Strengthening Library connections in Moodle. (2017)
Presentation / Conference
Ennis, L., & Bruce, S. (2017, April). Strengthening Library connections in Moodle. Presented at MoodleMoot Ireland and UK 2017

The reading list is traditionally recognised as a collation of printed materials or a list of titles in a module descriptor, but a transition from printed collation to digital collections has been quietly taking place in libraries and universities fo...

Assessing confidence in the Chinese learner. (2004)
Presentation / Conference
Bruce, S. D. (2004, January). Assessing confidence in the Chinese learner. Paper presented at 8th CAA Conference, Loughborough: Loughborough University, Loughborough University, Loughborough, United Kingdom

This short paper firstly examines the cultural issues of confidence-based assessment by observing a Chinese learner group completing a multiple choice test in English as a Foreign Language (EFL). The results show no indication that the Chinese studen... Read More about Assessing confidence in the Chinese learner..

Accurate quantification of the proton NMR spectra of human brain metabolites. (2002)
Thesis
Bruce, S. D. Accurate quantification of the proton NMR spectra of human brain metabolites. (Thesis). Edinburgh Napier University. Retrieved from http://researchrepository.napier.ac.uk/id/eprint/5731

Magnetic Resonance Spectroscopy (MRS) can give chemically specific information about biological tissue and has become an active area of research in human metabolism in health and disease. In particular, the (1)H MKS modality is suited to studies of... Read More about Accurate quantification of the proton NMR spectra of human brain metabolites..

Choice of spectroscopic line shape model affects metabolite peak areas and area ratios. (2000)
Journal Article
Marshall, I., Bruce, S. D., Higinbotham, J., MacLullich, A., Wardlaw, J. M., Ferguson, K. J., & Seckl, J. (2000). Choice of spectroscopic line shape model affects metabolite peak areas and area ratios. Magnetic Resonance in Medicine, 44, 646-649. doi:10.1002/1522-2594(200010)44:43.0.CO;2-0

The use of Lorentzian model lineshapes leads to systematic errors in the quantification of in vivo (1)H NMR spectra. Experimental lineshapes are better modeled by the Voigt (mixed Lorentzian-Gaussian) function, leading to more accurate fits (reduced...

An analytical derivation of a popular approximation of the Voigt function for quantification of NMR spectra. (2000)
Journal Article
Bruce, S. D., Higinbotham, J., Marshall, I., & Beswick, P. H. (2000). An analytical derivation of a popular approximation of the Voigt function for quantification of NMR spectra. Journal of magnetic resonance, 142(1), 57-63. https://doi.org/10.1006/jmre.1999.1911

The approximation of the Voigt line shape by the linear summation of Lorentzian and Gaussian line shapes of equal width is well documented and has proved to be a useful function for modeling in vivo (1)H NMR spectra. We show that the error in determi... Read More about An analytical derivation of a popular approximation of the Voigt function for quantification of NMR spectra..

Use of Voigt line shape for quantification of in Vivo ‘H spectra. (1997)
Journal Article
Marshall, I., Higinbotham, J., Bruce, S. D., & Freise, A. (1997). Use of Voigt line shape for quantification of in Vivo ‘H spectra. Magnetic Resonance in Medicine, 37, 651-657. https://doi.org/10.1002/mrm.1910370504

Quantification of NMR visible metabolites by spectral modeling usually assumes a Lorentzian or Gaussian lineshape, despite the fact that experimental lineshapes are neither. To minimize systematic fitting errors, a mixed Lorentzian-Gaussian (Voig... Read More about Use of Voigt line shape for quantification of in Vivo ‘H spectra..
