A study of assimilation and alienation in West African fiction and psychic dislocation in South African fiction
- Authors: Poisat, Ross
- Date: 2019
- Subjects: South African fiction (English) , South African fiction -- History and criticism Assimilation (Sociology) Alienation (Social psychology)
- Language: English
- Type: Thesis , Masters , MA
- Identifier: http://hdl.handle.net/10948/43270 , vital:36776
- Description: This dissertation will provide a study of Assimilation and Alienation in West African fiction of Ferdinand Oyono’s Houseboy (1956) and Ayi Kwei Armah’s Why Are We So Blest? (1972) and Psychic dislocation in South African fiction of Wulf Sachs’s Black Hamlet (1936/1996). The dissertation plans to examine the specific effects of assimilation, alienation and psychic dislocation by examining them as central lines of argument in the respective texts. In Houseboy, the Catholic mission is depicted as being subordinate to the French Policy of Assimilation in colonial Cameroon. This dissertation examines how Oyono represents the manner in which the French catechists indoctrinated, dehumanized and made ‘other’ the colonized Cameroonian people. The relationship between colonial violence and trauma in Oyono’s text is also explored in relation to how the trauma of the colonized is expressed by them being the subject of and witnessing colonial violence at the hands of French Imperial agents. Oyono’s text was selected because it presents a counter-hegemonic portrayal of the French Policy of Assimilation and the Catholic mission’s complicity in this process. Why Are We So Blest? is analysed in terms of Armah’s depiction of the Modin’s relationship to a Western model of education, which is illustrative of his academic, racial and cultural alienation. The protagonist in Armah’s text can be seen as complicit in the history of colonial oppression due to his intellectual dependency on Western knowledge. Furthermore, this dissertation explores how the Modin is alienated by his relationships with his white academic superiors, who ‘other’, deny him agency, and infantilize him. Furthermore, the Algerian revolution functions as an expression of culture and the African intellectual, by being denied entry to it, is also alienated from the African masses. Armah’s text was selected because of its complex depiction of alienation. The literary analysis of Black Hamlet in this dissertation seeks to address the neglect of the fictional and imaginative aspects of the text in preceding studies. The representation of the psychic dislocation of John as a Shona nganga’s relationship to his ancestors is approached from a cultural and racial perspective in further examining his psychic dislocation in relation to the narrator. Furthermore, this dissertation investigates how Black Hamlet can be seen to suggest that psychic dislocation is tied to the hierarchal nature of colonial relations between John and the white narrator, and to John’s unreal experience of racialized South African and Zulu cultural place.

Genetic detection of some tick-borne bacterial and protozoan pathogens in ticks collected in Raymond Mhlaba local municipality, Eastern Cape Province, South Africa

- Description: Ticks and tick-borne diseases are becoming a major life threatening concern to wildlife, domesticated animals and human health. Besides causing skin damage, ticks infestations have become a growing burden in food security, economic losses and transmitting multides of pathogens. Little data and knowledge is available regarding the occurrence of etiologic agents of tick-borne diseases in the Eastern Cape of South Africa, hence the study was conducted and aimed at screening for genetic material of Anaplasma, Rickettisia, Ehrlichia, Borrelia, Babesia and Theileria species in ticks collected in Raymond Mhlaba District at Eastern Cape, South Africa. Ticks were collected from domesticated animals in Raymond Mhlaba Municipality, and were morphologically identified and processed for DNA extraction. Ticks were chopped into bits and DNA was extracted from the samples with commercial DNA extraction kit. The extracted DNA samples was used to molecularly identify the tick as well as assess the presence of tickborne pathogens belonging to Rickettsia, Babesia, Borrelia, Anaplasma and Erhlichia, and Theileria spp. by PCR using specific primer pairs published in literature. Positive amplicons were sequenced in a commercial sequencing facility. The obtained chromatograms were edited with Geneious bioinformatics software and were subjected to BLASTn and phylogenetic analyses using MEGA7 version for evolutionary relationships with curated reference sequences in GenBank. Nine hundred and sixty two tick samples were collected from domestic animals. Collected tick samples belonged to three genera, which were the Amblyomma, Rhipicephalus and Haemophalis in decreasing order of their abundance. Screening of tick DNA samples by PCR did not show presence of Babesia, Borrelia, Anaplasma and Erhlichia. 13 Positive PCR products were observed for Rickettsia and Theileria spp.. The positive amplicons were purified, sequenced and analysed for speciation of Theileria and Rickettsia. The presence of Rickettsia was detected in 60/994 (6%) from the three genera of ticks. Phylogenetic analyses shows that the sequences obtained are phylogenetically related to members of Spotted fever group Rickettsiae. Genetic material of Theileria spp. was detected from 10/994 ticks with an overall infection of 1% obtained in Rhipicephalus genera. Analyses shows that the sequences obtained are phylogenetically related to T. orientalis complex. The finding from this study therefore expands the knowledge on recent emergence of Theileria and Rickettsia spp. in Raymond Mhlaba Municipality in Eastern Cape, South Africa

Rhodesian African art, 1857-1974

- Description: ART is life, and life is for living. This is the essential function of Mankind. Everything interrelates. African life and thought are inseparable. Art is an implement of power; it bridges the gap between Man and his Gods, and Man and Nature. The ability to understand art, does not depend on the ability to see and appreciate but to understand the culture of the people, to know the past). When considering AFRICAN ART, one can be sure that the ART OF RHODESIA is certainly the last to come to one's mind; that is, if one excludes the Prehistoric Artist of Rhodesia and the ART of the Zimbabwian culture, and concentrates on ART executed after the PIONEER PERIOD (circa 1857) to the turn of the century. Comparatively little has been written on the aspect of local art, and when it bas, it is primarily concerned with SHONA SCULPTURE. Rhodesian art is primarily functional, and the range of materials as well as the range of techniques are equally vast. The art of sculpture and carving particularly in wood, is a well-known characteristic of Africa. Rhodesia, however, does not offer such a vast selection of traditional art today, whether in wood, stone or metal. The carvers in Rhodesia, unlike those of some African States have long since downed their tools as there are no longer the rituals that at one time inspired the artist. These rituals have almost died out and the Kings that were his patrons have been out of power for centuries. The destruction of traditional African values is inevitable because of cultural change, white civilization, and more recently, ex:ploi ta tion has forced the traditional carver to become a carpenter or to join a co-operative in order to provide Tourist Art.

- Description: "Come and see how the Nkanga work in their garden." The Malimba were large trough shaped zithers, 3' 10" long supported at either end by two large gourds upon which they were held. Owing to the lowness of the notes they produced, the sound of the drums drowned them. But the three players shook their long strings of red ochred hair in most ecstatic style as they played and sang. The Zithers were tuned as follows:-103, 90, 84, 76, 63 vs. Both 76 and 63 vs had two strings each. The strings are plucked about 4 inches from one end. The spectators crowd around the small group of zither players and drummers, who sitting on the ground or standing holding their hour glass drums between their knees, jump and shake their long locks as if they were possessed. They say several hours of this performance frequently gives the performers a kind of involuntary hysteria which takes time to calm. The drums appear to be played out of tune with the rest of the performance. Dance song for Isumbi dance with 2 hour glass drums (-14.31201-), 3 Malimba trough zithers (-10.3515-), Ndwala bells (-12.55-), flat tin rattles(-12.54-).

- Description: Liposomes are considered as potential vehicles for the delivery of anti-tuberculosis drugs (ATBD) due to their rapid uptake by alveolar macrophages, where the mycobacterium often resides. This may provide macrophage-targeting effects that would be key to site specific ATBD delivery using pH-sensitive liposomes, considering the pH-gradient found in the phagocytotic pathway. In this study, isoniazid (INH) was conjugated to 4-hydroxy-benzaldehyde via a hydrazone bond to yield isonicotinic acid (4-hydroxy-benzylidene)-hydrazide (INH-HB). This conjugate was encapsulated in crude soybean lecithin liposomes using film hydration method. INH-HB loaded liposomes (IHL) were characterized by means of dynamic light scattering, transmission electron microscopy, differential scanning calorimetry and X-ray diffraction. The release of INH from IHL was evaluated in media of different pH using a dialysis method. The particle size, Zeta Potential and encapsulation efficiency of IHL were about 945 nm, −62 mV and 89% respectively. In media of pH 7.4, 6.4, 5.4 and 4.4; the IHL exhibited respectively 22, 69, 83 and 100% of release over 12 h. In addition to possible targeted delivery, this pH-dependent release behavior may be suitable for minimizing the loss of INH by leakage from liposomes. The characteristics of IHL are promising for potential site-specific delivery of ATBD.

- Description: Antiretroviral therapy remains the most efective means of managing the human immune defciency virus/acquired immune defciency syndrome (HIV/AIDS). Application of therapeutics has been hampered by factors including poor bioavailability of most anti-retroviral compounds (ARV), side efects and an alarming emergence of drug resistant strains of the virus. Recent developments and use of drug delivery systems (DDS) has shown potential for improving the pharmacological profle of ARV. Amongst these complex DDS, liposomes have been explored for delivery of ARV. In this study, we have aimed at exploring efcient encapsulation of efavirenz (EFV), a potent ARV using diferent mass ratios of crude soybean lecithin and cholesterol. The EFV-loaded liposomes (EFL) were prepared using thin flm hydration and evaluated for particle size, zeta potential (ZP), encapsulation efciency (EE%), morphology and drug release studies. Diferential scanning calorimetry (DSC), X-ray difraction (XRD), energy dispersity spectroscopy (EDS) and Fourier transform infrared (FTIR) spectroscopy were used for comprehensive physicochemical characterization of EFL. EFL exhibited high encapsulation (99%) in 1:1 crude lecithin to cholesterol mass ratio. The average particle size and Zeta Potential of EFL were found to be 411.10±7.40 nm and −53.5.3±0.06 mV, respectively. EFL showed a relatively controlled EFV release behaviour that was similar to the dissolution profle of un-encapsulated EFV. This suggests that EFL represents a promising vehicle for efective EFV delivery while providing the advantages of a nano-scaled delivery system

- Description: This praise, which both begins and ends with song, are frequently recited by men at parties. The subject of their adulation may be their host, their cattle or any subject gratifying their senses. Adulation of elders is part of the sycophantic social system common to many tribes and especially cattle owners. The practise of interspersing spoken praises between song is also found among the Sotho of Basutoland. The word Engabo means literally a brave man and these praises were originally intended to praise fighting men. Nowadays woth no fighting to be done the praises have been extended to any gratification and particularly of the 'Pombe' banana beer. Engabo praise, with conical drum. laced, single, played with hands and clapping.

- Description: Property development is a complex process and is considered to be highly risky. The Global Financial Crisis (GFC) in 2009 had a negative impact on property due to various factors such as: increased interest rates; increase of stricter mortgage bond approvals; the recession and other possible financial regulatory factors. Property development plays a major role in the Gross Domestic Product (GFC)) of global economies worldwide, as well as in South Africa and changes in the supply and demand value of property impacts the performance of the property market. Thus, property development and real estate are one of the largest suppliers of employment. Property development entrepreneurs lack the project management skills to manage projects. In this study the related literature was reviewed and an empirical study was conducted. The empirical study was conducted using a quantitative statistical approach, by distributing research questionnaires to members falling within the sample population. The primary objective of the study was to develop a framework for perceived on-time delivery of property development projects. A descriptive survey was conducted among professionals in the property industry, and property development practitioners within South Africa. The findings suggest that the following variables influence the perceived ontime delivery of property development projects: Delays and disruptions, poor workmanship, PESTEL (political, economic, social, technological, legal and environmental) factors, shortfalls in full mortgage bond approval, town planning regulations, and the prevalence of a project management, framework amongst property developers, real-estate agencies and conveyancers. Furthermore, the following variables were identified in the empirical framework affecting the perceived on-time delivery of property development projects: PESTEL namely; Political Factors, Economical Factors, Social Factors, Technological Factors, Environmental Factors and Legal Factors. This study contributed to the South African property development body of knowledge, by determining the factors influencing the completion of property development projects, and on developing a framework for successful implementation of property development projects.
