- Description: This study was conducted against the backdrop of growing scholarly interest in the epistemic divide between formal, institutionalised knowledge, which guide government interventions in rural community development, and local knowledge, upon which rural communities construct their social existence. The study sought to understand why, despite their resilience and cultural embeddedness in South Africa's rural communities, indigenous self-help groups (SHGs) - as a particular form of indigenous rationality - remained on the periphery of contemporary community development interventions. The study was conducted in the communities of Dabhana, Feni and Mgwanlana in Peddie (Ngqushwa Local Municipality), Eastern Cape. Three SHG variants were eselected: a funeral group (Masingcwabane), an HIV and AIDS support groups, and a financial mutual (mgalelo) – all in the context of government-assisted community development. Empirical data was collected using a mini-survey, focus group discussion, in-depth interviews and key informant interviews. The findings revealed that SHGs were a collective model of indigenous knowledge and social interaction, driven by the belief that through 'sharing', 'reciprocity' and 'collectivism', what would ordinarily be a heavy burden for individuals became 'lighter'. Furthermore, while the institutional framework for community development mandated collaboration between government and SHGs, this framework created a stiff, bureaucratic canvass that alienated SHGs and stifled their operations. The study also found that partnership between the government and SHGs was characterised by fear and distrust on the part of government, and reluctance on the part of SHGs. Government's distrust was premised on the "informality" and "traditionality" of SHGs, and the fear that any investment in SHGs would go to waste. On the other hand, SHGs' reluctance to make themselves amenable to partnership with government seemed like a reaction to a "faulty, culturally insensitive" institutional framework which "delegitimised" grassroots development impulses. The study concluded that there existed in the rural community development arena an epistemic, ideational and practical chasm between government-driven development praxis and age-old indigenous initiatives, and that while the weaknesses of each knowledge domain were accentuated through this divide, development would continue to elude the grassroots communities unless the two knowledge domains interacted with, and leveraged, each other. , Thesis (PhD) (Sociology) -- University of Fort Hare, 2018

- Description: This article explores intersections between understandings of masculinity and nationalism. Etymologically, ‘patriotism’ refers to a love for a fatherland and a patriarchal order; it includes notions of loyalty, honour and a range of qualities often associated with conceptions of masculinity. But if gender remains fixed to these normative constructions, what happens to one’s sense of masculine identity when the national state changes? My interest lies in exploring how white South African men have been repositioned in terms of a shift in their gendered identification, with a reflection on the possibly tragic consequences of maintaining an overly rigid gender role identification. As long as masculinity is embedded within nationalism, it will be caught up within a defensive reactive mode which can turn self-destructive. In order to explore these ideas the article employs as its central metaphor the character of Dawid Olivier, who is the protagonist of Athol Fugard’s Sorrows and Rejoicings (2002).

- Description: In Zoë Wicomb's Playing in the Light, the main character's troubled sense of identity (brought about by her parents' shameful decision to ‘play white’) is viscerally symbolised by her discomfort in her own and others' homes. In her Cape Town apartment she has nightmares about other houses. Her visits to her family home, where her elderly father lives alone, are similarly burdened by presences and memories she finds unwelcoming. And, her extended vacation to the UK, once she has discovered her family's secret, is a choice of “a place in which to cry” (Wicomb 2006: 191).

- Description: To examine the different uses and perceptions of introduced Australian acacias (wattles; Acacia subgenus Phyllodineae) by rural households and communities. Eighteen landscape-scale case studies around the world, in Vietnam, India, Réunion, Madagascar, South Africa, Congo, Niger, Ethiopia, Israel, France, Portugal, Brazil, Chile, Dominican Republic and Hawai‘i. Qualitative comparison of case studies, based on questionnaire sent to network of acacia researchers. Information based on individual knowledge of local experts, published and unpublished sources. We propose a conceptual model to explain current uses and perceptions of introduced acacias. It highlights historically and geographically contingent processes, including economic development, environmental discourses, political context, and local or regional needs. Four main groupings of case studies were united by similar patterns: (1) poor communities benefiting from targeted agroforestry projects; (2) places where residents, generally poor, take advantage of a valuable resource already present in their landscape via plantation and/or invasion; (3) regions of small and mid-scale tree farmers participating in the forestry industry; and (4) a number of high-income communities dealing with the legacies of former or niche use of introduced acacia in a context of increased concern over biodiversity and ecosystem services. Economic conditions play a key role shaping acacia use. Poorer communities rely strongly on acacias (often in, or escaped from, formal plantations) for household needs and, sometimes, for income. Middle-income regions more typically host private farm investments in acacia woodlots for commercialization. Efforts at control of invasive acacias must take care to not adversely impact poor dependent communities.

- Description: This ambitious book begins with the statement ‘By and large, the states of sub-Saharan Africa are failures’ (p. 1) and then sets out to explain state failure in Africa and to provide some ‘rational policy fantasies’ in response to this failure. The book builds on the work of scholars like Robert Jackson, William Reno and Jeffrey Herbst, with the particular focus of Englebert's book being on the domestic implications of the unconditional recognition of the sovereignty of African states. African states are internationally recognised despite lacking the features and not being able to perform the functions typically associated with statehood. Englebert's interest is to examine some of the domestic effects of this unconditional international recognition.

- Description: In South Africa, English plays a dominant role compared to African lan-guages in empowering domain. Better access to Education through the use of African languages is an object of heated debate. This paper shows that an intervention involving the use of an African language in the domain of ICT Education can change the attitudes of Black universi-ty students. The methodology used included a survey with preliminary and follow-up questionnaires and interviews and an intervention involv-ing the use of localised software and of an on-line glossary of computer terms translated, explained and exemplified in an African language (isiXhosa). This experience increased the support for the use of African languages as additional LoLT, even in the English-dominated field of study of Computer Science. This is an initial step towards promoting linguistic equality between English and African languages and social equality between their speakers.

- Description: This study documents validation of vertebral band-pair formation in spotted gully shark (Triakis megalopterus) with the use of f luorochrome injection and tagging of captive and wild sharks over a 21-year period. Growth and mortality rates of T. megalopterus were also estimated and a demographic analysis of the species was conducted. Of the 23 OTC (oxytetracycline) -marked vertebrae examined (12 from captive and 11 from wild sharks), seven vertebrae (three from captive and four from wild sharks) exhibited chelation of the OTC and f luoresced under ultraviolet light. It was concluded that a single opaque and translucent band pair was deposited annually up to at least 25 years of age, the maximum age recorded. Reader precision was assessed by using an index of average percent error calculated at 5%. No significant differences were found between male and female growth patterns (P>0.05), and von Bertalanffy growth model parameters for combined sexes were estimated to be L∞=1711.07 mm TL, k=0.11/yr and t0= –2.43 yr (n=86). Natural mortality was estimated at 0.17/yr. Age at maturity was estimated at 11 years for males and 15 years for females. Results of the demographic analysis showed that the population, in the absence of fishing mortality, was stable and not significantly different from zero and particularly sensitive to overfishing. At the current age at first capture and natural mortality rate, the fishing mortality rate required to result in negative population growth was low at F>0.004/ yr. Elasticity analysis revealed that juvenile survival was the principal factor in explaining variability in population growth rate.

- Description: An econometric study was undertaken to determine the extent to which selected macroeconomic variables influenced stock market prices on the All-Share, Financial, Mining and Retail Indices of the Johannesburg Stock Exchange in South Africa from 1996:7 to 2008:12. The Johansen cointegration method was used to determine whether cointegrating relationships existed between the macroeconomic variables and the stock market indices. A Vector Error Correction model was estimated and found significant results that money supply, inflation, long and short- run interest rates, and the exchange rate all had an influence on stock market prices. Further, the VECM results for each sector indicated that certain macroeconomic variables had differing influences on each sector of the stock market. Impulse Response tests indicated that the selected macroeconomic variables caused shock to the sectoral indices in the short-run but that the effect was lagged. The Variance Decomposition tests conducted supported earlier evidence that the macroeconomic variables had a strong level of sectoral index determinacy in the long run. The results found that the All-Share and Financial Indices were negatively influenced by inflation and short term interest rates in the long run, while the Financial Index also had a negative relationship with long-run interest rates. Money supply was found to have a positive effect on all the indices. A weakening of the exchange rate was found to have a positive influence on both the Retail and Mining Indices, while it negatively affected the All-Share and Financial Indices. The long-run interest rate had a positive influence on both the Retail and Mining Indices. Overall the study finds that macroeconomic variables are important determinants of stock market prices in South Africa and that it is important to examine each sector of the stock market separately to capture what are different effects. The limitations of the study are that a different measure for exchange rates from the nominal rand/dollar exchange rate used here may yield more decisive results and provide insight into the link between exchange rate behaviour and performance of especially the retail sector.

An evaluation of lightweight classification methods for identifying malicious URLs

- 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: 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 number of multinational enterprises has increased substantially. In part due to the integration of national economies (the European Union), improvements in communication and technology and the opportunity to reduce costs as a result of globalisation. Transfer pricing and especially business restructuring within multinationals is a fairly new concept.Professional legal and audit firms have different views on how to approach business restructurings. This research analyses important transfer pricing aspects and the anomalies that arise through business restructurings. The research method used in this research paper is primarily qualitative, comprising the analysis of various documentary sources of data. Relevant South African and international case law, tax legislation, the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations, the Transfer Pricing Aspects of Business Restructurings Discussion Draft and other reports were consulted and analysed. Further the views of recognised legal and tax experts that have been published in technical journals and text books were also considered and examined. A hypothetical example of a business restructuring transaction was constructed in order to illustrate practical issues and different approaches to solving them. The research has argued that the arm’s length principle, which forms the bases of transfer pricing regulation, is not an exact science but theoretically it is the most suitable measure.It may not be able to incorporate all variables, such as the cost savings through synergies of multinational enterprises, but it promotes international trade and investment by ensuring that transactions are based on fair prices. Business restructurings create anomalies in applying the arm’s length principle but these anomalies can be dealt with within the regulatory structure. The business restructuring approach recommended is realistic and pragmatic, but more clarity may be needed in certain circumstances. The research has also discussed the avoidance of transfer pricing audits, including having appropriate transfer pricing policies and documentation.

- Description: A stable money demand function plays a vital role in the analysis of macroeconomics, especially in the planning and implementation of monetary policy. With the use of Johansen cointegration and error correction model estimates, this study examines the existence of a stable long-run relationship between real money demand (RM2 and RM3) and its explanatory variables, in South Africa, for the period 1990-2009. The explanatory variables used in this study are selected on the basis of different monetary theories and empirical works, including the Keynesian, Classical and Friedman’s modern quantity theory of money. Based on these theories, the explanatory variables used in this thesis are real income, an interest rate, the inflation rate ,the exchange rate and foreign interest rate. The signs of the coefficients of the variables are as expected from economic theory. The coefficients of real income, the exchange rate and foreign interest rate are positive, while the coefficients of the interest rate and inflation rate are negative. This study augments the cointegration and vector autoregression (VAR) analysis with impulse response and variance decomposition analyses to provide robust long run effects and short run dynamic effects on the real money demand. In addition a foreign interest rate to capture the impact of capital mobility on money demand in South Africa was used. Results from the Johansen test suggest that real money demand (RM2 and RM3) and its all explanatory variables are cointegrated. Hence, there is a long-run equilibrium relationship between the real quantity of money demanded and five broadly defined macroeconomic components namely, real income, an interest rate, the inflation rate, foreign interest rate and the exchange rate in South Africa. Overall, the study finds that the coefficients of the equilibrium error terms are negative, as expected, and significantly different from zero, implying that 0.16 and 0.1 of the discrepancy between money demand and its explanatory variables is eliminated in the following quarter. Application of CUSUM and CUSUMSQ stability test showed that real money demand (M2 and M3) is stable in South Africa. The impulse response analysis provided evidence that the real M3 money, national income, rate of inflation and the foreign interest rate have a significant impact on the real M3 money demand in the short run. However, remaining variables (the real exchange rate and prime overdraft rate), have only a transitory effect on the real M3 money demand. There was further evidence that real exchange rate, the rate of inflation and the foreign interest rate, have a significant impact on the real M2 money demand in the short run. However, remaining variables (the national income and prime overdraft rate), have only a transitory effect on the real M2 money demand. Results from the variance decompositions of the real money demand are basically similar to those from the impulse response analysis and reveal that the fundamentals explain some, but not all, of the variations of the real money demand. The results showed that the national income explains the largest component of the variation in the real M2 money demand followed by the exchange rate and foreign interest rate. Shocks to the other variables continued to explain an insignificant proportion of the variation in the real M2 money demand. The national income also explains the largest component of the variation in the real M3 money demand followed by the foreign interest rate and exchange rate. Shocks to the other variables continued to explain a less significant proportion of the variation in the real M3 money demand.The study finds that both real M2 and M3 are stable which makes monetary targeting a viable policy option for the SARB. , Thesis (MCom) -- Faculty of Management and Commerce, 2011

- Description: This is a comparative study of parental involvement in the governance of public and private schools in the Matatiele District of the Eastern Cape Province of South Africa. Parental involvement can range from occasional attendance of the school functions to partnership through parent teacher organizations and parent management bodies. Education is a national enterprise that requires the co-operation and participation of all the role players who are parents, community, teachers, learners and the Department of Education. The problem to be investigated in this study is: Why is it that parental involvement is more positive in the governance of private schools than that of public schools? Two schools were selected for the study and the researcher administered questionnaires personally by hand and conducted face to face interviews to collect the primary data. The responses of the administered questionnaire were tabulated and recorded in table form so as to give an accurate interpretation of what was revealed in the data. Patterns in the data were considered in order to provide an accurate interpretation of the information. The findings were divided into two, that is: findings from the public school and those from private schools. From the public school it was found that: parents are not involved in the governance of the school; the school does not involve parents on financial matters; parents do not attend meetings when invited; they do not know their roles and responsibilities, for example, according to the South African Schools Act (SASA), parents must be actively involved in the governance of the school in their community and that there is an element of ignorance and negligence on the part of parents towards their children’s education. From the private schools it was found that: parents are more involved in the governance of the school; they attend and participate actively in school meetings; the school involves parents in financial matters and as such the financial support from the parents is very good; parents are much involved in the monitoring of the progress of their learner’s education and are passionate about the school and seem to own the policies and the governance of the whole school system. The conclusion drawn from the study is that private schools allow for parental involvement in the governance of their schools whereas in public schools parental involvement is low. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

- Description: The post-apartheid era necessitates the rethinking of white identities in South Africa. One way in which some white South Africans are seeking to redefine themselves is through describing themselves as African. However, claims by white South Africans that they too are Africans have been met with mixed responses from black South Africans. In this article I use contributions to an online university students' forum to explore ways in which some white South Africans are embracing an African identity and to consider ways in which some black South Africans are responding to white South Africans' shifting identities. I use contributions to this forum as a starting point to think about the possibilities and limitations that the embracing of an African identity has for the development of what Frankenberg calls ‘anti-racist forms of whiteness’ among white South Africans.

- Description: At the end of Lecture 3 of The Empirical Stance, Bas van Fraassen suggests that we see the change of view involved in scientific revolutions as being, at least in part, emotional. In this paper, I explore one plausible way of cashing out this suggestion. Someone’s emotional approval of a description of the world, I argue, thereby shows that she takes herself to have reason to take that description seriously. This is true even if she is convinced—as a scientific community is when it considers alternative theories—that this description is false, that it is not the way the world is.

- Description: Only limited information is available in the literature on the role of soil mineral surfaces in the sorption of hydrophobic organic pollutants. This knowledge gap is addressed through the assessment of biphenyl sorption to kaolinite, illite and bentonite; using the batch equilibration technique with incubations lasting 6 or 21 days at 28 ± 2°C in the dark [RT1]. Sorption of biphenyl onto kaolinite followed the Freundlich sorption isotherm, whereas linear sorption isotherms were observed on illite and bentonite [RT2]. The biphenyl sorption partition coefficient on kaolinite ranged from 0.1 to 9.1 cm3.g-1 after 6 days and no sorption was observed after 21 days. This could have been caused by a completely reversible sorption or a loss of binding capacity after 21 days [RT3]. The respective values of the biphenyl sorption partition coefficient on illite and bentonite ranged from 20.3 ± 0.3 to 120 ± 8 cm3.g-1.Sorption equilibrium on the internal clay surfaces was reached after 6 days, as indicated by the sorption data for illite and bentonite [RT4]. Access of biphenyl molecules to the internal clay surfaces is a function of the ionic strength of soil solution and the soil organic matter is the dominant site for biphenyl sorption after 6 to 21 days.

- Description: Abstract text The study investigated the factors that lead to the high failure rate of grade 12 learners of the two high schools in the Ngqeleni area of Libode Mega District of the Eastern Cape, South Africa. The study was qualitative in nature; therefore interviews were used as the method of collecting data. Seven SMT members, four parents and four learners were, randomly selected from the two schools in the Ngqeleni area of Libode Mega District. The researcher randomly selected the participants then interviewed them. The researcher used a video recoder as an instrument to record the responses from the participants. To analyse data, the researcher transcribed the interview responses and interpreted them. The main findings of the study showed that the high failure rate was caused by the following factors: over-croweded classes, shortage of teaching and learnin~ materials, lack of parental involvement, teachers' low morale, poor learner discipline, teachers experiencing problems in implementing government policies, work-load and as such teaching becoming stressful. The researcher in his study therefore recommends that the Department of Education plans more workshops for schools to capacitate them. There should be provision for more classrooms and incentives for teachers.
