Parts Of The Whole: Observing The State Of The System, Dorothy Wallace
Parts Of The Whole: Observing The State Of The System, Dorothy Wallace
Numeracy
This column draws on the approach of statistician J. Edwards Deming to analyze sources and consequences of variation in an education system. Educational systems are not immune from the effects of poor statistical control, which makes it difficult for teachers to teach effectively and for managers such as principals to improve on school performance. It is also argued that the need for statistical control in these areas is in tension, if not outright conflict, with our goals for educating students.

Theses and Dissertations
Scan-based near-field acoustical holography (NAH) is applied to partially correlated sources. Partial field decomposition via the virtual coherence method is used to implement the scan-based NAH. The background and theory of these methods are developed. Multiple stationary reference microphones are required for the partial field decomposition. Guidelines for reference microphone placement in the literature thus far have been limited. Improved guidelines for reference microphones are given after the results of two sets of experiments. The first set involves discrete, partially correlated sources, both physical and numerical. The second set of experiments is strictly numerical and involves continuous sources. Fewer microphones …

The life cycle of the Southeast Asian–western North Pacific monsoon circulation is established by the northward migrations of the monsoon trough and the western Pacific subtropical anticyclone, and is reflected by the intraseasonal variations of mo nsoon westerlies and trad e easterlies in the form of an east–west seesaw oscillation. In this paper, an effort is made to disclose the influence of this monsoon circulation on tropical cyclone tracks during its different ph ases using composite charts of large-scale circulation for certain types of tracks. A majority of straight-moving (recurving) tropical cyclones appear during weak (strong) monsoon west- erlies and …
