Researchers developed the Original Grit Scale (Grit-O), Short (Grit-S), and Grit-5 to investigate role of grit in explaining educational vocational outcomes. The present study examined structure psychometric characteristics these three measures using data from residents United States (n = 1,915) who completed Grit-O online. We conducted confirmatory factor analyses Kline’s (2016) method assessi...

There are three weighted decompositions of tensors proposed in this paper, and the corresponding definitions generalized tensor functions given. The Cauchy integral formula Moore-Penrose inverse is developed for solving equations. Besides above, we give projection to discuss representations power tensors. Finally, some special studied which can preserve structural invariance under defined paper.

In their original formulation of the method of isotropic extension via structural tensors, which is meant for applications to the derivation of coordinate-free representation formulas for anisotropic constitutive functions, both Boehler and Liu start with the assumption that the invariance group of structural tensors is the symmetry group that defines the anisotropy of the constitutive function...

Abstract This study investigates the measurement invariance of a brief self-report measure childhood social-emotional competencies, Middle Childhood Survey: Social-Emotional Learning (MCS-SEL), across demographic subgroups. Invariance was tested simultaneously among subgroups children aged 11–12 years that were differentiated by sex (male, female) and main language spoken at home (English, not ...

objective: the aim of this study is to explore the confirmatory factor analysis results of the persian adaptation of abbreviated math anxiety scale (amas), proposed by hopko, mahadevan, bare & hunt. method: the validity and reliability assessments of the scale were performed on 298 college students chosen randomly from tabriz university in iran. the confirmatory factor analysis (cfa) was carrie...

this paper is concerned with global analysis of a delay sveir epidemiological model in a population of varying size. by using lyapunov stability method and lasalle’s invariance principle for delay systems, we prove that when there is no endemic equilibrium, the disease free equilibrium is globally asymptotically stable, otherwise the endemic equilibrium is globally stable.

optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 gevic

In the application of content-based image retrieval, the ideal characteristics should be invariance to geometrical transformations. That is, once the image undergoes geometrical transformations, we expect the features extracted from the image are invariant. Thus, in this paper, rotation, scaling and translation (RST) invariant features for image retrieval are investigated, and a new method is p...

Research generally supports a 4-factor structure of posttraumatic stress disorder (PTSD) symptoms. However, few studies have established factor invariance by comparing multiple groups. This study examined PTSD symptom structure using the Davidson Trauma Scale (DTS) across three veteran samples: treatment-seeking Vietnam-era veterans, treatment-seeking post-Vietnam-era veterans, and Operation En...

The association rules algorithms can be used for describing textures if an appropriate texture representation formalism is used. This representation has several good properties like invariance to global lightness and invariance to rotation. Association rules capture structural and statistical information and are very convenient to identify the structures that occur most frequently and have the ...
