Off Policy Reinforcement Learning for Real-World Settings
(2021-07-12)In this dissertation, we aim to adapt reinforcement learning (RL) to real-world, high-risk settings. We study how to optimize sequential decision-making in complex settings with large observational data repositories where ... -
Off-axis symbiosis found: characterization and biogeography of bacterial symbionts of Bathymodiolus mussels from Lost City hydrothermal vents
(Wiley-Blackwell, 2006)Organisms at hydrothermal vents inhabit discontinuous chemical ‘islands’ along mid-ocean ridges, a scenario that may promote genetic divergence among populations. The 2003 discovery of mussels at the Lost City Hydrothermal ... -
Off-fault Damage Patterns Due to Supershear Ruptures with Application to the 2001 Mw 8.1 Kokoxili (Kunlun) Tibet Earthquake
(American Geophysical Union, 2007)We extend a model of a two-dimensional self-healing slip pulse, propagating dynamically in steady state with slip-weakening failure criterion, to the supershear regime in order to study the off-fault stressing induced by ... -
Off-fault Plasticity and Earthquake Rupture Dynamics: 1. Dry Materials or Neglect of Fluid Pressure Changes
(American Geophysical Union, 2008)We analyze inelastic off-fault response during earthquakes. Spontaneous crack-like rupture, with slip weakening, is modeled in 2-D plane strain using an explicit dynamic finite element procedure. A Mohr-Coulomb type ... -
Off-Fault Plasticity and Earthquake Rupture Dynamics: 2. Effects of Fluid Saturation
(American Geophysical Union, 2008)We present an analysis of inelastic off-fault response in fluid-saturated material during earthquake shear rupture. The analysis is conducted for 2-D plane strain deformation using an explicit dynamic finite element ... -
The Off-Label Use of Acepromazine Maleate
(2006)In this paper, I offer an evaluation of the off-label use of Acepromazine Maleate by foxhunters. In Chapter One, I provide readers with an explanation of the most important elements of the topic, including what Acepromazine ... -
Off-Label Use of Prescription Drugs should be Regulated by the FDA
(2003)The FDA does not subject all uses of drugs to a rigorous approval process. There are many justifications given for this. I lay out a system that divides drug-indication sets into four categories: (1) FDA approved; (2) ... -
OFF-LABEL USES OF APPROVED DRUGS A New Compromise is Needed
(1995)Washington, D.C. is teeming with speculation regarding the likely effects of a new political scenery and the Republican Contract With America. As the new Congress is taking form and adjusting to a new reality, one voice ... -
Off-patent drugs at brand-name prices: a puzzle for policymakers
(Oxford University Press, 2016)In August 2015, Turing Pharmaceuticals acquired the marketing rights to Daraprim (pyrimethamine), a drug used to treat parasitic infections like malaria and toxoplasmosis. Soon after, Turing caused an uproar when it announced ... -
Off-Policy Evaluation of Reinforcement Learning in Healthcare
(2020-08-10)Reinforcement learning is a method for learning optimal strategies for tasks which require making sequences of decisions. The ability to make decisions in a manner which balances short versus long term outcomes makes ... -
The Office of Combination Products: Its Roots, Its Creation, and Its Role
(2005)The Office of Combination Products (OCP), within the Food and Drug Administration (FDA), was created formally by statute in December, 2002. Upon its creation, the Office became broadly responsible for overseeing the ... -
Officers and Council Members of the British Society for the History of Science, 1947–97
(Cambridge University Press, 1997)As described elsewhere in this issue of BJHS, preliminary steps towards founding a society for the history of science in Britain were taken in 1946. A meeting was held at the Science Museum, London, on 22 November 1946, ... -
Official Development Assistance (ODA): Are There Correlations Between ODA and Corruption in Sub-Saharan Africa?
(2023-06-21)Abstract Taking a broad-brush view of the past 60 years of official development assistance (ODA) in Sub-Saharan Africa (SSA), leading to a decision that ODA is a total failure for all SSA countries, is both misleading and ... -

Offline eLearning for undergraduates in health professions: A systematic review of the impact on knowledge, skills, attitudes and satisfaction
(Edinburgh University Global Health Society, 2014)Background: The world is short of 7.2 million health–care workers and this figure is growing. The shortage of teachers is even greater, which limits traditional education modes. eLearning may help overcome this training ... -
The Offset and Host Light Distributions of Long Gamma-Ray Bursts: A New View From Hst Observations of Swift Bursts
(American Astronomical Society, 2016)We present the results of an extensive Hubble Space Telescope (HST) imaging study of ∼100 Swift longduration gamma-ray bursts (LGRBs) spanning 0.03 . z . 9.4 using relative astrometry from ground- and space-based afterglow ... -
Offshore Investment Funds: Monsters in Emerging Markets?
(Center for International Development at Harvard University, 2001-06)The 1997-98 financial crises in the emerging markets have brought to the foreground the concern about offshore investment funds and their possible role in exacerbating financial market volatility. Offshore investment funds ... -
Offshore Wind in the Eastern United States
(Belfer Center for Science and International Affairs, 2021-12)In the last decade, many states set ambitious goals to decarbonize their energy portfolios. Seven states along the Atlantic coast are pursuing 100% clean electricity targets, while others have adopted stringent emissions ... -
Offshoring and the Role of Trade Agreements
(National Bureau of Economic Research, 2008)The rise of offshoring of intermediate inputs raises important questions for commercial policy. Do the distinguishing features of offshoring introduce novel reasons for trade policy intervention? Does offshoring create new ... -
Offshoring in a Knowledge Economy
(MIT Press, 2006)How does the formation of cross-country teams affect the organization of work and the structure of wages? To study this question, we propose a theory of the assignment of heterogeneous agents into hierarchical teams, where ...
