ABSTRACTSince the late 20th century, the federal government has regulated colleges’ and universities’ handling of campus sexual and gender-based violence (CSGBV). Although the arc of history has bent toward establishing greater protections for victims of such violence, new proposed regulation by the U.S. Department of Education under the Trump administration focuses more heavily on ensuring due process rights for students accused of CSGBV. Most recently, in November 2018, U.S. Secretary of Education, Betsy DeVos submitted a proposed rule change to the regulation of Title IX of the Education Amendments of 1972. This article provides the historical context for this most recent proposed federal regulation of CSGBV and discusses the criticism of this proposal that, if it is implemented, students would become less safe in the ivory tower. 相似文献

ABSTRACTCopyright 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

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making. 相似文献

ABSTRACTMany liberals have been immodest in postulating that their own progressive, secular liberalism is the only one that can be justified in public reason. In Liberalism’s Religion, I articulate a more modest theory of liberalism and religion. While I personally endorse progressive secular liberalism, I argue that it is only one of the reasonable conceptions of liberal justice. This liberal modesty has profound, hitherto unnoticed implications for (i) the role of religious arguments in the public sphere, (ii) the legitimacy of religious establishment, and (iii) the justifiability of religious exemptions. In this article, I defend these three claims by providing replies to my critics. 相似文献

Numerous accounts reveal that congressional leaders often secure “hip‐pocket votes” or “if you need me” pledges from rank‐and‐file legislators. These are essentially options on votes. Leaders exercise sufficient options—pay legislators to convert to favorable votes—when those options will yield victory. Otherwise, they release the options. A model shows that this optimal strategy for leaders produces many small victories, few small losses, and losses that are, on average, larger than victories. We find precisely these patterns, hence strong evidence for vote options, in Congressional Quarterly key votes from 1975 through 2001 and in non‐key votes from the 106th Congress (1999–2000). 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

Prosecution history estoppel generally bars patent infringementunder the doctrine of equivalents when a claim is narrowed byamendment during examination, but the tangential relationcriterion preserves that doctrine when the claim is narrowedin a manner unrelated to the particular equivalent which, itis alleged, infringes the patent. 相似文献
