The Development of Corporate Identity: A Political Perspective

A corporate identity denotes a set of attributes that senior managers ascribe to their organization. It is therefore an organizational identity articulated by a powerful interest group. It can constitute a claim which serves inter alia to justify the authority vested in top managers and to further their interests. The academic literature on organizational identity, and on corporate identity in particular, pays little attention to these political considerations. It focuses in an apolitical manner on shared meanings when corporate identity works, or on cognitive dissonance when it breaks down. In response to this analytical void, we develop a political analysis of corporate identity and its development, using as illustration a longitudinal study of successive changes in the corporate identity of a Brazilian telecommunications company. This suggests a cyclical model in which corporate identity definition and redefinition involve power relations, resource mobilization and struggles for legitimacy. © Blackwell Publishing Ltd 2007.

Antimicrobic susceptibility and plasmid profile analysis as identity tests for multiple blood isolates of coagulase-negative staphylococci

We compared a disk diffusion antimicrobic susceptibility panel with plasmid DNA profiles as tests for identity of 106 isolates of coagulase-negative staphylococci cultured from the blood of 45 patients on multiple occasions. The antimicrobic panel included penicillin, oxacillin, clindamycin, trimethoprim-sulfamethoxazole, chloramphenicol, tetracycline, tobramycin, kanamycin, and gentamicin. Nineteen patterns of antimicrobic susceptibility were found. The most common pattern was present in 25% of the isolates, and at least one isolate from 31% of the patients had this pattern. Forty-seven distinct plasmid DNA profiles were found. The most common plasmid profile was present in 8.5% of the isolates, and at least one isolate from 15% of the patients had this profile. Twenty-eight patients had multiple isolates that were identical by plasmid profile analysis. Twenty-seven (96%) of these patients had isolates that were also identical by antimicrobic susceptibility. Nineteen patients had multiple isolates that were different by plasmid profile analysis. In 18 (95%) of these patients, the isolates were also different by antimicrobic susceptibility. Although plasmid DNA profile analysis is a more discriminating tool, these data confirm that a selected disk diffusion antimicrobic susceptibility panel may be used to screen multiple blood isolates of coagulase-negative staphylococci for identity or differences.
