"Jag brukar jämföra källor med varandra." : En studie i gymnasieelevers kritiska tänkande
The main purpose of this bachelor thesis is to examine the existence of criteria and to what extent high school students use these criteria when they are collecting information for a school assignment. I also compare students attending different high school programmes with each other and compare students on different levels of education.I have done a quantitative study with 284 students in which the students have filled out questionnaires.The result shows that the most common way to evaluate information is to compare sources with each other. Students also look at how the information is written, and they want the information to be detailed and easily available. More seldom used criteria include consideration of the authority of the writer, determination of how up to date the information is, and gauging the perspective of the information.The result also shows that students attending a high school programme that prepares them for higher education are better at evaluating information than students attending a high school programme of vocational preparation. Students at a higher level of education are also better at evaluating information than students at a lower level of education. .
Lättridningens påverkan på hästens rörelsemönster i trav :
The interest in horses and equestrian sport is constantly increasing, and so is the will in both riders and trainers to learn more about the effect the rider and its equipment have on the horse. The last twenty years, more and more studies have been performed were the horse and its kinematics have been in focus. The access to more advanced technology has made it possible to study areas, which earlier have been hard to reach. The knowledge about kinematics in the horse, and how riders and their equipment interact with the horse?s movement, is also of great interest to veterinarians in equine practice.
Fysisk aktivitet = psykisk stabilitet? : En undersökning om relationen mellan mängden fysisk aktivitet och självupplevd hälsa
AimThe purpose of this study was to investigate the relationship between self-perceived health and level of physical activity among the staff at The Swedish School of Sport and Health Sciences (GIH). We focused on the following questions:How does the amount of physical activity affect the self-perceived health among the staff at GIH? Are there any gender differences in self-perceived health following the amount of physical activity? Do the self-perceived health and the amount of physical activity differ between the various age groups? Are there any differences between the staff responsible for health education compared with the other staff?MethodWe chose a validated questionnaire for our study. It was a combination of two already previously validated questionnaires together with our own supplementary background questions. The questionnaire was presented to 96 respondents and we received 76 answers.
Anknytningsmönster, copingstilar och stress inom relationsintensiva yrken : En kvantitativ studie rörande sambanden mellan anknytningsmönster, copingstilar och arbetsrelaterad stress
There has been a dramatic increase in long-term sick leave in Sweden, which largely depends on occupational stress. Occupational stress applies particularly in relationship-intensive jobs, which means that the individual works with a lot of contact or responsibility for other people. Research has shown that attachment is relevant to the choice of coping style and perception of stress in the workplace. The aim of the present study was to investigate the relationships between attachment patterns, coping styles and occupational stress in relationship-intensive jobs and to extend previous studies by adding the variables age, work experience and education in relation to coping styles and occupational stress. The study was in quantitative form in which 186 participants from various relationship-intensive jobs across Sweden participated.
BILD OCH MATEMATIK ? TV? KREATIVA ?MNEN. Om interdisciplin?ra samarbeten i gymnasieskolans estetiska program
This study aims to provide a comprehensive understanding of interdisciplinary
collaborations between Art and Mathematics within the Arts program at the upper
secondary school level. Grounded in sociocultural theory, this study explores
learning through language, action, and context, drawing on the works of theorists
such as Lev Vygotsky (1995/2016), John Dewey (1897/2011) and Roger S?lj?
(2020). Through semi-structured interviews, educators in both Art and
Mathematics discuss shared subject content and explore opportunities and
obstacles in fostering a collaborative culture within the Arts program at the upper
secondary school level. The study reveals common subject content in Art and
Mathematics suitable for interdisciplinary collaboration.
Nivågruppering i Engelska : En fallstudie på en gymnasieskola i en Stockholmsförort
The purpose of this degree thesis is to investigate what the English teachers in an upper sec-ondary school, think about teaching students in ability grouped classrooms. The questions that I have set out to investigate include what the teachers think about ability grouping in English, the school?s current organisation of ability groups, the pros and cons of ability grouping in English, differentiation in teaching and if students get more individualized teaching with abil-ity groups, how the teachers cooperate and what would be the optimal teaching situation in an English learning classroom.I did a lot of theoretical research on the subject and studied old essays on similar subjects. I also did some classroom observations to use as background information for my interviews. I interviewed five teachers of different sex, age, and teaching experience.

Fem godkända elever är fler än fyra väl godkända : En statsvetenskaplig studie i skolans förvaltningspolitik
This study aims to analyze four gymnasium teachers? opinion on the values within the Swedish school system today, as well as the presence of conflicting values and goals in their role as a street level bureaucrat. A comparative aspect concerning private and state regulated schools was implemented into the study in order to compare one school system to the other. This was achieved by using semi-structured interviews with the aim to register the teachers? opinions on these matters.The study showed that the teachers perceive a high amount of discretion within their role as a street level bureaucrat concerning the educational aspect of their work.
Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft
The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
Analys av fiskerättsförhållandena i Stockholms skärgård i relation till känsliga områden samt fysisk störning
This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.
Analys av datakommunikationssäkerhet för VoIP-protokoll
Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..
