    Repression and reduction: the apparatchik\u27s discourse in the works of Ammianus Marcellinus, Denis Diderot, Victor Serge and George Orwell

    In monopolizing political power, the state claims to possess the best idea towards leading a society and solving its problems. While these claims may vary according to regime, all face the eventual failure of expectation on the part of its subjects. No regime can master all the variables in running the country, and so it must convince their subjects otherwise of its legitimacy, despite the reality of their failure. The apparatchik’s discourse is the interaction of the state’s discourse and that of its institutions. This discourse is used to uphold the state’s legitimacy through the expertise of its institutions. The most insidious application of this involves attacking dissidents who point out the state’s failure. Paul Ricoeur, in his work on character and identity, demonstrated the tension between two halves of human personality, the ipse, which is initiated by the self, and the idem, by society. The apparatchik’s discourse can attack this ipse and try to reduce the dissident to a state derived idem. Thus the discourse becomes a weapon in the struggle between the state and the dissident. This dissertation examines the apparatchik’s discourse through the works of four authors, Victor Serge’s Ville Conquise, S’il est minuit dans le siècle, and L’affaire Toulaév, Ammianus Marcellinus’ Res Gestae, Denis Diderot’s Essai sur la vie de Sénèque and Essai sur les règnes de Claude et de Néron, and George Orwell’s Burmese Days, Homage to Catalonia, Animal Farm and Nineteen Eighty-Four. Despite the differences in time and culture, a thread runs through their works that reveals a continuous form in this discourse in political activity and, more importantly, in the lives of individual people. Despite this similarity, there is an important degree of difference between these works. Some texts explore the discourse as a means of understanding political activity and its role in human lives, while others use it both to destroy and uphold specific people. Lastly, some try to banish the discourse completely. Through these similarities and differences, this study will explore the use, abuse, and impact of the apparatchik’s discourse on representations of the individual

    The Prospect of the Russian Language in Georgia. Insights from the Educated Youth

    Get PDF
    After the collapse of the Soviet Union, the status of the Russian language in the new-born Republics became a central issue. In the Southern Caucasus, all the Constitutions promulgated by the three Republics opted for ethnocentric language policies that accepted the titular language as the only State Language. However, the role of the Russian language as a lingua franca remained crucial for international communication and everyday interaction. It followed that it continued to play an important role also in education. The present study focuses on Georgia, where a strong derussification policy has taken place in the last decades and aims at understanding to what extent the use of Russian among the young generations has contracted. In particular, we present an analysis conducted on data collected via (i) a survey for young people consisting of questions on their sociolinguistic background and a proficiency test in Russian, and (ii) semi-structured interviews for teachers of Russian and English as Foreign Languages on the research topics

    The molecular gas in Luminous Infrared Galaxies II: extreme physical conditions, and their effects on the X_{co} factor

    Full text link
    In this work we conclude the analysis of our CO line survey of Luminous Infrared Galaxies (LIRGs: L_{IR}>=10^{11}L_{sol}) in the local Universe (Paper\,I), by focusing on the influence of their average ISM properties on the total molecular gas mass estimates via the so-called X_{co}=M(H_2)/L_{co,1-0} factor. One-phase radiative transfer models of the global CO Spectral Line Energy Distributions (SLEDs) yield an X_{co} distribution with: \sim(0.6+/-0.2) M_{sol}(K km s^{-1} pc^2)^{-1} over a significant range of average gas densities, temperatures and dynamical states. The latter emerges as the most important parameter in determining X_{co}, with unbound states yielding low values and self-gravitating states the highest ones. Nevertheless in many (U)LIRGs where available higher-J CO lines (J=3--2, 4--3, and/or J=6--5) or HCN line data from the literature allow a separate assessment of the gas mass at high densities (>=10^{4} cm^{-3}) rather than a simple one-phase analysis we find that {\it near-Galactic X_{co} (3-6)\, M_sol\,(K\,km^{-1}\,pc^2)^{-1} values become possible.} We further show that in the highly turbulent molecular gas in ULIRGs a high-density component will be common and can be massive enough for its high X_{co} to dominate the average value for the entire galaxy. ......... ...this may have thus resulted to systematic underestimates of molecular gas mass in ULIRGs.Comment: 77 pages, 6 figures, one Table, accepted for publication at The Astrophysical Journa

    Radio source feedback in galaxy evolution

    Full text link
    We present a galaxy evolution model which incorporates a physically motivated implementation of AGN feedback. Intermittent jets inflate cocoons of radio plasma which then expand supersonically, shock heating the ambient gas. The model reproduces observed star formation histories to the highest redshifts for which reliable data exists, as well as the observed galaxy colour bimodality. Intermittent radio source feedback also naturally provides a way of keeping the black hole and spheroid growth in step. We find possible evidence for a top-heavy Initial Mass Function (IMF) for z>2z>2, consistent with observations of element abundances, and sub-mm and Lyman break galaxy counts.Comment: 37 pages, 14 figures, ApJ (in press

    The Star Formation and Nuclear Accretion Histories of Normal Galaxies in the AGES Survey

    Full text link
    We combine IR, optical and X-ray data from the overlapping, 9.3 square degree NOAO Deep Wide-Field Survey (NDWFS), AGN and Galaxy Evolution Survey (AGES), and XBootes Survey to measure the X-ray evolution of 6146 normal galaxies as a function of absolute optical luminosity, redshift, and spectral type over the largely unexplored redshift range 0.1 < z < 0.5. Because only the closest or brightest of the galaxies are individually detected in X-rays, we use a stacking analysis to determine the mean properties of the sample. Our results suggest that X-ray emission from spectroscopically late-type galaxies is dominated by star formation, while that from early-type galaxies is dominated by a combination of hot gas and AGN emission. We find that the mean star formation and supermassive black hole accretion rate densities evolve like (1+z)^3, in agreement with the trends found for samples of bright, individually detectable starburst galaxies and AGN. Our work also corroborates the results of many previous stacking analyses of faint source populations, with improved statistics.Comment: 19 pages, 15 figures, 3 tables, accepted for publication in Ap

    The DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation

    Get PDF
    Over the next 5 yr, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4 m Mayall Telescope at Kitt Peak National Observatory to conduct the first Stage IV dark energy galaxy survey. At z 10 million galaxies spanning 14,000 deg2 . In this work, we present and validate the final BGS target selection and survey design. From the Legacy Surveys, BGS will target an r 80% fiber assignment efficiency. Finally, BGS Bright and BGS Faint will achieve >95% redshift success over any observing condition. BGS meets the requirements for an extensive range of scientific applications. BGS will yield the most precise baryon acoustic oscillation and redshift-space distortion measurements at z < 0.4. It presents opportunities for new methods that require highly complete and dense samples (e.g., N-point statistics, multitracers). BGS further provides a powerful tool to study galaxy populations and the relations between galaxies and dark matter

    Frequently asked questions about chlorophyll fluorescence, the sequel

    Get PDF
    [EN] Using chlorophyll (Chl) a fluorescence many aspects of the photosynthetic apparatus can be studied, both in vitro and, noninvasively, in vivo. Complementary techniques can help to interpret changes in the Chl a fluorescence kinetics. Kalaji et al. (Photosynth Res 122: 121-158, 2014a) addressed several questions about instruments, methods and applications based on Chl a fluorescence. Here, additionalChl a fluorescence-related topics are discussed again in a question and answer format. Examples are the effect of connectivity on photochemical quenching, the correction of F-V/F-M values for PSI fluorescence, the energy partitioning concept, the interpretation of the complementary area, probing the donor side of PSII, the assignment of bands of 77 K fluorescence emission spectra to fluorescence emitters, the relationship between prompt and delayed fluorescence, potential problems when sampling tree canopies, the use of fluorescence parameters in QTL studies, the use of Chl a fluorescence in biosensor applications and the application of neural network approaches for the analysis of fluorescence measurements. The answers draw on knowledge fromdifferent Chl a fluorescence analysis domains, yielding in several cases new insights.Kalaji, H.; Schansker, G.; Brestic, M.; Bussotti, F.; Calatayud, A.; Ferroni, L.; Goltsev, V....
