Fonologiskt korttidsminne hos tvåspråkiga barn med och utan språkstörning
Repetition of Non- word (make- up word that has not some semantic content) has been proposed as a reliable index of phonological memory in children with language impairment (LI). The aim of this study was to find out the possible similarities and differences concerning phonotactic non-words and working memory in 18 bilingual Swedish-Arabic children with and without LI ages 4-6 years. The investigation was undertaken by conducting three tests including NEPSY, WPPSI-III and a Word repetition test. The results showed that there are not significant differences between the two groups regarding various parts of NEPSY. On the other hand the results showed two significant differences in WPPSI-III regarding Picture categories and Word repetition tests for Swedish Non-word.
Ytstridsfartygs ballistiska skydd mot finkalibriga projektiler
This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..
Skiljer sig riskuppfattning och riskhantering mellan kvinnliga och manliga privata skogsägare? : en enkätundersökning bland privata skogsägare i Sverige
As a forest owner you always have to consider hazards and uncertainty when planning your forestry actions. The aim with this report is to test my hypothesis that there is an overall difference between men and women when it comes to perception, estimation and management of hazards/risks in forestry. I will look into if there are differences in how men and women estimate risks in production forestry from an economical point of view. The aim is also to look into if there are differences between male and female private forest owners, in how they perceive and manage hazards in connection with a possible climate change.
To fulfil this aim, an inquiry survey was undertaken in three different areas of Sweden, two areas in the south and one in the north. But in this report I have evaluated the three areas as a whole.
Har en goodwillnedskrivning någon effekt på aktieavkastningen? : En eventstudie av bolagen på Stockholmsbörsen
On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.
Utlandsetableringar & aktieägares förmögenhetsvärde : En eventstudie om utlandsetableringars påverkan på aktiemarknaden
The aim of this study is to examine the market reaction when information about a company?s foreign direct investment is announced and how that affects the shareholder?s value. Also of interest is whether the market reacts differently depending on which country the investment is established in and which mode of entry is used. This will be achieved by using an event study approach. The selection that was used consisted of 206 companies registered on the Nasdaq OMX Nordic homepage, which had during a time period stretching from 1999 to 2009 established a foreign direct investment in the regions BRIC, Europe or the USA using the mode of organic growth, joint venture or acquisition.
LUS- och skrivutveckling
The purpose of this study was to compare reading development assessments with writing assessments to create an understanding about the relationship between the reading and writing ability of children. Another aim of the study was to look at other factors that cohere with the ability to read and write, such as background and socio-economic status. Our hypothesis was that explicit instruction in writing is necessary to develop good writing skills. We chose to conduct a quantitative study containing an inquiry, a dictation and a writing task. We compared our results with reading assessments based on a reading development schedule (LUS).
Förbättrad balans hos kvinnliga innebandyspelare efter fem veckors balansträning i relation till skaderisk. : En kombinerad litteraturstudie och empirisk studie
Introduction: Balance is a complicated term which includes a static, dynamic and functional part. These parts have, during a long period of time, been included into the existing training programs through several different balance exercises, which aim to prevent sports injuries mostly focused on the knee and ankle. In floorball these injuries are common and a sports injury prevention program is required.Purpose: The purpose is to explain the balance term and relate it to injury prevention training and the existing theories. A second purpose is to see whether five weeks of balance training increases the balance ability in female floorball players and thereby increase the test values in the two tests.Method: Twenty female floorball players participated in the study and were divided into a training group and a control group. They performed a Star excursion balance test (SEBT) and a Multiple single leg hop stabilization test (MSLHST) before and after a five week training period, containing exercises of balance.Results: The training group showed improvement after the training period, however only one significant result was found.
Does Party Politics Matter? - En hypotesprövande studie om USA:s partipolitiska position till europeiskt säkerhetssamarbete
In his recent article Professor of International Affairs Charles Kupchan claims that Party Politics has become increasingly important for American Foreign Policy since the end of the Cold War. This assertion makes it valuable to assess how the substance of the Foreign Policy differs between the two American parties in various cases and if this difference is characterized by consistency or by change. In this thesis I examine these Party positions in relation to the European Security Policy.In order to examine this I compare the positions of the Democratic and Republican Parties? policy concerning both the European Defence Community (EDC) and the European Security and Defence Policy (ESDP). The purpose of this thesis is to examine the hypothesis that the Democratic Party to a higher extent than the Republican Party is more concerned to maintain good relations to Europe respectively EU.The results show that there are small indications that my hypothesis concerning the two parties is valid.
Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?
Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

Malmöspanaren - En digital plattform för deltagande förvaltning av Malmö stads cykelvägnät
In this project we have explored digital tools for service management on the bicycle paths of Malmö. This was done through the participation of citizens in order to attempt to discern how such interactions can be eased using a mobile app, as well as how this app can be designed in order to appear trustworthy with user friendly interactions.
We have explored this field by using goal-oriented design through interviews, prototyping and user tests. We have created a digital prototype as a possible solution for how the interactions can be done.
Throughout the process interviews were held and user tests with selected members of the user group. To explore the concepts we have used paper prototypes in order to establish the design and then defining the interactions with the help of a digital prototype.
Finally we have concluded that a general app for bikers in the city would be functional and that a longer study in the effects of such an app would be interesting as a continuation of this work..
Uppgradering av biogas med aska från trädbränslen
The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt
The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.
Androidvetenskapen och den kusliga dalen: Japanska robotar som forskningsplattformar och filosofiska leksaker
The primary aim of this essay is to analyse, contextualise and problematise the scientific and technological goals of android science. The starting point of this investigation is the history of automata and man?s attempts to recreate himself by technological means. Drawing on the no-tion of boundary work this essay also analyses the efforts of the proponents of android science to establish and demarcate a new interdisciplinary field. A secondary aim of the essay is to evaluate the scientific support for the uncanny valley hypothesis and to investigate how this hypothesis contributes to android science.
