Målet med detta projekt har varit att, till en ny digital handelsplats, ge ett förslag till en implementation av MongoDB, med tillhörande REST-API, för hantering av användar- och annonsdata. Förslaget ska innebära en prestandaeffektiv och säker databas med möjlighet till framtida skalning, tillsammans med ett API för klientkommunikation med hantering av relevanta förfrågningar mot databasen. Prestandan av databasen handlar främst om att i förslaget ange vilka olika former av indexering som bör implementeras, tillsammans med ett förslag till relationsmodell, och vad detta ger för positiva och negativa effekter på systemet. Denna prestanda bör även återspeglas till största möjliga mån i API:et genom att utnyttja den indexering som väljs på bästa sätt. Säkerhet och skalning diskuteras under arbetet för att ge ett förslag på hur detta bäst hanteras för minimera riskerna för dataförlust, samt minimera nedtiden av databasen vid en eventuell framtida skalning.

The Swedish government published their current proposition concerning cultural politics,Tid för kultur in 2009. Due to this proposition, culture is considered a basic human right we all deserve to be provided with. It contained goals and guidelines for how to enable culture to all citizens, to integrate and enrich the state, the county councils? and municipalities? work with diversity and multi culture in their culture-based institutes. However, there seems to be a lack of strategies in the issue of how to provide our nondependent elderly, suffering age related handicaps and diseases, with this proclaimed necessity.In recent years, there has been a lot of research proving the link between human wellbeing and a stimulating environment.

Previous research indicates that the academic journal in many cases is the most valuable and important source of information in scientific work. The aim of this study is to investigate students usage of academic journals in comparison to their usage of other document types, as illustrated by the citations given in LIS students master theses 1999-2001. By comparing the students use of LIS journals with the use of LIS journals by international scholars we also wish to examine whether students and scholars use the same journals in their work. The international scholars are represented by references given in LIS journals 1999-2001, recorded by the citation index Journal Citation Reports. Questions: 1.

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 with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.

Det är av intresse för aktörer på den finansiella marknaden att prognostisera aktiemarknadens reaktion på en ändring av reporäntan. Flera arbeten har de senaste årtiondena försökt påvisa ett samband främst på den amerikanska marknaden. Denna uppsats försöker sig i stället på att finna en korrelation mellan annonsering av reporänta såväl som förväntningar på reporänta och en onormal avkastning på den svenska aktiemarknaden. I arbetet används en event study på Affärsvärldens index under perioden 1997 till 2007. Perioden är vald så att det initiala trovärdighetsproblem för riksbankens inflationsmål som förelåg före 1997 inte ska påverka resultatet.

Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.

AbstractThe genetic diversity in cultural plants is considered to be threatened due to global climate change and antropogenic influence. Unknowing of future conditions for cultivation, gene banks all over the world are now trying to build up costly safety nets of species and varieties that may become highly valuable owing to their specific traits and genetic heredity. Hence, in 2002 there was a national inventory, aimed at the Swedish public, asking for seeds believed to be lost. Among the resulting collected seeds were some accessions of garden bean, Phaseolus vulgaris. The objective of this particular study was to assemble a collection of unique varieties and discard possible duplicates.

Since the 1970`s the Non Governmental Organisations, NGO:s, have taken an increasing responsibility in the development cooperation work. Apart from an increase in resources delivered through the NGO:s it is also obvious in various official documents that the idea of NGO:s in regards to; reaching and involving poor people in the work and as capable of delivering aid resources to a low cost, is very widely spread and commonly accepted among political decision makers and aid agencies. In addition it?s very seldom that those positive statements about the NGO:s abilities, are backed by any kind of scientific study. This study argues that the ascribed abilities are more the rhetoric of a political idea than an empirical reality.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

En chef använder olika färdigheter i sin vardag t ex kommunikation,relationsskapande och beslutsfattande. Likväl som chefen agerar med olikaledarstilar utifrån kontexten och medarbetarna. Kvaliteten på chefensfärdigheter och agerande kan bedömas i en medarbetarenkät därmedarbetaren även bedömer sitt och gruppens välbefinnande. Enmedarbetarenkät ska vara ett stöd för chefen att utveckla sitt ledarskap ochsin verksamhet. Denna uppsats analyserar de tio bästa och de tio sämstaenheterna från en medarbetarenkät i ett landsting.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

Today, Sweden is to be regarded as a country formed by the influences and effects of immigration. The government is considering integration as a process aimed to influent all forms of welfare politics and as a project working both at an individual and at a social level. The aims of integration policies are to guarantee equal rights and opportunities, to form a public community characterized by diversity, and to mobilize all citizens to participate in and to be jointly responsible for a social development characterized by mutual respect and tolerance. During the Swedish election campaign of 2002, integration policies became one of the most reported and discussed political questions in the media. The aim of this essay is to study and analyze discursive statements on integration policies made by politicians during this election campaign.

AbstractTitle: Communicating diversity ? A study about communication and involvement in The National Council of Swedish Youth Organizations.Number of pages: 58Author: Frida SamuelssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Autumn 2006University: Division of Media and Communication, Department of Information Science,Uppsala UniversityPurpose/Aim: The general purpose of this essay is to analyse how the member organizations of LSU ? The National Council of Swedish Youth Organizations, see the communication,activities and their influence over the organization. I aim to do an analysis of the target group to find out if the lack of involvement in LSU is caused by communication problems.Material/Method: The method of this essay is quantitative and is based upon a web-survey.The chairmen of the member organizations have been asked to answer a survey about the communication in LSU. To get an idea of how widespread different opinions about LSU are the empirical data has been made into graphs to show the frequencies and also cross tabulations to find out if there are any correlations between the variables.Main result: This study has shown that the problem with involvement in LSU is only partly a communication problem. One important result is that many member organizations feel that LSU doesn?t listen to their opinions and they express a wish to have more influence over the organization.
