Assessing the PM2.5 impact of biomass combustion in megacity Dhaka, Bangladesh - PubMed (nih.gov)

This article is about crop burning in Dhaka, Bangladesh and attempts to figure out if there is more or less harmful PM2.5 particulate air pollution caused by either fossil fuels or biomass, and during which season is one or the other higher in the air pollution it produces. During monsoon season, fossil fuels lead in the most PM2.5 releases at 44.3%. When it is not monsoon season and is the winter season, the percentages are way higher for PM2.5 air particulate releases at 41.4% for the remainder of the year. Across the globe, there are now people stepping up to uncover the true and real environmental and health impacts this harmful particulate byproduct causes in different parts of the world and with differring weather conditions than what we see in North Carolina. 

Emissions from Biomass Burning in South/Southeast Asia; correcting the miscalculation about the PM2.5 emissions from burning.

This study is set in South/Southeast Asia and uncovering that, when trying to count the percentages of PM2.5 put off during biomass, the true amount of emissions were being gravely undercalculated. Specifically rice straw burning becuase the amount burned varied so much because of different harvest and burning practices that it just wasn't taken into consideration. What this study does is go bottom up using these strategies: "subnational spatial database of rice-harvested area, region-specific fuel-loading factors, region, and burning-practice-specific emission and combustion factors, including literature-derived estimates of straw and stubble burned"(Lasko et al. 2021, 1). 

The Clean Air Act and the EPA laws and regulations against harmful PM2.5 air pollutant matter

The most common air pollutants are called criteria pollutants and are regulated by the Clean Air Act and the EPA. These pollutants are: particles, ozone, nitrogen oxides, sulfer dioxide, carbon monoxide, and lead. The EPA have sections under the CAA that help regulate factories and air pollution in the environment. For example section 108 requires the EPA to identify the pollutants that are criteria pollutants, listed above, and determine if where they are coming from and if they "endander public health or welfare". Under section 109 the EPA had to set standards across the board for air pulltion in regard to human health and to the environemtn sperately (Christopher D. Ahlers 2016, 51-52).  There are many more sections that go into detail about what the CAA can do and what the EPA members are required to do as well.

I am mainly part of the research collective called “COVID-19 Places: Turkey.” I focus on the COVID-19 disaster governance and scientific cultures. So far, we have worked through google docs. By September, we plan to hold regular meetings, and add more to the PECE essay. This group welcomes new members.

I also have many questions at local, national, and transnational levels. Nevertheless, in the short-term (Fall 2020), I want to focus on the following research topics/areas: 

  • The transnational governance of COVID-19

  • The ways science-society relations (and/or scientific cultures) shape and are shaped by the governance of COVID-19 in specific places (from community to institution to city to nation-state scale).

  • Tactics that can be developed through transnational collaboration so as to respond to the various problems deepening and/or emerging in the midst of this disaster, e.g., the problems we (may) encounter as educators, and so on. 

I imagine all these as collaborative studies.

On July 3, Selim Badur has interpreted this report (Açık Radyo - Korona Günleri programme) by drawing attention to "two interesting points":

1. The highest incidences were seen in persons aged 80 years and older but the second cluster includes persons aged 25 to 49 years (49.4%). 

2. In the world, it is said that men are infected more than women. In Turkey, female cases aged 15 to 24 are more than male cases.

Freedom

shortly attaching this news article on "coronavirus lockdown protests" to this reading. should be an obvious one to all. 

Re: the discussion on "our" concepts of freedom

--

Adding a popular quote - from Kafka's "A Report to an Academy

I fear that perhaps you do not quite understand what I mean by "way out." I use the expression in its fullest and most popular sense—I deliberately do not use the word "freedom." I do not mean the spacious feeling of freedom on all sides. As an ape, perhaps, I knew that, and I have met men who yearn for it. But for my part I desired such freedom neither then nor now. In passing: may I say that all too often men are betrayed by the word freedom. And as freedom is counted among the most sublime feelings, so the corresponding disillusionment can be also sublime. In variety theaters I have often watched, before my turn came on, a couple of acrobats performing on trapezes high in the roof. They swung themselves, they rocked to and fro, they sprang into the air, they floated into each other's arms, one hung by the hair from the teeth of the other. "And that too is human freedom," I thought, "self-controlled movement." What a mockery of holy Mother Nature! Were the apes to see such a spectacle, no theater walls could stand the shock of their laughter.

No, freedom was not what I wanted. Only a way out; right or left, or in any direction; I made no other demand; even should the way out prove to be an illusion; the demand was a small one, the disappointment could be no bigger. To get out somewhere, to get out! Only not to stay motionless with raised arms, crushed against a wooden wall.

COVID-19 and Higher Education

Duygu Kasdogan

When I read the commentary on COVID-19 and Higher Education, it reminded me an article published in the early days of the transition to online teaching. In this article entitled "The Difference Between Emergency Remote Teaching and Online Learning," the authors emphasize the importance of naming (what we regularly refer as) online teaching as "emergency remote teaching": 

"Online learning carries a stigma of being lower quality than face-to-face learning, despite research showing otherwise. These hurried moves online by so many institutions at once could seal the perception of online learning as a weak option, when in truth nobody making the transition to online teaching under these circumstances will truly be designing to take full advantage of the affordances and possibilities of the online format."

"Researchers in educational technology, specifically in the subdiscipline of online and distance learning, have carefully defined terms over the years to distinguish between the highly variable design solutions that have been developed and implemented: distance learning, distributed learning, blended learning, online learning, mobile learning, and others. Yet an understanding of the important differences has mostly not diffused beyond the insular world of educational technology and instructional design researchers and professionals. Here, we want to offer an important discussion around the terminology and formally propose a specific term for the type of instruction being delivered in these pressing circumstances: emergency remote teaching."

Let's re-read a quote in the commentary by Robert Pose in the light of above notes: 

"The sudden brutal switch to online learning is the most obvious consequence for higher education of the pandemic. Everyone now accepts online teaching because everyone regards it as necessary to reduce serious health hazards. But after the pandemic recedes, it is likely economic forces will seek to keep online learning in place, because it is far cheaper than education before the pandemic."

I think we need much more nuanced and careful approach to the possibility of continuing online teaching in the aftermath of COVID-19 without reducing the discussion to the terms of economics. Since many universities have shifted to emergency remote teaching without necesarily having the required experience and infrastructure in online teaching, there appear many concerns beyond economics, at least in my university, e.g., the lack of regular communication between students and educators appear as a concern of the authorities beyond of teachers.
