  • Description: Due to innovation, Information Technology (IT) is changing all the time. One of the fast growing IT innovations is cloud computing. The phenomenon of cloud computing has changed the way that business consumes IT and in particular Enterprise Resource Planning (ERP) systems. This phenomenon has led to a need for research in the field of cloud ERP systems. A review of the literature revealed a gap in research related to cloud ERP systems and particularly to the adoption of these systems in South African companies. Only a few studies have been done regarding the adoption of cloud computing in South Africa, and the extent of adoption of cloud ERP systems in South Africa is not known. This study set out to answer the research question “What is the extent of understanding and adoption of ERP system in South African companies?” The study will be useful to the ERP industry in understanding the level of adoption of and perceptions about cloud ERP systems by South African companies. In order to answer the research question a survey research strategy was adopted and was of an exploratory nature. The sample was composed of IT professionals and line managers in South African companies. Questionnaires were sent via web link and 41 complete responses were obtained. The results showed that the respondents had a good understanding of the advantages/benefits of cloud ERP systems. However, a lack of clear understanding of the disadvantages/drawbacks of cloud ERP systems was evident in the research data which could lead to non-adoption of cloud ERP systems. Adoption of cloud ERP systems was highest in the engineering, manufacturing and IT sector. It was evident that IaaS and PaaS have not been adopted at all. The majority of the companies (60 percent) that had adopted cloud ERP systems were SMEs. This is in line with international studies that show that SMEs are driving the change in IT innovation such as cloud ERP systems.

  • Description: Great wealth of traditional knowledge about the use of plants had been transferred from generation to generations leading to the present day drug discovery and invention of new scientific methods of isolation, purification and identification. With the discovery of new diseases and drug-resistant organisms, there is no other source or deposit of lead compounds or drugs than the plant kingdom. As a result of this, about 25% of the current drug administered owe their origin to plant sources with the view to reduce the carcinogenic effect of synthetic drugs. Volatile terpenoids among other broad spectrum of natural product had been implicated to show high therapeutic properly. In the present study, selected locally-used medicinal plants were exploited for the presence of potent bioactive compounds and ability to form nanoparticles with distinctive property for use as chemoprotective agent against inflammation, tumors, cancer and other chronic diseases. Acacia mearnsii De Wild and Acacia karroo Hayne studied in this report are known to be invasive species with no proper regulation to conserve and preserve them. However, ethnopharmacology report of these plant species in the Southern Africa region reveals that they are good antiseptic, anti-diarrhea, anti-inflammation and a forage for livestock. These plants were subjected to volatile extraction protocol of some parts of the plants (stem and leaves) followed by examination of the anti-inflammation capacity of the extracts using an animal model. In addition, the bye-product (hydrosol) from the stem bark of each species possess a high reducing and stabilizing property leading to synthesis of silver nanoparticles, followed by investigation of the anti-inflammation potential of the synthesized silver nanoparticles using animal model. The volatile oils of the leaves and stem bark of Acacia mearnsii De Wild obtained by hydro-distillation were analyzed by Gas Chromatography-Mass Spectrometry (GC-MS). Twenty, Thirty-Eight, Twenty-nine and Thirty-Eight components accounting for 93.8%, 92.1%, 78.5% and 90.9% of the total oils of the fresh, dry leaves and fresh, dry stem bark respectively. The major components of the oil were octadecyl alcohol (25.5%) and phytol (10.5%); cis-verbenol (29.5%); phytol (10.1%) and phytol (23.4%) for the fresh leaves, dried leaves, and fresh stem, dry stem bark respectively. Oral administration of essential oils at the dose of 2% showed significant (p<0.05) anti-inflammatory properties in the albumin induced test model in rats. Oils from the fresh leaves and dry stems inhibited inflammation beyond 4 h post treatment. Furthermore, the chemical composition of the essential oils obtained by hydro-distillation from the leaves and stem bark (dry and fresh) of Acacia karroo Hayne, analysed by GC-MS, shows that hexanal (10.67%) and ß-ionone (9.74%) were dominant in the dried leaves, β-pinene (14.30%), and (Z)-2-Hexen-1-ol (10.21%) in the fresh leaves while Octacosane (10.59%) and phytol (23.38%) were dominant in the dry and fresh stem respectively. The anti-inflammation ability of these oils after an albumin-induced inflammation on wistar rats, shows a significant effect at the 1st h of treatment with a significance of P< 0.01 for all part plants, while the fresh leaves shows further inhibitory activities at the 2nd h of analysis. Silver nanoparticles (AgNPs) were successfully synthesized from AgNO3 through a green route using the aqueous extract (hydrosols) of Acacia mearnsii De Wild and Acacia karroo Hayne as reducing agent and as well as capping agent. The Acacia-mediated AgNPs were characterized with the use of UV-vis absorption spectroscopy, Fourier Transform Spectroscopy (FT-IR), Transmission electron microscope (TEM), Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDX), and X-ray Diffractometry (XRD). A spherical, 10-40 nm diameter silver nanoparticles were synthesized with very low level of stability for the AMDS and the AKDS-AgNPs. In addition, nociceptive activity with a mice rat reveals higher inhibition at the neurogenic phase for the AKDS-AgNPs, while AMDS-AgNPs exhibited a high inhibition at the inflammatory phase. The potent anti-inflammatory activity of essential oils of A. mearnsii De Wild and A. karroo Hayne hereby confirmed its traditional use in treating various inflammatory diseases, while the inflammatory studies on the synthesized AgNPs reveals a very active compound which can be used as a potent opioid or non-steroidal anti-inflammatory drug (NSAID).

  • Description: This paper examines the relationship between Israel's fortification of physical space and narratives of division in the Israeli occupied Palestinian West Bank Territory. I argue that the fortification and separation of physical space deepens segregation, and increases fear, hostility and disconnection between people living in this context. Furthermore, I suggest that this relationship between narratives of division and insecurity and structural mechanisms of control within the West Bank influences and impacts on individuals such that personal perspectives become guarded and defensive. The mediation of subjects through a defensive lens can prevent individuals from forming connections that acknowledge the permeability of seemingly impenetrable distinctions between inside and outside, or self and an-other. The looking, recording and representation of people in a place that is guarded and framed from a position of insecurity reduces the capacity of individuals to locate openings that traverse restrictive boundaries. In order to contextualise my discussion, I have included personal documentation of defensive structures photographed in the West Bank between 2013 and 2014. I position my observations and analyses in relation to discussions about the Oush Grab Military Base presented by the Decolonizing Architecture Art Residency (DAAR) in their recent publication Architecture after revolution (2013).

  • Description: This study seeks to investigate the underlying ideologies and practices behind the perception that women who are in command positions are unable to command and control, especially those who are in the operational environment. The study was executed in the Eastern Cape Province (Eastern Cape), in Buffalo City Metropolitan Municipality (BCM). The research participants (respondents) were constituted by 33 police officers from diverse police stations within the BCM. The participants were divided according to gender, i.e. 24 females and 9 males. With regards to objectives of the study, the aim was to investigate the following issues: i) to understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinateslcolleagues and community members. ii) To understand factors that make women not to be accepted in their positions as SAPS' operational commanders, by their male subordinates/colleagues and community members, and iii) to explore strategies to utilize in making SAPS' women operational commanders, survive while managing their day-te-day respective units/components effectively and efficiently. Regarding research design, this study mainly used a qualitative research method combined with a bit of a quantitative approach. And then the data collection method involved making use of semi structured interviews to all the respondents. The results of this study show that there is still a huge difference in the number of women who are commanders compared to their male counterparts, especially in those environments that were previously regarded as male dominated. Further, despite the necessary training being provided by the SAPS to women officers, the necessary support in particular from management is still a challenge. Lastly, the argument of this study is that there is still not a fair representation of women in command positions within the SAPS, especially, in the previously male dominated environments.

  • Description: Gold exploration in the laterite terrains of the Siguiri basin (Guinea-West Africa) is discussed in this thesis. It seeks to propose and develop effective and reliable geochemical exploration techniques applied in such laterite terrains. The study is also intended to investigate and provide some geological clues as to why, in some target areas, the reconnaissance test drilling across the geochemical anomalies couldn’t intersect economic gold mineralisation. Targets were generated based on soil geochemical results, some of which were drilled without delivering economic discoveries even on areas with strong and consistent geochemical signatures. To find the failure and define the appropriate methods to be used is the core of the thesis. More importantly, the geological observation is aimed at sourcing and establishing the nature and validity of geochemical anomalies within the license area and their relationship with the underlying lithologies and structural networks. The geological field work conducted during this study is mostly based on regolith and surface geological mapping. The thick laterite cover, deep weathering, bedrock geology, gold geochemistry (the gold geochemical anomalous results are defined according to historical data before 2007), soil formations and variations in climate conditions are emphasized to illustrate the importance of mineral element mobility and dispersion in the weathering profiles. The knowledge and experience in regolith geochemistry and regolith mapping provide the advantage to exploration geologists. The depletion of ore resources and reserves in Siguiri and the continuous decline of the gold price in comparison to the complexity of exploring for gold are demanding more scientific-related thoughts and techniques to be integrated in the available geological, geochemical and geophysical information so as to reduce costs. The integration of good exploration strategy and technique may result in the possibility of making viable discoveries in this highly competitive geological environment where the mineral resources become depleted every day.

  • Description: The Hsp70/Hsp90 organising protein (Hop), also known as stress-inducible protein 1 (STI1), has received considerable attention for diverse cellular functions in both healthy and diseased states. There is extensive evidence that intracellular Hop is a co-chaperone of the major chaperones Hsp70 and Hsp90, playing an important role in the productive folding of Hsp90 client proteins. Consequently, Hop is implicated in a number of key signalling pathways, including aberrant pathways leading to cancer. However, Hop is also secreted and it is now well established that Hop also serves as a receptor for the prion protein, PrPC.

  • Description: Geological and geophysical methods were used to investigate the southeastern Karoo Basin of South Africa in an area extending from longitudes 24 o E to 29o E and latitudes 32o S to 35o S. This was undertaken in order to reveal geologic structures, isochore thicknesses of the geologic sequence and their variations across the study area, proffer the possible provenance of the sediments and assess the potential of oil and gas accumulation. The methodology used includes field investigation, rock sampling, preparation of thin sections, petrographic studies, X-ray diffraction analysis, density measurements, porosity calculations, extraction of elevation data from Google Earth, 2½ D gravity profile modelling, generating of isochore (true vertical) thicknesses and depositional surfaces maps from the models, PetroMod 1D modelling and qualitative interpretation of magnetic, gravity and radiometric maps.Petrographic study was carried out on twenty six thin sections of rocks from the eleven geologic formations that cover the study area. Petrographic studies on the diamictite of the Dwyka Group shows abundance of monocrystalline quartz, granite and quartzite components in the breccias which possibly indicate the existence of granitic and metamorphic rocks in the source areas. The sandstones of the Ecca and Beaufort Groups are immature, greywacke and the heavy mineral assemblages signify that the minerals are of granitic, volcanic and metamorphic origin. The magnetic maps show two main magnetic anomalies, a major one trending in a northeast to southwest direction which is part of the Beattie magnetic anomaly and another that is a “bean-shaped” anomaly. The radially averaged power spectrum shows two depths to magnetic sources. The first depth is about 0.6 km which is the average depth to the top of the shallow sources, while the average depth to the top of the deep sources is about 15 km. The shallow sources are connected to magnetic minerals within the Beaufort Group while deep magnetic sources were inferred to be in the basement. The gamma ray spectrometric map shows areas with relatively high gamma radiation count. The high radiation count is possibly due to the uranium and thorium in the detrital materials, as well as the enrichment of radioelements in the feldspars (k-feldspar), calcite, quartz, zircon and clay minerals in the fluvial channel sandstones of the Beaufort Group. A total of two hundred and fifty-eight (258) rock samples were collected in the field and densities (dry, wet and grain densities) and porosities were determined in the laboratory. The Karoo Supergroup density values range from 2.526 – 2.828 g/cm3. The average porosities range from 0. 49 – 3.31 %. The dry densities and porosities of all the formations are inversely correlated with correlation coefficient values (R) that range from 0.9491 - 0.9982. The density of the dolerite intrusions (mostly sill) ranges from 2.700 – 2.837 g/cm3 whilst the porosity range from 0.1118 – 0.3868 %. The Bouguer anomaly map shows an increase in gravity values from -140.7 mGal in inland to about 60.1 mGal in coastal areas. This dominant gravity variation is inferred to be due to a deeper basement and/or Moho that get shallower from inland towards the coast. The Moho is at about 45 km depth inland and shallows to about 42 km at the coast. The 2½ D gravity modelling was done for fourteen (14) profiles with each profile having three (3) models corresponding to minimum, average and maximum densities to obtain the thicknesses of the geologic sequence. The current isochore thicknesses extracted from the gravity models show that the Beaufort Group is the thickest of all the groups that make up the Karoo Supergroup with maximum vertical thickness of up to 634 m, followed by the Ecca and Dwyka Groups with maximum vertical thicknesses of about 3207 m and 727 m, respectively. The maximum elevation for the Dwyka, Ecca and Beaufort sediments are about 500 m, 400 m and 285 m, respectively, whilst the maximum depth below sea level are around 8500 m, 7000 m and 5500 m, respectively. The PetroMod1D model result yield average vitrinite reflectance and temperature values of about 6 % and 500 ℃ respectively for the lower Ecca Group which belong to the dry gas window based on classification by several authors. Thus the rocks of the lower Ecca Group are thermally matured for hydrocarbon (shale gas) generation that can merit gas exploration in the Karoo Basin.

  • Description: Igshaan Adams is a young artist from Cape Town, working in multimedia and performance. In his practice, Adams brings ways of seeing and also ways of being into consideration through meditations on objects, dreams, Sufism, family relationships and the changeability of self-hood through perception of these phenomena. This paper engages with Adams' affinity with objects, their agency and biography,and considers how his sensitive interventions alter their materiality, shifting the ways in which they can be seen. The ways in which Adams' family relationships play out in the processes of making his sculptural works, and also in his performances, are then elucidated and related to his ongoing processes of self-enquiry. Furthermore, I consider Adams' latest body of work, a critical enquiry into the variable meanings of Rorschach inkblots. Adams reflects on the grounds for inkblot testing and, in so doing, tests and measures the nature of looking, perceiving and projecting.

  • Description: The aim of this study was to investigate the socio-economic perceptions of the beneficiaries of the low income housing scheme in Unit P, of Mdantsane Township, under Buffalo City Metropolitan Municipality. Both quantitative and qualitative approaches were utilised in this study. For instance, questionnaires on the perceptions were administered amongst twenty (20) beneficiaries of this low housing scheme. Semi structured interviews were conducted amongst five (5) respondents who participated in the survey design. The study found that the intervention of providing poor people with houses was not appropriately done as these houses are too small and therefore fail to consider the families of the beneficiaries although the South African government seems to have succeeded to some extent in providing low income housing for the unemployed and those that belong to the low income category. The study also found that the location of Unit P poses a threat because it is located away from all the amenities compelling the beneficiaries to travel more than 5km to the amenities and essential services. The study therefore recommends that the government employs competent contractors that would do a proper job. State officials, tasked with overseeing the various state funded housing projects, have to ascertain the success of these projects by making sure that the contractors do not lack skills such as the ability to facilitate projects of a high magnitude as that could lead to flawed projects. They should be constantly monitored and post evaluated. This will help to minimize the wasting of state resources.

  • Description: We report here for the first time on the photophysical and nonlinear optical behavior of tetra-substituted alkynyl zinc phthalocyanine and its “clicked” analogue (4 and 5). The compounds exhibited high triplet quantum yields in dimethylsulphoxide (DMSO). Nonlinear optical (NLO) properties were also evaluated for the two compounds at 532 nm and 10 ns in DMSO. We observed two-photon absorption (2PA) and strong reverse saturable absorption (RSA) as the dominant mechanisms at nanosecond laser excitation. The presence of electron acceptor groups fused with triazole linkers in the peripheral positions of 4 provide excellent coexistent features, such as enhanced triplet quantum yields and lifetimes compared to 5. Large third-order susceptibility (2.09 × 10−11 and 3.53 × 10−9 esu) and hyperpolarizability (1.09 × 10−30 and 9.13 × 10−29 esu) were estimated for complexs 4 and 5, respectively.

  • Description: In this article, the nonlinear optical characterizations and optical limiting properties of metal-free (2), zinc (3), and indium (4) tetra 4-(2-mercaptopyridine) phthalocyanines are discussed. Nonlinear optical properties of the samples were evaluated using Z-scan at 532 nm and 10 ns pulse in CHCl3, and doped on poly(bisphenol A carbonate) (PBC) thin films. Thin films for 2, 3, and 4 are represented as 2-PBC, 3-PBC, and 4-PBC, respectively. We observed two-photon absorption (2PA) and strong reverse saturable absorption as the dominant mechanisms at nanosecond laser excitation in solution and thin films. By virtue of the magnitude of absorption coefficients and other nonlinear optical parameters estimated in this work, sample 4 was found to exhibit strongest nonlinear optical properties followed by 3, while 2 is the weakest nonlinear absorber of the studied samples. Large third-order susceptibility (1.46 × 10−9 esu and 7.74 × 10−10 esu) and hyperpolarizability (2.13 × 10−28 and 8.37 × 10−29 esu) were estimated for 4-PBC and 3-PBC, respectively. Our studies show that these molecules are suitable candidates for practical passive optical limiters. , Original publication is available at http://dx.doi.org/10.1080/00958972.2015.1077237

  • Description: Initially in feminist circles, and subsequently in more common usage, the term ‘survivor’ came to signify those who have been (sexually) violated and live on, and even thrive. The passivity implied by the term ‘victim’ therefore gave way to the more agentic connotations of ‘survivor’. However, neither term adequately captures the complexity and fluidity of subject positions taken up by and ascribed to women who have been subjected to sexual violence. The selection of an inadequate word is not neutral: each identifier calls forth particular identity constructions which have real effects. Reducing women’s experiences to one pole of this simple binary can diminish and totalise those experiences. In this paper we re-consider the use of these terms with reference to research conducted with protestors participating in an annual anti-rape protest held at Rhodes University, Grahamstown, South Africa. We focus on the perspectives of women who are ‘survivors’ of sexual violence.

  • Description: Research with persons who have experienced trauma requires careful consideration. In preparing the ethics protocol for an ethnographic study of an anti-rape protest, we thought carefully about how the first author would manage ethical decisions in accordance with the University ethics code. However, this process did not prepare us for the dynamic and reciprocal positioning the first author encountered in the field. Nor was she prepared for her sense of the ethical duty of response when entrusted with the narratives of women who had suffered ‘irredeemable harm’. Drawing on the philosophy of Emmanuel Levinas, and examples from the research, we show how ethical decision-making in ethnographic research is always relational and dialogical; extending beyond our direct interactions with participants to the ways in which we approach our ‘data’. We argue that ethics cannot be reduced to a cognitive-rational process and propose ways to acknowledge and draw on the ‘affective’ and ‘transcendent’ in our ethical decision-making.

  • Description: This study explored and described the perception of clinical psychologists regarding thebarriers to the provision of psychological services in urban public health settings for people with first-episode schizophrenia. The qualitative research study utilised an explorative, descriptive interpretive research design. Purposive sampling was utilised to gain access to clinical psychologists, who had at least two years of public health experience working with people recently diagnosed with schizophrenia. Data was gathered from 11 participants from the Nelson Mandela Bay Health District of the Eastern Cape by means of in-depth interviews that were conducted in English by the researcher until data saturation had occurred. A computer-assisted qualitative thematic analysis of the collected data was conducted using NVIVO software. The findings have been categorised according to three broad domains: 1)contextual barriers 2)health care system-related barriers and 3)first-episode schizophrenia syndrome-related barriers. Several specific sub-themes were identified for each of these main domains allowing for recommendations and suggestions to be provided for attending to and overcoming these perceived barriers.

  • Description: Growth in information and communication technology (ICT) is drastically changing the way businesses, especially in the service industries, are conducted. The financial services industry and banking in particular, is not excluded from this technology explosion. Internet banking, even though not new in advanced countries, is a new transaction channel being used by banks in some parts of Africa, especially Ghana, to offer various products and services to their customers. However, this medium has not been fully exploited by these banks as there are many hurdles the banks must triumph over. In deploying this technology and these systems, there are several factors which banks must take into consideration before fully deploying such a system to their customers, hence the motivation for this study. The absence of suitable and sufficient knowledge on this topic also exposes a “rhetoric versus reality” argument of whether the intention to adopt Internet banking is critical to the strategies and ultimate success of banks in Ghana. For banks to stay ahead of competition as well as to attract and maintain their clientele, it is of paramount importance to gather and link the perspectives of both clients and bank managers in order for banks to ensure that they perform according to the needs and expectations of their clients. In order to achieve the intended results, an empirical study was conducted by taking into consideration the viewpoints of both bank clients and bank managers in determining the factors that customers take into consideration before adopting the Internet banking medium. The primary aim of this study was to quantify significant relationships between the selected variables. Therefore the positivism research paradigm was used, while the phenomenological paradigm was employed for the measuring instruments. Because multiple sources of data were used, from the perspectives of banking clients and managers in Ghana, methodological triangulation was adopted for this study. The results of the empirical investigation showed that both groups (clients and managers) considered the variables of market share, technology acceptance, diffusion of innovation, organisational variables, organisational efficiency, and business strategy to have direct influence on the adoption of Internet banking. However, they differed in opinion concerning the degree of influence of these variables. The bank managers’ responses leaned more towards strong agreement with the importance of these variables than did those of the bank clients. Thus, for bank clients to readily adopt the Internet banking medium for their banking transactions, bank managers must take a closer look at these determinant factors described in the study. The study showed that the population group, educational and income levels exerted an influence on the perceptions clients have regarding Internet banking adoption factors. It was found that the higher the education and income levels of the clients, the easier it was for them to adopt Internet banking. Also, the male group dominated the use of the Internet banking. This is supported by the fact that there is a growing middle class in Ghana that falls within this category of banking clients.

  • Description: South Africa has emerged as one of the most important renewable energy markets as reflected by the USD 5.5 billion invested in South Africa in 2014 (Merger’s Alliance, 2015). As the opportunity exists for South Africa to take advantage of its above average natural wind resources, the main purpose of the case study research effort was therefore to develop a theoretical sustainable training framework in support of the rapidly growing wind power industry in South Africa. The proposed location for a sustainable training support framework is at the NMMU Business School and Leadership Academy, strategically located in the Eastern Cape. In addition, the NMMU Business School and Leadership Academy has satellite offices all around South Africa, thus creating accessible training and education solutions to most parts of the country. The case study research approach was qualitative in nature, thus providing valuable insight into the case study phenomenon. The researcher focused on a single context, namely the wind power industry in South Africa, and within a single case of the establishment of a sustainable training support framework at the NMMU Business School and Leadership Academy. The embedded, multiple units of analysis comprised of a purposive sample of strategic individuals operating within the South African wind power sector, socio-economic development, education and training industries. In staying within the research design, the case study made use of an in-depth interview process in order to address the research propositions of the case study. The investigative interview questions were fully supported by secondary sources of information. The case study provided valuable insight into the unique South African wind power industry setting, with a focus on education and training in line with the REIPPPP minimum threshold and targets for socio-economic development and job creation. The researcher experienced a lack of responses from industry experts who were contacted for interviews. This lack of response could be considered as a limitation in validating the outcome of the study. The South African wind power industry is one of the most thriving markets in the world (Merger’s Alliance, 2015) and due to its fledging nature; research on the topic under discussion is not readily available. Thus, the research effort provided relevant information regarding the unique setting of the South African wind power industry and added value through the proposition of a sustainable training support framework strategically located at the NMMU Business School.

  • Description: Background: Agriculture plays a vital role in the economy of any industrially developing country, including South Africa. In the Eastern Cape of South Africa citrus farming is a significant contributor to the local economy (Johnson et al., 2005). The harvesting phase of citrus farming is performed manually and exposes workers to physical risks, which can lead to the development of musculoskeletal disorders. In particular, the standard harvesting bag comprises of a single shoulder strap and promotes asymmetrical load carriage which results in shoulder and lower back pain complaints. The current study compared the physiological (EMG), perceptual (RPE), usability (PUEU) and productivity effects of two new harvesting bag designs (a hip belt and a backpack bag design) to the standard harvesting bag design. This was performed in a laboratory as well as a field setting. Methods (Laboratory phase): 36 participants (12 males and 24 females) were assigned to one worker group. The “tall ladder worker” group was comprised of only males and the “step ladder worker” and “ground worker” group of females. Each participant was required to simulate a citrus harvesting task while utilizing each of the bag designs on different days. On each day/test session, participants performed three harvesting cycles. Muscle activity was measured throughout the entire testing session and RPE were recorded at the end of each cycle. Results (Laboratory phase): The EMG and RPE results indicate that the backpack design was the most ideal design to reduce asymmetry, while the standard harvesting bag design was the worst. Although not significant, there was greater muscle asymmetry (p=0.109) and a significantly higher perceived exertion when using the standard bag (p=0.0004), in comparison to using the backpack. Methods (Field phase): 17 Xhosa-speaking citrus harvesters (6 females and 11 males) participated in this study. Each harvester worked with one of the three bag designs on a different day. Productivity of each worker was assessed every hour by recording the number of bags filled with fruit and at the end of the shift. A Perceived Usefulness & Ease of Use questionnaire was presented to each participant to obtain feedback on worker acceptance to the new bag designs. Results (Field phase): A general trend in support of the hip belt bag design over the other two bag designs were found, even within the different worker demographic groups (age, sex and worker experience). The workers perceived less exertion (7.98 ± 1.86) and were more productive (9.90 ± 2.11 bags/hour) when using the hip belt design; they also found this bag the most useful (1.02 ± 0.09) and easy to use (1.07 ± 0.25). In contrast, the backpack bag design had significantly poorer responses when compared to the other two bag designs and this was evident in all the dependent variables assessed (RPE, productivity and PUEU). Conclusion: The results from the laboratory phase supported the expectation that the backpack bag design reduces asymmetry and hence, is more suitable than the standard harvesting bag. However, results from the field show that the hip belt bag design was the most preferred and the backpack was the least preferred. Bao & Shahnavaz (1989) highlight the need for ergonomics researcher to convey laboratory findings into the field context. However, as shown by the current study, there are numerous challenges associated with field work, making it difficult for laboratory findings to be successfully conveyed to the field. Limitations and Recommendations: For the laboratory phase of the project, no biomechanical and cardiovascular responses were assessed. However, for a holistic approach, these variables should be considered in future studies. Due to high variability from one harvesting cycle to another, more than three harvesting cycles should also be performed to accurately replicate the harvesting process as done in the field over extended durations of time. For the field phase, data should be collected from more than one citrus farm and thus a larger sample size could be obtained. This would improve the validity of the study. In addition to this, data should be collected for a full working day, especially if environmental conditions are not a hindrance, as well as for a whole season, since workloads vary, depending on the time of the harvesting season. , Name on Graduation Programme: Bassey-Duke, Elizabeth Missan

  • Description: Pharmacological interventions to treat Human Immunodeficiency Virus (HIV) with antiretrovirals (ARVs), have dramatically improved the survival rates of HIV positive children maturing into adulthood. However, HIV-associated neurocognitive decline still persists in the era of ARVs. Within the framework of brain plasticity, a number of researchers have begun to assess the feasibility of cognitive rehabilitation therapy as a complement to ARVs to reverse neurocognitive decline as a result of HIV (e.g., Becker et al., 2012). Only one study has been conducted in South Africa, by Zondo & Mulder (2014), assessing the efficacy of cognitive rehabilitation in a paediatric sample. The current research builds on the above mentioned study by implementing an experimental approach to examine the effect of cognitive rehabilitation in a sample of both HIV positive and HIV negative children. Five HIV positive and six HIV negative children were assigned to either an experimental or control group. The experimental group underwent two months of cognitive rehabilitation therapy remediating sustained attention, whereas the control group took part in placebo activities. Sustained attention measures were taken before and after the intervention training sessions, using a sustained attention subtest from the Test of Everyday Attention for Children (TEA-CH). A Mann Whitney U Test revealed that the experimental group (Mdn=38.50) did not differ significantly from the control group (Mdn = 37.00) after the cognitive rehabilitation intervention, U=12.00, z= -.55, p= .66, r= -.17. But a Wilcoxon Signed Rank Test found that there was a significant improvement from pretest scores (Mdn=31.00) to posttest scores (Mdn=38.00) following the rehabilitation for HIV positive participants in the sample, T=15.00, z = -2.02, p= .04, r= -.90. This raises the possibility that cognitive rehabilitation could be used as a low cost intervention in underdeveloped contexts
