The aim of the research is to investigate how managers' personal traits, emotions and attitudes shape their tolerance of ambiguity (TOA); and consequently, the influence of managers' ambiguity tolerance in organizations' financial performance.

Survey data were collected from 54 Greek banks. A total of 412 senor-level managers completed questionnaires examining TOA, personal traits, emotions and attitudes in the workplace. Principal components analysis and ordinary least-squares regressions were used to explore the hypotheses of the paper.

Three factors characterize managers' emotions in the workplace, namely pleasure, arousal and dominance; and, respectively, two factors their involvement, namely importance and interest. Further, locus of control, importance, job satisfaction, pleasure and organizational commitment critically affect managers' TOA, which, in turn, seems to influence positively organizations' profitability.

Further research is required in Greek banking industry regarding the influence of managers' emotional and cognitive attributes in organizations' financial performance. Likewise, this research should be expanded to other industries.

The findings provide further support on the significance of emotional and cognitive attitudes in the workplace; the paper suggests policies to enhance managers' TOA, and thus, organizations' profitability.

The originality of this study lies in the finding that emotional and cognitive characteristics affect managers' TOA, which, in turn, influences significantly organizations' profitability. Another significant contributing factor is that the study is carried out in Greece, where few studies have been conducted in this area.

The aim of this research is to investigate the influence of hybrid knowledge management in workers' productivity and tolerance of ambiguity.

The research was conducted before and after the implementation of the Communication and Knowledge Motivator (CKM) model in Hellenic Railways Organization (2004 and 2008). Survey data were collected from 352 workers. In the first phase (2004), workers' productivity, ambiguity tolerance and demographical characteristics were examined. In the second phase (2008), the same measurements were performed. Ordinary regressions (enter and stepwise) were used to explore the research hypotheses.

The paper finds that workers' productivity and tolerance of ambiguity is positively affected by the CKM model. Further, it confirms the significant influence of workers' ambiguity tolerance in their productivity, before and after the implementation of the CKM model.

Workers' productivity might be influenced by the Hawthorne effect or by other emotional/cognitive attitudes. There is no such earlier measurement in Greece to compare and appraise the research findings and overall, the CKM model. Further research needs to be conducted in the Greek public sector.

The research findings suggest that the CKM model affects positively workers' productivity and ambiguity tolerance. Additionally, they note that workers' tolerance of ambiguity affects significantly their productivity.

The originality of this study lies in the CKM model that may influence positively workers' productivity and ambiguity tolerance. The study was carried out in Greece where few relevant studies have been conducted.

The aim of the research is to investigate the influence of emotional attitudes towards change on managers' tolerance of ambiguity.

A total of 70 CEOs of Greek IT firms completed questionnaires examining tolerance of ambiguity, emotional attitudes towards change ambiguity and job satisfaction. Principal components analysis and ordinary regression analyses were used to explore the hypotheses.

The paper finds that three factors characterize managers' emotional attitudes towards change, namely dominance, arousal, and pleasure. Furthermore, it indicates that job satisfaction can be taken as a critical intervention variable that “energizes” managers' arousal (i.e. stimulation, excitement and frenzy) which, in turn, influences their tolerance of ambiguity.

Deeper and broader level of research is necessary in Greek IT industry regarding the influence of emotional attitudes on tolerance of ambiguity. Likewise, this research should be expanded to other industries.

The findings provide further support on the significance of emotional attitudes during change and the paper suggests policies to enhance managers' tolerance of ambiguity.

The originality of this study lies in the finding that job satisfaction energizes the arousal factor, which, in turn, influences significantly managers' tolerance of ambiguity. Another important contributing factor is that the study is carried out in Greece, where few studies have been conducted in this area.
