Relations between connected and self-avoiding walks in a digraph

Walks in a directed graph can be given a partially ordered structure that extends to possibly unconnected objects, called hikes. Studying the incidence algebra on this poset reveals unsuspected relations between walks and self-avoiding hikes. These relations are derived by considering truncated versions of the characteristic polynomial of the weighted adjacency matrix, resulting in a collection of matrices whose entries enumerate the self-avoiding hikes of length $\ell$ from one vertex to another

Enkinaesthetic polyphony: the underpinning for first-order languaging

We contest two claims: (1) that language, understood as the processing of abstract symbolic forms, is an instrument of cognition and rational thought, and (2) that conventional notions of turn-taking, exchange structure, and move analysis, are satisfactory as a basis for theorizing communication between living, feeling agents. We offer an enkinaesthetic theory describing the reciprocal affective neuro-muscular dynamical flows and tensions of co- agential dialogical sense-making relations. This “enkinaesthetic dialogue” is characterised by a preconceptual experientially recursive temporal dynamics forming the deep extended melodies of relationships in time. An understanding of how those relationships work, when we understand and are ourselves understood, when communication falters and conflict arises, will depend on a grasp of our enkinaesthetic intersubjectivity

Narrative Discourse as a Multi-Level System of Communication: Some Theoretical Proposals Concerning Bakhtin\u27s Dialogic Principle

This article attempts to show that the dialogizing of narrative discourse is a way of de-naturalizing the fictional process and its associated textual activities by reconstituting the material interplay of voices (in Bakhtin\u27s pioneering sense). It is this interplay which is suppressed by the convention of a single, univocal narrative position. This corresponds to Bakhtin\u27s notion of monologic discourse, which implies an already given, objectified identity lying behind the text. Dialogic discourse restores to textual practice the material interplay of frequently opposing and contradictory semantic and ideological positions which actively constitute the formation of discourse. These voices which are constantly re-interpreted and transformed in dialogic discourse will help to show that the Subject is not external to discursive practices, but it is continually re-constituted and transformed within specific discursive formations. The second part of this article contains a detailed analysis of an excerpt from Vladimir Nabokov\u27s novel Ada. Following this are a number of proposals or strategies for understanding the processes of dialogic interaction which take place across levels in the narrative text

Estimating the transition matrix of a Markov chain observed at random times

In this paper we develop a statistical estimation technique to recover the transition kernel $P$ of a Markov chain $X=(X_m)_{m \in \mathbb N}$ in presence of censored data. We consider the situation where only a sub-sequence of $X$ is available and the time gaps between the observations are iid random variables. Under the assumption that neither the time gaps nor their distribution are known, we provide an estimation method which applies when some transitions in the initial Markov chain $X$ are known to be unfeasible. A consistent estimator of $P$ is derived in closed form as a solution of a minimization problem. The asymptotic performance of the estimator is then discussed in theory and through numerical simulations

The Epidemiology of Respiratory Infections in Mobile Populations

Respiratory Tract Infections (RTIs) in mobile populations such as travellers are prevalent and can escalate into severe illnesses. Timely identification and treatment of these conditions are imperative to prevent disease progression. This thesis aims to to evaluate the epidemiology of RTIs in travellers and mobile populations using mobile applications

Corpus and Models for Lemmatisation and POS-tagging of Classical French Theatre

This paper describes the process of building an annotated corpus and training models for classical French literature, with a focus on theatre, and particularly comedies in verse. It was originally developed as a preliminary step to the stylometric analyses presented in Cafiero and Camps [2019]. The use of a recent lemmatiser based on neural networks and a CRF tagger allows to achieve accuracies beyond the current state-of-the art on the in-domain test, and proves to be robust during out-of-domain tests, i.e.up to 20th c.novels

Applications of multimodal concordances

Multimodal corpus linguistics has so far been a theoretical rather than an applicative discipline. This paper sketches out proposals that attempt to bridge between these two perspectives. It does so with particular reference to the development of the conceptual and software tools required to create and concordance multimodal corpora from the applicative standpoint and as such is designed to underpin the study of texts at universities in foreign-language teaching and testing cycles. One branch of this work relates to multimedia language tests which, as illustrated in Section 2, use concordancing techniques to analyze multimodal texts in relation to students’ understanding of oral and written forms of discourse in English. Another branch is the exploration of multimodal tests concerned with the explicit assessment of students’ knowledge of the principles and/or models of textual organization of multimodal texts. The two types of test are not mutually exclusive. A third branch of research thus relates to the development of hybrid tests which, for example, combine a capacity to analyze multimodal texts with an assessment of students’ language skills, such as fluency in speaking and writing in English or which ascertain the multimodal literacy competencies of students and the differing orientations to meaning-making styles that individuals manifest. The paper considers these different applicative perspectives by describing the different categories of concordance achievable with the MCA online concordancer (Section 2) and by defining their relevance to multimodal discourse analysis (Section 3). It also illustrates the use of meaning-oriented multimodal concordances in the creation and implementation of multimodal tests (Sections 4). It concludes by suggesting that the re-interpretation of the nature and functions of concordances is long overdue and that the exploration of new types of concordance is salutary for linguistics and semiotics in general
