Item Open Access Role of lipooligosaccharide in the attachment of Moraxella catarrhalis to human pharyngeal epithelial cells(Wiley, 2005) Akgul, G.; Erturk, A.; Turkoz, M.; Turan, T.; Ichinose, A.; Nagatake, T.; Ahmed, K.The goal of this study was to determine the role of lipooligosaccharide in the attachment of Moraxella catarrhalis to human pharyngeal epithelial cells. Strain 2951 and its Pk mutant strain 2951 galE were used in this study. This study suggests that the Pk epitope of LOS is not an adhesin for M. catarrhalis, but plays a crucial role by its surface charge in the initial stage of attachment.Item Open Access Two to Tango? A cross-cultural investigation of the leader-follower agreement on authoritarian leadership(Elsevier, 2021-03-02) Karakitapoglu-Aygün, Zahide; Tomruk Gümüşlüoğlu, Lale; Erturk, A.; Scandura, T. A.This study investigates how the leader–follower agreement on authoritarian leadership influences the quality of communication experience with the leader across three countries: Taiwan, Turkey, and the U.S. We also examine the mediating role of the quality of communication in linking agreement on authoritarianism to subordinate in-role and extra-role performance. Our sample consisted of 674 Taiwanese, 409 Turkish, and 294 American employees and their leaders. The results demonstrate that in the U.S., the leader–follower agreement on this negative form of leadership has positive effects on the quality of communication. In Turkey, however, the leader–follower agreement on high levels of authoritarian leadership has a negative effect on interpersonal interactions. In Taiwan, agreement or disagreement on authoritarian leadership is not as important as in the U.S. or Turkey. We also found that the quality of communication experience was a significant mediating mechanism between the leader–follower agreement and follower performance in all three countries.
