Of his contributions, the development of Ramsey theory and the application of the probabilistic method especially stand out. Extremal combinatorics owes to him a whole approach, derived in part from the tradition of analytic number theory. Erdős found a proof for Bertrand's postulate which proved to be far neater than Chebyshev's original
Ramsey theory, named after the British mathematician and philosopher Frank P. Ramsey, is a branch of the mathematical field of combinatorics that focuses on the appearance of order in a substructure given a structure of a known size. Problems in Ramsey theory typically ask a question of the form: "how big must some structure be to guarantee ...
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 ...
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 ...
Complementing this situational theory of leadership, Murphy wrote that leadership does not reside in the person, and it usually requires examining the whole situation. [45] In addition to situational leadership theory, there has been growing support for other leadership theories such as transformational, transactional, charismatic, and ...
Leadership analysis is the art of breaking down a leader into basic psychological components for study and use by academics and practitioners. 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.
Perhaps the focus on JonBenét's pageant participation would be just as pronounced today, says Elizabeth Jeglic, a professor of psychology at the John Jay College of Criminal Justice. Likely many ...
Leader development is described as one aspect of the broader process of leadership development (McCauley et al., 2010). Leadership development is defined as the expansion of a group's capacity to produce direction, alignment, and commitment (McCauley et al.), in contrast to leader development which is the expansion of a one's ability to be effective in leadership roles and processes.
