DOI: 10.1017/s0140525x21000297

Abstract: Abstract By organizing crowds of scientists to independently tackle the same research questions, we can collectively overcome the generalizability crisis. Strategies to draw inferences from a heterogeneous set of research approaches include aggregation, for instance,… read more here.

DOI: 10.1093/hr/uhac204

Abstract: ABSTRACT Capsaicinoids provide chili peppers (Capsicum spp.) with their characteristic pungency. Several structural and transcription factor genes are known to control capsaicinoid contents in pepper. However, many other genes also regulating capsaicinoid contents remain unknown,… read more here.

recommendations! Published in 2023 at "Axioms"

DOI: 10.3390/axioms12050503

Abstract: Fixed-effect meta-analyses aim to estimate the common mean parameter by the best linear unbiased estimator. Besides unbiasedness, consistency is one of the most fundamental requirements for the common mean estimator to be valid. However, conditions… read more here.
