This report describes the development of grade norms for timed-writing performance in two modes of writing: persuasive and descriptive. These norms are based on objective and automatically computed measures of writing quality in grammar, usage, mechanics, style, vocabulary, organization, and development. These measures are also used in the automated essay scoring system e-rater V.2. Norms were ...

a r t i c l e i n f o We investigate how team and individual performances of players in the National Basketball Association respond to variations in intra-team pay inequality. By breaking down team dispersion into conditional and expected components, we find that expected pay dispersion has a positive effect on team and individual performance. We find that team and individual performances are e...

Emotional expressivity in singing is examined by comparing neutral and expressive performances of a set of music excerpts as performed by a professional baritone singer. Both the neutral and the expressive versions showed considerable deviations from the nominal description represented by the score. Much of these differences can be accounted for in terms of the application of two basic principl...

PURPOSE The purpose of the present study was to compare different software algorithms for processing DSC perfusion images of cerebral tumors with respect to i) the relative CBV (rCBV) calculated, ii) the cutoff value for discriminating low- and high-grade gliomas, and iii) the diagnostic performance for differentiating these tumors. METHODS Following approval of institutional review board, in...

We examined goal importance, focusing on high, but not exclusive priority goals, in the theory of planned behaviour (TPB) to predict students’ academic performance. At the beginning of semester, students in a psychology subject (N = 197) completed TPB and goal importance items for achieving a high grade. Regression analyses revealed partial support for the TPB. Perceived behavioural control, bu...

Previous studies associated feedback to positive improvements in both the performance and behavior of students. This study evaluated effects on task grade 4 students context learning multiplication mathematics subject. Through an experimental research, given was form by hand technique. There were 40 randomly selected participants distributed equally control groups. research-made test question, ...

OBJECT Preoperative knowledge of meningioma grade is essential for planning treatment and surgery. The purpose of this study was to investigate the diagnostic value of MRI texture and shape analysis in grading meningiomas. METHODS A surgical database was reviewed to identify meningioma patients who had undergone tumor resection between January 2015 and December 2016. Preoperative MR images we...

This paper describes the development of a Grade Transition optimizer PathFinder that enables a high performance demand driven operation in the chemical process industry. The technology makes use of a dynamical rigorous model based optimization of an economic criterion along a grade change trajectory. An application on a large grade slate for a polyethylene gasphase reactor is discussed. Copyri...

Weaver and Bryant (1995) proposed the optimum effort hypothesis, suggesting that undergraduate students were better able to predict comprehension when text materials matched their reading level (grade 12) as opposed to being too easy or too difficult (Weaver and Bryant did not assess the actual reading level of their participants). In the study, we examined the reading level and accuracy of per...
