The aim of this qualitative study was to description and interpretation of experiences and perceptions of teachers working with students who have challenging behaviours in various types of school settings in Poland. Teachers’ experiences and perceptions provided insights and understandings into action strategies, in the case of the teachers who were interviewed, their assessing student difficulties and the effectiveness of various behavioural interventions. The data obtained from teacher interviews revealed their classroom management practices as well as their perceptions on the efficacy of their respective schoolwide practices for supporting students with behaviour support needs.

Diese qualitative Studie untersucht den schulischen Alltag von drei Jungen mit Fragilem-X- Syndrom. Das Fragile-X-Syndrom ist die häufigste bekannte erbliche Ursache von geistiger Behinderung und wird mit einer Reihe von charakteristischen Eigenschaften assoziiert. Dazu zählen vor allem physische, kognitive und psychosoziale Merkmale. Mithilfe der Ethnografie mit teilnehmender Beobachtung im schulischen Umfeld der Schüler werden die Bedingungen herausgearbeitet, die das Fragile-X-Syndrom der Schüler „sichtbar“ machen. Diese Bedingungen sind vor allem durch den jeweiligen Kontext geprägt, welcher sich aus dem Ausmaß der Hilfestellungen, der Struktur der Anforderungen und der räumlichen und organisatorischen Gestaltung der Umgebung zusammensetzt. Menschen mit Fragilem-X-Syndrom dürfen nicht nur als Träger eines genetischen Syndroms angesehen werden, sondern auch als Mitglieder sozialer Gruppen und Gemeinschaften, an deren immanenten Regeln sie ihr Handeln ausrichten. Die institutionellen und sozialen Bedingungen auf der Ebene des Klassenraums mit seinen jeweiligen Teilnehmerinnen und Teilnehmern bilden die Grundlage für eine soziale Konstruktion des Fragilen-X- Syndroms in der Schule. Diese Annahme ist die Voraussetzung für einen Verstehensprozess, der das Syndrom nicht nur als Ursache einer Behinderung ansieht, sondern vielmehr die Handlungen und performativen Äußerungen der Schüler als individuellen, kompetenten Teil ihrer Kommunikation deutet. Das gegenseitige Verstehen führt dazu, dass die Bedingungen des Fragilen-X-Syndroms, der Verhaltensphänotyp des Schülers sowie die jeweilige soziale Umgebung, in einen angemessenen Kontext gesetzt werden können. Erst dadurch kann der Schulalltag erfolgreich gestaltet und ein Scheitern des Schülers minimiert werden. / This qualitative research project examines the everyday life of three boys with Fragile X syndrome in their special education classrooms. Fragile X syndrome is the leading inherited cause of intellectual disability and is associated with a specific behavioral phenotype and cognitive and physical characteristics. Utilizing ethnographic participant observation, the specific context in which the Fragile X syndrome becomes “visible” will be analyzed. This context is mainly shaped by the institutional and social conditions on the level of the classroom with its participants (peers and educators). Individuals with Fragile X syndrome need to be viewed not only as living under a genetic condition, but as members of social groups and communities who act in relation to socially and culturally ordered expectations. The understanding of the students’ performative acts as part of their communication abilities can initiate the understanding of the behavioral phenotype within its context. This understanding of Fragile X syndrome as a social category may lead to a successful organization of everyday school life.

This qualitative, phenomenological case study investigated the influence of character education, taught in addition to the Life Skills curriculum, on challenging behaviour in a primary school in Gauteng. Through a filtering process the researcher identified the Youth Citizens’ Action Programme (YCAP) as a suitable additional programme, one which currently includes democratic citizenship and service learning approaches. These are attuned to the study’s theoretical framework, which vests in social and experiential learning, modelling and observation. Although the YCAP at this particular Gauteng school is each year implemented by a team of Grade 7 learners, the implementation of the YCAP involved all the learners across grades. Hence, the empirical study focused on the contribution of the Grade 7 learners to addressing bullying, which learners themselves identified as the most prevalent form of challenging behaviour. The findings showed that the YCAP decreased bullying as challenging behaviour in this particular school. / Inclusive Education / M. Ed. (Inclusive Education)

This study sought to establish the business strategies employed by Mobile Company X Zimbabwe (MCXZ) for it to survive the challenging economy. A qualitative research and a case-based approach involving MCXZ were used. Semi-structured interviews and secondary data were used to produce qualitative data and for triangulation of findings. Data was analysed and managed through qualitative coding and Atlas.ti program. The findings of the study showed that MCXZ employed growth business strategies through market penetration, product development, market development and strategic alliances. In addition, the study found that banking crisis, high competition, rapid technological changes, consumer preferences, shrinking markets and unfavourable government policies are the main threats in the challenging economy. However, MCXZ managed to survive and grow due to the integration of business strategies and the key success factors (KSF) in the industry. The KSF are organisational agility, research and development, quality and affordable mobile phones and effective after sales service and accessories. / Business Management / M. Com.

The dissertation deals with the topic of managing and experiencing stressful (extraordi-nary) situations in teaching in connection with selected teachers' personality traits. The thesis has a theoretical-empirical character. Its theoretical part presents some basic know?ledge related to the topics relevant to the processed issues (teacher's profession, persona?lity, motivation, emotion, workload and stress in the teaching profession context, selected teaching methods and organizational forms, recommendations for effective teaching and learning difficulties solutions, basics of artefacts symbolic interpretation). The aim of the research described in the empirical part of the thesis is to obtain the detailed information about the experience of difficult situations in teaching and the possibilities of their man?agement in connection with the personality structure of the selected teachers. The re?search was carried out in the mixed methods design. His qualitative part contains a multiple? case study (semi-structured interviews were conducted with six lower se?condary school teachers, their teaching was observed, an interview about their thematic collage on the theme Me as a teacher in all its positions and roles was conducted, and the same questionnaires were applied as for the quantitative part of the survey) and some open coded interviews about the thematic collages. In the quantitative research section, the data from four questionnaires were evaluated the orientation questionnaire for detecting stress in teachers by Henning and Keller (1996), the Stress Management Stra?tegies SVF 78 (Janke & Erdmann, 2003), the Freiburg Personality Inventory (Kollárik, Poliaková, & Ritomsky, 1984) and a questionnaire of our own design contains open questions. Most of the participants in the research study experience extraordinary situa?tions in their teaching, which usually cause unpleasant emotions and affect their teaching negatively. Particular relationships between personality characteristics and the teaching of the participants have been found. Respondents did not show a higher level of psychoso?matic disturbance, emotional lability, depressivity or neuroticity compared to the com?mon population. Neither between the level of stress feelings and the age or length of practice, no statistically significant relationship has been found. On the contrary, the male self-description and the adaptive burden management showed a mutually significant con?nection. Also, a higher level of stress impact in physical aspect of women compared to men proved to be statistically significant.

Les litigants sollicitent les centres d’arbitrage pour diriger l’arbitrage dans toutes ses phases afin de donner une garantie supplémentaire qui assure la validité de la sentence arbitrale. Compte tenu du rôle important que les centres d’arbitrage jouent pendant l’instance arbitrale, les litigants mécontents de la sentence arbitrale ou du jugement annulant la sentence tentent d’engager la responsabilité du centre d’arbitrage dès lors qu’il a surveillé, dirigé et participé au rendu de la sentence.De plus en plus la responsabilité des centres d’arbitrage est mise en cause devant les juridictions étatiques différentes, les fonctions et les pouvoirs exercés par les centres d’arbitrage ainsi que le régime de responsabilité leur est applicable font l’objet d’une attention critique de la part de la doctrine dans plusieurs systèmes juridiques. On s’interroge sur l’origine des rapports qui lient les centres d’arbitrage aux autres acteurs de l’arbitrage, sur les obligations et les pouvoirs conférés aux centres d’arbitrage, et sur les fonctions exercées par les centres d’arbitrage pour établir enfin un régime de responsabilité homogène et pertinent à l’égard des fonctions exercées par les centres d’arbitrage qui a une vocation à s’appliquer dans la majorité des systèmes juridiques / Parties to arbitration seek arbitral institutions to administrate their arbitration in order to have an extra guarantee that ensures the validity of the arbitral award. Given the role that arbitral institutions play during the arbitral procedure, parties unsatisfied either by the arbitral award or the annulment of the award tend to claim the liability of arbitral institution for the awards it had supervised, administered and participated in.The more the allegations of liability raise against the arbitral institutions before courts, the more the issue of arbitral institutions’ functions, powers and liability becomes controversial in different jurisdictions. Therefore, the present study tends to clarify the origin of the relationship existing between arbitral institutions and other parties involved in the arbitration at issue, the duties and powers assigned to the arbitral institutions and the functions performed by the arbitral intuitions, which helps eventually in establishing a kind of liability that complies with the functions performed by the arbitral institutions and can be applied in many jurisdictions.

Traditional cameras are most commonly used in visual SLAM to provide visual information about the scene and positional information about the camera motion. However, in the presence of varying illumination and rapid camera movement, the visual quality captured by traditional cameras diminishes. This limits the applicability of visual SLAM in challenging environments such as search and rescue situations. The emerging event camera has been shown to overcome the limitations of the traditional camera with the event camera's superior temporal resolution and wider dynamic range, opening up new areas of applications and research for event-based SLAM. In this thesis, several asynchronous feature detectors and trackers will be used to initialize SLAM using event camera data. To assess the pose estimation accuracy between the different feature detectors and trackers, the initialization performance was evaluated from datasets captured from various environments. Furthermore, two different methods to align corner-events were evaluated on the datasets to assess the difference. Results show that besides some slight variation in the number of accepted initializations, the alignment methods show no overall difference in any metric. Overall highest performance among the event-based trackers for initialization is HASTE with mostly high pose accuracy and a high number of accepted initializations. However, the performance degrades in featureless scenes. CET on the other hand shows mostly lower performance compared to HASTE.

SAMMANFATTNING Bakgrund Elevers grupparbeten utgör en betydande del av HKK-undervisningen. Tidigare forskning kring elevers grupparbeten i allmänhet är omfattande, men forskning gällande elevers grupparbeten inom HKK är ytterst begränsad. Som utpräglat processämne är det av största vikt att eleverna ges möjlighet att träna på praktiska moment inom hem- och konsumentkunskap (HKK), för att eleverna ska kunna utveckla kunskap i handling vilket sedermera ska bedömas av undervisande lärare. Syfte Syftet med studien var att utforska lärares uppfattningar, upplevelser och erfarenheter av grupparbete i HKK. Metod Kvalitativa intervjuer genomfördes med tio HKK-lärare runtom i Sverige. Intervjuerna analyserades med stöd av kvalitativ innehållsanalys. Resultat Det mest framträdande resultatet i studien var att arbetsformen grupparbete var dominerande i såväl praktiskt som teoretiskt arbete inom HKK. Ramfaktorer påverkade, styrde och begränsade undervisningen. Samarbete, kamratlärande, trygghet och praktisk träning var främsta syften med grupparbeten inom HKK. Det sociala klimatet, elevernaskunskapsnivå och särskilda behov var de faktorer som främst togs i beaktning vid sammansättning av elevgrupper. Lärarnas arbete kring elevgruppernas varaktighet skilde sig åt. Observationer var den vanligaste bedömningsformen när elever arbetade i grupp. Bedömning av elever som arbetade i grupp upplevdes vara svårt och utmanande bland lärarna i studien. Slutsats Grupparbete som undervisningsmetod framstår som rådande kutym inom ämnet. Studien påvisade brister med denna undervisningsmetod, främst utifrån bedömningsaspekten. Med mer noggrant uttänkta strategier för varför, hur och när det vore lämpligt att använda grupparbete som undervisningsmetod anser vi att HKK-läraren har möjlighet att höja kvaliteten på såväl undervisning som bedömning. / ABSTRACT  Background Students' group work constitutes a significant part of the teaching in Home and Consumer Studies (HCS). Previous research on students 'group work in general is extensive, but research on students' group work within HCS is extremely limited. As a distinct process subject, it is of the utmost importance that students are given the opportunity to practice practical elements in HCS, so that students can develop ”knowledge in action”, which will be assessed by the teacher.  Objective The aim of the study was to explore the teachers’ perceptions and experiences regarding group work in HCS.  Method Qualitative interviews were conducted with ten teachers in HCS within Sweden. The interviews were analyzed on the basis of content analysis.  Results The most prominent result in the study was that group work was dominant in both practical and theoretical work within HCS. Framework factors influenced, controlled and limited teaching. Cooperation, peer learning, safety and practical training were the main purposes of group work within HCS. The social climate, the students' level of knowledge and special needs were the factors that were mainly taken into account when composing student groups. The teachers' work on the duration of the student groups differed. Observations were the most common form of assessment when students worked in groups. Assessment of students who worked in groups was perceived as difficult and challenging among the teachers in the study.  Conclusion Group work as a teaching method appears to be the prevailing custom within the subject. The study demonstrated shortcomings with this teaching method, mainly based on the assessment aspect. With more carefully thought out strategies for why, how and when it would be appropriate to use group work as a teaching method, we believe that the HCS teacher has the opportunity to raise the quality of both teaching and assessment.
