Principles that guide how a classification system should be structured have existed for more than a century. Traditional classification principles can be of great value for the design of classification schemes directories on the web. However, there are differences between the library context in which these principles originated, and the web. This thesis aims at investigating how changes in the context of classification affect the application of traditional principles of classification on the web. Another purpose is to see what implications this has for the design of classification schemes on the web.

Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.

I föreliggande studie har unga flickors attityder till ätande över tid studeras, samt sambandet mellan föräldrars attityder till mat och ätande och deras döttrars attityder. Detta gjordes genom frågeformulären Children´s Eating Attitudes Test (ChEAT) och Eating Attitudes Test (EAT), från IDA-projektet (Identification of Dieting in Adolescent girls) som delades ut i 40 olika skolor i Uppsala län år 1995 samt 2000. Resultatet visade att det var elva procent av 14åringarna som låg i riskzonen (riskbeteende = 16-72 p) för att utveckla ett stört ätbeteende, medan det inte var någon utav nioåringarna som låg i riskzonen (M 9år = 1,88 M 14 år = 4,35p=.001). Inget signifikant samband mellan varken mammans och flickornas ätbeteende eller pappans och flickornas ätbeteende kunde ses. För att problem med ätstörningar hos ungaflickor ska minska tycker författarna att det är viktigt att föräldrar informeras om hur tidigt deras barn blir medvetna om kroppsideal samt matfrågor.

The aims of the study were to investigate the prevalence and antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of antibiotic resistance development. The study was conducted in the Can Tho province in Vietnam during six weeks in October to November 2008. Ninety-six samples from raw chickens were collected from twelve market places and analysed for the presence of Campylobacter. A total of 96 cloacal swabs from 20 farms were obtained and analysed for the presence of Campylobacter. Farmers were asked to answer eight questions concerning the housing of the chickens, modes of handling sick animals as well as use and knowledge of antibiotics and resistance development to antibiotics.

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 is based on the following questions: What are the motives underlying alcohol consumption among students? Do these motives differ between men and women? Is there any connection between the motives for alcohol consumption and consumption? The study is a quantitative, empirical comparison study and the data presented is mainly descriptive. 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.

Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.

The motivation for this thesis lies in the knowledge that there is a crucial information need amongst LGBTQ-persons wanting to read fiction related to LGBTQ in order to strengthen their own identity. This particular information need regarding identification has been said to be more central within LGBTQ-communities than within other user groups, largely because they represent a marginalized group in society. Critical feminists, such as Hope A. Olson, have proved that knowledge organization based on systems of subject representation in fact may lead to further marginalization and exclusion of already marginalized groups. Therefore, the aim of this thesis is to compare subject representation and social tagging as methods of organizing LGBTQ-fiction.

Ever since the nation-state has existed identity has been a big deal, it is told that identity is a tool needed to be able to receive consensus from the people concerned on a certain matter. As the European Union is continuously shaped and reshaped due to changing geographical borders, as a consequence of new member-states the aim to integrate the Union equally across its surface has not been an easy task to solve. A lack of trust from the inhabitants in the European Union is a fact, and therefore the main duty of the Union has become to rebuild the trust from beginning to end, creating a Union which easily can be identified with. Since the process of national identity relies upon an excluding-including process and the use of the Other, the identification process on an European level has indeed had fierce effects on the inhabitants within and outside the Union.One of many things that this essay aims at showing is how mythmaking has become a way used by the elite in the Union to integrate a European identity, the myths refer back to a Golden Age when Europe was prosperous and in bloom. Among other tools used to integrate and create a European identity we find such as; unity in diversity, a cultural inheritance based on common denominators such as Christianity and Latin traditions, symbols and a European citizenship.

The aim of the essay is to explore how so called ?safe spaces? are built, and the part that creativity can play in this construction. The essay also explores the duality of idea-based social work that at the same time strives to support vulnerable groups and strives to make social and political changes. The essay has its empirical base in the RFSL Ungdom project ?Tusen bilder, tusen ord? (A thousand pictures, a thousand words).

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

Syftet med den här rapporten är att beskriva ett antal olika tillvägagångssätt man kan använda sig av då man har behov av att dela in ett lokalt nätverk i olika segment och med det även kunna reglera trafikflödet mellan segmenten. De lösningar som presenteras i arbetet är inriktade mot mikro- och småföretag.Anledningen till att vi har valt att arbeta med det här området är att vi anser att det är viktigt för organisationer att har en strukturerad och segmenterad design på sitt interna datornätverk.Vi har arbetat genom att i förväg samla in information om olika tekniker som kan tänkas lösa vårt problem, och därefter testat olika scenarion med dessa tekniker. Data har samlats in efter varje genomfört scenario och sammanställts i statistisk form för att kunna avgöra vilken metod som var att föredra.Vi har testat lösningar där man segmenterar nätverket i en lager 2-switch medan man möjliggör och förhindrar trafikflöde mellan segmenten i en router. Även lösningar där man använder en lager 3-switch har testats. På så sätt kan routningen ske direkt i switchen och det blir betydligt mindre belastning i routern.

Bakgrund: Riksbanken har haft sedelmonopol sedan 1897, vilket har inneburit att de sedan dess har haft ensamrätt att ge ut pengar. Den teknologiska utvecklingen och den ökade användningen av internet har lett till att virtuella samfund har utvecklats och i vissa fall har dessa samhällen skapat sin egen valuta. Bitcoin är världens första helt decentraliserade valuta och baserades i början av sin existens på teknisk nyfikenhet för en handfull hobbyister. Under de senaste åren har efterfrågan på bitcoins ökat vilket i sin tur har lett till att kursen stigit explosivartat.Syfte: Syftet med uppsatsen är att kartlägga och analysera de transaktionskostnader som kan uppstå när Bitcoin används som betalningsmedel, samt jämföra dessa kostnader med de transaktionskostnader som är förenade med användandet av traditionella betalningsmedel.Genomförande: Studien har genomförts genom en blandning av ett kvalitativt och ett kvantitativt tillvägagångssätt samt genom en bearbetning av transaktionskostnadsteorin inom ramen för ny institutionell teori. Empirin består av tre delar där studien inleds med en litteraturstudie för att läsaren ska få en inblick i vad Bitcoin är och hur valutan fungerar.

Företag inom alla branscher arbetar aktivt med att minska sina kostnader genom ökad effektivitet i interna processer, så är även fallet inom daglivarubranschen. Ett sökande efter ny teknik och nya sätt att utveckla branschen står alltid på dagordningen. Radio Frequency Identification (RFID) är nästa generations identifieringsteknik för dagligvaruhandeln, det är därför viktigt att tekniken börjar implementeras och användas. Svenska Retursystem är ett företag som tillhandahåller returlådor till den Svenska livsmedelsbranschens aktörer. För att effektivisera användandet av lådorna så har de givit uppdrag om en undersökning om vilka effekter införandet av RFID i deras returlådor skulle ha på användandet.

The concept of security is a contested one. The United Nations definition in UNDPs Development report of 1994 is the most authoritive and commonly cited. The civil war in Sudan has led to 2 million deaths and over 5.5 million refugees. In a resolution from 2005, the UN decided that the war in Sudan was a threat to international security and peace. The 10th of January UN decided that a peace commission ought to be send with 10 000 military and civil men including 700 policemen.The main purpose of this thesis is to improve our knowledge of those factors which can cause an increased risk of conflict within a state, and how that can affect the social conditions for individuals.
