Ebook Oil A Life Cycle Analysis Of Its Health And Environmental Impacts

Submitted by wulan on Fri, 07/31/2009 - 02:55

When significant deposits of oil were discovered in the 19th Century, this fossil fuel appeared to offer a limitless source of energy to drive development. While oil and the energy it supplies provide multiple benefits to human society, every stage in the life cycle from exploration to use can have harmful effects on our health and the environment. This re p o rt examines the health and environmental impacts of oil exploration, drilling, extraction, transport, refining and combustion.

Drilling and extraction carry acute and chronic hazards, including fires and blowouts, occupational injury and disease, and can lead to long-term harm to plant and animal communities. Oil spills and leaks along coastlines pose risks for marine life and fisheries, and can threaten the livelihoods of human communities. Refining exposes workers and wildlife to petroleum, its by product sand the chemicals used in the refining process. At the pump, gasoline can be both toxic and carcinogenic.

Ebook Merchant Processing

Submitted by wulan on Sat, 08/15/2009 - 04:35

Merchant processing is the settlement of electronic payment transactions for merchants. Merchant processing activities involve gathering sales information from the merchant, obtaining authorization for the transaction, collecting funds from the card-issuing bank, and reimbursing the merchant. The processing of sales transactions for merchants by banks does not directly affect the bank’s balance sheet except through settlement accounts and reserve balances. However, merchant processing can create significant off-balance-sheet contingent liabilities that may result in losses to the bank.

Most merchant processing transactions originate from retail credit card purchases, but debit card purchases, smart card purchases, and electronic benefits transfer (EBT) transactions are increasing sources of processing volume. In recent years, bankcard associations have aggressively promoted the move to electronic transactions through their interchange rate structure. Because of this and advances in technology, the vast majority of credit card sales transactions are now electronic.

Ebook Human Capital In Growth Regressions: How Much Difference Does Data Quality Make? An Update And Further Results

Submitted by wulan on Wed, 06/09/2010 - 07:46

Recent empirical investigations of the contribution of human capital accumulation to economic growth have often produced discouraging results. Educational variables frequently turn out to be insignificant or to have the "wrong" sign in growth regressions, particularly when these are estimated using first-differenced or panel specifications.

The accumulation of such negative results in the recent literature has fueled a growing skepticism about the role of schooling in the growth process, and has even led some researchers (notably Pritchett, 1999) to seriously consider possible reasons why educational investment may fail to contribute to productivity growth.
