- Description: Is crime fiction the new 'political novel' in South Africa? Why did the apartheid censors disapprove of crime fiction more than any other genre? Crime fiction continues to be a burgeoning literary category in post-apartheid South Africa, with more new authors, titles and themes emerging every year. This book is the first comprehensive survey of South African crime fiction. It provides an overview of this phenomenally successful literary category, and places it within its wider social and historical context. The authors specialise in both literary studies and print culture, and this combination informs a critical analysis and publishing history of South African crime fiction from the nineteenth century to the present day. The book provides a literary lineage while considering different genres and sub-genres, as well as specific themes such as gender and eco-criticism. The inclusion of a detailed bibliography of crime fiction since the 1890s makes A Survey of South African Crime Fiction an indispensable teaching and study aid

- Description: The optically stimulated luminescence from carbon-doped aluminium oxide (α-Al2O3:C) displays a peak with time under certain measurement conditions. In this paper, we present factors that influence the peak-like shape of continuous-wave optically stimulated luminescence (CW-OSL) signal. The report is based on the experimental study of OSL signals obtained by stimulation of very deep traps in α-Al2O3:C. Methods exploiting post-irradiation annealing, variable dose and temperature dependent OSL measurements were used in the investigation. It is found that the rising part of the CW-OSL peak is obtained when the rate of retrapping at the most optically active trap (main trap) exceeds the rate of direct radiative recombination following optical release of charges from all optically active traps. This is possible if, during optical stimulation, the primary trap responsible for OSL i.e. the main trap, is substantially unoccupied and the very deep, donor traps are substantially filled up. The rate of charge retrapping itself is deduced to depend on the occupancy of the acceptor traps i.e. shallow, main and secondary traps; concentration of charge carriers in the very deep, donor traps; the post-irradiation annealing temperature and the temperature at which the OSL is measured.

- Description: It is known that when α-Al2O3:C is exposed to excessive amounts of ionising radiation, defects are induced within its matrix. We report the influence of radiation-induced defects on the thermoluminescence (TL) and optically stimulated luminescence (OSL) measured from α-Al2O3:C after irradiation to 1000 Gy. These radiation-induced defects are thermally unstable in the region 450–650 °C and result in TL peaks in this range when the TL is measured at 1 °C/s. Heating a sample to 700 °C obliterates the radiation-induced defects, that is, the TL peaks corresponding to the radiation induced defects are no longer observed in the subsequent TL measurements when moderate irradiation doses below 10 Gy are used. The charge traps associated with these radiation-induced defects are more stable than the dosimetric trap when the sample is exposed to either sunlight or 470-nm blue light from LEDs. TL glow curves measured following the defect-inducing irradiation produce a dosimetric peak that is broader and positioned at a higher temperature than observed in glow curves obtained before the heavy irradiation. In addition, sample sensitization/desensitization occurs due to the presence of these radiation-induced defects. Furthermore, both the activation energy and the kinetic order of the dosimetric peak evaluated when the radiation-induced defects are present in the sample are significantly lower in value than those obtained when these defects are absent. The radiation-induced defects also affect the shape and total light sum of the OSL signal as well as the position and width of the resultant residual phototransferred thermoluminescence main peak.

- Description: A comprehensive kinetic analysis of the glow peaks in α-Al2O3:C,Mg is reported. A thermoluminescence glow curve measured at 1 °C/s after beta irradiation to 1 Gy shows a high intensity peak hereafter referred to as the main peak at 161 °C and six lower intensity secondary peaks at 42, 72, 193, 279, 330, 370 °C respectively. For ease of reference, the secondary peaks are labelled as I, II, IV, V, VI and VII respectively and the main peak denoted peak III. Kinetic analysis of the glow peaks has been carried out using the initial rise, whole glow peak, peak shape, variable heating rate and glow curve deconvolution methods as well as by way of phosphorescence. Using Tm-Tstop, Tm-dose and phosphorescence analyses, the order of kinetics of the peaks has been evaluated as first order. Analysis by the peak shape, whole glow peak and deconvolution methods produce the same conclusion. The activation energy of peaks I through VII are calculated as ~0.83, 0.96, 1.37, 1.20, 1.15, 1.61 and 1.94 eV respectively. The frequency factors for all the peaks are of the order of 109 to 1014 s−1. The question of thermal quenching affecting the peaks was considered. The peaks III, IV and V, the only ones that could be conveniently studied in this regard, were found to be affected by thermal quenching. The activation energy for thermal quenching was calculated for peak III as 0.96±0.03 eV, for peak VI as 0.95±0.07 eV and for peak V as 1.26±0.08 eV. The thermal quenching phenomenon has been discussed with reference to F+ and F centres. An energy band model has been developed to discuss the luminescence mechanisms in α-Al2O3:C,Mg in light of finding in this work.

- Description: The kinetic analysis of thermoluminescence of beta-irradiated SrAl2O4:Eu2+,Dy3+ is reported. The glow-curve is dominated by an apparently-single peak. It has been demonstrated using a number of tests including partial dynamic-heating, isothermal heating, phosphorescence and, the effect of fading, that the peak and the glow-curve consists of a set of closely-spaced peaks. In view of the peak being complex, its first few components were abstracted and analysed and for comparison, the peak was also analysed assuming it is genuinely single.

- Description: The luminescence sensitivity of α-Al2O3:C and α-Al2O3:C, Mg is of interest because of the contemporary use of these materials in dosimetry related applications. We report investigations concerning the change in sensitivity of thermoluminescence (TL) and optically stimulated luminescence (OSL) from α-Al2O3:C and α-Al2O3:C, Mg with re-use. The study was carried out on a set of un-annealed samples and others annealed at 700 and 900 °C. The TL and OSL sensitivity in α-Al2O3:C and α-Al2O3:C, Mg was found to increase with sample re-use whether the intensity was monitored as peak area or peak height for the main TL peak or, in the case of OSL, as the maximum intensity or the area under a decay curve. The fractional increase in area under either the main TL peak or the OSL decay curve exceeds that of the TL peak height or maximum OSL intensity when samples are re-used. However, when un-annealed samples are used, any increase in TL peak height or peak area per measurement is less than observed in annealed samples. It is also interesting to note that the change in maximum OSL intensity or OSL area is minimal for samples annealed at 900 °C. In general, the TL sensitivity in α-Al2O3:C increases more than that in α-Al2O3:C, Mg with re-use. On the other hand, the OSL sensitivity in α-Al2O3:C, Mg increases more than that in α-Al2O3:C with re-use. These findings suggest that it is advisable to take into account the fractional increase in sensitivity per measurement when one uses α-Al2O3:C as a TL dosimeter and α-Al2O3:C, Mg as an OSL dosimeter.

- Description: Preface: Since 1996 the number of students enrolled for Master’s study in South Africa has more than doubled, while doctoral enrolments have almost tripled (Cloete, Mouton and Sheppard 2015). Such enormous growth has had major implications for supervision, especially in a context where only 39% of academics have doctorates themselves. If South Africa is to come close to the National Development Plan target of 5 000 doctoral graduates per year by 2030, the pressure on supervisors is likely to continue apace. But supervision is of course not simply a matter of applying technical skills to churn out highly competent postgraduate scholars. It is a teaching craft coupled with research acumen and deep personal commitment. This book reflects on how a range of supervisors are making sense of this complex endeavour. The Strengthening Postgraduate Supervision book brings together 15 chapters written by 18 academics from 16 disciplines in 11 institutions. The authors work across all three institutional types found in higher education in South Africa: traditional universities, comprehensive universities and universities of technology. Through this rich array of contributions, supervision is presented never as a ‘best practice’ to be generically implemented but rather as a nuanced pedagogy to be nurtured through critical reflection. The chapters mix theoretical considerations of the postgraduate process and personal narratives of supervision practice. Most of the authors can be described as emerging supervisors, with a few contributions from more experienced supervisors, but all have in common a deep desire to forge inclusive environments that foster meaningful postgraduate research and nurture a new generation of scholars. It is through the sharing of these academics’ concerns and constraints, competencies and celebrations that this book adds to our understanding of postgraduate supervision in South Africa.

- Description: The relationship of pulse-width, lifetime and measurement temperature in describing intensity of time-resolved luminescence optically stimulated at 470 nm from α-Al2O3:C is reported. The change of luminescence intensity with stimulation temperature is discussed in terms of the signal integrated over a complete time-resolved luminescence spectrum or in terms of ratios of the signal emitted either during or after pulsed stimulation to the total signal obtained per spectrum. The temperature-induced change in these parameters depends on whether the pulse-width is less or more than the luminescence lifetime. This is because the lifetime in α-Al2O3:C varies with measurement temperature. We have developed and applied new models to distinguish thermal assistance from different traps and to use this information as an additional means to analyse thermal quenching by using the luminescence intensity integrated from time-resolved spectra. Using a model based on use of the throughput, the activation energy for thermal assistance was determined for the shallow trap as 0.054±0.001 eV and as 0.53±0.03 eV for the main trap. The activation energy for thermal quenching was then evaluated using luminescence yield during the pulse as 1.09±0.01 eV and as 1.12±0.01 eV using the throughput after the pulse. Using the new analytical method based on integrated intensity, the activation energy for thermal quenching was found as 1.00±0.07 eV. These values are self-consistent and show that the methods for analyzing temperature-induced changes in intensity and the attendant thermal effects, such as thermal assistance can be successfully applied. We have also reported a general mathematical model that accounts for the temperature-dependence of time-resolved luminescence from α-Al2O3:C. The luminescence study was complemented by investigation of the phase and composition heterogeneity of the samples.

- Description: We report the thermoluminescence glow curves of beta irradiated single crystal α-Al2O3:C,Mg after annealing at 700 and 900 °C. A glow curve measured at 1 °C/s from samples irradiated to 1 Gy following annealing at 700 and 900 °C shows a high intensity peak at 163 °C and seven secondary peaks of weaker intensity at 43, 73, 100, 195, 280, 329 and 370 °C. Comparing the position of the peaks in the annealed samples with those in an un-annealed one, it is observed that the peak at 100 °C appears only after annealing at and above 700 °C. Kinetic analysis of this annealing-induced peak was carried out using the initial rise, whole glow peak, peak shape, curve fitting and variable heating rate methods. The order of kinetics of the peak was determined as first order using various methods including the Tm-Tstop technique and the dependence of Tm on irradiation dose. The activation energy of the peak is about 1.01 eV and the frequency factor of the order of 1012 s−1. The peak was found to be affected by thermal quenching in analysis based on change of peak intensity with heating rate. The activation energy of thermal quenching was evaluated as 1.06 ± 0.08 eV. We speculate that the annealing-induced peak is due to formation of a new electron trap after destruction of the F22+(2 Mg) centre when the sample is annealed at 700 °C. The annealing-induced peak fades with storage between irradiation and measurement. It was also concluded that electrons from traps corresponding to secondary peaks get re-trapped at the main electron trap.

- Description: Thermal assistance and thermal quenching are two independently acting thermodynamic phenomena that simultaneously affect the stimulation of luminescence. We have studied thermal assistance to luminescence optically stimulated from α-Al2O3:C,Mg. Since thermal assistance causes only a minor change in the luminescence intensity, measurements were made after the sample had been pre-exposed to stimulating light to reduce its intensity significantly, that is, in the slow component of its decay curve. The luminescence intensity was monitored as a function of measurement temperature between 30 and 130 °C. The intensity goes through a peak at 60 °C due to competing effects of thermal assistance and thermal quenching. The initial increase of intensity is attributed to dominant thermal assistance whereas the subsequent decrease of intensity is ascribed to dominant thermal quenching. The activation energy for thermal assistance was calculated for the main electron trap of an un-annealed sample as 0.324 ± 0.020 eV and in a sample annealed at 900 °C as 0.416 ± 0.028 eV. Implications of such differences in the value of the activation energy for thermal assistance are considered.

- Description: publisher version , From Introduction: This chapter examines the importance of orality in rural communities using the paradigm of technauriture, which describes how technology, auriture2and literature intersect to transmit educational and other messages within communities. It uses oral literary research that has been conducted in the Eastern Cape region to show how technology can aid the data collection process, and how this technology can return such information to the communities from which it comes. This chapter also explores the process of orality fostered by community meetings, oral histories, oral poetry, beadwork, music and story-telling, and how this culture interacts with the recording process facilitated by modern technology. It will also consider the return of recorded oral material to educational and archival circles. These objectives are pursued using empirical data collected at Tshani near Port St. Johns, an area falling within the Mankosi tribal authority in the Eastern Cape Province of South Africa. They are also considered in relation to the work of oral poet, Bongani Sitole who lived in Mqhekezweni village near Qunu and Mthatha, as well as against the backdrop of research conducted in Keiskammahoek, and at the Broster Beadwork Collection, now housed at Walter Sisulu University in Mthatha.

- Description: We report the thermoluminescence of SrAl2O4:Eu2+,Dy3+ measured in the ultra-violet region of the spectrum between 300 and 400 nm. Complementary measurements of X-ray excited optical luminescence confirm emission bands of stimulated luminescence in this region. As a further test, optically stimulated luminescence was also measured in this region. The glow curve measured at 1 °C s−1 following irradiation to various doses appears simple and single but is in reality a collection of several components. This was shown by results from the Tm-Tstop method on both ends of the peak, application of thermal cleaning beyond the peak maximum as well as the dependence of the peak on fading. The latter shows that new peaks appear as preceding ones fade. Kinetic analysis of some of the main peaks was carried out giving an activation energy of 0.6 eV. The implication of the results on measurement of phosphorescence, interpretation of dose response and fading is discussed.

- Description: Publisher version , Teaching Excellence Awards have raised the profile of teaching as a scholarly project. There are however a number of questions about what constitutes teaching excellence and how ‘excellence’ is understood in current higher education. In a post-colonial South Africa, where significant injustices permeate our society, we question whether excellence can be understood in a generic manner. Furthermore, we argue that as universities are a public good, teaching excellence needs to explicitly attend to the ways in which universities contribute to broad goals of transformation and inclusivity. We analysed data from the national Teaching Excellence Awards and 13 South African universities’ awards to interrogate the discourses that underpin ‘excellence’ in this context of social inequality. We found that while the awards have gone some way to enhancing the position of teaching in institutions, ‘excellence’ was largely articulated in fairly generic ways which failed to take into account the enablements and constraints of the discipline and the institution. Furthermore, the guidelines and criteria privilege a decontextualised notion of excellence that seeks a ‘gold standard’ and validates performativity, rather than a contextualised response to the needs of the students.

- Description: The social and economic significance of the doctorate is recognised across the world, as doctoral candidates are considered to be key contributors to the knowledge society by contributing to socio-economic development through innovation (Barnacle 2005; Taylor 2012). Doctoral students – regardless of their discipline – are expected to take part actively in the knowledge creation process at universities, and this is especially important for those who will remain in academia and continue to contribute in this way.1 But knowledge creation is a complex process. Knowledge creation at the doctoral level and beyond requires a comprehensive understanding of relevant knowledge, sound judgment, and the ability to advise with insight. Doctoral learning also includes aspects such as abstract reasoning, the ability to conceptualise, and problem solving. Thus, through the original contribution candidates are expected to create during the doctorate, they are supposed to become experts in their chosen field of study. This process has been described by Evans (2014) as disciplinary acculturation. Various authors (for example Danby & Lee 2012; Lin & Cranton 2005; Manathunga & Goozée 2007) point out that this process of becoming an expert is by no means easy or straightforward. Rather, developing as a scholar is a lifelong process in which moving from a novice to an expert is an essential rite of passage into academic practice (Dreyfus & Dreyfus 1986). Benmore (2014) states that for those pursuing academic careers, it involves coming to know, but also coming to be an academic. Such a process of becoming doctorate implies movement over time, progression, and transformation (Barnacle, 2005).

- Description: The thermoluminescence of beta irradiated K-Mg-Al-Zn fluorophosphate glass is reported. A glow-curve corresponding to 10 Gy measured at 1 °C/s shows two peaks, a weaker-intensity one at 70 °C and a more prominent one at 235 °C, the subject of this report. The main peak was observed to fade with delay between irradiation and measurement and specifically, by 11% in 15 h. Its dose response is superlinear in the dose range 1–190 Gy although the change was linear for the initial 10 Gy. Regarding kinetic analysis, the activation energy of the higher temperature peak was evaluated as 1.31 eV and that of the lower temperature peak was found as 0.47 eV. It was also noted that the main peak is affected by thermal quenching with an activation energy for thermal quenching equal to 1.37 eV. It is proposed that the mechanism associated with the thermoluminescence in K-Mg-Al-Zn fluorophosphate glass is that electrons trapped by the metal cations are released during heating and then recombine with holes at oxygen sites.

- Description: Victims of crimes against humanity perpetrated during Kenya’s post-2007 conflicts may feel aggrieved by the International Criminal Court’s discontinuance of all Kenya cases without having found the suspects either culpable or non-culpable. Neither did the suspects benefit from acquittals. Unprecedentedly, Ruto and Sang’s charges were vacated at half-time. Cases against other suspects were withdrawn. Given the circumstances which led to the ICC’s intervention in the Kenyan situation, this paper argues that in lieu of either quantitative or qualitative studies, arguments of various proxy approaches for evaluating judicial performance, are problematic. Neither judicial independence, rule-compliance, community of purpose, nor even institutional design, adequately measure judicial performance. Besides interrogating limitations of using such proxies, the paper appraises the merits of constructing a modified version of the goal-based approach. It will demonstrate that by incorporating both process-oriented as well as strategic constituency models, a more dynamic evaluative methodology can be developed for measuring the ICC’s performance in the Kenya cases.

- Description: Despite the popularity of local economic development (LED) as a job creation and economic growth strategy in South Africa, many LED projects have not proved to be sustainable in the long-run, especially where human systems interact with biological ones. This article examines the relationship between sustainability and LED within the context of the emerging honeybush tea industry in the Eastern Cape. Data were gathered from provincial as well as local government policy documents and reports, and via key informant interviews. The data were analysed using Connelly’s [(2007). Mapping sustainable development as a contested concept. Local Environment, 12 (3), 259–278] three pronged approach to sustainable development as a lens through which to view the local industry. Findings showed that the industry offers many opportunities for development, including job creation in poorer, rural households; sustainable wild harvesting using a permit system; commercial cultivation; potential to develop social capital; potential for community-based LED; and product diversification. However, there are also corresponding challenges: There is currently no reliable data on the maximum sustainable yield, which is needed to guide quota allocations for entrepreneurial harvesters harvesting from wild stocks; possible biodiversity loss; and enforcing the permit scheme is proving difficult in remote rural areas.

- 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.
