Coefficient alpha and related internal consistency reliability coefficients.
The author studied the conditions under which coefficient alpha and 10 related internal consistency reliability coefficients underestimate the reliability of a measure. Simulated data showed that alpha, though reasonably robust when computed on n components in moderately heterogeneous data, can under certain conditions seriously underestimate the reliability of a measure. Consequently, alpha, w...
متن کاملTolerating faults while maximizing reward
The imprecise computation (IC) model is a general scheduling framework, capable of expressing the precision vs. timeliness trade-off involved in many current real-time applications. In that model, each task comprises mandatory and optional parts. While allowing greater scheduling flexibility, mandatory parts in the IC model have still hard deadlines and hence they must be completed before the t...
متن کاملA method to optimize the response range while maintaining Rorschach Comprehensive System validity.
Brief and lengthy Rorschach records have been identified as common problems in protocol administration. Clinicians have debated how to prevent overly short and long records, but they have been reluctant to alter standardized administration for fear of introducing bias. The present study examines a nonintrusive method for constraining responses by prompting for an extra response when only one is...
متن کاملMaximizing Library Presence While Minimizing Online Maintenance
This paper presents challenges and opportunities for an academic library to increasing its presence in an online learning management system (LMS). Successful examples from Athabasca University, Canada’s Open University will highlight the benefits of a collaborative team approach to course development and LMS software applications. This case study demonstrates how an academic library can partici...
متن کاملConvexifying Monotone Polygons while Maintaining Internal Visibility
Let P be a simple polygon on the plane. Two vertices of P are visible if the open line segment joining them is contained in the interior of P . In this paper we study the following questions posed in [5, 6]: (1) Is it true that every non-convex simple polygon has a vertex that can be continuously moved such that during the process no vertex-vertex visibility is lost and some vertex-vertex visib...
