Förslag på riktlinjer för datainsamlingen vid kommunala olycksundersökningar
Bakgrund: Enligt lagen om skydd mot olyckor (SFS 2003:778) skall en olycksundersökning genomföras vid alla olyckor i skälig omfattning i syfte att finna orsak, händelseförlopp och utvärdering av räddningsinsatsen (SFS 2003:778, kap3, 10§). Bland genomförda olycksundersökningar i Sveriges kommuner har Statens Räddningsverk identifierat en stor inbördes variation gällande innehållet i utredningarna och brister vid vidarebefordring till myndigheten för statistisk analys. Uppsatsen är därför ett led i myndighetens utveckling av stödet för datainsamlingen vid kommunala olycksundersökningar i syfte att förbättra förutsättningarna för goda lärdomar vid olyckor.Syfte: Syftet med uppsatsen är tvådelat. Att först analysera vilka erfarenheter som samlas in av de kommunala olycksutredarna och därefter verifiera resultaten utifrån tidigare forskningsresultat.Metod och material: Med metoden kvalitativ innehållsanalys har ett urval av kommunala olycksundersökningar analyserats (n=21), där insamlade erfarenheter har kategoriserats i ett antal gemensamma teman. Underlaget (n=68) är hämtat från Statens Räddningsverk och bestod av alla vidarebefordrade kommunala olycksundersökningar mellan 2005 till och med april 2007 fördelade över 8 klassifikationer.Resultatdiskussion: Utifrån tidigare forskningsresultat har sedermera resultaten verifierats.
Möte i månsken : ett belysningsförslag för Fyristorg
The object of the thesis is to propose a new lighting plan
for the square Fyristorg in Uppsala, and to describe the
process which have led to it.
It all started when I choosed the place together with the
municipality of Uppsala.
I have been doing research and analyzed how the place
and it´s existing lighting works both during different times
of the day and also in the evening.
After researching the place and it´s existing lighting I´ve
decided to put up the following goals fot the new lighting
design.
1. The general light level of the place shall be experienced
as higher than today.
2. The light level of the place shall be adapted to the light
levels of surrounding places.
3. The lighting shall be free from glare.
4. The lighting shall be adapted to people passing by.
5.The lighting shall be adapted to the surrounding
architecture.

Wilhelm Reichs mottagande i Sverige psykoanalys, marxism, biologi och kosmologi
In this essay I have been writing about the psychoanalyst Wilhelm Reich. It was written at the Library School in Borås as a contribution to the struggle of the maintenance of the free word. In the essay I have been concentrating on how Reich was received in Sweden from the publication of his first book 1927 to the year of 2000. The work started with a biographical chapter and a chapter about Reich's scientific development, which was divided into three phases: one psychoanalytical and Marxist, one physiological and biological and a third phase that makes a synthesis of these in a cosmological form. The analytic material has been books and articles from periodicals and papers.
Könsselektering av spermier från lantbrukets husdjur
Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.
Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori
The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.
Dietrich Bonhoeffer och den religionslösa kristendomen ? eller att vara kristen är att vara människa
The overall purpose of the essay is to analyse what Dietrich Bonhoeffer meant by Religionless Christianity. For this I have chosen to use the substantial idea analysis.I first came across the concept of freedom of religion to Christianity and Religionless Christians, in the book Dietrich Bonhoeffer: Tankar om en 1900-talsmartyr by Martin Lind in which he discusses what Bonhoeffer might discuss with Religionless Christians. This book is therefore the origin of the selection of literature I have chosen to use in the essay. Bonhoeffer writes several letters from prison about the movement he sees towards a new phase in human history, in which man can no longer be religious. However, Bonhoeffer uses the word religion in such a way that its content cannot be clearly determined.
Genomarbetade förfrågningsunderlag medför tids- och kostnadsbesparingar : En studie över handlingars påverkan i byggskedet
In order for construction projects to be completed within the specified time limit while at the same time be financially sustainable it requires thorough preparation and an extensive planning. Most essential is the groundwork and the design that determines the project's progress. There are many aspects to consider in order to avoid inconveniences such as delay, litigation, unexpected cost etcetera. If mistakes are made in an early stage it is very likely that the error will follow the process and become an expensive correction cost towards the later part of the project. In other words, it is expensive to rectify defects later on.
Förändring av varumärken
This thesis aims to study brand change, which can be of interest since a brand during its lifetime can be expected to meet a lifecycle consisting of five phases; innovation, introduction, growth, maturity and recession. In order to avoid the recession phase and the sales decline that follows there is a need for a change of the brand.In order to study brand change, theoretical framework is compared to two real world cases that have gone through an active change.The conceptions of positioning, repositioning and revitalization are clarified. Positioning deals with how brands are located in customer?s minds as well as on the real market. Repositioning implies a change of the current position and is also often a move towards a new market segment.
Nyhetens behag: En textanalytisk studie av litteratur som bygger på nyhetshändelser
The purpose of this Masters thesis is to examine literature on current media events. We see a close relationship between this literature and the media society where we relate Manuel Castells theory of the network society. In this thesis we have chosen books which give different views on three major media events in Sweden: 1 the assassination of Anna Lindh, the former Swedish Minister for foreign Affairs; 2 the Knutby murder and; 3 the Tsunami disaster in Southeast Asia. These books combine fact and fiction in their writing which in media science is called faction. This form of writing has similarities to genres like new journalism and documentarism and can be problematic for the reader in terms of genre expectations because of the mix of fact and fiction.
Logistiska lösningar för en lönsam byggprocess
This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.
Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
De svenska fastighetsbolagens redovisningsval för förvaltningsfastigheter och dess effekter på redovisningens kvalitativa egenskaper : En studie av noterade respektive onoterade svenska fastighetsbolag efter implementeringen av internationellt regelverk
AbstractTitle: The Swedish real estate companies choices of valuation within investment properties and its further effects on the qualitative characteristics of accounting.-A study of the Swedish real estate companies listed and non - listed on the stock market, after the application of the international rule board.Background and Problem: From January 2005, all companies, listed on a stock market within the European Union, are required to prepare their consolidated accounts using common set of International Accounting Standards, IAS/IFRS. In Sweden, this opportunity has also been given to non-listed companies, to voluntary implement these rules in their consolidated accounts. One difference between Swedish accounting rules and contemporary International rules, deals with the accounting treatment of investment properties, which foremost affects the real estate market?s accounts. In contrast to the Swedish Financial Accounting Standards Council?s recommendation RR 24, the new standard, IAS 40, permits a choice between different accounting alternatives.
Att leta bänkbok: bänkbokspraktiker i skolbiblioteket.
The purpose of this Master's thesis is to contribute to a betterunderstanding of children's free time reading book practices by studyingpupils in the school library and their processes of finding and borrowingbooks for themselves to read silently in the classroom, so called free timereading books. The study also includes observations of the staff's role,particularly the school librarian's in supporting pupil's book selection.The empirical material consists of field notes from an etnographic studywhere pupils in 4th grade (aged 10-11) and staff were observed duringthree school library visits. The theoretical framework is inspired byLennart Björneborn's concepts of information practices in libraries:serendipity, integrative library interface, mediation flow and affordancespaces.The study shows that pupils' search for free time reading books in theschool library is relatively routine-based at the same time as it isspontaneous. The process is an interplay with factors such as time,display and interaction in the integrative library interface. In the presenceof adults, finding books becomes an imposed task for the pupils.
Jeanne d'Arcs kanonisation : en kyrkopolitisk strategi eller skapandet av en nationell symbol
The following essay is named The canonization of Joan of Arc, a Church political strategy or the creation of a national symbol? Joan of Arc, the French heroine of the Hundred Years War, was canonized as late as 1920, in a process that began already in 1869. In the following essay I am trying to work out if this canonization is a work of the Vatican in order to gain popularity in France after the breakup with the state in 1905. The Catholic Church had, since the French Revolution, faced difficulties withstanding its position of power in the presence of the upcoming Secularism and Liberalism and their growing public support. The Catholic Church had been fighting for its members and at the same time fighting the new ideas of Socialism, Communism and Liberalism.
En studie om lärares arbete vid övergångar : Hur arbetet som bedrivs i arbetslaget återspeglas på individ, grupp och organisation
This thesis is based upon the assumption that in Swedish school today it is a wide gap regarding the information flow when pupils are switching school. This was one of the reasons Skolverket published a report clearly stating that this is the case. The purpose of this thesis is to examine and describe how teachers are working in a teacher team at transitions to see and understand what their work may mean individually, in a group and to the school as an organisation. The questions at issue is to see how the teachers cooperate during transitions and how they notice students in need of extra support and students level of knowledge during transitions. The two last questions at issue is first to see how teachers approach parent?s expectations on the school and the teachers, secondly it is to examine what implications their work will have on the school.
