Methods in Educational Research: From Theory to Practice, 2nd Edition is written by three professors: Lodico, Spaulding, and Voegtle, who have devoted their time in teaching and researching in educational contexts at the College of Saint Rose. The primary purpose of this second edition is to not only equip students, especially graduate ones who would like to be effective educators, for basic techniques and instructional practices in educational contexts and related fields, but also assist students in developing a “broad and deep understanding of research methodologies” to evaluate, and improve their practices.

Using maximum function of density functions we provide the new princeple which very advantage to discriminate a element for different situations. Finding maximum function and computing Bayes error are considered. The two programs are written to compute.

We consider the mobility of a quasi-twodimensional electron gas in a GaP/AlP/GaP quantum well with a valley degeneracy g 1   for quantum well width L < Lc = 45.7 Å and a valley degeneracy of g 2   for quantum well width L > Lc = 45.7 Å. We calculate the mobility as a function of electron density for interface-roughness and impurity scattering with using different approximations for the local-field correction. In the case of zero temperature and Hubbard local-field correction our results reduce to those of [16]. We also study the dependence of resistivity on temperature and parallel magnetic field. The Seebeck coefficient as a function of electron concentration and quantum well width are also calculated.

Language, Culture, and Identity among Minority Students in China: The Case of the Hui is written by Yuxiang Wang, a curriculum scholar, who builds on the history of curriculum studies with his post-colonial multicultural study of the minority Chinese - Hui. Wang’s study is an excellent example in response to UNESCO policy, which encourages countries to protect the rights of ethnic minority populations and their languages. Wang’s work also has a huge contribution to engagement in international cross-cultural work in fields of education and curriculum studies.

Right to silence is a fundamental right of human beings in criminal proceedings and one of the most important measures to protect human rights in society. The right to remain silent had been prescribed for a long time in the Criminal Procedure Code of many countries and proved to be effective in ensuring the rights of persons in custody, accused or defendants in criminal proceedings. However, there has been plenty of opinions on the right to silence in Vietnam. Some support the legalization, some oppose while some other are worried about implementation difficulties. Perhaps this is because the connotation of the right to silence is not fully understood. This paper analyzes the origin and nature of the right to silence, thereby providing a more accurate view on the connotation of the right to silence.
