TL;DR: In this paper, a set of guidelines for annotating time expressions with a canonicalized representation of the times they refer to, and methods for extracting such time expressions from multiple languages are described.

TL;DR: Monte Carlo simulations show that data collection heuristics based on p values lead to biases in estimated effect sizes and Bayes factors and to increases in both false-positive and false-negative rates, depending on the specific heuristic.
Abstract: The ongoing discussion among scientists about null-hypothesis significance testing and Bayesian data analysis has led to speculation about the practices and consequences of "researcher degrees of freedom." This article advances this debate by asking the broader questions that we, as scientists, should be asking: How do scientists make decisions in the course of doing research, and what is the impact of these decisions on scientific conclusions? We asked practicing scientists to collect data in a simulated research environment, and our findings show that some scientists use data collection heuristics that deviate from prescribed methodology. Monte Carlo simulations show that data collection heuristics based on p values lead to biases in estimated effect sizes and Bayes factors and to increases in both false-positive and false-negative rates, depending on the specific heuristic. We also show that using Bayesian data collection methods does not eliminate these biases. Thus, our study highlights the little appreciated fact that the process of doing science is a behavioral endeavor that can bias statistical description and inference in a manner that transcends adherence to any particular statistical framework.

TL;DR: Although the method is based on a nonclassical version of simple type theory, it is intended as a guide for theory interpretation in classical simple type theories as well as in predicate logics with partial functions.
Abstract: Theory interpretation is a logical technique for relating one axiomatic theory to another with important applications in mathematics and computer science as well as in logic itself. This paper presents a method for theory interpretation in a version of simple type theory, called lutins, which admits partial functions and subtypes. The method is patterned on the standard approach to theory interpretation in first-order logic. Although the method is based on a nonclassical version of simple type theory, it is intended as a guide for theory interpretation in classical simple type theories as well as in predicate logics with partial functions.

TL;DR: A novel approach to estimating healthcare fraud (HCF) risk that applies network algorithms to graphs derived from open source datasets that calculates behavioral similarity to known fraudulent and non-fraudulent healthcare providers with respect to measurable healthcare activities.
Abstract: This paper presents a novel approach to estimating healthcare fraud (HCF) risk that applies network algorithms to graphs derived from open source datasets. One group of algorithms calculates behavioral similarity to known fraudulent and non-fraudulent healthcare providers with respect to measurable healthcare activities, such as medical procedures and drug prescriptions. Another set of algorithms estimates propagation of risk from fraudulent healthcare providers through geospatial collocation, i.e., shared practice locations or other addresses. The algorithms were evaluated with respect to their ability to predict a provider's presence on the Office of the Inspector General's list of providers excluded from participation in Medicare and other Federal healthcare programs (exclusion). In an empirical evaluation, a combination of 11 features achieved an f-score of 0.919 and a ROC area of 0.960 in exclusion prediction. An ablation analysis showed that most of this predictive accuracy was the result of features that measure risk propagation through geospatial collocation.

TL;DR: Although the monkey offers a more appropriate model for studying the toxic effects of inhaled substances on the nasal passages and extrapolating the findings to humans, the rat, which is very different from humans, is a poor model.
Abstract: While nasal cancer is relatively rare among the general population, workers in the nickel refining, leather manufacturing, and furniture building industries exhibit increased incidences of nasal cancer. To investigate the causes of nasal cancer and to design ameliorative strategies, an appropriate animal model for the human upper respiratory regions is required. The present report describes, compares, and assesses the anatomy and physiology of the nasal passages and upper airways of humans, rats, and monkeys for the purpose of determining a relevant animal model in which to investigate potential causes of nasal cancer. Based on the mode of breathing, overall geometry of the nasal passages, relative nasal surface areas, proportions of nasal surfaces lined by various epithelia, mucociliary clearance patterns, and inspiratory airflow routes, the rat, which is very different from humans, is a poor model. In contrast, the monkey exhibits many similarities to humans. Although the monkey does differ from humans in that it exhibits a more rapid respiratory rate, smaller minute and tidal volumes, larger medial turbinate, and a vestibular wing that creates an anterior vortex during inspiration, it offers a more appropriate model for studying the toxic effects of inhaled substances on the nasal passages and extrapolating the findings to humans.
