En tidsseriestudie av varviga sjösediment fra?n Kassjön

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

Högfrekventa tryckvariationer under de senaste århundradena

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

Konsumentprisindex för kläder och skor 1986-2005 - Dekomponering och prognostisering

The essay initially intends to find adequate models to describe and forecast monthly data for the Swedish Consumer Price Index sub group Clothes and Shoes 1986-2005. The time series observations during 2006 are considered ?out of sample period? which is used to evaluate the forecasts. The purpose is to perform time series decomposition and to investigate and analyzethe seasonal pattern. The Box-Jenkins approach is used to find adequate ARIMA models.

Häxor vs. Häxor : En studie av häxor i TV-serier och deras motsvarighet inom wicca

This essay examines how witches are portrayed in American produced TV-series in the year 2000 and forward, what elements could have effected that portrayal in the series and also how this portrayal differs itself from witches within Wicca. The material used for this examination are the TV-series Charmed, The Vampire Diaries and Witches of East End and as comparing literature; Living Wicca, The Spiral Dance and Witchcraft Today. The methods used for this process are discourse analysis and content analysis. I used theories of Pierre Wiktorin about religion and popular culture. I used three themes (Characteristics, Practice and mode of thinking) for the processing of the material and to structure the result.

"Tears are not a Momans Only Weapon" : En historiebruksanalys av HBOs tv-serie Game of Thrones

The middle ages is a time in our history that is often used as a frame when portraying fantasy on tv. HBOs immensely popular series Game of Thrones could easily be counted as one of these. But to what extent does the creators of the series approach the history of our world while creating their own? The aim of this essay is to analyse a number of characters from the tv- series out of gender- and their place in the social structure and then compare the findings with the image of the middle ages that is given in academic research. By analysing the two released seasons of Game of Thrones the study has shown that there are many similarities between the fictional world and the actual world but that it also differs through choices made by the creators of the series. .

Bemanningsföretagens strid i kampen för det mänskliga kapitalet

The study explores collective action in Sweden between 1980 to 1995 using time-series data from the European Protest and Coercion Database. In spite of severe hardship during the crisis of the early 1990s, Swedish strike-rates declined. However, contention merely shifted from workplaces into the streets; there was indeed a protest movement against austerity, as shown by a series of large demonstrations, and some riots, between 1989 and 1993. Further analysis indicates this movement faded as it was increasingly chanelled into the electoral campaign of the labor pary; having won the 1994 election, the organised labor movement no longer had an interest in sustaining the protest movement against austerity..

The Integration of Swedish and global grain markets : a price transmission analysis of wheat

Increased trade and eased policy restrictions have brought markets closer together. Prices at different locations are much likely to affect each other to a certain extent. Since the adaption of Common Agricultural Policy in 1995 the Swedish wheat market has been exposed to the world market and Swedish farmers are facing new challenges. A broader knowledge about market integration and price transmission will facilitate Swedish farmers, banks and politicians in making rational decisions. Therefore the aim of this research is to explain how global wheat prices are transmitted on Swedish wheat prices.

Normföljare eller normbrytare? En studie av mangaserien Ranma ½ ur ett genusperspektiv

The aim of this Master?s thesis is to examine how Ranma ½, one of the most popular Japanese Manga series, reflects the gender system in society. We have chosen to make use of two different gender theorists to determine if Ranma ½ follows the gender norms of society or not. The theoretical framework is based primarily on Yvonne Hirdman's theory of the two basic principles: the principle of dichotomy and the principle of hierarchy. Judith Butler's theory of performative gender is used as a complement.

Finns långserieböcker för barn och ungdomar på biblioteket?

The aim of this masters thesis is to examine to what extent series books for children and youth are included in the acquisitions of public libraries. It also examines which needs series books fulfil among a group of 13-15 year old children. The main question of this thesis was: To what extent do libraries provide series books for children and youth? An inquiry investigation showed that a majority of the libraries in Sweden provide these books. The main reason to provide the books was that the demand is large.

Finansiella nyckeltal i svenska börsbolag - En empirisk studie av historiska värden och förekomsten av konvergens till långtidsmedelvärden

Practitioners of financial statement analysis are dependent on key ratios in a multiple number of situations, one in particular being equity valuation. A lack of historical benchmarks, and knowledge regarding the time series behaviour of such ratios, has been identified regarding Swedish companies. Therefore, this study sets out to provide such data and knowledge. Companies listed on the Stockholm Stock Exchange are examined over the period 1979-2009 where the sample is divided into nine industry groups. Historical values for eight common key ratios are documented with regards to median, mean, standard deviation and percentiles.

Att genom fiktion skildra en verklighet : En kvalitativ studie i hur maktstruktrurer beskrivs i BBC:s tv-serie The Hour

The objective of this study was to investigate how power relationships between journalists and politicians were shown in the fictional BBC tv-series ?The Hour?.

The situation method was useful to get a perception of the relations between the participants .The text analysis we used to analyse what was said in the tv-series and to interpret underlying motives.The fictional form necessitated a personalization of power structures, in the sense that each and every power was represented by a single character; political power was for instance represented by the character of Angus McCain.
