Global sensitivity analysis can be used to identify and rank variables importance (sensitivities) for design objectives and constraints, where the solution space is sampled and a linear regression model is normally adopted in the stepwise manner. The relative importance of variables can be examined by three indicators: the order of variables entry into the linear regression model; the absolute ...

The main goal of this study is to estimate the extent to which perceived innovation characteristics are associated with the probability of task related ICT use among secondary school teachers. The tasks were categorized as teaching preparation, teaching delivery, and management. Four hundred and sixteen teachers from secondary schools in Turkey, completed a questionnaire, which was designed to ...

This study examines the acoustic characteristics which native speakers use as cues when judging speech samples. 17 words produced by 98 (15 native speakers and 83 Japanese learners of English) were collected and evaluated. Following this, the first three formants for each vowel produced were measured and used as independent variables in stepwise multiple regression analyses to explain variance ...

The low-temperature electrical resistivity of corrugated semiconductor films is theoretically considered. Nanoscale corrugation enhances the electron-electron scattering contribution to the resistivity, resulting in a stepwise resistivity development with increasing corrugation amplitude. The enhanced electron scattering is attributed to the curvature-induced potential energy that affects the m...

This article purports to investigate the relationship – in an empirical way – between the various operational indicators currently used for the management of call centers in Brazil and customer satisfaction. In this context, a set of call centers rendering services to a telecommunications company will be analyzed in order to verify which of their indicators are positively associated with custom...

Four studies out of a series of 6 previous studies have found that predictive models are more accurate at predicting actual match outcomes when the modelling assumptions are violated than when data are transformed to satisfy the assumptions. The current investigation produced two sets of two predictive models of the 2011 Rugby World Cup; one set of models used raw independent variables that vio...

This study analyzed gender differences in self-regulated learning components, motivational beliefs and achievement in self-regulated online learning environment. Sample of the study consisted of 145 participants from an online programming course which is based on synchronous and asynchronous communication methods over the Internet. Motivated Strategies for Learning Questionnaire (MSLQ) was used...
