Religiös coping i tolvstegsprogrammet : En studie av tolvstegsprogrammets funktion för icke-missbrukare

The purpose with this study is to examine how the twelve-step program is described by the author J Keith Miller (2004) in his book Steg in i livet and by the author Olle Carlsson (2012) in his book 12steg för hopplösa. The aim for the study is to highlight the twelve steps usage on people without addiction problems. In the study, the two author?s thoughts and experience of the twelve-step program is analysed and interpreted by Pargaments (1997) theory of religious coping. The research questions in this study are: 1.

Vilken effekt har lärkrutor på ogräsfloran vid ekologisk höstveteodling? :

This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping. Studies in England have shown that skylark reproduction can be greatly improved within conventional fields, at a low cost, by establishing patches of bare ground (skylark plots). Within conventional farming, herbicides can be used in case a weed problem arises due to implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers. The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.

Konsolidering av v?vsp?nda papperstapeter: analys och metodutveckling

Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps. This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.

Sverige och Art- och Habitatdirektivet - i samförstånd eller avvikande : En studie om reglerande dokuments roll i implementeringsprocessen

Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.

Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Vad styr sortimentet hos svenska perennaodlare? : en studie baserad på sju företag i Sydsverige

The purpose of this study is to clarify the most important factors that affect Swedish perennial growers when designing their assortment. The study describes how herbaceous perennials are produced in Sweden today and try to give an answer to the question how growing method and choice of assortment are affecting the possibilities of Swedish producers to compete on the market. Seven perennial growers in the southern and western parts of Sweden have been interviewed about their production methods and on what basis they design the assortment of perennials. During the interviews five factors seem to be the most important when the growers choose which species to grow ? profitability, the characteristics of the species, the sales channel/customer, the growing environment/growing facility and the grower?s interest and knowledge. It is often a combination of these five factors deciding if a cultivar will be grown or not. .

Indirekta effekter på marklavars abundans och diversitet vid ökad kvävehalt i marken : en jämförelse mellan opåverkad och lågintensivt brukad mark

Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems. We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.

Bevarande av naturvärdesträd i enlighet med FSC och Holmen Skogs naturvårdspolicy :

In the end of 1998 the company Holmen Skog AB was certified accordint to the FSC system with an area of 1 036 000 hectare. After that Holmen Skog AB has been working actively with the nature conservation in the forestry. In order to control the quality of the company?s nature conservation in final fellings they started a yearly inventory which is called BAKRUS (Judgement of ecological and culture care in relations to policies for a persevering silviculture). After 1999 the control was expended to include all actions in the forest.

Thuja plicata - etableringsförsök av jättetuja med fyra olika provenienser

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Kommunala bolag och demokratin - Om bolagiseringstrendens inverkan på folkstyret.

Kulturvårdscentrum was a project that had great significance for local folklore societies in Bohuslän.Bohusläns museum was i charge of the project that lasted from 1987 until about 2001 when most ofthe original staff have retired. The staff was mainly recruited from a large shipyard, Uddevallavarvet,at it's closure due to recession. Financing was largely made by the government to help outthose unemployed who otherwise should have a hard time finding a new job. At start there was about25 employees who where trained for one year by staff from Swedish museums, conservation studios,and teachers the university. The education was aimed at serving local folklore societies, and dealingwith their special problems.

Fågelskådare och lantbrukare i samarbete : kommunikation och naturvård i jordbrukslandskapet

In the spring of 2006 a pilot project was initiated by The Rural Economy and Agricultural Societies of Sweden together with The Swedish Ornithological Society in order to increase collaboration between bird watchers and farmers. The project as a whole comprised 11 farms in South-Central Sweden. The aim was to benefit the decreasing populations of bird species related to the agricultural landscape. The purpose of this master thesis was to study how similarities and differences between bird watchers and farmers regarding opinions about nature, landscape, agriculture, birds and nature conservation have influenced the collaboration. Four of the farmers and five of the bird watchers that participated in the project were included in this study.

Materians och energins bevarande : En studie av gymnasieelevers uppfattningar

Syftet med denna studie är att undersöka elevernas uppfattningar om materians uppbyggnad och om materians och energins bevarande. Den föreliggande studien baseras på en kvantitativ analys i form av en elektronisk enkät, som föregicks av en kvalitativ analys i form av, strukturerade intervjuer och demonstrationer.Eleverna har kunskap om vardagsnära exempel, som till exempel vad en stekpanna är uppbyggd av. De ansåg att dessa är exempel på materia men när det gäller mer abstrakta begrepp som ljus, magnetfält, skugga, vakuum, värme och ljud uppvisar eleverna mer osäkerhet och brist på kunskaper. Hälften av eleverna svarade att luft är materia, vilket tyder på ?gasblindhet? hos de övriga.
