Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.
Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood
Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the
biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last
50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Privata skogsägares attityder och anpassningar till klimatförändringar : En fallstudie i Kronobergs län
Conditions for Swedish forestry are expected to change in the future due to the climate. Among other things, increased production is expected in a warmer climate, mainly because of a longer growing season. With the changing climate risk of damage by such as insects, fungi and storms are expected to increase. Hence, it is of highest importance for private forest owners to spread these risks in the way they cultivate their forest. In this study a qualitative method was used to examine ten private forest owners with forest properties within Kronoberg county, Sweden in their attitudes and actions to prepare in terms of climate change and if they have been affected by the climate change debate in their forest decisions.
Användning av satellitdata för lokalisering av skogsområden där lövröjning bedöms angelägen : en analys av användbarheten med fjärranalys som hjälpmedel till röjningsrådgivning
This master thesis project is a part of a project called ?Järboprojektet? at the regional board of forestry, the district of Gästrikland. The project will give answers to questions regarding if an analysis of satellite images can be used to contact and inform landowners of the located areas where precommercial thinning is useful. The whole project is a part of the National Board of Forestrys IT-stake where the analysis of satellite images will, at the latitudes possible, be adapted to each district in purpose to identify these areas in need of precommercial thinning. This master thesis project is based on a field inventory of identified objects where precommercial thinning is useful.
Ekonomelevers extrajobb under gymnasietiden : Utvecklingsmöjligheter för studie- och yrkesvägledningen
The knowledge of early employment experiences has evolved over the last decade in countries such as Australia and Great Britain. In Sweden, this type of research is still unusual and the aim of this study was to break new ground by highlighting some areas that could be of extra interest in the Swedish early employment research to come. A focus in the study was to give an overview of what job sectors school students work in; and the amount of jobs aquired through school-organized work placement, private social networks or personal marketing of own merits. In addition to this, a multi variate analysis was carried out to find patterns in the picture of early employment experiences among students at upper secondary school. The findings of the study has relevance for ways of conducting career counselling and therefore the general aim of this study is to point out the importance of developing the practises of vocational psychology.A survey among 74 teenaged school students with economics as their main subject has been carried out in a mid-size Swedish city May 2012.
Entreprenörskap på landsbygden : 6 små livsmedelsförädlande företag i Mälardalen
For a long time, economic activity has decreased and shows a downward trend in the food sector. To break this requires efforts to strengthen corporate position with the ability to meet market challenges.
In the small producers is a great potential for them to be able to increase its profitability thanks to its ability to offer added value in the product. But to achieve this requires not only a willingness and creativity out of the ordinary but also factors that lead us into this report, current issues. The issues are related to marketing, brand building and the importance of developing a stable network.
The study aims to investigate how small businesses operate in rural areas are experiencing the possibilities of support from various networks and organizations and that, from a business perspective, and also see which areas that they need more support in to achieve a growing business. The work has been followed by an inductive method, when we initially could not say anything about the empirical results.
Long-Term performance of Swedish IPOs - 1990-2002
We have performed a study much similar to Ritter?s (1991) about long-term aftermarket performance of IPOs on the Swedish market during the years 1990 to 2002. The study resulted in evidence for that Swedish IPO do underperforms their benchmark-portfolios during a 36-months period. Though, the grade of underperformance depends of the chosen benchmark. The study is mainly focused on a particular benchmark, a portfolio of non-issuing firms matched by size and sector.
Assessment methods for corporateresponsibility on the fashion scene : a case study of Hennes & Mauritz, Lindex, Kappahl and MQ
Assessing the outcome of corporate responsibility is often argued to be complicated due to long-term effects and qualitative aspects. Epstein (2008, p.261) establishes that: ?Though many think that sustainability is too difficult to measure, companies have found that unless the impacts are measured, they are commonly ignored in the resource allocation process?. Corporate responsibility is often referred to as a business case, i.e., that social and environmental concern add value to the business (Heikkurinen, 2010; Porter & van der Linde, 1995). Hence, for corporate responsibility to be a business case a strategy, corporate structure and systems, programmes and actions linked to performance measures need to be in place to assess the outcome; environmental, social as well as financial.
Deltidsarbetandes företrädesrätt till högre sysselsättningsgrad
During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.
Att mäta fattigdomsbekämpning - En studie av social performance-rapportering inom mikrofinans
This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.
Återväxt av blåbär (Vaccinium myrtillus L.) efter ångbehandling : orsaker till effektiv kontroll
Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.
Samband mellan laserdata och fältdata
To make it easier for forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results.
This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.
Hållbart skogsbruk och naturvård ? ett skogsägarperspektiv
The Swedish government has set up 16 environmental goals for Sweden to achieve. One ofthem is ?Living forests?, which is the foundation for the ?National strategy for the formalprotection of forests?. The ?National strategy? puts the private forest owner at the centre ofattention in order to achieve the environmental goal ?Living forests?.
