Minería de oro: promesas, conflictos y desilusión en Cerro de San Pedro, México

2018

Este artículo analiza los conflictos por los recursos agua y tierra en Cerro de San Pedro, México, cuando una empresa minera canadiense inició una mina a cielo abierto en este municipio. Examinamos diferentes posiciones en el conflicto entre la mina de oro y los habitantes locales, y cómo ambivalentes regulaciones nacionales y organismos gubernamentales permitieron que una empresa extranjera operara sin los permisos requeridos. Para analizar el conflicto utilizamos el marco de Escalones de Análisis de Derechos, que distingue cuatro capas de disputa: sobre los recursos; el contenido de las normas; el poder de decisión; y los discursos. Discutimos cómo la auto-representación de la empresa ext…

Nowhere Home: The Waiting of Vulnerable Child Refugees

2020

In her 2012 documentary Nowhere Home, filmmaker Margreth Olin sheds light on the vulnerabilities and injurabilities of child migrants subjected to prolonged waiting. The documentary shows unaccompanied minors being offered only temporary residence and thus identifies why these irregular migrants can be characterized as ‘particularly vulnerable’ by having their childhoods put on hold. Although the concept is contested, I conceive vulnerability as based on humans’ existential precondition in terms of something bodily and enabling. Due to child refugees’ particular vulnerability, prolonged waiting can violate their inherent dignity, bodily health, life quality and human rights. Therefore, in l…

Multialternating graded polynomials and growth of polynomial identities

2012

Let G be a finite group and A a finite dimensional G-graded algebra over a field of characteristic zero. When A is simple as a G-graded algebra, by mean of Regev central polynomials we construct multialternating graded polynomials of arbitrarily large degree non vanishing on A. As a consequence we compute the exponential rate of growth of the sequence of graded codimensions of an arbitrary G-graded algebra satisfying an ordinary polynomial identity. In particular we show it is an integer. The result was proviously known in case G is abelian.

Don Juan de Austria

La voce, costruita su fonti archivistiche e bibliografiche, delinea la biografia di don Juan de Austria, mettendo in relazione dinamiche private con il più ampio contesto politico della monarchia spagnola nella seconda metà del XVI secolo The voice, built on archival and bibliographic sources, outlines the biography of don Juan de Austria, linking private dynamics with the broader political context of the Spanish monarchy in the second half of the sixteenth century

Eiropas Cilvēktiesību un pamatbrīvību aizsardzības konvencijas 16. protokols: mērķi, saturs, nozīme

2016

Eiropas Cilvēktiesību un pamatbrīvību aizsardzības konvencijas (turpmāk - Konvencija) 16.protokols ir daļa no pasākumiem, kas tiek veikti Konvencijas ilgtermiņa reformu kontekstā. Ar to paplašina Eiropas Cilvēktiesību tiesas (turpmāk – ECT) rekomendējošo jurisdikciju un ievieš jaunu mehānismu Konvencijas cilvēktiesību aizsardzības sistēmā, atbilstoši kuram šī protokola dalībvalstu pēdējo instanču tiesas un tribunāli varēs lūgt ECT sniegt rekomendējošu viedokli. Darbā autors atklāj Konvencijas 16.protokola mērķus, analizē un pēta protokola saturu. Tiek secināts, ka regulējums kaut gan nepilnīgs, ir apmierinošs. Darbā arī tiek izvērtēta protoko…

Testing alternative vicariance scenarios in Western Mediterranean discoglossid frogs

2004

Dated molecular phylogenies are often used to interpret evolutionary history with respect to paleogeographic events. Where more than one interpretation is possible, it is desirable but difficult to assess the alternatives in an objective manner. The present work demonstrates a formalized method for testing molecular clock calibrations and biogeographic scenarios based on them. We assessed the plausibility of several previously published biogeographic hypotheses, using the frog genera Alytes, Discoglossus, and Bombina as model groups. Our data set comprised ca. 900bp of partial mitochondrial 16S and 12S rRNA gene sequences (both genes evolved in a clock-like manner across genera) from nearly…

A problem-adjusted genetic algorithm for flexibility design

2013

Many present markets for goods and services have highly volatile demand due to short life cycles and strong competition in saturated environments. Determination of capacity levels is difficult because capacities often need to be set long before demand realizes. In order to avoid capacity-demand mismatches, operations managers employ mix-flexible resources which allow them to shift excess demands to unused capacities. The Flexibility Design Problem (FDP) models the decision on the optimal configuration of a flexible (manufacturing) network. FDP is a difficult stochastic optimization problem, for which traditional exact approaches are not able to solve but the smallest instances in reasonable…

Sampling properties of the Bayesian posterior mean with an application to WALS estimation

2022

Many statistical and econometric learning methods rely on Bayesian ideas, often applied or reinterpreted in a frequentist setting. Two leading examples are shrinkage estimators and model averaging estimators, such as weighted-average least squares (WALS). In many instances, the accuracy of these learning methods in repeated samples is assessed using the variance of the posterior distribution of the parameters of interest given the data. This may be permissible when the sample size is large because, under the conditions of the Bernstein--von Mises theorem, the posterior variance agrees asymptotically with the frequentist variance. In finite samples, however, things are less clear. In this pa…

Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes

2022

Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
