The Not-So-Hidden Cause Behind the A.D.H.D. Epidemic - NYTimes.com - 58 views

  •  
    Between the fall of 2011 and the spring of 2012, people across the United States suddenly found themselves unable to get their hands on A.D.H.D. medication. Low-dose generics were particularly in short supply. There were several factors contributing to the shortage, but the main cause was that supply was suddenly being outpaced by demand.

Teaching about the "stress bucket" in schools by @sam_oldale - 19 views

  •  
    A few months ago I went on a Mental Health First Aid in schools course. We learnt about the stress bucket. So it goes like this. Basically we all have a stress bucket. If it gets too full as the stresses of life flow in to it, it will over fill and over flow and we will begin to feel overwhelmed. Coping strategies are like a tap on the bucket and should be used to allow some of the stress to be released and will prevent us from becoming overwhelmed. If our stress bucket gets too full we can suffer from mental ill health. Some life events such as bereavement, illness etc. can cause our buckets to overflow quite quickly but sometimes small life stressors can build and accumulate also causing our buckets to fill...

Teens, Sleep and School - 1 views

  • Research shows that teens need eight to nine hours of sleep at night, as compared with eight hours needed for adults. However, they are not getting enough sleep.
  • Tests by a professor at Oxford suggest that "students perform better in the afternoon, because their body clock is programmed about two hours later, possibly for hormonal reasons."
  • One solution is for parents to impose earlier bedtimes on their teenagers. A recent study found that "Teens whose parents pack them off to bed at 10 p.m. are less apt to become depressed or have suicidal thoughts than their peers who stay up much later."

  • parents can strive to get their teens less wired at night. This can be achieved by discouraging them from drinking caffeine past 12 noon, and by keeping TVs, computers, and especially cell phones out of their room at night.

    "Research has shown that teenagers don't get enough sleep at night and go to school tired. Some experts believe the cause is biological. Others believe that teenagers stay up late because of adolescent distractions. Early high school start times can also contribute to teens' tiredness. This article will explore possible causes and solutions to this problem."

An Introduction to Inquiry-Based Learning - 122 views

  •  
    "What kinds of questions make for good inquiry-based projects? As we said, they must first be questions that the kids truly care about because they come up with them themselves. In addition, good questions share the following characteristics: The questions must be answerable. "What is the poem 'Dream Deferred' based on?" is answerable. "Why did Langston Hughes write it?" may be answerable if such information exists, or if the students have some relevant and defensible opinions. "Why did he choose this particular word in line six?" is not answerable because the only person likely to know such a specific answer is Hughes himself, now deceased. The answer cannot be a simple fact. "In what year was Lincoln killed?" doesn't make for a very compelling project because you can just look it up in any number of books or Web sites. "What factors caused the assassination attempt?" might be a good project because it will require research, interpretation, and analysis. The answer can't already be known. "What is hip-hop music?" is a bit too straightforward and the kids are not likely to learn much more than they know already. "What musical styles does hip-hop draw from and how?" offers more opportunity for exploration. The questions must have some objective basis for an answer. "Why is the sky blue?" can be answered through research. "Why did God make the sky blue?" cannot because it is a faith-based question. Both are meaningful, valid, real questions, but the latter isn't appropriate for an inquiry-based project. "What have people said about why God made the sky blue?" might be appropriate. Likewise, "Why did the dinosaurs become extinct?" is ultimately unanswerable in that form because no humans were around to know for sure, but "What do scientists believe was the reason for their extinction?" or "What does the evidence suggest about the cause?" will work. Questions based on value judgments don't work for similar reasons. You can't objectively answer "Is Hamle

  • 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
  • ...5 more annotations...
  • 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.

Causes of Texas Revolution - 9 views

  • "Many a Cause, Many a Conflict: The Texas Revolution" Introduction Volumes sufficient to fill multiple warehouses have been written about the Texas Revolution of 1836 in the century and a half since it culminated in the seventeen minute Battle of San Jacinto. Few topics have inspired such polarized feelings. Many blame Mexico's loss of her northernmost regions on a conscious premeditated conspiracy of Anglo-Americans in the United States to steal Texas by whatever means possible. This conspiracy, supported by the American government in Washington, D.C., first bore fruit in 1835-36 with the Texas Revolution and culminated ten years later with the Mexican War which resulted in the loss of the present-day states of New Mexico, Colorado, Nevada, Utah, Arizona, and California. At the other end of the continuum are those who blame the Mexican people for the misrule of Texas and the ruthless dictatorship of Santa Anna for provoking a fully justified rebellion by Anglo-Americans and Tejanos. While such extreme positions are far too simplistic to explain the events of 1835-36, they continue to be voiced today - a century and a half after the fact.

Hate Speech and Hate Crime | Advocacy, Legislation & Issues - 3 views

  • There is no legal definition of "hate speech" under U.S. law, just as there is no legal definition for evil ideas, rudeness, unpatriotic speech, or any other kind of speech that people might condemn. Generally, however, hate speech is any form of expression through which speakers intend to vilify, humiliate, or incite hatred against a group or a class of persons on the basis of race, religion, skin color sexual identity, gender identity, ethnicity, disability, or national origin. 1 In the United States, hate speech is protected by the First Amendment. Courts extend this protection on the grounds that the First Amendment requires the government to strictly protect robust debate on matters of public concern even when such debate devolves into distasteful, offensive, or hateful speech that causes others to feel grief, anger, or fear. (The Supreme Court's decision in Snyder v. Phelps provides an example of this legal reasoning.) Under current First Amendment jurisprudence, hate speech can only be criminalized when it directly incites imminent criminal activity or consists of specific threats of violence targeted against a person or group. Hate Crime For the purposes of collecting statistics, the FBI has defined a hate crime as a “criminal offense against a person or property motivated in whole or in part by an offender’s bias against a race, religion, disability, sexual orientation, ethnicity, gender, or gender identity,” including skin color and national origin.  Hate crimes are overt acts that can include acts of violence against persons or property, violation or deprivation of civil rights, certain "true threats," or acts of intimidation, or conspiracy to commit these crimes. The Supreme Court has upheld laws that either criminalize these acts or impose a harsher punishment when it can be proven that the defendant targeted the victim because of the victim's race, ethnicity, identity, or beliefs.  A hate crime is more than than offensive speech or conduct; it is specific criminal behavior that ranges from property crimes like vandalism and arson to acts of intimidation, assault, and murder.  Victims of hate crimes can include institutions, religious organizations and government entities as well as individuals.

Why do so many oil spills happen? - CSMonitor.com - 0 views

    • Jeff Woodcock
       
      hard part
  •  
    "n brief, because there are a lot of tricky steps to get oil from inside the Earth to inside, say, your gas tank. Oil spills can be caused by the accidental or intentional release of any form of petroleum during any point in the oil production process, from drilling, refining, or storing to transporting. Oil can be spilled when a pipeline breaks, ships collide or are grounded (as happened earlier this month along the Great Barrier Reef), underground storage tanks leak, or in the current case, when an oil rig explodes or is damaged. IN PICTURES: Big Environmental Disasters Some oil was spilled when the Deepwater Horizon rig first burst into flames on April 20 in the Gulf, injuring crew members and sending a billowing plume of black smoke into the sky that could be seen by satellite. The oil rig, located about 51 miles (82 kilometers) southeast of Venice, La., then sank into the Gulf waters Thursday morning, creating concern that more oil could spill. Oil spills can also happen naturally: Oil is released into the ocean from natural oil seeps on the seafloor. The best known such seep is Coal Oil Point along the California coast where an estimated 2,000 to 3,000 gallons (7,570 to 11,400 liters) of crude oil is released each day."

  • In a move to link pay more closely with performance, the main pay scale for classroom teachers will be abolished, handing sweeping new powers to heads to decide pay levels.
  • the move would “effectively demolish the national pay framework”, and cause “inconsistency and unfairness” for teachers
  • changes would allow schools greater power to “reward their best teachers”.

12/21/12: Definitely Not the End of the World | Wired Science | Wired.com - 29 views

  • There is not a single iota of evidence that large-scale planetary alignments cause changes in geologic events – like earthquakes and eruptions – on Earth. The only celestial bodies that could play some role – and there is some evidence that suggest that they may, in minor ways – are the Sun and the Moon. This is due to their relative close proximity (especially the moon) and their mass. I’ve covered some of this in my discussion of why the so-called “Supermoons” are silly and play no role in increasing/decreasing geologic events. What about the alignment with the galactic center? The center of the galaxy must exert some force on the Earth (and solar system) or we wouldn’t be orbiting it. However, beyond that fact that alignments like this happen all the time, the force that the galactic center exerts on Earth is ~0.00006x that of the Moon on Earth and ~0.00000037x that of the Sun, doesn’t it seem a little ridiculous to claim that the galactic center can change anything on Earth if the Sun and the Moon cause little-to-no effect on geologic events?

Understanding understanding and its implications - The Learner's Way - 25 views

  •  
    There are terms within education that we use with reckless abandon and as a result cause great levels of confusion. Understanding is one such word and its usage and our 'understanding' of it can have a significant effect on the learning we plan, deliver and assess. With multiple definitions and its broad usage in curriculum documents, philosophies of teaching and learning and as an indicator of the quality or depth of student learning it is a word we should better understand.

The Value of Argument by @History__Girls - 23 views

    "Debating societies may seem to be the preserve of Oxbridge and private schools, but there is a place for debating in classrooms everywhere, argues Gemma Jones Debating societies may seem to be the preserve of Oxbridge and private schools, but there is a place for debating in classrooms everywhere. From 'Why William Won the Battle of Hastings' to 'causes of the First World War', history is a natural subject to use debates to deepen knowledge in lessons. However, across the curriculum there is scope to engage the pupils in a structured debate to challenge misconceptions, structure arguments and encourage independent study. Additionally, participating in debates can develop confidence and public speaking skills."
