Åh, det här klarar jag! : Samtalets betydelse för matematikförståelse
The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.
Balanserade styrkort i statliga organisationer - Om, hur och betydelse?
AbstractBachelor thesis G3 in Business Administration, Linnaeus University School of Businessand Economics, Financial Control, 2FE90E, Spring Semester 2010Authors: Kennerth Eriksson and Leo H KochAdvisor: Lars-Göran AidemarkTitle: Balanced Scorecard in governmental organizations ? About, how and its meaning.Background: The Balanced Scorecard is a Control System that includes both financial andnon-financial measures which intend to link the short-term business management with the long term vision and strategy. Businesses in the public sectors are different fromthe private sector on several levels and they often seek to reach multiple targets.Therefore, their choice of Control System becomes interesting. According to the SwedishNational Financial Management Authority (Ekonomistyrningsverket) among others, thereis no clear knowledge of how widespread the Balanced Scorecard is in governmentalorganizations. The lack of that knowledge is one of the questions at issue with this thesis.Is it only a few organizations that are using the Balanced Scorecard or parts of the model?Another question at issue is about how the Balanced Scorecard is used in the point ofcontrolling in the organizations we chose to investigate further.Purpose: The purpose of this thesis is partly to investigate the existence and use of theBalanced Scorecard in governmental organizations and partly to describe the design ofthe Balanced Scorecard in the studied organizations and explain why they have chosen towork with the Balanced Scorecard and what impact it has on them.Demarcation: The first part of this study has been demarked to only look at the existenceof the Balanced Scorecard in governmental organizations.
Hur designar man en e-handelssite: : är designers och dokumenterad forskning överens?

Our approach consists of two phases. First we comprise relevant research within the target area. This is then divided into logical themes and is used as a foundation for an interview guide, which will be used in the second phase. After this, in the second phase, we conduct qualitative interviews with designers that are actively working with design of e--?commerce sites.
Bilden av förskolan genom bilderboken : En studie om hur förskolan skildras i åtta bilderböcker
The goal with this essay is to determine if the image of preschool, in a specified number of picture books, is consistent with the posted goals of the preschool operations in the curriculum of preschool published in 1998 (hereafter Lpfö 98). Besides that the essay is also planned to look at how the preschool?s status have changed after Lpfö 98 was established and if this is shown in the picture books. Therefore this essay will focus on picture books published 1998-2009 because after that a new version of Lpfö 98 was published. Also the picture books chosen for this study are all stories about preschool or kindergarten.The questions that this essay will answer are: How are the activities in preschool described, and how do they match the guidelines in Lpfö 98? In what way has the status of preschool been affected since Lpfö 98 was published? In what way has the teachers? role been affected and how is that shown?In order to answer these questions I will use a quality text analysis of picture books for children.
Effekt av värmemadrass efter ECC-inducerad hypotermi vid hjärtkirurgi : -En kvasiexperimentell pilotstudie
Bakgrund: Vid hjärtkirurgi kyls patienten via ECC (extracorporeal circulation) till 32-34 °C för att minska metabolismen och syrekonsumtionen i vävnaderna. Efter att operationen är klar är det viktigt patienten blir normoterm då hypotermi medför många negativa effekter.Syfte: Att undersöka om värmemadrassen Inditherm Alpha® hjälper patienten att hålla en normal kroppstemperatur efter ECC-avslut samt om andra faktorer, dels demografiska, dels procedurrelaterade, kan påverka utfallet av uppmätt kroppstemperatur.Metod: Femtiofem patienter som genomgick elektiv CABG och/eller klaffoperation med ECC-inducerad hypotermi inkluderades konsekutivt. Undersökningsgruppen (n=29) genomgick kirurgi med värmemadrassen Inditherm Alpha® medan jämförelsegruppen (n=26) genomgick kirurgi utan värmemadrass. Grupperna var jämnt fördelade i alla avseenden förutom kön.Resultat: Flertalet patienter sjönk i kroppstemperatur efter ECC-avslut (p < 0,0001) men majoriteten av patienterna var normoterma vid ankomst till intensivvårdsavdelningen. Undersökningsgruppen hade inte högre kroppstemperatur vid något mättillfälle jämfört med jämförelsegruppen.
Målsättning, prognostisering och resursfördelning i en budgetstyrd bank respektive budgetlös bank: En fallstudie av två svenska banker på kontorsnivå
Speaking of budget and budgeting is almost as adding fuel to the fire. The subject evokes a lot of emotions, both positive and negative. Some might consider budgets as a bureaucratic process that won?t lead to any good. Others might find budgets as extremely helpful and necessary in a company?s planning process.
Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys
People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS.

Gerillaodling - ett frö till förändring
Abstract A phenomenon that has been noticed more and more in media and the public space in recent years is what is called guerrilla gardening. It means the illicit cultivation of someone else?s land. This report's intention is to analyze what impact guerrilla gardening could have on today's urban space in terms of stable changes in norms and physical design. I have also focused on guerrilla gardener?s choice to carry out these actions illegally, without asking for permission, and what impact that could have on the issue of appropriating public space.
Instrumentbordets sterilitet
Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
The Scientific Coach - Idrottsforskning i tränares vardag
Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008). This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.
e-infrastruktur som stöd för hemtjänsten
The annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.
