Potential Use of Foamed Mortar (FM) for Thermal Upgrading of Chinese Traditional Hui-Style Residences

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m²·K/W, which is even higher than 0.67 m²·K/W for the code required in the hot summer/cold winter climate zone.     

Maritime Aspects of Medieval Siraf,Iran: a pilot project for the investigation of coastal and underwater archaeological remains

Siraf is well‐known archaeologically and historically as an ancient port in the Persian Gulf that prospered during the medieval period. Siraf played a leading role in facilitating maritime and terrestrial trade, connecting long‐distance Indian Ocean and China routes with those in the Gulf region. Despite its history, no previous research has been dedicated to the maritime infrastructure of Siraf. Through the ‘2012 Siraf pilot project’ a preliminary survey of the underwater and shoreline remains of this ancient port city was conducted. The site's location is unique in many respects to trade routes and logistical considerations; however, its maritime infrastructure is difficult to assess in light of the extensive threats to the site.     

Heritage transactions at the Festival of Pacific Arts

The Festival of Pacific Arts, hosted by a different Pacific Island state once every four years, is a prime site for the reproduction of the global discourse on heritage. Drawing on ethnographic research conducted at the festival, this paper focuses on how the concept of heritage is employed at the festival as both an instrument of statecraft and a tool for the assertion of grass-roots political and economic agency. We conclude that heritage in the context of the festival is a form of cultural practice involving relationships of power and inequality, expressed in transactions of ownership and value transformations that have become over determined by economic logic and the concept of property.     

Uncovering a Painful Past: Archaeology and the Holocaust

Abstract

Places connected to the Holocaust, and the physical evidence that lies within them, survive as reminders of the crimes perpetrated by the Nazis. Both the treatment of these sites and attitudes towards them have varied considerably in the years since the Second World War. In recent years, a number of archaeological investigations have been instigated by curators at Holocaust sites in a direct attempt to enhance visitor experiences and education programmes. Archaeologists have initiated investigations at other forgotten and dilapidated sites in an attempt to raise awareness of these places. This paper will discuss two case study sites where archaeological investigations have been undertaken and where attempts have been made to inform conservation, heritage management, and education strategies. It will highlight the various challenges that may arise in the course of developing dissemination tools and discuss strategies that have been adopted to account for them. Specifically it will focus on how archaeologists can present novel means by which to locate, record, and re-present the physical evidence of the Holocaust and how they can tell the stories of difficult heritage sites even when traditional forms of memorialization/muzealization is not wanted or practical.     

Community Engagement in Historical Site Protection: Lessons from the Elmina Castle Project in Ghana

Abstract

Engaging communities in the protection of heritage means that the communities living around the heritage sites are involved in the process of identifying issues that affect the conservation of these sites and can propose ways by which they can be addressed. In Ghana, the Elmina Castle project shows close collaboration between the communities living around these slave forts and castles, the legal custodians, and other stakeholders. This case study unpicks the process to show how the existing traditional systems were approached and involved. The result of this participatory collaboration is a strategic document which will be implemented to ensure proper protection of these sites in the wake of development and modernization.     

传承和共享:文化遗产保护的双重伦理向度

遗产本质上具有伦理性,在历史主义保护传统中隐含着以传承为中心的伦理向度;同时,当代遗产保护运动中"人类遗产"理念和传承共同责任,又提升了遗产的公共性,揭示出了遗产保护中的当代共享向度。在历史主义保护占据主导地位的情况下,当代人在遗产面前的主体共享诉求相对不足,近些年国际国内对这种现象有较多的批评和反思。在需要满足当代人共享愿望又不能废弃传承伦理向度的情况下,创新保护理念和方式,在利用中实现"文化再生产"也许是文化遗产保护的有效途径。     

国外文化遗产基金制度及其借鉴

文化遗产基金制度或与文物保护相关的艺术基金制度在西方发达国家已基本完善。基金会通过多渠道广泛地筹集资金,并有效地进行战略管理和再投资;同时,基金会的日常运作公正透明,具有完善的内外部监督机制。这些贯穿于基金运作各层面的制度及运作经验十分值得我国借鉴。     

Defining “Official” Built Heritage Discourses within the Irish Planning Framework: Insights from Conservation Planning as Social Practice

Conservation of built heritage is a key planning process and goal which shapes urban development outcomes across European cities. In Ireland, conservation of the built heritage is a key part of the planning framework, albeit one that is, in comparative terms, only recently established. While it is widely recognized that the underlying rationale for conservation of built heritage varies considerably (from cultural priorities to place marketing), the literature suggests that heritage and conservation professionals perform a key role in controlling decision-making through an official or “authorized” heritage discourse (AHD), emphasizing expert values and knowledge and based around selective heritage storylines often reflecting elite tastes. Drawing on policy and practice in Ireland, in this paper, we contribute to these debates by further unpacking the AHD, exploring tensions within the heritage policy elite through examination of competing views and representations relating to the purpose of built heritage protection. Based on a discourse analysis following interviews with key national actors, we identify two key narratives—a “museum-curatorial” discourse and an “inclusive heritage” discourse—which in turn frame conservation practices. We argue that subtle variations of heritage meanings have the potential to either reproduce (museum-curatorial discourse) or challenge (inclusive heritage discourse) conventional modes of practice, particularly relating to the relationship between built heritage and identity and the role of public engagement.     

Linking Heritage Preservation and Community Development: An Assessment of Grassroots Heritage Based Projects as Vehicles for Socio-Economic Development and Sustainable Heritage Preservation in Zimbabwe

This paper engages the practical aspects of linking heritage, in particular, archaeological heritage, with both individual and community economic development. In recent years, there has been growing realisation that culture, inclusive of cultural heritage, can be both a driver and an enabler of economic development, especially in developing countries. However, few documented examples demonstrate the validity of such arguments. The paper explores some practical examples of how, at the grassroots level, individuals and communities are attempting to exploit archaeological heritage sites as well as other cultural and natural heritage resources for income generation in Zimbabwe. The major thrust of the paper is to assess the manner of use and the viability of such ventures. Since the ability of archaeological heritage to generate revenue and support people around the sites has a direct effect on long-term survival of such heritage, ultimately, the paper contributes to the discourse on linking heritage and economic development as well as the theme of sustainable heritage preservation.
