As Solow once remarked to me, we would not now be concerned with the question [the existence of the aggregate production function] had Paul Douglas found labor's share of American output to be twenty-five per cent and capital's share seventy-five instead of the other way around [Fisher, 1969, 572]. I hope that someone skilled in econometrics and labor will audit and evaluate my critical finding...

Roughly twenty five years ago Hofer asked: can the cylinder B2(1)×R2(n−1) be symplectically embedded into B2(n−1)(R)×R2 for some R > 0? We show that this is the case if R > √ 2n−1 + 2n−2 − 2. We deduce that there are no intermediate capacities, between 1-capacities, first constructed by Gromov in 1985, and n-capacities, answering another question of Hofer. In 2008, Guth reached the same conclus...

PURPOSE To determine the retention of knowledge along the years after certification of physicians as ophthalmology specialists.

This research report summarises the results of an exploratory teaching program in a primary and secondary school in rural New South Wales, Australia, focused on improving basic mathematics skills. Pupils, aged 11 to 13 years, identified as consistently low-achieving in Mathematics were targeted. The program ran for approximately twenty-five weeks with pairs of pupils involved in five thirty-min...

The potential importance of congestion effects on the management and rationing of recreational facilities and services in the presence of heterogeneous preferences were highlighted nearly twenty-five years ago by Freeman and Haveman (1977). While there have been a number of theoretical models extending and expanding upon this work (McConnell 1988; Anderson 1993), empirical research evaluating s...

The exponentially increasing body of work on the human brain has not only taught us a lot about how the brain does cognition, it has also had a profound influence on other disciplines that study cognition and behaviour. A notable example, interestingly enough, is philosophy. A small movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods...

Superior early numerical competencies of children in several Asian countries have (amongst others) been attributed to the higher transparency of their number word systems. Here, we directly investigated this claim by evaluating whether Japanese children's transcoding performance when writing numbers to dictation (e.g., "twenty five" → 25) was less error prone than that of German-speaking childr...

OBJECTIVES This paper will provide a history of how family-driven care has evolved in the United States. METHODS Several examples of family-driven care including the National Policy Academy led by the Federation of Families for Children's Mental Health, the Jefferson County Kentucky's Parent Advocacy Program, and the Family Ties Resource Centers in Westchester, New York, and the 2009 American...

During the year 1911-12 the author gave to forty classes in New York City ten-minute tests in the fundamental operations in arithmetic at four different periods of a two-session school day. The results were compared as to quantity and quality in order to suggest the relative efficiency at those periods.1 In February and March, 1913, twenty-five-minute tests in the fundamental operations were gi...
