Ribbed moraines formed during deglaciation of the Icelandic Ice Sheet : implications for ice-stream dynamics
(2025) Aradóttir, Nína; Benediktsson, Ívar Örn; Helgadóttir, Erla Guðný; Ingólfsson, Ólafur; Brynjólfsson, Skafti; Farnsworth, Wesley R.; Faculty of Earth Sciences; Engineering and Natural Sciences
Investigations of the geomorphological fingerprints of palaeo-ice streams are essential for enhancing our understanding of ice-stream behaviour. Cross-cutting flowsets of palaeo-ice streams, during and following the Last Glacial Maximum, have been suggested in northeast Iceland based on the mapping of streamlined subglacial bedforms (SSBs). To increase our understanding of the dynamics of the Icelandic Ice Sheet (IIS) during deglaciation, we investigate transverse ridges, together with glacifluvial and ice-marginal landforms, within the largest flowset. The main emphasis is on the transverse ridges, which are primarily interpreted as ribbed moraines – the first to be described in Iceland. Morphological data are combined with sedimentological analyses of the ribbed moraines. Our results show that the ribbed moraines are composed of pre-existing material, often exhibiting a base of stratified glacifluvial sediments draped with subglacial till. Deformation and thrust structures within both units suggest compressional flow during the formation of the ridges. Our results suggest the ribbed moraines develop due to velocity gradients under the lateral shear margin of an ice stream based on their distribution and often oblique orientation in relation to SSBs. The ribbed moraines superimpose and thus post-date the SSBs, signifying the waning stage of ice streaming. We suggest that the ridges formed during ice-stream shutdown following the Younger Dryas and/or Preboreal re-advances. Eskers and ice-marginal landforms imply channelized water drainage during the final deglaciation interrupted by short-lived re-advances. This study has implications for the style of deglaciation associated with ice streaming in the northeastern part of the IIS. We characterize the role of ribbed moraines within the ice sheet and identify directions for future work.

Globalisation and Court Practice in Iceland : New Case Law of the Supreme Court in Relation to the EEA Agreement and European Convention on Human Rights
(Springer Science and Business Media B.V., 2021) Thorsteinsdóttir, Halldóra; Department of Law
This article examines the status of international treaties in Iceland law and how Icelandic court practice has developed in recent years in that area. With regard to the relationship between domestic law and international law, Iceland adheres to the principle of dualism. This means that international law does not come into force as Icelandic law unless implemented by the legislator. As a result, Icelandic Courts will not, in general, apply provisions of international treaties unless they have been incorporated into Icelandic statutory law. However, this does not mean that international obligation are not fulfilled, as Icelandic Courts will seek to interpret domestic law in line with international obligation to the extent possible. If an international treaty has been implemented into Icelandic law, its provisions are binding like other domestic law. With regard to the EEA Agreement, Icelandic Courts will seek to interpret national law in accordance with EEA obligations and follow the judgments of the EFTA Court if the Icelandic provision in question is open to such an interpretation. With regard to the European Convention on Human Rights, Icelandic Courts will even go a step further, as recent judgments show that Icelandic Courts tend to interpret the human rights provisions of the Icelandic Constitution in line with interpretation laid down by The European Court of Human Rights, even in cases where such an interpretation does not exactly fit within the direct wording of the provision in question. This is due to a special connection between the human rights chapter of the Icelandic Constitution and the Convention, as one of the legislators’ main goals when amending the Constitution in 1994 was to bring the human rights chapter more in line with the Convention.

Which types of resources are necessary to achieve competitive advantage?
(2008) Lechner, Christian; Gudmundsson, Sveinn Vidar; Department of Business and Economics
In this article we test simultaneously various hypotheses of the RBV by taking into ac-count trade-offs and reinforcing effects between resources. Data consisting of 129 teams in the European professional soccer leagues between 1998 and 2003 was used to predict which types of resources are most significantly associated with firm perform-ance. The most important finding from this study is that socially complex intangible capabilities such as group routines have a positive impact on performance. According to our results, complementary factor markets for valuable resources do exist and their acquisition cannot be reduced to information asymmetry. We propose that causal am-biguity is about making difficult decisions with inherent trade-offs rather than about lack of understanding.

Who is ERIC? The politics and jurisprudence of a governance tool for collaborative European research infrastructures
(2019) Moskovko, Maria; Astvaldsson, Arnljotur; Hallonsten, Olof; Department of Law
Pan-European research infrastructures (RIs) have been labelled a 'pillar' of the European Research Area initiative (ERA) and 'engines' which are expected to drive forward the European Union (EU) economy by advancing its science and technology and ultimately its competitiveness on the global arena. The focus of this article is on the origins and nature of a policy tool named the European Research Infrastructure Consortium (ERIC), introduced by the EU in 2008 specifically for the purpose of stimulating and simplifying the set-up and operation of pan-European RIs. The article offers an analysis of ERIC from the perspectives of legal, organisational and science policy studies. The findings demonstrate that enactment of the legal instrument signals the increasing involvement of a supranational body in a traditionally intergovernmental context of science policy. ERIC as a legal framework is characterised by its flexible nature in the sense that members of ERIC enjoy a significant discretion as to, for example, internal structure and financing. The taxonomy of twenty RIs which have to date been set up under ERIC status underlines the all-encompassing nature of the legal tool, which raises a number of further scholarly questions addressed here.

Entrepreneurial orientation, firm strategy and small firm performance
(2014-02) Lechner, Christian; Gudmundsson, Sveinn Vidar; Department of Business and Economics
This article explores how individual entrepreneurial orientation dimensions influence the relationship between competitive strategy and firm performance. The findings show the different impacts of individual entrepreneurial orientation dimensions on competitive strategy and the effects of cost leadership and differentiation on performance. Innovativeness is related most highly to differentiation strategy. Risk-taking and competitive aggressiveness are negatively associated with both differentiation and cost leadership strategies. Both differentiation and cost leadership strategies are positively related to performance. This study refines our understanding of the effects of entrepreneurial orientation on small firm performance.
