A Descriptive Analysis on the Implementation of Balanced Scorecards in German-Speaking Countries

Abstract: This paper provides systematic research-based evidence on the usage of the BSC concept in German-speaking countries. We develop three primary types of BSC usage reflecting the successive phases in the evolution of the BSC concept and of its implementation in practice. This typology ranges from the BSC's origin as a multidimensional framework for strategic performance measurement that combines financial and non-financial measures to its advanced usage as an integrated strategic management system that describes strategy by a cause-and-effect logic and that is linked to the reward system. We use this theoretical framework to analyze the spread, implementation and benefits of the different types of Balanced Scorecards. Moreover, the impact of size and industry on BSC usage is analyzed. Our sample consists of a clearly defined segment of the most important publicly traded firms in Germany, Austria and Switzerland and we achieved an overall response rate of 87%.

Isoprene and acetone concentration profiles during exercise on an ergometer

Abstract: A real-time recording setup combining exhaled breath volatile organic compound (VOC) measurements by proton transfer reaction-mass spectrometry (PTR-MS) with hemodynamic and respiratory data is presented. Continuous automatic sampling of exhaled breath is implemented on the basis of measured respiratory flow: a flow-controlled shutter mechanism guarantees that only end-tidal exhalation segments are drawn into the mass spectrometer for analysis. Exhaled breath concentration profiles of two prototypic compounds, isoprene and acetone, during several exercise regimes were acquired, reaffirming and complementing earlier experimental findings regarding the dynamic response of these compounds reported by Senthilmohan et al (2000 Redox Rep. 5 151-3) and Karl et al (2001 J. Appl. Physiol. 91 762-70). While isoprene tends to react very sensitively to changes in pulmonary ventilation and perfusion due to its lipophilic behavior and low Henry constant, hydrophilic acetone shows a rather stable behavior. Characteristic (median) values for breath isoprene concentration and molar flow, i.e., the amount of isoprene exhaled per minute are 100 ppb and 29 nmol min(-1), respectively, with some intra-individual day-to-day variation. At the onset of exercise breath isoprene concentration increases drastically, usually by a factor of ∼3-4 within about 1 min. Due to a simultaneous increase in ventilation, the associated rise in molar flow is even more pronounced, leading to a ratio between peak molar flow and molar flow at rest of ∼11. Our setup holds great potential in capturing continuous dynamics of non-polar, low-soluble VOCs over a wide measurement range with simultaneous appraisal of decisive physiological factors affecting exhalation kinetics. In particular, data appear to favor the hypothesis that short-term effects visible in breath isoprene levels are mainly caused by changes in pulmonary gas exchange patterns rather than fluctuations in endogenous synthesis.
