Since 1994 the demand to educate learners with special needs within mainstream classrooms in South Africa has continued to grow and the implementation of inclusive education is in the final process of legislation. The result has been that an increasing number of learners with disabilities, including intellectual disabilities, are being included in mainstream classrooms. International research indicates that it is especially the acceptance of learners with intellectual disabilities that seems to raise the most sensitive issues for teachers within inclusive classrooms. This research study was designed to investigate the stressors related to the specific situation of including a learner with an intellectual disability in mainstream classrooms and the subsequent stress levels of teachers in the Gauteng and Western Cape provinces of South Africa. The design and methodology of this study was a combination of quantitative and qualitative methods. Fifty-five teachers were purposefully selected to complete a questionnaire focusing on the effect of potential stressors on teachers when including a learner with an intellectual disability. In-depth structured interviews were conducted with 10 of these teachers. This project is highly significant as policies of inclusion rely on teachers' acceptance of them, belief in their worth, and ability to cope. An understanding of the conditions that are likely to cause teachers most stress during inclusion will allow for more appropriate teacher training and for more focused support to teachers in inclusive classrooms. 相似文献

Although there are clear differences in national policies regarding inclusive education, the international debate has not fully considered their impact on implementation within different countries, for example on teacher education. This paper reports on results from a comparative study of in-service teachers’ attitudes and self-efficacy in implementing inclusive practices in South Africa and Finland and its implications for teacher education in these countries. A sample of 319 South African and 822 Finnish primary and secondary education teachers completed a questionnaire containing a scale measuring sentiments, attitudes and concerns on inclusive education as well as a scale measuring teachers’ self-efficacy in implementing inclusive practices. A comparative analysis indicated that whereas the overall sentiments towards disabilities were positive in both countries, teachers had many concerns about the consequences of including children with disabilities in their classrooms. While the most positive aspect of self-efficacy among the South African teachers was their self-efficacy in managing behaviour, the Finnish teachers saw this as their weakest point. Self-efficacy, in particular efficacy in collaboration, was clearly related to overall attitudes towards inclusion. The implications of these findings for pre-service and in-service teacher education are discussed. 相似文献

Applying natural language processing for mining and intelligent information access to tweets (a form of microblog) is a challenging, emerging research area. Unlike carefully authored news text and other longer content, tweets pose a number of new challenges, due to their short, noisy, context-dependent, and dynamic nature. Information extraction from tweets is typically performed in a pipeline, comprising consecutive stages of language identification, tokenisation, part-of-speech tagging, named entity recognition and entity disambiguation (e.g. with respect to DBpedia). In this work, we describe a new Twitter entity disambiguation dataset, and conduct an empirical analysis of named entity recognition and disambiguation, investigating how robust a number of state-of-the-art systems are on such noisy texts, what the main sources of error are, and which problems should be further investigated to improve the state of the art. 相似文献

This paper reports on the findings of an international comparative research project where the roles of teachers in the implementation of inclusive education in mainstream-classroom settings in South Africa and Finland were investigated. Inclusive education within this project is broadly defined as welcoming all students to general-education schools and classrooms and not segregating students on the basis of ability or other individual or sociocultural characteristics. In this paper a qualitative analysis of Finnish and South African teachers’ day-to-day teaching and learning support practices in their classroom is discussed. Individual and focus-group interviews encouraged teachers to articulate their views in this regard. Initial findings indicate that despite the dissimilar cultural and historical contexts of these two countries, both complex contextual issues and classroom practices based on a medical-deficit understanding of diverse educational needs play a role in Finnish and South African classrooms. 相似文献

Embalming fixatives such as formaldehyde and phenol have been associated with occupational health hazards. While anatomists aim at replacing these chemicals, this seems presently unfeasible in particular for formaldehyde. Furthermore, fixation protocols usually require well-equipped facilities with highly experienced staff to achieve good fixation results in spite of only a minimal use of formaldehyde. Combining these aspects, a technique robust enough to be carried out by morticians is presented, resulting in durable tissues with minimal formaldehyde use. An embalming protocol involving phenoxyethanol was established, using concentrations of 7 and 1.5 Vol% of phenoxyethanol in the fixative and the conservation fluid, respectively. Visual, haptic, histological, and biomechanical properties and their perceived potential to positively influence student learning outcomes were compared to standard embalming techniques. The phenoxyethanol technique provides esthetic, durable, and odorless tissues. Bleaching is less pronounced compared to ethanol- or formaldehyde-based protocols. The tissues remain pliable following the phenoxyethanol-based embalming and can be used for biomechanical experiments to some extent. Phenoxyethanol-fixed tissues are well suited for undergraduate teaching with perceived positive learning outcomes and partly for postgraduate training. Phenoxyethanol tissues provide the option to obtain well-preserved histology samples, similar to those derived from formaldehyde. The provided protocol helps replace the use of phenol and formaldehyde for conservation purposes and minimizes the use of formaldehyde for the initial injection fixation. Phenoxyethanol-based embalming forms an effective alternative to standard embalming techniques for human cadavers. It is simple to use, allowing fixation procedures to be carried out in less sophisticated facilities with non-anatomy staff. 相似文献

Accurate assessment of resting metabolic rate (RMR) is necessary for calorie-based recommendations in diet and exercise training interventions. BodyMetrix? is an ultrasound-based device that provides an estimate of RMR based on body composition, but has not been proven valid or reliable. Therefore, we evaluated the agreement between Katch–McArdle prediction equation used by BodyMetrix?, with indirect calorimetry, Harris–Benedict, WHO, and Sabounchi prediction equations of RMR. In total, 32 men and 22 women were measured for body composition via BodyMetrix? and RMR via indirect calorimetry. All prediction equations demonstrated significantly lower RMR values (p < .001) relative to indirect calorimetry. Katch–McArdle equation strongly correlated with other prediction equations (p < .001), and had a moderate (r = .658, p < .001) correlation with indirect calorimetry. There was a tendency toward underestimation for obese individuals. Therefore, we suggest that estimates from BodyMetrix? may be used as a relative, rather than an absolute measure of RMR. 相似文献

Abstract Previous production function studies analysing the use of information inputs in U.S. manufacturing seem to indicate their large underuse and, implicitly, advocate a policy of increased investment in such inputs. In the present study the degree of underuse of information inputs is reassessed by using techniques similar to those applied in the earlier studies and by using more comprehensive and appropriate alternative methods, i.e. estimating translog functions via the systems approach. By expressing all inputs in monetary terms, comparable marginal (value) products for all factors of production are obtained. The results prove to be highly sensitive to the changes in methodology. The degree of underuse of information inputs seems to have been overstated by previous authors. Our results are likely to be more reliable than previous findings because of the reductions in simultaneity and specification bias which the systems approach entails. Finally, we can say little about policy implications. To assess whether a strategy of increased investment in information inputs should be pursued would require detailed analysis of the supply and demand conditions of these inputs, and of the efficiency of information resource use. 相似文献

The British Index for Inclusion was selected to be used in three primary schools in the Western Cape Province in South Africa in order to develop a South African model to assist in the development of inclusive schools. The Index for Inclusion process entails progression through a series of five developmental phases and this paper, written by Petra Engelbrecht, professor in educational psychology and special education and senior research director at Stellenbosch University, Marietjie Oswald, lecturer in special education at Stellenbosch University, and Chris Forlin, associate professor in special education at the Hong Kong Institute of Special Education, is a reflection of the first two phases. Qualitative data were generated from the consultative process followed in the schools during the first phase and both qualitative and quantitative data from questionnaires regarding the perceptions of all school community members on the inclusive practices or lack thereof in their schools during the second phase. The authors drew out the following five themes from the three sets of data: an inclusive school philosophy; democratic leadership, structures, processes and values; collaboration; addressing learner diversity; and resources. Petra Engelbrecht, Marietjie Oswald and Chris Forlin, all of whom were working on a UNESCO-funded project to trial the use of the Index for Inclusion in South Africa, suggest that these themes provided invaluable insights into both the common and unique complexities, the problems and the assets of the different school communities. The themes are discussed in detail in this article, raising fascinating issues for the development of inclusion in different contexts around the world, and will be used to inform the three remaining phases of the Index for Inclusion process. 相似文献
