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

There is little research on children’s experiences of growing up in a popular tourist destination, where place and space are contested with visitors, migrants and temporary residents. Existing literature on young people’s experiences of their socio-spatial surroundings has focused predominantly on the rural/urban dichotomy, often neglecting to explore how identity and belonging are negotiated in complex community contexts such as tourist destinations. This paper reports on recent research that suggests that young people’s experiences of growing up in such an environment are nuanced and diverse, with their rich narratives disrupting socially constructed distinctions between the rural and the urban, merging experiences from both worlds.  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

在旅游消费升级驱动下,目的地品牌化日益成为国内外旅游业竞争的焦点。本文基于制度理论,从游客的全新视角探究在现有的制度环境中目的地的相关制度性行为如何影响目的地品牌资产。数据显示,旅游目的地不但可以通过制度性行为正向影响目的地品牌资产,还会通过品牌合理性的中介作用间接影响品牌资产;研究还进一步发现,不同于一般的精细加工可能性模型适用机制,目的地制度性行为效应的大小独立于目的地熟悉度的高低,目的地熟悉度并不是目的地制度性行为发挥效应的外部条件。本文的研究结论不仅展现了制度效力对目的地品牌建设的重要作用,还能进一步丰富目的地品牌资产研究的路径和方法,并为目的地营销实践提供有价值的参考。  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

以北京、武汉、西安城镇居民为例,探究旅游目的地选择行为的收入群体差异。研究发现,不同收入群体的旅游目的地选择行为存在明显差异,具体表现在:①不同收入群体的景区到访率均随距离的增加呈e指数衰减,但衰减速率存在收入群体差异,收入越高的群体,到访率距离衰减速率相对越小。②中国城镇居民的国内旅游目的地选择行为具有“距离择近,景点择高,经济择富”的“三择”倾向,但不同收入群体的“三择”程度不同,收入越低的群体,“距离择近,经济择富”的倾向越明显。③不同收入群体到访率空间分异趋势一致,但高到访率空间大小不同,收入越高的群体,高到访率空间越大。④目的地亲景度存在收入群体差异,收入越高的群体,目的地亲景度越高。  相似文献

ABSTRACT

While the impact of aeromobility on the growth of tourism and its destinations is well documented, the role of aeromobility in the process of experiencing and shaping place with specific regard to tourist destinations has received little attention from scholars. With the growth of commercial aviation and the increasingly mundane nature of the experience within mass tourism, I draw attention to the touristic experience of flying as the activity beyond its role in arriving at the destination. After a brief review of the genealogy of aeromobility and tourism, I reflect on examples of tourist aeromobility in Cape Town, South Africa in order to theorise the aeromobile tourist gaze. This paper analyses mobile testimonies from online travel reviews from airborne tourists performing helicopter ‘flips’ over Cape Town. Results highlight the need to focus on flying as tourism itself while they illustrate the role it plays in the aeromobile tourist gaze, a unique perspective and experience of the tourism destination as ‘tourism from above’ that emerges from the touristic dimensions of flight including the destination, the flying device and flight route. The findings underscore the role of flying-as-tourism. The aeromobile tourist gaze thus spectacularises the destination and disrupts the relationship between tourists and place.  相似文献
