  • These research teams study for example the impact and mechanisms of greenhouse gas emissions and atmospheric pollutant on climate, ozone depletion and carbon sinks (oceans and inland waters, forests and soil). They do research to understand the mechanisms and assess the impact of global change on the water cycle, water quality and availability, as well as soil functions and quality to provide the bases for management tools for sustainable water systems. Biodiversity and ecosystems are analysed to understand and minimise the negative impacts of human activities.

  • When planning how to reduce the threat of global warming and how to adapt to it, a very important piece of information is how intense the change will be. That implies estimating the trends of future concentrations of greenhouse gasses, and the potential future changes in temperature, precipitation, storm events and other climatic variables. These predictions are important not only to estimate the magnitude of the changes, but also to determine the uncertainty surrounding them.

  • We present measures of board structure for the restating and control samples in panel B of Table 5. The two groups of firms have similar board structures. The median board size for restating (control) firms is 7 (8) members. The median proportion of independent directors (PID) is about 71 percent in each sample. About 5 percent of the independent directors hold 5 percent or larger blocks of equity (PID5) in both groups. One striking difference between the two groups is in the incidence of an independent director with financial expertise (IDFE).

  • Messaging systems based on queuing include products such as Microsoft’s MSMQ [28]and IBM’s MQSeries [29]. The queuing model with their store-and-forward mechanisms come into play where the sender of the message expects someone to handle the message while imposing asynchronous communication and guaranteed delivery constraints. A widely used standard in messaging is the Message Passing Interface Standard (MPI) [21]. MPI is designed for high performance on both massively parallel machines and workstation clusters.

  • In gravity injection, small volumes of reagents are gravity-fed into injection well(s) over a longer application period. The distribution and dissipation of the reagents in the saturated zone is largely controlled by the site hydrogeologic conditions. The gravity injection approach may reduce some of risks associated with chemical oxidation technologies. Additionally, given its prolonged application period, the oxidants may be able to penetrate into more of the lower permeability soils to address contaminants in these areas.

  • The world economy consists of two countries, denominated home and foreign. Each country is populated by a continuum of identical households, ¯rms, and a monetary authority. House- holds consume two types of ¯nal goods, a tradable good T and a nontraded good N. The production of nontraded goods requires capital and labor, and the production of tradable consumption goods requires the use of home and foreign traded inputs as well as nontraded goods.

  • There has been substantial progress in the development of the government bond market. Key steps include a lengthening of the yield curve, reduction in external exposure and diversification of the investor base. This has been supported by improved macroeconomic conditions, foreign investors entering the fixed rate segment of local currency government debt, and well designed microstructure reforms regarding issuance policy and auction process. As shown below, the government bond market has become more resilient to various risk factors. ...

  • Understanding the forces that influence natural variation within and among populations has been a major objective of evolutionary biology for decades (Csilléry et al., 2010). It can be problematic, as natural populations may have complex demographic histories: size and range changes over time can lead to bottlenecks, fusions and expansions that leave signatures on the genetic composition of the population (Avise, 2004). Detection and analysis of genetic diversity can help us to understand the molecular basis of various biological phenomena in these natural systems.

  • I have already pointed out that there are two basic sets of capitalization tools: (1) direct capitalization and (2) yield analysis. Tool Kit #2 Direct Capitalization focuses on the income stream from a property, without taking into account appreciation in value, paying down of mortgages, or ultimate value on disposition. In this regard it differs from yield analysis (Tool Kit #3 Discounted Cash Flows), as most yield calculations take into account the cash flow during the hold period plus the cash flow from the ultimate disposition of the property (see below).

  • Economic reforms implemented since the formation of the GPA have borne positive results for the economy. Real GDP grew by about 6% in 2009 and is estimated to have risen strongly to about 9.0% in 2010, reflecting strong performances in mining (47% growth) due to rising mineral and metal prices and higher agricultural output arising from higher output of tobacco, sugar, maize and cotton. Increases in agricultural output (34% growth) have historically supported manufacturing sector production (Box 1).

  • There was a movement out of US sovereign bonds, amid net outflows of €2.1 billion and negative revaluations of €3 billion, to close at €45 billion, or 5 per cent of all investments. These negative US revaluations in euro terms were partly driven by the euro depreciating by 2.8 per cent relative to the US dollar over Q1 2012. German government bonds experienced positive net inflows of €0.9 billion and account for €17.4 billion of bond assets, but holdings still remain low relative to UK and US government bond assets. Holdings of Spanish sovereign...

  • Overall, Cambodia’s rubber export competitiveness remains weaker than that of other countries in the region, except for the Lao People’s Democratic Republic. One of the problems is that despite the application of conventional technology for the management and maintenance of rubber trees and traditional rubber clones, per- hectare rubber yield remains lower than in other countries of the region.

  • Looking at a recent Cairns Group proposal on domestic support it can be seen that they want to strengthen the Green Box provision dealing with direct payments (including structural adjustment, environment and regional assistance) while capping overall spending on direct payments under the Green Box. As well, they hope to subject certain support sub-categories in the Box to reduction commitments. The Cairns Group paper further proposes to strengthen transparency, notification and review mechanisms to ensure programs meet the criteria set out in the Green Box.

  • In a simple world of full Ricardian Equivalence, households increase their savings by the present value of future taxes needed to repay government debt. Their desired bond holdings thus rise by the exact increase in government debt issuance. Private consumption declines to offset the increase in public expenditure, leaving GDP unchanged. The long-term interest rate therefore remains constant. 5 In this stylised view, changes of the government debt/GDP ratio should not affect the future path of interest rates, nominal or real, in any way at all.

  • The Blacksmith Institute’s database contains almost 350 sites contaminated with mercury, putting close to 10 million people at risk from the identified sites. It is the second most prevalent pollutant in the database. The top sources of mercury pollution are artisanal gold processing, mining and ore processing, coal mining, processing and localized air pollution related to coal combustion at poorly controlled sites, and chemical manufacturing, notably for older chlor-alkali plants making chlorine. Artisanal mining of gold ores and processing using mercury is common worldwide.
