  • We use three models to estimate health damages from PM10. First, we use an air dispersion model to estimate each source’s contribution to annual average ambient levels of PM10 at several thousand receptor locations in Paso del Norte. Next, we use a health effects model to estimate the number of cases of human mortality and morbidity that result from this pollution each year. Finally, we use a valuation model to calculate the dollar values of these health impacts. This section briefly discusses each of these models. A more detailed discussion is available in Blackman et...

  • Unfortunately, to our knowledge, direct estimates of Mexican WTP for reductions in the health endpoints considered in this paper are not yet available. Therefore, we use WTP parameters (for adult respiratory symptom days, adult reduced activity days, asthma attacks, and chronic bronchitis) that are based on U.S. studies. But given that average income adjusted for purchasing power parity is approximately four times as high in the United States as in Mexico, Mexican WTP may be lower than American WTP. Cultural factors may also cause WTP in the two countries to differ.

  • Despite often clearly definable characteristics, however, it is important to remember that genres are not fixed entities, but are instead constantly evolving. Often the boundaries between genres become blurred. In most cases films represent a “genre hybrid” – or a combination of attributes from several different genre backgrounds. Studying genre reveals a pattern of repetition and difference. In other words, some films do have identifiable similarities, but they also contain new elements or similar elements used in new ways.

  • Your employer may offer a group long-term care insurance plan or offer individual policies at a group discount. An increasing number of employers offer this benefit,16 especially since the passage of the Health Insurance Portability and Accountability Act (HIPAA). HIPAA allows employers the same type of federal tax benefit when they pay for their employees’ long- term care insurance as when they pay for their health insurance (except for Section 125 cafeteria plans).

  • In the vascular system, estrogen and serotonin have been shown to individually alter clotting, cholesterol, vasocon- striction, and heart attacks. Both high and low levels of E2 have been associated with increased risk of thromboem- bolism; high levels result in increased clot formation, while low levels result in slower clot breakdown. Unusu- ally high concentrations of estrogen (beyond normal physiological levels) directly increase the likelihood of clotting by increasing production of clotting factors VII through X in the liver [41].
