When Social Media Influencers Work: A Meta‐Analysis of Brand Engagement, Behavioral Intention, and Boundary Conditions

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT This study examines how social media influencers (SMIs) shape brand engagement and behavioral intention and when these effects vary across contexts. Drawing on 97 studies with a sample of 40,330 participants, we employ one‐stage meta‐analytic structural equation modeling (OSMASEM) to estimate the effects of SMI credibility (attractiveness ...

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Paternity annulment

open access: yes, 1998
26 páginasThe emancipating beginning of modernity is properly the paternity annulment and, most deeply, the world's negation as a being created by an authority or by a non order. As the father gives life, he can be considered as the "transcendence symbol"

Peroullazines: Synthesis, Structure, and Optoelectronic Properties

open access: yesChemistry – A European Journal, EarlyView.
Peroullazines, longitudinally π‐extended ullazines featuring a peropyrene‐sized framework, are more electron‐rich than the corresponding peropyrene systems and exhibit optical gaps approaching those of teropyrenes. Regioselective pyridinic nitrogen incorporation further enables frontier‐orbital‐controlled tuning of their optoelectronic properties ...
