A kinetic model of glucose catabolism in Plasmodium falciparum

Penkler, Gerald Patrick 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: Malaria infects over 200 million individuals and leads to the death of over 600 000 people annually. Currently artemisinin combination therapy treatments are effective in treating the disease, but resistance has started to emerge in Cambodia and it is suspected in parts of Vietnam. To maintain the drive to eradicate malaria globally, a great deal of research is aimed at identifying novel prevention strategies, vaccines and antimalarial compounds. Plasmodium falciparum, the most deadly of the malaria parasites, is entirely dependent on glycolysis for ATP. Several of the enzymes within this pathway have been proposed as drug targets and studied in isolation, but the pathway as a whole has not been considered. In this study we employ a bottom up approach for drug target identification in P. falciparum glycolysis. In this thesis we present the biochemical characterisation each of the glycolytic enzymes in P. falciparum trophozoites. The kinetic rate equations, which described the kinetic behaviour of the individual enzymes, were incorporated into a kinetic model. The unfitted model was validated in its ability to predict experimentally measured steady state metabolite concentrations and fluxes as well as the experimental inhibition of the glucose transporter. The validated model provided a tool for drug target identification in P. falciparum glycolysis. Metabolic control analysis and differential control analysis identified the glucose transporter, PfHT1, as a drug target based on its high control of glycolytic flux in the parasite, but low control of flux in the host erythrocyte. This differential control makes the transporter an attractive drug target, as even if both the erythrocyte and parasite glucose transporters are inhibited to the same degree, it is expected that the parasite glycolytic flux would be inhibited to a much greater degree. To demonstrate the differential control of the glucose transporter on the flux and provide further evidence that PfHT1 is an attractive drug target, we investigated the inhibition of the glucose transporter in isolated trophozoites by cytochalasin B. We also measured the inhibition of lactate production flux by cytochalasin B in both isolated P. falciparum trophozoites as well as in erythrocytes. Our findings demonstrated that differential control analysis can be used as a tool for drug target identification and that PfHT1 is an attractive drug target. In this study the fields of biochemistry and systems biology were merged to create a detailed kinetic model of asexual P. falciparum glycolysis and identify several drug targets in the pathway. The model prediction and experimental evidence of differential flux control of the glucose transporter in the host and parasite, has highlighted PfHT1 as a drug target and also demonstrates the strength of differential control analysis in identifying drug targets within a system. The kinetic model is a valuable tool for furthering our understanding of P. falciparum glycolysis and it provides a good foundation for expansion to identify drug targets in the entire central carbon metabolism of P. falciparum. / AFRIKAANSE OPSOMMING: Malaria infekteer meer as 200 miljoen mense en veroorsaak jaarliks tot 600 000 sterftes. Tans is die artemisinien-kombinasieterapie effektief in die bestryding van die siekte, maar weerstandbiedendheid van die parasiet teen die middel blyk reeds ’n merkbare effek in Kambodja en vermoedelik ook in dele van Viëtnam te hê. Om ’n wêreldwye bestryding van malaria moontlik te maak, is ’n groot deel van die huidige navorsing gemik op die identifisering van nuwe voorkomingsstrategieë, entstowwe en malariateenmiddels. Plasmodium falciparum, die dodelikste van die malaria-parasiete, is geheel en al afhanklik van glikolise vir ATP vorming. Verskeie van die ensieme in hierdie metaboliese pad is as teenmiddelteikens voorgestel, en in isolasie bestudeer, maar die pad as ’n geheel is nie bestudeer nie. In hierdie studie het ons ’n ’bottom-up’ benadering vir teenmiddel teikenidentifisering in P. falciparum glikolise gebruik. In hierdie tesis bied ons die biochemiese karakterisering van elk van die glikolitiese ensieme in P. falciparum trofozoïete aan. Die kinetiese vergelykings wat die kinetiese gedrag van die individuele ensieme beskryf, is geintegreer in ’n enkele kinetiese model. Die model waarop geen datapassing toegepas is nie, is gevalideer om eksperimenteel bepaalde bestendige-toestand metabolietkonsentrasies en fluksiewaardes, asook die eksperimentele inhibisie van die glukose transporter, te voorspel. Die gevalideerde model verskaf ’n bykomende hulpmiddel om teenmiddelteikens te identifiseer in P. falciparum glikolise. Metaboliese kontrole-analise en differensiële kontrole-analise het die glukose transporter, PfHT1, as ’n teenmiddelteiken geïdentifiseer, gebaseer op sy hoë kontrole van glikolitiese fluksie in die parasiet, tesame met ’n lae beheer van die glukose transporter op die fluksie in die gasheer eritrosiet. Dié differensiële kontrole maak die glukose transporter ’n aantreklike teenmiddelteiken, want selfs as beide die eritrosiet en die parasiet glukose transporters tot dieselfde mate geïnhibeer word, sal dit steeds ’n hoër glikolietiese fluksieinhibisie van die parasiet tot gevolg hê. Om die differensiële kontrole van die glukose transporter op die fluks te demonstreer en verdere bewyse te lewer dat PfHT1 ’n teenmiddelteiken kan wees, het ons die inhibisie van die glukosetransporter in geïsoleerde trofozoïete deur sitokalasien B ondersoek. Ons het ook die inhibisie van die laktaatproduksiefluksie deur sitokalasien B in beide geïsoleerde P. falciparum trofozoïete sowel as in eritrosiete ondersoek. Ons bevindings bewys dat differensiële kontroleanalise as ’n hulpmiddel vir teenmiddelteikenidentifikasie gebruik kan word en dat PfHT1 ’n aantreklike teenmiddelteiken is. In hierdie studie is die velde van biochemie en sisteembiologie gekombineer om ’n gedetaileerde kinetiese model van ongeslagtelike P. falciparum glikolise te konstueer en verskeie teenmiddelteikens in die metaboliese pad te identifiseer. Die modelvoorspelling sowel as eksperimentele bewyse van die differensiële flukskontrole van die glukose transporter in die gasheer en parasiet het PfHT1 uitgelig as ’n teenmiddelteiken en demonstreer ook die krag van differensiële kontrole analise in die identifisering van teenmiddelteikens binne ’n biologiese stelsel. Die kinetiese model is ’n waardevolle hulpmiddel vir die bevordering van ons begrip van P. falciparum glikolise en dit bied ’n goeie basis vir uitbreiding om teenmiddelteikens in die hele sentrale koolstofmetabolisme van P. falciparum te identifiseer.

An investigation into corporate social investment practices and policies within the South African insurance sector

Egan, Paul 03 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: This is an exploratory study that examines how companies within the South Africa insurance sector approach the area of Corporate Social Investment (CSI). South Africa is burdened with a number of pressing social problems- such as unemployment. HIV/AIDS and crime - and in many respects the insurance industry is on the front-line; as these problems have a direct impact on their core business. The primary research, upon which the findings are based, consist of ten qualitative interviews with individuals who were either responsible for CSI within their organisation or were involved in the decision-making process. Its main aim is to understand the motivations and drivers that underpin corporate giving programmes. In particular, the study focuses on how social investment is managed within the context of a society that is undergoing social transformation. It also touches on the question of self-interest and how this impacts on giving programmes. Notably. the study observed a major shift in how companies set-about their social investments post-1994. These include a more business-like approach in which corporations were managing CSI, a move away from utilizing CSI as a marketing tool, and integrating CSI with other aspects of corporate social responsibility. The research also identified a change in the rationale and philosophies underpinning involvement in CSI. Coupled with this is added external pressure from government and investors, as well as self-imposed drivers arising out of the Financial Sector Charter. / AFRIKAANSE OPSOMMING: Hierdie is 'n ondersoekende studie wat fokus op die benadering van die Suid Afrikaanse versekerings sektor tot die area van Korporatiewe Sosiale Beleggings (KSB). Suid Afrika word geteister deur 'n aantal drukkende sosiale probleme - soos werkloosheid, MIV/VIGS en misdaad - en in baie gevalle is die versekeringsektor in die voorste linie deurdat hierdie kwessies direk impak maak op hul kern besigheid. Die primere navorsing in hierdie verslag is gegrond op tien kwalitatiewe onderhoude met individue wat verantwoordelikheid dra vir KSB binne hul organisasies, of ten minste betrokke is by besluitneming daarrondom. Die hoof doelstelling is om die motivering en drywers te verstaan wat KSB onderspan. In besonder kyk die studie na die bestuur van KSB binne die konteks van 'n samelewing wat sosiale transformasie ondergaan. Die studie raak ook die vraag aan van self-belang en hoe dit impak maak op skenkingsprogramme. Dit is nodig om te let op die punt dat daar 'n groot skuif was in die manier wat maatskappye KSB benader post 1994. Dit sluit 'n sterker besigheidsbenadering in, 'n beweging weg van KSB as 'n bemarkings-instrument, asook die integrasie van KSB met ander aspekte van korporatiewe sosiale verantwoordelikheid. Die studie het ook veranderinge identifiseer in die redes en filosofiee wat dien as grondslag vir KSB. Ook verwant aan dit is die addisionele druk van regering en beleggers, asook die self-opgelegde drywers wat voortspruit uit die Finansiele Sektor Handves.

Strategic options for the physiotherapy industry in the current context of private healthcare in South Africa

Rossouw, Tania 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2006. / ENGLISH ABSTRACT: South Africa's healthcare industry is at a crossroad as pressure in both the public and private sectors is increasing. The extent of change in the industry is overwhelming and it is seen as a very turbulent and unstable environment. Healthcare professionals must reconsider their position in the industry and adapt in this ever-changing environment. The physiotherapy profession forms a small part of the healthcare value chain, but it fulfils an important role in the healthcare system. Unfortunately the profession shows no clear direction and purpose. There also exists a mismatch between the current healthcare environment demands and the physiotherapy service delivery. If they do not adapt in this environment which is in turmoil and have a clear strategy for the way forward, they will be pushed out of the healthcare value chain and become obsolete. The aim of this research report was then to do an in depth analysis of the private healthcare industry in which physiotherapy is operating, to analyse the external physiotherapy industry and an internal analysis of the profession so as to construct a generic strategy for the physiotherapy profession in the private healthcare sector in South Africa. To achieve this aim, it was determined that qualitative, investigative research would be conducted. The research methodology used in this research report was a combination of primary and secondary research. Firstly, secondary research in the form of a literature review was conducted to provide a comprehensive insight into the provision of health care in South Africa. Thereafter, primary research was conducted through semi-structured, in-depth interviews with a purposive sample of physiotherapy industry experts to analyse the external physiotherapy Industry as well as the internal profession environment. Main findings include that the physiotherapy industry is becoming less attractive as competitive forces in the physiotherapy and private healthcare industry are moderate to strong. Deconstruction of the healthcare value chain in the private sector is increasing intra- and inter-professional competition. Government plays a major role in the attractiveness of the industry as they are restricting competitive and market forces and minimising profits through legislation. Medical schemes are trying to contain costs and managed healthcare is coming to the forefront. The physiotherapy market is stagnating and the clients' needs and requirements are changing. Opportunities that were identified we~e the expansion into new markets, involvement in other industries and broadening the scope of practice. Threats are mainly from governmental legislation and policies, vertical integration from the hospital and medical scheme industries and the threat of substitutes, especially alternative health. From the internal profession analysis a current strategy was identified and a strategic intent was formulated as the physiotherapy profession wants to be the preferred and relevant health care service provider in prevention, management and rehabilitation of potential and actual movement impairments of individuals. Strengths to help build this vision included their high regard and profile, quality training, increase in research and evidence and their whole service package. Weaknesses that must be overcome include poor business, managerial and marketing skills, limited role models and leaders and the high levels of intra-professional competition leading to the demise of the profession. Having completed the analysis, major strategic thrusts with a focussed differentiated approach for the profession could then be formulated: • Define physiotherapy and the scope of practice. • Reinstate physiotherapy in the healthcare system. • Develop leadership. • Cooperate within the profession. • Maintain professional autonomy. • Develop business skills. / AFRIKAANSE OPSOMMING: Gesondheidsprofessies moet hul posisie in die industrie herevalueer en aanpas in hierdie steeds wisselende omgewing. Die fisioterapie professie beslaan 'n klein deeltjie van die gesondheidsorg waardeketting, maar dit vervul 'n baie belangrike rol in die gesondheidsorg stelsel. Ongelukkig blyk dit asof die professie geen rigting en doeleindes het waarna dit beweeg en streef nie. Verder bestaan daar ook 'n wanbelyning tussen die huidige gesondheidsorg omgewingvereistes en die dienste wat fisioterapie verrig. Indien die fisioterapie professie nie aanpas in hierdie onstuimige omgewing nie en 'n duidelike strategie ontwikkel vir die toekoms nie, staan dit in gevaar om te verval uit die gesondheidsorg-waardeketting en te vergaan. Die doel van hierdie navorsingswerkstuk is dan om 'n in diepte analise te doen van die privaat gesondheidsorgindustrie waarin fisiolerapeute funksioneer, om die eksterne fisioterapie-industrie sowel as die interne professie te analiseer; ten einde 'n generiese strategie vir die fisiolerapie-professie in privaat gesondheid in Suid Afrika te ontwikkel. Om hierdie doelwitte te bereik is daar besluit om kwalitatiewe navorsing te doen. Die navorsingsmetodologie wat gebruik is bestaan uit 'n kombinasie van primere en sekondere navorsing. Sekondere navorsing is gedoen in die vorm van 'n literatuuroorsig om 'n omvattende oorsig te gee van die gesondheidsorg dienslewering in Suid Afrika. Daarna is primere navorsing gedoen in die vorm van gedeeltelike gestruktureerde, in diepte onderhoude met 'n doelbewuste steekproef van fisioterapie-kundiges om die eksterne omgewing en interne professie te evalueer. Hoof bevindings uit die analise is dat die fisioterapie-industrie se aantreklikheid besig is om te verminder as gevolg van gemiddelde tot sterk kompeterende kragte. Dekonstruksie van die gesondheidsorg-waardeketting in die privaatsektor lei tot verhoogde intra- en inter-professionele kompetisie. Die regering speel ook 'n groot rol in die aantreklikheid van die industrie en hulle beperk natuurlike kompetisie en markkragte en minimaliseer winste deur middel van wetgewing. Mediese fondse probeer kostes beperk en besturende gesondheidsorg begin ontluik. Die huidige fisioterapiemark is besig om te stagneer en kliente se behoeftes en vereistes is besig om te verander. Geleenthede wat geidentifiseer is sluit in die uitbreiding na nuwe markte, betrokkenheid by ander industrie; en die verbreding van fisioterapie se bestek van praktyk. Bedreigings bestaan hoofsaaklik vanaf regeringswetgewing en regulasies, vertikale integrasie van die hospitaal en mediese fonds industriee en die bedreiging van plaasvervangers, veral alternatiewe gesondheid. Vanaf die interne professie-analise is daar 'n huidige strategie geidentifiseer en 'n strategiese intensie kon geformuleer word. Hierdie intensie is dat die fisioterapieprofessie die gewenste en relevante gesondheidsorg diensverskaffer sal wees in die voorkoming, bestuur en rehabilitasie van potensiele en werklike bewegingsaantastings van individue. Sterkpunte in die professie wat hierdie intensie kan ondersteun, sluit in hul goeie profiel en agting, kwaliteit opleiding, toename in navorsing en hul volledige dienspakket. Swakpunte wat oorkom moet word is swak besigheids-, bestuur - en bemarkingsvaardighede, beperkte rolmodelle en leiers en die intra-professionele kompetisie wat die professie as 'n geheel ondermyn. Nadat die analise gedoen is kon daar hoof strategiese rigtings geformuleer word met 'n gefokusde differensiasie benadering: • Definieer fisioterapie en bestek van praktyk. • Hervestig fisioterapie in die gesondheidsorgstelsel. • Ontwikkel leierskap. • Samewerking in die professie. • Behou professionele outonomiteit. • Ontwikkel besigheidsvaardighede.

A national electronic database of special music collections in South Africa

De Jongh, Martha Susanna 03 1900 (has links)
Thesis (MMus (Music))--University of Stellenbosch, 2009. / In the absence of a state-sponsored South African archive that focuses on collecting, ordering, cataloguing and preserving special music collections for research, the Documentation Centre for Music (DOMUS) was established in 2005 as a research project at the University of Stellenbosch. Music research in South Africa is often impeded by inaccessibility of materials, staff shortages at archives and libraries, financial constraints and time-consuming ordering and cataloguing processes. Additionally there is, locally, restricted knowledge of the existence, location and status of relevant primary sources. Accessibility clearly depends on knowing of the existence of materials, as well as the extent to which collections have been ordered and catalogued. An overview of repositories such as the Nasionale Afrikaanse Letterkundige Museum and Navorsingsentrum (NALN), the now defunct National Documentation Centre for Music and the International Library of African Music (ILAM) paints a troubling picture of archival neglect and disintegration. Apart from ILAM, which has a very specific collecting and research focus, this trend was one that ostensibly started in the 1980s and is still continuing. It could be ascribed to a lack of planning and forward thinking under the previous political dispensation, aggravated by policies of transformation and restructuring in the current one. Existing sources supporting research on primary materials are dated and not discipline-specific. Thus this study aims to address issues of inaccessibility of primary music materials by creating a comprehensive and ongoing national electronic database of special music collections in South Africa. It is hoped that this will help to alert researchers to the existence and status of special music collections housed at various levels of South African academic and civil society.

Die institusionele beeld en die impak daarvan op die kommunikasie binne die Universiteit van Stellenbosch

Pienaar, Marguerite 03 1900 (has links)
Thesis (MPhil (Afrikaans and Dutch. Document Analysis))--University of Stellenbosch, 2007. / In this study, research has been done on the institutional image of the Stellenbosch University (SU). The impact of the true and desired image on the written communication of the SU has been researched to determine how much influence the US can have on the forming of the institutional image and how it can be improved to correlate more with the desired image of the SU. The focus was, more specifically, on the written communication of the Registrar’s division of the SU and their institutional documents. The institutional image was tested by means of questionnaires filled in by the students of the SU. The groups have been selected in accordance with the population profile of the SU to be statistically representitave of the true population studying at the SU.

Die balans tussen die ekspressiewe en relasionele boodskappe in donasiebriewe van die Universiteit Stellenbosch : ‘n ondersoek na die effek daarvan op beeldvorming

Van Wyk, Anica 03 1900 (has links)
Thesis (MPhil (Afrikaans and Dutch))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: In this study the balance between relational and expressive messages on the image formation and projection of a document is studied. To study the effect of these messages, a case study was done on one of the donation letters of Stellenbosch University (SU). The purpose of the research was firstly to established what the image formation and projection of the SU was. The quality of the SU’s image and communication had to be determined. Secondly, the degree of attachment between die SU and respondents was measured to see if it had any influence on the way that they perceived the SU. The IFP-model (Image Formation and Projection model) served as a theoretical basis for the study – the model postulates that various document design aspects and concepts such as image, identitity and culture influence each other. The model was then used to a) identify problematic areas in the documentation b) form the basis of the questionnaire and c) explain the connection between the image formation and projection, and the style aspects in die document. The third goal of the research was to operationalize the relational and expressive messages by manipulating specific style aspects. The researcher had determined that the two messages were imbalanced in the original donation letter, to the extent that the reader did not have any real ‘presence’ in the document. The researcher then proceeded to design a second version of the donation letter, but with the relational and expressive messages brought into balance. Alumni of the SU were chosen as respondents for the study. The Stellenbosch Foundation distributed the questionnaires, along with the two versions of the letter. The researcher had decided upon e-mail as a distribution channel to discount any geographical bias. Two variables were used: Race (coloured and white persons) and age. Younger than 35 years of age, and 35 years of age or older than 35 were chosen as arbitrary cutoff points for respondents. The results were processed statistically so that trends and data could be displayed clearly. Results showed that alumni do have a positive image of the SU, as well as its communication. Alumni also feel reasonably connected to the SU. A strong preference was however shown for the redesigned donation letter, wherein the two messages are balanced out. This means that the SU’s image is projected in a more positive way in a document where the reader has a bigger presence. / AFRIKAANSE OPSOMMING: In hierdie studie is daar ondersoek watter invloed ‘n wanbalans tussen die relasionele en ekspressiewe boodskappe in ‘n dokument op die beeldvorming en projeksie van daardie dokument het. Vir hierdie ondersoek is een van die Universiteit Stellenbosch (US) se donasiebriewe as gevallestudie gebruik. Die doel van die navorsing was eerstens om te bepaal hoe die beeldvorming enprojeksie van die US daar uitsien. Daar moes dus vasgestel word hoe gunstig die beeld van die US is en wat die opvatting oor die US se kommunikasie is. Tweedens is gepoog om die graad verbondenheid en verhouding tussen die US en die respondente te meet, om te sien of dit ‘n invloed het op hoe hulle die US sien. Die IFP-model (Image Formation and Projection) dien as ‘n teoretiese basis vir die studie – die model postuleer dat verskeie dokumentontwerp-aspekte en konsepte soos beeld, identiteit en kultuur, ‘n wedersydse invloed op mekaar het. Die model is dus gebruik om a) probleemareas in die dokument te identifiseer, b) die basis van die vraelys te vorm, en c) die verband tussen die beeldvorming en projeksie van die US, en die stilistiese aspekte te verduidelik. Die derde doel van die navorsing was om die relasionele en ekspressiewe boodskappe te operasionaliseer in verskeie stylaspekte, sodat dit gemanipuleer kan word. Die navorser het bepaal dat daar ‘n wanbalans bestaan tussen die twee boodskappe in die oorspronklike donasiebrief, en dat hierdie wanbalans veroorsaak dat die leser nie werklik ‘n ‘teenwoordigheid’ in die dokument het nie. Om die effek van hierdie wanbalans te toets, is ‘n tweede weergawe van die brief ontwerp, waarin die twee boodskappe in balans gebring word. Alumni van die US is as teikengroep gekies vir die studie. Die Stellenbosch Stigting het vraelyste, tesame met die twee weergawes van die donasiebrief aan hulle gestuur. Die navorser het besluit op e-pos as ‘n distribusiemetode om enige geografiese bevooroordeeldheid te voorkom. Die twee veranderlikes was ras (bruin en wit persone) en ouderdom. Jonger as 35, en 35 of ouer as 35 is gekies as arbitrêre afsnypunt vir respondente. Die resultate is statisties verwerk om duidelike tendense en data te bekom. Resultate het getoon dat die alumni wel ‘n positiewe beeld van die US het, asook sy kommunikasie. Alumni voel ook nog redelik verbonde aan die US. ‘n Voorkeur is egter getoon vir die herontwerpte brief, d.w.s. waar die balans tussen die boodskappe eweredig is. Dit dui aan dat die US se beeld beter uitgedra sal word (of op ‘n positiewer wyse) as die leser ingetrek word deur die teks.

The relevance, importance and applicability of corporate social and environmental responsibility: South African case studies

Louw, Marie-Louise 03 1900 (has links)
Thesis (MPhil (Sustainable Development Planning and Management))--University of Stellenbosch, 2007. / At the beginning of the new millennium, the world faces various challenges. Global warming is an all too familiar word, global terrorism is a threat to many countries that always felt safe and an ever looming oil crisis just does not want to go away. No longer can it be argued that nature is a never-ending provider of resources. In order for humanity to co-exist with nature, it is of great importance that we take our responsibility towards nature and other human beings seriously. In the midst of all these, the most prominent institution in the world, the corporation, plays a very significant role. They are the biggest traders in resources and they are also the institutions that affect our lives more than any other. It is because of the influence that corporations have in our lives and on the natural environment they operate in, that they need to take their social and environmental responsibility serious. This thesis focuses on the corporate social and environmental responsibility of two prominent corporations that operate in and around Stellenbosch: the University of Stellenbosch and Spier Holdings. The validity of the reasons behind corporate social responsibility is also investigated through literature before it is “tested” at the two corporations mentioned above. In terms of its findings, the thesis established the effectiveness of the way the university is dealing with social and environmental issues. Opposed to this, Spier is studied as a corporation that deals with the same challenges in an environmental and socially sensitive manner. The thesis also shows that there is a moral and business case for corporate social and environmental responsibility that is applicable to corporations in general and that those reasons are valid and relevant. The thesis found that becoming a more sustainable corporation is beneficial for the corporation, the society in which it operates as well as the natural environment.

Lessons from good to great to enhance 1Time's operations and business sustainability

Somandass, Rajendra 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This qualitative study is anchored on Jim Collins' business bestseller entitled, "Good to Great: Why Some Companies Make the Leap ... & Others Don't". It draws on its main business paradigms and models designed to help firms to make the quantum leap from not only being "good", but to become "great" world class performers and brands if they follow his dictums and business advocacy in overcoming obstacles and archaic business thinking. I have chosen for this dissertation, South Africa's latest low~cost carrier (Lee), "I Time", which has just entered this lucrative but highly competitive aviation industry dominated by SAA and with a small market share fought over by Kulula, the very first Lee challenger. It is a 000- empirical case study as it is focused on 1 Time and with a solo interview drawn from Glenn Orsmond and augmented by research data glimpsed from the company and also the media and other sources. After the introduction and overview, from Chapter 3 onwards, in each of the chapters, my approach is to highlight the Collins key business models [and in some cases, interspersed with other models drawn from other business writers] that help companies to migrate from good to great covering such determinants as leadership, corporate culture, human asset, technology, competitive strategies and so on. This is then interwoven with the strategic thoughts of Glenn Orsmond, the CEO of "1 Time" low·cost budget carrier whom I managed to interview for this thesis and supplemented with my own research inputs and analysis. I conclude this study with highlights and recommendations as to how "I Time" can achieve this long-term objective, as it is a new entrant and challenger, hence riding the learning curve and competing with the traditional carrier, SAA as well as Kulula, the major Lee. The challenge now is for 1 Time to enter into the "Good" loop and then take drastic as well as incremental steps to migrate to "Great," the highest aspiration for companies that are prepared for long term survival built on a lasting set of strategies. Collins has termed good as the nemesis of great and thus entrepreneurs and CEOs need to have a deep understanding of the underlying principles and determinants in their great leap forward by thinking aloud that good is merely average. / AFRIKAANSE OPSOMMING: Die volgende kwalitatiewe studie is gebaseer op die topverkoper van Jim Collins getiteld. "Good to Great: Why some companies make the leap ... & others don't" USA: Harpers Business 2001. Die uitsprake en besigheidsbeginsels van Collins help besighede om die brug tussen "goed" en "onverbeterlik" te oorbrug. As die inhoud van bogenoemde uitsprake en besigheidverbeteringe en aanbevelings nagekom word, sal verouderde besigheiddenke en ander struikelblokke verwyder word sodat die volgende stelling van pas is. Ek het vir hierdie proefskrif "I Time", Suid-Afrika se nuutste lae koste vlug vrag draer gekies. "1 Time" het so pas hierdie winsgewende en hoogs kompeterende mark betree, wat tot dusver gedomineer is deur SAL, en 'n ander klein vlugvragdraer, naamlik Kulula, wat die eerste lae koste vlug vrag draer was. Die gevalle studie is nie gebaseer op absolute besigheidsteorie nie, maar fokus sIegs op " I Time", met 'n persoonlike onderhoud wat met Glenn Ormond gevoer is en uitgebrei is deur navorsings data wat aan my voorsien deur "1 Time" asook deur die media en ander bronne. Die benadering wat deurentyd gevolg word, vanaf hoofstuk 3, is Collins se sleutel besigheidsmodelle uit te lug en te koppel met [in sommige gevalle, ander besigheidsskrywers se modules] wat maatskappye help om te migreer van goed na uitsonderlik en determinante soos leierskap, korporatiewe kultuur, menslike hulpbronne, tegnologie, kompeterende strategie dek en so voorts. Dit is dan geinterweef in strategiese denke van Glen Orsmond, die Hoof Uitvoerende Beampte van "1 Time" lae-koste begroting draer waar ek die kans gehad het om 'n onderhoud te voer vir hierdie proefskrif ondersteun deur my eie navorsing en analise. Ek sluit die studie af met uitgeligte punte en aanbevelings hoe "1 Time" hulle langtermyn doelwitte kan bereik, siende dat hulle die mark as nuweling betree en bekend wil wees as die nuutste aanspraakmaker in die lae-koste vlugvrag draer industrie, sal hulle bereid moet wees om die lae kurwe te moet deurloop terwyl hulle kompeteer met SAL en Kulula, die huidige hoof kompetisie in die lae-koste draer bedryf, Die ommiddellike uitdaging vir "1 Time" is om die "Goeie" situasie te betree en dan met inkrimentele stappe te migreer na die "Onverbeterlike" vlak, die hoogste aspirasie vir maatskappye wat voorbereid is om hulle lang termyn bestaan wat op volgehoue besigheids strategie gebaseer is te behou. Collins bepaal dat die "Goeie" vlak die wraakgodin is van die "Onverbeterlike" vlak en dat CEO's en ondernemers moet waak om 'n diep verstandhouding van die grondbeginsels en beslissende faktore in hulle tog in hulle groot sprong voorentoe en dat die "goeie" vlak moet gesien word as 'n onaanvaarbare gemiddelde prestasie.

An overview of the development of the German and UK labour dispute resolution systems and assessment of their respective strengths and weaknesses

Sponagel, Moritz 03 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2006. / ENGLISH ABSTRACT: In many countries in the world today, Labour Courts have developed as an integral part of the law system arising from the need to afford labour disputes specialised adjudication, independent from the ordinary civil courts. This study presents a comparison of the German Labour Court System and the British Employment Tribunal System, representing the Continental Law System and the Common Law System respectively. In comparing the German Labour Courts and the British Employment Tribunals, the study highlights the special qualities of labour law and why labour disputes are treated differently from other legal disputes. It demonstrates that both systems have attempted to achieve the handling of labour disputes in different ways and proceedings. Similarly, the study reveals that both systems have their pros, cons and limitations and that no system can guarantee an optimal way to achieve a "better" justice. Nonetheless, the study attempts to show that each system can learn from the other's strengths and weaknesses by being open and reasonable to criticism. Another important objective of this study is to determine whether Labour Courts and Employment Tribunals should be maintained as a separate part of the law system or whether to merge them into the ordinary civil courts as some critics feel that such courts and tribunals create added expenses to governments. Furthermore, the study explores other dispute resolution mechanisms that if encouraged, provide additional benefit to labour issues in teoday's complex business environment. As a whole, the study proves that the German Labour Courts and British Employment Tribunals are a quicker, cheaper and better way of achieving justice, preferable to the civil litigation system. It is therefore concluded that such courts and tribunals should be maintained because of their significant successes so far. Furthermore, it is suggested that labour dispute resolution can be further developed through the increased use of mechanisms such as conciliation, negotiation and mediation in the management of organizations today. / AFRIKAANSE OPSOMMING: In baie lande van die wereld vandag, het gespesialiseerde arbeids tribunale ontwikkel as 'n integrale deel van die regsisteem as gevolg van die behoefte om arbeidsdispute te onderwerp aan gespesialiseerde beregting, onafhanklik van gewone siviele howe. Hierdie studie behels 'n vergelyking van die Duitse Arbiedshofsisteem en die Britse "Employment Tribunal" sisteem, wat die kontinentale regsisteem en 'n gemeenregtelike regsisteem respektiewelik verteenwoordig. Deur die Duitse Arbeidshowe en die Britse "Employment Tribunals" te vergelyk, beklemtoon hierdie studie die spesiale eienskappe van arbeidsreg en waarom arbeidsdispute anders as andere regsdispute hanteer word. Dit demonstreer dat beide sisteme probeer het om die hantering van arbeidsdispute op verskillende maniere en deur middel van verskillende prosesse te bereik. Terselfdertyd, wys die studie dat beide sisteme hulle voordele, nadele en tekortkomings het, en dat nie een sisteem 'n optimale manier het om "beter" geregtigheid tussen werkgewer en werknemer te laat geskied nie. Nietemin, probeer die studie wys dat elke sisteem kan leer van die ander se sterktepunte en tekortkominge. 'n Verdere belangrike doel van hierdie studie is om te bepaal of die Duitse Arbeidshowe en Britse "Employment Tribunals" as aparte deel van die regsisteem behoort te voortbestaan, of hulle saamgesmelt moet word met die gewone siviele howe, want sekere kritici voel dat sulke howe en tribunale addisionele koste vir owerhede meebring. Verder ondersoek die studie ander dispuutoplossings meganismes, wat, indien dit bevorder sou word, dalk addisionele voordele in vandag se komplekse besigheidsomgewing kan meebring. In geheel toon hierdie studie dat die Duitse Arbeidshowe en Britse "Employment Tribunals" 'n vinniger, goedkoper en beter manier bied om geregtigheid te bereik en verkies word bo die siviele litigasie sisteem. Die gevolgtrekking is dat sulke howe en tribunale behou moet word as gevolg van hulle sukses tot dusver. Verder word dit voorgestel dat arbeidsgeskilbeslegting verder ontwikkel kan word deur groter gebruik te maak van meganismes soos konsiliase, onderhandeling en mediasie in organisasies.
