- Description: This research introduces an electromagnetic (EM) noise generator known as the FRIES noise generator to mitigate and obfuscate Side Channel Analysis (SCA) attacks against a Raspberry Pi. The FRIES noise generator utilizes the implementation of the Secure Hash Algorithm (SHA) from OpenSSL to generate white noise within the EM spectrum. This research further contributes to the body of knowledge by demonstrating that the SHA implementation of libcrypto++ and OpenSSL had different EM signatures. It was further revealed that as a more secure implementation of the SHA was executed additional data lines were used, resulting in increased EM emissions. It was demonstrated that the OpenSSL implementations of the SHA was more optimized as opposed to the libcrypto++ implementation by utilizing less resources and not leaving the device in a bottleneck. The FRIES daemon added noise to the EM leakage which prevents the visual location of the AES-128 cryptographic implementation. Finally, the cross-correlation test demonstrated that the EM features of the AES-128 algorithm was not detected within the FRIES noise.

- Description: The syntheses of zinc(II) tetra–[3–(4–phenoxy) (propanoic acid) phthalocyanine] (2) and zinc(II) mono–[3–(4–phenoxy) (propanoic acid) phthalocyanine (3) are reported in this work. Compounds 2 and 3 were covalently linked to glutathione capped silver (AgNPs–GSH), gold (AuNPs–GSH) and silver-gold alloy (Ag3Au1NPs–GSH) nanoparticles (NPs) via an amide bond formation to afford the conjugates: 2–AgNPs–GSH, 3–AgNPs–GSH, 2–AuNPs–GSH, 3–AuNPs–GSH, 2-Ag3Au1NPs–GSH and 3-Ag3Au1NPs–GSH. The photophysicochemical behaviours of the compounds and their conjugates with NPs were assessed in solution. The conjugates afforded a decrease in fluorescence quantum yields and lifetimes with improved triplet quantum yields in comparison to the compounds. Accordingly, the AgNPs and AuNPs conjugates with the compounds afforded high singlet quantum yields. On the contrary, the conjugates of the alloy afforded decreased singlet quantum yields probably due to the screening effect. The compounds and their conjugates with NPs could serve as a viable and efficacious photosensitizer for photodynamic therapy.

- Description: The purpose of the study was to investigate on the nature of records management in the office of the Premier Supply Chain Management. This study focuses on the Supply Chain Unit in the office of the Premier in the Eastern Cape Province of South Africa. The study sought to investigate the classification systems in place that is records management policy, procedure manual and file plans. The legal framework that regulates archives. Data was collected using open-ended questionnaire. The target population of this study included all the officials within the Office of the Premier. The sample of 15 was derived from the supply chain management officials, records management managers and directors. The study adopted a qualitative research methodology, which is multimethod in its orientation, which involves an interpretative, naturalistic emphasis to its subject issue. Findings from the study revealed that the unit had its internal records management policy, an official framework document that outlined the processes involved in organising records within the department. Thus, there are policy frameworks within the department even though not clearly described to other employees, which might lead to risks in the management of records. The study also revealed that most records personnel were not trained to effectively manage records. It was also indicated that there is a lack of proper filing system and or electronic records management system. Hence, for effective and efficient records management, the study recommends the creation of a web-based integrated system for communication and where records can be accessed within one system. The study also recommends proper training of records personnel to mitigate risks. Hence, the study recommends that senior management create and implement a records management program that clearly outlines the procedures of records management, risks factors and how to minimize them. This will aide in good practice, uniformity, standardization, high levels of professionalism, accountability, and transparency. , Thesis (MLIS) -- Faculty of Social Sciences and Humanities, 2017

- Description: The coronal mass ejections (CMEs) and solar flares associated with extreme solar activity may strike the Earth's magnetosphere and give rise to geomagnetic storms. During geomagnetic storms, the polar plasma dynamics may influence the middle and low-latitude ionosphere via travelling ionospheric disturbances (TIDs). These are wave-like electron density disturbances caused by atmospheric gravity waves propagating in the ionosphere. TIDs focus and defocus SuperDARN signals producing a characteristic pattern of ground backscattered power (Samson et al., 1989). Geomagnetic storms may cause a decrease of total electron content (TEC), i.e. a negative storm effect, or/and an increase of TEC, i.e. a positive storm effect. The aim of this project was to investigate the ionospheric response to strong storms (Dst < -100 nT) between 2011 and 2015, using TEC and scintillation measurements derived from GPS receivers as well as SuperDARN power, Doppler velocity and convection maps. In this study the ionosphere's response to geomagnetic storms is determined by the magnitude and time of occurrence of the geomagnetic storm. The ionospheric TEC results of this study show that most of the storm effects observed were a combination of both negative and positive per storm per station (77.8%), and only 8.9% and 13.3% of effects on TEC were negative and positive respectively. The highest number of storm effects occurred in autumn (36.4%), while 31.6%, 28.4% and 3.6% occurred in winter, spring and summer respectively. During the storms studied, 71.4% had phase scintillation in the range of 0.7 - 1 radians, and only 14.3% of the storms had amplitude scintillations near 0.4. The storms studied at SANAE station generated TIDs with periods of less than an hour and amplitudes in the range 0.2 - 5 TECU. These TIDs were found to originate from the high-velocity plasma flows, some of which are visible in SuperDARN convection maps. Early studies concluded that likely sources of these disturbances correspond to ionospheric current surges (Bristow et al., 1994) in the dayside auroral zone (Huang et al., 1998).

- Description: The marine red algae of the genus Laurencia have been widely studied for their structurally diverse and biologically active secondary metabolites. We report here the natural product investigation of the organic extract of a newly identified South African endemic species, Laurencia alfredensis. A sequence of column chromatography, preparative TLC and normal phase HPLC resulted in the isolation of eleven compounds comprising three labdane-type diterpenes (1-3), four polyether triterpenes (4-7), three cholestane-type ecdysteroids (8-10) and a glycolipid (11). Compounds 1-3, 5-8 and 10 have not previously been reported, while compound 9 is reported here for the first time from a natural source and the known compound 11 isolated for the first time from the genus Laurencia. The structural elucidation and the relative configuration assignments of the compounds were accomplished by extensive use of ID- and 2D-NMR, HR-ESI-MS, UV and IR spectroscopic techniques, while the absolute configuration of compound 1 was determined by single-crystal X-ray diffraction analysis. All compounds were evaluated against the MDA-MB-231 breast and HeLa cervical cancer cell lines. Compound 2 exhibited low micromolar antiproliferative activity (IC50 = 9.3 gM) against the triple negative breast carcinoma and compound 7 was similarly active (IC50 = 8.8 gM) against the cervical cancer cell line.

- Description: 'Microsporidia' is a term used for organisms belonging to the phylum Microspora, which contains approximately 187 genera and 1500 species (Corradi 2015). They are obligate intracellular parasites with no active metabolic stages of the life cycle occurring outside of the host cells (Franzen & Muller 1999; Garcia 2002; Tsai et al. 2003; Huang et al. 2004). They exhibit eukaryotic characteristics such as a membrane-bound nucleus, an intracytoplasmic membrane system, and chromosome separation occurs on mitotic spindles. However, they also exhibit prokaryotic characteristics such as possession of a 70S ribosome, lack of true mitochondria and peroxisomes, a simple version of the Golgi apparatus, and a small genome which is much less complex than those of most eukaryotes (Franzen & Muller 1999; Garcia 2002). Microspo- ridia are parasitic in all major groups of animals, both vertebrates and invertebrates (Sprague 1977; Franzen & Muller 1999). Microsporidia were first recognised as pathogens in silkworms by Nageli (1857), and now have been found to infect many hosts such as humans, insects, fish and mammals (Stentiford et al. 2016).

- Description: This chapter addresses the need for innovations in geography teacher education programmes in a developing world context. More specifically, it responds to the need for practical ‘how to’ examples for ESD integration into school geography by de-scribing a pedagogical experiment that was piloted with in-service Namibian teachers and education development offic-ers (EDOs) enrolled for a Bachelor of Education (Honours) de-gree in 2014. The theoretical constructs underpinning the ex-periment’s design and pedagogical approach as well as the teacher professional development model are described. This is followed by a description and justification of the methodology used to answer the research question: ‘How can issues-based enquiry enable the integration of ESD at the micro level of the classroom?’ The findings of the experiment provide evidence of how issues-based enquiry, underpinned by active learning and constructivist epistemology and a model of teacher pro-fessional development located in reflexive practice, enabled the teachers to acquire foundational knowledge and pedagog-ical content knowledge for effective integration of ESD into school geography. This chapter may offer other teacher educators some guidelines on how to develop teacher capacity to integrate ESD into their own programmes.

- Description: publisher version , In reflecting on the contributions to Volume 33, it is evident that a variety of theories about learning and social change inform the scholars in environmental education, ranging from behaviourist, to social behavioural, constructivist and social constructivist learning theories, social and critical realism, and more. What unites these papers is a shared concern about learning in relation to the future well-being of the planet and its people. New scholars entering the field of environmental and sustainability education have the task of mastering not only the social– ecological subject matter of the field, but also their chosen learning theories. In this regard, drawing on the back copies of the SAJEE can be of great value. Much research and writing has already been done on curriculum, education and learning inside and outside of formal institutions, yet many more questions remain. The field is best advanced by noting and building on, challenging and advancing past studies and existing scholarship. The fact that all 33 Volumes of the SAJEE are available online, just a ‘few clicks away’ from any student or supervisor with Internet access, is therefore an enormous boon. We encourage readers and future authors to draw on the work in this and other environmental education journals as they conceptualise, design and reflect on their own studies.

- Description: Attribute-based Access Control (ABAC) is an access control model where authorization for an action on a resource is determined by evalu-ating attributes of the subject, resource (object) and environment. The attributes are evaluated against boolean rules of varying complexity. ABAC rule languages are often based on serializable object modeling and schema languages as in the case of XACML which is based on XML Schema. XACML is a standard by OASIS, and is the current de facto standard for ABAC. While a JSON profile for XACML exists, it is simply a compatibility layer for using JSON in XACML which caters to the XML object model paradigm, as opposed to the JSON object model paradigm. This research proposes JSON Schema as a modeling lan-guage that caters to the JSON object model paradigm on which to base an ABAC rule language. It continues to demonstrate its viability for the task by comparison against the features provided to XACML by XML Schema.

- Description: WQSAM is a practical water quality model for use in guiding southern African water quality management. However, the estimation of non-point nutrient inputs within WQSAM is uncertain, as it is achieved through a combination of calibration and expert knowledge. Non-point source loads can be correlated to particular land cover types. Although observed water quality data through which non-point source loads can be estimated are scarce, land cover databases exist covering the entire area of South Africa. To reduce the uncertainty associated with estimat-ing non-point source loads, this study describes a formal model to link the nutrient signatures of incremental flow to land cover. Study catch-ments incorporating the fynbos, grassland, savanna and thicket biomes were identified. Instream nutrients of 25 sites were modelled using WQSAM and calibrated against observed data. Multiple regression was used to investigate the relationships between the calibrated nutrient signatures of incremental flow from WQSAM and land cover within study sites. The regression models reflected greater non-point loads from cultivation-and urban-related land cover categories. The nutrient signatures of incremental flow obtained through the multiple regres-sions were consistent with those obtained through calibration of the WQSAM model at higher signature values, whereas discrepancies were evident at lower values. It is argued that this formal modelling ap-proach for linking land cover to nutrient signatures of incremental flow can be implemented for situations where it is known that there are strong non-point inputs of nutrients into a river reach. The statistical model presented in the current study could potentially be applied as an alternative to the water quality model as a relatively simple method to estimate non-point source loads of nutrients from tributary catchments in South Africa.

- Description: This thesis is a case study of how church, land and dispossession of land has influenced identity formation of a coloured community in the Eastern Province, namely the Klipfontein community. Coloured history in the Eastern Province has largely been neglected. This study attempts to rectify such a lack of in-depth enquiry as it may lead to misinterpretations that may influence contemporary politics and identity formation. Through research based on primary sources, it is evident that the social landscape of Klipfontein Farm and the relationships between that community and surrounding black African and white communities have largely been shaped by the stipulations contained in the joint will of the community’s ancestors: Dirk and Sarah Janse van Rensburg. The land devolved into a trust and has been administered by trustees since the death of the first spouse in 1877. By keeping the land in a trust, it enabled the descendants to continue to live on the farm in perpetuity, without the risk of being forced off the land via financial restraints or racially-based legislation. But the usufructuaries could also never fully utilise Klipfontein as an agricultural concern due to a combination of a lack of equipment and skill, and the provisions of the will. These complications inevitably led to inter-familial disputes and tension. Before 1939 there had already been three court cases dealing with the interpretations of the Will. In that same year the Supreme Court ordered that tracts of the land, including a part of Boesmansriviermond village, be sold in order to pay off arrear rates and taxes. Although the responsibility for these sales lay with the trustees, the community has been suspicious of the usufructuaries ever since. A key element of the Klipfontein identity is their religion. The church legitimises their right to the farm - against those who wish to take that right away. Their claim to occupation is couched in scriptural discourse, viewing Klipfontein as 'their Garden of Eden' that God gave to the stamvader, Dirk Janse van Rensburg. This seemed to have been partially successful for the Klipfontein community in staving off harassment by authorities. It also caused friction between the community and the black African residents. Some usufructuaries and family members felt that such right was exclusively given to the coloured community and so they became increasingly annoyed by the black Africans who settled there. Other usufructuaries did not share this feeling. They allowed evicted black African farm labourers to settle on certain portions of Klipfontein until the late 1970s. The black African population rapidly increased due to misinformation and evictions from neighbouring farms. This only further exacerbated the inter-familial conflict between usufructuaries, flaring tensions between the black Africans and their reluctant hosts as well as animosity from the white community towards Klipfontein. In 1979, after a series of court cases, a decision was made to remove all the African settlers by force and relocate most of them to the ‘homeland’ of Ciskei. The rest, who were of ‘working-age’ were left behind in a ‘temporary emergency camp’ on the outskirts of Kenton-on-Sea. The effects of these removals still impact the relationships between the different racial groups in the area to this day.

- Description: The right to language and the right to healthcare services are human rights which are enshrined in the Constitution of the Republic of South Africa. Section 6 (5) of the Constitution and Section 1.3 (b) and (e) of the Eastern Cape Provincial Language Policy provide protection against unfair discrimination on the grounds of language; while sections 30 and 31 (1) of the Constitution refer to people’s rights in terms of cultural, religious and linguistic participation. Section 27 (a) states that ‘everyone has the right to access to healthcare services’. In accordance with the Constitution, in 2011 the National Department of Health passed a Policy on Language Services. This policy aims to facilitate equitable access to government services and information, as well as respect for language rights as spelled out in the Constitution. The Policy on Language Services further aims to promote multilingualism in the National Department of Health and to allow people to access information in a language of their choice, understand important messages and the language necessary for informed and participatory decision making (Department of Health 2011:1). Given the above policy and Constitutional provisions as far as policy commitment is concerned, the crucial issue remains the implementation of such policy to ensure that the right to access to health and language are realised. The study provides an analysis of the Policy on Language Services 2011 as it relates to language rights and the delivery of health services, focusing on the roll out and implementation process and the public awareness of the policy. This study primarily focuses on the role language plays in accessing public healthcare in primary healthcare facilities in the Grahamstown and Cofimvaba. The study looked at communication between patient and healthcare providers and whether healthcare services were provided in the language of the patient or the language the patient knows best. This study further assessed indications of patients’ comprehension of information such as medical instructions on packaged medicine, comprehension of posters, pamphlets and health education sessions in order to fully participate in the process of their health status. The data of this research was collected from healthcare providers and patients in primary healthcare facilities in Grahamstown and Cofimvaba in the Eastern Cape. The research methods used was in-depth interviews, non-participant observations as well as content analysis such as sign/direction posts, medical labels and information boards. These methods were used to determine whether language plays a role in accessing quality healthcare services in these facilities. The research found that the lack of implementation of language and health policy resulted in the perpetuation of language barriers in the healthcare sector. The study therefore argues that adequate healthcare can only be provided if and when healthcare providers and patients are able to communicate with each other in the language they know best or feel most comfortable in. Thus meaning the implementation of the current Constitutional and policy provisions is crucial to language and access to healthcare services.

- Description: Conjugates of zinc tetracarboxyphenoxy phthalocyanine (ZnTCPPc) and zinc tetraaminophenoxy phthalocyanine (ZnTAPPc) with amine and carboxyl functionalised cobalt ferrite magnetic nanoparticles (CoFe2O4 MNPs), respectively were electrospun into polystyrene (PS) fibers. The resulting composites; ZnTCPPc-CoFe2O4/PS and ZnTAPPc-CoFe2O4/PS were compared based on their photophysical properties and photocatalytic efficiencies in degrading Orange G (OG) using laser as the photoexcitation source. The photocatalytic efficiencies of ZnTCPPc-CoFe2O4/PS and ZnTAPPc-CoFe2O4/PS were compared based on them having different lengths in the linkage chains between the Pcs and CoFe2O4 MNPs and different sizes. Covalent linkage of the Pcs to the CoFe2O4 MNPs enhanced the singlet oxygen and reactive oxygen species (ROS) production of the Pcs and CoFe2O4, respectively hence ZnTCPPc-CoFe2O4/PS and ZnTAPPc-CoFe2O4/PS were found to be more effective photocatalysts than their respective Pcs and CoFe2O4 MNPs. Moreover, the kinetic analyses of the photodecomposition of OG showed that the degradation was in agreement with both pseudo-first order kinetics and followed the Langmuir–Hinshelwood model.

- Description: This article investigates the participation enablers and learning affordances identified by teachers through participation within an in-service community of practice (CoP) of primary teachers called the Numeracy Inquiry Community of Leader Educators (NICLE) in the Eastern Cape. The article draws on three qualitative sources of data: the annual teacher questionnaires of 42 participating teachers, interview data from 8 of the 42 sampled teachers and reflective journal entries of these 8 teachers over the first 2 years of NICLE. All three data sets point to teachers foregrounding the affordances and enablers of NICLE participation across the fundamental elements of a CoP, namely domain, community and practice. We illuminate the way in which teachers' identification of learning affordances relates to these three structural features of a CoP. In concluding, we argue that explicit consideration of these structural elements, and their interrelationship in the design of in-service programmes, could enable clearer articulation of programme aspects and support reflection on the coherence between teacher feedback on these as programmes evolve.

- Description: publisher version , Preface by Prof Narend Baijnath: “Teaching and learning are never neutral. Every aspect is ideological in nature: from the admission of students, to the selection of curriculum content, to the adoption of learning materials, to the pedagogical approach, to the mode of assessment and the quality of the feedback. The form of disciplinary knowledge may vary from the more subjective and contentious to the more objective and broadly accepted, but teaching and learning remain highly political acts across all institutions, faculties and disciplines. So it is unsurprising that when a country undergoes major social change, ideological demands are placed on teaching and learning.” (HE Reviewed, CHE 2016 p.143). There are many and diverse influences on teaching and learning as a political act, from broad social movements that challenge what is taught, to the ways in which resources have historically been allocated, to the values and goals of different disciplines, and the more immediate institutional and faculty contexts in which they take place. Learning to teach in higher education in South Africa is a timely and well-researched contribution to understanding the influences of that more immediate layer, that is, of institutional contexts, on the professional learning of academics in their roles as teachers. It explores questions of whether it matters to the professional learning process whether one is teaching in a context in which resources are scarce, or whether the departmental leadership style is authoritarian, or whether an institution has a strong drive to increase research output. And if it matters, what are the implications for facilitating opportunities for academics to ‘learn to teach’ in higher education? Undertaken by a team of academic staff developers across eight institutional contexts, this research report offers a comprehensive, nuanced and theorised set of insights into the role that context plays in the ways in which academics learn to teach. Such insights can inform the development of professional learning initiatives at both the institutional and national policy levels. The report is one of the outcomes of a large-scale study carried out between 2011 and 2016, made possible by funding from the National Research Foundation. It has spawned many research articles, books and PhD studies (see Appendix One) and has thus in itself provided a vehicle for the development of further research and researchers on the subject. The team chose to work collaboratively, with all the possibilities and difficulties that that entails, as reflected on in Chapter 7. Thereby, it also offers an illuminating reflection and insights into such research methodology. While the report does not specifically set out to offer anything new or surprising about the cultural and contextual differences between institutions, it does offer a coherent interpretation of such complex and intersecting conditions examined through a single theoretical lens. Indeed, the concepts of ‘structure, culture and agency’ as developed in the work of the social realist, Margaret Archer, formed the theoretical canvas for the study. The theory allows for the analytical separation of different domains for the purposes of understanding the interplay of relations, but it also offers a hope of bringing about social transformation through exercising particular modes of reflexivity. As the report argues, quoting Archer, transforming our positions in society is possible, but “their transformation depends partly on the subjective reflexivity of primary agents in seeking to play an active part in reshaping society’s resource distribution”. The researchers may not always have found it easy to apply a single theoretical lens, but the theory based study provides a coherent representation of the differences and similarities between the institutional contexts of the eight universities, throwing into relief their different influences on professional learning, and points to pathways towards the improvement of teaching and learning in South African higher education. A major contribution of this report that is likely to influence the discourse on teaching and learning significantly, is the conceptual shift from ‘professional development’ to ‘professional learning’. As an external reviewer noted, “in the context of the decolonization debate, [this shift] has the potential to offer a more flexible continuum in which to position different learning opportunities”. It also recognises the importance of group and individual agency and the importance of informal contexts in learning to teach. 12 | Monitor 14 | Learning to Teach in Higher Education in South Africa The publication of this research report takes forward the CHE’s ongoing endeavours to improve and enhance the quality of teaching and learning in higher education. It serves to complement the more practical implementation of quality assurance in higher education, which for the CHE has largely entailed a focus on teaching and learning, whether in accreditation, audits or the Quality Enhancement Project (QEP) that began in 2014 in which one of the four focus areas that universities were asked to engage with was “enhancing academics as teachers”. Participation in the QEP over the past three years has contributed to a heightened awareness across the sector of the importance of academics developing competence in university teaching, particularly given the increased emphasis being placed on student success by both the government and higher education institutions themselves. As a result, universities are becoming more intentional in their efforts to help academics develop this competence. The release of the study is therefore timely, as not only will it add to our collective understanding of the complexities and nuances in the interrelationships between structure, culture and agency that inform and influence academics in their roles as teachers, but it will serve as a useful resource for institutions in their efforts to enhance university teachers and teaching. The Higher Education Monitor series, as was elaborated in the first issue in 2003, “aims to stimulate research and the production of knowledge and interpretive frameworks that could contribute to better theorisation of higher education, more rigorous analysis of higher education complexities and more effective strategies for change and progress”. It is our hope that this report will do exactly that. , We thank the National Research Foundation for funding the project that made the study and the ensuing report possible, Professor Brenda Leibowitz for leading the team of researchers, our external reviewers, and the individual authors who took the time to present drafts of their chapters to Dr Webbstock of the CHE at a workshop in May 2016.

- Description: Taking a leaf from the book under review, I’ll start by injecting an autobiographical element. Much of what Sanders examines here echoes my own experience, after Zimbabwe’s independence, of heading to a remote mission school to teach for two years. Part of my purpose was to learn better Shona, the majority language from which I had been systematically discouraged by my colonial education. It was, in a way, a gesture of reparation, or addressing a nagging “white guilt”, or at least of assuaging a sense of fruitless loss and exclusion. I was nowhere near as successful in attaining fluency as Sanders seems have been in learning Zulu; and now that I live in the Eastern Cape, my efforts to learn Xhosa have been similarly patchy and faltering. One thing is evident throughout Sanders’s dense discussions: long-term, assiduous application and pe¬riods of total immersion are vital—and as he points out, few whites in South Africa have carved out the time and energy to do so, while willy-nilly expecting the black majority to learn their language. (An endnote does aver that, according to census figures, a surprising 16,000-plus whites, and a similar number of Indians, in KwaZulu-Natal, list Zulu as their first language.)

- Description: Political theorists like Bickford (1996) and media theorists like Couldry (2006) have introduced the concept of listening as a complement to long-standing discussions about voice in democracies and in the media which serve the democratic project. This enhanced understanding of voice goes beyond just hearing into giving serious attention to, in particular, marginalised voices. This article reports on an investigation into the ways in which mainstream and community media in the Eastern Cape, South Africa, understand listening as an important part of their role as journalists. Interviews probed the attitudes of journalists and editors towards listening, and also interrogated their own understandings of their role in South Africa, particularly in relation to young people who are finding their political “voice”.
