What Are the Best Predictors of STEM Competences in PISA 2018? An Analysis of the Spanish Context Using Data Mining

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT The importance of Science, Technology, Engineering, and Mathematics (STEM) subjects for the present and future society is clear. With assessments such as the Programme for International Student Assessment (PISA), the possibility of an analysis on student‐related variables predicting results in STEM areas opens. The aim was to identify the PISA

Escape Body: A Gamified Problem‐Based Learning Project in Primary Education

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT Young learners' lack of motivation to study scientific‐related subjects nowadays is a topic of concern in our society. This study followed a quasi‐experimental design with a predominantly quantitative methods approach, complemented by qualitative data, to investigate how the combination of gamified and problem‐based learning could influence ...

The Fertility Effects of Reducing Implicit Childcare Subsidies: The Case of School Schedules

open access: yesJournal of Policy Analysis and Management, Volume 45, Issue 4, Fall 2026.
ABSTRACT Despite governments’ efforts to raise fertility through family‐support policies, birth rates continue to decline in high‐ and middle‐income countries. Some policies designed for other purposes, however, may function as implicit childcare subsidies.

Barbituric Acids as Nucleophiles in Enantioselective Mannich Reactions: Organocatalytic Access to Quaternary Aminopyrazolone–Barbiturate Adducts

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
An enantioselective Mannich reaction using barbituric acids as nucleophiles provides access to chiral heterocycles bearing quaternary stereocenters. The transformation is catalyzed by a bifunctional thiourea with high selectivity. An immobilized catalyst enables recycling and application under continuous‐flow conditions, offering an efficient and ...

Contact Sensitization in Patients With Frontal Fibrosing Alopecia: Patch Test Results With an Extended Baseline Series in Consecutive Patients

open access: yesContact Dermatitis, Volume 95, Issue 2, Page 192-199, August 2026.
Sensitization to propolis, shellac and gallate mix is FFA‐associated, but its relevance is largely unknown. Sensitization to salicylates is frequent and associated with symptoms of intolerance to sun exposure or sunscreens. No significant improvement by allergen avoidance is identified.

Biogeography of Bursaphelenchus Species Driven by Climate, Vectors and Hosts: Implications for Forest Pathology Under Climate Change

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Wood‐inhabiting nematodes of the genus Bursaphelenchus are a group with significant ecological and economic impacts on global forest ecosystems. This review aims to update current knowledge on their spatial distribution, host‐vector associations and the factors driving species expansion under the framework of climate change.

High‐Dimensional Immune Profiling Identifies Circulating NKT‐Like Cells Associated With Severity Outcome in Acute Pancreatitis at Disease Onset

open access: yesImmunology, Volume 178, Issue 4, Page 685-703, August 2026.
High‐dimensional spectral cytometry of peripheral blood mononuclear cells at hospital admission revealed that acute pancreatitis patients who subsequently developed moderately‐to‐severe disease exhibited a specific reduction of circulating CD2 + CD8dim NKT‐like cells, which appear to acquire an altered cytotoxic‐like phenotype upon IL‐15 stimulation ...

Heterogeneous Organocatalytic Synthesis of Propargylic Esters Using a Polymer‐Supported N‐Heterocyclic Carbene

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
A vinyl addition polynorbornene (VA‐PNB)‐supported N‐Heterocyclic carbene precatalyst is successfully used in the metal‐free coupling of terminal alkynes, carbon dioxide, and chlorides toward propargylic esters. The conversion of carbon dioxide into high‐value chemical scaffolds is a central challenge in modern green chemistry. In this study, we report

Metal‐Free, Mild, and Sustainable Synthesis of Bio‐Based Polyesters via EDC/DMAP‐Mediated Polycondensation: Structure–Property Relationships and Thermal Stability

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
We developed a mild, metal‐free EDC/DMAP‐mediated polycondensation platform for bio‐based polyesters from FDCA (2,5‐furandicarboxylic acid) and succinic acid, enabling access to homopolyesters from unsaturated and aliphatic diols as well as heteropolyesters prepared by one‐pot or sequential routes.

Wine Tourism as a Catalyst for Sustainable Performance: The Mediating Role of Corporate Legitimacy and Green Innovation

open access: yesAgribusiness, Volume 42, Issue 3, Page 1266-1287, Summer 2026.
ABSTRACT This study aims to explore the influence of Wine Tourism (WT) on the Sustainable Performance (SP) of wineries in Spain. It particularly investigates how Corporate Social Legitimacy (CSL) and Green Innovation (GI) may act as intermediary factors in this relationship.
