Reality Shows in Chile, origin and road map. Historical-Communication Dialogues

Reality shows are TV programs which represent a format used in television nowadays; however, the observation practices of individual and/or group intimacy dates from thousands years ago. Sometimes this was driven by voyeurism or morbid fascination, some others, by the purpose of guarding, supervising and maintaining status quo. This work offers an alternative answer to the explanation of this type of TV program emergence and relates this appearance to a government procedure bound up with modern State terrorism which began at the end of the eighteenth century and has been recalled by different regimes until present days.

Oscillator strengths for transitions in C-like ions between K XIV and Mn XX

Energy levels and oscillator strengths (transition probabilities) have been calculated for transitions among 46 fine-structure levels of the (1s(2)) 2s(2) 2p(2), 2s2p(3),2p(4), 2s(2)2p3s, 2s(2) 2p3p and 2s(2)2p3d configurations of C-like K XIV, Sc XVI, Ti XVII, V XVIII, Cr XIX and Mn XX using the GRASP code. Configuration interaction and relativistic effects have been included while generating the wavefunctions. Calculated values of energy levels agree within 3% with the experimentally compiled results, and the length and velocity forms of oscillator strengths agree within 20% for a majority of allowed transitions.

Energy levels and radiative rates for transitions in Ar XIII, Ar XIV and Ar XV

Energies for 524 levels of Ar XIII, 460 levels of Ar XIV and 156 levels of Ar XV have been calculated using the GRASP code of Dyall et al. (1989). Additionally, radiative rates, oscillator strengths, and line strengths are calculated for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions among these levels. Comparisons are made with the limited results available in the literature, and the accuracy of the data is assessed. Our energy levels are estimated to be accurate to better than 1%, whereas results for other parameters are probably accurate to better than 20%. Additionally, the level lifetimes derived from our radiative rates are in excellent agreement with measured values.

Welfare Regimes and “progressive” governments in Latin America: The cases of Venezuela, Ecuador and Bolivia

Several authors have applied the concept of Welfare Regimens for studying social policy in Latin America (Esping-Andersen, 1993 and 2000). Among others, Martínez Franzoni (2007) develops a typology, with fi eld work is at the turn of the millennium, and establishes three categories: State-productivist regime, state-protectionist and family orientated. Most countries in the region are placed in the latter category. The hypothesis of this article argues that with the emergence of governments considered “left” or “progressive” in several countries of the region from the late ‘90s and, more decisively, in 2000’, the map of welfare regimes models could have mutated substantively. The nationally transformative experiences are different (various socio-economic realities and political action in which they are located exists) but they have several contact points that can be summarized in a greater state intervention in different areas previously closed to their operating and recovery of important functions of welfare and care of the population by the government. The paper discusses with an exploratory and descriptive approach the welfare schemes that would shape in three countries that have constitutionalized the change from the neoliberal paradigm: Venezuela, Bolivia and Ecuador.

Del Fichero supremo a la Biblioteca de Babel: Salaverría, precursor de Borges

A juzgar por alguna declaración más bien negativa de Borges sobre la literatura española, se podría creer que esta no influyó demasiado en él. Sin embargo, existen indicios de que pudo haberse inspirado también en determinados escritores españoles coetáneos hoy casi olvidados. Uno de ellos pudo ser José María Salaverría, entre cuyos relatos destaca “El fichero supremo” (1926), del que se ha dicho que “anticipa algunas de las preocupaciones características de un tipo de relato que Jorge Luis Borges elevará años después a la máxima categoría estética”. De hecho, recuerda a “La biblioteca de Babel” (1941) borgiana por su planteamiento hasta el punto de que podría pensarse que el maestro argentino pudo tener presente, a la hora de escribir esa obra maestra, ese cuento de Salaverría, el cual se publicó por primera vez en Caras y Caretas, una revista porteña que Borges reconoció “devorar” en su juventud. Sin embargo, el interés mayor de la comparación entre “El fichero supremo” y “La biblioteca de Babel” no radica tanto en el carácter de posible fuente del primero como en el contraste entre sus formas de presentación narrativa: desde fuera y en tercera persona en Salaverría, en un marco realista; y desde dentro y en primera persona, prácticamente sin marco, en Borges. Este parece desarrollar, en el registro propio de la “imaginación razonada” descrito por él mismo, una virtualidad presente en el relato de Salaverría, cuya comparación con “La biblioteca de Babel” puede suscitar también alguna reflexión sobre el enigma de la identidad y el carácter de la voz enunciadora de la biblioteca universal de Babel. Al menos, esta parece haber hecho realidad en cierto modo, de forma sublime, el patético sueño divino del archivero imaginado por Salaverría.

Energy levels, radiative rates and electron impact excitation rates for transitions in Si XII, Si XIII and Si XIV

In this paper, we report calculations of energy levels, radiative rates and electron impact excitation rates for transitions in Li-like Si XII, He-like Si XIII and H-like Si XIV. The grasp (general-purpose relativistic atomic structure package) is adopted for calculating energy levels and radiative rates, while for determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code (darc) is used. Oscillator strengths, radiative rates and line strengths are reported for all E1, E2, M1 and M2 transitions among the lowest 24 levels of Si XII, 49 levels of Si XIII and 25 levels of Si XIV, belonging to the n≤5 configurations. Collision strengths have been averaged over a Maxwellian electron velocity distribution and the effective collision strengths so obtained are reported over a wide temperature range below 107 K. Comparisons have been made with similar data obtained from the flexible atomic code (fac) to highlight the importance of resonances, included in calculations from darc, in the determination of effective collision strengths. Discrepancies between the collision strengths from darc and fac, particularly for weak transitions and at low energies, are also discussed. Additionally, lifetimes are listed for all calculated levels of the above three ions, although no measurements are available with which to compare.

Energy levels, radiative rates and electron impact excitation rates for transitions in Be-like Cl XIV, K XVI and Ge XXIX

Results for energy levels, radiative rates and electron impact excitation (effective) collision strengths for transitions in Be-like Cl XIV, K XVI and Ge XXIX are reported. For the calculations of energy levels and radiative rates the general-purpose relativistic atomic structure package is adopted, while for determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code is used. Oscillator strengths, radiative rates and line strengths are listed for all E1, E2, M1 and M2 transitions among the lowest 98 levels of the n ≤ 4 configurations. Furthermore, lifetimes are provided for all levels and comparisons made with available theoretical and experimental results. Resonances in the collision strengths are resolved in a fine energy mesh and averaged over a Maxwellian velocity distribution to obtain the effective collision strengths. Results obtained are listed over a wide temperature range up to 10^7.8 K, depending on the ion.

Energy levels, radiative rates and electron impact excitation rates for transitions in Fe XIV

Energies and lifetimes are reported for the lowest 136 levels of Fe XIV, belonging to the (1s(2)2s(2)2p(6)) 3s(2)3p, 3s(3)p(2), 3s(2)3d, 3p(3), 3s(3)p(3)d, 3p(2)3d, 3s(3)d(2), 3p(3)d(2) and 3s(2)4l configurations. Additionally, radiative rates, oscillator strengths and line strengths are calculated for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) transitions. Theoretical lifetimes determined from these radiative rates for most levels show satisfactory agreement with earlier calculations, a swell as with measurements. Electron impact excitation collision strengths are also calculated with the Dirac atomic R-matrix code (DARC) over a wide energy range up to 260 Ryd. Furthermore, resonances have been resolved in a fine energy mesh to determine effective collision strengths, obtained after integrating the collision strengths over a Maxwellian distribution of electron velocities. Results are listed for all 9180 transitions among the 136 levels over a wide range of electron temperatures, up to 10(7.1) K. Comparisons are made with available results in the literature, and the accuracy of the present data is assessed.
