An investigation of the strength of aluminum wire used in integrated circuits

Microloop pull test is developed to stress wire loops in situ until failure. The applied loads, the nature of the fracture, and its location are recorded. This test also stresses the wire bonds

Acceptability of medical digital libraries

Evidenced-based medicine has increased the importance of quick accessibility to reputable, upto-date information. Web-accessible digital libraries (DLs) on the wards can address the demand for such information. The use and acceptability of these resources has, however, been lower than expected due to a poor understanding of the context of use. To appreciate the social and organizational impacts of ward-accessible DLs for clinicians, results of a study within a large London-based hospital are presented. In-depth interviews and focus groups with 73 clinicians (from pre-registration nurses to surgeons) were conducted, and the data analysed using the grounded theory method. It was found that clinical social structures interact with inadequate training provision (for senior clinicians), technical support and DL usability to produce a knowledge gap between junior and senior staff, resulting in information – and technology – hoarding behaviours. Findings also detail the perceived effectiveness of traditional and digital libraries and the impact of clinician status on information control and access. One important conclusion is that increased DL usability and adequate support and training for senior clinicians would increase perceptions of DLs as support for, rather than replacement of, their clinical expertise. © 2002, The Continuum Publishing Group Ltd.

The unseen and unacceptable face of digital libraries

The social and organisational aspects of digital libraries (DLs) are often overlooked, but this paper reviews how they can affect users' awareness and acceptance of DLs. An analysis of research conducted within two contrasting domains (clinical and academic) is presented which highlights issues of user interactions, work practices and organisational social structures. The combined study comprises an analysis of 98 in-depth interviews and focus groups with lecturers, librarians and hospital clinicians. The importance of current and past roles of the library, and how users interacted with it, are revealed. Web-based DLs, while alleviating most library resource and interaction problems, require a change in librarians' and DL designers' roles and interaction patterns if they are to be implemented acceptably and effectively. Without this role change, users will at best be unaware of these digital resources and at worst feel threatened by them. The findings of this paper highlight the importance of DL design and implementation of the social context and supporting user communication (i.e., collaboration and consultation) in information searching and usage activities. © Springer-Verlag 2004

Effective ways to use nonpersonal information in healthcare: report from a workshop held at University College London 15-16 April 2004

New information technologies are being introduced in the UK National Health Service as resources for the acquisition of clinical knowledge. These are forcing working practices to adapt and are affecting and challenging perceived roles, relationships and expectations of patients and health professionals alike. Effective ways to use nonpersonal information in healthcare was a two-day workshop hosted by UCL Interaction Centre at University College London intended to provide a forum for practioners and researchers working in the area of clinical health information delivery to come together to discuss access to health information, and to consider how the various challenges and opportunities relating to electronic information provision can be managed most effectively. For the first day of the workshop, the theme for presentations and discussion was information provision for and access by health professionals. Talks were given by Julius Weinberg (City University, London), Roger Slack (University of Edinburgh) and Anne Adams (University College London). The theme for the second day was information provision and access by patients. Presentations were given by Mig Muller (NHS Direct), Jane Wilson (Whittington Hospital and Medi-notes), Andrew Herxheimer (University of Oxford) and Henry Potts (University College London). On both days, delegates formed into three groups for breakout sessions in which they discussed and reported back on: information quality and use, social and organisational context, and user requirements and training in relation to the respective daily theme (health practitioners/patients). This report summerises each of the presentations and the reports by the breakout groups

Contragredient representations and characterizing the local Langlands correspondence

We consider the question: what is the contragredient in terms of L-homomorphisms? We conjecture that it corresponds to the Chevalley automorphism of the L-group, and prove this in the case of real groups. The proof uses a characterization of the local Langlands correspondence over R. We also consider the related notion of Hermitian dual, in the case of GL(n,R)
