Previous classifications of the Nepticulidae were based on species from the northern hemisphere, primarily western Europe (including the United Kingdom) and North America. The revised classification presented in the present work was developed from a study of material primarily from southern Africa, but also from Australia, Europe, North America, and the Orient. Most of the descriptive section deals with the taxonomy of the Nepticulidae of southern Africa. Nevertheless, a guide to the supraspecific classification of the family was a major aim. Cladistic methods were used to assess genealogy as far as possible. The degree to which it has been elucidated is incorporated into the classification. As a result of the study, the Nepticulidae are divided into two subfamilies. One of these subfamilies is divided into two tribes. Fifteen genera and six subgenera are recognised. Two keys are presented, one to subfamilies and tribes and the other to genera and subgenera. The species from southern Africa are included in eight genera, three of which are new. One hundred and seventeen species from southern Africa are considered. Seventy- two new species are described in this work. Of these 40 have been published and 32 appear as manuscript names. For some species described by previous workers lectotypes have been designated where appropriate. The primary types of all the known species from southern Africa have been examined. Observations on adult structure are discussed from the viewpoint of phylogenetic relationships both within the Nepticulidae and between the family and other lepidopteran groups. This has led to a re-interpretation and expansion of some aspects of nepticulid morphology. Numerical phenetic methods, which include cluster analyses and an ordination technique (principal component analysis), were used to check my personal assessment of phena. The illustrations (phenograms and ordination diagrams) provide a visual summary of phenetic relationships of as wide a range of Nepticulidae as possible. Aspects of the nature of taxonomic characters, ancestor-descendant relationships, and homoplasy are discussed. Brief comments are made on distribution, and host-plant choice and phylogeny.

There is a need to review and recast how space is being planned and how regulations are responding to the realities of the informal economy. Street trading provides a critical platform to explore the dynamics and complexity of planning and management of informal activities in public spaces. This research explored how city governance shapes the practices of informal street trading in Gaborone, Botswana. It investigated how street traders navigate their daily trading and their spatial practices and strategies. Insights were gleaned through in-depth interviews with street traders in three different sites in Gaboroneand key informant interviews with politicians and government officials–both senior and lower level staff. Combining the government officials'and traders' perspectives has allowed for the exploration of the disjuncture betweenthe two. The interview findings indicated that the state continues to govern but with inappropriate tools, and traders continue to trade but in sub-optimum ways. The Gaborone Council has made some headway in accepting street traders but still provides little or no infrastructure. It is argued that traders themselves constitute public space, so their voices, practices, strategies and resilience need to be understood. The dissertation concludes by making recommendations that could improve conditions for all parties.

The problem of informing appropriate architectural practice in southern Africa is addressed by proposing to divert analytical attention away from the level of appearances when researching the form of indigenous settlement patterns and architecture. By way of example, an empirical study of the homestead as a unit of settlement pattern in Ovamboland is undertaken by exploring the ways in which the designer/builders themselves perceive and value space with a view to identifying and describing the organizational structure of the homestead. The initial assumption is that this form of settlement, examined as a set of spatial relations, encodes within its organizational structure the formula (or diagram) for its reproduction. The hypothesis is that a relevant understanding of indigenous settlement and architecture can only be grasped if inquiry extends beyond the formal aspects of style and technology to include an analysis of its spatial characteristic; this being the external projection of the socio-economic pattern (or ideology) of the people that produce it. And, such analysis being useful in identifying the formula which, when it interacts with its context, reproduces the observed settlement form. In view of this, a method of study is proposed which attempts to describe and examine settlement space from 'within' by exploring all the physical and non-physical determinants of form. This is done by isolating each determinant as a specification of settlement from and thereby arranging it into a scheme based on the scale of space with which it deals. The conclusions are, firstly, that because the homesteads display similar features of layout and accommodation there must exist a common, agreed-upon diagram which ensures its constant reproduction. Secondly, the evidence for the diagram must lie within the way the designer/builders perceive homestead space. Thirdly, this perception has its roots in historically inherited and functionally derived values and uses of space. Finally, a preliminary diagram is proposed which, it is argued, needs to be verified by undertaking further investigations of a similar nature in other areas of southern Africa where indigenous people occupy space.

The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata biodiversity overall (161 spp.) is in the Austroriparian biotic province. The greatest degree of faunal similarity between the south-central U.S. and other intra-continental regions was observed for the eastern (64%) United States. Diversity is a function of area, and as expected, the numbers of breeding birds and Odonata, in each contiguous U.S. state are positively correlated (r=0.376, n=33, p=0.031). There is, however, no strong correlation between land area and species diversity within the region, but those natural biotic provinces (Austroriparian, Texan, Balconian) where aquatic systems and topographic heterogeneity are the greatest provide a broader spectrum of potential Odonata habitats and thus support a greater number of Odonata species.

Land ownership remains an important and contested issue in contemporary South African politics. Drawing inspiration from Hernando de Soto’s work, especially his book, The Mystery of Capital: Why Capitalism Triumphs in the West and Fails Everywhere Else (2000), which sees equitable and private land ownership as a key factor for economic growth and development, this thesis details South Africa’s own landed past in order to better understand its political present. Its central research question asks: What role did South Africa’s land and agricultural policies from 1860-1920 play in the country’s unequal development over time? This thesis traces historical transitions in land ownership patterns from the four weak and underdeveloped settler colonies (The Cape Colony, Natal, Orange Free State and the Zuid-Afrikaansche Republiek) to the rapidly industrialising, but racialised, South African state and the eventual emergence of white commercial farming by 1920. The thesis engages with a long heritage of South African historical writing on political economy as a central methodology, from its early liberal roots with W.M. Macmillan’s writings on rural poverty in the 1920s, to more radical, neo-Marxist writings of the 1970s and 1980s. This thesis argues that the racialised land and labour policies from 1860-1920 produced a white oligarchy of landowners, which led to an unequal distribution of wealth over time and following De Soto, therefore inhibited economic growth and development. The thesis ultimately speaks to the validity of De Soto’s work, as well as the importance of land and agricultural policies in South Africa today. / Dissertation (MScoSci (History))--University of Pretoria, 2020. / Andrew W.

>Doctor Literarum - DLit / This thesis suggests that there is an urgent need for academic work in literary and cultural studies to become more responsive to the contemporary eco-social crisis of environment and development. Questioning the sustainability of current practices, I introduce an approach which has emerged in the attempt to reorient my own work in English Studies towards what I call environmental literacy. My discussion consists of a prologue, six chapters, and an epilogue. The prologue is a story essay which presents through metaphor and narrative some of the questions which later chapters explore in more familiarly academic register. Chapters One and Two assemble the theoretical tools which have shaped my priorities. The first situates the project in terms of issues in South African eco-politics, and goes on to introduce potentially useful models in eco-criticism , environmental history, ecological philosophy and feminist theory. The second chapter argues that elements in Mahayana Buddhism (specifically teachings on emptiness and dependent arising and their relation to compassion) offer suggestive models for further radicalizing our theory I practice. The following degree chapters experiment with writing environmentally literate responses to several texts (one historical and the rest contemporary). Chapter Three is an appreciative reading of the representation of the Garden in William Blake's poem The Book of Thel (1789), Chapter Four brings personal narrative into an analysis of Gary Snyder's epic poem Mountains and Rivers Without End (1996), and Chapter Five is a critical survey of eco-cultural texts produced in South Africa during the period 1986- 1996. In Chapter Si.." I report on some of the pedagogical implications of thee orientation 1 have described , drawing on thee experience of teaching at the University of the Western Cape. The epilogue is brief and imagistic. The written text of the thesis is accompanied by pictures of people, plants and places.

The literary criticism of the so-called cult of Southern femininity in the fiction and drama of Southern writers is well established. However, there is little criticism regarding these figures in Southern poetry. In response to this gap in scholarship, this study examines the changing representations of the belle or lady in Southern poetry from the early nineteenth through the mid-twentieth century. She appears in poems written by white and African American men and women from three distinct historical and literary periods in the South: the antebellum period, the post-bellum period, and the twentieth century. This study examines the manner in which these different groups of poets in each period represent her. The overall trend of Southern poetry’s portrayal of women through these periods is that it moves from an idealized and mythical image in the antebellum period to a more realistic image in the twentieth century.

This research approach focused on 2x8 and 2x10 lumber sizes, in lengths ranging from 12- to 16t. Lumber sample data collection included: growth rings per inch (RPI), specific gravity (SG) and presence of pith. The lumber was tested in static bending per ASTM D 198. Small clear samples were then cut and used for compression testing using ASTM D 143. Lumber for this project was collected from retail lumber stores across the Southeastern United States. The larger 'host' study focused on generating current material property data from over 2000 southern pine boards to help establish more accurate and up to date lumber standards. The sampling, dubbed the 'production-weighted sampling' procedure, utilized in this study mimics the requirements of ASTM 1990. Moreover, the findings from this study are beneficial for industry and research communities alike as several smaller projects, including this one, highlight advances ranging from new lumber design values to non-destructive testing technique innovations evaluating wood. All data were analyzed using IBM SPSS version 25 software. Bivariate correlations were run in conjunction with linear regressions. Compression parallel to grain (C?) and compression perpendicular to grain (C?) were statistically tested with RPI, SG and the presence/absence of pith as independent variables. Initially, the independent variables were tested across all data for each lumber size. Then, a series of data segmentation techniques were employed among each of the independent variables: RPI, SG and pith presence. For RPI, the segments were categorized: less than 3 RPI, 3 to 5 RPI, and more than 5 RPI. Secondly, SG segments were developed in groups: less than 0.4, 0.4 to 0.5, more than 0.5. Lastly, the pith data were segmented: no pith, pith one end and pith both ends. Compression parallel and perpendicular to grain were not predictable by RPI, although the SG values by RPI segments did exhibit a stronger statistical relationship. The SG segments themselves did not reveal statistical significance; however, the pith segments yielded higher r2 values. For compression parallel to grain, r2 values were almost double than perpendicular to grain r2 values, across all pith segments and both lumber sizes.

This study compares the syntax of nineteenth-century Orange River Afrikaans with Dutch and synchronic Afrikaans varieties, with particular attention to Griqua Afrikaans. It provides an account of the differences that are found between the earliest attestations of an extraterritorial variety of the Dutch language on southern African soil (the so-called Cape Dutch Vernacular) with the present-day outcome. The data collected for this study originate chiefly from an hitherto undisclosed corpus of letters kept in the Namibian State Archives by the so-called Oorlam-Nama, people of mixed descent who lived on the periphery of the nineteenth- century Cape colonial society. This thesis argues that nineteenth-century Orange River Afrikaans is a representative continuation of the earliest developments in the linguistic contact situation that existed at the Cape. The thesis advances that literacy and social class are important factors in the assessment of the written record from the Dutch colony at the Cape. The thesis centers around the letters by one author, Jan Jonker Afrikaner, written over a period of nearly twenty years in the second half of the nineteenth century. This legacy is a unique contribution to the diachronic data concerning the development of Afrikaans. From the data it is shown that this author had the command over different registers, fluctuating between a near perfect metropolitan Dutch and a Hollands that is classified as basilectal Afrikaans. The comparison of the data is set in a framework inspired by the concepts put forward in Generative Grammar. This has precipitated an exciting linguistic comparison of contemporary Afrikaans grammar with the diachronic material. This dissertation challenges the idea that the Khoesan Languages were of no or little influence in the development of Afrikaans. The linguistic analysis of the nineteenth-century data reveal that the developments which took place cannot be attributed to one single origin. It is demonstrated that the innovations and change that can be identified run parallel to regular patterns that are found in other languages generally classified as creole languages. It is argued that the syntax of the Khoesan languages is a major reinforcing factor in the development of the syntactic idiosyncrasies that are identified as un-Germanic characteristics of Afrikaans. Limited to nonstandard varieties of Afrikaans, in the concluding sections the question is raised how these findings are to be addressed in the larger context of language change.
