There is a need for quantitative CT data in radiation therapy. Currently there are only few algorithms that address this issue, for instance the commercial DirectDensity algorithm. In scientific literature, an example of such an algorithm is DIRA. DIRA is an iterative model-based reconstruction method for dual-energy CT whose goal is to determine the material composition of the patient from accurate linear attenuation coefficients. It has been implemented in a two dimensional geometry, i.e., it could process axial scans only.  There was a need to extend DIRA so that it could process projection data generated in helical scanning geometries. The newly developed algorithm (DIRA-3D) implemented (i) polyenergetic semi-parallel projection generation, (ii) mono-energetic parallel projection generation and (iii) the PI-method for image reconstruction. The computation experiments showed that the accuracies of the resulting LAC and mass fractions were comparable to the ones of the original DIRA. The results converged after 10 iterations.

DIRA-3D is an iterative model-based reconstruction method for dual-energy helical CT whose goal is to determine the material composition of the patient from accurate linear attenuation coefficients (LACs). Possible applications are, for example, to aid in calculations of radiation transport and dose calculations in brachytherapy with low energy photons, and in proton therapy. There was a need to replace the current image reconstruction method, the PI-method, with a weighted filtered backprojection (wFBP) algorithm for image reconstruction, since wFBP is used for image reconstruction in Siemens's CT-scanners. The new DIRA-3D algorithm implemented the program take for cone-beam projection generation and the FreeCT wFBP algorithm for image reconstruction. Experiments showed that the accuracies of the resulting LACs for the DIRA-3D algorithm using wFBP for image reconstruction were comparable to the one using the PI-method for image reconstruction. The relative LAC errors reached a value below 0.2% after 10 iterations.

The aim of this thesis is to investigate strength and origin of the stabilization for various types of noncovalent interactions. As this knowledge could lead to a deeper understand- ing and rationalization of the binding phenomena. Further, to participate on the de- velopment of new noncovalent data sets, which are nowadays inevitable in the process of parametrization and validation of new computational methods. In all the studies, different binding motifs of model complexes, which represent usually crystal structures, structures from unrelaxed scans or the local minima, were investi- gated. The calculations of the reference stabilization energies were carried out at ab initio level (e.g. CCSD(T)/CBS, QCISD(T)/CBS). Further, the accuracy of more ap- proximate methods (e.g. MP2.5, DFT-D or SQM methods) toward reference method, was tested. In order to obtain the nature of the stabilization the DFT-SAPT decompo- sition was frequently utilized. In the first part of the thesis, the importance and basic characteristics of different types of noncovalent interactions (e.g. halogen bond, hydrogen bond, π· · · π interaction etc.), are discussed. The second part provides the description of computational methods which were essential for our investigation. The third part of the thesis provides an overview for part...

At some point during a creative action something clicks, suddenly the prospective problem solver just knows the solution to a problem, and a feeling of joy and relief arises. This phenomenon, called Eureka experience, insight, Aha moment, hunch, epiphany, illumination, or serendipity, has been part of human narrations for thousands of years. It is the moment of a subjective experience, a surprising, and sometimes a life-changing event. In this thesis, I narrow down this moment 1. conceptually, 2. experientially, and 3. temporally. The concept of emerging solutions has a multidisciplinary background in Cognitive Science, Arts, Design, and Engineering. Through the discussion of previous terminology and comparative reviews of historical literature, I identify sources of ambiguity surrounding this phenomenon and suggest unifying terms as the basis for interdisciplinary exploration. Tracking the experience based on qualitative data from 11 creative practitioners, I identify conflicting aspects of existing models of creative production. To bridge this theoretical and disciplinary divide between iterative design thinking and sequential models of creativity, I suggest a novel multi-layered model. Empirical support for this proposal comes from Dira, a computer-based open-ended experimental paradigm. As part of this thesis I developed the task and 40 unique sets of stimuli and response items to collect dynamic measures of the creative process and evade known problems of insightful tasks. Using Dira, I identify the moment when solutions emerge from the number and duration of mouse-interactions with the on-screen elements and the 124 participants' self-reports. I provide an argument for the multi-layered model to explain a discrepancy between the timing observed in Dira and existing sequential models. Furthermore, I suggest that Eureka moments can be assessed on more than a dichotomous scale, as the empirical data from interviews and Dira demonstrates for this rich human experience. I conclude that the research on insight benefits from an interdisciplinary approach and suggest Dira as an instrument for future studies.

One of the most critical challenges facing South Africa is the shortage of skills. The Financial Services Sector, of which banks form part, is also affected by this problem and this poses a risk in achieving the targeted Gross Domestic Product (GDP). The quality and level of education offered in South African Higher Education Institutions is perceived as being insufficient to that which is required in the industry and is a possible contributing factor towards the skills shortage problem. The study was motivated by the concerns raised by some scholars concerning the relevance of the management accounting syllabus as compared with the technical skills required in the banking industry. Investigating this is important as the Financial Services Sector, which includes the banking industry, is one of the largest employers of management accountants in South Africa and there is a paucity of research in this area. The aim of the study was to determine whether management accounting technical skills provided by an ODeL University in South Africa meet banking employers’ expectations. A qualitative research approach was used to conduct interviews with nineteen participants from three banks and ten academics from the ODeL University and includes a qualitative documentary analysis to review and analyse the study material for four management accounting modules and the mapping of the management accounting syllabus to the SAICA competency framework. The results reflect the data obtained from the interviews. The analysis of the interviews is organised under five main themes as follows: Function of management accounting within the banking sector; recruitment of graduates and development of management accounting technical skills; identified technical skills lacking in new graduates employed by banks; bank specific training at an ODeL institution (an academic perspective) and strategies to bridge the gap. The results of the analysis conducted on the management accounting study material from the ODeL University are presented in four categories; Costing, Financial Management, Accounting Data Processing and the SAICA Competency Framework. The results indicate that bank employers acknowledge the work achieved by higher education institutions in providing students with basic management accounting skills, which enable them to start working in management accounting positions in banks. However, bank participants were concerned with graduates’ inability to link theory with practical application and further confirmed that graduates lack a number of relevant technical skills. Academics confirmed that the management accounting syllabus does not give much attention to banks and other financial service industries; it is dominated by activities and case studies related to manufacturing industries. The analysis of the prescribed study material supports this and indicates that there are insufficient activities related to service companies and very few references to financial services sector entities. Several recommendations were made by participants which, inter alia include incorporating relevant activities and case studies into the management accounting syllabus and greater reciprocity between the banking industry and universities. This study contributes to the literature on management accounting technical skills’ relevance to banks and by extension, the financial services sector. It provides insights on the management accounting technical skills that are currently lacking in graduates. Additional areas warranting further research are also identified. / Omnye weyona micelimngeni enobuzaza ojongene noMzantsi Afrika kukunqongophala kwezakhono.

Die einddoel van die navorsing was om gevolgtrekkings te maak oor die verhoudingsdinamika (omvang en rigting) tussen die konsepte ten einde organisatoriese loopbaanontwikkelingspraktyke vir die kenniswerker voor te stel. ’n Kwantitatiewe deursneenavorsingsbenadering is gevolg en het ’n steekproef van N = 404 kenniswerkers behels wat by professionele Suid-Afrikaanse liggame geregistreer is. Beskrywende, korrelasie- en meerveranderlike inferensiële statistiek is ingespan. Aanvullend tot die kanoniese korrelasieresultate, het regressie and strukturele vergelykingsmodellering ontledings aangetoon dat die loopbaantevredenheidsprofiel unieke beïnvloedingsfaktore het terwyl die selfwaargenome indiensneembaarheidsprofiel ook oor sy eie unieke beïnvloedingsfaktore beskik. Moderering regressie-ontleding het gewys dat individue se loopbaankognisies (dit is die vlakke van loopbaanaanpasbaarheid en loopbaanpreokkupasies) nie voorwaardelik ten opsigte van hulle psigososiale loopbaanhulpbronne was (dit is, indiensneembaarheidseienskappe, loopbaanankers en loopbaanwaardes) om hulle vlakke van loopbaantevredenheid en selfwaargenome indiensneembaarheid te verduidelik nie. Die loopbaankognisies en psigososiale loopbaanhulpbronne het individuele, bepaalde hoofgevolge om te oorweeg ten einde kenniswerkers se loopbaantevredenheid en selfwaargenome indiensneembaarheid te verstaan. Stapsgewyse regressie en hiërargies-moderering regressie-ontleding het gewys dat ouderdom, ras en indiensnemingstatus belangrike oorwegings was wat betref die loopbaantevredenheidsprofiel van kenniswerkers. Ras in die besonder het geblyk belangrik te wees om in aanmerking te neem ooreenkomstig hulle selfwaargenome indiensneembaarheid. Verskille tussen die biografiese groepe het ook aan die hand gedoen dat unieke loopbaanontwikkeling oorweeg moet word in multikulterele, diverse werkskontekste. Die loopbaantevredenheid en indiensneembaarheidsprofiel is saamgestel, gebaseer op die belangrikste insigte wat uit die essensiële, betekenisvolle bevindings bekom is. Loopbaantevredenheid en indiensneembaarheidsteorie is in hierdie navorsing uitgebrei. Aanbevelings vir organisatoriese loopbaanontwikkelingondersteuningspraktyke is gemaak, gebaseer op die voorgestelde profiel vir die professionele kenniswerker. / Maikemisetsomagolo a dinyakisiso e bile go go hlama phrofaele ye e kgotsofatsago mosomo le go thwalega mosomong go basomi ba tsa tsebo go lebeletswe seemo sa dikamano magareng ga dipharologantsi tsa dipalopalo ka ga batho (e lego mengwaga, bong, mohlobo le maemo a mosomo), go kwesisa ka ga mesomo (go tlwaela mosomo le seemo sa menagano ya setshaba ka ga mesomo bjalo ka dilo tseo di tlago peleng), methopo ya bona mosomo mabapi le menagano ya setshaba (dikokwane tsa go kgona go thwalega mesomong, dihlohleletsi tsa go hwetsa mesomo le maitshwaro a mesomong bjalo ka dilo tseo di lekolago mesomo) le go kgotsofatsa ga dinyakwa tsa mesomo le go ipona bjalo ka yo a thwalegago (seo se tlago ka moragonyana goba bjalo ka poelo).

The end goal of the research was to draw conclusions on the relationship dynamics (magnitude and direction) between the constructs for the purpose of proposing organisational career development practices for the knowledge worker. A quantitative cross-sectional research approach was followed and involved a sample of N = 404 knowledge workers registered with South African professional bodies. Descriptive, correlation and multivariate inferential statistics were performed. Supplementary to the canonical correlation analysis, regression and structural equation modelling analysis indicated that the career satisfaction profile has unique influencing factors while the self-perceived employability profile also has its unique influencing factors. Moderated regression analysis showed that individuals’ career cognitions (i.e. levels of career adaptability and psychosocial career preoccupations) were not conditional upon their psychosocial career resources (i.e. employability attributes, career anchors and career values) in explaining their levels of career satisfaction and self-perceived employability. The career cognitions and psychosocial career resources had individually specific main effects to consider in understanding knowledge workers’ career satisfaction and self-perceived employability. Stepwise regression and the hierarchical moderated regression analysis showed that age, race and employment status were important to consider in terms of the career satisfaction profile of knowledge workers. Race seemed especially important to consider in terms of their self-perceived employability. Differences among the biographical groups also suggested unique career development needs to consider in multi-culturally diverse work contexts. The career satisfaction and employability profile was constructed based on the key insights derived from the core significant findings. The research extended career satisfaction and employability theory. Recommendations for organisational career development support practice were made based on the proposed profile for the professional knowledge worker. / Psychology / Ph. D. (Psychology)

Abstracts in English, Afrikaans and Southern Sotho / The purpose of this study was to develop a best practice corporate community involvement disclosures (CCID) framework for JSE-listed organisations in South Africa. An analysis of the literature underscored the need for quality CCID and revealed the paucity of research on this topic. The study adopted a mixed-methods approach employing three research stages. Firstly, an initial CCID framework was constructed on the basis of a content and document analysis of top-performing JSE-listed organisations. Secondly, 30 CCI experts refined and validated the CCID framework through semi-structured interviews. The developed CCID framework comprised 36 specific disclosure items in nine general disclosure categories. Thirdly, the CCID framework was applied to 116 corporate reports, including the integrated reports, sustainability reports and corporate webpages of 20 JSE-listed companies for the years 2015 to 2017. The findings indicated that the sample of JSE-listed organisations disclose some aspects of CCI in their corporate reports. However, there is no consistent reporting framework, and a number of CCID items were under-disclosed according to the CCI expert “best practice” to meet stakeholder expectations. In both the integrated and sustainability reports, general category 2, CCI strategy, and general category 4, CCI projects, were the best-performing categories. General category 8, Evidence of CCI, was one of the best-performing categories disclosed in the sustainability reports and on the corporate webpages. General category 5, Relevant regulatory measures, general category 6, CCI benefits/business value creation, and general category 7, Assurance of CCI reporting, contained no or limited CCID. The development of the CCID framework resonated with stakeholder theory, while the findings on the application of the CCID framework supported the theoretical perspectives of legitimacy theory. In addition to the identified legitimising drivers, the findings suggested that local tensions and expectations are impacting on CCID in South Africa. The findings of this study provide useful insights into CCID practices, guidelines and the quality of CCID. It is unique because it is the first of its kind to develop and apply a CCID framework in South Africa. The findings have a number of implications for stakeholders, corporate managers, regulators and policymakers in South Africa and internationally. / Die doel van hierdie studie was om ’n raamwerk van beste praktykte te ontwikkel vir korporatiewe gemeenskapsbetrokkenheid-openbaarmakings (KGBO) vir JSE-genoteerde organisasies in Suid-Afrika. ʼn Ontleding van die literatuur het die behoefte aan gehalte-KGBO beklemtoon en die gebrek aan navorsing oor hierdie onderwerp aan die lig gebring.

Eerstens is ʼn aanvanklike KGBO-raamwerk op die grondslag van ’n inhoud-en-dokument-ontleding van bes presterende JSE-genoteerde organisasies saamgestel. Tweedens het 30 KGB-kundiges die KGBO-raamwerk deur middel van halfgestruktureerde onderhoude verfyn en geldig verklaar. Die ontwikkelde KGBO-raamwerk het 36 spesifieke openbaarmaking-items in nege algemene openbaarmakingkategorieë bevat. Derdens is die KGBO-raamwerk toegepas op 116 korporatiewe verslae, insluitend die geïntegreerde verslae, volhoubaarheidsverslae en korporatiewe webbladsye van 20 JSE-genoteerde maatskappye vir die jare 2015 tot 2017. Die bevindings het aangetoon dat die monster van JSE-genoteerde organisasies enkele aspekte van KGBO in hul korporatiewe verslae openbaar het. Daar is egter nie ’n konsekwente verslagdoeningsraamwerk nie, en volgens die KGB-bestepraktykkundige is ’n aantal KGBO-items onderverklaar om aan belanghebbers se verwagtinge te voldoen. In sowel die geïntegreerde as volhoubaarheidsverslae was die algemene kategorie 2, KGB-strategie, en algemene kategorie 4, KGB-projekte, die bes presterende kategorieë. Algemene kategorie 8, Bewys van KGB, was een van die bes presterende kategorieë wat in die volhoubaarheidsverslae en op die korporatiewe webbladsye openbaar gemaak is. Algemene kategorie 5, Relevante regulatiewe maatreëls, algemene kategorie 6, KGB-voordele/besigheidswaarde-skepping, en algemene kategorie 7, Gerusstelling van KGB-verslagdoening, het geen of beperkte KGBO bevat. Die ontwikkeling van die KGBO-raamwerk het by die belanghebberteorie aanklank gevind, terwyl die bevindings van die toepassing van die KGBO-raamwerk die teoretiese perspektiewe van die egtheidsteorie gesteun het. Benewens die geïdentifiseerde egtheidsaandrywers het die bevindings daarop gesinspeel dat plaaslike spanning en verwagtinge ’n uitwerking op KGBO in Suid-Afrika het. Die bevindings van hierdie studie verskaf nuttige insigte in KGBO-praktyke, -riglyne en die gehalte van KGBO. Dit is uniek omdat dit die eerste keer is dat ’n KGBO-raamwerk in Suid-Afrika ontwikkel en toegepas word. Die bevindings het ’n aantal implikasies vir belanghebbendes, korporatiewe bestuurders, reguleerders en beleidmakers in Suid-Afrika en internasionaal. / Morero wa thutelo ye e be e le go tšweletša tlhako ya maitokiši a kaonekaone a dikutollo tša seabe sa dikgwebo setšhabeng (CCID) ya mekgatlo ye e lego lenaneong la JSE ka Afrika Borwa.
