Unesco, Malraux och ombildningens museum : Estetik och kosmopolitik i efterkrigstid

An inquiry into the post-war European aesthetic and political landscape should take the international organization Unesco?s colour reproductions and travelling exhibitions of paintings into consideration. In these, the organization implements André Malraux? idea of the ?imaginary museum? as a framework for a future cosmopolitical, aesthetic (and utopian) community. During the late 1940?s, the Swedish government also discusses the need for raising an ?aesthetic awareness? amongst their citizens as a consequence to a poor knowledge in the fine arts.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Konkurrensrätt : Innebörden av artikel 82 EGF

The competition policy in the EU should guarantee that the competition is not distorted in the way that would prevent or create difficulties for the free mobility of goods and services between Member states. It is prohibited for companies to abuse their dominant position according to Article 82, if it affects trade. The essence of Article 82 is control of market power. The perfect competition results when supply and demand appoint the price and quantity of a product. Firms are encouraged to compete then it results in efficiency, quality products and lower prices.

Några grundskollärares uppfattningar om kulturell mångfald, värden och kunskap tolkade som ideologi

AbstractIn this study, the conceptions of a number of teachers in the Swedish primary and lower-secondary school about cultural pluralism, the values connected to this pluralism by the Curriculum for the Compulsory School System, the Pre-School Class and the Leisure-time Centre, Lpo 94, and the possibilities for pupils to gain knowledge about these values, were studied. The conceptions of the teachers were regarded and interpreted as ideology, since the study was made from a point of departure containing an assumption about how the content of the curriculum is of importance for the development of relations of power and dominance between different groups in society. The purpose of the study was to interpret the statements of a limited number of teachers about cultural pluralism, values and knowledge, regarding the ontological, axiological and epistemological assumptions and conceptions expressed therein. The empirical data of the study was gathered through qualitative interviews with eleven teachers working in six different primary and lower-secondary schools in the Mid-Sweden region. The conceptions expressed in the statements given by the respondents were categorized.

A retrospective study of bitches with pyometra and mucometra medically treated with aglepristone

Pyometra is a common and life threatening disease of intact bitches. The disease is caused by a hormonal influence on the uterus in combination with a bacterial infection. The most common treatment is ovariohysterectomy, but several medical options are available to maintain fertility or avoid surgery and anaesthesia. Drugs that can be used for medical treatment are for example progesterone-receptor antagonists, prostaglandins and dopamine agonist. The present study focused on treatment with the progesterone-receptor antagonistaglepristone in combination with antimicrobial therapy.

Fertility before and after installation of Herd Navigator?

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

Evidens som hegemonisk strategi i socialt arbete : en diskursanalys av den språkliga praktiken i en barn och ungdomsgrupp som arbetar med ett strukturerat beslutsstöd

This thesis describes how social work language practice circulates around the implementation process of an evidence based structured assessment tool – Savry. The purpose is to examine and understand the social workers language practice in a working group that uses this structured assessment tool in their work with youth. The purpose is also to look for dimensions of identity in terms of discourse. The ontological viewpoint is post-structuralism where language is in focus. The theoretical framework is discourse theory based upon the work of Ernesto Laclau and Chantal Mouffe.

Brucellosis in small ruminants : an investigation of knowledge, attitude and practices in peri-urban farming around the region of Dushanbe, Tajikistan

Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

Variation i fruktsamhet hos semingaltar

Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).

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.

Motivation for eating roughage in sows : as an indiction of hunger

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

The welfare of bottlenose dolphins and killer whales in captivity

The aim of this paper was to investigate whether or not it is possible to keep bottlenose dolphins and killer whales in captivity while maintaining good animal welfare. Today, many zoos and aquariums claim that their primary function is to conserve species and educate people about conservation and threatened species. The keeping of wild animals is justified by conservation programs and by the information spread to the zoo visitors. This does however not seem to be the case for marine mammals such as bottlenose dolphins (Tursiops sp.) and killer whales (Oricnus orca) since these species are not threatened in the wild and neither of them are listed as threatened in IUCN's Red List. Bottlenose dolphins and killer whales are entirely aquatic carnivores and are distributed in all coastal and pelagic waters from the Arctic ice in the north to the Antarctic ice in the south.

Reproductive physiology of the female cat

The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

Herrelösa katter i Skåne : problem och hantering

The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.
