Minimum norm algorithms for EEG source reconstruction are studied in view of their spatial resolution, regularization, and lead-field normalization properties, and their computational efforts. Two classes of minimum norm solutions are examined: linear least squares methods and nonlinear L1-norm approaches. Two special cases of linear algorithms, the well(More)
OBJECTIVES A framework for combining bioelectric and biomagnetic data is presented. The data are transformed to signal-to-noise ratios and reconstruction algorithms utilizing a new regularization approach are introduced. METHODS Extensive simulations are carried out for 19 different EEG and MEG montages with radial and tangential test dipoles at different(More)
The present study aims to assess the current state of workplace health promotion in German banks and to draw conclusions for the organization of future workplace prevention practice. A standardized telephone interview was conducted in 198 randomly selected banks in Germany, questioning one expert on health promotion from each bank. The interviews contained(More)
The present study aims to measure the determinants of the innovative climate in German banks with a focus on workplace health management (WHM). We analyze the determinants of innovative climate with multiple regressions using a dataset based on standardized telephone interviews conducted with health promotion experts from 198 randomly selected German banks.(More)
AIMS The aim of this study is to examine the relationship between a hospital's social capital, individual decision latitude, workload and emotional exhaustion in nurses, controlling for age, sex, years of professional experience and job tenure. BACKGROUND In western countries between 15-45% of nurses working in hospitals suffer from burnout, characterised(More)
PURPOSE To investigate accident casualties' long-term subjective evaluation of treatment outcome 6 weeks and 12 months after discharge and its relation to the experienced surgeon's empathy during hospital treatment after trauma in consideration of patient-, injury-, and health-related factors. The long-term results are compared to the 6-week follow-up(More)
Current in-car navigation systems provide only a limited level of adaption to the driver and driving conditions. The driver's actual information need while interacting with the navigation interface is not taken into account. This paper aims at investigating the impact of situational features on the drivers' support need as well as proposing modes of(More)
BACKGROUND Job satisfaction in the hospital is an important predictor for many significant management ratios. Acceptance in professional life or high workload are known as important predictors for job satisfaction. The influence of social capital in hospitals on job satisfaction within the health care system, however, remains to be determined. Thus, this(More)
BACKGROUND Variable prevalence rates between 2.4 and 35% have been reported for chronic constipation across different countries worldwide, with a low 5% for Germany. OBJECTIVES AND METHODS We conducted a computer-assisted telephone interview among 15,002 representative individuals in Germany, asking about health-related problems, including constipation.(More)
Background. The prevalence of constipation in the (German) population has been shown to be 14.9% in a telephone survey, but more detailed data are required to characterize the sociographics and clinical characteristics of persons with different types of functional constipation, either constipation-predominant irritable bowel syndrome (IBS-C) or functional(More)
