Down With Math (Originals)

Down With Math (Originals) Yes, let me raise a simple question which may point to a partial answer. Why do students seeking certification of their competence in teaching, law, medicine, admission to virtually any higher education, get tested equally on mathematics as on everything else? SAT, GRE and LSAT and similar scores are based on a mandatory evaluation of math skills as as significant as tests of factual knowledge and intellectual skiils. Results in such math tests count for nearly as much as virtually everything else on the exams in which a person needs to perform well in order to snatch one of the glittering shares of the high pile of world money. But Homo sapiens acquired a portfolio of skills and interests which sustained our economic and social survival in an array of trying and often dire circumstances. We carry these in our heads still. They involve the ability to communicate with others, read their behavior, know how groups work, and track the links between ideas and succ

Too Much Sugar Is Bad, But Which Sugar Is Worse: Fructose Or Glucose?

Too Much Sugar Is Bad, But Which Sugar Is Worse: Fructose Or Glucose? ScienceDaily (Apr. 25, 2009) — In 2005, the average American consumed 64kg of added sugar, a sizeable proportion of which came through drinking soft drinks. Now, in a 10-week study, Peter Havel and colleagues, at the University of California at Davis, Davis, have provided evidence that human consumption of fructose-sweetened but not glucose-sweetened beverages can adversely affect both sensitivity to the hormone insulin and how the body handles fats, creating medical conditions that increase susceptibility to heart attack and stroke. In the study, overweight and obese individuals consumed glucose- or fructose-sweetened beverages that provided 25% of their energy requirements for 10 weeks. During this period, individuals in both groups put on about the same amount of weight, but only those consuming fructose-sweetened beverages exhibited an increase in intraabdominal fat. Further, only these individuals became less se

Obama's leap to Socialism- TheHill.com

TheHill.com President Obama showed his hand this week when The New York Times wrote that he is considering converting the stock the government owns in our country’s banks from preferred stock, which it now holds, to common stock. This seemingly insignificant change is momentous. It means that the federal government will control all of the major banks and financial institutions in the nation. It means socialism. The Times dutifully dressed up the Obama plan as a way to avoid asking Congress for more money for failing banks. But the implications of the proposal are obvious to anyone who cares to look. When the Troubled Asset Relief Program (TARP) intervention was first outlined by the Bush administration, it did not call for any transfer of stock, of any sort, to the government. The Democrats demanded, as a price for their support, that the taxpayers “get something back” for the money they were lending to the banks. House Republicans, wise to what was going on, rejected the administratio

Does Too Much Sun Cause Melanoma?

Does Too Much Sun Cause Melanoma? Two experts debate the issue in the British Medical Journal. Sam Shuster, a consultant dermatologist at Norfolk and Norwich University Hospital, says that sun exposure is the major cause of the common forms of skin cancer, which are all virtually benign, but not the rarer, truly malignant melanoma. Shuster says that the common skin cancers develop in pale, sun exposed skin and are less frequent in people who avoid the sun and use protection. In contrast, melanoma is related to ethnicity rather than pigmentation and in 75% of cases occurs on relatively unexposed sites, especially on the feet of Africans. Melanoma occurrence decreases with greater sun exposure and can be increased by sunscreens, while sun bed exposure has a small inconsistent effect. Therefore, he concludes, any causative effect of ultraviolet light on melanoma can only be minimal. There is good evidence that the reported increase in melanoma incidence is an artefact caused by the incorr

GetHerb:: Attention Deficit Disorder What is it

GetHerb:: Attention Deficit Disorder What is it Attention Deficit Disorder (ADD) and Attention Deficit Disorder with Hyperactivity (ADHD) occur as a result of neurological dysfunction in the prefrontal cortex of the brain. This is the newest part of our tri-brain system in evolutionary terms. It is the part of our brain that performs executive functions. The functions of this brain deal with 1) attention span, 2) perseverance, 3) judgment, 4) organization, 5) impulse control, 6) self-monitoring and supervision, 7) problem solving, 8) critical thinking, 9) forward thinking, 10) learning from experience, 11) ability to feel and express emotions, 12) interaction with the limbic system, and 13) empathy. Whenever there is a problem with this part of the brain, a number of skills that many human beings take for granted would not be available in any optimal way. The following are problems that develop when the prefrontal cortex is affected. 1) Short attention span, 2) distractibility, 3) lac

The Effects of Marijuana: Healthcare Medical Device

The Effects of Marijuana: Healthcare Medical Device Scientific studies released in mid-1997 indicate that people who smoke large amounts of marijuana may experience changes in their brain chemistry. These changes are similar to those seen in the brains of people who abuse addictive drugs such as heroin, cocaine, nicotine, and alcohol. All addictive drugs increase the amount of dopamine in the brain. Dopamine is a brain chemical responsible for causing feelings of reward. The new studies found (for the first time) that high doses of marijuana increased the levels of dopamine in the brain. Constant use of addictive drugs, however, can cause the brain to lose its ability to produce high levels of dopamine. When this happens, a drug user feels a greater need for the drug, or for even stronger drugs. Scientists believe this may occur with marijuana. Users of addictive drugs feel withdrawal symptoms (feeling anxious, edgy, and unable to cope) when they stop taking the drugs. It was previousl

For Some, Voice Mail Is Losing Its Allure - NYTimes.com

For Some, Voice Mail Is Losing Its Allure - NYTimes.com Research shows that people take longer to reply to voice messages than other types of communication. Data from uReach Technologies, which operates the voice messaging systems of Verizon Wireless and other cellphone carriers, shows that over 30 percent of voice messages linger unheard for three days or longer and that more than 20 percent of people with messages in their mailboxes “rarely even dial in” to check them, said Saul Einbinder, senior vice president for marketing and business development for uReach, in an e-mail message. By contrast, 91 percent of people under 30 respond to text messages within an hour, and they are four times more likely to respond to texts than to voice messages within minutes, according to a 2008 study for Sprint conducted by the Opinion Research Corporation. Even adults 30 and older are twice as likely to respond within minutes to a text than to a voice message, the study found. There are no definitiv

Paul Greenberg : The Entitled - Townhall.com

Paul Greenberg : The Entitled - Townhall.com "Academic Entitlement" syndrome It's no longer the coaches who appeal, wheedle, growl, grovel, or whatever it takes to raise a student's letter grade. It's the students themselves. Naturally enough, a team of academics has written a paper about this sad trend. ("Self-Entitled College Students: Contributions of Personality, Parenting and Motivational Factors"). The syndrome now has a name (Academic Entitlement) and an abbreviation (AE) -- just like Attention Deficit/Hyperactivity Disorder (ADHD). The four scholars who did this Pioneering Study trace the origins of AE to parental pressure, material rewards for good grades, competitiveness, and "achievement anxiety and extrinsic motivation." They conclude that AE is "most strongly related to exploitive attitudes towards others and moderately related to an overall sense of entitlement and to narcissism." At the risk of putting all that in plain
