Agricultural landscapes and biodiversity conservation: a case study in Sicily (Italy)

2015

The diversity of life is made up not only of the diversity of plants and animal species, habitats and ecosystems, but also of the diversity of human cultures. These diversities interact with one another in complex ways and express the mutual adaptation between humans and the environment at local level. Sicilian traditional agro-ecosystems, due to the history of the territory and the resulting social and economic context, are configured in a heterogeneous mosaic rich in residual features of environmental value, which enhance the connectivity of the ecological network and support a high proportion of species that are rare or of conservation concern. As a case study we analyzed the characteris…

Emotions in Economic Decision Making: A Multidisciplinary Approach

2013

AbstractAccording to classical and neoclassical economics, decisions are made based on information and cost-benefit analysis. In reality, the decision making process is much more complex than previously thought, because it also involves psychological factors. Decision making is interdisciplinary, researched by psychologists, sociologists, economists, philosophers, neuroscientists and others. These fields have distinctive and common concepts about decision making. The aim of this paper is to identify what role emotions play in the economic decision making process. The paper focuses on describing and explaining the interconnection of sciences, such as economics, psychology and neuroscience, b…

Asset price dynamics in a “bull and bear market”

2021

Abstract We generalize an existing asset market model with heterogenous agents. In particular, we consider the case in which no-trade and low-trade intervals of chartists and fundamentalists respectively are not congruent. Thus we model chartist and fundamentalists who respond to asset prices in agent-specific neighborhoods around the fundamental value with different trade intensities. The resulting asset price dynamics is generated by a one-dimensional 5-piece linear map with discontinuities. Our analysis of this map focusses on coexisting price equilibria. Conditions for their existence and stability are determined analytically. By visualizing the results we allow for a basic bifurcation …

Cámaras de comercio: una nueva gestión. El enfoque del Cuadro de Mando Integral en las Cámaras Españolas

2020

Las Cámaras de Comercio, una de las organizaciones empresariales multisectoriales más extendidas en el mundo, se caracterizan por tres condiciones que las diferencian de otras agrupaciones empresariales: no tienen fines de lucro, comprenden diversos sectores dentro de un territorio específico, y son autogestionadas. En el presente trabajo, después de tratar sobre qué tipo de entidad es una Cámara, la evolución en su organización, y la utilidad de su labor para la sociedad y la economía españolas, ponemos de manifiesto la oportunidad de que éstas modifiquen su gestión introduciendo el sistema, ya bien conocido y aplicado en el sector privado, del Cuadro de Mando Integral (CMI), como instrume…

Opportunity Recognition in Social Entrepreneurship

2012

Opportunity recognition (OR) is at the very heart of entrepreneurship. However, research on OR in the context of social entrepreneurship is still in its early stages. First, this article identifies, codifies and analyses OR-relevant articles on social entrepreneurship (SE) through the lens of Sarasvathy’s three views of entrepreneurial opportunity recognition. In the second step, statistical methods are applied on the results to indicate possible correlations among different schools of thought in SE and views on OR. OR in social ventures is found to be a prevalent topic in SE literature and differences in OR between social and commercial ventures are found.

Modeling the influence of alternative forest management scenarios on wood production in the mediterranenan region. The MiMoSe approach.

2014

Ecosystem services (ES) are defined as the benefits that human obtain from ecosystems. Forest ecosystems provide many essential goods and services, such as flood and landslide control, erosion prevention and maintenance of soil fertility, water and air quality, biodiversity, wildlife habitat, recreational space for humans and aesthetic appreciation of natural landscapes, wood for fuel, construction and fibre, biomass for energy, and non-timber forest products. The quality and quantity of these goods and services are influenced by forest management, especially in the Mediterranean area where the forest has been exploited for a long time. In this study, we propose a method (MiMoSe- Multiscale…

Atrial Fibrosis Hampers Non-invasive Localization of Atrial Ectopic Foci From Multi-Electrode Signals: A 3D Simulation Study

2018

[EN] Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be located virtually in any atrial region. Multi-electrode surface ECG systems allow acquiring dense body surface potential maps (BSPM) for non-invasive therapy planning of cardiac arrhythmia. However, the activation of the atria could be affected by fibrosis and therefore biomarkers based on BSPM need to take these effects into account. We aim to analyze the effect of fibrosis on a BSPM derived index, and its potential application to predict the location of ectopic foci in the …

Characterization of murine monoclonal antibodies against the Ro52 autoantigen

1997

SUMMARY Immunization of BALB/c mice with purified recombinant human Ro52 protein resulted in three anti-Ro52 MoAbs termed 2E7, 4C6 and 4F11. All anti-Ro52 MoAbs specifically reacted with recombinant human Ro52 protein, and also with Ro52 protein in total extracts of all human cell lines analysed, including the epithelial cell line HeLa, the B cell line Raji, the bladder carcinoma cell line RT112, and a fibroblast cell line derived from patients with xeroderma pigmentosum. The anti-Ro52 MoAbs were able to immunoprecipitate the recombinant human Ro52 protein expressed in wheat germ extract, but failed to precipitate hY RNAs from cell extracts. The staining pattern of the MoAbs strongly differ…

Assisting Electrophysiological Substrate Quantification in Atrial Fibrillation Ablation

2019

[EN] Catheter ablation (CA) is the most popular treatment of atrial fibrillation (AF) with good results in paroxysmal AF, while its efficiency is significantly reduced in persistent AF. With the equipment used for CA strongly depending on electro-gram (EGM) fractionation quantification, the use of a reliable fractionation estimator is crucial to reduce the high recurrence rates in persistent AF. This work introduces a non-linear EGM fractionation quantification technique, which is based on coarse-grained correlation dimension (CGCD) computed over epochs of 1 second. Recordings were firstly normalized, denoised and lowpass filtered. The final CGCD value was calculated by the median CGCD valu…
