    Consumers' motivations to engage with local brands on social media
    (Stellenbosch University, 2024-12) Esterhuyzen, Lisa
    The 'consumer brand engagement' (CBE) concept comprehensively reflects consumers' motives for social media use, particularly digital consumer engagement behaviour. However, despite the growing scholarly interest in addressing 'engagement', disagreement exists regarding the nature of engagement behaviours and the predictive role of consumer motivations. Further, although there is a ‘buy local’ movement whereby consumers are encouraged to support local brands, the role of ethnocentrism in consumers’ decision to engage with local brands on social media has not been examined. To address these gaps in the literature, this study drew from the Uses and Gratifications Theory to examine CBE on social media in a local South African wine brand context and the possible moderating effects of ethnocentrism. A sequential mixed-method research design comprised of a qualitative phase one (focus group discussions) and a quantitative phase two (survey questionnaire) was utilised. The data recorded from phase one was thematically analysed, whereas Partial Least Squares Structural Equation Modelling (PLS-SEM) was employed during phase two. Findings from phase one suggested that the concept of ‘local brand’ is contextual and that although consumers hold positive sentiments towards phrases such as ‘local is lekker’, an overall negative perception of South African product quality persists. Results from phase two revealed that consumer motivations to engage on social media predict consumer online brand-related activities (COBRAs) in varying degrees and that consumer ethnocentrism plays a limited moderating role. Theoretically, this study contributes by refining the model proposed by Buzeta et al. (2020), thus providing insight into the interrelationships that exist between consumers’ motives to engage with local wine brands on social media and their subsequent COBRAs. Managerially, brand managers need to understand that different motivations are associated with different COBRAs and adjust their social media campaigns accordingly.

    Om die evangelie in jou eie taal te sien : ervarings van in- en of uitsluiting van dowe persone in 'n gemeentelike konteks - 'n gevallestudie
    (Stellenbosch : Stellenbosch University, 2023-12-15) Oberholzer, Jan Hendrik; Nell, Ian; Stellenbosch University. Faculty of Theology. Dept. of Practical Theology and Missiology
    AFRIKAANSE OPSOMMING: Kultuurdowe persone, wat hoofsaaklik Gebaretaal, as voorkeurtaal gebruik, beleef soms taalongeregtighede, linguistiese-marginalisering en stigmatisering. Die hoofstroom kerk sluit Kultuurdowe persone soms uit as gevolg hiervan. So word die Blye Boodskap vir Kultuurdowes verbloem. Die rede is, die kerk se taal, se simbole, kultuur, houdings en hul algemene siening oor Dowe persone, is verwyder van die Kultuurdowe Christene sʼn. Kultuurdowe persone word die geleentheid ontneem om hul priesterskap as Christen-gelowiges uit te leef. Die studie het binne die vakgebied Praktiese Teologie plaas gevind en die navorsingsfokus was op gemeentestudies. Die navorsing is kwalitatief, induktief, en sosiaal konstruktivisties van aard en die navorsingsresultate word as ʼn gevallestudie aangeteken. Die navorsingsvraag was, of Dowegelowiges, die ervaring van in-en of uitsluiting binne die Dowe Familiekerk (DFK), in Worcester, binne ʼn gemeentelike konteks ervaar het of nie. Daar is met ʼn aantal Kultuurdowe persone semi-gestruktureerde onderhoude gevoer. Die resultate is tematies ontleed met gebruik van ATLAS. Ti as navorsingsinstrument. In die Dowe Familiekerk (DFK) te Worcester, blyk dit dat Dowe lidmate uitsluiting ten opsigte van besluitnemingsprosesse beleef. Wanneer daar nie Suid-Afrikaanse Gebaretaal (SAGT) tydens gemeentelike byeenkomste gebruik word nie, vind daar taalongeregtigheid plaas. Die navorsingsresultate toon aan dat die Dowe lidmate wel toeganklikheid en ʼn eenheid beleef te midde van ʼn ruim kulturele diversiteit en getuig dat die DFK tog ʼn geestelike tuiste vir hulle is. Die navorsing toon dat die volgende faktore in- en of uitsluiting beïnvloed, naamlik; toeganklikheid, verhoudinge en verandering. Hierdie drie het aanleiding gegee tot gevoelens van of in- en of uitsluiting van Dowe lidmate van die DFK. Die studie dra verder tot akademiese navorsing in Suid Afrika by, in soverre, dat die Dowe Familiekerk ʼn gawe vir die breër kerk is. Die lidmate van die DFK het binne een gemeente, horende-, Dowe-, sowel as meervoudige gestremdhede- en veelrassige lidmate. DFK bestaan ook uit lidmate van ʼn multi--kulturele afkoms.

    Putting choral music to work in the e’Bosch Schools Choir Festival: a descriptive case study
    (Stellenbosch : Stellenbosch University, 2022-04) Reynolds, Brent; Muller, Danell; Stellenbosch University. Faculty of Arts & Social Sciences. Dept. of Music.
    ENGLISH ABSTRACT: The e’Bosch Schools Choir Festival (e’BSCF) is one of the flagship projects of the e’Bosch Heritage Project (e’Bosch). As one of the biggest inter-school gatherings of school children in the greater Stellenbosch municipal area, the e’BSCF seeks to achieve the objectives of e’Bosch through the implementation of a school choir festival. In doing so, choral music is used to serve a purpose beyond its intrinsic aesthetic value and gets ‘put to work’ to the positive transformation of individual and community lives. This study sought to describe how choral music is put to work in the e’BSCF. As the first academic study of the e’BSCF, the study was designed as a qualitative descriptive case study and data was collected by means of semi-structured interviews, a questionnaire, and document analysis. The study took place in three research phases. The first was to understand what it means to put the arts to work in the context of community music, a praxial philosophy of music education, and artistic citizenship. By considering relevant literature in these three fields, a conceptual framework was formed which was used as a set of a priori codes to organise and analyse the data collected. The second phase sought to provide a comprehensive description of the e’BSCF. The third phase explored the relationships between the conceptual framework and the data collected. By inductive reasoning, the initial conceptual framework was adapted and expanded to effectively describe how choral music is put to work in the e’BSCF. Findings suggest that the e’BSCF plays an important role in e’Bosch achieving its objectives. A particular challenge for the e’BSCF is getting as many schools as possible, from all cultural backgrounds, to participate. The e’BSCF is uniquely positioned as it does not have a competitive nature and as such can focus entirely on the process of putting choral music to work instead of a focus on perfecting the musical product. This study opens the door to many possibilities for further research and takes one step in closing the gap between community music research and community music practice.

    A software defined radio based radar system with applications in the detection of wildlife poaching
    (Stellenbosch : Stellenbosch University, 2023-12) Van Zyl, Christiaan; Niesler, Thomas; Stellenbosch University. Faculty of Engineering. Dept. of Electrical and Electronic Engineering.
    ENGLISH ABSTRACT: This thesis presents the development and testing of a low-cost and low-power software-defined r adio ( SDR) b ased r adar p latform f or u se i n anti-poaching applications. A low frequency of 1.1 GHz is specifically selected to investigate the viability of classifying human activity, whilst enabling foliage penetration. A software interface and control tool for the SDR was developed to enable the rapid development and testing of radar techniques, and the collecting and storing of data in the form of I/Q samples. A signal processing pipeline was implemented using the Julia programming language to generate range-Doppler maps from these I/Q samples. Existing non-linear frequency modulated pulse compression waveforms did not yield satisfactory performance due to the low time-bandwidth product regime in which the radar system operates. A pulse compression waveform based on optimised Bézier curves was therefore developed and shown to offer improved performance over existing methods that require a higher time bandwidth product. The best Bézier vertices were determined by a particle swarm optimisation method, which is also presented. A dataset was collected to evaluate the system’s ability to classify targets based on micro-Doppler frequencies. A novel convolutional neural network configuration t hat u ses t emporal D oppler f rames i s p resented a nd s hown to achieve a classification accuracy of 91.6% when testing on a dataset containing a single person. Therefore, it may be concluded that SDR-based radar merits further consideration as a low-cost and low-power approach to the detection of poachers in automated anti-poaching systems.

    Utilising Choice Theory and Reciprocal Teaching to promote the teaching of reading comprehension in the Intermediate Phase (Grades 4 to 6)
    (Stellenbosch - Stellenbosch University, 2023-03) Messina, Mitchell; Le Cordeur, Michael; Robey, Patricia
    In South Africa, learners’ standard of reading in the Intermediate Phase (Grades 4 to 6) is cause for considerable concern. The 2016-PIRLS findings have provided overwhelming evidence that South African Grade 4 learners struggle with reading comprehension (Pretorius & Klapwijk, 2016). In addition, key findings of the same study showed that 78% of Grade 4 learners in South Africa do not have basic reading skills by the end of the Grade 4 school year. Therefore, the reading comprehension standard in the Intermediate Phase (Grades 4 to 6) of South Africa is in dire need of reconsideration. This study investigated how Choice Theory, as an explanation of human behaviour, can provide a foundation to enhance the teaching of Reciprocal Teaching reading comprehension strategies. The study highlighted that Choice Theory in education provides an intrinsic model of teaching that could be utilised to promote the explicit teaching of the four reading comprehension strategies of Reciprocal Teaching. This study was a real effort to shift the focus from the learners to the teachers who have not been trained effectively to teach Reciprocal Teaching reading comprehension strategies explicitly. The study was based on the theoretical framework of Social Constructivism, Choice Theory, and Reciprocal Teaching as underpinning theories for the development of the teaching of reading comprehension. A qualitative research approach was adopted to make sense of participants’ experience of Choice Theory and Reciprocal Teaching. For the purpose of this qualitative research, a single-case study was chosen as the research design to obtain in-depth information from the participants. Data were collected through classroom observations, semi-structured interviews, focus group meetings and reflective journals of teachers. The data from the observations and interviews were used triangulated to confirm or disconfirm findings and helped to control or correct the subjective bias of the individual. The researcher used ATLAS.ti, a CAQDAS software programme, to manage and manipulate the data.
