Powerful or powerless? Beyond power and powerlessness: the Leipzig Leadership Model provides some answers

Power Politics and the Powerless

Unstable power threatens the powerful and challenges the powerless: evidence from cardiovascular markers of motivation

Possessing social power has psychological and biological benefits. For example, during task interactions, people high in power are more likely to display a benign cardiovascular (CV) response pattern indicative of "challenge" whereas people low in power are more likely to display a maladaptive CV pattern indicative of "threat" (Scheepers et al., 2012). Challenge is marked by high cardiac output...

The Story of The Hot Hand: Powerful Myth or Powerless Critique?

Thomas Gilovich and Amos Tversky famously claimed that the belief in the Hot Hand in basketball is a cognitive illusion, an instance of the belief in the Law of Small Numbers. They supported this claim with a variety of orthodox statistical tests failing to show any clear evidence of a Hot Hand phenomenon. These researchers neglected to perform any power analysis on this test. Here we show that...

Renormalising Nn Scattering: Is Power Counting Powerless?

The renormalisation of NN scattering in theories with zero-range interactions is examined using a cut-off regularisation where the cut-off is taken to infinity, dimensional regularisation (DR) with minimal subtraction, and DR with powerdivergence subtraction. In the infinite cut-off limit power counting breaks down: terms of different orders in the potential contribute to the scattering amplitu...
