Building an Observatory of Course-of-Action in Software Engineering: towards a Link between ISO/IEC Software Engineering standards and a Reflective Practice

International audienceAs a help to compete in an evolving market, small software companies may use an observatory of their course-of-action. The course of action considers the observable aspect of the actor's activity. Its analysis provides a description of actors' activity and it can express recommendations concerning both the individual situations and the collective situation. The observatory is an articulated set of data collecting methods supported with semantic wikis and a dedicated application. A case study, based on the activity of a team of 6 young software engineers, depicts some aspects of the building and the filling of the course-of-action observatory. As primary results of this work, we may think that observing and analyzing software engineer's activity help to reveal his/her theory-in-use - what governs engineers' behavior and tends to be tacit structures - That may help engineers to establish links between "Project Processes-in-use" and a simplified Process Reference Model and contribute to reduce the fit between a project-in-action and espoused SE standards

Penetration of topical diclofenac into synovial tissue and fluid of osteoarthritic knees: a multicenter, randomized, placebo-controlled, pharmacokinetic study

Funder: GSK Consumer Healthcare S.A., Nyon, SwitzerlandBackground:: Topical diclofenac, a nonsteroidal anti-inflammatory drug, has proven efficacy and safety in the management of osteoarthritis pain. We investigated penetration of topical diclofenac into knee synovial tissue and fluid (primary objective) and evaluated relative exposure in the knee versus plasma (secondary objective). Methods:: In this phase I, double-blind, multicenter study, patients scheduled for arthroplasty for end-stage knee osteoarthritis were randomly assigned 2:1 to 4 g diclofenac diethylamine 2.32% w/w gel (92.8 mg diclofenac diethylamine, equivalent to 74.4 mg diclofenac, per application) or placebo gel, applied to the affected knee by a trained nurse/designee every 12 h for 7 days before surgery. Diclofenac concentrations were measured in synovial tissue, synovial fluid and plasma from samples obtained during surgery ⩾12 h after last application. Treatment-emergent adverse events (TEAEs) were evaluated. Results:: Evaluable synovial tissue or fluid samples were obtained from 45 (diclofenac n = 29; placebo n = 16) of 47 patients. All diclofenac-treated participants had measurable diclofenac concentrations in synovial tissue [geometric mean 1.57 (95% confidence interval (CI) 1.12, 2.20) ng/g] and fluid [geometric mean 2.27 (95% CI 1.87, 2.76) ng/ml] ⩾12 h after the last dose. Geometric mean (95% CI) ratio of diclofenac in synovial tissue:plasma was 0.32 (0.23, 0.45) and in synovial fluid:plasma was 0.46 (0.40, 0.54). TEAE rates were similar for diclofenac (55.2%) and placebo (58.8%); none were treatment related. Conclusions:: Topical diclofenac diethylamine 2.32% w/w gel penetrated into the osteoarthritic knee after repeated application and remained detectable in synovial tissue and fluid at the end of the final 12 h dosing cycle
