Den fysiska resebyråns framtid : En studie om de fysiska resebyråernas förändrade betydelse på resemarknaden

Purpose:  The purpose of this paper is that from the physical travel agencies perspective try to see how they perceive their future, knowing that the booking on Internet has increased.Problem: What are the prospects for future development of the physical travel agency? Has the technological development affected the physical travel agency and forced it to change its role and meaning?Method: This paper has a qualitative approach. Interviews have been made with employees on physical travel agencies to try to reach a deeper understanding and thereafter be able to give us an understanding of our problem.Conclusion: The physical travel agency has been given a new role as the employees are no longer seen as sellers but more regarded to as consultants. The travel agency has become more of an information bank than just a shop where travels are being sold. Despite this change, we believe that customers will continue to visit the physical travel agents because of the unique knowledge and services they can provide that Internet not yet can offer.

The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Lär man sig något av idrottsundervisningen? : En studie om gymnasieelevers lärande i Idrott och hälsa A

The purpose of this essay was to study what students at the upper secondary levels thought that they learned in physical education and if there were differences between girls and boys learning. The purpose was also to study different factors that could affect the learning and to show how curriculum and prior research relate to the students learning. In this essay we used the three aspects of health that are mentioned in the description of physical education: the physical, the social and the psychic. The study was based on a quantitative research where 165 students answered questionnaires about their learning. Our research showed that the students did not get the knowledge that the A-course in physical education should provide and that the goals for the course were not accomplished.

Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell

The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..

Svensk invandringspolitik i förändring : En kritisk granskning av åtgärdsförslag inom SOU 2006:79 för en ny politik

The findings of the study are multiple.

Utveckling och utvördering av statistiska metoder för att öka träffsäkerheten hos lokala vindprognoser

Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.

Vilken påverkan har fysisk aktivitet på lärande

ABSTRACTThe purpose of the study was to examine, from the point of view of former research findings, what impact physical activity had on learning. I chose to make an explorative/inductive research, to get as much knowledge as possible from the studied presentation of problem, not to limit myself to a specific research theory. The result proved, that school personal and student experienced many positive effects from daily physical activities. The pupils were more pleased. There was more piece and quiet in the classroom.

Beteende på offentliga platser

Several theoretic and environmental psychological models establish a connection between the environment and the reactions of humans and the research support that there is a mutual influence between individual, environmental and behavioral factors. You often assume that a person both can influence and be influenced by the surrounding environment. This is evident, but it is less obvious how a given physical design influence people?s immediate behavior in the city. The aim of this study was to investigate if the physical design of a place influences people in an urban environment and to investigate how the behavior is influenced.

Från top down till bottom up : - Att förklara och utvärdera psykosocialt arbete inom hälso- och sjukvården

Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments.

En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

Fysisk aktivitet : två skolor, två arbetssätt, en rektor

The purpose of this study is to examine how two different primary schools with the same school management district work with daily physical activity. We have chosen to conduct our investigation based on interviews. Through the interviews, we can highlight the teacher´s and principal´s interpretations of the concept regarding physical activity and find out the school´s arguments and working methods for pupil´s physical activity. These two schools work with physical activity in two different ways and the study describes the teacher´s and principal's choice of approach. Since our training is directed towards the younger ages, school years 1-3, we chose to interview teachers who work in these classes.
