Reverse-safe data structures for text indexing
2021
We introduce the notion of reverse-safe data structures. These are data structures that prevent the reconstruction of the data they encode (i.e., they cannot be easily reversed). A data structure D is called z-reverse-safe when there exist at least z datasets with the same set of answers as the ones stored by D. The main challenge is to ensure that D stores as many answers to useful queries as possible, is constructed efficiently, and has size close to the size of the original dataset it encodes. Given a text of length n and an integer z, we propose an algorithm which constructs a z-reverse-safe data structure that has size O(n) and answers pattern matching queries of length at most d optim…
Deep neural attention-based model for the evaluation of italian sentences complexity
2020
In this paper, the Automatic Text Complexity Evaluation problem is modeled as a binary classification task tackled by a Neural Network based system. It exploits Recurrent Neural Units and the Attention mechanism to measure the complexity of sentences written in the Italian language. An accurate test phase has been carried out, and the system has been compared with state-of-art tools that tackle the same problem. The computed performances proof the model suitability to evaluate sentence complexity improving the results achieved by other state-of-the-art systems.
Using discourse markers to negotiate epistemic stance: A view from situated language use
2021
Abstract In this paper, I analyse the usage of a discourse marker =mari, belonging to the epistemic paradigm attested in Upper Napo Kichwa (Quechuan, Ecuador). I show that the use of =mari indicates that the information is known well to the speaker, but also to some extent familiar to the addressee. In situated language use, the marker contributes to creating a knowing epistemic stance of the speaker. The analysis presented here is based on a 13-h documentary corpus of interactive Upper Napo Kichwa discourse, recorded on audio and video. For the purpose of the paper, the relevant utterances are analysed in their broad interactional context, including not only the surrounding text, but also …
Speaking out against everyday sexism : Gender and epistemics in accusations of “mansplaining”
2021
In everyday interaction, subtle manifestations of sexism often pass unacknowledged and become internalised and thus perceived as “natural” conduct. The introduction of new vocabularies for referring to previously unnamed sexist conduct would presumably enable individuals to start problematising hitherto unchallengeable sexism. In this paper, we investigate whether and how these vocabularies empower people to speak out against sexism. We focus on the use of the term “mansplaining” which, although coined over 10 years ago, remains controversial and contested. Using Conversation Analysis and Membership Categorisation Analysis, this paper excavates the interactional methods individuals use to f…
Association of parental communication deviance with offspring's psychiatric and thought disorders. A systematic review and meta-analysis.
2013
AbstractElevated number of parental Communication Deviance (CD) has been connected with psychiatric and thought disorders in their offspring. However, no earlier systematic efforts have been made to review this issue. The aim of this study was to survey the existing literature systematically and perform a meta-analysis of this association. A literature search for published and unpublished observational studies on the association of parental Communication Deviance with psychopathology in the offspring was conducted. Multiple electronic databases were searched (from 1960 to 2012) and the reference lists of the resulting publications were scanned. The findings were pooled using random effect m…
Early warning of systemic risk in global banking: eigen-pair R number for financial contagion and market price-based methods
2021
AbstractWe analyse systemic risk in the core global banking system using a new network-based spectral eigen-pair method, which treats network failure as a dynamical system stability problem. This is compared with market price-based Systemic Risk Indexes (SRIs), viz. Marginal Expected Shortfall (MES), Delta Conditional Value-at-Risk (Delta-CoVaR), and Conditional Capital Shortfall Measure of Systemic Risk (SRISK) in a cross-border setting. Unlike paradoxical market price based risk measures, which underestimate risk during periods of asset price booms, the eigen-pair method based on bilateral balance sheet data gives early-warning of instability in terms of the tipping point that is analogou…
"In der Mathematik ist ein Streit mit Sicherheit zu entscheiden". Perspektiven einer Soziologie der Mathematik
2000
Die Mathematik wird in diesem Aufsatz als ein empirisches Beispiel präsentiert, an dem sich die Voraussetzungen eines "rationalen Dissenses" exemplarisch untersuchen lassen. Denn im Gegensatz zu anderen epistemischen Kulturen gibt es in der Mathematik weder interpretative Flexibilität noch unentscheidbare Kontroversen. Auf der Basis einer medientheoretischen Perspektive und einer Feldstudie in einem internationalen Mathematikinstitut geht der Aufsatz der Frage nach, ob die Soziologie im Falle der Mathematik nicht auf eine prinzipielle Grenze stößt. In einem ersten Teil wird die These einer epistemischen Besonderheit der Mathematik präzisiert und in Auseinandersetzung mit zwei programmatisch…
Multi-Dimensional Acquisition, Representation, and Interaction of Cultural Heritage Tangible Assets
2018
The acquisition, digital representation and interaction of cultural heritage (CH) assets is of high interest for an accurate documentation of our cultural legacy. Detailed studies demand more information on the assets apart from the mere visual appearance or even shape of objects. In this regards, some research works can be found that combine shape with other kind of data, such as radiometric (e.g., IR, thermal radiation, etc.) or semantic information, leading to multi-Dimensional (mD) virtual objects. In this chapter, we review the state of the art of different techniques to deal with mD acquisition of CH tangible assets. We also discuss some representation (e.g., visual, sonic, etc.) and …
An experimental study on the effect of systemic functional linguistics applied through a genre-pedagogy approach to teaching writing
2016
Abstract In the tradition of teaching English as a second language, there has been an increased interest in how functional language descriptions and understandings of genres may be used as resources for making meaning. The present study investigates what impact writing instruction that draws upon systemic functional linguistics (SFL) applied through a genre-pedagogy approach has on students’ ability to write argumentative essays. This includes explicit grammar instruction inspired by SFL, as well as instruction on text structure. The study uses a mixed-methods approach, with a quasi-experiment followed up by quantitative and qualitative analyses of the collected material. Statistical analys…
Would a robot trust you? Developmental robotics model of trust and theory of mind
2019
Trust is a critical issue in human - robot interactions: as robotic systems gain complexity, it becomes crucial for them to be able to blend into our society by maximizing their acceptability and reliability. Various studies have examined how trust is attributed by people to robots, but fewer have investigated the opposite scenario, where a robot is the trustor and a human is the trustee. The ability for an agent to evaluate the trustworthiness of its sources of information is particularly useful in joint task situations where people and robots must collaborate to reach shared goals. We propose an artificial cognitive architecture based on the developmental robotics paradigm that can estima…
