Läsutveckling utifrån ett sociokulturellt och mångkulturellt perspektiv

The purpose of this investigation is to compare the teaching in reading of three pedagogues in form 2 in three different schools from a second language perspective. Among other things it implies to investigate how the pedagogues think of teaching in reading and the reading field to be compared with if these fields are adjusted to a diverse cultural perspective. This investigation is carried out through observations and interviews. To compare the schools they have been picked out from the number of pupils and the number of second language pupils, that is 15 %, 67 % and 95%. The investigation also includes how the pedagogues weigh the pros and cons within reading and working methods.The further reading is built upon theories and previous research that have an attachment to the view of the sociocultural and the diverse cultural perspectives of teaching.

Statistiska metoder för härledning av indata till säkerhetsanalyser inom kärnkraftsområdet

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

EN JÄMFÖRELSESTUDIE AV PLAST- OCH GLASHEMOCYTOMETRAR FÖR BERÄKNING AV BLODCELLER I VENÖST OCH KAPILLÄRT HELBLOD

Hematology-instruments that analyze blood cells can at specific cases be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.

Relationship between moose (Alces alces) home range size and crossing wildlife fences

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

Spelar geografi roll? : En studie av Bolognaprocessen ur ett policy transferperspektiv

AbstractDoes Geography Matter? A Study of the Bologna Process from a Policy Transfer Perspective.Essay in Political Science (D-level) at Karlstad?s University by Beatrice Högå, Spring 2007Tutor: Susan MartonThe purpose of this essay is to generally see how theories of policy transfer can help us to better understand the process through which the Bologna Process is being spread throughout Europe, and to specially see if geographic placement, i.e. in the heart of Europe, plays a role in how well and how fast the Bologna Process is implemented.To be able to answer the purpose, I have used Evans and Davies theoretical model on policy transfer network to describe the Bologna Process. Furthermore, Sweden and France are the countries being examined when they differ on the independent variable. From there, I have applied an analytical tool, namely process tracing, to examine whether there are differences in the two countries? work with the implementation of the Bologna Process.I have designed six specific research questions:Have France performed more extensive work than Sweden when it comes to implement the two-cycle system?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to recognize awards and periods of study?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to quality assurance?Have France performed this work earlier?After applying the analytical tool to be able to answers these research questions, the answer to the general question Does geographic placement, i.e.

Den sämsta målgruppen att lura? : En studie av unga nyhetskonsumenters attityder till native advertising

With the increased volume of commercial content online, some news sites have adopted so-called native advertising on their websites to convey marketing messages more discreetly. As an increased share of advertising budgets is spent on this form of advertising this essay aims to examine its news consumer?s attitudes towards the phenomenon. The research was carried out through a qualitative study where news consumers discussed their attitudes in two separate focus groups. This was analyzed with the help of the previous studies Advertisement - an uninvited guest? and Banner Blindness as well as theories including theory of science hermeneutics, reception analysis, convergence culture, brand schema, advertising schema and ad- brand attitude.The results show that in most cases native advertising is met with indifferent attitudes but in some cases also confusion, which could lead to negative attitudes towards the ad and the news site.

Från skilda världar till "Valet är ditt! Inte maktens!" : En analys av Aftonbladets debatt- och insändarsidor 1999 till 2005

AbstractPurpose/Aim: To investigate how the positions between the paper, the public and the elite in society have changed on Aftonbladets Op-Eds and Letter to the editor-pages between 1999 to 2005. In a wider context this means Aftonbladets potential to contribute to the role of the press as a forum of public debate.Material/Method: The study focuses on one week during 1999, 2002 and 2005. Here a quantitative contents analyse with inspiration from conversation (dialogue) analyse has been used.Main results: The study shows that the paper has strengthened its position over this period of time. Mainly by taking a more active role in forming and encouraging the debate. The public was given more space in 2002, then in 1999 and 2005.

Pelletering av tallspån : grundläggande studier

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

3D-byggnadsmodeller utifrån takkonstruktioner : Lagring, hantering och bearbetning

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

Den allvarsamma leken : Om källan till mening i arbetet

Based on 30 years of work experience in TV and film production, I have made a phenomenological analysis of my perception of meaning in work - how it arises and how it is undermined. The story starts in my experience of early professional film making in the 1980's and describes how a change to work in TV production required the development of a new professional identity. The text also illustrates how as a female director I have managed my role in a male dominated and structured work environment. Being defined as an exception from the male norm has pushed me towards femininist reflection and the need to redefine my own work role - the generally accepted view having felt uncomfortable. An analysis of structural change in TV and film production shows how market pressures and ways of thought have increasingly invaded cultural endeavour. Professional spheres of influence are weakened, while developments in the media are characterised by a commercialism which encroaches more and more upon artistic, spiritual and moral values. This attitude, where quality is in retreat, has transformedprogramme makers from creative originators into becoming suppliers of raw material in a factory- like process geared to produce great volume at low cost.The aim of this essay is to show how changes in society and in TV and film making have affected my perception of my work.

Marktillstånd och borbrist på åkermark planterad med gran i Västerbottens län :

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.

HemoCue Cognatus - Ett Intelligent Analysinstrument

HemoCue AB is a multinational corporation targeted on manufacturing point-of-care analysisinstruments for medical treatment. Their main product, the DM 201, is outdated and has bigissues gaining new market shares. For example, no medical treatment center in Sweden usesDM 201 frequently. The project of developing a new instrument to replace it was assignedtwo students at the development engineering program at Halmstad University. The projectalso included integration of the new platform for DM 202 to HemoCue AB:s remainingproducts.The project began by defining the different technical areas concerned.

Jätteträd ? inventering, bevaring, skötsel samt rekrytering :

During the summer of 2007 I was employed by Högestad Christinehofs Förvaltning AB. My main task was to make an inventory of giant trees at the estate. Högestad and Christinehof,which with their total possession of 13 000 ha of land is the biggest estate in Scania. A giant tree is a tree with a diameter in breast height more then 1 meter. Trees of these dimensions are registered by Swedish authorities. Landowners with a giant tree on their property can receive a subsidy for cutting trees that are in competition with the giant tree.(Levenskog, 2007) Giant trees are important for biodiversity in the landscape and there are important habitats for different insects, birds, bats, lichens and funguses.

Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden

Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.
