Tourism destination development: economic impacts evaluation due to intercultural food festivals

2014

The design and realization of events has become a relevant activity because it can accelerate the growth of European tourist destinations. Events provide a new demand for goods and services, which, in addition to local consumption, leads to an increase in revenues and employment. Moreover, when an event becomes an attractor, it generates new motivations for visiting a destination in addition to the traditional ones, which are generally linked to the presence of natural resources. While the issue can rely on extensive literature today, it established itself only at the end of the last century. Many authors have addressed the issue of the economic impact of events, amongst whom Grado, Strauss…

Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis

2014

Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…

Evaluating Socio-economic Impact of Age-Friendly Environments

2018

According to the World Health Organization (WHO) (2007), physical and social environments are key determinants of whether people can remain healthy, independent and autonomous. Health and well-being are not only determined by our personal characteristics but also by the envi-ronment where we were born and where we live throughout our life (WHO 2015). In fact, promoting age-friendly environments (AFE) is the most effective approach for responding to demographic change because they empower elderly people to age in better health, they pro-mote their social inclusion and active participation, and they help them to live autonomously into old age (Parent 2012). AFE foster health, well-being and t…

Life cycle energy and environmental impacts of a solid oxide fuel cell micro-CHP system for residential application

2019

Abstract Fuel cells are considered one of the key technologies to reach the ambitious European goal of a low carbon economy, by reducing CO2 emissions and limiting the production of other pollutants. The manuscript presents an assessment of the life cycle energy and environmental performances of a solid oxide fuel cell system for household applications using primary data from the manufacturing phase and experimental data for the start-up and operation phases. The Life Cycle Assessment methodology is applied, based on a functional unit of 1 MJ of exergy and includes the life cycle steps from the raw materials extraction to the maintenance. The results show a particular relevance of the opera…

G-Spaces and Kaluza-Klein Theory

1988

G-spaces are present whenever symmetries are relevant in physics. After a short introduction to this subject, spontaneous symmetry breaking in elementary particle physics is considered from this point of view. Kaluza-Klein theory is discussed in a purely geometrical formulation. Some results in connection with the geometrical compactification scheme are presented.

Processing and mechanical properties of organic filer-polypropylene composites

2005

The addition of organic fillers into thermoplastic polymers is an interesting issue, which has had growing consideration and experimentation during the last years. It can give rise to several advantages. First, the cost of these fillers is usually very low. Also, the organic fillers are biodegradable (thus contributing to an improved environmental impact), and finally, some mechanical and thermomechanical properties can be enhanced. In this study, the effect of the addition of different organic fillers on the mechanical properties and processability of an extrusion-grade polypropylene were investigated. The organic fillers came from natural sources (wood, kenaf, and sago) and were compared …

The evolution of market power in European banking

2017

This paper analyses the effect that European financial market integration has had on the evolution of the banks' market power disparities. The results show that market power disparity has narrowed among eurozone banks. The reduction is attributable to the convergence in the average levels of market power of the European banking sectors. In contrast, the disparities observed within each country have remained stable. As a result, the measures adopted to advance towards a single banking market should be complemented by measures at the national level designed to intensify competition among the banks within a given country.

How markets slowly digest changes in supply and demand

2008

In this article we revisit the classic problem of tatonnement in price formation from a microstructure point of view, reviewing a recent body of theoretical and empirical work explaining how fluctuations in supply and demand are slowly incorporated into prices. Because revealed market liquidity is extremely low, large orders to buy or sell can only be traded incrementally, over periods of time as long as months. As a result order flow is a highly persistent long-memory process. Maintaining compatibility with market efficiency has profound consequences on price formation, on the dynamics of liquidity, and on the nature of impact. We review a body of theory that makes detailed quantitative pr…

Firms’ investment, indebtedness and financial constraints: Size does matter

2022

Abstract This paper provides evidence of the importance of size in explaining the impact of financing conditions on firms´ investment rate. The study makes two main contributions: a) it allows the relationship between indebtedness and firms´ investment to be non-linear; and b) it contrasts whether the impact of indebtedness and the degree of financial restriction differ depending on the size of the company (SME vs large). Results show that while in SMEs indebtedness has a negative impact on investment, there is a threshold beyond which this effect is even larger (based on a debt/assets ratio of 59%). However, in large companies the impact of indebtedness is positive although there is also a…
