Improvising Linguistic Style: Social and Affective Bases for Agent Personality

This paper introduces Linguistic Style Improvisation, a theory and set of algorithms for improvisation of spoken utterances by artificial agents, with applications to interactive story and dialogue systems. We argue that linguistic style is a key aspect of character, and show how speech act representations common in AI can provide abstract representations from which computer characters can improvise. We show that the mechanisms proposed introduce the possibility of socially oriented agents, meet the requirements that lifelike characters be believable, and satisfy particular criteria for improvisation proposed by Hayes-Roth.Comment: 10 pages, uses aaai.sty, lingmacros.sty, psfig.st

Business and/or Ethics? A Framework for Resolving Multicriteria Decision Dilemmas

Corporate leadership is often in the unenviable position of balancing ethical choices and profit. Business decisions consider alternatives and make choices to further strategic business goals. Measures of business success are likely to be financial, including profit, revenue, sales, market share, cost of production, quality of products, innovative product development. Ethical decisions are choices among right and wrong outcomes or processes. Assessment of ethical choices may or may not be easily quantified, including consideration of positive and negative consequences, moral principles, and fair process. Inevitably, then, the inherent nature of business-ethics decisions will involve multiple decision criteria, including both business criteria and ethics criteria. These criteria may conflict, creating dilemmas that may be difficult to resolve. Sometimes ethical business decisions will be profitable, sometimes ethical business decisions will be more costly than less ethical alternatives and therefore be less profitable. Multicriteria analysis tools are designed for such decision dilemmas, yet responsibility inheres to the people who must choose. Conclusions are drawn for individual, corporate, and algorithmic decisions. Decision processes should answer these questions: Are units of measure comparable? Is the system open or closed? Is it deterministic or stochastic? Is there a risk to life? Who is responsible? Is the decision process transparent? Who cares about the outcome? What are their criteria for successful consequences? What ethical principles apply

Privacy Ethics in Biblical Literature

This paper combines modern legal scholars\u27 and biblical literature\u27s treatment of a right to privacy. Beginning with a reassessment of Warren & Brandeis\u27 right to be let alone as the first legal treatment of a right to privacy, the authors explore the right to privacy’s roots in ancient ethical standards. This is done via a study of privacy as it is treated in biblical literature. What emerge are two themes that are central to ethical decision-making with regard to privacy. The first is that breaches of privacy are irreversible, an idea that is informative as to why privacy is valued so highly. The second addresses the decision dilemmas that arise when privacy and its underlying values conflict with other rights and values. These dilemmas confront business executives, technology developers and engineers, government agents, press and media managers, and others who need to decide how to protect privacy in situations not yet covered by existing privacy laws. These front-line decision makers must make judgments based on pre-existing ethical precepts and traditions because often privacy laws lag behind the problems they are written to address

Next-to-leading order QCD corrections to Z boson pair production via vector-boson fusion

Vector-boson fusion processes are an important tool for the study of electroweak symmetry breaking at hadron colliders, since they allow to distinguish a light Higgs boson scenario from strong weak boson scattering. We here consider the channels WW->ZZ and ZZ->ZZ as part of electroweak Z boson pair production in association with two tagging jets. We present the calculation of the NLO QCD corrections to the cross sections for p p -> e+ e- mu+ mu- + 2 jets and p p -> e+ e- nu_mu nubar_mu + 2 jets via vector-boson fusion at order alpha_s alpha^6, which is performed in the form a NLO parton-level Monte Carlo program. The corrections to the integrated cross sections are found to be modest, while the shapes of some kinematical distributions change appreciably at NLO. Residual scale uncertainties typically are at the few percent level.Comment: 12 pages, 4 figure

Azimuthal Correlation in Lepton-Hadron Scattering via Charged Weak-Current Processes

We consider the azimuthal correlation of the final-state particles in charged weak-current processes. This correlation provides a test of perturbative quantum chromodynamics. The azimuthal asymmetry is large in the semi-inclusive processes in which we identify a final-state hadron, say, a charged pion compared to that in the inclusive processes in which we do not identify final-state particles and use only the calorimetric information. In semi-inclusive processes the azimuthal asymmetry is more conspicuous when the incident lepton is an antineutrino or a positron than when the incident lepton is a neutrino or an electron. We analyze all the possible charged weak-current processes and study the quantitative aspects of each process. We also compare this result to the ep scattering with a photon exchange.Comment: 25 pages, 2 Postscript figures, uses RevTeX, fixes.st

“I just want to be skinny.”: A content analysis of tweets expressing eating disorder symptoms

There is increasing concern about online communities that promote eating disorder (ED) behaviors through messages and/or images that encourage a “thin ideal” (i.e., promotion of thinness as attractive) and harmful weight loss/weight control practices. The purpose of this paper is to assess the content of body image and ED-related content on Twitter and provide a deeper understanding of EDs that may be used for future studies and online-based interventions. Tweets containing ED or body image-related keywords were collected from January 1-January 31, 2015 (N = 28,642). A random sample (n = 3000) was assessed for expressions of behaviors that align with subscales of the Eating Disorder Examination (EDE) 16.0. Demographic characteristics were inferred using a social media analytics company. The comprehensive research that we conducted indicated that 2,584 of the 3,000 tweets were ED-related; 65% expressed a preoccupation with body shape, 13% displayed issues related to food/eating/calories, and 4% expressed placing a high level of importance on body weight. Most tweets were sent by girls (90%) who were ≤19 years old (77%). Our findings stress a need to better understand if and how ED-related content on social media can be used for targeting prevention and intervention messages towards those who are in-need and could potentially benefit from these efforts.</div

An intermediate-mass Higgs boson in two-photon coherent processes at the LHC

We reexamine the prospects of searching for a neutral Higgs boson in the intermediate-mass range, using the proton- and ion-beam facilities of the LHC to study coherent two-photon processes. Considering realistic design luminosities for the different ion beams, we find that beams of light-to-medium size ions like calcium will give the highest production rates. With a suitable trigger and assuming a b-quark identification efficiency of $30\%$ and a $b{\bar b}$ mass resolution of 10 GeV one could expect to see a Higgs signal in the $b{\bar b}$ channel with a 3-4 $\sigma$ statistical significance in the first phase of operation of the LHC with beams of calcium.Comment: 10 pages of LATEX + 3 Figures (postscript

Phase-ordering of conserved vectorial systems with field-dependent mobility

The dynamics of phase-separation in conserved systems with an O(N) continuous symmetry is investigated in the presence of an order parameter dependent mobility M(\phi)=1-a \phi^2. The model is studied analytically in the framework of the large-N approximation and by numerical simulations of the N=2, N=3 and N=4 cases in d=2, for both critical and off-critical quenches. We show the existence of a new universality class for a=1 characterized by a growth law of the typical length L(t) ~ t^{1/z} with dynamical exponent z=6 as opposed to the usual value z=4 which is recovered for a<1.Comment: RevTeX, 8 pages, 13 figures, to be published in Phys.
