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 ...

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 ...

We propose a broad measure of liquidity for the overall financial market by exploiting its connection with the amount of arbitrage capital in the market and the potential impact on price deviations in US Treasurys. When arbitrage capital is abundant, we expect the arbitrage forces to smooth out the Treasury yield curve and keep the dispersion low. During market crises, the shortage of arbitrage...

The aim of this study was to evaluate the knowledge and practices of minimal intervention dentistry (MID) in the teaching hospitals of Lahore. The target population for this cross-sectional study consisted of fresh graduates, house surgeons and demonstrators of Restorative Dentistry in the dental schools of Lahore. The questionnaire was prepared to assess the teaching and concepts of minimal in...

Our objective in this article is to study analytically the effect of borrowing constraints on asset returns in an economy where agents are heterogenous with respect to their risk aversion. We use asymptotic analysis to characterize the equilibrium in a general equilibrium exchange economy with an arbitrary number of agents who differ in their risk aversion and face limits on borrowing. We find ...

Objective: To study the prevalence of Post Partum Depression (PPD)in Indian women and to evaluate the risk factors for the development of PPD. Materials And Methods: This cross-sectional study was done among 278 novel mothers (post delivery 10 days to 3 months) attending post partum clinics of K.P.C.Medical College & Hospital. Socio-economic factors and detailed obstetric variables were assesse...

PURPOSE To investigate the impact of selected corporate environment factors, health risks, and medical conditions on job performance using a self-reported measure of presenteeism. DESIGN A cross-sectional survey utilizing health risk appraisal (HRA) data merging presenteeism with corporate environment factors, health risks, and medical conditions. SETTING Approximately 8000 employees across...

The cross-section of realized return volatilities of US equities between 1965-2004 is well described by a linear factor structure. We show that the identified factor structure has important cross-sectional pricing implications for variance swap contracts. The principal volatility factor accounts for almost 40% of the cross-sectional variation in realized stock volatilities and earns a significa...

This paper provides empirical evidence that firm size, liquidity, and Value-at-Risk (VaR) explain the cross-sectional variation in expected returns, while market beta and total volatility have almost no power to capture the cross-section of expected returns at the firm level. The strong positive relation between average returns and VaR turns out to be robust across different investment horizons...

In this paper we develop a continuous-time general equilibrium model in a representative exchange economy with incomplete information. We show, in a multiple assets setting, that state uncertainty risk is priced and commands additional (state-dependent) premium. It is affected by both the investor’s estimate of the state of the economy, as well as the uncertainty about her estimation. Moreover,...
