- Description: This paper critically engages with the concept of development through an analysis of epistemological justice in education for sustainable development (ESD) and presents alternative strategies for adaptation of the concept in the South. Many definitional challenges still surround development studies. The paper draws on the work of Wolfgang Sachs (1999) who asserts that the notion of sustainability has been consumed by development, presenting a view of sustainability which challenges the current and dominant economically driven hegemonic development discourse in which sustainability has become embedded. Further useful perspectives for this paper are offered by Amartya Sen (2001) who refers to development as a form of freedom. Sachs (1999) maintains that global definitions of development cement the dominant hegemonic discourse of the leading North, which has resulted in an obfuscation of the epistemological contribution from the South. The paper argues that, in the integration of congruent and enabling conceptual frameworks, allowing epistemic justice and validating the lived experience of learners through socially responsive pedagogical frameworks, South Africa is beginning to respond to the global environmental crisis. At the core of the paper is the question of whether an African ethical position advances the attainment of sustainability objectives. The paper concludes by positing a shift in scholastic and social understandings of development, and redefining the term from a changing terrain which may seem immutable with the current environmental crisis.

- Description: The synthesis of three low symmetry A2B type Mn(III)triarylcorroles with meso-aryl substituents that provide push–pull electron-donating and -withdrawing properties is reported. An analysis of the structure-property relationships for the optical and redox properties has been carried out through a comparison with the results of theoretical calculations. The results demonstrate that A2B type Mn(III)triarylcorroles interact strongly with cell-free circulating tumor deoxyribonucleic acid (ctDNA) in solution, and that the interaction constants are enhanced when a stronger electron-donating substituent is introduced at the 10-position of the meso-triarylcorrole ligand.

- Description: The radioluminescence of synthetic quartz annealed at various temperatures up to 1000 °C is reported. The amplitude of the emission bands increases with annealing temperature. In addition, when samples are annealed at temperatures exceeding 700 °C, the intensity of the radioluminescence increases with duration of annealing. The corresponding emission spectra show seven emission bands at 2.04, 2.54, 2.77, 3.04, 3.40, 3.75 and 3.91 eV. The change in dominant emission band with annealing is consistent with annealing-induced variations in lifetimes determined previously from time-resolved optically stimulated luminescence spectra in the same samples.

- Description: publisher version , Globally higher education is situated in a supercomplex world (Barnett, 2000) that is constantly in a state of flux and subject to multiple pressures. This situation has been exacerbated in South African higher education that has been characterised by student protests in the last two years (2015–2016). One of the major causes for the recents protests, particularly in our institutional context, has been students’ anger that despite the official demise of apartheid and the end of colonial rule, some universities in South Africa are still attempting to be copies of Oxford and Harvard.

- Description: In Rehema Chachage's video installation, Kwa Baba Rithi Undugu (2010), sculptural objects representing old-fashioned transistor radios are mounted on the wall, side by side (Fig. 1). Embedded in each radio is a small video screen, which reveals a figure who stands in one place while the vertical line of the radio tuner crosses her body in search of the desired frequency (Figs. 2–3). A man's voice wafts in and out as it is periodically interrupted by unsolicited noise, revealing the difficulty of relating to others when sound is interrupted or there is an absence of voice. Voice, writes Chachage, is a “prerequisite for interlocution and the construction of discourse.” This work engages with the assertion that to “live means to participate in dialogue: to ask questions, to heed, to respond, to agree …” and to do so full heartedly with your “eyes, lips, hands, soul, spirit … whole body and deeds” (Bakhtin 1984:293).

From 360 BCE (Plato’s Philebus) to just the other day (Romanska’s Disability in Tragic and Comic Frame [2015]), this is an immense resource covering a lot of ground. The extracts don’t all apply specifically to theatre, though this is where the discussion begins, with the ancients. Later on, as new genres emerge, there are also entries relating to prose, film, story-telling and stand-up; but mainly, the writings have to do with laughter itself, and the role and function of comedy.

- Description: This research is the first of its kind to perform a successful side channel analysis attack on a symmetric encryption algorithm executing on a Raspberry Pi. It is demonstrated that the AES-128 encryption algorithm of the Crypto++ library is vulnerable against the Correlation Power Analysis (CPA) attack. Furthermore, digital processing techniques such as dynamic time warping and filtering are used to recovery the full en-cryption key. In Addition, it is illustrated that the area above and around the CPU of the Raspberry Pi leaks out critical and secret information.

- Description: In the greater landscape of South Africa’s traumatic past, the South African War of 1899-1902 is arguably “old history”, surpassed in time and importance by more pressing traumas. Moreover, because it was usurped by Afrikaner nationalism as a myth of national origin and used to justify claims of Afrikaner sovereignty, it is also often seen as “old Afrikaner history”: at best, an episode of limited relevance to the many South Africans effectively written out of this narrative; at worst, a platform for nostalgic hankering by a conservative few.

- Description: In this article I reexamine the ways in which certain contemporary artists based in Uganda problematize the narrative that the ruling National Resistance Movement (the NRM) party is the party of the rural poor (Cheeseman, Lynch, and Willis 2016) in their work while using it as a metaphor to inform their visual expression. I focus on the contest between tradition (imagined as a village) and modernity (imagined as a modern state), as well as the dilemma such a contest causes for a contemporary artist. Cornelius Adepegba (1995) argues that this dilemma influenced the African novel. Agreeing with Adepegba, Freeborn Odiboh (2009) observes that the same dilemma has shaped African visual artists, such as Abayomi Barber, and formal art education institutions like the Barber School in Nigeria; Odiboh then assesses the historical context in which this dilemma evolved as African nationalists struggled to forge postcolonial states based on a national consciousness amid competing ethnic, religious, and ideological interests.

- Description: While an interview could be described as a view among, between, betwixt, or in the midst of two subjects—from s'entrevoir (see each other); entre (between) and vue (view)—many interviews in art history are hierarchical not only in the sense of an interviewer “authoring” the material received from the respondent, but also in the sense of the theorist or writer shaping the ideas of the practitioner. As discussed in the First Word, “Situating Africa,” there is a tendency for writers in the “north” to theorize the professional practice of artists in the “south,” developing what Gordon Lewis (2006) refers to as a geography of reason. In their book Qualitative Interviewing: The Art of Hearing Data, Herbert J. Rubin and Irene S. Rubin (2012:7) develop the term “conversational partnership” to describe two or more participants who play an active role in shaping content as they cocreate meaning. This conversational partnership between two artists—one based in Uganda and the other based in South Africa—developed out of the publishing workshop at Rhodes University in June 2016, which aimed to approach the creation of knowledge from the perspective of “sideways learning” (see “Reaching Sideways, Writing Our Ways” in this issue). —Ruth Simbao.

- Description: While an interview could be described as a view among, between, betwixt, or in the midst of two subjects—from s'entrevoir (see each other); entre (between) and vue (view)—many interviews in art history are hierarchical not only in the sense of an interviewer “authoring” the material received from the respondent, but also in the sense of the theorist or writer shaping the ideas of the practitioner. As discussed in the First Word, “Situating Africa,” there is a tendency for writers in the “north” to theorize the professional practice of artists in the “south,” developing what Gordon Lewis (2006) refers to as a geography of reason. In their book Qualitative Interviewing: The Art of Hearing Data, Herbert J. Rubin and Irene S. Rubin (2012:7) develop the term “conversational partnership” to describe two or more participants who play an active role in shaping content as they cocreate meaning. This conversational partnership between two artists—one based in Uganda and the other based in South Africa—developed out of the publishing workshop at Rhodes University in June 2016, which aimed to approach the creation of knowledge from the perspective of “sideways learning” (see “Reaching Sideways, Writing Our Ways” in this issue). —Ruth Simbao.

- Description: Quartz is a common natural mineral with properties that make it amenable for application in radiation dosimetry using luminescence methods [1]. The luminescence properties of quartz including its sensitivity and luminescence lifetimes undergo notable changes when the quartz is annealed, and in particular, near its phase inversion temperatures of 573 and 867 oC [2, 3]. The physical processes leading up to the emission of luminescence in quartz may be investigated using time-resolved optical stimulation. The aim of this method is to separate in time the stimulation and emission of luminescence to enable measurement of time-resolved luminescence spectra which may be resolved into associated lifetimes, defined in this sense as the delay between stimulation and emission of luminescence [4, 5]. A number of such studies show that annealing defines the detailed distribution of lifetimes with measurement temperature as well as the irradiation-dependent characteristics of the lifetimes [3, 6]. In particular, it was noted [3] that spectra measured at certain temperatures could be accurately resolved into more than one component, a scenario that pointed to the possibility of involvement of multiple luminescence centers in the emission of luminescence from quartz. The aim of this work is to build on the findings described, specifically to study the influence of measurement temperature and irradiation on the principal and subsidiary luminescence lifetimes in natural quartz.

Release success of captive bred Cape Vultures (Gyps coprotheres) in the Magaliesberg Mountains, South Africa

- Description: The Cape Vulture, Gyps coprotheres, is currently classified as ‘endangered’. Endemic to southern Africa, its population has declined continuously over the past 40 years. The species is facing multiple anthropogenic threats. Notably, birds frequently collide with power lines and some cannot be released after treatment. This has led to the establishment of a captive breeding population with the hope that captive bred young can supplement wild populations and re-establish a now- abandoned breeding colony in the Magaliesberg Mountains, South Africa. This study aimed to follow the breeding behaviours of the captive colony and assess the appropriateness of chick rearing conditions. The study also aimed to monitor the behaviour, physical condition and dispersal of ten captive bred vultures after release in relation to their age. Behavioural observations of captive adult breeding and parental behaviours were conducted to establish whether chicks developed under comparable conditions to wild chicks. A high percentage of total colony copulation attempts (22 %) were extra-pair copulations. Four paired males formed ephemeral extra-pair relationships, two of which were homosexual. Chicks fledged earlier than wild chicks, on average at 128 days old. Wild and captive bred birds were observed at carcasses to compare competitive and feeding behaviours. Older birds, both wild and captive, fed the most efficiently. Preliminary evidence suggests females are more dominant and have higher display rates than males. Captive bred juvenile and four year old birds’ competitive and feeding behaviours (interaction rate, feeding rate, display rate, dominance, aggressiveness, and feeding efficiency) were the closest to, but still generally below, average values for same-aged wild birds. An index of body condition, body mass, and the prevalence of fault bars on the rectrices were used to assess their physical condition. After eight months, none of the ten birds had moved more than 8 km from the release site, nor had they foraged away from the vulture restaurant on site. Although altitude records of > 3100 m were recorded, their flight skills seemed inadequate. Future management considerations include the initiation of a pre-release exercise regime, the establishment of an acclimatization enclosure removed from the breeding site, and a varied or reduced post-release feeding schedule. Fledglings should be relocated and housed at the release enclosure until they are four years old.

- Description: The abortion decision-making process is embedded within overlapping power relations. Using a post-colonial feminist framework, we analyse South African and Zimbabwean women’s narratives regarding their abortion decision. As neighbouring countries, South Africa and Zimbabwe provide a useful counterpoint as they have common and differing social histories and very different abortion legislation. In our analysis, we unpick transversal commonalities and divergences in the discursive resources deployed by the women in their narratives in the two sites. Commonalities included the women feeling compelled to justify their abortion decision in the interactive interview space, an absence of a reproductive rights discourse, and the deployment of relationship embedded discourses in the justificatory work performed by the women. The ‘‘conjugalisation of reproduction’’, ‘‘imperative of good mothering’’, and ‘‘unstable partner relationships’’ discourses featured across both sites but the manner in which these were deployed differed. These discursive resources allowed the women to position themselves as making responsible decisions. The Zimbabwean women spoke of shame and hiding, a discursive resource that was explicitly absent in the South African women’s accounts. We conclude by arguing that our post-colonial feminist approach allows for a contextualised reproductive justice stance to abortion decision-making that identifies both transnational and context-specific power relations.

- Description: This article offers reflections on task design in the context of a Grade R (reception year) in-service numeracy project in South Africa. The research explores under what conditions, and for what learning purpose, a task designed by someone else may be recast and how varying given task specifications may support or inhibit learning, as a result of that recasting. This question is situated within a two-pronged task design challenge as to emerging gaps between the task designer’s intentions and teacher’s actions and secondly between the teachers’ intentions and students’ actions. Through analysing two teachers and their respective Grade R students’ interpretations of a worksheet task, provided to teachers in the project, we illuminate the way explicit constraints, in the form of task specifications, can be both enabling and constraining of learning. In so doing we recast this ‘double gap’ as enabling productive learning spaces for teacher educators, teachers and students.

- Description: This paper discusses how the climate change education/training needs of Park Managers, Ecologists, and Community Development Officers in Southern African Development Community (SADC) Transfrontier Conser-vation Areas (TFCAs) were established through contextual profiling. It subsequently analyses how a curriculum that was designed in response to a contextual profiling process was recontextualised during implementa-tion by the SADC Regional Environmental Education Programme (REEP), with support from the German Federal Enterprise for International Coop-eration (GIZ). The paper’s purpose is to trace the trajectory of contextual-ised curriculum development and implementation with a view to identify-ing how the twin concepts of contextual profiling and recontextualisation were utilised and lessons were learned. The paper has potential value for educators/ trainers interested in increasing the relevance of protected area workplace learning and its congruence to learners’ realities. It also has relevance for learning pathways in the environment and sustaninable development arena and elsewhere.

- Description: From Foreword by Dr Sizwe Mabizela, Vice-Chancellor: Many of the goals of our recently completed Institutional Development Plan have to do with retaining and improving our research and scholarly contribution as a university, and ensuring that we not only generate dependable knowledge, but that the knowledge that we create has a positive impact on the social and natural world around us. In summary, our goals are to 1. Maintain and strengthen our general formative degree offering and the research, teaching, and community engagement nexus which enables our students to access powerful knowledge; 2. Enable access to all academically-qualifying students and provide them with conditions which allow them to flourish as critical and engaged citizens; 3. Maintain and strengthen our unique institutional niche as a research-intensive university outside a major urban area; 4. Ensure financial and environmental sustainability practices through good governance, leadership and management; 5. Attract, nurture and retain staff of high-calibre and maintain an inclusive, welcoming, affirming and positive intellectual environment; 6. Provide relevant and appropriate academic infrastructure, equipment and facilities to support our academic project; and 7. Promote Rhodes University as an institution for the public good in local, provincial, national and international contexts. The plan calls upon all of us to re-imagine our University as one in which sustainability permeates every aspect of our academic endeavour, including an elevated sense of awareness and responsibility of our graduates for building sustainable communities. It calls upon us to ensure that we are simultaneously locally responsive and globally engaged. It calls upon us to work towards advancing social justice and do all that we can to restore the dignity and humanity of those who were treated as lesser beings by the previous dispensation. And it calls upon us to remind ourselves that our university does not exist in a vacuum. It exists within a social, cultural and economic milieu, and has an important role to play in lifting the standard of living of our local community.
