Influencing Choices by Changing Beliefs: A Logical Theory of Influence, Persuasion, and Deception

Wemodelpersuasion,viewedasadeliberateactionthroughwhichan agent (persuader) changes the beliefs of another agent’s (persuadee). This notion of persuasion paves the way to express the idea of persuasive influence, namely inducing a change in the choices of the persuadee by changing her beliefs. It allows in turns to express different aspects of deception. To this end, we propose a logical framework that enables expressing actions and capabilities of agents, their mental states (desires, knowledge and beliefs), a variety of agency operators as well as the connection between mental states and choices. Those notions, once combined, enable us to capture, the notion of influence, persuasion and deception, as well as their relation

Lymphomatoid papulosis localized to the oral mucosa: case report and literature review

Introduction: Lymphomatoid papulosis is a primary CD 30+ cutaneous lymphoproliferation. Observation: We report the case of a 39-year-old patient who presented with ulcers on the back of the tongue, gums, buccal mucosa, and soft palate, which evolved as spontaneously regressive flare-ups. The diagnosis of inflammatory bowel disease was initially proposed. Several years later, the patient presented an ulcer on the left middle finger. Histological examination confirmed the diagnosis of lymphomatoid papulosis. Discussion: This chronic dermatosis manifests a single rash or multiple papulonodular rashes, evolving as spontaneously regressive flare-ups. Mucosal involvement is rare, and no prognostic factor for this location has been highlighted to this date. Pathological examination is essential. Conclusion: The mucosal involvement of lymphomatoid papulosis is one of the diagnoses to be considered for recurrent mouth ulcers
