A beta hairpin is a common supersecondary motif composed of two anti-parallel beta strands connected by a loop. The structure resembles a hairpin and is often found in globular proteins. The loop between the beta strands can range anywhere from 2 to 16 residues. However, most loops contain less than seven residues. [2]
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 ...
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 ...
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 ...
Consideration and initiating structure are two dimensions of leader behavior identified in 1945 as a result of the Ohio State Leadership Studies. Reviews of research on these dimensions are described in Stogdill's Handbook of leadership: A survey of theory and research and Littrell's Explicit leader behaviour .
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.
Transactional leadership (or transactional management) is a type of leadership style that focuses on the exchange of skills, knowledge, resources, or effort between leaders and their subordinates. This leadership style prioritizes individual interests and extrinsic motivation as means to obtain a desired outcome.
For example, the β-hairpin motif consists of two adjacent antiparallel β-strands joined by a small loop. It is present in most antiparallel β structures both as an isolated ribbon and as part of more complex β-sheets. Another common super-secondary structure is the β-α-β motif, which is frequently used to connect two parallel β-strands.
