Att skapa en snabb, sökdriven e-handelssajt : en studie med backend-lösningar i fokus

AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

Att förbättra lärbarheten : en användabarhetsstudie på webbaserade system

Syftet med rapporten är att belysa lärbarhetsaspekten som en del av användbarhet. Diskussionen grundar sig i ett större projektarbete om BG Faktura, en produkt från Bankgirocentralen. Bankgirocentralen gav i uppdrag att ta fram metoder, testanvändare och att samordna en användbarhetsanalys på BG Faktura. För att få fram användbarhetsproblemen genomfördes ett flertal utvärderingar; en heuristisk utvärdering, en kontextanalys och empiriska användartester. Då utvärderingsmetoderna resulterade i många användbarhetsproblem skapades en prototyp med modifieringar av BG Faktura enligt de rekommendationer och förslag som kommit fram i testerna.

Thecause of the poor modeling was unclear concepts.

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.

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..

Företagsbibliotek i förvandling : företagsbibliotekens tjänster i informationsåldern

A company library can only exist if it contributes to a positive result for the company. As endusers are beginning to perform searches on the Internet and have access to databases and electronic documents via their desktops it becomes important for company librarians to thoroughly think through what services should be offered to the users so that the library still contributes to the company s profit. The aim of this dissertation was to try to define the services that the company library offers its users having in mind the changes that have taken place concerning the availability of information. I also wanted to explore whether the librarians had the necessary competence to perform the services offered. Six information specialists were interviewed to give their view on the services their libraries offered.

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.
