Introduction

The public are engaging more with archaeology today than ever before, whether this is through the plethora of television channels increasing access to and providing reinterpretations of archaeological sites and finds, or through the blockbuster exhibitions hosted by museums (see Holtorf 2005, 2007). However are the public just expected to be consumers or should they be encouraged to participate and help direct the archaeological work being undertaken through active engagement?     

Our Privilege and Co-responsibility in the Protection of the Underwater Cultural Heritage

Mexico’s National Institute of Anthropology and History established an ethical program for the protection and research of the country’s underwater cultural heritage (UCH). Its Vice-Directorate of Underwater Archaeology trains archaeology and conservation students, participates in national and international initiatives regarding UCH, and develops multidisciplinary projects in maritime and continental waters. During negotiation of the UNESCO Convention, the Latin American and Caribbean Group united in a strong voice and contributed to its adoption in 2001; in 2006, Mexico ratified the Convention. This article highlights Mexico’s adoption of the 2001 UNESCO Convention as a case study, to stimulate all countries to ratify the convention and to cooperate in protecting the world’s UCH.     

South Carolina Shipyards: Labour,Logistics, Lumber and Ladies

Southern shipyards, like Hobcaw and Mars Bluff, were established at locations chosen primarily for convenient access to transportation networks, building materials, clientele and labour. The historical record reveals a home front role played by local plantation owners and slaves as shipyard labour. Women served as project fundraisers, shipyard dilettantes, shipwright’s wives and possibly slave mistresses with a paucity of material culture to confirm their presence in the archaeological record. Archaeological investigations on land and underwater yield evidence of artefacts associated with diet, shipbuilding, warfare and ethnicity.

3D numerical modeling of hydrothermal processes during the lifetime of a deep geothermal reservoir

Understanding hydrothermal processes during production is critical to optimal geothermal reservoir management and sustainable utilization. This study addresses the hydrothermal (HT) processes in a geothermal research doublet consisting of the injection well E GrSk3/90 and production well Gt GrSk4/05 at the deep geothermal reservoir of Groß Schönebeck (north of Berlin, Germany) during geothermal power production. The reservoir is located between ?4050 to ?4250 m depth in the Lower Permian of the Northeast German Basin. Operational activities such as hydraulic stimulation, production (T = 150°C; Q = ?75 m³ h^?1; C = 265 g l^?1) and injection (T = 70°C; Q = 75 m³ h^?1; C = 265 g l^?1) change the HT conditions of the geothermal reservoir. The most significant changes affect temperature, mass concentration and pore pressure. These changes influence fluid density and viscosity as well as rock properties such as porosity, permeability, thermal conductivity and heat capacity. In addition, the geometry and hydraulic properties of hydraulically induced fractures vary during the lifetime of the reservoir. A three‐dimensional reservoir model was developed based on a structural geological model to simulate and understand the complex interaction of such processes. This model includes a full HT coupling of various petrophysical parameters. Specifically, temperature‐dependent thermal conductivity and heat capacity as well as the pressure‐, temperature‐ and mass concentration‐dependent fluid density and viscosity are considered. These parameters were determined by laboratory and field experiments. The effective pressure dependence of matrix permeability is less than 2.3% at our reservoir conditions and therefore can be neglected. The results of a three‐dimensional thermohaline finite‐element simulation of the life cycle performance of this geothermal well doublet indicate the beginning of thermal breakthrough after 3.6 years of utilization. This result is crucial for optimizing reservoir management. Geofluids (2010) 10 , 406–421     

United States: Responses to the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage

While the US is not a signatory to the 2001 UNESCO Convention, much progress has been made by US agencies to implement its Rules and principles. The US signed an Agreement on Titanic with Rules that are nearly identical to the UNESCO Convention. US agencies have also expressed support for the Rules and their implementation into their programs. This paper identifies these positive actions as well as the two primary concerns that have prevented the US from signing the Convention to date: (1) “creeping coastal State jurisdiction” and (2) treatment of sunken state vessels.     

四、五世纪东亚世界的形成与东晋南朝——以中国史料为中心

Adopting the historical periodization and the “ethnic awakening” theory of Konan Naito, this essay discusses the early formation of East Asian states such as Koguryō, Paekche, Silla and Wa during the 4^th and 5^th centuries, as well as the political order within the East Asian society shaped by the enfeoffment of the Eastern Jin and the Southern dynasties by using Chinese sources. It argues that the cultural influences of the Qin and Han dynasties promoted the ethnic awakening of East Asian peoples, and during the turmoil periods of the Wei, the Jin, and the Division Era these ethnic groups leaped rapidly in their roads of state-formation. The enfeoffment system of the Eastern Jin played significant role in this process, and therefore set up the basic structure of the international relationship in early modern East Asia.     

明清的资讯传播、社会想像与公众社会

The flourishing development of media during the Ming and Qing eras affected the building of new methods of interpersonal interactions between an individual and society as well as between the people themselves. By virtue of media like Dibao 邸报 (court liaison reports), drama or novels, interpersonal interactions could reach beyond space and object restrictions. These media could thus rapidly spread particular or individual news to the general public, making those who were absent from the scene feel as if they were “experiencing” it, and at the same time allowing them to “participate in” social affairs beyond their knowledge. In this way, mass media surpassed the individual living sphere, ultimately forming a “public sphere.” Under the influence of these media, each individual could join this “public sphere” and be connected with the imagined “general public.” That is to say, mass media created an “imagined society.” In addition to a personal limited “real world,” there was an immense “fictitious world” for everyone to take part in and experience. Accordingly, interactions between people developed into interactions between each individual and the abstract society, which could cut across space limitations, and establish an immense “public society.”
