This paper characterizes ambiguity averse preferences in the absence of the completeness axiom. We axiomatize multiple selves versions of some of the most important ex...

We show that an increase in uncertainty about the probability of being audited (ambiguity) increases tax compliance for ambiguity-averse taxpayers but reduces compliance for ambiguity lovers. Because experimental evidence reveals considerable heterogeneity with respect to ambiguity preferences, we conclude that fostering uncertainty about the probability of being audited may not be an effective...

ambiguity is one of very important techniques in persian rhetoric, but in spite of its importance, it seems there is not enough accuracy in its definition and types.  the present essay tries to redefine the concept of ambiguity. we will begin by analyzing the definitions of ambiguity and amphiboly according to the old and new persian sources; then we presents a new definition and review and ana...

A coherent train of identical Linear-FM pulses is a popular radar signal, mainly due to its good range and Doppler resolution. One of its drawbacks is the relatively high autocorrelation function (ACF) sidelobes. We show how to completely remove most of the sidelobes by diversifying the pulses through overlaying them with orthogonal coding. The technique applies to any other type of pulses – an...

This study investigated teachers’ conceptions of intelligence (TCoI) and ambiguity tolerance in the burnout levels of 202 Iranian EFL teachers. To this end, 3 inventories were utilized: Language Teachers’ Conceptions of Intelligence Scale (LTCI-S), Multiple Stimulus Types Ambiguity Tolerance Scale-II (MSTAT-II), and Maslach Burnout Inventory (MBI). Pearson multiple correlation coefficients and ...

| We present results concerning three diierent types of quartic (fourth order) time-frequency distributions. First, we present new results on the recently introduced local ambiguity function, and show that it provides more reliable estimates of instantaneous chirp rate than the Wigner distribution. Second, we introduce the class of quartic, shift-covariant, time-frequency distributions, and inv...

The paper investigates the properties of ambiguity functions of 2-D analytic, quaternionic and monogenic signals. In the introduction the notions of the above signals and their Wigner distributions and ambiguity functions are recalled. The properties of the ambiguity functions are investigated using two kinds of test signals: A band-pass test signal in the form of a sum of two harmonic signals ...
