  • A Juicy Word is a word that has some real substance to it. Juicy Words are special, more so than your everyday, dried-out variety of words.
  • First, I ask students to collect ten Juicy Words per week
  • from text or from speech
  • ...4 more annotations...
  • note about where they found the word and how it was used
  • uring Week 2, I ask students to continue collecting ten Juicy Words per week, and in addition, to identify their three favorite Juicy Words and to use them at some point
  • In their Week 2 posts, students share their three Juicy Words, information about where they sourced each word, a brief explanation of each word's meaning, and how they used each word in real life.
  • By Week 5, the students are using five of their Juicy Words per week, and collecting an average of 15—five more than the ten words that I require

shared by Kate Pok on 24 Nov 11 - Cached
  • Always convert all grades and numbers to a system of 100. It will not only be easier for you to figure out overall grades, but it will simplify your explanations to parents and administrators if they can see your grades in terms of percents.
  • FAILING GRADES BELOW "50" ALWAYS GET MARKED AS A SCORE OF "50"
  • All letter grades are converted to a numerical equivalent, equi-spaced from each other, based on a 100 point system. Then they are averaged as you would with other grades. Here is a chart you can use: A++ = 100 (perfect paper with extra-credit) A+ = 98 A = 95 A- = 92 B+ = 88 B = 85 B- = 82 C+ = 78 C = 75 C- = 72 D+ = 68 D = 65 D- = 62 F = 55

  • EXAMPLE: The student in the example received: 25, 80, 40, 95, 90. Average = 66%, Grade = D The student's grades should be converted to 50 , 80, 50 , 95, 90. Average = 73%, Grade = C, which is a better representation of grades of A, A-, B-, F, F.

      What do you think the author means in the highlighted text "but how we view something of the past is largely due to our own past and present experiences"?
  • ...10 more annotations...
  • Secondly, but along the same lines as the above explanation, is that the people writing history change as well
  • The social changes of the 1960s and 1970s brought many women historians into what had largely been a male dominated field and introduced new perspectives and told new stories that had previously been undiscovered (unfortunately, due to lack a of male interest) or ignored (unfortunately, due to a lack of male interest).
    • Julie Sully
      Julie Sully on 25 Nov 14
       
      What new perspective could women bring to the study of history? Why would it be different then a mans perspective?
  • History was once written largely only through limited primary sources; letters, journals, diaries, and newspapers, and of course, secondary sources-what others had already written. But historians not so long ago began to "think outside the box," and by using sources such as estate
  • inventories, court documents, and even oral histories, these historians opened up a world of new information.
  • Locating new information of course changed how we saw events of the past, and only naturally new interpretations developed...and in this way one could say history changed.
    • Julie Sully
      Julie Sully on 25 Nov 14
       
      How would new information change history? 
  • Lastly, and related to the third, is that the availability of research sources have changed...largely through technology
  • All of this makes researching much easier and much less frustrating for the historian, and it allows him or her more time to make critical decisions, and to explore avenues that would not otherwise be considered.

      Why would having access to all of these resources benefit historians?

Psilocybin (magic mushrooms) - 0 views

shared by Kenuvis Romero on 23 Jun 13 - No Cached
  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • 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
  • ...15 more annotations...
  • 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
  • traces of the compund can be detected in unine even after 7 days.
  • 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.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • 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
    • Kenuvis Romero
      Kenuvis Romero on 23 Jun 13
       
      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • 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

    More and more people are throwing away their USB memory sticks (but probably just losing them down the back of the sofa) in favour of cloud storage. This is a wonderful storage site, download and multi-platform app which is very similar to Dropbox. A synced folder sits on you devices and can be updated and accessed from any device. You can generating a url to share folders or files with other people. It works just fine on a computer with Dropbox already installed and the free account gives you 15GB of storage. That's enough storage where 'tidy' filing schools might begin to migrate their school network storage to the cloud for free - and that's exciting. Additional storage is available for a price.

      Great way to provide equitable access opportunities
  • Teachers need to figure out what they want to get out of a flipped classroom, says Marine City High’s Ming. “What’s the purpose of doing it? Is it because you’re looking for more time in your curriculum to do hands-on activities?” An AP government teacher told Ming the best part of teaching his class was holding class discussions. The flipped classroom helped him get through the material with time to spare for conversation.

      The purpose is always the key. Don't try to implement this "just because" or excessively. It is a great tool, but not always the right one.
  • Watching videos also means more sitting in front of devices. The American Academy of Pediatrics recommends kids limit “screen time” to two hours a day because too much exposure has been linked to obesity, irregular sleep, behavioral problems, violence, and less time for play.

      Why not flip it with podcasts that students can listen to while walking, driving, etc.
  • Students need to feel as though their teachers are guiding them to the best materials, not merely giving them a list of videos to watch, says Valenza
  • “Teachers should keep posing the ‘why,’” says Bob Schuetz, the technology director at Palatine High School in Illinois. “Why am I doing this? Why is it beneficial to students?”
  • “The teacher walks around and helps everyone. It’s not a get-out-of-jail-free card for teachers not to teach.” It’s also not a way for kids to get out of doing anything at home. “Flipping what the kid does means they do the work ahead of time, come to class, and debrief,” explains Michelle Luhtala (aka the
  • “The end goal is personalized education. The flipped classroom is just a means to that end.” Students can use the videos to learn at their own pace—any time or place, says Roberts. “These students can replay their teacher’s explanation of a new concept as many times as they need to without fear of holding up the rest of the class.”
  • a librarian at Bullis School in Potomac, MD, gives students videos, Web pages, and screenshots about the nuts and bolts of the library, which frees up more time to devote to their research projects.
  • ure, some kids will ignore the video. “The same kids who don’t currently do their homework will not watch the lecture,” says McCammon. “But as you start making your class more engaging, kids who don’t usually do their homework will start doing it because they want to participate in the class.” Kids write questions down while they’re watching the video, and then the first 10 minutes of class is for discussion of what they’ve seen.

  • he researchers report their findings in the advance online publication of the Nature Cell Biology July issue. The cells in our bodies constantly sense their environment and respond appropriately. For example, if pathogens invade the body, cells will respond by generating an inflammatory environment to fight the pathogen. This is achieved by intricate molecular circuits within cells that sense and relay external signals and orchestrate the cellular response. Aberrant functioning of these cellular switch boards can lead to diseases including autoimmune disorders and cancer. In the study, an the scientists set out to better understand the molecular workings underlying inflammation. Inflammation, the body's primary line of defense against disease-causing microbes and parasites, is a highly complex and tightly regulated biochemical process involving a myriad of specialized cells communicating with each other through an arsenal of signaling molecules.

shared by Dallas McPheeters on 28 Jul 10 - Cached
  • Here’s how it works, step by step: The transmitter chip is made of four hybrid silicon lasers. Light beams from the lasers each travel into an optical modulator. The modulator encodes data onto the beams at 12.5Gbps. The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors. The photo detectors convert data back into electrical signals.

diigo education review

shared by kathy dounelis on 13 Jan 09 - Cached
  • I tried out Diigo educator and was REALLY impressed. This let me very quickly (and with no email addresses needed) set up accounts for 30 students. I then created a group for all 3 classes to use and added all the students to the group. In this case, since I only have one more day with the kids and am not sure if they'll be using Diigo after this, I just used the 30 accounts for multiple classes, but if this were for my actual students, I would have created an account for each student. Anyway, once all the students were added to the group, I just instructed them to make sure to share every bookmark for this project with the group. All of the students will then be able to view all of the bookmarks. Again, we couldn't install even the diigolet, but saving right from Diigo worked fine for our purposes. They used the same technique of tagging with last name, class hour, and other appropriate tags. I taught both of these methods in a 45 minute class period and the actual explanation of the bookmarking technique took only 7-10 min. of each class period. The kids (7th graders) picked up on it EXTREMELY fast.
  • for long term use and for individual projects I strongly recommend using Diigo educator, especially since I use Diigo so heavily in my personal and professional web research.

  • Certainly there is the entertainment element to this service, however I also see a great deal of potential for educational value as well. The Common Craft Show has shown us that hand-drawn explanations – completely devoid of a single on-screen pixel – can be used to effectively explain social media concepts. I think GoAnimate could do much the same.
  • I’m hoping that there will be a way to download the cartoons you create, and/or upload them to your YouTube account – because I prefer to keep all my digital media stored more or less in the same place.
