  • We have studied the chemisorption of oxygen at room temperature on Fe layers deposited on Pt(111) substrates by using core-level X-ray photoelectron spectroscopy. It was found that the oxygen atoms are chemisorbed when the thickness of the Fe layers is not larger than 6 monolayers. Upon post-annealing, it was found that part of the chemisorbed atoms are desorbed at a temperature range 600 - 700 K, after which the intermixing between Fe and Pt atoms occurs. The overall trend of this intermixing was very similar to the Fe/Pt(111) surface without oxygen exposure. The remaining oxygen adatoms, the amount of which is about a half of the total, were found to be eventually desorbed from the surface upon post-annealing at 1000 K. The binding energy of this phase was higher than that of the oxygen atoms desorbed at lower temperatures by 1.3 eV.

  • While trust and commitment are core mediating variables for the purpose of maintaining the long-term relationship, in the context of the characteristics of company and the relationship performance of its members, there have been limited studies which explore as to how each of the dimensions has affects differently. The basic purpose of this study is to examine the relationship between an automobile manufacturer and its agencies. The main purpose of this study is to examine how each different dimension of trust and commitment on the automobile manufacturer has different mediating effects between the characteristics of company(organization characteristics, relationship characteristics) and relationship performance perceived by its agents. Another purpose is to investigate the mechanism by which the relationship performance of the agencies is improved. An empirical study surveying 115 sales office managers at a leading automobile manufacturer in Korea was conducted. An analysis of the collected data indicates that while the characteristics of company have a positive influence on the agencies' relational performance through the mediating role of both trust of benevolence and commitment, agencies' trust of their headquarter's benevolence has a different influence on the dimensions of commitment. Finally, the authors discussed some theoretical contributions and managerial implications. And then, they presented limitations of this study and the future research directions.
