  • Description: The identification of discrete self-sustaining productive units in marine populations is essential for achieving sustainable fisheries objectives. Marine fish populations frequently exhibit dynamic characteristics across their life-histories, displaying variability in spatial structure and mixing patterns, both within and among populations. The incoherent application of management boundaries on biological populations can bias stock assessment results and have important implications on sustainable fisheries management. Patagonian toothfish (Dissostichus eleginoides) is a long-lived, slow-growing, late-maturing, deep-sea, benthopelagic species. It forms the basis of important and highly lucrative industrial and artisanal fisheries across its distribution. Patagonian toothfish have complex life-histories characterised by high dispersal potential during the egg and larval phase, a wide depth range because of their ontogenetic migratory behaviour, and large adult size that is capable of undertaking long-distance active movements (>200 km). These characteristics provide opportunities for high levels of connectivity, and as such, the stock structure is not well understood. We applied an integrated, multidisciplinary approach to provide an improved understanding of the complex stock structure dynamics for Patagonian toothfish on the Patagonian Shelf, specifically in relation to the shelf, slope, and deep-sea plains around the Falkland Islands. Research results were focused on aspects pertaining to (1) geographic variation in phenotypic characters (otolith shape); (2) a description of the spatial-temporal distribution patterns; (3) the active movements of deep-sea adults (tag-recapture study); and (4) the identification of early life-history dispersal through otolith microstructure and microchemical chronologies. Results from the study indicate high regional connectivity during the early life-history stages derived from at least two spawning contingents into spatially discrete nursery areas (cohort groups) on the Falklands Shelf. Fish followed distinct ontogenetic pathways into deeper waters adjacent to the areas wherein juvenile settlement into a demersal habitat occurred. There is little to no evidence of mixing among cohort groups during their ontogenetic migration into deep-sea adult habitats, reflecting a mixed population based on oceanographically defined egg and larval dispersal. The majority of the adult component of the population continue to display high site fidelity. However, between 9 and 25% of the population, consisting predominantly of larger reproductively capable adults undertake long-distance dispersal behaviour, identified as home-range relocations from the adult deep-sea habitats towards three of the known southern spawning grounds in the region. Results are suggestive of a requirement for improved collaborative efforts for regionally-based management approaches with careful consideration of local stock contingents. Future monitoring and research priorities should focus on the identification of reproductive potential, dispersal pathways and settlement patterns of stock contingents to inform the dynamics of mixed stock origins across the Patagonian region. While many aspects regarding the stock structure remain unresolved, results derived from the current studies can be used to inform the development of management measures to ensure the continued recovery and sustainable management of Patagonian toothfish within the region. , Thesis (PhD) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

  • Description: The research probes the impact of succession politics on state administration in Africa, Zimbabwe as a case study. Power transition in any political landscape promotes the regeneration and configuration of the political architecture and the functionality of the administrative apparatus of the state. Government performance may thus be viewed as a result of political processes and dynamics that influence governance in a polity. Political succession determines the composition of administrative organs of the state and many political leaders wish to work with administrative apparatus, which are compatible with their ideological orientation. Regular transfer of executive power is the major test of stability, legitimacy and maturity of a nation’s political system, but in Zimbabwe, political leaders have shown a consistent trajectory of violating or amending state and party constitutions to prolong their stay in power (Constitutional coup or a third term tragedy). This has been compelled by ruthless silencing of dissent by suffocating political activism culminating in strong personalities and weak institutions. Succession politics in Zimbabwe resembles executive dominance, egocentrism, excessive appointing powers which are compounded by lack of institutional framework for succession. This undermines the professional independence of the bureaucracy, which in turn inhibits the pursuit of sound governance. Therefore, passing the baton to the next leader has been a challenge; resulting in the personalization of, governments and political parties by leaders. While constitutions provide for elective congress for purposes of electing party leadership and/ or renewing their mandates, there is strong literature pointing to the capture of representative institutions such as Parliaments through strong normative values by leaders. This erodes the role of Parliaments or congresses as a democratic institution, as leaders have used it to “endorse” themselves. The research examines the influence of succession politics on state administration, especially on how the institution of the state and party politics in Zimbabwe conflate with the public administration system leading to state malfunction. This research adopts a qualitative research design that provides an understanding of underlying reasons, opinions, and motivations on political succession and state administration in Zimbabwe. Data was collected through in-depth interviews, complemented by document review and analyzed through thematic content analysis. The study found out that, despite the existence of the legal frameworks that promote seamless power transition, political, societal and historical factors exacerbate Zimbabwe’s succession dilemma. Colonial legacy, societal laxity, the military factor, capture of state institutions by the political elite, lack of a retirement institutional mechanism, the principle of sovereignty and politicization of the succession process were found as the major hindrances to Zimbabwe’s succession trajectory. It recommends broad based and genuine civil service, electoral, security and political (politics with ethics and values) reforms to dismantle the current legacy imbedded in the political system. , Thesis (PhD) (Public Administration) -- University of Fort Hare, 2021

  • Description: Leisure-time physical activity (LTPA) is an important contributor to total physical activity and the focus of many interventions promoting activity in high-income populations. Little is known about LTPA in subSaharan Africa (SSA), and with expected declines in physical activity due to rapid urbanisation and lifestyle changes we aimed to assess the sociodemographic differences in the prevalence of LTPA in the adult populations of this region to identify potential barriers for equitable participation. A two-step individual participant data meta-analysis was conducted using data collected in SSA through 10 population health surveys that included the Global Physical Activity Questionnaire. For each sociodemographic characteristic, the pooled adjusted prevalence and risk ratios (RRs) for participation in LTPA were calculated using the random effects method. Between-study heterogeneity was explored through meta-regression analyses and tests for interaction. Across the 10 populations (N = 26,022), 18.9% (95%CI: 14.3, 24.1; I2 = 99.0%) of adults (≥ 18 years) participated in LTPA. Men were more likely to participate in LTPA compared with women (RR for women: 0.43; 95%CI: 0.32, 0.60; P less than 0.001; I2 = 97.5%), while age was inversely associated with participation. Higher levels of education were associated with increased LTPA participation (RR: 1.30; 95%CI: 1.09, 1.55; P = 0.004; I2 = 98.1%), with those living in rural areas or self-employed less likely to participate in LTPA. These associations remained after adjusting for time spent physically active at work or through active travel. In these populations, participation in LTPA was low, and strongly associated with sex, age, education, self-employment and urban residence. Identifying the potential barriers that reduce participation in these groups is necessary to enable equitable access to the health and social benefits associated with LTPA.

  • Description: Electronic Medical Record (EMR) systems have been identified as having the potential to improve health care and allow the health care sector to reap a number of benefits when implemented successfully. These benefits include enabling quick and easy access to patient files and also reducing the problem of misplaced or lost patient files. Such EMRs allow for patient records to be up to date, provided that health care practitioners capture standard and consistent data in the relevant fields. In Africa, there are only a few countries that have successfully implemented EMR systems due to social and technological challenges. Social factors include lack of computer skilled health workers, lack of adequate training, physician’s resistance to shift from using paper records to electronic records, either due to complex systems or the fear of being replaced by the systems. On the other hand, the technological factors include lack of Information Technology (IT) and clinical resources, lack of internet access, financial barriers to purchase the necessary technological hardware and implementation costs. A few South African health care institutions have implemented EMR systems, however, most of the public health care facilities still make use of a manual system to capture patient information. In the case where public health care facilities do have an EMR system implemented, there are problems with the consistency of the data that is captured. The inconsistency is caused by the different understandings that the health care professionals have regarding the importance of capturing the necessary information that is collected at various points in health care institutions, thus affecting data quality. For the successful implementation and use of EMR systems, everything within the health care organisation should be integrated. In other words, the steering committee and workgroup, the equipment, the product, the processes, the system and the facility design and construction should be incorporated to work together. The common problems identified in literature regarding data quality in EMRs include misspelled words, inconsistent word strings, inaccurate information entered on the record and incompleteness of the record. These problems lead to poor quality information, lack of accessibility of the record, poorly organised notes and inaccurate information about the patient. The South African strategy aims to implement a National Health Insurance (NHI) which will provide citizens with equitable access to health care. For the successful implementation of the NHI strategy, South African health care sectors should address the barriers which were identified and learn from other African countries that have successfully implemented EMR systems and had positive outcomes. Therefore, this study investigates how data quality can be improved on electronic medical records in public health care in South Africa? The qualitative research methodology approach was used for this study. Interviews were conducted with eight health care professionals at Klerksdorp, in the North West province to obtain data regarding the factors they would deem important for the improvement of data quality in EMRs. The Data Quality Framework (DQF) was applied in this study and six dimensions were identified as the factors to improve data quality. These dimensions include completeness, accuracy, consistency, conformity, timeliness, and integrity. From the analysis of the interview responses, it was discovered that there were, in fact, data quality issues experienced at the public health care facilities of South Africa. A need was identified for the use of data quality assessment tools and solutions to address the data quality issues or challenges that health care practitioners are faced with during their daily jobs. Seven barriers were also identified as having an impact on the successful implementation of EMRs at health care institutions. These barriers, together with the data quality issues, influence the successful use of EMRs and should not be overlooked. From these barriers the study developed seven Critical Success Factors which can be used by the National Department of Health to improve the quality of EMRs. , Thesis (MCom) -- Faculty of Management and Commerce, 2019

  • Description: In South Africa there is pressure to deliver green building due to environmental issues such as climate changes, the energy crisis, as well as persistent water shortages. Although awareness and promotional effort have increased drastically concerning the adoption of green buildings, the South African design and construction industry is still lagging due to the conservativeness and slow rate of change in the construction industry. While enablers / facilitators have been recognised as opportunities to advance green building development, the South African built environment has not extensively explored the various possibilities to initiate enablers / facilitating conditions to enhance the adoption of green building. This study therefore investigates the critical factors impeding the adoption of green building and to explore the economic and non-economic facilitators / enablers regarded as the most important to stimulate stakeholders’ behavioural intentions to adopt green building. After an extensive review of literature with respect to barriers and factors that engender green building adoption, coupled with theoretical arguments relating change agents to construction innovation and sustainability theory, an exhaustive mixed-mode research approach was adopted. The sampling frame for the study was limited to four provinces, namely the Eastern Cape, Gauteng, Kwazulu–Natal, and Western Cape, given that 99% of the green building accredited professionals registered with the GBCSA are from these four provinces. The quantitative data was analysed using descriptive and inferential statistics, namely paired sample test, ANOVA test, Factor Analysis (FA), and logistic regression analysis (LRA). The qualitative data obtained across individual cases by means of a semi-structured interview was analysed using content analysis. In total, 106 professionals participated in the survey, and three respondents indicated their willingness and availability to be interviewed, hence three case studies were conducted. The results emanating from the study, inter-alia, indicate that the factors constraining the adoption of green building are categorised as: lack of information and incentives; inadequate skilled professionals; behavioural barriers; regulatory and steering factors, and the cost of green building. The results also indicate that green building consultants and environmental groups are classified as ‘innovators’, whilst architects are ‘early adopters’. However, government; municipalities, and general contractors are characterised as ‘late majority’. It was also evident from the empirical findings that the key attributes of adopters that encourage the adoption of green building were classified as: qualities of consultant team and contractor, and developers / clients’ experience. The perceived benefits of green buildings emanating from the findings were categorised as socio-economic, financial, and health and community benefits. The enablers that engender the adoption of green building were also categorised as: extended knowledge base and technical capacity; research and training of professionals; green lending incentives; progressive green building policy; economic incentives, and reward scheme and technical assistance. Two models have been developed using logistic regression model (LRM), model one (1) examined the predictable effect of economic and non-economic factors on the intention to adopt green building, whereas model two (2) examined the likelihood of the extent of green building adoption. The LRM results revealed five predictors and two control variables made a unique statistically significant contribution to model 1. The strongest predictor to enhance the intention to adopt green building was financial benefit (FB), recording an odds ratio of 9.1, which indicates that the likelihood to adopt is approximately 9.1 times more if financial benefits is evident. With respect to Model two (2), the LRM results showed that only two of the independent variables and three control variables contributed significantly to the model. The strongest predictor that determines the extent of adoption of green building was research and training of professionals (RTP), with odd ratio equal to 2.9. In effect, to engender the adoption of green building within the South African built environment, there is the need for an integrated and holistic approach forecasting on the importance of economic and non-economic enablers / facilitators in enhancing decision to adopt green building.

  • Description: This Thesis examines the state of constitutionalism in Uganda between 1962 and 2018. The central question which it seeks to answer is: ‘why did Ugandan governments persistently fail to adhere to the basic requirements of the doctrine of constitutionalism between 1962 and 2018?’ In answering this question, which has challenged and continues to challenge many academicians, politicians, government officials, researchers and the international community alike, the Thesis adopts the Theory of Neo-patrimonialism as a theoretical lens through which the behaviours of the post-independence presidents of Uganda are examined. The Thesis discovers that, indeed, Neo-patrimonialism is a fundamental framework for analysing and explaining constitutionalism in post-independence Uganda. Against this backdrop, the Thesis concludes that, the collective behaviours of Uganda’s post-independence presidents viewed through the lens of neo-patrimonialism are more fundamental in understanding the failure of democracy and good governance in Uganda than the country’s structural problems of constitutionalism. The originality of the Thesis is in: (a) its being the first comprehensive investigation into why Ugandan governments have persistently failed to adhere to the basic requirements of the doctrine of constitutionalism for the entire period of 56 years (1962-2018) of post-independence Uganda; and (b) its being the first study to apply the Theory of Neo-patrimonialism in explaining the volatile nature and state of constitutionalism in Uganda. The contribution of the Thesis to the existing knowledge lies in its; (a) generation of detailed and well-researched information about the volatility of constitutionalism in Uganda between 1962 and 2018, (b) recommendation of strategies that should be adopted to effectively enhance consititutionalism in Uganda, and (c) authentication of the validity of the claims that despite its shortcomings, Neo-patrimonialism is a Theory which not only continues to define and drive African politics but its application can suitably be used to explain the volatile nature of constitutionalism in post-independence Uganda and the rest of Africa.

  • Description: This thesis presents novel asymmetrical and symmetrical lanthanide phthalocyanines (Pcs) characterized using a number techniques including proton nuclear magnetic resonance, electron spin resonance, time correlated single photon counting, FTIR spectrometry, MALDI-TOF mass spectrometry, UV-Vis spectrometry, Raman spectroscopy and CHNS elemental analysis. The design of theses lanthanide Pcs takes the form of mononuclear, binuclear, trinuclear, bis- and tris(phthalocyanines). Nanomaterials such as zinc oxide nanoparticles (ZnO NPs), multi-walled carbon nanotubes (MWCNTs) and graphene oxide nanosheets (GONS) (oxidized and reduced) were employed for covalent linkage to mono- and binuclear phthalocyanines as conjugates. Transmission electron microscopy was used to characterize ZnO NPs, MWCNTs and GONS alone and when linked to lanthanide Pcs. Lanthanide Pcs alone and when linked to ZnO NPs, MWCNTs and GONS where embedded in polymers such as poly (methyl methacrylate) (PMMA), poly (bisphenol A carbonate) (PBC) and poly (acrylic acid) (PAA) for thin film preparation. The thickness of the thin films was determined by utilization of the knife edge attachment of the A Bruker D8 Discover X-ray diffraction (XRD). Optical limiting properties of lanthanide Pcs alone and as conjugates in solution and when incorporated into polymers were determined by employing a Z-scan technique. It emerged that low symmetry lanthanide Pcs (19, 20 and 21), the blue forms of bis(phthalocyanines) (only in solution; 24 and 28) as well as tris(phthalocyanines) (30 and 31) exhibit low limiting threshold (Ilim) values in solution and thin films (particularly PBC and PAA). The low limiting threshold values make these lanthanide Pcs reliable optical limiters.

  • Description: South Africa is a country where those who were oppressed in the past are trying to live in a society with their former oppressors. The youth of today appear to be carrying the anger, fears and uncertainties of the past. This could be the result of intergenerational transmission of prejudice, whereby memories of experiences, fears, anger and levels of anxiety may be absorbed by the next generation. The purpose of this study was to develop and implement an intervention programme that could assist adolescent learners in making their own informed decisions, despite the influences of the intergenerational transmission of prejudice. This was achieved by combining three theories, namely the transgenerational theory, historical trauma and social learning theory, with the principles of bibliotherapy. The research conducted was based in the interpretive paradigm, with the study methodology being qualitative in nature. The research design implemented was a case study. Data generation was achieved by utilising a variety of methods, namely open-ended questions, small focus groups and reflection journals. Analysis of the data was accomplished by applying a thematic analysis approach. The sample for this study was selected from a local, government high school and the participants consisted of a group of Grade 10 learners, who all held leadership positions in the school. The purpose of this study was achieved by utilising the principles of bibliotherapy to inform a programme to develop awareness of intergenerational transmission of prejudice. This was then combined with the principles of bibliotherapy, with scenarios taken from the animated film, The Land Before Time, to further assist in creating awareness and a better understanding of the intergenerational transmission of knowledge. Finally, the programme was used to equip the participants with the tools needed, to transfer what they had learnt from the programme to decisions they would need to make in their daily lives. This study has shown that the principles of bibliotherapy can be used to promote and develop awareness of intergenerational transmission of prejudice in adolescent learners.

  • Description: In the recent years, majority of African countries have been faced by conflicts during election periods. Some of the electoral related conflicts escalated into violence, and they have been transformed or managed. While other electoral related conflicts have just been prevented during the election periods but remain latent conflicts that would escalate triggered by future elections. This study focuses specifically on electoral conflicts in Kenya and its conflict management perspective from 2002-2013. To transform and manage the conflict, peacebuilding initiatives have been integrated in the study. The prime actors in Kenya electoral conflict includes the; the ruling party coalition, the leading opposition coalition and ethnic groupings affiliated to the ruling party and opposition. Other peripheral actors include: the Independent, Electoral and Boundary Commission (IEBC), the International Criminal Court (ICC) and the judiciary. Triangulation (the combination of two or more methods of collecting and analysing data) has been adopted both in data collection and analysis. Focus group interviews, selected individual interviews, and literature reviews were used to collect data, while research findings were analysed systematically using the constructivist grounded theory. Moreover, the liberal peace theory, Institutionalisation before Liberalisation (IBL) and findings from other researchers like (Elder, Stigant and Claes 2014:1-20), and the Afrobarometer research findings (Kivuva 2015) have been used to authenticate the research findings. Research findings indicates that claims of election rigging, numerous institutional failures, negative ethnicity and economic disparity, among other factors heighten the fear and anxiety that escalates during elections. Towards achieving peacebuilding and sustainable peace, the following reforms were undertaken: constitutional changes and reviews, electoral body reform, judicial reform, pursuit of transitional justice, extensive range of local initiatives reforms and police reforms. However, findings in the study also reveal that despite the latter reforms, peacebuilding measures have been short-term, temporal, and not fully successful, leaving behind a latent conflict that could be triggered again with future electoral conflicts. Besides that, negotiation, dialogue and mediation played a role in restoring trust and confidence in the democratic structures after escalated elections. We also recommend that multi-ethnic composition for electoral coalitions should also be adopted as a means to mitigate ethnic triggered conflicts.

  • Description: The main aim of the study was to explore the effects of domestic violence in the psychosocial development of children at Mlungisi Township, Chris Hani District in Queenstown – Eastern Cape Province. The specific objectives of the study were: to investigate the effect domestic violence has on the psychosocial development of children; to assess the behavior of the children subjected to domestic violence; and to examine challenges that children are facing due to domestic violence; and to examine the support provided by professionals (Social works, community worker, educator, South African Police and Justice System) to children who are victims of domestic violence. The study adopted a qualitative research paradigm and non-probability sampling methodology in the form of purposive sampling technique. The study‟s sample size comprised of 20 participants, 7 male children between the ages of 9 and 16, and 8 female children between the ages of 9 and 16 on in-depth one-on-one interviews. Five children withdrew from the study because they became emotional and were reluctant to participate. The study also comprised of 5 participants in a focus group which composed of various professionals from government departments such as: Department of Social Development, Department of Education, South African Police Services, Lukhanji Municipality and Justice Official who are directly working with children. The research instrument used was an interview guide with open ended questions. The study findings include the following: effects of domestic violence on the psychosocial development of children; challenges faced by children due to domestic violence; behaviors of children subjected to domestic violence; support services; efficiency and effectiveness of services rendered to the children; and improvement of services rendered to the victims by government officials. The study recommendations were: more studies on domestic violence specifically on children as victims should be done; policy regarding domestic violence needs to be reviewed and in order to accommodate children; there should be policies that focus solemnly to children who happen to be victims of domestic violence not domestic violence in general; and government departments and other relevant stakeholder should be strengthened or even develop new intervention strategies to ensure effectiveness in curbing domestic violence.

  • Description: This mini-dissertation, aims to review tribal armed conflict resolution in selected Counties in Lakes State, South Sudan. The objectives of the study were to find out the consequences of the tribal armed conflicts on governance and service delivery and strategies to mitigate peace and tribal armed conflict resolution in order to enable development in the selected counties of Lakes state. Quantitative and qualitative data was collected from a sample of three hundred and ten (310) respondents who included the County Commissioners, Judges and Magistrates, Law enforcement officers, local government officers and traditional leaders through questionnaires and interviews. The study sought to review the effects of tribal armed conflicts on service delivery in the selected communities. It further examined conflict resolutions mechanisms and strategies that have been used by various actors and stakeholder to ameliorate tribal armed conflict in Lakes State, South Sudan. The results of the study showed that ethnicity in conflicts in South Sudan has played a significant role and has posed many challenges to scholars, political leaders, appointed public officials and communities alike. Some of the challenges include; tribalism, ethnic conflicts, and struggle over scarce resources. This has often led to rampant underdevelopment, under-representation in governance; unemployment and poverty, among administrative perils and dysfunctions that have subsequently been major drivers of tribal armed conflicts. Many youth who are unemployed are often involved in cattle raiding, hence revenge attacks often lead to frequent tribal armed conflicts. The study recommends that effective and sustainable peace building can be achieved through empowerment of the communities and use of traditional strategies in tribal armed conflict resolution in Lakes State. This is because external players often attempt to engage in peace building activities without seeking sustainable solutions at the grassroots level. Very often conflict resolution has been the preserve of NGOs and diplomats, who have no intimate acquaintance with local contexts. The study suggests that provision of services to the people through sustainable development of the rural areas and through the creation of alternative forms of livelihood, such as jobs, has to engage with and include the youth in economic development, so that tribal armed conflicts are ameliorated.

  • Description: African Potato (Hypoxis hemerocallidea), (AP) is an African traditional medicine (TM) that is commonly used for various nutritional/medicinal purposes and also by people infected with the human immuno deficiency virus HIV and AIDS patients as an immune booster. The use of AP has also been recommended by the former Minister of Health of South Africa for use by HIV positive people. The main phytochemical component of AP is a norlignan glucoside, hypoxoside, and other relatively minor components have also been reported. A recent in vitro study reported the effects of AP extracts, hypoxoside and rooperol (the metabolite of hypoxoside) on human metabolic enzymes such as the cytochrome P450 (CYP450) group of enzymes and also on the transporter protein, p-glycoprotein (P-gp). This research focussed on investigating the clinical significance of those in vitro effects on the pharmacokinetics of efavirenz (EFV) in humans. EFV was chosen as the substrate drug because it is in first-line regimen of treatment of HIV/AIDS in South Africa, and also has been reported to be a substrate for the specific CYP isozymes, 3A4 and 2B6, in common with APs metabolic involvement with 3A4. A high performance liquid chromatography method with ultra-violet detection (HPLC-UV) for the quantitative determination of EFV in plasma was developed and successfully validated according to international standards with good reproducibility, accuracy, recovery, linear response and requisite sensitivity. The preparation of the plasma samples for analysis was effected by using a simple and rapid precipitation method, and the mobile phase consisted of readily available solvents. EFV in plasma samples was found to be stable under the relevant storage conditions studied. The oral dose of AP, administered as a freshly prepared traditional decoction, was standardised based on the hypoxoside content, and the quality of all the AP decoctions was analysed immediately prior to administration, using a validated HPLC-UV method. A single dose, two-phase sequential study was conducted over a period of 31 days in 10 healthy volunteers. The clinical study was approved by the Rhodes University Ethical Standards Committee, and all the participants agreed to the conditions of the study by giving their informed consent. On day 1 of the study, human subjects were administered a 600 mg EFV tablet and blood samples were collected before dosing and at various intervals over a period of 48 hr post dosing. From day 16, a traditionally prepared AP decoction was administered daily at a standardized dose of 15 mg/kg/day per subject until day 30. On day 29, volunteers were administered a single 600 mg dose of EFV as was done on day 1. Plasma samples were harvested immediately after blood sample collection and frozen at -80 ºC until assayed. Geometric mean ratios of relevant pharmacokinetic parameters, Cmax (maximum plasma concentration achieved following dosing) and AUC0-48 (area under the curve of a plot of drug plasma concentrations versus time representing the extent of absorption) of EFV before and after co-administration of 14 successive daily doses of AP were compared and evaluated to determine whether an interaction had occurred. All subjects completed the study and the geometric mean ratios of Cmax and AUC0-48 were 97.30 and 102.82 with corresponding 90% confidence intervals (CIs) of 78.81-120.14% and 89.04-118.80%, respectively. Whereas the acceptance criteria for the ratios of the AUCs fell within the preset 90% CIs indicating no interaction, the Cmax ratios fell outside the limits. Although the protocol was developed in accordance with the United States of America Food & Drug Administration’s Guidance for Drug Interactions, a priori stating that both criteria need to fall within the acceptance limits to indicate no interaction, an argument is presented to waive the Cmax requirement for the declaration of an interaction. As a result, the pharmacokinetic data generated during this study indicated that the effect of AP on the pharmacokinetics of EFV is not clinically significant. Hence, co-administration of AP is unlikely to affect the clinical use of EFV. In summary the objectives of this project were: 1. To develop and validate a suitable HPLC-UV method for the quantitative determination of EFV in plasma. 2. To perform a mini-validation of the determination of hypoxoside for use as a marker in the quality control and standardisation of AP decoctions. 3. To conduct a clinical interaction study in order to determine whether AP affects the pharmacokinetics of EFV following concurrent administration. 4. To apply the validated HPLC-UV method to determine plasma concentrations of EFV in plasma of human subjects. 5. To use appropriate statistical methods and treatments such as a non-compartmental pharmacokinetic analysis to determine the occurrence of an interaction.

An evaluation of the questions posed to child witnesses in court to determine whether they are developmentally appropriate

  • Description: Children are often required to testify viva voce in criminal trials. The question arises whether children understand what is communicated to them during their testimony in court. In the courtroom, the witness serves as a source of information. In child abuse cases in particular, the meaningful participation of the child in court proceedings is crucial due to the fact that the child is often the key witness, or the only witness, for the prosecution. The proper evaluation of the child’s evidence, however, requires that all role-players involved in the judicial process have a sound knowledge of those aspects which deal with child psychology, especially the cognitive and language abilities of children who testify. The procedure that is followed in court is not understood by the ordinary lay person, even less by children, and the language used is formalistic and very specialized. Legal language in general often contains cognitively and linguistically inappropriate questions which prevent children from relating their stories. Furthermore their responses do not sufficiently reflect their knowledge and experience of the incident of alleged sexual assault. Court language creates serious problems for children and accordingly prevents them from being effective witnesses and taking part in the judicial process in a meaningful way. The researcher, in her capacity as a Regional Court Magistrate, realized that children have limited understanding of the criminal trial process and often become secondary victims as a result of a system that does not acknowledge their cognitive and linguistic developmental levels. The purpose of this research was therefore to test the validity of the following hypotheses: • During the examination of children in a criminal trial developmentally and linguistically inappropriate questions are posed to them; and This results in ineffective communication. Eight court transcripts of criminal cases heard in the regional courts of the Eastern Cape and Mpumalanga by different presiding officers were chosen at random. These transcripts were analyzed and evaluated in order to determine whether questions posed to children when they testify are cognitively and linguistically appropriate. Each question in each of the eight transcripts was numbered and analyzed. The findings of the analysis were categorized in terms of whether they were cognitively and linguistically inappropriate questions. It was clear that the majority of questions put to the child witnesses were cognitively and linguistically inappropriate. It is evident from the evaluation that the manner in which the children’s evidence in court was presented and the way in which they were questioned created a communication barrier which placed a distorted version of events before the court. It is therefore recommended that full account be taken of the cognitive and language capabilities of each particular child in order to elicit reliable information during the child’s testimony. It is of the utmost importance that questioning be conducted in such a fashion so as to ensure that the child witness understands not only the content of the questions, but also what answers or responses are expected from them. At present, acknowledgement of linguistic and cognitive developmental appropriateness, concern and comprehension for the psychology of the child witness are ignored at best, and totally exploited at worst. This lack of knowledge about child development impacts adversely upon the child’s credibility in court. To elevate and enhance the credibility of children, it is of the utmost importance for society in general and court role-players in particular to appreciate the various stages and faces of child development. The main recommendation is that court role-players should make a paradigm shift and children, including victims of sexual assault, should be given the opportunity to tell their own stories in their own language supported by other methods of communication. In evaluating any possible changes, it is necessary to adopt and develop a holistic and multi-disciplinary approach based on scientific principles. A specialized system is required to deal with children in the criminal justice system and innovative methods to achieve this are necessary. There is a strong need to change or adjust the present manner in which the criminal justice system accommodates child witnesses. Such a change or adjustment will be in the best interests of children as envisaged in section 28 of the Constitution of the Republic of South Africa Act.

  • Description: Traditional views on International Relations dominate regional analyses. These invariably emphasize the dominance of state and market forces in inter-state relations. Experiences and expectations of people are less prominent in these discourses, and the practices they foster. This thesis critically analyses the regional processes in West and southern Africa within the framework of Critical Theory. It argues that these processes are constrained by instability and the increasing legitimacy crises of the State. The thesis demonstrates that the State, through exclusive nationalist practices, hinder the growth of a cosmopolitan order, and it argues that neo-liberal regionalism is a contested phenomenon because of its exclusive nature. Finally, the thesis suggests steps needed to resolve the legitimacy crises and to build an inclusive regional order, based on cosmopolitan values.
