    THOSE BORING, ARCANE PART-WRITING EXERCISES

    Get PDF
    Music theory students and teachers alike have long complained about the sterile part-writing exercises that are a staple of music theory classes. With glee people love to point out how works from the repertoire frequently feature elements that are forbidden in exercises, thereby seeming to prove the ineptitude of the arcane rules forced upon generations of students. Considering the glaring divide between compositional practice and the guidelines for these exercises, are there truly any benefits for continuing to teach in this old-fashioned manner? If their purpose is to mimic a specific artistic style, such as witnessed in the chorales of J. S. Bach, then the utility of part-writing exercises would indeed be extremely questionable. But if their goals are more properly understood as a means of enhancing sensitivity to certain basic procedures of tonal music, then part-writing exercises could rightly be valued as important pedagogical tools for developing vital skills that in turn can inform the performance, hearing, analysis, and composition of tonal music

    The mid-UV population of the nucleus and the bulk of the post-merger NGC 3610

    Full text link
    The very center of NGC~3610, a clearly disturbed giant elliptical generally assumed to be a post-merger remnant, appears dominated in the mid-UV (2500-3200 A spectral region) by a stellar population markedly different from that dominating the bulk of its stellar body. I want here to make use of the mid-UV spectra of NGC~3610 as seen through tiny (∌\sim1") and large (10"×\times20") apertures as a diagnostic population tool. I compare archive IUE/LWP large aperture and HST/FOS UV data of NGC 3610. The strength of mid-UV triplet (dominated by the turnoff population) shows a remarkable drop when switching from the galaxy central arcsec (FOS aperture) to an aperture size comparable to ∌\sim0.5 re_e (IUE). The sub-arsec (mid)-UV properties of this galaxy involved in a past merger reveal a central metal enrichment which left intact the bulk of its pre-existing population.Comment: 6 pages, 2 figures, accepted for publication in astronomy and Astrophysic

    Temperature sensitivity of the pyloric neuromuscular system and its modulation by dopamine

    Get PDF
    We report here the effects of temperature on the p1 neuromuscular system of the stomatogastric system of the lobster (Panulirus interruptus). Muscle force generation, in response to both the spontaneously rhythmic in vitro pyloric network neural activity and direct, controlled motor nerve stimulation, dramatically decreased as temperature increased, sufficiently that stomach movements would very unlikely be maintained at warm temperatures. However, animals fed in warm tanks showed statistically identical food digestion to those in cold tanks. Applying dopamine, a circulating hormone in crustacea, increased muscle force production at all temperatures and abolished neuromuscular system temperature dependence. Modulation may thus exist not only to increase the diversity of produced behaviors, but also to maintain individual behaviors when environmental conditions (such as temperature) vary

    A Statistical Treatment of the Gamma-Ray Burst "No Host Galaxy" Problem: II. Energies of Standard Candle Bursts

    Full text link
    With the discovery that the afterglows after some bursts are coincident with faint galaxies, the search for host galaxies is no longer a test of whether bursts are cosmological, but rather a test of particular cosmological models. The methodology we developed to investigate the original "no host galaxy" problem is equally valid for testing different cosmological models, and is applicable to the galaxies coincident with optical transients. We apply this methodology to a family of models where we vary the total energy of standard candle bursts. We find that total isotropic energies of E<2e52~erg are ruled out while log(E)~53 erg is favored.Comment: To appear in Ap.J., 514, 15 pages + 7 figures, AASTeX 4.0.

    The Multiphase Intracluster Medium in Galaxy Groups Probed by the Lyman Alpha Forest

    Full text link
    The case is made that the intracluster medium (ICM) in spiral-rich galaxy groups today probably has undergone much slower evolution than that in elliptical-rich groups and clusters. The environments of proto-clusters and proto-groups at z > 2 are likely similar to spiral-rich group environments at lower redshift. Therefore, like the ICM in spiral-rich groups today, the ICM in proto-groups and proto-clusters at z > 2 is predicted to be significantly multiphased. The QSO Lyman alpha forest in the vicinity of galaxies is an effective probe of the ICM at a wide range of redshift. Two recent observations of Lyman alpha absorption around galaxies by Adelberger et al. and by Pascarelle et al are reconciled, and it is shown that observations support the multiphase ICM scenario. Galaxy redshifts must be very accurate for such studies to succeed. This scenario can also explain the lower metallicity and lower hot gas fraction in groups.Comment: 4 pages, 1 figure, replaced with the version after proo

    Cooperation, Proximity, and Social Innovation: Three Ingredients for Industrial Medium-Sized Towns’ Renewal?

    Get PDF
    Over several decades, medium-sized industrial towns have suffered from a combination of economic and political processes: Deindustrialization, metropolization, and withdrawal of public services. After two decades in which they have been somewhat neglected (in favor of metropolises), there have recently been State and European public policies aimed at them. Medium-sized cities are not homogeneous and present several trajectories. Based on quantitative approach in France, we highlight the very diverse socio-economic dynamics of French medium-sized industrial towns. Thus, far from widespread decline or shrinking dynamics, some of these cities are experiencing an economic rebound. This is the case of Romans-sur-Isùre, a medium-sized town located in the south-east of France. Focusing our qualitative analyze on this city, we try to understand this type of process. In this medium-sized town, former capital of the shoe industry, local stakeholders, private, and public try to support a productive renewal. The results of our case study highlight the role that cooperation, spatial and organizational proximity, and social innovation could play in the renewal of productive economy in medium-sized industrial towns. Even if the economic situation remains difficult for many medium-sized cities in France as in Europe, we argue that they could have a productive future making and ultimately take advantages of their “medium-sized” attributes.

    Clinical trial update: implications and management of residual disease after neoadjuvant therapy for breast cancer

    Get PDF
    Neoadjuvant chemotherapy for breast cancer has a well-established role in the management of patients with locally advanced or early stage disease. Multiple trials have demonstrated superior survival outcomes in individuals achieving a pathologic complete response at the time of definitive surgery, and sophisticated genetic methods may predict which patients will be in this category. Those with less than a pathologic complete response remain at significant risk of recurrent disease, and currently no further standard therapy exists. Ongoing studies of novel agents may lead to improved therapeutic outcomes for this high-risk population

    Dynamics of Bulk vs. Nanoscale WS_2: Local Strain and Charging Effects

    Full text link
    We measured the infrared vibrational properties of bulk and nanoparticle WS2_2 in order to investigate the structure-property relations in these novel materials. In addition to the symmetry-breaking effects of local strain, nanoparticle curvature modifies the local charging environment of the bulk material. Performing a charge analysis on the \emph{xy}-polarized E1u_{1u} vibrational mode, we find an approximate 1.5:1 intralayer charge difference between the layered 2H material and inorganic fullerene-like (IF) nanoparticles. This effective charge difference may impact the solid-state lubrication properties of nanoscale metal dichalcogenides.Comment: 6 pages, 5 figure

    Thirty Years On: Reflections on Haydn’s “Farewell” Symphony by James Webster

    Get PDF
    It has been just over thirty years since James Webster published his influential monograph Haydn’s “Farewell” Symphony and the Idea of Classical Style: Through-Composition and Cyclic Integration in His Instrumental Music (Cambridge University Press, 1991). To honor the anniversary of Webster’s groundbreaking book, the Encounters with Eighteenth-Century Music: A Virtual Forum steering committee asked L. Poundie Burstein, Elaine Sisman, and W. Dean Sutcliffe to offer perspectives on the book, and James Webster to respond to their perspectives. The interesting online session occurred on Tuesday, October 18, 2022, and included a lively open discussion following the presentations and Webster’s response. The three presenters and Webster graciously consented to publish their perspectives and response in this article to inaugurate the 2023 “Farewell” volume of HAYDN: Online Journal of the Haydn Society of North America
