Webbaserade informationssystem blir allt vanligare och komplexiteten på system ökar. Tidigare har utvecklingen varit driven av tekniker och verktyg med avsaknad av metodstöd. Det finns metoder tillgängliga vilka specifikt är framtagna för utvecklingsmiljön, men användningen av dessa verkar vara låg. Arbetet syftar till att undersöka i vilken utsträckning som metoder för webbaserade informationssystem används och varför de inte används i högre grad. För att svara på denna frågeställning har en enkätundersökning genomförts mot systemutvecklare som arbetar med webbaserade informationssystem.

Context. Performance and resource usage is often an important factor for database driven services. Depending on the purpose of the application, choosing the wrong type of database may require unnecessary hardware upgrades or replacements. Objectives. This study investigates the differences in performance and resource usage between different SQL- and NoSQL-databases. The study is a comparison that focuses on how the databases perform in different applications.

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

The Smart Grids development is driven by forces concerning safe electrictransmission done in an energy efficient way. Vattenfall Eldistribution AB has a visionto transform their electricity network into Smart Grids. To invest in Smart Grids theyhave a need to show their customers what advantages they will get from thedevelopment. This led to the formulation of this dissertation project where the aim isto identify products and services related to Smart Grids that will increase thecustomer satisfaction for Vattenfall Eldistributions private customers.The project started with a mapping of existing products and services on the Swedishelectricity market. From the mapping several development possibilities for VattenfallEldistribution were identified.

To log on to social media has become an obvious part of people's everyday routine. Pictures, videos, opinions, and thoughts are posted and read by people's social networks worldwide. In doing so, the present study chose to examine whether what is posted on social media, as well as what the individuals are exposed to on social media can be related to their motivation and self-esteem. By letting 117 adolescents aged 16-19 answer a questionnaire regarding which social media they are active on, how often they are active there, and what they post on those social medias. By also letting them evaluate how they see themselves, if they compare themselves with others and how motivated they are to physical activity and healthy eating habits, we could see that to those who post pictures, and are exposed to images represent exercise / health on social media have higher self-esteem and driven more by internal motivation to engage physical activity than those who do not.

Målet med studien har varit att ta reda på hur man med hjälp av IT kan stödja enimplementering av IT-baserad planering inom transportbranschen, mer specifikt ruttplaneringsamt se vad som krävs för att reducera den stora mängd komplexitet som omger den. I fleraartiklar från Computer Sweden diskuteras det att man med hjälp av IT-stöd kan minskakostnaderna, öka inkomsterna och arbeta på ett mer klimatsmart sätt. För att få kunskap omområdet har Gayialis och Tatsiopoulos artikel Design of an IT-driven decision and supportsystem for vehicle routing and scheduling använts som kunskapskälla och som ett anpassatteoretiskt ramverk efter vår studie. Vidare har litteraturstudier utförts inom logistikområdet.För att bygga upp en empiri har en kvalitativ intervju genomförts samt en undersökning avbranschanpassade IT-lösningar. Resultatet av datainsamlingen blev en punktlista på komplexaparametrar som måste hanteras av den undersökta transportorganisationen för att uppnåeffektiviseringsvinster med hjälp av IT-baserad transportplanering.

Technical products are becoming more and more complex, this means that the drivers, mechanics and service personnel?s need for assistance such as the service literature is increasing. In this degree project the focus is on the technical manuals of Scania?s Workshop Manual. Today, the information in the Workshop Manual consists of collaboration between text and illustrations.

The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.

The vast majority of parents want their children to succeed and become successful in one way or the other. The very first is that the child will graduate from school. In today?s society which is characterized by career-driven parents, especially mothers, one wonders if somewhere along the way parents are prioritizing their own careers over their children?s school achievements. This might be true in some cases, but in others it could merely be that parents are expecting more from their children?s future.

"Race" is often used as a marker to exclude people from a society. What is interesting is not so much what terms that are used to describe people, but by what meaning they are associated with. For this thesis articles published in daily magazines have been the material used. An argument driven in the essay is that identity and oppression is not constituted from one subject position, but from several, such as class, sexuality and gender. The first question posed is how "race" is constituted through discourses throughout the subject positions class, sexuality and gender.

In this study I examine the debates, intentions and ideas concerning the physical and created schoolroom as they appeared in the journal Lärarnas Tidning - Svensk Skoltidning (Teachers Journal ? Swedish School journal) during the period 1962-1974. The built and created school building and its environment has been a relatively neglected topic in Swedish pedagogical research.When the Swedish comprehensive system transformed during the sixties, with new curricula and a common nine year school, many school professionals realised the need for a new and pedagogically adjusted schoolhouse.The early seventies marked a decline after a ten year period with an extensive building program affecting large parts of Sweden, and where schoolhouses had been an important part. The debate concerning the new Swedish school building was sometimes inspired and refreshing, but resistance and bitterness was also expressed. In part, this should be seen against the backdrop of the introduction of a new educational system, using new and sometimes untested pedagogical ideas, together with the fast transformation of the Swedish society.The research method is an exploratory textual analysis focused on five different issues: ideas concerning community centres and integration, participatory and democratic issues about the built environment, the school building as a pedagogical tool, aesthetic considerations, and the working environment.

Dementia may cause impairment of linguistic abilities, affecting both production and comprehension, which in turn affects communication (Mahendra & Hopper, 2012: Perkins, Whithworth & Lesser, 1998). The aim of the present study was to investigate and describe the communication strategies in everyday conversations between people with dementia and their interlocutors, and to describe the identified interaction phenomena based on a participatory perspective.The study was conducted at a home for people with dementia. Three people with known dementia and two health professionals participated in the study. Everyday interactions were filmed, and then transcribed and analyzed according conversation analytic principles. The transcribed data was also analyzed with ideas from positioning theory.The present study highlights the presence of trouble sources in communication between the person with dementia and carers and how these are handled by the participants in terms of strategies, competence and positioning.

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.

Denna studie behandlar teorin om disruption samt hur högskolan kan med hjälp av denna teori skapa nya utbildningar som är mera meningsfulla för studenterna. Fokus ligger på hur världen runt omkring högskolan förändras vilket gör att högskolan behöver förändras för att kunna erbjuda utbildningar som är relevanta för studenter i framtiden. För att klara av detta behövs en ny affärsmodell utvecklas som kan skräddarsy utbildningar till studenter efter deras unika behov. Orsaken till varför inte den traditionella högskolan kan erbjuda skräddarsydda utbildningar är för att affärsmodellen är standardiserad och ömsesidigt beroende. Även sättet att leverera kunskap på behöver förändras från traditionell undervisning till en datorbaserad undervisning.

Syftet för uppsatsen var att undersöka om klienter med tidigare narkotikaberoende upplever att de har möjlighet till inflytande inom vården som de tar del av. Syftet var även att ta reda på hur socialarbetare inom samma vårdprogram arbetar för att möjliggöra brukarinflytandet för klienterna. Vi utförde semistrukturerade intervjuer med fem klienter och två socialarbetare från samma behandlingshem. De teoretiska perspektiv som stod till grund för analysen av empirin var brukarinflytande och demokrati. Resultatet visar att klienterna upplevde stor delaktighet inom vårdprogrammet samt i kontakten med socialarbetarna på behandlingshemmet.
