- Description: A doctoral study was embarked upon with the intentions of addressing cost management problems encountered on Infrastructure Delivery Projects in South Africa. Given that poor cost performance constitute hindrance to the realization of project goals, it is imperative to eliminate it from project delivery. The prevalence of cost overrun in public sector projects is a call to all stakeholders to address cost management issues in the construction industry. The predominance of cost overruns in public sector construction projects in South Africa has been observed. With the decline of the current economic conditions in South Africa, project performance is a great concern that needs attention. In addition, ineffective initiatives to curb the abuse of the procurement processes are directly affecting the outcomes of construction projects, and if these status quo remains, the sector will continue to have a bad image and continued waste of taxpayers’ money will not cease until the public sector remove non-value adding activities in their operations. Study adopted a mixed methods designed that collected both textual and statistical data. Semistructured interviews were undertaken to determine the outcomes of current project management practices in South Africa. In terms of performance of projects, the status quo paints a disconsolate picture. Findings reveal protracted processes, and the use of unqualified and inexperienced contribute to poor performance of public sector projects. Poor performance continues to dominate the construction sector, especially in the public sector. Interviews data were contrasted with evidence from project-related documents. Based on the data, the study produces a vignette of existing cost management frameworks applied to such projects. Encompassing various stages of the project delivery lifecycle, this vignette will enable an identification of the challenges afflicting cost management on projects. Accordingly, this study identified Lean opportunities from existing cost management practices. Such opportunities will enable identification of effective cost management during project delivery. There appears a need for collaborative cost management practices. Lean tools mentioned for improvement include the 5Whys, the big room, target value design, and the integration of design and construction. A collaborative cost management framework was developed through relevant theories to improve the cost management process of public sector projects.

- Description: Governments, internationally and nationally, are becoming aware of the importance of healthy work environments within their health departments, environments that are caring and supportive to health professionals. This awareness is brought about by the mounting evidence that healthy work environments are critical to recruiting and retaining health professionals. On the other hand, unhealthy work environments can contribute to medical errors, ineffective delivery of care, and conflict and stress among health professionals in the clinical setting and faculty shortage that can compromise academic excellence in the academic setting. The professional nurses working in the South African Military Health Service (SAMHS), a branch of the South African National Defence Force (SANDF) could experience the military environment as unhealthy because it is rigid and controlled. The hierarchical rank structure could deprive them of their autonomy as the decision-making powers are directly proportional to the rank. Stressful conditions could be experienced when these professional nurses are taken away from the well equipped hospital environment to the deployment areas away from home. There was, however, no evidence found on the work environment of professional nurses in the SAMHS during literature review. The aim of the study is therefore to explore and describe the experiences of professional nurses working in the SAMHS and their understanding of a healthy work environment and the scope and nature of a best practice guideline, then to integrate the evidence generated to the evidence emanating from the critical appraisal of the existing best practice guidelines from other health settings in order to develop a best practice guideline for a healthy work environment for nurses in the SAMHS. The study adopted a qualitative, exploratory, descriptive and contextual research design. The research study was made up of three phases. In Phase 1, semi-structured interviews were conducted with professional nurses to collect information on their experiences of working in the SAMHS and their understanding of evidence-based best practice guidelines. The interviews were transcribed by an independent transcriptionist and data analyzed using the eight steps of data analysis as suggested by Tesch. Themes were identified and grouped together to form new categories. The process of coding was supported by an independent coder. Lincoln and Guba’s model of Page | vii trustworthiness consisting of credibility, transferability, dependability and confirmability was used to ensure the validity of the study. An integrative literature review was conducted where the existing evidence-based best practice guidelines for healthy work environment for nurses were searched for, appraised, had data extracted and were synthesized in Phase 2. In Phase 3, evidence generated in Phase 1 and Phase 2 was triangulated, forming recommendations that were utilized to develop a best practice draft guideline for a healthy work environment for professional nurses working in the SAMHS. The draft guideline was sent to five expert reviewers for their comments and recommendations. These were considered in the development of the final guideline. The final guideline consists of several recommendations in four themes: the need for effective leadership to create an empowering environment; effective communication amongst members of the health team; a culture that supports team work, and; the need for an environment that promotes professional autonomy. Further recommendations were made to address factors that impact negatively on enhancement of a healthy work environment. The guideline is intended for use by SAMHS’ leadership, at Levels 2, the strategic level, Level 3, the formation level and Level 4, the unit level (hospitals, sickbays and clinics and nursing college) and all professional nurses working in all the military health institutions of the SAMHS, including the military clinics, sickbays and hospitals irrespective of positions. However, the guideline may also be adapted by nursing institutions outside the military such as public and private hospitals and clinics where they find it applicable. Results

- Description: Clinical teaching is a critical component of the education and training of undergraduate nursing students. It determines the level of clinical competence that nursing students achieve during their studies. It should be informed by current best practice evidence available in the nursing care literature (Emanuel, Day, Diegnan & Prys-Muller, 2011:21-22). Clinical teaching is centred around provision of patient care in clinical practice. It takes place through an interaction between the nurse educator and the nursing students. During this process nursing students are moulded so they can demonstrate minimum competency in order to be registered by the regulatory body. Nursing students learn to become competent nurses in the clinical learning environment (Baxter 2006; Nash, 2007 in Franklin, 2013:35). In South Africa nurse educators are required to be fully responsible for clinical teaching through the use of appropriate teaching approaches and learning facilitation techniques (RSA DoH, 2013:91). The overall purpose of the current research study was to explore and describe the current clinical teaching practices of nurse educators; to search, appraise, extract and synthesise literature related to clinical teaching in nursing; and to develop A Best Practice Guideline for Clinical Teaching at a Public College of Nursing in the Eastern Cape Province. This had to be realized in three phases. In Phase One a quantitative, exploratory, descriptive and contextual study was conducted. A structured questionnaire was used to collect data from the nurse educators involved in clinical teaching within the Diploma in Nursing (General, Community, Psychiatric) and Midwifery programme. The data analysed was used as the basis of Phase Two—namely, an integrative literature review of evidence pertaining to the clinical teaching practices of nurse educators doing clinical teaching within the undergraduate programmes. The evidence from Phases One and Two was used to develop a draft Best Practice Guideline. The draft guideline was reviewed by a group of expert reviewers and their suggestions were incorporated in the final guideline. Ethical considerations were maintained throughout the research study. The rigour of the research process was ensured by cognitive testing of the questionnaire, and by critical appraisal of the literature accessed from an integrative literature review. The v authenticity of critical appraisal was ensured by having the critical appraisal done by the researcher and an independent reviewer.

- Description: Due to the complex nature of chorioamnionitis, women are often misdiagnosed, undiagnosed or only diagnosed after birth when it is too late to prevent maternal and neonatal complications. A lack of a comprehensive best practice guidelinefor screening and managing women withchorioamnionitis resultsin delayed treatment and management that could minimise maternal and neonatal complications. Saving Babiesreported that unexplained intra-uterine deathsremained the main primary (obstetric) cause of death for babies with a weight above 1000g (24.4%of all deaths). Of these unexplained uterine deaths, 33% are of normal birth weight (>2500g), and,therefore,most likely term gestation. Saving Babies further reported that 22.9% of all live births in South Africa was premature and 22.8% of birthswere unexplained intra-uterine deaths. Prematurity is one major complication of chorioamnionitis. When susceptibility for chorioamnionitis is considered during early pregnancy, it is possible to intervene and prevent or even reduce the incidences and complications of chorioamnionitis.A qualitative research study was conducted in three phases. In Phase One(Part One), a theoretically constructed patient scenario of chorioamnionitis was presented to ten midwives,and semi-structured individual interviews were done to elicit information regarding how they screen for and manage chorioamnionitis. In Phase One(Part Two), experienced medical practitioners in the field of obstetrics and gynaecology were individually interviewed, also using semi-structured individual interviewsto gain their views regarding chorioamnionitis as a contributing factor to maternal morbidity and mortality. Qualitative findings in Phase Oneindicated that there is a general lack of knowledge regarding chorioamnionitis among midwives, resulting ininadequate screening, misdiagnosis and mismanagement of the condition. Experienced medical practitioners confirmed that chorioamnionitis is underdiagnosed, misdiagnosed or undiagnosed and underreported,and they hold views that it is difficult to treat and control pregnancy-related infections according to current practice.An integrative literature review was conductedin Phase Twoand literature regarding diagnostic biomarkers, screening options to diagnose chorioamnionitis and management of chorioamnionitis were extracted. After evidence synthesisofPhase Oneand Phase Twodata, a best practice guidelinefor screening and managing viiwomen withchorioamnionitiswas developed usingthe National Institute for Health and Clinical Excellence guideline development approach in Phase Three. The purpose of the best practice guideline for screening and managing women with chorioamnionitis was to provide a guideline onhow to manage women who are at risk and those who present with signs and symptoms of chorioamnionitis at any stage during their pregnancy. Five recommendations were made that involve screening for chorioamnionitisand causative factors, biomarkers to diagnose chorioamnionitis, management of chorioamnionitis that includes pharmacological and non-pharmacological management, and health education to women.Ethics for this research study were guided by the ethical principles and guidelines of the Belmont Report. The trustworthiness of this research study was adopted from Ravitch and Carl,and was based on criticality, reflexivity, collaboration, and rigour. An independent coder and reviewer wereto verify the data that were included in the best practice guideline.

- Description: The retention of persons on an HIV programme has been a global challenge. The success of any strategy to optimize adherence to anti-retroviral therapy (ART) depends on the intensive and effective adherence counselling and strategies. It is important to research whether persons receiving anti-retroviral therapy in public hospitals in Ghana are receiving the needed service that would optimize their adherence to the anti-retroviral therapy. Therefore, this study explored and described the experiences of healthcare professionals providing care, support and guidance to persons on ART at public hospitals in Ghana, as well as the best-practice guideline that could contribute to facilitating the ART adherence of patients. This study also explored and described the experiences of persons living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) on ART, regarding their adherence to the therapy. The study was organized into three phases. In Phase One: a qualitative, exploratory, descriptive and contextual design was employed. The research population included healthcare professionals, providing services at the HIV clinic at the public hospitals in Ghana, namely the Korle-Bu Teaching Hospital; the 37 Military Hospital and the Ridge Hospital. The healthcare professionals comprised of doctors, nurses, pharmacists and trained counsellors employed in any of the three public hospitals. Persons receiving ART at any of the three public hospitals were also part of the research population. Semi-structured interviews were conducted with healthcare professionals and persons receiving ART. Data were collected from healthcare professionals in relation to their experiences regarding the provision of ART services, their understanding of evidence-based practice and best-practice guidelines, as well as data on the experiences of persons receiving ART in relation to their adherence to the therapy. The data were analysed using Creswell’s six steps of data analysis; and the coding of the data was done according to Tesch’s eight steps of coding. Trustworthiness was ensured by using Lincoln and Guba’s framework which comprised credibility, transferability, dependability, confirmability and authenticity. Ethical principles such as beneficence and non-maleficence, respect for human dignity, justice, veracity, privacy and confidentiality were considered in the study. In phase two, the literature was searched by using an integrative literature review approach and critically appraising the methodological quality of the guidelines in order to identify the best available evidence related to adherence to ART. In Phase Three, a best-practice guideline for facilitating adherence to ART was developed for public hospitals in Ghana based on the findings of the empirical research of Phase One and the integrative literature review in Phase Two. The guideline was submitted to an expert panel for review; and it was modified, according to the recommendations of the panel.

- Description: The South African Higher Education Act 101 of 1997 provides a legal framework for the management of higher education institutions based on quality assurance and accountability. As such, the Act mandates the introduction of performance management. Performance management is one of the most challenging areas of responsibility in the field of human resources management. The literature, as discussed in this study, reveals that performance management is a complex phenomenon and that the implementation of a performance management system is, for a variety of reasons, not always successful. Failure is mostly attributed to not taking a planned, scientific and collaborative approach to implementation, resulting to lack of buy-in from significant stakeholders. Specifically, the introduction of performance management in the higher education sector presents a unique challenge, as the process requires that stakeholders and especially academics, to shift from a traditional culture of collegiality to one in which accountability is measured by formal criteria. While existing literature does address the management of change in organisations, there is a paucity of literature on managing change with regards to performance management and specifically in the context of higher education. The purpose of this study was to develop and present a comprehensive change framework for introducing performance management in higher education. In order to provide a theoretical basis for the research, existing literature on performance management, change management as well as the higher education context was reviewed, to identify potential barriers to the implementation of performance management. A case study analysis was conducted on the implementation of performance management at a comprehensive university, which included presenting a historical timeline of implementation based on documented evidence, and reporting on open-ended interviews and focus groups conducted with significant stakeholders. The stakeholders included management, Human Resources (HR), academic staff, administrative and support staff, as well as trade union representatives. Key lessons were drawn and fused to develop a change framework for the introduction of performance management in higher education. The framework encapsulates key themes extracted from the literature and empirical study, with regard to readiness for change, planning, implementing and sustaining change, with cognisance of the unique context. The research revealed critical aspects for the successful implementation of performance management communication with and the involvement of stakeholders, the commitment of senior management, training, embedding the change in the organisational culture, and constantly evaluating the progress as a feedback loop for making improvements. The study demonstrates that planning the change process helps to improve the effectiveness of implementing performance management. A process framework for developing and introducing performance management in the context of higher education is created with a focus on how to create ownership through communication and involvement. The proposed framework serves as a valuable resource for researchers and practitioners, especially those involved in higher education.

- Description: The frequency and magnitude of landslide occurrence in the Kigezi highlands of South Western Uganda has increased, but the key underpinnings of the occurrences are yet to be understood. The overall aim of this study was to characterize the parameters underpinning landslide occurrence in the Kigezi highlands. This information is important for predicting or identifying actual and potential landslide sites. This should inform policy, particularly in terms of developing early warning systems to landslide hazards in these highlands. The present study analysed the area’s topography, soil properties as well as land use and cover changes underpinning the spatialtemporal distribution of landslide occurrence in the region. The present study focussed on selected topographic parameters including slope gradient, profile curvature, Topographic Wetness Index (TWI), Stream Power Index (SPI), and Topographic Position Index (TPI). These factors were parameterized in the field and GIS environment using a 10 m Digital Elevation Model. Sixty five landslide features were surveyed and mapped. Soil properties were characterised in relation to slope position. Onsite soil property analysis was conducted within the landslide scars, auger holes and full profile representative sites. Furthermore, soil infiltration and strength tests, as well as clay mineralogy analyses were also conducted. An analysis of the spatial-temporal land use and cover changes was undertaken using satellite imagery spanning the period between 1985 and 2015. Landslides were noted to concentrate along topographic hollows in the landscape. The occurrence is dominant where slope gradient is between 25˚ and 35˚, profile curvature between 0.1 and 5, TWI between 8 and 18, SPI >10 and TPI between -1 and 1. Landslides are less pronounced on slope zones where slope gradient is <15˚ and >45˚, profile curvature <0, TWI <8 and >18, SPI <10 and TPI >1. Deep soil profiles ranging between 2.5 and 7 meters are a major characteristic of the study area. Soils are characterized by clay pans at a depth ranging between 0.75 and 3 meters within the profiles. The study area is dominated by clay texture, except for the uppermost surface horizons, which are loamy sand. All surface horizons analysed had the percentage of sand, silt and clay ranging from 33 to 55%, 22 to 40% and 10 to 30% respectively. In the deeper horizons, sand was observed to reduce drastically to less than 23%, while clay increased to greater than 50%. The clay content is very high in the deeper horizons exceeding 35%. By implication, such soils with a very high clay content and plasticity index are considered as Vertisols, with a profound influence in the occurrence of landslides. The top soil predominantly contains more quartz, while subsurface horizons have considerable amounts of illite/muscovite as the dominant clay minerals, ranging from 43% to 47 %. The liquid limit, plasticity index, computed weighted plasticity index (PIw), expansiveness (ɛex) and dispersion ranging from 50, 22, 17, 10 and 23 to 66, 44,34,54 and 64, respectively also have strong implications for landslide occurrence. Landslides are not normally experienced during or immediately after extreme rainfall events but occur later in the rainfall season. By implication, this time lag in landslide occurrence and rainfall distribution, is due to the initial infiltration through quartz dominated upper soil layers, before illite/muscovite clays in the lower soil horizons get saturated. Whereas forest cover reduced from 40 % in 1985 to 8% in 2015, cultivated land and settlements increased from 16% and 11% to 52% and 25% respectively during the same period. The distribution of cultivated land decreased in lower slope sections within gradient group < 15˚ by 59%. It however increased in upper sections within gradient cluster 25˚ to 35˚ by over 85% during the study period. There is a shift of cultivated land to the steeper sensitive upper slope elements associated with landslides in the study area. More than 50% of the landslides are occurring on cultivated land, 20% on settlements while less than 15 % and 10% are occurring on grassland and forests with degraded areas respectively. Landslides in Kigezi highlands are triggered by a complex interaction of multiple- factors, including dynamic triggers and ground condition variables. Topographic hollows are convergence zones within the landscape where all the parameters interact to cause landslides. Topographic hollows are therefore potential and actual landslide sites in the study area. Characterized by deep soil horizons with high clay content dominated by illite/muscovite minerals in the sub soils and profile concave forms with moderately steep slopes, topographic hollows are the most vulnerable slope elements to landslide occurrence. The spatial temporal patterns of landslide occurrence in the study area has changed due to increased cultivation of steep middle and upper slopes. Characterized by deep soil horizons with high clay content dominated by illite/muscovite minerals in the sub soils and profile concave forms with moderately steep slopes, topographic hollows are the most vulnerable slope elements to landslide occurrence. The spatial-temporal patterns of landslide occurrence in the study area has changed due to increased cultivation of steep middle and upper slopes. A close spatial and temporal correlation between land use/cover changes and landslide occurrence is discernible. The understanding of these topographical, pedological and land use/cover parameters and their influence on landslide occurrence is important in land management. It is now possible to identify and predict actual and potential landslide zones, and also demarcate safer zones for community activities. The information generated about the area’s topographic, pedological and land cover characteristics should help in vulnerability mitigation and enhance community resilience to landslide hazards in this fragile highland ecosystem. This can be done through designating zones for community activities while avoiding potential landslide zones. It is also recommended that, tree cover restoration be done in the highlands and the farmers encouraged to re-establish terrace farming while avoiding cultivation of sensitive steep middle and upper slope sections.

- Description: The unique historical stressors linked to South Africa’s apartheid legacy, continues to manifest in the form of economic exclusion, social exclusion, inequality and poverty, with parents being subjugated to service users and extenders rather than included as service advocates, particularly in the child justice system. Furthermore, policies and practices do not include, engage and support parents on an intra and interpersonal level. Parents of children in conflict with the law, experience their children’s charge or arrest as well as their subsequent journey through the child justice system as a crisis resulting in their need for emotional, informational, practical and professional support during the child justice process. The similarities and differences between the contexts of child protection and child justice in supporting parents illuminates the existing gaps in child justice legislation, policy and practice resulting in a lack of support for parents during the child justice process. In the Children’s Act 38 of 2005, it is recognised that parents have a legal responsibility towards their children and that in fulfilling this responsibility parents can access support services to assist them when they face challenges in fulfilling this responsibility. In contrast, despite 80 percent of children in conflict with the law being released into parental care and parents expressing the need for support in fulfilling their parental responsibility, in this regard the Child Justice Act 75 of 2008 fails to make provision for parents to access support services. The child justice system’s narrow focus on parents as service extenders contributes to parents’ being excluded from targeted support services resulting in parents’ support needs not being addressed. The lack of programmes and services aimed at supporting parents highlight the need for coordinated services that address the multiple stressors parents are exposed to. To this end, this study was aimed at coconstructing a practice model for supporting parents of children in conflict with the law. The theoretical lenses employed in the current study namely; the Ecological systems model and the Buffering effect model describes the various systems parents need support from and the type of support they need from their family, community and professionals. Guided by a qualitative approach, the present study integrated applied research, in particular intervention design and development with participatory action research as it allowed systematic collaboration during the research process to ensure rigour. This study involved participants from two research sites namely, the Nerina One- Stop Child Justice Centre in Port Elizabeth and the Reception, Assessment and Referral office at the Uitenhage magistrates’ court. Employing a non-probability purposive sampling method, this study facilitated the participation of parents of children in conflict with the law and child justice officials who met the inclusion criteria, in the co-design and development of a practice model for supporting parents of children in conflict with the law. Participants assumed an expert and collaborative role, which enabled the co-construction of knowledge, meaning and innovation of the practice model. Qualitative data collection methods namely, twelve focus groups and thirty two participant observations, were used to explore, co-construct, describe and design a practice model for supporting parents of children in conflict with the law during the child justice process. Thematic analyses was employed to condense the data, search for codes, categories, themes, relationships and patterns in the data. Due to the research approach and design, data analysis was ongoing and informed design and development of the practice model. Based on the thematic analysis and synthesis both descriptive and analytic themes emerged. To ensure trustworthiness, this study employed various strategies to strengthen commitment, rigour, transparency and coherence. In addition, the participative research process, the inclusion of multiple forms of qualitative inquiry and the significance of the study contributed to the validity and quality of the study. Ethical considerations applicable to the study included participants’ voluntary participation, their informed consent and ensuring participants’ privacy or maintaining confidentially. Various strategies were employed to prevent or minimise risk to participants. The findings showed that formal sources of support, in particular, offer opportunities for parents to access individual and family counselling, parenting advice, and peer support. The study also highlighted the importance of recognising parents as a subsystem in the child justice system offers potential opportunities for inclusion of parents as co-facilitators of parenting programmes or support groups, as peer supporters during the child justice process. Parents’ inclusion as a partner in the child justice system is highlighted as an opportunity for parents to be able to vi participate in child justice fora, oversight committees and accreditation committees to influence policy, services and budget allocations for services to support parents of children in conflict with the law. This study’s contribution to the existing body of knowledge is an integrated, multidisciplinary, multi-phase co-constructed practice model that would enable inclusion of, and support for, parents of children in conflict with the law prior to, during and after the child justice. The co-constructed practice model (a) involves a continuum of parent-centred support for and inclusion of parents prior to, during and after the child justice process; (b) advances an inclusive and collaborative child justice system that views parents as important stakeholders in determining the type of services they need and being involved in developing practice; and (c) promotes parents as equal partners in decision making and policy making to influence legislation, policy and practice in the child justice system.

- Description: In order for the proceeds of unlawful activities to be completely dislodged from the criminals’ hands, the latter should be effectively deterred from allowing their assets to be used to execute or facilitate the commission of offences. When properly exacted, in the interests of justice and within the existing constitutional framework, the legal process known as asset forfeiture should ensure that crime never pays. Asset forfeiture refers to both criminal forfeiture, which is conviction based following the United Kingdom asset forfeiture regime and civil forfeiture, which is non-conviction based following the United States of America one.2 Chapter 5 provisions of the Prevention of Organised Crime Act3 (hereafter POCA) provides for court, Basdeo M – Search, Seizure and Asset Forfeiture in the South African Criminal Justice System: Drawing a Balance between Public Utility and Constitutional Rights (2013) LLD, University of South Africa in Chapter 5 where a comprehensive comparative study of SA POCA and United States of America’s asset forfeiture and origin is undertaken. 3 Act 121 of applications for a restraint, confiscation and realisation for the recovery of proceeds of unlawful activities. The restraint is invoked when a suspect is to be charged or has been charged or prosecuted, there are reasonable grounds to believe that a conviction may follow and that a confiscation order may be made. Chapter 6 provisions of POCA provide for court applications for preservation and forfeiture order targeting both the proceeds of unlawful activities and removal from public circulation of instruments or assets used in the commission of offences where the guilt of the wrongdoer is not relevant. POCA has a Schedule with 34 items setting out examples of offences in relation to which civil forfeiture may be invoked. When the State discharges this noble professed task in the name of public safety, security and crime combating, legal challenges arise. This is more so within a constitutional democratic context where both individual and property rights are enshrined and protected. This study deals with some of these challenges. To the mind of a legal researcher, the law of asset forfeiture is, in this process, moulded and developed. South Africa (a developing country), Canada and New Zealand (developed countries in the north and southern hemispheres) have constitutional democracies. They also have asset forfeiture regimes, which attracted the attention of the researcher. The question is: can the developing country learn some best practices from the developed countries in this particular field? It would be interesting to establish this and the level of development of this field in the three countries under study. South Africa, with no federal government, has nine Provinces, single asset forfeiture legislation5 (combining both criminal forfeiture i.e. restraint, confiscation and realisation applications and civil forfeiture i.e. preservation and forfeiture applications), and a criminal statute6 applicable to all such Provinces. It also has, like Canada and New Zealand, pockets of asset forfeiture provisions embedded in various statutes. There is only one asset forfeiture office under the umbrella of the National Prosecuting Authority.7 It has branches8 in the Provinces, invoking the provisions of POCA, since 1999. It is not part of the police department. The researcher joined the South African Port Elizabeth branch in March 2003, Bloemfontein, Kimberly and Mmabatho branches from 2010 to 2011, July 2012 onwards in the Port Elizabeth and has practical experience in this regard.

A comparative exposition of Islamic law relating to the law of husband and wife

- Description: Notwithstanding the enactment of the Constitution of the Republic of South Africa, 1996 the recognition of systems of religious, personal or family law for certain cultural and religious groups has either been limited or is virtually non-existent. To this extent, marriages concluded in terms of Islamic rites do not enjoy the same legal recognition that is accorded to civil and customary marriages. Non-recognition of Muslim marriages means there is no legal regulatory framework to enforce any of the consequences that arise as a result of the marriage, or any orders that are made by the Ulama, thereby creating a perilous situation that has dire consequences for spouses to a Muslim marriage. Despite South Africa’s commitment to the right of equality and freedom of religion, the courts have acknowledged that the failure to grant recognition to Muslim marriages on the ground of gender equality, has worsened the plight of women in these marriages, in that they were left without effective legal protection, should the union be dissolved either by death or divorce. Whilst the ad hoc recognition of certain consequences of Muslim marriages by the judiciary has gone a some way to redress the plight of Muslim women, and provided relief to the lived realities of Muslim women, these decisions are in fact contrary to the teachings and principles of Islam and therefore problematic for Muslims. These court decisions, that are in conflict with Muslim Personal Law (MPL), will ultimately lead to the emergence of a distorted set of laws relating to Muslim family law. This is a real cause for concern. This thesis is written from an Islamic legal theory perspective, which is contrary to western legal theory, as the latter adopts a human rights perspective. The basis of modern western democratic societies is a constitution that is premised on human rights and equality and which advocates the notion that the rights contained in the constitution reign supreme in all matters, religion included. Therefore, where a conflict arises in respect of the freedom of religion and the right to equality, western ideologies and philosophies dictate that the latter trump the former. This would inevitably mean that religious law would have to be adapted and ultimately amended so that it is in compliance with the constitution. From an Islamic religious perspective, this is not feasible and practicing Muslims will find this untenable. This may be legally uncomfortable in South Africa as a constitutional democracy but it is the reality for the adherents of the Muslim faith. A draft Muslim Marriages Bill (MMB) was released in 2003, and an amended MMB was tabled in Parliament in 2010. Both MMBs propose the legal recognition and regulation of Muslim marriages in South Africa. However, the two major issues delaying the enactment of the MMB into legislation are, firstly, whether or not the MMB would pass constitutional muster and secondly, the lack of agreement in the Muslim community on whether the MMB is Shari’ah compliant. Despite the largely consultative process that the MMBs underwent the legislative attempts to enact the MMB into legislation has not been successful. This thesis seeks to provide a possible solution whereby legislation regulating MPL law can be implemented in South Africa, notwithstanding the apparent conflict existing between MPL and the rights contained in the Bill of Rights. Notwithstanding the preference shown by the legislature to enact the MMB into legislation which will grant recognition to Muslim marriages, it is submitted there is a need for the legislature to rethink the approach that has to date been adopted. To this extent, it is submitted that the legislature should reconsider granting recognition to Muslim marriages by enacting legislation that takes the form of general legislation where state recognition is granted to all religious marriages, whether it be Muslim, Hindu or Jewish marriages. General legislation would mean that the state would require the marriage to be registered. However, the prescribed requirements, formalities and the consequences of the marriage would be determined by the chosen religious system of the spouses. On a national level a comparative analysis between Islamic law and the South African legal system, relating to the law of marriage is conducted. For the comparative analysis on an international level the law of marriage in England and Wales has been chosen. South Africa and England and Wales share a commitment to human rights and have adopted various approaches in respect of accommodating the application of Islamic law. Furthermore, an internal pluralism exists within the Muslim communities in South Africa, England and Wales as the majority of Muslims in these countries have to varying degrees developed diverse strategies to ensure compliance with Islamic law, and as well as South African and English law. The manner in which MPL is granted recognition needs to be given careful consideration as the implementation of this legislation will only be successful if it is compatible with the rulings and teachings of Islamic law. Caution should therefore be exercised to ensure that the fundamental aspects of MPL are not compromised as this will result in the legislation not being Shari’ah compliant and there will be no buyin from the Muslim community, with the consequence that this legislation will be mere paper law.

- Description: The Evolutionary Robotics (ER) process is a technique that applies evolutionary optimization algorithms to the task of automatically developing, or evolving, robotic control programs. These control programs, or simply controllers, are evolved in order to allow a robot to perform a required task. During the ER process, use is often made of robotic simulators to evaluate the performance of candidate controllers that are produced in the course of the controller evolution process. Such simulators accelerate and otherwise simplify the controller evolution process, as opposed to the more arduous process of evaluating controllers in the real world without use of simulation. To date, the vast majority of simulators that have been applied in ER are physics- based models which are constructed by taking into account the underlying physics governing the operation of the robotic system in question. An alternative approach to simulator implementation in ER is the usage of Artificial Neural Networks (ANNs) as simulators in the ER process. Such simulators are referred to as Simulator Neural Networks (SNNs). Previous studies have indicated that SNNs can successfully be used as an alter- native to physics-based simulators in the ER process on various robotic platforms. At the commencement of the current study it was not, however, known how this relatively new method of simulation would compare to traditional physics-based simulation approaches in ER. The study presented in this thesis thus endeavoured to quantitatively compare SNNs and physics-based models as simulators in the ER process. In order to con- duct this comparative study, both SNNs and physics simulators were constructed for the modelling of three different robotic platforms: a differentially-steered robot, a wheeled inverted pendulum robot and a hexapod robot. Each of these two types of simulation was then used in simulation-based evolution processes to evolve con- trollers for each robotic platform. During these controller evolution processes, the SNNs and physics models were compared in terms of their accuracy in making pre- dictions of robotic behaviour, their computational efficiency in arriving at these predictions, the human effort required to construct each simulator and, most im- portantly, the real-world performance of controllers evolved by making use of each simulator. The results obtained in this study illustrated experimentally that SNNs were, in the majority of cases, able to make more accurate predictions than the physics- based models and these SNNs were arguably simpler to construct than the physics simulators. Additionally, SNNs were also shown to be a computationally efficient alternative to physics-based simulators in ER and, again in the majority of cases, these SNNs were able to produce controllers which outperformed those evolved in the physics-based simulators, when these controllers were uploaded to the real-world robots. The results of this thesis thus suggest that SNNs are a viable alternative to more commonly-used physics simulators in ER and further investigation of the potential of this simulation technique appears warranted.

- Description: The increase in global rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) has had far reaching effects on healthcare services around the world. According to the 2017 statistics released by UNAIDS, South Africa has the largest HIV epidemic in the world. The South African Department of Health provides an HIV counselling and testing (HCT) service to patients in order that they may know their HIV status and endeavours to educate patients so that they may adapt their behaviours and lifestyles. The goal of this study is to develop a support programme for nurses to assist them in coping emotionally with their day-to-day activities when providing HCT services to patients attending primary healthcare clinics. The paradigm used as a lens to view the phenomenon is Kinlaw’s cyclical growth of empowerment theory. The researcher used a qualitative,explorative, descriptive and contextual design. The study involves three phases: (a) empirical research that explores nurses’ experiences of performing HCT in primary healthcare rural clinics, (b) the development of a conceptual framework for a support programme using the survey list of Dickoff et al. (1968:427). (c) the formalisation of the Comprehensive Support Programme to help nurses to cope emotionally with working with HCT on a long-term basis. Chinn and Kramer (2005118) were used to evaluate the programme. . The empirical findings revealed registered nurses experienced HCT both positively and negatively. They felt overwhelmed by the expectation that all patients attending primary healthcare clinics should be offered HCT routinely and the time constraints involved. They described how the emotional trauma attached to HCT affected their work patterns, leading to low productivity, and affected them outside work, leading to stress and sleep disturbances. They feltl disturbed that even when informed, people choose not to adopt safer sex practices and that how patients responded to a positive diagnosis cannot be predicted. Participants showed signs of stress, frustration, despair and sadness because most tested clients show positive test results and the number of clients testing positive is increasing. While participants felt helpless to improve the situation, at the same time, HCT was experienced as rewarding because it enabled diagnosis of medical conditions of which people weree not aware. The goal of the study was achieved with the development and formalisation of an extensive, relevant and applicable Comprehensive Support Programme for implementation for registered nurses to enable them cope emotionally when conducting HCT based on the empirical findings.

- Description: The devastation and destruction caused by natural and man-made disasters have become a global concern, particularly as such disasters affect the most vulnerable in society. The devastation they wreak frequently involves loss of lives and property. Globally, Disaster Management has moved in approach from reactive to proactive. Disaster management is now more than a field of study; it is the application of practices and principles which enable disasters to be managed both prior to and in the aftermath of their occurrence. Disaster risk management is the development approach to Disaster Management. The study addresses the integration of disaster risk management into integrated development planning at the local level in South Africa. The impact of disasters on social and economic development is of special interest. In many instances, resources that have been planned for development have to be diverted for response activities during disasters. Thus, development and disaster risk management are two sides of the same coin and should be dealt with in unison and not separately. There is also now widespread international acknowledgement for the idea of mainstreaming disaster risk management into development planning, particularly at the local level of government. The central argument of this study is that by integrating disaster risk management plans into integrated development plans at the local level, the risks faced by communities can be reduced. Risks can be even further reduced, and development enhanced when communities play an active role in disaster risk management. Within this context, the main objective of the study was to develop a model for integrating disaster risk management plans into integrated development plans at the local level. To achieve this key objective, the study used theoretical and empirical studies. The theoretical aspect focussed on international frameworks and national legislation for Disaster Management. Legislative requirements pertaining to the involvement of communities in integrated development planning were explored, as was the literature on asset-based community development. Empirical research complimented the theoretical research through the use of qualitative methods to collect data. This involved semi-structured interviews with eight government officials involved in provincial, district and municipal Disaster Management programmes, and focus group discussions with sixty ward committee members, so that community viewpoints would be included. The findings of the study reveal that the integration of disaster risk management plans into integrated development plans at the local level can greatly contribute towards reducing the risks faced by communities, especially high-risk communities. The study also revealed that by carefully considering and using community assets, local government could ameliorate the financial effects of Disaster Management and empower communities as first responders. The thesis gives an outline of a model that may be used by local government to integrate risks and community assets into an integrated development plan.

- Description: Organisational justice has captured the interest of scholars in recent years since it is associated with the perceptions and reactions of an individual, to the presence of fairness in an organisation. It thus captures what an individual feel or evaluates to be, morally correct rather than viewing it to be something prescriptive. This study was aimed at investigating the extent of organisational justice on organisational citizenship behaviour, ethical behaviour and employee retention in the South African financial services industry. A hypothetical model and measuring instrument was developed in order to investigate factors that may influence the organisational justice in the financial services industry. Six independent variables (trustworthiness of management, employee engagement, reward system, organisational transparency, two-way communication and organisational climate) were identified as variables that have the potential to influence organisational justice (mediating variable). It was also hypothesised that organisational justice) has the potential to affect the dependent variables (organisational citizenship behaviour, ethical behaviour and employee retention). Furthermore, nine null-hypotheses were developed to test the relationship between independent, mediating and dependent variables. All these variables were clearly defined and operationalised with various items that were obtained from other measuring instruments or self-developed items. A quantitative research approach followed. This study made use of the non-probability sampling technique, specifically convenient and judgemental sampling, as there is no data base of financial services firms available in South Africa. A purposive sample of 800 respondents was drawn from four provinces in South Africa. Factor and regression analyses were used to test the significance of the relationship between the various independent and dependent variables. The mediating variable of organisational justice was viewed by respondents as a two-dimensional construct, namely procedural-interactional justice and distributive justice. Consequently, intrinsic rewards, extrinsic rewards, organisational transparency and organisational climate were identified as independent variables that could have an impact on the procedural-interactional justice to predict organisational citizenship behaviour and reputable employee retention in the financial services industry. No relationships were identified between trustworthiness of management and employee engagement and procedural-interactional justice. The independent variables, trustworthiness of management, extrinsic rewards and organisational climate, could have an impact on distributive justice to predict organisational citizenship behaviour and reputable employee retention in the financial services industry. No relationships were identified between employee engagement, intrinsic rewards, organisational transparency and distributive justice. The findings of this study have contributed to the body of knowledge in the financial services literature in South Africa, by developing a theoretical model and a measuring instrument of organisational justice in the financial services industry. The antecedents of organisational justice in the financial services industry are not well documented in literature and findings of this study could thus contribute towards closing this gap in literature. The findings of this study could also inform policy formulation to assist with the implementation of organisational justice programmes in the financial services industry. This study provided useful and very practical guidelines to organisations in order to ensure the effective strategising and management of OJ that could enhance their local and global competitiveness and long-term survival.

- Description: The ocean economy has gained increasing economic significance over the past several years. Marine tourism as an economic activity has increased tremendously over the past several years. Not only does marine tourism and leisure have the ability to create employment, but there are numerous entrepreneurial opportunities in the industry. The importance of the coastal and marine tourism sector is evident and research in this sector abounds however, the issue of marine tourism education has been neglected as an area of research. A need therefore exists for the creation of ocean economy related qualifications and programmes and this study developed a curriculum framework for undergraduate coastal and marine tourism university programmes around which future Coastal and Marine Tourism (CMT) programmes could be created. The research objectives were to firstly determine the coastal and marine tourism stakeholders and role players’ perceptions and expectations of undergraduate coastal and marine tourism education and graduate competencies. The second objective was to ascertain the statutory and policy matters that shape university programmes and finally to incorporate the UNESCO-IBE curriculum framework into undergraduate coastal and marine tourism university programmes. This study fit within the pragmatic paradigm and a mixed methods research approach was utilised with a multiphase design. The data collection process was divided into three phases with Phase One collecting qualitative data through content analysis, Phase Two collecting quantitative data through a survey with questionnaire as research instrument and Phase Three collecting qualitative data through a semi-structured interview with an interview schedule as research instrument. Phase One included document analysis in order to determine the subsectors of the CMT industry, statutory and policy documents to determine programme development regulations as well as collected information regarding the socio-economic environment of the country. Phase Two collected data from industry operators and Phase Three collected data from educators and industry association representatives. The study identified four sub-sectors of the CMT industry namely Conservation Areas, Coastal and Marine Adventure Activities, Land-based Marine Tourism Attractions and Marine Resources and Recreation. All three phases of data collection were utilised to develop these four sub-sectors. The pertinent findings of Phase One indicate that the socio-economic environment in which the CMT programme would be developed is one with a slow economic growth rate, low numeracy and literacy levels with high numbers of unemployed graduates. Language policies are critical in order to accommodate English second language speakers. Furthermore, there are low levels of academics with doctoral degrees with targets to improve the status quo. Phase Two data collection notes that industry operators would prefer a programme that has strong practical and vocational focus with matters such as excursions, work-based learning and alternative teaching methods being important. These findings are supported during Phase Three data collection with educators and industry association representatives placing stronger focus on practical presentation of content and engagement with industry through site visits and demonstration of activities to students. Based on the findings in all three phases, a schematic of the CMT curriculum framework is developed and presented. Recommendations are made for the implementation of the CMT curriculum framework in order to identify omissions and to include the student voice. Stronger linkages should also be forged between industry and academia in order to facilitate the CMT programme. Further research could also test and implement the four identified sub-sectors in order to determine its suitability.

- Description: Recent years have seen the decline of entrepreneurial activity in South Africa. This is especially concerning in that, officially, 27.7% of South Africans are unemployed. The unofficial unemployment figures are closer to 50%. The South African economy is battling to recover from the world economic crisis of 2009/10, putting pressure on government to alleviate growing unemployment and curtail social unrest. Furthermore, a South African economy which thrives on entrepreneurial activity will become more competitive from a global perspective. The purpose of this study is to contribute to the promotion and development of entrepreneurship in South Africa, in an effort to combat the problems listed above. In order to achieve this purpose, the objective was to develop and test a model which could be used in the development of entrepreneurs. The rationale is that, if the factors which affect entrepreneurship could be identified and tested, then recommendations could be made which could promote the development of entrepreneurs in South Africa. The approach was as follows: Perform a literature review which would cover both global and local (South African) approaches to developmental training for entrepreneurs; Develop a theoretical model comprising of identified factors which formed the base for the data collection; Develop a measuring instrument to test the relationships described in the theoretical model empirically; • Empirically test the proposed model and suggested hypotheses by means of sourcing data from entrepreneurs in South Africa and statistically analyse the sourced data; Formulate the final theoretical model to support the research objectives; and Propose recommendations based on the results of the statistical analysis. The focus of the literature study was on two main areas: trends in global developmental training, and South African initiatives to stimulate developmental training of entrepreneurs. The literature on global entrepreneurial development highlights two distinct categories for entrepreneurial development: 1) entrepreneurial education and 2) entrepreneurial training. The literature study concerning South African methodologies for developmental training for entrepreneurs, focused on current methods employed and highlighted areas on which improvements should be concentrated. From the literature study on both global and South African developmental training methods, ten independent variables (entrepreneurial culture; socio-emotional attributes; acquiring business skills; industry experience; opportunity identification; regulatory barriers; economic barriers; outside advice; formal training and informal training were identified as factors affecting entrepreneurial developmental training. All the variables were hypothesised as they were perceived to influence significantly the dependent variables: perceived global success as an entrepreneur and perceived individual success as an entrepreneur. These factors, clearly defined and operationalised, were structured in a questionnaire which was sent randomly to South African business owners. Data were collected from 332 respondents and subjected to various statistical analysis techniques. Firstly, Exploratory Factor Analysis (EFA) was conducted to assess the discriminant validity of the research instrument. Secondly, Cronbach’s alpha coefficients were calculated for each of the identified factors to confirm the reliability of the research instrument. The significance of the hypothesised relationships in the revised model were then tested by using the statistical technique known as Structural Equation Modelling (SEM) This study contributed to this specific field of knowledge.

- Description: Physically disabled individuals face a number of challenges when carrying out their everyday activities such as moving around, communicating with others, and their personal care. One way of overcoming these challenges is by using personal assistants. An alternative is to enable independence through assistive technology. This research aimed to investigate how physically disabled individuals experience these challenges, and how assistive technology can enable them to be more independent. In order to achieve the goal of this research, existing literature was reviewed on disability, assisted living, and interaction techniques. The literature study on disability identified some of the challenges faced by disabled individuals in their daily lives. In order to contextualize these challenges, interview studies with eighteen disabled individuals, and twelve personal assistants were carried out in Kampala, Uganda and Port Elizabeth, South Africa. The participants from both Uganda and South Africa were limited to those living in urban areas. The Ugandan participants noted that, whereas technology may assist their daily lives, their most essential needs are basic disability support aids such as wheelchairs and better long canes. This was in contrast with the South African participants, who have access to basic disability support aids. The South African participants identified their key needs as controlling an electronic environment without assistance, e.g. house lights, using a mobile phone, and using a computer without assistance. The interviews narrowed down the scope to focus on individuals with quadriplegia, specifically individuals who have limited hand use, but can comfortably speak and move their heads, and make gestures such as head shake and nod. Literature on assisted living technologies and frameworks, provided the technical foundation for the research. The literature review of interaction techniques identified a number of possible ways in which individuals with quadriplegia can interact with technology. An appropriate set of interaction techniques, namely head shake and nod, voice, and facial feature tracking were identified. Evaluations of the interaction techniques excluded head shake and nod, because of an inconsistency in detecting an individual’s head pose in different lighting conditions, when using a Microsoft Kinect. Voice and facial feature tracking using a standard computer camera were identified as the most suitable interaction techniques for this study. A framework for designing assisted living software services was developed. The framework allows disability researchers and solution developers to understand the needs of a given disability group, and design relevant solutions. To demonstrate that the proposed framework iii | P a g e addresses the main aim of this research, a prototype was developed that enables users to control smart lights (Phillips hue), a Smart TV (Samsung), and carry out basic navigation and webbrowsing on a computer. Users could interact with the software using voice and facial feature commands. A usability study was carried out with fifteen physically disabled individuals in Port Elizabeth, South Africa. The results of the evaluation study were highly positive. The successful evaluation of the prototype provided empirical evidence that the proposed framework does assist in the design of relevant and useful software services, to meet the unique needs of physically disabled individuals.

- Description: Climate change and a speedily depreciating ecosystem are global challenges. These challenges are, in the main, attributed to activities in the construction industry, which relies heavily on the environment to provide materials. Studies show that the impact in developing countries is worse, due to the low level of awareness. Consequently, there is a dearth of research-based evidence on the ethics of sourcing of materials. This research aimed at changing that by investigating the ethics of materials sourcing in Nigeria. Epistemologically, the research is subjective and paradigmatically phenomenological. The methods used for data collection include a comprehensive literature review, collection of archival records, empirical studies of sixteen organisations that are involved in materials sourcing, transportation and production of eight construction materials across the six geo-political zones in Nigeria, that were purposefully selected. The findings reveal that the majority of the processes employed to source, transport and produce materials for the construction industry are not ethical environmentally due to their contribution to air pollution, water pollution, noise pollution and vibration, landscape damage, harm to flora and fauna and waste production. Furthermore, the study found that the majority of the organisations studied, do not produce sustainability reports for their operations. The study developed a framework for ethical sourcing of construction materials. The study recommends that organisations should utilise the framework developed in this study to enhance their sustainability practices.

- Description: The construction sector is known for its poor health and safety (H&S) record. This situation contributes to the poor performance of construction projects and poor worker productivity. In view of this, the research was undertaken to improve workers’ H&S practices. This study determined how the systems thinking approach will mitigate unhealthy and unsafe construction practices in Lagos, Nigeria by developing interventions, and proposing a model for improved H&S practices. The study utilised a mixed research method approach. Both quantitative and qualitative methods were used specifically the concurrent embedded method to obtain and analyse the data. The sample size for the quantitative study was 375 respondents and a total of 40 respondents were engaged in the qualitative study. The sample consisted of designers, contractors, clients, quantity surveyors, project managers, construction managers, supervisors, and construction workers (masons, carpenters, painters, roofers, electricians) based in Lagos, Nigeria. The findings reveal that there is inadequate consideration for H&S during the procurement of construction projects. Furthermore, the absence of H&S regulations relating to the construction sector was observed. Unsafe practices at construction sites in Nigeria can be attributed to this discovery. The study reveals that the regulatory system, the organisation, the individual and the work environment all have an impact on H&S work practices. Although the contractors are mainly responsible for H&S at construction sites, other construction stakeholders (such as clients, consultants, etc.) influence H&S practices. The findings highlight the need for the adoption of a holistic approach to facilitate improvement in H&S practices on construction sites. The research has contributed to the body of knowledge by developing a framework for improving workers’ H&S performance on construction sites.
