Managerial Decisions

Managerial Decision Making



A group of children were playing near two railway tracks, one still in use while the other disused. Only one child played on the disused track, the rest on the operational track.

The train is coming, and you are just beside the track interchange. You can make the train change its course to the disused track and save most of the kids. However, that would also mean the lone child playing by the disused track would be sacrificed. Or would you rather let the train go its way?

Let's take a pause to think what kind of decision we could make................

Most people might choose to divert the course of the train, and sacrifice only one child. You might think the same way, I guess. Exactly, I thought the same way initially because to save most of the children at the expense of only one child was rational decision most people would make, morally and emotionally. But, have you ever thought that the child choosing to play on the disused track had in fact made the right decision to play at a safe place?

Nevertheless, he had to be sacrificed because of his ignorant friends who chose to play where the danger was. This kind of dilemma happens around us everyday. In the office, community, in politics and especially in a democratic society, the minority is often sacrificed for the interest of the majority, no matter how foolish or ignorant the majority are, and how farsighted and knowledgeable the minority are.. The child who chose not to play with the rest on the operational track was sidelined. And in the case he was sacrificed, no one would shed a tear for him.

The great critic Leo Velski Julian who told the story said he would not try to change the course of the train because he believed that the kids playing on the operational track should have known very well that track was still in use, and that they should have run away if they heard the train's sirens. If the train was diverted, that lone child would definitely die because he never thought the train could come over to that track! Moreover, that track was not in use probably because it was not safe. If the train was diverted to the track, we could put the lives of all passengers on board at stake! And in your attempt to save a few kids by sacrificing one child, you might end up sacrificing hundreds of people to save these few kids.

While we are all aware that life is full of tough decisions that need to be made, we may not realize that hasty decisions may not always be the right one.

Satellites Unlock Secret to Northern India's Vanishing Water

Satellites Unlock Secret to Northern India's Vanishing Water

WASHINGTON -- Using NASA satellite data, scientists have found that groundwater levels in northern India have been declining by as much as one foot per year over the past decade. Researchers concluded the loss is almost entirely due to human activity.

More than 26 cubic miles of groundwater disappeared from aquifers in areas of Haryana, Punjab, Rajasthan and the nation's capitol territory of Delhi, between 2002 and 2008. This is enough water to fill Lake Mead, the largest manmade reservoir in the United States, three times.

A team of hydrologists led by Matt Rodell of NASA's Goddard Space Flight Center in Greenbelt, Md., found that northern India's underground water supply is being pumped and consumed by human activities, such as irrigating cropland, and is draining aquifers faster than natural processes can replenish them. The results of this research were published today in Nature.

The finding is based on data from NASA's Gravity Recovery and Climate Experiment (GRACE), a pair of satellites that sense changes in Earth's gravity field and associated mass distribution, including water masses stored above or below Earth's surface. As the twin satellites orbit 300 miles above Earth's surface, their positions change relative to each other in response to variations in the pull of gravity.

Changes in underground water masses affect gravity enough to provide a signal that can be measured by the GRACE spacecraft. After accounting for other mass variations, such changes in gravity are translated into an equivalent change in water.

"Using GRACE satellite observations, we can observe and monitor water storage changes in critical areas of the world, from one month to the next, without leaving our desks," said study co-author Isabella Velicogna of NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the University of California, Irvine.

Groundwater comes from the natural percolation of precipitation and other surface waters down through Earth’s soil and rock, accumulating in cavities and layers of porous rock, gravel, sand or clay. Groundwater levels respond slowly to changes in weather and can take months or years to replenish once pumped for irrigation or other uses.

Data provided by India's Ministry of Water Resources to the NASA-funded researchers suggested groundwater use across India was exceeding natural replenishment, but the regional rate of depletion was unknown. Rodell and colleagues analyzed six years of monthly GRACE data for northern India to produce a time series of water storage changes beneath the land surface.

"We don't know the absolute volume of water in the northern Indian aquifers, but GRACE provides strong evidence that current rates of water extraction are not sustainable," said Rodell. "The region has become dependent on irrigation to maximize agricultural productivity. If measures are not taken to ensure sustainable groundwater usage, the consequences for the 114 million residents of the region may include a collapse of agricultural output and severe shortages of potable water."

Researchers examined data and models of soil moisture, lake and reservoir storage, vegetation and glaciers in the nearby Himalayas in order to confirm that the apparent groundwater trend was real. The loss is particularly alarming because it occurred when there were no unusual trends in rainfall. In fact, rainfall was slightly above normal for the period. The only influence they couldn't rule out was human.

"For the first time, we can observe water use on land with no additional ground-based data collection," said co-author James Famiglietti of the University of California, Irvine. "This is critical because in many developing countries, where hydrological data are both sparse and hard to access, space-based methods provide perhaps the only opportunity to assess changes in fresh water availability across large regions."

GRACE is a partnership between NASA and the German Aerospace Center, DLR. The University of Texas Center for Space Research in Austin has overall GRACE mission responsibility. GRACE was launched in 2002.

Twitter Tweety Killed, Facebook ripped and the Social Network Drowned

The two biggies of the Social Network seemed to cripple as both Twitter and Facebook faced outage of services which ultimately came up to be a DDoS attack from an unidentified source. The attack was carried out at some 10 AM Eastern Time. This attack also followed on other sites such as LiveJournal and recently Youtube is reported to have the same slowdown. Although Youtube has not stated any of its service down.

As on Twitter Status Blog, Twitter reported the problem while tweeters waited long to their favorite social network. The outage has been reported to be the longest stretching whole 2 hours which in Online terms is quite a long time!

The blogosphere and other social networks were filled with disappointed Tweeters reaching out for alternatives and with cries for the outage of the service.

Twitter then reported to be "defending against a Distributed Denial-of-Service (DDoS) attack" that was causing the outage.

After it was over with Twitter came a news about Facebook facing the same problem. Worldwide Facebook returned Network errors with its service increasing the disappointment in people. After all we love to be socially connected of which facebook is an indispensable part.

After the Attack was succesfully defended, Facebook Officials stated the same outage to be a DDoS of which the source is still to be tracked.

But what caused this chaos in the Social Network world? Some blogs have reported the source of attack to be related to the Georgia Russia Crisis and that the attack was organized to silence one man reported to be "cyxymu" as on Twitter.

In an interview, Facebook's chief security officer Max Kelly told CNET.com, “It was a simultaneous attack across a number of properties targeting him to keep his voice from being heard. We’re actively investigating the source of the attacks and we hope to be able to find out the individuals involved in the back end and to take action against them if we can.”

Google is quoted as saying, “We are aware that a handful of non-Google sites were impacted by a DOS attack this morning, and are in contact with some affected companies to help investigate this attack. Google systems prevented substantive impact to our services.”

The claims back up earlier reports in the New York Times that Thursday’s attack was sparked by the conflict between Russia and Georgia. The aim was to take down Cyxymu’s accounts, particularly the LiveJournal blog where he posted about the crisis. While Google’s sites held up to the barrage, Twitter and LiveJournal proved less robust.

While DDoS attacks are notoriously hard to defend against, it’s clear that Twitter was far less equipped to cope with such an attack: no doubt they’ll be taking a closer look at how such issues could be handled in the future.

Another blog post also reported a leading security expert as stating that this attack was not a normal DDoS that we usually see with a botnet and malware and trojan infected computers supporting the attack. Rather this was an organized attack.
he security expert spoke with The New York Times and gave his assessment of the situation:

Bill Woodcock, a research director of the Packet Clearing House, a nonprofit technical organization that tracks Internet traffic, said Thursday’s attack was an extension of the conflict between Russia and Georgia. It was not clear who initiated the attack, he said, but likely “one side put up propaganda, the other side figured this out and is attacking them.”

Instead of using a botnet, or a network of thousands of malware-infected personal computers to flood a site with traffic, Mr. Woodcock said this particular attack consisted of a wave of spam e-mail messages, which began infiltrating Twitter and other sites at 10:25 a.m. Eastern time. “It’s a vast increase in traffic that creates the denial-of-service,” he said.

YouTube and LiveJournal were also affected, Mr. Woodcock said, although “Twitter was definitely hit the hardest.” YouTube said it had not noticed any problems with its service.

Reference from: Mashable

Whatever happened to the Social World has been a sort of security lessons to this network and if the attack was related to cyber warfare, then we could be seeing a lot more of this. Still, it’s tough to understand how these social media sites would be of any strategic value to either Russia or Georgia. Today’s events are certainly getting even more complicated, though.

August : The Month of the Meteors

Source: NASA News Service

Yes, it is true. According to NASA, August is the month of Meteors. This August is the Perseid Meteor Shower.

We'll get to see some Perseids all month long -- before and after midnight -- but the real fireworks will be going on the 12th of August, 2009 between (yawn!) 2 and 4 am (California) and 9-11 AM (GMT) while Indian people might be disappointed with the time for India corresponding to this will be 2:30-4:30 PM. Still, people can try to see it after dark on the 11th or 12th of August

Metoer showers are best seen in the hours after midnight. That's when Earth is facing the d direction in which the dust particles are colliding with our atmosphere.

As a bonus, two more planets will show up, one Venus as the brighter one and the other Mars as the red little faint one. NASA also says that even Neptune might be visible if you have a telescope.

If you've ever wondered about this cosmic firework, what makes up these beauties? Well, according to Jane Houston Jones of NASA's Jet Propulsion Lab, Meteor showers are just the debris of a passing comet or sometimes the debris from a fragmented asteroid.

When a comet nears the sun, its icy surface heats up. This causes clouds of gas, dirt and dust to be releases, forming a tail of debris that can stretch for millions of miles.

As Earth passes near the dusty tail, some of the dust particles hit our atmosphere. They burn up and create the celestial firworks we see.

NASA monitors these meteor showers to safeguard any launching or orbiting spacecraft.

The best part is You don't need any telescopes or binoculars to view these showers. Infact, these are better seen with naked eyes!

So, go out on your roofs and you won't be disapponted for stayin' up so late!
