Entwicklung zerebraler Läsionen in der MRT nach akuter Ischämie im definierten kurzfristigen Verlauf unter konservativer TherapieEisenhauer, Jasmin 08 May 2017 (has links) (PDF)
Beim akuten ischämischen Schlaganfall ist die Größe der initialen DWI-Läsion (Diffusions-gewichtete Sequenz) in der zerebralen MRT zur Abschätzung der Prognose des Patienten umstritten. Die Beobachtung des Verlaufs der DWI-Läsion in den ersten Tagen nach einem Schlaganfall scheint hierfür besser geeignet. Hierbei zeigt sich, dass ein Infarktwachstum eher mit einem schlechteren klinischen Ergebnis korreliert. Ein mögliches Infarktwachstum vorherzusagen ist deshalb von großem Interesse. Bei nicht-lakunären Infarkten, die durch Verschlüsse größerer Arterien verursacht werden, ist die Ausbreitung des Infarktkerns in zuvor minderperfundierte Areale (d.h. in die Penumbra), als Ursache eines Wachstums anerkannt. Die Penumbra wird als die Differenz zwischen DWI- und PWI-Läsionen (Perfusions-gewichtete Sequenz) angesehen, was als PWI/DWI-Mismatch bezeichnet wird. Unklar ist, ob dieses Mismatch-Konzept auch auf lakunäre Ischämien (DWI-Läsionen < 2 cm Ø) angewandt werden kann. Ziel dieser prospektiven Studie war, den Zusammenhang zwischen dem initialen DWI/PWI-Mismatch und der Infarktentwicklung im kurzfristigen Verlauf bei 100 konservativ behandelten Patienten zu untersuchen. Das Patientenkollektiv war hinsichtlich der Infarktsubtypen (lakunäre und nicht-lakunäre) als inhomogen einzustufen. Am Tag der Aufnahme und an Tag 7 wurden anhand eines MRT-Schlaganfallprotokolls die Volumina der DWI und PWI-Läsionen, die Mismatch-Volumina, das Infarktwachstum, das relative Mismatch und das relative Infarktwachstum untersucht. Das Infarktwachstum zeigte einen engen Zusammenhang mit dem initialen DWI/PWI-Mismatch. Dies traf vor allem dann zu, wenn man die relativen Werte betrachtete. Hieraus ergibt sich, dass ein großes initiales Mismatch ein späteres Infarktwachstum wahrscheinlicher macht. Für die Zukunft könnte man daher davon ausgehen, dass das relative Mismatch, bezogen auf die relative Infarktentwicklung, einen besseren prognostischen Wert aufweist, als die absoluten Werte.

Challenging the Traditional Student Leadership Paradigm: A Critical Examination of the Perceptions of Students of Color at Predominately White InstitutionKerrigan, Michele Brown January 2016 (has links)
Thesis advisor: Ana M. Martinez-Aleman / This qualitative study employed a Critical Race Theory (CRT) lens to gather a deeper understanding the racialized experiences of students of color (SOC) at a PWI, and how these experiences impact the way in which they understand, conceptualize, and/or actualize student leadership on campus. This study presents the lived experiences of twenty-five SOC. Participants shared their experiences and perceptions through individual semi-structured interviews, with an opportunity to also participate in a focus group. Findings revealed that the ways in which participants view how race is socially constructed on campus and their encounters with normalized racism (such as their experiences with microaggressions, the lack of diversity, the negative racial climate, and the racial segregation on campus) seemed to profoundly impact participants lived experiences and perceptions. Participants in this study exhibited a strong pull towards SOC groups (both for participation and leadership expression), citing a desire to seek involvement with individuals of similar/racial and ethnic background, a responsibility to give back to their racial/ethnic group, and seeking a group that affirmed their sense of identity as some of the top reasons they joined SOC groups. However, participants’ perceptions of predominately White groups on campus, encounters with normalized racism, and the way they view student groups are valued (or undervalued) on campus seems to suggest that the campus racial climate may play a powerful role in students’ decision making around co-curricular involvement and leadership expression. The findings strongly intimate that the college campus remains a microcosm of larger society in that it continues to perpetuate normalized racism as a product of inherent (and biased structures), influencing students’ leadership perceptions and expression. This study recommends that institutions assess the racial landscape on campus in terms of perceived and actualized student leadership, be willing to engage in experimentation on different practices that will foster a greater sense of inclusivity within student leadership, and take active steps towards creating permanent inclusive change. / Thesis (PhD) — Boston College, 2016. / Submitted to: Boston College.

Dark on Campus: A Phenomenological Study of Being a Dark-Skinned Black College StudentLee, Kiara 01 January 2019 (has links)
As recent research finally starts to recognize colorism, a form of discrimination where light skin is valued over dark skin within an ethnic group, as a legitimate form of discrimination in the Black community, research on colorism in higher education still wanes. A limited amount of scholarship focuses on the manifestation of colorism in education and even less research examines the implications of complexion on Black college students and their intersectional identities. As empirical studies describe how complexion often denotes institutional degradation for dark-skinned Black students in K-12 and beyond -- from teacher perceptions, to the school-to-prison pipeline, to social dynamics with peers and more, this study privileges the voices of these marginalized students. This qualitative study uses phenomenology to detail the experiences of dark-skinned Black college students at a PWI (predominately white institution) to illustrate their lived experiences, the often intricate relationships between dark skin and intersectional identities like gender and ethnicity, and the unique phenomenon of being dark-skinned on campus. This work aims to complicate, adding rigorous research and thick qualitative description to burgeoning scholarship on colorism in education.

Adolescents’ well-being in Kathmandu, Nepal : A study based on mindmaps and questionnairesKällerteg, Sandra, Ahlinder, Lovisa January 2014 (has links)
Aim: Our goal with this study was to see the well-being index among adolescents in Kathmandu, Nepal. But also to investigate the factors that contribute to well-being and what the adolescents believe is the most important thing. Method: The method used in this study was a questionnaire, it included eight questions with 44 adolescents participating. Group interviews were used by help with mindmap, groups of 3-4 adolescents to investigate their perspective of well-being used. We chose to do both because we wanted the results of the index and the adolescents thoughts about well-being to emerge. Results: The results from the questionnaire showed that 34,1 percent among the adolescents have 80-90% well-being according to the PWI scale we applied. According to the adolescents’ own estimated level of well-being, about 68 percent of them have good well-being and 30 percent of them have a really good well-being. However the PWI scale shows that only 9 percent have a really good well-being. The results of the group interviews showed the most important thing for well-being according to the adolescents are satisfaction, quality of life, happiness, love (friends, family, relationship), education, health and social service.

Factors that Influence Under-represented Minority Students in Science, Technology, Engineering, and Mathematics attending a Predominately White Institution, the Role of RetentionWhite, Vemitra Mornit 07 May 2016 (has links)
The quality of STEM in higher education is widely recognized as an important issue. There is tremendous amount of concern around persistence, retention, and attrition for under-represented minority students (URMs) majoring in STEM disciplines. Retaining this population of students in the different STEM discipline is also a major concern for educators and policy makers in the United States. Student interest is there, however, problems arise when course work becomes challenging. As a result, students tend to lose confidence and change their majors. The purpose of this study was to discover factors that are related to persistence in STEM majors for a group of URMs who participated in a summer bridge program between 2008- 2014 at a Predominately White Institution of higher learning. In this study the researcher used archived data and quantitative research methods to identify different factors. Data analysis was conducted to answer the eight research questions that guided the study. To answer research question 1, descriptive statistics were used to analyze data that provided a comprehensive description of the students’ high school and college academic performance. One way ANOVAs were computed to analyze data for research questions 2-6, whereas Chi –Square Tests of Independence were used to analyze data for research questions 7 and 8. The researcher examined data for 232 URMs who participated in a summer bridge program during 2008-2014 academic years. The findings for research question 1 revealed that URMs represented in this study were college ready according to their average ACT scores and high school GPAs. An examination of two gatekeeper courses (Calculus and Chemistry) revealed that majority of the students passed with a letter grade of C or below. The findings for research questions 2-6 revealed statistically significant differences for URM students who persisted in STEM majors. They included ACT composite scores, ACT subscale scores all expect for reading, first semester GPA, first year GPA, sophomore year GPA, and number of credits earned through sophomore year. The findings for research questions 7 and 8 revealed that persistence was not influenced by gender or STEM major.

Relação das crianças do sul do Brasil com o ambiente e seu impacto no bem-estar pessoalGalli, Francielli January 2014 (has links)
Esta dissertação tem como objetivos verificar as propriedades psicométricas da Escala de Atitudes Ambientais para Crianças (EAAC; adaptada de Leeming, Dwyer, Porter & Bracker, 1995) e da Escala Infantil de Satisfação com o Ambiente (EISA; criada pelo Grupo de Pesquisa em Psicologia Comunitária); verificar a associação entre bem-estar pessoal (mensurado através da Personal Wellbeing Index) e variáveis ambientais e analisar as atitudes ambientais das crianças da amostra. Foram realizados três estudos, com 1746 crianças (53,5% meninas) com idades entre 8 e 13 anos (M = 10.17; DP = 1.492) residentes de Porto Alegre (54.9%) e do interior do Rio Grande do Sul (45.1%). Os resultados do primeiro estudo indicaram que os instrumentos analisados, EAAC e EISA, apresentam bons índices de ajuste para a amostra pesquisada quando da realização na análise fatorial (exploratória e confirmatória). Com relação ao segundo estudo, as análises de regressão multivariadas indicaram que o PWI é explicado pelos itens da EAAC em 11.5% e pelos itens da EISA em 14.4%. Estão associoados ao bem-estar pessoal: a satisfação com o ambiente residencial e escolar, as atitudes ambientais que envolvem a família, o contato com a natureza e o contato com animais. O terceiro estudo buscou verificar se existem diferenças entre grupos para as atitudes ambientais e os resultados indicaram que as crianças que estudam em escolas públicas, assim como as crianças que vivem em cidades do interior e as crianças mais novas, tendem a desenvolver mais atitudes favoráveis ao ambiente. Em uma etapa qualitativa do terceiro estudo, as crianças mencionaram preocupar-se com a crise ambiental e apresentaram atitudes ambientais voltadas a ações cotidianas e de ativismo. / This dissertation aims to evaluate the psychometric properties of the Children’s Environmental Attitudes Scale (EACC; adjusted from Leeming, Dwyer, Porter & Bracker, 1995) and of the Children’s Environment Satisfaction Scale (EISA; developed by the Grupo de Pesquisa em Psicologia Comunitária); to verify the association between personal wellbeing (measured by the Personal Wellbeing Index School Children) and environmental variables; and to analyze the environmental attitudes of the children in the sample. There were conducted three studies with 1746 children (53.5% girls) aged between 8 and 13 years old (M = 10.17; SE = 1.492) residents on Porto Alegre (54%) and on inner cities of Rio Grande do Sul State (45.1%). The results of the first study indicated that EAAC and EISA scales had good overall fit rates when exploratory and confirmatory factorial analyses were performed. In the second study, multivariate regression analysis showed that the Personal Wellbeing Index is predicted in 11.5% by the EACC items and in 14.4% by the EISA. The personal wellbeing is associated to: satisfaction with school and residence environment; family environmental attitudes; contact with animals and contact with nature. The third study aimed to check if there are differences of environmental attitudes between the groups. Outcomes indicated that children of public schools, children of inner cities and younger children tend to develop more favorable environmental attitudes. During the qualitative stage of the third study, children mentioned that they worry about the environmental crisis and presented environmental attitudes related to daily actions and activism behaviors.
