Text in English / In recent years, there have been tremendous advances in information technology, robotics, communication technology, nanotechnology, and artificial intelligence, resulting in the merging of physical, digital, and biological worlds that have come to be known as the "fourth industrial revolution”. In this context, the present study engages such technology in the green economy and to tackle the techno-economic environmental impact assessments challenges associated with floating solar system applications in the agricultural sector of South Africa. In response, this exploratory study aimed to examine the development of a Geographical Information System (GIS)-based support platform for Environmental Impact Assessment (EIA) and due-diligence analyses for future planned agricultural floating solar systems, especially with the goal to address the vast differences between the environmental impacts for land-based and water-based photovoltaic energy systems. A research gap was identified in the planning processes for implementing floating solar systems in South Africa’s agricultural sector. This inspired the development of a novel GIS-based modelling tool to assist with floating solar system type energy infrastructure planning in the renewable energy discourse. In this context, there are significant challenges and future research avenues for technical and environmental performance modelling in the new sustainable energy transformation. The present dissertation and geographical research ventured into the conceptualisation, designing and development of a software GIS-based decision support tool to assist environmental impact practitioners, project owners and landscape architects to perform environmental scoping and environmental due-diligence analysis for planned floating solar systems in the local agricultural sector. In terms of the aims and objectives of the research, this project aims at the design and development of a dedicated GIS toolset to determine the environmental feasibility around the use of floating solar systems in agricultural applications in South Africa. In this context, the research objectives of this study included the use of computational modelling and simulation techniques to theoretically determine the energy yield predictions and computing environmental impacts/offsets for future planned agricultural floating solar systems in South Africa. The toolset succeeded in determining these aspects in applications where floating solar systems would substitute Eskom grid power. The study succeeded in developing a digital GIS-based computer simulation model for floating solar systems capable of (a) predicting the anticipated energy yield, (b) calculating the environmental offsets achieved by substituting coal-fired generation by floating solar panels, (c) determining the environmental impact and land-use preservation benefits of any floating solar system, and (d) relating these metrics to water-energy-land-food (WELF) nexus parameters suitable for user project viability analysis and decision support. The research project has demonstrated how the proposed GIS toolset supports the body of geographical knowledge in the fields of Energy and Environmental Geography. The new toolset, called EIAcloudGIS, was developed to assist in solving challenges around energy and environmental sustainability analysis when planning new floating solar installations on farms in South Africa. Experiments conducted during the research showed how the geographical study in general, and the toolset in particular, succeeded in solving a real-world problem. Through the formulation and development of GIS-based computer simulation models embedded into GIS layers, this new tool practically supports the National Environmental Management Act (NEMA Act No. 107 of 1998), and in particular, associated EIA processes. The tool also simplifies and semi-automates certain aspects of environmental impact analysis processes for newly envisioned and planned floating solar installations in South Africa. / Geography / M.Sc.

La Quarta rivoluzione industriale e l’evoluzione tecnologica in atto stanno innescando significativi cambiamenti a livello culturale, sociale ed economico. Le rapide trasformazioni del mondo del lavoro portano in luce l’esigenza di coinvolgere i principali soggetti responsabili di guidare il cambiamento organizzativo e professionale all’interno di un percorso di ricerca partecipata e collaborativa, capace di esplicitare e descrivere diversi modi di affrontare le esperienze connesse ai mutamenti in corso. All’interno di questo contesto, il lavoro di tesi intende contribuire a delineare la nuova cultura del lavoro che sta emergendo da alcune pratiche innovative, presenti all’interno del nuovo ecosistema educativo e formativo. La ricerca scientifica, iniziata nel settembre 2019 e conclusa nel settembre 2020, si articola in quattro domande: Come sta cambiando il contesto nel quale viviamo e lavoriamo? Come si sta trasformando la cultura del lavoro? Quali Driver ne facilitano l’apprendimento? Gli elementi della cultura del lavoro sono utili anche alla luce di una nuova trasformazione radicale e improvvisa? Le risposte intendono fornire alcuni spunti di riflessione e un primo orientamento pratico per tutti coloro i quali sono coinvolti in prima persona nella costruzione di nuove soluzioni per l’apprendimento, volte a trasferire valore ai cittadini e ai lavoratori di domani. / The Fourth Industrial Revolution and the technological evolution in place are originating significant changes in culture, society and economy. Rapid transformations in the world of work revealed the need of involving the main subjects in charge of driving both organizational and professional change toward an engaging and collaborative research path, able to make clear and describe different ways to face the experiences connected with the undergoing changes. Within this context, the thesis aims at contributing in outlining the new work culture emerging from some innovative practices, present in the new educational and training ecosystem. The scientific research, started in December 2019 and concluded in September 2020, is articulated in four questions: How is the context in which we live and work changing? How is the work culture undergoing transformations? Which Drivers do facilitate its understanding? Are the elements of the work culture useful also in the light of a new radical and unexpected transformation? The answers intend to provide some points for reflection and a first practical guidance for all those who are directly involved in the creation of new learning solutions, aimed at transferring value to citizens and workers of tomorrow.

The fourth industrial revolution and twenty-first century employability development has emerged on education and political agendas as a priority all over the world. Researchers have suggested and investigated more innovative learning experiences using technology as part of a blended learning approach. Restructuring current programmes to include skills development has the potential to equip students with the skills needed for employment. The development of blended learning approaches is an expanding field in both developing and developed countries. Yet, the skills graduates display and employers’ dissatisfaction is a concern. Limited research has been conducted on the use of blended learning to enhance employability development in formal learning environments. Most of the available research relies on employer perceptions, with little data available on the knowledge, skills and values graduates actually possess or on the impact this has on employability outcomes. This study aims to address this gap by focussing on managing the quality of employability development in higher education using blended learning. The study was aimed at gaining insight into the perceptions, understanding, concerns and experiences of institutional managers, tutors, graduates and students in their real world when using blended learning to enhance graduateness. This aim made the qualitative research method a suitable match. This thesis reports on the resulting comparative study between a South African and an American institution using different blended learning approaches to compare different cases for similarities and variations. The South African higher education sector’s fitness for purpose and pursuit of benchmarking against international standards of academic quality, knowledge and expertise calls for redress and reform of teaching-learning. In the fourth industrial revolution with a 21st century knowledge economy, driven from a macro- meso- and microlevel perspective, higher education in South Africa has the potential to provide a workforce that is socially and economically viable and more inclusive. The thesis concludes with a model to support employability development in blended learning environments. / Uphuhliso lwezakhono nokuqesheka ngenkulungwane yamashumi amabini nanye,zivele kwii-ajenda yezemfundo kunye nezopolitiko njengeziqaqambileyo kwihlabathi jikelele.

English, Afrikaans and Northern Sotho summaries / Die algemene doel van hierdie navorsing was om ’n loopbaantevredenheids- en indiensneembaarheidsprofiel vir kenniswerkers saam te stel, gebaseer op die verhoudingsdinamika tussen individue se biografiese eienskappe (ouderdom, ras en indiensnemingstatus), loopbaankognisies (loopbaanaanpasbaarheid en psigososiale loopbaanpreokkupasies as voorgangers), hulle psigososiale loopbaanhulpbronne (indiensneembaarheidskenmerke, loopbaanankers en loopbaanwaardes as moderators) en hulle loopbaantevredenheid en selfwaargenome indiensneembaarheid (gevolge of uitkomste). 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)
