Workers into Managers: Developing Leadership Competence of Production Unit Managers

This study analyses the competence gaps of lower-level managers in a typical manufacturing plant in Germany that had recently introduced a teamwork structure. Results indicate that the managers have difficulties with their new leadership-related tasks. Higher levels of leadership competence are found to be associated with better acceptance as a manager by superiors, but not by subordinates, better interaction with both subordinates and superiors, and with higher job satisfaction. Finally, a quasi-experiment shows that a combination of workshops and individual coaching had measurable effects on leadership competencies and partly improved identification with the managerial role. In terms of methodology, a new format of self-assessments is suggested for a more valid measurement of competencies. --Leadership skills,first line managers,training,experiment

Ferroelectrically driven spatial carrier density modulation in graphene.

The next technological leap forward will be enabled by new materials and inventive means of manipulating them. Among the array of candidate materials, graphene has garnered much attention; however, due to the absence of a semiconducting gap, the realization of graphene-based devices often requires complex processing and design. Spatially controlled local potentials, for example, achieved through lithographically defined split-gate configurations, present a possible route to take advantage of this exciting two-dimensional material. Here we demonstrate carrier density modulation in graphene through coupling to an adjacent ferroelectric polarization to create spatially defined potential steps at 180°-domain walls rather than fabrication of local gate electrodes. Periodic arrays of p-i junctions are demonstrated in air (gate tunable to p-n junctions) and density functional theory reveals that the origin of the potential steps is a complex interplay between polarization, chemistry, and defect structures in the graphene/ferroelectric couple
