- Description: HIV/AIDS is undoubtedly the single most important and daunting health problem facing Africa. Globally too, this is one of the most serious health, medical and social preoccupations of our time (Chinery-Hesse, 2000: 1). The aim of this research study is to evaluate the strategic impact of HIV/AIDS on first level component suppliers to the motor industry located in the Nelson Mandela Metropole. To achieve this aim a literature study was undertaken to determine the patterns of development, the infection statistics and to explore strategic options and actions for dealing with the effects of the disease. An empirical study has been conducted to assess the opinions of senior management within first level component suppliers. The results from the study indicate that most companies in the selected group believe that HIV/AIDS will have a serious impact on their organisations. In conclusion, various recommendations have been made with regards to the findings ascertained in the literature review and empirical study.

- Description: Education is commonly seen as an escape from poverty and a critical path to securing a better standard of living. This is especially relevant in the South African context, where the need is so great that in one instance people were trampled to death at the gates of a higher educational institution, whilst attempting to register for this opportunity. The root cause of this great need is a limited capacity and a demand, which outstrips the supply. This is not a problem specific to South Africa. It is however exaggerated in the South African context due to the country's lack of infrastructure and the opening of facilities to all people. Tertiary educational institutions are faced with ever-increasing applications for a limited number of available positions. This study focuses on a dataset from the Nelson Mandela Metropolitan University's Faculty of Engineering, the Built Environment and Information Technology - with the aim of establishing guidelines for the use of data modelling techniques to improve student admissions criteria. The importance of data preprocessing was highlighted and generalized linear regression, decision trees and neural networks were proposed and motivated for modelling. Experimentation was carried out, resulting in a number of recommended guidelines focusing on the tremendous value of feature engineering coupled with the use of generalized linear regression as a base line. Adding multiple models was highly recommended; since it allows for greater opportunities for added insight.

- Description: The research problem addressed in this study was to determine what makes a work team successful. To achieve this objective a theoretical model of factors promoting team effectiveness was developed, using relevant literature in which models for team effectiveness are described. The theoretical model consisted of the following factors: Individual background factors; Facilitation; Team Factors; Synergy; Team effectiveness; Organisational factors. Each factor of the model was broken down into dimensions that were then analysed using literature identified during the literature study. The theoretical model was then used to develop a questionnaire to test the degree to which managers working for automotive component manufacturers in the Port Elizabeth /Uitenhage magisterial district and falling under Chapter III of the Bargaining Council for the Motor Industry concur. The empirical results obtained indicate a strong concurrence with the theoretical model of factors promoting team effectiveness that was developed in the study. This resulted in the theoretical model being confirmed and being accepted as a model of factors promoting team effectiveness.

- Description: Surface temperature measurement is applicable to a vast number of fields including manufacturing, processing, agricultural, medical and pharmaceutical fields just to name a few. Two methods for obtaining surface temperature measurements exist; ‘surface contact measurement’ in which the measuring device makes physical contact with the surface in question or alternatively, ‘non-contact surface measurement’ where there is no contact at all. Both of these methods have got advantages, as well as disadvantages. However, in recent times, non-contact methods have been preferred since they are non-intrusive and allow for remote measurements to be made. In this research, a non-contact mobile temperature measurement system is developed. The system is microcontroller-based and uses infrared sensors to acquire temperature measurements. The infrared sensors are mounted on a three-axes, x-y-z coordinate system which allows a thermal profile of a particular surface to be generated and displayed on a Graphical User Interface (GUI) in real-time. Various tests were carried out to compare contact and non-contact measurement methods; to determine the most suitable operating height for accurate non-contact measurement given a specific surface and to investigate the benefit of single and/ or multiple sensor arrangements. The research showed that a non-contact thermal scanning system could be used to obtain detailed yet accurate surface temperature measurements following an initial sensor calibration phase to determine the most favourable scanning parameters for a particular surface. The measurements taken could then be used to generate a thermal map of a surface with a significant improvement in resolution as compared with measurements taken using contact devices. The research further showed that a multiple sensor arrangement significantly reduced the time taken to generate the thermal profiles without undermining accuracy.

- Description: Globally agricultural rangelands have been subjected to degradation through over-utilization. The loss of productivity of agricultural rangelands around the world has led to the development of methods to restore the productivity of these areas. In South Africa, extensive areas of the Nama-Karoo have been degraded or transformed due in part to unsustainable agricultural activities. The development of restoration methods which are easily implementable and financially viable could increase the probability of stakeholders implementing restoration activities on privately owned land. The removal of the degrading factor is not sufficient to reverse the degradative trend in dryland environments. Active measures must be implemented to arrest the degradation cascade. The climatic conditions of the rangelands of South Africa are limiting to plant performance and the favourable conditions are sporadic. The translocation of plants should be combined with the amelioration of the local conditions. This study tested the restoration technique of microcatchments in association with plant translocation. The effects of microcatchments and planting combinations which were best suited to the survival and performance of the transplants were determined through a field trail. The results showed that microcatchments created microsites which were conducive to transplant survival and growth, including nutrient accumulation and increased soil moisture. The success of the method was dependent on the planting combination used. Plants which are adapted to inundation and the saline conditions of the site performed better. Plants which were older at the time of translocation had higher survival rates than younger transplants. In the conditions of this site, planting adjacent to the microcatchments was necessary to avoid inundation induced mortalities. The environmental conditions of the Nama-Karoo necessitate the coordination of restoration activities with the predicted favourable conditions in order to improve the success of restoration activities.

- Description: Motor impaired people are faced with many challenges, one being the of lack integration into certain spheres of society. Access to information is seen as a major issue for the motor impaired since most forms of interaction or interactive devices are not suited to the needs of motor impaired people. People with motor impairments, like the rest of the population, are increasingly using mobile phones. As a result of the current devices and methods used for interaction with content on mobile phones, various factors prohibit a pleasant experience for users with motor impairments. To counter these factors, this study recognizes the need to implement better suited methods of interaction and navigation to improve accessibility, usability and user experience for motor impaired users. The objective of the study was to gain an understanding of the nature of motor impairments and the challenges that this group of people face when using mobile phones. Once this was determined, a solution to address this problem was found in the form of natural user interfaces. In order to gain a better understanding of this technology, various forms of NUIs and the benefits thereof were studied by the researcher in order to determine how this technology can be implemented to meet the needs of motor impaired people. To test theory, the Samsung Galaxy s5 was selected as the NUI device for the study. It must be noted that this study started in the year 2013 and the Galaxy S5 was the latest device claiming to improve interaction for disabled people at the time. This device was used in a case study that made use of various data collection methods, including participant interviews. Various motor impaired participants were requested to perform predefined tasks on the device, along with the completion of a set of user experience questionnaires. Based on the results of the study, it was found that interaction with mobile phones is an issue for people with motor impairments and that alternative methods of interaction need to be implemented. These results contributed to the final output of this study, namely a set of user experience guidelines for the design of mobile human computer interaction for motor impaired users.

- Description: Organisations of the future have to focus strongly on sustainability to meet the needs of and ensure the survival of future generations. Many organisations either ignore environmental issues or address these issues superficially. To become a green organisation, requires a change in attitude, knowledge and behaviour and therefore a change in organisational culture. The purpose of this study was to explore Human Resources strategies for developing and implementing a green organisational culture in organisations. To address the main problem and the identified sub-problems, a literature study was undertaken. The concept of sustainability was explored, the rationale for going green and major stakeholders in creating a green organisational culture were identified. The literature study provided a synopsis of previous research on HR strategies for managing a culture change and more specifically, for creating and implementing a green culture in organisations. The research revealed that leadership, communication, recruitment, orientation, training, performance management, reward and recognition initiatives, as well as discipline, could be used to develop green values, attitudes and behaviours among organisational members. A web-based survey with a questionnaire as data collecting instrument was conducted among public and private organisations in the Nelson Mandela Bay Metropolitan area to determine the extent to which these organisations used the identified HR strategies to create a green organisational culture. A snowball sample technique was used. The main factors surveyed, included leadership, green technologies, green communication, HR strategies and procedures, brand communication and brand image. The results confirmed that executives or senior management were the main drivers to create a green culture; however, even though these leaders were considered passionate about the environment, they did not optimise the vision values and strategy to build a green organisational culture. The study also confirmed that although these organisations used green technologies to reduce waste, they did not encourage or reward employees for their contributions to green initiatives and did not adequately use communication in this respect. The results revealed that of the factors surveyed, leadership and HR strategies or procedures contributed the most to organisations developing a green organisational brand or image. The study confirmed the importance of using an integrated approach to develop a green organisation. Such an approach is initiated by senior management, through the formulation of a green vision, green values and a green strategy, and is supported by both technological resources and employee contributions. In addition, HR strategies should be aligned vertically and horizontally to develop an appropriate green mind-set and behaviour among all organisational members. In this respect, the HR department should also model appropriate green behaviours.

- Description: Over the last several years studies have shown that the quality of indoor air may be worse than outdoor air. People spend as much as 90% of their time indoors, therefor, the associated health risk due to indoor air pollution may be greater than the risk due to outdoor air pollution. Building designs have altered dramatically over the last two decades resulted in "tighter" buildings that rely on sophisticated mechanical systems to provide for the quantity of air required throughout the building. These changes over the years could result in an increased number of complaints received regarding Sick Building Syndrome symptoms. The World Health Organization (WHO) estimates that up to 30% of office buildings world-wide may have significant problems regarding poor indoor air quality (IAQ). This study involves a literature study of the major indoor air pollutants regarding the source of the pollutant, the associated health effects, the measuring techniques available and the results of previous studies conducted on the specific pollutant. Measurements will be taken in two sealed buildings, one an old and the other a new building to identify the major pollutants. A questionnaire was compiled specifically for building occupants and completed by the occupants of both buildings. From the results obtained a step-by-step method for solving indoor air quality (IAQ) problems was proposed. The method was applied and evaluated in a case study of a problem building where indoor air quality related problems were experienced. The results of the study revealed that the major indoor air pollutants are present in old as well as new buildings. The study also revealed that some office workers might be more susceptible than others to the medical reactions cause to human beings by these pollutants. Some concentrations are higher in new buildings than in old buildings. The responses from the questionnaire was evaluated against the results obtained from the measurement study. The step-by-step method in the case study provided a more systematic approach at solving IAQ problems at buildings. Solving indoor air quality problems is a very practical issue and does not necessarily require an investment of expensive high technology equipment, but might merely require a practical approach. Environmental Health Officers can play a major role in providing expert advice when scrutinizing building plans. Environmental Health Officers should empower themselves with the knowledge to do inspections or investigations in office buildings by using the step-by-step method for investigating indoor air quality problems. By addressing indoor air quality problems in buildings, the workers in healthy buildings can increase their productivity with lasting effects on a company’s bottom line.

- Description: Over the last several years studies have shown that the quality of indoor air may be worse than outdoor air. People spend as much as 90% of their time indoors, therefor, the associated health risk due to indoor air pollution may be greater than the risk due to outdoor air pollution. Building designs have altered dramatically over the last two decades resulted in "tighter" buildings that rely on sophisticated mechanical systems to provide for the quantity of air required throughout the building. These changes over the years could result in an increased number of complaints received regarding Sick Building Syndrome symptoms. The World Health Organization (WHO) estimates that up to 30% of office buildings world-wide may have significant problems regarding poor indoor air quality (IAQ). This study involves a literature study of the major indoor air pollutants regarding the source of the pollutant, the associated health effects, the measuring techniques available and the results of previous studies conducted on the specific pollutant. Measurements will be taken in two sealed buildings, one an old and the other a new building to identify the major pollutants. A questionnaire was compiled specifically for building occupants and completed by the occupants of both buildings. From the results obtained a step-by-step method for solving indoor air quality (IAQ) problems was proposed. The method was applied and evaluated in a case study of a problem building where indoor air quality related problems were experienced. The results of the study revealed that the major indoor air pollutants are present in old as well as new buildings. The study also revealed that some office workers might be more susceptible than others to the medical reactions cause to human beings by these pollutants. Some concentrations are higher in new buildings than in old buildings. The responses from the questionnaire was evaluated against the results obtained from the measurement study. The step-by-step method in the case study provided a more systematic approach at solving IAQ problems at buildings. Solving indoor air quality problems is a very practical issue and does not necessarily require an investment of expensive high technology equipment, but might merely require a practical approach. Environmental Health Officers can play a major role in providing expert advice when scrutinizing building plans. Environmental Health Officers should empower themselves with the knowledge to do inspections or investigations in office buildings by using the step-by-step method for investigating indoor air quality problems. By addressing indoor air quality problems in buildings, the workers in healthy buildings can increase their productivity with lasting effects on a company’s bottom line.

Hoofstuk 1 is ‘n literatuurstudie bestaande uit ‘n algemene inleiding wat agtergrond oor die studie verskaf en sluit die probleemstelling in, naamlik die swak oorlewing van volstruiskuikens wat onder kunsmatige toestande grootgemaak word. Hoofstukke 2, 3, 4 en 5 bestaan uit die eerste vier studies, waartydens sekere bestuurs-aspekte, wat moontlik oorlewing van volstruiskuikens kan verbeter (nl: populasiedigtheid, tipe vloer-oppervlak, die aanwending van broeipare en die aanwending van peetouers), ondersoek is. Hoofstukke 6, 7, 8 & 9 handel oor studies wat gerig is om voeding meer aanloklik te maak vir volstruiskuikens teneinde voedselinname te stimuleer en sodoende produksie en oorlewing te verbeter (nl: verskaffing van groenvoer, geur van voer, kleur van voer en beligting van voer). Die laaste hoofstuk bestaan uit ‘n algemene gevolgtrekking en aanbevelings.

- Description: In view of the factors influencing and the steps in the design of a Website, building a successful Website will vary from business to business. This study investigates what is required from a small commercial and industrial property and services business to take their business online and create an effective Website. The environment of the property market reflected the role that government plays in the property industry and also the role of the private sector. Marketing in the real estate context indicated that if real estate agents have access to the right type of information, not only can they add value to their own organizations, but they can also capitalize on the same information to create added value for their clients. The elements of the marketing management process include four steps, namely to gather information, to set marketing goals and plan strategy, to organize and implement marketing strategy and to control the marketing activities. Marketing in the online environment showed that the Marketing Mix includes personalisation, privacy, customer services, community, site, security and sales promotion. The principles of online marketing revealed the important role of the customer and customer relationships. An investigation into the difference between e-commerce and online marketing made it clear that online marketing is one component of e-commerce. This study critically analysed the available literature in order to suggest a proposed framework of what should be included in the Website of a small commercial and industrial property and services business. In order to successfully research online marketing of commercial and industrial properties and services in a small business, a basic but thorough understanding of online marketing principles and Website content are important. In this study a qualitative research approach was followed where secondary sources were critically evaluated to design the required framework. Thereafter three Websites of marketing of commercial and industrial properties and services were content analysed to see whether anything else should be added to the framework. This would assist in taking a small business in commercial and industrial properties and services online. The framework suggests that the Website homepage content should include: Business overview/information Products/services What’s new Search Employment opportunities Interactive feedback Customer service/ assistance Index/directory Financial facts Links to other sites Online business services/utilities Guest book Frequently Asked Questions Messages from CEO A purposeful sample of three Websites was then content analysed so as to provide the information necessary to reach the objectives of the study. The following Websites were included in the content analysis: Broll, which operates as a national agency with international associations. The firm renders services (Estate Agency) and does not own property. Bruce McWilliams Industries Pty Ltd is operative in Port Elizabeth, Uitenhage and surrounds. It is a family business that owns property, which it develops and markets itself. Seeff is a national agency. It renders services (estate agency) and does not own property. Lastly, a narrative of a small commercial and industrial property and services business was created by means of document analysis of a specific business. The researcher was allowed to study the documents and diaries of the business in order to provide a narrative for this business. This narrative can be used as part of the envisaged Website for the business.

- Description: The human being is commonly considered as being the weakest link in information security. Subsequently, as information is one of the most critical assets in an organization today, it is essential that the human element is considered in deployments of information security countermeasures. However, the human element is often neglected in this regard. Consequently, many criminals are now targeting the user directly to obtain sensitive information instead of spending days or even months trying to hack through systems. Some criminals are targeting users by utilizing various social engineering techniques to deceive the user into disclosing information. For this reason, the users of the Internet and ICT-related technologies are nowadays very vulnerable to various social engineering attacks. As a contribution to increase users’ social engineering awareness, a model – called SERUM – was devised. SERUM aims to cultivate social engineering resistance within a community through exposing the users of the community to ‘fake’ social engineering attacks. The users that react incorrectly to these attacks are instantly notified and requested to participate in an online social engineering awareness program. Thus, users are educated on-demand. The model was implemented as a software system and was utilized to conduct a phishing exercise on all the students of the Nelson Mandela Metropolitan University. The aim of the phishing exercise was to determine whether SERUM is effective in cultivating social engineering resistant behaviour within a community. This phishing exercise proved to be successful and positive results emanated. This indicated that a model like SERUM can indeed be used to educate users regarding phishing attacks.

- Description: There are thousands of different wine brands available and wineries have to build a relationship with their customers, a relationship that will create a long-lasting experience. The relationship starts with the first interaction they have with the winery (Alonso et al 2008:978). Visitors to the tasting room create the opportunity to build long-term relationships (O’Neill & Charters 2000:113; Nowak & Newton 2006:157), build and develop brand loyalty (Dodd & Gustafson 1997:43), increase wine sales (Gilinsky et al 2003:18), and improve cash flow (Jago & Issaverdis 2001:18). The subject of repurchasing intentions in the wine industry has attracted the attention of numerous researchers; in particular, the connection between winery visits, brand loyalty and post-visit consumer behaviour (Nella & Christou 2010:2). Nederburg is one of the most prestigious South African wine estates, with a deep-rooted history in South Africa as one of the biggest wine brands. It is 100% owned by wine and spirits giant Distell and presents an ideal case for investigating the influence of the relationship between quality, customer satisfaction and price on repurchasing intentions in the South African wine industry. The purpose of this research was to determine whether the tasting room experience, in combination with a quality product, good pricing and customer-focused operations, leads to higher customer satisfaction and repurchase intentions. The present study indicates that the South African wine industry faces many challenges but it also highlights the various opportunities there are for wine estates to not only increase their sales but also to build long-lasting relationships with consumers. The study concludes with recommendations to the South African wine industry on how to improve their tasting room environment so that they can benefit from the relationship between wine quality, wine price, customer satisfaction and repurchasing intentions.

- Description: The issue of construction workers’ motivation has become a subject of debate among construction project management professionals. Construction workers mostly work long hours in relatively disagreeable environments and, far from their families. Most of the activities are done under difficult conditions including harsh weather conditions, however, employees are required to be motivated towards ensuring the attractiveness of the industry to them. Moreover, there are diverse perceptions that the motivation of construction workers positively impacts construction workers performance or rather adversely affects the general performance of construction workers. Although, workers motivation has been proven to improve construction productivity globally, motivation of construction workers seems not to be effectively implemented in South African Construction Industry. As a result, it is difficult for management to identify motivational factors that affect workers productivity in a work environment. A quantitative research approach was employed to analyse the result obtained from a structured questionnaire survey. The research respondents included: bricklayers, plumbers, concrete workers, electricians, carpenters, and professionals. This study used data from primary source which focus on tradesman, labourer and professional context. A survey was conducted with tradesmen, labourers and professionals regarding motivation on construction workers which was conducted in the Nelson Mandela Bay Metropole, Eastern Cape. It was found that motivation is important to construction workers’ performance. Awarding bonuses to workers is important to improving workers’ efficiency and there is a need for construction workers recognition by management. Construction industry stakeholder should shift their attention and prioritise the motivation of its workers since the industry has a way of cubing poverty and uplifting the county’s economy. The findings revealed that motivational communication, rather than functional communication, would enhance worker productivity. It was found that both intrinsic and extrinsic rewards are needed to improve worker productivity. It was also found that positive reinforcement techniques, should be used to enhance worker productivity. The findings from this research study revealed that the motivational theories apply to construction workers, and management needs to apply these theories wisely to achieve improved productivity. The study therefore concludes that motivational techniques are necessary to improve construction workers productivity on a vii construction site. It is recommended that supervisors use motivational communication, extrinsic rewards, intrinsic rewards and positive reinforcement to motivate their workers to achieve higher levels of productivity.

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 purpose of this study is to investigate specific contributing factors affecting quality assurance in the diagnosis of conventional cervical smears. More than half of South- African women fail to have one cervical smear in their lifetime and +/- 50 percent of those who do have cervical smears taken, are lost to follow-up. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen all women in South Africa, due to far-off rural areas, shortage of medical professionals and the lack of knowledge of some women of the necessity of cervical smears. Many newly qualified South-African doctors leave the country to go and work elsewhere. South Africa then in turn has to recruit doctors from other countries to staff the State hospitals and clinics. Some areas have one doctor to thousands of patients, insufficient nursing personnel and inadequate equipment. Doctors in some areas cannot cope with the volume of work and the long hours. One has to accept that the quality of the management of some patients is affected negatively. There are a number of medico-legal issues (world wide) in relation to aspects of cervical cancer prevention practices which are controversial and are of particular concern to all of those involved in cervical cancer prevention. Various countries have therefore formed different national organizations to address the medico-legal issues in screening for the prevention of cancer. These organizations monitors procedures, internal quality control as well as external quality control. In South Africa, medico-legal cases are not so prevalent, but may become so shortly. The South-African medical professionals therefore have to ensure that their quality of work conforms to accepted good practice in all circumstances. State hospitals serve thousands of patients per month and it is an every day occurrence to see long queues of patients sitting waiting for doctors and who often have to come back the following day. The situation appears to be much improved in private practice and since patients have medical cover and accessible medical facilities. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen 100 percent of women in South Africa, due to far-off rural areas, the shortage of medical professionals and ignorance of patients. Quality assurance is therefore of paramount importance to every medical professional for every patient treated. Laboratories all worldwide have been, or are in the process of being accredited by their specific accreditation authorities. The main reason for this is improvement of quality control and therefore quality assurance. The South African National Accreditation Society (SANAS) now accredits various laboratories in South Africa with the view of accreditting all laboratories within a certain time limit. The Ampath laboratory Port Elizabeth was successfully accredited during 2001. Accredited laboratories have to uphold a very high degree of quality to remain accredited. A team of professionals inspects the laboratory every 2 years and other quality assurance staff inspects the laboratories every few months. All aspects of the laboratory are checked, e.g. the qualification of staff, their registration with the Health Professions Council of South Africa (HPCSA), their curriculum vitaes, equipment, safety of the laboratory etc. Since the laboratory chosen for this study, is accredited, the author evaluated every cervical smear that was received in the laboratory since the year 2000, with the following objectives in mind: · Whether the presence or absence of an endocervical component has an effect on the adequacy of cervical smears · To determine the effect of using smaller coverslips on quality assurance in the cytology laboratory · Evaluate the effect that manual re-screening of smears has on quality assurance in the cytology laboratory. As there is a shortage of cytotechnologists and pathologists worldwide, several countries make use of automated screening devices as primary screening or secondary screening for quality assurance. These devices were tested in some laboratories in South Africa but were found to be very expensive and sensitivity and specificity were not up to standard. Sensitivity is a measure of the ability of a test to detect the abnormal - Sensitivity is the ratio of true positives to true positives + false negatives. Specificity is a measure of the ability of a test to correctly identify the negative - Specificity is the ratio of true negative to true negatives + false positives. The automated screening machines failed to identify abnormal cells amongst inflammatory cells, as well as in very blood stained smears. Several other problems also occurred and an increasing number of smears had to be manually rescreened, thus making this exercise costly and not helpful as a quality assurance instrument. The slides used for this thesis, have been retrieved from the archives of the Ampath laboratory in Port Elizabeth. Fourteen specific contributing factors affecting quality assurance in the diagnosis of cervical smears are also discussed and conclusions and recommendations given.
