'Glocal' disorder: causes, conduct and consequences of the 2008 Greek unrest

This article examines the unrest that emanated in Athens and rolled out across Greek cities in December 2008 as a case through which to advance understanding of how local, national and international arenas may together shape localised episodes of disorder. We begin by addressing the proximate and structural causes of the unrest, before turning to explore the multifarious character of protest actions, including novel and derivative forms of contestation deployed by protestors, and public debate about the appropriate apportioning of blame amongst the variety of actors involved. Finally, we look at the diverse outcomes of the unrest and their impact upon extant socio-political tensions. For each stage of the lifecycle of the unrest, we evaluate the relevance of international actors, practices and discourses. Our analysis of the Greek unrest of 2008 suggests, first, that the array of intersections between global, national and local dimensions of unrest are more diverse than has heretofore been recognised by pertinent scholarship; and second, that international or transnational factors may play a significant role in the emergence, conduct and consequences of disorder even in instances where national and local dynamics remain predominant

VUV Study of Electron Impact Dissociative Excitation of Thymine

Dissociative excitation of thymine following electron impact was studied in the energy range up to 430 eV. Emissions in the vacuum ultra-violet spectral region below 150 nm were studied and found to be dominated by the hydrogen Lyman series. Emission cross section data reveal that Lyman-α excitation displays a broad maximum at an electron impact energy of 160 eV. The probability of extracting other excited atoms from the parent molecule is found to be insignificant. Possible excitation and dissociation mechanisms in the parent molecule are discussed

Production of O(1D) following electron impact on CO2

We have studied the excitation of metastable O(1D) following dissociative excitation of CO2 in the electron impact energy range from threshold to 400 eV. A solid Ne matrix at ∼20 K forms the heart of the detector. This is sensitive to the metastable species through the formation of excited excimers (NeO*), The resultant excimer radiation is readily detected, providing a means of measuring the production of the metastables. Using a pulsed electron beam and time-of-flight techniques, we have measured the O(1D) kinetic energy spectrum and its relative production cross sections as a function of electron impact energy. Threshold energy data are used to gain information about the excitation channels involved. In addition, an emission excitation function for the red photons, emitted in coincidence with the exciting electron pulse, has been measured in the 0–400 eV energy range
