Dit gaan byvoorbeeld oor Julie-geelmielies of Desember-koffiebone en sulke kontrakte word plaaslik verhandel sowel as op internasionale markte soos die Chicago Board of Trade (CBOT), Dalian Commodity Exchange (DCE) in Sjina, die London Metal Exchange (LME) of die New York Mercantile Exchange (NYMEX) om maar net die vernaamstes te noem.

Terwyl ek dié ietwat onverwagse optrede nagevors het, het ek afgekom op ‘n ryk soom van Finse interpretasies van dié liedjie. Hier is hulle. Daar is ook Jingisukan, ‘n onlangse Japanese rendisie indien dit alles nie genoeg is nie.

Dié pamflet, wat versterkende leesstof vir die pessimis is, wys op die meetkundige (soos 2; 4; 8; 16; 32; 64; ...) aard van bevolkingsgroei teenoor die waarneming dat landboukundige produksie geneig is om line… Thu, 15 Mar 2007 22:23:47 +0200 http://www.kolmogorov.net/php/doku.php?id=perverse&rev=1175355978 The government of South Africa takes comfort in the finding of a recent report, regarding possible perverse incentives in the Child Support Grant (CSG), that the quantitative analysis suggests that the take-up rate of the CSG by teenage mothers remains low. Teenagers (younger than 20 years) represent 5 of all CSG recipients registered at October 2005.

However, it has a well-established reputation for bizarre, absurd, crude and cruel bureaucratic racism. Unfortunately, the country is still world-class in this area, a regrettable phenomenon that this page documents - from the ivory tower, of course.

Zotero can grab the details of a book right from an Amazon page or from an Oasis library catalogue and store the item on your own computer. As soon as Zotero detects a reference that it can handle, as small document icon is displayed in the browser’s address bar and a simple click on this icon is sufficient to capture the item in the Zotero database.
