Patterns of political ideology and security policy

Recent studies on political ideology suggest the existence of partisan divides on matters of foreign and security policy, challenging the notion that "politics stops at the water's edge." However, when taken as a whole, extant work provides decidedly mixed evidence of party-political differences outside domestic politics. This article first conducts a systematic empirical analysis of the relationship between parties' left-right positions and their general attitude toward peace and security missions, which suggests that right-leaning parties tend to be more supportive of military operations. Yet, the results also show that the empirical pattern is curvilinear: centrist and center-right parties witness the highest level of support for military missions, while parties on both ends of the political spectrum show substantially less support. The second part of our analysis examines whether the stronger support of rightist parties for peace and security missions translates into a greater inclination of right-wing governments to actually deploy forces for military operations. Strikingly, our results suggest that leftist governments were actually more inclined to participate in operations than their right-leaning counterparts. The greater willingness of left-wing executives to deploy military forces is the result of their greater inclination to participate in operations with inclusive goals

Parliaments in security policy: involvement, politicisation, and influence

While parliaments have long been neglected actors in the analysis of security policy, recent studies indicate a slowly growing research literature on the subject. This introduction to a special issue on parliaments in security policy critically reviews this literature. It argues that current research is focused primarily on how parliaments, relying on formal legal competences, can constrain governmental policies and that this research needs expansion in three areas. First, informal sources of parliamentary influence on security policy deserve more systematic attention as the significance of parliaments in concrete cases often hinges on contextual factors and individual decision-makers. Secondly, we still lack a systematic understanding of the effects of parliamentary involvement on security policy and especially broader patterns that would be discernible across a wider variety of countries and policies. Finally, the role of parliaments for the politics of security is almost completely uncharted territory so far. When parliaments become involved in security policy, does this foster transparency and contribute to the politicization of security policy so that security policy becomes a “normal” political issue? The article reviews current research, derives findings from the contributions to this special issue, and spells out their wider implications for the study of domestic politics and international relations, before concluding with some avenues for future research

Parlamente in der Friedens- und Sicherheitspolitik: parlamentarische Kontrolle von Streitkräfteeinsätzen im Licht der Forschung

Since the 1990s, parliaments in many democracies have become more involved in the formulation and implementation of security policy. A growing number of studies in comparative politics and international relations address this phenomenon and examine the role of parliaments in decisions on war and peace, particularly on the deployment of military forces. This article reviews and summarizes this research and identifies three major trends in recent contributions. Research increasingly moves beyond a focus on formal competences and the right of parliaments to veto deployments, beyond treating parliaments as unitary actors, and beyond an exclusive focus on individual national parliaments

Developmental regulation of mitochondrial apoptosis by c-Myc governs age- and tissue-specific sensitivity to cancer therapeutics

It is not understood why healthy tissues can exhibit varying levels of sensitivity to the same toxic stimuli. Using BH3 profiling, we find that mitochondria of many adult somatic tissues, including brain, heart, and kidneys, are profoundly refractory to pro-apoptotic signaling, leading to cellular resistance to cytotoxic chemotherapies and ionizing radiation. In contrast, mitochondria from these tissues in young mice and humans are primed for apoptosis, predisposing them to undergo cell death in response to genotoxic damage. While expression of the apoptotic protein machinery is nearly absent by adulthood, in young tissues its expression is driven by c-Myc, linking developmental growth to cell death. These differences may explain why pediatric cancer patients have a higher risk of developing treatment-associated toxicities

The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey

The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS project includes 535,995 new galaxy spectra (median z=0.52), 102,100 new quasar spectra (median z=2.32), and 90,897 new stellar spectra, along with the data presented in previous data releases. These spectra were obtained with the new BOSS spectrograph and were taken between 2009 December and 2011 July. In addition, the stellar parameters pipeline, which determines radial velocities, surface temperatures, surface gravities, and metallicities of stars, has been updated and refined with improvements in temperature estimates for stars with T_eff<5000 K and in metallicity estimates for stars with [Fe/H]>-0.5. DR9 includes new stellar parameters for all stars presented in DR8, including stars from SDSS-I and II, as well as those observed as part of the SDSS-III Sloan Extension for Galactic Understanding and Exploration-2 (SEGUE-2). The astrometry error introduced in the DR8 imaging catalogs has been corrected in the DR9 data products. The next data release for SDSS-III will be in Summer 2013, which will present the first data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) along with another year of data from BOSS, followed by the final SDSS-III data release in December 2014.Comment: 9 figures; 2 tables.

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.
