Föräldraledighet som en kompetensutvecklande period i livet

The aim of the study was to examine whether parental leave can serve as capacitating period in life. More specifically our aim was to get a deeper comprehension of the abilities and competencies developed through parental leave and how these can be of use to the individual when at work. 12 semistructured interviews were conducted with employees from a large organization in the south of Sweden. The results were analyzed using a hermeneutic approach. The results of the study show that competencies and abilities such as effectiveness, organizing, multitasking, leader abilities, communication, sensitivity, limiting skills, mindfulness, acceptance, self-confidence and life balance were enhanced during parental leave.

Påverkas hästens hudtemperatur av magnettäcken?

The market offers more and more products that are claimed to have medicallypositive effects (like increased blood perfusion etc.) due to their magneticproperties. The objective of this study was to investigate if blankets containingpermanent (static) magnets have a greater impact on cutaneous blood circulationthan ordinary blankets without magnets. Eight standard bred horses were used in across-over study. The cutaneous temperature was presumed to reflect blood flowin the skin and therefore thermography and local thermistors were used to indicatechanges in circulation. Baseline values were registered before the blanket wasapplied.

Dragare, täckningsgrader och önskelådor : systematisering och råd för grönplanearbete

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

Förskollärares kunskap om stress och stresshantering bland barnen på förskolan

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

Landskapsplan för Tosthult : en småskalig studie och skötselplan

The aim of this dissertation is the production of a landscape management document to protect and improve elements of biological, cultural and economic value found within the site at Tosthult. The study involves both analysis of the current grazing regime, comparison of today?s flora with flora collected in the fifties and a SWOT analysis of inhabitants? views on Tosthult?s landscape and neighbourhood. The resultant landscape management document applies to an area over 134 ha and is valid for thirty years. The proposal contains 26 separate management units, each with necessary information on the area, definition of management goals and the mix of management procedures to undertake.

Implementeringen av IAS 19 - En studie av borttagandet av korridormetoden och dess implementering av nya IAS 19 samt dess påverkan på ekonomistyrningen

Abstract: Since the implementation of IFRS, many changes in accounting standards have occured. Companies that follow IFRS must therefore always adapt and change its accountingprinciples according to changes made by IFRS. The latest change that companies must consider and adapt to in their financial accounting is the revised version of IAS 19 regarding pensions. This study aims to investigate if there is a relationship between financial accounting and management accounting due to changes made by IASB. More specifically the study investgates how the removal of the corridormethod and the introduction of IAS 19 as an external approach has affected its management accounting in three large corporations in Sweden.

Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.

Simulering av översvämningar i Nedre Dalälven

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Förpackning med förbättrad miljö- och säljaspekt : Ett projekt i samarbete med Primus Sverige AB

This work of examination describes an environmentally oriented product development aimed to develop new packaging with improved environmental and sale aspects of the products from Primus Sweden AB. The report covers the design process from the first collection of facts to the final results with a description of all methods involved in the work. The focus has been on a clear environmental awareness and the report contains a deepening of the concept life cycle assessment (LCA) for product development. In the process, the consumers? opinions of the brand Primus and environmental profiling formed the basis for the packaging to communicate the right values such as quality, technology, environmental awareness and adventurer?s first choice.The deepening of the life cycle analysis shows that composting and other alternative treatment of the biological cycle is not possible to implement in a satisfactory way in the design process.The work results in two final concepts.

Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)

Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

Shys metod för att mäta byteskostnader - en kritisk granskning

This thesis? objective is to evaluate the recently proposed Shy (2002) approach of estimating consumer switching costs. We apply Shy?s method for estimating switching costs on the Swedish markets for bank deposits and telecommunications. The evaluation has been achieved by comparing estimated results to economic theories, related empirical studies, and our expectations.
