Die beleweniswêreld van onafhanklike sakemanne
A. C. Gmeiner,M. Poggenpoel
South African Journal of Industrial Psychology , 1994, DOI: 10.4102/sajip.v20i3.576
Abstract: The inner experiences of the independant businessman. In this study the inner experiences of the independant businessman is described and analised. An exploratory, descriptive, qualitative and contextual design was used. Phenomenological semistructured interviews were conducted with a purposively selected sample of fifteen independant businessmen. A literature control was conducted as a reliability measure. The insight gained from this research contributes to a better understanding of the total life experiences of the independant businessman. The results can be operationalised in further research and practice with a view to promoting the mental health of the independant businessman. Opsomming In hierdie studie word die beleweniswereld van die onafhanklike sakeman verken en beskryf. 'n Verkennende, beskrywende, kwalitatiewe en kontekstuele ontwerp is gebruik. Fenomenologiese semi-gestruktureerde onderhoude is gevoer met 'n doelgerigte geselekteerde steekproef van vyftien onafhanklike sakemanne. 'n Literatuurkontrolc is uitgevoer as betroubaarhcidsmaatreel. Die insig verkry uit hierdie navorsing dra by tot meer begrip van die totale beleweniswereld van die onafhanklike sakeman. Die resultate kan operasionaliseer word in verdere navorsing sowel as in die praktyk ten einde die geestesgesondheid van die onafhanklike sakeman te bevorder.
Precipitation observation using microwave backhaul links in the alpine and pre-alpine region of Southern Germany

Hydrology and Earth System Sciences Discussions , 2012, DOI: 10.5194/hessd-9-741-2012
Abstract: Measuring rain rates over complex terrain is afflicted with large uncertainties because rain gauges are influenced by orography and weather radars are mostly not able to look into mountain valleys. We apply a new method to estimate near surface rain rates exploiting attenuation data from commercial microwave links in the alpine region of Southern Germany. Received signal level (RSL) data is recorded minutely with small data loggers at the towers and then sent to a database server via GSM. Due to the large RSL fluctuations in periods without rain, the determination of attenuation caused by precipitation is not straightforward. To be able to continuously process the RSL data from July 2010 to October 2010, we introduce a new method to detect wet and dry periods using spectral time series analysis. We show the performance and limitations of the method and analyse the derived rain rates compared to rain gauge and weather radar measurements. The resulting correlations differ for different links and reach values of R2 = 0.80 for the link-gauge comparison and R2 = 0.84 for the link-radar comparison.
'n Model vir die bevordering van die geestesgesondheid van onafhanklike sakemanne
A. Gmeiner,M. Poggenpoel
South African Journal of Industrial Psychology , 1998, DOI: 10.4102/sajip.v24i1.641
Abstract: A model for the promotion of mental health of independent businessmen. In this article the research is described that had as goal the generation of a practice-orientated model for the promotion of the mental health of independent businessmen. The research design utilised a qualitative, theory-generating design, based on the model of Dickoff, James and Wiedenbach (1968). Reliability and validity of this research was ensured by utilizing the measures of reliability and validity of Woods and Catanzaro (1988). The model was described in terms of structure and process and, lastly, evaluated according to criteria set by Chinn and Jacobs (1987). Opsomming In hierdie artikel word die navorsing beskryf wat ten doel gehad het om die genereringvan 'n praktykgcrigte model vir die bevordering van die gccstesgesondheid van onafhanklike sakemanne. Die navorsing het behels 'n kwalitatiewe, teorie-genererende ontwerp gebasecr op die model van Dickoff, James en Wiedenbach (1968). Geldigheids- en betroubaarheidsmaatreels volgens Woods en Catanzaro (1988) is toegepas om betroubaarheid en geldigheid van die navorsing te verseker. Die model is beskryf in terme van struktuur en proses en is ten slotte geevalueer volgens kriteria gestel deur Chinn en Jacobs (1987).
Precipitation observation using microwave backhaul links in the alpine and pre-alpine region of Southern Germany

Abstract: Measuring rain rates over complex terrain is afflicted with large uncertainties, because rain gauges are influenced by orography and weather radars are mostly not able to look into mountain valleys. We apply a new method to estimate near surface rain rates exploiting attenuation data from commercial microwave links in the alpine region of Southern Germany. Received signal level (RSL) data are recorded minutely with small data loggers at the towers and then sent to a database server via GSM (Global System for Mobile Communications). Due to the large RSL fluctuations in periods without rain, the determination of attenuation caused by precipitation is not straightforward. To be able to continuously process the RSL data from July 2010 to October 2010, we introduce a new method to detect wet and dry periods using spectral time series analysis. Its performance and limitations are presented, showing that the mean detection error rates of wet and dry periods can be reduced to 10% for all five links. After, the wet/dry classification rain rates are derived from the RSL and compared to rain gauge and weather radar measurements. The resulting correlations differ for different links and reach values of R2 = 0.81 for the link-gauge comparison and R2 = 0.85 for the link-radar comparison.
Active-State Models of Ternary GPCR Complexes: Determinants of Selective Receptor-G-Protein Coupling
Ralf C. Kling, Harald Lanig, Timothy Clark, Peter Gmeiner
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0067244
Abstract: Based on the recently described crystal structure of the β2 adrenergic receptor - Gs-protein complex, we report the first molecular-dynamics simulations of ternary GPCR complexes designed to identify the selectivity determinants for receptor-G-protein binding. Long-term molecular dynamics simulations of agonist-bound β2AR-Gαs and D2R-Gαi complexes embedded in a hydrated bilayer environment and computational alanine-scanning mutagenesis identified distinct residues of the N-terminal region of intracellular loop 3 to be crucial for coupling selectivity. Within the G-protein, specific amino acids of the α5-helix, the C-terminus of the Gα-subunit and the regions around αN-β1 and α4-β6 were found to determine receptor recognition. Knowledge of these determinants of receptor-G-protein binding selectivity is essential for designing drugs that target specific receptor/G-protein combinations.
