TL;DR: In this paper, the authors argue that role expectations have the potential to both enable and constrain middle manager strategic agency, and propose a reciprocal view of strategic role expectations, which elucidates the tensions between dialogue, legitimacy and rationality within a set of strategic roles.
Abstract: Based on an analysis of 262 interviews, I argue that role expectations have the potential to both enable and constrain middle manager strategic agency. To explain why the same role expectations have contradictory effects on agency, I analyse enabling conditions corresponding to four strategic role expectations, based on Floyd and Wooldridge's work on middle manager roles. After presenting eight enabling conditions for strategic agency, specific to the four role expectations, I argue that the dominant functionalist view of strategic roles should be augmented from a middle manager viewpoint. I suggest a reciprocal view of strategic role expectations, which elucidates the tensions between dialogue, legitimacy and rationality within a set of strategic roles.

14 Jun 2009TL;DR: The results show that cellular service can be effectively guaranteed while having a comparable sum rate with a none power control case in most of the cell area.
Abstract: We address resource sharing of the cellular network and a device-to-device (D2D) underlay communication assuming that the cellular network has control over the transmit power and the radio resources of D2D links. We show that by proper power control, the interference between two services can be coordinated to benefit the overall performance. In addition, we consider a scenario with prioritized cellular communication and an upper limit on the maximum transmission rate of all links. We derive the optimum power allocation for the considered resource sharing modes. The results show that cellular service can be effectively guaranteed while having a comparable sum rate with a none power control case in most of the cell area.

TL;DR: The field-emission characteristics of NanoBuds suggest that they may possess advantageous properties compared with single-walled nanotubes or fullerenes alone, or in their non-bonded configurations.
Abstract: Both fullerenes and single-walled carbon nanotubes (SWNTs) exhibit many advantageous properties. Despite the similarities between these two forms of carbon, there have been very few attempts to physically merge them. We have discovered a novel hybrid material that combines fullerenes and SWNTs into a single structure in which the fullerenes are covalently bonded to the outer surface of the SWNTs. These fullerene-functionalized SWNTs, which we have termed NanoBuds, were selectively synthesized in two different one-step continuous methods, during which fullerenes were formed on iron-catalyst particles together with SWNTs during CO disproportionation. The field-emission characteristics of NanoBuds suggest that they may possess advantageous properties compared with single-walled nanotubes or fullerenes alone, or in their non-bonded configurations.

TL;DR: A class of nonlinear PCA (principal component analysis) type learning algorithms is derived by minimizing a general statistical signal representation error and several known algorithms emerge as special cases of these optimization approaches that provide useful information on the properties of the algorithms.
