Dropping Out Of High School: An Inside Look, Michelle Fine

Publications and Research

In September, 1984, I began an ethnography of student life in and out of a New York City public high school to figure out why urban students drop out of high school at such extraordinary rates. By December, why urban students stay in high school through graduation struck me as an equally compelling question.

A Sentence Test Of Speech Perception: Reliability, Set Equivalence, And Short Term Learning, Arthur Boothroyd, Laurie Hanin, Theresa Hnath

Publications and Research

The general goal of this project is to study the processes and outcomes of speech perception training in postlingually deafened adults fitted with cochlear implants. As part of this work we need to measure speech perception performance, using materials that place different relative emphases on the several components of the speech perception process. One of the materials that we have developed consists of 48 sets of topic-related sentences (see report #RCIl). These sets have been videorecorded by one female talker. One of the audio tracks contains the full acoustical signal. The other contains the output from an electroglottograph and consists …

Qcd Vacuum As A Chromomagnetic Superconductor: Microscopic Physics, V. Parameswaran Nair, C. Rosenzweig

Publications and Research

The compactness of the QCD gauge group leads to the existence of chromomagnetic monopole configurations. The interactions of these monopoles are studied using electric-magnetic duality as a guide. It is shown that the gluon-monopole interaction acquires an extra minus sign which tends to destabilize the monopole configurations. A model is presented which exploits this observation. We present a scenario where the monopoles condense, giving chromomagnetic superconductivity, via a first-order phase transition at a scale where the electric and magnetic charges are equal, i.e., α = 1/2 . In this vacuum medium gluons propagate like 1/k⁴ which is now seen …

A Methodology For The Study Of Children's Environmental Knowledge In Other Cultures, Cindi Katz

Publications and Research

This paper presents a methodology which I used to study the content and acquisition of children's environmental knowledge as central to the social reproduction of a rural agricultural economy in the Sudan. My approach was forged drawing on methods of geography, linguistics and anthropology to provide information on (1) how children learn to interact productively with their environment, (2) the nature of their interactions and (3) their knowledge of environmental processes and resources. In this paper I will describe first the methodology adopted including participant observation, ethnosemantic interviews, child-led walks, environmental modeling and "geo-dramas". I will then discuss its use …

(Super)Conformal Symmetry Breaking, Andrew Strominger, V. Parameswaran Nair

Publications and Research

We argue that the only consistent way to break conformal invariance in a quantum theory of gravity is spontaneously in a finite locally conformal supersymmetric theory. This generically occurs whenever scalar fields are present. Covariant surface-integral expressions for the super-charge and four-momentum in terms of asymptotically constant spinor fields are derived. These are used to discuss stability and other aspects of the theory.

Bags Vs. Strings: Hadrons In Type I And Type Ii Superconducting Vacua, V. Parameswaran Nair, C. Rosenzweig

Publications and Research

Two popular models for hadronic structure are bags and strings. Both involve analogies with superconductivity. We claim that the most appropriate analogies are type I superconductors for bags and type II superconductors for strings. The structures of hadrons is somewhat different for the two situations. In principle, and in practice in the real world, it is the similarities which are most important. These include linear confining potentials, linearly rising Regge trajectories and short distance Coulomb potentials. These are all generic properties of bound states in a superconductor and the main distinctions between bags and strings is under what circumstances these …

Mixing Angles, B-Meson Life-Time In The Six-Quark Model Based On So(10) X U(1)Pq, V. Parameswaran Nair, Louis Michel, Kameshwar C. Wali

Publications and Research

We show that a recently proposed multigenerational, grand unified model with three parameters (top-quark mass and two phases of Higgs vacuum expectation values) yields results in good agreement with the most recent phenomenological limits placed on the weak mixing angles of the quarks. These limits take into account the experimental value for B-meson life-time.

Peccei-Quinn Symmetry As Flavor Symmetry And Grand Unification, Aharon Davidson, V. Parameswaran Nair, Kameshwar C. Wali

Publications and Research

We consider the possibility of identifying the Peccei-Quinn (PQ) symmetry as also the flavor symmetry in multigenerational grand unification schemes. The essential ingredient, a global, axial U(1) symmetry in the PQ mechanism to avoid the strong CP-violation problem provides useful constraints on the fermion —Higgs-boson couplings in the theory, thereby leading to identical "canonical" forms for fermion mass matrices in both the charged sectors. These forms are the conjectured Fritzsch-type matrices exhibiting the "nearest-neighbor" interactions in generation space. From among the popular schemes for grand unification, SO(10) emerges as one which has several advantages over the others for constructing multigenerational …

The Impact Of Language On Musical Composition In Ghana: An Introduction To The Musical Style Of Ephraim Amu, V. Kofi Agawu

Publications and Research

In most cultures of the world, the creative act of composition may be defined simply as the transformation of pre-existing material into new, individualized structures. The precompositional resource may be a system such as the hierarchical arrangement of triads that forms the basis of Western tonality, a set of formulas that generates such genres as Gregorian chant and West African storytelling, or even a rigidly defined set of relationships such as those inherent in a twelve-tone row. In each case, the precompositional elements provide a framework for the analysis and interpretation of the composition.

Critical Note On The Usefulness Of Attention Deficit As A Clinical Syndrome, David Shaffer, Irvin Sam Schonfeld

Publications and Research

Parental ratings of overactivity are unrelated to teachers' ratings of overactivity or to laboratory measures of inattention. Teachers' ratings of overactivity correlate strongly with teachers' ratings of inattention as well as to laboratory measures of inattention. Teachers' ratings of inattention, however, are unrelated to laboratory measures of inattention when IQ is controlled. There are considerable definitional problems relating to the symptoms of hyperactivity and inattention, making it difficult create a behavioral definition of the psychiatric syndrome of attention deficit disorder.

Heinrich Schenker As An Interpreter Of Beethoven's Piano Sonatas, William Rothstein

Publications and Research

There was a time when it seemed necessary for admirers of the work of Heinrich Schenker to remind the musical community periodically that it had grown out of a lifetime of practical musical experience—that is, that Der freie Satz did not represent a self-contained system of theoretical speculation. Schenker himself tried repeatedly throughout his career to impress this point upon his readers. In recent years, fortunately, this reminder—which had threatened to become merely ritualistic—has become somewhat less necessary. The change in Schenker's reputation may, it seems, be dated precisely to 1975, when Dover Publications issued an inexpensive reprint of his …

Low-Mass Solitons From Fractional Charges In Quantum Chromodynamics, A. P. Balachandran, V. Parameswaran Nair, N. Panchapakesan, S. G. Rajeev

Publications and Research

Slansky, Goldman, and Shaw have proposed a model to account for the observation of fractionally charged states. We show that in this model, there are expected to be several low-mass solitons (four being in the mass range ∼20-60 MeV) associated with the third homotopy group π₃(SU(3)/SO(3))=Z₄, besides a low-mass (∼30 MeV) Z₂ monopole. Confirmation of these levels and hence of the model has important implications for Cabrera's results on the magnetic monopole. An efficient algorithm for the calculation of π3(G/H) for a general Lie group G and a subgroup H is developed. It is pointed …

The Concept Of Tala In Semi-Classical Music, Peter L. Manuel

Publications and Research

This article explores certain rhythmic features distinctive of the concept of tal in North Indian light-classical music, especially thumri. Particularly salient is the way that ambiguity of beat counts in tals called dipchandi, addha, and jat reflect how these tals are traditionally conceived in terms of drum strokes (dha dhin dha dha dhin etc.) instead of beat counts, which are in fact variable. Published in: National Centre for the Performing Arts: Quarterly Journal (Bombay) 12(4), December 1983. pp. 7-14.

Breakdown Of Flavor Conservation In A Monopole Background, V. Parameswaran Nair

Publications and Research

We give a simple derivation of the catalysis of baryon decay and other flavor-changing processes by monopoles. The role of the axial anomaly is clarified. A general current-algebraic argument which clarifies the nature of flavor violation is also given.

Levels Of Development In The Language Of Deaf Children: Asl Grammatical Processes, Signed English Structures, Semantic Features, Sue Livingston

Publications and Research

This study describes the spontaneous sign language of six deaf children (6 to 16 years old) of hearing parents, who were exposed to Signed English when after the age of six they first attended a school for the deaf. Samples of their language taken at three times over a 15-month period were searched for processes and structures representative or not representative of Signed English. The nature of their developing semantics was described as the systematic acquisition of features of meaning in signs from selected lexical categories (kinship terms, negation, time expression, wh-questions, descriptive terms, and prepositions/conjunctions).

Processes not representative of …
