Under början av nittonhundratalet började det bli känt att det fanns mer till världen än man tidigare trott. Det fanns en helt ny arena med helt nya spelregler: Kvantvärlden. Albert Einstein lade grunderna för den fotoelektriska effekten, varvid ljus används för att jonisera atomer genom en process där en atom absorberar ljus, och därmed energi, för att sedan avge en elektron, en så kallad fotoeleIn this work, we employ a semi-classical approach to light matter interaction to describe and char- acterize spin configurations resulting from quantum correlations between electrons created by a photoemission event and by the following Auger decay. The system studied consists of three atomic levels and two continua. Initially, an external classical light field, in the form of a narrow Gaussian pa

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.

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. FörSocial media is today a large part of our lives and an area of constant development. The purpose of our study was to investigate school counselors understanding and description of how social media affect young people's mental health. The study was carried out using a qualitative method. We conducted semi-structured interviews with seven different school counselors from elementary schools that

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

Over the last years, concerns have been expressed by the media and scientific literature about baile funk and Brazilian funk in general. Brazilian funk is a rebellious Brazilian music style which rose from the favelas from the 1980s onwards. Baile funk refers to funk dance parties which have a violent and aggressively sexualized nature. It is regarded as an expressive cultural phenomenon and it is

Recently, engagement and communication have started to be researched from a coworker-perspective. Yet, this study problematizes that most research in strategic communication and employee engagement still takes a managerial perspective and lacks critical and complex assessments. This case study therefore aims to analyze coworkers' perceptions of their communicative roles as team members, co-lea

The aim of this study is to contribute to previous research on the use of Prospective Payment Systems (PPS) based on Diagnosis Related Groups (DRG) in Sweden with an extended evaluation of variation in the utilisation of the system on recent data. This study looks specifically at within county financing and the role the system has played on the performance and behaviour of Swedish hospitals in reg

The continuous and on-going enclosure of the commons has been identified as critical for the expansion of capitalism, through processes of dispossession, expropriation and commodification. In the light of the rapid erosion of our cultural and environmental common pool resources, the concept of the commons is increasingly gaining interest, since it presents new political and cultural perspectives a

The student group is an emerging target with high potential for both the service industry and municipalities. However, previous studies scrutinizing this segment have been limited despite its significance. The aim of this study is to provide a deeper understanding of how domestic and international students perceive Helsingborg city and to offer insight into the key factors influencing students’ pe

Pornografiskt material är idag mer etablerat och tillgängligt än någonsin. Hur den ökade förekomsten, spridningen och konsumtionen av pornografi påverkar ungdomar präglas av såväl olika åsikter som forskningsresultat. Med frågeställningen “Hur arbetar sexologer i sin profession med ungdomar/unga vuxna i frågor som rör pornografi?” var syftet med den här uppsatsen att utforska hur professionella up
