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.

The aim of this Master?s thesis is to investigate the library habits of young people, age 15 to 24. Our empirical data are gathered in a survey distributed to 104 young men and women at three different public libraries. The questions are about how young people use the public library, what media and services they use and whether or not they are content with what the public library can offer them. In our analysis we have compared our results to previous research and used a model by Marianne Andersson and Dorte Skot-Hansen to determine how they use the library.

The purpose of this bachelor?s thesis is to examine video games, gamers and gaming from an information science perspective. The purpose of the study is partly to study video games as a type of information system and partly to study gamers information use, information seeking and also the experience of gaming. A selection of five games have been analysed using a topology for video game analysis created by Espen Aarseth. A quantitative investigation has also been made, in the form of a web survey distributed through four Swedish online forums, the result of which was analysed using Carol Collier Kuhlthaus model of the information seeking process.

The aim of this Master?s thesis is to investigate international students? views regarding information seeking and use of information sources. A further aim is also to investigate the possible factors influencing information seeking in relation to everyday life for international students. Interviews were carried out with eight international students, 20-35 years old from three continents. They were to stay in Sweden for at least five months for the purpose of studying.

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.

Ett problem för dagens organisationer är hur information sprids och vem som tar del av denna information. Detta informationsöverflöd innebär att den information som sprids inom en organisation måste ha mening, syfte och vara av relevans för personalen och för att kunna begränsa informationsmängden måste personalens upplevelse av informationen tas i beaktande. Studien har genomförts med teorier om informationsspridning och kunskapsutbyte. Inriktningen på arbetet har varit mellan ansvarig chef och anställda inom en organisation. Den informationsspridning som sker inom den undersökta organisationen är i grupp, individuella träffar samt virtuella forum.

Background: For an individual a surgery may involve strains and risks. Many patients experience a loss of its own identity and often an inability to control the situation while going through a surgical operation. Fear of pain or to not wake up from the anesthetic or that the surgery will fail are worrying factors that some people experiences. Purpose: The purpose was to describe patients? perceptions of preoperative information in connection to elective surgeries.

This thesis studies the relationship between risk and the first day returns of Initial Public Offerings (IPO) by assessing the risk of each issuing company with a risk model that combine financial key ratios of importance. The study is based on 92 IPO?s that were made on the Stockholm OMX stock exchange during the period of 1997-2009. The point of departure was to investigate if the uncertainty created by the asymmetric information between investors and the issuing firm could be captured by predicting the possibility of failure in the future. This has been studied by applying Skogsvik?s probability of failure model on the 92 issuing firms.

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

The purpose of this thesis is to gain a better understanding of how elderly people seek and use information in everyday situations. A further aim is to suggest ways for the library to offer more services specifically tailored for pensioners. This is an important topic as pensioners are a rapidly growing group of library users. We conducted qualitative interviews with four elderly people concerning their information needs in everyday life, and discovered that they rarely use the library, preferring instead to get their information from various internet sites and their pensioners? organisation.

This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.

This thesis investigates clinical nurses? information seekingand information use through semi-structured interviews withsix nurse practitioners, nurses with further education.Previous research shows that nurses have problemsimplementing evidence-searching at the clinic because oforganization, stress and heritage of an old practice that doesnot incorporate the academic education.The theoretical framework consists of T.D. Wilson?sinformation seeking behavior model and R.H. Orr?s model ofinformation needs.
