Flint

Flint is a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. From a petrological point of view, "flint" refers specifically to the form of chert which occurs in chalk or marly limestone. Similarly, "common chert" (sometimes referred to simply as "chert") occurs in limestone.

Origin

The exact mode of formation of flint is not yet clear but it is thought that it occurs as a result of chemical changes in compressed sedimentary rock formations, during the process of diagenesis. One hypothesis is that a gelatinous material fills cavities in the sediment, such as holes bored by crustaceans or molluscs and that this becomes silicified. This hypothesis certainly explains the complex shapes of flint nodules that are found. The source of dissolved silica in the porous media could be the spicules of silicious sponges. Certain types of flint, such as that from the south coast of England, contain trapped fossilised marine flora. Pieces of coral and vegetation have been found preserved like amber inside the flint. Thin slices of the stone often reveal this effect.

Flint station (Michigan)

Flint is an inter-modal transportation center in Flint, Michigan. It is served by Amtrak's Blue Water route, and doubles as the intercity bus station for Greyhound Lines and Indian Trails, as well as the local city bus service, the Flint Mass Transportation Authority, who owns the station.

Baggage cannot be checked at this location; however, up to two suitcases in addition to any "personal items" such as briefcases, purses, laptop bags, and infant equipment are allowed on board as carry-ons.

History

This is at least the fourth station along the Grand Trunk Western Railroad (GTW) line through Flint. The railroad arrived from Port Huron in 1871 and originally a wooden structure served as the passenger station. A 1905 stone and brick station was moved to Muskegon in 1927. The third GTW depot, located at 120 East 14th Street, was used by Amtrak until 1989 and demolished thereafter. The current station on Dort Highway provides easy access to I-69.

The International Limited was operated jointly by Via Rail and Amtrak between Chicago and Toronto. The service, which had started in 1982, was discontinued in 2004.

Flint Boroughs (UK Parliament constituency)

Flint Boroughs (sometimes known as Flint or the Flint District of Boroughs) was a parliamentary constituency in north-east Wales which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom and its predecessors, from 1542 until it was abolished for the 1918 general election.

Boundaries

From its first known general election in 1542 until 1918, the constituency consisted of a number of boroughs within the historic county of Flintshire in north-east Wales. The seat should not be confused with the county constituency of Flintshire, which existed from the 16th century until 1950.

After 1918 Flintshire was represented in Parliament by the single member county constituency, which included all the boroughs formerly in the Flint District of Boroughs.

Flint 1535–1832

On the basis of information from several volumes of the History of Parliament, it is apparent that the history of the borough representation of Wales and Monmouthshire is more complicated than that of the English boroughs.

Prescription (sovereignty transfer)

Prescription, in international law, is sovereignty transfer of a territory by the open encroachment by the new sovereign upon the territory for a prolonged period of time, acting as the sovereign, without protest or other contest by the original sovereign. It is analogous to the common law doctrine of easement by prescription for private real estate. This doctrine legalizes de jure the de facto transfer of sovereignty caused in part by the original sovereign's extended negligence and/or neglect of the area in question.

Notes

Linguistic prescription

Linguistic prescription (or prescriptivism) is the practice of elevating one variety or manner of language use over another. It may imply some forms are incorrect, improper, illogical, lack communicative effect, or are of low aesthetic value. Sometimes informed by linguistic purism, these normative practices may address such linguistics aspects as spelling, grammar, semantics, pronunciation, and syntax. They may also include judgments on socially proper and politically correct language use.

Linguistic prescriptivism may aim to establish a standard language, teach what a particular society perceives as a correct form, or advise on effective communication. If usage preferences are conservative, prescription might appear resistant to language change; if radical, it may produce neologisms.

Prescriptive approaches to language are often contrasted with descriptive linguistics, which observes and records how language actually is used. The basis of linguistic research is text (corpus) analysis and field study, both of which are descriptive activities. Description, however, may include researchers' observations of their own language usage.
