Human-controlled survival of nonhumans

Treves et al. are right about the need for morally just preservation of nonhumans. Their suggestions can move us in that direction. But isn’t what only humans are capable of doing in analyzing and solving these problems, in its broadest sense, “anthropocentrism”

The contribution of a psychiatric clinic to the solution of behavior and personality problems of one hundred children

Thesis (M.A.)--Boston University This item was digitized by the Internet Archive.This follow-up study was based on cases of one hundred children, manifesting behavior and personality problems, who had been referred to the Out-Patient Department of the Boston Psychopathic Hospital. The object of the study was to discover what had happened to these children in terms of the modification of their behavior during a five year period since their initial visit to the clinic. The study was also concerned with the use which referring agencies and individuals had made of clinic recommendations. Consecutive cases of children, sixteen years of age and under, were used. All had been seen by one psychiatrist five years earlier and all had exhibited behavior and personality problems

Base Change for the Iwahori-Hecke Algebra of GL2GL_2

Let F be a local non-Archimedean field of characteristic not equal to 2, let E/F be a finite unramified extension field, and let σ be a generator of Gal(E, F). Let f be an element of Z(H_{I_E}), the center of the Iwahori-Hecke algebra for GL2(E), and let b be the Iwahoric base change homomorphism from Z(H_{I_E}) to Z(H_{I_F} ), the center of the Iwahori-Hecke algebra for GL2(F) [8]. This paper proves the matching of the σ-twisted orbital integral over GL2(E) of f with the orbital integral over GL2(F) of bf. To do so, we compute the orbital and σ-twisted orbital integrals of the Bernstein functions z_μ. These integrals are computed by relating them to counting problems on the set of edges in the building for SL2. Surprisingly, the integrals are found to be somewhat independent of the conjugacy class over which one is integrating. The matching of the integrals follows from direct comparison of the results of these computations. The fundamental lemma proved here is an important ingredient in study of Shimura varieties with Iwahori level structure at a prime p [7]

The impact of climate change on ski resort operations and development : opportunities and threats

Thesis (S.M. in Real Estate Development)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections."September 2007."Includes bibliographical references (leaves 54-58).This thesis serves as a pedagogical guide to the ski resort industry, and presents a broad overview of the unique issues that accompany climate change. The paper also provides recommendations to resort developers as to which regions of North America will likely become desirable destination for skiers in light of such changes. The ski resort industry is on the cutting edge with respect to sustainable building techniques and adoption of innovative "green" principles in day-to-day operations. But while these efforts are admirable and set an important precedent, in the global context they do little to stem the tide of global warming which penalizes indiscriminately. It is therefore necessary for stakeholders within the ski industry to not only embrace adoption strategies, but also to consider what preemptive actions can be taken to capitalize on global warming. Using historical annual total snowfall records and "skier visit" data, this study intends to quantify the extent to which climate change has impacted resort operations in different regions of the United States over the last several decades. In addition, the paper provides an overview of current and future effects of climate change on North America's ski resort industry and provides recommendations as to how these operators can adapt to ever changing conditions over the next 30 - 50 years. This is followed by a review of climate adaptation practices currently employed by resort operators and stakeholders. With few exceptions, existing literature on this topic has neglected to consider what opportunities might emerge as a result of climate change. While the field of climatology is an ever evolving science, the ski industry would be wise to take note as global warming is likely to prove one of those tectonic forces that gradually - but powerfully - changes the economic landscape in which they operate.by Daniel D.D.

3D reduction of the N-body Bethe-Salpeter equation

We perform a 3D reduction of the two-fermion Bethe-Salpeter equation, by series expansion around a positive-energy instantaneous approximation of the Bethe-Salpeter kernel, followed by another series expansion at the 3D level in order to get a manifestly hermitian 3D potential. It turns out that this potential does not depend on the choice of the starting approximation of the kernel anymore, and can be written in a very compact form. This result can also be obtained directly by starting with an approximation of the free propagator, based on integrals in the relative energies instead of the more usual delta-constraint. Furthermore, the method can be generalized to a system of N particles, consisting in any combination of bosons and fermions. As an example, we write the 3D equation for systems of two or three fermions exchanging photons, in Feynman or Coulomb's gauge.Comment: 22 pages, 3 figures in one single ps file. In the first revision, the self-energy corrections to the propagator have been taken into account. The three figures were gathered in a single ps file instead of three eps. In this second revision (after submission to Nuclear Physics A and refereeing) some explanations have been added, plus a new subsection about the scattering of a particle by a bound stat

Relativistic three-body bound states and the reduction from four to three dimensions

Beginning with an effective field theory based upon meson exchange, the Bethe-Salpeter equation for the three-particle propagator (six-point function) is obtained. Using the one-boson-exchange form of the kernel, this equation is then analyzed using time-ordered perturbation theory, and a three-dimensional equation for the propagator is developed. The propagator consists of a pre-factor in which the relative energies are fixed by the initial state of the particles, an intermediate part in which only global propagation of the particles occurs, and a post-factor in which relative energies are fixed by the final state of the particles. The pre- and post-factors are necessary in order to account for the transition from states where particles are off their mass shell to states described by the global propagator with all of the particle energies on shell. The pole structure of the intermediate part of the propagator is used to determine the equation for the three-body bound state: a Schr{\"o}dinger-like relativistic equation with a single, global Green's function. The role of the pre- and post-factors in the relativistic dynamics is to incorporate the poles of the breakup channels in the initial and final states. The derivation of this equation by integrating over the relative times rather than via a constraint on relative momenta allows the inclusion of retardation and dynamical boost corrections without introducing unphysical singularities.Comment: REVTeX, 21 pages, 4 figures, epsf.st
