Invariants and Mathematical Structuralism
Philosophia Mathematica, 2013The paper outlines a novel version of mathematical structuralism related to invariants. The main objective here is twofold: first, to present a formal theory of structures based on the structuralist methodology underlying work with invariants. Second, to show that the resulting framework allows one to model several typical operations in modern ...

Invariants of Conformai and Projective Structures
Results in Mathematics, 1995Given a non-degenerate affine hypersurface \(M^n\) of \(\mathbb{R}^{n+ 1}\), then any so-called relative normalization (that is, the choice of a transversal vector field with vanishing transversal connection form) induces a semi-Riemannian metric \(h\) and a torsion-free Ricci-symmetric connection \(\nabla\) on \(M^n\).

Factor structure, measurement invariance and structural invariance of the MSCEIT V2.0
Personality and Individual Differences, 2011This study explored factor structure and measurement and structural invariance of the MSCEIT V2.0 across two age groups: 258 young (18–31 years) and 262 older adults (32–79 years). Results supported a three-factor solution reflecting the Experiential Emotional Intelligence area, and Understanding Emotions and Managing Emotions branches.

Coverage and invariability by structural functions
International Journal of General Systems, 2006Based on some of the results and definitions provided in the article System linkage: Structural functions and hierarchies (Lloret et al. “System linkage: structural functions and hierarchies”, Cybern. Syst. Int. J., 29, pp. 35–46, 1998) and adding new definitions that are in keeping with the spirit of the same article, new results have been obtained ...

Invariance in the MMPI's Component Structure
Journal of Personality Assessment, 1987Bernstein and Garbin (1985b) suggested that the Minnesota Multiphasic Personality Inventory's major clinical scales (excluding Scales ? and 5) can be approximated by an oblique three-component structure: (a) Profile Elevation, (b) Test-taking Attitudes, and (c) Optimism-Pessimism, collectively termed the salient weight model.

Hybrid Invariance and Oligarchic Structures
The B.E. Journal of Theoretical Economics, 2017AbstractThis study addresses the problem of Arrovian preference aggregation. Social rationality plays a crucial role in the standard Arrovian framework. However, no assumptions on social rationality are imposed here. Social preferences are allowed to be any binary relation (possibly incomplete and intransitive).

Structural invariants in protein folding
Nature, 1975An analysis of 15 protein structures indicates: First, the loss of accessible surface area by monomeric proteins on folding-proportional to hydrophobic energy-is a simple function of molecular weight; second, the proportion of polar groups forming intramolecular hydrogen bonds is constant; and third, protein interiors are closely packed, each residue ...

On Multiplicative Galois Structure Invariants
American Journal of Mathematics, 1995It is shown that work of Fröhlich on an integral version of the Stark-Tate regulator represents approximations to a conjecture of Chinburg on a multiplicative Galois structure invariant. Taken in conjunction with recent work of Snaith on the additive Chinburg invariants, it follows that all the conjectures of Chinburg hold in two special types of ...

Invariant Functions on Measurement Structures
Journal of Mathematical Psychology, 1995Since the publication of \textit{S. Stevens}' celebrated articles [Science 103, 677-680 (1946); S. Stevens (ed.), Handb. Exp. Psychol., 1-49 (1951)]\ the relationship between measurement structures and appropriate statistics has been an outstanding problem. In an attempt to explicate Stevens' idea of ``permissible statistics'', \textit{E. W.
