El modelo explicativo más contrastado para entender la situación escolar del alumnado de minorías étnicas es el elaborado por el antropólogo John Ogbu y constituye, además, un punto de referencia central en los estudios sobre este tema a nivel internacional. Por eso, no deja de producir sorpresa que cuando se realizan investigaciones o escritos o se organizan congresos relativos a la escolarización de alumnado de minorías étnicas en España a menudo se siga sin tener en cuenta a Ogbu y, por (...) el contrario, se repitan explicaciones manidas que Ogbu y sus seguidores ya hace tiempo se encargaron de rebatir con datos y argumentos muy sólidos. El presente documento tiene como único fin ser un material divulgativo sobre el modelo explicativo de John Ogbu. Este texto está realizado con fragmentos de artículos de Ogbu o bien de autores que han desarrollado este marco teórico y/o que lo han aplicado en España. La teoría explicativa ecológico-cultural fue elaborada por John Ogbu desde su primer estudio en 1974 hasta su fallecimiento en agosto del 2003, con diversas reformulaciones y nuevas aplicaciones empíricas de la misma, por parte del propio Ogbu y de otros investigadores.The explanatory model more contrast to understand the school situation of pupils from ethnic minorities is developed by the anthropologist John Ogbu and is also a central reference point in studies on this subject internationally. So do not stop producing surprise that when doing research or writing or organize conferences on the schooling of students from ethnic minorities in Spain are often still not taken into account and Ogbu, however, be repeated trite explanations Ogbu and his followers that long ago undertook to refute with facts and solid arguments. This document only serves to be an informative material on the explanatory model of John Ogbu. This text is made with fragments of Ogbu or articles of authors who have developed this framework and / or who have applied in Spain. The eco-cultural explanatory theory was developed by John Ogbu from his first studio in 1974 until his death in August 2003 with various reformulations and new empirical applications of the same, by Ogbu’s own and other researchers.

Considero un acierto el que se haya otorgado al escritor Amin Maalouf el premio Príncipe de Asturias de las Letras 2010. Merece la pena tomarse la molestia de leer con atención a este autor, pues ilumina como pocos los distintos ángulos concernientes a la convivencia y la diversidad.

In this paper, we use Saaty's Eigenvector Method and the Power Method as well as Ω=1, 2, ⋯, 9, 1/2, 1/3, ⋯, 1/9} and Ω-={1,2, ⋯,9,1, 1/2, ⋯,1/9} as the sets from which the pairwise comparison judgments are assigned at random to examine the variation in the values determined for the mean random consistency index. By extensive simulation analysis, we found that both methods produce the same values for the mean random consistency random index. Also, we found that the reason (...) for producing two different sets of values is the use of Ω vs. Ω- and not the selection of the Power Method vs. Saaty's Eigenvector Method. (shrink)

As it is known, there is no rule satisfying Additivity in the complete domain of bankruptcy problems. This paper proposes a notion of partial Additivity in this context, to be called µ-additivity. We find that µ-additivity, together with two quite compelling axioms, anonymity and continuity, identify the Minimal Overlap rule, introduced by Neill (1982).

In the industrial context, steel is a broadly-used raw material with applications in many different fields. Due to its high impact in the activity of many industries all over the world, forecasting its price is of utmost importance for a huge amount of companies. In this work, non-linear neural models are applied for the first time to different datasets in order to validate their suitability when predicting the price of this commodity. In particular, the NAR, NIO and NARX neural network (...) models are innovatively applied for the first time to forecast the price of hot rolled steel in Spain. Besides these variety of models, different datasets consisting of a set of heterogenous variables from the last seven years and related to the price of this commodity are benchmarked and analyzed. The results showed that NARX is the best performing model when the price of raw materials used to produce steel and the stock market prices of three major global steel producing companies are employed as input to this predictive model. Consequently, this result may boost the application of Machine Learning in companies, in order to schedule the supplying operations according to the price forecasting. (shrink)

The closeness of preferences in a preference profile has mainly been measured by aggregating the distances between each pair of preferences. We argue in this paper that some important information is lost in this process and we opt for considering the profile as a whole when constructing such a measure. With this idea in mind, we propose axioms a cohesiveness measure should satisfy and show that these properties fully characterize a new family of measures.

The aim of this article is to show the relationship between the Liber nouus de anima rationali, a work by Ramon Llull, and the psychological discourse in the thirtheenth century, by means of an analysis of its sources and the doctrinal and thematic context.

We revisit the concept of fairness in the Student Placement framework. We declare an allocation as α\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\upalpha $$\end{document}-equitable if no agent can propose an alternative allocation that nobody else might argue to be inequitable. It turns out that α\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\upalpha $$\end{document}-equity is compatible with efficiency. Our analysis fills a gap in the literature by giving normative support to the allocations improving, in terms of (...) efficiency, the Student Optimal Stable allocation. (shrink)

In the _Sententia cum questionibus in libros De anima I-II Aristotelis _, attributed to Petrus Hispanus, the recovered Aristotelian understanding of the soul does not completely replace the old Neoplatonic frame. Indeed, the commentary holds the existence of self-knowledge from the very beginning of the existence of the soul, before the acquisition of species. The aim of this paper is to describe _Sententia_’s view on self-knowledge analysing it in the context of its eclectic psychology and epistemology. I will attempt to (...) demonstrate that, although the commentary is set in an explicit Neoplatonic framework, Petrus Hispanus seems to be quite uncomfortable within this framework and becomes increasingly committed to the Aristotelian doctrine and its vision of science.

There is no corporal philosophy at the level of other philosophical subdisciplines. A research line has begun whose ultimate goal is to determine whether a somatic philosophy can be built. From a pragmatist and biopolitical approach, the present study investigated why it has not been possible to develop grounded somatic philosophy. As an answer, the “idealist–dualist episteme” is described, which encompasses invariants in the history of idealist philosophy at the ontological, gnoseological, ethical–political, and pedagogical levels. These constants reflect somatophobia, as (...) well as an ontological and gnoseological disregard of the body, which has led to the irrelevance of the body and corporeality in philosophy until the arrival of the “bodily turn”. The critique of this prevailing idealism and dualism will enable a review of current approaches based on these positions, such as embodiment, enactivism, embodied cognition, or embodied artificial intelligence. It opens up a new philosophical line with a universalis scope that is open to the eclectic construction of a pragmatic corporal philosophy that takes into account Chinese, Japanese, or African philosophies.

The author offers several keys to interpret the philosophy of G. Marcel and to internalize it in creative manner. Such keys are: “the different modes of reality”, and “the aesthetic experiences of declamation of a poem and interpretation of a musical work”. They enable us to clarify marcelian themes such as “the ontological demand”, “the union of participation”, “the relation of presence”, “the second reflection”….

Preventable childhood injuries and deaths are a major public health problem in the United States. In 2000, the most recent year for which mortality data are available, over 10,000 children from birth to age 18 died from unintentional injuries in the United States and nearly 3,000 from the same age group died from homicide or suicide. According to theChildhood Injury Fact Sheetproduced by the Centers for Disease Control and Prevention (CDC), “unintentional injuries are the leading cause of death for children (...) one to 21 years of age.”Preventing child fatalities requires further understanding of the causes and circumstances surrounding child deaths. One mechanism for doing this is multidisciplinary child fatality review teams. These teams exist at the state and local level and perform the functions of identifying, reviewing, and recommending preventive measures to reduce the number of preventable child deaths and life-threatening injuries.
