The static form of the size-distance invariance hypothesis asserts that a given proximal stimulus size (visual angle) determines a unique and constant ratio of perceived object size to perceived object distance. A proposed kinetic invariance hypothesis asserts that a changing proximal stimulus size (an expanding or contracting solid visual angle) produces a constant perceived size and a changin...

For any such use of scale scores, there is a critical assumption that the scale is measuring the same trait in all of the groups. If that assumption holds, then comparisons and analyses of those scores are acceptable and yield meaningful interpretations. But if that assumption is not true, then such comparisons and analyses do not yield meaningful results. This is the general issue of (MI). mea...

in this paper, we prove the strong uniform consistency and asymptotic normality of the kernel density estimator proposed by jones [12] for length-biased data.the approach is based on the invariance principle for the empirical processes proved by horváth [10]. all simulations are drawn for different cases to demonstrate both, consistency and asymptotic normality and the method is illustrated by ...

We give a gauge invariant formulation of N = 2 supersymmetric abelian Toda field equations in N = 2 superspace. Superconformal invariance is studied. The conserved currents are shown to be associated with Drinfeld-Sokolov type gauges. The extension to non-abelian N = 2 Toda equations is discussed. Very similar methods are then applied to a matrix formulation in N = 2 superspace of one of the N ...

The Technological, Pedagogical, and Content Knowledge (TPACK) framework – a framework which proposes a set of knowledge domains that are essential for effective teaching with technology – has gained considerable attention in the domain of education and technology. With the efforts to conceptualize these knowledge domains comes the question to what extent they can be distinguished empirically. H...

When faced with adverse situations in exchange relationships, the people involved are required to respond. Response strategies are reactions to such adverse situations and represent cognitive schemata organized in an integrated structure forming a mental map. Extant response strategy research implicitly assumes that the content and internal structure of response strategies is universal, but wit...

The purpose of this study was to test measurement invariance of the WISC-IV factorial structure between genders. Both 10 and 15 subtest sets were tested on a nationally-representative sample of 2200 children (males N = 1100; females N = 1100). Results from multisample analyses supported partial measurement invariance. Except for a few subtle discrepancies involving correlated error terms, the h...
