Text in Afrikaans / Die verweer van nie-patologiese ontoerekeningsvatbaarheid in die Suid-Afrikaanse strafreg word bespreek. Hierdie verweer is van onlangse oorsprong en verskil van die verwere van ontoerekeningsvatbaarheid as gevolg van jeugdigheid en geestesongesteldheid soos in artikel 78(1) van die Strafproseswet 51 van 1977 uiteengesit word. Die verweer van nie-patologiese ontoerekeningsvatbaarheid dek gevalle waar dit deur faktore soos emosionele spanning veroorsaak is. Hierdie verweer staan ook as die algemene ontoerekeningsvatbaarheidsverweer bekend. In 'n aantal beslissings, soos onder andere, S v Arnold 1985 (3) SA 256 (C); S v Campher 1987 (1) SA 940 (A) en S v Chretien 1981 (1) SA 1097 (A), word die gevolgtrekking gemaak dat die verweer van nie-patologiese ontoerekeningsvatbaarheid wei in die Suid-Afrikaanse strafreg bestaansreg het. Ten einde met 'n verweer van nie-patologiese ontoerekeningsvatbaarheid te slaag, is die blote ipse dixit van die beskuldigde onvoldoende. 'n Behoorlike grondslag vir die verweer moet gele word. Die bewyslas in die geval van 'n verweer van nie-patologiese ontoerekeningsvatbaarheid word bespreek. / The defence of non-pathological criminal incapacity in the South African criminal law is discussed. It is a relatively new defence and should be distinguished from the defences such as youth and mental illness set out in section 78(1) of the Criminal Procedure Act 51 of 1977. This defence covers cases in which criminal capacity is excluded by factors such as intoxication and emotional stress. It is also known as a general defence of criminal incapacity. In a number of cases, inter alia in S v Arnold 1985(3) SA 256 (C); S v Campher 1987 (1) SA 940 (A) and S v Chretien 1981 (1) SA 1 097 (A) the conclusion is reached that the defence, non-pathological criminal incapacity, does have a right of existence in the South African criminal law. In order to successfully raise the defence on non-pathological criminal incapacity, the mere ipse dixit of the accused is insufficient. A proper foundation for the defence must be laid. The onus of proof is discussed. / Criminal & Procedural Law / LL. M.

The issue of the vertical /or horizontal operation of the Bill of Rights (chapter 3) is a controversial one. The interim constitution deals with this controversy in a subtle way by avoiding direct horizontal operation of Chapter 3. Instead, it provides for the so-called 'seepage to horizontal relationships' in terms of section35{3). This apparently was a political compromise between the pro-vertical only and the pro-horizontal groups. The human rights history of this country justifies a Bill of Rights that would have both vertical and horizontal operation. However, in section 35 (3) there is potential for the values enshrined in the constitution and Chapter 3, and the spirit hereof, to permeate and filter through the entire legal system in all it's applications. It would seem, however, as demonstrated by the decision in De Klerk v Du Plessis, that the extent to which this filtering process will benefit individuals in their private relations, will depend on the interpretation given to section 35 (3) by the courts. If courts, as it happend in De Klerk's case fail to realise the full import of section 35 ( 3) aspects of the existing law which are unjust could remain and the process of creating a just, open and democratic society will be hampered. / Constitutional, International & Indigenous Law / LL.M.

En jämförelse av Abetongs beräkningsunderlag och statistik från tryckprov visar att sliprarna klarar mycket mer belastning än vad beräkningarna visar. I den här studien har en utvärdering av använda beräkningsmetoder gjorts, samt en jämförelse mellan olika dimensioneringsprinciper för att komma så nära resultaten vid tryckprov som möjligt. Beräkningar med förenklat tryckblock och idealiserad-rektangulär parabolisk arbetskurva visade att det senare alternativet gav ett något högre värde på sliprarnas momentkapacitet, men förändringen förklarade inte varför den verkliga momentkapaciteten är så mycket högre än den framräknade. Den faktor som enligt den här undersökningen påverkar betongens tryckhållfasthet och i sin tur ger en större momentkapacitet än vad tidigare beräkningar visar är förhindrad tvärutvidgning. Studien visar att hänsyn till förhindrad tvärutvidgning bör tas med i beräkningar på betongsliprars hållfasthet. Detta medför att det finns utrymme att minska betongklass på Abetongs slipermodell A26 från C58/70 till C50/60. / A comparison of the calculation data from Abetong and statistics from pressure tests shows that the sleepers can handle more load than the calculations show. In this study, an evaluation of used calculation methods has been made and a comparison between different principles of dimensioning to get as close to the result from the pressure tests as possible. Calculations with rectangular stress distribution and idealized parabola-rectangle diagram showed that the second alternative gave a bit higher value on the sleeper bending moment capacity, but the difference did not explain why the real bending moment capacity is so much higher than the calculated one. According to this study confined concrete gave a larger capacity than the previous calculations. With regards to that effect the compressive strength of the concrete almost doubled, which together with an increased critical strain gave a bending moment capacity very close the one obtained from the pressure tests. This study concludes that the confined concrete effect should be considered when calculating the concrete strength. This also means that there is a possibility to reduce the concrete strength of Abetong’s sleeper model A26 from C58/70 to C50/60.

Thesis (MAcc)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Section 24C of the Income Tax Act No. 58 of 1962 (‘the Act’) provides for a deduction of future expenditure that will be incurred by the taxpayer in the performance of his obligations under a contract from which the taxpayer derived income. Due to uncertainties regarding the meaning of certain words and phrases used in section 24C, the first aim of this assignment was to determine the meaning of the word ‘expenditure’ and the phrase ‘will be incurred’ as used in section 24C. The second aim was to establish how a taxpayer will prove with certainty that he will incur future expenditure in the performance of his obligations under a contract. This was done by discussing the effect of contractual terms and other circumstances and by taking into account certain additional guidelines regarding the interpretation of section 24C provided for in Interpretation Note: No. 78 (‘IN 78’). It was established that the word ‘expenditure’ means the amount of money spent, including the disbursement of other assets with a monetary value. The word ‘expenditure’ also specifically includes the voluntary payments and disbursements of assets. The word ‘expenditure’ can also include a loss if the word ‘loss’ can be equated to the word ‘expenditure’. The phrase ‘will be incurred’ implies that the taxpayer will, in a subsequent year of assessment, have an unconditional obligation to pay for expenditure, which must arise from the taxpayer’s obligations to perform under the contract. Contractual terms and other circumstances can indicate whether there is certainty that future expenditure will be incurred as aforementioned. Conditions and warranties are contractual terms that indicate that there is uncertainty regarding the taxpayer’s obligations to perform under the contract. A time clause in a contract can indicate that there is certainty regarding the taxpayer’s obligations to perform under the contract. Similar contracts with similar conditional obligations to perform cannot be grouped together in order to determine the probability, and thus the certainty, that future expenditure will be incurred in the performance of the taxpayer’s obligations under a contract. The probability that a taxpayer will perform his unconditional obligation under the contract must, however, be proved in order to demonstrate that there is certainty regarding the incurral of the future expenditure. IN 78 does not specify whether a loss which can, in certain circumstances, be equated to the word ‘expenditure’, is deductible under section 24C. This should be clarified. The new undefined phrases (a high degree of probability, inevitability, certainty and potentially contractually obligatory), as used in IN 78, might cause confusion when interpreting section 24C. These phrases should be defined and it should be explained how the high degree will be measured. Lastly, is was shown that an anomaly occurs regarding trading stock at hand at the end of a year of assessment, which will be utilised in a subsequent year of assessment in the performance of the taxpayer’s obligations under a contract. Such trading stock does not represent ‘future expenditure’ and must be excluded from the section 24C allowance. However, due to the interplay between section 24C and section 22(1), the taxpayer does not receive any tax relief for the expenditure actually incurred to acquire the closing trading stock in the year in which such trading stock is acquired. It is, therefore, questioned whether the established interpretation of section 24C is in agreement with the Legislator’s original intention with section 24C namely, to match income received under a contract with the related deductible expenditure. / AFRIKAANSE OPSOMMING: Artikel 24C van die Inkomstebelastingwet No. 58 van 1962 (‘die Wet’) voorsien ʼn aftrekking vir toekomstige onkoste wat deur die belastingpligtige aangegaan sal word in die nakoming van sy verpligtinge ingevolge ʼn kontrak waaruit hy inkomste verkry het. As gevolg van onsekerhede ten opsigte van die betekenis van sekere woorde en frases wat in artikel 24C gebruik word, was die eerste doelstelling van hierdie navorsingswerkstuk om die betekenis van die woord ‘onkoste’ en die frase ‘aangegaan sal word’, soos wat dit in artikel 24C gebruik word, te bepaal. Die tweede doelstelling was om vas te stel hoe 'n belastingpligtige met sekerheid sal bewys dat hy toekomstige onkoste sal aangaan in die nakoming van sy verpligtinge ingevolge ʼn kontrak. Dit is gedoen deur die effek van kontraksbedinge en ander omstandighede te bespreek en deur sekere bykomende riglyne ten opsigte van die interpretasie van artikel 24C, soos vervat in Interpretasienota No. 78 (‘IN 78’), in ag te neem. Daar is vasgestel dat die woord ‘onkoste’ die bedrag van geld wat bestee word, insluitend die uitbetaling van ander bates met 'n geldwaarde, beteken. Die woord ‘onkoste’ sluit ook spesifiek vrywillige betalings en uitbetalings van bates in. Die woord ‘onkoste’ kan ook 'n verlies insluit, indien die woord ‘verlies’ gelyk gestel kan word aan die woord ‘onkoste’. Die frase ‘aangegaan sal word’ impliseer dat die belastingpligtige, in 'n daaropvolgende jaar van aanslag, 'n onvoorwaardelike verpligting sal hê om vir onkostes te betaal. Hierdie onkostes moet ontstaan weens die belastingpligtige se verpligtinge ingevolge die kontrak. Kontraksbedinge en ander omstandighede kan aandui of daar sekerheid is dat die toekomstige onkoste, soos hierbo genoem, aangegaan sal word. Voorwaardes en waarborge is kontraksbedinge wat daarop dui dat daar onsekerheid is rakende die belastingpligtige se verpligtinge om ingevolge die kontrak op te tree. ʼn Tydsklousule in 'n kontrak kan aandui dat daar sekerheid is rakende die belastingpligtige se nakoming van sy verpligtinge ingevolge die kontrak. Soortgelyke kontrakte, met soortgelyke voorwaardelike verpligtinge kan nie saam gegroepeer word ten einde te bepaal of dit waarskynlik, en gevolglik seker is dat toekomstige onkoste in die nakoming van ʼn belastingpligtige se verpligtinge ingevolge die kontrak aangaan sal word nie. Die waarskynlikheid dat 'n belastingpligtige sy onvoorwaardelike verpligting ingevolge die kontrak sal nakom moet egter bewys word ten einde aan te dui dat daar sekerheid is dat toekomstige onkoste aangegaan sal word. IN 78 spesifiseer nie of 'n verlies wat, in sekere omstandighede, gelyk gestel kan word aan die woord ‘onkoste’, ingevolge artikel 24C aftrekbaar is nie. Duidelikheid hieromtrent moet verskaf word. Die nuwe, ongedefinieerde frases ('n hoë graad van waarskynlikheid, onafwendbaarheid, sekerheid en potensieel kontraktueel verpligtend (vry vertaal)), soos in IN 78 gebruik, kan moontlik verwarring veroorsaak wanneer artikel 24C geïnterpreteer word. Hierdie frases moet gedefinieer word en daar moet verduidelik word hoe ʼn hoë graad gemeet gaan word. Laastens blyk dit dat 'n teenstrydigheid ontstaan ten opsigte van handelsvoorraad op hande aan die einde van 'n jaar van aanslag, wat in 'n daaropvolgende jaar van aanslag deur die belastingpligtige in die nakoming van sy verpligtinge ingevolge 'n kontrak gebruik sal word. Sodanige handelsvoorraad verteenwoordig nie ‘toekomstige onkoste’ nie en moet by die artikel 24C toelaag uitgesluit word. Die belastingpligte ontvang egter, weens die wisselwerking tussen artikel 24C en artikel 22(1), nie ʼn belastingverligting vir die onkoste werklik aangegaan in die jaar waarin sodanige handelsvoorraad verkry is nie. Dit word dus bevraagteken of die bewese interpretasie van artikel 24C in ooreenstemming is met die Wetgewer se oorspronklike bedoeling met artikel 24C, naamlik, om inkomste ontvang ingevolge ʼn kontrak met die verwante aftrekbare uitgawes te paar.

Thesis (MDF (Development Finance))--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: It is a fact that development aid represents the single most important source of external finance for most developing countries. This study sought to answer an important question relating to whether aid has a positive impact on economic growth or not. There is much literature on the subject and the views are quite diverse. Using the World Development Indicators (WDI) data, a cross-section regression analysis was performed over a period of 16 years and existing literature on the subject was re-examined. Of importance, this study tries to understand what the determinants or triggers of economic growth are, especially in developing economies. The results show that, although no significant relationship could be found between economic growth and development aid, there is strong evidence that there is a significant positive relationship between economic growth and the important triggers of economic growth used in the study, namely exports and investments. These are important components for the growth of any economy. The implicit conclusion is that since these two components are being impacted positively by aid, it follows then that the link between economic growth and aid can be considered to be a positive one. These findings go against the critics of development aid who maintain that aid that is being pumped into developing economies, especially the African continent, is actually just going into a big black hole and could be used more effectively somewhere else. This study proves that this is not the case and donor countries need to intensify their efforts of providing aid to poor countries because they need it and it is actually making a difference. AFRIKAANSE OPSOMMING: Dit is ‘n algemeen aanvaarde feit dat ontwikkelingsteun die enkel belangrikste bron van eksterne finansiering is vir die meeste ontwikkelende lande. Hierdie studie poog om antwoorde te vind vir die belangrike vraag of steun ‘n positiewe impak op ekonomiese groei het of nie. Daar is volop literatuur oor die onderwerp beskikbaar en die opvattings is uiters uiteenlopend. Deur die World Development Indicators data te gebruik, is ‘n deursnit regressie analise gedoen oor ‘n periode van 16 jaar en bestaande literatuur oor die onderwerp is weer ondersoek. Die belangrikste oogmerk van die studie is om te probeer verstaan wat die bepalers of snellers van ekonomiese groei is, veral in ontwikkelende ekonomië. Die uitslae toon dat, alhoewel daar geen beduidende verhouding gevind kon word tussen ekonomiese groei en ontwikkelingsteun nie, daar wel sterk bewyse is vir ‘n beduidende positiewe verhouding tussen ekonomiese groei en die belangrike snellers van ekonomiese groei soos gebruik in die studie, naamlik uitvoere en beleggings. Hierdie is belangrike komponente vir die groei van enige ekonomie. Die implisiete afleiding is dus dat, aangesien hierdie twee komponente positief beïnvloed word deur ontwikkelingsteun, dit volg dat die skakel tussen ekonomiese groei en steun ook as ‘n positiewe een beskou kan word. Hierdie bevindings is lynreg in teenstelling met die kritici van ontwikkelingsteun wat handhaaf dat steun wat aan ontwikkelende lande, veral in Afrika, gegee word, eintlik net in ‘n groot swart gat verdwyn en meer effektief elders aangewend kan word. Hierdie studie bewys dat dit nie die geval is nie en dat skenker lande eerder hulle pogings om steun aan arm lande te bied moet verskerp omdat hulle dit nodig het en omdat dit regtig ‘n verskil maak.

Three clinical investigations together with a combined editorial and review of the cardiovascular physiology of spinal anaesthesia in normal and preeclamptic pregnancy form the basis of a thesis to be submitted for the degree of Doctor of Medicine at the University of St Andrews. First, the longstanding consensus that spinal anaesthesia could cause severe hypotension in severe preeclampsia was examined using three approaches. The doses of ephedrine required to maintain systolic blood pressure above predetermined limits were first compared in spinal versus epidural anaesthesia. The doses of ephedrine required were then similarly studied during spinal anaesthesia in preeclamptic versus normal control subjects. The principal outcome of these studies, that preeclamptic patients were resistant to hypotension after a spinal anaesthetic, was then further investigated by studying pulse transit time (PTT) changes in normal versus preeclamptic pregnancy. PTT was explored both as beat-to-beat monitor of cardiovascular function and also as an indicator of changes in arterial stiffness. The cardiovascular physiology of obstetric spinal anaesthesia was then reviewed in the light of the three clinical investigations, developments in reproductive vascular biology and the regulation of venous capacitance. It is argued that the theory of a role for vena caval compression as the single cause of spinal anaesthetic induced hypotension in obstetrics should be revised.

The rapid neutron-capture process, known as the r-process, is responsible for the origin of about half the stable nuclei heavier than iron observed in nature. Though the r-process is believed to take place in explosive stellar environments and to involve a large number (few thousands) of exotic nuclei, this nucleosynthesis process remains poorly understood from the astrophysics as well as nuclear physics points of view. On the nuclear physics side, the nuclei are too exotic to be studied in the laboratory, even though great efforts are constantly made to extend the experimental limits away from the eta-$stability region. Therefore, theoretical models are indispensable to estimate the nuclear properties of interest in the r-process nucleosynthesis modelling. So far, models used to predict the properties of the exotic nuclei were based on parametrized macroscopic-type approaches the reliability of which is questionable when extrapolating far away from the experimentally known region. This work is devoted to the improvement of nuclear predictions, such as the nuclear ground- and excited-state properties, needed as input data to model the r-process. In order to give the predictions a reliable character, we rely on the microscopic mean-field Hartree-Fock theory based on the Skyrme-type interaction. Pairing correlations play an important role in the description of nuclei, and become essential for nuclei located near the drip lines, since the scattering of pairs of quasi-particles into the continuum increases significantly. In this work, we brought to the Hartree-Fock model the self-consistent treatment of the pairing correlations within the Hartree-Fock-Bogoliubov (HFB) theory. Further improvements are made in the restoration of symmetries broken by correlations added in the form of additional degrees of freedom in the wave function. These include the translational invariance restored by calculating the recoil energy, the particle-number symmetry by an exact projection after variation, the rotational symmetry by an approximate cranking correction and the parity symmetry for reflection asymmetric shapes. In addition, the renormalization of the HFB equations has been studied as well and allows to eliminate the dependence of the total energy with respect to the cutoff energy. The effective nucleon-nucleon interaction is determined by adjusting its parameters on all available experimental masses, with some constraints derived from fundamental nuclear matter properties. A systematic study of the influence on mass predictions for each of the above cited improvements as well as of some uncertainties affecting the particle-hole and particle-particle interactions has been conducted. In spite of quite important differences in the input physics, we find a great stability in the mass predictions for exotic neutron-rich nuclei, though local mass differences can be significant. Each of the Skyrme force derived in the present work has been tested on the predictions of basic ground-state properties (including charge radii, quadrupole moments, single-particle levels), fission barriers and electric dipole $gamma-$ray strengths. The HFB predictions globally reproduce experimental data with a level of accuracy comparable with the widely-used droplet-like models. The microscopic character of the approach followed in the present work makes however the predictions for exotic neutron-rich nuclei involved in the r-process more reliable. The influence of such improved nuclear mass predictions on the r-process abundance distribution is studied in the specific scenario of the prompt supernova explosion mechanism.

Au cours des dernières décennies, l’augmentation du nombre de guerres irrégulières place les armées modernes dans une situation délicate. Pour pouvoir relever ce nouveau défi, ces organisations militaires, avant tout destinées à mener des guerres interétatiques, se doivent d’innover. Plusieurs cas historiques montrent comment, face à de nouvelles formes de conflit, certaines armées se sont lancées dans un processus d’innovation. Le cas de l’armée française en Algérie en est un. L’objectif de ce mémoire est de comprendre comment l’innovation a émergé lors du conflit, et comment elle s’est diffusée au sein de l’organisation militaire. Un survol de la stratégie française en Algérie va permettre de dégager trois principales innovations : La mise en place de la doctrine de la guerre révolutionnaire, la création des Sections Administratives Spécialisées et l’approche de David Galula. L’étude de ses trois cas nous montre que, durant la Guerre d’Algérie, l’innovation provenait principalement des militaires, plus précisément du sommet de la hiérarchie. Cependant, certains exemples d’innovation par le bas existent. Dans ces cas-là, la diffusion se fera via la doctrine informelle. L’exemple de Galula nous prouve néanmoins qu’une innovation se diffuse beaucoup plus difficilement lorsqu’elle émane des hommes de terrain. / During the last decades, the increasing number of irregular wars brought the modern armies into a delicate situation. In order to overcome this new challenge, these military organizations primarily designed for interstate wars had to innovate. Many historical cases show how certain armies have launched into innovation processes because of new forms of conflict. The case of the French army in Algeria is a good example. The main goal of this paper is to understand how innovation has emerged during the conflict, and how it has diffused within the military organization. A glance at the French strategy in Algeria will allow us to highlight three main innovations: the development of the Revolutionary Warfare doctrine, the creation of “Sections Administratives Specialisées, and the David Galula approach. The analysis of these three study cases shows that innovation came mainly from militaries during the Algerian war, particularly those on top of the hierarchy. However, certain examples of bottom-up innovations do exist. In these cases, diffusion will take place via the informal doctrine. Nevertheless, the Galula example demonstrates that an innovation will diffuse with more difficulty when it comes from people on the ground.

This thesis is a comprehensive investigation of the transport containers produced in Roman Sicily over a chronological period composed of five phases: Early Roman period (30 BC–AD 100); Middle Roman period (AD 100–300); Late Roman period (AD 300–440); Vandal Perios (AD 440/535) and Early Byzantine period (AD 536/600). The research investigates the production and transportation of Sicilian foodstuffs (especially wine) from the major ports of the island to Mediterranean ports and northern Europe. The results demonstrate the wide distribution of Sicilian amphorae and their important role within the wider economy of the Roman Empire. The importance of this research lies in the fact that, despite the agricultural prosperity of Sicily in the Roman Period and its strategic topographical position, transport amphorae remain understudied especially in economic terms. In regards to typology, chronology and distribution, our current knowledge of regional containers has not reached a level comparable to that of amphorae manufactured in other territories. The key discussion focuses on the commercial dynamics of Roman Sicilian amphorae from local, regional and Mediterranean-wide perspectives. The research aims to outline the distribution trends of Sicilian amphorae, looking at the different relative quantities of each amphora type and consequently the extent to which they are present in regions inside and outside Sicily, while considering presences and absences within the more general and homogeneous context of the Mediterranean basin. The organisation of Sicilian amphora production is also tackled through the presentation of probable production sites and excavated kilns. Using these examples, the study investigates the management of production of these containers on the island. The initial data obtained by this research represents a first step in determining differences between Sicilian amphorae workshops producing amphorae — therefore trading wine — for Mediterranean export and manufacturing sites specializing in local/regional trade. Other key achievements include the creation of a new illustrated typology with profile drawings of all the amphora forms and a summary and catalogue of Sicilian amphorae fabrics. In the thesis, the results of archaeometric analysis (thin-sections) carried out on more than 120 Sicilian amphora samples, provided by numerous institutions in Sicily and abroad, are presented. These results add significantly to our knowledge of the fabric composition, manufacture technology, origin and consequently movement of these amphorae around the Mediterranean over six centuries. More generally the research shows that the study of Sicilian material culture along with archaeological evidence is essential for recording the economic dynamics of Sicily, with the intent of dispelling the stereotype that Sicily's primary role was as a grain supplier to Rome. Besides grain — widely produced and exported throughout the imperial period, as attested by ancient sources and inscriptions — the archaeological evidence clearly indicates the export of foodstuffs, especially wine, at an inter-provincial level from the 1^st until the second half of the 6^th century AD.
