This study investigated the answer changing behavior of the Iranian university students and its relationship to the academic course, gender, and field of study. 362 students at the University of Isfahan took part in the study. 76 English language teachers were also surveyed for their attitude toward answer changing on MC tests. The results indicated that 42.11% of the teachers had a negative at...

In order that discrete symmetries should not be violated by gravitational effects, it is necessary to gauge them. In this paper we discuss the gauging of ZZN from the breaking of a high energy SU(N) gauge symmetry, and derive consistency conditions for the resulting discrete symmetry from the requirement of anomaly cancellation in the parent symmetry. These results are then applied to a detaile...

in both developing and developed countries, health ministries closely examine use of so-called nudges to promote population health and welfare. cass sunstein and richard thaler, who developed the concept, define a nudge as “any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives. ...

This paper proposes a general convex framework for the identification of switched linear systems. The proposed framework uses over-parameterization to avoid solving the otherwise combinatorially forbidding identification problem and takes the form of a least-squares problem with a sum-of-norms regularization, a generalization of the `1-regularization. The regularization constant regulates compl...
