Teaching is a professional craft. Thinking that any high-scoring college student could come in and excel demeans it as a profession. No one would consider letting smart English majors perform surgery on low-income patients, or allowing cum laude math majors to do legal work for poor clients.

Atul Gawande: How Do Good Ideas Spread? : The New Yorker - 36 views
-
Consider the very different trajectories of surgical anesthesia and antiseptics, both of which were discovered in the nineteenth century.
- ...18 more annotations...
-
The idea spread like a contagion, travelling through letters, meetings, and periodicals. By mid-December, surgeons were administering ether to patients in Paris and London. By February, anesthesia had been used in almost all the capitals of Europe, and by June in most regions of the world.
-
On October 16, 1846, at Massachusetts General Hospital, Morton administered his gas through an inhaler in the mouth of a young man undergoing the excision of a tumor in his jaw.
-
Four weeks later, on November 18th, Bigelow published his report on the discovery of “insensibility produced by inhalation” in the Boston Medical and Surgical Journal.
-
There were forces of resistance, to be sure. Some people criticized anesthesia as a “needless luxury”; clergymen deplored its use to reduce pain during childbirth as a frustration of the Almighty’s designs.
-
Yet soon even the obstructors, “with a run, mounted behind—hurrahing and shouting with the best.” Within seven years, virtually every hospital in America and Britain had adopted the new discovery.
-
Sepsis—infection—was the other great scourge of surgery. It was the single biggest killer of surgical patients, claiming as many as half of those who underwent major operations
-
nfection was so prevalent that suppuration—the discharge of pus from a surgical wound—was thought to be a necessary part of healing.
-
In the eighteen-sixties, the Edinburgh surgeon Joseph Lister read a paper by Louis Pasteur laying out his evidence that spoiling and fermentation were the consequence of microorganisms. Lister became convinced that the same process accounted for wound sepsis.
-
Lister had read about the city of Carlisle’s success in using a small amount of carbolic acid to eliminate the odor of sewage, and reasoned that it was destroying germs. Maybe it could do the same in surgery.
-
During the next few years, he perfected ways to use carbolic acid for cleansing hands and wounds and destroying any germs that might enter the operating field.
-
Surgeons soaked their instruments in carbolic acid, but they continued to operate in black frock coats stiffened with the blood and viscera of previous operations—the badge of a busy practice.
-
It was a generation before Lister’s recommendations became routine and the next steps were taken toward the modern standard of asepsis—that is, entirely excluding germs from the surgical field, using heat-sterilized instruments and surgical teams clad in sterile gowns and gloves.
-
Maybe ideas that violate prior beliefs are harder to embrace. To nineteenth-century surgeons, germ theory seemed as illogica
-
The technical complexity might have been part of the difficulty. Giving Lister’s methods “a try” required painstaking attention to detail.

Aspirin stimulates insulin - 6 views
-
AbstractNormal subjects and patients with adult-onset diabetes received 10 gm. of aspirin in four days. On the fourth day, the fasting serum glucose and the glucose response to oral glucose were decreased in both groups. These changes were associated with increased levels of serum insulin and pancreatic glucagon, although the glucagon responses to oral glucose were unchanged. In the diabetic patients, aspirin therapy was followed by a decreased glucose response to I.V. glucose and by the appearance of an early insulin peak, which could not be demonstrated before treatment. Aspirin did not affect the I.V. glucose tolerance in normal subjects, although it did enhance the early insulin peak. A decrease in the fasting levels of free fatty acids was noted in both groups, whereas the fasting level of triglycerides decreased only in the diabetic patients. Cholesterolemia did not change in either group. A few preliminary observations indicate that, in normal subjects, ibuprofen and ketoprofen, two other presumed prostaglandin inhibitors, did not affect fasting glycemia, glucose tolerance, or the insulin response to glucose. No changes were noted after the administration of placebo.

I would think you wouldn't have a stomach lining left if you took that on a daily basis. Also just because it stimulates insulin doesn't mean it is a good thing. Sulfonyureas also overstimulate insulin and there is some thought they lead to beta cell burnout. I think it is better to find things like metformin that make you more sensitive to the insulin you naturally make.

The Coach in the Operating Room - The New Yorker - 37 views
-
I compared my results against national data, and I began beating the averages.
-
the obvious struck me as interesting: even Rafael Nadal has a coach. Nearly every élite tennis player in the world does. Professional athletes use coaches to make sure they are as good as they can be.
-
They don’t even have to be good at the sport. The famous Olympic gymnastics coach Bela Karolyi couldn’t do a split if his life depended on it. Mainly, they observe, they judge, and they guide.

no matter how well prepared people are in their formative years, few can achieve and maintain their best performance on their own.
-
For decades, research has confirmed that the big factor in determining how much students learn is not class size or the extent of standardized testing but the quality of their teachers.
-
So, instead of having students take test after test after test, why don't we just have coaches who observe and sit and discuss and offer suggestions and divide the number of tests we give students in half and do away with half? Are we concerned about student knowledge? student performance? student ability? student growth or capacity for growth? What we really need to identify is what we value!
-

California researchers in the early nineteen-eighties conducted a five-year study of teacher-skill development in eighty schools, and noticed something interesting. Workshops led teachers to use new skills in the classroom only ten per cent of the time. Even when a practice session with demonstrations and personal feedback was added, fewer than twenty per cent made the change. But when coaching was introduced—when a colleague watched them try the new skills in their own classroom and provided suggestions—adoption rates passed ninety per cent. A spate of small randomized trials confirmed the effect. Coached teachers were more effective, and their students did better on tests.
-
they did not necessarily have any special expertise in a content area, like math or science.
-
The coaches let the teachers choose the direction for coaching. They usually know better than anyone what their difficulties are.
-
The conversation with the coach and the coach listening and learning what the teacher would like to expand, improve, and grow is probably the most vital part! If the teacher doesn't have a clue, the coach could start anywhere and that might not be what the teacher adopts and owns. So, the teacher must have ownership and direction.
-
-
teaches coaches to observe a few specifics: whether the teacher has an effective plan for instruction; how many students are engaged in the material; whether they interact respectfully; whether they engage in high-level conversations; whether they understand how they are progressing, or failing to progress.
-
must engage in “deliberate practice”—sustained, mindful efforts to develop the full range of abilities that success requires. You have to work at what you’re not good at.
-
most people do not know where to start or how to proceed. Expertise, as the formula goes, requires going from unconscious incompetence to conscious incompetence to conscious competence and finally to unconscious competence.
-
The coach provides the outside eyes and ears, and makes you aware of where you’re falling short.
-
So coaches use a variety of approaches—showing what other, respected colleagues do, for instance, or reviewing videos of the subject’s performance. The most common, however, is just conversation.
-
“What worked?”
-
“What else did you notice?”
-
something to try.

Good coaches, he said, speak with credibility, make a personal connection, and focus little on themselves.
-
“listened more than they talked,” Knight said. “They were one hundred per cent present in the conversation.”
-
trying to get residents to think—to think like surgeons—and his questions exposed how much we had to learn.
-
one twenty-minute discussion gave me more to consider and work on than I’d had in the past five years.
-
watch other colleagues operate in order to gather ideas about what I could do.
-
routine, high-quality video recordings of operations could enable us to figure out why some patients fare better than others.
-
It’s teaching with a trendier name. Coaching aimed at improving the performance of people who are already professionals is less usual.
-
modern society increasingly depends on ordinary people taking responsibility for doing extraordinary things
-
We care about results in sports, and if we care half as much about results in schools and in hospitals we may reach the same conclusion.

When is it a matter of legitimate and compelling public interest to do something unethical and unprofessional?
-
'Blowing the whistle' on wrongdoing, misconduct or incompetence is usually considered heroic. There have been some celebrated cases in the last couple of years of people who have done it , with mixed success. Nurses and teachers for example, have found themselves in front of disciplinary panels of their professional bodies for taking hidden cameras in to their workplace and secretly filming their clients - the patients and students they believed were getting a poor deal.

UKEdMag: Schools, be patient by @HDHSenglish - 1 views
-
"A lot of schools have jumped on buzz words such as metacognition, mindfulness, mindset etc. There is obviously great merit in all these strategies, however as Carol Dweck has emphasised, in a lot of cases these methods are not always understood by school leaders leading to them not being integrated effectively and sustained. These theories are not fads but in many schools, they don't give these methods the planning, time and evaluation that is required for success of any strategies that will benefit learning. Schools are looking for a quick fix and so latch on to 'new, exciting and popular theories'."

"Engaging a bunch of teenagers after lunch on a Friday afternoon is no mean feat. Only the most seasoned and patient of teachers can pull it off, with a great deal of patience, stamina and effort. Well, not necessarily. There are strategies and ideas that can keep the most demotivated students learning when they don't necessarily realise, and fortunately, Jon Tait has compiled a collection of 100 ideas that can keep secondary pupils engaged in their learning, in any subject, in any school."

Psilocybin (magic mushrooms) - 0 views
-
The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
-
Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities

it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
-
Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
-
In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
-
Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
-
Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
-
Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
-
This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
-
use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
-
augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
-
The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation
-
Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
-
psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
-
propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

Shared Governance Is a Myth - Commentary - The Chronicle of Higher Education - 14 views
-
It takes years of rank and the bittersweet experience of extensive committee service to realize that faculty influence on the operation of the university is an illusion, and that shared governance is a myth.
-
Committees report to administrative officers who are at liberty to accept, reject, or substantially alter faculty recommendations.
-
One would think that faculty senates exercise jurisdiction over a range of college life and policy. In reality, the right of many senates does not extend beyond making recommendations to the president, who is under no obligation to accept them.

A more probable source of this way of doing business is the residue of an old ideal of the university. Such survivals of previous practices are not unusual in social life. Physicians, for example, experience a struggle between two competing understandings of their field: the prevalent view that treating patients is a business, and the residue of the old ideal that it is a calling. Ministers live the same ambiguity. Faculty committees constitute the respect that today's university pays to the old notion that it is a community of students and scholars. The impotence of the committees is acknowledgment that at this time in history, institutions of higher education are business ventures, in certain ways similar to factories.
-
If education is primarily a business, managers hire the faculty. If universities are communities of students and scholars, faculty members hire the managers.
-
The growing disempowerment of the faculty is accelerated by the distance of governing boards from campus processes.
