms accelerating a wealth concentrating and exclusionary economy centred on the benefit and overprotection of big business—with a corresponding plundering of resources that are vital for life—generated forms of loss and regression in the right to healthcare and the dismantling of institutional protections. These are all expressed in indicators from 1990-2005, which point not only to the deterioration of healthcare programs and services but also to the undermining of the general conditions of life (social reproduction) and, in contrast to the reports and predictions of the era’s governments, a stagnation or deterioration in health indicators, especially for those most sensitive to the crisis. The present study’s argument is linked together across distinct chapters. First, we undertake the necessary clarification of the categories central to the understanding of a complex issue; clarifying the concept of health itself and its determinants, emphasizing the necessity of taking on an integral understanding as a fundamental prerequisite to unravelling what documents and reports from this era either leave unsaid or distort. Based on that analysis, we will explain the harmful effects of global economic acceleration, the monopolization and pillaging of strategic healthcare goods; not only those which directly place obstacles on the access to health services, but also those like the destructuration of small economies, linked to the impoverishment and worsening of living modes. Thinking epidemiologically, we intend to show signs of the deterioration of broad collectivities’ ways of life as a result of the mechanisms of acceleration and pillage. We will then collect disparate evidence of the deterioration of human health and ecosystems to, finally, establish the most urgent conclusions about this unfortunate period of our social and medical history.
