The essays in Nationalizing Empires challenge the dichotomy between empire and nation state that for decades has dominated historiography. The authors center their attention on nation-building in the ...imperial core and maintain that the nineteenth century, rather than the age of nation-states, was the age of empires and nationalism. They identify a number of instances where nation building projects in the imperial metropolis aimed at the preservation and extension of empires rather than at their dissolution or the transformation of entire empires into nation states. Such observations have until recently largely escaped theoretical reflection.
The field of sustainable polymers is growing and evolving at unprecedented rates. Researchers are increasingly concerned with the feedstock origins and the degradation behavior of, especially, ...large-scale commodity packaging plastics. A perspective is offered here for the design of sustainable polymers, specifically addressing opportunities for monomer development and polymer degradation. Key concepts include: water degradability instead of biodegradability; incorporation of novel main-chain functionality, such as acetals; utilization of lignin-based aromatics; and direct polymerization of biogenic C1 feedstocks.
Thirteen essays by scholars from seven countries discuss the political use and abuse of history in the recent decades with particular focus on Central and Eastern Europe (Hungary, Poland, Estonia, ...Moldova, Ukraine, Russia as case studies), but also includes articles on Germany, Japan and Turkey, which provide a much needed comparative dimension. The main focus is on new conditions of political utilization of history in post-communist context, which is characterized by lack of censorship and political pluralism. The phenomenon of history politics became extremely visible in Central and Eastern Europe in the past decade, and remains central for political agenda in many countries of the regions. Each essay is a case study contributing to the knowledge about collective memory and political use of history, offering a new theoretical twist. The studies look at actors (from political parties to individual historians), institutions (museums, Institutes of National remembrance, special political commissions), methods, political rationale and motivations behind this phenomenon.
We report on observations of GRB 080503, a short gamma-ray burst (GRB) with very bright extended emission (about 30 times the gamma-ray fluence of the initial spike) in conjunction with a thorough ...comparison to other short Swift events. In spite of the prompt-emission brightness, however, the optical counterpart is extraordinarily faint, never exceeding 25 mag in deep observations starting at ~1 hr after the Burst Alert Telescope (BAT) trigger. The optical brightness peaks at ~1 day and then falls sharply in a manner similar to the predictions of Li & Paczynski (1998) for supernova-like emission following compact binary mergers. However, a shallow spectral index and similar evolution in X-rays inferred from Chandra observations are more consistent with an afterglow interpretation. The extreme faintness of this probable afterglow relative to the bright gamma-ray emission argues for a very low density medium surrounding the burst (a 'naked' GRB), consistent with the lack of a coincident host galaxy down to 28.5 mag in deep Hubble Space Telescope imaging. The late optical and X-ray peak could be explained by a slightly off-axis jet or by a refreshed shock. Our observations reinforce the notion that short GRBs generally occur outside regions of active star formation, but demonstrate that in some cases the luminosity of the extended prompt emission can greatly exceed that of the short spike, which may constrain theoretical interpretation of this class of events. This extended emission is not the onset of an afterglow, and its relative brightness is probably either a viewing-angle effect or intrinsic to the central engine itself. Because most previous BAT short bursts without observed extended emission are too faint for this signature to have been detectable even if it were present at typical level, conclusions based solely on the observed presence or absence of extended emission in the existing Swift sample are premature.
