This paper focuses on particular immigrant groups, examining the integration extent between the US-born whites and first- and second generation immigrants during the Age of Mass Migration. From empirical evidence in this paper, I find that immigrants suffered an income penalty in the labor market, and second generation were more integrated into the US labor market. Immigrants with greater cult

EU:s Green Deal och Sveriges ambitiösa mål om klimatneutralitet år 2045 har satt fart på omställning till ett fossilneutralt samhälle. En nyckelkomponent för denna transformation är den gröna vätgasen. Detta är en lovande energibärare som har potential att revolutionera vårt sätt att använda resurser och leda oss mot en mer hållbar framtid. Tillämpningen av denna växer fram naturligt i regioner meGreen hydrogen is one of the key solutions for industrial decarbonization in sectors that cannot be easily electrified, however, the technology faces profitability challenges. The European Union mitigates these issues through various grants. This study, in collaboration with Kraftringen, examines an investment in a hydrogen system to address these challenges. The major aims include understanding e

En medvetenhet och högre krav på naturliga ingredienser hos konsumenter får företag att försöka minska på e-nummer och tillsatser i sina produkter. För att ändra befintliga recept och ta bort tillsatser krävs det undersökningar och tester. I denna studie undersöks möjligheten att ta bort ett av två konserveringsmedel i en befintlig produkt utan att riskera den mikrobiella säkerheten. Det är mång

Globala servicenivåmål och lagerkrav i distributionssystemet hos en tillverkare av industrigods Hur kan ett industriföretag se till att deras produkter finns tillgängliga när och där kunderna behöver dem? Tänk att en båttillverkare i Australien behöver en specifik båtmotor och de vill inte vänta i månader på att motorn ska levereras från Sverige. Det är då lageroptimering kommer in i bilden. GenoTitle: Global service level targets and stock requirements in the distribution system of a manufacturer of industrial goods Authors: Nils Holmqvist & Hugo Lundholm Supervisors: Johan Marklund, LTH | Lisa Thorsell, Volvo Penta Background: Volvo Penta is facing challenges in inventory management of marine engines in remote markets.

The release of carbon dioxide (CO2) from inland waters plays an important role in the global carbon cycle. Yet, there are uncertainties related to estimating riverine CO2 evasion (FCO2), especially in data scarce regions such as the Tibetan Plateau. It is unclear how global change in the form of climate warming and anthropogenic disturbance affects emissions. This study reports annual CO2 fluxes a

This study examines various risks associated with the use of artificial intelligence (AI), which have become increasingly relevant as the technology rapidly develops and integrates into society. The risks have been categorized into six main areas: technological, data- and analytical, informational and communicational, economic, social, ethical and legal and regulatory. These areas include challeng

As a response to a changing climate and a growing population that increases the current unsustainable, industrialisation of agriculture, sustainable agricultural practices have gained interest globally. Regenerative agriculture was first mentioned in the 1980s but didn’t gain interest until recently. The research around regenerative agriculture is limited, especially concerning the recent growing
