A Companion to Classical Receptions
A. De Villiers
Akroterion , 2012, DOI: 10.7445/53-0-44
Abstract: This recent addition to the excellent Blackwell Companions series looks at the various forms of classical reception currently being researched as well as those deemed to have future importance. The diversity and volume of the themes and approaches contained in this book are truly impressive. As Hardwick and Stray state in their introduction, this collection “has been constructed on the basis that the activators of reception are many and varied and that we all gain from encountering examples from outside our own immediate areas of knowledge” (p. 4). Throughout the book they stay true to this motto and traditional approaches to classical reception are not given prominence over more recent (sometimes contentious) approaches such as film studies, cultural politics and photography. The same goes for the various cultures involved and there is even a chapter on Greek drama in South Africa.
THE LAODAMIA SIMILE IN CATULLUS 68: REFLECTIONS ON LOVE AND LOSS
A. De Villiers
Akroterion , 2012, DOI: 10.7445/53-0-40
Abstract: In Catullus’ poem 68 he compares his beloved, generally identified as Lesbia, to the mythological figure of Laodamia in a long simile covering 57 lines. Laodamia epitomises the ideal wife, both passionate and loyal and so much in love with her new husband Protesilaus, that she cannot bear to live without him. Therefore she appears to be the perfect comparison for a beloved woman as seen through the eyes of her infatuated lover. But at a closer reading of the poem the interpretation of the simile turns out to be much more complex than that. Lesbia is not loyal and she is not Catullus’ wife. He admits both these facts near the end of the poem. Furthermore, Laodamia turns out to have two referents: Lesbia and the poet himself. In this paper I will be looking at various interpretations of the Laodamia simile as well as adding my own thoughts on this complex and beautiful poem.
The development, implementation and evaluation of a short course in objective structured clinical examination (OSCE) skills
A De Villiers, E Archer
South African Family Practice , 2012,
Abstract: Background: Objective structured clinical examination (OSCE) examiner training is widely employed to address some of the reliability and validity issues that accompany the use of this assessment tool. An OSCE skills course was developed and implemented at the Stellenbosch Faculty of Health Sciences and its influence on participants (clinicians) evaluated. Method: Participants attended the OSCE skills course, which included theoretical sessions concerning topics such as standard setting, examiner influence and assessment instruments, as well as two staged OSCEs, one at the beginning and the other at the end of the course. During the latter, each participant examined a student role-player performing a technical skill while being video recorded. Participants’ behaviour and assessment results from the two OSCEs were evaluated, as well as the feedback from participants regarding the course and group interviews with student role players. Results: There was a significant improvement in inter-rater reliability as well as a slight decrease in inappropriate examiner behaviour, such as teaching and prompting during assessment of students. Furthermore, overall feedback from participants and perceptions of student role players was positive. Conclusions: In this study, examiner conduct and inter-rater reliability was positively influenced by the following interventions: examiner briefing, involvement of examiners in constructing assessment instruments, as well as examiners viewing (on DVD) and reflecting on their assessment behaviour. This study proposes that the development and implementation of an OSCE skills course is a worthwhile endeavour in improving validity and reliability of the OSCE as an assessment tool.
Recent Advances in the Discovery of Haem-Targeting Drugs for Malaria and Schistosomiasis
Katherine A. De Villiers,Timothy J. Egan
Molecules , 2009, DOI: 10.3390/molecules14082868
Abstract: Haem is believed to be the target of some of the historically most important antimalarial drugs, most notably chloroquine. This target is almost ideal as haem is host-derived and the process targeted, haemozoin formation, is a physico-chemical process with no equivalent in the host. The result is that the target remains viable despite resistance to current drugs, which arises from mutations in parasite membrane transport proteins. Recent advances in high-throughput screening methods, together with a better understanding of the interaction of existing drugs with this target, have created new prospects for discovering novel haem-targeting chemotypes and for target-based structural design of new drugs. Finally, the discovery that Schistosoma mansoni also produces haemozoin suggests that new drugs of this type may be chemotherapeutic not only for malaria, but also for schistosomiasis. These recent developments in the literature are reviewed.
Community-based care of stroke patients in a rural African setting
S Wasserman, Linda de Villiers, A Bryer
South African Medical Journal , 2009,
Abstract: Background. To develop a community-based model of stroke care, we assessed discharge planning of stroke patients, available resources and continuity of care between hospital and community in a remote rural setting in South Africa. We sought to determine outcomes, family participation and support needs, and implementation of secondary prevention strategies. Methods. Thirty consecutive stroke patients from the local hospital were assessed clinically (including Barthel index and modified Rankin scores) at time of discharge and re-assessed 3 months after discharge in their homes by a trained field worker using a structured questionnaire. Results. Two-thirds of all families received no stroke education before discharge. At discharge, 27 (90%) were either bed- or chair-bound. All patients were discharged into family care as there was no stroke rehabilitation facility available to the community. Of the 30 patients recruited, 20 (66.7%) were alive at 3 months, 9 (30%) had died, and 1 was lost to follow-up. At 3 months, 55% of the remaining cohort were independently mobile compared with 10% at discharge. Of the 20 surviving patients, 13 (65%) were visited by home-based carers. Only 45% reported taking aspirin at 3 months. Conclusions. The 3-month mortality rate was high. Most survivors improved functionally but were left with significant disability. Measures to improve family education and the level of home-based care can be introduced in a model of stroke care attempting to reduce carer strain and reduce the degree of functional disability in rural stroke patients.
Stress and its implications for family practice
J J Spangengberg, A de Villiers
South African Family Practice , 2007,
Abstract: An underlying component of stress that manifests in physical symptoms is present in a high percentage of patients visiting the family practitioner, who is expected to help them cope with stress. In this article the transactional model of stress is briefly explained. Guidelines are given for assessing the role of stress in physical symptoms and for consulting with stressed patients. Subsequently, some stress moderators are discussed and guidelines are given for implementing these in practice. Lastly, primary, secondary and tertiary stress interventions in primary health care are briefly discussed. South African Family Practice Vol. 49 (6) 2007: pp. 30-32

Protecting Minorities on a Non-Territorial Basis—Recent International Developments  [PDF]
Bertus de Villiers
Beijing Law Review (BLR) , 2012, DOI: 10.4236/blr.2012.34023
Abstract: The protection of minorities by way of non-territorial arrangements, also called cultural autonomy, is receiving increased attention in theory and practice. While federalism and decentralisation often afford indirect protection of minorities on a territorial basis—be it by way of autonomy to state or local governments—Dispersed minorities often fall through the territorial “cracks”. Cultural autonomy can potentially play a vital role to grant protection to minorities that do not have a territorial base of their own. This article, which reflects on recent international developments to protect minorities by way of non-territorial arrangements, shows how the theory and practice of cultural autonomy have gained legitimacy in countries such as Estonia, Slovenia, Kosovo and Finland. Finally, potential lessons are identified for potential application in other emerging democracies.
Stroke outcomes in a socio-economically disadvantaged urban community
L de Villiers, M Badri, M Ferreira, A Bryer
South African Medical Journal , 2011,
Abstract: Aims. To determine survival, disability and functional outcomes of stroke patients following their discharge from an acute stroke unit in an urban community with limited rehabilitative resources. Methods. Stroke patients were recruited from a district hospital in Cape Town and followed-up for 6 months. Clinical characteristics, demographic and socioeconomic data, and disability and function as measured by modified Rankin Score (mRS), modified Barthel Index (mBI) at recruitment and 3 follow-up visits, were recorded. Results. The study included 196 patients. Median age was 60 (IQR 51 - 69) years, 135 (68.9%) were female, 57.7% black, 42.3% coloured, and 45 (23%) died within 6 months. At discharge, median mBI score was 7 (IQR 3 - 12) and median mRS 4 (IQR 3 - 5). In the multivariate regression models, only function (mBI OR 0.88, 95% confidence interval (CI) 0.79 - 0.96, p<0.0001) and disability (mRS 0R 2.34, 95%CI 1.20 - 4.54, p<0.0001) were independently associated with risk of death. Shack housing was independently associated with moderate or severe disability (odds ratio 3.42, 95%CI 1.22 - 9.59, p=0.02). Despite limited rehabilitation resources, 67% of survivors had mild to moderate disability at 6 months. Conclusion. Apart from initial stroke severity, risk factors for poor survival were a severe disability category and the presence of impaired swallowing at discharge. Shack housing was independently associated with poor functional outcomes. These findings should be helpful in allocating home-based care and inpatient rehabilitation resources to high-risk groups to improve outcomes.
Sand moisture as a factor determining depth of burrowing in the oniscid isopod Tylos granulatus Krauss
C.J. de Villiers,A.C. Brown
African Zoology , 2012,
Abstract: ENGLISH ABSTRACT: Tylos granulatus, a sandy-beach isopod, prefers an environmental moisture range exceeding 3,4% but less than 13%. The depths to which the animals burrow are, at least partly, determined by the moisture gradient in the sand. They are, however, incapable of burrowing into totally dry sand. Animals alter their position in the sand in response to changes in moisture content so as to ensure exposure to suitable conditions. ********** AFRIKAANSE OPSOMMING: Tylos granulatus, 'n sandstrand isopod, verkies 'n omgewingsvogtigheidsgraad wat 3,4% oorskry maar minder is as 13%. Die dieptes waartoe die diere grawe word, minstens gedeeltelik, deur die vogtigheidsgradient in die sand bepaal. Hulle is egter nie in staat om in 'n heeltemal dro sand te grawe nie. Die organismes kan hulle posisie in die sand verander met 'n verandering in vogtigheid, om so, blootstelling aan geskikte toestande te verseker.
