The recent special issue of JET showed narratives schools shifting to emergency online teaching centred on coping strategies and struggling with tools. Even where the sense helped overcome long-standing resistance pedagogical change, emphasis remained ‘coping’ exposing unmet need for teachers be able adapt from traditional classroom pedagogies. being unprepared was echoed in ‘struggling’ Ontari...

Almost all teachers are required to submit final grades for their students. In this note we discuss the uncertainty in those grades with an emphasis on grades in physics courses. We will estimate that the statistical uncertainty in final grades is at least 4% out of 100%, and is probably significantly higher than this. The implications of this result on things like calculating Grade Point Avera...

This paper makes a case, to system developers, for inter-disciplinary working and the involvement of sociologists in the systems design process. Our argument is based on the fact that effective systems must take account of the social context in which these systems are situated. The paper is based on our experiences of working with sociologists in a study of air traffic control automation. We de...

We investigated the ability of humans to optimize face recognition performance through rapid learning of individual relevant features. We created artificial faces with discriminating visual information heavily concentrated in single features (nose, eyes, chin or mouth). In each of 2500 learning blocks a feature was randomly selected and retained over the course of four trials, during which obse...

While the phylum Apicomplexa includes "only" several thousand described species of obligatory parasites of animals, it may in fact be the most specious group of parasitic protists with over a million species 1. The best known representatives are Plasmodium spp., Toxoplasma gondii and Cryptosporidium spp., which belong to the most important and widespread human parasites exacting an enormous dis...

We have found an extremely large ribonuclease P (RNase P) RNA (RPR1) in the human pathogen Candida glabrata and verified that this molecule is expressed and present in the active enzyme complex of this hemiascomycete yeast. A structural alignment of the C. glabrata sequence with 36 other hemiascomycete RNase P RNAs (abbreviated as P RNAs) allows us to characterize the types of insertions. In ad...
