Thesis (MEdPsych)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This research journey explores the lived experiences of children who had previously been living on the street and were now part of a house being managed by two voluntary organisations. The caregivers and boys are incorporated as co-researchers in a participatory action research journey within a post-modern, social constructivist paradigm. The following research curiosities inform the study: • How do the caregivers and children in the house stand up to homelessness and poverty? • How do their stories reflect the notion of doing hope? Positioning myself within the research journey necessitates the discussion of beliefs and constructs that inform the paradigm, such as post-modernism, social constructionism, discourses and the deconstruction of discourses. According to Denzin and Lincoln (1994:14), the research strategy comprises the practical application of the assumptions underlying the paradigm through the use of certain skills, and can be regarded as the paradigm in action which provides the methods for the researcher to engage in the research journey. In this study, a qualitative method is used to describe and understand human behaviour and the meaning attached to it in the participant's own terms. The coresearchers participate during all the aspects of the research journey, and the cyclical nature of participatory action research described by Babbie and Mouton (2001:315- 316) is honoured. The narrative approach is used in conducting the conversations. According to White (1991:28), it is a non-recriminatory, power-sharing way of interaction that provides a context where the consciousness and knowledges of the person are at the centre of the process of consultation. An opportunity is created for the boys and caregivers to story their experiences and to explore the meanings that they attach to these experiences. The main ethical principles that operate are autonomy, nonmaleficence, beneficence and validity. Tape-recordings, transcriptions, reflections and letters are used to document the research journey. Homelessness and poverty had been dictating certain behaviours to the boys, and it was even dictating their lived identities. At the time of the research journey, the caregivers are creating a community of support that is effectively doing hope for the boys, thus enabling them to loosen the grip of poverty and homelessness. Personal reflections indicate that I as researcher am not unaffected by the research journey. Although obstacles present themselves during the research journey, new possibilities are opened up for further exploration. / AFRIKAANSE OPSOMMING: Hierdie navorsingsreis ondersoek die ervarings van kinders wat voorheen op straat gewoon het en wie nou in 'n huis woon wat deur twee vrywillige organisasies bestuur word. Die versorgers en seuns word betrek as medenavorsers in 'n deelnemende aksienavorsingsreis binne die raamwerk van 'n postmodernistiese, sosiaal konstruktivistiese paradigma. Die studie word toegelig deur die volgende navorsings-ondersoeke: • Hoe weerstaan die versorgers en kinders in die huis die impak van woningloosheid en armoede? • Hoe reflekteer die stories wat hulle vertel die idee van 'hoop doen'? Ten einde myself binne die navorsingsreis te posisioneer noodsaak 'n bespreking van die oortuigings en samestellings onderliggend aan die paradigma, soos postmodernisme, sosiaal konstruktivisme, diskoerse en die dekonstruksie van diskoerse. Volgens Denzen en Lincoln (1994:14) behels die navorsingsstrategie die praktiese uitvoering van die opvattings onderliggend aan die paradigma deur die toepassing van sekere vaardighede. Die navorsingsstrategie kan beskou word as die paradigma in aksie deurdat dit die metodes vir die navorser verskaf om betrokke te raak by die navorsingsreis. 'n Kwalitatiewe metode word tydens hierdie studie gebruik om menslike gedrag te beskryf en te verstaan en om vas te stel watter betekenis die deelnemers self aan hulle belewenisse heg. Die medenavorsers neem deel aan alle aspekte van die navorsingsreis en die sikliese aard van deelnemende aksienavorsing soos beskryf deur Babbie en Mouton (2001:315-316) word gerespekteer. 'n Narratiewe benadering word tydens die gesprekke gebruik. Volgens White (1991:28) is die narratiewe benadering nie-blamerend en is daar 'n gelyke verdeling van mag. 'n Konteks word geskep waar die bewustelikhede en kennisse van die persoon sentraal geplaas word in die konsultasieproses. 'n Geleentheid word geskep vir die seuns en versorgers om hulle ervarings te vertel en om die betekenisse wat hulle aan die ervarings heg te eksploreer. Hoofsaaklik word outonomie, niekwaadwilligheid, goedgesindheid en geldigheid as etiese beginsels gerespekteer. Bandopnames, transkriberings, refleksies en briewe word gebruik om die navorsingsreis te dokumenteer. Woningloosheid en armoede het vantevore die gedrag van die seuns, sowel as die identiteite wat hulle uitgeleef het, voorgeskryf. Ten tye van die navorsingsreis is die versorgers besig om 'n gemeenskap van ondersteuning te skep wat effektief hoop doen vir die seuns en wat hulle in staat stel om die greep van woningloosheid en armoede te verbreek. Persoonlike refleksies dui aan dat ek as navorser nie onaangeraak gelaat word deur die navorsingsreis nie. Struikelblokke verskyn tydens die navorsingsreis, maar nuwe moontlikhede baan die weg vir verdere eksplorasie.

The diploma thesis, which is called Building of the State amd national culture in Carpathian Ruthenia, deals mainly with federal activities in the east of the Republic. It focuses mainly on the operation of Czech teachers and their contribution to creating the new state . The work is divided into five chapters.The first expands on the influence of teachers on the development of the national idea of single state of newly annexed Ruthenia. The second part describes the activities of the Czechoslovak organizations that were created since 1919. The third section describes the activities of such organizations that were not focused on the national idea, but were created solely for the joy of their members. The fourth chapter describes the Ruthenian societies as a counterweight to those of Czechoslovakia, also including examples of their way of thinking. The last section lists additional organizations, which were based on Ruthenia, but it did not prove to be important within the whole concept of this work.

Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. Characterisation of mechanical properties is necessary for the formulation of a numerical model to design an improved support structure. The ship was impregnated with polyethylene glycol (PEG) for dimensional stabilisation. All elastic engineering constants of the Vasa oak have been identified and compared with those of recent oak by means of the static and dynamic testing. The experiments were done on samples with cubic geometry, which allowed obtaining all elastic constants from a single sample. The usage of cubic samples with orthotropic mechanical properties during compressive experiments was validated with finite-element simulations. The Young's moduli of the Vasa oak in all orthotropic directions were smaller than those for the recent oak. The shear moduli of Vasa oak was determined and verified with the resonant ultrasound spectroscopy. The time-dependent mechanical behaviour of the Vasa oak has been studied. Creep studies were performed in uniaxial compression on the cubic samples in all orthotropic directions. The samples loaded in the longitudinal direction were subjected to different stress levels. A stress level below 15% of the yield stress in the longitudinal direction did not result in non-linear creep with increasing creep rates within the time frame of the tests. The results of the studies in radial and tangential directions showed that creep was dominated by the effect of annual fluctuations in relative humidity and temperature. The weight changes based on annual fluctuations of relative humidity were measured for Vasa oak and recent oak. The Vasa oak showed higher variations due to an increased hygroscopicity which is the result of the impregnation with PEG. In conceiving a full-scale finite-element model of Vasa ship, not only the stress-strain relations of the material but also those of the structural joints are needed. Since the in-situ measurement of joints is not an option, a replica of a section of the ship hull was built and tested mechanically. The load-induced displacements were measured using 3D laser scanning which proved to have advantages to conventional point displacement measurements. The mechanical characteristics of the Vasa oak and joint information presented in this work can be used as input for a finite-element model of the Vasa ship for simulation of static and time-dependent behaviour on a larger scale. / Stötta Vasa

No. of bitstreams: 1 Tese Lidiane.pdf: 1449534 bytes, checksum: 483272938ee77a60ad54caa8f898d243 (MD5) Previous issue date: 2017-08-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Introduction: acute bronchiolitis (AB) is an inflammatory disease of the airways considered the most common pathology of the lower respiratory tract in childhood. Responsible for a large number of hospitalizations in infants is one of the leading respiratory diseases worldwide, raising the costs of health care in infants. According to epidemiological data, between 75,000 and 125,000 children are hospitalized in the United States each year with infections caused by respiratory syncytial virus (RSV), accounting for approximately 25% of pediatric pneumonia and up to 70% of hospitalizations for acute bronchiolitis. Children with deficiencies in cell-mediated immunity can develop more severe and prolonged infections. Activation of the mTOR, STAT-3 and STAT-6 signaling pathways have been identified as key regulators in different functions of the immune system. The aim of this study was to investigate the relationship between the gene expression of mTOR, STAT-3, STAT-6 and AB severity. Methods: it is a cohort study that included a group of infants less than 12 months old with AB admitted to a tertiary hospital in Porto Alegre, Brazil. Nasopharyngeal lavage was collected from all patients and stored in Trizol solution at -80?C at the Biomedical Research Institute (IPB) of PUCRS for subsequent extraction of RNA and cDNA synthesis. Specific primers were used to verify the relative expression of mTOR, STAT-3 and STAT-6 by means of real-time PCR. The results obtained were correlated with AB severity markers such as hospitalization time and wheezing time. Results: for the analysis of expression of the mTOR signaling protein and transcription factors STAT-3 and STAT-6, 23 patients hospitalized with AB were included. A general correlation was made between clinical markers (days of hospitalization and days of wheezing) and expression of signaling pathways. Data were stratified according to severity markers and showed a trend towards decreased mTOR expression in patients with a wheezing time equal to or greater than 5 days (r = -0.702 and p = 0.024). However, the STAT-3 and STAT-6 signaling pathways were not correlated with AB severity factors when applied in this group of patients. Conclusion: transcription factors are essential for generating effective immune responses. mTOR, STAT-3 and STAT-6 participate in the expression of a variety of genes in response to cellular stimuli and may play a key role in the manifestation of the disease. Our data demonstrate the decrease in mTOR expression, with improvement in clinical markers of severity, but other studies are needed to reinforce this finding. / Introdu??o: a bronquiolite aguda (BA) ? uma doen?a inflamat?ria das vias a?reas considerada a patologia mais comum do trato respirat?rio inferior na inf?ncia. Respons?vel por um grande n?mero de hospitaliza??es em lactentes ? uma das principais doen?as respirat?rias em todo o mundo, elevando os custos de cuidados de sa?de em lactentes. Segundo dados epidemiol?gicos, entre 75.000 e 125.000 crian?as s?o hospitalizadas nos Estados Unidos anualmente com infec??es causadas pelo v?rus sincicial respirat?rio (VSR), respondendo por aproximadamente 25% das pneumonias pedi?tricas e at? 70% das interna??es por bronquiolite aguda (BA). As crian?as com defici?ncia na imunidade mediada por c?lulas podem desenvolver infec??es mais graves e prolongadas. A ativa??o das vias de sinaliza??o mTOR, STAT-3 e STAT-6 t?m sido identificadas como reguladores-chave em diferentes fun??es do sistema imune. O objetivo deste estudo foi investigar a rela??o entre a express?o g?nica de mTOR, STAT-3, STAT-6 e a gravidade da BA. M?todos: trata-se de um estudo de coorte onde foi inclu?do um grupo de lactentes de idade inferior a 12 meses, com BA, internados em um hospital terci?rio de Porto Alegre, Brasil. Foi coletado lavado nasofar?ngeo de todos os pacientes e armazenados em solu??o de Trizol ? temperatura de -80?C no Instituto de Pesquisas Biom?dicas (IPB) da PUCRS para posterior extra??o de RNA e s?ntese de cDNA. Foram utilizados os iniciadores espec?ficos para verificar a express?o relativa de mTOR, STAT-3 e STAT-6 por meio de PCR em tempo real. Os resultados obtidos foram correlacionados com marcadores de gravidade da BA como tempo de interna??o e tempo de sibil?ncia. Resultados: para a an?lise da express?o da prote?na de sinaliza??o mTOR e fatores de transcri??o STAT-3 e STAT-6, foram inclu?dos 23 pacientes hospitalizados com BA. Foi realizada uma correla??o geral entre os marcadores cl?nicos (dias de interna??o e dias de sibil?ncia) e a express?o das vias de sinaliza??o. Os dados foram estratificados de acordo com os marcadores de severidade e mostraram uma tend?ncia para a diminui??o da express?o de mTOR em pacientes com tempo de sibil?ncia igual ou superior a 5 dias (r = -0,702 e p = 0,024). No entanto, as vias de sinaliza??o STAT-3 e STAT-6 n?o foram correlacionadas com fatores de gravidade da BA quando aplicadas neste grupo de pacientes. Conclus?o: os fatores de transcri??o s?o essenciais para gerar respostas imunes eficazes. O mTOR, STAT-3 e STAT-6 participam na express?o de uma variedade de genes em resposta a est?mulos celulares e podem desempenhar um papel-chave na manifesta??o da doen?a. Nossos dados demonstram a diminui??o da express?o de mTOR, com melhora dos marcadores cl?nicos de gravidade, por?m outros estudos s?o necess?rios para refor?ar este achado.

This is a qualitative, descriptive and exploratory research conducted in basic health units of the eight administration districts of Porto Alegre. Data were collected through semi-structured interviews, in which13 health professionals and 16 pregnant women participated. The results were analysed through the thematic content analysis, using the Atlas ti software. The research unfolded in two empirical studies that constituted the body of this dissertation. The first study describes the evaluation that the primary health care professionals perform during the implementation of the rapid HIV and syphilis tests in the Stork Network, in the city of Porto Alegre, RS. In this study, the key results were lack of assumption in respect to the health system polices, lack of infrastructure of the health services, discontinuity of the capacitation and matrix support, the test demand, difficulty of the health care professionals to speak about sexuality and sexual practices, counselling as an essential instrument during the performance of the rapid test, the importance of the participation of the partners during the prenatal care, the rapid HIV testing, and the use of condom. The second study covers the perception of the pregnant women, who are users of the primary health care, about the rapid HIV and syphilis tests, and about the counselling received in the Stork Network, in the city Porto Alegre, RS. The main results of this study observed from the speeches of the pregnant women are the importance of the health professional in explaining the users of the service about the reliability of the test and the counselling. In addition, the analysis of the interviews showed that some pregnant women received counselling and provided positive value about it, while others did not receive the counselling. Furthermore, some women pointed out that the counselling seemed to be restricted only to the pre-test. Power mechanisms of the health professionals that compromise the autonomy of women could be observed from the speeches of the pregnant women. In relation to the use of condoms, confidence in the partner was another factor that appeared to be associated with the non-use of condoms. Condom use during the gestational period also appeared linked to an idea of greater care with the baby, over the care of the mother. In conclusion, the importance of dialogue between professionals and users and the participation of partners in prenatal care could be observed through the speeches of the pregnant women. / Esta disserta??o teve como objetivo geral compreender como os profissionais que atuam na Aten??o Prim?ria em Sa?de e as gestantes avaliam a implanta??o do Teste R?pido de HIV e S?filis na Rede Cegonha, em Porto Alegre/RS. Tratou-se de uma pesquisa qualitativa, descritiva e explorat?ria realizada nas unidades b?sicas de sa?de das oito ger?ncias distritais de Porto Alegre. A coleta de dados foi realizada mediante entrevistas semiestruturadas, nas quais participaram 13 profissionais e 16 gestantes. Os resultados foram analisados a partir da an?lise de conte?do tem?tica, utilizando o software Atlas ti. Esta pesquisa se desdobrou em dois estudos emp?ricos que constituem o corpo da disserta??o. O primeiro estudo se focalizou na avalia??o que os profissionais da aten??o prim?ria em sa?de fazem sobre a implanta??o do Teste R?pido de HIV e S?filis na Rede Cegonha, no munic?pio de Porto Alegre/RS. Nesse estudo se destacaram como principais resultados a falta de apropria??o em rela??o ? pol?tica, a falta de infraestrutura dos servi?os, a descontinuidade das capacita??es e matriciamento, a solicita??o do teste, a dificuldade dos profissionais falarem sobre sexualidade ou pr?ticas sexuais, o aconselhamento como um imprescind?vel instrumento na realiza??o do teste r?pido, a import?ncia da participa??o dos parceiros no pr?-natal e na realiza??o do Teste R?pido de HIV e o uso do preservativo. O segundo estudo avaliou a percep??o que as gestantes usu?rias da aten??o prim?ria em sa?de fazem sobre o Teste R?pido de HIV e S?filis e o aconselhamento na Rede Cegonha, no munic?pio de Porto Alegre/RS. Os principais resultados deste estudo se deram a partir dos discursos que destacaram a import?ncia de o profissional esclarecer aos usu?rios a confiabilidade da t?cnica de teste r?pido e aconselhamento. A an?lise das entrevistas, tamb?m, mostrou que algumas entrevistadas receberam o aconselhamento e valoram-no de forma positiva, enquanto outras n?o o receberam. Al?m disso, algumas apontaram que o aconselhamento parecia estar restrito somente ao pr?-teste. A partir das falas das gestantes, p?de-se observar mecanismos de poder pelos profissionais que comprometem a autonomia das mulheres. Em rela??o ao uso do preservativo, a confian?a no parceiro foi outro fator que apareceu associado ao seu n?o utilizo. O uso do preservativo no per?odo gestacional, tamb?m, foi associado a uma ideia de cuidado maior com o beb?, em detrimento ao cuidado com a pr?pria sa?de. Para concluir, nas falas, revelou-se a import?ncia do di?logo entre profissionais e usu?rias e a participa??o dos parceiros no pr?-natal.

Worldwide research regarding the movement patterns, heart rate recordings and work–to–rest ratios of rugby union referees is very limited. It is therefore very important to extend research regarding this topic. The first objective of this dissertation was to determine the frequency, duration and intensity of movement patterns and work–to–rest ratio of different refereeing panels of South African Rugby Union referees during match–refereeing at the National Club Rugby Championship in Stellenbosch during 2007. The second objective was to compare the two halves of the match with regard to the frequency, duration and intensity of the different movement patterns and the work–to–rest ratios of various of SARU referees during match–refereeing at the National Club Rugby Championship in Stellenbosch during 2007. The South African Rugby Union referees were monitored during match–refereeing by means of video and heart rate recordings for a total of 16 matches within a week tournament. The frequency and duration of the different movement patterns during both halves of the matches were analysed using a Dartfish TeamPro analysis software package. Heart rates were recorded during the matches to determine the movement pattern intensities of the referees for the duration of each match using a Suunto Team pack heart rate monitoring system. The work–to–rest ratios were determined by comparing the time (in seconds) spent working (lateral movements and sprinting) to the time spent resting (standing still, walking and jogging). The results revealed a moderate practical significant difference (d=0.51) between the mean frequency of jogging movement patterns for the different refereeing panels. A moderate practical significant difference was also found between the mean duration of jogging (d=0.43) and sprinting (d=0.43) movement patterns of different refereeing panels. The mean intensity of the movement patterns by the different refereeing panels showed large practical significant differences between the anaerobic threshold (d=3.68) and sub–threshold (d=1.36) levels and a moderate practical significant difference for the maximal heart rate zones (d=0.43). Both the provincial and contender panel referees had work–to–rest ratios of 1:4 during match–refereeing. In comparing the two halves of rugby match–refereeing, a large practical significant difference was found between the mean frequency of movement pattern values for standing still (d=2.53), walking (d=2.50), jogging (d=2.42), lateral movements (d=2.86) and sprinting (d=1.31) as well as for mean duration of movement pattern values for standing still (d=2.05), lateral movements (d=0.76) and sprinting (d=0.77). Large practical significant difference were found between the time spent in the maximal threshold (d=2.07), anaerobic threshold (d=0.92) and sub–threshold (d=7.90) heart rate zones measured during the two halves of match–refereeing. Average work–to–rest ratios of 1:3.5 and 1:5 were found for the first and second halves of rugby match–refereeing, respectively. The information gained regarding the activity profile of SARU referees could be used to determine the influence of rugby refereeing experience on the movement patterns and work–to–rest ratio of rugby referees. It can also provide information for constructing specific training programmes and drills in the development of rugby match–required fitness standards for referees. A key component of a rugby union referee’s game is positioning. Being in the right place at the right time is vital. The results of this study suggest that movements associated with positioning ? namely standing still, walking and lateral movements are the major components of the game of referees’ movement during match–refereeing. However, further research is required on this topic of research. / Thesis (M.A. (Sport Science))--North-West University, Potchefstroom Campus, 2012.

However, further research is required on this topic of research. / Thesis (M.A. (Sport Science))--North-West University, Potchefstroom Campus, 2012.
