We show that the full version of the so-called ‘rural hospital theorem’ generalizes to many-to-many matching problems where agents on both sides of the problem have substitutable and weakly separable preferences. We also show that when agents’ preferences satisfy substitutability, the domain of weakly separable pref-

In this note, I extend the work of Echenique (forthcoming) to show that a model of many-to-many matching with contracts may be embedded into a model of many-tomany matching with wage bargaining whenever (1) all agents’ preferences are substitutable and (2) the matching with contracts model is unitary, in the sense that every contractual relationship between a given firm–worker pair is specified...

We present an algorithm for automatically constructing a decompositional shape model from examples. Unlike current approaches to structural model acquisition, in which one-to-one correspondences among appearance-based features are used to construct an exemplar-based model, we search for many-tomany correspondences among qualitative shape features (multi-scale ridges and blobs) to construct a ge...

Theories of interorganizational coordination propose that that the fit between information processing capabilities (structure, process and technology) and information processing needs (environmental, partnership and task uncertainty) is a strong determinant of IOS performance. Recently, electronic marketplaces have replaced many traditional interorganizational systems (IOS). While traditional I...

A new solvable many-body problem is identified. It is characterized by nonlinear Newtonian equations of motion (“acceleration equal force”) featuring one-body and twobody velocity-dependent forces “of goldfish type” which determine the motion of an arbitrary number N of unit-mass point-particles in a plane. The N (generally complex ) values zn(t) at time t of the N coordinates of these moving p...

A new, parametrized many-body tight-binding model is proposed for calculating the potential energy surface for aluminum nanoparticles. The parameters have been fitted to reproduce the energies for a variety of aluminum clusters sAl2, Al3, Al4, Al7, Al13d calculated recently by the PBE0/MG3 method as well as the experimental face-centered-cubic cohesive energy, lattice constant, and a small set ...
