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.

Lastbilschaufförers upplevelse av Kör- och vilotidslagen och dess betydelse för individens arbetsförhållande

Tidigare forskning om lastbilschaufförers arbetsförhållanden har visat att de utsätts för ett flertal stressorer i arbetet och att de har låg kontroll över sitt arbete. Syftet med studien var att undersöka lastbilschaufförers upplevelse av stress till följd av Europeiska Kör- och vilotidslagen (KoV), hur de upplever sin arbetssituation samt bidra till att öka förståelsen kring lastbilschaufförers arbetsförhållande. Studien omfattade sex manliga lastbilschaufförer från Trestadsregionen (Uddevalla, Trollhättan, Vänersborg) som omfattades av KoV. Samtliga chaufförer hade familj med olika ålder på barn och chaufförernas yrkeserfarenhet varierade mellan 19 och 40 år. Det genomfördes en kvalitativ studie utifrån en tematisk analysmetod.

Dubbelprövningsförbudet avseende skattetillägg och skattebrott : - en utredning av införandet av regeringens förslag gällande en spärreglering samt ett samlat sanktionsförfarande ur ett rättssäkerhetsperspektiv

A tax penalty is an administrative penalty and is levied when the tax obligated provides false information for the guidance of their own taxation. Further can the taxpayer also be punished for tax evasion for the same false reporting. However, this is contrary to the European Convention that we should not be tried or punished twice for the same crime. The Supreme Court has through practice from 2013 ruled that the right not to be punished twice for the same offense shall include the system in force concerning tax and tax offenses. The Supreme Court has by this judgment determined that the system of penalty and tax evasion is not compatible with the dual test ban.In the light of the judgment the Government submitted in November 2014 a draft to the council regarding double test ban regarding penalty and tax evasion.

Business Process Outsourcing : En studie av företag i Jämtlands län

Previous research has, by studying large listed firms, identified cost reductions and knowledge transference as the primary reasons for outsourcing.  Previous research has also indicated that Business Process Outsourcing is likely to increase in popularity and experience high annual growth going forward. This study aims to explore why mid-sized and large firms decide to in Jämtlands län, fully or partly, outsource their finance/accounting activities. Theories regarding transaction cost economics and resource based view composes the foundation of this study and the information used has been gathered through the use of semi-structured interviews.  The results shows, like the chosen theories and previous research indicates, that the outsourcing decision is primary based on expected cost reductions.

Kramfors och kampen om livskvaliteten - En diskursanalytisk studie av kommunens marknadsföring

In the era of urbanization and globalization, many small, rural and post-industrialcities struggle for growth. The competition for citizens and visitors is intense, andone commonly used strategy is to promote the city to a target audience. Placemarketing, however, is homogenized to a great extent. Marketing thus seems likea useless approach, yet almost every city does it.By using discourse analysis and institutional theory, this essay aims to explainwhy the city of Kramfors markets itself. There are several problems arising due tothe marketing of places, especially concerning the discrepancy between the city?simage and identity.
