  • Rho's work is grounded in a social science framework called Fuzzy Trace Theory that was pioneered by Valerie Reyna, a Cornell University professor of psychology and a collaborator on this Virginia Tech project. Reyna has shown that individuals learn and recall information better when it is expressed in a cause and effect relationship, and not just as rote information. This holds true even if the information is inaccurate or the implied connection is weak. Reyna calls this cause-and-effect construction a "gist."

      Fuzzy Trace Theory looks interesting for this, and perhaps many other reasons. I want to learn more about this myself, and I'm wondering if this theory could be put to work in other potential behavioral science projects. What do you think?

  • people who were exposed to higher levels of noise from aircraft were more likely to have a higher body mass index, an indicator for obesity that can lead to stroke or hypertension. The findings highlight how the environment—and environmental injustices—can shape health outcomes
  • self-reported body mass index (BMI)
  • The study is the first to explore a connection between aircraft noise exposure and obesity nationwide in the United States; past studies on this subject have focused on European populations, and results have varied

      It would be interesting to see how these studied varied. I would bet that there are other, stronger factors overlying this effect, and it would be challenging to tease out this signal from other socioeconomic factors, but I very much like this concept.

  • “Prior research has shown that aircraft noise can elevate stress responses and disturb sleep, but there has been mixed evidence of any links with body mass index,” says study lead and corresponding author Matthew Bozigar, assistant professor of epidemiology at OSU and a former postdoctoral associate at SPH. “We were surprised to see a fairly robust link between aircraft noise and higher body mass index among women across the US.”
  • These new findings underscore the role of the environment on one’s risk of chronic disease.
  • Junenette Peters, associate professor of environmental health, and colleagues examined airplane noise exposure and self-reported BMI and other individual characteristics among nearly 75,000 participants living around 90 of the major US airports
  • The team examined aircraft noise levels every five years from 1995 to 2010, using a day-night estimate (DNL) that captures the average noise level over a 24-hour period and applies a 10 dB adjustment for aircraft noise occurring at night, when background noise is low.

      I'm sure there are low-powered data loggers that measure dB that we could plant in various places (varying distances from airports (or other things... even just distances from population centers in general). This would allow us to not only work with and search for correlations between data points already collected, but also to generate more specific data on our own. The human data might not necessarily have to be collected by us. The challenge might be just to find databases that have already been collected for various reasons. Much science is done in this way, where instead of generating a ton of data to analyze, the researcher used previously collected data to ask new and interesting questions of.
  • Although the team acknowledges that BMI is a suboptimal metric, the independent and strong association between more aircraft noise exposure and higher BMI that they observed is notable.
  • “We can only hypothesize about why we saw these regional variations, but one reason may relate to the era of regional development, building characteristics, and climate which may affect factors such as housing age, design, and level of insulation,” says Peters. “Regional differences in temperature and humidity may influence behaviors such as window opening, so perhaps study participants living in the West were more exposed to aircraft noise due to open windows or housing type, which allowed more noise to penetrate.”

      The really interesting work here would be teasing interesting patterns out of really complex data sets. For example, people living near airports typically live in housing that is less expensive due to the lesser desirability of living in that area. That tends to correlate with lower socio-economic status found near airports. However, this is interesting because the major flightpaths to the KCI airport do not exactly line up in this way. For example, three of the school districts in Missouri that line up with KCI runways (Park Hill Schools - where we live, Platte County Schools, Kearney Schools, Smithville Schools, and the northern part of North Kansas City Schools) are all of a higher than average socioeconomic status than outlying areas closer to the city. This is unusual in major metropolitan areas.
  • Previous data suggest that Black, Hispanic, and low-income populations are disproportionately exposed to aircraft noise. The participants in the NHS study groups were primarily White and of mid-level socioeconomic status.

      Again, this is a bit different than around most airports. The area immediately surrounding KCI is rather white and mid-to-upper SES.
  • “We need to study the potential health impacts of environmental injustices in transportation noise exposures alongside other environmental drivers of poor health outcomes” Bozigar says. “There is a lot more to figure out, but this study adds evidence to a growing body of literature that noise negatively impacts health.”

      What other environmental factors can be studied either by direct measurement, or by querying previously-collected data to ask/answer questions about environmental health?

  • Research reveals taking pictures of food isn't just content for our social media feeds, but could be the key to improving people's diets

      I just have a gut feeling that, over time, if you knew you were going to photograph every meal, you would tend to eat less, eat more colorful things, and eat more varied things... so that it would make a better photograph. Each of those elements might just lead to healthier meals over time. Very interesting. It is sort of like imposing a metacognitive approach to food selection.

  • The previously hidden and diverse underwater acoustic world in British ponds has been revealed by a team of researchers at the University of Bristol.

      So... my immediate thought is: How cool would it be to do this here? One thing we DO have: PONDS. See if this *sounds* interesting. Get it? ;)
  • Acoustic monitoring has been shown to effectively survey birds and monkeys in rainforests, and marine mammals in the oceans. However, freshwater environments have remained largely unexplored despite their diverse soundscapes.

      BOOM. Again, "relatively unexplored" is super exciting verbiage to me. Acoustics. Hydrophones. Is this feasible? Is the equipment affordable? If not, could we borrow one? Dig into it. What are the possibilities?
  • analysis of the audio files revealed clear daily acoustic activity cycles in each pond

      Aside from the exploratory surveys you would do just to see "what's out there" and assess what we CAN learn from listening to a pond, you could make it experimental by comparing ponds you've assessed the health of by other means. In other words, do acoustic comparisons between two ponds correlate with what you find by doing a macroinvertebrate sampling? I really LIKE the possibilities in this one!

  • Typically, a nocturnal chorus is made by aquatic insects that compete to attract mates by producing strange scratching sounds as they rub their genitals against their abdomens. During the daytime, however, aquatic plants dominate the underwater orchestra with rhythmic whining and ticking sounds produced as tiny oxygen bubbles are released by plants respiring in the hot sun.
  • Using this acoustic method, the presence of species, and a determination of ecological health, can be inferred simply by listening to the natural world without disturbing the environment or harming the plants and animals within it.

      Here is the obvious value proposition if you could work this out.

    This is an interesting possibility for working with large (already-existing) datasets to map out and correlate data about the spring reset for plants. What factors are most important in when the spring "greenup" starts? Could also be combined with some local data collected to compare the datasets with what we are seeing on the ground. Could also be a cool opportunity to use ArcGIS tools for spatially mapping information geographically over time!
