The regulation of scientific and archaeological diving is complex but it is essential that underwater archaeologists are familiar with the requirements placed on them by legal systems. This paper outlines the history and development of current legal systems in four jurisdictions: the UK, USA, EU and Australia. This historical and legal approach informs key discussions facing maritime archaeologists; reference is made to training requirements, safety records and the question of who should be allowed to participate and who should be excluded from archaeological diving.  相似文献

This article revisits democratic engagement in post-war Britain in a context of debates about political disaffection in the current period. The study systematically reanalysed volunteer writing in the Mass Observation Archive and represents a significant methodological advance on previous studies. Little evidence was found to support common existing interpretations: whether ‘golden age’ narratives of deference to authority, partisan alignment and high voter turnout or revisionist accounts of apathy. Instead, evidence was found of something akin to what Hibbing and Theiss-Morse call ‘stealth democracy’. Citizens thought democracy to be important and felt a duty to vote, but wished for government by experts in the national interest. This ‘stealth’ interpretation builds on existing studies of duty, populism and expertise in twentieth-century Britain. It helps to move discussion of democratic engagement after the Second World War beyond the binaries of self/collective and private/public, and to explain the paradox of high voter turnout in a context of hostility to party politics. It also promises to inform debates about declining political support in the current period.  相似文献

Historians of early-modern poverty have emphasized the ways in which the poor ‘made shift’, reducing or even preventing their dependence on formal poor relief. This article looks at one aspect of that ‘economy of makeshifts’: the casual support of the poor by their neighbours. It uses evidence from a uniquely extensive archive of pauper petitions from Lancashire (1626–1710), many of which contain incidental information about strategies of making shift. The petitions suggest that neighbourly support for the needy was common in Lancashire, both through localized begging and in more stable supportive relationships. Nonetheless, the charity of neighbours could easily be exhausted, leaving those in poverty forced to call upon the more formalized support of the Poor Law.  相似文献

This paper extends theoretical and empirical debates on knowledge transfer practices in geographically dispersed project teams using a range of communications media. It presents quantitative data comparing work interactions between dispersed and co-located teams in five international, project-based firms. It shows that contrary to conventional wisdom, their respective practices are similar for many work activities such as search and routine information exchange. However dispersed team members validate, verify and consult differently to the respective co-located teams. Qualitative data from interviews and observation then illustrates typical interactions using the differing means and media available to the observed project teams, such as task decomposition and emergency corrective work. Due to an unfortunate oversight one of the references in this article is incomplete. It can be found here.  相似文献
