Stronger Regulations On Air Pollution Could Reduce Cardiovascular Disease Mortality Rates, 2023 Syracuse University
Stronger Regulations On Air Pollution Could Reduce Cardiovascular Disease Mortality Rates, Yue Sun
Center for Policy Research
Cardiovascular disease (CVD) is the leading cause of death in the United States, but there are large disparities in CVD death rates across the country. Air pollution also plays an important role in shaping geographic disparities in CVD mortality, as air pollutants can become absorbed in human circulation systems, and cause inflammation, damage nervous systems, and trigger poor CVD outcomes. This brief reports the results of a study that used data on air pollution and from death certificates to estimate the association between fine particulate matter and cardiovascular disease mortality rates in the U.S. in 2016-2018. Results show that cutting …

The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales
School of Natural Resources: Dissertations, Theses, and Student Research
Nebraska’s agricultural landscapes are rapidly changing, affecting natural resources and their successful management. I utilized two surveys and scenario planning (Chapters 1: statewide survey, 2: local survey, and 3: scenario-planning workshop) to investigate attitudes and perceptions of natural resource management and cross-boundary collaboration. My first objective focused on determining what prevents Nebraskans from addressing natural resources challenges, considering demographics amongst generations and the type of areas they live in (rural versus urban). The second objective focused on whether landowners engaged with their community in managing natural resources. The third objective was to develop alternative future scenarios for the Denton Hills …
