The biogeography of islands is often strongly influenced by prior geological events. Corucia zebrata (Squamata: Scincidae) is endemic to the geologically complex Solomon Archipelago in Northern Melanesia. We examined the level of divergence for different island populations of C. zebrata and discussed these patterns in light of Pleistocene land bridges, island isolation, and island age. Corucia ...
We present results from three acceptability judgement experiments investigating the effect of discourse linking (d-linking) and animacy on whether-islands and interactions with resumption in Greek and English. Based on Anagnostopoulou’s referentiality hierarchy, we test the acceptability of four types of wh-phrases, what, what X, which X, which of X in a range of configurations (simple question...
This paper presents the results of a feasibility study of potential wind energy developments on the islands of New England. The study included the compilation of an inventory of New England coastal islands, a categorization of the islands according to energy related criteria, and an overview of the current energy supply situation on those islands where energy demanding activities take place. Th...
Acquisition of genomic islands plays a central part in bacterial evolution as a mechanism of diversification and adaptation. Genomic islands are non-self-mobilizing integrative and excisive elements that encode diverse functional characteristics but all contain a recombination module comprised of an integrase, associated attachment sites and, in some cases, a recombination directionality factor...
We describe in this Letter the first measurement of multiple islands in the core of a reversed field pinch (RFP). These islands appear with current profile modification leading to magnetic fluctuation reduction in the Madison symmetric torus RFP. Magnetic island widths decrease to an unprecedented level, reducing the overlap of adjacent islands and allowing distinct islands to appear. The struc...
Islands are divided according to their phase space structure—resonant islands and tangle islands are considered. It is proved that in the near-integrable limit these correspond to two distinct sets, hence that in general their definitions are not trivially equivalent. It is demonstrated and proved that accelerator modes of the standard map and of the web map are necessarily of the tangle island...
How much corruption is there in the Pacific islands? A review of different approaches to measurement
Pacific Economic Bulletin Volume 24 number 1 2009 © the australian national university New ways of measuring corruption are being used to assess the performance of governments in tackling the problem. The Pacific Islands Plan, for example, envisages a ‘control of corruption (integrity) indicator’ that could be used to assess a government’s progress towards achieving good governance (Pacific Isl...
Deposition of manganese onto the gallium-rich, nitrogen-polar GaN(000 1) surface results in the formation of quantum-height island structures. Two unique island heights differing by one atomic layer are observed, including 0.93 nm high islands which are unstable against the formation of 1.13 nm high islands. A row structure at the islands’ surface suggests a mixture of Mn and Ga, while growth o...
We propose a self-assembling procedure for the fabrication of GaAs islands by Droplet Epitaxy on silicon substrate. Controlling substrate temperature and amount of supplied gallium is possible to tune the base size of the islands from 70 up to 250 nm and the density from 10(7) to 10(9) cm(-2). The islands show a standard deviation of base size distribution below 10% and their shape evolves chan...
Large-scale resistive Hall-magnetohydrodynamic simulations of the transition from Sweet-Parker (collisional) to Hall (collisionless) magnetic reconnection are presented; the first to separate secondary islands from collisionless effects. Three main results are described. There exists a regime with secondary islands but without collisionless effects, and the reconnection rate is faster than Swee...
