Charter City
Home rule in the United States relates to the authority of a constituent part of a U.S. state to exercise powers of governance (i.e., whether such powers must be specifically delegated to it by the state—typically by legislative action—or are generally implicitly allowed unless specifically denied by state-level action). Forty of the fifty states apply some form of the principle known as Dillon's Rule, which says that local governments may exercise only powers that the state specifically grants to them, to determine the bounds of a municipal government's legal authority. In some states, known as ''home rule states'', the state's constitution grants municipalities and/or counties the ability to pass various types of laws to govern themselves (so long as the laws do not conflict with the state and federal constitutions). In other states, known as ''Dillon's Rule states'', only limited authority has been granted to local governments by passage of statutes in the state legislat ...

Papilio Rutulus
''Papilio rutulus'', the western tiger swallowtail, is a swallowtail butterfly belonging to the ''Papilionidae'' family. The species was first described by Hippolyte Lucas in 1852. Like the other tiger swallowtails, the western tiger swallowtail was formerly classified in genus ''Pterourus'', but modern classifications all agree in placing them within ''Papilio''. Distribution The western tiger swallowtail butterfly is an abundant species native to a large portion of North America’s northernmost and southernmost west coast. These butterflies are frequently observed from northwestern regions of Canada down to the southern tip of Baja California and extends eastward through states like the Dakotas, Colorado, and New Mexico. Although they primarily inhabit the west coast, it is not unusual for this species to be observed as far east as central Nebraska, even Oklahoma. These occurrences are typically rare strays outside of its usual habitat. Habitat These butterflies are f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sphere Of Influence
In the field of international relations, a sphere of influence (SOI) is a spatial region or concept division over which a state or organization has a level of cultural, economic, military, or political exclusivity. While there may be a formal alliance or other treaty obligations between the influenced and influencer, such formal arrangements are not necessary and the influence can often be more of an example of soft power. Similarly, a formal alliance does not necessarily mean that one country lies within another's sphere of influence. High levels of exclusivity have historically been associated with higher levels of conflict. In more extreme cases, a country within the "sphere of influence" of another may become a subsidiary of that state and serve in effect as a satellite state or '' de facto'' colony. This was the case with the Soviet Union and its Eastern Bloc after World War II. The system of spheres of influence by which powerful nations intervene in the affairs of others ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features, encompassing the United States and its territories; the Compact of Free Association, associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federal Information Processing Standard
The Federal Information Processing Standards (FIPS) of the United States are a set of publicly announced standards that the National Institute of Standards and Technology (NIST) has developed for use in computer systems of non-military United States government agencies and contractors. FIPS standards establish requirements for ensuring computer security and interoperability, and are intended for cases in which suitable industry standards do not already exist. Many FIPS specifications are modified versions of standards the technical communities use, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers (IEEE), and the International Organization for Standardization (ISO). Specific areas of FIPS standardization The U.S. government has developed various FIPS specifications to standardize a number of topics including: * Codes, e.g., FIPS county codes or codes to indicate weather conditions or emergency indications.

Area Codes 657 And 714
Area codes 714 and 657 are telephone area codes in the North American Numbering Plan (NANP) for the southern part of the U.S. state of California. The numbering plan area comprises northern Orange County, a portion of Los Angeles County, and the Sleepy Hollow and Carbon Canyon areas of Chino Hills in San Bernardino County. Area code 714 was assigned to a part of numbering plan area 213 in 1951, and 657 was added in 2008 to form an overlay complex. History In 1947, when the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes, the state of California was divided into three numbering plan areas: 213, 415, and 916, for the southern, central, and northern parts of the state, respectively. The area served by 213 extended from Mexican border to the Central Coast. Starting in the 1950s, Southern California experienced rapid expansion of telephone service, requiring area code 213 t ...

North American Numbering Plan
The North American Numbering Plan (NANP) is an integrated telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1, World Numbering Zone 1 and has the telephone country code, country code ''1''. Some North American countries, most notably Telephone numbers in Mexico, Mexico, do not participate in the NANP. The concepts of the NANP were devised originally during the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone companies in North America in Operator Toll Dialing. The first task was to unify the diverse local telephone numbering plans that had been established during the preceding decades, with the goal to speed call completion times and decrease the costs for long-distance calling, by reducing manual labor by switchboard operators. Eventually, it prepared the continent for direct-dialing of long-distance calls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
