A CARDINAL GOAL of librarians of institutions of higher learning is to build up collections of permanent value. For a non-fiction work to serve this purpose, we would expect it to be read in whole or in part and to be referred to for such things as facts, opinions, ideas, or felicitous phrasing. College librarians have to buy books selectively, a task made more difficult by the rising cost of b...

Perhaps more than any other film practices, cinematic adaptations have drawn the attention, scorn, and admiration of movie viewers, historians, and scholars since 1895. Indeed, even before this origin of the movies with the first public projections of films by Auguste and Louis Lumière in France and Max and Emil Skladanowsky in Germany critical voices worried about how photography had already e...

Recent observations of biologically generated turbulence in the ocean have led to conflicting conclusions regarding the significance of the contribution of animal swimming to ocean mixing. Measurements indicate elevated turbulent dissipation—comparable with levels caused by winds and tides—in the vicinity of large populations of planktonic animals swimming together 1. However, it has also been ...

This essay discusses Peirce’s appeal to logical machines as an argument against psychologism. It also contends that some of Peirce’s anti-psychologistic remarks on logic contain interesting premonitions arising from his perception of the asymmetry of proof complexity in monadic and relational logical calculi that were only given full formulation and explication in the early twentieth century th...

Technical problems, incomprehensible interfaces, and insufficient search engines are part of that problem. With the interplay and adjustment of several advanced, preference driven middleware components we achieve to automate skills tha...

We estimate flight-level price elasticities using a database of online prices and seat map displays. In contrast to market-level and route-level elasticities reported in the literature, flight-level elasticities can forecast responses in demand due to day-to-day price fluctuations. Knowing how elasticities vary by flight and booking characteristics and in response to competitors’ pricing action...

As a teenager in a South Dakota hamlet (Pierpont, population 326 in the 1940 census) I had no idea that I would become a scientist. The only formal science course my tiny high school (40 students in four grades, taught by three teachers) offered was physics, taught by the sports coach (a history major) and featuring the ‘‘dissection’’ of a 1928 Overland (teacher: ‘‘I have been told that the mod...
