Mörk materia upptäcktes redan på 1930-talet av astronomer via sin enorma gravitationella påverkan på galaxer. Trots detta, har alla försök att hitta dess beståndsdelar via experiment misslyckats. Ledande modeller för den mörka materians natur brukar beskriva den som uppbyggd av så kallade ”WIMP:s” (weakly interacting massive particles) som översätts till ungefär: ”svagt interagerande massiva partiRecently, a number of experiments have been proposed with the aim of finding light dark matter. In particular, the proposed LDMX experiment is meant to utilize electron scattering off metal nuclei to excite dark matter emissions. Motivated by this, we construct an event generator for electrons scattering off metal nuclei. The relevant kinematics are presented in detail. The matrix element for the

The rate of global urbanization in the 21st century has been unprecedented especially in the African and the Asian continents. Urbanization typically causes a removal of natural vegetation and replacement of same with impervious and non-evaporative urban materials with high heat capacity and low solar reflectivity. The alteration of the natural land cover due to urbanization causes a change in the

Visionen när områden ska detaljplaneläggas för ny bebyggelse, i centrala delar av städer, är att skapa gaturum med stadsliknande karaktär. Önskan finns om att skapa mötesplatser och ett livfullt område. För att uppfylla denna vision har detaljplaner utformats utan kvartersmark mellan byggnader och allmän plats vilket innebär att husfasaderna går i användningsgräns till den allmänna platsen. FöljdeThe vision when municipalities are planning new areas is to create a feeling of urbanity and create vibrant and safe places. Usually the municipalities have designed the detailed development plan with a space between the public space and the buildings. Lately this place has been removed from many detailed development plans in central urban areas to fulfil the vision of urbanity. It means that balc

Idag vet vi att klimatet håller på att förändras, och vi riskerar fatala konsekvenser. I denna studie undersöks svenska klimataktivister och deras förhållningssätt till sig själva, klimatproblemen och icke-aktivister, samt dynamiken däremellan. Detta genom att intervjua nio stycken klimataktivister. I intervjuerna beskrivs klimatproblemen som å ena sidan att de ekonomiska lagarnas är överordnadeToday, a climate crisis is immanent. In this thesis I have conducted nine semi-structured interviews with Swedish climate activists. I here answer four research questions: 1) how they construct the problem of climate change; 2) how they present the non-activists and their motivations; 3) how they present themselves and their own role; and 4) how strategies and reactions can be understood from the

Det finns olika typer av glas och de som beskrivs i detta arbete är planglas (floatglas) och säkerhetsglas. De säkerhetsglas som behandlas är härdat, värmeförstärkt och laminerat glas. Planglasets och säkerhetsglasens beståndsdelar, tillverkningsprocesser och egenskaper förklaras. I Boverkets byggnadsregler, BBR, finns det olika regler för hur glas får användas i olika typer av byggnader där männ

Barnböcker är en källa som sällan används i historiska undersökningar trots att de har en stor potential att ge kunskap om förställningar som var rådande i den samtid de författades i. Detta gäller inte minst föreställningar om barndomen, vilket gör att barnlitteraturen är en god väg in i barndomens komplexa historia. Nils Holgerssons underbara resa genom Sverige (1906-1907) är numera en klassikerChildren’s literature is an underused source for historical studies even though children’s books have great potential to give us insights into the time in which they were written. This is especially true when it comes to views of children and childhood which makes children’s literature a good way into the complex history of childhood. Nils Holgerssons underbara resa genom Sverige (1906-1907) is a

This thesis seeks to understand current Saudi Arabian political trajectories and recent reform initiatives, in relation to the traditionalist ideological roots and conservative Islamic legitimacy of the state. Methodologically based on a quantitative case study of the ‘Saudi Vision 2030’ reform project, the thesis discusses the limitations of democracy and secularization in relation to the pursuit

The purpose of this thesis is to examine how CSR experienced female directors impact the relationship between CSR and financial performance. This is performed by applying a deductive research approach and analysing panel data with fixed effects regressions. In total, the empirical data consists of 2,065 firm-year observations for 449 unique firms listed on the S&P 500 index during the time per

This paper aims to study the effect that board independence and diversity have on IPO underpricing. It is expected that through signalling, these factors might have a negative relationship with underpricing. Listings between 2015-01-01 - 2018-12-31 on the two Swedish stock exchanges Nasdaq Stockholm and Nasdaq First North are investigated and the final sample consisted of 188 observations. The qua

Arbetstillfredsställelse har under lång tid varit ett omtalat ämne inom forskning och det har visat sig att arbetstillfredsställelse korrelerar med många olika konstrukt, såsom self-efficacy, socialt stöd och stress. Studiens syfte var att undersöka hur mycket self-efficacy, upplevelsen av socialt stöd och stress tillsammans predicerade arbetande personers arbetstillfredsställelse. Syftet var ävenJob satisfaction has long been a popular topic in previous research and it has been shown that job satisfaction correlates with many different constructs such as self- efficacy, social support and stress. Therefore, the study aimed at examine how much employees’ self-efficacy, experience of social support and stress together predicted job satisfaction. The aim was also to examine whether self-effi

There has been little empirical study of the relationship between remittance inflows and economic growth, especially with a focus in Asia and the Pacific (APAC) region. In this paper, this relationship for 23 APAC economies is examined. A panel data set of remittances and financial development indices for the period 1990 – 2017 is set up to explore the impact of financial development on remittance

Long term economic growth leading to development is as much about growing as avoiding spells of considerable negative growth, or shrinking. However, much more attention has been given to understand what makes countries achieve high growth rates than to avoid shrinking. Here we explore empirically a novel approach which proposes that five interrelated dimensions of social capability (inclusion, tra

The integration of migrants' children in host societies has become one of the main challenges for Italy. Schools and educational institutions play a central role in this process as they provide a fundamental basis for human capital accumulation and integration of new migrant generation. In recent years, the exponential growth of Italy's second-generation migrants has increasingly shown the

Det råder en utbredd bostadsbrist i Sverige, 243 av 288 svenska kommuner uppgav 2018 att de har ett stort behov av bostäder. För att lindra detta underskott krävs det att nya bostäder uppförs både med traditionella metoder men även att nya kreativa lösningar implementeras. En sådan kreativ lösning är förtätning i stadskärnor genom påbyggnad på befintliga hus. Denna förtätningslösning är idag dock
