The pricing of telecommunications services and products is undergoing unprecedented change in many countries throughout the world -as a consequence of radical and rapid changes in the organization of the industry. These, in turn, have flowed from technological developments, shifts in the regulatory/government climate, and/or judicial decisions, all of which have altered the economic fundamental...

There is a class of joke which consists of an anecdote, which is sometimes quite long and often has no inherently humorous content, followed by a ®nal line which is a distorted form of some well-known phrase, proverb or quotation. Usually this ®nal line purports to summarize or draw a moral from the preceding story. This genre has some unusual aspects, from the viewpoint of conventional claims ...

It is more than usually fitting that a general summary of medicine of this kind should appear under the editorship of one who has spent so many years in the active acquisition of a very wide experience, and who now has a comparative degree of leisure for other work with more than an average degree of ability to present the results of his experience in an eminently attractive form. The introduct...

This is an eprint approximation to [Thu86], which is the definitive form of this paper. This eprint is provided for convenience only; the theorem numbering of this version is different, and not all corrections are present, so any reference or quotation should refer to the published form. Parts II and III ( [Thua] and [Thub]) of this series, although accepted for publication, for many years have...

Kecently we have had opportunity in the Psychological Clinic to observe five cases which were referred for examination because of school retardation following a history of chorea, or of what is more commonly known as St. Vitus' Dance. It has been estimated that the common type of chorea comprises twenty per cent of the nervous disorders of children, and that, from one investigation reported by ...

Deploying and evaluating a new technology is a major challenge in ICTD research. Introducing new technologies can be hampered by a lack of cultural insight, poor or delayed feedback, and limited evaluation procedures, among other factors. This short paper offers a model for introducing technology in developing regions that mitigates these factors. We call these steps the “Huzzah method,” inspir...

Others have cited Sophocles’ quote from 400 B.C., “One must learn by doing the thing, for though you think you know it-you have no certainty, until you try.” Or, one could quote George Santayana, “The great difficulty of education is to get experience out of ideas.” It is hard to argue that experience will not lead to learning under the right conditions. However, it will be argued that the resu...

If we discard the assumption that politicians and public sector bureaucrats are somehow motivated to maximize a social welfare function, as the most superficial observation of the world entreats us to do, the most important reason for decentralizing the public sector is that decentralization makes possible and, in effect, stimulates intergovernmental competition. Indeed, once it is accepted tha...

Wemodel semantic interpretation operationally : constituents interact as their combination in discourse evolves from state to state. The states are recursive data structures and evolve from step to step by context-sensitive rewriting. These notions of context and order let us explain inverse-scope quantifiers and their polarity sensitivity as metalinguistic quotation of the wider scope.

In this paper, a simultaneous lead time quotation and lot sizing problem in an assembly system is investigated. We address a production system with a product that has deterministic demand over a T-period planning horizon and is produced in lots because of the economy of scale. If a lot is completed before the demand period, inventory carrying cost is incurred. On shortages, a lead time is quote...
