  • Social funds should not replace the public sector in tasks that are the government’s inherent responsibility. To do so can undermine ongoing public sector reform and institution-building programs. The objective of funds should be to reinforce and broaden, rather than supplant, the role of state institutions in the social field. Undoubtedly, in many countries, fund portfolios are going to continue to have schools and health posts and other such social projects because funds have been shown to be effective in that role.

  • Income statements in the accounting world focus heavily on revenue as a function of company volume and as a measure of company growth. The principal source of revenue for insurance companies is premium from insurance sales. (The other principal source of revenue for insurers is typically investment income.) The timing of when a company can recognize sales revenue in its income statement is a major issue for most accounting systems.

  • Empirical evidence suggests that movements in international relative prices (such as the real exchange rate) are large and persistent. Nontraded goods, both in the form of ¯nal consumption goods and as an input into the production of ¯- nal tradable goods, are an important aspect behind international relative price movements. In this paper we show that nontraded goods have important impli- cations for exchange rate behavior, even though °uctuations in the relative price of nontraded goods account for a relatively small fraction of real exchange rate movements.

  • Keynes’s liquidity preference theory touched on the maturity transformation issue. He argued that the private sector’s willingness to assume liquidity and maturity risks is not well-anchored in fundamentals. Instead it is strongly influenced by subjective factors. Hence his policy prescription was that government debt issuance should “accommodate the preferences of the public for different maturities”. It was, he argued, socially desirable that risk-averse investors should be offered some minimum, safe return on their capital.

  • Magnetotelluric surveys (soundings) are a naturalsource electromagnetic (EM) geophysical method that utilizes variations in the Earth’s magnetic field to image subsurface structures. A magnetotelluric sounding was attempted at Weyburn but has not produced results. Consequently, a final assessment of its utility is not available (Monea et al., 2008). Electrical resistance tomography (ERT) is a technique of imaging subsurface electrical conductivity. When deployed in time-lapse mode, it is capable of detecting conductivity changes caused by the injection of CO2.

  • The best practices described in this paper require that the Data Guard configuration be managed by the Data Guard Broker9. The Data Guard Broker is responsible for sending FAN events to client applications in order to clean up their connections to the down database and reconnect to the new production database.

  • After some further kilometres, sodium begins to increase by ion exchange at the expense of calcium, producing a natural softening of the water. Eventually, the available calcium in the water is exhausted, but sodium continues to increase to a level greater than could be achieved purely by cation exchange. As chloride also begins to increase, this marks the point at which recharging water moving slowly down through the aquifer mixes with much older saline water present in the sediments (Figure 4.1).

  • Diaspora investors tend to have different perceptions of risk than non-diaspora investors. Given their homeland connections, diaspora members may have better information about investment opportunities in their countries of origin and are less sensitive to exchange-rate risks than other investors, because they have domestic-currency obligations in their country of origin such as support payments to family members or running costs of domestic businesses, mortgages, or returns to domestic share-holders. They also may have a different time horizon.

  • Facilitate access to information on the health effects of indoor and outdoor air pollution and methods for reducing the risk. Conduct health impact assessments to determine the magnitude of the health effects associated with changes in air pollution. This information can be used to identify cost- effective measures to improve public health, identify critical uncertainties and suggest productive areas of research. Facilitate country actions to strengthen air quality management.

  • We propose a two-step inversion of three-component seismograms that ( 1) recovers the far-field source time function at each station and (2) estimates the distribution of co-seismic slip on the fault plane for small earthquakes (magnitude 3 to 4). The empirical Green’s function (EGF) method consists of finding a small earthquake located near the one we wish to study and then performing a deconvolution to remove the path, site, and instrumental effects from the main-event signal.
