Connectedness and connectivity of the Natura 2000 network of protected areas across country borders in the European Union
2012
Abstract We studied the spatial connectedness of Natura 2000 site boundaries and the functional connectivity of the Natura 2000 network across the 34 terrestrial borders of the European Union. Connectivity was measured by the dispersal success of 192 reptile, amphibian, invertebrate and plant species from Annex II of the European Union Habitats Directive, based on the presence of same species on both sides of the borders. Connectedness and connectivity varied greatly between state borders, with good and bad examples found in all parts of the European Union. Connectedness and connectivity were positively correlated. However, a few outlying examples showed that good connectedness is not neces…
For Whom is MAI? A Theoretical Perspective on Multilateral Agreements on Investments
2001
Why do we observe some LDCs objecting the prospect of a Multilateral Agreement on Investment (MAI), although they have been keen to liberalize investment in preferential agreements in recent years? In this paper, we analyse the issue of MAI implementation and assess the welfare consequences of such kind of agreements. In our model, participation to MAI involves a trade-off between less rent extraction from multinational firms (MNEs) and more abundant FDI inflows. At equilibrium, either all countries enter MAI, or all countries stay out, or only some of them enter. Coordination problems may induce multiple equilibria: the three typesof equilibria may coexist. So, the implementation of MAI ma…
Sport and Quality of Life
2022
Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…
Modular Breath Analyzer (MBA): Introduction of a Breath Analyzer Platform Based on an Innovative and Unique, Modular eNose Concept for Breath Diagnos…
2021
Exhaled breath analysis for early disease detection may provide a convenient method for painless and non-invasive diagnosis. In this work, a novel, compact and easy-to-use breath analyzer platform with a modular sensing chamber and direct breath sampling unit is presented. The developed analyzer system comprises a compact, low volume, temperature-controlled sensing chamber in three modules that can host any type of resistive gas sensor arrays. Furthermore, in this study three modular breath analyzers are explicitly tested for reproducibility in a real-life breath analysis experiment with several calibration transfer (CT) techniques using transfer samples from the experiment. The experiment …
Responsabilidad de los administradores de hecho por el déficit concursal. Estudio comparado del Derecho español, uruguayo y argentino
2014
La hipótesis de este trabajo y su hilo conductor consiste en que la extensión de la responsabilidad por el déficit concursal al administrador de hecho es una decisión acertada de los legisladores españoles y uruguayos, pues obliga a la cobertura del descubierto patrimonial a aquella persona que realmente tomó las decisiones que generaron o agravaron la insolvencia. Bajo ésta subyace otra hipótesis: que la Ley concursal española y la uruguaya reflejan un cambio de modelo en materia de responsabilidad concursal, que adecua la legislación concursal al desarrollo que en general ha tenido lugar en la legislación de sociedades, de mercado de valores, de defensa de la competencia y medioambiental.…
El cambio estratégico y sus dimensiones: implicaciones sobre la composición y estructura de los equipos directivos
2017
El objetivo de esta tesis doctoral es analizar las implicaciones del cambio estratégico sobre el equipo directivo. Este estudio extiende la investigación sobre equipos directivos (TMT) basada en la Upper Echelons Theory planteando un modelo recursivo y dinámico de la relación características del TMT y cambio estratégico. En concreto analizaremos como las distintas dimensiones del cambio estratégico –alcance, intensidad y dirección– afectan a la composición y estructura del TMT, y específicamente, sus implicaciones sobre el tamaño, heterogeneidad (antigüedad, background educativo y funcional), rotación y estructura de poder en el TMT (concentración contra dispersión).
Desarrollo Directivo en la toma de decisiones estratégicas y cambio estratégico: el Capital Psicológico como variable facilitadora
2019
Con esta Tesis doctoral pretendemos contribuir al desarrollo directivo desde la toma de decisiones estratégicas y el cambio estratégico en las organizaciones, profundizando en como el capital psicológico del equipo directivo y su desarrollo se convierten en una variable facilitadora de este proceso crítico hoy en las empresas y en sus equipos directivos. En entornos hostiles como los actuales, las resistencias al cambio e inercias en la organización y en las decisiones, hacen de la renovación estratégica un proceso realmente complejo. A lo largo de la investigación de la presente Tesis estamos analizando cómo afecta el Capital Psicológico de los directivos de las empresas a sus procesos dec…
The Process of CEO Dismissal: An Exploratory study
2018
The decision to change the CEO is one of the most important decisions of the Board of Directors in a company. This study increases understanding of the process that leads to a Board’s decision to dismiss the CEO under conditions of poor performance, and of the meaning of attributions in CEO dismissal. The role of the Chair of the Board in this process is also explored. An exploratory, empirical study concerning nine CEO dismissal processes is conducted based on open-ended interviews with seven Chairpersons of the Board. The findings shed light on the issues that impact the relationship between poor company performance and CEO dismissal. In particular, the results increase understanding of t…
Solvent Determines Nature of Effective Interactions between Nanoparticles in Polymer Brushes
2015
We study the effective interaction between two parallel rod-like nanoparticles in swollen and collapsed polymer brushes as a function of penetration depth by 2D self-consistent field calculations. In vertical direction, the interaction is always attractive. In lateral direction, the behavior under good and poor solvent conditions is qualitatively different. In swollen brushes (good solvent), nanoparticles always repel each other. In collapsed brushes (poor solvent), we identify two different regimes: an immersed regime, where the nanoparticles are fully surrounded by the brush, and an interfacial regime, where they are located in the interface between brush and solvent. In the immersed regi…

2020
Objectives:\ud \ud The aim of this umbrella review was to determine the effect of physical activity/exercise on improving cognitive and noncognitive outcomes in people with MCI (mild cognitive impairment) and dementia.\ud \ud Design:\ud \ud Umbrella review of systematic reviews (SR), with or without meta-analyses (MAs), of randomized controlled trials (RCTs) and observational studies.\ud \ud Settings and Participants:\ud \ud People with MCI or dementia, confirmed through validated assessment measures.
