Hur uppfattar svenska elever, från grundskolan till gymnasiet, storlek och skala i rymden? Det ska projektet Storlek och skala, som drivs vid Nationellt Resurscentrum för fysik (NRCF) vid Lunds universitet. Sedan 2020 har data samlats in via en webbenkät som getts ut till lärare och deras elever runt om i Sverige. Studier om elevers uppfattningar om rymden är ett stort område i internationell forThis study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and

Forest carbon sinks are becoming increasingly important as a climate change mitigation tool. To date, New Zealand is the only country that has fully incorporated forestry into its emission trading framework. This study seeks to understand if and how that has impacted forest management practices and carbon sink enhancement. Furthermore, this study seeks to understand to what extent the practices in

This paper studies the impact derivative hedging has on firm value and whether the relationship is affected by differences in cash holdings. We use hand-collected data for 171 Swedish firms from various industries during the period 2016-2021 to examine the relationship. Using a multivariate regression approach with Tobin’s Q as a proxy for firm value, we find that firms using derivatives are assoc

Detta examensarbete handlar om de problem relaterade till kabelskador som uppstår idag i samband med kabelutsättning vid grävarbeten inom järnväg. Kabelutsättning utförs vanligtvis av en underhållsentreprenör, som utförs genom att markera markytan där kabel under marken kan tänkas finnas. Instrument som används för att lokalisera kabel fungerar relativt bra men kan störas av spänningsförande anlägThis thesis addresses the problem related to cable damages that arise today during cable exposure in railway excavation works. Cable exposure is typically carried out by a maintenance contractor, marking the ground surface where underground cables are located. The instruments used for cable localization functions relatively well but can be disrupted by nearby electrical infrastructure. Consequen

In this essay I will examine whether H. P. Lovecraft’s alien species are more evolved and more intelligent than humans. The three races that will be examined are Mi-Go from The whisperer in Darkness (1931), The Deep Ones from The Shadow over Innsmouth (1936), and The Great Race from The Shadow Out of Time (1936). These races will be analyzed with the help of the post-humanistic theory, which focus

Koncessionsmineral är ämnen som är viktiga för samhället, de behövs för att bygga bilar, telefoner, infrastruktur och mycket mer. Ämnena är även viktiga för att verkställa en grön energiomställning och för uppfyllelse av de nationella miljömålen. För att utvinna dessa ämnen behövs någon form av gruvbrytning, vilket kan ske i underjordsgruvor eller dagbrott. Gruvbrytning är en verksamhet som tar stMetals and minerals are prerequisites for a modern and climate-neutral society. Domestic mining facilities are also an essential part of the Swedish national economy. Sweden has a unique bedrock and is one of Europe's largest producers. However, the willingness to invest in the Swedish mining industry has dropped over the last decade. The main reason for this is the complication and uncertaint

Den globala uppvärmningen medför att sannolikheten för extrema värmeböljor ökar i ett framtida klimat. Sommaren 2018 var en ögonöppnare för många i Sverige då den långvariga värmen medförde extrem torka och ett flertal skogsbränder. De mest sårbara i samhället drabbad av värmen, så som äldre, vuxna med kroniska sjukdomar och små barn, och ca 750 fler människor dog än vad som normalt förväntas undeThe summer of 2018 was a reality check for many when several heat waves made the temperature rise above normal in Sweden. Especially in urban areas, where heat can be stored more easily in the building materials, the temperature was extreme due to the creation of urban heat islands. Today these areas can be detected with a tool for mapping urban heat islands. The aim of this study is to examine h

Coral reefs are essential for providing ecosystem services to humans, including coastal protection, nutrition, and income opportunities for coastal communities. However, coral reefs worldwide have suffered severe damage due to anthropogenic factors, leading to their rapid degradation. Thus, next to preventative actions, coral reef restoration efforts are necessary to avoid complete degradation. In

The intellectual property regime within the European Union is one which has a rich and lengthy history, encompassing a wealth of forms of expression. The harmonisation of copyright can be dated to the creation of the Berne Convention for the Protection of Literary and Artistic Works of 1886. Video games, in comparison, only joined the cultural zeitgeist in the mid-20th century. In the pursuing yea

Under den cirka en miljard år gamla Svekonorvegiska orogenesen deformerades den västra randzonen av Fennoskandiska urbergsskölden. Denna händelse ligger till grund för hur sydvästra Skandinaviens berggrund ser ut idag, men det är ännu omdiskuterat hur orogenesen skedde i detalj. Idefjordenterrängen som avgränsas till Östra Segmentet av Mylonitzonen, innehåller sekvenser av metasediment tillhörandeThe approximately 1 Ga old Sveconorwegian orogen occupies the western margin of the Fennoscandian shield and comprise tectonically reworked and metamorphosed rocks. This event accounts for the characteristics of the bedrock in southwest Scandinavia today, but it is still debated how this development took place in detail, and especially if it was a collisional or non-collisional orogeny. The Idefjo

Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. Modern telescopes, both ground- and space-based, like the Very Large Telescope (VLT) or the James Webb Space Telescope (JWST) will drive forward the

This thesis studies the causes of rising household and particularly mortgage debt in Sweden between 1995 and 2020. It aims to contribute to the understanding of institutional factors behind increasing debt, such as policy regulating lending. It undertakes a qualitative analysis of previous literature on household debt, and the Financial Accelerator framework. The Financial Accelerator (Bernanke &a

I syfte att förstå lösningar för nutida optimeringsproblem, ska vi se på det matematiska ramverket för den moderna teorin om variationskalkyl. Variationskalkyl är en gren av matematiken som utvecklades under 1700-talet för att lösa problem gällande fastställning av optimala trajektoria, former och strukturer, givet vissa begränsningar. Dess utveckling pågick parallellt med framsteg inom matematiskCalculus of variations is a branch of mathematics that was developed in the 18th century to solve problems of determining optimal trajectories, shapes and structures subject to constraints. It deals with the minimization of a certain type of integral functional. In the early days of the theory, the smoothness of the functions involved was assumed but, during the following centuries, advances in an

Small, and medium-sized enterprises (SMEs) have recently been identified as high contributors to social and environmental issues globally. Due to this, there has been a high demand for SMEs to become more sustainable, and as such many studies have researched the benefits that accrue to SMEs that implement sustainable practices: serving as a motivation for most SMEs. However, it has not been easy f

Modern consumerism and overconsumption in e-commerce have profound ecological ramifications, necessitating the adoption of pro-environmental behavior. Imagine a world where sustainable choices are seamlessly integrated into our online shopping experience. Nudging is a powerful tool that holds the key to transforming consumer behavior and promoting sustainable online shopping. However, there is a c

The thesis discusses how visual artists negotiate the boundaries between their own creative work and AI-aided work, how they establish boundaries with other artists who use AI, and How the relationship between visual artists and clients is mediated in the market with the rising popularity of AI tools. The study found that most artists negotiate meanings to take a stance and, more often than not, a

Sanctions, as a foreign policy tool, are increasing in popularity and frequency. This study empirically assesses how different types of sanctions imposed by the European Union, United Nations, and the United States affect the sanctioned states’ GDP growth and degree of openness. Moreover, this study aims to address whether the economic costs of sanctions have undergone any notable changes in the c

H.G. Wells’ novella The Time Machine (1895) tells the story of The Time Traveller who travels to the year 802,701. There, he encounters two evolutionary progressions of humanity. One, Morlocks, have been read as representations of Victorian workers and poor, and the other, the Elois, as representations of the aristocracy. The Time Traveller represents the middle class. The novella is often seen as
