Jämförelse av statistiska metoder för rangordning inom sjukvården

There has been an increasing interest for ranking of Swedish health care and a lot of emphasis has been placed on the creation of indicators in order to rank hospital units. However, essays on to what extent the choice of statistical method affects the final result of the ranking of health care units have not been given the same attention. For this particular reason, the main objective of this essay has been to investigate whether the choice of statistical model has a significant impact or not on the final result, by using five different, more or less common, statistical approaches: bar charts (with and without confidence intervals), control charts, logistic regression, multi-level analysis using shrunken residuals. The analyzed material in the essay comprises 24119 patients that all have been prescribed some form of the lipid-reducing medicine statin. According to directives given by Region Skåne, doctors are encouraged to prescribe a particular type of statin medicine, namely Simvastatin, which has been proved to be equally effective, but significantly cheaper than other statin medicines.

Påverkan av överprövningar vid offentlig upphandling : Belysa de konsekvenser som en överprövning frambringar ur ett samhälls- och projektperspektiv

I och med den nya globala ekonomin blir det allt mer vanligt med en ökad konkurrens. Inte enbart från den inhemska marknaden utan även via en global marknad som öppnats genom ett samarbete mellan nationer i Europa. Därmed finns en större tendens från företagen att dra en offentlig upphandling inför det svenska rättssystemet och bestrida beslutet som fattats av den upphandlande myndigheten då varje upphandling blir viktig att vinna. En tydlig orsak till det ökande antalet överprövningar är att i och med en regression i den globala ekonomin och med kollapser av nationella ekonomier runt om i världen så finns det en ökad vinning i att överpröva en förlorad upphandling då dessa är bristvara vid lågkonjunktur. Genom detta examensarbete kommer uppsatsförfattarna att belysa de problem och grunder som finns för att en överprövning skall uppstå som till exempel den allt för korta granskningstiden av tilldelningsbeslut, en saknad kompetens för en upphandling och möjligtvis ett allt för konservativt arbetssätt i det svenska rättsväsendet.

Motivera Mera! - En kvantitativ studie om samspelet emellan hedonisk shoppingmotivation och multikanalshopping

Multichannel-shopping has become a wide spread phenomenon in the retail industry due to a significant development of retail channels and formats. Consumers now shop for the same product category in many different retail settings and this trend is increasing. Therefore both the academic world and the retail industry are screaming for knowledge about the multichannel-shoppers. Several studies have focused on the characteristics of different channels and how multichannel strategies should be designed to minimize cannibalization. There is however a lack of research concerning what characterizes multichannel-shoppers and what drives them to shop in several channels.

Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :

Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.

Militant nationalism efter den 11/9 En fallstudie över den baskiska nationalistiska befrielserörelsen

In this thesis I discuss and analyse the use of violence of Basque radical nationalists after the 11th of September 2001 and the bombing of Madrid the 11th of March 2004. The field study is performed in the Basque country with interviews both on the French and Spanish side of the border with representatives from the Basque Nationalist Liberation Movement (BNLM).After the 11th of September the Spanish government continued its struggle against the countries own terror - ETA. But as the research will show the new political context after the 11/9 made it possible for the state to intensify the labelling of groups from the BNLM as terrorist organisations and thereby putting its members and leaders in prison for terrorism. My research shows that this social change may lead to a mobilisation of activists inside ETA, which in turn might create a continuity of the group's use of violence. The scenario is though challenged by an other setting in which the political situation after the 11/9 have made use of violence by militant groups like ETA illegitimate and irrational as a consequence of the mental trauma among the people of the western world.

Intranät - en kunskapskälla i arbetet?

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

Förstudie för implementering av affärssystemet Oracles tidrapporteringsmodul OTL (Oracle Time and Labor) : Kravhantering och GAP analys för tidrapporteringsprocess i Oracle EBS R12

This is a report for our thesis that was conducted as a conclusion of our bachelor degree in Business engineering at the Royal Institute of Technology (KTH). The work is done in cooperation with the firm Navigate Consulting Business Solutions AB.They have their leading expertise in Oracle E-Business Suite and has previously chosen to implement Oracle EBS R12. The modules that are planned to be implemented are general ledger (GL), accounts payable (AP), accounts receivable (AR), project module (PA), purchases, and CRM. For a consulting company like Navigate, it is particularly important to have a simple and effective time reporting process. We were therefore asked to provide new tabs with a decision-making process to determine if Oracle Time & Labor (OTL) is a useful time tracking system for their business.In order to achieve the company´s aim and objective we decided to follow a development method with five different phases.

LIDESK : En materialstudie för Edsbyverken

Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.

Läggning och resning hos ungtjurar i liggbås : inverkan av båsfrontsutförande

Cattle have a species specific movement pattern when lying down and getting up. They need sufficient space for their heads to perform these movements normally. The aim of this study was to investigate the lying down and getting up behaviour of beef bulls at a Swedish farm operation. The hypothesis was that bulls older than 10 months (over approximately 400 kg) were disturbed by a horizontal front rail and that the time to lie down and get up differed from what can be regarded as normal based on earlier scientific studies. The bulls were Swedish Red and White (SRB), Swedish Friesian (SLB) or crossbreeds of these two, and were kept in a cubicle system with a stall front design where there was a horizontal rail 40 cm above the stall floor.

ROLL UP! Produkten som förenklar hanteringenav en dragfjäder : Ett examensarbete som startade med en enkel idé och utvecklades till en prototyp

This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.

Säsongseffekter på den svenska valutamarknaden

Syftet med uppsatsen är att undersöka om de veckoeffekter och veckodagseffekter som observerats såväl internationellt som i Sverige även kan observeras på den svenska valutamarknaden för de tre valutorna; US-dollarn, euron och det brittiska pundet. Uppsatsen utgår ifrån den kvantitativa metoden med en deduktiv ansats. För att uppfylla uppsatsens syfte har den multipla regressionsmodellen med tillhörande dummyvariabler och hypotestester samt en variansanalys använts. Två undersökningar har genomförts, en med veckoindelning och en annan med veckodagsindelning. Uppsatsen utgår huvudsakligen från teorin om den effektiva marknadshypotesen (EMH).
