A principal acquires information about a shock and then discloses it to an agent. After the disclosure, the principal and agent each decide whether to take costly preparatory actions that yield mutual benefits but only when the shock strikes. The principal maximizes his expected payoff by controlling the quality of his information, and the disclosure rule. We show that even when the acquisition...

Smartwatches collect a broad range of physical activity data during usage. We postulate that Perceived Privacy Risk has a direct negative influence on the Behavioral Intention to Use smartwatches and an indirect negative influence on the Behavioral Intention to Use them through Perceived Usefulness and Perceived Enjoyment. After collecting 229 online questionnaires and applying a SEM approach, ...

With rising trading volumes in domestic and cross-border security transactions, risks faced by global financial firms and markets are increasing. To manage settlement risks and maintain competitiveness in global financial markets, the U.S. Security and Exchange Commission (SEC) has decided to shorten the settlement cycle of security transactions from the current T+3 to T+1. As a result, key pla...

This paper asserts that economists of the mid twentieth century developed two methods of analyzing institutions. Austrian and Coasean economists developed complementary approaches to institutional analysis. Coase developed a research program of Comparative Institutional Analysis, whereby economists compare alternative institutions according to their most similar features. Ludwig von Mises and F...

Education and training interventions can be evaluated through the success of learning outcomes. Kirkpatrick's four-level model is a widely accepted and highly popular evaluation tool. However, some criticise the model's shortcomings. This article will examine the extent to which the four-level model can evaluate design and technology students' learning about aesthetics after an intervention by ...

Our objective was to enable an end-user to create complex queries to drug information sources through functional composition, by creating sequences of functions from application program interfaces (API) to drug terminologies. The development of a functional composition model seeks to link functions from two distinct APIs. An ontology was developed using Protégé to model the functions of the RxN...

Ontologies serve as a mean to establish a conceptually concise basis for communicating knowledge for many purposes. Within the information integration area, ontologies are useful to solve heterogeneity problems. They provide a set of knowledge terms, including the vocabulary, the semantic interconnections and some simple rules of inference and logic. In this paper we present a helpful method to...

Since its launch on October 2002 the INTEGRAL satellite is performing an deep survey of the hard X–ray sky with unprecedented sensitivity and positional accuracy. This allowed pinpointing, through positional cross-correlation with catalogs at longer wavelengths, possible optical/near-infrared candidates for the hard X–ray sources of still unknown nature. In this presentation I will describe thi...

We consider the problem of data sharing between autonomous data sources in an environment where constraints cannot be placed on the shared contents of sources. Our solutions rely on the use of mapping tables which define how data from different sources are associated. In this setting, the answer to a local query, that is, a query posed against the schema of a single source, is augmented by retr...
