An Approach for Personalized Social Matching Systems by Using Ant Colony  [PDF]
Luziane Ferreira de Mendona
Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.32013
Abstract:

Personalized social matching systems can be seen as recommender systems that recommend people to others in the social networks, with desirable skills/characteristics. In this work, an algorithm based on Ant Colony is proposed to solve the optimization problem of clustering/matching people in a social network specifically designed for this purpose; during this process, their personal characteristics and preferences (and the degree of importance thereof) are taken into account. The numerical results indicate that the proposed algorithm can successfully perform clustering with a variable number of individuals.

Transparência, condu??o da política monetária e metas para infla??o
Mendona, Helder Ferreira de;
Nova Economia , 2006, DOI: 10.1590/S0103-63512006000100005
Abstract: given that several countries have adopted inflation targeting, and that the main objective of this regime is to function as a guide for the inflationary expectations of economic agents, transparency in the handling of the monetary policy becomes a prerequisite for the success of this regime. this paper presents a survey of the evolution in the theoretical and empirical research concerning transparency in handling monetary policy. the main conclusion suggests that transparency must be understood as a mechanism that, if used in correctly, can favor a rise in credibility in the handling of monetary policy.
Dívida pública e estabilidade de pre?os no período pós-real: explorando rela??es empíricas
Mendona, Helder Ferreira de;
Estudos Econ?micos (S?o Paulo) , 2004, DOI: 10.1590/S0101-41612004000200005
Abstract: the objective of this paper is to study the empirical evidences for the dynamic of the public debt from some variables that are associated with the search for price stability in the period after the introduction of the real plan. for this, a vector autoregression model is made (var) for analyzing the empirical regularities from the relationship among: primary result x public sector borrowing requirements (real interest) x exchange rate x inflation x public debt. the findings denote that the price stability observed in the period is not enough to promote reductions in the public debt and that a new indexation framework is necessary.
Metas para infla??o e taxa de juros no Brasil: uma análise do efeito dos pre?os livres e administrados
Mendona, Helder Ferreira de;
Revista de Economia Política , 2007, DOI: 10.1590/S0101-31572007000300007
Abstract: after surpassed more than half a decade since the adoption of inflation targeting in brazil, it can be seen that maintaining a high interest rate is inherent to the strategy for the conduction of the monetary policy. the objective of this paper is to show that the present policy for defining the basic interest rate of the economy, based on the response to inflation considering both market and administered prices, is onerous for the brazilian society. based on findings from empirical evidence in the period 1999-2004, the adoption of a core inflation, a change in the time horizon for definition of targets, and, in common agreement between banco central do brasil and national treasury, a definition of these inflation targets, as a framework to increase efficiency of the monetary regime, creates possibilities for proposing a reduction on the selic rate.
Inflation bias: an appraisal
Mendona, Helder Ferreira de;
Revista de Economia Política , 2005, DOI: 10.1590/S0101-31572005000200007
Abstract: this short paper offers a brief appraisal of the conventional inflation bias and cukierman's new inflation bias. it may also be seen that a lack of equilibrium in the balance of payments represents another reason for the emergence of the inflationary bias in an economy.
Independência do banco central e equilíbrio fiscal: algumas observa??es para o caso brasileiro
Mendona, Helder Ferreira de;
Revista de Economia Política , 2006, DOI: 10.1590/S0101-31572006000100002
Abstract: the objective of this paper is to analyze the main theoretical arguments for the analysis of the conduction of monetary policy on the fiscal side. besides this, an analysis is made of the possible effects on the fiscal balance from the conduction of the monetary policy in the search for price stability after the real plan and due to an increase in the central bank independence (cbi) in the brazilian case. the findings denote that the strategy for the conduction of the adopted monetary policy and the increase in the degree of cbi did not contribute to an imrovement in the fiscal balance.
Efeitos da independência do banco central e da taxa de rotatividade sobre a infla??o brasileira
Mendona, Helder Ferreira de;
Revista de Economia Política , 2006, DOI: 10.1590/S0101-31572006000400005
Abstract: nowadays, the belief is strong in the brazilian federal government that operational central bank independence is a basic condition to assure price stability. the literature concerning this subject highlights that a high degree of independence and a low turnover of central bank governor are associated with low inflation. this paper analyzes the relation between central bank independence and inflation in brazil during 1980-2002. the findings denote that there is no effect on inflation due to an increase in degree of independence and a fall in turnover rate.

Abstract: central bank transparency: an analysis of the brazilian case. nowadays there is a tendency among central banks of increasing transparency in the conduction of the monetary policy. after the adoption of inflation targeting in brazil there was an increase in the communication of the central bank of brazil with the public. this paper makes a brief review of the recent theoretical and empirical literature concerning this subject. furthermore, an analysis due to the transparency in the conduction of brazilian monetary policy on important macroeconomic variables is made. the findings denote that an increase in transparency improves the behavior of several macroeconomic variables.
