ABSTRACT

Copyright is inherently intertwined with the development of technology and none more so than the advent of the Internet and sharing technologies. More recently, social media platforms have become the latest challenge for copyright law and policy. This article builds on the literature that recognises the underlying conflict between copyright and social networking sites (SNSs); namely that the basic implication of copyright is the restriction of copying, whereas the ethos of social networking is the promotion of sharing. In particular, this article focuses on the disparity between the restricted acts of copying and communication to the public under copyright law and the encouragement of sharing on SNS Instagram. In doing so, it contextualises the debate surrounding copyright and social media and provides an understanding of the legal implications of using Instagram. As such this paper analyses (1) the infringement of copyright protected work on Instagram, and (2) the user-agreement and licensing of copyright material on Instagram. This study concludes that the disparity between the principles of copyright and social media lead to confusion and vulnerability of users. Therefore, it is suggested that Instagram should better inform its users of the implications of sharing third-party content as well as the terms of its user agreement. This could be done by implementing a copyright strategy, which includes a notice and takedown system as well as investing in producing educational content for users. Perhaps SNSs, such as Instagram might be more motivated to take steps to recognise intellectual property rights if they were considered Internet Services Provides such as YouTube.  相似文献

The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal.  相似文献

While the concepts of race and ethnicity have been abused historically, they are potentially invaluable in epidemiology and public health. Epidemiology relies upon variables that help differentiate populations by health status, thereby refining public health and health care policy, and offering insights for medical science. Race and ethnicity are powerful tools for doing this. The prerequisite for their responsible use is a society committed to reducing inequalities and inequities in health status. When this condition is met, it is irresponsible not to utilize these concepts.  相似文献

Die von Deutschland nach Art. 59 Abs. 2 GG ratifizierten europ?ischen und internationalen übereinkommen zum Denkmal- und Kulturgüterschutz müssen in nationales Recht transformiert werden. W?hrend die L?nder im Rahmen ihrer Kompetenz (Art. 30, 70, 83 GG) Denkmalschutzgesetze erlassen haben, hat der Bund in einschl?gigen Gesetzen wie dem Bundeswaldgesetz den Denkmalschutz bisher nicht berücksichtigt. Dabei ist bei einem Waldanteil von 30% der Wald mit seinen historischen Kulturlandschaften und seinem Waldboden als Archiv der Natur- und Kulturgeschichte von besonderer Bedeutung. Da Deutschland 60 Jahre nach Kriegsende endlich auch ausdrücklich ein Kulturstaat werden soll, ist es an der Zeit, dass die Belange des Denkmalschutzes auch im Bundeswaldgesetz (z.B. §§ 1, 2, 9 oder 11 BWaldG) berücksichtigt werden. Einige Verpflichtungen zum Denkmal- und Kulturgüterschutz sind heute ohnehin bereits V?lkergewohnheitsrecht (Art. 25 GG).  相似文献

The EU has regulated chemicals since the late 1960s using both general and sectoral legislation, and exposure-based, hazard-based and risk-based decisions. A new proposal from the European Commission – on the Registration, Evaluation and Authorization of Chemicals (REACH) – will build on the experiences of the existing legislation and introduce some new concepts in the management of chemicals. This article is aimed at assessing the current chemical control mechanisms in the EU and those put forward in REACH to demonstrate how REACH is a new paradigm in chemicals management. REACH will carry forward today's experience and approach to the management of chemicals in the EU and introduces some novel aspects, such as utilizing market-based mechanisms and putting into operation the 'substitution principle'.  相似文献

In 1970, the Congress enacted the Organized Crime Control Act. Title IX of the 1970 Act is the Racketeer Influence and Corrupt Organization Act or RICO. This Act had its origins in legislation going back as far as 1934, but coming forward to 1961. The 1970 Act borrowed ideas from this earlier legislation, principally “enterprise,” but also the use predicate statutes to define “racketeering activity.” The ideas are not new, but their combination affects how prosecutors and law enforcement agents investigate, try, and sanction violations of the Act. RICO’s drafting also reflects organizational theory and economic analysis. The investigation and prosecution of a single crime committed by an individual on a single day and in a single place maybe done using one set of procedural and evidentiary rules. Nevertheless, the investigation and prosecution of patterns of diverse offenses committed by, through, and against licit and illicit enterprises require sophisticated procedures, evidentiary rules, and criminal sanctions. In addition, antisocial conduct is more than a challenge to the administration of criminal justice; it also requires the full panoply of civil sanctions, including public injunctions as well private enforcement of injunctive relief and treble damages. RICO has had a profound effect on the prosecution of organized crime, white-collar crime, and other forms of similar criminal behavior. William J. & Dorothy K. O’Neill Professor of Law, Notre Dame Law School; A.B. 1957, University of Notre Dame; J.D. 1960, Notre Dame Law School. Professor Blakey was the Chief Counsel of the Subcommittee on Criminal Laws and Procedures of the United States Senate Committee on the Judiciary in 1969-70 when the Organized Crime Control Act of 1970, Pub. L. No. 91-542, 84 Stat. 922 (1970) was processed, Title IX of which is the Racketeer Influence and Corrupt Organization Act or RICO. For a general treatment of the statute from a variety of perceptive, see the collection of law review literature in G. Robert Blakey & Kevin Roddy, “Reflections on Reves v. Ernst & Young: Its Meaning an Impact on Substantive, Accessory, Aiding, Abetting and Conspiracy Liability under RICO,” 33 Amer. Crim. L. Rev. 1345, 1348 n. 3(1996).  相似文献
