This paper summaries our recent work on the application of the concepts of capacity per unit cost and reliability function per unit cost to models of fading channels. The cost is taken to be the energy, or a certain fourth moment functional that is sensitive to the bursti-ness of the signals, and is related to the ambiguity function of the input signal. The channel is assumed to be a Wide-Sense...

Five hundred and forty five Chinese students participated in study aimed to examine multi-dimensionality of creativity self-efficacy and its contextual (i.e., classroom environment) correlates. Nearly all aspects in the What Happens in the Classroom Scale (e.g., student cohesiveness, investigation, and task orientation) were found to have significant, positive correlations with all subscales of...

Some theories implicate abnormal self-schemas in the development of psychosis in general and in paranoid delusions in particular. Patients with delusions may also be highly intolerant of ambiguity. No study has yet compared remitted and currently ill paranoid patients on schema measures, or on tolerance of ambiguity. Currently ill psychotic patients with persecutory delusions, patients whose pe...

Inferior temporal (IT) cortex as the final stage of the ventral visual pathway is involved in visual object recognition. In our everyday life we need to recognize visual objects that are degraded by noise. Psychophysical studies have shown that the accuracy and speed of the object recognition decreases as the amount of visual noise increases. However, the neural representation of ambiguous visu...

Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism-intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification). A meta-analysis (88 samples, 12 countries, 22,818 cases) confirms that several psycho...
