  • Description: The development of poly[allylSB-co-EGDMA] beads containing a tetradentate ligand was achieved via suspension polymerization. The catalyst poly[allylSB-co-EGDMA]-VO was synthesized by reacting VIVOSO4 with poly[allylSB-co-EGDMA]. XPS and EPR were used to confirm the presence of vanadium (V4+) on the beads. The synthesized catalyst (poly[allylSB-co-EGDMA]-VO) was found to have a BET surface area of 22 m2 g−1 and porosity of 135 Å, with the atomic force microscopy (AFM) showing more insight on the porous nature of the beads. Oxidation of thiophene (TH), benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) was carried out using tert-butyl hydroperoxide (t-BuOOH) as oxidant. An overall conversion of 60%, 82%, 98% and 87% was achieved for thiophene (TH), benzothiophene (BT), dibenzothiophene (DBT) and 4,6 dimethyldibenzothiophene (4,6-DMDBT) respectively at higher (t-BuOOH) to substrate ratio and at a temperature of 40 °C. The efficient oxidation of the various organosulfur compounds presents potential for the possible application of this catalyst in oxidative desulfurization (ODS) of crude oil. , Original publication is available at http://dx.doi.org/10.1016/j.apcata.2013.05.004

  • Description: Zinc mono carboxy phenoxy phthalocyanine (1) was chemical modified with ascorbic acid via an ester bond to give ZnMCPPc-AA (2). Complexes 2 and 1 were coordinated to single walled carbon nanotubes via π–π interaction to give ZnMCPPc-AA-SWCNT (3) and ZnMCPPc-SWCNT (4) respectively. Complexes 2, 3 and 4 showed better photophysical properties: with improved triplet lifetimes and quantum yields, and singlet oxygen quantum yields when compared to 1 alone. The photodynamic therapy activities of complexes 1, 2, 3 and 4 were tested in vitro on MCF-7 breast cancer cells. Ascorbic acid suppresses the photodynamic therapy effect of 1, due to its ability to reduce oxidative DNA damage as a result of its potent reducing properties. The highest phototoxicity was observed for 4 which resulted in 77% decrease in cell viability, followed by 3 which resulted in 67% decrease in cell viability. This shows the importance of combination therapy, where the phthalocyanines are the photodynamic therapy agents and single walled carbon nanotubes are the photothermal therapy agents. , Original publication is available at http://dx.doi.org/10.1016/j.saa.2015.06.063

  • Description: A new low symmetry, Zn phthalocyanine monosubstituted with diethylaminoethanethiol (mDEAET ZnPc) was synthesized and characterized. This work reports on its photophysical and photochemical properties of mDEAET ZnPc alone and when conjugated to gold coated and uncoated zinc oxide nanohexagons (ZnO NHXs). The photophysicochemical properties generally improved in the presence of the ZnO NHXs. These complexes were also tested for their photodynamic antimicrobial activity against Staphylococcus aureus (S. aureus). The Pc alone showed remarkable growth inhibition even at concentrations as low as 0.05 mg/mL. The conjugates showed a high photoinactivation of S. aureus after 30 min at a fluence of 90 mW cm−2 at a concentration of 0.05 mg/mL. The ZnPc-ZnO NHX conjugates produced the best antimicrobial results. , Original publication is available at http://dx.doi.org/10.1016/j.molstruc.2015.06.088

  • Description: The evidence of entrepreneurship's significant contribution to economic growth and development, challenges the dominance of general equilibrium theory in microeconomics. The assumptions of the neoclassical economic model which underlies general equilibrium theory has long time been criticised; yet its consideration in policy formulation has not been dismissed despite the fact that general equilibrium theory does not incorporate entrepreneurship. The assumptions embedded in neoclassical economic theory exclude entrepreneurship as an economic variable. However, as microeconomic research finds more and more evidence confirming the importance of new business formation and growth, general equilibrium theory remains incapable of adapting to this reality. To this end general equilibrium theory produces policy prescriptions which favour mainly large, established firms over new, small firms. It is therefore no wonder that a large number of small businesses in South Africa are failing. This lecture presents the theory of the firm and also defines an entrepreneur within the context of the theory of the firm. In doing so, this lecture exposes the shortcomings of the general equilibrium theory which is used to explain entrepreneurship. Based on Schumpeter’s description of an entrepreneur, namely, a Disequilibrating factor of economic processes; this lecture demonstrates how entrepreneurship should be understood and developed within a broader scope of microeconomics discourse.

  • Description: Retirement has different meanings for different people. Retirement represents a significant transitional period in the life cycle of an individual. The aim of the study was to explore and describe the experiences and coping resources of retirees. The researcher applied an exploratory, descriptive research design employing the mixed methods of quantitative and qualitative research to gain an in-depth understanding of the phenomenon. A non-probability purposive sampling method was used to identify participants who retired from a specific vehicle manufacturing company in Port Elizabeth. Semi-structured interviewing techniques and a questionnaire called the Coping Resources Inventory were used for data collection. The rationale for using a mixed method approach was to increase the validity of the research findings. Descriptive statistics and the framework provided by Tesch (in Creswell, 2003) were used in data analysis of quantitative and qualitative data respectively. The results of the Coping Resources Inventory indicated that the participants perceived themselves as having an average level of coping resources. The results from the semi-structured interviews reflected that participants’ retirement experiences are mainly influenced by the following three factors: (a) economic resources, (b) social relationships and (c) personal resources. Recommendations were made for future research and intervention regarding retirement planning. The researcher included suggestions for the implementation of a retirement preparation programme. Lastly the limitations and the value of the study were outlined.

  • Description: The FAWU research unit has been operating in the Head Office since 1998. It has established a resource centre and has two people working in it at this time - Thandi Yoli and Viva Mtai. The unit was jointly conceived in 1996/97 by FAWU and the Labour Research Service (LRS). The relationship between the two organisations continues presently, and will last until the research unit is properly established and resourced within FAWU's head office. The LRS successfully applied for funding for the project in 1996/97 from the FNV-Holland. This money goes to paying the salaries and overhead costs incurred by the LRS for providing a senior researcher (Reza Daniels) to supervise and establish the research unit in FAWU. It is a three-year project and we are currently in the third year of the project. We are, however, going to apply for an extension of the project (to the FNV-Holland) so that it is completed by the end of the year 2000. The original aim of the project in 1996 was to assist FAWU to increase its bargaining capacity by developing a research unit that was targeted to producing sectoral reports that could assist the bargaining department. It was felt that FAWU lacked the research capacity to fully support its bargaining structures because of several factors.

  • Description: The human resource department in many organisations is at a crossroad of relevance, constantly being faced with the challenge to prove that it can add value towards the objectives of the business. The Human Resource (HR) department is also faced with a reality that, if the department does not add value to the organisation, it will be farmed out to independent contractors, who can deliver the HR functions at a more efficient and cost effective way. However, organisations have a great opportunity to achieve excellence and competitive advantage through the utilisation of the organisation‟s human resources. Many scholars and authors argued that organisations can achieve the most out of its human resources if the HR department is a Strategic Business Partner (SBP) in these organisations. A thorough literature review has led to the discovery that, despite the appraisal of the Strategic Business Partners (SBP) approach to the management of human resources, little progress has been made with the reinvention of the HR departments from support function towards being a SBP (Lawler & Morhman, 2003; Keith, 2007). The slow progress in the transformation of the HR department was attributed to a wide range of factors including the lack of competencies to take up Strategic Business Partnership roles, lack of management support, and incongruent organisational cultures (Keith, 2007; Sanders & Frenkel, 2009; Ulrich & Brockbank, 2005). Semi-structured interviews were conducted with HR professionals, Managing Directors and other Directors, who sit on a strategic table, to identify the challenges and opportunities the HR department faced as a SBP in organisations. A self-administered questionnaire, based on an existing questionnaire (Ulrich & Cornell (1997) HR role assessment survey) was used to gather the perception of employees regarding the roles the HR departments play in organisations. In this study organisational culture was identified as having a huge impact towards the implementation of HR departments as SBPs. The study also identified the competencies needed for the effective execution of SBP roles, the challenges HR departments may face in the process as well as the important roles the HR department should be devoting most of its time and resources to.

  • Description: Black people live and work in very poor conditions in South Africa. They have always protested and resisted this. But at the beginning of this century, these protests were limited to a few groups of workers at any one time. There was no organisation for black workers. Then, soon after the First World War ended, a new movement appeared. It spread through the land like a veld fire. The people began to talk of their liberation, their new leaders and their organisation - the Industrial and Commercial Union (the I.C.U.). As a farm labourer from Standerton said:"Man we thought we were getting our country back through Kadalie."
