- Description: Activity-based costing is a cost allocation method which appears to have many benefits when compared to traditional costing systems. However, there is limited academic research demonstrating this superiority. There is thus a need to investigate and profile the characteristics of selected enterprises and their adopted cost allocation systems. The main objective of this study was to profile and compare the characteristics of companies in Nelson Mandela Bay that use the activity-based costing system, versus those using traditional costing methods. The research methodology used for this research study is descriptive and quantitative, using various techniques for data analysis. An electronic internet based questionnaire was distributed to companies and the response automatically recorded for analysis with the help of Nelson Mandela University statistics department. The findings of the empirical study revealed that most (38%) of the respondents use a combination of both activity-based costing and traditional costing methods, followed by traditional costing methods (35%), and purely activity-based costing (27%). Data analysis revealed that companies in construction and manufacturing seemed to prefer activity-based costing over traditional costing methods. The findings raise the question as to whether the preference in cost allocation methods is based solely on the benefits of cost allocation, lack of new knowledge, adaptability within companies, or cost of change versus the benefit.

- Description: The merger of institutions of higher learning in South Africa has demonstrated to the study an exploration of the role of strategic internal communication system – in the merging of the Walter Sisulu University. The purpose of the study is to determine to what extent employees of the Walter Sisulu University have perceived that the internal communication system of this university has contributed towards an effectively merged organisation. The study was conducted after three historically disadvantaged institutions of higher learning merged to form one comprehensive university. The three merged institutions are: the Border Technikon, the Eastern Cape Technikon and the University of Transkei. It was foreseeable during the process of the merger, that combining three institutions could possibly result in lower staff morale and uncertainty. The study has explored the theoretical framework for understanding the role of strategic internal communication systems in an organisation. The study was approached from a systems' perspective and that of a transformational model. A survey research design was utilised for the purpose of this study – in order to assess the validity and reliability of the data. A qualitative research design was used for the purpose of this study – in order to acquire the desired outcomes of the research. Questionnaires were used and the sample was drawn from a large population of the Walter Sisulu University – from, four campuses – with the aim of allowing one to make inferences about the population as a whole. The questionnaire was structured in four main sections namely: Biographical information, internal-communication systems, tools of internal communication, and line-management communication. The findings of the study aids the understanding behind the view of internal communication systems as having contributed – or not contributed – to a successfully merged university.

- Description: As the competition increase in the Higher Education industry, marketing departments of Higher Education Institutions view students as consumers and market their institutions. At the mean time, universities around the world encourage their international offices to increase the foreign student enrollments. This research investigates the factors influencing international students’ choice of enrolling at Higher Educational Institutions (HEI) via the internet: international students’ Internet use to facilitate information search and decision making. This survey of international students from Nelson Mandela Metropolitan University (NMMU) explored the Internet’s role in marketing international education. Based on this exploratory research, NMMU educational institutions gain insights of online customer service for successfully recruiting students. The results show that prospective overseas students do indeed use the internet. Overall evaluation of the factors influencing the use of the internet for enrolling at HEIs was determined by four factors: namely, perceived usefulness, consumer involvement, perceived ease of use and opinion leadership.

- Description: The giraffe at Nyaru were found to be browsers who made little use of graze during the study period. They utilized a diversity of 20 browse species. Two species, Acacia karroo and Acacia cyclops, formed the bulk of the giraffe diet throughout the year. A definite seasonal dietary shift was evident. A. karroo was favoured in summer and autumn and formed the main food species in spring, summer and autumn. A. cyclops was favoured throughout the study, but its contribution to the diet increased during winter when less A. karroo was consumed. This seasonal shift is related to the deciduous nature of Acacia karroo. Although a seasonal shift in species contribution to giraffe diet has been observed in many other giraffe feeding studies, no studies on giraffe feeding have been done in the Mosaic Thicket of the southern Cape. The ecological browsing capacity for giraffe in thicket was estimated to be between 0.020 BU/ha and 0.095 BU/ha. The browsing capacity for giraffe at Nyaru, based on the available phytomass 2–5 m above the ground, was estimated using those species that formed the bulk of the giraffe diet, and amounted to 0.063 BU/ha. A maximum of three giraffe could thus be stocked on the 157 ha of suitable giraffe habitat on Nyaru. This stocking rate recommendation lies within the range commonly recommended by local consultants for giraffe introductions into the southern Cape. Their recommendations are, however, not based on quantitative assessments such as performed in this study. The recommendation of this study should not be applied as a fixed ecological capacity for giraffe in thicket, but should be seen as a starting point in the adaptive management cycle. Ongoing monitoring of parameters, such as herbaceous composition and phytomass; as well as the condition of key browse species, is strongly advocated. A. karroo was browsed significantly more and carried significantly fewer pods per tree at a heavily used site compared to a lightly used site. Heavy browsing thus appears to affect the reproductive success of A. karroo significantly. Fewer pods are likely to lead to lower regeneration and thus reduced density of A. karroo. Whether A. karroo will maintain its dominance within the thicket vii community in the long run will be related to how individual plants survive and reproduce and if some can escape from herbivory. Fewer G. occidentalis were clumped with other species at the heavily used site compared to the lightly used site. This could possibly be attributed to the fact that intense browsing pressure at the heavily used site caused protective clumps to be eaten away, thus exposing G. occidentalis to higher ungulate browsing. Previous studies have found that nurse shrubs protect G. occidentalis against ungulate browsing. G. occidentalis was browsed significantly more at the heavily used site compared to the lightly used site. There was a general trend of fewer fruits at the heavily used site compared to the lightly used site, while fruits were absent on G. occidentalis growing alone at the heavily used site. This suggests a negative effect of heavy browsing on plant reproductive success and emphasizes the importance of nurse plants for the successful recruitment and hence long term prevalence of G. occidentalis in Mosaic Thicket.

- Description: The study investigated issues concerning procurement and administration in the Department of Health (DoH) in the Eastern Cape and has further investigated the role of the implementation of the Public Finance Management Act (PFMA), Act 1 of 1999 in the department. That included issues associated with the administration and procurement in relation to service providers from the private sector. The DoH in the Eastern Cape Province delivers:“ … a quality health service to the people of the Eastern Cape Province promoting a better life for all and ensures accessible, comprehensive, and integrated services in the province, emphasising the primary health care approach, as well as utilising and developing all resources to enable present and future generations to enjoy good health and quality of life” (Department of Health [DoH], Eastern Cape, Departmental Annual Performance Plan, 2013:3). Various researchers have investigated the implementation of the PFM Act 1 of 1999 and have identified gaps and made recommendations regarding the identified gaps. The study is based on the following reports from various authors: According to Pillay (2013), since 1994 every public sector department has lost approximately R385 billion to fraud, corruption and maladministration. Government employees have accepted kickbacks in exchange for rigging tenders, including focusing on high levels of corruption (Albert, 2011:1). The fraud and corruption in the Eastern Cape DoH, which involves nepotism, corruption and fraud amounting to a million rand in the audit report of 2013, have prompted calls by the opposition for interventions (PricewaterhouseCoopers [PWC], 2013:9). Departmental Annual Performance Plan for 2013/2014. Impact of accountability and ethics on public service delivery: a South African perspective which involves accountability stating that all government departments have to be efficient to ensure value for public funds including the qualitative and value-laden expectations of the society (Raga & Taylor, 2008:1). EC (2010:9), Audit Report: Health Department, Eastern Cape. King III Report (2009) – Corporate Governance. The study has built on previous research conducted by other researchers who have conducted research on the issue of the implementation of the Public Finance Management Act 1 (PFM Act 1) of 1999, and had identify further gaps not previously identified by other researchers or in the audits. In addition, this study aims to also identify shortcomings that have been described in the recent audits 2013/2014 of the DoH, Eastern Cape. Together with the new gaps identified in the PFM Act 1 of 1999, the researcher aims to make a number of recommendations to improve the effectiveness of the implementation of the PFM Act 1 of 1999. The PFM Act 1 of 1999 was promulgated by the South African government in 1999. The Act promotes the objective of good financial management in order to maximise service delivery through effective and efficient use of available limited resources as well as credible interaction with private sector service providers. A key objective of this Act is to put in place a more effective financial accountability system over public entities. The objectives of the Act are to: Modernise the system of financial management, Enable public sector managers to manage, while at the same time being accountable, Ensure timely provision of quality information, To eliminate waste and corruption in the use of public assets.

- Description: This research provides insight into the use of social networks and social media by students at the Nelson Mandela Metropolitan University. The primary purpose of this research is to investigate student social media practices at NMMU to establish the reasons for students engaging in social media. A growing number of educators acknowledge the potential of social networking to (re)engage learners with their studies, while others fear that such practices compromise and disrupt student engagement with traditional education provision (Selwyn, 2009). This study, therefore, aims to identify how and for what reasons students use social networks and social media. This study attempts to provide answers to the following research questions: For which social networking sites do students register and actively engage in? What is the most popular social networking site for students? How often do students engage in social media practices? What is the main purpose for students engaging in social media practices? How do students gain access to social media? For what educational purposes can social media be used? For which business purposes can social media be used? Do students use social media to collaborate with peers and lecturers? Do students use social media to make buying decisions? The literature overview was conducted on social media and social networks from journals and books published between the periods 2003 to 2011 as the popularity of social media came to the forefront during this period. Topics researched included social networks and libraries, educational and business uses of social networking and social media. A quantitative study was considered to be most appropriate to conduct the research for this study; and non-probability sampling was the most appropriate given the size of the population and the nature of this research. xiv Students were invited to participate in the research by completing and submitting a survey questionnaire at the conclusion of their lectures in the second semester during the month of September. The data collected was then analysed using descriptive and inferential statistics to provide insight into student use of social media. The results would determine if relationships exist between the independent variables from the questionnaire, namely, age, gender, campus and course enrolment and the dependent factors, namely, usage, information exchange and security. This relationship would be determined for both the perceptions of social networking in general and the perceptions of NMMU social networking. These results are then used to identify further areas of research in the future. The majority of the population sample was between the ages of 17 and 21 and primarily females. The sample typically became aware of social media by means of word-of-mouth and accesses their social networking site/s more than five times a day. The main reason for registering and joining social networking sites was for social purposes. Furthermore, the sample used social networking sites for entertainment, social involvement, meeting new friends and maintaining relationships. The sample agreed that social networking makes information searching easier. The majority of the sample indicated that they were not registered on any NMMU Social Networking sites of the university or any faculty, department or unit social networking sites at the NMMU. However, it was clear that the majority of students was registered on social networking sites of some sort and would continue to use social networking and social media. The results from the study indicated that the mean value for the perceptions of social media in general were greater than that of the perceptions of NMMU social media in terms of usage. Likewise, the mean value for the perceptions of social networking in general was also greater than that of the perceptions of NMMU Social Networking for information exchange but the difference were very small. However, the mean value for the perceptions of NMMU Social Networking showed a greater mean value than that of the perceptions of social networking in general in terms of security. This means that respondents used social networking in general more than NMMU Social Networking. xv However, the respondents perceived NMMU Social Networking sites to be more secure than social networking sites in general. The results of this study could provide Higher Education Institutions in South Africa with the impetus to use social networks and social media to enhance students‟ learning experiences.

- Description: The main purpose of this research project was to determine the fatigue-life behaviour of AISI 1008 sheet steel which has been mechanically formed to a radius of curvature of 120mm and then to correlate the fatigue-life behaviour to that of the parent or “as manufactured” material. During the forming process it was felt important to induce plastic strain through stretch-bending by clamping the sides of a plate sample’s (width) edges in the bending fixture before being bent by a single acting mechanical press. It was determined through actual testing that there was a decrease in fatigue-life when the mechanical formed data was compared to fatigue data of the parent material. Standard fatigue mathematical models were used to relate the actual fatigue data. Due to the material being cold formed to a radius of curvature of 120mm, residual stresses induced during the forming process played an essential role during the fatigue-life prediction calculations. The maximum relieved stress in the parent material was compressive in nature having a magnitude of 11percent of the “as manufactured” yield strength (265 MPa). For the mechanical formed material compressive residual stresses were measured on the outer surface while tensile stresses were measured on the inner surface. The difference between actual number of cycles to failure to that calculated using the standard mathematical models for the parent material, ranged between 48 percent and 18 percent and for the mechanical formed samples between 35 percent and 1percent, depending on the strain amplitude used. An important aspect of this study was to determine the criteria required for mathematical modelling of the parent material as testing occurred between the limit of proportionality and yield point. Although this aspect requires further investigation the mathematical results obtained during this study were considered to be acceptable.

- Description: With the world’s growing population and limited natural resources, there is a need to produce more food using less inputs. A major limiting factor to meeting the agricultural production needs of the growing population is fresh water. Water is a critical resource in agriculture and may be more of a limiting factor than other crop growth requirements in some areas. Furthermore, water availability is being impacted by climate change and competition from other industries. Methods of improving crop water use efficiency through conservation of water and the enhancement of crop growth need to be employed to meet the growing demand sustainably. The purpose of the research was to assess the differences in soil water status between organically farmed crops with a grass mulch and conventionally farmed crops without mulch, with a view to making more efficient use of the water resource. This research was conducted at the Mandela long term organic farming systems research trial site at Nelson Mandela University, George campus in the southern Cape, South Africa. It is part of a larger research project (the Mandela Trials) in which various researchers have been involved in different aspects of this trial including agronomy, microbiology and pest and disease control. This research took place over two seasons, namely, 2016-2017 season and 2017-2018 season. The soil water content (SWC) of organic and conventional plots were measured using fixed capacitance probes that recorded continuous data, every half hour, at depths of 10, 30 and 50 cm. A handheld theta probe was also used to measure the SWC in the top 6 cm of the soil at 7 to14 day intervals. The organic treatment had a significantly higher SWC than the conventional treatment over the two seasons in which this research was conducted. In addition, soil carbon was significantly higher in the organic treatment, than the conventional. Organic farming methods preserve and promote an increase in soil organic matter, thus improving the soil structure and increasing the soil’s water holding capacity. From this research, it is concluded that organic farming practices can be used to help conserve SWC, keeping it available to crops for longer and helping farmers make more efficient use of this scarce resource. This is especially relevant for low rainfall areas which are affected by water shortages. The improved SWC availability should be coupled with good agronomic practices to increase productive water losses and the conversion of water to yields, thus increasing water use efficiency. In addition, adding organic matter to the soil will improve resilience of the soil and help sequester carbon and thus help in mitigating climate change.

- Description: The creation and survival of SMEs largely continues to depend upon access to financing. When a financial crisis in the USA becomes a global economic crisis, SMEs and entrepreneurs all over the world suffer what can be called a double shock; a drop in demand for goods and services and a further tightening in credit terms. It becomes important therefore, to have a strategy on how to tackle the difficulties created by the crisis. Governments are trying to respond by helping to support sales and prevent bankruptcy of SMEs; by increasing access to liquidity, and by helping SMEs to maintain their investment level. Adequate responses of small businesses to the global financial crisis will determine how they will be impacted by the global financial crisis. Many research studies have shown how businesses behave in times of economic abundance. Although over ten economic recessions occurred during the past century, research on the response of businesses to financial challenges remains low. For this reason, the aim of this research was to demonstrate the response of small business owners and managers to the global financial crisis. To achieve this objective, the researcher used an integrated study method, as follows: A systematic literature review of the importance of small businesses in the economy and the implications of the global financial crises in the world and the South African economies. An empirical survey was conducted on small businesses in the Nelson Mandela Bay area in order to demonstrate their response to the global financial crisis. The results of the literature review and the empirical survey allowed the research to come to the conclusion that during times of financial challenges, small businesses decrease the number of people employed (only employ the people needed), increase efficiency through management, and reduce costs through efficient operations. This study contributes to the literature on small business responsive behaviour during times of economic crisis. As a result, this study presents recommendations and suggestions to assist owners and/or managers to respond appropriately to times of financial contraction.

- Description: White mold caused by Sclerotinia sclerotiorum attacks a wide host range of broad-leafed plants which includes potatoes. Current control is limited to the use of chemicals, but biological control has emerged as an eco-friendly alternative. For the study, 19 bacterial strains and 18 fungal strains obtained from soil samples taken from a potato field naturally infested with the pathogen S. sclerotiorum were tested for the effects on S. sclerotiorum mycelium growth and sclerotia viability in vitro. A total of eight bacterial strains and six fungal strains proved to be effective in the inhibition of S. sclerotiorum mycelium growth on PDA plate using a dual culture technique. These antagonistic microbes were six Bacillus subtilis, Bacillus pumilis, Bacillus marisflavi, Fusarium solani, Fusarium equiseti, Fusarium chlamydosporum, Aspergillus niger, Aspergillus insuetus and Penicillium citrinum. There was a significant difference (p<0.05) in the interaction between S. sclerotiorum mycelium growth and the time after inoculation with a S. sclerotiorum mycelium plug for both bacterial and fungal soil isolates. An additional sclerotia viability test was carried out using four of the eight antagonistic bacteria, and six of the antagonistic fungi. The results showed that two Bacillus species, namely B. pumilis and B. marisflavi can effectively reduce sclerotia viability. The other two bacteria (both B. subtilis), recorded low percentage reduction in sclerotia viability. As for the six antagonistic fungi, the viability test proved to be less effective in determining sclerotia viability. However, the result of this study supports the use of bio-control agents, not only because they are environmentally friendly, but because they are also an effective way of controlling the plant pathogen, S. sclerotiorum.

- Description: Horizontal axis wind turbines are by far the most common and well understood forms of wind turbine. Typically a large amount of research and development has been invested in the technology of large scale wind turbines. Unfortunately, development of small machines (rotor diameter smaller than 10 metres) has not been as forthcoming. The advantages of small turbines are that they are accessible to the individual consumer and they are a very attractive project for the home builder. The disadvantage of small turbines is that due to the negative influence of economies of scale, they tend to be costly in relation to their power output and suffer from a long-term return on investment. Furthermore, trends in the wind industry have shown that smaller machines tend to be relatively simple devices that have been developed with very little research and development. As a result, small turbines can be inefficient, unreliable and expensive to maintain. In many cases rotor design is less than optimal, with very little blade refinement. This is especially critical for small rotors due to low Reynolds Number operation. Further exacerbating the problem is that the rotors are typically not well matched to the generator. In many cases the machines are not suited to the wind speed range in which they are designed to operate, reducing the financial viability due to poor performance. It is envisaged that by applying optimising techniques and automating some of the design complexities into a software design tool, more cost-effective and viable machines can be developed that will deliver improved performance and therefore become more financially viable.

- Description: The human environment is under serious threat as natural resources such as air, water and forests are being overused. Worldwide, people have become more aware of the threatening situation and consequently many more individuals are showing concern for the environment. Often this concern is not displayed in consumers’ purchasing behaviour, as consumers who claim to be concerned about the environment are not necessarily consuming or showing a preference for environmentally–friendly products. This study examined two sets of variables, namely, person related and marketing related factors, and determined the extent to which these factors influence consumers’ behaviour when buying environmentallyfriendly products. The empirical data was collected by means of a survey, using self-administered questionnaires distributed to adult employed consumers residing in Port Elizabeth. Two hundred usable questionnaires were received. Three person related factors, namely, norms, environmental concern and environmental knowledge, and four marketing related factors, namely, price, product, place and promotion - were found to influence respondents’ behaviour when purchasing environmentally-friendly products. Environmental concern explained the largest portion of variation in purchase behaviour, while promotion explained the smallest portion of variation. Significant differences in the influence of age were found for norms, nvironmental concern, environmental knowledge and price. It is recommended that suppliers of environmentally-friendly products should ensure that these products are located at outlets which are convenient to consumers; more should be done by the relevant stakeholders to increase environmental knowledge and educate South Africans about the benefits of leading a more environmentally-friendly lifestyle; marketers find more innovative methods to convince consumers to act on their environmental concern; further attempts be made to minimise the price difference between environmentally-friendly products and traditional products; marketers should pay more attention to advertisements promoting environmentally-friendly products to ensure that these appeal to their target markets; and the performance of environmentally-friendly products should be on a par with the performance of traditional products.

- Description: The well-known concept of a Project Manager managing an I.T. project in relative isolation is no longer a viable option for organisations that are running numerous projects simultaneously. Due to the enormous costs and risks involved in many of these projects, there needs to be a means to ensure success. This has led to the establishment of the concept of a Project Management Office (PMO). An autonomous business unit that is responsible for managing all projects within an organisation. The need for a Project Management Office (PMO) to effectively manage multiple projects is becoming more and more accepted worldwide. The benefits of a PMO are well documented, but whether these benefits will apply to organisations within the NMM area needed to be investigated. A detailed analysis of the benefits of Project Management and in particular a PMO, have been investigated by means of a literature study. An investigation into the effectiveness of PMO’s in South Africa in general, was conducted by means of a survey targeted at a group of I.T. Project Managers located in all the major centres. A further survey was conducted among local I.T. managers to determine their current level of success and their expectations for the future. When reviewing the expectations of local I.T. management against the performance of Project Managers that are currently operating within PMOs, it is clear that organisations within the NMM area are in need of PMO’s and would certainly benefit from their establishment.

- Description: Customer relationship management (CRM) presents a new paradigm shift to the old traditional marketing strategies that are known and practiced by many organisations in South Africa and across the globe. Competition is not an excuse for failure anymore. Organisations that do not have any concrete strategies in dealing with the customer will not survive in the market. The ultimate goal of CRM is to enable organisations to forge closer ties with the customer so that a solid bond can be created to enhance loyalty and satisfaction. The goal for this research was to identify the CRM strategies used by a single organisation and thereafter suggest improvements to enhance customer loyalty. The results of the study could assist the management of the organisation to improve the CRM strategies which will hopefully enhance retention and prevent customer attrition. A literature review was conducted to unveil various elements of CRM, and strategies that can attract and retain customers. It helped in identifying themes for the empirical study. An in-depth interview was conducted with the general manager of the organisation to gauge his perception, and CRM practices in the organisation. An interview guide was used during the interview process. Four main topics namely: implementation of CRM, customer loyalty, customer complaints and conflict, and employees training and motivation were utilised for the interview guide and followed by further probing. Based on the responses obtained, analyses were made by comparing the responses to what literature revealed so that shortcomings could easily be identified.The study revealed that there were several inconsistencies with what was practised by the organisation and what the literature study revealed. Bearing in mind the shortcomings identified in the empirical study, the researcher made the following recommendations. The CRM implementation approach needs to be carefully planned with a clear defined vision and mission statement that focus on customer centredness. The organisation needs to invest in modern and innovative channels of communication and strategic partnership to reach the right customer. The organisation has to develop effective market segmentation and targeting to know the customer well. Consistent and highly relevant customer experiences should be drawn-on to fulfill the organisation’s promise of trust and reliability. The organisation should adopt competitive pricing strategy to limit customer sensitivity on price. The organisation should invest in employees’ development and welfare. Further research can be conducted to investigate the perception of other food retailers on the CRM strategies practiced. Further research can also be conducted in the organisation to investigate the perception of employees and customers on the CRM strategies practised.

- Description: ICT integration in secondary schools in Sub-Saharan Africa is still at an early stage and already faces several setbacks that may undermine the various initiatives undertaken by governments and the private sector to promote the use of computers in schools. Based on literature and other research, this may be attributed to the fact that no guidelines for proper ICT adoption in secondary schools exist; and furthermore, most integration cases were done haphazardly with no systematic approach based on the existing frameworks or tailored towards the real context in the schools concerned. The present study aimed to provide guidelines for the successful integration of ICT into schools in Cameroon. A review of some existing frameworks for ICT integrations in schools, as well as the innovative pathways that some developing countries have taken to ensure the successful integration of ICT into schools were explored through a literature review, revealing the trends and challenges of ICT integration in schools in Sub-Saharan Africa. The current status of ICT in schools in Cameroon being at an introductory stage was established from the available literature. This led to the use of a single case study from the Western Region of Cameroon, where four secondary schools were selected from the most advanced schools in terms of ICT integration. Participants consisting of principals, ICT co-ordinators, teachers, and students were interviewed, in order to establish the current status of ICT in each school, as well as those factors affecting or promoting the adoption of ICT. Teachers’ and students’ surveys, as well as existing documentation were used to triangulate the data gathered from interviews with school principals and ICT co-ordinators. Data were descriptively analysed – and the findings revealed that ICT is at the introductory stage of integration in the Fluck’s Model of ICT development in schools. At school level, the lack of infrastructure and an ICT adoption plan were found to be the key opposing factors to ICT integration, whereas several enablers were identified, such as the positive attitude of teachers towards ICT, the existence of a minimum recurring budget for ICT adoption through parents’ funding, as well as the continually decreasing cost of ICT infrastructure in the market. Based on the findings and experiences from successfully proven projects, a set of guidelines were derived for schools’ decision-makers. It is critical to put in place a well-structured policy for ICT in the school and to recognise all the ICT-related costs.

- Description: Malaria represents one of the oldest documented diseases among humans and even today organisms in the genus Plasmodium kill more people than any other infectious disease, especially in tropical and subtropical areas. The four most common species which infect humans are Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale and Plasmodium malaria. Of these four species, Plasmodium falciparum and Plasmodium vivax account for 95 percent of infections globally. Microscopy has been used since early days for the diagnosis of malaria because this method is simple, does not require highly equipped facilities, and in most cases enables differentiation among the species causing malaria in humans when performed by skilled microscopy readers. However, this method has been misleading in identifying parasite species, especially in the case of low level parasitemia, a mixed parasite infection, or modification by drug treatment as well as in placental malaria. Malaria rapid diagnostic tests (RDT) have played a major role in malaria management; particularly in providing blood based diagnosis in remote locations where microscopy based diagnosis is unavailable. These diagnostic tests are fast and easy to perform and do not require electricity or specific equipment. As part of strengthening malaria diagnostics in Malawi, the Ministry of Health and Population strongly recommends the use of malaria RDT’s at all levels of the health care delivery system. However, malaria microscopy remains a gold standard test for malaria. All patients (regardless of age) with suspected uncomplicated malaria should have a confirmed diagnosis with malaria RDT before anti-malaria treatment is administered. Based on field performance evaluations that assessed performance, quality control and production capacities of the manufacturing companies of malaria RDT’s, the Ministry of Health and Population recommended two brands of Histidine Rich Protein 2 (HRP-2), RDT’s for use in Malawi. These are SD Bioline malaria Ag Pf and the New Paracheck malaria Ag Pf. All these RDT’s are able to detect only P. falciparum. However, other species have been reported to exist in the country and there is a need to find proper RDT’s which will be able to detect all other species including P. falciparum. The main aim of this study was to evaluate Paramax-3 Pf/Pv/Pan RDT (Zephyr Biomedicals, India), if used in Malawi, could be able to detect and identify the different species of Plasmodium causing malaria in Malawi. The study recruited a total of 250 adult and infants at Bwaila Hospital in Lilongwe, Malawi. Study results showed that the overall sensitivity and specificity of the Paramax-3 RDT used in the study were 100 percent and 83 percent respectively. However, it was observed that the RDT test was not able to identify the P. ovale, and in some cases, the RDT test was positive for P. falciparum when the PCR identified the species as P. ovale. No P. vivax was detected both by RDT and PCR. This study was able to detect and identify the presence of P. malaria and P. ovale in Malawi apart from the P. falciparum. There were no significant differences between microscopy results compared to both the RDT and the PCR, with 94 percent and 98 percent sensitivities of R1 and R2 compared to RDT, as well as 94 percent and 96 percent sensitivities for R1 and R2 compared to PCR respectively. Both R1 and R2 had low specificities for example, R1 had 72 percent and R2 had 80 percent compared to RDT. Comparing R1 and R2 to PCR, the sensitivities were 64.9 percent and 67.2 percent respectively. However, the readers had difficulties differentiating the different species microscopically. The history of anti-malaria treatment had no significant effect on the outcome of the results in both the RDT and PCR.

- Description: The primary goal of the research is to investigate the extent of ICT adoption in secondary schools within the larger Port Elizabeth area. In order to demonstrate the current status, two geographical areas within that area namely privileged and less privileged areas will be selected and surveyed. The main objective of this research study is to survey the access to ICT services by learners and teachers living and working in less privileged communities compared with that of learners and teachers in the more privileged communities of Port Elizabeth. At present all the schools in these communities are funded by the same provincial government, but the extent of the digital divide is not known. This research will investigate the factors that lead to the inequalities in the access to ICT among secondary school learners and teachers. This research has the following sub goals and objectives: 1. To identify the factors that impact on the status of access to ICT services; 2. To determine which socio-economic factors contribute to the status of access to ICT services in the specific areas; 3. To determine the status of access to ICT services in specific communities within the larger Port Elizabeth area; 4. To determine whether the level of access differs between secondary schools and the homes of teachers and learners in the identified areas.
