Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

Stone (1751 Kent cricketer)

Stone (first name and dates unknown) was an English cricketer who played in major cricket matches for Kent in 1751.

Career

Stone played in two major matches in 1751 for Kent against the All-England Eleven. On 20 and 21 May, he was a member of the Kent team that lost by 9 runs at the Artillery Ground. A return match was arranged at the same venue on 22 May and All-England won by an innings and 9 runs, with Stone again a member of the Kent team.

Stone was also named in two single wicket "fives" matches that were held on 3 and 5 June at the Artillery Ground. In both games, he played for Kent against Surrey, Kent winning each time.

Stone is only recorded on those four occasions and it is not known if he played regularly in earlier and later seasons. Players were rarely mentioned by name in contemporary reports and there are no other known references to Stone.

In 1966, Gautrat (Stone) was taking part in the "Miss Beatnik" competition where Éric Charden was a member of the jury. They were acquainted after the competition and got married the same year. Already having separate musical careers, they decided to form the duo known as Stone et Charden in 1971. They became hugely popular "L'Avventura" in 1972 and "Made in Normandie" in 1973.

She also took part in the French musical comedy Mayflower written by Guy Bontempelli and music composed by Charden. Other actors included Pascale Rivault, Christine Delaroche, Patrick Topaloff, Gregory Ken, Roland Magdane, Roger Miremont and Mario d'Alba.

Soon artistic, mediatic and family tensions resulted in a divorce and break-up of the duo in 1975 with each member pursuing a separate sole musical career. Éric Charden married Pascale Rivault, whereas Stone later married actor Mario d'Alba with whom she had 2 children, Martin and Daisy.

Vision statement

A vision statement is a declaration of an organization's objectives, ideally based on economic foresight, intended to guide its internal decision-making.

Definition and structure

A vision statement is a company's road map, indicating both what the company wants to become and guiding transformational initiatives by setting a defined direction for the company's growth. Vision statements undergo minimal revisions during the life of a business, unlike operational goals which may be updated from year-to-year. Vision statements can range in length from short sentences to multiple pages. Vision statements are also formally written and referenced in company documents rather than, for example, general principles informally articulated by senior management. A vision statement is not limited to business organizations and may also be used by non-profit or governmental entities.

A consensus does not exist on the characteristics of a "good" or "bad" vision statement. Commonly cited traits include:
