Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
Vem är det framför skärmen? : En fördjupad textanalys om hur svenska politiker konstruerar jag-bilder på Twitter.
The trend of social media is a global hit and now both individuals, businesses, celebrities and politicianshave their own social media pages, which means that the visibility increases and focus lies on what'swritten and published by the person. Mediated communication are everywhere around us and affects theway we communicate with each other and also the way we look at ourselves and most importantly how weportray ourselves. The individual's perspective has become a relevant issue with the rapid moderndevelopment. One's cultural identity can be seen as a life-long project.The purpose of this paper is to do an in-depth text analysis to examine how Swedish politicians constituteand construct identities, with a focus on "the self" and the "mediatization self" on the micro-blog Twitter.The theoretical ground for this study is from a discourse analysis point of view that focus on ?the self? andthe ?meditization self?.
Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker
The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines.
This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments.
The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done.
The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..
Apologia i offentligheten : En studie av Ola Lindholms retoriska försvar mot Expressens kokainanklagelser
On the 12:th of April 2011, the Swedish tabloid magazine Expressen publishes a story, claiming that Ola Lindholm, presenter of critically acclaimed TV-show ?Wild Kids? has been suspected and apprehended on cocaine allegations. The serious allegation called for Ola Lindholm to defend himself against the allegations. His only public response was a blog-post where he claimed his innocence, albeit with some reservations. The purpose of this paper is to analyze Lindholm?s rhetorical defense.
Val och kompensation : En studie av lärares arbetssätt med materialet ABC-klubben
This study, based on the socio-cultural theory of the book as a mediating tool, examines how four teachers say they work with the reader ABC-klubben. This is done with a focus on how they reason about choosing the level of readers for the pupils and about what compensation, if any, they make for pupils who read the simpler book and therefore miss the more difficult words and expressions. The result shows that all the teachers say that they take the pupils? motivation for and pleasure in reading as an important ground for the decision as to which reader a pupil should use, and that this decision is taken with a focus on the individual. When it comes to compensation for the pupils who read the simpler book, the teachers do not describe consistently focused work on this, but they describe a similar way of working whereby they nevertheless acquaint these pupils with the more difficult book and the harder words and expressions.
Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren
The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.
Kommunikation i Designer- Klientinteraktionen : Användning av objekt för att uppdatera Common Ground
En designers främsta uppgift är att hitta lösningar på problem som är svårformulerade vilket kräver full förståelse för designsituationen. Interaktionsdesignern fungerar dessutom som länk mellan olika aktörer i en beställarprocess med syfte att tillgodose slutanvändarens behov, som ofta faller mellan stolarna. Avsikten med denna rapport är att studera hur interaktionsdesignern kan vara den kommunikatör som krävs. Detta har gjorts genom att titta på hur objekt används i kommunikationen mellan designern och dess klient. Studien är gjord genom en videoanalys som tolkats utifrån Herbert H.
Ett litet ord med stora implikationer : En studie om förståelsen kring ordet Gay i allmänt negativ bemärkelse
Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.
Uttorkning av lera : Orsaker och följder
When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees. The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.
Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd
Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT.
The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.
Distribution av känslig data
Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.

The study is based on a symbolic interactionistic theory and explores the experiences and unique perceptions of these women in their life as stepparents.
Från neutralitet till öppenhet? : En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slut
Abstract Title: Från neutralitet till öppenhet? ? En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slutAuthor: Jens KindhSupervisor: Patric LindgrenLinnaeus UniversityDepartment of Political ScienceSpring term 2012 When the Cold War ended, a new security situation was unfolded in Sweden. The purpose of this thesis is to describe and compare how the Swedish security policy is organized and how it has changed since the Cold War ended. To do that, I?m going to try answer the following questions:How is the Swedish security policy organized?What defence resolutions have affected the Swedish security policy after the Cold War ended?How has different political actions made its impact on the Swedish security policy after the Cold War ended?My theory is to try explain how the Swedish security policy has changed after the Cold War through a realism security perspective called traditional security, which refers to a realistic construct of the states security policy.
