Measuring work-home interaction : a validation of the Survey Work-Home Interaction Nijmegen (SWING) instrumentSource: Management Dynamics : Journal of the Southern African Institute for Management Scientists 14, pp 2 –15 (2005)More Less
The objectives of this study were to validate the Survey Work-Home Interaction - Nijmegen (SWING), to assess its item bias and construct equivalence for different language groups; and to analyse the differences in workhome interaction among various demographic groups of workers. A eross-sectional survey design was used. Random samples (n = 326) were taken of workers employed in the eanhmoving equipment industry in eight provinces of South Africa. An exploratory factor analysis showed that the SWING consists of four factors, namely Negative Work-Home Interference, Negative Home-Work Interference, Positive Work-Home Interference, and Positive Home-Work Interference. The four factors showed acceptable internal consistencies. No evidence was found for uniform or non-uniform bias of the items of the SWING for different language groups. Exploratory factor analysis with target rotations confirmed the construct equivalence of the work-home interaction construct. Males experienced practically significant higher negative Work-Home Interference than females.
A psychometric assessment of the Maslach Burnout Inventory (General Survey) in a customer-service environmentSource: Management Dynamics : Journal of the Southern African Institute for Management Scientists 14, pp 16 –28 (2005)More Less
The objectives of this study were to validate the Maslach Burnout Inventory General Survey (MBI-GS) for a customer-services environment, and to assess differences in the burnout levels among various demographic groups. A cross-sectional survey design was used. A sample (n = 228) was taken of customer-services personnel working for medical schemes. The MBI-GS and a biographical questionnaire were administered. Structural equation modelling (SEM) confirmed a three-factor model of burnout, consisting of Exhaustion, Cynicism, and Professional Efficacy. All three factors showed acceptable internal consistencies. The results obtained from comparing burnout levels of various demographic groups showed that no practically significant burnout differences, existed among of employees of different race groups, genders, or organisations.

While certain assets classes have done exceedingly well over the last few years, South African retirement funds yielded below-par investment performance. The important question, therefore, is whether fund managers have been weighing the different asset classes in their portfolio compositions optimally and have been sufficiently able to read the inflationary signs present in the market.
This study attempts to shed some light on the above. The theoretical return of different asset classes, with specific emphasis on cash and property, is considered during three different inflationary eras in South Africa. The degree of convergence of asset returns due to investor substitution among asset classes over the long term is also considered. The return and the risk of property investments in South Africa are compared empirically to the other asset classes from 1980 to 2002. The results indicate that cash outperformed the other asset classes on a risk-adjusted basis.

In a rapidly changing organisational context, there is a need for up-to-date and relevant theory to guide management practitioners' thinking and practice. In this study it is argued that grounded theory has the potential to generate new theories that are based on the current and substantive realities experienced by many management practitioners. The origin, purpose and primary characteristics of grounded theory are briefly discussed, followed by an identification of the use of grounded theory in various studies related to management. Thereafter, the use of the Straussian version of grounded theory is examined, including an explanation of what makes for quality research when conducting grounded theory research, followed by an illustration of the use of grounded theory in a study of change management by strategic leaders of churches.
