Test module filtrations for unit $F$-modules
2015
We extend the notion of test module filtration introduced by Blickle for Cartier modules. We then show that this naturally defines a filtration on unit $F$-modules and prove that this filtration coincides with the notion of $V$-filtration introduced by Stadnik in the cases where he proved existence of his filtration. We also show that these filtrations do not coincide in general. Moreover, we show that for a smooth morphism $f: X \to Y$ test modules are preserved under $f^!$. We also give examples to show that this is not the case if $f$ is finite flat and tamely ramified along a smooth divisor.
Bi-Sobolev extensions
2022
We give a full characterization of circle homeomorphisms which admit a homeomorphic extension to the unit disk with finite bi-Sobolev norm. As a special case, a bi-conformal variant of the famous Beurling-Ahlfors extension theorem is obtained. Furthermore we show that the existing extension techniques such as applying either the harmonic or the Beurling-Ahlfors operator work poorly in the degenerated setting. This also gives an affirmative answer to a question of Karafyllia and Ntalampekos.
Gradient Estimate for Solutions to Poisson Equations in Metric Measure Spaces
2011
Let $(X,d)$ be a complete, pathwise connected metric measure space with locally Ahlfors $Q$-regular measure $\mu$, where $Q>1$. Suppose that $(X,d,\mu)$ supports a (local) $(1,2)$-Poincar\'e inequality and a suitable curvature lower bound. For the Poisson equation $\Delta u=f$ on $(X,d,\mu)$, Moser-Trudinger and Sobolev inequalities are established for the gradient of $u$. The local H\"older continuity with optimal exponent of solutions is obtained.
Comment évaluer et mesurer la conflictualité liée aux usages de l'espace ? Eléments de méthode et de repérage
2010
Cet article a pour objet de présenter le travail réalisé depuis quelques années par une équipe pluridisciplinaire sur la question des conflits d’usage de l’espace et de révéler la méthodologie d’enquête et de collecte de données, ainsi que la structure de la base de données qui en est issue. Dans un premier temps nous procédons à une définition du champ des investigations, en donnant une définition de ces conflits, de leurs caractéristiques, des mobiles et des manifestations de la conflictualité, ainsi que des acteurs impliqués (I). Nous exposons ensuite notre méthode de repérage des conflits, fondée sur un diagnostic de zone et la mise en commun de différentes méthodes de recueil de donnée…
La prestación de maternidad en los supuestos de gestación subrogada
2018
Surrogate pregnancy, as a technique of assisted reproduction prohibited by Spanish law, raises a number of legal questions than, in certain cases, trascend of the Civil Law. Specifically, it has been discussed about de possibility that de person or persons consigner in the gestation contract substitution have access to the provision for maternity benefit. Recently, the Spanish Supreme Court has responded to this issue in the sense of recognizing the right to the provision for maternity benefit to the father or mother ?in fact?, efecttively, develop own parental powers.
Citizen science for scientific literacy and the attainment of sustainable development goals in normal education
2020
Curricular integration of the formal teaching of citizen science can bring to the classroom aspects of scientific literacy that encourage the involvement of citizens. In particular, these include non-epistemic aspects related to the sociology of science (which are often not transferred to the classroom). Furthermore, this practice raises awareness among students, and encourages them to become participants in the attainment of the United Nations&rsquo
Two-year retrospective analysis of the international impact of Journal of Optometry: part II
2011
The Journal of Optometry – Peer-reviewed Journal of the Spanish General Council of Optometrists- was launched in March 2008 publishing the first issue by September 2008. It is now reaching 2.5 years of activity in spreading clinical and scientific knowledge in the field of Optometry and Visual Science and related areas. Despite this short path within the international scientific publication scenario, it is appropriate to stop and reflect about the challenges, achievements and the numbers that are making J Optom a reference in this competitive area. In this editorial we will discuss the steps followed to setup the journal and the actual international impact in terms of audience from the read…
Exploring the contribution of grassroots innovations to justice: using the capability approach to normatively address bottom-up sustainable transitio…
2020
There is growing interest in the potential of grassroots innovations for the transition towards more just and sustainable societies. Nevertheless, there is lack of clear normative discussion regarding these processes. The paper strives to propose and test a framework that enables an analysis of how and in which sense specific grassroots innovation processes may be contributing to the construction of more just societies. To this end, we connect elements of the multi-level perspective on sociotechnical transitions (frequently used in the analysis of grassroots innovations) with elements of the capability approach, which offers a multi-dimensional perspective to justice. The framework is used …
Cover Crop Impact on Soil Organic Carbon, Nitrogen Dynamics and Microbial Diversity in a Mediterranean Semiarid Vineyard
2020
Cover crop (CC) management in vineyards increases sustainability by improving soil chemical and biological fertility, but knowledge on its effects in semiarid soils is lacking. This study evaluated the effect of leguminous CC management on soil organic carbon (SOC) sequestration, soil nitrate content and microbial diversity in a semiarid vineyard, in comparison to conventional tillage (CT). SOC and nitrate were monitored during vine-growing season
