Professor Patten's Theory of Prosperity

Psychometric Properties of the Brief Form of Professor-Students Rapport Scale-based on Classical Test Theory and Item-Response Theory

Introduction: In order to improve the quality of the teaching process, it is necessary to review the professor-student rapport. The purpose of the present study was to investigate the factor structure and item-response parameters of Professor-Students Rapport Scale-Brief (PSRS-B). Methods: In a descriptive-correlation study, 497 students from Shahid Beheshti University of Medical Sciences were ...

Dynamics of Inclusive Prosperity

Patience and prosperity

This paper introduces wealth-dependent time preference into a simple model of endogenous growth. The model generates adjustment dynamics in line with the historical facts on savings and economic growth in Europe from the High Middle Ages to today. Along a virtuous cycle of development more wealth leads to more patience, which leads to more savings and even higher wealth. Savings rates and incom...

THEORY OF THE TRAVELLING-WAVE PARAMETRIC AMPLIFIER By Professor

The theory of a parametric travelling-wave amplifier is developed, including the pumping wave explicitly. Particular reference is made to two characteristics of such amplifiers which theories assuming a constant pumping-wave amplitude fail to predict. The first arises from ohmic attenuation in the line, and limits the useful length of line to a length of the order of (ot\a.i)~l, where <xi and 0...

Some Functional Equations in the Theory of Relativity. by Professor

IN transcribing the process of light-signalling which leads to his kinematic equations of transformation, Einstein* obtains relations, connecting the space-time coordinates in two systems of reference, in the form of functional equations. He solves these by passing to partial differential equations, and restricts the solutions to linearity by a rather obscure appeal to the homogeneity of time a...
