About the problems caused by the Gini and Kakwani index of inequality measurement
1997
On fait le point sur les faiblesses des indices de Gini et de Kakwani lorsque la dominance entre distributions n’est pas garantie : à un même Gini peuvent correspondre plusieurs distributions différentes et à une même valeur du Kakwani peuvent correspondre une infinité de couples d’ indices de Gini. On propose alors d ’approximer la courbe de Lorenz typiquement en deux ou trois parties linéaires, puis de décrire la position de son coude ou de ses deux coudes par deux ou quatre nombres qui suffisent caractériser complètement sa forme et la catégorie à laquelle elle appartient. Une procédure de choix entre distributions est proposée, basée sur une application du maximin : entre deux distribut…
A Study on the Assessment of Introductory Computational Thinking via Scratch Programming in Primary Schools
2018
Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to i…
Peri-Implant Behavior of Tissue Level Dental Implants with a Convergent Neck
2021
Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck
Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method
2008
Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…
Factores de riesgo de la fibrilación auricular tras la cirugía torácica
2023
La fibrilación auricular tras la cirugía torácica (FAPO) se ha identificado como la complicación cardíaca más frecuente tras la cirugía torácica no cardíaca, resaltándose el amplio rango de incidencia, entre el 1.2% y el 25.8%. Ello se ha atribuido a factores como: (a) ausencia de una definición uniforme de FAPO, (b) distintos procedimientos quirúrgicos englobados en la misma serie, (c) inclusión de pacientes con diferente indicación quirúrgica, (d) variabilidad en la monitorización postoperatoria, (e) inclusión de pacientes con el antecedente personal de fibrilación auricular, y (f) observancia de otras arritmias cardíacas. Además, a pesar de la identificación de factores predictivos y de …
On elliptic equations involving the 1-Laplacian operator
2018
El objetivo de esta tesis doctoral es dar a conocer los resultados obtenidos sobre existencia, unicidad y regularidad de las soluciones de diferentes ecuaciones elípticas regidas por el operador 1-laplaciano. El primer capítulo está dedicado al estudio de la ecuación - div (Du/|Du|) + g(u) |Du| = f(x) en un subconjunto abierto y acotado U de R^N con frontera Lipschitz, con la condición de Dirichlet u=0 en la frontera, tomando una función f positiva y siendo g una función real, continua y positiva. Por un lado, obtenemos soluciones no acotadas cuando el dato f pertenece al espacio de Marcinkiewicz L^{N,\infty}(U), por lo que debemos introducir la definición apropiada para este tipo de soluci…

Tourism association development tendencies in Latvia
2019
Tourism as one of the leading industries has gained attention from scholars that are researching different influencing factors of tourism destination development. One of the challenges that tourism destinations need to overcome is heterogeneous nature of tourism industry that could be solved with the help of professional and regional tourism associations. Current tourism technology from one side creates additional potential for tourism enterprises and destinations, from other side it could decrease need for traditional tourism associations. The Investment and Development Agency of Latvia (LIAA) indicates eighteen active tourism associations in Latvia. These tourism associations have been go…
"Łemko ból nosi w genach". Oblicze łemkowskiej postpamięci
2021
The material being presented in this paper is a study case – the analysis of an interview which the author conducted with a granddaughter of the Lemkos dis-placed to Lower Silesia in 1947 as part of Operation Vistula. The narration of the interlocutor overfilled with emotions reveals the traumatic context of her in-cessant search for an answer to the question: Who am I? Since she did not agree to make the entirety of her talk public, transferring in this way the obligation to protect her name onto the author, the interview became a unique personal ex-perience for the latter at the same time. Therefore, only those fragments of the above-mentioned interview are referred to in the text, which …
Restituir el poder, desarrollar la autonomia: trabajo social, responsabilidad local y participación comunitaria en un proyecto de promoción humana en…
2016
El desarrollo es un proceso desequilibrado, en el que operan tensiones, estímulos, contradicciones sectoriales y factores endógenos, peculiares de una única realidad, los cuales requieren en cada proyecto de cooperación un significativo compromiso de conocimiento y de comprensión del rol que juegan los factores de incertidumbre, los vínculos y los factores colaterales de cada elemento significativo (social, cultural, económico, político, etc.). Lo anterior requiere, en primer lugar prever la constante lectura, sin prejuicios, de las necesidades y de las prioridades de los beneficiarios mediante enfoques participativos, junto a una evaluación de los proyectos de desarrollo que no se encomien…
