Glenn Beck Doesn't Get It

Question: What is your problem with Glenn Beck?

James Martin: Glenn Beck’s comment really betrayed a fundamental understanding of the gospel. Jesus in the 25th chapter of the Gospel of Matthew basically says that the litmus test for how we’re going to be judged at the end of our lives is not what church we pray in, how we pray, even how often we go to church.  It’s how we treat the poor.  I mean it’s pretty cut and dry.  If you want to enter to heaven, treat the poor well.  Now social justice is a way of looking at what keeps people poor and as the church in its 2,000 year history has reflected on Jesus’ commandment to serve the poor and love the poor it has realized that we need to look at what keeps them poor.  It’s not enough to give someone a handout. It’s important to look at what keeps the people poor, so someone told me the other day the gospel story of the good Samaritan where the guy sees someone by the side of the road who has been beaten and he takes care of him.  He brings him back to an inn.  He dresses his wounds.  He gives him money for staying overnight in the inn.  Someone said to me today we’d also be looking at why that road is dangerous.  What is it that makes that road dangerous?  How can we fix the situations that lead for crime and things like that?  So that is what social justice is.  It’s basically working for a just society.  Now how anybody can be against that is beyond me frankly.  He compared people who support social justice to Stalin and Hitler and I just found that frankly, outrageous.

There have been people other than me that have talked about this and he has responded by saying, “Well I didn’t mean this.”  “What I meant was this.”  “I meant that charity is okay as long as it’s not sponsored by the government.”  But once again, how else does the community respond socially other than through governmental policies?  You can do things individually.  You can do things in church, but I mean we have all sorts of public works in terms of social security and Medicare and Medicaid and public transportation. That, in a sense, is providing for the common good, so I still think he basically just doesn’t like the idea of helping the poor. I think often times this critique of social justice is really just a thinly veiled excuse for not wanting to deal with the poor and a lot of people find the poor as Pope John Paul said, irksome intruders into our comfortable life. But what good is the gospel if it doesn’t disturb you?  It’s supposed to disturb you.

Does conscious AI deserve rights?

If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.

  • Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
  • Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
  • One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.

  • Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
  • The blend of three polymers provides enough flexibility and durability to mimic the knee.
  • The next step is to test this hydrogel in sheep; human use can take at least three years.

Hints of the 4th dimension have been detected by physicists

Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.

Predicting PTSD symptoms becomes possible with a new test

An algorithm may allow doctors to assess PTSD candidates for early intervention after traumatic ER visits.

Technology & Innovation
  • 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
  • Early treatment is available but there's been no way to tell who needs it.
  • Using clinical data already being collected, machine learning can identify who's at risk.

The psychological scars a traumatic experience can leave behind may have a more profound effect on a person than the original traumatic experience. Long after an acute emergency is resolved, victims of post-traumatic stress disorder (PTSD) continue to suffer its consequences.

In the U.S. some 30 million patients are annually treated in emergency departments (EDs) for a range of traumatic injuries. Add to that urgent admissions to the ED with the onset of COVID-19 symptoms. Health experts predict that some 10 percent to 15 percent of these people will develop long-lasting PTSD within a year of the initial incident. While there are interventions that can help individuals avoid PTSD, there's been no reliable way to identify those most likely to need it.

That may now have changed. A multi-disciplinary team of researchers has developed a method for predicting who is most likely to develop PTSD after a traumatic emergency-room experience. Their study is published in the journal Nature Medicine.

70 data points and machine learning

Study lead author Katharina Schultebraucks of Columbia University's Department Vagelos College of Physicians and Surgeons says:

"For many trauma patients, the ED visit is often their sole contact with the health care system. The time immediately after a traumatic injury is a critical window for identifying people at risk for PTSD and arranging appropriate follow-up treatment. The earlier we can treat those at risk, the better the likely outcomes."

The new PTSD test uses machine learning and 70 clinical data points plus a clinical stress-level assessment to develop a PTSD score for an individual that identifies their risk of acquiring the condition.

Among the 70 data points are stress hormone levels, inflammatory signals, high blood pressure, and an anxiety-level assessment. Says Schultebraucks, "We selected measures that are routinely collected in the ED and logged in the electronic medical record, plus answers to a few short questions about the psychological stress response. The idea was to create a tool that would be universally available and would add little burden to ED personnel."

Researchers used data from adult trauma survivors in Atlanta, Georgia (377 individuals) and New York City (221 individuals) to test their system.

Of this cohort, 90 percent of those predicted to be at high risk developed long-lasting PTSD symptoms within a year of the initial traumatic event — just 5 percent of people who never developed PTSD symptoms had been erroneously identified as being at risk.

On the other side of the coin, 29 percent of individuals were 'false negatives," tagged by the algorithm as not being at risk of PTSD, but then developing symptoms.

Going forward

Schultebraucks looks forward to more testing as the researchers continue to refine their algorithm and to instill confidence in the approach among ED clinicians: "Because previous models for predicting PTSD risk have not been validated in independent samples like our model, they haven't been adopted in clinical practice." She expects that, "Testing and validation of our model in larger samples will be necessary for the algorithm to be ready-to-use in the general population."

"Currently only 7% of level-1 trauma centers routinely screen for PTSD," notes Schultebraucks. "We hope that the algorithm will provide ED clinicians with a rapid, automatic readout that they could use for discharge planning and the prevention of PTSD." She envisions the algorithm being implemented in the future as a feature of electronic medical records.

The researchers also plan to test their algorithm at predicting PTSD in people whose traumatic experiences come in the form of health events such as heart attacks and strokes, as opposed to visits to the emergency department.
