Item does not contain fulltext, While most of the workplace bullying research has focused on targets and the devastating consequences they face from being exposed to such negative behaviour, bullying does not occur in a social vacuum. Previous research has suggested that people who are exposed to bullying sometimes engage in such behaviour themselves. In this paper, we wanted to test the reciprocal nature of bullying behaviour over time and potential moderators of this relationship in two studies. In Study 1, using two-wave full panel data, we test whether bullying exposure predicts bullying enactment and vice versa. In Study 2, using another two-wave dataset, we test whether individual coping styles moderate the relationship between bullying exposure and enactment. The results of the two studies provide support for the reciprocal nature of bullying behaviour and show that employees who tend to cope actively and instrumentally with being exposed to bullying have a higher chance of engaging in bullying. The reverse holds for people who tend to cope by disengaging and talking to others. This study has important implications for both the bullying literature and for practitioners working on bullying prevention and resolution.

Item does not contain fulltext, Previous research has demonstrated the crucial association between employee stressors and workplace bullying. In this article, we argue that a nurturing organizational context will protect employees from exposure to workplace bullying and will interact with individual demands and resources known to have effect on exposure to bullying in the workplace. In specific, we look at high-involvement work practices (HIWPs) - which include participation, information-sharing, competence development, and rewards. Multilevel analyses on the data from 28,923 Belgian employees from 144 organizations show that organization-level HIWPs are negatively associated with bullying exposure. Moreover, HIWPs interact with individually experienced job demands and resources, by decreasing the association between employee work pressure and bullying and by somewhat compensating for the lack of experienced social support from colleagues at work. HIWPs did not moderate the relationship between employee job insecurity and bullying and social support from the supervisor and bullying. These findings highlight the important role HIWPs can play in protecting employees from workplace bullying, while also suggesting the difficulty of compensating for certain individual risk factors.

BBuoyancy-driven turbulent mixing of fluids of slightly different densities [At = ¿¿/(2 ) = 1.15×10-2] in a long circular tube tilted at an angle ¿ = 15° from the vertical is studied at the local scale, both experimentally from particle image velocimetry and laser induced fluorescence measurements in the vertical diametrical plane and numerically throughout the tube using direct numerical simulation. In a given cross section of the tube, the axial mean velocity and the mean concentration both vary linearly with the crosswise distance z from the tube axis in the central 70% of the diameter. A small crosswise velocity component is detected in the measurement plane and is found to result from a four-cell mean secondary flow associated with a nonzero streamwise component of the vorticity. In the central region of the tube cross section, the intensities of the three turbulent velocity fluctuations are found to be strongly different, that of the streamwise fluctuation being more than twice larger than that of the spanwise fluctuation which itself is about 50% larger than that of the crosswise fluctuation. This marked anisotropy indicates that the turbulent structure is close to that observed in homogeneous turbulent shear flows. Still in the central region, the turbulent shear stress dominates over the viscous stress and reaches a maximum on the tube axis. Its crosswise variation is approximately accounted for by a mixing length whose value is about one-tenth of the tube diameter. The momentum exchange in the core of the cross section takes place between its lower and higher density parts and there is no net momentum exchange between the core and the near-wall regions. A sizable part of this transfer is due both to the mean secondary flow and to the spanwise turbulent shear stress. Near-wall regions located beyond the location of the extrema of the axial velocity (|z|¿0.36 d) are dominated by viscous stresses which transfer momentum toward (from) the wall near the top (bo
