Karaktärisering av Gremmeniella-skadade bestånd inom Holmen Skog AB :
Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.
Kostnadseffektiv svaveldioxidreduktion : en studie där ett optimalt svenskt mål jämförs med ett internationellt mål
In Sweden the work of reducing acidification and its prime cause; emission and deposition of sulphur dioxide, has been going on for decades. Despite of all the work that has been done the positive progress in the acidified areas is slow. This is partly due to a long recovery time for the acidified areas but also because the reductions of emission and deposition of sulphur dioxide have not been large enough.
Emissions of sulphur dioxide from land based source in Sweden are estimated to 34 000 tons in the year of 2010. During the same year, approximately 182 000 tons of sulphur dioxide will be deposited over the Swedish territory.
Skolbibliotek och jämställdhet. En intervjustudie på ett mindre antal skolbibliotek
This thesis investigates gender equality at a few Swedish elementary school libraries, and how school librarians at these libraries work with gender equality issues. It is a semi-structured interview study conducted with staff at seven elementary school libraries. Several policy documents state that the school should be a gender-equal environment, but previous research shows that there is still a lack of gender equality, and that staff often treat boys and girls differently. It also shows that boys and girls are often portrayed in a gender-stereotypical way in children?s literature.
Barns rätt och äktenskapsåldern : En kritisk studie av svensk rätt i samband med de grundläggande principerna i barnkonventionen
The Swedish rules for marrying in Sweden are different for swedish citizens and foreigners. A swedish citizen has to have permission from"Länsstyrelsen"to marry before the age of 18 but a foreigner may marry without permission at an age of 15, unless a higher age is required by the foreign law. The main question in this essay is if the swedish international law concerning the age of marriage is compatible with the Convention on the Rights of the Child and/or the Swedish Constitution. The comparison is based on mainly two questions: Primarily the Swedish international law is discussed concerning which marrying age is good for the child. Thereafter it is discussed whether it is discriminating to have different marrying ages for swedish and foreign citizens.
Virkesproduktionen under 80 år i ett fältförsök i Dalarna med olika skogsskötselsystem
I Sverige är trakthyggesbruk med kalhuggning det dominerande skötselsystemetmen intresset för kalhyggesfritt skogsbruk har ökat de senaste åren. Alternativentill kalavverkning är omdiskuterade och kritiseras ofta för att inte vara lönsamma.Målet med detta examensarbete är att analysera ett långtidsförsök med olikaskogsskötselsystem och att diskutera eventuella produktionsskillnader. De fem skötselåtgärdersom undersöktes var 1) kalavverkning med plantering av gran och tall,2) naturlig föryngring under fröträd, 3) blädningsbruk, 4) dimensionsavverkningoch 5) orörd skog (referensyta). Fältförsöket ligger på Siljansfors försökspark iDalarna och anlades 1923. Alla försöksytor har en areal av 1 ha.
Från samförstånd till konfrontation i den svenska utrikespolitiken? : En studie om svensk utrikespolitik mellan åren 1989-2000
This thesis aims at investigating the conflict development of Swedish foreign policy debates during 1989-2000. It is rather assumed that the Swedish foreign policy debates have been highly characterized by a large consensus. Despite that, there have been certain occurrences where the political parties have flushed into party struggle and shown disagreements over the party frontiers. This has raised questions about the range of conflict and consensus in such debates where I have studied the political parties' backchats. I have studied situations where the political parties replicate each other in order to investigate the range of consensus and controversy that exists within different foreign policy areas.
Det sociala området i EU, sett genom dokumenttexterna Romfördraget, Lissabonstrategin, den socialpolitiska agendan och Sveriges strategirapport.
The social dimension in the EU, explored through the document texts of the Treaty of Rome, the Lisbon Strategy, the Social Policy Agenda and the Swedish Strategy ReportThis paper explores the social dimension of EU social policy, except the aspects of the economic and labour market. The EU documents reveal an underlying line of thought stemming from the alignment of the six founding countries, spearheaded by France, with the conservative corporatist welfare model. As one of four European welfare models, the conservative corporatist model emphasises labour market issues, corporate social responsibility and the subsidiarity principle in EU social policy. It also influences how the texts define the terms social, social policy and social exclusion. The definitions determine how policymakers combat problems such as social exclusion and identify the policy issues to be included in EU social policy.The Swedish Strategy shows how the country is responding to the objectives that it has been assigned by the EU and how it plans to attain them.
Visualisering ? ett verktyg för att illustrera långsiktiga konsekvenser av slutavverkning och naturhänsyn
Forestry in Sweden is currently conducted in a manner aiming at equating the production objectives and the biodiversity. To ensure that biodiversity is maintained, patches that are considered to be valuable now or in the future is saved in final fellings. How the tree retention areas will grow into the future forest stands is yet unknown.The purpose of this study was to visualize how different scenarios of natural consideration taken at final felling will evolve in a long term perspective, for two rotation periods. Projections of the forest conditions were executed with the decision support system Heureka and its applications PlanStart and PlanWise. The information about the projected forests was then used for the visualizations which were created in the software Visual Nature Studio.
Till synes orörd skog : naturvärden och kulturhistoria i Rekdalen under 400 år
Nature conservation has for a long time been founded on the assumption that high ecological values depend on low human impact. In Sweden this has led to forests with these characteristics being strictly protected from human influences. However, it is also known that historical land-use can enhance ecological values in forests. Mountainous forests in Sweden, which have not been affected by modern forestry, have for a long time been considered as untouched by people. However, forest history research has in recent years shown that even these areas have been used by people for a long period of time.
Undersökning av självspridning av contortatallen i norra Sverige
Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions.
A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
?Vi har haft tur här på Gotland?? : en studie om socialsekreterares psykosociala arbetsmiljö
The exposed position of a social worker entails serious demands to their working environment. The experience of the working environment is coherent with various circumstances such as physical, technical and psychosocial factors. The aim of this study is to investigate how social workers in Gotland experience their psychosocial working environment. As a theoretical ground we describe the working environment regulations and it´s framework. Previous national and international research enlighten issues such as definitions of threat and violence, the significance of education and policys within social work, social support and riskfactors.
Finns den universella moralen? : En fallstudie av en småstats utrikespolitik
AbstractEssay in political science, C-level, by Bo-Josef Eriksson, spring semester 2007Tutor: Susan Marton?Universal morality - does it exist? - A case study of small states foreign policy?The purpose of this essay is to examine how well does realism stand of against idealism when the focus of the study is on small states foreign policy? The essay takes it?s starting point at the debate between the two theories of international relations (IR). Realism is the theory that has had the most impact on the study of IR since the second world war. Idealism has been it?s greatest opponent and the debate is still active even up til this day.My case study of Danmarks foreign aid policy constitutes a worst critical case scenario for realism and therfore my assumptions were that idealism would be the theory that could explain the core-elements of the Danish foregin aid.
Konvertibla Lån på den Svenska Marknaden: En studie av sex konvertibelemissioner
Issuing convertible bonds for financing purposes has never become widespread practice amongst Swedish companies, in spite of the instrument being common in international markets. Economic theory based on efficient markets suggests that companies should gain no financial benefits from using convertibles and the Swedish situation could be interpreted as in line with this reasoning. However, there are Swedish companies that have chosen to issue convertibles and the Swedish market therefore seems both supportive and contradictory to the existence of benefits of convertible bond financing. Little research concerning the Swedish market has been conducted and the purpose of this explorative thesis is thus to enhance the understanding of the Swedish market for convertibles. This is achieved by conducting in-depth interviews with six listed Swedish companies that have recently issued convertible bonds.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
Musikbranschens syn på folkbiblioteken. En aktör att räkna med?
This thesis explores the opinion of different participants in the music business regarding music being made available at the public libraries. The aim of the thesis is to answer the following questions; which are the most important issues concerning the distribution of music? How do the informants perceive the public libraries mission and activity in regard to make recorded music available? Which are the benefits/disadvantages with music being made available at public libraries? Seven qualitative, semi-structured interviews were conducted with representatives from the following organisations; SKAP (The Swedish Society of Popular Music Composers), FST (Society of Swedish Composers), SAMI (Swedish Artists and Musicians Interest Organisation) SMF (The Swedish Society of Musicians), SOM (Swedish Independent Musicproducers), IFPI (International Federation of the Phonographic Industry) and EMI Music Sweden. A study of literature and articles generated nine themes, which constitutes the frame of reference for the thesis. The result shows that several of the informants have not reflected upon the public library as an important actor when it comes to the distribution of music.
