    • A brief history of research synthesis. 

      Chalmers, Iain; Hedges, Larry V; Cooper, Harris (Eval Health Prof, 2002-03)
      Science is supposed to be cumulative, but scientists only rarely cumulate evidence scientifically. This means that users of research evidence have to cope with a plethora of reports of individual studies with no systematic ...
    • A tale of two callings. 

      Lefkowitz, Robert J (J Clin Invest, 2011-10)
    • Carrots and sticks: fertility effects of China's population policies. 

      McElroy, M; Yang, DT
      For 20 years following 1949, average total fertility per woman in China hovered just above six children. The year 1970 marked the beginning of persistent fertility declines. By 1980, the rate had dropped to 2.75, and since ...
    • Enhancing the Hodgkin-Huxley Equations: Simulations Based on the First Publication in the Biophysical Journal. 

      Moore, John W (Biophys J, 2015-10-06)
      The experiments in the Cole and Moore article in the first issue of the Biophysical Journal provided the first independent experimental confirmation of the Hodgkin-Huxley (HH) equations. A log-log plot of the K current versus ...
    • Global nitrogen budgets in cereals: A 50-year assessment for maize, rice, and wheat production systems. 

      Ladha, JK; Tirol-Padre, A; Reddy, CK; Cassman, KG; Verma, Sudhir; Powlson, DS; van Kessel, C; ... (10 authors) (Scientific reports, 2016-01-18)
      Industrially produced N-fertilizer is essential to the production of cereals that supports current and projected human populations. We constructed a top-down global N budget for maize, rice, and wheat for a 50-year period ...
    • 'One physical system': Tansley's ecosystem as Earth's critical zone. 

      Richter, Daniel deB; Billings, Sharon A (The New phytologist, 2015-05)
      Integrative concepts of the biosphere, ecosystem, biogeocenosis and, recently, Earth's critical zone embrace scientific disciplines that link matter, energy and organisms in a systems-level understanding of our remarkable ...
    • Steep increase in best-practice cohort life expectancy. 

      Shkolnikov, Vladimir M; Jdanov, Dmitri A; Andreev, Evgeny M; Vaupel, James W (Popul Dev Rev, 2011)
      We analyze trends in best-practice life expectancy among female cohorts born from 1870 to 1950. Cohorts experience declining rather than constant death rates, and cohort life expectancy usually exceeds period life expectancy. ...
    • The annual ASCI meeting: does nostalgia have a future? 

      Lefkowitz, Robert J (J Clin Invest, 2008-04)
      For many academic physician-scientists, the yearly Tri-Societies meeting of the ASCI, AAP, and AFCR during the 1960s, '70s, and '80s was an annual rite of spring and the focal point of the academic year. In this brief essay, ...
