The ‘U-turn’: Business confi dence in a Karoo town
D van Rooyen
Southern African Business Review , 2011,
Abstract: Business confidence helps explain the sentiments that business owners or managers have towards current and future business conditions. This article compares several ways of measuring business confi dence. Business confi dence is mostly surveyed at the level of the nation-state rather than at the level of municipalities or towns. This article provides a methodology for business-confi dence surveys at the local level. This approach has been piloted in the town of Beaufort West in the Karoo area of South Africa. There are plans for a new uranium mine near Beaufort West, and the researchers speculate on its impact on the broader local business confi dence.
An aspect of language for academic purposes in secondary education: complex sentence comprehension by learners in an integrated Gauteng school
D van Rooyen, H Jordaan
South African Journal of Education , 2009,
Abstract: Language for academic purposes is an important concept, not always recognised and developed within the education system. The ability to use language for learning can be diff icult for individuals who are educated in a second language. They are required to master complex concepts in a language they are still acquiring. We aimed to discover how secondary school learners performed on an aspect of academic language: complex sentence comprehension. A group of 464 adolescent participants’ performance on the grammatical understanding subtest of the Test of Adolescent Language was analysed in relation to their status as first or second language English learners, their grade, gender, literacy experiences, preferred modality of learning, and other factors deemed to influence language acquisition in modern society. The results indicated that the majority of learners achieved within the average range. There were significant differences between the male and female participants and the junior phase ESL males achieved the lowest scores. It was concluded that it may take 8–9 years of formal schooling for some individuals to acquire the requisite academic language proficiency, particularly if they are learning in their second language. This has important implications for the teaching and assessment of second language learners.
Endotracheal tube cuff pressure management in adult critical care units
P Jordan, D van Rooyen, D Venter
Southern African Journal of Critical Care , 2012,
Abstract: Background. The monitoring of endotracheal tube (ETT) cuff pressure in intubated patients is important in preventing complications related to cuff over- and under-inflation. Objectives. To explore and describe the existing practice related to ETT cuff pressure management by professional nurses in adult critical care units (CCUs) in the public and private healthcare sectors. Method. A quantitative survey was used. Data were collected from professional nurses from adult CCUs in the public and private healthcare sectors in the Nelson Mandela Metropole, Eastern Cape, South Africa, using a structured self-administered questionnaire based on a literature review. Results. The survey response was 75% (100/134). Practice variances included the frequency of cuff pressure monitoring: only 52% of respondents performed cuff pressure measurements every 6 - 12 hours; 32% reported performing measurements at 2 - 4-hourly intervals; 15% only assessed cuff pressure when a leak occurred; and 1% never monitored cuff pressure. Of the 100 respondents, 37% used the cuff pressure measurement (CPM) method, 24% used the palpation method or listened to air leaks, and 22% used minimal occlusive volume (MOV). None of the respondents used the minimal leak technique (MLT). Only 20% of the respondents maintained cuff pressures at 18 - 22 mmHg. Thirty-one per cent indicated that they still performed the practice of cuff deflation and re-inflation before and after suctioning. There were incongruities related to the management of air leaks and the amount of air instilled. Conclusion. Practice variances were noted among the professional nurses, especially in the private healthcare sector. The lack of evidence-based clinical decision-making related to cuff pressure management in mechanically ventilated patients was evident. Best practice recommendations need to be used effectively when performing ETT cuff pressure management, to reduce practice variance, standardise safe patient care, and minimise complications.
The experiences of AIDS orphans living in a township
D van Rooyen, S Frood, E Ricks
Health SA Gesondheid , 2012,
Abstract: An overwhelming challenge to health-care professionals today, is the rendering of care services to AIDS orphans. This article is based on a study that explored and described the lived experiences of AIDS orphans in a township in order to understand their ‘life world’ as AIDS orphans. A further purpose was to provide information to primary health-care nurses (PHCNs), related professionals and partners involved in the care of these children, so that they could plan a care response to meet the orphans’ unique needs. A qualitative research design that used an explorative, descriptive, contextual and phenomenological strategy of inquiry was employed. Data were collected by means of in-depth interviews from a purposively selected sample, and were analysed according to the steps of qualitative data analysis proposed by Tesch (Creswell 1994). Guba’s model was used to ensure the trustworthiness of the qualitative data. Two main themes and their sub-themes were identified. The first theme was that children experience devastating changes in their life circumstances when they become AIDS orphans. The second theme highlighted how the participants rediscovered hope to persevere. Recommendations directed at nursing practice, education and research, were made based upon the findings.
A model for higher education campus health services
EJ Ricks, J Strümpher, D van Rooyen
Health SA Gesondheid , 2010,
Abstract: This study was undertaken in order to develop a holistic healthcare model that would assist registered nurses who are employed at a higher education campus’ health service to render a healthcare service relevant to the healthcare needs of the campus healthcare consumers. A theory-generative, qualitative, explorative,descriptive and contextual research design for theory generation was used to develop a holistic healthcare model for a higher education campus’ health service. It became evident throughout the study that the participants experienced a need for a more comprehensive healthcare service on campus. The main concepts of holistic healthcare were identified from the information obtained from the in-depth, focus group interviews that were conducted with the participants. The process of theoretical model generation was conducted according to the steps of theory generation as proposed by Walker and Avant (1995:39), namely that of concept analysis,the placing of concepts in relationships, a description of the model and guidelines to operationalise the model. This model provides a structured holistic healthcare frame of reference for registered nurses employed in a campus health service at a Higher Education Institution (HEI) and could be used to assist all campus healthcare consumers to become balanced whole persons who are able to realise their dreams and maintain consistency with regard to optimal health and capacity. Opsomming Hierdie studie is onderneem om teneinde ‘n holistiese gesondheidsorgmodel te ontwikkel wat geregistreerde verpleegkundiges, werksaam by ‘n ho r onderwys kampusgesondheidsorgdiens,kan help om ‘n gesondheidsorgdiens te kan lewer wat relevant is tot die gesondheidsbehoeftes vandie kampusgesondheidsorg verbruikers. ‘n Teorie-generende, kwalitatiewe,eksplorerende, beskrywende en kontekstuele navorsingsontwerp vir teorie genering is gebruik om ‘n holistiese gesondheidsorgmodel vir ho r onderwys kampusgesondheidsorgdienste te ontwikkel. Tydens die studie het dit duidelik geword dat die deelnemers ‘n behoefte het daaraan om ‘n meer omvattende gesondheidsorgdiens op kampus te ervaar. Die hoof konsepte van holistiese gesondheidsorg was ge dentifiseer vanuit die data wat verkry was deur die in-diepte fokusgroep onderhoude wat met die deelnemers gevoer is. Die proses van model-generering is uitgevoer volgens die stappe soos voorgestel deur Walker en Avant(1995:30) naamlik dit van konsep-analise, die plasing van konsepte in verhoudings, die beskrywing van die model en die riglyne om die model operatief te maak. Die model maak voorsiening vir ‘n gestruktureerde holistiese gesondheidsorgraamwerk wat as verwysing kan dien vir geregistreerde verpleegkundiges werksaam by ‘n kampus gesondheidsorgdiens by ‘n Ho r Onderwys Instansie(HOI) en kan gebruik word om alle kampus gesondheidsorgverbruikers te help om gebalanseerde, heel persone te word wat in staat is om hul drome te vervul en konsekwentheid met betrekking tot optimale gesondheid en
Nursing in Saudi Arabia: Reflections on the experiences of South African nurses
D van Rooyen, CD Telford-Smith, J Strümpher
Health SA Gesondheid , 2010,
Abstract: The purpose of the study was to describe and reflect on the lived experiences of the South African nurses residing and working in the Kingdom of Saudi Arabia. A qualitative, exploratory, descriptive and contextual design with a phenomenological approach was adopted. Data were collected by means of individual interviews and the personal journals of the nurses who met the sampling criteria. The data analysis was done according to Tesch’s descriptive method (in Creswell 1994). The main theme that emerged was one of ‘cultural diversity’. Sub-themes related to the nurses’ religious/spiritual, environmental, emotional/psychological and professional experiences were also identified. A literature control was undertaken to verify the results. Limitations were highlighted, conclusions were drawn and recommendations relating to nursing research, education and practice were made.
A preliminary report on the dynamics of the vegetation of the Kalahari Gemsbok National Park
N van Rooyen,D. J van Rensburg,G. K Theron,J Du P Bothma
Koedoe : African Protected Area Conservation and Science , 1984, DOI: 10.4102/koedoe.v27i1.570
Abstract: Different methods were used intermittently to monitor the changes in the floristic composition, basal cover and density of the herbaceous and woody vegetation over a seven year period in the Kalahari Gemsbok National Park. Periods of drought and the variability of rainfall appear to have a significant influence in the short term on herbaceous species, while there was not much variation in the woody species composition or density.

N. Van Rooyen,D.J. van Rensburg,G.K. Theron,J. du P. Bothma
Koedoe : African Protected Area Conservation and Science , 1988, DOI: 10.4102/koedoe.v31i1.490
Abstract: A check list containing 397 plant species has been compiled for the Kalahari Gemsbok National Park which occupies an area of approximately 9 600 km2. These species represent 191 genera and 51 families. The Monocotyledonae are represented by 98 species (24,7 of the total number of species) and the Dicotyledonae by 299 species (75,3 of the total number of species). According to the life form spectrum the Kalahari Gemsbok National Park is a therophyte-hemicryptophyte area.
Medical student participation in community-based experiential learning: reflections from first exposure to making the diagnosis
D Cameron, L Wolvaardt, M Van Rooyen, J Hugo, J Blitz, A-M Bergh
South African Family Practice , 2011,
Abstract: Background: Fifth-year medical students from the University of Pretoria participated in a four-week rotation in the primary care clinics of a large metropolitan centre. An academic service-learning (ASL) approach was introduced into this rotation to improve the integration of theoretical learning and clinical practice through relevant community service and structured reflection. Methods: Students wrote semi-structured reflective journals as a means to gaining greater insight into their learning experiences. These reflections were analysed qualitatively with a view to improving the community-based curriculum. Results: Four major themes were identified: expectations and the reality of primary care; service and learning; becoming a doctor; and making a difference. Conclusion: While students gained a deeper insight into their development as clinicians, using an ASL approach also assisted the faculty in making an informed educational diagnosis of the curriculum.
Monitoring of the vegetation around artificial watering points (windmills) in the Kalahari Gemsbok National Park
N. Van Rooyen,D. Bezuidenhout,G.K. Theron,J. du P. Bothma
Koedoe : African Protected Area Conservation and Science , 1990, DOI: 10.4102/koedoe.v33i1.453
Abstract: Vegetation changes around artificial watering points were monitored in the Kalahari Gemsbok National Park from 1978 to 1989. Both rainfall and grazing influenced the vegetation but rainfall appeared to be the more significant factor. The above-average rainfall during the years preceding 1978 contributed to a relatively high basal cover in 1978. Since 1978, however, below-average rainfall was recorded resulting in a decline in basal cover, presence, frequency and density of most of the plant species. It seems likely that a wet cycle commenced in 1988, which is reflected in higher rainfall and an increase in basal cover, presence, and density. Some species maintained a relatively constant presence, some increased, and some declined during the study period. The monitoring is being continued.
