‘n Teoretiese en praktiese ondersoek na ‘n betroubare en toepaslike boedelbeplanningsmodel

Thesis (LLM)--Stellenbosch University, 2004AFRIKAANSE OPSOMMING : Hierdie studie handel oor ‘n teoretiese en praktiese ondersoek van die vakdissipline boedelbeplanning met die oog daarop om ‘n betroubare en toepaslike boedelbeplanningsmodel te identifiseer. Die ondersoek word vir doeleindes van hierdie studie beperk en afgebaken tot die ontwikkeling van so ‘n model vir ‘n persoon wat homself in die nis van die gemiddelde salaristrekker bevind met die fokus op ‘n toepaslike finansiële beplanning vir die intrede van dié se dood. Daar word ondersoek ingestel na die basis waaruit dié vakdissipline ontstaan en ontwikkel het. Daar is gevind dat die metode van erfopvolging daardie basis uitmaak en ook ‘n integrale deel vorm van enige boedelbeplanning wat onderneem word. Relevante beginsels en die metodes van erfopvolging soos dit in die Romeinse, Romeins-Hollandse en Engelse erfreg gegeld het, word ontleed. Met die historiese ontwikkeling in hierdie stelsels as agtergrond, word daar by die Suid-Afrikaanse erfreg aangesluit en die posisie volgens die Suid-Afrikaanse reg bepaal. Die teoretiese grondslag van die vakdissipline word ook vasgelê. Die verskillende rolspelers betrokke by die voorgestelde boedelbeplanningsproses word geïdentifiseer en die voorgestelde boedelbeplanningsproses word beskryf. Die boedelberedderingsproses word ook binne die konteks van die Engelse reg met dié proses binne die konteks van die Suid-Afrikaanse reg deur ‘n regsvergelykende studie vergelyk. Hierdie ondersoek word ook beperk tot daardie aspekte van die beredderingsproses wat vir doeleindes van boedelbeplanning van belang is, juis in die lig van die invloed van die Engelsregtelike reëls op die Suid-Afrikaanse reg ten aansien van gemelde proses. Praktiese probleme wat tans tydens die beredderingsproses van bestorwe boedels deur trustmaatskappye ervaar word, word ook geïdentifiseer en ontleed. Hierdie probleme ondersteun ook die behoefte aan die identifisering van ‘n betroubare en toepaslike boedelbeplanningsmodel. Die identifisering van ‘n toepaslike boedelontledingsmodel word aangetoon as ‘n onontbeerlike kontrolemeganisme van die voorgestelde boedelbeplanningsmodel. Hierdie ontledingsmodel word ook uitgebrei om probleemareas ten aansien van verskillende scenario’s uit te wys met ‘n bepaalde konvensionele gesinskonstruksie as die basis vir die ontledingsmodel. Beskikbare boedelbeplanningsinstrumente en –tegnieke word geïdentifiseer as hulpmiddels om die erflater se toepaslike boedelplan ingevolge die struktuur van die voorgestelde boedelbeplanningsmodel te fasiliteer. Testamentêre meganismes word van inter vivos meganismes onderskei en toepaslike wetgewing word ook bespreek. Na aanleiding van die resultate van hierdie navorsing word ‘n betroubare en toepaslike boedelbeplanningsmodel geïdentifiseer. Die studie word afgesluit met ‘n beoordeling en samevatting van die resultate van die navorsing met ‘n spesifieke verwysing na die implementeringsfase van ‘n boedelplan en die gereelde hersiening daarvan.ENGLISH ABSTRACT : This study deals with a theoretical and practical investigation of the subject discipline of estate planning in order to identify a reliable and appropriate estate planning model. For purposes of this study, the investigation is restricted to the development of such a model in respect of a person within the niche of an average salary earner with the focus on an appropriate financial planning in respect of his death. An investigation is conducted into the basis from which the subject emerged and developed. It is determined that this basis is the method of succession and that it also forms an integral part of any proposed estate planning. Relevant principles and the methods of succession which were in force in the Roman, Roman-Dutch and English law of succession are analysed. Through the historic development, against the background of these systems, a link is made to the South African law of succession and the position in terms of the South African law is determined. The theoretical basis of the subject discipline is also laid down. The different role players involved are identified in the process and the proposed estate planning process is identified and described. The administration of estates process within the context of the English law is compared with the same process in the context of the South African law through a comparative study. This investigation is limited to those aspects of the administration of estates process important for purposes of estate planning, especially in view of the influence that the rules of the English law had on the South African law in respect of this process. Practical problems currently experienced by trust companies in respect of the administration of estates are also identified and analysed. These problems also indicate the need for the identification of a reliable and appropriate estate planning model. The identification of an appropriate estate analysis model is identified as an essential control mechanism for the proposed estate planning model. This model is furthermore expanded in order to point out the problem areas in respect of different scenarios with a determined conventional family construction as the basis for the analysis. Available estate planning instruments and techniques are identified as aids in order to facilitate the testator’s estate plan by virtue of the proposed estate planning model. Testamentary mechanisms are distinguished from inter vivos mechanisms and applicable legislation is discussed. A reliable and appropriate estate planning model is identified, bearing in mind the results of the research conducted. This study is concluded with an adjudication and consolidation of the results of the research with a special reference to the implementation phase of an estate plan and the frequent revision thereof

A descriptive investigation of the ultrastructure of fibrin networks in thrombo-embolic ischemic stroke

Stroke is one of the leading causes of death worldwide. Formation of a fibrin clot is controlled by a group of tightly regulated plasma proteases and cofactors and a change in the fibrin fiber formation causes an alteration in clot morphology. This plays an important role during thrombotic events. In the current study we investigated the ultrastructure of fibrin networks from fifteen ischemic stroke patients by using scanning electron microscopy. Clot morphology was investigated with and without the addition of human thrombin to the platelet rich plasma. Previously it was shown that, when studying the ultrastructure of fibrin networks, the addition of thrombin is necessary to form an expansive, fully coagulated layer of fibers. Results from the addition of thrombin to the plasma showed thick, matted fibrin fibers and a net covering some of the major fibers in stroke patients. Typical control morphology with major thick fibers and minor thin fibers could be seen in some areas in the stroke patients. In stroke patients, without the addition of thrombin, a matted fibrin network still formed, indicating that the factors responsible for the abnormal fibrin morphology are present in the circulating plasma and is the cause of the observed matted, layered morphology. This is not present in healthy individuals. From the results obtained we suggest that this changed morphology might be useful in a screening regime to identify the possibility of a stroke or even to follow the progress of stroke patients after treatment.http://link.springer.com/journal/11239hb2017Anatomy and PhysiologyNeurolog

Critical management studies in South Africa

This book shows how Critical Management Studies (CMS) scholarship is starting to develop a character of its own in South Africa. It attests to CMS slowly gaining momentum and acquiring an identity of its own amongst South African scholars. However, management studies in South Africa is dominated by capitalist ideology and positivist methodology. Although Interpretive scholarship has gained some momentum, it still falls within the parameters of ‘mainstream’, capitalist thinking. Scholarship outside the domain of capitalist thinking, such as critical scholarship, remains sorely underexplored. Being entrenched in the positivist tradition is arguably a major Achilles’ Heel for the progression of management as a field of inquiry. CMS presents a vehicle for alternative epistemologies to be heard in the management discourse. With its focus on power imbalances, struggles for emancipation from oppression, and distrust of capitalism, CMS provides the peripheral point of view with a voice. CMS presents a space where scholars can engage with South African realities surrounding political, cultural, social, and historic contexts and issues in management. This book is promoting CMS to the scholarly community, to show that there are exciting possibilities being offered by a different approach to management scholarship. This book also forms part of a larger project of growing CMS in South Africa, and is a collection of original works by academics actively working in CMS, following various methodological approaches which can be categorised into two broad methodological categories, namely, conceptual work and empirical work following an Interpretive approach

Seasonal diet changes in elephant and impala in mopane woodland

Abstract Elephant and impala as intermediate feeders, having a mixed diet of grass and browse, respond to seasonal fluctuations of forage quality by changing their diet composition. We tested the hypotheses that (1) the decrease in forage quality is accompanied by a change in diet from more monocots in the wet season to more dicots in the dry season and that that change is more pronounced and faster in impala than in elephant; (2) mopane (Colophospermum mopane), the most abundant dicot species, is the most important species in the elephant diet in mopane woodland, whereas impala feed relatively less on mopane due to the high condensed tannin concentration; and (3) impala on nutrient-rich soils have a diet consisting of more grass and change later to diet of more browse than impala on nutrient-poor soils. The phosphorus content and in vitro digestibility of monocots decreased and the NDF content increased significantly towards the end of the wet season, whereas in dicots no significant trend could be detected. We argue that this decreasing monocot quality caused elephant and impala to consume more dicots in the dry season. Elephant changed their diet gradually over a 16-week period from 70% to 25% monocots, whereas impala changed diets rapidly (2-4 weeks) from 95% to 70% monocots. For both elephants and impala, there was a positive correlation between percentage of monocots and dicots in the diet and the in vitro digestibility of these forage items. Mopane was the most important dicot species in the elephant diet and its contribution to the diet increased significantly in the dry season, whereas impala selected other dicot species. On nutrient-rich gabbroic soils, impala ate significantly more monocots than impala from nutrient-poor granitic soils, which was related to the higher in vitro digestibility of the monocots on gabbroic soil. Digestibility of food items appears to be an important determinant of diet change from the wet to the dry season in impala and elephants

Binomial option pricing models for real estate development

Purpose: The purpose of this paper is to construct option pricing models for real estate development by considering and incorporating institutional arrangements, direct interactions and financial constraints in the model. It extends the application of real option theory from the framework borrowed from financial option pricing, and considers the case where a development company has restrictions from outside environment and financial constraint. It explores the effects of these additional practical factors on real asset project value and development timing. This paper makes contributions to bridge the theoretical models and practical applications. Design/methodology/approach: Real estate development is modelled in the binomial option pricing framework with the considerations of time-to-build, foregone rent if delaying, institutional environment and capital budgeting. The investment timings are derived from the models and sensitivity analysis is conducted to explore the effects of these factors. Findings: Apart from the factors in traditional option pricing theory, this paper confirms that the contractual covenants, positive synergies between properties and financial status of the firm, which enhance or restrict real flexibility embedded in the development land, influence project value and investment timing. Numerical examples illustrate the effects of these factors. It is argued that the valuation of real options should place emphasis on industry-specific characteristics and start from the perspective of the firm rather than individual options. Practical implications: The models constructed in this paper and the results can be directly used in the practical real estate development. Originality/value: This paper incorporates many practical factors in real estate development which are not investigated in previous studies. It values the option project from the firm perspective rather than project perspective as previous studies. It also shows the effects of institutional arrangement and firm factors on project value and development timing
