This paper examines the democratisation of education in South Africa within the context of the policy of educational decentralisation with regards to key policy texts, namely, the South African Schools Act (SASA) and the National Norms and Standards for School Funding (NNSSF). It begins by exploring the concept of decentralisation with specific reference to the notions of democratisation and participation. This leads to an examination of these concepts within the South African context. The final section examines the policy impact of participation and democratisation in relation to the powers and functions of School Governing Bodies (SGBs) by considering four illustrative examples, namely, religion, language, admissions and teacher employment. The paper concludes by considering the policy gap between policy rhetoric and practice in relation to attempts to entrench democracy and participation, and enhance participation at the school level. 相似文献

This paper deals with the estimation of crest settlement in a concrete face rockfill dam （CFRD）, utilizing intelligent methods. Following completion of dam construction, considerable movements of the crest and the body of the dam can develop during the first impoundment of the reservoir. Although there is vast experience worldwide in CFRD design and construction, few accurate experimental relationships are available to predict the settlement in CFRD. The goal is to advance the development of intelligent methods to estimate the subsidence of dams at the design stage. Due to dam zonifieation and uncertainties in material properties, these methods appear to be the appropriate choice. In this study, the crest settlement behavior of CFRDs is analyzed based on compiled data of 24 CFRDs constructed during recent years around the world, along with the utilization of gene ex- pression programming （GEP） and adaptive neuro-fuzzy inference system （ANFIS） methods. In addition, dam height （H）, shape factor （St）, and time （t, time after first operation） are also assessed, being considered major factors in predicting the settlement behavior. From the relationships proposed, the values ofR2 for both equations of GEP （with and without constant） were 0.9603 and 0.9734, and for the three approaches of ANFIS （grid partitioning （GP）, subtractive clustering method （SCM）, and fuzzy c-means clustering （FCM）） were 0.9693, 0.8657, and 0.8848, respectively. The obtained results indicate that the overall behavior evaluated by this approach is consistent with the measured data of other CFRDs. 相似文献
