MR2864818 39A05 37B99 Sacker, Robert J. (1-SCA; Los Angeles, CA) An invariance theorem for mappings. (English summary) J. Difference Equ. Appl. 18 (2012), no. 1, 163–166. The following theorem is proved. Theorem 2.1. LetD ⊂ R be a bounded subset and f :D→ R be continuous. Suppose f : ◦ D→ R is injective (one-to-one) and f(∂D)⊂D. If D := R rD has no bounded components, then f(D)⊂D. Here D is the...
Confirmatory factor analytic tests of measurement invariance (MI) based on the chi-square statistic are known to be sensitive to sample size. For this reason, Cheung and Rensvold (2002) recommended using alternative fit indices in MI investigations. However, previous studies have not established the power of fit indices to detect data with a lack of invariance. In this study, we investigated th...
It is a well-documented fact that social trust, i.e., the extent to which people trust others, and political trust, i.e., trust in political institutions, are key factors in social capital theory. However, to compare these concepts in cross-national or longitudinal frameworks, it is important to fi rst establish whether the measurements of these concepts are compatible across countries or over ...
Invariance to various transformations is key to object recognition. Image-plane invariances – such as translation, rotation and scaling – can be computed independently of the specific object. On the other hand, both invariance to rotation in depth and invariance to changes in illumination require implicit information about the 3D structure of the object or its material properties and thus more ...
