Asphalt concrete pavements are inherently graded viscoelastic structures. Oxidative aging of asphalt binder and temperature cycling due to climatic conditions being the major cause of non-homogeneity. Current pavement analysis and simulation procedures dwell on the use of layered approach to account for these non-homogeneities. The conventional…

Nebraskans of the early twenty-first century have had few encounters with railroads. Passenger trains are nearly extinct, and freights run over only a few main lines. But without the railroads that began to crisscross Nebraska in the 1860s, it may have taken years for significant settlement to reach throughout the territory that became a state in…

Taking public transit can make anyone nervous, especially in a large or medium-sized city where there are many different bus lines going many different places. The author's daughter, Anna, has multiple learning disabilities and may never learn to drive, but she wants to be as independent as possible so the author taught her to ride the bus. This…

The Irvine Minnesota Inventory (IMI) was designed to measure environmental features that may be associated with physical activity and particularly walking. This study assesses how well the IMI predicts physical activity and walking behavior and develops shortened, validated audit tools. A version of the IMI was used in the Twin Cities Walking…

Objective: To investigate the value of additional days of active commuting for meeting a criterion of 300+ minutes of moderate-to-vigorous physical activity (MVPA; 60+ mins/day x 5) during the school week. Methods: Based on seven-day diaries supported by teachers, binary logistic regression analyses were used to predict achievement of MVPA…

Older adults prefer to age in place (AIP), and there are psychological, physiological, and economic benefits in doing so. However, it is especially challenging to AIP in rural communities. AIP models have been tested in urban settings and age-segregated communities, but they are not appropriate for rural communities. This paper presents rural AIP…

Approximately 70% of aviation accidents are attributable to human error. The greatest opportunity for further improving aviation safety is found in reducing human errors in the cockpit. The purpose of this quasi-experimental, mixed-method research was to evaluate whether there was a difference in pilot attitudes toward reducing human error in the…

Climate change planning is fast becoming an important element in university policy and governance. As the causes and impacts of global climate change become more apparent, many universities are embracing climate planning roles as community leaders, educators and researchers, and operators of major activity centers. For example, 685 university…

The new objects of public and open prejudice are Hispanics, primarily Mexicans due to their large population and their proximity to the United States. Because the Iraq War is such a disaster on all fronts, conservatives and reactionaries have shifted their patriotic fervour from invading foreign countries to inveighing against brown-skinned…

Context: Urban-rural disparity is an important issue for injury control in China. Details of the urban-rural disparities in fatal injuries have not been analyzed. Purpose: To target key injury causes that most contribute to the urban-rural disparity, we decomposed total urban-rural differences in 2006 injury mortality by gender, age, and cause.…

Multitasking performance is relevant in everyday life and job analyses highlight the influence of multitasking over several diverse occupations. Intelligence is the best single predictor of overall job performance and it is also related to individual differences in multitasking. However, it has been shown that working memory capacity (WMC) is…

Theories and methods from the prospective memory literature were used to anticipate how individuals would maintain and retrieve intentions in a continuous monitoring dynamic display task. Participants accepted aircraft into sectors and detected aircraft conflicts during an air traffic control simulation. They were sometimes required to substitute…

Living without permanent, long-term housing creates a number of stressors for children and families, but being homeless can be particularly detrimental to the healthy development of young children. The National Center on Family Homelessness reports that more than 1.6 million children--or one in 45 children--were homeless annually in America…
