Resan som förändrar : En studie om volontärturismens påverkan på barnhem i Tanzania

Background: Today, the tourism sector is one of the economically fastest growing sectors in the world. Volunteer travel is a type of service that is gaining in popularity and a number of tour operators organize these trips. Few aid agencies engaged in volunteer activities and therefore the interest in volunteer travel is caught by tour operators. These tourists travel in small groups and interact with locals. Today fifty million children in Africa are orphaned and Africans struggling with the care of these children by founding orphanages.Research questions:What does volunteers contribute with during their stay at orpahanges?What view does volunteers and orphanages have on volunteer tourism?Purpose: The purpose of this paper is to examine the positive and the negative effects that volunteer tourism contributes to orphanages.Method: The study is based on a qualitative approach with semi-and unstructured interviews, observations, and email interviews.

Miljöcertifieringssystemet Miljöbyggnad : Inverkan på utformningen av ett kontor

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

Gröna broar : ekologiska, sociala och estetiska tillgångar

The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.

OMSTÄLLNINGSBEREDSKAP - En kartläggning av omställningsberedskap i kommunala förvaltningar i Västra Götalandsregionen

The study focuses on mapping how well prepared the counties in the west region of Sweden is in case of restructuring. The study explores what kind of activities and routines that contributes to prepare the organization for restructuring. The study also aims to investigate the effect of precedent restructuring, and if the counties who experienced restructuring are more prepared than others.The research within the field of restructuring characterizes of an evaluating nature and the focus has been after the restructuring occurred. There have also been a lot of studies of the negative consequences on individual and organizational level. Since downsizing is a frequently used method by management despite its consequences is it important to investigate how organizations can learn and thereby be more prepared for restructuring.

Ungdomars mognad, en avgörande faktor : en kvalitativ studie inriktad på en grupp föräldrar gällande tillhandahållande av alkohol till sina barn

Our purpose was to shed light on how parents act in respect of providing alcohol to young people when they ask for a taste of home, or wish to bring alcohol to such a party. We used qualitative interviews and the results show that some of the respondents think that it may be acceptable to provide alcohol, while some do not. The results also show that the respondents think that parents are important as a model for the young. They could not purchase alcohol for the purpose of giving it to the young but only if alcohol is available at home. The reason for this behavior is the parents' assessment that the young person demonstrates a level of maturity for his age that they are presumed to be able to handle a small amount of alcohol.

Introduction: Analysts worldwide valuates stocks and companies by using different valuation models. The models are used to calculate how much public company?s stocks are worth and to identify whether stocks are over- or undervalued.  Objective: The objective of this essay is to study which valuation models are mainly used by financial analysts in Swedish banks. The purpose is also to study how reliable these models are considered. Method: The empirical study is based on a qualitative approach through interviews with financial analysts. The study includes both primary data (interviews) and secondary data (literature, websites and scientific articles)Theory: The theory chapter includes methods of analysis (fundamental and technical analysis), Valuation models, components of valuation and an example of a valuation with the Discounted cash flow model. Empirical study: The study includes a qualitative research that consists of interviews with financial analysts.

En fordonsförares upplevelse av accelerationer som grund för en effektiv simuleringsmodell

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
