Derrida's 'The Purveyor of Truth' and constitutional reading

De Ville, Jacques (Springer, 2008)

[more]

[less]

Abstract:

In this article the author explores Jacques Derrida’s reading in ‘The Purveyor of Truth’ of Edgar Allan Poe’s ‘The Purloined Letter’. In his essay, Derrida proposes a reading which differs markedly from the interpretation proposed by Lacan in his Seminar on ‘The Purloined Letter’. To appreciate Derrida’s reading, which is not hermeneutic-semantic in nature like that of Lacan, it is necessary to look at the relation of Derrida’s essay to his other texts on psychoanalysis, more specifically insofar as the Freudian death drive is concerned. The present article explores this ‘notion’ as elaborated on by Freud in Beyond the Pleasure Principle as well as Derrida’s reading of this text. It also investigates the importance of the ‘notion’ of the death drive as well as the significance of Derrida’s reading of The Purloined Letter for constitutional interpretation.

Derrida, the conditional and the unconditional

De Ville, Jacques (Juta Law, 2007)

[more]

[less]

Abstract:

In his recent book, Law and Sacrifice: Towards a Post-Apartheid Theory of Law, Johan van der Walt gives a clear exposition of the possible impact of inter alia Jacques Derrida's thinking on law. In this article, the book is critically analyzed and it is shown that Derrida's texts provide scope for a different interpretation. With reference to a number of themes it is shown that Derrida's thinking is more far reaching than in Van der Walt's model. The unconditional for example plays a vital role in Derrida's thinking while it is almost absent in Van der Walt's model. Van der Walt stresses the need for plurality and the impossibility of reconciliation between different views of the law in a particular case. Such an approach can have conservative political consequences. A different interpretation of Derrida, where the unconditional is more prominent, holds more promise for a post-apartheid theory of law.

Desire and language in Derrida’s 'Force of Law'

De Ville, Jacques (Franz Steiner Verlag, 2009)

[more]

[less]

Abstract:

In this article, the author proposes a reading of 'Force of Law' from two angles: boundless desire and the ‘law’ of language. The author contends that an analysis from these perspectives casts new light on the notion of the ‘mystical’, as well as repetition, singularity and good/evil as they appear in Derrida’s text. In exploring the ‘notion’ of desire, the article focuses specifically on Derrida’s analysis of Freud’s Beyond the Pleasure Principle in To Speculate – On Freud where the death drive is explored. The author shows the importance of this essay for an understanding of the relation between justice and law. The mystical and justice, the author contends, is to be understood with reference to the death drive, and repetition or law enforcement as its return. Law enforcement could also be viewed in terms of the ‘notion’ of iterability in Derrida’s texts on language. These perspectives furthermore allow for an understanding of singularity in terms of unconditionality and of justice as beyond good and evil.

The detailed forms of the LMC Cepheid PL and PLC relations

Koen, Chris; Kanbur, S; Ngeow, C (Oxford University Press, 2007)

[more]

[less]

Abstract:

Possible deviations from linearity of the Large Magellanic Cloud Cepheid period–luminosity (PL) and period–luminosity–colour (PLC) relations are investigated. Two data sets are studied, respectively from the Optical Gravitational Lensing Experiment (OGLE) and MACHO projects. A non-parametric test, based on linear regression residuals, suggests that neither PL relation is linear. If colour dependence is allowed for, then the MACHO PL relation is found to deviate more significantly from the linear, while the OGLE PL relation is consistent with linearity. These findings are confirmed by fitting ‘Generalized Additive Models’ (non-parametric regression functions) to the two data sets. Colour dependence is shown to be non-linear in both data sets, distinctly so in the case of the MACHO Cepheids. It is also shown that there is interaction between the period and the colour functions in the MACHO data.

Detection of an increasing orbital period in the subdwarf B eclipsing system NSVS 14256825

Kilkenny, David; Koen, Chris (Oxford University Press, 2012)

[more]

[less]

Abstract:

New timings of eclipses made in 2010 and 2011 are presented for the hot subdwarf B (sdB) eclipsing binary NSVS 14256825. Composed of an sdB star and a much cooler companion, with a period near 0.1104 days, this system is very similar to the prototype sdB eclipsing binary HW Vir. The new observations show that the binary period of NSVS 14256825 is rapidly increasing at a rate of about 12 × 10−12 days orbit−1.

Determinants of obesity in an urban township of South Africa

Puoane, Thandi (MedPharm Publications, 2008)

[more]

[less]

Abstract:

OBJECTIVE: To estimate the prevalence of overweight and obesity, and identify factors associated with Body Mass Index (BMI) and waist circumference (WC) among adults residing in an urban township in South Africa. DESIGN: Cross-sectional study. SETTING: Khayelitsha, a large black township located in Cape Town. SUBJECTS: 107 males and 530 females, aged ≥ 18 years. METHODS: The prevalence of overweight/obesity (BMI ³ 25 kg/m2) and abdominal obesity (WC ≥ 94 cm for men and ≥ 80 cm for women), and their relationship with factors previously found to increase the risk of obesity, such as age, gender, marital status, educational level, employment status, immigrant status from rural to urban, and physical activity level, were assessed using logistic regression analyses. RESULTS: The prevalence of obesity (BMI ³ 30 kg/m2) was 53.4% and 18.7%, and that of abdominal obesity was 71.5% and 23.4%, among women and men respectively. However, more women (21.3%) than men (11.2%) reported walking more than 45 minutes per day. Female gender and being married were associated with a high BMI and large WC. Recent migration was associated with a smaller WC. The level of physical activity was not associated with BMI or WC. CONCLUSIONS: These findings suggest that physical activity may play less of a role in obesity control, or that more than 45 minutes of physical activity per day is required to reduce the risk of obesity, especially in women. At least among South African women, obesity control focused on nutritional interventions may be more beneficial than increasing the intensity or duration of physical activity.

Determining the most appropriate feeding regime for the South African abalone Haliotis midae Linnaeus grown on kelp

Francis, Tamson; Maneveldt, Gavin; Venter, Jonathan (Springer Verlag, 2008)

[more]

[less]

Abstract:

Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not always readily available and farmed abalone are often starved for short periods. The aim of this research was to assess how periodic kelp starvation influences growth of the commercially grown abalone, Haliotis midae Linnaeus. Growth of grow-out abalone was monitored on a commercial abalone farm over a period of six months and consisted of 3 treatments with 2 replicates (n = ±250 abalone per replicate). The treatments were: Control (abalone always given more kelp than what they typically needed); Treatment 1 (abalone fed their weekly ration only once a week); Treatment 2 (abalone fed half their weekly ration every 3 and then 4 days respectively). While the data at first suggest that the control animals outperform the treatment animals, after undergoing an initial adjustment period to the new feeding regime, the treatment animals perform better. Weight gain and feed conversion efficiencies show that the treatment animals perform better overall. The control animals generally required much more feed to produce comparable increases in both length and weight compared to the treatment animals. This study has shown that periodic bouts of starvation is beneficial to Haliotis midae, allowing variable growth spurts when returned to full feed rations.

A developing dialogue – children’s rights, children’s law and economics: surveying experiences from Southern and Eastern African law reform processes

Sloth-Nielsen, Julia (Tilburg University Schoordijk Institute, 2008)

[more]

Abstract:

Law reform in southern and eastern African countries to domesticate the UN Convention on the Rights of the Child (CRC) and the African Charter on the Rights and Welfare of the Child (ACRWC), to synthesize common, civil and customary laws, and to modernise and codify a myriad of outdated statutes affecting children that were inherited from the colonial era has been an ongoing project in numerous states in the region since the first comprehensive Children’s Act, that of Uganda, in 1996. These law reform processes are, in many instances, still ongoing.

Developing locally relevant applications for rural areas: a South African example

Chetty, Marshini; Tucker, William D.; Blake, Edwin H. (SAICSIT, in assocation with ACM, 2004)

[more]

[less]

Abstract:

The digital divide between rural and urban areas within developing countries is vast. We investigate how to address this divide by introducing Information and Communication Technologies (ICTs) into remote rural areas. Our aim is to discover how to create locally relevant software applications with appropriate content for these areas. We use a user centred design approach and a modified software development lifecycle that is participatory, iterative and cyclical. This process is based on principles from Participatory Design and Action Research. This paper presents our initial experience of developing a telemedicine application for a rural village in the Eastern Cape Province of South Africa using this process. We present an overview of the methodology, describe the software application we have developed and cite several challenges we have faced. Finally we conclude that an inter-organisational and inter-disciplinary approach is needed to develop software for remote areas.

Developing reflection and research skills through blogging in an evidence-based practice postgraduate physiotherapy module

Frantz, Jose M.; Rowe, Michael (Health and Medical Publications Group, 2013)

[more]

[less]

Abstract:

Background. Evidence-based practice (EBP) is the process by which a clinician evaluates the quality of evidence before applying it in the management of a patient. Many practitioners struggle to integrate this research-based evidence into their professional practice. Blogs have been identified as useful pedagogical tools that can facilitate the sharing of ideas and clinical experiences among peers to reflect on diverse learning experiences. Objectives. A qualitative research design was used to examine the use of reflective blogging to teach the process of EBP in physiotherapy. Methods. A conveniently selected group of postgraduate students who were registered for an EBP module participated in the study. Blogging was used to teach the process of EBP in physiotherapy using Kolb's cycle as a guiding and an evaluative framework. Students reflected on and shared their learning experiences in ways that exposed the limits of their understanding around certain concepts. Results. The results reflect how students moved from assisted to independent performance by identifying gaps in their own understanding and finding the answers themselves. Conclusion. Reflective blogging was found to be a valuable tool for promoting meaningful learning activities among participants and assisted students in making sense of their shared experiences. It was also an effective tool to be used in teaching the process of EBP.

Abstract:

The title complex, [PdCl2(C20H20N2)] CH3CN, was synthesized by the reaction of 2-[(2,6-diethylphenyl)iminomethyl]quinoline with dichlorido(cycloocta-1,5-diene)palladium(II) in dry CH2Cl2. The PdII ion is coordinated by two N atoms of the bidentate quinoline ligand and by two chloride anions, generating a distorted square-planar coordination geometry around the metal centre. There is a detectable trans influence for the chloride ligands. The crystal packing is characterized by – stacking between the quinoline rings. The use of acetonitrile as the crystallization solvent was essential for obtaining good-quality crystals.

The differences between adolescent users and non-users of addictive substances in a low socio-economic status community: Contextual factors explored from the perspective of subjective wellbeing.

Florence, Maria; Koch, Elize (Psychological Society of South Africa, 2011)

[more]

[less]

Abstract:

This research aimed to explore the differences between adolescents from a low socio-economic Cape Town community who use addictive substances and those who do not, with regard to subjective wellbeing. The Kidscreen52 was used to measure subjective wellbeing in a sample of 179 Grade 10 and 11 learners; 41.3% of the sample was male. Thirty-five percent of the adolescents reported to be substance users, with significantly more males reporting substance use than females in both grades. Scores on four of the sub-scales were significantly different for the substance users and non-users (namely Feelings, General mood, Family and home life, School and learning). A post hoc analysis indicated that males and females differed significantly on General mood, but that this difference did not interact with substance use.
