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

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

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

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

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

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

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

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

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

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

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 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

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

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

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

Inom industrin används många typer av värmekällor. Det kan vara öppna lågor, IR strålning, resistiv uppvärmning eller induktionsvärmning. Induktionsvärmningen är en värmingstyp med hög energidensitet, låg investeringskostnad, snabb uppstartstid och hög flexibilitet. Ett serieresonant induktionsvärmningssystem består i sin enklaste form av en växelspänningskälla, en spole, en kondensator och objektMany different types of heat sources are used in the industry. Some of these are open flames, IR-radiation, resistive heating and induction heating. Induction heating is a heating technology that have a high energy density, fast start up times and high flexibility. A simple series resonant induction heating system consists of a voltage source, a capacitor, an inductor and the object to be heated.

Electricity differs from other commodities in that it cannot be stored. This non-storability characteristic results in traditional pricing methods for commodities not being applicable for electricity. An alternative pricing method is therefore needed and the solution is the Hourly Price Forward Curve (HPFC). The HPFC essentially gives the prices as of today for the delivery of electricity at each
