Predicting principals’ retention in the principalship through professional development, instructional leadership, and job satisfaction: a cross-national meta-analysis of country-specific structural equation models

This research addressed the global challenge of principal retention by examining associations between principals’ professional development activities and their intention to remain, including indirect associations involving instructional leadership and career and workplace satisfa...

Uphill graph topologies and degree-constrained realizations of posets

We define a family of topologies on graphs using degree-constrained reachability. Open sets are closed under paths of nondecreasing or strictly increasing vertex degree; for multigraphs, counting incident edges or distinct neighbours gives further variants. These topologies encod...

Translation as a Double-Edged Sword: Copyright, Dialogue, and Normalization under Colonial Conditions

In early 2018, the publication of Huriya: Sipurim u-reshimot shel yotzrot be-’ikvot ha-Aviv ha-’Aravi (Freedom: Stories and reflections of women authors following the Arab Spring) was announced by Resling, an Israeli publisher. The book seemed especially promising in light of the...

Benchmarking surrogate nulls for neural–choice dependence under drift and selection

Pre-stimulus decoding tests whether neural activity is associated with an upcoming choice, but drift and response-dependent trial inclusion complicate interpretation. We benchmark label-surrogate procedures using simulations and exploratory analyses of public Steinmetz and Intern...

The prime-sandwich property of OEIS A373698

Let a(1) = 1, a(2) = 2, and a(3) = 3. Thereafter choose the least unused positive integer sharing an odd prime factor with the preceding term. I present a computer-assisted proof that every prime p > 3 appears in the consecutive block 3p, p, 2p, a property conjectured in the entr...

Classification autism spectrum disorder associated genes through analysis of the intrinsic disorder in their protein products

Autism Spectrum Disorder (ASD) affects approximately 1–2% of children worldwide, posing challenges for healthcare, education, and families. While genetic factors play a key role, only a small subset of ASD-related genes has been identified with strong genetic evidence. This study...

The Maintenance of the Longitudinal Subtropical Jet Structure During Austral Winter

Abstract The austral winter subtropical jet maintenance is analyzed by comparing the observed upper tropospheric zonal momentum budget with an idealized aquaplanet model simulation with localized tropical heating in the summer hemisphere. The model and observations show great sim...

Toward a synchronization theory of school readiness for change: The impact of managerial innovation synchronicity, team communication synchronicity, and team emotional synchronicity on teachers’ readiness for change in schools

Abstract Synchronicity remains an underexplored perspective in the study of educational change. Traditional models often neglect the intricate interaction between management, communication, and emotional alignment, identified here as factors essential for implementing effective c...

How Norms Depend on the Presence and Status of Observers: The Relational Contingency of Everyday Behaviors in 90 Societies

Norms are fundamental to social life, but basic questions about how they are affected by social context remain. Specifically, how do normative constraints depend on the presence and status of observers, and how do such relational contingencies vary across cultures? Using data fro...

Females cooperate, rather than monopolize reproduction, in multi-female groups of cooperatively breeding birds and mammals

Abstract Scholars have long sought to understand why, in some cooperatively breeding species, females care for the offspring of other group members while forgoing their own reproduction. Here, we analysed data from 101 cooperatively breeding populations of 73 bird and mammal spec...

Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

A values-illustration definition of art, scored against a verbatim-grounded corpus

This is a short record, not a full paper. It states a definition of art, gives its provenance, and reports how well it fits a corpus of cases taken verbatim from the literature. The definition. “An object, action or product created or chosen deliberately to illustrate values.” Tw...
