Full textAbstract:
This thesis employs perspectives inspired by General Systems Theory to address issues in philosophy, including moral philosophy and philosophy of mind. I present an overview of a range of ideas from the study of physical systems that may be used to provide a firm physicalist foundation to explorations of some common questions in philosophy. I divide these topics into three categories: the Physical Category, the Relevance Category and the Signal Elements Category. I interpret concepts from General Systems Theory, including information and entropy, in a way that I believe facilitates their incorporation into philosophical discussion. I also explain various points arising from General Systems Theory, such as order and disorder, stability, complexity, and self-organisation, and show how ideas from these areas can be applied to certain philosophical problems. I explain relevance in terms of stability, in order to link these scientific perspectives to questions in moral philosophy. I suggest a possible physical foundation for a theory of morality, which takes the form of a variety of Utilitarianism, intended to balance the competing needs of open systems to manage entropy. Such a theory of morality must be capable of dealing with limitations arising from the physicality of information; I propose game theory as a solution to this problem. This thesis also covers issues connected to the above points regarding the nature of consciousness and communication. In particular, I examine the role of linguistic associations in consciousness; and some related features of language and other non-linear representational schemes.

De, Coning Cedric Hattingh. "Complexity, peacebuilding and coherence : implications of complexity for the peacebuilding coherence dilemma." Thesis, Stellenbosch : Stellenbosch University, 2012. http://hdl.handle.net/10019.1/71891.
Full textAbstract:
Thesis (PhD)--Stellenbosch University, 2012.ENGLISH ABSTRACT: This dissertation explores the utility of using Complexity studies to improve our understanding of peacebuilding and the coherence dilemma, which is regarded as one of the most significant problems facing peacebuilding interventions. Peacebuilding is said to be complex, and this study investigates what this implies, and asks whether Complexity could be of use in improving our understanding of the assumed causal link between coherence, effectiveness and sustainability. Peacebuilding refers to all actions undertaken by the international community and local actors to consolidate the peace – to prevent a (re)lapse into violent conflict – in a given conflict-prone system. The nexus between development, governance, politics and security has become a central focus of the international effort to manage transitions, and peacebuilding is increasingly seen as the collective framework within which these diverse dimensions of conflict management can be brought together in one common framework. The coherence dilemma refers to the persistent gap between policy-level assumptions about the value and causal role of coherence in the effectiveness of peacebuilding and empirical evidence to the contrary from peacebuilding practice. The dissertation argues that the peacebuilding process is challenged by enduring and deep-rooted tensions and contradictions, and that there are thus inherent limits and constraints regarding the degree to which coherence can be achieved in any particular peacebuilding context. On the basis of the application of the general characteristics of Complexity to peacebuilding, the following three recommendations reflect the core findings of the study: (1) Peacebuilders need to concede that they cannot, from the outside, definitively analyse complex conflicts and design ‘solutions’ on behalf of a local society. Instead, they should facilitate inductive processes that assist knowledge to emerge from the local context, and such knowledge needs to be understood as provisional and subject to a continuous process of refinement and adaptation. (2) Peacebuilders have to recognise that self-sustainable peace is directly linked to, and influenced by, the extent to which a society has the capacity, and space, to selforganise. For peace consolidation to be self-sustainable, it has to be the result of a home-grown, bottom-up and context-specific process. (3) Peacebuilders need to acknowledge that they cannot defend the choices they make on the basis of pre-determined models or lessons learned elsewhere. The ethical implications of their choices have to be considered in the local context, and the effects of their interventions - intended and unintended - need to be continuously assessed against the lived-experience of the societies they are assisting. Peacebuilding should be guided by the principle that those who will have to live with the consequences should have the agency to make decisions about their own future. The art of peacebuilding lies in pursuing the appropriate balance between international support and home-grown solutions. The dissertation argues that the international community has, to date, failed to find this balance. As a result, peacebuilding has often contributed to the very societal weaknesses and fragilities that it was meant to resolve. On the basis of these insights, the dissertation concludes with a call for a significant re-balancing of the relationship between international influence and local agency, where the role of the external peacebuilder is limited to assisting, facilitating and stimulating the capacity of the local society to self-organise. The dissertation thus argues for reframing peacebuilding as something that must be essentially local.
AFRIKAANSE OPSOMMING: Hierdie proefskrif ondersoek die toepaslikheid van Kompleksiteitstudies om ons begrip van vredesbou en die dilemma van koherensie te verbeter, wat as een van die gewigtigste probleme vir die toetrede tot vredesbou beskou kan word. Vredesbou word as kompleks beskou en die implikasies van hierdie siening word in hierdie proefskrif ondersoek. Dienooreenkomstig word die vraag na die nut van Kompleksiteitstudies vir die verbetering van ons begrip van die veronderstelde kousale verband tussen koherensie, doeltreffendheid en volhoubaarheid aangespreek. Vredesbou verwys na alle handelinge wat deur die internasionale gemeenskap en plaaslike belanghebbendes onderneem word om vrede binne ʼn gegewe sisteem, wat neig na konflik, te konsolideer om sodoende ’n (her)verval in gewelddadige konflik te voorkom. Die aanknopingspunt tussen ontwikkeling, staatsbestuur, staatkunde en sekuriteit is tans die sentrale fokus van die internasionale poging om sodanige oorgange te beheer, en vredesbou word toenemend as ’n kollektiewe raamwerk beskou, waarbinne hierdie onderskeie dimensies van konflikbestuur in een gemeenskaplike raamwerk saamgebring kan word. Die koherensiedilemma verwys na die voortdurende gaping tussen beleidsvlakaannames ten opsigte van die waarde en kousale rol van koherensie vir die doeltreffendheid van vredesboupogings en empiriese data vanuit die vredesboupraktyk wat hierdie aanvaarde kousale verband weerspreek. Die proefskrif toon dat vredesboupogings uitgedaag word deur voortdurende en diepgewortelde spanninge en teenstrydighede, en dat daar dus inherente beperkings en stremmings is ten opsigte van die mate waartoe koherensie binne enige spesifieke vredesboukonteks moontlik is. Op grond van die toepassing van die algemene kenmerke van Kompleksiteitstudies op die vredesbouproses, weerspieël die volgende drie aanbevelings die kernbevindings van die studie: (1) Vredesbouers moet toegee dat hulle nie daartoe in staat is om komplekse konflikte van buite af bepalend te analiseer en ‘oplossings’ namens ’n plaaslike gemeenskap te ontwerp nie. Hulle behoort eerder induktiewe prosesse te fasiliteer om ondersteuning te bied sodat kennis uit die plaaslike konteks na vore kom, en sodanige kennis moet as voorlopig en onderhewig aan ’n voortdurende proses tot verfyning en aanpassing, verstaan word. (2) Vredesbouers moet besef dat die selfvolhoubaarheid van vrede direk verband hou met, en beïnvloed word deur, die mate waartoe ’n gemeenskap oor die vermoë tot en ruimte vir selforganisering beskik. Vir vredeskonsolidering om selfvolhoubaar te wees, moet die proses wat daartoe aanleiding gee inheems, van ‘onder-na-bo’ en konteks-spesifiek wees. (3) Vredesbouers moet aanvaar dat hulle nie die besluite wat hulle neem op grond van voorafbestaande modelle of lesse wat elders geleer is kan regverdig nie. Die etiese implikasies van hulle besluite moet in terme van die plaaslike konteks beoordeel word, en die effekte van hulle ingrepe – bepland en onbepland – moet voortdurend opgeweeg word teen die daaglikse ervaring van die samelewings wat bygestaan word. Vredesbehoupogings behoort gelei te word deur die beginsel dat diegene wat met die gevolge van die proses sal moet saamleef, die agentskap behoort te hê om besluite oor hulle eie toekoms te neem. Die kuns van vredesbou lê in die vasstel van ’n toepaslike balans tussen internasionale ondersteuning en inheemse oplossings. Die proefskrif se argument is dat die internasionale gemeenskap tot dusver daarin gefaal het om hierdie balans te vind. As gevolg hiervan het pogings tot vredesbou dikwels bygedra tot die presiese swakhede en broosheid in die gemeenskap wat dit veronderstel was om aan te spreek. Op grond van hierdie insigte sluit die proefskrif af met ’n beroep tot ’n betekenisvolle herbalansering van die verhouding tussen internasionale invloed en plaaslike agentskap, waarin die rol van die eksterne vredesbouer beperk moet word tot die ondersteuning, fasilitering en stimulering van die plaaslike gemeenskap se vermoë tot selforganisering. Die proefskrif bepleit dus dat vredesbou herontwerp word binne ’n essensieel plaaslike raamwerk.

Full textAbstract:
Thesis (MPhil (Information Science))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: This thesis investigates investment theory in the light of complexity theory. These insights from diverse fields contain powerful images, metaphors and ways of thinking that allows one to seek new ways of comprehending the nature of the economy and therefore the nature of investment and the related issues of uncertainty and decision making. Complexity theory views the economy as being a dynamic, continuously adaptive, nonlinear system. This is in contrast to traditional or classical economic theory that views the economy as being a simple, linear, equilibrium deterministic system. This thesis is a conceptual study exploring the implications of a complexity worldview for investment decisions by looking at the nature and characteristics of complexity and then overlaying it on the characteristics of the economy. It is argued that complexity is caused by three elements: the structure of the system, human behaviour and exogenous factors. Thereafter follows an analysis of how investment decisions are made in the light of complexity by illustrating the investment models of two very successful, yet different investors: Warren Buffet and George Soros. Buffet’s model hinges on value. He realises that emergent phenomenon driven by irrational behaviour of investors leads to intrinsic values of shares to differ widely from perceived value. When quoted or perceived values are low than it is advisable to purchase as you have a margin of safety. Over the long term the market recognises the real value of the share. He tries to ignore the vagaries of the market and to focus on fundamentals. His list of fundamentals include; the franchise value of the company, quality of management and industry dynamics. George Soros in contrast utilises emergence patterns to locate potential investments. His model is that systems are flawed, human thinking and decision making is flawed and the interaction of the two lead to perturbations and oscillations. He focuses in trying to understand the flaw in systems and in human behaviour and to find some kind of pattern that he could utilise to make a profit. It is shown that both investment models can be understood from a complexity perspective and that these two investors built aspects from complexity into their decision models.
AFRIKAANSE OPSOMMING: Die tesis ondersoek investeringsteorie in die lig van kompleksiteitsteorie. Met die hulp van metafore en insigte vanuit kompleksiteitsdenke word gesoek na nuwe maniere om die aard van die mark en investering verwante aspekte van onsekerheid en besluitneming te verstaan. Die kompleksiteitsperspektief sien die ekonomie as’n dinamiese en aanpassende nie-lineêre sisteem. Dit word gedoen deur die implikasies wat kompleksiteit vir investeringsbesluite inhou konseptueel te ondersoek. Die aard en eienskappe van komplekse sisteme word verduidelik en dan op die ekonomie toegepas. Daar word geargumenteer dat kompleksiteit deur drie elemente veroorsaak word: die struktuur van die sisteem, menslike gedrag en eksogene faktore. Daarna word die praktyk van investeringsbesluite geanaliseer in terme van kompleksiteit duer investeringsmodelle van twee suksesvolle, maar uiteenlopende, investeerders te ondersoek, naamlik Warren Buffet en George Soros. Buffet se model draai rondom waarde. Hy sien die irrasionele gedrag van investeerders as ‘n ontvouende fenomeen wat lei tot ‘n gaping tussen intrinsieke en verwagte waarde. Sy investering word gebaseer op die aanname dat oor die langer termyn die mark die intrinsieke waarde herken. Hy ignoreer dus korttermyn skommelinge in die verwagte waarde en fokus op die fundamentele, waaronder die maanwaarde van die besigheid, die kwaliteit van die bestuur, en industrie-dinamika tel. Soros se model daarenteen gebruik ontvouende patrone en potensiële investeringsgeleenthede te ontbloot. Sy model is dat sisteme inherente teenstrydighede het as ook menslike gedrag en besluitneming. Dit lei tot ossilasies en versteurings. Sy fokus is gerig daarop om hierdie versteurings in die sisteem tot voordeel aan te wend. Daar word getoon hoedat beide investeringsmodelle vanuit ‘n kompleksiteitsperspektief verstaan kan word en dat die twee investeerders sulke aspekte in hulle investeringsbesluite inbou.

Full textAbstract:
Experimental aesthetics research has been conducted since the nineteenth century. Interestingly, however, few studies have examined the perceived beauty of naturally shaped objects. In the current experiment, 204 participants were presented with a set of ten snowflake silhouettes that varied in complexity (perimeter relative to area); they were similarly presented with ten randomly-shaped, computer-generated, solid objects that also varied in complexity. For each stimulus set, the participants selected the single snowflake or object that was the most beautiful (Fechner’s method of choice). The results for the solid objects replicated the findings of earlier research: the most and least complex objects were chosen as the most beautiful. Moderately complex objects were rarely selected. The results for the snowflakes were different. For these visual stimuli, the least complex snowflakes were almost never chosen; only the complex snowflakes were perceived to be most beautiful, with the aesthetic preference increasing with increases in complexity.

Full textAbstract:
It has often been said that the problem of creating timetables for scheduling university courses is hard, even as hard as solving an NP-Complete problem. There are many papers in the literature that make this assertion but rarely are precise problem definitions provided and no papers were found which offered proofs that the university course scheduling problem being discussed is NP-Complete.
This thesis defines a scheduling problem that has realistic constraints. It schedules professors to sections of courses they are willing to teach at times when they are available without overloading them. Both decision and optimization versions are precisely defined. An algorithm is then provided which solves the optimization problem in polynomial time. From this it is concluded that the decision problem is unlikely to be NP-Complete because indeed it is in P.
A second more complex timetable design problem, that additionally seeks to assign appropriate rooms in which the professors can teach the courses, is then introduced. Here too both decision and optimization versions are defined. The second major contribution of this thesis is to prove that this decision problem is NP-Complete and hence the corresponding optimization problem is NP-Hard.

Human, Oliver. "Potential economies : complexity, novelty and the event." Thesis, Stellenbosch : Stellenbosch University, 2011. http://hdl.handle.net/10019.1/18041.
Full textAbstract:
Thesis (PhD)--Stellenbosch University, 2011.ENGLISH ABSTRACT: The primary concern of this dissertation will be to understand under what conditions novelty arises within a system. In classical philosophy, the notion of novelty is usually said to arise out of an event. However, the notion of an event often carries with it metaphysical and conservative implications. Therefore, part of the concern of this dissertation is to begin to develop an approach to novelty which is not dependent upon the event. This approach is developed through the insights offered by Critical Complexity and post‐structuralist philosophy. In social science the model of the frame has dominated how to think about the limitations to the context specific nature of knowledge. Instead of the analogy of a frame, this dissertation argues that it is better to adopt the notion of an ‘economy’. This is due to the fact that the notion of an economy allows social scientists to better theorize the relationships which constitute the models they create. The argument for an economy is made by exploring the connections between the work of Jacques Derrida, the complexity theorist Edgar Morin and Georges Bataille. However, when using the notion of an economy, one must always take the excess of this economy into consideration. This excess always feeds back to disrupt the economy from which it is excluded. Using terms developed in complexity theory, this dissertation illustrates how a system adapts to the environment by using this excess. Due to this there can never be a comprehensively modelled complex system because there are always facets of this system which remain hidden to the observer. The work of Alain Badiou, whose central concern is the notion of novelty arising out of an event, is introduced. The implications of depending on the event for novelty to arise are drawn out by discussing the affinities between the work of Derrida and Badiou. In this regard, Derrida’s use of the term ‘event’ much more readily agrees with a complexity informed understanding of the term in contrast to the quasi‐religious definition which Badiou uses. This complexity‐informed understanding of the event illustrates that what the event reveals is simultaneously a dearth and wealth of possibilities yet to be realized. Therefore the event cannot be depended upon to produce novelty. However, the notion of the event must not be discarded too quickly; classical science has traditionally discarded this idea due to its reductive approach. The idea of process opens up an understanding of the radical novelties produced in history to the possibility of the event and to a new understanding of ontology. This dissertation proposes that one can begin to think about radical forms of novelty without the event through the notion of experimentation. This approach allows one to engage with what exists rather than relying upon an event to produce novelty. This argument is made by following Bataille, who argues that through an engagement with non‐utilitarian forms of action, by expending for the sake of expenditure, the world is opened up to possibilities which remain unrealized under the current hegemony. In this light, this dissertation begins to develop a definition of novelty as that which forces a rereading of the system’s history.
AFRIKAANSE OPSOMMING: Hierdie proefskrif onderneem hoofsaaklik om die omstandighede waaronder nuwigheid binne ʼn stelsel ontstaan te verstaan. Daar word in die klassieke filosofie voorgehou dat nuwigheid gewoonlik vanuit ʼn gebeurtenis ontstaan. Die idee van ʼn gebeurtenis hou egter dikwels ongewenste metafisiese en konserwatiewe implikasies in. Hierdie proefskrif onderneem dus om, deels, ʼn benadering tot nuwigheid te ontwikkel wat onafhanklik van die gebeurtenis staan. Hierdie benadering word verder uitgebrei met behulp van insigte vanuit die Kritiese Kompleksiteits‐ en Post‐Strukturalistiese filosofie. Tot onlangs het die model van die raamwerk die wyse waarop daar oor die beperkinge van die konteks‐spesifieke aard van kennis in die sosiale wetenskappe gedink word oorheers. In hierdie proefskrif word voorgehou dat die idee van ʼn ‘ekonomie’ in plaas van die analogie van ʼn raamwerk hier gebruik behoort te word, omdat dit ons sal toelaat om die verhoudings binne die modelle wat deur sosiale wetenskaplikes gebruik word beter te verken. Verder word die moontlike verbande tussen Jacques Derrida , die kompleksiteitsfilosoof Edgar Morin en Georges Bataille teen hierdie agtergrond verken. Wanneer daar van ʼn ekonomie gepraat word, moet die oormaat van die ekonomie altyd in ag geneem word. Hierdie oormaat ontwrig altyd die ekonomie waarby dit uitgesluit word. Om te wys hoe die stelsel van so ʼn oormaat gebruik maak om by sy omgewing aan te pas, sal terminologie wat in die konteks van kompleksiteitsteorie ontwikkel is gebruik word. As gevolg van die oorvloed binne ʼn stelsel sal daar nooit ʼn volledige model van die stelsel ontwikkel kan word nie ‐‐ fasette van die stelsel sal altyd vir die waarnemer verborge bly. Verder sal die werk van Alain Badiou, wie se filosofie rondom die idee van nuwigheid wat uit ʼn gebeurtenis ontstaan gesentreed is, in hierdie verhandeling bespreek word. Die implikasies van die idee dat nuwigheid van die gebeurtenis afhanklik is word uitgelig deur die verwantskappe tussen die werke van Derrida en Badiou te bespreek. Derrida se gebruik van die term ‘gebeurtenis’ dra ʼn noue verwantskap met kompleksiteitsteorie, en dit word teenoor Badiou se amper‐godsdienstige gebruik van die term gestel. Daar word aangevoer dat daar binne ʼn kompleksiteits‐ingeligte verstaan van ʼn gebeurtenis beide ʼn skaarste en ʼn oorvloed van moontlikhede bestaan wat vervul kan word. Daarom kan daar juis nié op die gebeurtenis staatgemaak word om nuwigheid te skep nie. Die idee van die gebeurtenis moet egter nie te gou verwerp word nie. As gevolg van die klassieke wetenskap se reduksionisme is die idee van ʼn gebeurtenis tradisioneel ontken. Daarteenoor ontsluit die idee van ʼn proses die moontlikheid van radikale nuwighede in die geskiedenis as gevolg van ʼn verstaan van die gebeurtenis wat tot ʼn nuwe verstaan van die ontologie lei. Hierdie proefskrif stel dus voor dat ons voortaan aan radikale nuwigheid dink in terme van die denkbeeld van eksperimentering eerder as in terme van die gebeurtenis. Eksperimentering laat ons toe om te werk met wat ons het, eerder as om op ʼn gebeurtenis te moet wag. Na aanleiding van Bataille is die voorstel dat daar deur om te gaan met nieutilitaristiese vorms van optrede nuwe geleenthede vir die wêreld oopgemaak word; geleenthede wat onder die huidige hegemonie ongerealiseerd sal bly. In hierdie verband stel die proefskrif ʼn definisie van nuwigheid voor as dít wat mens dwing om die geskiedenis van ʼn stelsel te herformuleer.

ENGLISH ABSTRACT: This dissertation departs from the argument that an encounter with complexity exposes the breakdown of traditional doctrines that have been taken for granted for too long (markedly modernist reductionism). Contrary to reductionist strategies that rely on the methods of analysis and isolation, the study of complex phenomena focuses on the dynamic relations and organisation of systems and their environments. Although the proliferation of ideas concerning the notion of complexity is abundant, there is no agreed upon definition that informs an overarching ‘Theory of Complexity.’ This problem is addressed by following the historical development in the field of systyms thinking. A distinction is made between ‘restricted’ and ‘general’ theories of complexity. The study problematises the conceptual and empirical difficulties of studying complex phenomena. The impossibility of being able to have complete knowledge of complex systems is discussed in detail. It is argued that although the study of complexity serves as an alternative approach to reductionist approaches, our knowledge of complexity in principle remains a reduction thereof. This insight leads to the claim that the study of complex phenomena is at best a post-reductionist effort, which is necessarily a critical position. It is argued that the ‘complexity approach’ coincides with other poststructural approaches in the field of philosophy in general and with deconstruction in particular. However, situating the complexity approach within poststructuralism is not unproblematic, seeing that poststructural forms of critique are marred by problems of legitimation. Allegiance to postmetaphysical ideals implies that objective grounds for justifying or warranting the choice of norms from where to launch critical inquiry are sacrificed. A deconstructive reading of the Kantian concept of ‘critique’ reveals a double movement that is at work in the concept. This double bind displaces the definition of critique to change to mean ‘critique as stricture.’ From this perspective the logic of différance is at work in critical analysis and the limitations of our meaning making strategies are exposed. It is suggested that ‘critique as stricture’ is a poststructural form of critical inquiry that regains legitimacy by operating in the tension of the force field created by antagonistic positions. A provisional grounding in the name of the limit emerges. The kind of thinking that can be cognisant of this general movement of ‘critique as stricture’ is found in the notion of ‘complex thinking.’ By drawing on Derrida’ and Morin’s reappropriation of Bataille’s distinction between the restricted and general economy, it is demonstrated how complex thinking is operating within the movement of the general economy. The study concludes with the argument that informed by ‘critique as stricture,’ the complexity approach progresses to what Cilliers calls ‘critical complexity.’ This brand of complexity distinguishes itself by a normative turn, which is distinguished by three imperatives: 1) the Provisional Imperative, 2) the Critical Reflexive Imperative and 3) the World-disclosing Imperative. All of these operate under the influence of the general economy, which allows critical inquiry to be grounded and legitimised in the tension of thinking antagonistic positions together without reducing them to one another.
AFRIKAANSE OPSOMMING: In hierdie proefskrif word aangevoer dat die verskynsel van kompleksiteit die disintegrasie van tradisionele leerstellings se aansprake, wat te lank as vanselfsprekend aanvaar was, ontbloot (merkbaar reduksionistiese modernisme). In teenstelling met reduksionistiese strategieë wat staat maak op metodes van analise en isolasie, fokus die studie van komplekse verskynsels op die dinamiese verhoudings en organisasie van sisteme en hul omgewings. Alhoewel die studie van kompleksiteit ’n byna alledaagse verskynsel geword het, bestaan daar geen bindende definisie wat ’n enkele ‘Teorie van Kompleksiteit’ daarstel nie. Daar word spesifiek op hierdie probleem gefokus in terme van hoe die wetenskaplike studie van kompleksiteit histories ontwikkel het. Dit word aangevoer dat dit sinvoller is om eerder tussen ‘beperkte’ en ‘algemene’ teorieë van kompleksiteit te onderskei as om ’n oorkoepelende teorie te ontwikkel. Heelwat probleme duik op in die poging om komplekse verskynsels konseptueel en empiries te bestudeer. Alhoewel die studie van komplekse verskynsels ’n alternatiewe posisie tot reduksionistiese benaderings daarstel, kan kennis van kompleksiteit in beginsel slegs ’n reduksie daarvan wees. As gevolg hiervan word die studie van komplekse verskynsels ten beste as ’n post-reduksionistiese poging beskryf wat noodwendig ’n kritiese posisie impliseer. Die kompleksiteitsbenadering stem in die algemeen met post-strukturele filosofiese benaderings, en spesifiek met dekonstruksie ooreen. Hierdie ooreenstemming is egter nie onproblematies nie, aangesien post-strukutrele kritiese posisies deur probleme van legitimasie gekenmerk word. Lojaliteit aan post-metafisiese ideale het tot gevolg dat daar geen objektiewe, grondige vertrekpunt bestaan vanwaar normatiewe begrondings geregverdig kan word nie. ’n Dekonstruktiewe lees van Kant se idee van die begrip ‘kritiek’ openbaar dat daar ’n ‘double movement’ aan die werk is wat die konsep ‘kritiek’ kan verruim ten einde dit te verander om ‘critique as stricture’ te beteken. Die werking van différance is altyd betrokke tydens kritiese analise waardeur die beperkinge van ons singewende strategieë blootgestel word. Hierdie her-definiëring van kritiek as ‘critique as stricture’ stel ons in staat om nuwe lewe in die kritiese projek te blaas deurdat legitimiteit gevind word in die spanning van die kragveld wat geskep word tussen antagonistiese posisies. ’n Voorlopige grondslag word in die naam van die beperkings van ons denkstrategië gevestig. ‘Kompleksiteitsdenke’ (‘complex thinking’) stel ’n denkstrategie daar wat tred hou met die dinamiese beweging wat in ‘critique as stricture’ teenwoordig is. ‘Kompleksiteitsdenke’ word aan die hand van Derrida en Morin se interpretasie van Bataille se onderskeid tussen die beperkte en algemene ekonomie gedoen ten einde te demonstreer dat ‘kompleksiteitsdenke’ binne die beweging van die algemene ekonomie val. Die studie word afgesluit met die argument dat, ingelig deur ‘critique as stricture’, die kompleksiteitsbenadering tot die begrip ‘kritiese kompleksiteit’ ontwikkel soos voorgestel deur Cilliers. Kritiese kompleksiteit word deur ’n normatiewe impuls gekenmerk wat in sigself weer deur drie noodsaaklike eienskappe uitgeken kan word: 1) die Voorlopige Imperatief, 2) die Kritiese Refleksiewe Imperatief en 3) die Wêreld-ontsluitende Imperatief. Al drie hierdie imperatiewe staan onder die invloed van die algemene ekonomie wat ons toelaat om kritiese analise te begrond in die spanning wat onstaan wanneer antagonistiese konsepte saam gedink word sonder dat hulle tot mekaar gereduseer word.

Full textAbstract:
Coupling Between Objects and Cyclomatic Complexity have long been used to measure software quality and predict maintainability and reliability of software systems prior to release. In particular, Coupling Between Objects has been shown to correlate with fault-proneness and maintainability of a system at the class level. We propose a new set of metrics based on a fusion of Coupling Between Objects and Cyclomatic Complexity that can be superior to Coupling Between Objects alone at predicting class quality. The new metrics use Cyclomatic Complexity to 1) augment Coupling Between Objects counting to assign a strength of a coupling between two classes and 2) determine the complexity of a method invocation chain through the transitive relation of invocations involved in a coupling. This results in a measure that identifies objects that are coupled to highly complex methods or method invocation chains. The metrics were implemented as an Eclipse Plug-in and an analysis of two industry Java projects, ConnectorJ and Hibernate, demonstrates the correlation between the new metrics and post-release defects identified in system change logs.

Full textAbstract:
Complex systems are characterised by different distinguishing aspects often associated with completely separate behaviours. In financial markets, paramount example of complex systems, two of these aspects stand out in characterising the statistical properties of the many constituents: one is multifractality, a feature which describes the departure of financial time series from purely random processes and is therefore a measure of complexity of the prices; the other is the cross-correlation structure between assets, which encloses information about the market organisation and can reveal dominant factors as well as hierarchical properties. In this thesis I have studied the relationship between these two distinctive properties of financial markets. I have first unveiled new empirical properties of stock returns, casting new light on the latent mechanism governing price dynamics and interactions, and I have then proposed a model which reproduces the observed properties. I have investigated multifractality dynamically on stock returns after having introduced the weighted generalised Hurst exponent, a study that has revealed remarkable increasing trends in the dynamical scaling exponents for firms bailed-out after the 2008 financial crisis. I have then tested the significance of dynamical fluctuations of multifractality against a well-established multifractal model, the Multifractal Random Walk (MRW). The hypothesis of constant multifractality in financial markets has been rejected in many cases revealing a much more complex behaviour of financial time series. I have then linked the multifractal behaviour in financial markets to the cross-correlation structure, showing that the two properties are indeed related. I have investigated the relationship between a proxy of multifractality and cross-correlation hierarchical properties on different markets which have confirmed the result. After having thoroughly reviewed the existing literature on multivariate models, I have proposed a dynamical multivariate model able to reproduce the empirical facts reported in this thesis along with an array of other well-established stylised facts, thus unifying correlation and multifractality in a unique coherent framework.

Full textAbstract:
To achieve a high level of performance and efficiency, contemporary aerospace systems must become increasingly complex. While complexity management traditionally focuses on a product’s components and their interconnectedness, organizational representation in complexity analysis is just as essential. This thesis addresses this organizational aspect of complexity through an Organizational Complexity Metric (OCM) to aid complexity management. The OCM augments Sinha’s structural complexity metric for product architectures into a metric that can be applied to organizations. Utilizing nested numerical design structure matrices (DSMs), a compact visual representation of organizational complexity was developed. Within the nested numerical DSM are existing organizational datasets used to quantify the complexity of both organizational system components and their interfaces. The OCM was applied to a hypothetical system example, as well as an existing aerospace organizational architecture. Through the development of the OCM, this thesis assumed that each dataset was collected in a statistically sufficient manner and has a reasonable correlation to system complexity. This thesis recognizes the lack of complete human representation and aims to provide a platform for expansion. Before a true organizational complexity metric can be applied to real systems, additional human considerations should be considered. These limitations differ from organization to organization and should be taken into consideration before implementation into a working system. The visualization of organizational complexity uses a color gradient to show the relative complexity density of different parts of the organization.

Thesis (PhD)--Stellenbosch University, 2011.ENGLISH ABSTRACT: Globalisation, rapid changes in technology, and demographic trends are all important factors that contribute to conditions that require adaptive capacity in military organisations. The context of a majority of military operations is often asymmetric with blurred boundaries, and military organisations are expected to master a wide range of operations from humanitarian disaster relief to more regular warlike situations in a joint- and multinational framework. The complexity of the challenges facing military leaders in contemporary and future operations makes it relevant to develop a meta-competency model for leadership in complex military systems, which is the main purpose of this dissertation. A Complexity Approach represents a shift from a set of conservative laws to a perception of the world as an open and highly dynamic system, and some characterise complexity as a bridge between modernism on the one hand and post-modernism on the other. Complexity and complex systems have a number of characteristics, some of them being a large number of short-ranged interactions that are dynamic, non-linear and fairly rich. Another significant feature of complexity is the emphasis on emergent patterns that are codetermined through a dynamic process between the history of the system and the interaction with its local environment. Leadership in complex systems might be described by the dynamics of emergence, not merely by incremental influence, and increasingly considered to be a collective social phenomenon. A complexity-oriented leader acts as an enabler of a rich identity interacting in richly constrained play of difference, facilitating “bounded” individual and systemic adaptive capacity. The reigning paradigm in military organisations, however, are closely linked to an autocratic and bureaucratic structure and a fundamental quest for control, equilibrium and stability, all of which are deeply embedded in Newtonian Principles of linearity, reductionism and determinism. The investigation of empirical research on Norwegian Military Officers and the Norwegian Armed Forces reveal a considerable amount of homogenous force substantiating stability and control, at the same time as complexity and uncertainty are acknowledged. This dissertation argues that the definition of competencies as “an underlying characteristic of an individual that is causally related to effective and/or superior performance in a job or situation”, is not suitable for a complexity understanding and proposes competencies to be defined as “interconnected underlying characteristics of an individual or system, which through a dynamic and non-linear process of interaction between local agents and the environment contribute to the emergence of identifiable or unidentifiable patterns of individual or systemic behaviour”. Based on a synthesis of a non-empirical literature study, empirical research and a modelbuilding study, this dissertation suggests that heterogeneity of degree, androgynousity, cognitive flexibility, ethical reasoning, cross-cultural competence, intuition, identity and courage, are necessary meta-competencies for leadership in complex military systems. It is further argued that these meta-competencies must be interpreted as interconnected and interdependent, and the metaphor of a cloud is therefore presented as a suitable image of the intricate dynamics of complexity.
AFRIKAANSE OPSOMMING: Globalisering, vinnige veranderinge in tegnologie en demografiese tendense is belangrike faktore wat bydra tot toestande wat aanpassingsvermoë in militêre organisasies vereis. Die konteks waarin ’n meerderheid militêre operasies hul bevind is dikwels asimmetries met onduidelike grense, en daar word van militêre organisasies verwag om ’n wye verskeidenheid krygsverrigtinge van humanitêre rampverligting tot meer gereelde oorlogsugtige omstandighede in ’n gesamentlike en multinasionale kader te bemeester. Die kompleksiteit van die uitdagings waarvoor militêre leiers te staan kom in huidige en toekomstige krygsverrigtinge is dit gepas om ’n meta-bevoegdheidsmodel vir leierskap in komplekse militêre stelsels te ontwikkel, wat die belangrikste doel van hierdie tesis is. ’n Kompleksiteitbenadering verteenwoordig ’n verskuiwing van ’n stel konserwatiewe wette na ’n waarneming van die wêreld as ’n oop en hoogsdinamiese stelsel, en kompleksiteit word soms gekenmerk as ’n brug tussen modernisme aan die een kant en die post-modernisme aan die ander. Kompleksiteit en komplekse stelsels het ’n aantal kenmerke, waarvan sommige van hulle ’n groot aantal kortafstandinteraksies wat dinamiese, nie-lineêre en redelik ryk is. Nog ’n belangrike kenmerk van kompleksiteit is die klem op die ontluikende patrone wat vasgestel word deur middel van beide ’n dinamiese proses tussen die geskiedenis van die stelsel en die interaksie met die plaaslike omgewing. Leierskap in komplekse stelsels kan beskryf word deur die dinamika van verskyning, nie net deur inkrementele invloed nie, en al hoe meer beskou as ’n kollektiewe sosiale verskynsel. ’n Kompleksiteitgeoriënteerde leier dien as ’n instaatsteller van ’n ryk identiteit wat wisselwerking uitoefen in streng beperkte verskilspel, wat “begrensde” individuele en sistemiese aanpassingsvermoë fasiliteer. Die huidige paradigma in die militêre organisasies word egter nou gekoppel aan ’n outokratiese en burokratiese struktuur, en ’n fundamentele soektog vir beheer, ewewig en stabiliteit, waarvan almal diep in Newtoniaanse Beginsels van lineariteit, reduksionisme en determinisme vasgelê is. Die ondersoek van empiriese navorsing oor die Noorse Militêre Offisiere en die Noorse Weermag openbaar ’n aansienlike aantal homogene mag wat stabiliteit en beheer staaf, terselfdertyd as wat kompleksiteit en onsekerheid erken word. Hierdie tesis is van mening dat die definisie van vaardighede as “’n onderliggende eienskap van ’n individu wat oorsaaklik verwant is aan doeltreffende en/of superieure prestasie in ’n beroep of situasie”, nie geskik is vir ’n kompleksiteitbegrip nie en stel voor dat vaardighede gedefinieer word as “onderling verbinde onderliggende eienskappe van ’n individu of stelsel, wat deur middel van ’n dinamiese en nie-lineêre proses van interaksie tussen plaaslike agente en die omgewing bydra tot die verskyning van identifiseerbare of nie-identifiseerbare patrone van individuele of sistemiese gedrag”. Gebaseer op ’n sintese van ’n nie-empiriese literatuurstudie, empiriese navorsing en ’n bou van modelle studie, stel hierdie tesis voor dat die heterogeniteit van graad, androgienisme, kognitiewe buigsaamheid, etiese beredenering, kruis-kulturele bevoegdheid, intuïsie, identiteit en moed, nodige meta-vaardighede vir leierskap in komplekse militêre stelsels is. Dit voer verder aan dat hierdie meta-vaardighede vertolk moet word as onderling verbinde en onderling afhanklik is, en die metafoor van ’n wolk word dus voorgestel as ’n geskikte beeld van die ingewikkelde dinamika van kompleksiteit.

Full textAbstract:
Many aspects contribute to make financial markets one of the most challenging system to understand. The aim of this thesis is to study some aspects of their complexity by focusing on univariate e multivariate properties of log-returns time-series, namely multifractality and cross-dependence. In this thesis, we started by performing a thorough analysis of the scaling properties of synthetic time-series with different known scaling properties. This enabled us to do two things: find the presence of a strong bias in the estimation of the scaling exponents, and interpret measurement on real data which led us to uncover the true source of the multifractal behaviour of financial log-prices, which has been long debated in the literature. We addressed the presence of the bias by proposing a method which manages to filter out its presence and we validate it by applying it to synthetic time-series with known scaling properties and on empirical ones. We also found that this bias is due to the stability under aggregation of the log-returns which, due to their long memory, are processes which for high aggregation tend to a random variable which displays an exact multifractal scaling. Finally we focused the attention on linking the scaling properties of log-returns to their cross-correlation properties within a given market finding an intriguing non-linear relationship between the two quantities.

Through examining the variables that contribute to the natural process of language and cognition, a promising path is paved for researchers to identify the variables that influence higher order skills, such as perspective taking, empathy and altruism. The current study implemented the PEAK Relational Training System Transformation Module Pre-Assessment Expressive portion (PEAK-T PA) as an objective behavior measure of relational framing complexity. Two additional self-report assessments were used with all subjects, including a multi-dimensional measure of empathy, referred to as the Interpersonal Reactivity Index (IRI) and the Valued Living Questionnaire (VLQ). A Pearson correlation analysis was conducted to examine the relationship between PEAK-T PA scores and IRI subscale scores. Additional Pearson correlation analysis was used to determine a relationship between PEAK-T scores and VLQ scores. A statistically significant relationship was determined between one of the relational frame subareas of the PEAK-T PA and the perspective taking IRI subscale scores. Results, limitations and future research areas associated with relational framing abilities are discussed.

Full textAbstract:
The estimation of the frequency and phase of a complex exponential in additive white Gaussian noise (AWGN) is a fundamental and well-studied problem in signal processing and communications. A variety of approaches to this problem, distinguished primarily by estimation accuracy, computational complexity, and processing latency, have been developed. One class of approaches is based on the Fast Fourier Transform (FFT) due to its connections with the maximum likelihood estimator (MLE) of frequency. This thesis compares several FFT-based approaches to the MLE in terms of their estimation accuracy and computational complexity. While FFT-based frequency estimation tends to be very accurate, the computational complexity of the FFT and the latency associated with performing these computations after the entire signal has been received can be prohibitive in some scenarios. Another class of approaches that addresses some of these shortcomings is based on linear regression of samples of the instantaneous phase of the observation. Linear- regression-based techniques have been shown to be very accurate at moderate to high signal to noise ratios and have the additional benefit of low computational complexity and low latency due to the fact that the processing can be performed as the samples arrive. These techniques, however, typically require the computation of four-quadrant arctangents, which must be approximated to retain low computational complexity. This thesis proposes a new frequency and phase estimator based on simple estimates of the zero-crossing times of the observation. An advantage of this approach is that it does not require arctangent calculations. Simulation results show that the zero-crossing frequency and phase estimator can provide high estimation accuracy, low computational complexity, and low processing latency, making it suitable for real-time applications. Accordingly, this thesis also presents a real-time implementation of the zero-crossing frequency and phase estimator in the context of a time-slotted round-trip carrier synchronization system for distributed beamforming. The experimental results show this approach can outperform a Phase Locked Loop (PLL) implementation of the same distributed beamforming system.

Full textAbstract:
This research focuses on project complexity with the aim to better understand it and to highlight the factors that affect/contribute to it. In addition, this research also highlights key project management practices and project critical success factors considered important to manage project complexity/complex projects. The two main motivating factors behind this research were, the lack of understanding of complex projects and the lack of relevance of project management theory to practice, which have been highlighted by many researchers. Since projects in different sectors are increasingly being characterised as complex, this entails a better project management knowledge base focusing on the dynamic, social and complex contexts of projects, so that the interrelationships, interdependencies and uncertainties between different project interfaces can be understood and managed properly. In order to understand this 'project actuality', it was necessary to obtain the views from practitioners working in these project settings and managing project dynamics and intricacies. To establish this pragmatic view, a series of interviews and questionnaire surveys was carried out and all efforts were made to select the participants working on complex projects with complex products falling under the Complex Product Systems (CoPS) category which was the case in the 2nd phase interviews and questionnaire, whereas in the 1st phase practitioners with industrial experience and also involved and/or in the process of getting academic qualification in project management were preferred. The first phase helped in establishing the theoretical and pragmatic perspective and the 2nd phase in refining and validating the findings. The questions were inline with the research focus mentioned earlier.The main findings of the research show that the perception of project complexity and its contributing factors were very much influenced by the project context, i.e. from organization level to work discipline level. No difference in the practitioners' perception of project complexity and its contributing factors was observed among the practitioners based in a similar organization and project setting. Novelty was found to be one of the key project complexity characteristics related to three project elements-people, product and process. In terms of key project management practices and skills considered important in managing project complexity, soft skills were reported useful by majority of the participants. The key processes found useful were either the ones which focused on people or others which helped to manage changes/deviations in projects. Influence and relationship, delegation, flexibility and trust were the main project critical success factors which emerged out of this research for complex projects.

Thesis (MPhil)--Stellenbosch University, 2014.ENGLISH ABSTRACT: Organisations are faced with ever increasing complexity. While there are many responses to complexity just as there are many definitions of complexity this thesis highlights the use of agile software development as a useful method. The case of agile software development is influenced by its people first approach and minimal process implementation to implement constraints in which phenomena of complexity can be understood. Chapter 1 introduces why complexity is relevant in the organisation today and the issues associated with complexity. A basic introduction to agile software development and why it is a response to complexity is tabled. Chapter 2 investigates the concepts of complexity. To highlight the difference between linear and non-linear systems and reductionistic thinking the ideas that not all things are complex is explored. Key concepts of complex systems are described to come to a better understanding of what entails a complex system. Information theory and dynamic systems are discussed including system attributes such as attractors and bifurcations. Finally the theory of complex adaptive systems is presented and a classification of all complexity theories is tabled. Chapter 3 is centred on agile software development, presenting practices and processes as a understanding of how agile software development is applicable to complexity. Three agile methods are identified. Chapter 4 presents the ideas of modelling and limits to understanding. Models of complex systems are useful but are limited, due to the properties of complex systems. The concept of mental models leads to models of organisations and how leaders need to help with transformation of these models towards models that are more aligned to agile type thinking. Chapter 5 looks at the core concepts, and practices of agile applied to complexity and why these are relevant in responding to complexity. Towards the end of chapter the role of narrative is explored in the terms of problem definition and solutioning in complex systems. Chapter 6 concludes the thesis with insights where agile software development is an appropriate response to complexity and the conditions in which it is not.

Met eienskappe soos “mense/verbruiker/gebruiker – eerste” benadering asook minimale proses implementering, verskaf aanpasbare sagteware ontwikkeling die raamwerk waar binne die konsep kompleksiteit verstaan kan word. Hoofstuk 1 bespreek die kwessies rondom kompleksiteit en die relevansie daarvan in organisasies vandag. Verder word aanpasbare sagteware ontwikkeling kortliks bespreek en hoe dit gebruik kan word om kompleksiteit te verstaan, word getoon. Hoofstuk 2 ondersoek die verskillende konsepte random kompleksiteit. Daar word gekyk na linêre en nie-linêre stelsels asook die oortuiging dat nie alle dinge kompleks is nie word geondersoek. Sleutel kenmerke van komplekse stelsels word beskryf om sodoende ‘n better begrip te kry van wat ‘n komplekse stelsel behels. Informasie teorie en dinamiese stelsels word bespreek, insluitend kenmerke soos “attraktors” en “bifurkasies”. Laastens, word die teorie rondom komplekse aanpasbare stelsels bespreek en ‘n klassifikasie van alle komplekse teorieë word uiteengesit. Hoofstuk 3 fokus op “agile software development” en hoe sulke praktyke en prosesse toepaslik is op kompleksiteit. Daaropvolgend word drie aanpasbare metodes ge-identifiseer en individueel bespreek. Hoofstuk 4 verduidelik die idees rondom modellering en grense van begrip. Modelle van komplekse stelsels kan nuttig wees, maar weens die eienskappe van komplekse stelsels, is die nuttigheid beperk. Die konsep van mentale modelle lei tot modelle van organisasies en hoe leiers hierdie modelle moet transformer na modelle wat meer in-lyn is met agile denkwyses. Hoofstuk 5 kyk na die kern konsepte en praktyke waar “agile” toegepas word tot kompleksiteit en waarom dit relevant is om kompleksiteit teen te werk. In die tweede helfde van die hoofstuk word die rol van narratief ondersoek in terme van probleem-identifisering en die soek na oplossings in komplekse sisteme. Hoofstuk 6 sluit af met insigte tot aanpasbare sagteware ontwikkelingsmetodes as toepaslike oplossing tot kompleksiteit asook die toestande waaronder dit geld.

Full textAbstract:
The complexity of dynamical systems (spanning brain, body and environment) can yield complex adaptive behaviors from non-linear interactions of individuals in space and time. A lack of reliable instruments to assess these varying behaviors results in inferences of how changes in behavior occurred over an extended period of time rather than being based on direct scientific measures. The aim of this study was to develop a scale of complexity and perceptual-cognitive skills' assessment in the sport soccer and to evaluate structural and criterion reliability. Based on the embodied cognition literature, the construct of this scale was identified with three dimensions to assess perceptual-cognitive performance of players when acting within different levels of complex team synergies. A sample of 10 soccer coaches - group A (n = 5 coaches; M = 24 yrs professional coaching experience) and group B (n = 5 coaches; M = 1 year of amateur coaching experience) were recruited to participate in the study. A total of 100 clips of 10 previously recorded soccer matches were analyzed in two assessment periods with one month between the end of the first assessment and the beginning of the second. This resulted in a combined total of 1000 measures used for the study. The results demonstrated that high skilled coaches were more reliable in the complexity dimension (r = 0.87) and also in the decision making dimension (r = 0.79) than low qualified coaches (r = 0.79) and (r = 0.71) respectively; and the complexity dimension was more stable across trials between professional and amateur coaches in the first data collection i (r = 0.79) and second data collection (r = 0 .73) than the decision making dimension (r = 0.50) and (r = 0.43) respectively. These findings indicate that this scale is reliable across applications and at different times with high and low qualified coaches. The use of the scale may be useful for identifying elements of emerging complexity at the team-fractal-player level; determine a perceptual-cognitive profile in athletes; and to better understand complex tactical dynamics in soccer.

Full textAbstract:
The Ningaloo Reef is Australia’s largest fringing coral reef and an iconic tourist destination; however tourism development in Ningaloo has been ad hoc and the area is challenged by human pressure on numerous fronts. In response to these challenges a number of research agencies brought together a range of scientists to study the effects of human interaction on the reef. Moving from research to practice has been understood to depend on the adaptive capacity of the institutions responsible for governing human activities, in this case in the Ningaloo area. Knowledge transfer describes the suite of strategies used to try to bridge the gap between research and management. Knowledge transfer efforts, however, seldom have the desired impact of seeing research applied to decision-making. The ubiquity of knowledge transfer difficulties across disciplines suggests a common root to the problem, based in our shared cultural assumptions. This study pairs a multidisciplinary theoretical investigation with action research to shed light on why knowledge transfer efforts so often fall short in terms of seeing research applied to practice.
Recent environmental management perspectives on knowledge transfer illustrate the shift towards stakeholder participation as a means of improving knowledge transfer success. As such, the action research study involved the researcher embedding herself in the Ningaloo community for 18 months, adopting the role of a knowledge broker and engaging and collaborating with modelling researchers and local stakeholders on knowledge transfer efforts. However, despite intensive stakeholder engagement, evaluation interviews at the end of the process indicated that although the knowledge transfer process had the effect of catalysing relationships between stakeholder groups in the region, and between regional stakeholders and scientists, it appeared to have relatively little effect on the representational knowledge of local stakeholders or the actual application of research in practice. This led to the question of whether knowledge transfer is itself is part of the research uptake problem, as per the principles of problem formulation, which specify that resolving seemingly intractable problems requires examining the assumptions that underpin our thinking about the problem situation.
On this basis, the theoretical component of this study explored the Newtonian assumptions that inform our understanding of knowledge transfer. An alternative complexity-based ontology is proposed, unifying the metaphysics of materialism and idealism, based on a synthesis of process philosophy, mathematical logic, quantum theory, general systems theory and the complexity sciences. The phenomena of cognition, learning, knowledge and organising are compared in relation to how they’ve been understood within the Newtonian paradigm, and how they are now being explained from the perspective of a complexity-based paradigm. By reframing the action research results from a complexity perspective, the Ningaloo knowledge transfer process does not constitute a failure in terms of enhancing the capacity of the Ningaloo system to make more sustainable decisions. Rather, the increased connectivity between stakeholder groups and scientists can be viewed as more importantly enhancing the creative capacity of Ningaloo’s governance system. It is posited that the research uptake problem should be reformulated from the basis of complexity paradigm, and the notions of knowledge transfer and adaptive capacity reconceptualised accordingly. Instead of devising rational objective arguments for someone else to improve the ‘adaptive capacity’ of human systems, scientists should focus instead on improving their own creative capacity in their local interactions.

Thesis (MA (Philosophy))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: This thesis is a philosophical exposition of violence informed by two theoretical positions which confront complexity as a phenomenon. These positions are complexity theory and deconstruction. Both develop systemsbased understandings of complex phenomena in which relations of difference are constitutive of the meaning of those phenomena. There has been no focused investigation of the implications of complexity for the conceptualisation of violence thus far. In response to this theoretical gap, this thesis begins by distinguishing complexity theory as a general, trans-disciplinary field of study from critical complexity theory. The latter is used to develop a critique and criticism of epistemological foundationalism, emphasising the limits to knowledge and the normative and ethical dimension of knowledge and understanding. The epistemological break implied by this critique reiterates the epistemological shift permeating the work of, among others, Friedrich Nietzsche and Jacques Derrida. In this context, critical complexity theory begins to articulate the idea of violence on two levels: first, as an empirical, ethical problem in the system; and, secondly, as asymmetry and antagonism. Violence in this second sense is implicated in the dynamic relations of difference through which structure and meaning are generated in complex organisation. The sensitivity to difference and violence shared by critical complexity theory and deconstruction allows for the parallel reading of these philosophical perspectives; and for the supplementation and opening of critical complexity theory by deconstruction within the architecture of this thesis. This supplementation seeks to preserve the singularity of each perspective, while exploring the potential of their points of affinity and tension in the production of a coherent philosophical analysis of violence. Deconstruction offers a more developed understanding of violence and a wealth of related motifs: différance, framing, law, singularity, aesthetics and others. These motifs necessitate the inclusion of other philosophical voices, notably, that of Nietzsche, Arendt, Kant, Levinas, and Benjamin. In conversation with these authors, this thesis links violence to meaning, to its possibility, to its production and to the process by which meaning comes to change. Given these links, violence is conceptualised in relation to the notion of difference on three distinct levels. The first is the difference between elements in a complex system of meaning; the second is the notion of difference between systems or texts around which boundaries or frames can be drawn; and the third is the notion of difference between meaning and the absence of meaning. This discussion examines the relationship between this violence implicated in the constitution of meaning and the more colloquial understanding of violence as atrocity, as rape, murder and other socially, politically and ethically problematic expressions thereof. It is to empirical violence, following Derrida and Levinas, that we are called to respond and to intervene in the suffering of the other. The ethical and political necessity of response anchors this discussion of violence. And, it is towards the possibility of an adequate response – the possibility of an ethics sensitive to its own violence and a politics that is directed at the eradication of empirical violence – which this discussion navigates.
AFRIKAANSE OPSOMMING: Hierdie tesis is ’n filosofiese uiteensetting van geweld wat deur twee denkwyses ingelig word wat kompleksiteit as fenomeen konfronteer. Hierdie denkwyses is kompleksiteitsteorie en dekonstruksie. Altwee ontwikkel sisteemgebaseerde verduidelikings van komplekse fenomene waar verhoudings van verskille die betekenis van hierdie fenomene beslaan. Daar is tot dusver nog geen gefokusde ondersoek na die implikasies van kompleksiteit vir die konsepsualisering van geweld nie. As antwoord op hierdie teoretiese leemte, begin hierdie tesis deur kompleksiteitsteorie as ’n algemene, trans-dissiplinêre studierigting van kritiese kompleksiteitsteorie te onderskei. Laasgenoemde word gebruik om kritiese denke van epistemologiese grondslae te ontwikkel, en beklemtoon die perke op kennis en die normatiewe en etiese aspek van kennis en verstaan. Die epistemologiese verwydering wat deur hierdie kritiek geïmpliseer word, herhaal die epistemologiese verskuiwing wat die werk van onder andere Friedrich Nietzsche en Jacques Derrida, deurdring. In hierdie konteks begin kritiese kompleksiteitsteorie om die konsep van geweld op twee vlakke te verwoord: eerstens as ’n empiriese, etiese probleem in die stelsel en tweedens as asimmetrie en antagonisme. Geweld in die tweede opsig word in die dinamiese verhoudings van verskil geïmpliseer, waar struktuur en betekenis in komplekse organisasie gegenereer word. Die sensitiwiteit vir verskil en geweld wat deur kritiese kompleksiteitsteorie en dekonstruksie gedeel word neem parallelle lesings van hierdie filosofiese perspektiewe in ag; sowel as die aanvulling en oopmaak van kritiese kompleksiteitsteorie deur dekonstruksie binne die struktuur van hierdie tesis. Hierdie aanvulling wil die enkelvoudigheid van elke perspektief bewaar, terwyl dit die potensiaal van hul punte van verwantskap en spanning in die produksie van ’n koherente filosofiese analise van geweld verken. Dekonstruksie bied ’n meer ontwikkelde verstaan van geweld en ’n rykdom van verwante motiewe: différance, beraming, wet, enkelvoudigheid, estetika en ander. Hierdie motiewe noodsaak die insluiting van ander filosofiese stemme, soos Nietzsche, Arendt, Kant, Levinas en Benjamin. Hierdie tesis tree in gesprek met hierdie skrywers en skakel geweld aan betekenis, aan die moontlikheid, aan die produksie en aan die proses waardeur betekenis na verandering lei. Gegewe hierdie skakels, word geweld in verhouding tot die begrip van verskil op drie spesifieke vlakke gekonsepsualiseer. Die eerste is die verskil tussen elemente in ’n komplekse stelstel van betekenis; die tweede is die begrip van verskil tussen stelsels of tekste waar grense of rame om getrek kan word; en die derde is die begrip van verskil tussen betekenis en die afwesigheid van betekenis. Hierdie bespreking stel ondersoek in na die verhouding tussen hierdie geweld wat in die samestelling van betekenis geïmpliseer word en die meer alledaagse verstaan van geweld as wreedardigheid, as verkragting, moord en ander maatskaplike, politiese en etiese problematiese uitdrukkings daarvan. Ons word geroep om op empiriese geweld, in navolging van Derrida en Levinas, te reageer en in te gryp om die lyding van ander te keer. Die etiese en politiese noodsaaklikheid van reaksie dien as grondslag vir hierdie bespreking van geweld. Uiteindelik beweeg hierdie bespreking nader aan die moontlikheid van ’n voldoende reaksie – die moontlikheid van ’n etiek wat sensitief vir sy eie geweld is en ’n politiek wat op die uitwis van empiriese geweld gerig is.

Full textAbstract:
Thesis (MA (Philosophy))--University of Stellenbosch, 2008.This thesis sets out to model the notion of group identity in terms of the theory of complexity. It is an attempt to speak meaningfully about a concept that needs to have a sense of stability in order to constitute an ‘identity’, but at the same time has to be able to change in order to adapt to changing circumstances – and indeed does change. This tension between stability and change is seen as a manifestation of the philosophical endeavour of ‘thinking the difference’ which, in this context, is understood to mean that if we are committed to thinking the difference (and thereby undermining the philosophy of the same) for ethical reasons, we have to speak of group identity itself in terms that preserve difference. That entails keeping the tensions inherent to the notion intact, rather than choosing to emphasise one end of the tension, thereby reducing the other. As such, identity is understood as being relational. While modelling group identity as a complex system two important tensions are identified: that of the inside-outside divide that is a function of the boundary-formation of the system and the traditional tension between agency and structure in the formation of identity. The emphasis on difference as constitutive of identity places the argument within poststructuralism as a school of thought. More specifically, the links that have been established between complexity theory and the work of Jacques Derrida is explored to unpack the implications these links would have for group identity. This application is done within the framework of time: first the issues of the past and the memory of the group are investigated to explore whether identity as a complex system can cope with its own tensions. The work of Derrida is employed to show how the memory of a complex system can be understood as the inheritance of the system. This is an ethical understanding which entails responsibility. Understanding the past in this way, it is argued, allows the future to be thought. This is the case, it is argued, because the future must be understood as a Derridean ‘new beginning’ which entails engaging with and deconstructing the past. Finally, this notion of the future as a new beginning is unpacked. It is defined as the group’s singular opportunity to allow for ‘real’ change, change that is only possible if the system is disrupted by its outside. It is argued that the complex system as a very particular open system can accommodate the possibility of the ‘new beginning’. This understanding of the system and its outside is brought in relation to Derrida’s understanding of the economy of the system and the future as a ‘new kind of writing’. The implications of this theory for the notion of autonomy are briefly addressed. In order to test the theory, the argument is applied throughout to the example of the Afrikaner as a group identity. In conclusion, suggestions are made as to how the Afrikaner could understand itself and its memories in order for the group identity to survive meaningfully and – more importantly – ethically.

Thesis (MscAgric (Horticulture))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: Commercial fig production with popular European cultivars, Bourjasotte Noire, Col de Damme Noire and Noire de Caromb, is new to the Western Cape. Little research on fig production has been conducted in South Africa and producers are struggling to implement effective commercial practices. In order to establish practices that will maximise yield of quality fruit, the most productive one-year-old shoot lengths were identified in a phenological study. All shoot length categories evaluated in ‘Bourjasotte Noire’ (10 – 15 cm, 25 – 40 cm, 50 – 65 cm, 75+ cm) yielded fruit and will probably yield well the following season. In ‘Col de Damme Noire’, shoots longer than 60 cm seem to be suited to reproduction, yet they might produce a poor yield the following season. Shoots 10 – 20 cm long in ‘Noire de Caromb’ are productive relative to their length, while shoots 30 – 50 cm and 60 – 80 cm long are also fairly productive. Shoots longer than 100 cm produced suitable shoot lengths for yield the following season. Two experiments were conducted on ‘Bourjasotte Noire’ and ‘Col de Damme Noire’ to establish the type (Experiment 1, different intensity heading cuts) and timing (Experiment 2) of pruning cuts required to stimulate the growth of shoots of the same length as the shoots selected to be optimal for yield in the phenology study, and to reduce the expression of distal branching. In ‘Bourjasotte Noire’, removing one third of the total length of one-year-old shoots on 21 July by heading stimulated the development of more growth and longer current season shoots compared to other treatments, while reducing yield slightly. Heading back to three nodes in ‘Col de Damme Noire’ stimulated the growth of current season shoots of the optimal length established in the phenology study, while heading cuts on 30 June produced the longest average current season shoot length in ‘Col de Damme Noire’. To further address the effects of distal branching (acrotony), an experiment was conducted to establish whether rest breaking agents (RBA’s) in combination with tip-pruning can increase tree complexity by improving bud break, and whether increased complexity would increase yield in all three cultivars. A second experiment was conducted to evaluate the effects of timing RBA applications on bud break and harvest scheduling. Lift® increased the number of buds breaking in ‘Bourjasotte Noire’, while in ‘Noire de Caromb’ Dormex® and oil increased bud break. Tip-pruning increased the average shoot length in ‘Bourjasotte Noire’ and ‘Col de Damme Noire’, while causing a reduction in the amount of new growth in ‘Noire de Caromb’. Lift® applied 3 August and Dormex® applied 30 June shortened the number of days to 50% bud break in ‘Bourjasotte Noire’ and ‘Col de Damme Noire’. Both Lift® and Dormex® applied on 30 June decreased the number of days to 50% bud break and 50% harvest of the breba crop in ‘Noire de Caromb’. These treatments increased the number of fruit in both the breba and main crop of ‘Noire de Caromb’, but reduced fruit size. In conclusion, different approaches with regards to pruning needs to be followed for each cultivar to establish or maintain the optimal shoots for reproduction, while RBA’s can be used to force earlier, increased- bud break and harvest of breba fruit.
AFRIKAANSE OPSOMMING: Kommersiele verbouing van drie Europese vykultivars, Bourjasotte Noire, Col de Damme Noire en Noire de Caromb is nuut tot die Wes-Kaap. Baie min navorsing oor die verbouing van vye is al in Suid-Afrika gedoen, met die gevolg dat produsente sukkel om effektiewe kommersiële verbouingspraktyke te implementeer. ‘n Fenologiese studie van die drie kultivars is uitgevoer om vas te stel wat die mees produktiewe een-jaar-oue lootlengte is, met die doel om die opbrengs van kwaliteit vrugte te maksimeer. Al vier kategorieë wat ge-evalueer is in ‘Bourjasotte Noire’ (10 – 15 cm, 25 – 40 cm, 50 – 65 cm, 75+ cm) is gevind om geskik te wees vir huidige en volgende seisoen opbrengs. Lote langer as 60 cm is geskik vir opbrengs in ‘Col de Damme Noire’ in die huidige seisoen, maar mag in die volgende seisoen swak presteer a.g.v. die gebrekkige lengte van nuwe lote wat daarop ontwikkel. In ‘Noire de Caromb’ is gevind dat lote 10 – 20 cm lank baie produktief is relatief tot hul lengte en dat lote 20 – 50 cm en 60 – 80 cm lank ook relatief produktief is. Lote langer as 100 cm was minder produktief, maar het nuwe lote gelewer wat geskik is vir opbrengs die volgende seisoen. Twee snoei eskperimente is uitgevoer op ‘Bourjasotte Noire’ en ‘Col de Damme Noire’ om vas te stel wat die mees geskikte tipe snoeisnit (Eksperiment 1, verskillende dieptes van topsnitte) en tydstip om te snoei (Eksperiment 2) is met die doel om lote te produseer soortgelyk in lengte aan die wat in die fenologie studie uitgewys is as die produktiefste, en om moontlik die voorkoms van “kaalnekke” te verminder. In ‘Bourjasotte Noire’ is gevind dat die wegsnoei van ‘n derde van die loot op 21 Julie aanleiding gee tot meer groei, langer een-jaar-oue lote en ‘n effense afname in opbrengs. Geskikte lote langer as 60 cm kan in ‘Col de Damme Noire’ verkry word deur lote te top sodat net drie nodes oorbly. Die uitvoer van topsnitte op 30 Junie het langer gemiddelde lootlengtes tot gevolg gehad. Om die probleem van “kaalnekke” (apikale dominansie) verder aan te spreek, is ‘n eksperiment uitgevoer om vas te stel of rusbreekmiddels gekombineerd met tip-snoei gebruik kan word om kompleksiteit te vermeerder deur knopbreek te verhoog, en indien wel, of dit sal aanleiding gee tot verhoogde opbrengs in al drie kultivars. ‘n Tweede eksperiment met verskillende toedieningstye van rusbreekmiddels is uitgevoer om vas te stel of oeste geskeduleer kan word. Lift® het knopbreek verhoog in ‘Bourjasotte Noire’, terwyl Dormex® en olie knopbreek verhoog het in ‘Noire de Caromb’. Tip-snoei het die gemiddelde lootlengtes verhoog in ‘Bourjasotte Noire’ en ‘Col de Damme Noire’, terwyl dit groei verminder het in ‘Noire de Caromb’. Lift® toediening op 3 Augustus en Dormex® toediening op 30 Junie het die aanvang van 50% knopbreek vervroeg in ‘Boujasotte Noire’ en ‘Col de Damme Noire’. Beide Lift® en Dormex® toediening op 30 Junie het die bereiking van 50% knopbreek- en 50% oes vervroeg in ‘Noire de Caromb’. Hierdie behandeling het ook die aantal vrugte van die breba- en hoofoes vermeerder, maar vruggrootte verminder. Verskillende snoeibenaderings behoort dus gevolg te word om vir elke kultivar die regte lootlengtes te genereer of te onderhou, terwyl rusbreekmiddels gebruik kan word om knopbreek te vervroeg en verhoog, en om die breba oes te vervroeg.

Full textAbstract:
Various ecological parameters, including soil pH, calcium, and habitat complexity have been suggested in the literature as having influence on land snail abundance and diversity. I compared relationships between 15 ecological parameters and snail abundance and diversity. 5,393 snails of 72 species were collected from 60 sites in 2007. Habitat observations were recorded in the field and soil core samples taken at each site and later analyzed for soil moisture, organic matter, cation exchange capacity, pH, calcium, magnesium, zinc, potassium, phosphorus, sulfur, boron, manganese, iron and copper. Statistical analyses were run using these soil factors plus a habitat complexity index (from combined values assigned to different levels of vegetation, topography and exposed rock), for a total of 15 parameters. To reduce the number of parameters and arrive at a more biologically meaningful model, Bayesian Information Criteria analysis (BIC) was run for abundance and diversity. The resulting best-fitted BIC model for abundance contained 3 parameters (pH, S, and habitat complexity) (R2 = 0.47), all of which were positively associated with abundance in a multiple regression analysis. For diversity, the best-fitted BIC model also contained 3 parameters (Ca, Fe, and habitat complexity) (R2 = 0.54). Ca and habitat complexity showed a positive association in the multiple regression analysis, but Fe was inversely associated with diversity, suggesting Fe could potentially act as an ecological limiting factor to it. These results suggest that land snail abundance and diversity are best treated separately in analyses, as they are influenced by different variables, with the exception of habitat complexity, which is suggested to have a positive association with both abundance and diversity. The regression model equations have potential value in that they can be used to predict snail abundance and diversity in areas that have not been assessed.
