BACKGROUND A high percentage of young children present with flatfeet. Although the percentage of those with flatfeet declines with age, about 15% of the population maintains a flat arch. A reduction in longitudinal arch height usually combines with excessive subtalar joint pronation and may be related to other musculoskeletal problems of the lower extremity kinetic chain. The purpose of this st...

The financial economics literature proposes dozens of performance measures to be used, for instance, to compare, analyse, rank and select assets. There is thus a problem: which measures should be considered? We extend the current literature by comparing a large set of performance measures over more than one thousand of equities included in the Standard & Poor’s 1500 index. We evaluate performan...

developmental dysplasia of the hip (ddh) and flatfoot are common pediatric orthopedic disorders, being referred to and managed by both general and pediatric orthopedic surgeons, through various modalities. our study aimed to evaluate their consensus and perspective disagreements in terms of diagnostic and therapeutic approaches of the mentioned deformities. forty participants in two groups of g...

We introduce the Realized Exponential GARCH model that can utilize multiple realized volatility measures for the modeling of a return series. The model specifies the dynamic properties of both returns and realized measures, and is characterized by a flexible modeling of the dependence between returns and volatility. We apply the model to DJIA stocks and an exchange traded fund that tracks the S...

background and purpose: delirium is a clinical syndrome with cognitive disorder, which occurs within a short time in the admitted patients, specially the elderly. regarding the fact that one third of the delirium incidences is preventable, applying nursing preventive measures is an issue of fundamental importance. the present study aimed to perform a systematic review over the nursing preventiv...

This article describes a method for selecting design parameters and a particular sequence of events in fMRI so as to maximize statistical power and psychological validity. Our approach uses a genetic algorithm (GA), a class of flexible search algorithms that optimize designs with respect to single or multiple measures of fitness. Two strengths of the GA framework are that (1) it operates with a...

OBJECTIVE Although repeated-measures designs are increasingly common in research on psychosomatic medicine, they are not well suited to the conventional statistical techniques that scientists often apply to them. The goal of this article is to introduce readers to mixed regression models, which provide a more flexible and accurate framework for managing repeated-measures data. METHODS AND RES...

The traditional focus of scheduling research is on finding schedules with a low implementation cost. However, in many real world scheduling applications finding a robust or flexible schedule is just as important. A robust schedule is a quality schedule expected to still be acceptable if something unforeseen happens, while a flexible schedule is a quality schedule expected to be easy to change. ...
