The Relationship Between Global Value Chains and Productivity [PDF]

open access: yesInternational Productivity Monitor, 2017
We review the evidence linking Global Value Chains (GVCs) and productivity. GVCs are a key feature of the world economy, with production increasingly fragmented across borders.

A meeting report: cross-cultural comparability of questionnaire measures in large-scale international surveys

open access: yesMeasurement Instruments for the Social Sciences, 2019
The value of cross-country comparisons is at the heart of large-scale international surveys. Yet the validity of such comparisons is often challenged, particularly in the case of latent traits whose estimates are based on self-reported answers to a small

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

The Changing Structure of Global Value Chains: Are Central Hubs Key for Productivity? [PDF]

open access: yesInternational Productivity Monitor, 2018
This article uses “centrality” metrics reflecting position within Global Value Chains (GVCs) to identify central hubs and peripheral European economies and sectors.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Multimodal Cross‐Attentive Graph‐Based Framework for Predicting In Vivo Endocrine Disruptors

open access: yesAdvanced Science, EarlyView.
A multimodal cross‐attentive graph neural network integrates molecular graphs with androgen and estrogen adverse outcome pathway (AOP)–anchored in vitro assay signals to predict in vivo endocrine disruption. By fusing information on Tier‐1 AOP logits with chemical structures, the framework achieves high accuracy and provides assay‐traceable ...

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...
