Percepción de los residentes sobre los impactos de un gran evento deportivo: Desarrollo y validación de una escala
2017
Esta tesis doctoral desarrolla y valida una escala para analizar el impacto social de los eventos deportivos en la población española. Asimismo, se analiza el impacto social de un gran evento deportivo como es el Gran Premio de Europa de Fórmula 1 celebrado entre los años 2008 y 2012 en la ciudad de Valencia. Por lo tanto, este estudio tiene tres objetivos generales: en primer lugar, desarrollar y validar una escala para analizar la percepción de los residentes sobre los impactos asociados a la celebración de un gran evento deportivo; segundo, comprobar la validez de la escala para conocer las percepciones de los residentes sobre el Gran Premio de Europa de Fórmula 1; y, tercero, conocer la…
Effects of Central and Peripheral Fatigue on Impact Characteristics during Running.
2022
Fatigue and impact can represent an injury risk factor during running. The objective of this study was to compare the impact transmission along the locomotor system between the central and peripheral fatigued states during running. Tibial and head acceleration as well as shock attenuation in the time- and frequency-domain were analyzed during 2-min of treadmill running in the pre- and post-fatigue state in eighteen male popular runners (N = 18). The impact transmission was measured before and after a 30-min central fatigue protocol on the treadmill or a peripheral fatigue protocol in the quadricep and hamstring muscles using an isokinetic dynamometer. The time-domain acceleration variables …
Residents’ Perception of the Impact of Sports Tourism on Sustainable Social Development
2022
The analysis of the social perception of citizens and evaluations of the impact of sport tourism and their support for tourism development can be of great use in the formulation of policies aimed at social cohesion and local development. These actions favor social participation and inclusion, equal opportunities, and more positive attitudes towards sports tourism and inclusive sport. This study aims to analyze the perception and predisposition towards the support of citizens on the impact of sport tourism from a multidimensional perspective. Specifically, this study evaluates the social perception on four measures: social impact, cultural impact, environmental impact, and local policies. Th…
The economic impact of migration: productivity analysis for Spain and the UK
2012
Over the past 20 years labour has become increasingly mobile and whilst employment and earnings effects in host countries have been extensively analysed, the implications for firm and industry performance have received far less attention. This paper explores the direct economic consequences of immigration on host nations’ productivity performance at a sectoral level in two very different European countries, Spain and the UK. Whilst the UK has traditionally seen substantial immigration, for Spain the phenomenon is much more recent. Our findings from a growth accounting analysis show that migration has made a negative contribution to labour productivity growth in Spain and a negative but negl…
The impact of embassies and consulates on tourism
2007
Abstract This paper estimates the effect of embassies and consulates on tourist flows from the G-7 countries. The results indicate that embassies and consulates have a positive and significant effect on tourism that ranges between 15% and 30% depending on the estimation technique. Moreover, the impact is larger for the sample of developing countries. The disaggregated analysis shows that, after controlling for both origin and destination fixed effects, a significant impact is found in the seven origin countries.
Trace element mobility during interaction between rain and volcanic ash on Mt. Etna
2012
Volcanic emissions represent one of the most relevant natural sources of trace elements to the troposphere, both during and between eruptions. Due to their potential toxicity they may have important environmental impacts from the local to the global scale. Atmospheric precipitation was collected approximately every two weeks, from April 2006 to December 2007, using a network of five rain gauges, located at various altitudes on the upper flanks around the summit craters of Etna volcano. The collected samples were analysed for major (Ca, Mg, K, Na, F, SO4, Cl, NO3) and a large suite of trace elements (Ag, Al, As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cs, Cu, Fe, Hg, La, Li, Mn, Mo, Ni, Pb, Rb, Si, S…
Volcanic plume monitoring at mount Etna by diffusive(passive)sampling
2004
This paper reports the use of diffusive tubes in determining HF, HCI, and SO2 in the volcanic plume of Mount Etna in an attempt to highlight the potential of this method in studying volcanoes. In a first application a network of 18 diffusive tubes was installed on Etna's flanks, aimed at evaluating the atmospheric dispersion of the volcanic plume on a local scale. Results showed a monotonic decrease in volatile air concentrations with distance from the craters (HF from 0.15 to <0.003 μmol m-3 , HCl from 2 to <0.01 μmol m -3, and SO2 from 11 to 0.04 μmol m -3 ), revealing the prevalently volcanic contribution. Matching of SO2/HCl and HCl/HF volatile ratios with contemporaneous measurements a…
Patterns in the recent 2007-2008 activity of Mount Etna volcano investigated by integrated geophysical and geochemical observations
2010
[1] Seismic, deformation, and volcanic gas observations offer independent and complementary information on the activity state and dynamics of quiescent and eruptive volcanoes and thus all contribute to volcanic risk assessment. In spite of their wide use, there have been only a few efforts to systematically integrate and compare the results of these different monitoring techniques. Here we combine seismic (volcanic tremor and long-period seismicity), deformation (GPS), and geochemical (volcanic gas plume CO2/SO2 ratios) measurements in an attempt to interpret trends in the recent (2007–2008) activity of Etna volcano. We show that each eruptive episode occurring at the Southeast Crater (SEC)…
Eudontomyzon danfordi (Regan, 1911) Species Populations Ecological Status in Maramureş Mountains Nature Park (Romania)
2015
Abstract The Eudontomyzon danfordi characteristic habitats state of Maramureş Mountains Nature Park varies greatly, 19.05% are in excellent conservation status, 47.62% are in good/average status and 33.33% are in a partially degraded condition. The identified human impact categories which induced the decreasing of Eudontomyzon danfordi species habitat state in the studied area are: poaching, minor riverbeds morphodynamic changings, liquid and solid natural flow disruption, destruction of riparian trees and bush vegetation, habitat fragmentation-fish populations isolation, and organic/mining pollution activities.
Debating Europe: Effects of the “Eurovision Debate” on EU Attitudes of Young German Voters and the Moderating Role Played by Political Involvement
2016
In the run-up to the elections to the European Parliament in 2014, EU citizens had the unprecedented opportunity to watch televised debates between the candidates running for president of the European Commission. The most important debate was the so-called "Eurovision debate", which was broadcasted in almost all EU member states. In this study we explore the responses of a sample of 110 young German voters, who watched this debate, to the candidates' messages and whether exposure to the debate caused a shift in the respondents' attitudes towards the EU. Combining data from a quasi-experiment, real-time response data, and data from a content analysis of the debate, we find that respondents' …
