This meta-analysis seeks to critically examine the qualitative research being published in influential journals in the field of international and comparative education in order to determine whether qualitative research has remained true to the constructivist paradigm and its theoretical and philosophical underpinnings. Decades after the heated paradigmatic debates within the field of education in the 1980's, we seek to examine whether predictions that the constructivist paradigm would be pushed out by the call for post-positivist, quantifiable, data-driven research have come to fruition. Based on a review of all qualitative research published in the past three volumes of five influential journals in the field, we conclude that while qualitative articles are represented in approximately equal numbers as quantitative articles, there are key elements of the constructivist paradigm that are largely absent from these qualitative articles. In particular, our conclusion attempts to address the concern that qualitative researchers are failing to address the issue of researcher positionality in their qualitative work.

Objective Four sets of eight audible alarms matching the functions specified in IEC 60601-1-8 were designed using known principles from auditory cognition with the intention that they would be more recognizable and localizable than those currently specified in the standard. Background The audible alarms associated with IEC 60601-1-8, a global medical device standard, are known to be difficult to learn and retain, and there have been many calls to update them. There are known principles of design and cognition that might form the basis of more readily recognizable alarms. There is also scope for improvement in the localizability of the existing alarms. Method Four alternative sets of alarms matched to the functions specified in IEC 60601-1-8 were tested for recognizability and localizability and compared with the alarms currently specified in the standard. Results With a single exception, all prototype sets of alarms outperformed the current IEC set on both recognizability and localizability. Within the prototype sets, auditory icons were the most easily recognized, but the other sets, using word rhythms and simple acoustic metaphors, were also more easily recognized than the current alarms. With the exception of one set, all prototype sets were also easier to localize. Conclusion Known auditory cognition and perception principles were successfully applied to an existing audible alarm problem. Application This work constitutes the first (benchmarking) phase of replacing the alarms currently specified in the standard. The design principles used for each set demonstrate the relative ease with which different alarm types can be recognized and localized.
