    This report shows that neighborhoods play an important role in determining a family's prospects of moving up the economic ladder. Metropolitan areas where the wealthy and poor live apart have lower mobility than areas where residents are more economically integrated

    Learning Language Representations for Typology Prediction

    Full text link
    One central mystery of neural NLP is what neural models "know" about their subject matter. When a neural machine translation system learns to translate from one language to another, does it learn the syntax or semantics of the languages? Can this knowledge be extracted from the system to fill holes in human scientific knowledge? Existing typological databases contain relatively full feature specifications for only a few hundred languages. Exploiting the existence of parallel texts in more than a thousand languages, we build a massive many-to-one neural machine translation (NMT) system from 1017 languages into English, and use this to predict information missing from typological databases. Experiments show that the proposed method is able to infer not only syntactic, but also phonological and phonetic inventory features, and improves over a baseline that has access to information about the languages' geographic and phylogenetic neighbors.Comment: EMNLP 201

    Emotion words and categories: evidence from lexical decision

    We examined the categorical nature of emotion word recognition. Positive, negative, and neutral words were presented in lexical decision tasks. Word frequency was additionally manipulated. In Experiment 1, "positive" and "negative" categories of words were implicitly indicated by the blocked design employed. A significant emotion–frequency interaction was obtained, replicating past research. While positive words consistently elicited faster responses than neutral words, only low frequency negative words demonstrated a similar advantage. In Experiments 2a and 2b, explicit categories ("positive," "negative," and "household" items) were specified to participants. Positive words again elicited faster responses than did neutral words. Responses to negative words, however, were no different than those to neutral words, regardless of their frequency. The overall pattern of effects indicates that positive words are always facilitated, frequency plays a greater role in the recognition of negative words, and a "negative" category represents a somewhat disparate set of emotions. These results support the notion that emotion word processing may be moderated by distinct systems

    An Ethical Basis for Relationship Marketing: A Virtue Ethics Perspective

    Get PDF
    Purpose – The purpose of this paper is to provide an ethical foundation for relationship marketing using a virtue ethics approach. Design/methodology/approach – The approach is a conceptual one providing a background on relationship marketing from both American and European perspectives. Earlier studies published in EJM on relationship marketing are featured in a table. Findings – The proposed ethical relationship marketing approach has three stages (establishing, sustaining and reinforcing) that are paired with specific virtues (trust, commitment and diligence). These and other facilitating virtues are shown in a figure. Research limitations/implications – The model and its components have yet to be tested empirically. Some strategies for undertaking such research are discussed. Practical implications – Several European and American companies that currently practice ethical relationship marketing are discussed. Originality/value – Although relationship marketing has been studied for a number of years by many scholars, the ethical basis of it has not been thoroughly examined in any previous work
