Leaf wax n-alkane distributions in Chinese loess since the Last Glacial Maximum and implications for paleoclimate
No full textLeaf wax n-alkanes have been recently introduced into loess deposits for paleovegetation and paleoclimate reconstruction. However, the paleoclimate significance of some n-alkane parameters such as chain-length ratios (L/H, C-27/C-31, C-29/C-31, and (C-27 + C-29)/(C-31 + C-33)) remains to be clarified. In order to evaluate the validity of those proxies in loess deposits, leaf wax n-alkanes were analyzed from a northwest-southeast transect on the Chinese Loess Plateau since the Last Glacial Maximum (LGM). The n-alkanes show a bimodal distribution between C-14 and C-33 with Carbon number maxima (C-max) at C14 or C-16, and at C-31 or C-33, indicative of both terrestrial plant and microbial origin. L/H variations are in good agreement with climate changes both temporally and spatially, i.e. the higher L/H ratio the warmer and wetter climate and vice versa. Therefore, the L/H ratio in Chinese loess can serve as an efficient proxy for paleoclimate. By comparing long-chain n-alkane ratios with pollen records, we suggest that the generally used woody plant proxies (C-27 and C-29) and grass proxies (C-31 and C-33) are not applicable to Chinese loess. As the Chinese Loess Plateau was dominated by herbs in both the LGM and the Holocene, the long-chain n-alkane ratios may mainly reflect changes in the species composition of local vegetation. For a better understanding of leaf wax n-alkanes in Chinese loess, further studies are required to investigate the n-alkane distributions in both the major plant species and their associated surface soils on the Chinese Loess Plateau.

The Volatility Of Somalia’s Unregulated Exchange Rates
No full textSistem kewangan dan mata wang negara (Shiling Somalia) dahulunya stabil dan
kukuh.Walau bagaimanapun, Shilling Somalia mula merudum selepas 1980-an, dan
akhirnya tersungur ke tahap yang teruk.Kerajaan pusat negara Somalia runtuh pada
tahun 1990 selepas tiga dekad menikmati kestabilan ekonomi dan sosial. Berikutan
kegagalan itu, mata wang tersebut terus didagangkan tanpa kawalan kerajaan.
Pasaran tukaran mata wang asing tempatan pula beroperasi tanpa seliaan mana-mana
pihak.Walaupun rakyat Somalia berurus niaga mata wang dalam pasaran tersebut, ia
dikritik kerana tidak memiliki asas pasaran tukaran dagangan. Semasa tempoh
kemunduran ini, nilai Shiling mengalami fenomena ketidakaturan yang tidak boleh
dijangka, lebih-lebih lagi pada tahun 1997, 2001, 2008, dan 2011
Historically, the monetary system of Somalia was stable and its national currency
(Somali Shilling) had very strong value but Somali shilling started to depreciate after
1980s and its value reached to a very low level. Somalia’s central government
collapsed in 1990 following three decades of stability. Following the collapse of the
government, the national currency continued to circulate without sovereign support
and the country’s FX market has been operating without regulation. Though Somali
people have been using this FX market, the market is criticized of not having the
basic foundations of an FX market. During this period, the value of the Shilling
experienced unpredictable volatility in particular in 1997, 2001, 2008, and 2011
