A computerized program was designed to test whether arranging a common element in two, otherwise independent, 2-term correlations (stimulus-stimulus and response-stimulus) would result in emergent simple discriminative-stimulus properties for the antecedent stimulus relative to an arrangement with no common elements programmed. Data from 8 adult participants in this experiment indicate that common element arrangements led to relatively high rates of responding in the presence of the putative discriminative stimulus and relatively low rates or no responding in the presence of the putative s-delta during testing in extinction. Conversely, the uncommon element arrangements produced no clear discriminative control. The current data reflect a comparison of arrangements across subjects. These data support Sidman's (2000) suggestion that common elements among contingencies are sufficient to produce stimulus classes and cause class mergers. The data also have implications for thinking about the mechanism by which and the conditions under which discriminative control develops. Finally, these data have the potential to inform the programming and implementation of reinforcement contingencies in applied settings.

The era of globalisation calls for a flexible, multi-skilled, knowledgeable, inter-changeable and adaptable healthy workforce. Employee wellness is essential to ensure an effective and efficient workforce. It is important. however. to measure wellness before it can be developed. Currently there is a need for a measuring instrument in South Africa which can measure all the dimensions of wellness as conceptualised in the literature. However, it is risky to apply psychometric instruments developed in other cultures to the South African contest without validating it. The objective of this study were to validate the Perceived Wellness Survey (PWS) in the South African Police Service (SAPS) The specific objectives of the study. included to conceptualise perceived wellness and the dimensions thereof from the literature to access the internal consistency and construct validity of the PWS in a sample of police personnel and to investigate differences in the perceived wellness of biographical groups. A cross-sectional survey design with an accidental sample (N=840) of police personnel was used. The sample was composed of personnel from multiple divisions in the SAPS, including Functional as well as Public Service Act personnel. The Perceived Wellness Survey (PWS) and a biographical questionnaire were administered. Descriptive statistics, principal component analysis, target rotations, alpha coefficients and multivariate analysis of variance were used to analyse the data. Exploratory factor analysis with target rotations failed to confirm the construct equivalence or the PWS for Afrikaans and Setswana language groups. Two reliable factors. namely wellness and illness were extracted in a random sample (n = 335) of the Setswana group and in a replication sample (n=338) However. an alternative interpretation was also possible. Statistically significant differences were found between perceived wellness of employees in terms of age and rank. Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2006.

The purpose of this thesis is to define equivalence classes of Cauchy sequences of rational numbers and the operations of taking a sum and a product and then to show that this system is an uncountable, ordered, complete field. In so doing, a mathematical system is obtained which is isomorphic to the real number system.
