The proposed model, by incorporating both 1) banker screening of new issues and 2) costly evaluation by investors, is the first to admit endogenous double-sided information production. It demonstrates a nontrivial link between these two sides: the banker wishes to structure a sale conducive to investor research because selling to an uninformed pool would result in his own shirking. One applicat...

We conducted a survey of over 5,000 telephone users who were customers of one large cellular telephone company covering four major geographical areas. Our primary goal was to assess the utility of ascertaining information on telephone use and type from telephone company records. We compared information from 3,949 respondents with corresponding data from company billing records. We found that 48...

As it stands the Internet’s “one size fits all” approach to information retrieval presents the average user with a serious information overload problem. Adaptive hypermedia systems can provide a solution to this problem by learning about the implicit and explicit preferences of individual users and using this information to personalise information retrieval processes. We describe and evaluate a...

More than half of Chinese Internet users participate in Weibo, the most popular social media and microblogging platform in China. Weibo encourages members to voluntarily contribute personal information, leading to potential privacy invasion. This study examines how trust in other members and perceptions of government intrusion affect privacy-related attitude and behavior on this social platform...

As network capacities increase, wide-area distributed parallel computing may become feasible. This paper addresses one of the issues involved in using an asynchronous transfer mode (ATM) network for such a purpose|that of developing an appropriate call admission control (CAC) procedure for such applications given the special nature of their traac. In this proposal, connections belonging to the ...

The ability to discriminate and distinguish among individual documents in the ever-increasing volume of information available through digital networks is becoming more and more difficult. With websites being added to the 100 million installed base by tens of thousands per month, information overload is inevitable (H. Berghel, 1997). There are two basic paradigms for dealing with this informatio...

This paper studies international equity markets when some investors have private information that is valuable for trading in many countries simultaneously. We use a dynamic model of equity trading to show that global private information helps explain US investors’ trading behavior and performance. In particular, the model predicts global return chasing (positive co-movement of US investors’ net...

A receiver wants to compute a function f of two correlated sources X and Y and side information Z. What is the minimum number of bits that needs to be communicated by each transmitter? In this paper, we derive inner and outer bounds to the rate region of this problem which coincide in the cases where f is partially invertible and where the sources are independent given the side information. Fro...

Source coding with correlated decoder side information is considered. We impose the practical constraint that the encoder be unaware of even the statistical dependencies between source and side information. Two classes of rate-adaptive distributed source codes, both based on Low-Density Parity-Check (LDPC) codes, are developed and their design is studied. Specific realizations are shown to be b...
