African drumming as a medium to promote emotional and social well-being of children aged 7 to 12 in residential careFlores, Kim 18 June 2012 (has links)
PAPER COPY ACCOMPANIED BY A DVD OF CHILDREN'S PARTICIPATION IN THE WORKSHOPS. This research project investigated the potential of African drumming to enhance the emotional and social well-being of children in residential care. Sixteen children from the Epworth Children’s Village in South Africa were purposively selected to participate in the study. The majority of participants had been exposed to some form of neglect and/or abuse and displayed high levels of anger, anxiety, depression and/or disruptive behaviour. Mixed in terms of gender and ethnicity, they fell within the middle childhood stage of development. The participants attended weekly sessions of African djembe drumming over a period of four months. Principles and practices of indigenous African music making formed the foundation of the drum circle facilitation approach used. Gestalt theory, as applied in Gestalt play therapy, provided the theoretical framework from which the therapeutic dimensions of African drumming were explored. A mixed methods approach, using both quantitative and qualitative methods of data collection and analysis, was employed. For the quantitative component, participants completed the Beck Youth Inventories, measuring self-concept, anxiety, depression, anger and disruptive behaviour, before and after the project. Concerning the qualitative aspects, focused observations were conducted wherein all video-recorded workshops were regularly and systematically analysed to assess the children’s emotional and social functioning. Furthermore, semi-structured interviews and focus groups were conducted with relevant staff members and children, respectively, in an attempt to explore the value and feasibility of presenting such a programme within the residential care setting. According to the Inventories’ pre- and post-test results, the intervention did not appear to significantly impact upon the participants’ self-concept or levels of depression, anger or disruptive behaviour. Anxiety, on the other hand, increased. Qualitative findings nevertheless suggest that the workshops substantially enhanced the children’s emotional and social functioning, albeit only for the duration of the sessions. The workshops markedly improved participants’ self-esteem and self-confidence, pro-social behaviour, enjoyment, concentration and manifestation of musical capacity (aspects which reflect Gestalt concepts of awareness, contact, self-regulation, self-expression and mastery). Reasons for the failure of these improvements to transfer to the children’s everyday functioning may involve the severity of their socio-emotional difficulties as well as limitations within the drumming intervention itself. / Thesis (DMus)--University of Pretoria, 2012. / Music / unrestricted

Samlingen som arena för barns inflytandeAsadi, Tara, Renström, Ida January 2017 (has links)
Denna kvalitativa studie syftar till att bidra med kunskap kring samlingens utformning samt synliggöra dess konsekvenser för barns inflytande. För att besvara detta har följande frågor varit centrala; hur kan samlingens utformning såsom samlingens innehåll, struktur samt kommunikativa villkor möjliggöra barns inflytande? Vilka konsekvenser får samlingens utformning för barns inflytande? Studien har genomförts genom observationer där vi valt att vara icke-deltagande för att på så vis begränsa vår påverkan så mycket som möjligt.Observationerna genomfördes på en förskola i en åldersblandad grupp med barn 3–5 år där arbetslaget bestod av fyra kvinnliga pedagoger. I den genomförda studien framkommer det att samlingen är starkt styrd av de vuxna och att de är de som bestämmer över samlingens innehåll. Pedagogens val ger konsekvenser för barns inflytande i form av vem som ska få prata, när denne ska få prata samt hur länge. Det framkom att pedagogens val av aktiviteter sätter ramarna för hur pass mycket inflytande barnet kan utöva. En slutsats som kan dras är att barns möjlighet till inflytande under samlingen i många fall är begränsat och villkorat. Studiens resultat är relevant då det öppnar upp för möjligheter till reflektion kring samlingen och dess funktion i förskolan. Vår uppfattning är att samlingen kan fungera som en arena för barns inflytande, vilket vi hoppas kunna få fler att instämma i.

Advanced high frequency switched-mode power supply techniques and applicationsNuttall, Daniel Robert January 2011 (has links)
This Thesis examines the operation and dynamic performance of a single-stage, single-switch power factor corrector, S4 PFC, with an integrated magnetic device, IM. Also detailed isthe development and analysis of a high power light emitting diode, HP LED, power factorcorrection converter and proposed voltage regulation band control approach.The S4 PFC consists of a cascaded discontinuous current mode, DCM, boost stage anda continuous current mode, CCM, forward converter. The S4 PFC achieves a high powerfactor, low input current harmonics and a regulated voltage output, utilising a singleMOSFET. A steady-state analysis of the S4 PFC with the IM is performed, identifying theoperating boundary conditions for the DCM power factor correction stage and the CCMoutput voltage regulation stage. Integrated magnetic analysis focuses on understanding theperformance, operation and generated flux paths within the IM core, ensuring the device doesnot affect the normal operation of the converter power stage. A design method for the S4 PFCwith IM component is developed along with a cost analysis of this approach. Analysis predictsthe performance of the S4 PFC and the IM, and the theoretical work is validated by MATLABand SABER simulations and measurements of a 180 W prototype converter.It is not only the development of new topological approaches that drives theadvancement of power electronic techniques. The recent emergence of HP LEDs has led to aflurry of new application areas for these devices. A DCM buck-boost converter performs thepower factor correction and energy storage, and a cascaded boundary conduction current modebuck converter regulates the current through the LED arrays. To match the useful operatinglifetime of the HP LEDs, electrolytic capacitors are not used in the PFC converter. Analysisexamines the operation and dynamic characteristics of a PFC converter with low capacitiveenergy storage capacity and its implications on the control method. A modified regulationband control approach is proposed to ensure a high power factor, low input current harmonicsand output voltage regulation of the PFC stage. Small signal analysis describes the dynamicperformance of the PFC converter, Circle Criterion is used to determine the loop stability.Theoretical work is validated by SABER and MATLAB simulations and measurements of a180 W prototype street luminaire.

Previous issue date: 2016-08-26 / FACEPE / O círculo arterial cerebral é um polígono anastomótico na base do encéfalo que
comunica o sistema carotídeo com o sistema vértebro-basilar e as carótidas entre si.
Há muitas variações morfológicas nesse polígono e possíveis diferenças entre os
sexos, particularmente no segmento A1 da artéria cerebral anterior e na origem da
artéria cerebral posterior (ACP). O objetivo do presente estudo foi analisar
comparativamente a frequência de hipoplasia do segmento A1 e do padrão fetal da
artéria cerebral posterior no homem e na mulher. Foram analisadas
retrospectivamente 848 angiografias por ressonância magnética arterial, em 426
homens e 422 mulheres, respectivamente, que se submeteram ao exame no Centro
de Diagnóstico Multimagem. Os exames foram escolhidos aleatoriamente entre
1.000 angiorressonância realizadas entre 2010 e 2016, independente do motivo da
solicitação médica. Hipoplasia do segmento A1 foi definido por analise qualitativa,
quando havia uma nítida assimetria entre os dois segmentos A1 direito e esquerdo
bem como o padrão fetal da artéria cerebral posterior. Para análise de hipoplasia
foram medidos os diâmetros dos segmentos A1. Para análise do padrão fetal
(diâmetro da ACP na origem da artéria carótida>diâmetro do segmento P1) foram
analisadas 1.296 artérias carótidas em 648 indivíduos. Na análise estatística utilizouse
o teste exato de Fisher. Os homens 152/326 (46,6%) apresentaram hipoplasia de
A1 em comparação com 108/322 (33,5%) das mulheres (p<0,01, OR=1,7; IC95%
1,3-2,4). A hipoplasia de A1 nos homens foi mais frequente a direita (20% vs. 15%,
p<0,01). O padrão fetal foi mais comum nas mulheres 151/644 (23,4%) do que em
homens, 100/652 (15,3%) (p<0,001, OR=1,7; IC95% 1,3-2,2). As mulheres também
apresentam mais padrão fetal bilateral do que os homens (8,0% vs. 3,4%; p<0,01;
OR=0,4; IC 0,2-0,8). A hipoplasia do segmento A1 da artéria cerebral anterior é mais
frequente nos homens e nas mulheres há uma maior frequência do padrão fetal da
artéria cerebral posterior. / The Circle of Willis is an anastomotic polygon encephalon base that communicates
the carotid system with vertebrobasilar system and carotid each other. There are lots
of morphological variations that polygon and possible differences between genders
particularly in the A1 segment of the anterior cerebral artery and the origin of the
posterior cerebral artery (PCA) which are risk factors for anatomical brain aneurysms.
The purpose of this study was to comparatively analyze the frequency of hypoplasia
of the segment A1 and fetal type of cerebral posterior artery in man and woman. It
was retrospectively reviewed 648 magnetic resonance angiographies in 326 men and
322 women, respectively. The tests were randomly chosen among about a thousand
magnetic resonance angiographic performed between 2010 and 2016 in Multimagem
Diagnostic Center, regardless of the medical reason request. Hypoplasia of the A1
segment was defined by qualitative analysis, when there was a clear asymmetry
between the two segments A1, right and left. For hypoplasia analysis were also
measured diameters of segments A1. For hypoplasia analysis were also measured
diameters of segments A1. For analysis of the fetal type (diameter of the ACP origin
of the carotid artery> diameter of the P1 segment of the ACP) were analyzed 1,296
carotid arteries (right and left) in 648 individuals. Statistical analysis was performed
using Fisher's exact test. In men 152/326 (46.6%) showed hypoplasia A1 compared
to 108/322 (33.5%) of women (p <0.01, OR = 1.7; 95% CI, 1.3-2, 4). Hypoplasia A1
was more common in men right (20% vs. 15%, p <0.01). Fetal type was more
common in women 151/644 (23.4%) than in men (100/652; 15.3%) (p <0.001, OR =
1.7; 95% CI, 1.3-2, two). Women also have more bilateral fetal rate than men (8.0%
vs. 3.4%; p <0.01). In conclusion, hypoplasia of the A1 segment of the anterior
cerebral artery is more common in men and in women there is a greater frequency of
fetal type of the posterior cerebral artery.

O círculo operário católico em Sergipe : práticas educativas e organização da cultura operária (1935-1969). / CATHOLIC WORKER IN THE CIRCLE SERGIPE: educational practices and organization of working class culture (1935-1969).Santos, Gilvan Vitor dos 14 December 2011 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This dissertation intends to analyze educational practices and the organization of working class culture, with emphasis on educational and cultural circle of the Catholic Worker of
Sergipe, in the period 1935 to 1969. The Circle of Sergipe Catholic Worker is part of the process of romanization developed from the year 1910 in the diocese of Aracaju that will be reflected in the middle was proletarian in 1935. The study includes the experience of training Catholic worker, construction worker of the Catholic model. Aiming to show how did the experience of Catholic education in Sergipe proletariat from the role of the Catholic Worker Circle of Sergipe, using several sources: institutional and official documents, photographs, papers and studies related to the theme. For this, we used the categories of analysis of Norbert
Elias - civilization; Roger Chartieu representations, among others. We seek to understand the political and social participation of workers under the auspices of the Catholic Church which stood in opposition to communism as a form of political awakening towards the organization of workers in Sergipe, since this action of the Catholic Church, in the middle proletarian Sergipe consolidates a new form of social participation, where Catholics and communists started fighting separately to organize workers in unions or associations. / Esta dissertação tenciona analisar as práticas educativas e a organização da cultura operária, com ênfase nas ações educativas e culturais do Círculo Operário Católico de Sergipe, no período de 1935 a 1969. O Círculo Operário Católico de Sergipe é parte do processo de romanização desenvolvido a partir do ano de 1910 na diocese de Aracaju que foi será refletido no meio proletário a partir de 1935. O estudo contempla a experiência da formação operária católica, construtora do modelo católico de trabalhador. Objetivando mostrar como aconteceu a experiência de formação católica no proletariado sergipano a partir do protagonismo do
Círculo Operário Católico de Sergipe, utilizando varias fontes: documentos oficiais e institucionais, fotografias, jornais e estudos relacionados a temática. Para isso, recorreu-se as
categorias de análises de Norbert Elias civilização; representações de Roger Chartieu, entre outros. Busca-se, compreender a participação política e social dos trabalhadores sob os auspícios da Igreja Católica que se mantinha em oposição ao comunismo, como forma de um despertar político rumo à organização dos trabalhadores sergipanos, já que essa ação da Igreja Católica, dentro do meio proletário sergipano consolida uma nova forma de participação social, onde Católicos e comunistas passaram a lutar separadamente para organizar os trabalhadores em entidades sindicais ou associações.

The effect of the circle of security parenting programme on parental self-efficacy and internalising behaviours in childrenRose, Jenny Lee January 2019 (has links)
Philosophiae Doctor - PhD / Early Childhood development is an important phase of development, wherein the trajectory of
the child’s life can potentially be determined. However, not all children experience positive
outcomes, and many present with psychopathology. In particular, psychopathology in children
will manifest as either externalizing behaviours or internalising behaviours. The treatment of
internalising disorders becomes increasingly complex, as there isn’t always outward behaviour
to give evidence to the inward difficulties. Literature amplifies the importance of the role of
the parent in ensuring the well-being of the child and in working towards healthy
developmental outcomes.

The benefits of using world literature for globalizing English in the ESL classroom / Fördelarna med att använda världslitteratur för att globalisera engelska i andraspråksundervisningZeino, Arwa, Tabiei, Aiat January 2021 (has links)
Although the focus on English as a global language is apparent in the Swedish curriculum today, many educators do not take advantage of world literature and non-native English authors in their ESL classrooms. With the help of empirical research, we investigate the benefits of using such literature for gaining global awareness. Furthermore, we analyze the activities and teaching approaches used in the empirical studies. Through this essay, we summarize the empirical research used for this essay and synthesize the results to find out what implications were found. It shows that using non-native fiction helps students to learn and explore different cultures, which also expands their global view. Apart from this, teaching methods such as discussions, literature circles, presentations, blogging and collaborative learning deepened students' global view and cultural awareness. The teaching methods that were used while working with world literature showed that students were conscious of their own learning and developed this ability by working in a social environment. This paper concludes with describing the limitations of writing the study, and presents a future research project that involves the field of world literature.
