Submission + - India's Engineering Grads Cannot Solve Simple Math Problems (intoday.in) 7

chiguy writes: MIT alumnus Varun Aggarwal and IIT-Delhi graduate Himanshu Aggarwal released a study suggesting that 30% of Indian engineering graduates can't solve simple math problems. As reported in India Today:

"A bag is full of 20 bananas and no other fruit. Rajeev draws a fruit from the bag. What is the probability that he will draw a banana?

An embarrassing 30 per cent of the country's engineers cannot solve a problem as simple as the one above, a study has found. Their ineptitude, however, is not limited to just sums of probability.

It's worse as over one-third engineers do not possess mathematical skills needed in day-to-day life for doing simple transactions, counting and arranging. In other words, they have a weak understanding of concepts as elementary as decimals, powers, operations, ratio, fractions and the ability to apply these concepts to real-world problems."

Is this surprising? How does this compare to American/Western countries?

Also, I'm curious to know which headaches you're running into with Windows 7, because I can't think of any offhand. XP? sure. Vista? Of course. 7? nothing comes to mind.

OK, I have one, but for me, it's a doozy. Searching for contents of a file doesn't work the way I want by default. Mainly because if you're searching in a non-indexed directory, there's no option to search the contents of a file. Even if you're in an indexed directory, only files with known AND selected types are searched. And if you want to search PDFs, you have to install one of two 3rd party iFilters (1 of which costs $600 if you want to search PDFs on your Win Server). WTF? No PDF search in Win 7? Even Vista allowed you to search ANY file. Changing the settings doesn't make it work even as well as Vista. Some people have VMs running Vista just so they can do better searches. I use a 3rd party app to search for contents of a file in Win 7, which is beyond irritating.

And MS hasn't addressed or fixed the search UI since people started complaining about it in 2009:

Other than that, I actually like Win 7.

"Back of the bus", in the US, is a reference to a method of racial discrimination in the US where blacks were forced to move to the farthest seats away from where fares were paid. This is different from the younger experience of wanting to be in the back of a school bus farther away from surveillance by authority (bus driver).

From Wiki re Rosa Parks: http://en.wikipedia.org/wiki/Rosa_Parks

In Montgomery, the first four rows of bus seats were reserved for white people. Buses had "colored" sections for black people—who made up more than 75% of the bus system's riders—generally in the rear of the bus. These sections were not fixed in size but were determined by the placement of a movable sign. Black people could sit in the middle rows, until the white section was full. Then they had to move to seats in the rear, stand, or, if there was no room, leave the bus. Black people were not allowed to sit across the aisle from white people. The driver also could move the "colored" section sign, or remove it altogether. If white people were already sitting in the front, black people could board to pay the fare, but then had to disembark and reenter through the rear door. Sometimes, the bus departed before the black customers who had paid could make it to the back entrance.

In 1900, Montgomery had passed a city ordinance for the purpose of segregating passengers by race. Conductors were given the power to assign seats to accomplish that purpose; however, no passengers would be required to move or give up their seat and stand if the bus was crowded and no other seats were available. Over time and by custom, however, Montgomery bus drivers had adopted the practice of requiring black riders to move whenever there were no white only seats left.

This is sort of how it works.

S00–T98 Injury, poisoning and certain other consequences of external causes
S90–S99 ankle and foot
S92 Fracture of foot, except ankle
S92.4 Fracture of great toe

For unusual cases, it'd be something like: S92.9 Fracture of foot, unspecified
in which case a progress note would have to be sent to the insurer.

Statements like this make it clear that people don't understand the nature of the insurance industry.

No, health insurance is just like any other insurance, such as car insurance.

1) Insurers collect premiums. This is their revenue.
2) Insurers spend money on running their business. This is overhead.
3) Insurers pay out money for covered events. This is claims paid.
4) What's left over is profit.

Every transaction (claim) costs insurers money. Be it healthcare, auto, or life.

This poster does not understand the nature of any insurance industry, much less American health insurance.
If they can deny a claim, then they can keep the money that they collected through premiums as profit.

I know it sounds counter intuitive but insurance companies make their money by skimming a percentage off of every transaction

It's counter-intuitive because it's not true.

Having been in healthcare for a while now, I have no idea what this poster is talking about.

Considering that insurance billing currently has nothing to do with injury coding, and this is merely the next iteration of it, I think your paranoia is misplaced.

WTF?

CMS1500 billing forms require you specify both an ICD-9 diagnosis code (that would be the "injury code" you're denying) and a CPT procedure code (that would be what you did for the injury you coded).

So you're obviously pulling s* out of your a*

Neither the government (Medicaid, Medicare) nor private insurance companies currently base payment on injury codes, so I'm not sure why you think they will begin to now.

Because the current ICD-9 codes do not have detailed causation. Here's what a billing looks like:

Fracture of lower limb (820–829)

        (820) Fracture of neck of femur
        (821) Fracture of other and unspecified parts of femur
        (822) Fracture of patella
        (823) Fracture of tibia and fibula
        (824) Fracture of ankle
        (825) Fracture of one or more tarsal and metatarsal bones
        (826) Fracture of one or more phalanges of foot
        (827) Other, multiple, and ill-defined fractures of lower limb
        (828) Multiple fractures involving both lower limbs, lower with upper limb, and lower limb(s) with rib(s) and sternum
        (829) Fracture of unspecified bones

The injury is indicated. The cause is not.

But if you give insurance companies more information about the circumstances of injury, as you do in ICD-10, then you allow insurance companies the information to more finely deny coverage. So your insurance policies now state they will cover injuries except for those that occur on a list of dangerous activities.

And in case you think they wouldn't micromanage like that, a friend of mine was able to get insurance coverage but ANY injury to his left knee, which had an ACL repair done 20 years ago, would not be covered.

In an era where both public and private insurance is trying to save money, more reasons to deny coverage is sure to come out of this.

The 25 or so other countries who use these codes already have not yet imploded.

When doctors are salaried and are paid for the extra time they spend pushing papers, as they are in other western countries, then it's no big deal. The government-paid doctors just see fewer patients and make the same amount of money.

In the US, however, this is an unfunded mandate. Doctors spend an extra few minutes looking up more detailed codes per patient, times the number of doctors, and you can see the economic impact.

Sure its not good but it should still work.

Plants and animals generally don't "still work" at -30C. Only very specialized plants and animals do.

If you purchase a pack of alligators to pull your Iditarod sled across Alaska, not only are you operating them outside their design specs, the clerk has every right to deny you a warranty replacement when yours dies.

You should use specialized, extra-insulated alligators. But they aren't mass produced, so they cost more.
