Theme and Symbolism in American Music Essay -- Music Communication Ess

Theme and Symbolism in American Music Music defines our culture. As Americans, we listen to music while we drive our cars, are at work, doing housework, studying, etc. We have songs for special occasions: Christmas, Hanukah, birthdays, weddings, parties, etc. We have taken songs from the various cultures that make us diverse: Arabic, German, Mexican, Native American, etc. We have many genres: country, hip-hop, rap, pop, blues, jazz, rock, heavy metal, etc. And although we may think of music as simple and easy, looking at all this makes one realize how diverse and complex our music truly is. Two things that contribute to this diversity are theme and symbolism. Theme can be defined as the subject or topic of something. In relation to songs this would be the subject the author is concerned with in that particular song. By far, it is safe to say that the most popular theme in music is love. Whether it is finding love, the lack of love, lost love, or any other sub-topic of love, you will find countless songs dedicated to love. Interesting enough, the theme of love can be found in ...

Managing Employee Retention Essay

Data Quality: It is important to make sure the data you use is valid. An outlier data point can dramatically reduce the fit of a model, so it is critical that bad data points be moved. In the case of the Store24 data, we will assume that all managers have some experience, so remove any data points where the manager experience is zero. Regression Analysis First, you should run a full model for profit that includes both tenure and site location related variables. Tenure related variables are MTenure and CTenure. Site location related variables are population, number of competitors, street level visibility, pedestrian access, type of neighborhood, and whether a store stays open 24 hours. These variables are also defined on page 4 of the case Store24 (A). First you should determine if all variables contribute to our understanding of the model. Use the p-value for each coefficient to decide (a value of 0.05 is typically used to decide whether a variable should be included). If any variables are not significant, copy the worksheet, remove the variable and run the regression again. In your report you should explain how well the model fits (e.g. describes the factors that impact profit). It is not commonly understood how to evaluate the â€Å"impact† of the independent variables. The variables have to have a p-value that is significant (otherwise we can’t say there is a relationship), but how small the p-value is does not tell us how important the variable is. A good way to understand the impact of the variable is to find the range of values it can take, and then multiply that range by the value of the coefficient. That tells you the maximum impact that the variable can have on the problem. Next, you must address Tom Hart’s hypothesis that manager tenure does not have a linear impact on profitability—that is, that there are diminishing returns to manager tenure. To test this, copy the worksheet, then add the variable MTenure2. To do this, insert a column next to the Tenure column, and then enter the formula =D2^2 in cell E2 and copy this formula to the rest of the cells. Now run a regression on this new set of variables and see if the MTenure2 variable is statistically significant. What to Submit: You are to write a memo from Sarah Jenkins to Paul Doucette summarizing your results. You should explain your regression results: * How well the model predicts store performance (r2, p-value of variables and their â€Å"impact†) * How your MTenure2 assesses Tom Hart’s hypothesis. Does it support his hypothesis? You should include a graph that shows contribution to profit of employee tenure over the range of values in the data set. The x-axis should be manager tenure, and the y-axis should be the predicted contribution to store profit. Finally, your memo should give Paul Doucette a concrete recommendation as to how much Store24 should invest in any new manager retention programs.

How to Develop Language in a Child with Autism - 2613 Words

Do social interactions between children and parental involvement help foster language development in six-year-old autistic children? I feel that this topic is very important because autism now affects one in 88 children, autism is the fastest growing serious developmental disability in the U.S, boys are five times more likely to get it than girls, and only 58% of students with autism finish high school. Not just that but there is still no information found on what are the causes of autism (Autism Speaks, 2013). I will use research that demonstrates that parental involvement and social interactions does help foster language development in six-year old autistic children. Theoretical Framework The research intervention was developed and based†¦show more content†¦For example, Kasari and colleagues (Kasari, Freeman, Paparella, 2006) did a study with 58 children with autism that ranged from ages three to six years old. The children were randomized to a joint attention intervention, a symbolic play intervention, or control group. Interventions were conducted for 30 minutes daily for six weeks. Both structured assessments of joint attention and play skills and mother child interactions by independent assessors. From their study they found out that both intervention groups improved significantly over the control group on certain behaviors. â€Å"The children in the joint attention intervention initiated significantly more showing and responsiveness to joint attention on the structured joint attention assessment and more child initiated joint attention in the mother-child interaction†(Kasari et al., 2006. p. 613). The way that this research relates to my study i s that it demonstrates that children with autism need parental involvement. From the study Kasari et al. (2006) found out that the children who were in the playgroup with their mother showed more interaction and play compared to the control group. This study shows that parental involvement in autisticShow MoreRelatedHow Do Children Develop?1195 Words   |  5 PagesHow do children develop?
