The aim of the present study was to adapt the Preference for and Tolerance of the Intensity of ExerciseQuestionnaire (PRETIE-Q) for the Brazilian population and to perform an initial psychometric evaluation. The study consisted of two phases: I) translation and back-translation and production of a Brazilian Portuguese version of the questionnaire; and II) psychometric evaluation and construct v...

Growth charts of body mass index (BMI) are constructed from the recent four-year national crosssectional survey data (1999−2002) using parametric quantile regression methods, which are implemented with a newly developed SAS procedure (http://www.sas.com/statistics) and SAS macros.

Conventional human-computer interfaces for the exploration of volume datasets employ the mouse as an input device. Specifying an oblique orientation for a crosssectional plane through the dataset using such interfaces requires an indirect approach involving a combination of actions that must be learned by the user. In this paper we propose a new interface model that aims to provide an intuitive...

Abstract We develop a novel methodology for the proxy variable identification of firm productivity in presence productivity-modifying learning and spillovers which facilitates unified "internally consistent" analysis spillover effects between firms. Contrary to popular two-step empirical approach, ours does not postulate contradictory assumptions about firmproductivity across estimation steps. ...

Background: Educational Development Center (EDC) establishment is one of the procedures to improve quality of medical education. As positive knowledge and attitude of lecturers and students are essential factors to gain access to goals of these centers, the aim of this project was to assess knowledge and satisfaction of faculty members and students about EDC activities, Babol-2010.

Background: Coasting is one of the most common strategies which has been proposed for preventing ovarian hyperstimulation (OHSS) in overstimulated cycles. However, the debate on the effect of coasting duration (days) on ART cycles outcome is ongoing. This study aimed to assess the influence of coasting duration in oocytes number and quality and fertilization rate in patients with male factor in...

Using market prices for crude-oil futures options and the prices of their underlying futures contracts, we estimate the volatility skew in two ways. As a benchmark for our theoretical model, on each date we first estimate a crosssectional polynomial structure for each maturity to demonstrate the strength and weaknesses of a purely-mechanical model. We then apply to the empirical data a Merton-s...
