    Tracing thick and thin concepts through corpora

    Philosophers and linguists currently lack the means to reliably identify evaluative concepts and measure their evaluative intensity. Using a corpus-based approach, we present a new method to distinguish evaluatively thick and thin adjectives like ‘courageous’ and ‘awful’ from descriptive adjectives like ‘narrow,’ and from value-associated adjectives like ‘sunny.’ Our study suggests that the modifiers ‘truly’ and ‘really’ frequently highlight the evaluative dimension of thick and thin adjectives, allowing for them to be uniquely classified. Based on these results, we believe our operationalization may pave the way for a more quantitative approach to the study of thick and thin concepts

    Personality Dysfunction Manifest in Words : Understanding Personality Pathology Using Computational Language Analysis

    Get PDF
    Personality disorders (PDs) are some of the most prevalent and high-risk mental health conditions, and yet remain poorly understood. Today, the development of new technologies means that there are advanced tools that can be used to improve our understanding and treatment of PD. One promising tool – indeed, the focus of this thesis – is computational language analysis. By looking at patterns in how people with personality pathology use words, it is possible to gain access into their constellation of thinking, feelings, and behaviours. To date, however, there has been little research at the intersection of verbal behaviour and personality pathology. Accordingly, the central goal of this thesis is to demonstrate how PD can be better understood through the analysis of natural language. This thesis presents three research articles, comprising four empirical studies, that each leverage computational language analysis to better understand personality pathology. Each paper focuses on a distinct core feature of PD, while incorporating language analysis methods: Paper 1 (Study 1) focuses on interpersonal dysfunction; Paper 2 (Studies 2 and 3) focuses on emotion dysregulation; and Paper 3 (Study 4) focuses on behavioural dysregulation (i.e., engagement in suicidality and deliberate self-harm). Findings from this research have generated better understanding of fundamental features of PD, including insight into characterising dimensions of social dysfunction (Paper 1), maladaptive emotion processes that may contribute to emotion dysregulation (Paper 2), and psychosocial dynamics relating to suicidality and deliberate self-harm (Paper 3) in PD. Such theoretical knowledge subsequently has important implications for clinical practice, particularly regarding the potential to inform psychological therapy. More broadly, this research highlights how language can provide implicit and unobtrusive insight into the personality and psychological processes that underlie personality pathology at a large-scale, using an individualised, naturalistic approach

    The socratic dialogue as a ritual of emotional purification

    Abstract In the present paper, the role that emotions play in Socratic self-care, as it can be reconstructed from Plato's dialogues, is investigated and explored. In highlighting the fundamental role that emotions play in such a care, which is not mere repair of a fault (reparative care), but an active and constant attending to self- and others' improvement, it is emphasized how the Socratic care that is enacted in the Selected Dialogues exhibits marked religious qualities, which make Socrates a kind of priestly and demonic figure, as the reader can infer in particular from the two chapters devoted to the Critique and the Apology, respectively. The intent underlying this focus on the religious and especially initiatory aspects of Socratic care in the Platonic dialogues is, as explained at the beginning of the introduction to this work, to deepen the link between the emotional aspect of self-care, explored in depth by Professor L. Napolitano, and my personal interest in the relationship between philosophy and religion. In the present work this link has been found in the theme of 'aporia; this is interpreted in the introduction and in the following chapters as ritual death, that is, as an 'experience in which the initiate (in this case Socrates' interlocutor) witnesses his own death, that is, the disappearance of the firm attachment to his unreflective opinions. It follows that 'aporia is a positive element of self-care, since this ritual death makes it possible, if it is accepted and not rejected, to get rid of those obstacles from within that prevent one from looking forward to one's own improvement and the pursuit of happiness. Aporia is not only a logical impasse, but also an emotionally very dense moment; it therefore holds together the two fundamental components of this work, the focus on emotions in the Socratic dialogue and the focus on the initiatory aspects with which Plato cloaks this dialogue. Plato alludes to these initiatory aspects from time to time in the selected dialogues by appropriating now from Coribantism (Euthydemus), now from Orphism (Phaedo), now even from the rituals of transition from one age to another (the ephebia, as in the case of the Alcibiades); all these disparate experiences have in common the idea of a ritual death, a liminal phase between one life (the one about to leave) and the new one (about to embark on). In the Socratic dialogue enacted in Plato's works, precisely this initiatory death (the aporia) is II achieved; if the interlocutor accepts it, he or she will progress on the path of self care; if he or she is afraid or annoyed by it, he or she will derive no benefit. The introduction outlines the assumptions on which the following analysis are based: the first is the ritual and initiatory nature of refutation and the characterization of aporia as an emotionally connoted moment; the second, based on the analysis of the first book of the Republic, is the relational nature of caring and thus of the good that caring/caretaking pursues; therefore, one who cares for others necessarily also cares for himself. The intertwining of the ritual and emotional aspects, as well as the communal and relational nature of the good pursued by Socratic caring, is explored throughout the introduction and, more importantly, eight chapters, devoted to Euthydemus, Charmides, Alcibiades I, Lysis, Euthyphro, Apology, Critique, and Phaedo, respectively. In the introduction to the thesis, the reason for the choice of these dialogues is explained and what are the relationships between them in this work. In the conclusion, the scientific and especially moral reasons for the importance of emphasizing the role of emotions in Plato's Socrates and the ritual aspects of it are made clea

    Multidisciplinary perspectives on Artificial Intelligence and the law

    Get PDF
    This open access book presents an interdisciplinary, multi-authored, edited collection of chapters on Artificial Intelligence (‘AI’) and the Law. AI technology has come to play a central role in the modern data economy. Through a combination of increased computing power, the growing availability of data and the advancement of algorithms, AI has now become an umbrella term for some of the most transformational technological breakthroughs of this age. The importance of AI stems from both the opportunities that it offers and the challenges that it entails. While AI applications hold the promise of economic growth and efficiency gains, they also create significant risks and uncertainty. The potential and perils of AI have thus come to dominate modern discussions of technology and ethics – and although AI was initially allowed to largely develop without guidelines or rules, few would deny that the law is set to play a fundamental role in shaping the future of AI. As the debate over AI is far from over, the need for rigorous analysis has never been greater. This book thus brings together contributors from different fields and backgrounds to explore how the law might provide answers to some of the most pressing questions raised by AI. An outcome of the Católica Research Centre for the Future of Law and its interdisciplinary working group on Law and Artificial Intelligence, it includes contributions by leading scholars in the fields of technology, ethics and the law.info:eu-repo/semantics/publishedVersio

    Safe passage for attachment systems:Can attachment security at international schools be measured, and is it at risk?

    Get PDF
    Relocations challenge attachment networks. Regardless of whether a person moves or is moved away from, relocation produces separation and loss. When such losses are repeatedly experienced without being adequately processed, a defensive shutting down of the attachment system could result, particularly when such experiences occur during or across the developmental years. At schools with substantial turnover, this possibility could be shaping youth in ways that compromise attachment security and young people’s willingness or ability to develop and maintain deep long-term relationships. Given the well-documented associations between attachment security, social support, and long-term physical and mental health, the hypothesis that mobility could erode attachment and relational health warrants exploration. International schools are logical settings to test such a hypothesis, given their frequently high turnover without confounding factors (e.g. war trauma or refugee experiences). In addition, repeated experiences of separation and loss in international school settings would seem likely to create mental associations for the young people involved regarding how they and others tend to respond to such situations in such settings, raising the possibility that people at such schools, or even the school itself, could collectively be represented as an attachment figure. Questions like these have received scant attention in the literature. They warrant consideration because of their potential to shape young people’s most general convictions regarding attachment, which could, in turn, have implications for young people’s ability to experience meaning in their lives

    What effect does short term Study Abroad (SA) have on learners’ vocabulary knowledge?

    This thesis describes a study which tracks longitudinal changes in vocabularyknowledge during a short-term Study Abroad (SA) experience. A test ofproductive vocabulary knowledge, Lex30 (Meara & Fitzpatrick, 2000),requiring the production of word association responses, is used to elicit vocabulary from 38 Japanese L1 learners of English at four test times at equal intervals before and after an SA experience. The study starts by investigating whether there are changes in both the total number of words and in the number of less frequently occurring words produced by SA participants. Three additional ways of measuring the development of lexical knowledge over time are then proposed. The first examines changes in the ability of participants of different proficiency levels in producing collocates in response to Lex30 cue words. The second tracks changes in spelling accuracy to measure if improvements take place over time. The third analysis uses an online measuring instrument (Wmatrix; Rayson, 2009) to explore if there are any changes in the mastery of specific semantic domains. The results show that there is significant growth in the productive use of less frequent vocabulary knowledge during the SA period. There is also an increase in collocation production with lower proficiency participants and evidence of some improvement in the way certain vocabulary items are spelled. The tendency for SA learners to produce more words from semantic groups related to SA experiences is also demonstrated. Post-SA tests show that while some knowledge attrition occurs it does not decline to pre-SA levels. The studyshows how short-term SA programmes can be evaluated using a word association test, contributing to a better understanding of how vocabularydevelops during intensive language learning experiences. It also demonstrates the gradual shift of productive vocabulary knowledge from partial word knowledge to a more complete state of productive mastery

    Clinical and imaging biomarkers of audiovestibular function in infratentorial superficial siderosis

    Disabling hearing loss is known to affect over 400 million people worldwide while the lifetime prevalence of dizziness can be as high as 40%. Rare causes for hearing and balance impairment are often understudied. Infratentorial (classical) superficial siderosis (iSS) is a rare but sometimes disabling complex neurological condition most often associated with hearing and balance impairment, and myelopathy. Olfactory loss has been reported but not yet systematically studied. iSS results from a chronic low-grade and low volume bleeding into the cerebrospinal fluid and the deposition of iron-degradation products (predominantly haemosiderin) in the subpial layers of the central nervous system, with predilection for the cerebellum and the vestibulocochlear nerves. Magnetic resonance imaging (MRI) allows haemosiderin to be visualised in-vivo and is the mainstream diagnostic modality. Due to the assumed rarity of iSS (prevalence of 0.03-0.14%), our research opportunities are limited. Few dedicated studies describe iSS-related audiovestibular (AV) findings, often limited to case-series, with mixed findings. There is currently no robust evidence that the radiological haemosiderin appearances correlate with the objective clinical tests. This project focuses on phenotyping the AV function in iSS and identifies predominantly retrocochlear hearing loss with features suggestive of central auditory dysfunction, and mixed vestibular (predominantly cerebellar) dysfunction. This work introduces and validates an imaging rating scale aiming to capture the anatomical extent of haemosiderin deposits visualised on MRI in a standardised and reproducible way. The scale demonstrates excellent reliability and good validity, with the scores correlating with hearing thresholds. This project estimates the prevalence of MRI-defined iSS in a large UK Biobank sample, similar to other rare neurootological disorders. Using patient/self-report measures, this work captures markedly low health-states of individuals with iSS and identifies possible iSS-specific auditory characteristics. Finally, the work identifies high prevalence of olfactory dysfunction in individuals with iSS

    Comparing the production of a formula with the development of L2 competence

    Get PDF
    This pilot study investigates the production of a formula with the development of L2 competence over proficiency levels of a spoken learner corpus. The results show that the formula in beginner production data is likely being recalled holistically from learners’ phonological memory rather than generated online, identifiable by virtue of its fluent production in absence of any other surface structure evidence of the formula’s syntactic properties. As learners’ L2 competence increases, the formula becomes sensitive to modifications which show structural conformity at each proficiency level. The transparency between the formula’s modification and learners’ corresponding L2 surface structure realisations suggest that it is the independent development of L2 competence which integrates the formula into compositional language, and ultimately drives the SLA process forward
