  • Although farmers do not receive any support from society for the contribution of the dehesa to welfare of society and the environment, they still conserve, prune and reforest oaks to maintain fruit production to feed and fatten Iberian pigs during the montanera or pannage. The ability of the Iberian pig breed to feed on acorns is a key feature in maintaining the dehesa.

  • The utility of primer pairs in SCoTs was advocated by Gorji et al. (2011). SCoT markers are generally reproducible, and it is suggested that primer length and annealing temperature are not the sole factors determining reproducibility (Gorji et al., 2011). They are dominant markers, however, while a number of co-dominant markers are also generated during amplification, and thus they could be used for genetic diversity analysis (Collard & Mackill, 2009b). This has been validated through study of genetic diversity among rice varieties (Collard & Mackill, 2009b).

  • First among the threats to forest biodiversity identified by BirdLife International and the Forest Inventory and Planning Institute (FIPI) is hunting, because of the value and rarity of the game, followed by firewood and other non- timber forest product (NTFP) collection, timber cutting, forest fires (including human-made as part of scrap metal collection) and clearance of forest land for agriculture (Le Trong Trai et al. 2001). But the threats are usually specific to each site, and detailed information is needed for each location, as we did in Khe Tran.

  • Over the next 10 years, federal spending on crop insurance is projected to outpace spending on traditional commodity programs by about one-third, which might capture the attention of budget cutters looking for potential sources of savings. Insurance companies, farm groups, and some members of Congress are concerned that additional reductions in federal support will negatively impact the financial health of the crop insurance industry and possibly jeopardize the delivery of crop insurance.

  • Under free ranging conditions, the frequency of drinking water by camel depends on a number of factors such as the ambient temperature, the water content of the feed and the physiological status of the animal. Lactating females obviously require more water than dry cows, bulls or castrates. It is said that throughout the winter period, camels may not have access to free water. There is an historial record held by camels in Sudan where it was noted 86 years ago that a large herd of camels at a well on May 11, 1917 were drinking free water for the...

  • People use social media for a number of reasons: communicating, collaborating, seeking expert advice, sharing multimedia, presenting opinions, sharing reviews and for entertainment. Many claim that social media brings a new sense of community by allowing people to connect with others who are similar to themselves. While this might involve reconnecting with long lost friends from childhood or former coworkers, it is also used to meet new friends who have similar interests. An increasing number of people are using social media in their buying decisions.

  • In later eras, new materials have been closely associated with radical change. The development of paper was as important as the printing press in revolutionising communications. The introduction of gunpowder into Europe transformed warfare. In more modern times, gas lighting only became demonstrably superior to oil and candles with the introduction of the gas mantle, composed of novel materials such as thorium and cerium oxides. A hundred years ago electric filament lamps were made possible by other novel and fairly unusual materials, osmium and tungsten.

  • It was during the Depression that hospitals band- ed together to offer prepaid coverage to citizens. Prepaid hospital coverage was a way for hospitals to avoid the financial failure that befell the banking industry. The approach worked so well that doctors followed suit a few years later and Blue Cross Blue Shield organizations were born. Little did anyone know that the seeds for runaway costs eighty years later had been planted. Prepaid, employer-provided insurance quickly dominated the health care landscape.

  • Possibilities can be explained from several semantic aspects. One way to explain possibility is ease of achievement. Another way is plausibility; that is, the propensity of an event to occur, which relates to the concept of “potential surprise”. A third way to explain possibility is logical consistency with available information. Finally, possibility can be explained as preference, referring to the willingness of an agent to make a decision. Possibility is dually related to necessity in the sense that “not A” being not possible means that A is necessary.

  • As seen in Table 7, both Planned Parenthood and other WHP clinics typically offer a comprehensive range of contraceptive methods. The methods include oral contraceptives (the Pill) as well as long-acting reversible contraceptives (LARCs) such as intrauterine devices (IUDs), implants (e.g., Implanon), or injectables (e.g., Depo-Provera). LARCs are particularly important because they are the most effective in preventing unintended pregnancies and have lower failure rates.

  • When starting hormonal contraception after POEC (Levonelle 1500® or Levonelle One Step®) additional contraception should be advised until contraceptive efficacy is established (see Summary on page iv). There are no data on quick starting hormonal contraception after use of the emergency contraceptive, ulipristal acetate (UPA) (ellaOne®). As UPA is a progesterone receptor modulator that blocks the action of progesterone, it may affect the contraceptive efficacy of hormonal methods.35,36 However, no interaction studies have been carried out to date.

  • Current average fuel economy levels vary consid- erably by country. Across the OECD the average figure in 2005 was around 8 litres per 100 km for new cars (including SUVs and minivans and in- cluding both gasoline and diesel vehicles). With a 50% fuel economy improvement, the average new car performance in OECD markets would improve to around 4 litres per 100 km (about 90 g/km of CO2).

  • Public authorities are major consumers in Europe, spending some 16 % of the EU’s gross domestic product (which is a sum equivalent to half the GDP of Germany). By using their purchasing power to opt for goods and services that also respect the environment, they can make an important contribution towards sustainable development.

  • Extraction activities disturb the land surface through clearing of vegetation, removal of topsoil, excavation of ore and overburden and the construction of over- burden dumps or solar evaporation ponds. Removal and stockpiling of topsoil for subsequent rehabilitation is carried out at many mining opera- tions. In a number of cases, topsoil is removed and placed directly on landscaped reclaimed areas. This avoids the cost of re-transporting topsoil from stock- piles and the possible reduction of biodiversity.

  • In particular, note that there are two potential sources of timing-related fund returns that are correlated with public information. The first, predictable fund risk-loadings, may be due to changing stock-level risk loadings, to flows into the funds, or to manager timing of the benchmarks. The second exploits predictability in the benchmark returns themselves. Such predictability is captured through the time-series regression in Eq. (2). Because both of these timing components are assumed to be easily replicated by an investor, we do not consider them to be based on manager ‘‘skill.

  • Article 27 of the Federal Constitution serves as the foundation for property rights in Mexico. Under Article 27, only Mexicans by birth or naturalization and Mexican corporations have the inherent right to acquire ownership of land. Even so, the state has the authority to grant foreigners the same right given to its citizens to acquire real property, but only if foreign purchasers agree not to invoke the protection of their governments in matters relating to real property.

  • From a banking group’s perspective, a range of factors play a role in the choice of branching versus subsidiarization, including banks’ business focus and differences in regulatory and tax regimes across jurisdictions. Banks with significant wholesale operations tend to prefer a more centralized branch model that provides the flexibility to manage liquidity and credit risks globally and serve the needs of large clients.
