Evaluating the rank-ordering method for standard maintaining
The rank-ordering method for standard-maintaining was designed for the purpose of mapping a known cut-score (e.g. a grade boundary mark) on one test to an equivalent point on the mark scale of another test, using holistic expert judgments about the quality of exemplars of candidates’ work (scripts). How should a method like this be evaluated? If the correct mapping were known, then the outcome ...
متن کاملMaintaining standards: differences between the standard deviation and standard error, and when to use each.
Many people confuse the standard deviation (SD) and the standard error of the mean (SE) and are unsure which, if either, to use in presenting data in graphical or tabular form. The SD is an index of the variability of the original data points and should be reported in all studies. The SE reflects the variability of the mean values, as if the study were repeated a large number of times. By itsel...

متن کاملMaintaining a Large Process Model Aligned with a Process Standard: An Industrial Example
An essential characteristic of mature software and system development organizations is the definition and use of explicit process models. For a number of reasons, it can be valuable to produce new process models by tailoring existing process standards (such as the V-Modell XT). Both process models and standards evolve over time in order to integrate improvements or adapt the process models to c...
متن کاملArc-Induced Long Period Gratings from Standard to Polarization-Maintaining and Photonic Crystal Fibers
In this work, we report about our recent results concerning the fabrication of Long Period Grating (LPG) sensors in several optical fibers, through the Electric Arc Discharge (EAD) technique. In particular, the following silica fibers with both different dopants and geometrical structures are considered: standard Ge-doped, photosensitive B/Ge codoped, P-doped, pure-silica core with F-doped clad...
