The Brief Electricity and Magnetism Assessment BEMA , developed by Chabay and Sherwood, was designed to assess student understanding of basic electricity and magnetism concepts covered in college-level calculus-based introductory physics courses. To evaluate the reliability and discriminatory power of this assessment tool, we performed statistical tests focusing both on item analyses item diffi...

In this paper we are interested in Hochschild cohomology of finite-dimensional algebras; the main motivation is to generalize group cohomology to larger classes of algebras. If suitable finite generation holds, one can define support varieties of modules as introduced by [SS]. Furthermore, when the algebra is self-injective, many of the properties of group representations generalize to this set...

Lord (1980) proposed formulas that provide direct relationships between IRT discrimination and difficulty parameters and conventional item statistics. The purposes of the present study were to determine (1) the veracity of the two formulas within the context that Lord proposed, and (2) the robustness of the formulas beyond the initial and restrictive conditions identified by Lord. Simulation an...

This study was conducted to develop "Environmental Scale for Children”. 106 children between 48-72 months participated in the pilot study. The scale concluded after statistical analysis of findings. Statistical analyzes “Environmental Children” data were carried out using ITEMAN statistics program. Item discrimination difficulty index calculations calculated as biserial correlation coefficient....

As the business environment and its workforce’s composition have become more diversified, attention has been paid to cultural intelligence or ability effectively function in such an environment. Various attempts made measure develop leaders staff members’ intelligence. The Cultural Intelligence Scale (CQS) is most representative tool for measuring worldwide frequently used South Korea. Although...

energy equation for turbulent flow in a rotating system was derived in terms of second order correlation tensors, where the correlation tensors were functions of space coordinates, distance between two points and time. to reveal the relationship of turbulent energy between two points, one point was taken as origin of the coordinate system. due to rotation, the coriolis force played an important...

Abstract Birge Huisgen-Zimmermann calls a finite dimensional algebra homologically tame provided the little and big finitistic dimension are equal finite. The question formulated in title has been discussed by her paper “Representation-tame algebras need not be tame”, looking for any r ≥ 1 at sequence of Λ m with + . As we will show, also is It follows that contrary to assertion, all tame.
