AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

The market of fruit and vegetables develops continuously to become tougher and more complex. The fast development makes it difficult to keep up with all the changes. This is the case for apples and tomatoes. The purpose of this work is to explain what the trade routes are like for Swedish imports as well as the Swedish production of tomatoes and apples, both in the present and the past times. There is also an ambition to create comprehension of the trade routes.

This report describes how we made a dynamic website combined with staticalweb pages and a web shop for the Swedish company Tyger & Ting.The employer Tyger & Ting wish to run a working web shop on their site butthey want to keep their old system of updating pages with their old applicationfrom Intellyweb1, which creates statical HTML pages.The goal of this exam paper has been to learn to create a functional web shopwith user friendly layout and appealing design and also to take orders andfulfill wishes from a real employer.The report is describing how Intellyweb?s application and its statical web pageshas been implemented on a dynamic web page. The report does also describehow this site has been build and how the problems with the coding have beensolved. The coding has been made with HTML, PHP and MySQL. CSS hasalso been used.

This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

The Functional Resonance Accident Model is a method developed to analyze complex systems for the purpose of accident prevention. In FRAM-analysis a visualization of the complex system is created as an aid for identifying points of interaction in the system where the risk of accidents is high, and to determine where preventive measures are to be placed. FRAM Visualizer is a computer program developed as a tool for creating such visualizations.Many usability problems have been identified in FRAM visualizations created both manually according to established method and by using the FRAM Visualizer software. The purpose of this paper is to give a basis for how FRAM visualizations can be improved in accordance with usability criteria for use in future qualitative studies.The author suggests alterations to the FRAM visualization to resolve usability issues identified in previous articles and to achieve usability goals derived from visual communication theory. The design process is guided by established design principles.

Denna uppsats undersöker en informationskampanj från Fair Trade Center (FTC) som drevs under hösten 2012 under namnet A wage to live on. Uppsatsens syfte är att utröna om Fair Trade Center har nått ut med sitt budskap till media och söker detta svar genom fyra frågeställningar; Har FTC nått ut med sitt budskap till de undersökta medierna (Aftonbladet, Expressen, DN och SvD)? Vilket budskap har FTC med sin kampanj (utifrån mål och material)? Verkar Kalla Faktas reportage ha påverkat medias respons? Är FTCs budskap samstämmigt i mål och material? Fokus för uppsatsen ligger på vecka 43 2012 då detta var fokusvecka för kampanjen. Mot en bakgrund kring teorier om budskapsstrategier, målgrupper och olika mål och tidigare forskning kring framgångsrika kampanjer har jag genom retorikanalys som huvudsaklig metod gått igenom utvalt material. Materielet består av Fair Trade Centers egna pressmeddelande och debattartikel samt utvalda tidningars respons under fokus perioden.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

The aim of this study has been to analyze how society is constructed in the workbook Möte med människor från andra kulturer, a popular material within the ?cultural competency? industry. The analysis has largely been carried out from the perspective of a pedagogy against oppression as it has been outlined by Kevin Kumashiro. I have found that the material combines discursive movements, which in complex and hybrid ways deconstruct, decenter, recenter and reproduce stereotypes and norms, through its normative language and pedagogy. A language constructing culture as cleanly demarcated, static and homogenous.

Venture capital-bolag tjänar sina pengar genom att investera i företags tidiga utvecklingsskeden, för att senare sälja sin del för en större summa än de investerade. Detta gör att tillfället då venture capital-bolaget säljer är väldigt kritiskt för hur mycket de skall tjäna på sin investering. I detta skede spelar självklart en mängd faktorer in på vilket pris som erhålls. Enligt samtal med flera venture capital-bolag har vi identifierat en faktor som verkar ge extra stora problem; huruvida de skulle genomföra en produktlansering av företagets produkt före de säljer eller om venture capital-bolaget skulle vänta med lanseringen och sälja först. Syftet med uppsatsen är att undersöka hur venture capital-bolags exit via trade sale påverkas av produktlansering i portföljföretag och därigenom ge svar på om venture capital företag ska göra exit före eller efter att portföljföretagets produkt lanserats.

A majority of the payments that are carried out today are executed through the electronic payment systems. Payments that are executed through these systems are administrated by payment service providers, these providers are, in general, banks. In spite of the socio-economic importance of payments and payment intermediation, there is an uncertainty regarding the legal status of payments and payment intermediation. Some describe payment intermediation as transport of means of payments, while some describe it in terms of claims and intermediation of information. There is, in other words, a need for clarification.

I nära tio år har främst amerikanska placerare utnyttjat strategin carry trade för att skapa positiva avkastningar. Strategin innebär att lån tas på en marknad med låga räntor för att sedan placeras på en annan marknad med högre räntor. Det är främst de japanska och amerikanska räntemarknaderna som har använts.Syftet med uppsatsen är att utreda om det går att få en positiv avkastning vid carry trade-affärer. Vi kommer även att belysa vilka risker som uppstår vid dessa investeringar, samt undersöka vad som kan göras för att minimera de risker som uppstår. Genom att studera andra länder med betydande räntedifferenser vill vi även utreda om denna strategi går att tillämpa på andra ränte- och valutamarknader än Japan och USA.För att uppfylla syftet har en kvantitativ studie genomförts baserad på sekundärdata, där vi skapat olika fiktiva affärer över tre tidsperioder för att kunna räkna ut och jämföra avkastningar.

The aim of this thesis is to describe the development of profitability and capital structure in Swedish quoted companies during the period of 1990 to 2004. Further, the aim is to determine the relationship between profitability and leverage in order to conclude whether the choice of capital structure supports the pecking order theory or the trade-off theory of capital structure. The findings show that return on assets fluctuates between 3 and 11 percent and that return on equity fluctuates between 3 and 22 percent during the period. Further, the leverage and the cost of debt have decreased. This indicates lowered financial risk in Swedish quoted companies in the period between 1990 and 2004.

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.
