We consider estimation in generalized linear mixed models (GLMM) for longitudinal data with informative dropouts. At the time a unit drops out, time-varying covariates are often unobserved in addition to the missing outcome. However, existing informative dropout models typically require...

A flexible semiparametric class of models is introduced that offers an alternative to classical regression models for count data as the Poisson and Negative Binomial model, as well as to more general models accounting for excess zeros that are also based on fixed distributional assumptions. The...

The use of a shroud is known to improve performance. In this work, the flow physics and performance of shrouded turbines is assessed by solving the Reynolds Averaged Navier–Stokes equations supplemented with a transition model. Shroud geometries are evaluated for their augmentation of mass...

The paper presents part of the overall United Nations Environment Programme Mediterranean work on the Implications of Future Climatic Changes for the Mediterranean Coastal Region. Most of this was published in Climatic Changes and the Mediterranean; Environmental and societal impacts of climatic...

Tourism is very sensitive to events that could trouble what is normal from a natural, economic, political and social point of view in the tourists’ countries, in the countries they visit, and in the countries of transit. Consequently, the economic crises, the military, social or ethnical...

ENGLISH ABSTRACT: Experimental research in psychology and economics indicates that depression causes heightened risk aversion. Previous research has documented robust links between seasonal variation in length of day, seasonal depression (known as seasonal affective disorder, or SAD), risk...
