Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Yrket personbilsmekaniker har genomgått en stor förändring. Idag ställs det helt andra krav på mekanikern än det gjordes för några år sedan. Både miljökrav och ökande bränslepriser har gjort att biltillverkarna tvingats att göra bilarna mer bränslesnåla och mer snälla mot miljön. Detta har gjort att bilarna idag är mer tekniskt avancerade än förut, och därför alltmer svåra att serva och reparera. Det ställs därför helt andra krav på mekanikern nu.

The purpose of this essay has been to answer the question of whether or not administrators of economic support perceive that their professional status is ranked lower than that of their coworkers in other fields of the social services. We set out to study whether or not their comparative status differed depending on their use of standardized assessment instruments and if their experience with regards to professional status differed depending on the size of the municipality they worked in. We also wanted to determine in what way (if any) the comparative status manifests itself and what factors influences it.We?ve utilized method triangulation in order to answer the questions posed in our purpose. The quantitative study was conducted using a questionnaire and the qualitative with three interviews.

En undersökning om det åländska sjömanslivet.Syftet med detta arbete vara upptäcka hur livet var på sjön på de åländska fartygen under mellan åren 1900- 1945. Det andra syftet var att utifrån hieratiska sjömanslivet få fram vad som gav status på de åländska fartygen.  Resultatet visar att för att få de åländska fartygen gällde det att individen skulle uppfylla sjömansidealet. Sjömansidealet var bland annat att sjömannen skulle vara modig, fysisk stark och ha erfarenhet. Status kunde sjömannen få inom två kategorier, inom arbetet och inom det sociala. De faktorer som gav status inom arbetet var att arbetsam, kunnig, fysiskt stark, modig, beslutsam, erfaren, hård.

Introduktion: Arbetsrelaterad stress är idag ett växande problem och det har visat sig att det är många olika faktorer som orsakar stress. Det har också visat sig att stress ligger till grund för tillstånd av ohälsa, bland annat hjärt- och kärlsjukdomar. Även socioekonomisk status är något som sammankopplas med både stress och hjärt- och kärlsjukdomar. Eftersom befintlig forskning är något begränsad gällande huruvida arbetsrelaterad stress, socioekonomisk status och hjärt- och kärlsjukdomar samvarierar var det av intresse att undersöka detta. Syfte: Syftet med denna studie var att beskriva upplevelsen av arbetsrelaterad stress i relation till socioekonomisk status och hjärt- och kärlsjukdomar.

There are no guidelines regarding how companies should design status updates on Facebook which attain good readability and engage the readers. Half the Swedish population are Facebook-users, but companies have yet to publish comprehensible messages on Facebook which effectively include the recipients. Inclusion is not just a matter of accessibility, but also of readability.Therefore, I studied how status updates should be designed on Facebook in order to increase the readability and to engage the readers. My target group is 22-32 year olds, since the company I worked with wanted to target this group. I conducted my research through literature studies, interviews with the client, analysis of past status updates, questioned an expert in social media, and organized a group interview with the target group.My research shows that status updates should contain information that is topical, informative and relevant to the target group.

Syftet är att undersöka vilka föreställningar föräldrar och förskollärare på en förskola i Sverige har om förskolläraryrkets status och vilka föreställningar de tror folk i allmänhet har. Syftet är även att undersöka föräldrars syn på förskolans uppdrag, om deras inflytande påverkar förskolans status och om förskollärarna i studien känner en yrkesstolthet. Frågeställningen i studien är: Hur beskriver sex förskollärare och 34 föräldrar sin syn på förskolläraryrkets status? Studien genomfördes med både kvalitativ och kvantitativ metod i form av enkäter och intervjuer, för att ge studien både bredd och djup. De slutsatser som kan dras utifrån studien är att en majoritet av föräldrarna anser att förskolläraryrkets status är låg och att en majoritet av förskollärarna inte är nöjda med sitt yrkes status.

Several reports and scientific research have shown that unemployment affectshealth negatively and that it is the young unemployed who suffer the most. Despitethis, there were not many evaluated labour market programs for young peoplefocusing both on how the labour market programs affect the job status and health,most of them were only focused on job status. Since there were not manycompilations in that direction, the essay is intended to describe the variousprograms and their impact on both job status and health. A literature-based studyhas been conducted and 15 articles have been reviewed and compiled into variouscategories using a content analysis. It turned out that the majority of the mostcommon labour market programs were represented in the scientific literature.There was also a new genre that is not mentioned in previous reports, cognitivebehavioral therapy (CBT), which proved to be one of the most successful programs.Michigan Prevention Research Center (MPRC) job search programs also showedsome positive results.

Syftet med undersökningen är att diskutera synen på läraryrkets status, genom att ta reda på vilka faktorer som kan påverka ett yrkes status. För att kunna analysera den empiri som samlades in kommer Gunnel Colnerud och Kjell Granströms teorier om ett professionellt yrke att diskuteras. Ulfsdotter Erikssons avhandlig om bland annat yrkesstatus och Gerhard Arfwedsons teorier om lärarlöner och kvinnodominans inom läraryrket kommer också att behandlas. Andy Hargreaves teorier används för att diskutera de statusskillnader som redan i skolan präglar eleverna och de fungerar även som ett komplement till Arfwedsons teorier. Undersökningen genomfördes med hjälp av en kvantitativ metod, i form av enkäter.

A lot of habitats have declined or disappeared as the old cultural landscape changed to the modern agricultural landscape of today. Places such as power line corridors, racing tracks, gravel pits and military training sites have become refuges for many species associated with the old cultural landscape. These sites have been exposed to ecological disturbances that create the same type of habitats that were found in the old cultural landscape.The military training sites in Sweden has an impressive diversity of species. Disturbances from the military exercises have created habitats that are important for a wide range of species.The purpose of this thesis is to study some of the ecological disturbances occurring in the military training sites of the Swedish Armed Forces and examine how they affect different types of habitats. The thesis explains through litterateur and field studies the reason to the rich biodiversity often found at military training sites.

This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

This project aims to explore how to create a working concept-based flower shop visual identity, with focus on brandig, eco-branding and visual communication. My main question is: How do I create effective visual communication for an ecological flower shop? The results of this thesis are that there are things to consider when creating a visual identity with an ecological concept. The most important question is if there is any benefit for your company to go green, otherwise positioning of your company will be hard. What I realized during the design part of my project was that if I use the methods described in this thesis and consequently applying my choices after the flower shops identifying words, a working concept-based visual identity will be possible to create..

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen. There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice. My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.
