The diploma thesis deals the phenomenon of education of Roma children in the system of special elementary education. The aim of the thesis is to capture the specifics of this education focusing on the analysis of the civic education on primary practical schools in context of relationships to Roma pupils. The theoretical part is focused on the current situation of the Roma minority in the Czech republic. The work briefly describes the history of the Roma minority and the current situation of Roma people in the modern society. Most attention is paid to the Czech primary educational system, especially teaching Roma pupils on practical primary schools. The work briefly deals with the current changes in the educational system, so called inclusive education too. The practical part is focused on the methodology of the multicultural education themes, on the second degree of an elementary practical school in Vimperk.

The first definitive haematopoietic stem cells (HSCs) produced during embryonic development are generated from a specialised subset of endothelial cells known as haemogenic endothelium. Recently, it was reported that Gata3 plays a dual role in the development of sympathetic nervous system and haematopoietic system. In fact, Gata3 has proven to be crucial for the production of HSCs through regulation of catecholamine production from the co-developing sympathetic nervous system. Also, it was recently shown that Gata3 is expressed in the haemogenic endothelium and haematopoietic progenitor cells. Here, I will specifically examine the role of Gata3 in the production of HSCs; if it is expressed and plays a role in the precursors from which HSCs arise. Using a Gata3-GFP reporter mouse line, we found that Gata3 is expressed in various cell types in the HSCs microenvironment, including mesenchymal cells, endothelial cells, haematopoietic cells and sympathetic nervous system, and this expression was stage dependant. In the endothelial cells, we have found that the haemogenic endothelium activity is enriched in Gata3 expressing cells. Within the haematopoietic cells, we have found that Gata3 marks a specific stage along the developmental pathway towards the generation of definitive haematopoietic stem cells, and that Gata3 expressing haematopoietic cells are enriched for the most immature and stem cell like progenitors. Moreover, Gata3 will be specifically knocked out in haemogenic endothelial cells to determine whether it plays an essential role in the production of HSCs from the endothelium using the Vec-Cre system. We found that Gata3 within the haemogenic endothelium plays a major role in haematopoietic progenitors formation, and possibly haematopoietic stem cell formation. Finally, we used molecular assay (RNA seq) to identify the role of Gata3 in the haematopoietic stem cell microenvironment and found that Gata3 plays a major role in the development and differentiation of various cells and systems, and implicated Gata3 as cell cycle regulator. In summary, we found that Gata3 expressing cells is enriched for haemogenic endothelium, crucial for the haematopoietic progenitors formation, plays and important role in endothelial to haematopoietic transition, and plays a key developmental role in both haematopoietic stem cell and its microenvironment.

Children today encounter the English language on a wide scale, even outside the school walls. As they are exposed to various forms of English language input, they inevitably pick up a certain level of proficiency, which they can later use on their own. This study aims to more precisely research through which mediums English learners in primary school worldwide tend to encounter English the most, as well as how engaging in English activities outside the classroom might affect their English proficiency. By studying prior research on the subject through content analysis, it was found that, while there are some regional differences in terms of prevalence, children mainly encounter English through television, music, and computer games. It was also found that many children who had never before received any English training still possessed a level of English proficiency. These findings shed light on the importance of input for language acquisition as well as how children’s extramural interests can be of importance in the classroom setting.

Magister Psychologiae - MPsych / This study examined three schools; namely a Public, Ex model C, and a Youth juvenile rehabilitation school. A non-experimental survey design was used for this study. The sample consisted of 47 educators across the three types of schools. Data was collected by means of two instruments: a demographic questionnaire, and the Maslach Burnout Inventory (MBI) consisting of three subscales namely; Emotional Exhaustion, Depersonalization, and Diminished Personal Accomplishment. It was hypothesised that due to the stressful nature of work in disadvantaged and resource lacking schools, as well as the unstable and unsafe environment in certain schools, burnout among educators in Public and Youth juvenile rehabilitation schools will have a higher prevalence rate than educators in Ex model C schools. The study also aimed to identify which various educator demographic variables correlate with high burnout levels. Correlational results of the study found no significant relationships between the three subscales of the MBI and certain educator demographic variables across the three types of schools. The results of an Analysis of Variance (ANOVA) test revealed a borderline non-significant difference in the Emotional Exhaustion subscale between the Youth juvenile rehabilitation school and Public schools. Post Hoc comparison tests suggested Public school educators in the sample had the highest levels of burnout in terms of Emotional Exhaustion across the three types of schools, while educators in the Youth juvenile rehabilitation schools showed the lowest levels of burnout in terms of Emotional exhaustion. The results of the present study were discussed from the perspective of the Conservation of Resources theory, suggesting resource depletion as a central facet to burnout and how prolonged stress leads to burnout. Future qualitative studies exploring the etiology of burnout was thus recommended. / South Africa

This thesis deals with the development of a client-server application for Red Hat company. Client participates in testing process of JBoss platform and gets user-defined performance data which sends during testing to the server application by platform independent communication. The server application allows to analyze the received data which can be also compared by several perspectives. These services for data analysis and comparison are accessible for server users using the web client. The server application supports the import of the performance data stored in the XML file and also their export for qVue portal. The client part of the application is implemented in Java and the server application is based on Java EE platform.

Important changes that have taken place within South African politics mean that most companies today are under pressure to implement affirmative action (AA) policies within their organisations (equity policies). These AA policies include employment equity (EE) policies and Black economic empowerment (BEE) policies. Company agendas now include aspects such as equality and social justice and organisations will continue to be evaluated in terms of how well they meet employment equity targets. Many employees and citizens in general view the process and implementation of these policies with great scepticism and even reluctance. It is important to understand and examine these perceptions because employee perceptions influence employee attitudes and behaviour and therefore have an effect on the success (or failure) of an organisation. The effective implementation of EE and BEE policies will to a large extent depend on whether or not these policies fit into the overall culture of an organisation or whether the organisational culture is adapted to accommodate these policies. Previously, corporate cultures largely ignored principles of diversity and difference. It is important that the question of whether this has changed or changed to a large enough degree be answered, especially with regard to the implementation of EE and BEE policies. Some EE and BEE programmes may fail because previous structures, cultural systems and management styles are adhered to without adapting these to suit the needs of these policies. Ultimately, employees’ perceptions of AA in their organisation, namely the EE and BEE policies that are implemented, influence the attitudes and behaviour of employees and ultimately the success of the organisation. These perceptions are related to the culture of the organisation. This study explores employee perceptions of equity policies, specifically EE and BEE, in terms of differences in demographic characteristics, including race, gender, age, years’ service and occupational level; as well as relative to the main factors of these equity policies, as confirmed by a factor analysis performed on the data, namely the importance, impact and clarity of these policies. The sample company’s organisational culture is also explored in terms of these equity policies and perceptions thereof. The ultimate goal of this research is to examine if any relationships exist between the implementation of organisational cultural practices in an organisation relative to equity policies and employee perceptions of these, and if any relationships do exist, to determine the nature of such relationships. The sample size in this study is 476 employees. / Dissertation (MA)--University of Pretoria, 2010. / Psychology / unrestricted

In this work we studied magnetic properties of molecular magnets of the new heteropolyanion {Cu20}, dodecanuclear cluster {Ni12}, and the heterometallic {Cr7M} wheels, in which one of the CrIII ions of Cr8 has been replaced by a Fe, Cu, Zn, Ni, ion with this extra-spin acts as local probe for the spin dynamics.Such systems have been synthesized recently and they are well described using the Heisenberg spin Hamiltonian with a Zeeman term of an applied magnetic field along the z-axis. Using the numerical exact diagonalization method, we have calculated the energy spectrum and the eigenstates for different compounds,and we have used them for reexamining the available experimental susceptibility data to determine the values of exchange parameters.We have studied the thermodynamic properties such magnetization, susceptibility, heat-capacity. At low temperature regions molecular magnets act as individual quantum nanomagnets and can display super-paramagnetic phenomena like macroscopic quantum tunneling, ground state degeneracy, level-crossing. A crucial issue for understanding these phenomena is the coupling between magnetic molecular levels and the environment such as nuclear spins. We have modeled the behavior of the proton spin lattice relaxation rate as a function of applied magnetic field for low temperatures as it is measured in Nuclear Magnetic Resonance (NMR) experiments.

The emphasis of this study is focusing on three-dimensional (3D) investigations of the manganese sulfide (MnS) inclusions characteristics in steels by using electrolytic extraction (EE). Two steel grades, 42CrMo4 and 157C, heat treated (HT) at 900 oC were investigated. 42CrMo4 steel samples were heat treated for 5, 10, 15 and 30 minutes while 157C steel samples were heat treated for 5 minutes. Samples of 42CrMo4 were taken from middle zone of an as-cast steel bar while that for grade 157C were taken from 3 different zones (centre, middle and surface). Inclusions were collected on film filters and analyzed by SEM for classification and determination of their characteristics including the size, number density (Nv), morphology and composition. The aspect ratio (AR) as well as particle size distribution (PSD) were also compared for steel samples conducted at various HT times. The result showed that EE is a reliable method of investigation inclusion characteristics. The inclusions were classified into 3 types according to their morphology and composition. Type I was elongated rod-like MnS, type II was coarsened sheet-like MnS and type III was spherical MnS inclusions. In addition, HT significantly reduced the Nv and fairly reduced AR but no significant reduction in size observed. The peak of PSD decreased with an increased HT time. The change of Nv, length, AR and PSD could be altered because of uneven inclusion distribution in filter and different sampling positions.
