Novel opto-electronic and plastic fibre sensors
Published 1998“…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”

Imagined cities (Voicescapes)
Published 2015“…RESEARCH QUESTIONS While the field of vocal studies has progressively emphasised the interdisciplinary potential of vocal performance (Novak, 2015; Thomaidis and Macpherson, 2015), the idea of durational/installational live singing is still a little explored subject. • How may live singing be used to create a durational, post-dramatic exhibit? …”

Rethinking learning outcomes : review of Trevor Hussey & Patrick Smith (2003) ‘The Uses of Learning Outcomes’, Teaching in Higher Education, Vol. 8. No 3, pp. 357-368
Published 2005“…Picking up the baton from their earlier article The Trouble With Learning Outcomes, in which they detailed a persuasively cautionary account of the dangers inherent in using learning outcomes as tools of audit rather than of education, Hussey and Smith (2002) return on a mission: ‘to develop an account of learning outcomes… that is more realistic and conducive to educational purposes’ (p. 232). …”

Pro-social attitudes towards ethno-religious out-groups during the COVID-19 pandemic: a survey experiment in five countries
Published 2024“…This article examines pro-social attitudes among 7000 residents in England, Ireland, Germany, Serbia, and Sweden by showing a fictitious scenario of an older neighbour who needs his groceries to be picked up from a nearby supermarket. The online survey experiment follows a 3 × 2 × 2 factorial design varying the ethno-religious origin of neighbours signalled by the name (Alexander vs Mohammed), the length of their residence (<1 year, 10 years, entire life), and if groceries, or groceries and beer need to be collected. …”
