This study investigates educators' experiences in choosing material for learners in the inclusive classroom setting as clearly stated in chapter one. Chapter two explored the literature on the learning and teaching support materials and the processes involved. The definition of learning and teaching support materials was explored. The kinds, importance and role of learning and teaching support, were discussed and the role is seen as a vehicle which enhances the awareness for expression and opportunities to capture evidence of learners knowledge. Guidelines to consider in the process of selecting learning and teaching support materials and the utilization thereof, as well as the funding of learning and teaching support materials received attention. This chapter further explored the inclusive classroom where inclusion is defined; the nature of inclusive classroom was discussed. The benefits and the criticism of inclusive classroom settings were also explored. In chapter three, the empirical research design used in the study is discussed. Focus group interviews in qualitative study were used to explore educators' experiences in choosing learning and teaching support material in inclusive classroom settings. Chapter four highlighted the research methods used to investigate the problems of this study. The application of the focus interview was explained in detail because the focus group was used for the collection of data which was analysed and interpreted. The data revealed that educators experience a number of difficulties in choosing learning and teaching support materials for learners in inclusive classroom settings. The last chapter concludes the study with recommendations on the way to assist educators in choosing materials for learners in the inclusive classroom setting. / Thesis (M.Ed.)--North-West University, Vaal Triangle Campus, 2008.

This thesis seeks to explore the points of dissonance and resonance around the understanding and deployment of the term 'religion' between Human Rights Watch, and the government of the People's Republic of China. In doing this, it is highlighted that a fundamental disjunction exists in the meaning of, and the boundaries of, the word 'religion' between these two groups. The space that this difference creates makes discussions on religion and religious freedom between these two groups extremely problematic, primarily because Human Rights Watch seeks to protect the right to religious freedom of groups and individuals that the Chinese government does not consider ‘religion’, but that Human Rights Watch demands they should. This thesis addresses the question of the role of social and cultural relativism in the defining, and the subsequent role in defending, of the term and contents of 'religion'.

The introduction of Magnetic Resonance (MR) Imaging in treatment planning for radiotherapy of prostate cancer give rise to new challenges in defining the treatment volume, or the target. Imaging with MR have several advantages, especially better soft-tissue contrast, compared with the standard image modality, Computed Tomography (CT). The purpose of this project was to determine how the target definition varies with the choice of image modality and the systematic differences between them. The purpose was also to determine how the inter- and intra physician variability influences the delineation, depending on which image modality that is used. In the project, five physicians delineated the prostate gland on CT and MR images for nine patients. The physicians had no information of which image series that was connected, and were thus delineating independent. After the delineation, the CT and MR image series was set in the same geometrical coordinate system in the treatment planning system Oncentra. The target delineations were analysed by comparing the radial distances from the centre of mass in different directions, such as anterior, posterior, etc. The radial distances were later used to evaluate the variability of the delineations and to determine the inter and intra physician variability in different directions of the targets. ANOVA was also preformed to determine if there is a significant difference between the parameters, as the image modality and the image modalities influence on the physicians delineations. A model was made to investigate how the MR delineations differ from a CT defined volume that 95% of the delineations cover, called the ideal CT delineation. From this, the median deviation in different directions  was analysed and it was found that the median value of the MR delineations in different directions was between -0.10-2.27 mm larger than the ideal CT delineation. The fluctuations between the delineations was, however, large. The target volume was larger for CT defined volumes in 87% of the cases, compared with MR targets. The inter physician variability was found to be between 0.54-2.17 mm for the CT based delineations and 0.68-2.08 mm for the MR based target delineations. The intra physician variability was larger than the inter physician variability, between 0.74-2.51 mm for CT based delineations and 0.85-1.45 mm for MR based delineations. The median variability of the delineations were not uniform around the target volume but were larger for example in the superior and inferior directions and had its minimum in the posterior direction. The ANOVA tests showed a significant difference between MR and CT based target delineations, it also shows a relation between the delineating physician and the image modality, meaning that the physicians are delineating different on CT and MR images. Target volumes defined on MR images are in general smaller than the CT defined targets. The soft tissue contrast in MR images makes the delineating process easier, however, the analysis of the variability in this project indicates that the variations of MR based target delineations are larger than the CT based. The large variation of the delineations implies that clinical tests should be made to ensure a proper dose coverage before MR could be used as the only image modality in radiotherapy treatment planning of prostate cancer.

In this thesis jet production and cosmological constraints on decaying dark matter are studied. The powerful framework of effective field theory is applied in both cases to further our knowledge of particle physics. We first discuss how to apply the Soft Collinear Effective Theory (SCET) for calculating hadronic jet production rate. By applying SCET power counting, we develop a consistent approach to perform phase space integrations. This approach is then successfully applied to one-loop calculations with regard to a variety of jet algorithms. This allows us to study if the soft contribution can be factorized from the collinear ones. In particular we point out the connection between such factorization and the choice of ultraviolet regulator. We then further our study of the (exclusive) kt and C/A jet algorithms in SCET with the introduction of an additional regulator. Regularizing the virtualities and rapidities of graphs in SCET, we are able to write the next-to-leading-order dijet cross section as the product of separate hard, jet, and soft contributions. We show how to reproduce the Sudakov form factor to next-to-leading logarithmic accuracy previously calculated by the coherent branching formalism. Our resummed expression only depends on the renormalization group evolution of the hard function, rather than on that of the hard and jet functions as is usual in SCET. Finally we present a complete analysis of the cosmological constraints on decaying dark matter. For this, we have updated and extended previous analyses to include Lyman-alpha forest, large scale structure, and weak lensing observations. Astrophysical constraints are not considered in this thesis. The bounds on the lifetime of decaying dark matter are dominated by either the late-time integrated Sachs-Wolfe effect for the scenario with weak reionization, or CMB polarisation observations when there is significant reionization. For the respective scenarios, the lifetimes for decaying dark matter are constrained by Gamma^{-1} > 100 Gyr and (f*Gamma)^{-1} > 5.3 x 10^8 Gyr (at 95.4% confidence level), where the phenomenological parameter f is the fraction of decay energy deposited into the baryonic gas. This allows us to constrain particle physics models with dark matter candidates, by analyzing effective operators responsible for the dark matter decays into Standard Model particles.

Syftet med studien är att undersöka vilka förutsättningar tre skolors pedagoger har för arbetet med särskilda behov. Detta med utgångspunkt i lärares, specialpedagogers/elevassistent och rektorers förhållningssätt till barn i behov av särskilt stöd. I forskningsarbetet synliggörs det specialpedagogiska arbetet, men också den kunskap som finns i relation till barn i behov av särskilt stöd, rättigheter och skyldigheter mellan skola och individ. Vår studie har tre forskningsfrågor som i sin tur ligger som grund i studien och inför insamlingen av arbetsstoff. Genom kvalitativa intervjuer samlade vi kunskap om pedagogers vardagsarbete. Med utgångspunkt i pedagogers utsagor har vi tillsammans diskuterat resultatet och tagit fasta på tre problemområden. Det innefattar tidskrävande arbete, bristande kompetens och skolans ekonomi i förhållande till arbetet med barn i behov av särskilt stöd. Vi beskriver även nya forskningsfrågor så som varför antalet barn med särskilda behov ökar i dagens skolor? Hur kan vi få in mer pengar i skolan och hur dessa pengar kan användas i förhållande till det specialpedagogiska arbetet? Då vi tog del av pedagogers erfarenheter skapade vi oss också beredskap inför vårt kommande yrke inom det specialpedagogiska arbetet i skolan som vi alla kommer möta.
