Molecular diversity and host specificity in ectomycorrhizal communities in the tropical forest of Yasuní National Park, Ecuador

Cooperation in soils can make a huge difference At a first glance, the coexistence of diverse plants in ecosystems seems to be completely harmonious. However, there is a high competence of these organisms for obtaining resources. In this scenario, most of the plants have decided to make a lifetime deal with fungi in order to ensure their development and survival. This symbiotic association is cal

Returns to schooling and potential signalling effects: Estimates based on ISSP data on Sweden

This thesis estimates the returns to schooling in Sweden for working individuals by applying the Mincer equation on three datasets from the International Social Survey Programme and compare the results to assess potential trends. It also investigates if there is any difference in returns to schooling for men and women and if there seem to be any signalling effects present. The estimates indicate t

Signs From Above

This thesis looks into cross-cultural in-store marketing and how, with the use of contemporary symbols, marketing messages can cross language barriers. In the context of cosmopolitan cities with large populations of international inhabitants, being able to market to all individuals regardless of linguistic abilities and cultural backgrounds is critical for firms to stay competitive. Simply replaci

Digital tidssamordning av masshantering vid dammbyggnationer

3D-modeller är grunden i det som kallas BIM och är något som används mer flitigt inom byggbranschen men desto mindre inom anläggningsprojekt. BIM har utvecklats mer och mer för att underlätta samordningen av flera aktörer och lösa konflikter i olika faser och skeden. Med ytterligare dimensioner integreras även tid och kostnadsaspekten på projektet som resulterar i ett mer produktivt byggande. Gru3D-models are the base of what is called BIM. It is used more and more within in the construction industry over all, but not as much in the field of infrastructure projects. BIM is developed to coordinate several actors and resolve conflicts in different phases of the construction. With dimensions integrated in the model, such as time and cost aspect, it result in a more productive project. The m

Value Co-Creation: Multiplayer

This study is an initial attempt to investigate value co-creation in the gaming industry by looking at Value Co-Creation through a framework called The Value Co-Creation Egg. The aim of the framework was to identify the mechanisms of The Consumer and The Company, which ultimately led to a deeper understanding of how these actors operate within the context of The Market. To understand The Consumer,

Long-Term Effects of Distributed Profit Taxation on Firms: Evidence from Estonia

The study contributes to a body of research on a specific corporate taxation system, distributed profit taxation, by examining whether the system has affected corporate behavior in the long term and if it has, to what extent. The results partly corroborate previous literature but provide new evidence on the long-term effects of distributed profit taxation. We show that compared to classical gross

Disease susceptibility may be increased by accumulation of genetic variants in chromatin loops from disease-relevant cell-types

Genome-wide association studies (GWAS) have identified more than 50,000 SNP-trait associations. Most of these SNPs or genetic variants map to noncoding regions, known as or gene desserts. This makes it challenging to describe the mechanism by which the variant confers susceptibility to the trait. Increasingly, there is an interest in characterization and interpretation of the effect of non-coding

Kvalitetsarbete i organisationer

Syftet med denna undersökning är att identifiera faktorer som påverkar chefers möjligheter att bidra till ett välfungerande kvalitetsarbete i organisationer. Bristande engagemang och okunskap hos chefer har enligt forskning visat sig vara en av de största anledningarna till att kvalitetsarbete misslyckas. Chefer är viktiga i arbete med kvalitetssäkring av verksamhetsprocesser i organisationer. På

Daylight optimization in an office building through atrium improvements

Daylighting has become a fundamental measure not only to decrease the electrical energy demand in buildings, but also to provide good indoor comfort for the occupants. Atria have been implemented in buildings since old times as a space to foster interaction and provide indoor comfort through ventilation and daylight. However, the implementation of this feature can be complex if good natural light

Skonsam föryngringsmetodik för bok- och ekskogar - En studie med fokus på Bruces skog i Helsingborg

Skonsam föryngringsmetodik för bok- och ekskogar i naturreservatet Bruces skog Ädellövskog är ett vackert inslag i den svenska naturen och är viktig för rekreation och människors välmående. Lövskogar och särskilt bok och ek är viktiga för den biologiska mångfalden och skogens ekosystem. Genom att ha mycket lövträd blir skogarna mer levande och hyser fler och mer sällsynta arter. Dessa arter är berDeciduous forests and especially oak (Quercus robur) and beech (Fagus sylvatica) are very important for biodiversity and provide habitats for many threatened species. They are also good environments for recreation. Bruces forest in Helsingborg is a nature reserve where rejuventation of deciduous forest is a main objective. Hence, this study examined factors influencing rejuvenation, different reju

Sápmi and the Return of Beowulf: A Socio-Legal Analysis of the Gállok (Kallak) Case

This study aims to analyse how the Swedish media has been framing the Gállok case and the events surrounding it. Moreover, it seeks to understand which meaning is attributed to the concept of Sámi customary law within the Gállok process and decision-makings. This is done through Fairclough’s critical discourse analysis. They study is based on a theoretical framework that has its starting point in

Forecast-based Financing: Developing triggers for drought

Forecast-based Financing (FbF) is a rather new concept within the humanitarian world, which enables actors to act before a likely disaster, based on forecasts. In this study, two scoping studies and five interviews with FbF experts were conducted to find out how to develop useful triggers for drought. The study finds that the triggers must be contextualized, as drought differ a lot across the glob

Ekosystemtjänster från sjögräsängar i Östersjön

Ekosystemtjänster från sjögräsängar i Östersjön Östersjön bidrar med både ekonomiskt och socialt till länder runt i kring det. Detta tillsammans med viktiga biologiska företeelserna Östersjön producerar kan sammanfattas till ekosystemtjänster. Innanhavet utsätts dessvärre hela tiden för både globala, regionala och lokala påfrestningar. Vilka i sin tur utgör hot mot både biologiska, sociala och ekEcosystem services is a relatively unexplored term in environmental science and in the society as well. The concept can seem rather abstract and difficult to understand to the public but it does not have to be. The term could seemingly help the public to understand why certain ecosystems and natural objects need to be preserved not only for their intrinsic value but also hence economic and social

Lateral variability in the quantification of calcareous nannofossils in the Upper Triassic, Austria

Kalkskaliga nannofossil är spår av mikroskopiska organismer som utvecklades signifikativt under och efter slutet av trias, vilket kan ha påverkat havskemin samt kalkbildning i haven. Coccoliter, nannoliter och kalkskaliga dinoflagellater är vanligen förekommande kalkskaliga nannofossil som påträffas i övre trias. Denna studie syftar till att kvantifiera och undersöka laterala variationer hos kalksCalcareous nannofossils are microscopic remains of organisms that diversified considerably in and after the Late Triassic, and which may have influenced seawater chemistry and carbonate production. Coccoliths, nannoliths, and calcareous dinoflagellate cysts are important parts of many calcareous nannofossil assemblages in the Upper Triassic. This is a quantification study of an Upper Triassic lime

Measurement of the relative static permittivity and miscibility of ternary CO2-expanded green solvents

Lösningsmedel är vätskor i vilka nästan all kemi utspelar sig, såsom tillverk- ningen av kemiska ämnen (t.ex. mediciner), extraktioner av ämnen, eller separationer av olika ämnen. Inom framförallt läkemedelsindustrin används enorma mängder lösningsmedel, vilket är ett stort problem eftersom nästan alla vanliga lösningsmedel är giftiga, miljöfarliga, och brandfarliga. Så kallade gröna lösningsmedelCO2-expanded liquids (CXLs) are a class of solvent systems that have shown great promise as a green and effective medium in synthesis, catalysis, extractions, and analytical separation methods. Unfortunately, not much information is available on the polarity and miscible compositions of CXL systems, information which is crucial for selecting the right solvent system for a particular application. H

Mad or Misunderstood? A Study of the Different Portrayals of Mr. Rochester's First Wife in Jane Eyre and Wide Sargasso Sea

Jane Eyre (1847), written by Charlotte Brontë, remains a classic, 170 years later. Mr. Rochester’s secret wife locked away in an attic, Bertha Mason, is the antagonist in the novel. However, in Wide Sargasso Sea (1966) written by Jean Rhys around a century later, the character has been rewritten as Antoinette Cosway. This essay examines how Bertha and Antoinette are written and investigates the as

Syndicated Lending and Antitrust

Discussion on whether syndicated loan structures may give rise to anticompetitive risks has been increasing thus the European Commission is performing a study on the impact syndicated lending structures have on competition in the credit markets. This thesis will cover the main aspects of syndicated loan structures and then examine Article 101 TFEU and anticompetitive conduct. Syndicated lending h

Browsing Lawns in a Landscape of Fear - The impact of wolves on browsing lawn structure in the Białowieża Primeval Forest, Poland

The Białowieża forest is one of Europe’s only remaining lowland broadleaved forests still containing a complete contemporary assemblage of browsing ungulates and predators. The presence of gray wolves (Canis lupus) causes behavioural responses in browsing ungulates, the result of which has an impact on lower trophic levels. The impact of this top-down control on browsing lawns (areas of trees main

(Re)Articulating Sexual Citizenship: Between Queering the Urban Space and Subjugating the Queer

In today’s post-industrial cities, how urban citizenship is defined and performed have been ambiguously positioned in their relationship with the urban societal space. While the cities become more commodified and privatized with the inter-urban competition, the concept of citizenship is put into a tentative position between being participatory political subjects and passive consumers. Sexuality, i
