TL;DR: In this paper, a PVC membrane vanillate-selective electrode has been developed for the indirect determination of vanillin, which can be extended to the determination of other aldehydes.
Abstract: A PVC membrane vanillate-selective electrode has been developed for the indirect determination of vanillin. The vanillate electrode exhibits a Nernstian response in the range 10–1–4 × 10–3M vanillate with a slope of 59 mV per concentration decade. The electrode has a reasonably wide working pH range (7.5–10.2), a fast response time (less than 30 s) and is stable for at least a month. For the determination of vanillin, vanillin was first oxidised in situ to vanillic acid, which was then determined by the vanillate-selective electrode. The results obtained with the electrode method agree well with those determined by UV spectroscopy. This methodology could be extended to the determination of other aldehydes.

TL;DR: Roomkin et al. as mentioned in this paper conducted a detailed study of managerial and professional staff in the UK, which was funded by the Economic and Social Research Council (ESRC reference F/00/23/00 98) and linked with parallel studies being undertaken in the US, Australia, New Zealand, Japan and several other European countries.
Abstract: There is an increasing realisation that managerial and professional staff play a crucial role in determining the success of the organisations which employ them, whether in the private or the public sector. Hence there is a growing concern with the quality and development of such staff. A detailed study of these important occupational groups, which was funded by the Economic and Social Research Council (ESRC reference F/00/23/00 98) was recently conducted by the authors. Although focused on Britain, the research is linked with parallel studies being undertaken in the US, Australia, New Zealand, Japan and several other European countries. The broader international study will be published within the next year as Roomkin, M. (Ed.), The Changing Character of Managerial Employment: A Comparative View Oxford, University Press, New York and Oxford. The demographic and educational trends which relate to managerial and professional employees, their careers and other aspects of the management of such human resources are discussed. The remuneration of managerial and professional staff, their unionisation and their role in the wider society are then considered.
