- Description: Recent research has shown that it is possible to identify malicious URLs through lexical analysis of their URL structures alone. This paper intends to explore the effectiveness of these lightweight classification algorithms when working with large real world datasets including lists of malicious URLs obtained from Phishtank as well as largely filtered be-nign URLs obtained from proxy traffic logs. Lightweight algorithms are defined as methods by which URLs are analysed that do not use exter-nal sources of information such as WHOIS lookups, blacklist lookups and content analysis. These parameters include URL length, number of delimiters as well as the number of traversals through the directory structure and are used throughout much of the research in the para-digm of lightweight classification. Methods which include external sources of information are often called fully featured classifications and have been shown to be only slightly more effective than a purely lexical analysis when considering both false-positives and false-negatives. This distinction allows these algorithms to be run client side without the introduction of additional latency, but still providing a high level of accu-racy through the use of modern techniques in training classifiers. Anal-ysis of this type will also be useful in an incident response analysis where large numbers of URLs need to be filtered for potentially mali-cious URLs as an initial step in information gathering as well as end us-er implementations such as browser extensions which could help pro-tect the user from following potentially malicious links. Both AROW and CW classifier update methods will be used as prototype implementa-tions and their effectiveness will be compared to fully featured analysis results. These methods are interesting because they are able to train on any labelled data, including instances in which their prediction is cor-rect, allowing them to build a confidence in specific lexical features. This makes it possible for them to be trained using noisy input data, making them ideal for real world applications such as link filtering and information gathering.

- Description: Organised crime is a global phenomenon. It is a problem in South Africa as it is a problem in most countries. International and regional organisations, in particular, United Nations, Financial Action Task Force (FATF), and African Union (AU), have developed legislative measures and laid down minimum standards to assist party and non-party states to combat the scourge. Member countries and signatories to those instruments are ever encouraged to bring about national legislative and regulatory frameworks to criminalise predicate crimes, curb money laundering, confiscate instrumentalities and proceeds of such crimes, and to co-operate amongst themselves in their endeavours to fight the scourge. South Africa is a signatory and state party to the Vienna Convention, the Palermo Convention, African Union conventions, Southern African Development Community protocols, and has embraced Financial Action Task Force Forty Recommendations. As a signatory and a state party to these instruments, South Africa has passed, in its parliament, a vast array of legislative tools aimed at complimenting the criminalisation of organised crime related conduct (thus extending range of predicate crimes, and has also put in place preventative measures to be taken by financial, non-financial and professional institutions against money laundering practices, in order to deny organised criminals of illicit proceeds and a further use of property as an instrument of crime. The legislative framework is also aimed to foster international co-operation in the form of mutual assistance, extradition and enforcement of foreign judgements and sentences. There is a public perception, though, that crime pays in South Africa. The general public perception is that crime pays because the laws of the country always lag behind the ingenuity of organised criminals who, it is believed, are always a step or two ahead in better organisation of their nefarious activities and in the use of sophisticated methods of execution to achieve their goals. The objective of this research is to evaluate existing South African laws intended to deal with organised crime with relevant international instruments in order to establish whether the laws are adequate and are being implemented effectively to fight the scourge. The hypothesis of this research project is that South Africa has adequate laws (compliance); however, the problem lies in their implementation (enforcement). To obtain the necessary information to achieve the said objectives, the views made by various writers on organised crime were considered. The legislation currently in place to combat organised crime was identified and measured against aforementioned instruments in order to establish whether they do achieve the minimum standards set for the fight against organised crime. The comparison was done following the perspectives contained in these instruments in chapter form. In this regard, over-achievements as well as under-achievements were highlighted. For an example, article 6 of the Palermo convention instructs state parties to include as predicate offences all serious crime, punishable by maximum deprivation of liberty of at least 4 years or more, for money laundering. The Prevention of Organised Crime Act (POCA), on the other hand, contains no list of specific predicate offences, but makes an open-ended reference to the „proceeds of unlawful activities‟. It is, therefore, all-encompassing. Another example can be found in the South African definition of corruption. The South African statutory definition penalises corruption „in the widest sense and in all its forms, whereas that in the Palermo Convention is limited or restricted, as it does not instruct for the criminalisation of corruption involving foreign public officials or international civil servants. The evaluation of existing South African laws shows that South Africa has adequate laws to fight organised crime. There is, however, a room for improvement in their implementation, particularly in the prosecution of organised crimes. The South African government is urged to make available adequate financial resources to enable prosecutors to carry out their functions effectively in the fight against the scourge.

- Description: This study was aimed at evaluating the effectiveness of teaching practice as a context for the development of student teachers’ competences at Walter Sisulu University. The study was necessitated by the lack of information on whether teaching practice really provides an effective context or not. A literature study focusing on planning of teaching practice, preparation of student teachers for teaching practice, placement of student teachers for teaching practice, mentoring during teaching practice as well as supervision and assessment of teaching practice was conducted. The activity and situated learning theories provided a theoretical framework for studying teaching practice. The mixed-methods approach consisting of quantitative and qualitative approaches was used and data was collected through questionnaires and focus group discussions. The participants in the study were: thirty (30) student teachers in their third year of study; ten (10) host teachers who were hosting student teachers at the time of data collection for this study and ten (10) university supervisors responsible for teaching practice supervision. Data from closed-ended questionnaire items were analysed statistically. Frequencies and percentages were derived. Content analysis was used to analyse qualitative data. The results of the study revealed that there was a serious lack of communication between the university and the schools used for teaching practice and as a result student teachers were subjected to a wide range of treatment when they arrived at the schools. The findings also showed that student teachers were inadequately prepared for teaching practice. Student teachers were faced with serious challenges with regard to placement and there was no common programme of mentoring. The schools, as a result, did not provide a sufficiently-appropriate environment for teaching practice to become an effective context for student teachers‘ competence development. The recommendations made include suggestions for the improvement of the general organisation of teaching practice with the university and the schools working as partners in all the activities of teaching practice. The introduction of a formal programme for the preparation of student teachers for teaching practice is suggested and a teaching practice model is also proposed.

- Description: The context of this study centres on Higher Education in South Africa, the role that this sector plays in terms of economic development and the implications that face Institutional management in retaining students in the Higher Education system. Central to this study is the notion that student development theory can be used as a basis towards understanding the customers of Higher Education, how to better serve the customers needs and finally, retain students in the system through more effective management practices. The education sector is growing at an increasingly rapid rate as a result of strategic goals of countries and organisations such as the United Nations promoting the notion of education for all people (Altbach, Reisberg & Rumbley, 2009). The aim of the strategic goals adopted by developing countries in particular is to enhance the human capital or skills and knowledge of its people since education is a known contributor towards economic, social and political development. Higher Education in particular is known to contribute towards the human capital and economic development of a country. The Higher Education sector in South Africa for instance contributes approximately 1.5 percent to the country‟s gross domestic product (GDP), significantly higher than other industry sectors (apart from gold and agriculture) in the country (van Heerden, Bohlmann, Giesecke, Makochekanwa, & Roos, 2007). Figure 1.1 provides a context of the relevant importance of the higher education sector towards economic growth.

- Description: Cities must go further and further away to find new, more costly sources of water for human consumption while industries and agriculture continue to compete for increasingly scarce water resources. This may already be seen occurring within the Nelson Mandela Bay Metro where the severe drought being experienced during the past 18 months has severely depleted water supply dams. One of the main supply dams to the Nelson Mandela Bay Municipality is situated within the Baviaanskloof Nature Reserve and World Heritage Site. The potential of funding the Baviaanskloof Nature Reserve and World Heritage Site with payments for ecosystem services (water) obtained for water services supplied to the Nelson Mandela Bay Municipalities and agriculture in the Gamtoos River Valley will ensure financial sustainable for the Baviaanskloof Nature Reserve and World Heritage Site in the long term. This ability to become financially independent and generate its own income will place the Baviaanskloof Nature Reserve and World Heritage Site in a unique position within the conservation community in South Africa as only a very few protected areas are self sustaining through payment for an ecosystem service.

- Description: Literature and the cooperative movement in Malawi shows that the first cooperative was established in 1947. Since the economy of the country depends on agriculture, most cooperatives were strongly developed in the fields of agricultural production, and processing and marketing. The first coffee cooperative was registered in 1950, known as the Nchenachena Coffee Producers Cooperative Society. After Malawi 's independence in 1964, agricultural cooperatives were dissolved and government formed the Farmers Marketing Board (FMB) to take over all marketing activities of all crops, including coffee. The FMB was replaced by the Agricultural Development and Marketing Corporation (ADMARC) in 1967. After the dissolution of agricultural cooperatives, government saw the need for crop development and established Smallholder Coffee Authority in 1971. The Smallholder Coffee Authority worked up to 1999 when it collapsed because of administrative and financial problems. Due to the failure of the Smallholder Coffee Authority, the government of Malawi reintroduced agricultural cooperatives in 1999. Mzuzu Coffee Planters ' Cooperative Union was formed in 2006 following the re-introduction of cooperatives. The union is mandated to promote sustainable production, processing and marketing of Arabica coffee on behalf of the farmers. Since its inception, the output of coffee for export from the Mzuzu Coffee Planters Cooperative Union has increased from 156 tonnes in 2006 to over 400 tonnes in 2009. The increase in coffee exports was not by mere chance but a number of factors contributed to this success. The main reasons for this success were: • Strong prior relationship between the growers and the buyers • The uniqueness of the cooperative business model • The unique taste and quality of coffee grown • The introduction of a different approach to farming coffee Currently there is high demand for organic coffee and this could be a niche market that is not only rewarded with premium prices but also creates environmental friendly business. The union considers Fair Trade market as an alternative approach to conventional trade, aiming at improving the livelihoods of smallholder producers by improving payments, giving them fair prices and providing continuity in trading relationships.

This study also highlights the need for Eskom management to take into cognisance the unique rural prepaid customer service needs and how to meet them, perhaps a differentiated service approach rather than a one-strategy-fits-all approach. This is in view of gaps created between expectations and perceptions of service, especially in the reliability dimension that could require a concentrated or changed performance approach to close them.

- Description: Large scale viral outbreaks such as Conficker, the Code Red worm and the Witty worm illustrate the importance of monitoring malevolent activity on the Internet. Careful monitoring of anomalous traffic allows organiza-tions to react appropriately and in a timely fashion to minimize economic damage. Network telescopes, a type of Internet monitor, provide ana-lysts with a way of decoupling anomalous traffic from legitimate traffic. Data from network telescopes is used by analysts to identify potential incidents by comparing recent trends with historical data. Analysis of network telescope datasets is complicated by the large quantity of data present, the number of subdivisions within the data and the uncertainty associated with received traffic. While there is considerable research being performed in the field of network telescopes little of this work is concerned with the analysis of alternative methods of incident identifi-cation. This paper considers trading bands, a subfield of technical analysis, as an approach to identifying potential Internet incidents such as worms. Trading bands construct boundaries that are used for meas-uring when certain quantities are high or low relative to recent values. This paper considers Bollinger Bands and associated Bollinger Indica-tors, Price Channels and Keltner Channels. These techniques are evaluated as indicators of malevolent activity by considering how these techniques react to incidents indentified in the captured data from a network telescope.

- Description: The evaluation of the potential to use Ultra Performance Liquid Chromatography (UPLC) for the simultaneous quantification of all the actives in a multi-active tablet is described in this work. Part of the evaluation was to ensure that the necessary regulatory requirements were adhered to by ascertaining that an analytical method is suitable for a specific purpose through analytical method validation for the specific multi-active tablet. The UPLC method was also tested for the analysis of similar products, namely tablet formulations that contain similar active ingredients in the same proportions but with an additional active ingredient. A method for the simultaneous determination of paracetamol, caffeine and codeine phosphate was developed using UPLC technology. The UPLC developed method was more efficient than the existing in-house HPLC method. The UPLC method was then validated in accordance to ICH and USP guidelines. The application of this UPLC method for the analysis of similar products containing paracetamol, caffeine, codeine phosphate and one extra active ingredient was very challenging. The low concentration of the additional component, differences in sample matrix and differences in formulations added to the challenges. The direct application for the analysis of products Y and Z was not successful; however the method could be used as a platform for further research. A cost comparison between the UPLC and HPLC methods showed the UPLC method to be more cost effective. Thus, while maintenance costs are higher for the UPLC instrument, column costs are comparable to HPLC columns, but solvent and waste disposal charges decrease considerably due to lower solvent use. The reduction in instrument time dramatically improves the cost effectiveness of UPLC over HPLC due to a concurrent reduction in analyst time requirement. The results of this study show that the analytical costs associated with the analysis of multi-active drugs using HPLC procedures can be reduced substantially by the CONFIDENTIAL INTELLECTUAL PROPERTY OF ASPEN PHARMACARE implementation of UPLC technology. The hypothesis that the enhanced chromatographic power of UPLC can be leveraged to provide faster analysis times hence increased product throughput rates, and lower operating costs for the analysis of multi-active drugs was accepted. These advantages were achieved whilst meeting all regulatory requirements for analytical methods as required by regulatory bodies.

- Description: Family businesses constitute a large number of businesses worldwide contributing significantly to the global economy. Succession planning is a key issue influencing the sustainability of these family businesses. According to research, approximately 30% of businesses fail due to matters related to succession planning (Grote, 2003). Further research indicated that approximately 50% of family businesses do not have adequate succession plans in place. Hence, family businesses are exposed to significant risk in sustainability due to insufficient succession planning. An effective approach to succession planning in a family business increases the chance of success of a family business in both the short and long term. The purpose of this study was to develop a better understanding of approaches to succession planning in two family businesses in East London, South Africa. This purpose was to improve the commercial viability of family businesses and improve the body of knowledge from an academic perspective. To this end, a detailed literature study was conducted on family businesses and succession planning. A qualitative case study research paradigm was implemented to ascertain the nature of the approaches adopted by the two businesses. An interview process was conducted with the incumbent founders (fathers) and successors (sons) of the family business. This process suggested that each business requires a unique approach to succession plan which may include aspects of formal and informal processes. It is necessary to understand the nature of the family business, its interrelated relationships and context to adequately determine the success of a succession approach. It is for this reason that families aspiring long term sustainability should invest in effective succession planning approaches that integrate the nuances of the individual family business.

- Description: The escalation of poverty simultaneously with the decline of small-scale agriculture in the rural areas of the Eastern Cape in particular, raises serious concerns within the government circles in South Africa and among researchers. Of the nine provinces of South Africa, the rate of poverty in the Eastern Cape is a pathetic one and is the largest contributor to poverty statistics in the whole of South Africa. Machete (2004) stresses that high levels of poverty are visible in the rural areas and the large proportions of the people who are poor in South Africa are found in the rural areas. It is widely accepted that small-scale agriculture plays a vital role in and contributes substantially to socio-economic life of people living in the rural areas and is one of the strategies most suited to combat poverty for the majority of the people in the rural areas. This study explored the challenges that limit the effective use of land for subsistence agriculture as a strategy for poverty alleviation at Mpongo and Twecwana villages in Tsholomnqa. The study adopted a qualitative approach in order to get in-depth understanding of the challenges as experienced by the participants. The sample comprised of fifteen (15) subsistence farmers and three (3) extension officers from the department of agriculture. The data was collected from the participants through the focus group technique with an interview schedule containing open ended questions. The findings of the study indicated that the communities lack capital such as money, machinery, labour and other resources needed to pursue agricultural livelihoods. The findings also showed that agricultural infrastructure such as dams, rivers, fencing have deteriorated. Machete (2004, p.8) concurring with Pote (2008) says “inadequate physical infrastructure in the rural areas, particular in the former homeland areas remains a major obstacle to smallholder agricultural growth in South Africa”. In the two villages the situation is worsened by a total lack of irrigation scheme development. These communities rely entirely on seasonal and natural rainfall for their crops to be cultivated and grown. It was also found that the introduction of state grants contributed for the rural communities to do way with their traditional socio-economic agricultural livelihoods. The end results were for food production from gardens and communal fields come to a total collapse in many communities in the rural areas. The findings also show that youth is less interested to participate and pursue agricultural based activities in the rural areas. Williams et al (2008) claim that young people are unwilling to pursue agricultural studies as career of choice because of negative image attached to it. Many youths regard agriculture as an activity which belongs to adult and ordinary people. Drought was also cited as the worst natural disaster that has threatened the already disadvantaged small scale agriculture in these rural areas. These deficiencies have rendered subsistence agricultural centred activities to a total collapse.

- Description: The following treatise focuses on the ongoing conflict within the church regarding the issue of homosexuality. It is an important issue that has divided both churches and denominations and it continues to cause hurt in both the lives of Christians and non-Christians alike, both straight and gay. The popular position seems to be that the church, and Christians in general, are homophobic and believe that Christianity and homosexuality are not compatible. This research is a case study and focuses on a church in London. The research was carried out to discover whether this position, often portrayed by the media, was true of this church. It also sought to discover whether theories of conflict management and in particular John Burton’s theory of basic human needs could offer insight and alternative approaches in future discussions. The findings of this research offer hope in the situation in that they show this particular church is not homophobic, nor do the majority believe homosexuality and Christianity to be incompatible.

- Description: The study explored organizational communication at Algoa Bus Company (ABC) in Port Elizabeth. The exploration exercise was based on flows of communication at ABC. This research project captured the four flows of communication as they colour relations within the company. The four flows of communication are, namely: upward communication which refers to messages that flow from subordinates to superiors, downward communication flow which refers to communication directed to the lower levels of hierarchy by higher levels, horizontal communication flow which refers to communication amongst people who are at the same level of authority and diagonal communication flow refers to communication across the organisational levels. The study also explored the structure of such communication processes and from a normative point of view, it does expose weaknesses though.

An exploration of the causes of social unrest in Omay communal lands of Nyami Nyami district in Zimbabwe: a human needs perspective

- Description: One of the responsibilities of every government is to make provisions of basic needs for its citizens. The situation in Omay resembles people living during the dark ages when there was no constitutional government. The government should in accordance with the priorities of its people be seen to be improving the lives of its citizens by providing health, education, roads, communication facilities, and participation in decision making especially on issues that have a bearing on their lives. The human needs theory postulates that one of the most ideal ways of resolving protracted conflicts is by helping people meet their needs. Human needs are not for trading according to conflict scholar John Burton, implying that if one does not meet his or her needs he/she might do anything to strive to meet them. The people of Omay have been deprived of their needs in all facets; first the previous government relocated them to create Lake Kariba for the hydroelectric plant. They were not compensated. They were dumped on very arid, tsetse fly infested mountainous areas adjacent to game reserves and national parks where they have to make do with wildlife; some that destroy their few crops (elephants) and others that kill them or their animals (lions). As a minority group they have been engaged in social unrest and small skirmishes with government and other, bigger ethnic groups as a form of resistance. A deliberate affirmative action to channel funds towards raising their living standards and develop their area so that they meet their needs could be the panacea to the social unrest.

- Description: The battle for traditional leadership successions continue to have negative effects on many Tribal Authority Councils across Africa, for example, the Valoyi Tribe, part of Tsonga/Shangaan nation in South Africa, and the Godban chieftaincy conflict in the northern town of Yendi in Ghana. Community conflicts related to chieftaincy positions across South Africa are apparent. This study was an attempt to explore and describe the dynamics of the AmaTshezi chieftaincy conflict in Mthonjana village, Mqanduli. The analysis focused on exploring the AmaTshezi chieftaincy conflict in terms of conflict and conflict process theory. This explorative study sought to explore and describe the perceptions of eight ad hoc committee members (government officials) who had been involved with attempting to resolve the AmaTshezi chieftaincy conflict. The researcher conducted extensive face-to-face interviews with these committee members and thoroughly studied the necessary documents that informed the study. Thematic data analysis revealed latent conflict, conflict emergence, conflict escalation, conflict stalemate, and conflict de-escalation, as key conflict phases in the AmaTshezi chieftaincy conflict. A number of recommendations are made about how those in authority could better manage communal conflict. The recommendations may, for instance, be used in the formulation of policies to influence better conflict management by government and help the Eastern Cape House of Traditional Leaders to manage communal conflicts better and to facilitate public education programmes about issues relating to birthright leadership positions and lineage procedures.

- Description: The informal economy in South Africa and other parts of the continent is a safe haven for many who are unable to find jobs in the formal sector of the economy. In the case of South Africa, it is not only the nationals of the country who are striving to survive and generate their income from this sector. Since 1994, the country has experienced a huge influx of immigrants from other parts of the continent some escaping from dire living conditions in their home countries and looking for better life opportunities while many others were forced to migrate from their own countries as a result of political unrest and lack of stability and security. Among these later example is the Somali community who are the subject matter of this study. Many of these mainly African immigrants including Somalis got involved themselves in the informal sector of the South Africa. This has increased the competition in this sector and caused clashes between South Africans and immigrants who were also involved in the sector. This study examines the involvement of the Somali immigrants in South Africa’s informal sector. The study is exploratory in nature and tried to find the surrounding factors that impacted on the involvement of Somalis in the informal economy of Motherwell. The study has found that Somalis who arrived in Motherwell are generally young unmarried men who were attracted to the area mainly because there were affordable business opportunities in the township. Somalis financed their businesses through various resources including their savings from working while working inside and outside South Africa and from the contributions by their families and friends. Despite facing high levels of crime where many Somalis were killed and their property looted, they are still determined to stay in the township. This can be shown by their high level of savings and their intention to invest in the township. Although this research does not aim to be comparative in nature, personal and business characteristics of Somalis as well as South Africans who are also involved in the sector vii were compared. Because of this comparison, it has became clear that though price is an important factor in the business competition between the two groups, it is not the only factor, neither the most important, that creates friction and the shift of loyalty of customers from one side to another. Quality of service, the number of the people working in the business, responsibility towards the area the business serves, the strictness or the leniency towards customers who want to buy but are short of money and many other factors created a friendly atmosphere between the businesses run by the Somalis and their customers. The study showed that some of the Somali as well South African business owners were of this view. Although the vast majority of the Somalis have a minimum level of education, they still contribute positively to the economy of the township and the greater Nelson Mandela Bay. This is done through renting business premises, paying both direct and indirect taxes and taking the business services to remote areas of Motherwell. The study suggests that there is a need to sooth the relationship between the two groups particularly between Somalis and South Africans who are involved in grocery businesses through meetings, seminars, and other get-together activities. This can be done by South African Police Service, Somali Association of South Africa in Korsten, community elders from both sides and other concerned government institutions as well as the academic institutions particularly Nelson Mandela Metropolitan University. The business skills of both groups need to be uplifted in order to maximise their profitability and contribution to the people in the area.
