Bakgrund: Av alla gravida kvinnor räknas omkring 5 % lida av svår förlossningsrädsla. Kvinnor med förlossningsrädsla löper högre risk för komplikationer under och efter graviditeten. I Sverige läggs idag mycket resurser på Auroraverksamhet för att hjälpa kvinnor med förlossningsrädsla. Det saknas omfattande utvärdering av Auroraverksamheten. Syfte: Syftet med detta fördjupningsarbete var att undersöka upplevelse och effekt av Aurorasamtal inför förlossning samt upplevelse av den efterföljande förlossningen bland först- och omföderskor. Metod: Studien har en retrospektiv studiedesign där datainsamling skedde via en enkätundersökning. Datamaterialet sammanställdes därefter i SPSS. Resultat: Majoriteten av kvinnorna upplevde att samtalen hjälpte dem till en mer positiv förlossningsupplevelse. Fler förstföderskor än omföderskor önskade planerat kejsarsnitt när de kom till Auroramottagningen. De flesta kvinnor som önskade vaginal förlossning blev vaginalt förlösta. Över hälften av kvinnorna som deltog i studien var mindre rädda för förlossning 1 – 2 år efter förlossningen än de upplevde att de var innan Aurorasamtalet och förlossningen. Konklusion: Aurorasamtal förefaller ha störst betydelse för omföderskor och för de kvinnor som önskar vaginal förlossning. / Background: About 5 % of all pregnant women suffer from severe fear of childbirth. Women with fear of childbirth are at higher risk for complications during and after pregnancy. In Sweden a lot of resources are being spent on Aurora counselling to help women with fear of childbirth. There is no comprehensive evaluation of Aurora counselling though. Aim: The aim of this study was to examine the experience and impact of Aurora counselling for childbirth as well as the experience of the following birth among primipara and multipara women. Method: The study had a retrospective study design in which data was collected through a survey. The data was compiled in SPSS. Results: The majority of women felt that the Aurora counselling has helped them to experience a more positive birth experience. More primipara than multipara desired an elective caesarean section when they came to Aurora Clinic. Most of the women who desired to have a vaginal birth became vaginally delivered. More than half of the women who participated in the study were less afraid of childbirth 1 - 2 years after the birth than they estimated they were before the Aurora counselling and childbirth. Conclusion: Aurora counselling seems to have the greatest impact on multipara women as well as on women who desire vaginal birth.

Information is power in the 21st century. The on-going “information revolution” has forced states to adapt to the new world arena and to the following demand of being able to use information strategically. This study aimed to contribute to the lack of research regarding the Swedish case, and thus give a greater understanding of how Sweden tackles information warfare campaigns. The study examined two cases: The host-nation-agreement between Sweden and NATO (2016) and the Swedish military exercise, Aurora 17 (2017). The study applied a qualitative analytical method to: firstly, identify the Swedish strategic narrative by using governmental policy documents; secondly, identify the Russian intrusive narrative by looking at two cases using editorial articles of RT and Sputnik International, and finally analyze the Swedish way of handling the intrusive narrative, using an ideal type analysis method.  The study confirmed that Russia, through state-owned media, intervened and tried to undermine the Swedish strategic narrative in both cases. The study concluded that Sweden’s strategy to counter these actions is moving from a previously passive approach – to a more antagonistic approach towards the sender of the intruding narrative. However, the study also concluded that Sweden is lacking a coherent strategy to handling these kinds of threats.

Incoherent scatter radar (ISR) measurements were used in conjunction with plasma simulations to study two micro-scale plasma processes that commonly occur in the auroral ionosphere. These are 1) ion acoustic turbulence and 2) Langmuir turbulence. Through an ISR experiment we investigated the dependence of ion acoustic turbulence on magnetic aspect angle. The results showed a very strong aspect angle sensitivity which could be utilized to classify the turbulence according to allowable generation mechanisms and sources of free energy. In addition, this work presents results that led to the discovery of a new type of ISR echo, explained as a signature of cavitating Langmuir turbulence. A number of incoherent scatter radar experiments, exploiting a variety of beam and pulse patterns, were designed or revisited to investigate the Langmuir turbulence underlying the radar echoes. The experimental results revealed that Langmuir turbulence is a common feature of the auroral ionosphere. The experimental efforts also led to uncovering a relationship between Langmuir turbulence and one type of natural electromagnetic emission that is sometimes detected on the ground, so-called “medium frequency burst”, providing an explanation for the generation mechanism of these emissions. In an attempt to gain insights into the source mechanism underlying Langmuir turbulence, 1-dimensional Zakharov simulations were employed to study the interactions of ionospheric electron beams with a broad range of parameters with the background plasma at the F region peak. A variety of processes were observed, ranging from a cascade of parametric decays, to formation of stationary wave packets and density cavities in the condensate region, and to direct nucleation and collapse at the initial stage of the turbulence. The simulation results were then compared with the ISR measurements where inconsistencies were found in the spectral details and intensity of the simulated and measured Langmuir turbulence echoes, suggesting the possibility that the direct energy for the turbulence was provided by unstable low-energy (5 − 20 eV) electron populations produced locally in the F region of the ionosphere rather than by electron beams originating from the magnetosphere.

En síntesis, para dar respuesta a las interrogantes señaladas en la presente tesis, se investigó sobre la situación particular de la mujer chilena de élite dentro del entorno social del siglo XIX, especialmente durante la segunda mitad, su modo de vida, su educación y el rol que desempeñó en la sociedad. Posteriormente, se indagó en las características y el desarrollo de la pintura chilena, junto con sus principales exponentes y, derivado de ello, la incorporación femenina al quehacer artístico nacional, sus precursoras extranjeras y la primera generación. También se analizó el entorno familiar en el que crecieron ambas hermanas, sus estudios e influencias. Se examinó el significado de su breve, pero maciza participación en los Salones de Pintura entre 1883 y 1895 y su temprano alejamiento; las impresiones con que fueran recibidas y los cuestionamientos que se generaron a partir de su aparición en la vida pública. Finalmente, la tesis presenta un análisis de la obra pictórica de las hermanas Mira Mena, lo que permite al lector formarse un juicio acabado sobre su significación en nuestra pintura.

x, 60 p. : ill. (some col.) / Regulation of stem cell self-renewal versus differentiation is critical for embryonic development and adult tissue homeostasis. Drosophila larval neuroblasts divide asymmetrically to self-renew and are a model system for studying stem cell self-renewal. Here, we identify two proteins involved in distinct steps of the cell cycle that regulate neuroblast self-renewal. We first describe three mutations showing increased brain neuroblast numbers that map to the aurora-A gene, which encodes a conserved kinase implicated in human cancer. Clonal analysis and time-lapse imaging in aurora-A mutants show single neuroblasts generate multiple neuroblasts (ectopic self-renewal). This phenotype is due to two independent neuroblast defects: abnormal atypical protein kinase C (aPKC)/Numb cortical polarity and failure to align the mitotic spindle with the cortical polarity axis. numb mutant clones have ectopic neuroblasts, and Numb overexpression partially suppresses aurora-A neuroblast overgrowth (but not spindle misalignment). We conclude that Aurora-A and Numb are novel inhibitors of neuroblast self-renewal and that spindle orientation regulates neuroblast self-renewal. We next identified an sgt1 (suppressor-of-G2-allele-of-skp1 ) mutant that had fewer neuroblasts. We found that sgt1 neuroblasts have two polarity phenotypes: failure to establish apical cortical polarity at prophase and lack of cortical Scribble localization throughout the cell cycle. Apical cortical polarity was partially restored at metaphase by a microtubule-induced cortical polarity pathway. Double mutants lacking Sgt1 and Pins (a microtubule-induced polarity pathway component) resulted in neuroblasts without detectable cortical polarity and formation of "neuroblast tumors." Mutants in hsp83 (encoding the predicted Sgt1-binding protein Hsp90), LKB1, or AMPKα all show a similar apical cortical phenotype (but no Scribble phenotype), and activated AMPKα rescued the sgt1 mutant phenotype. We propose that an Sgt1/Hsp90-LKB1-AMPK pathway acts redundantly with a microtubule-induced polarity pathway to generate neuroblast cortical polarity, and the absence of neuroblast cortical polarity can produce neuroblast tumors.

Os ambientes distribuídos formados por essas redes possuem um grande potencial de processamento. Todavia, para que se possa aproveitar tal capacidade de processamento, faz-se necessário a utilização de um sistema que gerencie todo esse ambiente distribuído. Os sistemas operacionais distribuídos vêm ao encontro dessa necessidade. Os sistemas operacionais distribuídos caracterizam-se por permitir que seus usuários utilizem os recursos espalhados pelo ambiente distribuído de maneira transparente, escondendo os detalhes da implementação. O mecanismo de comunicação nesses sistemas é muito importante pois garante que componentes do sistema possam interagir a fim de executar uma determinada tarefa. Este trabalho descreve a solução para comunicação remota entre objetos no sistema operacional Aurora. O Aurora é um sistema operacional reflexivo projetado para arquiteturas multiprocessadas. A solução desenvolvida caracteriza-se por estender o mecanismo de comunicação local para permitir que o mesmo também suporte a comunicação remota de objetos. A comunicação entre objetos distribuídos em Aurora atende o requisito de transparência em sistemas distribuídos e é compatível com o modelo reflexivo do sistema.
