International business tourism : a growth rate model
The aim of this paper is to understand the factors influencing business tourism on a global scale, in
order to assess the competence of the countries in this tourism segment and prescribe them guidelines for
action. For the development of data analysis, a growth rate model was estimated and a sample of 136 countries
for the years 2005 and 2009 was collected. Results reveal that, for the development of policies to stimulate the
growth in the business tourism segment, countries should develop measures that encourage capital investment
in tourism, leisure tourism and trade openness.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de CarvalhoN/
Do neighbouring countries encourage the demand of international business tourism?
This paper aims at determining the factors that influence the growth of international business tourism
and understanding whether the demand growth of business tourism spreads across neighbouring countries. For the development of the empirical research, data has been collected from a sample of 136 countries worldwide, and spatial econometric techniques have been used. Evidence that supports the idea that the main factors related to the increase in incomes of business tourism are the private
investment on tourism assets, the leisure tourism and the trade openness in relation to the outside world is presented. This study also reveals that the demand of business tourism in a country is not contagious, that is, the demand varies neither with the demand of its neighbours nor with their exogenous characteristics. The results have important implications for the choice of tourism policy goals at national levels and the corresponding policy instruments.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de CarvalhoN/
Policies to increase business tourism income : a dynamic panel data model
This article aims to identify the determinants that influence business tourism income and that may be controlled by economic agents and policy makers of destination countries. For the development of the empirical study, a dynamic panel model by the Generalized Method of Moments (GMM) was estimated using the Gretl 2016a software, and a sample of 122 countries for the period 2002?2013 (12 years) was used. The study reveals that, for the development of policies to stimulate the growth in the short
and long-term of business tourism income, countries should develop measures that encourage capital investment in tourism and foreign direct investment.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de CarvalhoN/
Estimation of a growth rate model for international business tourism
The aim of this paper is to understand the factors influencing business tourism on a global scale, in order to assess the competence of the countries in this tourism segment and prescribe them guidelines for action. For the development of data analysis, a growth rate model was estimated and a sample of 136 countries for the years 2005 and 2009 was collected. Results reveal that, for the development of policies to stimulate the growth in the business tourism segment, countries should develop measures that encourage capital investment in tourism, leisure tourism and trade openness. Economic agents should also focus their investments in equipment that creates value throughout the tourism supply chain, in particular, in transport and equipment for entertainment and culture.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de Carvalhoinfo:eu-repo/semantics/publishedVersio
Determinants of competitiveness in international business tourism : an exploratory spatial data analysis
Este artigo tem como objetivo contribuir para a compreens?o dos fatores que influenciam o
turismo de neg?cios ? escala mundial, de forma a avaliar-se a compet?ncia tur?stica dos pa?ses junto
deste segmento e ser-lhes prescrito orienta??es que os auxiliem a conquistar quota de mercado a n?vel
internacional. Para o desenvolvimento da investiga??o emp?rica, foi realizada uma an?lise explorat?ria
de dados espaciais, com recurso ao software OPENGEODA 1.3.15 e recolhida uma amostra de 136
pa?ses mundiais relativos aos anos 2005 e 2009. A investiga??o revela que, para o desenvolvimento de
pol?ticas que visem estimular o crescimento das viagens e turismo de neg?cios, os decisores pol?ticos e
agentes econ?micos, devem desenvolver medidas que estimulem o investimento em capital fixo tur?stico
e o turismo de lazer. Por outro lado, n?o devem tomar em considera??o quest?es de natureza geogr?fica
nas suas decis?es estrat?gicas. No entanto, estas recomenda??es dever?o ser testadas no contexto de
uma futura an?lise confirmat?ria.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de Carvalhoinfo:eu-repo/semantics/publishedVersio
What determines the holding of association meetings in a global context?
This article aims to understand the determinants influencing the number of association meetings held in countries worldwide and which may be controlled by their economic agents and policymakers. For this purpose, we use a dynamic panel model with data provided by the Data World Bank, the World Travel & Tourism Council, and the International Congress and Convention Association, in a time series of 8 years. The results reveal the importance of the experiences obtained by the tourists in previous meetings, as well as the countries? need to implement measures to stimulate the dynamism of economic activity and political stability.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de Carvalhoinfo:eu-repo/semantics/publishedVersio
La influencia del n?mero de delegados sobre el local de las reuniones asociativas internacionales, a nivel nacional : un an?lisis exploratorio de la ?ltima d?cada
Este artigo visa analisar a evolu??o das reuni?es associativas internacionais e do n?mero de delegados das reuni?es associativas internacionais, assim como compreender, de forma explorat?ria, se os planeadores de reuni?es, tendem a ir de encontro aos requisitos esperados pelos principais intervenientes numa reuni?o internacional. Para efeitos da realiza??o do estudo, foi desenvolvida uma an?lise explorat?ria de dados, no per?odo de 2002 a 2009, provenientes da International Congress and Convention Association (ICCA). Os resultados mostram que, os Estados Unidos e a Alemanha lideraram ininterruptamente o ranking de pa?ses com maior n?mero de reuni?es associativas e delegados e, indiciam fortemente que, os planeadores de reuni?es tomam em considera??o os interesses dos executivos das associa??es e dos respetivos participantes, no processo de escolha do local da reuni?o associativa internacional. Os resultados t?m implica??es importantes na postura a adotar pelos delegados e executivos das associa??es, assim como no desenvolvimento de pol?ticas p?blicas.8316-FD77-85EB | Pedro Miguel Fonseca Moreira de CarvalhoN/
Amerindian Ancestry Influences Genetic Susceptibility to Chronic Obstructive Pulmonary Disease
The contribution of genetic ancestry on chronic obstructive pulmonary disease (COPD) predisposition remains unclear. To explore this relationship, we analyzed the associations between 754,159 single nucleotide polymorphisms (SNPs) and risk of COPD (n = 214 cases, 193 healthy controls) in Talca, Chile, considering the genetic ancestry and established risk factors. The proportion of Mapuche ancestry (PMA) was based on a panel of 45 Mapuche reference individuals. Five PRDM15 SNPs and two PPP1R12B SNPs were associate with COPD risk (p = 0.05 to 5x10(-4)) in those individuals with lower PMA. Based on linkage disequilibrium and sliding window analyses, an adjacent PRDM15 SNPs were associated with COPD risk in the lower PMA group (p = 10(-3) to 3.77x10(-8)). Our study is the first to report an association between PPP1R12B and COPD risk, as well as effect modification between ethnicity and PRDM15 SNPs in determining COPD risk. Our results are biologically plausible given that PPP1R12B and PRDM15 are involved in immune dysfunction and autoimmunity, providing mechanistic evidence for COPD pathogenesis and highlighting the importance to conduct more genome wide association studies (GWAS) in admixed populations with Amerindian descent
Recent developments of the Hierarchical Reference Theory of Fluids and its relation to the Renormalization Group
The Hierarchical Reference Theory (HRT) of fluids is a general framework for
the description of phase transitions in microscopic models of classical and
quantum statistical physics. The foundations of HRT are briefly reviewed in a
self-consistent formulation which includes both the original sharp cut-off
procedure and the smooth cut-off implementation, which has been recently
investigated. The critical properties of HRT are summarized, together with the
behavior of the theory at first order phase transitions. However, the emphasis
of this presentation is on the close relationship between HRT and non
perturbative renormalization group methods, as well as on recent
generalizations of HRT to microscopic models of interest in soft matter and
quantum many body physics.Comment: 17 pages, 5 figures. Review paper to appear in Molecular Physic
