Drawing on conservation of resources theory, we hypothesize that political behavior mitigates the adverse effect of perceived organizational politics on task performance via psychological empowerment, yet exacerbates its adverse effect on task performance via emotional exhaustion. Three-wave multisource data from a sample of 222 employees and their 75 supervisors were collected for hypothesis testing. Findings supported our hypotheses. Our study enhances understandings of the complex resource dynamics of using political behavior to cope with perceived organizational politics and highlights the need to move stress-coping research from a focus on the stress-buffering effect of coping on outcomes to a focus on the underlying competing resource dynamics.

It is of growing concern that supervisors sometimes engage in destructive leadership behavior to undermine their subordinates, which exacts a psychological toll on these employees. How can employees mitigate and overcome the adverse psychological effects of supervisor undermining? Invoking theories of personal agency and social competencies, this study addresses this important question by examining the effectiveness of employee voice in buffering the adverse effects of supervisor undermining on employee work-related wellbeing and turnover intention. Through a three-wave field study, we found that voice plays a buffering role in the relationship between supervisor undermining and these outcome variables only when employees possess high levels of political skill (i.e., three-way interactions), and that this buffering effect is realized through mitigating the adverse effects of supervisor undermining on employee psychological empowerment. In contrast, when employees possess low levels of political skill, engaging in high levels of voice exacerbates the detrimental effects of supervisor undermining on employee psychological empowerment, and subsequently decreases employee work-related wellbeing and heightens employee turnover intention. The theoretical and practical implications of our findings are discussed.

To keep an intellingent vehicle on the lane in the vision-based navigation, an image processing technology is proposed to detect the lane of astructured road. A way of lane marking recognition arithmetic being acclimated to structuring road is put forward. It makes use of Soble morphology gradient algorithm to coordinate with Hough transform, and we used straight line to reconstruct 2D lane. As the test result, it proves that the system can fairly exactly detect the normative real-time lane lines and identify some important information.
