This thesis introduces TrustNet, a flexible and distributed system for deriving, and interacting with, computational trust. The focus of the thesis is applying TrustNet as a tool within distributed chat systems for implementing a subjective moderation system. Two distributed chat systems, Secure Scuttlebutt and Cabal, are discussed, the latter having been extended with a proof of concept implement
This project investigates what human interaction is and how we collaborate within the confines of finite resources. The project ex- amines what could be done to minimise the need of ownership and instead reconnect the human to the collective by encourag- ing sharing. The method used to achieve this will be an in-depth design process. The investigation is conducted from the stand point of a Swe
Studiens syfte är att få fram hur FN ser på sexuella övergrepp som utförs av deras egen personal. Jag har utfört en diskursanalys utifrån frågeställningarna om det pågår ett förebyggande arbete inom FN för att stoppa sexuella övergrepp och hur FN talar om övergreppen och förövarna. Teorin jag använder mig av är R. W. Connells teori om maskulinitet som utgår från tre relationstyper och fyra maskuli
Probiotics are living microorganisms which could induce a potential health benefit to the host when consumed in adequate amounts. Among the different probiotics in the market, Lactobacillus reuteri strain DSM 17938 is a microaerophilic and heterofermentative organism that is able to tolerate high oxygen conditions compared with another L. reuteri and lactic acid bacteria strains. This study invest
The development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl
Today, 55 percent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 percent by 2050. The cities are growing, densifying and expanding. On the dark side of urbanization and rapid growth, the city centres work as dense machineries for businesses, commerce, automobiles and computerization. As a result, significant numbers of urban citizens are experienc
The literature suggests that executives still doubt the real contribution of HR, and one reason for this is that it is difficult to measure the Return on Investment in HR activities. In addition to this, earlier studies on the value creation of IT seems to discount the intangible value creation that IT investments bring to organizations. The purpose of this thesis is to investigate and compare how
This thesis is about predicting the average ten minute closing bid price of the USD/SEK exchange rate by applying deep learning methods. First, the time lag method is applied for the vanilla Feedforward Neural Network (FNN) to undertake one-step prediction. Secondly, three univariate Long Short-Term Memory (LSTM) models are used to undertake one-step and multi-step prediction. Each network is theo
Exposure to skin sensitizers on a daily basis has been leading to a high prevalence of allergic contact dermatitis (ACD) among the general population. Single substances have been thoroughly studied for their skin sensitizing potential, yet little is known about the cellular mechanisms of so-called “cocktail effects” of mixtures. It has been suggested that induction of oxidative stress, and more re
Knowledge about thermal properties of nanoscale graphite is essential in order to realize the many promising applications of carbon based nanomaterials. This thesis reports how samples of thin graphite films on nickel substrates were investigated using time-resolved X-ray diffraction (TRXD) at the FemtoMAX beamline at the MAX IV facility. Through these investigations the thermal conductivity of th
What goes into the development and production of a modern backpack for off- piste skiing? How is a backpack made and what is right now requested on the market? A skiers backpack is a project about making a new off-piste skiing backpack for the Swedish brand Fjällräven. It combines the values of the Swedish brand with my own thoughts about how a product like this should be and function. Th
The social and environmental impacts associated with corporate water use and discharge in Kazakhstan is historically high, and in certain watershed pose a significant threat to the health of the local communities and ecosystems. Today the industries are consuming almost a third of freshwater and remain one of the biggest polluters in the country. The situation is aggravated with the changing clima
In recent years, the global problem of plastic waste has received increasing attention. Plastic waste is frequently traded good and is often exported to countries which mismanage large proportions of their waste. By investigating Germany’s imports and exports to a selection of countries this study finds that the German recycling system has flaws in the area of plastic waste. Due to the fact that p
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
Syftet med denna uppsats är att undersöka och mäta förekomsten av diskriminering av personer med utländsk bakgrund på Malmös arbetsmarknad, specifikt restaurangbranschen. Uppsatsen belyser även diskrimineringen som de arbetssökande i sådana situationer utsätts för. Undersökningen genomförs med hjälp av metoden Correspondence testing där två fiktiva personer, en med svenskt namn och den andra med u
På sociala medier tar människor sig friheter när det gäller användningen av bilder på barn, och det framförallt inom humanitära organisationer och företag. Bilden på barnet, används som ett politiskt verktyg för förändring och som en empatiförhöjare för att få målgrupper att agera. Fenomenet är något som numera även syns bland kändisars och influerares sociala plattformar, vilket skapar en stor sp
Uppsatsen ämnar bidra till förståelse i en pågående politisk och aktuell debatt, gällande rättsliga vägar att hantera svenska medborgare som är återvändare från Islamiska staten. Enligt en innehållsanalytisk metod genomförs en granskning av protokollet från den aktuella riksdagsdebatten om IS-återvändare 12 mars 2019. Utifrån ett teoretiskt perspektiv om mänskliga rättigheter och rättssäkerhet för
