Actinic keratoses (AKs) are common cutaneous lesions that develop as a result of ultraviolet (UV) radiation damage.1 Risk factors associated with AKs include advanced age, male gender, high degree of sun and/or artificial UV exposure, and fair skin.2 Epidemiological studies within Europe are limited and have provided highly variable estimates of AK point prevalence (1--38%).2--6 Cumulative sun ...

Despite the importance of behaviour management training, many student teachers report being inadequately trained in this area. The aim of this study was to identify the strategies, confidence and reported levels of success in regards to various behaviour management strategies, across 509 first, second, third and fourth year student teachers training to be primary teachers. The most significant ...

In this article, we show how to analyze analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio constraints. The exact local comparative statics and approximate but analytical expression for the portfolio ...

Background: The growth and success of any organization usually depends on its employees. Turnover in health care institutions has significant challenge on customer service levels, company profits, and cause training and expatriation losses cost. In light of current concerns over nursing shortages, nurse’s turnover intent is a topic of great importance. The healthcare community needs to be conce...

When a risk factor has small covariance with asset returns, risk premia in the linear asset pricing models are no longer identified. Weak factors, similar to weak instruments, make the usual estimation techniques unreliable. When included in the model, they generate spuriously high significance levels of their own risk premia estimates, overall measures of fit and may crowd out the impact of th...

Currently in healthcare organizations paper-based patient record management faces many challenges. Most countries are promoting the full implementation of electronic medical records in every hospital. Medical environments change frequently and dramatically, which makes full acceptance of electronic medical records (EMR) by physicians an important issue. This empirical study combines the theory ...

Survivability engineering is critical for minimizing the impact of disturbances to the operation of space systems. To improve the evaluation of survivability during conceptual design, metrics are proposed for the assessment of survivability as a dynamic, continuous, and path-dependent system property. Two of these metrics, time-weighted average utility loss and threshold availability, are then ...

Design: The Safer California Universities study involved 14 large public universities, half of which were assigned randomly to the Safer intervention condition after baseline data collection in 2003. Environmental interventions took place in 2005 and 2006 after 1 year of planning with seven Safer intervention universities. Random cross-sectional samples of undergraduates completed online survey...

Recently, there has been considerable interest among accounting researchers in the relation between asymmetric information and cost of capital. A number of empirical studies document associations between proxies for asymmetric information such as earnings quality and risk premiums. However, the theoretical foundation for these studies has yet to be fully established. In this study, we consider ...
