Emerging bicycle tourism and the theory of planned behavior

In this study, we investigated the process of travelers’ decision formation for bicycle touring as a form of sustainable tourism activity. We extended the theory of planned behavior (TPB), using personal norm and past behavior as predictors and the attractiveness of unsustainable alternatives as a moderator. Results of the modeling comparison showed that our extended TPB model was superior to the original TPB in predicting intention. Our results from the structural analysis revealed that the hypothesized paths linking attitude, subjective norm, perceived behavioral control, personal norm, and intention were supported; and personal norm significantly mediated the impact of subjective norm on intention. Moreover, our proposition that bicycle travelers’ decision-making process would differ based on their level of the attractiveness of unsustainable alternatives was generally supported. Overall, our results help us clearly understand the role of volitional and non-volitional processes, personal norm, past behavior, and the attractiveness of unsustainable alternatives in explaining the intention formation of bike traveling.     

Exploring how and when ethical conflict impairs employee organizational commitment: A stress perspective investigation

Previous studies demonstrate the detrimental effect of ethical conflict (i.e., incompatibility between ethical values of employees and organizations) on employee organizational commitment. However, few studies have assessed the underlying mechanisms and boundary conditions that may contribute to a deeper understanding of how and when the detrimental effect manifests. Drawing on the transactional model of stress and literature on the moral self, our study examines the psychological strain as a key intermediate mechanism that channels the negative relationship between the ethical conflict and organizational commitment. Furthermore, we posit that employees with different levels of moral identity and moral efficacy may suffer differently from ethical conflict. We tested our research model with two-wave lagged data obtained from 265 healthcare employees and found that the indirect, negative effect of ethical conflict on organizational commitment via psychological strain is strongest among employees with high moral identity and low moral efficacy. Interestingly, results show that employees with low moral identity and high moral efficacy do not suffer from ethical conflict. These findings suggest that ethical conflict is differentially harmful to employees and that a more nuanced understanding of its contingent effects is needed.

The Joint Effects of Multiple Legal System Characteristics on Auditing Standards and Auditor Behavior

This paper derives the impacts of legal system characteristics and auditing standards on auditor behavior (audit quality), and analyzes the determination of optimal auditing standards under different legal regimes. Legal regimes are characterized by differences in the uncertainty concerning the outcome of legal proceedings (termed vagueness of legal systems) and differences in the average size of damage awards. Auditing standards as determined by standard setters can vary in both toughness and vagueness. Our analysis provides implications for the adoption of International Standards on Auditing (ISA). Countries, such as the United States, where auditor legal liability is significantly more onerous than the global norm are not likely to adopt ISA, since these standards may not induce auditors to provide the optimal level of audit quality. Conversely, the adoption of ISA by countries, such as China, where the legal system makes the recovery of damages from auditors quite difficult, is not by itself likely to result in a high level of audit quality. Furthermore, our model suggests that auditor rotation can help improve audit quality, but only in certain circumstances.
