The practice of promoting food to children via advergames is a highly topical issue which attracts much concern due to the low nutritional value of the promoted foods. This thesis examines the effects of customised food advergames on children’s affective, cognitive and conative responses. It also investigates the role persuasion knowledge and prior brand usage have in children’s interaction with advergames. In particular, whether children’s persuasion knowledge acts as a barrier to those responses. This research is situated within the domains of marketing communications, consumer behaviour and consumer socialisation. It adopts an affect transfer theory, the Dual Mediation Hypothesis (DMH), to explain the transfer of affect from an advergame to children’s responses. Three versions of the same advergame were designed for the purpose of this thesis with different levels of customisation (i.e. control, low and high experimental conditions). An experiment among younger (5-7 year olds) and older (11¬12 year olds) children reveals that customisation in advergames has a detrimental effect on children’s affective, cognitive and conative responses. It was the control condition, without customisation options, that rendered a positive impact on brand attitudes and preferences relative to the other two experimental conditions. Persuasion knowledge does not influence children’s affective, cognitive or conative responses. This implies that children’s understanding of the persuasive intent of an advergame does not act as a barrier against its effects. Age had a significant role on children’s attitudes towards the advergame, but not on their other responses to it. Finally, prior brand usage has a positive impact on children’s responses apart from on advergame attitudes. This thesis has implications to policy and practice. It is evident that children from two distinct age and cognitive developmental groups cannot protect themselves from advergames’ effects. Therefore, regulators should broaden the scope of concern to older and younger children alike.

Prior entry refers to the notion that attended stimuli are perceived sooner than unattended stimuli due to a speed up in sensory processing. The century long debate regarding the prior entry phenomenon’s existence has always been grounded in the degree to which the methods applied to the problem allow for cognitive response bias. This thesis continues that trend by applying the synchrony comparison judgment method to the problem of audiovisual prior entry. Experiment 1 put this method into context with two other common psychophysical methods – the temporal order judgment and the synchrony judgment – that have been applied to the prior entry problem. The results of this experiment indicated that the temporal order judgment method was out of step with the other two methods in terms of the parameter estimates typically used to evaluate prior entry. Experiment 2 evaluated and confirmed that a specific response bias helps explain the difference in parameter estimates between the temporal order judgment method and the other two. Experiment 3 evaluated the precision of the synchrony comparison judgment method. The results indicated that the method was precise enough to detect potentially small prior entry effect sizes, and that it afforded the ability to detect those participants with points of subjective synchrony that deviate substantially from zero. Finally, Experiment 4 applied the synchrony comparison judgment method to a prior entry scenario. A prior entry effect was not realized. Overall, this thesis highlights the drawbacks of all previous methods used to evaluate audiovisual perception, including prior entry, and validates the use of the synchrony comparison judgment. Further, due to the resistance of this method to response bias, this result now stands as the most convincing evidence yet against the prior entry phenomenon.

The advent of the Internet, the influx of technology comparison shopping, and the evolvement of channels have increased the knowledge base of the consumer to the point where some scholars claim the multichannel consumer has more knowledge and control than the salesperson. Selling to a customer who has the control is a challenge for retailers and their sales forces. The purpose of this research is to examine the underlying decision process of the multichannel consumer and the impact of the retail salesperson. This present study tests a conceptual model that suggests multichannel consumers' perceptions of information asymmetry lead to perceived control and purchase intention. Based upon the model, the salesperson's new role is to motivate purchase intention by using adaptive selling to affect the consumer's perception of information asymmetry and perceived control. Using a scenario-based methodology tested with a sample of 307 multichannel consumers, the current investigation examined the impact of: (1) information asymmetry on the consumer's perceived control, (2) perceived control on purchase intention, (3) perceived control as a mediator between information asymmetry and purchase intention, (4) adaptive selling behavior on the consumer's perception of information asymmetry, and (5) adaptive selling behavior on the consumer's purchase intention. The findings revealed that if the multichannel consumer perceives an advantaged information asymmetry then perceived control and purchase intention will be impacted. Adaptive selling behavior affects the consumer's perceptions of information asymmetry but not perceived control. These findings can be used to help managers devise techniques to support the salesperson's ability to secure the sale with the multichannel consumer.

The elevated CO2 levels, elevated temperature, and lower blood pH that may occur during exercise should enhance O2 delivery to the exercising muscles. It was hypothesized that performance of prior exercise (PE) would result in a faster VO2 response, as well as a reduced slow component contribution, in subsequent exercise bouts. Five women (21 ± 1 yr) and 10 men (23 ± 2 yr) performed nine 6-min bouts of heavy intensity cycle ergometer exercise (i.e., above the ventilatory threshold, individually determined by an incremental test). Three bouts were performed without prior heavy exercise (noPE), three were performed 6 min after a 6-min bout of heavy intensity arm cranking (PEA), and three were performed 6 min after a 6-min bout of heavy intensity cycle ergometer exercise (PEL). Breath-by-breath VO2 data from each of the three sets of three tests were combined and fitted to a two-component model, which ignores the cardiodynamic phase. The primary and slow component amplitudes were truncated to reflect actual increases in VO2 in each phase. The effects of PE on the time constant of the primary component were inconsistent. As hypothesized, the amplitude of the slow component was reduced by PE (noPE vs PEA vs. PEL: 25% > 16% < 14%; p < .05). It is concluded that heavy intensity PE affects characteristics of the VO2 profile in a subsequent bout of heavy intensity leg exercise.

In the wake of diversifying economy through science and technology, the government of Botswana is particularly inclined to Intellectual Property Rights (IPR) and Indigenous Knowledge Systems (IKS). IPR in its nature of advocating exclusive rights by the creator comes into direct conflict with the practice and understanding of IKS as community property, and a shared resource. To date, there is very little research work that explores policymakers’ knowledge about IPR and IKS in developing countries. Botswana, a developing country is yet to benefit from this type of research. This research investigated policymakers’ knowledge and practices of IPR on IKS in Botswana. The focus was on policymakers’ knowledge and practices, interaction with policy, and how their actions could be understood and explained. The study was conducted in four government departments, and one non-governmental organisation. Semi-structured interviews and document analysis were used to collect data. The findings of the study show that there is general lack of understanding about IPR in the public domain. Policymakers nonetheless know quite substantially about IPR and very little about IKS. This position puts indigenous knowledge on the periphery, and on the brink of being swallowed by other technologies. Moreover, the study uncovered evidence that the IPR and IKS activities are fragmented and policymakers treat each other with a great deal of suspicion and misunderstanding, hence affecting successful implementation of policy and projects particularly between two units in the study- the ministry of Communication, Science and Technology and the ministry of Trade and Industry. The study concludes by arguing that policymakers still require a great deal of assistance to really make sense of their practice. A lot of teaching and learning about policy is necessary to encourage broader participation in science policymaking in the context of a developing country like Botswana. / Dissertation (MEd (Science and Technology Education))--University of Pretoria, 2008. / Curriculum Studies / unrestricted

Thesis (Ph. D. (Language Education)) -- University of Limpopo, 2016 / This study investigates the challenges for an implementation of Recognition of Prior Learning (RPL) at three FET Colleges in Limpopo Province. The implementation of RPL in the South African education system is seen as an essential tool to drive transformation in FET Colleges. RPL was designed to play a unique role in the provision of the higher level skills required to support the socio-economic growth and development of the nation. With all these good intentions, RPL is virtually non-existent in our public FET Colleges. This is a qualitative case study in which both exploratory and descriptive designs were used. Data was collected from observations, documents, interviews and questionnaires from the learners and educators. Twenty one learners and seven educators were interviewed. Questionnaires were distributed to nine educators. The purposive sampling method was used. The significant findings are that there are no RPL policy guidelines, no quality management systems, a shortage of accredited staff and equipment prescribed for RPL, and lack of management and leadership commitment to implementation of RPL. This study therefore recommends the urgent implementation of RPL in FET colleges to promote access and to urgently address the needed skills for the nation. The research also recommends an effective model on quality assurance which appears to be compromised in colleges. The research also recommends effective and efficient training of educators, as this study revealed that the educators have low academic qualifications. While the Ministerial Task Team on RPL recommends a holistic approach to implementation, this research recommends an effective training model for the FET educators to implement RPL.

The CEO of a large listed firm is often under public scrutiny due to listing requirements of stock exchanges of the respective country as well as pressures from stakeholders. Of these stakeholders, shareholders are mostly interested in the firm performance as it relates to their investment to determine if their investment is still worthwhile as well as to determine its returns. A CEO has the duty of ensuring that a firm meets its set targets and the responsibility of having to account for any deviations from these targets. In a firm with sound corporate governance measures, any underperformance experienced by the firm should result in the CEO being replaced and when targets met, the CEO being rewarded. However this is not always the case and this study considers the key determinants of CEO turnover as it later aims to determine what these key determinants are in South African JSE-listed firms as well as the correlation with CEO turnover. This study examines the relationship between ownership structure and board characteristics on CEO-firm performance sensitivity. The population for this study was 60 companies listed on the Johannesburg Stock Exchange. The period covered for this study runs over 5 years from 2013 to 2017. This period was chosen mainly because data for some companies was missing for the period beyond 2017. Thus, excluding companies that had no data for the period beyond 2017 could have reduced the sample further and would have made the analysis less meaningful. The study reports three important findings. The first is that CEO turnover is insensitive to firm performance, irrespective of whether it is an accounting-based firm performance (i.e CEO turnover vs EBIT/Assets ratio) or market-based measure of firm performance (lagged stock returns, 18, 24, and 36 months respectively). Second, the findings of this study show that CEO age and institutional ownership are inversely related to CEO turnover. In addition, board size becomes a significant determinant of CEO turnover when the model in includes returns lagged over 36 months or when the EBIT/Assets ratio is part of the Model (see models 7 and 8), although this is only at 10% level of significance. Third, board insiders and firm size are found to be unrelated to CEO turnover.

In this dissertation I explore how the international law principle of free, prior and informed consent (FPIC) can enhance public participation, to promote environmental justice for communities affected by environmental decision-making in the mining sector in South Africa. Public participation required in terms of the mining sector environmental regulatory framework in South Africa is underscored by a requirement to ‘consult’. In chapter one, I describe how the requirement to consult differs from a requirement to secure consent in terms of FPIC. I describe public participation (i.e. consultation) requirements related to applications for rights, permits, licences and authorisations that must be in place prior to commencement of mining operations. I argue that where the level of public participation requires mere consultation, it can easily amount to a regulatory tick-box exercise given that the views of mining-affected communities can be manipulated or overlooked, with mining developments proceeding despite devastating effects on communities. In chapter two I describe how FPIC has become part of the regulatory framework governing mining activities through the court’s purposive interpretation of the Interim Protection of Informal Land Rights Act 31 of 1996 (IPILRA) in Baleni and Others v Minister of Mineral Resources and Others and Maledu and Others v Itereleng Bakgatla Mineral Resources (Pty) Limited and Another. In chapter three, I engage with scholarly literature on FPIC to analyse why and how environmental justice should and can be enhanced by embedding FPIC into legislative public participation requirements. I argue that FPIC, which now forms part of South Africa’s law through the IPILRA, should be a prominent feature in public participation processes for mining-affected communities generally, and not only for informal land right holders. / Mini Dissertation (LLM)--University of Pretoria, 2021. / Public Law / LLM / Unrestricted

This research examines the mediation effects of prior experience, access to finance, government regulation, and workforce skills on entrepreneurial gender and corporate innovation in China. The aim is to study the factors that influence innovation decisions of women entrepreneurs and to promote corporate innovation in women-owned enterprises in developing countries like China. The data of this research comes from China Enterprise Survey conducted by World Bank in 2012. The findings revealed that prior experience, government regulation, and workforce skills have significant individual mediation effect on the relationship between entrepreneurial gender and corporate innovation. Also, prior experience, access to finance, government regulation, and workforce skills together played a significant overall mediating effect on corporate innovation in women-owned enterprises. The results of this study will provide important insights to women owners of enterprises, policy makers, and researchers to further understand the influence of prior experience, access to finance, government regulations, and workforce skills on corporate innovation in China and other emerging countries.
