  • Description: The aim of this study was to assess challenges in Public Appointments and Recruitment Processes in Chris Hani District Municipality: A case study of Human Resource Department in Lukhanji Local Municipality (2008-2010) of the Eastern Cape Province. There has never been a detailed research study conducted in the Chris Hani Human Resource Department, regarding the subject in question. The Constitution of the Republic of South Africa in Section 195(i) directs that Public Administration must be broadly representative of the South African people, with employment and personnel management practices based on ability, objectivity, fairness and the need to redress the imbalances of the past to achieve broad representation. The literature review explored extensively the models used in implementing recruitment and appointment processes globally. From those tested models elsewhere, it was evident that South Africa has a great Constitution and good policies regarding Local Government Human Resource Department recruitment and appointment processes not withstanding some challenges cited in the study. This assessment of challenges in the public appointments and recruitment processes in Chris Hani District Municipality assisted in the establishment of the real facts about effective and fair recruitment and appointment processes in the Local Government Human Resource Management Department to deserving communities. It became clear from the study that providing efficient and fair recruitment and appointments processes to the Local Government Human Resource Department in South Africa requires a broader advocacy agenda encompassing the development of Human Resource systems and the generation of numerous skills and expertise to deliver services to the poor people of our country.

  • Description: A study on assessing communication challenges between clerks and deaf patients at Nelson Mandela Academic Hospital was conducted in 2010. The aim was to assess the existence of communication challenges, possible reasons and solutions to these. The literature reviewed identified a gap in the knowledge of communication between staff and deaf patients. A health systems’ study was conducted using a descriptive, cross sectional survey. The study population was made up of 33 clerks who worked at the registration and records area and deaf patients who stayed at Efata and received health services from the hospital. All clerks were interviewed and a random sample of 106 deaf patients was estimated using Epidat statistical software. Self administered questionnaires were used for data collection. Results confirmed the existence of communication challenges between the two groups. A majority of clerks were not trained in Sign Language. They used a combination of methods to communicate with deaf patients, and few clerks could use Sign Language. The patients also used a combination of methods due to the frustration of not having a common method of communication with clerks. The findings clearly showed that there are communication challenges between the two groups and Sign Language needed to be introduced to clerks in order to accommodate deaf patients. Further research may be done on all healthcare providers and to all deaf patients in the region served by Nelson Mandela Academic Hospital, and this could have a positive impact on the quality of service offered by the hospital to the deaf community.

  • Description: Human resource management, or people management, is concerned with the philosophies, policies, programmes, practices and decisions that affect the people who work for an organisation. The various people management functions are aimed at helping the organisation achieve its strategic goals and as such are an integral part of the management process. People management consists of several aspects and sub-divisions of which pro-active conflict handling and management is one and which is also the subject of this study. The objective of this study was to assess causes of conflict and interventions and styles of conflict management in the workplace. Workplace politics, change management, diversity, cultures and religious views are but a few major sources for the emergence of conflict. We are currently in the era of fast change or more aptly put “hyperchange” and conflict is inevitable and management styles can also create and/or escalate conflict situations including, the composition of diversity in the workplace. This adds to the new challenges of management. Organisations in this decade need to acknowledge that their management styles of days gone by are not relevant anymore and one must understand to recognise conflict and resolve it in an appropriate manner. This study assessed the major causes of conflict in the workplace and whether the managerial style of managers and management interventions impacts on the overall conflict situations experienced by staff members in organisations in Cape Town and Windhoek. It also gave an indication if interventions and conflict management training/programmes are in place or used, if at all. Sometimes conflict is resolved successfully or unsuccessfully and what impact it has on the managers, his/her staff and colleagues and the organisation as a whole. This can have a detriment impact on the business and the culture within the organisation and which could result in or give rise to high labour turnover, underlying unhappy staff and disempowerment of managers and staff and poor production and service levels.

  • Description: The 21st century has seen nations becoming more competitive yet ironically more interdependent as their future becomes even more dependent on the knowledge, skills, and resourcefulness of its people, creating new opportunities and difficulties for education, (Power, 2000). The education-work-society interdependency has therefore become more important now than ever. It is also because of this triad-interdependency that tertiary education‟s relevance to industry needs has become a crucial issue in societal development. The ever changing needs of South Africa, the unemployment rate, introduction of new technologies and many other ripple effects of globalization have seen more and more pressure mounting on the South African education system as more and more people try to ensure that the education system answers the crucial challenges of the country today and tomorrow.The discussion below provides a detailed account of the context, in which this discourse on curriculum relevance takes place, highlighting some relevant cornerstones of the Reconstruction and Development Programme, (RDP, 1994). Furthermore, this chapter exposes the key research questions and significance of the study. The subsequent chapter 2 gives an account of what other scholars have said on issues of curriculum relevance, development and the South African Higher Education system. Chapter 3 explains the research methodology as a research process used to investigate the problem in question. In this research study the researcher uses both quantitative and qualitative design (online surveys of three groups, these are the graduates, prospective employers and the lecturers). The analysis is based on quantitative data and further substantiated through qualitative data analysis. The subsequent chapter tabulates and lays out the results according to the surveys. The final chapter discusses the findings and makes future recommendations.

  • Description: Community participation is an important aspect of South African government policies that deal with integrated development planning and sustainable development. This report presents aspects of community participation in infrastructure delivery and in particular housing in Reeston which is part of the Duncan Village Redevelopment Initiative in East London area of the Buffalo City Metropolitan Municipality. The importance of community participation is acknowledged as it enhances the ability of the community members to demonstrate and use their own views to deal with specific issues and to address the needs and problems that emerge and prevail in their societies. The two emerging paradigms of community participation suggest that the participating communities should be involved in the ‘selection, design, planning and implementation’ of projects that will have an effect on them and from which they are going to benefit ; and that continuous feedback to communities forms a fundamental part of any development activity. This report explores how the “Breaking New Ground in Housing” (BNG) policy of the South African Government meets its objectives in the context of community participation.

  • Description: The South African local government is expected to conform to all national policy directives including the principle of gender equality. Local government provides an immense opportunity for redressing imbalances and empowerment of women as they are the most negatively affected by poverty as a result of inequality. The South African Government has developed a wide range of legislation that ensures that women are empowered and participate in their own development. With all the legislation in place, women‟s empowerment as envisaged in the South African Constitution has, however, not yet been yielded the desired results as evidenced by the fact that women continue to remain disadvantaged in relation to men. This study therefore seeks to investigate whether and how the Nelson Mandela Bay Metropolitan Municipality (NMBMM) has mainstreamed gender in support to the principles of gender equality and women‟s empowerment in the implementation of Integrated Development Planning (IDP) with particular reference to wards 15 and 17. The researcher used a mixed methods research approach, this means that the study followed both the qualitative and quantitative approaches for in-depth understanding followed in the design and implementation of the IDP process. Data was collected from women participants by conducting surveys, making use of questionnaires. Structured interviews were conducted with municipality officials in order to give more insight more insight into how the IDP process is initiated in the Nelson Mandela Bay Metro Municipality. The findings of the study revealed that there is a lack of a strategic understanding of gender mainstreaming particularly by the leadership of the municipality. This as a result, has made operationalisation and engendering the IDP difficult. Due to this strategic vacuum, gender is generally not taken seriously when compared to other developmental challenges such as infrastructure provision. Moreover, the municipality does not have a coordination mechanism nor does it have a proper consultation mechanism to ensure that the nature of development projects is appropriate, effective and actually targets women‟s developmental needs. The leadership of the municipality must commit to the process of gender mainstreaming if the IDP is to be an effective tool in addressing the gender imbalances.

  • Description: Lean manufacturing provides a fundamental basis for competitiveness in the auto component sector. The implementation and sustainability of the lean philosophy are important aspects when deciding on the adoption of the lean concept within organisations. Various barriers to implementation present themselves during and after lean implementation. These barriers are often related and in some instances they may be converted from an impediment into an enabler of lean within companies. The impact of unions as a negative or positive influence forms a central focus of this research. The influences on the perception of unions and their constituents are studied in relation to other barriers in order to determine their relevance in the Eastern Cape auto sector. A research questionnaire was constructed in line with the selected research design. The application of triangulation in the research design allows for greater depth in the responses from the participants in this research. The quantitative analysis combined with the qualitative thematic analysis provides an excellent means to explore and understand these selected barriers to lean in great detail. It can be concluded that automotive trade unions in the Eastern Cape are a barrier to implementation; however the factor that influences lean the most is the incorrect perception of lean due to ineffective leadership practices among organisational and union leaders, among other barriers. The impact of unions on the acceptance of a lean culture has far-reaching implications for the auto sector that requires a specific implementation approach in order to change perceptions and gain the requisite interest alignment among unions and their constituents.

  • Description: The aim of this study was to examine the effectiveness of a capacity development programme initiated by the Department of Economic Development and Environmental Affairs (DEDEA) as a mechanism to enhance the performance of the employees in order to improve service delivery to the people of the Eastern Cape. The public service is enjoined by the Constitution to provide services that citizens need, and for this reason it is in need of educated, trained and professional public servants, especially in the technical, professional and managerial categories. The department also recognized the potential of public–private partnerships (PPPs) to improve performance in the areas of transformation and service delivery, and that it required investments aimed at developing and strengthening public management capacity. However, the effectiveness of the PPP as a mechanism for capacity development, remained unknown. The literature reviewed overwhelmingly supported the assertion that human capital development is critical for performance in the public service. The review also highlighted the importance of partnerships, especially the role of the private sector in the area of capacity development, advancing the argument that PPPs should be pursued in order to leverage ideas, resources, and capabilities to achieve public service goals. Various research tools, namely interviews, questionnaires and document analysis were used to conduct the study. Data collected and analysed provided empirical evidence of improved performance of both the individual managers and the department in the functional areas of financial governance and management; programme and project management; as well as ethics and professionalism. It suggested a strong correlation between training, capacity development and service delivery. This research found the DEDEA/National Business Initiative (NBI) PPP initiative, as a capacity development mechanism to enhance the performance of the department‟s employees, effective. On strength of the overwhelming evidence gathered through this research, it strongly recommends that the programme be rolled out to other employees.

  • Description: This thesis presents an evaluation of the dispersive solid-phase extraction (d-SPE) method referred to as the quick, easy, cheap, effective, rugged and safe (QuEChERS) method for the determination of four organochlorine pesticide residues in fish samples. The pesticides investigated in this study were o, p′-DDT, p, p′-DDE, aldrin and dieldrin. The combined use of Gas Chromatography with an Electron Capture Detector (GC-ECD) and sensitive Time of Flight (TOF) mass detector facilitated the identification of the target analytes. In the absence of certified reference material, the overall analytical procedure was validated by systematic recovery experiments on spiked samples at three levels of 2, 5 and 10 ng/g. The targeted compounds were successfully extracted and their recovery ranged from 76 to 96% with relative standard deviations of less than 13%. The optimum QuEChERS conditions were 2g of fish powder, 10 ml acetonitrile and 1 min shaking time. The optimal conditions were applied to assess the levels of chlorinated pesticides in blunt-tooth catfish (Clarias ngamensis), tigerfish (Hydrocynus vittatus), Oreochromis andersonii and red-breasted tilapia (Tilapia rendalli) from the Okavango Delta, Botswana. Dieldrin, p, p′-DDE and aldrin were detected in all the analysed samples with a concentration range of 0.04 – 0.29, 0.07 – 0.33, 0.04 – 0.28 and 0.03 – 0.24 ng/g per dry weight in O. andersonii, C. ngamensis, T. rendalli and H. vittatus respectively. These concentrations were below the US-EPA 0.1 μg/g allowable limit in edible fish and the Australian Maximum Residue Limit (MRL) of 50 - 1000 ng/g in fresh fish. DDT was not detected in all the fish species investigated. The mean lipid content recorded in the fish samples were 1.24, 2.16, 2.18 and 4.21% for H. vittatus, T. rendalli, O. andersonni and C. ngamensis respectively. No systematic trend was observed between fish age and pesticide levels in fish. Acetylcholinesterase (AChE) activity assays were performed to assess the effects of organochlorine pesticides in Clarias ngamensis. The enzyme activity recorded in Clarias ngamensis from the Okavango Delta and the reference site was 12.31 μmol of acetylcholine iodide hydrolysed/min/g brain tissue. The enzyme activity remained the same indicating no enzyme inhibition. The conclusions drawn from this study are that the QuEChERS method is applicable for the determination of organochlorine pesticide residues in fish matrices. The fish from the Okavango Delta are safe for human consumption.

  • Description: Cocos nucifera belong to the family Aracaceae (palm Family). The English name is coconut and it is used extensively as medicinal remedies against infections such as urinary tract infections, gastro intestinal infections, skin and wound infections. The in vitro antibacterial (including anti-listerial and anti-vibrio) properties as well as the evaluation of the combination potentials of the plant extract with six front-line antibiotics were evaluated in this study using standard procedures. The in vitro anti-listerial properties of the crude aqueous and n-Hexane extract of the husk of Cocos nucifera were carried out against 37 Listeria isolates. Twenty-nine of the test organisms were susceptible to the aqueous extract while thirty were susceptible to the n-Hexane extract both at the screening concentration of 25 mg/ml. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.6 - 5.0 mg/ml. For the aqueous extract, average log reduction in viable cell count ranged between 0.32 Log10 and 4.8 Log10 CFU/ml after 8 hours interaction in 1 × MIC and 2 × MIC. For the n-Hexane extract, the log reduction ranged between 2.4 Log10 and 6.2 Log10 CFU/ml after 8 hours interaction in 1 × MIC and 2 × MIC. The time-kill characteristics of the two extracts suggest that at higher concentration (2 × MIC) and longer duration of interaction (8 hr), more bacteria were killed. In vitro anti-vibrio and antibacterial properties experiment revealed that of all the 45 vibrio and 25 bacteria strains that was tested, 37 were susceptible to the aqueous extract and 38 to the n-Hexane extract, while 17 were susceptible to the aqueous extract and 21 to the n-Hexane extract. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.3 - 5.0 mg/ml. viii The time kill studies revealed that for the aqueous extract, average log reduction in viable cell count in time kill assay ranged between 0.12 Log10 and 4.2 Log10 CFU/ml after 8 hr interaction at 1 × MIC and 2 × MIC. For the n-Hexane extract, the log reduction ranged between 0.56 Log10 and 6.4 Log10 CFU/ml after 8 hr interaction in 1 × MIC and 2 × MIC. In the test for the combination interactions, the checkerboard method revealed synergy of 67% and indifferent of 33%, while the time kill assay detected synergy in 72% and indifferent in 28% of the combinations tested. The synergy detected was not specific to any of the antibiotics or the Gram reaction of the bacteria, and no antagonism was detected. We conclude that the aqueous and n-Hexane extract of the husk of C. nucifera contains potential broad spectrum antibiotics resistance modulating compounds that could be relevant in the treatment of infections caused by these pathogens. In addition, the husk which is being discarded as agro waste will opens up a vista of opportunities for utilization for therapeutic purposes

  • Description: Governments around the world want to deliver better education, better health care, better pensions and better transportation services. They know that impatient electorates want to see change, and fast. But, the funds required to meet such expectations are enormous, particularly in the many developed economies where populations are aging and the public sector's productivity has not kept pace with that of the private sector. The need to get value for money from governments at all levels is therefore under the spotlight as never before. However, cost-cutting programmes that seek savings of 1 to 3% per year will not be sufficient and, in some cases, may even weaken the quality of service (Bhatia & Drew, 2006). One of the key innovative means to improve productivity, and do more with less, is through the implementation of lean initiatives. The purpose of this study is to conduct an 'Assessment of the status of lean implementation at selected SARS (South African Revenue Service) branch offices'. Literature review was conducted to investigate the origins of lean and how the service industry tapped from this philosophy, which was initially developed for the manufacturing sector. The lean philosophy has now been widely adopted in various service industries, from government agencies such as the South African Revenue Service to financial institutions such as ABSA bank, including the healthcare industry. The findings of the research indicated that even though the organisation has made a strategic decision to implement lean, this has not been entirely successful as there is a lack of understanding of lean among managers and team leaders. There are some pockets of excellence though. The researcher recommends that a comprehensive road map be developed to guide the organisation into a sustainable lean implementation.

  • Description: This treatise investigates the potential for law (including courts and tribunals) to intervene and act as a lever for the protection and advancement of the rights of the child including the right to basic education. The dissertation critically explores the debate on the educator‟s right to strike and fair labour practices and the child‟s right to education, by assessing the rights and liberties, which accrue to educators and the child (learners) in terms of existing law. The South African Constitution has made specific provision for the protection of the rights of children and the rights of educators and these rights are fundamental to the development of a society in transition. The vexed question that arises is whether these rights can co-exist in a society that has inherited a legacy of discrimination and inequality. The consequences of this legacy have resulted in the rights of educators competing with those of learners. The normalisation of the balance of these opposite rights is the challenge that lies ahead and this process will require intervention of all stakeholders rather than purely legislative intervention. This dissertation recommends a consensus-based approach, which is the most appropriate solution to balance the rights of educators with this of the child‟s right to education, as opposed to a declaration of the education sector as an essential service. It further proposes the establishment of a more structured and organised forum / institution and its sole purpose would be to deal with the individual or collective rights of educators that compete with the rights of learners.

  • Description: In plight of the country‟s high unemployment, poverty, and income inequalities, there is an urgent need to address these issues by converging toward entrepreneurship. World-wide, it is acknowledged by both government and academia that entrepreneurship soothes and remedies socio-economic ills. It creates employment, wealth, alleviates poverty, increases tax base, balances income disparities and accomplishes social stability. With the high youth (18-34 year age) unemployment looming at 73 percent and a low South African total entrepreneurship rate at 8.9 percent; this study attempts to investigate the barriers that hinder school leavers from engaging in entrepreneurship. The research investigates critical entrepreneurial factors including entrepreneurial character and behaviour, entrepreneurial knowledge and skills, managerial knowledge and skills, knowledge on legal aspects of a business, sourcing of finances, and entrepreneurial background and orientation. The primary objective was met through the investigation of the secondary objectives. This was accomplished through a questionnaire survey, composed with multiple choice questions and closed questions measured on a Likert scale. The questionnaire was constructed based on the literature reviewed from various sources including books, dissertations, journals, government reports, newspapers, magazines, internet, television and radio broadcasts (interviews and news). The study discovers that learners are inhibited by various factors from engaging into business venturing. The list of barriers identified was: A discouraging entrepreneurial background (heritage) – parents had low levels of education and were not entrepreneurial, Weak entrepreneurial character and behaviour, Lack of entrepreneurial exposure and work experience, Learners lack financial skills and computer skills, Families lack savings to financially support their business start-ups, Limited knowledge on the legal aspects regulating a business, Limited knowledge on sourcing finances (angel and venture capital investors).

Making use of prior information (available from the coefficients estimated on other data sets, or expert knowledge about the coefficients) a Bayesian approach is proposed to improve the credit scoring models. To achieve this, a data set is split into two sets, “old” data and “new” data. Priors are obtained from a model fitted on the “old” data. This model is assumed to be a scoring model used by a financial institution in the current location. The financial institution is then assumed to expand into a new economic location where there is limited data. The priors from the model on the “old” data are then combined in a Bayesian model with the “new” data to obtain a model which represents all the available information. The predictive performance of this Bayesian model is compared to a model which does not make use of any prior information. It is found that the use of relevant prior information improves the predictive performance when the size of the “new” data is small. As the size of the “new” data increases, the importance of including prior information decreases

  • Description: Umkhonto we Sizwe (MK) was a military organization dominated by black Africans. Although it is not generally associated with Indian South Africans, who form a minority in the country, there were Indian MK members. This thesis explores the way in which Indian MK members reconciled aspects of their ethnic identity with their membership of MK. It explores the experiences of two generations of members: those born between 1929 and 1944 and those born between 1960 and 1969. In particular it looks at whether they experienced tensions between their ethnic and political identities. It explores what set these Indian South Africans apart from the rest of the Indian South African community that did not join MK. It also looks at what significant differences there were between different generations of Indian MK members. The research results show that the first generation MK members believe that their MK activities were „the highest form of passive resistance‟. An explanation for this way of referring to their activities could be that this was a way of reconciling tensions between their ethnic and political identities. The first generation was also very critical of the Indian SA community. This could be because they still feel part of this community despite having a strong political consciousness that is different from most of the community. It was found that some of the features that set Indian MK members apart from other Indian South Africans were that they were not raised in very religious households and occupied a fairly low rather than „middle man‟ economic position. In addition, members of the first generation of MK members were raised in comparatively multi-racial areas. Both generations made the decision to join MK because of Indian role models. There were some marked differences between the two generations of MK veterans. Most notably, the younger did not see their activities as in line with passive resistance and they also displayed more ambivalence about their ethnic identities.

  • Description: This research has been directed at furthering the utilization of crude glycerol oversupply formed as a by-product from the biodiesel manufacturing process. Phosphorylation of hydroxyl groups is a synthetic route that was investigated for the conversion of glycerol into a glycerol-phosphate (GPE) ester mixture. The process investigated for the synthesis of a GPE product was based on phosphorylation reaction procedures that were previously reported in the literature. The reaction to convert glycerol into a GPE mixture has been thoroughly investigated and the hydrogen chloride gas formed as a reaction by-product has been optimized. The chemical properties of GPE have been studied and discussed together with a mass balance of the overall glycerol phosphorylation process. The phosphate groups contained in polyhydric phosphate molecules have a potential chelating effect on cations. There are several cations that may be chelated by the phosphate ester group of polyhydric phosphate molecules. These cations include ammonium (NH4+), Potassium (K+), Calcium (Ca2+) etc, which are essential as nutrients in plant fertilizer formulations. This research has investigated the use of a GPE synthesized from glycerol in the laboratory and the use thereof as a phosphorus containing base in the formulation and evaluation of Nitrogen, Phosphorus and Potassium (NPK) containing fertilizer solution, Ammonium-Potassium-Glycerol-Phosphate (APGP) fertilizer solution. The APGP fertilizer solution has further been evaluated by growing two week old tomato seedlings under controlled conditions. The performance of the APGP fertiliser solution has been evaluated using design of experiments by comparison with traditionally used liquidAmmonium-Potassium-Phosphate inorganic fertilizer. This fertilizer solution has been prepared in similar manner as APGP formulation with the difference between them being the source of phosphorus. The results have been evaluated using statistic analysis where a significant difference between the evaluated fertilizer formulations was found. The comparative study of these formulations was monitored by the observed plant weights. A blank treatment was used as a control to determine if a significant difference among these formulations was observed. Anova single factor and t-Test methods (Two-Samples assumed of equal variances) are statistical models that were applied to interpret the observed experimental data with respect to wet and dry weighed masses of tomato seedlings. These methods indicated a confirmed conclusion that there was a significant difference between APPO4 solution and APGP solution. The observed data have shown that the APPO4 solution provided significantly better fertigation performance than APGP solution. Consequently, further investigation has been conducted to determine the cause of the poorer performance of the APGP solution. The further study of the APGP fertilizer solution included nutrient stability testing, biological analysis and other observed physical changes of the APGP solution over time. Biological results have revealed the presence of a Fusarium fungus species that has grown and is suspended in APGP fertilizer solution. This microbe species has been observed to play a vital role in consuming fertilizer nutrients. In addition, the observed abnormal plant growth and nutrient decomposition of the APGP formulation has been proposed to be mostly a result of the pathogenicity of the fusarium fungi species that was suspended in the APGP solution. Further work has been proposed in which the effect of such biological contamination is eliminated through adequate sterilization procedures and the APGP formulation re-evaluated.

  • Description: Abstract Medicinal plants have been for long remedies for human diseases because they contain components of therapeutic value. The growing problem of antibiotic resistance by organisms demands the search for novel compounds from plant based sources. The present study was aimed at evaluating the bioactivity and phytochemical analysis of Hydnora africana on clinical and standard strains of Helicobacter pylori (PE 252C and ATCC 43526), Aeromonas hydrophila ATCC 35654, and Staphylococcus aureus NCT 6571 in an effort to identify potential sources of cheap starting materials for the synthesis of new drugs against these strains. Ethyl acetate, acetone, ethanol, methanol, and water crude extracts of H. africana were screened for activity against the test organisms using the agar well diffusion assay. The Minimum Inhibitory Concentration (MIC50) and Minimum Bactericidal Concentration (MBC) of the most potent extracts were determined by the microdilution method, followed by qualitative phytochemical analysis. Results were analyzed statistically by ANOVA one - way test. Different concentrations (200,100, 50mg/mL) of the methanol, acetone, ethanol and ethyl acetate extracts showed activity against S. aureus and A. hydrophila while for H. pylori, only methanol and ethyl acetate extracts were active; water showed no activity for all studied bacterial pathogens. Mean zone diameter of inhibition which ranged from 0-22mm were observed for all test bacterial pathogens and 14-17mm for ciprofloxacin. The activity of methanol and ethyl acetate extracts were statistically significant (P< 0.05) compared to all the other extracts. MIC50 and MBC ranged from 0.078 – 2.5mg/mL, 0.78-25mg/mL respectively for all tested bacterial pathogens. For ciprofloxacin, the MIC50 and MBC ranged from 0.00976 – 0.078mg/mL and 0.098– 0.78mg/mL respectively. There was no statistically significant difference between extracts (methanol, acetone, ethanol, ethyl acetate) and the control antibiotic (ciprofloxacin) (P> 0.05). Qualitative phytochemical analysis confirmed the presence of alkaloids, saponins, steroids, tannins and flavonoids in the methanol, acetone,ethanol and ethyl acetate extracts. The results demonstrate that H. africana may contain compounds with therapeutic potentials which can be lead molecules for semi-synthesis of new drugs.

  • Description: The transition from cycling to running has been identified as one of the key determinants of success in triathlon, as it has been suggested that the cycle may affect subsequent running efficiency such that running performance is significantly altered or reduced. It is also suggested that athletes more adapted to the transition itself, rather than purely running or cycling, may be more efficient during the post-cycle running bout. The current study sought to investigate the effects of prior cycling on subsequent selected biomechanical, physiological and perceptual responses of three different athlete groups. Subjects were selected on the basis of their sporting background, and were divided into three groups – triathletes, cyclists and runners. Experimentation required subjects to perform a seven minute treadmill running protocol at 15km.h⁻¹, during which biomechanical (EMG, Stride rate, Stride length, Vertical acceleration), physiological (HR, VO₂, EE) and perceptual (RPE) responses were recorded. After resting, subjects were required to perform a twenty minute stationary cycle at 70% of maximal aerobic power (previously determined), immediately followed by a second seven minute treadmill running protocol during which the same data were collected and compared to those collected during the first run. Biomechanical responses indicate that the cycle protocol had no effect on the muscle activity or vertical acceleration responses of any of the three subject groups, while the triathlete group significantly altered their gait responses in order to preserve running economy. The triathlete group was the least affected when considering the physiological responses, as running economy was preserved for this group. The runner and cyclist groups were significantly affected by the transition, as running economy decreased significantly for these groups. Perceptual responses indicate that athletes more experienced with the transition may find the transition from cycling to running to be easier than those inexperienced in this transition. It is apparent that a high intensity cycle protocol has limited statistical impact on selected biomechanical responses, while physiological and perceptual responses were altered, during a subsequent run, regardless of athlete type. That said, the ability of transition-trained athletes to transition comfortably between disciplines was highlighted, which may have important performance implications.
