This paper examines the effect of European corporates’ sustainability performance on their economic and financial performance. The sustainability performance is represented by ESG scores in this paper. ESG evaluates the sustainability performance in environmental, social and governance aspects. The financial performance is measured as the average monthly stock return from January 2002 to July 2018
Hans Palmstierna was a biochemist and writer on environmental issues who became the foremost public voice of the early environmental movement in Sweden during the late 1960s and early 1970s. The books he authored warning of escalating environmental concerns became bestsellers, and he wrote a large number of articles on matters of scientific progress, energy politics and pollution in Swedish newspa
“The majority of females are selfish and don’t want to help us lonely men out”- A netnographic study about men who are incels Incel, is short for and means “involuntary celibate”. The purpose of this study was to observe an Internet forum for incels and to examine incels self-images and social context in selected threads. Also, to see the men's perceived reality and how they describe themselv
Sociala medier är idag en stor del av våra liv och ett område i ständig utveckling. Syftet med vår studie var att undersöka skolkuratorers förståelse och beskrivning av hur sociala medier inverkar på ungas psykiska hälsa. Studien genomfördes med hjälp av en kvalitativ metod. Vi genomförde semistrukturerade intervjuer med sju olika skolkuratorer från grundskolor som representerar olika områden. För
Filling Urban Gaps, is a study on a dense and central area of São Paulo, Brazil which is cut by an elevated highway. Its construction affected the development of the whole area, decreased its value, and affected many people around it. In recent years the debate of transforming the highway in a park, and opening it for pedestrians on weekends boosted the area as a cultural spot. Now the city announ
The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. In the conversion between blue light and light of lower energy approximately 25-45 % of the radiant power is lost
With sustainability at the forefront of many cities’ urban development plans, it is possible that sustainable polices are targeted to attract a certain group of inhabitants. Malmö, Sweden, has implemented changes in order to gain international recognition as a green city but has also been experiencing growing residential segregation. The presence of urban greening projects is a keystone to human h
Bakgrund: Preoperativ oro och ångest kan ha negativa konsekvenser på det perioperativa förloppet. Förutom ökat lidande, kan det öka behovet av anestesiologiska läkemedel, förekomst av postoperativ smärta och illamående samt ge förlängd vårdtid. Syfte: Att belysa patienters upplevelser av oro och ångest inför generell anestesi. Metod: En litteraturöversikt med 14 kvalitativa studier analyserade i e
This thesis examines some of the multiple variations of the previously established Rules of Thumb; which are used in attempting to explain implied volatility sur- faces. Here, these Rules are extensively tested on the Swedish stock market index (OMXS30) using rolling window analysis and linear stepwise regressions with for- ward selection. Data is collected on options at four different maturities
Increasing waste generation levels are presenting a multitude of issues from both low and high- income countries around the world. High levels of greenhouse gas emissions, water contamination and ecosystem endangerment are all concerns that are exacerbated by improper management of waste. Major shifts in the waste management sector are necessary in order to tackle these issues sustainably and for
Syfte: Syftet med studien är att undersöka vilka attityder, utmaningar och möjligheter det finns i branschen gällande förändringsarbetet vid implementering och användandet av ett nytt digitalt arbetssätt. Studien lägger fokus på förändringen av en given process från manuellt skriven pappersföljesedel till digital följesedel för leverantörer av transporttjänster samt åkerier. Frågeställningar: 1.
Bakgrund: Ungefär 90% av patienterna som genomgår anestesi utvecklar atelektaser. Atelektaser kan i sin tur ge upphov till inflammatoriska processer som postoperativt kan leda till lungkomplikationer. Syfte: Syftet var att beskriva vilka av metoderna preoxygenering, PEEP, CPAP, lungrekrytering och låga tidalvolymer som är mest effektiva för att minska förekomsten av atelektaser hos vuxna som genom
In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. In this bachelor thesis, these droplets were numerically stud
A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation. Without the ability to select and enhance a specific sound source of choice while suppressing the background, the hearing aid
The increased capacity of elementary particle accelerators raises the demand for the simulation data of the experiments. One of the bottlenecks in the simulations is the QCD color structure calculation, which is usually treated using non-orthogonal and overcomplete sets of bases. The computational cost could be decreased significantly if orthogonal bases, such as the multiplet bases, were used ins
