Leader Role Inversion as a Corollary to Leader-Member Exchange

Leader emergence: the case of the narcissistic leader.

These studies investigate whether individuals with high narcissism scores would be more likely to emerge as leaders during leaderless group discussions. The authors hypothesized that narcissists would emerge as group leaders. In three studies, participants completed personality questionnaires and engaged in four-person leaderless group discussions. Results from all three studies reveal a link b...

Leader self-definition and leader self-serving behavior

The present research investigated the relationship between leader self-definition processes and leader self-serving behaviors. We hypothesized that self-definition as a leader interacts with social reference information (descriptive and injunctive) in predicting leader self-serving actions. Six studies (i.e., two laboratory experiments, two scenario experiments, and two crosssectional surveys) ...

Trypanosome mRNAs have unusual "cap 4" structures acquired by addition of a spliced leader.

A single capped oligonucleotide is released from Trypanosoma brucei poly(A)+ RNA upon digestion with RNase T2. This observation supports the hypothesis that all T. brucei mRNAs share a common leader sequence. Digestion of the T2-resistant species with nucleotide pyrophosphatase shows that the capping nucleotide is 7-methylguanosine 5'-monophosphate (pm7G). Additional characterization of the T2-...
