OBJECTIVE To compare the sensitivity of 3 different criteria-von Reyn, Duke, and modified Duke-in diagnosing infective endocarditis (IE) in children. STUDY DESIGN Retrospective case study in a tertiary pediatric hospital. METHODS AND RESULTS Between 1985 and 2001, 41 episodes of IE were documented in 40 children (median: 7 years old; range: 1 week to 18 years). The diagnosis was based on ec...

Health care in the United States faces an uncertain future with the rising costs of care, the growth of the aging population, the chronic health conditions associated with the aging, and a predicted shortage in the physician workforce, among other issues. Health care costs are rising at an annual rate of 13% to 15%; health insurance premiums continue to rise at an incredible rate as well. The n...

The aim of this chapter is ambitious though, on the surface, straightforward. It is to convey a sense of educational research as twin-focused — a systematic inquiry that is both a distinctive way of thinking about educational phenomena, that is, an attitude, and of investigating them, that is, an action or activity. Others have dubbed this as ‘a mode of interrogation for education’ (Brown and D...

Machine-readable versions of everyday dictionaries have been seen as a likely source of information for use in natural language processing because they contain an enormous amount of lexical and semantic knowledge. However, after 15 years of research, the results appear to be disappointing. No comprehensive evaluation of machine-readable dictionaries (MRDs) as a knowledge source has been made to...

In Cameroon, sustainable timber management relies on the model of large logging concession. However, over the past fifteen years, small-scale logging has become a common activity, with two different forms. First, the creation of community forests in the late 1990s allowed village associations to legally harvest, process and trade timber, almost always with the support of external actors such as...

In this paper we introduce a new coalitional value in the context of TU games with an a priori system of unions, which it is called the symmetric coalitional Banzhaf value. This value satisfies the property of symmetry in the quotient game, the quotient game property, and it is a coalitional value of Banzhaf. Several characterizations are provided and two political examples illustrate the diffe...

This paper proposes an extension of the Identity model developed by Akerlof and Kranton (2000) that incorporates a beliefs dimension based on the consumption of information. The model is then applied to the process by which consumer-voters consume campaign media and selectively accept information to vote. Based on the assumption that political parties act to maximize their stream of future cont...
