Smart men illojal : Hur trådlösa nätverk gör oss till publika personer
Digital artefacts such as smartphones have become an intricate part of our daily lives both private and professionally. They have evolved from doing simple tasks to become a form of expression, as well as acting as a gateway to the digital world of connections. We rely on various technology such as Wi-Fi networks to connect with others. They in turn have become more available and today, many establishments offer free network to their customers. With these developments comes different kind of risks for the user.

Förbättringsarbete på monteringsbana
In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.
Uppleva eller leva upp till? : En studie om hur gymnasieelever upplever prestationskrav i idrott och hälsa.
AimThe purpose of the study was to investigate how upper secondary school students experience performance demands during their physical education and health classes (PE-classes). The questions were as following: Are there differing perceptions between the sexes whether students experience performance demands? In what situations do the students feel that the demands on their performance are high during PE-classes? Do the students experience of demands on performance differ whether the physical education and health teacher is male or female? Do students feel unfairly treated by the physical education and health teacher during PE-classes?MethodSeven upper secondary schools in Stockholm?s administrative district were randomly selected to participate in the survey. The principals were contacted for further information and to set a date for performing the survey. The project leaders were present during the days the surveys were taken by students in the social science and natural science programs.
I medborgarnas tjänst?:En studie om avregleringens effekter på ansvarsfördelningen mellan offentliga och privata aktörer inom tre samhällsviktiga serviceområden i samband med orkanen Gudrun
The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.
En osäker eller rätt(s)säker organisation? En hypotesprövande idealtypsanalys om gräsrotsbyråkraternas handlingsfrihet inom Arbetsmarknadsverket
Ever since Lipsky wrote about street-level bureaucrats in 1980 the main belief has been that certain characteristics of their jobs make it exceptionally difficult to severely reduce their discretion. However, discretion comes at a price and if public servants abuse their power the legitimacy of government is at risk and ultimately even the democracy.This thesis address this question by analysing the Swedish employment service which in the beginning of 2001 started a project called ?Af Sverige? trying to improve internal rule of law. By comparing two local and fairly equal jobcentres and how the street-level bureaucrats within use their discretion, I seek to find support for my hypotheses that organizing local jobcentres according to the principles of machine bureaucracy plays a significant part in reducing discretion.My findings show that a jobcentre characterised by strict rules, few units, good communications and a forthright manager who delegates formal power to the employees results in a stricter and more uniform application of regulations among the street-level bureaucrats. My conclusion is therefore unambiguous.

Science fiction i spelutveckling
Detta kandidatarbete undersöker science fiction, en av de större och vanligast använda genrerna inom medier såsom spel, film och litteratur, genom att studera dess undergrupper, de så kallade subgenrerna. Dessa är specialiserade versioner av genren i fråga och använder den inom vissa förutsatta ramar, exempelvis hur samhället ser ut eller vilken typ av teknologi det huvudsakliga fokuset kretsar runt. Genom att studera hur subgenrer är beskrivna i The Encyclopedia of Science Fiction kan man avgöra att de består av sex punkter: plats, tidsperiod, karaktärer, teknologi, narrativ och visuell estetik. Dessa punkter har använts som ramverk för att utveckla en ny subgenre; Mystech, där scenarier utspelar sig i vad som kan ses som en typisk fantasyvärld med magi och monster, men där dessa egentligen bara är teknologi majoriteten av de påverkade inte förstår sig på. För att demonstrera Mystech har två olika miljöer utvecklats, både i bild och skriven form.
?Webbaserad visning av positioner på karta
Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution.This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers.This master thesis can be split into two separate parts, the theoretic- and the practical part.The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements.The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability.
Valet av grafiskt dokumentgränssnitt
Grafiska dokumentgränssnitt används av de flesta datoranvändare. Det finns i
huvudsak tre typer av dokumentgränssnitt; MDI (multiple document interface),
SDI (single document interface) och TDI (tabbed document interface). I ena
halvan av arbetet har dessa tre analyserats utifrån en rad faktorer med målet
att se om någon modells fördelar väger över de andras och om man kan skapa
några riktlinjer för när det är bäst att applicera respektive modell när man
utvecklar en ny programvara. Analysen är baserad på litteratur samt kvalitativ
enkätundersökning och programtest. Andra delen av arbetet har ägnats åt testa
om det går att programmera så att slutanvändaren kan välja den modell han eller
hon föredrar.
3D-visualisering till Eve
Vi har under tio veckor producerat en del av Peter Martinssons film Eve. Vi har
stått bakom en stor del av den tekniska biten. Vi har inte deltagit något i
idéarbetet och idén bakom filmen, däremot har vi påverkat det visuella
resultatet genom att göra stora delar av bakgrundsmaterialet. På så sätt har
våra idéer och vår konst fått en stor del i filmen.
Genom detta arbete har vi velat utveckla våra kunskaper främst i programmet
AliasWavefront Maya, men även rent estetiskt. Målet med arbetet var inte att
bli klara med filmen, utan att lära oss av produktionsprocessen.
Vi har varit tvungna att anpassa oss i vårt arbete till det speciella utseendet
som filmen har.
Förutsättningar för intern marknadsföring inom grundskolan 2010 : 1 + 1 = 3 Nya insikter om förhållandet mellan tal, lärare och ledning
I och med friskolereformen i början på 1990-talet har förutsättningarna för skolor förändrats och konkurrensen hårdnat. Marknadsföring av skolor har blivit allt vanligare och vilket anseende skolan har är avgörande. Tidigare forskning har visat att nöjda anställda leder till att kunder blir tillfredställda och lojala, de som tar hand om sina anställda och agerar på deras idéer visar ett bättre resultat. Därför kan intern marknadsföring ses som ett verktyg för att hantera denna konkurrens.Syftet med denna uppsats är att utifrån ledningens perspektiv få förståelse för och beskriva vilka faktorer inom skolbranschen som påverkar den interna kommunikationen och vilka förutsättningar dessa faktorer ger för intern marknadsföring. Studien har intagit ett Grounded Theory-inspirerat tillvägagångsätt och tillämpar intervjuer för att svara på syftet.
Olikheter på arbetsplatsen. En studie om prioriteringar och marginaliseringar i svenska organisationers mångfaldsarbeten
Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.
Studenters mobilanvändning under föreläsningar : En studie om hur studenters koncentrationsförmåga påverkas av mobilanvändning under föreläsningar
In Sweden there is a long ongoing discussion about computer and cellphone usage during lectures in school. The discussion has mainly covered elementary school up to college students, but this topic is at least as relevant for university students. Today cellphones are so advanced; you can do everything with one that you previously only could do with a computer, the difference is that everyone is carrying one with them all the time. This study shows how concentration during lectures is affected by the cellphone accessibility and usage. With this study we want to find out how university students perceive cellphone usage affects their own concentration during lectures.
Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874
The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.
