Dispersed Teams

Organizations increasingly rely on virtual teams to access geographically dispersed expertise. Yet, team dispersion introduces challenges to team communication that may negatively influence team performance. Using a sample of 53 innovation teams representing a variety of geographic dispersion configurations from completely collocated to highly dispersed, we examined the moderating role of transformational leadership on the relationship between team dispersion, team communication, and team performance. Our findings suggest that while transformational leadership is effective in reducing the negative effects of dispersion in collocated teams or ones with low levels of geographic dispersion, it is less effective helping improve the performance of highly dispersed teams. This effect may be due to a transformational leader’s difficulty in facilitating team communication in highly dispersed teams, where his or her influence might actually have counterproductive effects. We discuss the implications of our findings for theory, future research, and practice.

Key Factor

Upgrading furfural (FAL) to cyclopentanone (CPO) is of great importance for the synthesis of high-value chemicals and biomass utilization. The hydrogenative ring-rearrangement of FAL is catalyzed by metal-acid bifunctional catalysts. The Lewis acidity is a key factor in promoting the rearrangement of furan rings and achieving a high selectivity to CPO. In this work, highly dispersed Pd nanoparticles were successfully encapsulated into the cavities of a Zr based MOF, UiO-66-NO2, by impregnation using a double-solvent method (DSM) followed by H2 reduction. The obtained Pd/UiO-66-NO2 catalyst showed a significantly better catalytic performance in the aforementioned reaction than the Pd/UiO-66 catalyst due to the higher Lewis acidity of the support. Moreover, by using a thermal treatment. The Lewis acidity can be further increased through the creating of missing-linker defects. The resulting defective Pd/UiO-66-NO2 exhibited the highest CPO selectivity and FAL conversion of 96.6% and 98.9%, respectively. In addition, the catalyst was able to maintain a high activity and stability after four consecutive runs. The current study not only provides an efficient catalytic reaction system for the hydrogenative ring-rearrangement of furfural to cyclopentanone but also emphasizes the importance of defect sites.
