There are two styles of learning and thinking: ability based and personality based. The former are assessed by maximum-performance tests, and the latter are assessed by typical-performance tests. We argue that both kinds of styles matter for instruction and assessment in school. In particular, shaping lessons based on an awareness that people learn and think in different ways can lead to improv...

Introduction: The dominant approach in the etiology and treatment of autism spectrum disorder (ASD) is a behavioral approach. Proponents of the behavioral model believe that children with autism in access to capabilities in achieving love, empathy, language and creative thinking, have significant fundamental defects.  Instead model-based development of individual differences relationship offers...

We often wonder how do we behave in a wide variety of ways. Sometimes we feel happy; sometimes sad. The equipment with which we are born – the brain, nervous system and sensory – motor system is central to the functioning of organism. Earlier, it was believed that there is some inner spirit in all of us that controls our behaviour. Today, we know that our actions and bodily movements take place...

We show that oversampled filter banks FBs) offer more design freedom and less noise sensitivity t 6 an critically sampled FBs. We provide a parameterization of all synthesis FBs satisfyin perfect reconstruction for a given oversampled analysis FE, and we derive bounds and expressions for the variance of the reconstruction error due to noisy subband signals. Finally, we introduce noise shaping i...

In an era where development processes seem best characterized by a continuing cycle of macroeconomic crisis and recovery, a critical question for students of the political economy of development concerns identification of the factors that facilitate recovery from economic shock. Recent work on this question has moved beyond a focus on specific macroeconomic policy adjustments toward analysis of...

We describe generation of shaped femtosecond waveforms by using frequency-domain phase-only filters designed by numerical optimization techniques. The task of filter design for pulse shaping in the time domain is directly analogous to the design of phase-only filters for beam shaping and array generation in the spatial domain. We experimentally tested phase filters that were designed to produce...

In this paper, we explore theoretically and experimentally the laser beam shaping ability resulting from the coaxial superposition of two coherent Gaussian beams (GBs). This technique is classified under interferometric laser beam shaping techniques contrasting with the usual ones based on diffraction. The experimental setup does not involve the use of some two-wave interferometer but uses a sp...
