Koplienko Spectral Shift Function on the Unit Circle

Communications in Mathematical Physics, 2011
The authors solve in the paper a question raised by \textit{F. Gesztesy}, \textit{A. Pushnitski} and \textit{B. Simon} [``On the Koplienko spectral shift function. I: Basics'', Zh. Mat. Fiz. Anal. Geom. 4, No. 1, 63--107 (2008; Zbl 1190.47016)] regarding a trace formula of Koplienko with summable spectral shift function.

A Commentary on Minority Health as a Paradigm Shift in the United States

American Journal of Health Promotion, 1995
In a special issue that [bcuses on "underserved" populations, many of the findings concern racial and ethnic minority populations. Although most members of racial and ethnic minority groups in the United States are employed, seeking appropriate health care, and continually ilnproving their quality of life, a disproportionate share of health problems ...

Unit Root Tests and Mean Shifts

1992
A mean shift can cause tests for a unit root to erroneously fail to reject the null hypothesis of the existence of a unit root. Perron (1990) and Hendry and Neale (1991) provide simulation evidence of this for (augmented) Dickey-Fuller tests in models without a time trend.
