Big problems with ISI data reported by science editors

Got this in an email from one of my lists:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

This presumably will be drawing some attention shortly. It is a very disturbing report by editors from the Journal of Cell Biology and the Journal of Experimental Medicine who have joined with the Executive Director of the Rockefeller University Press in reporting their inability to verify published impact factors using data provided provided by ISI itself. Their fruitless efforts to replicate published impact factors for their own and other journals revealed numerous and serious errors in several data sets provided by ISI and call into question the validity of both ISI's dataset and their published impact factors. If the problems they encountered are widespread, then the host of evaluative decisions that rely at least in part on published impact factors are suspect. Published impact factors affect authors' decisions about manuscript submission, funding awards, and promotion and tenure. While critiques of the use of impact factors are quite common, this is the first serious question raised about the underlying validity of the data used to calculate impact factors and therefore the accurracy of the metrics that are published.

A life-or-death moment for cities: New York and other metropolises must protect themselves from pandemics or our future will be far less urban

COVID-19 has killed at least 19,000 New Yorkers and dealt a body blow with lasting consequences to the city. Two paths lie ahead. If pandemics become common, then not only New York City but all of America’s service-based economy faces a bleak future. If this terrible plague is a unique event, then things will eventually get almost back to normal. To save both the nation’s biggest and most productive metropolis and tens of millions of service jobs across the county, we must invest enormously to prevent future pandemics.
