A FIELD TRIP AS PART OF THE SOCIAL WORK RESEARCH MODULE

This study focused on the value of a field excursion for final-year Social Work students as part of the research module with the aim of integrating the theory and practice of research. Students were expected to do unstructured interviewing with older persons in a deep rural community, with the main focus of the study being on the impressions and experiences of the students. Seven main themes were delineated in this study according to narratives given by participants, namely Social Work and research, feelings of the researcher, knowledge of the self, resilience, infrastructure, challenges facing the community and future perspectives

Substance abuse and the workplace : a situation analysis

Substance abuse among the employed in South Africa has increased in recent years with major economic consequences for employers. Specialist outpatient treatment programmes are available to employers, yet few employees are inducted into these programmes. A situation analysis was conducted to explore possible reasons for this state of affairs. This article provides an overview of workplace-related limiting factors in combating substance abuse and also covers the resources needed to deal with the problem of substance abuse in the workplace. The authors suggest collaboration between employers and outpatient treatment centres as a viable solution

SUBSTANCE ABUSE, DEPENDENCE AND THE WORKPLACE: A LITERATURE OVERVIEW

Substance abuse and dependence among the employed have massive cost implications for South Africa. Employers are legally obliged to provide opportunities for the treatment of substance dependence before dismissal is considered. Problem areas are the following: inadequate identification of employees with substance-abuse problems, infrequent treatment referrals, and overlooking of substance abuse in the workplace. This article attempts to address these issues by providing an overview of literature dealing with the problem of substance abuse and dependence in the workplace. Addressing this problem calls for specialist intervention measures, which are discussed in the article

Influence of Fermentation Medium Composition on Physicochemical Surface Properties of Lactobacillus acidophilus

The effect of the simple and complex basic components of a fermentation medium on the surface properties of Lactobacillus acidophilus NCC2628 is studied by physicochemical methods, such as electrophoresis, interfacial adhesion, and X-ray photonelectron spectroscopy, and by transmission electron microscopy. Starting from an optimized complete medium, the effect of carbohydrates, peptones, and yeast extracts on the physicochemical properties of the cell wall is systematically investigated by consecutively omitting one of the principal components from the fermentation medium at the time. The physicochemical properties and structure of the bacterial cell wall remain largely unchanged if the carbohydrate content of the fermentation medium is strongly reduced, although the concentration of surface proteins increases slightly. Both peptone and yeast extract have a considerable influence on the bacterial cell wall, as witnessed by changes in surface charge, hydrophobicity, and the nitrogen-to-carbon ratio. Both zeta potential and the cell wall hydrophobicity show a positive correlation with the nitrogen-to-carbon ratio of the bacterial surfaces, indicative of the important role of surface proteins in the overall surface physical chemistry. The hydrophobicity of the cell wall, which is low for the cultures grown in the complete medium and in the absence of carbohydrates, becomes fairly high for the cultures grown in the medium without peptones and the medium without yeast extract. UV spectrophotometry and sodium dodecyl sulfate-polyacrylamide gel electrophoresis combined with liquid chromatography-tandem mass spectrometry are used to analyze the effect of medium composition on LiCl-extractable cell wall proteins, confirming the major change in protein composition of the cell wall for the culture fermented in the medium without peptones. In particular, it is found that expression of the S-layer protein is dependent on the protein source of the fermentation medium
