Breastfeeding: Mothers and health practitioners in the context of private medical care in Gauteng
D du Plessis
Health SA Gesondheid , 2009,
Abstract: Despite the well-documented health benefi ts of breastfeeding and recommendations by the Department of Health for women to exclusively breastfeed for approximately the fi rst six months of life and continuation beyond one year, a large percentage of South African women do not breastfeed their infants, or only do so for a short period of time. No national South African statistics are available but fi gures emerging from the attendance of mothers at a baby clinic on the West Rand in Gauteng indicated the following: 64% of the mothers breastfeed up to six weeks, after which the fi gure rapidly declines to less than 20% at three months (Truter 2007). Several studies have assessed the attitudes of health care personnel towards breastfeeding, but little is known of the type of information given to breastfeeding mothers by private medical practitioners who are the frontline of contact with clients and who may convey information that either promotes or discourages breastfeeding. The following question was thus formulated: With regard to breastfeeding, what are the constraints to breastfeeding in private practice? Therefore, in order to understand the constraints to breastfeeding, the purpose of this study was to assess the breastfeeding information given to pregnant women by health professionals in private practice. The specifi c objectives of the study were to determine the breastfeeding recommendations made by private health professionals during pregnancy, to describe the management of breastfeeding in the consulting rooms of private medical practitioners, and to describe women’s experiences of breastfeeding in private hospitals. In Phase 1 of the study the population comprised all mothers who attended a support group for new mothers at a private post-natal clinic In Phase 2 the population comprised all mothers who attended a community baby clinic or support group. The sample consisted of all primigravidae who breastfed or attempted to breastfeed in the fi rst six weeks. Purposive convenient sampling, as described by Babbie and Mouton (2002:166), was used in both phases of the study. All participants chose a gynaecologist as the primary care giver and delivered in various private hospitals in Johannesburg. Data were collected by means of an anonymous questionnaire, compiled from national and international literature, as well as personal interviews. Data from the questionnaires were analysed by hand. Descriptive statistics were applied. The interviews were analysed according to the descriptive analysis suggested by Tesch (in Creswell, 1994:155). Themes that emerged were clustered and coded. A co-coder, experienced in the field of qualitative research, assisted with the analysis of the transcripts of the interviews. A literature control was conducted to validate the fi ndings. Ethical considerations were based on the DENOSA Ethical Standards for Nurse Researchers (1998:2.3.2–2.3.4). Themes and sub-themes were identifi ed.

Terminologiebestuur in Suid- Afrika: 'n Ideaalmodel *
D Ferreira, T du Plessis
Lexikos , 2010,
Abstract: Die nuwe taalbestel in Suid-Afrika het tot gevolg gehad dat die ontwikkeling, die uitbouing, die bestuur en ook die verspreiding van terminologiese inligting in elf amptelike tale gedoen moet word. 'n Veranderde terminologiebestuursprogram moet derhalwe daargestel word om aan die behoeftes van 'n nuwe terminologiegemeenskap te voldoen. So 'n model sou ideaal gesien binne die Nasionale Taaldiens se terminologieko rdineringsafdeling ge mplementeer kon word. In die eerste gedeelte van hierdie artikel word 'n model voorgestel van hoe terminologiebestuur suksesvol binne 'n terminologiebestuursentrum aangepak kan word. In die tweede gedeelte van die artikel word die implikasies van die model in die Suid-Afrikaanse situasie verreken om vas te stel hoe die terminologiebestuursprogram aangepas sou kon word om aan die eise van die nuwe taalbestel te voldoen en om die nuwe teikengroep(e) voldoende te bereik. Sleutelwoorde: Amptelike Tale, Beplanning En Ko rdinering, Disseminering, Evaluering, Gemarginaliseerde Tale, Inheemse Tale, Implementering, Meertalige Terminologiebestuursisteem, Navorsing, Ontwikkelende Tale, Ontwikkelde Tale, Opleiding, Standaardisering, Termbank, Terminologie, Terminologiebestuursentrum, Terminologiebestuursprogram, Terminologieontwikkeling, Terminologiewerk
Terminologiebestuur in Suid-Afrika. 'n Beoordeling van drie werkmetodes*
D Ferreira, T du Plessis
Lexikos , 2007,
Abstract: Die verampteliking van elf tale in Suid-Afrika het tot gevolg dat daar 'n steeds groter wordende behoefte aan die ontwikkeling, die uitbouing en die bestuur van terminologie asook die verspreiding van terminologiese inligting in al hierdie tale bestaan. Hierdie artikel beoordeel drie terminologiese werkmetodes wat tans suksesvol gebruik word by terminologiebe-planning, terminologieko rdinering en terminologiebestuur. Deur die navorsing is daar vasgestel dat terminologiebestuur in verskillende omgewings verskillend aangepak word, deur verskillende persone geadministreer word en verskillende pro-dukte tot gevolg het. Die doelwitte met die versameling en disseminering van terminologie het dus 'n baie belangrike invloed op die werkmetode wat by terminologiebestuur binne 'n spesifieke omgewing gebruik word. Die drie werkmetodes staan bekend as die linguisties geori nteerde werkmetode, die verta-lingsgeori nteerde werkmetode en die taalbeplanningsgeori nteerde werkmetode. Die implikasies van die verskillende werkmetodes word binne die Suid-Afrikaanse situasie ondersoek om te bepaal watter een tans die beste opsie vir terminologieontwikkeling en terminologiebestuur in Suid-Afrika bied. Sleutelwoorde: amptelike tale, brontaal, doeltaal, gemarginaliseerde tale, inheemse tale, linguisties geori nteerde werkmetode, meertalige kommunikasie, ontwikkelde tale, ontwikkelende tale, taalbeplanning, taalbeplanningsgeori nteerde werkmetode, taalontwikkeling, termino-logie, terminologiebestuur, terminologieontwikkeling, terminologiewerk, vertalingsgeori nteerde werkmetode, wêreldtaal

Sexual Harassment in the Education Sector
D Smit, V du Plessis
Potchefstroom Electronic Law Journal/Potchefstroomse Elektroniese Regsblad , 2011,
Abstract: Education should safely shape the minds and attitudes of young adults and children, especially with the in loco parentis principle in mind. Young adults who have experienced sexual harassment in the very environment that should have protected them as learners suffer greatly from social problems and from emotional and academic strain. Victims often become future harassers themselves. Sexual harassment should be eradicated from the education sector in toto to ensure a safe learning environment. High incidences of harassment have been found among college students in America, while a very small percentage of such transgressions have been reported. Similar statistics in South African universities are not available, the problem is therefore managed in a void. The position in schools is more alarming. In South Africa it has been found that 30 per cent of girls are raped at school and that male learners and educators are the main culprits. Not only is the magnitude of this problem gravely underestimated, but the effect of sexual harassment on learners has also not been managed properly. The authors argue that the focus is on avoiding legal responsibility and accountability, rather than on being proactive. The historic invisibility of sexual harassment in education can be attributed to the wrongful silencing thereof. KEYWORDS: Sexual harassment; schools; workplace rights; educational rights
Calvin in word and deed: A communicological appreciation
D.F. du Plessis
Koers : Bulletin for Christian Scholarship , 2001, DOI: 10.4102/koers.v66i1&2.390
Abstract: John Calvin’s views on the role of the preacher, as well as the manner in which he applied these views in practice, are examined by using a simplified linear model of communication. Firstly, Calvin’s view on the role of the preacher is examined – as expressed in the Institutes, his letters and commentaries. From a communication perspective, it is clear that, from what Calvin said, he thoroughly saw himself as a servant, relying on the Word of God – a servant who had to execute his assignment in obedience to what God (communicator in the model) expected from him as an instrument in His hands. Secondly, in addition to Calvin’s views on his role as a preacher, it was also established how he acted in some demanding situations. The consistency of his thinking was illustrated by comparing what he did to what he said. The examination revealed that Calvin’s action was to bring the Word. Calvin’s actions were therefore consistent with the views articulated in his writings. Thirdly, from his letters to persecuted followers, we can deduce Calvin’s views on the practical application of the ideas which he stated in the Institutes and other publications. The article concludes that, if measured against the simplified linear communication model, it can be assumed that Calvin saw himself as a communication medium or channel used by God to convey His message and not as a communicator following his own agenda.

Cysteine-free peptides in scorpion venom: geographical distribution, structure-function relationship and mode of action
D Elgar, J Du Plessis, L Du Plessis
African Journal of Biotechnology , 2006,
Abstract: Scorpion venoms are well known sources of Na+-channel, K+-channel, Cl--channel, Ca2+-channel and ryanodine channel selective peptides. In 1993, the first cysteine-free peptide was isolated from scorpion venom. Within the last six years, cysteine-free peptides with and without antimicrobial activity have been isolated from scorpion venom. The first antimicrobial peptides being parabutoporin and hadrurin, after which nine more have followed. Characteristics of these peptides include pore-formation and/or antimicrobial activity. Six peptides of similar structures without antimicrobial activity have also been isolated. Two of these peptides have bradykinin-potentiating functions. The functions of the other four are unknown. These peptides have the potential to combat cancer, a variety of skin or wound bacterial and fungal infections. This review will focus on the primary and secondary structures as well as reported functions and applications of the cysteine-free peptides identified in scorpion venom.
Multivariate differential analyses of adolescents’ experiences of aggression in families
C Myburgh, M Poggenpoel, D Du Plessis
South African Journal of Education , 2011,
Abstract: Aggression is part of South African society and has implications for the mental health of persons living in South Africa. If parents are aggressive adolescents are also likely to be aggressive and that will impact negatively on their mental health. In this article the nature and extent of adolescents’ experiences of aggression and aggressive behaviour in the family are investigated. A deductive explorative quantitative approach was followed. Aggression is reasoned to be dependent on aspects such as self-concept, moral reasoning, communication, frustration tolerance and family relationships. To analyse the data from questionnaires of 101 families (95 adolescents, 95 mothers and 91 fathers) Cronbach Alpha, various consecutive first and second order factor analyses, correlations, multiple regression, MANOVA, ANOVA and Scheffè/ Dunnett tests were used. It was found that aggression correlated negatively with the independent variables; and the correlations between adolescents and their parents were significant. Regression analyses indicated that different predictors predicted aggression. Furthermore, differences between adolescents and their parents indicated that the experienced levels of aggression between adolescents and their parents were small. Implications for education are given.
