- Description: The purpose of the study was to examine the relationships between personality dimensions, sense of coherence and coping styles among working mothers. The OPQ, OLQ and COPE questionnaires were administered to 120 married, working mothers. In view of contrasting results obtained by other researchers regarding the dimensionality of the COPE, its factorial validity and internal consistency were assessed. Exploratory factor analysis indicated that the COPE measured five factors with high degrees of internal consistency. Several personality dimensions and sense of coherence variables correlated significantly with the dependent variables (coping styles). It appeared that these independent variables predicted substantial percentages of the variability in the coping styles.

- Description: Past research has often shown that job satisfaction and job performance are uncorrelated. The current study was an attempt to clarify the relationship by examining the role of affective-cognitive consistency (ACC) to test whether attitudinal consistency affects the strength of the relationship. A secondary objective was to assess whether modified versions of the Overall Job Satisfaction Scale (OJS) and the Minnesota Satisfaction Questionnaire (MSQ), administered to 166 full-time employees from a variety of companies, may be regarded as affective and cognitive measures of job satisfaction respectively. This view was supported by means of exploratory and confirmatory factor analytic results. Overall job satisfaction was measured by a composite of the modified OJS and MSQ, and job performance was rated on a 10-point scale by the employees’ supervisors. Respondents’ scores on the modified OJS and MSQ were then used to form groups that were high or low in ACC. For employees who displayed high ACC regarding their job satisfaction attitudes, medium to large positive correlations between the job satisfaction measures and performance were obtained. In contrast, non-significant correlations were recorded for the low ACC groups. The hypothesis that ACC is a significant moderator of the relationship between job satisfaction and job performance was therefore supported.

The development of an experimental heat transfer enhancement in tube-in-tube heat exchangers

- Description: M.Ing. , Heat transfer enhancement is currently a very popular field of research in heat transfer engineering. Before an investigation of this nature can be performed a suitable experimental set-up is needed to perform the experimental work. The object of this study was to develop such an experimental set-up to be used in determining the heat transfer and pressure drop characteristics of the refrigerant condensing in the inner tube of a tube-in-tube heat exchanger, with water flowing in the annulus. The experimental set-up was built and experiments were conducted with water flowing in the inner tube and annulus. From these readings heat transfer correlations were derived for the water flowing in the inner tube as well as the annulus by using the modified Wilson plot technique.
