Subventioner och hyresrätter? En bostadspolitisk studie
Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.
Nyckeln till den positiva spiralen - En studie av musikers syn på sitt övande
Title: The key to the positive spiral - A study of musicians views of their practicing. The purpose with this paper is to make clear how continuous practicing on one element affects not just the specific part but also other things. Is it possible to find a positive spiral where everything can be better if you focus your practicing on one thing? Can this element if it is done daily in a qualitative way transform to a key which will help you to unlock the door to the positive spiral? Are there more keys to find? I am going to reflect my ideas in this paper through a philosophical, psychological and the brain sciences perspective. Quality in action is going to be compared with the quality that you need to set a successful goal, and to reach the state of mind called flow you will need both these qualities.
Snabbt, säkert eller skönt? : Cyklisters preferenser i trafiken
Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.
Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie
Running water-pathways have played an important roll in Sweden and frequently been
manipulated. One profound change was made during the period of logging when
streams were cleared from obstacles as big boulders, sharp bends and side-streams.
Dams and different constructions gave control of the stream water and the streams
became channel-like with a homogen structure. This interference gave problems for
many fish populations and resulted in a shortage of feeding habitat, over-wintering
habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural
temperature fluctuations. Many of these historical changes of the watersheds are now
subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.
Enabling behaviour change : community-based social marketing strategy in Malmö
Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda.
Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.
Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation
South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.
Insatser och åtgärder för främjandet av laddelbilar i Sverige
To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society.
The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.
Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel
Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management.
The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.
Bredband och Internet i Sverige : en kartläggning av faktisk tillgång och användning ur ett ekonomiskt perspektiv
Globalt sett är Sverige ett föregångsland inom informationsteknologi. Såväl nationell som internationell statistik visar på växande bredbandstillgång och alltmer frekvent användning av tjänster på Internet. Sådana siffror utgår emellertid ofta från ett leverantörsperspektiv och teoretiska prestanda. Detta examensarbete kartlägger faktisk tillgång till bredband i Sverige, samt utvärderar dess implikationer för fortsatt utveckling av Internetanvändningen ur ett ekonomiskt perspektiv. Dessutom analyseras framtidspotentialen för nuvarande accesstekniker i landet.Datastudien innefattar de trådbundna accessteknikerna xDSL, kabel-tv och fiber-LAN samt ett antal trådlösa tekniker, så kallat mobilt bredband.
Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE
The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.

Riskhantering i infrastrukturprojektet Varbergstunneln
Syfte: Syftet är att beskriva och analysera riskhantering av projektrisker och finansiella risker i infrastrukturprojektet Varbergstunneln under planeringsfasen där två aktörer har studerats, Trafikverket och Varbergs kommunala verksamhet, och deras perspektiv på riskhantering och hur dessa aktörers perspektiv skiljer sig åt för att få förståelse för hur olika typer av risker och aktörer riskhanterar utifrån deras perspektiv i ett infrastrukturprojekt.Bakgrund och problem: Trafikverkets uppgift är att se till att tågen kommer i tid, transporter sker så säkert som möjligt och med minsta möjliga miljöpåverkan. Tillsammans med andra aktörer ska de se till att den bästa möjliga samhällsnyttan skapas för pengarna. Den 21 mars 2013 kom regeringens tillåtlighetsbeslut för delprojektet genom Varberg för att bygga ut järnvägen från enkelspårig till dubbelspårig. Detta är en av de största utmaningarna i Varbergs kommun där den kommunala och den statliga planeringen måste gå hand i hand. Det finns stora risker kopplat till infrastrukturprojekt men det finns också stor möjlighet till samhällsekonomisk lönsamhet.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun
Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited.
The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.
