Brunbjörnens (Ursus arctos) inverkan på den nya svenska älgförvaltningen

The European Brown bear (Ursus arctos) has gone from basically being extinct in Sweden to, 2008 being estimated to a total of 3298 individuals. When looking at the new Swedish moose management system it is important to have an ecosystem-based approach and therefore include all the parts that moose impacts on and from in the management, especially the brown bear. Primarily in the spring and early summer the brown bear is a significant predator on moose calfs which must be taken into account in moose management. When the bear recolonize areas that it has previously been eradicated from, it will once again come in contact with people who are not accustomed to the bear's role in the ecosystem. We studied three groups of moose management areas with different predation by bears.

Ekologisk slaktgrisproduktion i Sverige :

This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.

Adaptiva metoder för systemidentifiering med inriktning mot direkt viktoptimering

Direkt viktoptimering (Direct Weight Optimization, DWO) är en ickeparamterisk systemidentifieringsmetod. DWO bygger på att man skattar ett funktionsvärde i en viss punkt genom en viktad summa av mätvärden, där vikterna optimeras fram. Det faktum att DWO har en inparameter som man måste veta i förväg leder till att man på något sätt vill skatta denna inparameter. Det finns många sätt man kan göra denna skattning på men det centrala i denna uppsats är att skatta inparametern lokalt. Fördelen med detta är att metoden anpassar sig om till exempel systemet ändrar beteende från att variera långsamt till att variera snabbare.

Tamillern : beteende, hantering och omvårdnad

This essay is intended for veterinary nurses and its purpose is to contribute to an increased knowledge about the ferret and there by a better nursing care at clinics. The essay discuss in briefness origin and earlier use of the ferret but also anatomy, physiology and reproduction. The senses of the ferret, as vision and hearing, are described in connection with behaviour. The part of the essay where nursing care is described bring up procedures as handling when collecting blood, medical techniques and how the clinic best should be suited for these animals. The main part of the essay is based on literature studies but it also contains a study visit at Blå Stjärnans animal hospital in Göteborg. 23.

Den trojanska bloggen : Bloggreklam, en effektiv marknadsföringskanal?

Purpose  The purpose of this paper is from a consumer perspective analysis whether or not blogs are affecting a customer?s purchase behaviour to a larger extent compared to traditional marketing methods through TV commercials. Additionally, within the scope of this try to identify the type of consumers that are more influenced to a purchase decision by blog contents compared to others.Methods Through a quantitative approach this study will examine the effectiveness of advertising in blogs. A survey was used in order to collect data where the respondents corresponded to the population in Sweden in the ages 15-79. Initially the size of the blog audience was estimated and thereafter it was examined how many of these that were affected towards a purchase decision by blogs.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Skärgårdskvinna under efterkrigstiden: en studie om levnadsvillkor i förändring

Den här uppsatsen handlar om levnadsförhållanden bland kvinnor som är eller har varit verksamma inom någon skärgårdsbunden näring i Norrbottens skärgård. Den fokuserar på de förändringar som arbetsförhållandena och det sociala livet genomgått under perioden från andra världskrigets slut fram till idag, 2006. Jag, som forskare och uppsatsförfattare, har försökt nå denna kunskap genom att söka svar på frågor om hur kvinnornas ställning har förändrats i arbetet, i familjeförsörjningen och i det sociala livet. Metoden som använts är kvalitativ och baserad på semistrukturerade intervjuer och kategorianalys av citat tagna från intervjutranskriptionerna. Teorier som använts är Due Billings och Alvessons kritiskt tolkande perspektiv på genus/kön, samt Zollinger Gieles och Holsts omarbetningar av Talcott Parsons begrepp adaptive upgrading, integration, inclusion och goal differentiation.

A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

Musik och genus - Hur genus konstrueras i musikundervisning

Syftet med den här uppsatsen är att undersöka hur genus - vårt socialt skapade kön skapas i en musikpedagogisk verksamhet. Finns det någon skillnad mellan pojkar och flickors intresse i ämnet musik, val av instrument eller agerande i undervisningen? Hur bemöter eleverna varandra, hur bemöter läraren eleverna och tvärtom ur ett genusperspektiv? Studien utfördes på en grundskola i klasserna sju och nio med hjälp av observationsmetoden och videokamera. Resultaten visade på skillnad mellan könen genom att pojkarna generellt dominerade musiklektionen genom att prata, bråka och ta mer uppmärksamhet än flickorna. Undervisningens innehåll och lektionstid blev kraftigt negativt påverkad då lärarens uppmärksamhet riktades åt pojkarnas bråk.

Lokal samförvaltning i Tivedsbygden : en svårfångad vision om hållbar naturresurshantering

Föreliggande kandidatuppsats handlar om att söka beskriva samverkan och konflikt i samband med naturresurshantering. Undersökningens forskningsobjekt är ett försök till lokal samförvaltning som togs av lokala invånare i Tivedsbygden, en skogsbygd i gränslandet mellan Västergötland och Närke. Visionen om detta hållbara naturresursarrangemang lyckades dock aldrig nås. Initiativet togs i samband med ett landsbygdsutvecklingsprojekt pågick under åren 2009-2011. Min tolkning är att detta försök präglades av samverkan och konflikt.

Jämförelse av icke-kryptografiska hashfunktionerför användning i hashtabeller

This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.

Murbruket i mångfaldens mosaik - en fallstudie av framgångsrikt ledarskap i mångfaldsgrupper på Swedbank

Successful diversity management has become an increasingly pressing concern for companies and organisations, as the workforce has grown more diverse over the past few decades. Research on whether increased work group diversity has a generally positive or negative impact on results remains inconclusive. It has, however, been established that good diversity management is pivotal in creating conditions for the successful performance of diverse work groups. Although much attention has been directed towards explaining the translation of work group diversity into positive results, less attention has been given to the processes that underlie this translation and the way it is expressed in everyday leadership behaviour. This thesis revolves around a case study, at the Swedish bank Swedbank, which combines qualitative and quantitative elements to explore the successful leadership in nine diverse work groups at the local branch level.

We found thattheese three themes were central: Language, Content and the feeling of beingAnonymous.

Hur forskare forskar - hur doktorander använder bibliotek i sitt arbete

In this bachelor thesis the aim is to explore how university libraries and researchers function together. I will do this through interviews with phd students and examine how they reason on the use of libraries and other resources available in campus and witch other methods they use to gather information. The graduate students differ in where they are with their research process, but all of them work in the field of social sciences. To help me in my analysis I have adopted Wilsons model of information behaviour and modify this to better suit my purpose. My findings show that they mainly use the library to access materials and avoid use of the librarians, due to perception of low usefulness.

Utnyttjandet av ligghallar hos dikor och kvigor av köttras under vintern :

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.
