Human population cytogenetic studies have revealed that a majority of persons who are prone to developing malignant features possess chromatin bodies termed as marker dots (MDs) measuring nearly 2 to 3 microns. These MDs are seen emanating from certain specific chromosomes, which may be early indicators of neoplastic transformation within cells.

This study tries to give an answer to the question whether the perceived beneficial images of destinations differ across different travel contexts (wellness vs. sun & beach) and wellness and nonwellness travellers respectively. This objective is demonstrated by considering two sets of destinations: European and Asian countries that are specialising, to a varying degree, in wellness tourism. In addition, the conceptualisation of destination image follows the direction of an ‘overall composite and gestalt impression’ summarised by Keaveney and Hunt (1992, p. 166) that also requires an adequate holistic measurement process. For this purpose the procedure outlined by Tapachai and Waryszak (2000) for developing so-called proxy benefit prototypes for describing the product category of a destination is replicated. Meaningful practical results could be elaborated by profiling destination images of ten different countries from the perspective of the abovementioned traveller segments. Plots from multidimensional scaling (MDS) and consecutive property fitting procedures assisted in visualising the results and competitive relations.

Little research has focussed on nursing home residents with a history including a non-dementia related chronic mental illness (HCMI) that manifested before placement in a nursing home. Data from the 1993 Minimum Data Set for Nursing Home Resident Assessment and Care Screening (MDS) on over 70,000 residents in Kansas, Maine, Mississippi, and South Dakota were used to investigate differences in characteristics and care between these residents and more traditional residents. HCMI residents were more likely to be under 65 years of age, male, Medicaid recipients, less functionally impaired, to exhibit higher levels of problem behaviours, and to receive psychoactive medications and psychological therapy, though therapy prevalence rates were low. These data may indicate that appropriate care for HCMI residents is a concern.

The vertical stratification of bat communities in primary forests of the Central Amazon (80 km north of Manaus, Brazil) was investigated using capture nets in the canopy (17 to 30 m high) and in the understorey (from 0-2.5 m). Seventeen sites were sampled during one year (3398.5 mistnet-hours) and 936 individuals captured, belonging to 6 families, 29 genera and 51 species. Utilizing Non-Metric Multidimensional Scaling (NMMDS), a well-marked vertical stratification between the communities was verified, the canopy being the more utilized region. Fifteen species were exclusively captured in the canopy, 10 were predominantly captured in the canopy, and 12 species were exclus ively captured in ground nets. Species recorded and the communities they form were analysed using a matrix of guilds. The matrix obtained had 24 cells. A guild composed by background cluttered/gleaning frugivores was the richest in species (19), followed by background cluttered/gleaning insectivores (12 species). The results illustrate that when studying tropical forests it is highly desirable to involve both the lower and the upper part of the forests; otherwise the fauna would be merely subsampled, thus under-estimating the status and abundance of some species.

Our concern here, is the characterization of dissimilarity indexes defined over finite sets, whose spatial representation is spherical. Consequently, we propose a methodology (NormedMultiDimensional Scaling) to determine the spherical euclidean representation of a set ofitems best accounting for the initial dissimilarity between items. Thismethodology has the advantage of being graphically readable on individual qualitiesof projection like the normed PCA, of which it constitutes a generalization. Moreover, it avoids the arbitrary character of spherical encoding which the use of similitude functions currently used in MDS, implies.
