Relating Measurement Invariance, Cross-Level Invariance, and Multilevel Reliability.
Jak S, Jorgensen TD. Jak S, et al. Front Psychol. 2017 Oct 10;8:1640. doi: 10.3389/fpsyg.2017.01640. eCollection 2017. Front Psychol. 2017. PMID: 29066984 Free PMC article. Review.
This kind of data complicate the evaluation of reliability and measurement invariance, because several properties can be evaluated at both the individual level and the cluster level, as well as across levels. For example, cross-level invariance implies …

Sculpting Computational-Level Models.
Blokpoel M. Blokpoel M. Top Cogn Sci. 2018 Jul;10(3):641-648. doi: 10.1111/tops.12282. Epub 2017 Jun 27. Top Cogn Sci. 2018. PMID: 28653371 Free article.
In this commentary, I advocate for strict relations between Marr's levels of analysis. Under a strict relationship, each level is exactly implemented by the subordinate level. ...Second, similar to how a sculptor chisels away superfluous marble, a modeler can …

Determination of anatomic level of myelomeningocele by prenatal ultrasound.
Barnes KS, Singh S, Barkley A, Lepard J, Hopson B, Cawyer CR, Blount JP, Rocque BG. Barnes KS, et al. Childs Nerv Syst. 2022 May;38(5):985-990. doi: 10.1007/s00381-022-05469-9. Epub 2022 Feb 18. Childs Nerv Syst. 2022. PMID: 35178598
METHODS: The study is a retrospective review including patients born 2011-2019 who had prenatal imaging and primary myelomeningocele closure at a single institution. Lesion levels from prenatal ultrasound and postnatal imaging studies were analyzed for agreement at exact …

Understanding Stress Response in Superorganisms: A Multi-Level and Cybernetic Approach.
Sgolastra F. Sgolastra F. Ecol Evol. 2025 Dec 9;15(12):e72626. doi: 10.1002/ece3.72626. eCollection 2025 Dec. Ecol Evol. 2025. PMID: 41383207 Free PMC article. Review.
This review aims to analyze the current knowledge and propose new approaches to understand how environmental stressors impact insect superorganisms across different levels of biological organization. In all multicellular organisms, stress-response mechanisms are hierarchic …
