  • Difficulty in addressing contamination in low permeability soils may be alleviated to some degree by controlled pneumatic or hydraulic fracturing of the soil. However, engineered hydraulic fractures generally cannot be spaced more closely than about 5 feet, which means that chemical oxidants must still penetrate a substantial thickness of low permeability soil to come into contact with the contamination. Deep soil mixing with large diameter drill augers is the most effective method currently available to increase contact between adsorbed contaminants and the oxidants.

  • Dynamicity of participants: Some P2P systems, such as [10], assume a fixed set of nodes in the system. However, one of the greatest potential strengths of P2P systems is when they eschew reliance on dedicated infrastructure and allow peers to leave the system at will. Even under these conditions, participants typically have broadly varying availability characteristics. Some peers are akin to servers: their membership in the system stays largely static. Others have much more dynamic membership, joining and leaving the system at will.

  • Carbon offsets are an innovative tool for allowing companies and individuals to reduce greenhouse gas emissions beyond what they can easily achieve on their own. In the past two years, interest in carbon offsets has grown dramatically as companies and concerned consumers have sought ways to help mitigate climate change. However, the global market for voluntary carbon offsets is currently unregulated, which has led to growing concerns about whether buyers are really getting what they are paying for.

  • Lenne, 1996) and to decrease damage by pests and pathogens (Cantelo & Sanford, 1984). In some crops (e.g. rice) this is applied on a large scale to maximize yield by minimizing damage by pathogens (Zhu et al., 2000). Information on genetic diversity and population structure also assists plant breeding in the selection of parents for crossing, providing a more rational basis for expanding the gene pool, and for identifying materials that harbor genes of value for plant improvement.

  • The annual agriculture appropriations bill traditionally makes two separate appropriations for the federal crop insurance program. It provides discretionary funding for the salaries and expenses of the RMA. It also provides “such sums as are necessary” for the Federal Crop Insurance Fund, which finances all other expenses of the program, including premium subsidies, indemnity payments, and reimbursements to the private insurance companies. Government costs for crop insurance have increased substantially in recent years. After ranging between $2.1 and $3.

  • The SRA also defines risk-sharing between the government and private insurance companies. Under the SRA, insurance companies may transfer some liability associated with riskier policies to the government and retain profits/losses from less risky policies. 17 This transfer of risk is accomplished through a set of reinsurance funds maintained by FCIC. Within 30 days of the sales closing dates for each crop, companies allocate each policy they sell to one of two funds that are maintained for each company by state: Assigned Risk or Commercial. (The previous SRA had three funds.

  • The final risk-sharing component of the SRA is the “net book quota share,” defined as the proportion of a company’s overall gain or loss over its entire “book of business” that is ceded to the government after all other reinsurance provisions in the SRA have been applied. Under the SRA, companies must cede a 6.5% share of their cumulative underwriting gains/losses to the government. During years in which there are underwriting gains, 1.5% of this share is distributed back to companies that sell and service policyholders in 17 underserved states.

  • Notwithstanding that the AIFM must be able to provide both functions in order to be authorised, it may choose to delegate the portfolio management and/or the risk management function. In such cas- es, and as set out above, the delegation of these functions should comply with the rules set out under Article 20 of the AIFMD and the relevant Level 2 measures. Therefore, the liability of the AIFM will not be affected by the fact that the AIFM has delegated the portfolio management and/or risk man- agement functions to a third party, or by any further sub-delegation.

  • In 1992, the first United Nations Conference on Sustainable Development, popularly known as the Rio Earth Summit, was convened in Rio de Janeiro, Brazil to address the state of the environment and sustainable development. The Earth Summit yielded several important agreements including “Agenda 21”, a plan of action adopted by over 178 governments to address human impacts on the environment at local, national and global levels, and key treaties on climate change, desertification and biodiversity.

  • Prior to the 2010 renegotiation of the SRA, some observers argued that the reimbursement rate should be pegged to something other than premium value, such as the number of policies sold, to better reflect actual costs and to help reduce federal expenditures. If premiums are actuarially sound, the administrative costs of writing a policy are likely not proportional to the value of the policy (e.g., whether 10 acres or 1,000 acres, or $3 per bushel or $9 per bushel).

  • The treaty, called the Stockholm Convention on Persistent Organic Pollutants, is a major achievement. It starts by immediately targeting 12 particularly toxic POPs for reduc- tion and eventual elimination. More importantly, it sets up a system for tackling additional chemicals identified as unacceptably hazardous. It recognizes that a special effort may sometimes be needed to phase out certain chemicals for certain uses and seeks to ensure that this effort is made. It also channels resources into cleaning up the existing stockpiles and dumps of POPs that litter the world’s landscape.

  • The level of corporate profits increased in FY 2011, but at a slower pace than in the previous fiscal year. Federal spending grew and tax receipts increased in FY 2011, which resulted in the Federal unified budget deficit remaining essentially flat at $1.3 trillion. However, the deficit narrowed as a share of GDP to 8.7 percent from 9.0 percent in FY 2010. The economy continued to receive significant support during the fiscal year by a wide variety of measures implemented under the American Recovery and Reinvestment Act of 2009 (Recovery Act or ARRA). It was also...

  • Another option to consider when selling your car is word of mouth. Car collecting represents a relatively tight community, and the interconnections between its members can be very useful. When it comes time to sell your car, tell friends and other collectors with a shared interest that it’s for sale. Part of the magic of the collec- tor car hobby is that if you tell fellow enthusiasts you’re selling your car, they’ll tell their friends who share the same interests and so on. It’s not unusual for a car to sell on word of mouth alone when the informa- tion is...

  • The concept of aesthetic labour is partly seen from the perspective of ethics. There may be strictly applied selection criteria for the recruitment and selection of new employees. For an appointments panel such a situation could cause conflict between organisational requirements and personal private views on what is moral or fair. The ethical problem concerns the Human Resource manager, who wishes to appoint someone, but who needs professional reasons for appointing a less attractive person.

  • In this paper, we identify the effect of preschool exposure to television on adolescent cognitive skills by exploiting variation in the timing of television’s introduction to U.S. cities. 2 Most cities first received television between the early 1940s and the mid- 1950s. The exact timing was affected by a number of exogenous events, most notably a four-year freeze on licensing prompted by problems with the allocation of broadcast spectrum across cities. Once it was introduced, television was adopted rapidly by fami- lies with children.
