Detailed measurements of finite-amplitude pulses radiated by plane and focused circular pistons in water are presented. Comparisons of time waveforms and frequency spectra, both on and off axis, are made with numerical calculations based on the nonlinear parabolic wave equation. Emphasis is on nonlinear distortion of amplitude- and frequency-modulated tone bursts. Use of short pulses enabled re...

Frontal asymmetry measured at rest using EEG is considered a stable marker of approach-avoidance behaviors and risk taking. We examined whether without salient cues of attention in the form of losses, predictability is reduced. Fifty-seven participants performed an experiential decision task in a gain-only, loss-only, and mixed (gains and losses) condition. Increased risk taking on the part of ...

Past empirical work suggests that aging is associated with decreases in risk taking. But are such effects universal? Life-history theory suggests that the link between age and risk taking is a function of specific reproductive strategies that can be more or less risky depending on the ecology. We assessed variation in the age-risk curve using World Values Survey data from 77 countries (N = 147,...

The present study was an attempt to investigate the validity of the English section of Iranian Universities PhD Entrance Exam in TEFL. To this end, 15 EFL learners from university of Isfahan who were in their last semester of that MA education were invited to contribute to the study. A group of 5 university lecturers were also asked to support the study as expert judges. A TOEFL reading paper w...

Note-taking skills are critical to consecutive interpreting. As an important construct of translation competence and essential skill interpreting performance, note-taking merits rigorous systematic investigations as well reliable valid assessment instruments procedures. In the present study, we aim further validate fluency scale developed by Zhou Dong (2019), focusing on four dimensions, coordi...
