{{Image|Voerde Coal-fired Power Plant.jpg|right|200px|Coal-fired power plant in Voerde, Germany}}
A '''[[conventional coal-fired power plant]]''' produces [[electricity]] by [[Combustion|burning]] [[coal]] in a [[Boiler|steam generator]] that heats water to produce high pressure  and high temperature [[steam]]. The steam flows through a series of [[steam turbine]]s which spin an [[electrical generator]] to produce electricity. The exhaust steam from the turbines is cooled, [[Condensation|condensed]] back into water, and returned to the steam generator to start the process over. 


Conventional coal-fired power plants are highly complex and custom designed on a large scale for continuous operation 24 hours per day and 365 days per year. Such plants provide most of the electrical energy used in many countries.


Most plants built in the 1980s and early 1990s have a power of around 500 MW (500•10<sup>6</sup> [[watt (unit)|watt]]), while many of the modern plants have a power of around 1000 MW. Also the efficiencies (ratio of electrical energy produced to energy released by the coal burned) of conventional coal-fired plants increased from  under 35% to close to 45%.  Because of the [[second law of thermodynamics]] there is a fixed physical limit on the efficiency. By [[Carnot's law]] the limit is proportional to the temperature difference of the steam and the cooling water, with the consequence that the efficiency of a plant cannot surpass 50% by much.<font size=1>[[Conventional coal-fired power plant|['''more...''']]]</font>

The '''[[Jass–Belote card games]]''' are a family of [[trick-taking game|trick-taking]] [[card game]]s in which the Jack ("jass") and Nine of the trump suit are the highest-ranking [[trump]]s, and the Tens and Aces of all suits are the next most valuable cards. Games in this family are typically played by 2 or 4 players with the 32 French-suited cards of a [[piquet pack]].


Variants of the basic 2-handed game – known under various names including '''Klaberjas''', '''Clob''' and '''Bela''' – are played worldwide, especially in Jewish communities. 4-handed '''Belote''' with its numerous variants is the French national card game but has spread as far away as Cyprus and Saudi-Arabia. Other notable members of the family include the Swiss and Dutch national card games (Swiss '''Jass''' and Dutch '''Klaverjas'''). [[Twenty-Nine (card game)|Twenty-Nine]], a popular game in South Asia, is a descendent of these games sharing many of their characteristics. <font size=1>[[Jass–Belote card games|['''more...''']]]</font>

Featured Article: Poverty

The Mathare Valley slum near Nairobi, Kenya, in 2009.

Poverty is deprivation based on lack of material resources. The concept is value-based and political. Hence its definition, causes and remedies (and the possibility of remedies) are highly contentious.[1] The word poverty may also be used figuratively to indicate a lack, instead of material goods or money, of any kind of quality, as in a poverty of imagination.

Definitions

Primary and secondary poverty

The use of the terms primary and secondary poverty dates back to Seebohm Rowntree, who conducted the second British survey to calculate the extent of poverty. This was carried out in York and was published in 1899. He defined primary poverty as having insufficient income to “obtain the minimum necessaries for the maintenance of merely physical efficiency”. In secondary poverty, the income “would be sufficient for the maintenance of merely physical efficiency were it not that some portion of it is absorbed by some other expenditure.” Even with these rigorous criteria he found that 9.9% of the population was in primary poverty and a further 17.9% in secondary.[2]

Absolute and comparative poverty

More recent definitions tend to use the terms absolute and comparative poverty. Absolute is in line with Rowntree's primary poverty, but comparative poverty is usually expressed in terms of ability to play a part in the society in which a person lives. Comparative poverty will thus vary from one country to another.[3] The difficulty of definition is illustrated by the fact that a recession can actually reduce "poverty".

Causes of poverty

The causes of poverty most often considered are:

  • Character defects
  • An established “culture of poverty”, with low expectations handed down from one generation to another
  • Unemployment
  • Irregular employment, and/or low pay
  • Position in the life cycle (see below) and household size
  • Disability
  • Structural inequality, both within countries and between countries. (R H Tawney: “What thoughtful rich people call the problem of poverty, thoughtful poor people call with equal justice a problem of riches”)[4]

As noted above, most of these, or the extent to which they can be, or should be changed, are matters of heated controversy.
