A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.
Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.
A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.
There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.
There are 281 municipalities in the U.S. state of Washington. State law determines the various powers its municipalities have.
Legally, a city in Washington can be described primarily by its class. There are five classes of cities in Washington:
First class cities are cities with a population over 10,000 at the time of reorganization and operating under a home rule charter. They are permitted to perform any function specifically granted them by Title 35 RCW (Revised Code of Washington). Among them are Seattle, Tacoma, Spokane, Vancouver, and Yakima.
Second class cities are cities with a population over 1,500 at the time of reorganization and operating without a home rule charter. Like first class cities, they are permitted to perform any function specifically granted them by Title 35 RCW. Among them are Port Orchard, Wapato, and Colville.
Towns are municipalities with a population of under 1,500 at the time of reorganization. Towns are not authorized to operate under a charter. Like the previously listed cities, they are permitted to perform any function specifically granted them by Title 35 RCW. Among them are Steilacoom, Friday Harbor, Eatonville, and Waterville. In 1994, the legislature made 1,500 the minimum population required to incorporate.
Texas has a total of 254 counties, many cities, and numerous special districts, the most common of which is the independent school district.
Texas has a total of 254 counties, by far the largest number of counties of any state.
Each county is run by a five-member Commissioners' Court consisting of four commissioners elected from single-member districts (called commissioner precincts) and a county judge elected at-large. The county judge does not have authority to veto a decision of the commissioners court; the judge votes along with the commissioners (being the tie-breaker in close calls). In smaller counties, the county judge actually does perform judicial duties, but in larger counties the judge's role is limited to serving on the commissioners court and certifying elections. Certain officials, such as the sheriff and tax collector, are elected separately by the voters, but the commissioners court determines their office budgets, and sets overall county policy. All county elections are partisan, and commissioner precincts are redistricted after each ten year Census both to equalize the voting power in each and in consideration of the political party preferences of the voters in each.
In music theory, a comma is a minute interval, the difference resulting from tuning one note two different ways. The word comma used without qualification refers to the syntonic comma, which can be defined, for instance, as the difference between an F♯ tuned using the D-based Pythagorean tuning system, and another F♯ tuned using the D-based quarter-comma meantone tuning system.
Within the same tuning system, two enharmonically equivalent notes (such as G♯ and A♭) may have a slightly different frequency, and the interval between them is a comma. For example, in extended scales produced with five-limit tuning an A♭ tuned as a major third below C5 and a G♯ tuned as two major thirds above C4 will not be exactly the same note, as they would be in equal temperament. The interval between those notes, the diesis, is an easily audible comma (its size is more than 40% of a semitone).
Commas are often defined as the difference in size between two semitones. Each meantone temperament tuning system produces a 12-tone scale characterized by two different kinds of semitones (diatonic and chromatic), and hence by a comma of unique size. The same is true for Pythagorean tuning.
The Comma (Polygonia c-album) is a species of butterfly belonging to the family Nymphalidae. Its irregular wing edges are characteristic of the Polygonia genus, which is why they are commonly called anglewings. It is found in northern Africa and across Europe from Portugal through Asia as far as Japan. Its dorsal wings are colourful but its underside has a pattern that camouflages it when its wings are held together.
Polygonia c-album has a wingspan of about 45 millimetres (1.8 in). The underside of the wings of this butterfly are a dull brown colour, with a small white 'C' shaped marking resembling a comma (hence the common name). The wings have a distinctive ragged edge, apparently a cryptic form as the butterfly resembles a fallen leaf.
These butterflies hibernate, so they could be seen all around the year, but the active flying period extends from April to November, depending on location. Adults feed on nectar, mainly of Thistles (Cirsium and Carduus spp.), but also on Bramble (Rubus fruticosus), Ivy (Hedera helix), Knapweeds (Centaurea spp.), and Privet (Ligustrum vulgare).
In the terminology of the United States insular areas, a Commonwealth is a type of organized but unincorporated dependent territory.
The definition of "Commonwealth" according to current U.S. State Department policy (as codified in the department's Foreign Affairs Manual) reads: "The term 'Commonwealth' does not describe or provide for any specific political status or relationship. It has, for example, been applied to both states and territories. When used in connection with areas under U.S. sovereignty that are not states, the term broadly describes an area that is self-governing under a constitution of its adoption and whose right of self-government will not be unilaterally withdrawn by Congress."
There are currently two United States insular areas with the status of commonwealth, the Northern Mariana Islands and Puerto Rico.
Australia is a federation consisting of six states, three federal territories and seven external territories. The Australian mainland consists of five of the six federated states (with the sixth state, Tasmania, being located on an island in close proximity to the mainland) and three federal territories (including the small, somewhat anomalous Jervis Bay Territory) which constitute the world's sixth-largest country by total area. In addition, there are six island territories, known as external territories. Three of the external territories are inhabited, and the other three, besides non-permanent scientists, are uninhabited. Australia additionally claims part of Antarctica as the Australian Antarctic Territory.
All states and two of the three internal territories have their own parliaments and administer themselves; all remaining territories are administered by the federal government, but with Norfolk Island having some degree of self-government.
