Model‐based variance partitioning for statistical ecology

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Variance partitioning is a common tool for statistical analysis and interpretation in both observational and experimental studies in ecology. Its popularity has led to a proliferation of methods with sometimes confusing or contradicting interpretations.

Being a physicist: Gendered identity negotiations on the pathways to becoming an elite female physicist in the United Kingdom

Journal of Research in Science Teaching, Volume 62, Issue 2, Page 426-460, February 2025.
Abstract Much research investigates why women do not participate in physics, or why female attrition in physics is high; this study focuses on elite female academic physicists and how they have persisted and succeeded in their fields. As opposed to researching reasons for attrition or not participating, this study focuses on six elite female academic ...

IAPSO Standard Seawater: definition of the uncertainty in the calibration procedure, and stability of recent batches [PDF]

, 2007
Standard seawater (SSW) has been employed by oceanographers as a reference material in the determinationof salinity for over a century. In all that time, this is the first study to determine the uncertaintyof the SSW manufacturing process.

“On Mars, we will speak Arabic”: Negotiating identity in upper secondary physics in Denmark

Science Education, Volume 108, Issue 6, Page 1698-1724, November 2024.
Abstract Seeking to make upper secondary school physics more relevant and engaging, an online collaborative learning curriculum was designed. Each of the curriculum's lessons was structured as a goal‐based scenario about human scientists on Mars. Video and audio data from the curriculum's implementation in Denmark was collected. This study utilized the

On the Solution of the Hamilton-Jacobi Equation by the Method of Separation of Variables [PDF]

, 2000
The method of separation of variables facilitates the integration of the Hamilton-Jacobi equation by reducing its solution to a series of quadratures in the separable coordinates.

Adjoint Symmetries, Separability, and Volume Forms [PDF]

, 2020
.Two results of a preceding paper are generalized. The rst is about characterizing to what extent preservation of the energy function of a Lagrangian of mechanical type turns dynamical symmetries into Noether symmetries.

Schrödinger symmetry in cosmology and black hole mechanics

, 2022
International audienceWe show that the (symmetry-reduced) gravitational sectors describing i) the flat FRLW cosmology filled with a massless scalar field and ii) the Schwarzschild black hole mechanics both admit the two dimensional centrally extended ...

Orthogonal Separation of The Hamilton-Jacobi Equation on Spaces of Constant Curvature [PDF]

, 2014
What is in common between the Kepler problem, a Hydrogen atom and a rotating black- hole? These systems are described by different physical theories, but much information about them can be obtained by separating an appropriate Hamilton-Jacobi equation ...

Significant difference in femoral torsion between coronal plane alignment of the knee type 1 and 4

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 32, Issue 5, Page 1199-1206, May 2024.
Abstract Purpose The purpose of this study was to find out whether the torsions of the femur and tibia are dependent on the coronal plane alignment of the knee (CPAK) type. Methods Five hundred patients (1000 legs) were included, who received a whole leg standing three‐dimensional (3D) radiograph using EOS imaging (EOS Imaging, Paris, France).

Beyond statistical significance: Five principles for the new era of data analysis and reporting

Journal of Consumer Psychology, Volume 34, Issue 1, Page 177-186, January 2024.
Abstract A crisis of confidence in research findings in consumer psychology and other academic disciplines has led to various proposals to abandon, replace, strengthen, or supplement the null hypothesis significance testing paradigm. The proliferation of such proposals, and their often‐conflicting recommendations, can increase confusion among ...
