Disgust is a primary emotion relevant to both clinical and social psychology. However, the current most popular disgust measure has serious psychometric weaknesses (Haidt, McCauley, & Rozin, 1994). Furthermore, no extant measure assesses moral disgust as an emotional response to moral transgressions. The purpose of the present research is to develop a new measure, the Sensitivity to Disgust Measure (SDM). Data from 598 participants ranging in age from 21 to 83 years shows that the SDM measures disgust responses to stimuli from five elicitor domains: body products, body envelope violations and death, animals, sex, and moral transgressions. The alpha coefficient for the total scale is .90; and the coefficients for the subscales range from .78 to .87. Criterion-related validity analyses show that SDM scores predict responses to the Haidt et al.'s (1994) Disgust Scale, the Contamination Subscale of the Padua Inventory, the PANAS, and the Neuroticism, Agreeableness, and Openness subscales of the Big Five Model. / Department of Psychological Science

Surface layer coatings, which are thin films in the range of micrometer and nanometer are of utmost importance. These layers have many applications and control processes like corrosion, friction, wearing and adhesion. Therefore the search for layers with satisfactory surface properties for different applications is needed. Thickness measurements were evaluated in this study using PIXE in conjunction with RBS. Different samples were evaluated using both the solid-state chamber and the nuclear microprobe. The energies of 2.0 MeV alpha particles, 2.5 MeV and 3.0 MeV protons were used in this study. RBS when compared to PIXE showed low sensitivity towards light elements. The High purity Germanium detector also found it difficult to resolve peaks of elements (Magnesium and. Aluminum) that were close to one another. The GeoPIXE software showed inconsistent results for all the measurements. However the results showed good agreement between the two techniques. The overall observation of the study was that PIXE has shown its ability to measure thickness and that the inconsistency in the results from GeoPIXE software makes it difficult to trust the software for analysis of the results. / MSc (ARST) North-West University, Mafikeng Campus, 2003

The definition of the shape of the geoid is a fundamental objective of geodesy, since it allows for the conversion between orthometric and ellipsoidal height systems. The geoid can be computed from gravity values measured over the surface of the earth, and considerable effort continues to achieve a global coverage of gravity values. One technique that has been very successful in recent years in providing gravity coverage in areas which previously have been too difficult to access is airborne gravimetry. This technique has proved very useful in covering near offshore regions, for example. The coastal regions of Australia are recognised as locations where airborne gravimetry has the potential to fill in missing gravity data. A pilot survey using an airborne gravity meter was undertaken off the north east coast of Australia. In areas that remain unsurveyed it is sometimes useful to fill in the missing gravity data values with predicted gravity values. Previous research has examined the possibility of predicting gravity values from other observed quantities. The best success has been achieved by using the gravity effect calculated from bathymetric information. Often the corresponding isostatic compensation is computed, and the combined bathymetric-isostatic gravity effect is used. However, the type and extent of compensation that exists in any particular region mostly remains unknown. Theoretical considerations indicate that the short wavelength part of the gravity field may be adequately modelled by the gravity effect of the bathymetry alone, without reference to an assumed compensation mechanism. With this in mind, a prediction scheme has been developed which utilises the short wavelength gravity field information implied by the bathymetry, combined with the long wavelength gravity field information from existing observed gravity. This scheme allows the prediction of ???fill-in??? gravity values in areas with limited observed gravity. The prediction technique was used on a test set of data off the east coast of Greenland. The prediction technique was seen to outperform a simple interpolation of gravity values by approximately ten percent. Geoid computations performed with the predicted gravity values indicate that the prediction technique can provide significant improvements in computed geoids.
