The Meaning and Function of Twelve-Step Mutual-Help Groups During Recovery: A 10-Year Qualitative Follow-Up of Persons Treated for Substance Use Problems in Sweden

Background: Twelve-step treatment for substance use problems is a commonly employed intervention in both international and Swedish contexts. An advantage of twelve-step treatment is the possibility of continuing support for the recovery process through participation in mutual-hel...

The integrated benthic silicate flux in the Baltic Sea suggests a major land- or freshwater-derived reactive silicon source

Abstract. Coastal marine environments are hot spots in the global marine silicon (Si) cycle. Dissolved silicate (DSi) is an essential macronutrient for diatoms, which often dominate primary productivity in temporal coastal seas and constitute a key food source for grazers. Even t...

The Evolution of Low-ionization Electron Densities in Galaxies across Cosmic Epochs

Abstract We investigate the low-ionization electron density in the interstellar medium (ISM) of galaxies across 0 < z < 8, derived with the [O ii ] λλ 3727, 3730 and [S ii ] λλ 6718, 6733 doublets, using both deep JWST/NIRCam/grism and NIRSpec/MSA spectroscopy. Along with ancilla...

EXTENDING CONCEPTUAL COMPLETENESS VIA VIRTUAL ULTRACATEGORIES

Abstract We introduce the notion of virtual ultracategory. From a topological point of view, this notion can be seen as a categorification of relational β $\beta $ beta -modules. From a categorical point of view, virtual ultracategories generalize ultracategories in the same way...

At peace with results: Navigating results in Swedish peacebuilding support

Abstract Motivation This study contributes to the literature on the conditions under which results‐based management (RBM) practices enhance or undermine development policy implementation, and research on how aid bureaucrats respond to competing institutional demands. Purpose The...

Evaluating Bottom‐Up Effects of Cruciferous Cultivars to Optimise Mass‐Rearing and Fitness of the Parasitoid Diadegma insulare

ABSTRACT The diamondback moth, Plutella xylostella (L.) (Plutellidae: Lepidoptera), is one of the major pests of cruciferous vegetables. To control this notorious pest, the caterpillar parasitoid Diadegma insulare (Cresson) (Ichneumonidae: Hymenoptera) is the most used biocontrol...

Doing Normality and Vulnerability: Retrospective Narratives of Early Substance Use in Sweden

Early substance use is commonly framed as a risk factor for later problems, yet less is known about how individuals retrospectively interpret and make sense of these early experiences in relation to their own substance use problems. This article explores how adults who have previ...

A large-scale pipeline for LLM-assisted corpus annotation

Abstract As natural language corpora expand at an unprecedented rate, manual annotation remains a significant methodological bottleneck in corpus linguistic work. We address this challenge by presenting a scalable pipeline for automating grammatical annotation using large languag...

Petroglyphs as petrofacts? Exploring the visibility and physicality of lines, furrows, and cavities in Bronze Age rock art

Abstract This text concerns tangible and sensory aspects of petroglyph production with a primary focus on south Scandinavian Bronze Age rock art. The core of the study is based on an experimental trial of making a cupmark, a circle motif, and a shallow boat motif on a small grani...

Social environment predicts alarm calling in Eurasian magpies

Abstract Animals in dangerous situations often use alarm calls to warn others. Variation in this behaviour across different social settings can serve to answer long-standing questions about the evolution of costly cooperative actions, since warned conspecifics may yield kin-selec...

Tiny Pores, Big Stories: Perforating MXenes for Through-Sheet Transport in Energy and Environmental Applications

Conspectus Transport remains a central bottleneck limiting the practical performance of MXene electrodes and membranes. Although MXenes possess metallic conductivity, hydrophilicity, and rich surface chemistry, their two-dimensional (2D) layered architecture imposes barriers to i...

Spathology: The Birth of Spatial Pathology as a Discipline

Pathology has always been a spatial science: for more than 150 years, diagnosis has rested on reading the architecture of cells and tissues. Three technological streams are now converging on this founding principle. Spatially resolved omics can measure thousands of transcripts an...

Not simply a decline: gendered changes in students’ intrinsic motivation towards mathematics

Abstract This study examines one-year changes in students’ intrinsic motivational orientation towards mathematics and whether these changes are gendered. Drawing on Swedish data from the TIMSS 2023 Longitudinal Study, we analysed two student cohorts, followed from Grade 4 to Grad...

Exploring grade 5–8 novice science teachers’ PCK development for socioscientific issues-based teaching

Abstract In recent decades, socioscientific issues (SSI) like climate change, genetically modified foods, and COVID-19 pandemic-related issues have commonly been seen in news media debates, and SSI-related research has been one of the main research trends in science education. Ho...

Drivers governing the seasonality of new particle formation in the Arctic

New particle formation (NPF) is the phenomenon wherein gaseous precursors form critical clusters of barely a few nanometres in diameter, after which, under favourable conditions, these particles can grow to climate-relevant sizes. Here we present measurements from 2022 to 2024 of...

Biotic and abiotic drivers of ecosystem functioning differ between a temperate and a tropical region

Any single ecosystem will provide many ecosystem functions. Yet, we lack large‐scale, systematic studies of how abiotic factors can directly or indirectly – via effects on biodiversity – drive ecosystem functioning. In this study, we assessed the impact of climate, landscape and...

Universal compactified Jacobians: cohomological invariance and boundary combinatorics

Abstract Pagani and Tommasi have introduced a class of smoothable fine compactified Jacobians $$\overline{\mathcal {J}}_{g,n}^{\,d}(\sigma )\rightarrow \overline{\mathcal {M}}_{g,n}$$ J ¯ g , n d ( σ ) → M ¯ g , n over the moduli space of stable curves, depending nontrivially on...

Ten New Insights in Climate Science 2026 [preprint]

ABSTRACT Building on an open call for expert input, this annual synthesis presents ten recent research advances with high policy relevance. These include Earth’s increasing energy imbalance and its relationship with ocean heat content (Insight 1); ice-mass loss and related sea-le...

Theorizing Cross‐Boundary Strategizing as Situated in Multilayered Supply Chains: A Strategy‐as‐Practice Approach to Supply Chain Management

ABSTRACT Supply chain strategy is increasingly recognized as a multilayered phenomenon, with firms strategizing not only within their own boundaries but across supply chain tiers, jurisdictions, and wider regulatory and ecological systems. Yet most existing supply chain managemen...

Reproducibility of Colloidal Lignin Particle Preparation: An Interlaboratory Evaluation

Abstract The reproducibility of the preparation of colloidal lignin particles (CLPs) was evaluated through a coordinated interlaboratory study involving seven independent research groups from around the world. The objective was to assess the robustness of the anti-solvent precipi...
