- Description: This thesis reports on the syntheses and characterizationof symmetrical (charged and neutral), asymmetrical (neutral) metallophthalocyanines (MPcs) and subphthalocyanines (SubPcs). The charged and neutral Pcs were physically doped onto silica nanoparticles (SiNPs). The asymmetrical MPc was also chemically linked to SiNPs. Spectroscopic and microscopic techniques were used to confirm the formation of SiNPs-MPc conjugates. The photophysics and photochemistry of the MPcs were assessed when alone and in conjugates (with SiNPs). The studies showed no significant changes in fluorescence quantum yields (ϕF) and fluorescence lifetimes (ϕF) of MPcs following doping except for 2-SiNPs (2 = Zn tetraaminophenoxyphthalocyanines) and 6-SiNPs (doped) (6 = Zn tris[(4-(pyridine-4-ylthio)2-thio-4-methylthiazol-5yl) acetic acid phthalocyanine) where there was a decrease in the ϕF value. Also for 1-SiNPs (1 = unsubstituted ZnPc) there was an elongation in τF which could be due to the protection offered by SiNPs. Both charged/neutral MPcs displayed high triplet quantum yields (ϕT) and singlet quantum yields (ϕΔ) following doping except for 2-SiNPs where there was a decrease in the latter. For 1-SiNPs there was an increase in ϕT but a decrease inϕΔ .There wasa decrease in ϕT and an increase in ϕΔfor4-SiNPs (4 = Zn tetrasulfophenoxyphthalocyanine), the decrease in ϕT could be due to the orientation of theMPc in SiNPs. An increase in both ϕT and ϕΔ for 6-SiNPs (linked) compared to 6-SiNPs (doped) was observed. Complex 5 (5 = Zn tetra-kis-(dodecylmercapto) phthalocyanine) showed a low ϕΔ value.

- Description: It has become imperative for companies in the motor industry to study and understand the notion of brand loyalty due to the many inherent advantages that it offers. Although existing literature provides extensive information on brand loyalty, the concept of brand loyalty is not constant across all industries. Factors such as age and culture also alter the effects of brand loyalty and the degree of brand loyalty generated within a consumer. Taking these variables into account, this study sets out to establish if age and culture have an effect on brand loyalty in the South African motor industry. The method in which motor companies emit marketing signals are also explored to establish if the emitted marketing signals are able to assist in the generation of brand loyalty. A South African real estate agent group agreed to participate in the research and became the sample population for the study. 190 successfully completed questionnaires were obtained in the data collection process and data with a Cronbach Alpha Coefficient (α) of 0.7662 proved that the data had satisfactory reliability. The data was processed and analysed in the statistical analysis program Stata. The study discovered that marketing signals don't assist in the generation of brand loyalty in the South African motor industry. It is suggested that it is more plausible that marketing signals can assist to maintain brand loyalty, rather than to generate brand loyalty. The study also discovered that culture does not have an effect on brand loyalty in the South African motor industry. However, after considering that the cultural distribution of the sample was significantly skewed, the sample is regarded as an unreliable test of the effect of culture on brand loyalty. The study also discovered that age doesn't have an effect brand loyalty in the South African motor industry. The researcher noted that the previously cognitively strenuous process of obtaining information has become more simplified by the internet and could potentially have reduced the generating of brand loyalty among older consumers. A final test was conducted to ascertain if relationships exist between the four stages of loyalty. The study suggested that all four loyalty stages are connected which confirms that brand loyalty is generated by both attitudinal and behavioural dimensions.

- Description: A significant interest in school educational leadership has developed over the past two decades, whereby effective leadership is required in a continually changing educational environment. This study is a historical analysis of leadership styles of headmasters at Kingswood College in Grahamstown (Eastern Cape, South Africa) from 1993 to 2017. The aim is to identify leadership style(s) of headmasters using the Full Range Leadership (FRL) model as a guiding framework; to describe and interpret these style(s) in relation to the headmaster’s tenure; and to compare the headmasters’ leadership styles, noting key similarities and differences. The research method consists of interviews and a historical archival analysis. The researcher’s expectation is that headmasters will elicit a transformational leadership approach. Key findings were somewhat consistent with this hypothesis, as headmasters exhibit a general trend towards transformational leadership; although each headmaster identifies with a unique facet of transformational leadership, together with relevant supporting leadership style(s) that emerged from the data. Upon comparing headmasters, their primary leadership styles were as follows: Wilkinson identified with transactional, transformational and servant leadership; Hawke showed evidence of a transformational servant leader; Arguile elicited transformational and principle-based leadership; and Trafford depicted transformational and participative leadership. The researcher found that multiple factors in an ever-changing educational environment promoted the need for transformational leadership. The relationship between business management and educational leadership emerges as a key reflection, thus further research is required in this regard.

- Description: The objective of the study is to examine discourses of gender and dimensions of social difference implicated in female sex workers’ (FSWs) justifications of, and resistances to, intimate partner violence (IPV). Individual narrative interviews were conducted with FSWs (n=11) who were affiliated with the Sex Workers Education and Advocacy Taskforce (SWEAT). The participants were mostly women of colour (n=10), with a low socio-economic status, and between 31 and 51 years of age. Intersectionality and features of Foucauldian discourse analysis, as described by Parker (1992), informed the analysis of the interview data. In personal interviews, participants interrogated aspects of their own and their partners’ lives that they viewed as playing a significant role in the aetiology and experience of IPV. They drew on a discourse of violent black masculinity, developmental discourses, and patriarchal ideology to justify and resist their partners’ violent behaviour. They also positioned themselves and their ‘spoiled’ identities as playing a role in the experience of violence. Participants pointed to the construction of sex work as ‘dirty work’ and the role that this played in legitimising the violence that was directed at them by intimate partners. In relation to this positioning and its consequences in terms of justifications for violence, my analysis highlights occasions in which gender ideology is re-appropriated for the purpose of challenging the legitimacy of these interpretative frames. While gender politics is central to my analytic observations, my analysis demonstrates how intersections with race and class shape the specificities of FSWs experiences of IPV. In doing so, this study aims to broaden current insights into the phenomenon of IPV, as it does not only focus on gender discrimination, but on the complex interaction between various systems of oppression.

- Description: This paper contributes to the social learning literature. It argues that there is a need to give attention to the antecedent literatures that inform understandings of the social in social learning; and the learning in social learning. These antecedent literatures (drawn mainly from sociocultural psychology, learning theory and realist social theory in this paper) are necessary in social learning research, if we are to avoid the problem of ontological collapse in social learning research. The concept of ontologi-cal collapse (after Sfard, 2006) refers to a tendency in modern sciences to objectify social processes. It is used in this paper to draw attention to the need to understand the complex social processes involved in social learn-ing (and the antecedent literatures that may enable us to do so). As such, it warns against reification in social learning research; and also warns against turning social learning into an object, devoid of complex learning processes and agentive reflexions, decision making and practices. To clar-ify this concept, the paper shares examples of instances of ontological collapse, showing that at times, the social learning literature itself can fall victim to the problem of ontological collapse. Drawing on the literature review work in two cases studies of social learning research that work carefully with the antecedent literatures, the paper demonstrates the im-portance of engaging carefully with these literatures to avoid ontological collapse in social learning research in the fields of environmental education and natural resources management.

- Description: Semiconductor materials used for making photovoltaic (PV) cells have defects and impurities due to constraints of keeping production costs low. Electrically active defects that are distributed over the bulk material lead to reduced overall performance of a photovoltaic (PV) cell. In this study an adaptable Light Beam Induced Current (LBIC) system was designed in order to characterize the local performance of PV cells. The system uses a laser source and objective lens mounted vertically above the sample on the X-Y stage. Two current pre-amplifiers are used for converting the photo-generated current from the PV cell and the signal from the reflection detector cell into a voltage that can be measured by the data acquisition board. Two configurations for measuring the photo-current maps of either bare cells or encapsulated PV mini-modules can be used. To add flexibility it was envisaged that the system would be built in such a way that it allows easy integration of carrier lifetime mapping capabilities while keeping costs to a minimum. The carrier lifetime measurement technique integrated into the LBIC system is based on the optical Open-Circuit Voltage-Decay (OCVD) method. In a single-crystalline silicon PV cell that was tested, photo-current and opencircuit voltage LBIC scans revealed shunting behaviour due to scratch marks on the front surface. The marks are believed to have been caused by poor handling during manufacturing process. Reduced photo-current due to edge shunting was observed towards the edges of the PV cell. In another sample of single crystalline silicon cell an edge shunt resulted in a 30 percent drop in photo-current measured. LBIC measurements performed on multi-crystalline cells revealed nonuniformities such as enhanced photo-current on one side of grain boundaries. These asymmetric enhancements of local photo-current are attributed to the incline of the grain boundary into the bulk of the material. LBIC results obtained from mini modules showed a high degree of mismatching from cell to cell. It is well known that mismatching can degrade the performance of a PV module with series connected cells. The LBIC measurements presented also illustrated the negative effects of delamination on the photo-current of PV modules. The LBIC measurements performed on mini PV modules highlight some of the benefits of using an LBIC technique as a tool for investigating PV cell’s local photo-current response. The effective lifetime maps obtained highlight the importance of optical OCVD method as a tool that can be used in conjunction with conventional LBIC technique. Effective minority carrier lifetimes around 40 ms were measured on a single crystalline silicon cell of 2.5 x 2.5 cm2. Local features such as cracks and lifetime degrading defects were revealed by LBIC maps and were also confirmed on effective lifetime maps. The results presented demonstrate the importance of using effective carrier lifetime maps to complement photocurrent maps of PV cells and identification of areas where defects are located.

- Description: The aim of this thesis was to explore the experience of “self” within the clinical context of adult survivors of childhood trauma. Childhood trauma in this study referred to a range of childhood experiences of emotional and physical assault, including encounters with various kinds of abuse and neglect. The focus was on the experience of a sense of disintegration and dislocation, associated to aspects of self being in conflict. This was explored from theoretical perspectives of Jungian analytic psychology, as well as art therapy.Answers were sought to the questions of how claywork, as a form of art therapy, may facilitate the integration of the self and contribute to the development of a healing dialogue with feared and hated aspects of self. Grounded in Jungian theory, integration of the self was conceptualised as a movement towards “differentiating wholeness”. The study took the form of a phenomenological-hermeneutic case study. One participant’s experience of making and discussing a clay sculpture in a therapeutic setting according to Edwards’ method, was analysed thematically. It was concluded that the potential of claywork in therapy to facilitate the integration of the self is related to three aspects. Firstly, claywork in therapy may promote a concrete personification of feared and hated aspects of self, which may enable the maker to view these aspects from a distance, and learn to understand them in a new way. Secondly, claywork in therapy may facilitate the safe ‘unearthing’ of repressed feelings as well as hidden aspects of the personality. Thirdly, claywork’s potential to mediate symbolic functioning was shown to be an important aspect of the integration process. These findings confirmed and extended existing theory regarding the usefulness of claywork in psychotherapy with adult survivors of childhood trauma. Brief recommendations for future research were provided.

- Description: There is a considerable amount of literature arguing that economics and business journalism is growing. This subfield of journalism is important as economics issues impact on everyday lives of the people. Media have an important role to inform people about the economy and give them a voice to take part in public debates. The down side though is that economics journalism is criticised for not serving the public well in this aspect. Evidence suggests that economics journalism lost its critical character and that there is closer in economics debates. Using content analysis, this study examines coverage of inflation as reported by South African print media. Three major findings emerged: 1) Evidence shows that there are a variety of cases of inflation. 2) There are also similarities among newspapers on what they view as causing inflation. 3) However, media do not draw sources from all sectors of society. The elite, who are educated people and government officials, are over-accessed while the ordinary citizens - although also affected by inflation – are marginalized. Company and government sources top source lists in the media. It is argued that sources play an important role in shaping the news content. They do so by identifying problems and prescribing potential solutions. They set parameters and define terms of reference. However, media also play a mediating role. They do so by selecting sources and structuring sources in stories. They may chose to quote or report what their sources say and even comment on it. This study concludes that in South Africa ordinary citizens have no voices in economics debates. Media used bureaucratic sources only and that is a consonant agenda on inflation coverage amongst newspapers. The heavy reliance on bureaucratic sources and the exclusion of some sectors of society in sources lists raises questions about impartiality of these sources on issues relating to their organisations and institutions. These are not viable sources that could provide information that could expose abuse of power.

- Description: There is a considerable amount of literature arguing that economics and business journalism is growing. This subfield of journalism is important as economics issues impact on everyday lives of the people. Media have an important role to inform people about the economy and give them a voice to take part in public debates. The down side though is that economics journalism is criticised for not serving the public well in this aspect. Evidence suggests that economics journalism lost its critical character and that there is closer in economics debates. Using content analysis, this study examines coverage of inflation as reported by South African print media. Three major findings emerged: 1) Evidence shows that there are a variety of cases of inflation. 2) There are also similarities among newspapers on what they view as causing inflation. 3) However, media do not draw sources from all sectors of society. The elite, who are educated people and government officials, are over-accessed while the ordinary citizens - although also affected by inflation – are marginalized. Company and government sources top source lists in the media. It is argued that sources play an important role in shaping the news content. They do so by identifying problems and prescribing potential solutions. They set parameters and define terms of reference. However, media also play a mediating role.
