In this article, I explore issues of commitment to truth in dating ads that use apparently impossible categorizations to project identities for ad writers and their desired others. The article begins with a brief overview of relevant aspects of Text World Theory (especially Gavins's work on dating ads), Sinclair's model of fictional worlds and Routledge and Chapman's account of truth-commitment in discourse, and proposes the need for a framework that allows for a partial suspension of commitment to truth. I then draw on the work of Ivanič and Weldon on identity in writing, in order to develop an account that offers a discourse- and genre-based discussion of how the intertextual metaphors in such ads are interpreted in relation to truth values. I suggest the default stance is that of positive commitment to literal truth and that, when this is not possible, a fall-back mode of negative commitment to metaphorical truth is preferred over an interpretation in which questions of truth are truly suspended. Finally, I consider a related category, of apparently negative dating ad identities, in order to suggest a functional motivation for the inclusion of elements that cannot be interpreted in truth-committed mode.

Deception research has traditionally focused on three methods of identifying liars and truth tellers: observing non-verbal or behavioral cues, analyzing verbal cues, and monitoring changes in physiological arousal during polygraph tests. Research shows that observers are often incapable of discriminating between liars and truth tellers with better than chance accuracy when they use these methods. One possible explanation for observers' poor performance is that they are not properly applying existing lie detection methods. An alternative explanation is that the cues on which these methods — and observers' judgments — are based do not reliably discriminate between liars and truth tellers. It may be possible to identify more reliable cues, and potentially improve observers' ability to discriminate, by developing a better understanding of how liars and truth tellers try to tell a convincing story. ^ This research examined (a) the verbal strategies used by truthful and deceptive individuals during interviews concerning an assigned activity, and (b) observers' ability to discriminate between them based on their verbal strategies. In Experiment I, pre-interview instructions manipulated participants' expectations regarding verifiability; each participant was led to believe that the interviewer could check some types of details, but not others, before deciding whether the participant was being truthful or deceptive. Interviews were then transcribed and scored for quantity and type of information provided. In Experiment II, observers listened to a random sample of the Experiment I interviews and rendered veracity judgments; half of the observers were instructed to judge the interviews according to the verbal strategies used by liars and truth tellers and the other half were uninstructed. ^ Results of Experiment I indicate that liars and truth tellers use different verbal strategies, characterized by a differential amount of detail. Overall, truthful participants provided more information than deceptive participants. This effect was moderated by participants' expectations regarding verifiability such that truthful participants provided more information only with regard to verifiable details. Results of Experiment II indicate that observers instructed about liars' and truth tellers' verbal strategies identify them with greater accuracy than uninstructed observers. ^

Individual cues to deception are subtle and often missed by lay people and law enforcement alike. Linguistic statement analysis remains a potentially useful way of overcoming individual diagnostic limitations (e.g. Criteria based Content Analysis; Steller & Köhnken, 1989; Reality monitoring; Johnson & Raye, 1981; Scientific Content Analysis; Sapir, 1996). Unfortunately many of these procedures are time-consuming, require in-depth training, as well as lack empirical support and/or external validity. The current dissertation develops a novel approach to statement veracity analysis that is simple to learn, easy to administer, theoretically sound, and empirically validated. Two strategies were proposed for detecting differences between liars' and truth-tellers' statements. Liars were hypothesized to strategically write statements with the goal of self-exoneration. Liars' statements were predicted to contain more first person pronouns and fewer third person pronouns. Truth-tellers were hypothesized to be motivated toward being informative and thus produce statements with fewer first person pronouns and more third person pronouns. Three studies were conducted to test this hypothesis. The first study explored the verbal patterns of exoneration and informativeness focused statements. The second study used a traditional theft paradigm to examine these verbal patterns in guilty liars and innocent truth tellers. In the third study to better match the context of a criminal investigation a cheating paradigm was used in which spontaneous lying was induced and written statements were taken. Support for the first person pronoun hypothesis was found. Limited support was found for the third person pronoun hypothesis. Results, implications, and future directions for the current research are discussed.

This collection of essays is the first time a group of theatre historians have come together to consider the challenge of applying ethical thinking to attempts to truthfully represent the past. Topics include the life of the celebrated Restoration actor Thomas Betterton, the little-known records of hitherto forgotten women involved in Victorian theatre, amateur theatricals enjoyed by the British army in colonial India, the loss of a pioneering arts centre for African and Caribbean culture, performance art in Wales and present-day community arts in Northern Ireland. While confronting such difficult issues as the instability of evidence and the unreliability of memory, the contributors offer fresh perspectives and innovative strategies for fulfilling their ethical responsibility to the lived experience of the past.

Preface by the editor contains this statement: "Several years since there was what purported to be a translation published in London; but this was a disgraceful imposture. Mrs. Austin speaks of it as the most flagrant piece of literary dishonesty on record, not without justice; and Mr. Carlyle refers to it much in the same spirit. It was a poor copy of a wretched French version, in which frequently twenty pages of the original are omitted at a time, and hardly a sentence is rendered with fidelity." This refers to an anonymous translation published in 2 vols., London, 1824, and reprinted in 1 vol., New York, 1824 and 1844. cf. Characteristics of Goethe. From the German of Falk, von Müller, etc., with notes ... by S. Austin, vol. II (1833) p. 129, and Carlyle's Crit. and miscell. essays, New York, 1872, vol. I, p. 178.

In order to evaluate the effects of uncertainty about direction of mechanical perturbation and supra-postural task constraint on postural control young adults had their upright stance perturbed while holding a tray in a horizontal position Stance was perturbed by moving forward or backward a supporting platform contrasting situations of certainty versus uncertainty of direction of displacement Increased constraint on postural stability was Imposed by a supra-postural task of equilibrating a cylinder on the tray Performance was assessed through EMG of anterior leg muscles angular displacement of the main Joints involved in the postural reactions and displacement of the tray Results showed that both certainty on the direction of perturbation and Increased supra-postural task constraint led to decreased angular displacement of the knee and the hip Furthermore combination of certainty and high supra-postural task constraint produced shorter latency of muscular activation Such postural responses were paralleled by decreased displacement of the tray Thesi results suggest a functional integration between the tasks with central set priming reactive postural responses from contextual cues and Increased stability demand (C) 2010 Elsevier B V All rights reserved

Interpretability and power of genome-wide association studies can be increased by imputing unobserved genotypes, using a reference panel of individuals genotyped at higher marker density. For many markers, genotypes cannot be imputed with complete certainty, and the uncertainty needs to be taken into account when testing for association with a given phenotype. In this paper, we compare currently available methods for testing association between uncertain genotypes and quantitative traits. We show that some previously described methods offer poor control of the false-positive rate (FPR), and that satisfactory performance of these methods is obtained only by using ad hoc filtering rules or by using a harsh transformation of the trait under study. We propose new methods that are based on exact maximum likelihood estimation and use a mixture model to accommodate nonnormal trait distributions when necessary. The new methods adequately control the FPR and also have equal or better power compared to all previously described methods. We provide a fast software implementation of all the methods studied here; our new method requires computation time of less than one computer-day for a typical genome-wide scan, with 2.5 M single nucleotide polymorphisms and 5000 individuals.

The family doctor facing complexity must decide in situations of low certainty and low agreement. Complexity is in part subjective but can also be measured. Changes in the health systems aim to reduce health costs. They tend to give priority to simple situations and to neglect complexity. One role of an academic institute of family medicine is to present and promote the results of scientific research supporting the principles of family medicine, taking into account both the local context and health systems reforms. In Switzerland the new challenge is the introduction of managed care.

Under EU competition law, parent companies may be held jointly and severally liable for the competition law infringements committed by their subsidiaries. The possibility of holding parent companies liable demonstrates a significant exception from the idea of separate legal entities. However, it is not the only deviation developed under EU competition law. In cases, where the legal entity responsible for the anti-competitive conduct has changed its form, liability can be attributed to the new operator, in particular, to its successor. The principles of legal certainty and legitimate expectations are issues that surround the doctrines of parental and successor liability. The aim of this thesis is to present a comprehensive comparative analysis of the parental and successor liability doctrines and to clarify the conditions under which it is possible to attribute liability for the infringements of EU competition law. The main purpose is therefore to demonstrate the problems related to the allocation of liability and to discuss whether these liability principles, established to assure the effective enforcement of the EU competition rules, are good solutions. The research methods used in this thesis are the legal dogmatic approach and the comparative law approach. The former enables the possibility of using the case law and legislation as a framework in which the difficulties concerning the application of parental and successor liability can be discussed while the latter ensures the comparison of the characteristics and judgments. The doctrines of parental and successor liability are both well established, but the application practice has caused several difficulties. These problems derive from, inter alia, the broadness and disjointed developed of the doctrines. There has been much recent case law dealing with these issues and having the potential to open up a considerable risk and to allocate strict liability for parent and successor companies.
