  • In all instances, interviewees were given the option of speaking for attribution or off-the-record, and almost all respondents elected to speak off-the-record. A complete listing of the more than 100 interviewees for the overall study will be included as an appendix to the final report. The selection of interviewees considered that individuals from the bench scientist through the agency staff analyst to the politically appointed decisionmaker, as well as advocates from outside the agency, would provide informative perspectives.

  • Ideally, civil registration systems with good attribution of cause of death provide accurate data on the level of maternal mortality and the causes of maternal deaths. In countries with incomplete civil registration systems, it is difficult to measure accurately the levels of maternal mortality. First, it is challenging to identify maternal deaths precisely, as the deaths of women of reproductive age might not be recorded at all.

  • . Attribute reduction is one of the most important issues in rough set theory. There have been many scientific papers that suppose algorithms on attribute reduction. However, these algorithms are all heuristic which find the best attribute reduction based on a kind of heuristic information. In this paper, we present a new algorithm for finding all attribute reductions of a decision and we show that the time complexity of the algorithm is exponential in the number of attributes. We also show that this complexity is polynomial in many special cases.

  • The second challenge is to ensure that health is prioritized within overall development and economic policies. This means looking beyond the health system and addressing the broad determinants of ill-health - low levels of education, poverty, unequal gender relations, high risk behaviours, and an unhealthy environment - as well as raising the profile of health within national poverty reduction and government reform processes.

  • The first, most conventional way to characterize the global health picture is a description of health and disease. Today, the overall picture for child health and maternal health in poor countries is worrisome indeed. While child mortality has steadily declined in the last two decades, still approximately 10.8 million children under the age of five die each year. Progress on key indicators is slowing, and in parts of Sub-Saharan Africa, child mortality is on the rise. The great bulk of the mortality decline since the 1970s is attributable to reduction in deaths...

  • The population exposure without PM10 fraction attributable to road traffic is shown in Figure 6. Compared to total PM10, the frequency distribution changes considerably. Most people would live in areas with PM10 values less than 20 µg/m3. In France and Switzerland, less than 3% of the population would live in areas with PM10 greater than 20 µg/m3. In Austria, this portion is higher due to an increased non-traffic caused regional PM10 background.

  • Population trends affect the course of and prospects for poverty reduction. Diverse and changing population dynamics have had dramatic impacts in sev- eral world regions. Sub-Saharan Africa remains in a poverty trap where demo- graphic factors – high fertility, high infant and child mortality, and excess adult mortality (including that due to HIV/AIDS) – play significant roles. Eastern Asia, on the other hand, has seen dramatic declines in the number of persons living in income poverty.

  • Aging is accompanied by gradual cellular dysfunction associated with an accumulation of damaged proteins, particularly via oxidative processes. This cellular dysfunction has been attributed, at least in part, to impair-ment of mitochondrial function as this organelle is both a major source of oxidants and a target for their damaging effects, which can result in a reduction of energy production, thereby compromising cell function.
