BACKGROUND Many classification systems for grading pressure ulcers are discussed in the literature. Correct identification and classification of a pressure ulcer is important for accurate reporting of the magnitude of the problem, and for timely prevention. The reliability of pressure ulcer classification systems has rarely been tested. AIMS AND OBJECTIVES The purpose of this paper is to exam...

Job Loss Fears and (Extremist) Party Identification: First Evidence from Panel Data There is a large body of literature analyzing the relationship between objective economic conditions and voting behavior, but there is very little evidence of how perceived economic insecurity impacts on political preferences. Using seventeen years of household panel data from the German Socio-Economic Panel, we...

Smoking Persistence Across Countries: An Analysis Using Semi-Parametric Dynamic Panel Data Models with Selectivity We study smoking persistence in ten countries using data from the European Community Household Panel. Such persistence may be due to true state dependence but may also reflect individual unobserved heterogeneity. We distinguish between the two by using semiparametric dynamic panel ...

Self-Employment: A Way to End Unemployment? Empirical Evidence from German Pseudo-Panel Data This paper contributes to the policy-relevant question whether self-employment is a way out of (long-term) unemployment. We estimate the relationship between the entry rate into selfemployment and previous (long-term) unemployment on the basis of pseudo-panel data for Germany in the period 1996-2002. Th...

Real Wage Cyclicality in Germany and the UK: New Results Using Panel Data This paper compares the cyclical behaviour of male real wages in Germany and the UK using the German Socio-Economic Panel 1984-2002 and the British Household Panel Survey 1991-2004. We distinguish between job stayers (remaining in the same job), and withinand between-company job movers. Stayers are the large majority in b...

Subjective Well-Being and the Family: Results from an Ordered Probit Model with Multiple Random Effects The previous literature on the determinants of individual well-being has failed to fully account for the interdependencies in well-being at the family level. This paper develops an ordered probit model with multiple random effects that allows to identify the intrafamily correlation in well-be...

In the first half of the paper I study spurious regressions in panel data. Asymptotic properties of the least-squares dummy variable (LSDV) estimator and other conventional statistics are examined. The asymptotics of LSDV estimator are different from those of the spurious regression in the pure time-series. This has an important consequence for residual-based cointegration tests in panel data, ...

NGS: next-generation sequencing STAMP: Stanford targeted next-generation sequencing panel INTRODUCTION The molecular classification of melanomas, which can have diverse clinical and histopathologic features, is defined by the acquisition of somatic mutations. Mutations such as BRAF V600E result in constitutive activation of critical signaling pathways that promote formation of melanocytic nevi....
