IT-investeringar har ofta till syfte att stödja verksamheten och att möjliggöra för företaget att producera och förse sina kunder med de tjänster och service som man har för avsikt att leverera. Att göra en IT-investering innefattar inte bara kostnader, utan en omfattande IT-investering innebär även stora förändringar i verksamheten. Därför bör det vara av intresse för företag att identifiera vilka effekter IT-investeringen medför. Sådana effekter kan vara mätbara, men det finns även effekter som är svårare att mäta, vilket kan innebära svårigheter när ett företag vill räkna på nyttan av investeringen. Tidigare studier har visat svårigheter när det gäller att göra lönsamhetsberäkningar av en IT-investering.

As a teacher in baking and patisserie courses there can be difficulties in following the curriculum for Patisserie 1. If this leads to an education that is not the same for all the schools in the country, it creates a problem that has to be solved. The results of this investigation show that teachers generally do not follow the curriculum but instead chooses their own solutions. Some conclusions that have come forth are that the National Agency for Education needs to make the curriculum clearer and give tangible examples of products, that can either be classified as easy or complicated, in the field of baking and pastry courses. I have chosen the standardized interview method.

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

Online dating and ?People nearby applications? (PNA) has become more popular in today?s society. With PNA you can easily find people who are nearby you that you can socialize with and maybe even meet. In this paper we study the mobile application Badoo and explore how it is used for dating in clubs in Stockholm through observations that we participated in. We also had a group interview with five Badoo users about their usage of the application.

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

The purpose of this thesis project was to study how different companies are working with LastTime Buy and through that study propose improved ways of working with this for Scania CVAB. The project aimed at studying the work processes from three different perspectives:decision models, quality aspects and liability aspects between companies.To study this, qualitative interviews with one or several representatives from differentcompanies that are affected by or involved in Last Time Buy were used. Representatives wereselected partly from Original Equipment Manufacturers, suppliers, component manufacturersand companies offering third part solutions for Last Time Buy. The companies also reflecteddifferent industries. The interviews aimed to create an understanding for the methods used atthe different companies but also the ways of thinking and the knowledge behind the choice ofthese working methods.The analysis shows that the Original Equipment Manufacturers used very similar decisionmodels for Last Time Buy, but that external factors or the company strategy made them reachdifferent results.

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Logistik har på senare tid blivit en allt viktigare del inom dagens samhälle i och med ökad globalisering. En verksamhet som effektivt arbetar med att förbättra sin logistik kan ofta erhålla stora konkurrensfördelar och om möjligt utöka sina marknadsandelar. Logistik medför dock ett antal kostnadspunkter, varav en utav de största är transporter. Av denna anledning är det av stor vikt att företag erkänner hantering av transporter som en central del utav den dagliga verksamheten.Syftet med detta examensarbete är att på Sulzer Pump Solutions Vadstena AB utvärdera samt studera verksamhetens transporthantering med fokus på inboundtransporter.I samband med ett ägarbyte har verksamheten genomgått stora organisationsförändringar där transporthantering har kommit att bli ett icke prioriterat område. Företagets transportkostnader är idag omfattande och det finns en tydlig önskan om att ta kontroll över transporthanteringen.

The aim of my study is to get an idea of how some teachers use homework, what they consider a good homework is, and what considerations they take to the students' home circumstances. I have made a qualitative interview study with four middle school teachers. The results of my study show that teachers can flip the classroom and use so-called preparatory tasks. The time saving aspect is a strong reason they choose that model. That students are able to practice their own responsibility and perform meaningful homework seems to also be in focus, but the biggest reason they use flipped classrooms seems to be because it is a more equivalent homework then traditional homework, and that students and their guardians also appreciate the flipped classroom model as they become more involved in their children's schoolwork..
