For decades, Ritalin and similar stimulants have reigned over other treatments for attention deficit hyperactivity disorder, also known as ADHD or ADD. The meds are seemingly tried and true, with numerous studies backing their effectiveness.

However, the latest results from the Multimodal Treatment Study of Children with ADHD, the largest investigation of the benefits of medication against behavioral therapy, found that stimulants' effects wane over time. In addition, the study found that more than 60 percent of the children on stimulants stopped taking the medication within eight years. What's more, the medications used in the study might have stunted participants' growth, researchers concluded. The vast majority of kids respond positively to one or more of the approved medications for ADHD, according to Mina Dulcan, head of child and adolescent psychiatry at Children's Memorial Hospital in Chicago.

I’ve since had zero pain in my hands when typing for many hours straight, I’ve been able to type faster, and I make fewer mistakes while typing. A few months ago, I decided to try the biphasic sleep cycle. It worked as advertised, allowing me to get better sleep and need less of it. I used to sleep for 9 - 10 hours each day, and now I need just 6 - 7.5 to stay just as sprightly, if not more.

A few weeks ago, after these successful life hacks, my friend told me about the eccentric work cycle that he follows. “You might think it’s crazy and stupid, but it works for me,” he said. Immediately, I thought, ‘That won’t work for me.’ ‘Hmmm. You can probably tell by now where this story is going. Abracadabra It works. While working on a software project, I would get stuck on a bug and spend hours trying to figure out what went wrong, addicted to the quest and unable to stop, even when I run out of ideas on what else to try.

Revealing the trick. Have you guys noticed that if you film something and call it reality TV, you can do experiments on humans that would never be approved by any review board? : AskReddit.

How does the social media giant decide who and what to put in your feed? Tom Weber conducts a one-month experiment to break the algorithm, discovering 10 of Facebook’s biggest secrets. The more digital our daily lives become, the more perplexing the questions seem. Will the growth of social media destroy our notions of privacy? Is democracy helped or harmed by the cacophony of opinions online? And perhaps most confounding: Why does that guy I barely know from the 10th grade keep showing up in my Facebook feed?

If you've ever spent time on Facebook, you've probably pondered that last one. The social-networking giant promises to keep us connected with our friends in exchange for pumping a steady diet of advertising at us—but the algorithms Facebook uses to decide what news to pass along can seem capricious or altogether impenetrable. The Daily Beast’s one-month experiment into Facebook’s news feed yielded the following discoveries: • Facebook Privacy: What Really Happens to Users' Data 1. 2.

Cleaning Up Audio Files with Audacity - Geeks. The Compressor dialog box looks intimidating, but once you get going it is fairly easy to use. Focus on the Threshold setting. The threshold is the maximum amount of volume that the Compressor will tolerate. The threshold is measured in decibels (db). Any bit of audio that is louder than the threshold has its volume reduced. You should set a threshold somewhere between the loudest and softest parts of your audio. Next, look at the Ratio setting. Leave the Attack Time setting as it is.

Also, leave the Apply Gain after compressing option checked. Click the Preview button to test whether or not you chose the right settings. As with the noise removal process, test the compression by playing the appropriate section of the file. Gravity. JavaStat -- 2-way Contingency Table Analysis. 2-way Contingency Table Analysis Revised: 07/23/2013 -- added NNM -- the Number Needed to Mis-diagnose (thanks to Farrokh Habibzadeh) This page computes various statistics from a 2-by-2 table. It will calculate the Yates-corrected chi-square, the Mantel-Haenszel chi-square, the Fisher Exact Test, and other indices relevant to various special kinds of 2-by-2 tables: analysis of risk factors for unfavorable outcomes (odds ratio, relative risk, difference in proportions, absolute and relative reduction in risk, number needed to treat) analysis of the effectiveness of a diagnostic criterion for some condition (sensitivity, specificity, pos & neg predictive values, pos & neg likelihood ratios, diagnostic and error odds ratios) measures of inter-rater reliability (% correct or consistent, mis-classification rate, kappa, Forbes' NMI) other measures of association (contingency coefficient, Cramer's phi coefficient, Yule's Q) Enter numbers into the four cells below.
