This highlights the importance of considering social networks in disaster planning for vulnerable communities.
The new H2CAR process produces three times more biofuels from the same biomass, reducing carbon dioxide emissions and increasing efficiency. This could provide sustainable fuel for all US transportation sectors without additional land use.
Researchers will develop software to predict unintended consequences of greenhouse gas reduction policies on the automotive market, life cycle environmental impact, and material demand. The goal is to ensure that policies effectively reduce emissions while minimizing undesirable outcomes.
A new paper from the Journal of Consumer Research distinguishes between narrative and analytical self-referencing in ads. Narrative self-reference almost always leads to favorable evaluations, while analytical self-reference can lead to negative responses if the ad's message is not well-reasoned.
A new study conducted by the University of Texas at Austin found that children's age and family dynamics play a significant role in shaping weekend leisure activity choices. The study reveals that children whose fathers have a higher education level are more likely to engage in active recreation, while those from single-parent househol...
Scientists sequenced the first complete tree genome, poplar, to develop sustainable plantation forestry and biofuels production. The research identified over 45,000 protein-coding genes and 93 genes associated with cellulose production.
A new software tool will help analyze the unintended consequences of environmental regulations on the automotive market and industry life cycle. The project aims to integrate models of market decisions, technological performance, and life cycle assessment to predict the effectiveness of greenhouse gas reduction policies.
Researchers Jing Wang and Bobby Calder found that ads can have both negative and positive effects on advertising. Ads appearing after a story has ended can actually enhance their effect. The study suggests that the timing of ad placement is crucial in determining its impact.
Researchers from Max Planck Institute used data from a popular internet game to analyze banknote movements, finding universal scaling laws that govern human travel behavior. These laws provide insight into the statistical rules governing the spread of diseases.
A survey of 415 senior citizens in Western New York found that more than half faced barriers to seeing a dentist, with finances and anxiety being major concerns. The study suggests that dentists should discuss these barriers with their patients to improve access to dental care.
A study of 34 metropolitan areas found that San Francisco and New York City had high percentages of people who walk or bike for recreation and transportation, respectively. Parkland acreage was also positively associated with walking and bicycling levels, suggesting a link between urban green spaces and physical activity.
A recent study published in the Journal of Air Transport Management found that domestic airline ticket taxes add approximately 15% to average fares, contradicting airline executives' claims. The research analyzed millions of tickets and provides a definitive answer to questions about ticket tax burdens on air travel costs.
A recent MIT study explores the effects of terrorism on global supply chains, highlighting the importance of vulnerability maps and flexible supply chains in minimizing disruption. The research also emphasizes the need for corporate cultures to prioritize communication and security.
The journal celebrates the Wright brothers' achievement with a special issue focusing on the application of operations research in aviation. The studies explore various aspects, including aircraft scheduling, air transport networks, and airspace planning.
A joint project between UDOT, GE Driver Development, and the University of Utah aims to enhance snowplow driver skills using state-of-the-art simulation technology. The training will focus on controlling speed, maintaining tandem position, and communication with other operators in a simulated winter environment.
A protein called huntingtin is critical for normal neuronal transportation, but a defective version causes physical blockage and binding interference, leading to neuronal damage. The study supports the hypothesis that blockage of neuronal transportation contributes to neurodegenerative diseases.
A new report warns that the US air transportation system is in peril due to a lack of coordination among stakeholders. The report calls for a focused national leadership and strategic vision to enable the airline industry to meet increasing travel demand.
