The purpose of this study is to investigate childrens possibilities to retrieve information by searching in searching engines designed for children. Two such search engines are examined: Yahooligans and Kids Click, both of which index pages in English only. I have compared Yahooligans with its equivalence for adults; Yahoo, by evaluating the retrieval effectiveness. Some functions in Kids Click and in Yahooligan are investigated. Seven class room studies are described in the prior research chapter.

The purpose of this project is to survey the presence of folk expressions, i.e. proverbs, proverbial expressions, wellerisms and familiar expressions, in some of the realistic children?s books by Astrid Lindgren. The purpose also includes the study of the contextual and pragmatic functions of the expressions as well as how the expressions are integrated into the text by the change of the formulaic standard structure. The contextual and pragmatic function concern when, how and why the expressions are used and who the users of the expressions are.

Political disenchantment and detachment is proven to be growing in well established democracies. This development brings along concerning behavior regarding general political participation. Fewer citizens participate in elections, parties are losing members, and the trust in politicians is steadily decreasing. IDEA (Institute for Democracy and Electoral Assistance) has been registering voter turnout worldwide for the last 60 years and their publications show a decline in voter participation since the 1980s.During the same period of time another development has caught attention, namely the fast progress of the medium Internet. The new generation of Internet functions is called Web 2.0 and allows users not only to create content, but also to interact with each other.This dissertation aims to explore the possibilities emerging when integrating Web 2.0 in political processes.

Homework is and has always been a part of school work. It may take a lot of time from the pupils? leisure. Despite this, you cannot find anything written about homework in the curriculum. How can this be? Is homework necessary and what is its function?The purpose of this study is to find out how a few teachers in primary school reason about homework.  What are their attitudes towards homework and what functions do they see?To get an answer to this I studied literature and research reports, and did four qualitative interviews with teachers who teach grades 1-6.The results show that all the teachers give homework to their pupils, but their opinions about homework differ.

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

Two of Swedens´s major banks, SEB and Handelsbanken, which appears in the same industry and have similar strategy. Both banks can achieve a similar result despite the fact that their reward system looks quite different. An issue that arises from this observation is the relative reward system to the rest of the economy control system.Our purpose of this paper is therefore to examine the reward system in the organization's financial management systems. We wonder if the reward system may be a function of economic control system, or part of the system, or perhaps made independent of the system and then gradually adapted?In our study, we choose to assume a reward system has three functions to manage, motivate and compose the employee group.

The public library´s overall purpose and legitimacy is analways relevant subject for discussion in Library andInformation Science and in public debate on libraries.Libraries are a part of a bigger societal context and are thusinevitably influenced by societal changes. In this thesis wehave studied different roles and functions of the publiclibrary, as seen from documents published by one specificpublic library in Malmö - Garaget. As basis we have usedan analysis model of the library in the knowledge andexperience society made by Jochumsen, HvenegaaardRasmussen och Skot-Hansen (2010). Our purpose has beento examine which ideas and notions on the functions of thepublic library that can be found in Garaget?s documents andin the model ? and to discuss them from a discoursive pointof view.

The hillforts of Bohusl?n are numerous, yet few have been studied, leaving gaps in our understanding of their dating, morphology, and connections to nearby prehistoric sites. With the help of settlement archaeology, the aim of this study has been to analyse three hillforts on Hisingen and answer these questions. This was done by observing the location and morphology of the hillforts and by analysing the age and functions of nearby prehistoric sites within a kilometer of the hillforts. The results indicate that Bj?rlanda 22:1 and Torslanda 56:1 were likely ritualistic enclosures, while Torslanda 15:1 had defensive functions.

The object of this study is to examine the effective functionality of an OPAC-system while a few participants interacted with the catalogue. I?ve used Carl Martin Allwood?s (1998) four designed usability factors to be able to estimate the effective functionality of the online catalogue. Theoretic basis is Human Computer Interaction together with Allwood?s four defined usability factors.

En mycket stor del i alla nybyggnationer är byggandet av innervägg där gips är huvudkomponenten. Denna process upptar en stor del av den totala byggtiden och är därför intressant att studera samt försöka förbättra. Den här studien syftar till att genomföra en totalkostnadsanalys av ett traditionellt innerväggssystem för att sedan jämföra det med införandet av konceptet PL Wall, som är en klickvägg av gips. .

The design process of an interaction design student is mostly collaborative and computer oriented. Based on this, it?s hard to believe that we have not yet found a tool that will facilitate our needs. With this in mind, which elements do we need to promote collaboration in a virtual design process? This thesis will include design processes, collaboration, creativity and virtual awareness, amongst others.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.
