EDITORIAL

In an editorial in June last year I wrote that the question of the relevance of classical studies forAfrica has not yet been discussed in depth. Since then the changing political situation in SouthAfrica has made such a discussion even more urgent. It has become very popular to say thatSouth Africa should look to Africa, not Europe, in political as well as in cultural matters:"Eurocentric" has very nearly become a term of abus

DIE RESEPSIE VAN ENKELE AFRIKAANSE OPVOERINGS VAN GRIEKSE TRAGEDIES

In die bree kader van navorsing oor die resepsie van die Griekse tragedie word al hoe meer aandag aan die geskiedenis van die opvoerings van Griekse tragedies gegee. 'n Groeiende aantal artike!s en selfs boeke oor hierdie onderwerp word gepubliseer, waaronder die monumentale werk van Helmuth Flashar (1991), Die Enszenierung der Antike. Dit is 'n teken van die tyd dat The Cambridge Companion to Greek tragedy (Easterling 1997) 'n spesiale hoofstuk bevat met die titel "Tragedy in performance, nineteenth and twentieth century productions", waarby 'n baie interessante bibliografie aangeheg is, met verskeie titels wat vermeld word as "forthcoming"

ARISTOPHANES EN DIE TWEEDE BEDRYF VAN BREYTEN BREYTENBACH SE BOKL/ED: 'N VERKENNING

Breyten Breytenbach se drama Boklied het in die jongste tyd groot opspraak verwek, nie aIleen vanwee die tonele van naaktheid en seks nie, maar 66k vanwee daarvan. Die verwysingsveld is so breed dat die deursnee-toeskouer rue altyd die kloutjie by die oor kan bring rue. am hierdie rede het Hermien Dommisse (1998:13) op ietwat melodramatiese wyse verklaar: "Boklied kan die dood van die Afrikaanse toneel inlui." Sy motiveer dit so: "Boklied faa! as aanvaarbare toneel uit die staanspoor omdat Breytenbach as draers van sy woord toneelspelerverteenwoordigers uit die Griekse en Egiptiese mitologie kies wat vir die gehoor totale vreemdelinge is en met wie hulle hul rue kan identifiseer rue." Daarteenoor beweer Helize van Vuuren (Norval 1998:5) in haar professorale intreerede dat hierdie drama '''n inteIlektuele en kreatiewe inspuiting vir die nogal dormante Afrikaanse drama is". Sy wys ook op die Dionisiese gees van die drama

Die siening van die Griekse tragedie by Aristophanes

This article attempts to prove that the literary contest in Aristophanes’ Frogs is important as a reflection of contemporary literary discussions. A survey is given of the different aspects of Greek tragedy which are discussed and of the various and contradictory opinions which are expressed. The latter are not necessarily those of Aristophanes himself. In the 5th century B.C. the Greeks seem to have been mainly concerned with questions of style and with the moral influence of tragedy. With reference to the question of how much importance should be ascribed to the comic treatment of literary' matters, the view is put forward that The Frogs contains an exposition of genuine convictions about art. The parallel of Sheridan’s play The Critic confirms this conclusion. The present interpretation of Aristophanes is corroborated by the great influence The Frogs had on criticism right up to the 20th century

Challenges to creating primary care teams in a public sector health centre: a co-operative inquiry

Background: Effective teamwork between doctors and clinical nurse practitioners (CNP) is essential to the provision of quality primary care in the South African context. The Worcester Community Health Centre (CHC) is situated in a large town and offers primary care to the rural Breede Valley Sub-District of the Western Cape. The management of the CHC decided to create dedicated practice teams offering continuity of care, family-orientated care, and the integration of acute and chronic patients. The teams depended on effective collaboration between the doctors and the CNPs. Methods: A co-operative inquiry group, consisting of two facility managers, an administrator, and medical and nursing staff, met over a period of nine months and completed three cycles of planning, action, observation and reflection. The inquiry focused on the question of how more effective teams of doctors and clinical nurse practitioners offering clinical care could be created within a typical CHC. Results: The CHC established three practice teams, but met with limited success in maintaining the teams over time. The group found that, in order for teams to work, the following are needed: A clear and shared vision and mission amongst the staff. The vision was championed by one or two leaders rather than developed collaboratively by the staff. Continuity of care was supported by the patients and doctors, but the CNPs felt more ambivalent. Family-orientated care within practices met with limited success. Integration of care was hindered by physical infrastructure and the assumptions regarding the care of "chronics". Enhanced practitioner-patient relationships were reported by the two teams that had staff consistently available. Significant changes in the behaviour and roles of staff. Some doctors perceived the nurse as an "assistant" who could be called on to run errands or perform tasks. Doctors perceived their own role as that of comprehensively managing patients in a consultation, while the CNPs still regarded themselves as nurses who should rotate to other duties and perform a variety of tasks, thus oscillating between the role of practitioner and nurse. The doctors felt responsible for seeing a certain number of patients in the time they were available, while the CNPs felt responsible for getting all the patients through the CHC. The doctors did not create space for mentoring the CNPs, who were often seen as an intrusion and a threat to patient privacy and confidentiality when requesting a consultation. For the CNPs, however, the advantage of practice teams was considered to be greater accessibility to the doctor for joint consultation. The identification of doctors and CNPs with each other as part of a functioning team did not materialise. Effective management of the change process implied the need to ensure sufficient staff were available to allow all teams to function equally throughout the day, to be cognisant of the limitations of the building design, to introduce budgeting that supported semi-autonomous practice teams and to ensure that the staff were provided with ongoing opportunities for dialogue and communication. The implications of change for the whole system should be considered, and not just that for the doctors and nurses. Conclusion: Key lessons learnt included the need to engage with a transformational leadership style, to foster dialogical openness in the planning process and to address differences in understanding of roles and responsibilities between the doctors and the CNPs. The unreliable presence of doctors within the practice team, due to their hospital duties, was a critical factor in the breakdown of the teams. The CHC plans to further develop practice teams, to learn from the lessons so far and to continue with the co-operative inquiry

Geographic range extension of Speke's Hinge-back Tortoise Kinixys spekii Gray, 1863

Kinixys spekii has a wide distribution range across sub-Saharan Africa, having been reported from Angola, Botswana, Burundi, the Democratic Republic of the Congo, eSwatini, Kenya, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. Kinixys spekii inhabits savannah and dry bushveld habitats and was previously considered an inland species. However, recent records suggest a more extensive geographical distribution. Here, we provide genetically verifed records for Angola, South Africa, and Mozambique, and discuss reliable sightings for Rwanda. These new records extend the range signifcantly to the east and west, and provide evidence for the occurrence of this species along the coast of the Indian Ocean in South Africa and Mozambique.© 2019 Ihlow et al.

A Systematic Review of the Critical Factors for Success of Mobile Learning in Higher Education (University Students\u27 Perspective)

The phenomenon of the use of a mobile learning (m-Learning) platform in educational institutions is slowly gaining momentum. However, the enthusiasm with which mobile phones have been welcomed into every aspect of our lives is not yet apparent in the educational sector. To understand the reason, it is important to understand user expectations of the system. This article documents a systematic review of existing studies to find the success factors for effective m-Learning. Our systematic review collates results from 30 studies conducted in 17 countries, where 13 critical success factors were found to strongly impact m-Learning implementation. Using these results within the framework of the diffusion of innovation model for innovation adoption and the critical success factors together help us see what aspects of the innovation decision process are the likely causes of the reduced take-up of m-Learning by university students

Revival of the magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR

New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March 19 and April 5. The radio flux density, while variable, is approximately 100x larger than during its dormant state. The X-ray flux one month after reactivation was at least 800x larger than during quiescence, and has been decaying exponentially on a 111+/-19 day timescale. This high-flux state, together with a radio-derived rotational ephemeris, enabled for the first time the detection of X-ray pulsations for this magnetar. At 5%, the 0.3-6 keV pulsed fraction is comparable to the smallest observed for magnetars. The overall pulsar geometry inferred from polarized radio emission appears to be broadly consistent with that determined 6-8 years earlier. However, rotating vector model fits suggest that we are now seeing radio emission from a different location in the magnetosphere than previously. This indicates a novel way in which radio emission from magnetars can differ from that of ordinary pulsars. The torque on the neutron star is varying rapidly and unsteadily, as is common for magnetars following outburst, having changed by a factor of 7 within six months of reactivation.Comment: Published in ApJ (2018 April 5); 13 pages, 4 figure

Accurate ab initio spin densities

We present an approach for the calculation of spin density distributions for molecules that require very large active spaces for a qualitatively correct description of their electronic structure. Our approach is based on the density-matrix renormalization group (DMRG) algorithm to calculate the spin density matrix elements as basic quantity for the spatially resolved spin density distribution. The spin density matrix elements are directly determined from the second-quantized elementary operators optimized by the DMRG algorithm. As an analytic convergence criterion for the spin density distribution, we employ our recently developed sampling-reconstruction scheme [J. Chem. Phys. 2011, 134, 224101] to build an accurate complete-active-space configuration-interaction (CASCI) wave function from the optimized matrix product states. The spin density matrix elements can then also be determined as an expectation value employing the reconstructed wave function expansion. Furthermore, the explicit reconstruction of a CASCI-type wave function provides insights into chemically interesting features of the molecule under study such as the distribution of $\alpha$- and $\beta$-electrons in terms of Slater determinants, CI coefficients, and natural orbitals. The methodology is applied to an iron nitrosyl complex which we have identified as a challenging system for standard approaches [J. Chem. Theory Comput. 2011, 7, 2740].Comment: 37 pages, 13 figure
