Compliance of the L5-S1 spinal unit: a comparative study between an unconstrained and a partially constrained system

A comparison between an unconstrained and a partially constrained system for in vitro biomechanical testing of the L5-S1 spinal unit was conducted. The objective was to compare the compliance and the coupling of the L5-S1 unit measured with an unconstrained and a partially constrained test for the three major physiological motions of the human spine. Very few studies have compared unconstrained and partially constrained testing systems using the same cadaveric functional spinal units (FSUs). Seven human L5-S1 units were therefore tested on both a pneumatic, unconstrained, and a servohydraulic, partially constrained system. Each FSU was tested along three motions: flexion-extension (FE), lateral bending (LB) and axial rotation (AR). The obtained kinematics on both systems is not equivalent, except for the FE case, where both motions are similar. The directions of coupled motions were similar for both tests, but their magnitudes were smaller in the partially constrained configuration. The use of a partially constrained system to characterize LB and AR of the lumbosacral FSU decreased significantly the measured stiffness of the segment. The unconstrained system is today's "gold standard" for the characterization of FSUs. The selected partially constrained method seems also to be an appropriate way to characterize FSUs for specific applications. Care should be taken using the latter method when the coupled motions are important.

Why Cherry-Picking Never Leads to Harmonisation: The Case of the Limitations on Copyright under Directive 2001/29/EC

The article examines whether the norms laid down in the Directive in relation to the exceptions and limitations on copyright and related rights can be conducive to a sensible degree of harmonisation across the European Union. Before discussing the degree of harmonisation achieved so far by the Directive, the first part gives a short overview of the main characteristics of the list of exceptions and limitations contained in Article 5 of the Directive. A comprehensive review of the implementation of each limitation by the Member States is beyond the scope of this article. The following section takes a closer look at three examples of limitations that have led to legislative changes at the Member State level as express measures towards the implementation of the Information Society Directive, that is, the limitations for the benefit of libraries, for teaching and research, and for persons with a disability. These exceptions and limitations were later on also identified by the European Commission as key elements in the deployment of a digital knowledge economy. The analysis will show that the implementation of the provisions on limitations in the Information Society Directive did not, and probably cannot, yield the expected level of harmonisation across the European Union and that, as a consequence, there still exists a significant degree of uncertainty for the stakeholders regarding the extent of permissible acts with respect to copyright protected works.

Limitations: The Centerpiece of Copyright in Distress

After the exclusive rights in copyright have been consolidated in a century-long historical development, limitations and exceptions have become the main instrument to determine the exact scope of copyright. Limitations and exceptions do not merely fine-tune copyright protection. Rather, they balance the interests of authors, rightholders, competitors and end-users in a quadrupolar copyright system. Understanding this is of particular importance in the digital and networked information society, where copyrighted information is not only created and consumed, but constantly extracted, regrouped, repackaged, recombined, abstracted and interpreted. However, serious doubts exist whether the present, historically grown system of limitations adequately balances the interests involved in the information society. Both the closed list of limitations allowed under Art. 5 of the EU Information Society Directive 2001/29/EC and a narrowly interpreted three-step test contained in Arts. 13 TRIPS and 5 (5) of the Information Society Directive appear as obstacles in the way of achieving the appropriate balance needed. This brief article outlines the issues involved which were discussed at the International Conference on “Commons, Users, Service Providers – Internet (Self-) Regulation and Copyright” which took place in Hannover, Germany, on 17/18 March 2010 on the occasion of the launch of JIPITEC.

Unsticking the centre-piece – the liberation of European copyright law?

Following European legislative initiatives in the field of copyright limitations and exceptions, policy flexibilities formerly available to mem- ber states has been greatly diminished. The law in this area is increasingly incapable of accommodating any expansion in the scope of freely permitted acts, even where such expansion may be an appropriate response to changes in social and technological conditions. In this article, the causes of this problem are briefly canvassed and a number of potential solutions are noted. It is suggested that one such solution – the adoption of an open, factor-based model similar to s 107 of the United States’ Copyright Act – has not received the serious attention it deserves. The fair use paradigm has generally been dismissed as excessively unpredictable, contrary to international law and/or culturally alien. Drawing on recent fair use scholarship, it is argued here that these disadvantages are over-stated and that the potential for the development of a European fair use model merits investigation.

Richtungsweisend oder eine nur begrenzt wahrgenommene Chance? Der Copyright-Code des Wittem-Projekts

Der „European copyright code“ des Wittem-Projekts von 4/2010 ist pragmatisch, konstruktiv-konservativ ausgefallen. Traditionell das Werk- und Autorenverständnis. Schrankenregelungen werden über einen hybriden Ansatz offen gehalten. Bildung und Wissenschaft werden nicht gerade verwöhnt. Die Wittem-Gruppe hat sich nicht in den „Treibsand visionärer Modelle“ begeben wollen. Ein guter Text, aber dann doch nicht wirklich wegweisend für den Umgang mit Wissen und Information in elektronischen Räumen, am ehesten noch durch den Vorschlag einer Schrankenbestimmung zur Begünstigung des wirtschaftlichen Wettbewerbs.

The Law Applicable to Online Copyright Infringements int ALI and CLIP Proposals: A Rebalance of Interest Needed?

The article discusses the problems of applicable law to copyright infringements online. It firstly identifies the main problems related to the well established territoriality principle and the lex loci protectionis rules. Then; the discussion focuses on the "ubiquitous infringement" rule recently proposed by the American Law Institute (ALI) and the European Max Planck Group for Conflicts of Law and Intellectual Propoperty (CLIP). The author strongly welcomes a compromise between the territoriality and universality approaches suggested in respect of ubiquitous infringement cases. At the same time; the paper draws the attention that the interests of "good faith" online service providers (such as legal certainty and foreseeability) have been until now underestimated and invites to take these interests into account when merging the projects into a common international proposal.

Liability for Copyright Infringements on the Internet: Host Providers (Content Providers) - The Geman Approach

Copyright infringements on the Internet affect all types of media which can be used online: films, computer games, audio books, music, software, etc. For example, according to German studies, 90% of all copyright violations affecting film works take place on the Internet. This storage space is made available to such infringers, as well as to others whose intentions are legal, by hosting providers. To what extent do hosting providers have a duty of care for their contribution to the copyright infringements of third parties, i.e. their users? What duties of care can be reasonably expected of hosting providers to prevent such infringements? These questions have been heavily debated in Germany, and German courts have developed extensive case law. This article seeks to examine these questions by assessing German jurisprudence against its EU law background.

Diverse Readings of the Court of Justice Judgments on Copyright Work

EU law’s impact on the meaning of the copyright work for a long time seemed limited to software and databases. But recent judgments of the CJEU (Infopaq, BSA, FootballAssociation [Murphy], Painer) suggest we have entered an era of harmonization of copyright subject-matter, after decades of focus on the scope of exclusive rights and their duration. Unlike before however, it is the Court and not the legislator that takes centre stage in shaping pivotal concepts. This article reviews the different readings and criticisms the recent case law on copyright works evokes in legal doctrine across the EU. It puts them in the wider perspective of the on-goingdevelopment towards uniform law and the role of the preliminary reference procedure in that process.
