Problem: The question is if investors falls into psychological decision traps when they are about to make an investments decision. Research in other areas suggests that this may be case. The reason is that they are not aware of that psychological decision traps exist. If so, it can lead to pernicious consequences for the return on the portfolios they manage. Purpose: To investigate if investors fall into four different psychological decisions traps: anchoring, confirming evidence, overconfidence and regression towards mean, at investments in IPOs Method: We have collected data through a form of experiment.

AbstractArtikeln är en kvalitativ studie som syftar till att undersöka samverkan mellan organisationer sett ur socialsekreterares perspektiv. Den ämnar undersöka deras erfarenheter, åsikter samt attityder till samverkan för att kunna erhålla deras syn på arbetssättet. Samverkan som arbetssätt måste vara närvarande i människobehandlande organisationer för att säkerställa klientens bästa samt för att öka effektiviteten. Multipel problematik hos klienter gör det nödvändigt att organisationer samverkar. Socialsekreterarna i denna studie såg samverkan som nödvändig och de visar en positiv inställning till arbetssättet.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Tidigare forskning indikerar att deltidsarbeten har sämre arbetsegenskaper jämfört med heltidsarbeten både i Sverige och internationellt. Deltidsarbeten har i tidigare studier ofta klassificeras som ?dåliga? jobb. Med detta menas att arbetsegenskaperna skiljer sig ifrån den standard som gäller för heltidsanställda då deltidsjobben kännetecknas av låg kompensation, låg anställningstrygghet, få förmåner, att arbetet är låg kvalificerat och att det har låg status i jämförelse med heltidsanställningar. Kvinnor är överrepresenterade i deltidsanställning och eftersom relativt få män jobbar deltid kommer studien följaktligen att fokusera på kvinnor.

Sveriges ökade engagemang i internationella konflikter har förändrat under vilkaformer och i vilka miljöer som dagens militära operationer genomförs. Framföralltinnebär det att alla insatsförband inom Försvarsmakten ska kunna verka inom allakonfliktnivåer och i de flesta miljöer, även i urban terräng. Som en följd av dettauppkommer nya behov och krav på den indirekta bekämpningsförmågan i form avprecisionsbekämpning.Syftet med föreliggande arbete är att kartlägga om, och till vilken grad, ettkurskorrigerande tändrör bidrar till att öka den taktiska effektiviteten förstådd somverkanseffektivitet, kostnadseffektivitet, logistisk effektivitet samt minskad oönskadsidoverkan. Kartläggningen sker genom en komparativ litteraturstudie medkompletterande expertintervjuer.Med hjälp av kurskorrigerande tändrör som medger nära precisionsbekämpning kanen rad vinster erhållas. Exempel på sådana vinster är minskad spridning samt ökaddimensionering av verkan, minskad risk för oönskad sidoverkan, en lägre totalkostnad för ammunition samt minskat behov av transporter genom ökad effekt av detenskilda skottet..

Multiple sclerosis (MS) is one of our most common neurological diseases. The development of the disease often make the affected persons live with it for a long time. There are two types of the disease, the first is a progressive type and the other is relapsing remitting. Strengthening exercises isn?t commonly used as a treatment method although muscle weakness and fatigue are common symptoms.

In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..

Sarcoid is the most common tumor in horses all over the world. The sarcoid is a benign, locally invasive, usually fibroblastic proliferative skin neoplasm. Even if the etiology is not completley verified, the epidemiology and clinical behavior suggest a infectious intervention, probably BPV type 1 or type 2. However, it is known that the cause is multifactorial. A genetic prepdispositon has been identified associated to genes within the Major Histocompatibility Complex (MHC), but also to breed, age and perhaps gender.

Syftet med föreliggande studie är att få kunskap om hur medarbetarna uppfattar sina arbetsförhållanden, sitt välbefinnande i relation till arbetet och ledarskapet. Vidare syftar studien till att få kunskap om hur ledarskap påverkar medarbetarnas uppfattning om arbetsförhållanden och medarbetarnas välbefinnande. 85 deltagare (N=85) kompletterade ett webbaserad frågeformulär som bestod av 48 frågor med frågerubrikerna krav, kontroll, stöd, rättvisa, mobbing och trakasseri, hälsa och välbefinnande samt ledarskap. Resultatet visar att medarbetarna upplever sig ha delvis bra arbetsförhållanden och delvis bra välbefinnande. Vidare visar resultatet att arbetsförhållanden, välbefinnande och ledarskap korrelerar signifikant positivt med varandra där starkaste korrelationen finns mellan välbefinnande och ledarskap.

Syftet med denna studie var att beskriva hur personer med Multipel skleros (MS) upplever att sjukdomen påverkar deras dagliga liv. Metoden var en beskrivande litteraturstudie. Arton vetenskapliga artiklar av kvalitativ och kvantitativ karaktär analyserades. Databaserna Medline via PubMed och Cinahl användes vid sökningen av artiklar. Huvudresultatet i denna studie visade att personer med MS upplevde att deras sjukdom och dess symtom hade en stor påverkan på det dagliga livet.

The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.

ICA is the largest general dealer in the Swedish market as well as the largest supplier to the independent ICA-dealers. The principal and one of the biggest stakeholders of this thesis is the department Supply Chain Development who is responsible for the development of ICA?s Supply Chain.The purpose of this study is to examine how ICA?s sales are affected by weather and to make recommendations on how ICA should proceed with its work regarding this issue. By leveraging their forecasts by including weather, ICA hopes that their logistical metrics amount of spoilage, service levels and number of inventory days will improve. This thesis describes how ICA is working with weather currently, and furthermore it discusses the existing literature within this area.
