När en förälder dör : En studie av tre fiktiva tonåringars identitetsutveckling och coping vid förlust av en förälder
The purpose of this study is to examine how the identity of teenagers is affected by the loss of a parent as well as what coping strategies support identity development. The reactions the teenagers exhibit, in such circumstances, will also be examined. To accomplish this, a theory package was created, comprising theories in developmental psychology, identity work, coping and theory of grief reactions of children and teenagers. This package provided a broad perspective, which facilitated the analysis. Furthermore, it made it easier to address the purpose and the issue of the analysis.
?Dead. He is Dead. God blesses America? : Den Amerikanska pressens gestaltning av kriget mot terrorism kring Usama bin Ladins död
Almost 10 years after the attack on World Trade Center Sept. 11 2001, Osama bin Laden was shot and killed on May 2 2011 in Pakistan. How was this event framed by the media with regards to the global war on terror? This study compares two different American newspapers ? the New York Times and the New York Daily News ? and how they framed the war on terrorism in the Middle East from May 2 to May 15 2011. By analyzing the framing in a perspective of the four functions of framing theory: define problems, diagnose causes, make moral judgments and suggest remedies, we found considerable differences in each papers frames.
Factors affecting bark-stripping by red deer (Cervus elaphus) : the importance of landscape structure and forage availability
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Effekterna av urbanisering, barksprickedjup och solexponering på lavfloran i sydöstra Sverige
Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.
Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog
During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Skolträdgården i folkskolans miljö på Gotland : med exempel från Bunge- och Stenkumla skola
The thesis explores the phenomena of historic school gardens connected to elementary schools on Gotland, Sweden. Gotland had the highest percentage of school gardens connected to the elementary schools in Sweden, and by investigating this area much can be learned about the Swedish conditions. The study focus on the period in time when the school gardens were most frequent and used the most, to the point in time when they start losing ground. To bridge over the past to the present the thesis also investigates what is left and play with the thought of possible ways to treat the remains. The main question for the thesis is: How could a school garden on Gotland be constructed and be used 1907 ? 1947?And a follow up question is: What could still be there today and how can/should the remains be treated and conserved? The thesis begin with an overview look at the school gardens of Sweden, closes in with on Gotland and completes with a deeper investigation of two examples of school gardens; Bunge and Stenkumla elementary schools.
Kastanjemalen Cameraria ohridella : livscykel och utbredning i Sverige 2006
Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas.
In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.
Produktivitet och lönsamhet vid skörd av skogsbränsle i klen björkgallring :
The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.
Metod för kartläggning av lövråvara i Södra Skogs verksamhetsområde
Södra Skog chose in 2011 to convert the saw mill in Traryd to a gradually refined sawmill of hardwood. In 2009, they had also acquired the hardwood sawmill in Djursdala. This was strategically important for Södra's business since the demand for hardwood products has increased. The standing volume of deciduous trees in Sweden is today approximately 524 million m3sk and it has increased rapidly in recent years. However, the deciduous forests are to a large extent located in areas that are set aside for nature conservation and is thus not available to the industry.The goal of this work is to create a simple and reliable method for mapping of deciduous wood volumes in areas where Södra Skog is operating (Götaland excluding Gotland).The material that is used is raster databases with estimated forest attributes (kNN-Sweden), data from National Forest Inventory (NFI) and forest management plans.
Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.
Karlstads Kyrkogårdar : En värld full av sociala och ekonomiska skillnader
AbstractA walk at Karlstad's cemetery and burial - grounds is like a strolling in an architectural park with trees, bushes and flowers. But these parks are different; they are filled with dead people, their memorial stones and their life stories. This world is full of socially, economically and culture differences from different times from 19th century till today's society. The cemetery - and burial - grounds in Karlstad can tell you about 19th century influences just by looking at the stones and where they are placed. Influences from the religion, the Christianity, which symbols for example is the cross, the birds and the sun that rises or falls, but also phrases that is directing to the bible.
Mångbruksplan inriktning vilt och viltvårdsanpassning av skogen
This multiple use forestry plan is made on the property Basunda which is located in the southern parts of the province Östergötland. The owners of the property today are Jonas and Ulrik Saanum, but it has been in the family since their grandfather bought it 1933.
There is a slaughterhouse on the property in which they take care of domestic cattle and animals from the forest. Jonas and Ulrik are also dedicated hunters. These are the two reasons to why the focus is wildlife and wildlife management.
The question at issue of this work is simplified: what demands does the wildlife have; and how will the owners be able to fulfill these, what changes in the forest management must be made and will these changes result in a different budget, compared to the ordinary forest management.
This work is based from a freshly made forestry management plan. I based my fieldwork on this plan, but made my own management proposals, that would benefit the game.
Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog
Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.
