FBI arrests spotlight lessons learned after Charlottesville (opinion) - CNN - 0 views

shared by katherineharron on 19 Jan 20 - No Cached
  • On Thursday, the FBI arrested three men, Patrik J. Mathews, 27, Brian M. Lemley Jr., 33, and William G. Bilbrough IV, 19, with firearms charges, and they had plans, an official said, to attend a Virginia pro-gun rally. This followed Virginia Gov. Ralph Northam's declaration of a temporary state of emergency after authorities learned that extremists hoped to use the anti-gun control rally planned next Monday -- Martin Luther King, Jr. Day -- to incite a violent clash.
  • These arrests add to mounting evidence that a decades-old and violent white-power movement is alive and well, perhaps even gaining strength. White power is a social movement that has united neo-Nazis, Klansmen, skinheads, and militiamen around a shared fear of racial annihilation and cultural change. Since 1983, when movement leaders declared war on the federal government, members of such groups have worked together to bring about a race war.

  • Silver linings aside, it will take many, many more instances of coordinated response to stop a movement generations in the making. In more than a decade of studying the earlier white power movement, I have become familiar with the themes of underground activity that are today clearly drawing from the earlier movement. In the absence of decisive action across multiple institutions, a rich record of criminal activity and violence will continue to provide these activists with a playbook for further chaos.
  • The Base, furthermore, is what experts call "accelerationist," meaning that its members hope to provoke what they see as an inevitable race war. They have conducted paramilitary training in the Pacific Northwest. Both of these strategies date back to the 1980s, when the Order trained in those forests with hopes of provoking the same race war.
  • One of the men arrested Thursday was formerly a reservist in the Canadian Army, where he received training in explosives and demolition, according to the New York Times. This kind of preparation, too, is common among extremists like these. To take just a few representative examples, in the 1960s, Bobby Frank Cherry, a former Marine trained in demolition, helped fellow members of the United Klans of America to bomb the 16th Street Birmingham Baptist Church, killing four black girls.
  • This news out of Virginia shows that there is a real social benefit when people direct their attention to these events -- and sustain the public conversation about the presence of a renewed white-power movement and what it means for our society.

  • I often joke that every cable news show should be forced to display a disclaimer, streaming in a loop at the bottom of the screen. The disclaimer would read: “These talking heads have been scientifically proven to not know what they are talking about. Their blather is for entertainment purposes only.” The viewer would then be referred to Tetlock’s most famous research project, which began in 1984.
  • He picked a few hundred political experts – people who made their living “commenting or offering advice on political and economic trends” – and began asking them to make predictions about future events. He had a long list of pertinent questions. Would George Bush be re-elected? Would there be a peaceful end to apartheid in South Africa? Would Quebec secede from Canada? Would the dot-com bubble burst? In each case, the pundits were asked to rate the probability of several possible outcomes. Tetlock then interrogated the pundits about their thought process, so that he could better understand how they made up their minds.
  • Most of Tetlock’s questions had three possible answers; the pundits, on average, selected the right answer less than 33 percent of the time. In other words, a dart-throwing chimp would have beaten the vast majority of professionals. These results are summarized in his excellent Expert Political Judgment.
  • ...5 more annotations...
  • Some experts displayed a top-down style of reasoning: politics as a deductive art. They started with a big-idea premise about human nature, society, or economics and applied it to the specifics of the case. They tended to reach more confident conclusions about the future. And the positions they reached were easier to classify ideologically: that is the Keynesian prediction and that is the free-market fundamentalist prediction and that is the worst-case environmentalist prediction and that is the best case technology-driven growth prediction etc. Other experts displayed a bottom-up style of reasoning: politics as a much messier inductive art. They reached less confident conclusions and they are more likely to draw on a seemingly contradictory mix of ideas in reaching those conclusions (sometimes from the left, sometimes from the right). We called the big-idea experts “hedgehogs” (they know one big thing) and the more eclectic experts “foxes” (they know many, not so big things).
  • The most consistent predictor of consistently more accurate forecasts was “style of reasoning”: experts with the more eclectic, self-critical, and modest cognitive styles tended to outperform the big-idea people (foxes tended to outperform hedgehogs).
  • Lehrer: Can non-experts do anything to encourage a more effective punditocracy?
  • Tetlock: Yes, non-experts can encourage more accountability in the punditocracy. Pundits are remarkably skillful at appearing to go out on a limb in their claims about the future, without actually going out on one. For instance, they often “predict” continued instability and turmoil in the Middle East (predicting the present) but they virtually never get around to telling you exactly what would have to happen to disconfirm their expectations. They are essentially impossible to pin down. If pundits felt that their public credibility hinged on participating in level playing field forecasting exercises in which they must pit their wits against an extremely difficult-to-predict world, I suspect they would be learn, quite quickly, to be more flexible and foxlike in their policy pronouncements.

Why We Already Have False Memories of the COVID-19 Crisis | Psychology Today - 1 views

  • New research sheds light on spotting false memories of emotional events.
  • Have you heard people 'remember' things about the COVID-19 crisis that you know can't be right?
  • Or maybe you have a friend who keeps merging memories of social distancing guidelines?
  • ...19 more annotations...
  • Research has repeatedly shown that false memories can feel incredibly real and can be multi-sensory: In some, we can hear, feel, or see things, just like in real memories. Indeed, to be considered a false memory it can't be a lie, it needs to be part of our reality.
  • I found that if someone has a false memory, we probably can't tell just by looking at the memory. What may be more surprising is that people also seem to be no better than chance at identifying true memories.
  • Source confusion. What we learn from multiple sources about the same topic can very quickly become confused.
  • In both studies, participants were no better than chance at spotting whether a memory was true or false
  • It seems people were actively relying on bad cues when listening to the memories, and somehow these cues made them worse than had they tossed a coin.
  • Participants watched a video of a person recounting a true emotional memory, and the same person recount a false memory. They were told "All, some, or none of the videos you are about to watch involve memories of real accounts. Your task is to identify after each video whether you think the account described actually happened or not.".
  • What this means is that if you already have false memories of what you have done, heard, or seen during the COVID-19 pandemic, you probably can't spot them.
  • This can lead to creating false memories based on source confusion, which is when we misattribute where you learned something.
  • During these unusual times you may want to consider implementing additional safeguards to keep your memories safe.
  • Co-witness contamination. We are all witnesses of this world event, witnesses who are talking to each other all the time. If the COVID-19 pandemic were a crime scene, this would be really bad news.
  • Sameness. Every day we hear unprecedented news or horrific medical stories. But after weeks or months of the same type of information, with a reduction in the amount of new and exciting things happening elsewhere, it gets difficult to separate this long stream of information into meaningful bits.
  • Too late? Already think you or someone else has false memories? Look for independent evidence. You can check the news to see when you actually went into lockdown, or whether you tweeted something about how you felt, or maybe ask a friend what you said to them. That can help establish whether you have a false memory or not.
  • If you want reliable memories of this highly emotional time you need to keep a journal.
  • Assume that those feelings, ideas, fears, beliefs, and experiences will be forgotten. People are generally bad at remembering these details later on.
  • Fake news. Some of the content we see online will be false or misleading.
  • Research has repeatedly shown that false memories can feel incredibly real and can be multi-sensory: In some, we can hear, feel, or see things, just like in real memories.
  • But this week new research takes this even further, and shows that false memories also look real to other people.
  • Both your memory of the news, and your memories of emotional events that are happening in your life are possibly being changed or contaminated.
  • Prevention and evidence are what you need, because it's likely that once you have a false memory, neither you nor anyone else will be able to spot it.

  • What if the scourge of false news on the internet is not the result of Russian operatives or partisan zealots or computer-controlled bots? What if the main problem is us?
  • People are the principal culprits
  • people, the study’s authors also say, prefer false news.
  • ...18 more annotations...
  • As a result, false news travels faster, farther and deeper through the social network than true news.
  • those patterns applied to every subject they studied, not only politics and urban legends, but also business, science and technology.
  • The stories were classified as true or false, using information from six independent fact-checking organizations including Snopes, PolitiFact and FactCheck.org
  • with or without the bots, the results were essentially the same.
  • “It’s not really the robots that are to blame.”
  • “News” and “stories” were defined broadly — as claims of fact — regardless of the source. And the study explicitly avoided the term “fake news,” which, the authors write, has become “irredeemably polarized in our current political and media climate.”
  • False claims were 70 percent more likely than the truth to be shared on Twitter. True stories were rarely retweeted by more than 1,000 people, but the top 1 percent of false stories were routinely shared by 1,000 to 100,000 people. And it took true stories about six times as long as false ones to reach 1,500 people.
  • the researchers enlisted students to annotate as true or false more than 13,000 other stories that circulated on Twitter.
  • “The comprehensiveness is important here, spanning the entire history of Twitter,” said Jon Kleinberg, a computer scientist at Cornell University. “And this study shines a spotlight on the open question of the success of false information online.”
  • The M.I.T. researchers pointed to factors that contribute to the appeal of false news. Applying standard text-analysis tools, they found that false claims were significantly more novel than true ones — maybe not a surprise, since falsehoods are made up.
  • The goal, said Soroush Vosoughi, a postdoctoral researcher at the M.I.T. Media Lab and the lead author, was to find clues about what is “in the nature of humans that makes them like to share false news.”
  • The study analyzed the sentiment expressed by users in replies to claims posted on Twitter. As a measurement tool, the researchers used a system created by Canada’s National Research Council that associates English words with eight emotions
  • False claims elicited replies expressing greater surprise and disgust. True news inspired more anticipation, sadness and joy, depending on the nature of the stories.
  • The M.I.T. researchers said that understanding how false news spreads is a first step toward curbing it. They concluded that human behavior plays a large role in explaining the phenomenon, and mention possible interventions, like better labeling, to alter behavior.
  • For all the concern about false news, there is little certainty about its influence on people’s beliefs and actions. A recent study of the browsing histories of thousands of American adults in the months before the 2016 election found that false news accounted for only a small portion of the total news people consumed.
  • In fall 2016, Mr. Roy, an associate professor at the M.I.T. Media Lab, became a founder and the chairman of Cortico, a nonprofit that is developing tools to measure public conversations online to gauge attributes like shared attention, variety of opinion and receptivity. The idea is that improving the ability to measure such attributes would lead to better decision-making that would counteract misinformation.
  • Mr. Roy acknowledged the challenge in trying to not only alter individual behavior but also in enlisting the support of big internet platforms like Facebook, Google, YouTube and Twitter, and media companies
  • “Polarization,” he said, “has turned out to be a great business model.”

constipation research report intestine

shared by Javier E on 20 Dec 22 - No Cached
  • Slow transit constipation (STC) is a common disease characterized by markedly delayed colonic transit time as a result of colonic motility dysfunction. It is well established that STC is mostly caused by disorders of relevant nerves, especially the enteric nervous system (ENS).
  • After 5 weeks of treatment, CES could enhance the colonic electromyogram (EMG) signal to promote colonic motility, thereby improving the colonic content emptying of STC beagles. HE staining and transmission electron microscopy confirmed that CES could regenerate ganglia and synaptic vesicles in the myenteric plexus.
  • Taken together, pulse train CES could induce the regeneration of myenteric plexus neurons, thereby promoting the colonic motility in STC beagles.

  • onic constipation, a functional bowel disorder, affects approximately 14% of adults worldwide [1]. Slow transit constipation (STC) is the major cause of chronic constipation which is characterized by markedly prolonged colonic transit time as a result of the colonic motility function disorde
  • Usually, patients with STC suffer from a common sense of abdominal pain, nausea, depression and sickness, which seriously influence their social ability and health-related quality of life [4–6
  • Current clinical treatments include cathartics, prokinetics and aggressive surgery which can increase bowel movement frequency to a certain degree.
  • However, pharmacological interventions is prone to drug dependency and relapse after drug withdrawal [3]
  • Surgical treatments such as subtotal colectomy and total colectomy in STC patients may adversely affect the quality of life due to the risk of postoperative diarrhea or incontinence, and result in a heavy healthcare burden
  • The enteric nervous system (ENS), located in the intestinal wall, regulates various functions including contraction of intestine, homeostasis and blood flow [10]. As the ‘second brain’, the ENS contains large amounts of neurons working independently from the central nervous system [11]. Researches have identified that STCs are mostly caused by disorders of the relevant nerves, especially the ENS [12,13].
  • McCallum et al. [35] found that gastric electrical stimulation in combination with pharmacological treatment could also enhance emptying in patients with gastroparesis. Especially, gastric electrical stimulation has been approved as a clinical therapy method for gastroparesis and obesity in European and American countries [36].
  • we employed pulse train stimulation and implanted electrodes at the proximal colon in dogs.
  • After CES treatment, we observed the colonic transit time of the sham treatment group was longer than that of CES treatment and control groups, and electrical stimulation significantly enhanced the colonic electromyogram (EMG) signal.
  • histopathology and TEM analysis showed increased ganglia and synaptic vesicles existing in the colon myenteric plexus of the CES treatment group as compared with that of the sham CES group
  • Our results suggested that CES might reduce the degeneration of the myenteric plexus neurons, thereby contributing to the therapeutic effect on STC beagles.
  • the defecating frequency and the feces characteristics of STC beagles returned to normal after CES treatment. The result indicated that CES could improve the symptoms of STC.
  • The colonic EMG signal was strongly promoted by CES
  • Especially, the colonic EMG signal of the beagles with STC was remarkably enhanced by CES (Figure 3), indicating that CES could not only improve the colonic content emptying, but also enhance the EMG signal to promote colonic motility.
  • Colonic electrical stimulation (CES), a valuable alternative for the treatment of STC, was reported to improve the colon motility by adjusting the bioelectrical activity in animal models or patients with STC [17]. However, little report focuses on the underlying nervous mechanism to normalize the delayed colonic emptying and relieve symptoms. We hypothesized that CES may also repair the disorders of the relevant nerves and then improve the colonic motility.
  • The first study regarding the CES to modulate colonic motility was performed by Hughes et al. [37]. Since then, many researchers employed short-pulse CES in canine descending colon or pig cecum [20,21,38]. Researchers also applied long-pulse CES to stimulate the colon of human or animals [39]
  • Recently, studies showed that the prokinetic effect of pulse train CES is better than that of short-pulse CES or long-pulse CES [25]
  • Our study indicated that CES could enhance the colonic motility, and then accelerate the colonic content emptying. Thereafter, we investigated the underlying mechanism and presumed that CES might improve the STC symptom through the repairment of the ENS.
  • The neuropathy in ENS is considered to be responsible for various kinds of disordered motility including STC and the related pathophysiologic symptoms [40]. In agreement with this view, our study discovered the decreased number of ganglia in the myenteric plexus, as well as the destruction of the enteric nerve axon terminals and synaptic vesicles in the sham CES group beagles
  • The present study proves that CES with pulse trains has curative effects on the colonic motility and content emptying in STC beagles. The up-regulation of intestinal nerve related proteins such as SYP, PGP9.5, CAD and S-100B in the colonic myenteric plexus suggests that CES might reduce the degeneration of the myenteric plexus neurons, thereby producing the therapeutic effect on STC beagles. Further investigation for the underlying mechanism of nerve regeneration is necessary to better understand how CES promotes the recovery of delayed colonic motility induced by STC.

  • How good are people at sifting out fake news?
  • we’ve been investigating whether ordinary individuals who encounter news when it first appears online — before fact-checkers like Snopes and PolitiFacts have an opportunity to issue reports about an article’s veracity — are able to identify whether articles contain true or false information.
  • Unfortunately, it seems quite difficult for people to identify false or misleading news, and the limited number of coronavirus news stories in our collection are no exception
  • ...14 more annotations...
  • Over a 13-week period, our study allowed us to capture people’s assessments of fresh news articles in real time. Each day of the study, we relied on a fixed, pre-registered process to select five popular articles published within the previous 24 hours
  • The five articles were balanced between conservative, liberal and non-partisan sources, as well as from mainstream news websites and from websites known to produce fake news. In total, we sent 150 total articles to 90 survey respondents each
  • We also sent these articles separately to six independent fact checkers, and treated their most common response — true, false/misleading, or cannot determine — for each article as the “correct’’ answer for that article.
  • When shown an article that was rated “true” by the professional fact checkers, respondents correctly identified the article as true 62 percent of the time. When the source of the true news story was a mainstream news source, respondents correctly identified the article as true 73 percent of the time.
  • However, for each article the professional fact checkers rated “false/misleading,” the study participants were as likely to say it was true as they were to say it was false or misleading. And roughly one-third of the time they told us they were unable to determine the veracity of the article. In other words, people on the whole were unable to correctly classify false or misleading news.
  • four of the articles in our study that fact checkers rated as false or misleading were related to the coronavirus.
  • All four articles promoted the unfounded rumor that the virus was intentionally developed in a laboratory. Although accidental releases of pathogens from labs have previously caused significant morbidity and mortality, in the current pandemic multiple pieces of evidence suggest this virus is of natural origin. There’s little evidence that the virus was manufactured or altered.
  • Only 30 percent of participants correctly classified them as false or misleading.
  • respondents seemed to have more trouble deciding what to think about false covid-19 stories, leading to a higher proportion of “could not determine” responses than we saw for the stories on other topics our professional fact checkers rated as “false/misleading.” This finding suggests that it may be particularly difficult to identify misinformation in newly emerging topics
  • Study participants with higher levels of education did better on identifying both fake news overall and coronavirus-related fake news — but were far from being able to correctly weed out misinformation all of the time
  • In fact, no group, regardless of education level, was able to correctly identify the stories that the professional fact checkers had labeled as false or misleading more than 40 percent of the time.
  • Taken together, our findings suggest that there is widespread potential for vulnerability to misinformation when it first appears online. This is especially worrying during the current pandemic
  • In the current environment, misinformation has the potential to undermine social distancing efforts, to lead people to hoard supplies, or to promote the adoption of potentially dangerous fake cures.
  • our findings suggest that non-trivial numbers of people will believe false information to be true when they first encounter it. And it suggests that efforts to remove coronavirus-related misinformation will need to be swift — and implemented early in an article’s life-cycle — to stop the spread of something else that’s dangerous: misinformation.

  • Other researchers reported a consistent association between family dinner frequency and teen academic performance. Adolescents who ate family meals 5 to 7 times a week were twice as likely to get A’s in school as those who ate dinner with their families fewer than two times a week.
  • Children who eat regular family dinners also consume more fruits, vegetables, vitamins and micronutrients, as well as fewer fried foods and soft drinks.
  • And the nutritional benefits keep paying dividends even after kids grow up: young adults who ate regular family meals as teens are less likely to be obese and more likely to eat healthily once they live on their own.
  • Some research has even found a connection between regular family dinners and the reduction of symptoms in medical disorders, such as asthma.
  • The benefit might be due to two possible byproducts of a shared family meal: lower anxiety and the chance to check in about a child’s medication compliance.
  • The dinner atmosphere is also important. Parents need to be warm and engaged, rather than controlling and restrictive, to encourage healthy eating in their children.
  • In a very recent study, kids who had been victims of cyberbullying bounced back more readily if they had regular family dinners.
  • Family dinners have been found to be a more powerful deterrent against high-risk teen behaviors than church attendance or good grades.
  • In a New Zealand study, a higher frequency of family meals was strongly associated with positive moods in adolescents. Similarly, other researchers have shown that teens who dine regularly with their families also have a more positive view of the future, compared to their peers who don’t eat with parents.

  • Of course, the real power of dinners lies in their interpersonal quality. If family members sit in stony silence, if parents yell at each other, or scold their kids, family dinner won’t confer positive benefits.

  • In other words, this fallacy assumes that whatever it takes to make a premise true is already there, even if it is really absent or unknown.
  • This common fallacy of the false assumption often overlaps with a number of other logical fallacies in subtle ways, and thus it is not always obvious and can be difficult to spot. In fact, some logic texts consider false or unwarranted assumptions as an inherent characteristic of a whole host of other logical fallacies.¹ However there are characteristics of this fallacy which make it stand out—specifically the reliance of a premise on prior unsupported or unstated assumptions that turn out to be false

testing mass statistics innumeracy numeracy probability probabilistic thinking

shared by Javier E on 31 Aug 20 - No Cached
  • Short of a vaccine, mass testing is among the most plausible paths back to some kind of normalcy.
  • Imagine a world where you could stop at a drive-through testing center, get a result in 20 minutes or so, and then motor onward to your dinner party with a “negative” certificate in hand. Imagine outdoor kiosks at airports, with a negative test result required to get inside. Imagine offices, even restaurants or bars, with a nurse stationed in the parking lot.
  • Would this be annoying and cumbersome? Yes. Would it be a vast improvement on what we are doing now? Also yes. It even seems plausible since Abbott Labs has won emergency approval for a test that costs $5, returns an answer in 15 minutes, requires no specialized equipment and can be produced in bulk. Mass deployment of this test, or others like it, could fundamentally change how we approach covid-19.
  • ...10 more annotations...
  • No test is perfectly accurate; all generate false positives and false negatives. How many varies by the test — the new Abbott Labs test, for example, has a false negative rate of about 3 percent and a false positive rate of about 1.5 percent.
  • We’d also require public understanding that test results are a risk-assessment tool rather than a definitive answer. And shifting the public’s thinking might be harder than shifting Trump.
  • Doing that would also require fundamentally changing our thinking.
  • For mass testing to work, people will need to understand that even an event where all attendees just tested negative isn’t necessarily covid-free, because some false negatives might have slipped through
  • Giving hundreds of millions of citizens this crash course in elementary statistics would be very difficult. Teaching people how to think about a positive result would be even harder — especially if mass testing does its job of reducing caseloads. Because as case numbers fall, false positives will become a bigger and bigger problem.
  • Say we’re testing 200 people, 10 of whom have covid-19. Given its rate of false negatives, the Abbott test would probably catch all 10. But with false positives, it could also tell one or two people who don’t have covid-19 that they’re infected. That’s not ideal — as good citizens, they’d have to go home and quarantine. But a more sensitive follow-up test could substantially mitigate this problem, shortening such quarantines to a day or so. It would be worth it to get those 10 true positives out of circulation.
  • Doing this, we might eventually reduce the share of the population that’s infected to, say, 0.5 percent from 5 percent. Unfortunately, the false positive rate won’t budge, so now for every one true positive uncovered, roughly three false positives would still be generated.
  • That’s inherently costly: Every false positive means skipping your flight, rehearsal or birthday party. But it would be catastrophic if people didn’t understand that a positive covid-19 test is a guideline, not a guarantee
  • People who think that they’ve had covid-19, when they haven’t, are apt to go out and engage in risky behavior, maybe a lot of it. And if mass testing ever becomes common, there could be a lot of those people.
  • So mass testing isn’t just a matter of getting a test that is cheap enough and plentiful enough; the administration and the public must be educated to use this bounty wisely. That’s a hard messaging problem. Given the alternative, though, it’s the kind of problem we’d really like to have.

Phantom limb pain: A literature review - 0 views

www.ncbi.nlm.nih.gov/...PMC6354174

shared by katedriscoll on 03 Nov 20 - No Cached
  • . The purpose of this review article is to summarize recent researches focusing on phantom limb in order to discuss its definition, mechanisms, and treatments.
  • The incidence of phantom limb pain has varied from 2% in earlier records to higher rates today. Initially, patients were less likely to mention pain symptoms than today which is a potential explanation for the discrepancy in incidence rates. However, Sherman et al.4 discuss that only 17% phantom limb complaints were initiated treated by physicians. Consequently, it is important to determine what constitutes phantom pain in order to provide efficacious care. Phantom pain is pain sensation to a limb, organ or other tissue after amputation and/or nerve injury.5 In podiatry, the predominant cause of phantom limb pain is after limb amputation due to diseased state presenting with an unsalvageable limb. Postoperative pain sensations from stump neuroma pain, prosthesis, fibrosis, and residual local tissue inflammation can be similar to phantom limb pain (PLP). Patients with PLP complain of various sensations including burning, stinging, aching, and piercing pain with changing warmth and cold sensation to the amputated area which waxes and wanes.6 Onset of symptoms may be elicited by environmental, emotional, or physical changes.
  • The human body encompasses various neurologic mechanisms allowing reception, transport, recognition, and response to numerous stimuli. Pain, temperature, crude touch, and pressure sensory information are carried to the central nervous system via the anterolateral system, with pain & temperature information transfer via lateral spinothalamic tracts to the parietal lobe. In detail, pain sensation from the lower extremity is transported from a peripheral receptor to a first degree pseudounipolar neurons in the dorsal root ganglion and decussate and ascend to the third-degree neurons within the thalamus.7 This sensory information will finally arrive at the primary sensory cortex in the postcentral gyrus of the parietal lobe which houses the sensory homunculus.8 It is unsurprising that with an amputation that such an intricate highway of information transport to and from the periphery may have the potential for problematic neurologic developments.

  • How does pain sensation, a protection mechanism for the human body, become chronic and unrelenting after limb loss? This is a question researchers still ask today with no concise conclusion. Phantom limb pain occurs more frequently in patients who also experience longer periods of stump pain and is more likely to subside as the stump pain subsides.9 Researchers have also found dorsal root ganglion cells change after a nerve is completely cut. The dorsal root ganglion cells become more active and sensitive to chemical and mechanical changes with potential for plasticity development at the dorsal horn and other areas.10 At the molecular level, increasing glutamate and NMDA (N-methyl d-aspartate) concentrations correlate to increased sensitivity which contributes to allodynia and hyperalgesia.11 Flor et al.12 further described the significance of maladaptive plasticity and the development of memory for pain and phantom limb pain. They correlated it to the loss of GABAergic inhibition and the development of glutamate induced long-term potentiation changes and structural changes like myelination and axonal sprouting.
  • Phantom limb pain in some patients may gradually disappear over the course of a few months to one year if not treated, but some patients suffer from phantom limb pain for decades. Treatments include pharmacotherapy, adjuvant therapy, and surgical intervention. There are a variety of medications to choose from, which includes tricyclic antidepressants, opioids, and NSAIDs, etc. Among these medications, Tricyclic antidepressant is one of the most common treatments. Studies have shown that Amitriptyline (a tricyclic antidepressant) has a good effect on relieving neuropathic pain.25
  • Phantom limb pain is very common in amputees. As a worldwide issue, it has been studied by a lot of researchers. Although phantom limb sensation has already been described and proposed by French military surgeon Ambroise Pare 500 years ago, there is still no detailed explanation of its mechanisms. Therefore, more research will be needed on the different types of mechanisms of phantom limb pain. Once researchers and physicians are able to identify the mechanism of phantom limb pain, mechanism-based treatment will be rapidly developed. As a result, more patients will be benefit from it in the long run.

  • psychologist Elizabeth Loftus of the University of California–Irvine, has made her name working on false memory. She tells Alison George how recollections can be conjured up,
  • Is it the power of suggestion from a therapist that creates these "memories," then? EL: Yes, a lot of the cases involve suggestive psychotherapy. But you don't absolutely need the therapy. You can get suggestion from the culture and the environment, like when somebody turns on Oprah and sees one of these repressed-memory therapists talking, then believes this has happened to them.
  • The memory of witnesses to crimes and accidents was a natural place to go. In particular I looked at what happens when people are questioned about their experiences. I would ultimately see those questions as a means by which the memories got contaminated.
  • ...5 more annotations...
  • Depending on the study, you might get as many as 50 percent of people falling for the suggestion and developing a complete or partial false memory.
  • What exactly is going on when we retrieve a memory? EL: When we remember something, we're taking bits and pieces of experience—sometimes from different times and places—and bringing it all together to construct what might feel like a recollection but is actually a construction. The process of calling it into conscious awareness can change it, and now you're storing something that's different
  • How do you plant these memories? EL: We use a "false feedback" technique. We gather a whole bunch of data from you, about your personality, thoughts about different foods, all kinds of things. Later, we hand you this computerized profile, which reveals certain things that probably happened when you were a child. In the middle of the list is, say, that you got sick eating strawberry ice cream. We give you false feedback about your data, and then encourage you to elaborate and imagine. Later we ascertain whether you have a belief that it happened to you. Then we offer you a choice from all these different foods. In that example we found that participants didn't want strawberry ice cream as much.
  • bad governments, bad people, they don't have requirements of conduct. When we recently published a study about planting false memories among U.S. soldiers, I was worried we were putting out a recipe for how you can do horrible things to somebody and then wipe their memory away.
  • Is there any way to distinguish a false memory from a real one? EL: Without independent corroboration, little can be done to tell a false memory from a true one.

  • The moments we remember from the first years of our lives are often our most treasured because we have carried them longest. The chances are, they are also completely made up.
  • Around four out of every 10 of us have fabricated our first memory, according to researchers. This is thought to be because our brains do not develop the ability to store autobiographical memories at least until we reach two years old.
  • Yet a surprising number of us have some flicker of memory from before that age
  • ...23 more annotations...
  • Experts have managed to turn people off all sorts of foods by convincing them it had made them ill when they were a child
  • “People have a life story, particularly as they get older and for some people it needs to stretch back to the very early stage of life,”
  • The prevailing account of how we come to believe and remember things is based around the concept of source monitoring. “Every time a thought comes to mind we have to make a decision – have we experienced it [an event], imagined it or have we talked about it with other people,” says Kimberley Wade
  • Most of the time we make that decision correctly and can identify where these mental experiences come from, but sometimes we get it wrong.
  • Wade admits she has spent a lot of time recalling an event that was actually something her brother experienced rather than herself, but despite this, it is rich in detail and provokes emotion
  • Memory researchers have shown it is possible to induce fictional autobiographical memories in volunteers, including accounts of getting lost in a shopping mall and even having tea with a member of the Royal Family
  • Based on my research, everybody is capable of forming complex false memories, given the right circumstances – Julia Shaw
  • In some situations, such as after looking at pictures or a video, children are more susceptible to forming false memories than adults. People with certain personality types are also thought to be more prone.
  • But carrying around false memories from your childhood could be having a far greater impact on you than you may realise too. The events, emotions and experiences we remember from our early years can help to shape who we are as adults, determining our likes, dislikes, fears and even our behaviour.
  • Memories before the age of three are more than likely to be false. Any that appear very fluid and detailed, as if you were playing back a home video and experiencing a chronological account of a memory, could well also be made up. It is more likely that fuzzy fragments, or snapshots of moments are real, as long as they are not from too early in your life.
  • We crave a cohesive narrative of our own existence and will even invent stories to give us a more complete picture
  • Interestingly, scientists have also found positive suggestions, such as “you loved asparagus the first time you ate it” tend to be more effective than negative suggestions like “you got sick drinking vodka”
  • “Miscarriage of justice, incarceration, loss of reputation, job and status, and family breakdown occur,
  • One of the major problems with legal cases involving false memories, is that it is currently impossible to distinguish between true and fictional recollections
  • Efforts have been made to analyse minor false memories in a brain scanner (fMRI) and detect different neurological patterns, but there is nothing as yet to indicate that this technology can be used to detect whether recollections have become distorted.
  • the most extreme case of memory implantation involves a controversial technique called “regression therapy”, where patients confront childhood traumas, supposedly buried in their subconscious
  • “Memories are malleable and tend to change slightly each time we revisit them, in the same way that spoken stories do,”
  • “Therefore at each recollection, new elements can easily be integrated while existing elements can be altered or lost.”
  • This is not to say that all evidence that relies on memory should be discarded or regarded as unreliable – they often provide the most compelling testimony in criminal cases. But it has led to rules and guidelines about how witnesses and victims should be questioned to ensure their recollections of an event or perpetrator are not contaminated by investigators or prosecutors.
  • Any memories that appear very fluid and detailed, as if you were playing back a home video, could well also be made up
  • While this may seem like a bit of fun, many scientists believe the “false memory diet” could be used to tackle obesity and encourage people to reach for healthier options like asparagus, or even help cut people’s alcohol consumption.
  • Children are more susceptible to forming false memories than adults, especially after looking at photographs or films
  • And we may not want to rid ourselves of these memories. Our memories, whether fictional or not, can help to bring us closer together.

    As we learned in TOK, science is full of uncertainties. And in this article, the author suggests that even the publication of science paper is full of flaws. But the general population often cited science source that's in support of them. However, science findings are full of faults and the possibility is very high for the scientists to make a false claim. Sometimes, not the errors in experiments, but the fabrication of data lead to false scientific papers. And also, there are a lot of patterns behind the publication of false scientific papers.

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.

  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

  • “We think parts of the brain used to actually perceive an object and to imagine an object overlap,” says Northwestern University scientist Kenneth Paller. “Thus, the vividly imagined event can leave a memory trace in the brain that’s very similar to that of an experienced event.”
  • How this process works is a research question of great interest to neuroscientists. This week, researchers affiliated with a project at MIT reported a giant step toward explaining how external stimuli can distort mental representations to produce brand new, seemingly accurate—but completely false—memories.

  • A member of the MIT team, Susumu Tonegawa, commented on the significance of the research in Science  magazine's weekly podcast:Independent of what is happening around you in the outside world, humans constantly have internal activity in the brain. So just like our mouse, it is quite possible we can associate what we happen to have in our mind with a bad or good high valence, online event. So, in other words, there could be a false association of what you have in your mind rather than what is happening to you, so this is a way we believe that at least some form of strong force memory observed in humans could be made. Because our study showed that the false memories and the genuine memories are based on very similar, almost identical, brain mechanisms, it is difficult for the false memory bearer to distinguish between them. So we can study this, because we have a mouse model now.

It's Time for a Real Code of Ethics in Teaching - Noah Berlatsky - The Atlantic - 3 views

ethics teaching cheating analysis education

shared by Javier E on 07 Apr 13 - No Cached
  • More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.
  • Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"
  • Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.
  • ...8 more annotations...
  • Behaving ethically matters, but how it matters, and what it means, depends strongly on the context in which it occurs.
  • Ethics for teachers is not, apparently, first and foremost about educating their students, or broadening their minds. Rather, ethics for teachers in our current system consists in following the rules. The implicit, linguistic signal being given is that teachers are not like journalists or doctors, committed to a profession and to the moral code needed to achieve their professional goals. Instead, they are like athletes playing games, or (as Chait says) like children taking tests.
  • Using "cheating" as an ethical lens tends to both trivialize and infantilize teacher's work
  • Professions with social respect and social capital, like doctors and lawyers, collaborate in the creation of their own standards. The assumption is that those standards are intrinsic to the profession's goals, and that, therefore, professionals themselves are best equipped to establish and monitor them. Teachers' standards, though, are imposed from outside -- as if teachers are children, or as if teaching is a game.
  • High-stakes testing, then, does leads to cheating. It does not create unethical behavior -- but it does create the particular unethical behavior of "cheating."
  • We have reached a point where we can only talk about the ethics of the profession in terms of cheating or not cheating, as if teachers' main ethical duty is to make sure that scantron bubbles get filled in correctly. Teachers, like journalists, should have a commitment to truth; like doctors, they have a duty of care. Translating those commitments and duties into a bureaucratized measure of cheating-or-not-cheating diminishes ethic
  • For teachers it is, literally, demoralizing. It severs the moral experience of teaching from the moral evaluation of teaching, which makes it almost impossible for good teachers (in all the senses of "good") to stay in the system.
  • We need better ethics for teachers -- ethics that treat them as adults and professionals, not like children playing games.
