Achievement goal orientation profiles in high-performance soccer players in relation to their personality structures

Abstract Background Among the various determinants of performance in soccer, motivational factors play a significant role. Personality traits, among other factors, can have an important impact on shaping motivation in sports. Therefore, the aim of our study was to identify more c...

Earth-Abundant Manganese Catalysts for Dehydrogenative Coupling of Alcohols and Silanols with Hydrosilanes

Abstract The development of catalysts and/or simple systems based on earth-abundant metals that enable the selective synthesis of siloxanes and alkoxysilanes while generating valuable hydrogen as the sole byproduct remains a major challenge in catalysis. Herein, we report a mild,...

UV and solar radiation effects on natural and anthropogenic carbonates studied by Electron Spin Resonance

This is the author-submitted, pre-peer-review version of a manuscript submitted to Geochronometria for the MACh 2026 conference proceedings. The manuscript is currently under peer review. Light exposure in trapped-charge dating is commonly considered primarily as a bleaching proc...

From Institutional Neutrality to Professional Identity: Conscientious Objection and the Regulation of Religious Presence in the Medical Professions

The article analyses the conscience clause in the medical professions as a manifestation of a broader process of regulating the presence of religion in professional practice. Its point of departure is the Polish cooperative model of state–religion relations, in which institutiona...

Cascade Remodeling through Late-Stage Electrophilic Fluorination in a Bis-Spiroketal Framework

Abstract Cascade reactions efficiently generate molecular complexity but are often incompatible with the late-stage diversification of highly functionalized natural products due to competing degradation pathways. Herein, we demonstrate that electrophilic fluorination can serve as...

Radiocarbon dating of mortars: A case study from ancient village Dūré

Abstract The absolute chronology of historical structures in regions with limited documentary evidence or organic remains presents a significant challenge for archaeologists and historians. Radiocarbon dating of anthropogenic carbonates, such as mortar binders, offers a potential...

Adaptive Re-Screening and Pair-Screened Joint Rescue for Scalable Stepwise Selection in Cross-Classified Linear Mixed Models

Stepwise fixed-effect selection in complex linear mixed models is expensive because each candidate can require the re-estimation of variance components. Permanent pruning lowers this cost but can discard predictors that become relevant after other terms enter. We propose adaptive...

Photographing the Greater Poland Army: Kazimierz Greger and the Visual Documentation of Military Formation, 1918–1919

This article examines the photographic documentation of the Greater Poland Uprising (1918–1919) and the formation of the Greater Poland Army by Kazimierz August Greger (1887–1967), a photographer trained in Germany and active in Poznań. Based on archival research and an analysis...

gasome

I proposed the term "gasocrinology" (1-3). To the best of my knowledge, unlike the terms "proteome" and "transcriptome," there are no similar terms specifically for gases. I propose defining "gasome" as the complete set of gases synthesized by a particular cell. This definition c...

Photoredox/Cobalt-Catalyzed Cascade Rearrangement-Cyclization of Alkene

A photoredox/cobalt-catalyzed sequential rearrangement-cyclization of unactivated alkenes is reported. 1,1diarylalkenes bearing tethered nucleophiles undergo a selective 1,2-aryl migration, initiated by metal-hydride hydrogen atom transfer and radical-polar crossover, and followe...

Between caution and adaptation. Artificial intelligence in Polish social work practice

This article examines how Polish social work practitioners perceive artificial intelligence (AI), the extent of its adoption, and the hopes and concerns linked to its use. In December 2025, a nationwide Computer-Assisted Web Interview (CAWI) survey was conducted with 1,243 social...

Ultrasound-Induced Mechanoluminescence: From Remote Activation to Emerging Photonic and Biomedical Applications

Abstract Mechanoluminescence (ML) has traditionally been understood as a mechanically induced light emission phenomenon activated by direct contact stimuli such as fracture, deformation, or friction. The emergence of ultrasound (US) as a remote, noncontact mechanical excitation s...

Behind the Bricks and under the Roof Tiles: Stamped Roman Building Ceramics from the Legionary Camp at Novae in Light of Historical and Physico-Chemical Analysis

Abstract The article is devoted to stamped ceramic building material from the legionary fortress at Novae in Lower Moesia. It combines historical and epigraphic analysis with physicochemical analyses of selected bricks and roof tiles. The aim of the study was to assess whether la...

Structural and configurational analyses of GenAI-mediated informal digital learning of Chinese, multicultural personality traits, and willingness to communicate: evidence from plurilingual international students in China

This study examines how plurilingual international students’ generative AI-mediated informal digital learning of Chinese (GenAI-IDLC) interacts with dimensions of multicultural personality to predict their second language willingness to communicate (L2 WTC). Survey responses were...

Saponins induce lipid-dependent structural heterogeneity and modulate membrane organization in phospholipid bilayers

Abstract Saponins are amphiphilic natural compounds whose membrane activity is commonly attributed to sterol complexation, whereas their effects on sterol-free membranes remain poorly understood. Here, we investigated how lipid packing governs the interaction of a Saponaria offic...

Adverse early-life conditions and their impact on the marriage market and social mobility: The Poznań birth cohort, 1830–1855

Objectives Early-life conditions may influence later-life outcomes through biological scarring and selective survival mechanisms. However, the long-term effects of childhood adversity on marriage formation and social mobility remain insufficiently explored in historical populatio...

Mast seeding mitigates the negative demographic effects of conspecific adults on rowan seedling survival.

BACKGROUND AND AIMS: Seedling mortality filters tree recruitment, yet we know little about whether the year in which a seedling is produced leaves a demographic signal after emergence. This gap is central for mast-seeding species, where seed crops vary widely among years and may...

Assessment of Antioxidant Potential and Polyphenol and Mineral Content in Selected Green Vegetables Subjected to Sous Vide Cooking and Steaming

Green vegetables are rich sources of bioactive substances, including polyphenols and minerals, whose content and biological activity change during various technological processes. The aim of this study was to evaluate the effect of sous vide cooking at three different temperature...

Poland's state capitalism, state dirigisme and the European Games

This article examines Poland's organisation of the 2023 European Games as a case study of state capitalism and dirigisme under the Law and Justice (PiS) government. Drawing on qualitative analysis of official documents, public statements and media coverage, the study examines the...

Differential Foraging on Larvae and Puparia of Blow Flies by Carrion‐Associated Predatory Beetles

ABSTRACT Carrion represents a resource‐rich habitat in which strong competitive pressures shape predator coexistence. In such ephemeral systems, predators persist through ecological differentiation, including prey‐stage specialization and contrasting foraging strategies. Although...
