How do Chinese firms deal with inter-organizational conflict?

Based on social exchange and customer relationship marketing theory, this study examines how ethical leadership contributes to inter-organizational conflict management (task conflict (TC) and relationship conflict), and the moderating role of task interdependence in these relationships. Data was collected from 81 suppliers and 45 corresponding managers of a large group company in China. Results show that ethical leadership is negatively associated with the levels of inter-organizational conflict,whether task or relationship. Task interdependence significantly moderates the relationship between ethical leadership and TC. Managerial implication in terms of creating sound buyer–supplier relationship through an ethical perspective is discussed.

Horses in the countryside: conflict or cooperation?

Recognising the growing significance of sport and recreation in the countryside, this paper seeks to examine the changing demand for, and supply of, opportunities for horse riding in the countryside. It considers the physical problems associated with horse riding, together with the changing social context. The paper considers possible solutions to the issues raised, both within existing rights of way legislation and via new opportunities created by the revisions to agricultural support that have occurred in the last decade. The paper concludes that while the new opportunities have ameliorated some of the problems associated with the supply of land for horse riding, no new rights of access have been conferred. The ability of horse riders to guarantee continued provision will be governed partially by the market but also by future agricultural support policy.

Cognitive process modelling of controllers in en route air traffic control

In recent years, various efforts have been made in air traffic control (ATC) to maintain traffic safety and efficiency in the face of increasing air traffic demands. ATC is a complex process that depends to a large degree on human capabilities, and so understanding how controllers carry out their tasks is an important issue in the design and development of ATC systems. In particular, the human factor is considered to be a serious problem in ATC safety and has been identified as a causal factor in both major and minor incidents. There is, therefore, a need to analyse the mechanisms by which errors occur due to complex factors and to develop systems that can deal with these errors. From the cognitive process perspective, it is essential that system developers have an understanding of the more complex working processes that involve the cooperative work of multiple controllers. Distributed cognition is a methodological framework for analysing cognitive processes that span multiple actors mediated by technology. In this research, we attempt to analyse and model interactions that take place in en route ATC systems based on distributed cognition. We examine the functional problems in an ATC system from a human factors perspective, and conclude by identifying certain measures by which to address these problems. This research focuses on the analysis of air traffic controllers' tasks for en route ATC and modelling controllers' cognitive processes.

Allosteric mechanism controls traffic in the chaperone/usher pathway

Many virulence organelles of Gram-negative bacterial pathogens are assembled via the chaperone/ usher pathway. The chaperone transports organelle subunits across the periplasm to the outer membrane usher, where they are released and incorporated into growing fibers. Here, we elucidate the mechanism of the usher-targeting step in assembly of the Yersinia pestis F1 capsule at the atomic level. The usher interacts almost exclusively with the chaperone in the chaperone:subunit complex. In free chaperone, a pair of conserved proline residues at the beginning of the subunit-binding loop form a ‘‘proline lock’’ that occludes the usher-binding surface and blocks usher binding. Binding of the subunit to the chaperone rotates the proline lock away from the usher-binding surface, allowing the chaperone-subunit complex to bind to the usher. We show that the proline lock exists in other chaperone/usher systems and represents a general allosteric mechanism for selective targeting of chaperone:subunit complexes to the usher and for release and recycling of the free chaperone.
