Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.
Varför var det så svårt? : En flermetodsanalys av läsbarhet av nyhetsartiklar i Dagens Nyheter under 15 år
The aim of this study was to examine the readability of news articles published in the Swedish national newspaper Dagens Nyheter during the years 1999 - 2013. Our hypothesis was that the written language in newspapers is simpler today than it was 15 years ago. To measure the possible change of the written language in a quantitative study we chose to use a method to calculate the readability of 30 news articles, two from each year. We could not see any development of the language level so we chose to do a complementary qualitative study of the layout and presentation of the news articles. This secondary study showed a significant change in how news is presented throughout the years.
EU och folkomröstningarna En undersökning om de europeiska ländernas skiftande karaktär och hur dess väljare agerat i förhållande till detta
33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.
Blatte - en etnicitet? Om ungdomars med utländsk bakgrund syn på sin etnicitet
Immigrants and children of immigrants are statistically lumped together into a category of "person with foreign background". Blatte is a degrading and violating word when directed at immigrants by Swedes. The aim of my essay was to test to what extent the Swedish term "blatte" could be qualified as an ethnicity in the sense that young people with foreign background born between 1981 and 1984 living in a neighborhood with a high population of people with foreign backgrounds have another ethnicity, besides the Swedish and the "home country ethnicity" to find themselves and their identity in.My method consisted of interviewing six people between the ages of 21 and 24 with different ethnic backgrounds living in a limited area of Malmö, Sweden´s third biggest city. I tested my hypothesis of these people having a third ethnicity to relate to against three schools and from two out of three schools defending my hypothesis, my result is that blatte can not fully be seen as an ethnicity but definitely shows tendencies of becoming one in the future..
Kommunala skulder : Har fragmentering i den styrande församlingen någon effekt på de kommunala skuldnivåerna?
Denna uppsats syftar till att testa The Weak Government Hypothesis. Hypotesen är att en fragmenterad regering ackumulerar större skulder än ickefragmenterade regeringar och att graden av fragmentering påverkar storleken på skulden. Hypotesen testas med paneldata över 283 svenska kommuner under perioden 1996-2004. Resultaten från den empiriska studien ger inte något enhälligt stöd åt hypotesen. Studien finner dock visst stöd för att en lokal koalitionsregering bestående av flera jämnstora partier tenderar att ha en positiv effekt på de långfristiga skuldnivåerna under valår.
VD-bytets påverkan på aktiekursen : En studie ur ett genusperspektiv
In the last decades the Swedish labor market has been characterized by a stereotype perception on women?s role and position on the market. The perception speaks of the characteristics of female leadership as being less qualified causing the gaps between the two genders to transform into a gender segregated society. The historically slow progress has limited the career opportunities for women to reach top management. However the increasing discussions during the 21st century on how to reduce the gender differences in the labor market has made it more acceptable with women on higher positions.
Ska man tro på aktie-Nostradamus? : en studie om aktierekommendationers värde för privata investerare
Intro: 80 percent of the Swedish population own shares. This makes Sweden the leading country in private investment in securities. It can be difficult for the private investor to know where, when and which security to invest in. The strategies are as ambivalent as the stock markets fluctuations. If the investor prefers to refrain from investing money himself, there are brokers who carry out these types of services.
Kan kombinationen av dehydrering, kronisk stress och/eller endotoxemi vara orsaken till träningsinducerad lungblödning?
Thoroughbred racehorses have suffered from exercise-induced haemorrhage for over 300 years. Almost all competing horses develop exercise-induced pulmonary haemorrhage (EIPH) at some point but most horses don?t suffer from reduced competing capacity due to the disease. The cause of the exercise-induced haemorrhage is unknown. The most believed theory today is that EIPH is induced by pulmonary stress failure caused by pressure over 100 mmHg in the pulmonary arteries during exercise.
Optimal kapitalstruktur : En undersökning tillämpad på skandinaviska och tyska företag
This paper describes and develops a trade off model of optimal capital structure by Bradley et al. (1984). The model is then tested to examine how changes in corporate tax rates affect the optimal capital structure of firms. Based on theoretical implications of the model, four hypotheses are derived stating that firms? optimal debt-to-value ratio is (1) negatively related to financial distress costs, (2) negatively related to non-debt tax shields, (3) negatively related to firm volatility and (4) positively related to the corporate tax rate.
Tid kontra pengar : Goal-gradient effekt vid valet mellan nettonuvärdesmetoden och återbetalningsregeln
Syftet med denna uppsats var att studera om det finns en målgradient vid investeringsbedömning som medför en preferens för alternativ med kort återbetalningstid och snabba belöningar. Vi valde att genomföra denna studie med hjälp av en kvantitativ ansats, då vi genomförde ett experiment med studenter vid Blekinge Tekniska Högskola. Detta motiverar vi med att utifrån vårt syfte och vår teoretiska referensram, ger det oss störst möjlighet att generera ett intressant och relevant resultat. Vårt resultat visar tydligt att beslutsfattare föredrar att använda återbetalningsregeln före nettonuvärdesmetoden i en beslutssituation, och därmed ett fokus på tidsaspekten och när en investering är återbetald. 81 % av våra respondenter valde tidsalternativet i minst ett av de två casen.
Rumslig utbredning av tuberkulos : Stockholms kommun år 2002-2011
This bachelor thesis is written as a part of the geography program at Stockholm University, Sweden, and the study was conducted from April to June 2012.Tuberculosis (TB) is an airborne disease and one of the most widespread infectious diseases in the world with more than nine million new cases each year (SMI 2012, digital source). The disease is a major source of death and suffering in many places and the number of deaths remains high despite the availability of highly efficacious treatment. To control and prevent further spread of TB, the mapping of the disease spatial distribution is of essential importance.In this study, maps were produced that shows the spatial distribution of TB between the years 2002 to 2011 in the municipality of Stockholm. These maps allow an analysis of the spatial distribution at a local scale over time.The aim of this paper is to study how the spatial distribution of TB has looked like in the municipality of Stockholm the last 10 years and to analyze why the spatial distribution of the disease looked like it did. This study is based on the hypothesis ?drift?.
Det stör inte ? det sticker lite i ögonen bara : En fallstudie om ensamkommande barns boende och grannskapskontakters betydelse för integration
In recent times the number of children and youth, that have been forced to flee to Sweden due to various circumstances, has increased. The majority of said children and youth seek refuge along with their parents. In recent years, however, the count of this mentioned group, coming separately from their parents, has gradually increased. Children in such situations are called unaccompanied children. A knowledge gap in previous research, regarding the commitment of unaccompanied children, might be filled by neighborhood attentiveness to residential care homes i.e.
Social preference and diet learning in goat kids at pasture
AbstractHerbivores can be classified into either hiders or followers depending on their postpartum behaviour. The two behaviour types affect the spatial relationship between the mother and her infant. Goats are seen as hiders, although the environment plays a central role when it comes to the behaviour. Therefore, in the first part of this study the aim was to investigate how the goat kids? spatial relationship changed in the transition from indoor housing to pasture.
Storstadssatsningen och dess effekter på valdeltagande i kommunala val: Framgång eller misslyckande?
In 1998 the Swedish Socialist Government initiated a project in order to promote economic growth and to end the discriminating social and ethnic segregation in the greater city regions of Stockholm, Gothenburg and Malmo. One of the goals of the project was and still is to promote political participation in 24 of the poorest areas of the three cities. In a quantitative analysis I evaluate whether or not the project so far has been successful in promoting a specific part of political participation, i.e. electoral participation in communal elections. The results of the 24 poor city areas are compared with a group of 14 likewise poor city areas of major swedish cities.According to my hypothesis, general improvements of the socio-economic status of poor city areas ought to generate positive effects on electoral participation in communal elections.
Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik
This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.
