Regional and Global Strategies of MNEs : Revisiting Rugman & Verbeke (2004)

Rosa, Benjamin ; Gugler, Philippe ; Verbeke, Alain

In: Journal of International Business Studies, 2020, vol. 51, p. 1045-1053

We describe the extent to which the world’s largest companies (in terms of revenues), achieve sales around the globe, and have been able to penetrate markets outside of their home region. We try to answer the following question: Has there been a recent increase in the world’s largest firms achieving a global sales orientation, meaning a balanced, global distribution of sales? Rugman &...

Rethinking the Euro as a Common Currency for Europe : Keynes’s Plan Revisited

Rossi, Sergio

In: Revista de Economía Crítica, 2019, vol. 27, p. 86-99

This paper sets off from the monetary–structural origins of the euro-area crisis, which is not a sovereign debt crisis, but a crisis due to a lack of payment finality at international level. The first section explains that international payments across the euro area are not, to date, final for the countries concerned, as the European Central Bank does not operate as settlement institution...

Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria

Pterosaurs were the first vertebrates to evolve powered flight1 and comprised one of the main evolutionary radiations in terrestrial ecosystems of the Mesozoic era (approximately 252–66 million years ago), but their origin has remained an unresolved enigma in palaeontology since the nineteenth century2,3,4. These flying reptiles have been hypothesized to be the close relatives of a wide...

Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus

Evers, Serjoscha W. ; Foth, Christian ; Rauhut, Oliver W.M.

In: PeerJ, 2020, vol. 8, p. e8493

Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...

Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago

Evers, Serjoscha W. ; Wings, Oliver

In: PeerJ, 2020, vol. 8, p. e8437

Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod dinosaurs, which we describe here for the first time. All of the theropod bones belong to relatively small individuals but represent a wide...

Der bedeutungsorientierte Kulturbegriff revisited - aus einer kulturwissenschaftlichen Perspektive = Revisiting the Semantic Concept of Culture from the Perspective of Cultural Studies

Blanchard, Olivier

In: Soziale Aspekte des Musiklernens, 2018, p. 277-290

Reflecting on the notion of culture is at the centre of the Germanic discourse on the approach to cultural diversity. While the contemporary understanding of the term is currently being vividly discussed, the corresponding epistemological prem-ises are often neglected. Consequently, one runs the risk of having an essentialist understanding of culture. This text, therefore, first discusses the...

Are meta-paths necessary?: revisiting heterogeneous graph embeddings

Hussein, Rana ; Yang, Dingqi ; Cudré-Mauroux, Philippe

In: Proceedings of the 27th ACM International Conference on Information and Knowledge Management, 2018, p. 437–446

The graph embedding paradigm projects nodes of a graph into a vector space, which can facilitate various downstream graph analysis tasks such as node classification and clustering. To efficiently learn node embeddings from a graph, graph embedding techniques usually preserve the proximity between node pairs sampled from the graph using random walks. In the context of a heterogeneous graph,...
