Description: The political posters produced by art centres are their most celebrated contribution to the struggle to end Apartheid. However art centres made another valuable contribution by encouraging a form of critical selfhood. This type of internal struggle against inferiority was formulated by the Black Consciousness Movement and is an important element in transformation. However with the end of Apartheid this contribution seems to have been dismissed, alongside poster production, as irrelevant to the new nation. The author investigates how the art centre functioned as a vehicle for critical selfhood and argues for its contemporary relevance.

Description: This article discusses the possibility of South Africa enacting a new law regulating private military/security companies (PMSCs) beyond the Prohibition of Mercenary Activities and Regulation of Certain Activities in Country of Armed Conflict Act of 2006. It argues that such a possibility arises from the policy direction expressed in the Defence Review of 2012, and the recent developments at the international level, which indicate a shift towards accommodation of PMSCs as legitimate players in the security sector. The article surveys the current state of national and international law relating to PMSCs and illustrates how the emerging shift from prohibition to regulation has affirmed the need for legislative intervention in this field. It concludes that since the future is on the side of regulation and not prohibition, legislation that furthers the policy agenda envisioned by the Defence Review 2012 may be the best tool to unlock the inhibitions of the past and create a viable climate for reframing the debate on domestic law governing private militarism in South Africa.

Description: Reports of witchcraft crimes are a staple feature in the South African tabloid newspaper, the Daily Sun. Instead of dismissing these sensational and seemingly implausible narratives, this paper examines them as ‘fictions’ through the lens of theory developed for the analysis of detective fiction. It draws on Huhn's (1987) model of the readerly relationships established by the narrative forms of the classical detective story and the hard-boiled novel in order to show how the reportage, together with its expected reception, reveals subliminal tensions within working-class black culture. Ironically, such a reading illustrates how the brazen and emotive nature of the tabloid text, which signals for some its untrustworthiness, perhaps comes closer to telling a ‘truth’ about contemporary South African society than the most ‘objective’ reports.

Description: A variety of nanoparticles (NPs), including FePt nanoparticles with Fe as the shell (2) or Pt as the shell (3), Pt NPs (4), and FePd (5) were synthesised, characterised and their effect on a zinc phthalocyanine (1) tetra-substituted with a pyridyl-oxy substituent studied using UV/Vis and fluorescence spectroscopy (including time correlated single photon counting, TCSPC). The nanoparticles were characterised using a number of techniques including UV/Vis and inductively coupled plasma-optical emission (ICP-OES) spectroscopies, transmission electron microscopy (TEM), differential scanning calorimetry (DSC), X-ray powder diffraction (XRD) and electron paramagnetic resonance (EPR) spectroscopy. Nanocomposites (NCs, 6,7) where the ZnPc (1) was used as the stabiliser, instead of oleic acid and or oleylamine, were also synthesised and characterised.

Description: This think piece captures some of the thinking that emerged in and through the Southern African Development Community (SADC) Regional Environmental Education Programme research programme. This research programme emerged over a five-year period (2008–2012) and involved ten southern African teacher education institutions from eight countries (see ‘Acknowledgements’). The research programme sought to understand what contributions environment and sustainability education could make to debates on educational quality and relevance. Issues of educational quality are high on the national agendas of governments in southern Africa, as it is now well known that providing access to schooling is not a sufficient condition for achieving educational quality. Educational quality is intimately linked to the processes of teaching and learning, but the concept of educational quality is not unproblematic in and of itself. It is, as Noel Gough (2005) noted many years ago, an ‘order word’ that shapes the way people think and practise. Our enquiries during this research programme involved a number of case studies (that were reported on in the Southern African Journal of Environmental Education (SAJEE) in 2008, and are again reported on in this edition of the SAJEE), but the programme also involved theoretical engagement with the concept of educational quality and relevance. This think piece helps to make some of this thinking and theoretical deliberation visible. The author of this think piece was also the leader of the regional research programme and was tasked with synthesising the theoretical deliberations that emerged from the research design which were found to be useful for guiding interpretations and deliberation on more detailed case studies undertaken at country level.

Description: Research methodology is significantly political and in this think piece I try to better understand the effect of this politicisation in the production of science. The main focus of the think piece is to identify the dominant methodological discourses and analyse them using techniques borrowed from post-structuralism. From this analysis, I suggest that methodological discourses are reproduced and normalised in much the same way as discourses of, for example, sexuality, and I give examples of this from my experience as a PhD student of environmental education. I also suggest that some transgressive methodologies, such as those associated with postmodernism or participatory research, despite purporting to empower, at times also disempower. Furthermore, all of the methodologies that I analyse are, in one way or another, ‘loaded’; they cloak their agendas. From this analysis, I move towards suggesting an alternative critical realist methodology for environmental education which is naked; its agendas are clearly stated, not least because this epistemology does not lend itself to deception. An important part of this critical realist conception of methodology is the idea of ‘meta-reflexivity’ in which truth is not vulgarly pragmatic or fideistic.

Description: Third order nonlinear optical properties were determined for phthalocyanine complexes 1–10 containing In, Ga and Zn central metals and tetra- or octa-substituted with benzyloxyphenoxy, phenoxy, tert-butylphenoxy and amino groups at peripheral or non-peripheral positions. The phthalocyanines were embedded in poly (methyl methacrylate) polymer in the presence of CdTe quantum dots. All complexes 1–10 were studied in the presence of CdTe quantum dots and embedded in poly (methyl methacrylate) to form thin films. Complex 3 tetrasubstituted with tert-butylphenoxy groups at non-peripheral positions was also studied in the presence of CdS, CdSe quantum dots, fullerenes, single walled carbon nanotubes. Third order nonlinear optical parameters generally increase for Pcs in the presence of CdTe quantum dots.

Description: This paper considers the application of GPU co-processors to accelerate the analysis of packet data, particularly within extremely large packet traces spanning months or years of traffic. Discussion focuses on the construction, performance and limitations of the experimental GPF (GPU Packet Filter), which employs a prototype massively-parallel protocol-independent multi-match algorithm to rapidly compare packets against multiple arbitrary filters. The paper concludes with a consideration of mechanisms to expand the flexibility and power of the GPF algorithm to construct a fully programmable GPU packet classification virtual machine, which can perform massively parallel classification, data-mining and data-transformation to explore and analyse packet traces. This virtual machine is a component of a larger framework of capture analysis tools which together provide capture indexing, manipulation, filtering and visualisation functions.

Description: Starting with the end result, the above transcription is the conclusion I came to after sitting with Laina Gumboreshumba for many hours, watching the videos she made during her recent doctoral research on the tshikona reedpipe dance of the Venda of Limpopo Province in the extreme north of South Africa. The transcription shown in Figure 2 is a skeleton version of the full pipe sound that contains all the information needed to grasp the structure of the sound and teach it or play it. There are always seven different pipes. A full tshikona group has far more than the seven pipes (nanga) shown, because all seven pipe numbers are doubled in every octave present in a group, so there may be up to four or more Pipe 1s, Pipe 2s, etc, of different sizes. All the Pipe 1s play the same pattern together, all the Pipe 2s etc. There are usually four octaves in all, with an incomplete octave of a few higher pitched pipes at the top (phalana). A popular size for a group according to group leaders (malogwane) is twenty eight pipes, which may include some pitch duplicates. A festive performance can number well over one hundred players. The music is heptatonic as you can see from the transcription, and hear for yourself from CD track 1 accompanying this issue of African Music. A chart showing the tuning is included as Figure 1 1 at the end of this article. This article does not address the pipe names; they are simply numbered Pipes 1 to 7, in the order of entry in Mr Netshivhale’s groups. The pipes are end-blown, closed tubes made of a special bamboo, or increasingly today of electrical or other tubing.

Description: Global climate change is correlated not only with variation in extinction rates, but also with speciation rates. However, few mechanisms have been proposed to explain how climate change may have driven the emergence of new evolutionary lineages that eventually became distinct species. Here, we discuss a model of range extension followed by divergence, in which the same climate oscillations that resulted in the extinction of coastal species across the Atlantic/Indian Ocean boundary in southwestern Africa also sowed the seeds of new biodiversity. We present evidence for range extensions and evolutionary divergence from both fossil and genetic data, but also point out the many challenges to the model that need to be addressed before its validity can be accepted.

Description: We investigate the ultrafast dynamics of the photoinduced electron transfer between surface-adsorbed indoline D149 dye and porous ZnO as used in the working electrodes of dye-sensitized solar cells. Transient absorption spectroscopy was conducted on the dye in solution, on solid state samples and for the latter in contact to a I−/I3− redox electrolyte typical for dye-sensitized solar cells to elucidate the effect of each component in the observed dynamics. D149 in a solution of 1:1 acetonitrile and tert-butyl alcohol shows excited-state lifetimes of 300±50 ps. This signature is severely quenched when D149 is adsorbed to ZnO, with the fastest component of the decay trace measured at 150±20 fs due to the charge-transfer mechanism. Absorption bands of the oxidized dye molecule were investigated to determine regeneration times which are in excess of 1 ns. The addition of the redox electrolyte to the system results in faster regeneration times, of the order of 1 ns.

Description: The convergence of previously distinct networks into an All-IP network has resulted in an increase in the number and diversity of devices, channels and communication networks available to users. This has increased the number commu-nication options available and is evidenced by the number of different communication devices owned and services subscribed to. How-ever, this has created complexities that call for proper methods to manage these diverse and in-compatible communication options. The objective of Unified Communication (UC) is to seamlessly integrate the dispar-ate communication channels into a device independent plat-form that can easily be managed by users. Due its focus on a largely urban and highly connected market, UC has not benefited marginalized communities. This paper discusses the design and implementation of Unicorn, a UC solution for a middleware software platform called Teleweaver which was designed to support the development of services for marginalized communities. The solution integrates services from a telecommunication container called Mobicents. It seamlessly amalgamates voice, data and video onto one device independent unified platform easily accessible by users.

Description: This paper presents evidence of establishment of a loricariid population in the Nseleni River in South Africa and uses a unified framework to determine its invasion stage. Specimens were identified morphologically as Pterygioplichthys disjunctivus (Weber 1991), but genetic barcoding results indicated close association with specimens that may have a hybrid history. The species was introduced into South Africa via the pet trade and the first record of introduction into the wild was in 2004. Samples collected in 2011 and 2012 demonstrated that there were multiple length cohorts in the population including juveniles (12–130 mm total length TL) and large (>300 mm TL) adult fish. Gonadal assessment of adults demonstrated the presence of reproduction capable specimens. The concurrent occurrence of mature adults and juvenile fish demonstrated establishment. Locality records indicate that P. disjunctivus has already spread between two rivers through an inter basin water transfer. Using a unified framework for invasions this invasion was categorized as a self-sustaining population in the wild with individuals surviving and reproducing a significant distance from their original point of introduction. Containment is suggested as potential management strategy.

Description: In the context of higher education in South Africa and drawing on the author's experience as a lecturer in two higher education institutions (HEIs), this article presents her attempts to bring together - and into balance - teaching, supervision and research in an endeavour to offer a transformative learning experience for her post graduate students. It does this by foregrounding student assessment in the Master of Education (MEd) degree in the field of Educational Leadership and Management (ELM) where the development of a half thesis, underpinned by research, stands as the evidence of success. The author suggests that the MEd (ELM) degree be conceptualised differently in order that the half thesis be permitted to gestate over a two-year period. Within this conceptualisation, she argues that inspired teaching and meaningful research is best attained through a community of learning approach which seeks to foreground participatory learning, the advancement of scholarly discourse and the development of student agency. Through the use of a case study, the author provides evidence to suggest that a range of authentic assessment strategies which are purposeful and in alignment with the teaching strategies, the content and the intended outcomes of the qualification being taught are essential. She further argues that well-crafted, formative, recursive and sustainable feedback is an essential part of the gestation process.

We've developed an initial appraisal of health journalism, locally and internationally, and we've created a normative framework that we hope will enable journalists and educators to have better discussions about what is meant by quality in health journalism. This framework will hopefully inform what kind of journalism education - degrees, short courses, topic guides, symposia - might promote higher levels of quality in reporting on medical science.

Description: In one of the interviews in Summertime, Martin, a former colleague, claims that he and the deceased John Coetzee felt their "presence" in South Africa "was legal but illegitimate," that it "was grounded in a crime, namely colonial conquest," which rendered them "sojourners, temporary residents, and to that extent without a home, without a homeland" (209-10). With this statement in mind, Maria J. Lopez argues that a sense of unbelonging underlies J. M. Coetzee's entire oeuvre, including the Australian fiction, and forms a kind of "imaginative and intellectual masterplot" (xii). ). It is this "narrative" that she traces in her monograph, starting with the early fiction and concluding with chapters on the fictionalised autobiographies and Australian fiction.

Description: The potential impact that data leakage can have on a country, both on a national level as well as on an individual level, can be wide reaching and potentially catastrophic. In January 2013, several South African companies became the target of a hack attack, resulting in the breach of security measures and the leaking of a claimed 700000 records. The affected companies are spread across a number of domains, thus making the leak a very wide impact area. The aim of this paper is to analyze the data released from the South African breach and to visualize the extent of the loss by the companies affected. The value of this work lies in its connection to and interpretation of related South African legislation. The data extracted during the analysis is primarily personally identifiable information, such as defined by the Electronic Communications and Transactions Act of 2002 and the Protection of Personal Information Bill of 2009.
