Varför digitalisera? En studie av tillkomsten av Kungl. bibliotekets digitaliserade samlingar

The Royal Library (KB) of Sweden harbours great collections of different objects through a special law from 1661. This master degree paper is exploring a part of KB?s digitisation of those collections. It deals with the questions about what the KB had chosen for digitisation, why those choices were maid and who is responsible for making these decisions. The paper will also for example seek out different patterns and trends in the information.

Neuro Muskulär Elektrisk Stimulering (NMES) som behandlingsmetod hos strokepatienter med droppfot

Stroke är en av våra stora folksjukdomar. Cirka 30 000 personer insjuknar årligen i Sverige. Många av dessa personer får även droppfot. Peroneusstimulering började användas för första gången 1961. Tekniken är nu generellt känd som Funktionell Elektrisk Stimulering (FES).

Strategies for Goodwill Allocation

Since 2005 all companies listed on a regulated stock exchange within the European Union are required to present their financial reports in accordance with International Financial Reporting Standards (IFRS) and International Accounting Standards (IAS). The purposes of these standards are to accomplish international harmonization of accounting rules to make financial reports more comparable. However, recent research has shown that some firms tend to use goodwill strategically in a business combination by manipulating the acquired assets and consciously allocate the intangible assets to goodwill to reduce the depreciation in the income and decrease costs. This phenomenon may reduce the comparability between financial reports and thus has an opposite effect on the purpose of IFRS and IAS.The aim of this study is to show how the companies involved in this study allocate goodwill strategically. Furthermore, the introduction of the new standards has contributed to that goodwill now is a subject for impairment test, therefore we want to show whether this affected the comparability of the companies in this study.An empirical study was conducted, based on interviews with four Swedish managers.

Mineralogisk och strukturell inverkan på fragmenteringsenergi och andel producerat finmaterial i en konkross

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Jämförande av Genesis Single och kliniska test : Muskelstyrka hos individer med tidigare ACL-skada

Inom sjukgymnastiken används mätning av muskelstyrka för att utvärdera och planera rehabiliteringsperioder. Isokinetiska dynamometrar och one repetition maximum (1RM) är två vanliga metoder för att mäta muskelstyrka. Efter en skada på främre korsbandet (ACL) sker en muskelatrofi av bland annat mm. quadriceps och hamstringsmuskulaturen och det är därför viktigt att kunna utvärdera dessa muskler. Genesis Single är en ny tränings- och utvärderingsmaskin på vilken inga tidigare studier gjorts.

"Jag bara tar ur skafferiet det som passar..." : En undersökning av hur lärare och barnbibliotekarier arbetar med skönlitteratur på lågstadiet

The aim of this thesis was to investigate the methods used by teachers and childrens' libra­rians concerning their work with fiction at the junior school level. Based on a series of qualitative interviews and by compiling a list of short summaries of literature relevant to our thesis we wished to reflect on the manner in which the respondents see themselves in their teaching roles.We also wanted to discover what problems they had in their work and what visions they held for the future. The methods used by the teachers were mainly: reading- both aloud and individually, process-oriented writing, use of fiction in thematic studies and dramatization. The teachers' aspirations for the future included a centrally situated school library and further education in children's literature. The teachers take the needs of their pupils as a starting point and build on these needs - using many years of literary teaching experience as a foundation."Booktalks" for the children and intermediaries (teachers ...)and education in books and library systems are the childrens' librarians main literaturepedagogic methods.

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.

Optimal högtalarplacering i en lastbilshytt

The project took place in Södertälje, Sweden, on behalf of Scania CV AB. The goal was to create a new listening environment in a truck cabinet.The results were accomplished by the performance of a few different tasks. First a benchmark was made on Scanias top competitors. Second a listening test was made to get an apprehension of what people find lacking in the sound reproduction of the sound system.

Nationella prov i NO : Verktyg för likvärdig bedömning eller dolda svenskaprov som diskriminerar?

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.

Har personer med ADHD en förhöjd prevalens av otrygg anknytning i jämförelse med normalbefolkningen? : En undersökning av anknytningsstilar i en population av ADHD

Studien ämnar undersöka om människor med ADHD uppvisar en högre prevalens av otrygg anknytning (enligt testet ASQ) än normalbefolkningen. Metoden som har använts för att mäta detta är en internetbaserad självskattningsenkät; Attachment Style Questionnaire, ASQ, som är ett test som mäter olika kateogier av relationella mönster baserade på anknytningsteori. Testresultatet indikerar en hög förekomst av otrygg anknytning (95 %) i den undersökta gruppen. Med tanke på begränsningar I validiteten främst på grund av endast användningen av enbart ett test för mätning och på grund av att ASQ mäter relationella aspekter i en individ så undersöker studien först och främst resultatet av relationella mönster i gruppen ADHD..

Utvärdering av snabbtest för ketonkroppsdetektion hos mjölkkor

För att en mjölkko ska vara vid god hälsa och producera optimalt är det viktigt att hennes energimetabolism är i god balans. Förhöjda nivåer av ketonkroppar (?-hydroxybutyrat, acetoacetat och aceton) är en indikation på att störningar i energibalansen föreligger och har i flera studier kopplats samman med ökad risk för sjukdomar och sänkt mjölkproduktion. I veterinär ambulatorisk verksamhet används olika snabbtester för att enkelt påvisa förhöjda nivåer av ketonkroppar i mjölk, urin och blod.Syftet med denna studie var att utvärdera fyra snabbtesters tillförlitlighet för ketonkroppsdetektion hos mjölkkor, under svenska förhållanden, i jämförelse med en verifierad laboratoriemetod.Från 51 mjölkkor i olika laktationsstadier samlades blod-, mjölk- och urinprov. Förekomsten av ketonkroppar undersöktes med fyra olika snabbtester: Precision Xceed (helblod), PortaBHB milk ketone test (mjölk), Acetontest (mjölk) samt Ketostix (urin).

Förskolepedagogers uppfattningar av sitt arbete kring energiomsättningen

The aim of this study is to examine the understanding, preschool teachers, have about their work related to energy conversion in the human body. Through individual interviews, answers have been sought to the following questions: What do the preschool teachers believe they need to know about the link between food and energy? What are the different methods preschool teachers use to workwith the area of energy conversion in the human body?The results show that preschool teachers have knowledge in terms of food and its nutrients as an energy source for the body to cope with. However the more thorough and detailed questions become all the more uncertainty there is about the topic. Preschool teachers on their own initiative do bring up the topic with the children and begin conversations as well as ask questions, perform experiments and demonstrations.

Stress: En gransking av studenters stressnivå - Praktik och icke praktik

Practical and theoretical learning are methods that are used in schools as a way to prepare students for the working life. Within the practical learning knowledge is not only acquired to learn in practice, but the students must also be able to apply their theoretical knowledge to what he/she does. Against this background, the aim of the study was to investigate the importance of practical learning for students in college / university level and how they are experiencing the stress that may arise out of the loss of practical learning during their education, as well as their vision for working life after completing their education. The population of the study consisted of N = 36, which 18 of these had used both practical and theoretical learning and the remainder had only used theoretical learning. The method was a questionnaire survey with a high proportion of fixed alternative answers according to likert scales.

Hur arbetar lärare med laborativ matematik? : En kvalitativ studie om hur fyra lärare arbetar främstmed avseende på laborativa inslag i undervisningen igrundskolan

The objective of this research is to unveil how respective teacher consider about the laboratory working methods in mathematics. The research even includes answers to questions such as, what approaches and attitudes the teachers have and the methods they use when instructing their students when teaching mathematics, what the materials used by the teachers are and how important working creatively is to help the students develop their logical thinking. I also looked into issues that can help understand how and why teachers use laboratory mathematics for students in young ages. As a conclusion the research showed that the teachers aim to the goal that includes helping the students understand mathematics, strengthen their logical thinking and creativity.In the method section qualitative data was used, which contained four interviews with different pedagogues that daily interact with students in elementary school. The reasons for using the method of qualitative data was to help me deeper understand and answer the specific questions I had to the pedagogues and to even compare how different pedagogues differ in their approaches and methods.
