Is It a Meteorite? Applying Problem-Solving Strategy to Mass Spectra and Atomic Mass
No full textIn this interrupted case study, two friends find unanalyzed mass spectra of a green rock suspected to be a meteorite. Students are tasked with identifying the elements present in the meteorite by analyzing the mass spectra. The purpose of this case is two-fold: first, to calculate the average atomic mass of elements, and second to practice problem-solving strategy. Since many students are intimidated by complex equations the calculation of the atomic mass is carried out without presenting the equation of weighted atomic mass. Students are guided to extract information from graphs and to calculate the atomic mass based on their own interpretation of the data. During the case, students are instructed to spell out the problem, the strategy to solve it, the steps required to solve the problem, and to explain why the answer does or does not make sense. The case was originally written for a principles of chemistry class and was delivered early in the semester after the introduction to atomic structure and isotopes
Stock Market Reactions to Presidential Statements: Evidence from Company-Specific Tweets
Get PDFWhen the President of the United States tweets, do investors respond? We analyze the impact of tweets from President Trump\u27s official Twitter accounts from November 9, 2016 to July 31, 2017 that include the name of a publicly traded company. We find that these tweets move company stock prices and increase trading volume, volatility and institutional investor attention, with a stronger impact before the presidential inauguration. The initial impact of the presidential tweets on stock prices appears to dissipate over the next few trading days. Overall, the results show that investors pay attention to presidential company-specific statements even when such statements have no lasting effect on shareholder value
The Effect of Conservative Politics on Sex Education and Teen Birth: A State-by-State Analysis of Abstinence and Contraception-focused Approaches
Get PDFResearchers and policy makers have looked at many factors that result in high teen birth rates, most notably sex education in public schools. Most often sex education policies fall to the state government, resulting in vast differences in policy across the US. In this study I look at two different approaches to sex education: programs in which abstinence is stressed and programs that include information on contraception. Using the Guttmacher Institute’s evaluation of state sex education laws (2015) and The National Campaign to End Teen and Unplanned Pregnancy’s teen birthrates (2015), I have compiled a data set that allows a state-by-state analysis of sex education policies and teen birthrate outcomes. I have also considered the influence of the state’s political leaning on the variables by coding states that voted for Donald Trump in the 2016 election as conservative. The findings suggest that controlling for sex education, conservative states have higher teen birthrates. While there appears to be a relationship between the type of sex education and teen birthrate, when conservative is controlled for the relationship disappears. Conservative states have higher teen birthrates than liberal states across all racial categories. Additionally, conservative states were more likely to stress abstinence in their sex education than include information on contraception. Finally, stressing abstinence in sex education has no effect on teen birthrates, while including information on contraception only has an effect on reducing the birthrate for Black teens. It appears that conservative politics may be a better indicator of teen birthrates than sex education requirements
Social Media Usage: The Impact on Feelings of Depression or Loneliness
Get PDFOver the past decade, there has been a rapid growth of social media. Much of the problem lies with the new potential for constant social comparisons. Social media also adds a new layer of interaction that can occur anywhere, at any time, with anyone. This allows for a higher quantity of relationships, but strips the depth of these relationships. Does increased social media use affect quality of life? I hypothesize that the more social media sites a respondent is a member or regular user of, the more time he or she reports feeling depressed or lonely. I used a sample of 628 respondents as part of in-person interviews conducted by the 2016 General Social Survey. The results found that overall about 51 percent of the people claimed to feel depressed or lonely none of the time. Meaning that about half of respondents do feel depressed or lonely at least some of the time. The most statistically significant finding revealed that the higher ones income, the less one reports feeling depressed or lonely. However, the hypothesis must be rejected because there is no statistical significance between social media usage and quality of life. Social media site usage does not result in increased feelings of depression or loneliness. Based on the income results, does money buy happiness? Those of lower socio-economic class may not have access to proper medical care and therefore do not get adequate treatment for mental illnesses. Structural forces might be having a direct impact

From the People’s Party to President Trump: Populism in the U.S.
Get PDFThe emergence of two populist presidential candidates within both political parties during the 2016 election cycle sent shockwaves throughout America. Populism, presented as highly foreign to the American political system by media outlets and political commentators, is increasingly received with fear and hostility; however, Americans fail to recognize the existence of a uniquely American brand of populism that consists of ephemeral actors and lasting consequences. Through a cumulative study of populist actors and their respective movements from the Populist Party of the 1890s to George Wallace\u27s American Independent Party of the 1960s and 1970s, this paper aims to identify two components of American populism that accent 2016\u27s populist platforms and to recognize populism as a complex phenomenon within the American political system. American populists engage, in varying capacities, appeals to both collective economic rights and popular prejudices
There\u27s No Place Like Home? Understanding the Relationship Between Racial Residential Segregation and Self-Reported Health
Get PDFHow does context influence health? County racial composition and racial residential segregation shape health outcomes by creating different contexts that influence access to health-related resources. White Americans disproportionately possess these material and intangible resources. Therefore, I propose that the higher the percent of non-Hispanic white residents in U.S. counties, and the higher the racial residential segregation in U.S. counties, the lower the percent of adult residents who report poor or fair health in U.S. counties. To explore these hypotheses, I analyze 2014 demographic and survey data from 2946 U.S. counties. Findings provide mixed support for my hypotheses. Percent white has a significant inverse relationship with county self-reported health. Controlling for median household income, access to health insurance and primary care physicians, and rurality, the higher the percent of white residents, the lower the percent of residents reporting poor or fair health in U.S. counties. However, the dissimilarity index has no significant relationship with the dependent variable. In both models, control variables of median household income, access to health insurance and primary care physicians, and rurality are significantly linked to self-reported health. These results suggest that the control and distribution of material (economic and political) and intangible (social and cultural) resources is key to predicting health outcomes. The concentration of resources in white communities is a critical aspect of maintaining structures of institutional racism. Changing the control and distribution of these resources will be key to overcoming widespread racial health disparities and other pervasive forms of structural racial inequality
