Visual Acuity and Contrast Sensitivity Depending from Keratoconus Apex Position
2017
Abstract Various studies have demonstrated that patients with keratoconus have significant loss of contrast sensitivity while its value varies in different studies. None of these studies has analysed reduced contrast sensitivity depending on the position of apex of corneal conus. Visual acuity and contrast sensitivity were evaluated for patients with keratoconus using the FrACT software. Contrast sensitivity was assessed at the following frequencies: 1, 3, 5, 7, 9, 11, 13, and 15 cycles per degree (cpd). Twenty-four eyes with keratoconus were analysed. Contrast sensitivity was significantly lower for patients with the apex at the centre compared with apex on the periphery both with (p = 0.0…
Mutations urbaines et logiques de localisation des emplois: le cas de la Communauté de l'agglomération dijonnaise (1990, 1999).
2004
The aim of this paper is to analyze the spatial changes in the Dijon urban area (COMADI) by studying in particular the new tendencies of localization of the high order producer services. Our results display a multicentric structure of the COMADI which exhibits several employment poles. Not only the economic composition of these poles differs between the central pole and the peripheral ones but this composition changes over the study period (1990-1999). New localization logics appear for the high order services : if the historical center remains specialized in financial activities, insurance and real estate (FIRE), the other producer services are more likely to be localized in the periphery.…
Using the centre-periphery framework to explore human-carnivore relations
2023
Unidad de excelencia María de Maeztu CEX2019-000940-M Living alongside carnivores can incur both costs and benefits on people's lifeways. While positive outcomes of carnivore presence can foster coexistence, negative relations with carnivores can trigger carnivores' killing and undermine their conservation. In response to this, conservation efforts increasingly focus on promoting positive human-carnivore relations, most often through improvements in the flow of economic benefits from carnivores to local communities. However, there is a question mark over the effectiveness and potential consequences of market-based instruments for carnivore conservation. To understand the opportunities and p…
Els verbs de percepció visual en català: classificació semàntica i distribució en gèneres escrits
2022
This work focuses on the study of the meanings conveyed by two visual perception verbs (mirar and veure) in Central Catalan within the theoretical framework of cognitive semantics. Our objective is twofold: (i) to analyze and describe them in order to establish metaphorical and metonymic semantic projections; and (ii) to determine the intralinguistic distribution of the non-prototypical meanings of these verbs. We have analyzed examples extracted from dictionaries (mostly DIEC2) and 1.750 forms picked out from the literary narrative and press texts of the Corpus textual informatitzat de la llengua catalana (CTILC). By analyzing these examples and the context in which they appear, we establi…
Defectivitat morfològica i variació sintàctica
2021
This paper discusses a case of parametric variation between Catalan and Spanish that concerns the fronting possibilities within the CP domain (the so-called ÇLeft PeripheryÈ). In particular, attention is paid to Catalan’s weak left peripheral activity, which prevents it from generating sentences that involve a Çmild focalizationÈ pattern very common in Spanish (e.g., «Mucha tontería dice el Gobierno» vs. *«Molta ximpleria diuel Govern»), first noted by Torrego (1980) and further explored by Uriagereka (1988). Interestingly, the same behavior is observed in the v*P domain, which accounts for the fact that VSO sentences (generated through movement of the subject to a specifier position, as Or…
Un tipus especial d'oracions interrogatives: les interrogatives escindides
2014
This paper deals with the properties of interrogative sentences with a split constituent (or split interrogatives) in Catalan and Spanish. We compare split interrogatives with Wh-questions, yes/no questions, different kinds of confirmatory questions and clitic left dislocation constructions. Split interrogatives show a very clear-cut syntactic and phonological distinction between those constituents to be interpreted as shared or old information (theme) and the constituent which receives the focus of the sentence. Following recent theoretical work on the left periphery of the sentence, we propose that the Ground Phrase projection (placed below ForceP) is especially relevant in split interrog…
Europa wielu prędkości i kwestia Europy Wschodniej. Ujęcie centro-peryferyjne
2021
Artykuł przedstawia zagadnienie niepewności wynikającej z ekonomicznej nierówności państw członkowskich w Unii Europejskiej. Autor opiera się na perspektywie centro-peryferyjnej i stawia tezę, że nierówność potencjału państw i regionów w UE wynika ze zróżnicowania historycznego o charakterze społeczno-gospodarczym. Współczesny dyskurs wokół koncepcji „Europy wielu prędkości” jest próbą nadania kwestii centro-peryferyjnej w Europie konkretnych ram politycznych i instytucjonalnych. Koncepcja ta jest krytykowana w nowych krajach członkowskich UE, które obawiają się peryferyzacji i pozostają zależne od europejskiej polityki spójności. W analizie wykorzystano także ustalenia z zakresu studiów na…
Verb-Second and (micro)-variation in two Rhaeto-Romance varieties of Northern Italy.
2018
Rhaeto-Romance varieties are the only present-day Romance varieties which exhibit the Verb Second constraint (Benincà 1994, Poletto 2002, Salvi 2010). In this chapter we examine two properties typically ascribed to the Verb Second phenomenon, subject-finite verb inversion and restrictions on the co-occurrence of multiple constituents in the sentence-initial position, in two Rhaeto-Romance varieties spoken in South Tyrol (Province of Bolzano, Northern Italy). We demonstrate that both varieties behave like Verb-Second languages as far as both phenomena are concerned, but exhibit a specific Verb-Second system governed by the interplay between syntactic and discourse constraints which differs f…
Wh-Relative Clauses and Left Periphery from Latin to some Romance Languages
2011
The paper is organized as follows: after an introduction of the issue we will examine, in the first section we shall discuss the theory of the antisymmetry of syntax as specifically concerns relative clauses, evidencing also problems linked to the application of this theory to the syntax of relative clauses in Latin and in other Indo-European languages; the second section will present our first attempt at some analysis of the left periphery of the Proto-Indo-European sentence; in the third section we shall discuss the categorial status of the relative pronoun in Latin and we shall produce a model of the left periphery of the Latin subordinate clause, supplying examples taken from literary a…
Structuration du territoire bourguignon : de l'île à l'isthme
2006
Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
