In this Bachelor's thesis, a solution to the Dirichlet problem using Brownian motion is given. Brownian motion is constructed using Kolmogorov's existence and continuity theorems. Blumenthal's zero-one law and the strong Markov property in various formulations are proven. Using these results, a solution to the Dirichlet problem is given using Brownian motion. The cone condition which g
This study analyzes the return to schooling in 22 countries. More specifically, the effect on earnings of receiving a bachelor’s and a master’s degree is estimated by applying a propensity score matching approach on microdata. Unlike many other techniques, propensity score matching addresses selection bias to a higher extent making the estimates of the treatment effect on the treated more reliable
PAPR Credentials is the name of a not yet published credential scheme that provides conditional privacy for its users. This means that an administrator can choose to revoke a user's anonymity. Doing so, however, the administrator must broadcast her intention, as the success of the privacy revocation depends on the help of other users, since the administrator does not have access to sufficient
Where do the children learn? A crucial part of our social construction, education and its space, has changed and is adapting to new knowledge and studies to improve the quality of the learning process. Space should represent the values and growth of society. The changing mindset does not mean that we deny or forget theories, strategies and resources that we have developed throughout history, but
This paper studies whether the level of IPO underpricing is enforced by increased firm complexity. Evidence from a sample of 215 Swedish IPOs between 2010–2020 suggests that investor’s ex-ante uncertainty increases as issuing firms become increasingly complex. As a consequence, firms exhibiting complexity generally experience higher degrees of IPO underpricing. Moreover, we find support for our cl
Den där blomman är min! Det är juni. Vart man än vänder blicken är det grönt och blommorna står som vackra färgklickar i allt det gröna. Fjärilar, bin och andra insekter surrar omkring bland blommorna i jakt på föda. Det myllrar av liv och olika arter. Men vart ifrån kommer egentligen all den mångfald av växter och insekter som vi ser? För att förstå biodiversiteten runtomkring oss och hur olikaA significant proportion of the diversity of species seen today are insects and their host plants, and the evolutionary mechanisms behind their radiation have long captured the interest of biologists. The peacock flies of the large genus Tephritis (Tephritidae) use different host plants in the family Asteraceae for their reproduction. There is variation both in use of host plant species and in the
How to study the infection of a parasite without using cats During the past 9 months, I have been studying a parasite, more specifically, how we can study the life of this parasite in the lab without using lab animals like mice or cats. I have tried and achieved to developed a way to do so, with mouse cells and a special fatty acid A parasite is a type of organism that depends on another living
Exploring the genetic basis of familial multiple myeloma Multiple myeloma (MM) is one of the most common forms of blood cancer. The disease is characterized by uncontrolled growth of plasma cells in the bone marrow, leading to bone marrow failure, kidney failure, bone lesions and death. Several studies have shown that some families are at an increased risk of developing MM, monoclonal gammopathy
Architecture is always intrinsically tied to place. Regardless of how architects choose to interact with and study it, the context our buildings are meant to inhabit is an important piece of the puzzle. As the world is getting more interconnected and geographical constraints are getting less important to the architectural profession, I am interested in how the creative process changes when assumpt
We study the impact of research and development (R&D) intensity on acquisitions in R&D intensive industries. First, we look at the impact of target R&D intensity on acquirer return to see if it is affected by acquisition premiums. Second, we study the impact of target R&D intensity relative to acquirer R&D intensity and look at whether this impact is affected when the companies
Målet med denna uppsats var att undersöka vilken bild av Frankrike som kulturproducent som förmedlades av svensk rikstäckande dagspress, i det här fallet Dagens Nyheter och Svenska Dagbladet, under år 2020. Genom att genomföra en kvalitativ innehållsanalys av samtliga recensioner av fransk kulturproduktion publicerade i de båda tidningarnas kulturdel under det valda året ville jag få fram utrymmetThe goal of this thesis was to conduct a study in what image of France as a cultural producer that was mediated by the Swedish national press, in this case Dagens Nyheter and Svenska Dagbladet, during 2020. By implementing a qualitative content analysis on all of the reviews on French cultural production published in the chosen newspapers’ cultural section throughout the year, I wanted to examine
Entrepreneurial Passion has been directly and indirectly related with positive outcomes such as improved self-efficacy, persistence, and venture performance. However, an underexplored concept within entrepreneurship research is Team Entrepreneurial Passion, and to our knowledge there is no research on the interplay between Entrepreneurial Education, individual Entrepreneurial Passion and the emerg
Agricultural intensification is seen as a major threat to global biodiversity. Semi-natural grasslands play an important role in maintaining biodiversity in agricultural landscapes. Biodiversity and community structure in semi-natural grasslands depends not only on local management but also on the surrounding land-use. Further knowledge on landscape-scale effects would help improving the managemen
Avian influenza constitutes a remarkable threat to global health. Interaction between wild and domestic ducks in the natural wetlands has been considered one of the potential risk factors for the rapid spread of the avian influenza virus. Tanguar haor is one of the vital wetlands in Bangladesh, a wintering place of millions of migratory birds. At the same time, native farmers raise their domestic
Sexuella övergrepp tillhör ett av de mest kränkande och traumatiserande brott som en människa kan utsättas för. Trots detta förekommer det på flera håll än idag motstånd att klassificera bekantskapsvåldtäkter eller våldtäkter inom relationer som ”riktiga våldtäkter”, medan våldtäkter av obekanta gärningsmän eller med förekomst av våld inte sällan förstås som en ”riktig våldtäkt” och mest allvarligSexual offences are one of the most offensive and traumatic crimes a person can be subjected to. Despite this, there is still resistance in several places to consider acquaintance rapes or rapes in relationships as ”real rapes”, while rapes by unknown perpetrators or with violence often are understood as the ”real rape” and the most serious ones. Those perceptions might thus lead to a situation wh

In an increasingly online society, scholars have gradually come to scrutinize the ad tech industry. The research field, however, tends to focus on the most visible tech giants, such as Google or Facebook, and few researchers approach the industry from a human rights perspective. This thesis deals with some relatively unknown, but still massive, ad tech companies and unveils how they operate at the
Electricity finds itself different from other fresh-ware commodities, it cannot easily be stored. This characteristic trait of electricity results in traditional pricing methods not working for electricity pricing. Thus different pricing schemes are needed, such as Price Forward Curves (PFC) or pricing against a price level. The price forward curves are constructed through a mix of historical mark
