It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological,etc.  - A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves. Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, and dominate the local economy. Some ports have an important military role.  - Elizabeth Cochran Seaman (May 5, 1864  January 27, 1922), known by her pen name Nellie Bly, was an American journalist. She was also a writer, industrialist, inventor, and a charity worker who was widely known for her record-breaking trip around the world in 72 days, in emulation of Jules Verne's fictional character Phileas Fogg, and an exposé in which she faked insanity to study a mental institution from within. She was a pioneer in her field, and launched a new kind of investigative journalism.  - The New York World was a newspaper published in New York City from 1860 until 1931. The paper played a major role in the history of American newspapers. It was a leading national voice of the Democratic Party. From 1883 to 1911 under publisher Joseph Pulitzer, it became a pioneer in yellow journalism, capturing readers' attention and pushing its daily circulation to the one-million mark.  - Yellow journalism, or the yellow press, is a type of journalism that presents little or no legitimate well-researched news and instead uses eye-catching headlines to sell more newspapers. Techniques may include exaggerations of news events, scandal-mongering or sensationalism. By extension, the term "yellow journalism" is used today as a pejorative to decry any journalism that treats news in an unprofessional or unethical fashion.  - Jules Gabriel Verne ( 8 February 1828  24 March 1905) was a French novelist, poet, and playwright best known for his adventure novels and his profound influence on the literary genre of science fiction.  - Headquarters (HQ) denotes the location where most, if not all, of the important functions of an organization are coordinated.

American newspapers began as modest affairsa sideline for printers. They became a political force in the campaign for American independence. Following independence the first article of U.S. Constitution guaranteed freedom of the press and the American press grew rapidly during the First Party System (1790s-1810s) when both parties sponsored papers to reach their loyal partisans. From the 1830s onward the Penny press began to play a major role in American journalism and technological advancements such as the telegraph and faster printing presses in the 1840s helped expand the press of the nation as it experienced rapid economic and demographic growth. Editors typically became the local party spokesman, and hard-hitting editorials were widely reprinted.  By 1900 major newspapers had become profitable powerhouses of advocacy, muckraking and sensationalism, along with serious, and objective news-gathering. During the early 20th Century, prior to rise of television, the average American read several newspapers per-day. Starting in the 1920s changes in technology again morphed the nature of American journalism as radio and later, television, began to play increasingly important competitive roles.  - Joseph Pulitzer (born József Pulitzer; April 10, 1847  October 29, 1911) was a Hungarian-American newspaper publisher of the "St. Louis Post Dispatch" and the "New York World".

INSEE, the French Statistical Institute, uses the term "unité urbaine", which means continuous urbanized area. However, because of differences in definitions of what does and does not constitute an "agglomeration", as well as variations and limitations in statistical or geographical methodology, it can be problematic to compare different agglomerations around the world. It may not be clear, for instance, whether an area should be considered to be a satellite and part of an agglomeration, or a distinct entity in itself.  - A newspaper is a serial publication containing news about current events, other informative articles (listed below) about politics, sports, arts, and so on, and advertising.
