The New York City Housing Receivership and Community Management Programs
Each year New York City landlords abandon buildings containing an estimated 10,000 apartments, forcing tenants to leave as the ownerless buildings plunge into decay. At least half of these buildings are structurally solid and might last several more decades if not abandoned. Most are found in areas where problem buildings- buildings which have a potential for abandonment- will most likely be found. New York City has instituted a number of programs for dealing with buildings which are headed toward abandonment. They include code-enforcement, emergency repair and receivership programs, foreclosure for nonpayment of property taxes, and rehabilitation programs involving municipal loans, housing-repair contracts, and the conversion of buildings to tenant-owned cooperatives. This Note will trace the history, development, and operation of the New York City Housing Receivership Program, placing special emphasis on recent developments and innovations in the area of community group involvement
Dynamics of Black Hole Pairs I: Periodic Tables
Although the orbits of comparable mass, spinning black holes seem to defy
simple decoding, we find a means to decipher all such orbits. The dynamics is
complicated by extreme perihelion precession compounded by spin-induced
precession. We are able to quantitatively define and describe the fully three
dimensional motion of comparable mass binaries with one black hole spinning and
expose an underlying simplicity. To do so, we untangle the dynamics by
capturing the motion in the orbital plane. Our results are twofold: (1) We
derive highly simplified equations of motion in a non-orthogonal orbital basis,
and (2) we define a complete taxonomy for fully three-dimensional orbits. More
than just a naming system, the taxonomy provides unambiguous and quantitative
descriptions of the orbits, including a determination of the zoom-whirliness of
any given orbit. Through a correspondence with the rationals, we are able to
show that zoom-whirl behavior is prevalent in comparable mass binaries in the
strong-field regime. A first significant conclusion that can be drawn from this
analysis is that all generic orbits in the final stages of inspiral under
gravitational radiation losses are characterized by precessing clovers with few
leaves and that no orbit will behave like the tightly precessing ellipse of
Mercury. The gravitational waveform produced by these low-leaf clovers will
reflect the natural harmonics of the orbital basis -- harmonics that,
importantly, depend only on radius. The significance for gravitational wave
astronomy will depend on the number of windings the pair executes in the
strong-field regime and could be more conspicuous for intermediate mass pairs
than for stellar mass pairs.Comment: 19 pages, lots of figure
Activating Latino Millennial Civic Power: A Report of the Aspen Institute Latinos and Society Convening - Unlocking Latino Millennial Civic Potential

Beyond the standard model with B and K physics
In the first part of the talk the flavor physics input to models beyond the
Standard Model is described. One specific example of such a new physics model
is given: a model with bulk fermions in one non-factorizable extra dimension.
In the second part of the talk we discuss several observables that are
sensitive to new physics. We explain what type of new physics can produce
deviations from the Standard Model predictions in each of these observables.Comment: 10 pages, 5 figures, Invited talk presented at the 21st International

Forked Temperley-Lieb Algebras and Intermediate Subfactors
We consider noncommuting pairs P,Q of intermediate subfactors of an
irreducible, finite-index inclusion N in M of II_1 factors such that P and Q
are supertransitive with Jones index less than 4 over N. We show that up to
isomorphism of the standard invariant, there is a unique such pair
corresponding to each even value [P:N]=4cos^2(pi/2n) but none for the odd
values [P:N]=4cos^2 (pi/(2n+1)).
We also classify the angle values which occur between pairs of intermediate
subfactors with small index over their intersection: if [P:N] < 4, then the
unique nontrivial angle value is always cos^-1 (1/([P:N]-1)).Comment: 19 pages. Stylistic revisions and reference added to Evans-Gould 1994

Gender dynamics in Polish drama after 2000
When discussing Polish theatre scene, critics and scholars often lament the decline of âhigh artâ and the disappearance of ambitious Romantic repertoire from Polish theatres after 1989. Yet, strangely enough none of these ongoing debates identifies such problems as lack of gender equality; devastating effects of anti-abortion law; insufficient network of support for victimised and unemployed women; exceptionally high tolerance for sexist, homophobic and misogynist attitudes in both public and private spheres of activities; as well as the general dominant patriarchal structure of power. This is even more surprising when one reads plays written by female and male writers published (and/or performed) after 2000 as their dramatic worlds address many feminist and gender-related concerns. This study (focusing on gender dynamics) reveals that the gap between the voice of critical and scholarly inquiry and the âvoiceâ of the plays themselves has been widening rather than narrowing. The article addresses this concern with reference to selected plays by Krystyna Kofta, Monika Powalisz, Magdalena Fertacz, Dana ĆukasiĆska as well as Marek Pruchniewski, Krzysztof Bizio, PrzemysĆaw Wojcieszek and Robert Bolesto
Introduction to flavor physics
This set of lectures covers the very basics of flavor physics and are aimed
to be an entry point to the subject. A lot of problems are provided in the hope
of making the manuscript a self study guide.Comment: 45 pages. Lectures given at the "2009 European School of High-Energy
Physics," Bautzen, Germany, June 14-27, 2009, and at the "Flavianet School on
