  • What is the impact of damage on classic works of art from the past? It is true that we strive to preserve and repair them, but perhaps the accidents of history have the effect of renewing rather than destroying art works. Vandalized works seem strangely modern. In 1977 a vandal attacked a Rembrandt self-portrait with sulfuric acid, transforming the masterpiece forever and regrettably. 8 Nevertheless, the problem is not that the resulting image no longer belongs in the history of art. ...

  • “One size fits all” is not appropriate for poverty reduction, because con- ditions are different and because governments’ abilities are different. FOSIS in Chile, a fund that was not supported in any major way by the IDB, is a central part of the government’s machinery for poverty allevia- tion and is extremely flexible. The fund concentrates on productive projects, supports substantial microcredit activities, and imparts sub- stantial training to communities.

  • In the medium term, Zimbabwe’s prospects and performance will be largely determined by political developments and key reforms aimed at improving the investment climate especially in the areas of the property rights, indigenization, and land reform, which make up the risks to the outlook.

  • One advantage of conducting after-hours building walk-throughs to collect data on office equipment power status is that more buildings can be surveyed with a given amount of time and money. On the other hand, the data collected represents a snapshot in time, and does not capture variations in user behavior over time, which would require automated long-term time series metering of equipment power state and power levels. This is our most robust sample of buildings to date for collecting data on the after hours power status of office equipment.

  • One final word of caution. It is true that imperfect asset substitutability does give the government or the central bank an additional policy tool. But there is a qualification: Goodhart’s Law will eventually apply to debt operations. 14 The central bank may virtually fix the yield of its target bond. But if central bank action is known to have concentrated on a particular maturity, then its information content is compromised. Investors may judge that such paper is overpriced relative to paper of other maturities, and therefore avoid buying it.

  • There is a natural tradeoff in many cases between relevance and reliability. For example, the value of an infrequently traded asset may be very relevant, if the clear intent is to even- tually sell that asset to meet a liability. But the valuation of such an asset may be difficult or impossible to reliably determine. Different parties may place materially di fferent values on that asset, such that the reported value is impossible to verify by an external party or auditor. The only reliable value for the asset may be its original cost, but such a value...

  • David Smith began to exploit the potentialities of stainless steel as a medium in the 1950s. He employed this material for the creation of his Cubi, a brilliant series of twenty-eight sculptures that were destined to become the capstone of hid career. It was David Smith himself who said, “I like outdoor sculpture, and the most practical thing for outdoor sculpture is stainless steel, and I make them and I polish them in such a way that on a dull day, they take on a dull blue, of the color of the sky in the late afternoon sun, the glow, golden like the rays, the colors of nature....

  • Our study assessed the opportunity for library space saving and cost avoidance through the systematic and intentional outsourcing of local management operations for digitized books to shared service providers and progressive downsizing of local print collections in favor of negotiated access to the digitized corpus and regionally consolidated print inventory. As detailed in the report that follows, the organizational change required to achieve these gains is likely to be substantial and challenging to implement.

  • Advection is the transport of dissolved solute mass present in groundwater due to the bulk flow (movement) of that groundwater. Advection alone (with no dispersion or reactive processes occurring) would cause a non-reactive solute to advect (move) at the mean groundwater pore velocity. All solutes undergo advection, however, reactive solutes are subject to influences by other processes detailed below. Molecular diffusion is the movement of solute ions in the direction of the con- centration gradient from high towards low concentrations. It effects all solutes.

  • Sampling and analysis of local well water and surface soil gas (Strutt et al., 2005) were performed at the Weyburn field. The primary objectives of the soil gas analyses were to measure the natural background concentrations of CO2 and to ascertain whether CO2 or associated reservoir tracer gases were escaping to the near surface. Samples were collected three times over the course of two years on a regular spatial grid; additional samples that could represent possible vertical migration pathways were also collected at other sites in the surrounding area.

  • In recent years, the international community has paid attention to the water quality problem, especially since Agenda 21, which is the action plan to protect the environment, was adopted in 1992 (WHO/UNEP 1997: 10.1.1). In addition, in the United Nations Millennium Development Goals, one of the goals is to ‘reduce by half the proportion of people without sustainable access to safe drinking water’ (United Nations 2000). It has been internationally acknowledged that water problems are at a crisis point for human life as well as the environment.
