- Description: In South Africa, the issue of lack of black pilot skills is a most talked about topic in commercial airlines. Airlines need to find the right set of skills and attitude to operate safely and successfully. Airline safety remains a topic of discussion, therefore airlines need ensure robustness of their selection processes. There are many requirements that a person has to meet before s/he can be offered a first officer job at an airline. The majority of the pilots in South Africa are white males. The study aimed to determine if there are statistically significant differences in cognitive ability test results between Black and White applicants for pilot positions with a South Africa airline. The test battery included a verbal reasoning test, numerical reasoning test, visual thinking, abstract reasoning test, spatial reasoning test, short term memory test, monitoring ability test, hand-eye coordination, sense of orientation test, reactivity test, and a multi-tasking test. The data were extracted with permission from a database maintained on behalf of the airline by an online test provider and subjected to a statistical analysis using measures of central tendency, and spread, in order to report on the significance of the differences between the groups. There is strong evidence that the White group performed better than the Black group on the majority of the tests. It is recommended that further research is done in order to determine the causes of these differences. A comparative study of results on other airlines’ recruitment selection tests and an exploratory study of the impact of socio-economic factors, education quality and language on cognitive ability tests are recommended.

- Description: In the Eastern Cape, a moisture gradient (from west to east) exists along the Escarpment where patches of Southern Mistbelt Forests (SMF) occur. There is a notable profusion of plants in these forests, but the factors that drive plant species composition and abundance in these patches is poorly understood and such knowledge is critical if we are to address or mitigate the problems imposed by global change. Many of our ideas on plant community assembly are based on the premise that species differ in their environmental requirements for successful regeneration, especially when young. The aims of this study were to document the floristic diversity of poorly known patches of Southern Mistbelt Forests in the Eastern Cape and identify the environmental factors that influence plant community composition in these forest patches. Twenty six forest patches across the Eastern Cape were sampled. In each forest 400m2 circular plots were constructed. The diameter at breast height and stem counts for the tree species was taken and the % cover of the herbaceous species was recorded. General collections were also made to supplement the plot data in order to obtain a comprehensive flora for each forest patch. All sampling was done during the summer season of 2013 and 2014. Using plot data, Hierarchal Cluster Analysis and Multidimensional Scaling Analysis were done to compare similarities between patches. Plots from the same forest patch clustered which indicated that the species composition in each forest patch was unique. However, this pattern went down when only tree species were considered. Plant diversity also varied between patches; with those located in the east being generally more diverse than those in the west are. Clustering patterns in fragmented communities and differences in species diversity indicate evidence of species “nestedness”. Analysis of nestedness indicated that these forest patches were significantly nested. To identify which environmental variables might be correlated with both species diversity and nestedness, twelve environmental variables was selected for analysis using Canonical Correspondence Analysis and Principal Component Analysis. Results show that Mean Annual Precipitation, Mean Annual Potential Evapotranspiration, and percentage of Organic Matter of the soil were most strongly correlated with the patterns of diversity observed in these forest patches. Regression analysis indicated that Mean Annual Precipitation accounted for most of the variation in species diversity, especially for the herbaceous species. The herbaceous species thus show a greater sensitivity to “climate filtering” as a consequence of rainfall gradients. With the implementation of suitable monitoring programs, changes in abundance or even local extinction of these species can act as an early warning indicator of the possible long-term effects of climate change on forest communities.

- Description: Black Locust (Robinia pseudoacacia L.) is an invasive deciduous, strongly suckering, broad- leaved tree that has the potential to be widely distributed across a large portion of South Africa. Robinia pseudoacacia has invaded all nine of South African provinces, with large infestations found in the Eastern Cape, Kwa Zulu-Natal, Free State and Gauteng provinces. The invasive tree has the potential to spread into livestock grazing lands in South Africa. Because R. pseudoacacia has the ability to spread and thrive in a variety of habitats and resists control, the distribution of the invasive tree into grazing land poses a problem for landowners. The potential economic impacts of R. pseudoacacia on agricultural production stem from the trees ability to reduce the carrying capacity of livestock. This study estimated the potential economic implications of R. pseudoacacia on agricultural production in South Africa, specifically looking at the livestock sector. The prevalence of R. pseudoacacia potential distribution was calculated by using a maximum-entropy predictive habitat model, MAXENT. The distribution of livestock, based on grazing capacity (ha/LSU), in South Africa was then determined. The potential direct economic impacts were estimated by assessing the impact of the potential distribution of R. pseudoacacia on the carrying capacity of livestock. The results showed that an infestation of R. pseudoacacia has the potential to reduce the gross margin in the livestock sector by between approximately R130 million and R961 million, dependent on the probability of invasion. Therefore, the potential invasion of R. pseudoacacia can have detrimental effects on the livestock sector in South Africa. The potential high levels of foregone income and business activity found in this study reaffirm the need to devote resources to develop a viable, economical and effective control method, such as biological control.

- Description: This dissertation is composed of two trials that were aimed at evaluating the effects of partially supplementing Baobab seed cake in broiler diets. In the first trail, performance and cost analysis of feeding birds a commercial starter diet from day-old to 21-days of age; then feeding a blend of the commercial finisher diet diluted by a mixture of baobab seedcake and ground maize from day 22nd to 35th were evaluated. The trial was conducted in an environmentally controlled deep litter housing system using 160 Ross 308 chicks of mixed sex that were randomly allocated into 4 treatments consisting of 16 pens of 1X2m2 area per pen, within similar environmental conditions. The trial diets were formulated as follows: T1 was 100 percent standard commercial starter diet, as a control; T2 had 95 percent (112g) commercial starter diet and 5 percent BSC-maize blend (2g BSC: 4g Maize); T3 had 85 percent (102g) of the commercial starter diet and 18percent BSC-maize blend (6g BSC + 12g Maize); and T4 had 75 percent commercial starter diet and 25 percent BSC-maize blend (10g BSC + 20g Maize). All diets (T1, T2, T3 and T4) percentages were calculated based on 120g being 100 percent of the diet. Each treatment consisted of 40 birds and 4 replicates, each replicate consisting of 10 birds per pen. Feed and clean water were provided ad libitum. Feed allocation and body weights were measured at placement, then weekly. Feed intakes (FI), body weight gain (BWG) and feed conversion ratio (FCR) were calculated; then the cost analysis of feeding each diet was conducted. No significant differences (P>0.05) were found amongst all growth performance parameters. The cost efficient treatment to feed, which accumulated the cheapest cost of feed per weight gain (R33.62/kg gain) was T2 (5percent BSC+MM). The second trial was conducted to evaluate the effect of feeding diets containing graded levels of baoabab (A. digitata) seedcake on performance, apparent digestibility and digestive organ weights of broilers chickens. A total of 200 Ross 308 day-old chicks of mixed sex were randomly allocated into 4 treatment groups (T1, T2, T3 and T4). The trial diets were as follows: T1 (control), was a commercial starter diet; while T2, T3 and T4 diets contained baobab seedcake meal at 0, 5, 10, and 15percent; respectively. Inclusion of BSC in diets only affected FI during the first and third weeks. In the first week, FI had significant differences (P < 0.05) during the first and third week of the trial, respectively. Birds in T4 had the least FI, while those in T3 had the highest (P<0.05). In the third week, T3 birds had the highest FI (P<0.05), while T1 birds had the lowest. Significant differences for changes in bodyweight were only evident in the second and forth weeks of the study. During week 2, birds in T had the highest BWG, whereas T4 birds had the lowest (P<0.05); however, in week 4, there were no statistical differences (P>0.05) amongst birds in T1, T2 and T4; respectively, while T4 had the lowest BWG (P<0.05). The FCR was not statistically different among treatment groups, except in week 3, where it was highest in T4birds with T3 birds having the lowest (P<0.05). No significant differences (P>0.05) were observed among treatment groups for all parameters that were considered for digestibility and digestive organ weights. Due to the fact that two different trials were conducted, it was concluded that blend of baobab seedcake and maize from the first trial can be supplemented up to 5 percent replacement level for optimum production; while up to 10 percent baobab seedcake graded level can be used on the second trial without resulting in any negative consequences on growth performance, nutrient utilization and digestive organ weights.

The Representation of Adult Family Members in Selected Children’s Books by Roald Dahl

- Description: This thesis focuses on the representation of the five adult family members (mothers, fathers, grandmothers, grandfathers and aunts) that are present in a specialised corpus of Roald Dahl’s children’s literature. Children’s fiction provides insight into how society views childhood as it reflects the dominant ideologies in society (Larkin-Lieffers 2010).The family is “central to most children’s literature” (Alston 2008: 2) which makes the analysis of the family in children’s fiction important. Society favours particular representations of the family, as well as men and women, and these representations are also reflected in the fiction available to readers. I have used Critical Discourse Analysis and Corpus Linguistics in order to establish how adult family members are represented in Dahl’s fiction. The physical description and the verbs of speech that collocate significantly with the different tagged characters are analysed to establish patterns in representation. Verbs of speech give the reader information that allows them to establish the emotion and attitude of the character and this helps the reader make judgements with regards to the positive or negative perception of the character. The repeated use of particular descriptions and verbs of speech primes the reader to associate particular features with certain characters and the evaluation provided by these features bleeds over onto the characters. There is evidence of a continuum of verbs of speech moving from verbs of speech with low pitch and low volume like ‘said’ to ones with a high pitch and high volume like ‘shrieked’. The tagged characters are discussed according to the continuum to establish any patterns the verb of speech use. Women were found to collocate with verbs of speech like ‘shrieked, ‘screamed’ and ‘wailed’ which suggests that women are more hysterically emotional while men collocate with verbs of speech like ‘shouted’ and ‘yelled’ which were less hysterical and suggest aggression. Aunts were the exception to this pattern as they collocated with more masculine verbs of speech, like ‘shouted’. These patterns help establish whether or not the representations follow the dominant ideologies of women being emotional and home bound and men being aggressive and more active in the public sphere.

The role of transformative mediation in post-electoral violence: the case of Kenya 2007-2008

- Description: Free and fair elections, accompanied by smooth transitions of democratically elected leaders, constitute one of the key pillars of democracy. The dawn of democratisation and advent of multi-party politics after the end of the Cold War in 1991, seemingly held great promise for Africa. However, in recent years, many elections in Africa have consistently become a source of violence. Electoral violence is threatening to become an intractable source of conflict on the African continent, making it hard for emerging democracies to consolidate their status as free democratic societies. Many remain largely autocratic or semi-democratic. African leaders are all too often not ready to relinquish political power, while political elites are ‘power hungry’ and use violence to skew the outcomes of elections in their favour. Hence, electoral violence is employed in order to manipulate civilian election choices and outcomes. Election violence is often deliberately used to target civilians, and in countries like Kenya involves inter-ethnic clashes. These “new wars” are fought unconventionally using ‘crude weapons’, (Kaldor 2013). Kaldor describes how these ‘new wars’ are fought as intra-state (within the state) wars in developing countries. Often, they are waged via state or county networks based on identity or ethnicity. The consequences of electoral violence include the destruction of property, reversed development, injuries, rape, death, internally displaced persons and refugees. Electoral violence persists despite attempts to contain it and measures to effectively manage these processes often prove to be inadequate. The study utilises an exploratory case study of Kenya during 2007-2008 Post-Election violence. The causes, the immediate steps that were initiated to mitigate violence and the reforms undertaken to generate peace structures and prevent future occurrences of post-election violence were explored. Forty-five participants representing involved citizens, negotiators and mediators were interviewed. The research was triangulated via the interview process, together with the use of primary document analysis and an extensive review of the literature. The data was analysed via the use of grounded theory. The research findings reveal that the causes of electoral violence are multi-faceted and multi-layered, with deep underlying issues. The causes include weak institutions, corruption, a non-representational electoral system, ethnicity and ethnic militia. Further causes include statelessness as experienced by certain groups, abuse of state resources and human rights violations. The role of political elites who withhold crucial information, thus denying the public the opportunity to make informed choices during elections was also found to contribute to electoral violence. Other information-related causes include biased media and sensational reporting. Findings also show that socio-economic issues such as poverty, unemployment, scarce resources and unmet basic human needs cannot be underestimated. Lastly, the causes of electoral violence included diverse interests of internal and external actors at play during elections. The findings revealed that although the Kenyan mediation process included the signing of a peace agreement, the root causes of electoral violence such as corruption, weak institutions, abuse of state resources and the unjust electoral system were not adequately addressed. A model for mediation for electoral violence which was explored and developed sought to build on the strengths of the Kenyan mediation process and address its inherent weaknesses, thus making this a significant contribution flowing from the study. The election model for mediation proposes certain key phases which include a pre-mediation process that will ensure a cessation of all hostilities; the mapping of the root causes of electoral violence and electoral reforms that provide resolutions that are acceptable to all the parties. Training of personnel at all levels of government to implement these reforms is also proposed. These measures can ensure the integrity and independence of electoral institutions from political manipulation. Training constitutes a crucial stage in the process of consolidating the emerging democracies. The model for mediation developed is therefore not only meant to mitigate electoral violence but is also intended to serve as a preventive measure. Many African states currently experience structural weaknesses similar to those that existed in Kenya before the 2007-2008 elections (and still persist). These fault lines include corruption, weak institutions, human rights violations, and lack of information. The proposed model for mediation which aims to counter these problems can thus be applied and adapted for implementation in Africa and globally. Several recommendations with implications for policy development are proposed to curb electoral violence. They include constitutional reforms, training of government and electoral officials and the introduction of a properly representational election system. This study, which focuses specifically on post-election violence, recommends further research investigating the pre-election phase, and ‘voting day’ causes of electoral violence for a more comprehensive approach to electoral violence research.

The role of political elites who withhold crucial information, thus denying the public the opportunity to make informed choices during elections was also found to contribute to electoral violence. Other information-related causes include biased media and sensational reporting. Findings also show that socio-economic issues such as poverty, unemployment, scarce resources and unmet basic human needs cannot be underestimated. Lastly, the causes of electoral violence included diverse interests of internal and external actors at play during elections. The findings revealed that although the Kenyan mediation process included the signing of a peace agreement, the root causes of electoral violence such as corruption, weak institutions, abuse of state resources and the unjust electoral system were not adequately addressed. A model for mediation for electoral violence which was explored and developed sought to build on the strengths of the Kenyan mediation process and address its inherent weaknesses, thus making this a significant contribution flowing from the study. The election model for mediation proposes certain key phases which include a pre-mediation process that will ensure a cessation of all hostilities; the mapping of the root causes of electoral violence and electoral reforms that provide resolutions that are acceptable to all the parties. Training of personnel at all levels of government to implement these reforms is also proposed. These measures can ensure the integrity and independence of electoral institutions from political manipulation. Training constitutes a crucial stage in the process of consolidating the emerging democracies. The model for mediation developed is therefore not only meant to mitigate electoral violence but is also intended to serve as a preventive measure. Many African states currently experience structural weaknesses similar to those that existed in Kenya before the 2007-2008 elections (and still persist). These fault lines include corruption, weak institutions, human rights violations, and lack of information. The proposed model for mediation which aims to counter these problems can thus be applied and adapted for implementation in Africa and globally. Several recommendations with implications for policy development are proposed to curb electoral violence. They include constitutional reforms, training of government and electoral officials and the introduction of a properly representational election system. This study, which focuses specifically on post-election violence, recommends further research investigating the pre-election phase, and ‘voting day’ causes of electoral violence for a more comprehensive approach to electoral violence research.

- Description: Waterbirds are often overlooked as predators in aquatic ecosystems, despite the fact that waterbirds congregate in great numbers in and around waterways, notably estuaries. To fully appreciate the effect that aquatic feeding waterbird species may have on aquatic prey communities and the role that they play in estuarine food webs, stable isotopes and fatty acid profiles were employed to examine the seasonal diet of selected waterbirds in the Kowie Estuary, Eastern Cape Province, South Africa. Population counts were conducted every month for four seasons to examine the demography of waterbirds in the lower reaches of the estuary. The mean monthly energy consumption, along with dry matter intake of all waterbird species observed, were calculated and compared to similar estuaries in South Africa and elsewhere. Three duck species, one migrant sandpiper and one piscivore were selected for more detailed investigation at several temporal scales. This thesis has revealed that stable isotope analysis of waterbird tissues provides more informative data than fatty acid analysis for investigating waterbird diet and basal resource-tertiary consumer nutrient coupling. Stable δ15N and δ13C isotopes from several body tissues, in conjunction with SIAR models, were used to determine the seasonal diet of each waterbird species, while fatty acid profiles were investigated to examine the trophic transfer of fatty acids from basal resources to waterbird predators via the benthic fauna. Stable isotopes revealed that Cape Shoveller, Cape Teal and Yellow-Billed Duck shifted their diet over both long and short temporal scales, while the migratory Ruff and piscivorous Little Egret maintained a relatively consistent diet over time. Isopods, amphipods, copepods and Mysidacea were the main foods of all three duck species and the Ruff (>30%). Little Egret fed mainly on flathead mullet throughout the year. Fatty acid analysis revealed evidence for trophic transfer of specific fatty acids from basal resources to waterbirds in the Kowie Estuary but provided little information on seasonal diet of waterbirds. Waterbirds foraging in the Kowie Estuary appeared to shift their diet to coincide with resource abundance pulses, but also displayed seasonal dietary overlap. This study highlights the role that waterbirds play in aquatic food webs. The subject requires more attention so that we can better understand all the predatory drivers on aquatic communities.

- Description: The aim of this study is to illustrate how, in the design of costumes, adopting design elements used to produce conceptual fashion can create conceptual costumes that have the ability to express emotions. The play Sounds of South End (2013) contains such qualities; therefore it has been selected to illustrate how the mood and emotional trajectory of a play can be interpreted through symbolism. The play illustrates the life before and after the forced removals during the apartheid (1960s and 1970s), of a fictional family, the Dietrichs, who live in South End, a suburb in Port Elizabeth, South Africa. A focus on the nature of emotional changes experienced by the family has been used to determine the overall mood of the play, leading to a translation of the shifting mood through a collection of conceptual costumes. The final collection was exhibited as an installation artwork that is an interpretation of the altering moods and emotions that occur in the life of the Dietrich family as the play unfolds. The conceptual costumes have been constructed to imbue the narrative of the play with deep meaning by using symbolic elements, such as colour, texture and weight, to suggest the emotional trajectory within the play. The eight costumes portray the interrelated gradual decline and resultant deterioration of human relations experienced by the Dietrichs, from a contented state of harmonious living to a wounded state of despair.

- Description: This treatise focuses on the design of a Water Sports Centre in the sporting precinct of Newlands in Cape Town. The building is concerned with the redevelopment of an existing facility that is underutilised and outdated, compared to the 21st-century sporting arena. The purpose of this treatise is to investigate the processes and issues involved in the design of a Water Sports Centre that is located in a public park environment, and to better understand the contextual, spatial, physical, and theoretical influences on the nature of such a project’s architectural resolution. The process begins with an analysis of the two separate typologies, namely, water sports centres and sports stadiums, to better understand the spatial and physical nature of the combined building types. Various precedents are investigated of which the materiality and physical nature of the buildings are uncovered to identify an appropriate architectural language. Moreover, the spatial nature of these buildings are divided into categories of which the inter-relationships are analysed. The nature of the site is then investigated to identify and develop constraints and design informants. The site-defining elements are analysed individually, and a corresponding set of issues is established through the study of particular precedents. With an understanding of the physical and spatial attributes of the typology, combined with an appropriate response to the site, the design resolution for the Water Sports Centre in the Newlands sporting precinct is presented.

- Description: On 24 July 2016, the Nelson Mandela Metropolitan University (NMMU) announced formal state approval to establish a new medical school. This treatise proposes the design of the medical faculty for NMMU. This medical faculty will challenge the typical school typology by the application of Biophilic design principles. This is achieved by critically engaging with the nature of a medical faculty and campus and by examining the context in which the proposal takes place. By means of a typological investigation, Livingstone Hospital in Port Elizabeth was deemed the most suitable location for the medical faculty. Through the integration of the programmatic requirements, technical strategy and the model of Biophilia, which stimulates the physiological needs and neurological functions of the users, the treatise successfully established a new precedent for medical school design in South Africa. The investigation of Livingstone Hospital highlighted the need for rehabilitation of the adjacent green structures and the campus as a whole. The design provides the “stent” which will fuse these entities, healing not only the physical campus but the users of the campus, the surrounding landscape and ultimately the adjacent precinct. The introduction of a medical faculty to the Health Sciences Department of NMMU in Port Elizabeth will breathe new life into the medical industry, unclogging the arteries which restrict the provision of healthcare for South African citizens.

- Description: There are many examples of cryptic species that have been identified through DNA-barcoding or other genetic techniques. There are, however, very few confirmations of cryptic species being reproductively isolated. This study presents one of the few cases of cryptic species that has been confirmed to be reproductively isolated and therefore true species according to the biological species concept. The cryptic species are of special interest because they were discovered within biological control agent populations. Two geographically isolated populations of Eccritotarsus catarinensis (Carvalho) [Hemiptera: Miridae], a biological control agent for the invasive aquatic macrophyte, water hyacinth, Eichhornia crassipes (Mart.) Solms [Pontederiaceae], in South Africa, were sampled from the native range of the species in South America. Morphological characteristics indicated that both populations were the same species according to the current taxonomy, but subsequent DNA analysis and breeding experiments revealed that the two populations are reproductively isolated. Crossbreeding experiments resulted in very few hybrid offspring when individuals were forced to interbreed with individuals of the other population, and no hybrid offspring were recorded when a choice of mate from either population was offered. The data indicate that the two populations are cryptic species that are reproductively incompatible. Subtle but reliable diagnostic characteristics were then identified to distinguish between the two species which would have been considered intraspecific variation without the data from the genetics and interbreeding experiments. These findings suggest that all consignments of biological control agents from allopatric populations should be screened for cryptic species using genetic techniques and that the importation of multiple consignments of the same species for biological control should be conducted with caution.

The conceptual framework of this study is located within African epistemology focusing on indigenous knowledge systems (IKS) in South Africa. The study aimed at enabling young amaXhosa men who had undergone TMI to reflect on their first-hand, personal accounts of Ulwa/ukokwa Xhosa and manhood. Six semistructured interviews and a follow up focus group discussion were held with 23-27 years old amaXhosa men residing in Joza Township in Grahamstown, Eastern Cape. Participants were identified through purposive sampling. The thesis reports on the following findings: (a) the significance of the place/location of initiation, and the guise of modernity; (b) feelings of anticipation experienced by the young men; (c) the theme on ubudoda(manhood) affirmation Ndiyindoda!; (d) the theme on the concealment of pain (perseverance); (e) the theme on respect for self and others and ubuntu;(f) Uzimelegeqe (independence and autonomy) and (g) social role and responsibility. The paper argues for the relevance of TMI as a significantrite of passage from boyhood to manhood among amaXhosa men.

- Description: Research into the benefits that ecosystems contribute to human wellbeing has multiplied over the last few years following from the seminal contributions of the international Millennium Ecosystem Assessment. In comparison, the fact that some ecosystem goods and services undermine or harm human wellbeing has been seriously overlooked. These negative impacts have become known as ecosystem disservices. The neglect of ecosystem disservices is problematic because investments into the management or reduction of ecosystem disservices may yield better outcomes for human wellbeing, or at a lower investment, than management of ecosystem services. Additionally, management to optimise specific ecosystem services may simultaneously exacerbate associated disservices. We posit that one reason for the neglect of ecosystem disservices from the discourse and policy debates around ecosystems and human wellbeing is because there is no widely accepted definition or typology of ecosystem disservices. Here, we briefly examine current understandings of the term ecosystem disservices and offer a definition and a working typology to help generate debate, policy and management options around ecosystem disservices. We differentiate ecosystem disservices from natural hazards and social hazards, consider some of their inherent properties and then classify them into six categories. A variety of examples are used to illustrate the different types of, and management strategies to, ecosystem disservices.

Ways of seeing over time: the construction and imagination of ‘historic separation’ in Israeli and Palestinian cultures

- Description: There exists an international consensus that Palestinian and Israeli societies are ceaselessly and essentially acrimonious. This thesis argues that the conceptualisation of ‘historic separation’ in Palestine/Israel is supported and nourished by national narratives that follow classic historicism and a linear trajectory of essentialised culture progressing over time. Given these patterns in historiography and cultural expressions, conceptualisations of the future are argued to be dominated by the ‘overdetermined’ and ‘sacralised’ pasts that arrest the ability to conceive of alternative horizons. These national narratives are analysed borrowing from the theorisation of Edward Said on hegemonic culture, and Ranjit Guha’s Subaltern critique of historicism. Zionism is argued to function as a cultural hegemony that operates in a mercurial, selfsustaining and vibrant manner that has the effect of what this thesis terms ‘centrifugal magnetism’ on discourse in the region. Palestinian national narratives are held to be in tangential relation to Zionism (a classic colonial master-narrative), thus entering into a ‘terrible embrace’ of destructive colonial/postcolonial repetition that tends towards violent conflict and the discrimination of minorities. This thesis then proposes a ‘way out’ of this historiographical pattern that is argued to tangibly inform the cultural fabric of the region. By drawing on the later works of Mahmoud Darwish, Mustaffa Hallaj and Said, it is proposed that there are traces of a notion of self and community that can be described as postnational. This demands a reconstruction of narratives of the past in the region in a pluralistic fashion that is based upon shared exilic identity in flux over what Darwish termed an ‘open historical space’. Crucially, this alternative postnational narrative opens up conceptualisations of the future and is founded upon a renewed disposition to temporality. This thesis thus concludes by proposing that an understanding of temporality as ‘ecstatic’ and essential to being (Martin Heidegger) should be included as a crucial consideration for the end to conflict and the attainment of just and equitable futures.

- Description: There exists an international consensus that Palestinian and Israeli societies are ceaselessly and essentially acrimonious. This thesis argues that the conceptualisation of ‘historic separation’ in Palestine/Israel is supported and nourished by national narratives that follow classic historicism and a linear trajectory of essentialised culture progressing over time. Given these patterns in historiography and cultural expressions, conceptualisations of the future are argued to be dominated by the ‘overdetermined’ and ‘sacralised’ pasts that arrest the ability to conceive of alternative horizons. These national narratives are analysed borrowing from the theorisation of Edward Said on hegemonic culture, and Ranjit Guha’s Subaltern critique of historicism. Zionism is argued to function as a cultural hegemony that operates in a mercurial, selfsustaining and vibrant manner that has the effect of what this thesis terms ‘centrifugal magnetism’ on discourse in the region. Palestinian national narratives are held to be in tangential relation to Zionism (a classic colonial master-narrative), thus entering into a ‘terrible embrace’ of destructive colonial/postcolonial repetition that tends towards violent conflict and the discrimination of minorities. This thesis then proposes a ‘way out’ of this historiographical pattern that is argued to tangibly inform the cultural fabric of the region. By drawing on the later works of Mahmoud Darwish, Mustaffa Hallaj and Said, it is proposed that there are traces of a notion of self and community that can be described as postnational. This demands a reconstruction of narratives of the past in the region in a pluralistic fashion that is based upon shared exilic identity in flux over what Darwish termed an ‘open historical space’. Crucially, this alternative postnational narrative opens up conceptualisations of the future and is founded upon a renewed disposition to temporality. This thesis thus concludes by proposing that an understanding of temporality as ‘ecstatic’ and essential to being (Martin Heidegger) should be included as a crucial consideration for the end to conflict and the attainment of just and equitable futures.

- Description: My collection of stories explores the intersection of the human body and the body of text via the tropes of disease and animality. Drawing on my experience of living with tuberculosis for many years, I attempt to write disease differently – not merely to be survived, overcome, cured, eradicated, but as something to be embraced via the Deleuzian affirmation of being worthy of what happens to us. Taking my cue from Sontag, I use a creaturely approach to writing, “an infinitely varied register of forms and tonalities for transporting the human voice into prose narrative”, emphasising the shared embodiedness of humans and animals so as to challenge the omnipotence of thought that subjugates and colonises the body as exclusively human.
