Undersökning av ögats brytningsförmåga i ett svenskt hästmaterial :
Skiascopy, also called retinoscopy, is a method for determining the refractive power of
the eye. There are only a few, old studies made on equine refraction. The aim of this
study was to investigate the refractive power in a population of Swedish horses.
The study consists of a review of relevant studies done on animals and an experimental
part where the refractive power of 93 horses of different age, breed and usage was
examined. A pilot study of 12 horses was performed regarding the importance of
cycloplegia when doing skiascopy on horses.
The results of the pilot study show no significant difference in the skiascopy results
between the group before and after cycloplegia were induced. Consequently, there is no
need of inducing cycloplegia before doing skiascopy in adult horses.
The study shows that horses usually were emmetropic (normally sighted) with minor
deviations toward myopia or hyperopia.

Kunskap, ordning och krav : Liberalism och konservatism i Folkpartiets skolpolitik
This paper examines the ideological content of the compulsory school policy of the Swedish Liberal Party. The aim of the study is to investigate whether the Liberal Party does really represent a liberal policy for the compulsory school, or if it is more accurately described as conservative. The analysis is carried through by two separate critical examinations of the Liberal Party motion on school politics to the parliament and the Conservative Party motion on school politics to the parliament respectively. A comparison is then made between the ideological contents of the two documents. The specific party policies are linked to universal definitions of liberalism and conservatism with the help of an analytical tool consistent of a series of educational philosophies.

Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011
Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).
Affärsmodeller och Strategier i Apples Appstore
Apple has since their launch of the Iphone series created a billion dollar business with the market place Appstore. Third-party apps have disrupted the mobile industry, attracted a high number of developers and set the standard for the industry. Despite success, this market has yet not been the topic of any academic study, a fact that makes this thesis important. Under the assumption that apps can be regarded as a service, traditional service marketing theories have been applied with the research goal to map existing business models, evaluate revenue potential and understand best practices of marketing techniques. A series of qualitative interviews with representatives from the difference business models, backed by secondary data describing the domain shows how the Appstore has evolved over time and which marketing practices that appear successful.

Responsive web design : En studie i hur designkonceptet påverkar användbarheten hos en webbplats
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.
Utsläpp av växthusgaser under islossning i små boreala sjöar
Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.
Mångkulturalism i svensk barnlitteratur?
The purpose of our master thesis was to investigate how a multicultural society is reflected in childrens books picture books, books for children and young people, published in 2002. We found this issue interesting since children of today experience a change in society, where people of many ethnicities, cultures and religions live together to a greater extent than before. Since children in their everyday life are exposed to these different cultures, we think they also should be exposed to them in the books they read. In order to enhance an understanding of why such books are important to children, especially immigrant children, we have in our thesis included a passage with childrens linguistic development, identification and stereotypes. Other passages concern libraries and their roles in a multicultural society.
Döva och normalhörandes bedömningar av manipulerade illusionsbilder
Abstract
The present study examined if early deaf people and people with severe hearing
loss perceive visual information differently than hearing people. An experiment
was conducted with eight deaf participants and eight participants with normal
hearing. The participants were between the ages of 18-74 years. The
participants were asked to look at fifteen different images portraying
manipulated illusions, and then assess if the images were of the same size.
Subsequently another image depicting a different illusion with a face hidden in
it was presented to the participants.
