Rations
Rationing is the controlled distribution of scarce resources, goods, services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one's allowed portion of the resources being distributed on a particular day or at a particular time. There are many forms of rationing, although rationing by price is most prevalent. Rationing is often done to keep price below the market clearing, market-clearing price determined by the process of supply and demand in an free market, unfettered market. Thus, rationing can be complementary to incomes policies, price controls. An example of rationing in the face of rising prices took place in the various countries where there was rationing of gasoline during the 1973 energy crisis. A reason for setting the price lower than would clear the market may be that there is a shortage, which would drive the market price very high. High prices, especially in the case of necessities, are undesirable with regard to those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Emergency Management Agency
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle ''Columbia'' in the 2003 return-flight disaster. While on-th ...

First Come, First Served
Queueing theory is the mathematical study of waiting lines, or queues. A queueing model is constructed so that queue lengths and waiting time can be predicted. Queueing theory is generally considered a branch of operations research because the results are often used when making business decisions about the resources needed to provide a service. Queueing theory has its origins in research by Agner Krarup Erlang when he created models to describe the system of Copenhagen Telephone Exchange company, a Danish company. The ideas have since seen applications including telecommunication, traffic engineering, computing and, particularly in industrial engineering, in the design of factories, shops, offices and hospitals, as well as in project management. Spelling The spelling "queueing" over "queuing" is typically encountered in the academic research field. In fact, one of the flagship journals of the field is ''Queueing Systems''.

Supply And Demand
In microeconomics, supply and demand is an economic model of price determination in a Market (economics), market. It postulates that, Ceteris paribus, holding all else equal, in a perfect competition, competitive market, the unit price for a particular Good (economics), good, or other traded item such as Labour supply, labor or Market liquidity, liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. The concept of supply and demand forms the theoretical basis of modern economics. In macroeconomics, as well, the AD–AS model, aggregate demand-aggregate supply model has been used to depict how the quantity of real GDP, total output and the aggregate price level may be determined in equilibrium.

Siege Of Lucknow
The siege of Lucknow was the prolonged defence of the British Residency within the city of Lucknow from rebel sepoys (Indian soldiers in the British East India Company's Army) during the Indian Rebellion of 1857. After two successive relief attempts had reached the city, the defenders and civilians were evacuated from the Residency, which was then abandoned. Background to the siege The state of Oudh/Awadh had been annexed by the British East India Company and the Nawab Wajid Ali Shah was exiled to Calcutta the year before the rebellion broke out. This high-handed action by the East India Company was greatly resented within the state and elsewhere in India. The first British Commissioner (in effect the governor) appointed to the newly acquired territory was Coverley Jackson. He behaved tactlessly, and Sir Henry Lawrence, a very experienced administrator, took up the appointment only six weeks before the rebellion broke out. The sepoys of the East India Company's Bengal Preside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Rebellion Of 1857
The Indian Rebellion of 1857 was a major uprising in India in 1857–58 against the rule of the British East India Company, which functioned as a sovereign power on behalf of the British Crown. The rebellion began on 10 May 1857 in the form of a mutiny of sepoys of the Company's army in the garrison town of Meerut, northeast of Delhi. It then erupted into other mutinies and civilian rebellions chiefly in the upper Gangetic plain and central India, though incidents of revolt also occurred farther north and east. The rebellion posed a considerable threat to British power in that region, and was contained only with the rebels' defeat in Gwalior on 20 June 1858., , and On 1 November 1858, the British granted amnesty to all rebels not involved in murder, though they did not declare the hostilities to have formally ended until 8 July 1859. Its name is contested, and it is variously described as the Sepoy Mutiny, the Indian Mutiny, the Great Rebellion, the Revolt of 1857, ...

Siege
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition warfare, attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to Surrender (military), surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "Investment (military), investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Boer War
The Second Boer War ( af, Tweede Vryheidsoorlog, , 11 October 189931 May 1902), also known as the Boer War, the Anglo–Boer War, or the South African War, was a conflict fought between the British Empire and the two Boer Republics (the South African Republic and the Orange Free State) over the Empire's influence in Southern Africa from 1899 to 1902. Following the discovery of gold deposits in the Boer republics, there was a large influx of "foreigners", mostly British from the Cape Colony. They were not permitted to have a vote, and were regarded as "unwelcome visitors", invaders, and they protested to the British authorities in the Cape. Negotiations failed and, in the opening stages of the war, the Boers launched successful attacks against British outposts before being pushed back by imperial reinforcements. Though the British swiftly occupied the Boer republics, numerous Boers refused to accept defeat and engaged in guerrilla warfare. Eventually, British scorched eart ...

Terrorism
Terrorism, in its broadest sense, is the use of criminal violence to provoke a state of terror or fear, mostly with the intention to achieve political or religious aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants (mostly civilians and neutral country, neutral military personnel). The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but became widely used internationally and gained worldwide attention in the 1970s during The Troubles, the Troubles in Northern Ireland, the Basque conflict, and the Israeli–Palestinian conflict. The increased use of suicide attacks from the 1980s onwards was typified by the 2001 September 11 attacks in the United States. There are various different definitions of terrorism, with no universal agreement about it. Terrorism is a Loaded language, charged term. It is often used with the connotation of some ...

Natural Disaster
A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Examples of natural hazards include: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane (tropical cyclone), ice storm, landslide, lightning, riverine flooding, strong wind, tornado, typhoon, tsunami, volcanic activity, wildfire, winter weather. In modern times, the divide between natural, man-made and man-accelerated disasters is quite difficult to draw. Human choices and activities like architecture, fire, resource management or even climate change potentially play a role in causing "natural disasters". In fact, the term "natural disaster" has been called a misnom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockade Of Germany
The Blockade of Germany, or the Blockade of Europe, occurred from 1914 to 1919. The prolonged naval blockade was conducted by the Allies of World War I, Allies during and after World War I in an effort to restrict the maritime supply of goods to the Central Powers, which included German Empire, Germany, Austria-Hungary and the Ottoman Empire. The blockade is considered one of the key elements in the eventual Allied victory in the war. The German Board of Public Health in December 1918 claimed that 763,000 German civilians had already died from starvation and disease, caused by the blockade.C. Paul Vincent, ''The Politics of Hunger: the Allied Blockade of Germany, 1915–1919''. Athens, Ohio: Ohio University Press, 1985. p. 141 An academic study done in 1928 put the death toll at 424,000. An additional 100,000 people may have died during the post-armistice continuation of the blockade in 1919. Both Germany and the United Kingdom relied heavily on imports to feed their population ...

Black People
Black is a racialized classification of people, usually a political and skin color-based category for specific populations with a mid to dark brown complexion. Not all people considered "black" have dark skin; in certain countries, often in socially based systems of racial classification in the Western world, the term "black" is used to describe persons who are perceived as dark-skinned compared to other populations. It is most commonly used for people of sub-Saharan African ancestry and the indigenous peoples of Oceania, though it has been applied in many contexts to other groups, and is no indicator of any close ancestral relationship whatsoever. Indigenous African societies do not use the term ''black'' as a racial identity outside of influences brought by Western cultures. The term "black" may or may not be capitalized. The '' AP Stylebook'' changed its guide to capitalize the "b" in ''black'' in 2020. The '' ASA Style Guide'' says that the "b" should not be capitalized. S ...
