Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change. Individuals involved in these problems are generally considered to have two options: contribute toward public solutions such as global warming mitigation or free ride. However, many collective action problems today involve a third option of investing in a “private solu

This doctoral thesis investigates mediaeval earthenware production, distribution and consumption based on material from Lund, Sweden, moving beyond simple technological shifts to explore the interplay of material factors, social practices, and economic influences. It presents a typology of hard greyware, redware and glazed redware, as well as the chemical analysis of circa 400 samples. The study a

It is now widely accepted that the vast majority of inhabitants of cities in developing countries have to be involved in the construction of their houses if they are to become home-owners. During the construction process, most households will make payments for land, construction materials and skilled labour. This chapter analyses the different ways in which households finance these payments and fo

In Africa, young people are engaging with a globalised world of flows and movements but are coming of age in environments characterised by uncertainty, economic hardship and unemployment. Drawing upon research conducted in Madina, a suburb of Accra, a social navigation perspective is adopted to explore young people's everyday mobility and their aspirations for future mobility. By drawing attention

Jag undersöker den ideala krigar-mannen i två av Gamla testamentets profetböcker: Jesaja och Jeremia. Här beskrivs han som misslyckad och sårbar och i metaforer liknas han till exempel vid en kvinna som föder barn. Under perioden för böckernas tillkomst inträffade en katastrof för folket i Juda, den babyloniska exilen innebar att landet erövrades av stormakten Babylonien och att delar av folket tThis book explores how the prophets Isaiah and Jeremiah depict warriors as vulnerable. In the oracle sections of these prophetic books, vivid imagery shows the warriors failing—not only in their duties as mighty men—but also in living up to the expectations of militarised masculinity. They are presented through imagery of cowardice, weakness, pain, and fear and are often portrayed as women, partic

Who benefited from agricultural commercialization in colonial Africa? Using social tables for three African economies, we identify a small group of rural capitalists who captured disproportionate gains. We demonstrate how their strategies of accumulation varied across contexts and shaped divergent and often unequal development trajectories.

Non-invasive MRI is widely used to assess and monitor ischemic stroke, yet conventional approaches often lack sensitivity to subtle microstructural changes and struggle to evaluate tissue viability across lesion, penumbra, and distal regions. In this study, frequency dependent diffusion tensor distribution imaging (ωDTD) was combined with clustering of diffusion tensor distributions D(ω) and multi

Although it is a fundamental concept in global health and development, soli-darity is surprisingly hard to capture. This essay first discusses characteris-tics of solidarity, including perceived and real tensions between self-interest and solidarity in international aid. In doing so, it draws upon illustrative ex-amples from Sweden’s aid history, as well as international vaccine solidarity during

In this study, we have investigated the dynamic behavior of colloidal rods within their isotropic phase, employing multispeckle ultrasmall-angle x-ray photon correlation spectroscopy (UA-XPCS) focusing on the understanding of the interplay between structure and dynamics at the nearest-neighbor length scale. While prior research has primarily focused on the structural aspects, our work addresses th

Using ultra-broadband transient terahertz (THz) spectroscopy, complemented by transient absorption (TA) and photoluminescence (PL) measurements, we directly track the generation and relaxation of photoexcited hot carriers, as well as the ultrafast formation of excitons in the transition metal phosphorus trichalcogenide NiPS3, with a temporal resolution of sub-100 fs. A subset of excitons exhibits

PURPOSE OF REVIEW: This review aims to give an overview of recent advances in the clinical management of children <18 years of age with end-stage pulmonary hypertension refractory to conventional medical therapy.RECENT FINDINGS/SUMMARY: The increased awareness and characterization of pediatric pulmonary vascular disease has amounted more data toward creating an accurate, and comprehensive, risk pr

The proline-rich domain (PRD) of the tumor suppressor p53 plays a central role in modulating conformational dynamics and molecular interactions, yet its intrinsic structural behavior remains incompletely understood. Here, we combine extensive all-atom molecular dynamics simulations with biophysical validation to characterize the conformational ensemble of the p53 PRD. The domain behaves as an intr

This thesis investigates the quantum Mpemba effect, where an initially hotter system cools down faster than an initially colder one. This was demonstrated in a qubit system coupled to two environments. A thermal state is chosen as the initial state and then left to freely equilibrate. It was shown that the initial thermal state can be chosen in a way to accelerate the resulting relaxation process.

Lipid nanoparticles (LNPs) have emerged as an efficient platform for mRNA delivery, in which ionisable lipids play a central role in intracellular uptake and endosomal escape. In this study, the influence of different ionisable lipids on cellular uptake, endosomal damages and mRNA release kinetics was investigated to identify promising LNP compositions for effective mRNA delivery. Dose-dependent L

This project addresses the challenge of designing for permanence within a heavily gentrified and tourist-driven environment. It responds directly to local housing needs while integrating small-scale tourism and establishing clear spatial boundaries to safeguard local biodiversity. While housing constitutes the central focus of the proposal, the project also argues that permanence cannot be secur
