Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries must invest in air transportation infrastructure to ensure their ability to meet current and future demand for aviation services. The objective of this paper is to develop and illustrate a methodology for evaluating the strategic value of air transportation infrastructure, in particular the benefits associated with the ability to react quickly to changes in the market. The hypothesis is that by recognizing and taking advantage of this strategic value, it may be possible to design better policies for aviation infrastructure delivery.The methodology developed here uses system dynamics to model different strategies for infrastructure delivery. These strategies are defined by three variables: the amount of capacity increase, the time to deliver the capacity and the congestion threshold that triggers the need for capacity delivery. Monte Carlo simulation is used to take into account multiple sources of uncertainty. The model shows that a strategy of capacity delivery based on small increments and short response times can yield more benefits than strategies that consider large capacity increases and long response times. Furthermore, in the specific airport example considered here, it was found that a congestion threshold of 75% should be the trigger for capacity enlargements if strategies based on small capacity increments and 1 or 5 years to increase capacity are considered. The lesson for decision-makers is that congestion delays must be addressed with foresight. 相似文献

Supervisor's human resources (HR) decisions have a significant impact on the employees they manage but have been found to be subject to bias. The upward influence tactics use by subordinates can play a role in this. We investigated the effects of seven upward influence tactics on supervisor job‐performance ratings and the extent of subordinate flexible working arrangements (FWAs). Supervisors are often responsible for determining whether employees are granted FWAs. We posit an alternative theoretical mechanism by which upward influence tactics bring about their effects, mediated through two distinct types of respect, mutual appraisal respect and mutual recognition respect. We collected data from 389 matched supervisor–subordinate dyads, and found that both mutual appraisal respect and mutual recognition respect mediated relationships between several upward influence tactics and both job‐performance ratings and FWAs. Our findings show that upward influence tactics affect the quality of the relationship between employees and their supervisors, specifically, these two forms of mutual respect. Further, both mutual appraisal respect and mutual recognition respect may explain why supervisors show favoritism to some subordinates over others, in reaching HR decisions in these areas. 相似文献

This paper examines the Next Steps development from both contemporaneous and historical perspectives. Specifically, it traces the reliance on a distinct model of management and accounting in Next Steps (1988) and its predecessors (FMI, 1982; and Fulton, 1968). This shows not only that there are a series of commonalities within the details of these various reforms of central government, over the past three decades, but also that these various reforms share foundations which are embedded in 'management thought' on best practice in the 1950s and 1960s. We identify contemporaneous studies in both management and management accounting which could have informed these reforms, and make suggestions for situationally specific means of improving management and accounting in central government. 相似文献

The purpose of this research reflection is to set the stage for a more detailed research agenda in exploring event sport tourism experiences of support partners (SPs) during events. Using photo elicitation, the article presents a preliminary empirical case study. Visual materials were assembled by three female participants to interrogate how SPs experience “spectator space” and explore the processes that produced those experiences, an area of study that remains relatively unexplored in leisure research. Initial findings show how waiting to see the triathlete can be anxiety-provoking, but the release of emotion when smiles are exchanged constitutes core activities of being there. However, there are more questions than answers, and there is a need for further inquiry. Suggestions for future research on the impact of serious leisure on intimate others are given. 相似文献
