'''[[Augustin-Louis Cauchy]]''' (Paris, August 21, 1789 &ndash; Sceaux, May 23, 1857) was one of the most prominent mathematicians of the first half of the nineteenth century. He was the first to give a rigorous basis to the concept of [[limit (mathematics)|limit]]. His criterion for the convergence of [[sequence]]s defines sequences that are now known as [[Cauchy sequence]]s. This notion has led to the fundamental mathematical concept of a [[completeness (mathematics)|complete space]]. The [[Cauchy condition]] for the convergence of [[series (mathematics)|series]] can be found in any present-day textbook on calculus. Probably Cauchy is most famous for his single-handed development of [[complex function theory]], with Cauchy's [[residue theorem]] as the fundamental result.


Cauchy was a prolific writer, he wrote approximately eight hundred research articles and five complete textbooks. He was a devout [[Roman Catholic]], strict ([[Bourbon (house)|Bourbon]]) royalist, and a close associate of the [[Jesuit order]].  <font size=1>[[Augustin-Louis Cauchy|['''more...''']]]</font>

The International Olympic Committee was established in order to deal with the increasing problem of doping in the sports world and follows three fundamental principals, protecting the health of athletes, respecting medical and sports ethics, and ensuring equality for all athletes. The list of '''[[drugs banned from the Olympics]]''' is determined by the World Anti-Doping Agency. The banned substances and techniques fall into the following categories: androgenic agents, blood doping, peptide hormones, stimulants, diuretics, narcotics and cannabinoids. The use of alcohol (ethanol) is banned in selected sports only during actual competition.

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.
