Communication modality and attitude change in a realistic experiment

In this experiment, an experimental interview with the leader of the Socialists in the Dutch Parliament was delivered via three different media: television, radio, or a newspaper presentation. We showed that the experimental interviews led, in themselves, to attitude change, but no difference was found among the three communication modalities. Moreover, no significant interaction effect was established between the political preference of the subjects (Socialist versus non-Socialist) and communication modality. Our main results do not support the assumption that for a well-known politician presently holding office, television is a less effective medium than radio or newspaper

The representation of conflict in the discourse of Italian melodrama

This paper is part of an extensive study of cinematic dialogue in a variety of film genres in Italian, which aims to address the disregard for the verbal plane that characterises film theory and, particularly, genre theory. Assuming a pragmatic and functional semantic perspective, it analyses the scripted dialogues in films against the backdrop of the literature on real life discourse. The focus of the paper is confrontational talk in Italian melodramas from early 1960s to the present. Conflict in such films is, to an extent, comparable to the cooperative sequential rebuttal of speakers' turns that typically occurs in comedies. However, melodramas are also marked by more incisive and subtle patterns of confrontation that can be summarised as 'disaffiliative dysfluency'. The forms of such break in the conversational flow are discussed and illustrated with selected scenes from a number of films

Revisiting the Core Ontology and Problem in Requirements Engineering

In their seminal paper in the ACM Transactions on Software Engineering and Methodology, Zave and Jackson established a core ontology for Requirements Engineering (RE) and used it to formulate the "requirements problem", thereby defining what it means to successfully complete RE. Given that stakeholders of the system-to-be communicate the information needed to perform RE, we show that Zave and Jackson's ontology is incomplete. It does not cover all types of basic concerns that the stakeholders communicate. These include beliefs, desires, intentions, and attitudes. In response, we propose a core ontology that covers these concerns and is grounded in sound conceptual foundations resting on a foundational ontology. The new core ontology for RE leads to a new formulation of the requirements problem that extends Zave and Jackson's formulation. We thereby establish new standards for what minimum information should be represented in RE languages and new criteria for determining whether RE has been successfully completed.Comment: Appears in the proceedings of the 16th IEEE International Requirements Engineering Conference, 2008 (RE'08).

An Eye for an Eye: Impact of Sequelization and Comparison in Advertisements on Consumer’s Perception of Brands

In this paper we demonstrate that the positive effects of comparative advertising are significantly diluted when a compared-to brand retaliates. Retaliation introduces sequencing in advertisements. We therefore evaluate sequelized advertisements (both comparative and noncomparative) alongside comparative advertisements and ordinary advertisements. We show that, given no threat of comparative advertising from competitors, sequelizing a popular advertisement may be as potent as comparative advertising, in terms of improving consumers’ recall as well as preference for the sponsored brand. Furthermore, an advertisement message may be directed at core benefits (and/or attributes) that a brand promises, or at a stylized theme or storyline that use peripheral cues to indirectly convey the brand’s deliverables. We incorporate this dimension of communication focus and conclude that while comparative advertisements are more effective with objective messages, noncomparative sequelized advertisements work better with thematic or story based messages.

Predicting satisfaction: perceived decision quality by decision-makers in Web-based group decision support systems

In future, the organizations' likelihood to endure and succeed will depend greatly on the quality of every decision made. It is known that most decisions in organizations are made in group. With the purpose of supporting decision-makers anytime and anywhere, Web-based Group Decision Support Systems (GDSS) have been studied. The amount of Web-based GDSS incorporating automatic negotiation mechanisms such as argumentation has been steadily increasing. Usually, these systems/models are evaluated through mathematical proofs, number of rounds or seconds to propose (reach) a solution. However, those techniques are not very informative in terms of the decision quality. Here, we propose a model that intends to predict the decision-makers' satisfaction (perception of the decision quality), specifically designed to deal with multi-criteria problems. Our model considers aspects such as: meeting's outcomes, decision-maker's intentions, expectations and emotional cost. To validate the proposed model in terms of its ability to predict decision-makers' satisfaction, we developed a prototype of a Web-based GDSS to be used in a case study where the participant had to make a joint decision. The decision process consisted in a set of 5 rounds, where the participant could (re) configure his/her preferences along the process. The satisfaction model ascertained its ability to predict the participants' satisfaction and allowed to understand that (as is stated in the literature) the inclusion of cognitive and emotional variables is essential to evaluate satisfaction more accurately.This paper is a revised and an expanded version of a paper entitled "Evaluating the Perception of the Decision Quality in Web-Based Group Decision Support Systems: A Theory of Satisfaction" presented at International Conference on Practical Applications of Agents and Multi-Agent Systems 2017, Porto, Portugal [12].

Labeled bipolar argumentation frameworks

An essential part of argumentation-based reasoning is to identify arguments in favor and against a statement or query, select the acceptable ones, and then determine whether or not the original statement should be accepted. We present here an abstract framework that considers two independent forms of argument interaction-support and conflict-and is able to represent distinctive information associated with these arguments. This information can enable additional actions such as: (i) a more in-depth analysis of the relations between the arguments; (ii) a representation of the user's posture to help in focusing the argumentative process, optimizing the values of attributes associated with certain arguments; and (iii) an enhancement of the semantics taking advantage of the availability of richer information about argument acceptability. Thus, the classical semantic definitions are enhanced by analyzing a set of postulates they satisfy. Finally, a polynomial-time algorithm to perform the labeling process is introduced, in which the argument interactions are considered.Fil: Escañuela Gonzalez, Melisa Gisselle.

Consideration Sets and Competitive Marketing

We study a market model in which competing firms use costly marketing devices to influence the set of alternatives which consumers perceive as relevant. Consumers in our model are boundedly rational in the sense that they have an imperfect perception of what is relevant to their decision problem. They apply well-defined preferences to a "consideration set", which is a function of the marketing devices employed by the firms. We examine the implications of this behavioral model in the context of a competitive market model, particularly on industry profits, vertical product differentiation, the use of marketing devices and consumers' conversion rates.consideration sets, marketing, industrial organization, advertising, default bias, inertia, product display, bounded rationality, limited attention, persuasion

Enlightened Romanticism: Mary Gartside’s colour theory in the age of Moses Harris, Goethe and George Field

The aim of this paper is to evaluate the work of Mary Gartside, a British female colour theorist, active in London between 1781 and 1808. She published three books between 1805 and 1808. In chronological and intellectual terms Gartside can cautiously be regarded an exemplary link between Moses Harris, who published a short but important theory of colour in the second half of the eighteenth century, and J.W. von Goethe’s highly influential Zur Farbenlehre, published in Germany in 1810. Gartside’s colour theory was published privately under the disguise of a traditional water colouring manual, illustrated with stunning abstract colour blots (see example above). Until well into the twentieth century, she remained the only woman known to have published a theory of colour. In contrast to Goethe and other colour theorists in the late 18th and early 19th century Gartside was less inclined to follow the anti-Newtonian attitudes of the Romantic movement
