Task uncertainty is a key factor in teamwork research. This study analyzed the psychometric characteristics of the Spanish Model of Group Tasks Uncertainty (MITAG) in two German samples. The participants (501 team members and 104 team leaders from a German research organization) answered the MITAG together with selected items from the German Job Diagnostic Survey (JDS) and the instrument Ambiguity facets of work (Ambiguitätsfacetten der Arbeit, AfA). Confirmatory factor analysis did not reproduce the original 4-factor structure in the German sample, although the 3 newly identified factors unclarity of goals, new situations, and non-routine resemble the original factors. Results showed sound internal consistency and confirmed the convergent and discriminant validity of the new factors. The MITAG offers a concept-based short scale for researchers and practitioners.

Statistical formulations or analyses which, when applied to data and found to fit the data, are then used to verify the assumptions and parameters used in the analysis. Examples of statistical models are the linear model, binomial model, polynomial model, two-parameter model, etc.
A method of simultaneously imaging and measuring elements at the submicron level. Nuclear microscopy uses a focused high-energy ion beam of PROTONS and ALPHA PARTICLES (a nuclear microprobe) to interact with the sample. The resulting emitted radiations are analyzed by a group of techniques simultaneously: PARTICLE INDUCED X RAY EMISSION SPECTROMETRY for minor and trace element identification; Rutherford Backscattering Spectroscopy to assess sample thickness and bulk elements such as carbon, hydrogen, oxygen, and nitrogen; and Scanning Transmission Ion Microscopy to assess sample structure and density.
The prevailing temper or spirit of an individual or group in relation to the tasks or functions which are expected.
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.
