The aim of this thesis is to analyze children?s picture books regarding whether and in what form gender stereotypes can be seen in these. The purpose is also to evaluate whether the findings correlate to the different regulatory documents libraries have to abide to.       The study comprises five books, who are part of a selection of books especially chosen by Uppsala City Library to be used by primary school children aged 6-9. The method used is the study of text as well as illustrations, as the theory of this thesis is that the two cannot be separated, but has to be seen a unit. Other theories used in the analysis include Nikolajeva?s schedule of male/female properties and theories on gender.      The result of the study shows that gender stereotypes are in majority regarding the characters in the books, but that the opposite also exists.

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

This master thesis was made to investigate the possibilities of using the Matlab-basedsoftware Basegrain to determine grain size distributions of erosion protections onhydropower dams. Basegrain is a photogrammetric tool developed to generate grainsize distributions and other information about coarse flood sediments by analyzing adigital photo of the stone bed. The investigation was made by validating the ability forBasegrain to assess grain size distributions of various materials smaller than the blocksused in an erosion protection by comparing sieving results or manual measurementswith the results obtained by the program. A statistical comparison was then made bycomparing the results from sieving and the program. The possibilities of using thesame method on existing hydropower dams were then investigated by determiningwhether the method was practically viable or not.The results showed that Basegrain generated grain size distributions for coarse gravelthat were very close to the sieving results.

This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

This thesis examines the retrieval effectiveness of two Web search engines. The two search engines are chosen to represent two different types Google as a broad general search engine and Dogpile as a broad general metasearcher. Twenty queries have been used and the first twenty hits for each query were evaluated for relevance. The queries were invented by the authors, based upon their interests and information needs. They were expressed in a general manner, by using one or several keywords, in accordance with the simple search mode available for each search engine.

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

The purpose of this study was to examine the leadership style that is preferred by the employees from a psychosocial- and productive perspective. The study is based on Lewin et al´s research on the three leadership styles authoritarian, democratic and laissez-faire leader. This is a quantitative study with a questionnaires as data collection method. The sample consisted of individuals working in a municipality in one nursing unit. The data from the survey were analyzed by three separate one-way depending ANOVA in IBM statistics SPSS 22.

There are many kinds of joint operations and combinations of combined arms. This thesis puts its focus on Close Air Support, CAS. Throughout history there have been several cases of success, regarding these kinds of operations, but also failure. Much can be taught from organizational behaviour studies, applied on these military organisations in their cooperation with each other. The purpose of this thesis is to analyze the cooperation between the Swedish army and air force to determine the functionality of their process.

This study was made for the Swedish forest company Sveaskog because the sawmills they delivered timber to had noticed a high frequency of bucking splits in their products. Coworker Jim Edström at Sveaskog also wanted to know if there was a big difference between different felling heads. The purpose with this study has been to find out the amount of bucking splits and if there is any felling head brand that did a bigger damage that the others. The study was made in two steps, where the first part was a literary review to find out results and conclusions in earlier studies. The best measuring method to check bucking splits was the known ?trissmetoden?.

This thesis has been performed at the system development company Verendus System AB, together with the home care company Basic Care Unit (BCU).The thesis has consisted of developing a web based informationsystem for BCU in which they can administrate their business. At the time of writing this thesis, BCU was using a windows-application to administrate their activities, which was both costly aswell as resulting in an unnecessary burden. The aim the thesis has thus been to create a platform-independent information system that simplifies and streamlines BCUs work by being user-friendly aswell as imposing some simplifying features.The students has been developing the system by the help of a work method they themselves developed. The method consisted of working in several iterations that each had several milestones. The method resulted in the students knowing easily when each iteration was finished or not.The thesis resulted in a working platform independent prototype.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.
