The aim of the study was to investigate the impact of the intersection of race, gender and social class on women leaders’ work experience and career progression in order to come up with strategies for gender transformation at leadership level in corporate South Africa. The problem statement of this research study concerns the indication in the annual report of the Commission for Employment Equity (Department of Labour 2012) that there is under-representation of women, especially African and Coloured women, at top management level relative to the economically active population. The Women Empowerment and Gender Equality Bill was published in the Government Gazette No. 37005 of 6 November 2013. This Bill aims to enforce compliance with the stipulated minimum representation of women at senior levels in both the private and public sectors. This study, with its objective of reaching an understanding of the impact of the intersection of race, gender and social class on women’s career progression, is therefore timeous. Getting the perspective of woman CEOs across race and class on how to transform gender at leadership level could add an important voice to transformation and could be of benefit to decision makers in business and in government. Based on this problem statement the following research questions were formulated: - To what extent does the intersection of race, social class and gender impact on women CEOs’ experience in their work roles and career progression? - How might an understanding of women leaders’ experiences in their roles assist with strategies to transform gender at leadership level in corporate South Africa? Qualitative research methodology was chosen as the appropriate methodology and grounded theory was employed. Purposive, snowball and theoretical sampling methods were used to identify fourteen participants (13 CEOs and one chairman).The life story method was employed for in-depth semi-structured interviews from which rich descriptive data was collected and which was analysed using grounded theory. Findings confirmed that the intersection of race, gender, age and class does have an impact on women’s career progression and their life experiences. The dominant social identity was race for blacks and gender whites; class and age were the overlay. In terms of strategies for gender transformation, first-order constructs from the participants were related to abstract second-order constructs from the literature, which led to the formulation of the WHEEL Theoretical Model. The theoretical model is an integration of different elements required for the formulation of strategies for gender transformation at leadership level. The different elements were women themselves; domestic and family support; the organisation; society and government. Despite some limitations that were encountered, the aim of the study was achieved by making a contribution not only to the development of theory related to strategies for gender transformation at leadership level, which other scholars can build from, but also to the gaining of insights into the intersection of multiple social identities and their impact which can be used by business leaders and policymakers to address inequalities in organisations. In addition, this research study made various recommendations for future research / Business Management

The thesis deals with contact manifolds and their groups of transformations and relatedly with contact fibre bundles. We apply the framework of convenient calculus on in finite dimensional smooth manifolds to study the Chern-Weil theory of groups of strict contactomorphisms producing several non-vanishing type results on the cohomology of the classifying spaces of these groups. Moreover, we prove that the space of isocontact embeddings of one contact manifold to another can be given the structure of a smooth manifold and a principal bundle. Using this we describe a particular smooth model of the classifying space for the group Cont+(M; ) of (co-orientation preserving) contactomorphisms of a closed contact manifold (M; ). Lastly, we show that the standard action of the unitary group U(2) on the standard contact 3-sphere S3 induces a homotopy equivalence Cont+(S3; std) ' U(2).

Concern over excess phosphorus (P) input and loading in some soils of the Canadian prairie region has led to a need for a better understanding of the fate of added manure and fertilizer P. Information on the effects of manure application over long term (i.e., years) and short term (i.e., weeks, months) as related to management practices and manure form is still lacking. Knowledge of the P forms and species present in soil following application of manure and inorganic P fertilizers, and linking this to potential P availability and mobility is needed to make sound P management recommendations. The objective of this thesis project was to assess the speciation of soil P in different manures and inorganic fertilizer-amended Saskatchewan soils as affected by time, presence and absence of plants, landscape position, soil type, and management practices including rate and placement. Three studies were conducted (growth chamber and field-based experiments) to study P behavior in soils. These studies closely followed a time scale, beginning with speciation and fate followed over the very short-term (i.e., days to weeks) to a short-term period (i.e., months to a year) following amendment application, and finally the effects of repeated annual manure additions made over the long term (i.e., 11 years). Soils used in this study were loamy textured Brown and Black Chernozems. Solid cattle manure (SCM) and liquid hog manure (LHM) were applied at low and high rates in the very short-term and long-term studies. The low rate of SCM and LHM application was 7.6 T ha-1 yr-1 (dry weight) and 37,000 L ha-1 yr-1, respectively which was equivalent to approximately 100 kg total N ha-1 yr-1 application (agronomic N rate). The high rate was four times this amount. Inorganic fertilizer (mono-ammonium phosphate blended with urea) at rate of 54 kg N ha-1 and 12 kg P ha-1 and SCM at rate of 60 T ha-1 were applied in the short-term study. A sequential chemical extraction procedure was used to fractionate P in very short-term and short-term studies and different soil test phosphorus (STP) methods were used to determine effects on the labile P in the long-term study. Changes in P speciation with time and their relative proportions in fertilizered soils were also assessed using the synchrotron-based X-ray absorption near-edge structure (XANES) spectroscopy in all studies. This study has revealed that manure, especially SCM elevates labile P over all time frames examined. Over the very short-term (i.e., weeks to a month), P was added as manure tends to remain in labile forms like brushite and adsorbed P that is accessible to plants for uptake. In the manure band (months to a year), manure P was relatively unchanged over a period of months while in the mono-ammonium phosphate (MAP) fertilizer band, adsorbed and Ca-P was readily formed from fertilizer P. Aging over several years (one to eleven years), along with high soil pH and high Ca:P ratio enhanced formation of more stable Ca-P minerals like apatite, especially in SCM amended soil. Overall, the unique combined use of wet chemical analysis and synchrotron-based techniques in this thesis research has improved our understanding of fate and transformation of P added to prairie soils. It is suggested that future studies of fate of applied P in soil also utilize a combination of wet chemical and spectroscopic techniques, as this was shown to be a rewarding approach.

Nigeria, the most populous country in Africa, is bedevilled with various conflicts which have been exacerbated by the multiplicity and diversity which characterize the nation. The country is a multi-ethnic, multicultural, multiregional and multi-religious society. And while such arrays of features are not peculiar to Nigeria, managing them has greatly propped up various conflicts, with religious conflict emerging as one of the most devastating of all. It would appear as though, more than any other single issue, religious conflict has become a threat to national cohesion, stability and development. It has led to fears, suspicions, unrest; mass displacement of people, destruction of lives and property; consequently leading to major set-backs for nation building. The three main religions of Nigeria are the Indigenous Religions, Islam and Christianity, with Islam and Christianity having almost equal strength of adherence. While the indigenous religions have generally been tolerant and accommodating of the two “guest” religions, contestations and incessant violent clashes have characterized the relationship between Muslims and Christians, particularly in Northern Nigeria, and this has been on the increase in frequency, intensity and sophistication. This situation has led to the emergence and deployment of numerous approaches towards transforming conflicts in order to ensure peaceful co-existence of all the people. The task of this thesis is to contribute practical, theological reflections to the ongoing search for how Nigeria will end the undesired religious conflict between Muslims and Christians and build a peaceful and harmonious society. To do this, John Paul Lederach’s conceptual framework for conflict transformation was adopted and explained in chapter one; and two religious conflicts which took place in the Northern Nigerian cities of Jos and Maduguri were empirically investigated through intensive fieldwork. A review of relevant literature was carried out in chapter two and an elaborate explanation of the socio-scientific and theological methodologies adopted for the research was presented in the third chapter. In order to establish the causes, manifestations and consequences of the conflicts, chapter four and five explored their remote and root causes. Because this research is grounded on the assumption that religion is not just a source of conflict, but a resource for peace, and on the contribution of faiths to contemporary public debates, it provides a new approach which challenges the religious institutions, particularly the Church, through its pastoral ministry, to become actively involved in the transformation of conflict in the nation. The research holds that the greatest contribution of religion to the quest to transform religious conflict in Nigeria is through a practical theology which should be demonstrated in both spirituality and strategy. As such, and based on empirical findings from the zones of conflict, a theology of hospitality is suggested in chapter six, as a gradual but effective method of transforming relationships between Christians and Muslims in Nigeria. While the approach does not preclude other approaches, it offers the enormous resources, possibilities and opportunities, ingrained within the religious domain for conflict transformation in contemporary Nigerian society. The strategies for achieving the desired transformation of the situation of conflict on short and long-term basis through the theology of hospitality are suggested in the seventh chapter.
