Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

The ability of a dog to perform some kind of practical work, for example hunting or herding, depends among other things on its behavioural characteristics. In animal breeding it is not always easy though to select for behavioural traits. It may, for example, be difficult to identify traits that are not only heritable but also of importance for the dogs' ability to perform the practical work of interest. Moreover, it is often difficult to accomplish accurate measurements of behavioural traits. When selecting dogs for breeding, it is usually preferable to evaluate them using an objective and standardized bahavioural test, rather than results from field trials.

Aortic insufficiency is a very common valve problem in horses and most often affects older individuals, but nevertheless existent within younger ones. The root cause for aortic insufficiency can be varied, for example; endocarditis, ventricular septum defect or congenital valve disease but the most common are progressive valve degeneration or elite competition. Depending on the root cause, different changes can be observed on the aorta valves, but they do all have the same effect, the valves do not seal properly and blood leaks backwards. Many horses can, even with this deficiency, perform highly without any visible impacts and there is therefore no need to treat those subjects. Most often the symptoms arise at a later stage in life and they are, more often than none, put down for other reasons. In the occurrence of the clinical symptoms showing, treatment guideline is to inhibit these symptoms since the valve degeneration is presently irreversible.

This study investigates, through parental evaluations, communicativeand adaptive abilities within a group of children with various developmentaldisorders, after the parents had participated in AKKTIV (Augmentative andAlternative Communication ? Early Intervention) parental education. The studyalso investigates through case studies how parents experience the influence ofAKKTIV-intervention in their children?s development a few years aftercompletion. The parents estimated their children?s abilities using three differentquestionnaires; the Swedish Communicative Developmental Inventories(SECDI), Vineland Adaptive Behavior Scales-II (VABS-II) and parts of theform? Parents? perception of the interaction with their child?, before and afterthe intervention.

This essay focus on the European Union and its democracy both from a national perspec­tive and from an international perspective. Furthermore, the essay center on the con­cept of democratic deficit, this in order to study the European Union´s status regarding the democratic legitimacy. This study intends to nuance the problems that previous research and previous researchers have de­fined as democratic deficits in the European Union and ends up in conducting a textual anal­ysis of the latest European Union treaty, the Lisbon Treaty.The aim is that by using previous research on the democratic deficit in the European Union examine whether the Lisbon Treaty has enhanced the EU's position regarding democratic legitimacy. In other words, my study aims to identify what the deficit is and if it exists.The results show that the Lisbon Treaty has been trying to improve the democratic legitimacy and that some practical adjustments have been made, but it also show that there is much that still can be improved before citizens have full democratic rights..

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.

The purpose with this essay is to describe how the principal, social worker and the teacher work to prevent bullying at school. The following questions have been discussed:Does the school have an action plan for bullying, and if so, what does it say? Who has the practical responsibility for making sure that the plan is followed, and how does that responsibility work? How is the responsibility divided between the different professions? Are the children in any way active in the planning of the work against bullying? What does the children think about who has the main responsibility for stopping bullying?The method I have used in the essay is individual interviews with principals, welfare officers and teachers from two schools.My results show that the schools have different ways of handling bullying, and different forms of cooperation within the staff. One school have active students in the work against bullying in the form of classmate support (kamratstödjare). The social worker is used in different ways in the work against bullying.

The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.

Universal Design is a well established methodology with the fundamental purpose of designing products to be usable for as wide audience as possible, without the need of special adjustment to suit the individual. In this essay, Universal Design has had a clear influence in both the process and the result. The choice to use Universal Design as methodology in this usability evaluation, has essentiallv to do with the target audience.As a part of the design process of MyTobii C8 has Tobii Technology ask for a usability evaluation. MyTobii C8 is an 8" touch screen computer with a windows based operating system which will initiate the software MyTobii C-Series Control. MyTobii C-Series Control is the control panel for MyTobii C8, whose interfaces constitute the platform for various modificarion of the unit.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

The digitization in the Swedish health care sector is rapidly growing. This study investigates whether the digitalization in health care has led to higher quality and an increased value for patients. Interviews with staff in various health care professional categories were conducted to qualitatively study how the implementation of digitization is perceived in practice by those directly involved. Furthermore, an observation was made, where a doctor was followed duringa workday to study the different digitalization software tools that are being used. Previous studies and other relevant literature accompanied the study of digitalization in health care. Organizational theories were compared with the practical organization management at the studied health care organization, as well as their dependence on other authorities and companies.

Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

The purpose of this study has been to compare teachers' differing methods of teaching mathematics and their perspectives on the learning process in a municipal school to a Waldorf school. The study has examined which approach best promotes student engagement and learning in mathematics in the first three years of schooling. The study is based on four interviews. The informants? accounts are interpreted using theories from previous research.

Sexual dysfunctions concerning women with multiple sclerosis (MS) are common. Since the disease preferably affects young individuals when establishment of family occurs, the result of these problems have a great impact on the individual and her family. The purpose of this literature review is to throw light upon these problems and respond the questions if the nurse may be the right person to give sexual counselling and in which way this may be done. The theoretical framework was Antonovsky´s concept "sense of coherence". The result is presented in four themes: bodily aspects, social aspects, information/counselling, and practical implications for nurses.

Background: Almost every 20th child is borne premature in Sweden, before the parents are ready to care for a new family member. The parents need to cope with the stress and anxiety of having their newborn child in the neonatal ward and influenced by nursing care of neonatal staff grow their parental role.Purpose: The aim of this study was to illustrate experiences of parenthood within the care of premature at the neonatal ward.Method: A review where 18 articles between 2000 and 2005 were chosen and examined. The articles were analysed according to VIPS, which facilitates the practical use of the result.Result: The study reveals that parenthood is experienced as a time dependent process with three phases, primary, secondary and tertiary, where the parent?s needs and experiences changed character. The parents experienced that they developed from passive to active in the care of the premature child when the neonatal staff guided their participation, gave information/education and support.
