Arvets betydelse för mjölkkors beteende :

It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.

Mjölkraskvigors tillväxt på naturbete :

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Subventioner och hyresrätter? En bostadspolitisk studie

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.

Ska man tro på aktie-Nostradamus? : en studie om aktierekommendationers värde för privata investerare

Intro: 80 percent of the Swedish population own shares. This makes Sweden the leading country in private investment in securities. It can be difficult for the private investor to know where, when and which security to invest in. The strategies are as ambivalent as the stock markets fluctuations. If the investor prefers to refrain from investing money himself, there are brokers who carry out these types of services.

Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun

Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited. The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.

Datorns betydelse för personer med lindrig utvecklingsstörning. : En studie om datorns roll för individers självkänsla inom skolformen Särvux.

Today the ability to swim is taken for granted by most people. Most of Sweden?s adult population can swim which is reflected in the reduced number of accidental drownings. About 1900 AD when Sweden?s population was about five million the average drownings per year was 1100.

Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Jämförelse mellan sådd och naturlig föryngring av tall i Härjedalen

The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

Smärtlindring hos kalv efter avhorning. En beteendestudie där effekten av meloxikam som postoperativ analgesi utvärderas :

In this study, 29 calves were dehorned by heat cauterisation at the age of 1 to 8 weeks. Before the procedure, the calves were given local anaesthetic but were not sedated. In connection with the dehorning, 14 calves were given the non-steroidal anti-inflammatory drug (NSAID) meloxicam and 15 calves were given placebo. During the following three days behavioural studies were performed to investigate if the different treatments had any effect on the calves´ postoperative behaviour. Head shakes, head rubs, kicks and ear flicks were studied, as earlier studies have shown that an increase in these behavioural patterns suggests postoperative pain.

Den sociala rörligheten bland frälse- respektive skattebönder i Björklinge socken 1786?1848

Between 1750 and 1850 the population of Sweden doubled. The increase was very unequally distributed among the different social groups of the rural population. The number of peasants grew very little, while the numbers of the landless (crofters, bordars etc.) more than quadrupled. This study examines whether Christer Winberg's thesis of the landless growth can be applied to Björklinge parish in Uppland. Winberg believes that it was mainly children of tenant farmers who became landless.

?dn?ris?: att b?ja st?nger till t?ltk?ta

This thesis is my exploration of the immaterial heritage that is the craft of bending of ?dn?ris? out of spruce. It?s a broken tradition that is scarcely described, mainly through Yngve Ryd?s report T?ltk?tor (1999) that contains interviews with two knowledge keepers, Nilas Tuolja and Johan Rassa. Yngve Ryd?s report went against the earlier opinion by the mid 20th century ethnologist Ernst Manker who claimed that they were only made exclusively out of mountain birch that has curved growth. As a background, I discuss the special importance of heritage conservation, both material and immaterial, in a S?mi context as being an indigenous people.

Pappersfoton i den digitala eran: Hur företag kan agera vid ett tekniskt skifte

The spread of digital photography has created major changes in the previously stable Swedish photofinishing market. We investigate how companies act to survive in the face of technological change, through our research question: What strategies have actors in the photofinishing business chosen during the changeover from analog to digital photofinishing? Using a deductive method, we have conducted semi-structured interviews with 11 actors in the photofinishing business. Innovation management studies innovation from a number of perspectives, describing effects of innovations on the competitive ability of established actors, and on the value of their resources. The companies were not prepared for the speed of the change.

När förväntad svaghet förvandlas till styrka : En kvantitativ studie om belastande livshändelser och dess utfall

En förutsättning för att undvika depression och istället uppleva posttraumatiskt växande (PTG), efter att ha upplevt belastande livshändelser, kan vara känslan av sammanhang (KASAM). Denna studie syftar till att undersöka om det finns en skillnad mellan belastande livshändelser avseende negativa utfallet depression samt undersöka om en stark KASAM kan vara avgörande för att individen istället utvecklar PTG. I studien undersöks 150 studerande vid Örebro universitet. Av resultatet framgår det att studenterna med högt värde av belastande livshändelser är mer deprimerade än studenterna med lågt värde, oberoende av KASAM. Dock hittades ingen signifikant skillnad mellan belastande livshändelser och KASAM avseende PTG.Huruvida belastande händelser utvecklar en positiv eller negativ förändring hos individen kan istället avgöras av personens tolkning, hantering av situationen..

Metodik för bakteriologisk provtagning från näshålan på får :

Respiratory infections are one of the major causes of disease in sheep throughout the world. In the beginning of 2008 the Swedish National Veterinary Institute and the Swedish Animal Health Service together started a project about respiratory infections in Swedish sheep. This study is an initial part of that project and the aim of this study was to investigate different sampling possibilities with focus on nasal swabs. This study is composed partly of a literature review on causative agents of respiratory infections in sheep and existing sampling methods, and partly of an experimental study comprising 56 sheep. These sheep were sampled with both an ordinary nasal swab and a guarded nasal swab. Before the start of this study there was to our knowledge no described method for sampling sheep with a guarded swab.

Socialisation och livsval : en hermeneutisk, fenomenologisk intervjustudie inriktad på socialisationsprocesser inom jordbruksfamiljen

The aim of this study is to increase the knowledge and understanding of the early process of socialization and its influence on the choices in life, with the example taken from the agricultural family. The question is considering how the process of socialization within an agricultural family has influenced on the choices in life of four women. A qualitative method with a hermeneutic, phenomenologic perspective is applied and four interviews have been done with women who all grew up in an agricultural family. The results have been analysed through social constructive-, psychodynamic-, attachment- and cognitive theory. The results indicate that socialization is a complex process.
