Die staat en die semi-staatsinstellinge 'n vraagstuk van vryheid en beheer*
Die onderw erp wat vir bespreking by hierdie geleentheid gekies is, staan in verband m et die sake van ons eie tyd en ons eie land. Ons eie tydsom standighede kom ter sprake deurdat die verskynsel van die sem i-staatsinstellinge kenm erkend van die tw intigste eeu is. Dit het naam lik betrekking op die huidige staatstaak, en dien as voorbeeld van die aanpassing en uit- bouing van die staat se organisasie om diĂ© taak te kan uit- voer. Gesien die belangrike rol wat die staat tans speel, be- hoort die soeklig op sy werksaam hede en organisasie na my mening by te dra tot ân beter begrip van die tyd en die wĂȘreld waarin ons lewe
Developing a Learner's Corpus: the case of a First-Year Module in Mathematics
A learner's corpus is a body of writing for use by a student whose first language is not (in this case) English to improve his/her use of (in this case) academic scientific terminology. In this case study, a learner's corpus was developed for a first-year mathematics module for students in the biological sciences. Lecturers struggle with big classes and a fairly high failure rate which they have addressed in a variety of ways. The learner's corpus is one of an array of support mechanisms built into the teaching-learning process and aims to support the development of academic literacy in this module in particular. In the process of developing and refining this learner's corpus it was compared to Coxhead's Academic Word List to determine whether a gen-eral academic word list may not include enough terms to render tailor-made learner's corpora unnecessary. The study concludes that the most frequent terms used in this module either do not appear in the Academic Word List or have such a specialised meaning that general academic sup-port on the basis of the word list would probably not be very useful for students.

Every teacher a language teacher? Developing awareness of multingualism in teacher education
Given the multilingual nature of South African communities, schools are usually linguistically diverse. These contexts create a challenging environment for teaching effectiveness given the fact that learners are required to use high status languages for academic purposes. It is therefore important that teacher education programmes recognise and respond effectively to this challenge. We argue that the demand for every teacher to be a language teacher is a useful way of framing how we view teaching in multilingual environments. We report on a course called Multilingual Education, a module on a Post-graduate Certificate in Education at Stellenbosch University. In the article the focus is on materials design as one important aspect of bilingual practice as well as evidence of increased language awareness. We discuss student perceptions of the course in the form of qualitative data collected by the lecturers responsible for the module and quantitative data in the shape of formal student feedback collected by the university. We conclude by highlighting the value of such courses as well as the awareness of multilingualism that it raised with students who were preparing to teach in these linguistically diverse contexts.Keywords: Bi/Multilingualism, teacher education, bi/multilingual language awareness, bi/multilingual materials desig
Rasberry Pi and BeagleBones : evaluating a cost effective GPS system for onâmine navigation
Abstract: The South African Mine Health and Safety Act (MHSA) requires the mine surveyor to inform the manager of all workings within 100 metres of other workings, abandoned areas and hazardous accumulations of water or gas. The main purpose of this requirement is to ensure that all employees are aware and can take all the necessary precautions against unâplanned breakthroughs, falls of ground and subsidence. In the case where mines are mining through abandoned workings in order to remove remnant pillars and previously unmined reserves, the potential for subsidence and equipment falling into excavated areas become a reality. A single incident where a machine falls into a collapsed working can amount to in excess of R1 million per incident, excluding the risk of loss of life or serious injury. An unplanned collapse of workings in the specific case study can also lead to sufficient air flow into the old underground to cause spontaneous combustion of the remaining pillars. Although systems for navigation of drill rigs exist the cost to deploy a similar unit to all vehicles in the mining area is prohibitive. A lowâcost system that can navigate a vehicle and indicate to the operator what the subsurface features look like in the direct surroundings of the vehicle was developed using offâtheâshelf technologies. This paper discusses the process of developing a lowcost navigation system towards a real time information management system for a mining operation. Benefits from this system may be applied in underground navigation and guiding rescue services in the search of illegal miners in abandoned mines
Knowledge sharing via enterprise intranets â asking the right questions.
The corporate intranet is a common feature of both public and private sector enterprises today. It has been found that once the infrastructure and architecture are in place, the real challenge for enterprises is to get users to contribute their own knowledge willingly and to use that of others. The culture of the enterprise needs to promote it. To stay competitive, enterprises need relevant and current knowledge from a variety of sources to allow them to innovate and create new knowledge and consequently new products or solutions for their clients. The enterprise intranet could be the ideal tool to make this possible. For effective knowledge sharing to take place, a knowledge sharing culture and proper knowledge sharing tools and facilities are required
Successful first-year learning: A social cognitive view of academic literacy
The research data used in this article are drawn from a study conducted in a business faculty at a Historically Black South African University during 2009 and 2010. A comparison was made in the study between two groups of first-year students: a group that had passed all their modules and a group that had failed some of their modules at the end of their first year of study. The aim was to investigate factors that had an impact on the successful completion of the first year of study by problematising theperception that those students from disadvantaged backgrounds or under-resourced schools are necessarily disadvantaged and destined to fail. In this article the focus is on the successful group of students and their mastery of academic discourse situated in the complexity of social and academic interaction. The findings indicate that the inter-relatedness of personal, academic, social and institutional factors mirror the inter-related way in which the students had experienced them. These findings furtherunderline the fact that successful learning is a complex and multi-layered process that is ongoing and that needs to be monitored, sustained and evaluated throughout studentsâ study careers. The studentsâ personal perspectives on academic study provided not only evidence that the development of academic literacy is socially situated and constructed but also showed how successful students manage their academic learningto mitigate under-preparedness and adverse personal circumstances.Key words: Students, successful learning, academic literacy, interrelated, socially situated
Ashotgun marriage community health workers and government health services
In 1988 the Western Cape Regional Services Council (RSC) initiated a community health worker (CHW) project in Khayelitsha in order to extend its preventive services to people in the community and promote 'community upliftment'. An evaluation of this project was undertaken in 1991 and 1992 in order to examine the potential of this local health authority-run CHW project to be an appropriate primary health care model. Qualitative research methods were used to explore the nature of the work done by the CHWs, whether they were accepted in their communities, and whether the project functioned as part of an integrated health service infrastructure in Khayelitsha. The CHWs were found to provide the basis for a potentially effective, community-responsive service. However, several structural problems mitigated against this service. Relations between the CHWs and nurses in all the formal public health services in the area were superficial and fraught with problems. There were significant differences and conflicting policies between the RSC's CHW project and other neighbouring nongovernment CHW projects, and these posed various threats to both the RSC and the non-government projects. One of the most serious of these differences was that the RSC project had no structures or plans for community involvement in the running of the project. Before a CHW project is initiated, several critical issues need to be carefully considered and discussed with all the relevant stakeholders. Furthermore, CHWs need to be flexible, and accountable to the communities in which they work. Before employing CHWs, formal public health authorities need to consider carefully whether they are able to meet these criteria
On the pumping of the CS() masers in W51 e2e
We present the results of numerically solving the rate equations for the
first 31 rotational states of CS in the ground vibrational state to determine
the conditions under which the J=1-0, J=2-1 and J=3-2 transitions are inverted
to produce maser emission. The essence of our results is that the CS()
masers are collisionally pumped and that, depending on the spectral energy
distribution, dust emission can suppress the masers. Apart from the J=1-0 and
J=2-1 masers the calculations also show that the J=3-2 transition can be
inverted to produce maser emission. It is found that beaming is necessary to
explain the observed brightness temperatures of the recently discovered CS
masers in W51 e2e. The model calculations suggest that a CS abundance of a few
times and CS() column densities of the order
are required for these masers. The rarity of the CS
masers in high mass star forming regions might be the result of a required high
CS abundance as well as due to attenuation of the maser emission inside as well
as outside of the hot core.Comment: 13 pages, 15 figure
A generational perspective on work values in a South African sample
Published ArticleConsiderable interest has been generated globally by researchers regarding the impact of
generational differences on employee interaction in the workplace. This is due to the assertion
that multicultural environments combined with multigenerational workforces create additional
organisational stumbling blocks for global leadership (Roongrerngsuke & Liefooghe, 2013). As
such, it is hypothesised that intergenerational conflict in the workplace occurs as a result of
differences in terms of values, cognitions and behaviour, with negative consequences for
communication, teamwork and ultimately organisational outcomes (Sessa, Kabacoff, Deal &
Brown, 2007). Furthermore, a new generation of employees is entering the workplace, with
different values and preferences towards work, which influences human resource processes
(Latkovikj & Popovska, 2015). Elaborating on the work of DâAmato and Herzfeldt (2008), it is
indicated that work motivation and retention concerns are related to generational differences
(Seipert & Baghurst, 2014)
