- Description: South Africa enjoys strong policy support for the integration of environmental issues into school curricula. However, much doubt exists over the extent to which this has been converted into appropriate classroom practice at the majority of under-resourced rural schools in the country. This article reports on a study which piloted a research tool which can be used to analyse teachers’ lessons, with the aim of gaining insight into the extent to which they integrate natural resource management issues. The research tool was based on Bernstein’s concept of classification and consisted of five indicators of natural resource management integration into Life Sciences lessons. The study contributes to the design of research tools that can be used to analyse and monitor the integration of environmental issues into teachers’ lessons. It also provides some insight into the environmental content of a sample of Grade 10 Life Sciences lessons at four rural underresourced schools in the Eastern Cape.

- Description: Recruitment, selection and transfer of educators were decentralized after South Africa became a democratic state in 1994 and shifted to School Governing Bodies. The legislation promoted a shared governance and participation of parents in issues that are related to recruitment, selection and transfer of educators, but parents are struggling and facing challenges in performing these tasks as School Governing Body members especially in the Butterworth district, as a result of that Butterworth district is experiencing problems with increasing number of disputes resulting from the appointment of educators after they have been recommended by the School Governing Bodies. This study focuses on the recruitment, selection and transfer of educators in the Butterworth district of the Eastern Cape Province of South Africa. The study sought to reveal the thinking behind government insistence on giving the School Governing Bodies a responsibility to recruit, select and transfer educators knowing fully well that they do not perform this responsibility. A qualitative approach was used to explore and challenge this phenomenon. This approach is concerned with understanding social phenomenon from the participant’s perspective. In depth semi – structured interviews with open ended questions were used to bring the researcher more closer to a more plausible perspective of this phenomenon. Moreover, they were used because they are the most appropriate method to capture the data. The findings revealed that School Governing Bodies are faced with challenges such as: high level of illiteracy, manipulation of School Governing Bodies by school management, unions and candidates, the issue of regionalism and kickbacks, capacity building and empowerment and role played by the Departmental Officials. By conducting this study, we hope that the findings might contribute in identifying the disjuncture between the policy and the practice in issues pertaining to educator recruitment, selection and transfers. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

- Description: Writing can at times be difficult. It is not without considerable anxiety that I undertake to write this particular review. Perhaps I should offer a short qualifier: this is not strictly a review but rather a collection of ideas around the works and their arrangement, as well as my own musings and reflections on Crump. I want to pick up on what I identify to be an approach that personalises Crump as a professor, colleague and artist (we find this tone embedded throughout the accompanying exhibition catalogue). 1 I have chosen to structure this essay using a series of trigger headings, some provocative and possibly even inflammatory, others more neutral and concerned with getting to the core of what this retrospective and posthumous show is all about. All the while my thinking is to channel a sense (or lack thereof, as it may turn out) of my own experience of his work and person.

- Description: In this paper we report on the synthesis and characterization of 1,4-benzene diamine (BDA) functionalized single walled carbon nanotubes linked to cobalt (II) tetracarboxy-phthalocyanine. The characterization of the conjugate was through UV–vis, FTIR and X-ray diffraction (XRD) spectroscopies and by transmission electron microscope (TEM) and electrochemical methods. The conjugate is used for the electrochemical characterization of diuron. The catalytic rate constant for diuron was 4.4 × 103 M−1 s−1 and the apparent electron transfer rate constant was 18.5 × 10−6 cm s−1. The linear dynamic range was 1.0 × 10−5–2.0 × 10−4 M, with a sensitivity of ∼0.42 A mol−1L cm−2 and a limit of detection of 0.18 μM using the 3δ notation.

AmaJobe is one of the most ancient traditional communities in the Eastern Cape, being able to trace their history back fourteen generations. Chief Sinuka, eight generations before Zanemali, the present chief was present at the battle between Tshawe and Cirha at the Mzimvubu river, during which battle amaJobe participated on behalf of Tshawe. This battle occurred some time before the year 1600, by which time amaJobe were already a distinct traditional community. The amaJobe are closely related to the amaNgwevu clan, in fact Sinuka was the senior brother of Tshangisa and the uncle to Rhudulu. , Bani, Zanemali, Chief (donor)

- Description: This paper reports on the synthesis and characterization of new manganese phthalocyanine (MnPc) complexes: 2,3-octakis-[(2-mercaptopyridine) phthalocyaninato] acetato manganese (III) (1) and its quaternized (hence water soluble) derivative: 2,3-octakis-{[(N-methyl-2-mercaptopyridine) phthalocyaninato] acetato manganese (III)} sulphate (2). The complexes were used to form self assembled monolayers (SAMs). Voltammetry proved that both of the SAMs are well packed, strongly passivating and act as selective and efficient barriers to ion permeability. Furthermore, surface coverage studies confirmed that the MPc macrocycles adsorb onto the gold electrode as monolayers. Both MPc SAMs were successfully used as electrochemical sensors of nitrite.

- 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: The synthesis and characterization of the new zinc phthalocyanine derivatives, tetra- (non-peripheral, 5) and octa-(peripheral, 6) substituted with 2-mercaptopyridine and their respective quaternized derivatives (8 and 9) are reported. Photochemical and photophysical properties of the new complexes are compared with those of the previously reported peripherally tetra-substituted complexes 7 and 10. The quaternized compounds exhibit excellent solubility in water, making them potential photosensitizers for use in photodynamic therapy (PDT) of cancer. Spectroscopic, aggregation, photophysical and photochemical properties of these complexes are also investigated and compared. Photophysical (fluorescence quantum yields and lifetimes) and photochemical (singlet oxygen and photodegradation quantum yield) properties of these phthalocyanine photosensitizers are very important for the assessment of these complexes as PDT agents. In this study, the effects of the position of the substituents and quaternization of the substituents on the photophysical and photochemical parameters of the zinc phthalocyanines are also reported. This study also showed that the water-soluble quaternized zinc phthalocyanines strongly bind to blood plasma proteins such as bovine serum albumin (BSA).

- Description: Homogeneous and heterogeneous photosensitized transformations of 4-chlorophenol (4-CP) and pentachlorophenol (PCP) using palladium octadodecylthiophthalocyanine (PdODPc) were investigated. Under heterogeneous conditions, the photosensitizer was supported on functionalized single walled carbon nanotubes (SWCNTs). Homogeneous photosensitization proved to be more effective than the heterogeneous reaction in terms of percentage of transformation achieved. The kinetics of heterogeneous catalysis proved that ads-PdODPc–SWCNT–COOH (where SWCNT has been functionalized with COOH groups) was reusable for 4-CP while its activity degenerated when reused for PCP. Singlet oxygen was confirmed as playing an active role in the reactions.

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: The increased interest in capital flows has made it imperative to understand how they impact a particular economy. The Global drive for an interlinked world economy has increased the need for monetary authorities and Governments to able to effectively deal with any negative spins off from capital flows and also be able to take advantage of positive effects capital flows may have on an economy. The study seeks to understand how the change to lift restrictions on capital flows into the South African economy may have impacted on economic growth. The study analyses the relationship that existed between capital flows, that is to say foreign direct investment (FDI) and portfolio investment (P_I) and economic growth under the period of capital controls (1975 Q1 to 1994Q1). Then study will then analyse the same relationship but this time under the liberalised period (1994 Q2 to 2010 Q2) and compare how the long run relationship has changed after capital account liberalisation. The study uses an endogenous model to determine the relationship. The study unlike most will focus on a single economy, which is South Africa and not use panel data like most previous studies. The study found that in the short run capital account liberalising aided economic growth as both FDI and P_I became significant, with positive coefficients and also found that there is long run relationship between economic growth and capital flows. In the long run FDI is significant while P_I is not. After liberalisation FDI adjusted faster in the long run than before liberalisation on its impact on economic output. Also of note was that the study found that under capital controls the conditional variance was constant but after liberalisation the relationship between capital flows and economic growth became more sensitive to negative news and the conditional variance was not constant thus indication of increased volatility. To maximise from opening up of capital accounts the economy should maintain sound macroeconomic policies. This will help shield the economy from the external shocks and this maintain economic growth. , Thesis (MA) -- Faculty of Management and Commerce, 2011

- Description: The increased interest in capital flows has made it imperative to understand how they impact a particular economy. The Global drive for an interlinked world economy has increased the need for monetary authorities and Governments to able to effectively deal with any negative spins off from capital flows and also be able to take advantage of positive effects capital flows may have on an economy. The study seeks to understand how the change to lift restrictions on capital flows into the South African economy may have impacted on economic growth. The study analyses the relationship that existed between capital flows, that is to say foreign direct investment (FDI) and portfolio investment (P_I) and economic growth under the period of capital controls (1975 Q1 to 1994Q1). Then study will then analyse the same relationship but this time under the liberalised period (1994 Q2 to 2010 Q2) and compare how the long run relationship has changed after capital account liberalisation. The study uses an endogenous model to determine the relationship. The study unlike most will focus on a single economy, which is South Africa and not use panel data like most previous studies. The study found that in the short run capital account liberalising aided economic growth as both FDI and P_I became significant, with positive coefficients and also found that there is long run relationship between economic growth and capital flows.

- Description: Although the interaction between the western colonizers and the African indigenous populations in the early eighteenth and nineteenth centuries produced responses that were mostly inimical to the development of African customary law, the thrust of the onslaught against its principles was somewhat diminished by political considerations. Undoubtedly, the significance that African customary law acquired during this period was a measure of the purpose that the colonial project found in it.

- Description: An optimal extraction method for the removal of templates from molecularly imprinted polymers (MIPs) is presented. The extraction method is based on pressurized hot water extraction (PHWE). PHWE was evaluated by application to three distinctly colored MIPs for chlorophyll (green), quercetin (yellow) and phthalocynine (dark blue) with subsequent monitoring of template removal and template bleeding by an ultraviolet spectrophotometer. The templates were washed-off and the extraction efficiency (EE) was compared to that of soxhlet and ultrasonic extraction methods. PHWE employed hot water at an optimal temperature of 220 °C, pressure of 50 bars and flow rate of 2 mL min−1 to thoroughly wash-off the respective templates from their MIPs. The EE evaluated for PHWE was over 99.6% for all the MIPs with no subsequent or minimal template bleeding (more than 0.01%). The washing procedure was simple and relatively fast as it was achieved in 70 min at the most. At 95% confidence level (n = 3), soxhlet and ultrasonic recorded EE that was not significantly different (more than 94.5% in all cases) from that of PHWE (less than 99.6% in all cases). Soxhlet and ultrasonic had washing procedures that were slower (over 18 h) and employed large quantities (400 mL) of organic solvents modified with acids. The percentage relative standard deviations (%RSD) for the EE and recovery results were less than 2.3% in all cases indicating the high reproducibility of the method. Overall, the three methods performed comparably in extracting templates. PHWE seems to be the method of choice as it employed water which poses no environmental threat.

- Description: Organizational citizenship behaviour is one of the important factors that enhance organizational effectiveness. The main purpose of this study was to explore the impact of Organizational commitment on Organizational Citizenship Behaviour (OCB). In this study, age and gender effects on OCB of tertiary institution employees were also examined. The data was collected from 68 academic and administration staff from the University of Fort Hare, Alice campus through questionnaires. The results show that 68 respondents are of the view that organizational commitment impacts positively in enhancing the organizational citizenship behaviour of the employees. The findings also reveal that age and gender play no role in the practice of employees OCB. Management can increase the levels of OCB in their employees by recognizing employees who engage themselves in such behaviour. Implications that can help management in the University of Fort Hare, Alice campus in augmenting the OCB of employees is also discussed. , Thesis (MCom) -- Faculty of Management and Commerce, 2011

- Description: This article discusses the role of privatization of security in Africa, but its focus is on private military and security companies (PMSCs). The article proceeds on the basis that there is need for effective regulatory frameworks for PMSCs that operate in conflict zones of Africa. Thus, it begins by appraising the existing normative standards at the international, regional and domestic level that apply to these companies, and thereafter, identifies their shortcomings in light of the prevailing security conditions within the continent. The article then posits broad theoretical imperatives for designing a more effective regulatory framework for PMSCs and concludes by proposing the establishment an overarching continental regime constructed on the basis of the suggested imperatives.
