From a signal processing point of view, the Gibbs phenomenon is the step response of a low-pass filter, and the oscillations are called ringing or ringing artifacts. Truncating the Fourier transform of a signal on the real line, or the Fourier series of a periodic signal (equivalently, a signal on the circle), corresponds to filtering out the ...
Engestrom identifies three generations of activity theory and associated researcher: first generation, a model focused on the individual (subject-object-mediating artifact) by Lev Vygotsky (1978); second generation, expansion of the model to include collective action, by Alexei Leont'ev (1981); and third generation, toward a networked ...
The main cause of ringing artifacts is overshoot and oscillations in the step response of a filter.. The main cause of ringing artifacts is due to a signal being bandlimited (specifically, not having high frequencies) or passed through a low-pass filter; this is the frequency domain description.
In reviewing the older leadership theories, Scouller highlighted certain limitations in relation to the development of a leader's skill and effectiveness: [3] Trait theory: As Stogdill (1948) [4] and Buchanan & Huczynski (1997) had previously pointed out, this approach has failed to develop a universally agreed list of leadership qualities and "successful leaders seem to defy classification ...

Another model that has emerged in the trait leadership literature is the Integrated Model of Leader Traits, Behaviors, and Effectiveness. [3] This model combines traits and behaviors in predicting leader effectiveness and tested the mediation effect of leader behaviors on the relationship between leader traits and effectiveness.

Good leadership analysis is not reductionist, but rather takes into consideration the overall person in the context of the times, society and culture from which they come.
