What are the mechanisms leading to this performance?The first impression is that centers are

places of excellence and create the conditions for good work

Alternative hypotheses◦People that are already doing good work

before centers exist are later recruited to centers Centers represent regrouping and concentration of

existing human resources◦Centers train young researchers to be stars

Center creation: 6 in 2001; 1 in 2002; 1 in 2003; 6 in 2004; 1 in 2006.

10/24-28/2012


MethodCompiled list of individual authors

for each cohort from 1998 to 2006 for the entire field of nanotechnology

Compiled cumulated citations at 2008 (and 2010) for each author

Same procedure for papers reported by NSECs

Matched names of NSEC authors to field level in each cohort

10/24-28/2012


Method (continued)Constructed “sliding window” of NSEC

author appearance for NSEC cohorts 2001-2006 in each field level cohort 1998-2006

Each cohort of papers at field level starting at 1998 is fixed reference

Each cohort of papers for all centers contrasted sequentially against the “fixed” field cohort

As the center cohorts “slide” the transition from field to center is detected

Method to Detect New “Stars”Took each NSEC cohort from

2001 as fixed referenceTracked authors for earlier field

level cohorts starting at 1998Determined authors in field who

had not published prior to doing so with NSEC

Reveals all authors new to the field through publishing as a member of an NSEC

Implications for Center Policy NSEC publication and citation growth rate is

associated with two things:◦ Recruitment of leading scientists already having high

impact on the field. ◦ Development of novice researchers who are highly

productive and have high impact Successive waves of new centers:

◦ Recruit more leading researchers that were not brought in by earlier centers.

◦ Develop their own new “stars” NSECs represent an obvious redistribution of human

resources in the field with greater concentration in a few places.

At the same time they develop new “star quality” talent at a very impressive rate
