Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

AbstractPurpose/Aim: The aim of this essay is to examine the democratic potential of Forum Games.The main focus of the essay is if working with forum games can help the participators to better communicate their thoughts and ideas and through this take better part in a democratic society.Material/Method: The material to the study has been gathered through three interviews with persons using forum games in their work and one enquiry with 21 students in Teacher education at Uppsala University, who had recently tried the method for the first time.Main results: The conclusion of the study is that forum game has a democratic potential. Ability to communicate is important for a democratic society and participating in forum games can improve the participators communication abilities. Furthermore forum games seem to have other positive effects on a democratic society, apart from helping the participators to improve their communication skills.Keywords: Forum Games, Forum Theatre, Communication, Democracy, Drama.

We live in a world where the resources are not equally divided and that is why charity work is needed. The United Nations Children?s Fund, UNICEF, is a global organization that works for children?s human rights around the world. But perhaps even charity work, which´s often glorified in the society, need to be looked at from different directions. Research about intercultural education, globalization and charity shows that even good deeds can end up reproducing the problem that was supposed to be solved in the first place.

Background: Thanks to the globalization and the EU the international trade is growing faster than ever and companies are able to change ownership across the borders of the nations. Today one can talk about global marketplace with a deeper integration of the economies of the world. The rapidly growing list of mergers of Swedish companies since the last 10 years indicates that the global companies of today is using mergers as a strategic tool for continue their growth. However the number of unsuccessful mergers is big. The need of understanding and knowledge about different cultures is growing in the global business climate of today, since the collaborations across de national borders are increasing.Problem formulation: Which international strategies are fortunate in international mergers with Swedish companies?Purpose: The purpose is to analyze the integration of the three mergers; Vin&Sprit ? Pernod Ricard, Astra - Zeneca and Telia ? Sonera.Method: This study is a case study with a qualitative approach.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Problem discussion: Syncron experience a challenge in realizing the full market potential of its newly developed IT-based price management system, Global Price Management (GPM). The system has already been implemented and is currently running with success within the IT-structures of the first customer. The fact that the development of the system has been initiated by a customer, and thereby has left Syncron oblivious of the real underlying drivers and incentives for the development, is part of the problem. Understanding the customers? incentives for developing their pricing process thus reducing the application uncertainty is a good starting point.

Arbetstagarnas motivation har blivit allt viktigare för företagens produktivitet och effektivitet. Många menar att en motiverad personal gör en bättre prestation vilket leder till att företagen får en ökad produktivitet. Syftet med detta arbete var att undersöka hur arbetsuppgiften påverkar de anställdas motivation och prestation, och följande frågeställningar ställdes: Blir arbetsprestationen bättre när arbetets motiverande potential är högre? Blir den inre arbetsmotivationen högre när arbetets motiverande potential är högre? Blir arbetsprestationen bättre när den inre arbetsmotivationen är högre? Vilket av fem karaktärsdrag är minst representerad? Vilka skillnader finns mellan de anställdas motiverande potential?Hackman och Oldhams (1980) teori utgår från vilka karaktärsdrag en arbetsuppgift innehåller. Karaktärsdragen är variation av färdigheter, uppgiftens identitet, uppgiftens betydelse, autonomi och feedback från arbetet.

Studier har visat att sjuksköterskors arbetsmiljö kan påverka dem i deras omvårdnadsarbete. Studien ämnade intervjua sjuksköterskor om hur de upplevde att deras arbetsmiljö påverkade deras omvårdnadsarbete. Intervjuer genomfördes med sju sjuksköterskor på ett sjukhus i Västsverige. Intervjuerna analyserades och manifesta meningsenheter, kopplade till studiens syfte, identifierades och kondenserades. Resultatet visade att det finns flera faktorer i sjuksköterskornas arbetsmiljö som de upplever påverkar dem i deras omvårdnadsarbete.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

I denna uppsats redovisas en jämförelse av den skriftliga delen mellan tio godkända uppsatser från nationella provet i Svenska som andraspråk B och tio godkända uppsatser från Test i svenska för universitets- och högskolestudier (Tisus). I uppsatsen görs först en analys av två syntaktiska konstruktioner, därefter en undersökning av förekommande bisatstyper och till sist en global bedömning av texternas funktionalitet. Analyserna visar att majoriteten av testtagarna har god behärskning av syntaktiska strukturer i svenskan. Skillnaderna som förekommer, på en syntaktisk nivå, mellan uppsatserna handlar om individuella informanters brister och några generella slutsatser kan inte dras. Däremot finns större skillnader gällande den globala bedömningen.

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

This Master thesis was written in collaboration with the Kalmar-based consulting company Sederkvist Kommunikation. The purpose was to explore the market potential for Sederkvist Kommunikations new software Bellman Marketing. Based on these results a launch plan was created and advoice were given to Sederkvist Kommunikation as to how their new administrative tool could be introduced on the market. Data were collected through semi-structured telephone interviews. The population was Swedish so called Gazelle-companies (growth-companies listed yearly by the business newspaper Dagens Industri) and totally 27 units were examined.

Mammary tumors are the most frequent type of tumors in bitches in Sweden. Many studies have been published concerning mammary tumors, but there is still much to be learned about this disease. One has, since some time ago, had the knowledge that addition to or removal of methyl groups to genes can inhibit or activate gene-expression. Methylation and demethylation is a normal phenomenon in the body and it is essential for the development and survival of the individual. The risk of developing a tumor disease is increased if the global methylationstatus is changed; if oncogenes demethylates (activates) or if tumor suppressor genes methylates (inactivates). In the human medicine one has seen that there are differences in methylationstatus between different tumors. In this study tumor and normal tissue from ten dogs were examined with regard to methylationstatus.

Denna studie undersöker vilken potential det Balanserade Styrkortet har att förbättra kommunikationen mellan olika domäner inom sjukvården. Vår utgångspunkt är Kouzes & Micos teori som beskriver sjukvårdsorganisationen som svårstyrd och uppsplittrad i tre domäner: en professionell, en administrativ och en politisk. Det huvudsakliga materialet består av sex kvalitativa samtalsintervjuer. Fyra vid Paramedicinska avdelningen på Ljungby Lasarett och två i ledningen för Landstinget Kronoberg.Vårt resultat pekar på att det Balanserade Styrkortet har en potential att öka informations- och kunskapsspridningen mellan olika nivåer i sjukhusorganisationen, förbättra helhetssynen samt förbättra dialogen kring vision, strategi och mål. För att potentialen ska kunna realiseras krävs emellertid ett ihållande engagemang och kunskap om det Balanserade Styrkortet.
