ABSTRACT

Listed events are policies enacted by states to protect the free-to-air rights of specific television and radio broadcasts that are identified as being of particular national significance. Some states (including the UK, Belgium, and Argentina) have begun to adopt these listed events policies, typically regarding significant national sporting events. We re-conceptualize listed events as a practical means by which to protect the intangible cultural heritage of states – an issue addressed by international institutions such as ICOMOS and UNESCO. Furthermore, we engage in a critical analysis regarding both the merits and potential problems involved in the possibility of Canada adopting listed broadcasting events policies, specifically involving hockey broadcasts.  相似文献

ABSTRACT

This paper looks at the effectiveness of the policy of non-discrimination towards minorities in the preservation of minority cultural heritage, constructing a case study within Albania. After defining the key terms used, this paper examines the legal framework of non-discrimination towards minorities in its historical development and looks into the state of preservation of minority cultural heritage on the ground throughout the 2010s combining extensive field-work with interviews with key representatives of ethnic minorities in Albania. The poor state of preservation of minority cultural heritage is mostly attributed to under-financing and the insufficient policy of non-discrimination. As I demonstrate, in the case of minorities with a kin-state in the region, most notably Greece, as well as the heritage claimed by neighbouring states, primarily Turkey, the policy of non-discrimination and the practice of under-financing paves the way for external involvement in the protection of cultural heritage, in pursuit of international political agendas. The paper concludes that more needs to be done for the protection of minority cultural heritage in Albania.  相似文献

ABSTRACT

Taking into consideration the transnational dimension of Fascism that had its epicentre in Italy ? as Mussolini’s purpose of “marching throughout the streets of Europe and the World” plainly illustrates ? this article explores the connections between the Italian Fascist regime and the Portuguese Estado Novo during the interwar period. From the moment Fascism became attractive for Portuguese intellectuals, state officers, and politicians, until it became a colonial threat to the Portuguese empire, the cultural diplomacy apparatuses of the two countries will be analysed from a balanced, bi-lateral perspective, encompassing actors, transferences, and resistances.  相似文献

ABSTRACT

Nowadays, Sonic Pulse Velocity tests (SPV tests) are widely applied for detecting the morphology, hidden defects, and voids within structural elements. This technique, largely applied because non invasive and easy to perform, reveals particularly adapt in the case of ancient buildings, where usually any damage is not tolerated due to the historical preservation requirements. Moreover, recently the SPV tests have been also applied with tomography technology to obtain images of sonic speeds from which it is possible to rapidly reconstruct the internal elements morphology.

In this article, the results of some SPV tomographies regarding masonry elements are presented. The tests are carried out with the aim of establishing consistency and accuracy of this technique in determining the morphology of the investigated elements. The influence of investigation points number and noise smoothing is taken into account, too. At first, the results of a tomography derived from synthetic data of an ideal section are shown. Then, the SPV tomographies of some masonry specimens and of elements sections of a real case study are illustrated and compared among them.  相似文献

Abstract: To achieve a world‐class city capable of attracting business in a competitive global market, the municipal government of Cape Town, South Africa, like many cities of the global North, has adopted a model of urban revitalization popularized by New York City: business or city improvement districts (BIDs or CIDs). By examining CIDs in city center Cape Town, the paper casts light on the socio‐spatial relationship facilitating the neoliberal post‐apartheid regime and its governance. Analyzing discursive and spatial practices of Cape Town Partnership, the managing body of downtown CIDs, from 2000 to 2006, the paper reveals its difficulties in stabilizing the socio‐spatial relations of a transnationalizing urban revitalization strategy and rejects the view of CIDS as simply a global roll‐out of neoliberal urban policies. It highlights how CIDs are challenged from both within and outside of their managing structures by contentious local issues, and in particular by vast social inequalities and citizens' historical struggle for inclusive citizenship and the right to the city. Whether and how CIDs' inherent limitations can be overcome to address socio‐spatial inequalities is an open question.  相似文献

Abstract

In this study, we explore how tension between ‘culture’ and ‘industry’ can be effectively dealt with in promoting cultural industry, taking the Chinese embroidery sector as an example. The diverging performance of two leading centers of Chinese embroidery production suggests that local adaptive and networking capabilities are essential in creating a new path out of the tension, and these capabilities are largely determined by local openness/flexibility, entrepreneurship, and linkage capacity. In Changsha, cultural conservatism prevails, and the local embroidery sector largely maintains traditional product styles and target customers, sticking to the historic path. It is in question, however, whether such a strong bias toward the high-culture segment of the industry is good for cultural heritage protection in the long run, given that the industry at standstill has faced increasing challenges in sustaining a solid local pool of skilled labor. In contrast, Suzhou’s local embroidery sector has actively responded to the changing market environment, through increased product segmentation and customization as well as intra/cross-industry collaboration. Such a flexible, scale-up strategy has helped the industry attract local talent and meet the market demand, while maintaining space for high-end artistic products.  相似文献

彩绘类文物的彩绘研究和提取保护是考古工作的重点。但彩绘类文物因其自身的脆弱性而难以保存,需要进行一定的修复加固保护。现有加固保护材料由于大多与文物本体材质存在差异,致使加固保护长时间后,会与本体形成开裂,甚至剥离,宏观表现为“保护性破坏”。本研究着眼于使用彩绘类文物中传统的胶结材料,即动物明胶,但因明胶特有的溶胶-凝胶性,难以直接在文物上使用。因此,本研究首次提出将明胶微米化、纳米化,以“先渗透,再交联”的方式,有效回避明胶的溶胶-凝胶性,实现原材料保护修复。实验使用条件温和的乳化交联法,制备出尺寸为2~4μm的明胶微球,使用扫描电镜、红外光谱对其进行表征,并在模拟彩绘样块上进行透气性以及大红染色观察渗透性等的实验,初步证明作为加固剂的明胶微球新材料基本符合文物保护材料的标准要求。在今后更多的实验测试下,明胶微球有望投入使用。  相似文献
