Nationbuilding 101: Property, Liberty, and Corporate Governance
Nationbuilders in less developed countries need to understand how Western legal systems with "property" at their center have materially accounted for Western prosperity and liberty, but legal definitions of property are so abstruse that explication of this vital concept is made difficult. This paper finds an historical definitional essence to property in the right to exclude and maintains that liberty and property both share this essential meaning. The problems of corporate governance are then placed in the context of the exclusionary concept of property/liberty.http://deepblue.lib.umich.edu/bitstream/2027.42/39913/3/wp528.pd

Changing times for animal damage control
At present, the USDA’s Animal and Plant Health Inspection Service (APHIS) is in the process of taking over the national animal damage control program from the U.S. Fish & Wildlife Service. I discuss the history of the federal animal damage control program with the U.S. Department of Agriculture beginning in the late 1800s. Once USDA assumes full control of the present program, the areas of emphasis will be cooperative operational control, research, and informational and educational efforts. For the first time, the program will have a Secretary’s advisory committee on ADC. An interdepartmental policy committee chaired by APHIS will involve other USDA agencies: Forest Service, Extension Service, Economic Research Service, Agricultural Research Service, and Cooperative State Research Service. Details of future efforts in research, and in information and education, are discussed

Late Time Behaviors of an Inhomogeneous Rolling Tachyon
We study an inhomogeneous decay of an unstable D-brane in the context of
Dirac-Born-Infeld~(DBI)-type effective action. We consider tachyon and
electromagnetic fields with dependence of time and one spatial coordinate, and
an exact solution is found under an exponentially decreasing tachyon potential,
, which is valid for the description of the late time
behavior of an unstable D-brane. Though the obtained solution contains both
time and spatial dependence, the corresponding momentum density vanishes over
the entire spacetime region. The solution is governed by two parameters. One
adjusts the distribution of energy density in the inhomogeneous direction, and
the other interpolates between the homogeneous rolling tachyon and static
configuration. As time evolves, the energy of the unstable D-brane is converted
into the electric flux and tachyon matter.Comment: 17 pages, 1 figure, version to appear in PR
Soliton Resonances for MKP-II
Using the second flow - the Derivative Reaction-Diffusion system, and the
third one of the dissipative SL(2,R) Kaup-Newell hierarchy, we show that the
product of two functions, satisfying those systems is a solution of the
modified Kadomtsev-Petviashvili equation in 2+1 dimension with negative
dispersion (MKP-II). We construct Hirota's bilinear representation for both
flows and combine them together as the bilinear system for MKP-II. Using this
bilinear form we find one and two soliton solutions for the MKP-II. For special
values of parameters our solution shows resonance behaviour with creation of
four virtual solitons. Our approach allows one to interpret the resonance
soliton as a composite object of two dissipative solitons in 1+1 dimensions.Comment: 11 pages, 2 figures, Talk on International Conference "Nonlinear

Quantum phases of a Feshbach-resonant atomic Bose gas in one dimension
We study an atomic Bose gas with an s-wave Feshbach resonance in a
one-dimensional optical lattice, with the densities of atoms and molecules
incommensurate with the lattice. At zero temperature, most of the parameter
region is occupied by a phase in which the superfluid fluctuations of atoms and
molecules are the predominant ones, due to the phase fluctuations of atoms and
molecules being locked by a Josephson coupling between them. When the density
difference between atoms and molecules is commensurate with the lattice, two
additional phases may exist: the two component Luttinger liquid where both the
atomic and molecular sectors are gapless, and the inter-channel charge density
wave where the relative density fluctuations between atoms and molecules are
frozen at low energy.Comment: 4+epsilon pages, 3 figures; references adde
