This paper should be of interest to the combinatorial optimization community and especially to those interested in the Quadratic Assignment Problem (QAP). The QAP has application in the assignment of facilities to locations (to minimize the cost of intrafacility transportation), the placement of electronic components (to minimize the length of(More)
2 ABSTRACT This paper presents a new strategy for selecting nodes in a branch-and-bound algorithm for solving exactly the Quadratic Assignment Problem (QAP). It was developed when it was learned that older strategies failed on the larger size problems. The strategy is a variation of polytomic depth-first search of Mautor and Roucairol which extends a node(More)
Groundskeepers spend most of the year working outdoors, exposing them to heat and solar ultraviolet (UV) radiation and increasing their risk to related adverse health effects. Various studies on heat and UV exposures in different occupations have been published, but those on groundskeepers are rare. The purpose of this study was to assess the exposure to(More)
Occupational therapy has long had a vested interest in activity programming for the elderly. During the past, this interest has been largely confined to adult day care centers for community dwelling elderly, and to nursing homes for long term care of the elderly. In light of the interest generated by the recent entry of assisted living into the housing(More)

Information about letters and the physical structure of language printed in Roman characters was given to children beginning to read. Experimental investigations coupled three alternative graphic modes of printing upper- and lower-case letters with an instructional intervention termed "Alpha-Beta" which provides practice in letter sorting, matching of(More)
In statistical literature, the term 'signed-rank test' (or 'Wilcoxon signed-rank test') has been used to refer to two distinct tests: a test for symmetry of distribution and a test for the median of a symmetric distribution, sharing a common test statistic. To avoid potential ambiguity, we propose to refer to those two tests by different names, as 'test for(More)
SUMMARY This paper describes the development and use of Lifestyle Management Programs© (LMPs) by occupational therapists at the Multiple Sclerosis Society of New South Wales, Australia. A case study is used to demonstrate how the program is applied in an individual situation. LMPs are used with people with MS, or their support people, to enable management(More)
