Den arktiska isens påverkan på havssaltsaerosoler vid Barrow, Alaska
The global climate change affects the Arctic region the most. The decrease in arcticsea ice is one of the reasons why, it accelerates the warm-up of the region.To understand the changes in the Arctic climate, knowledge about what affects thechanges in the sea ice is necessary. One of these processes could be the relationbetween the extent of the sea ice and the concentration of sea salt aerosols in thearea.This work studies how a variation in the arctic sea ice extent affects theconcentration of sea salt aerosols at Barrow, Alaska. To do this aerosoldata, icedataand winddata has been analyzed over the years 1998-2007. The results shows that aseasonally variation in the sea ice extent affects large aerosols (1-10 ?m) whilesmaller aerosols (<1 ?m) doesn?t seem to be affected as much..
Varför är du så tyst? : En studie byggd på lärarintervjuer om talängslan i skolan
The purpose of this essay was to find the reasons why some students do not dare to participate verbally in the classroom. I also wanted to know how teachers are working to make it easier or students with communication apprehension. After that I put the teacher?s answers in contrast to the theory. I used qualitative interviews as the method.
The Sound of Skepticism Analyzing Climate Change Denial in Swedish Podcasts and YouTube Channels
This study explores Sweden's climate change denial by analyzing the spoken-word discourse of
its countermovement, focusing on digital media content from Swedish parliament member Elsa
Widding with an aim to provide empirical insights into the discourse of Sweden's Climate
Change Countermovement (CCCM). Questions guiding this study are: What are the most
prevalent topics and themes related to climate change denial and skepticism? How do they align
with established categories of climate change denial, shaping the overall narrative? What
mobilizing ideas and meanings are present, how are they shaped, and how do they contribute to
the movement's goals? The material consists of Elsa Widding's complete audio-based
"movement texts'' from 2019-2023, including YouTube content, podcasts, and appearances on
Riks, totaling over 2000 minutes of audio transcribed into text via AI technology.
Methodologically, this study adopts a mixed-method approach which blends computational
pattern detection, topic modeling, clustering, and spatial relationship mapping techniques, along
with qualitative content and framing analysis. Theoretically, the study employs a perspective
which uses epistemic and response skepticism to examine climate change denial, viewing it
through the lens of countermovements and social movement framing. The study's main
contribution lies in the enablement of comprehensive analysis of a large audio-based dataset,
achieved by leveraging recent AI advancements for reliable audio-to-text conversion combined
with topic modeling.
Skiljer sig riskuppfattning och riskhantering mellan kvinnliga och manliga privata skogsägare? : en enkätundersökning bland privata skogsägare i Sverige
As a forest owner you always have to consider hazards and uncertainty when planning your forestry actions. The aim with this report is to test my hypothesis that there is an overall difference between men and women when it comes to perception, estimation and management of hazards/risks in forestry. I will look into if there are differences in how men and women estimate risks in production forestry from an economical point of view. The aim is also to look into if there are differences between male and female private forest owners, in how they perceive and manage hazards in connection with a possible climate change.
To fulfil this aim, an inquiry survey was undertaken in three different areas of Sweden, two areas in the south and one in the north. But in this report I have evaluated the three areas as a whole.
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in Cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Den svenska regeringens förvirrade klimatarbete
The aim of this study is to clarify the Swedish government?s purpose of participating in theEuropean Union Emission Trading Scheme. Taking as its departure point state-centricinternational political economy this study presents three plausible hypotheses on what thepurpose might be. Either it is to promote consumers interests, or to promote the Swedishnational climate goal ?Reduced impact on climate?, or to promote the profit of Swedishcompanies.
Naturgas i Australien år 2020 : Framtida konsumtion, export, import och produktion samt konsumtion under inverkan av ett klimatavtal
Australia is one of the largest producers and consumers of fossil fuels in the world. In a society where the effects of fossil fuels on global warming are constantly discussed, the nation?s production and consumption are subject to debate. Problems arise when negative aspects of consumption, such as emissions of greenhouse gases, are put in relation to an increased need of energy and economic growth. However, it is important to distinguish between different types of fossil fuels when it comes to their individual impact on the environment and to analyze the possibilities to increase the more environmental friendly ones.
Att spela in tramp i studio: En studie om studioinspelning av fotsteg i snö
The complex sound of someone walking in snow aren't easy to create in a studio. The best way to get the sound is to go out on a surface with real snow and record the footsteps there, but it is a complex procedure to get the right sound on the snow because snow sounds different in various temperature and various kinds of snow. It is important to find the right kind of snow to get the right sound on the foot steps. In a studio, the foley artist can create the sound of footsteps in snow by walking on different kind of material, like potato flour, coarse salt or corn flakes, the question is how realistic this materials sounds and what temperature on the snow they sound like. The results shows that the real snow (warm and cold snow) sounds most realistic and the potato flour sounds like warm and wet snow, the corn flakes some think sounds like cold snowwhile others think that it doesn't sound like snow at all and the coarse salt sounds like snow when it is around -10°C in the air, they all sounds similar in realism compared to each other.
Interdependens för Sverige: Hur svenska politiker påverkats av ökad internationell interdependens
This is an examination of how interdependence affects the behaviour of politicians and their ability to govern the way they want to. I analyze the memoirs of two Swedish prime ministers, Tage Erlander and Ingvar Carlsson to explore their experiences. I focus on how the increasing interdependence affects the politicians with regards to security, welfare, and financial policies. Sweden had a special position between Soviet and NATO during the cold war. This meant Sweden gave priority to it's neutrality policy during the cold war, compared to increased trade cooperation.
EU:s normativa makt inom miljöområdet : En fallstudie om EU:s roll i det globala klimatarbetet
Over the past twenty years, the cooperation within the European Union (EU) has strengthened and expanded with both more number of Member States and stronger influence on international politics. The unique character of the Union and its ability to enforce peace and humanitarian intervention has attracted attention in political science. This prominent position of the Union is perceived by many scholars who often hold this derived from the Union's influence in international relations. Various terms have been used to define the powers of the Union. The British researcher Ian Manners states that the unique identity of the Union in the international arena is formed by its normative power. An important policy area within the Union is the environmental cooperation.
Om samspel och gruppklimat i arbetsgruppen : En kvalitativ studie om samspelets och gruppklimatets betydelse för arbetsgruppens gemensamma psykosociala arbetsmiljö
The purpose of this paper is to identify significant factors of influence for the co-existence and team climate within working groups, and to examine their impact on the psychosocial work environment within a group. Team climate and interaction affect every individual in a group. The manager, however, is the one formally accountable for the psychosocial climate in a working group, which is the reason why this study uses the management perspective.As an introduction to the empiric study, an overview of the existing literature within the field was made. A qualitative method is used and the empiric data is based on semi-structured interviews. The study comprises six interviews with department managers within the Social Services in the City Council of Stockholm.
Ekonomi i Passivhus : En studie av två verkliga byggnader
The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.
Modellering av supra och englaciala vattenkroppar detekterade i markradar data från Grönland
Earth science is a dynamic system science that explores the structures and processes of the earth. Knowledge about the earth is important for citizens since the science is a vital part in the sustainable development of the society. Without good basic knowledge the citizens don?t have the possibility to anticipate in the questions and decision-making that concerns e.g. anthropogenic climate change. In the Swedish school system earth science is not an independent subject until academically studies at the University?s.
The impact of climate change on agriculture in the Republic of Mauritius : a socio-econometric study on Mauritian farming
"Food security is a situation that exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life" (FAO Summit, 2003, pp. 28).Food insecurity is of concern regarding the Republic of Mauritius (ROM) since it is defined as a net food importing country. (Farming news, 2008). The impacts of climate change followed by their complexity could potentially have an increased risk effect upon the social and environmental welfare as well as the economic drivers in the ROM (www, UNESCO1, 2009). The primary victims when it comes to the impacts of climate change are the Mauritian agricultural producers since agriculture is highly dependent on climate stability, therefore affecting the yields of the producers.
