Financial institutions’ risk profile and contribution to the sustainable development goals

2021

This study analyses the impact of Spanish financial institutions’ risk profile on their contribution to the 2030 Agenda. Financial institutions play a significant role in ensuring financial inclusion and sustainable economic growth and usually incorporate environmental and social considerations into their risk management systems. The results show that financial institutions with less capital risk, with lower management efficiency and with higher market risk usually make higher contributions to the Sustainable Development Goals (SDGs), according to their sustainability reports. The novel aspect of the present study is that it identifies the risk profile of financial institutions that incorpo…

Characterization of a fractured basement reservoir using high-resolution 3D seismic and logging datasets: A case study of the Sab'atayn Basin, Yemen.

2018

The Sab'atayn Basin is one of the most prolific Mesozoic hydrocarbon basins located in central Yemen. It has many oil producing fields including the Habban Field with oil occurrences in fractured basement rocks. A comprehensive seismic analysis of fractured basement reservoirs was performed to identify the structural pattern and mechanism of hydrocarbon entrapment and reservoir characteristics. A 3D post-stack time migration seismic cube and logging data of 20 wells were used and several 2D seismic sections were constructed and interpreted. Depth structure maps were generated for the basement reservoir and overlying formations. The top of the basement reservoir is dissected by a set of NW-S…

Stochastic dynamical modelling of spot freight rates

2014

Based on empirical analysis of the Capesize and Panamax indices, we propose different continuous-time stochastic processes to model their dynamics. The models go beyond the standard geometric Brownian motion, and incorporate observed effects like heavy-tailed returns, stochastic volatility and memory. In particular, we suggest stochastic dynamics based on exponential Levy processes with normal inverse Gaussian distributed logarithmic returns. The Barndorff-Nielsen and Shephard stochastic volatility model is shown to capture time-varying volatility in the data. Finally, continuous-time autoregressive processes provide a class of models sufficiently rich to incorporate short-term persistence …

Spatial analysis of the relationship between mortality from cardiovascular and cerebrovascular disease and drinking water hardness

2004

Journal Article; Research Support, Non-U.S. Gov't; Reproduced with permission from Environmental Health Perspectives. Previously published scientific papers have reported a negative correlation between drinking water hardness and cardiovascular mortality. Some ecologic and case-control studies suggest the protective effect of calcium and magnesium concentration in drinking water. In this article we present an analysis of this protective relationship in 538 municipalities of Comunidad Valenciana (Spain) from 1991-1998. We used the Spanish version of the Rapid Inquiry Facility (RIF) developed under the European Environment and Health Information System (EUROHEIS) research project. The strateg…

Gesture recognition using low-cost devices: Techniques, applications, perspectives

2016

Negli ultimi anni abbiamo assistito ad una grande diffusione dei cosiddetti “Kinect-like devices”, ovvero dispositivi basati su un insieme di sensori a basso costo, che consentono di ottenere un’immagine di profondità della scena ripresa. L’alta accessibilità di questi dispositivi, principalmente in termini di costi, ne ha facilitato la diffusione nell’ambito del riconoscimento dei gesti in numerose applicazioni, sia commerciali che di ricerca. In questo articolo saranno inizialmente illustrati i principi generali su cui si fondano le principali tecniche utilizzate per riconoscere i gesti, sfruttando i dati ottenibili dai dispositivi “Kinect-like”. Successivamente, saranno presentati alcuni…

SYSTEMS DECOMPOSITION AND COUPLING

1993

In order to handle efficiently complex models of real systems, it is a convenient practice to decompose them into subsystems that are validated independently. The next step would be joining the subsystems into a global system and performing a new global validation. A formalization of this process is performed as a consequence of practical experience with a model generator expert system based on general systems theory.

Simulation of the anomalous social behaviours with a learning model

2010

In this paper our objective is to understand the process of emergence in the study of social behaviours evolution with a learning model. When the system is too complex to study it is important to recreate an artificial universe in which experiments’ simulation can help to understand the mechanisms of human social behaviours. In Previous work we determined the conditions that favour the perpetuity of the Capitalist Globalization, the possibility of its overcoming with a Free Scientific Society and the possibility of the Ecological Hecatomb. In this paper we have theoretically explained the emergence of the anomalous behaviours and developed statistical studies of the conditions that favour t…

SIMULATING DEMOGRAPHY AND HUMAN DEVELOPMENT DYNAMICS

2014

[EN] A deterministic/stochastic model in which the demographic and the well-being subsystems of a country are involved and related is presented as a way to approach human development. The demographic subsystem is a side-by-side, single-gender, age-structured population dynamic model. The well-being subsystem states the dynamics of the United Nations Hybrid Human Development Index. The model has been validated in the case of Spain and Belgium. Some simulations have been performed with the model for the case of Spain in the 2009-2020 period to determine strategies and scenarios that could increase the life expectancy at birth per gender.

The “I” between G and C: E-Government intermediaries in developing countries

2011

Published version of an article from the journal: The Electronic Journal of Information Systems in Developing Countries. Also available from the publisher: http://www.ejisdc.org/Ojs2/index.php/ejisdc/article/viewFile/826/371 While there has been a rapid growth in e-Government initiatives in developing countries, whether it has led to providing effective government services to the citizens has remained a question of concern. Evidence suggests that this objective is far from being met. The main hurdle has been that an overwhelming part of the citizens in these countries do not have the capability to either access government information physically or to use it effectively even when they can ac…

Social Media as Public Sphere: A Stakeholder Perspective

2016

Purpose This paper aims to examine major stakeholders’ communication preferences in eParticipation initiatives and discuss how this affects the public sphere. Despite the potential of social media, it has proven difficult to get people actively involved in the decision-making processes. There is a need for more research on how stakeholders manage and use social media to communicate. Design/methodology/approach The study was conducted as a qualitative case study. Data sources include interviews, social media content, document analysis and field notes. Findings Communication preferences of stakeholders vary according to their salience level. Stakeholders with higher salience are less likely …
