Section 1 Introduction

We present quantum Monte Carlo results for the Hubbard model on a ladder using the restructuring method which employ eigenstates of two-site system on a rung to construct a complete set. From technical reasons we concentrate on the case in which the hopping along the leg is much less than the hopping on the rung. We observe the ground state of the half-filled system is made of singlet-like stat...

Replication Section Introduction

The Fama-MacBeth [1] cross-sectional regression technique is a mainstay of empirical finance. Yet researchers and practitioners are forced to reinvent the wheel when implementing this method because the original data and code are not available. Some might think, “Fama and MacBeth’s description of what they did is clear enough and it’s easy to program this method.” Yet, anyone who possesses even...

Introduction to the Special Section

Human Ecology Review, Vol. 16, No. 1, 2009 © Society for Human Ecology The collection of articles for this special section is primarily the result of a symposium organized by Dr. Tom Dietz that took place at the XIV International Conference of the Society for Human Ecology. The symposium as well as this collection of papers represents a unique cross-section of scholars at various stages in thei...

Introduction to the Special Section

ystem identification refers broadly to the problem of developing empirical mathematical models of systems based on excitation and response measurements. Such models are useful for enhancing physical understanding; analyzing system properties; and performing simulation, prediction, filtering, state estimation, monitoring, and fault diagnosis as well as control. Practical interest in system ident...
