‘Something Out of the Way’: Edmund Gosse’s Biography of Henrik Ibsen
No full textIn 1907, Edmund Gosse published two biographies, Father and Son: A Study of Two Temperaments and Henrik Ibsen. In her chapter on Edmund Gosse’s biography of Henrik Ibsen, Suze van der Poll examines how far we can say that Gosse’s Father and Son functions as a source of inspiration for Henrik Ibsen. Looking more closely at the structural principles of the work and Gosse’s presentation of temperament and his use of narrative techniques, she demonstrates that the English biographer’s portrait not only shapes Ibsen as a canonical European author and citizen of the world, but at the same time reflects Gosse’s own development, as both human being and literary critic
Control room agents : an information-theoretic approach
No full textIn this thesis, a particular class of agent is singled out for examination. In order to provide
a guiding metaphor, we speak of control room agents. Our focus is on rational decision-
making by such agents, where the circumstances obtaining are such that rationality is
bounded. Control room agents, whether human or non-human, need to reason and act
in a changing environment with only limited information available to them. Determining
the current state of the environment is a central concern for control room agents if they
are to reason and act sensibly. A control room agent cannot plan its actions without
having an internal representation (epistemic state) of its environment, and cannot make
rational decisions unless this representation, to some level of accuracy, reflects the state
of its environment. The focus of this thesis is on three aspects regarding the epistemic
functioning of a control room agent:
1. How should the epistemic state of a control room agent be represented in order to
facilitate logical analysis?
2. How should a control room agent change its epistemic state upon receiving new
information?
3. How should a control room agent combine available information from different
sources?
In describing the class of control room agents as first-order intentional systems hav-
ing both informational and motivational attitudes, an agent-oriented view is adopted.
The central construct used in the information-theoretic approach, which is qualitative in
nature, is the concept of a templated ordering.
Representing the epistemic state of a control room agent by a (special form of) tem-
plated ordering signals a departure from the many approaches in which only the beliefs
of an agent are represented. Templated orderings allow for the representation of both
knowledge and belief.
A control room agent changes its epistemic state according to a proposed epistemic
change algorithm, which allows the agent to select between two well-established forms of
belief change operations, namely, belief revision and belief update.
The combination of (possibly conflicting) information from different sources has re-
ceived a lot of attention in recent years. Using templated orderings for the semantic
representation of information, a new family of purely qualitative merging operations is
developed.Ph. D. (Computer Science)School of Computin

An integrated framework of environmental management accounting practices to promote greener gold mining in Zimbabwe
No full textAbstracts in English, Zulu and AfrikaansAlthough the Zimbabwean gold mining industry has been praised for its positive contributions to economic growth, it has also come under fire for harming local communities through forced evictions and forced relocation of communities without providing adequate compensation, pollution of water and air, loss of grazing and agricultural land, the creation of unprotected pits, and exploitation and depletion of natural resources. The literature has identified material flow cost accounting (MFCA), life cycle costing (LCC) and activity-based costing (ABC) as essential environmental management accounting practices (EMAPs) to manage the environment. The EMAPs tend to be discussed in isolation hence the need to integrate them. Current frameworks fail to direct sustainability in organisations, opening calls for new approaches that integrate sustainability into business processes. The study was motivated by a lack of studies on the importance of EMAPs, noted in developing countries. Due to the existing frameworks' failure to address environmental challenges, practical means and techniques for businesses to integrate, measure and communicate environmental issues remain challenging. Existing frameworks have been observed as lacking industry scale, besides failing to describe how to achieve the integration of sustainability. Research questions and research objectives were developed from the problem statement. Institutional, stakeholder and sustainability theories were identified as providing the lens for the study. Institutional theory (major theory underpinning study) provides that forces around them shape organisations to adopt greener initiatives. A multi-method qualitative research choice was made for the study.
After a comprehensive literature review, a preliminary framework of environmental management accounting practices to promote green gold mining in Zimbabwe was developed. The preliminary framework was enhanced by conducting personal interviews and later validated through a focus group. Findings revealed that coercive pressure was mostly applied by the environmental regulator and that gold mining activities negatively impacted the environment. In addition, gold mining companies failed to import green technology equipment due to excessive tax rates charged by the Zimbabwean Revenue Authority (ZIMRA). Key recommendations are that small gold mines should continually be monitored, and ZIMRA should reduce its tax rates to reduce the cost for gold mining organisations to import green technology. The study contributed to the body of knowledge and practice by developing an integrated framework for the Zimbabwean gold mining sector as a guide to greener gold mining and to theory (the integrated framework will work as a formal rule to be followed by entities). Similar work focusing on mining sectors like coal, platinum and chrome could be undertaken in Zimbabwe.Nanxa imboni yezokumbiwa kwegolide eZimbabwe inconywe ngeqhaza layo elihle ekukhuliseni umnotho, iphinde yagxekwa ngokulimaza imiphakathi yasendaweni ngokuxoshwa ngendluzula kanye nokufuduswa kwemiphakathi ngaphandle kokunikeza isinxephezelo esanele, ukungcoliswa kwamanzi nomoya, ukulahlekelwa amadlelo kanye nomhlaba wezolimo, ukwakhiwa kwemigodi engavikelekile, nokuxhashazwa kanye nokuqedwa kwemithombo yemvelo. Izincwadi zihlonze ukubalwa kwezindleko zokugeleza kwezinto (MFCA), izindleko zomjikelezo wokuphila (LCC) kanye nezindleko ezisekelwe kumsebenzi (ABC) njengezinqubo zokubala zokuphathwa kwemvelo ezibalulekile (EMAPs) zokuphatha imvelo. Ama-EMAP avame ukuxoxwa ngawo wodwa yingakho kunesidingo sokuwahlanganisa. Izinhlaka zamanje ziyehluleka ukuqondisa ukusimama ezinhlanganweni, ukuvula izingcingo zezindlela ezintsha ezihlanganisa ukusimama ezinqubeni zebhizinisi. Ucwaningo lugqugquzelwe ukuntuleka kwezifundo ngokubaluleka kwama-EMAP, okuphawulwe emazweni asathuthuka. Ngenxa yokwehluleka kwezinhlaka ezikhona ukubhekana nezinselele zezemvelo, izindlela ezingokoqobo namasu okudidiyela amabhizinisi, ukulinganisa kanye nokuxhumana ngezindaba zemvelo kusalokhu kuyinselele. Izinhlaka ezikhona zibonwe njengezintula izinga lemboni, ngaphandle kokwehluleka ukuchaza indlela yokufeza ukuhlanganiswa kokusimama.
Imibuzo yocwaningo nezinjongo zocwaningo zakhiwe kusukela esitatimendeni senkinga. Izindlela zokuqonda izinhlangano kanye nezinqubo zokuphatha, ababambiqhaza kanye nokusimama zihlonzwe njengezinikeza ithuluzi lomcwaningi lokubuka ucwaningo. Indlela yokuqonda izinhlangano kanye nezinqubo zokuphatha (Umbono omkhulu osekela ucwaningo) ihlinzeka ngokuthi amandla okubazungezile alolonge izinhlangano ukuthi zithole inqubo ephelele yokuphatha imvelo. Kwakhethwa ucwaningo lokuchaza lwezindlela eziningi kulolu cwaningo. Ngemva kokuhlolwa okupheleleyo kwezincwadi, kwasungulwa uhlaka lokuqala lwendlela yokuphathwa kwemvelo ukuze kuthuthukiswe ukumbiwa kwegolide eliluhlaza eZimbabwe. Uhlaka lokuqala lwathuthukiswa ngokwenza inhlolokhono yomuntu siqu futhi kamuva lwaqinisekiswa ngeqembu okugxilwe kulo. Okutholakele kuveze ukuthi ingcindezi ephoqayo yayisetshenziswa kakhulu umlawuli wezemvelo nokuthi imisebenzi yokumba igolide ibe nomthelela omubi kumvelo. Phezu kwalokho, izinkampani ezemba igolide zehlulekile ukuthenga kwamanye amazwe ubuchwepheshe bezemvelo ngenxa yokukhokhwa kwemithelo eyeqisayo ebizwe Yisiphathimandla Semali Engenayo yaseZimbabwe (ZIMRA). Iziphakamiso ezisemqoka ngezokuthi imigodi emincane yegolide kumele ihlale igadiwe, futhi iZIMRA kumele yehlise imithelo ukuze yehlise izindleko zezinhlangano ezemba igolide ukuthi zithenge kwamanye amazwe ubuchwepheshe bezemvelo.
Ucwaningo lufake isandla kumgwamanda wolwazi nokuzejwayeza ngokwenza uhlaka oludidiyelwe lwemboni yezezimayini zegolide zaseZimbabwe njengomhlahlandlela wokumbiwa kwegolide eliluhlaza kanye nombono (uhlaka oludidiyelwe luzosebenza njengomthetho osemthethweni okufanele ulandelwe yizinhlangano). Umsebenzi ofanayo ogxile emikhakheni yezimayini efana namalahle, iplatinum kanye nechrome ungenziwa eZimbabwe.Alhoewel die Zimbabwiese goudmynbedryf opgehemel is vir sy positiewe bydrae tot ekonomiese groei, het die bedryf ook onder skoot gekom vir sy skade aan plaaslike gemeenskappe deur die gedwonge uitsettings en hervestiging van gemeenskappe sonder voldoende vergoeding, water- en lugbesoedeling, verlies aan beweiding en landbougrond, die skep van onbeskermde skagte, en die uitbuiting en uitputting van natuurlike hulpbronne. Die literatuurstudie het wesenlike vloeikosteberekening (MFCA), lewensikluskosteberekening (LCC) en aktiwiteitsgebaseerde kosteberekening (ABC) as essensiële omgewingsbestuur rekeningkundige praktyke (EMAPs) geïdentifiseer om die omgewing te bestuur. Aangesien die neiging is om EMAPs in isolasie te gebruik, is daar ’n behoefte om hulle te integreer. Huidige raamwerke slaag nie daarin om volhoubaarheid in organisasies te bestuur nie, wat die geleentheid skep vir ’n oproep tot nuwe benaderings wat volhoubaarheid met besigheidsprosesse integreer. Die beweegrede vir die studie is die gebrek aan navorsing (wat in ontwikkelende lande bespeur is) oor die belangrikheid van EMAPs. As gevolg van die bestaande raamwerke se onvermoë om omgewingsuitdagings te hanteer, bly praktiese metodes en tegnieke om omgewingskwessies te integreer, meet, en kommunikeer steeds ’n uitdaging vir besighede. Afgesien dat hulle misluk het om ’n beskrywing te gee van hoe om die integrasie van volhoubaarheid te verwerf, is dit duidelik dat bestaande raamwerke nie op industriële skaal is nie. Die probleemstelling is gebruik om navorsingsvrae en navorsingsdoelwitte te ontwikkel. Institusionele, belanghebber- en volhoubaarheidsteorieë is geïdentifiseer as synde ’n lens vir die studie te verskaf. Volgens die institusionele teorie (hoofteorie wat die studie steun), is dit magte buite organisasies wat bepalend is in organisasies se aanneem van groener inisiatiewe. Die studie het multi-metode, kwalitatiewe navorsing gebruik.
Na ’n omvattende literatuuroorsig, is ’n voorlopige raamwerk vir omgewingsbestuur rekeningkundige praktyke vir die bevordering van groen goudmynwese in Zimbabwe ontwikkel. Hierdie voorlopige raamwerk is versterk deur persoonlike onderhoude wat gevoer is en is later deur ’n fokusgroep bekragtig. Die bevindinge het aan die lig gebring dat die omgewingsbeheerraad grotendeels dwang toegepas het en dat goudmynbedryfaktiwiteite die omgewing negatief affekteer. Daar is bykomend ook gevind dat maatskappye wat in die goudmynbedryf betrokke is, in gebreke gebly het om groentegnologie-toerusting in te voer as gevolg van die buitensporige belasting wat deur die Zimbabwean Revenue Authority (ZIMRA) gehef word. Die vernaamste aanbevelings is dat klein goudmyne deurlopend gemonitor moet word en dat ZIMRA sy belastingkoerse moet verlaag om goudmynorganisies se koste vir die invoer van groentegnologie te verminder. Die studie het tot die breë kennisbasis en praktyk bygedra deur ’n geïntegreerde raamwerk vir die Zimbabwiese goudmynsektor as riglyn tot groener goudmynwese, sowel as teorie te ontwikkel (die geïntegreerde raamwerk sal as formele reël dien wat deur entiteite gevolg moet word). Soortgelyke ondersoeke wat op ander mynsektore soos steenkool, platinum en chroom fokus, kan in Zimbabwe onderneem word.D. Phil. (Accounting Sciences (Management Accounting))Management Accountin
The influence of information and communication technology on the organisational commitment of mobile knowledge workers
No full textText in English with abstracts and keywords in English, Afrikaans and SesothoThe corporate landscape induces numerous challenges regarding sustained productivity, creating a committed workforce, and addressing the increasing level of user dependence on technology. As employee dependence on technology increases, it becomes vital to not only understand the concept of employee commitment but also the impact and influence that technology has on such commitment. Mobile knowledge workers are highly dependent on technology to
complete their tasks. The mobile landscape poses various challenges to a mobile knowledge worker; these are, amongst others, connectivity issues, alienation and isolation from their colleagues, reduced opportunities for relationship building, and a degraded corporate identity.
Whilst implementing technology to address the various challenges brought about by the mobile work landscape is a noble goal, it is important that the technology earmarked for introduction to the workers is appropriate for the end-users of the technology and the tasks the workers need to complete. By exploring the research
questions presented in this study, this study investigates the influence that technology has on the organisational commitment of mobile knowledge workers and how technology can be leveraged to influence their organisational commitment. This study found that research on the organisational commitment of specifically mobile knowledge workers is lacking in the current knowledge base.
The study, therefore, contributes to the current knowledge base by starting to address the gap in the current knowledge base pertaining to the organisational commitment of mobile workers. The deliverable is a novel Mobile Worker Commitment framework that establishes which aspects of the organisational commitment of mobile knowledge workers are influenced by technology.
Organisations can use the Mobile Worker Commitment framework when attempting to understand organisational commitment from mobile knowledge workers' viewpoint and as a guide when considering where to spend effort and/or resources, should they wish to influence the organisational commitment of mobile knowledge workers.Die korporatiewe landskap bring verskeie uitdagings vir volgehoue produktiwiteit, 'n toegewyde arbeidsmag, en die toenemende afhanklikheid van tegnologie mee.
Soos wat werknemers se afhanklikheid van tegnologie verhoog, word dit belangrik om nie net die konsep van werknemertoewyding te verstaan nie, maar ook die impak en invloed van tegnologie op werknemertoewyding. Mobiele kenniswerkers is hoogs afhanklik van tegnologie om hulle daaglikse take te voltooi. Die landskap
het verskeie uitdagings vir mobiele kenniswerkers, onder andere, uitdagings met internetverbindings, isolasie van kollegas, kleiner kanse om verhoudings met kollegas te bou, en 'n laer korporatiewe identiteit.
Terwyl die implementasie van tegnologie om die bogenoemde uitdagings te bekamp 'n edele doelwit is, is dit belangrik dat die tegnologie wat geoormerk word, gepas is vir die tegnologiegebruikers. Die navorsingsvrae in hierdie studie ondersoek die impak van tegnologie op die korporatiewe toewyding van mobiele
kenniswerkers en hoe tegnologie deur 'n maatskappy gebruik kan word om korporatiewe toewyding te beïnvloed. Hierdie studie het bevind dat navorsing oor die toewyding van spesifiek mobiele kenniswerkers in die huidige kennisbasis ontbreek.
Die studie dra dus tot die kennisbasis by deur die gaping in die toewyding van mobiele kenniswerkers te ondersoek. Die studie lê 'n nuwe raamwerk voor, naamlik die "Mobiele erkertoewydingsraamwerk", wat die aspekte van die toewyding van mobiele kennis werkers identifiseer wat tegnologie kan beïnvloed.
Maatskappye kan die raamwerk gebruik om dieper kennis rakende korporatiewe toewyding vanuit mobiele kenniswerkers se oogpunt te bekom. Die raamwerk kan ook as 'n gids dien vir maatskappye om vas te stel hoe om hul tyd en hulpbronne te spandeer indien hulle die korporatiewe toewyding van mobiele kenniswerkers wil beïnvloed.Boemo ba kgwebo bo baka diphephetso tse ngata mabapi le tlhahiso e tsitsitseng, ho bopa basebetsi ba ikemiseditseng, le ho sebetsana le boemo bo ntseng bo eketseha ba tshebediso ya mosebedisi theknolojing.

Towards specification formalisms for data warehouse systems design
No full textText in English with abstracts and keywords in English, Afrikaans and SetswanaSeveral studies have been conducted on formal methods; however, few of these studies
have used formal methods in the data warehousing area, specifically system
development. Many reasons may be linked to that, such as that few experts know how to
use them. Formal methods have been used in software development using mathematical
notations. Despite the advantages of using formal methods in software development,
their application in the data warehousing area has been restricted when compared with
the use of informal (natural language) and semi-formal notations.
This research aims to determine the extent to which formal methods may mitigate failures
that mostly occur in the development of data warehouse systems. As part of this research,
an enhanced framework was proposed to facilitate the usage of formal methods in the
development of such systems. The enhanced framework focuses mainly on the
requirements definition, the Unified Modelling Language (UML) constructs, the Star
model and formal specification. A medium-sized case study of a data mart was
considered to validate the enhanced framework. This dissertation also discusses the
object-orientation paradigm and UML notations.
The requirements specification of a data warehouse system is presented in natural
language and formal notation to show how a formal specification may be drifted from
natural language to UML structures and thereafter to the Z specification using an
established strategy as a guideline to construct a Z specificationAlhoewel verskeie studies oor formele metodes gedoen is, het min hiervan formele
metodes in die databergingarea, spesifiek stelselontwerp, gebruik. Dit kan aan baie redes
toegeskryf word, soos dat min kundiges weet hoe om dit te gebruik. Formele metodes is
in sagtewareontwikkeling gebruik wat wiskundige notasies gebruik. Ten spyte van die
voordele van formele metodes in sagtewareontwikkeling, is die toepassing daarvan in
die databergingarea beperk wanneer dit met die gebruik van informele (natuurlike taal)
en semiformele notasies vergelyk word.
Hierdie navorsing beoog om te bepaal tot watter mate formele metodes foute kan
uitskakel wat hoofsaaklik in die ontwikkeling van databeringstelsels voorkom. As deel
van hierdie navorsing is 'n beter raamwerk voorgestel om die gebruik van formele
metodes in die ontwikkeling van sulke stelsels te fasiliteer. Die beter raamwerk fokus
hoofsaaklik op die definisie van vereistes, die Unified Modelling Language (UML) -
konstukte, die Star-model en formele spesifikasies. Die mediumgrootte gevallestudie van
'n datamark is oorweeg om die beter raamwerk geldig te verklaar. Hierdie verhandeling
bespreek ook die voorwerpgeoriënteerde paradigma en die UML-notasies.
Die vereiste spesifikasie van 'n databergingstelsel word in natuurlike taal en formele
notasie voorgehou om aan te dui hoe 'n formele spesifikasie van natuurlik taal na UML strukture kan verskuif en daarna na die Z-spesifiekasie deur 'n gevestigde strategie as 'n
riglyn te gebruik om 'n Z-spesifikasie te konstrueer.Go nnile le dithutopatlisiso di le mmalwa ka mekgwa e e fomale, fela ga se

A framework for the adoption of digital solutions in South African state-owned enterprises (SOEs)
No full textAbstract in English, Sepedi and AfrikaansLike other countries, South Africa has several enterprises wholly or partially owned by the state, known as state-owned enterprises (SOEs). The South African Public Finance Management Act of 1999 (PFMA) indicates that there are nine Schedule 1 (constitutional) entities, 21 Schedule 2 (major public) entities, 155 Schedule 3 (other national public entities) entities, and 72 provincial entities. Digitalisation, especially through Fourth Industrial Revolution (4IR) technologies, promises numerous opportunities for SOEs, but it is uncertain to what extent they are positioned to embrace these opportunities to address their challenges. Following an inductive research approach and a qualitative research choice, scholarly literature on SOEs was researched, and sets of qualitative propositions were formulated. These propositions and existing technology adoption frameworks, notably the Technology-Organisation-Environment (TOE) framework, were used to define a conceptual digitalisation framework for 4IR adoption by SA SOEs. Executives from various SOEs were interviewed to enhance and validate the framework and explore the readiness of SOE leadership to accept digitalisation. The validation of the conceptual framework focused on six components: governance and leadership; digitalisation strategies; 4IR technologies; skills and training; the environment; and collaboration. Governance and risk management were noted as interrelated components. The SOE executives welcomed the framework, highlighting several challenges in their SOEs: change management; digitally savvy leadership; digital skills; regulation or policies; funding; and general support and willingness. The importance of adopting 4IR components, such as Blockchain, advanced analytics, artificial intelligence, the internet of things, robotic process automation, drones, and the like, was indicated as a pipe dream by most SOE executives, although some were already exploring certain 4IR initiatives. Also, the COVID-19 pandemic was found to be a wake-up call for SOE leadership, forcing them to think more about digitalisation. Executive collaboration was recommended at all levels regarding strategies, funding (collective buying), skills sharing, and research in 4IR, among other things. The interview findings prompted the definition of a set of additional propositions, which were used to enhance the framework. Future work in this area is noted as developing an SOE digitalisation strategy and developing toolsets to assist SOEs in 4IR digital adoption.Go swana le ka dinageng tse dingwe, Afrika Borwa e na le dikgwebo tse mmalwa tseo di lego tsa mmuso ka botlalo goba ka seripa, tseo di tsebjago bjalo ka dikgwebo tsa mmuso (di-SOE).

Kragtens die Suid-Afrikaanse Wet op Openbare Finansiele Bestuur van 1999 is daar nege Skedule 1- (konstitusionele) entiteite, 21 Skedule 2- (hoof- publieke) entiteite, 155 Skedule 3- (ander nasionale publieke) entiteite en 72 provinsiale entiteite. Digitalisering, veral deur tegnologiee van die Vierde Industriele Revolusie, verseker verskeie geleenthede vir SBO’s, maar dit is onseker tot watter mate hulle geposisioneer is om hierdie geleenthede aan te gryp om hulle uitdagings aan te pak. Daar is ’n induktiewe navorsingsbenadering en ’n kwalitatiewe navorsingskeuse gevolg, en wetenskaplike literatuur oor SBO’s is nagevors, en stelle kwalitatiewe voorstelle is geformuleer. Hierdie voorstelle en bestaande raamwerke vir die aanname van tegnologie, veral die Tegnologie-Organisasie-Omgewing-raamwerk (Technology-Organisation-Environment (TOE) framework) is gebruik om ’n konseptuele digitaliseringsraamwerk te definieer vir Vierde Industriele Revolusie-aanname deur Suid-Afrikaanse SBO’s. Daar is onderhoude gevoer met bestuursamptenare van verskeie SBO’s om die raamwerk te bevorder en geldig te verklaar, en om die gereedheid van SBO-leierskap te verken om digitalisering te aanvaar. Die geldigverklaring van die konseptuele raamwerk het op ses komponente gefokus: regering en leierskap; digitaliseringstrategiee; Vierde Industriele Revolusie-tegnologiee; opleiding en vaardighede; die omgewing; en samewerking. Regering en risikobestuur is aangeteken as onderling verbonde komponente. Die SBO-bestuursbeamptes het die raamwerk verwelkom, en verskeie uitdagings in hulle SBO’s beklemtoon: hantering van verandering; digitaal kundige leierskap; digitale vaardighede; regulering van beleide; befondsing; en algemene ondersteuning en gewilligheid. Die belangrikheid om Vierde Industriele Revolusie-komponente aan te neem, soos blokketting (blockchain), gevorderde ontleedkunde, kunsmatige intelligensie, die Internet van Dinge (Internet of Things), robotagtige proses-outomatisering, hommeltuie (drones) en so meer, is aangedui as ’n dagdroom (pipe dream) vir die meeste SBO-bestuursbeamptes, hoewel sommige bestuursbeamptes reeds sekere Vierde Industriele Revolusie-inisiatiewe verken. Die COVID-19-pandemie was ook ’n wekroep vir SBO-leierskap, en het hulle gedwing om meer te dink oor digitalisering. Uitvoerende samewerking is aanbeveel op alle vlakke wat betref strategiee, befondsing (gesamentlike aankope), die deel van vaardighede, en navorsing oor die Vierde Industriele Revolusie, onder andere. Die onderhoud-bevindings het gelei tot die definisie van ’n stel bykomende voorstelle, wat gebruik is om die raamwerk te bevorder. Daar is aangeteken dat toekomstige werk op hierdie gebied die ontwikkeling van ’n SBO-digitaliseringstrategie en ontwikkeling van hulpmiddels om SBO’s te help met digitale aanname in die Vierde Industriele Revolusie insluit.D.B.L.

Knowledge management systems : an adoption framework for small and medium enterprises (SMEs)
No full textTechnology is becoming increasingly affordable and accessible through advances in innovation. At the same time, valuable organisational resources are moving from tangible (e.g., steel) to intangible resources (e.g., knowledge). For this reason, knowledge is viewed by many scholars as a sustainable competitive advantage. To compete successfully in the knowledge economy, organisational knowledge should be appropriately managed through management practices encompassing the creation, storage, retrieval, transfer and application of knowledge using IT systems. The combination of hardware and software to drive knowledge management (KM) is known as a knowledge management system (KMS). The literature has consistently acknowledged the high failure rates of technology adoption in organisations. It can have devastating consequences for small and medium enterprises (SMEs) as they have fewer resources to recover from KMS adoption failure. Equally important is the fact that SMEs contribute substantially to the gross domestic product and employment of national economies worldwide. The same is true for South African SMEs.
Given the picture of KM in the SME context, it is important to investigate potential factors that can lead to improved KMS adoption in SMEs. As scholarly literature on KMS adoption in SMEs is limited, this study could contribute uniquely to the body of knowledge focused on these factors. Within the Technology-Organisation-Environment (TOE) framework, Diffusion of Innovation (DOI) and critical success factors (CSF), the study constructed a framework for KMS adoption in SMEs. After constructing a preliminary conceptual framework from the literature, data was collected using a two-phase approach. In phase one, four mini focus groups comprising four SMEs each were interviewed. The thematic analysis revealed eight themes that expanded the existing framework. The purpose of phase two was to validate the framework developed in phase one through face-to-face or online discussions with six SME subject matter experts. Phase two identified five themes that further confirmed and strengthened the framework. The study contributed on a theoretical, empirical and practical level. Having identified several key factors for KMS adoption, the framework aims to improve the use of KMS in SMEs by employees and, as a result, SME performance and sustainability. Future research could condense or identify additional factors to test the framework developed in the study. In addition, the framework could be tested on specific industries or with larger sample sizes.D.B. L.Graduate School of Business Leadershi
A nanotechnology strategic key research areas foresight model for improved innovation and technology transfer
No full textAbstracts in English, Afrikaans and ZuluNanotechnology revolutionised industrialisation and economic development and is predicted to drive the next Schumpeterian wave of economic growth. Most countries are strategically positioning themselves to benefit from nanotechnology, being a general-purpose technology. Hence, to ensure prudent use of limited resources, countries must select and focus on key strategic nanotechnology research areas that have the potential to generate competitiveness and return on investment. However, no model currently exists on critical success factors for nanotechnology innovation management. Also, there is a lack of effective nanotechnology-specific foresight models. Furthermore, although nanotechnology foresight relates to the Multi-criteria Decision Making (MCDM) analysis, the use of MCDM methods in a foresight context has not been thoroughly explored yet.
This research developed the Nanotechnology Innovation Diamond, a model for successful nanoscience research and development. The model was validated using confirmatory factor analysis (CFA) from a survey of 167 nanotechnology experts from South Africa. The results indicated that, at a 95% confidence level, the model satisfied the minimum CFA model fit requirements. The research further developed a nanotechnology-specific foresight model that integrates the Nanotechnology Innovation Diamond, technology mining, scientometrics, and the Analytical Hierarchical Process Multi-criteria Decision Making (AHP-MCDM) model.
The AHP-MCDM foresight model was empirically tested in South Africa. The results showed that South Africa’s nanotechnology publications grew exponentially from 68 papers in 2000 to 1 672 in 2019, representing an increase of 2 459%. Compared to the other BRICS countries, namely, Brazil, Russia, India, and China, South Africa has the lowest nanotechnology productivity, scoring an activity index of 0.68. Universities are the most prominent publishers on nanotechnology, while the private sector has produced few publications. Only 48 patents were identified compared to 11 265 publications, and a meagre 3.5% of papers were found to report on nano-enabled products. This lack of reporting on nano-enabled products can negatively impact the commercialisation of nanotechnology. The top collaborating countries, top researchers, top institutions, and nanotechnology economic hubs are reported in this study. The key strategic research areas identified for South Africa include nanomaterials, nano-photoluminescence and optics, nanomedicine, nanocatalysis, nanoelectronics, nanobiotechnology, and energy. The results were benchmarked using an expert-survey foresight method, which gave 70% similar priority fields of research. The research contributes to the discourse on nanotechnology innovation management, technology-specific foresight methods, nanotechnology-specific foresight methods, and the utilisation of quantitative tools in foresight.Nanotegnologie het ’n omwenteling in industrialisering en ekonomiese ontwikkeling teweeggebring en daar word voorspel dat dit die volgende Schumpeterse golf van ekonomiese groei sal aandryf. Die meeste lande is besig om hulself strategies te posisioneer om uit nanotegnologie voordeel te trek, aangesien dit ’n meerdoelige tegnologie is. Om dus verstandige gebruik van beperkte hulpbronne te verseker, moet lande strategiese sleutelnavorsingsareas in nanotegnologie wat die potensiaal het om mededingendheid en opbrengs op belegging te genereer, kies en daarop fokus. Daar bestaan egter nie op die oomblik ’n model ten opsigte van kritiese suksesfaktore vir nanotegnologie-innovering-bestuur nie. Boonop is daar ’n tekort aan doeltreffende nanotegnologie-spesifieke toekomsbeplanningsmodelle. Hoewel toekomsbeplanning vir nanotegnologie verband hou met die Multi-criteria Decision Making (MCDM)-ontleding, is die gebruik van MCDM-metodes in ’n toekomsbeplanning-konteks nog nie behoorlik ondersoek nie.
In hierdie navorsing is die Nanotechnology Innovation Diamond ontwikkel – ’n model vir suksesvolle nanowetenskap-navorsing en -ontwikkeling. Om die geldigheid van die model te bepaal, is bevestigende faktorontleding (CFA) van ’n opname onder 167 nanotegnologiekundiges van Suid-Afrika gebruik. Die resultate het aangetoon dat die model aan die minimum CFA-modelgeskiktheidvereistes voldoen het, met ’n 95%-vertroubaarheidsvlak. Verder het die navorsing ’n nanotegnologie-spesifieke toekomsbeplanningsmodel ontwikkel wat die Nanotechnology Innovation Diamond, tegnologie-ontginning, scientometrie, en die Analytical Hierarchical Process Multi-criteria Decision Making (AHP-MCDM) -model integreer.
Die AHP-MCDM-toekomsbeplanningsmodel is empiries getoets in Suid-Afrika. Die resultate het getoon dat Suid-Afrika se nanotegnologie-publikasies eksponensieel gegroei het van 68 artikels in 2000 tot 1 672 in 2019 – dit verteenwoordig ’n toename van 2 459%. In vergelyking met die ander BRICS-lande, naamlik Brasilië, Rusland, Indië, en China, het Suid-Afrika die laagste syfer ten opsigte van nanotegnologie- produktiwiteit, met ’n bedrywigheidsindekssyfer van 0.68. Universiteite is die mees prominente uitgewers wanneer dit by nanotegnologie kom, terwyl die private sektor ’n paar publikasies opgelewer het. Slegs 48 patente is geïdentifiseer in vergelyking met 11 265 publikasies, en daar is bevind dat ’n skamele 3.5% van die artikels oor nano-geaktiveerde produkte verslag doen. Hierdie gebrek aan verslagdoening oor nano-geaktiveerde produkte kan ’n negatiewe uitwerking op die kommersialisering van nanotegnologie hê. In hierdie studie word verslag gedoen oor die lande, navorsers, instansies, en nanotegnologie- ekonomiese middelpunte wat die voortou neem. Die strategiese sleutelnavorsingsareas wat vir Suid-Afrika geïdentifiseer is, sluit nanomateriale, nano-fotoluminessensie en optika, nanomedisyne, nanokatalise, nano-elektronika, nanobiotegnologie, en energie in. Die resultate is genormeer met behulp van ’n kundige-opname-toekomsbeplanningsmetode, wat 70% soortgelyke-prioriteit-navorsingsvelde gelewer het. Die navorsing dra by tot die gesprekvoering oor nanotegnologie-innoveringsbestuur, tegnologie-spesifieke toekoms beplannings metodes, nanotegnologiespesifieke toekomsbeplanningsmetodes, en die benutting van kwantitatiewe middele in toekomsbeplanning.Igatsha lobuchwepheshe elibhekene nobukhulu nokubekezelelana liguqule ukuthuthukiswa kwezimboni nokuthuthukiswa komnotho futhi kubikezelwa ukuthi liza ngomkhulu umfutho olandelayo le-Schumpeterian lokukhula komnotho.

Estimating ankle muscle parameters. Developing a tendon dynamics included neuromechanical muscle model and expanding the measurement protocols to improve ankle muscle parameter estimation accuracy
No full textCurrent neuromechanical muscle models are unable to accurately estimate both passive and active muscle components. In this study it is investigated to increase the neuromechanical parameter estimations by using an input-rich measurement protocol and by expanding the ankle muscle model with tendon dynamics. New measurement protocols are developed using a structured method through model simulations. Enriching the measurement protocol was found to lead to good modelling fits (high VAF, low SEM). Expanding the muscle model with tendon dynamics was found to lead to similar results as compared to the muscle model without tendon dynamics.BioMechatronicsBioMechanical EngineeringMechanical, Maritime and Materials Engineerin
