While Ellis, Reid, and Kramer’s life history framework is convincing in explaining individual variation in life history strategies, it has certain limitations, which we discuss – drawing notably on the economic theory of fertility choice. In particular, we suggest that ambient cues to extrinsic mortality alone are not sufficient to trigger sustained net fertility decline.
As a crucial tool for enhancing the readability and comprehensibility of geoinformation, automated label placement in mapping applications remains a significant challenge, particularly when generalizing the label placement process for high-density maps, despite the availability of tools such as QGIS-PAL and ArcGIS-Maplex label engine. This study focuses on utilizing deep learning (DL) for road lab
Over the past decade, organic–inorganic hybrid perovskites have revolutionized next-generation semiconductors, driving unprecedented advancements in cost-effective optoelectronics. While lead-based perovskite semiconductors exhibit exceptional optoelectronic properties, their inherent toxicity and vulnerability to environmental degradation remain significant barriers to widespread commerciali
Halide perovskite solar cells (PSCs) have emerged as a transformative photovoltaic technology, achieving unprecedented power conversion efficiencies. However, the development of electron-transport materials (ETMs), particularly organic ETMs, has significantly trailed behind the rapid progress in hole-transport materials (HTMs). Among the organic ETMs, naphthalene diimide (NDI)-based systems stand
In the mid- to late 1970s, the Swedish economy faced a profit squeeze which threatened to hamper investments and the creation of jobs. This engendered a massive debate in the media and among economists and policymakers. This article investigates what I call ‘the politics of profits, the debates around the role of corporate profits in a democratic capitalist society and economy and the policy measu
The reuse of building services, particularly HVAC (Heating, Ventilation, and Air Conditioning) components, remains underexplored in adaptive reuse practices despite their substantial environmental impact and material intensity. This study investigates the feasibility of HVAC component reuse through a mixed-methods approach, combining a structured questionnaire with semi-structured interviews invol
Ung och skuldtyngd ger en djupgående inblick i upplevelsen av att som ung vuxen leva med skuldsättningsproblem - överskuldsättning - i dagens moderna konsumtions- och kreditsamhälle. Under två års tid har forskarna genom upprepade etnografiska intervjuer följt 18 personer mellan 18 och 25 år som är överskuldsatta. Resultaten besvarar frågor som: Hur kommer det sig att unga personer får problem med
Adaptive reuse, the conversion of buildings for new functions, is gaining prominence for its cost-saving and environmental benefits. However, prior research primarily focuses on preserving the building envelope, often overlooking building services such as ventilation, which affect occupant well-being, costs, and environmental performance. This study explores a novel adaptive reuse approach by reus
The radioactive noble gas radon (222Rn) is a suitable tracer for atmospheric transport and mixing processes that can be used to evaluate and calibrate atmospheric transport models or to estimate greenhouse gas (GHG) emissions using the so-called radon tracer method (RTM). However, these applications require reliable estimates of the 222Rn fluxes from the soil. This study evaluates two process-base
Vitamin A deficiency (VAD) remains a severe health issue in sub-Saharan Africa, causing blindness, illness, and child mortality. In Mozambique, about 69% of children under five are affected, highlighting the short-term impact and donor dependence of supplementation programs. Mangoes (Mangifera indica L.), rich in provitamin A carotenoids, offer a sustainable, food-based strategy to reduce VAD, but
Wood used in outdoor construction is consistently subjected to wetting by precipitation. High levels of moisture content, especially if sustained over long periods, promote fungal decay and structural degradation. Predicting temporal variation of moisture content in wood exposed to rain is essential for durability assessment, and simple fit-for-purpose numerical approaches have been developed for
The urgent need to address climate change and pollution prompts societies worldwide to adopt carbon neutral energy and electrification. To facilitate this, a range of technologies and policies will be needed. Alternatives to traditional power grid reinforcement, such as grid-enhancing technologies and system automation, are particularly attractive due to their potentially low cost and fast deploym
This paper sets out to discuss the relevance of the concept of the ”social help state” (socialhjälpstaten) within the framework of Swedish historiography by focusing on the organization of poor relief in Gothenburg between 1890 and 1920. Coined by Norwegian historian Anne Lise Seip in 1984, the term socialhjälpstaten has been used extensively in the study of early welfare institutions and provisio
