    • Professional Disequilibrium: Conflict of Interest in Economics 

      Thompson, Dennis (Oxford University Press, 2014-03-03)
      <p>The economics profession lags behind others in adopting policies to regulate conflict of interest. The purposes of conflict of interest regulations, which are often misunderstood, are to minimize bias in research and ...
    • Profile-Based Optimization with Statistical Profiles 

      Gloy, Nick; Wang, Zheng; Zhang, Catherine; Chen, Brad; Smith, Michael J. (1997)
      An important barrier to the use of profile-based optimization is the generation of high-quality profile data. In this paper we describe our experience with a prototype system for continuous and automatic generation of ...

    • Profiles of Everyday Thought Suppression 

      Ie, Amanda Yen Lin (2014-06-06)
      The present research assessed whether levels of depression, anxiety and worry, obsessive-compulsive distress, and psychopathy were differentially related to distinct thought suppression profiles. As a means to achieving ...
    • Profiling and Improving the Specificity of Site-Specific Nucleases 

      Guilinger, John Paul (2014-06-06)
      Programmable site-specific endonucleases are useful tools for genome editing and may lead to novel therapeutics to treat genetic diseases. TALENs can be designed to cleave chosen DNA sequences. To better understand TALEN ...
    • Profiling originalism 

      Greene, Jamal; Ansolabehere, Stephen Daniel; Persily, Nathaniel (Columbia Law Review Association, Inc., 2011)
      Originalism is a subject of both legal and political discourse, invoked not just in law review scholarship but also in popular media and public discussion. This Essay presents the first empirical study of public attitudes ...
    • Progenitor Cell Diversity and Function in the Developing Cerebral Cortex 

      Wang, Peter Pei (2015-05-07)
      The human cerebral cortex, the largest structure of our brain, is the seat of our most highly developed cognitive functions. Its normal development, proper function, and ultimate size depend on a precisely controlled balance ...
    • Prognostic Factors in Advanced Cancer Patients: Evidence-Based Clinical Recommendations—A Study by the Steering Committee of the European Association for Palliative Care 

      Maltoni, Marco; Caraceni, Augusto; Brunelli, Cinzia; Broeckaert, Bert; Christakis, Nicholas; Eychmueller, Steffen; Glare, Paul; Nabal, Maria; Viganò, Antonio; Larkin, Philip; De Conno, Franco; Hanks, Geoffrey; Kaasa, Stein (American Society of Clinical Oncology (ASCO), 2005)
      Purpose To offer evidence-based clinical recommendations concerning prognosis in advanced cancer patients. Methods A Working Group of the Research Network of the European Association for Palliative Care identified ...
    • A prognostic model of the sea-ice floe size and thickness distribution 

      Horvat, Christopher Harold; Tziperman, Eli (Copernicus GmbH, 2015)
      Sea ice exhibits considerable seasonal and longer-term variations in extent, concentration, thickness, and age, and is characterized by a complex and continuously changing distribution of floe sizes and thicknesses, ...
    • Prognostication and Bioethics 

      Christakis, N (Massachusetts Institute of Technology Press (MIT Press), 1999)
    • The Program of Gene Transcription for a Single Differentiating Cell Type During Sporulation in Bacillus Subtilis 

      Rudner, David Z; Liu, Jun; Ferguson, Caitlin; Conlon, Erin M; Losick, Richard; Wang, Stephanie T; Sato, Tsutomu; Haga, Koki; Eichenberger, Patrick; Fujita, Masaya; Jensen, Shane T (Public Library of Science, 2004)
      Asymmetric division during sporulation by Bacillus subtilis generates a mother cell that undergoes a 5-h program of differentiation. The program is governed by a hierarchical cascade consisting of the transcription factors: ...
    • Programed Death is Favored by Natural Selection in Spatial Systems 

      Werfel, Justin; Ingber, Donald E.; Bar-Yam, Yaneer (American Physical Society, 2015)
      Standard evolutionary theories of aging and mortality, implicitly based on mean-field assumptions, hold that programed mortality is untenable, as it opposes direct individual benefit. We show that in spatial models with ...
    • Programmable biofilm-based materials from engineered curli nanofibres 

      Nguyen, Peter Q; Botyanszki, Zsofia; Tay, Pei Kun Richie; Joshi, Neel S. (Nature Publishing Group, 2014)
