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

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.  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

Several studies had concluded that the police subculture holds values and attitudes that are distinct from the rest of the population. Among these values is a focus on law and order. While researchers agree that police tend to hold different values, they disagree on the source of the attitudes. Some had argued that the attitudes reflected differences regarding who was recruited for law enforcement careers while others said that the differences reflected changes that occurred to individuals after becoming officers. This study examined whether police officers and students enrolled in criminal justice/sociology classes held similar or different attitudes towards the Miranda warnings. The findings suggested that in some ways, the two groups perceived the warnings in dramatically different ways, while in other ways their differences were simply a matter of degree. Implications are provided.  相似文献

The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic symptomatology criteria: re-experiencing, numbing, and arousal.  相似文献
