Introduction: The present study aimed to investigate the psychometricproperties of Grasha-Riechmann Student Learning Styles Scale.Method: The participants included 1039 students (421 students in human and 618 students in technical sciences), selected through the stratified sampling method from Tehran University. They answered the Grasha-Riechmann student learning style scale and the data was an...

Factor analysis includes both component analysis and common factor analysis. More than other statistical techniques, factor analysis has suffered from confusion concerning its very purpose. This affects my presentation in two ways. First, I devote a long section to describing what factor analysis does before examining in later sections how it does it. Second, I have decided to reverse the usual...

The geography of innovation is built upon an agglomeration of economies and “innovation hearths”, (Crevosier, 2004). Innovative success of a firm is often indicated by their creativity, access to alliances, and usage of access to local resources. Few metrics have been able to give adequate rise to a definition for Innovation as a means of measuring entrepreneurial and innovative success in comb...

This study demonstrates that a commonly used type of factor analysis, principle components analysis, contributes to the amount of error in statistical analysis. In the study, which concerns email use, factor analyses were performed using several different factor analysis methods. The results show that using factors derived via principle components analysis as dependent variables substantially i...

The analysis of all Casimir force experiments using a sphere-plate geometry requires the use of the proximity-force approximation (PFA) to relate the Casimir force between a sphere and a flat plate to the Casimir energy between two parallel plates. Because it has been difficult to assess the PFA's range of applicability theoretically, we have conducted an experimental search for corrections to ...

Investigations into the gait of persons with partial foot amputation (PFA) suggest that the effective foot length can be restored when the prosthesis incorporates a relatively stiff forefoot, restricts dorsiflexion, and includes a mechanism whereby forces caused by loading the toe lever can be comfortably distributed to the leg (e.g., an anterior tibial shell). The purpose of this investigation...

Introduction: Profunda femoris artery (PFA) normally originates from posterolateral aspect of femoral artery and circumflex arteries arise from profunda femoris artery near its origin. As femoral artery (FA) & PFA are commonly assessed for various procedures for diagnosis and treatment for many diseases, knowledge of its course and branching pattern is very important for clinicians to prevent c...
