Accommodating practices during episodes of disillusionment with mobile IT

This study investigates how tablet users react when technology falls short of their expectations. We deploy a data/frame model to study this process and investigate resistance-related reactions and the deployment of accommodating practices at the individual level. Analyzing user blogs that provide narratives on user interaction with tablets, we identify triggers of episodes of disillusionment and illustrate five sensemaking paths that users follow, eventually leading to one of three practices: 1) users choose to defer tasks until the situation changes, or they abandon the platform altogether; 2) they develop workarounds at different levels of proficiency; or 3) they proceed by reframing their expectations of the platform. By revealing user decision-making process during episodes of disillusionment, the findings contribute to information systems post-adoption research. At a practical level, the findings inform IT artifact and application design by offering insights on how users process discrepancies between their expectations and actual use experience

Superconducting Radio-Frequency Technology: Understanding and Improvements of Limitations Through Application of Cryogenic Instrumentation

A large number of diagnostic methods have been developed during the last two decades to gain insight in limiting phenomena occurring in superconducting rf cavities during operation. Temperature mapping in subcooled and superfluid helium and x-ray mapping have successfully been applied to understand and subsequently prevent or eliminate loss mechanisms present in these devices. Newer techniques specific to problems such as rf window arcing are under development. This paper reviews various diagnostic techniques and discusses the impact of their application on progress made in SRF technology
