- Description: This thesis contributes to the history of the information and propaganda policy and practice of the government of the Federation of Rhodesia and Nyasaland by examining this government's pro-Federation print and radio propaganda for Africans in the Federation. Using a multi-theoretical approach, it analyses the character of this propaganda, highlighting its main methods and themes as well as the policy considerations, plus political and economic circumstances that gave rise to it. It also discusses how Africans in the Federation reacted to this propaganda and assesses its effectiveness in gaining the support of these Africans for Federation and the policies of the Federal government. The thesis argues that Federal government propaganda aimed at gaining the support of Africans for Federation was predominantly panic-driven propaganda and was the product of an information panic that lay at the heart of the very idea of Federation itself. This information panic arose out of the Federal government's belated recognition of the strength of African opposition to Federation and of how this opposition seriously threatened the continued survival of the Federation. It is also argued that this panic-driven pro-Federation propaganda elicited largely hostile reactions from the majority of Africans in the Federation and failed to persuade them to support Federation.

- Description: Biodiversity is the cornerstone of ecosystem functioning and the realisation that most rural African community livelihoods are directly dependent on ecosystem goods and services warrants its conservation. Invasive alien plants threaten biodiversity and compromise the ecosystem's ability to provide goods and services for rural communities, thereby negatively affecting livelihood strategies. Information on IAPs is lacking in most African countries, thus, the livelihood effects of Invasive Alien Plants (IAPs) are not clearly understood. In Zimbabwe, Cylindropuntia fulgida var. fulgida (Cff) has invaded Gwanda district in the Matabeleland south province compromising local household capital assets that contribute to livelihood strategies and altering the ecosystem. This study exposed the rural worldview of the environment, the effect that Cff has on local livelihood strategies and the effectiveness environmental management institutions in rural Gwanda district. The study followed a post positivist paradigm. The impacts of IAPs on rural communities in Zimbabwe were analysed by looking at the livelihood stresses that arise because of Cff. The research used multi-stage sampling to select a representative sample of respondents. Primary data was collected using semi-structured questionnaires, group discussion and key informant guides. Furthermore, document analysis was conducted to collect secondary data. The data analysis process used Computer packages Microsoft Excel, SPSS and NVIVO. Results showed that livelihood benefits that species in the natural environment provide strongly influence environmental perceptions of rural African communities. Additionally, the study showed that Cff compromises the local ecosystem and reduces its ability to support the dominant livelihoods in the study area. The long-term result of such a situation in the absence of control is increased poverty and the failure to realise sustainable development. However, results indicated that IAPs could also improve the poverty situation of a community before they have reached the threshold points. It is therefore imperative to know the threshold points of an invasive plant in order to ascertain the efficient point to intervene. The study also showed that benefits of invasive plants accrue to different members of a society at different times (private/public). This knowledge allows the adoption of efficient and effective control strategies.

- Description: South African riparian zones have been heavily degraded through anthropogenic activities such as dam construction and extraction of water for irrigation, which has resulted in a loss of ecosystem services and functioning. A consequence of such disturbances to riparian areas is in their susceptibility to invasive alien species (IAS). One such IAS is the giant reed, Arundo donax L. (Poaceae), introduced to South Africa in the 1700s largely for erosion control. Arundo donax has since greatly expanded in the country and is now one of the most abundant IAS. Arundo donax has been found to displace native vegetation and in South Africa this will most likely lead to the displacement of the native tall-statured grasses, Phragmites australis (Cav.) Trin. ex Steud. and Phragmites mauritianus Kunth. This study aimed to enhance our understanding of the tall-statured grasses A. donax, P. australis and P. mauritianus to better manage them in riparian areas. For A. donax, biological control is seen as the most viable option to control stands in the long-term. However, before such a programme is put in place, it is important to first collect baseline data that can be used to guide the direction of the biological control project in South Africa. For the Phragmites spp., despite being a dominant vegetative type in riparian areas, very little is known about their status in South Africa. Furthermore, there have been increasing reports of both Phragmites species having an expansion of their range and abundance. In North America, there has been a similar trend of reed expansion and through molecular work it was determined that a cryptic invasion has occurred with the introduction of an invasive non-native haplotype from Europe. It is therefore unknown if Phragmites spp. populations are expanding due to anthropogenic activities or due to a cryptic invasion. To address these shortfalls in knowledge the study investigated the tall-statured grasses in two parts; firstly, molecular techniques are used to explore the plant origin and genetic diversity of A. donax, P. australis and P. mauritianus and secondly using the Enemy Release Hypothesis as a framework, herbivore assemblages for each reed was determined across their distribution in South Africa. Molecular-techniques determined that both P. australis and P. mauritianus had only one haplotype - known as haplotype K and haplotype V respectively, across their distribution. For P. australis, haplotype K shares a close connection with populations from a Mediterranean lineage and this was further confirmed with a shared grass-waxy band. The direction and timing of genetic exchange between the two regions could not be ascertained and thus still remains unknown. Microsatellite analysis determined that both Phragmites spp. had a high genetic diversity compared to worldwide lineages. With no evidence of any cryptic invasions of haplotypes from other regions, both Phragmites spp. populations are likely to be native to South Africa. For A. donax all populations across South Africa were determined to be haplotype M1; a cosmopolitan haplotype that has an ancient native range in Afghanistan and Pakistan (Indus Valley). Populations were found to have no genetic diversity and thus can be considered one clone. A pre-introductory survey determined a list of herbivores associated with each tall- statured grass. For A. donax, a total of seven herbivores were found. Of these, one herbivore, a galling wasp, Tetramesa romana Walker (Hymenoptera: Eurytomidae) was found to be highly abundant and widely distributed in South Africa. Tetramesa romana is already a biological control agent in North America and thus is likely exerting some pressure on A. donax populations in South Africa. For both Phragmites spp. a total of ten herbivores were found, although having higher species richness compared to A. donax, when compared to other regions, these native species have a relatively low species richness. Providing baseline data on plant origin, genetic diversity and herbivory on A. donax, P. australis and P. mauritianus has provided important information on managing these species in riparian ecosystems in South Africa. For the Phragmites spp. with no evidence of any cryptic invasions, it is recommended that reed stands continue to be managed as native species. Phragmites spp. are important dominant vegetative species and thus should be protected; however, if reed stands become expansive, control methods can be put in place to focus on managing spread and abundance. For A. donax, this study was able to provide pivotal information in guiding the biological control programme. By determining the ancient lineage of South African populations, research can be focused in this area to find potential biological control agents. Lastly, the pre-introductory survey determined that a biological control agent, T. romana was already established with an unknown introduction and also highlighted potential plant parts that should be targeted. In particular, no rhizome feeding herbivores were found in South Africa and therefore this highlights an important niche that should be explored in biological control agents.

- Description: Kuqikelelwa ukuba kukho amaXhosa (amaMfengu) angcambu zawo ziseMzantsi Afrika amalunga namakhulu amabini amawaka azinze eZimbabwe ukususela kwiminyaka yoo-18001900. Uninzi lwawo lufumaneka eMbembesi, eFort Rixon, eFilabusi, eKenilworth naseMotapa eBubi. Imbali ithi, inxalenye yala maXhosa ngawaseMpuma Kapa, afudukela eZimbabwe noCecil John Rhodes eqhuba iinqwelo kananjalo esebenzela uRhodes ngeminyaka yoo-1800. Le thisisi yongeza kulwazi olutsha malunga nala maXhosa aseZimbabwe, iphonononga ubume bolwimi, imbali nemvelaphi yala maXhosa azinze eZimbabwe lo gama ibonisa ukuba naphantsi kwayiphi na imeko, ulwimi luyakwazi ukuphila ngaphaya kwemida. Ulwimi nenkcubeko zingumtya nethunga, ngenxa yoko le thisisi yayame kakhulu kwinkcubeko. Iethinografi nembali yomlomo zisetyenziswe njengendlela okanye imethodi yokuqhuba olu phando. Iziphumo zolu phando zibonisa ukuba umhlaba, inkcubeko, iingoma, inkolo yobuKrestu, iincwadi ezingaphelelwa xesha zoncwadi lwesiXhosa, iteknoloji namakhasi onxibelelwano nomgaqo-siseko waseZimbabwe (2013) zibe zizixhobo ezidlale indima ebonakalayo ekulondolozeni nasekuphuhliseni isiXhosa eZimbabwe. Imiba ephathelele kumgaqo-nkqubo wesiXhosa eZimbabwe nayo iyaphononongwa, njengokuba isiXhosa ilulwimi oluthathwa njengolusesikweni eZimbabwe.Kusetyenziswa iithiyori ngeethiyori ezingobuni, kuquka nethiyori kaCollier (1997) apho abona ubuni njengolunamacala amabini; avowal kunye ne-ascription. Ubuni bamaXhosa aseZimbabwe buxoxwe ngokwayama kwi-avowal njengokuba uCollier (Ibid.) eyicacisa. Kwizindululo eziqulathwe kolu phando, kuboniswa ukuba ikho imfuneko yokuba iintsapho zaseZimbabwe zidityaniswe nezizalwane zazo eziseMzantsi Afrika. Ukufundiswa kwesiXhosa kwaneenzame zokusebenzisa isiXhosa njengolwimi lokufunda nokufundisa kwizikolo zamaXhosa ezikumabanga aphantsi kuyafuneka nako ukuba kuphandwe nzulu. , There are an estimated two hundred thousand South African amaXhosa who are mostly amaMfengu descendants living in Zimbabwe since the late 1800s-1900s. The majority are found in the areas of Mbembesi, Fort Rixon in Filabusi, Kenilworth and the Motapa area in Bubi. It is stated that some of the amaXhosa living in Zimbabwe came from the Eastern Cape with Cecil John Rhodes as domestic workers and on wagons during the 1800s. Therefore, this thesis provides new knowledge about amaXhosa living in Zimbabwe and gives an analysis of the sociolinguistic and historical background of the amaXhosa living in Zimbabwe while showing how a cross-border language can survive against all odds. The subject of culture has been dealt with as there is a reciprocal relationship between language and culture. Ethnography and Oral History have been used as methods for this research. The findings reveal that land, culture, songs, religion, South African Xhosa literature classic books, technology and social media, as well as the 2013 Zimbabwean constitution, are tools that have played a role in the survival and maintenance of isiXhosa in Zimbabwe. It also assesses Language Policy issues as isiXhosa is now an officially recognized language in Zimbabwe. Drawing on various theories on identity, including Collier’s (1997) understanding that identity is divided into avowal and ascription, the identity of the amaXhosa of Zimbabwe has been discussed in this thesis with an emphasis on avowal as discussed by Collier (Ibid.). Among other recommendations, this study further recommends that a research that looks at the reunion of the Zimbabwean amaXhosa with their South African relatives needs to be undertaken. It also recommends that the teaching of isiXhosa as well as attempts to make isiXhosa the Language of Learning and Teaching (LoLT) in the amaXhosa primary schools and pre-schools also needs to be researched further.

- Description: School-based violence amongst students in South Africa is a growing concern. Such violence is a great concern to all stakeholders involved in the school system. The more violence escalates; the more students are less likely to concentrate on their academic activities which then reduces their chances of success. There are weekly report broadcasts on the media on the death of students across the globe due school-based violence. School-based violence needs to be curbed and schools should be a safe environment where learning and teaching takes place not a battlefield where students live in fear of being the next victim. The aim of this study was to examine students’ experiences of school violence in Sarah Baartman District Municipality, Eastern Cape Province, South Africa. A qualitative approach and an exploratory research design were used in conducting this study as these approached allowed participants to share first hand experiences regarding the issue under investigation. A purposive sample was employed to select participants for the study. This technique allowed the researcher to select participants who displayed most of the characteristics of the larger population and who had sufficient knowledge on the issue under investigation. Forty participants were selected for the study as follows: 25 learners; 5 social Workers; 5 educators; and 5 members of the Representative Council of Learners from schools mostly affected by school-based violence. Data was obtained through semi-structured interviews; focus group discussions with students, social workers and educators; and observations. Data was analysed thematically and supported by the relevant literature. The findings revealed that there are high levels of school-based violence in Sarah Baartman District Municipality, however, the whole-school approach as a measure of combatting school violence, has proved to work in some parts of the Eastern Cape, the Western Cape and Kwazulu Natal provinces. Also, retributive forms of punishment show more positive results against corrective /corporal punishment. It is, therefore, recommended that the state should employ school and place social workers in schools in order to assist in addressing social issues within the school system. Stamping out inequalities among students will ultimately decrease school violence.

- Description: Among the diverse citizenry that comprise Commonwealth countries are persons affected by disabilities and who remain vulnerable and under-represented. In light of the challenges of under-representation and the stigmatisation of persons with disabilities globally, the democratic principles of the Commonwealth of Nations have been placed under scrutiny. Thus the constitutionality and fairness of governmental policies and national legislation are criticised for their degree of reflection and representation of the social and political rights of persons with disabilities. This thesis will critically analyse the national legislative and policy frameworks affecting persons with disabilities in selected Commonwealth countries. Comparisons will be made between these selected countries, namely Canada, India, Kenya and South Africa. The Commonwealth and subscription to the United Nations’ Convention on the Rights of Persons with Disabilities will serve as a standardised platform for comparisons. Comparisons of the legislative prescriptions of the respective countries will be instrumental highlighting the challenges in the representation of the rights and freedoms of persons with disabilities globally and in improving and strengthening legislative prescription affecting persons with disabilities. The varying levels of development amongst countries and the lack of appropriate infrastructure continue to be detrimental to the effective representation of persons with disabilities and the ability of national governments to develop strong and effective legislative and policy frameworks remains compromised. It is thus essential that attention is directed to the challenges facing countries so that appropriate actions and remediation can improve the vulnerabilities linked to persons with disabilities. This study adopts a theoretical and case law approach. It firstly provides a conceptual framework for disability. The conceptual framework comprises the perspectives on disability that have justified the approaches to persons with disabilities. Theories and values and the international legal framework relevant to persons with disabilities will be provided. The theories and values provide a traditional framework and play an instrumental role in guiding actions toward the effective development of public policy and prescription of legislation. The selected countries will be analysed as separate cases. The countries will be analysed individually prior to the comparative component to acknowledge the strengths, weaknesses and challenges facing each country in relation to its own structure and level of development. The findings are based on themes which emerge from the analysis of the legislation and policies affecting persons with disabilities in the selected countries. The findings are presented in a comparative format owing to the comparative nature of the study. Recommendations that flow from the comparative analysis and findings are proposed in the final chapter. The adoption of the proposed recommendations can strengthen legislative prescriptions affecting persons with disabilities both nationally and internationally and improve the representation of the rights and freedom of persons with disabilities in the global context.

- Description: Soil organic matter (SOM) plays a primary role in aggregation and stabilization of soils, hence reducing their susceptibility to erosion. In South Africa (SA), most soils have low (< 4 percent) soil organic matte (SOM) contents, making them susceptible to soil erosion. Little is known about SOM quality effects in soil stabilization in the SA context, it is therefore difficult to advocate specific organic matter sources in order to stabilize a particular soil. This study evaluated effects of different litter quality sources (Vachellia karoo (sweet thorn) leaf litter and Zea mays (maize) stover) on soil aggregate stabilization at a soil micro-level (soil aggregate), guided by the following specific objectives; (i) to characterize soil properties that influence the erodibility of soils in the Ntabelanga area, Eastern Cape (EC) Province, SA (ii) to assess fractionation of organic carbon during decomposition of different litter sources (iii) to determine rate of soil macroaggregate re-formation under different litter amendments (iv) to determine the influence of different litter quality on splash soil erosion and (v) to delineate the Ntabelanga area into different soil erosion sensitivity zones. Soil samples collected from a proposed Ntabelanga dam site, EC Province, SA, were characterized for factors influencing erodibility. Soil physical and chemical properties were analyzed, soil erodibility (K-factor) estimated using SOC content and surface properties and soil loss rates by splashing determined under rainfall simulations at 360 mm h-1 rainfall intensity. Soil loss was then correlated with the chemical and physical soil properties. SOC showed significant (P< 0.05) inverse relationship with soil loss. Soils samples were bulked to seven composite samples according to major soil horizons (orthic A, melanic A, pedocutanic B, red apedal B, saprolite, G horizon and prismacutanic B) in the areas of soil associations, macroaggregate (> 0.250 mm) were removed by passing through a 0.250 mm sieve. The remaining soil microaggregates (< 0.250 mm) were then mixed with high quality Vachellia karoo leaf litter (C/N = 23.8) and low quality Zea mays stover (C/N = 37.4) and incubated at 23oC for 30 weeks. Jars were arranged as a 7 × 3 factorial laid in completely randomized design (CRD) with three replicates. Data was repeatedly measured at 1, 3, 8, 14, 23 and 30 weeks after incubation: to determine the stabilization of SOM by fractionating the soil particulate organic matter (POM), rate of soil macroaggregate re-formation and influence of litter quality on splash soil erosion along a decomposition continuum. Free light fractions (Free LF), coarse particulate organic matter (CoPOM) and fine particulate organic matter (FiPOM) within macroaggregates (> 250 μm) decreased exponentially from week 1 to 30 and were significantly (p < 0.05) influenced by litter quality × soil horizon × time interactions. A similar trend for FiPOM fractions in macroaggregates was observed in the 53-250 μm microaggregates (p < 0.05). The greatest influence on changes in POM fractions occurred within the first 3 weeks of incorporation. Both V. karroo leaf litter and Z. mays stover significantly stabilized the macroaggregates within the first 3 weeks after incubation. Cumulative macroaggregates yields, mean weight diameter (MWD), percentage water stable aggregates (%WSA) and whole soil stability index (WSSI) in litter amended soils increased up to week 8 of incubation and thereafter gradually declined in all soils. An increase in macroaggregation resulted in increased MWD, WSSI values and large and small aggregates distribution. Aggregation was significantly higher in soils with higher clay content than sand content, suggesting that soil texture was highly influential in litter decomposition. Rate of litter decomposition was influenced by soil type × time interactions which determined extent and macroaggregation dynamics along a decomposition continuum. The amount of splashed sediments was determined from each soil horizon at 360 mm h-1 simulated rainfall intensity applied as either single 8minute rainstorm (SR) or 4 × 2minute intermittent rainstorms (IR) separated by a 72 h drying period. Results showed a reduction in splashed sediments under IR and SR storms in litter-amended soils during the first 8 weeks of incubation with gradual increase thereafter. More sediments were splashed under IR than SR and litter quality had no influence on splashed sediments per soil horizon. Soil horizons profile with more clay than sand particles enhanced the litter effects on the soil resistance against detachment. The amount of SOC loss was influenced by primary particle size distribution and initial SOC content of the soil. Rainfall pattern and the initial SOC content were the main factors by which different soils influenced SOC loss. More rainstorm patterns should be investigated on these soils.

- Description: Albeit in its infancy, South Africa’s LED practice is a benchmark of a large number of African countries in general and Sub-Saharan African countries in particular. The LED practice stands out, for widespread decentralisation of powers, massive and growing LED budgets, robust legal frameworks that govern its implementation and development of LED structures, amongst others. This study seeks to answer three critical questions: What theoretical LED facets (particular aspects) are available in literature? Are these facets being implemented in Nelson Mandela Bay Municipality (NMBM) and Buffalo City Metropolitan Municipality (BCMM)? Besides the effort and monies invested in ingraining LED in South Africa, are the levels of LED practices of the two municipalities deeply embedded in literature? The study utilises a purpose-built tool to measure the level at which LED practice of respective municipalities is ingrained in LED literature. The thesis employed both qualitative and quantitative research methods in order to provide scientifically adequate answers to this research. The former method was employed in identifying available LED facets while, the latter was useful in measuring the level at which LED practice in the two metros is embedded in LED theory. The research findings reveal presence of 6 LED facets, namely, enterprise development, locality development, livelihoods development, workforce development, community development and LED Governance. However, this study discovered that the aforementioned facets fail to cover other general items like the availability or unavailability of LED strategy, functional location of LED within municipal directorates and availability of a budget to drive the LED functions. In light of this, the researcher decided to group all the other key LED functions that he felt were not finding expression under the 6 facets identified in LED literature. This, then, led to the introduction of “General LED” facets. This facet, besides presenting a pre-cursor to the 6 other facets, manages to capture some key factors that are equally behind the success or failure of LED e.g. the LED strategy factor, a factor which a number of sources name “The heart” or “guiding compass” of successful LED implementation. The “General LED” facet contained other factors like: other plans that aided LED, experience of LED practitioners, budget allocation of the LED function, amongst others. The research found that all the 7 facets are being implemented in both municipalities, albeit to varying degrees. The two metropolitan municipalities’ LED practice, with respect to all the identified LED facets, provided some measure of their respective levels of embeddedness in LED theory using a purpose built tool. The embedded (ness) outcome proved that Nelson Mandela Bay Municipality’s LED practice was embedded in the LED theory across all the 7 facets, namely: general LED, enterprise development, locality development, community development, livelihood development, workforce development, and LED governance. The same analysis proved that Buffalo City Metropolitan Municipality’s LED practice was embedded in LED theory in all the other facets bar community development. The survey results revealed that there are inadequate or limited initiatives in Buffalo.

- Description: This research critically analysed the role, if any, that is played by the budgetary reforms in enhancing basic service delivery, with specific reference to the case of Amathole District Municipality. The main objectives of this study were to investigate and evaluate the causes of possible challenges encountered by the ADM in the implementation of local government budgetary reforms; to assess and determine the role played by budgetary reforms in promoting basic service delivery by the Amathole District Municipality; to analyse the extent to which budgetary reforms are used in the preparation of the municipal budget and the IDP; and to evaluate the level of ADM institutional capacity in delivering basic services to communities in terms of the municipality’s capital budget and financial plan. The study is premised on the fact that there is no guaranteed service delivery without a sound financial management and planning. In this study, it is acknowledged that municipalities in South Africa are struggling to implement the local government budgetary reforms; and as such, South African municipalities could succeed in rendering effective and efficient public services, provided the matters of governance are adhered to, as well as financial governance in particular. This research is solely based on the assumption that the Amathole District Municipality’s budgets and budget process, like other municipalities in South Africa, are done for the sake of compliance with the requirements of National Treasury and the MFMA – with less emphasis being placed on enhanced basic service delivery to communities. The study proposed to provide a brief literature review on the basic service delivery, with reference to the South African context, as well as a theoretical overview on the evolution of developmental local government budgetary reforms. The empirical survey and research methodology employed in the study are described, followed by the operationalization of the survey questionnaire used for gathering the field data. The research findings of the empirical survey are then statistically analysed, using statistical procedures. The qualitative data analysis involved thematic content analysis, being interpreted and reported on. The triangulation-research methodology was employed with the emphasis being on the quantitative and qualitative methodologies. The sample comprised councillors, officials and ward committee members. Questionnaires, with open and closed-ended questions, were employed for the councillors and the officials. Focus-group interviews were conducted with the ward committee members from the respective local municipalities.The findings strongly suggest that, the introduction of the budgetary reforms indeed resulted in a shift by municipalities from their core mandate – that is service delivery – to a more legislative-compliant mode of practice. Recommendations flowing from, inter alia, the results of the empirical study, are presented to improve financial governance and service delivery in the Amathole District Municipality, as well as in other municipalities in South Africa. If adopted, these recommendations should enable the Amathole District Municipality, as a development agent, to fulfil its developmental mandate, thereby addressing the matters of financial governance and service delivery.

- Description: This thesis is a comparative study in Francophone literature which analyses the supernatural factors in three African epics, namely the Sundiata or Mandingo Epic from West Africa by Djibril Tasmir Niane (1960), Emperor Shaka The Great : A Zulu Epic from Southern Africa by Mazisi Kunene (1979), and Nsongo’a Lianja : the National Epic of Nkundo People from Central Africa by Edmond Boelaert (1949). The study analyses similarities and differences between the supernatural figures in these epics and their respective societies using contextual and socio-critical theories. In this thesis it is demonstrated that the presence of supernatural forces is a sine qua non condition for the existence of the epic in the sense that : “the essential mark of the heroic personality in many African folk epics is its reliance on supernatural resources” (Okpewho 1979 : 119). This study shows that in Africa, supernatural forces play vital roles in the society and therefore dominate the African oral epic traditions. Furthermore, the study is significant in the sense that it tries to describe the worldview, especially the religious and cultural beliefs of the particular society or group that produces the epic. The thesis is made up of six chapters. In the first chapter, I outline the study’s subject matter, its aims and objectives, its significance, its assumptions and methodology. In the second chapter, I examine the impact of supernatural devices on the lives of the epic heroes Sundiata, Shaka, and Lianja, the predictions and divinations about their births, childhoods, exiles or epic journeys, their ascension to the throne as well as their genealogies and deaths. Such analysis allows one to identify the supernatural factors surrounding each stage of the life of the heroes, and to understand further the importance of supernatural forces in the communities and institutions where the heroes exercise their powers. In the third chapter, I discuss the typology of the supernatural forces in the heroic epics Sundiata, Shaka and Lianja, using Greimas’s theory of actants. I divide the characters into protagonists, accessories and opponents. In the fourth chapter, I examine the sources of the supernatural forces prevailing on Sundiata, Shaka, and Lianja. The chapter shows how supernatural agents act on the epic heroes and how these supernatural beings make or mar them in the course of the narratives. In the fifth chapter, I investigate the supernatural factors acting on the heroes’ opponents, and in chapter six, I examine the supernatural forces and heroism of the women in the three epics. In the conclusion, I demonstrate that this analysis of supernatural factors enables us not only to appreciate their place and function in the three African epics under study, but also opens a window onto the culture of the Mandingo, Zulu, and Mongo People’s : their activities, beliefs, taboos and the rules which organise their respective societies. , This thesis is presented in two parts: French and English.

- Description: Patients who are critically ill get often admitted to intensive care units (ICUs). The majority of these patients require support with their breathing and are thus connected to a mechanical ventilator. One aspect to consider in the mechanically ventilated patient is endotracheal tube cuff pressure (ETT) management. The management of ETT cuff pressure entails that nurses working in ICUs have the responsibility of ensuring that ETT cuff pressure is kept within normal range of 20-30 cmH20 for the safety of the patients in order to avoid complication of over and under inflation. Poor management of ETT cuff pressure places the mechanically ventilated patients under risk of tracheal injury. Tracheal injury may also be caused by over or under inflation of the ETT cuff. Over inflation of the ETT cuff can lead to the occlusion of capillaries lining the trachea at the cuff site, tracheal stenosis, and can also lead to the death of mucus membranes around the area, just to mention a few. On the other hand, under inflation of the ETT cuff, can lead to air leaks as well as aspiration of gastric contents into the tracheal tree. Therefore, in order to maintain ETT cuff pressure within normal ranges, evidence-based guidelines related to the management of ETT cuff pressure should be used. However, in Malawi the management of endotracheal tube cuff pressure in mechanically ventilated adult patients by nurses in ICUs is not well explored and it is not clear whether this practice is based on evidence-based guidelines. Furthermore, strategies on how to implement evidence-based guidelines in the ICU might not be known and poorly defined because of the complexity of the context. The study is therefore aimed at implementing and evaluating the effect of an evidence-based guideline on the management of ETT cuff pressure in mechanically ventilated adult patients by nurses in ICUs in Malawi using active (printed educational materials and monitoring visits) and passive (printed educational materials only) implementation strategies. The research study used a quantitative approach with multi-designs. Four phases were used in order to achieve the four objectives that were set. Phase one was the pre-test and used a survey design, two was the expert panel review of the evidence-based guideline, three was the implementation of the reviewed evidence-based guideline using a randomised controlled trial design and phase four was the post-test which used a survey design. The RCT included 25 participants from the control and 27 from the intervention group. Each group had three ICUs of which one in each group was from a private hospital and the other were government. Data collection in phases one and four was by a hand delivered pre-and post-questionnaire. In phase two the expert panel members with experience in critical care used the AGREE II Instrument to review the evidence-based guideline that was implemented. In order to gather data during the monitoring visits, the researcher recorded field notes. The applications that were developed by the University statistician consultant using visual basic applications in excel were used to analyse data. Two different implementation strategies were used to implement the evidence-based guideline. The control group used passive implementation strategy which was printed educational materials thus the evidence-based guideline and algorithm. The intervention group used both active and passive implementation strategies which was the printed educational materials thus the evidence-based guideline and algorithm plus monitoring visits by the researcher. In order to establish the effect of the implemented evidence-based guideline on the nursing care practice for the management of endotracheal tube cuff pressure an evaluative posttest survey was conducted in phase four of the research study. The results revealed that the majority of participants had gaps in both groups regarding nursing care practice for the management of endotracheal tube cuff pressure for the mechanically ventilated adult patients in the pretest but improved in the posttest. In the control group 52% had very low knowledge score, 16% had low score, 28% average, and 4% high score while in the category of very high score there was nobody. However, in the posttest those in the very low score were only 44% while the percentage in the low score remained 16%. There was an improvement in the average scores in the posttest such that only 44% were in this category. There was no one in the high and very high score in the pretest. On the other hand, in the intervention group, 78% had a very low score, 9% low score, and 13% were in the category of average score, while in the high and very high score category there was zero percent in the pretest. However, there was also an improvement in the posttest such that only 44% a very low knowledge score. But 19% had a low score, there were 37% in the average category and no one was in the high and very high score. Statistical analysis revealed that the results were not significantly different between and within groups. Improvements were observed in the two groups regarding the scientific knowledge scores for the nursing care practices in the posttest. Upon qualitative analysis of the data from the open-ended question, two main themes emerged thus the need for documentation of endotracheal tube cuff and the process of implementation the evidence-based guidelines. Sub themes such as lack of documentation; no part of routine care and monitoring not done at all were identified under the main theme of the need for documentation of ETT cuff pressure. The Guideline itself need to be clear; implementation strategies; follow up; incentives; supervision; incentives; time factor; resources or equipment required for successful implementation; nurses buy-in critical for the implementation; training detrimental to EBP implementation; nurses attitude crucial to implementation of EBGs and knowledge of nurses for guideline essential for the implementation were the sub themes identified under the main theme of the process of implementing the evidence-based guideline. All appropriate ethical considerations such as principles of autonomy and self-determination, confidentiality and anonymity, voluntary participation, right to receive treatment, informed consent, were adhered to throughout the research study. The research study was unique in nature because it was the first of its kind in Malawi and it contributed to the awareness of the recommended practice for management of endotracheal tube cuff pressure in the ICUs in the country by implementing an evidence-based guideline. The unique contribution of the study is that it is a challenge to implement evidence-based guideline in poor and resource constraint countries like Malawi.

- Description: As a result of maritime piracy attacks in the Gulf of Guinea, especially in the West Africa sub-region, off the coast of Nigeria the researcher started carrying out research in 2014 on the laws pertaining to piracy. In this regard Nigeria does not have the legal framework to effectively address the threat of piracy off its coast but a Bill entitled: “Piracy and Other Unlawful Acts at Sea (and Other Related Offences) Act” has been forwarded to the Nigerian National Assembly in order to criminalise ‘piracy and other unlawful acts at sea’. For this reason, the researcher deems it necessary to examine the provisions of the Bill to determine whether it is adequate to address the threat of piracy or whether there is a need to reform or improve it. As a result of the research, it was revealed that the Bill will never achieve the purpose for which it was drafted as the legal framework on piracy of the Bill has many limitations which makes it easier for perpetrators to escape punishment. In order to achieve the goal of this Bill, the researcher deemed it necessary to contribute by drafting maritime piracy legislation for Nigeria that effectively addresses the threat of piracy off its coast, relying on the preparatory work for UNCLOS and other global, continental and regional instruments relevant to maritime piracy. Relied upon also are comparative analyses of piracy legal system of Anglophone African States and Nigerian legislation. This draft legislation amends the limitations of the Bill and is in accordance with legal notions of piracy which emerge from the combination of the principles of criminal and international law.

- Description: The irrigation schemes had been established over the years and now are operational but there is no marked improvement in the living conditions of the rural farmers and households. Smallholder farmers still face numerous constraints in market participation that hinder smallholder farmers, irrigators and homestead growth which have been attributed to lack of access to markets and technical expertise. Despite the government efforts, smallholder farmers effectively functioning in the agro-food chains, high-valued markets and commercial agricultural markets are rare; this indicates that the objective to allow smallholder farmers to advance their livelihood through participating in commercial agro-food chains has not yet been met. Farmers in the Eastern Cape produce many crops which they mainly sell in informal local markets; there is minimal number of smallholder farmers supplying their produce to the formal markets. Irrigation development is very crucial to the development of the agricultural sector as it ensures improvement in yields and reduces rural poverty through creating rural employment, enhance smallholder farmers’ market participation and enhance market access policies by smallholder farmers as means to achieve the Sustainable Development Goals The study was conducted in the Eastern Cape Province and employed survey data obtained from 200 smallholder irrigated crop farmers and homestead gardeners. A multistage stratified sampling procedure was used in which the first stage involved selecting the study areas. This was followed by the selection of the district and then the respondents. The farmers were selected from three District Municipalities which have operational irrigation schemes, namely OR Tambo, Amathole and Chris Hani District Municipalities in the province. STATA and SPSS were used to analyze the data. The Heckman model was applied to examine factors influencing farmers’ decision to participate in market among crop producing farmers in the province. In the first stage Heckman analysis, the decision as to whether or not to participate (which is a binary choice situation) is used to undertake the maximum likelihood estimation (MLE). In the second stage, the conditional quantity sold (continuous variable) is assumed to follow a truncated normal regression model, whereby the MLE is estimated by fitting a truncated normal regression of quantity sold. Gross Margin and Net Farm Income were used to measure farm profit as well as multiple regression analysis to estimate determinants of profitability in the study area. Profit efficiency was measured using the normalized transcendent logarithmic profit frontier approach (translog). he descriptive statistics employed include means, percentages and frequencies mostly of the socio-economic characteristics of farmers in the study area. The results show that males were dominant with the representation of 61.7percent. The majority of farmers were aged and the mean age was 60 years, indicating that farmers in the province are old which has implication for productivity and market participation. High level of illiteracy is shown in the data and mean household size of 5 persons with the household head having at least obtained some primary school education.The irrigated crop farmers and homesteads were found to have farm size under 4 ha. About 86.5percent were full time farmers and Farming is their major source of livelihood. Smallholder irrigators and homestead gardeners derive their income from social grants and remittances. This thesis found out that majority of the farmers do not participate in markets. In this instance, farming becomes a scapegoat for failure to enter alternative labour markets. The average annual on-farm production income from smallholder irrigators was R7 860.27 and homestead gardeners was R5 915.50. The empirical results from probit model suggest that age of the farmer, level of education of the farmer, household size, farm organization, access to extension, distance to markets, occupation and farm experience were some of the key determinants that had significant and positive effects on farmers’ decision to participate in markets while access to credit, transport to the markets and farm size were some of the key determinants that had significant and negative effect on farmers’ decision to participate in markets. The volume of crops sold to the market is determined by gender, age, years spent in school, distance to the market, farm experience, household size, access to extension, membership in farm organization and non-farm income.

- Description: Historically psychobiography has focused to a large extent on the study of pathology in human development. In recent years, scholars in the field of psychobiography have recommended that studies with a eugraphic focus be undertaken, thereby investigating optimal human development. Milton Hyland Erickson (1901-1980) was an American psychologist and psychiatrist. An extraordinary creative individual who conducted pioneering work in the field of hypnosis. Whilst vast publications of his academic work exist and his work is continued through the Milton H. Erickson Foundation and its global subsidiaries, in comparison, his life story has not been the focus of much study. The psychobiographical merit of Erickson as the subject of the study was based on his involvement in interesting and important events, as well as his resilient attitude towards life, during even dire moments. The focus of this psychobiography was to conceptualise Erickson’s life in terms of the principles of Adler’s Individual Psychology and Peterson and Seligman’s Character Strengths and Virtues Classification. Through this process it was aimed to provide descriptions and interpretations of Erickson’s personality in order to illuminate aspects such as his creativity, service to others, and optimism. The study is written from the first person perspective and is rooted in the interpretive paradigm. It utilises a qualitative research approach in order to gain an in-depth understanding of Erickson’s finished life and thereby taking into account contextual factors. The two theoretical frameworks guided the iterative data collection and data analysis processes and the data were organised into a descriptive framework. The method of data analysis was idiographic thus describing the uniqueness of Erickson life. Strategies such as the triangulation of data sources and theory, focusing on aspects of saliency, trustworthiness, and ethics were employed to ensure reliable data extraction and interpretation. The study revealed that both theoretical frameworks were appropriate in their description and interpretation of Erickson’s personality and character strengths. Of significance was the protective role that creativity, social interest, hope, and optimism played against trauma and these emerged as central themes in Erickson’s life in terms of his psychological wellbeing. The findings on creativity and social interest are supported by existing research and theory but also highlight perspectives for future research. Creativity is a key component of knowledge production and therefore research in this area could improve our understanding of how it can be nurtured and developed across the lifespan. Whilst the construct of social interest was integral to this study its validity in terms of providing adequate explanations of how individuals balance their own needs against the needs of others was examined and suggestions of where the theory can be elaborated were highlighted.

- Description: This thesis focuses on mineral governance and how it can contribute to ameliorating human development challenges in Ghana. The study adopted the human centered mineral resource governance approach to assess the mineral governance structure in Ghana and identified that, the current system is a colonial legacy and does not promote human development in Ghana. The study, whilst recognizing the legacies of colonialism, argues that in order for mineral resources to be managed responsibly to promote human development, there should be a paradigm shift to focus on how mineral resources are governed. As a result, the study, relying on the human centered development approach investigates how mineral resources can be governed to promote development in Ghana, with specific focus on the mineral wealth Western Region of the country. Due to the finite nature of mineral resources, the human centered development approach argues that revenues from mineral resources should be invested in human capacity building and medical care delivery. Further, the mining sector should be integrated with other non-mining sectors of the economy to create jobs and provide alternative livelihoods which will go a long way to assist in the general expansion and growth of the country‟s economy. Although this thesis is a case study of mineral governance in Ghana, it can serve as a springboard to appreciate the role mineral governance can play in promoting people centered development in other sub – Saharan mineral wealth countries.

- Description: Over the recent past, Uganda has experienced disproportionate volatility in inflation alongside rapid growth of unemployment. Whilst inflation has been curtailed to single digit figures since the economic crisis of the 1970s, nevertheless, in the recent past, inflation volatility and unemployment have constrained Uganda’s growth outlook. Like many various developing countries, Uganda has interacted monetary and fiscal policy frameworks as macroeconomic tools to spur productive growth. Most developing countries like Uganda continue to grapple with the challenges of jobless growth which is largely attributed to unstable inflationary pressures as well as low investment which further eggravated rapid expansion in unemployment levels. Government policy efforts have recently been greatly inhibited by rising youth unemployment rates in the country, this has greatly affected Uganda’s growth dynamics. Whilst developed countries have successfully used monetary and fiscal policy frameworks in their pursuit to macroeconomic stability, due to their complex structural economic dynamics, low income countries face challenges in implementing both monetary and fiscal policy to stabilize their economies. Central banks across all countries strive for low and predictable inflation as key in fostering economic growth. The debate over the applicability between monetary and fiscal policy frameworks in the pursuit of enhanced growth continues among policy analysts. The general observation especially in low income countries pertains to the use and effective coordination of monetary and fiscal policy in efforts to stabilize these economies. Despite numerous public expenditure reforms implemented and decline in poverty levels in Uganda, unemployment continued to rise over the past decade consequently inhibiting the country’s growth prospects which has ultimately undermined the econoimy’s capacity to external shocks. Keynes and the monetarists ignited the contentious debate over the superiority between monetary and fiscal policy frameworks which has transformed macroeconomic policy application. A conducive private sector environment as well as large expansions of infrastructure are key fundamental aspects of the development strategy in developing countries, they enhance growth in per capita income. Whilst the monetary authority emphasizes price stability when formulating policies, the fiscal authority pursues its objectives accommodative of the underlying circumstances in the economy. This study aimed to establish an econometric model to predict the impact of monetary and fiscal policy on unemployment and inflation in Uganda using annual time series data for the period 1980 to 2013. The study sought to investigate the influence of monetary and fiscal policy variables on the Ugandan economy in relation to unemployment and inflation. The analysis in the study is based on a twofold oriented objective. The first objective was to investigate monetary and fiscal policy dynamics in Uganda in relation to unemployment. The second objective examined the conduct of monetary and fiscal policy framework on inflation in Uganda. The study analysis begins with a review of literature on the various monetarists and Keynesian theories in relation to the underlying monetary and fiscal policy frameworks. Considering the analysis was a twofold objective, two empirical models linked to unemployment and inflation as well as their relative determinants are specified. The Empirical literature review examined in the study is based on various monetary and fiscal policy theories as well as empirical works by Keynesians, classical economists and the Friedman views. The time series data used were obtained from published sources of the World Bank and IMF, the Uganda Bureau of Statistics (UBOS), Ministry of Finance, Planning and Economic Development (MoFPED) statistical reports and annual statistical drafts from the Uganda Revenue Authority (URA) and Bank of Uganda (BOU). To empirically investigate the influence of monetary and fiscal policy variables on unemployment and inflation in Uganda, considering the use of two dependent variables i. e unemployment and inflation, hence, two estimation techniques were applied in the study namely; the Modified Ordinary Least Squares that comprise of FMOLS and DOLS and the Autoregressive Distributed Lag (ARDL) approach. The estimation analysis in the study contains two main parts which are spread over two chapters. The first part of the analysis deals with the effects of fiscal and monetary policy on unemployment. The estimation techniques applied in the study included the Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS) applied to a Vector Autoregressive (VAR) model. The analysis regressed monetary and fiscal policy aggregates on unemployment in a twofold objective. The first sub section regressed fiscal policy aggregates on unemployment using; total government expenditure, total government revenue, tax revenue and trade openness on unemployment using both FMOLS and DOLS techniques. The second sub-section regressed monetary policy on unemployment using; interest rates, money supply, real effective exchange rates and inflation being regressed against unemployment. To test for presence of unit root among the variables of the sample period of 1980 to 2013, the study employed three approaches; i.e. the Augmented Dickey Fuller (ADF) test, Phillips-Perron (PP) test and Kwiatkowski–Phillips–Schmidt–Shin (KPSS) test. Included in this analysis is the test for structural breaks to further determine stationarity in the data series. The results revealed the presence of structural breaks. Structural breaks tend to inhibit stationarity among the variables at levels. However, when presence of structural breaks is taken into consideration, it simplifies empirical estimation analysis under review. The Johansen Cointegration approach was further applied to establish existence of a stable long-run relationship between monetary policy and fiscal policy as well as their respective variables included in the model in relation to unemployment, this further entailed estimation of FMOLS and DOLS in the model estimation analysis. The results from the above analysys show a negative and statistically significant relationship between total government expenditure (LGOVTEXP) and unemployment (LUNEMPLOYMENT). However, tax revenue, trade openness as well structural reforms which denotes the (SB) coefficient all show a positive and significant relationship with unemployment. Additionally, total government revenue (LGOVTREV) shows a negative relationship with unemployment although statistically insignificant. The DOLS results in this analysis all show statistically insignificant results between all the variables and unemployment. The second subsection using DOLS, analysed the impact of monetary policy on unemployment, revealed a negative and significant relation between interest rates, real exchange rates and structural reforms (SB) with unemployment. Money supply indicates a negative but statistically insignificant relationship with unemployment. However, inflation has a positive and statistically significant relationship with unemployment. The normality tests conducted indicate normal distribution of the residuals. Similiraly, the AR inverse roots show stability of the models estimated whilst the multi-collinearity and Wald tests all showed unbiased estimation results. Having analysed the effects of fiscal and monetary policy on unemployment the interest was to further test the impact of fiscal and monetary policy on inflation. This part constitutes two sub-sections. The ARDL approach ws used to analyse the influence of fiscal policy on inflation. The results reveal a negative and statistically significant relationship between inflation (DLINF) and total government expenditure (DLGOVTEXP) both lagged twice. Similiraly, total government revenue (DLGOVTREV) and tax revenue (DLTAXREV) both lagged once indicate a negative and statistically significant relationship with inflation. However, unemployment lagged three times indicates a negative and statistically insignificant relationship with inflation whilst trade openness lagged three times has a positive and satatistically significant relationship with inflation. The Granger causality test results revealed among all the fiscal policy aggregates used, only inflation Granger causes total government revenue. The second part on the effects of fiscal and monetary policy on inflation used monetary variables; interest rates (DLINT), money supply (DLMS) and real exchange rates (DLREER). The ARDL results revealed all coefficients to have positive signs. Inflation and real exchange rates lagged five and four times respectively have a positive and significant relationship with the dependent variable of inflation. However, interest rate and money supply lagged five and three times respectively show a positive and statistically insignificant relationship with inflation. The estimated model showed no evidence of presence of serial correlation through numerous diagnostic tests performed. These include; heteroscedasticity, residual normality and misspecification tests as well as the Cusum stability tests. Under the analysis of monetary policy dynamics on inflation, the Granger causality test revealed that inflation Granger causes interest rates. Similiraly, real exchange rate Granger causes inflation. The ARDL results in this sub-section suggest that inflation regressed against its own lagged values is statistically significant in explaining variations on inflation. Further, interest rates, money supply and real exchange rates significantly explain variations in inflation during the period under review. The results from the above analysis suggest that firstly, the fiscal authority in Uganda should formulate dynamic as well as robust fiscal reforms that can effeficiently be coordinated with sound monetary policy reforms. This ought to stimulate meaningful economic growth in the economy which would further enhance employment growth. Secondly, policy authorities should implement macroeconomic policies which harmonise public spending whilst at the same keep inflation subdued. In this regard, inflation targeting policies should be strengthened. Thirdly, the macroeconomic policy framework in Uganda should be coordinated with strong employment targeting policies in an effort to broaden labour market dynamics.

- Description: This thesis presents novel asymmetrical and symmetrical lanthanide phthalocyanines (Pcs) characterized using a number techniques including proton nuclear magnetic resonance, electron spin resonance, time correlated single photon counting, FTIR spectrometry, MALDI-TOF mass spectrometry, UV-Vis spectrometry, Raman spectroscopy and CHNS elemental analysis. The design of theses lanthanide Pcs takes the form of mononuclear, binuclear, trinuclear, bis- and tris(phthalocyanines). Nanomaterials such as zinc oxide nanoparticles (ZnO NPs), multi-walled carbon nanotubes (MWCNTs) and graphene oxide nanosheets (GONS) (oxidized and reduced) were employed for covalent linkage to mono- and binuclear phthalocyanines as conjugates. Transmission electron microscopy was used to characterize ZnO NPs, MWCNTs and GONS alone and when linked to lanthanide Pcs. Lanthanide Pcs alone and when linked to ZnO NPs, MWCNTs and GONS where embedded in polymers such as poly (methyl methacrylate) (PMMA), poly (bisphenol A carbonate) (PBC) and poly (acrylic acid) (PAA) for thin film preparation. The thickness of the thin films was determined by utilization of the knife edge attachment of the A Bruker D8 Discover X-ray diffraction (XRD). Optical limiting properties of lanthanide Pcs alone and as conjugates in solution and when incorporated into polymers were determined by employing a Z-scan technique. It emerged that low symmetry lanthanide Pcs (19, 20 and 21), the blue forms of bis(phthalocyanines) (only in solution; 24 and 28) as well as tris(phthalocyanines) (30 and 31) exhibit low limiting threshold (Ilim) values in solution and thin films (particularly PBC and PAA). The low limiting threshold values make these lanthanide Pcs reliable optical limiters.

- Description: This work describes the synthesis, photophysical and nonlinear optical characterizations of alkynyl Pcs (1, 2, 3, 8 and 9), 1,2,3-triazole ZnPc (4), mercaptopyridine Pcs (5, 6 and 7) and amino Pcs (10 and 11). Complexes 1, 2, 4, 7, 8, 9 and 11 were newly synthesized and characterized using techniques including 1H-NMR, MALDI-TOF, UV-visible spectrophotometry, FTIR and elemental analysis. The results of the characterizations were in good agreement with their molecular structures, and confirmed the purity of the new molecules. Complex 10 was covalently linked to pristine graphene (GQDs), nitrogen- doped (NGQDs), and sulfur-nitrogen co-doped (SNGQDs) graphene quantum dots; gold nanoparticles (AuNPs); poly(acrylic acid) (PAA); Fe3O4@Ag core-shell and Fe3O4- Ag hybrid nanoparticles via covalent bonding. Complex 11 was linked to Agx Auy alloy nanoparticles via NH2-Au and/or Au-S bonding, 2 and 3 were linked to gold nanoparticles (AuNPs) via clicked reactions. Evidence of successful conjugation of 2, 3, 10 and 11 to nanomaterials was revealed within the UV-vis, EDS, TEM, XRD and XPS spectra. Optical limiting (OL) responses of the samples were evaluated using open aperture Z-scan technique at 532 nm and 10 ns radiation in solution or when embedded in polymer mixtures. The analyses of the Z-scan data for the studied samples did fit to a two-photon absorption mechanism (2PA), but the Pcs and Pc-nanomaterial or polymer composites also possess the multi-photon absorption mechanisms aided by the triplet-triplet population to have reverse saturable absorption (RSA) occur. Phthalocyanines doped in polymer matrices showed larger nonlinear absorption coefficients (ßeff), third-order susceptibility (Im [x(3)]) and second-order hyperpolarizability (y), with an accompanying low intensity threshold (Ium) than in solution. Aggregation in DMSO negatively affected NLO behaviour of Pcs (8 as a case study) at low laser power, and improved at relatively higher laser power. Heavy atom-substituted Pcs (6) enhanced NLO and OL properties than lighter atoms such as 5 and 7. Direct relationship between enhanced photophysical properties and nonlinear effects favoured by excited triplet absorption of the 2, 3, 10 and 11 in presence of nanomaterials was established. Major factor responsible for the enhanced nonlinearities of 10 in the presence of NGQDs and SNGQDs were fully described and attributed to the surface defects caused by the presence of heteroatoms such as nitrogen and sulfur. The studies showed that phthalocyanines-nanomaterial composites were useful in applications such as optical switching, pulse compressor and laser pulse narrowing.

- Description: This thesis seeks to examine the ways in which Africans and African scholarship in particular have relied on the West to lead the way in scientific inquiry, theory and ways of approaching literary texts thus the stunting effects of this in the growth and development of uniquely African literary scholarship and theorising. In his seminal work, Decolonising the Mind, Wa Thiong’o (1987a) stresses that “...how we view ourselves, our environment even, is very much dependent on where we stand in relationship to imperialism in its colonial and neocolonial stages; that if we are to do anything about our individual and collective being today, then we have to coldly and consciously look at what imperialism has been doing to us and to our view of ourselves in the universe” (Wa Thiong’o, 1987a, p.88). Although most African countries obtained their liberation decades ago, seemingly western cultural imperialism still dominates and plagues the African psyche; hence they largely look to the West and ways of the West for established and emergent theoretical conceptions. This thesis aims to interrogate popular western literary theories unquestioningly used to analyse African works, particularly feminism and post-colonial theory; furthermore, to show crucial factors not taken into account such as the evolving power dynamics in African societies, the role of the “sacred” or spirituality which often forms and informs the dynamics of the text, and lastly, based on the poetry of Nontsizi Mgqwetho, to advocate for the need for an African literary theory and put forward the essential tenets of such a theory. The poetry of Xhosa poet, Nontsizi Mgqwetho, is used to analyse the complexities and dynamics of African literary production written in African languages; her poetry is written in isiXhosa to a Xhosa audience, a far cry from the assumption that African literary texts are concerned with writing to the “centre” as post-colonial theorists claim. Her work explicitly provides Africans with an approach to overcome territorial and cultural imperialism; she sees within the African psyche and traditional values empowering modes of resistance against any type of domination and through her poetry illustrates meaningful ways that Africans can critically engage with and examine the positives and negatives of cultural exchange and or assimilation, and the effects thereof while at the same time remaining proudly Africa.
