Cross-Cultural Differences and Psychometric Properties of the Japanese Actions and Feelings Questionnaire (J-AFQ)
Aims: We aimed to assess the psychometric properties of a Japanese version of the Actions and Feelings Questionnaire (J-AFQ), an 18-item self-report measure of non-verbal emotional communication, as well as to examine its transcultural properties.Methods: The J-AFQ was administered to 500 Japanese adults (age 20–49, 250 male), alongside the Japanese Broad Autism Phenotype Questionnaire (BAPQ-J) and Empathy Quotient (EQ-J). These were compared to a group of 597 British and Irish participants (age 16–18, 148 male). J-AFQ was assessed in terms of validity by confirmatory factor analysis and convergence with BAPQ-J and EQ-J using Pearson correlation. Internal consistency and differential item functioning (DIF) were assessed and compared between Japanese and UK/Irish participants.Results: Reversed worded items (RWIs) showed poor item-total correlations but excluding these left a 13-item version of the J-AFQ with good internal consistency and content validity. Consistent with the English version, J-AFQ scores correlated with EQ and lower BAPQ scores. However, comparing across cultures, J-AFQ scores were significantly lower in the Japanese sample, and there was evidence of important DIF by country in over half of the J-AFQ itemsConclusion: Cultural differences in attitudes to self-report, as well as increased acquiescence to RWI's also seen in previous studies, limit the value of the 18-item instrument in Japanese culture. However, the 13-item J-AFQ is a valid and reliable measure of motor empathy, which, alongside the English version, offers promise for research in motor cognition and non-verbal emotional communication across cultures
Renormalization Group Running of Newton's G: The Static Isotropic Case
Corrections are computed to the classical static isotropic solution of
general relativity, arising from non-perturbative quantum gravity effects. A
slow rise of the effective gravitational coupling with distance is shown to
involve a genuinely non-perturbative scale, closely connected with the
gravitational vacuum condensate, and thereby, it is argued, related to the
observed effective cosmological constant. Several analogies between the
proposed vacuum condensate picture of quantum gravitation, and non-perturbative
aspects of vacuum condensation in strongly coupled non-abelian gauge theories
are developed. In contrast to phenomenological approaches, the underlying
functional integral formulation of the theory severely constrains possible
scenarios for the renormalization group evolution of couplings. The expected
running of Newton's constant is compared to known vacuum polarization
induced effects in QED and QCD. The general analysis is then extended to a set
of covariant non-local effective field equations, intended to incorporate the
full scale dependence of , and examined in the case of the static isotropic
metric. The existence of vacuum solutions to the effective field equations in
general severely restricts the possible values of the scaling exponent .Comment: 61 pages, 3 figure
Predicting the critical density of topological defects in O(N) scalar field theories
O(N) symmetric field theories describe many critical
phenomena in the laboratory and in the early Universe. Given N and ,
the dimension of space, these models exhibit topological defect classical
solutions that in some cases fully determine their critical behavior. For N=2,
D=3 it has been observed that the defect density is seemingly a universal
quantity at T_c. We prove this conjecture and show how to predict its value
based on the universal critical exponents of the field theory. Analogously, for
general N and D we predict the universal critical densities of domain walls and
monopoles, for which no detailed thermodynamic study exists. This procedure can
also be inverted, producing an algorithm for generating typical defect networks
at criticality, in contrast to the canonical procedure, which applies only in
the unphysical limit of infinite temperature.Comment: 4 pages, 3 figures, uses RevTex, typos in Eq.(11) and (14) correcte
