Defining 'underwater cultural heritage'

The newly adopted United Nations Education, Scientific and Cultural Organization's Convention on the Protection of the Underwater Cultural Heritage provides the first universal protection regime for this value archaeological resource. A central difficulty in concluding this Convention was defining underwater cultural heritage. This article considers the development of the definition agreed upon and analyses its utility in providing for a pragmatic and effective protection regime.

EMPIRICAL POLYCENTRICITY: THE COMPLEX RELATIONSHIP BETWEEN EMPLOYMENT CENTERS

Our paper empirically demonstrates that employment subcenters in large urban areas have important economic relationships with each other, and not solely with the central business district (CBD). Using data from Houston, Texas, we estimate polycentric density functions and show that “total” gradients differ from gradients using only own‐center coefficients. We model asymmetry by showing density is very different for centers with overlapping areas of influence. We conclude that subcenters have important yet heterogeneous linkages to each other in addition to the CBD, and that therefore the polycentric city is more complex than simply having additional centers mimicking the CBD.     

‘Nuclear Sword of the Moslem World’?: the United States,Britain, Pakistan,and the ‘Islamic Bomb’, 1977–80

There exists today considerable fear of nuclear proliferation across the ‘Islamic world.’ Despite this, an issue that - in part - set the tone for contemporary debates has largely gone under-examined in the scholarly literature. The emergence of the ‘Islamic bomb’ idea in the late 1970s created a meme that remains with us today. Analysing the roots of this meme allows us to examine its creation and the attitudes of governments towards this alleged emergent nuclear-proliferation threat. This analysis demonstrates that while the media portrayed the ‘Islamic world’ as violent, undifferentiated, and determined to gain nuclear capability, the US and British governments assessed matters evidentially and came to the conclusion that the ‘Islamic bomb’ represented a propaganda problem rather than an imminent nuclear-proliferation concern. Attitudes towards the ‘Islamic bomb’ highlight media and governmental attitudes towards the changing power balances in the Middle East and South Asia during a turbulent and troubled period.
