Constructing a Test Network with a Rasch Measurement Model

The Rasch Model for Test Construction and Person Measurement

Revenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model

The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...

A New Approach for Constructing Pore Network Model of Two Phase Flow in Porous Media

Development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. In this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. Af...

constructing a test to predict the translation performance of english translation ma graduates on legal correspondence and deeds as a profession

regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...

Constructing indices representing supportiveness of the physical environment for walking using the Rasch measurement model

BACKGROUND The objectives of this study were to use the Rasch model to 1) assess the psychometric properties of a physical environmental audit instrument and 2) to develop indices of interrelated environmental attributes that summarize environmental supportiveness for walking. METHODS A set of items were derived representing two conceptual physical environmental constructs: 1) functional/safe...
