The Keldysh theory of above-threshold ionization (ATI) is applied to few-cycle laser pulses in order to explore the potential of a recently published new method to measure "carrier-envelope phase difference" phenomena. In this experiment, the carrier-envelope phase difference dependent left-right asymmetry of few-cycle ATI was measured and investigated with a correlation technique. Here, we explore spectral features of the asymmetry, present a theoretical analysis of the experiment, and establish a method to determine the duration of few-cycle pulses whose carrier-envelope phase differences are not controlled.

This paper reports the results of an empirical examination of the effectiveness of two knowledge discovery tools (barchart and scatterplot) in the context of a sales forecasting task. The main results of the study indicate that both tools were reasonably suitable for well conveying associations among task variables and offering improvements in prediction accuracy when compared to a naive predictor. There is however, still much ground for improvement towards a theoretical optimal case. In addition, findings show that a scatterplot was significantly more beneficial than a barchart in enhancing forecasters’ knowledge and performance of the task. This superiority can be potentially explained in terms of the favorable aspects of Cartesian graphs and the greater concentration required for using the tool.

Few would refute the importance of harnessing organizational knowledge — for reuse, learning, and process improvement. Once retained in a concrete form, knowledge becomes less fragmented and more easily accessible and useable. Such a knowledge management system indeed becomes a source of competitive advantage for an organization. The key to achieving this is by retaining the existing organizational knowledge so that we do not have to rely solely on available expertise. A number of knowledge management frameworks exist which help us to classify and structure knowledge. No single framework dominates, because different organizations have different needs depending on factors such as culture and business processes. At the same time, there is a lack of case studies on how organizations create or operate such a knowledge management system. In this paper, we present a case study of a knowledge management system used in a specific context — an Australian construction company. The study shows that, at least in this particular context, a knowledge management system can operate only where it does not interfere with the existing workflow of the organization. Furthermore, the importance of retaining valuable tacit knowledge is emphasized. We also discuss the implications for future research and practice.

Although we agree that care in the community is perceived as a failure within the public domain and definitively as portrayed by the media, there are a number of issues around deinstitutionalisation that have not been addressed by Professor Leff ([2001][1]). Certainly, the apparent invisibility of
