This research draws on team adaptation theory to study how agile information systems development (ISD) teams respond to non-routine events in their work environment. Based on our findings from a qualitative case study of three ISD teams, we identified non-routine events that could be distinguished according to the three categories task volatility,(More)
The standing posture of 17 young men and women were studied using Barycentremeter measurements and full spine radiograph with a single referential system. These procedures provide in vivo measurements of the weight and center of weight supported by each vertebra and the coxofemoral joints. The relationship between the vertebra, the sacrum or the coxofemoral(More)
BACKGROUND Diseases of the venous system are widespread disorders sometimes associated with modern civilisation and are among the major concerns of social and occupational medicine. This study was carried out to compare the efficacy (oedema reduction) and safety of compression stockings class II and dried horse chestnut seed extract (HCSE, 50 mg aescin,(More)
BACKGROUND Complications of idiopathic intracranial hypertension (IIH) are usually caused by elevated intracranial pressure (ICP). In a similar way as in the optic nerve, elevated ICP could also compromise the olfactory nerve system. On the other side, there is growing evidence that an extensive lymphatic network system around the olfactory nerves could be(More)
SAP AG has taught more than 4,000 developers the Agile Software Engineering methodology since 2010. As such, the company offers a unique setting to study its impact on developers' work. In this paper, we discuss how developers perceive the impact of pair programming and test automation on software quality, delivered feature scope, and various team work(More)

While agile development methods have enjoyed widespread adoption, literature has lagged behind in the development of theory to explain its impact on team performance. In this paper, we develop a theoretical model to explain the impact of agile software development on the performance of information systems development (ISD) teams. We first propose a new(More)
OBJECTIVE To evaluate 3D spectral domain optical coherence tomography (SDOCT) volume scans as a tool for quantification of optic nerve head (ONH) volume as a potential marker for treatment effectiveness and disease progression in idiopathic intracranial hypertension (IIH). DESIGN AND PATIENTS Cross-sectional pilot trial comparing 19 IIH patients and(More)
