"文学"这一全然晚近的词在诞生之初,便与虚构有着某种密切而又复杂的联系。这种联系并非现今大众观念中根深蒂固的"文学虚构即虚假"——将自然真实与文学艺术所含有的虚构进行简单化的二元对立——的观念,而是一个更加值得深思与探讨的话题。因此,可以通过探讨文学本质同虚构间的联系来摈弃精神锈斑,在粗略的真假对立之外,尝试追寻属于文学与虚构的另一种答案。  相似文献

ABSTRACT

Since 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

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

Why did the Punjab bear the brunt of the mass violence and the migration that accompanied the partition of India? This paper makes the case for analytical eclecticism by showing that the following three explanations – centred respectively on democratisation, nationalism, and ideas; the commitment problem; and the security dilemma – account for the violence/migration in the different stages in the run-up to the partition of India. Instead of arguing that ‘everything mattered’, this paper elucidates the complex causality at work by demonstrating how these factors interacted with one another during the different stages leading to India’s partition.  相似文献

This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain.  相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献
