Spam : den nya tidens onlinegissel

This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

Hjärtfrekvens och kortisolkoncentration hos valpar under olika typer av valptest :

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Läsa, fråga, förstå : Läsförståelsestrategier gestaltade i boksamtal.

Denna studie är utförd inom lärarutbildningen och kursen Språk och språkutveckling. Syftet med arbetet har varit att undersöka hur elever i år 1 agerar under boksamtal och vilket lärande som gestaltas i dessa samtal. Sex elever i år 1 har deltagit i en serie boksamtal som planerats och genomförts med inspiration av den sokratiska samtalsmodellen (Lindström, 2000). Studiens resultat har belysts med tre teoretiska perspektiv; ett didaktiskt perspektiv, ett receptionsteoretiskt perspektiv samt ett läsförståelseteoretiskt perspektiv. Tre kategorier av läsförståelsestrategier identifierades; att fråga, att göra inferenser och att läsa.

Kontextmedvetenhet som ett sätt att reducera Information Overload : Designriktlinjer för kontextmedvetna smartphone-applikationer

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

Andra Libanonkriget 2006 ? Finns det Ytterligare förklaringar till Israels misslyckande?

The response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.

The following questions were considered: i) Who is cultivating mountain holdings today? ii) Which is the most important reason to keep animals there? iii) What kind of subsidies are most common? iv) What kinds of animals and what breeds are the most common? v) For how long period of time are the animals kept at the mountain holdings every season? vi) How are the fundamental regulations in the animal welfare law being followed, and are there any problems/conflicts in keeping animals at the mountain holdings? vii) What meaning do the animals have for the farmers and what are the farmer?s thoughts about the future? A survey based on these issues was sent out to 107 mountain holdings farmers with animals on grazing land, where 59 % submitted a response. The results showed that knowledge on how to keep animals at the mountain holdings was overall good.

En läroplan utan stort tolkningsutrymme? : En undersökning av Lgr11 ur ett läsarorienterat perspektiv

This essays aim is to investigate the possibilities of subjective interpretation of Lgr11, the Swedish curriculum for elementary school. The assignment that the Swedish authority Skolverket got in 2009, was to create a curriculum that would grant that the students achievements would not be influenced by any subjective opinions and that all elementary schools in Sweden will give an equivalent education. In the Government bill this is a theme throughout the text and the Minister of Education has also claimed that this document will leave very limited space for subjective reading and interpretation. He says that Lgr11, in contrast to the previous curriculim Lpo94, will clarify what the purpose of the different subjects is and on what grounds the assessment of the students should be based.The method used is the literary theories of reader ? response as they are expressed by Literarycriticist Stanley Fish.

Tillgänglighet och verksamhet för dyslektiker på folkbibliotek i Södermanland

The aim of this thesis was to investigate the accessibility and activities for dyslectic adults in public libraries in the Swedish county of Södermanland. The questions that were to be answered were four; to what extent do the libraries provide book material and special computer software? To what extent do activities occur? Does the library staff have awareness and knowledge of dyslexia and of activities for dyslectics? What are the obstacles for good service for dyslectic library users? Two methods were used. As a first step, a questionnaire was sent to thirty public libraries. The questionnaire elicited a low level of response, but gave in spite of this an overview of the situation for dyslectics in the libraries of the county.

Beslutsfattande vid anbudsgivning hos svenska byggentreprenörer

This thesis examines the tendering process from the point of view of Swedish building contractors. The purpose with the study is to chart the decision process for the contractors during the tendering process. The study is designed as a survey study. This made it possible to reach a wide base of respondents, not letting such factors as geography being an issue. The survey itself was characterised by a very high response rate compared to other similar studies. The result from this study shows that former experience from similar projects, current workload and the clients economic condition are very important factors for both whether or not the contractor will bid for a project as well as the cost estimation and tendering price. Former experience from similar projects is also an important factor for the determination of the indirect costs.

Ta på era "hållbar utvecklingsglasögon"! : Ett idéhäfte som kan hjälpa pedagoger att arbeta mer med hållbar utveckling i förskolan

Natural and environmental issues are everyday parts in preschool but when educators shall consciously work with sustainable development they tend to stop at recycling and what is necessary to be done for achieving the Grön Flagg-certification. I have been observing various preschools and noticed that sustainable development is flawed, often because of the teachers lack of interest, knowledge and in some cases both. Out of this grew an idea of making a project that could help the teachers see how the work with the subject in a fun and educational way can become a part of the preschools everyday routine. I made a tutorial booklet with basic facts and activities relating to sustainable development and the three questions in my report were how much knowledge and interest the teachers initially have, if the tutorial booklet could help the teachers to produce new knowledge and interest for the topic and if it turned out to be easier for them to provide educational activities within the subject. There were three departments that participated in my survey and the methodology of collecting data was an anonymous survey with the teachers' own comments in response.
