There is much literature covering strategic change under different circumstances but very little concerning how companies act strategically under sudden and radical changes to market conditions. Based on three different events (the terrorist attack in the USA September 11th 2001, the Tjernobyl accident April 26th 1986 and the Islamic revolution in Iran 1979) with such radical changes as a result we chose three companies that were affected (SAS, Asea Atom and Atlas Copco). The result of the events that were studied in this thesis is extremely unusual to their character. The events themselves were sudden and of a temporary nature but the results were long term changes of market conditions. Through personal interviews the authors have tried to establish how the companies have perceived the events and how the top management has strategically handled the situation.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.

Within process or manufacturing industries, the production of goods and services or the products themselves may have negative side effects such as pollution. An important task for environmental policy is to control and limit these pollutions, for example via regulatory measures. Although, the efficiency of such measures vary greatly between different industries and an increasingly important task for environmental policy is then to encourage companies to engage in environmentally motivated innovation. Governments can utilize other measures than regulation to indirectly decrease pollution. This thesis aims to analyze such activities and how it affects the innovativeness of wastewater treatment, refrigeration and automobile manufacturing industries.

The employer is obligated to call for negotiation on his own initiative, before he makes decisions in questions, which constitute important changes of the employer?s business or of the worker?s working conditions and terms of employment. The obligation to negotiate is reserved to the organisations, which the employer has collective agreements with. But what does the concept of important changes mean? What areas are included in the concept of important changes, according to legal framework and case law? How extensive is in fact the employer?s obligation to negotiate? The purpose of this report has been to seek answers to the above-mentioned questions, through partly describing how the employer?s obligation to negotiate has developed, and partly describing how the codes of negotiations in the Employment (Co-Determination in the Workplace) Act of 1976 are raised and applied.

The purpose of this report is to analyze and evaluate non-profit organizations way of working with social media within the organization, from a marketing perspective. We have made observations of three organizations and completed a series of interviews with representatives within the organizations.In the report we came up with five factors that are necessary for non-profit organizations in order to receive long term donations with the use of social media; Trust, awareness, involvement, interaction and Word of mouth marketing.Our result shows that the organizations have realized the potential and benefits of using social media, but have not come very far in the process of using it properly. Our conclusion is that social media can give assumptions for long term donations, if the organizations use a customer perspective and give their customers added value..

A total of 119 individuals participated. There were 70 female and 49 male subjects, aged 4 to 80 years (M=34,3).

The purpose of this thesis was to analyse if the six month rule in chapter 3 § 9 part 1 in IL is compatible with EU law regarding the free movement of employees and in case of discrimination whether the rule can be justified. First of all the retroactive salary for an unlimited taxpayer and during the period of income earning a limited taxpayer who later became unlimited taxpayer will be analyzed in order to determine if they are considered to be in a comparable situation. An unlimited taxpayer is subject to taxation in Sweden for all of his incomes regardless their origin. However there is an exception according to six month rule, which implies that physical persons who stay abroad due to their minimum six months employment are in Sweden free from their incomes earned abroad if they are taxed in the country of employment. Tax exemption is applicable even if the payment from an employee working abroad is made retroactively.Article 18 EUFF states a general prohibition of discrimination on the grounds of nationality.

In the society of today more and more employees are reported sick due to illness caused by their place of work. A lot of employees are stressed in their daily work and because of that they get mentally exhausted. These common occurrences are a part of the psycho-social work environment and it is the employers responsibility to avoid them. To rehabilitate an employee is often very expensive and takes a lot of time. Focusing on preventing illness in the work environment, instead of repair when illness is a fact, is an advantage both for the employers and the employees.The purpose with this essay is to illuminate the responsibility that the employers have to prevent psycho-social illness in the work environment.

Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.
