Myers-Briggs Personality Types in Business | Infographic - 10 views

  •  
    People experience the world using four principal psychological functions-sensation, intuition, feeling, and thinking-according to Swiss psychiatrist Carl Gustav Jung, the founder of analytic psychology. Based on Jung's concepts of introversion and extroversion and his theory of personality types, US mother and daughter team Myers and Briggs created the Myers-Briggs Type Indicator (MBTI) personality test based on the following sets of four dichotomies: Introvert (I)/Extrovert (E) Intuitive (N)/Sensory (S) Thinking (T)/Feeling (F) Judging (J)/Perceiving (P)

Digital Life - Report: More kids 'cyberbaiting' teachers - 141 views

  •  
    This report seems short on research and long on guesses that seems to be trying to link sensational but unrelated facts. I see little attempt made to define the terms. The teachers I know who use facebook to communicate with students do so to keep students thinking about their classwork and deadlines. The "cyberbaiting" which the reporter tries to link to facebook friending with a "perhaps"...would rarely be related. From what I've seen, kids cyberbait the teachers who are least likely to use or understand social media at all. I would imagine that a teacher who is online with students would be least likely to be a target. All this is unoffical guess, but the article does little to provide me with facts or information to contradict this.

Brief meditative exercise helps cognition - 5 views

  • "Simply stated, the profound improvements that we found after just 4 days of meditation training- are really surprising," Zeidan noted. "It goes to show that the mind is, in fact, easily changeable and highly influenced, especially by meditation."
  • The meditation training involved in the study was an abbreviated "mindfulness" training regime modeled on basic "Shamatha skills" from a Buddhist meditation tradition
  • "Findings like these suggest that meditation's benefits may not require extensive training to be realized, and that meditation's first benefits may be associated with increasing the ability to sustain attention,"
  • ...5 more annotations...
  • seems to be strong evidence for the idea that we may be able to modify our own minds to improve our cognitive processing -- most importantly in the ability to sustain attention and vigilance -- within a week's time."
  • Both groups also improved following the meditation and reading experiences in measures of mood, but only the group that received the meditation training improved significantly in the cognitive measures. The meditation group scored consistently higher averages than the reading/listening group on all the cognitive tests and as much as ten times better on one challenging test that involved sustaining the ability to focus, while holding other information in mind. "The meditation group did especially better on all the cognitive tests that were timed," Zeidan noted. "In tasks where participants had to process information under time constraints causing stress, the group briefly trained in mindfulness performed significantly better."
  • participants were instructed to relax, with their eyes closed, and to simply focus on the flow of their breath occurring at the tip of their nose. If a random thought arose, they were told to passively notice and acknowledge the thought and to simply let 'it' go, by bringing the attention back to the sensations of the breath."
  • "The simple process of focusing on the breath in a relaxed manner, in a way that teaches you to regulate your emotions by raising one's awareness of mental processes as they're happening is like working out a bicep, but you are doing it to your brain. Mindfulness meditation teaches you to release sensory events that would easily distract, whether it is your own thoughts or an external noise, in an emotion-regulating fashion.
  • "This kind of training seems to prepare the mind for activity, but it's not necessarily permanent," Zeidan cautions. "This doesn't mean that you meditate for four days and you're done -- you need to keep practicing."

Mindfulness meditation benefits and changes brain structures in 8 weeks - 2 views

  • In a study published in the January 30 edition of Psychiatry Research: Neuroimaging, Massachusetts General Hospital (MGH) researchers concluded that an eight week mindful meditation practice produced measurable changes in participants' brain regions associated with memory, sense of self, empathy and stress. This is the first study to document meditation-produced changes in the brain's grey matter over time.
  • Previous research has documented structural differences between the brains of experienced mediation practitioners and individuals with no history of meditation. These brain changes included thickening of the cerebral cortex in areas associated with the integration of emotions and attention. However, earlier studies were unable to document that those brain differences were actually caused by meditation.
  • mindfulness meditation (which focuses on nonjudgmental awareness of sensations, feelings and state of mind)

The Classroom » Using Diigo for Organizing the Web for your Class - 13 views

  • Using Diigo for Organizing the Web for your Class 31 07 2007 A good friend of mine, Randy Lyseng, has been telling people of the tremendous power and educational value that can be gained from social bookmarking in the classroom. His personal favourite is Diigo. My preference is a social bookmarking tool called http://diigo.com. With diigo, you can highlight, add stick notes and make your comments private or public. (Randy Lyseng, Lyseng Tech: Social Bookmarking, November 2006) After listening to Randy praise Diigo at every opportunity, I finally started playing with the site (and corresponding program, more on that in a bit) this summer (I know Randy - I’m slow to catch on…)As I started to play with the system, my mind started reeling with all the possibilities. First off, like any other social bookmarking tool, Diigo allows you to put all your favorites/bookmarks in one “central” location. Students can access them from ANY computer in the world (talk about the new WWW: whatever, whenever, where ever). They just open up your Diigo page, and there are all the links. But that’s just the tip of the iceberg. Diigo’s power lies in it’s group annotations. That’s right, people can now write in the margins of webpages. You can highlight passages of interest, write notes, and even write a blog entry directly from another webpage, quoting passages right from the original text. Sounds great - but to do all that it must be complicated right? Nope. To use these advanced features all you need to do is run the Diigo software. This can either be done using a bookmarklet or by downloading and installing the Diigo toolbar. While both have basically the same features, the toobar is less finicky, and allows you to use contextual menus to access features quickly. I also find the toolbar’s highlighting and sticky notes to be easier to read. Ok fine… I can leave notes on webpages - so what? Here’s an example. I’m thinking about having my 7B’s record radio plays. I’ve looked them up online and found many scripts from all the old classics available. However many also contain the old endorsements from tobacco and other companies. So I go to a play that I’d like to my students to record and highlight the old commercial. If they’re using diigo when they access this page they’ll see the same text highlighted in pink, and when they mouse over the highlighted text they’ll get a hidden message from me - “I’d like you to write a new advertisement for this section. What other advertisement do you think we could write for here? Write an ad for a virtue or trait that you think is important. For example - “Here’s a news flash for every person in Canada. It’s about a sensational, new kind of personality that will make you the envy of all those around you. It’s call trustworthiness. Why with just a pinch of this great product….” They now have a writing assignment to go along with the recording of the radio play. Adding assignments is just one possibility. You can ask questions about the site, or have students carry on conversations about the text. Perhaps about the validity of some information. These notes can be made private (for your eyes only), public, or for a select group of people. You could use the same webpage for multiple classes, and have a different set of sticky notes for each one! Diigo will also create a separate webpage for each group you create, helping you organize your bookmarks/notes further! This technology is useful for any class, but I think is a must have for any group trying to organize something along the lines of the 1 to 1 project. I’m hoping to convince all the core teachers to set up a group page for their classes, and organize their book marks there! I’ve already started one for my 7B Language Arts Class! One of the first questions I was asked when I started looking at this site, and more importantly at the bookmarklets and toolbar was is it secure? Will it bring spyware onto our systems? How about stability? I’ve currently been running the Diigo bookmarklet and toolbar on 3 different browsers, Explorer, Firefox, and Safari (sorry, there’s no Safari toolbar yet), across 4 different computers and 2 different platforms with no problems. I’ve also run every virus and spyware scan I can think of, everything checks out clean. I’ve also done an extensive internet check, and can’t find any major problems reported by anyone else. To my mind it’s an absolutely fantastic tool for use in the classroom. Thanks Diigo! And thanks Randy for pointing me in the right direction!

(PDF) A Systematic Review of Treatments for Music Performance Anxiety - 2 views

  • Four other studies (three of which are dissertations) assessed behavioral treatments forMPA on music students. Grishman (1989) and Mansberger (1988) used standard musclerelaxation techniques, Wardle (1969) compared insight/relaxation and systematic desensi-tisation techniques, and Deen (1999) used awareness and breathing techniques
  • A systematic review of all available treatment studies for music performance anxiety was undertaken.
  • reported that 24% of musicians frequently suffered stage fright, defined in this study as themost severe form of MPA, 13% experienced acute anxiety and 17% experienceddepression.
  • ...24 more annotations...
  • 59% of musicians in symphony orchestras reported performance anxiety severe enough toimpair their professional and/or personal functioning.
  • A recent study indicated that MPA is not limited to orchestralmusicians, showing that opera chorus artists are also prone to high levels of performanceanxiety
  • However, since not allperformers suffer the same degree of MPA, or indeed report the same levels of occupationalstress, individual differences in a range of psychological characteristics are likely to accountfor variations in the degree to which musicians experience symptoms
  • A large number of treatment modalities (e.g., behavioral, cognitive, pharmacological andcomplementary) has been developed for music performance anxiety (MPA)
  • However, areview of this literature indicates that the field is still in its infancy with respect to theconceptual and theoretical formulations of the nature of MPA and its empiricalinvestigation.
  • Anxiety may be triggered by conscious,rational concerns or by cues that trigger, unconsciously, earlier anxiety producingexperiences or somatic sensations.
  • These findings suggest that multi-modal interventions are needed toaddress the multiple difficulties experienced by test anxious individuals.
  • with some focusing on behavioral change, some on cognitivechange, others on reduction of physiological symptoms through the use of pharmacotherapy,and some on idiosyncratic formulations
  • For drug studies, the keywords were beta-blocker [Beta blockers block the effect ofadrenaline (the hormone norepinephrine) on the body’s beta receptors. This slows downthe nerve impulses that travel through the heart. As a result, the resting heart rate is lower,the heart does not have to work as hard and requires less blood and oxygen
  • Brodsky (1996) and Nube´(1991) were most useful.
  • The interventionsassessed included systematic desensitization, progressive muscle relaxation, awareness andbreathing and behavioural rehearsal
  • In summary, behavioral treatments do appear to be at least minimally effective in thetreatment of MPA, although the heterogeneity of the treatment approaches employedmakes it difficult to isolate consistent evidence for the superiority of any one type ofbehavioral intervention
  • Two studies (see Tables II and IV) assessed the therapeutic effect of cognitive techniquesalone on MPA.
  • A dissertation by Patston (1996) reported a comparison of cognitive (e.g.positive self-talk, etc.) and physiological strategies in the treatment of MPA. No significantimprovements on vocal and visual manifestations of performance anxiety were found foreither treatment or control groups. However, the sample consisted of only 17 operastudents who were not specifically selected on the basis of their MPA severity, and theintervention was conducted by the author, a singer and teacher, who had no training inpsychology.
  • Three studies (see Table III) assessed the therapeutic effect of cognitive-behavioralstrategies on MPA. Harris (1987), Roland (1993), and Kendrick et al. (1982) all reportedthat standard CBT techniques were effective in the treatment of MPA in studentsspecifically selected for study because of the severity of their MPA.
  • Harris (1987) and Roland(1993) reported that CBT led to reductions in state anxiety as measured by the STAI,although Kendrick et al. (1982) failed to find a significant difference between treatment andcontrol groups on this measure.
  • The evidence for improvements in MPA following CBT is quite consistent, althoughfurther studies with larger samples are needed to confirm this evidence.
  • Beta-blockers have become increasingly popular among performers in recent years. Forexample, Lockwood (1989), in a survey of 2,122 orchestral musicians, found that 27% usedpropranolol to manage their anxiety prior to a performance; 19% of this group used thedrug on a daily basis.
  • Nube´ (1991) identified nine studies examining the effects of various beta-blockers(Atenolol, Metopolol, Nadolol, Oxprenolol, Propranolol, Pindolol) on MPA.
  • The findings regarding the effects of beta blockers on otheroutcome measures were less conclusive.
  • A rigorous definition of MPA is needed to advance treatment. However, defining MPA as asocial anxiety (social phobia) using criteria set out in DSM-IV-TR (APA, 2000) as theinclusion criteria may be too restrictive, particularly if the musician presenting for treatmentexperiences MPA as a focal anxiety (ie does not meet other criteria for social anxiety).
  • Few ofthe intervention studies reviewed acknowledged that performers need a certain amount ofarousal or anxiety to maximise their performance.
  • None of the studies could be pooled in a meta-analysis primarily because too fewprovided sufficient data to calculate effect sizes, use of diverse subject groups andtreatments, duration and intensity of treatment, and use of disparate outcome measures
  • In conclusion, the literature on treatment approaches for MPA is fragmented, incon-sistent, and methodologically weak. These limitations make it difficult to reach any firmconclusions about the effectiveness of the various treatment approaches reviewed. Forsignificant progress to be made, future research will require a clear definition of MPA,consistency and strength in methodology, and the development of robust and appropriateoutcome measures.

How Google Interferes With Its Search Algorithms and Changes Your Results - WSJ - 17 views

  • a shift from its founding philosophy of “organizing the world’s information,” to one that is far more active in deciding how that information should appear.
  • Google keeps blacklists to remove certain sites or prevent others from surfacing in certain types of results. These moves are separate from those that block sites as required by U.S. or foreign law,
  • Far from being autonomous computer programs oblivious to outside pressure, Google’s algorithms are subject to regular tinkering from executives and engineers who are trying to deliver relevant search results, while also pleasing a wide variety of powerful interests and driving its parent company’s more than $30 billion in annual profit.
  • ...4 more annotations...
  • Google made more than 3,200 changes to its algorithms in 2018, up from more than 2,400 in 2017 and from about 500 in 2010
  • testing showed wide discrepancies in how Google handled auto-complete queries and some of what Google calls organic search results
    • Martin Leicht
       
      Alternatives - Microsoft's BING - DuckDuckGo and Yahoo. check them out when you get time
  • Google said 15% of queries today are for words, or combinations of words, that the company has never seen before, putting more demands on engineers to make sure the algorithms deliver useful results.
    • Martin Leicht
       
      How do you connect your post/content to future searches? Tagging only gets you so far. Thus, Google "tinkers" with the algorithm to product "the best" results. Interesting & concerning!
  • ALGORITHMS ARE effectively recipes in code form, providing step-by-step instructions for how computers should solve certain problems. They drive not just the internet, but the apps that populate phones and tablets.
    • Martin Leicht
       
      Yet, we never (almost never) eat the same thing (recipe) twice in a day. We indulge ourselves with comfort food, yes. And we seek out new taste sensations.
