Semigenerated Carnot algebras and applications to sub-Riemannian perimeter
2021
This paper contributes to the study of sets of finite intrinsic perimeter in Carnot groups. Our intent is to characterize in which groups the only sets with constant intrinsic normal are the vertical half-spaces. Our viewpoint is algebraic: such a phenomenon happens if and only if the semigroup generated by each horizontal half-space is a vertical half-space. We call semigenerated those Carnot groups with this property. For Carnot groups of nilpotency step 3 we provide a complete characterization of semigeneration in terms of whether such groups do not have any Engel-type quotients. Engel-type groups, which are introduced here, are the minimal (in terms of quotients) counterexamples. In add…
Procesos léxicos y de comprensión lectora en alumnos de educación secundaria
2016
La comprensión lectora es un proceso complejo que requiere tanto la “construcción” como la “integración” de la información, siendo por tanto un proceso interactivo en el que intervienen una gran cantidad de procesos mentales. Este hecho conlleva que exista una gran heterogeneidad de dificultades en la comprensión. El objetivo del presente estudio consiste en analizar las posibles diferencias en cuanto al acceso al léxico y los procesos de comprensión entre un grupo de alumnos con dificultades en la comprensión (DCL) y otro grupo de alumnos sin DCL. Participaron 84 adolescentes (42 con DCL y 42 sin DCL) de 12 a 16 años escolarizados en la etapa de Educación Secundaria Obligatoria. Los result…

"Learning Online" for Vocational Teachers : Visualisation of a Competence-Based Approach in Digital Open Badge-Driven Learning
2018
Vocational education in Finland is based on competence-based qualification requirements. Meanwhile, digital open badges promote competence-based assessment and shared expertise in digital environments. The educational setting supports gamified learning solutions and enhances student motivation. The current study aims to examine how learners experience the competence-based approach in the badge-driven learning process of professional development. The theoretical framework focuses on the concept of instructional badging in the competence-based approach. Coordinated by the country’s northernmost school of profesional teacher education, “Learning Online” is a national professional development p…
Structure of equilibrium states on self-affine sets and strict monotonicity of affinity dimension
2016
A fundamental problem in the dimension theory of self‐affine sets is the construction of high‐dimensional measures which yield sharp lower bounds for the Hausdorff dimension of the set. A natural strategy for the construction of such high‐dimensional measures is to investigate measures of maximal Lyapunov dimension; these measures can be alternatively interpreted as equilibrium states of the singular value function introduced by Falconer. While the existence of these equilibrium states has been well known for some years their structure has remained elusive, particularly in dimensions higher than two. In this article we give a complete description of the equilibrium states of the singular va…
Effective charge from lattice QCD
2020
Using lattice configurations for quantum chromodynamics (QCD) generated with three domain-wall fermions at a physical pion mass, we obtain a parameter-free prediction of QCD's renormalisation-group-invariant process-independent effective charge, $\hat\alpha(k^2)$. Owing to the dynamical breaking of scale invariance, evident in the emergence of a gluon mass-scale, this coupling saturates at infrared momenta: $\hat\alpha(0)/\pi=0.97(4)$. Amongst other things: $\hat\alpha(k^2)$ is almost identical to the process-dependent (PD) effective charge defined via the Bjorken sum rule; and also that PD charge which, employed in the one-loop evolution equations, delivers agreement between pion parton di…
EL derecho a la resistencia como garantía de los derechos en el sistema constitucional ecuatoriano
2017
RESUMEN: El presente articulo analiza el tratamiento juridico que el derecho a la resistencia recibe en Ecuador, viendo que formula plantea la Constitucion ecuatoriana de 2008 para compatibilizar resistencia y Derecho en el interior del ordenamiento juridico. Sin embargo, veremos tambien cuales son aquellos factores politicos y jurisprudenciales que han imposibilitado en la practica esta armonizacion y plantearemos algunas propuestas para desencallar tal situacion. ABSTRACT: This article will discuss the right to resistance and the legal treatment it is given in Ecuador. The analysis includes the formula that the Ecuadorian Constitution of 2008 proposes to reconcile resistance and Law withi…
La dirigenza pubblica: criteri di identificazione e specialità della disciplina.
Nel tentativo di far luce sui maggiori coni d’ombra che emergono dalla relativa disciplina speciale del rapporto di lavoro, la tesi riflette l’esigenza di un ripensamento sistematico della figura del dirigente pubblico, nell’ottica di prospettare de iure condendo possibili correttivi. A tal fine, sono analizzate le peculiarità ed attribuzioni della dirigenza pubblica, in chiave storico-evolutiva, alla luce dei principi costituzionali e del processo riformatore che ha contrassegnato la magmatica materia, a tutt’oggi in atto. E’, altresì, rivolto uno sguardo comparativistico alla disciplina del personal directivo español, rivelandosi la stessa, speculare a quella del dirigente italiano quanto…
Il futuro del costituzionalismo (se il costituzionalismo ha un futuro)
2022
Il costituzionalismo è in crisi? Se con questa ci riferiamo soltanto a un discorso giuridico improntato al linguaggio dei diritti e a un certo assetto tra poteri che valorizza il potere giudiziario a discapito del legislativo e dell’esecutivo, allora non si può che rispondere negativamente. Se invece consideriamo parte integrante del costituzionalismo l’individualismo di matrice illuminista e la convinzione che esista uno zoccolo duro di valori morali universalmente condivisi sui quali edificare un futuro di pace e prosperità dell’umanità, allora è difficile negare la crisi del costituzionalismo. Is constitutionalism in crisis? If by ‘constitutionalism’ we only refer to a legal discourse gr…
