TRB's Transit Cooperative Research Program (TCRP) Report 154: Developing, Enhancing, and Sustaining Tribal Transit Services: A Guidebook offers guidance about the various steps for planning and implementing a tribal transit system. The steps that are described may be used for planning a new transit system, enhancing an existing service, or taking action to sustain services.
The report also provides an overview of the tribal transit planning process.
The project that developed TCRP Report 154 also produced TCRP Web Document 54: Developing, Enhancing, and Sustaining Tribal Transit Services: Final Research Report, which documents the development of the TCRP Report 154.
In addition, the project also produced a 16-page full-color brochure, published in 2011 as "Native Americans on the Move: Challenges and Successes", with an accompanying PowerPoint presentation; and a PowerPoint presentation describing the entire project.

Workshop_in_brief
The online information environment enables the global exchange of information and ideas, but it also contributes to the proliferation of disinformation. Online platforms operate at a scale where human-based content moderation to counter disinformation is impractical or at least very expensive and where purely technical solutions are challenging because content is often context-dependent. The speed, scale, and complexity of this ecosystem suggests that solutions are needed that consider the global nature of disinformation and effectively blend technical and human capabilities.
On April 10 and 11, 2024, an ad hoc committee under the auspices of the National Academies of Sciences, Engineering, and Medicine's Committee on Science, Technology, and Law convened a virtual workshop to consider practicable solutions to counter online disinformation, particularly in social media. This publication summarizes the presentation and discussion of the workshop.

Women in the United States experience a higher prevalence of many chronic conditions, including Alzheimer's disease, depression, and osteoporosis, than men; they also experience female-specific conditions, such as endometriosis and pelvic floor disorders. A lack of research into both the biological and social factors that influence these conditions greatly hinders diagnosis, treatment, and prevention efforts, thus contributing to poorer health outcomes for women and substantial costs to individuals and for society.
The National Institutes of Health's Office of Research on Women's Health asked the National Academies of Sciences, Engineering, and Medicine to convene an expert committee to identify gaps in the science on chronic conditions that are specific to or predominantly impact women, or affect women differently, and propose a research agenda. The committee's report presents their conclusions and recommendations.

A high-quality preschool education can foster critical development and learning that promotes joyful, affirming, and enriching learning opportunities that prepare children for success in school and life. While preschool programs generally provide emotionally supportive environments, their curricula often fall short in advancing learning in math, early literacy, and science, and lack the necessary support for multilingual learners emerging bilingualism. Additionally, access to high-quality, effective early learning experiences may be limited and inadequate based on factors such as a childs race, location, gender, language, identified disability, and socioeconomic status.
A New Vision for High-Quality Preschool Curriculum examines preschool curriculum quality for children from ages three to five, with special attention to the needs of Black and Latine children, multilingual learners, children with disabilities and children experiencing poverty in the United States. The report articulates a vision for high-quality preschool curricula for all children, grounded in an equity and justice-oriented principles from inception to implementation and evaluation.

Experiencing a single disaster - a hurricane, tornado, flood, severe winter storm, or a global pandemic - can wreak havoc on the lives and livelihoods of individuals, families, communities and entire regions. For many people who live in communities in the U.S. Gulf of Mexico region, the reality of disaster is starker. Endemic socioeconomic and health disparities have made many living in Gulf of Mexico communities particularly vulnerable to the effects of weather-climate hazards. Prolonged disaster recovery and increasing disaster risk is an enduring reality for many living in Gulf of Mexico communities. Between 2020 and 2021, seven major hurricanes and a severe winter storm affected communities across the region. As a backdrop to these acute weather events, the global COVID-19 pandemic was unfolding, producing a complex and unprecedented public health and socioeconomic crisis.
Traditionally, the impacts of disasters are quantified individually and often in economic terms of property damage and loss. In this case, each of these major events occurring in the Gulf of Mexico during this time period subsequently earned the moniker of "billion-dollar" disaster. However, this characterization does not reflect the non-financial human toll and disparate effects caused by multiple disruptive events that increase underlying physical and social vulnerabilities, reduce adaptive capacities and ultimately make communities more sensitive to the effects of future disruptive events. This report explores the interconnections, impacts, and lessons learned of compounding disasters that impair resilience, response, and recovery efforts. While Compounding Disasters in Gulf Coast Communities, 2020-2021 focuses on the Gulf of Mexico region, its findings apply to any region that has similar vulnerabilities and that is frequently at risk for disasters.

Factors related to the COVID-19 pandemic contributed to profound disruptions in childhood vaccination schedules and access. While childhood immunization rates have rebounded to nearly pre-pandemic levels, disparities in coverage by race, ethnicity, poverty status, insurance status, and urbanicity persist and, in some cases, have been exacerbated. Addressing these gaps and disparities necessitates multifaceted and targeted interventions, employing robust efforts at the policy, health systems, and provider levels to sustain and increase vaccination rates across diverse populations, along with individual- and community-level strategies aimed at improving vaccine attitudes. A key component of these strategies is building trust with both parent and provider communities at multiple levels, including healthcare, public health, and government agencies involved with approving and recommending vaccines.
Within this framework, this rapid expert consultation identifies strategies for promoting childhood immunization with a particular focus on populations with lower vaccination rates, including Black, Hispanic, and American Indian/Alaska Native children; those living in rural areas; people with lower incomes; and people who lack health insurance. This consultation focuses on targeted strategies for supporting resilient immunization services, addressing access barriers, promoting vaccine confidence and uptake, and providing accurate information while countering misinformation and disinformation.

For more than 75 years, high-hazard structures in the U.S., including dams and nuclear power plants, have been engineered to withstand floods resulting from the most unlikely but possible precipitation, termed Probable Maximum Precipitation (PMP). Failure of any one of the more than 16,000 high-hazard dams and 50 nuclear power plants in the United States could result in the loss of life and impose significant economic losses and widespread environmental damage, especially under the pressures of climate change. While PMP estimates have provided useful guidance for designing critical infrastructure, weaknesses in the scientific foundations of PMP, combined with advances in understanding, observing, and modeling extreme storms, call for fundamental changes to the definition of PMP and the methods used to estimate it.
Modernizing Probable Maximum Precipitation Estimation recommends a new definition of PMP and presents a vision for a methodology relevant for design, operation, and regulation of critical infrastructure. The new definition targets precipitation depths with an extremely low exceedance probability instead of assuming rainfall is bounded, and considers specified climate periods so that PMP estimates can change as the climate changes. Near-term enhancements to PMP include improved data collection, model-based storm reconstructions, and strengthened scientific grounding for PMP methods. Long-term model-based PMP estimation will employ kilometer-scale climate models capable of resolving PMP storms and producing PMP-magnitude precipitation. A Model Evaluation Project will provide scientific grounding for model-based PMP estimation and determine when transition to a model-based PMP estimation should occur. Scientific and modeling advances along this front will contribute to addressing the societal challenges linked to the changes in extreme storms and precipitation in a warming climate, which are critical steps to ensuring the safety of our infrastructure and society.

People with disabilities can be any age, face chronic health conditions or mental illness, be racial or ethnic minorities, experience low income or housing insecurity, have limited English proficiency, or a combination of many of these conditions. To better understand the effect of health inequities and the manner in which they affect Social Security Administration's (SSA) disability programs, the National Academies hosted a public workshop in April 2024 that examined the variety of different experiences of individuals with disabilities and the consequences of those experiences on an individual's health status, medical record, and SSA disability determinations.

Historically, ridership has been the primary way transit agencies have communicated their success and public value in making connections for community. Several transit agencies have shifted services and enhanced performance tracking in recent years in ways that relate to the inequities tied to race, ethnicity, national origin, physical ability, income, age, or gender.

The United States is an important food producer globally, in part because of its abundance of agriculturally productive soils. However, management practices that maximize yields have caused losses in soil organic matter, poor soil structure and water-holding capacity, and increased salinity on millions of acres of land - and have adversely affected the microbial communities that are the drivers of many soil processes. At the same time, recent scientific advances have spurred interest in how microbial communities can support soil health, food quality, and human health.
It is in this context that the U.S. Department of Agriculture National Institute of Food and Agriculture asked the National Academies to explore the linkages between soil health and human health. The report finds that to improve soil health, federal agencies need to promote the importance of soil health, support translational research, and develop a coordinated national approach to monitor soil health over time and space. Given the potential that microbiomes have in modulating soil, plant, and human health, there is also a pressing need to determine which microbial features, if any, contribute to quantifying or fortifying health in both human and soil systems and to understand the direct and indirect roles of soil, alongside other environmental factors, in influencing human microbial colonization and subsequent health outcomes. Such investigation involves delving into the relatively sparse or disconnected research regarding the microbiome continuum that links soil and human systems.

In 2018, the National Academies released Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space. The decadal survey identified key science questions and prioritized observational needs to advance U.S. efforts in Earth science and support critical applications such as climate modeling and weather prediction. In the past few years, the need for actionable data and better scientific information on Earth's interacting systems has increased in urgency, as global climate change accelerates coupled with increasing numbers of extreme weather events.
At the request of NASA, this mid-term assessment evaluates progress and recommends actions to meet decadal survey priorities. This report explores ways that NASA's Earth Science Division can maintain programmatic balance, improve alignment with decadal survey priorities, and prepare for the next decadal survey.
