Information Literacy and the Evolving MBA Degree

MBA program curriculums have been the target of criticism since the financial scandals of the early 2000s, with the main focus being that many programs sacrificed the teaching of useful, real world skills in favor of impractical scientific research, while also neglecting areas such as ethics and social responsibility. The financial collapse prompted many MBA programs to implement reforms which include adding experiential learning programs among other changes. These reforms provide opportunities for librarians to introduce or increase information literacy components in the programs. The current state of MBA information literacy practices is discussed, with several initiatives highlighted and some new approaches suggested.     

参量匹配滤波器和向量自回归滤波器的等价性

分析了自适应匹配滤波器和向量自回归(VAR)时域白化滤波器. 结果表明,通过最小化用误差平方之和估计的均方误差得到的参量滤波器系数和通过相同阶数的多通道最小二乘法得到的VAR滤波器系数是等价的. 此外,还分析了VAR滤波器最小二乘估计器的渐进性能,分析了滤波器的运算量和杂波抑制性能.

The Donkey of the Prophet in Shī‘ite Tradition

The present study examines the treatment of the Prophet's mount in Shī‘ite tradition. We discuss the different opinions concerning the ass's name, ‘Ufayr or Ya‘fūr and present various traditions concerning utterances spoken by it, including utterances addressed to the Prophet, and other cases of human-like behaviour on its part, such as an ability to distinguish Muslims from Jews. We then go on to compare the Prophet's ass to those of other prophets, and find a number of similarities between them, in particular their ability to speak a human language. We also discuss the ass's death, which according to Shī‘ite tradition was by suicide, occasioned by the ass's fear following his master's death that someone else, not a prophet, would use it as a mount. We compare the Prophet's ass to those of Noah, and Solomon's Hoopoe, and show how Shī‘ite tradition has focused on similarities among them and utilized those to support the idea of the Imāmate as the Prophet's legacy in Shī‘ite doctrine. We further discuss the preference which Shī‘ite Imāms had for asses as against other mounts, a preference based on their wish to follow in the Prophet's footsteps.
