Ta täten i loppet om innovation: Fostran av intraprenörskap i stora organisationer - En studie av Volvos New River Valley-fabrik
This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.
Stamräkning och identifiering av åtgärdsbehov i röjnings- och gallringbestånd med hjälp av låghöjdsbilder
This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
Stormskador i lärk och gran : en jämförelse efter stormen Gudrun
The storm Gudrun January 8-9 2005 felled about 70 millions cubic metres forest in southern Sweden. The majority of the wind damaged forest was spruce (Picea abies). In order to decrease the risk of wind damages in the future other trees species are of interest for forestry in southern Sweden.
The purpose of this master thesis was to study if larch were more wind tolerant than spruce. The method was to compare larch, Japanese larch (Larix kaempferi Lamb.), European larch (L.
Underröjning i förstagallring :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers,
SLU. The work was an assignment from Sydved and the aim of the work was to investigate the economical output of removing understorey trees before first thinning.
Four treatments were studied.
- no cleaning before thinning
- cleaning of all trees less than DBH 5 cm before thinning
- cleaning of all trees less than DBH 7 cm before thinning
- cleaning of all trees less then DBH 9 cm before thinning
The result shows a decrease of the cost per m3 for the harvester with about 38% if all trees less than DBH 9 cm was cleaned before thinning compared with the un-cleaned area. At the same time the total net revenue increases with about 22%.

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.
Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
Ta på era "hållbar utvecklingsglasögon"! : Ett idéhäfte som kan hjälpa pedagoger att arbeta mer med hållbar utveckling i förskolan
Natural and environmental issues are everyday parts in preschool but when educators shall consciously work with sustainable development they tend to stop at recycling and what is necessary to be done for achieving the Grön Flagg-certification. I have been observing various preschools and noticed that sustainable development is flawed, often because of the teachers lack of interest, knowledge and in some cases both. Out of this grew an idea of making a project that could help the teachers see how the work with the subject in a fun and educational way can become a part of the preschools everyday routine. I made a tutorial booklet with basic facts and activities relating to sustainable development and the three questions in my report were how much knowledge and interest the teachers initially have, if the tutorial booklet could help the teachers to produce new knowledge and interest for the topic and if it turned out to be easier for them to provide educational activities within the subject. There were three departments that participated in my survey and the methodology of collecting data was an anonymous survey with the teachers' own comments in response.
Interna informationsresurser ? Fallstudie av en statlig myndighet
The aim of this Master?s thesis is to study the relations between internal information and the principal business objectives in a knowledge organization. The questions are: how does the organization behave to its internal information resources, how is the information management related to the principal objectives and strategies, what information policy does the organization develop, and how is the management experienced by the employees. The purpose was to study the supply and management of information designed for internal use and the study was carried out with qualitative, semi-structured interviews to get a picture of the internal information management. The informants were mostly key persons with deep knowledge of internal information.
Utomhuspedagogik i skogen för barn : skötsel och informationsförslag för Stadsliden, en stadsskog i Umeå
Vistelse i naturen har visat sig vara bra för både den fysiska och psykiska hälsan hos barn. Utomhuspedagogisk verksamhet i förskola och skola är mycket viktigt för att barn ska komma ut i naturen idag. Den tätortsnära skogen är en viktig arena för utomhuspedagogik och de utomhuspedagogiska värdena där kan säkerställas med en skötselplan.
Studieområdet Stadsliden är en central och välbesökt stadsskog i Umeå. Skötselplanen för Stadsliden ska nu förnyas och en av de nya målsättningarna för skogen är att den ska erbjuda pedagogiska miljöer för förskola och skola. Kvalitativa respondentintervjuer med lokala pedagoger jämte inventering av studieområdet utfördes för att dokumentera utomhuspedagogiska värden i Stadsliden, i form av skogliga värden samt informationsmaterial.
Studiens resultat visar att pedagogerna främst värdesatte närhet till skogen.
Print quality study of a laboratory offset press
PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a laboratory offset press has been developed and designed, during the past seven years, concerningthis issue. Earlier projects were made concerning the press, e.g.
Undersökning av en industrifastighets material och resurshantering enligt miljöcertifieringssystemet LEED
Miljöcertifieringssystemet för byggnader, LEED (Leadership in Energy &
Environmental Design) lanserades 1998 i USA av USGBC (United States Green
Building Council). USGBC är en icke vinstdrivande organisation, vars mål är att
bidra till utökat hållbart byggande. Skanskas första byggnad som certifierades
enligt LEED färdigställdes 2001 i den amerikanska delstaten North Carolina. I
slutet av februari 2009 offentliggjordes det att Skanska skall införa systemet i sin
Nordiska organisation.
Undersökningen som genomförts handlar om ett av LEED New Constructions sex
delområden, Materials & Resources. Materialhanteringen för ett byggprojekt som
Skanska uppfört har analyserats för att avgöra huruvida det skulle kunna erhålla
poäng vid en certifiering enligt LEED.

For the purpose of definition and elucidation, the study comprises five main themes (see Appendix). The first theme is concerned with motives for choosing a professional career in family therapy. The second theme investigates conceptions of the professional role, while the third theme looks at professional practise and the implications of family therapy work.
Besökarstudie i Kilsbergens rekreationsområden : en metod för att utveckla rekreationsmöjligheter på Sveaskogs marker
In this Master thesis an effective method is presented to find out what is requested in a forest or outdoor recreation. The aim with the study is to find out how Sveaskog can increase the general interest for experiences in nature and improve the access for recreation. Some questions that have been used to answer this purpose are: Who is visiting/not visiting the recreation area? How is it possible to increase the number of visits? The study is carried out in Kilsbergen and mainly centered around Ånnaboda, which is the natural place for people to meet at and undertake recreational activities.
The method that is used is a mail-survey that was sent to visitors and people living in Örebro. People living in Örebro represent potential visitors who live close to the recreation area.
