Algebraic models of the real affine plane

2017

We introduce a new invariant, the real (logarithmic)-Kodaira dimension, that allows to distinguish smooth real algebraic surfaces up to birational diffeomorphism. As an application, we construct infinite families of smooth rational real algebraic surfaces with trivial homology groups, whose real loci are diffeomorphic to $\mathbb{R}^2$, but which are pairwise not birationally diffeomorphic. There are thus infinitely many non-trivial models of the real affine plane, contrary to the compact case.

Responsible Investment: Taxes and Paradoxes

2017

Abstract Taxes have become an issue of corporate social responsibility (CSR), but the role of taxation is to some extent an ambiguous and controversial issue in the CSR framework. Similarly, another unclear question is what role investors who are committed to sustainable and responsible investment (SRI) see taxes as having on their environmental, social, and governance (ESG) agenda. Corporate taxes have an inverse relationship with the return of the investors: taxes paid directly affect what is left on the bottom line, reducing the return of investors. However, investors are now more aware of tax-related risks, which can include different forms of reputation risk. Corporate tax planning may…

Estimating regional differences in returns to education when schooling and location are determined endogenously

2010

While the growing supply of university skills is known to have agglomerated towards the large centers in Finland, there is no research knowledge available on the development of regional demands. This paper attempts to fill this gap by analyzing regional variation in the private-sector return to university education in Finland for the period 1970 - 2004. In the analysis, we focus on studying 1) whether there are differences in the return to university between different region types, and 2) to what extent can these differences - if they exist - be explained by differences in regional skill supply and unemployment. For the econometric analysis, we use a large register-based dataset constructed…

THE NEED FOR THE BALANCE BETWEEN WORK AND PERSONAL LIFE IN THE CONTEXT OF ECONOMIC CRISIS AND THE ENHANCE QUALITY OF LIFE

2012

The professional life of the individual in society should become a major goal of the employment policies and strategies, a goal considered science and art. Starting from the Europe`s demographic paradox, it is concluded the need to use at full capacity the human resources of the EU27, by maximizing the efficiency of each individual of the society. Based on criteria of choice a caree and of the satisfaction - productivity report it is detailed the importance of counselling to optimize the relationship skills / utility in the society. In the end, a series of conclusions and suggestions are presented on the current and future way of addressing employment, education, continuous lifelong profess…

Le cadre de sante entre logiques d'utilité économique et logiques de soins hospitaliers

2010

The public hospital first line manager has to organize the activity of his care unit on the basis of arbitrations between two systems of logic that come more and more frequently in conflict: - The market logic / the public hospital logic - The care process logic / the patient's path logic - The function logic / the professional logic - The managerial logic / the logic "bureaucratic"

Multi-parameter analysis of the obstacle scattering problem

2022

Abstract We consider the acoustic field scattered by a bounded impenetrable obstacle and we study its dependence upon a certain set of parameters. As usual, the problem is modeled by an exterior Dirichlet problem for the Helmholtz equation Δu + k 2 u = 0. We show that the solution u and its far field pattern u ∞ depend real analytically on the shape of the obstacle, the wave number k, and the Dirichlet datum. We also prove a similar result for the corresponding Dirichlet-to-Neumann map.

MODELLING AND SIMULATING RISKS IN THE TRAINING OF THE HUMAN RESOURCES BY APPLYING THE CHAOS THEORY

2012

The article approaches the modelling and simulation of risks in the training of the human resources, as well as the forecast of the degree of human resources training impacted by risks by applying the mathematical tools offered by the Chaos Theory and mathematical statistics. We will highlight that the level of knowledge, skills and abilities of the human resources from an organization are autocorrelated in time and they depend on the level of a previous moment of the training, as well as on the impact of the risk factors that can materialize in the process of the continuous training of human resources. The process of self-correlation and continuous training ensures the sustainable and qual…

Back to the Future: Migration, Matching and the Power Couple Phenomenon in Sweden

2014

This paper contributes to a recent and growing literature addressing the phenomenon of high-credentialed power couples. It seeks to determine the extent to which precursors of power couple formation and location choice of couples at midlife are evident in young people during their formative school years. Its second objective is to extend the analysis of location choice by modeling location choice among different sizes of labor market areas, given different power status of the couples. Based on analysis of Swedish register data, we produce evidence that power spouses evolve from the population of high achieving school age individuals, the latter identified by high academic performance during…

Work incentive and productivity in Spain

2013

Work incentives are closely related to production performance. This paper presents evidence that the value added of a firm increases when relative labor costs rise, or the level of unemployment increases. Both circumstances imply evidence in favor of the efficiency wage model. This theory is consistent with the views of many managers and personal administrators, who tend to ascribe primary importance to wage setting as an incentive to increase effort. We use a micro panel data set of Spanish manufacturing firms, during the period 2004–2009, to simultaneously estimate a stochastic frontier of a firm’s value added and the inefficiency determinants. The data source is published in the Spanish …

Diversidad de género, igualdad de oportunidades y entornos laborales

2004

Gender diversity can be considered a useful strategy for improving equal opportunities in the labour market. It is also a valid criterion for optimising human resources in management professions. Unlike other strategies for promoting equal opportunities that have been applied in political or social spheres (quota system, parity representation, etc.), gender diversity combines humanitarian criteria based on citizenship rights for women with maximalist arguments relating to the value such a strategy can add to labour organisations. The Divers@: género y diversidad project lays down a working method and operational model for analysing possible imbalance caused by the specific gender diversity …
