    1. A 2016 Lancet study found that universal breast-feeding would prevent 800,000 child deaths a year across the globe and yield $300 billion in savings from reduced health care costs and improved economic outcomes for those reared on breast milk.

      Pure corruption here. Protectionism to prop up profits of approximately 630 million versus major benefits and savings of 300 billion. Even if you look at the calculus of the entire industry of 70 billion it becomes a no brainer.

    1. She reached behind her to her bookshelf, which held about a dozen blue bottles of something called Real Water, which is not stripped of “valuable electrons,” which supposedly creates free radicals something something from the body’s cells.

      I question her credibility to market claims like this. I suspect she has no staff scientist or people with the sort of background to make such claims. Even snake oil salesmen like Dr. Oz are pointedly putting us in hands way too make a buck.

    1. many Indians continue to defecate in the open. Bangladesh’s government and charities have built latrines, too, but they have worked harder to stigmatise open defecation. Often they install latrines for the poor and then prod richer folk into following their example. A new, surprising, finding is that this works better than expecting people to copy their social superiors.
    2. Many lives have been saved by parents doing something simple. Beginning in the 1960s American military doctors and researchers in Dhaka developed a therapy for acute diarrhoea—a sweet, salty oral rehydration solution. This is now dirt cheap and widely available. At the last count, fully 84% of Bangladeshi parents with stricken children fed it to them (only a third saw a doctor). Thinly populated African countries are struggling to match that. One promising idea is to distribute the sachets along with Coca-Cola—which gets everywhere.

      amazing the reach of Coca-Cola!

    1. To find a cure for what ails America, Chetty will need to understand all of this wild variation. Which factors foster opportunity, and which impede it? The next step will be to find local interventions that can address these factors—and to prove, with experimental trials, that the interventions work

      I suspect that racial inequalities like Redlining, school support, and public housing issues (including evictions and predatory lending) will overlay these unmobile areas. cf Scarlet E series from On the Media.

    1. How this phenomenon translates into absolute, rather than relative, risk, however, is a bit thorny. A large study published in 2018, for instance, found that among women who had children between 34 and 47, 2.2 percent developed breast cancer within three to seven years after they gave birth (among women who never had children, the rate was 1.9 percent). Over all, according to the American Cancer Society, women between 40 and 49 have a 1.5 percent chance of developing breast cancer.

      The rates here are so low as to be nearly negligible on their face. Why bother reporting it?

    1. They’re mostly things that everyone was supposed to be doing all along, such as ensuring that bathrooms have exhaust fans and that air filters are changed regularly and of high-enough quality to catch the virus. That means they should be high-efficiency particulate air (HEPA) filters or MERV-rated 13 or 14, which are essentially the N-95 masks of air filters.
    1. “We ought to have a social compact: If you’re sick, whether you’ve got Covid-19 or not, you should separate yourself from society,” Mr. Gostin said. “That’s your part of the bargain, you’re doing it for your neighbors, your family and your community.”“In exchange,” he said, “we as a nation owe you the right to a humane period of separation, where we meet your essential needs like medicine, health care, food and sick pay.”
    1. Reporting on a study at Queensborough Community College, also in the CUNY system, Sheila Beck notes that the library’s reserve textbook collection is “heavily used,” however, staffing and other concerns have prompted librarians to consider “less labor intensive and less costly alternatives.“ Beyond textbook reserves, academic librarians can help students to locate required course readings in other ways: older editions of their required textbook, pre- or post-prints of articles in institutional repositories, articles or other texts in databases subscribed to by the library, or readings that may be in the public domain or otherwise available on the open web.

      The basic economics of this system would indicate (especially as classes become larger and larger) that more careful consideration of choice, economics, accessibility, availability, etc. on a larger institutional level creates larger marginal gains for those in the class. If a staff librarian, teacher, or someone else within the system does the leg-work up front and does it well, then the dozens or even hundreds of students in the course don't need to spend (read: waste) their own time re-inventing the proverbial textbook wheel once they're in the class.

      Portions of the situation here make me wonder if we might pull a page from Dr. Peter Pronovost's playbook in the health care space and create a simple checklist of what to do when planning for textbooks and readings. Checklists that include things like:

      • will the texts actually be used?
      • will they be primary to the subject or are they supplementary?
      • What are their prices?
      • Are alternate materials available?
      • Are older editions available?
      • are public domain or open web versions available?
      • are there copies in the library? reserves? pirated versions? pre/post prints?
      • etc.

      Once such a checklist is available, institutions should require that it be available along with syllabi and other course listings.

    1. Most of the actual texts in the Heath were public domain texts, freely available and not under any copyright restrictions.  As the Heath produced new editions (of literature from roughly 1400-1800!), forcing students to buy new textbooks or be irritatingly out of sync with page numbers, and as students turned to rental markets that necessitated them giving their books back at the end of the semester, I began to look in earnest for an alternative.

      Repackaging public domain texts and charging a steep markup too much above and beyond the cost of the paper is just highway robbery. Unless a publisher is adding some actual annotative or analytical value, they shouldn't be charging outrageous prices for textbooks of this nature.

    1. “Imagery in public space is a reflection of who has the power to tell the story of what happened and what should be remembered,” Bleiberg said. “We are witnessing the empowerment of many groups of people with different opinions of what the proper narrative is.” Perhaps we can learn from the pharaohs; how we choose to rewrite our national stories might just take a few acts of iconoclasm.
    1. To summarize his argument, the media industry wants to broaden our definition of the public so that it will be fair game for discussion and content creation, meaning they can create more articles and videos, meaning they can sell more ads. The tech industry wants everything to be public because coding for privacy is difficult, and because our data, if public, is something they can sell. Our policy makers have failed to define what’s public in this digital age because, well, they don’t understand it and wouldn’t know where to begin. And also, because lobbyists don’t want them to.
    1. Is it possible to avoid the public goods problem altogether?

      As Lynne Kelly indicates, knowledge is a broad public good, so it is kept by higher priests and only transferred in private ceremonies to the initiated in indigenous cultures. In many senses, we've brought the value of specific information down dramatically, but there's also so much of it now, even with writing and better dissemination, it's become more valuable again.

      I should revisit the economics of these ideas and create a model/graph of this idea over history with knowledge, value, and time on various axes.

    2. Put another way, many tools for thought are public goods. They often cost a lot to develop initially, but it’s easy for others to duplicate and improve on them, free riding on the initial investment. While such duplication and improvement is good for our society as a whole, it’s bad for the companies that make that initial investment. And so such tools for thought suffer the fate of many public goods: our society collectively underinvests in them, relative to the benefits they provide
    1. CDC reverses course on testing for asymptomatic people who had Covid-19 contact

      Take Away

      Transmission of viable SARS-CoV-2 RNA can occur even from an infected but asymptomatic individual. Some people never become symptomatic. That group usually becomes non-infectious after 14 days from initial infection. For persons displaying symptoms , the SARS-CoV-2 RNA can be detected for 1 to 2 days prior to symptomatology. (1)

      The Claim

      Asymptomatic people who had SARS-CoV-2 contact should be tested.

      The Evidence

      Yes, this is a reversal of August 2020 advice. What is the importance of asymptomatic testing?

      Studies show that asymptomatic individuals have infected others prior to displaying symptoms. (1)

      According to the CDC’s September 10th 2020 update approximately 40% of infected Americans are asymptomatic at time of testing. Those persons are still contagious and are estimated to have already transmitted the virus to some of their close contacts. (2)

      In a report appearing in the July 2020 Journal of Medical Virology, 15.6% of SARS-CoV-2 positive patients in China are asymptomatic at time of testing. (3)

      Asymptomatic infection also varies by age group as older persons often have more comorbidities causing them to be susceptible to displaying symptoms earlier. A larger percentage of children remain asymptomatic but are still able to transmit the virus to their contacts. (1) (3)

      Transmission modes

      Droplet transmission is the primary proven mode of transmission of the SARS-CoV-2 virus, although it is believed that touching a contaminated surface then touching mucous membranes, for example, the mouth and nose can also serve to transmit the virus. (1)

      It is still unclear how big or small a dose of exposure to viable viral particles is needed for transmission; more research is needed to elucidate this. (1)

    1. The Indian government is pushing a bold proposal that would make scholarly literature accessible for free to everyone in the country

      "... accessible for free ..."

      open access sampai hari ini memang hanya diartikan sebagai membuat artikel ilmiah dapat diunduh dengan membayar APC atau dikenal sebagai modus Gold OA.

      Artikel oleh Peter Suber ini menjelaskan bahwa OA tidak hanya bisa dilakukan melalui jurnal Gold OA.
