Vi har från och med 2011 en ny läroplan för grundskolan som betonar användningen av digital teknik i matematikämnet mycket starkare än den tidigare läroplanen från år 1994. Situationen i skolan av idag på detta område är inte i fas med kravet från den nya läroplanen. Det behöver utvecklas en ny praxis för användandet av digital teknik i matematikundervisningen. Med den studie vi här gjort har vi velat få handgriplig information hur en introduktion av ett gratis dataprogram, GeoGebra, kan tänkas fungera för nionedklassare. Studien är en tredelad fallstudie med 1) ett undervisningstillfälle; 2) ett uppgiftslösningstillfälle; och 3) ett intervjutillfälle.

Den här studien kommer belysa om kulturjournalistiken i tre svenska dagstidningar har förändrats till följd av deras digitala publicering och i så fall hur. Denna utveckling bör ses i en större kontext med en utmanande ekonomisk situation för dagspressen, färre prenumeranter och därför även vikande annonsintäkter, utöver ökad konkurrens från Internet, sociala medier och webbtidningar. Webbpublicering har gjort det möjligt att ständigt mäta hur läsare tar till sig artiklar, om texter blir klickade och om de blir lästa. Genom kvalitativa intervjuer med tre kulturredaktörer på tre olika dagstidningar kommer denna studie belysa kulturredaktörens publicistiska ställningstaganden. Analysen tar upp en rad frågeställningar som gäller det journalistiska innehållet, språk, typ av textgenres som publiceras, sätt att skriva, förhållningssätt hos kulturredaktören samt olika sätt att arbeta journalistiskt, och undersöker om det var något av detta som framstår som en extra tydlig utveckling i relation till digital publicering.

Too much attention has been given to mainstream approaches in performance management and management accounting research, without taking in to account changes in the environment with the rapid growth of online retailing. This paper evaluates how and/or if performance management differs in online contexts by using a conceptual model developed by Ferreira et al (2009). The model and its components are tested on three multichannel- and six e-commerce businesses. The result and its analysis is commented on by two e - commerce experts. The result shows that the operation method of the models twelve components do not differ in terms of work methods in online and offline contexts.

This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

Genom litteraturstudier samt praktiskt arbete med förbättringar av programvaran File Secure har ett antal lämpliga designmönster för konfigurationshantering i Java identifierats och applicerats. Den typ av konfigurationshantering som här avses innefattar inläsning från en databas till en objektrepresentation, samt ett grafiskt gränssnitt som låter användaren modifiera datat. Det antas att mängden data är förhållandevis liten, vilket har gett upphov till vissa förenklingar. Resultatet av arbetet presenteras i form av ett mönsterspråk för konfigurationshantering, innefattande designmönstren Domain Model, Active Record och det befintliga mönsterspråket Model - View - Controller. Detta kan appliceras i många olika sorters system..

AbstractIn this text the attitudes towards and using of blogs in teaching Swedish toteenagers will be explored. The results are based on a survey made amongst 17teachers and 58 students from all over Sweden. The end results show that theusage of blog still hasn?t found a permanent way into the classrooms, but has anappeal to and is being used by predominantly younger teachers both, male andfemale, with a positive response from students regardless of gender. Theconclusion is that using web tools like the blog is an easy first step for schools toconnect to the digital society of the 21stcentury and take advantage of the perksavailable in the digital classroom.Svensk titel:Blogg + Svenska =Sant? ?

Denna studies syfte är att försöka förstå och diskutera den digitala mobbningen utifrån det mediasamhälle vi befinner oss i. Frågeställningarna som är grunden för studien är: Hur kan vi förstå digital mobbning? Hur kan denna förståelse leda vidare till metoder för att angripa problemet? Hur upplever pedagoger respektive elever den digitala mobbningen? Vad säger lagen om mobbning? Vad kan vara viktigt att tänka på i samband med Internet? Studien bygger på kvalitativa och kvantitativa undersökningar gjorda på två olika skolor. Den kvantitativa undersökningen bestod av enkäter som delades ut i tre klasser i år sex. Den kvalitativa undersökningen bygger på intervjuer med två pedagoger knutna till dessa klasser.

This study focuses on trying to understand the attitudes of people born in the 1940?s concerning their view on social media. This 1940?s group has been growing on the social networks such as Facebook, but their usage is not active. Therefore, the purpose of this report is to understand in what way they are affected by the using of these platforms.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

Developed model for easier animal welfare assessment- with examples from dairy cows in loose housingAnimals in captivity are completely dependent on human care. If captive animals are prevented from exhibiting their natural behavior, they may suffer. Animal welfare inspectors, who insure that the animal welfare legislation is followed, use a checklist to assess the situation in the husbandry. This checklist contains only two levels of assessment, which may result in a lack of detail in the assessment of the husbandry. The objective of this report was to develop a more detailed model that provides an overview of the situation in husbandry.

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
