Förbrukningsreduktion : Ett alternativ till gasturbiner som snabb aktiv störningsreserv?
The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.
Arbetsmotivation trots osäkra arbetsvillkor? : En kvalitativ studie om arbetsmotivation hos anställda med osäkra arbetsvillkor
Studiens syfte är att undersöka arbetsmotivation och motivationsfaktorer hos anställda med korttidskontrakt på ett företag som arbetar med sådana praktiker. De formulerade frågeställningarna är: Hur anser anställda med korttidskontrakt att deras arbetsmotivation påverkas av de osäkra arbetsförhållandena? Vilka motivationsfaktorer är viktiga för dem? Vilka strategier har de för att motivera sig? Empirin bygger på intervjuer genomförda med 6 respondenter på ett företag som utgör typfallet för studien. Den teoretiska referensramen består av Deci och Ryans definition av inre och yttre motivation och Herzbergs tvåfaktorsteori. Tidigare framforskade resultat med koppling till nämnda teorier har legat till grund för databearbetningen.Ur resultatet kan utläsas att anställda med osäkra arbetsvillkor motiveras av givande arbetsuppgifter, att genom sitt jobb ha möjlighet att hjälpa andra människor.
Med tanke på vintern : ett gestaltningsförslag för Broparken i Umeå
It may seem obvious that the urban space in our northern
cities should be design to function and inspire throughout
the whole year. This is not always the case. The urban
space is often designed on a summer basis and the winter
is regarded more as a problem then a resource and its
potential remain unused.
I have in this master thesis studied the impact of the
winter on people and spaces and ponder on how to design
functional and attractive places for winter. The project
ends in a design concept for Broparken in Umeå on the
theme "everyday winter day".
The work with this thesis has given me, as a landscape
architect, valuable experiences and filled a gap of
knowledge that I had in this subject. I hope that this thesis
can inspire Umeå kommun and others who are interested
in how northern cities can benefit by its climate and
develop towards a more complete city.
The thesis begins with a chapter that present the subject
from four different perspectives.
Kuratorers arbete med gymnasieungdormars psykiska ohälsa: en kvalitativ studie
The overall aim with this essay was to study how counsellors at upper secondary school work with mental illness among youths and compare this with what research and theories advocate. This because there has been a rise in the number of people, especially in the age-group 16-24 years, suffering from different degrees of mental illnesses. The school can in some aspect contribute to cause mental illness but it also consists of good opportunities to offer counselling and work to prevent mental illness among the students. This study consists of five qualitative interviews and two short telephone interviews with school counsellors. During the interviews they expressed their thoughts concerning factors that causes mental illness among youths and gave an account of how they work with prevention, counselling and collaboration.
Vem vinner: fackboken eller den skönlitterära boken? : en studie över lånevanor i en 3:e klass i en mindre by i norra Sverige
The purpose of this thesis is to investigate the habits of borrowing books among third-grade pupils. My aim is also to study what significance their teacher and the librarian have on the pupils? borrowing habits. Based on the results from an experiment, two observations, interviews and by compiling a list of short summaries of literature relevant to my thesis. I wanted to compare earlier research with my own results and also reflect on remarks made by librarians and teachers concerning the children?s reading and use of the library.
Industriforskning och informationssökning: en användarstudie av en grupp forskare vid ABB Corporate Research

Utbyggnad Av Eriksberg
During the years of development in the 60s and 70s the need for new housing in Sweden arose. Sweden was going to be the most modern country in the world. This period has later been called ?the time of the big programmes?. One of the parts in this building of a welfare society was a large policy of building politics with few counterparts in history.
Arbetstrygghet i Bemanningsföretag
Syftet med studien var att studera arbetstryggheten av de anställda via bemanningsföretag, vilket utfördes utifrån tre trygghetsaspekter; psykologiska, sociala och ekonomiska. Studiens forskningsdesign är en fallstudie, även kallad för representative fallstudie, i vilket man studera en vardaglig situation eller en form av organisation. Denna fallstudie omfattade en specifik faktor och en specifik bransch, vilka är arbetstrygghet och bemanningsföretag. Det empiriska materialet samlades in genom semi-strukturerade intervjuer med sex personer varav tio uppdrag sammanlagt, som arbetar eller har arbetat via bemanningsföretag. Tolkning av det empiriska materialet genomfördes i form av en analysmodell som skapades utifrån tidigare forskning kring studieämnena.
Kommunikation och samarbete. En studie av bibliotekariers och lärares förhållningssätt gentemot varandra gällande samarbete
The purpose of this paper has been to study the relationships and attitudes of a few teachers and librarians as to their co-operation in a combined public and upper secondary school library and to find out what circumstances there may be to exert an influence on their work. The paper has been based upon qualitative interviews with upper secondary school teachers and librarians as well as on studies of literature relating to our issue. We believe there may be different approaches to the learning process, as these are the relations and attitudes of two professions from different trades. That is why our point of departure has been Roger Säljö's theory about learning and, in our analysis, a few of Jean Donham van Deusen's ideas of joint planning and flexible timetabling. All respondents agreed that co-operation could be better, but the teachers were of the opinion that it must not interfere with their time.
Är valutamarknader effektiva? : En kointegrationsanalys av spot- och forwardkurser
Enligt den effektiva marknadshypotesen (EMH), utvecklad av Fama på 1960-talet, skall priset på en finansiell tillgång reflektera all tillgänglig information på marknaden. Effektiviteten kan delas in i svag, mellansvag och stark form. Syftet med vår uppsats är att analysera huruvida ett antal växelkurser är effektiva i svag form, det vill säga att priset på en växelkurs reflekterar all historisk prisinformation. Vår studie omfattar tio länder, samtliga med rörliga växelkursregimer. Vi använder oss av kointegrationstest samt test för förväntningsriktighet för att kunna verifiera EMH.
Vad kostar korttidssjukfrånvaron?
Bakgrund och problem: Långtidssjukfrånvaron har länge varit ett uppmärksammat problem och flertalet åtgärder har satts in för att minska denna. På senare tid har korttidssjukfrånvaron dock lyfts fram som ett ytterligare problem och erhållit en större uppmärksamhet i takt med dess ökning. Korttidssjukfrånvaro syns inte i offentlig statistik förrän efter den åttonde dagen och är därmed svår att studera. Likaså kan kostnaden för korttidssjukfrånvaron vara svår att fastställa eftersom korttidssjukfrånvaro består av både direkta- och indirekta kostnader.Syfte: Syftet med denna studie är att beskriva och förklara hur stora kostnaderna är för den korttidssjukfrånvarande socialsekreteraren på en enhet i Växjö kommun. Utifrån dessa kostnader ska sedan en metodik utformas för att kunna fastställa en standardkostnad för vad korttidssjukfrånvaro per timme kostar.Metod: Under studiens gång har en abduktiv forskningsansats, en kvalitativ forskningsstrategi och en fallstudie som undersökningsdesign nyttjats.
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.
Folkbibliotekarien och det livslånga lärandet En undersökning av ett projekt till stöd för vuxenstuderandes livslånga lärande
The purpose of this master thesis is to investigate issues concerning lifelong learning and the role of the public librarian. This is done by examining LärForum Forum for Learning, a project initiated at a public library located outside of Stockholm, with the aim of supporting adults lifelong learning. The major questions raised in this study are: How do the seven librarians interviewed define lifelong learning and how do they perceive their own role in relation to lifelong learning in the public library? Do they work with adult learners in a different way than they do with "ordinary" users of the library? Has their conception of their own role as a public librarian changed as a result of LärForum, and do they find it necessary to acquire new skills because of the project? Data was collected through interviews and observation, and the study is a qualitative case study. The main results are that the librarians see their role in lifelong learning in the public library as self-evident, and they see lifelong learning mostly as learning for an individuals personal development.
Mäns kroppsuppfattning
Ända sedan antiken har en atletisk och stark kropp varit idealet för män och idealet lever kvar än i våra dagar. Kroppens utseende och form verkar bli allt viktigare för människor, många olika åtgärder vidtas för att få en ?fulländad? kropp. Forskning kring kroppsuppfattning har mest riktat sig mot kvinnor och framhävt kvinnors missnöje med sina kroppar. Relativt få studier finns att tillgå som behandlar mäns kroppsuppfattning.

In order for companies to be successful with their marketing, they ought to build a strong, personal and enduring relationship with their customers by being attentive of their target group. The main purpose of the social media is to encourage individuals to interact and conduct dialogue with the participants rather than focusing entirely on one way communication. Furthermore, in order for a company, regardless of size, to be successful in building a healthy relationship with their costumers, they ought to showcompassion for their feelings and needs, as well as providing them with as much information as possible, via all of the selected social media tools to work with.
