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

Accountability of representatives to electors is a key indicator of democratic health. In mixed-member systems, the coexistence of two kinds of representation provides the opportunity to test competing claims with minimal confounding factors. There is debate about the relative accountability of constituency and list MPs, and in particular, concerning dual candidacy, where individuals can stand for both constituency and list seats. Analysing New Zealand elections since 1999, with comparisons back to the previous single-member plurality system, this article examines the effects of dual candidacy, legislative turnover and the cases where constituency or electorate MPs have lost their seats, but remained in Parliament as list members.

代表对选民负责乃民主是否健康的一个关键指标。在混合成员制下,两类代表的共存为比较单纯地检验其竞争的主张提供了机会。不过,选区及名单议员的相对责任,尤其在一个个体可以既代表选区又代表名单席位的情况下的责任,对此是有争议的。本文分析了新西兰1999年以来的选举,并与之前的单一成员多数选举制做了对比,还考察了双重候选人制的效果、议员的流动、以及选区或议员落选但依然是国会名单成员的情况。  相似文献

Attempts to extend methods for dating archaeological bones beyond that of radiocarbon dating, such as amino acid racemization, have met with limited success owing to the dependence on multiple environmental factors and controls. Despite facing similar challenges, deamidation of glutamine has recently been investigated as a potential indicator of ‘thermal age' in archaeological bones, as well as a measure of their preservation quality. In this study, we undertook a series of simulated diagenetic experiments to understand the various factors affecting deamidation. Further, we analysed bones from different Middle Palaeolithic layers from Grotte Mandrin (France), with the results suggesting potential use of deamidation for relative dating, but only in case of extremely well‐preserved layers. The results also suggested the possible use of attenuated total reflectance‐Fourier transform infrared (ATR‐FTIR) spectroscopy as a screening test for soluble collagen before proteomic analysis.  相似文献

One of the main assumptions of the Ecology of Games Framework (EGF) is that governance processes are heavily affected by the interactions among policy actors that take place in multiple decision‐making forums, which often function interdependently. In this article, we use data collected in the Tampa Bay and California Delta water governance systems to examine how “biophysical interdependence”—the extent to which forums deal with interconnected policy problems—impacts the costs that actors face when they participate in forums, which in turn can affect their performance in them. Furthermore, we examine how the individual information exchange networks that actors have (i.e., their ego‐networks) can mediate the previous relationship. We find that actors with networks that have more closure are better able to mitigate the costs associated with participating in biophysically interdependent forums, thus leading to better in‐forum performance. Our findings shed new light on the relationship between structure and function in complex ecologies of games.  相似文献

Empowering backbench Members of Parliament in order to restore the effectiveness of the House of Commons has been a central theme in Canadian parliamentary reform for at least fifty years, but results are widely seen as disappointing. This article argues that unrealistic expectations, fostered by adherence to a traditional conception of the Westminster model of representative and responsible government, are part of the problem. A modernized conception of parliamentary government, recognizing the House as a forum for competing political parties between elections, could help us to better understand the House and improve its contribution to democratic governance. The proposed approach suggests innovative procedural options for legislative debate, Question Period, and other activities. It also offers a consistent basis for addressing issues such as floor-crossing, coalitions, and prorogations. More broadly, it points to the need for an integrated approach to the House, elections, political parties, public education, and citizen engagement in order to respond to contemporary democratic challenges.  相似文献

Abstract: This article, based upon in-depth interviews with anti-governmentleaders and activists, first explains the significance of theupheaval in Communist Poland in 1980–1981 and articulateshow the author became involved in this research and explainshis methodology. It then concentrates on the impact on the personallives of the participants and on social relations in Polandof the upheaval that produced an unprecedented-in-the-Soviet-blocindependent union with the right to strike. It shows how activistsdeveloped talents and cultivated abilities as they assumed responsibilitiesthat had previously been unavailable to them. It examines howworkers' lives changed as they grasped control of power: theirworking conditions improved; their status rose; they treatedone another better; they educated themselves. These changes,which contributed to the context in which the political struggleof that period took place, survived the suppression of the unionand ultimately contributed to bringing about the end of Communismin Poland.  相似文献

Previous studies of patterns of osteoarthritis involvement in prehistoric skeletal populations have been used to suggest differences in lifestyle or subsistence patterns. In spite of the intriguing nature of such studies, inadequate controls for the potential confounding effects of age have made results less secure than they appear. While researchers remain unable to control for the inherent limitations imposed by preservation bias, meaningful advancement could be made in the analysis of these data. Here we propose two methods from epidemiology that would allow more robust comparisons between populations with differing age-structures: age-adjustment and logistic regression. We apply these two methods to previously published data from prehistoric populations of the American Great Basin. In doing so, we are able to discern sex differences in risk for osteoarthritis at the shoulder (beta = −1.82, SE = 0.74, OR = 0.16, 95% CI = 0.04–0.69, p = 0.013), elbow (beta = −2.07, SE = 0.82, OR = 0.13, 95% CI = 0.03–0.63, p = 0.011), and in the foot (beta = −3.11, SE = 1.57, OR = 0.04, 95% CI = 0.00–0.97, p = 0.048), that were not noted in previous analyses of these data. These findings suggest that greater clarity of results and more precise comparisons of risk may be achieved by using these methods. We conclude that further application of these methods to bioarchaeological studies would potentially improve what can be said about prehistoric health patterns and lifeways.  相似文献
