This textbook  describes in detail the best and most current methods to care for patients in the emergency department, including initial evaluation, generation of differential diagnoses, problem solving, and management of challenging conditions based on presenting symptoms.

One of the most common phenomena of language use among bilingual speakers is language alternation. Yet, from a theoretical perspective, it is impossible in principle both grammatically and socio-functionally. Therefore, a crucial question is how to account for its actual possibility despite this theoretical impossibility. Drawing on Ethnomethodology, this problem is described as that of order in talk in two languages. The book offers a critical reading of current approaches to language alternation as accounts of this essential problem of order.

The International Mathematical Olympiad competition is held every year with the final taking place in a different country. The final consists of a two day exam with the contestants being challenged to solve three difficult problems each day. This book contains the questions from the finals taking place between 1986 and 1999 inclusive. For each problem the author has included at least one solution and often remarks about alternative approaches and the significance of the problem. Many of the solutions are derived from answers given by contestants rather than the organisers as these were often the most elegant solutions. This collection will be of great value to students preparing for the IMO and to all others who are interested in problem solving in mathematics.

 
A brief narrative description of the journal article, document, or resource.
This book contains about 200 problems. It is suggested that it be used by students, teachers or anyone interested in exploring mathematics. In addition to a general discussion on problem solving, there are problems concerned with number theory, algebra, geometry, and combinatorics.
