  • The World Health Organization (WHO) estimates that exposure to smoke from the simple act of cooking is the fifth worst risk factor for disease in developing countries, and causes almost two million premature deaths per year – exceeding deaths attributable to malaria or tuberculosis.
  • Women in developing countries are also at risk of head and spinal injuries, pregnancy complications, and maternal mortality from the strenuous task of carrying heavy loads of firewood or other fuels. Frequent exposure to cookstove smoke can also cause disabling health impacts like cataracts, which affect women more than men, and is the leading cause of blindness in developing countries.
  • Rudimentary wood-fired cookstoves and open fires emit fine particles, carbon monoxide, and other pollutants at levels up to 100 times higher than the recommended limits set by WHO

  • A randomized-control study in Guatemala led by the University of California, Berkeley, found that halving exposure to indoor air pollution with a chimney stove brought about a reduction in severe pneumonia, and that larger reductions in exposure had more pronounced effects. A systematic review of all available studies on the link between solid fuel use and child pneumonia has found an almost doubling of risk for those exposed.
  • Burns from open fires and unsafe cookstoves are another insidious risk faced by poor households dependent on kerosene, open fires, and unstable metal or clay cookstoves, contributing to a substantial percentage of the estimated 300,000 burn deaths that occur annually
  • While the link between exposure to cookstove smoke and a wide range of health problems such as pneumonia, chronic obstructive pulmonary disease, and lung cancer is well established, the current body of evidence linking cookstoves with other potentially important health effects is compelling but less documented
  • Nearly all of the existing evidence is based on observational studies that compare groups using open fires and traditional cookstoves with those using cleaner fuels, with very little being directly obtained from studies that directly measure the effects of interventions.
  • More evidence is needed to demonstrate that the levels of exposure reduction delivered by clean cookstove and fuels will result in declines in related illnesses and deaths.

Mindfulness in the Classroom by @Ed_Tmprince - 26 views

  •  
    "The development of mindfulness has, at its heart, the reduction of stress hormone levels. Teaching children a number of Mindfulness strategies allow children to find the ones that best meet their needs and successfully reduces their stress and anxiety. Massage and the power of touch are naturally relaxing and are ways to reduce these stress hormones. Maria Hernandez-Reid is a researcher at the Touch Research Institute. She says that the lowering of stress hormones not only reduces the feelings of anxiety but also supports a healthier immune system."

(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.

Obama's War on Inequality - The New York Times - 16 views

  • what can policy do to limit inequality? The answer is, it can operate on two fronts. It can engage in redistribution, taxing high incomes and aiding families with lower incomes. It can also engage in what is sometimes called “predistribution,” strengthening the bargaining power of lower-paid workers and limiting the opportunities for a handful of people to make giant sums.
  • We can see this in our own history. The middle-class society that baby boomers like me grew up in didn’t happen by accident; it was created by the New Deal, which engineered what economists call the “Great Compression,” a sharp reduction in income gaps.
  • Obamacare provides aid and subsidies mainly to lower-income working Americans, and it pays for that aid partly with higher taxes at the top. That makes it an important redistributionist policy — the biggest such policy since the 1960s.

  • between those extra Obamacare taxes and the expiration of the high-end Bush tax cuts made possible by Mr. Obama’s re-election, the average federal tax rate on the top 1 percent has risen quite a lot. In fact, it’s roughly back to what it was in 1979, pre-Ronald Reagan, something nobody seems to know.
  • What about predistribution? Well, why is Mr. Trump, like everyone in the G.O.P., so eager to repeal financial reform? Because despite what you may have heard about its ineffectuality, Dodd-Frank actually has put a substantial crimp in the ability of Wall Street to make money hand over fist.
  • these medium-size steps put the lie to the pessimism and fatalism one hears all too often on this subject. No, America isn’t an oligarchy in which both parties reliably serve the interests of the economic elite.
  • Money talks on both sides of the aisle, but the influence of big donors hasn’t prevented the current president from doing a substantial amount to narrow income gaps — and he would have done much more if he’d faced less opposition in Congress.

Freakonomics » What Should Be Done About Standardized Tests? A Freakonomics Q... - 42 views

  • Gaston Caperton
  • Standardized tests have much in common with French fries. Both of them differ in composition as well as quality. French fries are available in numerous incarnations, including straight, curly, skins-on, skins-off, and, in recent years, with sweet potatoes. Regarding quality, of course, the taste of French fries can range substantially – from sublime to soggy. It’s really the same with standardized tests.
  • Take the No Child Left Behind Act, for instance, a federal accountability law requiring scads of standardized tests to be used in evaluating schools. Do you know that almost all of the standardized tests now being employed to judge school quality are unable to distinguish between well taught and badly taught students?

  • all schools – kindergarten through college – should employ exit exams allowing us to determine what students have actually learned. We owe it to our students to make sure that they’ve been properly taught.
  • Then there are the questions of what to do with the results. I have actually sat through an extended discussion of how we could use regression analysis to parse out the contribution different teachers made to a group of students’ performance on a set of standardized tests. The answer was, yes it was possible, and could in fact be used to award merit pay increases. But nobody left the room feeling very comfortable that there would be any gain in what we knew made for good teaching.
  • Roughly half of the nation’s students are taking tests under NCLB that are completely free of open-ended questions.
  • educators have a strong incentive to “teach to the test.” In this case, that means teaching low level skills at the expense of the more demanding material that everyone says students need to master in today’s complicated world.
  • But is it fair to give students what amounts to a counterfeit passport to college or work? And do such tests spur high school teachers and principals to aim high with their students? To both questions, the answer is, “No.” In most states today, high school exit tests serve the same role as the standardized tests mandated by NCLB: they try to jack up the floor of student achievement in the nation’s schools. The best high school exit tests would be end-of-course exams akin to the “comprehensive” exams that many colleges and universities require students to pass in their majors before graduation – tests, that is, that would raise the ceiling of student achievement.
  • High-stakes testing has narrowed and dumbed down curricula; eliminated time spent on untested subjects like social studies, art, and even recess; turned classrooms into little more than test preparation centers; reduced high school graduation rates; and driven good teachers from the profession. Those are all reasons why FairTest and other experts advocate a sharp reduction in public school standardized testing and a halt to exit exams.

Princeton University - Kindle pilot results highlight possibilities for paper reduction - 20 views

  • However, e-readers must be significantly improved to have the same value in a teaching environment as traditional paper texts, participants said.
  • but they also said the ability to highlight directly on traditional text, to take notes and flip pages for ease in navigation suffers in the e-reader.
  • With hopes of assisting industry with the refinement of e-readers, and providing useful information to other academic institutions considering the devices, information and data from the one-time pilot have been compiled on an Office of Information Technology (OIT) website.
  • ...5 more annotations...
  • About 65 percent of the participants in the pilot said they would not buy another e-reader now if theirs was broken. Almost all the participants said they were interested in following the technology to its next stages, because they think a device that works well in academia would be worth having.
  • "I found the device difficult to use and not conducive to academic purposes," he said, and added, "But I can see how it can be used for pleasure reading."
  • What they liked best about the devices was: the battery life, the wireless connection and the portability of the e-reader; the fact that all the course reading was on one device; the ability to search for content; and the legibility of the screen, including the fact it could be read in full sunlight. The top five suggestions students had for improving e-readers were: improving the ability to highlight and annotate PDF files; improving the annotation tools; providing a folder structure to keep similar readings together; improving the highlighting function; and improving the navigation within and between documents on the reader (including having more than one document open at the same time for comparison).
  • "The Kindle would be better for an academic setting if the PDF format worked more effectively,"
  • "There would be a greater benefit realized if the devices could develop a better way to deliver the ubiquitous PDF document, which is used by many journals and libraries to deliver documents, and is the common format in which dissertations and theses are published and read by faculty," Temos said. "Some students said they spent a considerable amount of time printing PDF documents during the semester, and hardly ever referred back to them once the semester was over. I don't expect that is unusual."

  • The Buddha compared the mind to the strings of a lute (a guitar-like instrument): the lute can not be played if the strings are too tight or too loose. Similarly when attention is either too tight or too loose, you can't properly meditate. When attention is too loose, the mind wanders and you get lost in thought. Try narrowing your focus in different ways (e.g. just inhales instead of the whole breath, focus on a smaller area around your nose). Some people do a few minutes of yoga or loving kindness (metta) practice at the start of their meditation period to focus the mind, before switching to breath awareness meditation. Some people find focusing on sounds easier than focusing on breathing.
  • The goal is not to try to change anything, but to be aware of the desire to change it and then see if we can just relax and be ok with it even if it doesn't change. Are we trying to quiet the storm, or are we trying to find peace within the storm?

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.
