The Surprising Bias of PPML Estimates of Structural Gravity Models With Two‐Way Fixed Effects

Review of International Economics, EarlyView.
ABSTRACT The previous literature has shown that the Poisson Pseudo‐Maximum Likelihood (PPML) estimator provides consistent and asymptotically unbiased estimates of the parameters of structural gravity models with two‐way fixed effects, although their standard errors need correction.

Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

Sedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

Serial‐Mediation Study of STEM Outreach Workshops, Cognitive Variables, Identity and Grade‐12 Students' Career Aspirations

School Science and Mathematics, EarlyView.
ABSTRACT This study examined the direct and indirect effects of science, technology, engineering, and mathematics (STEM) outreach workshops on Grade 12 students' STEM career‐choice goals. Using a hybrid conceptual framework that combines social cognitive career theory and science identity theory and employing serial mediation analysis, the study ...

Motives and barriers to blood donation among adults aged over 50 years: A qualitative analysis

Transfusion Medicine, EarlyView.
Abstract Background Ageing populations will increase demand for blood‐products and donors who supply them. While blood collection agencies (BCAs) typically target younger people to expand supply, recruiting donors aged 50+ is also a potential solution. However, few studies focus exclusively on this group.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,
