Stationsutveckling i stad och på landsbygd : exempel från Gagnef
The intention of this final thesis is to look into the improvement of small and run down railway stations. Many railway stations are today derelict and decaying. The purpose of this essay is to propose alternative strategies of action by discussing the ecology, the history and the social function of the railway station. There is also an overview of projects already completed.
In the analysis part of the thesis, the genius loci or the spirit of place is put forward as means of reaching a solution.
Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern
Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
Hur väl integreras ekobygglösningar hos bostadsbyggande byggherrar
Vi lever idag under ett klimathot som påverkar oss alla. I ljuset av detta har byggbranschen valt att börja ställa om mot en mer hållbar bransch. Under tiden har även ekohus och ekobyar byggts upp som ett alternativ sätt att bo suntSyftet med detta arbete har varit att undersöka vilka val som byggherrar/beställare gör vid projektering av nya bostäder. Jag har valt att inte titta på energianvändningen utan fokuserat på vilka miljömässiga aspekter som återfinns i arbetssätten kring projekteringen av bostadshusFör att ta reda på vilka val som kunde anses som ekologiska/miljömässiga gjordes först en litteraturstudie. Sedan gjordes en enkätundersökning där utvalda företag fick svara på bl.a.
Skolbiblioteket som socialt rum. Om skolbibliotekets placering och utformning.
The aim of this Master's thesis is to explore how the localisation and the design affect the conditions for a school-media centre. A school-media centre is in this study a place where the students seek, find and evaluate information, discuss and exchange ideas. An active place for generating knowledge. The method applied in this study is "Space Syntax Analysis", a quantitative method with visual representation of the results. In the theoretical framework, space is the voids between walls, doors and ceiling, between furniture and bookshelves.
Rällsögårdens missbruksprogram : En studie om klienter och personals erfarenheter av programmet och dess genomförande
The aim is that on the basis of interviews with personnel and clients examine whichexperiences they have of the drug abuse programme and its implementation. To be able toanswer the aim following question has been formulated: (1) What do the personnel and clientthink about the drug abuse program arrangement? (2) In which extend is the programimplemented as thought? (3) How do the personnel assesses the client?s participation? (4)How does the client?s think about their own participation in the program? (5) Do the client?sthink that the program have been helpful in their personal development? A qualitativemethod was chosen and has used a semi structured interview. Total has ten interviews beenimplemented on Rällsögården, five with clients and five with personnel. The study'sinterpretation framework builds on research around drug abuse treatment and theories andmethods that lie to shallow for the drug abuse programme.
Hantering av naturhänsyn efter slutavverkning i Östergötland
Mängden död ved i brukade skogar har minskat med ungefär 90 %jämfört med naturliga skogar. Vid slutavverkning minskar mängden ytterligare. Att lämna naturhänsyn vid avverkning är ett viktigt steg för att bevara biologisk mångfald i skogslandskapet. Denna studie undersöker om naturhänsyn tas bort efter slutavverkning. På 63 % av de inventerade lokalerna hade naturhänsyn tagits bort, mestadels vindfälld tall.
Mikroalger för hållbar energiproduktion - Chlorella vulgaris i en kretsloppsanpassad alg-biogasprocess
Odling av mikroalger för framställning av biogas är ett relativt outforskat område. Den forskning som hittills utförts har påvisat lovande resultat tack vare möjligheten att utnyttja resurser som idag går till spillo, eller till och med utgör miljöproblem; mikroalgerna kan rena både näringsrikt vatten (exv. avloppsvatten) och koldioxidutsläpp (rökgaser från industrin) då de tar upp föreningar innehållande kväve, fosfor och kol från dessa källor. Den producerade biogasen kan ersätta fossila bränslen. Dessutom skapas en rötrest som kan återföras till odlingsmarker vilket sluter näringskretsloppet.
Barn i familjehem: vilka faktorer bidrar till en välfungerande placering?
The purpose of this study has been to investigate which factors are important with foster home placing, to achieve a positive result for the child. The questions that we have focused on is the importance of the child's earlier experiences and relations, the foster homes attitude and approach, the social service organization and the cooperation between these concerned parties. We have also looked at the importance that the relation between the biological family, the child and the foster home can have. This study has been carried out using qualitative interviews with several foster homes, social welfare secretaries and a researcher in the area. We have also chosen to separate the foster homes on the basis of two foster homes only accepting teenagers while other accepting younger children.The theoretical concepts we have chosen to use are connected to attachment theory and the ecology of human development point of view.
"Information-as-thing": Förhållandet mellan biblioteks- & informationsvetenskapen och materialbibliografin
The relation between LIS and physical bibliography is examined primarily through an analysis of such LIS literature as applies physical bibliography in research or otherwise discusses its relevance to information studies. Quite a number of scholars are stressing the usefulness of this bibliographical tradition, even though its position in LIS agenda as a whole seems to be less established. These scholars suggest that physical bibliography presents interesting conceptual and theoretical implications for many of the central objects of study in LIS, for example, knowledge organization, information retrieval, and information seeking. It is also suggested that physical bibliography could help deepen our knowledge and understanding of the digital media ecology. Physical bibliography is foremost seen as a method for the analysis of documents, a method in which not least its terminological apparatus may be a significant tool.
Analys av hemområdesstorlek hos mellansvenska vildsvin (Sus scrofa scrofa)
The wild boar population grows rapidly in number in Sweden, and it has been predicted that the annual number of shot wild boar will soon exceed the cull of moose. According to estimates, the Swedish population encompassed some 150 000 individuals in 2010. The mean annual harvest has increased by 30% since 1990, indicating that the wild boar is a species we must learn to manage sustainably. A successful management of the boars aims for a population in balance with agriculture and traffic, and also provides good hunting opportunities. For this to be possible, understandings of several aspects of the ecology of wild boar is needed.
The sows in this study had an average homerange of 707 hectares during summer, and 659 hectares in winter.
Ekosocial välfärd : En kunskapsöversikt
There seems to be a consensus in the world that the climate is changing, bringing unpredictable and severe consequences for both humans and nature. The feld of social work is known for helping misfortunate individuals and groups, and is said to deal with people in their environments. Yet there seems to be a lack of giving these environments meaning as also something natural. This thesis has the purpose of exploring the connection between social work and the physical environment made by research literature, using the methodology of literature review. The questions asked is in which ways the physical environment can be connected to human welfare; if so, what implications are there for the feld of social work, and fnally how can the discussion be understood using a typology over environmental sustainability presented by Andrew Dobson.
Grön Marknadsföring = En Naturlig Strategi : Analys av Grön Marknadsföring i dagligvaruhandeln
Syfte: Att analysera hur dagligvaruhandeln använder sig av Grön Marknadsföring internt och externt för att positionera sig som ett miljövänligt företag på marknaden.Metod: En deskriptiv undersökning med primärdata i form av personliga intervjuer från de tre största aktörerna inom svenska dagligvaruhandeln.Teori: ?Green Marketing Activities at the Three Levels? har används som modell för att ta reda på hur de olika företagen arbetar med Grön Marknadsföring. Modellen är uppdelad i åtta områden och tre nivåer för Grön Marknadsföring.Slutsats: Samtliga företag vill ta ett miljöansvar, men två av tre ser sig även ha ett ansvar att informera och hjälpa kunder till ett bättre handlande. Två av de tre undersökta företagen är mer inriktade på att bygga ett ekologiskt varumärke medan det tredje företaget är mer inriktad på att upplysa om ekologi. Undersökningen visar dock att alla aktörer har undermåligt arbete med marknadsföringen i butik för att fånga upp kunders ekologiska intresse.
Gestaltningsförslag av gravplatser ur ett miljöperspektiv
Environmental issues and ecology is something that is discussed by the Climate board of the UN and by our Swedish politicians. The first part of the thesis deals with the effects of emissions of greenhouse gases in our atmosphere. There is a discussion about what counts as greenhouse gas. Interviews have been made with two growers of annual plants and one interview with a person who has worked hard to increase the use of perennials in his work place, Mjösund?s cemetery.
Integrerat Performance Management System -En studie om ett ledningssystems påverkan inom Volvo
The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.
Development of green space in Dar es Salaam, Tanzania
In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements.
The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today.
The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.
