This paper pursues a formal analogy between natural language dialogue and collaborative real-world action in general. The analogy dependson an analysis of two aspects of collaboration that figure crucially in language use. First, agents must be able to coordinate abstractly about future decisions which cannot be made on present information. Second, when agents finally take such decisions, they ...

The six-degree equations of flight in their classic form do not provide a proper physical perception due to a number of interferences. Nor do they render visible the important role of attack angles. In this study, attempts have been made to develop a complete set of 3D acceleration equations from the equations of normal and tangential acceleration αN=vωv, αt=v ̇. For this purpose, a coordinate s...

Workflow management systems (WfMSs) frequently use data to coordinate the execution of workflow instances. A WfMS evaluates conditions defined on data to make the control flow decisions i.e. selecting the next activity or deciding on an actor. However, data within and outside of a running workflow instance may change dynamically. Modifications of data needed for past control flow decisions may ...

Whether I decide to be a soccer fan, an opera expert or a religious mystic is not a matter I need to coordinate with others; it is the kind of decision that I can take by myself. Think about it and you will find a large number of others decisions that do not require coordination with other people. Indeed, most decisions regarding consumption are best made by the individual doing the consuming. ...

The main purpose of this paper is to study the inventory, production, and contracting decisions of a multi-echelon supply chain with both demand and supply uncertainty. We find that the commonly used wholesale price contracts used by both up-stream and downstream supply-chain members cannot coordinate the system. We then propose a returns policy used by the manufacturer and the retailer, combin...

A coordinate transformation framework for understanding how neurons compute sensorimotor behaviors has generated significant advances toward our understanding of basic brain function. This influential scaffold focuses on neuronal encoding of spatial information represented in different coordinate systems (e.g., eye-centered, hand-centered) and how multiple brain regions partake in transforming ...

There has been a lot of talk about service robots over the past decade, and indeed some service robots are starting to make their way into the real world; delivering food in hospitals, turning book pages for people with physical diabilities, and the like. Unfortunately, while functional, these robots perform their jobs with all the panache of machines. When people want service robots they reall...

This article explores the determinants of public satisfaction (or dissatisfaction) with health and education services in Africa. Among prospective explanations, we consider the users’ poverty, their general perceptions of service accessibility, and their specific experiences with service providers. We find that user-friendliness of services is essential, especially to poorer clients. But daily ...
