Bland mumier och mosslik - en jämförande studie av populärarkeologi och fackarkeologi
In my paper I have compared popular science and neutral science regarding language and construction. My task was to find out if there are differences between the language of popular science and that of scientific science. The purpose of my paper is to answer four questions1.How do the authors present the bogbodies and the mummies in the two categories?2.What does the popular science imagine that you want to read about?3.Is there a difference between the target groups of the two categories?4. Does the presentation of the subject have consequenses when it comes to contents and readers?I have studied how often the authors use drawings, photos, diagrams, maps, and if the titles of the chapters can tell you something about the nature of books.
Bostadsbidrag och arbetsutbud : En studie av ytbegränsningen som infördes i 1997 års reform av bostadsbidraget
I 1997 års reform av bostadbidraget infördes en begränsning av den bidragsgrundande boytan. Denna studie undersöker effekterna på inkomst från arbete av denna ändring, med syfte att svara på frågan om en minskning i bostadsbidrag leder till att man väljer att öka sitt arbetsutbud. Analysen görs med hjälp av en difference-in-differences-skattning och slutsaten är att det inte fanns några signifikanta effekter på inkomsten från arbete, vilket innebär att det inte går att påvisa att ytbegränsningen påverkade arbetsutbudet..
Tryckalgometri hos friska hästar :
There are no reliable, objective and simple methods today for measuring pain in horses. The purpose of this study was to evaluate and describe measuring of mechanical nociceptive threshold (MNT) values with a pressure algometer in clinically pain free riding horses at the riding school of Strömsholm. In this study there were 24 horses. Tape recording and electromyelografi (EMG) was used in an attempt to increase objectivity in the examination. MNT increased with age, however sex and colour had no influence.

Sociala intranät - ett intranät för alla? : Uppfattningar bland leverantörer och beställare
A social intranet is an information and communication channel that is relatively new. There is still a small amount of research done around social intranet and what it is, and also on what organizations and their members may benefit from using such an intranet. Therefore, this paper was written with the purpose to em-phasize the reasons, possibilities and difficulties of implementing and using a so-cial intranet. With interview as method we took part of the experiences and views on social intranet from a number of organizations that are using or is about to establish a social intranet, and also from companies who deliver the service. Through the use of previous research in organizational communication, we then analysed the responses we received from our respondents.
Jämförelse mellan två olika plastningsprinciper, Cross Pac kontra konventionell plastning :
Baled silage has become one of the most important conservation methods in Sweden. Because
we take our grass as silage we get the quality and the good hygenic that we would like to
have. Silage has become a big buisiness also in the horse feeding where many of the breeders
have changed from the hay to the hay-silage. The difference between regular silage and haysilage
is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands
on machinery and wrapping material since the grass gets sharper and harder to press together
real hard.
The main reason for the test was to compare two different systems for wrapping, the new
Cross Pac and conventional.
Locally produced pork ? Västra Götaland
The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed.
Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.

Riskkapitalbolags styrning av portföljbolag i USA, Europa och Kina - En komparativ fallstudie
This thesis studies private equity firms' implementation of management control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).
Religionens många ansikten : En undersökning av skillnaderna i undervisningarna av kristendom inom syrisk-ortodoxa kyrkor och svenska skolor samt hur skillnaderna påverkar de syrisk-ortodoxa ungdomarna.
Religious education in Swedish schools aims to be as objective and non-confessional as possible. This sort of education can lead to that the different religions are presented in a way which is unfamiliar to the followers of the different religions. This problem is what I have focused on in this essay since I myself was a victim of a similar situation. As a syriac-orthodox youth I felt that my Christianity was not the same as the one presented in school. I felt that it had nothing in common with what I learned in my church, therefore I asked myself the question: Whose Christianity is being represented? Therefore I have focused on the syriac-orthodox church in this research.The purpose of my essay was to enlighten the differences between religious education in syriac-orthodox churches and Swedish community schools.
