An increasingly salient policy innovation pursued by LGBT+ rights groups and socially liberal policy entrepreneurs is the right of trans people to bring their legally recorded sex in line with their lived gender by way of self-identification. In response to these moves toward trans inclusion, a unique coalition of trans-exclusionary (gender critical) feminists and traditionalist conservatives has emerged to challenge these reforms. This coalition of policy opponents, mirroring historical issue frames that present homosexuals as predatory sexual deviants, campaign on a salient issue frame that presents transgender individuals and the expansion of trans rights as an inimical threat to the security, safety, and welfare of (cisgender) women, particularly in single-sex spaces. In this paper, we address two questions. First, we ask: do trans-exclusionary “protect women” issue frames over the alleged threat of trans persons to (cis) women shape mass public opinion? Second, we ask: in a relatively LGBT+ friendly policy environment, who supports the right to self-identification for trans individuals? We answer these questions via an original pre-registered survey experiment embedded within the 2021 Scottish Election Study. We find that trans-exclusionary issue frames appealing to (cis) women's safety significantly depress support for trans rights, particularly among women respondents. Highlighting these concerns is an effective means of increasing already robust opposition to reforms designed to improve the welfare of transgender individuals, which should be of concern for proponents of self-identification policies.  相似文献

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.  相似文献

As social and cultural contexts change and globalization spreads, the number of transnational-marriage migrants mainly from Southeast Asia has increased in Taiwan. Using institutional ethnography, this article investigates the roles of local non-governmental organizations (NGOs) and projects aimed at helping foreign spouses to adapt to their new life. I mainly elaborate that NGOs emerge as important actors in assisting and empowering transnational spouses to ‘become locals’. In empowerment projects, foreign spouses are given a voice to elaborate themselves. However, this article elaborates that these projects are a scheme of education to shape each such migrant into a proper ‘Taiwanese wife/mother/daughter-in-law’. Also, these projects particularly promote ‘exoticism’ of migrants and become key sources of how local people understand the images of ‘foreign spouses’. As a result, though NGOs play positive roles in empowering foreign spouses, we need to be aware that NGOs’ efforts may ironically become a mechanism to strengthen transnational spouses’ gender roles and cultural stereotypes.  相似文献

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.  相似文献

中共十六大报告有关台湾问题的分析很精辟,不但包含了我党以往行之有效的政策,而且根据目前海峡两岸形势的变化提出了一些新的主张,概括起来就是五个坚持、三个新意,明确了今后对台工作的思路和重点.当前,台湾的"台独"势力利用台湾岛内的省籍情结和台湾同胞"出头天"的思想,将台湾人民的台湾意识向"台独"方面引导,造成了我们统一前景的严峻形势,而"出头天"思想的产生与中国近代史特别是台湾近500年历史对台湾民众心态的影响是分不开的,只有了解和理解广大台胞的心态,才能有针对性地做好新时期的对台工作.  相似文献

The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.  相似文献

清中期以前,越南被视为藩属,清廷未曾与其划分明确界线。中法战争后清廷与法国签订《中法会订越南条约十款》,越南与清朝藩属关系断绝,划界之议遂启。光绪十一年,清廷派邓承修与法国官员进行划界事宜谈判,经过冗长的交涉辩论,最终双方签订界约、绘制界线舆图。台北“故宫博物院”藏邓承修与法国勘界官员所订条约、界图和相关档案,是还原这段桂越段边界交涉情形的重要资料。  相似文献

Studies of political attention often focus on attention to a single issue, such as front‐page coverage of the economy. However, examining attention to a single issue without accounting for the agenda as a whole can lead to faulty assumptions. One solution is to consider the diversity of attention; that is, how narrowly or widely attention is distributed across items (e.g., issues on an agenda or, at a lower level, frames in an issue debate). Attention diversity is an important variable in its own right, offering insight into how agendas vary in their accessibility to policy problems and perspectives. Yet despite the importance of attention diversity, we lack a standard for how best to measure it. This paper focuses on the four most commonly used measures: the inverse Herfindahl Index, Shannon's H, and their normalized versions. We discuss the purposes of these measures and compare them through simulations and using three real‐world datasets. We conclude that both Shannon's H and its normalized form are better measures, minimizing the danger of spurious findings that could result from the less sensitive Herfindahl measures. The choice between the Shannon's H measures should be made based on whether variance in the total number of possible items (e.g., issues) is meaningful.  相似文献

芥川龙之介一生共创作了148个短篇作品,涉猎女性形象的作品共76篇,其中女性形象色彩浓重38篇,涵盖知识女性、劳动女性、农妇甚至妓女等多个层面。这些形形色色的女性形象不仅如实地反映了作者的审美指向及其女性观,也浓缩了当时女性所处的社会地位和境遇。本文将其女性形象分为古典、现代与中国题材三大类,在分析芥川对女性所持态度的同时,考察作为大正时期知识分子的精英,其笔下诸多女性形象的文化内涵。  相似文献
