    Sorting Through and Sorting Out: The State of Content Sharing in the E-Learning

    On 22-24 September 2002, a group of 22 education and information technology specialists gathered on the campus of the University of California at Irvine (UCI), for a symposium on the state of educational "content sharing." (See participant list.) The meeting was sponsored by the William and Flora Hewlett Foundation Education Program and the UCI Distance Learning Center. This paper summarizes the themes that emerged from that gathering. Most papers can be characterized as collaborative, but this one is particularly deserving of that adjective. The presentation here is an attempt to synthesize the ideas of all the participants, expressed in numerous conversational and written exchanges pre-, during and post-meeting. While every effort has been made to present the range of views, surely not all participants would agree with the emphases and interpretations herein.This report includes a hyper-linked bibliography and footnotes for additional web-based material on e-learning topics.

    Open Educational Content for Digital Public Libraries

    If the production of digital content for teaching -- particularly free content -- is to expand substantially, there must be mechanisms to establish a link to fame and fortune that was not perceived in a pre-digital world. How that might be done is the central question this report addresses, in the context of examining the movement for open educational content. Understanding that movement requires delving into the history of what may seem, on first pass, a totally unrelated field of endeavor. The reader's patience is requested....

    Further evidence on the size and power of the Bierens and Johansen cointegration procedures

    Although both the Johansen (1991, 1994) trace test and Bierens (1997a,b) nonparametric lambda-min test for cointegration have good size properties in Monte Carlo studies by Hubrich, Lutkepohl, and Saikkonen (2001) and Boswijk, Lucas, and Taylor (2000), the Bierens test has very low power. In contrast, Bierens reports good power for his procedure. Meanwhile, Hubrich et al. and Boswijk et al. do not include Bierens' companion method for estimating the number of cointegrating vectors, nor do they investigate the effect of serial correlation on Bierens'' test. In the present paper, inclusion of the estimation step does not significantly degrade size of the Bierens procedure, even with serial correlation, but power is not improved. Serial correlation does degrade the size of the Johansen test, but it remains superior. Analysis of Bierens'' (1997b) Monte Carlo results suggests that their indication of high power reflects the test''s lack of scale invariance.Monte Carlo
