A study of shock-metamorphic features in zircon from the Siljan impact structure, Sweden

För att kunna fastställa om en misstänkt nedslagsstruktur verkligen bildats genom ett meteoritnedslag så används så kallade chockstrukturer som planar deformation features (PDFs) och i vissa fall planar fractures (PFs) som indikatorer. Tidigare studier har visat att kvarts och kalifältspat från nedslagsstrukturen Siljansringen innehåller bland annat PDFs. I denna studie har zirkon från samma lokalShock-metamorphic features such as planar deformation features (PDFs) and in some cases planar fractures (PFs) are widely used as impact-indicators when to confirm a suspected impact structure. These features only develop when exposed to a sudden and immense pressure and temperature increase in association with meteorite impacts. In previous studies, quartz and k-feldspar containing PDFs have been

Assessment of the relationship between the Photochemical Reflectance Index and Light Use Efficiency : a study of its seasonal and diurnal variation in a sub-arctic birch forest, Abisko, Sweden

Fotosyntes, vilket beskriver upptaget av koldioxid från atmosfären av vegetationen, är nyckeln till den naturliga förmildringen av den antropogena klimatförändringen. Dess korrekta skattning är därför av avgörande betydelse för korrekta bedömningar av den globala kolbalansen och förståelsen av det globala kolets kretslopp. Detta upptag av kol kallas bruttoprimärproduktionen (Gross Primary ProductiPhotosynthesis, which describes the uptake of carbon from the atmosphere by vegetation, is key to the natural mitigation of anthropogenic climate change. Its accurate assessment is therefore of vital importance for correct estimates of the global carbon balance and the understanding of global carbon dynamics. This uptake of carbon is referred to as the gross primary productivity (GPP) and can be r

Can FAVAR improve Swedish inflation forecasting?

The purpose of this thesis is to investigate whether factor augmented vectorautoregression (FAVAR) models estimated using principal component analysis are able to improve monthly inflation rate forecasts for Sweden. We produce 42 forecasts for the period January 2012 to June 2015 and evaluate the forecasts by their root mean square errors as well as their ability to correctly predict the sign of t

The Predictive Power of Candlestick Patterns - An Empirical Test of Technical Indicators on the Swedish Stock Market Using GARCH-M and Bootstrapping

Genom att använda statistiska tester så testas lönsamheten och prognosförmågan av en teknisk analys strategi baserad på candlestick mönster. Analys av Candlestick mönster är en kortsiktig strategi baserad på öppnings-, hög-, låg- och stängningskurser för en finansiell tillgång. Resultaten visar att strategin inte är lönsam på kort sikt och att den inte har någon prognosförmåga när den appliceras pUsing statistical tests, the profitability and predictive power of a technical analysis strategy based on candlestick patterns is tested. Candlestick technical analysis is a short term strategy based on the open, high, low and closing prices of a financial asset. The results show that the strategy is not profitable in the short term and has no predictive power when applied to 29 OMXS30 stocks over

New Product Development: Idea Evaluation and the Differences between Ideas having High and Low Levels of Innovation. An Investigation in the Swedish Food Industry

Thesis Purpose: This study has a twofold purpose. First, the authors want to contribute to research on idea evaluation in the fuzzy front end by specifically shedding light on the food industry as this sector differs from other industries (Galizzi & Venturini, 1996; Tidd & Bessant, 2014; Triguero, Córcoles & Cuerva, 2013). Second, different evaluation criteria will be outlined for high

Energy auditing and enhanced implementation of energy efficiency strategies and actions through networks for SMEs – learning across borders in Sweden, Germany and Switzerland

Rapporten innefattar en detaljerad beskrivning och utvärdering av de existerande tyska och schweiziska nätverk för energieffektivisering. Baserat på resultatet, finns även ett förslag på en modell för energieffektiviseringsnätverk anpassad för Sverige som består av fyra faser: rekryteringsfas, energikartläggningsfas, nätverksfas och uppföljningsfas. Från studien drogs även slutsatsen att de viktig

Can dietary fat intake modify genetic associations with blood lipid level? Observations from a Swedish cohort study

Humans have for a long time contemplated the link between diet and disease. As early as 400 BC, Hippocrates, commonly referred to as the father of western medicine, stated, “let food be thy medicine and let medicine be thy food”. Today, a poor diet is still considered one of the major risk factors for common complex diseases such as cardiovascular disease (CVD). CVD refers to a class of diseases

Performance measurement system for warehouse activities based on the SCOR® model : A research study in collaboration with Consafe Logistics AB, Sweden

Background: SCOR is a worldwide accepted and renowned process reference model that is developed and endorsed by the non-profit organization Supply Chain Council. It’s a cross-industry diagnostic tool for supply chain management. Consafe Logistics wanted to know if a performance measurement system for warehouse activities could be developed based on the SCOR model, and how it could be applied in th

Depositional history of the Neoproterozoic Visingsö Group, south-central Sweden

De neoproterozoiska sedimentära bergarterna i Visingsögruppen är en av få kvarvarande spår från den här tidsperioden i Sverige. Tack vare dessa har vi en möjlighet att förstå hur landskapet såg ut under denna tiden. De olika miljöfaktorer som påverkade sedimenten när dessa deponerades är nyckeln till att kunna måla en större bil. Det vi ser i Visingsö-gruppen är hur en lokal, förhållandevis grund,The Neoproterozoic sedimentary rocks of the Visingsö Group are one of few remaining rocks from this time. They provide a vital clue to understanding how the landscape looked at this time. The various environmental factors that prevailed and affected deposition are key to paint a bigger picture. The Visingsö Group shows how a local, fairly shallow, environment is subject to a long-term transgressio

The Woman Was Raped - A Critical Discourse Analysis of Swedish News Media Coverage of Rape and Sexual Assault

Departing from the question of how linguistic representations of sexual crime are connected to social practices around sexuality, this discourse analysis looks into 30 news articles on sexual crime to identify discourses around male and female sexuality. As most sexual crimes are committed by men and against women, the analysis focuses on connecting discursive descriptions of men and women in rela

Mass Emigration and Political Change: Evidence from Historical Swedish Elections

Migrants do not only affect the societies in which they arrive. When people leave in large numbers, their absence will also have indirect consequences for the societies from which they left. Between 1860 and 1930, 1.4 million Swedes emigrated abroad, most of them settling in the United States. In this essay I look at how this historic migration episode, in which a quarter of the population left th
