Most jurisdictions have over the past two decades experienced reforms with regard to arbitration law. These include England, America, France, Germany and the Netherlands. These reforms were necessary as the trend in the modern era shows that businessmen situated in different countries usually prefer to have their disputes resolved by arbitration as opposed to court litigation. To have disputes resolved effectively, it is surely a desirable thing to have laws that would promote the use of arbitration as an alternative dispute resolution. This would also ensure progressive international trade which is an important aspect of development in the South African constitutional state. One aspect of the law that would ensure a speedy and effective resolution of dispute by means of arbitration is the incorporation of the doctrine of separability in a country's law. The doctrine of separability provides that an arbitration agreement is a separate and independent contract from the main contract in which it is incorporated. In light of the above, the primary purpose of this study is to compare and analyse the English legal system with that of South Africa with specific focus on the doctrine of separability. / LLM (Import and Export Law), North-West University, Potchefstroom Campus, 2014

The main aim of the study was to determine the prescribing patterns of antibiotics with an emphasis on fluoroquinolones in the private health sector of South Africa. The empirical study followed a quantitative, descriptive, observational method using retrospective, longitudinal medicine claims data provided by a nationally representative Pharmaceutical Benefit Management company (PBM) from 1 January 2005 to 31 December 2012. Penicillins, cephalosporins, carbapenems, aminoglycosides, chloramphenicol, fluoroquinolones, macrolides, tetracyclines, sulphonamides and trimethoprim were considered in the study. A total of 5 155 262 (44.8%) patients received at least one antibiotic prescription out of the total number of registered beneficiaries included in the database. The average number of antibiotic prescriptions per patient per year ranged from 2.22 ± 1.89 (95% CI 2.22-2.22) in 2005 to 1.98 ± 1.62 (95% CI 1.98-1.99) in 2012. The number of antibiotics per prescription per year remained fairly constant at 1.05 ± 0.19 (95% CI 1.05-1.05) in 2005 to 1.06 ± 0.21 (95% CI 1.06-1.06) in 2012. The prevalence of patients receiving antibiotic prescriptions decreased from 46.1% (n = 789 247) in 2005 to 38.2% (n = 480 159) in 2012. Antibiotics were mostly prescribed for females (54.9%, n = 2 831 686) and in patients aged 0 to 18 years (26.5%, n = 1 366 824) and least in patients above 65 years (9.5%, n = 490 496). The prevalence of patients receiving antibiotic prescriptions was highest in Gauteng (41.9%, n = 2 159 360) and lowest in the Northern Cape (1.7%, n = 87 720). Antibiotics were mostly prescribed during the winter period. Penicillins were the most prescribed antibiotics (43%) and carbapenem the least (0.1%) out of the total number of antibiotics claimed. No practically significant association was found between antibiotic prescribing and gender, age, province and season. A total of 1 983 622 prescriptions for fluoroquinolones were claimed in patients older than 18 years. The average number of fluoroquinolone prescriptions per patient per year ranged from 1.45 ± 0.92 (95% CI 1.44-1.45) in 2005 to 1.31 ± 0.71 (95% CI 1.31-1.32) in 2012. The highest prevalence of fluoroquinolone prescribing was observed in females (64.1%, n = 850 253) and in patients between 45 and 65 years (38.6%, n = 511 542). The total fluoroquinolone use by the study population decreased from 2.85 DID in 2005 to 2.41 DID in 2012. Norfloxacin was the only first-generation fluoroquinolone prescribed. The second-generation fluoroquinolones accounted for more than 50% of the total DID, with ciprofloxacin being the most used active ingredient in this generation. Moxifloxacin was the most prescribed third-generation fluoroquinolone; its use ranging from 0.51 DID in 2005 to 0.44 DID in 2012. Between 2005 and 2012, a total of 57 325 prescriptions for fluoroquinolones were claimed by patients 18 years and younger. The prevalence of patients receiving fluoroquinolone prescriptions decreased from 3.6% (n = 8 329) in 2005 to 2.9% (n = 3 310) in 2012. Fluoroquinolones were mostly prescribed to females and in patients between 12 and 18 years. In all age groups, prescribing was mainly done by general medical practitioners. Ciprofloxacin was the most prescribed fluoroquinolone, followed by levofloxacin. In conclusion, this study established estimates on the prevalence of antibiotic prescribing covering an eight-year period. Secondly, baseline estimates for fluoroquinolone prescribing in adults using the ATC/DDD methodology were determined. Fluoroquinolone prescribing patterns in children and adolescents were determined, with specific reference to the comparison between the prescribed daily and recommended daily dosages in the different age groups and by prescribers’ specialties. / MPharm (Pharmacy Practice), North-West University, Potchefstroom Campus, 2015

South Africa‟s current energy sector places undue reliance on fossil fuels to fulfil the country‟s energy requirements. The use of these non-renewable energy resources are unsustainable, as millions of tonnes of harmful emissions are released and estimates are made that these resources will be depleted within the next 100 years. Therefore the country has to source alternative energy resources. Renewable energy resources (for example solar energy) are considered to release little or no harmful by-products and have an infinite supply. Therefore the South African government has to promote the use of renewable energy as part of its commitments to address climate change and to ensure sustainable energy resources. Some of the most popular regulatory tools that a state uses to control human behaviour, is through command-and-control instruments and fiscal instruments. The latter promotes behavioural changes by rewarding desired behaviour which ultimately advances the user‟s own best interest. Because of the nature of renewable energy governance, energy users can not be forced or compelled through commandand- control instruments to use renewable energy. They should rather be encouraged or persuaded to use this form of energy through market-based instruments. This is also the central hypothesis of this dissertation. The purpose of this study is to determine the extent to which the South African legal regime makes provision to promote the use of renewable energy resources through fiscal instruments. Therefore the various energy-related white papers, policy papers and legislation will be analysed. This study found that South Africa‟s legal regime only partly makes provision to promote the use of renewable energy resources through fiscal instruments. The policy part of the legal regime is fairly well developed, but the statutory regime lacks detail and in its current form, environmental/energyrelated legislation does not fully correspond with the lofty objectives of the policy framework. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2015

Rotavirus infection causes severe gastroenteritis, affecting all children under the age of five regardless of hygiene or water quality. The currently licensed vaccines succeeded in reducing diarrhoea worldwide, but they still have shortcomings, especially the efficacy of the vaccines in developing countries. One of the main reasons for this can be due to the difference in strains, since the strains used to develop the currently licensed vaccines (RotaTeq and Rotarix) were selected from strains circulating in the developed world (G1, G2, G3 and G4), while the main strains present in Africa (G8, G9 and G12) were not included. A second shortcoming of the currently licensed vaccines is the cost of these vaccines. The vaccines are very expensive and most developing countries cannot afford the vaccines as well as the fact that the manufacturing companies cannot produce enough vaccines for all the countries. An attractive alternative to the currently licensed rotavirus vaccines is the non-live vaccine candidate, virus-like particles, which can provide a possible cheaper, safer and efficacious alternative or complement the currently licensed vaccines. Therefore, in this study a South African G9P[6] rotavirus strain, RVA/Humanwt/ ZAF/GR10924/1999/G9P[6], was used to determine whether or not co-expression of the structural proteins VP2 (genome segment 2) and VP6 (genome segment 6) was possible in bacteria and yeast. The South African GR10924 G9P[6] neonatal strain was previously obtained from a stool sample and the nucleotide consensus sequence was determined for both genome segment 2 (VP2) and genome segment 6 (VP6). Bacterial codon optimised coding regions or open reading frames were used in this study. The open reading frames (ORFs) of the genome segments encoding, VP2 and VP6, were cloned into the expression vector pETDuet-1, which allows for the simultaneous expression of two genes in bacteria. The ORF of genome segment 6 was purchased from GeneScript and the ORF of genome segment 2 was obtained from Dr AC Potgieter (Deltamune (Pty) Ltd R&D, South Africa). Compatible restriction enzyme sites were used to sub-clone the ORF of the bacterial codon optimised genome segments into the expression vector. Only the expression of the VP6 protein in bacteria was observed with Coomassie stained SDS-PAGE. The ORFs encoding VP2 (genome segment 2) and VP6 (genome segment 6) of the wild type GR10924 G9P[6] strain were cloned into the wide range yeast expression system vector, pKM173, which allows for the simultaneous expression of more than one gene. Several yeast strains were used in this study namely Kluyveromyces marxianus, Kluyveromyces lactis, Candida deformans, Saccharomyces cerevisiae, Yarrowia lipolytica, Arxula adeninivorans, Hansenula polymorpha and Debaryomyces hansenii. Expression of both proteins was not detected in the several yeast strains, as seen with western blot analysis. DNA extractions were done on two colonies of each yeast strain that were used for western blot analysis to evaluate successful integration into the yeast genomes. Only a few of the colonies contained either both of the genome segments or only one of the two genome segments of interest. To summarise, the simultaneous expression of VP2 and VP6 from rotavirus GR10924 G9P[6] was not successful in bacteria or yeast, but it was possible to soluble express the bacterial codon optimised GR10924 G9P[6] VP6 in bacteria using the pETDuet-1 as expression vector. / MSc (Biochemistry), North-West University, Potchefstroom Campus, 2015

Globally an estimated 33.4 million people were living with HIV/AIDS by 2008 (UNAIDS, 2009a:7). One of the main challenges facing the Republic of South Africa (RSA) today is the HIV/AIDS epidemic (NSP, 2007:17). By mid-year 2011 an estimated 5.38 million people (10.6% of the total population) were living with HIV/AIDS in the RSA (Statistics South Africa, 2011:2). Currently South Africa has the largest number of people enrolled in the Highly Active Antiretroviral Treatment programme (HAART) in the world (WHO, 2008:59). The objective of this study was to determine retrospectively the medicine treatment patterns of HAART at a district hospital in the North West Province of South Africa. The study was conducted at Thusong hospital in the Ditsobotla sub-district of the North West Province of South Africa. A non-experimental, retrospective, cross-sectional, drug utilisation research methodology was used to obtain the data. The target population included patients of all ages who visited Thusong hospital pharmacy during the data collection period, which commenced on 01 February 2012 and ended on 31 March 2012. The data of three hundred and ninety nine (N=399) adult and one hundred and sixty one (N=161) paediatric patients on HAART were used. The adult female patients accounted for almost 70% (n=276, 69.17%) and the adult male patients for only 30% (n=123, 30.83%). The male paediatric patients represented just over 60% (n=97, 60.25%), whereas the female paediatric patients comprised less than 40% (n=64, 39.75%). The majority of adult patients were unmarried (n=323, 80.95%) and this group of patients were also the youngest group (μ=36.38 ± 8.98 years) on ARV treatment. Almost 86% (85.96%, n=343) of adult patients were registered as unemployed. Ninety two (n=92, 23.06%) adult patients and fifty eight (n=58, 36.03%) paediatric patients defaulted treatment during the defined period. The investigation into the adult medicine treatment patterns revealed that more than half (52.38%, n=209) of all the adult patients were receiving regimen 1atn (EFV, TDF and 3TC), followed by 20.80% (n=83) on regimen 1a (EFV, D4T and 3TC). Most paediatric patients (n=73, 45.34%) were on regimen P1c (EFV, D4T and 3TC) and the second most (n=45, 27.95%) were on regimen P1a (D4T, 3TC and LPV/r). The average weight of adult female patients was 57.18kg (± 15.78kg) and the average adult male patient weighed 55.87kg (± 10.17kg) on initiation of HAART. The average adult male patient was initiated on HAART with a CD4 count of 130cells/mm3 (± 99.45cells/mm3), while for adult female patients it was 160cells/mm3 (± 96.52cells/mm3). The average male child was initiated with a CD4 count of 509.1cells/mm3 and the average female paediatric patient with 477.3cells/mm3. The average viral load for adult female patients on initiation of HAART was 103046copies/mm3 (± 189146copies/mm3) and for adult male patients it was 416600copies/mm3 (± 439746copies/mm3). The difference between the viral load of adult female and male patients were described as statistically (p=0.0006) and practically (d=0.713) significant. The average viral load for female paediatric patients on initiation of HAART was 242207copies/mm3 (± 709133copies/mm3) and for male paediatric patients it was 329734copies/mm3 (± 674532copies/mm3). Adult patients that received HAART at more than 12 consultations revealed an average weight gain of 3.43kg (± 8.11kg) from initiation of treatment. This group also showed an average increase of 214.71cells/mm3 (± 248.24cells/mm3) in CD4 count and an average reduction in viral load of 170944copies/mm3 (± 191854.69copies/mm3) from the day they started HAART up to the last date of receiving treatment. The paediatric patients on treatment for more than 12 consultations showed an average weight gain of 6.56kg (± 3.75kg) from initiation of ARV treatmentup to the last date of receiving treatment. They also showed an average increase in CD4 count of 396.63cells/mm3 (± 594.53cells/mm3) and a very encouraging average decrease of 538369.37copies/mm3 (± 948634.46copies/mm3) in the viral load. / MPham (Pharmacy Practice), North-West University, Potchefstroom Campus, 2014

Various studies have highlighted the problems faced in accounting education. Some of these problems refer to the stagnating accounting curriculum, limited resources available to students from designated black empowerment groups, and the underdevelopment of skills required by practice. This study focuses specifically on the problems faced in secondary and tertiary accounting education in South Africa (SA) and the effects of these problems on practice. The first article of this study emphasises the various causes for the declining pass rate in firstyear chartered accountancy (CA) students. For this purpose, the researcher gathered information on the perceptions of first-year CA students and of lecturers involved in departments of accounting at SA universities. One of the possible causes identified is the apparent gap between school and university accounting education, especially in respect of curriculum, teaching quality and textbooks. The study revealed that students from designated black empowerment groups are facing the most problems in SA accounting education. The second article addressed the skills shortages in first-year CA trainees that practitioners have to deal with. According to the results, the majority of the participants felt that universities do not sufficiently equip students with the skills necessary to be successful in practice. The skills shortages identified included the inability of first-year trainees to determine the extent of testing needed in audits and to think independently. It also seemed as if first-year trainees lack professional communication skills and cannot sufficiently apply theory learnt at university in practice. These are only some skills with which universities are expected to equip students in order to be successful in practice. The researcher drew conclusions and made recommendations based on the information obtained from the above-mentioned two studies. / MCom (Accountancy), North-West University, Potchefstroom Campus, 2014
