?Vissa kan man lita på mer än andra? . En studie i gymnasieelevers källkritiska bedömningar

The main purpose of this master thesis is to examine how high school students think when they independently are evaluating information for a school assignment. We examine what types of sources they use, and what their reasons are. Besides that we also examine what sorts of criteria they use when evaluating if a source is usable, and if there are any other factors that can have an influence for their choice of material. We have done a qualitative study with 23 students, where the students wrote down their answers in a questionnaire containing wide open questions. We have created our own tool for analysing the material by extracting the most general things in our chapter of earlier research, concerning the three questions which our study is based on.

Användarutbildning på webben

User education is an important aspect of university libraries' service to its users. This Masters' Thesis is about online user education. The aim of this study is to analyse five Swedish online user courses in relation to information literacy and learning theory. The web-sites were explored through textual analyses to find how concepts of information literacy and learning theory are expressed. The theoretical framework is based on Carol C Kuhlthau's three levels of user education, Paul Ramsden's three theories of teaching in higher education and Christine Bruce's different aspects of information literacy.

Lek kring stol

The aim of this project was to develop a product which gives one or more objects of daily use an additional function. Thru the creativity of children the object shall transform into a new source for play for pre-school children.The purpose of this work was to research how fantasy and free play of children could be enhanced. I wanted to know how I can motivate children to use their fantasy transforming objects into new sources for play.This was achieved by means of developing a number of different prototypes which I tested in Kindergarden. My observations lead to the development of a cloth-wrap for the chair which provides the required source for ongoing role-play. The chair suddenly transforms into a new landscape and multi-purpose object where children?s fantasy is stimulated and creative play is supported..

P?m?rkning vid virkesberedning - Bastning. Ett hantverksf?rs?k

This essay aims to investigate a rare method of marking up timber before hewing it. The method for marking up timber is by eyesight, where visual judgment and the use of a broad axe are the tools employed. The broad axe is driven through the bark and exposes the inner bark in a straight line. The method is described by a craftsperson dating back to the 1930s. There is a lack of information regarding the method.

Investigation of tissue factor mRNA levels in human platelets using real-time PCR

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

Utvärdering av protesfötter med hjälp av en konstruktion som kan utföra en mekanisk gång.

This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is.

Uppnår sjuksköterskestudenter lärandemålen?

Objective: To see if nursing students believe that they have acquired the knowledge that the Higher Education Ordinance demand and if there is any difference between the theory learned at the University and the clinical reality in which students receive their practical training. Method: The method is quantitative and is divided into two parts, one in which the authors describe how the questionnaire was developed and how validity was strengthened. In the second part, the authors describe how the data analysis was made and how reliability of the result was strengthened. Result: The result shows that the students felt that they have achieved most of the objectives of learning demanded by the Higher Education Ordinance. But some objectives are perceived as not at all or only partly achieved.

Teststrategier och användning av testautomation : En studie utförd på företaget Extenda AB

In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.

Arkitekturhistorisk terminologi. Antikvariskt behov av kunskapsstöd

This study you are about to read have two investigated areas concerning the need ofsources in terms of architectural historys terminology. The investigation is based on aquestionnaire study.The first aim of this study is to describe the intergrated conservations professionalqualifications in the subject. In what condition are the knowledge of them who recentlypassed the examination, what needs do the professionals have, what kind of sources duthey use in fields and are they satisfied with the amount of sources?The second aim of the study is to find out if there are any place for developing a newsource at the market? If it is, how can a new source include the informed needs?The study came up with several needs pointed out by the professionals in the field.These needs are the groundwork of a new source that the study introduce, aarchitectural glossary of terms, made of illustrations! The point is that the new idea ofglossary will meet the needs of today, rationalise the work and improve the knowledge inthe subject..

Estetiska omdömens paradoxala natur : En jämförelse av Hume och Kant

This work is meant to contribute to the research of adaptation studies by focusing on a special case: the transformation of a fictional diary into a movie. In order to sustain the form of the literary source the adaptation to movie requires certain strategies. Först of all, the diary genre is characterized by a one-dimensional narration. Second, diaries only supply a few written dialogues, hence this "void" has to be compensated and filled by media specific measures. Third, the investigated diary is a story of individualization and emancipation of a single woman.

Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

Behovet av kommunikation om kommunikation - En fallstudie om intern kommunikation på ett folkbibliotek

The aim of this study is to gain knowledge about the internalcommunication at a public library in Sweden, focusing on the flow of information and the library employee?s role as a source and receiver. This is an important subject because internal communication affects not only the internal work, but also the users. Despite this there are few studies about internal communication in libraries. The research questions used are: How do the employees perceive the role as source of information, and what choices do they make before they spread information? How do the employees perceive the role as receiver of information? How do the employees feel that the information flow works in the organization as a whole?The research is founded on five qualitative semi-structured interviews with the library employees.

Fördelar och nackdelar med utematematik : Lärares, föräldrars och elevers inställning till arbetsformen

Aligning parallell terms in a parallell corpus can be done by aligning all words and phrases in the corpus and then performing term extraction on the aligned set of word pairs. Alternatively, term extraction in the source and target text can be made separately and then the resulting term candidates can be aligned, forming aligned parallell terms. This thesis describes an implementation of a word aligner that is applied on extracted term candidates in both the source and the target texts. The term aligner uses statistical measures, the tool Giza++ and heuristics in the search for alignments. The evaluation reveals that the best results are obtained when the term alignment relies heavily on the Giza++ tool and Levenshtein heuristic..

Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
