The research proposal is to understand and reflect on the evaluative practices of regular teachers and elementary school teachers (1st to 5th year) of the municipality of Extrema – MG, of students with special educational needs. The research problem was delineated from concerns presented by the teachers who work with these students in the schools of the municipality, such as: how to evaluate students with SEN? What notes to assign? These questions led to the search for interlocutors directly involved with the problem, Mainly teachers from municipal schools who attended in regular education the largest number of students with SEN per class. It is about a case study. The work brings together reflections that emerged from the theoretical elaborated and analysis of the data obtained in teachers' reports and the questionnaires answered by them, As well as observations of everyday school life and also of the comparison with the guidance documents of the Municipal Department of Education that are included in the Municipal Plan of Education (2015 to 2024). The conclusions indicate conceptual tensions over the student with disabilities, Their possibilities of learning and their educational evaluation. The analysis of tensions leads to considerations, rather than to conclusions, that they intend to collaborate to deepen the discussions on such an important topic for educators who work with these students and, even more, for themselves. / La valorización de los aprendizados sirve como instrumento dinámico de las prácticas pedagógicas, principalmente cuando el escenario educacional es atravesado por el movimiento de inclusión. La propuesta de la pesquisa es comprender y reflejar sobre las prácticas de evaluación de los professores de enseñanza regular y de la enseñanza fundamental I (1º al 5º año) del Municipio de Extrema MG, utilizados con alumnos con necesidades educacionales especiales. El problema de la investigación fue delineado a partir de preocupaciones presentadas por los professores que actúan con estos alumnos en las escuelas del Municipio, tales como: ¿como evaluar los alunos com NEE? ¿Que notas atribuirle? Estas questiones llevaron a la búsqueda por interlocutores directamente relacionados com el problema, principalmente profesores de las escuelas municipales que atendían en la enseñanza regular el mayor número de alumnos com NEE por salón. Se trata de um estúdio de caso. El trabajo reúne reflexiones que emergieron del referencial teórico elaborado y análisis de los datos obtenidos en relatos de profesoras y en los cuestionarios respondidos por ellas, bien como de observaciones del cotidiano escolar y, todavia, de la comparación con documentos de orientación de la Secretaría Municipal de Educación que constan em el Plan Municipal de Educación (2015 a 2024). Las conclusiones indican tensiones conceptuales sobre el alumno con discapacidad, sus posibilidades de aprendizado y su evaluación educacional. El análisis de esas tensiones lleva a consideraciones, más de que a conclusiones, que tiene la intención de colaborar para aprofundarse en las discusiones a respecto de um tema tan importante para los educadores que trabajan com estos alunos y, más todavia, para ellos propios. / A avaliação das aprendizagens serve como instrumento dinâmico das práticas pedagógicas, principalmente quando o cenário educacional é atravessado pelo movimento de inclusão.

Cette recherche porte sur une catégorie spécifique de travailleurs, les Travailleurs Indépendants Economiquement Dépendants (TIED), qui associent une indépendance juridique à une dépendance économique vis-à-vis d’un seul client. En cumulant des caractéristiques typiques des deux catégories classiques que sont les salariés et les travailleurs indépendants, les TIED s’inscrivent dans une zone grise du marché du travail. A partir d’une étude qualitative menée auprès de TIED français et brésiliens du secteur des Technologies de l’Information, nous nous interrogeons sur la signification sociale de cette forme d’emploi hybride et sur la façon dont elle émerge sur des marchés du travail aussi différents que ceux de la France et du Brésil. L’analyse des conditions de travail des enquêtés permet d’abord de situer les TIED sur un continuum entre salariat déguisé et véritable travail indépendant et de distinguer deux profils-types : les prestataires intégrés à la structure commanditaire et les indépendants en transition. Pour étudier les trajectoires professionnelles de ces travailleurs, nous mobilisons ensuite l’approche par les capabilités d’Amartya Sen (2000) : nous montrons que les parcours des TIED – privés des protections du droit du travail par leur indépendance juridique – reposent sur des processus d'accumulation et de conversion de différents types de ressources en libertés réelles (ou capabilités). De plus, si l’approche de Sen permet d’expliquer les différences de capabilités observées au sein de notre échantillon, nous proposons d’enrichir son cadre d’analyse afin de l’adapter à l’étude de trajectoires socioprofessionnelles. Les analyses réalisées nous conduisent enfin à distinguer deux groupes d’enquêtés, les "TIED réticents" et les "TIED épanouis" : les TIED réticents, plus nombreux au Brésil, expriment un attachement fort au salariat, alors que les TIED épanouis voient dans la position de TIED une façon d’échapper à des emplois décevants et trouvent souvent avantage à une situation qui leur offre plus d’autonomie que le salariat et plus de confort que la véritable indépendance. En nous appuyant sur les travaux de Fraser (2010) et Boltanski et Chiapello (2011), nous montrons comment le positionnement des TIED épanouis contribue indirectement à la remise en cause du rôle de l’Etat social.Les TIED apparaissent en définitive comme une figure emblématique d’un processus ambivalent d’individualisation qui contribue à l’émergence d’un sujet en quête d’autonomie, délié de ses appartenances traditionnelles, tout en favorisant une confrontation directe de l’individu avec le marché qui accroît les inégalités. Dès lors, si les désirs d’émancipation et d’autonomie des TIED épanouis nous semblent devoir être pris au sérieux, une réflexion s’impose sur les mesures susceptibles d’étendre les capabilités des individus tout en luttant contre l’exacerbation des inégalités et en préservant un système de mutualisation des risques fondé sur la solidarité. / This research deals with a specific category of workers, the Economically Dependent Self-employed Workers (EDSW), who associate legal independence with an economic dependence upon a single client. Combining typical characteristics of two traditional labor categories, wage-labor and self-employment, EDSW fall within a grey zone of the labor market. Starting from a qualitative survey conducted among French and Brazilian EDSW from the Information Technology sector, we question the social significance of this hybrid employment form and the way it emerges in labor markets as dissimilar as those of France and Brazil. At first, the analysis of EDSW working conditions enables to place them on a continuum between disguised wage-labor and real self-employment and to identify two typical profiles: service providers integrated to the client structure and transitioning self-employed workers. To study their occupational path, we then mobilize Amartya Sen’s capability approach (2000): we show that the careers of EDSW – deprived of labor law protection by their self-employment status – rely on accumulation and conversion processes of various resources types into real freedom (or capabilities). Moreover, if Sen's approach helps explaining the observed differences in capabilities within our sample, we propose to enrich its analytical framework in order to adapt it to socio professional path study. Finally, the conducted analyzes lead us to split our sample into two groups: the ‘reluctant EDSW’ and the ‘fulfilled EDSW’. The reluctant EDSW, more numerous in Brazil, express a strong attachment to wage-labor, whereas the fulfilled EDSW see in EDSW position a way to exit disappointing jobs and often find benefits in a situation which offers them more autonomy than wage-labor and greater comfort than actual self-employment. Mobilizing the theoretical contributions of Fraser (2010) and Boltanski and Chiapello (2011), we demonstrate how the positioning of the fulfilled EDSW contributes to indirectly challenge the welfare state’s role.EDSW ultimately appear as an icon of an ambivalent process of individualization which contributes to the emergence of a subject who is seeking for autonomy, relieved from its traditional affiliations, while simultaneously promoting a direct confrontation of the individuals with the market that increases inequalities. Therefore, if the fulfilled EDSW’s wishes for emancipation and autonomy should be seriously considered, a reflection is needed on measures that may increase individual capabilities while struggling against increasing inequalities and maintaining a system of risks management based on solidarity. / Essa tese está dedicada a uma categoria específica de trabalhadores, os Trabalhadores Autônomos Economicamente Dependentes (TAEDs), que cumulam uma autonomia jurídica com uma situação de dependência econômica em relação a um único cliente. Ao associar características típicas das duas categorias clássicas que são os assalariados e os trabalhadores autônomos, os TAEDs inscrevem-se numa zona cinzenta do mercado de trabalho. A partir de uma pesquisa qualitativa realizada com TAEDs franceses e brasileiros do setor de Tecnologia da Informação, perguntamo-nos acerca do significado social dessa forma híbrida de trabalho e da sua emergência nos mercados de trabalho tão distintos da França e do Brasil. A análise das condições de trabalho dos entrevistados possibilita primeiro situar os TAEDs num continuum entre emprego assalariado e verdadeiro trabalho autônomo e diferenciar dois perfis: os prestadores integrados na estrutura cliente e os autônomos em transição. Para estudar as trajetórias profissionais desses trabalhadores, mobilizamos, em seguida, a abordagem pelas capacidades de Amartya Sen (2000): mostramos que os percursos dos TAEDs – que são privados das proteções trabalhistas pela sua autonomia jurídica – dependem de processos de acumulação e conversão de distintos tipos de recursos em liberdades reais (ou capacidades). Além disso, se a abordagem de Sen permite explicar as diferenças de capacidades observadas na nossa amostra, propomos enriquecer o seu marco de análise para adaptá-lo ao estudo de trajetórias socioprofissionais. As análises realizadas nos levam finalmente a distinguir dois grupos de entrevistados, os “TAEDs reticentes” e os “TAEDs satisfeitos”: os TAEDs reticentes, mais numerosos no Brasil, expressam um forte apego ao emprego assalariado enquanto os TAEDs satisfeitos veem na posição de TAED uma forma de se livrarem de empregos decepcionantes e, na maioria dos casos, creem vantajosa uma situação que oferece uma autonomia maior que o emprego assalariado e um conforto maior que o trabalho verdadeiramente autônomo. A partir das obras de Fraser (2010) e Boltanski e Chiapello (2011), mostramos que o posicionamento dos TAEDs satisfeitos questiona indiretamente o papel do Estado social. Os TAEDs aparecem então como uma figura emblemática de um processo ambivalente de individualização que contribui para a emergência de um sujeito que busca autonomia e está livre de seus pertencimentos tradicionais, ao mesmo tempo em que favorece um confronto direto do indivíduo com o mercado que aumenta as desigualdades. Se achamos que os desejos de emancipação e autonomia dos TAEDs satisfeitos têm que ser levados a serio, é necessário refletir sobre as medidas que poderiam expandir as capacidades dos indivíduos, lutando contra o aumento das desigualdades e preservando um sistema solidário de gestão dos riscos.

Thesis (PhD)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The special needs community is in the midst of a philosophical and physical shift from a segregated system to an integrated system, not only in placement, but more importantly, in terms of learning and affording learners with special needs access to mainstream curricular materials. Mathematical modelling, or challenging mathematics problems solved in small groups, is part of the Australian mainstream curriculum. The purpose of the study was to investigate the way special needs learners learn mathematics from a modelling learning environment. To do this, it was necessary to identify the critical characteristics of the best practice in teaching and learning for learners with special needs, and the critical features of modelling. One theory of learning that has the capacity to promote special needs learners' interaction with mathematical modelling is Feuerstein’s theory of Structural Cognitive Modifiability. A hypothetical learning trajectory was designed for special needs learners at middle school according to general design principles from theory, which was adapted to the learning characteristics of the class. The learning environment comprised of three challenging modelling tasks, together with recommended implementation and support conditions in the classroom. Specifically, the research sought to investigate the ways in which special needs educators can support the higher reasoning processes of special needs students during modelling through design in general, and through mediation specific to each learner. The research took the form of a qualitative study, combining the phases of design-based research with a multiple case study approach. Three cases were analysed in depth. Empirical data were collected through a range of qualitative methods, which included data from student files, field observations, video and audio recordings, focus group interviews with students, and the input of various collaborators across the different phases of planning, design, implementation, and revision. Data were coded and analysed inductively according to emerging patterns and themes. Findings suggest that the use of modelling was successful when implemented with certain characteristics defined in the literature, and that it enabled learners to learn mathematics and also to develop additional outcomes such as social skills and language. During this study, learners' higher-order reasoning was supported through dynamic assessment and subsequent mediation. / AFRIKAANSE OPSOMMING: Die onderwysgemeenskap vir leerders met spesiale behoeftes bevind hulle in die middel van filosofiese en fisiese verskuiwings van 'n geskeide sisteem na 'n geïntegreerde sisteem. Dit omvat die plasing van leerders, maar meer belangrik ook die bemoontliking van toegang van hierdie leerders tot hoofstroom kurrikulêre materiale. Wiskundige modellering, en uitdagende wiskundeprobleme wat deur leerders in klein groepies opgelos word, is deel van die Australiese hoofstroomkurrikulum. Die doel van die studie was om die wyse te ondersoek waarvolgens leerders met spesiale behoeftes wiskunde in 'n modelleringsomgewing leer. Dit is gedoen deur die belangrike kenmerke van beste praktyk vir onderrig en leer in spesiale onderwys, asook die kritiese kenmerke van modellering, te vind. Een leerteorie wat die interaksie van leerders met spesiale behoeftes met wiskunde bevorder, is Feuerstein se teorie van Strukturele Kognitiewe Modifieerbaarheid. 'n Hipotetiese leertrajek was ontwerp vir leerders met spesiale behoeftes op middelskoolvlak. Empiriese data is deur 'n reeks kwalitatiewe aksies: data van studentelêers, veldwaar-nemings, video en klankopnames, fokusgroeponderhoude met studente, asook die insette van verskeie medewerkers oor die verskillende fases van beplanning, ontwerp, implementering en hersiening gegenereer. Die spesifieke leerkenmerke van hierdie leerders volgens algemeen-teoretiese en lokaalgekontekstualiseerde ontwerpbeginsels is nagekom. Die leertrajek het bestaan uit drie uitdagende modelleringsprobleme met aanbevole implementering en ondersteuningsriglyne in die klaskamer. Die navorsing het spesifiek gesoek na wyses waarop hierdie leerders se hoër beredeneringsvaardighede deur hul onderwysers, volgens elkeen se eie behoefte gedurende modellering, deur ontwerp in die algemeen en mediasie in die besonder, ondersteun kan word. Die navorsing, 'n kwalitatiewe studie, was gekombineer met fases van ontwikkelingsgebaseerde ontwerp wat uitgespeel het in 'n veelvuldige gevallestudiebenadering. Drie gevalle is in diepte ondersoek. Data was induktief gekodeer en geanaliseer volgens ontluikende patrone en temas. Bevindinge wys uit dat die gebruik van modellering suksesvol was wanneer die implementering volgens spesifieke kenmerke in die literatuur was. Dit het leerders instaat gestel om wiskunde te leer asook om addisionele uitkomste soos sosiale vaardighede en taal te ontwikkel. In hierdie studie is hoër-orde denke ondersteun deur dinamiese assessering en voortspruitende mediasie.

L’approche des capabilités a été caractérisée par un développement fulgurant au cours des vingt-cinq dernières années. Bien que formulée à l’origine par Amartya Sen, détenteur du Prix Nobel en économie, Martha Nussbaum reprit cette approche dans le but de s’en servir comme fondation pour une théorie éthico-politique intégrale du bien. Cependant, la version de Nussbaum s’avéra particulièrement vulnérable à plusieurs critiques importantes, mettant sérieusement en doute son efficacité globale. À la lumière de ces faits, cette thèse vise à évaluer la pertinence théorique et pratique de l’approche des capabilités de Nussbaum, en examinant trois groupes de critiques particulièrement percutantes formulées à son encontre. / The capabilities approach has seen significant development over the past quarter century, branching out into a variety of fields and directions. Originally developed by Nobel Prize Laureate Amartya Sen, Martha Nussbaum has sought to extend this approach beyond its mainly instrumental role into a tangible foundation for a full-fledged ethical-political theory of the good. However, this move has attracted a great number of criticisms levelled against Nussbaum’s specific version of the capabilities approach. In this thesis, I identify three main groups of observations under which said criticisms can be classified, and assess their respective strength and tenability.

This thesis focuses on the theme of the journey and the changes that occur in the socio-historical context of the Great Depression as well as in John Steinbeck's The Grapes of Wrath. The thesis is an expository piece on road literature, its features and how the chosen novel has earned its rightful place in the American oeuvre, specifically that of road literature. The thesis is separated into two major parts. The former part provides the reader with a socio- historical context of the Great Depression as well as a background on the historical patterns of the 'journey' in America and how these two aspects are interrelated in the context of this thesis. The latter part constitutes the analysis of John Steinbeck's The Grapes of Wrath by including the authorial relationship to the novel and the many aspects of the novel as studied through the scope of road literature. This part is further expanded by a close-up analysis of the changes in identity of characters in The Grapes of Wrath. The primary focus is on the notion of change and how it is connected to the notion of the road, including how the human being stands between these notions and is transformed in the process. Keywords: change, mobility, flight, escape, John Steinbeck, The Grapes of Wrath, American Dream, hope, depression, 1930s, Great...

The introduction of this diploma thesis summarizes the production of , and it identifies the two following layers of authorship. The first layer is the fictional authorship of Jara Cimrman; the second layer is the authorship of the Cimrmanologists and their so-called (or fictional) reconstructions of Cimrman's work. The introduction further discusses the importance of the radio show , which gave birth to the character of Jara Cimrman. Finally, the introduction analyses various aspects of Cimrman and his mystifying character. The core of this thesis consists of an analysis of Cimrman and his relation to Czech Dream. It also studies the Czech dream and its development. The second chapter provides a study based on the play , which is looking at the relation between Cimrman and Czech history and the national myth. The beginning of this chapter offers an overview of the history of the . The chapter then continues with an analysis of Cimrman's play with a special attention to its unusual political dimension. The third chapter studies the connections between Cimrman, or his creators, and Czech national consciousness and Czech culture as they are reflected in Cimrman's play . The play is set in the context of Kainar's poem , Klusak and Remunda's film , Macura's essay , and Kaspar's book .

The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. Therefore, the SEN can be considered as a vital factor for a stable casting process and the steel quality. In addition, the steelmaking processes occur at high temperatures around 1873 K, so the interaction between the refractory materials of the SEN and molten steel is unavoidable. Therefore, the knowledge of the SEN behaviors during preheating and casting processes is necessary for the design of the steelmaking processes  The internal surfaces of modern SENs are coated with a glass/silicon powder layer to prevent the SEN graphite oxidation during preheating. The effects of the interaction between the coating layer and the SEN base refractory materials on clogging were studied. A large number of accretion samples formed inside alumina-graphite clogged SENs were examined using FEG-SEM-EDS and Feature analysis. The internal coated SENs were used for continuous casting of stainless steel grades alloyed with Rare Earth Metals (REM). The post-mortem study results clearly revealed the formation of a multi-layer accretion. A harmful effect of the SENs decarburization on the accretion thickness was also indicated. In addition, the results indicated a penetration of the formed alkaline-rich glaze into the alumina-graphite base refractory. More specifically, the alkaline-rich glaze reacts with graphite to form a carbon monoxide gas. Thereafter, dissociation of CO at the interface between SEN and molten metal takes place. This leads to reoxidation of dissolved alloying elements such as REM (Rare Earth Metal). This reoxidation forms the “In Situ” REM oxides at the interface between the SEN and the REM alloyed molten steel. Also, the interaction of the penetrated glaze with alumina in the SEN base refractory materials leads to the formation of a high-viscous alumina-rich glaze during the SEN preheating process. This, in turn, creates a very uneven surface at the SEN internal surface. Furthermore, these uneven areas react with dissolved REM in molten steel to form REM aluminates, REM silicates and REM alumina-silicates. The formation of the large “in-situ” REM oxides and the reaction of the REM alloying elements with the previously mentioned SEN´s uneven areas may provide a large REM-rich surface in contact with the primary inclusions in molten steel. This may facilitate the attraction and agglomeration of the primary REM oxide inclusions on the SEN internal surface and thereafter the clogging. The study revealed the disadvantages of the glass/silicon powder coating applications and the SEN decarburization. The decarburization behaviors of Al2O3-C, ZrO2-C and MgO-C refractory materials from a commercial Submerged Entry Nozzle (SEN), were also investigated for different gas atmospheres consisting of CO2, O2 and Ar. The gas ratio values were kept the same as it is in a propane combustion flue gas at different Air-Fuel-Ratio (AFR) values for both Air-Fuel and Oxygen-Fuel combustion systems. Laboratory experiments were carried out under nonisothermal conditions followed by isothermal heating. The decarburization ratio (α) values of all three refractory types were determined by measuring the real time weight losses of the samples. The results showed the higher decarburization ratio (α) values increasing for MgO-C refractory when changing the Air-Fuel combustion to Oxygen-Fuel combustion at the same AFR value. It substantiates the SEN preheating advantage at higher temperatures for shorter holding times compared to heating at lower temperatures during longer holding times for Al2O3-C samples. Diffusion models were proposed for estimation of the decarburization rate of an Al2O3-C refractory in the SEN. Two different methods were studied to prevent the SEN decarburization during preheating: The effect of an ZrSi2 antioxidant and the coexistence of an antioxidant additive and a (4B2O3 ·BaO) glass powder on carbon oxidation for non-isothermal and isothermal heating conditions in a controlled atmosphere. The coexistence of 8 wt% ZrSi2 and 15 wt% (4B2O3 ·BaO) glass powder of the total alumina-graphite refractory base materials, presented the most effective resistance to carbon oxidation. The 121% volume expansion due to the Zircon formation during heating and filling up the open pores by a (4B2O3 ·BaO) glaze during the green body sintering led to an excellent carbon oxidation resistance. The effects of the plasma spray-PVD coating of the Yttria Stabilized Zirconia (YSZ) powder on the carbon oxidation of the Al2O3-C coated samples were investigated. Trials were performed at non-isothermal heating conditions in a controlled atmosphere. Also, the applied temperature profile for the laboratory trials were defined based on the industrial preheating trials. The controlled atmospheres consisted of CO2, O2 and Ar. The thicknesses of the decarburized layers were measured and examined using light optic microscopy, FEG-SEM and EDS. A 250-290 μm YSZ coating is suggested to be an appropriate coating, as it provides both an even surface as well as prevention of the decarburization even during heating in air. In addition, the interactions between the YSZ coated alumina-graphite refractory base materials in contact with a cerium alloyed molten stainless steel were surveyed. The YSZ coating provided a total prevention of the alumina reduction by cerium. Therefore, the prevention of the first clogging product formed on the surface of the SEN refractory base materials. Therefore, the YSZ plasma-PVD coating can be recommended for coating of the hot surface of the commercial SENs. / <p>QC 20111014</p>

Although there has been increasing research on HIV/AIDS and children, albeit mostly outside the school environment, most research in the area tends to view 'children as objects' (Christensen and James, 1999) in the research process whereby the change in the child is what is being observed. This view lessens the role of the child and as such means that the results are inadequate - mostly the researcher's perspective is represented. In Zimbabwe, with an estimated 1.1 million AIDS orphans and 115,000 children under 14 living with HIV/AIDS, not much empirical research has been conducted in school settings where they spend most of their time; the complexities of infected and affected students' experiences within the school-home-community spheres are mostly inferred due to lack of empirical research. Using Bronfenbrenner's Ecological System's Theory and the Capability Approach to adopt a holistic psychosocio-cultural lens, the research aims to understand the experiences of infected and affected students from their perspectives within their school, home and community environments. Added to observations, in-depth interviews based on data collected using photography, drawings, timelines, sociograms and student diaries were conducted with 65 boys and 27 girls aged 10 -13 years from a rural primary school during the months of August to December 2011. In-depth interviews were also conducted with 161 parents and caregivers. Also interviewed were 13 stakeholders comprising of a Senior Research Officer within the Ministry of Education, District Education Officer, 5 Teachers and their Principal, a District Councilor, the Chief, a village head, a local Baptist Minister and a research staff person from, FACT, a local NGO that works with AIDS orphans. Among children, findings point to dilapidating issues of stigma, abandonment, unaddressed emotional and physical needs; children relied on each other's advice more than that of teachers and caregivers. Among the adult community, the education authorities and community leaders who are custodians of their education, ignorance about infected and affected children is astounding. An ageing population of caregivers is barely able to deal with the complexities of infected children. Religion has a powerful negative influence on addressing HIV/AIDS issues. Teachers, citing taboo issues about sex and the fact that HIV/AIDS is not an exam at the school, refused to broach the subject. Education Officials at the time clearly pointed out that there has been no research nor any plans yet to address this population and their needs. Further research will need to be conducted for educational planning that will be most effective in implementing meaningful changes for this group and other rural primary school children.

For a long time, inclusion or inclusive education (IE) has been high on the agenda both internationally and in Sweden, not least since the signing of the Salamanca Declaration in 1994 and the ratification of the United Nations Convention on the Rights of Persons with Disabilities in 2006. These call for inclusion to be the norm and are guided by the principle that all pupils, regardless of needs, feel that their social, emotional and academic needs are being met. Since the introduction of Lgr11 (2011), the most recent Swedish curriculum, special educational needs (SEN) should be seen as arising out of educational environments and methods that are not adapted enough to be accessible to a wide diversity of pupils. Despite a significant body of research into inclusive education, several researchers raised that few studies focused on the pupil perspective, few were collaborative and few focused on all pupils, that is to say, their focus lies only on pupils with SEN. Arguably, selecting certain groups to investigate goes against the ethos of inclusion and risks missing information from pupils experiencing difficulties that are not yet identified.  When considering factors impacting feelings of inclusion, many studies have raised the importance of socio-emotional functioning alongside academic self-concept. This collaborative study looks at how included pupils in a free school in Stockholm feel, with a focus on whether there is a difference between the pupils’ perception of inclusion depending on whether they have self-reported SEN or not, what grade they are in and their gender. This is measured using a new instrument, the ‘Perception of Inclusion Questionnaire (PIQ) - student version’, which is also being validated as a tool for measuring inclusion in Sweden. Results indicate clearly that pupils with SEN feel significantly less included than their typically-developing peers across all three scales, emotional inclusion, social inclusion and academic self-concept. In addition, grade has an impact, with pupils in Grade 8 having lower feelings of emotional inclusion, social inclusion and academic self-concept than in Grade 5. This difference was apparent for all pupils but the effect was greater in pupils with SEN. Gender returned insignificant results on all three scales. Another interesting result is that more pupils self-report actual or suspected SEN than the school reports, indicating that there are a number of pupils with difficulties who would be overlooked in studies that do not include all pupils. The Swedish version of the PIQ for Students has been validated.

The results showed the higher decarburization ratio (α) values increasing for MgO-C refractory when changing the Air-Fuel combustion to Oxygen-Fuel combustion at the same AFR value. It substantiates the SEN preheating advantage at higher temperatures for shorter holding times compared to heating at lower temperatures during longer holding times for Al2O3-C samples. Diffusion models were proposed for estimation of the decarburization rate of an Al2O3-C refractory in the SEN. Two different methods were studied to prevent the SEN decarburization during preheating: The effect of an ZrSi2 antioxidant and the coexistence of an antioxidant additive and a (4B2O3 ·BaO) glass powder on carbon oxidation for non-isothermal and isothermal heating conditions in a controlled atmosphere. The coexistence of 8 wt% ZrSi2 and 15 wt% (4B2O3 ·BaO) glass powder of the total alumina-graphite refractory base materials, presented the most effective resistance to carbon oxidation. The 121% volume expansion due to the Zircon formation during heating and filling up the open pores by a (4B2O3 ·BaO) glaze during the green body sintering led to an excellent carbon oxidation resistance. The effects of the plasma spray-PVD coating of the Yttria Stabilized Zirconia (YSZ) powder on the carbon oxidation of the Al2O3-C coated samples were investigated. Trials were performed at non-isothermal heating conditions in a controlled atmosphere. Also, the applied temperature profile for the laboratory trials were defined based on the industrial preheating trials. The controlled atmospheres consisted of CO2, O2 and Ar. The thicknesses of the decarburized layers were measured and examined using light optic microscopy, FEG-SEM and EDS. A 250-290 μm YSZ coating is suggested to be an appropriate coating, as it provides both an even surface as well as prevention of the decarburization even during heating in air. In addition, the interactions between the YSZ coated alumina-graphite refractory base materials in contact with a cerium alloyed molten stainless steel were surveyed. The YSZ coating provided a total prevention of the alumina reduction by cerium. Therefore, the prevention of the first clogging product formed on the surface of the SEN refractory base materials. Therefore, the YSZ plasma-PVD coating can be recommended for coating of the hot surface of the commercial SENs.
