Constructing Languages to Explore Theoretical Principles

The construction of languages has always been related to linguistics. Most of these initiatives address real scientific questions but from a non-academic point of view. The fact that Ferdinand de Saussure's own brother, René de Saussure, wrote a theoretical essay on the construction of the Esperanto word (de Saussure 1914) is an amusing illustration of this. In this paper, we propose a method inspired by experimental archaeology. The experiment consists in trying to obtain an artifact similar to the one observed using this or that construction method. An equivalent approach in linguistics would be the generation of linguistic systems based on explicitly formulated principles. Trying to generate similar systems pushes the linguist to explicitly define the principles that are needed and to explore all their consequences. In this context, we show that the use of notions induced by the observation of natural languages leads to a certain degree of circularity and that it is therefore more interesting to explore a priori principles based on very general assumptions

The Romance plural isogloss and linguistic change: A comparative study of Romance nouns

International audienceRomance nouns show a well-known morphological isogloss. There are two groups of languages: those pluralizing by suffixing -s (such as Spanish), and those pluralizing by changing the quality of the final vowel (such as Italian). In this paper, I propose an explanation of this isogloss. More precisely, I argue that the cross-linguistic diversity within Romance depends on morpho-phonological parameters on the structure of the noun. These parameters consist of language-particular restrictions on the form of the (nominal) roots and the exponents of gender and number

A Classless Analysis of Italian Nouns and their Theme-Vowel Alternations

The decompositional, non-lexicalist, approach to word-structure and the theory of roots have proven highly rewarding. One grey area, however, comes from Romance since, rather than roots, the word structure primitive appears to be the stem: root + ‘stem-formative/theme vowel’. Regardless, there have been perspicacious decompositional accounts of Italian, however these are still marred by the large number of morphological/item-specific irregularities, motivating arbitrary noun classes. Additionally, there are roots that do not inflect: consonant-final and vowel-final forms when these are oxytonic or loanwords. Given these irregularities, previous analyses in Italian have included the use of lexical exceptions and class features. We challenge the use of class features in generating the attested patterns (and their exceptions). Instead, we propose a new categorisation of root-shapes, which, when combined with the exponents of nominal inflection, produce the correct surface pairings, as well as the non-alternating forms. In our analysis, there is no diacritic or special marking of lexical exceptions, all forms inflect regularly in accordance to their phonological shape. This requires the innovation of one new mechanism (Inhibition), but we back it up by showing that it leads to an unexpected beneficial prediction that solves a long-standing problem associated with Raddoppiamento Sintattico (RS)

Identification of Novel Dermoscopic Patterns for “Featureless Melanoma”: Clinical-Pathological Correlation

Introduction:Diagnosis of melanoma can be sometimes very difficult because of its phenotypic and histological heterogeneity.Difficult-to-diagnose melanoma can be represented by mucosal melanoma, pink lesions, amelanotic melanoma (amelanotic lentigo maligna, amelanotic acral melanoma, desmoplastic melanoma), melanoma arising on sun-damaged facial skin, and “featureless melanoma”.Objective:The aim of the study was to improve the identification of featureless melanoma (scoring 0-2 according to 7-point-checklist)describing the variegated dermoscopical features and their histo-pathological correlation.Methods:Study samples included all melanomas excised based on clinical and/or dermoscopic findings in the period between January 2017 and April 2021.Before excisional biopsy, all lesions were recorded by means of digital dermoscopy at the department of Dermatology.Only lesions with a diagnosis of melanoma and a high quality of dermoscopic images were included in this study. After clinical and dermoscopic evaluation of 7-point checklist score, single dermoscopic and histological features were considered for lesions with a score of 2 or lower and a diagnosis of melanoma (corresponding to dermoscopic featureless melanoma).Results:A total of 691 melanomas fulfilled inclusion criteria and were retrieved from the database. The 7-point checklist evaluation identified 19 “negative-featureless” melanoma.The 100% of the lesions with score 1 showed a globular pattern. Conlusions:Dermoscopy is still the best diagnostic method for melanoma. The 7-point checklist provides a simplification of standard pattern analysis because of the algorithm based on a scoring system and the lower number of features to recognize. In the daily practice it is more comfortable for many clinicians to keep in mind a list of principles that may help in the decision

MORFEO enters final design phase

MORFEO (Multi-conjugate adaptive Optics Relay For ELT Observations, formerly MAORY), the MCAO system for the ELT, will provide diffraction-limited optical quality to the large field camera MICADO. MORFEO has officially passed the Preliminary Design Review and it is entering the final design phase. We present the current status of the project, with a focus on the adaptive optics system aspects and expected milestones during the next project phase

Forme phonologique, exposants morphologiques et structures nominales: étude comparée de l'italien, du bosnien et du somali

DNAL’objectif de cette thèse est de caractériser la relation entre la substance phonologique et les propriétés morpho-syntaxiques lors du processus de formation des mots. Plus particulièrement, il est question de comprendre comment le signifiant est organisé, à l’intérieur d’un système morphologique donné, par rapport aux propriétés morpho-syntaxiques exprimées par ce même système. Nous allons donc explorer la façon dont trois langues non apparentées - l’italien, le bosnien et le somali - organisent leurs systèmes nominaux. Nous allons proposer une forme phonologique pour chacune des propriétés morpho-syntaxiques retrouvées dans les systèmes nominaux des trois langues mentionnées. Plus précisément, notre hypothèse principale prévoit que chaque catégorie ne peut être associée qu’à une seule séquence phonologique donnée
