A brief note on Early Abbasid stucco decoration. Madinat al-Far and the first Friday Mosque of Isfahan

The aim of this paper is to demonstrate how an in-depth study of the stucco decoration could be useful in dating different phases of the Early Abbasid period in the absence of other precise archaeological evidence. Two case studies are presented: the residence of Madinat al-Far in Syria and the Early Abbasid Mosque of Iṣfahān in Iran

Visuospatial memory in dyslexia: evidence for strategic deficits.

Impairments in working memory are suggested to be one of the defining characteristics of dyslexia, and deficits in verbal recall are well documented. However, the situation regarding visuospatial memory is less clear. In a widely used measure, the Corsi blocks task, sequences of visuospatial locations can be recalled forwards, in the order presented (CF), or backwards, in reverse order (CB). Previous research has suggested that, while CF draws on spatial-sequential resources, CB may load executive and distinctly visual processes. While people with dyslexia typically show no deficit on CF, CB is rarely presented. We present three studies which indicate a consistent dyslexic deficit on CB that can be ameliorated by visual strategy instructions. Our data suggest that, without instruction, people with dyslexia are unable to adopt an effective CB strategy and this is consistent with a deficit in executive function. These results have implications for our understanding of visuospatial memory in dyslexia, and also in terms of the administration of the Corsi task to special populations

Consumers' Short- and Long-Term Response to "Mad Cow": Beef Consumption and Willingness-to-Pay for Organic Beef in Italy

This paper aims at assessing: 1) consumers' habits concerning beef consumption and their responses to the BSE both immediately and at a longer term; 2) consumers' attitudes and willingness to pay for organic beef, an obvious alternative to regular beef in terms of safety. It is based on two random telephone surveys, the first one conducted in 2001 (few months after the BSE crisis) and the second one in 2003. The analysis shows that though the effect of the BSE crisis has weakened along with time distance, it left some permanent signs in consumers' behaviour. The analysis of the effect of the time distance from the BSE crisis on consumers' attitudes towards organic beef leads to the main conclusion that the demand for organic beef reduced, but that in the meantime it became more inelastic.BSE, organic beef, willingness to pay, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Q13, Q21,

Adjusted Plus-Minus for NHL Players using Ridge Regression with Goals, Shots, Fenwick, and Corsi

Regression-based adjusted plus-minus statistics were developed in basketball and have recently come to hockey. The purpose of these statistics is to provide an estimate of each player's contribution to his team, independent of the strength of his teammates, the strength of his opponents, and other variables that are out of his control. One of the main downsides of the ordinary least squares regression models is that the estimates have large error bounds. Since certain pairs of teammates play together frequently, collinearity is present in the data and is one reason for the large errors. In hockey, the relative lack of scoring compared to basketball is another reason. To deal with these issues, we use ridge regression, a method that is commonly used in lieu of ordinary least squares regression when collinearity is present in the data. We also create models that use not only goals, but also shots, Fenwick rating (shots plus missed shots), and Corsi rating (shots, missed shots, and blocked shots). One benefit of using these statistics is that there are roughly ten times as many shots as goals, so there is much more data when using these statistics and the resulting estimates have smaller error bounds. The results of our ridge regression models are estimates of the offensive and defensive contributions of forwards and defensemen during even strength, power play, and short handed situations, in terms of goals per 60 minutes. The estimates are independent of strength of teammates, strength of opponents, and the zone in which a player's shift begins.Comment: 24 pages, 5 figures, 7 table

Italy from 1939

Over the seven decades considered in the chapter, the Italian wine industry has changed dramatically, from a dispersed production system mainly oriented to self- consumption of supply and the local market with low- value wines, to a modern industry able to satisfy an increasingly demanding domestic supply and very competitive international markets with a wide range of wines. The current situation is the result of a long process driven by many factors, acting inside and outside the sector, and mainly national and EU policies and changing domestic and international demand. The evolution of the sector happened in four different phases, marked by different drivers and characteristics. Each period is described focusing on grape growing, wine making, domestic consumption, exports and policies affecting the industry
