This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.

Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.

The increasing significance of social economy as a concept is linked to general global processes such as the crisis of the welfare state, neoliberal globalization, anti-bureaucracy tendencies and decentralization, but also to a growing political interest in human rights and social development. In Sweden the idea of the social economy generates wide support within civil society as well as within the government and across party political boundaries. Furthermore, what is problematic in this context is the fact that the discussions on the subject tend to be relatively uncritical and often it seems as if though the expansion itself is the main objective. The emphasis on cooperation and the third sector in terms of welfare production implies a set of risks in relation to state responsibility, democracy and the autonomy of civil society. This paper aims to explore those risks and how they can be dealt with within the Swedish context..

Den 14de januari 2003 startade en av Thaksins mest häpnadsväckande populistiska kampanjer, vilket är ämnet för min uppsats.I ett tal till en stor samling befattningshavare deklarerade han att regeringen skulle genomföra en kampanj där alla droger i Thailand skulle elimineras på endast tre månader.De följande tre månaderna mördades över 2,200 människor, varav ett flertal enligt vittnen var helt oskyldiga, och merparten enligt Human rights watch (HRW) lättare droganvändare. Flera Människorättsorganisationer och kritiker misstänker att en stor del av dessa dödsfall var utomrättsliga avrättningar utförda av, eller på uppdrag av statlig polis. Trots skarp internationell kritik fortlöpte kampanjen utan större offentliga protester i Thailand.Thaksin annonserade i slutet av kampanjen drogkriget som en stor framgång. Han vann ett år senare sin andra jordskredsseger..

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.

During the last few years the countries in the African continent have experienced an enormous increase in female politicians on a national level. Rwanda is even the country with the highest number of female politicians in its parliament in the world. Despite this development in Africa, the quantitative research on women's political representation in the world has not yet paid attention to the situation there. Some of the surveys that have been done have even excluded countries that do not fit the homogeneous pattern ? which is precisely the problem with African countries ? for it to be possible to explain the situation with existing theories.The intention of this paper is therefore to, with all of the 53 African countries included in the study, examine whether the already existing explanatory factors regarding women's political representation also can be applied to an African context to explain the situation there.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.

This paper aims to determine what is decisive for localisation of production units when a company engages in offshoring. By performing a case study on Electrolux and comparing the results with theoretical literature we discuss the implications for manufacturing companies in general. To facilitate a structured analysis we have developed a model dividing the localisation decision into five perspectives and four geographical levels. We have found that the determinants of localisation vary depending on the geographical level of the decision process. Since all geographical levels are interconnected, the analysis needed for a decision on all levels simultaneously is very comprehensive.

The purpose of this study is to understand encounter by individual depictions of meetingsperceived by social workers and clients in social services. Thus, we want to understand moreabout how clients and social workers as actors encounter each other in meetings in the socialservices. The study also aims to understand how the two actors affect each other in this typeof interaction and whether there are other influencing factors. We conducted a qualitativestudy by interviewing informants with semi-structured interview questions. The informantswere comprised of three social workers and eight clients.

Mergers and Acquisitions have become more and more in common knower days among the companies. Factors that might influence could be such as power of competition or it could even be the aim of new strategies of the company. In mergers is it not only the buildings and the physical objects that is put together, also the human beings within the organization are put together. Each person contributes to the culture, which makes the situation more complicated. In making a merger successful, it is important to pay attention to the organizational culture.

Background: Long-term stress can lead to reduced health among nurses which can result in impaired quality of care. Stress in nurses' work needs to be studied in order to prevent stress and impaired quality of care. Aim: The aim of this study was to describe nurses' experience of occupational stress and factors that contribute to occupational stress. Method: The method used was a literature review. Results: The analysis resulted in five themes which describe nurses' experiences of occupational stress and factors that contribute to occupational stress.

In order to produce grain in an economically rational manner numerous decisions have to be made. One of these decisions is what tillage system to use. The cost of the tillage system is a large part of the total cost in grain production. Different tillage systems result in different distribution of fixed costs, operating costs and timeliness costs. The price of the produced grain and cost of inputs also affect the best way to produce grain.

Previous research shows that small workplaces more often discriminate immigrants during the process of hiring new employees than larger workplaces, and usually explains this result by referring to structural factors. At the same time, previous research also shows that self-employees tend to have different personality traits than other people. Could it be the case that the higher discrimination among small workplaces can be explained at an individual level? I examined the hypothesis through OLS-regressions using a survey called Employment, Material Resources, and Political Preferences. The results showed that people working at small workplaces tend to have more negative attitudes towards immigrants than people working at larger workplaces.
