Neuroblastoma: The basis for cure in limited‐resource settings
No full textBackground Neuroblastoma (NB) contributes the most to the mortality of childhood malignancies worldwide. The disease spectrum is heterogenous and the management complex and costly, especially in advanced disease or disease with adverse biology. In low- and middle-income countries (LMICs) the majority of NB presents in advanced stages. Therefore, with limited resources and poor prognosis the treatment of NB is often not a priority. The aim of the study was to evaluate the research activities and perceptions of the management of NB that determine the research and treatment approaches in LMICs. Methods Data were sourced from identifying NB trials open to LMIC. s on NB research presented at the International Society for Paediatric Oncology (SIOP) Congresses between 2014 and 2020 were evaluated according to income status. An online survey evaluating medical views on NB in LMICs and the effect on the management was conducted. Descriptive analysis was done. Where appropriate categorical association between covariates was assessed using the Pearson chi-square (chi(2)) test or Fishers exact test. Results There were 15/562 (2.7%) trials open to LMIC. Only six of 138 (4.3%) LMIC participated in NB trials. Of the 688 abstracts presented between 2014 and 2020 at the SIOP International Congress on NB as primary subject, 297 (42.7%) were from LMICs. Only two were from low-income countries (LICs). Sixty-one countries responded to the NB survey. Positive views towards NB management were present when treatment was based on a national protocol, the availability of trimodal or advanced treatment options were present, and when a balance of metastatic or local disease were treated. Conclusion Management of NB in LMICs should include increased advocacy and research as well as implementation of national management strategies.We appreciate the support offered by Profs Kate Matthey, Guillermo Chantada and Scott Howard on behalf of the Global Neuroblastoma Network, Profs Laila Heississen and Lorna Renner on behalf of SIOPAfrica, Dr Joyce Balagadde-Kambugu on behalf of POGEA in the distribution of the survey.

The historiographic metafiction of Etienne van Heerden
No full textThesis (MA)--Stellenbosch University, 2002.ENGLISH ABSTRACT: This thesis investigates the possibility that there are other ways in which to represent the past, not just the traditional way as practised by historians. For instance, other forms such as historical fiction in the historical novel, and therefore, narrative, can act as an important conduit for conveying historical meaning. Through the examination of the historiographic metafiction of the South African writer, Etienne Van Heerden, this study has concluded that through a reading of both the author's belletristic and theoretical texts, readers interested in history and literature will gain some understanding of the
problems that come with writing up the past. At the same time, they will gain some knowledge of a different way of writing about South African history, because the author portrays the historical events in a refreshing, vivid and imaginative way. However, it needs to be said from the outset that in no way is the writer of this thesis neglecting the merits of traditional history or advocating its abolition, which is, ultimately, the scientific way of representing the past and remains sacred and paramount for the historian, both amateur and professional.AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die moontlikheid dat die verlede volgens ander sienswyses voorgestel kan word en nie slegs volgens die tradisionele sienswyses van historici nie. Daar is byvoorbeeld ander vorme, soos historiese fiksie wat in historiese novelles gebruik word, en daarom kan die narratief as 'n belangrike kanaal dien om historiese betekenis mee oor te dra. Deur 'n ondersoek van die historiese metafiksie van die Suid-Afrikaanse skrywer, Etienne van Heerden, kom hierdie studie tot die gevolgtrekking dat deur die lees van beide die skrywer se belletristiese en teoretiese tekste, lesers wat in die geskiedenis en literatuur belangstel, 'n begrip sal kry van die problematiek wat gepaard gaan met die skryf van geskiedenis. Terselfdertyd sal hulle 'n begrip kry van 'n alternatiewe skryf van die Suid-Afrikaanse geskiedenis, omdat die skrywer historiese gegewens in 'n verfrissende, helder en verbeeldingryke wyse oordra. Dit moet egter beklemtoon word dat die skrywer van hierdie tesis geensins die meriete van tradisionele geskiedskrywing negeer of die afskaffing daarvan voorstaan nie, aangesien die wetenskaplike voorstelling van die verlede kosbaar en van kardinale belang vir beide amateur en professionele historici bly.Master
Contribution of broad-based black economic empowerment to the financial performance of companies listed on the JSE during a recession
No full textDissertation (MBA)--University of Pretoria, 2011.The ANC government has implemented various mechanisms to promote inclusivity of all economic citizens over the past 15 years. The main objectives of all the policies was to promote economic transformation in order to enable meaningful participation of black people in the economy and to change the racial composition of ownership and management structures of existing and new enterprises. The purpose of the research was to determine the contribution of Broad-Based Black Economic Empowerment (BBBEE) to the financial performance of companies on the Johannesburg Stock Exchange (JSE) during the economic recession. The underlying assumption was that companies with greater overall BBBEE compliance rating should outperform companies with a lower overall BEE compliance rating. The top BBBEE rated companies on the JSE were analysed to determine whether these companies outperformed that sector indices. Market-to-book-value, Price-Earnings Ratio and Annual Return were used as financial performance measures. The results showed that there was a positive correlation between the companies’ BBBEE rating and the financial performance. On further investigation it was revealed that on average the companies with greater BBBEE ratings did not outperform companies with lower BBBEE ratings nor did they outperform the sector indices Copyright 2011, University of Pretoria.

<i>In memoriam lingua</i>: ’n linguistiese ondersoek van ’n metafiksionele teks deur Etienne van Heerden
No full textIn memoriam lingua: A linguistic investigation of a metafictional text by Etienne van Heerden
Metafictional texts always problematize explicitly and/or implicitly the ability of language to signify a reality beyond itself It follows that an assessment of a metafictional text should benefit by an investigation of its linguistic fabric. A similar investigation of Etienne van Heerden's short story "Die wederopstanding van Olive” in Liegfahriek (a) outlines a number of the author-narrator's strategies - verbal and non-verbal - in order to circumvent the insignificance of his medium; (b) brings the reader to a realisation of his/her own participation in the stultification of language, and (c) reveals the inherent content of all literary texts
The Book of Jonah and the Hermeneutics of Ferdinand E. Deist: Festschrift for Willie van Heerden
No full textFerdinand E. Deist (1944–1997) was a critical scholar and a prolific author, and had an immeasurable influence on Old Testament and ancient Near Eastern scholarship in South Africa during the last quarter of the previous century. Although he never claimed to be working within the new paradigm which dawned in Old Testament studies towards the end of the nineteenth century, it is evident that he was fully at home within this paradigm. The article does not discuss all Deist’s publications in order to vindicate the claim. It only discusses his earliest publications. His treatment of Jonah opened the doors for many of his students to follow in his wake and to acquaint themselves with historical-critical methods of studying the Bible. Willie van Heerden, who is honoured with this essay, is but one of many postgraduate students who benefitted from Deist’s expertise, courage, and wisdom
Evaluation of alternatives for hydraulic analysis of sanitary sewer systems
No full textThesis (MScEng)--Stellenbosch University, 2014.ENGLISH ABSTRACT: This research project focuses on sanitary sewer systems. When performing an analysis of a sewer drainage system with known constraints, an appropriate model needs to be chosen depending on the objectives of the analysis. Uncertainties are also present in the analysis of sewer drainage systems. The uncertainties and the errors in hydraulic models need to be understood and considered. The required level of accuracy and the type of hydraulic problem that needs to be solved may alter the complexity of the hydraulic model used to solve a drainage system. The wide variety of available simulation models further complicates model selection. With various models available, selecting the most appropriate model for a particular drainage system simulation is important.
The various models for sewer drainage system analysis can be categorised in different ways. For example, it is possible to categorise models according to their purpose, which could be evaluation, design or planning. Evaluation models are mainly used to test whether existing systems or planned systems are adequate and require the highest hydraulic detail. Design models are used to determine the size of conduits within a drainage system and require moderate levels of hydraulic detail. Planning models are primarily used for strategic planning and decision making for urban or regional drainage systems and require the least amount of hydraulic detail. An understanding of the available models is required in order to choose the most suitable simulation model for the desired purpose. Some models are derived from the Saint-Venant equations of flow. The most detailed models are typically referred to as fully dynamic wave models and utilise all the components of the Saint-Venant flow equations. By removing terms from the Saint-Venant equations a kinematic wave model can be created. Some less complex models ignore basic principles of hydraulics in order to make assumptions that simplify the process of simulating flows. In this thesis three different models were compared: a detailed model using fully dynamic flow equations, a simplified model using kinematic wave equations and a basic model using contributor hydrograph routing equations. For the drainage system analysis SWMM-EXTRAN was used as the fully dynamic wave model, SWMM-TRANSPORT was used as the kinematic wave model and SEWSAN was used as the contributor hydrograph model.
Two drainage systems situated in South Africa were used as case studies and are referred to as Drainage System A and Drainage System B in this thesis. The actual flow rate was recorded at two points with flow loggers, one in each of the two systems. The flow rate was continually recorded at 1 hour intervals for the period 1 July 2010 to 9 July 2010 in Drainage System A as well as in Drainage System B. The same input parameters were used for each model allowing the modelled flow rates to be compared to the measured flow rates.
The models provided peak flow results that were within 2% of the measured peak flow rates and the modelled mean flows were within 8.5% of the measured mean flows in most situations. However, when rapidly varied flows occurred the kinematic wave and contributor hydrograph models returned conservative results as they were unable to account for hydraulic effects such as acceleration. The effect of acceleration became most pronounced up and downstream of drop structures and sections where the slope changed considerably. The kinematic wave and contributor hydrograph models were therefore unable to accurately simulate surcharge conditions.
The results suggest that the fully dynamic wave model can be used in all scenarios. The kinematic wave model can be used for a design analysis if no hydraulic structures occur in the system. The contributor hydrograph model should not be used for an evaluation analysis, but can be used for a design analysis if a relatively high level of confidence in the parameter set exists and no areas of rapidly varying flow or hydraulic structures exist within the system.AFRIKAANSE OPSOMMING: Hierdie navorsing projek is gefokus op riool dreineringsisteme. Wanneer ʼn analise van ʼn riool dreineringsisteem met bekende beperkinge onderneem word, moet ʼn geskikte model gekies word afhangende van die doelwitte van die analise. Onbekendes is ook teenwoordig in die analise van riool dreineringsisteme. Dit word belangrik dat die onsekerhede en die foute in hidroliese modelle moet verstaan en oorweeg word. Die verwagte vlak van akkuraatheid en die tipe hidroliese probleem wat opgelos moet word mag die ingewikkeldheid van die hidroliese probleem, wat gebruik word om ʼn rioolsisteem op te los, verander. Die wye verskeidenheid van beskikbare simulasie modelle bemoeilik verder die keuse van ʼn model. Met etlike modelle beskikbaar vir seleksie, is die mees geskikte model vir ʼn spesifieke dreineringsisteem simulasie belangrik.
Die verskeie modelle vir riool dreineringsisteem analise kan op verskillende wyses gekategoriseer word. Byvoorbeeld, dit is moontlik om modelle te kategoriseer volgens hulle doel, wat evaluasie, ontwerp en beplanning kan wees. Evaluasiemodelle word hoofsaaklik gebruik om te toets of huidige of beplande sisteme voldoende is en of hulle die hoogs moontlike hidroliese besonderhede benodig. Ontwerpmodelle word gebruik om die grootte van ʼn leipyp binne ʼn rioolsisteem te bepaal en benodig matige vlakke van hidroliese besonderhede. Beplanningsmodelle word hoofsaaklik gebruik vir strategiese beplanning en besluitneming vir stedelike en landelike rioolsisteme en benodig die laagste vlak van hidroliese data. ʼn Begrip van die beskikbare modelle is nodig om ʼn keuse te maak rakende die mees geskikte simulasie model vir die verlangde doelwit. Sommige modelle is afkomstig van die Saint-Venant vergelykings van vloei. Die mees gedetailleerde modelle word tipies na verwys as die volledige dinamiese golf modelle en benut alle komponente van die Saint-Venant vloei vergelykings. Deur die verwydering van terme van die Saint-Venant vergelykings kan ʼn kinematiese golf model daargestel word. Sommige minder gekompliseerde modelle ignoreer die basiese beginsels van hidrologie om aannames te maak wat die proses van golf simulering vereenvoudig. In hierdie tesis is drie verskillende modelle vergelyk; ʼn gedetailleerde model wat volledige dinamiese vloeivergelykings gebruik; ʼn vereenvoudigde model wat kinematiese golfvergelykings gebruik en ʼn basiese model wat bydraende hidroliese versending vergelykings. Vir die dreineringsisteem analise was SWMM-EXTRAN gebruik as die volledige dinamiese golfmodel, SWMM-TRANSPORT was gebruik as die kinetiese golfmodel en SEWSAN was gebruik as die bydraende hidroliese model.
Twee dreineringsisteme in Suid-Afrika was gebruik as gevallestudies en word na verwys as Dreineringsisteem A en Dreineringsisteem B. Die werklike vloeikoers was aangeteken by twee punte met vloeimeters, een in elk van die sisteme. Die vloeikoers was deurlopend opgeteken met 1 uur tussenposes vir die periode 1 Julie 2010 tot 9 Julie 2010 in Dreinering Sisteem A sowel as Dreinering Sisteem B. Dieselfde inset parameters was gebruik vir elke model wat dit moontlik gemaak het dat die gemoduleerde vloeikoerse met die gemete vloeikoerse vergelyk kon word.
Die modelle het spits vloeiresultate voorsien wat binne 2% van die gemete spits vloeikoerse was en, in die meeste situasies, dat die gemoduleerde gemiddelde vloei binne 8.5% van die gemete gemiddelde vloei was. Wanneer vinnig varierende vloei voorgekom het, die kinetiese golf and bydraende hidrograaf modelle konserwatiewe resultate gelewer het, aangesien hulle nie in staat was om hidroliese effekte soos versnelling te verklaar nie. Die effek van versnelling was op sy duidelikste stroomopwaarts en stroomafwaarts onder valstrukture en by gedeeltes waar die helling aansienlik verander het. Die kinetiese golf en bydraer hidrograaf modelle was gevolglik nie in staat om oorladingsomstandighede akkuraat te simuleer nie. Die resultate wys dat die volledige dinamiese vloeimiddel gebruik kan word in alle omstandighede. Die kinematiese vloeimiddel kan gebruik word vir ʼn ontwerp analise indien geen hidroliese struktuur in die sisteem voorkom nie. Die bydraer hidrograaf model behoort nie gebruik te word vir ʼn evaluerings analise nie, maar kan gebruik word vir ʼn ontwerp analise indien ʼn relatiewe hoë vlak van vertroue in die parameter stel bestaan en geen area van vinnig veranderende vloei of hidroliese strukture binne die sisteem bestaan nie
Avian impact of South Africas first concentrating solar power tower facility in the Northern Cape
No full textThesis (MScConsEcol)--Stellenbosch University, 2020.ENGLISH ABSTRACT: Through its commitment to a greener economy that is less dependent on nonrenewable energy resources, South Africa’s Integrated Resource Plan aims to diversify the energy system by including energy resource alternatives such as concentrating solar power (CSP). All CSP facilities harvest solar thermal energy by utilising reflectors that focus energy to a receiver where the energy is concentrated and eventually converted into electricity via a conventional thermoelectric power cycle. Four main types of CSP technologies exist in today’s global market of which central receivers, also known as CSP towers, are one of the dominant types. Recent studies suggest that the potential impacts of utility-scale CSP tower facilities on avian populations may be substantial given that these impacts are driven by factors such as project location, footprint size and technology. It is anticipated that these factors mainly impact avifauna by altering the demography of avian communities and by exposing birds to singeing and collision risk. However, given the novelty of tower CSP and the global shortfall of publicised data on avian impacts, conclusive investigations into the avian impact of these facilities have yet to be established. Further rigorous investigation of these factors is therefore encouraged. This study was the first to investigate the impact of a solar power tower facility in South Africa, seeing that it was conducted on the only operational CSP tower facility in southern Africa. The study aimed to evaluate the impact of the Khi Solar One CSP tower facility on avifauna of the area with special attention to biodiversity dynamics and avian mortalities and injuries. Industry best practice guidelines and peer-reviewed literature were used as the point of departure from which the fieldwork methodology was developed. Data on avian mortality and injury were gathered over four seasons by conducting weekly monitoring and identifying patterns of avian use by means of vantage point surveys and parallel-line transects that were conducted inside and outside the facility footprint. Data collected during the field surveys were analysed to determine a suitable risk analysis model for this kind of development and to determine whether and to what extent the development had caused a change in avian behaviour.
The findings demonstrate that concerns about the impacts of CSP towers on bird populations are not completely unsubstantiated, even though some results remain inconclusive. Avian species diversity, abundance and density per unit area were found to be higher in the neighbouring untransformed habitat than within the facility footprint. Data suggest that certain shrubland/woodland species favoured the CSP facility, however, they did not represent an unaffected population by default. In contrast, generalist and open country/grassland species were not adversely affected by impacts caused by the CSP tower facility. The presence of constructed water bodies and structures within the transformed habitat also appeared to have an indirect impact as in this otherwise rural habitat, they lure a diversity of aquatic and other species that favour a more urban habitat. Breeding observations indicated that reproductive activity within the transformed habitat was lower than within the untransformed habitat.
A total of 324 avian impact detections were recorded during the monitoring year, involving 34 identified species. Of the total avian impact detections, 61% of injuries/mortalities were found to be caused impact trauma and 14% by singeing related trauma. Most collisions were recorded in the solar field with trending evidence of impact occurring on the lower quarter of the heliostats’ reflective surfaces. Singeing data displayed a significant increase in detections during the summer months and revealed that most recorded detections were of aerial feeding migratory birds. A clear correlation was found between the peak singeing detection months and the positioning of heliostats into the standby position during this period. It was difficult to make a meaningful assessment of the overall avian fatality at CSP tower facilities and to formulate accurate hypotheses regarding the risk of avian mortality among these facilities and other sources of solar electricity generation. Still, data suggested that fatalities per area may be a more suitable metric for estimating cumulative impacts among CSP tower facilities since the efficiency of this technology is continuing to improve and change in design and operation over time. Ultimately, this study offers several findings and recommendations that may contribute to the compilation of a mitigation framework that will ensure that the industry develops in a sustainable manner in South Africa.AFRIKAANSE OPSOMMING: In die strewe na 'n omgewingsvriendelike (groener) ekonomie, is dit van kritiese belang, vir Suid-Afrika, om minder afhanklik te wees van fossielbrandstowwe of, anders genoem, nie-hernubare energiebronne. Suid-Afrika se Geïntegreerde Hulpbronplan maak dit dan ook moontlik vir rolspelers, op hierdie gebied, om betrokke te raak in die voorsienning van hernubare energie vir die land. Sonverwarmingstelsels of te wel “concentrating solar power” (CSP) is een voorbeeld van so 'n alternatiewe wyse van kragopwekking.
‘n CSP-aanleg produseer termiese sonkrag deur gebruik te maak van spieëls wat die sonstrale gefokus weerkaats na 'n ontvanger, waar die energie gekonsentreer word. Hier word die termiese energie dan omgesit in elektriese energie deur 'n konvensionele termo-elektriese energiesirkel. Daar is vier basiese wyses (tegnologieë) waardeur bogenoemde bereik kan word, met CSP-torings as een van die mees prominente.
Daar moet egter ook, wat hernubare- energieopwekking, betref, deurgaaans bepaal word wat die invloed van hierdie tipe ontwikkeling op die omgewing is. So toon verskeie studies byvoorbeeld aan, dat voëls tipiese slagoffers van die tipe ontwikkelings is, met die ligging, omvang asook die tipe aanleg (tegnologie) wat bepalend is tot in 'n hoe groot mate die impak is. Aanlegte kan 'n invloed uitoefen deur habitatversteuring, verskroeiing en dan ook deur fisiese botsings met hierdie nuwe, vreemde objekte in die voëls se natuurlike hou areas. Siende dat CSP-torings onlangse ontwikkelings is, is daar plaaslik sowel as internasionaal, beperkte inligting wat spesifiek, oor hierdie potensiële impak op voëlbevolkings, handel. Dit het dus dringend noodsaaklik geword om hierdie veld in diepte te ondersoek.
Hierdie navorsing is die eerste van hierdie aard in Suid-Afrika en is onderneem op die enigste operasionele CSP-toringaanleg in suidelike Afrika. Die navorsing is gedoen om te bepaal wat die impak, van die Khi Solar One CSP Tower op die verskillende voëlbevolkings in die gebied het, werklik is. Spesifieke aandag is geskenk aan die invloed op biodiversiteit, verskroeiing (solar flux) en botsings tussen voëls en objekte in die CSP aanleg.
Riglyne daar gestel deur die industrie, sowel as reeds toepaslik nagevorste inligting in die verband, is as vertrekpunt gebruik in die ontwikkeling van 'n model vir die veldwerk. Die versameling van data, van geaffekteerde voëls, het oor vier seisoene geskied. Weeklikse monitering en identifisering is gedoen op die terrein van die aanleg self, sowel as op die aangrensende areas. Hierdie aksie het op 'n bepaalde wyse geskied en is daar seker gemaak dat die gebied deeglik gefynkam word deur vanuit verskillende hoeke, met oorkruisaksies die gebied te deursoek. Data is bestudeer om gebruik te kan word om 'n risiko-analisemodel, vir hierdie tipe ontwikkeling, daar te stel. Hieruit kon bepaal word watter invloed en in hoe 'n groot mate, die voëls se gedrag, indien enigsins, verander of beïnvloed is.
Die resultate toon wel aan dat CSP-torings 'n invloed op die verskillende voëlbevolkings het, maar kan dit nie sonder meer as ingrypend beskou word nie. Baie interessant, wel, is die waarneming wat gemaak is dat die spesie-diversiteit, -getalle en -digtheid, van die verskillende voëlbevolkings, hoër is in die aangrensende gebiede as op die aanleg self. Tog is daar ook bewyse dat sommige spesies, veral die wat normaalweg in bos- en woudagtige habitatte voorkom, in 'n redelike mate na die CSP-toringarea gelok word. Hierdie spesies verteenwoordig egter nie 'n ongeaffekteerde groep nie, en word, in 'n beduidend kleiner mate, deur die aanleg benadeel. Verdampingsdamme en ander bronne van water, binne die aanleg, het ook 'n indirekte invloed op veral akwatiese-voëls, deurdat hulle na die bronne aangetrek word. Ook spesies wat daarvoor bekend is dat hul in beboude gebiede aangepas het, is ook geredelik deur die aanleg gelok. Tog ook hier, herhaal die tendens, dat die voëls steeds die gebiede, aangrensend tot die aanleg, as broeiplek, verkies het. Gedurende die tydperk van monitering (12 maande) is 324, beseerde of noodlottig beseerde voëls gevind, verteenwoordigend van 34 spesies. Daar kon bepaal word dat 61% van die beseerde of noodlottig beseerde voëls, in botsing was met strukture op die aanleg, terwyl 14% deur skroeiing beseer of gedood is. Verder is vasgestel dat die meerderheid van die botsings van die voëls met strukture, plaasgevind het in die heliostat-gebied, met die meerderheid botsings in die onderste kwart van die heliostats. Data vir voëls deur skroeiing gedood of beseer, toon dat dit veral migrende, lugjagters (aerial feeders) is wat hier ten prooi val, veral gedurende die somermaande. Wanneer die heliostats in die bystandposisie geposisioneer is, is die ongevalle dienooreenkomstig kleiner.
Dit is moeilik om 'n sinvolle assessering in die algemeen, wat beserings en sterftes van voëls, spesifiek vir CSP-toringaanlegte, asook ander vorme van opwekking, te maak en om te bepaal wat die werklike risiko vir voëlspesies is. Nogtans het data getoon dat sterftes per ‘n spesifieke gestandardiseerde area 'n meer geskikte wyse kan wees vir die beraming van die kumulatiewe impak onder CSP-toringfasiliteite.
Hierdie studie bied verskeie bevindings en aanbevelings wat kan bydra tot die daarstel van 'n versagtingsraamwerk. Dit sal verseker dat die bedryf op 'n sensitiewe en volhoubare wyse verder in Suid-Afrika ontwikkel.Master
Twee benaderings tot "twin peaks" : 'n vergelykende beoordeling van die modelle van finansiele regulering in Nederland en Suid-Afrika
No full textThis contribution is based on research conducted by the second author for her doctoral thesis titled "The role of the central bank in promoting and maintaining financial stability in South Africa" (LLD thesis UP 2018), completed under supervision of the first author with input from the third author.'n Land se model van finansi8le regulering is bepalend tot die vermoe om finansiele stabiliteit in 'n bepaalde finansiele stelsel te bevorder en in stand te hou. Die "Twin Peaks"-model van finansiele regulering, wat in 1995 deur Michael Taylor gekonseptualiseer is, word wyd beskou as 'n optimale institusionele struktuur, waar sistemiese en prudensiele regulering en toesighouding in een regulatoriese piek gelokaliseer is, terwyl die ander regulatoriese piek verantwoordelik is vir regulering en toesighouding van finansiele instellings se besigheidsgedrag. Elke piek het 'n sisteemwye mandaat wat in beginsel alle finansiele instellings in 'n gegewe finansiele stelsel dek. Die Twin Peaksmodel is in 1998 in Australi8 ingelei en het sedertdien in gewildheid toegeneem. Nederland was die eerste Europese lidland om hierdie model aan te neem (in 2002) en in werking te stel (in 2007). Suid-Afrika het in 2017 die eerste ontwikkelende land geword wat van 'n sektorale model van finansiele regulering na 'n Twin Peaks-model oorgeskakel het. Hierdie bydrae stel na die Twin Peaks-modelle in Nederland en in Suid-Afrika ondersoek in. Dit bied 'n oorsig oor die onderskeidende kenmerke van elke model en die basiese institusionele opsigte waarin die modelle verskil. Kritiese aspekte van regulatoriese modelle met betrekking tot die vraag of die sentrale bank se mandaat sisteemwye finansiele stabiliteit, sowel as prudensiele regulering en oorsig moet insluit, word bespreek, asook die noodsaaklikheid van 'n omvattende netwerk vir samewerking en uitruiling van inligting. Nederland se ervaring met hul Twin Peaks-model tydens die 2008 Wereldwye Finansiele Krisis bied 'n besonder insiggewende gevallestudie en hierdie bydrae wys verskeie lesse wat Suid-Afrika by Nederland, as voorloper met die invoering van die Twin Peaks model in Europa pas voor die krisis, kan leer uit.http://www.lexisnexis.co.zaam2021Mercantile La
