Hundägares och kattägares relation till sitt djur :

The relationship between the pet and it's owner is a very important and interesting issue. Unfortunately there is not so much research on this and in addition to that Swedish veterinarian education does not put much emphasis on pet's role in society or their pattern of behaviour nor treatment. This thesis is based on an opinion poll that 20 dog owners and 20 cat owners contributed. The main purpose of the thesis was to compare the relationships that the pet (dog or cat) and its owner can have. The issues such as the pet owner's attitude to his/her pet, how the pet owner percieves and interprets the signals from the animal, and what they think about the natural behaviours and needs that their pets (might) have. The results show that dog- and cat owners are people who generally love animals, that they used to have even other animal species in the past, but when it comes to choice between a new dog or a new cat they choose the one that they previously have had and that they are used to. Most of a dog owners choose the dog to be their pet because of the company while the majority of a cat owners choose cat because cats are independent and they are used to cats.

The cow eye-Function and effect of light on milk yield

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Pairs trading : En studie på den svenska aktiemarkanden, 1995-2004

Pairs trading is a relatively new trading strategy, the strategy has only been used during a couple of decades. A study made on the American stock market has shown that the strat-egy has generated a positive result. The purpose of this thesis is to investigate if pairs trad-ing has been able to create a positive result on the Swedish stock market during the time period of 1995-2004.The data required for this thesis was collected from Stockholm stock exchange and is ad-justed for splits and issues.The pairs trading strategy involves two stages ? identification of pairs and trading signals. The pairs were identified during a period of 12 months.

Vad kännetecknar en bra röst? : En studie om röster i kommersiella sammanhang

Vad kännetecknar en bra röst? Denna studie syftar till att utröna huruvida det finns något i den akustiska talsignalen som kan säga något om vilken uppfattning lyssnaren bildar sig om talaren. I kommersiella sammanhang är sättet att förmedla viktigt för att ge lyssnaren rätt budskap och i detta är rösten ett viktigt redskap. Grunden till föreliggande studie var att låta en grupp lyssnare bedöma några olika röster samt att analysera rösterna akustiskt, varefter en jämförelse mellan resultat från lyssnarbedömning och akustisk analys gjordes.En kvinna och en man i grupperna professionella samt icke-professionella röstanvändare läste in en standardtext. Inspelningarna analyserades akustiskt och bedömdes perceptuellt av en lyssnargrupp, omfattande 10 individer utan röstprofessionell kompetens.

Självskadebeteende i skolvärlden : En kvalitativ studie kring skolkuratorers upplevelser och uppfattningar av självskadebeteende hos högstadieelever.

This study is of a qualitative phenomenological approach. Its background lies in recent reports that show the problem of self-harm increasing among adolescents. The intent of the study was to highlight school counselors? view of self-harm, and their experiences of meeting self-harm through their work. Six school counselors, all employed in secondary school, have participated in semi-structured interviews.

Individuella utvecklingsplanens inverkan på undervisningen vid högstadiet : Specialpedagogers uppfattning om den individuella utvecklingsplanens integration vid högstadiet

The aim of this essay has been to find out whether the individual development plan does make it easier to teachers to discover any needs of the students to get education or material changes and by that make adjustments in the classroom. I chose to seek information by interviewing special educators at four compulsory schools, since they have an overall apprehension of how the work is carried out at the school, especially the work with students in need of any form of extra support.All students at the Swedish compulsory school shall have an individual development plan. The purpose with the plan is, besides that the student is to be given possibilities to form his own pedagogical and social goals, that the teacher shall get early signals if a student may be in need of getting education and materials changed and adjusted for to easier manage his studies. The individual development plan of the student should have the function as a tool to the teacher to facilitate for his students.The answer of my question can be sum-up in a no, the inherent potential in the individual development plan is not utilized by the teachers that seem to have the apprehension that the plan is for the student all by him/herself. The teaching staff has obviously not understood the use they can get out of it. .

Grooming behaviour in the Red-tailed guenon

The behaviour of the red-tailed guenon (Cercopithecus ascanius) was studied over the course of nine days in the Sabaringo forest surrounding Kichwa Tembo Tented Camp near the Masai Mara National Reserve, Kenya. A focal animal instantaneous sampling method with a one minute interval was used to record the behaviours of the monkeys for approximately 12 hours a day, the day being divided into six shifts á two hours. This method has proven successful in earlier studies of red-tails in this area. The study subjects included both lactating and non-lactating females, juveniles and on some occasions the resident male. The purpose of this study was to examine the grooming behaviour of red-tailed guenons and whether or not the occurrence of grooming varies depending on monkey type (lactating or non-lactating) and time of day.

Information och signaler i revisionsberättelsen : En studie av konkursdrabbade företag i Skåne län

The requirement on audit was introduced when ownership was separated from management. The situation that arouse was that not only the owners, but also the stakeholders, required information about the company?s financial position. On this basis the audit would contribute to quality assurance of the financial information. One of the auditor's functions is to assess an ongoing stakeholder opinion.

Utveckling av metod för utvärdering av synnervens funktion hos häst :

VEP, visual evoked potential is an electrophysiologic test that can be used for evaluating the higher visual pathways. The aim of this study was to investigate if it is possible to adapt this method to horses. This method could have a clinical use in addition to the existing diagnostic methods that are available to evaluate vision in horses. Firstly, this study contains a summary of relevant studies done on animals and, secondly, an experimental part where the possibility of recording VEP in nonsedated and sedated horses is investigated and where to position the recording electrode to obtain the best results. Our results show that it is possible to record VEP in horses in a clinical setting. VEP was best recorded in the sedated horse to avoid movement artifacts and other disturbances.

Identitetsskapande på Internet : En kvalitativ studie om det sociala nätverket Facebook

As computerized communication and the Internet have evolved, the possibility to express and affirm one?s identity in new ways has also been created. Facebook, which has taken a leading role among the social fora on the Internet and succeeded worldwide, is my choice of study due to the number of people that actively choose to present themselves on it. The purpose of this thesis is to study the identity construction on Facebook through the activities a member partakes in, as well as how the presentation of oneself is written and if it is a result of a self-reflective process of the individual.The rationale for the qualitative study has been personal interviews in order to get an insight into how the individuals use and present themselves on Facebook and - in the interaction with others ? how they construct their own identity. My hypothesis has been that we, in the interaction with others, have a great possibility to create and understand our own identities. The study results show that identity formation is a constant process and that it is indeed a self-reflective project.

Akustik och säkerhet i inomhusarenor

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

"Lets Play!" : En studie av kunskapsöverföring mellan digitala spel och musikinstrument.

The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.

Undersökning och utformning av ett generellt datainsamlingssystem i LabVIEW

This report is the result of a diploma work made at IMT at US in Linköping. The purpose of this piece of work is to investigate the possibility to design a general program for data-acquisition using LabVIEW, suiting different hardwares and connections. Great importance has been attached to communication with serialport, using bluetooth, because different wireless PPG-instruments has been developed parallel to this project. These PPG-circuits uses this type of serialcommunication. Communication with USB, GPIB and analog connection has also been examined and analog communication has been tested practically.

En studie av en misslyckad implementering av förbättringsmetodiken Six Sigma: Tre avgörande faktorer

The improvement programme Six Sigma has often been surrounded by an air of success since it was introduced in the 1980s. Yet there are cases in which introduction of the Six Sigma improvement programme show far from successful results, even complete implementation failures with no traces of the Six Sigma methodology or any improvements after completion of the introduction. These failures can cause severe damage to organizations through direct monetary loss caused by a negative result of the investment. Indirectly the failure can cause confusion in the organization and loss of employee motivation. The conclusions have been derived based on a qualitative case study at a Swedish telecommunications company.
