Evolución histórica de la autonomía de la voluntad en el Derecho matrimonial
2021
The autonomy of the will or power of self-regulation of relationships derived from marriage is a subject that is on the rise and that we can qualify as novel. More and more couples are opting to proceed making use of this power to self-regulate both personal and property effects derived from their union or its future breakdown. In the Spanish legal system there is no precise and complete regulation of the subject, without all these figures being equally legislated, although all are admitted without any doubt by jurisprudence. In recent years there has been an evolution of Family law, traditionally very reluctant to give space to self-regulation. Our Constitution marks a turning point by cha…
An Efficient and Secure Energy Trading Approach with Machine Learning Technique and Consortium Blockchain
2022
In this paper, a secure energy trading mechanism based on blockchain technology is proposed. The proposed model deals with energy trading problems such as insecure energy trading and inefficient charging mechanisms for electric vehicles (EVs) in a vehicular energy network (VEN). EVs face two major problems: finding an optimal charging station and calculating the exact amount of energy required to reach the selected charging station. Moreover, in traditional trading approaches, centralized parties are involved in energy trading, which leads to various issues such as increased computational cost, increased computational delay, data tempering and a single point of failure. Furthermore, EVs fac…
A simple model of income, aggregate demand and the process of credit creation by private banks
2013
This paper presents a small macroeconomic model describing the main mechanisms of the process of creation by the private banking system. The model is composed of a core unit-where the dynamics of income, credit and aggregate demand are determined-and a set of sectoral accounts that ensure its stock-flow consistency. In order to grasp the role of credit and banks on the functioning of the economic system we make an explicit distinction between planned and realized variables, thanks to which, while maintaining the ex-post accounting consistency, we are able to introduce an ex-ante wedge between current aggregate income and planned expenditure. Private banks are the only economic agents capabl…
The effect of the great recession on foreign direct investment: global empirical evidence with a gravity approach
2013
This article estimates the effect of the present global systemic banking crisis on foreign direct investment (FDI) using the gravity equation on a sample of 161 countries over the period 2003 to 2010. Systemic banking crises, through demand shocks and credit constraints, may impact FDI in two ways: aggregate monetary flows and individual projects count. Since gravity equations account for output variations, our research relies on the financial constraints channel. We find that the great recession, through credit constraints on home supply markets, has reduced the number of FDI projects, but not their size, forcing investors to become more selective on their international endeavours.
The macroeconomic effects of public investment: Evidence from advanced economies
2015
This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting ou…
From endogenous growth to stationary state: The world economy in the mathematical formulation of the Ricardian system
2016
AbstractWe analyse international trade in a Pasinetti–Ricardo growth model in the world economy scenario in which several small trading countries coexist and international commodity prices are determined by the interplay of supply and demand amongst them. We demonstrate that all the trading countries eventually reach the stationary state, though this process is not monotonic and the dynamics of capital and population may actually push some countries towards the stationary state and others away from it. We also use our model to assess an argument which Malthus employed in the second edition of An Essay on the Principle of Population (1803) to support a policy of agricultural protectionism.
Application of screening tools to detect risk of hospital readmission in elderly patients in Valencian Healthcare System (VHS) (Spain).
2013
Abstract The Sustainable Social and Healthcare Model (SSHM) is aimed to establish new care pathways in primary care systems contributing to the decrease of health services use and costs and improve the integration and efficiency of social and health care for elderly people with long-term care (LTC) needs. One of these strategies is the segmentation of population in risk groups through standardized tools. This paper is a retrospective study aimed to determine the viability of the implementation of the screening tools Probability of Repeated Admission – Pra – and The Community Assessment Risk Screen – CARS – to detect patients at risk of hospital readmission in a sample of 500 elderly people …
Incentive and Selection Effects of Medigap Insurance on Inpatient Care
2012
The Medicare program, which provides insurance coverage to the elderly in the United States, does not protect them fully against high out-of-pocket costs. For this reason private supplementary insurance, named Medigap, has been available to cover Medicare gaps. This paper studies how Medigap affects the utilization of inpatient care, separating the incentive and selection effects of supplementary insurance. For this purpose, we use two alternative estimation methods: a standard recursive bivariate probit and a discrete multivariate finite mixture model. We find that estimated incentive effects are modest and quite similar across models. On the other hand, there seems to be very significant …
A comparison of the dental status and treatment needs of older adults with and without chronic mental illness in Sevilla, Spain
2012
Objectives: To study the dental status and treatment needs of institutionalized older adults with chronic mental illness compared to a non-psychiatric control sample. Study Design: The sample size was 100, in which 50 were psychogeriatric patients (study group; SG) classified according to DSM-IV, with a mean age of 69.6 ± 6.7 years, and 50 non-psychiatric patients (control group; CG), with a mean age of 68.3 ± 6.9 years. Clinical oral health examinations were conducted and caries were recorded clinically using the Decayed, Missing and Filled Teeth Index (DMFT). Results were analyzed statistically using the Student’s t-test or analysis of variance. Results: Caries prevalence was 58% and 62% …
White Paper of Italian Gastroenterology: Delivery of services for digestive diseases in Italy: Weaknesses and strengths
2014
In 2011 the three major Italian gastroenterological scientific societies (AIGO, the Italian Society of Hospital Gastroenterologists and Endoscopists; SIED, the Italian Society of Endoscopy; SIGE, the Italian Society of Gastroenterology) prepared their official document aimed at analysing medical care for digestive diseases in Italy, on the basis of national and regional data (Health Ministry and Lombardia, Veneto, Emilia-Romagna databases) and to make proposals for planning of care. Digestive diseases were the first or second cause of hospitalizations in Italy in 1999–2009, with more than 1,500,000 admissions/year; however only 5–9% of these admissions was in specialized Gastroenterology un…
