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

Abstract

Historical materialism envisages law-like tendencies (‘scientific’ Marxism) promoting the development of productive forces and, concurrently, a political praxis (‘active’ Marxism) requiring human intervention. These positions give rise to conflicting interpretations of Marxism: first to understand society, second to change it – to abolish economic exploitation. The twentieth century witnessed a shift in the locus of the contradictions of capitalism to the economically dependent territories of the imperial powers. Socialist parties, when in power and adopting a Leninist political praxis, furthered modernisation and were successful in reducing economic exploitation. The paper addresses the relationship between the scientific and praxis components of Marxism in contemporary global capitalism. It considers post-Marxist interpretations of the changing class structure, the rise of identity politics and the evolving nature of capital. Forms of domination, oppression and discrimination (bureaucracy, patriarchy, racism, militarism and credentialism) give rise to their own distinctive forms of power relations. It is contended that they should not be equated with Marx’s crucial insight into the nature of economic exploitation. Many current Marxist (and ‘post-Marxist’) writers adopt a ‘scientific’ position emphasising the inherent contradictions of capitalism. The author claims that without appropriate political praxis, the resolution of such contradictions is unlikely to transcend capitalism.  相似文献

In the early 1970s, Grand Canyon National Park intended to designate its land to “Wilderness,” including the controversial Colorado River corridor. However, by the end of the 1970s the potential for Wilderness designation was off the table, and would never seriously return for genuine consideration. Using Schattschneider's model of conflict, we explain how the organization of this conflict privileges the “causal story” of Wilderness opponents, and therefore why the canyon is not designated. It is our contention that members of Congress will not stand forward to support Wilderness designations without simultaneously providing benefits for extractive land use because (1) congressional representatives are more penalized for supporting than opposing Wilderness designations, (2) Wilderness advocacy groups do not pressure congressional delegates as firmly as opposition groups, and (3) key local congressional members are not likely to see Wilderness as a salient issue worth the risk of negative exposure. If these findings hold, the implication is that we may have reached the end of significant Wilderness designations in highly visible areas, unless critical aspects in land use conflict change.  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
