  • Description: Over the years there has been an exceptional growth in electrical and electronic products. Technology improved consumer products have become a vital part of mankind’s daily living experiences and development. This has made a significant difference in the standard of living for many people (Okorhi et al., 2015). The same phenomenon has also made a major contribution to science and agricultural activities. However, the by-products belonging to electrical and electronic appliances and the dismantling processes have created huge challenges. The contents of these devices have brought along a visible threat to people and the environment. E-waste contains a multitude of elements which contain certain toxic substances. Exposure to these hazardous substances can be dangerous to humans and the environment (Rajput,2013). The inappropriate handling comes in the form of legal or illegal dumping, crude recycling, improper treatment and using incorrect disposalmethods. On the other hand, e-waste devices have the potential to augment lifestyles by recycling and reusing endof- life devices or extracting elements such as lead, gold, silver etc. (UNEP, 2007). E-waste has been growing rapidly world-wide and has become one of the fastest growing waste streams. This phenomenon has been fuelled by consumers purchasing multiple electrical and electronic products. The high obsolescence rates of these products lead to the dumping of these devices for newer products. The increasing market penetration through technology also receives a boost from social changes such as globalisation and urbanisation (Babu et al., 2007). The main aim of this study is to ascertain the relevance of e-waste management and its consequences in the Nelson Mandela Bay Metropole. World-wide, many countries have or are busy putting together policies and legislation to combat e-waste. South Africa has certain policies and legislation in place regarding hazardous substances. However, the policies and legislation are not specific enough when it comes to the collection, recycling and disposal of e-waste (Dittke, 2007). Against this background, the aim of this study was to investigate certain factors that influence households, when it comes to the management of household e-waste. These factors include the awareness and the participation of households in the management and disposal of electronic and electrical waste in the Nelson Mandela Bay Metropole. A theoretical framework was developed to address the above-mentioned challenges. Three suburbs in the NMBM were purposely selected to conduct this study. These suburbs fell into the lower, middle and high-income areas. The study used the quantitative research method and data was gathered by using questionnaires. A systematic random sampling method was applied to distribute the questionnaires. The data was analysed, and certain conclusions were made. Firstly, there is a wide range of e-waste being indiscriminately disposed of by householders. Secondly, findings indicated a low level of awareness regarding the environmental and harmful effects of e-waste when it comes to humans. Thirdly, the study also revealed that NMBM has no household e-waste management strategy in place. The study recommends the need for meaningful environmental education to uplift community awareness pertaining to e-waste management. Lastly, the NMBM needs to formulate by-laws and guidance policies when it comes to household e-waste disposal. These recommendations will help to preserve our world for future generations.

  • Description: In 1913 in South Africa the natives of land act during apartheid resulted to the separation of South Africa. South Africa was divided into two areas where they were black and white areas. This act had a rule that said the black people can only move out of their lands only if employed as labourers by the whites. The white population was one-fifth of the population and was given 92.5 percent of the land while the rest of the population were blacks and they were restricted to stay on the 7.5 percent of land. In the Eastern Cape, two homelands were created: the Transkei (in 1951) and the Ciskei (in 1961). In 1963 the Transkei became the first homeland to be granted the status of 'self-governing territory within the Republic of South Africa’, with the Ciskei following suit in 1972. The apartheid policies caused economic failure and corruption because very little economic and infrastructural development took place in the homelands. According to the ‘legacy perspective’: the former homelands are historically-determined structural poverty traps. The objective of the study is to describe the extent and change of economic function/role of Ngcobo town and linkages with its surrounding villages. Availability or convenient sampling and random sampling techniques were used to collect primary data from farmers and surrounding villages. Descriptive statistics was used to profile farmers as well as the participants in the surrounding villages. Descriptive statistics was used to describe the change in the economy of Ngcobo town and the change in the economy of the surrounding rural areas. Households in the former homelands devote a large share of their total expenditure to food and beverages, and yet it would appear that a relatively small share of this food originates from these same rural areas. The point of departure of this report is the observation that rural areas are diverse, whereby some areas within the former homeland areas in particular exhibit signs of dynamism which are not understandable in terms of the ‘legacy perspective’.

  • Description: South Africa is characterised by high levels of HIV infections and unwanted pregnancies, despite the vast amount of interventions aimed at combatting this issue. It becomes important to explore why these interventions are not actively achieving what they aim to. A major cause for concern is the increase in risky sexual behaviour in the adolescence and young adult (15-24 year) age group. In various cultures, women’s socialization has a direct impact on their ability to prioritize their sexual health. Steeped in patriarchal ideology, many South African cultures prioritise the power of masculinity over and above the femxle experience. Improved partner communication leads to decreased risky sexual behaviour, but it becomes tricky when the relationship is characterized by a gender power imbalance. This study is aimed at understanding South African femxle sexual health by focussing on 1) the extent to which the overarching traditional beliefs about femininity is related to their sexual self-efficacy. Furthermore, it is aimed at 2) the extent to which they engage in sexual activity and behaviour that would protect them from STIs and unwanted pregnancies. Research design is quantitative and include an online survey for femxle students between the ages of 18 and 24, enrolled at the Nelson Mandela University, South Africa. The data was analysed statistically, where after the research findings will be interpreted from the perspective of Feminist Psychological Theory.

  • Description: Small Medium and Micro Enterprises (SMMEs) are increasingly becoming an influential factor behind economic growth. On the other hand, knowledge management is credited with being critical to the success of modern business enterprises. Consequently, researchers have a growing interest in understanding knowledge management and its effects on various phenomena within an enterprise. Although SMMEs are tipped to be major providers of employment, innovations and economic growth, it is important that they be investigated in light of factors that influence their sustainability and growth. Notably there is evident lack of research exploring the relationship among absorptive capacity, knowledge management and innovation capabilities from a South African perspective as many of the related studies are concentrated in the developed world. The purpose of the study was to investigate the effects of knowledge management on innovation capabilities in SMMEs with focus on the Buffalo City Metropolitan Municipality. South African SMMEs are experiencing worrying failure rates, whilst on the other hand; knowledge management is credited with organisational success. This trend has presented an opportunity to test how knowledge management affects South African SMMEs innovation capabilities. Above this, the increasing value being attached to SMMEs in solving problems, such as unemployment and trade imbalance have attracted interest as a subject of research. A quantitative research approach was followed in carrying out this study. Descriptive and inferential statistics were performed to answer the research questions of the study. The respondents (n=280) were SMMEs representatives for SMMEs operating in the Buffalo City Metropolitan Municipality. Findings of the study revealed that absorptive capacity exerts positive a effect on the innovative capabilities of SMMEs the same way knowledge acquisition and knowledge sharing were found to have positive statistically significant on the innovation capabilities of SMMEs. The findings also show that knowledge sharing and knowledge acquisition exerts a positive effect on SMMEs innovative capabilities. Findings from the study could assist various practitioners directly or indirectly involved in business development to develop strategies that improve SMMEs growth and sustainability. These practitioners include strategic management researchers, policy makers, SMME owners, managers, and lecturers.

  • Description: Globally, the association between physical fitness, motor proficiency and scholastic achievement has been well researched. However, information concerning the effectiveness of integrated movement programmes in children from various socio-economic disparities, is less well studied. A lack of studies exists on the relationship between perceptual-motor development and scholastic performance in literacy and numeracy in children from low-middle income countries such as in sub-Saharan Africa. Thus, the need exists for educational movement programme implementation in developing countries based on studies of good methodological design, to allow early prevention, identification and rectification of apparent motor deficits in young children. Purpose (Aim): To investigate effects of an integrated movement programme in the classroom setting on motor proficiency, visual-motor integration and scholastic achievement of grade one learners between the ages of six- to nine-years-old in quintile five primary schools in Port Elizabeth. A quasi-experimental research design was used to evaluate the selected dependent variables at baseline assessment on 45 grade one learners from an experimental-and control group in quintile five schools in Port Elizabeth. There were two intervention periods that consisted of a pre-existing classroom-based integrated movement programme (NeuroNet) administered by an internationally accredited teacher to the experimental group. Each intervention period coincided with school terms three and four in 2017 and were a minimum of four weeks long. Pre-test and post-test assessments for all three dependent variables were done at the beginning and end of each term respectively. The learners participated in the integrated movement programme five days per week for 20-minute duration in the classroom. The main two standardised, reliable and valid test batteries used to measure motor proficiency and visual-motor integration were the Bruininks-Oseretsky Test of Motor Proficiency Brief Form (BOT-2 Brief Form) and the Beery-Buktenica Developmental Test of Visual-Motor Integration Full Form sixth edition (Beery VMI). The Beery VMI contained two sub-tests the Beery VMI Visual Perception Test (VMI-VP), and the Beery VMI Motor Coordination Test (VMI-MC), which measured the participants’ visual perception and motor coordination. Scholastic achievement was measured using four domains of the participants’ school reports: numeracy, reading, writing and total scholastic achievement scores. Purposive sampling was used to obtain participants from quintile five primary schools whose principals voluntarily provided consent to undertake the study. Data was collected by trained research assistants and the sole researcher. The Statistica for Windows (StatSoft Incorporated; 2014) software package was used for data analysis. Descriptive data analysis included the means (M) and standard deviations (SD) as measures of central tendency and distribution. Independent t-tests determined between-group differences and the level of significance was set at p<0.05. The magnitude (effect size) of pre-post-intervention differences for both groups was calculated for all variables as Cohen’s d statistic. Subsequent interpretation categories were d<0.20 (insignificant effect), 0.20≤d<0.50 (small effect), 0.50≤d<0.80 (medium effect) and d≥0.80 (large effect) (Gravetter & Wallnau, 2009). The experimental group had statistically significant (p<0.05) higher initial mean values for motor proficiency, visual perception, the reading, writing and total scholastic achievement domains. Motor proficiency showed a mean increase of 10.62±13.97 (24% improvement) in the experimental group compared to a mean increase of 9.63±13.26 (8% improvement) in the control group. A significant final mean between-group difference in motor proficiency was found post-intervention (Diff=16.70, t(43)=3.70, p=0.001; Cohen’s d=1.11: large effect size). Visual-motor integration showed a mean decrease of 5.38±14.34 in the experimental group and a decrease of 8.88±15.39 in the control group. No apparent between-group significant difference occurred for visual-motor integration. Visual perception scores indicated a mean increase of 11.82±18.81 in the experimental group and a mean increase of 15.71±30.03 in the control group. A statistically significant mean between-group difference in visual perception post-intervention was seen (Diff=26.40, t(43) =3.95, p<0.0005; Cohen’s d=1.18: large effect size). Motor coordination showed a mean increase of 20.00±18.45 in the experimental group and decrease of 1.50±23.74 in the control group over the intervention period (Diff=21.50, t(43)=3.36, p=0.002; Cohen’s d=1.00: large effect size). There was a significant between-group mean motor coordination difference post intervention (Diff=19.59, t(43)=2.96, p=0.005; Cohen’s d=0.88: large effect size). The experimental group showed significantly higher mean reading scores pre- 5.67±0.80 and post-intervention 5.43±0.93 compared to the control group pre- 4.13±0.74 and post-intervention 4.63±0.88. Significant between-group differences in reading scores pre- (Diff=1.54, t(43)=6.73, p<0.0005; Cohen’s d=2.01: large effect size) and post-intervention (Diff=0.80, t(43)=2.99, p=0.005; Cohen’s d=0.89: large effect size) were also evident. The experimental group also showed significantly higher mean writing scores pre- 5.62±0.74 and post-intervention 5.05±0.86 compared to the control group pre- 3.83±0.96 and post-intervention 4.21±1.28. A significant between-group difference in writing scores pre- intervention (Diff=1.79, t(43)=6.90, p<0.0005; Cohen’s d=2.06: large effect size) was evident. Total scholastic achievement scores showed an initial significant difference between the experimental- and control group (Diff=1.26, t(43)=6.42, p<0.0005; Cohen’s d=1.92: large effect size). Positive practical significance |r|≥0.300 at (p<0.05) was found between visual-motor integration and reading |r|=0.350; visual perception and writing |r|=0.336; motor coordination and writing |r|=0.318; visual-motor integration and total scholastic achievement |r|=0.330 in the experimental group. In the control group negative practical significance |r|≥0.300 at (p<0.05) was found between visual perception and reading |r|=-0.304, whereas positive practical significance was found between visual perception and writing |r|=0.319; motor coordination and writing |r|=0.340; motor coordination and numeracy |r|=0.378; and motor coordination and total scholastic achievement |r|=0.378 at (p<0.05). The integrated movement programme had significantly positive effects on motor proficiency, visual perception and motor coordination. Motor proficiency had no significant correlation to scholastic achievement domains post-intervention, whereas visual-motor integration significantly correlated to reading and total scholastic achievement; visual perception correlated significantly to writing and negatively to reading; and motor coordination correlated significantly to writing, numeracy and total scholastic achievement. Future longitudinal research incorporating a larger range and scope is needed to fully evaluate the effectiveness of integrated movement programmes on motor proficiency, visual-motor integration and scholastic achievement.

  • Description: Although it is increasingly accepted that ocean acidification poses a considerable threat to marine organisms, little is known about the likely response of fishes to this phenomenon. While initial research concluded that adult fishes may be tolerant to changes predicted in the next 300 years, the response of early life stages to end-of-century CO2 levels (~ 1100 µatm according to the IPCC RCP 8.5) remains unclear. To date, literature on the early growth and survival of fishes has yielded conflicting results, suggesting that vulnerability may be species dependant. The paucity of ocean acidification research on fishes is particularly evident when one considers larval skeletogenesis, with no robust studies on its impacts on bone and cartilage development. This study addresses the early life embryogenesis, hatching success, growth, skeletogenesis and survival of an estuarine-dependant species. Dusky kob (Argyrosomus japonicus) were reared in a control (pCO2 = 327.50 ± 80.07 qatm at pH 8.15), intermediate (pCO2 477.40 ± 59.46 qatm at pH 8.03) and high pCO2 treatment (pCO2 910.20 ± 136.45 qatm at pH 7.78) from egg to 29 days post-hatch (dph). Sixty individuals from each treatment were sacrificed at the egg stage and at 2, 6, 13, 18, 21 and 26 dph, measured and stained using an acid-free double- staining solution to prevent the deterioration of calcified matrices in fragile larval skeletons. The proportion of bone and cartilage was quantified at each stage using a novel pixel-counting method. Growth and skeletal development were identical between treatments until the onset of metamorphosis (21 dph). However, from the metamorphosis stage, the growth and skeletal development rate was significantly faster in the intermediate treatment and significantly slower in the high treatment when compared to the control treatment. By 26 dph, A. japonicus reared in high pCO2 were, on average, 47.2% smaller than the control treatment, and the relative proportion of bone in the body was 45.3% lower in the high pCO2 treatment when compared with the control. In addition, none of the fish in the high pCO2 treatment survived after 26 dph. It appears that the combination of the increased energy requirements during metamorphosis and the increased energy cost associated with acid-base regulation may account for reduced growth, skeletogenesis and poor survival in high pCO2. Regardless of the driver, the results of this study suggest that the pCO2 levels predicted for the end of the century may have negative effects on the growth, skeletal development, and survival during metamorphosis.

  • Description: The study set out to establish the effects of CBO’s programmes on poverty eradication in Dutywa Mbhashe Local Municipality, Eastern Cape Province. Poverty is rife in rural areas of Dutywa and community. Community members suffer from both absolute to relative poverty. Community organizations, especially in developing countries, have strengthened the view that these bottom-up organizations are more effective in addressing local needs than larger charitable organizations. This study was done through the reviewing of the implementation of early childhood development programmes, family preservation programmes, victim Empowerment programmes, home community based care programmes (HIV/AIDS), as well as care and support to older person’s programmes by community based organizations with the aim of alleviating poverty. The selection of the district and CBOs was done purposively and data was gathered through focus group discussions, structured and unstructured interviews. Purposive sampling technique was also used in selecting participants who took part in the study. Data analysis was carried out through charts, frequency tables and percentages. Qualitative analysis was carried out through establishing the emerging themes and comparing responses in order to check the validity of the data collected. Quantitative analysis was done through the application of the Statistical Package for Social Science (S.P.S.S). Two objectives were quantitatively analysed and two objectives were qualitatively analysed. The findings revealed that the programmes rendered by the CBOs were effective in the fight against poverty in Mbhashe, Dutywa and it was recommended that there should be an effective monitoring and evaluation of community development programmes and identification of sources of support most especially local sources. It was also recommended that community programme should be aligned with the community cultures.

  • Description: Soccer is regarded as one of the most popular sports in the world, and involves explosive physical actions such as kicking, jumping, rapid changes of direction and sprinting. These attributes would suggest that strength, power, and agility may play an important role in soccer performance. Elastic band resistance training serves to increase strength, power, speed, balance, coordination and agility However, there is little published research available on the use and effectiveness of elastic-band resistance training as a tool for improvement in muscular strength and power of soccer players. Purpose: To determine the effect of elastic-band resistance training on strength, speed, agility and vertical jump height of university soccer players. The present study used a pre-test post-test experimental study design. The participants comprised of 15 Eastern Cape male soccer players, currently affiliated with the Nelson Mandela University soccer teams. Participants were randomly allocated into one of two groups: a conventional resistance training group, and an elastic band tension resistance training group. Stratified random sampling was used to ensure an even distribution of the performance levels and training experience between the participants. Analysis implemented used Microsoft Excel® and the latest version of Statistica for the purpose of descriptive and inferential statistics. Additionally, Pearson correlation coefficient and coefficient of determination were used to identify statistical correlations between variables of interest. Inferential statistics were applied using analysis of covariance (ANCOVA), and in the case of significant findings, the Scheffé post-hoc test was utilized for comparisons. Independent t-tests indicated significant between-group differences. The alpha level was set at 0.05. Results: The main findings were that elastic band resistance training would appear to be a superior method to conventional resistance training given that: This method was able to produce greater results in improving maximal vertical jump when compared to free weight resistance training (ANCOVA, F(1,25)=9.1135, p=0.00577), produced faster 40m iv sprint times in comparison to free weight resistance training (ANCOVA, F(1, 25)=4.534, p=0.043), and produced significant improvements in one repetition maximum performance in the squat (ANCOVA, F(1, 25)=5.454, p=0.028). Based on the results of this study, it would appear that both the elastic band resistance training and free weight resistance training were effective in increasing performance in both the one repetition maximum deadlift and agility tests, with no significant difference between the two methods (ANCOVA, F(1, 25) =0.328, p=0.572), ANCOVA, F(1, 25)=3.597, p=0.069 respectively). Elastic band resistance training may be an effective alternative training methodology to improve performance variables in university soccer players. However, further research may be needed to clearly define the role of combined elastic band resistance training in the periodization of soccer training in a competitive season.

  • Description: The purpose of this study was to do a comparative investigation on the acid- and heat catalysed polymerisation and resinification of furfuryl alcohol and the effects of these polymerisation conditions on the mechanism, morphology, molecular weight and thermal properties of the polyfurfuryl alcohol resins. The formation of furfuryl alcohol polymers was confirmed using size exclusion chromatography (SEC); the synthesised polymer resins were investigated using Fourier transform infrared spectroscopy (FTIR,), scanning electron microscopy (SEM) and Thermogravimetric analysis (TGA). The effects of polymerisation conditions on the mechanism of polyfurfuryl alcohol polymerisation was a major focus of this study. The obtained results confirm that the surface topology, mechanism of polymerisation, thermal behaviour and molecular weights of polyfurfuryl alcohol polymer resins are dependent on the polymerisation condition. The acid and heat catalysed polyfurfuryl alcohol resin polymers presented interesting and promising results.

  • Description: This study evaluated the carcass and meat quality traits of spent laying hens as influenced by production systems (conventional cages and free range) and the inclusion/exclusion of canola meal in their diets. A total of 30 free range and 60 battery cage reared Lohmann Brown-Elite spent laying hens were obtained from a commercial egg producer. The 30 free range hens (53 weeks of age) and 30 of the caged hens (40 weeks of age) were fed a conventional diet, while the remaining 30 caged hens (48 weeks of age) were fed a diet supplemented with canola meal (20 percent). Carcass, portion and organ weights were determined. Physical attributes and proximate composition were analyzed for, with additional fatty acids and sensory profiles being determined for the effects of canola meal inclusion in the diet. Caged hens had heavier (P ≤ 0.05) warm and cold carcasses, thigh, wing and feet compared to free range hens. The percentages of the breast (26.1 ± 0.51 vs. 28.3 ± 0.28), drum, breast bones, breast thaw and cooking losses and thigh cooking loss were lower (P ≤ 0.05) for caged hens than for free range hens. Free range hens had heavier (P ≤ 0.05) gizzards (33.9 ± 1.04 vs. 30.5 ± 0.73) and bones and a lower (P ≤ 0.05) breast meat percentage (47.3 ± 0.94 vs. 51.7 ± 1.35). Meat redness (a*) (0.54 ± 0.222 vs. 1.40 ± 0.135) and hue angle value, skin redness (a*), breast and thigh, Warner-Bratzler shear force (WBSF) values (breast: 12.37 ± 0.411 vs. 17.10 ± 0.751, thigh: 29.68 ± 0.306 vs. 39.75 ± 0.826), breast moisture and thigh ash content were lower (P ≤ 0.05) for caged hens than free range hens. Caged hens had higher (P ≤ 0.05) thigh thaw loss and breast ash content than free range hens. Canola-fed hens had higher (P ≤ 0.05) drum percentages, breast bone weights and percentages, with lower (P ≤ 0.05) thigh and breast meat percentages. Canola-fed hens had lower (P ≤ 0.05) thaw losses, skin yellowness (b*) and Chroma values, breast fat content with higher cooking losses, skin redness (a*) and hue angle value, as well as breast WBSF (12.37 ± 0.411 vs. 15.43 ± 0.600). Palmitic acid, stearic acid, heneicosanoic acid acid, palmitoleic acid, saturated fatty acids (SFA) (34.0 ± 0.56 vs. 38.7 ± 0.71), n-6:n-3 polyunsaturated fatty acids (PUFA) ratio (5.5 ± 0.13 vs. 7.2 ± 0.28), atherogenic index (IA), thrombogenic index (IT), delta-5 desaturase (D5D, elongase index and thiosterase index were lower (P ≤ 0.05) for canola-fed hen breast meat. Breast meat from conventionally fed hens had lower (P ≤ 0.05) myristic acid, lignoceric acid, nervonic acid, alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), PUFA:SFA ratio (0.7 ± 0.05 vs. 0.9 ± 0.02), n-3 PUFA (3.4 ± 0.31 vs. 5.1 ± 0.17), hypocholesterolemic:Hypercholesterolaemic (h/H), stearoyl-CoA desaturase 16 (SCD16) and stearoyl-CoA desaturase 18 (SCD18). The breast meat from conventionally fed hens had lower (P ≤ 0.05) metallic flavor than that from canola-fed hens. Strong positive correlations were observed for overall aroma with chicken (r = 0.965, P < 0.001) and brothy aroma (r = 0.827, P < 0.001); overall aroma with overall flavor (r = 0.680, P < 0.001), chicken flavor (r = 0.668, P < 0.001) and brothy flavor (r = 0.548, P = 0.006); initial juiciness with sustained juiciness (r = 0.771, P < 0.001) and tenderness (r = 0.537, P = 0.007); sustained juiciness with tenderness (r = 0.790, P < 0.001) and chewiness with residue (r = 0.783, P < 0.001). Whilst strong negative correlations were observed for: sustained juiciness with chewiness (r = -0.655, P = 0.001) and residue (r = 0.783, P < 0.001) and for tenderness with chewiness (r = 0.845, P < 0.001) and residue (r = -0.855, P < 0.001). Results of this study highlight that a free range production system when compared to a conventional cage system increased undesirable carcass and physical meat traits of spent laying hens. On the other hand, canola meal inclusion incorporates beneficial health aspects without affecting the sensory profile of meat derived from spent laying hens, both groups of hens being reared in battery cage system. Spent laying hen breasts can be consumed as a functional food (especially canolafed) since the fat content and composition was observed to be close to that which is recommended for a healthy diet.

  • Description: Over the years, the lead acid battery’s performance in modern vehicles has improved considerably to adapt to the new demands of vehicle electronics and start-stop applications. Although vehicles are valuable for commuting, their high volume of usage has resulted in an increase of fuel prices and emitted carbon dioxide (CO2). Due to the drastic global warming concerns, vehicle manufactures have been pressured into developing a variety of hybrid electric vehicles (HEV) that would reduce their fuel consumption and thereby reduced CO2 emission. The HEVs construction requires the implementation of advanced battery systems that operate under high rate partial state of charge (HRPSoC) conditions. During battery’s discharge, the Pb contained on the negative plate is oxidised to insulating PbSO4 crystals. When the battery is charged, the PbSO4 is reduced back to Pb. With prolonged use at HRPSoC, the battery undergoes an irreversible process wherein small PbSO4 crystallites dissolve and precipitate into large passivating PbSO4 crystals that accumulate as a dense layer on the surface of the negative plate. This layer restricts the diffusion of the H2SO4 electrolyte into the reaction sites for further reactions, resulting in the battery to fail prematurely. Research has shown that the inclusion of appropriate carbon materials on the negative active material (NAM) improves the performance of the batteries in HRPSoC cycling. This study looked at the making of some of the carbon-based additives by using relatively cheap materials such as polyvinyl alcohol (PVA) polymer with a sucrose blend in ratios of 75:25, 50:50 and 25:75, respectively. The blended materials were electrospun into PVA/Sucrose nanofibers. These were further stabilised by iodine and carbonised at 500 °C in a tube furnace. The properties of the carbon fibres were investigated by a number of analytical techniques such as TGA, DSC, XRD, BET, FTIR and SEM. The obtained carbon fibre surfaces were further electroplated with Pb in order to investigate the chemical bonding, the relationship between the carbon-based material interface and the Pb was investigated by SEM and CV techniques. The results of the study demonstrated that the varied ratios of the PVA/Sucrose nanofibers influenced the differences in their respective chemical and physical properties. Thermal analysis demonstrated that at approximately 500 °C, the final residue of the PVA/Sucrose nanofibers decreased as the sucrose content decreased. iii Carbonisation of the nanofibers was confirmed by the structural changes corresponding to the disappearance of the major bonds of PVA and sucrose materials, as well as by the appearance of C=C stretches. Carbonisation was also confirmed by the XRD diffractogram that demonstrated two broad amorphous peaks that corresponded to the planes of the graphite structure. The broadness of the peaks confirmed the amorphous nature of the carbon fibres. The morphological studies demonstrated that upon blending PVA with increasing quantities of sucrose, the uniformity of the fibres was altered into beaded fibrous structures with large diameters due to the increased viscosity of the electrospinning solution. The behaviour of the Pb deposits on the carbon surfaces was influenced by the high quantity of PVA present on the blend and the fibrous structure of the carbonised material. The Pb had high affinity towards the fibrous carbon derived from 75:25 as it deposited widely across the surface. Whereas, the absence of Pb deposits on the surface of the carbon derived from the 25:75 ratio was an indication that the high sucrose content and the bulky non-fibrous structure hindered the electrodeposition. The electrochemical study findings demonstrated that the bare Pb electrode had two distinct current peaks corresponding to the anodic (discharge) and cathodic (charge) reactions of Pb/PbSO4. Upon the inclusion of the electrospun carbon materials on the Pb electrode, the intensities of the anodic and cathodic peaks were reduced. Implying that none of the carbon materials enhanced the electrochemical redox reactions of the Pb/PbSO4 couple in the H2SO4 electrolyte.

  • Description: Ideally, every employee is required to retire at some stage in life. Some retire at a relatively early age, whilst others work for as long as is possible. The generally accepted retirement ages are 55, 60 or 65, but vary from company to company as stipulated in the specific company's provident or pension fund rules or policy. Once retired, an individual would rely on social insurance as a source of income in the form of pension or a provident fund. Social insurance, in this regard, refers to the earned benefits of employees and is often linked to formal employment. South Africa, as a middle-income developing country, has incorporated such elements into its social security system. The main aim of a pension or provident fund is to provide benefits for its members when they retire from employment, retrenched, unable to work due to illness and for family in the case a member dies while still working. These forms of social security are key to people’s survival and are referred to as safety nets. benefits. Participation on a voluntary basis by the self-employed is allowed but the take-up has been low Employees’ pension and provident rights under a pension or provident scheme do not arise only under the trusts of the scheme but also as contractual terms of the employment relationship between the employer and its employees. This often takes effect on the date of taking up employment, or on entering into an agreement with the employer. Employment law covers all rights and obligations within the employee employer relationship and covers a range of legal issues such as discrimination, wrongful termination, wages and taxation. Many of these issues are governed by the applicable law. Although the South African retirement fund system is in many respects financially sound and well regulated, several individuals still reach their retirement age with inadequate savings. This occurs for several reasons. For many people, during their working life, the build-up of savings is disrupted, or the costs associated with retirement fund provisioning are relatively high. This problem is not only grave for some workers in the formal sector, but largely for those in the rapidly increasing informal sector. Majority of people still lack effective access to an affordable retirement funding vehicle, for the most part, are completely excluded from social protection schemes, social insurance schemes. The South African retirement fund industry has been heavily influenced by a racially divided past and the parallel existence of developed and emerging components of the economy. In the past, racially discriminatory exclusion from the pension fund or provident fund membership was prevalent. In many cases it was indirect discrimination based on job categorisation, such as the distinction between weekly paid and monthly paid staff. Where the staff complement was racially stratified, people were excluded from membership on the grounds of race. Discrimination in the workplace can deny individuals opportunities and thereby deprive society of what those individuals can and could contribute. This has unfortunately been the case in South Africa’s history, the administration of pension and provident funds being one of many examples.

  • Description: Fire and herbivory are both major drivers in grassland ecosystems throughout the world. Although these two driving forces act independently from one another the relationship between fire and herbivory may be more significant than either acting on their own. Heterogeneity within the landscape as a result of fire results in herbivores having to adapt their behaviour in space and time. My research focussed on 1) characterising the fire regime on Mkambati Nature Reserve (hereafter Mkambati) and 2) determining the foraging choices and energy maximisation principles displayed by herbivores in relation to the biomass of vegetation and post fire vegetation age. Fire regimes were characterised between 2007-2016 in the low nutrient coastal grasslands of Mkambati in terms of fire season, seasonality of fire-prone weather conditions, fire return interval (FRI) and influence of poaching-related ignitions. Based on these results I then assessed foraging choices in terms of energy maximisation of four large herbivore species. I explored what energy maximisation strategy was employed, i.e. maximisation of daily digestible energy (DDE) (recently burnt low biomass vegetation) or instantaneous digestible energy (IDE) (older high biomass vegetation), by herbivore species with different morpho-physiological traits. Common reedbuck (Redunca arundinum), red hartebeest (Alcelaphus buselaphus subsp. caama), zebra (Equus quagga) and eland (Tragelaphus oryx subsp. oryx) were fitted with GPS satellite tracking collars, and hourly GPS locations (observed) were taken between 2008 and 2016. Using mixed effects models, I compared observed and an associated set of random locations to determine the energy maximisation strategy employed by each species. Our results indicated that fires were concentrated in winter when monthly fire danger weather (FDI) was highest. The mean FRI at Mkambati was <3 years, but varied according to vegetation type, and whether censoring (for open ended FRIs) was applied to estimate mean FRIs. Poachers, with the intention of attracting ungulates, are an important source of ignition at Mkambati. Accordingly FRIs were shorter (approximately 2 years) in areas within 3 km of likely poacher entry points. Although all fires recorded at Mkambati during the study period were of anthropogenic origin, mean FRI still fell within the natural range reported for interior grasslands in South Africa. Based on these findings, underpinned by the fire regime information, I showed that red hartebeest and zebra maximised DDE inside and outside of fire seasons and frequently foraged in low biomass recently burnt grasslands. Eland generally favoured areas where they could maximise IDE outside of the fire season, however during the fire season they switched strategy to maximise DDE. Reedbuck did not maximise IDE or DDE at the same scale (patch scale) as the other species, but at a landscape (broader) scale they maximised both IDE and DDE. Through this research I have shown how regular fire affects the foraging and energy maximisation behaviour of large African herbivores and how morpho-physiological traits affect these decisions. In response to these results I recommend that the management of Mkambati implement a focused monitoring program comparing the frequently and less frequently burnt areas of the reserve in order to understand the complex effects of anthropogenic fire and its subsequent effects on the biota of Mkambati.

  • Description: This study explores how small-scale farmers in Nyanga, Zimbabwe engage with the media as a knowledge resource for achieving agricultural productivity, particularly in context of climate change. The study is contextualised by means of a literature review that maps out the history of agricultural productivity in Zimbabwe. It is argued that this history has been shaped by changes in both socio-economic context and climatic conditions. Both kinds of change impact on the degree to which small-scale farmers have access to knowledge that is of relevance to agricultural productivity. The study then examines the Zimbabwean media landscape, focusing on how history has shaped the way in which different media define their social purpose. This examination draws on Hallin and Mancini‟s „models‟ of media systems as well as Christian et al‟s traditions of media practice. It is concluded that, due to the high level of conflict that has characterised Zimbabwean history, aspects of both the polarised pluralist and democratic corporatist models are present in its media landscape. The collaborative, monitorial and radical approaches to media also exist in contestation with each other. Indeed, the media is characterised by profound contestation around the conceptualisation of social purpose. Furthermore, international media is of particular significance as a resource of knowledge within the local media landscape. The empirical component of the study explores the implications for the extent to which media are likely to serve as valuable knowledge resources for small-scale farmers. This exploration is pursued by means of a case study of the experiences of three farmers in Nyanga who were granted farms as part of the government‟s land-reform programme. In context of episodic biographical interviews, the participants share their experience of becoming farmers and of managing their farms. Attention is paid to the challenges they face with regards to producing successful crops, both in context of socio-economic and climatic conditions. The study looks at the way in which participants draw on the media as a knowledge resource to help them overcome these challenges. The participants understand international media to be a more credible knowledge resource, but also refer to the need for local media which can provides them with knowledge of local relevance. In this context they identify an absence of collaborative, developmental media that engages with the unique challenges that they face in producing crops. It is concluded that the value of media for the farmers of Nyanga as a knowledge resource for making sense of climate change would only be achieved through the establishment of locally produced, participatory media that foregrounds the use of indigenous language.

  • Description: Mayo (2016, p. 88) states that many researchers agree that investing in employee engagement has guaranteed great returns; the question for organisations are whether these returns will be linear or exponential for them. A new breed of company emerged called the “exponential organisation” which leverage accelerating technologies to achieve an unheard-of business model that shows exponential growth. However, this technology is still created, maintained and reinvented by employees. Therefore, the premise is that highly engaged employees are one of the key factors that fuel exponential organisations, and this was under investigation in this research study. Employee engagement has been extensively researched yet only a few organisations can claim the majority of their employees are highly engaged. The topic of employee engagement within exponential organisations, however, has barely been covered by scholars or practitioners. Subsequently, given that it is a new organisational phenomenon, little academic or practitioner’s research could be found. For this reason, the main purpose of this study was to find key drivers of employee engagement within exponential organisations to develop a theoretical framework and hypotheses which could be statistically tested. The outcomes could assist in enhancing employee engagement within exponential organisations, thereby achieving greater business success. An online survey questionnaire was used to gather empirical data within a financial technology exponential organisation. The sample consisted of 40 fulltime employees working in Australia, China and South Africa of which most were between the ages of 35 to 44 years old and have been with the organisation for less than two years. The results showed that organisational management and employee autonomy were found to have a direct positive relationship with the concept of employee engagement and is found to be key drivers of employee engagement within exponential organisations.

  • Description: In terms of the Health Professions Act (Act 56 of 1974), Environmental Health graduates are required to conduct a year of Community Service before they are allowed to register as independent Environmental Health Practitioners at the Health Professions Council of South Africa. The main purpose of Community Service by these graduates is to assist Environmental Health Practitioners in the execution of their daily tasks, thereby contributing to more effective service delivery, especially to the disadvantaged communities, within the sphere of government where they are deployed. Several studies have been conducted in an effort to identify problem areas in other health care professions during the Community Service year, but no such study could be found on Environmental Health. The aim of this study was to do the same for the Environmental Health profession in South Africa, by focusing on problems and challenges during Community Service placement, specifically the 2013 to 2016 intakes of Community Service practitioners in the Eastern Cape Province and the administrators responsible for the program at national, provincial and municipal spheres of government. The study employed both quantitative and qualitative research designs (mixed method) and was by nature explorative, descriptive and contextual. Two populations were involved; namely, twenty four Environmental Health graduates who completed their Community Service during 2013 to 2016 within the Eastern Cape Province, and ten Environmental Health Practitioners who were responsible for the administration of the Community Service program at the provincial and municipal spheres of government during the same period. A purposive sample was drawn from each population. Qualitative data was collected by means of interviews and quantitative data through questionnaires. Qualitative data was analysed using Tech’s method of data analysis and quantitative data was statistically analysed. The results of the study revealed that the Eastern Cape Department of Health needs to review the Community Service program for Environmental Health graduates and further initiate resolutions in terms of the identified problems, such as maladministration of Community Service which related to the lack of consistency of communication during the organisation of the Community Service program; declined/decreasing number of Environmental Health Community Service posts in the Eastern Cape Province which led to a shortage of human resources; Inadequate provision of material resources for Community Service; lack of induction training and inconsistent supervision of Environmental Health Community Service practitioners; and lack of evaluation of the success of the Environmental Health Community Service program. The study findings suggest important inequalities and non-compliances which should deserve urgent attention. Based on the challenges that have been identified regarding the organisation and implementation of the Community Service program, this study concludes by presenting recommendations for the improvement of the Community Service program in the Environmental Health profession.

  • Description: South Africa is a semi-arid country and thus depends on sound management of its water resources. Wetlands, despite their importance to water resource storage and water quality, among their other ecological and social significance, remain the most threatened of South Africa’s ecosystems. One of their greatest threats is encroachment by urbanisation. This occurs because wetlands, and especially ephemeral urban periphery wetlands, are overlooked. This study’s main objective was to determine the water quality and health of the wetlands adjacent to the newly established Bay West development on the western urban periphery of Nelson Mandela Bay. Wetlands are difficult to access and it is time-consuming to assess them. Remote sensing, however, overcomes this challenge and is cost-effective and time-considerate. It was the aim of this study to assess the health of the peri-urban wetlands on the Bay West periphery in order to formulate an appropriate environmental management plan, and remote sensing was tested as an effective method for wetland health management. It was found that the wetlands closer to the urban residential area (Sherwood suburb) were far more impacted than the wetlands nearer to Bay West Mall. Wetlands Six to Eight were higher in all parameters of pH, total dissolved solutes (TDS), salinity, conductivity and chlorophyll a concentration than Wetlands One to Five located further away from the urban area. A correlation with distance away from the urban area found a strong inverse relationship with between distance and the water quality factor, yielding a correlation coefficient of (<-0.7) in 2017 and (<-0.9) in 2018 with regard to TDS, salinity and conductivity. This, therefore, suggests that the wetlands’ health deteriorates towards the urban area. TDS, salinity, pH and conductivity correlate highly with chlorophyll a concentration at (>0.70). There was significant difference in pH in the year 2017 between the Bay West wetlands and the reference wetland (p<0.05; df=19; f= 3.56; n=3) and in 2018 (p<0.01; df=22; f= 8.90; n=3). No significant difference was found between the wetlands for dissolved oxygen. TDS between the wetlands was found to be significantly different in the year 2017 (p<0.01; df=23; f= 44.16; n=3) and 2018 (p<0.05; df=22; f=2.62; n=3), where conductivity and salinity returned the same p value for 2017 and 2018 as TDS respectively. There was a significant difference in chlorophyll a between the Bay West wetlands in 2017 (p<0.05; df=20; f=3.29; n=3) and Wetland Seven measured eutrophic at 22.45 mg/L-1. Remote sensing red band values and the field sample absorption values were highly correlated at R2= 0.5. Chlorophyll a content of wetland water correlated with NDVI data at R2= 0.6. Thus, remote sensing proved to be a successful estimator for wetlands health analysis and a proxy for wetland management. These results yielded an environmental management plan where monitoring water quality via chlorophyll a indicated health levels of the wetlands via trophic state.

  • Description: Municipalities have recently been in the media for the wrong reasons with certain allegations being levelled against these institutions. The allegations range from lack of service delivery, corruption and lack of good governance. This has resulted in communities showing frustrations through protests that result in the destruction of the existing infrastructure and, in some areas, boycotts towards payments of rates and services. The study seeks to establish the reasons that lead to ratepayers and communities not paying for rates and services. In the process of establishing the above, it seeks to come up with suggestions and solutions that can be implemented by municipalities to ensure that the ‘going concern’ is addressed. To achieve the above purpose a literature review was conducted on available sources of information looking at financial sustainability, the role of municipalities, powers and functions of municipalities and how these institutions are funded. The study also looked at literature regarding the strategies to increase revenue and improve debt collection. The study used Amahlathi Local Municipality as a case study where a sample was selected from the population. Questionnaires were developed and distributed to the sample and responses were received to the tune of 203 respondents. Questionnaires were both qualitative and quantitative as they had both open-ended and closed questions. Quantitative questionnaires were distributed to the community and the qualitative questionnaires were distributed for expert opinion. Analysis was done against the research questions to establish if there were any links to the literature and the findings of the study. The study found that communities are fed up with unsustainable or a lack of service delivery that the municipality is providing. This has been linked to some information gaps between the councillors and the community in terms of municipal programmes. More needs to be done in terms of ensuring that ward meetings are held on a regular basis so as to improve communication. There is also an observation of a ‘culture of non-payment’ emanating from political canvassing during voting periods which negatively affects the cash flows of the municipality and that public representatives need to champion debt collection endeavours.

  • Description: Globally there is a shortage of talent with organisations facing the challenge of attracting, engaging and retaining top talent. It has therefore become a priority for any organisation to ensure, that the offer made to attract talent, extends beyond a salary. The Employee Value Proposition (EVP) is a strategic tool that could be used to ensure that the offer made to employees is indeed an offer of value, considering both extrinsic and intrinsic attributes; therefore, ensuring the attraction, engagement and retention of talent. All organisations have an EVP, whether documented or not; however, the effectiveness thereof should be questioned. This was the aim of this study, namely, to assess whether a gap exists between the espoused and actual employee value proposition at the SPAR Group – Eastern Cape (SPAR EC). The study used an existing questionnaire to collect data from a sample of 150 respondents. The questionnaire was adapted to align to the company and industry studied and aimed to answer the following questions: To what extent did employees expect to find, both intrinsic and extrinsic EVP characteristics in the company? How important were these intrinsic and extrinsic EVP characteristics to attract employees to the organisation? In addition, to what extent did employees experience the expected intrinsic and extrinsic EVP characteristics in the organisation? These questions formed the essence of the study, using expectation, importance and experience as categories to distinguish the perceptions of respondents. The data was analysed using descriptive and inferential statistics. The results indicated that a gap does indeed exist between the espoused and actual EVP at SPAR EC. EVP attributes associated with people and their advancement, such as personal and career development opportunities, recognition provided to employees for exceptional performance, work-life balance and the level of involvement and empowerment of employees, were experienced to a lower extent in the organisation, when compared to the respondents’ level of expectation and how important they deem these attributes. It was therefore recommended that SPAR EC focus on these attributes, as employees determine for themselves the extent to which they experience “value” in organisations. Employees who view their organisations' EVP to be of less value are likely to withdraw, by either not contributing or by resigning from the organisation altogether (Heger, 2007).
