Telepresence-enabled exploration of deep sea environments has developed over the past 30 years, providing access to archaeologists, scientists, and the general public to sites otherwise inaccessible due to depth. Pioneered through the inception of the JASON Project in the late 1980 s, telepresence missions have expanded to two dedicated ships of exploration, NOAA Ship Okeanos Explorer and exploration vessel Nautilus, and has been implemented on a series of opportunistic missions on other vessels. This paper chronicles the history of the use of telepresence for the exploration of shipwrecks in deep water as well as how this capability has allowed the public to engage with such missions. Broadening the scope of who can explore the deep sea, telepresence has also expanded what is observed and documented in the deep, which speaks to humanity’s use of the maritime world and an archaeology of discard through our material disposed of into the deep sea.  相似文献

The US–ROK alliance during the First Korean Nuclear Crisis provides the most likely case of high alliance cohesion. Curiously, however, instead of dancing to the American tune in their joint management of the Democratic People's Republic of Korea (DPRK) threat, the Republic of Korea (ROK) caused frequent policy collisions – supporting the US–DPRK negotiations at one point and opposing it at another – at the risk of jeopardizing its physical security. The main finding here is that the variations in the South Korean behavior were a function of their experience of status inconsistency. In particular, the ROK became compliant with the US–DPRK talks when it believed that its desired status marker of taking the leadership role in crisis management was within reach, and unyielding otherwise. These fluctuations ended up not only eroding the US–ROK alliance cohesion but also inhibiting a successful resolution of the crisis. All this bears directly on the fundamental question of whether international politics is to be understood in essentially realist terms.  相似文献

ABSTRACT

An amateur 1969 excavation at the Middle Archaic period Janulis site in Ontario unearthed the skeletal remains of three individuals and a dog. One of these, an adult female with an extensive offering, displayed several changes in the bones of her right arm and shoulder caused by the repetitive and intensive practice of an overhand throwing motion. The association of eight projectile points with her skeleton indicates that the activity was projectile throwing, suggesting a strong emphasis on hunting, normally a masculine role. She also had a turtle-shell rattle, an instrument usually associated with men in that time period. In contrast, the presence of two deer styliform bones in the burial point to a feminine role. These anomalies raise the possibility that this individual had adopted a nonbinary gender status, but the paucity of reliable comparative data makes it difficult to precisely define that status.  相似文献
