The use of foraminifers as bioindicators of pollution in coastal and paralic environments has undergone a very fast development. Among various criteria, morphological anomalies are sometimes considered as pollution indicators. This paper presents a synthesis of the studies correlating foraminiferal assemblages and environmental concerns. Sediment cores retrieved along the northern coast of Sfax (Tunisia) are used to monitor the response of benthic foraminifera to modern pollution and environmental stress. Sediment samples were separated immediately after collection for benthic foraminifera analysis. Binocular microscope and the Scanning Electron Microscope (SEM) were carried out to identify the most significant, normal or deformed, specimens. All observations confirmed that foraminifera may be used as indicators of pollution after deconvoluting from natural impacts. The most sensitive foraminifera identified in the study area are Ammonia tepida, Ammonia beccarii, Elphidium crispum, Peneroplis pertususles Miliolidae, Peneroplis pertusus et Rosalina sp and Peneroplis planatus. The morphological study of benthic foraminifera from surface sediments attests for the pollution of the actual coast. This pollution is recorded in the benthic foraminifera tests mainly as shell deformations, chambers or streaks or abnormal colors. [less ▲]

Pour célébrer le bicentenaire de l’Université de Liège, nous souhaitons mettre en lumière le rayonnement international de l’un des premiers centres de recherche en Europe à s’être consacré aux « Commonwealth studies », le CEREP (Centre d’Enseignement et de Recherche en Etudes Postcoloniales). Fondé en 1968 par la Professeure Hena Maes-Jalinek sous l’acronyme CEREC (Centre d’Enseignement et de Recherche en Etudes du Commonwealth), le CEREP fut relancé en 2006 et met désormais en exergue la dimension postcoloniale, changeant ainsi son acronyme en CEREP. Nous comptons présenter, par ailleurs, quatre auteurs phares du paysage postcolonial qui se sont vus décerner l’insigne de Docteur honoris causa par l’ULg, à savoir, Salman Rushdie, Wilson Harris, Caryl Phillips et Paul Gilroy, pour lesquels le CEREP a joué un rôle important lors de leur accueil et présentation à l’Ulg.

L’empire byzantin se présente d’une certaine façon comme la traduction en grec de l’Empire romain. Fondée par Constantin en 324, mais achevée au VIe s., au temps de Justinien, Constantinople tâcha de s’imposer comme nouvelle Rome en terre grecque, puis, après la chute de l’Empire romain d’Occident, comme la seule version autorisée de l’Imperium Romanum. Rome était une ville bilingue. Constantinople se devait de l’être aussi. N’en déplaise à ceux qui avaient favorisé cette œuvre de translation, Constantinople n’était toutefois qu’une copie, une « belle infidèle », par rapport au prototype, qui reste unique. Il n’empêche que la romanité de Byzance est une évidence aux yeux de tous. Je tenterai de mesurer le degré de pénétration de la culture littéraire de langue latine à Constantinople à l’époque de l’empereur Justinien.

La présente communication se propose de retracer l’implantation progressive des cultures populaires comme objet de recherche à l’Université de Liège. Du colloque de Cerisy consacré à la paralittérature en 1967 à l’ouverture d’une mineure consacrée à la culture populaire en 2014, en passant par le développement des études en bande dessinée (avec le groupe ACME), en paralittérature, en littérature jeunesse et en jeu vidéo (avec le récent Liège GameLab), la prise en considération de ces œuvres souvent jugées illégitimes ou indignes comporte, aujourd’hui encore, d’importants enjeux scientifiques, politiques et idéologiques. À travers l’étude d’objets et de pratiques longtemps déclassés par les élites, c’est en effet la définition de l’art en tant qu’institution qui est questionnée. [less ▲]

Accounting conservatism is one of the oldest concepts in accounting, yet it is one of the most controversial topics nowadays. While there is little debate on the existence of accounting conservatism practices, the drivers and the implications of these accounting practices show considerable divergence between accounting researchers and standard setters (such as FASB/IASB). In their 2010 conceptual frameworks, the FASB and IASB removed conservatism from the qualitative characteristics of financial reporting. This decision has been the subject of considerable criticism from accounting researchers and has sparked a new debate on the mechanisms driving accounting conservatism as well as its benefits to market participants. This dissertation contributes to this new debate by providing three empirical essays on accounting conservatism. The first essay (Chapter 2) is part of the literature investigating the relation between accounting conservatism and corporate governance mechanisms. It documents that board attributes are important determinants of conservatism in financial reporting of French firms. The second essay (Chapter 3) extends the previous study and examines how the relation between board attributes and accounting conservatism varies across three European countries, namely, France, Germany and the UK. This essay emphasizes that the relationship between board characteristics and accounting conservatism is country dependent. Taken together, these two essays expand our understanding of how corporate governance mechanisms influence accounting quality. The third essay (Chapter 4) focuses rather on the informational benefits of accounting conservatism to financial market participants. This essay shows, in particular, that accounting conservatism improves the performance of analysts’ forecasts as well as the stock market liquidity. Overall, the main message to take away from this research is that accounting conservatism is closely related to corporate governance mechanisms and offers a powerful tool to provide verifiable information.

Since the 1950's, anthropogenic activities have increased nutrient river loads to European coastal areas. Subsequent implementation of nutrient reduction policies have led to considerably reduction of phosphorus (P) loads from the mid-1980's, while nitrogen (N) loads were maintained, inducing a P limitation of phytoplankton growth in many eutrophied coastal areas such as the Southern Bight f the North Sea (SBNS). When dissolved inorganic phosphorus (DIP) is limiting, most phytoplankton organisms are able to indirectly acquire P from dissolved organic P (DOP). We investigate the impact of DOP use on phytoplankton production and atmospheric fluxes of CO2 and dimethylsulfide (DMS) in the SBNS from 1951 to 2007 using an extended version of the RMIRO-BIOGAS model. This model includes a description of the ability of phytoplankton organisms to use DOP as a source of P. Results show that primary production can increase up to 30% due to DOP uptake under limiting DIP conditions. Consequently, simulated DMS emissions also increase proportionally while CO2 emissions to the atmosphere decrease, relative to the reference simulation without DOP uptake [less ▲]

La rééducation orthophonique des troubles de la voix est un vaste sujet. Mon intention n’est pas de vous exposer des séries d’exercices consacrées à la coordination pneumo-phonique, à la qualité de l’accolement cordal, au placement de la voix dans les résonateurs ou encore à la posture. De nombreux ouvrages orthophoniques expliquent ces pratiques et peuvent aisément enrichir vos connaissances sur le sujet. Après une brève introduction, j’ai choisi de vous présenter une démarche thérapeutique concrète qui repose sur une pratique basée sur les preuves (Evidence Based Practice, EBP). Autrement dit, comment un thérapeute de la voix peut-il implémenter dans sa pratique les bases de l’EBP afin d’assurer le meilleur traitement à son patient. Aussi, pour illustrer mon propos, j’ai opté pour une technique très discutée : la thérapie manuelle. Nous débattrons donc de l’efficacité thérapeutique sachant que les études de niveau 1A ou 1B sur le classement des niveaux de preuves sont rares dans le domaine de la vocologie. Ensuite, je ferai entendre une série de voix pré et post traitements. Cette étape, je l’espère, vous réconciliera avec le concept d’efficacité parfois si compliqué à démontrer. Je clôturerai la séance par une capsule vidéo illustrant des morceaux choisis de la thérapie vocale de trois patientes. Ces patientes et leur thérapeute, Catherine Jansen, ont aimablement accepté de livrer leur voix face caméra. [less ▲]

INTRODUCTION: Sessile serrated adenoma/polyp (SSA/p) is a precancerous lesion, mostly located in the right side of the colon (cecum, ascending and transverse colon). The difficulty is to visualize this lesion during colonoscopy because of its subtle appearance. MATERIAL AND METHOD: We compared proteomes of serrated polyps (SSA/p) and conventional adenomas using residual human formalin fixed paraffin embedded (FFPE) samples. FFPE-FASP method was applied on samples before label free proteomic analysis. Immunohistochemistry (IHC) characterisation of one candidate marker was performed for tissue validation on an independent set of samples including: conventional adenomas (low and high-grade dysplasia), serrated polyps (hyperplastic polyps, SSA/p and traditional serrated adenoma) and finally normal colon (taken at the margin of colorectal cancer (CRC) or of diverticular disease). RESULTS: Proteomics provided 765 proteins (out of 5992 proteins identified) significantly discriminating conventional adenomas from serrated lesions. We selected 53BP1 (Tumor suppressor p53-binding protein 1) among these for IHC validation, because of its tumor suppressor gene function and role as a mediator of DNA damage checkpoint. 53BP1 appeared significantly up-regulated in proteomes of low and high grade adenomas compared to these of normal tissue and SSA/p. 53BP1 IHC signal was located in the nucleus and the percentage of positive nucleus decreased in serrated polyps, especially in crypts and in the border epithelium, confirming part of the proteomic results. CONCLUSION: This study highlights potential marker proteins, including 53BP1 from which IHC signal was strongly decreased in some serrated polyps. The loss of 53BP1 has been associated with tumour progression and poor prognosis, while little is currently known about its involvement in precancerous CRC lesions. 53BP1 decrease of expression in the nucleus and therefore possible loss of function in some epithelial cells could reflect important changes occurring during dysplasia to neoplasia progression in serrated lesions.
