Jurisdictional Size and Residential Development: Are Large-Scale Local Governments More Receptive to Multifamily Housing?
Urban Affairs Review

Abstract
In the United States, particularly in high-cost urban areas, local resistance to multifamily housing development has been widely noted. In many metropolitan areas, legal authority over land-use regulation is assigned to jurisdictions that often are very small, and some scholars argue that this small-scale local control institutionalizes neighborhood-level opposition to new construction. Using census tracts as units of analysis, we assess the relationship between the population size of the city, county, or township that regulates a tract’s land use and the change in multifamily units between two recent waves of the American Community Survey (2008–2012 and 2014–2018). Results of regression analysis indicate that larger jurisdictional population size is indeed associated with increased multifamily construction. However, the relationship applies only for jurisdictions with populations exceeding 100,000 and decays at jurisdictional populations of more than 1 million. This nonlinearity may reflect quasi-monopolistic land-use control in the largest jurisdictions.

Modeling Non-Ignorable Attrition and Measurement Error in Panel Surveys: An Application to Travel Demand Modeling

Abstract
Modern panel surveys frequently suffer from high and non-ignorable attrition, and transportation surveys suffer from poor travel time estimates. The initial sampling process for most transportation surveys is also non-ignorable since rare travel modes are oversampled (and mode choice is the key dependent variable). This paper examines new multiple imputation methods for adjusting forecasts and model estimates to account for these problems in a new panel survey of 1500 commuters in San Diego, California. These data are collected to evaluate charging solo commuters to use an existing 8-mile underutilized freeway carpool lane. We illustrate the impact of attrition and measurement error on a standard conditional logit model of commuters’ mode choice (solo drive in free lanes, pay to solo drive in the carpool lanes, or carpool for free in carpool lanes). Although the attrition rate between waves is 40% and non-ignorable, the quantitative impact on the results is negligible. However, measurement error in travel time does have an important impact on the key results from our model. Finally, failure to account for the measurement error process using multiple imputations yields a downward bias of at least 50% in the standard errors of the logit coefficient estimates.

The trip chaining activity of Sydney residents: A cross-section assessment by age group with a focus on seniors

Abstract
In this paper, we use a pooled (2002-2004) cross-section of the Sydney travel survey, an annual continuous survey since 1997, to investigate the current profile of trip chaining travel activity of individuals in five-year groups, with a particular focus on those over 64 years old (i.e., seniors), given the aging of the population. Multiple correspondence analysis is used to establish causality of nonlinear and non-monotonic relationships between socioeconomic descriptors and measures of travel behavior (assessed as trip chains). A benchmark setting for today not only establishes the way in which the elderly currently `cope’ with the existing supply network and the available modal alternatives, given their needs, but also is useful in providing hints as to what might be the key emerging transport policy and planning challenges in the future to serve this growing and increasingly influential population sub-strata. The main policy finding is that after age 64, travel demand shifts from car driving (partly linked to loss of driving license, but partly through choice), to car passenger and then to public transport in complex trip chains, especially for singles and for all women.

Abstract
The focus of this paper is on the demonstration that some rather well-known network based formulations in operations research, that have heretofore largely gone unnoticed in activity-based travel research, offer a potentially powerful technique for advancing the general development of the activity-based modeling approach. These formulations can provide an analytical framework that unifies the complex interactions among the resource allocation decisions made by households in conducting their daily affairs outside the home, while preserving the utility-maximizing principles presumed to guide such decisions. A mathematical programming formulation is developed and used to identify the similarities and differences between traditional trip-based modeling methodologies and those pertaining to an activity-based approach. It is demonstrated that the two approaches are directly related.

A Difference Method for Plane Problems in Magnetoelastodynamics
Journal of Applied Mechanics
Publication Date
September 1, 1972
Author(s)
Abstract
The two-dimensional equations of magnetoelastodynamics are considered as a symmetric hyperbolic system of linear first-order partial-differential equations in three independent variables. The characteristic properties of the system are determined and a numerical method for obtaining the solution to mixed initial and boundary-value problems in plane magnetoelastodynamics is presented. Results on the von Neumann necessary condition are presented. Application of the method to a problem which has a known solution provides further numerical evidence of the convergence and stability of the method.
