Our goal is to use natural language processing to identify deceptive and nondeceptive passages in transcribed narratives. We begin by motivating an analysis of language-based deception that relies on specific linguistic indicators to discover deceptive statements. The indicator tags are assigned to a document using a mix of automated and manual methods. Once the tags are assigned, an interpreter automatically discriminates between deceptive and truthful statements based on tag densities. The texts used in our study come entirely from "real world" sources-criminal statements, police interrogations and legal testimony. The corpus was hand-tagged for the truth value of all propositions that could be externally verified as true or false. Classification and Regression Tree techniques suggest that the approach is feasible, with the model able to identify 74.9% of the T/F propositions correctly. Implementation of an automatic tagger with a large subset of tags performed well on test data, producing an average score of 68.6% recall and 85.3% preci
Hospitals providing maternity care influence breastfeeding mothers and infants during the critical, early postnatal period. Despite concerted public health efforts, there are persistent, large variations across New York State (NYS) hospitals in breastfeeding policies, maternity care, and infant feeding practices and in rates of breastfeeding initiation and exclusivity. An initiative addressing this issue is the Breastfeeding Quality Improvement in Hospitals (BQIH) Learning Collaborative, which was designed and implemented by the NYS Department of Health (NYSDOH). The BQIH Learning Collaborative, adapted from the Institute for Healthcare Improvement Breakthrough Series, embedded evidence-based maternity care best practices in a learning and quality improvement model. The Ten Steps to Successful Breastfeeding served as the backbone for improvement with the aims of increasing the percentages of infants fed any breastmilk and exclusively fed breastmilk while decreasing the percentage of breastfed infants supplemented with formula. Twelve hospitals were selected to participate based on their breastfeeding metrics: 10 of the hospitals were low performing, and two were high performing on these breastfeeding measures. During the 18-month BQIH Learning Collaborative, process improvement occurred for several measures, including breastfeeding within the first hour after birth, breastfeeding mother/infant rooming-in, and receipt of formula samples/discharge bags. NYSDOH plans to spread this Collaborative to all hospitals providing maternity care in NYS. Comprehensive breastfeeding initiatives will continue in NYS in the effort to ensure that all breastfeeding mothers receive optimal support from healthcare providers and hospitals with the goal of making breastfeeding the norm for infant nutrition during the first year of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
