Hållning av unga svenska islandshästar och dess påverkan på beteende hos tvååringar :

Icelandic horses are becomming increasingly common in Sweden. The owners of Icelandic horses in Sweden usually believe their horses to be different from other breeds. Icelandic horses are predominantly considered to be less reactive, less neophobic and easier to handle than other breeds. Swedish owners of Icelandic horses also usually try to house and handle their horses in a way similar to the traditional extensive Icelandic way. There are no scientific studies of breed differences between Icelandic horses and other breeds, or of the housing of Swedish Icelandic horses.

Normativa värden för läppkraft hos barn mellan fem och tio år : Relaterat till bilabial stavelseproduktion

Lip force has been found to affect the ability to achieve satisfying speech production and swallowing. A normative value for lip force in adults has been measured to 15 Newton (N). Corresponding value for children measured with Lip Force Meter 100 (LF100) does not exist. In the current study lip force was measured in children between the ages of five and ten years. The aim of the study was to obtain normative values for children with typical development in separate age groups.

Effekter av kön, ålder och region på sjukpenningen i Sverige - en variansanalys

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.

Omvänt Förvärv, ett fenomen på First North : en studie i skillnader mellan bolags sätt att ta sig till Nasdaqs tillväxtmarknad

New companies go public through Nasdaqs growth market First North constantly. The reasons for going public are many, and the interest at the moment is big. There are different ways to go public, the most common being the traditional IPO. This study is about the companies that have been listed on Nasdaq First North between 2008 and 2013 through traditional IPO, or by RTO (reverse takeover).The differences between these two ways of going public are that the IPOs are reviewed more thoroughly by Nasdaq and the market. This makes the study interesting, as the RTOs go public in a faster way, and avoid the review from outside parties largely.

"Självet" och att bli sig "själv" : Sören Kierkegaards process och reflektion sedd med den positivistiska och negativistiska metoden

What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.

Den planerade undervisningen om det finska kriget : En studie av hur gymnasielärare i Västerbotten och Österbotten planerar att undervisa om det finska kriget 1808-09

This study examines how upper secondary school teachers in Västerbotten and Österbotten plan to teach about the Finnish War 1808-09. The study includes written interviews with nine teachers in Västerbotten and eight teachers in Österbotten, who have answered questions concerning school policy documents, content and didactic methods. The purpose has been to examine whether there is a difference in historical culture in how the war is treated in the two regions. Historical culture is here meant within the prospective history lesson, where the pupils encounter history within certain boundaries.The result of the interview study shows that there are differences in structure concerning the school policy documents, but that these differences on the whole are compensated by the widespread interest in the Finnish War by the teachers in both regions. The differences in historical culture can be found within the construction of the content when it comes to the aftermaths of the war as well as the purpose of the teaching.

Hur tänker barn att de ser ut inuti? : Vad har 3- och 4-åringar för uppfattning om insidan av kroppen?

AbstractMy purpose of this essay was to discover three- and four-year-olds comprehension of their internal body and then compare the result between their ages. I have used the same methods in both essays, semi-qualitative interviews. It is structured interviews with space for following questions. My formulations of the questions were: Do the children have a comprehension of their internal structure of the body? Do the children have a comprehension of organs and organ systems? Is there any difference between the ages?Their comprehensions I have categorized in four categories and I have seen age related differences in their comprehensions.

Påverkar tidighetstyp fiberhalten hos rödklöver?

The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.

Eurolution : Har internhandeln i euroområdet ökat sedan euron infördes?

Denna undersökning ämnar utreda huruvida euroinförandet år 2002 medfört ökad internhandel i EMU. Undersökningen analyserar handelsstatistik från år 1998- 2008 för de femton länderna som vid euroinförandet var medlemmar i EU. I analysen studeras två grupper av länder; en innehållande EMU- länder och en kontrollgrupp innehållande länder som inte infört euron. För att kontrollera för underliggande faktorer som exempelvis konjunkturella förändringar och preexisterande handelsskillnader genomförs två difference- in- difference analyser. Undersökningen finner inget statistisk signifikant resultat på en ökad internhandel i EMU efter euroinförandet.

Annons eller PR : hur vet kommunikatören vad som skall väljas?

Problem Faith in the power of advertising has varied largely through the ages, and since we know that advertising is paid for, it therefore has less weight than the usual news. Publicity through promotional activities is in turn difficult to control. The question which of these two ways to communicate with the market that is the most effective, is equally entitled to ask, as difficult to answer. Purpose/Aim This paper is designed as a pilot study with two different objectives that go hand in hand. The first overall aim is to investigate how advertising and PR / publicity can be measured with the same tools while designing this metric.

Ledde Kommunals strejk år 2003 till ett överutnyttjande av tillfällig föräldrapenning för vård av barn? : en empirisk undersökning

I uppsatsen undersöks hur Svenska Kommunalarbetarförbundets strejk våren år 2003 påverkade uttaget av tillfällig föräldrapenning för vård av barn (VAB). Min hypotes är att denna strejk leder till ett överutnyttjande av förmånen. Uttaget av VAB jämförs mellan de kommuner där dagbarnvårdare och barnskötare gick ut i strejk och de kommuner där detta inte hände. Genom att använda en difference-in-difference metod som kontrollerar för kommunspecifika och tidsspecifika faktorer finner jag att det totala uttaget av VAB signifikant minskar i de strejkdrabbade kommunerna. Under vissa antaganden kan man dock visa på en signifikant ökning i överutnyttjandet av VAB-förmånen..

Träning av sydafrikansk pälssäl och afrikansk stäppelefant på djurpark - skillnader och likheter

Training of zoo animals started when the first zoo opened in 1752. The difference between then and now is that from the beginning the zookeepers did not focus so much on animal welfare. Nowadays animal welfare is the most important thing in the training. Therefore, the zookeepers are training the animals mainly for veterinary purposes and activation. The training makes the animals less stresses during handling. When the zookeepers started to train elephants they used unpleasant stimuli such as a whip when the elephant did something wrong.
