Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

This essay examines the relationships between the different elements in Lisa Jonasson?s collage Existentiell Progg #6 and her very detailed technique. The essay has as its aims to understand and analyze both the details and the wholeness of the artwork and to try to put the collage in an art historical context. The thesis finds that Existentiell Progg #6 has a connection to the imagery of Africa and other collage artist such as Hannah Höch and Nancy Spero, which also gives the paper a perspective of feminism in the arts. The paper continues to create an understanding for the collage work by putting it in to Theodor Adorno?s theories about nature, the human being and the animal kingdom.

This report investigates what attitude private forest owners in the County of Stockholm, Sweden have towards biodiversity landconservation. Private landowners were asked to answer a questionnaire containing questions about there property and there attitude towards biodiversity. The results show that private landowners attitude towards biodiversity is affected by, amongst other things, the size of their property; a larger property have a more negative owner than a smaller property. A landowner that lives on his property has a more negative attitude towards biodiversity than a landowner that?s not living on his property.

Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..

Ibland kan det förkomma problem mellan utvecklare och kund/användare då de tar fram kraven till ett nytt system. En anledning till detta kan vara att utvecklingsgruppen och användargruppen inte har samma kunskaper och erfarenheter och talar då inte "samma språk". En lösning till detta problem kan vara att ta hjälp av en mockup. En mockup är en fysisk och/eller interaktiv modell av ett gränssnitt. I detta arbete har vi, med hjälp av intervjuer och observationer, undersökt om detta hjälpmedel underlättar kommunikationen i verkligheten..

I detta arbete framlägger vi ett designförslag på hur ett diskussionsverktyg som stödjer ljud- och bildkommunikation kan se ut. Ett förslag som förbättrar och förenklar den distanskommunikation som idag sker med hjälp av mobiltelefoner, videokonferenssystem samt webbkameror anslutna till persondatorer. Den design vi föreslår möjliggör för mobila användare att visuellt föra flerpartssamtal med hjälp av PDA:er. Vårt designförslag har fått arbetsnamnet CU2 (see you too) och är tänkt att fungera i tredje och/eller fjärde generationens mobila nät. Vi har valt att genomföra vårt magisterarbete på företaget A Brand New World i Kista, Stockholm. Företaget utvecklar och säljer system inom mobilt Internet..

Denna uppsats syftar till att undersöka om EU:s bistånd till Afrika tar hänsyn till om de afrikanska länderna har välutvecklade institutioner eller ej. Mycket forskning tyder på att givare av bistånd bör fokusera sitt bistånd till stater som har relativt hög institutionaliseringsgrad för att pengarna ska generera en positiv effekt. Jag undersöker detta genom att använda mig av en kvantitativ metod och regressionsanalyser för att få statistiskt material att tolka. Mina resultat tyder på att EU inte verkar utforma sitt bistånd genom att studera mottagarländernas institutionaliseringsgrad. Detta kan ses som en, av många, förklaringar till varför den afrikanska kontintenten inte uppvisar önskade resultat när det gäller fattigdomsbekämpning och demokratisk utveckling. .

The aim of the essay was to describe what some young Swedish and Spanish people had to say about alcohol cultures. Some of the questions asked were: How are the alcohol cultures in Sweden and Spain described? What are the differences, and where do they come from? What would an ideal alcohol culture look like? The investigation also had a comparing angle, as I was interested in what the people valued in their own culture and in the others´. The result was that there hardly exist a perfect alcohol culture, but that the stricter Sweden as well as the liberal Spain both have positive and negative aspects. Differences in politics and culture seem to create variations in a society´s drinking customs.

Biologisk mångfald i urban miljö har visats sig ha stor betydelse för människansrekreation och fysiska och psykiska hälsa. Samtidigt förbättras stadens hälsa genom debullerdämpande, luftrenande och klimatförbättrande egenskaper som vegetationen har.Syftet med denna undersökning är att utföra en temporal och rumslig analysmed avseende på antal och utbredning av rödlistade kärlväxter i Göteborgs innerstad under1900-talet. Utgångsmaterialet är Göteborgs artdataarkiv, ADA, en databas framtagen avGöteborgs miljöförvaltning som innehåller observationer av rödlistade och andra skyddsvärdaväxt- och djurarter. Då databasen är en sammanställning av olika inventeringar över lång tidär skillnaderna från ett material baserat på en systematisk inventering stora. Vagalokalangivelser och okänd observationsfrekvensen i ett område är faktorer som påverkarsäkerheten i materialet men det kompenseras genom ett stort antal observationer undermycket lång tid.Den temporala analysen av antalet rödlistade kärlväxter i Göteborgs innerstadvisar på en tydlig nedgång i rapporterade arter.

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Child sex tourism is a growing problem in todays globalized world.This paper is conserned with the problems of those who isn't sexually drawn to children when they are in their own community but who, on their travels, sexually abuse them.The aim of the study is to analyze what makes people commiting sex crime abroad, and breake those laws which, usually, are in line with the persons own values and normsystems.What impact has travelling and tourism on the behaviour of the individual? And which social factors makes people into sudden offenders? By comparing the litterature on child sex turismwith theories in sociology and criminology you could se some factors of and structures in society contributing to the issue..

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..
