Decomposing the decoupling of road-based traffic emissions and economic growth: Regional disparities between the national and city-level in Germany during 1999-2013

The process of decoupling is often considered to fulfil the prediction by the Environmental Kuznets Curve hypothesis that negative environmental externalities diminish with increasing income. Recent research has found many instances of delinking between economic growth and environmental harm on the national level across the globe. This study examines the development of the relationship between eco

Correlated Structure-Property Investigation of Ultrathin InAs Nanowires

III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a

Environmental, social and governance composite ratings and stock performance

This paper studies the effect of non-financial performance on the stock performance of companies. By using ESG ratings from the Thomson Reuters Eikon DataStream we were able to sort the companies into portfolios of high and low ESG performance. The study finds that low scoring ESG companies significantly outperformed their high scoring counterpart for the period 2010-2015 but that the difference c

Emotion Classification with Natural Language Processing (Comparing BERT and Bi-Directional LSTM models for use with Twitter conversations)

Vi har skapat en modell som känner igen vilken underliggande känsla som finns i en konversation på Twitter. För att utvärdera hur bra vår modell är har vi jämfört med BERT, en större modell skapad av Google. Det vetenskapliga fält som handlar om hur datorer behandlar text heter natural language process- ing (NLP). Ett vanligt problem inom NLP är hur datorer ska förstå olika mänskliga känslor. I våWe have constructed a novel neural network architecture called CWE-LSTM (concatenated word-emoji bidirectional long short-term memory) for classify- ing emotions in Twitter conversations. The architecture is based on a combina- tion of word and emoji embeddings with domain specificity in Twitter data. Its performance is compared to a current state of the art natural language process- ing model fro

En grönare Vårmarknad

Den svenska turismnäringen växer. Under 2017 omsatte turismnäringen i Sverige 317 miljarder SEK, en ökning med 7,4 % från föregående år (Tillväxtverket, 2018). Fler event och ökad turism medför en ökad påverkan på miljö och klimat men samtidigt fler arbetstillfällen och gynnad samhällsutveckling. I samband med detta väljer flera arrangörer att på ett eller annat vis hållbarhetsmärka sitt evenemangThe Swedish tourism sector is expanding. The turnover of 2017 ended on 317 billion SEK, which is an increase with 7,4 % from the year before (Tillväxtverket, 2018). Increased tourism and more events lead to a bigger impact on the environment while at the same time enhancement in tourism development. Which in turn leads to positive effects on both local development and employment. This study aims t

Blockchain Technology in Disaster Risk Management: Transforming the Delivery of Emergency Relief

Persisting challenges such as corruption and a lack of coordination among humanitarian organisations continuously lead to almost a third of all development assistance not reaching those in need. As various attempts of solving this dilemma have not been successful, an innovative approach is required. Organisations such as the World Food Programme have started to trial the use of blockchain technolo

Here to be Heard : Digital feminist engagement with #MeTooinChina

This study analyses Chinese people's engagement in #MeTooinChina against sexual assault and patriarchal norms in Chinese society by asking three main research questions: 1) Why and how do Chinese people engage with #MeTooinChina? 2) What challenges are they faced with in their engagement and how do these challenges influence their continuous engagement with #MeTooinChina? 3) How do they reflec

Elbow design, servo motor selection and control implementation of the Agile Parallel Kinematic Manipulator

The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame. A principle design wil

Increased traceability of recycled cardboard and containerboard packaging with the help of blockchain technology

Producers in the cardboard and containerboard packaging industry want to, and are sometimes forced to, increase the amount of recycled fibers in packaging, but there is no way to confirm the actual composition of fibers by examining the material optically or chemically. Blockchain technology is often seen as a promising technology for data storage and it is argued that it can help increase transpa

What goes up, must come down

Rising levels of greenhouse gas emissions and their detrimental impact on the environment are at risk of jeopardizing global development achievements and limit future economic growth. In an effort to decarbonize the energy sector, the global community has pointed to renewable energy sources as a flagship technology. Estimating the long- and short-run relationship between emissions, income and the

An Ex-Post Utilization Study of the Sino-Swiss Free Trade Agreement in the Swiss Watch Industry

This thesis contributes to the growing body of literature which examines the utilization of Free Trade Agreements (FTAs). The Sino-Swiss Free Trade Agreement (SSFTA) was not only China’s first FTA with a continental European country, but also a milestone for the Swiss foreign policy. However, the Swiss government needs to demonstrate that the SSFTA works in practice and delivers the negotiated ben

Unpacking followership in a management consultancy

Purpose – The purpose behind our study was to understand how individuals socially construct followership in a management consultancy. We did this through exploring the relations between consultants and their selected leaders, as well as through exploring how they related to the notion of followership. Literature review – We selected theory that was relevant with respect to our research question a

Derivation of an Algorithm for the Analysis of Images of DNA molecules prepared with Denaturation Mapping

Denaturation mapping is a powerful and fast method for optically analyzing DNA molecules.It can be used to characterize DNA molecules on a scale of a few hundred base pairs which is sufficient for applications. Denaturation mapping requires a sufficiently high optical resolution of the imaging system used, which typically translates to an expensive, bulky microscope. For point-of-care testing or u

The Act of the Pitch

The entrepreneurial pitch plays an integral role in attracting financial capital for a new venture. Notably, previous research has shown that (1) female entrepreneurs are often subjected to discriminatory practices when applying for external capital and (2) entrepreneurs’ communication skills and personal attributes influence investor decision making. Building on these findings, this study explore

More urban, more unequal? Urban agglomeration and income inequality (1955-2015)

There is an ongoing debate if urbanization and larger city sizes should be promoted for increasing economic growth at the expense of rising income inequality. The primary purpose of this study is to determine if the relationship between income inequality and average urban agglomeration size is the same for developed and developing countries. Data for this study were combined from different sources

GIS som stöd för krishantering i ett operativt skede på lokal nivå

När en kris inträffar är det väsentligt att snabba och lämpliga beslut fattas för att begränsa dess konsekvenser. Studien har undersökt om GIS (geografiska informationssystem) kan stötta krishanteringen på lokal nivå. Ett exempel på hur GIS kan användas som många personer kommer i kontakt med i sin vardag är vägbeskrivningar genom tjänster såsom Google Maps, men det har en potential att göra så mBoth studies on and the application of GIS-systems during several disastrous events has shown a potential of the technology to facilitate for decision makers to make quick and suitable decisions to limit the impact of an event. In Sweden the primary responsibility for a crisis is held by the municipality in which the crisis occurs, which motivates an interest in investigating how GIS can support m

Evaluation of applicant quality for a recruitment company using machine learning

It is important to the recruitment company that only quality candidates, and the candidates most likely to receive an offer of employment get short-listed to go through the carriers selection process. It is this second phase of the recruitment process, the short-listing of potential candidates, that will be the focus of this thesis. Data has being gathered by the recruitment company through an i
