Is the tourism–economic growth nexus time-varying? Bootstrap rolling-window causality analysis for the top 10 tourist destinations
2017
This article explores the time-varying causal nexus between tourism development and economic growth for the top 10 tourist destinations in the world, namely China, France, Germany, Italy, Mexico, t...
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
Conclusion: Setting Up an Agenda for Life-Course Perspective in International Migration
2018
Each chapter in this book documents ways in which migration is intertwined with life pathways, and tells the story on how migration shapes and is shaped by work, family, and educational pathways. Examples come from a variety of migration flows (Poles in Ireland; Romanians and Moroccans in Italy; Spanish, Portuguese, and Italians in Switzerland), destinations (Spain, Italy, Ireland, Germany), countries of origin (Romania, Morocco, Poland, Spain, etc.), and sources for return migration and/or remigration (Germany, Spain, Italy, Ireland).
Sentiment Analysis of Twitter in Tourism Destinations
2020
[EN] Given the importance of electronic word of mouth (eWOM), this paper analyses the content of messages generated by users related to a tourist destination and shared through Twitter. We propose three research questions regarding eWOM behaviour in Twitter focused on the expertise of the reviewer, sentiment analysis of a tweet and its content.In order to address those research questions we carry out text mining analysis by retrieving existing information on Twitter (over 1500 tweets) regarding to Venice as a tourist destination.
Political Instability, Transnational Tourist Companies and Destination Recovery in the Middle East after 9/11
2007
The change and mobility of images is one of the main forces influencing contemporary tourism. Tourists decide whether to travel to a destination or not on the basis of changing destination images. This is especially true for tourism destinations in the Middle East and North Africa after 9/11. But how do security related destination images affect the actions of the supply side agents? While the impact of incidents of violent political unrest and the consequent changes in destination images on tourist behaviour has been subject to wide academic research, there is a lack of similar studies concerning the supply side. The interdependencies and interactions of transnational hotel companies, loca…
Disruption of apical-basal polarity of human embryonic stem cells enhances hematoendothelial differentiation
2007
Abstract During murine development, the formation of tight junctions and acquisition of polarity are associated with allocation of the blastomeres on the outer surface of the embryo to the trophoblast lineage, whereas the absence of polarization directs cells to the inner cell mass. Here, we report the results of ultrastructural analyses that suggest a similar link between polarization and cell fate in human embryos. In contrast, the five human embryonic stem cell (hESC) lines displayed apical-basal, epithelial-type polarity with electron-dense tight junctions, apical microvilli, and asymmetric distribution of organelles. Consistent with these findings, molecules that are components of tigh…
An eco-label for the airline industry?
2017
Abstract Air travel plays a vital role in today's life because it makes remote destinations accessible and short getaways possible. Despite its benefits, air transportation contributes heavily to climate change. Behavioral change is seen as a key driver in mitigating the environmental impacts of air travel. One way to encourage behavioral change is to use eco-labels. This study explores how an eco-label could be developed for the airline industry to function as a potential driver for behavioral change. 12 interviews with airline industry experts were conducted and thematically analyzed. Empirical results were then combined with prior research and the following five criteria essential for th…
Quantifying submarine groundwater discharge in the coastal zone via multiple methods
2006
Submarine groundwater discharge (SGD) is now recognized as an important pathway between land and sea. As such, this flow may contribute to the biogeochemical and other marine budgets of near-shore waters. These discharges typically display significant spatial and temporal variability making assessments difficult. Groundwater seepage is patchy, diffuse, temporally variable, and may involve multiple aquifers. Thus, the measurement of its magnitude and associated chemical fluxes is a challenging enterprise. A joint project of UNESCO and the International Atomic Energy Agency (IAEA) has examined several methods of SGD assessment and carried out a series of five intercomparison experiments in di…
ENVIRONMENTAL SUSTAINABILITY IN THE MEDITERRANEAN DESTINATIONS: A LATENT CLASS SEGMENTATION ANALYSIS
2016
This article addresses a cross-destination research to study a key issue for the growth and competitiveness of the tourism sector, which is the perceived environmental sustainability of a destination. Particularly, a segmentation analysis is developed to examine potential unobserved heterogeneity across tourists regarding their perception of environmental sustainability of the destination. 918 tourists of five Mediterranean Sea Basin cities are studied using a latent class segmentation technique. Results show the existence of three differentiated latent clusters of tourists with low, medium and high perception of environmental sustainability respectively, confirming the validity of this var…
The Blue Flag Programme AS Pro-Environmental Behaviour Instrument for Coastal Destinations: Towards Municipal Coastal Governance and Communication
2021
The research focuses on evaluation of the Blue Flag programme implementation in Latvia since the year 1998, when the programme’s operations started. It includes analysis and an overview of both the national and local level impacts and the results of the programme implementation. With regard to national level, approach and experience, the overview focuses on effectiveness and the role of the Blue Flag programme as a supporting instrument for successful implementation of environmental legislation. This programme is also analysed as a communication instrument in promoting environmental policies within 500 km long of coastline areas, which in Latvia are announced the national interest territori…
