Research on computer aided testing of pilot response to critical in-flight events

Experiments on pilot decision making are described. The development of models of pilot decision making in critical in flight events (CIFE) are emphasized. The following tests are reported on the development of: (1) a frame system representation describing how pilots use their knowledge in a fault diagnosis task; (2) assessment of script norms, distance measures, and Markov models developed from computer aided testing (CAT) data; and (3) performance ranking of subject data. It is demonstrated that interactive computer aided testing either by touch CRT's or personal computers is a useful research and training device for measuring pilot information management in diagnosing system failures in simulated flight situations. Performance is dictated by knowledge of aircraft sybsystems, initial pilot structuring of the failure symptoms and efficient testing of plausible causal hypotheses

Navigation-by-music for pedestrians: an initial prototype and evaluation

Digital mobile music devices are phenomenally popular. The devices are becoming increasingly powerful with sophisticated interaction controls, powerful processors, vast onboard storage and network connectivity. While there are ‘obvious’ ways to exploit these advanced capabilities (such as wireless music download), here we consider a rather different application—pedestrian navigation. We report on a system (ONTRACK) that aims to guide listeners to their destinations by continuously adapting the spatial qualities of the music they are enjoying. Our field-trials indicate that even with a low-fidelity realisation of the concept, users can quite effectively navigate complicated routes

Narratives of an outsourced information systems failure in a small enterprise

In this study we investigate a case of an outsourced information systems (IS) failure (OISF) within the collaborative partnership among asymmetric partners. A small and medium-sized enterprise (SME) is dealing with an independent software vendor (ISV) conducting a project of implementing an IS that fails. We used a narrative research methodology for our enquiry. In the construction of our narrative we followed the OISF framework as a theoretical touchstone. As a major conclusion we found that asymmetric collaborations with partners with inadequate managerial and technical IT capabilities are extremely prone to OISF’s. We showed that an outcome-based and fixed price contract is not an adequate instrument to conduct such a partnership and to avoid a failure

A Law Library Development Project in Iraq: Looking Back Two Years Later

Sometimes you get a chance to work on a project so complex, even you don\u27t come to fully understand its impact until years later. At least that has been the experience for me regarding the opportunity I had to work in Iraq with the International Human Rights Law Institute (IHRLI) from February 2004 to January 1, 2006. As I reported in a previous essay, IHRLI, an institute of the DePaul University College of Law headed by Cherif Bassiouni, received a United States Agency for International Development (USAID) Higher Education and Development (HEAD) contract to work with three Iraqi law schools.\u27 The contract was initially proposed as a three-year plan to help Iraqi law schools overcome the effects of more than twenty years of economic, physical, and intellectual isolation. The complete project included a program for clinical legal education, curriculum reform, rule of law, and library and educational technology. All of the goals for the program were extremely ambitious. The situation of the law schools in Iraq really didn\u27t allow for anything smaller in scope. Three law schools were selected-one each from the three major geographic regions of Iraq. The following is a contemporaneous description of the project. It was written about midway through the actual time spent in-country; however, at the time we thought the program was just about to end
