Evaluating the Quality of Corruption Surveys for Comparative Research and Sustainable Development

open access: yesSustainable Development, EarlyView.
ABSTRACT Reliable and accurate corruption measurement is crucial for effective governance, evidence‐based policymaking, and the monitoring of global goals such as the United Nations Sustainable Development Goals (SDGs). While perception‐based corruption metrics are widely used, they face criticism due to conceptual ambiguities and vulnerability to ...

Unraveling Size Dependent Bi‐ and Tri‐Exciton Characteristics in CdSe/CdS Core/Shell Quantum Dots via Ensemble Time Gated Heralded Spectroscopy

open access: yesSmall, EarlyView.
The size‐dependent biexciton binding energy in CdSe/CdS quantum dots is measured via ensemble time‐gated heralded spectroscopy, showcasing a transition between repulsive and attractive exciton‐exciton interactions. The spectrum and dynamics of two triexciton transitions are resolved and isolated from emission of multiexcitons of higher order.

Physical structural assessment of a segmented concrete shell building floor prototype

open access: yesStructural Concrete, EarlyView.
Abstract To reduce the significant environmental impact of the construction industry, building floors designed as concrete shells that work mainly in compression and that are segmented for prefabrication and disassembly offer a promising alternative to reinforced thick flat slabs.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We
