The "Predator" Infiltrates French Ad Building At WSU!
10/29/2010 The Predator Infiltrates French Ad Building At Washington State University! Media Contact: Matt Haugen, WSU News Service, 509-335-0487, firstname.lastname@example.org PULLMAN, Wash.— No one was safe during the noon hour Friday at WSU, as "the Predator"—from the Hollywood movies of the same name— descended on the French Administration Building. Terror and fear was struck into the souls of the defenseless humans who tried to fight their way from the brick and mortar building. Or maybe peop
Fine Filters: Filtering Solutions for Clean Water
This unit focuses on the scarcity of safe drinking water across the world, some of the science basics of water, how water can be cleaned through a series of filtration steps, and how nanofiltration can be used as a cost-effective way to solve filtration problems. Upon completing this unit, students will understand: A shortage of clean drinking water is one of the most pressing global issues: As a result of water’s bent shape and polarity, water has unique properties, such as an ability to diss

14. Demographic Transition in Developing Countries
Global Problems of Population Growth (MCDB 150) By 1950, in most of the underdeveloped world, mortality had fallen to about half its pre-modern rate. The birth rate, however, had remained high and, by 1950, was about twice the death rate. For the rest of the century, both rates fell dramatically and in parallel, maintaining the gap. The enormous excess of births over deaths in this period is known as 'the population explosion.' By 1990, the world population was growing at almost 90 million a ye
15. Female Disadvantage
Global Problems of Population Growth (MCDB 150) In East and South Asia there are many more boys than girls. Previously, this resulted from female infanticide, now it is sex-selective abortion. In those cultures, girls generally marry out of the family as teenagers and thus provide no benefit for the family that raised them. Bangla Desh is agriculturally very rich, but its population is so dense that per capita income is one of the lowest in Asia. Despite the poverty, an excellent family plannin
20. Teen Sexuality and Teen Pregnancy
Global Problems of Population Growth (MCDB 150) Rates of teen pregnancy in the US are quite high, in contrast to European countries which have much lower rates, especially those with liberal attitudes toward sexuality. Traditionally, puberty and marriage were simultaneous. Now, the many years spent in education leaves a long time between those life stages. Sex education is not particularly strong. Contraception has allowed the rate of teen pregnancy to decrease steadily in spite of the fact tha
16. Population in Traditional China
Global Problems of Population Growth (MCDB 150) China's early demographic history is similar to that of Europe; population grows only slowly due to war, disease and Malthusian resource limitation. Later, introduction of American foods allowed cultivated land to expand, but population expanded even more rapidly, leading to an extremely dense, but poor population. During this time, female infanticide was frequent, but almost all surviving girls got married. Within marriage, their fertility rate w
19. Economic Motivations for Fertility
Global Problems of Population Growth (MCDB 150) Data shows, consistently, that poor people have more children than rich people; economically speaking, children are an inferior good. Children are production goods because they do work, consumption goods because they are enjoyable, and investment goods because they support parents in old age. Jobs in the modern sector require education and health. To pay for this, parents have to focus their resources on fewer children. Complete course materials
13. Fertility Attitudes and Practices
Global Problems of Population Growth (MCDB 150) Surveys show that most women are having more children than they would prefer to have. Further, studies show that the vast majority of women know about various forms of contraception. One World Bank study has shown that family planning programs have little impact unless they are attended by improved living standards and increasing status of women.

11. Low Fertility in Developed Countries (Guest Lecture by Michael Teitelbaum)
Global Problems of Population Growth (MCDB 150) Concerns about low fertility have been present in many countries for at least 100 years. A large population was considered essential to national power. But the issue is never simply a shortage of warm bodies: overall the world population has increased dramatically over this period and untold numbers would immigrate, if allowed. The issue is the number of the 'right sort' of people, defined as those having preferred national, religious, racial, eth
2. Sex and Violence Among the Apes
Global Problems of Population Growth (MCDB 150) Chimpanzee males compete for position in a dominance hierarchy; status often depends on support from other members, including females, of the group. High ranking males have much greater sexual access to females in estrus. Males control females by physical violence and intimidation. Chimpanzees also engage in purposeful raids to kill members of other chimpanzee groups. This inter-group violence can help explain intra-group violence. To fend off att
17. Population in Modern China
Global Problems of Population Growth (MCDB 150) Families lived together in traditional China and sons remained on the land; division of family land led to tiny plots and rural poverty. Because labor was so cheap, the country did not urbanize or mechanize. The Communist government started out with a pro-natal stance, but, after experiencing the famine of the Great Leap Forward, moved strongly to fertility control. Fertility declined rapidly in the 1970s, but to counter momentum, the one-child po
18. Economic Impact of Population Growth
Global Problems of Population Growth (MCDB 150) 1) Population in China: Until recently, Chinese families did not much alter their fertility depending on life events like deaths of children. However, under government prodding and eventually coercion, fertility drops drastically in China in the 1970s, but, to counteract momentum, the One-Child Policy starts in 1979-80. 2) Population Growth and Economic Development: In Asia, rapid fertility drops have preceded economic booms by ~15 years. In this
10. Quantitative Aspects
Global Problems of Population Growth (MCDB 150) Census data is often politically influenced and hence inaccurate. The birthrate in developing countries is nearly twice that in developed countries. Most humans live in less developed countries, so the world birthrate is near the higher number. The world birthrate is two and a half times the death rate; we are not close to population stabilization. Almost everywhere, the death rate has been drastically reduced; further changes will not massively a
7. Demographic Transition in Europe; Mortality Decline
Global Problems of Population Growth (MCDB 150) European population grew only slowly during the period 1200-1700; factors include disease and wars. Human feces and rotting animal remains were not sequestered and often contaminated drinking water. Cities were so filthy that more people died in them than were born. About a third of children died in infancy, many from abandonment and lack of care during wet-nursing. Children that survived were subjected to harsh discipline to control their tendenc
9. Demographic Transition in Europe
Global Problems of Population Growth (MCDB 150) Prior to the Demographic Transition, fertility in northwestern Europe was controlled by limiting marriage. Marriage was regulated by landowners and the churches, and was not allowed unless a man had accumulated the resources necessary to support a family. Long periods of being landless, a servant, or an apprentice, precluded marriage. Once married, there was no control of fertility. But, only about half of adults were married at any given time, so
