HW - Math Problem Example b. 1. What is the estimated adjusted mean difference in hourly wages for females as compared to males, adjusting for age, union membership, and job type? When age, Union Membership and type of job were taken into consideration, it was found that women earned approximately 1.9 dollars lesser per hour then men did in 1985. 2. Report a 95% confidence interval for this difference. The 95% CI for this difference ranges from -2.76 to -1.04. 3. Write a sentence interpreting both the adjusted mean difference and the corresponding confidence interval. When considering other variables like age, union membership and job type, women in 1985 earned approximately 1.9 dollars less than the men did; and 95% of the times, the actual values for this estimate would fall between 2.76 dollars to 1.04 dollars less then what the men earned on an average. 2. Comment on any disparities in the estimated mean difference in hourly wages between males and females in the four models whose results are listed above . Does it appear from these results that the wage/gender relationship in confounded by other worker characteristics such as worker age, membership in a union, and job type? Why or why not? Across the four models; it is evident that woman did earn lesser than men did per hour in 1985. This effect was seen regardless of the variables included in the study. Adjusting for age increased the discrepancy slightly; while adjusting for job type and union membership in addition to age decreased the discrepancy between the average wages of men and woman slightly. In spite of this, it is difficult to say that these variables play a very significant role; since the differences seen were quite small; and the confidence intervals for the four models overlapped quite a lot. It may be said that variable like age, union membership and job type did affect the discrepancy in the average wages of men and women; but this effect was quite small. 3. Use the results from Model D to estimate the mean differe nce in hourly wages for females, age 42, who are union members with manufacturing jobs, as compared to 42-year male union members with manufacturing jobs. (Note that you have already done this in a previous portion of the problem – I am just trying to â€Å"drill into you† how to interpret multiple linear regression coefficients.) After controlling for Union membership, type of job and age, it was found that women earned on an average, 1.9 dollars less than men in 1985. 4. 1. Does the given information allow you to assess whether the relationship between hourly wages and sex is modified by age? By itself, the data available is not enough to assess if the relationship between hourly wages and sex is modified by age. 2. If not, what additional results would you need to see? We would need information on the significance testing of the F values for the regression analyses in order to estimate whether age does truly affect the relationship between hourly wages and sex; or w hether the observed effect is simply a function of the sampled data. 2. Question two a) 1. What is the estimated adjusted association between Diastolic Blood Pressure (DBP) and

The Cultural Impact of the Yan'an Talks on Chinese Film Assignment

The Cultural Impact of the Yan'an Talks on Chinese Film - Assignment Example When he came into power, he made this belief known to the people in his 1942 speech, popularly known as the Yan’an Talks on Literature and Art. The primary purpose of the Yan’an Talks was to lay out the guidelines for literature and art in Communist China. The Talks detailed what kind of subject matter was acceptable to produce, the themes that should be discussed, and the target audience to be reached. In Chairman Mao’s words, â€Å"through the creative labour of revolutionary writers and artists, the raw materials found in the life of the people are shaped into the ideological form of literature and art serving the masses of the people† (â€Å"Talks†). The ideas outlined in the Yan’an Talks heavily influenced all forms of literature and art that emerged from China from the 1940s onwards, as evidenced by three notable Chinese films: Red Sorghum, Farewell My Concubine, and To Live. Red Sorghum, which was released in 1987 by Xi’an Film Studio, is a story that takes place in Shandong, China during World War II. It is about the life and death of a widowed sorghum distillery owner named Jiu’er. ... After some time, Li Datou dies under suspicious circumstances, and Jiu’er inherits ownership of the distillery. She is reunited with her rescuer, who has become an alcoholic whose drunkenness causes him to commit shameful acts like urinating in the sorghum wine. The story of Red Sorghum takes a darker turn at this point, with Japanese Imperial troops arriving and taking over the town. They commit various heinous acts of violence, at one point forcing one of the villagers to skin someone else alive. Angered, the people of the village revolt by attempting an ambush, during which many people, among them Jiu’er, are killed. The film makes use of bright, vivid, and detailed imagery, particularly in the violent scenes, to bring home the themes of revolution and resistance to foreign power. The Imperial Japanese troops – whom Mao named as the enemy in the Yan’an Talks – are depicted as heartless and brutal, and in the end unable to defeat the strong resist ance spirit of the villagers. The movie was also filmed with a technique that gave the entire movie a reddish tint, symbolizing both the death and violence wrought by the Japanese as well as the crimson colour of the sorghum fields which at the end of the movie are slowly growing again. Farewell My Concubine is a 1993 epic-length film that tells the story of a fifty-year friendship between two orphan boys, Douzi and Shitou, as they rise to acclaim as actors in China’s Peking Opera during the time from World War II all the way to communist China’s Cultural Revolution. Douzi is trained into female roles and assumes the stage name Cheng Dieyi, while Shitou assumes masculine roles under the name Duan Xiaolou. Eventually Dieyi’s roles translate into real life
