Bland de mest kraftfulla händelser som människor har observerat är gammablixtar. Blixtarna är korta utbrott av gammastråalning som ibland dyker upp i rymden. Forskare har länge misstänkt att kollisioner mellan neutronstjärnor ligger bakom en kategori av blixtar, de korta gammablixtarna. För några år sedan bekräftades forskarnas misstankar. De kunde då, med det nya LIGO-observatoriet, observera graShort gamma-ray bursts are often observed at large spatial offsets from their host galaxies. Neutron star mergers in double neutron star binaries have also recently been confirmed as a progenitor of short gamma-ray bursts (Abbott et al. 2017). We attempt to constrain uncertainties in the evolution of burst-producing neutron star binaries by generating a distribution of burst offsets from the neutr

Gender equality is now more than ever a highly discussed topic within many different aspects of society. Also, being an entrepreneur is becoming increasingly more accessible and popular as a choice of occupation. This study aims to analyze the potential relationship between gender equality in entrepreneurship and the outcome on economic growth. By developing an index which ranks American states’ d

Människan och hampan (Cannabis sativa) har en gemensam historia som går långt bak i tiden, denna historia är dock omgiven av kontroverser. Idag är Cannabis mest känt för sina psykoaktiva egenskaper och narkotika klassificering i många länder, men hampa har historiskt sett främst odlats för fiberproduktion. Denna studie undersöker historisk hampaodling i Europa och är baserad på redan publicerade dHumans and hemp (Cannabis sativa) have an ancient relationship, dating back to the beginning of recorded history. Nevertheless, controversy surrounds the antiquity of the plant. Today Cannabis is probably most famous for its psychoactive properties and illicit status in numerous countries, however hemp has primarily been cultivated as a fibre crop in the past. This study examines the European hist

In this paper I examine what I call the ‘gnomic expression’, i.e. a statement of a general truth with regards to the human condition, as it is manifested in the Iliad, the Odyssey and Beowulf. A general introduction is first given to gnomic poetry in the Greek and Anglosaxon traditions in order to put the main analysis into its historical and literary context. The analysis is then presented in fiv

Som sångerska har jag sjungt en hel del i kör, och på grund av det har jag fått möte flertalet körledare. Dessa körledare har olika kunskaper om rösten, och har lärt mig om rösten på olika sätt. Ibland var det felaktig information som delgavs, ibland var det ordvalen som kunde varit bättre, och ibland hade körledaren full koll. Den kunskap som körledarna förmedlar formar sedan koristerna, och då sAs a singer I have sung a lot in choir, and because of that I have met many choir leaders. These choir leaders had different knowledge of the voice, and different ways to approach vocal technique. Sometimes the information was incorrect, sometimes it was the shortage in words, and sometimes the choir leader had complete control. The way the choir leader gives instructions in vocal technique affect

The study explores how USA, as a liberal democracy, justifies actions that can be described as extra-judicial targeted killings. The study is based on a three-case study of the Clinton, W. Bush and Obama administrations. The frame theory is used to categories and analyze the official statements, to get an understanding of how the different presidential administrations with the use of words are try

We develop methods for estimation, inference and optimization of causal effects from observational data with continuous treatments. We present a counterfactual prediction method based on the potential outcomes framework that estimates the expected value of a potential outcome given a treatment level and confounders. We show that the method identifies the average generalized treatment effect (AGTE)

När jag under min utbildning varit ute på praktik och vikarierat har jag flera gånger stött på begreppet konstnärligt uttryck. Jag har alltid tyckt det var svårt att förstå exakt vad ett konstnärligt uttryck innebär. Därför föddes idén till denna studie om att prata med verksamma sånglärare inom gymnasieskolan och ta reda på mer om hur de jobbar med det konstnärliga uttrycket. Syftet med denna stuWhen I have done internships and worked as a substitute during my education I have come across the term artistic expression several times. I have always had a hard time understanding exactly what an artistic expression means. That is where I got the idea to talk with active singing teachers in upper secondary school to find out more about how they work with the artistic expression. The purpose wit

The riparian countries of Lake Chad River Basin – Nigeria, Niger, Cameroon and Chad – suffer from environmental degradation as the lakes surface water has decreased with 90 percent since the 1960’s. This has put pressure on the population around the lake as the livelihood for many of them is dependent of the lake’s water. The area has during the last decade also been characterized by increased vio

A decade has almost passed since former dictator Muammar al-Gaddafi was toppled after an 8-month long civil war in Libya and the outlook of democratization looked bright for the Northern African state. This process turned out to be more than complicated and eventually led the country back to violent hostilities. In this study the parliamentary election of 2012 is studied to see if the sequencing o

This study is an evaluation of the peacebuilding missions in Afghanistan, made by the United Nations, in relation to policies of sustainable development. The theoretical framework is borrowed from Peace Ecology, suggesting a foundation for peacebuilding where mankind is reintegrated into nature. It further stresses a need for the return of the commons and a development of local and community-based

In this thesis, the power dynamics underpinning the relationship between USAIDfunded humanitarian organizations and U.S governmental agencies – in relation to the Global War on Terror (GWoT) - are critically investigated. To this end, a Foucauldian lens of ’disciplinary power’ is utilized to uncover U.S governmental agencies’ employment of disciplinary practices categorized as surveillance, correc

This study aims to understand president Duterte’s ’war on drugs’ through human security theory. In order to achieve an analytical framework for human security, two of its subcategories have been used as a theoretical entrance: personal and political security. The study consists of a single case study with an understanding approach to the phenomenon of the Philippine drug war through human security

Youth present either a risk or a great opportunity for change. Traditionally youth have been perceived in binary terms of either as victim of wars or as threats to peace and security. The UNSCR 2250 on Youth, Peace and Security presents a shift in the perception of young people, now regarding them as agents of peace and security. This thesis will shed light on young Palestinians through a case stu

This study investigates the morality of securitization. More specifically, it examines the possibility of a just securitization. Using Just Securitization Theory, developed by Rita Floyd, it analyzes the morality of a case of securitization. The selected case for testing Just Securitization Theory is the U.S securitization of bioterrorism after the incidents of 9/11 and the anthrax attacks in the

Terrorism seems to have changed character in the wake of globalization and the modern world. The unclear magnitude of these changes has given rise to a debate on whether terrorism today can be labeled as ‘new’. This thesis examines how the terrorist organization Hamas should be defined in this debate on the character of contemporary terrorism. The study is carried out as a theory-testing case stud

Att skriva musik är något som har varit närvarande under hela mitt liv. Jag skrev min första låt när jag var åtta år och efter det har musikskapande varit en stor del av mitt musicerande. Att jobba med barn i de lägre åldrarna har också varit ett arbete som lockat mig. Jag har dock känt att jag saknar kunskap om hur barn i den åldern tar till sig musik och funderat över om sättet vi musicerar med Writing music has always been an important part of my life. I wrote my first song when I was eight years old and since then, making music has been a huge part of me as a musician. Working with children has also been something that I have found interesting but I have always felt like I did not have sufficient knowledge to do so. I have also wondered if the current way to make music for young childr
