Low-power Broadcasting
Low-power broadcasting is broadcasting by a broadcast station at a low transmitter power output to a smaller service area than "full power" stations within the same region. It is often distinguished from "micropower broadcasting" (more commonly " microbroadcasting") and broadcast translators. LPAM, LPFM and LPTV are in various levels of use across the world, varying widely based on the laws and their enforcement. Canada Radio communications in Canada are regulated by the Radio Communications and Broadcasting Regulatory Branch, a branch of Industry Canada, in conjunction with the Canadian Radio-television and Telecommunications Commission (CRTC). Interested parties must apply for both a certificate from Industry Canada and a license from CRTC in order to operate a radio station. Industry Canada manages the technicalities of spectrum space and technological requirements whereas content regulation is conducted more so by CRTC. LPAM stations are authorized to operate with l ...

Military Base
A military base is a facility directly owned and operated by or for the military or one of its branches that shelters military equipment and personnel, and facilitates training and operations. A military base always provides accommodations for one or more units, but it may also be used as a command center, training ground or proving ground. In most cases, military bases rely on outside help to operate. However, certain complex bases are able to endure on their own for long periods because they are able to provide food, drinking water, and other necessities for their inhabitants while under siege. Bases for military aviation are called air bases. Bases for military ships are called naval bases. Jurisdictional definition Military bases within the United States are considered federal property and are subject to federal law. Civilians (such as family members of military officers) living on military bases are generally subject to the civil and criminal laws of the stat ...

National League Of Cities
The National League of Cities (NLC) is an American advocacy organization that represents the country's 19,495 cities, towns, and villages along with 49 state municipal leagues. Created in 1924, it has evolved into a membership organization providing education, research, support, and advocacy to city leaders across America.

Trade Union
A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and Employee benefits, benefits, improving Work (human activity), working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting and increasing the bargaining power of workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as t ...

The union has 27 Local union, locals in Canada via CWA-SCA Canada () representing about 8,000 members. CWA has several affiliated subsidiary labor unions bringing total membership to over 700,000. CWA is headquartered in Washington, DC, and affiliated with the AFL–CIO, the Strategic Organizing Center, the Canadian Labour Congress, and UNI Global Union. History In 1918 telephone operators organized under the Telephone Operators Department of the International Brotherhood of Electrical Workers. While initially successful at organizing, the union was damaged by a 1923 strike and subsequent AT&T Corporation, AT&T lockout. After AT&T installed company-controlled Employees' Committees, the Telephone Operators Department eventually disbanded. The CWA's ...

American Library Association
The American Library Association (ALA) is a nonprofit organization based in the United States that promotes libraries and library education internationally. It is the oldest and largest library association in the world. History 19th century During the Centennial Exposition in Philadelphia in 1876, 103 librarians, 90 men, and 13 women, responded to a call for a "Convention of Librarians" to be held October 4–6, 1876, at the Historical Society of Pennsylvania. At the end of the meeting, according to Edward G. Holley in his essay "ALA at 100", "the register was passed around for all to sign who wished to become charter members", making October 6, 1876, the date of the ALA's founding.

Progressivism In The United States
Progressivism in the United States is a Left–right political spectrum, left-leaning political philosophy and reform movement. Into the 21st century, it advocates policies that are generally considered social democratic and part of the American Left.

Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
