Les Reptiles Marins du toarcien (Jurassique inferieur) Belgo-Luxembougeois

Toarcian (Lower Jurassic) outcrops have yielded many marine reptiles Ichthyosauria, Thalattosuchia and Plesiosauria in Belgium and, principally, in Grand Duchy of Luxemburg. Their preservation allows a determination at a specific level as also the description of badly known anatomical characters. The study of ichthyosaurs required a systematic revision of the genus Stenoplerygius. A palaeogeographical synthesis of Toarcian marine reptiles is proposed. Important quantitative differences can be observed in the composition of marine reptiles' faunae from Württemberg (Germany), Yorkshire (England) and Luxemburg. This latter fauna is characterized by a predominance of animal well adapted for the life in open sea

Présence de Leptopterygius tenuirostris (Reptilia, Ichthyosauria) dans le Lias moyen de Lorraine belge

In this paper, a left humerus and epipodials of an Ichthyosauria, discovered in Pliensbachian from Differt (Belgian Lorraine) and preserved in the collections of the Institut royal des Sciences naturelles de Belgique, are described. This fossil is attributed to Leptopterygius tenuirostris (CONYBEARE, 1822). At the present time, this is the only fossil of an Ichthyosauria which can be identified at specific level, in Middle Liassic formations. Both geographical and stratigraphic distributions of this species are consequently enlarged

Developing Shopping Abilities to Empower: An Ethnography of Moroccan Women in Supermarkets

This article examines the specific abilities that Moroccan women develop as they start to participate in household provisioning, a traditional male task in Arab contexts. The findings of an ethnographic study in Casablanca, Morocco, suggest that women’s abilities to shop in supermarkets increase their power in their families and communities. This article furthers understanding of consumers’ vulnerability and adds to knowledge on global/local dynamics

A Commentary on the Dynamics of the Local and the Global, and the Representations of Minorities in Mediascapes

This commentary intends to extend knowledge about local identities with regard to their representations in the mediascape. It uses two focal MGDR papers and uncovers the opportunities for local identities to develop in global-local dynamics. This commentary reminds the interdependence between the global and the local and how local identities are formed. We discuss the accessibility of local identities and cultures

An Institutional Perspective on Climate Change, Markets, and Consumption across Three Countries

This manuscript enriches knowledge about consumers’ responses to climate change actions. Through the lens of institutional theory, it examines the findings of three studies run in France, Morocco and the United States. In Morocco, consumers are more responsive to climate change actions when they are managed at the level of their country, and company. Moroccan consumers express ambivalent emotions when their supermarket engages in actions to combat climate change. In France, consumers are less responsive when their country engage in climate change actions, but they display positive responses towards their supermarkets’ climate change actions. In the United States, the responses are mitigated. As shown in the three studies, institutional contexts have an impact on consumers’ responses to climate change actions. The manuscript further provides managerial implications to support marketing actions that combat climate change. It further raises climate-related issues, like corporate hypocrisy, and discusses the role of educators and other agents of change to address climate change

Representing Africa in the ‘Coming to America’ Films

Through an interpretive analysis of the two Eddie Murphy films Coming to America (CTA) and Coming 2 America , spaced nearly 30 years apart, this review essay underscores the persistence of Orientalist Othering of Africa. The negative images of Africa that are so engrained in people have been facilitated in significant part by a strategic, but perhaps unconscious, effort to socialize audiences into an identity construction process that casts Africans as inferior. Despite attempts at favorable depictions of Africa, these processes continue to play out

Intraskeletal histovariability, allometric growth patterns, and their functional implications in bird-like dinosaurs

With their elongated forelimbs and variable aerial skills, paravian dinosaurs, a clade also comprising modern birds, are in the hotspot of vertebrate evolutionary research. Inferences on the early evolution of flight largely rely on bone and feather morphology, while osteohistological traits are usually studied to explore life-history characteristics. By sampling and comparing multiple homologous fore-and hind limb elements, we integrate for the first time qualitative and quantitative osteohistological approaches to get insight into the intraskeletal growth dynamics and their functional implications in five paravian dinosaur taxa, Anchiornis, Aurornis, Eosinopteryx, Serikornis, and Jeholornis. Our qualitative assessment implies a considerable diversity in allometric/isometric growth patterns among these paravians. Quantitative analyses show that neither taxa nor homologous elements have characteristic histology, and that ontogenetic stage, element size and the newly introduced relative element precocity only partially explain the diaphyseal histovariability. Still, Jeholornis, the only avialan studied here, is histologically distinct from all other specimens in the multivariate visualizations raising the hypothesis that its bone tissue characteristics may be related to its superior aerial capabilities compared to the non-avialan paravians. Our results warrant further research on the osteohistological correlates of flight and developmental strategies in birds and bird-like dinosaurs
