Effects of interactions between leaching, frost action and abrasion on the surface deterioration of concrete

Surface deterioration of concrete occurs at the waterline of many hydraulic structures in contact with soft water in cold regions. Progressive disintegration of the surface leads to exposure of the coarse aggregate and ultimately of the reinforcing steel. Mechanical, physical and chemical processes could cause deterioration of concrete at the waterline. The objective of this study was to investiga

Separating semantic and perceptual factors in the picture superiority effect

Memory for pictures is known to surpass memory for corresponding concrete words, an effect often attributed to the more distinctive perceptual form of pictures. A consequence of this view is that picture superiority would not survive a transformation in which only semantic, not perceptual, features were preserved from study to test, such as studying a picture of a horse and recognising the word "h

How is capability assessment related to risk assessment? Evaluating existing research and current application from a design science perspective

Several countries use capability assessments as a part of their efforts to manage risk. However, it is unclear how such assessments are connected to other risk management activities, e.g. risk assessment. Therefore, the aim of the present paper is to present a study of how capability assessment is related to risk assessment. Capability assessment methods were identified through a scoping study and

Income tax progressivity and war inflation during the two World Wars

Top marginal rates in income taxes increased significantly during the two World Wars in most Western countries, which points towards increases in their progressivity. We argue, however, that this war-related effect is less clear-cut than previously thought: wartime inflation could have exerted a counteracting impact by pushing citizens into higher tax brackets, including new individuals from the b
