- Description: Wilma Cruise is probably best known for Strike the Woman Strike the Rock (2000), a public work produced collaboratively with Marcus Holmes which commemorates the march of women on the Union Buildings on 9 August 1956 to protest against the pass laws. This government commission tallies with Cruise's longstanding interest in feminism. Also, through its incorpora tion of sound, the written word and projections of imagery, Strike the Woman Strike the Rock coheres with an interest in combining a diversity of media and art forms that has been evident in her work during the last few years.

- Description: In this wide-ranging and impressive ac¬count of postapartheid writing, De Kock describes the “dizzingly heterogeneous corpus” (1) of South African literature after apartheid with the aim of describing its distinctive features and complexity. The methodology is straightforward. De Kock has chosen to read particular liter¬ary works in order to identify broader ideas and trends. To contextualise the study, De Kock deploys the key, perva¬sive notion of “transition”. The notion is variously defined as a “transformative shift from one ‘state’ to another” (2), a “popular mythology” in the “collective consciousness” (3), and as containing a counter-discourse of disillusionment or disorientation, which De Kock refers to as “‘plot loss’” (3). This “plot loss” becomes a central trope in the book to express the social and political chaos of the country, evident in various criminal manifestations of neo-colonialism such as neo-liberal economic policies, new forms of racism, and corruption.

- Description: As a student uprising tears across the fabric of post-apartheid campuses, the class of 2015 conjures Black Consciousness to articulate the pervasive epistemic assaults they endure daily at the ivory tower. As if time stood still, as though 1976 never left the scene, the philosophy of Black Consciousness is no lurking spectre; but it is an indispensable affirmation, a restorative life force that gives elaboration and credence to the grammar of black suffering. This is, therefore, a timely book.

- Description: Drawing on Bourdieu’s theories of field and capital, we examine the limitations that a journalism school at a prestigious university faces in making a meaningful contribution to the field within a developing country. In the postapartheid South African media landscape, journalism is under pressure both from global forces and a political imperative to address social justice. Given the heterogeneity of the journalistic field and the fact that what counts as capital in it is contested, the School of Journalism and Media Studies at Rhodes University attempts to redefine the parameters by inculcating a particular approach to and philosophy of journalism practice. While Rhodes wants to educate excellent (professional) journalists, it is guided by an overt political mission to cultivate a journalism that is not necessarily ‘in sync’ with the wider field. Ironically, most undergraduates come from the economic and cultural elite, with specific intentions to accumulate the capital which Rhodes bestows. Students are confronted with their privilege and with alternative ideas about the purpose of journalism, and are asked to make choices and take up positions. We consider whether this critical praxis approach is able to influence the ‘state of play’ – or the distribution of power – within the field.

- Description: Cyclodextrins (CDs) have widely been used as component of drug delivery systems. However unmodified cyclodextrins are associated with cytotoxicity and poor water solubility thus limiting their use in pharmaceutical industry. The cationic-β-cyclodextrin (Cat-β-CD) polymer cores were synthesized using β-CD, epichlorohydrin and choline chloride via a one-step polycondensation process. The main aim of this study was to synthesize hierarchical nanoflowers composed of cationic-β-CD as polymeric core along with alginate and chitosan “petals” (Cat-β-CD/Alg-Chi nanoflowers) as carriers for oral delivery of 5-Fluorouracil (5-FU) via an ionic-gelation technique. The drug loading capacity, particle size, zeta potential and surface morphology of the synthesized nanoflowers were determined. The prepared nanoflowers were formed with an average size of 300 nm and a zeta potential of + 9.90 mV with good encapsulation efficiency of up to 77.3%. In vitro release of 5-FU from the loaded nanoflowers showed controlled and sustained release compared to the inclusion complex alone. Cat-β-CD/Alg-Chi nanoflowers were assessed against L929 cells and found to be effectively inhibiting the growth of L929 cells in a concentration dependent manner.

- Description: Modelling transcription factor binding presents a number of challenges. In its simplest form, binding can be modelled by a consensus sequence but a number of factors including degeneracy of binding sites, alternative modes of binding and differences between artificially-constructed and in vivo DNA make modelling binding complex. In this paper we outline difficulties and report on progress with improving modelling of binding. We focus on improving measurement of binding models, a necessary prerequisite for finding better models.

- Description: Lantana camara L. (Verbenaceae) is one of the most problematic plant invaders in South Africa and has been targeted for biological control for over 50 years. Essential oil constituents which often change in response to insect herbivory are reported to play a crucial role in plant-insect interactions. However, nothing is known about the chemical profiles of essential oils of L. camara varieties in South Africa and how this changes under herbivory. Therefore, essential oils were collected using hydrodistillation from undamaged and insect-damaged leaves of four L. camara varieties and analysed using gas chromatography-mass spectrometry to elucidate their chemical profiles. A total of 163 compounds were identified from the undamaged leaves of the various L. camara varieties. Feeding by the biocontrol agent Falconia intermedia Distant (Hemiptera: Miridae) resulted in changes in the quality and quantity of chemical constituents of the essential oils. Only 75 compounds were identified from the insect-damaged leaves of L. camara varieties. Terpenes were the major components across the varieties, while caryophyllene, hexane, naphthalene, copaene and a-caryophyllene were common in all the varieties tested from both undamaged and insect-damaged leaves. Results from this study indicated the chemical distinctiveness of the Whitney Farm variety from other varieties. The changes in chemical concentrations indicated that feeding by the mirid on L. camara varieties causes an induction by either reducing or increasing the chemical concentrations. These inductions following the feeding by F. intermedia could be having a negative impact on the success of biological control against L. camara varieties. However, the focus of this paper is to report on the chemical baseline of L. camara varieties. Hence, comparisons of chemical compound concentrations of L. camara essential oils tested and the feeding-induced changes with respect to their quality and quantity are discussed.

- Description: Land-use intensification and declines in vegetative cover are considered pervasive threats to forests and biodiversity globally. The small extent and high biodiversity of indigenous forests in South Africa make them particularly important. Yet, relatively little is known about their rates of use and change. From analysis of past aerial photos we quantified rates of forest cover change in the Matiwane forests of the Wild Coast, South Africa, between 1942 and 2007, as well as quantified above- and belowground (to 0.5 m depth) carbon stocks based on a composite allometric equation derived for the area. Rates of forest conversion were spatially variable, with some areas showing no change and others more noticeable changes. Overall, the net reduction was 5.2% (0.08% p.a.) over the 65-year period. However, the rate of reduction has accelerated with time. Some of the reduction was balanced by natural reforestation into formerly cleared areas, but basal area, biomass and carbon stocks are still low in the reforested areas. The total carbon stock was highest in intact forests (311.7 ± 23.7 Mg C ha−1), followed by degraded forests (73.5 ± 12.3 Mg C ha−1) and least in regrowth forests (51.2 ± 6.2 Mg C ha−1). The greatest contribution to total carbon stocks was soil carbon, contributing 54% in intact forests, and 78% and 68% in degraded and regrowth forests, respectively. The Matiwane forests store 4.78 Tg C, with 4.7 Tg C in intact forests, 0.06 Tg C in degraded forests and 0.02 Tg C in regrowth forests. The decrease in carbon stocks within the forests as a result of the conversion of the forest area to agricultural fields was 0.19 Tg C and approximately 0.0003 Tg C was released through harvesting of firewood and building timber.

- Description: Unsubstituted zinc phthalocyanine (ZnPc), 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]-phthalocyanine (ZnTPPcQ) and Zn tetrasulfo phthalocyanine (ZnTSPc) were non-covalently (electrostatic and/or π–π interaction) attached to graphene quantum dots (GQDs) to form GQDs-Pc nanoconjugates. Relative to Pcs alone, the presence of GQDs improved the triplet quantum yields with the following values: GQDs-ZnPc (0.73), GQDs-ZnTPPcQ (0.76) and GQDs-ZnTSPc (0.67). Respective Förster resonance energy transfer (FRET) efficiencies were calculated to be 0.81, 0.80 and 0.28. However, singlet oxygen generating abilities of the as-synthesized nanoconjugates were relatively low due to the screening effect of GQDs and quenching in water. This study shows that, the type of Pc, loading and solvent used are among the vital properties to consider when constructing GQD-nanoconjugate systems with optimal triplet quantum yield properties and investigation of their physicochemical properties.

- Description: NaYF4:Er/Yb/Gd upconversion nanoparticles (UCNP) capped with amino groups were covalently attached to chloro aluminium tetrasulphonated phthalocyanine (ClAlTSPc) and chloro aluminium tetracarboxy phthalocyanine (ClAlTCPc). The conjugates were characterized using different techniques such as infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). There was a decrease in the intensity of fluorescence emission spectra of the UCNPs at 658 nm in the presence of the phthalocyanines. This decrease indicates an energy transfer between the donor UCNP and conjugated accepting phthalocyanine (Pc), due to Förster resonance energy transfer (FRET). FRET efficiencies of 18% and 21% for ClAlTSPc and ClAlTCPc, respectively, were obtained. Oxygen generation by ClAlTSPc following FRET was proved.

- Description: In this work, we characterized different phtalocyanine-capped core/shell/shell quantum dots (QDs) in terms of stability, ζ-potential, and size at various pH and ionic strengths, by means of capillary electrophoresis (CE), and compared these results to the ones obtained by laser Doppler electrophoresis (LDE) and dynamic light scattering (DLS). The effect of the phthalocyanine metallic center (Zn, Al, or In), the number (one or four), and nature of substituents (carboxyphenoxy- or sulfonated-) of functionalization on the phthalocyanine physicochemical properties were evaluated. Whereas QDs capped with zinc mono-carboxyphenoxy-phtalocyanine (ZnMCPPc-QDs) remained aggregated in the whole analyzed pH range, even at low ionic strength, QDs capped with zinc tetracarboxyphenoxy phtalocyanine (ZnTPPc-QDs) were easily dispersed in buffers at pH equal to or higher than 7.4. QDs capped with aluminum tetrasulfonated phthalocyanine (AlTSPPc-QDs) and indium tetracarboxyphenoxy phthalocyanines (InTCPPc-QDs) were stable in aqueous suspension only at pH higher than 9.0 due to the presence of functional groups bound to the metallic center of the phthalocyanine. The ζ-potential values determined by CE for all the samples decreased when ionic strength increased, being well correlated with the aggregation of the nanoconjugates at elevated salt concentrations. The use of electrokinetic methodologies has provided insights into the colloidal stability of the photosensitizer-functionalized QDs in physiological relevant solutions and thereby, its usefulness for improving their design and applications for photodynamic therapy.

- Description: There is growing recognition of the contribution of wild foods to local diets, nutrition, and culture. Yet disaggregation of understanding of wild food use by gender and age is limited. We used a mixed methods approach to determine the types, frequencies, and perceptions of wild foods used and sold by children in four villages in southern Malawi that have different levels of deforestation. Household and individual dietary diversity scores are low at all sites. All households consume one or more wild foods. Across the four sites, children listed 119 wild foods, with a wider variety at the least deforested sites than the most deforested ones. Older children can name more wild foods than younger ones. More children from poor households sell wild foods than from well-off households. Several reasons were provided for the consumption or avoidance of wild foods (most commonly taste, contribution to health, limited alternatives, hunger, availability, local taboos).

- Description: Stary Mwaba, an MFA candidate in the Arts of Africa and the Global South research team in the Fine Art Department, presented a paper on his installation, Chinese Cabbage, which was first displayed in his solo exhibition, Life on Mars, at the Künstlerhaus Bethanien in Germany in 2015. At the Africa–China symposium, Mwaba talked about his personal inroad into the Zambia–China debate, which draws from a family history of living along the Tazara Railway that was built by the Chinese in the 1960s, as well as the experience of his daughter attending a Chinese-run international school in Lusaka. Mwaba is currently expanding this research as part of his MFA studies at Rhodes by collecting oral narratives along the line of rail in Zambia and by addressing, through his painting practice, issues pertinent to the controversial copper slug known as Black Mountain in Kitwe.

- Description: publisher version , This article reports on the role and value of social reflexivity in collaborative research in contexts of extreme inequality. Social reflexivity mediates the enablements and constraints generated by the internal and external contextual conditions impinging on the research collaboration. It fosters the ability of participants in a collaborative project to align their interests and collectively extend their agency towards a common purpose. It influences the productivity and quality of learning outcomes of the research collaboration. The article is written by fourteen members of a larger research team, which comprised 18 individuals working within the academic development environment in eight South African universities. The overarching research project investigated the participation of academics in professional development activities, and how contextual, i.e. structural and cultural, and agential conditions, influence this participation. For this sub-study on the experience of the collaboration by fourteen of the researchers, we wrote reflective pieces on our own experience of participating in the project towards the end of the third year of its duration. We discuss the structural and cultural conditions external to and internal to the project, and how the social reflexivity of the participants mediated these conditions. We conclude with the observation that policy injunctions and support from funding agencies for collaborative research, as well as support from participants’ home institutions are necessary for the flourishing of collaborative research, but that the commitment by individual participants to participate, learn and share, is also necessary.

This paper identifies some of the ways in which post-development theory fails to adequately understand the African experience of development. In particular, I explore the difficulty that post-development theory confronts when faced with the continued desire on the part of many people in Africa for development.

- Description: In the developing world, one of the main obstacles to the realization of the potential of digital government in rendering services to citizens is the lack of access infrastructure. In this paper we present a model for the diffusion of Internet connectivity and access to computing infrastructure in rural communities in South Africa, through the aggregation of inde-pendent small and micro networks. The model is based on multi-year experimentation in the Siyakhula Living Lab, a long term joint venture between the Telkom Centres of Excellence hosted at Rhodes Universi-ty and the University of Fort Hare in South Africa. At the core of the model is the concept of ‘Broadband Island’, a high speed LAN realized through easy-to-deploy wireless technologies connecting groups of nearby schools. Each connected school, doubling as Digital Access Nodes for the community, hosts computing infrastructure in a serv-ers/thin clients configuration. Two schools belonging to the Broadband Island are then connected to the Internet with whatever technique makes sense within that specific geographical area: VSAT, microwave link, fibre etc. Each Broadband Island can be provisioned and support-ed by a variety of independent entities (such as Municipalities, Educa-tion Districts, NGOs, local action groups etc), possibly combined in con-sortia and in some cases using a Public Private Partnership format.

- Description: publisher version , Conservation and sustainable management of wetlands requires participation of local stakeholders, including communities. The Bigodi Wetland is unusual because it is situated in a common property landscape but the local community has been running a successful community-based natural resource management programme (CBNRM) for the wetland for over a decade. Whilst external visitors to the wetland provide ecotourism revenues we sought to quantify community benefits through the use of wetland goods such as firewood, plant fibres, and the like, and costs associated with wild animals damaging farming activities. We interviewed 68 households living close to the wetland and valued their cash and non-cash incomes from farming and collection of non-timber forest products (NTFPs) and water. The majority of households collected a wide variety of plant and fish resources and water from the wetland for household use and livestock. Overall, 53% of total household cash and non-cash income was from collected products, mostly the wetland, 28% from arable agriculture, 12% from livestock and 7% from employment and cash transfers. Female-headed households had lower incomes than male-headed ones, and with a greater reliance on NTFPs. Annual losses due to wildlife damage were estimated at 4.2% of total gross income. Most respondents felt that the wetland was important for their livelihoods, with more than 80% identifying health, education, craft materials and firewood as key benefits. Ninety-five percent felt that the wetland was in a good condition and that most residents observed the agreed CBNRM rules regarding use of the wetland. This study confirms the success of the locally run CBNRM processes underlying the significant role that the wetland plays in local livelihoods.

- Description: The Upper Zambezi, Kavango and Kwando are large floodplain rivers with substantial biodiversity, providing water and ecosystem services to a large tract of southern Africa. These rivers differ in hydrological regime. The Upper Zambezi and Kavango rivers are in flood for 4 months (March, April, May, June) while, in the Kwando River, floods are later and last for 1–2 months in July and August. The Upper Zambezi River has the largest annual flood pulse, followed by the Kavango River, while the Kwando River experiences small and unreliable floods. During years of exceptional flooding of the Upper Zambezi and Kavango rivers, the rivers are interconnected at peak flows and therefore share a common ichthyofauna. This provided a natural experiment to investigate the responses of fish communities comprised of the same species to differing flood regimes by comparing the fish assemblages and food‐web structures between rivers.
