Miljöarkeologi i Umeå stads hamn och slagfältsarkeologi på Krutbrånet : Två fallstudier inom historisk arkeologi i Umeås 1800-tal

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.

Passage Retrieval: en litteraturstudie av ett forskningsområde inom information retrieval

The aim of this thesis is to describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How well do the approaches work in experimental information retrieval (IR)? PR is a research topic in information retrieval, which instead of retrieving the fulltext of documents, that can lead to information overload for the user, tries to retrieve the most relevant passages in the documents. This technique was investigated studying a number of central articles in the research field. PR can be divided into three different types of approaches based on the segmentation of the documents.

Publika private equity-bolags påverkan på styrningen av sina portföljföretag. En fallstudie av styrmekanismernas utveckling under ägarperioden.

Recent years have been very turbulent for most private equity firms. Especially the financial meltdown in global economy has affected the industry, but also the public pressure has made private equity houses change their control strategies towards more conventional methods used in public companies. This thesis aims to put light on the control methods used in listed private equity houses which use a buyout strategy. The paper describes how the control methods change over the different phases the asset experience and how different value generating strategies use altered control methods. Using Merchant's (2003) framework for management control systems and Berg and Gottschalg's (2004) research on value generating strategies in buyouts the thesis shows that action controls as designing instructions for the board and a business plan, together with goal alignment is the commonly used control strategy directly after the acquisition.

Kromatografi av polära läkemedel och metaboliter med HILIC-teknik

The purpose of this project was to investigate if retention of polar compounds that are given to treat tuberculosis, diabetes, inflammatory bowel disease and childhood leukemia could be obtained with HILIC separation. By varying different parameters for different types of columns the compounds were analyzed with the aim of finding guidelines for future method optimizations. To perform these analyzes three different columns were tested ? ZIC-HILIC (silica-based with zwitterions), ZIC-pHILIC (polymer-based with zwitterions) and XBridge Amide (amide functions). The results were evaluated with selected quality measures.

Varför tvivlar jag? : En essä om att omsätta vetenskapliga teorier med praktisk kunskap

This essay is about the development process I have undergone during my experience-based preschool teacher education. I write about my internal process, about how I as a childcare worker go from assertiveness and believing in myself into fighting doubts, thoughts and feelings as a preschool teacher. The purpose with this essay is to make the difficulties with managing new knowledge and practicing it in real life visible, and at the same time overcome your uncertainty in a new professional role. The essay is based on two stories from my professional life where I, in the first one portray my actions and behavior as a childcare worker and in the second one as a preschool teacher. Based on my stories I try to answer questions as what does the individual learning process look like when going from one professional role to another in the same profession? What impact does theoretical knowledge have on practical knowledge?I have used reflection and writing as methods for my paper.

A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

En undersökning av framtidametoder för att säkra förband i produktion

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

3In the last couple of decades there has not happened much inthe ?farriery?- department. The work procedure, methods andfarrier´s tools have stayed the same over time, which have ledto a huge workload that is wearing the active participants out.So think if you were able to ease the working process of horseshoeingfor a farrier. The farriery is still first and foremost aprofession based on handicraft that has to relay on the farrier´sgood memory, sight and sense. The workplaces for a farrieris most of the time at the hiring horse owner`s stables, whichmakes it harder for the farrier´s to have influence over theirworking situation.

Mitt Komponerande, Kreativitet Och Teknik : Självstudie av den egna kompositionsprocessen

This essay describes a single case self-study of a music composer in order to track the compositional process in real time. In the study the subject and the researcher are the same person. The study builds on previous empirical studies that have used methodological approaches such as analysis of computer-based digital data collection, verbal protocol and video observations. It deals with issues of the compositional process related to for example time consumption, number of artistic decisions, the different roles and skills of a music composer, and methods of research in the musical composition process. During three shifts the researcher worked as a music composer dealing with the issue of converting an audio sketch of a composition into a representative finished audio product.

Kunskapsdiagnos i matematik ? något att räkna med? : En kvalitativ studie av lärares och rektorers tankar kring kunskapsdiagnos i de tidiga åren.

Syftet med studien är att belysa lärares och rektorers tankar kring diagnostisering av elever i de tidiga skolåren vid användande av Skolverkets diagnosmaterialDiamant, som riktar in sig på den förberedande aritmetiken.Studien har en kvalitativ ansats med semistrukturerad intevju som metod. Deltagarna i undersökningen är fyra lärare samt två rektorer med erfarenhet och utbildningen inom området.Resultatet visar att informanterna anser att de får betydelsefull information om var barnen befinner sig i den grundläggande taluppfattningen via diagnosen och därmed kan barn med behov av hjälp och stöd uppmärksammas. Informanterna har en formativ syn på diagnostisering. De fokuserar på hur resultatet följs upp, hur de finner pedagogiska och organisatoriska lösningar. Rutiner för detta är olika på de enheter där informanterna är verksamma.
