Numerical simulations of fluid-structure interaction of a water-filled tube with a free surface are conducted using an implicit partitioned coupling scheme. Abaqus and STAR-CCM+ are used for the solid- and fluid domains respectively. This application has stability issues, with the most severe turning out to be the added mass effect. Rayleigh β damping and grid flux under-relaxation has been used t
This study aimed at generating psychological knowledge regarding how the middle manager experiences his/her communicative role during an organizational change. For this purpose, qualitative interviews with several middle managers were conducted at a company located in the south of Sweden. This company had recently gone through an organizational change in which they had merged two different busines

Metoden var en litteraturstudie med elva vetenskapliga artiklar från databaserna CINAHL och PubMed med både kvalitativa och kvantitativa ansatser. Resultat
I present a theoretical model for competitive interaction between schools and grade inflation. To test the model, I estimate the effect of competition on grade inflation in Swedish upper secondary schools using data from all schools in the years 2012-2015. To solve the endogeneity problem of competition, I use Instrumental Variable estimation with Fixed Effects. I use the sudden shutdown of 17 sch
The primary purpose of this Master’s thesis was to understand the consumer behaviour of elderly people, more specifically the silent generation in regards to adopting household robotics. The objective was to gain a deeper understanding on the attitudes, beliefs and intentions, as well as values and attributes that are affecting the consumer behaviour of elderly people to determine whether elderly
This thesis considers a hypothetical Pigouvian tax on meat in Sweden. The theoretical framework regards controlling for externalities and previous empirical research of excise duties on food, which end up in a Cost-Benefit Analysis (CBA) with a policy recommendation. Food production contributes up to as much as 26% of all GHG emissions and increasing meat consumption are positively correlated with
Bakgrund: I samband med ett operativt ingrepp kan ett personcentrerat vårdande underlätta kommunikation och samarbete mellan patienten och operationssjuksköterskan. Syfte: Syftet med studien var att synliggöra operationssjuksköterskans erfarenhet av personcentrerad vård i den perioperativa kontexten. Metod: En kvalitativ intervjustudie genomfördes med tio operationssjuksköterskor på två sjukhus i
Användningen av Business Intelligence på mobila enheter har ökat då det leder till förbättrat beslutstagande eftersom användarna kan få tillgång till information var de än befinner sig. Kraven på BI-systemen förändras då mobila enheter har andra förutsättningar som till exempel mindre skärmstorlek. Det finns existerande forskning kring vilka kritiska framgångsfaktorer användare av Mobile BI-system
Business cycles and changes in macroeconomic variables can have a huge influence on the profitability and credit exposure of an individual bank. Consequently, they affect the risk profile of a given bank. This study uses multifactor time series regressions to examine the influence of global macroeconomic variables on the probability of default for Nordic banks, both on industry level and on indivi
The aim of this study was to examine how professionals working in residential care units for unaccompanied children, construct and understand integration and culture. The study was built on empirics which was the result of five semi-structured interviews held with professionals working in this field. The interviews included both professionals working in the public sector and professionals working
Today densification of existing urban fabric is the main strategy for how to sustainably meet the needs of a growing population. But what does this development mean for ecological values inside of the city? Historically, we have thought of cities and the human kind as apart from nature, as a defense from wilderness and natural forces. Today we can no longer think only of ourselves as vulnerable to
Information and Communication Technologies (ICTs) are becoming increasingly influential in social, economic and political spheres and have also been recognised for their potential within health promotion, especially when targeting youth and adolescents. Despite the potential of these new technologies, there is a growing understanding of how prevailing inequalities between men and women and socio-c
The problem with adolescents who do not want to participate in investigation processes as witnesses, is a recurring problem for investigators with the police in Örebro. A problem that contributes to many disused investigations, despite the known existence of potential witnesses to the different crime events that involve youths. The purpose of this study is to analyze the causes that contribute to
Collaborative filtering is a method for making predictions about consumer interests by collecting preferences or information about opinions from other consumers. For this purpose statistical modeling techniques are applied to learn personalized models for each consumer based on every purchase or provided rating to the available items. Such a technique is probabilistic Latent Semantic Analysis (pLS
Textilindustrin – en vattenintensiv verksamhet Slutnotan för mängden vatten för att producera ett klädesplagg – från odling av råmaterial till tvättning samt färgning av plagget – landar idag på flera tusen liter. Den vattenintensiva produktionen sker i en stor utsträckning i utvecklingsländer, där uttaget av vatten i kombination med undermålig infrastruktur, otydliga regler och ökade klimatföränIn this study I intend to examine how textile companies address water in its operations. This is of particular interest due to the fact that water is used in huge amounts in the manufacturing process, when growing fibres for the cloth, when dyeing and washing it and in other related processes, and therefore especially important to address because of the increasing water crises all over the world –

The aim of this thesis is to map the Storytel users: who they are, what they listen to, and how they use the service. The thesis also aims to analyse how the audiobook medium affects the reading experience. In order
Pälsdjursuppfödning är en kontroversiell näring som helt eller delvis förbjudits i flera europeiska länder. Finland är en världsledande pälsproducent, men även dess legala status utmanades då medborgarinitiativet Turkistarhaton Suomi (≈ Finland utan pälsfarmer) syftade till att kriminalisera all pälsdjursuppfödning i Finland p.g.a. välfärdsproblem hos involverade pälsdjur.

This research explored how entrepreneurs differ from non-entrepreneurs regarding creative,rational, and intuitive thinking. Individuals’ creativity was tested through the Kaufman Domain of Creativity Scale (K-DOCS). Individuals’ rationality and intuition was tested by the Revised Rational Experiential Inventory (REI). Analyzing from 68 entrepreneurs and 106 non-entrepreneurs from all over the worl
The Swedish restricted categories in terms of ethnicity and race which where once settled as a way of creating tolerance has shown to be problematic causing even more racism. Borders or categories are built to create structure and order but instead they are causing ambivalence for the growing group of people that fall in between. The aim of this study has thereby been to investigate the experience
The current refugee crisis can be said to have affected not only actual borders, but also borders within subjectivities. With a poststructuralist and deconstructive approach, subjectivities are recognized as constructed through language and within discourse, and in turn, induced through policy. Thus, in order to examine the discursive construction of subjectivities, this thesis critically engage w
