The aim of this research is to develop a conceptual model consisting of factors which were associated with managerial success in a changing environment and to investigate its predictive validity. This "Successful Manager Profile" contains three domains, each consisting of a number of factors. An assessment battery was devised to measure the three domains - cognitive abilities, personality variables and personal competencies - of the "Successful Manager Profile." A sample of 287 employees was assessed during 1991 and 1992 using assessment centre technology, psychometric tests and questionnaires. Five years later (in 1996 and 1997), criterion data, which consisted of the final organisational level attained, were collected. The research question - whether the variables contained in the "Successful Manager Profile" - was investigated using Stepwise Multiple Regression analysis. The coefficient of multiple determination reported ranged from R2+0.21 for the total sample to R2=0.60 for the male graduate group. / Industrial Psychology / M. Comm. (Industrial Psychology)

The relative advantages or disadvantages associated with the practice of grouping school children according to ability level has long been the subject of considerable discussion among educators. The general tendency has been for educators to divide into two camps: Those who expound the various merits of homogeneous grouping, and those who favor and support heterogeneous grouping practices, Less common, but acknowledged, are those educators who favor a combination of the two methods. Research dealing with the relative value of either method has usually been concerned with only one aspect of the problem--that of academic achievement. However, the.efforts of several investigators (Luchins and Luchins, 1948; Mathias, 1959; Tonsor, 1953) have suggested that different grouping practices may have differential effects upon the social adjustment and personality development of the pupil as well. As the total development of the child is of primary importance in the educational process, an investigation of the differential effects inherent in either of these methods of grouping would seem to be of value.

The primary aim of the research has been to determine whether there is a relationship between personality variables as measured by the Occupational Personality Questionnaire (OPQ32i) and the work performance of credit controllers in a bank. Work performance was measured by means of internal company data sources. A literature review was used to verify whether there is a theoretical relationship between personality and work performance and strong evidence was found. The sample consisted of 89 credit controllers. The relationship between personality variables and work performance was determined by means of correlation studies and multiple regression analyses. Results are reported both in terms of statistical significance and effect sizes. Key terms: personality, work performance, credit control, personality trait theory, Sixteen Personality Factors questionnaire (16PF), Occupational Personality Questionnaire (OPQ). / Industrial and Organizational Psychology / M.Com.
