Precedents, parliaments, and foreign policy:Historical analogy in the House of Commons vote on Syria

This analysis investigates the role of historical analogies in the influence that parliaments have in foreign policy. Our empirical focus is the UK Parliament’s unusual opposition to the Prime Minister on UK involvement in Syria in 2013. The vote challenges many conventional expectations about the role of parliament in security affairs. Important in this vote were lessons learned and strategically used from UK participation in the intervention of Iraq in 2003. This argument is developed theoretically based on research on historical analogies: parliaments, ‘learn’ (primarily negative) lessons about past foreign policy events which guide parliamentary preferences and procedures and can enhance parliaments’ role in subsequent foreign policy. The article contributes to research on analogies by extending the logic to lessons on process. This use of precedents can offer more structurally oriented perspectives that translate critical junctures into reforms in procedures and policy-making practices.</p

AGN STORM 2. VI. Mapping Temperature Fluctuations in the Accretion Disk of Mrk 817

We fit the UV/optical lightcurves of the Seyfert 1 galaxy Mrk 817 to produce maps of the accretion disk temperature fluctuations δ T resolved in time and radius. The δ T maps are dominated by coherent radial structures that move slowly (v ≪ c) inward and outward, which conflicts with the idea that disk variability is driven only by reverberation. Instead, these slow-moving temperature fluctuations are likely due to variability intrinsic to the disk. We test how modifying the input lightcurves by smoothing and subtracting them changes the resulting δ T maps and find that most of the temperature fluctuations exist over relatively long timescales (hundreds of days). We show how detrending active galactic nucleus (AGN) lightcurves can be used to separate the flux variations driven by the slow-moving temperature fluctuations from those driven by reverberation. We also simulate contamination of the continuum emission from the disk by continuum emission from the broad-line region (BLR), which is expected to have spectral features localized in wavelength, such as the Balmer break contaminating the U band. We find that a disk with a smooth temperature profile cannot produce a signal localized in wavelength and that any BLR contamination should appear as residuals in our model lightcurves. Given the observed residuals, we estimate that only ∼20% of the variable flux in the U and u lightcurves can be due to BLR contamination. Finally, we discus how these maps not only describe the data but can make predictions about other aspects of AGN variability
