Potential barriers to international exchange semesters at Stellenbosch University
No full textThesis (MPhil)--Stellenbosch University, 2015.ENGLISH SUMMARY : Higher education is challenged by the changing climate created by globalisation and the phenomenon of internationalisation. Internationalisation of higher education provides a platform for institutions to engage with counterparts across the world in a manner that would enhance the quality of all aspects of the institution, but also poses a number of challenges to institutions and higher education systems. The literature review of the study sketches the background to the study and analyses some of the above-mentioned opportunities and challenges.
The study researched one aspect of internationalisation, namely the mobility of undergraduate students. The mobility of students can take place through an array of activities that includes summer school programmes, internships, or tailored short programmes. This study focuses on one type of mobility, namely an international exchange semester.
The study stemmed from the actual problem at Stellenbosch University where a major imbalance exists in the number of students received from partner universities and of Stellenbosch students taking part in a semester at the partner university.
The rationale and practice of international exchange semesters in four Faculties were analysed on multiple levels by means of a case study design. The four case studies were concluded in the Faculty of Arts and Social Sciences, the Faculty of Science, the Faculty of AgriSciences and the Faculty of Economic and Management Sciences, and within these Faculties the investigation was restricted to general-formative programmes. Data were collected and analysed at four levels of each Faculty, namely the climate that is created through Faculty strategy, the views and perspectives of students in their final and pre-final year, the view and perspectives of programme coordinators, and finally, the views on a managerial level by means of the inputs of deputy deans.
Each of the case studies reveals specific issues and opportunities for international exchange semesters within the particular Faculty, yet, the comparative perspectives reveal that the major barriers to student mobility are consistent across faculties, and that particularly the type of information available, the applicability of that information within the particular academic environment and financial aspects are consistently identified by students in all four Faculties. The barriers identified by staff, both on departmental and management level, resonate with the barriers identified by students, but further illustrate more specific organisational and pedagogical challenges linked to the implementation of international exchange semesters.
The study not only makes a contribution to a deeper understanding of existing challenges pertaining to international mobility by means of an exchange semester but it also makes specific recommendations to address these challenges and poses alternatives to existing practices.AFRIKAANSE OPSOMMING : Hoër onderwys word uitgedaag deur die veranderende omgewing as gevolg van globalisering en deur die verskynsel van internasionalisering. Internasionalisering van hoër onderwys bied ’n platform vir interaksie tussen instellings en hul eweknieë in ander wêrelddele op ’n wyse wat die gehalte van alle aspekte van die instellings kan bevorder. Internasionalisering is egter ook ’n verskynsel wat ’n bedreiging en ’n uitdaging vir instellings en hoëronderwysstelsels inhou. Die literatuurstudie van hierdie studie skets die agtergrond tot die studie en ontleed van hierdie geleenthede en uitdagings.
Die studie het een aspek van internasionalisering, naamlik die mobiliteit van voorgraadse studente, ondersoek. Die mobiliteit van studente geskied deur ’n verskeidenheid aktiwiteite wat somerskole, internskappe en taalkursusse insluit. Die studie fokus op een aktiwiteit, naamlik internasionale uitruilsemesters.
Die studie het gepruit uit ’n voortslepende uitdaging by die Universiteit van Stellenbosch (US) waar die aantal inkomende uitruilstudente van vennoot-instansies die aantal US studente wat aan uitruilsemesters deelneem, ver oorskry.
Die rasionaal en uitvoering van internasionale uitruilsemesters in vier fakulteite is deur middel van ’n gevallestudie-ontwerp op verskeie vlakke ontleed om ʼn omvattende begrip te ontwikkel. Die vier gevallestudies is in die konteks van die Fakulteit Lettere en Sosiale Wetenskappe, Fakulteit Agriwetenskappe, Fakulteit Natuurwetenskappe en Fakulteit Ekonomiese en Bestuurswetenskappe uitgevoer, en in die studie van hierdie vier fakulteite is die konteks verder tot algemene vormende programme beperk. Data is ingewin en ontleed op vier vlakke in elke fakulteit, naamlik die platform wat geskep word deur die strategie van die fakulteit, die oortuigings en perspektiewe van studente in hulle finale en voor-finale jaar, die perspektiewe en insig van programkoördineerders, en laastens die perspektief op bestuursvlak deur middel van onderhoude met adjunkdekane.
Elke gevallestudie onthul spesifieke kwessies ten opsigte van en geleenthede vir internasionale uitruilsemesters binne die betrokke fakulteit, maar die vergelykende perspektiewe dui aan dat die grootste struikelblokke vir studente mobiliteit deurlopend dieselfde is tussen die vier fakulteite. Die studie toon aan dat die beskikbaarheid van die tipe inligting, die toepaslikheid van daardie inligting op ‘n student se spesifieke situasie (program) en finansiële aspekte in al vier fakulteite deur studente gekies is. Die struikelblokke wat deur personeel, beide op departementele en bestuursvlak, uitgewys is vind aanklank by die struikelblokke wat deur studente aangedui is, maar illustreer ook verdere uitdagings ten opsigte van organisatoriese aspekte en pedagogiese uitdagings wat verband hou met die implementering van internasionale uitruilsemesters.
Die studie maak nie net ‘n bydrae in terme van ‘n dieper verstaan van die bestaande uitdagings ten opsigte van internasionale studente mobiliteit deur middel van ‘n uitruilsemester nie, maar maak ook voorstelle oor hoe om hierdie uitdagings aan te spreek en stel alternatiewe voor vir die bestaande praktyke.Master
Internationally linked authors in Uganda, East Africa : an example of author-level bibliometrics for a developing country
No full textCITATION: Boshoff, N., Basaza-Ejiri, H. A. D. & Tise, E. R. 2018. Internationally linked authors in Uganda, East Africa : an example of author-level bibliometrics for a developing country. In STI 2018 Conference Proceedings, 23rd International Conference on Science and Technology Indicators, 12-14 September 2018, Leiden, Netherlands.The original publication is available at http://sti2018.cwts.nl/proceedingsIn developing countries, researchers with strong international links potentially act as a double-edge sword. On the one hand, local researchers with international links could strengthen the research base of an institution or country while, on the other hand, they could leave the research base vulnerable should they migrate. The study identified internationally linked authors in Uganda, East Africa, by applying individual-level bibliometrics to a dataset of 3,948 Ugandan authors from the Web of Science, for the period 2011–2015. The focus was on four overlapping groups of internationally linked authors: (1) Ugandan authors with an international co-author, (2) Uganda authors with a joint international affiliation, (3) Ugandan authors affiliated with an international organisation that has a local address, and (4) Ugandan authors affiliated with an international research partnership. The study showed that without the identified forms of international linkages, the Ugandan scholarly workforce would reduce to 14% of its current size. Moreover, 74% of Ugandan authors without any international links had co-authored articles with Ugandan authors who are linked internationally. Although the extent of both international and national mobility associated with internationally linked authors seem low, benchmarking against comparative figures for other countries in sub-Saharan Africa is required.http://sti2018.cwts.nl/proceedingsPublisher's versio
X-Ray Micro Tomography of Water Absorption by Superabsorbent Polymers in Mortar
No full textSuperabsorbent Polymers (SAP) have been recently subject of investigation as smart admixtures for cement-based materials. The properties of these polymers enable their use for internal curing, increasing freeze/thaw resistance, boosting autogenous self-healing and providing a crack self-sealing effect in cementitious composites. Except for the earliest application, the functioning of these beneficial effects invloves the absorption by the polymers of ingress water in the hardened cementitious matrix and later release, as well as their capacity to complete multiple absorption/desorption cycles. In this work, the absorption of water in mortar with superabsorbent polymers is monitored during the first 60 min of absorption through micro-CT. The experimental series included the presence of cracks. The registration and differentiation of sub-minute (18 s) scans enabled the individuation of bulk water content distribution in the mortar with a resolution of 55 μm. The swollen volume of SAP could also be quantified and studied in time. The results point out that although embedded SAP absorb water from the matrix, this absorption is slow and reduced with respect to water absorption during mixing for the used SAP. Same effect is observed for SAP in the cracks.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen

STATIONARITY TESTS IN GEOGRAPHIC MARKETS: AN APPLICATION TO SOUTH AFRICAN MILK MARKETS
No full textThe paper focuses on the delineation of geographic markets in competition analysis, investigating the use of tests of price co-movement in the market definition exercise. To this end, the first part is devoted to a conceptual framework for market definition (adopted from Haldrup (2003 )). Thereafter, a variety of price tests are explored that can be applied within the quantitative part of the framework. Similar to Forni (2004 ), the paper emphasizes the use of stationarity tests (that is, tests for the existence of unit roots) - illustrating their application to a recent competition investigation in South Africa.

A literary-exegetical- and social-scientific analysis of the book of Jonah : an exposition of its ancient social values
No full textThesis (DLitt)--University of Pretoria, 2016.By approaching the book of Jonah historical-critically, it has been indicated that the book of Jonah
likely dates to the Persian Period (more neutrally the post-exilic period), is a parody on the prophetic
traditions, and has a unified structure. It has been proposed by some that the book of Jonah was written
for the Yehudite elite, as a meant, by the author, for his audience to reflect critically on themselves.
When a literary-exegetical analysis was conducted of the book of Jonah, it was indicated that the
author of the book employed various literary and stylistic techniques that contributes to the unified
structure of the book of Jonah. It has also been indicated that all the prayers in the book is poetry, and
serves to pause the narration, and are employed to emphasise their content. The author also inverts the
typical Ancient Near Eastern values in his characterisation of the role players to thwart the reader's
typical expectations of each. The application of social-scientific criticism then supports the theory that
the book of Jonah is indeed a parody, and that its main theme in the book of Jonah relates to the
compassion and mercy of Yahweh/God which outweighs his desire to destroy the inhabitants of
Nineveh and their animals, and appears to be conditional, as repentence is a requirement.Ancient LanguagesDLittUnrestricte
CIGARETTE DEMAND IN SOUTH AFRICA OVER 1996-2006: THE ROLE OF PRICE, INCOME AND HEALTH AWARENESS
No full textThe study seeks to re-investigate the role of price, income and health awareness in the evolution of South African cigarette demand over the period 1996 to 2006. At first glance, rising cigarette prices appear to have played an important role in reducing cigarette consumption over the sample period, especially during the late 90s. But how dependent is the impact of price increases on general economic conditions and overall health awareness among smokers? Health awareness, in particular, has not received sufficient attention in the South African context, due to a lack of data. Previous estimates of price and income elasticities of cigarette demand are based on long annual time series data, which do not allow for changes in underlying tastes and preferences. The paper attempts to disentangle the forces of price, income, health awareness and policy intervention using a quarterly data set. In addition, the study also cautions against the upward bias in estimates derived from formal cigarette sales data - in the light of increasing illicit cigarette volumes in South Africa.
