Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende
Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.
Vaccination against boar taint - effect of restrictive and semi ad libitum feeding regime on production and behavior
Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.
Pansarvärnshelikoptrar : Ett instrument för manöverkrigföring?
Mellan år 1987 och 2000 fanns ett beväpnat helikopterförband inom arméflyget. Dessa två pansarvärnshelikopterkompanier användes för att bekämpa stridsfordon. Efter nedläggningen har Sverige inte haft en helikopter med beväpning för annat än egenskydd.Uppsatsen syftar till att utifrån William S. Linds teori om manöverkrigföring utvärdera om pansarvärnshelikopterkompanierna framgångsrikt bidrog till att besegra motståndaren.Det framkommer att pansarvärnshelikopterkompaniernas taktik väl stämmer överrens med Linds teori vilket pekar på att bestyckade helikoptrar är ett mycket användbart instrument inom manöverkrigföringen. .
Smärta hos djur :
We have made a litterature study about pain in animals. In this studie we have brought up
areas like sign of pains in animals, pain relief and the care perspective.
Pain is perceived when body tissue is damaged or nearly damaged by stimuli. Nociceptors,
which are receptors placed at nerve endings, responds to a provocation of pain and
transmit an impulse along the nerve to the brain via the spinal cord. Pain is urgent or
chronic, and can be divided into nociceptive pain (somatic pain and visceral pain) and
neuropathic pain. Different pain mechanisms can arise, such as referred pain, which is
when signals of pain are referred to other parts of the body.
?Vi kanske glömde ställa frågan till killarna??- Skolkurativt stöd till killar med självskadebeteende: Definition, problembild och förståelse
The main purpose for this study was to examine how boys with destructive and self-harming behaviour are perceived and comprehended by school counsellors and literature. The study assessed how boys who harm themselves are defined both in practice and in theory by using a social constructivist point of view and a gender perspective. The study was divided in two parts concerning gathering knowledge of the matter. The authors, using a method called qualitative semi-structured interviews, interviewed nine school counsellors. To acquire scientific knowledge, the authors implemented a literature review and researched books and journal articles regarding boys who self-harm.
Inverkan av ensilagets partikelstorlek på beteende och beteendestörningar hos mjölkraskvigor :
Modern milk production have come a long way when it comes to accommodating the
nutritional and physiological needs of the animals, but unfortunately the behavioural and
psychological needs of cows and heifers are often left unfulfilled. A long time for eating
is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours.
The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the
breeds SR and SF were housed in 8 slatted floor pens.
UNGDOMAR OCH ALKOHOL : - En fråga om attityd?
Syftet med studien var att undersöka ungdomars uttryckta attityder gentemot alkoholrelaterade handlingar samt att ta reda på hur de upplever den subjektiva normen från föräldrarna. Frågeställningarna var: Vilken attityd uttrycker ungdomen gentemot alkoholrelaterade handlingar? Hur uppfattar ungdomen den subjektiva normen från föräldrar och vänner när det gäller alkoholrelaterade handlingar? Finns det något samband mellan ungdomens uttryckta attityd gentemot alkoholrelaterade handlingar och upplevelsen av föräldrarnas attityd gentemot alkoholrelaterade handlingar? Hur skiljer sig de uttryckta attityderna åt mellan ungdomarna beroende på kulturell bakgrund och kön? Den kvantitativa utgångspunkten valdes för studien och Theory of Planned Behaviour användes som teoretisk utgångspunkt. Resultatet visade att respondenterna uttrycker främst negativa attityder gentemot alkoholrelaterade handlingar. Respondenterna upplever en negativ subjektiv norm från föräldrarna.
Konsumentbeteende vid köp av färsk fisk : en kvalitativ studie för utveckling av ett produktkoncept hos ICA
Health and convenience trends dominate the food industry and retailing business of today.
The health consciousness is spreading while appealing product attributes concerning taste and
packaging also are increasingly important. At the same time, the competition is growing fierce
in the Swedish market with hard discount formats and niche concepts who also are trying to
provide the market with perishables. Therefore, the pressure to lower prices is increasing
making economies of scale and rationalization progressively more important.
In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently,
many stores went from in-store cutting-up and packaging to selling centrally packaged and
distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere
packages and needs to increase the knowledge about the market and the consumer.
Dold marknadsförings effektivitet i sociala media
In this paper the authors examine three questions: 1) Is stealth marketing messages posing as status updates on Facebook a more effective way of advertising than traditional web banners? 2) What impact has learning about stealth marketing practices in social media on consumer attitude and post purchase behaviour? And finally 3) Will different generations respond differently to these questions?Our findings show that stealth marketing in social media is not more effective than traditional web banners. Furthermore, the result indicates that when consumers find out about stealth marketing practices it will have a negative impact on future purchase intensions and brand image. Most consumers will also have strong feelings of being deceived, which could instigate harmful post purchase behaviour such as negative word-of-mouth and possibly, based on some earlier cases, boycotts.The result of our research shows that the brand perceptions and future purchase intentions of Generation Y, persons between 18 and 30 years of age, are affected in a less negative way than the brand perceptions and future purchase intentions of older generations when finding out about stealth marketing practices in social media. However Generation Y:s reaction is still negative and they do consider traditional web banners to be more credible than status updates on Facebook.
?Anti-vertigo-systemet behöver kalibreras? : En undersökning av Bamsetidningens läsbarhet i förhållande till målgruppen
Learning words have shown to be a very crucial part of learning a second language and the one most important factor to make pupils with Swedish as a second language succeed in school. To make sure that all pupils get the right conditions to learn from all subjects and their entire content a wide vocabulary is necessary. Even so it is found that there are shortcomings regarding this kind of teaching in Swedish schools.Through interviews and observations of two teachers that teach pupils with Swedish as a second language, and also with a short reading test for the pupils, the possible strategies that these teachers use for learning words have been studied. The result shows that the teachers are using several strategies and that they are actively working with transmitting these to the pupils, but there are some areas that need developing..
Den h?gerpopulistiska paradoxen: Varf?r st?djer personer med invandrarbakgrund Sverigedemokraterna? En kvantitativ studie om h?rkomsten och medborgarskapets p?verkan p? st?det av radikala h?gerpartier bland invandrare
During the last decade millions of people have migrated to Europe. Parallel to this
development, we see that many countries are becoming more hostile towards immigration.
The success of radical right-wing parties (RHP) has been accredited to natives within the
receiving countries turning to RHP to reduce their perceived threat from immigrants.
Paradoxically, the RHP-support has also increased significantly among the immigrant
population given the common assumption that immigrants are in solidarity with regards to
shared experiences of immigration. In this dissertation, I argue for the importance of
considering the increased RHP-support amongst immigrants, something that has been
neglected in contemporary research.
Att som missbrukare inte vilja leva mer - om samband mellan missbruk av alkohol och droger och suicidala handlingar
The purpose of this study was to explore the connection between substance abuse and completed/attempted suicide. Central questions were who the substance abusers who commit suicidal actions were. The study also tries to find out which factors that contributes to this behaviour and why it is so common amongst substance abusers. All from the point of view of three scientist and three persons working with treatment of addicts who were interviewed. The results of these interviews were analysed on an individual level with a psychological theory.
Palestinsk terrorism under Osloprocessen
Denna uppsats behandlar ämnet terrorism under Osloprocessen, som varade under i princip hela 1990-talet. Vi har valt att undersöka denna terrorism ur ett relativt avgränsat perspektiv. Vi vill se på ämnet ur ett orsak och verkan perspektiv, och detta gör vi genom att analysera fram de konsekvenser som Israels hantering av den palestinska terrorismen gav. För att utkristallisera ett mönster i Israels anti-terroristpolitik har vi applicerat en handfull olika teorier, som behandlar olika former av terroristhantering, på händelserna under i Mellanöstern under Osloprocessen. Huvudtesen formas av att vi ställer inkludering och exkludering av terrorister, i fredsamtal, mot varandra och försöker pröva deras för- respektive nackdelar..
Strategi och kapitalstruktur - Finns det en ömsesidig påverkan? En studie av svenska börsnoterade modebolag
Syftet med uppsatsen är att öppna upp en diskussion kring frågan om huruvida ett företags pris- och outputstrategi och tillväxt påverkas av eller påverkar kapitalstrukturen i samma företag.Vi har utifrån en deduktiv ansats använt oss av både kvalitativ samt kvantitativ data.Vi har valt följande begrepp och teorier för att förklara sambanden mellan kapitalstruktur och strategi: Aggressiv och defensiv strategi, konservativ och offensiv strategi samt Limited liability, Predatory behaviour och Investment effect theory.Vi har genom kvantitativ data samlat in sekundärdata från respektive företags hemsida samt från deras årsredovisningar. Genom kvalitativa metoder har vi samlat in primärdata i form av telefonintervjuer.Våra resultat tyder på att det kan finnas ett samband mellan kapitalstrukturen och de aspekter av strategi som vi valt att undersöka. Dock kan vi inte dra några generella slutsatser då vår population är alltför liten. Vissa av de teorier som vi har byggt vår uppsats på behöver utvecklas för att passa på ett tillfredsställande sätt till detta problem..
Könsförvirring : En narrativ studie av normbrytande genus i barndomen
This essay deals with non-normative gender expressions during childhood. I?m using narrative theory and methods to analyze autobiographical narratives. My questions are:What strategies does the non-normative person use to deal with his otherness?Using the methodological analysis tool ?turning point?, where are the turning points in the narratives? Are their any common turning points in the various narratives?Where is the responsibility placed in the narratives for that someone does not fit in by the adults/ staff at the school/kindergarten- on the non-normative person or at the surroundings?The experiences are interpreted through theories and concepts from queer theory and gender theory.
