The Shanghai Secret - NYTimes.com - 26 views

  •  
    HANGHAI - Whenever I visit China, I am struck by the sharply divergent predictions of its future one hears. Lately, a number of global investors have been "shorting" China, betting that someday soon its powerful economic engine will sputter, as the real estate boom here turns to a bust. Frankly, if I were shorting China today, it would not be because of the real estate bubble, but because of the pollution bubble that is increasingly enveloping some of its biggest cities. Optimists take another view: that, buckle in, China is just getting started, and that what we're now about to see is the payoff from China's 30 years of investment in infrastructure and education. I'm not a gambler, so I'll just watch this from the sidelines. But if you're looking for evidence as to why the optimistic bet isn't totally crazy, you might want to visit a Shanghai elementary school.

Memory - Wikipedia, the free encyclopedia - 0 views

  • Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).
  • Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).
  • Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

  • Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
  • At the Center for Cognitive Science at Ohio State University, researchers have found that memory accuracy of adults is hurt by the fact that they know more, and have more experience than children, and tend to apply all this knowledge when learning new information. The findings appeared in the August 2004 edition of the journal Psychological Science.
  • Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information[59] and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French – this phenomenon is known as positive transfer.[60]
  • Methods to optimize memorization[edit] Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming which is intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.[72]

picturing the thirties - 2 views

  •  
    "Picturing the 1930s," a new educational web site created by the Smithsonian American Art Museum in collaboration with the University of Virginia, allows teachers and students to explore the 1930s through paintings, artist memorabilia, historical documents, newsreels, period photographs, music, and video. Using PrimaryAccess, a web-based teaching tool developed at the university's Curry Center for Technology and Teacher Education, visitors can select images, write text, and record narration in the style of a documentary filmmaker. They can then screen their video in a virtual theater. PrimaryAccess is the first online tool that allows students to combine their own text, historical images from primary sources, and audio narration to create short online documentary films linked to social studies standards of learning, said Glen Bull, co-director of the Curry Center. Since the first version was developed in collaboration with U.Va.'s Center for Digital History and piloted in a local elementary school in 2005, more than 9,000 users worldwide have created more than 20,000 short movies. In creating digital documentaries, students embed facts and events in a narrative context that can enhance their retention and understanding of the material, said Curry research scientist Bill Ferster, who developed the application with Bull. Besides increasing their knowledge about the period, "Picturing the 1930s" enhances students' visual literacy skills, Ferster noted, adding that PrimaryAccess "offers teachers another tool to bring history alive."

How Teens Do Research in the Digital World | Pew Research Center's Internet & American ... - 105 views

  • Overview Three-quarters of AP and NWP teachers say that the internet  and digital search tools have had a “mostly positive” impact on their students’ research habits, but 87% say these technologies are creating an “easily distracted generation with short attention spans” and 64% say today’s digital technologies “do more to distract students than to help them academically.”
  • Overall, the vast majority of these teachers say a top priority in today’s classrooms should be teaching students how to “judge the quality of online information.”
  • The internet and digital technologies are significantly impacting how students conduct research: 77% of these teachers say the overall impact is “mostly positive,” but they sound many cautionary notes
  • ...9 more annotations...
  • Teachers and students alike report that for today’s students, “research” means “Googling.”  As a result, some teachers report that for their students “doing research” has shifted from a relatively slow process of intellectual curiosity and discovery to a fast-paced, short-term exercise aimed at locating just enough information to complete an assignment.
    • Kelly Sereno
       
      Yikes - a disturbing survey response!
  •   Second and third on the list of frequently used sources are online encyclopedias such as Wikipedia, and social media sites such as YouTube. 
  •  94% of the teachers surveyed say their students are “very likely” to use Google or other online search engines in a typical research assignment, placing it well ahead of all other sources that we asked about
  • e databases such as EBSCO, JSTOR, or Grolier (17%) A research librarian at their school or public library (16%)
  • In response to this trend, many teachers say they shape research assignments to address what they feel can be their students’ overdependence on search engines and online encyclopedias.  Nine in ten (90%) direct their students to specific online resources they feel are most appropriate for a particular assignment, and 83% develop research questions or assignments that require students to use a wider variety of sources, both online and offline.
  • Teachers give students’ research skills modest ratings Despite viewing the overall impact of today’s digital environment on students’ research habits as “mostly positive,” teachers rate the actual research skills of their students as “good” or “fair” in most cases.  Very few teachers rate their students “excellent” on any of the research skills included in the survey.  This is notable, given that the majority of the sample teaches Advanced Placement courses to the most academically advanced students.
    • Kelly Sereno
       
      These research skills relate to the common core literacy standards, and many ratings of students' skills in these areas fell into fair or poor categories.
  • Overwhelming majorities of these teachers also agree with the assertions that “today’s digital technologies are creating an easily distracted generation with short attention spans” (87%) and “today’s students are too ‘plugged in’ and need more time away from their digital technologies” (86%).  Two-thirds (64%) agree with the notion that “today’s digital technologies do more to distract students than to help them academically.”

The Not-So-Hidden Cause Behind the A.D.H.D. Epidemic - NYTimes.com - 58 views

    Between the fall of 2011 and the spring of 2012, people across the United States suddenly found themselves unable to get their hands on A.D.H.D. medication. Low-dose generics were particularly in short supply. There were several factors contributing to the shortage, but the main cause was that supply was suddenly being outpaced by demand.

  • we expected that they would display a predominance of those forms of thought that come from activity that is guided by the physical features of familiar objects.
  • Therefore we began, as most field work with people does, by emphasizing contact with the people who would serve as our subjects. We tried to establish friendly relations so that experimental sessions seemed natural and non-threatening. We were particularly careful not to conduct hasty or unprepared presentations of the test materials.
  • As a rule, our experimental sessions began with long conversations which were sometimes repeated with the subjects in the relaxed atmosphere of a tea house, where the villagers spent most of their free time, or in camps in the field and in mountain pastures around the evening campfire. These talks were frequently held in groups. Even when the interviews were held with one person, the experimenter and other subjects made up a group of two or three who listened attentively to the person being interviewed and who sometimes offered remarks or comments on what he said. The talk often took the form of a free-flowing exchange of opinion between participants, and a particular problem might be solved simultaneously by two or three subjects, each proposing an answer. Only gradually did the experimenters introduce the prepared tasks, which resembled the “riddles” familiar to the population and therefore seemed like a natural extension of the conversation.
  • He characterized primitive thinking as “prelogical” and “loosely organized.” Primitive people were said to be indifferent to logical contradiction and dominated by the idea that mystical forces control natural phenomena

  • 1. Women living in remote villages who were illiterate and who were not involved in any modern social activities. There were still a considerable number of such women at the time our study was made. Their interviews were conducted by women, since they alone had the right to enter the women's quarters. 2. Peasants living in remote villages who were in no way involved with socialized labor and who continued to maintain an individualistic economy. These peasants were not literate. 3. Women who attended short-term courses in the teaching of kindergarteners. As a rule, they had no formal schooling and almost no training in literacy. 4. Active kolhoz (collective farm) workers and young people who had taken short courses. They were involved as chairmen running collective farms, as holders of other offices on the, collective farm, or as brigade leaders. They had considerable experience in planning production, distributing labor, and taking stock of output. By dealing with other collective farm members, they had acquired a much broader outlook than isolated peasants. But they had attended school only briefly, and many were still barely literate. 5. Women students admitted to teachers school after two or three years of study. Their educational qualifications, however, were still fairly low.

Looking in the Wrong Places | Edge.org - 5 views

  • We should be very careful in thinking about whether we’re working on the right problems. If we don’t, that ties into the problem that we don’t have experimental evidence that could move us forward. We're trying to develop theories that we use to find out which are good experiments to make, and these are the experiments that we build.   We build particle detectors and try to find dark matter; we build larger colliders in the hope of producing new particles; we shoot satellites into orbit and try to look back into the early universe, and we do that because we hope there’s something new to find there. We think there is because we have some idea from the theories that we’ve been working on that this would be something good to probe. If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • I’m still asking myself the same question that I asked myself ten years ago: "What is going on in my community?" I work in the foundations of physics, and I see a lot of strange things happening there. When I look at the papers that are being published, many of them seem to be produced simply because papers have to be produced. They don’t move us forward in any significant way. I get the impression that people are working on them not so much because it’s what they’re interested in but because they have to produce outcomes in a short amount of time. They sit on short-term positions and have short-term contracts, and papers must be produced.
  • The field that I mostly work in is the foundations of physics, which is, roughly speaking, composed of cosmology, the foundations of quantum mechanics, high-energy particle physics, and quantum gravity. It’s a peculiar field because there hasn’t been new data for almost four decades, since we established the Standard Model of particle physics. There has been, of course, the Higgs particle that was discovered at the LHC in 2012, and there have been some additions to the Standard Model, but there has not been a great new paradigm change, as Kuhn would have put it. We’re still using the same techniques, and we’re still working with the same theories as we did in the 1970s.
  • ...10 more annotations...
  • That makes this field of science rather peculiar and probably explains why there hasn’t been much progress. But it’s not like we don’t have any questions that need to be answered. There are a lot of questions that have been around for decades. For example, what is dark energy? What is dark matter? What are the masses of the Standard Model particles? And what’s up with the foundation of quantum mechanics? Is a theory that's fundamentally not deterministic, where we cannot predict outcomes, the last word that we have, or is there something more to it? Is there maybe another underlying structure to reality?
  • but we haven't reached the fundamental level. Maybe we will never reach it. Certainly, the theories that we have right now are not all there is. The question is, of course, if we don’t have any guidance by experiment, how do we make progress? And are we doing the right thing?
  • We’ve reached this point where we have to carefully rethink if the criteria that we’re using to select our theories are promising at all. If one looks at the history of this field in the foundations of physics, progress has usually been made by looking at questions that, at least in hindsight, were well posed, where there was an actual mathematical contradiction. For example, special relativity is incompatible with Newtonian gravity. If you try to resolve this incompatibility, you get general relativity.
  • There are various similar examples where such breakthroughs have happened because there was a real problem. There was an inconsistency and people had to resolve it. It had nothing to do with beauty. Maybe beauty was, in some cases, the personal motivation of the people to work on it. There’s certainly some truth to this, but I don’t think it’s good to turn this story around and say that if we only pay attention to this motivation that comes from ideals of beauty it will lead to progress.
  • If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • The way that research is funded in foundations of physics and in many other fields just puts a lot of things at a disadvantage that are not pursued anymore. Typically, everything that takes longer than three years to complete, no one will start it because they can’t afford it. They can literally not afford it.
  • Who makes the decisions about the funding? Superficially, people say that it's a funding agency, so it’s the university who get to hire people. But that puts the blame on the wrong party. In the end it’s the community itself who makes the decisions. What do the funding agencies do if they get a proposal? They send it to reviewers. And who are the reviewers? They're people from the same community. If you look at how hiring decisions are being made, there’s some committee and they are people from the same community. They have some advisory boards or something, which contains people from the same community.
  • Even if that wasn’t so, what the people in these committees would be doing is looking at easy measures for scientific success. Presently, the most popular of these measures are the number of publications and the number of citations. And maybe also whether the person has published in high-impact journals. So, these are the typical measures that are presently being used. But what do they measure? They primarily measure popularity. They indicate whether somebody’s research is well received by a lot of people in the same community. And that’s why once a research area grows beyond a certain critical mass, you have sufficiently many people who tell each other that what they’re doing is the good thing to do. They review each other’s papers and say that that’s great and it's what we should continue to do. It’s a problem in all communities that grow beyond a certain size.
  • I later came to the United States and then Canada, and that gave me the opportunity to learn a lot about quantum gravity. I also figured out that much of what goes on in quantum gravity is very detached from reality. It’s pretty much only mathematics. Yes, the mathematics is there, but I still don’t know if it’s the mathematics that describes reality.
  • That’s the very reason why we don’t normally think of gravity as a weak force. It’s the only force that is left over on long distances, and the reason for this is that it adds up. It gets stronger the more mass you pile up. More precisely, we should say that the reason we find it so hard to measure quantum gravitational effects is that we either have a particle that has very pronounced quantum properties, like, say, a single electron or something like that, but then it’s so light that we cannot measure the gravitational field. Or we have some object that is so heavy that we can measure the gravitational field, but then it doesn’t have quantum properties. Okay, so that’s the actual problem.
