From the perspective of leader-member exchange (LMX) theory, we investigated how two forms of leadership style (uniform LMX (ULMX) and differential LMX (DLMX)) impact member participation in SOVCs. Furthermore, based on computer simulations we also examine the extent to which several contextual factors moderate the relationship between leadership style and member contributions. The key findings...
Temperature-gradient microstructure and nutrient profiling were undertaken at both an inshore and an offshore site on Mono Lake, California, to determine whether boundary mixing occurred and the effects on nutrient flux within the lake. Turbulence, as quantified by rates of dissipation of turbulent kinetic energy, was two to three orders of magnitude higher at the inshore site where the pycnocl...
Large-eddy simulation (LES) is used to investigate how dominant breaking waves in the ocean under hurricane-force winds affect the drag and near-surface airflow turbulence. The LES explicitly resolves the wake turbulence produced by dominant-scale breakers. Effects of unresolved roughness such as short breakers, nonbreaking waves, and sea foam are modeled as the subgrid-scale drag. Compared to ...
the effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an acoustic doppler velocimeter (adv). the three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate qs/q0 = 2%located...
While scholarship on educational change has long accepted that disruptions to the status quo are an essential part of the change process, disruption has never been more central to planned change than it is in the current political context in the USA, where legislation has mandated school closure, reconstitution, and turnaround as required remedies for schools failing to produce annual student a...
A major challenge for managers in turbulent environments is to make sound decisions quickly. Dynamic capabilities have been proposed as a means for addressing turbulent environments by helping managers extend, modify, and reconfigure existing operational capabilities into new ones that better match the environment. However, because dynamic capabilities have been viewed as an elusive black box, ...
Turbulent kinetic energy dissipation rates (ε) and eddy diffusion coefficients (K z) in the tropical mesosphere over Gadanki (13.5 • N, 79.2 • E), estimated from Doppler widths of MST radar echoes (vertical beam), observed over a 3-year period, show a seasonal variation with a dominant summer maximum. The observed seasonal variation of ε and K z in the mesosphere is only partially consistent wi...
Traditional studies of animal navigation over both long and short distances have usually considered the orientation ability of the individual only, without reference to the implications of group membership. However, recent work has suggested that being in a group can significantly improve the ability of an individual to align toward and reach a target direction or point, even when all group mem...
[1] Variations of atmospheric CO2 at regional scales are becoming increasingly important in understanding regional carbon budgets, yet the processes that drive them remain relatively unexplored. A simulation was conducted to test a coupled biosphereatmospheric model (SiB2-RAMS), by comparing with measurements made at the WLEFTV tower in Wisconsin, and to investigate some of the mechanisms leadi...
Recent observations of biologically generated turbulence in the ocean have led to conflicting conclusions regarding the significance of the contribution of animal swimming to ocean mixing. Measurements indicate elevated turbulent dissipation—comparable with levels caused by winds and tides—in the vicinity of large populations of planktonic animals swimming together 1. However, it has also been ...
