Abstract: This study explored the incidence, duration and severity of oral mucositis in patients receiving chemotherapy in the Eastern and Western Cape, how this symptom was managed and whether the patients considered the management to be effective. An exploratory, contextual, quantitative survey was conducted. The sampling method was convenience. One hundred and sixty patients were recruited, with 106, (66.3%) participating. Data were collected by means of self-reports, using a self-administered questionnaire. Oral mucositis was a common problem, with 71.7% (n = 76) reporting to have had mucositis. Pain was not effectively managed, as 69.8% (n = 53) of respondents experienced pain whilst only 17.1% (n = 13) reported to have used analgesics. More than half of the respondents used prescribed mouth and throat preparations, whilst 28.9% (n = 22) used non-prescribed self-care measures including potentially harmful products. A significant difference was found between using non-prescribed self-care measures and the duration of oral mucositis (χ2 = 0.81; p = 0.01). The reported grade of mucositis did not influence the use of non-prescribed self-care measures, whilst the more pain patients experienced the less inclined they were to use these measures. The management of oral mucositis remains a challenge. Failure to palliate this distressing symptom can lead to the use of potentially harmful self-care measures. Die studie het die insidensie, tydsduur en intensiteit van orale mukositis in Oos en Wes Kaapse pasi nte wat kankerchemoterapie ontvang verken asook hoe hierdie simptoom hanteer is en die sukses hiervan volgens die pasi nte. ‘n Kwantitatiewe, ekploratiewe, kontekstuele opname is onderneem. ‘n Gerieflikheidsteekproef is gebruik om die deelnemers te verkry. Een hondered en sestig persone is genader en 66.3% (n = 106) het aan die studie deelgeneem. Die datainsamelingsmetode was self-rapportering met behulp van ’n vraelys en beskrywende statistiek is gebruik om die data te verwerk. Orale mukositis was ’n algemene probleem, aangesien 71.7% (n = 76) van die respondente die simptoom ondervind het. Pyn was nie goed beheer nie, aangesien 69.8% (n = 53) pyn ondervind het terwyl slegs 17.1% (n = 13) aangedui het dat hulle analgetika gebruik het. Meer as die helfte van die respondente het voorgeskrewe mond en keel preparate gebruik, terwyl 28.9% (n = 22) self gemedikeer het wat potensi le nadelige preparate ingesluit het. ’n Beduidende verskil is tussen die gebruik van nie voorgeskrewe medikasie en die duur van mukositis bevind (χ2 = 0.81; p = 0.01). Die graad van die mukositi
Natural dyes and dyeing techniques used by craftswomen in the northern Hhohho region of Swaziland

Journal of Family Ecology and Consumer Sciences /Tydskrif vir Gesinsekologie en Verbruikerswetenskappe , 2010,
Abstract: A survey of the plants used by craftswomen in the northern Hhohho region of Swaziland to dye craft materials was conducted. Nineteen plants were identified and details concerning the part of the plant used, the time of year it was harvested and the colour obtained were documented. The techniques used during the dyeing process were also recorded. When an examination of baskets sold at craft markets in Ezulwini could reveal no evidence of the use of natural dyes, an attempt was made to contact the ladies again, but it transpired that the leader of the group had died, and that they discontinued their work with natural dyes. A second group of craft workers was approached. They were shown photographs of the plants used by the first group and recognised eight as dye plants, but were not familiar with the rest of the plants. Both groups used the direct dyeing method, a technique frequently used in southern Africa. Seven of the plants identified were only listed by one other source as a dye plant, but no colours or other details were documented by these authors.

Ecology, water and enterprise development in selected rural South African towns
DF Toerien, MT Seaman
Water SA , 2011,
Abstract: South Africa’s imperatives for rural development and job creation raise the question whether water abundance in a region results in improved enterprise development in rural towns. The enterprise assemblages of 2 groups of towns, a river group from water-abundant areas and a Great Karoo group from the arid heartland of South Africa, were examined using a variety of different methods based on approaches used frequently in ecology. The comparisons included factors such as the ages of towns, clusters of towns and enterprise diversity. Although some hints were obtained that water abundance favoured enterprise development positively, the null hypothesis that water abundance would not influence enterprise development positively could not be rejected. Several lessons were learnt: there are regularities in enterprise development whether in water-abundant or water-scarce areas; these regularities are understandable in terms of recent economic thinking as well as old concepts such as ‘threshold populations’; money is the basic driver of enterprise success and more enterprises in one town than another reflects differences in the amount of money entering and/or circulating in towns; ‘entrepreneurial space’ in certain business sectors is used very effectively by ‘run-of-the-mill entrepreneurs’; towns will give rise to different types of businesses and in proportion to the needs of the customers present in the towns; the degree of utilisation of certain business sectors differs statistically significantly between clusters of towns; and approaches and tools used effectively in the study of ecology offer many advantages for the study of enterprise development dynamics in towns, which are ‘enterprise ecosystems’. The mere presence of abundant water in a region does not automatically translate into enterprise development in towns. Entrepreneurial development should focus on ways and means to increase the flow of money into towns and not merely on its circulation within communities.

Proportionality in enterprise development of South African towns
Danie F. Toerien,Maitland T. Seaman
South African Journal of Science , 2012, DOI: 10.4102/sajs.v108i5/6.588
Abstract: We investigated proportionalities in the enterprise structures of 125 South African towns through examining four hypotheses, (1) the magnitude of enterprise development in a town is a function of the population size of the town; (2) the size of an enterprise assemblage of a town is a function of the town’s age; (3) there are statistically significant relationships, and hence proportionalities, between the total number of enterprises in towns and some, if not all, of the enterprise numbers of different business sectors in towns; and (4) the implications of proportionalities have far-reaching implications for rural development and job creation. All hypotheses were accepted on the basis of statistically significant (p < 0.05) correlations, except for the second hypothesis – the age of a town does not determine the size of its enterprise assemblage. Analysis for the fourth hypothesis suggested that there are two broad entrepreneurial types in South African towns: ‘run-of-the-mill’ entrepreneurs and ‘special’ entrepreneurs, which give rise to different enterprise development dynamics. ‘Run-of-the-mill’ enterprises are dependent on, and limited by, local demand and if there is only a small demand, the entrepreneurial space is small. By comparison, ‘special’ enterprises have much larger markets because their products and/or services are exportable. We propose that the fostering of ‘special’ entrepreneurs is an imperative for local economic development in South African towns.
The enterprise ecology of towns in the Karoo, South Africa

Abstract: Two concepts, (1) companies are ‘living’ entities and (2) ‘company ecology’, stimulated our hypothesis that towns are ‘enterprise ecosystems’. This hypothesis cannot be tested directly. However, if it is correct, application of clustering and ordination techniques used frequently in studies of natural ecosystems, should reveal clusters of towns that are statistically significantly different (p < 0.05). A dataset of 47 towns in the Karoo, South Africa served as study material and their enterprise assemblages were profiled through the use of a simple method based on the examination of telephone directories. Clustering and ordination techniques revealed six different clusters of towns at a correlation coefficient level of 0.65 and the clusters differed significantly (p < 0.05) in some respects. The agricultural products and services, the tourism and hospitality, and the trade sectors were particularly important in defining these clusters. We concluded that enterprise ecology is a valid concept and towns are ‘ecosystems’ that also cluster together in larger groupings. An array of potentially important techniques and approaches for the study of business development in towns now provide support to, and intriguing questions confront, academic and practical researchers of enterprise development in towns.

Concentración empresaria y eficiencia en el autotransporte urbano de Buenos Aires**
Gutiérrez,Andrea Inés;
EURE (Santiago) , 2004, DOI: 10.4067/S0250-71612004009100007
Abstract: this work evaluates the applied regulatory reform to the public bus transport in buenos aires in 1994, according to the level of satisfaction reached in the fulfillment of its fundamental intention, that is to say, to increase the efficiency of the bus transport system, and to confront these results with the evolution of the firms structure of the industry. the results of the case in study indicate that the new regulation framework prepared a strong process of enterprise concentration, that did not manage to be accompanied by an increase of the efficiency of the industry.
