During the past year it has been made possible to buy back a company?s outstanding stock. This is done in order to change the capital structure towards a situation with less equity. A change in capital structure means a change in the cost of capital for a company and by that a change in the value for the stockholder. This Master Thesis studies the relation between capital structure and business risk.

Syftet med undersökningen är att ta reda på om begreppet ?Tekniska system? tas upp i förskolan. Dessutom undersöks hur förskolorna arbetar med teknik enligt den reviderade läroplanen, Lpfö 98.Som metod användes enkäter där pedagoger satt i arbetslagsgrupper och besvarade frågor. Enkäten används för att få en bättre bild av hur ålder, kön, tidigare utbildningar och yrkeserfarenhet förhåller sig till kunskapen av teknikämnet.Undersökningen visar att alla förskolor använde sig av begreppet tekniska system på ett eller annat sätt i samtal med barnen, till exempel vid toalettbesök, samt frågor ?vart tar rören vägen vidare till reningsverket??Vidare framkommer det att fler fortbildningsdagar och studiebesök är önskvärt för att pedagogerna ska få en större vetskap om begreppet tekniska system.

Our study aimed at gaining insight of co-workers experiences of different factors that affects the verbal communication and leads to dialogue and misunderstanding between co-workers and their managers. The empirical material was gained from semi-structured interviews with co-workers at various departments within the same organization. We used a hermeneutic interpretive approach and our data was analyzed concerning different factors affecting communication. The result has been interpreted using the theories of deliberative conversations and dialogue competence. We have also used Illeris theory of learning.

Given that the end-customer has become more demanding, the retailer has to deliver products according to the market demands, which have forced manufacturing companies to constantly search for new opportunities to reduce costs and improve efficiency. It is, therefore important to choose suppliers that are able to compete with the market demands.The market demands in the textile industry have lead to shorter product life cycles, which have caused manufacturers to deliver flexibility with high technology to compete successfully on the global market. To achieve the market requirements the underlying factor is to be aware and optimally use and control time. New technology can have a major influence in the production development, if the company choose to take benefit of the advantages, by optimal allocation of the internal resources the productivity and efficiency will increase, to accomplish a competitive advantage. One way to achieve this is by investing in a Unit Production System.In our thesis we have questioned what the main driving forces for an apparel manufacturing company is when it chooses to invest in new technology.

The results show that many of these factors influence the choice of dish, especially those related to gender.

Background: In our case study we have been studying a company that during the last seven years have tried to implement the control system Balanced Scorecard. They have during this period made three attempts. According to Kaplan and Norton, the creators of Balanced Scorecard, it should take about 16 weeks to implement a Balanced Scorecard. Purpose: Our purpose is to investigate which factors that influence the possibility to implement Balanced Scorecard. Method: We have conducted a case study where we have studied implementation at three levels in a company.

SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.

The purpose of this Master thesis is to examine how college library managers perceive shelves of book reservation system in an integrity perspective. Privacy is an important part of everyday life in the society of today and according to some people, for example a former library lawyer in the Swedish Royal Library, these shelves conflicts with the Swedish law of Secrecy (Sekretesslagen 9 kap. 22 §). I am therefore interested in how they perceive this system: what weaknesses and strengths it has, why they implemented it, how they have interpreted this law. To answer this I have used a qualitative method called phenomenography and done interviews with five college library managers.

The study's aim is to create an understanding for the question why Sweden in 1921chose to create its own classification system for public libraries instead of adapting e.g.the Dewey-system which - at this time - was internationally we11 spread. It examines thesocial changes which proceeded the creation of the Swedish Library Association (SLA)in 1915 and discusses in depth the work of the committee appointed by SLA to createthe classification system. Special interest is also given to the relation between SLACSand the Dewey-system.The study shows that the main influence on the codttee's work was the formerSwedish tradition of classification practice. The Dewey-system was seen as inappropriateto adapt in the Swedish libraries because of the vast changes that wouldhave to be done, and the fact that the decimal notation was practically unused in anylibraries in Sweden.From a methodological point of view, the study tries to apply a critical hermeneuticalapproach as developed by Paul Ricoeur.The study contains an extended English summary..

The participants in our thesis were given ten motivational factors to rank according to what they believed motivated them the most.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

När ett system införs, spelar det ingen roll hur god funktionalitet det har, om användarna av någon anledning inte kan eller vill använda det på ett effektivt sätt. I första hand bestäms användbarheten hos ett program av egenskaper hos detta och hos de aktuella användarna. God användbarhet beror av acceptans från användarna, kompetens hos användarna och användarvänlighet hos systemet.För att undersöka hur man kan uppnå hög användbarhet och därmed en hög grad av användande vid införande av ett nytt system, har vi gjort en undersökning av användbarheten och användandet av ett system vid Landstinget i Östergötland.Våra slutsatser visar på att utbildning och information är mycket viktiga faktorer för att uppnå hög användbarhet för ett system. Många har en motvilja mot att använda datorer och problem med att se vilka fördelar ett införande av ett nytt system kan medföra, något vi anser kan lösas med bättre utbildning och information. Trots att teorier om användbarhet funnits i över tio år, har vi funnit att det forfarande inte tas tillräcklig hänsyn till de grundläggande faktorer som påverkar användbarheten vid införande av ett system..
