Adjustment issues and their effect on international undergraduate students : a case study in Ghana

Anatsui, Denise Veronica 03 1900 (has links)
The phenomenon of students traversing the globe in search of higher education has increased over the past decade. They travel from every region of the world to institutions of higher learning - to colleges and universities - that accept them. Altogether, countries in Africa welcome thousands of students into their various colleges and universities. Ghana, where this study is based, boasts of well over 140 state-run and privately - run universities. Over the past two decades, these institutions have experienced significant increases in their admission numbers in their international student population. Some of the research on the academic experiences of international undergraduate students shows that they do not perform well during their first years on campus and that they experience what is defined as adjustment issues. The thesis research uncovers and examines adjustment issues experienced by international students (between ages 17-29) pursuing undergraduate degrees at a small, co-educational, private university college (XUC) in Ghana. Located within Ghana’s capital city, Accra, this four-year college annually admits thirty to forty international students and accommodates nearly three thousand students who are at various stages of their study. During the academic year 2017-2018, the college had enrolled 126 international students. In this study, the researcher focuses on the effect of adjustment issues on the academic performance of international students. The researcher posits that there is a correlation between adjustment levels and Grade Point Averages (GPAs). Therefore, international students who have high adjustment levels to student life and life at XUC, Ghana experience average to high Grade Point averages. Conversely, international students who experience low adjustment levels to student life and life in XUC, also experience low Grade Point Averages. / Educational Management and Leadership / Ph. D.

Este trabalho analisa as políticas de EJA desenvolvidas pela União e pelo Estado de São Paulo, no período 2003-2009, sob a ótica do regime de colaboração em um Estado federativo. Elegemos como instâncias a serem objeto de nossa análise a Diretoria de Políticas de Educação de Jovens e Adultos da Secretaria de Educação Continuada, Diversidade e Alfabetização do Ministério da Educação DPEJA/SECAD/MEC, e a Secretaria de Estado da Educação de São Paulo SEESP. Através da descrição e análise de políticas e programas, e dos dados de demanda e oferta escolar por essas duas instâncias, buscamos avaliar como o regime de colaboração, entre as esferas federal e estadual de governo, tem se concretizado no Estado de São Paulo, no sentido e garantir a efetivação do direito à educação das pessoas jovens e adultas que não puderam iniciar ou concluir a escolarização básica na idade considerada regular. A pesquisa foi realizada mediante análise de documentos, realização de entrevistas com pessoas envolvidas com a temática e revisão da bibliografia sobre o tema. Conclui-se que a as responsabilidades estabelecidas pela legislação referente à obrigatoriedade da oferta de EJA não tem sido respeitada pela União e pelo Estado de São Paulo. Um dos principais fatores ligados a este descumprimento da legislação é o fato de que a colaboração entre estes dois entes federados em relação à EJA não se efetivou satisfatoriamente no período analisado. / educational policy; youth and adult education; federalism; São Paulo (State)

Programa de Pós-Graduação em Geociências-Geoquímica. Niterói, RJ / Os hidrocarbonetos presentes no ambiente consistem em misturas complexas de compostos derivados de múltiplas fontes. Os combustíveis fósseis representam a principal contribuição, devido à taxa e escala espacial, em que o petróleo tem sido usado como fonte de energia e matéria-prima para a indústria química. O objetivo deste estudo foi avaliar os níveis de concentração e identificar fontes de hidrocarbonetos na Bacia do Alto Iguaçu e, em especial, na área de influência da Refinaria Presidente Getúlio Vargas (REPAR). Além dos fatores de poluição crônica, a área de estudo foi alvo de um derrame acidental de petróleo em julho de 2000. Diversos indicadores em diferentes compartimentos ambientais (água superficial, sedimento, solo e água subterrânea) foram avaliados na fase pós-derrame e no monitoramento ambiental ao longo de várias campanhas por mais de uma década. Os esforços de avaliação foram concentrados nos seguintes indicadores: os nalcanos, os alcanos isoprenoides, os hidrocarbonetos policíclicos aromáticos (HPA), os biomarcadores de petróleo e ainda o total de hidrocarbonetos de petróleo (THP). Os resultados identificaram como principal aporte de matéria orgânica para as águas superficiais dos rios Barigüi e Iguaçu, os fluxos materiais originados em região a montante do acidente, refletindo a contribuição antropogênica crônica da cidade de Curitiba. Em 2007 e 2008, as concentrações de THP e HPA nas águas superficiais e sedimentos dos rios Barigüi e Iguaçu refletem uma expressiva melhoria nas condições desses rios em relação a 2000. Na área interna da refinaria (Ponto Zero), observou-se uma nítida diminuição (atenuação) natural das concentrações de THP no solo em todas as profundidades dos perfis amostrados ao longo do tempo nos Banhados 1 e 4 e, em particular, uma diminuição importante das concentrações entre 2004 e 2007. Para a identificação das fontes de hidrocarbonetos foram utilizadas razões diagnósticas e quimiometria. As razões diagnósticas calculadas a partir de concentrações de HPA sugeriram que, na maioria dos sedimentos dos Rios Barigüi e Iguaçu coletados nas campanhas de 2000 e 2001, a fonte petrogênica é a principal. Somente na estação a montante do acidente no Rio Barigüi, a fonte pirolítica predominou nestas duas campanhas. As razões diagnósticas que apresentaram maior eficiência na identificação de fontes de hidrocarbonetos nos sedimentos dos rios Barigüi e Iguaçu foram: ΣC1-Fenantrenos/Fenantreno; e (ΣHPA parentais de 3-6 anéis)/(Σ5 séries de HPA alquilados). A identificação de fontes através de razões diagnósticas calculadas a partir de áreas e alturas de picos cromatográficos demonstrou sua aplicabilidade verificando a relação entre os compostos encontrados em amostras de solo da área interna da refinaria com a amostra de petróleo derramado no acidente, após quase uma década da ocorrência do vazamento. A identificação de fontes através método de quimiométrico baseado na análise de componentes principais (ACP) de seções pré-processadas e combinadas dos Cromatogramas de Íons Selecionados (CIS) mostrou que as amostras mais contaminadas estão na área interna da refinaria. Essas amostras apresentam um padrão de distribuição petrogênica e diferentes graus de intemperismo. As amostras da área externa à refinaria (Guajuvira, General Lúcio e Balsa Nova) são menos ou não contaminadas e/ou contém uma mistura de contribuições diagenéticas, pirolíticas e petrogênicas onde predominam diferentes proporções. Os locais mais distantes da atividade industrial (Balsa Nova) contem, como esperado, os níveis mais baixos de contaminação por HPA. Os resultados de biomarcadores demonstraram que não há evidências para concluir que as amostras da área externa à refinaria e o óleo Cusiana vazado tenham a mesma origem. Os resultados ao longo dos rios Barigüi e Iguaçu e do Ponto Zero demonstraram que as ações de emergência para a contenção do óleo foram adequadas para os rios, e que a contaminação decorrente do derrame ficou predominantemente contida no Ponto Zero e diminuiu significativamente após uma década. / Hydrocarbons present in the environment consist of complex mixtures of compounds derived from multiple sources. The main contribution lies on fossil fuel inputs due to the rate and spatial scale by which petroleum has been used as an energy source and chemical feedstock. The aim of this study was to assess the concentration levels and identify sources of hydrocarbons in the Upper Iguaçu Watershed and, in particular, in the area of influence of the President Getulio Vargas Refinery (REPAR). In addition to the factors of chronic pollution, the study area was the scenario of an acute accidental oil spill in July 2000. Numerous indicators in different environmental compartments (surface water, sediment, soil and groundwater) were assessed in the post spill phase and during the environmental monitoring programs over the course of several campaigns for more than a decade. Assessment efforts were concentrated on the following indicators: n-alkanes, alkanes isoprenoids, polycyclic aromatic hydrocarbons (PAH), petroleum biomarkers and total petroleum hydrocarbons (TPH). The results identified as the main contribution of organic matter to surface waters of the Barigüi and Iguaçu Rivers the materials flows originated in the region upstream of the accident, reflecting chronic anthropogenic contribution of the city of Curitiba. In 2007 and 2008, the TPH and PAH concentrations in surface waters and sediments of the Barigüi and Iguaçu Rivers revealed a significant improvement in the conditions of these rivers when compared with 2000. Inside the refinery area (Point Zero), it was observed a clear natural decrease (attenuation) of the concentrations of TPH in the soil at all depths sampled over time in Marshes 1 and 4 and, in particular, an important decrease of concentrations between 2004 and 2007. Diagnostic ratios and chemometrics were used to identity hydrocarbon sources. The diagnostic ratios calculated from the concentrations of PAH suggested that, in the majority of sediments from the Barigüi and Iguaçu Rivers collected in 2000 and 2001 campaigns, the main source is petrogenic. Only in the station upstream the accident in the Barigüi River, the pyrolytic source predominated in these two campaigns. The diagnostic ratios that presented higher efficiency in identifying sources of hydrocarbons in sediments of the Barigüi and Iguaçu Rivers were: ΣC1- Phenantrenes/Phenanthrene; and (Σ3-6 rings parental PAH)/(Σ5 alkylated PAH series). The source identification through diagnostic ratios calculated from heights and areas of chromatographic peaks demonstrated its applicability establishing a relationship between the compounds found in soil samples of the internal area of the refinery and the sample of the oil spilled in the accident, after nearly a decade of occurrence of the spillage. The source identification through chemometric method based on principal components analysis (PCA) of preprocessed and combined sections of Selected Ion Chromatograms (SIC) showed that the most contaminated samples are inside the refinery area. These samples present a petrogenic pattern and different weathering degrees. Samples from outside the refinery area (Guajuvira, General Lúcio e Balsa Nova) are either less or not contaminated, and/or contain mixtures of diagenetic, pyrogenic and petrogenic inputs where different proportions predominate. The locations farthest away from industrial activity (Balsa Nova) contain, as expected, the lowest levels of PAH contamination. The biomarkers results do not show any evidences to conclude positive matches between the samples from outside the refinery area and the spilled Cusiana oil. The results along Barigüi and Iguaçu rivers and Point Zero demonstrated that emergency actions to contain the oil were appropriate for the rivers, and that the contamination resulting from the spill was mostly contained in the Point Zero and decreased significantly after one decade

Genderová analýza vnímání prvotního hříchu, z pohledu vybraného vzorku věřících, české komunity z Rumunska / Gender analysis of the perception of original sin from the perspective of a sample of believers in the Czech community from Romania

Pekárková Schneiderová, Eliška January 2014 (has links)
In my thesis I deal with a biblical "myth" of the original sin and with a question how this topic can demonstrate the genesis of gender duality in a sense of superiority and inferiority using the authors catholic and feminist theology and subsequent data collection. The topic of the original sin is being analysed from a gender view -first in the theoretical part of the thesis that has helped me to continue to the following part of a research. The research consists of semi-structured interviews with a group of people belonging to a specific community. These people were born in the Czech villages in Romania and live nowadays in the Czech Republic. The original sin and its "myth" are still being presented at the level of a myth. His consequences remain in the background of the society and public attention. That is why I decided to deal with this topic. In this way I connect my own interest with this group, which includes a minority of a society with special characteristics. The aim of this thesis is to present the consequences of the original sin on a theoretical level and in terms of research, which I also contribute to with my interviews. And so to answer the research question regarding the influence of minority companies mostly from the standpoint of faith.

Circadian blood pressure within young adults in Viet Nam : An exploratory study comparing a normal blood pressure group and a prehypertension group

Zahirovic, Rezak, Ekman, Scott January 2015 (has links)
Hypertension is a global disease that many effected people in developing countries is not aware of. Hypertension is linked with cardiovascular disease. Prehypertension is not a disease but if not correctly treated, it could develop into hypertension. The aim of the study was to investigate if there are any differences in circadian blood pressure between two study groups, one group with normal blood pressure and one group with prehypertension. This study was a explorative study and its design is based on measurements of blood pressure values and a questionnaire was used to help get the data collection. 51 students volunteered to have their blood pressure taken from them and out of these 51, 24 where selected into two groups of 12 each for the Ambulatory blood pressure monitoring. hese 24 students would be a part of our study and an ambulatory (Schiller-102 plus) blood pressure monitor was used to collect the data. The prevalence of prehypertension findings in the clinical testing phase was 37% of the population. There was a variation between the groups during the day (systolic) but there was not a significant difference during the night.

Analýza výskytu vybraných zoonóz v Jihočeském kraji / Analysis of occurrences of selected zoonoses in South Bohemian region

SOUMAROVÁ, Michaela January 2015 (has links)
This diploma thesis is focused on the evaluation of six selected zoonoses with the occurrence in South Bohemia (campylobacteriosis, salmonellosis, listeriosis, tick-borne meningoencephalitis, Lyme borreliosis, tularemia) between the years 2003-2013. Campylobacteriosis and salmonellosis were evaluated the most common zoonoses in the South Bohemian Region during the monitored period. Their common feature is the alimentary transmission. Between 2003 to 2008 salmonellosis recorded the highest number of reported cases, on the contrary, campylobacteriosis has reported the highest number of occurrences since 2008. District of Czech Budweis showed the highest incidence of both zoonoses during the monitored period (4,139 cases of salmonellosis and 4,924 cases of campylobacteriosis). Another but not less important zoonotic is tick-borne meningoencephalitis, which incidence had the highest number in South Bohemian Region of all the regions of Czech Republic. The second part of the thesis is based on questionnaire studies focused on awareness of zoonoses and the issue of resistance and overuse of antibiotics. In total 479 questionnaires were evaluated. The survey findings may be equally described as interesting and positive, since the respondents had considerable awareness of the issue of antibiotic resistance.
