An Application of Clustering Analysis to International Private Indebtedness

This paper presents a procedure for clustering analysis that combines Kohone’s Self organizing Feature Map (SOFM) and statistical schemes. The idea is to cluster the data in two stages: run SOFM and then minimize the segmentation dispersion. The advantages of proposed procedure will be illustrated through a synthetic experiment and a real macroeconomic problem. The procedure is then used to explore the relationship between private indebtedness and some macroeconomic variables commonly used to measure macroeconomic performance. The experiences of thirty-nine countries in the early nineties are analyzed. The procedure outperformed others clustering techniques in the job of identifying consistent groups of countries from the economic and statistical viewpoints. It found out similarities in different countries concerning their respective levels of private indebtedness when added to well accepted parameters to measure macroeconomic performance.Vector quantization, Clustering, Self-Organizing Feature Map,Macroeconomic Performance, Private Indebtedness.

A geometric construction of a Calabi quasimorphism on projective space

We use the rotation numbers defined by Théret in [T] to construct a quasimorphism on the universal cover of the Hamiltonian group of CP^n. We also show that this quasimorphism agrees with the Calabi invariant for isotopies that are supported in displaceable subsets of CP^n

Terra sigillata hispânica tardia do concelho de Fronteira: exemplares recolhidos entre 1999 e 2003

Divulga-se um fabrico cerâmico insuficientemente conhecido no território português. Tendo sido recolhido em vários sítios arqueológicos no concelho de Fronteira, os autores apresentam os fragmentos recolhidos de terra sigillata hispânica tardia e esboçam um mapa de distribuição da referida produção para os arqueossítios romanos em Portugal

Does Inflation Targeting Matter for Output Growth? Evidence from Industrial and Emerging Economies

This paper examines the effects of inflation targeting on industrial and emerging economies' output growth over the "globalization years" of 1986-2004. Controlling for trade openness and two indicators of financial globalization, the authors find systematic positive and significant effects of inflation targeting on real output growth. In dynamic models, the findings show strong output persistence in industrial economies, in which partial and full inflation targeting regimes have a positive long-run impact on growth. In emerging markets, only full inflation targeting policies have any output effect in the long-run. The results suggest that strict inflation targeting is needed to make the discipline effect of the disinflation process outweigh the output costs of promoting high interest rates to attract capital flows in a global world. These findings are robust to the treatment of endogenous globalization measures.Economic Growth; Globalization; Inflation Targeting; Panel Data Methods

The fate of villae: the example of Horta da Torre (Fronteira).

The excavations carried out at the Roman villa of Horta da Torre since 2012 have documented an interesting process of post-abandonment reoccupation and systematic destruction of the built space. Though archaeological evidence can sometimes be tenuous, it records a concrete case of occasional reoccupations, while parallel circumstances have also been detected at various archaeological sites in Lusitania and other areas of Hispania. Evidence has been found to suggest that Horta da Torre was a location at which yet another phenomenon occurred, during which monumental structures and ways of living in the countryside in the imperial era were disrupted, thus allowing for questions about subsistence strategies in the post-classical period to be posed

Real time analytics for characterizing the computer user's state

In the last years, the amount of devices that can be connected to a network grew significantly allowing to, among other tasks, collect data about the environment or the people in it in a non-intrusive way. This generated nowadays well-known topics such as Big Data or the Internet of Things. This also opened the door to the development of novel and interesting applications. In this paper we propose a distributed system for acquiring data about the users of technological devices in a non-intrusive way. We describe how this data can be collected and transformed to produce meaningful interaction features, that reveal the state of the individuals. We analyse the requirements of such a system, namely in terms of storage and speed, and describe three prototypes currently being used in three different domains of application.- This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT - Fundacao para a Ciencia e Tecnologia within the Project Scope: UID/CEC/00319/2013.info:eu-repo/semantics/publishedVersio

Inflation Targeting and Exchange Rate Volatility in Emerging Markets

The paper investigates the exchange rate on the reaction function of 24 emerging markets economies’ (EMEs) central banks from 2000Q1 to 2015Q2. This is done by first employing fixed-effects (FE) ordinary least squares and then system generalized methods of the moments techniques. Under FE, the exchange rate is important in the reaction function of EMEs. Allowing for the endogeneity of inflation, output gap, and the exchange rate, the exchange rate remains positive and statistically significant (but quantitatively less) across inflation targeting countries. When the sample is partitioned into targeting and non-targeting countries, the exchange rate remains relevant in the reaction function of non-targeters. The results remain robust to splitting the sample at the time of the financial crisis of 2007–2009 and suggest that, after the crisis, central banks of EMEs respond only to inflation movements in the interest rate reaction function
