Utvärdering av den gröna smileyn inom livsmedelsinspektion : En intervju och enkätstudie i Halmstads kommun
With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.
Skolbibliotek och jämställdhet. En intervjustudie på ett mindre antal skolbibliotek
This thesis investigates gender equality at a few Swedish elementary school libraries, and how school librarians at these libraries work with gender equality issues. It is a semi-structured interview study conducted with staff at seven elementary school libraries. Several policy documents state that the school should be a gender-equal environment, but previous research shows that there is still a lack of gender equality, and that staff often treat boys and girls differently. It also shows that boys and girls are often portrayed in a gender-stereotypical way in children?s literature.
Quantitative thermal perception thresholds, comparison between methods
Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).
?På resande fot? - En studie om hur individer stöds och upplever mobilitet i sitt yrkesliv
The use of information technology (IT) has expanded to be available in large parts of the society.With reference to this mobility has become an increasingly used term, which reflects changes in our lifestyle, travelling and mobile artefacts. The technology development that has occurred in recent decades has made it possible for people today to be more mobile than before as they no longer are tied to a fixed workplace. Mobility has changed the ways to lead, coordinate andmeasure work productivity in organizations. It has also added new ways of working. The mobile development also means more challenges and changes in today?s modern organizations.The purpose of this paper is to analyse how employees in a consulting form use mobile technology in a work context, how they interact with others and how individuals reason about mobility.
Piotroskis F-score : En Grundläggande modell för värdering av aktier
När man väljer att analysera företag, finns det flera olika värderingsmodeller att använda.En av dessa är Piotroskis F-score. Denna modell har mestadels tidigare använts för att analysera företag på den amerikanska marknaden. Nu vill författarna undersöka hur tillämpbar modellen är på den svenska aktiemarknaden och dessutom kombinera denna modell med en Magic Sixes värdering för att öka dess precision.Syftet med denna studie är att undersöka om F-score i samarbete med Magic Sixes kan generera överavkastning och överträffa den svenska aktiemarknaden.Författarna har genomfört en kvantitativ studie med en deduktiv ansats. Data har samlats in med hjälp av databasen Orbis och Dagens Industri. Författarna har upprättat identiska listor för att beräkna företagens F-score och Magic Sixes.

Public WLAN - The interaction between venues and WISPs
Purpose: The purpose is to research different co-operations between venue owners and WISPs, when WLAN is deployed in a public space. The aim is to establish viable business models for the interaction between the two vital actors in the public WLAN industry. In this work, the advantages and disadvantages of revenue and cost sharing will be defined, along with technical and commercial issues that need to be resolved. Methodology: A number of case studies of the current situation have been conducted in the most attractive venues for WLAN, airports. As the public WLAN market had most widespread adoption and is most mature in the USA, case airports were chosen both there and in Scandinavia.
Hopp på Täby Galopp : svensk hindersport ur ett strategiskt marknadsföringsperspektiv
Horseracing is frequently referred to as the engine behind all horse activity in Sweden and it can be divided in to two main branches: harness racing and thoroughbred racing (HNS, 2008). Jump racing is a part of the thoroughbred racing and the jump racing is characterised by jumps on the racing track. Jump racing has been a part of the Swedish horseracing for over hundred years, but it has in recent years suffered from low economic profitability and been threatened by discontinuance (ATG & SG, 2008). Svensk Galopp, who is governing the horseracing in Sweden, has decided to increase the importance of jump racing. A workgroup was created for this purpose, and as a result of their work a strategy for the jump racing is supposed to be delivered in April 2009 (pers.
Aktielån : En studie av den svenska aktielånemarknadens utveckling
Stock lending is primarily a professional activity. The supply of stocks in the lending market comes mainly from pension funds and insurance companies, while intermediaries provide valuable services by taking positions as borrowers as well as lenders. Borrowers use stock lending for various reasons. For instance, hedge funds usually borrow stocks to cover a short position. There has been a lot of controversy in the stock lending industry and the debate has mainly concerned its effects for the stock markets.

Studie av planerings- och produktionsprocess i sågverksbranschen
The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.
Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk
The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.
