The missionary work of the first Anglican Bishop of Natal, the Rt. Reverend John William Colenso, between the years 1852-1873
- Authors: Burnett, B B

- Description: At the outset it had been my intention to make only the slightest of references to the Church Controversy in which Bishop Colenso was involved and to have touched only lightly on his theological position. Apart from anything else I hesitated to enter the arena in which so many had already collided violently and where my own prejudices might be enlisted on one side or the other. It became evident however that Colenso the Controversialist, the Theologian could not be dissociated from Colenso the missionary, without giving an inadequate, and even misleading history of his missionary activities. The Controversy had a serious and deleterious effect on his missionary work, and no estimate of the value of a missionary's labours would be valid without some consideration of his teaching, more especially when his orthodoxy is suspect. I have therefore dealt as briefly as I could with these questions in Chapter V because of their relevance, and because to produce a work on an ecclesiastic without some reference to his tenets would be like writing a biography of Louis Botha without any allusion to his political 'faith', or of Wellington, without any mention of Waterloo. it would represent a distortion of history to write about a Missionary Bishop as though he were an amateur politician, or of a missionary as though he were interested only in finance and administration.

- Description: The area studied at Fern Kloof, near Grahamstown, consists of a strip of vegetation approximately 260 yds. long and 50 yds. wide, in which there are two communities: 1) indigenous forest 2) exotic Pine forest (which has only one tree species Pinus pinaster). Throughout the thesis this species is referred to as the pine. The object of the investigation has been to determine whether these communities are natural or not. This has involved a study of the floristic composition, the life forms and the structure of the plant communities. In addition, various soil and environmental factors have been studied.

Challenges and opportunities: an evaluation of the implementation of gender mainstreaming in South African government departments, with specific reference to the department of justice and constitutional development (DoJ&CD) and the department of foreign affairs (DFA)

- Description: The aim of this research project is to conduct an evaluation on the implementation of gender mainstreaming in South African government departments, with specific reference to the Department of Justice and Constitutional Development (DoJ&CD) and the Department of Foreign Affairs (DFA). The research project is based on the hypothesis that despite the existence of a National Gender Machinery, Gender Focal Points (GFPs) face numerous challenges in implementing gender mainstreaming, due to various internal and external factors. Based on the two case studies, the research project concludes that despite a strong commitment from government, GFPs still face challenges in effectively implementing gender mainstreaming. This is due to a lack of accountability, an understanding of the concept of gender mainstreaming, as well as a lack of resources. Furthermore, systemic weaknesses within the National Gender Machinery are exacerbating the challenges faced GFP

- Description: Global competition is forcing all organisations, both manufacturing and service or ientated, to review their facil ities and processes from a productivity and quality standpoint. The concept of lean manufacturing has evolved from mass production methodologies developed by Henry Ford. Lean methodology, as developed by the Toyota Motor Company of Japan, yields consistent product quality at a lower cost , while delivering greater variety to the customer. The purpose of this research was to identify lean methodology application to the service industr y and to evaluate its application to UTi South Africa (PTY) LTD. The research presented an empirical study of how a lean tool can be a ppl ied at UTi South Africa (PTY) LTD service operations and possible lean models for UTi Port Elizabeth. The research study found that lean methodology can be applied to the freight forwarding industry and that opportunities exist for lean to improve productivity.

On the Wiener index of bicyclic graphs and graphs with fixed segment sequence

- Language: English

- Description: Wiener index is defined as the sum of the distances between all unordered pairs of vertices in a graph. The study of the Wiener index is motivated by its application in chemistry. This thesis focuses on finding extremal bicyclic graphs relative to Wiener index under various conditions such as fixed circumference (length of the longest cycle) or fixed size of the core (maximal subgraph with no degree less than 2). A segment of a graph G is either a path whose end vertices have degree 1 or at least 3 in G and all the internal vertices have degree 2 in G, or a cycle where all the vertices have degree 2 in G except possibly one. The lengths of all the segments of G form it segment sequence. We also discuss extremal graphs with given segment sequence. , Thesis (MSc) -- Faculty of Science, Mathematics, 2021

- Description: Synthesis of fluorescent alloyed quantum dots (QDs) with unique optical properties suitable for a wide array of chemical, physical and biological applications is of research interest. In this work, highly luminescent and photostable alloyed quaternary CdSeTeS core QDs of two different sizes were fabricated via the organometallic hot-injection synthetic route. Characterization of the nanocrystals were performed using TEM, XRD, UV/vis and fluorescence spectrophotometric techniques. We have demonstrated in this work that the well fabricated alloyed quaternary CdSeTeS core QDs possess unique optical properties that are advantageous over conventional core/shell systems. Formation of the CdSeTeS/ZnS core/shell with the desired optical properties comes with a number of challenges, hence the advantages of the quaternary alloyed core over the core/shell QDs are (i) avoidance of the challenging process of determining the proper shell thickness which can provide the desired optical properties in the core/shell system and (ii) avoidance of the lattice-induced mismatch between the core and the shell material which can either lead to incomplete exciton confinement or dislocation at the core/shell interface.

- Description: Phishing attacks employ social engineering to target end-users, with the goal of stealing identifying or sensitive information. This information is used in activities such as identity theft or financial fraud. During a phishing campaign, attackers distribute URLs which; along with false information, point to fraudulent resources in an attempt to deceive users into requesting the resource. These URLs are made obscure through the use of several techniques which make automated detection difficult. Current methods used to detect malicious URLs face multiple problems which attackers use to their advantage. These problems include: the time required to react to new attacks; shifts in trends in URL obfuscation and usability problems caused by the latency incurred by the lookups required by these approaches. A new method of identifying malicious URLs using Artificial Neural Networks (ANNs) has been shown to be effective by several authors. The simple method of classification performed by ANNs result in very high classification speeds with little impact on usability. Samples used for the training, validation and testing of these ANNs are gathered from Phishtank and Open Directory. Words selected from the different sections of the samples are used to create a `Bag-of-Words (BOW)' which is used as a binary input vector indicating the presence of a word for a given sample. Twenty additional features which measure lexical attributes of the sample are used to increase classification accuracy. A framework that is capable of generating these classifiers in an automated fashion is implemented. These classifiers are automatically stored on a remote update distribution service which has been built to supply updates to classifier implementations. An example browser plugin is created and uses ANNs provided by this service. It is both capable of classifying URLs requested by a user in real time and is able to block these requests. The framework is tested in terms of training time and classification accuracy. Classification speed and the effectiveness of compression algorithms on the data required to distribute updates is tested. It is concluded that it is possible to generate these ANNs in a frequent fashion, and in a method that is small enough to distribute easily. It is also shown that classifications are made at high-speed with high-accuracy, resulting in little impact on usability.
