The international debt problem: An analysis of the Brady plan

1989

Recently the American Treasury Secretary, Nicholas Brady, launched a new initiative in which he proposed reducing the developing countries’ bank debt. What are the elements of the plan, and which countries would benefit? What problems does it entail? Can it bring about a decisive improvement in the international debt situation of the developing countries? The following two articles attempt to answer these questions.

Future directions in international financial integration research - A crowdsourced perspective

2018

This paper is the result of a crowdsourced effort to surface perspectives on the present and future direction of international finance. The authors are researchers in financial economics who attended the INFINITI 2017 conference in the University of Valencia in June 2017 and who participated in the crowdsourcing via the Overleaf platform. This paper highlights the actual state of scientific knowledge in a multitude of fields in finance and proposes different directions for future research.

The impact of the financial crisis on financial integration, growth and investment

2012

Financial crises, and in particular those of the past few years, have severe consequences for the affected economies. In this paper we analyse the impact of financial development and European financial integration on growth and we find no reversal of the growth benefits of financial development and integration in recent years. This highlights the economic cost of regulatory changes that would reverse European financial integration. We also find that, following a financial crisis, investment declines more in countries with a greater degree of uncertainty aversion, which can be informative for evaluating post-crisis economic performance.

Poincaré inequalities and Steiner symmetrization

1996

A complete geometric characterization for a general Steiner symmetric domain Ω ⊂ Rn to satisfy the Poincare inequality with exponent p > n−1 is obtained and it is shown that this range of exponents is best possible. In the case where the Steiner symmetric domain is determined by revolving the graph of a Lipschitz continuous function, it is shown that the preceding characterization works for all p > 1 and furthermore for such domains a geometric characterization for a more general Sobolev–Poincare inequality to hold is given. Although the operation of Steiner symmetrization need not always preserve a Poincare inequality, a general class of domains is given for which Poincare inequalities are…

On the first return integrals

2007

Some pathological properties of the first-return integrals are explored. In particular it is proved that there exist Riemann improper integrable functions which are first-return recoverable almost everywhere, but not first-return integrable, with respect to each trajectory. It is also proved that the usual convergence theorems fail to be true for the first-return integrals.

Prediction and Surveillance Sampling Assessment in Plant Nurseries and Fields

2022

In this paper, we propose a structured additive regression (STAR) model for modeling the occurrence of a disease in fields or nurseries. The methodological approach involves a Gaussian field (GF) affected by a spatial process represented by an approximation to a Gaussian Markov random field (GMRF). This modeling allows the building of maps with prediction probabilities regarding the presence of a disease in plants using Bayesian kriging. The advantage of this modeling is its computational benefit when compared with known spatial hierarchical models and with the Bayesian inference based on Markov chain Monte Carlo (MCMC) methods. Inference through the use of the integrated nested Laplace app…

Robustness, Stability, and Fidelity of Explanations for a Deep Skin Cancer Classification Model

2022

Skin cancer is one of the most prevalent of all cancers. Because of its being widespread and externally observable, there is a potential that machine learning models integrated into artificial intelligence systems will allow self-screening and automatic analysis in the future. Especially, the recent success of various deep machine learning models shows promise that, in the future, patients could self-analyse their external signs of skin cancer by uploading pictures of these signs to an artificial intelligence system, which runs such a deep learning model and returns the classification results. However, both patients and dermatologists, who might use such a system to aid their work, need to …

Minori stranieri non accompagnanti: abilità, risorse e competenze

2019

L’apprendimento dell’italiano per i minori stranieri non accompagnati procede a passi relativamente rapidi anche se i ragazzi intervistati hanno una scarsa scolarità. L’età relativamente giovane, insieme a una esperienza di vita del tutto particolare, che li ha fatti crescere forzosamente, deve avere reso questi ragazzi particolarmente ricettivi nei confronti dell’apprendimento della lingua. D’altra parte, essa si presenta, ai loro occhi, come la porta principale di accesso a una condizione di vita che non può che essere migliore di quella che hanno lasciato e che, in ogni caso, offre loro la convinzione di avere più prospettive di vita e di riuscita di quelle che hanno lasciato nel paese d…

Alternative boundary integral equations for fracture mechanics in 2D anisotropic bodies

2017

An alternative dual boundary element formulation for generally anisotropic linear elastic twodimensional bodies is presented in this contribution. The formulation is based on the decomposition of the displacement field into the sum of a vector field satisfying the anisotropic Laplace equation and the gradient of the classic Airy stress function. By suitable manipulation of the integral representation of the anisotropic Laplace equation, a set of alternative integral equations is obtained, which can be used in combination with the displacement boundary integral equation for the solution of crack problems. Such boundary integral equations have the advantage of avoiding hyper-singular integral…
