It's 2021! Time for a crash course in four terms that I often see mixed up when people talk about testing: sensitivity, specificity, positive predictive value, negative predictive value.

These terms help us talk about how accurate a test is, but from different viewpoints. 1/

Now, what exactly is an applied epidemiologist, and why are they needed? In the late 90s- early 2000's there were a series of articles in AJPH, AJE, JECH, and IJE dedicated to answering these questions. I'll focus on Stephen Thacker's review.

He states, “The applied epidemiologist is by definition an activist, moving rapidly from findings to policy, putting epi knowledge to good use. The 21st century epi must do all these things while maintaining a foundation of high-quality epi research and practice.”

Susser warns the field of what he considers “the black box paradigm… the current international focus on risk factor epidemiology.” He advocates for expanding our academic training to include socializing epis to “keep the improvement of the public’s health as a primary value”

Morabia argued that epidemiology has historically found its balance in the tension between the search for causal relations and the improvement of public health; overemphasis on either perspective puts epidemiology at risk of losing its value.

How does this play out in real life? I’ve been an applied epi for 13 years, working mainly in local, state, and federal health agencies. My work has focused on conducting cool analysis that lead to policy or systemic change.

Newlane University Manifesto--12 tenets: 1. Education should be available and accessible to every person on earth; making quality education inaccessible or exclusive is immoral. Education belongs in the same category as shelter, clean water, and basic food.

2. Education should be disconnected from geography. Students should be able to learn anything from anywhere on earth. With few exceptions, tying education to geography is a form of exclusion.

3. Education should be disconnected from a schedule. The most effective time to learn something is when the student is ready, not when the teacher or institution is available.

4. Education should not be admission- or permission-based, but freely available upon the asking. The current admission-based system is a vestige of a scarcity model that could only fit a limited number of seats in a classroom.

(4 continued) No one should have to be admitted or ask permission to learn a subject.

SCOOP: Seattle Public Schools tells teachers that the education system is guilty of “spirit murder” against black children and that white teachers must “bankrupt [their] privilege in acknowledgement of [their] thieved inheritance.”

Let's review the whistleblower documents.👇

The trainers begin by claiming that teachers are colonizers of Native American "ancestral lands" and that “the United States was built off the stolen labor of kidnapped and enslaved Black people’s work, which created the profits that created our nation.”

The participants identify themselves by both gender pronouns and race labels. While it has become commonplace in academia to use gender pronoun identifiers, this is perhaps the first example of an institution creating the expectation for explicit race-labeling in the workplace.

The trainers tell white teachers that they "must commit to the journey" of anti-whiteness, even if their "lizard-brain" makes them "afraid that [they] will have to talk about sensitive issues such as race, racism, classism, sexism, or any kind of ‘ism.’"

The central message is that white teachers must recognize that they “are assigned considerable power and privilege” because of their “possession of white skin.” To atone for this guilt, they must “bankrupt [their] privilege in acknowledgement of [their] thieved inheritance.”

This open letter created a false dichotomy in the schools debate, pitting MH against safety. Thread..

We are saddened that the signatories of the letter do not appear to have channelled their energy into encouraging innovation in distance learning and support which could serve to bolster children's mental health in order to limit some of harms caused by isolation.

That the potential for the Internet to be used as a "fantastic communications tool" and provide "a creative and visual style of learning" affording "a positive and interactive experience" as identified by @ProfTanya in the Byron Review has not been celebrated is a travesty.

The report identified the internet to be a platform for children and young people to "express themselves and keep in touch" and is "a fantastic place to meet people and find support, friendship and

When we consider that internet based interventions such as iCBT are now well established psychological practice, it is a great sadness that the expertise of professionals in this field has not been channelled toward helping craft a recovery curriculum children desperately need

1/ A thread on why universities need to keep teaching online for the rest of this term.

2/ The government's last guidance to universities was issued on 3 February. It instructed HE providers not to offer any face-to-face teaching - outside exempt subjects such as medicine, dentistry and veterinary science - until at least 8 March.

3/ By the time the guidance was issued, 12 universities and colleges had already announced that they were keeping non-exempt teaching online until the end of this term or semester. Since then 3 more have done so, and another is keeping teaching online until at least 26 April.

4/ See

5/ On Monday the government is expected to issue new guidance. Based on their past guidance documents, they may well say that HE providers can start offering face-to-face teaching to certain groups of students from 8 March, but to other groups not until later dates.
