The business travel industry is characterised by triadic relationships that are currently undergoing dramatic changes. In a business travel distribution context, the triad consists of the company buying business travel services, an intermediary, and the service supplier. Traditionally, airlines have used business travel agencies as an intermediary and distribution channel for selling the flight...

Abstract This paper studies how punishment affects future compliance behavior and isolates deterrence effects mediated by learning. Using administrative data from speed cameras that capture the full driving histories of more than a million cars over several years, we evaluate responses to at extensive (receiving speeding ticket) intensive margins (tickets with higher fines). Two complementary e...

Miyaji et.al proposed a fully functional(i.e., satisfying unforgeability, exculpability,anonymity, traceability, unlinkability, and revocability.) group signature over only known-order groups, that is based only on Discrete logarithm related assumptions, specifically, multiple DLP they proposed in the same paper [MU04]. In this paper, we point out their scheme and an improved scheme [ZZW05] do ...

The paper provides a complete description of the digital signature scheme based on Stern identification protocol. We also present proof existential unforgeability under chosen message attack (EUF-CMA) in random oracle model (ROM). Finally, we discuss choice parameters, particular providing 70-bit security.

Computational puzzles are mildly difficult computational problems that require resources (processor cycles, memory, or both) to solve. Puzzles have found a variety of uses in security. In this paper we are concerned with client puzzles: a type of puzzle used as a defense against Denial of Service (DoS) attacks. Before engaging in a resource consuming protocol with a client, a server demands tha...

In the paper a method of translation applied in a new system TGT is discussed. TGT translates texts written in Polish into corresponding utterances in the Polish sign language. Discussion is focused on text-into-text translation phase. Proper translation is done on the level of a predicative representation of the sentence. The representation is built on the basis of syntactic graph that depicts...

Clinical response to bypassing agents (BPAs) may vary between patients. Surgery is a particular situation, requiring effective hemostasis during the procedure and for several days postoperatively to obtain satisfactory wound healing. However, the optimal dose of BPA in different surgical situations has not been clearly established. We report here a prospective assessment of thrombin generation ...

People are reluctant to exchange lottery tickets, a result that previous investigators have attributed to anticipated regret. The authors suggest that people's subjective likelihood judgments also make them disinclined to switch. Four studies examined likelihood judgments with respect to exchanged and retained lottery tickets and found that (a) exchanged tickets are judged more likely to win a ...
