Class (education)

A class in education has a variety of related meanings.

It can be the group of students which attends a specific course or lesson at a university, school, or other educational institution, see Form (education).

It can refer to a course itself, e.g., a class in Shakespearean drama.

It can be the group of students at the same level in an institution: the freshman class; or the group of students which graduates from the institution at the same time: the Class of 2005 (cf. alumnus/a). The term can be used in a slightly more general context, such as "the graduating class."

It can also refer to the classroom, in the building or venue where such a lesson is conducted.

In some countries' educational systems (such as Taiwan's), it can refer to a subdivision of the students in an academic department, consisting of a cohort of students of the same academic level. For example, a department's sophomores may be divided into three classes.

In countries such as the Republic of Ireland, India, Germany, and in the past Sweden, the word can mean a grade: 1st class is ages 4–5, 2nd class is ages 6–7, 3rd class is ages 8–9, 4th class is ages 9–10, 5th class is ages 10–11, 6th class is ages 11–12, and 9th class is ages 14–15.

Education (constituency)

The Education, formerly called Teaching in the colonial period, is a functional constituency in the elections for the Legislative Council of Hong Kong. Since its creation it has been held by the Hong Kong Professional Teachers' Union, the largest teachers' union in Hong Kong. It has been the functional constituency with most registered voters since 1998.

Education is the means through which the aims and habits of a group of people sustain from one generation to the next.

Social class

Social class (or simply "class"), as in a class society, is a set of concepts in the social sciences and political theory centered on models of social stratification in which people are grouped into a set of hierarchical social categories, the most common being the upper, middle, and lower classes.

Class is an essential object of analysis for sociologists, political scientists, anthropologists, and social historians. However, there is not a consensus on the best definition of the "class," and the term has different contextual meanings. In common parlance, the term "social class" is usually synonymous with "socio-economic class," defined as "people having the same social, economic, or educational status," e.g., "the working class"; "an emerging professional class." However, academics distinguish social class and socioeconomic status, with the former referring to one’s relatively stable sociocultural background and the latter referring to one’s current social and economic situation and, consequently, being more changeable over time.

Skipjack-class submarine

The Skipjack class was a class of United States Navy nuclear submarines (SSNs) that entered service in 1959-61. This class was named after its lead ship, USS Skipjack. The new class introduced the teardrop hull and the S5W reactor to U.S. nuclear submarines. The Skipjacks were the fastest U.S. nuclear submarines until the Los Angeles-class submarines, the first of which entered service in 1974.

Design

The Skipjacks' design was based on the USS Albacore's high-speed hull design. The hull and innovative internal arrangement were similar to the diesel-powered Barbel class that were built concurrently. The design of the Skipjacks was very different from the Skate-class submarines that preceded the Skipjacks. Unlike the Skates, this new design was maximized for underwater speed by fully streamlining the hull like a blimp. This required a single screw aft of the rudders and stern planes. Adoption of a single screw was a matter of considerable debate and analysis within the Navy, as two shafts offered redundancy and improved maneuverability. The so-called "body-of-revolution hull" reduced her surface sea-keeping, but was essential for underwater performance. Also like Albacore, the Skipjacks used HY-80 high-strength steel, with a yield strength of 80,000 psi (550 MPa), although this was not initially used to increase the diving depth relative to other US submarines. HY-80 remained the standard submarine steel through the Los Angeles class.

New South Wales 85 class locomotive

The New South Wales 85 class were a class of 10 electric locomotives built by Comeng, Granville between May 1979 and July 1980 for the Public Transport Commission.

When introduced they were the most powerful locomotives in Australia with a rating of 2,880 kW. Based at Lithgow depot they were purchased principally to haul coal trains over the Blue Mountains line. They also hauled other freight trains and on occasions passenger services including the Indian Pacific.

Following the Illawarra line being electrified in 1986, 85s began to operate coal trains from Lithgow through to Port Kembla. They also occasionally hauled coal services from Glenlee Colliery on the Main South line to Port Kembla and Rozelle. They did not operate on the Main North line although in 1993 all were hauled to Taree for repainting at Landsdowne Engineering.

A combination of National Rail electing to use diesel locomotives on electrified lines and a move to an open access model in New South Wales resulting in electric traction being priced out of the market saw the need for electric traction drop. In April 1998, the 85 class were withdrawn and stored at Lithgow.
