The teaching of astrobiology to develop competent thinking skills in non-science major college students

Oliveira, Carlos Fernando Carvalhido 20 November 2012 (has links)
We live in a scientific society. Science is all around us. We take scientific principles for granted every time we use technology, such as a car, a computer, or a cell phone. Paradoxically, the scientific literacy of the population is minimal at best. Having a basic knowledge of scientific principles is no longer a luxury but, in today's complex world, a necessity. To increase the scientific literacy of non-science majors, an astrobiology course was developed at the Center for Science and Mathematics Education at The University of Texas at Austin. The course subscribes to an educational philosophy that promotes the significance of teaching science to non-science majors, endorses the importance of multidisciplinary content knowledge, supports the teaching of the nature of science in an implicitly mode, advances the discussion of socio-scientific issues, and includes competent thinking-based teaching strategies using the dynamic discipline of astrobiology. The thesis reviews the problems in scientific literacy, outlines the characteristics of this innovative course, proposes a novel standard - competent thinking - to evaluate scientific literacy and analyzes the results of this course in terms of competent thinking. Data collected provided evidence of an increase of competent thinking skills among the students, especially in terms of self-reflection. Both the first and the second pilot study showed strong evidence that students transitioned from naive to competent thinking arguments. The main study demonstrated that students greatly improve their self-reflecting skills. The final study confirmed improvement in terms of self-reflecting skills, and showed that students gradually improve their arguments based on logic, reason, sophistication, and evidences. Therefore, the results show that this innovative astrobiology course is an effective tool for enhancing competent thinking skills among non-science major students. / text

Där vilda saker är : en didaktisk metod för att formulera upplevelse

Gustafsson, Kristin January 2010 (has links)
Detta arbete undersöker hur man kan bearbeta och formulera upplevelser av en film med hjälp av figural analys. Denna analys har jag hittat i filmvetenskapens fält. Syftet är att med hjälp av denna vidga filmens möjligheter som verktyg i skolan. Tillsammans med en fenomenologisk ansats och gestaltande metod söker jag en didak-tisk metod/upplägg för elever att formulera upplevelser, som ett komplement till tra-ditionell filmanalys.Med utgångspunkt i Svenska filminstitutets filmhandledningar konstaterar jag vad som inte behandlas när man i skolan ser en film. I filmhandledningarna uppmanas eleverna till en diskussion från frågor som rör värdegrunden, och upplevelsen av filmens bilder lämnas därhän. Jag har undersökt det figurala som ett sätt att komma åt möjligheten att formulera upplevelsen av en spelfilm man har sett i skolan, med hjälp av rörliga bilder. Det figurala är ett begrepp som syftar till vårt omedvetna begär och primära fantasi och vår upplevelse. Med en figural analys kan man fokusera på bildmaterialet utan att söka tecken och betydelse för de bildelement man finner. Teknikens möjligeter, såsom dubbelexponeringar, animeringar, hastighetsvariationer och så vidare utgör nya visuella uttryck.I filmen ”Where wild things are” har jag undersökt vad jag kan komma åt i en spelfilm med hjälp av en figural analys. Detta har jag sedan arbetat med i min gestaltande metod som utgår från en filmad skogspromenad. I gestaltningen har jag återberättat scener ur filmen från mitt eget liv, där jag har liknande upplevelser, då upplevelser kan sägas bottna i tidigare erfarenheter. Vidare har jag förstärkt min upplevelse, med teknikens hjälp, i filmredigeringen. Jag har, bland annat, arbetat utifrån Deleuzes tankar om montage som det effektfullaste sättet att med hjälp av teknikens möjligheter bana väg för en upplevelse hos betraktaren. Till min hjälp har jag Karl Hanssons avhandling, ”det figurala och den rörliga bilden” i Filmvetenskap vid Stockholms universitet .Min slutsats är att man i skolsammanhang, utan att nämna ett svårt begrepp som det figurala, kan använda sig av denna analys och metod för att ge elever möjlighet att också få fokusera på sin egen upplevelse, och resonera kring sin egen vardag som något större. På detta sätt kan man lägga fokus på en större del av människan, då hela människan ska få plats i skolan, så som värdegrunden är formulerad.

Caracterização filogenética das proteínas inativadoras de ribossomos (RIPs) de mamona (Ricinus communis L.) e análise da expressão dos genes Rcom RIPs durante o desenvolvimento da semente

Morais, Guilherme Loss de January 2010 (has links)
As Proteínas Inativadoras de Ribossomos (RIPs) compreendem uma família de enzimas que inibem a síntese protéica através da depurinação de uma adenina específica do RNA ribossomal. Os membros desta família são classificados como RIPs do tipo I, quando possuem somente o RNA-N-Glicosidase e RIPs do tipo II quando além do domínio glicosidase, também apresentam um domínio de lectina. As RIPs foram mais estudadas em plantas, onde a ricina e a aglutinina, ambas RIP do tipo II de mamona (Ricinus communis), estão entre as primeiras descritas. O presente trabalho teve o objetivo de identificar parálogos da ricina e aglutinina, bem como RIPs do tipo I de mamona e analisar as suas relações filogenéticas. Além disso, validar o uso de 14 potenciais genes de referência para qRT-PCR em cinco estádios do desenvolvimento da semente de mamona. O padrão de expressão gênica por RT-qPCR de todas RIPs de mamona identificadas, também foram analisados nestes mesmos estádios. Um total de 18 genes de RIPs foi identificado em mamona (Rcom RIPs), dos quais 10 foram classificados como do tipo II e 8 do tipo I. As topologias das árvores filogenéticas sugerem que as Rcom RIPs foram originadas a partir de múltiplos eventos de duplicação gênica. Dois modelos evolutivos foram propostos para a radiação das Rcom RIPs, baseados em processos de fusão gênica associado ou não a eventos de duplicação parcial. Os genes Act 2/7, EF β, Ubi, TIP e UBC foram os que apresentaram perfil de expressão mais estável e foram selecionados para subsequente normalização dos dados de expressão das Rcom RIPs. Os genes que codificam as Rcom RIPI 3, 4, 5, 7 e 8 e as Rcom RIPII 1, 2, 4, 5, 6 e 8 são transcritos em sementes, sendo que a Rcom RIPII 1 (ricina) e a Rcom RIPII 2 (aglutinina) foram as mais expressas. O presente trabalho apresenta um modelo evolutivo das Rcom RIPs, o qual pode ser extrapolado para outras espécies de plantas. Este trabalho também demonstra o primeiro esforço para a padronização de genes de referência para RT-qPCR em mamona e o primeiro que apresenta a expressão outras Rcom RIPs, além da ricina e aglutinina. / Ribosome inactivating proteins (RIPs) comprise a family of enzymes that inhibit protein synthesis, after depurination of an adenine-specific ribosomal RNA. The members of this family are classified as type I RIPs, which have a RNA-Nglycosidase domain and type II RIPs encompassing a RNA-N-glycosidase and a lectin domain.The RIPs were more studied in plants, where ricin and agglutinin, both type II RIP of castor bean (Ricinus communis), were the first to be described. This work aimed to: 1) identifine paralogous of ricin and agglutinin, as well as the type I RIPs of castor bean; 2) analyze their phylogenetic relationships; 3) validate the use of 14 potential housekeeping genes for qRT-PCR for five developmental stages of R. communis seeds; 4) analyze the pattern of gene expression by RTqPCR of all RIPs castor identified in these same stages. A total of 18 genes that encode RIPs were identified in castor bean (Rcom RIPs), 10 of which were classified as type II and 8 as type I. The phylogenetic trees topologies suggest that Rcom RIPs were originated from multiple events of gene duplications. Two evolutionary models have been proposed for the radiation of Rcom RIPs based on gene fusion processes associated or not to events of partial duplication. The genes Act 2/7, EF β, Ubi, TIP and UBC presented the more stable expression profile and were selected for further RT- qPCR normalization experiments. The Rcom RIPI 3, 4, 5, 7 and 8 and Rcom RIPI 1, 2, 4, 5, 6 and 8 genes are actively transcribed in seeds, whereas the Rcom RIPI 1 (ricin) and Rcom RIPI 2 (agglutinin) were the most expressed. This paper presents an evolutionary model of Rcom RIPs, which can be extrapolated to other plant species. Also, corresponds to the first effort to standardize housekeeping genes for RT-qPCR in castor bean and the first that shows the expression Rcom RIPs, other than ricin and agglutinin.

Prostitutionen i Norrland : Socialtjänstens ansvar? / Prostitution in Northern Sweden : The Social Services responsibility?

Sevä, Moa, Lindström, Ylva January 2018 (has links)
Sammanfattning   Syftet med denna studie är att undersöka hur socialtjänsten hanterar och bemöter prostitutionens omfattning bland kvinnor samt identifiera eventuella utvecklingsmöjligheter hos myndigheten. För att besvara vårt syfte har tre frågeställningar formulerats:   <ol type="1">Hur har prostitutionens förekomst förändrats över tid? Vilka insatser/vilket stöd erbjuder socialtjänsten kvinnor som lever i prostitution? Hur skulle arbetet kring prostitution inom socialtjänsten kunna utvecklas och förstärkas?   Denna uppsats fokuserar på hur socialtjänsten möter kvinnor som befinner sig i prostitution. Studien har baserats på kvalitativa intervjuer med socialsekreterare, samordnare och en enhetschef i medelstora kommuner i Norrland. Intervjupersonerna i studien har kunnat förmedla en representativ och tydlig bild över hur det sociala arbetet med prostitution i norra Sverige ser ut. Resultatet visar att prostitutionen har bytt arena och förflyttats från gatan till internetannonser, vilket har lett till en dold men också en tydlig ökning av fenomenet. Något som framkommer av intervjuerna är att i de fall socialtjänsten kommer i kontakt med personer i prostitution, har personerna ofta även ett missbruk där prostitutionen finansierar droger/alkohol/spel. Det identifierades två olika synsätt på hur denna dubbel-problematik skulle bemötas: det ena synsättet betraktade prostitutionen som något sekundärt och som en effekt av missbruket medan det andra synsättet betraktade missbruket och prostitutionen som två lika stora delar av ett omfattande problem där behandling bör ske för båda problematikerna. Resultatet tydliggjorde även de insatser kommuner i Norrland kan erbjuda kvinnor i prostitution, där ett exempel på hjälpinsats visade sig vara socialtjänstens kvinnofridsmottagningar. Ytterligare ett resultat som framkom av studien är att intervjupersonerna identifierar ett behov av tydliga och utarbetade riktlinjer för att kommunerna ska kunna möta den ökade prostitutionen med givna arbetsmetoder och målsättningar.
