The purposes of this paper are 1) to determine the microbiotic cycles which occur in Lake Hefner in order to form a basis for ascertaining the effects of future additions of evaporation control chemicals on the biological life of this reservoir, and 2) to make a generalization as to the microbiotic cycles which might occur in Southwestern reservoirs.

In this study organisms that can be subcultured from lake water, using a prescribed procedure, limit, to an extent, the population, or portions of the population, that can be monitored. In essence, what is taking place is that a set of conditions is set forth and a study is made of the bacteria that will grow under these prescribed conditions.

Playboy is a magazine that, for more than a half century, has been mostly known to the wider audience for its stylized pictures of naked women. What a lot of people do not know is that the magazine, with its editor in chief Hugh Hefner in the lead, has been frontrunners in human rights. Playboy has been fighting protecting the right of freedom of speech, fighting for equal rights for all people during the civil rights movement and supported the feminist movement by funding precedent cases on abortion rights.   According to a series of text analyses by Beggan & Allison (2000, 2002b) Playboy’s editorial direction contradicted conventional definitions of masculinity. Also, the magazine portrayed its Playmates with complex identities that, in many cases, contained a number of traditionally masculine abilities. In this thesis we have done a critical discourse analysis of the Playboy interview and how the gender of its subject is portrayed by the magazine. Also, we have studied how seriously Playboy takes the journalistic mission in educating its audience, criticizing the power, and let a diversity of opinions be heard in the interview.   We found that, even though it’s easy to repudiate Playboy as a magazine for unsophisticated men that prefer objectified naked women, the Playboy interview presented a number of different people in different ages and of different gender that in many ways contradicted the traditional ways you tend to see the gender portrayed in interviews. The female subjects tends to be portrayed in ways that you normally se male subjects are portrayed, and the male ones tended to be given a complex identity that included both traditionally male and female abilities. We also found that Playboy takes the journalistic mission seriously, letting a diversity of opinions be heard even though they contradict what the magazine stands for.

This study seeks to distinguish the presence of secular change in contemporary nonmetric trait expression and explores the efficacy of morphological ancestry estimation with regards to North American indigenous groups. The study was conducted using cranial and mandibular trait data collected from two indigenous samples originating from the American Southwest: a pre-Contact sample from the American Museum of Natural History (n=150) and a modern sample from the New Mexico Decedent Image Database (n=100). To observe the modern sample, the RadiAnt DICOM viewer program was used to transform CT scan stacks into 3D models. Pearson’s chi-square analyses were used to assess the presence of statistically significant difference between nonmetric trait expression between the two samples. The analyses produced significant p-values (≤0.05) in 22 of the 24 observed traits. Using binary logistic regression equations, four models were developed to assess which traits contributed significantly to predicting group membership: Model 1 combined cranial and mandibular traits, Model 2 used seven of Hefner’s (2009) 11 macromorphoscopic traits, Model 3 used only cranial traits, and Model 4 used only mandibular traits. To evaluate the efficacy of an extant ancestry estimation method on indigenous sample, data from both the pre-Contact and modern samples were entered into the hefneR decision support system. The results indicate that the hefneR algorithm does not produce reliable ancestry estimates for either pre-Contact or modern indigenous samples; the samples received 14% and 11% correct classification, respectively. This study demonstrates that secular change has affected nonmetric trait expression in indigenous groups and that pre-Contact samples should not be used as proxies for modern populations.

Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly ideologically opposed businessmen, recognized this economic, political, and cultural shift and sought to capitalize on it financially. A cultural-history study of both companies revels many similarities in each company's design, development, and impact on American culture. To begin with, Disneyland and Playboy appeared in the mid-1950s as Americans were settling into postwar affluence and consumerism. Disney and Hefner each recognized the changes occurring within society and intended to design areas of reprieve. As such, Disneyland and Playboy were designed as areas of refuge where one could escape the stifling conformity of middle-class America and simultaneously forget Cold War fears. Instead, Disneyland and Playboy embraced the consensus and became reflections of society and culture rather than operatives of counter-culture. To understand how each company could fail in its original intent but remain as an emblem of American culture, it is necessary to understand the era, the men behind the visions, and how each company absorbed and reacted to cultural attitudes and strains. Disney and Hefner manipulated their way into the American cultural consciousness through a series of ironies and inconsistencies. Each sought to provide a haven of diversity as an alternative to the consensus conformity rampant within 1950s society. Ultimately, Disneyland and Playboy came to represent the homogeneity Disney and Hefner sought to escape. / Graduation date: 2002
