- Description: The main objective of the present study was to determine the relative role and importance of worsted suiting fabric fibre blend vis-à-vis fabric structural parameters, on the comfort related properties of 12 clothing ensembles, each comprising a different man’s suit, but the same wool/nylon underwear and cotton shirt. To achieve the objective, the comfort related properties, namely thermal resistance (Rt) and water vapour resistance (Ret) and water vapour permeability index (Im), of the clothing ensembles, as determined by means of WalterTM, a thermal sweating fabric manikin, were subjected to multi-linear and multi-quadratic analysis, as dependent variables, with the various suiting fabric parameters, namely weight, thickness, density, porosity, air permeability and wool content, as independent variables. It was found that the multi-quadratic regression analysis was able to best explain the observed differences in the clothing ensemble comfort related properties, in terms of the differences in suiting fabric properties. The regression analyses were used to isolate and quantify the effects of the various fabric and fibre content variables on the above mentioned comfort related properties of the various clothing ensembles. This study indicated that the suiting fabric structural properties (notably air permeability), had a more significant influence than either fibre blend or suiting fabric, as measured on WalterTM, a thermal sweating fabric manikin.

- Description: This study seeks to provide insight into the potential that motivation has in improving, not only on service delivery but the personal willingness of employees to perform as well. Continuous improvement is aided by conducting studies of this nature, in an organisation, at pre-determined periods. Municipalities across the country are plagued with complaints regarding service delivery issues. The municipality under study is no different. Newspaper articles like the one in Appendix G depict the stories of communities that are reliant on services provide by local government. There are a range of problems that can lead to municipal service delivery being hampered. One of the problems can be a de-motivated workforce. Human Resources Management needs to find ways of instilling motivation in employees in order to get maximum performance from them. Motivation is influenced by a variety of factors and the Human Resources Management section must look into the influence of these factors on motivation. Studies looking into the constructs of these factors must be conducted. The findings of such research can assist in making positive change in the organisation. The expected motivating factor would be remuneration or financial reward for work done. This may be one of the factors but there is also a range of other factors to be considered. Some of these factors relate to the psychological aspect of motivation. It is important to formulate sustainable ways of motivating employees and these may not be simply raising salaries. This research looked into specific factors of motivation. This is due to the fact that an attempt to cover all factors would simply be too lengthy an exercise. It became necessary to remain within a specific framework. This also assisted in maintaining the quality of the research undertaken.
