“Since asthma surveillance data were not available at the census tract level for most of Louisiana, we estimated asthma burden using the inpatient discharge data available through LDH.”  (4)

“Case counts are not provided for CTs with a 2018 population of less than 800 to safeguard privacy.” (4)

“To minimize the need for suppression, inpatient discharge data was aggregated for the three most recent years available (2017–2019) and average annual crude rates were calculated for cases where asthma (ICD-10 code J45) was the primary diagnosis, as well as where asthma was any diagnosis.” (4)

“Spearman’s Rank Correlation was utilized to analyze the correlation between various social and environmental vulnerability factors, COVID-19 incidence, and the measures of asthma risk by CT.” (4)

“This was performed by first ranking the values in each dataset using RANK.AVG function in MS Excel 2016, followed by applying the PEARSON function to compare two datasets. Significance was set at alpha less than 0.05 (α < 0.05), with degrees of freedom (df) equal to two less than the total number of data points represented in both datasets” (4)

The research team works for the Section of Environmental Epidemiology and Toxicology, Office of Public Health, Louisiana Department of Health in Baton Rouge. Team members included Arundhati Bakshi; Shanon Soileau; Collete Stewart; Kate Friedman; Collete Maser; Alexis Williams; Kathleen Aubin; and Alicia Van Doren. 

“Currently, much of the environmental focus of the pandemic remains on PM2.5 levels; however, we noted that higher levels of ozone was consistently associated with higher incidence rates of COVID-19, and it was the only environmental factor that appeared to have an additive effect over SVI on COVID-19 incidence (Fig 1).” (11)

“Specifically, our data show a moderately strong positive correlation between SVI due to minority status/language barrier and three health data variables: asthma hospitalization; estimated asthma prevalence; and cumulative COVID-19 incidence at 3 months (Table 2). Interestingly, SVI measures were either negatively or not significantly correlated COVID-19 incidence at the 9-and 12-month time points, indicating that social vulnerability factors may have played a greater role in COVID-19 spread early in the pandemic, but may have been of diminishing importance as the pandemic wore on (Fig 1 and Table 2).” (9)

This document uses data resources from the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), the Environmental Protection Agency (EPA), and the Louisiana Department of Health (LDH).

These data resources include the Social Vulnerability Index (2018 - CDC/ATSDR), the NATA Respiratory Hazard Index (EPA 2014), PM2.5level (average annual concentration in ug/m3, EPA 2016), ozone level (summer seasonal average of daily maximum 8-hour concentration in air in parts per billion, EPA 2016), indoor mold concerns reported to IEQES program (average annual number of calls, LDH 2017-2019), cumulative COVID-19 incidence rate at 3-, 6-, 9- and 12-month increments (LDH March 2020 - March 2021), asthma hospitalization (average annual crude rate, where asthma was a primary diagnosis among hospitalization cases, LDH 2017-2019), and estimated asthma prevalence (average annual crude rate, where asthma was any diagnosis among hospitalization cases, LDH 2017-2019).

The web platform appears to be a space to compile stories and information from Hurricanes Katrina and Sandy. The primary goal seems to be informing the public about the hurricanes, specifically the aftermath in the days and months following the flooding. It serves as a method of remembrance for what occurred (the flooding, death toll, lack of appropriate and timely response, the struggles of survivors) and as a way to warn that these problems will continue to occur in the future. In the last few days, Hurricane Matthew ravaged the Caribbean, South Carolina, Georgia, and Florida. It will take weeks to return power to all who have lost it, and exact damage tolls will take months to compile. Although each time, with each pass of destruction, our responses seem to be improving, the disasters continue to accumulate-- despite warnings such as this site. 

It's unclear who, at this time, primarily views and utilizes the information presented here. However, this web platform seems to be one piece of an ongoing project called "Land of Opportunity". This film discusses the ongoing urban issues and developments in America; as we move forward from disasters and begin rebuilding, the question becomes how we want to fortify our cities. The film itself specifically focuses on Hurricane Katrina, while the interactive web platform inclides information about Hurricane Sandy. The film has had several showings, has DVD's for purchase, and a viewing request can also be made.

The creators of the platform and film are part of a C3 non-profit called NOVAC-- New Orleans Video Access Center. There are several organizational partners that work on the ground accomplishing the organization's goals. These partners also provide a measure of funding; as a non-profit, most of the support comes from outside donations, either to the organization or through one of their proxy groups.

The system allows for compilation and continued monitoring of the aftermath of these hurricanes. The platform also provides access to the film and organization following those still effected by the disasters years later. It also serves as an area for conversation and discussion for how to mitigate the effects of disasters in the future.

The data primarily manifests in visual prompts. The web platform begins by engaging the viewer with clips, pictorals, gifs, and interviews discussing the hurricanes from start to finish.

The platform itself allows for discussion and viewing of multiple segments. The associated organization allows for request of public viewing of the overall film; moreover, the overarching organization (and its web platform) allow for discussion on the page itself, with input from users and contact directly to the film makers and organizers

I can only presume through black magic, as I have no idea how technology works
