The call for an increased role of replication,extension, and mixed‐methods study designs in organizational research

Examples from previously published work by the lead author on the role of employee health indicators on individual and organizational outcomes provide an intriguing backdrop through the use of illustration for suggesting some of the many benefits obtained by the incorporation of replication, extension, and mixed‐methods study designs in organizational research.

"Blind" testing of models for predicting the 90Sr activity concentration in river systems using post-Chernobyl monitoring data

Two different models for predicting the time-dependent mobility of (90)Sr in river systems have been evaluated using post-Chernobyl monitoring data for five large Belarusian rivers (Dnieper, Pripyat, Sozh, Besed and Iput) in the period between 1990 and 2004. The results of model predictions are shown to be in good agreement (within a factor of 5) with the measurements of (90)Sr activity concentration in river waters over a long period of time after the accident. This verifies the relatively good accuracy of the generalised input parameters of these models which were derived primarily from measurements of (90)Sr deposited after atmospheric nuclear weapons testing (NWT). For the cases studied here, the simpler AQUASCOPE model performed just as well as the more complex "Global" model which used GIS-based catchment data as an input. The reasons for this are discussed. Exponential decay equations were also curve-fitted to the data for each river to help assess the uncertainties in the predictive models.
