How review ambiguity and access costs of SEC review correspondence affect investor judgments
… outcomes from the SEC’s review process) and access costs (i.e., the amount of effort required to access review correspondence)—jointly influence investors’ information processing and their resulting investment judgments. Results show that investors integrate information to a greater extent as …

Design of an Interface to an Information Retrieval Network (Access Costs, Relevance, Bibliographic Databases)
… service centers (SSCs) that make the databases accessible online. Although this has facilitated information searching, the uninitiated user as well as the trained search intermediary are beset with obstacles--disparity in the systems and databases and a dilemma as to the 'proper' choice among …

Cost Optimization Modeling for Airport Capacity Expansion Problems in Metropolitan Areas
… and airport transfer (ORAT) cost, and passenger access cost. These six cost functions can be used to consider a possible trade-off between airport capacity and congestion and address multiple stakeholders’ cost concerns.</p> <p>This deterministic model was validated using an example case of the …

Metrics, fundamental trade-offs and control policies for delay-sensitive applications in volatile environments
… the presence of multiple heterogeneous wireless access methods with different access costs. Our objective is to analytically characterize the trade-off between usage cost and QoE metrics. We model each access network as a server that provides packets to the user according to a Poisson process …

Transit network design for areas with low and/or heterogeneous demand
… transit agencies to provide sparser and less accessible service so as to stay economical, which however further deteriorates passenger experience and deters patronage. Spatially heterogeneous demand as well as city street characteristics (e.g., network layout) calls for variation in transit …
