Determining the performance of ecosystem services at the city or regional level cannot accurately take into account the fine differences between green or gray structures. The supply of regulating ecosystem services in, for instance, parks can differ as parks vary in their land cover composition. A comprehensive ecosystem service assessment approach also needs to reflect land use to consider the...

Australia’s publicly owned and managed National Parks estate has been largely quarantined from the micro-economic reforms that have been instituted across most other sectors of the economy. The public good, natural monopoly and equity arguments that are used to justify a continued dominance by the public sector in the production and provision of Park benefits are not watertight. Opening up the ...

A wearable 'helmet' version of the S cone isolating technique was constructed to explore vision at equiluminance. For my high school summer science project, I visited parks and streets while wearing the helmet and report that the helmet appears to have captured the main properties described for the large-scale, more cumbersome stage version.

Urban parks are important settings for physical activity, but few natural experiments have investigated the influences of park modifications on activity patterns and visitor profiles.We assessed the impact of implementing a municipal policy on off-leash dogs in city parks in Calgary (Alberta, Canada). Systematic observation undertaken in 2011 and 2012 within four parks captured patterns of use,...

The recent sharp drop in the cost of photovoltaic (PV) electricity generation accompanied by globally rapidly increasing investment in PV plants calls for new planning and management tools for large-scale distributed solar networks. Of major importance are methods to overcome intermittency of solar electricity, i.e., to provide dispatchable electricity at minimal costs. We find that pairs of el...

This paper was written by Jonathan Weiss of the George Washington University Center on Sustainability and Regional Growth* in collaboration with the Funders’ Network for Smart Growth and Livable Communities. It is the fourth in a series of translation papers sponsored by the Funders’ Network to translate the impact of sprawl upon issues of importance to America’s communities and to suggest oppo...

The principal and school leadership team have established and are driving a strong, positive learning culture, grounded in evidence from research and practice. Explicit and clear school-wide expectations have been established with families, teachers, and students. Strong procedures are in place to encourage a school-wide, shared responsibility for student management, and to encourage the develo...

In 1920, Jacques Gréber published what was and still is the largest book on U.S. architecture and urban design ever issued in France. His dual agenda was to stress the impact of Beaux-Arts design methods (presenting his gardens and Philadelphia parkway as highlights of this trend), and to advocate the practical accomplishments of a pragmatic and affluent civilization. Showcasing an "edited" Nor...

Transportation engineers and urban planners often report uncertain estimates as precise numbers, and unwarranted trust in the accuracy of these precise numbers can lead to bad transportation and landuse policies. This paper presents data on parking and trip generation rates to illustrate the misuse of precise numbers to report statistically insignificant estimates. Beyond the problem of statist...
