?Dear all,
I’ve used UCINET to run Davis_SouthernWomen data, using 2-mode categorical core-periphery. As the attached output shows, the core events are 7, 8, and 9.

But these results seem different from the ones if using xUCINET (via xDualCorePeriphery function), which showed that the core events are 5,6, 7,8 and 9.

Hi

Dual core periphery in UCINET uses the categorical method whereas xUCINET uses the dual projection which is a continuous method. The later and usually better method is the dual projection. This can be done in UCINET but requires a few extra steps but gets the same results see?

for details how to do this inUCINET.

Hi

I vaguely recall an error in the Davis data that was corrected and this could cause the change. Also we do update and improve routines and correct bugs and these too could make a difference.?

Hi Martin,

Thanks! That’s really helpful.

?

I tried the dual-projection method, following the steps mentioned in the document. There are indeed 5 core events now. But the women-by-women partition generated 10 core members, rather than 8 as described in the book (Figure 13.5, Analyzing Social Networks). I followed the settings (including Minres as algorithm) when doing the one-mode continuous core-periphery. The transformed one-mode data and the output are as attached.

?

Not sure what caused this discrepancy? ?
