  • 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.

"And the effects are that exposure to violent video games increases the likelihood of aggressive behavior in both short-term and long-term contexts. Such exposure also increases aggressive thinking and aggressive affect, and decreases prosocial behavior."

    Martin van Hemert is a photographer based in Utah. He is actively involved in architectural, product, and fine art photography. Throughout his career, he has consistently been drawn to more labor intensive forms of the art, from baking films in hydrogen for astronomical photography, to long exposures and light painting of outdoor scenes photographed on 4×5 sheet films, to his current obsession with spherical panoramas. Born to a family of Dutch immigrants, he studied music at the University of Utah, following which he made the logical choice of a career in photography. Martin and his wife are the parents of three grown children and one un-grown grandchild, and live in rural Utah County with a small herd of horses. Their rodent control staff boasts 7 members.

    "School officials focused exclusively on bullying prevention efforts might want to consider the findings of a new study showing the highly damaging effects of multiple forms of victimisation on school climate. The study, published in the Journal of Child & Adolescent Trauma, measured the impact of polyvictimisation - exposure to multiple forms of victimisation - on school climate at the middle and high school levels. Results show that bullying, cyberbullying and harassment were significantly associated with decreases in perceptions of school safety, connection, and equity."

mooc learning education work competencies knowledge-management knowledge theory teaching research

shared by Thieme Hennis on 06 Jul 13 - No Cached
  • A critical assessment of mainstream of higher education reveals that universities spent most energy on delivery of knowledge. Application of knowledge is dominated by ‘near transfer’, which means that students learn to give practical examples of theoretical concepts. ‘Far transfer’ originates from the analysis and solving of real problems, without prior exposure to cues regarding relevant knowledge. It occurs in Schools that deploy problem- or project-based learning. Exchange of codified and practical knowledge is absent in general. It might take place during internships, but projects outside the university are better and moreover, they offer opportunity for integration with other learning processes.
  • A balanced and integrated approach of the three learning processes mentioned above is occurring in only few universities. Elsewhere, students learn (and forget) lots of knowledge, have only limited experience with the application of knowledge and are ignorant of the clash between codified and practical knowledge. Consequently, the majority of our universities are disavowing their main goal, the development of ‘readiness for society’. It is this verdict that justifies a revolution in higher education.

  • 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

  • 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.

  • “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 effects of growing up in poverty, particularly for children raised in socially isolated, economically depressed urban areas, warrants greater concern, especially given that one out of every three Black children is raised in a poor household.(20) Here the evidence is clear that the risks faced by children, particularly African American males, in terms of health, welfare, and education, are substantially greater.(21) A recent longitudinal study on the development of children whose mothers used drugs (particularly crack cocaine) during pregnancy found that when compared to children residing in similar neighborhoods from similar socio-economic backgrounds, the children in the sample showed no greater evidence of long term negative effects. This is not because the incidence of physical and cognitive problems among the sample was not high, but because it was equally high for the control group. The stunned researchers, who fully expected to observe noticeable differences between the two groups, were compelled to conclude that the harmful effects of living within an impoverished inner-city environment outweighed the damage inflicted by early exposure to drugs.(22)

    Educational Origami is a blog , and a wiki, about the integration of ICT (Information and Communication Technologies) into the classroom, this is one of the largest challenges that I feel we as teachers face. It's about 21st Century Learning and 21st Century Teaching. Marc Prensky coined the now popular and famous phrase "Digital natives and digital immigrants" in his two papers by the same name. Ian Jukes talks about Digital Children. The world is not as simple as saying teachers are digital immigrants and students digital natives. In fact people fit into both camps. We know that experience, like using a computer, will change the structure of our brain, This is a concept called Neuroplasticity. We also know that, the more intense the experience, the more profound the change. Our students, who often have a greater exposure to technology, are likely to be more neurologically adapted, but adults can as easily be "Digital Natives". I made this wiki on request from Miguel Guhlin after I blogged about matching ICT tools to traditional classroom practice and Bloom's Taxonomy.The wiki has grown a little since then.

Moreover, those that do participate in politics and activism online do so in shallow ways, the so-called "slacktivism." But recent findings from a longitudinal study of high school-age students challenges these notions, suggesting that youth who pursue their interests online are more likely to be engaged in civic issues."

  • Now consider that, according to the American Association of Community Colleges, about half of all freshmen and sophomores are enrolled at the nation's 1,300 two-year colleges, and many of those students transfer to four-year institutions. For a large percentage of people who earn bachelor's degrees, then, the liberal-arts portion of their education was acquired at a two-year college. Next, factor in all of the community-college students who enter the work force after earning two-year degrees or certificates, and whose only exposure to the liberal arts occurred in whatever core courses their programs required. The conclusion becomes obvious: Two-year colleges are among the country's leading providers of liberal-arts education, although they seldom get credit for that role.
  • Employers rank communication and analytical skills among the most important attributes they seek in new hires, according to the National Association of Colleges and Employers. Perhaps those of us who teach those very skills at community colleges should embrace the integral role we play in preparing the nation's workers rather than rejecting the idea of work-force development as somehow beneath us.
  • More important, this new perspective could have a positive effect on student success. If we come to see ourselves as preparing students not just for transfer but ultimately for the work force, students may be more likely to understand the relevance of the skills that we teach them and better able to use those skills for some purpose other than just getting a passing grade.
  • ...5 more annotations...
  • Require lots of writing. As the management guru Peter Drucker argued, communication is the one skill required of all professionals, regardless of field. "As soon as you take one step up the career ladder," he said, "your effectiveness depends on your ability to communicate your thoughts in writing and in speaking."
  • Clearly, one of the best things we can do for students is to require them to write—a lot.
  • Focus on critical thinking. A common complaint of employers, as reflected in the NACE survey, is that many workers have difficulty thinking for themselves. They may be thoroughly trained, having mastered all of the concepts in the textbooks, but, inevitably, situations arise that weren't covered in the books. When that happens, the ability to think critically, independently, and creatively becomes indispensable.
  • Bring the real world into the classroom. Another strategy we can adopt, if we want our courses to be more relevant, is to make our class discussions, case studies, experiments, and assignments as real-world-based as possible. For example, in my composition courses, I not only allow students to choose their own essay topics, but I also encourage them to write about issues related to their prospective majors. I also assign reading (in addition to the old textbook standbys) from newspapers, popular magazines, even the Internet.
  • Make the connection. Take advantage of every opportunity to connect what students are doing in class with what they will be doing some day as employees. My students hear the term "the real world" so much that, by the middle of the term, they're starting to roll their eyes. But it's important for them to understand that the work we're doing now in class isn't just a series of meaningless exercises, another set of hoops for them to jump through on their way to a degree. They're going to have to do these things for real one day—describe processes, do research to find solutions, draw comparisons—and my course may be the last time anyone ever actually teaches them how.

As with any instructional design, the teacher determines the pace at which the students best assimilate each new learning tool. For this particular project, a new tool was introduced each day over two weeks. Once the construction process was complete, there were a number of personal web page aggregators that could have been selected to bring everything together in one place. Options at the time included iGoogle, PageFlakes, NetVibes, and Symbaloo. These sites offer a means to compile or pull together content from a variety of web applications. A web widget or gadget is a bit of code that is executed within the personal web page to pull up external content from other sites. The students in this case designed the personal web page using the gadgets needed in the format that best met their learning goals. Figure 3 is an instructor example of a personal webpage that includes the reader, email, personal blog, note taking program, and social bookmarks on one page. The personal learning environment can take the place of a traditional textbook, though does not preclude the student from using a textbook or accessing one or more numerous open source texts that may be available for the research topic. The goal is to access content from many sources to effectively meet the learning objectives. The next challenge is to determine whether those objectives have been met.

Content gathering/ digital notebook Evernote http://evernote.com/ Set up account Use Evernote to take notes on all content collected via other tools Content synthesis Wikispaces http://www.wikispaces.com Post final project on personal page of class wiki The process and tools are overwhelming to students if presented all at once. As with any instructional design, the teacher determines the pace at which the students best assimilate each new learning tool. For this particular project, a new tool was introduced each day over two weeks. Once the construction process was complete, there were a number of personal web page aggregators that could have been selected to bring everything together in one place. Options at the time included iGoogle, PageFlakes, NetVibes, and Symbaloo. These sites offer a means to compile or pull together content from a variety of web applications. A web widget or gadget is a bit of code that is executed within the personal web page to pull up external content from other sites. The students in this case designed the personal web page using the gadgets needed in the format that best met their learning goals. Figure 3 is an instructor example of a personal webpage that includes the reader, email, personal blog, note taking program, and social bookmarks on one page.
  • The personal learning environment can take the place of a traditional textbook, though does not preclude the student from using a textbook or accessing one or more numerous open source texts that may be available for the research topic. The goal is to access content from many sources to effectively meet the learning objectives. The next challenge is to determine whether those objectives have been met.

  • AssessmentThere were four components of the assessment process for this test case of the Networked Student Model: (1) Ongoing performance assessment in the form of weekly assignments to facilitate the construction and maintenance of the personal learning environment, (2) rubric-based assessment of the personal learning environment at the end of the project, (3) written essay, and (4) multimedia synthesis of topic content. Points were earned for meeting the following requirements: Identify ten reliable resources and post to social bookmarking account. At least three new resources should be added each week. Subscribe and respond to at least 3 new blogs each week. Follow these blogs and news alerts using the reader. Subscribe to and listen to at least two podcasts (if available). Respectfully contact and request a video conference from a subject matter expert recognised in the field. Maintain daily notes and highlight resources as needed in digital notebook. Post at least a one-paragraph reflection in personal blog each day. At the end of the project, the personal learning environment was assessed with a rubric that encompassed each of the items listed above. The student's ability to synthesise the research was further evaluated with a reflective essay. Writing shapes thinking (Langer & Applebee, 1987), and the essay requirement was one more avenue through which the students demonstrated higher order learning. The personal blog provided an opportunity for regular reflection during the course of the project. The essay was the culmination of the reflections along with a thoughtful synthesis of the learning experience. Students were instructed to articulate what was learned about the selected topic and why others should care or be concerned. The essay provided an overview of everything learned about the contemporary issue. It was well organised, detailed, and long enough to serve as a resource for others who wished to learn from the work. As part of a final exam, the students were required to access the final projects of their classmates and reflect on what they learned from this exposure. The purpose of this activity was to give the students an additional opportunity to share and learn from each other. Creativity is considered a key 21st century skill (Partnership for 21st Century Skills, 2009). A number of emerging web applications support the academic creative process. Students in this project used web tools to combine text, video, audio, and photographs to teach the research topics to others. The final multimedia project was posted or embedded on the student's personal wiki page. Analysis and assessment of student work was facilitated by the very technologies in use by the students. In order to follow their progress, the teacher simply subscribed to student social bookmarking accounts, readers, and blogs. Clicking through daily contributions was relatively quick and efficient.
