Psykologiska mekanismer och miljöperspektivet - sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan
Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar
sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos
individer i konsumtionssamhället. Hypotesen var att det finns ett
miljömedvetande hos människan, men att det är en skillnad mellan attityd och
beteendeintention.
Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa
studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom
utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49).
Svarsprocenten var 46 procent. Huvudresultatet visar att det finns en oro hos
individer inför miljön och framtiden och 94 procent av deltagarna anser att
miljöfrågor är viktiga.
A comparison of methods to assess site index in young Norway spruce stands
This study investigates whether the site index curve method (SICM) and the growth intercept method (GIM) can be used for site index predictions in younger Norway spruce (Picea abies (L.) Karst.) stands than recommended by current guidelines. For SICM it was thus investigated whether the method could be used for stands younger than ten years, and for GIM it was tested whether a starting point for the intercept measurements could be used below the recommended
2.5 meter. This was tested based on measurements taken from experimental stands in Tönnersjöheden Research Forest.
For GIM it was found that the method can only be used when the TH-trees of a stand have five complete intercepts above 2.5 meters. For the method to be applicable beyond this, it will be necessary to adapt the underlying equations, perhaps following the Canadian example where a 1.3 meter intercept start is used. In conclusion it is not currently possible to apply the approach beyond the current recommendations.
For SICM, SI predictions are accurate for the study area already form year three.
Förändring av grönområden i Västerås tätort det senaste seklet : Konsekvenser av att grönområden förändras
This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.
Hållbar utveckling i kommunalt beslutsfattande : En studie om integrering och prioritering ur fritidspolitiskt perspektiv
The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.
Insatsens akustik och dess påverkan på hörapparatens förstärkning
The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Miljömärkningar och medvetenhet : En studie om unga vuxnas medvetenhet kring miljömärkningar
Dagens samhälle är präglat av materialism och dagens konsumtionsmönster är ohållbara ur miljömässig synpunkt. Konsumtionen skapar därmed miljöproblem och ett viktigt styrmedel för att göra den mer hållbar är miljömärkning. Miljömärkta produkter produceras på ett miljöansvarigt sätt utan kemiska bekämpningsmedel och gödsel som är skadliga för både människa och miljö. Syftet med denna studie var att undersöka den nuvarande medvetenheten kring miljömärkningar hos unga vuxna på Möckelngymnasiet. Metoden för studien var enkätutdelning till skolklasser som går sista året på gymnasiet.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Samband mellan anknytning och självkänsla hos ungdomar. En pilotstudie
Background:When the patient is critically ill the family is in a vulnerable position. The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Hållbar utveckling: Hjärtefråga eller nödvändigt ont? ? Miljöarbete hossvenska SME-företag i konfektionsbranschen.
The aim of this thesis is to give an insight to how work is being pursued within Swedish SMEin the clothing industry. Furthermore we investigate how efforts can proceed withenvironmental questions in a quest for sustainable development and bring clarity in thedifficulties that occur. Through the use of company examples and a description of how theywork we wanted to give stakeholders knowledge in what resources and procedures that areused today on the market. The function of the report is moreover to provide Swedish smalland medium-sized clothing enterprises suggestions and directions of how to advance withinsustainable development.In our theoretical frame we have chosen to administer the theories that we found suitable forour study. Seen from a perspective of sustainability we have thus applied the theories ofstakeholder and legitimacy, an analysis model for a company?s actions in environmentalquestions and the theory of SME which describes a small or middle sized enterprise?s fivecompetitive variables.The empirical frame we acquired for this thesis is presented in three chapters.
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
En strategisk planeringsmodell: Att införa medborgarkontor i ett folkbibliotek med hjälp av strategisk planering
This Masters thesis is concerned with the complex planning process of setting up a citizen bureau in a public library. The aim is to find out how citizen bureaux are designed and to suggest a simplified model of strategic planning. The planning process is studied from a business perspective in the library context, and this perspective is also used to study citizen bureaux and their written plans elsewhere. A combination of qualitative methods are used: observations, focus group discussions and interviews. Observations in the public library showed a great need for an environmental analysis as well as structure to the planning process.
