- Description: Although the concept of Bring Your Own Device (BYOD) was only first introduced in 2009, organisations and higher education institutions have shown an increasing interest in and tolerance for employees and students using their own mobile devices for work and academic purposes, to such an extent that it is predicted that BYOD will become the leading practice for all educational environments by the year 2017. Although mobile device usage is increasing in higher education institutions, it has been found that currently no generally recognised framework exists to aid South African higher education institutions with the implementation of BYOD. The problem is further worsened as research suggests that the number of new mobile vulnerabilities reported each year has increased. The primary objective of this study is to develop a framework for implementing BYOD in higher education institutions in South Africa. This primary objective is divided into several secondary objectives, which collectively aim to address the proposed problem. Therefore, the secondary objectives are to understand BYOD in organisations and the challenges it brings; to determine how BYOD challenges differ in higher education institutions; to determine the key components for implementing BYOD in higher education institutions; to determine the extent to which the BYOD key components relate to a higher education institution in South Africa; and to validate the proposed BYOD framework, verifying its quality, efficacy and utility. At first, a comprehensive literature study is used to determine and understand the benefits, challenges and key components for the implementation of BYOD in both organisations and higher education institutions. Thereafter, a case study is used to determine the extent to which the components, identified in the literature study, relate to an educational institution in South Africa. The findings from the case study, in combination with the key components, are then triangulated and a preliminary framework for implementing BYOD in higher education institutions in South Africa is argued. Furthermore, elite interviews are used to determine the quality, efficacy and utility of the proposed BYOD framework. To address the proposed problem, this research proposes a stepby- step holistic framework to aid South African higher education institutions with the implementation of BYOD. This framework adds a significant contribution to the work on this topic, as it provides a foundation upon which further such research can build. It is believed that such a framework would be useful for higher education institutions in South Africa and would result in the improved implementation of BYOD.

- Description: Accelerated soil erosion holds strong links to excessive land degradation, socioeconomic problems and accelerated climate change, particularly in developing countries such as South Africa. An analysis of the properties of severely eroded soils is undertaken to determine which characteristic properties influence the erodibility of the soils at several gully and badland sites in three catchments of the Ngqushwa rural municipality, which is tagged as one of the area’s most severely affected by soil erosion and degradation in the Eastern Cape. Physical, biological and chemical properties of the soils were analysed, including aggregate stability, soil texture, organic matter- and carbon content, clay mineralogy, sesquioxide content as Fe2O3 and cation composition. The distribution of a number of these properties was also determined, particularly between erosion sites, along hillslope profiles and with depth. The study area comprises three catchments, namely Mgwalana, Bira and Gqora which share common soil parent materials, land use history, exhibit similar topography and advanced degree of erosion. A total of 63 soil samples were strategically collected from identified erosion zones and site controls devoid of active erosion; where stability was evident by means of vegetation cover and soil surface condition. Surface samples were collected above 30cm depth and subsurface samples at depths greater than 30cm. To determine the fate of carbon additional samples were collected from runon and sink zones at the Mgwalana catchment along a transect from top to bottom slope. Laboratory analyses was performed to determine the soil properties, whereby C content was measured by the dry combustion method, Fe2O3- and cation content by Atomic Absorption (AA) Spectrometer, texture by the separation method described by Schlichting, Blume & Stahr (1995), clay mineralogy by X-Ray Diffraction and organic matter content by conversion of total C. In addition to these properties being used to infer aggregate stability, the wet sieving method was also used for this purpose and for validation of the other soil properties. The results revealed that no one soil property has a greater influence on aggregate stability than the others, but rather that the stability of the soil is dependent on the combinations of these properties in the soil and the interactions that occur between them. Based on this, the results indicated greater stability for runon, sink and control samples, mainly in the topsoil, which were characterised by a relatively higher C- and organic matter content, loam texture and higher concentrations of Ca2+. Furthermore, the less stable eroded samples were characterised by a more clay rich texture particularly in the subsoil, relatively lower C- and organic matter contents and a greater sodicity due to higher concentrations of Na+. The least stable soils belonged to the Gqora catchment, which were found to consist of higher silt content in the topsoil and a higher Fe2O3 content in the subsoil. The clay mineralogy was relatively uniform across all catchments, comprising of primarily illite and secondly kaolinite. The sample with the highest sodicity in terms of ESP contained smectite clay in addition to illite and kaolinite which is assumed to contribute to this increased Na+ concentration. These findings aid in the conclusion that the chemical characteristics of the soils, in association with biological and, to a less extent, physical properties of the soil exacerbate the erosion problem initiated by the extrinsic contributors, such as climate and topography. Investigation into the fate of carbon on eroded lands revealed a topographically driven dynamic whereby the total carbon content was found to be greater at the top and middle slope positions as well as in the sink zone. These hillslope sections were found to have a lower slope gradient and slightly more pronounced concave shape to those sections with lower C values. These topographic variables influence the degree of gully erosion taking place at different hillslope sections, which tends to be greater where slope angle is increased and convexity exists, resulting in the removal of soil C at these positions and its deposition in areas of accumulation, namely the runon and sink zones of low angle concave slope sections. The findings of this research may be used to develop restoration and management strategies with the ultimate goal to reduce the soils vulnerability to erosion by enhancing those soil properties conducive to greater aggregate stability as determined in the present study.

- Description: Focusing on four early works, then three from his middle period and three from the 1890s, this dissertation explores Meredith’s role as a novelist in the unfolding of a social and literary paradox, namely, that with the death of George Eliot in 1880, the dominant writers of fiction were male, and this remained the case until the advent of Virginia Woolf, while at the same time the woman’s movement for emancipation in all spheres of life—domestic, commercial, professional and political—was gathering in strength and conviction. None of the late nineteenth-century male novelists—James, Hardy, Moore and Gissing, as well as Meredith—was ideologically committed to the feminist cause; in fact the very term ‘feminist’ did not begin to become current in England until the mid-1890s. But they were all interested in one aspect or another of the ‘Woman Question’, even if James was ambivalent about female emancipation, and Gissing, on the whole, was somewhat hostile. Of all these novelists, it was Meredith whose work, especially in its last two decades, most copiously reveals a profound sympathy for women and their struggles to realize their desires and ambitions, both inside and outside the home, in a patriarchal world. The dissertation therefore concentrates on his presentation of his heroines in their relationships with the men who, in one way or another, dominate them, and with whom they must negotiate, within the social and sexual conventions of the time, a modus vivendi—a procedure that will entail, especially in the later work, some transgression of those conventions. Chapter 1 sketches more than two centuries of development in female consciousness of severe social disadvantage, from literary observations in the mid-seventeenth century to the intensifying of political representations in the writings of Mary Wollstonecraft, and the rise of the woman’s movement in the course of the Victorian century. The chapter includes an account of the impact on Meredith of John Stuart Mill’s The Subjection of Women (1869), and an examination of some of his female friendships by way of illuminating the experiential component of his insights into the ‘Woman Question’ as reflected in his fiction and letters. His unhappy first marriage is reserved for consideration in Chapter 2, as background to the discussion of The Ordeal of Richard Feverel (1859). This early novel, Meredith’s first in the realist mode, is widely accepted as being of high quality, and is given extended treatment, together with briefer accounts of three other early works, The Shaving of Shagpat (1855), Evan Harrington (1861), and Rhoda Fleming (1865), and one from Meredith’s middle period, Beauchamp’s Career (1876). Two more novels of this period, The Egoist (1879) and Diana of the Crossways (1885), are generally considered to be among his best works, and their heroines are given chapters to themselves (3 and 4). Chapter 5 provides further contextualization for the changing socio-political circumstances of the 1880s and 1890s, with particular reference to that heightening of feminist consciousness represented by the short-lived ‘New Woman’ phenomenon, to which Diana of the Crossways had been considered by some to be a contribution. Brief discussion of some other ‘New Woman’ novels of the 80s and 90s follows, giving literary context to the heroines of Meredith’s three late candidates in the genre, One of Our Conquerors (1891), Lord Ormont and His Aminta (1894), and The Amazing Marriage (1895). The dissertation concludes with a glance at Meredith’s influence on a few early twentieth-century novelists.
