Implementing a compliance manager (1998)
Armitage, S., Stevens, R., Finkelstein, A.
Many companies claim to adhere to standards for software project development. This is often used as a marketing tool when eliciting business. But how does the customer or project manager know that...
Standards compliant software development (1997)
Emmerich, W., Finkelstein, A., Montangero, C., Stevens, R.
Software engineering standards determine practices that `compliant' software processes shall follow. Standards generally define practices in terms of constraints that must hold for documents. The...

The effect of 6-mercaptopurine on natural killer-cell activities in Crohn's disease (1985)
Korelitz, B., Oliver, M., Brogan, M., Hiserodt, J. C., Stevens, R., Targan, S.
Crohn's disease patients on long-term 6-mercaptopurine therapy (more than 4 months) were evaluated for activity of peripheral blood natural killer cells. Natural killer-cell cytolytic activity...
Search for heavy neutral leptons in e+e- annihilations at 29 GeV (1984)
Errede, D., Akerlof, Carl W., Chapman, Jay W., Harnew, N., Kesten, P., Kooijman, S., ...
A search was made in 29 GeV e+e- annihilations for heavy, neutral leptons decaying to e+/-X[mnplus]([nu]), where X is a muon or charged meson. Six events with isolated e+/-X[mnplus] pairs were found...
Charm quark production and fragmentation in e+e- annihilation at 29 GeV (1984)
Derrick, M., Fernandez, E., Fries, R., Hyman, L., Kooijman, P., Loos, J. S., ...
The electroweak production asymmetry and the decay fragmentation function for have been measured at using charged D* production over the full kinematic range. The data were taken at PEP using the...
Gibson, M., Moody, D., Stevens, R.
Measurements are reported of the low temperature (1-4 °K) specific heats and susceptibilities of PdPt alloys. The analysis of the results in terms of a uniform and localised enhancement models is...
