Extending Applications of Generalizability Theory-Based Bifactor Model Designs

Bifactor Item Response Theory Model of Acute Stress Response

BACKGROUND Better understanding of acute stress responses is important for revision of DSM-5. However, the latent structure and relationship between different aspects of acute stress responses haven't been clarified comprehensively. Bifactor item response model may help resolve this problem. OBJECTIVE The purpose of this study is to develop a statistical model of acute stress responses, based...

Investigation of Bakhtiari Carpet Designs based on Kaplan-Gestalt Model

Therefore, recognizing the image in carpets can be a window into recognizing these ideals. In this research, Bakhtiari rug is investigated. Bakhtiari rugs (toranji, yalameh and cetral) are textiles produced by Bakhtiari people of choharmahal-o-bakhtiari province. T...

Generalizability Theory: Overview

36 Generalizability Theory

Generalizability (G) theory is a statistical theory for evaluating the dependability (or reliability) of behavioral measurements (Cronbach, Gleser, Nanda, & Rajaratnam, 1972; see also Brennan, 2001; Shavelson & Webb, 1991). G theory permits the researcher to address such questions as: Is the sampling of tasks or judges the major source of measurement error? Can I improve the reliability of the ...

Extending Role Based Access Control Model for Distributed Multidomain Applications

This paper presents the results related to the development of a flexible domain-based access control infrastructure for distributed Grid-based Collaborative Environments and Complex Resource Provisioning. The paper proposes extensions to the classical RBAC model to address typical problems and requirements in the distributed hierarchical resource management such as: hierarchical resources polic...
