This paper proposes a novel approach to detect differential item functioning (DIF) among dichotomously scored items. Unlike standard DIF methods that perform an item-by-item analysis, we propose the “LR lasso DIF method”: logistic regression (LR) model is formulated for all item responses. The model contains item specific intercepts, an effect of the sum score and item-group interaction (i.e. DIF) effects, with a lasso penalty on all DIF parameters. Optimal penalty parameter selection is investigated through several known information criteria (AIC, BIC and cross-validation) as well as through a newly developed alternative. A simulation study was conducted to compare the global performance of the suggested “LR lasso DIF” method to the logistic regression and Mantel-Haenszel methods (in terms of false alarm and hit rates). It is concluded that for small samples the LR lasso DIF approach globally outperforms the logistic regression method, and also the Mantel-Haenszel method, especially in the presence of item impact, while it yields similar results with larger samples.

En 140/39 av. J.-C., une mission romaine composée, entre autres, de Scipion Emilien et du philosophe Panétios visita les alliés orientaux de Rome et se rendit notamment à Alexandrie. Le roi Ptolémée VIII y accueillit officiellement ces hôtes prestigieux, vêtu d’un habit étrange : un chiton long et subtil, dont les auteurs anciens réfèrent unanimement l’effet efféminé et caricatural, au point de susciter le rire des Romains et une condamnation du luxe effréné et décadent du royaume égyptien par comparaison avec la sobriété romaine. Il a fallu attendre une étude de H. Heinen en 1983 pour reconnaître, d’une part, l’envergure idéologique du lien entre la tenue de Ptolémée VIII – en fait empruntée à l’iconographie hellénistique de Dionysos – et la mise en scène officielle de la tryphè et du pouvoir royal et, de l’autre, le sens politique de la représentation caricaturale qu’en donna probablement déjà Panétios, représentation qui fut relayée et amplifiée par toute une tradition historiographique philo-romaine, qui se développa tout au long de la conquête romaine de la Méditerranée et ensuite à l’occasion du conflit entre Octavien et Antoine. Cette tradition nous a transmis, par le biais des auteurs de l’époque impériale, un discours fondé sur l’opposition entre Rome (et l’Italie), vertueuse source de citoyens et de soldats, et l’Orient dégénéré. Dans un tel cadre, Dionysos et le dionysisme sont sollicités pour servir à la construction d’un modèle accusatoire contre les ennemis de Rome, incarnant le désordre dans une dimension à la foi individuelle et institutionnelle. Mais est-ce que cette vision idéologique nous donne un portrait satisfaisant des rapports réels entre Rome et Dionysos / Bacchos / Liber Pater ? En partant de cette question, je propose dans ma contribution une approche visant à analyser, à l’aide de sources aussi littéraires que documentaires, les contextes de contact entre Rome et Dionysos de l’époque hellénistique au début du Principat, pour essayer de mettre en relief les relations entre, d’une part, la répulsion et le refus idéologiques du dionysisme, de l’autre les démarches d’appropriation et d’adaptation, à la culture romaine, de traits caractérisant les cultes hellénistiques de Dionysos et leurs utilisation dans la mise en forme des pratiques du pouvoir et de leurs représentations.

In the framework of instrument calibration, straylight issues are a critical aspect that can deteriorate the optical performances of instrument. To cope with this, a new facility is designed dedicated for in-field and far field straylight characterization: up to 10-8 for in-field and up to 10-10 for far field straylight in the visible to NIR spectral ranges. Moreover, from previous straylight test performed at CSL, vacuum conditions are needed for reaching the 10-10 rejection requirement mainly to avoid air/dust diffusion. The major constrains are to design a straylight facility either for in-field and out-field straylight measurements. That requires high dynamic range at source level and a high radiance point source allowing small diverging collimated beam. Moreover, the straylight facility has to be implemented into a limited envelope and has to be built with vacuum compatible materials and black coating. As checking the facility performance requires an instrument better than the facility itself, that is no easy to find, so that the performances have been estimated through a modelisation into a non sequential optical software. This modelisation is based on CAD importation of mechanical design, on BRDF characteristics of black coating and on statistical averaging of ray tracing at instrument entrance. [less ▲]

This book provides a cultural and social history of the rise and legitimation of the concept of dynastic continuity in the early history of the Ptolemaic Empire. The scope of the study is therefore neither to provide a general overview of third-century Ptolemaic history, nor to discuss in detail the administrative and economic structures of the Ptolemaic state. Rather, its purpose is to investigate the ways by which the first Ptolemies negotiated and constructed a representation of their power as a dynastic house aspiring to universal dominion, protected by the gods and legitimately continuing the heritage of the Macedonian and Egyptian monarchies. It is argued that they managed to do so by operating within different socio-cultural and ethnic milieus and by pursuing their strategies on a two-fold level: on the one hand, by continuously reshaping the relationship between the present events of the ruling house and its historical and mythical past, so as to adapt it to new political and cultural agendas; on the other hand, by shifting the border between the spheres of human and divine power in order to ensure themselves the legitimacy and loyalty stemming from religious thought and practice. Discussed evidence comprises Greek and Egyptian sources, literary and documentary texts, iconographic and archaeological evidence from the Macedonian conquest of Egypt under Alexander to the ascension of Ptolemy III Euergetes. Whenever possible, a new, encompassing evaluation of old evidence has gained new impetus from the intensive analysis of newly published sources. Secondly, the complex cultural and social factors operating in the construction and legitimation of the Ptolemaic dynasty have been discussed by drawing on the contribution of up-to-date scholarship in cultural and religious history as well as in sociology. The rooting of Ptolemaic power in Egypt and the Eastern Mediterranean is studied as the movement from the immediate but unstable right of conquest established by Alexander, and subsequently claimed by the satrap Ptolemy, to the development of a mature and coherent system of power practices and representations. The structure of the book is meant to provide readers with a chronological and thematic discussion ranging from Alexander’s conquest of Egypt to the first years of Ptolemy III. However, the six chapters that constitute this study can also be read separately as they are conceived as the monographic treatment of major moments or aspects of the cultural, political, and religious history of the early Hellenistic period. Chapter 1 deals with the premises of Ptolemaic power in Egypt by focusing on the time of Alexander’s conquest. The implications of Alexander’s sonship to Zeus Ammon in propaganda and in religion are reviewed by drawing attention to the plurality of audiences (Macedonians, Greeks, Egyptians) for which this motif was conceived and used. Chapter 2 discusses the conflicting patterns of legitimation in the age of the Successors and how Ptolemy exploited them in his rise from satrap to king. Some seminal moments of Ptolemy’s career are re-examined: the acquisition of Alexander’s corpse as a source of embodied legitimacy; the interactions between the leader and pre-existing Macedonian and Egyptian elites as they appear in assembly scenes of Greek historiography and in the hieroglyphic Satrap stele; Ptolemy’s help to the Rhodians against Antigonus and Demetrius and the entanglement between royal charisma and religious honours. Chapter 3 focuses on the figure of Dionysus in Ptolemaic religion and culture from a twofold perspective. Firstly, the chapter provides an innovative analysis of the religious and ideological role of Dionysus in Ptolemy II’s Alexandrian procession described by Callixeinus of Rhodes. Secondly, it aims at offering a contribution for a reappraisal of the figure of Dionysus, of his cults and of the role of his figure within the larger context of the Ptolemaic Empire in the third century BC. Chapter 4 discusses the patterns of divinization of Arsinoe II within the royal couple through the most complete documentary dossier collected thus far on the subject. Rather than constituting the aim of the research, the debate concerning the chronology of Arsinoe’s death and divinization has provided the rough framework for a new investigation of how the image of a solid royal couple was invented and spread in religious life and in propaganda. Diachronic developments in the configurations of the dynastic couple are traced through Greek and Egyptian evidence and discussed in relation to the changing of political agendas during the reign of Ptolemy II. Chapter 5 studies the contribution of Ptolemy III to the construction of Ptolemaic dynastic continuity through old and new evidence, notably by providing fresh observations concerning the recently published decree of Alexandria (243 BC) for the understanding of Ptolemaic royal festivals in general and, more in particular, for the history of the festival Ptolemaia in the second half of the 3rd century BC. Chapter 6 breaks with chronological continuity to trace, through literary and documentary evidence from the Roman period, the development of the tradition envisaging Alexander’s body as a talismanic relic protecting the city of Alexandria. The purpose of this epilogue is to provide a methodological essay of interpretation of cultural traditions in the longue durée, when patterns of continuity developed under the Ptolemies were separated from their original context of diffusion and consequently were re-used to shape the civic identity of Alexandria within the new and broader framework of the Roman Empire. Although focus on the construction of a dynasty as a sequence of legitimate, kindred holders of monarchic power makes Ptolemaic kings and queens the central object of this study, it is argued that sovereigns cannot be considered as the sole holders of the initiative in the political, ideological and religious processes relating to the construction of royal and dynastic imagery. On the contrary, it appears that social agents other than the holders of supreme leadership not only reacted to top-down stimulation, but they also constructed, for their own use, representations of the monarchs that interacted with the message issued by the central power. From this perspective, therefore, dynastic continuity results from the intertextual combination of a variety of ideological and religious motifs stemming from different agents and occasions of communication.

Dans le cadre de la littérature de l’exil, il a souvent été question de subjectivités entre-deux, de sujets in-between, et de réflexions entre un « ici » aliénant et un « là-bas » idéalisé. En réaction à cette pensée binaire et suite aux réflexions postcoloniales, les mouvements migratoires sont aujourd’hui célébrés et associés aux figures d’identités composées . Par ailleurs, notre compréhension des migrations a fortement évolué depuis une quinzaine d’années, on ne parle donc plus aujourd’hui de relocalisations unidirectionnelles et permanentes mais plutôt de communauté transnationale et de cultures globalisées selon un agencement postcolonial . C’est dans cette optique que j’observerai quelles sont les différentes masculinités issues de la diaspora dominicaine en confrontation dans le roman de Junot Díaz La Brève et Merveilleuse Vie d’Oscar Wao, et, face à ces tensions de genre, de quelle manière la subjectivité masculine d’Oscar Wao est singulière.
