3 results supplied by internet search engines is the limit by 80% of users and more than half of users checked out only one result, are the findings by researchers from the Penn. State School of Information Sciences and Technology (IST), 06-27-03. Typically, surfers visit only the first three results from a query, with one in five spending one minute or less on a linked web document. (Dr. Jansen and his co-author Professor Amanda Spink analysed more than 450,000 web queries submitted to the search engine in a 24-hour period. The research is said to provide sober reading for businesses using search engines to market themselves.

3 to 1 ratio of MG Taylor Corporation's Scan - Focus - Act concept:

1 of 3 small scan image Scan means just what you’d imagine; looking about for different options, or to gather information in a broad sort of way. Scan also implies a vantage point of some sort from which to view. The original meaning of the word means to climb or mount. In the Scan phase we build conceptual, mental models.
2 of 3 small focus symbol Focus implies choice. The majority of the opportunities presented by the scan are discarded in favor of only one or several, which are scrutinized and evaluated more rigorously. The models we build in Focus are more tangible expressions of the conceptual models we built in Scan. At length a decision is made and it's time to...
3 of 3 small act symbol Act! This is the opportunity to see whether the models will pan out as they become viable systems in their own right. If discipline and imagination have been brought to the two preceding stages, this stage should be successful.
1 of 1 small feed back symbol Feedback. The result of an experience is fed back as learning to the next iteration of the process. Feedback is termed positive if the desire is to grow the system, and called negative if homeostatic control, or goal-seeking is the object.

3 major types of Conserver Sociopolitical divisions/social views: Exchange ~ Authoritative ~ Coercive. Each label describes the dominant social power that would organize each society in the New World--exchange power, based on promises and bargaining; authoritative power based on (traditional) legitimacy; and coercion based on threats, (or the threat of threats). These types are shown as overlapping circles in the following illustration. Correlatively, the Conservers would rind three types of political proposals, which are represented by a triangle overlying the types of societies. Also shown are some mixed political types (policies)--fascist, conservative, welfare liberal, classical liberal, democratic socialist.

The political triangle defines a political space within which there is much ideological variation, with the extremes at the points of the triangle. For societies there would likewise be much variation from the pure types, with the mixtures of pure types given by the overlapping parts of the circles. These mixtures raise the possibility of some middle or compromise type of Sociopolitical system that might provide a consensual solution to the bargaining.

Three new moons orbiting the distant gas-giant planet Neptune have been found by researchers led by JJ Kavelaars of the National Research Council of Canada and Matthew Holman of the Harvard-Smithsonian Center for Astrophysics. This discovery boosts the number of known satellites of the gas giant to 11. They are the first moons to be discovered orbiting Neptune since the Voyager II fly-by in 1989, and the first discovered from a ground-based telescope since 1949.

3 types of Hair grafts used by Atlantis 2000 International:

Micro Micro Graft - Approximately 1 to 2 Hairs
Micro grafts are used mainly for recreating the front hairline. Going approximately ½ inch back from the new natural looking hairline. They are also used to imitate mother natures own creation.
Mini Mini Graft - Approximately 3 to 5 Hairs
A few mini grafts are placed throughout the new front hairline to give a natural appearance. Mini-grafts are then used to give more density, starting behind the new hairline and finishing at the back crown area
maxi Maxi Graft - Approximately 6 to 8 Hairs
Maxi grafts are used mainly for density in the back crown area along with a combination of mini grafts.

3 types of guitar practice offered by karlos, from lincoln, u.k:

  1. TRAINING THE HANDS: training the hands is easy with enough practice. Get to know as many techniques as you can find (i.e. sweeping ,tapping , legato and so on) once you've learned enough and know the theory behind what's been learned, riffs you once thought were impossible and incredible will just make you think "oh he's sweeping that or that's tapped "Music sound totally different when you know how it's done and it works.
  2. TRAINING THE MEMORY: this includes stuff like learning chord positions, scale positions chord shapes and such-like, if your stuck playing from a pentatonic box it may be because your playing from memory.
  3. TRAINING THE IMAGINATION: this is the part some people forget (including me until recently)... think of a note and then play it, if you keep doing this and getting more adventurous at it, you will soon be able to play anything you can imagine. If you just sound like a bunch of scales joined together then you also are playing from memory. A quick exercise for the tab is to play a note and imagine the next note down or up (making sure you get the correct note and pitch).

An alternative approach to deducing the presence of "threes" in guitar playing (as a specific music instrument reference) is identifying the usage as an exercise, though other models of exercise are to be noted as well.

3 dial slot machine

3 dial slot machine colloquially referred to as a one arm bandit because the odds of matching all 3 dials with the same object are considered to be extremely high, and therefore benefit the gambling establishment. One must wonder why people sometimes spend hours looking at three items revolving around. Is this due to some sort of cognitive symbolic link with the three moments of the Sun (dawn- noon- dusk) "revolving"? And this is also reflected in watching a little ball revolving in a roulette wheel, or individual bets "revolving" around a group of players?

Three airlines were approved of by the U.S. to adopt a marketing partnership (01-17-03):

  1. Delta
  2. Northwest
  3. Continental...

...but only on strict conditions intended to limit anticompetitive behavior. The partnership, which is known as a code-sharing alliance and was approved by the Transportation and Justice Departments, would permit the carriers to sell seats on one another's flights and allow passengers to choose which frequent-flier program would be credited with miles flown. Passengers would also be able to use the other airlines' airport lounges. Advertisement In a sharply worded statement, the Transportation Department said the partnership, which was proposed in August, raised "serious competitive issues" that could open the door for potential price and scheduling collusion. To prevent that, the department set several restrictions, including what the airlines' executives could discuss with one another, how the carriers could market themselves to corporate clients, the number of gates they could keep at airports and the types of routes the alliance could serve. The three airlines said they were studying the Transportation Department's conditions and had no further comment. Some industry experts said they would be surprised if the carriers agreed to such strict conditions, though others pointed out that the airlines did not have much to lose. Opponents of the partnership, including several low-cost airlines, praised the decision and said it was a good first step to maintaining competition. In its decision, the Transportation Department noted that the three airlines accounted for 35 percent of revenue per passenger mile in the industry and that 3,214 of their routes overlapped.

$3.00 to the Presidential campaign fund (from taxes) is a query on U.S. Federal Income Tax Forms. In the State in which I live, there is a query of whether or not a citizen would like to have $2.00 go to a political party (one of those listed on the form), or would they like to make a contribution to a particular organization (one of those listed on the form). A contribution to a political party does not reduce one's tax refund, but contributing to one of the other organizations will do so. In other words, you can give freely to political parties but you can not do so to other non-political organizations without an ensuing loss of money.

3 recurring arguments against using the death penalty in the U.S.:

  1. It's unfair to blacks. (The highest percentage of inmates are Blacks.)
  2. It doesn't really deter crime.
  3. Innocent people could be executed.

3 recurring rebuttals to the above 3 arguments:

  1. Most inmates are black individuals because many blacks have a primitive mindset with respect to abiding by laws. They use laws to assist them in doing whatever they want through con-games, manipulations, intimidations, playing roles of victimization, getting access to that and those which can be made to do their bidding by way of drugs, alcohol, music, sports, etc...
  2. The death penalty can not be realistically seen as a deterrent to crime unless it is used consistently, frequently, and decisively. Lack of crime deterrence is not the fault of the death penalty, it is a fault of the woefully inadequate American Justice System.
  3. Innocent people are executed because the American Justice System failed to keep the innocent from being convicted in the first place.

  • OK3 is a grade received by a Navy aircraft carrier pilot for his or her landing. "OK" is an excellent landing; the "3" refers to the arresting wire.
  • Usually the pilot is shooting for the 3 wire, the third of the four arresting wires on the aircraft carrier deck. --- You can see the wires by clicking here. ---
  • Catching the 3 wire means the aircraft’s tailhook landed right in the middle of the 4 wires, a very precise accomplishment. Thus, OK3 represents utmost skill and precision in one of the most demanding environments that man places himself.
