Le vague - De l’usage évaluatif d’un terme en français et en allemand à la reconstruction d’un concept

The aim of this research is to outline the concept of VAGUENESS in ordinary discourse by analyzing the uses of the adjectives vague in French and vage in German employed by speakers encountering an expression or an utterance they judge vague. The data consist of newspaper articles containing value judgments like “c’est vague” (it’s vague), “réponse vague” (vague answer), “expression vague” (vague expression), etc. By means of a qualitative and inductive method, this study acknowledges a special interest in ordinary speakers’ metalinguistic evaluative statements and attempts to determine the different meanings and functions attached to those evaluating terms. It will be shown that the use of the words vague/vage may point out a lack of information, a high degree of abstractness or a problem of multi-referentiality of the expression being judged; it is also possible to make assumptions about the pragmatic functions those judgments are fulfilling, such as, for instance, disqualifying one’s opponent, a common strategy in political debate situations. Inspired by Folk Linguistic studies, this thesis distinguishes itself from logical- and philosophical approaches as well as from the methodology of some pragmatic researches about vagueness and, in so doing, endeavors to contribute to a larger definition of the concept.L’objectif de cette recherche est de cerner le concept du VAGUE dans le discours quotidien à travers l’emploi des adjectifs vague en français et vage en allemand tels qu’ils sont utilisés par des locuteurs ordinaires lors de l’appréciation d’un terme ou d’un énoncé auxquels ils ont été confrontés. Le corpus est constitué d’extraits d’articles de presse francophone et germanophone contenant les jugements de valeur « c’est vague », « réponse vague », « expression vague », etc. À l’aide d’une méthode qualitative et inductive, partant de jugements singuliers, ce travail laisse la parole au locuteur ordinaire et essaie de relever les différents sens ainsi que les diverses fonctions que peuvent avoir les termes vague/vage dans le langage courant. Ainsi, on montre que l’emploi des mots vague/vage peut non seulement signaler entre autres un manque d’informations, un degré élevé d’abstraction ou un problème de multi-référentialité de l’expression jugée mais également servir à disqualifier l’adversaire, fonction qui semble récurrente en situation de débat politique. Cette recherche se démarque par sa méthode, inspirée de travaux relevant de la Folk Linguistics (linguistique populaire), d’approches logico-philosophiques et de certaines études pragmatiques sur le VAGUE, mais elle vise également à compléter les catégories et les définitions existantes dans cette littérature à propos de ce phénomène. Il s’agit d’un travail conceptuel qui tient à apporter de nouvelles connaissances dans le champ des études menées sur le concept du VAGUE

Influence of ionospheric perturbations in GPS time and frequency transfer

The stability of GPS time and frequency transfer is limited by the fact that GPS signals travel through the ionosphere. In high precision geodetic time transfer (i.e. based on precise modeling of code and carrier phase GPS data), the so-called ionosphere-free combination of the code and carrier phase measurements made on the two frequencies is used to remove the first-order ionospheric effect. In this paper, we investigate the impact of residual second- and third-order ionospheric effects on geodetic time transfer solutions i.e. remote atomic clock comparisons based on GPS measurements, using the ATOMIUM software developed at the Royal Observatory of Belgium (ROB). The impact of third-order ionospheric effects was shown to be negligible, while for second-order effects, the tests performed on different time links and at different epochs show a small impact of the order of some picoseconds, on a quiet day, and up to more than 10 picoseconds in case of high ionospheric activity. The geomagnetic storm of the 30th October 2003 is used to illustrate how space weather products are relevant to understand perturbations in geodetic time and frequency transfer.Comment: 25 pages, 10 eps figures, 1 table, accepted in Journal of Advances in Space Research, Special Issue "Recent advances in space weather monitoring, modelling and forecasting

Inégalité(s) dans le discours de la presse française :usages discursifs et dimensions sémantiques d’un mot

L’inégalité est une thématique sociale, abordée de façon récurrente dans les médias. Appliquant une approche de « sémantique discursive », nous examinerons l’usage d’inégalité(s) dans le discours de presse en circonscrivant les principales dimensions sémantiques du nom à travers ses fonctionnements préférentiels en cotexte, étroit ou élargi. Après quelques questionnements sémantico-référentiels autour du mot, l’étude du corpus – constitué d’articles issus des journaux Le Monde, Libération et Le Figaro – montrera qu’inégalité(s) fonctionne, à la fois, comme un lieu d’observation, d’évaluation et de revendication. L’analyse conduit également à penser que l’usage partagé et consensuel du segment lutte contre les inégalités dans le corpus fait apparaître une forme de « langue de bois ».Inequality is a common social theme which arises regularly in the press. Using a semantic-discursive approach, we will examine the use of the word inégalité(s) (inequality(s)) in media discourse with the aim to circumscribe the main semantic dimensions of the word through its functioning in co-text. After some semantical and referential considerations, data analysis will show that inégalité(s) functions as lieu of observation, evaluation and political claims. The corpus contains newspaper articles from Le Monde, Libération and Le Figaro. The data analysis also lead to the assumption that the shared and consensual use of the segment lutte contre les inégalités (fight against inequality) shows features of some sort of doublespeak (“langue de bois”)

The LatMix summer campaign : submesoscale stirring in the upper ocean

The definitive version was published in Bulletin of the American Meteorological Society 96 (2015): 1257–1279, doi:10.1175/BAMS-D-14-00015.1.Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for smaller-scale stirring processes. Here, the authors describe a major oceanographic field experiment aimed at observing and understanding the processes responsible for stirring at scales of 0.1–10 km. Stirring processes of varying intensity were studied in the Sargasso Sea eddy field approximately 250 km southeast of Cape Hatteras. Lateral variability of water-mass properties, the distribution of microscale turbulence, and the evolution of several patches of inert dye were studied with an array of shipboard, autonomous, and airborne instruments. Observations were made at two sites, characterized by weak and moderate background mesoscale straining, to contrast different regimes of lateral stirring. Analyses to date suggest that, in both cases, the lateral dispersion of natural and deliberately released tracers was O(1) m2 s–1 as found elsewhere, which is faster than might be expected from traditional shear dispersion by persistent mesoscale flow and linear internal waves. These findings point to the possible importance of kilometer-scale stirring by submesoscale eddies and nonlinear internal-wave processes or the need to modify the traditional shear-dispersion paradigm to include higher-order effects. A unique aspect of the Scalable Lateral Mixing and Coherent Turbulence (LatMix) field experiment is the combination of direct measurements of dye dispersion with the concurrent multiscale hydrographic and turbulence observations, enabling evaluation of the underlying mechanisms responsible for the observed dispersion at a new level.The bulk of this work was funded under the Scalable Lateral Mixing and Coherent Turbulence Departmental Research Initiative and the Physical Oceanography Program.

The Rest-Frame Optical Luminosity Function of Cluster Galaxies at z<0.8 and the Assembly of the Cluster Red Sequence

We present the rest-frame optical luminosity function (LF) of red sequence galaxies in 16 clusters at 0.4<z<0.8 drawn from the ESO Distant Cluster Survey (EDisCS). We compare our clusters to an analogous sample from the Sloan Digital Sky Survey (SDSS) and match the EDisCS clusters to their most likely descendants. We measure all LFs down to M M* + (2.5 - 3.5). At z<0.8, the bright end of the LF is consistent with passive evolution but there is a significant build-up of the faint end of the red sequence towards lower redshift. There is a weak dependence of the LF on cluster velocity dispersion for EDisCS but no such dependence for the SDSS clusters. We find tentative evidence that red sequence galaxies brighter than a threshold magnitude are already in place, and that this threshold evolves to fainter magnitudes toward lower redshifts. We compare the EDisCS LFs with the LF of co-eval red sequence galaxies in the field and find that the bright end of the LFs agree. However, relative to the number of bright red galaxies, the field has more faint red galaxies than clusters at 0.6<z<0.8 but fewer at 0.4<z<0.6, implying differential evolution. We compare the total light in the EDisCS cluster red sequences to the total red sequence light in our SDSS cluster sample. Clusters at 0.4<z<0.8 must increase their luminosity on the red sequence (and therefore stellar mass in red galaxies) by a factor of 1-3 by z=0. The necessary processes that add mass to the red sequence in clusters predict local clusters that are over-luminous as compared to those observed in the SDSS. The predicted cluster luminosities can be reconciled with observed local cluster luminosities by combining multiple previously known effects.Comment: Accepted for publication in the Astrophysical Journal. 36 pages, 16 figures, 10 table

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

Background: The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes. Methods: LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January–December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien–Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141). Results: A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively. Conclusions: This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives

The impact of corporate volunteering on CSR image: a consumer perspective

Received: 29 June 2013 / Accepted: 15 January 2014Abstract Corporate volunteering (CV) is known to be an effective employee engagement initiative. However, despite the prominence of corporate social responsibility (CSR) in academia and practice, research is yet to investigate whether and how CV may influence consumer perceptions of CSR image and subsequent consumer behaviour. Data collected using an online survey in Australia show perceived familiarity with a company’s CV programme to positively impact CSR image and firm image, partially mediated by others-centred attributions. CSR image, in turn, strengthens affective and cognitive loyalty as well as word-of-mouth. Further analysis reveals the moderating effect of perceived leveraging of the corporate volunteering programme, customer status and the value individuals place on CSR. The paper concludes with theoretical and managerial implications, as well as an agenda for future research.Carolin Plewa, Jodie Conduit, Pascale G. Quester, Claire Johnso

Seeing Polycentrically: Examining Governance Situations Using a Polycentricity Lens

Because many types of governance can be polycentric, an observer faces a challenge in trying to identify and understand polycentric governance in actual settings. This chapter adopts the perspective of thinking about polycentricity as a lens through which to view governance situations. We take an inquiry approach, considering how one might determine whether and in what ways a given governance situation demonstrates the characteristics of polycentric governance. We proceed through a series of questions an observer could pose as part of 'seeing polycentrically', i.e., looking at the aspects and dimensions of polycentric governance introduced in Stephan, Marshall, and McGinnis as a way of building an understanding of a governance situation. We attempt to describe why these queries are important and how posing and answering these questions helps in examining and understanding the situation. We close the chapter by considering the challenges of assessing the operation of polycentric governance arrangements
