In this research work, the results obtained from the SCORM Cloud module verification in a learning platform (Learning Management System) Moodle 1.9.19, are presented. For this module verification, learning objects based on standard SCORM 2004 Fourth Edition were used, with sequencing according to ADL proposed template 10 and whose sequencing process was developed in a previous, published, resea...

This study describes the process of constructing proxy variables from recorded log data within a Learning Management System (LMS), which represents adult learners’ time management strategies in an online course. Based on previous research, three variables of total login time, login frequency, and regularity of login interval were selected as candidates from the data set, along with a guideline ...

This paper deals with the improved forecasts for the values of the study variable in linear regression models utilizing the minimum risk approach. It considers the simultaneous forecasting of actual and average values of the study variable and reports the performance properties of the classical unbiased forecasts and two biased forecasts with respect to the criteria of the bias vector,mean squa...

“Yesterday the S&P500 went up by 3%”. Is this number telling all the story if half the stocks went up 5% and half went down 1%? Surely one can do a little better and give two figures, the average and the dispersion around this average, that two of us have recently christened the variety [1]. Call ri(t) the return of asset i on day t. The variety V(t) is simply the root mean square of the stock ...

Abstract. Understanding and quantifying land management impacts on local climate is important for distinguishing between the effects of large-scale forcings. This study first time explicitly considers radiative forcing resulting from realistic offers new insights into surface response to management. Regression-based trend analysis applied observations present-day ensemble simulations with Commu...
