Current, emerging and future technologies for sensing the environment
This paper reviews current technologies that are used for environmental monitoring, and presents emerging technologies that will dramatically improve our ability to obtain spatially distributed, real-time data about key indicators of environmental quality at specific locations. Futuristic approaches to environmental monitoring that employ fundamental breakthroughs in materials science to revolutionise the way we monitor our environment will also be considered. In particular, approaches employing biomimetic and 'adaptive'/'stimuli-responsive' materials will be highlighted, as these could play an important role in the realization of small, low power, low cost, autonomous sensing and communications platforms that could form the building blocks of the much vaunted environmental 'sensor web'
The End of the Third Wave and the Global Future of Democracy. IHS Political Science Series No. 45, July 1997
The “Third Wave” of global democratization, which began in 1974, now appears to be drawing to a close. While the number of “electoral democracies” has tripled since 1974, the rate of increase has slowed every year since 1991 (when the number jumped by almost 20 percent) and is now near zero. Moreover, if we examine the more demanding standard of “liberal democracy” – in which there is substantial individual and associational freedom, civic pluralism, civi lian supremacy over the military, a secure rule of law, and “horizontal accountability” of office-holders to one another – we observe today the same proportion of liberal democracies in the world as existed in 1991. If a “third reverse wave” of democratic erosion or breakdowns is to be avoided, the new democracies of the third wave will need to become consolidated. Elites and citizens of every major party, interest, and ethnicity must accept the legitimacy of democracy and of the specific constitutional rules and practices in place in their country. In many new democracies, this requires a sweeping agenda of institutional reform to widen citizen access to power, control corruption, and improve the depth and quality of democracy. Elsewhere – as in China and Indonesia – rapid economic development and the gradual emergence of stronger, more autonomous civil associations and legal and representative institutions may be laying the foundations for a “fourth wave” of democratization at some point in the early twenty-first century
