Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Boven i det interna samspelet : En uppsats om kommunikationen mellan sälj- och logistikavdelning på industriföretags påverkan på det interna materialflödet
We have left the industrial society, and instead, we live in a post-industrial knowledge and information society. It is often said that industrial production has disappeared or that it has changed greatly. This means that fewer are employed in the manufacturing sector while the service sector is increasing, resulting in that the boundaries between production and administration decreases. The production goes from mass production to more flexible and specialized solutions. This puts greater demands on the logistics chain that continually need to work to meet customer requirements.
"Vi kunde ha varit bättre..." : En fallstudie om internkontroll i Sverige
???This study has been made with the purpose of gaining an understanding of how a Swedish company may think and act concerning their internal control. An American body, COSO, have for some time published documents containing guidelines for how companies should go about this process, however, when conducting this study we were not aware of the extent to which companies in Europe and mainly Sweden used them. In order to learn about this, and also to gain an understanding of when these guidelines are appropriate, we conducted a case study with a large-sized, multinational Swedish company. We also conducted an interview with an expert in internal control monitoring, Anna-Clara af Ekenstam of Pricewaterhouse Coopers, in order to get the perspective of the evaluators in this process and to gain some insight as to whether our case is typical in Sweden or not. We found that our company disregards certain aspects of internal control condoned by COSO, while performing better on other dimensions.
Bakom stängda dörrar ? Svenska börsbolags redovisning av upplysningskrav enligt IFRS 7 Finansiella Instrument: Upplysningar : En kvantitativ studie av årsredovisningar för år 2007 och år 2010 från bolag noterade på OMX Nordic Exchange Stockholm Large
Bakgrund: Krav på ökad information och transparens i årsredovisningar har varit ett debatterat ämne de senaste åren. International Financial Reporting Standard (IFRS) har uppmärksammats med anledning av de ökad krav på upplysningar som standarden ställer däribland genom reglerna i IFRS 7 Finansiella Instrument: Upplysningar. Användandet av IFRS 7 blev lag år 2007 och gäller vid upprättande av en koncernredovisning. Kraven i IFRS 7 syftar till att visa företags hantering av finansiella instrument och därmed öka redovisningens transparens. Med anledning av de ökade krav som ställs på företag vill denna studie se hur noterade bolag har anpassat och förändrat sin redovisning enligt standarden. Syfte: Studiens syfte är att analysera bolag noterade på OMX Nordic Exchange Stockholm Large Cap och deras redovisning enligt IFRS 7 för att se om någon förändring skett i mängden upplysningar som lämnats i årsredovisningar för år 2010 jämfört med år 2007.Metod: Den kvantitativa metoden har använts för att genomföra undersökningen.
Sex skogsägares upplevelser av stormen Gudrun: en expolrativ studie
In Sweden we are spared from large natural disasters. However, in January 2005 part of Sweden was struck by a hurricane. It did not only leave a decimated landscape in its wake.

Uppfödning av slaktgrisar (Sus scrofa domestica) i stora grupper : gruppstorlekens betydelse för grisars välfärd och produktionsresultat
This literature study deals with the pig industry and how group size and available floor area affects the animal welfare and the production results. It shows that both the pigs? welfare and production result can be affected negatively if the environment seems stressful for the pigs, and if they are housed in a narrow area. If the pigs are being exposed to either physiological or psychological stress factors their immune system can be decreased and the growth can be impaired. Influence by the social status of the pigs is also reviewed.
Statistisk analys av partiella urladdningar
This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.
Att skapa kunskap i informationshavet : Om hur text kan struktureras för att skapa lärande i intranät
Creating instructions is not just about words, but also about text structure. A company creates many instructions to document their management systems, which often are presented through an intranet. This study examines how the text can be presented to make content understandable and give employees the knowledge to take action. An interview survey was made at Skanska Sweden and their management system "Vårt sätt att arbeta". The results show that it is mainly about creating an overview of the system and creating separations between different text sections.

Malmös digitala klyfta
Differences between groups or individuals in a society with regards to access to information and communication technologies (ICTs) are known as the digital divide. The digital divide pertains to differences in physical access to computers and the Internet as well as knowledgein using technology. Important factors affecting the digital divide are disabilities, age, gender, socioeconomical background, ethnicity and geography. The digital divide appears on several levels: internationally, nationally, regionally and locally. Individuals who, for some reason, have limited or no access to information and communication technologies risk, among other things, to experience social exclusion.
Natur- och miljöarbete inom förskolan : en jämförande studie om två förskolors arbetssätt
Teaching preschool children about the environment. A comparative study of how two preschools work with environmental issues.My investigations are based on qualitative interviews and observations carried out at two preschools, one of which has a nature and environment profile while the other works in traditional ways with these questions. I sought to explore the ways in which pedagogues in each preschool raise environmental awareness and, more generally, awaken an interest in nature in the children. The consequences of methodological similarities and differences will be considered.This term paper concludes that the difference between an environmental profile preschool and a traditional preschool working on environmental awareness is not large. The knowledge gained by children in the latter preschool surpassed that gained in the former.
Insamlingsorganisationer - vad förklarar omfattningen av redovisningsprinciper?
The natural disasters of recent time have caused the people of Sweden to donate very large amounts of money to different fundraising organizations. With this in mind, we found it interesting to examine the extent of disclosure in the annual reports of the Swedish fundraising organizations. Thus, the purpose of this study is to identify which factors that influences the extent of disclosure of accounting principles in the annual reports of Swedish fundraising organizations. To fulfill this purpose we conducted a content analysis of 149 annual reports from Swedish fundraising organizations. To help us explain the levels of disclosure we applied stakeholder theory, institutional theory and legitimacy theory.
Experimentell studie av sensationen hos färger
There are a large number of studies on colour and its influence on human feelings, but thereare only a few studies on the association between feelings and colour combinations. Thisstudie investigates the association between colour combinations consisting of three equallysized colours and the feelings they convey. The methodology used in this studie follows theinstructions from the Nippon Colour & Design Research Institute (NCD) in Japan, NCD havestudied consumer psychology towards colour and colour combinations for several decades.This study used semantically differential scales to evaluate existing colour combinations fromNCD to descriptive adjectives and creation of new colour combinations to explore therelationship between colour combinations and conveyed feelings. A total of 69 peopleparticipated in the tests. The main conclusions formed by this study are: (1) the feelingsconnected with the colour combinations differ partly between the Swedish population and theNCD and (2) the Swedish population have similar feeling associations to most colourcombinations, except for trend dependent adjectives such asmodern, cool etc.
SUNET-satsningen på folkbiblioteken - en kartläggning av argumenteringen för och emot en anslutning
The purpose of this study is to analyse the offer from the ministry of education and cultural affairs to Swedish public libraries concerning a computerised connection to SUNET (the Swedish University Network). The study is based on analyses of the main texts from the campaign and interviews in order to identify arguments that caused the libraries to accept or decline the offer. My conclusions are that the marketing of the SUNET-offer was to a large extent filled with technicalities, and that the campaign failed to identify and focus on the true recipients the decision-makers. The wordings used in the written material were too negative and discouraging. In order to succeed with future concentrations concerning public libraries, it is vitally important to overcome the boundaries between the decision-makers in the local government, the people responsible for information technology and the library staff..
