First person – Viorica Raluca Contu
No full textABSTRACT
First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Viorica Raluca Contu is co-first author on ‘Lysosomal targeting of SIDT2 via multiple YxxΦ motifs is required for SIDT2 function in the process of RNautophagy’, published in Journal of Cell Science. Viorica is a PhD student at the National Institute of Neuroscience, NCNP, Japan, investigating intracellular RNA degradation by the lysosomes and its possible involvements in disease pathogenesis and treatment.</jats:p
A contribution to the understanding of how decentralised and competitive markets work
No full textL?idée de la concurrence « pure » est paradoxalement incarnée, dans l'analyse économique, par un contexte de marché très centralisé, régi par un commissaire priseur. A tel point que l?on peut légitimement se demander où est la concurrence et où est la liberté d'action des agents économiques dans cette représentation. L?objet de la thèse est d?étudier une représentation alternative de la concurrence « pure », qui fasse sa place à la liberté de fixer les prix des offreurs et au pouvoir (concurrentiel) des demandeurs de choisir leur offre. On se demande alors simplement : comment fonctionne un tel marché décentralisé et concurrentiel. L?énigme se situe au confluent de deux courants. Le premier est de nature analytique : sur ce marché il n?existe pas d?équilibre de Nash en stratégies pures. Le deuxième est de nature pratique : les résultats des expérimentations réalisées depuis une quarantaine d'années ont montré que nul ne saurait prédire le comportement de tels marchés. Nous contribuons à ce débat en montrant, à partir d?une étude expérimentale, que la concurrence, à elle seule, ne conduit pas en général le marché vers l?issue « concurrentielle ». Au passage, nous montrons même que, contrairement à ce qu'on pense habituellement en économie, lorsque l?on parvient à ce résultat, ce n'est pas la rationalité des agents qui conduit le marché vers cette issue, mais plutôt leur manque de rationalité. Dans ce contexte de marché marqué par l?absence d?équilibre, c?est moins la structure du jeu que les conduites effectivement adoptées par les agents qui en déterminent l?issue. Se pose ainsi la question de la sélection des comportements adéquats à ce contexte « d?absence ». A l?aide de simulations informatiques, nous montrons que la concurrence, envisagée cette fois-ci à un méta-niveau mène à un état final stable… mais très différent de celui que l'on attendait : le marché peut se trouver, à la fin d'un processus de sélection dans un état très proche du cartel.Economics paradoxically attribute “pure” competition to an extremely centralised market governed by an auctioneer. Therefore, one can legitimately wonder then where “competition” and economic agents? freedom actually is under this representation. This thesis? object is the study of an alternative representation of « pure » competition in which suppliers are free to fix prices and bidders can competitively choose their outputs. We wonder how this decentralised and competitive market works. The enigma that we study is situated at the confluence of two currents. The first one is of analytical nature: there exists no Nash equilibrium (under pure strategies hypothesis) for the market under study. The second one is of “practical” nature: the results of experiments carried over for the last 40 years show that no one can predict how these markets behave. We contribute to this debate by showing, experimentally, that competition in itself does not automatically lead markets towards the competitive issue. Furthermore, we show that, contrary to economics? “common knowledge”, when this issue is actually reached, it may be so due to subjects? lack of rationality. In this market, it is agents? behaviour and to a lesser extent, game structure, which will determine the final issue observed. One may then wonder how selection will operate amongst behaviours which are appropriate for this market context. A series of informatic simulations show that competition, considered this time at a meta-level will lead markets towards a stable state… but a state which is completely the opposite of what would have been expected. At the end of a selection process markets can find themselves at cartel-like state
The Return of the Author
No full textThis article will discuss Întoarcerea Autorului (The Return of the Author), published for the first time in Communist Romania in 1981, and, after 1990, in France and the United States, republished in post-Communist Romania in 1993, 2005, and 2013, the fourth edition. The article will try to follow the historical and cultural background for the volume and its subsequent editions to answer the question who is the author of the “return of the author”? I will point to the implicit and explicit dialogue of the 1981 book with other books dealing with the same topic and perceive their coincidences – with reference to Sean Burke, Dominique Maingueneau, Antoine Compagnon and Valentine Cunningham. I will focus on one of the most important and daring ideas of this book (which can be retraced afterwards, in Reading after Theory by Cunningham): those critics who proclaim the death of the author have proved to be the most authorial and authoritarian of all. Within the broader context of author studies, I will outline the characteristic features of the 1981 book and the actuality of Simion’s critical position

Pandemicfridge: Collaboration at a Distance
No full textThe Covid-19 pandemic affected all aspects of contemporary life, from how we work to how we shop, travel, and eat. Previously banal activities such as going to the grocery store became challenging and anxiety-inducing, with a new level of danger associated with leaving one’s home. To document and respond to this global experience, Jennifer Scheuer, assistant professor in printmaking at Purdue University, and I began collaborating on a series of collages titled #PandemicFridge. The project investigates the idea of care, nourishment and sustainability through the motif of the fridge, both literal and metaphorical. Our practice emerged from the pandemic and is indelibly marked by it: the new ways of working we have developed are informed by this experience as we were forced to find workarounds and new avenues to pursue our workThis article is published as Iancu, R., #PandemicFridge: Collaboration at a Distance and the title of the journal is IMPACT Printmaking Journal.; https://impact-journal-cfpr.uwe.ac.uk/index.php/impact/article/view/110/117.

Agriculture productivity gains and their distribution for the main EU members
No full textInternational audienceThis article seeks to highlight the performance of the farm sector in the main EU countries. Based on the productivity surplus account method (PSAM), our performance analysis includes all elements of the profit and loss account, which is one of the limits of the traditional index number approach. Moreover, this method also shows the way in which productivity gains observed in each country have been distributed among the main stakeholders. A specific focus is on the state’s as well as the farmers’ roles in this distribution game
