  • The NCRP has long recognized the need for a clear assessment of the magnitude of doses from various sources of radiation to which the population of the U.S. is exposed. In anticipation of the need to gather data for input into this process, five assessment committees, each addressing a different source category, were established. NCRP reports assessing exposures from natural background, consumer products, nuclear power generation, and diagnostic medical radiation have been published (NCRP, 1987a,b,c,d, NCRP, 1989)....

  • In this chapter, you should now be able to: Define and distinguish between the following sets of terms: density and dispersion; clumped dispersion, uniform dispersion, and random dispersion; life table and reproductive table; Type I, Type II, and Type III survivorship curves; semelparity and iteroparity; r-selected populations and K-selected populations. This chapter also explain how ecologists may estimate the density of a species, explain how limited resources and trade-offs may affect life histories,...

  • Mathematics in Action: Prealgebra Problem Solving, Third Edition, is intended to help college mathematics students gain mathematical literacy in the real world and simultaneously help them build a solid foundation for future study in mathematics and other disciplines. Our authoring team used the AMATYC Crossroads standards to develop a three-book series to serve a large and diverse population of college students who, for whatever reason, have not yet succeeded in learning mathematics.

  • Overharvesting has led to severe reductions in the abundance and range of nearly every large vertebrate species that humans have ever found worth pursuing. These megafaunal reductions, dating in some cases from first contact with early peoples (Martin 1973), are widely known. In contrast, remarkably little is known about the ecological consequences of megafaunal extirpations. Whales and whaling are part of that legacy. Most people know that large whales have been depleted, but little thought has been given to how the depletions may have influenced ocean ecosystems.

  • The subspecialty of population pharmacokinetics was introduced into clinical pharmacology / pharmacy in the late 1970s as a method for analyzing observational data collected during patient drug therapy in order to estimate patient-based pharmacokinetic parameters. It later became the basis for dosage individualization and rational pharmacotherapy. The population pharmacokinetics method (i.e., the population approach) was later extended to the characterization of the relationship between pharmacokinetics and pharmacodynamics, and into the discipline of pharmacometrics.

  • The term Business Angel has only been used in Germany since the early 1990s. According to the German Business Angel network BAND, German Business Angel associations/federations have approximately 1,400 registered members. Most of the actors are “silent angels”, this means they do not look for publicity and most of them are not organised in networks. The “Promotion Angels” are a minority - they are looking for publicity and are participating in public discussions (Harrer, 2010b).

  • The path trailed by the composer up until then, however, was littered with obstacles. On returning to Rio de Janeiro from Manaus, Villa-Lobos began to earn his living by working as an orchestra musician in symphonic societies, cinemas and cafés. Simultaneously, he hung out with the city’s street musicians, the ‘chorões,’ most of them low-level public employees who played at night at events such as baptisms, marriages and birthdays held at suburban houses.

  • Our first set of results does not allow the effect of an MBA to vary across the three types of programs or with program quality. Table 5 presents the results for men. The OLS results without ability controls yield an estimate of a 9.4% return for obtaining an MBA. The return falls to 6.3% when GMAT scores and undergraduate grades are included in the regression. There is a positive and significant return to math ability but no return to verbal ability. 29 For males, one standard deviation increase in math ability, 8.66 points, yields an 8% increase in wages. ...

  • Over the years, a wide variety of methods have been developed to reduce the chances of becoming pregnant. These methods are called birth con- trol or contraception. Birth control helps a couple plan if and when to have a child. However, birth control gained even more importance in the late twentieth century for two additional reasons. The world’s human population is growing faster than at any other time in history. For example, in 1800, Earth supported a population of almost 1 billion people. By the year 2000, the human pop- ulation reached 6 billion.

  • In Kenya, where an estimated $649 million is sent annually from the United Kingdom alone, (Kabbucho, Sander and Mukwana, 2003), there is an active network of microfinance institutions in the country, but they are restricted by law from offering money transfers. Courier and bus companies, such as Akamba Bus Services and Securicor Courier are popular ways of sending money in cash. Finally, the hawala system remains prevalent in Kenya (Kabbucho, Sander and Mukwana, 2003).

  • Accordingly, for the purpose of impact assessment, it was decided not to use response functions from daily mortality time-series studies to estimate the excess annual mortality but the change in the long-term mortality rates associated with ambient air pollution. 5 Contrary to the exposure function which is assumed to be the same for all countries, the health outcome frequency (frequency with which a health outcome appears in the population for a defined time span) may differ across countries. These differences may result from a different age structure or from other factors (i.e.

  • Ouandja Sudanese refugee camp has shown that 32% of children suffer from SAM. In addition, HIV rate prevalence (6.2%) is amongst the highest in the region and with a third of the population completely lacking access to clean water and sanitation facilities; preventable diseases are wreaking havoc amongst CAR’s vulnerable and conflict-affected populations. Only 51% of children get the opportunity to attend primary school, the figure is much lower in CAR’s conflict affected prefectures where the majority of schools are closed due to the ongoing instability.

  • Both versions of synthesis allow inclusion and estimation of spawner-recruitment functions. When detailed age composition data are lacking, the estimated spawner-recruitment curve can be used to generate the entire time series of recruitments, thus turning synthesis into a simple production model. At the other extreme, inclusion of the spawner-recruitment curve in data-rich models allows estimation of this curve while taking into account all available information.
