A kinetic model of glucose catabolism in Plasmodium falciparumPenkler, 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 sectorEgan, 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 AfricaRossouw, 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 AfricaDe 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 StellenboschPienaar, 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 beeldvormingVan 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 studiesLouw, 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 sustainabilitySomandass, 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

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

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 weaknessesSponagel, 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.
