This paper explores the relationship between temporary migration and fertility behaviour in Tajikistan. This research is motivated by the great volume of Tajikistanis who migrate temporarily from high-fertility Tajikistan to low-fertility Russia. Cox proportional hazards survival analysis models are used with a relatively large and representative dataset. The results of this analysis indicate that

The Covid-19 pandemic and climate change are two current crises happening at the same time. Prior research found that both crises have the potential to influence a person’s anxiety levels and mental health in general. The two types of anxiety Covid-19 anxiety and climate anxiety are still largely unexplored, and little is known about their association with each other. This study investigated Covid

During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. In parts of Sweden, however, the most common type of soil is the glacial

Inferring emotions from other people's facial expressions is essential for interpersonal functioning, but not everyone is equally capable. Facets of trait empathy (personal distress and empathic concern) influence emotion perception into opposing directions. Whether situational empathic states are similarly influential has not yet been studied and was the focus of this paper. A 3 (induction) x

Producers in the cardboard and containerboard packaging industry want to, and are sometimes forced to, increase the amount of recycled fibers in packaging, but there is no way to confirm the actual composition of fibers by examining the material optically or chemically. Blockchain technology is often seen as a promising technology for data storage and it is argued that it can help increase transpa

This study examines the 1988 criminalization of personal drug use in Sweden by analyzing the developments in youth drug use between 1971 and 2024 and drug-related mortality between 1969 and 2017. Using a descriptive time-series approach and indexed graphs, it explores how these two indicators developed over time and whether their trajectories reflect the policy’s stated aim of reducing both use an

This thesis examines the scope of the law of State immunity from enforce-ment, with the intention of determining if the frozen assets and reserves of the Central Bank of Russia can be confiscated without implicating State immuni-ty. State immunity from enforcement has its legal basis in customary interna-tional law and is generally understood to protect State property from being subjected to pre-

This project investigates the potential of reclaimed wood waste from the wood industry, with a focus on interlayer sticks (strö), aiming to restore their value and prevent them from being discarded after a single use. Through material exploration and design ideation, the project leads to an exploration of pattern construction, the history of stripes, and the functional and aesthetic benefits of

CCC and DCC are used to estimate the conditional correlation between a non-standard mix of GARCH, GARCH-M and a stochastic volatility model, all assuming Gaussian innovations. After demonstrating the theoretical soundness of this combination, a portfolio of ten assets with diverse return dynamics is constructed. Portfolio performance is evaluated using Value at risk, the Sharpe ratio, maximum draw

Landscapes fill a fundamental function of the human experience. The variance of these landscapes however, are vast, and arguably, so could the human experience of them and the ways they are expressed linguistically be as well. Of the few studies that so far has been conducted on this, none has focused on North America as a whole in a quantitative manner. This study aims to explore what systems lan

Income inequality is typically assumed to be a societal problem. Yet, empirical evidence remains inconclusive on whether inequality reduces individuals’ well-being or not. This study uses data on national-, state-, and city-level inequality measures in Mexico to observe how these relate to changes in self-reported well-being across 12 years. The analysis reveals that the relationship between happi

Utvecklingen av autonoma fartyg (‘MASS’) innebär betydande utmaningar för det befintliga systemet för sjörättsligt ansvar. Culpabaserat ansvar och begreppet vårdslöshet är traditionellt uppbyggda kring bedömningen av mänskligt handlande, beslutsfattande och kontroll. Detta väcker frågor om huruvida vårdslöshet och culpa fortfarande är begreppsmässigt sammanhängande när operativa beslut fattas av aThe development of Maritime Autonomous Surface Ships (‘MASS’) presents significant challenges to the existing framework of maritime liability law. Fault-based liability and the concept of negligence are traditionally structured around the assessment of human conduct, decision-making and control. This raises the question of whether negligence and fault remain conceptually coherent where operational

Supply chain management (SCM) has become more challenging than ever, considering the effect of globalization on organizations as operating through transnational business networks. Conventional supply chains have been facing struggles such as lack of advanced technologies and traceability in operation, which then leads to operational inefficiencies. Blockchain (BC) technology offers a set of featur

Respiratory tract infections (RTIs) are a major global health concern. Several studies indicate that most respiratory bacterial pathogens are capable of asymptomatic colonization and find their primary ecological niche within the nasopharynx of healthy individuals as harmless commensals that form biofilms. However, in response to external factors, such as concomitant virus infections, colonizing b

How do practices of migration, consumption and gender mutually shape each other in contemporary society? In this thesis, I am trying to partly address some aspects of this question by examining the consumption practices of Ukrainian migrant mothers in Sweden. Drawing on conceptual frames of gendered geographies of power and employing a practice theory as a meta-theoretical approach, I conducted fo

G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i

Bumblebees and other pollinators have recently experienced population and diversity declines linked to habitat loss and fragmentation due to land use change. A previous study in Sweden showed a big shift in bumblebee community composition, where the Bombus terrestris complex (B. terrestris, Bombus lucorum) highly increased in relative abundance, but the relative contribution of the two different s

One of the larger changes in society that affected individual’s lives during the 20th century is the increase in divorce rates that happened in almost all industrialized countries. It went from being an uncommon feature reserved for the rich to a prominent part of family-life. The increase occurred against the backdrop of economic growth and the industrialization. This study constructs a data set
