It is shown that uncertainty relations, as well as coherent and squeezed states, are structural properties of stochastic processes with Fokker-Planck dynamics. The quantum mechanical coherent and squeezed states are explicitly constructed via Nelson stochastic quantization. The method is applied to derive new minimum uncertainty states in time-dependent oscillator potentials. Electronic Mail: d...

A database management system provides the ideal support for electronic mail applications. The Walnut mail system built at the Xerox Palo Alto Research Center was recently redesigned to take better advantage of its underlying database facilities. The ability to pose ad-hoc queries with a “fill-in-the-form” browser allows people to browse their mail quickly and effectively, while database access ...

This article considers the nature of e-mail from the recipient’s perspective—what the seeminglyfreeandeasycommunicationreallycosts therecipient. Informationgathered by electronic monitoring software is shown to be at odds with the results of an online survey of e-mail users’ perceptions of their e-mail experience—users drastically underestimate the disruptive effects of e-mail. The conclusion i...

today, many companies have multiple channels, such as sales force, direct mail / catalog, internet and broadcast channels, telephone, etc. for providing goods and services to its customers. multiple distribution channels, despite having benefits, several challenges such as the incidence of conflict, allocation of product, free ride some members have being emerged. the aim of this study was to i...

How and why people choose which communication medium to use is an important issue for both behavioral researchers and software product developers. Little is yet known about how and why people in organizations choose among new media like electronic mail and voice mail, although the availability and use of new media are increasing dramatically. Media richness theory (MRT) is the most prominent, i...
