  • This book consists of eight chapters, which are broadly divided into two themes. The first five chapters examine design features and management practices of selected agroforestry practices, and their effects on ecosystem functions and productivity. In the first Chapter, Rodríguez-Estéz et al. provide a synthesis of existing knowledge on the ecology of the dehesa, a Mediterranean agrosilvopastoral system, and how the Iberian pig production system enhances biodiversity and ecosystem services....

  • Paradoxically, skin is both a primary barrier to systemic absorption of topically exposed chemicals and a portal to systemic delivery of transdermal medicaments. Knowledge of the factors that determine both extent and rate of chemical flux across the skin is an important component of both toxicology and pharmacology studies. The aim of this book is to provide current approaches and techniques by which dermal absorption may be quantitated utilizing end points relative to these two disciplines.

  • Next, we examine predictability in both benchmark returns and fund risk loadings. Consider the dogmatist who believes in such a predictability structure (PD-2). This investor would experience a nontrivial utility loss of 15.1 basis points per month (1.8%/ year) in December 2002 if forced to hold the optimal portfolio of the ND. The utility loss is even larger over the course of all 276 monthly investments. This loss averages 21.1 (39) basis points per month over expansions (recessions).

  • While the above-described uses (and potential uses) of social media by insurance companies are important to note, it must be pointed out there is another side of the proverbial coin to social media in insurance. A not-insignificant number of insurance companies — concerned about the novelty of the medium, the lack of explicit regulatory and legal guidance, and very real practical and technical issues — have either banned the use of social media outright or taken an approach of benign disregard relative to the use of social media in connection with their...

  • In determining what a normal production level is for an insurable farmer, USDA requires the producer to present actual annual crop yields (usually stated on a bushel-per-acre basis) for the last 4 to 10 years. The simple average of a producer’s annual crop yield over this time period then serves as the producer’s actual production history (APH). If a farmer does not have adequate records, he can be assigned a transition yield (T-yield) for each missing year of data, which is based on average county yields for the crop.

  • The engineering profession must adapt to the new low carbon paradigm well ahead of society as a whole in order to provide the necessary leadership in design and the direction of policy. The professional engineering institutions and trade associations must all recognise a multi-disciplinary, problem solving approach that over-turns conventional partisan relationships and embraces a systemic approach to construction. All contributors to construction projects must be prepared to provide leadership in their area of expertise, but work with others to link knowledge across existing boundaries.

  • Hospitals, hit hard by the Great Depression, rushed to embrace plans for prepaid health care as a way to survive. In 1939 the American Hospital Association began allowing plans that met its standards to use the Blue Cross name and logo. State legislatures agreed not to treat Blue Cross plans as insurance, based on the rationale that they were owned by hospitals. This permitted Blue Cross plans to operate as non-profit corporations, escaping the 2% to 3% premiums generally charged private insurance companies, and exempted them from insurance company reserve requirements.

  • In the future, the housing sector is expected to continue growing steadily.

  • Diversification of the portfolio can only reduce the so-called non-systematic risk, however. The systematic risk, i.e. the interdependence of returns on changes in the overall market and/or shocks cannot be eliminated. For instance, the returns on equities and investments in specific real assets are necessarily positively correlated by the underlying economic determinants. The return on an invest- ment in equities depends e.g. on company profits and therefore also on growth.

  • Unsafe abortions contribute to 13 percent of maternal deaths, about 68,000 per year. Abortion-related complications contribute to a relatively large share of maternal deaths in Latin America and the Caribbean (where legal restrictions on abortion are common) and to a lesser degree in Asia and Africa. The case fatality rate for abortions, however, is highest in Africa. Increases in the proportion of births assisted by a skilled birth attendant have been dramatic in Southern Asia, Eastern Asia and the Pacific and (from higher initial levels) in Latin America and the Caribbean.

  • Moral judgment, or capacity to judge which alternatives are ethically acceptable and which are not and to determine the uprightness of the intention. Good behavior requires deliberation and deciding to carry out an action. Making sound moral judgments is previous to making a good decision.

  • This lab will introduce students to a simple bioassay that will allow them to explore the effects that a chemical's concentration has on the level of toxicity. By relying on morphological examination of sponges hatching from gemmules that are smaller than a millimeter in diameter, this module will help students develop their microscopy skills. Our major aim, however, is to have students strengthen their ability to design and test their own hypotheses.

  • If you’re in a rush to sell and have a car that isn’t one of the market darlings or is in rough condition, it’s gener- ally best to price it close to the market value and be prepared to take market or less to make a deal happen quickly. But if your car is one of the current hot sellers, you could probably get away with pricing it 10 to 20 percent over the market.

  • For most people, advertising a car for sale means classi- fied advertising. Classified ads can be broken into two categories: print and online. Both are good ways to sell a vehicle, although in many cases online advertising can reach a wider audience. No matter which you choose, the idea behind classified advertising is to attract poten- tial purchasers to your car, not to sell them the car with your ad. Selling is your job and is done when you talk to or meet with potential purchasers.

  • While disentangling the returns to schooling from the returns to unobserved ability is difficult, estimating the returns to college quality is harder still. No good instruments have been found for college quality, and the sample sizes of twins are often too small to obtain accurate estimates of the returns to college quality. 6 A notable exception is Berhman et al. (1996), who find that, after controlling for family background characteristics using twins, there are significant returns to attending colleges of higher “quality” in several observable dimensions.
