Background: As overnutrition rises along with nutrition transition in low- and middle-income settings such as Bangladesh, evaluating metabolic risk factors using overnutrition measures in adolescents is important. Before doing such evaluation, a preliminary step should be taken to attest the independence of overnutrition measures from total height. Moreover, sitting height measures are recognized as important metabolic risk indicators. This study aims to understand the association of attained height –total and sitting– with overnutrition measures including body mass index (BMI), percent body fat (PBF), fat mass index (FMI) and fat free mass index (FFMI) and to assess modification by sex. Methods: Cross-sectional analysis of the MINIMat study’s 15-year follow-up data from October 2017 to December 2018 was undertaken. The associations of attained height –total and sitting– with each of the overnutrition measures were analysed using multiple linear regressions. Results: Overnutrition measures were non-independent of total height among male adolescents. The taller they were, the higher their BMI would be. This increase of BMI along with the height would have been contributed relatively more by the increase of fat free mass (FFM) than that of fat mass (FM). When total heights of both sexes were kept equal at the median, female adolescents had lower lean mass (FFMI) and higher fat mass (FMI) than the males although there was no difference in BMI on average between them. Sitting height was associated with all overnutrition measures with varying extents depending on the sex. Conclusion: When assessing overnutrition measures, it is important to examine beyond BMI and into FMI and FFMI. Again, when assessing the metabolic risks using overnutrition measures among adolescents, normalizing those indices for height is important to be considered to avoid inferring the implication from growth as risks.

The diploma thesis deals with the issue of immigration and its impact on the economy in Australia, Great Britain and the United States of America. In the introduction, various migration theories explaining the migration motifs and immigration policies, whose specifics and the type of requirements of the monitored countries sheds the composition of incoming individuals, are discussed. This profile is complemented by the analysis itself, which examines the socio-economic factors of foreign-born population living in the monitored countries. This analysis is carried out by cross-sectional data comparisons, but it monitors the arrival times of individuals, providing an overview within the timeline. In order to determine the impact of immigration on employment and average wages, regression was used, but this effect was in no way proven beyond the impact on average wages in Australia.

Introduction Research show that both educational attainment and genetic propensity to education (PGSEdu) can be associated with geographic mobility and that individuals living in more deprived areas tend to have poorer health while those living in more advantaged places tend to have better health. In this thesis, the aim was to study how polygenic scores for education and attained education influence and differ by geographic mobility, and how they influence the association between geographic mobility and mortality. Methods Data was retrieved from the Swedish Twin Registry with twins born 1926-1955 (n=14,211). Logistic regression models were performed to test if PGSEdu and attained education predicted geographic mobility. Cox regression models were then performed to test if geographic mobility, attained education or PGSEdu decreased the risk of mortality. Results The results show that both the PGSEdu and attained education predicted geographic mobility, in both independent and joint models, with higher education indicating a higher mobility. Geographic mobility decreased the risk of mortality in the independent model, but joint models showed that the association was completely explained by attained education.  Conclusions To conclude, both PGSEdu and attained education influenced geographic mobility. Moreover, attained education explained the relationship between geographic mobility and mortality.

LEIPERTOVÁ, G. (2012): Interdisciplinary relation between cartography and mathematics in the teaching at high school. Department of Social Geography and Regional Development, Charles University in Prague. The present diploma thesis analyses interdisciplinary relations between cartography and mathematics on three levels: on the level of intended curriculum, on the level of implemented curriculum and on the level of attained curriculum. On the level of the intended curriculum, project documents such as the Framework Educational Programme for High Schools and the School Educational Programmes of selected high schools are especially studied. The content analysis of selected textbooks of geography evaluates relations between cartography and mathematics on the basis of occurrence and (quality of) explication of required subject matters, amount of examples, illustrations and charts. Moreover, selected chapters of cartography, in which mathematical skills are applied, are elaborated in detail. On the level of the implemented curriculum, the real state of teaching of these interdisciplinary relations at selected high schools is evaluated through questionnaires for teachers of geography and of mathematics. On the level of the attained curriculum, the ability of pupils to combine knowledge of cartography and...

Vikten av utbildning och livslångt lärande är betydelsefulla faktorer för att den ekonomiska tillväxten i vårt land ska stimuleras, för att välfärden ska kunna tryggas och för att motverka ytterligare samhällsklyftor. Statistik från Skolverket visar på en konstant andel, ca 10 % de senaste fem åren, av elever i årskurs 9 som inte är behöriga att söka till gymnasiet. Det beror på att de inte har uppnått kursplanemålen för att få godkänt i kärnämnena svenska, matematik och engelska. Detta är bakgrunden till att vi har valt att redogöra för och belysa lärares utsagor och resonemang kring hinder och förutsättningar för elevers måluppfyllelse i kärnämnena. I denna kvalitativa studie har vi använt oss av intervjuer som teknik. Vi har intervjuat sex lärare, på fem olika skolor i en mellanstor kommun i sydvästra Sverige. Studien är uppdelad på tre nivåer, organisations-, grupp- och individnivå. På organisationsnivå handlar det bland annat om skolpolitik, skolans ledning och skolans styrdokument. På gruppnivå handlar det om klassen/gruppen och arbetslaget och på individnivå handlar det om den enskilde eleven och den enskilde läraren. Resultatet indikerar på att lärarnas resonemang till stor del kom att kretsa kring lärarens egen roll för elevers måluppfyllelse. Ytterligare framkom det att styrdokumenten spelar en betydande roll, på grund av att de lämnar stort tolkningsutrymme. Andra faktorer som resultatet visar på är att elever inte är tillräckligt motiverade för skolarbete och därigenom måluppfyllelse. Det finns elever som har låg begåvning och det finns elever med utländsk bakgrund som kommer in sent i det svenska skolsystemet. De kan därför få svårigheter att uppnå målen. Vår slutsats är därför; nej skolans mål är inte möjliga att nå för alla elever! / The importance of education and lifelong learning are essential factors to ensure and stimulate economic growth in our country, to secure welfare and counteract polarisation of social classes. During the last five years statistics from the Swedish Board of Education shows a constant number of approximately 10 % of the students in year 9 who have not qualified for upper secondary education. This is because they have not attained the goals of the syllabus which require a pass in the core subjects of Swedish, mathematics and English. This fact is the reason for our investigation in which we illustrate teachers’ assertions and lines of arguments concerning impediments and preconditions for attaining the goals of the core subjects. In this qualitative study we have used interviews as our main approach. We have interviewed six teachers at five different schools in a medium size municipality in the south-west of Sweden. The study is divided into three levels, organization, group and individual level. On the organization level the key issues are school policy, school administration and the steering documents of the school. On the group level the key issues are the class/group and the working team and on the individual level the study focuses on the individual pupil/student and the individual teacher. The result indicates that the teachers’ lines of arguments were focused on his/her own role of importance for the pupils’/students’ attainments of the goals. Furthermore it appeared that the steering documents play an important part because they can be interpreted in many ways. Other factors shown in the study are that pupils/students are not motivated enough to do schoolwork and thereby reach the goals. There are pupils/students who are less talented and others who have a different cultural background and get enrolled in the Swedish school system late. They might therefore have difficulties attaining the goals. Thus our conclusion is; no it is not possible for every pupil/student to attain the goals of school! We use both the words pupil and student because we sometimes mean the younger children (pupils) but also the older ones (students).

The purpose of this research was to trace the first year of progress made towards implementing the new curriculum for basic education in Mozambique and to gain clarity about the process with a view to formulating pertinent recommendations for its successful implementation. This study starts by presenting background information which highlights the need for the curriculum to be more relevant to the sociopolitical changes in Mozambique as the main aim of transforming the basic education curriculum. Secondly, it maps out the national environment in which the new curriculum is operating and the critical factors justifying the changes brought by curriculum transformation. Then it introduces the research questions that essentially explore four issues, namely (1) the nature of the new curriculum and the strategy used to implement it, (2) the perceptions of educators, subject specialists and principals regarding the new curriculum, (3) classroom practices as envisaged in the new education curriculum and (4) efforts towards successful implementation of the new curriculum. Before the research topic is addressed the precepts of curriculum theory and the principles of curriculum development are discussed as the context within which to conceptualize the implementation of the new curriculum in Mozambique. The study under review explores the seven basic conditions for effective change identified by Giacquinta (1998). The researcher has found with due reference to the subject literature that the relevance of these conditions is borne out by the findings of the research under review. This research therefore has the merit that it relates these conditions (referred as factors in the study) to each other, thus serving as an important guide for monitoring and implementing education change of which curriculum reform is a basic element. The study employed mainly quantitative analysis (descriptive statistical analysis and factor analysis) having as research instrument a survey questionnaire designed to gauge educators’ and learners’ opinions regarding implementation of the new Basic Education Curriculum in Mozambican schools. As the main findings of the study, it was clear from participating principals’ and teachers’ responses that school leadership is an essential factor in assuring the presence and maintenance of all the necessary conditions for successful implementation of the new curriculum. The capacity building is another indispensable factor derived from participating principals’ and teachers’ responses concerning successful implementation of the new curriculum, which is viewed as an important condition for creating and maintaining teachers’ confidence in their ability to fulfil new role expectations. In this regard, principals and teachers identified innovative classroom practices as an important condition for successful implementation of the new curriculum. So, principals’ responses showed that it was important to recognise the association between leadership, innovative classroom practices and capacity building, while participating teachers’ responses showed that there was an important link between capacity building and leadership, rewarding and innovative classroom practices. Thus, with the exception of rewarding the same factors were identified as critical by both principals and teachers. A distinct enabling condition for successful implementation of the new curriculum that emerged from participating students’ responses comprised (1) an association of students’ expectations, learning opportunities and outcomes, (2) students’ subject preferences, (3) and a friendly and supportive school environment. This research both contributes to understanding of the curriculum implementation process, and enables the formulation of pertinent recommendations towards successful curriculum implementation. It also enriches the current literature on this matter through critical analysis of a new curriculum implementation, offering empirical evidences of the relevance of school resocialization, which entails restructuring and reculturing. / Thesis (PhD)--University of Pretoria, 2008. / Education Management and Policy Studies / unrestricted

The study intends to investigate the nature and cognitive demands of contextual word-problems posed in the FET mathematics examinations of IEB and NSC. The analysis of the mathematization of real-life situations to form contextual word-problems is based on the theory of authentic task situations. The theoretical basis for analyzing mathematics teaching and learning is the Realistic Mathematics Education (RME) theory. Data was obtained using the schedule of mathematization of real-life situations and the schedule of total marks of contextual word-problems and national performance. All contextual word-problems included in the 2008-2013 question papers of IEB and NSC mathematics examinations were analysed. The research revealed that 509 marks out of 1800 marks were allocated to contextual word-problems in IEB examinations; whereas 473 marks out of 1800 marks were allocated to contextual word-problems in NSC examinations. / Mathematics Education / M.

Uma nova capacidade para a transmissão de informação clássica através de canais quânticos é proposta. A capacidade erro-zero de canais quânticos (CEZQ) é definida como sendo a máxima quantidade de informação por uso do canal que pode ser enviada através de um canal quântico ruidoso, considerando uma probabilidade de erro igual a zero. O protocolo de comunicação restringe palavras-código a produtos tensoriais de estados quânticos de entrada, enquanto que medições coletivas entre várias saídas do canal são permitidas. Portanto, o protocolo empregado é similar ao protocolo de Holevo-Schumacher-Westmoreland. O problema de encontrar a CEZQ é reformulado usando elementos da teoria de grafos. Esta definição equivalente é usada para demonstrar propriedades de famílias de estados quânticos e medições que atingem a CEZQ. É mostrado que a capacidade de um canal quântico num espaço de Hilbert de dimensão d pode sempre ser alcançada usando famílias compostas de, no máximo,d estados puros. Com relação às medições, demonstra-se que medições coletivas de von Neumann são necessárias e suficientes para alcançar a capacidade. É discutido se a CEZQ é uma generalização não trivial da capacidade erro-zero clássica. O termo não trivial refere-se a existência de canais quânticos para os quais a CEZQ só pode ser alcançada através de famílias de estados quânticos não-ortogonais e usando códigos de comprimento maior ou igual a dois. É investigada a CEZQ de alguns canais quânticos. É mostrado que o problema de calcular a CEZQ de canais clássicos-quânticos é puramente clássico. Em particular, é exibido um canal quântico para o qual conjectura-se que a CEZQ só pode ser alcançada usando uma família de estados quânticos não-ortogonais. Se a conjectura é verdadeira, é possível calcular o valor exato da capacidade e construir um código de bloco quântico que alcança a capacidade. Finalmente, é demonstrado que a CEZQ é limitada superiormente pela capacidade de Holevo-Schumacher-Westmoreland.
