    The jet-disk symbiosis without maximal jets: 1D hydrodynamical jets revisited

    No full text
    In this work we discuss the recent criticism by Zdziarski (2016, A&A, 586, A18) of the maximal jet model derived in Falcke & Biermann (1995, A&A, 293, 665). We agree with Zdziarski that in general a jet’s internal energy is not bounded by its rest-mass energy density. We describe the effects of the mistake on conclusions that have been made using the maximal jet model and show when a maximal jet is an appropriate assumption. The maximal jet model was used to derive a 1D hydrodynamical model of jets in agnjet, a model that does multiwavelength fitting of quiescent/hard state X-ray binaries and low-luminosity active galactic nuclei. We correct algebraic mistakes made in the derivation of the 1D Euler equation and relax the maximal jet assumption. We show that the corrections cause minor differences as long as the jet has a small opening angle and a small terminal Lorentz factor. We find that the major conclusion from the maximal jet model, the jet-disk symbiosis, can be generally applied to astrophysical jets. We also show that isothermal jets are required to match the flat radio spectra seen in low-luminosity X-ray binaries and active galactic nuclei, in agreement with other works

    Dramatic Battles in Eighteenth-Century France Philosophes, Anti-Philosophes and Polemical Theatre

    No full text
    The mid-eighteenth century witnessed a particularly intense conflict between the Enlightenment philosophes and their enemies, when intellectual and political confrontation became inseparable from a battle for public opinion. Logan J. Connors underscores the essential role that theatre played in these disputes.This is a fascinating and detailed study of the dramatic arm of France’s war of ideas in which the author examines how playwrights sought to win public support by controlling every aspect of theatrical production – from advertisements, to performances, to criticism. An expanding theatre-going public was recognised as both a force of influence and a force worth influencing.By analysing the most indicative examples of France’s polemical theatre of the period, Les Philosophes by Charles Palissot (1760) and Voltaire’s Le Café ou L’Ecossaise (1760), Connors explores the emergence of spectators as active agents in French society, and shows how theatre achieved an unrivalled status as a cultural weapon on the eve of the French Revolution. Adopting a holistic approach, Connors provides an original view of how theatre productions ‘worked’ under the ancien régime, and discusses how a specific polemical atmosphere in the eighteenth century gave rise to modern notions of reception and spectatorship. Eighteenth-century specialists are well acquainted with the controversies surrounding the premieres of Charles Palissot's Les Philosophes and Voltaire's Le Caffé; ou, L'Écossaise at the Comédie-Française in 1760. […] Connors offers new perspectives on the conflict by delving deeply into the pamphlet literature and periodical reviews of the affair. For example, there is an insightful analysis of the short pamphlet Les Philosophes manqués by André-Charles Cailleau, written in the form of a play but never intended for the stage, which demonstrates how participants in the controversy appealed to both readers and spectators.[…] [T]his book is a welcome addition to recent interdisciplinary approaches to the interplay of public theatre and political culture in Old Regime and Revolutionary France.- French Studies Connors’s rich description of the political and personal calculations involved in Voltaire’s decision to enter the fray convincingly buttresses the argument that these plays assume a new genre identity by being mobilized for publicity purposes that far exceed the boundaries of the stage.- Ideas, Aesthetics, and Inquiries in the Early Modern Era Logan J. Connors is Associate Professor of Modern Languages and Literatures at the University of Miami. His next research project investigates connections between theater and the military in France and its colonies from 1680 to 1815

    The "Bad Boys" of Tennis: Shifting gender and social class relations in the era of Nastase, Connors and McEnroe

    No full text
    Tennis from the mid-1970s until the mid-1990s witnessed a global downturn in on-court manners. This was exemplified by players such as Ilie Nastase, Jimmy Connors, and John McEnroe, who built reputations on their “bad-boy” images by exhibiting lower levels of sportsmanship, honesty, courtesy to officials, and behavioral restraint; and concomitant higher levels of ostensible petulance, aggressive posturing, and disrespect toward opponents, umpires, and spectators that had been customary in the past. The aims of this article are to examine the extent that this phenomenon was the result of wider shifts in class and gender relations during this period, alongside the rise of consumerist, neoliberal, free-market philosophies in American and British societies. In short, the overall objective is to offer a partial explanation of this phenomenon by locating it in the broader social context of marked changes in society and tennis more specifically.Peer reviewedneoliberal; free market; etiquette; behavior; commercialismAuthor manuscript.

    Modifications and accommodations Medford Middle School teachers make for students demonstrating behaviors of attention deficit/hyperactivity disorder

    Plan BThis study involves Medford Middle School teachers identifying the modifications and/or accommodations they make for children that demonstrate Attention Deficit / Hyperactivity Disorder (AD/HD) type behaviors in the classroom setting. The teachers surveyed encompass all subjects including the Related Arts classes of band, chorus, physical education, art and family and consumer education. The six behaviors identified in the survey were taken from the DSM IV criteria for diagnosing AD/HD in children. Part one of each question was the identified behavior and how the teacher accommodated it. Part two of the behavioral question was a continuum of the level of tolerance the teacher has for each specific behavior. The continuum range from “Little Tolerance” (1) to “Some Tolerance” (3) to “Much Tolerance” (5). In addition to the six behavioral questions, the teachers were asked to respond as to what their definition of a AD/HD 4 504 Plan is and their willingness to make modifications/accommodations for a student that demonstrates AD/HD like behaviors, but does not have an Individual Education Plan (IEP). The findings of this research describe how Medford Middle School teachers utilize at least six to 20 strategies or accommodations in order to help students succeed in school. Twelve percent of teachers demonstrated knowledge of what a 504 Plan is. The last question surveyed their willingness to make modifications or accommodations without an IEP or 504 Plan directing them. The average responses by grade ranged from 2.6 (slightly less than “somewhat likely” to modify or accommodate) in eighth grade to 3.5 (slightly higher than “somewhat likely” to modify or accommodate) in fifth grade. Sixty-three percent of Medford Middle School teachers modify, accommodate or utilize behavior management strategies for teaching children that demonstrate AD/HD like behaviors

    A jet-dominated model for a broad-band spectral energy distribution of the nearby low-luminosity active galactic nucleus in M94

    We have compiled a new multiwavelength spectral energy distribution (SED) for the closest obscured low-ionization emission-line region active galactic nucleus (AGN), NGC 4736, also known as M94. The SED comprises mainly high-resolution (mostly sub-arcsecond, or, at the distance to M94, ≲23 pc from the nucleus) observations from the literature, archival data, as well as previously unpublished sub-millimetre data from the Plateau de Bure Interferometer (PdBI) and the Combined Array for Research in Millimeter-wave Astronomy, in conjunction with new electronic MultiElement Radio Interferometric Network (e-MERLIN) L-band (1.5 GHz) observations. Thanks to the e-MERLIN resolution and sensitivity, we resolve for the first time a double structure composed of two radio sources separated by ∼1 arcsec, previously observed only at higher frequency. We explore this data set, which further includes non-simultaneous data from the Very Large Array, the Gemini telescope, the Hubble Space Telescope and the Chandra X-ray observatory, in terms of an outflow-dominated model. We compare our results with previous trends found for other AGN using the same model (NGC 4051, M81*, M87 and Sgr A*), as well as hard- and quiescent-state X-ray binaries. We find that the nuclear broad-band spectrum of M94 is consistent with a relativistic outflow of low inclination. The findings in this work add to the growing body of evidence that the physics of weakly accreting black holes scales with mass in a rather straightforward fashion
