The Effects of Common and Uncommon Elements on the Emergence of Simple DiscriminationsNiland, Haven Sierra 05 1900 (has links)
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 validation of the perceived wellness survey in the South African Police Service / Jolanda EkkerdEkkerd, Joland January 2005 (has links)
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.

Equivalence Classes of Cauchy Sequences of Rational NumbersDarnell, Linda Jane 01 1900 (has links)
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.
