The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.

The purpose of this study is to investigate the motives underlying the consumption of alcohol among college students and if the motives differ between genders.

The study group consists of students from a university in central Sweden. After an exclusion of five students a total of 81 students participated in the survey, of which 55 were female and 26 were male.

Sverige har länge haft en god kultur av öppenhet i den offentliga sektorn tack vareoffentlighetsprincipen. Men med allt större tekniska framsteg och ökade krav på datatillgängligheträcker den klassiska öppenheten inte längre till. Det finns redan mycket intressant offentlig data iSverige, men i de flesta fall är den antingen sparad i format som är svåra att avläsa digitalt eller fördyr att använda.I denna uppsats undersöks hur ett API kan utvecklas, användas och integreras med andra API:er föratt öppna upp ovan nämnda data på ett bättre sätt och göra den mer tillgänglig för potentiellaanvändare. Vidare undersöks också PSI-direktivets egentliga nytta och hur det tillsammans medoffentlighetsprincipen kan bidra till den nya öppenheten. Med koppling till denna uppsats har ävenen prototyp utvecklats för att ge exempel på hur man kan kombinera olika API:er för att visualiserageografisk data samt hur ett API kan byggas ovanpå visualiseringen för att göra denna data mertillgänglig..

The printer is a Ricoh AFC 6513 and it is a model that can handlevariable data. It was bought in the autumn of 2002. The teachers of the graphic education want to makeuse of the variable data function and procure a variable data software. The purpose of this project is toevaluate variable data software?s, so that the most suitable choice of software can be made for the graphiceducation.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

This essay examines how the conflict in Libya in 2011 was reported by the Swedish newspaper Dagens Nyheter and the American newspaper The New York Times. The purpose is to examine how the conflict is portrayed and what similarities and differences that exist between the two newspapers. We have used a quantitative content analysis and critical discourse analysis to get our results. In conclusion, both newspapers polarize the conflict to a large extent, resulting in a one-sided and biased account. However The New York Times is more objective and neutral in its portrayal of the conflict..

The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal. Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.

I dagens utvecklingssamhälle är det mer en regel än undantag att data lever längre än applikationen. Detta innebär att en organisations masterdata, grunddata, måste överleva förändringar i applikationslandskapet. Masterdata har stort värde i en organisations affärsprocesser varför det är av högsta betydelse att kontrollera dessa. Master Data Management är en applikationsoberoende process för hantering av masterdata vilken används inom många stora företag för att kontrollera kvalitén på masterdata. Syftet med studien var att få insikt i hur ett stort globalt företag arbetar med Master Data Management, för att på detta sätt kunna bidra med förståelse och erfarenhet vilket kan vara till nytta för andra aktörer i området..

In everyday life we perform motor behaviours that have no apparent instrumental function. Are these correlated to sensation seeking and do they differ depending on what situations we are in? University students in Örebro (N=108), participated in the study. The participants were asked to fill out a double questionnaire containing the sensation seeking scale and another one for measuring non-productive motor behaviours. The non-productive motor behaviours were not correlated to the sensation seeking scale.

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.
