Improving the psychological evaluation of exercise referral: psychometric properties of the Exercise Referral Quality of Life Scale

There is a growing need to assess the psychological outcomes of exercise referral and the National Institute of Health and Care Excellence has called for the routine assessment of life-quality. However, a quality of life scale specific to the requirements of exercise referral is currently unavailable. Therefore, the aim of this study was to produce a quality of life measure for this purpose. The Exercise Referral Quality of Life Scale is a 22-item measure comprising three domains: mental and physical health, injury pain and illness and physical activity facilitators. Exploratory factor analysis determined the initial factor structure and was subsequently confirmed by confirmatory factor analysis. Additional scale properties were also assessed. The scale contributes to the global need for improved consistent psychological outcome assessment of exercise referral

Restricting paracetamol in the United Kingdom to reduce poisoning: a systematic review

Background Paracetamol poisoning is implicated in about 150-200 poisoning deaths per year in England and Wales. We review previous studies assessing the effectiveness of regulations introduced in 1998 to restrict sales of paracetamol and reduce paracetamol poisoning. Methods We searched the following electronic databases: MEDLINE, EMBASE, CINHAL, HIMIC, COCH, APC, CENTRAL and DARE. English language publications between 1998 and 2003 were included. Studies were included if they took place in the United Kingdom and assessed changes in any aspect of paracetamol poisoning following the introduction of the 1998 regulations. Results Twelve studies were identified, which examined several different outcomes. Three studies examined admissions to liver transplant units; all reported reductions. Eight studies evaluated severity of paracetamol poisoning; three reported reductions but five did not. Five out of six studies reported reductions in hospital admissions. One study reported reduced mortality in England and Wales after 1 year while another found no difference in Scotland 2 years after the regulations were introduced. Two studies observed a significant reduction in over-the-counter sales. Studies suffered from several limitations including short follow-up periods, no case definition for paracetamol poisoning and lack of comparison groups. Conclusions The limitations of these studies makes it difficult to draw firm conclusions. They do, however, suggest that the 1998 regulations may have been associated with reduced admissions to liver units and liver transplants, reduced hospital attendance due to paracetamol poisoning and reduced sales of paracetamol. Further research is needed to fully evaluate the impact of the 1998 regulations. In the future, formal evaluation of the impact of similar interventions should be an integral part of policy formation

Orientifolds and twisted boundary conditions

It is argued that the T-dual of a crosscap is a combination of an O+ and an O- orientifold plane. Various theories with crosscaps and D-branes are interpreted as gauge-theories on tori obeying twisted boundary conditions. Their duals live on orientifolds where the various orientifold planes are of different types. We derive how to read off the holonomies from the positions of D-branes in the orientifold background. As an application we reconstruct some results from a paper by Borel, Friedman and Morgan for gauge theories with classical groups, compactified on a 2-- or 3--torus with twisted boundary conditions.Comment: 23 pages, LaTeX, 2 eps figures; minor corrections, references adde

On the bounded generation of arithmetic SL2{\rm SL}_2

Let $K$ be a number field and ${\mathcal O}$ be the ring of $S$-integers in $K$. Morgan, Rapinchuck, and Sury have proved that if the group of units ${\mathcal O}^{\times}$ is infinite, then every matrix in ${\rm SL}_2({\mathcal O})$ is a product of at most $9$ elementary matrices. We prove that under the additional hypothesis that $K$ has at least one real embedding or $S$ contains a finite place we can get a product of at most $8$ elementary matrices. If we assume a suitable Generalized Riemann Hypothesis, then every matrix in ${\rm SL}_2({\mathcal O})$ is the product of at most $5$ elementary matrices if $K$ has at least one real embedding, the product of at most $6$ elementary matrices if $S$ contains a finite place, and the product of at most $7$ elementary matrices in general

Equity valuation : Under Armour

The present dissertation aims to value Under Armour, an American sportswear company. Since Valuation is not an exact science, during the literature review will be presented several valuation methods. Most of the authors mention DCF Valuation as one of the best but it seems impossible for them to reach a consensus about which one is in fact the best. In order to get Under Armour’s target price, a DCF valuation will be made and accompanied by a Relative Valuation that, when it is properly used, it can perform the perfect complement. In the end, a comparison between the dissertation’s result and JP Morgan report will be made. In January 2016, JP Morgan was predicting a target price of $90 per share.A presente dissertação tem como objetivo avaliar a Under Armour, uma empresa americana de têxtil desportivo. Uma vez que uma avaliação não é uma ciência exata, durante a revisão de literatura serão apresentados alguns métodos de avaliação. Para muitos autores uma avaliação feita através do DCF é considerada como uma das melhores, mas parece impossível para os mesmos chegar a um consenso sobre que é realmente o melhor método. Para chegar ao preço final da Under Armour, uma avaliação usando o DCF irá ser feita e acompanhada por uma avaliação por múltiplos que quando usada adequadamente, pode desempenhar o papel de perfeito complemento para a primeira. No final irá ser realizado uma comparação entre o resultado obtido na dissertação e o relatório feito pela JP Morgan. Em Janeiro de 2016 a JP Morgan estava a prever um preço final de$90 por ação
