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.

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...

Japan, as one of the most developed country in logistics field in the world, has developed its logistics parks earlier. This paper takes Japan’s logistics park as the subject in research. By analyzing Japan’s experiences of developing logistics parks, this paper tempts to find out problems in China’s logistics parks and put forward suggestions for further development and construction.

We compile over 270 wildlife counts of Kenya's wildlife populations conducted over the last 30 years to compare trends in national parks and reserves with adjacent ecosystems and country-wide trends. The study shows the importance of discriminating human-induced changes from natural population oscillations related to rainfall and ecological factors. National park and reserve populations have de...

INTRODUCTION Mounting evidence documents the importance of urban form for active travel, but international studies could strengthen the evidence. The aim of the study was to document the strength, shape, and generalizability of relations of objectively measured built environment variables with transport-related walking and cycling. METHODS This cross-sectional study maximized variation of env...
