Comparative analysis of the European Union crowdfunding service providers regulation and regulatory barriers for crowdfunding in the Baltic States
2021
The issue of conflicting national frameworks on crowdfunding and dispersed structures of investors and products has drawn significant attention in the European Union. Some Member States introduced national rules to regulate their crowdfunding platforms, while others left some aspects of the activity unregulated. This variation of national licensing, diverging definitions of business models and application of existing EU legislation are considered to contribute to crowdfunding market fragmentation. Some surveys demonstrate that crowdfunding regulatory heterogeneity in the Member States negatively affects the market. In the paper, this heterogeneity is revised on the example of Latvia, Lithua…
The two-track Europeanization of football: EU-level pressures, transnational dynamics and their repercussions within different national contexts
2012
This article contributes to the under-researched literature on the Europeanization of sports. We distinguish between two modes of Europeanization (broadly signifying the impact of European integration on the domestic realm): the traditional top-down approach and the neglected societal/transnational Europeanization track. Both modes are examined with regard to their effects within two national contexts (Germany and Austria), and across two cases: the Bosman ruling (the nationality issue) and European club competitions as an engine of Europeanization. Our analysis reveals some important differences: the domestic countermeasures regarding the nationality aspect of the Bosman ruling were more s…
Counterdispositional Conscientiousness and Wellbeing: How Does Acting Out of Character Relate to Positive and Negative Affect at Work?
2020
Conscientiousness is typically seen as a positive or desired personality trait in the workplace, with the overall assumption being “the more, the better”. Drawing on the behavioral concordance model, we challenge this assumption, expecting that the highest level of positive affect and the lowest level of negative affect will correspond at the point where state and trait conscientiousness converge. Using an experience sampling study and an event reconstruction study, we show that deviations from one’s level of trait conscientiousness relate to variations in positive and negative affect, but not in a straightforward way. While wellbeing was lower when people behaved less conscientiously than …
Main well-being factors in tourism context : an application to active sport tourism
2021
La quête du bien-être représente l’un des moteurs des comportements humains, cette quête s’observant particulièrement dans le tourisme qui est considéré comme une activité qui le procure. Cependant, les causes du bien-être ne sont pas encore parfaitement appréhendées. Cet article a pour objectif d’identifier les principaux facteurs susceptibles de contribuer au bien-être vécu dans un cadre touristique en mobilisant le champ de la psychologie positive et celui du comportement du consommateur et, au-delà, du marketing. Dans un premier temps, les apports de la psychologie positive à l’analyse du bien-être seront exposés et, dans un deuxième temps, un modèle intégrateur des facteurs du bien-êtr…

Physiological advantages of dwarfing in surviving extinctions in high-CO2 oceans
2015
Excessive CO 2 in the present-day ocean-atmosphere system is causing ocean acidification, and is likely to cause a severe biodiversity decline in the future, mirroring effects in many past mass extinctions. Fossil records demonstrate that organisms surviving such events were often smaller than those before, a phenomenon called the Lilliput effect. Here, we show that two gastropod species adapted to acidified seawater at shallow-water CO 2 seeps were smaller than those found in normal pH conditions and had higher mass-specific energy consumption but significantly lower whole-animal metabolic energy demand. These physiological changes allowed the animals to maintain calcification and to parti…

ISARIC-COVID-19 dataset: A Prospective, Standardized, Global Dataset of Patients Hospitalized with COVID-19
2022
The International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) COVID-19 dataset is one of the largest international databases of prospectively collected clinical data on people hospitalized with COVID-19. This dataset was compiled during the COVID-19 pandemic by a network of hospitals that collect data using the ISARIC-World Health Organization Clinical Characterization Protocol and data tools. The database includes data from more than 705,000 patients, collected in more than 60 countries and 1,500 centres worldwide. Patient data are available from acute hospital admissions with COVID-19 and outpatient follow-ups. The data include signs and symptoms, pre-existing como…
Estimation of causal effects with small data in the presence of trapdoor variables
2021
We consider the problem of estimating causal effects of interventions from observational data when well-known back-door and front-door adjustments are not applicable. We show that when an identifiable causal effect is subject to an implicit functional constraint that is not deducible from conditional independence relations, the estimator of the causal effect can exhibit bias in small samples. This bias is related to variables that we call trapdoor variables. We use simulated data to study different strategies to account for trapdoor variables and suggest how the related trapdoor bias might be minimized. The importance of trapdoor variables in causal effect estimation is illustrated with rea…
Conditional Bias Robust Estimation of the Total of Curve Data by Sampling in a Finite Population: An Illustration on Electricity Load Curves
2020
Abstract For marketing or power grid management purposes, many studies based on the analysis of total electricity consumption curves of groups of customers are now carried out by electricity companies. Aggregated totals or mean load curves are estimated using individual curves measured at fine time grid and collected according to some sampling design. Due to the skewness of the distribution of electricity consumptions, these samples often contain outlying curves which may have an important impact on the usual estimation procedures. We introduce several robust estimators of the total consumption curve which are not sensitive to such outlying curves. These estimators are based on the conditio…
