  • In recent years, completion of the sequencing of the human genome as well as the genomes of dozens of other organisms and subsequent development of tools for comprehensive analysis of other cellular constituents have revolutionized biology. These new technologies, referred to broadly as “genomics,” have integrated biologic sciences with information sciences and engineering.

  • The guidelines are targeted at public health professionals involved in prevent- ing health risks of environmental exposures as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. The guidelines are based on the accumulated scientific knowledge available at the time of their development. They have the character of recommendations. Nev- ertheless, countries may wish to use the guidelines as a scientific basis for legally enforceable standards.

  • Socioeconomic status, poverty, and race have been found to be correlated with ACSC rates [8-10]. Several studies have examined the associations between ACSCs and demographics using small areas of analysis (typically ZIP code) and have found that ACSCs are higher in lowincome areas and areas with higher concentrations of racial and ethnic minorities [11,12]. The elderly population has not been studied much in this context, because they are thought to be relatively well-insured.

  • an effort to ensure the wise use of taxpayers’ money, the federal government has undertaken major initiatives to evaluate the performance and results of federally funded programs, including research and development (R&D) programs. The initiatives include the Government Performance and Results Act of 1993 and the Office of Management and Budget (OMB) Program Assessment Rating Tool (PART), developed in 2002. The latter was designed in the context of “performance budgeting” and “performance measurement” and focused on evaluating the efficiency of programs.

  • The National Institute for Occupational Safety and Health (NIOSH) has requested that the National Academies, through the National Research Council (NRC) and the Institute of Medicine (IOM), conduct a series of reviews of its research portfolio. The charge is discussed in detail in a subsequent section, but in general it is to evaluate the relevance and impact of a NIOSH research program and to provide recommendations for future research. This report contains a review and evaluation of the NIOSH Traumatic Injury (TI) Research Program.

  • This book is intended as a guide to the selection or design of the principal kinds of chemical process equipment by engineers in school and industry. The level of treatment assumes an elementary knowledge of unit operations and transport phenomena. Access to the many design and reference books listed in Chapter 1 is desirable. For coherence, brief reviews of pertinent theory are provided. Emphasis is placed on shortcuts, rules of thumb, and data for design by analogy, often as primary design processes but also for quick evaluations of detailed work....

  • Since all of these flavors are present in beer, it is important that beer judges completely coat the inside of their mouths with beer when evaluating it and that the beer be swallowed. As is true for the scent receptors in the nose, different people have different densities of taste buds and, thus, have different sensitivities to various flavors. Also, taste buds can be damaged (e.g., being burnt by hot food or through exposure to irritants like spicy foods, smoking, or other chemicals), so a judge’s sensitivity may be diminished until tastebuds can regenerate (about 10 days).

  • Low-affinity hemoglobins should be considered in patients with cyanosis or a low hematocrit with no other reason apparent after thorough evaluation. The P 50 test confirms the diagnosis. Counseling and reassurance are the interventions of choice. Methemoglobin should be suspected in patients with hypoxic symptoms who appear cyanotic but have a Pa O2 sufficiently high that hemoglobin should be fully saturated with oxygen.

  • Panelists from the Center for the Evaluation of Risks to Human Reproduction reviewed the literature for potential toxicities of HU. They concluded that HU does not cause a growth delay in children 5-15 years old . There were no data on the effects on subsequent generations following exposure of developing germ cells to HU in utero. Some evidence supported impaired spermatogenesis with use of HU. Although we identified six patients taking HU who developed leukemia, the evidence did not support causality.

  • Economics: Evaluation of the traffic-related health impacts and their monetarisation: Using epidemiological data regarding the relation between air pollution and morbidity and premature mortality, the number of cases of morbidity and/or premature mortality attributed to air pollution is determined for each of the health outcomes separately, using specific exposure-response functions. The same operations are carried out for the theoretical situation in which there is no road traffic-related air pollution.

  • The panel concluded that treatment of children aged 5 to15 years with hydroxyurea does not cause a growth delay. They felt there were insufficient data to allow them to evaluate the effects of hydroxyurea on pubertal development. The panel found no data regarding the effects on subsequent generations after exposure of germ cells to hydroxyurea, including exposure during fetal life, infancy, childhood, and adolescence.

  • Legal definitions of IPV reference state or federal laws and generally refer specifically to threats or acts of physical or sexual violence including forced rape, stalking, harassment, certain types of psychological abuse and other crimes where civil or criminal justice remedies apply. Laws vary from state to state. Since non-physical forms of IPV can have many medical, psychological, behavioral and developmental effects, the definition used in these Guidelines is better suited for the identification and treatment of IPV in the health care setting.

  • Health professions schools in Africa have an undeveloped culture of evaluation: although some have been evaluated by regional institutions such as the Conférence Africaine des Doyens des Facultés de Médecine d'Expression Française: African Conference of Deans of French-speaking Medical Schools (CADMEF), most have gone several decades without evaluation; the schools perceive no link between evaluation and educational reform.

  • Given the substantial findings in the area of control and cancer, it is important to explore the construct of control in greater depth. It has been argued (Shapiro, Schwartz, &Astin, 1996) that the relationship between control and health is not a simple linear one: “control is good, and the more control one has the better.”Acceptance (positive yielding) is a unique feature of control that is often overlooked in Western psychology (Shapiro & Astin, 1998), and yet, the literature demonstrates that acceptance is a crucial component in gaining an optimal sense of control.

  • Lichens are long-lived and can be monitored, field conditions permitting, in any season. Many lichens have extensive geographical ranges, allowing study of pollution gradients over large areas. These properties make them useful for spatial and temporal evaluation of pollutant accumulation in the environment. Epiphytic lichens (those that grow on trees or plants) are often best suited to the study of air pollution effects on lichen communities, lichen growth or physiology, and to the study of pollutant loading and distribution.

  • Thus, after buying into winning funds, investors unwittingly benefit from momentum returns on winning stocks. To test this reasoning, Sapp and Tiwari calculate abnormal performance following money f lows with and without accounting for the momentum factor, and find that inclusion of the momentum factor in the performance evaluation proce- dure eliminates outperformance of high f low funds. In addition, they show that investors are not deliberate in seeking to benefit from stock-level momentum: More popular funds do not have higher exposure to themomentumfactor at the time they are selected.
