On Quadratic Periodic Points of Quadratic Polynomials
We focus on a very specific case of the Uniform Boundedness Conjecture, namely, bounding the number of possible c such that the quadratic polynomial φc(z) = z2 + c has quadratic periodic points of some small period. We show that there are infinitely many rational c with quadratic 4-cycles, with all such c completely understood; and only finitely many rational c with quadratic 5-cycles (we conje...
متن کاملPeriodic Points of Quadratic Polynomials
A point of period k of a function f is a point x such that f (x) = x but f (x) 6= x for any 0 < i < k. Let φk(f) denote the number of real points of period k of f . In the case that f is a quadratic polynomial, we develop an algorithm to explicitly characterize φk(f) in terms of the coefficients of f. We show the resulting characterization for k ≤ 6. The method extends to higher k and higher de...
متن کاملTragedy on grade crossing: driver failure or systemic fragility?
In 2010, an accident occurred in Americana-SP, Brazil, involving two trains and one bus on a Grade Crossing, when 10 people died and 17 were injured including workers. This paper aims to analyze the accident using the Model of Analysis and Prevention of Work Accidents (MAPA). The method provides observation of work, interviews and analysis of documents to understand precedents of the event in t...

متن کاملQuantifying Statistical Control: Crossing the Threshold of Theoretical Randomization
In this paper we will argue that quasi-experiments can be equated to theoretical randomized experiments based on the extent of statistical control for confounding factors accounted for by measures such as a pre-test. That is, we use theoretical randomization as a baseline for evaluating the effective control of any study instead of using a single randomized empirical study as a gold standard ag...
