Research on the Strategy of Multinational Enterprises : Key Approaches and New Avenues

Dabic, Marina ; González-Loureiro, Miguel ; Furrer, Olivier

In: Business Research Quarterly (BRQ), 2014, vol. 17, p. 129-148

Over decades, research on multinational enterprises’ (MNEs) strategies has been anchored in internalization theory. Strongly grounded in transaction cost economics to explain foreign market entry, it hardly explains how MNEs can build and sustain a competitive advantage. Thus, this paper aims at understanding how the nature of strategic thinking has influenced the research in the field of...

Optical conductivity of the type-II Weyl semimetal TaIrTe4

Mardelé, F. Le ; Santos-Cottin, D. ; Martino, E. ; Semeniuk, K. ; David, S. Ben ; Orbanić, F. ; Novak, Mark ; Rukelj, Z. ; Homes, C. C. ; Akrap, Ana

In: Physical Review B, 2020, vol. 102, no. 4, p. 045201

TaIrTe4 is an example of a candidate Weyl type-II semimetal with a minimal possible number of Weyl nodes. Four nodes are reported to exist in a single plane in k space. The existence of a conical dispersion linked toWeyl nodes has yet to be shown experimentally. Here, we use optical spectroscopy as a probe of the band structure on a low-energy scale. Studying optical conductivity allows us to...

Preferential out-of-plane conduction and quasi-one-dimensional electronic states in layered 1T-TaS 2

Martino, E. ; Pisoni, A. ; Ćirić, L. ; Arakcheeva, A. ; Berger, H. ; Akrap, Ana ; Putzke, C. ; Moll, P. J. W. ; Batistić, I. ; Tutiš, E. ; Forró, László ; Semeniuk, K.

Layered transition metal dichalcogenides (TMDs) are commonly classified as quasi-two-dimensional materials, meaning that their electronic structure closely resembles that of an individual layer, which results in resistivity anisotropies reaching thousands. Here, we show that this rule does not hold for 1T-TaS2—a compound with the richest phase diagram among TMDs. Although the onset of ...

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...
