This study is intended to identify which factors that influence the success of initiatives in Customer Relationship Management, usually abbreviated as CRM. In the course of this study we have been in contact with forty-two companies operating in Sweden within eleven different sectors in order to find out how they operate regarding CRM initiatives, particularly initiatives within marketing and promotions. Against the data collected during the study it was concluded that the companies working with CRM believed that the CRM initiatives resulted in higher profitability and created more loyal customers. At the same time it was evident that the companies had different views on CRM as a method and its benefits. The majority of the companies could not present any tangible results from CRM-initiatives. It was also revealed that decisions regarding CRM initiatives were based on subjective assessments and without theoretical foundation.

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.

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 main question of this study is about how reorganizations influence on the mental social working environment for chiefs in municipal care. We want to find out how chiefs experience their mental social working environment in a reorganization. The method we used was a qualitative method. We interviewed eight chiefs in municipal care. The interview was done in two different municipalities, where we interviewed four in each municipality.

In the 1960?s, Paul Hersey and Ken Blanchard developed a theory called Situational Leadership. Situational Leadership is a model where the leader analyses the needs of the situation and the needs of the people to be led. After analysing the situation, decision is made on what leadership style to adopt. The Situational Leadership model was developed in a company environment.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.

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 Master?s thesis is to investigate if the library can be a real partner for researchers in managing and dealing with their research information. In this study, six researchers have been interviewed about their problems with information management. This study uses the method Critical Incident Technique for the interviews with the researchers. This method focuses mainly on problems and what happens around those problems.

Creativity and innovation have become two very important concepts in today?s society where the demand for these abilities are sought after. At the same time, the school system of today follows a more traditional outlook on what learning and knowledge means.The extend students ability to understand and elevate their motivation is possible through creative methods of working. In order to create a school system which can withstand the demands of the future by including creative methods in its model, a study was carried out to examine how teachers? thoughts on creativity could mean for its development.This study took place in an elementary school in Sweden where Entreprenöriellt Lärande (EL) has been in use for the last two years.

Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.

Titel: Innovate or Stagnate! ? Open innovation in manufacturing small and medium-sized businesses in Småland.The purpose of the study is that, from a leadership perspective (innovationmanagement), create a better understanding of open innovation in manufacturing small and medium-sized enterprises. The study therefore intends to contribute to the understanding of how open innovation processes leads to greater innovation in manufacturing small and medium sized businesses.We have used a qualitative research method and adopted an abductiveapproach. We made interpretations and created meaning based on our research results.Our theoretical framework is based primarily on Chesbroughs (2003) research on open innovation. Based on this model, we have selected a number of other theories, which we perceived as prerequisites for small andmedium sized companies in open innovation processes.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Sweden is a member of the European Union since 1995. The European Union issues directives that cover different areas. Member states must implement these directives into their national legislation. The European council issued in 1993 a directive that took action on the organization of working time, also known as the working time directive. The full name is: Council directive 93/104/EC of 23 November 1993 concerning certain aspects of the organization of working time.
