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.

The aim of this study is to examine how one can understand the experiences that social workers within the social service's have of children who have committed sexual assault against other children, and the social workers? thoughts about the choice of actions and the family involvement in those actions. The study has a qualitative character. Information was obtained through interviews with social workers within two Swedish counties, and the analysis of the results was based on earlier research findings as well as theoretical aspects, such as systemic theory and salutogenesis.Regarding the actions taken for the target group, the social workers have, in many ways, a systemic perspective as they emphasize elements within the child as well as within the family. It is also shown that the collaboration with other authorities affects the choice of actions, and that it is important to involve the entire family in any interventions, so that the effect of those interventions may last over time.

Background:IT development has in recent decades been fast progressing. In Sweden many schools have begun to invest in IT and new technologies. What happens at the schools that are investing in IT equipment and modern technology?Purpose:The purpose of this study is to elucidate the conditions for and the success factors and barriers that principals and teachers will experience in IT. Principals' experiences are complemented and mirrored against the teachers.

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.

The purpose of this study is to investigate the reading methods that pedagogues, active in classes 1-3, use in the first stage of learning to read and how they consider their own choices of methods. In the theoretical background I sort out the basic differences between synthetic and analytic methods of acquiring the skills of reading. The analytic reading method means that the skills of reading starts with the complete text in order to later analyze the parts of the text. The synthetic method approach is based on a reading method where the parts are linked as a whole. The two methods are considered antipodes but can also be looked upon as complements in the current governing documents.

Previously when I have made proposals for privately owned gardens, I have found it difficult to find strong, extensive designs and to work with room and space. Since this is the field within which I am going to work in the future I feel that I need more experience, reference material and ideas on how I, in an early stage of the working process, can work with and consider room and space. The aim of this project has therefore been to procure experience, reference material and ideas for design of a garden in relation to space. To procure experience and reference material I have, during the fall of 2008, made two incredible study tours to France and to Japan. I have interviewed the landscaping architect Maria Arborgh and studied literature. I have also used a garden outside of Gothenburg in which I have been able to try out different thoughts and ideas regarding shape that have appeared during the course of my work. My conclusions about landscaping are that you should first find the different functions in the garden. The next step is to find an overall theme or shape, use a small number of materials, build a room with sealing, walls and portals with the help of vertical elements e.g.

My essay is on the subject of teachers work environment with focus on noise and communication. In the essay questions are raised on how a teacher can influence his or hers noisy work environment. A school is a large work place with many employees and is owned and administered by the county municipality which is an even bigger workplace. How big an acting space does a teacher have in such a large organization?My methods of research on these questions have been to conduct interviews and analyzing documentation from The Swedish Work Environment Authority.

The purpose of this essay was to examine and shed light on bullying as a groupprocess, a social phenomenon taking place in a school setting, to increase the understanding of the phenomenon. A theoretical overview of the litterature on bullying was made to investigate bullying and to give the reader a view of the researchfield. A total of 77 articles was studied. With the intention of studying bullying from a groupsychology perspective a metaanalysis was performed discussing groupphenomenon such as rolebehavior, responsibility, cohesiveness and norms in comparison to bullying episodes.Stemming from this analysis the question whether bullying can be view as a response to groupthink emerged. This question also constituted the secondary aim of this thesis.

Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.

    Abstract The aim of this paper is to highlight experiences gained by psychotherapists in their work with young adults.  Aspects looked at include: recurring themes, the process of diagnosing young adults, the therapeutic alliance, and the therapeutic techniques.  Six experienced psychodynamic therapists were interviewed, and a semi-structured interview method was used. The results show a high level of agreement between the therapists as to their experiences and conclusions of psychotherapy with young adults.Results presented in this paper suggest that there is a difference between psychodynamic therapy used with young adults, and the more traditional psychodynamic therapy.  The most important difference turned out to be the approach of the therapist toward the patient, where a more active and distinct approach by the therapist to the here-and-now situation was to be preferred. All six therapists came out strongly against the use of the DSM manual when diagnosing young adults. The importance of understanding young adults and their difficulties from a psychological development point of view was stressed, as well as the importance of taking the approach that the years of young adulthood bring their own issues and concerns. It is clear from these interviews that there is a strong need for the establishment of institutions or centres specifically tailored to meet the needs of young adults for psychotherapeutic treatment at an early stage and in an adequate way, in order to avoid unnecessary ?pathologising? of their specific problems.  .

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.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

ABSTRACT Infertility is a medical condition that affects approximately 16 % of Swedish couples in childbearing age and is a condition found in both men and women. When a couple has been trying to conceive for more than 12 months without success they need to see a health care provider. Infertility can be treated with medicine, insemination or assisted reproductive technology such as in-vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). The aim of this study was to validate a morphokinetic selection model, KIDScore? D3 Basic, against morphological selection model that is currently in use at the Fertility unit at University hospital in Orebro.

An increasing number of students leave the Swedish compulsory school without having a satisfactory grade in mathematics. Causes why students risk ending up with difficulties in the subject of mathematics are debated but one explanation might be that more and more students are diagnosed with dyscalculia. The purpose of this study is to investigate how educationalists identify and organize their teaching in order to help students with difficulties in mathematics to reach the schools requirement and long-term goals that are defined in advance. It is vital to detect learning difficulties at an early stage. Accordingly, it can be avoided that the student starts to develop a negative self-image due to repeated failures and in the same time provide relevant help.

Det är viktigt att vägarna håller så länge som möjligt. En faktor som har en påverkan i asfaltens långvarighet är bitumen. När bitumenet föråldras försämras dess egenskaper som ökar risken att skador uppstår på asfalten. Med hjälp av olika tillsatser kan bitumenets egenskaper förbättras. En av dessa egenskaper är bitumenåldring.
