'Bundle of fun' or 'bunch of problems'? : Case series of khat-related deaths in the UK
(2011)Twenty million people worldwide use khat (Catha edulis). Previously confined to Eastern Africa and Arabia, consumption is spreading to other regions. Chewing khat leaves releases the stimulants cathinone and cathine. Khat ... -
Creativity and ease of ambiguous figural reversal
(2011-08)Two studies examined the relationships between self-rated and objectively measured creative ability and ease of perceiving alternative interpretations of the ambiguous Duck Rabbit figure. The studies found empirical support ... -
Judging a book by its cover : the unconscious influence of pupil size on consumer choice
(2010)Past research suggests that men perceive women with large pupils as especially attractive. We employed an innovative methodology to examine whether this effect influences consumer decision-making. A popular psychology book ... -
Analysis of the data sources, numbers and characteristics of cocaine-related DRD cases reported in Special Mortality Registries, or eventually in General Mortality Registries (GMR) when necessary : A Report for the European Monitoring Centre for Drugs and Drug Addiction
(European Monitoring Centre for Drugs & Drugs Addiction, 2012-11-15)There have been increased numbers of cocaine-related deaths reported in some European countries since the early 1990s. There are indications that cocaine deaths are more difficult to define, detect and record as such in ... -
Long-term relationships between environment and abundance in wheat of Phaeosphaeria nodorum and Mycosphaerella graminicola
(2008)Relationships between weather, agronomic factors and wheat disease abundance were examined to determine possible causes of variability on century time scales. In archived samples of wheat grain and leaves obtained from the ... -
Quantitative resistance increases the durability of qualitative resistance to Leptosphaeria maculans in Brassica napus
(2010)It has frequently been hypothesized that quantitative resistance increases the durability of qualitative (R-gene mediated) resistance but supporting experimental evidence is rare. To test this hypothesis, near-isogenic ... -
Investment Volatility : A critique of standard beta estimation and a simple way forward
(2008)Beta is a widely used quantity in investment analysis. We review the common interpretations that are applied to beta in finance and show that the standard method of estimation – least squares regression – is inconsistent ... -
Least Squares Percentage Regression
(2008-11)In prediction, the percentage error is often felt to be more meaningful than the absolute error. We therefore extend the method of least squares to deal with percentage errors, for both simple and multiple regression. Exact ... -
A different approach to university rankings
(2012-01)Educationalists are well able to find fault with rankings on numerous grounds and may reject them outright. However, given that they are here to stay, we could also try to improve them wherever possible. All currently ... -
The Mediterranean Diet : Health and Science
(Wiley-Blackwell, 2011)Recent large–scale epidemiological studies have confirmed the pre–eminence of the Mediterranean diet for reducing the risk of primary and secondary heart disease and cancer. There is also increasingly convincing evidence ... -
Effect of electric current pulse treatment on the corrosion rate and strength of specimens made of 45 steel
(2010)The paper presents results of static tensile tests of specimens made of 45 steel after holding them for 100 h in a corrosive medium. It has been shown that due to the pretreatment of specimens with electric current pulse ... -
Analysis of porosity in NiTi SMA's changed by secondary pulse electric current treatment by means of ultra small angle scattering and micro-computed tomography
(2010)Porous NiTi samples were produced by two different techniques, Mechanical Alloying & Hot Pressing (MA&HP) and Reaction Synthesis (RS), followed by secondary Pulse Electric Current (PEC) treatment. The samples were analyzed ... -
Redistribution of residual welding stresses in pulsed electromagnetic treatment
(2011)Experimental results demonstrate that in an AMg6 alloy specimen after pulsed electromagnetic treatment, a significant decrease and redistribution of residual welding stresses are observed. Numerical simulation corroborates ... -

The Bard returns to Shoreditch : Shakespearean Productions at the Britannia Theatre
(2008-01)Histories of nineteenth-century Shakespearean performances tend to concentrate on those produced at West End theatres. The minor theatres, attracting lower-class audiences, are largely ignored. This essay documents and ... -
Pugilists and Greasepaint : Theatrical Encounters with a Bare-knuckle Fighter and Pantomime Clown
(2009-12)One of the advantages of the key-wording of entries in the new British Library Manuscript Catalogue is that it facilitates the identification of plays dealing with particular issues or events. It thus allows us to build ... -
Range and severity of a plant disease increased by global warming
(2008-06-05)Climate change affects plants in natural and agricultural ecosystems throughout the world but little work has been done on the effects of climate change on plant disease epidemics. To illustrate such effects, a weather-based ... -
Quantitative particle size, microtextural and outline shape analyses of glacigenic sediment reworked by paraglacial debris flows
(2009)Particle size analysis and scanning electron microscopy have been used with some success to differentiate sediments sampled from varying geomorphological environments. In the paraglacial environment, however, discrimination ...
