Population change

The difference between the size of the population to the end and the beginning of a period.The population change refers to change in the number of people during the specific time. The world population has not been stable. It has increased manifold. This subject is very closely related to demographics, the statistics of how many people there are in a given population.

This is actually due to changes in the number of births and deaths. For an extremely long period of human history until the 1800s, the world's population grew steadily but slowly. Large numbers of babies were born but they died early too. This was as there were no proper health facilities. Sufficient food was not available for all the people. Farmers were not able to produce enough to meet the food requirements of all the people. As a result, the total increase in population was very low.

Population growth

In biology, population growth is the increase in the number of individuals in a population. The population growth rate is the rate at which the number of individuals in a population increases in a given time period as a fraction of the initial population.

Global human population growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, where estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050.

Population growth rate

The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Specifically, population growth rate refers to the change in population over a unit time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period. This can be written as the formula, valid for a sufficiently small time interval:

Revision (writing)

Revision is the stage in the writing process where the author reviews, alters, and amends her or his message, according to what has been written in the draft. Revision follows drafting and precedes editing. Drafting and revising often form a loop as a work moves back and forth between the two stages. It is not uncommon for professional writers to go through many drafts and revisions before successfully creating an essay that is ready for the next stage: editing.

In their seminal book, The Elements of Style, William Strunk, Jr. and E.B. White acknowledge the need for revision in the writing process: “Few writers are so expert that they can produce what they are after on the first try. Quite often you will discover, on examining the completed work, that there are serious flaws in the arrangement of the material, calling for transpositions... do not be afraid to experiment with your text.”

Successful revision involves:

Identification of thesis. The purpose of the essay should be re-considered based on what has been written in the draft. If this purpose differs from the original thesis, the author must decide from which thesis to continue writing.

Revision3

Revision3 is a San Francisco-based multi-channel Internet television network that creates, produces and distributes Web television shows on niche topics. Founded in 2005, it has been operating as a subsidiary of Discovery Digital Networks since 2012. The network has primarily technology-based shows hosted and produced by Patrick Norton, and gaming shows hosted and produced by Adam Sessler. The network also creates and hosts comedic, political, DIY, and movie-related content. The name refers to the revisioning of video programming, according to founders Jay Adelson and David Prager. The first revision was cable television, adding general interest channels, catering to the "most common denominator." The second revision was PC-based Internet video, independent films, no business model, no loyalty, no audience. The third revision or Revision3 is TV and Internet converged. iPods, TiVo, mobile, and broadband enable mass, loyal audiences to shift to on-demand, niche content.

History

The company was founded in Los Angeles, California, by Jay Adelson, Kevin Rose and David Prager in April 2005. Dan Huard, Keith Harrison, and Ron Gorodetzky were also involved. Most of them were previously employees of the television network TechTV.

Mitt Romney presidential campaign, 2012

The 2012 presidential campaign of Mitt Romney, the 70th Governor of Massachusetts, was formally announced on June 2, 2011 at an event in Stratham, New Hampshire. Having previously run in the 2008 Republican primaries, Mitt Romney's campaign in the 2012 election was his second bid for the Presidency of the United States.

He filed his organization with the Federal Elections Commission as an exploratory committee and announced the organization in a video message on April 11, 2011. He became the party's presumptive nominee with his victory in the Texas primary on May 29, 2012.

On August 11, 2012, in Norfolk, Virginia, Romney announced that his running mate for vice president was Paul Ryan, the U.S. Congressman for Wisconsin's 1st congressional district.

On August 30, 2012, in Tampa, Florida, Romney formally accepted the Republican Party's nomination at the 2012 Republican National Convention.

Romney's campaign came to an end on November 6, 2012, upon defeat by incumbent President Barack Obama.

Video 2000

Video 2000 (or V2000; also known as Video Compact Cassette, or VCC) is a consumer videocassette system and analog recording standard developed by Philips and Grundig to compete with JVC's VHS and Sony's Betamax video technologies. Distribution of Video 2000 products began in 1979 and ended in 1988; they were marketed exclusively in Europe, Brazil, and Argentina.

Philips named the videotape standard Video Compact Cassette (VCC) to complement their landmark Audio Compact Cassette format introduced in 1963, but the format itself was marketed under the trademark Video 2000.

Video 2000 succeeded Philips's earlier "VCR" format and its derivatives (VCR-LP and Grundig's SVR). Although some early models and advertising featured a "VCR" badge based on the older systems' logo, Video 2000 was an entirely new (and incompatible) format that incorporated many technical innovations. Despite this, the format was not a major success and was eventually discontinued, having lost out to the rival VHS system in the videotape format war.
