Exploring The Spatial Distribution Of Air Pollutants And Covid-19 Death Rate: A Case Study For Los Angeles County, California, Akhil Mandalapu, Junfeng Jiao, Amin Azimian

International Journal of Geospatial and Environmental Research

Objective

Since March 2020, COVID-19 has rapidly spread across the world with over 240 million cases and over 5 million deaths as of November 2021. It has been unclear what role air pollutants may play in exacerbating respiratory illnesses such as COVID-19 due to their interaction with the respiratory system. The association with air pollutants and COVID-19 severity has been explored at the regional and metropolitan area, however it is unclear if such an association is consistent at the neighborhood level.

Methods

Weekly death rates from COVID-19 from March 2020 to November 2021 were compared using one-sided unpaired t-tests across ...


Stakeholder Perceptions Of Microplastics Management In Oregon, Maya A. Hurst-Mayr May 2022

Stakeholder Perceptions Of Microplastics Management In Oregon, Maya A. Hurst-Mayr

Student Research Symposium

There is currently no federal policy in the United States that specifically addresses microplastics (MPs) pollution. However, states are beginning to act on this issue; California’s SB 1422 initiates measurement of MPs in drinking water resources and Senate Bill 1263 requires the state to adopt a strategy to reduce the ecological impact of MPs in marine ecosystems. Other West Coast states like Oregon and Washington are expected to follow California’s example. It is important to know what the actors who are a part of shaping MPs policy in Oregon would see as barriers and opportunities to doing so ...

Crises of climate breakdown, ocean acidification, mass extinction, pollution and other forms of environmental degradation demand global transformation. Direct and clinical social workers are on the front lines of responses to the social consequences of these crises. They have critical skills needed for socially and environmentally sustainable solutions to these problems. Yet for the most part, direct and clinical social workers are not engaged in environmental action and do not see their work as “environmental social work.” Micro-level workers need information and resources in order to integrate environmental health in practice, and particularly tools which center the needs of the ...

Understanding California's 2022 Energy Code: Blog 1, Gabriella Medina, Darbi Berry

San Diego Regional Climate Collaborative

When thinking about the built environment, it is easy to overlook the influence structures have on our communities' quality of life. Buildings are relics of the past or symbols of modernity. They are tangible evidence of our society's investment in people's health, the environment and a resilient economy. Buildings play a crucial role over energy usage, urban heat impacts, and overall greenhouse gas emissions.

Deforestation For Pasture Development – Has It Been Worth It?, W. H. Burrows Dec 2021

Deforestation For Pasture Development – Has It Been Worth It?, W. H. Burrows

International Grassland Congress Proceedings

Differing scenarios leading to deforestation for pasture development in savanna (woodland) and closed forest communities in the tropics – sub-tropics are compared and contrasted. Australian and Brazilian examples are highlighted. No simple answer is given to the question of whether deforestation for pasture development has been worth it, since both commercial and non-commercial values have equal validity and need to be taken into account. These issues are addressed in the context of land assigned by governments for agricultural purposes. It is concluded that technology and ecological understanding are now available to maintain sustainable production from converted forest systems. However emphasis should ...

A 60- Year Record Of The Demotechnic Index Of States, 1960-2019, Gavin James Kellough

Graduate Theses and Dissertations

A country’s dependency on energy resources can be interpreted through the calculation of energy indices. The Demotechnic Index (DI) was used to determine the trajectory of energy efficiency of each state in the United States over the period 1960-2019. The DI serves as a measure of the energy intensity of states and a proxy for energy sustainability of each state.The DI is the ratio of total energy use to total metabolic energy demand of a population. Mathematically, DI = (E_T-E_M)/E_M E_T represents the total energy used (metabolic energy + technological energy in kilojoules annually, kJ/y), while EM represents ...

Management Changes And Strategies To Improve The Environmental Services From Grasslands In Northern China And Mongolia, David R. Kemp, J. Addison, K. Behrendt, G. Udval, D. Lkhagvaa, Guodong Han, Zhiguo Li, P. Li

International Grassland Congress Proceedings

The grasslands of Mongolia and northern China are part of the vast Eurasian grasslands that extend from east Asia to eastern Europe, with many common problems. Grassland degradation and herder livelihoods in the steppe regions of China and Mongolia are widely acknowledged as major issues that need to be improved. The core problem is too many animals are now grazing grasslands, initially driven by significant policy changes, and decisions that assumed more animals would lift herder incomes. Problems are accentuated by poorly defined property rights over the land. The effectiveness of current Government Programs aimed at reducing grazing pressures has ...

Learning From The Seed: Illuminating Black Girlhood In Sustainable Living Paradigms, Toni Powell Powell Young Jul 2021

Learning From The Seed: Illuminating Black Girlhood In Sustainable Living Paradigms, Toni Powell Powell Young

Graduate Theses and Dissertations

The contemporary image of sustainable living presents a culturally narrow view of its participants and the manner of engaging in sustainable living paradigms. Through crystallization (Ellingson, 2009) I present a mixed methods approach that emphasizes participant observation, visual, mediated, and discursive analyses, as well as demonstrates the efficacy of Culture Centered Black Feminist Auto/Ethnography. This project seeks to highlight and place within historical context, the ways in which African American girls, who are largely left out of the prevailing image of sustainability, perform and articulate sustainability for themselves, in their homes, and throughout their home communities.

What Spatial Environments Mean, Thora Tenbrink Jul 2021

What Spatial Environments Mean, Thora Tenbrink

Journal of Spatial Information Science

Language is one of the most prominent means of representing human thought. Spatial cognition research has made use of this fact for decades, exploring how humans perceive and understand their spatial environments through language analysis. So far, this research has mainly focused on generic cognitive aspects underlying everyday purposes such as knowing where objects are, how they relate to each other, and how to find one's way to a familiar or unfamiliar location. However, human concepts about space can be threatened by change, as the environment changes. Across the globe, people become increasingly aware of climate-change related threats to ...
