Changing climate affects various ecosystem processes within the boreal forest, wildfire among them. Meanwhile temperature is commonly accepted as one of the most important regulating factors. In the context of 2016 being the warmest year in observational history, this review attempts to identify changes in wildfire extent within the central and south-eastern Siberian taiga. Satellite based estimat
Reliable information on land cover is required to assist and help in the decision-making process needed to face the environmental challenges society has to deal with due to climate change and other driving forces. Different methods can be used to gather this information but satellite earth observation techniques offer a suitable approach based on the coverage and type of data that are provided. Fe
Abstract Author: Mikaela Persson Title: Who suffers the most from mental health? A quantitative study about mental health among young adults in Italy and Sweden Supervisor: Anna Tegunimataka Assessor: Anders Östnäs The aim of this study was to compare mental health among Sweden’s and Italy’s young adults by using three variables which were then correlated with the variable “mental health”. The
Several problems concern about energy are frequently discussed in recent decades, such as the shortage of traditional energy resource, the increase of energy price and the destruction of living environment by energy conversion. To solve these problems, sustainable development of energy become a preferential task all around the world. Under current circumstances, applying energy saving measures and
Tropical cyclones influence processes within the carbon cycle on different time-scales. Forested ecosystems suffer windfall and long-term impacts from tropical cyclones, leading to the release of CO2 to the atmosphere. The coarse woody debris created by extreme wind speeds and landslides brought on by tropical cyclones can leave a forested ecosystem via riverine channels and end up in the ocean, w
The orbital approximation for stellar streams is the assumption that all stars in a stream can be described as following the same orbit. In this thesis, I evaluate this approximation as a method for constraining the potential of the Milky Way. I wrote a program in MATLAB which integrates the orbits of test particles in a potential model which resembles that of the Milky Way's halo and disc. Th
The aim of this thesis is to gather existing literature regarding the challenges senior human resource managers face in multinational corporations when managing a global workforce, as well as to discover the strategies that are used within the field of international human resource management. The systematic literature review revealed several main challenges and strategies and by building on those
The life cycle and behavior of free-living soil nematodes is highly dependent on environmental factors such as temperature and soil moisture, fluctuations leading to significantly lower development and activity rates, dormancy and/or mortality. This literature review summarizes present knowledge about free-living soil nematode temperature and moisture requirements, as well as the commonly accepted
Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. Due to the cooling of the fire gases, the smoke layer may contract. This work focused on different parame
Children who grow up with a parent with an addiction and/or mental illness are at higher risk of developing the same disorder. There are children who even when growing up under rough conditions succeed to overcome their childhood and grow up to be “normal” citizens. These children have a high level of resilience and are usually referred to as Superkids. The aim of this study was to understand what
Syftet med denna kvalitativa studie har varit att genom en komparativ analys av Supplementary instruction (SI) och ämnet Ensemble på gymnasiet, jämföra undervisningskulturernas karaktär samt dess inverkan på elevernas upplevelse av bedömning. Studien har också ämnat identifiera om och i så fall hur eleverna ges utrymme att utveckla icke-kognitiva förmågor inom dessa miljöer. Med en hermeneutisk anThe purpose of this qualitative study has been to investigate the teaching cultures within Supplementary instruction (SI) and the subject Ensemble in upper secondary school. Through a comparative analysis of these learning environments, the aim has been to seek understanding of the pupils’ perception of assessment. The study has also intended to identify if, and in that case show how, the pupils a
Purpose: The purpose is to explore the phenomenon of utilizing corporate museums in internal branding, in order to understand what they are, how they are used and why in the context of strategic brand management in general and brands with a heritage in particular. Methodology: A qualitative multiple case study with a constructionist and inductive approach has been executed. The case companies rep
Investments are essential to any economy. Therefore, governments aim to increase the level of total investments done within a country. Investments improve the economy and the productivity of the country. For this reason, it is important to understand which factors can influence investments on a national scale. The primary aim of this study is to investigate factors that could reasonably be exp
A study is carried out on the ventilation strategies for road tunnels in different countries and consequences using fixed fire fighting systems (FFFS). The type of ventilation strategy for road tunnels can ensure the safety of people during the evacuation stages and protection of the rescue services during their intervention of the fire. Ventilation strategies vary from country to country and ther
Self-driving cars have the potential to revolutionize individual mobility. Before this can happen, however, they will have to overcome a series of hurdles, one of which will be to overcome resistance among potential users. Previous research about resistance towards self-driving cars has primarily revolved around demographic characteristics that correlate with a higher likelihood of resistance. Thi
The aim of this paper is to explore which skills and mindsets are necessary for successful leadership in the digital era. It is written for IKEA who are interested in remaining at the forefront of their industry by understanding how digitalisation affects their business and how to make the most of the opportunities it brings, one aspect of which is leadership. There is a gap in the existing knowle
With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. This thesis considers disordered/ordered inte

The time-ordered linear density response function is examined in a model study. Two model dimers are considered; one with one orbital per site and a second one with two orbitals per site. The one-orbital case has U0, the on-site Coulomb interaction, as the only parameter and is solved analytically. The two-orbital case has parameters U0, the upper orbital non-interacting eigenenergy ε1, and the ho
