  • music performance anxiety (MPA)
  • The concept of “flow”, describing the subjective psychological state in which a person is completely immersed and fully concentrated in an activity which is enjoyable and rewarding, is often associated with optimal functioning
  • Anxiety is generally regarded as having an antithetical relationship with flow
  • ...19 more annotations...
  • The clinical implications of this negative association between MPA and flow suggest that a two-pronged approach focusing on facilitating flow and positive functioning as well as reducing pathological MPA may bring about improvements in the performer’s subjective performing experienc
  • Seligman’s (2011) most recent model of well-being, from the field of positive psychology, understands well-being as comprising five elements: Positive emotion, Engagement, Relationships, Meaning and Achievemen
  • There is a substantial body of Music Performance Anxiety (MPA) research providing evidence that MPA is a debilitating phenomenon (Kenny, 2011) which can affect musicians at any stage of their careers, from highly experienced professional performers (Fishbein, Middlestadt, Ottati, Straus, & Ellis, 1988; Kenny, Driscoll, & Ackerman, 2014) through to child beginners
  • Anxiety is often described as having an antithetical relationship to the experience of flow (Csikszentmihalyi, 1975), and it has been suggested that fostering techniques for facilitating flow may provide a powerful tool for reducing MPA and encouraging optimal performance
  • “when performance anxiety was highest, flow was lowest and vice versa … the presence of one minimises the magnitude of the other” (Fullager et al., 2013, p. 251), and a recent study found evidence of a strong, significant negative association between flow and MPA amongst 200 professional orchestral musicians (Cohen & Bodner, 2018), supporting Kirchner et al.’s (2008) earlier findings with music students
  • Investigations of the efficacy of existing methods for treating MPA indicate that Cognitive Behavioural Therapy based interventions are most effective (for an overview, see Burin & Osorio, 2016).
  • However, evidence suggests that pharmacological methods, particularly beta-blockers, are most commonly used, often in the absence of medical supervision (Cohen & Bodner, 2018; Kenny et al., 2014) and that the subject of MPA is still stigmatised, with many musicians and teachers unwilling to talk openly about it
  • Csikszentmihalyi’s nine dimensions of flow as follows
  • Although there was an increase in flow over time, this was not significant, F(1, 20) = 4.27, p > .05, η2 =.18, and there was no evidence of a significant interaction between group and time, F(1, 20) = 0.56, p > .05, η2 = .03, indicating that the hypothesis that there would be an increase in self-reported levels of flow in the intervention group, was not supported.
  • Figure 4. Judge-rated musical performance quality and signs of performance anxiety in the intervention group.
  • These results support the fourth hypothesis that there would be an increase in judge-rated PQ and a decrease in judge-rated SPA.
  • Results showed evidence of a significant negative association between MPA and flow, and three out of the four study hypotheses were supported: the music performance skills intervention was found to be effective in reducing pre-/post-test MPA in the intervention group compared to the wait-list control group; there were significant improvements in positive and negative affect and state anxiety associated with the performance situation in the intervention group; and there were significant improvements in judge-rated PQ and behavioural signs of performance anxiety. However, there was no significant change in pre-/post-test measures of flow. These findings will now be discussed in more detail.
  • This supports the understanding of MPA as a specific type of anxiety, where the performer suffers from MPA without necessarily being generally anxious or impaired in any other areas of his/her life (Clark & Williamon, 2011; Hoffman & Hanrahan, 2011) and corresponds to Kenny’s (2011) description of the first and most mild of three types of MPA (for full coverage of this issue, see Kenny, 2011).
  • Thus, the absence in improvement in levels of flow in the current study could also be due to the low average hours of daily practice reported
  • The increases in participants’ positive affect and decreases in negative affect after the second simulated performance compared to the first indicate that the intervention was effective in facilitating positive emotion, the first component of Seligman’s (2011) PERMA model of well-being
  • Evidence of improvements in judge-rated performance quality indicate that the intervention was also effective in facilitating the fifth (Achievement) component of the PERMA model.
  • “Ironically, it may be that the last people to receive some benefit from the therapeutic value of music may be the musicians themselves” (Brodsky, 1996, p. 95).
  • Hopefully, such an approach will enable developing musicians to acquire the skills necessary to enjoy satisfying, successful and healthy lives as performing musicians, in which the threat of debilitating MPA and the need to recourse to beta-blockers are a thing of the past.

      Rubbish. Teachers need to teach. These vacuous ideas that students know as much as teachers and we all teach each other have led to a dangerous decline in educational standards in the West. People do not process in a vacuum; they need to know the content before they can engage in that 'higher-order thinking' Blooms gunk. These theories are an excuse for teachers who don't know their subjects to feel less shamed at their ignorance.

    Do you speak/teach from a pulpit? Take a look at "No More Learners" What was your first thought(s) when viewing this? Does 'talking down' to learners go on? Perhaps it goes on some; but, I don't think a great deal today. Who out there thinks they are or were ever in the pulpit? I was in the 70's and changed in 80's. There are too many smarter learners out there. Please consider leaving your IMHO comment as a note.

  • “Responders Are Taught, Not Born”
  • We contend that student writers will see greater value in peer response if they develop tools that allow them to participate more actively in the feedback process. With teaching suggestions like those above, writers can learn how to re-flect on their experiences with peer response. They can also learn to identify their needs as writers and how to ask questions that will solicit the feedback they need.

Bet-ter than I do?”>“I’m not really sure if I’m supposed to talk or ask questions when someone is giving me feedback about my work, so I don’t really do anything. They write stuff on my paper.

Questions like “Am I getting off topic in the introduction when I talk about walking my sister to the corner on her first day of school?” or “Does my tone on page 3 seem harsh?

    "Well-being has moved up the political and managerial agenda as well-being concerns have grown. In many schools 'over-doing it' has become a badge of honour and created an unsustainable arms-race of burn-out. But will this renewed focus by educational leaders make any difference? Does it need to, or sure we be responsible for our own well-being and for those around us?"

      This is, I think, why I'm more keen on today's social networks than I am on games -- games do not provide deep emotional support.

  • According to Putnam, time spent with relatively passive and disengaging media has come at the expense of time spent on vital community-building activities.
  • The evidence to date is mixed
  • A core problem on both sides of the debate is an underlying assumption that all Internet use is more or less equivalent
    • Adrienne Michetti
      Adrienne Michetti on 19 Nov 09
       
      SO True
  • It would be more plausible and empirically rigorous, then, to consider how specific forms of Internet activity impact civic and social engagement as a result of their particular underlying social architectures
  • combining conclusions from two different lines of MMO research conducted from two different perspectives—one from a media effects approach, the other from a sociocultural perspective on cognition and learning.
  • By providing spaces for social interaction and relationships beyond the workplace and home, MMOs have the capacity to function as one form of a new "third place" for informal sociability much like the pubs, coffee shops, and other hangouts of old.
  • loosely structured by open-ended narratives
  • They are known for their peculiar combination of designed "escapist fantasy" and emergent "social realism"
  • from two research projects: one an examination of the media effects of MMOs, the other an ethnographic study of cognition and culture in such contexts.

  • brick-and-mortar "third places" in America where individuals can gather to socialize informally beyond the workplace and home
  • the exaggerated self-consciousness of individuals.
  • In what ways might MMOs function as new third places for informal sociability?
  • virtual environments have the potential to function as new (albeit digitally mediated) third places similar to pubs, coffee shops, and other hangouts.
  • in this section we analyze the structural form of MMOs that warrants this "third place" assertion.
  • eight defining characteristics of third places
  • there is no default obligation
  • To oblige any one person to play requires that explicit agreements be entered into by parties
  • the default assumption is that no one person is compelled to participate legally, financially, or otherwise.
  • Unless one transforms the virtual world of the game into a workplace (e.g., by taking on gainful employment as a virtual currency "farmer" for example, Dibbell, 2006; Steinkuehler, 2006a) or enters into such agreement, no one person is obligated to log in
    • Adrienne Michetti
      Adrienne Michetti on 19 Nov 09
       
      and this is why, in my opinion, you will never see games in school. The game cannot be the Third Place because school is a Second Place.
  • Yee's (2006) interviews also reveal that individuals who game with romantic partners or family find that such joint engagement in the "other world" of MMOs allows them to redefine the nature and boundaries of their offline relationships, often in more equitable terms than what may be possible in day-to-day offline life
  • the relationships that play-partners have with one another offline are often "leveled" within the online world
  • an individual's rank and status in the home, workplace, or society are of no importance
  • appeal to people in part because they represent meritocracies otherwise unavailable in a world often filled with unfairness
  • conversation plays an analogous role
  • "In all such systems, linguistic interactions have been primary: users exchange messages that cement the social bonds between them, messages that reflect shared history and understandings (or misunderstandings) about the always evolving local norms for these interactions" (p. 22).
  • third places must also be easy to access
  • such that "one may go alone at almost any time of the day or evening with assurance that acquaintances will be there"
  • accessible directly from one's home, making them even more accommodating to individual schedules and preferences
  • barriers to initial access.
  • "What attracts a regular visitor to a third place is supplied not by management but by the fellow customer,"
  • "It is the regulars who give the place its character and who assure that on any given visit some of the gang will be there"
  • affective sense
  • As one informant satirically commented in an interview, "You go for the experience [points], you stay for the enlightening conversation.
  • engendering a sense of reliable mentorship and community stability.
  • Oldenburg argues that third places are characteristically homely, their d�cor defying tidiness and pretension whenever possible. MMOs do not fit this criterion in any literal sense
  • In neither of our investigations did the degree of formality exhibited by players within the game bear any relation to the degree of visual ornamentation of the players' immediate vicinity.
  • Thus, while the visual form of MMO environments does not fit Oldenburg's (1999) criterion of "low profile," the social function of those environments does.
  • Oldenburg (1999) argues that seriousness is anathema to a vibrant third place; instead, frivolity, verbal word play, and wit are essential.
  • The playful nature of MMOs is perhaps most apparent in what happens when individuals do bring gravity to the game.
  • the home-like quality of third places in rooting people
  • Participation becomes a regular part of daily life for players and, among regular gamemates such as guild members, exceptional absences (i.e., prolonged or unforeseen ones) are queried within the game or outside i

  • Are virtual communities really communities, or is physical proximity necessary?
  • Anderson (1991), who suggests that geographic proximity itself is neither a necessary nor sufficient condition for the emergence and preservation of "community."
  • Social capital (Coleman, 1988) works analogously to financial capital; it can be acquired and spent, but for social and personal gains rather than financial
  • operates cyclically within social networks because of their associated norms of reciprocity
  • bridging social capital is inclusive.
  • This form of social capital is marked by tentative relationships, yet what they lack in depth, they make up for in breadth.
  • On the one hand, bridging social capital provides little in the way of emotional support; on the other hand, such relationships can broaden social horizons or worldviews, providing access to information and new resources.
  • bonding social capital is exclusive.
  • social superglue.
  • it can also result in insularity.
  • shows that bridging and bonding social capital are tied to different social contexts, given the network of relationships they enable.
  • Virtual worlds appear to function best as bridging mechanisms rather than as bonding ones, although they do not entirely preclude social ties of the latter type.
  • One could argue that, if the benchmark for bonding social capital is the ability to acquire emotional, practical, or substantive support, then MMOs are not well set up for the task:
  • While deep affective relationships among players are possible, they are less likely to generate the same range of bonding benefits as real-world relationships because of players' geographic dispersion and the nature of third places themselves.
  • Despite differences in theoretical grounding and methodologies, our conclusions were remarkably similar across complementary macro- and micro-levels.
  • It is worth noting, however, that as gamers become more involved in long-term social networks such as guilds and their activities become more "hardcore" (e.g., marked by participation in large-scale collaborative problem-solving endeavors such as "raids" into difficult territories or castle sieges), the function of MMOs as "third places" begins to wane.
  • It may be, then, that the structure and function of MMOs as third places is one part of the "life cycle" for some gamers in a given title.
  • In such cases, MMOs appear to enable a different kind of sociability, one ostensibly recognizable as a "community" nonetheless.
  • However, our research findings indicate that this conclusion is uninformed. To argue that MMO game play is isolated and passive media consumption in place of informal social engagement is to ignore the nature of what participants actually do behind the computer screen
  • Perhaps it is not that contemporary media use has led to a decline in civic and social engagement, but rather that a decline in civic and social engagement has led to retribalization through contemporary media (McLuhan, 1964).
  • Such a view, however, ignores important nuances of what "community" means by pronouncing a given social group/place as either wholly "good" or "bad" without first specifying which functions the online community ought to fulfill.
  • Moreover, despite the semantics of the term, "weak" ties have been shown to be vital in communities, relationships, and opportunities.
  • is to what extent such environments shift the existing balance between bridging and bonding
  • In light of Putnam's evidence of the decline of crucial civic and social institutions, it may well be that the classification "lacking bridging social capital" best characterizes the everyday American citizen. T
  • Without bridging relationships, individuals remain sheltered from alternative viewpoints and cultures and largely ignorant of opportunities and information beyond their own closely bound social network.
  • it seems ironic that, now of all times, we would ignore one possible solution to our increasingly vexed relationship with diversity.

  • If student work that incorporates, modifies, and re-presents existing media content meets the transformativeness standard, it can be distributed to wide audiences under the doctrine of fair use.
  • When sharing is confined to a delimited network, such uses are more likely to receive special consideration under the fair use doctrine
  • there are no cut-and-dried rules (such as 10 percent of the work being quoted, or 400 words of text, or two bars of music, or 10 seconds of video).
  • Transformativeness, a key value in fair use law, can involve modifying material or putting material in a new context, or both
  • Copyright Act itself makes it clear that educational uses will often be considered fair because they add important pedagogical value to referenced media objects.
  • If educators or learners want to share their work only with a class (or another defined, closed group) they are in a favorable position
  • if work is going to be shared widely, it is good to be able to rely on transformativeness
  • courts have found that asking permission and then being rejected has actually enhanced fair use claims.
  • We don’t know of any lawsuit actually brought by an American media company against an educator over the use of media in the educational process
  • Lack of clarity reduces learning and limits the ability to use digital tools. Some educators close their classroom doors and hide what they fear is infringement; others hyper-comply with imagined rules that are far stricter than the law requires, limiting the effectiveness of their teaching and their students’ learning.

The oldest son has ADHD. His grandmother was a math teacher and I am a math teacher, but yet that was the subject he failed almost each year and had to go to summer school. He had the same parents and the same environment as his younger brother, but he was lacking the drive that is born in you. I won't go into the differences of the other 4 just to say that the good Lord gifted me with 3 ADHD children when not much was known about it (the oldest is 44). Every child is different and parents must learn not to judge one by the others, just like teachers must not assume that about siblings they teach. A parent can be their to help and try to point them in the right direction with the right work ethics in school, but the bottom line is how much the child cares and wants to achieve. The envolved parent can help the child that sits on the fence and can go on either side, but the ultimate choice is going to be the child's. It is the same with church. You can take the child to church every Sunday, but when they get older it is their decision how to direct their life. I am not saying that a parent shouldn't try every day to give the guidance their children need and deserve, but you can't beat yourself up when things don't go the way you think they should. All a parent can do is standby their child and give them all the love they can and to know that sometimes that is not enough for the child."

  • First, students tend to lose interest in whatever they’re learning. As motivation to get good grades goes up, motivation to explore ideas tends to go down. Second, students try to avoid challenging tasks whenever possible. More difficult assignments, after all, would be seen as an impediment to getting a top grade. Finally, the quality of students’ thinking is less impressive. One study after another shows that creativity and even long-term recall of facts are adversely affected by the use of traditional grades.

    • Terie Engelbrecht

      Very true; especially the "avoiding challenging tasks" part.
  • Unhappily, assessment is sometimes driven by entirely different objectives--for example, to motivate students (with grades used as carrots and sticks to coerce them into working harder) or to sort students (the point being not to help everyone learn but to figure out who is better than whom)
  • Standardized tests often have the additional disadvantages of being (a) produced and scored far away from the classroom, (b) multiple choice in design (so students can’t generate answers or explain their thinking), (c) timed (so speed matters more than thoughtfulness) and (d) administered on a one-shot, high-anxiety basis.
  • ...36 more annotations...
  • The test designers will probably toss out an item that most students manage to answer correctly.
  • the evidence suggests that five disturbing consequences are likely to accompany an obsession with standards and achievement:
  • 1. Students come to regard learning as a chore.
  • intrinsic motivation and extrinsic motivation tend to be inversely related: The more people are rewarded for doing something, the more they tend to lose interest in whatever they had to do to get the reward.
  • 2. Students try to avoid challenging tasks.
  • they’re just being rational. They have adapted to an environment where results, not intellectual exploration, are what count. When school systems use traditional grading systems--or, worse, when they add honor rolls and other incentives to enhance the significance of grades--they are unwittingly discouraging students from stretching themselves to see what they’re capable of doing.
  • 3. Students tend to think less deeply.
  • 4. Students may fall apart when they fail.
  • 5. Students value ability more than effort
    • Deb White Groebner
      Deb White Groebner on 13 May 11
       
      This is the reinforcement of a "fixed mindset" (vs. (growth mindset) as described by Carol Dweck.
  • They seem to be fine as long as they are succeeding, but as soon as they hit a bump they may regard themselves as failures and act as though they’re helpless to do anything about it.
  • When the point isn’t to figure things out but to prove how good you are, it’s often hard to cope with being less than good.
  • It may be the systemic demand for high achievement that led him to become debilitated when he failed, even if the failure is only relative.
  • But even when better forms of assessment are used, perceptive observers realize that a student’s score is less important than why she thinks she got that score.
  • just smart
  • luck:
  • tried hard
  • task difficulty
  • It bodes well for the future
  • the punch line: When students are led to focus on how well they are performing in school, they tend to explain their performance not by how hard they tried but by how smart they are.
  • In their study of academically advanced students, for example, the more that teachers emphasized getting good grades, avoiding mistakes and keeping up with everyone else, the more the students tended to attribute poor performance to factors they thought were outside their control, such as a lack of ability.
  • When students are made to think constantly about how well they are doing, they are apt to explain the outcome in terms of who they are rather than how hard they tried.
  • And if children are encouraged to think of themselves as "smart" when they succeed, doing poorly on a subsequent task will bring down their achievement even though it doesn’t have that effect on other kids.
  • The upshot of all this is that beliefs about intelligence and about the causes of one’s own success and failure matter a lot. They often make more of a difference than how confident students are or what they’re truly capable of doing or how they did on last week’s exam. If, like the cheerleaders for tougher standards, we look only at the bottom line, only at the test scores and grades, we’ll end up overlooking the ways that students make sense of those results.
  • the problem with tests is not limited to their content.
  • if too big a deal is made about how students did, thus leading them (and their teachers) to think less about learning and more about test outcomes.
  • As Martin Maehr and Carol Midgley at the University of Michigan have concluded, "An overemphasis on assessment can actually undermine the pursuit of excellence."
  • Only now and then does it make sense for the teacher to help them attend to how successful they’ve been and how they can improve. On those occasions, the assessment can and should be done without the use of traditional grades and standardized tests. But most of the time, students should be immersed in learning.
  • the findings of the Colorado experiment make perfect sense: The more teachers are thinking about test results and "raising the bar," the less well the students actually perform--to say nothing of how their enthusiasm for learning is apt to wane.
  • The underlying problem concerns a fundamental distinction that has been at the center of some work in educational psychology for a couple of decades now. It is the difference between focusing on how well you’re doing something and focusing on what you’re doing.
  • The two orientations aren’t mutually exclusive, of course, but in practice they feel different and lead to different behaviors.
  • But when we get carried away with results, we wind up, paradoxically, with results that are less than ideal.
  • Unfortunately, common sense is in short supply today because assessment has come to dominate the whole educational process. Worse, the purposes and design of the most common forms of assessment--both within classrooms and across schools--often lead to disastrous consequences.
  • grades, which by their very nature undermine learning. The proper occasion for outrage is not that too many students are getting A’s, but that too many students have been led to believe that getting A’s is the point of going to school.
  • research indicates that the use of traditional letter or number grades is reliably associated with three consequences.

  • If you accept that Learning is a Conversation, and that some of the most powerful learning can take place in the process of conversing and exchanging ideas with others, then setting up ways to have as many of these conversations as possible seems like an obvious thing to do.
  • It might be easy to think that the people on the stage at conferences have the knowledge and that if we simply listen to them we will get wisdom, but the truth is that sometimes it just doesn't work like that, and even if it does, most of those ideas gather far more momentum once we start to internalise them through further conversation with others. Ideas beget ideas, one thing leads to another, and you often find some of the best, most useful ideas come to you not from what was said by a speaker, but from things that came to to you as a result of further conversation about what was said.  (by the way, the same logic applies in classrooms too!)
  • If we limit our notion of learning to the "official" channel - the teacher, the textbook, the syllabus - we miss so much. Yes, learning happens at school, but what about outside school? Yes, learning happens in the classroom, but what about outside the classroom? Yes, learning happens in the act of "being taught", but what about when we are not "being taught"?

  • if we acknowledge that creativity in education is important, then how can we teach kids to be creative if we continue to focus on just regurgitating standard answers to standard questions, year after year.

    We are all time travelers... drifting through time at a steady pace, one moment at a time. In what direction are we moving through time? Or does time move through us? How many dimensions of time are there? Though slightly allegorical, three-dimensional time offers physics new parameters, accounting for conventional and exotic physical phenomena, while maintaining the conservation of energy and symmetry groups found in physical law.  I began playing with the idea that all of physics could be reduced to just interactions between spatial and temporal coordinates. I wondered if inertia and momentum might be composed strictly of temporal components. This would require extra time dimensions. Could inertia or momentum be used as indicators of multi-dimensional time? What about charge, spin, and other properties of matter? Answers to some of these questions appeared to reside in neutrino research, specifically neutrino flavor oscillation.  The universality between Thermodynamics and Temporal Mechanics can reduce the fundamental forces of nature into a single expression, a new equivalence principle, which can be used as the generator for the evolution of time. Once Quantum Mechanics is seen through the lens of three-dimensional time, the EPR paradox looses its mystique. The speed of light may be restricted to a set speed limit within each individual frame of reference, however, frames of reference can undergo periods-of-time at varying rates of the passage-of-time. If the positive side of absolute zero is a state of condensed matter, what is on the negative side of absolute zero? Uncondensed matter?  The anti-matter aspect of the Dirac equations may have been misinterpreted. The convention is to assume that "matter" is composed of "particles" distinctly different from "antimatter" composed of "antiparticles". The assumption of one time dimension locks in this interpretation of the Dirac Equations. However, the uniform production of particles and antipa

NaturalScience senseperception paradigm

shared by Gareth Jones on 19 May 18 - No Cached
  • 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.

  • 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

  • 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

      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

      I love this concept!  The focus is on the process of learning.  Doesn't that also help to identify the way we learn as well as the progress of the learning?

      The down side of this is that there also has to be some sort of focus on the importance of completing what is started.  Everything might not have to have an end product but some things certainly should have!
  • At times it has been deeply admonished and hidden from view. Individuals who failed were to be shunned or punished. At other times failure was to be avoided by setting the bar for success so low that failure was impossible. The result of this movement was that success became meaningless, achievable by all without risk and through little effort.

      The generation when who were deeply admonished and hidden is older and most are relieved that this is no longer the case.  The generation who were shunned or punished seem to still be a part of the mainstream but most have embraced that this is no longer the case.  The generation who were part of the low expectations with failure impossible seem to be the predominance of the population now and we are seeing that there is no concept of consequences, no motivation toward high achievement, and an attitude of entitlement.

      This seems like we are evolving but moving more in a cyclical fashion and thinking more like the early innovators in our country - Jefferson, Franklin, Ford, Bell - We see a need for something and strive to create it - marking our failures as a way of knowing, "well that won't work so lets find something that will."
  • A culture that accepts failure as a part of the learning process will need to take time to celebrate the steps taken towards learning as much as it celebrates the finished product.
  • A digital work of art, of music of writing is never truly finished, it grows and transforms over time.

      Transformation from the mindset of this is done, this if finished, this is the final draft to here is where we are at this point but it may be revisited, revised, refined at a later time.
  • mistakes are a sign that the learning is not pitched at a level below the needs of the students; if the students are not making mistakes when they engage with new learning the expectation has been set too low.
  • What must be avoided is a belief that mistakes are to be accepted without an equal emphasis on identifying and understanding their causes.

      Identify and understand the causes of mistakes so that another attempt can be made at correcting them and progress is made!

    There is a danger in seeking finished perfection in all that we do. There is a risk that our students will focus solely on the attributes that define a finished piece and overlook the importance of the process that leads to it.

      This would be a great activity for introductions.
  • One of my colleagues asks her students to sketch their names using a typeface that conveys something about themselves
  • One thing I do is bring in the style manuals from different local companies and show students how each company expects different things

  • Students in all disciplines are more than capable of producing and analyzing visual work in amazingly rich and complex ways.
  • many faculty members continue to specify detailed formatting requirements for student writing.
  • Your paper must be double-spaced, 12 point Times New Roman, with one-inch margins.
  • Such draconian formatting requirements stifle students’ creativity and cut off any critical thinking about what should be a crucial part of any writing-intensive classroom, namely visual design.
  • Teaching Document Design, Not Formatting Requirements
  • well-meaning and thoughtful teachers establish hard and fast formatting rules that may make their lives easier, but do a disservice to their students.
  • By making these requirements, we are telling them not to think critically—or even at all—about the visual layout of their documents.
  • We are telling them we value conformity over creativity, practicality over originality, our needs over theirs.
  • It all starts with students recognizing that design is a part of what they do when they write.
  • the rules we give our students should be negotiable, and in order for them to be negotiable, we need to talk to our students about those rules, why they exist, what the consequences of breaking or following them are, and so on.
  • Your paper should be readable and take into consideration the needs of your audience.  Most importantly, though, you should have fun and be creative with your design.
  • Mr. Stanley on 05 Dec 10
     
    Teachers need to allow their students more room to creatively use visual design, and at the same time, teach students to be aware. Forcing students to follow exact formatting requirements is counterproductive.
