Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

Samband mellan luftföroreningar och klimatfaktorer - en statistisk unersökning

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

Hälsobeteende bland sjuksköterskor och undersköterskor : En studie om oregelbundna arbetstider på Ålands hälso- och sjukvård

In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..

Svenska myndigheters användning av sociala medier : Vilka mål har myndigheterna med sitt användande av sociala medier samt hur mäter myndigheterna effekten av sitt arbete?

Swedish authorities have been dealt a mission by the Swedish state, where each agency works on the basis of their assignment. Communication has become more and more important for authorities, there are several reasons for the use of communication and they may differ from authority to authority. Some authorities claim that the purpose of the communication work is to create awareness and recognition among citizens. A communication form that has become increasingly important for government agencies is social media, according to the government authorities should implement social media in their communication work because it is very important that the authorities are available where the citizens are. Previous research has focused on the risks and opportunities that the social media generates for the public sector.

Investering i spannmålstorkning och lagring på gårdsnivå : en jämförelse av ett silotorksystem med omrörare och en konventionell anläggning

The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season. An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.

En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet

The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering

In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

Effekten av formativ bedömning : En studie kring effekterna av formativ bedömning i anknytning till kunskapssyn, problemlösningsförmåga och attityd

This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.

Kim Jong Il - Docka eller dockmakare?

This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..

Dygden och dårskapen : En studie av mamsell Malmstedts översättningar från franska och latin

Anna Maria Lenngren (ne?e Malmstedt, 1754-1817) was an eminent poet in Sweden during the 18th century and she is still known as one of Stockholms Posten?s sharpest satirists. The early stage of her career as a translator, when she was recognised as ?mamsell Malmstedt?, had a great impact on her following work, which has been largely neglected. This master?s thesis analyses her largest translations: Lucile (1776), Zemire och Azor (1778), Arse?ne (1779), and Dido til Eneas (1778), in comparison with their originals.

Syftet är att belysa den ekonomiska aspekten mellan de två metoderna. Samtidigt undersöker studien om heuristisk utvärdering är en metod som lämpar sig som beslutsunderlag. Studien är genomförd på ett tryckeri där tryckeriets IT-system har testats och utvärderats utifrån de två metoderna.

Cupsystemet - En kvalitativ fallstudie av en mobil webbtjänst

The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments. The differences in way of labour pre and post the system have been analyzed and through interviews the value of these changes have been assessed. The results achieved in the thesis are as follows, the presented mobile web service does not only decrease the total work effort made by the tournament officials it also speeds up their work.

Redovisningskonservatism -En studie om redovisningens försiktighet i Sverige

This study aims to measure the effect of accounting conservatism and to identify thebusiness activities causing firms to undervalue owners? equity. To estimateaccounting conservatism, we have followed the hypothesis that no firm over time cangenerate a return greater than its cost of equity, i.e. CAPM. Thus, if a firm in factgenerates an excess return over time, we assume that the excess return is an estimateof accounting conservatism within that firm.The hypothesis originates from the corporate valuation model ?Economic ValueAdded®? which tries to adjust for accounting bias.
