Does the country people live in affect the probability of them experiencing happiness? Can a country variable in an ordinal regression model be affected when microeconomic and macroeconomic factors are added to the model? The possible outcomes are either that the country variable affects less when the additional predictors are added to the model, or that they stay the same. The micro data is collected from the European Social Survey database, the macro data is collected from the World Bank. The country variable becomes less substantial when additional variables are added to the model. The variable with the most influence over expected happiness apart from the country variable is whether the individual often socializes with friends or not.

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

The problem of finding targeted medicine is a central problem in chemotherapy. From this point of view the ubiquitin-proteasome system is a highly promising object in the pharmaceutical approach. Proteasome plays a critical role in cellular protein degradation, cell cycle and apoptosis regulation.Proteasome inhibitors are substances blocking the actions of proteasome. Cancer cells are more sensitive to inhibition of the ubiquitin-proteasome system than normal cells. Therefore proteasome inhibitors have the potential to be successfully used in the cancer treatment.The study aimed to test various substances to identify possible proteasome inhibitors with the IncuCyteTM FLR image system and fluorometric microculture cytotoxicity assay.

The main purpose of this thesis is to investigate how books are weeded in some Swedish public libraries today. It tries to shed light on some of the problems and obstacles that may arise, and on the criteria used by staff for weeding. I also hope to build a model for weeding, based on the results of my investigation. The method I have chosen for my work is qualitative interviews. The results of my thesis indicate that weeding is not the top priority of the staff at the investigated libraries.

The purpose of this essay is to present, from a theoretical framwork about regional democracy, possible methods to handle the regional democratic problems in Östergötland in Sweden and to investigate the opinion of the political parties regarding this issue. Both the national and the local/regional level are investigated. The contents of the essay is based on literature studies and interviews of politicians in Östergötland. Regional democratic problems that is discussed are the political responsibility and the power distribution between the political actors on the regional level. A solution of the problem could be to organize the regional society structure in accordance with one of the following organization models"Statligt regionalt ansvar","Kommuner i samverkan"or"Regionalt folkstyre".

Background: Every patient and each situation is unique. Therefore the nurse has to act in a flexible intervention and still keep an ethical perspective. Aim: The aim of this studie was to illuminate nurses? different aspects of decision making in emergency situations. Method: The result is based on nine scientific articles.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

The aim of this paper is to study and outline the factors governing political leadership at the party leader level, and to conclude to what extent a party leader rules and to what extent the party leadership is contextually determined. The theories used are based on Elgie's interactionistic study of political leadership and Stewart's organisational model of leadership as well as political culture.Thus, the questions raised are if the leader leads or if the leader follows; if the leadership environment is formed by the leader or if it is, merely, implemented on the leader; and what a model of the political leadership consist of? To answer these questions a text analysis comparing Sahlin?s speeches to the party?s political programme is used as well as in-depth interviews with members of the Board of Party.The conclusion shows that the leadership is contextually framed, but the leader is free to implement his or her ambitions within that frame as long as it is coherent to the party line..

The purpose of this essay is to examine whether the descriptions of Stalin's terror in history textbooks for high school changed from the 1950s until the 2010s. Since previous research shows that textbook content is influenced from different directions and that it dominates in teaching, therefore I want to find out what similarities and differences that exist in the textbooks. The survey is based on a qualitative approach because I want to have a profound picture of the descriptions of Stalin's terror. The results of the survey show that the number of casualties and the descriptions on the famine has changed over time. Furthermore, textbooks also found it difficult to distinguish between terror, politics and ideology.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Service delivery acts like a process. This can enable the possibility of attracting attention towards the company who?s making use of this, furthermore generate several opportunities. However, it?s far from easy to deliver new services.

Today, the TV vignette is considered an embellishment to a TV program, despite its broad audiences and unique appearance. We wanted to find out if the television vignette has some common features and conventions but also find out how it relates to genre.We used a case study where we analyzed ten vignettes that we chose from certain criteria. We used a model based on image analysis that we modified to fit our needs. The main parts of each model consisted semiotics, imagery, dramaturgy and sound.We also made a couple of interviews with people who are active or used to work with vignettes. As a result we discovered that the television vignettes consist of certain conventions and that the vignette will not be considered as an independent genre, until the public has accepted it.

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.
