However it took another 10 years before the theory could be applied to the problem of the Klein paradox. In 1941 Friedrich Hund showed that, [8] under the conditions of the paradox, two currents of opposite charge are spontaneously generated at the step. In modern terminology pairs of electrons and positrons are spontaneously created the step ...
Klein paradox: When the potential of a potential barrier becomes similar to the mass of the impinging particle, it becomes transparent. Mott problem , also known as the Mott paradox: [ 5 ] Spherically symmetric wave functions, when observed, produce linear particle tracks.
Klein is also credited for inventing the idea, part of Kaluza–Klein theory, that extra dimensions may be physically real but curled up and very small, an idea essential to string theory. In 1938, he proposed a boson-exchange model for charge-charging weak interactions (radioactive decay), a few years after a similar proposal by Hideki Yukawa.

The Integrated Psychological Theory of leadership attempts to integrate the strengths of the older theories (i.e. traits, behavioral/styles, situational and functional) while addressing their limitations, introducing a new element – the need for leaders to develop their leadership presence, attitude toward others, and behavioral flexibility ...
Functional leadership theory (Hackman & Walton, 1986; McGrath, 1962) is a theory for addressing specific leader behaviors expected to contribute to organizational or unit effectiveness. This theory argues that the leader's main job is to see that whatever is necessary to group needs is taken care of; thus, a leader can be said to have done ...
On the individual level of analysis, scholars have mostly used paradox theory to explain how individuals manage the competing demands of exploration and exploitation. [8] [9] Paradoxical leadership refers to seemingly competing, yet interrelated behaviors to meet structural and follower demands simultaneously and over time. [10]
My family adores pot stickers and dumplings. And they're a great quick meal. A few years ago I started freezing leftover rice in a resealable bag, adding to it whenever I had any left from dinner.
