16. Calling for change : the effectiveness of helpline counselling and spontaneous change in problematic alcohol use
Abstract : Population studies have estimated the remission rate from alcohol use disorders as well as the life course trajectory of alcohol consumption. However, less is known about the spontaneous change to low-risk use in populations of hazardous and heavy drinkers. READ MORE

17. Uncertainties in tropical precipitation and radiative feedbacks under climate change
Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

18. Microbial temperature dependences in soil: The belowground feedback to climate change
Abstract : Since the Industrial Revolution, human activities have elevated atmospheric CO² concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. READ MORE

19. Shallow Brooks and Rivers Wide : A Study of Lexical and Semantic Change in English Nouns Denoting Watercourse
Abstract : This study is intended to provide new insight into the change and stability of lexical fields by means of a new theoretical model for the identification, description and interpretation of the mechanisms of lexical and semantic change.The first part of the study is a detailed investigation of the origin and innovation of the nouns within the lexical field ‘watercourse’ in order to be able to account for the patterns of creation, especially in relation to the current status of the nouns.

20. Uncertainty quantification for high frequency waves
Abstract : We consider high frequency waves satisfying the scalar wave equation with highly oscillatory initial data represented by a short wavelength ε. The speed of propagation of the medium as well as the phase and amplitude of the initial data is assumed to be uncertain, described by a finite number of independent random variables with known probability distributions.
