Alternativa metoder för att kontrollera ett användargränsnitt i en browser för teknisk dokumentation
When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.
IT-relaterade hot - professionella IT-tjänstemäns farhågor och möjligheter
The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security. When all the material was gathered we saw that we had strayed away from our subject and that our focus was on IT-threats and IT-professionals apprehensions and possibilities on the subject. The purpose of this thesis was there after to find and identify threats and counter measures in publications and later discuss these with IT-professionals. We found and identified several threats that the professionals encountered in their work. These threats ranged from techniques used by hackers to threats that can arise when the users on the network are poorly educated.
Ytterväggar : En jämförelse och livscykelskostnadsanalys
This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment.

Att sticka ett oroligt barn - sjuksköterskans möjligheter att lindra / To prick children : Nurses' possibilities to relieve distress
Background: Children frequently exhibit high levels of distress while undergoing routine blood sampling or injections. If the child is not treated with appropriate care, the feelings of distress may increase over time and result in needle-phobia. Objective: The purpose of this study was to describe nurses´ possibilities to relieve distress in children undergoing needle sticks. Method: A systematic literature review was conducted through database search and screening of reference lists. Ten research articles with a quantitative approach were included, coded for quality and then analyzed.
Marktillstånd och borbrist på åkermark planterad med gran i Västerbottens län :
This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that
1) Boron deficiency is present at several of the investigated objects.
2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime.
To be able to confirm or reject the hypotheses a number of tests were performed.
Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken
This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.
Värdering av varumärkesstarka företag i samband med uppköp: - en empirisk studie av fem svenska företagsförvärv
The aim of this thesis is to investigate how a valuation of a company preceding an acquisition can be affected by the fact that a strong brand is attached to the target company. Techniques to value a company and theories of brands are well developed, but the link between them is partially missing even though the needs to value brands have increased. A case study of five Swedish acquisitions is conducted to identify possible complicating and simplifying factors and how these are handled in the context of a valuation of an acquired company with a strong brand. Important findings are that a decreased volatility of future earnings can lead to more accurate prognoses and valuations due to the existence of a strong brand. A strong brand can, on the other hand, also make the valuation of the target company more difficult due to the fact that it is a subjective asset which increases the overall risk of the company.
Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Folkhemmets reklam : En jämförelse mellan reklamannonser då och nu
The first ad was published in Sweden 1645. Advertising itself is not a new phenomenon, it's just the conditions that has been changed. Today, advertising is a matter of course in our daily lives, every day we are exposed to thousands of messages that wants to persuade and convince us to consume. In this paper, we have looked into the semiotic and rhetorical tricks that are used for this particular persuasion, and we have investigated whether they have changed in the last 60 years or if the same tricks are still being used today. Our two hypotheses is: A) the rhetorical and semiotic basis of an ad looks the same today as 60 years ago.

Konvertering av CRM-system från ASP till ASP.NET
S2 CRM is a Customer Relations Management system built in classic ASP that runs on a web server servicing customers with varying needs. The purpose of this thesis work is to convert parts of the system to the web development environment ASP.NET. The purpose is also to gain knowledge of the framework itself. The ASP.NET environment is compared with another framework, JBoss Seam, in order to understand the differences and to evaluate the possibility of using another framework than ASP.NET, when building the new system. The outcome of this comparison is that although JBoss Seam is just as good, and in some aspects better than ASP.NET, the use of ASP.NET simplifies the continuation of development on the S2 CRM product.
Kunskapskompetens ? en samverkan mellan praktisk levd kunskapsgrund och vägledande teoretisk kunskap : Om kuratorer i hälso- och sjukvårdens uppfattning av deras praktiska- och teoretiska kunskapsanvändning i arbetsprocessen
In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.
Textil och glas ? ett universum
This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.
?Jättebra, fortsätt så!? : Responsens betydelse för motivationen i ämnet idrott och hälsa
This thesis explore women?s needs when reentering society after having served a sentence at the female prison Färingsö, outside Stockholm and whether those needs are being met in the reentry strategies that are being provided. Parallel to this the thesis also examines if there, based on nonconformity and gender theories, is a socially constructed representation of women maintained in the rehabilitation work.The method of this thesis applied semi-structured interviews and used snowball sampling to expand the network of informants to obtain the data necessary. Totally five interviews were carried out. Previous research has shown that women in prison have much more complex problems than men and that there is a need for reentry strategies that take gender in account.The results showed that in terms of being able to reenter back in society, women needed help to structure a previously chaotic life.
Temperaturens, kadaverålderns och radiopulssekvensens betydelse för bildkvaliteten vid magnetresonanstomografi av tarsus hos häst
Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
