Consider Example 10.7.4. Use the diagram in Figure 10.7.3 to create a Simulink model. Modify the model to use an actuator transfer function Ga(s) = 1/(0.2s + 1). Use the same gain values computed in that example. a. Plot the command response and the actuator response to a unit-step command. b. Compare the command response with that of Example 10.7.4.
2/19/16 Gender—gender is very fluid; conceptions and ideas about gender roles change o Women—the caretaker Jobs primarily dominated by women are feminized— cafeteria worker, teacher, nurse, counselor, etc. Feminization of poverty—they make up a large number of people in poverty Why are women making less than men—because of the degrees theyre getting, men tend to go into STEM;

If you left your homework at home, you deserve the bad grade. While higher class kids are encouraged to ask questions, ask for help. If you forget your homework, call me and I’ll bring it to you as a result, poor kids fall behind faster, while the upper class kids advance faster this is a product of cultural capital; both groups are working hard, but they’re doing it very differently Very different from culture of povertysays that the culture of poverty had different values (like health, school, etc.) o Differences in the home life of rich and poor children in a major factor in education o Families with more income are able to give their children more cultural capital More conducive environment Parental education o Local taxes, with additions from state and federal government Great variance $17500/student in Long Island--$8000/student in Texas o Vermont—Act 60 (1998) State pooling of local taxes and redistribution across all schools Tracking o A policy of assigning students to different educational programs o Supporters of tracking argue that tests will be used to assign students to tracks best suited to address each child’s abilities o Critics argue that tracking is a form of institutional discrimination Tracking transforms a social advantage into an education advantage Self-fulfilling prophecy Lower income kids are put into easier classes, while higher income kids are more likely to be put into more rigorous classes o We have data that shows achievement and standardized testing scores do not correlate Gender inequality o Reproduction of gender inequality in schools o Gender and educational steering by teachers, counselors, and curriculum based on cultural prescriptions of gender in society o Congress (1972) and Title IX of the Educational Amendments to the Civil Rights Act Title IX of the Educational Amendments to the Civil Rights Act—any college funding on the college campus needs to be equally disbursed o Increase in the number of women going on to college There is still a huge discrepancy into the majors/professions men and women go into Immigration: increasing diversity o Educating the more than one million immigrants that enter the US annually o English immersion versus bilingualism English immersion—teaching immigrants using English Bilingual education—policy by which schools offer classes in most subject areas in a student’s native language while also teaching them English Schooling People with Disabilities o In 1975, Congress passed the Education for All Handicapped Children Act o Mainstreaming—integrating special students into the overall educational program o Special education—schooling children with physical or mental disabilities in separate classes with specialty trained teachers The Teacher Shortage o 400000 teaching jobs remain unfilled o causes larger classes and greater burden on staff o low salaries a factor o excessive bureaucracy and school violence are also a factor school violence o has been a growing concern—homicides; aggravated assaults; rape o other types of violence—bomb threats, gang fights, cyber bullying, but shoots is a white-middle class American issue o type of school and violence larger schools urban schools poverty African American and latina students expresss greatest fear Sandy hook o
