Forskningsfrågor: Är det statistiskt signifikant att det finns en förändringar i aktieavkastning på optionens förfallodag i den underliggande aktien? har de öppna options kontrakten en påverkan på aktieavkastningen på optionens förfallodag? Syfte: Syftet med examensarbetet är att undersöka om det finns en signifikant skillnad i aktieavkastningen vid optionens förfallodag i relation till de öppna Research questions: Is there significant change in the stock return on option expiration dates in the underlying stock? Does the net open interest have an effect on the return of the underlying stock on option expiration day? Purpose: The purpose of the bachelor's thesis is to study whether there is a significant difference in the stock returns on option expiration dates in relation to the ne

Min utgångspunkt har varit de senaste årens trendbrott i boendepreferenser, där storstäderna inte växer i samma takt som tidigare. Allt fler söker sig till platser med stort utbud av småhus, närhet till natur, goda förbindelser till arbete och rimligare kvadratmeterpriser. Till följd av detta har flera mindre kommuner och orter fått en skjuts i befolkningstillväxt. En av dessa kommuner är min egOver the last years the bigger cities in Sweden haven’t grown at the same speed as before. There has been a rising trend of people choosing to live outside of the big cities as they tend to look for areas with proximity to nature, large selection of small houses, good connections to work and more reasonable square meter prices. As a result, several smaller municipalities and towns have received a

In the last century, agricultural intensification has led to loss of permanent pastures in the landscape which has been correlated with a loss in biodiversity. Specifically, small specialist species are more negatively affected. Often because they have a higher demand on suitable complementary habitats, larger home-range requirements of a high quality. Small species also have a lower mobility and

Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. One such model is the HP model, where the protein is represe

Purpose: The primary aim of the study is to investigate the influence of AI-driven personalized advertising on customer loyalty and brand engagement within the B2C market. The research will also examine how consumer perceptions of privacy and transparency in the use of AI impact these relationships. Theoretical perspective: The study’s literature review explores AI-driven personalized advertising

The start-up company LEVTEK is launching a new ultralight electric utility vehicle called the LEVKART. The Levkart uses a combination of robotics and AI-technology to offer semi-autonomous or autonomous riding and usage. The purpose of the vehicle is to serve as an alternative to cargo bikes and electric scooters designed for easy usage and as a more sustainable option to fossil-based transport. T

Recently, the growth of social media has become an essential element in consumers’ daily lives. The widespread use of social media allows users to experience different kinds of content online and also be exposed to influencers-generated content. Moreover, social media allows influencers and consumers to share their opinions and interact as well as create communities through digital platforms. Thi

The aim of this study is to better understand the goals and tasks of municipal activation workers, inquire into their perceived ability to establish their clients on the labor market, and examine their handling of hard-to-activate clients. The data was gathered through individual interviews with six activation workers who were all part of the same municipality. Four of them worked with youths and

With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. This thesis investigates different aspects of optimizing one important component

Objective Second language learning continues to be a field of growing interest both in academia and everyday life. As such, a more comprehensive understanding of the best learning methods remains an important area of focus. This study aimed to investigate single-session vocabulary acquisition and neural underpinnings of language learning through Diffusion Tensor Imaging (DTI), in relation to immer

Prediction of flood and evaluation of the impact of climate change in a catchment needs to be correctly estimated, which can be accomplished by hydrological modelling in HEC-HMS. In this paper, the objectives were to gain an understanding of the rainfall-runoff process and estimate the flood frequency curve in the Kävlinge River Basin. However, due to the complexity of a catchment, models should b

In this study the dangers of Listeria monocytogenes presence in food and the problem it creates for general food safety is presented. The aim of this study was to highlight the importance of food safety, especially when it concerns Listeria monocytogenes. The study should also give an insight to the part that Listeria monocytogenes plays among food and the risks that follows. Furthermore, it wil

In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a

During the 90’s intersex individuals was found among fish downstream sewage treatment plants, this was found to be due to estrogens in the water. Today we know that one of the largest contributors of the effects on fish is 17a-ethinylestradiol (EE2). EE2 is a synthetic estrogen used in contraceptive pills and is one of the most used pharmaceuticals in the world. In addition to intersex EE2 also ge

In majority of academic literature related to BDSM (bondage-discipline, dominance-submission, and sadism-masochism) the focus is often centred on men and their experiences within the community. The limited focus on women and their motivations to engage in BDSM dynamics has been a driving force in this thesis. Therefore, this research aims to address this gap and explore female BDSM practitioners&#

This thesis highlights the research and development of a new plastic-scintillator detector for time-of-flight measurements in relativistic heavy-ion beam experiments. The detector makes possible the identification of different ion species on flight distances as short as a few meters. The novelty lies in the design approach of using many moderately fast, independent measurements of every physical e

Per- and polyfluoroalkyl substances (PFAS) are of high concern for the environment, wildlife, and human health due to their persistence and potential to cause adverse health effects. Despite political measures to restrict the production and distribution of PFAS and to limit the exposure of populations, PFAS can be measured at commonly high detection frequencies in human samples. Thus, this pilot s
