The proposal of this article is to present and discuss the methodology applied in the frame of a socio-anthropological research held in Bolivia and Peru on child development and growth. The objectives of the investigation were to study the mother?s perceptions (and those of other related caretakers..

In the countries with a strong muslim immigration, the practice and the organization of Islam represent a national and international politica! stake. The Belgian state, which recognizes and supports the most important cults financially, recognized Islam in 1974. But this cult doesn't still obtain this state support and the questions concerning its organization are more complex than ever. Thelegislation is insufficient and its application almost non-existent. The debates on 'integrism' and hijab have confronted us with the problem of the integrating (...) role of Islam. The Belgian political world seems today to fear the influence of foreign countries on immigrants. All these factors throw light on the history and the present state of the Belgian legislation on the organization of the islamic cult, which this article analyses. (shrink)

Two populations are subdivided into two categories of individuals (hawks and doves). Individuals fight to have access to a resource which is necessary for their survival. Conflicts occur between individuals belonging to the same population and to different populations. We investigate the long term effects of the conflicts on the stability of the community. The modelis a set of ODE's with four variables corresponding to hawk and dove individuals of the two populations. Two time scales are considered. A fast time (...) scale is used to describe frequent encounters and fightings between individuals trying to monopolize the resource. A slow time scale is used for the demography and the long term effects of encounters. We use aggregation methods in order to reduce this model into a system of two ODE's only for the total densities of the two populations which is found to be a classical Lotka-Volterra competition model. We study different cases of proportions of hawks and doves in both populations on the global coexistence and the mutal exclusion of the two populations. Pure dove tactics in both populations are unstable. In cases of mixed hawk and dove in both populations, there is coexistence. Pure dove or mixed hawk-dove tactics in one population can coexist with pure hawks in the other one when the costs of fightings between hawks are large enough. (shrink)

As the result of the complexity inherent in nature, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often deal with models for structured populations in which individuals are classified regarding their age, size, activity or location, and this structuring of the population leads to high dimensional systems. In many instances, the dynamics of the system is controlled by processes whose time scales are very different from (...) each other. Aggregation techniques take advantage of this situation to build a low dimensional reduced system from which behavior we can approximate the dynamics of the complex original system.In this work we extend aggregation techniques to the case of time dependent discrete population models with two time scales where both the fast and the slow processes are allowed to change at their own characteristic time scale, generalizing the results of previous studies. We propose a non-autonomous model with two time scales, construct an aggregated model and give relationship between the variables governing the original and the reduced systems. We also explore how the properties of strong and weak ergodicity, regarding the capacity of the system to forget initial conditions, of the original system can be studied in terms of the reduced system.

We offer an account of empathetic pain that preserves the distinctions among standard pain, contagious pain, empathetic pain, sympathy for pain, and standard pain ascription. Vicarious experiences of both contagious and empathetic pain resemble to some extent experiences of standard pain. But there are also crucial dissimilarities. As neuroscientific results show, standard pain involves a sensorimotor and an affective component. According to our account, contagious pain consists in imagining the former, whereas empathetic pain consists in imagining the latter. We further (...) argue that awareness of another's standard pain is part of empathetic pain, but empathetic awareness of another's standard pain differs from believing that another is in standard pain.

An important Christian philosopher contends that if human energy is channeled in the right direction, "upward and outward," spiritual energy as a motor force in the universe will outdistance technological advance. Index. Translated by Rene Hague. A Helen and Kurt Wolff Book.

How do I know that I am the person who is moving? According to Wittgenstein (1958), the sense of agency involves a primitive notion of the self used as subject, which does not rely on any prior perceptual identification and which is immune to error through misidentification. However, the neuroscience of action and the neuropsychology of schizophrenia show the existence of specific cognitive processes underlying the sense of agency—the ‘‘Who'' system (Georgieff & Jeannerod, 1998) which is disrupted in delusions of (...) control (Frith, 1992). Yet, we have to be careful in the interpretation of such clinical symptoms, which cannot be so easily reduced to deficit of action monitoring or to lack of action awareness. Moreover, we should refine the definition of the sense of agency by distinguishing the sense of initiation and the sense of one's own movements. A conceptual analysis of the empirical data will lead us to establish the taxonomy of the different levels of action representations. (shrink)

The Future of Man is a magnificent introduction to the thoughts and writings of Pierre Teilhard de Chardin, one of the few figures in the history of the Catholic Church to achieve renown as both a scientist and a theologian. Trained as a paleontologist and ordained as a Jesuit priest, Teilhard de Chardin devoted himself to establishing the intimate, interdependent connection between science—particularly the theory of evolution—and the basic tenets of the Christian faith. At the center of his philosophy (...) was the belief that the human species is evolving spiritually, progressing from a simple faith to higher and higher forms of consciousness, including a consciousness of God, and culminating in the ultimate understanding of humankind’s place and purpose in the universe. The Church, which would not condone his philosophical writings, refused to allow their publication during his lifetime. Written over a period of thirty years and presented here in chronological order, the essays cover the wide-ranging interests and inquiries that engaged Teilhard de Chardin throughout his life: intellectual and social evolution; the coming of ultra-humanity; the integral place of faith in God in the advancement of science; and the impact of scientific discoveries on traditional religious dogma. Less formal than The Phenomenon of Man and The Divine Milieu , Teilhard de Chardin’s most renowned works, The Future of Man offers a complete, fully accessible look at the genesis of ideas that continue to reverberate in both the scientific and the religious communities.

Pierre Teilhard De Chardin was one of the most distinguished thinkers and scientists of our time. He fits into no familiar category for he was at once a biologist and a paleontologist of world renown, and also a Jesuit priest. He applied his whole life, his tremendous intellect and his great spiritual faith to building a philosophy that would reconcile Christian theology with the scientific theory of evolution, to relate the facts of religious experience to those of natural science. (...) The Phenomenon of Man, the first of his writings to appear in America, Pierre Teilhard's most important book and contains the quintessence of his thought. When published in France it was the best-selling nonfiction book of the year. (shrink)
