Privatiseringen av de växtgenetiska allmänningarna : Konsekvenserna av regimkomplexet kring växtgenetiska resurser för bönders rättigheter och matsäkerhet

This thesis discusses the global regime complex concerning the management of plant genetic resources for food and agriculture, and how different regimes concerning these resources cooperate or stand in opposition to each other. Because of changes in US patent law and the establishment of TRIPS, patent claims over plant genetic resources has increased dramatically globally. This, amongst other things, in turn has lead to the development of CBD which in turn lead to the creation of access and benefit laws in many countries. To create a free flow of genetic resources for food and agriculture the ITPGRFA, with its multilateral system, were negotiated. The aim of this thesis is to investigate which consequences the regime complex concerning plant genetic resources for food and agriculture can have on the rights of small farmers, agricultural research and food security in the global South.

Bevarande av de svenska lantraserna, populationsgenetiska och molekylärgenetiska metoder

Today?s community requires an increase in food production. Animals are today bred so that they produce more than their ancestors did. Production has been the most important and breeds with the highest production levels have therefore become popular. Many of the old local breeds have become extinct or are about to become extinct because of this trend.

Felaktig alternativ splicing: Vissa mutationer i BRCA1, BRCA2, ER? och ER? är starkt förknippade med bröstcancer

Alternative splicing is a process that partly rejects the common definition of a gene ? that one gene codes for one specific protein. By variable combination of coding regions (exons) and exclusion of non-coding regions (introns), formation of several different mRNA-transcripts, and consequently several different proteins, can derive from the same gene. Alternative splicing is an important condition for the development of complex life forms, but it is also a highly sensitive process and inaccurate splicing is the cause of approximately 15 % of mutations that cause genetic diseases. This article presents four genes, BRCA1, BRCA2, ER? and ER?, and inaccurate splicing of these genes increases the risk of developing cancer, particularly breast cancer and ovarian cancer.

Jaktprov hos brittiska stående fågelhundar

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

Förstudie för skapandet av ett miljöövervakningsprogram : en styrkeanalys angående vattendrag i västerhavets vattendistrikt för fastställandet av provantal i tid och rum för ett effektivt omdrevsprogram

The environmental monitoring in Sweden has been developed by several different parties and is now being coordinated and made more effective in order to meet the current demands on high quality information regarding the state of the environment. Sweden has been divided into five different water districts based on watershed areas because of requirements in the Water Directive of the EU. In Sweden there are two common types of environmental monitoring programs used to gather information on changes in time and in space. Currently both these two types are used for lakes in the water district of the western sea but only one is used for watersheds. The purpose of this report is to supply basic information regarding the possible need for a second environmental monitoring program for watersheds in order to better describe the spatial variation within the district as well as to determine the number of samples necessary in order to describe the district over time and space.

Mätegenskaper för fruktsamhet och modersegenskaper i fåraveln :

The aim of this literature review was to suggest suitable index traits to use in the Swedish Sheep Recording Scheme for fertility and maternal traits. Since fertility and some of the maternal traits are not normally distributed advanced methodology is needed to calculate genetic parameters. Breeding is a tool to improve the economy of the farm and for the selection of breeders estimated breeding values (EBV) for important traits are of high value. In sheep breeding both lambs born and lambs weaned should be taken into consideration as well as the ewe?s maternal ability, which includes lambing ease, lamb survival, ewe behaviour as mother and the early growth of the lambs.

Näthinnesjukdomar hos hund :

An array of different retinal disorders is present as a threat in quite a number of dog breeds. These often lead to profound visual impairment or blindness. Many of the disorders are genetic, and they are, in Sweden as well as in other countries, subject to breeding programmes. The anatomy of the eye and the retina, as well as current examination techniques (ophthalmoscopy, electroretinography (ERG) and genetic analysis) are described. The more common retinal disorders encountered in dogs in Sweden are discussed: retinal dysplasia, generalized progressive retinal dystrophy, retinal pigment epithelial dystrophy, collie eye anomaly, sudden acquired retinal degeneration, retinal detachment and choroiditis. The possibly affected breeds are listed. The value of diagnostic findings is discussed and current advances on the subject in ophthalmologic research are accounted for..

Idiopatisk epilepsi hos hund

ABSTRACT Epilepsy describes a neurologically caused condition which involves seizures. Epilepsy can be classified according to different types of causes and the nature of seizures can vary. Medication for epilepsy in dogs is limited in comparison with human medicine. Idiopathic epilepsy is the most common neurological disease and one of the most common genetic diseases in dogs. Because epilepsy has a higher prevalence in certain breeds, there is reason to suspect that it is a hereditary disease. The inheritance of idiopathic epilepsy is for most breeds not determined, except for a few variants of the disease.

Empirisk studie av Föreningssparbankens aktieindexobligationer

Abstrakt Syftet med uppsatsen är att empiriskt undersöka om Föreningssparbanken lyckats generera riskjusterad överavkastning genom utgivna aktieindexobligationer. Detta kommer att undersökas genom att räkna ut Sharpe kvoten för respektive aktieindexobligation och jämföra den mot den underliggande tillgångens Sharpe kvot. Undersökningsdata är beräknade på månadsbasis och sträcker sig över drygt tio år för att fånga produkten i upp samt nedgångar på börsen. Vi har med hjälp av vedertagna ekonomiska jämförelsemått undersökt om det går att påvisa någon skillnad i Sharpe kvot för aktieindexobligationerna och dess underliggande tillgång. Resultaten av studien visar att Föreningssparbanken inte lyckats generera en högre riskjusterad avkastning än de underliggande tillgångarna.

Genomisk selektion inom köttraser

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.

Självmord : en forskningsöversikt

Suicide is the ultimate outcome of mental illness and is a big and serious problem in society. About 1500 persons commit every year suicide in Sweden and many more engage in suicidal behaviour. This review aims at, from research studies from the 21th century, find out the knowledge of riskfactors regarding the risk for committing suicide among adolescents. The research questions are: What does research say, from a psychobiological perspective, about riskfactors among adolescents regarding the risk for suicidal behaviour? How much does genetic factors have an effect on the risk for suicidal behaviour among adolescents? and : What is the importance of environmental factors such as family connections, friends and school environment concerning suicidal thoughts among adolescents?The method that is used in order to answer these questions is a researchreview including ten research-studies.

TOC and TQM Utilized in a Mass Customization Production Environment

Background: Mass customization has been identified as a competitive business strategy by both companies and academics because of its ability to incorporate the voice of the customer into companies? products and services. Although mass customization may sound appealing, the strategic concept is still developing and firms adopting this business strategy face several challenges. Production concerns are of high relevance since mass customization implies a high level of customer involvement in the product design. Since the areas are closely linked it is reasonable to ask how a mass customization strategy affects production concerns.

Phenotyping of Bali cattle and interviewing farmers in Indonesia - a minor field study

Among the Indigenous cattle breeds in Indonesia, the Bali cattle is the most preferred by small farmers. The Bali cattle is a beef breed, and is considered to have several advantageous characteristics and to be well adapted to the country?s harsh environmental tropical conditions with drought and rain. The main aim of this project was to phenotype of Bali cattle from different locations in order to identify and document diversity within the Bali cattle breed based on their observable characteristics, to compare cattle from different areas and production systems to see the effect of management on phenotype. In this study, 107 cows and bulls of the breed Bali cattle, from Kalimantan, Sumatra, Lombok and Bali were phenotyped.

Patienters livssituation och vårdkostnad

The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available variable Health Care Cost (in Swedish VK). In that case the searching for connections between VK of patient groups and the result of health care efforts would be sufficient to gain knowledge of possible connection between health care efforts and life situations. Thus that is the final purpose.

Genetisk variation i brunststyrka hos svenska mjölkkor :

When cows in Sweden are inseminated the heat strength is reported to the Swedish milk-recording scheme and AI scheme. Cows that show strong signs of estrus are desirable and the trait is included in the Swedish breeding goal. A strong heat makes it easier to inseminate at the right time and to avoid long and expensive days open. Since ten years the heat strength is scored from one to five by the farmer and reported to the milk-recording scheme and AI scheme. Earlier the score was from one to three and the decision was made by the AI technician.
