Biodiversity science is improved when silent herbaria speak

PLANTS, PEOPLE, PLANET, EarlyView.
Herbaria in the Global South are critical yet underutilized resources for biodiversity science and often absent from international databases and research networks. We highlight the phenomenon of “silent herbaria” using Nigeria as a case study and quantify how these collections fill important gaps in global biodiversity knowledge.

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

Gender Differences in Risk Preferences: Implications for Adoption of Climate Smart Agricultural Technologies

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The gender gap in risk preferences in rural farm households, with female farmers commonly viewed as more risk‐averse than their male counterparts, may have profound implications for addressing the gendered impacts of climate change. Understanding these gender differences and their drivers is essential for designing policies that enhance ...

It draws on ìtàn, a distinct oral source, to show that conjugality shaped Yoruba processes of urbanisation and political centralisation, gendered divisions of labour and social innovation and creativity.

Estimating Causal Effects With Observational Data: Guidelines for Agricultural and Applied Economists

Journal of Agricultural Economics, EarlyView.
ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Enhanced inverse Faraday effect and time-dependent thermo-transmission in gold nanodisks

Nanophotonics
Nonmagnetic media can be magnetized by light via processes referred to as an inverse Faraday effect (IFE). With nonmagnetic metal nanostructures, the IFE is dominated by the presence of light-induced solenoidal surface currents or plasmons with orbital ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Green approach to phytomediated synthesis of silver nanoparticles utilizing Ixora flower extract and their antioxidant potential

Hybrid Advances
This study aims to investigate the antioxidant characteristics of silver nanoparticles (AgNPs) synthesized using Ixora flower extract (IFE). The IFE-AgNPs were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Ultraviolet ...

‘Like the Angel of Death Appearing to Take the Children Away’: The Portrayal of the Norwegian Child Welfare Service Among First‐Generation Muslim Parents

Child &Family Social Work, EarlyView.
ABSTRACT This study explores the perceptions of Norway's Child Welfare Services (CWS), or barnevernet, among first‐generation Muslim migrant parents. It focuses on how personal experiences and community narratives shape attitudes. Using data from semi‐structured interviews with 24 first‐generation Muslim migrant parents, the findings reveal a stark ...
