This study is an analysis of the effects of formaldehyde, a chemical which is both recombinogenic and mutagenic, on white-ivory (wi) a highly mutable allele of the white locus of Drosophila. Formaldehyde is shown to significantly increase the reversion frequency of wi. The results of this investigation differ from earlier observations in three respects: (1) there is a positive correlation between RNA (ribonucleic acid) concentration and reversion frequency in the presence of formaldehyde, but reversion does not appear to be totally RNA dependent; (2) female germ cells are more sensitive than those of the male; and ( 3) a cluster of revertants has been recovered. These indicate that formaldehyde-induced wi reversion may involve a different mechanism than that proposed for formaldehyde-induced sex-linked lethals. Different mechanisms have been proposed to account for the induction of sex-linked lethals and for the increase in recombination. Formaldehyde-induced reversion of white-ivory follows the parameters of recombination.

Thesis (M.Tech.: Homoeopathy)-Durban University of Technology, 2008. xiv, 222 leaves / A proving of ivory from the male African elephant (Loxodonta africana) 30CH was conducted. The proving symptoms were then analysed according to the doctrine of signatures, and compared to the proving symptoms of Lac Loxodonta africana. Aims and Objectives of the study The aim of this study was to identify the effects of ivory from male African elephant (Loxodonta africana) in a 30CH dilution, on healthy provers, and to record the clearly observable signs and symptoms produced by the provers, so as to determine the material medica of the proven substance. The objective of the study was to analyze the symptoms obtained from the proving according to the doctrine of signatures, and to establish any correlation that may exist between the homoeopathic drug picture produced and this doctrine. Methodology The remedy was derived from the tusk of a male african elephant (Loxodonta africana) and was prepared in accordance to the German Homeopathic Pharmacopoeia (Drishien, 2003:36-38). The remedy was dispensed in the form of six lactose powders. The research was conducted as a randomised, double blind placebo controlled study. A group of provers (26) that were carefully selected from the general public (Appendix A) were divided into two groups. Recruitment commenced by obtaining suitable provers through speaking to fellow homoeopathic students, as ii well as members of the general public. The researchers conducted interviews with potential provers, excluding those that did not meet the inclusion criteria (Appendix A). The provers were randomly divided into two groups, and instructed to begin recording in their journals a week before starting the remedy, and a week after taking the remedy. The provers continued to record all symptoms until the symptoms abated and continued recording after this time for another two weeks. Once the proving had been completed another full case history and physical exam was performed. Results After the results were collaborated the proving symptoms were then analysed according to the doctrine of signatures. The results of this proving indicated that Loxodonta africana has the potential to be a valuable remedy in homoeopathic practice. Proving signs and symptoms revealed that the remedy could be indicated for mental and emotional conditions as well as a variety of physical diseases. The results of this research confirmed the hypothesis that the proving of Loxodonta africana 30CH would produce clear observable signs and symptoms when administered to healthy individuals. The results of this research also confirmed the second hypothesis that a comparison would exist between the proving symptoms and a doctrine of signatures analysis. Conclusion Thus the proving of Loxodonta africana and the subsequent comparison to the doctrine of signatures has the potential to become a well utilised homoeopathic remedy.

Tourism has become an essential attribute of modern society that has an effect on the world and its citizens. On the other hand, tourism can also be blamed for an increase in environmental and social stress. Hence the need for a more sustainable tourism industry was advocated; thus the birth of alternative forms of tourism such as urban ecotourism, responsible tourism and community-based tourism. Urban ecotourism has been identified as a method of sustainable tourism that is expected to subsidise to both conservation and development in urban areas. This requires input and cooperation from various stakeholders. One of the most important stakeholders in this process is the local community. Thus, when there is collaboration with host communities in urban ecotourism projects, these projects convert to become community development. These projects such as urban parks are vital assets within the local community as they assist in addressing a broader range of environmental and societal issues. However, these instrumental resources are often ignored, resulting in a loss of potential benefits.

Ivory Coast covers an area of 124,000 square miles with reasonable rainfall for food crops production. But besides what has been called the economic "miracle," the country relies on increasing food imports (rice, wheat, meat, and milk products). At the same time, the country's earnings from the major export commodities are shrinking. So the primary objective was to identify the main causes and circumstances that have resulted in reductions in food production. The major hypothesis was that the present situation is simply the result of policies that have favored cash crops relative to good products. A formal treatment and an analysis of the institutional and structural setting were made. The results of the formal treatment showed relatively high trend growth rate in cash crops compared to good products. Some food crops experienced high trend growth rate but exhibited a very erratic pattern in their production. And this seems to support the hypothesis made. A ministry of Rural Development has been created in November, 1983, and increasing food production is one of its main objectives. However, profound and appropriate studies prior to any move towards total reliance on domestic food production are crucial for the country's resources allocation.

Student Number : 0415917E - MA research report - School of Social Sciences - Faculty of Humanities / The conceptualisation of Ivorian crisis as an ethnic conflict is misleading an strengthens Afro-pessimism. This study intends to show that by addressing issues of nationality and ethnicity, the Linas Marcoussis accord dealt woth symptoms rather than the disease of the Ivorian crisis. Moreover, the conflict has become a mode of accumulation. The conflict in Ivory Coast was ignited by contestation over resources. In other words, the conflict has its roots in the scarcity of resources and the absence or failure of institutions that guarantee equitable distribution. Taking cognisance of the fact that the lack of indigenous capital means control of the state is control of economic resources. Economic growth translated to political stability because the various demand-bearing groups were co-opted and rewarded. The advert of democratisation and economic crisis meant access to resources became hotly contested. Against this backdrop, ivoirite became a nationalistic rhetoric for political mobilisation in the absence of an economic alternative grounded in the contradictory nature of the Ivorian state.

This research investigated the instructional leadership roles of selected township principals. Its main focus was therefore to explore and understand the roles and practices engaged in by township principals in order to influence effective teaching and learning in their schools. A qualitative research method was used to conduct a case study with two schools. A total of six participants were purposefully sampled: two principals and four teachers. The data was collected using individual interviews, document analysis and observations. From the data, five themes emerged in this study. Although the findings revealed that there are some principals with a weak and partial understanding of what instructional leadership entails, these principals do put a remarkable effort into executing their instructional roles. Instructional leadership development programmes are necessary for all School Management Team (SMT) members. / Educational Leadership and Management / M. Ed. (Education Management)

The aim of this research was to evaluate the role of the first responder at the crime scene, focusing on visible policing members at Ivory Park Police Station situated in Gauteng Province. A qualitative approach was employed in which the multiple data sources of literature, documents (SAPS directives) and structured interviews were compared in an attempt to substantiate the research findings. The interviews were conducted with visible policing members who attended to crime scenes as first responders and with detective branch commanders. This research discussed a number of key concepts: crime scene, criminal investigation, first responder, Locard’s Principle and physical evidence. It explained that criminal investigation is a logical and systematic process of gathering, locating and collecting evidence and the subsequent apprehension of perpetrators of crime in an attempt to secure a conviction. The objectives of criminal investigation are to detect crime; locate and identify possible offenders; gather, collect and process evidence; arrest offenders; recover stolen property; and bring the perpetrators before court to secure a conviction. The basic purpose of investigation is to prevent crime. Locard’s Principle, also known as the “the contact theory”, is that every contact leaves a trace. This research also suggests the processes that must be followed when crime is reported, the meaning of preliminary investigation, and the basic considerations during preliminary investigation, the main mistakes made by the first responder and the solutions to the identified mistakes. It is imperative that visible policing members familiarise themselves with the purpose of investigation and develop an understanding of the term “Locard’s Principle”, the process that must be followed when crime is reported, the basic considerations in the preliminary investigation of a crime and the main mistakes made by the first responders at the scene of crime, as these carry significant weight in the execution of their daily duties. These must be understood by the first responder as they contribute to the successful investigation and prosecution of offenders. This research hopes to assist in securing convictions and decreasing the number of repeat offenders who commit crimes. / Criminology and Security Science / M.A. (Criminal Justice)

Humans’ hunting for ivory has had a serious impact of the African elephant population. Ivory has throughout history been a symbol of manhood and status. As the market of ivory expanded to the rest of the world, the market demand for ivory became higher than what the elephants could manage to provide. In the 1980’s, the African elephant population was threatened by extension and it was reduced with 50 percent in ten years. For this reason, CITES placed the African elephant population under a ban, which made it an illegal act to trade ivory and other elephant parts.
