Astronomins vetenskapliga utveckling kommer idag främst från den information som kan erhållas via ljusstrålning från teleskop. Det viktigaste är teleskopet Gaia, som är ett av de mest ambitiösa rymdprojekt som människan någonsin har genomfört. Det kartlägger över en miljard stjärnor med position, avstånd och rörelse. Genom Gaias observationer skapas den första realistiska bilden av hur vår galax, The scientific development of astronomy today mainly comes from the information that can be obtained via electromagnetic radiation. Today, the Gaia optical telescope is one of the most ambitious space projects man has ever completed. Another optical telescope LSST is designed to complement Gaia. In about 15 years it will also be possible to measure gravitational waves with the telescope LISA, whic

Det här examensarbetet undersöker vilka faktorer som påverkar användandet av privat bildelning och om det är önskvärt med ett ökat användande av konceptet. Många anser att utöver att bidra till förbättringar inom delningsekonomi kan konceptet också leda till ett mer hållbart samhälle. Metoden i examensarbetet består av två intervjuer och en enkätundersökning. Resultatet ger en djupare förståelse fThis thesis analyzes what factors influence the use of private carsharing and if it would be desirable with an increased use. Many claim that, in addition to contributing positively to the sharing economy, the concept can also contribute to a more sustainable society. The methods used in this thesis contained two interviews and one survey. The survey was designed based on the model Theory of plann

The products produced in rich countries are very different from the products produced in poor countries. Why? Unreliable electricity is often cited as one of the main challenges facing industrial production in less developed economies. In this paper, I connect these two observations by linking interruptions in the production environment to the sophistication of the production output. Using a data

Biogas istället för diesel i lastbilarna - Varför inte? Det är bråttom att minska utsläppen av växthusgaser i samhället om vi ska kunna motverka klimatförändringarna och undvika de allvarliga konsekvenser som mänskligheten och ekosystem riskerar att drabbas av. En stor utmaning i Sverige är att byta ut dieseln i alla lastbilar som rullar på våra vägar. Kanske kan biogas vara den klimatsmarta lösnIn order to counteract the ongoing climate change, fossil fuels must be replaced with renewable alternatives in all sectors of society. The transport system is one of Sweden’s most important fossil dependent branches to redirect in this regard. Research suggests that biogas is a renewable alternative that in comparison with other biofuels seem to have a substantial potential and environmental adva

The purpose of this study is to investigate the effect of ESG ratings on firm’s credit ratings for real estate investment trusts in the USA. Through a quantitative research methodology, a panel data regression analysis is used in order to examine the effect of ESG rating on firms’ credit ratings. The sample used in our study consists of a set of unbalanced panel data consisting of 3,470 firm-month

Sea surface temperature and salinity are important variables for understanding many ocean and climate processes. They can be measured both by in situ sensors and satellite remote sensing, each method with its own advantages and disadvantages. Satellite data provides unmatched spatial and temporal coverage on a global scale, but is limited by its spatial resolution which cannot always resolve varia

Abstract of chapter 1 For n >= 2 the number of mixing n-step subshifts of finite type (sft) over the alphabet {0, 1} is proven to be at least 15/16 times the number of transitive n-step sfts. A conjecture assumes the latter to be at least 2^(3*2^(n-1)-n). Abstract of chapter 2 The alternating colouring function is defined. Strings over the alphabet {0, 1} are divided in colourable and non-colouraImagine an of characters A and B. Such can be thought of as a paper strip with As and Bs written on it, one end of which one holds in the hand while the other stretches over the horizon without ever ending. Or as a calculator that displays a new character each second. Or as a printer with an infinite amount of paper and ink that unfortunately only prints As and Bs. In contrast to infinite strings

EU:s statsstödsregler är en del av EU-rätten som har haft stor inflytelse i konkurrenspolitiken bland medlemsländerna. Sverige har under sina 25 års medlemskap inom EU har påverkats och det berör dessutom kommunernas handlingsmöjligheter med att sälja offentliga markområden eller fastigheter till privata aktörer. Denna uppsats kommer att fokusera sig på otillåtna kommunala överlåtelser som anses sEU’s State Aid rules are a part of the EU law that have had great influence in the competition politics amongst the member states of the EU. Sweden has been highly affected by these rules during its 25 years membership in the EU, and it is affecting the ability for the municipalities to sell public land or buildings to private actors. This thesis is going to mainly focus on the unauthorized transf

Media shapes the public´s perceptions of social problems and how we understand the people affected by them. This study investigates the shaping of dual diagnosis, a concept that refers to the co-occurrence of a mental illness and substance use, a phenomena that has gained increased prominence in the last decades. While those suffering from dual diagnosis rarely have their voices heard in research,

The purpose of this bachelor thesis is to examine posts in the facebook group“Försäkringskassanupproret!” and it’s discontent with the Swedish Social Insurance Agencyas a part in a larger critique of the welfare state and its institutions. To do this we developed atheoretical framework out of the literature surrounding grievance and framing through whichwe analyzed our research material. The mater

Bakgrund och problemdiskussion: Överkonsumtion är ett av alla hållbarhetsproblem i dagens samhälle. I och med detta har återbruk blivit mer efterfrågat och konsumtion av begagnade produkter och reparationsservice ökar. I samband med denna trend blir det populärt för företag att implementera cirkulära affärsmodeller. I affärsmodeller syns de logistiska funktionerna, där ett logistiskt bakåtflöde ka

Hypervelocity stars, på svenska hyperhastighetsstjärnor, är stjärnor som observerats med så hög hastighet att de kan lämna vår galax, Vintergatan. Den första hyperhastighetsstjärnan upptäcktes av R. Brown m. fl. (2005), och sedan dess har många fler upptäckts. J. G.Hills presenterade (1988) en teori om att hyperhastighetsstjärnor härstammar från binära stjärnor (två stjärnor som kretsar varandra) In this thesis, I investigate if the binaries that are being tidally disrupted by means of the Hills mechanism, producing hypervelocity stars, could have been transported to the galactic centre by two-body scattering. To survive a scattering event, the binary must be hard, meaning that the binding energy of the binary is higher than the kinetic energy of the collider. If the binary is soft, the bi

Vind, sol och en hel del dynga Innan den sydafrikanska dyngbaggen Kheper lamarcki kan kasta sig över sin gourmetmåltid måste den ta sig bort från dynghögen och den hastigt ökande konkurrensen. Det mest effektiva sättet att åstadkomma detta på är att backa i en rak linje. Hur lyckas man med detta om man är en dyngbagge? Studier har visat att dessa baggar har förmågan att utnyttja himlavalvets olikOnce the South African dung beetle Kheper lamarcki has constructed its ball of dung, it strives to escape the competition at the dung pile and locate soft ground to dig down. The most efficient way to do this is to move away along a straight path. One way to achieve this is by using celestial cues as orientation references. However, when these cues fail to provide sufficient directional informatio

The Convention of the Rights of the Child has become Swedish law as of January 1st 2020. The convention raises every childs’ right to development, of which spiritual development is one part. The matter of spirituality and existential questions has had a marginalized role in Swedish research. The interest is however increasing. The poor mental health amongst children and young people in Sweden is,

Purpose: This study aims to explore the phenomenon of social influence in driving environmentally friendly tourist behaviors. Methodology: To obtain deep and diverse insights about the phenomenon, 20 semi-structured interviews were conducted with respondents representing 13 nationalities. Results: This study revealed that contemporary tourists obtain two conflicting messages from their social en

This thesis examines the resistance created towards the prospects of a mine in the agricultural countryside of Skåne, Sweden. A growing discourse in Swedish media emphasizes mineral extraction as a vital part of a green future due to minerals’ importance for promotion of new modes of energy. At the same time, a resistance has been mobilized against such test drilling in Skåne. Based on anthropolog

Studier visar på att det finns bristfällig forskning om arbetsterapeuters arbete med sexuell hälsa. Syftet: Att undersöka arbetsterapeuters arbete med sexuell hälsa hos individer med intellektuell funktionsnedsättning inom daglig verksamhet och vuxenhabilitering. Metod: Kvantitativ enkätstudie där 30 stycken arbetsterapeuter rekryterades via icke-slumpmässigt bekvämlighetsurval och snöbollsurval. Studies show that there is insufficient research on occupational therapists (OT) work on sexual health. Purpose: Investigate OT’s work on sexual health with individuals with intellectual disabilities in day-centres and adult habilitation. Method: A quantitative survey study where 30 OT’s were recruited via nonrandom convenience selection and snowball selection. Quantitative data were analyzed with

The interest around blockchain technology (BT) has spread for the last decade from academia and industry. Meanwhile, there is a lack of studies on the acceptance and use of blockchain within the Nordic countries. This research provides an exploration of blockchain acceptance and use combined with the identification of factors generating value through this technology. We highlight factors that infl

Idag konsumeras det som aldrig förr, samtidigt som hållbarhetsfrågan tar allt större utrymme i debatten kring konsumtion. Det har lett till att konsumenten söker efter andra konsumtionsalternativ, ur vilket fenomenet delningsekonomin har växt fram. Delningsekonomin har i många fall betraktats som ett optimistiskt konsumtionsalternativ, eftersom det för med sig mindre klimatpåverkan än den traditio

Aim: This thesis aims to develop a deeper understanding of how junior and senior preschool teachers engage in knowledge sharing and learning in a public sector organisation as well as how their knowledge sharing and learning behaviour is being challenged. Literature Review: Our literature review focuses on knowledge and knowledge sharing and relates it specifically to the public sector which corre
