Importance of epigenetics in animal breeding : genomic imprinting

ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.

Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie

Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.

Vad har påverkat utvecklingen av den etiska klädmarknaden? - En jämförande kvalitativ studie av Storbritannien och Sverige

There is a growing interest for ethical consumption, in general as well as in the clothing industry. The consumption of ethical clothes is a complex phenomenon though, where aspects such as quality, style, function, price, time assets, accessibility and ethical attitudes affect the decision making. Researches that have been executed show the diversities in development between different countries. There are fairly strong indications that the ethical clothing market is more advanced in the United Kingdom than in Sweden and therefore these two countries are objects of this research. The aim with this thesis is to describe and explain what have affected the development of the ethical clothing market in the United Kingdom compared to Sweden. For that reason a qualitative approach has mainly been used, where deep interviews with people within the ethical clothing industry have contributed to most of the empirical part. As a complement secondary data such as statistics of the two countries have been used in order to investigate our area. One useful tool, among others, to investigate the macro environment is the SLEPT model.

En uppföljning av floran i Enköpings vattenpark : kan anlagda våtmarker med vattenrening som huvudsyfte bidra till naturvård och biologisk mångfald?

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

Say no to racism?: FIFAs antirasism ur ett postkolonialt perspektiv

The purpose of this thesis is to historically describe how Fédération Internationale deFootball Association (FIFA) interprets how the discourse of anti-racism has developed withintheir own organization throughout the years. In doing so, the thesis lands in a present timeperspective and then aims to identify the norms which FIFA, according to the organizationitself, stands for in regard to anti-racism within world football. That standard of behavior isthen put in contrast with the hidden ideological conceptions which, with the applying of apost-colonial perspective, can be found in the rhetoric used by FIFA in expressing themselvesabout their anti-racism stand.The methodology used in this thesis builds upon a qualitative text analysis approach inwhich solely primary sources available through the official website fifa.com are considered.The study finds that anti-racism is a relatively young concept within FIFA and that the communicatedideal standard of behavior circles around terms such as unity, diversity, solidarityand equality. Further on, FIFA clearly articulates how the universal power of football as suchcan unite people and that FIFA, as the administrator of this the world?s greatest sport, can setan example for the rest of the world to follow when it comes to notions of tolerance and solidarityin preventing racism in the future.In following the terminology provided by the post-colonial theorists Homi Bhabha andGyatri Spivak, and applying the concepts of fixity and essentialism on the rhetoric aroundanti-racism, the study discovers that FIFA, in sharp contrast to the articulated norms, in factexpress ideological conceptions of skin as a barrier of difference between people, and thatFIFA on good grounds can be accused of reproducing racist stereotypes rather than bridgingthem.The study concludes that its findings clearly demonstrates the increased need of consideringsports, and more specifically international sport organizations, as a basis for researchwithin the academic field of International Relations, and that a postcolonial perspective verymuch can provide alternative understandings of how these actors operate and what influencethey might have in the international system..

KRAV-grisar har fler ledanmärkningar än konventionellt uppfödda grisar.

Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.

Kulturmöten i vården: Sjuksköterskors upplevelser av att vårda patienter med annan kulturell bakgrund

Ungefär 14 procent av den svenska befolkningen utgörs av invandrare. Studier visar att många invandrare är utsatta i samhället då de kommer till ett nytt land. Denna utsatthet kan vara språksvårigheter, arbetslöshet, rasism och diskrimination. I samband med att invandringen ökar i Sverige ökar även sannolikheten att man som sjuksköterska kommer i kontakt med patienter med annan kulturell bakgrund. På så sätt kan det uppstå det kulturkrockar i mötet med invandrarpatienter.

Standardisera mera? : Z39.50 mellan enighet och mångfald

Z39.50 is a standard protocol designed to create an interface between diverse computer databases for diverse information needs. Since it has to be adjustable it is also complex and demands a certain degree of expertise when being set. However, the aim of this paper is not to make a theoretical description but to examine certain conditions in practice. From the perspective of Swedish research libraries two principal hypotheses are examined: 1) the implementation of a given technology (Z39.50) is primarily influenced by social circumstances, and 2) the way in which the technology is implemented will bias the results of information retrieval. For this examination we need a framework of theories concerning the relationship between technological development and society, organisational theories and database theories.

Förändringar i vegetationens sammansättning efter en våtmarksrestaurering : Changes in the vegetation composition after a wetlandrestoration

The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.

Dragare, täckningsgrader och önskelådor : systematisering och råd för grönplanearbete

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

Artrikedom av kärlväxter i övergivna och restaurerade hagmarker : betydelsen av igenväxningsgrad och tid sedan igenväxning började

Continuously grazed grasslands have remarkably high plant species diversity. In Sweden this type of habitat has declined for the last two centuries. Changed land use has caused habitat fragmentation and loss of habitat quality. This has caused a great number of plant species to end up on the verge of extinction. To try to save this unique habitat and the species that are tied to it, lots of resources are laid on restoration of abandoned grasslands. In this study, plant species richness of continuously grazed, abandoned and restored grasslands were related to degree of overgrowth, time since overgrowth started and rate of overgrowth.

"Malmös nya miljardkomplex" : Om strategisk kommunikation och förankringsmetodik i ett mångkulturellt samhälle

In May 2010 the plans for Malmö?s new Concert Hall, Conference Centre and Hotel were announced publically. The purpose of this thesis was to present strategy for communication in order to gain approval for the new concert and conference center from the inhabitants inMalmö and to incorporate the use of it in their everyday life.Material from the receiver?s as well as the sender?s perspective has been collected from qualitative interviews. Through group interviews we have investigated the general consensus of the inhabitants of Malmö regarding the investment, placing, offered events, expectations as well as how they collected information.

Ekonomi eller politiska beslut : Vad styr fristående gymnasieskolors lokalisering?

In the beginning of the 1990s the responsibility for the schools shifted from the government to the local authorities. This started an era with a freedom of choice for students where they themselves could choose which school to go to. The new system also opened up the possibility for independent private schools to exist side by side with local authority held schools. The overall aim of this study is to determine the factors that affect the location of these independent schools and the geographical pattern these independent schools create. The study in this paper is based on materials from statistics and interviews.

En sfär av mänskliga rättigheter : om mångfald och (o)likheter i svenska Amnesty

Fokus i uppsatsen är begreppet mångfald och svenska Amnesty. Utgångspunkten är dels det oproblematiserade och positiva talet om mångfald som kommer till uttryck i den offentliga debatten i Sverige och dels det faktum att den svenska sektionen av Amnesty International nyligen tagit beslut om att införa ett"mångfaldsperspektiv"i syfte att genomsyra all organisation och verksamhet.Syftet med uppsatsen är formulerat i två steg: som ett första steg analyserar jag uppfattningar och föreställningar om Amnesty som organisation, och om dess medlemmar och som ett andra steg gör jag - med särskilt fokus på etniska och kulturella aspekter - en analys av hur mångfald förstås i intervjuerna och hur denna förståelse relateras till svenska Amnesty som organisation. Kvalitativa intervjuer med sex aktiva medlemmar inom svenska Amnesty utgör grunden för analysen. Ett socialkonstruktionistiskt inspirerat synsätt används som teoretisk referensram och begrepp som etnicitet, kultur, mångkulturalism och kategorisering är centrala och används som teoretiska verktyg i analysen.De huvudsakliga slutsatserna av analysen är att den bild av Amnesty, och dess medlemmar, som kommer till uttryck i intervjuerna är nästintill uteslutande positiv, vilket får till följd att en diskussion om utanförskap och diskriminering i rörelsen inte ges något direkt utrymme. Mångfald förstås i mångt och mycket i termer av en representation av olika"kategorier"av människor såsom "män", "kvinnor", "invandrare", "icke-akademiker".

Avkastning som mål, diversifiering som verktyg för en lönsam styrelse

Forskning hävdar att endast ett fåtal av styrelseledamöterna förstår vilka beslut som är värdeskapande för företaget. En av orsakerna är oförmågan att rekrytera rätt personer och flera röster har höjts för att en diversifierad rekrytering till bolagsstyrelser är en möjlig lösning på problemet. Diversifieringen kan ske utifrån olika demografiska faktorer som på en aggregerad nivå ska medföra att processen från beslut till genomförande blir effektiv. Vi finner stöd för en ökad diversifiering hos styrelsen i en rad teorier som alla är en del av tankegodset inom bolagsstyrning.Syftet är att konstruera och applicera en teoretisk modell för en lönsam styrelsesammansättning utifrån existerande forskning. Studien begränsar sig till svenska bolag på OMXS30 under tidsperioden 2003 -- 2014.Med stöd av vår modell visar vår analys att styrelsens storlek uppvisar en positiv korrelation med företagets förmåga att generera avkastning på eget kapital.
