From 1995 to 2015, Ecuador experienced one of its longest periods of deep political, social and economic crisis. During this interval, three democratically elected governments (Bucaram, 1997; Mahuad, 2000 and Gutiérrez, 2005) were overthrown and a critical juncture arose in 2006 as a result. Since 2007, and as a consequence of these chaotic circumstances, new populist strongmen ascended and, amid the biggest bonanza of oil revenues in Ecuadorian history, established a defective democracy. The gradual escalation of authoritarian tendencies during the three consecutive terms in which Rafael Correa has acted as President, have resulted in the severe weakening of the country’s democratic institutions, since Correa’s has strived to perpetuate himself in power through continual re-election into office, instead of building an institutional quality-democracy. This study aims to clarify the historical foundations of the recurrence of caudillistas, populist and authoritarian governments in Ecuador, revealing the basis of the specific path dependence of Ecuadorian politics. We also explore the Jungian theory, specifically the “pseudo-hero myth”, as the political narrative which Correa’s regime successfully employed to establish its hegemony. Additionally, we perform a psychological-political case analysis by examining the social psychology components underlying the Ecuadorian path dependence towards authoritarian and populist caudillos: Specifically, our case study is framed within historical institutionalism, which focuses on methodological individualism to attend various political science and psychological-political theories...

Context. 1ES 1011+496 (z = 0.212) was discovered in very high-energy (VHE, E >100 GeV) γ rays with MAGIC in 2007. The absence of simultaneous data at lower energies led to an incomplete characterization of the broadband spectral energy distribution (SED). Aims. We study the source properties and the emission mechanisms, probing whether a simple one-zone synchrotron self-Compton (SSC) scenario is able to explain the observed broadband spectrum. Methods. We analyzed data in the range from VHE to radio data from 2011 and 2012 collected by MAGIC, Fermi-LAT, Swift, KVA, OVRO, and Metsähovi in addition to optical polarimetry data and radio maps from the Liverpool Telescope and MOJAVE. Results. The VHE spectrum was fit with a simple power law with a photon index of 3.69 ± 0.22 and a flux above 150 GeV of (1.46±0.16)×10^(−11) ph cm^(−2) s^(−1) . The source 1ES 1011+496 was found to be in a generally quiescent state at all observed wavelengths, showing only moderate variability from radio to X-rays. A low degree of polarization of less than 10% was measured in optical, while some bright features polarized up to 60% were observed in the radio jet. A similar trend in the rotation of the electric vector position angle was found in optical and radio. The radio maps indicated a superluminal motion of 1.8 ± 0.4 c, which is the highest speed statistically significant measured so far in a high-frequency-peaked BL Lac. Conclusions. For the first time, the high-energy bump in the broadband SED of 1ES 1011+496 could be fully characterized from 0.1 GeV to 1 TeV, which permitted a more reliable interpretation within the one-zone SSC scenario. The polarimetry data suggest that at least part of the optical emission has its origin in some of the bright radio features, while the low polarization in optical might be due to the contribution of parts of the radio jet with different orientations of the magnetic field with respect to the optical emission.
