The role of language on the reversal error. A study with bilingual Basque-Spanish students
2019
The reversal error is a prevalent phenomenon that consists of reversing the relationship between two variables when writing equations from comparison in verbal language. A study with 169 Basque/Spa...
Qualitative remarks on some non-linear aspects of the radio-pulsar magnetosphere
2011
In the class of the submodels SCLF (space-charge limited flow) of the family of "gap-plus-PPF" models, let us exposes some qualitative remarks on the possible turbulent dynamics showed by the zone (II) (see Fig. 1 of the text) of the acceleration zone of the "direct inner gap". Furthermore, we will discuss some consequent physical implications (as, for instance, self-focussing phenomena, Petviashvili's diamagnetism, and so on) concerning structure and physical phenomenology of the remaining subzones (above the subzone (II)) of the given acceleration zone, in connection with possible models for the external solid crust of the radio-pulsar.
An ecological dynamics rationale to explain home advantage in professional football
2016
Despite clear findings, research on home advantage in team sports lacks a comprehensive theoretical rationale for understanding why this phenomenon is so compelling. The aim of this study was to provide an explanatory theoretical rationale in ecological dynamics for the influence of home advantage observed in research on professional football. We recorded 30 competitive matches and analyzed 13958 passes, from one highly successful team in the Portuguese Premier League, during season 2010/2011. Performance data were analyzed using the Match Analysis Software—Amisco[Formula: see text] (version 3.3.7.25), allowing us to characterize team activity profiles. Results were interpreted from an ecol…
Adaptive interpolation with maximum order close to discontinuities
2022
Abstract Adaptive rational interpolation has been designed in the context of image processing as a new nonlinear technique that avoids the Gibbs phenomenon when we approximate a discontinuous function. In this work, we present a generalization to this method giving explicit expressions for all the weights for any order of the algorithm. It has a similar behavior to weighted essentially non oscillatory (WENO) technique but the design of the weights in this case is more simple. Also, we propose a new way to construct them obtaining the maximum order near the discontinuities. Some experiments are performed to demonstrate our results and to compare them with standard methods.
A universal definition of life: autonomy and open-ended evolution.
2004
Life is a complex phenomenon that not only requires individual self-producing and self- sustaining systems but also a historical-collective organization of those individual systems, which brings about characteristic evolutionary dynamics. On these lines, we propose to define univer- sally living beings as autonomous systems with open-ended evolution capacities, and we claim that all such systems must have a semi-permeable active boundary (membrane), an energy trans- duction apparatus (set of energy currencies) and, at least, two types of functionally interdependent macromolecular components (catalysts and records). The latter is required to articulate a 'phenotype- genotype' decoupling that…
Theoretical Approach: The Situation-Structural Model as an Analytical Tool to Explain Regionalism
2017
This chapter provides the analytical framework and guiding theory for this work. Muntschick develops an innovative situation-structural model to the analysis of regionalism that goes beyond Euro-centric and classic integration theories because it takes the impact of external actors explicitly into account. This—often neglected—aspect is of crucial importance in regions with mainly developing countries that show strong and asymmetric relations to extra-regional actors. Besides offering clear-cut definitions of regions and regionalism, Muntschick draws on insights from cooperation and regime theory in order to specify assumptions and deduce hypotheses about the emergence, institutional design…
Film Tourism – Locations Are the New Stars
2009
There once was a time when the actual attraction of a movie lied in the capability of the celluloid to let the spectators escape from the everyday, a spare time to leave the life-world environment behind and live the life of a thrilling armchair traveller. Foreign countries and remote regions could easily be mapped and visited without travelling to the actual location. Considering that “the modern world is very much a ‘seen’ phenomenon“ (Jenks 1995:2), one has to come to the assumption that present day travelling and watching movies are somehow connected. Tourism originally was perceived as visitors travelling, whether within their own country or internationally, for pleasure and relaxation…
Introduction to Part V
2018
The shock of defeat at the end of the First World War left many German academics dumbfounded and numb. Even Hilbert, an outspoken internationalist, was deeply disillusioned by the chaos and instability that plagued the early Weimar years. Already during the war, political differences widened the gulf that had already formed within the Gottingen Philosophical Faculty, whose conservative members felt they were constantly being provoked by the “Hilbert faction.” The controversy over Emmy Noether’s candidacy to habilitate in 1915, mentioned in the introduction to Part IV, was only one of many such instances. Others were even more serious, as when Hilbert and his pacifist friends were accused of…
Community garden initiatives addressing health and well‐being outcomes: A systematic review of infodemiology aspects, outcomes, and target populations
2021
Previous research has suggested that activities such as community gardens could offer a wide range of health benefits. The aim of the article is to systematically review the available literature to analyse the magnitude of the phenomenon, the geographical distribution, and the main characteristics in terms of health outcomes and target populations. The search addresses the question whether the activity in community gardens improves health and well-being outcomes of individuals. From the total amount of 7226, 84 selected articles showed that:(1) up to 50% are published by U.S. universities or institutions; (2) up to 44% of the studies considered “community gardens” as the main activity of th…
Ética de la asistencia primaria a los niños de procedencia internacional
2012
La inmigración se ha convertido en un fenómeno universal. Uno de sus efectos es el incremento de los niños de procedencia internacional en las consultas de pediatría. Se trata de una población doblemente vulnerable, por tratarse de niños y por proceder de contextos culturales extraños a los del país de acogida. Ante esta realidad emergente es imprescindible preguntarse por el tipo de asistencia sanitaria que deben recibir. En el presente artículo se proponen principios éticos de actuación inspirados en las principales normas internacionales sobre bioética y derechos de los niños: principio de vulnerabilidad; principio de respeto y amor, y principio de acceso y atención sanitaria. Finalmente…
