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

马家浜文化晚期陶鼎的兴起及其影响 总被引:1,自引:0,他引:1
环太湖地区马家浜文化晚期,形态各异的陶鼎开始兴起。各个类型陶鼎在时空分布、创制机理和发展过程等方面都存在着明显的不同,与本地区固有的以釜为主的炊器传统有着亲疏程度上的显著差异。不同制鼎传统之间彼此影响,关系错综复杂,一度形成了多个本土和外来传统并立的局面。厘清这些陶鼎类型的源流谱系,对于明确其后续影响,乃至阐释整个环太湖地区史前陶鼎传统的形成问题,都具有重要意义。 相似文献

城市空间快速扩张及郊区中心的崛起,带来多中心城市结构的演变及一系列城市问题。已有研究较少针对对郊区就业者的工作与通勤行为,未能全面地反映新职住“空间错位”。本文基于2012年对北京上地就业者的日常活动与出行调查数据得出以下结论:①主动郊区化的侧面通勤者体现出典型的郊区生活方式: “朝九晚六”、加班明显,生活活动空间更加广域化。②在郊区化过程中被动调整的逆通勤者职住距离最长、依赖公共交通通勤、“早出晚归”、错峰出行、生活活动空间呈现以家和工作地为主的“两极化”特征。③郊区中心内部相对职住接近的就地通勤者,在享受工作与通勤便利性(如职住接近、“晚出早归”)的同时活动空间高度隔离集中在郊区中心。 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

The Irish dimension of Anglo-American relations is a relatively marginalized aspect of the historiography of transatlantic studies. Historians have focused on the role of the Clinton administration in the Northern Ireland “peace process” but previous American contributions also warrant attention. As the Speaker of the United States House of Representatives, Thomas P. “Tip” O’Neill was one of the most prominent Irish-American politicians. This article demonstrates O’Neill's attempts to ensure that the American contribution to the Anglo-Irish process steadily increased, despite the transition from arguably his natural political ally in the President Jimmy Carter administration to President Ronald Reagan in 1981. O’Neill's interest in Northern Ireland and position as speaker helped ensure that Carter's promise of financial aid to Northern Ireland in 1977 following progress in the political process was fulfilled in March 1986. 相似文献
