Outsourcing- vilka faktorer påverkar intressenternas förväntningar? En studie om ett förändringsarbete mellan flera intressenter i ett outsourcing sammanhang
The complex, ever growing and changing environment, requires that today's organizations are dynamic and willing to change in order to stand competitive.This awareness has made change number one priority in almost all organizations' agenda.We live in a world that is constantly changing, yet many organizations fail to change successfully. When a change occurs in complex environments with multiple stakeholders, it immediately increases the complexity and the challenges of the change process.A complex situation may arise when, for example, partial outsourcing of the corporate information system infrastructure. Two of the most difficult challenges that organizations face today is to conduct a successful change process and managing the effect of a change, such as arising expectations. It is very common for change in an organization not to achieve the desired result or that they even fail. There may be a lot of reasons for these failures.
Prediktion av beta för fonder
SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
När psykiatrin vände sig åt samhället : Om psykiatridebatt, sektoriseringsplaner och Nackaprojektet 1968-81
This essay revolves around the reformation and sectorization of Swedish psychiatry starting in the 1970?s. Psychiatry was to change from being based in closed asylums to being an institution in the middle of society, finding social solutions to mental illness and working through a dynamic network of various care givers, such as welfare officers, nurses and psychiatrists. This new kind of psychiatry was first tested in Nacka, where psychiatric reformers Johan Cullberg and Bengt Berggren were the heads of a six-year long pioneer project of sectorized psychiatric care. My specific purpose is to analyze the new ideas of mental illness and of psychiatry?s role in society which were introduced in this project and how they were expressed in the official reports presenting it.The reformation was preceded by a public debate concerning psychiatry, which had intensified a few years around 1970.
Smart konsumtion : unga vuxnas attityd till miljö- och rättvisemärkta produkter
We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.
Faktoranalys av EU: s strukturella indikatorer
This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

"In i sagans land" : Aktionsforskning i bibliotekspraktiken med syfte att utveckla sagostunden
The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.
Strävan efter det legitima polisväsendet : En jämförande studie mellan tre postkonfliktländer
Products and services have for a long time competed with their brands. For some time now, cities have begun to compete with each other to attract visitors and other stakeholders to come to their town. It is important that the citizens feel as they are a part of the message that the city sends out in its communication.Cities are today working actively with their brands, much like regular companies, in order to create the profile and image in order to be competitive against other cities and places. Cities and places are part of a dynamic process which includes both positive and negative events. These events might have an impact on the brands, and therefore it is a necessity to be able to react on these events to make the most of positive things and deal with the negative in a way that minimizes the effects on the brand.Citybranding as a research field is quite new.
Flödesoptimering av GROT-flis med beslutsstödet BioMax
Sönderdelning och transport av GROT (grenar och toppar) kräver dyra maskinsystem samtidigt som efterfrågan av sortimenteten varierar kraftigt under året. Det är därför svårt att planera flöden av GROT-flis effektivt och samtidigt välja rätt maskinsystem.
AB Karl Hedin är en sågverkskoncern lokaliserad i Bergslagen. De äger fyra sågverk varav tre är sverigebaserade. De levererar även GROT-flis till flertalet värmeverk och har ett behov av ett beslutsstöd som underlättar sortimentets flödesplanering och föreslår maskinsystem.
Projektets syfte var att skapa ett användarvänligt enperiodsbeslutsstöd med mål att maximera den totala vinsten och genom detta kvantifiera GROT-flisflödets förbättringspotential. Nio månaders historiska flödesdata kartlades och användes som jämförande testperiod.
Genom en fallstudie bestående av två scenarier analyserades optimeringar med månadsvisa, kvartalsvisa och säsongsvisa (9 mån) optimeringshorisonter:

Dialekter och röstigenkänning : Ett röstigenkännings-API:s förmåga att uppfatta svenska dialekters kännetecken och röstkombinationer
Allt eftersom utvecklingen går framåt inom applikationer och system så förändras också sättet på vilket vi interagerar med systemet på. Hittills har navigering och användning av applikationer och system mestadels skett med händerna och då genom mus och tangentbord. På senare tid så har navigering via touch-skärmar och rösten blivit allt mer vanligt. Då man ska styra en applikation med hjälp av rösten är det viktigt att vem som helst kan styra applikationen, oavsett vilken dialekt man har. För att kunna se hur korrekt ett röstigenkännings-API (Application Programming Interface) uppfattar svenska dialekter så initierades denna studie med dokumentstudier om dialekters kännetecken och ljudkombinationer.
Controlled traffic for grass silage production : an economic evaluation for dairy farmers
The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic
lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower
clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.
Uljabuouda vindkraftpark turbinmodellering och stabilitetsanalys
This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.
