Protected areas are controversial because they are so important for conservation and because they distribute fortune and misfortune unevenly. The nature of that distribution, as well as the terrain of protected areas themselves, have been vigorously contested. In particular, the relationship between protected areas and poverty is a long-running debate in academic and policy circles. We review t...

I report on blogs as a “protected space” within the context of an ethnographic study that examined blogging from a “blogger’seye” view. I discuss the ability of bloggers to control the content of what is “broadcast” in their blogs and how this affects audience perception. I examine the use of blogs as a communicative medium as compared to alternative means of immediate social interaction. I dis...

Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of PAs on natural land cover within each of 147 countries by comparing outcomes inside PAs with outcomes outside. We use 'matching' (or 'apples to apples') for land characteristics...

The antibacterial drug ciprofloxacin (cfH) has been used to protect gold nanoparticles of two different mean diameters, 4 and 20 nm. The protection is complete with about 65 and 585 cfH molecules covering 4 and 15 nm particles, respectively. The nature of binding has been investigated by several analytical techniques. The nitrogen atom of the NH moiety of piperazine group binds on the gold surf...

Nanoparticles composed of functional materials hold great promise for applications due to their unique electronic, optical, magnetic, and catalytic properties. However, a number of functional materials are not only difficult to fabricate at the nanoscale, but are also chemically unstable in solution. Hence, protecting nanoparticles from corrosion is a major challenge for those applications that...

The notion of proprietary certificates [7] was recently introduced in an attempt to discourage sharing of access rights to subscription-based resources. A proprietary certificate is a certificate on a public key – the so-called proprietary key – that contains some information related to another (so-called collateral) certificate and has the property that if the owner of the proprietary public k...

In this report, we evaluate the present state of the rapidly emerging field of monolayer-protected cluster (MPC) molecules with regard to their synthesis and monolayer functionalization, their core and monolayer structure, their composition, and their properties. Finally, we canvass some of the important remaining research opportunities involving MPCs.

Air Traac Management (ATM) of the future allows for the possibility of free ight, in which aircraft choose their own optimal routes, altitudes, and velocities. The safe resolution of trajectory connicts between aircraft is necessary to the success of such a distributed control system. In this paper, we present a method to synthesize provably safe connict resolution maneuvers. The method models ...
